  The exchange offer is subject to certain conditions described in this prospectus, including that the exchange offer does not violate applicable law or applicable interpretations of the staff of the Securities and Exchange Commission and that no injunction, order or decree has been issued which would prohibit, prevent or materially impair our ability to proceed with the exchange offer.

SUMMARY

      This summary highlights some of the information about Arch Western Resources, LLC, Arch Western Finance, LLC and Arch Coal, Inc. contained elsewhere in this prospectus. As a result, it does not contain all of the information that you should consider in deciding whether to participate in the exchange offer. You should carefully read this entire prospectus and the documents incorporated into it by reference, including the “Risk Factors” and “Forward-Looking Statements” sections and the consolidated financial statements and the notes to those statements. Unless the context otherwise indicates, as used in this prospectus the terms “Arch Western,” “we,” “our” and “us” and similar terms refer to Arch Western Resources, LLC, its wholly owned subsidiaries, including Arch Western Finance, LLC, and its 65% membership interest in Canyon Fuel Company, LLC; the term “Issuer” refers to Arch Western Finance, LLC; the term “Arch Coal” refers to Arch Coal, Inc. and its subsidiaries (including us); the term “Vulcan” refers to Vulcan Coal Holdings, L.L.C. and its subsidiaries (including Triton Coal Company, LLC); and the term “Triton” refers to Triton Coal Company, LLC. We are owned 99% by Arch Coal and 1% by an affiliate of BP p.l.c. We account for the financial results of Canyon Fuel utilizing the equity method. Coal reserves data in this prospectus includes all of the reserves of Canyon Fuel. Unless otherwise stated in this prospectus, production data for Arch Western and Arch Coal does not include Canyon Fuel production data. References to productivity in this prospectus are measured in tons of coal produced per employee shift.

Arch Western Resources, LLC

      We are one of the largest and most productive operators of compliance and low sulfur coal mines in the United States. We sold 72.5 million tons of coal in 2002 and 15.8 million tons of coal during the three months ended March 31, 2003, all of which was compliance and low sulfur. We have a total of seven operating mines. Our largest mine, Black Thunder, is located in Wyoming in the Powder River Basin, the largest and fastest-growing U.S. coal-producing region. Black Thunder is the second largest coal mine in the United States. We are the largest producer of coal in the Western Bituminous Region, where we directly own three mines in Colorado and Wyoming and a 65% interest in Canyon Fuel Company, LLC, which owns and operates three mines in Utah, one of which is scheduled to be idled by June 30, 2004.

      As of March 31, 2003, we controlled approximately 1.9 billion tons of proven and probable compliance and low sulfur coal reserves. Approximately 93.5% of our reserves is compliance coal, which does not require electric generators to use sulfur dioxide reduction technologies to comply with the requirements of the Clean Air Act.

      We sell substantially all of our coal to producers of electric power, most of whom are large, investment grade utilities. Currently, we have sales contracts in place for approximately 96% of our planned 2003 production and approximately 64% of our planned 2004 production. This provides us with a relatively reliable and stable revenue base. Our goal with respect to the remainder of our planned production is to seek long-term supply agreements with our largest and best customers as coal markets strengthen.

 
Arch Western Finance, LLC

      The Issuer is a Delaware limited liability company and an indirectly wholly-owned subsidiary of Arch Western Resources, LLC. It was formed on June 3, 2003 solely for the purpose of being the issuer of the old notes and the registered notes. The Issuer has no operations, and we do not expect that it will have operations in the future. The Issuer’s only asset is an intercompany note issued by Thunder Basin Coal Company, L.L.C., a wholly owned subsidiary of Arch Western and the direct owner of the Issuer, evidencing the net proceeds from the sale of the old notes that were loaned by the Issuer to Thunder Basin and, in turn, to us to repay our existing bank debt and for general purposes.

Arch Coal, Inc.

      Arch Coal is the second largest and one of the most productive operators of compliance and low sulfur coal mines in the United States. Including our operations, as of March 31, 2003, Arch Coal controlled approximately 2.9 billion tons of proven and probable coal reserves. As of March 31, 2003, Arch Coal had 25 operating mines. Arch Coal sold 106.7 million tons of coal in 2002 and 22.7 million tons of coal during the three months ended March 31, 2003.

      In addition to our operations, Arch Coal produces coal in Central Appalachia in the eastern United States. Arch Coal produces compliance and low sulfur coal exclusively, and 90% of its reserves are compliance quality or low sulfur. Arch Coal supplied the fuel for approximately 6% of the electricity used in the United States in 2002. In the past five years, Arch Coal has increased its coal production from 36.7 million tons in 1997 to 99.6 million tons in 2002, primarily as a result of selective acquisitions as well as the strategic development of existing reserves.

      Arch Coal’s common stock is listed on the New York Stock Exchange and traded under the symbol “ACI.”

The Exchange Offer

      On June 25, 2003, the Issuer issued in a private offering $700.0 million in aggregate principal amount of its 6 3/4% Senior Notes due 2013, which are referred to in this prospectus as the old notes. The Issuer, Arch Coal, Arch Western and the subsidiary guarantors entered into a registration rights agreement with the initial purchasers of the old notes in which the Issuer, Arch Coal, Arch Western and the subsidiary guarantors agreed to deliver this prospectus to you. You are entitled to exchange your old notes in the exchange offer for registered notes that are identical in all material respects to the old notes, except that the registered notes have been registered under the Securities Act of 1933, as amended, and will not bear legends restricting their transfer. Unless you are a broker-dealer or are unable to participate in the exchange offer, we believe that the registered notes to be issued in the exchange offer may be resold by you without compliance with the registration and prospectus delivery requirements of the Securities Act. You should read the discussions under the headings “The Exchange Offer” and “Description of the Registered Notes” for further information regarding the registered notes.

 
Registration Rights Agreement You are entitled under the registration rights agreement to exchange your old notes for registered notes with substantially identical terms. The exchange offer is intended to satisfy these exchange rights. After the exchange offer is complete, except as set forth in the next paragraph, you will no longer be entitled to any exchange or registration rights with respect to your old notes.
 
The registration rights agreement requires us to file a registration statement for a continuous offering in accordance with Rule 415 under the Securities Act for your benefit if:
 
• we determine that we are not permitted to effect the exchange offer due to any change in law or applicable interpretations of the SEC’s staff;
 
• the exchange offer is not consummated within 225 of the issuance date of the old notes;
 
• any initial purchaser of old notes so requests with respect to old notes that are not eligible to be exchanged in the exchange offer and that are held by it following consummation of the exchange offer;

2


Table of Contents

 
• any holder of old notes (other than an initial purchaser) is not eligible to participate in the exchange offer; or
 
• an initial purchaser of old notes does not receive freely tradeable registered notes in the exchange offer in exchange for old notes constituting any portion of an unsold allotment.
 
The Exchange Offer The Issuer is offering to exchange $1,000 principal amount of its 6 3/4% Senior Notes due 2013, which have been registered under the Securities Act and which we refer to in this prospectus as the registered notes, for each $1,000 principal amount of its unregistered 6 3/4% Senior Notes due 2013, which we refer to in this prospectus as the old notes. In order to be exchanged, an old note must be properly tendered and accepted. All old notes that are validly tendered and not validly withdrawn will be exchanged. As of the date of this prospectus, there are $700.0 million aggregate principal amount of old notes outstanding. The Issuer will issue the registered notes promptly after the expiration of the exchange offer.
 
Resales of the Registered Notes We believe that the registered notes to be issued in the exchange offer may be offered for resale, resold and otherwise transferred by you without compliance with the registration and prospectus delivery provisions of the Securities Act if you meet the following conditions:
 
• the registered notes are acquired by you in the ordinary course of your business;
 
• you are not engaging in and do not intend to engage in a distribution of the registered notes;
 
• you do not have an arrangement or understanding with any person to participate in the distribution of the registered notes; and
 
• you are not an affiliate of ours, as that term is defined in Rule 405 under the Securities Act.
 
Our belief is based on interpretations by the staff of the Securities and Exchange Commission, as set forth in no-action letters issued to third parties unrelated to us. The staff has not considered this exchange offer in the context of a no-action letter, and we cannot assure you that the staff would make a similar determination with respect to this exchange offer.
 
If you do not meet the above conditions, you may incur liability under the Securities Act if you transfer any registered note without delivering a prospectus meeting the requirements of the Securities Act. We do not assume or indemnify you against that liability.
 
Each broker-dealer that is issued registered notes in the exchange offer for its own account in exchange for old notes which were acquired by that broker-dealer as a result of market-making activities or other trading activities must agree to deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of the registered notes. A broker-

3


Table of Contents

dealer may use this prospectus for an offer to resell or to otherwise transfer these registered notes.
 
Expiration Date The exchange offer will expire at 5:00 p.m., New York City time, on                     , 2003, or such later date and time to which we extend it. We currently do not intend to extend the expiration date, although we reserve the right to do so. See “The Exchange Offer — Expiration Date; Amendments.”
 
Certain Conditions to the
Exchange Offer
The exchange offer is subject to certain customary conditions, which we may waive. Please read carefully the section of this prospectus captioned “The Exchange Offer — Conditions” for more information regarding the conditions to the exchange offer.
 
Procedures for Tendering Old Notes in the Form of Book-Entry Interests The old notes were issued as global securities in fully registered form without coupons. Beneficial interests in the old notes which are held by direct or indirect participants in The Depository Trust Company through certificateless depositary interests are shown on, and transfers of the old notes can be made only through, records maintained in book-entry form by DTC with respect to its participants.
 
If you are a holder of an old note held in the form of a book-entry interest and you wish to tender your old note for exchange pursuant to the exchange offer, you must transmit to The Bank of New York, as exchange agent, on or prior to the expiration of the exchange offer either:
 
• a written or facsimile copy of a properly completed and executed letter of transmittal and all other required documents to the address set forth on the cover page of the letter of transmittal; or
 
• a computer-generated message transmitted by means of DTC’s Automated Tender Offer Program system and forming a part of a confirmation of book-entry transfer in which you acknowledge and agree to be bound by the terms of the letter of transmittal.
 
The exchange agent must also receive on or prior to the expiration of the exchange offer either:
 
• a timely confirmation of book-entry transfer of your old notes into the exchange agent’s account at DTC, in accordance with the procedure for book-entry transfers described in this prospectus under the heading “The Exchange Offer — Book-Entry Transfer;” or
 
• the documents necessary for compliance with the guaranteed delivery procedures described below.
 
A letter of transmittal accompanies this prospectus. By executing the letter of transmittal or delivering a computer-generated message through DTC’s Automated Tender Offer Program system, you will represent to us that, among other things:

Table of Contents

 
• the registered notes to be acquired by you in the exchange offer are being acquired in the ordinary course of your business;
 
• you are not engaging in and do not intend to engage in a distribution of the registered notes;
 
• you do not have an arrangement or understanding with any person to participate in the distribution of the registered notes; and
 
• you are not an affiliate of ours.
 
Procedures for Tendering
Certificated Old Notes
If you are a holder of book-entry interests in the old notes, you are entitled to receive, in limited circumstances, in exchange for your book- entry interests, certificated notes which are in equal principal amounts to your book-entry interests. See “Description of the Registered Notes — Book-Entry System.” No certificated notes are issued and outstanding as of the date of this prospectus. If you acquire certificated old notes prior to the expiration of the exchange offer, you must tender your certificated old notes in accordance with the procedures described in this prospectus under the heading “The Exchange Offer — Procedures for Tendering — Certificated Old Notes.”
 
Special Procedures for
Beneficial Owners
If you are a beneficial owner of old notes that are registered in the name of a broker, dealer, commercial bank, trust company or other nominee, and you wish to tender the old notes in the exchange offer, you should contact that registered holder promptly and instruct that registered holder to tender on your behalf. If you wish to tender on your own behalf, you must, prior to completing and executing the letter of transmittal and delivering your old notes, either make appropriate arrangements to register ownership of the old notes in your name or obtain a properly completed bond power from the registered holder. The transfer of registered ownership may take considerable time and may not be able to be completed prior to the expiration date. See “The Exchange Offer — Procedures Applicable to All Holders.”
 
Guaranteed Delivery Procedures If you wish to tender your old notes and your old notes are not immediately available or you cannot deliver your old notes, the letter of transmittal or any other documents required by the letter of transmittal or comply with the applicable procedures under DTC’s Automated Tender Offer Program prior to the expiration date, you must tender your old notes according to the guaranteed delivery procedures set forth in this prospectus under “The Exchange Offer — Guaranteed Delivery Procedures.”
 
Acceptance of Old Notes and
Delivery of Registered Notes
Except under the circumstances described above under “Certain Conditions to the Exchange Offer,” we will accept for exchange any and all old notes which are properly tendered in the exchange offer prior to 5:00 p.m., New York City time, on the

expiration date. The registered notes will be delivered promptly following the expiration date. See “The Exchange Offer — Terms of the Exchange Offer.”
 
Withdrawal You may withdraw the tender of your old notes at any time prior to 5:00 p.m., New York City time, on the expiration date. The registered notes to be issued to you in the exchange offer will be delivered promptly following the expiration date. See “The Exchange Offer — Terms of the Exchange Offer.”
 
Exchange Agent The Bank of New York is serving as exchange agent in connection with the exchange offer. See “The Exchange Offer — Exchange Agent.”
 
Consequences of Failure to
Exchange
If you do not participate in the exchange offer, the liquidity of the market for your old notes could be adversely affected. See “The Exchange Offer — Consequences of Failure to Exchange.”
 
Important Federal Income Tax Considerations The exchange of the old notes for the registered notes should not be a taxable event for federal income tax purposes. See “Important Federal Income Tax Considerations.”

RISK FACTORS

      In addition to the other information contained in or incorporated by reference into this prospectus, you should carefully consider the following risk factors and the information under “Forward-Looking Statements,” which appears elsewhere in this prospectus, before deciding whether to participate in the exchange offer. The risk factors set forth below generally are applicable to the old notes as well as the registered notes.

Risks Relating to the Exchange Offer

 
If you fail to exchange your old notes, they will continue to be restricted securities and may become less liquid.

      Old notes which you do not tender or we do not accept will, following the exchange offer, continue to be restricted securities. You may not offer or sell untendered old notes except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. We will issue registered notes in exchange for the old notes pursuant to the exchange offer only following the satisfaction of procedures and conditions described elsewhere in this prospectus. These procedures and conditions include timely receipt by the exchange agent of the old notes and a properly completed and duly executed letter of transmittal.

      Because we anticipate that most holders of old notes will elect to exchange their old notes, we expect that the liquidity of the market for any old notes remaining after the completion of the exchange offer may be substantially limited. Any old note tendered and exchanged in the exchange offer will reduce the aggregate principal amount of the old notes outstanding. Following the exchange offer, untendered old notes generally will not have any further associated registration rights, and untendered old notes will continue to be subject to transfer restrictions. Accordingly, the liquidity of the market for any old notes could be adversely affected.

 
There may be no active trading market for the registered notes to be issued in the exchange offer.

      The registered notes are a new issue of securities for which there is no established market. We cannot assure you with respect to:

  the liquidity of any market for the registered notes that may develop;
 
  your ability to sell registered notes; or
 
  the price at which you will be able to sell registered notes.

      If a public market were to exist, the registered notes could trade at prices that may be higher or lower than their principal amount or purchase price, depending on many factors, including prevailing interest rates, the market for similar notes and our financial performance. We do not intend to list the registered notes to be issued to you in the exchange offer on any securities exchange or to seek approval for quotations through any automated quotation system. No active market for the registered notes is currently anticipated.

Risks Relating to Our Business

 
The demand for and pricing of our coal is greatly influenced by consumption patterns of the domestic electric generation industry, and any reduction in the demand for our coal by this industry may cause our profitability to decline.

      Demand for our coal and the prices that we may obtain for our coal are closely linked to coal consumption patterns of the domestic electric generation industry, which has accounted for approximately 92% of domestic coal consumption in recent years. These coal consumption patterns are influenced by factors beyond our control, including the demand for electricity, which is significantly dependent upon general economic conditions, summer and winter temperatures in the United States, government regulation, technological developments and the location, availability, quality and price of competing sources

Table of Contents

of coal, alternative fuels such as natural gas, oil and nuclear and alternative energy sources such as hydroelectric power. Demand for our low sulfur coal and the prices that we will be able to obtain for it will also be affected by the price and availability of high sulfur coal, which can be marketed in tandem with emissions allowances in order to meet Clean Air Act requirements. Any reduction in the demand for our coal by the domestic electric generation industry would result in a decline in our revenues and profit, which could be material.
 
We have experienced a net loss for the three months ended March 31, 2003 and may incur losses in the future.

      We incurred a net loss of $10.2 million for the three months ended March 31, 2003. We have experienced adverse pricing trends, oversupply in our coal markets and may face regulatory or judicial developments or other industry conditions that are beyond our control. These factors may affect our ability to mine and sell coal profitably.

 
Extensive environmental laws and regulations affect the end-users of coal and could reduce the demand for coal as a fuel source and cause the volume of our sales to decline.

      The Clean Air Act and similar state and local laws extensively regulate the amount of sulfur dioxide, particulate matter, nitrogen oxides, and other compounds emitted into the air from electric power plants, which are the largest end-users of our coal. Such regulations, which can take a variety of forms, may reduce demand for coal as a fuel source because they may require significant emissions control expenditures for coal-fired power plants to attain applicable ambient air quality standards, which may lead these generators to switch to other fuels that generate less of these emissions and may also reduce future demand for the construction of coal-fired power plants.

      The U.S. Department of Justice, on behalf of the EPA, has filed lawsuits against several investor-owned electric utilities and brought an administrative action against one government-owned utility for alleged violations of the Clean Air Act. We supply coal to some of the currently-affected utilities, and it is possible that other of our customers will be sued. These lawsuits could require the utilities to pay penalties, install pollution control equipment or undertake other emission reduction measures, any of which could adversely impact their demand for our coal.

      A regional haze program initiated by the EPA to protect and to improve visibility at and around national parks, national wilderness areas and international parks restricts the construction of new coal-fired power plants whose operation may impair visibility at and around federally protected areas and may require some existing coal-fired power plants to install additional control measures designed to limit haze-causing emissions.

      The Clean Air Act also imposes standards on sources of hazardous air pollutants. Although these standards have not yet been extended to coal mining operations, the EPA has announced that it would regulate hazardous air pollutants from coal-fired power plants. Under the Clean Air Act, coal-fired power plants will be required to control hazardous air pollution emissions by no later than 2009, which likely will require significant new investment in controls by power plant operators. These standards and future standards could have the effect of decreasing demand for coal.

      Other proposed initiatives, such as the Bush administration’s announced Clear Skies Initiative, may also have an effect upon coal operations. As proposed, this initiative is designed to further reduce emissions of sulfur dioxide, nitrogen oxides and mercury from power plants. Other so-called multi-pollutant bills, which could regulate additional air pollutants, have been proposed by various members of Congress. If such initiatives are enacted into law, power plant operators could choose other fuel sources to meet their requirements, reducing the demand for coal.

Because our industry is highly regulated, our ability to conduct mining operations is restricted and our profitability may decline.

      The coal mining industry is subject to regulation by federal, state and local authorities on matters such as:

  •  the discharge of materials into the environment;
 
  •  employee health and safety;
 
  •  mine permits and other licensing requirements;
 
  •  reclamation and restoration of mining properties after mining is completed;
 
  •  management of materials generated by mining operations;
 
  •  surface subsidence from underground mining;
 
  •  water pollution;
 
  •  legislatively mandated benefits for current and retired coal miners;
 
  •  air quality standards;
 
  •  protection of wetlands;
 
  •  endangered plant and wildlife protection;
 
  •  limitations on land use;
 
  •  storage of petroleum products and substances that are regarded as hazardous under applicable laws; and
 
  •  management of electrical equipment containing polychlorinated biphenyls, or PCBs.

      Extensive regulation of these matters has had and will continue to have a significant effect on our costs of production and competitive position. Further regulations, legislation or orders may also cause our sales or profitability to decline by hindering our ability to continue our mining operations, by increasing our costs or by causing coal to become a less attractive fuel source.

      Mining companies must obtain numerous permits that strictly regulate environmental and health and safety matters in connection with coal mining, some of which have significant bonding requirements. Regulatory authorities exercise considerable discretion in the timing of permit issuance. Also, private individuals and the public at large possess rights to comment on and otherwise engage in the permitting process, including through intervention in the courts. Accordingly, the permits we need for our mining operations may not be issued, or, if issued, may not be issued in a timely fashion, or may involve requirements that may be changed or interpreted in a manner which restricts our ability to conduct our mining operations or to do so profitably. Under the federal Clean Water Act, state regulatory authorities must conduct an antidegradation review before approving permits for the discharge of pollutants into waters that have been designated by the state as high quality. This review involves public and intergovernmental scrutiny of permits and requires permittees to demonstrate that the proposed activities are justified in order to accommodate significant economic or social development in the area where the waters are located. If the plaintiffs are successful, the exemption from the antidegradation review policy is revoked and we discharge into waters designated as high quality by the state, the cost, time and difficulty associated with obtaining and complying with Clean Water Act permits for our affected surface mining operations would increase and may hinder our ability to conduct such operations profitably.

      Federal and state laws require us to obtain surety bonds to secure payment of certain long-term obligations, including mine closure or reclamation costs, federal and state workers’ compensation costs, coal leases and other miscellaneous obligations. Many of these bonds are renewable on a yearly basis. It has become increasingly difficult for us to secure new surety bonds or renew such bonds without the

11


Table of Contents

posting of collateral. In addition, surety bond costs have increased while the market terms of such bonds have generally become more unfavorable.
 
Our profitability may fluctuate due to unanticipated mine operating conditions and other factors that are not within our control.

      Our mining operations are inherently subject to changing conditions that can affect levels of production and production costs at particular mines for varying lengths of time and can result in decreases in our profitability. Weather conditions, equipment replacement or repair, fuel prices, fires, variations in thickness of the layer, or seam, of coal, amounts of overburden, rock and other natural materials and other geological conditions have had, and can be expected in the future to have, a significant impact on our operating results. Prolonged disruption of production at any of our principal mines, particularly our Black Thunder mine, would result in a decrease in our revenues and profitability, which could be material. Other factors affecting the production and sale of our coal that could result in decreases in our profitability include:

  •  expiration or termination of, or sales price redeterminations or suspension of deliveries under, coal supply agreements;
 
  •  disruption or increases in the cost of transportation services;
 
  •  changes in laws or regulations, including permitting requirements;
 
  •  litigation;
 
  •  work stoppages or other labor difficulties;
 
  •  mine worker vacation schedules and related maintenance activities; and
 
  •  changes in coal market and general economic conditions.

      Decreases in our profitability as a result of the factors described above could adversely impact our quarterly or annual results materially.

 
Intense competition and excess industry capacity in the coal producing regions in which we operate has adversely affected our revenues and profitability and may continue to do so in the future.

      The coal industry is intensely competitive, primarily as a result of the existence of numerous producers in the coal producing regions in which we operate. A number of our competitors have greater financial resources than we do. We compete with four major coal producers, including Triton, in the Powder River Basin and effectively compete with a large number of coal producers in the markets that we serve. Additionally, we are subject to the continuing risk of reduced profitability as a result of excess industry capacity and weak power demand by the industrial sector of the economy, which led us to reduce the rate of coal production from planned levels and adversely impacted our profitability.

 
Deregulation of the electric utility industry may cause our customers to be more price-sensitive in purchasing coal, which could cause our profitability to decline.

      Electric utility deregulation is expected to provide incentives to generators of electricity to minimize their fuel costs and is believed to have caused electric generators to be more aggressive in negotiating prices with coal suppliers. To the extent utility deregulation causes our customers to be more cost sensitive, deregulation may have a negative effect on our profitability.

 
Our profitability may be adversely affected by the status of our long-term coal supply contracts.

      We sell a substantial portion of our coal under long-term coal supply agreements, which are contracts with a term greater than 12 months. The prices for coal shipped under these contracts may be below the current market price for similar-type coal at any given time. As a consequence of the substantial volume of our sales that are subject to these long-term agreements, we have less coal available with which to

12


Table of Contents

capitalize on higher coal prices if and when they arise. In addition, because long-term contracts typically allow the customer to elect volume flexibility, our ability to realize the higher prices that may be available in the spot market may be restricted when customers elect to purchase higher volumes under such contracts. Our exposure to market-based pricing may also be increased should customers elect to purchase fewer tons. In addition, the increasingly short terms of sales contracts and the consequent absence of price adjustment provisions in such contracts make it more likely that we will not be able to recover inflation related increases in mining costs during the contract term.
 
The loss of, or significant reduction in, purchases by our largest customers could adversely affect our revenues.

      For the year ended December 31, 2002, we derived 20.8% of our total coal revenues from sales to our two largest customers. At December 31, 2002, we had five coal supply agreements with those two customers that expire at various times from 2003 to 2004. We intend to discuss the extension of existing agreements or entering into new long-term agreements with those and other customers, but the negotiations may not be successful, and those customers may not continue to purchase coal from us under long-term coal supply agreements, or at all. If either of those customers were to significantly reduce their purchases of coal from us, or if we were unable to sell coal to them on terms as favorable to us as the terms under our current agreements, our revenues and profitability could suffer materially.

 
Because our profitability is substantially dependent on the availability of an adequate supply of coal reserves that can be mined at competitive costs, the unavailability of these types of reserves would cause our profitability to decline.

      Our profitability depends substantially on our ability to mine coal reserves that have the geological characteristics that enable them to be mined at competitive costs. Replacement reserves may not be available when required or, if available, may not be capable of being mined at costs comparable to those characteristic of the depleting mines. We may not be able to accurately assess the geological characteristics of any reserves that we acquire, which may adversely affect our profitability and financial condition. Exhaustion of reserves at particular mines also may have an adverse effect on our operating results that is disproportionate to the percentage of overall production represented by such mines.

 
Disruption in, or increased costs of, transportation services could adversely affect our profitability.

      The coal industry depends on rail and trucking transportation to deliver shipments of coal to customers, and transportation costs are a significant component of the total cost of supplying coal. Disruptions of these transportation services could temporarily impair our ability to supply coal to our customers and thus adversely affect our business and the results of our operations. In addition, increases in transportation costs associated with our coal, or increases in our transportation costs relative to transportation costs for coal produced by our competitors or of other fuels, could adversely affect our business and profitability.

 
We face numerous uncertainties in estimating our economically recoverable coal reserves, and inaccuracies in our estimates could result in lower than expected revenues, higher than expected costs or decreased profitability.

      We base our reserve information on geological data assembled and analyzed by our staff, which includes various engineers and geologists, and periodically reviewed by outside firms. The reserve estimates are annually updated to reflect production of coal from the reserves and new drilling or other data received. There are numerous uncertainties inherent in estimating quantities of recoverable reserves, including many factors beyond our control. Estimates of economically recoverable coal reserves and net cash flows necessarily depend upon a number of variable factors and assumptions, such as geological and mining conditions which may not be fully identified by available exploration data or which may differ from experience in current operations, historical production from the area compared with production from other producing areas, the assumed effects of regulation by governmental agencies and assumptions concerning

13


Table of Contents

coal prices, operating costs, severance and excise tax, development costs and reclamation costs, all of which may vary considerably from actual results.

      For these reasons, estimates of the economically recoverable quantities attributable to any particular group of properties, classifications of reserves based on risk of recovery and estimates of net cash flows expected from particular reserves prepared by different engineers or by the same engineers at different times may vary substantially. Actual coal tonnage recovered from identified reserve areas or properties and revenues and expenditures with respect to our reserves may vary materially from estimates. These estimates thus may not accurately reflect our actual reserves.

 
Defects in title or loss of any leasehold interests in our properties could limit our ability to mine these properties or result in significant unanticipated costs.

      We conduct a significant part of our mining operations on properties that we lease. The loss of any lease could adversely affect our ability to mine the associated reserves. Because title to most of our leased properties and mineral rights is not usually verified until we make a commitment to develop a property, which may not occur until after we have obtained necessary permits and completed exploration of the property, our right to mine some of our reserves has in the past, and may again in the future, be adversely affected if defects in title or boundaries exist. In order to obtain leases or mining contracts to conduct our mining operations on property where these defects exist, we have had to, and may in the future have to, incur unanticipated costs. In addition, we may not be able to successfully negotiate new leases or mining contracts for properties containing additional reserves, or maintain our leasehold interests in properties where we have not commenced mining operations during the term of the lease.

 
Acquisitions that we may undertake would involve a number of inherent risks, any of which could cause us not to realize the benefits anticipated to result.

      We continually seek to expand our operations and coal reserves through acquisitions of businesses and assets. Acquisition transactions involve various inherent risks, such as:

  •  uncertainties in assessing the value, strengths, weaknesses, contingent and other liabilities and potential profitability of acquisition or other transaction candidates;
 
  •  the potential loss of key personnel of an acquired business;
 
  •  the ability to achieve identified operating and financial synergies anticipated to result from an acquisition or other transaction;
 
  •  problems that could arise from the integration of the acquired business; and
 
  •  unanticipated changes in business, industry or general economic conditions that affect the assumptions underlying the acquisition or other transaction rationale.

Any one or more of these factors could cause us not to realize the benefits anticipated to result from the acquisition of businesses or assets.

 
Changes in our credit ratings could adversely affect our costs and expenses.

      Any downgrade in our credit ratings could adversely affect our ability to borrow and result in more restrictive borrowing terms, including increased borrowing costs, more restrictive covenants and the extension of less open credit. This in turn could affect our internal cost of capital estimates and therefore operational decisions.

 
Agreements to which we are a party contain limitations on our ability to manage our operations exclusively.

      The agreement under which we were formed provides that one of Arch Coal’s affiliates, as our managing member, generally has exclusive power and authority to conduct, manage and control our

14


Table of Contents

business. However, consent of our other member generally would be required in the event that we would propose to make a distribution, incur indebtedness, sell properties or merge or consolidate with any other entity if, at that time, we have a debt rating less favorable than Ba3 from Moody’s Investors Service or BB-from Standard & Poor’s or fail to meet specified indebtedness and interest coverage ratios.

      In connection with our formation, Arch Coal entered into an agreement under which Arch Coal agreed to indemnify our other member against specified tax liabilities in the event that these liabilities arise as a result of certain actions taken prior to June 1, 2013, including the sale or other disposition of specified properties of ours, repurchases by us of our equity interests or the reduction under some circumstances of indebtedness incurred by us in connection with our acquisition.

      The membership interests in Canyon Fuel, which operates three coal mines in Utah, are owned 65% by us and 35% by a subsidiary of ITOCHU Corporation of Japan. The agreement which governs the management and operations of Canyon Fuel provides for a management board to manage its business and affairs. Some major business decisions concerning Canyon Fuel require the vote of 70% of the membership interests and therefore limit our ability to make these decisions unilaterally. These decisions include:

  •  admission of additional members; approval of annual business plans;
 
  •  the making of significant capital expenditures;
 
  •  sales of coal below specified prices;
 
  •  agreements between Canyon Fuel and any member;
 
  •  institution or settlement of litigation;
 
  •  a material change in the nature of Canyon Fuel’s business or a material acquisition;
 
  •  the sale or other disposition, including by merger, of assets other than in the ordinary course of business;
 
  •  incurrence of indebtedness;
 
  •  entering into leases; and
 
  •  the selection and removal of officers.

The Canyon Fuel agreement also contains restrictions on the transfer of our membership interest in Canyon Fuel and a buy/sell provision, which can be utilized by either member in the event of a deadlock in certain management decisions.

 
Our expenditures for postretirement medical and pension benefits are expected to be significantly higher in 2003 and could further increase in the future.

      We estimate our future postretirement medical and pension benefit obligations based on various assumptions, including:

  •  actuarial estimates;
 
  •  assumed discount rates;
 
  •  estimates of mine lives;
 
  •  expected returns on pension plan assets; and
 
  •  changes in health care costs.

Based on changes in our assumptions, we expect that our annual postretirement health and pension benefit costs will increase by approximately $1.9 million in 2003. If our assumptions relating to these benefits change in the future, our costs could further increase, which would reduce our profitability. In addition, future regulatory and accounting changes relating to these benefits could result in increased obligations or additional costs, which could also have a material adverse affect on our financial results.

Additional Risks Relating to Arch Coal’s Business

      In addition to the risks described above, which relate to Arch Coal’s operations as a whole, Arch Coal also is subject to the following additional risks relating to its eastern operations.

 
Mining in Central Appalachia is more complex and involves more regulatory constraints than mining in the regions in which we operate.

      The geological characteristics of Central Appalachia coal reserves, such as depth of overburden and coal seam thickness, make them complex and costly to mine. As mines become depleted, replacement reserves may not be available when required or, if available, may not be capable of being mined at costs comparable to those characteristic of the depleting mines. In addition, as compared to mines in the Powder River Basin, permitting and licensing and other environmental and regulatory requirements are more costly and time-consuming to satisfy. These factors could materially adversely affect the mining operations and cost structures of, and customers’ ability to use coal produced by, operators in Central Appalachia, including Arch Coal.

 
Arch Coal has experienced net losses in recent periods, which may continue or reoccur in the future.

      Arch Coal reported a net loss of $2.6 million on a consolidated basis for the year ended December 31, 2002 and a net loss available to common shareholders of $18.0 million on a consolidated basis for the three months ended March 31, 2003 and has incurred losses in prior periods. These recent losses are primarily attributable to Arch Coal’s decision to reduce coal production in response to a weak pricing environment stemming from oversupply in our coal markets as a result of the general economic downturn that reduced electricity demand in the United States. Due to the continuing possibility of adverse pricing trends, regulatory and judicial developments, or other industry conditions that are beyond Arch Coal’s control and that affect Arch Coal’s ability to mine and sell coal profitably, Arch Coal may incur losses in the future.

 
The loss of, or significant reduction in, purchases by Arch Coal’s largest customers could adversely affect Arch Coal’s revenues.

      For the year ended December 31, 2002, Arch Coal derived 61% of its total coal revenues from sales to its ten largest customers. At December 31, 2002, Arch Coal had 16 coal supply agreements with these customers that expire at various times from 2003 to 2012. Arch Coal intends to discuss the extension of existing agreements or entering into new long-term agreements with some of these customers, but these negotiations may not be successful, and those customers may not continue to purchase coal from Arch Coal under long-term coal supply agreements, or at all. If a number of these customers were to significantly reduce their purchases of coal from Arch Coal, or if Arch Coal was unable to sell coal to them on terms as favorable to Arch Coal as the terms of its current agreements, Arch Coal’s financial condition and results of operations could suffer materially.

 
Arch Coal and Vulcan may be unable to obtain the regulatory approvals required to complete the acquisition or, in order to do so, Arch Coal may be required to comply with material restrictions or conditions.

      The acquisition is subject to review by the U.S. Federal Trade Commission under the Hart-Scott-Rodino Improvements Act of 1976. Under that statute, Arch Coal and Vulcan were required to make notification filings, and Arch Coal and Vulcan are awaiting the expiration or early termination of statutory waiting periods prior to completing the acquisition. Arch Coal and Vulcan have not yet obtained any of the governmental or regulatory approvals required to compete the acquisition.

      The reviewing authorities may not permit the acquisition at all or may impose restrictions or conditions on the acquisition. These conditions could include a complete or partial divestiture or the holding separate of assets or businesses. Arch Coal may refuse to complete the acquisition if restrictions or

16


Table of Contents

conditions are required by governmental authorities that would materially adversely impact the benefits anticipated to be derived as a result of the acquisition.

      In addition, during or after the statutory waiting periods, and even after completion of the acquisition, governmental authorities could seek to block or challenge the acquisition as they deem necessary or desirable in the public interest. In some jurisdictions, a competitor, customer or other third party could initiate a private action under the antitrust laws challenging or seeking to enjoin the acquisition, before or after it is completed. Arch Coal or Vulcan may not prevail or may incur significant costs in defending or settling any action under antitrust laws.

 
Although Arch Coal expects that its planned acquisition of Vulcan will result in benefits to Arch Coal, it may not realize those benefits because of potential challenges to integration.

      The failure of Arch Coal to meet the challenges involved in integrating its operations with those of Vulcan successfully or otherwise to realize any of the anticipated benefits of the acquisition could materially impact the results of operations of Arch Coal. Realizing the potential benefits of the acquisition will depend in part on the successful integration of operations and personnel. Arch Coal may not successfully integrate Vulcan’s operations with its operations in a timely manner, or at all, and Arch Coal may not realize the anticipated benefits or synergies of the acquisition to the extent, or in the timeframe, anticipated. These anticipated benefits and synergies are based on projections and assumptions.

 
Changes in Arch Coal’s credit ratings could adversely affect its costs and expenses.

      Any downgrade in the credit ratings of Arch Coal could adversely affect the ability of Arch Coal to borrow and result in more restrictive borrowing terms, including increased borrowing costs, more restrictive covenants and the extension of less open credit. This in turn could affect Arch Coal’s internal cost of capital estimates and therefore operational decisions.

 
Acquisitions that Arch Coal may undertake involve a number of inherent risks, any of which could cause Arch Coal not to realize the benefits anticipated to result.

      Arch Coal continually seeks to expand its operations and coal reserves in the regions in which it operates through acquisitions of businesses and assets. Acquisition transactions involve various inherent risks, such as:

  •  difficulties in assessing the value, strengths, weaknesses, contingent and other liabilities and potential profitability of acquisition or other transaction candidates;
 
  •  the potential loss of key personnel of an acquired business;
 
  •  the ability to achieve identified operating and financial synergies anticipated to result from an acquisition or other transaction;
 
  •  problems that could arise from the integration of the acquired business; and
 
  •  unanticipated changes in business, industry or general economic conditions that affect the assumptions underlying the acquisition or other transaction rationale.

Any one or more of these factors could cause Arch Coal not to realize the benefits anticipated to result from the acquisition of businesses or assets.

Risks Related to the Registered Notes

 
Both we and Arch Coal have a significant amount of debt relative to our equity capitalization, which limits our flexibility and imposes restrictions on us, and a downturn in economic or industry conditions may materially affect our ability to meet our future financial commitments and liquidity needs.

      As of March 31, 2003, after giving effect to the sale of the old notes and the application of the net proceeds therefrom, we would have had indebtedness of approximately $700.0 million, representing

17


Table of Contents

approximately 60% of our capital employed, and Arch Coal would have had consolidated indebtedness (including ours) of approximately $729.8 million (excluding $298.2 million of secured debt expected to be incurred by Arch Coal under its revolving credit facility to finance its acquisition of Vulcan), representing approximately 53% of its capital employed. Our ability to satisfy our debt, lease and royalty obligations, and our ability to refinance our indebtedness, will depend upon our future operating performance, which will be affected by prevailing economic conditions in the markets that we serve and financial, business and other factors, many of which are beyond our control. We may be unable to generate sufficient cash flow from operations and future borrowings or other financing may be unavailable in an amount sufficient to enable us to fund our future financial obligations or our other liquidity needs.

      The amount and terms of our debt could have material consequences to our business, including, but not limited to:

  •  making it more difficult for us to satisfy our debt covenants and debt service, lease payment and other obligations;
 
  •  increasing our vulnerability to general adverse economic and industry conditions;
 
  •  limiting our ability to obtain additional financing to fund future acquisitions, working capital, capital expenditures or other general operating requirements;
 
  •  reducing the availability of cash flow from operations to fund acquisitions, working capital, capital expenditures or other general operating purposes;
 
  •  limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we compete; and
 
  •  placing us at a competitive disadvantage when compared to competitors with less relative amounts of debt.

      Despite these significant levels of indebtedness, we and Arch Coal may incur additional indebtedness in the future, which would heighten the risks described above.

 
The Arch Coal promissory notes securing the registered notes are unsecured obligations of Arch Coal and are subordinated to Arch Coal’s secured indebtedness and to the indebtedness and other liabilities of Arch Coal’s subsidiaries other than us and our subsidiaries. If an event of default occurs, Arch Coal may not have sufficient funds to repay all or any of the promissory notes.

      The registered notes will be secured by a pledge of the promissory notes issued by Arch Coal to us evidencing cash loaned by us to Arch Coal. On March 31, 2003, there was $361.1 million outstanding under those promissory notes. Any distributions by us to, or investments by us in, Arch Coal or any of its subsidiaries, other than us or our subsidiaries, will be in the form of loans evidenced by additional promissory notes which will be pledged for the benefit of the holders of the registered notes as security for the payment of the registered notes. Under the indenture, we can distribute to Arch Coal all of our cash, other than amounts necessary to pay for our operating expenses, interest and principal obligations on indebtedness, capital expenditures, improvements and replacements, contingencies, reserves and other expenses. However, the aggregate principal amount of Arch Coal notes may not be equal to or greater than the aggregate principal amount of registered notes outstanding. In addition, because the Arch Coal notes are demand notes, Arch Coal may repay all or part of the Arch Coal notes prior to maturity of your registered notes, in which case, in the event of default, you may not have any claim, or you may have a more limited claim, against Arch Coal.

      Arch Coal is a holding company and does not directly conduct any business operations. Arch Coal depends on its operating subsidiaries and has no assets other than its interests in its subsidiaries. The Arch Coal notes are unsecured obligations of Arch Coal ranking effectively junior in right of payment to all existing and future secured debt of Arch Coal to the extent of the collateral securing such debt. As of March 31, 2003, Arch Coal had $25.0 million of secured debt, which does not include $298.2 million of secured debt that Arch Coal expects to incur to finance its acquisition of Vulcan. In addition, the Arch

18

Coal notes are structurally subordinate to the indebtedness and other liabilities of all of Arch Coal’s subsidiaries other than us and the guarantors. Therefore, all of the indebtedness and other liabilities, including trade payables, of those subsidiaries must be satisfied in full before any of the assets of such subsidiaries would be available for distribution, upon a liquidation or otherwise, to Arch Coal to meet its obligations with respect to the Arch Coal notes. As of March 31, 2003, the subsidiaries of Arch Coal (other than Arch Western and its subsidiaries) would have had $703.7 million of debt and other liabilities, excluding approximately $107.1 million of liabilities of Vulcan that would be assumed upon completion of the acquisition. As a result, Arch Coal may have insufficient assets or funds to repay the promissory notes in whole, in part or at all.

      Although the holders of the registered notes will have a first-priority security interest in the Arch Coal notes, we will be permitted to incur liens on the Arch Coal notes in favor of the lenders under a credit facility in an amount not to exceed $100.0 million, which liens will be equal and ratable with the liens securing the registered notes. As a result, in the event that we foreclose on the Arch Coal notes, we may have to share proceeds from such foreclosure with the lenders under such credit facility.

 
The guarantees will be structurally subordinate to the indebtedness of our subsidiaries that are not guarantors of the registered notes.

      You will not have any claim as a creditor against our subsidiaries that are not guarantors of the registered notes, which currently includes our 65% owned subsidiary, Canyon Fuel (which represented 2% and 12% of our revenue and assets, respectively, in 2002). As a result, all indebtedness and other liabilities, including trade payables, of the non-guarantor subsidiaries, whether secured or unsecured, must be satisfied before any of the assets of such subsidiaries would be available for distribution, upon a liquidation or otherwise, to us in order for us to meet our obligations with respect to the guarantees. As of March 31, 2003, Canyon Fuel had approximately $51.8 million of total indebtedness and other liabilities, including trade payables and accrued expenses. In addition to the structurally senior claims of creditors, the equity interests of our joint venture partner in any dividend or other distribution made by Canyon Fuel would need to be satisfied.

 
The guarantees will not be secured by any assets of the guarantors and therefore will be structurally subordinated to the guarantors’ existing and future secured indebtedness.

      The registered notes will be general unsecured obligations ranking effectively junior in right of payment to all existing and future secured debt of each guarantor to the extent of the collateral securing such debt. In addition, the indenture governing the registered notes will permit the incurrence of additional debt, some of which may be secured debt. In the event that a guarantor is declared bankrupt, becomes insolvent or is liquidated or reorganized, creditors whose debt is secured by assets of the guarantor will be entitled to the remedies available to secured holders under applicable laws, including the foreclosure of the collateral securing such debt, before any payment may be made with respect to the affected guarantees. Holders of the registered notes will participate ratably with all holders of the guarantors’ unsecured indebtedness that are deemed to be of the same class as the guarantees, and potentially with all other general creditors, based upon the respective amounts owed to each holder or creditor, in the guarantors’ remaining assets. In any of the foregoing events, there may be insufficient assets to pay amounts due on the registered notes. As a result, holders of the registered notes may receive less, ratably, than holders of secured indebtedness.

 
We may not generate cash flow sufficient to service all of our obligations, including our obligations related to the registered notes.

      Our ability to make payments on and to refinance our indebtedness, including our guarantees of the registered notes, depends on our ability to generate cash in the future. We are subject to general economic, climatic, industry, financial, competitive, legislative, regulatory and other factors that are beyond our control. In particular, economic conditions could cause the price of coal to fall, our revenue to decline and hamper our ability to repay our indebtedness, including the registered notes. As a result, we may need to

19


Table of Contents

refinance all or a portion of our indebtedness, including the registered notes, on or before maturity. Our ability to refinance debt or obtain additional financing will depend on, among other things:

  •  our financial condition at the time;
 
  •  restrictions in the indenture governing the registered notes and any other indebtedness; and
 
  •  other factors, including financial market or coal industry conditions.

As a result, we may not be able to refinance any of our indebtedness, including the registered notes, on commercially reasonable terms, or at all. If our operations do not generate sufficient cash flow from operations, and additional borrowings or refinancings are not available to us, we may not have sufficient cash to enable us to meet all of our obligations, including payments on the registered notes.

 
The terms of the agreements governing our indebtedness contain significant restrictions that limit our operating and financial flexibility.

      The indenture governing the registered notes will contain covenants that, among other things, limit our ability and the ability of our subsidiaries to:

  •  incur more debt;
 
  •  make distributions;
 
  •  make investments;
 
  •  create liens;
 
  •  issue and sell capital stock of subsidiaries;
 
  •  sell assets;
 
  •  enter into restrictions affecting the ability of restricted subsidiaries to make distributions, loans or advances to us;
 
  •  engage in transactions with affiliates;
 
  •  enter into sale and leasebacks; and
 
  •  merge or consolidate or transfer and sell assets.

These restrictions on operations and financings, as well as those that may be contained in future debt agreements, may limit our ability and the ability of Arch Coal to execute preferred business strategies. Moreover, if operating results fall below current levels, we may be unable to comply with these covenants. If that occurs, our lenders, including you, could accelerate their debt. If their debt is accelerated, we may not be able to repay all of their debt, in which case your registered notes may not be fully repaid, if they are repaid at all.

 
If the registered notes become rated investment grade by both Standard & Poor’s and Moody’s, certain covenants contained in the indenture will be terminated, and you will lose the protection of these covenants.

      The indenture contains certain covenants that will cease to be in effect from and after the first date when the registered notes are rated investment grade by both Standard & Poor’s and Moody’s. These covenants restrict, among other things, our ability and the ability of our subsidiaries to pay dividends, incur additional debt and enter into certain types of transactions. Because these restrictions will not apply when the registered notes are rated investment grade, we will be able to incur additional debt and consummate transactions that may impair our ability to satisfy our obligations with respect to our guarantee or the Issuer’s ability to satisfy its obligations with respect to the registered notes. These covenants will not be restored, even if the credit ratings assigned to the registered notes later fall below investment grade.

The Issuer may be unable to repurchase registered notes in the event of a change of control.

      Upon the occurrence of certain kinds of change of control events, you will have the right, as a holder of the registered notes, to require the Issuer to repurchase all of your registered notes at a repurchase price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to the date of repurchase. The Issuer may not be able to pay you the required price for your registered notes at that time because we or the Issuer may not have available funds to pay the repurchase price. In addition, the terms of other existing or future debt may prevent the Issuer from paying you.

 
Federal and state fraudulent conveyance laws may permit a court to void the registered notes and the guarantees, and, if that occurs, you may not receive any payments on the registered notes.

      The issuance of the registered notes and the guarantees may be subject to review under federal and state fraudulent conveyance statutes. While the relevant laws may vary from state to state, under such laws the payment of consideration generally will be a fraudulent conveyance if:

  •  it was paid with the intent of hindering, delaying or defrauding creditors; or
 
  •  the Issuer or any of the guarantors received less than fair consideration in return for issuing either the registered notes or a guarantee, as applicable, and either:

  •  the Issuer or the guarantor was insolvent or rendered insolvent by reason of the incurrence of the indebtedness;
 
  •  payment of the consideration left the Issuer or the guarantor with an unreasonably small amount of capital to carry on the business; or
 
  •  the Issuer or the guarantor intended to, or believed that it would, incur debts beyond its ability to pay the debt.

      If a court were to find that the issuance of the registered notes or a guarantee was a fraudulent conveyance, the court could void the payment obligations under the registered notes or such guarantee or further subordinate the registered notes or such guarantee to presently existing and future indebtedness, or require the holders of the registered notes to repay any amounts received with respect to the registered notes or such guarantee. In the event of a finding that a fraudulent conveyance occurred, you may not receive any repayment on the registered notes. Further, the voidance of the registered notes or a guarantee could result in an event of default with respect to our other debt that could result in acceleration of that debt.

 
There is currently no active trading market for the registered notes. If an active trading market does not develop for these registered notes, you may not be able to resell them.

      No active trading market currently exists for the registered notes, and none may develop. The registered notes will not be listed on any securities exchange. If an active trading market does not develop, you may not be able to resell your registered notes at their fair market value or at all. Historically, the market for non-investment grade debt has been subject to disruptions that have caused substantial volatility in the prices of securities similar to the notes. The market for the registered notes may be subject to similar disruptions. The trading price may depend upon prevailing interest rates, the market for similar securities and other factors, including general economic conditions and the financial condition, performance and prospects of Arch Western and Arch Coal. These factors could adversely affect you as a holder of registered notes.

FORWARD-LOOKING STATEMENTS

      You should carefully review the information contained in or incorporated by reference into this prospectus. In this prospectus, statements that are not reported financial results or other historical information are “forward-looking statements.” Forward-looking statements give current expectations or forecasts of future events and are not guarantees of future performance. They are based on our management’s expectations that involve a number of business risks and uncertainties, any of which could cause actual results to differ materially from those expressed in or implied by the forward-looking statements.

      You can identify these forward-looking statements by the fact that they do not relate strictly to historic or current facts. They use words such as “anticipate,” “estimate,” “project,” “intend,” “plan,” “believe” and other words and terms of similar meaning in connection with any discussion of future operating or financial performance. In particular, these include statements relating to:

  •  our expectation of continued growth in the demand for electricity;
 
  •  our belief that legislation and regulations relating to the Clean Air Act and the relatively higher costs of competing fuels will increase demand for our compliance and low sulfur coal;
 
  •  our expectation that we will continue to have adequate liquidity from cash flow from operations;
 
  •  a variety of market, operational, geologic, permitting, labor and weather related factors;
 
  •  expectations of Arch Coal regarding the consummation of the Triton acquisition and any synergies to be derived from the acquisition; and
 
  •  the other risks and uncertainties which are described in this prospectus under “Risk Factors.”

      We cannot guarantee that any forward-looking statements will be realized, although we believe that we have been prudent in our plans and assumptions. Achievement of future results is subject to risks, uncertainties and assumptions that may prove to be inaccurate. Should known or unknown risks or uncertainties materialize, or should underlying assumptions prove to be inaccurate, actual results could vary materially from those anticipated, estimated or projected. You should bear this in mind as you consider any forward-looking statements.

      We undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required by law. You are advised, however, to consider any additional disclosures that we or Arch Coal may make on related subjects in future filings with the SEC. You should understand that it is not possible to predict or identify all factors that could cause our actual results to differ. Consequently, you should not consider any such list to be a complete set of all potential risks or uncertainties.

USE OF PROCEEDS

      The Issuer will not receive any cash proceeds from the completion of the exchange offer.

Earnings consist of income (loss) from continuing operations before income taxes and are adjusted to include fixed charges (excluding capitalized interest). Fixed charges consist of interest incurred on indebtedness, the portion of operating lease rentals deemed representative of the interest factor and the amortization of debt expense. In 1998, fixed charges exceeded earnings by $5.0 million.

ARCH WESTERN MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

      The following discussion should be read in conjunction with our consolidated financial statements and notes thereto included elsewhere in this prospectus.

Overview

      We were formed as a joint venture on June 1, 1998 when Arch Coal acquired the U.S. coal operations of Atlantic Richfield Company and combined these operations with Arch Coal’s western operations. Our membership interests are owned 99% by Arch Coal and 1% by an affiliate of BP p.l.c., the successor to Atlantic Richfield Company.

      Excluding our Canyon Fuel joint venture, the results of which are accounted for under the equity method of accounting, we sold approximately 72.5 million tons of coal in 2002. We sold approximately 86% of this tonnage under long-term contracts, which are contracts of greater than one year, and the balance was sold on the spot market. We derived approximately 87% of our 2002 coal sales revenues from sales of coal under long-term contracts.

      Our mining operations are inherently subject to changing conditions that can affect levels of production and production costs at particular mines for varying lengths of time and result in fluctuations in our profitability. Weather conditions, equipment replacement or repair, fires, variations in coal seam thickness, amounts of overburden, rock and other natural materials and other geological conditions, have had, and can be expected in the future to have, a significant impact on our operating results. For example, we were forced to temporarily idle our West Elk mine in Colorado for more than five months during 2000 following the detection of combustion gases in a portion of the mine. The temporary closure of this mine adversely affected our operating results in 2000. A prolonged disruption of production at any of our principal mines, particularly our Black Thunder operation in Wyoming, would have a material adverse effect on us. Other factors affecting the production and sale of our coal that can result in fluctuations in our profitability include the following:

  •  expiration or termination of, or sales price redeterminations or suspension of deliveries under, coal supply agreements;
 
  •  disruption or increases in the cost of transportation services;
 
  •  changes in laws or regulation, including permitting requirements;
 
  •  litigation;
 
  •  work stoppages or other labor difficulties; and
 
  •  changes in coal market and general economic conditions.

      As our managing member, Arch Coal performs certain management and administrative functions on our behalf. Historically, we have paid selling, general and administrative services fees to Arch Coal. These fees were $2.3 million, $2.2 million, and $1.9 million for the years ended December 31, 2002, 2001 and 2000. These fees were not intended to represent the fair value of the services performed, nor did they approximate amounts that would be expected to be incurred if we were a stand-alone entity. In connection with the offering of the old notes, management of Arch Coal allocated additional expenses to us based on Arch Coal’s best estimates of proportional or incremental costs, whichever is more representative of costs incurred by Arch Coal on our behalf. We will not be required to make payments for these additional expenses and the amounts of these expenses have been reflected as a capital contribution to us from Arch

Coal. The additional amounts allocated are reflected in “selling, general and administrative expenses” in the accompanying consolidated financial statements and are summarized in the following table:

Results of Operations

 
Three Months Ended March 31, 2003 Compared with Three Months Ended March 31, 2002

      Results for the three months ended March 31, 2003 benefited from higher average coal sales realizations and from improved earnings from our investment in Canyon Fuel. These improvements were offset slightly by increased production costs, due primarily to the impact of severe weather during the quarter. Additionally, our reported results were negatively impacted by the cumulative effect of a loss resulting from the adoption of Statement of Financial Accounting Standards No. 143, Accounting for Asset Retirement Obligations (FAS 143).

      Operating results for the first quarter of 2003 versus the first quarter of 2002 and additional discussion of the results for the first quarter of 2003 are provided below.

      Coal sales. The increase in coal sales in the three months ended March 31, 2003 was primarily due to increased coal prices, offset by a reduction in the number of tons sold. We sold 15.8 million tons during the three months ended March 31, 2003 as compared to 16.2 million tons in the quarter ended March 31, 2002, a decline of 3.0%. Our average realized sales price improved from $6.77 per ton in the quarter ended March 31, 2002 to $7.18 per ton during the three months ended March 31, 2003. The increase in per ton coal sales realization was primarily due to higher contract prices.

      Income from equity investment. In the first quarter of 2003, income from our investment in Canyon Fuel increased due to improved operating performance at certain of Canyon Fuel’s mines as compared to the prior year’s period, where one mine experienced geologic issues that impacted 2002 performance.

      Cost of coal sales. Cost of coal sales remained flat in the three months ended March 31, 2003 as compared to the same period in 2002 despite lower production volumes. On a per ton sold basis, cost of coal sales was $6.72 for the three months ended March 31, 2003, as compared to $6.51 in the quarter ended March 31, 2002. The increase on a per ton basis is due to disruptions in production due to severe weather in March 2003 and increased diesel fuel costs.

      Selling, general and administrative expenses. Selling, general and administrative expenses represent our proportional share of costs allocated from Arch Coal. The cost increase from the first quarter 2003 compared to same period in 2002 is a result of additional legal, personnel and information services costs.

      Interest expense. Interest expense increased during the first quarter of 2003 as compared to the first quarter of 2002 as a result of an increase in our cost of borrowing. We completed a refinancing of our term loans in April 2002. The new loans contained higher credit spreads than the previous loan.

      Interest income primarily from Arch Coal. Our cash transactions are managed by Arch Coal. Cash paid to or from us that is not considered a distribution or a contribution is maintained as a receivable from Arch Coal. The receivable balance earns interest from Arch Coal at the prime interest rate. The increase in interest income primarily from Arch Coal is due to an increase in the amount of the receivable from Arch Coal from $283.5 million at March 31, 2002 to $361.1 million at March 31, 2003.

Cumulative Effect of Accounting Change

      Effective January 1, 2003, we adopted FAS 143, which requires legal obligations associated with the retirement of long-lived assets to be recognized at fair value at the time obligations are incurred. Upon initial recognition of a liability, that cost should be capitalized as part of the related long-lived asset and allocated to expense over the useful life of the asset. Application of FAS 143 resulted in a cumulative effect loss as of January 1, 2003 of $18.3 million.

 
Year Ended December 31, 2002, Compared to Year Ended December 31, 2001

      Our results for 2002 were adversely impacted by the state of oversupply in the coal market that resulted from an extremely mild winter and a period of industrial economic weakness that dampened electricity demand. As a result, we reduced our rate of production from planned levels at our mining operations. Offsetting the impact of the overall production cuts was an improvement in operating performance at our West Elk mine, which had experienced production difficulties and increased costs in 2001 resulting from high methane levels.

      Operating results for 2002 versus 2001 and additional discussion of the 2002 results are provided below.

      Coal sales. The increase in coal sales in 2002 was the result of higher average pricing on coal shipped during 2002 as compared to 2001. Average realizations on a per ton basis were $6.79 per ton in 2002 as compared to $6.35 per ton in 2001. This increase was due in part to higher contract prices and in part to the mix of the tons sold. In 2002, a higher percentage of tons sold were from our West Elk mine in Colorado. The average realized sales price from this mine is generally higher than prices from our other operations. Production at the West Elk mine was constrained in 2001 due to higher than normal levels of methane gas in the coal seam. Partially offsetting the impact of higher average prices was a decrease in the number of tons sold, from 73.7 million tons in 2001 to 72.5 million tons in 2002.

      Income from equity investment. The decrease in investment income from Canyon Fuel resulted from decreased operating earnings at Canyon Fuel due to the expiration of a favorable sales contract at the end of 2001, reduced operating results in early 2002 at one mine resulting from adverse geologic issues and a weak market environment for Utah coal throughout 2002. Additionally, in 2001, Canyon Fuel recognized recoveries of previously paid property taxes. Our share of these recoveries was $2.6 million.

      Other revenues. The decrease in other revenues is primarily due to gains on land sales in 2001 of $5.4 million. There were no significant land sales in 2002. Additionally, we recognized $2.1 million of outlease royalties in 2001 from an outlease arrangement that terminated in 2001.

      Cost of coal sales. The increase in cost of coal sales is due primarily to the change in sales mix noted above.

      In addition, the following items impacted cost of coal sales in the period noted:

  •  Year ended December 31, 2002

        We received a final insurance settlement of $9.4 million related to the temporary shut down of the West Elk mine following detection of combustion-related gases in a portion of the mine. This final insurance settlement has been recognized as a reduction in the cost of coal sales.

  •  Year ended December 31, 2001

        We were notified by the Bureau of Land Management that we would receive a royalty rate reduction for certain tons mined at our West Elk mine. The rate reduction applies to a specified number of tons beginning October 1, 2001 and ending no later than October 1, 2005. The retroactive portion of the refund totaled $3.3 million and has been recognized as a reduction in the cost of coal sales.

Year Ended December 31, 2001, Compared to Year Ended December 31, 2000

      Results for 2001 were positively impacted by strong margins on the limited tonnage open to market-based pricing during the early part of 2001. Results for both 2001 and 2000 were negatively impacted by significant production difficulties at our West Elk mine. In 2000, the mine was idled from January 28, 2000 to July 12, 2000, following the detection of combustion gases in a portion of the mine. In 2001, the mine experienced high methane levels (unrelated to the combustion gases) that negatively impacted production. The operating losses at West Elk were offset to some extent by insurance settlements of $31.0 million in 2000 and $9.4 million 2001 under our business interruption policy.

      Operating results for 2001 versus 2000 and additional discussion of the 2001 results are provided below.

      Coal sales. The increase in coal sales in 2001 was the result of 5.2 million additional tons shipped in 2001 compared to 2000, higher average pricing on coal shipped during 2001 as compared to 2000 and additional sales from our West Elk mine as compared to the previous year. Average realizations on a per ton basis were $6.35 per ton in 2001 as compared to $5.74 in 2000. The increase resulted from higher spot market pricing during the early part of 2001 on a limited number of spot market tons sold. The increase in tons sold resulted from higher production at our Black Thunder and West Elk mines, offset partially by the idling of our Coal Creek mine in 2000. Coal sales in 2000 were adversely impacted by reduced production at our West Elk mine due to its idling as discussed above. After moving to another section of the mine, production was hampered by methane gas in 2001, however, production and sales levels were significantly higher than 2000 levels.

      Income from equity investment. During 2001, Canyon Fuel recognized recoveries of previously paid property taxes. Our share of these recoveries is $2.6 million. In addition, Canyon Fuel experienced improved performance at its three underground mines in Utah.

      Other revenues. Other revenues increased in 2001 due to a $5.1 million gain on a land sale in Wyoming and the amortization of a $4.9 million deferred gain resulting from the renegotiation of a sales contract. The deferred gain was amortized over the remaining tons to be shipped under the contract.

      Cost of coal sales. The increase in cost of coal sales resulted from increased tons sold and a change in mix, primarily from increased tons produced from our West Elk mine, which has a higher cost structure than the Black Thunder mine. Additional costs were incurred at our West Elk mine during 2001 resulting

from efforts to control methane gas levels. This was partially offset by $9.4 million of insurance proceeds received as the final insurance settlement from the temporary mine closure related to the year-2000 combustion gases. These insurance proceeds are reflected as a reduction in cost of coal sales. The costs associated with the West Elk mine closure in 2000 were partially offset by insurance proceeds of $31.0 million received in that year.

      Selling, general and administrative expenses. The cost increase for the year ended 2001 compared to the prior year is a result of additional costs associated with bonus accruals.

      Amortization of coal supply agreements. The decrease in amortization of coal supply agreements results from an above market contract that terminated in 2000.

Outlook

      Production Levels. We reduced our overall rate of coal production by approximately 8% during the first quarter of 2003. This was in addition to a reduction in overall production of approximately 1% during 2002. These actions were taken in response to unfavorable spot coal markets following an extremely mild winter in 2001-2002, a period of industrial economic weakness that dampened electricity demand and an effort by electric utilities to reduce coal stockpile levels. Although the timing of any recovery in coal markets remains uncertain, there have been indications that prices may return to more favorable levels in the future. These indications include more normal weather patterns, some indication of economic recovery and an overall decrease in coal production and utility stockpiles.

      Postretirement Obligations. We expect to incur significantly higher expense charges related to postretirement obligations in 2003. Our portion of these obligations, which include increases in post-retirement healthcare and pension-related expenses, increased our costs by approximately $0.5 million during the first quarter of 2003 and are expected to increase non-cash costs by approximately $0.5 million per quarter from prior year levels for the remainder of the year.

      Cash provided by operating activities decreased in the three months ended March 31, 2003 as compared to same period in 2002 due primarily to decreased distributions from Canyon Fuel and to an increase in our receivable from Arch Coal.

      Cash used in investing activities decreased in the three months ended March 31, 2003 as compared to the similar period in 2002 due to decreased capital expenditures primarily at Black Thunder.

      Expenditures for property, plant and equipment were $6.4 million and $21.9 million for the three months ended 2003 and 2002, respectively. Capital expenditures are made to improve and replace existing mining equipment, expand existing mines, develop new mines and improve the overall efficiency of mining operations. In the first quarter of 2002, we replaced several pieces of mobile equipment at Black Thunder.

Financing activities
                (4,193 )

      Cash provided by operating activities increased in 2002 as compared to 2001 due primarily to improved operating performance and reduced requirements for working capital components other than inventories. Cash provided by operating activities increased in 2001 compared to 2000 due primarily to improved operating performance in 2001, increased distributions from our equity investment in Canyon Fuel, and reduced working capital requirements in 2001 compared to 2000. Results of operations in 2000 were negatively impacted by the detection of combustion related gases in our underground West Elk mine. The mine was idled for the period January 28, 2000 through July 12, 2000. The negative impact of this event was partially offset by $31 million in insurance proceeds received in 2000.

      Cash used in investing activities increased in 2002 as compared to 2001 due to increased capital expenditures primarily at Black Thunder and increased prepaid royalty payments. Cash used in investing activities in 2001 increased compared to 2000 due primarily to higher capital expenditures in 2001 that were partially offset by proceeds on the sale of a tract of land in Wyoming. The increased capital additions in 2001 were attributable to various de-gasification systems that were constructed at West Elk to remove the methane gas that was encountered when the longwall was moved to a new section of the mine.

      Expenditures for property, plant and equipment were $51.4 million, $32.1 million and $28.5 million for 2002, 2001 and 2000, respectively. The increase in capital expenditures in 2002 compared to 2001 resulted primarily from the scheduled purchase of assets from an operating lease and the replacement of several pieces of mobile equipment at Black Thunder.

      Cash used in financing activities during 2002 represents costs associated with the debt refinancing that occurred in the first quarter of 2002, as described below. Our cash transactions are managed by Arch Coal. Cash paid to or from us that is not considered a distribution or a contribution is maintained in an Arch Coal receivable account. At December 31, 2002, 2001 and 2000, the receivable from Arch Coal was $333.8 million, $259.8 million and $189.2, respectively. The receivable is interest bearing and is payable on demand by us. However, we do not intend to demand payment of the receivable within the next year. Therefore, the receivable is classified on the consolidated balance sheets as long-term.

      We generally satisfy our working capital requirements and fund our capital expenditures and debt-service obligations with cash generated from operations. We believe that cash generated from operations will be sufficient to meet our working capital requirements and anticipated capital expenditures for the next several years. Our ability to fund planned capital expenditures and meet our debt-service obligations will depend upon our future operating performance, which will be affected by prevailing economic conditions in the coal industry, and by financial, business and other factors, some of which are beyond our control.

      On April 18, 2002, we refinanced our then existing credit facilities. The new credit facility included a five-year non-amortizing term loan for $150.0 million and a six-year non-amortizing term loan of $525.0 million. The rate of interest under both term loans was a floating rate based on LIBOR. The credit facility was secured by our ownership interest in all of our subsidiaries. We used the net proceeds from the sale of the old notes to repay and retire the outstanding indebtedness under our credit facility.

      The terms of our LLC Agreement provide for a preferred return distribution in an amount equal to 4% of the preferred capital account balance, which was $2.4 million for each of the years ended December 31, 2000, 2001 and 2002. Preferred distributions made during the years ended December 31, 2002, 2001, and 2000 were $0.1 million in each year. Except for the preferred return distribution, distributions may generally be made at such times and in such amounts as Arch Coal, as the managing member, determines. We made no distributions other than the preferred return in the years ended December 31, 2002, 2001 and 2000.

      We are exposed to commodity price risk related to our purchase of diesel fuel. We enter into forward purchase contracts and heating oil swaps to substantially eliminate volatility in the price of diesel fuel for our operations. The swap agreements essentially fix the price paid for diesel fuel by requiring us to pay a fixed heating oil price and receive a floating heating oil price. The changes in the floating heating oil price highly correlate to changes in diesel fuel prices. Gains and losses on terminations of heating oil swap agreements are deferred on the balance sheet (in other long-term liabilities) and amortized as an adjustment to diesel fuel cost over the original term of the terminated heating oil swap agreement as if it were still in place.

      The discussion below presents the sensitivity of the market value of our financial instruments to selected changes in market rates and prices. The range of changes reflects our view of changes that are reasonably possible over a one-year period. Market values are the present value of projected future cash flows based on the market rates and prices chosen. The major accounting policies for these instruments are described in Note 1 to our consolidated financial statements.

      Changes in interest rates have different impacts on the fixed-rate and variable-rate portions of our debt portfolio. A change in interest rates on the fixed portion of our debt portfolio impacts the net financial instrument position but has no impact on interest incurred or cash flows. A change in interest rates on the variable portion of the debt portfolio impacts the interest incurred and cash flows but does not impact the net financial instrument position.

      The sensitivity analysis related to the fixed portion of our debt portfolio assumes an instantaneous 100-basis-point change in interest rates from their levels at December 31, 2002, with all other variables held constant. A 100-basis-point decrease in market interest rates would result in a $17.1 million increase in the fair value of the fixed portion of the debt at December 31, 2002. Based on the variable-rate debt included in our debt portfolio as of December 31, 2002, after considering the effect of the swap

33


Table of Contents

agreements, a 100-basis-point increase in interest rates would result in an annualized additional $3.6 million of interest expense incurred based on December 31, 2002 debt levels. At December 31, 2002, a $.05 per gallon decrease in the price of heating oil would result in a $0.2 million decrease in the fair value of the financial position of the heating oil swap agreements.

      Unconditional purchase obligations represent amounts committed for capital expenditures. In addition to these contractual obligations, we expect to make contributions of $7.6 million to our pension plan in 2003.

Contingencies

 
Reclamation

      The federal Surface Mining Control and Reclamation Act of 1977 and similar state statutes require that mine property be restored in accordance with specified standards and an approved reclamation plan. We accrue for the costs of final mine closure reclamation in accordance with the provisions of FAS 143, which was adopted as of January 1, 2003. These costs relate to reclaiming the pit and support acreage at surface mines and sealing portals at deep mines. Other costs of final mine closure common to surface and underground mining are related to reclaiming refuse and slurry ponds, eliminating sedimentation and drainage control structures, and dismantling or demolishing equipment or buildings used in mining operations. The establishment of the final mine closure reclamation liability is based upon permit requirements and requires various estimates and assumptions, principally associated with costs and productivities.

      We review our entire environmental liability periodically and make necessary adjustments, including permit changes and revisions to costs and productivities to reflect current experience. Our management believes it is making adequate provisions for all expected reclamation and other associated costs.

 
Legal Contingencies

      We are party to claims and lawsuits with respect to various matters. We provide for costs related to contingencies, including environmental matters, when a loss is probable and the amount is reasonably determinable. After conferring with counsel, it is the opinion of management that the ultimate resolution of these claims, to the extent not previously provided for, will not have a material adverse effect on our consolidated financial condition, results of operations or liquidity.

Losses

      Because the coal mining industry is subject to significant regulatory oversight and affected by the possibility of adverse pricing trends or other industry trends beyond our control, we may suffer losses in the future if legal and regulatory rulings, mine idlings and closures, adverse pricing trends or other factors affect our ability to mine and sell coal profitably.

Critical Accounting Policies

      Our financial statements are prepared in accordance with accounting principles that are generally accepted in the United States. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses as well as the disclosure of contingent assets and liabilities. Our management bases its estimates and judgments on historical experience and other factors that are believed to be reasonable under the circumstances. Actual results may differ from the estimates used under different assumptions or conditions. Note 1 to our consolidated financial statements provides a description of all significant accounting policies. We believe that of these significant accounting policies, the following may involve a higher degree of judgment or complexity.

     Accrued Reclamation and Mine Closure Costs

      The federal Surface Mining Control and Reclamation Act of 1977 and similar state statutes require that mine property be restored in accordance with specified standards and an approved reclamation plan. Significant reclamation activities include reclaiming refuse and slurry ponds, reclaiming the pit and support acreage at surface mines, and sealing portals at deep mines. We accrue for the cost of final mine closure reclamation over the estimated useful mining life of the property. We determine the total amount to be accrued on a mine-by-mine basis based upon current permit requirements and various estimates and assumptions, including estimates of disturbed acreage, cost estimates, and assumptions regarding productivity. Estimates of disturbed acreage are determined based on engineering data. Cost estimates are based upon historical internal or third-party costs, depending on how the work is expected to be performed. Productivity assumptions are based on historical experience with the equipment that is expected to be utilized in the reclamation activities. On at least an annual basis, we review our entire reclamation liability and makes necessary adjustments for permit changes as granted by state authorities, additional costs resulting from accelerated mine closures, and revisions to cost estimates and productivity assumptions, to reflect current experience. At December 31, 2002 and 2001, we had recorded reclamation and mine closure liabilities of $69.1 million and $62.9 million, respectively. While the precise amount of these future costs cannot be determined with certainty, as of December 31, 2002, we estimate that the aggregate undiscounted cost of final mine closure is approximately $220.6 million.

      Effective January 1, 2003, we adopted FAS 143, Accounting for Asset Retirement Obligations, which significantly changes the way in which we account for our reclamation and mine closure liabilities. The statement requires legal obligations associated with the retirement of long-lived assets to be recognized at their fair value at the time that the obligations are incurred. Upon initial recognition of a liability, that cost is capitalized as part of the related long-lived asset and allocated to expense over the useful life of the asset. The initial adoption of FAS 143 resulted in a cumulative effect loss of $18.3 million as of January 1, 2003.

      The amount of the asset retirement obligation depends on the estimates and assumptions discussed above, as well as the following:

  •  Discount rate — FAS 143 requires the asset retirement obligation to be recorded at its fair value. In accordance with the provisions of FAS 143, we utilized discounted cash flow techniques to estimate the fair value of our obligations. The rates that we used are based on rates for treasury bonds with maturities similar to expected mine lives, adjusted for our credit standing.

35


Table of Contents

  •  Third-party margin — FAS 143 requires the measurement of an obligation to be based upon the amount a third party would demand to assume the obligation. Because we plan to perform a significant amount of our final mine closure reclamation activities with internal resources, a third-party margin was added to the estimated costs of these activities. This margin was estimated based on our historical experience with contractors performing certain types of reclamation activities. The inclusion of this margin will result in a recorded obligation that is greater than our estimates of our cost to perform the reclamation activities. If our cost estimates are accurate, the excess of the recorded obligation over the cost incurred to perform the work will be recorded as a gain at the time that reclamation work is completed.

      At March 31, 2003, we had recorded asset retirement obligations of $112.6 million.

     Employee Benefit Plans

      We have non-contributory defined benefit pension plans covering certain of our salaried and non-union hourly employees. Benefits are generally based on the employee’s years of service and compensation. We fund the plans in an amount not less than the minimum statutory funding requirements nor more than the maximum amount that can be deducted for federal income tax purposes. We account for our defined benefit plans in accordance with FAS 87, Employer’s Accounting for Pensions, which requires amounts recognized in the financial statements to be determined on an actuarial basis.

      We also currently provide certain postretirement medical/life insurance coverage for eligible employees. Generally, covered employees who terminate employment after meeting eligibility requirements are eligible for postretirement coverage for themselves and their dependents. The salaried employee postretirement medical/life plans are contributory, with retiree contributions adjusted periodically, and contain other cost-sharing features such as deductibles and coinsurance. The postretirement medical plan for retirees who were members of the United Mine Workers of America is not contributory. Our current funding policy is to fund the cost of all postretirement medical/life insurance benefits as they are paid. We account for our other postretirement benefits in accordance with FAS 106, Employer’s Accounting for Postretirement Benefits Other Than Pensions, which requires amounts recognized in the financial statements to be determined on an actuarial basis.

      Various actuarial assumptions are required to determine the amounts reported as obligations and costs related to the pension and postretirement benefit plans. These assumptions include the discount rate, future cost trend rates and future rates of return for pension plan assets. Each of these assumptions is discussed further below:

  •  The discount rate assumption reflects the rates available on high-quality fixed-income debt instruments at year end.
 
  •  Future cost trend rates include the rate of compensation increase for the pension obligation and the health care cost trend rate for other postretirement benefit obligations. The rate of compensation increase is determined based upon our long-term plans for such increases. The health care cost trend rate is determined based upon our own historical trends for health care costs as well as external data regarding such costs.
 
  •  Assumptions regarding future rates of return for pension plan assets are based on long-term historical actual return information for the mix of investments that comprise plan assets, and future estimates of long-term investment returns.

BUSINESS

      We are one of the largest and most productive operators of compliance and low sulfur coal mines in the United States. We sold 72.5 million tons of coal in 2002 and 15.8 million tons of coal during the three months ended March 31, 2003, all of which was compliance and low sulfur coal. We have a total of seven operating mines. Our largest mine, Black Thunder, is located in Wyoming in the Powder River Basin, the largest and fastest-growing U.S. coal-producing region. Black Thunder is the second largest coal mine in the United States. We are the largest producer of coal in the Western Bituminous Region, where we directly own three mines in Colorado and Wyoming and a 65% interest in Canyon Fuel Company, LLC, which owns and operates three mines in Utah, one of which is scheduled to be idled by June 30, 2004.

      As of March 31, 2003, we controlled approximately 1.9 billion tons of proven and probable compliance and low sulfur coal reserves. Approximately 93.5% of our reserves is compliance coal, which does not require generators of electricity to use sulfur dioxide reduction technologies to comply with the requirements of the Clean Air Act.

      We sell substantially all of our coal to producers of electric power, most of whom are large, investment grade utilities. Currently, we have sales contracts in place for approximately 96% of our planned 2003 production and approximately 64% of our planned 2004 production. This provides us with a relatively reliable and stable revenue base through the end of 2004. Our goal with respect to the remainder of our planned production is to seek long-term supply agreements with our largest and best customers as coal markets strengthen.

Operations

      As of March 31, 2003, we operated a total of seven mines, all located in the western United States. Coal is transported from our mining complexes to customers by railroad cars. As is customary in the industry, virtually all of our coal sales are made F.O.B. mine or loadout, meaning that customers are responsible for the cost of transporting purchased coal to their facilities. The following table provides the location and summary information regarding our principal mining complexes and the coal reserves associated with these operations as of December 31, 2002.

(3)  Operated by Canyon Fuel. Canyon Fuel is an equity investment, and its financial statements and tons produced are not consolidated into our financial statements and tons produced. Amounts represent 100% of Canyon Fuel’s production and assigned reserves, of which we have a 65% interest. The Skyline mine is scheduled to be idled by June 30, 2004.
 
(4)  Utilizes 76-cubic-yard dragline at Medicine Bow and a 32-cubic-yard dragline at Seminoe II.

      Black Thunder. The Black Thunder mine is located in Campbell County, Wyoming on approximately 14,711 acres. Mining the approximately 68-foot coal seam are four draglines and seven shovels. There is no washing plant at Black Thunder. The coal is crushed through either the near pit crushing and conveying system or the primary system. Coal from these two crushing facilities is conveyed into one of two silos or a slot storage facility. Coal is shipped through two loadouts on trains operated by Burlington Northern and Union Pacific.

      Coal Creek. The Coal Creek mine is located in Campbell County, Wyoming on approximately 6,720 acres. Coal Creek has been idle since July 2000. The equipment at the mine consists of one shovel, ten trucks and a loadout facility. The Coal Creek mine is located on a joint rail line operated by Burlington Northern and Union Pacific.

      West Elk. The West Elk mine is an underground operation located in Gunnison County, Colorado on approximately 14,700 acres. The coal is mined by two continuous mines in support of a longwall. The loadout facility at the mine is serviced by the Union Pacific Railroad services the mine.

      Medicine Bow. The Medicine Bow mine is located in Carbon County, Wyoming. The Medicine Bow mine has 20,352 permitted acres. Two draglines operate in the mine and the mined coal is processed through a preparation plant. The loadout facility at Medicine Bow is serviced by the Union Pacific Railroad.

      Seminoe II. The Seminoe II mine controls 9,631 permitted acres. One dragline operates in the mine with the mined coal processed through a preparation plant with a capacity of 1,000 tons per hour. The loadout facility capacity is 5,000 tons per hour, and the loadout is serviced by the Union Pacific Railroad.

      Skyline. Canyon Fuel’s Skyline mine is an underground longwall mine located in Carbon County and Emery County, Utah on 11,300 acres. Three continuous miners support a longwall. The coal produced from the mine is crushed and loaded into trains at the mine. The loadout facility at Skyline is serviced by the Union Pacific Railroad. The Skyline mine is scheduled to be idled by June 30, 2004 because current market prices do not support expansion into an additional reserve base at the mine.

      SUFCO. Canyon Fuel’s SUFCO mine, an underground longwall mine, is located in Sevier County, Juab County and Emery County, Utah on 23,900 acres. Two continuous miners support the longwall. All of the coal produced from the mine is crushed at a facility located at the mine and trucked either directly to customers or to a train loadout located approximately 80 miles from the mine. The Union Pacific Railroad serves this loadout.

      Dugout Canyon. Canyon Fuel’s Dugout Canyon mine is an underground longwall mine located in Carbon, County, Utah on 13,700 acres. Two continuous miners support the longwall operation. The coal produced is crushed at the mine and trucked to a third party loadout served by the Union Pacific Railroad.

      We currently own or lease the equipment utilized in our mining operations.

Coal Reserves

      As of December 31, 2002, we estimate that we controlled approximately 1.9 billion tons of assigned and unassigned proven and probable recoverable reserves. Recoverable reserves include only saleable coal and do not include coal which would remain unextracted. Reserve estimates are prepared by our engineers and geologists and reviewed and updated periodically. Total recoverable reserve estimates and reserves dedicated to mines and complexes change from time to time to reflect mining activities, analysis of new engineering and geological data, changes in reserve holdings and other factors. Our recoverable reserves

Including 100% of the reserves held by Canyon Fuel, in which we have a 65% interest.

      As of December 31, 2002, approximately 86,688 acres (which includes 100% of the acreage held by Canyon Fuel) of our total of approximately 180,833 acres of coal land were leased by a subsidiary of Arch Coal from the federal government. We have subleased those federal lands from that subsidiary of Arch Coal. In addition, approximately 41,200 acres were leased by us from state governments, and approximately 32,650 acres were leased by us from private lessors. These leases have terms expiring between 2004 and 2027, subject to readjustment or extension and to earlier termination for failure to meet development requirements.

      All of the identified coal reserves held by us have been subject to preliminary coal seam analysis to test sulfur content. Of these reserves, approximately 93.5% consist of compliance coal. Accordingly, our reserves are primarily suitable for the domestic steam coal markets.

      Our federal coal leases are administered by the U.S. Department of the Interior under the Federal Coal Leasing Amendments Act of 1976. These leases cover our principal reserves in Wyoming and other reserves in Utah and Colorado. The Bureau of Land Management has asserted the right to adjust the terms and conditions of these leases, including rent and royalties, after the first 20 years of their term and at ten-year intervals thereafter. Annual rents under our federal coal leases are now set at $3.00 per acre. Production royalties on federal leases are set by statute at 12.5% of the gross proceeds of coal mined and sold for surface-mined coal and 8% for underground-mined coal. The federal government limits by statute the amount of federal land that may be leased by any company and its affiliates at any time to 75,000 acres in any one state and 150,000 acres nationwide. As of March 31, 2003, we leased or had applied to lease 11,230 acres of federal land in Colorado, 40,909 acres in Utah and 37,348 acres in Wyoming.

      Title to coal properties that we lease or purchase and the boundaries of such properties generally are verified at the time of leasing or acquisition. However, in cases involving less significant properties and consistent with industry practices, title and boundaries are not completely verified until such time as we prepare to mine such reserves. If defects in title or boundaries of undeveloped reserves are discovered in the future, control of and the right to mine such reserves could be adversely affected.

39


Table of Contents

      From time to time, private lessors or subleasors of land leased by us have sought to terminate such leases on the basis that we have failed to comply with the financial terms of the leases or that the mining and related operations conducted by us are not authorized by the leases. Some of these allegations relate to leases upon which we conduct operations material to our consolidated financial position, results of operations and liquidity, but we do not believe any pending claims by such leasors or subleasors have merit or will result in the termination of any material lease or sublease.

      We must obtain permits from applicable state regulatory authorities before we begin to mine reserves. Applications for permits require extensive engineering and data analysis and presentation and must address a variety of environmental, health and safety matters associated with a proposed mining operation. These matters include the manner and sequencing of coal extraction, the storage, use and disposal of waste and other substances and other impacts on the environment, the construction of overburden fills and water containment areas and reclamation of the area after coal extraction. We are required to post bonds to secure our performance under our permits. As is typical in the coal industry, we strive to obtain mining permits within a time frame that allows us to mine reserves as planned on an uninterrupted basis. We generally begin preparing applications for permits for areas that we intend to mine up to three years in advance of their expected issuance date. Regulatory authorities have considerable discretion in the timing of permit issuance and the public has rights to comment on and otherwise engage in the permitting process, including through intervention in the courts.

      Our reported coal reserves are those that could be economically and legally extracted or produced at the time of their determination. In determining whether our reserves meet this standard, we take into account, among other things, our potential inability to obtain a mining permit, the possible necessity of revising a mining plan, changes in estimated future costs, changes in future cash flows caused by changes in costs required to be incurred to meet regulatory requirements and obtaining mining permits, variations in quantity and quality of coal, and varying levels of demand and their effects on selling prices. We are not currently aware of matters which would significantly hinder our ability to obtain future mining permits with respect to our reserves.

      The carrying cost of our coal reserves at December 31, 2002 was $577.8 million.

ARCH WESTERN FINANCE, LLC

      The Issuer is a Delaware limited liability company and an indirectly wholly-owned subsidiary of Arch Western. It was formed on June 3, 2003 solely for the purpose of being the issuer of the old notes and the registered notes. The Issuer has no operations, and we do not expect that it will have operations in the future. The Issuer’s only asset is the intercompany note issued by Thunder Basin Coal Company, L.L.C. evidencing the proceeds from the sale of the old notes that will be loaned to Thunder Basin and, in turn, loaned to us to repay our existing bank debt and for general purposes.

ARCH COAL, INC.

      Arch Coal originally was organized as Arch Mineral Corporation in 1969. On July 1, 1997, Ashland Coal, Inc. then a majority-owned subsidiary of Ashland Inc., merged with a subsidiary of Arch Mineral Corporation. In connection with the merger, the name of Arch Mineral Corporation was changed to Arch Coal, Inc. On June 1, 1998, Arch Coal acquired the United States coal operations of Atlantic Richfield Company for an aggregate of approximately $1.14 billion in cash and combined these operations with its western operations to form Arch Western Resources, LLC. Arch Coal owns 99% of Arch Western, and an affiliate of BP p.l.c., the successor to Atlantic Richfield Company, owns the remaining 1% interest.

      Arch Coal is the second largest and one of the most productive operators of compliance and low sulfur coal mines in the United States. Including our operations, as of March 31, 2003, Arch Coal controlled approximately 2.9 billion tons of proven and probable coal reserves. As of March 31, 2003, Arch Coal had 25 operating mines. Arch Coal sold 106.7 million tons of coal in 2002 and 22.7 million tons of coal during the three months ended March 31, 2003.

40


Table of Contents

      In addition to our operations, Arch Coal produces coal in Central Appalachia in the eastern United States. Arch Coal produces compliance and low sulfur coal exclusively, and 90% of its reserves are compliance quality or low sulfur. Arch Coal supplied the fuel for approximately 6% of the electricity used in the United States in 2002. In the past five years, Arch Coal has increased its coal production from 36.7 million tons in 1997 to 99.6 million tons in 2002, primarily as a result of selective acquisitions as well as the strategic development of existing reserves.

      Arch Coal’s common stock is listed on the New York Stock Exchange and traded under the symbol “ACI.” Based on the closing price of Arch Coal common stock on July 31, 2003 of $20.55, its market capitalization was approximately $1.2 billion.

      On May 29, 2003, Arch Coal entered into a definitive agreement to acquire (1) Vulcan, which owns all of the common equity of Triton, and (2) all of the preferred units of Triton, for a purchase price of $364.0 million. Consummation of the transaction is subject to various conditions, including the receipt by Arch Coal and Vulcan of all necessary governmental and regulatory consents and other customary conditions. Arch Coal will finance the acquisition with cash and borrowed funds.

      Triton is the nation’s seventh largest coal producer and the operator of two mines in the Powder River Basin. These mines, North Rochelle and Buckskin, produced a combined total of 42.2 million tons of coal in 2002 and are supported by approximately 744 million tons of proven and probable reserves. The North Rochelle mine produces 8,800 Btu super-compliance quality coal on a reserve base of approximately 250 million tons. In 2002, North Rochelle produced 23.9 million tons of coal. The Buckskin mine produces 8,400 Btu compliance quality coal on a reserve base of approximately 494 million tons. In 2002, Buckskin produced 18.3 million tons of coal.

      The acquisition of Triton would increase Arch Coal’s total reserves in the Powder River Basin by approximately 50%, from 1.6 billion tons to 2.3 billion tons. North Rochelle and Black Thunder are contiguously located, sharing a 5.5-mile property line. Arch Coal has identified expected synergies of approximately $18 million to $22 million annually that may be realized through the operational integration of Triton’s North Rochelle mine and our Black Thunder mine. Although Arch Coal plans to integrate the operations of the Black Thunder and North Rochelle mines, Triton’s financial results are not expected to be part of our consolidated financial results.

      For further information about Arch Coal, see the documents incorporated by reference into this prospectus that Arch Coal has filed with the Securities and Exchange Commission which are listed under the heading “Where You Can Find More Information” and which are filed in the future under Section 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934 until the exchange offer is completed.

THE EXCHANGE OFFER

Purpose and Effect

      The Issuer issued the old notes on June 25, 2003 in a private placement to a limited number of qualified institutional buyers, as defined under the Securities Act. In connection with that issuance, the Issuer, Arch Western and the subsidiary guarantors entered into the indenture and, with Arch Coal, the registration rights agreement. These agreements require that we file a registration statement under the Securities Act with respect to the registered notes to be issued in the exchange offer and, upon the effectiveness of the registration statement, offer to you the opportunity to exchange your old notes for a like principal amount of registered notes. The registered notes will be issued without a restrictive legend, and, except as set forth below, we believe that the registered notes may be reoffered and resold by you without registration under the Securities Act. After we complete the exchange offer, our obligations with respect to the registration of the old notes will terminate, except as provided in the last paragraph of this section. A copy of the indenture and the registration rights agreement have been filed as exhibits to the registration statement of which this prospectus is part.

      Based on an interpretation by the staff of the SEC set forth in no-action letters issued to third parties unrelated to us, if you are not our “affiliate” within the meaning of Rule 405 under the Securities Act or a broker-dealer referred to in the next paragraph, we believe that registered notes to be issued to you in the exchange offer may be offered for resale, resold and otherwise transferred by you, without compliance with the registration and prospectus delivery provisions of the Securities Act. This interpretation, however, is based on your representations to us that:

        (1) the registered notes to be issued to you in the exchange offer are acquired in the ordinary course of your business;
 
        (2) you are not engaging in and do not intend to engage in a distribution of the registered notes to be issued to you in the exchange offer;
 
        (3) you have no arrangement or understanding with any person to participate in the distribution of the registered notes to be issued to you in the exchange offer; and
 
        (4) you are not an “affiliate” of ours, as defined under Rule 405 of the Securities Act.

      If you tender your old notes in the exchange offer for the purpose of participating in a distribution of the registered notes to be issued to you in the exchange offer, you cannot rely on this interpretation by the staff of the SEC. Under those circumstances, you must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction. Each broker-dealer that receives registered notes in the exchange offer for its own account in exchange for old notes that were acquired by the broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of those registered notes. See “Plan of Distribution.”

      If (i) due to any change in law or applicable interpretations thereof by the SEC’s staff, the Issuer, Arch Coal, Arch Western and the subsidiary guarantors determine that they are not permitted to effect the exchange offer; (ii) for any other reason the exchange offer is not consummated within 225 days of the date of issuance of the old notes; (iii) any initial purchaser of the old notes so requests with respect to old notes that are not eligible to be exchanged for registered notes in the exchange offer and that are held by it following consummation of the exchange offer; (iv) any holder (other than an initial purchaser of old notes) is not eligible to participate in the exchange offer; or (v) you are an initial purchaser of old notes that does not receive freely tradeable registered notes in exchange for old notes constituting any portion of an unsold allotment, we will register your old notes in a “shelf” registration statement on an appropriate form pursuant to Rule 415 under the Securities Act. If we are obligated to file a shelf registration statement, we will be required to keep the shelf registration statement effective until the earliest of (a) two years from the date the shelf registration statement is declared effective by the SEC or (b) such shorter period that will terminate when all securities covered by the shelf registration statement have been

44


Table of Contents

sold pursuant to the shelf registration statement. Other than as set forth in this paragraph, you will not have the right to require us to register your old notes under the Securities Act. See “— Procedures for Tendering” below.

      We will, in the event a shelf registration statement is filed, among other things, provide to each holder for whom the shelf registration statement was filed a copy of the shelf registration statement, and each amendment of the shelf registration statement and each amendment or supplement to the prospectus included in the shelf registration statement, notify each of those holders when the shelf registration statement has been filed with the SEC and when the shelf registration statement or any post-effective amendment to it has become effective and take certain other actions as are required to permit unrestricted resales of the old notes. A holder selling old notes pursuant to the shelf registration statement generally would be required to be named as a selling security holder in the related prospectus and to deliver a prospectus to purchasers, will be subject to certain of the civil liability provisions under the Securities Act in connection with such sales and will be bound by the provisions of the registration rights agreement which are applicable to that holder (including certain indemnification obligations).

      We will pay additional cash interest on the old notes, subject to certain exceptions, if:

        (1) the registration statement of which this prospectus is part is not declared effective on or prior to the 180th day following the date of the issuance of the old notes;
 
        (2) the exchange offer is not consummated on or prior to the 225th day following the date of the issuance of the old notes; or
 
        (3) if required, a shelf registration statement with respect to the old notes has not been filed with the SEC on or prior to the 60th day following the date the obligation to file the shelf registration statement arises

(each such event referred to in clauses (1) through (3) above, a “Registration Default”) from and including the date on such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured.

      The rate of additional interest will be at the rate equal to 0.25% of the principal amount of the old notes (determined daily) with respect to the first 90-day period following such Registration Default. The amount of additional interest will increase by an additional 0.25% per annum to a maximum of 1.00% per annum for each subsequent 90-day period until the Registration Default has been cured. We will pay the additional interest on regular interest payment dates. The additional interest will be in addition to any other interest payable from time to time with respect to the notes.

      All references in the indenture, in any context, to any payment of principal, purchase prices in connection with a purchase of notes, and interest or any other amount payable on or with respect to any of the notes, shall be deemed to include payment of any additional cash interest pursuant to the registration rights agreement.

Consequences of Failure to Exchange

      After we complete the exchange offer, if you have not tendered your old notes, you will not have any further registration rights, except as set forth above. Your old notes will continue to be subject to certain restrictions on transfer. Therefore, the liquidity of the market for your old notes could be adversely affected upon completion of the exchange offer if you do not participate in the exchange offer.

Terms of the Exchange Offer

      Upon the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal, we will accept any and all old notes validly tendered and not withdrawn prior to 5:00 p.m., New York City time, on the expiration date. We will issue $1,000 principal amount of registered notes in exchange for each $1,000 principal amount of old notes accepted in the exchange offer. You may tender

45


Table of Contents

some or all of your old notes pursuant to the exchange offer. However, old notes may be tendered only in integral multiples of $1,000 principal amount.

      The form and terms of the registered notes are substantially the same as the form and terms of the old notes, except that the registered notes to be issued in the exchange offer have been registered under the Securities Act and will not bear legends restricting their transfer. The registered notes will be issued pursuant to, and entitled to the benefits of, the indenture. The indenture also governs the old notes. The registered notes and the old notes will be deemed one issue of notes under the indenture.

      As of the date of this prospectus, $700.0 million in aggregate principal amount of 6 3/4% Senior Notes due 2013 were outstanding. This prospectus, together with the letter of transmittal, is being sent to all registered holders and to others believed to have beneficial interests in the old notes. You do not have any appraisal or dissenters’ rights in connection with the exchange offer under the General Corporation Law of the State of Delaware or the indenture. We intend to conduct the exchange offer in accordance with the applicable requirements of the Exchange Act and the rules and regulations of the SEC promulgated under the Exchange Act.

      We will be deemed to have accepted validly tendered outstanding notes when, as, and if we have given oral or written notice of our acceptance to the exchange agent. The exchange agent will act as our agent for the tendering holders for the purpose of receiving the registered notes from us. If we do not accept any tendered notes because of an invalid tender, the occurrence of certain other events set forth in this prospectus or otherwise, we will return certificates for any unaccepted old notes, without expense, to the tendering holder as promptly as practicable after the expiration date.

      You will not be required to pay brokerage commissions or fees or, except as set forth below under “ — Transfer Taxes,” transfer taxes with respect to the exchange of your old notes in the exchange offer. We will pay all charges and expenses, other than certain applicable taxes, in connection with the exchange offer. See “ — Fees and Expenses” below.

Expiration Date; Amendments

      The exchange offer will expire at 5:00 p.m., New York City time, on                               , 2002, unless we determine, in our sole discretion, to extend the exchange offer, in which case, it will expire at the later date and time to which it is extended. We currently do not intend to extend the exchange offer, although we reserve the right to do so. If we extend the exchange offer, we will give oral or written notice of the extension to the exchange agent and give each registered holder notice by means of a press release or other public announcement of any extension prior to 9:00 a.m., New York City time, on the next business day after the scheduled expiration date.

      We also reserve the right, in our sole discretion:

        (1) to delay accepting any old notes or, if any of the conditions set forth below under “ — Conditions” have not been satisfied or waived, to terminate the exchange offer by giving oral or written notice of such delay or termination to the exchange agent; or
 
        (2) to amend the terms of the exchange offer in any manner by complying with Rule 14e-l(d) under the Exchange Act to the extent that rule applies.

      We acknowledge and undertake to comply with the provisions of Rule 14e-l(c) under the Exchange Act, which requires us to pay the consideration offered, or return the old notes surrendered for exchange, promptly after the termination or withdrawal of the exchange offer. We will notify you promptly of any extension, termination or amendment.

Procedures for Tendering

     Book-Entry Interests

      The old notes were issued as global securities in fully registered form without interest coupons. Beneficial interests in the global securities, held by direct or indirect participants in DTC, are shown on, and transfers of these interests are effected only through, records maintained in book-entry form by DTC with respect to its participants.

      If you hold your old notes in the form of book-entry interests and you wish to tender your old notes for exchange pursuant to the exchange offer, you must transmit to the exchange agent on or prior to the expiration date either:

        (1) a written or facsimile copy of a properly completed and duly executed letter of transmittal, including all other documents required by such letter of transmittal, to the exchange agent at the address set forth on the cover page of the letter of transmittal; or
 
        (2) a computer-generated message transmitted by means of DTC’s Automated Tender Offer Program system and received by the exchange agent and forming a part of a confirmation of book-entry transfer, in which you acknowledge and agree to be bound by the terms of the letter of transmittal.

      In addition, in order to deliver old notes held in the form of book-entry interests:

        (1) a timely confirmation of book-entry transfer of such notes into the exchange agent’s account at DTC pursuant to the procedure for book-entry transfers described below under “ — Book-Entry Transfer” must be received by the exchange agent prior to the expiration date; or
 
        (2) you must comply with the guaranteed delivery procedures described below.

      The method of delivery of old notes and the letter of transmittal and all other required documents to the exchange agent is at your election and risk. Instead of delivery by mail, we recommend that you use an overnight or hand delivery service. In all cases, sufficient time should be allowed to assure delivery to the exchange agent before the expiration date. You should not send the letter of transmittal or old notes to us. You may request your broker, dealer, commercial bank, trust company, or nominee to effect the above transactions for you.

     Certificated Old Notes

      Only registered holders of certificated old notes may tender those notes in the exchange offer. If your old notes are certificated notes and you wish to tender those notes for exchange pursuant to the exchange offer, you must transmit to the exchange agent on or prior to the expiration date, a written or facsimile copy of a properly completed and duly executed letter of transmittal, including all other required documents, to the address set forth below under “ — Exchange Agent.” In addition, in order to validly tender your certificated old notes:

        (1) the certificates representing your old notes must be received by the exchange agent prior to the expiration date; or
 
        (2) you must comply with the guaranteed delivery procedures described below.

Procedures Applicable to All Holders

      If you tender an old note and you do not withdraw the tender prior to the expiration date, you will have made an agreement with us in accordance with the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal.

      If your old notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and you wish to tender your notes, you should contact the registered holder promptly and instruct the registered holder to tender on your behalf. If you wish to tender on your own behalf, you

47


Table of Contents

must, prior to completing and executing the letter of transmittal and delivering your old notes, either make appropriate arrangements to register ownership of the old notes in your name or obtain a properly completed bond power from the registered holder. The transfer of registered ownership may take considerable time.

      Signatures on a letter of transmittal or a notice of withdrawal must be guaranteed by an eligible institution unless:

        (1) old notes tendered in the exchange offer are tendered either

        (A) by a registered holder who has not completed the box entitled “Special Registration Instructions” or “Special Delivery Instructions” on the letter of transmittal or
 
        (B) for the account of an eligible institution; and

        (2) the box entitled “Special Registration Instructions” on the letter of transmittal has not been completed.

      If signatures on a letter of transmittal or a notice of withdrawal are required to be guaranteed, the guarantee must be by a financial institution, which includes most banks, savings and loan associations and brokerage houses, that is a participant in the Securities Transfer Agents Medallion Program, the New York Stock Exchange Medallion Program or the Stock Exchanges Medallion Program.

      If the letter of transmittal is signed by a person other than you, your old notes must be endorsed or accompanied by a properly completed bond power and signed by you as your name appears on those old notes.

      If the letter of transmittal or any old notes or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations, or others acting in a fiduciary or representative capacity, those persons should so indicate when signing. Unless we waive this requirement, in this instance you must submit with the letter of transmittal proper evidence satisfactory to us of their authority to act on your behalf.

      We will determine, in our sole discretion, all questions regarding the validity, form, eligibility, including time of receipt, acceptance and withdrawal of tendered old notes. This determination will be final and binding. We reserve the absolute right to reject any and all old notes not properly tendered or any old notes our acceptance of which would, in the opinion of our counsel, be unlawful. We also reserve the right to waive any defects, irregularities or conditions of tender as to particular old notes. Our interpretation of the terms and conditions of the exchange offer, including the instructions in the letter of transmittal, will be final and binding on all parties.

      You must cure any defects or irregularities in connection with tenders of your old notes within the time period we will determine unless we waive that defect or irregularity. Although we intend to notify you of defects or irregularities with respect to your tender of old notes, neither we, the exchange agent nor any other person will incur any liability for failure to give this notification. Your tender will not be deemed to have been made and your notes will be returned to you if:

        (1) you improperly tender your old notes;
 
        (2) you have not cured any defects or irregularities in your tender; and
 
        (3) we have not waived those defects, irregularities or improper tender.

In this event, the exchange agent will return your notes, unless otherwise provided in the letter of transmittal, as soon as practicable following the expiration of the exchange offer.

      In addition, we reserve the right in our sole discretion to:

        (1) purchase or make offers for, or offer registered notes for, any old notes that remain outstanding subsequent to the expiration of the exchange offer;

48


Table of Contents

        (2) terminate the exchange offer; or
 
        (3) to the extent permitted by applicable law, purchase notes in the open market, in privately negotiated transactions or otherwise.

      The terms of any of these purchases or offers could differ from the terms of the exchange offer.

      By tendering old notes in the exchange offer, you will represent to us that, among other things:

        (1) the registered notes to be acquired by you in the exchange offer are being acquired in the ordinary course of your business;
 
        (2) you are not engaging in and do not intend to engage in a distribution of the registered notes to be acquired by you in the exchange offer;
 
        (3) you do not have an arrangement or understanding with any person to participate in the distribution of the registered notes to be acquired by you in the exchange offer; and
 
        (4) you are not our “affiliate,” as defined under Rule 405 of the Securities Act.

      In all cases, issuance of registered notes in exchange for old notes that are accepted for exchange in the exchange offer will be made only after timely receipt by the exchange agent of certificates for your old notes or a timely book-entry confirmation of your old notes into the exchange agent’s account at DTC, a properly completed and duly executed letter of transmittal, or a computer-generated message instead of the letter of transmittal, and all other required documents. If any tendered old notes are not accepted for any reason set forth in the terms and conditions of the exchange offer or if old notes are submitted for a greater principal amount than you desire to exchange, the unaccepted or non-exchanged old notes, or old notes in substitution therefor, will be returned without expense to you. In addition, in the case of old notes tendered by book-entry transfer into the exchange agent’s account at DTC pursuant to the book-entry transfer procedures described below, the non-exchanged old notes will be credited to your account maintained with DTC, as promptly as practicable after the expiration or termination of the exchange offer.

Guaranteed Delivery Procedures

      If you desire to tender your old notes in the exchange offer and your old notes are not immediately available, you may tender your old notes if:

        (1) you tender your old notes through an eligible financial institution;
 
        (2) on or prior to 5:00 p.m., New York City time, on the expiration date, the exchange agent receives from an eligible institution, a written or facsimile copy of a properly completed and duly executed letter of transmittal and notice of guaranteed delivery, substantially in the form provided by us; and
 
        (3) the certificates for all certificated old notes, in proper form for transfer, or a book-entry confirmation, and all other documents required by the letter of transmittal, are received by the exchange agent within three New York Stock Exchange trading days after the date of execution of the notice of guaranteed delivery.

      The notice of guaranteed delivery may be sent by facsimile transmission, mail or hand delivery. The notice of guaranteed delivery must set forth:

        (1) your name and address;
 
        (2) the amount of old notes you are tendering; and
 
        (3) a statement that your tender is being made by the notice of guaranteed delivery and that you guarantee that within three New York Stock Exchange trading days after the execution of the notice

49


Table of Contents

  of guaranteed delivery, the eligible institution will deliver the following documents to the exchange agent:

        (A) the certificates for all certificated old notes being tendered, in proper form for transfer or a book-entry confirmation of tender;
 
        (B) a written or facsimile copy of the letter of transmittal, or a book-entry confirmation instead of the letter of transmittal; and
 
        (C) any other documents required by the letter of transmittal.

Book-Entry Transfer

      The exchange agent will establish an account with respect to the book-entry interests at DTC for purposes of the exchange offer promptly after the date of this prospectus. You must deliver your book-entry interest by book-entry transfer to the account maintained by the exchange agent at DTC. Any financial institution that is a participant in DTC’s systems may make book-entry delivery of book-entry interests by causing DTC to transfer the book-entry interests into the exchange agent’s account at DTC in accordance with DTC’s procedures for transfer.

      If one of the following situations occur:

        (1) you cannot deliver a book-entry confirmation of book-entry delivery of your book-entry interests into the exchange agent’s account at DTC; or
 
        (2) you cannot deliver all other documents required by the letter of transmittal to the exchange agent prior to the expiration date,

then you must tender your book-entry interests according to the guaranteed delivery procedures discussed above.

Withdrawal Rights

      You may withdraw tenders of your old notes at any time prior to 5:00 p.m., New York City time, on the expiration date.

      For your withdrawal to be effective, the exchange agent must receive a written or facsimile transmission notice of withdrawal at its address set forth below under “ — Exchange Agent” prior to 5:00 p.m., New York City time, on the expiration date.

      The notice of withdrawal must:

        (1) state your name;
 
        (2) identify the specific old notes to be withdrawn, including the certificate number or numbers and the principal amount of withdrawn notes;
 
        (3) be signed by you in the same manner as you signed the letter of transmittal when you tendered your old notes, including any required signature guarantees or be accompanied by documents of transfer sufficient for the exchange agent to register the transfer of the old notes into your name; and
 
        (4) specify the name in which the old notes are to be registered, if different from yours.

      We will determine all questions regarding the validity, form and eligibility, including time of receipt, of withdrawal notices. Our determination will be final and binding on all parties. Any old notes tendered and withdrawn will be deemed not to have been validly tendered for exchange for purposes of the exchange offer. Any old notes which have been tendered for exchange but which are not exchanged for any reason will be returned to you without cost as soon as practicable after withdrawal, rejection of tender or termination of the exchange offer. Properly withdrawn old notes may be retendered by following one of

50


Table of Contents

the procedures described under “ — Procedures for Tendering” above at any time on or prior to 5:00 p.m., New York City time, on the expiration date.

Conditions

      Notwithstanding any other provision of the exchange offer and subject to our obligations under the registration rights agreement, we will not be required to accept for exchange, or to issue registered notes in exchange for, any old notes and may terminate or amend the exchange offer, if at any time before the acceptance of any old notes for exchange any of the following events occur:

        (1) any injunction, order or decree has been issued by any court or any governmental agency that would prohibit, prevent or otherwise materially impair our ability to proceed with the exchange offer; or
 
        (2) the exchange offer violates any applicable law or any applicable interpretation of the staff of the SEC.

      These conditions are for our sole benefit, and we may assert them regardless of the circumstances giving rise to them, subject to applicable law. We also may waive in whole or in part at any time and from time to time any particular condition in our sole discretion. If we waive a condition, we may be required in order to comply with applicable securities laws to extend the expiration date of the exchange offer. Our failure at any time to exercise any of the foregoing rights will not be deemed a waiver of these rights and these rights will be deemed ongoing rights which may be asserted at any time and from time to time.

      In addition, we will not accept for exchange any old notes tendered, and no registered notes will be issued in exchange for any of those old notes, if at the time the old notes are tendered any stop order is threatened by the SEC or in effect with respect to the registration statement of which this prospectus is a part or the qualification of the indenture under the Trust Indenture Act of 1939.

      The exchange offer is not conditioned on any minimum principal amount of old notes being tendered for exchange.

DESCRIPTION OF THE REGISTERED NOTES

      The old notes were issued and the registered notes will be issued under an indenture dated as of June 25, 2003, among the Issuer, Arch Western, the Subsidiary Guarantors and The Bank of New York, as trustee, which has been filed as an exhibit to the registration statement of which this prospectus is part. Upon the effectiveness of the registration statement relating to the exchange offer, the Indenture will be subject to and governed by the Trust Indenture Act of 1939. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Security Documents referred to below under the heading “Security” define the terms of the security interest that will secure the Notes.

      On June 25, 2003, we issued $700.0 million aggregate principal amount of old notes under the Indenture. The terms of the registered notes are identical in all material respects to the old notes, except for certain transfer restrictions and registration and other rights relating to the exchange of the old notes for registered notes. The trustee will authenticate and deliver registered notes for original issue only in exchange for a like principal amount of old notes. Any old notes that remain outstanding after the consummation of the exchange offer, together with the registered notes, will be treated as a single class of securities under the Indenture. Accordingly, all references herein to specified percentages in aggregate principal amount of outstanding Notes shall be deemed to mean, at any time after the exchange offer is consummated, such percentage in aggregate principal amount of the old notes and registered notes then outstanding.

      You can find the definitions of certain terms used in this description under the subheading “Certain Definitions.” In this description, “Arch Western” refers only to Arch Western Resources, LLC and not to any of its subsidiaries, the “Issuer” refers to Arch Western Finance, LLC, a wholly owned Subsidiary of Arch Western, and “Arch Coal” refers to Arch Coal, Inc. and not to any of its subsidiaries.

      You are encouraged to read the Indenture, the Security Documents and the Registration Rights Agreement filed as exhibits to the registration statement of which this prospectus is a part and referred to under the heading “Exchange Offer; Registration Rights” because they, and not this description, define your rights as a holder of Notes. Copies of the Indenture, the Security Documents and the Registration Rights Agreement are available upon request to Arch Western at the address indicated under “Where You Can Find More Information.”

Principal, Maturity and Interest

      The Issuer may issue up to $700.0 million aggregate principal amount of registered notes in this exchange offer and, subject to compliance with the limitations described under “— Certain Covenants — Limitation on Debt,” may in the future issue an unlimited principal amount of additional notes at later dates under the same Indenture (the “Additional Notes”). Any Additional Notes that the Issuer issues in the future will be identical in all material respects to the Notes that the Issuer has issued and will issue in this exchange offer and will form a single series with such Notes, except that Additional Notes issued in the future will have different issuance dates and may have different issuance prices. The Issuer will issue registered notes only in fully registered form without coupons, in denominations of $1,000 and integral multiples of $1,000.

      The Notes will mature on July 1, 2013.

      Interest on the Notes will accrue at a rate of 6.75% per annum and will be payable semi-annually in arrears on January 1 and July 1, commencing on January 1, 2004. The Issuer will pay interest to those persons who were holders of record on the June 15 or December 15 immediately preceding each interest payment date. Interest on the Notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

Table of Contents

      The interest rate on the Notes will increase if:

        (1) the registration statements of which this prospectus is a part is not declared effective on a timely basis;
 
        (2) the exchange offer is not consummated on a timely basis; or
 
        (3) certain other conditions are not satisfied as described under “Exchange Offer; Registration Rights.”

      Any interest payable as a result of any such increase in interest rate is referred to as “Special Interest,” and all references to interest in this description include Special Interest. You should refer to the description under the heading “Exchange Offer; Registration Rights” for a more detailed description of the circumstances under which the interest rate will increase.

Ranking

      The Notes will be:

  •  senior obligations of the Issuer and
 
  •  secured by a first-priority security interest in the Arch Coal Notes.

      The Notes will be unconditionally guaranteed on a senior basis by Arch Western and all of its Domestic Subsidiaries other than Canyon Fuel. The Guarantees will be:

  •  equal in right of payment to any future senior debt of the Guarantors;
 
  •  effectively subordinated to all future secured debt of the Guarantors to the extent of the assets securing such debt;
 
  •  senior in right of payment to any future subordinated debt of the Guarantors; and
 
  •  effectively subordinated to any existing and future liabilities of any Subsidiaries of Arch Western that are not Guarantors.

      As of the date of this prospectus, all of Arch Western’s Subsidiaries are “Restricted Subsidiaries.” However, under the circumstances described below under the caption “— Certain Covenants — Designation of Restricted and Unrestricted Subsidiaries,” Arch Western is permitted to designate certain of its Subsidiaries as “Unrestricted Subsidiaries.” Arch Western’s Unrestricted Subsidiaries will not be subject to many of the restrictive covenants in the Indenture. Arch Western’s Unrestricted Subsidiaries will not Guarantee the Notes.

      In addition, as of the date of this prospectus, there are no Foreign Subsidiaries, and the only Subsidiary of Arch Western that will not Guarantee the Notes is Canyon Fuel. In the event of a bankruptcy, liquidation or reorganization of any of these non-guarantor Subsidiaries, the non-guarantor Subsidiaries will pay the holders of their debt and their trade creditors before they will be able to distribute any of their assets to Arch Western or a Subsidiary Guarantor. Arch Western’s equity interest in Canyon Fuel represented 11% of the consolidated assets of Arch Western and its subsidiaries at March 31, 2003 and contributed 2% of the total revenues of Arch Western and its subsidiaries in 2002.

Note Guarantees

     The Arch Western Guarantee

      Arch Western will unconditionally guarantee (the “Arch Western Guarantee”) all of the Issuer’s obligations under the Notes, including its obligations to pay principal, interest, and premium, if any, with respect to the Notes. The Arch Western Guarantee will be joint and several with any other Note Guarantee, will be a general unsecured obligation of Arch Western and will rank pari passu with all existing and future Debt of Arch Western that is not, by its terms, expressly subordinated in right of payment of the Arch Western Guarantee.

54


Table of Contents

     The Subsidiary Guarantees

      The Notes will be guaranteed by each existing Domestic Subsidiary of Arch Western (excluding Canyon Fuel) and all future Domestic Subsidiaries. The Indenture requires that each existing and future Restricted Subsidiary that is not otherwise a Guarantor that guarantees any other Indebtedness of Arch Western or any of its Restricted Subsidiaries guarantees the Notes.

      Each of the Subsidiary Guarantors will unconditionally guarantee, on a joint and several basis with all other Note Guarantees, all of the Issuer’s obligations under the Notes, including its obligations to pay principal, interest, and premium, if any, with respect to the Notes. The Subsidiary Guarantees will be general unsecured obligations of the Subsidiary Guarantors and will rank pari passu with all existing and future debt of the Subsidiary Guarantors that is not, by its terms, expressly subordinated in right of payment to the Subsidiary Guarantees. The obligations of each Guarantor are limited to the maximum amount which, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to its contribution obligations under the Indenture, will result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law. See “Risk Factors — Risks Related to the Registered Notes — Federal and state fraudulent conveyance laws may permit a court to void the registered notes and guarantees, and if that occurs, you may not recover payment on the registered notes.” Each Subsidiary Guarantor that makes a payment or distribution under a Subsidiary Guarantee will be entitled to a contribution from each other Subsidiary Guarantor in an amount pro rata, based on the net assets of each Subsidiary Guarantor determined in accordance with GAAP. Except as provided in “Certain Covenants — Limitation on Asset Sales,” Arch Western will not be restricted from selling or otherwise disposing of any of the Subsidiary Guarantors.

      The Indenture provides that:

        (i) in the event of a sale or other disposition, by way of merger, consolidation or otherwise, of all the Capital Stock of any Subsidiary Guarantor to any Person that is not an Affiliate of Arch Western, such Subsidiary Guarantor will be released and relieved of any obligations under its Subsidiary Guarantee; provided that the Net Available Cash from such sale or other disposition is applied in accordance with the applicable provisions of the Indenture. See “Certain Covenants — Limitation on Asset Sales”;
 
        (ii) upon the release or discharge of another Guarantee of a Subsidiary Guarantor that resulted in the creation of the Subsidiary Guarantee of such Subsidiary Guarantor, except a discharge or release by or as a result of payment under such other Guarantee, such Subsidiary Guarantor will be released and relieved of any obligations under its Subsidiary Guarantee; and
 
        (iii) upon the designation of any Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with the terms of the Indenture, such Subsidiary Guarantor will be released and relieved of any obligations under its Subsidiary Guarantee.

Security

      The Notes will be secured by a first-priority security interest in the Arch Coal Notes. As of March 31, 2003, there were $361.1 million of outstanding Arch Coal Notes. The outstanding amount of Arch Coal Notes will increase by the amount of any Restricted Payment to, or Permitted Investment in, Arch Coal or any of its Affiliates (other than Arch Western or its Restricted Subsidiaries) and will decrease to the extent Arch Coal repays amounts owing pursuant to the Arch Coal Notes.

      The Lien securing the Notes will be released upon (1) a satisfaction and discharge of the Indenture and (2) a legal defeasance as described under “— Defeasance.”

      Subject to the covenant described under “— Certain Covenants — Limitation on Debt,” Arch Western can Incur a Lien on the Arch Coal Notes to secure Debt under a credit facility in an aggregate

55


Table of Contents

principal amount not to exceed $100.0 million at any time outstanding, which Liens will be equal and ratable with the Liens securing the Notes. In such event, the Issuer, Arch Western, the administrative agent under such credit facility, the Trustee on behalf of the holders of the Notes and a collateral trustee (the “Collateral Trustee”) will amend the Security Documents and enter into a collateral trust agreement (the “Collateral Trust Agreement”). Pursuant to the terms of the Collateral Trust Agreement, the Collateral Trustee will be appointed as collateral agent for each of the secured parties and will hold the liens and security interests in the Arch Coal Notes granted pursuant to the Security Documents with sole authority to exercise remedies under the Security Documents. The Collateral Trustee will agree to act as mortgagee under all mortgages, beneficiary under all deeds of trust and as secured party under the applicable security agreements, to follow the instructions provided to it under the Collateral Trust Agreement and to carry out certain other duties.

      Under the Collateral Trust Agreement, the Liens securing the Notes and such credit facility may not be enforced by the holders of the Notes or the lenders under the new credit facility, except for certain limited exceptions involving payment or bankruptcy Events of Default under the Indenture (each, a “Triggering Event”). If a Triggering Event has occurred and is continuing, the actions of the Collateral Trustee will be directed by the Trustee, as directed by holders of at least a majority in principal amount of the Notes, and administrative agent under the new credit facility. All proceeds of the Arch Coal Notes will be ratably shared among all holders of the Notes and the lenders under the new credit facility, if any.

Optional Redemption

      Except as set forth in the next paragraph, the Notes will not be redeemable at the option of the Issuer prior to July 1, 2008. Starting on that date, the Issuer may redeem all or any portion of the Notes, at once or over time, after giving the required notice under the Indenture. The Notes may be redeemed at the redemption prices set forth below, plus accrued and unpaid interest to the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date). The following prices are for Notes redeemed during the 12-month period commencing on July 1 of the years set forth below, and are expressed as percentages of principal amount:

         
Redemption
Year Price


2008
    103.375%  
2009
    102.250%  
2010
    101.125%  
2011 and thereafter
    100.000%  

      In addition, at any time and from time to time, prior to July 1, 2006, the Issuer may redeem up to a maximum of 35% of the original aggregate principal amount of the Notes (calculated giving effect to any issuance of Additional Notes) with the proceeds of one or more Public Equity Offerings, at a redemption price equal to 106.750% of the principal amount thereof, plus accrued and unpaid interest to the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided, however, that after giving effect to any such redemption, at least 65% of the original aggregate principal amount of the Notes (calculated giving effect to any issuance of Additional Notes) remains outstanding (excluding Notes held by Arch Coal or any of its Subsidiaries). Any such redemption shall be made within 75 days of such Public Equity Offering upon not less than 30 nor more than 60 days’ prior notice.

Sinking Fund

      There will be no mandatory sinking fund payments for the Notes.

Repurchase at the Option of Holders Upon a Change of Control

      Upon the occurrence of a Change of Control, each holder of Notes shall have the right to require the Issuer to repurchase all or any part of such holder’s Notes pursuant to the offer described below (the “Change of Control Offer”) at a purchase price (the “Change of Control Purchase Price”) equal to 101% of the principal amount thereof, plus accrued and unpaid interest to the repurchase date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date). If the repurchase date is after a record date and on or before the relevant interest payment date, the accrued and unpaid interest, if any, will be paid to the person or entity in whose name the Note is registered at the close of business on that record date, and no additional interest will be payable to holders whose Notes shall be subject to redemption.

      Within 30 days following any Change of Control, the Issuer shall:

        (a) cause a notice of the Change of Control Offer to be sent at least once to the Dow Jones News Service or similar business news service in the United States; and
 
        (b) send, by first-class mail, with a copy to the Trustee, to each holder of Notes, at such holder’s address appearing in the Security Register, a notice stating:

        (1) that a Change of Control has occurred and a Change of Control Offer is being made pursuant to the covenant entitled “Repurchase at the Option of Holders Upon a Change of Control” and that all Notes timely tendered will be accepted for payment;
 
        (2) the Change of Control Purchase Price and the repurchase date, which shall be, subject to any contrary requirements of applicable law, a business day no earlier than 30 days nor later than 60 days from the date such notice is mailed;
 
        (3) the circumstances and relevant facts regarding the Change of Control (including information with respect to pro forma historical income, cash flow and capitalization after giving effect to the Change of Control); and
 
        (4) the procedures that holders of Notes must follow in order to tender their Notes (or portions thereof) for payment, and the procedures that holders of Notes must follow in order to withdraw an election to tender Notes (or portions thereof) for payment.

      The Issuer will not be required to make a Change of Control Offer following a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer made by the Issuer and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

      The Issuer will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this covenant, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue of such compliance.

      The Issuer and Arch Western have no present intention to engage in a transaction involving a Change of Control, although it is possible that they would decide to do so in the future. Subject to certain covenants described below, Arch Western could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a Change of Control under the Indenture, but that could increase the amount of debt outstanding at such time or otherwise affect its capital structure or credit ratings.

57


Table of Contents

      The definition of Change of Control includes a phrase relating to the sale, transfer, assignment, lease, conveyance or other disposition of “all or substantially all” the Property of Arch Western and its Restricted Subsidiaries, considered as a whole. Although there is a developing body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, if Arch Western and its Restricted Subsidiaries, considered as a whole, dispose of less than all of this Property by any of the means described above, the ability of a holder of Notes to require the Issuer to repurchase its Notes may be uncertain. In such a case, holders of the Notes may not be able to resolve this uncertainty without resorting to legal action.

      Future debt of Arch Western may contain prohibitions of certain events which would constitute a Change of Control or require such debt to be repurchased or repaid upon a Change of Control. In addition, the Issuer’s ability to pay cash to holders of Notes upon a repurchase may be limited by Arch Western’s then existing financial resources. The Issuer cannot assure you that sufficient funds will be available when necessary to make any required repurchases. The Issuer’s failure to repurchase Notes in connection with a Change of Control would result in a default under the Indenture. Such a default could, in turn, constitute a default under debt of the Guarantors. The Issuer’s obligation to make an offer to repurchase the Notes as a result of a Change of Control may be waived or modified at any time prior to the occurrence of such Change of Control with the written consent of the holders of at least a majority in aggregate principal amount of the Notes. See “— Amendments and Waivers.”

Certain Covenants

      Covenant Termination. Set forth below are summaries of certain covenants contained in the Indenture. Upon the first date that:

        (a) the Notes have Investment Grade Ratings from both Rating Agencies; and
 
        (b) no Default or Event of Default has occurred and is continuing under the Indenture,

      Arch Western and its Restricted Subsidiaries will cease to be subject to the following provisions of the Indenture:

  •  “— Limitation on Debt;”
 
  •  “— Limitation on Restricted Payments;”
 
  •  “— Limitation on Asset Sales;”
 
  •  “— Limitation on Restrictions on Distributions from Restricted Subsidiaries;”
 
  •  “— Limitation on Transactions with Affiliates;”
 
  •  clause (a)(i) and (b) of “— Limitation on Sale and Leaseback Transactions;”
 
  •  “— Designation of Restricted and Unrestricted Subsidiaries;” and
 
  •  clause (e) of the first paragraph of “— Merger, Consolidation and Sale of Property”

(collectively, the “Specified Covenants”). As a result, the Notes will be entitled to substantially less protection from and after the date of termination of the covenants.

      Limitation on Debt. The Issuer shall not Incur any Debt other than the Notes and any Additional Notes. Arch Western shall not, and shall not permit any Restricted Subsidiary to, Incur, directly or indirectly, any Debt unless, after giving effect to the application of the proceeds thereof, no Default or Event of Default would occur as a consequence of such Incurrence or be continuing following such Incurrence and either:

        (1) such Debt is Debt of Arch Western or a Subsidiary Guarantor and, after giving effect to the Incurrence of such Debt and the application of the proceeds thereof, Consolidated Interest Coverage Ratio of Arch Western would be at least 2.0 to 1.0, or

58


Table of Contents

        (2) such Debt is Permitted Debt.

        (a) Debt of the Issuer evidenced by the Notes and the Note Guarantees thereof;
 
        (b) Debt of Arch Western or a Restricted Subsidiary in respect of Capital Lease Obligations and Purchase Money Debt; provided that:

        (1) the aggregate principal amount of such Debt does not exceed the Fair Market Value (on the date of the Incurrence thereof) of the Property acquired, constructed or leased, and
 
        (2) the aggregate principal amount of all Debt Incurred and then outstanding pursuant to this clause (b) (together with all Permitted Refinancing Debt Incurred and then outstanding in respect of Debt previously Incurred pursuant to this clause (b)) does not exceed, at any one time outstanding, 5% of Consolidated Net Tangible Assets;

        (c) Debt of Arch Western owing to and held by any Restricted Subsidiary and Debt of a Restricted Subsidiary owing to and held by Arch Western or any Restricted Subsidiary; provided, however, that (1) any subsequent issue or transfer of Capital Stock or other event that results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any subsequent transfer of any such Debt (except to Arch Western or a Restricted Subsidiary) shall be deemed, in each case, to constitute the Incurrence of such Debt by the issuer thereof and (2) if a Guarantor is the obligor on such Debt, such Debt is subordinated in right of payment to the Note Guarantee of such Guarantor;
 
        (d) Debt under Interest Rate Agreements entered into by Arch Western or a Restricted Subsidiary for the purpose of managing interest rate risk in the ordinary course of the financial management of Arch Western or such Restricted Subsidiary and not for speculative purposes, provided that the obligations under such agreements are directly related to payment obligations on Debt otherwise permitted by the terms of this covenant;
 
        (e) Debt under Currency Exchange Protection Agreements entered into by Arch Western or a Restricted Subsidiary for the purpose of managing currency exchange rate risks directly related to transactions entered into by Arch Western or such Restricted Subsidiary in the ordinary course of business and not for speculative purposes;
 
        (f) Debt under Commodity Price Protection Agreements entered into by Arch Western or a Restricted Subsidiary in the ordinary course of the financial management of Arch Western or such Restricted Subsidiary and not for speculative purposes;
 
        (g) Debt in connection with one or more standby letters of credit or performance or surety bonds or completion guarantees issued by Arch Western or a Restricted Subsidiary in the ordinary course of business or pursuant to self-insurance obligations and not in connection with the borrowing of money or the obtaining of advances or credit;
 
        (h) Debt of Arch Western or a Restricted Subsidiary outstanding on the Issue Date not otherwise described in clauses (a) through (g) above;
 
        (i) other Debt of Arch Western or any Subsidiary Guarantor in an aggregate principal amount outstanding at any one time not to exceed $100.0 million;
 
        (j) Permitted Refinancing Debt Incurred in respect of Debt Incurred pursuant to clause (1) of the first paragraph of this covenant and clauses (b) and (h) above; and
 
        (k) Debt consisting of installment payment obligations to the federal government in connection with the acquisition of coal leases in the ordinary course of business and consistent with past practices.

59


Table of Contents

      Notwithstanding anything to the contrary contained in this covenant,

        (a) Arch Western shall not permit any Restricted Subsidiary that is not a Guarantor to Incur any Debt pursuant to this covenant if the proceeds thereof are used, directly or indirectly, to Refinance any Debt of any Guarantor; and
 
        (b) accrual of interest, accretion or amortization of original issue discount and the payment of interest or dividends in the form of additional Debt, will be deemed not to be an Incurrence of Debt for purposes of this covenant.

      For purposes of determining compliance with this covenant in the event that an item of Debt meets the criteria of more than one of the categories of Permitted Debt described in clauses (a) through (j) above or is entitled to be incurred pursuant to clause (1) of the first paragraph of this covenant, Arch Western shall, in its sole discretion, classify such item of Debt in any manner that complies with this covenant.

      Limitation on Restricted Payments. Arch Western shall not make, and shall not permit any Restricted Subsidiary to make, directly or indirectly, any Restricted Payment if at the time of, and after giving effect to, such proposed Restricted Payment,

        (a) a Default or Event of Default shall have occurred and be continuing;
 
        (b) Arch Western could not Incur at least $1.00 of additional Debt pursuant to clause (1) of the first paragraph of the covenant described under “— Limitation on Debt;” or
 
        (c) the aggregate amount of such Restricted Payment and all other Restricted Payments declared or made since the Issue Date (the amount of any Restricted Payment, if made other than in cash, to be based upon Fair Market Value at the time of such Restricted Payment) would exceed an amount equal to the sum of:

        (1) 50% of the aggregate amount of Consolidated Net Income of Arch Western accrued during the period (treated as one accounting period) from the beginning of the fiscal quarter during which the Issue Date occurs to the end of the most recent fiscal quarter ending at least 45 days prior to the date of such Restricted Payment (or if the aggregate amount of Consolidated Net Income of Arch Western for such period shall be a deficit, minus 100% of such deficit), plus
 
        (2) 100% of the Capital Stock Sale Proceeds, plus
 
        (3) the sum of:

        (A) the aggregate net cash proceeds received by Arch Western or any Restricted Subsidiary from the issuance or sale after the Issue Date of convertible or exchangeable Debt that has been converted into or exchanged for Capital Stock (other than Disqualified Stock) of Arch Western, and
 
        (B) the aggregate amount by which Debt (other than Subordinated Obligations) of Arch Western or any Restricted Subsidiary is reduced on Arch Western’s consolidated balance sheet on or after the Issue Date upon the conversion or exchange of any Debt issued or sold on or prior to the Issue Date that is convertible or exchangeable for Capital Stock (other than Disqualified Stock) of Arch Western,

        excluding, in the case of clause (A) or (B):

        (x) any such Debt issued or sold to Arch Western or a Subsidiary of Arch Western or an employee stock ownership plan or trust established by Arch Coal or any such Subsidiary for the benefit of their employees, and
 
        (y) the aggregate amount of any cash or other Property distributed by Arch Western or any Restricted Subsidiary upon any such conversion or exchange;

60


Table of Contents

      plus

        (4) an amount equal to the sum of:

        (A) the net reduction in Investments in any Person other than Arch Western or a Restricted Subsidiary resulting from dividends, repayments of loans or advances or other transfers of Property, in each case to Arch Western or any Restricted Subsidiary from such Person, and
 
        (B) the portion (proportionate to Arch Western’s equity interest in such Unrestricted Subsidiary) of the Fair Market Value of the net assets of an Unrestricted Subsidiary of Arch Western at the time such Unrestricted Subsidiary is designated a Restricted Subsidiary;

  provided, however, that the foregoing sum shall not exceed, in the case of any Person, the amount of Investments previously made (and treated as a Restricted Payment) by Arch Western or any Restricted Subsidiary in such Person.

      Notwithstanding the foregoing limitation, Arch Western may:

        (a) pay dividends on its Capital Stock within 60 days of the declaration thereof if, on the declaration date, such dividends could have been paid in compliance with the Indenture; provided, however, that such dividend shall be included in the calculation of the amount of Restricted Payments;
 
        (b) purchase, repurchase, redeem, legally defease, acquire or retire for value Capital Stock of Arch Western or Subordinated Obligations in exchange for, or out of the proceeds of the substantially concurrent sale of, Capital Stock of Arch Western (other than Disqualified Stock and other than Capital Stock issued or sold to a Subsidiary of Arch Coal or an employee stock ownership plan or trust established by Arch Coal or any such Subsidiary for the benefit of their employees); provided, however, that

        (1) such purchase, repurchase, redemption, legal defeasance, acquisition or retirement shall be excluded in the calculation of the amount of Restricted Payments and
 
        (2) the Capital Stock Sale Proceeds from such exchange or sale shall be excluded from the calculation pursuant to clause (c)(2) above;

        (c) purchase, repurchase, redeem, legally defease, acquire or retire for value any Subordinated Obligations in exchange for, or out of the proceeds of the substantially concurrent sale of, Permitted Refinancing Debt; provided, however, that such purchase, repurchase, redemption, legal defeasance, acquisition or retirement shall be excluded in the calculation of the amount of Restricted Payments;
 
        (d) repurchase shares of, or options to purchase shares of, common stock of Arch Western or any of its Subsidiaries from current or former officers, directors or employees of Arch Western or any of its Subsidiaries (or permitted transferees of such current or former officers, directors or employees), pursuant to the terms of agreements (including employment agreements) or plans (or amendments thereto) approved by the Board of Directors under which such individuals purchase or sell, or are granted the option to purchase or sell, shares of such common stock; provided, however, that: (1) the aggregate amount of such repurchases shall not exceed $2.5 million in any calendar year and (2) at the time of such repurchase, no other Default or Event of Default shall have occurred and be continuing (or result therefrom); provided further, however, that such repurchases shall be included in the calculation of the amount of Restricted Payments;

        (f) so long as no Default or Event of Default has occurred and is continuing, make distributions of the Preferred Return (as defined in the LLC Agreement) to the ARCO Member (as defined in the LLC Agreement) pursuant to the LLC Agreement in effect on the Issue Date; provided, however, that such distribution shall be included in the calculation of the amount of Restricted Payments; and

      Notwithstanding the prior two paragraphs, any Restricted Payment to, or Permitted Investments in, Arch Coal or any of its Affiliates (other than Arch Western or a Restricted Subsidiary) shall be in the form of a loan for cash which shall be evidenced by Arch Coal Notes that are immediately pledged to the Trustee on behalf of the holders of the Notes.

      Limitation on Liens. Arch Western shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, Incur or suffer to exist, any Lien on the Arch Coal Notes, except for the Liens securing the Notes and Additional Notes and Liens described in clause (k) of the definition of Permitted Liens.

      Arch Western shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, Incur or suffer to exist, any Lien (other than Permitted Liens) upon any of its Property (including Capital Stock of a Restricted Subsidiary), whether owned at the Issue Date or thereafter acquired, or any interest therein or any income or profits therefrom, unless it has made or will make effective provision whereby the Notes or any Note Guarantee will be secured by such Lien equally and ratably with (or, if such other Debt constitutes Subordinated Obligations, prior to) all other Debt of Arch Western or any Restricted Subsidiary secured by such Lien for so long as such other Debt is secured by such Lien.

      Limitation on Asset Sales. Arch Western shall not, and shall not permit any Restricted Subsidiary, to, directly or indirectly, sell, transfer or otherwise dispose of (including by means of a merger, consolidation or similar transaction) any shares of Capital Stock of the Issuer, Arch Western Notes or the Arch Coal Notes. Arch Western shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Sale unless:

        (a) Arch Western or such Restricted Subsidiary receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the Property subject to such Asset Sale;
 
        (b) at least 75% of the consideration paid to Arch Western or such Restricted Subsidiary in connection with such Asset Sale is in the form of cash or Cash Equivalents or the assumption by the purchaser of liabilities of Arch Western or any Restricted Subsidiary (other than contingent liabilities or liabilities that are by their terms subordinated to the Notes) as a result of which Arch Western and the Restricted Subsidiaries are no longer obligated with respect to such liabilities; and
 
        (c) Arch Western delivers an Officers’ Certificate to the Trustee certifying that such Asset Sale complies with the foregoing clauses (a) and (b).

      The Net Available Cash (or any portion thereof) from Asset Sales may be applied by Arch Western or a Restricted Subsidiary to the extent Arch Western or such Restricted Subsidiary elects (or is required by the terms of any Debt) to:

        (a) Repay any Debt of Arch Western or such Restricted Subsidiary (other than Subordinated Obligations); or
 
        (b) reinvest in Additional Assets (including by means of an Investment in Additional Assets by a Restricted Subsidiary with Net Available Cash received by Arch Western or another Restricted Subsidiary).

Table of Contents

      Any Net Available Cash from an Asset Sale (other than an Asset Sale consisting of all of the Capital Stock of Canyon Fuel or Mountain Coal Company, L.L.C.) not applied in accordance with the preceding paragraph within 365 days from the date of the receipt of such Net Available Cash or that is not segregated from the general funds of Arch Western for investment in identified Additional Assets in respect of a project that shall have been commenced, and for which binding contractual commitments have been entered into, prior to the end of such 365-day period and that shall not have been completed or abandoned shall constitute “Excess Proceeds;” provided, however, that the amount of any Net Available Cash that ceases to be so segregated as contemplated above and any Net Available Cash that is segregated in respect of a project that is abandoned or completed shall also constitute “Excess Proceeds” at the time any such Net Available Cash ceases to be so segregated or at the time the relevant project is so abandoned or completed, as applicable; provided further, however, that the amount of any Net Available Cash that continues to be segregated for investment and that is not actually reinvested within twenty-four months from the date of the receipt of such Net Available Cash shall also constitute “Excess Proceeds.” Any Net Available Cash from an Asset Sale consisting of all of the Capital Stock of Canyon Fuel or Mountain Coal Company, L.L.C. not applied in accordance with the preceding paragraph within 365 days from the date of the receipt of such Net Available Cash shall be segregated from the general funds of Arch Western and invested in cash or Cash Equivalents pending application in accordance with the preceding paragraph.

      When the aggregate amount of Excess Proceeds (including income earned on such Excess Proceeds) exceeds $20.0 million, the Issuer will be required to make an offer to repurchase (the “Prepayment Offer”) the Notes, which offer shall be in the amount of the Allocable Excess Proceeds (rounded to the nearest $1,000), on a pro rata basis according to principal amount, at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the repurchase date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), in accordance with the procedures (including prorating in the event of oversubscription) set forth in the Indenture. To the extent that any portion of the amount of Net Available Cash remains after compliance with the preceding sentence and provided that all holders of Notes have been given the opportunity to tender their Notes for repurchase in accordance with the Indenture, Arch Western or such Restricted Subsidiary may use such remaining amount for any purpose permitted by the Indenture, and the amount of Excess Proceeds will be reset to zero.

      The term “Allocable Excess Proceeds” shall mean the product of:

        (a) the Excess Proceeds and
 
        (b) a fraction,

        (1) the numerator of which is the aggregate principal amount of the Notes outstanding on the date of the Prepayment Offer, and
 
        (2) the denominator of which is the sum of the aggregate principal amount of the Notes outstanding on the date of the Prepayment Offer and the aggregate principal amount of other Debt of Arch Western outstanding on the date of the Prepayment Offer that is pari passu in right of payment with the Arch Western Guarantee and subject to terms and conditions in respect of Asset Sales similar in all material respects to this covenant and requiring Arch Western to make an offer to repurchase such Debt at substantially the same time as the Prepayment Offer.

      Within five business days after the Issuer is obligated to make a Prepayment Offer as described in the preceding paragraph, the Issuer shall send a written notice, by first-class mail, to the holders of Notes, accompanied by such information regarding Arch Western and its Subsidiaries as the Issuer in good faith believes will enable such holders to make an informed decision with respect to such Prepayment Offer. Such notice shall state, among other things, the purchase price and the repurchase date, which shall be, subject to any contrary requirements of applicable law, a business day no earlier than 30 days nor later than 60 days from the date such notice is mailed.

Table of Contents

      The Issuer will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to this covenant. To the extent that the provisions of any securities laws or regulations conflict with provisions of this covenant, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue thereof.

      Limitation on Restrictions on Distributions from Restricted Subsidiaries. Arch Western shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create or otherwise cause or suffer to exist any consensual restriction on the right of any Restricted Subsidiary to:

        (a) pay dividends, in cash or otherwise, or make any other distributions on or in respect of its Capital Stock, or pay any Debt or other obligation owed, to Arch Western or any other Restricted Subsidiary;
 
        (b) make any loans or advances to Arch Western or any other Restricted Subsidiary; or
 
        (c) transfer any of its Property to Arch Western or any other Restricted Subsidiary.
 
        The foregoing limitations will not apply:

        (1) with respect to clauses (a), (b) and (c), to restrictions:

        (A) in effect on the Issue Date (including, without limitation, restrictions pursuant to the Notes and the Indenture);
 
        (B) relating to Debt of a Restricted Subsidiary of Arch Western and existing at the time it became a Restricted Subsidiary if such restriction was not created in connection with or in anticipation of the transaction or series of transactions pursuant to which such Restricted Subsidiary became a Restricted Subsidiary or was acquired by Arch Western; or
 
        (C) that result from any amendment, restatement, renewal or replacement of an agreement referred to in clause (1)(A) or (B) above or in clause (2)(A) or (B) below, provided such restrictions are not less favorable, taken as a whole, to the holders of Notes than those under the agreement evidencing the Debt so Refinanced, and

        (2) with respect to clause (c) only, to restrictions:

        (A) relating to Debt that is permitted to be Incurred and secured without also securing the Notes pursuant to the covenants described under “— Limitation on Debt” and “— Limitation on Liens” that limit the right of the debtor to dispose of the Property securing such Debt;
 
        (B) encumbering Property at the time such Property was acquired by Arch Western or any of its Restricted Subsidiaries, so long as such restrictions relate solely to the Property so acquired and were not created in connection with or in anticipation of such acquisition;
 
        (C) resulting from customary provisions restricting subletting or assignment of leases or customary provisions in other agreements that restrict assignment of such agreements or rights thereunder; or
 
        (D) customary restrictions contained in asset sale agreements limiting the transfer of such Property pending the closing of such sale.

      Limitation on Transactions with Affiliates. Arch Western shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, conduct any business or enter into or suffer to exist any transaction or series of transactions (including the purchase, sale, transfer, assignment, lease, conveyance

or exchange of any Property or the rendering of any service) with, or for the benefit of, any Affiliate of Arch Western (an “Affiliate Transaction”), unless:

        (a) the terms of such Affiliate Transaction are:

        (1) set forth in writing;
 
        (2) in the best interest of Arch Western or such Restricted Subsidiary, as the case may be; and
 
        (3) no less favorable to Arch Western or such Restricted Subsidiary, as the case may be, than those that could be obtained in a comparable arm’s-length transaction with a Person that is not an Affiliate of Arch Western;

        (b) if such Affiliate Transaction involves aggregate payments or value in excess of $5.0 million, the Board of Directors (including at least a majority of the disinterested members of the Board of Directors) approves such Affiliate Transaction and, in its good faith judgment, believes that such Affiliate Transaction complies with clauses (a)(2) and (3) of this paragraph as evidenced by a Board Resolution promptly delivered to the Trustee; provided, however, if there are no disinterested members of the Board of Directors, Arch Western shall receive a written opinion from an Independent Financial Advisor described in clause (c) below; and
 
        (c) if such Affiliate Transaction involves aggregate payments or value in excess of $25.0 million, Arch Western obtains a written opinion from an Independent Financial Advisor to the effect that the consideration to be paid or received in connection with such Affiliate Transaction is fair, from a financial point of view, to Arch Western and its Restricted Subsidiaries.

      Notwithstanding the foregoing limitation, Arch Western or any Restricted Subsidiary may enter into or suffer to exist the following:

        (a) any transaction or series of transactions between Arch Western and one or more Restricted Subsidiaries or between two or more Restricted Subsidiaries in the ordinary course of business, provided that no more than 5% of the total voting power of the Voting Stock (on a fully diluted basis) of any such Restricted Subsidiary is owned by an Affiliate of Arch Western (other than a Restricted Subsidiary);
 
        (b) any Restricted Payment (other than an Investment) permitted to be made pursuant to the first paragraph of the covenant described under “— Limitation on Restricted Payments;”
 
        (c) the payment of compensation (including amounts paid pursuant to employee benefit plans) for the personal services of officers, directors and employees of Arch Western or any of its Restricted Subsidiaries, so long as the Board of Directors in good faith shall have approved the terms thereof and deemed the services theretofore or thereafter to be performed for such compensation to be fair consideration therefor;
 
        (d) loans and advances to employees made in the ordinary course of business permitted by law and consistent with the past practices of Arch Western or such Restricted Subsidiary, as the case may be, provided that such loans and advances do not exceed $2.5 million in the aggregate at any one time outstanding;
 
        (e) agreements in effect on the Issue Date and described in this prospectus and any modifications, extensions or renewals thereto that are no less favorable to Arch Western or any Restricted Subsidiary than such agreements as in effect on the Issue Date; and

      Limitation on Sale and Leaseback Transactions. Arch Western shall not, and shall not permit any of its Restricted Subsidies to, enter into any Sale and Leaseback Transaction with respect to any Property unless:

        (a) Arch Western or such Restricted Subsidiary would be entitled to:

        (1) Incur Debt in an amount equal to the Attributable Debt with respect to such Sale and Leaseback Transaction pursuant to the covenant described under “— Limitation on Debt;” and
 
        (2) create a Lien on such Property securing such Attributable Debt without also securing the Notes or the applicable Note Guarantee pursuant to the covenant described under “— Limitation on Liens;” and

        (b) such Sale and Leaseback Transaction is effected in compliance with the covenant described under “— Limitation on Asset Sales.”

      Designation of Restricted and Unrestricted Subsidiaries. The Board of Directors may designate any Restricted Subsidiary (other than the Issuer) to be an Unrestricted Subsidiary if that designation (which would constitute an Investment in such Subsidiary) would not result in a breach of the covenant described under “— Limitation on Restricted Payments” or otherwise cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by Arch Western and its Restricted Subsidiaries in the Subsidiary properly designated will be deemed to be an Investment made as of the time of the designation as set forth under the definition of “Investment” and will reduce the amount available for Restricted Payments under the first paragraph of the “— Limitation on Restricted Payments” covenant or Permitted Investments, as determined by Arch Western. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

      The Board of Directors may also designate any Subsidiary of Arch Western to be an Unrestricted Subsidiary if:

        (a) the Subsidiary to be so designated does not own any Capital Stock or Debt of, or own or hold any Lien on any Property of, Arch Western or any other Restricted Subsidiary and is not required to be a Guarantor pursuant to the Indenture; and
 
        (b) either:

        (1) the Subsidiary to be so designated has total assets of $1,000 or less; or
 
        (2) such designation is effective immediately upon such entity becoming a Subsidiary of Arch Western.

      Unless so designated as an Unrestricted Subsidiary, any Person that becomes a Subsidiary of Arch Western will be classified as a Restricted Subsidiary; provided, however, that such Subsidiary shall not be designated a Restricted Subsidiary and shall be automatically classified as an Unrestricted Subsidiary if either of the requirements set forth in clauses (x) and (y) of the second immediately following paragraph will not be satisfied after giving pro forma effect to such classification or if such Person is a Subsidiary of an Unrestricted Subsidiary.

      In addition, neither Arch Western nor any of its Restricted Subsidiaries shall at any time be directly or indirectly liable for any Debt that provides that the holder thereof may (with the passage of time or notice or both) declare a default thereon or cause the payment thereof to be accelerated or payable prior to its Stated Maturity upon the occurrence of a default with respect to any Debt, Lien or other obligation of any Unrestricted Subsidiary (including any right to take enforcement action against such Unrestricted Subsidiary).

66


Table of Contents

      The Board of Directors may designate any Unrestricted Subsidiary to be a Restricted Subsidiary if, immediately after giving pro forma effect to such designation,

        (x) Arch Western could Incur at least $1.00 of additional Debt pursuant to clause (1) of the first paragraph of the covenant described under “— Limitation on Debt,” and
 
        (y) no Default or Event of Default shall have occurred and be continuing or would result therefrom.

      Any such designation or redesignation by the Board of Directors will be evidenced by filing with the Trustee a Board Resolution giving effect to such designation or redesignation and an Officers’ Certificate that:

        (a) certifies that such designation or redesignation complies with the foregoing provisions; and
 
        (b) gives the effective date of such designation or redesignation,

such filing with the Trustee to occur within 45 days after the end of the fiscal quarter of Arch Western in which such designation or redesignation is made (or, in the case of a designation or redesignation made during the last fiscal quarter of Arch Western’s fiscal year, within 90 days after the end of such fiscal year).

      Guarantees by Restricted Subsidiaries. Arch Western shall not permit any Restricted Subsidiary that is not a Guarantor, directly or indirectly, to Guarantee or secure the payment of any other Debt of Arch Western or any of its Restricted Subsidiaries unless such Restricted Subsidiary simultaneously executes and delivers a supplemental indenture to the Indenture providing for a Subsidiary Guarantee of the payment of the Notes by such Restricted Subsidiary; provided that this paragraph shall not be applicable to:

        (i) any Guarantee of any Restricted Subsidiary that existed at the time such Person became a Restricted Subsidiary and was not incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary;
 
        (ii) any Guarantee arising under or in connection with performance bonds, indemnity bonds, surety bonds or letters of credit or bankers’ acceptances; or
 
        (iii) Permitted Liens.

      If the Guaranteed Debt is a Subordinated Obligation, the Guarantee of such Guaranteed Debt must be subordinated in right of payment to the Subsidiary Guarantee to at least the extent that the Guaranteed Debt is subordinated to the Notes or the applicable Subsidiary Guarantee.

Merger, Consolidation and Sale of Property

      The Issuer shall not merge, consolidate or amalgamate with or into any other Person. Arch Western shall not merge, consolidate or amalgamate with or into any other Person (other than a merger of a Wholly Owned Restricted Subsidiary of Arch Western into Arch Western) or sell, transfer, assign, lease, convey or otherwise dispose of all or substantially all its Property in any one transaction or series of transactions unless:

        (a) Arch Western is the Surviving Person or the Surviving Person (if other than Arch Western) formed by such merger, consolidation or amalgamation or to which such sale, transfer, assignment, lease, conveyance or disposition is made shall be a limited liability company or corporation organized and existing under the laws of the United States of America, any state thereof or the District of Columbia;
 
        (b) the Surviving Person (if other than Arch Western) expressly assumes, by supplemental indenture in form satisfactory to the Trustee, executed and delivered to the Trustee by such Surviving Person, the due and punctual performance and observance of all the obligations of the Indenture, the Arch Western Guarantee or the Security Documents, to be performed by Arch Western;

        (d) immediately before and after giving effect to such transaction or series of transactions on a pro forma basis (and treating, for purposes of this clause (d) and clause (e) below, any Debt that becomes, or is anticipated to become, an obligation of the Surviving Person or any Restricted Subsidiary as a result of such transaction or series of transactions as having been Incurred by the Surviving Person or such Restricted Subsidiary at the time of such transaction or series of transactions), no Default or Event of Default shall have occurred and be continuing;
 
        (e) immediately after giving effect to such transaction or series of transactions on a pro forma basis, at least $1.00 of additional Debt would be able to be Incurred under clause (1) of the first paragraph of the covenant described under “— Certain Covenants — Limitation on Debt;”
 
        (f) Arch Western shall deliver, or cause to be delivered, to the Trustee, in form and substance reasonably satisfactory to the Trustee, an Officers’ Certificate and an Opinion of Counsel, each stating that such transaction or series of transactions and the supplemental indenture, if any, in respect thereto comply with this covenant and that all conditions precedent herein provided for relating to such transaction or series of transactions have been satisfied; and
 
        (g) Arch Western shall have delivered to the Trustee an Opinion of Counsel to the effect that the holders will not recognize income, gain or loss for Federal income tax purposes as a result of such transaction and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such transaction had not occurred.

      Arch Western shall not permit any Subsidiary Guarantor to consolidate with or merge with or into any Person or sell, assign, transfer, convey or otherwise dispose of, all or substantially all of its assets, in one or more related transactions, to any Person unless Arch Western has delivered to the Trustee an Officers’ Certificate and Opinion of Counsel stating that the transaction complies with the following conditions and each of the following conditions is satisfied:

        (a) the other Person is Arch Western or any Wholly Owned Restricted Subsidiary that is a Subsidiary Guarantor or becomes a Subsidiary Guarantor concurrently with the transaction; or
 
        (b) (1) either (x) the Subsidiary Guarantor shall be the Surviving Person or (y) the entity formed by such consolidation or into which the Subsidiary Guarantor is merged, expressly assumes, by a Guarantee or a supplemental indenture in form satisfactory to the Trustee, executed and delivered to the Trustee by such surviving Person the due and punctual performance and observance of all the obligations of such Subsidiary Guarantor under the Subsidiary Guarantee; and

        (2) the Surviving Person, if other than the Subsidiary Guarantor, is a corporation or limited liability company organized under the laws of the United States, any state thereof or the District of Columbia and immediately after giving effect to the transaction and any related Incurrence of Debt of, no Default or Event of Default shall have occurred and be continuing; or

        (c) the transaction constitutes a sale or other disposition (including by way of consolidation or merger) of the Subsidiary Guarantor or the sale or disposition of all or substantially all the assets of the Subsidiary Guarantor (in each case other than to another Subsidiary Guarantor) and at the time of such transaction after giving pro forma effect thereto, the provisions of clause (d) of the first paragraph of this covenant would be satisfied, the transaction is otherwise permitted by the Indenture and the Subsidiary Guarantor is released from its Subsidiary Guarantee at the time of such transaction in accordance with the Indenture.

Events of Default

      Events of Default in respect of the Notes include:

        (1) failure to make the payment of any interest on the Notes when the same becomes due and payable, and such failure continues for a period of 30 days;
 
        (2) failure to make the payment of any principal of, or premium, if any, on, any of the Notes when the same becomes due and payable at its Stated Maturity, upon acceleration, redemption, optional redemption, required repurchase or otherwise;
 
        (3) failure to comply with the covenant described under “— Repurchase at the Option of Holders Upon a Change of Control,” “— Certain Covenants — Limitations on Asset Sales” and “— Merger, Consolidation and Sale of Property;”

69


Table of Contents

        (6) any judgment or judgments for the payment of money in an aggregate amount in excess of $25.0 million (or its foreign currency equivalent at the time) that shall be rendered against Arch Western or any Restricted Subsidiary and that shall not be waived, satisfied or discharged for any period of 30 consecutive days during which a stay of enforcement shall not be in effect (the “judgment default provisions”);
 
        (7) certain events involving bankruptcy, insolvency or reorganization of Arch Coal, Arch Western, the Issuer, any Guarantor or any other Significant Subsidiary (the “bankruptcy provisions”);
 
        (8) any Note Guarantee shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, shall deny or disaffirm its obligations under any Note Guarantee; and
 
        (9) the legal impairment of the security interests under the Security Documents for any reason other than the satisfaction in full of all obligations under the Indenture and discharge of the Security Documents or any security interest created thereunder shall be declared invalid or unenforceable or Arch Western or any of its Subsidiaries asserting, in any pleading in any court of competent jurisdiction, that any such security interest is invalid or unenforceable (the “security default provisions”).

      A Default under clause (4) is not an Event of Default until the Trustee or the holders of not less than 25% in aggregate principal amount of the Notes then outstanding notify Arch Western or the Issuer of the Default and Arch Western or the Issuer does not cure such Default within the time specified after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.”

      Arch Western shall deliver to the Trustee, within 30 days after the occurrence thereof, written notice in the form of an Officers’ Certificate of any event that with the giving of notice or the lapse of time or both would become an Event of Default, its status and what action is being taken or proposed to be taken with respect thereto.

      If an Event of Default with respect to the Notes (other than an Event of Default resulting from the bankruptcy provisions) shall have occurred and be continuing, the Trustee or the registered holders of not less than 25% in aggregate principal amount of the Notes then outstanding may declare to be immediately due and payable the principal amount of all the Notes then outstanding, plus accrued but unpaid interest to the date of acceleration. In case an Event of Default resulting the bankruptcy provisions shall occur, such amount with respect to all the Notes shall be due and payable immediately without any declaration or other act on the part of the Trustee or the holders of the Notes. After any such acceleration, but before a judgment or decree based on acceleration is obtained by the Trustee, the registered holders of at least a majority in aggregate principal amount of the Notes then outstanding may, under certain circumstances, rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal, premium or interest, have been cured or waived as provided in the Indenture.

      Subject to the provisions of the Indenture relating to the duties of the Trustee, in case an Event of Default shall occur and be continuing, the Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request or direction of any of the holders of the Notes, unless such holders shall have offered to the Trustee reasonable indemnity. Subject to such provisions for the indemnification of the Trustee, the holders of at least a majority in aggregate principal amount of the Notes then outstanding will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Notes.

      No holder of Notes will have any right to institute any proceeding with respect to the Indenture, or for the appointment of a receiver or trustee, or for any remedy thereunder, unless:

        (a) such holder has previously given to the Trustee written notice of a continuing Event of Default;

      The Indenture and the Notes may be amended by Arch Western, the Issuer and the Trustee without the consent of any holder of the Notes to:

        (a) cure any ambiguity, omission, defect or inconsistency in any manner that is not adverse in any material respect to any holder of the Notes;
 
        (b) provide for the assumption by a Surviving Person of the obligations of Arch Western under the Indenture;
 
        (c) provide for uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code);
 
        (d) add Note Guarantees with respect to the Notes or confirm and evidence the release, termination or discharge of any security or Note Guarantee when such release, termination or discharge is permitted by the Indenture;

        (h) provide for the issuance of Additional Notes in accordance with the Indenture.

      The consent of the holders of the Notes is not necessary to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment. After an amendment becomes effective, the Issuer is required to mail to each registered holder of the Notes at such holder’s address appearing in the Security Register a notice briefly describing such amendment. However, the failure to give such notice to all holders of the Notes, or any defect therein, will not impair or affect the validity of the amendment.

Defeasance

      Arch Western and the Issuer at any time may terminate all of their obligations under the Notes and the Indenture (“legal defeasance”), except for certain obligations, including those respecting the defeasance trust and obligations to register the transfer or exchange of the Notes, to replace mutilated, destroyed, lost or stolen Notes and to maintain a registrar and paying agent in respect of the Notes. Arch Western and the Issuer at any time may terminate:

        (1) their obligations under the covenants described under “— Repurchase at the Option of Holders Upon a Change of Control” and “— Certain Covenants;”

Arch Western and the Issuer may exercise their legal defeasance option notwithstanding their prior exercise of its covenant defeasance option.

      If Arch Western and the Issuer exercise their legal defeasance option, payment of the Notes may not be accelerated because of an Event of Default with respect thereto. If Arch Western and the Issuer exercise their covenant defeasance option, payment of the Notes may not be accelerated because of an Event of Default specified in clause (4) (with respect to the covenants described under “— Certain

72


Table of Contents

Covenants”), (5), (6) or (7) (with respect only to Significant Subsidiaries) under “— Events of Default” above or because of the failure to comply with clause (e) under the first paragraph of “— Merger, Consolidation and Sale of Property” above.

      The legal defeasance option or the covenant defeasance option may be exercised only if:

        (a) Arch Western or the Issuer irrevocably deposit in trust with the Trustee money or U.S. Government Obligations for the payment of principal of, premium, if any, and interest on the Notes to maturity or redemption, as the case may be;
 
        (b) Arch Western or the Issuer delivers to the Trustee a certificate from a nationally recognized firm of independent certified public accountants expressing their opinion that the payments of principal, premium, if any, and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal, premium, if any, and interest when due on all the Notes to be defeased to maturity or redemption, as the case may be;
 
        (c) 123 days pass after the deposit is made, and during the 123-day period, no Default described in clause (7) under “— Events of Default” occurs with respect to Arch Western or the Issuer or any other Person making such deposit which is continuing at the end of the period;
 
        (d) no Default or Event of Default has occurred and is continuing on the date of such deposit and after giving effect thereto;
 
        (e) such deposit does not constitute a default under any other agreement or instrument binding on Arch Western or any of its Restricted Subsidiaries;
 
        (f) Arch Western or the Issuer delivers to the Trustee an Opinion of Counsel to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940;
 
        (g) in the case of the legal defeasance option, Arch Western or the Issuer delivers to the Trustee an Opinion of Counsel stating that:

        (1) Arch Western or the Issuer has received from the Internal Revenue Service a ruling, or
 
        (2) since the date of the Indenture there has been a change in the applicable Federal income tax law, to the effect that, and based thereon such Opinion of Counsel shall confirm that, the holders of the Notes will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same time as would have been the case if such defeasance has not occurred;

        (h) in the case of the covenant defeasance option, Arch Western or the Issuer delivers to the Trustee an Opinion of Counsel to the effect that the holders of the Notes will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred; and
 
        (i) Arch Western or the Issuer delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Notes have been complied with as required by the Indenture.

Book-Entry System

      The Notes will be initially issued in the form of one or more Global Securities registered in the name of The Depository Trust Company (“DTC”) or its nominee.

      Upon the issuance of a Global Security, DTC or its nominee will credit the accounts of Persons holding through it with the respective principal amounts of the Notes represented by such Global Security purchased by such Persons in the offering. Such accounts shall be designated by the initial purchasers. Ownership of beneficial interests in a Global Security will be limited to Persons that have accounts with DTC (“participants”) or Persons that may hold interests through participants. Any Person acquiring an interest in a Global Security through an offshore transaction in reliance on Regulation S of the Securities Act may hold such interest through Clearstream Banking, S.A. or Euroclear Bank S.A./ N.V., as operator of the Euroclear System. Ownership of beneficial interests in a Global Security will be shown on, and the transfer of that ownership interest will be effected only through, records maintained by DTC (with respect to participants’ interests) and such participants (with respect to the owners of beneficial interests in such Global Security other than participants). The laws of some jurisdictions require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and such laws may impair the ability to transfer beneficial interests in a Global Security.

      Payment of principal of and interest on Notes represented by a Global Security will be made in immediately available funds to DTC or its nominee, as the case may be, as the sole registered owner and the sole holder of the Notes represented thereby for all purposes under the Indenture. Arch Western has been advised by DTC that upon receipt of any payment of principal of or interest on any Global Security, DTC will immediately credit, on its book-entry registration and transfer system, the accounts of participants with payments in amounts proportionate to their respective beneficial interests in the principal or face amount of such Global Security as shown on the records of DTC. Payments by participants to owners of beneficial interests in a Global Security held through such participants will be governed by standing instructions and customary practices as is now the case with securities held for customer accounts registered in “street name” and will be the sole responsibility of such participants.

      A Global Security may not be transferred except as a whole by DTC or a nominee of DTC to a nominee of DTC or to DTC. A Global Security is exchangeable for certificated Notes only if:

        (a) DTC notifies Arch Western that it is unwilling or unable to continue as a depositary for such Global Security or if at any time DTC ceases to be a clearing agency registered under the Exchange Act;
 
        (b) Arch Western in its discretion at any time determines not to have all the Notes represented by such Global Security; or
 
        (c) there shall have occurred and be continuing a Default or an Event of Default with respect to the Notes represented by such Global Security.

      Any Global Security that is exchangeable for certificated Notes pursuant to the preceding sentence will be exchanged for certificated Notes in authorized denominations and registered in such names as DTC or any successor depositary holding such Global Security may direct. Subject to the foregoing, a Global Security is not exchangeable, except for a Global Security of like denomination to be registered in the

91


Table of Contents

name of DTC or any successor depositary or its nominee. In the event that a Global Security becomes exchangeable for certificated Notes,

        (1) certificated Notes will be issued only in fully registered form in denominations of $1,000 or integral multiples thereof;
 
        (2) payment of principal of, and premium, if any, and interest on, the certificated Notes will be payable, and the transfer of the certificated Notes will be registrable, at the office or agency of Arch Western maintained for such purposes; and
 
        (3) no service charge will be made for any registration of transfer or exchange of the certificated Notes, although Arch Western may require payment of a sum sufficient to cover any tax or governmental charge imposed in connection therewith.

      So long as DTC or any successor depositary for a Global Security, or any nominee, is the registered owner of such Global Security, DTC or such successor depositary or nominee, as the case may be, will be considered the sole owner or holder of the Notes represented by such Global Security for all purposes under the Indenture and the Notes. Except as set forth above, owners of beneficial interests in a Global Security will not be entitled to have the Notes represented by such Global Security registered in their names, will not receive or be entitled to receive physical delivery of certificated Notes in definitive form and will not be considered to be the owners or holders of any Notes under such Global Security. Accordingly, each Person owning a beneficial interest in a Global Security must rely on the procedures of DTC or any successor depositary, and, if such Person is not a participant, on the procedures of the participant through which such Person owns its interest, to exercise any rights of a holder under the Indenture. Arch Western and the Issuer understand that under existing industry practices, in the event that requests any action of holders are requested or that an owner of a beneficial interest in a Global Security desires to give or take any action which a holder is entitled to give or take under the Indenture, DTC or any successor depositary would authorize the participants holding the relevant beneficial interest to give or take such action and such participants would authorize beneficial owners owning through such participants to give or take such action or would otherwise act upon the instructions of beneficial owners owning through them.

      DTC has advised Arch Western and the Issuer that DTC is a limited-purpose trust company organized under the Banking Law of the State of New York, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered under the Exchange Act. DTC was created to hold the securities of its participants and to facilitate the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. DTC’s participants include securities brokers and dealers (which may include the initial purchasers), banks, trust companies, clearing corporations and certain other organizations some of whom (or their representatives) own DTC. Access to DTC’s book-entry system is also available to others, such as banks, brokers, dealers and trust companies, that clear through or maintain a custodial relationship with a participant, either directly or indirectly.

      Although DTC has agreed to the foregoing procedures in order to facilitate transfers of interests in Global Securities among participants of DTC, it is under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. None of Arch Western, the Issuer or the Trustee will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

EXCHANGE OFFER; REGISTRATION RIGHTS

      The Issuer, Arch Western, Arch Coal and the subsidiary guarantors have agreed pursuant to a registration rights agreement (the “Registration Rights Agreement”) with the initial purchasers of the old notes, for the benefit of the holders of the old notes, that the Issuer, Arch Western, Arch Coal and the subsidiary guarantors will, at their cost, use their reasonable best efforts to cause the registration statement of which this prospectus is part to be declared effective under the Securities Act not later than 180 days after the date of original issuance of the old notes. Upon the effectiveness of the registration statement of which this prospectus is part, the Issuer will offer the registered notes in exchange for surrender of the old notes (the “Registered Exchange Offer”). The Issuer will keep the Registered Exchange Offer open for not less than 30 days and not more than 45 days after the date notice of the Registered Exchange Offer is mailed to the holders of the old notes (or in each case, longer if required by applicable law). For each old note surrendered to the Issuer pursuant to the Registered Exchange Offer, the holder of such old note will receive an registered note having a principal amount equal to that of the surrendered old note. Interest on each registered note will accrue from the last interest payment date on which interest was paid on the old note surrendered in exchange thereof or, if no interest has been paid on such old note, from the date of the original issue of the surrendered old note. Under existing SEC interpretations, the registered notes would be freely transferable by holders of the old notes other than affiliates of the Issuer after the Registered Exchange Offer without further registration under the Securities Act if the holder of the registered notes represents that it is acquiring the registered notes in the ordinary course of its business, that it is not engaging in and does not intend to engage in a distribution of the registered note, that it has no arrangement or understanding with any person to participate in the distribution of the registered notes and that it is not an affiliate of the Issuer, as such terms are interpreted by the SEC, provided that broker-dealers (“Participating Broker-Dealers”) receiving registered notes in the Registered Exchange Offer will have a prospectus delivery requirement with respect to resales of such registered notes. The SEC has taken the position that Participating Broker-Dealers may fulfill their prospectus delivery requirements with respect to registered notes (other than a resale of an unsold allotment from the original sale of the old notes) with the prospectus contained in the registration statement of which this prospectus is part. Under the Registration Rights Agreement, the Issuer, Arch Western, Arch Coal and the subsidiary guarantors will be required to allow Participating Broker-Dealers and other persons, if any, with similar prospectus delivery requirements to use this prospectus in connection with the resale of such registered notes for 180 days following the effective date of the registration statement of which this prospectus is part (or such shorter period during which Participating Broker-Dealers are required by law to deliver this prospectus).

      A holder of old notes (other than certain specified holders) who wishes to exchange such old notes for registered notes in the Registered Exchange Offer will be required to represent that any registered notes to be received by it will be acquired in the ordinary course of its business and that at the time of the commencement of the Registered Exchange Offer it has no arrangement or understanding with any person to participate in the distribution (within the meaning of the Securities Act) of the registered notes and that it is not an “affiliate” of the Issuer, as defined in Rule 405 of the Securities Act, or if it is an affiliate, that it will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable.

      In the event that (i) due to any change in law or applicable interpretations of the SEC’s staff, we determine upon advise of our outside counsel that we are not permitted to effect the Registered Exchange Offer; (ii) for any other reason the Registered Exchange Offer is not consummated within 225 days after the date of the original issuance of the old notes; (iii) any initial purchaser so requests with respect to old notes not eligible to be exchanged for registered notes in the Registered Exchange Offer that are held by that initial purchaser following consummation of the Registered Exchange Offer; (iv) any holder of old notes (other than an initial purchaser) is not eligible to participate in the Registered Exchange Offer; or (v) any initial purchaser of old notes that participates in the Registered Exchange Offer does not receive freely tradeable registered notes in the exchange offer in exchange for old notes constituting any portion of an unsold allotment (it being understood that (x) the requirement that an initial purchaser of old notes deliver this prospectus in connection with sales of registered notes acquired in exchange for old notes shall

result in such registered notes being not “freely tradeable” and (y) the requirement that a Participating Broker-Dealer deliver this prospectus in connection with sales of registered notes acquired in the Registered Exchange Offer shall not result in such registered notes being not “freely tradeable”), the Issuer, Arch Western, Arch Coal and the subsidiary guarantors will, at their cost, (a) as promptly as practicable, but in no event later than 60 days after such filing obligation arises, file a shelf registration statement (the “Shelf Registration Statement”) covering resales of the old notes or the registered notes, as the case may be; (b) use their reasonable best efforts to cause the Shelf Registration Statement to be declared effective under the Securities Act; and (c) use their reasonable best efforts to keep the Shelf Registration Statement continuously effective, supplemented and amended as required by the Securities Act, in order to permit the prospectus forming part of the Shelf Registration Statement to be usable for a period of two years from the date the Shelf Registration Statement is declared effective by the SEC or such shorter period that will terminate when all securities covered by the Shelf Registration Statement have been sold pursuant to the Shelf Registration Statement. The Issuer will, in the event a Shelf Registration Statement is filed, among other things, provide to each holder for whom such Shelf Registration Statement was filed copies of the prospectus which is a part of the Shelf Registration Statement, notify each such holder when the Shelf Registration Statement has become effective and take certain other actions as are required to permit unrestricted resales of the old notes or the registered notes, as the case may be. A holder selling such old notes or registered notes pursuant to the Shelf Registration Statement generally would be required to be named as a selling security holder in the related prospectus and to deliver a prospectus to purchasers, will be subject to certain of the civil liability provisions under the Securities Act in connection with such sales and will be bound by the provisions of the Registration Rights Agreement which are applicable to such holder (including certain indemnification obligations).

      If (a) on or prior to the 180th day following the date of original issuance of the old notes, the registration statement of which this prospectus is part has not been declared effective by the SEC; (b) on or prior to the 225th day following the date of original issuance of the old notes the Registered Exchange Offer has not been consummated; (c) on or prior to the 60th day following the date the obligation to file the Shelf Registration Statement arises, the Shelf Registration Statement has not been filed with the SEC; (d) on or prior to 180th day following the date the obligation to file arises, the Shelf Registration has not been declared effective; or (e) after either the registration statement of which this prospectus is part or the Shelf Registration Statement has been declared effective, such Registration Statement thereafter ceases to be effective or usable (subject to certain exceptions) in connection with resales of old notes or registered notes in accordance with and during the periods specified in the Registration Rights Agreement (each such event referred to in clauses (a) through (d), a “Registration Default”), interest (“Special Interest”) will accrue on the principal amount of the old notes and the registered notes (in addition to the stated interest on the old notes and the registered notes) from and including the date on which any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured. Special Interest will accrue at a rate of 0.25% per annum during the 90-day period immediately following the occurrence of such Registration Default and shall increase by 0.25% per annum at the end of each subsequent 90-day period, but in no event shall such rate exceed 1.00% per annum.

      The summary herein of certain registration provisions does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all the provisions of the registration rights agreement and the indenture, copies of which have been filed as exhibits to the registration statement of which this prospectus is part.

IMPORTANT FEDERAL INCOME TAX CONSIDERATIONS

      The following is a summary of the important U.S. federal income tax considerations relating to the exchange of old notes for registered notes in the exchange offer. It does not contain a complete analysis of all potential tax considerations relating to the exchange. This summary is limited to holders of old notes who hold the old notes as “capital assets” (in general, assets held for investment). Special situations, such as the following, are not addressed:

  •  tax consequences to holders who may be subject to special tax treatment, such as tax-exempt entities, dealers in securities or currencies, banks, other financial institutions, insurance companies, regulated investment companies, traders in securities that elect to use a mark-to-market method of accounting for their securities holdings or corporations that accumulate earnings to avoid U.S. federal income tax;
 
  •  tax consequences to persons holding old notes as part of a hedging, integrated, constructive sale or conversion transaction or a straddle or other risk reduction transaction;
 
  •  tax consequences to holders whose “functional currency” is not the U.S. dollar;
 
  •  tax consequences to persons who hold old notes through a partnership or similar pass-through entity;
 
  •  U.S. federal gift tax, estate tax (except as to non-United States holders) or alternative minimum tax consequences, if any; or
 
  •  any state, local or foreign tax consequences.

      The discussion below is based upon the provisions of the Internal Revenue Code of 1986, as amended, existing and proposed Treasury regulations promulgated thereunder, and rulings, judicial decisions and administrative interpretations thereunder, as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in U.S. federal income tax consequences different from those discussed below.

     Consequences of Tendering Old Notes

      The exchange of your old notes for registered notes in the exchange offer should not constitute an exchange for federal income tax purposes. Accordingly, the exchange offer should have no federal income tax consequences to you if you exchange your old notes for registered notes. For example, there should be no change in your tax basis, and your holding period should carry over to the registered notes. In addition, the federal income tax consequences of holding and disposing of your registered notes should be the same as those applicable to your old notes.

      The preceding discussion of certain U.S. federal income tax considerations of the exchange offer is for general information only and is not tax advice. Accordingly, each investor should consult its own tax advisor as to particular tax consequences to it of exchanging old notes for registered notes in the exchange offer, including the applicability and effect of any state, local or foreign tax laws, and of any proposed changes in applicable laws.

PLAN OF DISTRIBUTION

      Each broker-dealer that receives registered notes in the exchange offer for its own account must acknowledge that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of such notes. We reserve the right in our sole discretion to purchase or make offers for, or to offer registered notes for, any old notes that remain outstanding subsequent to the expiration of the exchange offer pursuant to this prospectus or otherwise and, to the extent permitted by applicable law, purchase old notes in the open market, in privately negotiated transactions or otherwise. This prospectus, as it may be amended or supplemented from time to time, may be used by all persons subject to the prospectus delivery requirements of the Securities Act, including broker-dealers in connection with resales of registered notes received in the exchange offer, where such registered notes were acquired as a result of market-making activities or other trading activities and may be used by us to purchase any old notes outstanding after expiration of the exchange offer. We have agreed that, for a period of 180 days after the expiration of the exchange offer, we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale.

      We will not receive any proceeds from any sale of registered notes by broker-dealers. Registered notes received by broker-dealers in the exchange offer for their own account may be sold from time to time in one or more transactions in the over-the counter market, in negotiated transactions, through the writing of options on the registered notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer and/or the purchasers of any such registered notes. Any broker-dealer that resells registered notes that were received by it in the exchange offer for its own account and any broker or dealer that participates in a distribution of such notes may be deemed to be an “underwriter” within the meaning of the Securities Act and any profit on any such resale of such notes and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The letter or transmittal states that, by acknowledging that it will deliver and by delivering a prospectus meeting the requirements of the Securities Act, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

      For a period of 180 days after the expiration of the exchange offer, we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents in the letter of transmittal. We and Arch Coal have agreed to pay all expenses incurred by us and Arch Coal in connection with the performance of our and Arch Coal’s obligations incident to the exchange offer, including, in the event of any shelf registration statement, the reasonable fees and disbursements of one firm or counsel acting as counsel for the holders of old notes in connection with the shelf registration statement and will indemnify holders of the notes, including any broker-dealers, against certain liabilities, including liabilities under the Securities Act.

GLOSSARY OF SELECTED MINING TERMS

      Assigned Reserves. Recoverable coal reserves that have been designated for mining by a specific operation.

      Btu — British Thermal Unit. A measure of the energy required to raise the temperature of one pound of water one degree Fahrenheit.

      Clean Air Act. Federal legislation enacted to regulate air emissions, as amended to date.

      Coal Seam. A bed or stratum of coal.

      Compliance Coal. Coal which, when burned, emits 1.2 pounds or less of sulfur dioxide per million Btus.

      Deep mine. An underground coal mine.

      Dragline. A large machine used in the surface mining process to remove the overburden, or layers of earth and rock, covering a coal seam. The dragline has a large bucket suspended from the end of a long boom. The bucket, which is suspended by cables, is able to scoop up great amounts of overburden as it is dragged across the excavation area.

      Longwall Mining. One of two major underground coal mining methods currently in use. This method employs a rotating drum, which is pulled mechanically back and forth across a face of coal that is usually several hundred feet long. The loosened coal falls onto a conveyor for removal from the mine. Longwall operations include a hydraulic roof support system that advances as mining proceeds, allowing the roof to fall in a controlled manner in areas already mined.

      Low Sulfur Coal. Coal which, when burned, emits 1.6 pounds or less of sulfur dioxide per million Btus.

      Metallurgical Coal. The various grades of coal suitable for distillation into carbon in connection with the manufacture of steel. Also known as “met” coal.

      Overburden. Layers of earth and rock covering a coal seam. In surface mining operations, overburden is removed prior to coal extraction.

      Pit. The area of the mine where the coal is actually extracted from the ground.

      Preparation Plant. A preparation plant is a facility for crushing, sizing and washing coal to prepare it for use by a particular customer. The washing process has the added benefit of removing some of the coal’s sulfur content.

      Probable Reserves. Reserves for which quantity and grade and/or quality are computed from information similar to that used for proven (measured) reserves, but the sites for inspection, sampling and measurement are farther apart or are otherwise less adequately spaced. The degree of assurance, although lower than that for proven (measured) reserves, is high enough to assume continuity between points of observation.

      Proven Reserves. Reserves for which (a) quantity is computed from dimensions revealed in outcrops, trenches, workings or drill holes; grade and/or quality are computed from the results of detailed sampling and (b) the sites for inspection, sampling and measurement are spaced so closely and the geologic character is so well defined that size, shape, depth and mineral content of reserves are well established.

      Reclamation. The restoration of land and environmental values to a mining site after the coal is extracted. Reclamation operations are usually underway where the coal has already been taken from a mine, even as mining operations are taking place elsewhere at the site. The process commonly includes “recontouring” or reshaping the land to its approximate original appearance, restoring topsoil and planting native grass and ground covers.

      Recoverable Reserves. The amount of proven and probable reserves that can actually be recovered from the reserve base taking into account all mining and preparation losses involved in producing a saleable product using existing methods and under current law.

      Scrubber. Any of several forms of chemical/ physical devices which operate to neutralize sulfur compounds formed during coal combustion. These devices combine the sulfur in gaseous emissions with other chemicals to form inert compounds, such as gypsum, which must then be removed for disposal.

      Spot Market. Sales of coal under an agreement for shipments over a period of one year or less.

      Steam Coal. Coal used in steam boilers to produce electricity.

      Sulfur. One of the elements present in varying quantities in coal that contributes to environmental degradation when coal is burned. Sulfur dioxide is produced as a gaseous by-product of coal combustion.

      Sulfur Content. Coal is commonly described by its sulfur content due to the importance of sulfur in environmental regulations. Nearly all of our coal is of low sulfur grades.

      Super-Compliance Coal. Compliance coal which, when burned, emits a particularly low amount of sulfur dioxide per million Btus is commonly referred to in the coal industry as “super-compliance” coal.

      Surface Mine. A mine in which the coal lies near the surface and can be extracted by removing overburden.

      Tons. A unit of measure equal to 2,000 pounds. Also know as a “short ton” or “net ton.”

      Unassigned Reserves. Recoverable reserves that have not yet been designated for mining by a specific operation.

      Underground Mine. Also known as a “deep” mine. Usually located several hundred feet below the earth’s surface, an underground mine’s coal is removed mechanically and transferred by shuttle car or conveyor to the surface.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(In thousands of dollars)

1. Formation of the Company

      On June 1, 1998, Arch Coal, Inc. (Arch Coal) acquired the Colorado and Utah coal operations of Atlantic Richfield Company (ARCO) and simultaneously combined the acquired ARCO operations and Arch Coal’s Wyoming operation with ARCO’s Wyoming operations in a new joint venture named Arch Western Resources, LLC (the Company). ARCO was acquired by BP p.l.c. (formerly BP Amoco) in 2000. Arch Coal has a 99% common membership interest in the Company, while BP p.l.c. has a 0.5% common membership interest and a 0.5% preferred membership interest in the Company. Net profits and losses are allocated only to the common membership interests on the basis of 99.5% to Arch Coal and 0.5% to BP p.l.c. In accordance with the membership agreement of the Company, no profit or loss is allocated to the preferred membership interest of BP p.l.c. Except for a Preferred Return, distributions to members are allocated on the basis of 99.5% to Arch Coal and 0.5% to BP p.l.c. The Preferred Return entitles BP p.l.c. to receive an annual distribution from the common membership interests equal to 4% of the preferred capital account balance at the end of the year. The Preferred Return is payable at the Company’s discretion.

      Under the terms of the agreement, BP p.l.c. has a put right which allows BP p.l.c., at any time after the seventh year of the agreement, to cause Arch Coal to purchase its members’ interest. In addition, Arch Coal has a call right which allows Arch Coal to purchase BP p.l.c.’s members’ interest as long as it pays damages as set forth in the agreement between the members. It is the members’ intention at this point to continue the joint venture.

      In connection with the formation of the Company, Arch Coal agreed to indemnify BP p.l.c. against certain tax liabilities in the event that such liabilities arise as a result of certain actions taken by Arch Coal or the Company prior to June 1, 2013. The provisions of the indemnification agreement may restrict the Company’s ability to sell or dispose of certain properties, repurchase certain of its equity interests, or reduce its indebtedness.

      The Company mines and markets steam coal from surface and deep mines for sale to utility and industrial customers in the United States and certain export markets. The Company’s principal subsidiaries are Thunder Basin Coal Company, L.L.C., which operates a surface coal mine and owns one idle mine in the Powder River Basin in Wyoming; Mountain Coal Company L.L.C., which operates one underground coal mine in Colorado; and Arch of Wyoming LLC, which operates two surface coal mines in the Hanna Basin in Wyoming. In addition to these wholly owned operating units, the Company has a 65% interest in Canyon Fuel Company. Canyon Fuel operates three underground coal mines in Utah.

2. Accounting Policies

     Principles of Consolidation

      The consolidated financial statements include the accounts of the Arch Western Resources and its subsidiaries. All subsidiaries except Canyon Fuel are wholly owned. Significant intercompany transactions and accounts have been eliminated in consolidation.

      The membership interests in Canyon Fuel are owned 65% by the Company and 35% by a subsidiary of ITOCHU Corporation, a Japanese corporation. The agreement which governs the management and operations of Canyon Fuel provides for a Management Board to manage its business and affairs. Generally, the Management Board acts by affirmative vote of the representatives of the members holding more than 50% of the membership interests. However, significant participation rights require either the unanimous approval of the members or the approval of representatives of members holding more than 70% of the

F-7

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(In thousands of dollars) — (Continued)

membership interests. Those matters which are considered significant participation rights include the following:

  •  approval of the annual business plan;
 
  •  approval of significant capital expenditures;
 
  •  approval of significant coal sales contracts;
 
  •  approval of the institution of, or the settlement of litigation;
 
  •  approval of incurrence of indebtedness;
 
  •  approval of significant mineral reserve leases;
 
  •  selection and removal of the CEO, CFO, or General Counsel;
 
  •  approval of any material change in the business of Canyon Fuel;
 
  •  approval of any disposition whether by sale, exchange, merger, consolidation, license or otherwise, and whether directly or indirectly, of all or any portion of the assets of Canyon Fuel other than in the ordinary course of business; and
 
  •  approval of request that a member provide additional services to Canyon Fuel.

      The Canyon Fuel agreement also contains various restrictions on the transfer of membership interests in Canyon Fuel. As a result of these super-majority voting rights, the Company’s 65% ownership of Canyon Fuel is accounted for on the equity method in the consolidated financial statements. Income from Canyon Fuel is reflected in the Consolidated Statements of Operations as income from equity investments. (See additional discussion in “Investment in Canyon Fuel” in Note 4.)

     Accounting Estimates

      The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

     Cash and Cash Equivalents

      Cash and cash equivalents are stated at cost. Cash equivalents consist of highly liquid investments with an original maturity of three months or less when purchased.

     Inventories

      Inventories consist of the following:

                 
December 31,

2002 2001


Coal
  $ 15,475     $ 12,466  
Supplies, net of allowance
    20,252       19,002  
     
     
 
    $ 35,727     $ 31,468

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(In thousands of dollars) — (Continued)

      Coal and supplies inventories are valued at the lower of average cost or market. Coal inventory costs include labor, supplies, equipment costs and operating overhead. The Company has recorded a valuation allowance for slow-moving and obsolete supplies inventories of $8.3 million and $8.1 million at December 31, 2002 and 2001, respectively.

     Coal Acquisition Costs and Prepaid Royalties

      Coal lease rights obtained through acquisitions are capitalized and amortized primarily by the units-of-production method over the estimated recoverable reserves. Amortization occurs either as the Company mines on the property or as others mine on the property through subleasing transactions.

      Rights to leased coal lands are often acquired through royalty payments. Where royalty payments represent prepayments recoupable against production, they are capitalized, and amounts expected to be recouped within one year are classified as a current asset. As mining occurs on these leases, the prepayment is charged to cost of coal sales.

     Coal Supply Agreements

      Acquisition costs allocated to coal supply agreements (sales contracts) are capitalized and amortized on the basis of coal to be shipped over the term of the contract. Value is allocated to coal supply agreements based on discounted cash flows attributable to the difference between the above-market contract price and the then-prevailing market price. Accumulated amortization for sales contracts was $28.9 million and $28.0 million at December 31, 2002 and 2001, respectively.

     Exploration Costs

      Costs related to locating coal deposits and determining the economic mineability of such deposits are expensed as incurred.

     Property, Plant and Equipment

      Property, plant and equipment are recorded at cost. Interest costs applicable to major asset additions are capitalized during the construction period. The Company capitalized $711,000 of interest in the year ended December 31, 2002 and did not capitalize interest in the years ended December 31, 2001 and 2000.

      Expenditures which extend the useful lives of existing plant and equipment or increase the productivity of the asset are capitalized. Costs of purchasing rights to coal reserves and developing new mines, or significantly expanding the capacity of existing mines, are capitalized and amortized using the units-of-production method over the estimated recoverable reserves that are associated with the property being benefited. At December 31, 2002, all mineral reserves of the Company that are capitalized are being amortized on the units-of-production method through Company operations. Except for preparation plants and loadouts, plant and equipment are depreciated principally on the straight-line method over the estimated useful lives of the assets, which range from three to 28 years. Preparation plants and loadouts are depreciated using the units-of-production method over the estimated recoverable reserves, subject to a minimum level of depreciation.

     Asset Impairment

      If facts and circumstances suggest that a long-lived asset may be impaired, the carrying value is reviewed. If this review indicates that the value of the asset will not be recoverable, as determined based on projected undiscounted cash flows related to the asset over its remaining life, then the carrying value of the asset is reduced to its estimated fair value.

     Revenue Recognition

      Coal sales revenues include sales to customers of coal produced at Company operations and coal purchased from other companies. The Company recognizes revenue from coal sales at the time title passes to the customer. Transportation costs that are billed by the Company and reimbursed to the transportation provider are included in coal sales and cost of coal sales. Revenues from sources other than coal sales, including gains and losses from dispositions of long-term assets, are included in other revenues and are recognized as services are performed or otherwise earned.

     Derivative Financial Instruments

      The Company utilizes derivative financial instruments in the management of its interest rate and diesel fuel exposures. The Company does not use derivative financial instruments for trading or speculative purposes. The Company adopted Statement of Financial Accounting Standards No. 133, Accounting for Derivative Instruments and Hedging Activities (“FAS 133”), on January 1, 2001. FAS 133 requires all derivative financial instruments to be reported on the balance sheet at fair value. Changes in fair value are recognized either in earnings or equity, depending on the nature of the underlying exposure being hedged and how effective the derivatives are at offsetting price movements in the underlying exposure. All of the Company’s existing derivative positions, which consist of interest rate swaps and heating oil swaps, qualified for cash flow hedge accounting under FAS 133 and are deemed to be effective for the variable-rate debt and diesel fuel purchases being hedged. Prior to the adoption of FAS 133, the fair values of the swap agreements were not recognized in the financial statements. Gains and losses on terminations of swap agreements that qualify as cash flow hedges are deferred on the balance sheets (in other long-term liabilities) and amortized as an adjustment to expense over the remaining original term of the terminated swap agreement.

      The Company evaluates all derivative instruments each quarter to determine that they are highly effective. Any ineffectiveness is recorded in the Consolidated Statements of Operations. Ineffectiveness for the year ended December 31, 2002 was $0.4 million and was recorded as a reduction of other expenses in the Consolidated Statements of Operations.

      The Company enters into interest-rate swap agreements to modify the interest characteristics of outstanding Company debt. The swap agreements essentially convert variable-rate debt to fixed-rate debt. These agreements require the exchange of amounts based on variable interest rates for amounts based on fixed interest rates over the life of the agreement. The Company accrues amounts to be paid or received under interest-rate swap agreements over the lives of the agreements. Such amounts are recognized as adjustments to interest expense over the lives of agreements, thereby adjusting the effective interest rate on the Company’s debt.

      The Company enters into heating oil swaps to eliminate volatility in the price to purchase diesel fuel for its operations. The swap agreements essentially fix the price paid for diesel fuel by requiring the Company to pay a fixed heating oil price and receive a floating heating oil price. The changes in the floating heating oil price highly correlate to changes in diesel fuel costs. The heating oil swaps hedge anticipated diesel fuel purchases over the next year.

      The Company recorded the fair value of the derivative financial instruments on the balance sheet as an “other non-current liability” and recorded the unrealized loss, net of tax, in “accumulated other comprehensive loss.” The adoption of FAS 133 had no impact on the Company’s results of operations or cash flows.

     Accounting Development

      Effective January 1, 2003, the Company adopted Statement of Financial Accounting Standards No. 143, Accounting for Asset Retirement Obligations (“FAS 143”). The Statement requires legal obligations associated with the retirement of long-lived assets to be recognized at fair value at the time the obligations are incurred. Upon initial recognition of a liability, that cost should be capitalized as part of the related long-lived asset and allocated to expense over the useful life of the asset.

      In November 2002, the Financial Accounting Standards Board issued FASB Interpretation No. 45, Guarantors’ Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others. The disclosure requirements of this standard were effective for the year ended December 31, 2002. The other provisions are effective prospectively for guarantees issued or modified after January 1, 2003. The Company does not expect the adoption of this interpretation to have a material impact on its financial statements.

      In January 2003, the Financial Accounting Standards Board issued FASB Interpretation No. 46, Consolidation of Variable Interest Entities. The interpretation clarifies the application of Accounting Research Bulletin No. 51, Consolidated Financial Statements, to certain types of entities. The Company does not expect the adoption of this interpretation to have a material impact on its financial statements. The interpretation applies for the first interim period beginning after June 15, 2003.

     Reclassifications

      Certain amounts in the financial states have been reclassified to conform with changes to the presentation of selling, general and administrative expenses, with no resulting effect on previously reported net income or members’ equity.

3. Nonrecurring Revenues and Expenses

      During the year ended December 31, 2002, the Company was notified by the Bureau of Land Management (BLM) that it would receive a royalty rate reduction for certain tons mined at its West Elk location. The rate reduction applies to a specified number of tons beginning October 1, 2001 and ending no later than October 1, 2005. The retroactive portion of the refund totaled $3.3 million and has been recognized in 2002 as a reduction of cost of coal sales. Additionally, Canyon Fuel was notified by the BLM that it would receive a royalty rate reduction for certain tons mined at its Skyline mine. The rate reduction applies to certain tons mined from September 1, 2001 through September 1, 2006. The Company’s share of the retroactive refund was $1.1 million and is reflected in 2002 as income from equity investments in the consolidated statement of operations.

      The Company’s operating results for the years ended December 31, 2001 and 2000 reflect insurance settlements of $9.4 million and $31.0 million, respectively, as part of the Company’s coverage under its property and business interruption policy. The insurance payments represent settlement for losses incurred at the West Elk mine in Gunnison County, Colorado, which was idled from January 28, 2000 to July 12, 2000, following the detection of combustion-related gases.

      During 2001, Canyon Fuel recognized recoveries of previously paid property taxes. The Company’s share of these recoveries was $2.6 million and is reflected in income from equity investment on the consolidated statement of operations for the year ended December 31, 2001. During 2001, the Company also recorded a $5.1 million gain as a result of selling land.

The Company’s investment in Canyon Fuel reflects purchase adjustments primarily related to the reduction in amounts assigned to sales contracts, mineral reserves and other property, plant and equipment. The purchase adjustments are amortized consistent with the underlying assets of the joint venture. During 2001, in accordance with FAS 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of, Canyon Fuel wrote off its investment in LAXT, a coal terminal located in Los Angeles, resulting in a charge of $10.1 million. The Company did not value LAXT in its Canyon Fuel purchase allocation and, therefore, there was no impact of the charge on the Company’s financial position.

5. Other Comprehensive Income

      Other comprehensive income items under FAS 130, Reporting Comprehensive Income, are transactions recorded in members’ equity during the year, excluding net income and transactions with members.

7. Debt and Financing Arrangements

      On April 18, 2002, the Company completed a refinancing of its existing $675.0 million term loan. The new credit facility consisted of five- and six-year non-amortizing term loans totaling $675.0 million. The five-year non-amortizing term loan was for $150.0 million, and the six-year non-amortizing term loan was for $525.0 million. These were secured by the Company’s membership interests in its subsidiaries and the

Company’s receivable balance from Arch Coal. The rate of interest under both loans was a rate based on LIBOR (weighted average rate at December 31, 2002 of 4.5%; weighted average rate of 3.25% for $675 million term loan at December 31, 2001). The Company repaid and retired the outstanding indebtedness under both loans in June 2003.

      The Company’s term loans contain financial and other covenants that limit the ability of the Company to, among other things, effect acquisitions or dispositions and borrow additional funds and that require the Company to, among other things, maintain various financial ratios and comply with various other financial covenants. Failure by the Company to comply with such covenants could result in an event of default which, if not cured or waived, could have a material adverse effect on the Company. The Company was in compliance with these covenants at December 31, 2002.

      The Company enters into interest rate swap agreements to modify the interest characteristics of outstanding debt. At December 31, 2002, the Company had interest rate swap agreements having a total notional value of $500 million including $250 million for which the fixed rate becomes effective as of October 2003. These swap agreements are used to convert variable rate debt to fixed rate debt. Under these swap agreements, the Company pays a weighted average fixed rate of 4.79% (before the credit spread over LIBOR) and is receiving a weighted average variable rate based upon 30-day and 90-day LIBOR. At December 31, 2002, the remaining terms of the swap agreements ranged from 32 to 57 months.

8. Fair Values of Financial Instruments

      The following methods and assumptions were used by the Company in estimating its fair value disclosures for financial instruments:

        Cash and cash equivalents: The carrying amounts approximate fair value.
 
        Debt: The carrying amounts of the Company’s borrowings under its revolving credit agreement, lines of credit, variable-rate term loans and other long-term debt approximate their fair value.
 
        Interest rate swaps: The fair values of interest rate swaps are based on quoted prices, which reflect the present value of the difference between estimated future amounts to be paid and received. At December 31, 2002 and 2001 the fair value of these swaps are liabilities of $34.1 million and $22.5 million, respectively.
 
        Heating oil swaps: The fair values of heating oil swaps are based on quoted prices. The fair value of these swaps are an asset of $0.3 million at December 31, 2002 and a liability of $.7 million at December 31, 2001.

9. Accrued Workers’ Compensation

      The Company is liable under the federal Mine Safety and Health Act of 1977, as amended, to provide for pneumoconiosis (black lung) benefits to eligible employees, former employees, and dependents with respect to claims filed by such persons on or after July 1, 1973. The Company is also liable under various states’ statutes for black lung benefits. The Company currently provides for federal and state claims principally through a self-insurance program. Charges are being made to operations as determined by independent actuaries, at the present value of the actuarially computed present and future liabilities for such benefits over the employees’ applicable years of service. In addition, the Company is liable for

      Actuarial gains and losses are amortized over five years.

10. Employee Benefit Plans

 
Defined Benefit Pension and Other Postretirement Benefit Plans

      The Company has non-contributory defined benefit pension plans covering certain of its salaried and non-union hourly employees. Benefits are generally based on the employee’s years of service and compensation. The Company funds the plans in an amount not less than the minimum statutory funding requirements nor more than the maximum amount that can be deducted for federal income tax purposes.

      The Company also currently provides certain postretirement medical/life insurance coverage for eligible employees. Generally, covered employees who terminate employment after meeting eligibility requirements are eligible for postretirement coverage for themselves and their dependents. The salaried employee postretirement medical/life plans are contributory, with retiree contributions adjusted periodically, and contain other cost-sharing features such as deductibles and coinsurance. The postretirement medical plan for retirees who were members of the United Mine Workers of America (“UMWA”) is not contributory. The Company’s current funding policy is to fund the cost of all postretirement medical/ life

      In determining the other postretirement benefit obligation at December 31, 2002, a 7.50% annual rate of increase in the cost of health care benefits is assumed for 2003. This rate gradually decreases to 5.00% in 2008 and remains at that level thereafter. The health care cost trend rate assumption can have a significant effect on the amounts reported. However, as the employer contribution cap was reached in 2002, the impact of health care cost trend rate changes is not material.

      The following table details the components of pension and other postretirement benefit costs.

The Company does not fund its other postretirement liabilities.

      In 2000, the Company amended its postretirement medical/life insurance plan to change eligibility requirements to 10 years of service after reaching age 45 for salaried and non-union hourly participants. This change triggered a curtailment that resulted in the recognition of $2.6 million in previously unrecognized prior service gains.

     Other Plans

      The Company sponsors savings plans which were established to assist eligible employees in providing for their future retirement needs. The Company’s contributions to the plans were $2.8 million in 2002 and 2001, and $2.7 million in 2000.

11. Accrued Reclamation and Mine Closing Costs

      The federal Surface Mining Control and Reclamation Act of 1977 and similar state statutes require that mine property be restored in accordance with specified standards and an approved reclamation plan. The Company accrues for the costs of final mine closure reclamation over the estimated useful mining life of the property. These costs relate to reclaiming the pit and support acreage at surface mines and sealing portals at deep mines. Other costs of final mine closure common to both types of mining are related to reclaiming refuse and slurry ponds. The Company also accrues for significant reclamation that is completed during the mining process prior to final mine closure. The establishment of the final mine closure reclamation liability and the other ongoing reclamation liability is based upon permit requirements and requires various estimates and assumptions, principally associated with costs and productivities. The Company accrued $7.4 million, $6.3 million and $5.7 million in 2002, 2001 and 2000, respectively, for current and final mine closure reclamation. Cash payments for final mine closure reclamation and current disturbances approximated $1.3 million, $3.1 million and $3.2 million for 2002, 2001 and 2000, respectively. Periodically, the Company reviews its entire environmental liability and makes necessary adjustments for permit changes as granted by state authorities, additional costs resulting from accelerated mine closures, and revisions to costs and productivities, to reflect current experience. These recosting adjustments are recorded in cost of coal sales. No adjustments were deemed necessary during 2002, 2001

and 2000. The Company’s management believes it is making adequate provisions for all expected reclamation and other costs associated with mine closures.

      As discussed in Note 1, beginning January 1, 2003, the Company will begin accounting for its final mine closure reclamation liabilities in accordance with FAS 143.

12. Concentration of Credit Risk and Major Customers

      The Company places its cash equivalents in investment-grade short-term investments and limits the amount of credit exposure to any one commercial issuer.

      The Company markets its coal principally to electric utilities in the United States. As of December 31, 2002 and 2001, accounts receivable from electric utilities located in the United States totaled $53.4 million and $57.1 million, respectively. Generally, credit is extended based on an evaluation of the customer’s financial condition, and collateral is not generally required. Credit losses are provided for in the financial statements and historically have been minimal.

      The Company is committed under long-term contracts to supply coal that meets certain quality requirements at specified prices. These prices are generally adjusted based on indices. Quantities sold under some of these contracts may vary from year to year within certain limits at the option of the customer. Sales (including spot sales) to major customers were as follows:

                         
2002 2001 2000



Southern Company
  $ 53,693     $ 34,871     $ 16,691  
Tennessee Valley Authority
  $ 49,178     $ 38,940     $ 29,758  

13. Related Party Transactions

      The Company leases certain assets at its Thunder Basin operation from Little Thunder Leasing Company, a subsidiary of BP p.l.c. Lease expense for Little Thunder Leasing Company for the years ended December 31, 2002, 2001 and 2000 totaled $3.4 million, $7.6 and $7.5 million, respectively.

      During 2000, the Company began mining on portions of a federal lease known as the Thundercloud tract. The Thundercloud tract contains approximately 353 million tons of demonstrated coal reserves and is contiguous to Company operations. Rights to the tract are owned by Arch Coal. Prior to mining, the Company entered into a sublease transaction with Arch Coal, which requires annual advance royalty payments which are fully recoupable against production on the Thundercloud tract. During 2002, 2001, and 2000, the Company made $12.7 million, $4.75 million, and $2.0 million, respectively, of advance royalty payments associated with this lease. The remaining payments are reflected in Note 14 under the caption “Royalties.” In addition, the Company also pays a production royalty of 5.5% of realization and a $0.01 per ton override royalty for every ton mined from the Thundercloud tract, resulting in production royalties paid to Arch Coal of $7.3 million, $4.9 million, and $2.4 million during 2002, 2001 and 2000, respectively.

      The Company’s cash transactions are managed by Arch Coal. Cash paid to or from the Company that is not considered a distribution or a contribution is maintained in an Arch Coal receivable account. At December 31, 2002 and 2001, the receivable from Arch Coal was $333.8 million and $259.8 million, respectively. This amount earns interest from Arch Coal at the prime interest rate. Interest earned for the years ended December 31, 2002, 2001 and 2000 was $13.6 million, $15.5 million and $13.7 million, respectively. The receivable is payable on demand by the Company; however, it is currently management’s intention to not demand payment of the receivable within the next year. Therefore, the receivable is classified on the consolidated balance sheets as long-term.

      The Company has historically paid selling, general and administrative services fees to Arch Coal. These fees were not intended to represent the fair value of the services performed, nor did they approximate amounts that would be expected to be incurred if the Company were a stand-alone entity. In connection with the Company’s registration of debt securities with the Securities and Exchange Commission, management of Arch Coal allocated additional expenses to the Company in the amount of $10.7 million, $10.8 million and $9.0 million for the years ended December 31, 2002, 2001 and 2000, respectively. Expenses were allocated based on Arch Coal’s best estimates of proportional or incremental costs, whichever is more representative of costs incurred by Arch Coal on behalf of the Company. Allocated expenses are not necessarily representative of costs that would be incurred if the company operated on a stand-alone basis. The following additional costs have been included in selling, general and administrative expenses in the accompanying condensed consolidated statements of operations. Arch Coal contributed these additional expenses to the Company. These additional expenses are not subject to repayment by the Company and are reflected as a capital contribution to the Company from Arch Coal.

      As described in Note 1, the Company has a 65% ownership interest in Canyon Fuel which is accounted for on the equity method. The Company receives administration and production fees from Canyon Fuel for managing the Canyon Fuel operations. The fee arrangement is calculated annually and is approved by the Canyon Fuel Management Board. The production fee is calculated on a per-ton basis while the administration fee represents the costs incurred by the Company’s employees related to Canyon Fuel administrative matters. The fees recognized as other income by the Company and as expense by Canyon Fuel were $9.5 million, $8.1 million and $7.4 million for the years ended December 31, 2002, 2001 and 2000, respectively. Amounts receivable from Canyon Fuel were $6.3 million and $2.7 million as of December 31, 2002 and 2001, respectively. Such amounts are classified as other receivables in the Consolidated Balance Sheets.

14. Commitments and Contingencies

      The Company leases equipment, land and various other properties under noncancelable long-term leases, expiring at various dates. Rental expense related to these operating leases amounted to $5.1 million in 2002, $9.1 million in 2001 and $9.6 million in 2000. The Company has also entered into various non-cancelable royalty lease agreements and federal lease bonus payments under which future minimum payments are due.

      The Company is a party to numerous claims and lawsuits with respect to various matters. The Company provides for costs related to contingencies when a loss is probable and the amount is reasonably determinable. After conferring with counsel, it is the opinion of management that the ultimate resolution of pending claims given existing legal accruals, will not have a material adverse effect on the consolidated financial condition, results of operations or liquidity of the Company.

15. Cash Flow

      The changes in operating assets and liabilities as shown in the consolidated statements of cash flows are comprised of the following:

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(In thousands of dollars)
MARCH 31, 2003
(UNAUDITED)

Note A — General

      The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles for interim financial reporting and Securities and Exchange Commission regulations, but are subject to any year-end adjustments that may be necessary. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Results of operations for the period ended March 31, 2003 are not necessarily indicative of results to be expected for the year ending December 31, 2003.

      Arch Western Resources, LLC (the “Company”) was formed as a joint venture on June 1, 1998 when Arch Coal, Inc. (“Arch Coal”) acquired the United States coal operations of Atlantic Richfield Company and combined these operations with Arch Coal’s western operations. Arch Western’s membership interests are owned 99% by Arch Coal and 1% by an affiliate of BP p.l.c. (“BP”), the successor to Atlantic Richfield Company. Arch Coal’s ownership is comprised entirely of common membership interests, while BP’s ownership is comprised of a 0.5% common membership interest and a 0.5% preferred membership interest.

      Under the terms of the Company’s membership agreement, net profits and losses are allocated only to the common membership interests on the basis of 99.5% to Arch Coal and 0.5% to BP. No profit or loss is allocated to the preferred membership interest of BP. Except for a Preferred Return, distributions to members are allocated on the basis of 99.5% to Arch Coal and 0.5% to BP. The Preferred Return entitles BP to receive an annual distribution from the common membership interests equal to 4% of the preferred capital account balance at the end of the year. The Preferred Return is payable at the Company’s discretion.

      The Company mines and markets steam coal from surface and deep mines for sale to utility and industrial customers in the United States and certain export markets. The Company’s principal subsidiaries are Thunder Basin Coal Company, L.L.C., which operates a surface coal mine and owns one idle mine in the Powder River Basin in Wyoming; Mountain Coal Company, L.L.C., which operates one underground coal mine in Colorado; and Arch of Wyoming, which operates two surface coal mines in the Hanna Basin in Wyoming. In addition to these wholly owned operating units, the Company has a 65% interest in Canyon Fuel Company, LLC (“Canyon Fuel”). Canyon Fuel operates three underground coal mines in Utah. This interest is accounted for on the equity method in the financial statements as a result of certain super-majority voting rights in the Canyon Fuel joint venture agreement. Income from Canyon Fuel is reflected in the consolidated statements of operations as income from equity investment.

Note B — Adoption of FAS 143

      On January 1, 2003, the Company adopted Statement of Financial Accounting Standards No. 143, Accounting for Asset Retirement Obligations (FAS 143). FAS 143 requires legal obligations associated with the retirement of long-lived assets to be recognized at fair value at the time the obligations are incurred. Upon initial recognition of a liability, that cost should be capitalized as part of the related long-lived asset and allocated to expense over the useful life of the asset. Previously, the Company accrued for the expected costs of these obligations over the estimated useful mining life of the property.

      The cumulative effect of the change on prior years resulted in a charge to income of $18.3 million, which is included in income for the quarter ended March 31, 2003. In addition, the net income of the Company, excluding the cumulative effect of accounting change, for the quarter ended March 31, 2003 is $1.2 million less than it would have been if the Company had continued to account for these obligations

under its old method. The unaudited proforma amounts below reflect the retroactive application of FAS 143 and the corresponding elimination of the cumulative accounting change:

Net (loss)
  $ (10,167 )   $ (1,836 )
Proforma net income
    8,111       (3,111 )

      If the Company had accounted for its asset retirement obligations in accordance with FAS 143 for all periods presented, the asset retirement obligation liability (including amounts classified as current) would have been $104.2 million, $106.6 million, and $113.7 million at January 1, 2002, March 31, 2002, and December 31, 2002, respectively.

Arch Western’s income from its equity investment in Canyon Fuel
  $ 8,151     $ 1,268  
     
     
 

      The Company’s income from its equity investment in Canyon Fuel represents 65% of Canyon Fuel’s net income after adjusting for the effect of purchase adjustments primarily related to its investment in Canyon Fuel. The Company’s investment in Canyon Fuel reflects purchase adjustments primarily related to the reduction in amounts assigned to sales contracts, mineral reserves and other property, plant and equipment. The purchase adjustments are amortized consistent with the underlying assets of the joint venture.

      Effective January 1, 2003, Canyon Fuel adopted FAS 143 and recorded a cumulative expense loss of $2.4 million. The Company’s 65% share of this amount was offset by purchase adjustments of $0.5 million. These amounts are included in the cumulative effect of accounting change reported in the Company’s condensed consolidated statements of operations.

Note F — Debt

      The Company’s credit facility consisted of five- and six-year non-amortizing term loans totaling $675.0 million. The five-year non-amortizing term loan was for $150.0 million, and the six-year non-amortizing term loan was for $525.0 million. These were secured by the Company’s membership interests in its subsidiaries and the Company’s receivable balance from Arch Coal. The rate of interest under both loans was a variable rate based on LIBOR. The Company repaid and retired the outstanding indebtedness under both loans in June 2003.

Note G — Contingencies

      The Company is a party to numerous claims and lawsuits with respect to various matters. The Company provides for costs related to contingencies when a loss is probable and the amount is reasonably determinable. After conferring with counsel, it is the opinion of management that the ultimate resolution of these claims, to the extent not previously provided for, will not have a material adverse effect on the consolidated financial position, results of operations or liquidity of the Company.

Note H — Related Party Transactions

      The Company has historically paid selling, general and administrative services fees to Arch Coal. These fees were not intended to represent the fair value of the services performed, nor did they approximate amounts that would be expected to be incurred if the Company were a stand-alone entity. In connection with the Company’s registration of debt securities with the Securities and Exchange Commission, management of Arch Coal allocated additional expenses to the Company in the amount of $3.3 million in the first quarter of 2003 and $2.7 million in the first quarter of 2002. Expenses were allocated based on Arch Coal’s best estimates of proportional or incremental costs, whichever is more representative of costs incurred by Arch Coal on behalf of the Company. The following additional costs have been included in selling, general and administrative expenses in the accompanying condensed consolidated statements of operations.

Note I — Reclassifications

      Certain amounts in the 2002 financial statements have been reclassified to conform with the classifications in the 2003 financial statements with no effect on previously reported net income (loss) or members’ equity.

Note J — Supplemental Condensed Consolidating Financial Information

PART II

 

INFORMATION NOT REQUIRED IN PROSPECTUS

 
Item 20. Indemnification of Directors and Officers

      The Issuer and each subsidiary guarantor are limited liability companies organized under the laws of the State of Delaware. Section 18-108 of the Delaware Limited Liability Company Act, or the Delaware LLC Act, provides that a limited liability company may, and shall have the power to, indemnify and hold harmless any member or manager or other person from and against any and all claims and demands whatsoever, subject to such standards and restrictions, if any, as are set forth in its limited liability company agreement.

      The Limited Liability Company Agreements of Arch of Wyoming, LLC and Arch Western Finance, LLC each provide that no member, director or officer of either company will be liable to the company, or any other person or entity who has an interest in the company, for any loss, damage or claim incurred by reason of any act or omission performed or omitted by such member, director or officer in good faith on behalf of the company and in a manner reasonably believed to be within the scope of the authority conferred on such member, director or officer by the company’s limited liability company agreement, unless such act or omission constituted bad faith, gross negligence, fraud or willful misconduct. To the fullest extent permitted by applicable law, indemnified parties will be entitled to indemnification from the company for any loss, damage or claim incurred by an indemnified party by reason of any act or omission performed or omitted by an indemnified party in good faith on behalf of the company and in a manner reasonably believed to be within the scope of the authority conferred on the indemnified party by the company’s limited liability company agreement, unless such act or omission constituted bad faith, gross negligence, fraud or willful misconduct; provided, however, that any indemnity will be provided out of and to the extent of the company’s assets only, and no member will have personal liability on account of any indemnification obligation.

      The Limited Liability Company Agreement of Arch Western Resources, LLC provides that no member or officer will be liable in damages for any act or failure to act in such person’s capacity as a member or officer on behalf of Arch Western Resources unless such act or omission constituted bad faith, gross negligence, fraud or willful misconduct of such person or a violation by such person of the Limited Liability Company Agreement of Arch Western Resources. Subject to the Limited Liability Company Agreement of Arch Western Resources, each member and officer will be indemnified and held harmless by Arch Western Resources, its receiver or trustee from and against any liability for damages and expenses, including reasonable attorneys’ fees and disbursements and amounts paid in settlement, resulting from any threatened, pending or completed action, suit or proceeding relating to or arising out of such person’s acts or omissions in such person’s capacity as a member or an officer on behalf of Arch Western Resources, except to the extent that such damages or expenses result from the bad faith, gross negligence, fraud or willful misconduct of such person or a violation by such person of the Limited Liability Company Agreement of Arch Western Resources. Any indemnity by Arch Western Resources, its receiver or trustee will be provided out of and to the extent of the property of Arch Western Resources only.

      The Bylaws of Mountain Coal Company, L.L.C. and Thunder Basin Coal Company, L.L.C. both provide that no director or officer of the company will have any liability to the company or its members for any losses sustained or liabilities incurred as a result of any act or omission of such director or officer if (i) the director or officer acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the interests of the company and (ii) the conduct of the director or officer did not constitute actual fraud, gross negligence, or willful misconduct. The company will indemnify and hold harmless its directors and officers from and against any and all losses, claims, demands, costs, damages, liabilities, expenses of any nature (including reasonable attorneys’ fees and disbursements), judgments, fines, settlements, and other amounts arising from any and all claims, demands, actions, suits, or proceedings, civil, criminal, administrative, or investigative, in which an indemnitee may be involved, or threatened to be involved, as a party or otherwise, arising out of or incidental to the business of the

II-1


Table of Contents

company, regardless of whether an indemnitee continues to be a director or officer at the time any such liability or expense is paid or incurred, if (i) the indemnitee acted in good faith and in a manner it or he or she reasonably believed to be in, or not opposed to, the interests of the company, and, with respect to any criminal proceeding, had no reason to believe his or her conduct was unlawful and (ii) the indemnitee’s conduct did not constitute actual fraud, gross negligence or willful misconduct.

Item 22. Undertakings.

(a)  The undersigned registrant hereby undertakes that for purposes of determining any liability under the Securities Act of 1933, as amended (the “Securities Act”), each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), (and where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

The undersigned registrants hereby undertake:

  (1)  To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

  (i)  To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

  (ii)  To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent nor more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

  (iii)  To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

  (2)  That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
  (3)  To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

  Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange

II-3


Table of Contents

  Commission such indemnification is against public policy as expressed in the Securities Act, and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act, and will be governed by the final adjudication of such issue.

(b)  The undersigned registrants hereby undertake to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.
 
(c)  The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

LLC, a limited liability company organized under the laws of Delaware ("Arch
Western"), and each of Arch Western's wholly owned subsidiaries listed in
Schedule II hereto (each a "Subsidiary Guarantor" and collectively the

as the "Guarantors"). The Securities are to be issued under an indenture (the
"Indenture"), dated as of June 25, 2003 among the Issuer, the Guarantors and the

constitute a valid and binding obligation of Arch Western and each Subsidiary
Guarantor, enforceable against each of them in accordance with its terms, and
will be entitled to the benefits of the Indenture (subject, as to the
enforcement of remedies, to applicable bankruptcy, reorganization, insolvency,
moratorium or other laws affecting creditors' rights generally from time to time
in effect and to general principles of equity).

                  (z)      The Registration Rights Agreement has been duly
authorized and, when executed and delivered by each of the Issuer, the Company
and the Guarantors, will constitute a valid and binding obligation of the

affecting creditors' rights generally from time to time in effect and to general
principles of equity and except as rights to indemnification or contribution
thereunder may be limited by federal or state securities laws or the public

observance of any obligation, agreement, covenant or condition contained in any
contract, indenture, mortgage, deed of trust, loan or credit agreement, note,
lease or other agreement or instrument to which the Company or any of its
subsidiaries is a party or by which it or any of them may be bound, or to which

or defaults or liens, charges or

                                        7

action result in any violation of the provisions of the charter or by-laws of
the Company or any of its subsidiaries or any applicable law, statute, rule,
regulation, judgment, order, writ or decree of any government, government
instrumentality or court, domestic or foreign, having jurisdiction over the
Company or any of its subsidiaries or any of their assets, properties or

manufacturers, customers or contractors, which, in either case, may reasonably
be expected to result in a Material Adverse Effect.

                  (dd)     There is no action, suit, proceeding, inquiry or

Governmental Licenses to be in full force and effect would not result in a
Material Adverse Effect. Neither the Company nor any of its subsidiaries has
received any notice of proceedings relating to the revocation or modification of
any such Governmental Licenses which, singly or in the aggregate, if the subject
of an unfavorable decision, ruling or finding, would result in a Material
Adverse Effect.

                  (a)      It has not offered or sold, and will not offer or
sell, any Securities except (i) to those it reasonably believes to be qualified
institutional buyers (as defined in Rule 144A under the Act) and that, in
connection with each such sale, it has taken or will take reasonable steps to
ensure that the purchaser of such Securities is aware that such sale is being
made in reliance on Rule 144A or (ii) in accordance with the restrictions set
forth in Exhibit A hereto.

Guarantors, jointly and severally, agrees with each Initial Purchaser that:

furnish to each Initial Purchaser and to counsel for the Initial Purchasers,

copies of the Final Memorandum and any amendments and supplements thereto as
they may reasonably request.

                  (b)      The Issuer, the Company and the Guarantors will not
amend or supplement the Final Memorandum without the prior written consent of
the Representatives.

                  (c)      If at any time prior to the completion of the sale of
the Securities by the Initial Purchasers (as determined by the Representatives),
any event occurs as a result of which the Final Memorandum, as then amended or
supplemented, would include any untrue statement of a material fact or omit to
state any material fact necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading, or if it should
be necessary to amend or supplement the Final Memorandum to comply with
applicable law, the Company promptly (i) will notify the Representatives of any
such event; (ii) subject to the requirements of paragraph (b) of this Section 5,
will prepare an amendment or supplement that will correct such statement or
omission or effect such compliance; and (iii) will supply any supplemented or
amended Final Memorandum to the several Initial Purchasers and counsel for the
Initial Purchaser without charge in such quantities as they may reasonably
request.

                  (d)      The Issuer, the Company and the Guarantors will
arrange, if necessary, for the qualification of the Securities for sale by the
Initial Purchasers under the laws of such jurisdictions as the Initial
Purchasers may designate and will maintain such qualifications in effect so long
as required for the sale of the Securities; provided that in no event shall the
Issuer, the Company and the Guarantors be obligated to qualify to do business in
any jurisdiction where it is not now so qualified or to take any action that
would subject it to service of process in suits, other than those arising out of
the offering or sale of the Securities, in any jurisdiction where it is not now
so subject. The Company will promptly advise the Representatives of the receipt
by the Issuer, the Company or any Guarantor of any notification with respect to
the suspension of the qualification of the Securities for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purpose.

                  (e)      The Issuer, the Company and the Guarantors will not,
and will not permit any of their respective Affiliates to, resell any Securities
that have been acquired by any of them.

                  (f)      Neither the Issuer, nor the Company, nor any
Guarantor, nor any of their respective Affiliates, nor any person acting on
their behalf will, directly or indirectly, make offers or sales of any security,
or solicit offers to buy any security, under circumstances that would require
the registration of the Securities under the Act.

                                       13



                  (g)      Neither the Issuer, nor the Company, nor any
Guarantor, nor any of their respective Affiliates, nor any person acting on its
or their behalf will engage in any form of general solicitation or general
advertising (within the meaning of Regulation D) in connection with any offer or
sale of the Securities in the United States.

                  (h)      So long as any of the Securities are "restricted
securities" within the meaning of Rule 144(a)(3) under the Act, each of the
Company and Arch Western will, unless it becomes subject to and complies with
Section 13 or 15(d) of the Exchange Act, provide to each holder of such
restricted securities and to each prospective purchaser (as designated by such
holder) of such restricted securities, upon the request of such holder or
prospective purchaser, any information required to be provided by Rule
144A(d)(4) under the Act. This covenant is intended to be for the benefit of the
holders, and the prospective purchasers designated by such holders, from time to
time of such restricted securities.

                  (i)      Neither the Issuer, nor the Company, nor any
Guarantor, nor any of their respective Affiliates, nor any person acting on
their behalf will engage in any directed selling efforts with respect to the
Securities, and each of them will comply with the offering restrictions

         by-laws of the Company or any of its subsidiaries, or any applicable
         law, statute, rule, regulation, judgment, order, writ or decree, known
         to me, of any government, government instrumentality or court, domestic
         or foreign, having jurisdiction over the Company or any of its
         subsidiaries or any of their respective properties, assets or
         operations.

         operations thereof or the consummation of the transactions contemplated
         under this Agreement, the Indenture, the Registration Rights Agreement,

         the Company for the year ended December 31, 2002 under "Business--Legal
         Proceedings" and incorporated by reference in the Final Memorandum, to

         party are accurate in all material respects.

                  Robert G. Jones shall also state that nothing has come to his
attention that causes him to believe that the Final Memorandum, (except for
financial statements and schedules and other financial data included or
incorporated by reference therein or omitted therefrom, as to which he need make
no statement), at the Execution Time and on the Closing Date, included or
includes an untrue statement of a material fact or omitted or omits to state a

         or an entity "controlled" "by an investment company", as such terms are
         defined in the Investment Company Act.

                  (xviii)  assuming the accuracy of the representations and
         warranties and compliance with the agreements contained herein, no
         registration of the Securities under the Act, and no qualification of
         an indenture under the Trust Indenture Act, are required for the offer
         and sale by the Initial Purchasers of the Securities in the manner
         contemplated by the Purchase Agreement.

                  Such counsel shall also state that while it is not opining as
to factual matters and is not passing upon and does not assume any
responsibility for the accuracy, completeness or fairness of the information
included in the Final Memorandum and assumes the correctness and completeness of
the information included in the Final Memorandum and has made no independent
investigation or verification of such information, except as set forth in
paragraphs (x) and (xi) above, that on the basis of its review of the Final
Memorandum and its participation in its preparation, nothing has come to its
attention that causes it to believe that the Final Memorandum (except for
financial statements and supporting schedules and other financial and reserve
data included therein or omitted therefrom, as to which it need not make any
statement) at the Execution Time and the Closing Time included an untrue
statement of a material fact or omitted to state a material fact necessary in
order to make the statements therein, in the light of the circumstances under
which they were made, not misleading.

                  In rendering such opinion, such counsel may rely (A) as to
matters involving the application of laws of any jurisdiction other than the
State of Delaware, the State of New York or the Federal laws of the United
States, to the extent they deem proper and specified in such opinion, upon the
opinion of other counsel of good standing whom they believe to be reliable and
who are satisfactory to counsel for the Initial Purchasers; and (B) as to
matters of fact, to the extent they deem proper, on certificates of responsible
officers of the Company and public officials. References to the Final Memorandum
in Section 6(a) and Section (b) include any amendment or supplement thereto at
the Closing Date.

                  (c)      The Representatives shall have received from Shearman
& Sterling LLP, counsel for the Initial Purchasers, such opinion or opinions,
dated the Closing Date and addressed to the Representatives, with respect to the
issuance and sale of the Securities, the Indenture, the Registration Rights
Agreement, the Final Memorandum (as amended or supplemented at the Closing Date)
and other related matters as the Representatives may reasonably require, and the
Company shall have furnished to such counsel such documents as they request for
the purpose of enabling them to pass upon such matters.

                  (d)      The Company shall have furnished to the
Representatives a certificate of the Company, signed by the Chief Executive
Officer and the Chief Financial Officer of the

                                       21



Company, dated the Closing Date, to the effect that the signers of such
certificate have carefully examined the Final Memorandum, any amendment or
supplement to the Final Memorandum and this Agreement and that:

                  (i)      the representations and warranties of each of the
         Issuer and the Guarantors in this Agreement are true and correct in all
         material respects on and as of the Closing Date with the same effect as
         if made on the Closing Date, and the Company has complied with all the
         agreements and satisfied all the conditions on its part to be performed
         or satisfied hereunder at or prior to the Closing Date; and

                  (ii)     since the date of the most recent financial
         statements included in the Final Memorandum (exclusive of any amendment
         or supplement thereto), there has been no material adverse change in
         the condition (financial or otherwise), prospects, earnings, business
         or properties of (A) the Company and its subsidiaries, taken as a
         whole, or (B) Arch Western and its subsidiaries, taken as a whole,
         whether or not arising from transactions in the ordinary course of
         business, except as set forth in or contemplated by the Final
         Memorandum (exclusive of any amendment or supplement thereto).

                  (e)      At the Execution Time and at the Closing Date, the
Company shall have requested and caused Ernst & Young LLP to furnish to the
Representatives letters, dated respectively as of the Execution Time and as of
the Closing Date, in form and substance satisfactory to the Representatives,
confirming that they are independent accountants within the meaning of the Act
and the Exchange Act, that they have performed a review of the unaudited interim
consolidated financial information of the Company and Arch Western,
respectively, for the three-month period ended March 31, 2003 and as at March
31, 2003, and stating in effect that:

         and reported on by them, comply in form in all material respects with
         the applicable accounting requirements of the Exchange Act;

         unaudited interim financial information for the three-month period

         specified procedures (but not an examination in accordance with
         generally accepted auditing standards) which would not necessarily
         reveal matters of significance with respect to the comments set forth
         in such letter; a reading of the minutes of the meetings of the
         stockholders, directors and members, as applicable, and of the Audit
         Committee, Finance Committee, Personnel and Compensation Committee and
         Directors Committee of the Company and its subsidiaries; and inquiries
         of certain officials of the Company and Arch Western who have
         responsibility for financial and accounting matters of the Company and
         its subsidiaries and Arch Western and its subsidiaries, as to
         transactions and events subsequent to December 31, 2002, nothing came

                  (iii)    they have performed certain other specified
         procedures as a result of which they determined that certain
         information of an accounting, financial or statistical nature (which is

         from the general accounting records of the Company and its
         subsidiaries) set forth in the Final Memorandum in the Final
         Memorandum, agrees with the accounting records of the Company and its

Representatives, so material and adverse as to make it impractical or
inadvisable to proceed with the offering, sale or delivery of the Securities as
contemplated by the Final Memorandum (exclusive of any amendment or supplement
thereto).

                  (i)      The Securities shall have been designated as

Amended and Restated Revolving Credit Facility , dated as of April 18, 2002, by
and among the Company and the lenders party thereto (the "Company Credit
Facility"), (i) an irrevocable waiver of any Event of Default (as defined in,
and under, the Company Credit Facility) caused, directly or indirectly, by the
transactions contemplated by this Agreement, the Indenture, the Registration
Rights Agreements, the Pledge Agreement and the Final Memorandum and (ii) an
irrevocable consent to the consummation of such transactions; and such waiver
and consent, a copy of which shall have been furnished to the Representatives
prior to the Closing Date, shall be in full force and effect on the Closing
Date.

Representatives may reasonably request.

                  If any of the conditions specified in this Section 6 shall not
have been fulfilled in all material respects when and as provided in this
Agreement, or if any of the opinions and certificates mentioned above or
elsewhere in this Agreement shall not be in all material respects reasonably
satisfactory in form and substance to the Representatives and counsel for the
Initial Purchasers, this Agreement and all obligations of the Initial Purchasers
hereunder may be canceled at, or at any time prior to, the Closing Date by the
Representatives. Notice of such cancellation shall be given to the Company in
writing or by telephone or facsimile confirmed in writing.

                  The documents required to be delivered by this Section 6 will
be delivered at the office of counsel for the Initial Purchasers, at Shearman &
Sterling LLP, 599 Lexington Avenue, New York, New York 10022-6069, on the
Closing Date.

                  7.       Reimbursement of Expenses. If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Initial Purchasers set forth in Section 6 hereof is not
satisfied, because of any termination pursuant to Section 10 hereof or because
of any refusal, inability or failure on the part of the Issuer, the Company or
any Guarantor to perform any agreement herein or comply with any provision
hereof other than by reason of a default by any of the Initial Purchasers, each
of the Issuer, the Company and the Guarantors, jointly and severally, agrees
that it will reimburse the Initial Purchasers severally through Citigroup Global
Markets Inc. on demand for all out-of-pocket expenses (including reasonable fees
and disbursements of counsel) that shall have been incurred by them in
connection with the proposed purchase and sale of the Securities.

                  8.       Indemnification and Contribution. (a) Each of the
Issuer, the Company and the Guarantors, jointly and severally, agrees to
indemnify and hold harmless each Initial Purchaser, the affiliates, directors,
officers, employees and agents of each Initial Purchaser and each person who
controls any Initial Purchaser within the meaning of either the Act or the
Exchange Act against any and all losses, claims, damages or liabilities, joint
or several, to which they or any of them may become subject under the Act, the
Exchange Act or other Federal or state statutory law or regulation, at common
law or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon any untrue statement
or alleged untrue statement of a material fact contained in the Preliminary
Memorandum, the Final Memorandum (or in any supplement or amendment thereto) or
any information provided by the Issuer or any Guarantor to any holder or
prospective purchaser of Securities pursuant to Section 5(h), or in any
amendment thereof or received by it supplement thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading, and
agrees to reimburse each such indemnified party, as incurred, for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that neither the Issuer, nor the Company nor any Guarantor will be liable in any
such case to the extent that any such loss, claim, damage or liability arises
out of or is based

                                       27



upon any such untrue statement or alleged untrue statement or omission or
alleged omission made in the Preliminary Memorandum or the Final Memorandum, or
in any amendment thereof or supplement thereto, in reliance upon and in
conformity with written information furnished to the Issuer, the Company or any
Guarantor by or on behalf of any Initial Purchasers through the Representatives
specifically for inclusion therein. This indemnity agreement will be in addition
to any liability which the Issuer, the Company or any Guarantor may otherwise
have.

                  (b)      Each Initial Purchaser severally and not jointly
agrees to indemnify and hold harmless the Issuer, the Company and the
Guarantors, each of their respective directors, each of their respective
officers, and each person who controls the Issuer, the Company or any Guarantor
within the meaning of either the Act or the Exchange Act, to the same extent as
the foregoing indemnity from each of the Issuer, the Company and the Guarantors
to each Initial Purchaser, but only with reference to written information
relating to such Initial Purchaser furnished to the Issuer, the Company or any
Guarantor by or on behalf of such Initial Purchaser through the Representatives
specifically for inclusion in the Preliminary Memorandum or the Final Memorandum
(or in any amendment or supplement thereto). This indemnity agreement will be in
addition to any liability which any Initial Purchaser may otherwise have. Each
of the Issuer, the Company and the Guarantors acknowledges that the statements
set forth in the paragraph related to stabilization, syndicate covering
transactions and penalty bids on page 127 of the Preliminary Memorandum and the
Final Memorandum, constitute the only information furnished in writing by or on
behalf of the Initial Purchasers for inclusion in the Preliminary Memorandum or
the Final Memorandum (or in any amendment or supplement thereto).

                  (c)      Promptly after receipt by an indemnified party under
this Section 8 of notice of the commencement of any action, such indemnified
party will, if a claim in respect thereof is to be made against the indemnifying
party under this Section 8, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i)
will not relieve it from liability under paragraph (a) or (b) above unless and
to the extent it did not otherwise learn of such action and such failure results
in the forfeiture by the indemnifying party of substantial rights and defenses;
and (ii) will not, in any event, relieve the indemnifying party from any
obligations to any indemnified party other than the indemnification obligation
provided in paragraph (a) or (b) above. The indemnifying party shall be entitled
to appoint counsel of the indemnifying party's choice at the indemnifying
party's expense to represent the indemnified party in any action for which
indemnification is sought (in which case the indemnifying party shall not
thereafter be responsible for the fees and expenses of any separate counsel
retained by the indemnified party or parties except as set forth below);
provided, however, that such counsel shall be satisfactory to the indemnified
party. Notwithstanding the indemnifying party's election to appoint counsel to
represent the indemnified party in an action, the indemnified party shall have
the right to employ separate counsel (including local counsel), and the
indemnifying party shall bear the reasonable fees, costs and expenses of such
separate counsel if (i) the use of counsel chosen by the indemnifying '
represent the indemnified party would present such counsel with a conflict of
interest; (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party; (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to

                                       28



represent the indemnified party within a reasonable time after notice of the
institution of such action; or (iv) the indemnifying party shall authorize the
indemnified party to employ separate counsel at the expense of the indemnifying
party. An indemnifying party will not, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding and does not involve any
statement as to or any admission of fault, culpability or failure to act by or
on behalf of any indemnified party.

                  (d)      In the event that the indemnity provided in paragraph
(a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless
an indemnified party for any reason, the Issuer, the Company, the Guarantors and
the Initial Purchasers agree to contribute to the aggregate losses, claims,
damages and liabilities (including legal or other expenses reasonably incurred
in connection with investigating or defending same) (collectively "Losses") to
which the Issuer, the Company, the Guarantors and one or more of the Initial
Purchasers may be subject in such proportion as is appropriate to reflect the
relative benefits received by the Issuer, the Company and the Guarantors, taken
as a whole, on the one hand and by the Initial Purchasers on the other from the
offering of the Securities; provided, however, that in no case shall any Initial
Purchaser (except as may be provided in any agreement among the Initial
Purchasers relating to the offering of the Securities) be responsible for any
amount in excess of the purchase discount or commission applicable to the
Securities purchased by such Initial Purchaser hereunder. If the allocation
provided by the immediately preceding sentence is unavailable for any reason,
the Issuer, the Company, the Guarantors and the Initial Purchasers shall
contribute in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the Issuer, the Company and the
Guarantor, taken as a whole, on the one hand and of the Initial Purchasers on
the other in connection with the statements or omissions which resulted in such
Losses, as well as any other relevant equitable considerations. Benefits
received by each of the Issuer, the Company and the Guarantors shall be deemed
to be equal to the total net proceeds from the offering (before deducting
expenses) received by the Issuer, the Company and the Guarantors, taken as a
whole, and benefits received by the Initial Purchasers shall be deemed to be
equal to the total purchase discounts and commissions. Relative fault shall be
determined by reference to, among other things, whether any untrue or any
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information provided by the Issuer, the
Company and the Guarantors, taken as a whole, on the one hand or the Initial
Purchasers on the other, the intent of the parties and their relative knowledge,
access to information and opportunity to correct or prevent such untrue
statement or omission. The Issuer, the Company, the Guarantors and the Initial
Purchasers agree that it would not be just and equitable if contribution were
determined by pro rata allocation or any other method of allocation which does
not take account of the equitable considerations referred to above.
Notwithstanding the provisions of this paragraph (d), no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this Section 8, each person who
controls an Initial Purchaser within the meaning of either the Act or the
Exchange Act and each affiliate, director, officer, employee and agent of an
Initial Purchaser shall have the same rights

                                       29



to contribution as such Initial Purchaser, and each person who controls the
Issuer, the Company or any Guarantor within the meaning of either the Act or the
Exchange Act and each respective officer and director of each of the Issuer, the
Company and the Guarantors shall have the same rights to contribution as each of
the Issuer, the Company and the Guarantors, subject in each case to the
applicable terms and conditions of this paragraph (d). The Initial Purchasers'
obligations in this Section 8 to contribute are several in proportion to their
respective underwriting obligations and not joint.

                  9.       Default by an Initial Purchaser. If any one or more
Initial Purchasers shall fail to purchase and pay for any of the Securities
agreed to be purchased by such Initial Purchaser hereunder and such failure to
purchase shall constitute a default in the performance of its or their
obligations under this Agreement, the remaining Initial Purchasers shall be
obligated severally to take up and pay for (in the respective proportions which
the principal amount of Securities set forth opposite their names in Schedule I
hereto bears to the aggregate principal amount of Securities set forth opposite
the names of all the remaining Initial Purchasers) the Securities which the
defaulting Initial Purchaser or Initial Purchasers agreed but failed to
purchase; provided, however, that in the event that the aggregate principal
amount of Securities which the defaulting Initial Purchaser or Initial
Purchasers agreed but failed to purchase shall exceed 10% of the aggregate
principal amount of Securities set forth in Schedule I hereto, the remaining
Initial Purchasers shall have the right to purchase all, but shall not be under
any obligation to purchase any, of the Securities, and if such nondefaulting
Initial Purchasers do not purchase all the Securities, this Agreement will
terminate without liability to any nondefaulting Initial Purchaser, the Issuer,
the Company or any Guarantor. In the event of a default by any Initial Purchaser
as set forth in this Section 9, the Closing Date shall be postponed for such
period, not exceeding five Business Days, as the Representatives shall determine
in order that the required changes in the Final Memorandum or in any other
documents or arrangements may be effected. Nothing contained in this Agreement
shall relieve any defaulting Initial Purchaser of its liability, if any, to the
Issuer, the Company, any Guarantor or any nondefaulting Initial Purchaser for
damages occasioned by its default hereunder.

                  10.      Termination. This Agreement shall be subject to
termination in the absolute discretion of the Representatives, by notice given
to the Company prior to delivery of and payment for the Securities, if at any
time prior to such time (i) trading in the Company's securities shall have been
suspended by the Commission or the New York Stock Exchange or trading in
securities generally on the New York Stock Exchange shall have been suspended or
limited or minimum prices shall have been established on such Exchange; (ii) a
banking moratorium shall have been declared either by Federal or New York State
authorities; or (iii) there shall have occurred any outbreak or escalation of
hostilities, declaration by the United States of a national emergency or war or
other calamity or crisis the effect of which on financial markets is such as to
make it, in the sole judgment of the Representatives, impracticable or
inadvisable to proceed with the offering or delivery of the Securities as
contemplated by the Final Memorandum (exclusive of any amendment or supplement
thereto).

                  11.      Representations and Indemnities to Survive. The
respective agreements, representations, warranties, indemnities and other
statements of each of the Issuer, the Company, the Guarantors or their
respective officers and of the Initial Purchasers set forth in or made pursuant
to this Agreement will remain in full force and effect, regardless of any
investigation

                                       30



made by or on behalf of the Initial Purchasers or the Issuer, the Company, any
Guarantor or any of the officers, directors or controlling persons referred to
in Section 8 hereof, and will survive delivery of and payment for the
Securities. The provisions of Sections 7 and 8 hereof shall survive the
termination or cancellation of this Agreement.

                  12.      Notices. All communications hereunder will be in
writing and effective only on receipt, and, if sent to the Representatives, will

hereof, and, except as expressly set forth in Section 5(h) hereof, no other
person will have any right or obligation hereunder.

                  15.      Counterparts. This Agreement may be executed in one

Each Initial Purchaser represents and agrees that, except as otherwise permitted by Section 4(a) of the Agreement to which this is an exhibit, it has offered and sold the Securities, and will offer and sell the Securities, (i) as part of their distribution at any time; and (ii) otherwise until 40 days after the later of the commencement of the offering and the Closing Date, only in accordance with Rule 903 of Regulation S under the Act.

Each Initial Purchaser agrees that, at or prior to the confirmation of sale of Securities (other than a sale of Securities pursuant to Section 4(a) of the Agreement to which this is an exhibit), it shall have sent to each distributor, dealer or person receiving a selling concession, fee or other remuneration that purchases Securities from it during the distribution compliance period a confirmation or notice to substantially the following effect: "The Securities covered hereby have not been registered under the U.S. Securities Act of 1933 (the "Act") and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of their distribution at any time or (ii) otherwise until 40 days after the later of the commencement of the offering and [specify closing date of the offering], except in either case in accordance with Regulation S or Rule 144A under the Act.

         4.       Purposes.

                  The Company shall have all powers now or hereafter conferred
or permitted by the laws of the State of Delaware on limited liability companies
formed under the Act and, subject to the terms of this Agreement, may do any and
all lawful acts or things that are necessary, appropriate, incidental or
convenient for the furtherance and accomplishment of the purposes of the
Company. Without limiting the generality of the foregoing, the Company may enter
into, deliver and perform all contracts, agreements and other undertakings and
engage in all activities and transactions as may be necessary or appropriate to
carry out its purposes.



         5.       Registered Office and Agent.

the registered agent of the Company for service of process on the Company in the
State of Delaware is The Corporation Trust Company, Corporation Trust Center,

         6.       Principal Executive Office.

                  The principal executive office of the Company shall be located
at, and the Company's business shall be conducted from, such place or places as
the Members may designate from time to time. The initial principal executive
office of the Company shall be located at One CityPlace Drive, Suite 300, St.
Louis, Missouri 63141.

         7.       Member.

                  The name, present mailing address and percentage interest of
the Member ("membership interest") is set forth on Schedule A. The membership
interest created hereunder as set forth on Schedule A are securities as defined
in Section 8-103(c) of the Uniform Commercial Code as adopted in Delaware. The
business and affairs of the Company shall be managed by a Board of Directors
selected, and subject to removal with or without cause, by the Member which
shall have all powers and rights necessary, appropriate or advisable to
effectuate and carry out the purposes and business of the Company. The Board of
Directors shall include those individuals listed on Schedule B attached hereto
which schedule may be revised by the Member at any time or from time to time.
The Directors will be deemed "Managers" within the meaning of the Act. Each
Member and Director is hereby designated as an authorized person, within the
meaning of the Act, to execute, deliver and file the certificate of formation of
the Company (and any amendments and/or restatements thereof); provided that,
except to the extent specifically referenced in this Agreement, no Member shall
have the authority to bind or otherwise act for the Company. Except for the
power to select and remove members of the Board of Directors, the Member shall
have no power or authority with respect to the operations of the Company and
shall only have the specific rights and privileges set forth herein or as
provided by applicable law.

         8.       Board of Directors

                  Meetings of the Board of Directors shall be held at the
principal place of business of the Company or at any other place that a majority
of the directors determines. In the alternative, meetings may be held by
conference telephone, provided that each director can hear the others. The
presence of a majority of the directors shall constitute a quorum for the
transaction of business. The vote of a majority of the directors present at a
meeting at which a quorum is present shall be the act of the Board of Directors.
The Board of Directors may also make decisions, without



holding a meeting, by written consent of all of the directors. In connection
with the management of the business and affairs of the Company, the Board of
Directors and officers of the Company shall execute, deliver and file any
certificates (and any amendments and/or restatements thereof) necessary for the
Company to qualify to do business in a jurisdiction in which the Company may
wish to conduct business. The execution by one Director or by one officer, as
applicable, or by one Member, as applicable, of any of the foregoing
certificates (and any amendments and/or restatements thereof) shall be
sufficient.

         9.       Officers.

                  The Managers may, from time to time as they deem advisable,
appoint officers of the Company (the "Officers") and assign in writing titles
(including, without limitation, President, Vice President, Secretary, and
Treasurer) to any such person. Unless the Managers decide otherwise, if the
title is one commonly used for officers of a business corporation formed under
the Delaware General Corporation Law, the assignment of such title shall
constitute the delegation to such person of the authorities and duties that are
normally associated with that office. The initial officers are listed on
Schedule C attached hereto which schedule may be revised by either the Member of
Managers at any time or from time to time. Any delegation pursuant to this
Section 9 may be revoked at any time by the Managers.

         10.      Limited Liability.

                  Except as otherwise provided by the Act, the debts,
obligations and liabilities of the Company, whether arising in contract, tort or
otherwise, shall be solely the debts, obligations and liabilities of the
Company, and the Member shall not be obligated personally for any such debt,
obligation or liability of the Company solely by reason of being a member of the
Company.

         11.      Capital Contributions.

                  The Member is deemed admitted as the Member of the Company
upon its execution and delivery of this Agreement. The Member will contribute
the amount of United States Dollars to the Company as listed on Schedule A
attached hereto.

         12.      Additional Contributions.

                  The Member is not required to make any additional capital
contribution to the Company. However, a Member may make additional capital
contributions to the Company at such times and in such amounts as determined by
the Member.

         13.      Allocation of Profits and Losses.

                  The Company's profits and losses shall be allocated to the
Member.



         14.      Distributions.

                  Distributions shall be made to the Member at the times and in
the aggregate amounts determined by the Member. Notwithstanding any provision to
the contrary contained in this Agreement, the Company shall not make a
distribution to any Member on account of its interests in the Company if such
distribution would violate Section 18-607 of the Act or other applicable law.

         15.      Other Business.

                  The Member may engage in or possess an interest in other
business ventures (unconnected with the Company) of every kind and description,
independently or with others. The Company shall not have any rights in or to
such independent ventures or the income or profits therefrom by virtue of this
Agreement.

         16.      Exculpation and Indemnification.

                  No Member, no Affiliate of a member, nor any Manager, Officer,
employee or agent of the Company ("Indemnified Party") shall be liable to the
Company, or any other person or entity who has an interest in the Company, for
any loss, damage or claim incurred by reason of any act or omission performed or
omitted by such Member or Officer in good faith on behalf of the Company and in
a manner reasonably believed to be within the scope of the authority conferred
on such Member or Officer by this Agreement, unless such act or omission
constituted bad faith, gross negligence, fraud or willful misconduct. To the
full extent permitted by applicable law, an Indemnified Party shall be entitled
to indemnification from the Company for any loss, damage or claim incurred by an
Indemnified Party by reason of any act or omission performed or omitted by an
Indemnified Party in good faith on behalf of the Company and in a manner
reasonably believed to be within the scope of the authority conferred on an
Indemnified Party by this Agreement, unless such act or omission constituted bad
faith, gross negligence, fraud or willful misconduct; provided, however, that
any indemnity under this Section 16 shall be provided out of and to the extent
of Company assets only, and no Member shall have personal liability on account
thereof.

         17.      Assignments.

                  A Member may assign in whole or in part its limited liability
company interest with the written consent of all other Members. If a Member
transfers all of its interest in the Company pursuant to this Section, the
transferee shall be admitted to the Company upon its execution of an instrument
signifying its agreement to be bound by the terms and conditions of this
Agreement. Such admission shall be deemed effective immediately prior to the
transfer, and, immediately following such admission, the transferor Member shall
cease to be a member of the Company.

         18.      Resignation.

                  A Member may resign from the Company with the written consent
of the Member. If a Member is permitted to resign pursuant to this Section, an
additional



member shall be admitted to the Company, subject to Section 17, upon its
execution of an instrument signifying its agreement to be bound by the terms and
conditions of this Agreement. Such admission shall be deemed effective
immediately prior to the resignation, and, immediately following such admission,
the resigning Member shall cease to be a member of the Company.

         19.      Admission of Additional Members.

                  One or more additional members of the Company may be admitted
to the Company with the written consent of all of the Member.

         20.      Dissolution.

                  a.       The Company shall dissolve, and its affairs shall be
wound up upon the first to occur of the following: (i) the written consent of
the Member, (ii) the retirement, resignation or dissolution of the Member or the
occurrence of any other event which terminates the continued membership of the
Member in the Company unless the business of the Company is continued in a
manner permitted by the Act, or (iii) the entry of a decree of judicial
dissolution under Section 18-802 of the Act.

                  b.       The bankruptcy of the Member will not cause the
Member to cease to be a member of the Company and upon the occurrence of such an
event, the business of the Company shall continue without dissolution.

                  c.       In the event of dissolution, the Company shall
conduct only such activities as are necessary to wind up its affairs (including
the sale of the assets of the Company in an orderly manner), and the assets of
the Company shall be applied in the manner, and in the order of priority, set
forth in Section 18-804 of the Act.

         21.      Separability of Provisions.

                  Each provision of this Agreement shall be considered separable
and if for any reasons any provision or provisions herein are determined to be
invalid, unenforceable or illegal under any existing or future law, such
invalidity, unenforceability or illegality shall not impair the operation of or
affect those portions of this Agreement which are valid, enforceable and legal.

         22.      Terms Generally.

                  The definitions in this Agreement shall apply equally to both
the singular and plural forms of the terms defined. Whenever the context may

Therefore, notwithstanding any other provision of this Section 3 (other than the Regulatory Allocations), the Managing Member shall make such offsetting allocations of Company income, gain, loss or deduction in whatever manner it determines appropriate so that, after such offsetting allocations are made, each Member's Capital Account balance is, to the extent possible, equal to the Capital Account balance such Member would have had if the Regulatory Allocations were not part of the Agreement and all Company items were allocated pursuant to Sections 3.1, 3.2 and 3.3(i). In exercising its discretion under this Section 3.4, the Managing Member shall take into account future Regulatory Allocations under Sections 3.3(a) and 3.3(b) that, although not yet made, are likely to offset other Regulatory Allocations previously made under Section 3.3(e) and 3.3(g). 3.5 Other Allocation Rules.

In accordance with Code Section 704(c) and the Regulations thereunder, income, gain, loss, and deduction with respect to any Property contributed to the capital of the Company shall, solely for tax purposes, be allocated among the Members so as to take account of any variation between the adjusted basis of such Property to the Company for federal income tax purposes and its initial Gross Asset Value (computed in accordance with the definition of Gross Asset Value). In the event the Gross Asset Value of any Company asset is adjusted pursuant to subparagraph (ii) of the definition of Gross Asset Value, subsequent allocations of income, gain, loss, and deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset for federal income tax purposes and its Gross Asset Value in the same manner as under Code Section 704(c) and the Regulations thereunder. With respect to the - 24 - allocations under this Section 3.6, for purposes of Code Section 704(c), the Company shall employ the method prescribed in Section 1.704-3(b) of the Regulations (the "traditional method") or any equivalent successor Regulations.

If the Managing Member shall cease to be a Member, then the Member with the greatest Common Percentage Interest shall thereafter act as the Tax Matters Partner. The Tax Matters Partner shall take reasonable action to cause each other Member to be treated as a "notice partner" within the meaning of Section 6231(a)(8) of the Code. All reasonable expenses incurred by a Member while acting in its capacity as Tax Matters Partner shall be paid or reimbursed by the Company.

Unless otherwise determined by the Managing Member, all such income or franchise tax returns of the Company shall be prepared by the Accountants. The cost of preparation of any returns by the Accountants or other outside preparers shall be borne by the Company. Except as otherwise expressly provided herein, all elections required or permitted to be made by the Company under the Code (or applicable state or local tax law) shall be made in such manner as may be determined by the Managing Member to be in the best interests of the Members as a group.

At any time after such schedule and information have been provided, upon at least five Business Days' notice from a Member, the Company shall also provide each Member with a reasonable opportunity during ordinary business hours to review and make copies of all work papers related to such schedule and information or to any return prepared under paragraph (b) above. The Tax Matters Partner shall also cause to be provided to each Member, at the time that the quarterly financial statements are required to be delivered pursuant to Section 6.2(b)(ii) above, an estimate of each Member's share of all items of income, gain, loss, deduction and credit of the Company for the fiscal quarter just completed and for the Fiscal Year to date for federal income tax purposes.

Each Member and each Affiliate of a Member agrees to take any action pursuant to this Section 6.3(d) reasonably requested by ARCO Member. The Company and each Member will not file any protective claim or election in connection with these matters unless (i) directed to do so by ARCO or (ii) they receive ARCO's prior written consent to such filing, which consent will not be unreasonably withheld. SECTION 7 DISPOSITIONS OF INTERESTS 7.1 Restriction on Dispositions. Except as otherwise permitted by this Agreement, no Member shall Dispose of all or any portion of its Interest. 7.2 Permitted Transfers. Subject to the conditions and restrictions set forth in Section 7.3, a Member may at any time Transfer all or any portion of its Interest (a) to any Controlled Affiliate of such Member, (b) in connection with a Permitted Transaction, (c) to the administrator or trustee of such Member to whom such Interest is transferred in an Involuntary Bankruptcy, (d) pursuant to and in compliance with Section 7.4 or (e) with the prior written consent of the other Members (each a "Permitted Transfer"), provided that unless approved by all Members, no Transfer of a Member's Interest (other than pursuant to Section 7.4) will be a Permitted Transfer if such Transfer would reasonably likely result in (y) a breach of any covenant, representation or other agreement in any - 33 - instrument with respect to the Company Debt or any Successor Debt; or (z) otherwise materially adversely affect the creditworthiness of the Company. After any Permitted Transfer, the Transferred Interest shall continue to be subject to all the provisions of this Agreement, including the provisions of this Section 7 with respect to the Disposition of Interests. Except in the case of a Transfer of a Member's entire Interest made in compliance herewith, no Member shall withdraw from the Company, except with the consent of the Managing Member. The withdrawal of a Member, whether or not permitted, shall not relieve the withdrawing Member of its obligations under Section 10.7 and shall not relieve such Member or any of its Affiliates of its obligations under, or result in a termination of or otherwise affect, any agreement between the Company and such Member or Affiliate then in effect, except to the extent provided therein. 7.3 Conditions to Permitted Transfers. A Transfer shall not be treated as a Permitted Transfer unless and until the following conditions are satisfied: (a) Except in the case of a Transfer involuntarily by operation of law, the transferor and transferee shall execute and deliver to the Company such documents as may be necessary or appropriate in the opinion of counsel to the Company to effect such Transfer. In the case of a Transfer of Interests involuntarily by operation of law, the Transfer shall be confirmed by presentation to the Company of legal evidence of such Transfer, in form and substance satisfactory to counsel to the Company. In all cases, the Company shall be reimbursed by the transferor and/or transferee for all costs and expenses that it reasonably incurs in connection with such Transfer (including reasonable attorneys' fees and expenses, but excluding the portion of the costs of determining Net Equity that are to be borne by the Company as provided in Section 7.4(d)); (b) Except in the case of a Transfer involuntarily by operation of law, the transferee of an Interest (other than, with respect to clause (A) below, a transferee that was a Member prior to the Transfer) shall, by written instrument in form and substance reasonably satisfactory to the Managing Member (and, in the case of clause (B) below, the transferor Member), (A) accept and adopt the terms and provisions of this Agreement, including this Section 8, and (B) assume the obligations of the transferor Member under this Agreement with respect to the Transferred Interest. The transferor Member shall be released from all such assumed obligations except (x) as otherwise provided in Section 10.7, (y) those obligations or liabilities of the transferor Member arising out of a breach of this Agreement and (z) in the case of a transfer to any Person other than a Member or any of its Controlled Affiliates, those obligations or liabilities of the transferor Member based on events occurring, arising or maturing prior to the date of Transfer; - 34 - (c) Except in the case of a Transfer involuntarily by operation of law, the transferor and its Affiliates will be obligated to sell to the transferee, and the transferee will be obligated to buy from the transferor and its Affiliates, all Member Loans of the Company held directly or indirectly by the transferor or an Affiliate thereof. If the transferee is a Member or a Controlled Affiliate thereof, the terms of such purchase will include those provided in Section 2.5; (d) Except in the case of a Transfer involuntarily by operation of law, if required by the Managing Member, the transferee shall deliver to the Company an opinion, satisfactory in form and substance to the Managing Member, of counsel reasonably satisfactory to the Managing Member to the effect that the Transfer of the Interest is in compliance with applicable state and federal securities laws; (e) Except in the case of a Transfer involuntarily by operation of law, if required by the Managing Member, the transferee (other than a transferee that was a Member prior to the Transfer) shall deliver to the Company evidence of the authority of such Person to become a Member and to be bound by all of the terms and conditions of this Agreement, and the transferee and transferor shall each execute and deliver such other instruments as the Managing Member reasonably deems necessary or appropriate to effect, and as a condition to, such Transfer, including amendments to the Certificate or any other instrument filed with the State of Delaware or any other state or governmental agency; (f) Unless otherwise approved by the Managing Member, no Transfer of an Interest shall be made except upon terms which would not, in the opinion of counsel chosen by the Managing Member, result in the termination of the Company within the meaning of Section 708 of the Code or cause the application of the rules of Sections 168(g)(1)(B) and 168(h) of the Code or similar rules to apply to the Company. If the immediate Transfer of such Interest would, in the opinion of such counsel, cause a termination within the meaning of Section 708 of the Code, then if, in the opinion of such counsel, the following action would not precipitate such termination, the transferor Member shall be entitled (or required, as the case may be) (i) immediately to Transfer only that portion of its Interest as may, in the opinion of counsel to the Company, be transferred without causing such a termination and (ii) to enter into an agreement to Transfer the remainder of its Interest, in one or more Transfers, at the earliest date or dates on which such Transfer or Transfers may be effected without causing such termination. The purchase price for the Interest shall be allocated between the immediate Transfer and the deferred Transfer or Transfers pro rata on the basis of the percentage of the aggregate Interest being transferred, each portion to be payable when the respective Transfer is consummated, unless otherwise agreed by the parties to the Transfer. In the case of a Transfer by one Member to another Member, the deferred purchase price shall be deposited in an interest-bearing escrow account unless another method of securing the payment thereof is agreed upon by the transferor Member and the transferee Member(s). In determining whether a particular proposed Transfer will result in a termination of the Company, counsel to the Company shall take into account the existence of prior written commitments to Transfer made pursuant to this Agreement and such commitments shall always be given precedence over subsequent proposed Transfers; - 35 - (g) The transferor or transferee shall furnish the Company with the transferee's taxpayer identification number, sufficient information to determine the transferee's initial tax basis in the Interest transferred, and any other information reasonably necessary to permit the Company to file all required federal and state tax returns and other legally required information statements or returns. Without limiting the generality of the foregoing, the Company shall not be required to make any distribution otherwise provided for in this Agreement with respect to any transferred Interest until it has received such information; and (h) Except in the case of a Transfer of an Interest involuntarily by operation of law, the transferor and transferee shall provide the Company with an opinion of counsel, which opinion of counsel shall be reasonably satisfactory to the other Members, to the effect that such Transfer will not cause the Company to become taxable as a corporation for federal income tax purposes. Upon completion of any Permitted Transfer and compliance with the provisions of this Section 7.3, the transferee of the Interest (if not already a Member) shall be admitted as a Member without any further action. 7.4 Put and Call Rights. (a) ARCO Member Put Right. At any time after the seventh anniversary of the Closing Date (as defined in the Purchase and Sale Agreement), ARCO Member shall have the right, upon providing at least 60 days' advance written notice to Arch Member (a "Put Notice"), to require Arch Member to purchase all or part of ARCO Member's Interest. The price at which ARCO Member's Interest will be so purchased and sold shall be determined by mutual agreement between Arch Member and ARCO Member. If such price is not so agreed upon within 60 days after the date of the Put Notice, such price shall be equal to the sum of (x) if the Preferred Capital Amount or any part thereof is to be sold, an amount equal to all or such portion of the Preferred Capital Amount and any accrued and unpaid Preferred Return thereon, and (y) if the ARCO Member Common Percentage Interest or any part thereof is to be sold, the Net Equity of such Common Percentage Interest or part thereof determined as of the last day of the fiscal quarter immediately preceding the fiscal quarter in which the Put Notice was given. No Damages or other amounts shall be payable to ARCO Member under the Tax Sharing Agreement in connection with the exercise by ARCO Member of its rights under this Section 7.4(a). (b) Arch Member Call Rights. At any time after the date hereof, Arch Member shall have the right, upon providing at least 60 days' advance written notice (a "Call Notice") to ARCO Member, to purchase or to cause another person to purchase all, but not less than all, of the ARCO Member Interest at a price equal to the sum of (i) the Preferred Capital Amount and any accrued and unpaid Preferred Return thereon, and (ii) the Net Equity of the ARCO Member Common Percentage Interest determined as of the last day of the fiscal quarter immediately preceding the fiscal quarter in which the Call Notice was given, together with Damages (if any) determined as set forth in the Tax Sharing Agreement. - 36 - (c) Post 2013 Call Right. At any time after January 1, 2013, Arch Member shall have the right, upon providing at least 60 days advance written Call Notice to ARCO Member, to purchase all of the ARCO Member Interest and any Interest of ARCO Member Transferred at a price equal to the Net Equity of the ARCO Member Interest and/or Transferred Interest determined as of the last day of the fiscal quarter immediately preceding the fiscal quarter in which the Call Notice was given. No Damages or other amounts shall be payable to ARCO Member under the Tax Sharing Agreement in connection with the exercise by Arch Member of its rights under this Section 7.4(c). (d) Terms of Purchase; Closing. Unless Arch Member and ARCO Member otherwise agree, the closing of the purchase and sale of ARCO Member's Interest shall occur at the principal office of the Company at 10:00 a.m. (local time at the place of the closing) on the first Business Day occurring on or after the 60th day following the last day of the required advance written notice period (subject to the provisions of Section 7.7). At the closing, Arch Member shall pay to ARCO Member, by cash or other immediately available funds, the purchase price for ARCO Member's Interest and ARCO Member shall deliver to Arch Member good title, free and clear of any liens, claims, encumbrances, security interests or options (other than those created by this Agreement and those securing financing obtained by the Company), to the ARCO Member's Interest thus purchased. At the closing, the Members shall execute such documents and instruments of conveyance as may be necessary or appropriate to effectuate the transactions contemplated hereby, including the Transfer of the ARCO Member's Interest to Arch Member and the assumption by Arch Member of ARCO Member's obligations with respect to the ARCO Member's Interest Transferred to Arch Member. The Company and each Member shall bear its own costs of such Transfer and closing, including attorneys' fees and filing fees. The cost of determining Net Equity shall be borne by the Company. 7.5 Net Equity. The "Net Equity" of a Member's Interest, as of any day, shall be the amount that would be distributed to such Member in liquidation of the Company pursuant to Section 8 if (a) all of the Company's business and assets were sold substantially as an entirety for Gross Appraised Value, (b) the Company paid its accrued, but unpaid, liabilities and established reserves pursuant to Section 8.2 for the payment of reasonably anticipated contingent or unknown liabilities and (c) the Company distributed the remaining proceeds to the Members in liquidation, all as of such day, provided that in determining such Net Equity, no reserve for contingent or unknown liabilities shall be taken into account if such Member (or its successor in interest) agrees to indemnify the Company and all other Members for that portion of any such reserve as would be treated as having been withheld pursuant to Section 8.3 from the distribution such Member would have received pursuant to Section 8.2 if no such reserve were established. The Net Equity of a Member's Interest shall be determined, without audit or certification, from the books and records of the Company by the Accountants. The Net Equity of a Member's - 37 - Interest shall be determined within 30 days of the day upon which the Accountants are apprised in writing of the Gross Appraised Value of the Company's business and assets, and the amount of such Net Equity shall be disclosed to the Company and each of the Members by written notice ("Net Equity Notice"). The Net Equity determination of the Accountants shall be final and binding in the absence of a showing of manifest error. 7.6 Gross Appraised Value. "Gross Appraised Value," as of any day, means the price at which a willing seller would sell, and a willing buyer would buy, the business and assets of the Company, free and clear of all liens and encumbrances, substantially as an entirety and as a going concern in a single arm's-length transaction for cash, without time constraints and without being under any compulsion to buy or sell. In connection with provisions of this Agreement that require a determination of Gross Appraised Value, the Managing Member shall appoint an appraiser (the "First Appraiser") and the affected Member or Members shall appoint a second appraiser (the "Second Appraiser"). If the Second Appraiser is not timely designated, the determination of the Gross Appraised Value shall be made by the First Appraiser. The First Appraiser, or each of the First Appraiser and the Second Appraiser if the Second Appraiser is timely designated, shall submit its determination of the Gross Appraised Value to the Company, the Members and the Accountants within 45 days of the date of its selection (or the selection of the Second Appraiser, as applicable). If there are two (2) Appraisers and their respective determinations of the Gross Appraised Value vary by less then ten percent of the higher determination, the Gross Appraised Value shall be the average of the two determinations. If such determinations vary by ten percent or more of the higher determination, the two Appraisers shall promptly designate a third appraiser (the "Third Appraiser"). Neither the Company nor any Member shall provide, and the First Appraiser and Second Appraiser shall be instructed not to provide, any information to the Third Appraiser as to the determinations of the First Appraiser and the Second Appraiser or otherwise influence such Third Appraiser's determination in any way. The Third Appraiser shall submit its determination of the Gross Appraised Value to the Company, the Members and the Accountants within 45 days of the date of its selection. The Gross Appraised Value shall be equal to the average of the two closest of the three determinations, provided that, if the difference between the highest and middle determinations is no more than 105% and no less than 95% of the difference between the middle and lowest determinations, then the Gross Appraised Value shall be equal to the middle determination. The determination of the Gross Appraised Value in accordance with the foregoing procedure shall be final and binding on the Company and each Member. If any Appraiser is only able to provide a range in which Gross Appraised Value would exist, the average of the highest and lowest value in such range shall be deemed to be such Appraiser's determination of the Gross Appraised Value of the Company's business and assets. The Third Appraiser selected pursuant to the provisions of this Section shall be an investment banking firm - 38 - or other qualified Person with prior experience in appraising businesses comparable to the business of the Company. 7.7 Extension of Time. If any transfer of a Member's Interest in accordance with this Section 7 requires the consent, approval, waiver, or authorization of any government department, board, bureau, commission, agency or instrumentality as a condition to the lawful and valid Transfer of such Member's Interest to the proposed transferee thereof, then each of the time periods provided in this Section 7, as applicable, for the closing of such Transfer shall be suspended for the period of time during which any such consent, approval, waiver, or authorization is being diligently pursued; provided, however, that in no event shall the suspension of any time period pursuant to this Section 7.7 extend for more than 365 days. Each Member agrees to use its diligent efforts to obtain, or to assist the affected Member or the Managing Member in obtaining, any such consent, approval, waiver, or authorization and shall cooperate and use its diligent efforts to respond as promptly as practicable to all inquiries received by it, by the affected Member or by the Managing Member from any government department, board, bureau, commission, agency or instrumentality for initial or additional information or documentation in connection therewith. 7.8 Tagalong Rights. In the event that the Managing Member proposes to Transfer all or any portion of its Common Percentage Interest to any person other than a Controlled Affiliate of the Managing Member (a "Tagalong Transaction"), the Tagalong Transaction shall not be permitted hereunder unless the proposed transferee ("Tagalong Purchaser") offers to purchase the entire Interest of ARCO Member if ARCO Member desires to sell such Interest to the Tagalong Purchaser at the same price and on the same terms and conditions as the Tagalong Purchaser has offered to the Managing Member (the "Transferring Member") for its Common Percentage Interest, plus an amount equal to the Preferred Capital Amount and any accrued but unpaid Preferred Return thereon to the date of purchase. Prior to effecting any Tagalong Transaction, the Transferring Member shall deliver to ARCO Member a binding, irrevocable offer (the "Tagalong Offer") by the Tagalong Purchaser to purchase the entire Interest of ARCO Member at the same price and on the same terms and conditions as the Tagalong Purchaser has offered to the Transferring Member (the "Tagalong Notice") for its Common Percentage Interest, plus an amount equal to the Preferred Capital Amount and any accrued but unpaid Preferred Return thereon to the date of purchase. The "Tagalong Offer" shall be irrevocable for a period (the "Tagalong Period") ending at 11:59 p.m., local time at the Company's principal place of business on the 30th day following the date of the Tagalong Notice. At any time during the Tagalong Period, ARCO Member may accept the Tagalong Offer as to the entire amount of its Interest by giving written notice of such acceptance to the Tagalong Purchaser. The Tagalong Purchaser's purchase of the Interest of ARCO Member shall occur at the closing of the Tagalong Transaction (provided such closing is not earlier than 30 Business Days after the Tagalong Notice), subject to Section 7.7. - 39 - 7.9 Prohibited Dispositions. Any purported Disposition of all or any part of an Interest that is not a Permitted Transfer shall be null and void and of no force or effect whatever; provided that, if the Company is required to recognize a Disposition that is not a Permitted Transfer (or if the Managing Member, in its sole discretion, elects to recognize a Disposition that is not a Permitted Transfer), the Interest Disposed of shall be strictly limited to the transferor's rights to allocations and distributions as provided by this Agreement with respect to the Transferred Interest, which allocations and distributions may be applied (without limiting any other legal or equitable rights of the Company) to satisfy any debts, obligations, or liabilities for damages that the transferor or transferee of such Interest may have to the Company. 7.10 Representations Regarding Acquisitions of Interests. Each Member hereby represents and warrants to the Company and the other Members that such Member's acquisition of Interests hereunder is made as principal for such Member's own account and not for resale or distribution of such Interests. 7.11 Distributions and Allocations in Respect of Transferred Interests. If any Interest is Transferred during any Allocation Year in compliance with the provisions of this Section 7, Profits, Losses, each item thereof, and all other items attributable to the Transferred Interest for such Fiscal Year shall be divided and allocated between the transferor and the transferee by taking into account their varying Percentage Interests during the Fiscal Year in accordance with Code Section 706(d), using any conventions permitted by law and selected by the Managing Member. All distributions on or before the date of such Transfer shall be made to the transferor, and all distributions thereafter shall be made to the transferee. Solely for purposes of making such allocations and distributions, the Company shall recognize such Transfer not later than the end of the calendar month during which it is given notice of such Transfer, provided that, if the Company is given notice of a Transfer at least ten Business Days prior to the Transfer, the Company shall recognize such Transfer as of the date of such Transfer, and provided further that if the Company does not receive a notice stating the date such Interest was Transferred and such other information as the Managing Member may reasonably require within 30 days after the end of the Fiscal Year during which the Transfer occurs, then all such items shall be allocated, and all distributions shall be made, to the Person who, according to the books and records of the Company, was the owner of the Interest on the last day of such Fiscal Year. Neither the Company nor the Managing Member shall incur any liability for making allocations - 40 - and distributions in accordance with the provisions of this Section 7.11, whether or not the Managing Member or the Company has knowledge of any Transfer of ownership of any Interest. SECTION 8 DISSOLUTION AND WINDING UP 8.1 Liquidating Events. The Company shall dissolve and commence winding up and liquidating upon the first to occur of any of the following ("Liquidating Events"): (i) The sale of all or substantially all of the Property; and (ii) The agreement of the Members to dissolve, wind up, and liquidate the Company. The Members hereby agree that, notwithstanding any provision of the Act, the Company shall not dissolve prior to the occurrence of a Liquidating Event. The event described in Section 8.1(ii) shall not constitute a Liquidating Event until such time as the Company is otherwise required to dissolve, and commence winding up and liquidating. 8.2 Winding Up. Upon the occurrence of a Liquidating Event, the Company shall continue solely for the purposes of winding up its affairs in an orderly manner, liquidating its assets, and satisfying the claims of its creditors and Members and no Member shall take any action that is inconsistent with, or not appropriate for, the winding up of the Company's business and affairs. To the extent not inconsistent with the foregoing, this Agreement shall continue in full force and effect until such time as the Company's Property has been distributed pursuant to this Section 8.2 and the Certificate has been canceled in accordance with the Act. The Managing Member shall be responsible for overseeing the winding up and dissolution of the Company, shall take full account of the Company's liabilities and Property, shall cause the Company's Property to be liquidated as promptly as is consistent with obtaining the fair value thereof, and shall cause the proceeds therefrom, to the extent sufficient therefor, to be applied and distributed in the following order: - 41 - (a) First, to the payment of all of the Company's debts and liabilities (other than Member Loans) to creditors other than the Members and to the payment of the expenses of liquidation; (b) Second, to the payment of all Member Loans and all of the Company's debts and liabilities to the Members in the following order and priority: (1) first, to the payment of all debts and liabilities owed to any Member other than in respect of Member Loans; (2) second, to the payment of all accrued and unpaid interest on Member Loans, such interest to be paid to each Member and its Affiliates (considered as a group) pro rata in proportion to the interest owed to each such group; and (3) third, to the payment of the unpaid principal amount of all Member Loans, such principal to be paid to each Member and its Affiliates (considered as a group) pro rata in proportion to the outstanding principal owed to each such group; (c) Third, in an amount equal to the unpaid cumulative Preferred Return; (d) Fourth, in an amount equal to the Preferred Capital Amount; (e) The balance, if any, to the Members in accordance with their Capital Accounts, after giving effect to all contributions, distributions and allocations for all periods; (f) In the discretion of the Managing Member, a pro rata portion of the distributions that would otherwise be made to the Members pursuant to this Section 8.2 may be: (1) distributed to a trust established for the benefit of the Members for the purposes of liquidating Company assets, collecting amounts owed to the Company, and paying any contingent or unforeseen liabilities or obligations of the Company. The assets of any such trust shall be distributed to the Members from time to time, in the reasonable discretion of the Managing Member, in the same proportions as the amount distributed to such trust by the Company would otherwise have been distributed to the Members pursuant to this Section 8.2; or (2) withheld to provide a reasonable reserve for Company liabilities (contingent or otherwise) and to reflect the unrealized portion of any installment obligations owed to the Company, provided that such withheld amounts shall be distributed to the Members as soon as practicable; and (g) Any such distributions to the Members in respect of their Capital Accounts shall be made in accordance with the time requirements set forth in Treas. Regs. Section 1.704-1(b)(2)(ii)(b)(2). - 42 - Each Member and each of its Affiliates (as to Member Loans only) agrees that by accepting the provisions of this Section 8.2 setting forth the priority of the distribution of the assets of the Company to be made upon its liquidation, such Member or Affiliate expressly waives any right which it, as a creditor of the Company, might otherwise have under the Act to receive distributions of assets pari passu with the other creditors of the Company in connection with a distribution of assets of the Company in satisfaction of any liability of the Company, and hereby subordinates to said creditors any such right. Notwithstanding the foregoing, in the event that the Managing Member shall determine that an immediate sale of part of all the Property would cause undue loss to the Members, or in the event that the Managing Member determines that it would be in the best interests of the Members to distribute the Property to the Members in-kind (which distributions do not, as to the in-kind portions, have to be in the same proportions as they would be if cash were distributed, but all such in-kind distributions shall be equalized, to the extent necessary, with cash), then the Managing Member may either defer liquidation of, and withhold from distribution for a reasonable time, any of the Property except that necessary to satisfy the Company's debts and obligations, or distribute the Property to the Members in-kind. 8.3 Deemed Distribution and Recontribution. Notwithstanding any other provision of this Section 8, in the event the Company is liquidated within the meaning of Section 1.704-1(b)(2)(ii)(g) of the Regulations but no Liquidating Event has occurred, the Property shall not be liquidated, the Company's liabilities shall not be paid or discharged, and the Company's affairs shall not be wound up. Instead, solely for federal income tax purposes, the Company shall be deemed to have distributed the Property in kind to the Members, who shall be deemed to have assumed and taken subject to all Company liabilities, all in accordance with their respective Capital Accounts. Immediately thereafter, the Members shall be deemed to have recontributed the Property in kind to the Company, which shall be deemed to have assumed and taken subject to all such liabilities. 8.4 Rights of Members. Except as otherwise provided in this Agreement, (a) each Member shall look solely to the assets of the Company for the return of its Capital Contributions and shall have no right or power to demand or receive property other than cash from the Company, and (b) no Member shall have priority over any other Member as to the return of its Capital Contributions, distributions, or allocations. If, after the Company ceases to exist as a legal entity, a Member is required to make a payment to any Person on account of any activity carried on by the Company, such paying - 43 - Member shall be entitled to reimbursement from each other Member consistent with the manner in which the economic detriment of such payment would have been borne had the amount been paid by the Company immediately prior to its cessation. 8.5 Notice of Dissolution. In the event a Liquidating Event occurs, the Managing Member shall, within 30 days thereafter, provide written notice thereof to each of the Members. 8.6 Deemed Sale and Allocation. Upon a distribution in kind of Company Property, such Property shall be deemed to be sold for the fair market value thereof for purposes of making allocations hereunder. SECTION 9 DISPUTE RESOLUTION 9.1 Dispute Resolution; Arbitration. (a) Dispute Resolution. Any claim, dispute, difference or controversy between Members arising out of, or relating to, this Agreement, or the subject matter hereof, which cannot be settled by mutual understanding between or among such Members, shall be initially submitted to a panel consisting of an executive management representative of each of the respective Parents of the Members who are party to the claim, dispute, difference or controversy (the "Parties"). The said representatives shall meet and use best efforts to resolve the said claim, dispute, difference or controversy. (b) Arbitration. In the event that the dispute resolution procedure described in Section 9.1(a) does not result in a final resolution of the claim, dispute, difference or controversy within 90 days of the date of submission thereof for resolution, any Party may invoke the following arbitration rights. (1) The claim, dispute, difference or controversy arising out of or in relation to this Agreement or the interpretation or breach thereof shall be referred to arbitration under the rules of the American Arbitration Association ("AAA") to the extent such rules are not inconsistent with these paragraphs. Judgment upon the award of the arbitrators may be entered in any court having jurisdiction thereof or application may be made to such court for a judicial confirmation of the award and an order of enforcement, as the case may be. The demand for arbitration shall be made within a reasonable time after the claim, dispute, difference or controversy or other matter in question, has arisen, - 44 - but not before 90 days after submission thereof for resolution pursuant to Section 9.1(a), and in any event shall not be made after the date when institution of legal or equitable proceedings, based on such claim, dispute, difference or controversy or other matter in question, would be barred by the applicable statute of limitations. (2) The independent arbitration panel shall consist of three independent arbitrators, one of whom shall be appointed by each of the Parties, if there are no more than two such Parties, and by the two Parties having the largest Percentage Interest, if there are more than two Parties, with the third to be chosen by the two arbitrators thus appointed. In the event that either Party entitled to do so does not designate an arbitrator, the other may request a United States federal judge or the Executive Secretary of the AAA to designate an arbitrator for such party; and, if the two arbitrators appointed by the Parties are unable to agree on the appointment of the third arbitrator, either arbitrator may petition the AAA to make the appointment. (3) The place of arbitration shall be Denver, Colorado, or such other place as the parties may agree. 9.2 Jurisdiction; Service of Process. (a) Jurisdiction. Each Member (a) hereby irrevocably submits itself to the non-exclusive jurisdiction of (i) the Supreme Court for the State of New York, sitting in the Borough of Manhattan, and (ii) the United States District Court for the Southern District of New York, for the purposes of any suit, action or other proceeding brought by the other, or its respective successors or assigns, to compel submission to arbitration, in accordance with Section 9.1 hereof, or to enforce a resolution, settlement, order or award made pursuant thereto, or to enforce any obligation for the payment of money contained herein, and (iii) to the extent permitted by applicable law, hereby waives, and agrees not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of the above-named courts, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that the agreement to submit to arbitration, as provided in Section 9.1 hereof, or a resolution, settlement, order or award made pursuant thereto, or such an obligation for the payment of money, may not be enforced in or by such court. Nothing contained herein shall be deemed to waive the right of a Member to seek removal of a matter from state court to federal court if such removal is otherwise permissible. (b) Service of Process. Each Member hereby consents to service of process on it at the office for service of process set forth below as its office for service of process and additionally irrevocably designates and appoints the person named in Schedule 9.2 as its "Agent" and attorney-in-fact to receive service of process in any action, suit or proceeding with respect to any matter as to which it submits to jurisdiction as set forth above, it being agreed that service upon such attorney-in-fact shall constitute valid service upon the Member or its successors or - 45 - assigns. Each Member agrees that (x) the sole responsibilities of the Agent shall be (i) to receive such process, (ii) to send a copy of any such process so received to such Member, by registered airmail, return receipt requested, at the address for it set forth in Section 10.1, or at the last address filled in writing by it with the Agent, and (iii) to give prompt telecopied notice of receipt thereof to it at such address (y) the Agent shall have no responsibility for the receipt or nonreceipt by the respective Member of such process, nor for any performance or nonperformance by the respective Member or its respective successors or assigns, and (z) failure of the Agent to send a copy of any such process or otherwise to give notice thereof to the respective Member shall not affect the validity of such service or any judgment in any action, suit or proceeding based thereon. If service of process cannot be effected in the foregoing manner, each Member further irrevocably consents to the service of process in any action, suit or proceeding by the mailing of copies thereof by registered or certified airmail, postage prepaid, return receipt requested, to it at its address set forth in Section 10.1 hereof. The foregoing, however, shall not limit the right of the Member to serve process in any other manner permitted by law. Any judgment against a Member in any suit for which such Member has no further right of appeal shall be conclusive, and may be enforced in other jurisdictions by suit on the judgment, a certified or true copy of which shall be conclusive evidence of the fact and of the amount of any indebtedness or liability of such Member therein described; provided always that the plaintiff may at its option bring suit, or institute other judicial proceedings, against such Member or any of its assets in the courts of any country or place where such party or such assets may be found. Each Member further covenants and agrees that throughout the term of the Company, it shall maintain a duly appointed agent for the service of summonses and other legal processes in New York. For purposes of this Section 9.2(b), the Agent and offices for service of process for each of the Members shall be as set forth on Schedule 2.1 or such other person or offices as shall be designated in writing by any Member to the other Member.

Every provision of this Agreement is intended to be severable. If any term or provision hereof is illegal, invalid or unenforceable for any reason whatsoever, that term or provision will be enforced to the maximum extent permissible so as to effect the intent of the Members, and such illegality, invalidity or unenforceability shall not affect the validity or legality of the remainder of this Agreement. If necessary to effect the intent of the Members, the Members will negotiate in good faith to amend this Agreement to replace the unenforceable language with enforceable language which as closely as possible reflects such intent. - 47 - 10.7 Confidentiality. (a) Each Member and each of its Controlled Affiliates (each a "Restricted Party") shall, and shall cause its respective officers, directors, employees, attorneys, accountants, consultants and other agents and advisors (collectively, "Agents") to, keep secret and maintain in confidence the terms of this Agreement and all confidential and proprietary information and data of the Company and the other Members or their Affiliates disclosed to it (in each case, a "receiving party") in connection with the formation of the Company and the conduct of the Company's business and in connection with the transactions contemplated by the Contribution Agreement (the "Confidential Information") and shall not disclose Confidential Information, and shall cause its respective Agents not to disclose Confidential Information, to any Person other than the Members, their Controlled Affiliates, their respective Agents that need to know such Confidential Information, or the Company. Each Member further agrees that it shall not use the Confidential Information for any purpose other than monitoring and evaluating its investment, determining and performing its obligations and exercising its rights under this Agreement. The Company and each Member shall take all reasonable measures necessary to prevent any unauthorized disclosure of the Confidential Information by any of their respective Controlled Affiliates or any of their respective Agents. (b) Nothing herein shall prevent the Company, any Restricted Party or its Agents from using, disclosing or authorizing the disclosure of, Confidential Information it receives in the course of the business of the Company which: (i) has been published or is in the public domain through no fault of the receiving party; (ii) prior to receipt hereunder was properly within the legitimate possession of the receiving party or, subsequent to receipt hereunder (or under such Agreement), is lawfully received from a third party having rights therein without restriction of the third party's right to disseminate the Confidential Information and without notice of any restriction against its further disclosure; (iii) is independently developed by the receiving party through parties who have not had, either directly or indirectly, access to or knowledge of such Confidential Information; (iv) is disclosed to a third party with the written approval of the party originally disclosing such information, provided that such Confidential Information shall cease to be confidential and proprietary information covered by this Agreement only to the extent of the disclosure so consented to; (v) subject to the receiving party's compliance with paragraph (d) below, is required to be produced under order of a court of competent jurisdiction or other similar requirements of a governmental agency, provided that such Confidential Information to the extent covered by a protective order or equivalent shall otherwise - 48 - continue to be Confidential Information required to be held confidential for purposes of this Agreement; or (vi) subject to the receiving party's compliance with paragraph (d) below, is necessary or advisable to be disclosed under applicable law or under the rules of a stock exchange or association on which such receiving party's securities (or those of its Affiliate) are listed. (c) Notwithstanding this Section 10.7, any Member may provide Confidential Information (i) to other Persons considering the consummation of a Permitted Transaction with respect to such Member or (ii) to any financial institution in connection with the provision of funds by such financial institution to such Member, so long as prior to any such disclosure such other Person or financial institution executes a confidentiality agreement that provides protection substantially equivalent to the protection provided the Members and the Company in this Section 10.7. (d) In the event that any receiving party (i) determines that it is necessary or advisable to disclose Confidential Information under applicable law (other than under the requirements of a stock exchange or association on which such receiving party's securities or those of its Affiliates are listed) or (ii) becomes legally compelled (by oral questions, interrogatories, requests for information or documents, subpoenas, civil investigative demands or otherwise) to disclose any Confidential Information, the receiving party shall provide the disclosing party with prompt written notice so that in the case of clause (i), the disclosing party can work with the receiving party to limit the disclosure to the extent practicable, or in the case of clause (ii), the disclosing party may seek a protective order or other appropriate remedy or waive compliance with the provisions of this Agreement. In the case of said clause (ii) and in the event that the disclosing party is unable to obtain a protective order or other appropriate remedy, or if the disclosing party so directs, the receiving party shall, and shall cause its employees to, exercise all commercially reasonable efforts to obtain a protective order or other appropriate remedy at the disclosing party's reasonable expense. Failing the entry of a protective order or other appropriate remedy or receipt of a waiver hereunder, the receiving party shall furnish only that portion of the Confidential Information which it is advised by opinion of its counsel is legally required to be furnished and shall exercise all commercially reasonable efforts to obtain reliable assurance that confidential treatment shall be accorded such Confidential Information, it being understood that such reasonable efforts shall be at the cost and expense of the disclosing party whose Confidential Information has been sought. 10.8 Further Action. Each Member, upon the reasonable request of the Managing Member, agrees to perform all further acts and execute, acknowledge, and deliver any documents which may be reasonably necessary, appropriate, or desirable to carry out the intent and purposes of this Agreement. 10.9 Governing Law. - 49 - The validity of this Agreement, the construction of its terms and the interpretation of the rights and duties of the Members hereunder shall be governed by the substantive laws of the State of Delaware without regard to the principles of conflict of laws of the State of Delaware or any other jurisdiction (except those that cannot be waived) that would call for the application of the substantive law of any jurisdiction other than the State of Delaware. 10.10 Waiver of Action for Partition. Each Member irrevocably waives any right that it may have to maintain any action for partition with respect to any of the Property; provided that the foregoing shall not be construed to apply to any action by a Member for the enforcement of its rights under this Agreement. Each Member waives its right to seek a court decree of dissolution (other than a dissolution in accordance with Section 8) or to seek appointment of a court receiver for the Company as now or hereafter permitted under applicable law. 10.11 Counterpart Execution. This Agreement may be executed in any number of counterparts with the same effect as if all the Members had signed the same document. All counterparts shall be construed together and shall constitute one agreement. 10.12 Specific Performance. Each Member agrees with the other Members that the other Members would be irreparably damaged if any of the provisions of this Agreement are not performed in accordance with their specific terms and that monetary damages would not provide an adequate remedy in such event. Accordingly, in addition to any other remedy to which the nonbreaching Members may be entitled, at law or in equity, the nonbreaching Members shall be entitled to injunctive relief to prevent breaches of this Agreement and specifically to enforce the terms and provisions hereof. 10.13 Entire Agreement. The provisions of this Agreement set forth the entire agreement and understanding between the Members pertaining to the subject matter hereof and supersede all prior agreements, oral or written, representations, discussions, negotiations and other communications between the Members pertaining to the subject matter hereof. - 50 - 10.14 Limitation on Rights of Others. Nothing in this Agreement, whether express or implied, shall be construed to give any Person other than the Members and their respective successors and permitted assigns any legal or equitable right, remedy or claim under or in respect of this Agreement. 10.15 Waivers; Remedies. The observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) by the party or parties entitled to enforce such term, but any such waiver shall be effective only if in a writing signed by the party or parties against which such waiver is to be asserted. Except as otherwise provided herein, no failure or delay of any Member in exercising any power or right under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such right or power, preclude any other or further exercise thereof or the exercise of any other right or power. 10.16 Amendment. This Agreement may be amended only in a writing signed by all Members expressly stating that it is an amendment to this Agreement.

otherwise, if the title is one commonly used for officers of a business
corporation formed under the Delaware General Corporation Law, the assignment of
such title shall constitute the delegation to such person of the authorities and
duties that are normally associated with that office. Any delegation pursuant to

incurred by reason of any act or omission performed or omitted by such Member or
Officer in good faith on behalf of the Company and in a manner reasonably
believed to be within the scope of the authority conferred on such Member or
Officer by this Agreement, unless such act or omission constituted bad faith,
gross negligence, fraud or wilful misconduct. To the full extent permitted by
applicable law, an Indemnified Party shall be entitled to indemnification from
the Company for any loss, damage or claim incurred by an Indemnified Party by
reason of any act or omission performed or omitted by an Indemnified Party in
good faith on behalf o the Company and in a manner reasonably believed to be
within the scope of the authority conferred an Indemnified Party by this

fraud or wilful misconduct; provided, however, that any indemnity under this
Section 16 shall be provided out of and to the extent of Company assets only,
and no Member shall have personal liability on account thereof.

                  17.      Assignments. A Member may assign in whole or in part
its limited liability company interest with the written consent of the Member.

Section, the transferee shall be admitted to the Company upon its execution of
an instrument signifying its agreement to be bound by the terms and conditions
of this Agreement. Such admission shall be deemed effective immediately prior to
the transfer, and, immediately following such admission, the transferor Member
shall cease to be a member of the Company.

                  18.      Resignation. A Member may resign from the Company
with the written consent of the Member. If a Member is permitted to resign
pursuant to this Section, an additional member shall be admitted to the Company,
subject to Section19, upon its execution of an instrument signifying its
agreement to be bound by the terms and conditions of this Agreement. Such
admission shall be deemed effective immediately prior to the resignation, and,

                                   ARTICLE VI
                                 INDEMNIFICATION

SECTION 1. LIMITATION ON LIABILITY OF MANAGERS AND OFFICERS. -- No director or
officer of the Company shall have any liability to the Company or the Members
for any losses sustained or liabilities incurred as a result of any act or
omission of such director or officer if (i) the director or officer acted in
good faith and in a manner he or she reasonably believed to be in, or not
opposed to, the interests of the Company and (ii) the conduct of the director or
officer did not constitute actual fraud, gross negligence, or willful
misconduct.

SECTION 2. COMPANY'S OBLIGATION TO INDEMNIFY OFFICERS AND DIRECTORS. -- The
Company shall indemnify and hold harmless the directors and officers of the
Company (individually, an "Indemnitee") from and against any and all losses,
claims, demands, costs, damages, liabilities, expenses of any nature (including
reasonable attorneys' fees and disbursements), judgments, fines, settlements,
and other amounts arising from any and all claims, demands, actions, suits, or
proceedings, civil, criminal, administrative, or investigative, in which an
Indemnitee may be involved, or threatened to be involved, as a party or
otherwise, arising out of or incidental to the business of the Company,
regardless of whether an Indemnitee continues to be a director or officer at the
time any such liability or expense is paid or incurred, if (i) the Indemnitee
acted in good faith and in a manner it or he or she reasonably believed to be
in, or not opposed to, the interests of the Company, and, with respect to any
criminal proceeding, had no reason to believe his or her conduct was unlawful
and (ii) the Indemnitee's conduct did not constitute actual fraud, gross
negligence or willful misconduct.

SECTION 3. COMPANY'S OBLIGATION TO ADVANCE EXPENSES. -- Expenses incurred by an
Indemnitee in defending any claim, demand, action, suit, or proceeding subject
to this Article VI shall, from time to time, be advanced by the Company prior to
the final disposition of such claim, demand, action, suit, or proceeding upon
receipt by the Company of an undertaking by or on behalf of the Indemnitee to
repay such amounts if it is ultimately determined that such person is not
entitled to be indemnified as authorized in this Article VI. The indemnification
provided by this Article VI shall be in addition to any other rights to which an
Indemnitee may be entitled under any agreement, consent of the Members, as a
matter of law or equity, or otherwise, shall continue as to an Indemnitee who
has ceased to serve in such capacity and shall inure to the benefit of the
heirs, successors, assigns and administrators of the Indemnitee. Subject to the
foregoing sentence, the provisions of this Article VI are for the benefit of the
Indemnitees and shall not be deemed to create any rights for the benefit of any
other persons.

                                      -9-

The Issuer any or its Affiliates may act as Transfer Agent, Registrar, co-Registrar, Paying Agent and agent for service of notices and demands in connection with the Notes; provided, however, that neither the Issuer nor any of its Affiliates shall act as Paying Agent for the purposes of Articles Three and Eight and Sections 4.09 and 4.11. 32 The Issuer hereby appoints the office of The Bank of New York in the Borough of Manhattan located at the address set forth in Section 13.02(a) as Registrar and as Transfer Agent and Paying Agent. Subject to any applicable laws and regulations, the Issuer shall cause the Registrar to keep a register (the "Security Register") at its corporate trust office in which, subject to such reasonable regulations it may prescribe, the Issuer shall provide for the registration of ownership, exchange, and transfer of the Notes. Such registration in the Security Register shall be conclusive evidence of the ownership of Notes. Included in the books and records for the Notes shall be notations as to whether such Notes have been paid, exchanged or transferred, canceled, lost, stolen, mutilated or destroyed and whether such Notes have been replaced. In the case of the replacement of any of the Notes, the Registrar shall keep a record of the Note so replaced and the Note issued in replacement thereof. In the case of the cancellation of any of the Notes, the Registrar shall keep a record of the Note so canceled and the date on which such Note was canceled. The Issuer shall enter into an appropriate agency agreement with any Paying Agent or co-Registrar not a party to this Indenture, which, following the effectiveness of a Registration Statement pursuant to the Registration Rights Agreement, shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Issuer shall notify the Trustee of the name and address of any such agent. If the Issuer fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07 of this Indenture. SECTION 2.04. Paying Agent to Hold Money in Trust. Not later than 10:00 am (New York time) on each due date of the principal, premium, if any, and interest on any Notes, the Issuer shall deposit with the Paying Agent money in immediately available funds sufficient to pay such principal, premium, if any, and interest so becoming due on the due date for payment under the Notes. The Issuer shall require each Paying Agent other than the Trustee to agree in writing that such Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal of, premium, if any, and interest on the Notes (whether such money has been paid to it by the Issuer or any other obligor on the Notes), and such Paying Agent shall promptly notify the Trustee of any default by the Issuer (or any other obligor on the Notes) in making any such payment. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee and account for any funds disbursed, and the Trustee may at any time during the continuance of any payment default, upon written request to a Paying Agent, require such Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. Upon doing so, the Paying Agent shall have no further liability for the money so paid over to the Trustee. If the Issuer or any Affiliate of the Issuer acts as Paying Agent, it will, on or before each due date of any principal, premium, if any, or interest on the Notes, segregate and hold in a separate trust fund for the benefit of the Holders a sum of money sufficient to pay such principal, premium, if any, or interest so becoming due until such sum of money shall be paid to such Holders or otherwise disposed of as provided in this Indenture, and will promptly notify the Trustee of its action or failure to act. SECTION 2.05. Holder Lists and Registration Rights Agreements. (a) The Registrar shall preserve in as current a form as is reasonably practicable the most recent list 33 available to it of the names and addresses of Holders and shall otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar, the Issuer shall furnish to the Trustee, in writing no later than the Record Date for each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such Record Date as the Trustee may reasonably require of the names and addresses of Holders, including the aggregate principal amount of Notes held by each Holder. (b) The Trustee shall maintain copies of the Registration Rights Agreement available for inspection by Holders during normal business hours at its Corporate Trust Office for so long as there are Notes outstanding that are subject to registration under the Registration Rights Agreement. SECTION 2.06. Transfer and Exchange. (a) Where Notes are presented to the Registrar or a co-Registrar with a request to register a transfer or to exchange them for an equal principal amount of Notes of other denominations, the Registrar shall register the transfer or make the exchange in accordance with the requirements of this Section 2.06. To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes, of any authorized denominations and of a like aggregate principal amount, at the Registrar's request. No service charge shall be made for any registration of transfer or exchange of Notes (except as otherwise expressly permitted herein), but the Issuer may require payment of a sum sufficient to cover any agency fee or similar charge payable in connection with any such registration of transfer or exchange of Notes (other than any agency fee or similar charge payable upon exchanges pursuant to Sections 2.10, 3.08 or 9.05) or in accordance with an Excess Proceeds Offer pursuant to Section 4.09 or Change of Control Offer pursuant to Section 4.11, not involving a transfer. Upon presentation for exchange or transfer of any Note as permitted by the terms of this Indenture and by any legend appearing on such Note, such Note shall be exchanged or transferred upon the Security Register and one or more new Notes shall be authenticated and issued in the name of the Holder (in the case of exchanges only) or the transferee, as the case may be. No exchange or transfer of a Note shall be effective under this Indenture unless and until such Note has been registered in the name of such Person in the Security Register. Furthermore, the exchange or transfer of any Note shall not be effective under this Indenture unless the request for such exchange or transfer is made by the Holder or by a duly authorized attorney-in-fact at the office of the Registrar. Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Issuer or the Registrar) be duly endorsed, or be accompanied by a written instrument or transfer, in form satisfactory to the Issuer and the Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Issuer evidencing the same indebtedness, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange. 34 In the event that the Issuer delivers to the Trustee a copy of an Officers' Certificate certifying that a registration statement under the Securities Act with respect to the Exchange Offer, or a Shelf Registration Statement, as the case may be, has been declared effective by the SEC, and that the Issuer has offered Exchange Notes to the Holders in accordance with the Exchange Offer or that Notes have been offered pursuant to such Shelf Registration Statement, the Trustee shall exchange or issue upon transfer, as the case may be, upon request of any Holder, such Holder's Notes for (i) in the case of an Exchange Offer, Exchange Notes upon the terms set forth in the Exchange Offer or (ii) in the case of a transfer pursuant to a Shelf Registration Statement, Notes that comply with the requirements applicable following such a transfer as set forth in Section 2.01(c). The Issuer shall not be required (i) to issue, register the transfer of, or exchange any Note during a period beginning at the opening of 15 Business Days before the day of the mailing of a notice of redemption of Notes selected for redemption under Section 3.02 and ending at the close of business on the day of such mailing, or (ii) to register the transfer of or exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. (b) Notwithstanding any provision to the contrary herein, so long as a Global Note remains outstanding and is held by or on behalf of the Depositary, transfers of a Global Note, in whole or in part, or of any beneficial interest therein, shall only be made in accordance with Section 2.01(d), Section 2.06(a) and this Section 2.06(b); provided, however, that a beneficial interest in a Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Global Note in accordance with the transfer restrictions set forth in the restricted Note legend on the Note, if any. (i) Except for transfers or exchanges made in accordance with any of clauses (ii), (iii), (iv) or (v) of this Section 2.06(b), transfers of a Global Note shall be limited to transfers of such Global Note in whole, but not in part, to nominees of the Depositary or to a successor of the Depositary or such successor's nominee. (ii) Restricted Global Note to Regulation S Global Note. If the Holder of a beneficial interest in the Restricted Global Note at any time wishes to exchange its interest in such Restricted Global Note for an interest in the Regulation S Global Note, or to transfer its interest in such Restricted Global Note to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Regulation S Global Note, such transfer or exchange may be effected, only in accordance with this clause (ii) and the rules and procedures of the Depositary. Upon receipt by the Registrar from the Transfer Agent of (A) instructions directing the Registrar to credit or cause to be credited an interest in the Regulation S Global Note in a specified principal amount and to cause to be debited an interest in the Restricted Global Note in such specified principal amount, and (B) a certificate in the form of Exhibit B attached hereto given by the Holder of such beneficial interest stating that the transfer of such interest has been made in compliance with the transfer restrictions applicable to the Global Notes and (x) pursuant to and in accordance with Regulation S or (y) that the Note being transferred is being transferred in a transaction permitted by Rule 144, then the Registrar shall instruct the Depositary to reduce or cause to be reduced the principal amount of the Restricted Global Note and to 35 increase or cause to be increased the principal amount of the Regulation S Global Note by the aggregate principal amount of the interest in the Restricted Global Note to be exchanged. (iii) Regulation S Global Note to Restricted Global Note. If the Holder of a beneficial interest in the Regulation S Global Note at any time wishes to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Restricted Global Note, such transfer may be effected only in accordance with this clause (iii) and the rules and procedures of the Depositary. Upon receipt by the Registrar from the Transfer Agent of (A) instructions directing the Registrar to credit or cause to be credited an interest in the Restricted Global Note in a specified principal amount and to cause to be debited an interest in the Regulation S Global Note in such specified principal amount, and (B) a certificate in the form of Exhibit C attached hereto given by the Holder of such beneficial interest stating that the transfer of such interest has been made in compliance with the transfer restrictions applicable to the Global Notes and stating that (x) the Person transferring such Interest reasonably believes that the Person acquiring such interest is a QIB and is obtaining such interest in a transaction meeting the requirements of Rule 144A and any applicable securities laws of any state of the United States or (y) that the Person transferring such interest is relying on an exemption other than Rule 144A from the registration requirements of the Securities Act and, in such circumstances, such Opinion of Counsel as the Issuer or the Trustee may reasonably request to ensure that the requested transfer or exchange is being made pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act, then the Registrar shall instruct the Depositary to reduce or cause to be reduced the principal amount of the Regulation S Global Note and to increase or cause to be increased the principal amount of the Restricted Global Note by the aggregate principal amount of the interest in the Regulation S Global Note to be exchanged or transferred. (iv) Restricted Global Note to Exchange Global Note. Following the earlier of the consummation of the Exchange Offer or the transfer of a Note pursuant to a Shelf Registration Statement that results in beneficial interests in such Note being reflected in the Exchange Global Note, if the Holder of a beneficial interest in the Restricted Global Note at any time wishes to exchange its interest in such Restricted Global Note for an interest in the Exchange Global Note, or to transfer its interest in such Restricted Global Note to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Regulation S Global Note, such transfer or exchange, if not effected pursuant to Section 2.06(a) may be effected only in accordance with this clause (iv) and the rules and procedures of the Depositary. Upon receipt by the Registrar from the Transfer Agent of (A) instructions directing the Registrar to credit or cause to be credited an interest in the Exchange Global Note in a specified principal amount and to cause to be debited an interest in the Restricted Global Note in such specified principal amount, and (B) a certificate in the form of Exhibit B attached hereto given by the Holder of such beneficial interest stating that the transfer of such interest has been made in compliance with the transfer restrictions applicable to the Global Notes and (x) pursuant to and in accordance with Regulation S or (y) that the Note being transferred is being transferred in a transaction permitted by Rule 144, then the Registrar shall instruct the Depositary to 36 reduce or cause to be reduced the principal amount of the Restricted Global Note and to increase or cause to be increased the principal amount of the Regulation S Global Note by the aggregate principal amount of the interest in the Restricted Global Note to be exchanged or transferred. (v) Regulation S Global Note to Exchange Global Note. Following the earlier of the consummation of the Exchange Offer or the transfer of a Note pursuant to a Shelf Registration Statement that results in beneficial interests in such Note being reflected in the Exchange Global Note, if the Holder of a beneficial interest in the Regulation S Global Note at any time wishes to exchange its interest in such Regulation S Global Note for an interest in the Exchange Global Note, or to transfer its interest in such Regulation S Global Note to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Exchange Global Note, such transfer or exchange, if not effected pursuant to an Exchange Offer or a Shelf Registration Statement in accordance with Section 2.06(a) may be effected only in accordance with this clause (v) and the rules and procedures of the Depositary. Upon receipt by the Registrar from the Transfer Agent of instructions directing the Registrar to credit or cause to be credited an interest in the Exchange Global Note in a specified principal amount and to cause to be debited an interest in the Regulation S Global Note in such specified principal amount, then the Registrar shall instruct the Depositary to reduce or cause to be reduced the principal amount of the Regulation S Global Note and to increase or cause to be increased the principal amount of the Exchange Global Note by the aggregate principal amount of the interest in the Regulation S Global Note to be exchanged or transferred. (vi) Global Notes to Certificated Notes. In the event that a Global Note is exchanged for Notes in certificated, registered form pursuant to Section 2.10, the effectiveness of a Shelf Registration Statement with respect to such Notes, such Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of clauses (ii) and (iii) above (including the certification requirements intended to ensure that such transfers comply with Rule 144A or Regulation S under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Issuer and the Trustee. (c) Except in connection with an Exchange Offer or a Shelf Registration Statement contemplated by and in accordance with the terms of the Registration Rights Agreement, if Notes are issued upon the transfer, exchange or replacement of Notes bearing the restricted Notes legends set forth in Exhibit A hereto, the Notes so issued shall bear the restricted Notes legends, and a request to remove such restricted Notes legends from Notes will not be honored unless there is delivered to the Issuer such satisfactory evidence, which may include an Opinion of Counsel licensed to practice law in the State of New York, as may be reasonably required by the Issuer, that neither the legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A or Rule 144(k) under the Securities Act. Upon provision of such satisfactory evidence, the Trustee, at the direction of the Issuer, shall authenticate and deliver Notes that do not bear the legend. (d) The Trustee shall have no responsibility for any actions taken or not taken by the Depositary, for any Depositary records or beneficial ownership interests or for any transactions 37 between the Depositary and any Agent Member or between or among the Depositary, a participant and/or any holder or owner of a beneficial interest in a Global Note. (e) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Notes (including any transfers between or among the Depositary's participants or beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation, including delivery of Opinions of Counsel, as is expressly required by, and to do so if and when expressly required by, the terms of this Indenture and to examine the same to determine substantial compliance as to form with the express requirements hereof. SECTION 2.07. Replacement Notes. If a mutilated certificated Note is surrendered to the Registrar or if the Holder claims that the Note has been lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall authenticate a replacement Note in such form as the Note mutilated, lost, destroyed or wrongfully taken if the Holder satisfies any other reasonable requirements of the Trustee or the Issuer. If required by the Trustee or the Issuer, such Holder shall furnish an indemnity or indemnity bond sufficient in the judgment of the Issuer and the Trustee to protect the Issuer, the Trustee, the Paying Agent, the Transfer Agent, the Registrar and any co-Registrar, and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer and the Trustee may charge the Holder for their expenses in replacing a Note. Every replacement Note shall be an additional obligation of the Issuer. SECTION 2.08. Outstanding Notes. Notes outstanding at any time are all Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding. A Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note. If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee and the Issuer receive proof satisfactory to them that the Note which has been replaced is held by a bona fide purchaser. If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a Redemption Date or maturity date money sufficient to pay all principal, premium, if any, interest payable on that date with respect to the Notes (or portions thereof) to be redeemed or maturing, as the case may be, and the Paying Agent is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture, then on and after that date such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue. SECTION 2.09. Notes Held by Issuer. In determining whether the Holders of the required principal amount of Notes have concurred in any direction or consent or any amendment, modification or other change to this Indenture, Notes owned by the Issuer or by an Affiliate of the Issuer shall be disregarded and treated as if they were not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent or any amendment, modification or other change to this Indenture, 38 only Notes which a Trust Officer of the Trustee actually knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee's right so to act with respect to the Notes and that the pledgee is not the Issuer or an Affiliate of the Issuer. SECTION 2.10. Certificated Notes. (a) A Global Note deposited with the Depositary or other custodian for the Depositary pursuant to Section 2.01 shall be transferred to the beneficial owners thereof in the form of certificated Notes only if such transfer complies with Section 2.06 and (i) the Depositary notifies the Issuer that it is unwilling or unable to continue as the Depositary for such Global Note, or if at any time the Depositary ceases to be a "clearing agency" registered under the Exchange Act and a successor depositary is not appointed by the Issuer within 90 days of such notice, or (ii) the Issuer, at its option, executes and delivers to the Trustee a notice that such Global Note be so transferable, registrable and exchangeable, or (iii) an Event of Default, or an event which after notice or lapse of time or both would be an Event of Default, has occurred and is continuing with respect to the Notes or (iv) the issuance of such certificated Notes is necessary in order for a Holder or beneficial owner to present its Note or Notes to a Paying Agent in order to avoid any tax that is imposed on or with respect to a payment made to such Holder or beneficial owner. Notice of any such transfer shall be given by the Issuer in accordance with the provisions of Section 12.02(a). (b) Any Global Note that is transferable to the beneficial owners thereof in the form of certificated Notes pursuant to this Section 2.10 shall be surrendered by the Depositary to the Transfer Agent, to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion of such Global Note, an equal aggregate principal amount at maturity of Notes of authorized denominations in the form of certificated Notes. Any portion of a Global Note transferred or exchanged pursuant to this Section 2.10 shall be executed, authenticated and delivered only in registered form in denominations of $1,000 and any integral multiple thereof and registered in such names as the Depositary shall direct. Subject to the foregoing, a Global Note is not exchangeable except for a Global Note of like denomination to be registered in the name of the Depositary or its nominee. In the event that a Global Note becomes exchangeable for certificated Notes, payment of principal, premium, if any, and interest on the certificated Notes will be payable, and the transfer of the certificated Notes will be registrable, at the office or agency of the Issuer maintained for such purposes in accordance with Section 2.03. Such certificated Notes shall bear the applicable legends set forth in Exhibit A hereto. (c) In the event of the occurrence of any of the events specified in Section 2.10(a), the Issuer will promptly make available to the Trustee a reasonable supply of certificated Notes in definitive, fully registered form without interest coupons. SECTION 2.11. Cancellation. The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee, in accordance with its customary procedures, and no one else shall cancel (subject to the record retention requirements of the Exchange Act and the Trustee's retention policy) all Notes surrendered for registration of transfer, exchange, payment or cancellation and dispose of such cancelled Notes in its customary manner. Except as otherwise provided in this Indenture the 39 Issuer may not issue new Notes to replace Notes it has redeemed, paid or delivered to the Trustee for cancellation. SECTION 2.12. Defaulted Interest. Any interest on any Note that is payable, but is not punctually paid or duly provided for, on the dates and in the manner provided in the Notes and this Indenture (all such interest herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder on the relevant Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Issuer, at its election in each case, as provided in clause (a) or (b) below: (a) The Issuer may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes are registered at the close of business on a special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Issuer shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Issuer may deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest; or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. In addition, the Issuer shall fix a special Record Date for the payment of such Defaulted Interest, such date to be not more than 15 days and not less than 10 days prior to the proposed payment date and not less than 15 days after the receipt by the Trustee of the notice of the proposed payment date. The Issuer shall promptly but, in any event, not less than 15 days prior to the special Record Date, notify the Trustee of such special Record Date and, in the name and at the expense of the Issuer, the Trustee shall cause notice of the proposed payment date of such Defaulted Interest and the special Record Date therefor to be mailed first-class, postage prepaid to each Holder as such Holder's address appears in the Security Register, not less than 10 days prior to such special Record Date. Notice of the proposed payment date of such Defaulted Interest and the special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Notes are registered at the close of business on such special Record Date and shall no longer be payable pursuant to clause (b) below. (b) The Issuer may make payment of any Defaulted Interest on the Notes in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Issuer to the Trustee of the proposed payment date pursuant to this clause, such manner of payment shall be deemed reasonably practicable. Subject to the foregoing provisions of this Section 2.12, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note. SECTION 2.13. Computation of Interest. Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. 40 SECTION 2.14. CUSIP, ISIN and Common Code Numbers. The Issuer in issuing the Notes may use CUSIP, ISIN and Common Code numbers (if then generally in use), and, if so, the Trustee shall use CUSIP, ISIN and Common Code numbers, as appropriate, in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers or codes either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuer will promptly notify the Trustee of any change in the CUSIP, ISIN or Common Code numbers. SECTION 2.15. Issuance of Additional Notes and Exchange Notes. The Issuer may, subject to Section 4.06 of this Indenture, issue Additional Notes under this Indenture in accordance with the procedures of Section 2.02. The Original Notes issued on the date of this Indenture and any Additional Notes subsequently issued shall be treated as a single class for all purposes under this Indenture. ARTICLE THREE REDEMPTION; OFFERS TO PURCHASE SECTION 3.01. Optional Redemption. Except as set forth in the next paragraph, the Notes will not be redeemable at the option of the Issuer prior to July 1, 2008. Starting on that date, the Issuer may redeem all or any portion of the Notes, at once or over time, after giving the required notice under this Indenture. The Notes may be redeemed at the redemption prices set forth below, plus accrued and unpaid interest to the redemption date (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant interest payment date). The following prices are for Notes redeemed during the 12-month period commencing on July 1, 2008 of the years set forth below, and are expressed as percentages of principal amount:
REDEMPTION ---------- YEAR PRICE ---- ----- 2008..................................................................................... 103.375% 2009..................................................................................... 102.250% 2010..................................................................................... 101.125% 2011 and thereafter...................................................................... 100.000%
In addition, at any time and from time to time, prior to July 1, 2006, the Issuer may redeem up to a maximum of 35% of the original aggregate principal amount of the Notes (calculated giving effect to any issuance of Additional Notes) with the proceeds of one or more Public Equity Offerings, at a redemption price equal to 106.750% of the principal amount thereof, plus accrued and unpaid interest to the redemption date (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant interest payment date); provided, however, that after giving effect to any such redemption, at least 65% of the original aggregate principal amount of the Notes (calculated giving effect to any issuance of Additional Notes) remains outstanding (excluding Notes held by Arch Coal or any of its Subsidiaries). Any such redemption shall be made within 75 days of such Public Equity Offering upon not less than 30 nor more than 60 days' prior notice. 41 Any redemption pursuant to this Section 3.01 shall be made pursuant to the provisions of this Article Three. SECTION 3.02. Notices to Trustee. If the Issuer elects to redeem Notes pursuant to Section 3.01, it shall notify the Trustee in writing of the Redemption Date, the principal amount of Notes to be redeemed and the paragraph of the Notes pursuant to which the redemption will occur. The Issuer shall give each notice to the Trustee provided for in this Section 3.02 in writing at least 45 days before the date notice is mailed to the Holders pursuant to Section 3.04 unless the Trustee consents to a shorter period. Such notice shall be accompanied by an Officers' Certificate from the Issuer to the effect that such redemption will comply with the conditions herein. If fewer than all the Notes are to be redeemed, the Record Date relating to such redemption shall be selected by the Issuer and given to the Trustee, which Record Date shall be not less than 15 days after the date of notice to the Trustee. Except as otherwise provided herein, no notice or communication to the Trustee shall be deemed effectively given unless it is actually received by a Trust Officer at its Corporate Trust Office. SECTION 3.03. Selection of Notes to be Redeemed. If less than all of the Notes are to be redeemed, the Trustee shall select the Notes to be redeemed in compliance with the requirements, as certified to it by the Issuer, of the principal national securities exchange or automated quotation system, if any, on which the Notes are listed or, if the Notes are not listed on a national securities exchange or automated quotation system, by lot or by such other method as the Trustee in its sole discretion shall deem fair and appropriate; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Note not redeemed to less than $1,000. The Trustee shall make the selection from the Notes outstanding and not previously called for redemption. The Trustee may select for redemption portions equal to $1,000 in principal amount or any integral multiple thereof. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. The Trustee shall notify the Issuer and the Registrar promptly in writing of the Notes or portions of Notes to be called for redemption. SECTION 3.04. Notice of Redemption. (a) At least 30 days but not more than 60 days before a date for redemption of Notes, the Issuer shall mail a notice of redemption by first-class mail to each Holder to be redeemed and shall comply with the provisions of Section 13.02(b). (b) The notice shall identify the Notes to be redeemed (including CUSIP, ISIN and Common Code numbers) and shall state: (i) the Redemption Date; (ii) the Redemption Price and the amount of accrued interest, if any to be paid; 42 (iii) the name and address of the Paying Agent; (iv) that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price plus accrued interest, if any; (v) that, if any Note is being redeemed in part, the portion of the principal amount (equal to $1,000 in principal amount or any integral multiple thereof) of such Note to be redeemed and that, on and after the Redemption Date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion thereof will be reissued; (vi) that, if any Note contains a CUSIP, ISIN or Common Code number, no representation is being made as to the correctness of such CUSIP, ISIN or Common Code number either as printed on the Notes or as contained in the notice of redemption and that reliance may be placed only on the other identification numbers printed on the Notes; (vii) that, unless the Issuer defaults in making such redemption payment, interest on the Notes (or portion thereof) called for redemption shall cease to accrue on and after the Redemption Date; and (viii) the paragraph of the Notes pursuant to which the Notes called for redemption are being redeemed. At the Issuer's written request, the Trustee shall give a notice of redemption in the Issuer's name and at the Issuer's expense. In such event, the Issuer shall provide the Trustee with the notice and the other information required by this Section 3.04. SECTION 3.05. Effect of Notice of Redemption. Once a notice of redemption is mailed, Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price stated in the notice. Upon surrender of any Notes to the Paying Agent, such Notes shall be paid at the Redemption Price stated in the notice, plus accrued interest, if any, to the Redemption Date. In any event, failure to give such notice, or any defect therein, shall not effect the validity of the proceedings for the redemption of Notes held by Holders to whom such notice was properly given. Notice of redemption shall be deemed to be given when mailed, whether or not the Holder receives the notice. In any event, failure to give such notice, or any defect therein, shall not affect the validity of the proceedings for the redemption of Notes held by Holders to whom such notice was properly given. SECTION 3.06. Deposit of Redemption Price. On or prior to any Redemption Date, the Issuer shall deposit or cause to be deposited with the Paying Agent a sum in same day funds sufficient to pay the Redemption Price of and accrued interest on all Notes to be redeemed on that date other than Notes or portions of Notes called for redemption that have previously been delivered by the Issuer to the Trustee for cancellation. The Paying Agent shall return to the Issuer any money so deposited that is not required for that purpose. 43 SECTION 3.07. Payment of Notes Called for Redemption. If notice of redemption has been given in the manner provided above, the Notes or portion of Notes specified in such notice to be redeemed shall become due and payable on the Redemption Date at the Redemption Price stated therein, together with accrued interest to such Redemption Date, and on and after such date (unless the Issuer shall default in the payment of such Notes at the Redemption Price and accrued interest to the Redemption Date, in which case the principal, until paid, shall bear interest from the Redemption Date at the rate prescribed in the Notes), such Notes shall cease to accrue interest. Upon surrender of any Note for redemption in accordance with a notice of redemption, such Note shall be paid and redeemed by the Issuer at the Redemption Price, together with accrued interest, if any, to the Redemption Date; provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders registered as such at the close of business on the relevant Record Date. SECTION 3.08. Notes Redeemed in Part. (a) Upon surrender of a Global Note that is redeemed in part, the Paying Agent shall forward such Global Note to the Trustee who shall make a notation on the Security Register to reduce the principal amount of such Global Note to an amount equal to the unredeemed portion of the Global Note surrendered; provided, however, that each such Global Note shall be in a principal amount at final Stated Maturity of $1,000 or an integral multiple thereof. (b) Upon surrender and cancellation of a certificated Note that is redeemed in part, the Issuer shall execute and the Trustee shall authenticate for the Holder (at the Issuer's expense) a new Note equal in principal amount to the unredeemed portion of the Note surrendered and canceled; provided, however, that each such certificated Note shall be in a principal amount at final Stated Maturity of $1,000 or an integral multiple thereof. ARTICLE FOUR COVENANTS SECTION 4.01. Payment of Notes. Each of the Issuer and the Guarantors covenants and agrees for the benefit of the Holders that it shall duly and punctually pay the principal of, premium, if any, and interest on the Notes on the dates and in the manner provided in the Notes and in this Indenture. Principal, premium, if any, and interest shall be considered paid on the date due if on such date the Trustee or the Paying Agent (other than the Issuer or any of its Affiliates) holds, in accordance with this Indenture, money sufficient to pay all principal, premium, if any, and interest then due. If the Issuer or any of its Affiliates acts as Paying Agent, principal, premium, if any, and interest shall be considered paid on the due date if the entity acting as Paying Agent complies with Section 2.04. Each of the Issuer or the Guarantors shall pay interest on overdue principal at the rate specified therefor in the Notes. The Issuer or the Guarantors shall pay interest on overdue installments of interest at the same rate to the extent lawful. SECTION 4.02. Corporate Existence. Subject to Article Five, the Issuer and each Restricted Subsidiary shall do or cause to be done all things necessary to preserve and keep in full force and effect their corporate, partnership, limited liability company or other 44 existence and the rights (charter and statutory), licenses and franchises of Arch Western and each Restricted Subsidiary; provided, however, that Arch Western shall not be required to preserve any such right, licence or franchise if the Board of Directors of Arch Western shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Issuer and the Restricted Subsidiaries as a whole and that the loss thereof is not disadvantageous in any material respect to the Holders. SECTION 4.03. Maintenance of Properties. Arch Western shall cause all properties owned by it or any of its Subsidiaries or used or held for use in the conduct of its business or the business of Arch Western or any of its Subsidiaries to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and shall cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as, in the judgment of Arch Western, may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section 4.03 shall prevent Arch Western from discontinuing the maintenance of any such properties if such discontinuance is, in the judgment of Arch Western, desirable in the conduct of the business of Arch Western and its Subsidiaries as a whole and not disadvantageous in any material respect to the Holders. SECTION 4.04. Insurance. Arch Western shall maintain, and shall cause its Subsidiaries to maintain, insurance with carriers believed by Arch Western to be responsible, against such risks and in such amounts, and with such deductibles, retentions, self-insured amounts and coinsurance provisions, as Arch Western believes are customarily carried by businesses similarly situated and owning like properties, including as appropriate general liability, property and casualty loss and interruption of business insurance. SECTION 4.05. Statement as to Compliance. (a) The Issuer shall deliver to the Trustee, within 90 days after the end of each fiscal year, an Officers' Certificate stating that in the course of the performance by the signer of its duties as an officer of the Issuer he would normally have knowledge of any Default and whether or not the signer knows of any Default that occurred during such period and if any specifying such Default, its status and what action the Issuer is taking or proposed to take with respect thereto. For purposes of this Section 4.05(a), such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture. The Issuer shall comply with TIA Section 314(a)(4) The Issuer's delivery to the Trustee of the reports, information and documents required by said Section 314(a)(4) is for informational purposes only and the Trustee's receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer's compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers' Certificates).. (b) When any Default has occurred and is continuing under this Indenture, or if the trustee of, or the holder of, any other evidence of Debt of Arch Western or any Subsidiary outstanding in a principal amount of $25,000,000 or more gives any notice stating that it is a Notice of Default or takes any other action to accelerate such Debt or enforce any Note therefor, the Issuer shall deliver to the Trustee within five Business Days by registered or certified mail or 45 facsimile transmission an Officers' Certificate specifying such event, notice or other action, its status and what action the Issuer is taking or proposes to take with respect thereto. SECTION 4.06. Limitation on Debt. The Issuer shall not Incur any Debt other than the Notes and any Additional Notes. Arch Western shall not, and shall not permit any Restricted Subsidiary to, Incur, directly or indirectly, any Debt unless, after giving effect to the application of the proceeds thereof, no Default or Event of Default would occur as a consequence of such Incurrence or be continuing following such Incurrence and either: (1) such Debt is Debt of Arch Western or a Subsidiary Guarantor and, after giving effect to the Incurrence of such Debt and the application of the proceeds thereof, Consolidated Interest Coverage Ratio of Arch Western would be at least 2.0 to 1.0, or (2) such Debt is Permitted Debt. The term "Permitted Debt" is defined to include the following: (a) Debt of the Issuer evidenced by the Notes (not including any Additional Notes) issued in this offering and the Exchange Notes issued in exchange for such Notes and the Note Guarantees thereof; (b) Debt of Arch Western or a Restricted Subsidiary in respect of Capital Lease Obligations and Purchase Money Debt; provided that: (i) the aggregate principal amount of such Debt does not exceed the Fair Market Value (on the date of the Incurrence thereof) of the Property acquired, constructed or leased, and (ii) the aggregate principal amount of all Debt Incurred and then outstanding pursuant to this clause (b) (together with all Permitted Refinancing Debt Incurred and then outstanding in respect of Debt previously Incurred pursuant to this clause (b)) does not exceed, at any one time outstanding, 5% of Consolidated Net Tangible Assets; (c) Debt of Arch Western owing to and held by any Restricted Subsidiary and Debt of a Restricted Subsidiary owing to and held by Arch Western or any Restricted Subsidiary; provided, however, that (1) any subsequent issue or transfer of Capital Stock or other event that results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any subsequent transfer of any such Debt (except to Arch Western or a Restricted Subsidiary) shall be deemed, in each case, to constitute the Incurrence of such Debt by the issuer thereof and (2) if a Guarantor is the obligor on such Debt, such Debt is subordinated in right of payment to the Note Guarantee of such Guarantor; (d) Debt under Interest Rate Agreements entered into by Arch Western or a Restricted Subsidiary for the purpose of managing interest rate risk in the ordinary course of the financial management of Arch Western or such Restricted Subsidiary and not for speculative purposes, provided that the obligations under such agreements are directly related to payment obligations on Debt otherwise permitted by the terms of this covenant; 46 (e) Debt under Currency Exchange Protection Agreements entered into by Arch Western or a Restricted Subsidiary for the purpose of managing currency exchange rate risks directly related to transactions entered into by Arch Western or such Restricted Subsidiary in the ordinary course of business and not for speculative purposes; (f) Debt under Commodity Price Protection Agreements entered into by Arch Western or a Restricted Subsidiary in the ordinary course of the financial management of Arch Western or such Restricted Subsidiary and not for speculative purposes; (g) Debt in connection with one or more standby letters of credit or performance or surety bonds or completion guarantees issued by Arch Western or a Restricted Subsidiary in the ordinary course of business or pursuant to self-insurance obligations and not in connection with the borrowing of money or the obtaining of advances or credit; (h) Debt of Arch Western or a Restricted Subsidiary outstanding on the Issue Date not otherwise described in clauses (a) through (g) above; (i) other Debt of Arch Western or any Subsidiary Guarantor in an aggregate principal amount outstanding at any one time not to exceed $100,000,000; (j) Permitted Refinancing Debt Incurred in respect of Debt Incurred pursuant to clause (1) of the first paragraph of this Section 4.06 and clauses (b) and (h) above; and (k) Debt consisting of installment payment obligations to the federal government in connection with the acquisition of coal leases in the ordinary course of business and consistent with past practices. Notwithstanding anything to the contrary contained in this Section 4.06; (i) Arch Western shall not permit any Restricted Subsidiary that is not a Guarantor to Incur any Debt pursuant to this Section 4.06 if the proceeds thereof are used, directly or indirectly, to Refinance any Debt of any Guarantor; and (ii) accrual of interest, accretion or amortization of original issue discount and the payment of interest or dividends in the form of additional Debt, will be deemed not to be an Incurrence of Debt for purposes of this covenant. For purposes of determining compliance with this Section 4.06 in the event that an item of Debt meets the criteria of more than one of the categories of Permitted Debt described in clauses (a) through (j) above or is entitled to be incurred pursuant to clause (1) of the first paragraph of this Section 4.06, Arch Western shall, in its sole discretion, classify such item of Debt in any manner that complies with this Section 4.06. SECTION 4.07. Limitation on Liens. Arch Western shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, Incur or suffer to exist, any Lien on the Arch Coal Notes, except for the Liens securing the Notes and Additional Notes and Liens described in clause (k) of the definition of Permitted Liens. 47 Arch Western shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, Incur or suffer to exist, any Lien (other than Permitted Liens) upon any of its Property (including Capital Stock of a Restricted Subsidiary), whether owned at the Issue Date or thereafter acquired, or any interest therein or any income or profits therefrom, unless it has made or will make effective provision whereby the Notes or any Note Guarantee will be secured by such Lien equally and ratably with (or, if such other Debt constitutes Subordinated Obligations, prior to) all other Debt of Arch Western or any Restricted Subsidiary secured by such Lien for so long as such other Debt is secured by such Lien. SECTION 4.08. Limitation on Restricted Payments. Arch Western shall not make, and shall not permit any Restricted Subsidiary to make, directly or indirectly, any Restricted Payment if at the time of, and after giving effect to, such proposed Restricted Payment, (a) a Default or Event of Default shall have occurred and be continuing, (b) Arch Western could not Incur at least $1.00 of additional Debt pursuant to clause (1) of the first paragraph of Section 4.06 of this Indenture, (c) the aggregate amount of such Restricted Payment and all other Restricted Payments declared or made since the Issue Date (the amount of any Restricted Payment, if made other than in cash, to be based upon Fair Market Value at the time of such Restricted Payment) would exceed an amount equal to the sum of: (i) 50% of the aggregate amount of Consolidated Net Income of Arch Western accrued during the period (treated as one accounting period) from the beginning of the fiscal quarter during which the Issue Date occurs to the end of the most recent fiscal quarter ending at least 45 days prior to the date of such Restricted Payment (or if the aggregate amount of Consolidated Net Income of Arch Western for such period shall be a deficit, minus 100% of such deficit), plus (ii) 100% of the Capital Stock Sale Proceeds, plus (iii) the sum of: (1) the aggregate net cash proceeds received by Arch Western or any Restricted Subsidiary from the issuance or sale after the Issue Date of convertible or exchangeable Debt that has been converted into or exchanged for Capital Stock (other than Disqualified Stock) of Arch Western, and (2) the aggregate amount by which Debt (other than Subordinated Obligations) of Arch Western or any Restricted Subsidiary is reduced on Arch Western's consolidated balance sheet on or after the Issue Date upon the conversion or exchange of any Debt issued or sold on or prior to the Issue Date that is convertible or exchangeable for Capital Stock (other than Disqualified Stock) of Arch Western, excluding, in the case of clause (1) or (2): 48 (x) any such Debt issued or sold to Arch Western or a Subsidiary of Arch Western or an employee stock ownership plan or trust established by Arch Coal or any such Subsidiary for the benefit of their employees, and (y) the aggregate amount of any cash or other Property distributed by Arch Western or any Restricted Subsidiary upon any such conversion or exchange; plus (iv) an amount equal to the sum of: (B) the net reduction in Investments in any Person other than Arch Western or a Restricted Subsidiary resulting from dividends, repayments of loans or advances or other transfers of Property, in each case to Arch Western or any Restricted Subsidiary from such Person, and (C) the portion (proportionate to Arch Western's equity interest in such Unrestricted Subsidiary) of the Fair Market Value of the net assets of an Unrestricted Subsidiary of Arch Western at the time such Unrestricted Subsidiary is designated a Restricted Subsidiary; provided, however, that the foregoing sum shall not exceed, in the case of any Person, the amount of Investments previously made (and treated as a Restricted Payment) by Arch Western or any Restricted Subsidiary in such Person. Notwithstanding the foregoing limitation, Arch Western may: (a) pay dividends on its Capital Stock within 60 days of the declaration thereof if, on the declaration date, such dividends could have been paid in compliance with this Indenture; provided, however, that such dividend shall be included in the calculation of the amount of Restricted Payments; (b) purchase, repurchase, redeem, legally defease, acquire or retire for value Capital Stock of Arch Western or Subordinated Obligations in exchange for, or out of the proceeds of the substantially concurrent sale of, Capital Stock of Arch Western (other than Disqualified Stock and other than Capital Stock issued or sold to a Subsidiary of Arch Coal or an employee stock ownership plan or trust established by Arch Coal or any such Subsidiary for the benefit of their employees); provided, however, that (i) such purchase, repurchase, redemption, legal defeasance, acquisition or retirement shall be excluded in the calculation of the amount of Restricted Payments and (ii) the Capital Stock Sale Proceeds from such exchange or sale shall be excluded from the calculation pursuant to clause (c)(ii) above; 49 (c) purchase, repurchase, redeem, legally defease, acquire or retire for value any Subordinated Obligations in exchange for, or out of the proceeds of the substantially concurrent sale of, Permitted Refinancing Debt; provided, however, that such purchase, repurchase, redemption, legal defeasance, acquisition or retirement shall be excluded in the calculation of the amount of Restricted Payments; (d) repurchase shares of, or options to purchase shares of, common stock of Arch Western or any of its Subsidiaries from current or former officers, directors or employees of Arch Western or any of its Subsidiaries (or permitted transferees of such current or former officers, directors or employees), pursuant to the terms of agreements (including employment agreements) or plans (or amendments thereto) approved by the Board of Directors under which such individuals purchase or sell, or are granted the option to purchase or sell, shares of such common stock; provided, however, that: (1) the aggregate amount of such repurchases shall not exceed $2,500,000 in any calendar year and (2) at the time of such repurchase, no other Default or Event of Default shall have occurred and be continuing (or result therefrom); provided further, however, that such repurchases shall be included in the calculation of the amount of Restricted Payments; (e) so long as no Default or Event of Default has occurred and is continuing and Arch Western is a limited liability company, make distributions to the ARCO Member (as defined in the LLC Agreement), with respect to any period after March 31, 2003, not to exceed the Tax Amount allocated to such member under the LLC Agreement for such period; provided, however, that such distributions shall be included in the calculation of the amount of Restricted Payments; (f) so long as no Default or Event of Default has occurred and is continuing, make distributions of the Preferred Return (as defined in the LLC Agreement) to the ARCO Member (as defined in the LLC Agreement) pursuant to the LLC Agreement in effect on the Issue Date; provided, however, that such distribution shall be included in the calculation of the amount of Restricted Payments; and (g) so long as (i) no Default or Event of Default has occurred and is continuing and (ii) Arch Western could incur at least $1.00 of additional Debt pursuant to clause (l) of the first paragraph of Section 4.06 of this Indenture make loans or advances in cash to Arch Coal out of Available Cash as of the date of such loan or advance; provided, however, that such loans or advances shall be included in the calculation of the amount of Restricted Payments. Notwithstanding the prior two paragraphs, any Restricted Payment to, or Permitted Investments in, Arch Coal or any of its Affiliates (other than Arch Western or a Restricted Subsidiary) shall be in the form of a loan for cash which shall be evidenced by Arch Coal Notes that are immediately pledged to the Trustee on behalf of the Holders. SECTION 4.09. Limitation on Asset Sales. Arch Western shall not, and shall not permit any Restricted Subsidiary, to, directly or indirectly, sell, transfer or otherwise dispose of (including by means of a merger, consolidation or similar transaction) any shares of Capital Stock of the Issuer, Arch Western Notes or the Arch Coal Notes. Arch Western shall 50 not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Sale unless: (a) Arch Western or such Restricted Subsidiary receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the Property subject to such Asset Sale; (b) at least 75% of the consideration paid to Arch Western or such Restricted Subsidiary in connection with such Asset Sale is in the form of cash or Cash Equivalents or the assumption by the purchaser of liabilities of Arch Western or any Restricted Subsidiary (other than contingent liabilities or liabilities that are by their terms subordinated to the Notes) as a result of which Arch Western and the Restricted Subsidiaries are no longer obligated with respect to such liabilities; and (c) Arch Western delivers an Officers' Certificate to the Trustee certifying that such Asset Sale complies with the foregoing clauses (a) and (b). The Net Available Cash (or any portion thereof) from Asset Sales may be applied by Arch Western or a Restricted Subsidiary to the extent Arch Western or such Restricted Subsidiary elects (or is required by the terms of any Debt) to: (a) Repay any Debt of Arch Western or such Restricted Subsidiary (other than Subordinated Obligations); or (b) reinvest in Additional Assets (including by means of an Investment in Additional Assets by a Restricted Subsidiary with Net Available Cash received by Arch Western or another Restricted Subsidiary). Any Net Available Cash from an Asset Sale (other than an Asset Sale consisting of all of the Capital Stock of Canyon Fuel or Mountain Coal Company, L.L.C.) not applied in accordance with the preceding paragraph within 365 days from the date of the receipt of such Net Available Cash or that is not segregated from the general funds of Arch Western for investment in identified Additional Assets in respect of a project that shall have been commenced, and for which binding contractual commitments have been entered into, prior to the end of such 365-day period and that shall not have been completed or abandoned shall constitute "Excess Proceeds;" provided, however, that the amount of any Net Available Cash that ceases to be so segregated as contemplated above and any Net Available Cash that is segregated in respect of a project that is abandoned or completed shall also constitute "Excess Proceeds" at the time any such Net Available Cash ceases to be so segregated or at the time the relevant project is so abandoned or completed, as applicable; provided further, however, that the amount of any Net Available Cash that continues to be segregated for investment and that is not actually reinvested within twenty-four months from the date of the receipt of such Net Available Cash shall also constitute "Excess Proceeds." Any Net Available Cash from an Asset Sale consisting of all of the Capital Stock of Canyon Fuel or Mountain Coal Company, L.L.C. not applied in accordance with the preceding paragraph within 365 days from the date of the receipt of such Net Available Cash shall be segregated from the general funds of Arch Western and invested in cash or Cash Equivalents pending application in accordance with the preceding paragraph. 51 When the aggregate amount of Excess Proceeds (including income earned on such Excess Proceeds) exceeds $20,000,000, the Issuer will be required to make an offer to repurchase (the "Prepayment Offer") the Notes, which offer shall be in the amount of the Allocable Excess Proceeds (rounded to the nearest $1,000), on a pro rata basis according to principal amount, at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the repurchase date (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant interest payment date), in accordance with the procedures (including prorating in the event of oversubscription) set forth in this Indenture. To the extent that any portion of the amount of Net Available Cash remains after compliance with the preceding sentence and provided that all Holders of Notes have been given the opportunity to tender their Notes for repurchase in accordance with this Indenture, Arch Western or such Restricted Subsidiary may use such remaining amount for any purpose permitted by this Indenture, and the amount of Excess Proceeds will be reset to zero. The term "Allocable Excess Proceeds" shall mean the product of: (a) the Excess Proceeds and (b) a fraction, (i) the numerator of which is the aggregate principal amount of the Notes outstanding on the date of the Prepayment Offer, and (ii) the denominator of which is the sum of the aggregate principal amount of the Notes outstanding on the date of the Prepayment Offer and the aggregate principal amount of other Debt of Arch Western outstanding on the date of the Prepayment Offer that is pari passu in right of payment with the Arch Western Guarantee and subject to terms and conditions in respect of Asset Sales similar in all material respects to this covenant and requiring Arch Western to make an offer to repurchase such Debt at substantially the same time as the Prepayment Offer. Within five business days after the Issuer is obligated to make a Prepayment Offer as described in the preceding paragraph, the Issuer shall send a written notice, by first-class mail, to the Holders of Notes, accompanied by such information regarding Arch Western and its Subsidiaries as the Issuer in good faith believes will enable such Holders to make an informed decision with respect to such Prepayment Offer. Such notice shall state, among other things, the purchase price and the repurchase date, which shall be, subject to any contrary requirements of applicable law, a business day no earlier than 30 days nor later than 60 days from the date such notice is mailed. The Issuer will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to this covenant. To the extent that the provisions of any securities laws or regulations conflict with provisions of this covenant, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue thereof. 52 SECTION 4.10. Limitation on Transactions with Affiliates. Arch Western shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, conduct any business or enter into or suffer to exist any transaction or series of transactions (including the purchase, sale, transfer, assignment, lease, conveyance or exchange of any Property or the rendering of any service) with, or for the benefit of, any Affiliate of Arch Western (an "Affiliate Transaction"), unless: (a) the terms of such Affiliate Transaction are: (1) set forth in writing, (2) in the best interest of Arch Western or such Restricted Subsidiary, as the case may be, and (3) no less favorable to Arch Western or such Restricted Subsidiary, as the case may be, than those that could be obtained in a comparable arm's-length transaction with a Person that is not an Affiliate of Arch Western, (b) if such Affiliate Transaction involves aggregate payments or value in excess of $5,000,000, the Board of Directors (including at least a majority of the disinterested members of the Board of Directors) approves such Affiliate Transaction and, in its good faith judgment, believes that such Affiliate Transaction complies with clauses (a)(2) and (3) of this paragraph as evidenced by a Board Resolution promptly delivered to the Trustee; provided, however, if there are no disinterested members of the Board of Directors, Arch Western shall receive a written opinion from an Independent Financial Advisor described in clause (c) below, and (c) if such Affiliate Transaction involves aggregate payments or value in excess of $25,000,000, Arch Western obtains a written opinion from an Independent Financial Advisor to the effect that the consideration to be paid or received in connection with such Affiliate Transaction is fair, from a financial point of view, to Arch Western and its Restricted Subsidiaries. Notwithstanding the foregoing limitation, Arch Western or any Restricted Subsidiary may enter into or suffer to exist the following: (a) any transaction or series of transactions between Arch Western and one or more Restricted Subsidiaries or between two or more Restricted Subsidiaries in the ordinary course of business, provided that no more than 5% of the total voting power of the Voting Stock (on a fully diluted basis) of any such Restricted Subsidiary is owned by an Affiliate of Arch Western (other than a Restricted Subsidiary); (b) any Restricted Payment (other than an Investment) permitted to be made pursuant to the first paragraph of Section 4.08 of this Indenture; (c) the payment of compensation (including amounts paid pursuant to employee benefit plans) for the personal services of officers, directors and employees of Arch Western or any of its Restricted Subsidiaries, so long as the Board of Directors in good faith shall have 53 approved the terms thereof and deemed the services theretofore or thereafter to be performed for such compensation to be fair consideration therefor; (d) loans and advances to employees made in the ordinary course of business permitted by law and consistent with the past practices of Arch Western or such Restricted Subsidiary, as the case may be, provided that such loans and advances do not exceed $2,500,000 in the aggregate at any one time outstanding; (e) agreements in effect on the Issue Date and described in the offering memorandum dated June 19, 2003, and any modifications, extensions or renewals thereto that are no less favorable to Arch Western or any Restricted Subsidiary than such agreements as in effect on the Issue Date; and (f) the Arch Coal Notes. SECTION 4.11. Change of Control. Upon the occurrence of a Change of Control, each holder of Notes shall have the right to require the Issuer to repurchase all or any part of such holder's Notes pursuant to the offer described below (the "Change of Control Offer") at a purchase price (the "Change of Control Purchase Price") equal to 101% of the principal amount thereof, plus accrued and unpaid interest to the repurchase date (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant interest payment date). If the repurchase date is after a Record Date and on or before the relevant interest payment date, the accrued and unpaid interest, if any, will be paid to the person or entity in whose name the Note is registered at the close of business on that Record Date, and no additional interest will be payable to Holders whose Notes shall be subject to redemption. Within 30 days following any Change of Control, the Issuer shall: (a) cause a notice of the Change of Control Offer to be sent at least once to the Dow Jones News Service or similar business news service in the United States; and (b) send, by first-class mail, with a copy to the Trustee, to each holder of Notes, at such holder's address appearing in the Security Register, a notice stating: (i) that a Change of Control has occurred and a Change of Control Offer is being made pursuant to this Section 4.11 of the Indenture and that all Notes timely tendered will be accepted for payment; (ii) the Change of Control Purchase Price and the repurchase date, which shall be, subject to any contrary requirements of applicable law, a business day no earlier than 30 days nor later than 60 days from the date such notice is mailed; (iii) the circumstances and relevant facts regarding the Change of Control (including information with respect to pro forma historical income, cash flow and capitalization after giving effect to the Change of Control); and 54 (iv) the procedures that Holders of Notes must follow in order to tender their Notes (or portions thereof) for payment, and the procedures that Holders of Notes must follow in order to withdraw an election to tender Notes (or portions thereof) for payment. The Issuer will not be required to make a Change of Control Offer following a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuer and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. The Issuer shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this covenant, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue of such compliance. SECTION 4.12. Limitation on Sale and Leaseback Transactions. Arch Western shall not, and shall not permit any of its Restricted Subsidies to, enter into any Sale and Leaseback Transaction with respect to any Property unless: (a) Arch Western or such Restricted Subsidiary would be entitled to: (i) Incur Debt in an amount equal to the Attributable Debt with respect to such Sale and Leaseback Transaction pursuant to Section 4.06 of this Indenture and (ii) create a Lien on such Property securing such Attributable Debt without also securing the Notes or the applicable Note Guarantee pursuant to Section 4.07 of this Indenture and (b) such Sale and Leaseback Transaction is effected in compliance with Section 4.09 of this Indenture. SECTION 4.13. Guarantees by Restricted Subsidiaries. If the Company acquires or creates another Domestic Subsidiary after the Issue Date, then that newly acquired or created Subsidiary will become a Subsidiary Guarantor and execute a supplemental indenture within 10 days of the date on which it was created or acquired or became a Subsidiary; provided, however, that all Subsidiaries that have been properly designated as Unrestricted Subsidiaries in accordance with this Indenture for so long as they continue to constitute Unrestricted Subsidiaries will not have to become a Subsidiary Guarantor pursuant to this Section 4.13. In addition, Arch Western shall not permit any Restricted Subsidiary that is not a Guarantor, directly or indirectly, to Guarantee or secure the payment of any other Debt of Arch Western or any of its Restricted Subsidiaries unless such Restricted Subsidiary simultaneously executes and delivers a supplemental indenture to the Indenture providing for a Subsidiary Guarantee of the payment of the Notes by such Restricted Subsidiary; provided that this paragraph shall not be applicable to: 55 (i) any Guarantee of any Restricted Subsidiary that existed at the time such Person became a Restricted Subsidiary and was not incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary; (ii) any Guarantee arising under or in connection with performance bonds, indemnity bonds, surety bonds or letters of credit or bankers' acceptances; or (iii) Permitted Liens. If the Guaranteed Debt is a Subordinated Obligation, the Guarantee of such Guaranteed Debt must be subordinated in right of payment to the Subsidiary Guarantee to at least the extent that the Guaranteed Debt is subordinated to the Notes, or the applicable Subsidiary Guarantee. SECTION 4.14. Limitation on Restrictions on Distributions from Restricted Subsidiaries. Arch Western shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create or otherwise cause or suffer to exist any consensual restriction on the right of any Restricted Subsidiary to: (a) pay dividends, in cash or otherwise, or make any other distributions on or in respect of its Capital Stock, or pay any Debt or other obligation owed, to Arch Western or any other Restricted Subsidiary, (b) make any loans or advances to Arch Western or any other Restricted Subsidiary, or (c) transfer any of its Property to Arch Western or any other Restricted Subsidiary. (d) The foregoing limitations will not apply: (i) with respect to clauses (a), (b) and (c), to restrictions: (1) in effect on the Issue Date (including, without limitation, restrictions pursuant to the Notes and the Indenture); (2) relating to Debt of a Restricted Subsidiary of Arch Western and existing at the time it became a Restricted Subsidiary if such restriction was not created in connection with or in anticipation of the transaction or series of transactions pursuant to which such Restricted Subsidiary became a Restricted Subsidiary or was acquired by Arch Western, or (3) that result from any amendment, restatement, renewal or replacement of an agreement referred to in clause (1)(A) or (B) above or in clause (2)(A) or (B) below, provided such restrictions are not less favorable, taken as a whole, to the Holders of Notes than those under the agreement evidencing the Debt so Refinanced, and (ii) with respect to clause (c) only, to restrictions: 56 (1) relating to Debt that is permitted to be Incurred and secured without also securing the Notes pursuant to Section 4.06 and 4.07 of this Indenture that limit the right of the debtor to dispose of the Property securing such Debt, (2) encumbering Property at the time such Property was acquired by Arch Western or any of its Restricted Subsidiaries, so long as such restrictions relate solely to the Property so acquired and were not created in connection with or in anticipation of such acquisition, (3) resulting from customary provisions restricting subletting or assignment of leases or customary provisions in other agreements that restrict assignment of such agreements or rights thereunder, or (4) customary restrictions contained in asset sale agreements limiting the transfer of such Property pending the closing of such sale. SECTION 4.15. Designation of Unrestricted and Restricted Subsidiaries. The Board of Directors of the Issuer may designate any Restricted Subsidiary (other than the Issuer) to be an Unrestricted Subsidiary if that designation (which would constitute an Investment in such Subsidiary) would not result in a breach of Section 4.08 of this Indenture or otherwise cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by Arch Western and its Restricted Subsidiaries in the Subsidiary properly designated will be deemed to be an Investment made as of the time of the designation as set forth under the definition of "Investment" and will reduce the amount available for Restricted Payments under the first paragraph of Section 4.08 of this Indenture or Permitted Investments, as determined by Arch Western. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors may also designate any Subsidiary of Arch Western to be an Unrestricted Subsidiary if: (a) the Subsidiary to be so designated does not own any Capital Stock or Debt of, or own or hold any Lien on any Property of, Arch Western or any other Restricted Subsidiary and is not required to be a Guarantor pursuant to this Indenture, and (b) either: (i) the Subsidiary to be so designated has total assets of $1,000 or less, or (ii) such designation is effective immediately upon such entity becoming a Subsidiary of Arch Western. Unless so designated as an Unrestricted Subsidiary, any Person that becomes a Subsidiary of Arch Western will be classified as a Restricted Subsidiary; provided, however, that such Subsidiary shall not be designated a Restricted Subsidiary and shall be automatically classified as an Unrestricted Subsidiary if either of the requirements set forth in clauses (x) 57 and (y) of the second immediately following paragraph will not be satisfied after giving pro forma effect to such classification or if such Person is a Subsidiary of an Unrestricted Subsidiary. In addition, neither Arch Western nor any of its Restricted Subsidiaries shall at any time be directly or indirectly liable for any Debt that provides that the holder thereof may (with the passage of time or notice or both) declare a default thereon or cause the payment thereof to be accelerated or payable prior to its Stated Maturity upon the occurrence of a default with respect to any Debt, Lien or other obligation of any Unrestricted Subsidiary (including any right to take enforcement action against such Unrestricted Subsidiary). The Board of Directors may designate any Unrestricted Subsidiary to be a Restricted Subsidiary if, immediately after giving pro forma effect to such designation, (x) Arch Western could Incur at least $1.00 of additional Debt pursuant to clause (1) of the first paragraph of Section 4.06 of this Indenture and (y) no Default or Event of Default shall have occurred and be continuing or would result therefrom. Any such designation or redesignation by the Board of Directors will be evidenced by filing with the Trustee a Board Resolution giving effect to such designation or redesignation and an Officers' Certificate that: (a) certifies that such designation or redesignation complies with the foregoing provisions, and (b) gives the effective date of such designation or redesignation, such filing with the Trustee to occur within 45 days after the end of the fiscal quarter of Arch Western in which such designation or redesignation is made (or, in the case of a designation or redesignation made during the last fiscal quarter of Arch Western's fiscal year, within 90 days after the end of such fiscal year). SECTION 4.16. Payment of Taxes and Other Claims. Arch Western and the Issuer will pay or discharge and shall cause each of the Subsidiaries to pay or discharge, or cause to be paid or discharged, before the same shall become delinquent (a) all material taxes, assessments and governmental charges levied or imposed upon (i) Arch Western, the Issuer or any such Subsidiary, (ii) the income or profits of any such Subsidiary which is a corporation or (iii) the property of Arch Western, the Issuer or any such Subsidiary and (b) all material lawful claims for labor, materials and supplies that, if unpaid, might by law become a Lien upon the property of the Issuer or any such Subsidiary; provided, however, that Arch Western and the Issuer shall not be required to pay or discharge, or cause to be paid or discharged, any such tax, assessment, charge or claim the amount, applicability or validity of which is being contested in good faith by appropriate proceedings and for which adequate reserves have been established. SECTION 4.17. Reports to Holders. Notwithstanding that Arch Coal or Arch Western may not be subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, Arch Coal and Arch Western shall file with the Commission and provide the 58 Trustee and Holders of Notes with such annual reports and such information, documents and other reports as are specified in Sections 13 and 15(d) of the Exchange Act and applicable to a U.S. corporation subject to such Sections, such information, documents and reports to be so filed with the Commission and provided at the times specified for the filing of such information, documents and reports under such Sections; provided, however, that Arch Coal and Arch Western shall not be so obligated to file such information, documents and reports with the Commission if the Commission does not permit such filings; provided further, however, that Arch Coal and Arch Western will be required to provide to the Trustee and the Holders of Notes any such information, documents or reports that are not are so filed. SECTION 4.18. Legal Existence. Subject to Article Five, Arch Western shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence, and the corporate, partnership or other existence of each Restricted Subsidiary, in accordance with the respective organizational documents (as the same may be amended from time to time) of each Restricted Subsidiary and the material rights (charter and statutory) and franchises of Arch Western and the Restricted Subsidiaries; provided that Arch Western shall not be required to preserve any such right, franchise, or the corporate, partnership or other existence of any of its Restricted Subsidiaries if the preservation thereof is no longer desirable in the conduct of the business of Arch Western and its Restricted Subsidiaries taken as a whole and that the loss thereof is not adverse in any material respect to the Holders. SECTION 4.19. Waiver of Stay, Extension or Usury Laws. Arch Western, the Issuer and each of the Subsidiary Guarantors covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, or plead (as a defense or otherwise) or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law which would prohibit or forgive any of Arch Western, the Issuer and the Subsidiary Guarantors from paying all or any portion of the principal of, premium, if any, and/or interest on the Notes or the Note Guarantees as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that they may lawfully do so) each of Arch Western, the Issuer and the Subsidiary Guarantors hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. SECTION 4.20. Further Instruments and Acts. Upon request of the Trustee (but without imposing any duty or obligation of any kind on the Trustee to make any such request), the Issuer and the Subsidiary Guarantors shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture. SECTION 4.21. Covenant Termination. Upon and after the first date that (a) the Notes have Investment Grade Ratings from both Ratings Agencies and (b) no Default has occurred and is continuing hereunder, Arch Western and its Restricted Subsidiaries will not be subject to the provisions of this Indenture described under Sections 4.06, 4.08, 4.09, 4.10, clause (a)(i) and (b) of Section 4.12, 4.14, 4.15 and clause (b)(iv) of Section 5.01 hereof. 59 ARTICLE FIVE CONSOLIDATION, MERGER OR SALE OF ASSETS SECTION 5.01. Consolidation, Merger or Sale of Assets. (a) The Issuer shall not merge, consolidate or amalgamate with or into any other Person. Arch Western shall not: (i) consolidate with or merge with or into any Person (other than a merger of a Wholly Restricted Subsidiary of Arch Western into Arch Western); or (ii) in a single transaction or through a series of transactions, sell, assign, convey, transfer, lease or otherwise dispose of all or substantially all of its properties and assets to any Person or Persons, if such transaction or series of transactions, in the aggregate, would result in the sale, assignment, conveyance, transfer, lease or other disposition of all or substantially all of the Property of Arch Western to any other Person or Persons. (b) Section (a) above shall not apply to Arch Western if: (i) at the time and immediately after giving effect to any such consolidation, merger, transaction or series of transactions, either Arch Western shall be the Surviving Person or the Person (if other than Arch Western) formed by such consolidation or into which Arch Western is merged or the Person that acquires by sale, assignment, conveyance, transfer, lease or other disposition all or substantially all of Arch Western's Property: (1) shall be a limited liability company or a corporation duly organized and validly existing under the laws of the United States of America, any state thereof or the District of Columbia; and (2) expressly assumes (if other than Arch Western), by a supplemental indenture in form satisfactory to the Trustee, Arch Western's obligations under the Notes, this Indenture, the Arch Western Guarantee, the Security Documents and the Registration Rights Agreement, and the Notes, this Indenture, the Arch Western Guarantee, the Security Documents and the Registration Rights Agreement remain in full force and effect as so supplemented; (ii) in the case of a sale, transfer, assignment, lease, conveyance or other disposition of all or substantially all the Property, such Property shall have been transferred as an entirety or virtually as an entirety to one Person; (iii) immediately before and after giving effect to such transaction or series of transactions on a pro forma basis treating any Debt that becomes, or is anticipated to become, an obligation of the Surviving Person or any Restricted Subsidiary as a result of such transaction or series of transactions as having been Incurred by the Surviving Person or such Restricted Subsidiary at the time of such transaction or series of transactions), no Default or Event of Default shall have occurred and be continuing; 60 (iv) immediately after giving effect to any such consolidation, merger, transaction or series of transactions on a pro forma basis (on the assumption that the transaction or series of transactions occurred on the first day of the four-quarter period immediately prior to the consummation of such transaction or series of transactions with the appropriate adjustments with respect to the transaction or series of transactions being included in such pro forma calculation), the Surviving Person could incur at least $1.00 of additional Debt (other than Permitted Debt) in accordance with Section 4.06 hereto; (v) at the time of and immediately after giving effect to any such consolidation, merger, transaction or series of transactions, Arch Western is able to make payments on the Notes without being obligated to deduct or withhold any taxes or duties of whatever nature levied by any jurisdiction in which Arch Western, any Guarantor, any Subsidiary or any Surviving Person is organized, engaged in business, resident for tax purposes or generally subject to tax on a net income basis or from or through which payment is made; (vi) at the time of any such consolidation, merger, transaction or series of transactions, Arch Western or the Surviving Person shall have delivered to the Trustee, in form and substance satisfactory to the Trustee, an Officers' Certificate (attaching the authentic computations to demonstrate compliance with clause (iv) above) and an Opinion of Counsel, each stating that such consolidation, merger, sale, assignment, conveyance, transfer, lease or other disposition, and if a supplemental indenture is required in connection with such transaction, such supplemental indenture, comply with the requirements of this Indenture and that all conditions precedent therein relating to such transaction have been complied with and that this Indenture and the Guarantees constitute legal, valid and binding obligations of the continuing person, enforceable in accordance with their terms; and (vii) Arch Western shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such transaction and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such consolidation, merger, transaction or series of transactions had not occurred. (c) Arch Western shall not permit any Subsidiary Guarantor to consolidate with or merge with or into any Person or sell, assign, transfer, convey or otherwise dispose of, all or substantially all of its Property, in one or more related transactions, to any Person unless Arch Western has delivered to the Trustee an Officers' Certificate and Opinion of Counsel stating that such consolidation, merger, transaction or series of transactions complies with the following conditions and each of the following conditions is satisfied: (i) the other Person is Arch Western or any Wholly Owned Restricted Subsidiary that is a Subsidiary Guarantor or becomes a Subsidiary Guarantor concurrently with the transaction; or (ii) (1) either (x) the Subsidiary Guarantor shall be the Surviving Person or (y) the entity formed by such consolidation or into which the Subsidiary Guarantor is 61 merged, expressly assumes, by a Guarantee or a supplemental indenture in form satisfactory to the Trustee, executed and delivered to the Trustee by such surviving Person the due and punctual performance and observance of all the obligations of such Subsidiary Guarantor under the Subsidiary Guarantee; and (2) the Surviving Person, if other than the Subsidiary Guarantor, is a corporation or limited liability company organized under the laws of the United States, any state thereof or the District of Columbia and immediately after giving effect to the transaction and any related Incurrence of Debt of, no Default or Event of Default shall have occurred and be continuing; or (iii) the transaction constitutes a sale or other disposition (including by way of consolidation or merger) of the Subsidiary Guarantor or the sale or disposition of all or substantially all the assets of the Subsidiary Guarantor (in each case other than to another Subsidiary Guarantor) and at the time of such transaction after giving pro forma effect thereto, the provisions of clause (6)(iv) of this covenant would be satisfied, the transaction is otherwise permitted by this Indenture and the Subsidiary Guarantor is released from its Subsidiary Guarantee at the time of such transaction in accordance with this Indenture. SECTION 5.02. Successor Substituted.

(b) If a Default or an Event of Default occurs and is continuing and is known to a Trust Officer of the Trustee, the Trustee shall mail to each Holder notice of the Default or Event of Default within five business days after its occurrence. Except in the case of a Default or an Event of Default in payment of principal of, premium, if any, on the Notes or interest, if any, on any Note, the Trustee may withhold the notice to the Holders if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of the Holders. The Issuer shall also notify the Trustee within five Business Days of the occurrence of any Event of Default. SECTION 6.02. Acceleration. (a) If an Event of Default with respect to the Notes (other than an Event of Default specified in Section 6.01(a)(vii) or (viii) above) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding by written notice to Arch Western or the Issuer (and to the Trustee if such notice is given by the Holders) may and the Trustee, upon the written request of such Holders shall, declare the principal amount of all of the outstanding Notes immediately due and payable, and upon any such declaration such principal amount in respect of the Notes shall become immediately due and payable. 64 (b) If an Event of Default specified in Section 6.01(a)(vii) or (viii) above occurs and is continuing, then the principal amount of all of the outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. (c) At any time after a declaration of acceleration under this Indenture, but before a judgment or decree for payment of the money due has been obtained by the Trustee, the Holders of a majority in aggregate principal amount of the outstanding Notes, by written notice to Arch Western or the Issuer and the Trustee, may waive all past Defaults and rescind and annul such declaration of acceleration and its consequences if: (i) The Issuer or the Guarantors have paid or deposited with the Trustee a sum sufficient to pay: (1) all overdue interest, if any, on all Notes then outstanding; (2) all unpaid principal of and premium, if any, on any outstanding Notes that has become due otherwise than by such declaration of acceleration and interest thereon at the rate borne by the Notes; (3) to the extent that payment of such interest is lawful, interest upon overdue interest, if any, at the rate borne by the Notes; and (4) all sums paid or advanced by the Trustee under this Indenture and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; (ii) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (iii) all Events of Default, other than the non-payment of amounts of principal of, premium, if any, and interest, if any, on the Notes that has become due solely by such declaration of acceleration, have been cured or waived as provided in Section 6.04. No such rescission shall affect any subsequent default or impair any right consequent thereon. (d) Notwithstanding Section 6.02(c) above, in the event of a declaration of acceleration in respect of the Notes because of an Event of Default specified in Section 6.01(a)(v) shall have occurred and be continuing, such declaration of acceleration shall be automatically annulled if the Indebtedness that is the subject of such Event of Default has been discharged or the Holders thereof have rescinded their declaration of acceleration in respect of such Indebtedness, and written notice of such discharge or rescission, as the case may be, shall have been given to the Trustee by the Issuer and countersigned by the Holders of such Indebtedness or a trustee, fiduciary or agent for such Holders, within 30 days after such declaration of acceleration in respect of the Notes, and no other Event of Default has occurred during such 30-day period which has not been cured or waived during such period. 65 (e) Subject to the Article Seven this Indenture relating to the duties of the Trustee, in case an Event of Default shall occur and be continuing, the Trustee will be under no obligation to exercise any of its rights or powers under this Indenture at the request or direction of any of the Holders, unless such Holders shall have offered to the Trustee reasonable indemnity. Subject to such provisions for the indemnification of the Trustee, the Holders of at least a majority in aggregate principal amount of the Notes then outstanding will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Notes. No holder of Notes will have any right to institute any proceeding with respect to this Indenture, or for the appointment of a receiver or trustee, or for any remedy thereunder, unless: (i) such holder has previously given to the Trustee written notice of a continuing Event of Default; (ii) the registered Holders of at least 25% in aggregate principal amount of the Notes then outstanding have made a written request and offered reasonable indemnity to the Trustee to institute such proceeding as Trustee; and (iii) the Trustee shall not have received from the registered Holders of at least a majority in aggregate principal amount of the Notes then outstanding a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days. However, such limitations do not apply to a suit instituted by a holder of any Note for enforcement of payment of the principal of, and premium, if any, or interest on, such Note on or after the respective due dates expressed in such Note. SECTION 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. All rights of action and claims under this Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name and as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders in respect of which such judgment has been recovered. SECTION 6.04. Waiver of Past Defaults. The Holders of not less than a majority in principal amount of the outstanding Notes may on behalf of the Holders of all the Notes waive any past Default hereunder and its consequences, except a Default: 66 (a) in respect of the payment of the principal of (or premium, if any), or interest on, any Note, or (b) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each outstanding Note affected. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. SECTION 6.05. Control by Majority. The Holders of not less than a majority in aggregate principal amount of the Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee under this Indenture; provided that: (a) the Trustee may refuse to follow any direction that conflicts with law, this Indenture or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders not joining in the giving of such direction; (b) the Trustee may refuse to follow any direction that the Trustee determines is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability; and (c) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking or not taking any action hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. SECTION 6.06. Limitation on Suits. A Holder may not pursue any remedy with respect to this Indenture or the Notes unless: (a) the Holder has previously given the Trustee written notice of a continuing Event of Default; (b) the Holders of at least 25% in aggregate principal amount of outstanding Notes shall have made a written request to the Trustee to pursue such remedy; (c) such Holder or Holders offer the Trustee indemnity reasonably satisfactory to the Trustee against any costs, liability or expense; (d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and 67 (e) during such 60-day period, the Holders of a majority in aggregate principal amount of the outstanding Notes do not give the Trustee a direction that is inconsistent with the request. The limitations in the foregoing provisions of this Section 6.06, however, do not apply to a suit instituted by a Holder for the enforcement of the payment of the principal of, premium, if any, or interest, if any, on such Note on or after the respective due dates expressed in such Note. A Holder may not use this Indenture to prejudice the rights of any other Holder or to obtain a preference or priority over another Holder. SECTION 6.07. Unconditional Right of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of, premium, if any, and interest, if any, on the Notes held by such Holder, on or after the respective due dates expressed in the Notes, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. SECTION 6.08. Collection Suit by Trustee. The Issuer covenants that if default is made in the payment of: (a) any installment of interest on any Note when such interest becomes due and payable and such default continues for a period of 30 days, or (b) the principal of (or premium, if any, on) any Note at the Maturity thereof, the Issuer shall, upon demand of the Trustee, pay to the Trustee for the benefit of the Holders of such Notes, the whole amount then due and payable on such Notes for principal (and premium, if any), and interest, and interest on any overdue principal (and premium, if any) and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installment of interest, at the rate borne by the Notes, and, in addition thereto, such further amount as shall be sufficient to cover the amounts provided for in Section 7.07 and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. (c) If the Issuer fails to pay such amounts forthwith upon such demand, the Trustee, in its own name as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Issuer or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Issuer or any other obligor upon the Notes, wherever situated. SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07) and the Holders allowed in any judicial proceedings relative to the Issuer or any Guarantor, their creditors or their property and, unless prohibited by law or 68 applicable regulations, may vote on behalf of the Holders at their direction in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.07. Nothing herein contained shall be deemed to empower the Trustee to authorize or consent to, or accept or adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 6.10. Application of Money Collected. If the Trustee collects any money or other property (or the same is distributed) pursuant to this Article Six, it shall pay out the money or property in the following order: FIRST: to the Trustee (including any predecessor Trustee)for amounts due under Section 7.07; SECOND: to Holders for amounts due and unpaid on the Notes for principal of, premium, if any, and interest, if any, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, if any, respectively; and THIRD: to the Issuer, any Guarantor or any other obligors of the Notes, as their interests may appear, or as a court of competent jurisdiction may direct. The Trustee may fix a Record Date and payment date for any payment to Holders pursuant to this Section 6.10. At least 15 days before such Record Date, the Issuer shall mail to each Holder and the Trustee a notice that states the Record Date, the payment date and amount to be paid. SECTION 6.11. Undertaking for Costs. A court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in the suit of an undertaking to pay the costs of such suit, and such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by Holders of more than 10% in aggregate principal amount of the outstanding Notes or to any suit by any Holder pursuant to Section 6.07. SECTION 6.12. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Issuer, any Guarantor, the Trustee and the Holders shall be 69 restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. SECTION 6.13. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.07, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. SECTION 6.14. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article Six or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. SECTION 6.15. Record Date. The Issuer may set a Record Date for purposes of determining the identity of Holders entitled to vote or to consent to any action by vote or consent authorized or permitted by Sections 6.04, 6.05 and 12.04. Unless this Indenture provides otherwise, such Record Date shall be the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee pursuant to Section 2.05 prior to such solicitation. SECTION 6.16. Waiver of Stay or Extension Laws. The Issuer covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Issuer (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted. ARTICLE SEVEN TRUSTEE SECTION 7.01. Duties of Trustee. (a) if an Event of Default has occurred and is continuing of which a Trust Officer of the Trustee has actual knowledge, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs; (b) except during the continuance of an Event of Default of which a Trust Officer of the Trustee has actual knowledge: (i) the Trustee undertakes to perform such duties and only 70 such duties as are specifically set forth in this Indenture and no others and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. In the case of any such certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine same to determine whether they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein); (c) the Trustee shall not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that: (i) this paragraph does not limit the effect of paragraph (b) of this Section 7.01; (ii) the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and (iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05; (d) the Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuer or any Guarantor. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law; (e) no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it; and (f) whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 7.01 and to the provisions of the TIA. SECTION 7.02. Certain Rights of Trustee. (a) Subject to Section 7.01: (i) the Trustee may rely, and shall be protected in acting or refraining from acting, upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper person; (ii) before the Trustee acts or refrains from acting, it may require an Officers' Certificate or an Opinion of Counsel, which shall conform to Section 13.05. The Trustee 71 shall not be liable for any action it takes or omits to take in good faith in reliance on such certificate or opinion; (iii) the Trustee may act through its attorneys and agents and shall not be responsible for the misconduct or negligence of any attorney or agent appointed with due care by it hereunder; (iv) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction; (v) the Trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within its rights or powers, provided that the Trustee's conduct does not constitute negligence or bad faith; (vi) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers' Certificate; and (vii) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuer personally or by agent or attorney. (viii) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder (including its capacity under the Note Pledge Agreement), and each agent, custodian and other Person employed to act hereunder and under the Note Pledge Agreement; and the permissive right of the Trustee to take any action under this Indenture or under any other agreement in connection herewith shall not be construed as a duty; (ix) each Guarantor shall pay on demand to the Trustee any and all costs, fees and expenses (including without limitation, reasonable legal fees of counsel) incurred by the Trustee in enforcing any rights under any Guarantee; (x) the Trustee shall not be deemed to have notice of any Default or Event of Default unless a Trust Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture; 72 (xi) the permissive right of the Trustee to take any action under this Indenture or under any other agreement in connection herewith shall not be construed as a duty; (xii) unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Issuer shall be sufficient if signed by an Officer of the Issuer; and (xiii) the trustee may consult with counsel and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. (b) The Trustee may request that the Issuer deliver an Officers' Certificate setting forth the names of the individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers' Certificate may be signed by any person authorized to sign an Officers' Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded. SECTION 7.03. Individual Rights of Trustee. The Trustee, any Paying Agent, any Registrar or any other agent of the Issuer or of the Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes and, subject to TIA Sections 310(b) and 311, may otherwise deal with the Issuer with the same rights it would have if it were not Trustee, Paying Agent, Registrar or such other agent. SECTION 7.04. Trustee's Disclaimer. The recitals contained herein and in the Notes, except for the Trustees certificates of authentication, shall be taken as the statements of the Issuer, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Notes and perform its obligations hereunder and agrees that the statements made by it in a Statement of Eligibility on Form T-1 supplied to the Issuer will be true and accurate, subject to the qualifications set forth therein. The Trustee shall not be accountable for the use or application by the Issuer of Notes or the proceeds thereof. It shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the issuance or sale of the Notes or pursuant to this Indenture other than its certificate of authentication. Beyond the exercise of reasonable care in the custody thereof, the Trustee shall have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and the Trustee shall not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any security interest in the Collateral. The Trustee shall be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property and shall not be liable or responsible for any loss or diminution 73 in the value of any of the Collateral, by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Trustee in good faith. The Trustee shall not be responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, except to the extent such action or omission constitutes gross negligence or willful misconduct on the part of the Trustee, for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title of the Company to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Trustee shall have no duty to ascertain or inquire as to the performance or observance of any of the terms of this Indenture, the Collateral Agency Agreement or the Security Documents by the Issuer, any secured creditors or secured creditors' representatives, or the Collateral Trustee or any collateral agent. SECTION 7.05. Notice of Defaults. If any Default or any Event of Default occurs and is continuing and if such Default or Event of Default is known to the Trustee, the Trustee shall mail to each Holder in the manner and to the extent provided in TIA Section 313(c) notice of the Default or Event of Default within 45 days after it occurs, unless such Default or Event of Default has been cured; provided, however, that, except in the case of a default in the payment of the principal of, premium, if any, or interest on any Note, the Trustee shall be protected in withholding such notice if and so long as a committee of its Trust Officers in good faith determine that the withholding of such notice is in the interest of the Holders. The Trustee shall not be deemed to have knowledge of a Default unless a Trust Officer has actual knowledge of such Default or written notice of such Default has been received by the Trustee at its Corporate Trust Office in New York, New York, and such notice references the Notes and this Indenture SECTION 7.06. Reports by Trustee to Holders. Within 60 days after January 1 of each year commencing with the first January 1 after the Issue Date, the Trustee shall transmit to the Holders, in the manner and to the extent provided in TIA Section 313(c), a brief report dated as of such date that complies with TIA Section 313(a). The Trustee also shall comply with TIA Section 313(b) and (c). The Issuer shall promptly notify the Trustee whenever the Notes become listed on any securities exchange and of any delisting thereof and the Trustee shall comply with TIA Section 313(d). SECTION 7.07. Compensation and Indemnity. The Issuer, failing which each Guarantor, shall pay to the Trustee such compensation as shall be agreed in writing for its services hereunder. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer, failing which each Guarantor, shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and out-of-pocket expenses of the Trustee's agents and counsel. 74 The Issuer, failing which each Guarantor, shall indemnify the Trustee (in any of its capacities in connection with any of the transactions contemplated hereby, including, without limitation, under this Indenture or under the Note Pledge Agreement) and its officers, directors, employees and agents for, and hold it and them harmless from and against any and all loss, liability or expense (including attorneys' fees and expenses) incurred by it or any of them without willful misconduct or negligence on its part arising out of or in connection with the administration of this trust and the performance of its duties hereunder (including the costs and expenses of enforcing this Indenture including this Section 7.07 and of defending itself against any claim, whether asserted by the Issuer, the Guarantors, any Holder or any other Person). The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer or the Guarantors of their obligations hereunder or under the Note Pledge Agreement. The Issuer shall defend the claim and the Trustee shall cooperate in such defense. The Trustee may have separate counsel and the Issuer shall pay the fees and expenses of such counsel. The Issuer need not pay for any settlement made without its consent, which consent may not be unreasonably withheld. The Issuer shall not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee's own willful misconduct or negligence. To secure the Issuer's and each of the Guarantor's payment obligations in this Section 7.07, the Trustee shall have a Lien prior to the Notes upon the Collateral and on all money or property held or collected by the Trustee, hereunder or under the Note Pledge Agreement, in its capacity as Trustee, except money or property held in trust to pay principal of, premium, if any, and interest on particular Notes. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(a)(vii) or (viii) with respect to the Issuer, the Guarantors, or any Restricted Subsidiary, the expenses are intended to constitute expenses of administration under Bankruptcy Law. The Issuer's and each of the Guarantor's obligations under this Section 7.07, including the Lien and claim of the Trustee, and any claim arising hereunder shall survive the resignation or removal of any Trustee, the satisfaction and discharge of the Issuer's or Guarantor's obligations pursuant to Article Eight and any rejection or termination under any Bankruptcy Law, and the termination of this Indenture for any reason, and shall apply with equal force and effect to the Trustee in each of its capacities hereunder and each agent, custodian and other Person employed to act hereunder. "Trustee" for purposes of this Section 7.07 shall include any predecessor Trustee; provided, however, that the negligence or willful misconduct of any Trustee hereunder shall not affect the rights of any other Trustee hereunder. SECTION 7.08. Replacement of Trustee. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section 7.08. 75 The Trustee may resign at any time by so notifying the Issuer. The Holders of a majority in outstanding principal amount of the outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuer. The Issuer shall remove the Trustee if: (a) the Trustee fails to comply with Section 7.10; (b) the Trustee is adjudged bankrupt or insolvent; (c) a receiver or other public officer takes charge of the Trustee or its property; or (d) the Trustee otherwise becomes incapable of acting. If the Trustee resigns or is removed, or if a vacancy exists in the office of Trustee for any reason, the Issuer shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuer. If the successor Trustee does not deliver its written acceptance required by the next succeeding paragraph of this Section 7.08 within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or the Holders of a majority in principal amount of the outstanding Notes may, at the expense of the Issuer, petition any court of competent jurisdiction for the appointment of a successor Trustee. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee. If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or the Holders of at least 25% in outstanding principal amount of the Notes may, at the Issuer's expense, petition any court of competent jurisdiction for the appointment of a successor Trustee at the expense of the Issuer. If the Trustee fails to comply with Section 7.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided that all sums owing to the retiring Trustee hereunder have been paid and subject to the lien provided for in Section 7.07. Notwithstanding the replacement of the Trustee pursuant to this Section 7.08, the Issuer's and the Guarantors' obligations under Section 7.07 shall continue for the benefit of the retiring Trustee. SECTION 7.09. Successor Trustee by Merger. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be 76 otherwise qualified and eligible under this Article Seven, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes. In case at that time any of the Notes shall not have been authenticated, any successor Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor Trustee. In all such cases such certificates shall have the full force and effect which this Indenture provides for the certificate of authentication of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation. SECTION 7.10. Eligibility: Disqualification. The Trustee shall at all times satisfy the requirements of TIA Section 310(a)(1) and (5). The Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. No obligor upon the Notes or Person directly controlling, controlled by, or under common control with such obligor shall serve as trustee upon the Notes. The Trustee shall comply with TIA Section 310(b); provided, however, that there shall be excluded from the operation of TIA Section 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other notes of the Issuer are outstanding if the requirements for such exclusion set forth in TIA Section 310(b)(1) are met. For purposes of Section 310(b)(1) of the TIA and to the extent permitted thereby, the Trustee, in its capacity as trustee in respect of the Securities of any series, shall not be deemed to have a conflict of interest arising from its capacity as trustee in respect of the Securities of any other series. Nothing herein shall prevent the Trustee from filing with the Commission the application referred to in the second to last paragraph of Section 310(b) of the TIA. If the Trustee has or shall acquire a conflicting interest within the meaning of the TIA, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.] SECTION 7.11. Preferential Collection of Claims Against Issuer. The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. SECTION 7.12. Appointment of Co-Trustee. (a) It is the purpose of this Indenture that there shall be no violation of any law of any jurisdiction denying or restricting the right of banking corporations or associations to transact business as trustee in such jurisdiction. It is recognized that in case of litigation under this Indenture or the Agreement, and in particular in case of the enforcement thereof on default, or in the case the Trustee deems that by reason of any present or future law of any jurisdiction it may not exercise any of the powers, rights or remedies herein granted to the Trustee or hold title to the properties, in trust, as herein granted or take any 77 action which may be desirable or necessary in connection therewith, it may be necessary that the Trustee appoint an individual or institution as a separate or co-trustee. The following provisions of this Section 7.12 are adopted to these ends. (b) In the event that the Trustee appoints an additional individual or institution as a separate or co-trustee, each and every remedy, power, right, claim, demand, cause of action, immunity, estate, title, interest and Lien expressed or intended by this Indenture to be exercised by or vested in or conveyed to the Trustee with respect thereto shall be exercisable by and vest in such separate or co-trustee but only to the extent necessary to enable such separate or co-trustee to exercise such powers, rights and remedies, and only to the extent that the Trustee by the laws of any jurisdiction is incapable of exercising such powers, rights and remedies, and every covenant and obligation necessary to the exercise thereof by such separate or co-trustee shall run to and be enforceable by either of them. (c) Should any instrument in writing from the Issuer be required by the separate or co-trustee so appointed by the Trustee for more fully and certainly vesting in and confirming to him or it such properties, rights, powers, trusts, duties and obligations, any and all such instruments in writing shall, on request, be executed, acknowledged and delivered by the Issuer; provided, however, that if an Event of Default shall have occurred and be continuing, if the Issuer does not execute any such instrument within 15 days after request therefor, the Trustees shall be empowered as an attorney-in-fact for the Issuer to execute any such instrument in the Issuer's name and stead. In case any separate or co-trustee or a successor to either shall die, become incapable or acting, resign or be removed, all the estates, properties, rights, powers, trusts, duties and obligations of such separate or co-trustee, so far as permitted by law, shall vest in and be exercised by the Trustee until the appointment of a new trustee or successor to such separate or co-trustee. (d) Each separate trustee and co-trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions: (i) all rights and powers, conferred or imposed upon the Trustee shall be conferred or imposed upon and may be exercised or performed by such separate trustee or co-trustee; and (ii) no trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder. (e) Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the then separate trustees and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to this Indenture and the conditions of this Article Seven. (f) Any separate trustee or co-trustee may at any time appoint the Trustee as its agent or attorney-in-fact with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Indenture on its behalf and in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, 78 properties, rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment of a new or successors trustee. ARTICLE EIGHT DEFEASANCE; SATISFACTION AND DISCHARGE SECTION 8.01. Arch Western and the Issuer's Option to Effect Defeasance or Covenant Defeasance. Arch Western and the Issuer may, at their option by a resolution of the Boards of Directors, at any time, with respect to the Notes, elect to have either Section 8.02 or Section 8.03 be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article Eight. SECTION 8.02. Defeasance and Discharge. Upon Arch Western's and the Issuer's exercise under Section 8.01 of the option applicable to this Section 8.02, Arch Western and the Issuer shall be deemed to have been discharged from its obligations with respect to the Notes on the date the conditions set forth in Section 8.04 are satisfied (hereinafter, "legal defeasance"). For this purpose, such legal defeasance means that Arch Western and the Issuer shall be deemed to have paid and discharged the entire indebtedness represented by the Notes and to have satisfied all its other obligations under the Notes and this Indenture (and the Trustee, at the expense of Arch Western and the Issuer, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of Notes to receive, solely from the trust fund described in Section 8.08 and as more fully set forth in such Section, payments in respect of the principal of (and premium, if any, on) and interest on such Notes when such payments are due, (b) the provisions set forth at Section 8.06 below and (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder. Subject to compliance with this Article Eight, Arch Western and the Issuer may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 below with respect to the Notes. If Arch Western and the Issuer exercise their legal defeasance option, payment of the Notes may not be accelerated because of an Event of Default. SECTION 8.03. Covenant Defeasance. Upon Arch Western's and the Issuer's exercise under Section 8.01 of the option applicable to this Section 8.03, Arch Western and the Issuer shall be released from their respective obligations under any covenant contained in Sections 4.04 through 4.15, 4.17 (other than the covenant to comply with TIA Section 314(a) to the extent that such obligations thereunder cannot be terminated), 5.01(b)(iv) and 6.01((iv),(v),(vi) and (vii) (only with respect to Significant Subsidiaries)) with respect to the Notes on and after the date the conditions set forth below are satisfied (hereinafter, "covenant defeasance"). For this purpose, such covenant defeasance means that, the Issuer may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. 79 SECTION 8.04. Conditions to Defeasance. The legal defeasance option or the covenant defeasance option may be exercised only if: (a) Arch Western or the Issuer irrevocably deposit in trust with the Trustee money or U.S. Government Obligations for the payment of principal of, premium, if any, and interest on the Notes to maturity or redemption, as the case may be; (b) Arch Western or the Issuer delivers to the Trustee a certificate from a nationally recognized firm of independent certified public accountants expressing their opinion that the payments of principal, premium, if any, and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal, premium, if any, and interest when due on all the Notes to be defeased to maturity or redemption, as the case may be; (c) 123 days pass after the deposit is made, and during the 123-day period, no Default described in Section 6.01(vii) and (viii) occurs with respect to Arch Western or the Issuer or any other Person making such deposit which is continuing at the end of the period; (d) no Default or Event of Default has occurred and is continuing on the date of such deposit and after giving effect thereto; (e) such deposit does not constitute a default under any other agreement or instrument binding on Arch Western or any of its Restricted Subsidiaries; (f) Arch Western or the Issuer delivers to the Trustee an Opinion of Counsel to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940; (g) in the case of the legal defeasance option, Arch Western or the Issuer delivers to the Trustee an Opinion of Counsel stating that: (i) Arch Western or the Issuer has received from the Internal Revenue Service a ruling, or (ii) since the date of this Indenture there has been a change in the applicable Federal income tax law, to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same time as would have been the case if such defeasance has not occurred; (h) in the case of the covenant defeasance option, Arch Western or the Issuer delivers to the Trustee an Opinion of Counsel to the effect that the Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred; and 80 (i) Arch Western or the Issuer delivers to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Notes have been complied with as required by this Article Eight.

Notwithstanding Sections 8.01 and 8.03, any obligations of the Issuer and the Guarantors in Sections 2.02 through 2.14, 6.07, 7.07, 7.08, and 8.07 through 8.09 shall survive until the Notes have been paid in full. Thereafter, any obligations of the Issuer and the Guarantors in Sections 7.07, 8.07 and 8.08 shall survive such satisfaction and discharge. Nothing contained in this Article Eight shall abrogate any of the obligations or duties of the Trustee under this Indenture. SECTION 8.07. Acknowledgment of Discharge by Trustee. Subject to Section 8.09, after the conditions of Section 8.02 or 8.03 have been satisfied, the Trustee upon written request shall acknowledge in writing the discharge of all of the Issuer's obligations under this Indenture except for those surviving obligations specified in this Article Eight.

Subject to Sections 7.07, and 8.01 through 8.04, the Trustee and the Paying Agent shall promptly pay to the Issuer upon request set 81 forth in an Officers' Certificate any excess money held by them at any time and thereupon shall be relieved from all liability with respect to such money. The Trustee and the Paying Agent shall pay to the Issuer upon request any money held by them for the payment of principal, premium, if any, that remains unclaimed for two years; provided that the Trustee or Paying Agent before being required to make any payment may cause to be published (a) in The Wall Street Journal or another leading newspaper in New York, New York, (b) through the newswire service of Bloomberg or, if Bloomberg does not then operate, any similar agency or mail to each Holder entitled to such money at such Holder's address (as set forth in the Security Register) notice that such money remains unclaimed and that after a date specified therein (which shall be at least 30 days from the date of such publication or mailing) any unclaimed balance of such money then remaining will be repaid to the Issuer. After payment to the Issuer, Holders entitled to such money must look to the Issuer for payment as general creditors unless an applicable law designates another Person, and all liability of the Trustee and such Paying Agent with respect to such money shall cease. SECTION 8.10. Indemnity for Government Securities.

Arch Western and the Issuer, when authorized by a resolution of the Board of Directors (as evidenced by the delivery of such resolution to the Trustee), any Guarantor and the Trustee may modify, amend or supplement this Indenture, any Guarantee or the Notes without notice to or consent of any Holder to: (a) cure any ambiguity, omission, defect or inconsistency in any manner that is not adverse in any material respect to any holder of the Notes, (b) provide for the assumption by a Surviving Person of the obligations of Arch Western under this Indenture, 82 (c) provide for uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code), (d) add Note Guarantees with respect to the Notes or confirm and evidence the release, termination or discharge of any security or Note Guarantee when such release, termination or discharge is permitted by this Indenture, (e) secure the Notes, add to the covenants of the Issuer or Arch Western for the benefit of the Holders or surrender any right or power conferred upon the Issuer, (f) make any change that does not adversely affect the rights of any holder of the Notes, (g) comply with any requirement of the Commission in connection with the qualification of this Indenture under the Trust Indenture Act, or (h) provide for the issuance of Additional Notes in accordance with this Indenture. SECTION 9.02. With Consent of Holders. (a) Except as provided in Section 9.02(b) below and Section 6.04 and without prejudice to Section 9.01, Arch Western, the Issuer and the Trustee may: (i) amend this Indenture or the Notes, the Note Guarantees or the Security Documents, or (ii) waive compliance by Arch Western and the Issuer with any provision of this Indenture or the Notes, with the written consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding including consents obtained in connection with a tender offer or in exchange for the Notes.

The consent of the Holders is not necessary to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment. After an amendment becomes effective, the Issuer shall mail to each registered holder of the Notes at such holder's address appearing in the Security Register a notice briefly describing such amendment. However, the failure to give such notice to all Holders, or any defect therein, will not impair or affect the validity of the amendment. SECTION 9.03. Compliance with Trust Indenture Act. Every amendment, modification or supplement to this Indenture or the Notes shall be set forth in a supplemental indenture that complies with the TIA as then in effect. SECTION 9.04. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article Nine, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. SECTION 9.05. Notation on or Exchange of Notes. If an amendment, modification or supplement changes the terms of a Note, the Issuer or Trustee may require the 84 Holder to deliver it to the Trustee. The Trustee may place an appropriate notation on the Note and on any Note subsequently authenticated regarding the changed terms and return it to the Holder. Alternatively, if the Issuer so determines, the Issuer in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or to issue a new Note shall not affect the validity of such amendment, modification or supplement. SECTION 9.06. Payment for Consent. Arch Western will not, and will not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any holder of any Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid or is paid to all Holders that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement. SECTION 9.07. Notice of Amendment or Waiver.

The Trustee shall sign all supplemental indentures that comply with the requirements of this Indenture, except that the Trustee may, but need not, sign any supplemental indenture that adversely affects its rights.

Each Guarantor further agrees that the Obligations may be extended or renewed, in whole or in part, without notice or further assent from such Guarantor and that such Guarantor will remain bound under this Article Ten 85 notwithstanding any extension or renewal of any Obligation. All payments under such Guarantee will be made in U.S. Dollars. (b) Each Guarantor hereby agrees that its obligations hereunder shall be as if they were the principal debtor and not merely surety, unaffected by, and irrespective of, any validity, irregularity or unenforceability of any Note or this Indenture, any failure to enforce the provisions of any Note or this Indenture, any waiver, modification or indulgence granted to the Issuer with respect thereto by the Holders or the Trustee, or any other circumstance which may otherwise constitute a legal or equitable discharge of a surety or guarantor (except payment in full); provided, however, that, notwithstanding the foregoing, no such waiver, modification, indulgence or circumstance shall without the written consent of the Guarantor increase the principal amount of a Note or the interest rate thereon or change the currency of payment with respect to any Note, or alter the Stated Maturity thereof. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of merger or bankruptcy of the Issuer, any right to require that the Trustee pursue or exhaust its legal or equitable remedies against the Issuer prior to exercising its rights under the Guarantee (including, for the avoidance of doubt, any right which the Guarantor may have to require the seizure and sale of the assets of the Issuer to satisfy the outstanding principal of, interest on or any other amount payable under each Note prior to recourse against the Guarantor or its assets), protest or notice with respect to any Note or the Debt evidenced thereby and all demands whatsoever, and covenants that the Guarantee will not be discharged with respect to any Note except by payment in full of the principal thereof and interest thereon or as otherwise provided in this Indenture, including Section 10.03. If at any time any payment of principal of, premium, if any, and interest, if any, on such Note is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Issuer, the Guarantor's obligations hereunder with respect to such payment shall be reinstated as of the date of such rescission, restoration or returns as though such payment had become due but had not been made at such times. (c) The Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys' fees) incurred by the Trustee or any Holder in enforcing any rights under this Section 10.01. SECTION 10.02. Subrogation. (a) The Guarantor shall be subrogated to all rights of the Holders against the Issuer in respect of any amounts paid to such Holders by the Guarantor pursuant to the provisions of its Guarantee.

The Guarantor further agrees that, as between themselves, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Section 6.02 for the purposes of their Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Section 6.02, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purposes of this Section 10.02 subject to Section 10.01(c) above. 86 SECTION 10.03. Release of Subsidiary Guarantors. The Guarantee of any Subsidiary Guarantor will be automatically and unconditionally released and discharged upon any of the following: (a) in the event of a sale or other disposition, by way of merger, consolidation or otherwise, of all the Capital Stock of any Subsidiary Guarantor to any Person that is not an Affiliate of Arch Western, such Subsidiary Guarantor will be released and relieved of any obligations under its Subsidiary Guarantee; provided that the Net Available Cash from such sale or other disposition is applied in accordance with the applicable provisions of Section 4.09 of this Indenture; (b) upon the release or discharge of another Guarantee of a Subsidiary Guarantor that resulted in the creation of the Subsidiary Guarantee of such Subsidiary Guarantor, except a discharge or release by or as a result of payment under such other Guarantee pursuant to Section 4.13, such Subsidiary Guarantor will be released and relieved of any obligations under its Subsidiary Guarantee; or (c) upon the designation of any Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture, such Subsidiary Guarantor will be released and relieved of any obligations under its Subsidiary Guarantee; and in each such case, prior to release and discharge or such Guarantee, Arch Western will have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to such transactions have been complied with and that such release is authorized and permitted hereunder. The Trustee shall execute any documents reasonably requested by either Arch Western or a Subsidiary Guarantor in order to evidence the release of such Subsidiary Guarantor from its obligations under its Subsidiary Guarantee endorsed on the Notes and under this Article Ten. SECTION 10.04. Additional Guarantors. Arch Western covenants and agrees that it shall cause any Person which becomes obligated to Guarantee the Notes, pursuant to the terms of Section 4.13, to execute a supplemental indenture and any other documentation requested by the Trustee satisfactory in form and substance to the Trustee in accordance with Section 4.13 pursuant to which such Restricted Subsidiary shall Guarantee the obligations of Arch Western under the Notes and this Indenture in accordance with this Article Ten with the same effect and to the same extent as if such Person had been named herein as a Subsidiary Guarantor. SECTION 10.05. Limitation of Guarantee. The Guarantee is limited in an amount not to exceed the maximum amount that can be guaranteed by the Guarantor without rendering such Guarantee, as it relates to the Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer of similar laws affecting the rights of the creditors generally. SECTION 10.06. Notation Not Required. Neither the Issuer nor the Guarantor shall be required to make a notation on the Notes to reflect any Guarantee or any release, termination or discharge thereof. 87 SECTION 10.07. Successors and Assigns. This Article Ten shall be binding upon the Guarantor and each of their successors and assigns and shall inure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Notes shall automatically extend to and be vested in such transferee or assigns, all subject to the terms and conditions of this Indenture. SECTION 10.08. No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article Ten shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and are not exclusive of any other rights, remedies or benefits which either may have under this Article Ten at law, in equity, by statute or otherwise. SECTION 10.09. Modification. No modification, amendment or waiver of any provision of this Article Ten, nor the consent to any departure by the Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on the Guarantor in any case shall entitle the Guarantor to any other or further notice or demand in the same, similar or other circumstance. ARTICLE ELEVEN SECURITY DOCUMENTS SECTION 11.01. Security Documents.

Arch Western shall take, and shall cause the Issuer and the Subsidiary Guarantors to take, any and all actions reasonably required to cause the Security Documents to create and maintain, as security for the obligations of the Issuer and the Guarantors hereunder, (x) a valid and 88 enforceable Lien on and security interest in all the Collateral in favor of the Trustee for the benefit of itself and of the Holders, and (y) such Lien as a perfected Lien. Each of Arch Western and the Subsidiary Guarantors covenants and agrees that it shall execute, acknowledge and deliver to the Trustee (and, if the Trustee is not the Collateral Trustee, the Collateral Trustee) such further assignments, transfers, assurances or other instruments and shall do or cause to be done all such acts and things as may be necessary or proper to assure and confirm to the Trustee (and, if the Trustee is not the Collateral Trustee, the Collateral Trustee) its interest in the Collateral, or any part thereof, as from time to time constituted, and the right, title and interest in and to the Security Documents so as to render the same available for the security and benefit of this Indenture and of the Notes.

The Issuer and the Guarantors shall from time to time promptly pay all financing, continuation statement and mortgage recording, registration and/or filing fees, charges and taxes relating to this Indenture and the Security Documents, any amendments thereto and any other instruments of further assurance required hereunder or pursuant to the Security Documents.

SECTION 11.03. Release of Collateral. (a) Collateral may (and, as applicable, shall) be released or substituted only in accordance with the terms of the Security Documents.

Subject to the provisions of Sections 7.01 and 7.02, the Trustee (and, if the Trustee is not the Collateral Trustee, the Collateral Trustee) may, in its sole discretion and without the consent of the Holders, on behalf of the Trustee and the Holders, take all actions it deems necessary or appropriate, and, if the Trustee is not the Collateral Trustee, the Trustee may, in its sole discretion and without the consent of the Holders, direct, on behalf of 89 itself and the Holders, the Collateral Trustee to take all actions it deems necessary or appropriate, in order to, (a) enforce any of the terms of the Security Documents and (b) collect and receive any and all amounts payable in respect of the Obligations (as defined in the Note Pledge Agreement).

Beyond the exercise of reasonable care in the custody thereof, the Trustee shall have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and the Trustee shall not be responsible for recording or filing or re-recording or re-filing any mortgage or financing or continuation statements or recording or re-recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any Lien or security interest in any of the Collateral. The Trustee shall be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property and shall not be liable or responsible for any loss or diminution in the value of any of the Collateral by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Trustee in good faith. The Trustee makes no representations as to and shall not be responsible for the existence, genuineness, value or condition of any of the Collateral or as to the security afforded or intended to be afforded thereby, hereby or by any security agreement, or for the validity, perfection, priority or enforceability of the Liens or security interests in any of the Collateral created or 90 intended to be created by any of the security agreements, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, except to the extent such action or omission constitutes gross negligence or willful misconduct on the part of the Trustee, for the validity or sufficiency of the Collateral, any security agreement or any agreement or assignment contained in any thereof, for the validity of the title of the Issuer or any of the Subsidiaries to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral.

However, without the consent of the Holder of each outstanding Note affected thereby, an amendment may not: (a) reduce the amount of Notes whose Holders must consent to an amendment or waiver, (b) reduce the rate of, or extend the time for payment of, interest on any Note, (c) reduce the principal of, or extend the Stated Maturity of, any Note, (d) make any Note payable in money other than that stated in the Note, (e) impair the right of any Holder to receive payment of principal of, premium, if any, and interest, on, such holder's Notes on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder's Notes, A-9 (f) release any security interest that may have been granted in favor of the Holders other than pursuant to the terms of such security interest, (g) reduce the premium payable upon the redemption of any Note or change the time at which any Note may be redeemed, pursuant to Section 3.01 of the Indenture (h) reduce the premium payable upon a Change of Control or, at any time after a Change of Control has occurred, change the time at which the Change of Control Offer relating thereto must be made or at which the Notes must be repurchased pursuant to such Change of Control Offer, (i) at any time after the Issuer is obligated to make a Prepayment Offer with the Excess Proceeds from Asset Sales, change the time at which such Prepayment Offer must be made or at which the Notes must be repurchased pursuant thereto, (j) modify or change any provision of the Indenture affecting the ranking of the Notes or the Note Guarantees in a manner adverse to the Holders (it being understood that amendments or waivers of Security Documents or releases of Liens on the Arch Coal Notes do not relate to ranking), or (k) release any Guarantor from any of its obligations under its Note Guarantee or the Indenture other than in accordance with the provisions of the Indenture, or amend or modify any provision relating to such release. The consent of the Holders is not necessary under the Indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment. Notwithstanding the foregoing, without notice to or the consent of any Holder of the Notes, the Issuer, the Guarantors and the Trustee may, among other things, modify, amend or supplement the Indenture: (a) cure any ambiguity, omission, defect or inconsistency in any manner that is not adverse in any material respect to any holder of the Notes, (b) provide for the assumption by a Surviving Person of the obligations of Arch Western under the Indenture, (c) provide for uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code), (d) add Note Guarantees with respect to the Notes or confirm and evidence the release, termination or discharge of any security or Note Guarantee when such release, termination or discharge is permitted by the Indenture, A-10 (e) secure the Notes, add to the covenants of the Issuer for the benefit of the Holders or surrender any right or power conferred upon the Issuer, (f) make any change that does not adversely affect the rights of any holder of the Notes, (g) comply with any requirement of the Commission in connection with the qualification of this Indenture under the Trust Indenture Act, or (h) provide for the issuance of Additional Notes in accordance with the Indenture. After an amendment becomes effective in accordance with the above position, the Issuer shall mail to each Holder at such Holder's address appearing in the Security Register a notice briefly describing such amendment. However, the failure to give such notice to all Holders, or any defect therein, will not impair or affect the validity of the amendment. 13. Defaults and Remedies The Notes have the Events of Default as set forth in Section 6.01 of the Indenture. If an Event of Default occurs and is continuing, the Trustee, by notice to the Issuer, or the registered Holders of not less than 25% in aggregate principal amount of the Notes then outstanding by notice to the Issuer and the Trustee, subject to certain limitations, may declare all the Notes to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default and shall result in the Notes being due and payable immediately upon the occurrence of such Events of Default. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes unless it receives an indemnity satisfactory to it. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Notes may direct the Trustee in its exercise of any trust or power. The Holders of a majority in aggregate principal amount of the Notes then outstanding by written notice to the Trustee may rescind any acceleration and its consequence if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal, premium, if any, or interest that has become due solely because of such acceleration. The above description of Events of Default and remedies is qualified by reference, and subject in its entirety, to the more complete description thereof contained in the Indenture. 14. Trustee Dealings with the Issuer Subject to certain limitations imposed by the Trust Indenture Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Issuer, the Guarantor or any of their Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, co-Registrar or co-Paying Agent may do the same with like rights. 15. No Recourse Against Others A-11 A director, officer, employee, or stockholder, as such, of the Issuer or the Guarantor shall not have any liability for any obligations of the Issuer or the Guarantor under the Notes, the Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. By accepting a Note, each Holder shall waive and release all such liability. The waiver and release are part of the consideration for the issue of the Notes. 16. Authentication This Note shall not be valid until an authorized officer of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Note. 17. Governing Law THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

                           (iii)    use their reasonable best efforts to keep
         the Exchange Offer Registration Statement continuously effective under
         the Act, supplemented and amended as required, under the Act to ensure

         including a representation that each of the Issuer and the Guarantors
         has not entered into any arrangement or understanding with any Person

         Exchange Offer and that, to the best of each of the Issuer's and the
         Guarantors' information and belief, each Holder participating in the
         Registered Exchange Offer is acquiring the New Securities in the
         ordinary course of business and has no arrangement or understanding

         accordance with Section 4(s) all Securities so accepted for exchange;
         and

                            (iii)   cause the New Securities Trustee promptly to

                                        5



                  (e)      Each Holder hereby acknowledges and agrees that any
Broker-Dealer and any such Holder using the Registered Exchange Offer to
participate in a distribution of the New Securities (x) could not under
Commission policy as in effect on the date of this Agreement rely on the
position of the Commission in Morgan Stanley and Co., Inc. (pub. avail. June 5,
1991) and Exxon Capital Holdings Corporation (pub. avail. May 13, 1988), as
interpreted in the Commission's letter to Shearman & Sterling dated July 2, 1993
and similar no-action letters; and (y) must comply with the registration and
prospectus delivery requirements of the Act in connection with any secondary
resale transaction must be covered by an effective registration statement
containing the selling security holder information required by Item 507 or 508,
as applicable, of Regulation S-K under the Act if the resales are of New
Securities obtained by such Holder in exchange for Securities acquired by such
Holder directly from the Company or one of its Affiliates. Accordingly, each
Holder participating in the Registered Exchange Offer shall be required to
represent to the Issuer and the Guarantors that, at the time of the consummation
of the Registered Exchange Offer:

                           (i)      any New Securities received by such Holder
         will be acquired in the ordinary course of business;

                           (ii)     such Holder will have no arrangement or
         understanding with any Person to participate in the distribution of the
         Securities or the New Securities within the meaning of the Act; and

                           (iii)    such Holder is not an Affiliate of the
         Issuer or any Guarantor.

                  (f)      If any Initial Purchaser determines that it is not
eligible to participate in the Registered Exchange Offer with respect to the
exchange of Securities constituting any portion of an unsold allotment, at the
request of such Initial Purchaser, the Issuer, the Company and the Guarantors
shall issue and deliver to such Initial Purchaser or the Person purchasing New
Securities registered under a Shelf Registration Statement as contemplated by
Section 3 hereof from such Initial Purchaser, in exchange for such Securities, a
like principal amount of New Securities. The Issuer, the Company and the
Guarantors shall use their reasonable best efforts to cause the CUSIP Service
Bureau to issue the same CUSIP number for such New Securities as for New
Securities issued pursuant to the Registered Exchange Offer.

                  3.       Shelf Registration. (a) If (i) due to any change in
law or applicable interpretations thereof by the Commission's staff, the Issuer,
the Company and the Guarantors determines upon advice of their outside counsel
that they are not permitted to effect the Registered Exchange Offer as
contemplated by Section 2 hereof; (ii) for any other reason the Registered
Exchange Offer is not consummated within 225 days of the date hereof; (iii) any
Initial Purchaser so requests with respect to Securities that are not eligible
to be exchanged for New Securities in the Registered Exchange Offer and that are
held by it following consummation of the Registered Exchange Offer; (iv) any
Holder (other than an Initial Purchaser) is not eligible to participate in the
Registered Exchange Offer; or (v) in the case of any Initial Purchaser that
participates in the Registered Exchange Offer or acquires New Securities
pursuant to Section 2(f) hereof, such Initial Purchaser does not receive freely
tradeable New Securities in exchange for Securities constituting any portion of
an unsold allotment (it being understood that (x) the requirement that an
Initial Purchaser deliver a Prospectus containing the information required by

                                        6



Item 507 or 508 of Regulation S-K under the Act in connection with sales of New
Securities acquired in exchange for such Securities shall result in such New
Securities being not "freely tradeable"; and (y) the requirement that an
Exchanging Dealer deliver a Prospectus in connection with sales of New
Securities acquired in the Registered Exchange Offer in exchange for Securities
acquired as a result of market-making activities or other trading activities
shall not result in such New Securities being not "freely tradeable"), the
Issuer, the Company and the Guarantors shall effect a Shelf Registration
Statement in accordance with subsection (b) below.

                  (b)      (i) The Issuer and the Guarantors shall as promptly
as practicable (but in no event more than 60 days after so required or requested
pursuant to this Section 3), file with the Commission and thereafter the Issuer,
the Company and the Guarantors shall use their reasonable best efforts to cause
to be declared effective under the Act a Shelf Registration Statement relating
to the offer and sale of the Securities or the New Securities, as applicable, by
the Holders thereof from time to time in accordance with the methods of
distribution elected by such Holders and set forth in such Shelf Registration
Statement; provided, however, that no Holder (other than an Initial Purchaser)
shall be entitled to have the Securities held by it covered by such Shelf
Registration Statement unless such Holder agrees in writing to be bound by all
of the provisions of this Agreement applicable to such Holder; and provided
further, that with respect to New Securities received by an Initial Purchaser in
exchange for Securities constituting any portion of an unsold allotment, the
Issuer and the Guarantors may, if permitted by current interpretations by the
Commission's staff, file a post-effective amendment to the Exchange Offer
Registration Statement containing the information required by Item 507 or 508 of
Regulation S-K, as applicable, in satisfaction of their obligations under this
subsection with respect thereto, and any such Exchange Offer Registration
Statement, as so amended, shall be referred to herein as, and governed by the
provisions herein applicable to, a Shelf Registration Statement.

                           (ii)     The Issuer, the Company and the Guarantors
         shall use their reasonable best efforts to keep the Shelf Registration
         Statement continuously effective, supplemented and amended as required
         by the Act, in order to permit the Prospectus forming part thereof to
         be usable by Holders for a period of two years from the date the Shelf
         Registration Statement is declared effective by the Commission or such
         shorter period that will terminate when all the Securities or New
         Securities, as applicable, covered by the Shelf Registration Statement
         have been sold pursuant to the Shelf Registration Statement (in any
         such case, such period being called the "Shelf Registration Period").
         Each of the Issuer, the Company and the Guarantors shall be deemed not
         to have used its reasonable best efforts to keep the Shelf Registration
         Statement effective during the requisite period if it voluntarily takes
         any action that would result in Holders of Securities covered thereby
         not being able to offer and sell such Securities during that period,
         unless (A) such action is required by applicable law; or (B) such
         action is taken by the Issuer, the Company and the Guarantors in good
         faith and for valid business reasons (not including avoidance of the
         Issuer's, the Company's and Guarantors' obligations hereunder),
         including the acquisition or divestiture of assets, so long as each of
         the Issuer, the Company and the Guarantors promptly thereafter complies
         with the requirements of Section 4(k) hereof, if applicable.

                           (iii)    The Issuer, the Company and the Guarantors
         shall cause the Shelf Registration Statement and the related Prospectus
         and any amendment or supplement

                                        7



         thereto, as of the effective date of the Shelf Registration Statement
         or such amendment or supplement, (A) to comply in all material respects
         with the applicable requirements of the Securities Act and the rules
         and regulations of the Commission; and (B) not to contain any untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary in order to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading.

                  4.       Additional Registration Procedures. In connection
with any Shelf Registration Statement and, to the extent applicable, any
Exchange Offer Registration Statement, the following provisions shall apply.

         amendment or supplement, if any, to the Prospectus included therein
         (including all documents incorporated by reference therein after the
         initial filing) and shall use their best efforts to reflect in each
         such document, when so filed with the Commission, such comments as you
         reasonably propose;

                           (ii)     include the information set forth in Annex A
         hereto on the facing page of the Exchange Offer Registration Statement,
         in Annex B hereto in the forepart of the Exchange Offer Registration

         include the information required by Item 507 or 508 of Regulation S-K,
         as applicable, in the Prospectus contained in the Exchange Offer
         Registration Statement; and

         Statement, include the names of the Holders that propose to sell
         Securities pursuant to the Shelf Registration Statement as selling
         security holders.

                  (b)      The Issuer, the Company and the Guarantors shall
ensure that:

                           (i)      any Registration Statement and any amendment
         thereto and any Prospectus forming part thereof and any amendment or
         supplement thereto complies in all material respects with the Act and
         the rules and regulations thereunder; and

                           (ii)     any Registration Statement and any amendment
         thereto does not, when it becomes effective, contain an untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary to make the statements therein not
         misleading.

                  (c)      The Company shall advise you, the Holders of
Securities covered by any Shelf Registration Statement and any Exchanging Dealer

facsimile number and address for notices, and, if requested by you or any such
Holder or Exchanging Dealer, shall confirm such advice in writing (which notice
pursuant to clauses (ii)-(v) hereof shall be accompanied by an instruction to
suspend the use of the Prospectus until the Issuer and the Guarantors shall have
remedied the basis for such suspension):

                           (i)      when a Registration Statement and any
         amendment thereto has been filed with the Commission and when the
         Registration Statement or any post-effective amendment thereto has
         become effective;

                           (ii)     of any request by the Commission for any
         amendment or supplement to the Registration Statement or the Prospectus
         or for additional information;

                           (iii)    of the issuance by the Commission of any
         stop order suspending the effectiveness of the Registration Statement
         or the initiation of any proceedings for that purpose;

                           (iv)     of the receipt by the Issuer, the Company or
         any Guarantor of any notification with respect to the suspension of the
         qualification of the securities included therein for sale in any
         jurisdiction or the initiation of any proceeding for such purpose; and

                           (v)      of the happening of any event that requires
         any change in the Registration Statement or the Prospectus so that, as
         of such date, the statements therein are not misleading and do not omit
         to state a material fact required to be stated therein or necessary to
         make the statements therein (in the case of the Prospectus, in the
         light of the circumstances under which they were made) not misleading.

                  (d)      The Issuer, the Company and the Guarantors shall use
their reasonable best efforts to obtain the withdrawal of any order suspending
the effectiveness of any Registration Statement or the qualification of the

during the Shelf Registration Period, deliver to each Holder of Securities
covered by any Shelf Registration Statement, without charge, as many copies of
the Prospectus (including each preliminary Prospectus) included in such Shelf
Registration Statement and any amendment or supplement thereto as such Holder
may reasonably request. Each of the Issuer and the Guarantors consents to the
use of the Prospectus or any amendment or supplement thereto by each of the
selling Holders of securities in connection with the offering and sale of the
securities covered by the Prospectus, or any amendment or supplement thereto,
included in the Shelf Registration Statement.

furnish to each Exchanging Dealer which so requests, without charge, at least
one copy of the Exchange Offer Registration Statement and any post-effective
amendment thereto, including all material incorporated by reference therein,
and, if the Exchanging Dealer so requests in writing, all exhibits thereto
(including exhibits incorporated by reference therein).

                  (h)      The Issuer, the Company and the Guarantors shall
promptly deliver to each Initial Purchaser, each Exchanging Dealer and each
other Person required to deliver a Prospectus during the Exchange Offer
Registration Period, without charge, as many copies of the Prospectus included
in such Exchange Offer Registration Statement and any amendment or supplement
thereto as any such Person may reasonably request. Each of the Issuer, the
Company and the Guarantors consents to the use of the Prospectus or any
amendment or supplement thereto by any Initial Purchaser, any Exchanging Dealer
and any such other Person that may be required to deliver a Prospectus following
the Registered Exchange Offer in connection with the offering and sale of the
New Securities covered by the Prospectus, or any amendment or supplement
thereto, included in the Exchange Offer Registration Statement.

                  (i)      Prior to the Registered Exchange Offer or any other
offering of Securities pursuant to any Registration Statement, the Issuer, the
Company and the Guarantors shall use their reasonable best efforts to arrange,
if necessary, for the qualification of the Securities or the New Securities for
sale under the laws of such jurisdictions as any Holder shall reasonably request
and will maintain such qualification in effect so long as required to enable the
offer and sale in such jurisdictions of the Securities or New Securities;
provided that in no event shall the Issuer, the Company or the Guarantors be
obligated to qualify to do business in any jurisdiction where they are not then
so qualified or to take any action that would subject them to service of process
in suits, other than those arising out of the Initial Placement, the Registered
Exchange Offer or any offering pursuant to a Shelf Registration Statement, in
any such jurisdiction where they are not then so subject.

                  (j)      The Issuer, the Company and the Guarantors shall
cooperate with the Holders of Securities to facilitate the timely preparation
and delivery of certificates representing New Securities or Securities to be
issued or sold pursuant to any Registration Statement free of any restrictive
legends and in such denominations and registered in such names as Holders may
request.

                  (k)      Upon the occurrence of any event contemplated by
subsections (c)(ii) through (v) above during the period for which the Issuer,
the Company and the Guarantors are required under this Agreement to maintain an
effective Registration Statement. The Issuer, the Company and the Guarantors
shall promptly prepare a post-effective amendment to the applicable Registration
Statement or an amendment or supplement to the related Prospectus or file any
other required document so that, as thereafter delivered to Initial Purchasers
of the securities included therein, the Prospectus will not include an untrue
statement of a material fact or omit to state any material fact necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading. In such circumstances, the period of effectiveness of
the Exchange Offer Registration Statement provided for in Section 2 and the
Shelf Registration Statement provided for in Section 3(b) shall each be extended
by the number of days from and including the date of the giving of a notice of
suspension pursuant to Section

4(c) to and including the date when the Initial Purchasers, the Holders of the
Securities and any known Exchanging Dealer shall have received such amended or
supplemented Prospectus pursuant to this Section.

                  (l)      Not later than the effective date of any Registration
Statement, the Issuer, the Company and the Guarantors shall provide a CUSIP
number for the Securities or the New Securities, as the case may be, registered
under such Registration Statement and provide the Trustee with printed
certificates for such Securities or New Securities, in a form eligible for
deposit with The Depository Trust Company.

                  (m)      The Issuer, the Company and the Guarantors shall
comply with all applicable rules and regulations of the Commission and shall
make generally available to their security holders as soon as practicable after
the effective date of the applicable Registration Statement an earnings
statement satisfying the provisions of Section 11(a) of the Act.

                  (n)      The Issuer and the Guarantors shall cause the
Indenture or the New Securities Indenture, as the case may be, to be qualified
under the Trust Indenture Act, as required by applicable law, in a timely
manner.

                  (o)      The Issuer and the Guarantors may require each Holder
of securities to be sold pursuant to any Shelf Registration Statement to furnish
to the Issuer and the Guarantors such information regarding the Holder and the
distribution of such securities as the Issuer and the Guarantors may from time
to time reasonably require for inclusion in such Registration Statement. The
Issuer and the Guarantors may exclude from such Shelf Registration Statement the
Securities of any Holder that fails to furnish such information within a
reasonable time after receiving such request.

                  (p)      In the case of any Shelf Registration Statement, the
Issuer, the Company and the Guarantors shall enter into such and take all other
appropriate actions (including if requested an underwriting agreement in
customary form) in order to expedite or facilitate the registration or the
disposition of the Securities, and in connection therewith, if an underwriting
agreement is entered into, cause the same to contain indemnification provisions
and procedures no less favorable than those set forth in Section 6 (or such
other provisions and procedures acceptable to the Majority Holders and the
Managing Underwriters, if any, with respect to all parties to be indemnified
pursuant to Section 6.

                  (q)      In the case of any Shelf Registration Statement, each
of the Issuer, the Company and the Guarantors shall:

                           (i)      make reasonably available for inspection by
         the Holders of Securities to be registered thereunder, any underwriter
         participating in any disposition pursuant to such Registration
         Statement, and any attorney, accountant or other agent retained by the
         Holders or any such underwriter all relevant financial and other
         records, pertinent corporate documents and properties of the Company
         and its subsidiaries;

                           (ii)     cause the Company's and Arch Western's
         respective officers, directors and employees to supply all relevant
         information reasonably requested by the Holders or any such
         underwriter, attorney, accountant or agent in connection with any

                                       11



         such Registration Statement as is customary for similar due diligence
         examinations; provided, however, that any information that is
         designated in writing by the Company or Arch Western, in good faith, as
         confidential at the time of delivery of such information shall be kept
         confidential by the Holders or any such underwriter, attorney,
         accountant or agent, unless such disclosure is made in connection with
         a court proceeding or required by law, or such information becomes
         available to the public generally or through a third party without an
         accompanying obligation of confidentiality;

                           (iii)    make such representations and warranties to
         the Holders of Securities registered thereunder and the underwriters,
         if any, in form, substance and scope as are customarily made by issuers
         to underwriters in primary underwritten offerings and covering matters
         including, but not limited to, those set forth in the Purchase
         Agreement;

                           (iv)     obtain opinions of counsel to the Issuer,
         the Company and the Guarantors and updates thereof (which counsel and
         opinions (in form, scope and substance) shall be reasonably
         satisfactory to the Managing Underwriters, if any) addressed to each
         selling Holder and the underwriters, if any, covering such matters as
         are customarily covered in opinions requested in underwritten offerings
         and such other matters as may be reasonably requested by such Holders
         and underwriters;

                           (v)      obtain "cold comfort" letters and updates
         thereof from the independent certified public accountants of the
         Company, Arch Western and Canyon Fuel Company, LLC (and, if necessary,
         any other independent certified public accountants of any subsidiary of
         the Company or of any business acquired by the Company for which
         financial statements and financial data are, or are required to be,
         included in the Registration Statement), addressed to each selling
         Holder of Securities registered thereunder and the underwriters, if

         may be reasonably requested by the Majority Holders and the Managing
         Underwriters, if any, including those to evidence compliance with
         Section 4(k) and with any customary conditions contained in the
         underwriting agreement or other agreement entered into by the Issuer,
         the Company and the Guarantors.

The actions set forth in clauses (iii), (iv), (v) and (vi) of this Section shall
be performed at (A) the effectiveness of such Registration Statement and each
post-effective amendment thereto; and (B) each closing under any underwriting or
similar agreement as and to the extent required thereunder.

                  (r)      In the case of any Exchange Offer Registration
Statement, each of the Issuer, the Company and the Guarantors shall, for any
Initial Purchaser which is exchanging Securities for New Securities in the

                                       12



                           (i)      make reasonably available for inspection by
         such Initial Purchaser, and any attorney, accountant or other agent
         retained by such Initial Purchaser, all relevant financial and other
         records, pertinent corporate documents and properties of the Company,

         respective officers, directors and employees to supply all relevant
         information reasonably requested by such Initial Purchaser or any such
         attorney, accountant or agent in connection with any such Registration
         Statement as is customary for similar due diligence examinations;
         provided, however, that any information that is designated in writing
         by the Company and Arch Western, in good faith, as confidential at the
         time of delivery of such information shall be kept confidential by such
         Initial Purchaser or any such attorney, accountant or agent, unless
         such disclosure is made in connection with a court proceeding or
         required by law, or such information becomes available to the public
         generally or through a third party without an accompanying obligation
         of confidentiality;

                           (iii)    make such representations and warranties to
         such Initial Purchaser, in form, substance and scope as are customarily
         made by issuers to underwriters in primary underwritten offerings and
         covering matters including, but not limited to, those set forth in the
         Purchase Agreement;

                           (iv)     obtain opinions of counsel to the Issuer,
         the Company and the Guarantors and updates thereof (which counsel and
         opinions (in form, scope and substance) shall be reasonably
         satisfactory to such Initial Purchaser and its counsel, addressed to
         such Initial Purchaser, covering such matters as are customarily

         matters as may be reasonably requested by such Initial Purchaser or its
         counsel;

                           (v)      obtain "cold comfort" letters and updates
         thereof from the independent certified public accountants of the
         Company, Arch Western and Canyon Fuel Company, LLC (and, if necessary,
         any other independent certified public accountants of any subsidiary of
         the Company or of any business acquired by the Company for which
         financial statements and financial data are, or are required to be,
         included in the Registration Statement), addressed to such Initial
         Purchaser, in customary form and covering matters of the type
         customarily covered in "cold comfort" letters in connection with
         primary underwritten offerings, or if requested by such Initial
         Purchaser or its counsel in lieu of a "cold comfort" letter, an
         agreed-upon procedures letter under Statement on Auditing Standards No.
         35, covering matters requested by such Initial Purchaser or its
         counsel; and

                           (vi)     deliver such documents and certificates as
         may be reasonably requested by such Initial Purchaser or its counsel,
         including those to evidence compliance with Section 4(k) and with
         conditions customarily contained in underwriting agreements.

The foregoing actions set forth in clauses (iii), (iv), (v), and (vi) of this
Section shall be performed at the close of the Registered Exchange Offer and the
effective date of any post-effective amendment to the Exchange Offer
Registration Statement.

                                       13



                  (s)      If a Registered Exchange Offer is to be consummated,
upon delivery of the Securities by Holders to the Issuer and the Guarantors (or
to such other Person as directed by the Issuer and the Guarantors) in exchange
for the New Securities, the Issuer and the Guarantors shall mark, or caused to
be marked, on the Securities so exchanged that such Securities are being
canceled in exchange for the New Securities. In no event shall the Securities be
marked as paid or otherwise satisfied.

                  (t)      The Issuer, the Company and the Guarantors shall use
their best efforts (i) if the Securities have been rated prior to the initial
sale of such Securities, to confirm such ratings will apply to the Securities or
the New Securities, as the case may be, covered by a Registration Statement; or
(ii) if the Securities were not previously rated, to cause the Securities
covered by a Registration Statement to be rated with at least one nationally
recognized statistical rating agency, if so requested by Majority Holders with
respect to the related Registration Statement or by any Managing Underwriters.

                  (u)      In the event that any Broker-Dealer shall underwrite
any Securities or participate as a member of an underwriting syndicate or
selling group or "assist in the distribution" (within the meaning of the Rules
of Fair Practice and the By-Laws of the National Association of Securities
Dealers, Inc.) thereof, whether as a Holder of such Securities or as an
underwriter, a placement or sales agent or a broker or dealer in respect
thereof, or otherwise, assist such Broker-Dealer in complying with the
requirements of such Rules and By-Laws, including, without limitation, by:

                           (i)      if such Rules or By-Laws shall so require,
         engaging a "qualified independent underwriter" (as defined in such
         Rules) to participate in the preparation of the Registration Statement,
         to exercise usual standards of due diligence with respect thereto and,
         if any portion of the offering contemplated by such Registration
         Statement is an underwritten offering or is made through a placement or
         sales agent, to recommend the yield of such Securities;

                           (ii)     indemnifying any such qualified independent
         underwriter to the extent of the indemnification of underwriters
         provided in Section 6 hereof; and

                           (iii)    providing such information to such
         Broker-Dealer as may be required in order for such Broker-Dealer to
         comply with the requirements of such Rules.

                           (iv)     The Issuer, the Company and the Guarantors
         shall use their best efforts to take all other steps necessary to
         effect the registration of the Securities or the New Securities, as the
         case may be, covered by a Registration Statement.

                  5.       Registration Expenses. The Issuer, the Company and
the Guarantors shall bear all expenses incurred in connection with the
performance of their obligations under Sections 2, 3 and 4 hereof and, in the
event of any Shelf Registration Statement, will reimburse the Holders for the
reasonable fees and disbursements of one firm or counsel designated by the
Majority Holders to act as counsel for the Holders in connection therewith, and,
in the case of any Exchange Offer Registration Statement, will reimburse the
Initial Purchasers for the reasonable fees and disbursements of counsel acting
in connection therewith.

                                       14



                  6.       Indemnification and Contribution. (a) Each of the
Issuer, the Company and the Guarantors agrees, jointly and severally, to
indemnify and hold harmless each Holder of Securities or New Securities, as the
case may be, covered by any Registration Statement (including each Initial
Purchaser and, with respect to any Prospectus delivery as contemplated in
Section 4(h) hereof, each Exchanging Dealer), the directors, officers, employees
and agents of each such Holder and each Person who controls any such Holder
within the meaning of either the Act or the Exchange Act against any and all
losses, claims, damages or liabilities, joint or several, to which they or any
of them may become subject under the Act, the Exchange Act or other Federal or
state statutory law or regulation, at common law or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement as originally filed or in
any amendment thereof, or in any preliminary Prospectus or the Prospectus, or in
any amendment thereof or supplement thereto, or arise out of or are based upon
the omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
agrees to reimburse each such indemnified party, as incurred, for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the Issuer, the Company and the Guarantors will not be liable in any case
to the extent that any such loss, claim, damage or liability arises out of or is
based upon any such untrue statement or alleged untrue statement or omission or
alleged omission made therein in reliance upon and in conformity with written
information furnished to the Issuer, the Company and the Guarantors by or on
behalf of any such Holder specifically for inclusion therein. This indemnity
agreement will be in addition to any liability which the Issuer, the Company and
the Guarantors may otherwise have.

                  Each of the Issuer, the Company and the Guarantors also agrees
to indemnify or contribute as provided in Section 6(d) to Losses of each any
underwriter of Securities or New Securities, as the case may be, registered
under a Shelf Registration Statement, their directors, officers, employees or
agents and each Person who controls such underwriter on substantially the same
basis as that of the indemnification of the Initial Purchasers and the selling
Holders provided in this Section 6(a) and shall, if requested by any Holder,
enter into an underwriting agreement reflecting such agreement, as provided in
Section 4(p) hereof.

                  (b)      Each Holder of securities covered by a Registration
Statement (including each Initial Purchaser and, with respect to any Prospectus
delivery as contemplated in Section 4(h) hereof, each Exchanging Dealer)
severally agrees to indemnify and hold harmless each of the Issuer, the Company
and the Guarantors, each of its directors, each of its officers who signs such
Registration Statement and each Person who controls the Issuer, the Company or
any Guarantor within the meaning of either the Act or the Exchange Act, to the
same extent as the foregoing indemnity from each of the Issuer, the Company and
the Guarantors to each such Holder, but only with reference to written
information relating to such Holder furnished to the Issuer, the Company and the
Guarantors by or on behalf of such Holder specifically for inclusion in the
documents referred to in the foregoing indemnity. This indemnity agreement will
be in addition to any liability which any such Holder may otherwise have.

                  (c)      Promptly after receipt by an indemnified party under
this Section 6 or notice of the commencement of any action, such indemnified
party will, if a claim in respect

                                       15



thereof is to be made against the indemnifying party under this Section, notify
the indemnifying party in writing of the commencement thereof; but the failure
so to notify the indemnifying party (i) will not relieve it from liability under
paragraph (a) or (b) above unless and to the extent it did not otherwise learn
of such action and such failure results in the forfeiture by the indemnifying
party of substantial rights and defenses; and (ii) will not, in any event,
relieve the indemnifying party from any obligations to any indemnified party
other than the indemnification obligation provided in paragraph (a) or (b)
above. The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent the
indemnified party in any action for which indemnification is sought (in which
case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties
except as set forth below); provided, however, that such counsel shall be
satisfactory to the indemnified party. Notwithstanding the indemnifying party's
election to appoint counsel to represent the indemnified party in an action, the
indemnified party shall have the right to employ separate counsel (including
local counsel), and the indemnifying party shall bear the reasonable fees, costs
and expenses of such separate counsel if (i) the use of counsel chosen by the
indemnifying party to represent the indemnified party would present such counsel
with a conflict of interest; (ii) the actual or potential defendants in, or
targets of, any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
indemnifying party; (iii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of the institution of such action; or (iv) the
indemnifying party shall authorize the indemnified party to employ separate
counsel at the expense of the indemnifying party. An indemnifying party will
not, without the prior written consent of the indemnified parties, settle or
compromise or consent to the entry of any judgment with respect to any pending
or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim, action,
suit or proceeding.

                  (d)      In the event that the indemnity provided in paragraph
(a) or (b) of this Section is unavailable to or insufficient to hold harmless an
indemnified party for any reason, then each applicable indemnifying party shall
have a joint and several obligation to contribute to the aggregate losses,
claims, damages and liabilities (including legal or other expenses reasonably
incurred in connection with investigating or defending same) (collectively
"Losses") to which such indemnified party may be subject in such proportion as
is appropriate to reflect the relative benefits received by such indemnifying
party, on the one hand, and such indemnified party, on the other hand, from the
Initial Placement and the Registration Statement which resulted in such Losses;
provided, however, that in no case shall any Initial Purchaser or any subsequent
Holder of any Security or New Security be responsible, in the aggregate, for any
amount in excess of the purchase discount or commission applicable to such
Security, or in the case of a New Security, applicable to the Security that was
exchangeable into such New Security, as set forth on the cover page of the Final
Memorandum, nor shall any underwriter be responsible for any amount in excess of
the underwriting discount or commission applicable to the securities purchased
by such underwriter under the Registration Statement which resulted in such
Losses. If the allocation provided by the immediately preceding sentence is
unavailable for

                                       16



any reason, the indemnifying party and the indemnified party shall contribute in
such proportion as is appropriate to reflect not only such relative benefits but
also the relative fault of such indemnifying party, on the one hand, and such
indemnified party, on the other hand, in connection with the statements or
omissions which resulted in such Losses as well as any other relevant equitable
considerations. Benefits received by each of the Issuer, the Company and the
Guarantors shall be deemed to be equal to the sum of (x) the total net proceeds
from the Initial Placement (before deducting expenses) and (y) the total amount
of additional interest which the Issuer and the Guarantors were not required to
pay as a result of registering the securities covered by the Registration
Statement which resulted in such Losses. Benefits received by the Initial
Purchasers shall be deemed to be equal to the total purchase discounts and
commissions from the Initial Placement, and benefits received by any other
Holders shall be deemed to be equal to the value of receiving Securities or New
Securities, as applicable, registered under the Act. Benefits received by any
underwriter shall be deemed to be equal to the total underwriting discounts and
commissions, as set forth on the cover page of the Prospectus forming a part of
the Registration Statement which resulted in such Losses. Relative fault shall
be determined by reference to, among other things, whether any alleged untrue
statement or omission relates to information provided by the indemnifying party,
on the one hand, or by the indemnified party, on the other hand, the intent of
the parties and their relative knowledge, access to information and opportunity
to correct or prevent such untrue statement or omission. The parties agree that
it would not be just and equitable if contribution were determined by pro rata
allocation (even if the Holders were treated as one entity for such purpose) or
any other method of allocation which does not take account of the equitable
considerations referred to above. Notwithstanding the provisions of this
paragraph (d), no Person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
Person who was not guilty of such fraudulent misrepresentation. For purposes of
this Section, each Person who controls a Holder within the meaning of either the
Act or the Exchange Act and each director, officer, employee and agent of such
Holder shall have the same rights to contribution as such Holder, and each
Person who controls the Issuer, the Company or any Guarantor within the meaning
of either the Act or the Exchange Act, each officer of the Issuer, the Company
or any Guarantor who shall have signed the Registration Statement and each
director of the Issuer, the Company or any Guarantor shall have the same rights
to contribution as the Issuer, the Company and the Guarantors, subject in each
case to the applicable terms and conditions of this paragraph (d).

                  (e)      The provisions of this Section will remain in full
force and effect, regardless of any investigation made by or on behalf of any
Holder or the Issuer, the Company or any Guarantor or any of the officers,
directors or controlling Persons referred to in this Section hereof, and will
survive the sale by a Holder of securities covered by a Registration Statement.

                  7.       Underwritten Registrations. (a) If any of the
Securities or New Securities, as the case may be, covered by any Shelf
Registration Statement are to be sold in an underwritten offering, the Managing
Underwriters shall be selected by the Majority Holders.

                  (b)      No Person may participate in any underwritten
offering pursuant to any Shelf Registration Statement, unless such Person (i)
agrees to sell such Person's Securities or New Securities, as the case may be,
on the basis reasonably provided in any underwriting arrangements approved by
the Persons entitled hereunder to approve such arrangements; and (ii)

                                       17



completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements.

                  8.       No Inconsistent Agreements. The Issuer, the Company
and the Guarantors have not, as of the date hereof, entered into, nor shall
they, on or after the date hereof, enter into, any agreement with respect to
their securities that is inconsistent with the rights granted to the Holders
herein or otherwise conflicts with the provisions hereof.

                  9.       Amendments and Waivers. The provisions of this
Agreement, including the provisions of this sentence, may not be amended,
qualified, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given, unless the Issuer, the Company and the
Guarantors have obtained the written consent of the Majority Holders (or, after
the consummation of any Registered Exchange Offer in accordance with Section 2
hereof, of New Securities); provided that, with respect to any matter that
directly or indirectly affects the rights of any Initial Purchaser hereunder,
the Issuer, the Company and the Guarantors shall obtain the written consent of
each such Initial Purchaser against which such amendment, qualification,
supplement, waiver or consent is to be effective. Notwithstanding the foregoing
(except the foregoing proviso), a waiver or consent to departure from the
provisions hereof with respect to a matter that relates exclusively to the
rights of Holders whose Securities or New Securities, as the case may be, are
being sold pursuant to a Registration Statement and that does not directly or
indirectly affect the rights of other Holders may be given by the Majority
Holders, determined on the basis of Securities or New Securities, as the case
may be, being sold rather than registered under such Registration Statement.

                  10.      Notices. All notices and other communications
provided for or permitted hereunder shall be made in writing by hand-delivery,
first-class mail, telex, telecopier or air courier guaranteeing overnight
delivery:

                  (a)      if to a Holder, at the most current address given by
such holder to the Company in accordance with the provisions of this Section,
which address initially is, with respect to each Holder, the address of such
Holder maintained by the Registrar under the Indenture, with a copy in like
manner to Citigroup Global Markets Inc;

                  (b)      if to you, initially at the respective addresses set
forth in the Purchase Agreement; and

                  (c)      if to the Issuer, the Company or any Guarantor,
initially at its address set forth in the Purchase Agreement.

                  All such notices and communications shall be deemed to have
been duly given when received.

                  The Initial Purchasers or the Issuer, the Company and the
Guarantors by notice to the other parties may designate additional or different
addresses for subsequent notices or communications.

                                       18



                  11.      Successors. This Agreement shall inure to the benefit
of and be binding upon the successors and assigns of each of the parties,
including, without the need for an express assignment or any consent by the
Issuer, the Company and the Guarantors thereto, subsequent Holders of Securities
and the New Securities. Each of the Issuer, the Company and the Guarantors
hereby agrees to extend the benefits of this Agreement to any Holder of
Securities and the New Securities, and any such Holder may specifically enforce
the provisions of this Agreement as if an original party hereto.

                  12.      Counterparts. This agreement may be in signed
counterparts, each of which shall an original and all of which together shall
constitute one and the same agreement.

                  13.      Headings. The headings used herein are for
convenience only and shall not affect the construction hereof.

                  14.      Applicable Law. This Agreement shall be governed by
and construed in accordance with the laws of the State of New York applicable to
contracts made and to be performed in the State of New York.

                  15.      Severability. In the event that any one of more of
the provisions contained herein, or the application thereof in any
circumstances, is held invalid, illegal or unenforceable in any respect for any
reason, the validity, legality and enforceability of any such provision in every
other respect and of the remaining provisions hereof shall not be in any way
impaired or affected thereby, it being intended that all of the rights and
privileges of the parties shall be enforceable to the fullest extent permitted
by law.

                  16.      Securities Held by the Company or Arch Western, etc.
Whenever the consent or approval of Holders of a specified percentage of
principal amount of Securities or New Securities is required hereunder,
Securities or New Securities, as applicable, held by the Company or Arch
Western, or their Affiliates (other than subsequent Holders of Securities or New
Securities if such subsequent Holders are deemed to be Affiliates solely by
reason of their holdings of such Securities or New Securities) shall not be
counted in determining whether such consent or approval was given by the Holders
of such required percentage.

                                       19

                  Each Broker-Dealer that receives New Securities for its own
account pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such New Securities. The Letter of
Transmittal states that by so acknowledging and by delivering a prospectus, a
Broker-Dealer will not be deemed to admit that it is an "underwriter: within the
meaning of the Securities Act. This Prospectus, as it may be amended or
supplemented from time to time, may be used by a Broker-Dealer in connection
with resales of New Securities received in exchange for Securities where such
Securities were acquired by such Broker-Dealer as a result of market-making
activities or other trading activities. The Issuer and the Guarantors have
agreed that, starting on the Expiration Date (as defined herein) and ending on
the close of business one year after the Expiration Date, they will make this
Prospectus available to any Broker-Dealer for use in connection with any such
resale. See "Plan of Distribution".



                                                                         ANNEX B

                  Each Broker-Dealer that receives New Securities for its own
account in exchange for Securities, where such Securities were acquired by such
Broker-Dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such New Securities. See "Plan of Distribution".



                                                                         ANNEX C

                  Each Broker-Dealer that receives New Securities for its own
account pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such New Securities. This
Prospectus, as it may be amended or supplemented from time to time, may be used

exchange for Securities where such Securities were acquired as a result of
market-making activities or other trading activities. The Issuer and the
Guarantors have agreed that, starting on the Expiration Date and ending on the
close of business 180 days after the Expiration Date, they will make this
Prospectus, as amended or supplemented, available to any Broker-Dealer for use

dealers effecting transactions in the New Securities may be required to deliver

from time to time in one or more transactions in the over-the-counter market, in
negotiated transactions, through the writing of options on the New Securities or
a combination of such methods of resale, at market prices prevailing at the time

prices. Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such Broker-Dealer and/or the purchasers of any such New
Securities. Any Broker-Dealer that resales New Securities that were received by
it for its own account pursuant to the Exchange Offer and any broker or dealer
that participates in a distribution of such New Securities may be deemed to be
an "underwriter" within the meaning of the Securities Act and any profit of any
such resale of New Securities and any commissions or concessions received by any
such Persons may be deemed to be underwriting compensation under the Securities
Act. The Letter of Transmittal states that by acknowledging that it will deliver
and by delivering a prospectus, a Broker-Dealer will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act.

                  For a period of 180 days after the Expiration Date, the Issuer
and the Guarantors will promptly send additional copies of this Prospectus and
any amendment or supplement to this Prospectus to any Broker-Dealer that
requests such documents in the Letter of Transmittal. The Issuer and the
Guarantors have agreed to pay all expenses incident to the Exchange Offer
(including the expenses of one counsel for the holder of the Securities) other
than commissions or concessions of any brokers or dealers and will indemnify the
holders of the Securities (including any Broker-Dealers) against certain
liabilities, including liabilities under the Securities Act.

Arch Western Finance, LLC
One CityPlace Drive, Suite 300
St. Louis, MO  63141

Ladies and Gentlemen:

         I am the Vice President-Law and General Counsel of Arch Coal, Inc., a
Delaware corporation ("Arch Coal"), and have acted as counsel to Arch Western
Finance, LLC, a Delaware limited liability company (the "Company"), Arch Western
Resources, LLC, a Delaware limited liability company ("Arch Western"), Arch of
Wyoming, LLC, a Delaware limited liability company ("Arch of Wyoming"), Mountain
Coal Company, L.L.C., a Delaware limited liability company ("Mountain Coal") and
Thunder Basin Coal Company, L.L.C., a Delaware limited liability company
("Thunder Basin" and with Arch Western, Arch of Wyoming and Mountain Coal
collectively, the "Guarantors") in connection with the Registration Statement of
Form S-4 (the "Registration Statement") filed by the Company and the Guarantors
with the Securities and Exchange Commission (the "SEC") under the Securities Act
of 1933, as amended, relating to the issuance by the Company of $700,000,000
aggregate principal amount of its 6 3/4 Senior Notes due 2013 (the "Exchange
Notes") and the issuance by the Guarantors of guarantees (the "Guarantees"),
with respect to the Exchange Notes. The Exchange Notes will be offered by the
Company in exchange for $700,000,000 aggregate principal amount of its
outstanding 6 3/4% Senior Notes due 2013. The Exchange Notes and the GuaranteeS
will be issued under an indenture dated as of June 25, 2003 (the "Indenture")
among the Company, the Guarantors and The Bank of New York, as trustee.

         In connection with rendering the opinions set forth below, I have
examined the Registration Statement, the Prospectus contained therein, the
Indenture, which has been filed with the SEC as exhibit to the Registration
Statement, the respective constituent documents of the Company and the
Guarantors and resolutions adopted by the respective managing members of the
Company and the Guarantors, and I have made such other investigation as I have
deemed appropriate. As to questions of fact material to this opinion letter, I
have examined and relied upon certificates of public officials. I have not
independently established any of the facts so relied on.

         For purposes of this opinion letter, I have made the assumptions that
are customary in opinion letters of this kind, including the assumptions that
each document submitted to me is accurate and complete, that each such document
that is an original is authentic, that each such document that is a copy
conforms to an authentic original and that all signatures (other than signatures
on behalf of the Company, the Guarantors or Arch Coal) on each such document are
genuine. I further have assumed the legal capacity of natural persons, and I
have assumed that each party to the documents I have examined or relied on
(other than the Company, the




Arch Western Finance, LLC
July__, 2003
Page 2

Guarantors or Arch Coal) has the legal capacity or authority and has satisfied
all legal requirements that are applicable to that party to the extent necessary
to make such documents enforceable against that party. I have not verified any
of those assumptions.

         The opinions expressed in this opinion letter are limited to the laws
of the State of Missouri (excluding its conflict of laws rules) and the Limited
Liability Company Act of the State of Delaware. I am not opining on, and I
assume no responsibility for, the applicability to or effect on any of the
matters covered herein of any other laws, the laws of any other jurisdiction or
the local laws of any jurisdiction.

         Based on the foregoing, and subject to the foregoing and the additional
qualifications and other matters set forth below, it is my opinion that:

         1.       When the Exchange Notes have been duly executed,
authenticated, issued and delivered in accordance with the provisions of the
Indenture upon the exchange, the Exchange Notes will constitute valid and
legally binding obligations of the Company enforceable against the Company in
accordance with their terms.

         2.       When (a) the Exchange Notes have been duly executed,
authenticated, issued and delivered in accordance with the provisions of the
Indenture upon the exchange and (b) the Guarantees have been duly endorsed on
the Exchange Notes, the Guarantees will constitute valid and legally binding
obligations of the Guarantors enforceable against the Guarantors in accordance
with their terms.

         My opinions set forth above are subject to the effects of (i)
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
other similar laws relating to or affecting creditors' rights generally; (ii)
general equitable principles (whether considered in a proceeding in equity or at
law) and (iii) an implied covenant of good faith and fair dealing.

         I am furnishing this opinion letter to you solely in connection with
the Registration Statement filed by the Company and the Guarantors with the SEC
under the Securities Act of 1933, as amended, relating to the issuance by the
Company of the Exchange Notes and the issuance by the Guarantors of the
Guarantees. You may not rely on this opinion letter in any other connection, and
it may not be furnished to or relied upon by any other person for any purpose,
without my specific prior written consent. This opinion is as of the date
hereof, and I have not undertaken to supplement this opinion with respect to
factual matters or changes in law which may hereafter occur.

                  I hereby consent to the filing of this opinion letter as
Exhibit 5 to the Registration Statement and to the use of my name under the
caption "Legal Matters" in the Prospectus included in the Registration
Statement.

                                          Yours truly,
