PART I Item 1. BUSINESS General Arch Coal, Inc. ("Arch Coal" or the "Company") is one of the largest coal producers in the United States. The Company mines, processes and markets compliance and low-sulfur coal from mines located in both the eastern and western United States, enabling it to ship coal cost-effectively to most of the major domestic coal-fired electric generation facilities. As of December 31, 2001, the Company had 25 operating mines and controlled approximately 3.43 billion tons of proven and probable coal reserves, approximately 1.83 billion tons of which were assigned reserves and approximately 1.60 billion tons of which were unassigned reserves. Arch Coal sold 109.5 million tons of coal in 2001. The Company sells substantially all of its coal to producers of electric power. The Company owns a 99% membership interest in Arch Western Resources, LLC ("Arch Western"), a joint venture that was formed in connection with the Company's acquisition of the United States coal operations of Atlantic Richfield Company on June 1, 1998. The principal operating units of Arch Western are Thunder Basin Coal Company, L.L.C., which operates the Black Thunder mine in the Southern Powder River Basin in Wyoming; Mountain Coal Company, L.L.C., which operates the West Elk mine in Colorado; Canyon Fuel Company, LLC ("Canyon Fuel"), which operates three mines in Utah; and Arch of Wyoming, LLC, which operates two mines in the Hanna Basin of Wyoming. Arch Western owns 100% of the membership interests of Thunder Basin Coal Company, L.L.C., Mountain Coal Company, L.L.C. and Arch of Wyoming, LLC. Arch Western owns a 65% membership interest in Canyon Fuel, with the remaining 35% membership interest owned by ITOCHU Coal International Inc., a subsidiary of ITOCHU Corporation of Japan. Business Environment United States Coal Markets. Production of coal in the United States has increased from 434 million tons in 1960 to over 1.1 billion tons in 2001. The following table sets forth demand trends for United States coal by consuming sector through 2020 as compiled, preliminary(p) or forecasted(f) by the United States Department of Energy/Energy Information Agency. Annual Growth 2000- Consumption by Sector 1999 2000 2001p 2005f 2010f 2015f 2020f 2020f - -------------------------------- -------- -------- ------- ------- ------- ------- ------- ----------- (tons in millions) Electric Generation ............ 953 991 1,013 1,065 1,141 1,183 1,366 1.3% Industrial ..................... 65 65 62 80 81 83 86 0.2% Steel Production ............... 28 29 27 26 24 22 20 (1.9%) Residential/Commercial ......... 5 5 4 5 6 6 6 0.8% Export ......................... 58 58 49 56 54 53 55 (0.3%) ----- ----- ----- ----- ----- ----- ----- --- Total ......................... 1,109 1,148 1,155 1,232 1,306 1,347 1,533 1.2% ===== ===== ===== ===== ===== ===== ===== === Electricity Generation. Coal has consistently maintained a 50% to 53% market share over competing energy sources to generate electricity during the past ten years because of its relatively low cost and its availability throughout the United States. Coal is the lowest cost fossil-fuel used for base-load electric power generation--considerably less expensive than natural gas or oil. Coal-fired generation is also competitive with nuclear power generation, especially on an all-in cost per megawatt-hour basis. Hydroelectric power is inexpensive but is limited by both geography and susceptibility to seasonal and climatic conditions. Non hydropower renewable power generation accounts for less than 3% of all the electricity generated in the U.S. and is limited by resources and/or technology. Consequently, approximately 88% of the coal produced in the United States in 2001 was sold in the domestic market as a fuel to the electric generation segment. The remainder of the tons were sold in 2001 as steam coal for industrial 1

and residential purposes, into the export market, and as metallurgical coal. In addition to the relative competitiveness of coal-fired generation plants, coal consumption patterns are also influenced by the demand for electricity, governmental regulation impacting coal production and power generation, technological developments and the location, availability and quality of competing sources of coal, as well as alternative fuels such as natural gas, oil and nuclear and alternative energy sources such as hydroelectric power. Long-term demand for electric power will depend upon a variety of economic, regulatory, technological and climatic factors beyond our control. Historically, domestic demand for electric power has increased as the United States economy has grown. Two important regulatory initiatives, one designed to increase competition among utilities and lower the cost of electricity for consumers, and another to improve air quality by reducing the level of sulfur emitted from coal-burning power generation plants, have had and are expected to continue to have significant effects on the electric utility industry and its coal suppliers. According to the Energy Information Agency, coal is expected to remain the primary fuel for electricity generation through 2020. The following table sets forth the source fuel for electricity generation from 1990 through 2020 as compiled, preliminary(p), annualized(a) or forecasted(f) by the Energy Information Agency. 1990 1995 2000p 2001a 2005f 2010f 2015f 2020f ------- ------- ------- ------- ------- ------- ------- -------- (billion kilowatt hours) Coal .......................... 1,590 1,710 1,968 1,980 2,135 2,264 2,341 2,472 Petroleum ..................... 124 75 109 145 49 38 43 49 Natural Gas ................... 378 499 597 642 847 1,153 1,488 1,733 Nuclear ....................... 577 673 754 771 759 737 707 702 Hydro/Renewable/other ......... 356 401 373 324 429 452 472 488 ----- ----- ----- ----- ----- ----- ----- ----- Total ........................ 3,025 3,358 3,801 3,862 4,219 4,644 5,051 5,444 ===== ===== ===== ===== ===== ===== ===== ===== Coal's primary advantage is its relatively low cost compared to other fuels used to generate electricity.

When the Company's coal sales contracts expire or are terminated, it is exposed to the risk of having to sell coal into the spot market, where demand is variable and prices are subject to greater volatility. Historically, the price of coal sold under long-term contracts has exceeded prevailing spot prices for coal. However, in the past several years new contracts have been priced at or near existing spot rates. The terms of the Company's coal sales contracts result from bidding and extensive negotiations with customers. Consequently, the terms of these contracts typically vary significantly in many respects, including price adjustment features, provisions permitting renegotiation or modification of coal sale prices, coal quality requirements, quantity parameters, flexibility and adjustment mechanisms, permitted sources of supply, treatment of environmental constraints, options to extend and force majeure, suspension, termination and assignment provisions. Provisions permitting renegotiation or modification of coal sale prices are present in many of the Company's more recently negotiated long-term contracts and usually occur midway through a contract or every two to three years, depending upon the length of the contract. In some circumstances, customers have the option to terminate the contract if prices have increased by a specified percentage from the price at the commencement of the contract or if the parties cannot agree on a new price. The term of sales contracts has decreased significantly over the last two decades as competition in the coal industry has increased and, more recently, as electricity generators have prepared themselves for federal Clean Air Act requirements and the impending deregulation of their industry. There are some contract terms that differ between a standard "eastern United States" contract and a standard "western United States" contract. In the eastern United States, many customers require that the coal be sampled and weighed at the destination. In the western United States, virtually all samples are taken at the source. More eastern United States coal is purchased on the spot market. The eastern United States market has more recently been a shorter-term market because of the larger number of smaller 3

mining operations in that region. Western United States contracts sometimes stipulate that some production taxes and coal royalties be reimbursed in full by the buyer rather than as a pricing component within the contract. These items comprise a significant portion of western United States coal pricing. A factor that may impact the Company's sale of coal in the future is the development of coal commodity trading. The New York Mercantile Exchange initiated electricity commodity trading a few years ago and has recently initiated coal contract trading. The coal contract trading is based on a Huntington, West Virginia barge loading hub. In addition, some brokerage and marketing firms have entered the coal markets and devised transactions that mimic commodity activity. Today, limited, but growing, over-the-counter trading is being conducted on both firm-forward transactions as well as put, call and other options. The trend to more commodity-type transactions could mark a significant change in how coal is sold. The Company is unable to predict whether this trend will have a material effect on its sales and whether any such effect would be positive or negative on its operating results. Competition The coal industry is intensely competitive, primarily as a result of the existence of numerous producers in the coal producing regions in which the Company operates. The Company competes with several major coal producers in the Central Appalachian and Powder River Basin areas. It also competes with a number of smaller producers in those and its other market regions. Operations As of December 31, 2001, the Company operated a total of 25 mines, all located in the United States. Coal is transported from the Company's mining complexes to customers by means of railroad cars, river barges or trucks, or a combination of these means of transportation. As is customary in the industry, virtually all the Company's 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 a summary of information regarding the Company's principal mining complexes and the coal reserves associated with these operations as of December 31, 2001: 4

- ---------- (1) Amounts in parenthesis indicate the number of captive and contract mines at the mining complex or location. Captive mines are mines which the Company owns and operates on land owned or leased by it. Contract mines are mines which other operators mine for the Company under contracts on land owned or leased by the Company. (2) Reported for captive operations only. (3) The Company idled its mining operations at the Dal-Tex complex on July 23, 1999 due to a delay in obtaining mining permits resulting from legal action in the U.S. District Court for the Southern District of West Virginia. (4) Utilizes an 83-cubic-yard dragline and a 51-cubic-yard shovel. A dragline is a large machine used in the surface mining process to remove layers of earth and rock covering coal. (5) Utilizes a 49-cubic-yard dragline, a 43-cubic-yard shovel, a 22-cubic-yard shovel and a 28-cubic-yard loader at the Ruffner mine. (6) Utilizes a 118-cubic-yard dragline, two 53-cubic-yard shovels and three 28-cubic-yard loaders. (7) Utilizes 170-cubic-yard, 130-cubic-yard, 90-cubic-yard and 45-cubic-yard draglines and 53-cubic-yard, 60-cubic-yard and 82-cubic-yard shovels. (8) The Company idled its mining operations at Coal Creek during the third quarter of 2000 because its cost structure was not competitive in the market environment that existed at that time. (9) Mines are operated by Canyon Fuel. Canyon Fuel is an equity investment and its financial statements and tons produced are not consolidated into the Company's financial statements and tons produced. Amounts represent 100% of Canyon Fuel's production and assigned reserves of which the Company has a 65% interest. (10) Utilizes 76-cubic-yard and 64-cubic-yard draglines at Medicine Bow and a 32-cubic-yard dragline at Seminoe II. (11) Reflects the cost of plant, equipment and development at the mine as of December 31, 2001. Transportation Coal from the mines of the Company's subsidiaries is transported by rail, truck and barge to domestic customers and to Atlantic or Pacific coast terminals for shipment to domestic and international customers. The Company's Arch Coal Terminal is located on a 60-acre site on the Big Sandy River approximately seven miles upstream from its confluence with the Ohio River. Arch Coal Terminal provides coal storage and transloading services. Company subsidiaries together own a 17.5% interest in Dominion Terminal Associates ("DTA"), which leases and operates a ground storage-to-vessel coal transloading facility (the "DTA Facility") in Newport News, Virginia. The DTA Facility has a rated throughput capacity of 20 million tons of coal per year and ground storage capacity of approximately 1.7 million tons. The DTA Facility serves international customers, as well as domestic coal users located on the eastern seaboard of the United States. As of December 31, 2001, Arch Western owned a 5.3% equity interest and Canyon Fuel owned a 9.0% equity interest in the Los Angeles Export Terminal ("LAXT"), which owns and operates a dry bulk terminal operation within the Port of Los Angeles. LAXT is served by the Union Pacific railroad. Current annual rated capacity at the terminal is 10 million tons. The City of Los Angeles owns the land upon which the facility has been constructed. LAXT has entered into a 35 year lease with the City which provides compensation for its contribution of cash and land to the venture. The total cost of the facility was approximately $144 million.

Glossary of Selected Mining Terms Assigned Reserves. Recoverable coal reserves that have been designated for mining by a specific operation. Auger Mining. Auger mining employs a large auger, which functions much like a carpenter's drill. The auger bores into a coal seam and discharges coal out of the spiral onto waiting conveyor belts. After augering is completed, the openings are reclaimed. This method of mining is usually employed to recover any additional coal left in deep overburden areas that cannot be reached economically by other types of surface mining. Btu--British Thermal Unit. A measure of the energy required to raise the temperature of one pound of water one degree Fahrenheit. Coal Seam. A bed or stratum of coal. Coal Washing. The process of removing impurities, such as ash and sulfur based compounds, from coal. Compliance Coal. Coal which, when burned, emits 1.2 pounds or less of sulfur dioxide per million Btus. Compliance coal requires no mixing with other coals or use of sulfur dioxide reduction technologies by generators of electricity to comply with the requirements of the federal Clean Air Act. Continuous Mining. One of two major underground mining methods now used in the United States (also see "Longwall Mining"). This process utilizes a machine--a "continuous miner"--that mechanizes the entire coal extraction process. The continuous miner removes or "cuts" the coal from the seam. The loosened coal then falls on a conveyor for removal to a shuttle car or larger conveyor belt system. 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 now used in the United States (see also "Continuous Mining"). 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. 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 reserves, but the sites for inspection, sampling and measurement are farther apart; therefore, 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. 7

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 shaping 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. 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. Surface Mine. A mine in which the coal lies near the surface and can be extracted by removing overburden. Tons. References to a "ton" mean a "short" or net tonne, which is equal to 2,000 pounds. Unassigned Reserves. Recoverable coal reserves that have not yet been designated for mining by a specific Company 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.

PROPERTIES The Company estimates that it owned or controlled, as of December 31, 2001, approximately 3.43 billion tons of proven and probable recoverable reserves, approximately 1.83 billion tons of which were assigned reserves and approximately 1.60 billion tons of which were unassigned reserves. Assigned reserves are recoverable coal reserves that have been designated to be mined by a specific operation. Unassigned reserves are recoverable reserves that have not yet been designated for mining by a specific Company operation. Recoverable reserves include only saleable coal and do not include coal which would remain unextracted, such as for support pillars, and processing losses, such as washery losses. Reserve estimates are prepared by the Company's 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. The following table presents the Company's estimated recoverable coal reserves at December 31, 2001: 9

Over 98% of the Company's recoverable reserves consists of steam coal, which is coal used in steam boilers to make electricity. Less than 2% of the Company's recoverable reserves consists of metallurgical coal, which is a grade of coal used in the production of steel. Metallurgical coal represents an immaterial amount of the Company's operations. As of December 31, 2001, approximately 86,528 acres (which includes 100% of the acreage held by Canyon Fuel) out of the Company's total of approximately 670,000 acres of coal land was leased from the federal government. These leases have terms expiring between 2001 and 2019, subject to readjustment or extension and to earlier termination for failure to meet diligent development requirements. The Company has entered into leases covering substantially all of its leased reserves which are not scheduled to expire prior to expiration of projected mining activities. The Company also controls, through ownership or long-term leases, approximately 5,310 acres of land which are used either for its coal processing facilities or are being held for possible future development. Royalties are paid to lessors either as a fixed-price per-ton or as a percentage of the gross sales price of the mined coal. The Company pays percentage-based royalties under the majority of its significant leases. The terms of most of these leases extend until the exhaustion of mineable and merchantable coal. The remaining leases have initial terms ranging from one to 40 years from the date of their execution, with most containing options to renew. In some cases, a lease bonus, or prepaid royalty, is required, payable either at the time of execution of the lease or in annual installments. In most cases, the prepaid royalty amount is applied to reduce future production royalties. 10

The Pine Creek, Black Bear, Campbells Creek, Samples, Ruffner and Holden 25/Ragland preparation plants and related loadout facilities are located on properties held under leases which expire at varying dates over the next thirty years with either optional 20-year extensions or with unlimited extensions, and the balance of the Company's preparation plants and loadout facilities are located on property owned by the Company. All of the identified coal reserves held by the Company's subsidiaries have been subject to preliminary coal seam analysis to test sulfur content. Of these reserves, approximately 66% consist of compliance coal while an additional 25% could be sold as low-sulfur coal. The balance is classified as high-sulfur coal. Some of the Company's low-sulfur coal can be marketed as compliance coal when blended with other compliance coal. Accordingly, most of the Company's reserves are primarily suitable for the domestic steam coal markets. However, a substantial portion of the low-sulfur and compliance coal reserves at the Mingo Logan operations may also be used as a high-volatile, low-sulfur, metallurgical coal. Title to coal properties held by lessors or grantors to the Company and its subsidiaries and the boundaries of properties are normally 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 the Company's independent operating subsidiaries 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. From time to time, lessors or sublessors of land leased by the Company's subsidiaries have sought to terminate such leases on the basis that such subsidiaries have failed to comply with the financial terms of the leases or that the mining and related operations conducted by such subsidiaries are not authorized by the leases. Some of these allegations relate to leases upon which the Company conducts operations material to the Company's consolidated financial position, results of operations and liquidity, but the Company does not believe any pending claims by such lessors or sublessors have merit or will result in the termination of any material lease or sublease. The Company must obtain permits from applicable state regulatory authorities before it begins to mine particular 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. The Company is required to post bonds to secure performance under its permits. As is typical in the coal industry, the Company strives to obtain mining permits within a time frame that allows it to mine reserves as planned on an uninterrupted basis. The Company generally begins preparing applications for permits for areas that it intends 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. The Company's reported coal reserves are those that could be economically and legally extracted or produced at the time of their determination. In determining whether the Company's reserves meet this standard, it takes into account, among other things, the Company's 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. Except as described elsewhere in this document with respect to permits to conduct mining operations involving valley fills, which has been taken into account in determining the Company's reserves, the Company is not currently aware of matters which would significantly hinder its ability to obtain future mining permits with respect to its reserves. The carrying cost of the Company's coal reserves at December 31, 2001 (which does not include the Company's 65% share of Canyon Fuel) was $902.0 million, consisting of $37.2 million of prepaid royalties and the $864.8 million net book value of coal lands and mineral rights. 11

The Company's executive headquarters occupy approximately 50,000 square feet of leased space at One CityPlace Drive, in St. Louis, Missouri. See "Item 1. Business" for a further description of the Company's subsidiaries' mining complexes, mines, transportation facilities and other operations.

Management's Discussion and Analysis - -------------------------------------------------------------------------------- Forward-Looking Statements Statements in this annual report which are not statements of historical fact are forward-looking statements within the "safe harbor" provision of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on the information available to, and the expectations and assumptions deemed reasonable by, the Company at the time the statements are made. Because these forward-looking statements are subject to various risks and uncertainties, actual results may differ materially from those projected in the statements. These expectations, assumptions and uncertainties include: the Company's expectation of continued growth in the demand for electricity; belief that legislation and regulations relating to the Clean Air Act and the relatively higher costs of competing fuels will increase demand for its compliance and low-sulfur coal; expectation of continued improved market conditions for the price of coal; expectation that the Company will continue to have adequate liquidity from its cash flow from operations, together with available borrowings under its credit facilities, to finance the Company's working capital needs; a variety of operational, geologic, permitting, labor and weather-related factors; and the other risks and uncertainties which are described below under "Contingencies" and "Certain Trends and Uncertainties." Results of Operations 2001 Compared to 2000 Net Income (Loss). The Company had net income of $7.2 million for the year ended December 31, 2001 compared to a net loss of $12.7 million for the 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 and by reduced interest expense associated with lower debt levels. The current year results were negatively impacted by production difficulties and increased costs at the Company's West Elk mine in Gunnison County, Colorado, caused by high methane levels and at the Samples surface operation in West Virginia caused by a sandstone intrusion into the principal coal seam. Results for the year ended December 31, 2001 were also positively impacted by the following other items: (1) A $9.4 million pre-tax insurance settlement as part of the Company's coverage under its property and business interruption policy. The insurance settlement represents the final settlement for losses incurred for the prior year West Elk mine idling described below. (2) A $7.4 million pre-tax gain from a state tax credit covering prior periods. (3) A $4.6 million pre-tax gain as a result of progress in processing claims associated with the recovery of certain previously paid excise taxes on export sales. The gain stems from an IRS notice during the second quarter of 2000 outlining the procedures for obtaining tax refunds on black lung excise taxes paid by the industry on export sales. The notice was the result of a 1998 federal district court decision that found such taxes to be unconstitutional. Of the $4.6 million recognized, $3.1 million represents the interest component of the claim and was recorded as interest income. (4) An increase of pre-tax income of $7.5 million primarily from a reduction in the amount of expected reclamation work at the Company's idle Illinois properties resulting from permit revisions. (5) A $13.5 million pre-tax gain primarily on the sale of land. These items were partially offset by a pre-tax charge of $4.1 million for stock-based compensation benefits that may be realized in future periods and by an increase in the litigation reserve reducing pre-tax income by $5.6 million resulting from several litigation settlements. Results for the year ended December 31, 2000 were adversely impacted by operating losses incurred at the West Elk mine offset to some extent by partial pre-tax insurance settlements of $31.0 million received throughout 2000 under the 2001 Annual Report page 23. - --------------------------------------------------------------------------------

Company's business interruption policy. The mine was idled from January 28, 2000 to July 12, 2000 following the detection of combustion gases in a portion of the mine. These combustion gases are unrelated to the high methane levels experienced at the mine in 2001. Results for the year ended December 31, 2000 were also positively impacted by the following other items: (1) Pre-tax gains of $21.8 million resulting from the settlement of certain workers' compensation liabilities with the State of West Virginia. This was partially offset by adjustments to other workers' compensation liabilities resulting from changes in estimates that caused increases to the liability of $13.5 million. The net workers' compensation adjustment was a pre-tax gain of $8.3 million. (2) A pre-tax gain of $7.8 million resulting from a reduction in the Company's reclamation liability due to permit revisions at its idle mine properties in Illinois. (3) A $12.1 million pre-tax gain primarily on the sale of land. (4) A pre-tax gain of $12.7 million related to excise tax recoveries on export shipments in connection with the IRS notice described above. (5) A $9.8 million pre-tax curtailment gain resulting from previously unrecognized postretirement benefit changes that occurred from plan amendments in previous years. The West Elk mine's coal sales for the year ended December 31, 2001 of $77.0 million were $35.5 million greater than its sales of $41.5 million in 2000, although the mine experienced significant production difficulties during both periods as described above. This compares to $110.3 million of coal sales during the year ended December 31, 1999, a period of uninterrupted production. Excluding the impact of the related insurance recoveries, operating losses for the mine for 2001 and 2000 were $11.3 million and $43.4 million, respectively, compared to operating income of $13.1 million during 1999. At the Samples surface operation, a sandstone intrusion caused the coal seam to thin, which resulted in lower production and higher associated costs. During the year ended December 31, 2001, the Samples surface operation incurred an operating loss of $19.2 million compared to operating income of $4.3 million during the same period of 2000. Revenues. Total revenues for the year ended December 31, 2001 were $1,488.7 million, an increase of $84.1 million from the same period in the prior year. This increase was the result of several factors including the increase in sales at West Elk when compared to the same period in the prior year, improved pricing on the limited tonnage that was open to market-based pricing during the current period, and increased pass-through transportation revenues. Income From Equity Investment. During the year ended December 31, 2001, Canyon Fuel, the Company's equity method investment, recognized recoveries of previously paid property taxes. The Company's share of these recoveries is $2.6 million, which is reflected as income from equity investment in the Consolidated Statements of Operations. In addition, Canyon Fuel experienced improved performance at its three underground mines in Utah. Income From Operations. The following table presents income from operations excluding the unusual items discussed above. Year ended December 31 (in millions) 2001 2000 Income from operations (as reported) $ 62.5 $ 74.0 Losses at the West Elk mine 11.3 43.4 West Elk mine insurance recoveries (9.4) (31.0) Samples surface operation losses 19.2 - Land sales (13.5) (12.1) Reclamation adjustment - Illinois properties (7.5) (7.8) Stock-based compensation accrual 4.1 - State tax credit (7.4) - Litigation settlement 5.6 - Workers' compensation adjustment - (8.3) Postretirement medical benefit curtailment - (9.8) Black lung excise tax recoveries (1.5) (12.7) Canyon Fuel Company property tax recoveries (2.6) - ------------------------- Adjusted income from operations $ 60.8 $ 35.7 ========================= Arch Coal, Inc. page 24. - --------------------------------------------------------------------------------

The increase in adjusted income from operations is primarily attributable to improved pricing on the limited coal tonnage that was open to market-based pricing during the current year; improved performance at the Company's Black Thunder mine in Wyoming and the Canyon Fuel operations in Utah; and continued strong performance at the Company's Mingo Logan operation in West Virginia. Selling, General and Administrative Expenses. Selling, general and administrative expenses increased by $4.9 million. The increase was primarily attributable to the stock-based compensation charge discussed above. Amortization of Coal Supply Agreements. Amortization of coal supply agreements decreased by $12.3 million primarily as a result of the expiration and buy-out of above-market contracts that were valued as assets and amortized on the Company's balance sheet in the prior year. Interest Expense. Interest expense decreased by $27.9 million primarily as a result of lower debt levels in the year ended December 31, 2001 compared to the same period of 2000. The net proceeds from two public stock offerings in the first half of 2001 were used to significantly reduce debt levels from the prior year (see additional discussion in "Liquidity and Capital Resources"). Interest Income. The increase in interest income of $2.9 million over the prior year was primarily due to recognition of the interest component of the black lung excise tax recovery recognized in 2001. Income Taxes. The Company's effective tax rate is sensitive to changes in estimates of annual profitability and percentage depletion. The income tax benefit recorded for the year ended December 31, 2001 is primarily the result of the impact of percentage depletion. During 1999, the Company determined that as it relates to future income taxes, the Company did not anticipate recognizing all of its alternative minimum tax credit carryforwards in the future and only expected to recognize part of the benefit of its deferred tax asset at the alternative minimum tax rate of approximately 24%. Therefore, the Company has recorded a valuation allowance for a portion of its deferred tax assets that management believes, more likely than not, will not be realized. Realization of the deferred tax assets is principally dependent upon the Company achieving projected future taxable income. The judgments regarding future profitability may change due to market conditions or the Company's ability to execute its operating plans. These changes, if any, may require the Company to adjust the deferred tax asset balances and would impact income tax expense. Adjusted EBITDA. Adjusted EBITDA (income from operations before the effect of net interest expense; income taxes; and depreciation, depletion and amortization of the Company, its subsidiaries and its ownership percentage in its equity investments) was $282.3 million for the year ended December 31, 2001 compared to $315.2 million in 2000. This decrease is primarily attributable to the losses incurred at the Samples surface operation resulting from the sandstone intrusion during 2001. Adjusted EBITDA should not be considered in isolation or as an alternative to net income, operating income, or cash flows from operations or as a measure of a company's profitability, liquidity or performance under generally accepted accounting principles. 2000 Compared to 1999 Net Income (Loss). The Company incurred a net loss of $12.7 million for the year ended December 31, 2000 compared to a net loss of $346.2 million for the year ended December 31, 1999. Results for 2000 were adversely impacted by the temporary idling of the West Elk mine in Gunnison County, Colorado, as described above. Also, as a result of permit revisions at its idle mine properties in Illinois, the Company reduced its reclamation liability at that location by $7.8 million, which favorably impacted results for 2000. In addition, the Company recorded $12.7 million of pre-tax income related to black lung excise tax recoveries on export shipments in connection with the IRS notice described above. The Company also 2001 Annual Report page 25. - --------------------------------------------------------------------------------

settled certain workers' compensation liabilities with the state of West Virginia, resulting in pre-tax gains of $21.8 million. This was partially offset by adjustments to other workers' compensation liabilities resulting from changes in estimates which caused increases to the liability of $13.5 million. The net workers' compensation adjustment was a pre-tax gain of $8.3 million. During 2000, as a result of adjustments to employee post-employment medical benefits, the Company recognized $9.8 million of pre-tax curtailment gains described above. Other factors that affected year-to-year comparisons were primarily sales of land which resulted in pre-tax gains of $12.1 million during 2000 compared to $2.4 million in 1999. During 1999, the Company recorded a non-cash impairment charge of $364.6 million and charges of $23.1 million related to the restructuring of its administrative workforce and the closure of several operations. The Company also recorded a $112.3 million valuation allowance for a portion of its deferred tax assets and changed its method of depreciation on preparation plants and loadouts from straight-line to a units-of-production basis. The change in depreciation method resulted in an increase to income of $3.8 million net-of-tax, reported as a cumulative effect of accounting change in the consolidated statement of operations for 1999. Also, during the year ended December 31, 1999, the Company sold a dragline at the Arch of Illinois operation, resulting in a gain of $2.5 million, and also had settlements with two suppliers that added $6.5 million to the prior year's results. Revenues. Total revenues for the year ended December 31, 2000 were $1.4 billion, a decrease of 10% from the same period in the prior year as a result of several factors. These factors include reduced sales at the Company's West Elk mine as a result of the idling described above. Also, during the second half of 1999, the Company closed its Dal-Tex, Wylo and Arch of Illinois operations and two surface mines in Kentucky. Partially offsetting the decreased sales at the Company's closed eastern operations were increased sales at other eastern operations. The resulting decrease in production and sales from the Company's eastern operations was partially offset by increased production and sales at the Company's Black Thunder mine in Wyoming when compared to 1999. As a result, on a per-ton-sold basis, the Company's average selling price of $12.72 decreased $.86 from the prior year. Western coal, especially Powder River Basin coal, has a significantly lower average sales price than that provided from the Company's eastern coal operations, but is also significantly less costly to mine. Income From Operations. The following table presents income from operations excluding the unusual items discussed above. Year ended December 31 (in millions) 2000 1999 Income (loss) from operations (as reported) $ 74.0 $ (327.0) Losses (income) at the West Elk mine 43.4 (13.1) West Elk mine insurance recoveries (31.0) - Land sales (12.1) (2.4) AOI dragline sale - (2.5) Reclamation adjustment - Illinois properties (7.8) - Workers' compensation adjustment (8.3) - Postretirement medical benefit curtailment (9.8) - Black lung excise tax recoveries (12.7) - Write-down of impaired assets - 364.6 Restructuring charge - 23.1 Settlements with suppliers - (6.5) ----------------------- Adjusted income from operations $ 35.7 $ 36.2 ======================= Arch Coal, Inc. page 26. - --------------------------------------------------------------------------------

Adjusted income from operations in 2000 is comparable to 1999. Additional items affecting 2000 include an increase in income from operations resulting primarily from ongoing improved performance at several of the Company's mines, caused in part by the Company's continued focus on reducing costs and improving productivity. Income from operations also improved as a result of improved performance and production at the Company's Black Thunder mine and reduced costs in the current year resulting from the closure of the Dal-Tex operation in July 1999. The Dal-Tex complex incurred production shortfalls, deterioration of mining conditions and resulting lower income contributions prior to its closing on July 23, 1999. Income from operations was negatively affected by increased fuel costs in 2000 of over $1.0 million per month compared to 1999. Income from operations declined at the Company's Mingo Logan longwall operation (Mountaineer mine), where, despite the contribution of $39.3 million of income from operations, results were below the $46.6 million of income from operations for 1999. The decrease was primarily caused by depressed coal prices, generally less favorable mining conditions and increased mine development expenses associated with the start-up of operations in the Alma seam in preparation for moving longwall equipment into the newly developed seam in early 2001. Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased $7.5 million from 1999. The decrease was attributable to cost savings resulting from the restructuring of the Company's administrative workforce that occurred during the fourth quarter of 1999. Income Taxes. The Company's effective tax rate is sensitive to changes in annual profitability and percentage depletion. During the fourth quarter of 1999, the Company determined that as it relates to future income taxes, the Company did not anticipate recognizing all of its alternative minimum tax credit carryforwards in the future and only expected to recognize part of the benefit of its deferred tax asset at the alternative minimum tax rate of approximately 24%. Adjusted EBITDA. Adjusted EBITDA was $315.2 million for the year ended December 31, 2000 compared to $325.9 million for the prior year. The decrease in adjusted EBITDA was primarily attributable to the continued negative impact of the idling at the West Elk mine (including insurance recoveries) and lower operating profit at the Mingo Logan Mountaineer mine as described above. This was partially offset by improved performance at the Company's Black Thunder mine. Outlook West Elk Mine. The Company's West Elk mine encountered higher-than-expected methane levels following the relocation of its longwall mining system to the eastern section of the mine in late February 2001. The higher methane levels led to a reduction of planned shipments from the mine. The mine's performance has steadily improved as the mine has implemented a series of methane control procedures. The Company is hopeful that the mine will operate at breakeven or profitable levels during 2002. However, if the Company is unable to continue to adequately control methane levels at the mine, it may be forced to continue to operate the mine at lower levels of production than planned. West Virginia Operations. On October 20, 1999, the U.S. District Court for the Southern District of West Virginia permanently enjoined the West Virginia Department of Environmental Protection (DEP) from issuing any permits that authorize the construction of valley fills as part of coal mining operations. The West Virginia DEP complied with the injunction by issuing an order banning the issuance of permits for the construction of nearly all new valley fills and the expansion of nearly all existing valley fills. The district court then granted a stay of its injunction, pending the outcome of an appeal of the court's decision filed by the West Virginia DEP with the U.S. Court of Appeals for the Fourth Circuit. On April 24, 2001, the Court of Appeals vacated the judgment of the district court with respect to the injunction, and in January 2002, the United States Supreme Court declined to hear an appeal of the Court of Appeal's decision. 2001 Annual Report page 27. - --------------------------------------------------------------------------------

The injunction discussed above was entered as part of the litigation that caused a delay in obtaining mining permits for the Company's Dal-Tex operation described under "Contingencies-Legal Contingencies-Dal-Tex Litigation." As a result of the delay, the Company idled its Dal-Tex mining operation on July 23, 1999. If all necessary permits are obtained, the Company may reopen the mine subject to existing market conditions at the time. Previously, the Company had disclosed that longwall mineable reserves at Mingo Logan were likely to be exhausted during 2002. As a result of improvements to the mine plan, the mine is not expected to exhaust its longwall mineable reserves until 2004. During the second quarter of 2001, the Company's Samples surface mine in southern West Virginia encountered a larger-than-expected sandstone intrusion. The intrusion has resulted in the thinning of the principal coal seam in the ridge that the mine is currently mining. The thinning of the seam has reduced recoverable coal and driven up mining costs on a per-ton basis. The Company expects the Samples operation to be adversely affected by the sandstone intrusion through the first quarter of 2002. In early 2002, the Samples mine began development work on a new reserve area with more favorable geology. The Company expects the Samples mine to return to profitability during the second quarter of 2002. Low-Sulfur Coal Producer. The Company continues to believe that it is well positioned to capitalize on the continuing growth in demand for low-sulfur coal to produce electricity. One hundred percent of the Company's current coal production and approximately 90% of its reserves are low in sulfur. In fact, approximately 66% of the Company's coal reserves are compliance quality, which means that they meet Phase II standards of the Clean Air Act without application of expensive scrubbing technology. With Phase II now in effect, compliance coal has captured a growing share of United States coal demand and commands a higher price in the marketplace than high-sulfur coal. Chief Objectives. The Company continues to focus on realizing the potential of its assets and to maximize stockholder value. Its first financial objective in recent quarters has been to aggressively reduce debt and strengthen its balance sheet. For the year ended December 31, 2001, the Company reduced its total debt by $376.9 million principally through the use of proceeds raised in the February and May 2001 equity offerings described in the "Liquidity and Capital Resources" section below. In total, the Company has paid down approximately $600 million in debt since December 31, 1998. The Company's debt-to-capitalization ratio, which was 84% at December 31, 2000, improved to 58% at December 31, 2001. In addition to continuing its efforts to pay down, restructure and diversify its remaining debt, the Company will focus on taking steps designed to improve earnings, strengthen cash generation, improve productivity and reduce costs at its large-scale mines, while building on its leading position in its target coal-producing basins, the Powder River Basin and the Central Appalachian Basin. Liquidity and Capital Resources The following is a summary of cash provided by or used in each of the indicated types of activities during the past three years: Year ended December 31 (in thousands) 2001 2000 1999 Cash provided by (used in): Operating activities $ 145,661 $ 135,772 $ 279,963 Investing activities (129,209) (107,496) (84,358) Financing activities (15,590) (25,531) (219,736) Arch Coal, Inc. page 28. - --------------------------------------------------------------------------------

Cash provided by operating activities increased in 2001 compared to 2000 due primarily to improved operating performance in 2001. Increased distributions from the Company's investment in Canyon Fuel also positively affected cash provided by operating activities. These increases were partially offset by increased working capital requirements in 2001 compared to 2000. Cash provided by operating activities decreased in 2000 compared to 1999 due to a decrease in cash provided from equity investments and reduced coal sales, along with increased costs resulting from the temporary idling of the West Elk mine and increased fuel costs. Cash used in investing activities during 2001 increased compared to 2000 due primarily to higher capital expenditures. Cash used in investing activities increased in 2000 compared to 1999 primarily as a result of the Company making the second of five annual $31.6 million payments under the Thundercloud federal lease, which is part of the Black Thunder mine in Wyoming. The first payment was made at the time of the acquisition of the lease in 1998, and the third payment was made during 2001. The remaining two payments are due each January of the years 2002 and 2003. Cash used in financing activities during 2001 reflects the cash generated by the February 2001 and May 2001 issuances of common stock (described below) resulting in proceeds of $372.2 million, the pay-down of $376.9 million of debt and the repurchase of the Company's common stock at a cost of $5.0 million. Cash used in financing activities in 2000 reflects reduced debt payments as compared to 1999. In addition, the Company entered into a sale and leaseback of certain equipment during 2000 which resulted in net proceeds of $13.4 million. Dividend payments decreased $8.8 million in 2000 as compared to 1999, resulting from a decrease in shares outstanding and a reduction in the quarterly dividend from 11.5 cents per share to 5.75 cents per share. The dividend reduction is attributable to the Company's goal to aggressively pay down debt. On February 22, 2001, the Company completed a public offering of 9,927,765 shares of common stock, including the remaining 4,756,968 shares held by its then largest stockholder, Ashland Inc., and 5,170,797 primary and treasury shares issued directly by the Company. Proceeds realized from the transaction, which totaled $92.9 million net of the underwriters' discount and expenses, were used to pay down debt. On April 12, 2001, the Company filed a Universal Shelf Registration Statement on Form S-3 with the Securities and Exchange Commission. The Universal Shelf allows the Company to offer, from time to time, an aggregate of up to $750 million in debt securities, preferred stock, depositary shares, common stock and related rights and warrants. On May 8, 2001, the Company utilized the shelf registration and completed a public offering of 8,500,000 primary shares of common stock. On May 16, 2001, the underwriters involved in the offering purchased an additional 424,200 shares pursuant to an over-allotment option granted by the Company in connection with the May 8, 2001 offering. The proceeds realized from these transactions after the underwriting discount and expenses were $279.3 million. The proceeds were used to retire the Company's term loan, with the remainder reducing the borrowings under the Company's revolving credit facility. On September 14, 2001, the Company's Board of Directors approved a stock repurchase plan, under which the Company may repurchase up to 6.0 million of its shares of common stock from time to time. Through December 31, 2001, the Company repurchased 357,200 shares of its common stock for $5.0 million pursuant to the plan at an average purchase price of $14.13 per share. The repurchased shares are being held in the Company's treasury. Future repurchases under the plan will be made at management's discretion and will depend on market conditions and other factors. The Company generally satisfies its working capital requirements and funds its capital expenditures and debt-service obligations with cash generated from operations. The Company believes that cash generated from operations and its borrowing capacity will be sufficient to meet its working capital requirements and anticipated capital expenditures for at least the next several years. The Company's ability to fund planned capital expenditures, to make acquisitions and to pay 2001 Annual Report page 29. - --------------------------------------------------------------------------------

dividends will depend upon its future operating performance, which will be affected by prevailing economic conditions in the coal industry and financial, business and other factors, some of which are beyond the Company's control. Expenditures for property, plant and equipment were $123.4 million, $115.1 million and $98.7 million for 2001, 2000 and 1999, 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. At December 31, 2001, the Company had $35.7 million in letters of credit outstanding which, when combined with outstanding borrowing under the revolver, allowed for $431.3 million of additional borrowings under the revolving credit facility. Financial covenants contained in the Company's credit facilities consist of a maximum leverage ratio, a maximum fixed-charge coverage ratio and a minimum net-worth test. The leverage ratio requires that the Company not permit the ratio of total indebtedness at the end of any calendar quarter to adjusted EBITDA for the four quarters then ended to exceed a specified amount. The fixed-charge coverage ratio requires that the Company not permit the ratio of the Company's adjusted EBITDA plus lease expense to interest expense plus lease expense for the four quarters then ended to be less than a specified amount. The net-worth test requires that the Company not permit its net worth to be less than a specified amount plus 50% of cumulative net income. In addition, the covenants require the pledging of assets to collateralize the Company's revolving credit facility. The assets pledged include equity interests in wholly owned subsidiaries, certain real property interests, accounts receivable and inventory of the Company. The Company was in compliance with these financial covenants at December 31, 2001. At December 31, 2001, debt amounted to $773.9 million, or 58% of capital employed, compared to $1.151 billion, or 84% of capital employed, at December 31, 2000. Based on the current level of consolidated indebtedness and prevailing interest rates, debt-service obligations, which include the current maturities of debt and interest expense for 2002, are estimated to be $67.0 million. The Company periodically establishes uncommitted lines of credit with banks. These agreements generally provide for short-term borrowings at market rates. At December 31, 2001, there were $20.0 million of such agreements in effect, of which $13.5 million were outstanding. The Company has begun to arrange a refinancing of its revolving credit facility and of Arch Western's $675 million term loan. The Company expects the terms and conditions of the new facilities to be generally similar to the existing credit facilities and to complete the financing prior to the end of the second quarter of 2002. The Company is exposed to market risk associated with interest rates. At December 31, 2001, after taking into consideration interest-rate swap agreements, debt included $343.5 million of floating-rate debt for which the rate of interest is, at the Company's option, the PNC Bank base rate or a rate based on LIBOR and current market rates for bank lines of credit. To manage this exposure, the Company enters into interest-rate swap agreements to modify the interest-rate characteristics of outstanding Company debt. At December 31, 2001, the Company had interest-rate swap agreements having a total notional value of $425.0 million. 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 6.89% (before the credit spread over LIBOR) and receives a weighted-average variable rate based upon 30-day and 90-day LIBOR. The Company accrues amounts to be paid or received under interest-rate swap agreements over the lives of the agreements. These amounts are recognized as adjustments to interest expense over the lives of the agreements, thereby adjusting the effective interest rate on the Company's debt. Gains and losses on terminations of interest-rate swap agreements are deferred on the balance sheet (in other long-term liabilities) and amortized as an adjustment to interest expense over the original term of the terminated swap agreement as if it were still in place. The remaining terms of the swap agreements at December 31, 2001, ranged from eight to 42 months. All instruments are entered into for other than trading purposes. Arch Coal, Inc. page 30. - --------------------------------------------------------------------------------

The Company is also exposed to commodity price risk related to its purchase of diesel fuel. The Company enters into heating oil swaps to substantially eliminate volatility in the price of diesel fuel purchased 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 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 the Company's financial instruments to selected changes in market rates and prices. The range of changes reflects the Company's 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 the consolidated financial statements. Changes in interest rates have different impacts on the fixed-rate and variable-rate portions of the Company's debt portfolio. A change in interest rates on the fixed portion of the 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 the Company's debt portfolio assumes an instantaneous 100-basis-point move in interest rates from their levels at December 31, 2001, with all other variables held constant. A 100-basis-point decrease in market interest rates would result in a $7.2 million increase in the fair value of the fixed portion of the debt at December 31, 2001. Based on the variable-rate debt included in the Company's debt portfolio as of December 31, 2001, after considering the effect of the swap agreements, a 100-basis-point increase in interest rates would result in an annualized additional $3.4 million of interest expense incurred based on December 31, 2001 debt levels. At December 31, 2001 a $.05 per gallon decrease in the price of heating oil would result in a $1.3 million increase in the fair value of the financial position of the heating oil swap agreement. Contingencies Reclamation The federal Surface Mining Control and Reclamation Act of 1977 ("SMCRA") 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 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 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 liabilities are based upon permit requirements and require various estimates and assumptions, principally associated with costs and productivities. The Company reviews its entire environmental liability periodically and makes necessary adjustments, including permit changes and revisions to costs and productivities to reflect current experience. The Company's management believes it is making adequate provisions for all expected reclamation and other associated costs. 2001 Annual Report page 31. - --------------------------------------------------------------------------------

Legal Contingencies The Company is a party to numerous claims and lawsuits with respect to various matters, including those discussed below. The Company provides 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 the consolidated financial condition, results of operations or liquidity of the Company. Dal-Tex Litigation. A federal court injunction that prohibited the West Virginia Department of Environmental Protection ("DEP") from issuing permits for the Company's Dal-Tex mine to use valley fill mining techniques resulted in the shutdown of this mine in July 1999. A subsequent order prohibited the construction or expansion of valley fills in West Virginia. Valley fills are created by mountaintop mining and other techniques used in Central Appalachia, and involve the creation of large, engineered works into which excess earth and rock extracted during surface mining are placed. The plaintiffs in the litigation allege, among other things, that the construction of valley fills violates a regulation arising from SMCRA that the plaintiffs allege prohibits placing overburden or other obstructions in stream channels. The Company appealed the order specific to its Dal-Tex operations, and the Company, the West Virginia DEP and other interested parties appealed the broader order concerning valley fills. On April 24, 2001, the United States Court of Appeals for the Fourth Circuit vacated the judgment of the district court with respect to the injunction that prohibited the West Virginia DEP from issuing permits to use valley fill mining techniques. The plaintiffs appealed the decision of the Fourth Circuit to the United States Supreme Court, which declined to hear the appeal in January 2002. Because it is not financially viable for coal producers to operate some mining properties without valley fills, if state court remedies similar to those obtained in the federal district court are available to the plaintiffs, the Company may be forced to close all or a portion of its mining operations in West Virginia, to the extent those operations are dependent on the use of valley fills. A settlement agreement entered into between the parties will require the preparation of an environmental impact statement ("EIS") prior to the issuance of permits for the construction of valley fills. The preparation of these statements is time-consuming and is sometimes the subject of litigation. As a result, even though the district court decision has been overturned, the Company cannot reopen the Dal-Tex mine until the EIS is completed and all necessary permits are obtained. At that time, the decision to commence mining operations will be subject to then-existing market conditions. Cumulative Hydrologic Impact Assessment ("CHIA") Litigation. On January 20, 2000, two environmental organizations, the Ohio Valley Environmental Coalition and the Hominy Creek Watershed Association, filed suit against the West Virginia DEP in U.S. District Court in Huntington, West Virginia. In addition to allegations that the West Virginia DEP violated state law and provisions of the Clean Water Act, the plaintiffs allege that the West Virginia DEP's issuance of permits for surface and underground coal mining has violated certain non-discretionary duties mandated by SMCRA. Specifically, the plaintiffs allege that the West Virginia DEP has failed to require coal operators seeking permits to conduct water monitoring to verify stream flows and ascertain water quality, to always include certain water quality information in their permit applications and to analyze the probable hydrologic consequences of their operations. The plaintiffs also allege that the West Virginia DEP has failed to analyze the cumulative hydrologic impact of mining operations on specific watersheds. The plaintiffs sought an injunction to prohibit the West Virginia DEP from issuing any new permits which fail to comply with all of the elements identified in their complaint. The complaint identified, and sought to enjoin, three pending permits sought by the Company in connection with its Mingo Logan operations in order to continue existing surface mining operations at the Phoenix reserve. On January 15, 2001, the West Virginia DEP notified the plaintiffs that the Company had completed all steps necessary to obtain the permits. On March 8, 2001, the Court denied the plaintiffs' motion for a preliminary injunction seeking to enjoin the DEP's decision to issue the permits. The Company subsequently received some of the permits necessary to continue operating the surface mine. If the plaintiffs ultimately prevail in this litigation, Arch Coal, Inc. page 32. - --------------------------------------------------------------------------------

the Company's ability to mine surface coal at Mingo Logan could be adversely affected, and depending upon the length of the suspension, the effect could be material. This matter does not affect Mingo Logan's existing permits related to its underground operations. Certain Trends and Uncertainties Substantial Leverage-Variable Interest Rate-Covenants As of December 31, 2001, the Company had outstanding consolidated indebtedness of $773.9 million, representing approximately 58% of the Company's capital employed. Despite making substantial progress in reducing debt, the Company continues to have significant debt-service obligations, and the terms of its credit agreements limit its flexibility and result in a number of limitations on the Company. The Company also has significant lease and royalty obligations. The Company's ability to satisfy debt service, lease and royalty obligations and to effect any refinancing of its indebtedness will depend upon future operating performance, which will be affected by prevailing economic conditions in the markets that the Company serves as well as financial, business and other factors, many of which are beyond the Company's control. The Company may be unable to generate sufficient cash flow from operations and future borrowings, or other financings may be unavailable in an amount sufficient to enable it to fund its debt service, lease and royalty payment obligations or its other liquidity needs. The Company's relative amount of debt and the terms of its credit agreements could have material consequences to its business, including, but not limited to: (i) making it more difficult to satisfy debt covenants and debt service, lease payment and other obligations; (ii) making it more difficult to pay quarterly dividends as the Company has in the past; (iii) increasing the Company's vulnerability to general adverse economic and industry conditions; (iv) limiting the Company's ability to obtain additional financing to fund future acquisitions, working capital, capital expenditures or other general corporate requirements; (v) reducing the availability of cash flows from operations to fund acquisitions, working capital, capital expenditures or other general corporate purposes; (vi) limiting the Company's flexibility in planning for, or reacting to, changes in the Company's business and the industry in which the Company competes; or (vii) placing the Company at a competitive disadvantage when compared to competitors with less relative amounts of debt. After taking into consideration the Company's interest-rate swaps which convert the Company's variable rate debt to fixed, approximately 45% of the Company's indebtedness bears interest at variable rates that are linked to short-term interest rates. If interest rates rise, the Company's costs relative to those obligations would also rise. Terms of the Company's credit facilities and leases contain financial and other covenants that create limitations on the Company's ability to, among other things, effect acquisitions or dispositions and borrow additional funds, and 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 under these agreements which, if not cured or waived, would enable the Company's lenders to declare amounts borrowed due and payable, or otherwise result in unanticipated costs. Losses The Company reported a net loss of $12.7 million for the year ended December 31, 2000. The losses in 2000 were primarily attributable to the temporary idling of the West Elk mine in Colorado following the detection of combustion-related gases in a portion of the mine. Because the coal mining industry is subject to significant regulatory oversight and due to 2001 Annual Report page 33. - --------------------------------------------------------------------------------

the possibility of adverse pricing trends or other industry trends beyond the Company's control, the Company may suffer losses in the future if legal and regulatory rulings, mine idlings and closures, adverse pricing trends or other factors affect the Company's ability to mine and sell coal profitably. Environmental and Regulatory Factors Federal, state and local governmental authorities regulate the coal mining industry on matters as diverse as employee health and safety, air quality standards, water pollution, groundwater quality and availability, plant and wildlife protection, the reclamation and restoration of mining properties, the discharge of materials into the environment and surface subsidence from underground mining. In addition, federal legislation mandates certain benefits for various retired coal miners represented by the United Mine Workers of America ("UMWA"). These regulations and legislation have had and will continue to have a significant effect on the Company's cost of production and competitive position. Future regulations, legislation or orders may also cause the Company's sales or profitability to decline by hindering its ability to continue its mining operations, by increasing its costs or by causing coal to become a less attractive fuel source. Permits. Mining companies must obtain numerous permits that strictly regulate environmental, 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 necessary for 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 that restricts the Company's ability to conduct its mining operation or to do so profitably. As indicated by the legal action involving the Company's Dal-Tex operation that is discussed in "Contingencies-Legal Contingencies-Dal-Tex Litigation" above, the regulatory environment in West Virginia is uncertain with respect to coal mining. No assurance can be made that the plaintiffs will not obtain similar relief in a state court action as that obtained in the U.S. District Court action. In such event, there could be a material adverse effect on the Company's financial condition or results of operations. New Environmental Regulations. Several new environmental regulations require a reduction in nitrogen oxide ("NOx") emissions generated by coal-fired electric generating plants. Substantially all of the Company's revenues from sales of coal in 2001 were from sales to generators operating these types of plants. Enforcement actions against a number of these generators, which include some of our customers, and proposed legislation ultimately may require additional reductions in NOx emissions. The Environmental Protection Agency ("EPA") is also considering regulations that would require reductions in mercury emissions and further reduction in sulfur dioxide ("SO2") emissions from coal-fired electric generating plants. To comply with these regulations and enforcement actions, these generators may choose to switch to other fuels that generate less of these emissions, such as natural gas or oil. Kyoto Protocol. On December 11, 1997, the U.S. government representatives at the climate change negotiations in Kyoto, Japan, agreed to reduce U.S. emissions of greenhouse gases, including carbon dioxide and other gas emissions that are believed by some scientists to be trapping heat in the atmosphere and warming the earth's climate. The U.S. adoption of the requirements of the Kyoto Protocol is subject to conditions, which may not occur and is also subject to the protocol's ratification by the U.S. Senate. The U.S. Senate has indicated that it will not ratify an agreement unless certain conditions, not currently provided for in the Kyoto Protocol, are met. In addition, President Bush has stated that he does not support the Kyoto Protocol as written and has recently submitted an alternate proposal to reduce U.S. emissions of greenhouse gases. At present, it is not possible to predict whether either the Kyoto protocol or President Bush's proposal will attain the force of law in the United States or what the resulting impact would be on the Company. Arch Coal, Inc. page 34. - --------------------------------------------------------------------------------

Customers. In July 1997, the EPA proposed that 22 eastern states, including states in which many of the Company's customers are located, make substantial reductions in NOx emissions. The EPA expects the states to achieve these reductions by requiring power plants to reduce their NOx emissions to a level of 0.15 pounds of NOx per million Btu's of energy consumed. Many of the states sued the EPA in the U.S. Court of Appeals for the District of Columbia Circuit to challenge the new standard. In March 2000, the court upheld the standard and set a May 2004 deadline for compliance with the new rules. The states appealed to the U.S. Supreme Court, and in March 2001, the Court declined to hear the appeal. To achieve the proposed reductions, power plants may be required to install reasonably available control technology and additional control measures. The installation of these measures would make it more costly to operate coal-fired utility power plants and, depending on the requirements of individual state implementation plans, could make coal a less attractive fuel alternative in the planning and building of utility power plants in the future. The EPA has also proposed the implementation of stricter ozone standards by 2003. If these standards are implemented, they could require some of the Company's customers to reduce NOx emissions, which are a precursor to ozone formation, or even prevent the construction of new facilities that contribute to the non-attainment of the new ozone standard. The U.S. Department of Justice, on behalf of the EPA, has filed a lawsuit against seven investor-owned utilities and brought an administrative action against one government-owned utility for alleged violations of the Clean Air Act. The EPA claims that over 30 of these utilities' power stations have failed to obtain permits required under the Clean Air Act for major improvements which have extended the useful service of the stations or increased their generating capacity. The Company supplies coal to seven of the eight utilities. It is impossible to predict the outcome of this legal action. Any outcome that adversely affects the Company's customers or makes coal a less attractive fuel source could, however, have an adverse effect on the Company's coal sales revenues and profitability. Competition and Excess Industry Capacity The coal industry is intensely competitive, primarily as a result of the existence of numerous producers in the coal-producing regions in which the Company operates, and a number of the Company's competitors have greater financial resources. The Company competes with several major coal producers in the Central Appalachian and Powder River Basin areas. The Company also competes with a number of smaller producers in those and other market regions. The Company is subject to the risk of reduced profitability as a result of excess industry capacity, which has occurred in the past and which results in reduced coal prices. Electric Industry Factors Demand for coal and the prices that the Company will be able to obtain for its coal are closely linked to coal consumption patterns of the domestic electric generation industry, which has accounted for approximately 90% of domestic coal consumption in recent years. These coal consumption patterns are influenced by factors beyond the Company's control, including the demand for electricity (which is dependent to a significant extent on summer and winter temperatures); government regulation; technological developments and the location, availability, quality and price of competing sources of coal; and the use of competing fuels such as natural gas, oil, nuclear, and hydroelectric power. Demand for the Company's low-sulfur coal and the prices that the Company 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 federal Clean Air Act requirements. Any reduction in the demand for the Company's coal by the domestic electric generation industry may cause a decline in profitability. 2001 Annual Report page 35. - --------------------------------------------------------------------------------

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. Deregulation may have a negative effect on the Company's profitability to the extent it causes the Company's customers to be more cost-sensitive. Reliance on and Terms of Long-Term Coal Supply Contracts During 2001, sales of coal under long-term contracts, which are contracts with a term greater than 12 months, accounted for 77% of the Company's total revenues. 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 its sales that are subject to these long-term agreements, the Company has less coal available with which to capitalize on stronger coal prices if and when they arise. In addition, because long-term contracts typically allow the customer to elect volume flexibility, the Company's 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, or the Company's exposure to market-based pricing may be increased should customers elect to purchase fewer tons. The increasingly short terms of sales contracts and the consequent absence of price-adjustment provisions in such contracts also make it more likely that inflation-related increases in mining costs during the contract term will not be recovered by the Company. Reserve Degradation and Depletion The Company's profitability depends substantially on its 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. The Company has in the past acquired, and in the future is likely to acquire, coal reserves for its mine portfolio from third parties. The Company may not be able to accurately assess the geological characteristics of any reserves that it acquires, which may adversely affect the profitability and financial condition of the Company. Exhaustion of reserves at particular mines can also have an adverse effect on operating results that is disproportionate to the percentage of overall production represented by such mines. Mingo Logan's Mountaineer mine is estimated to exhaust its longwall mineable reserves in 2004. The Mountaineer mine generated $36.7 million and $39.3 million of the Company's total operating income in the year ended December 31, 2001 and 2000, respectively. Potential Fluctuations in Operating Results-Factors Routinely Affecting Results of Operations The Company's 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 profitability. Weather conditions, equipment replacement or repair, fuel prices, 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 operating results. A prolonged disruption of production at any of the Company's principal mines, particularly its Mingo Logan operation in West Virginia, would result in a decrease, which could be material, in the Company's revenues and profitability. Other factors affecting the production and sale of the Company's coal that could result in decreases in its profitability include: (i) expiration or termination of, or sales price redeterminations or suspension of deliveries under, coal supply agreements; (ii) disruption or increases in the cost of transportation services; (iii) changes in laws or regulations, including permitting requirements; (iv) litigation; (v) work stoppages or other labor difficulties; (vi) mine worker vacation schedules and related maintenance activities; and (vii) changes in coal market and general economic conditions. Arch Coal, Inc. page 36. - --------------------------------------------------------------------------------

Decreases in the Company's profitability as a result of the factors described above could adversely impact quarterly or annual results materially. Any such adverse impact on the Company's operating results could cause its stock price to decline substantially, particularly if the results are below research analyst or investor expectations. Transportation The coal industry depends on rail, trucking and barge transportation to deliver shipments of coal to customers, and transportation costs are a significant component of the total cost of supplying coal. Disruption of these transportation services could temporarily impair the Company's ability to supply coal to its customers and thus adversely affect the Company's business and operating results. Increases in transportation costs, or changes in such costs relative to transportation costs for coal produced by its competitors or of other fuels, could have an adverse effect on the Company's business and results of operations. Reserves-Title There are numerous uncertainties inherent in estimating quantities of recoverable reserves, including many factors beyond the control of the Company. Estimates of economically recoverable coal reserves and net cash flows necessarily depend upon a number of variable factors and assumptions. These factors and assumptions include geological and mining conditions which may not be fully identified by available exploration data or 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 coal prices, operating costs, severance and excise taxes, development costs and reclamation costs, all of which may cause estimates to vary considerably from actual results. For these reasons, estimates of the economically recoverable quantities attributable to any particular group of properties or classifications of such reserves based on risk of recovery and estimates of net cash flows expected therefrom that are 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 the Company's reserves, may vary from estimates, and such variances may be material. These estimates thus may not accurately reflect the Company's actual reserves. A significant part of the Company's mining operations are conducted on properties leased by the Company. The loss of any lease could adversely affect the Company's ability to develop the associated reserves. Because title to most of the Company's leased properties and mineral rights is not usually verified until a commitment is made by the Company to develop a property, which may not occur until after the Company has obtained necessary permits and completed exploration of the property, the Company's right to mine certain reserves may be adversely affected if defects in title or boundaries exist. In order to obtain leases or mining contracts to conduct mining operations on property where these defects exist, the Company has had to, and may in the future have to, incur unanticipated costs. In addition, the Company may not be able to successfully negotiate new leases or mining contracts for properties containing additional reserves, or maintain its leasehold interests in properties on which mining operations are not commenced, during the term of the lease. Certain Contractual Arrangements The Company's affiliate, Arch Western Resources, LLC, is the owner of Company reserves and mining facilities in the western United States. The agreement under which Arch Western was formed provides that a subsidiary of the Company, as the managing member of Arch Western, generally has exclusive power and authority to conduct, manage and control the 2001 Annual Report page 37. - --------------------------------------------------------------------------------

business of Arch Western. However, consent of BP Amoco, the other member of Arch Western, would generally be required in the event that Arch Western proposes to make a distribution, incur indebtedness, sell properties or merge or consolidate with any other entity if, at such time, Arch Western has a debt rating less favorable than specified ratings with Moody's Investors Service or Standard & Poor's or fails to meet specified indebtedness and interest ratios. In connection with the Company's June 1, 1998 acquisition of Atlantic Richfield Company's ("ARCO") coal operations, the Company entered into an agreement under which it agreed to indemnify ARCO 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 certain properties of Arch Western, the repurchase of certain equity interests in Arch Western by Arch Western or the reduction under certain circumstances of indebtedness incurred by Arch Western in connection with the acquisition. ARCO was acquired by BP Amoco in 2000. Depending on the time at which any such indemnification obligation were to arise, it could impact the Company's profitability for the period in which it arises. The membership interests in Canyon Fuel, which operates three coal mines in Utah, are owned 65% by Arch Western and 35% by a subsidiary of ITOCHU Corporation of Japan. The agreement that 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 the Company's ability to make these decisions. 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; the 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; the entering into of leases; and the selection and removal of officers. The Canyon Fuel agreement also contains various restrictions of the transfer of membership interests in Canyon Fuel. The Company's Amended and Restated Certificate of Incorporation requires the affirmative vote of the holders of at least two-thirds of outstanding common stock voting thereon to approve a merger or consolidation and certain other fundamental actions involving or affecting control of the Company. The Company's Bylaws require the affirmative vote of at least two-thirds of the members of the Board of Directors of the Company in order to declare dividends and to authorize certain other actions. Critical Accounting Policies Throughout Management's Discussion and Analysis, the Company has described critical accounting policies and sensitive judgment areas that impact the financial statements. Critical accounting policies described elsewhere in Management's Discussion and Analysis include: -- income taxes -- reclamation, and -- contingencies In addition to those described elsewhere in this document, the following other critical accounting policies are described. 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 Arch Coal, Inc. page 38. - --------------------------------------------------------------------------------

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 workers' compensation benefits for traumatic injuries which are accrued as injuries are incurred. Employee Beneft 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 accounts for its 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. 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 UMWA is not contributory. The Company's current funding policy is to fund the cost of all postretirement medical/life insurance benefits as they are paid. The Company accounts for its 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. 2001 Annual Report page 39. - --------------------------------------------------------------------------------

Report of Independent Auditors - -------------------------------------------------------------------------------- To the Stockholders and Board of Directors Arch Coal, Inc. We have audited the accompanying consolidated balance sheets of Arch Coal, Inc. and subsidiaries as of December 31, 2001 and 2000 and the related consolidated statements of operations, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2001. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above (appearing on pages 42 to 65 of this annual report) present fairly, in all material respects, the consolidated financial position of Arch Coal, Inc. and subsidiaries at December 31, 2001 and 2000, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2001, in conformity with accounting principles generally accepted in the United States. As discussed in Note 1 to the consolidated financial statements, the Company changed its method of accounting for derivatives and hedging activities effective January 1, 2001. As discussed in Note 4 to the consolidated financial statements, in 1999, the Company changed its method of accounting for depreciation of its preparation plants and loadouts.

Report of Management - -------------------------------------------------------------------------------- The management of Arch Coal, Inc. is responsible for the preparation of the consolidated financial statements and related financial information in this annual report. The financial statements are prepared in accordance with accounting principles generally accepted in the United States and necessarily include some amounts that are based on management's informed estimates and judgments, with appropriate consideration given to materiality. The Company maintains a system of internal accounting controls designed to provide reasonable assurance that financial records are reliable for purposes of preparing financial statements and that assets are properly accounted for and safeguarded. The concept of reasonable assurance is based on the recognition that the cost of a system of internal accounting controls should not exceed the value of the benefits derived. The Company has a professional staff of internal auditors who monitor compliance with and assess the effectiveness of the system of internal accounting controls. The Audit Committee of the Board of Directors, composed of directors who are free from relationships that may impair their independence from Arch Coal, Inc., meets regularly with management, the internal auditors, and the independent auditors to discuss matters relating to financial reporting, internal accounting control, and the nature, extent and results of the audit effort. The independent auditors and internal auditors have full and free access to the Audit Committee, with and without management present. /s/ Steven F. Leer Steven F.

Notes to Consolidated Financial Statements - -------------------------------------------------------------------------------- 1. Accounting Policies Principles of Consolidation The consolidated financial statements include the accounts of Arch Coal, Inc. and its subsidiaries ("the Company"), which operate in the coal mining industry. The Company operates one reportable segment: the production of steam and metallurgical coal from surface and deep mines throughout the United States, for sale to utility, industrial and export markets. The Company's mines are primarily located in the Central Appalachian and western regions of the United States. All subsidiaries (except as noted below) are wholly owned. Significant intercompany transactions and accounts have been eliminated in consolidation. The Company's Wyoming, Colorado and Utah coal operations are included in a joint venture named Arch Western Resources, LLC ("Arch Western"). Arch Western is 99% owned by the Company and 1% owned by BP Amoco. The Company also acts as the managing member of Arch Western. The membership interests in the Utah coal operations, or Canyon Fuel, LLC ("Canyon Fuel"), are owned 65% by Arch Western 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 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 a 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 5.) The Company's 17.5% partnership interest in Dominion Terminal Associates is accounted for on the equity method in the consolidated balance sheets. Allocable costs of the partnership for coal loading and storage are included in other expenses in the consolidated statements of operations. 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. Arch Coal, Inc. page 46. - --------------------------------------------------------------------------------

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 (in thousands) 2001 2000 Coal $ 28,165 $ 21,185 Supplies, net of allowance 31,968 26,745 ------------------- $ 60,133 $ 47,930 =================== 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 $16.6 million and $19.8 million at December 31, 2001 and 2000, 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 $198.6 million and $171.2 million at December 31, 2001 and 2000, 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. 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. These costs are amortized using the units-of-production method over the estimated recoverable reserves that are associated with the property being benefited. At December 31, 2001, all mineral reserves of the Company that are capitalized are being amortized on the units-of-production method through Company operations or through sublease transactions (for which the Company receives royalty revenue) except for a block of 197 million tons located adjacent to its Hobet 21 operation. The current value associated with this property is $178.7 million, which the Company plans to recover via mining operations in the future. Plant and equipment are depreciated principally on the straight-line method over the estimated useful lives of the assets, which range from three to 30 years except for preparation plants and loadouts. Effective January 1, 1999, preparation plants 2001 Annual Report page 47. - --------------------------------------------------------------------------------

and loadouts are depreciated using the units-of-production method over the estimated recoverable reserves, subject to a minimum level of depreciation (see additional discussion in Note 4, "Change in Accounting Method"). Leased property meeting certain criteria is capitalized and the present value of the related lease payments is recorded as a liability. Amortization of capitalized leased assets is computed on the straight-line method over the term of the lease. 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 Derivative financial instruments are utilized by the Company in the management of its diesel fuel and interest rate exposures. The Company does not use derivative financial instruments for trading or speculative purposes. The Company adopted FAS 133, Accounting for Derivative Instruments and Hedging Activities, 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 qualify 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 interest-rate swap agreements and heating oil swap agreements are deferred on the balance sheets (in other long-term liabilities) and amortized as an adjustment to interest expense or diesel fuel expense over the remaining original term of the terminated swap agreement. When the Company determines that the hedged transaction is no longer likely to occur, amounts remaining in other comprehensive income are reclassified to earnings. 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. During 2001, the Company entered 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. Arch Coal, Inc. page 48. - --------------------------------------------------------------------------------

Income Taxes Deferred income taxes are based on temporary differences between the financial statement and tax basis of assets and liabilities existing at each balance sheet date using enacted tax rates for years during which taxes are expected to be paid or recovered. Stock-Based Compensation These financial statements include the disclosure requirements of FAS 123, Accounting for Stock-Based Compensation. With respect to accounting for its stock options, as permitted under FAS 123, the Company has retained the intrinsic value method prescribed by Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees, and related Interpretations. Accounting Development In June 2001, the Financial Accounting Standards Board issued FAS 143, Accounting for Asset Retirement Obligations, which is effective for fiscal years beginning after June 15, 2002. 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 should be capitalized as part of the related long-lived asset and allocated to expense over the useful life of the asset. The Company will adopt FAS 143 on January 1, 2003. Due to the significant number of mines that the Company operates throughout the United States and the extensive amount of information that must be reviewed and estimates that must be made to assess the effects of the statement, the expected impact of adoption of FAS 143 on the Company's financial position or results of operations has not yet been determined. 2. Changes in Estimates and Other Non-recurring Revenues and Expenses The Company's operating results for the year ended December 31, 2001 reflect a $9.4 million insurance settlement as part of the Company's coverage under its property and business interruption policy. The insurance settlement represents the final 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. The results for the year ended December 31, 2000 reflect $31.0 million in partial insurance settlements associated with this event. During the year ended December 31, 2001, the Company reduced its reclamation liability resulting in a pre-tax gain of $7.5 million, of which $5.6 million was the result of permit revisions and the ultimate sale of the surface rights at its idle mine properties in Illinois and $1.9 million was a result of estimate changes. Also, as a result of permit revisions at the idle mine properties in Illinois during the year ended December 31, 2000, the Company reduced its reclamation liability, resulting in a pre-tax gain of $7.8 million. During the year ended December 31, 2001, as a result of progress in processing claims associated with the recovery of certain previously paid excise taxes on export sales, the Company recognized a pre-tax gain of $4.6 million. Of the $4.6 million recognized, $3.1 million represents the interest component of the claim and was recorded as interest income. The gain stems from an IRS notice during the second quarter of 2000 outlining the procedures for obtaining tax refunds on black lung excise taxes paid by the industry on export sales. The notice was the result of a 1998 federal district court decision that found such taxes to be unconstitutional. The Company recorded $12.7 million of pre-tax income related to these excise tax recoveries during the year ended December 31, 2000. During the year ended December 31, 2001, the Company received a state tax credit covering prior periods that resulted in a pre-tax gain of $7.4 million. As a result of several litigation settlements, the Company increased its litigation reserve, resulting in a pre-tax decrease in income of $5.6 million. The Company also increased its stock-based benefit program accruals for awards that met minimum performance levels to qualify for a payout. This resulted in a decrease in pre-tax 2001 Annual Report page 49. - --------------------------------------------------------------------------------

income of $4.1 million during the year ended December 31, 2001. During 2001, Canyon Fuel, the Company's equity method investment, 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. The Company recognized a $13.5 million pre-tax gain in 2001 and a $12.1 million pre-tax gain in 2000 primarily as a result of selling land. In 2000, as a result of adjustments to employee postretirement medical benefits, the Company was able to recognize $9.8 million of pre-tax curtailment gains resulting from previously unrecognized postretirement benefit changes which occurred from plan amendments in previous years. The Company also settled certain workers' compensation liabilities during 2000 with the state of West Virginia, resulting in pre-tax gains of $21.8 million. This was partially offset in 2000 by adjustments to other workers' compensation liabilities resulting from changes in estimates which caused increases to the liability of $13.5 million. During 1999, the Company determined that significant changes were necessary in the manner and extent in which certain Central Appalachia coal assets would be deployed. As a result of the planned changes in the deployment of its long-lived assets in the region and pursuant to FAS 121, Accounting for the Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of, the Company recorded a pre-tax, non-cash impairment charge at three mining operations and certain coal reserves with no future mining plans of $364.4 million (including $50.6 million relating to operating assets and $314.0 million relating to coal reserves). The estimated fair value for the three mining operations was based on anticipated future cash flows discounted at a rate commensurate with the risk involved. The estimated fair value for the coal reserves with no future mining plans was based upon the fair value of these properties to be derived from subleased operations. In addition, during 1999 the Company recorded pre-tax charges of $23.1 million related to the restructuring of its administrative workforce and the closure of several operations. The restructuring eliminated 81 administrative jobs and 161 jobs at the operations. Of the $23.1 million charge, $20.3 million was recorded in cost of coal sales, $2.3 million was recorded in selling, general and administrative expenses and $0.5 million was recorded in other expenses in the Company's consolidated statement of operations. Except for amounts attributable to retiree healthcare, approximating $1.5 million, the Company has utilized the balance of the charge through December 31, 2001. 3. Other Comprehensive Income Other comprehensive income items under FAS 130, Reporting Comprehensive Income, are transactions recorded in stockholders' equity during the year, excluding net income and transactions with stockholders. The Company adopted FAS 133 on January 1, 2001. In accordance with FAS 133, the Company recorded a cumulative effect of accounting change which is shown below. Following are the items included in other comprehensive income (loss) and the related tax effects including the adoption of FAS 133: Minimum Pension Financial Liability (in thousands) Derivatives Adjustments Loss Adoption (January 1, 2001) Pre-tax amount $ (7,910) $ - $ (7,910) Tax benefit 3,085 - 3,085 --------------------------------- Net amount (4,825) - (4,825) 2001 Pre-tax amount (21,562) (4,673) (26,235) Tax benefit 8,409 1,822 10,231 --------------------------------- Net amount (13,153) (2,851) (16,004) Total 2001 Pre-tax amount (29,472) (4,673) (34,145) Tax benefit 11,494 1,822 13,316 --------------------------------- Net amount $(17,978) $(2,851) $(20,829) ================================= Arch Coal, Inc. page 50. - --------------------------------------------------------------------------------

4. Change in Accounting Method Through December 31, 1998, plant and equipment had principally been depreciated on the straight-line method over the estimated useful lives of the assets. Effective January 1, 1999, depreciation on the Company's preparation plants and loadouts was computed using the units-of-production method, which is based upon units produced, subject to a minimum level of depreciation. As these are usage-based assets, whose economic lives are typically based and measured on coal throughput, the Company believes the units-of-production method is preferable to the method previously used, because the new method recognizes that depreciation of this equipment is related substantially to physical wear due to usage and also to the passage of time. This method, therefore, more appropriately matches production costs over the lives of the preparation plants and loadouts with coal sales revenue, and results in a more accurate allocation of the cost of the physical assets to the periods in which the assets are consumed. The cumulative effect of applying the new method for years prior to 1999 is an increase to income of $3.8 million net of tax ($6.3 million pre-tax), reported as a cumulative effect of accounting change in the consolidated statement of operations for the year ended December 31, 1999. 5.

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 2001 Annual Report page 51. - --------------------------------------------------------------------------------

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 is no impact of the charge on the Company's financial position. 6. Accrued Expenses Accrued expenses included in current liabilities consist of the following: December 31 (in thousands) 2001 2000 Payroll and related benefits $ 21,620 $ 22,500 Taxes other than income taxes 49,187 50,267 Postretirement benefits other than pension 22,526 16,629 Workers' compensation 9,907 10,438 Interest 5,676 13,078 Reclamation and mine closure 5,667 16,126 Other accrued expenses 19,479 23,265 --------------------- $ 134,062 $ 152,303 ===================== 7.

During 2000, the Company received notice from the IRS of their proposed adjustments for tax years 1995 and 1996. The Company paid $4.7 million during the first quarter of 2001, which was charged against previously recorded reserves to partially settle the audit, and continues to contest additional tax adjustments of $0.8 million with the IRS. During 1999, the Company settled an audit of the former Ashland Coal, Inc. returns for the years January 1995 through June 1997. A payment of $0.1 million was made in January 1999 in settlement of all issues. Management believes that the Company has adequately provided for any income taxes and interest which may ultimately be paid with respect to all open tax years. Significant components of the Company's deferred tax assets and liabilities that result from carryforwards and temporary differences between the financial statement basis and tax basis of assets and liabilities are summarized as follows: December 31 (in thousands) 2001 2000 Deferred tax assets: Postretirement benefits other than pensions $ 134,708 $ 136,268 Alternative minimum tax credit carryforward 88,508 80,017 Workers' compensation 30,643 30,301 Reclamation and mine closure 20,747 25,019 Net operating loss carryforwards 28,121 28,338 Plant and equipment 1,541 17,784 Advance royalties 20,020 15,976 Other comprehensive income 13,316 - Other 41,595 55,035 -------------------- Gross deferred tax assets 379,199 388,738 Valuation allowance (119,723) (117,860) -------------------- Total deferred tax assets 259,476 270,878 -------------------- Deferred tax liabilities: Leases 5,172 20,371 Coal supply agreements 3,804 19,796 Other 31,249 23,928 -------------------- Total deferred tax liabilities 40,225 64,095 -------------------- Net deferred tax asset 219,251 206,783 Less current asset 23,840 27,440 -------------------- Long-term deferred tax asset $ 195,411 $ 179,343 ==================== The Company has a net operating loss carryforward for regular income tax purposes of $28.1 million which will expire in the years 2008 to 2014. The Company has an alternative minimum tax credit carryforward of $88.5 million, which may carry forward indefinitely to offset future regular tax in excess of alternative minimum tax. The Company has recorded a valuation allowance for a portion of its deferred tax assets that management believes, more likely than not, will not be realized. These deferred tax assets include a portion of the alternative minimum tax credits and some of the deductible temporary differences that will likely not be realized at the maximum effective tax rate. Such valuation allowance consisted of the following components at December 31 on the years indicated: December 31 (in thousands) 2001 2000 Unrealized future deductible temporary differences $ 78,744 $ 85,372 Unutilized alternative minimum tax credits 40,979 32,488 ------------------- Valuation allowance at December 31 $119,723 $ 117,860 =================== 2001 Annual Report Page 53. - --------------------------------------------------------------------------------

8. Debt and Financing Arrangements Debt consists of the following: December 31 (in thousands) 2001 2000 Indebtedness to banks under lines of credit (weighted average rate at December 31, 2001 - 2.88%) $ 13,500 $ - Indebtedness to banks under revolving credit agreement, expiring May 31, 2003 (weighted average rate at December 31, 2001 - 2.87%; December 31, 2000 - 8.00%) 80,000 332,100 Variable rate fully amortizing term loan payable quarterly from July 1, 2001 through May 31, 2003 (weighted average rate at December 31, 2000 - 8.29%) - 135,000 Variable rate non-amortizing term loan due May 31, 2003 (weighted average rate at December 31, 2001 - 3.25%; December 31, 2000 - 8.03%) 675,000 675,000 Other 5,355 8,695 -------------------- 773,855 1,150,795 Less current portion 6,500 60,129 --------------------- Long-term debt $ 767,355 $1,090,666 ===================== The Company has two credit facilities: a $675.0 million non-amortizing term loan in the name of Arch Western and a revolving credit facility in the name of the Company. The rate of interest on borrowings under both of the credit facilities is based on LIBOR. The Arch Western loan is secured by Arch Western's membership interests in its subsidiaries. It is not guaranteed by the Company. The Company's credit facility initially included both a revolver and a fully amortizing term loan. In February and May 2001, the Company used proceeds from its public stock offerings (see Note 13) to retire its term loan, with the remainder reducing the then-outstanding borrowings under the revolver. Subsequent to such repayments, the Company's revolving credit agreement provides for borrowings of up to $547.0 million less any outstanding letters of credit. At December 31, 2001, the Company had $35.7 million in letters of credit outstanding which, when combined with outstanding borrowings under the revolver, allowed for $431.3 million of additional borrowings under the revolver. The Company also periodically establishes uncommitted lines of credit with banks. These agreements generally provide for short-term borrowings at market rates. At December 31, 2001, there were $20.0 million of such agreements in effect, of which $13.5 million was outstanding. Aggregate required maturities of debt are $5.1 million in 2002, $768.6 million in 2003, and $0.1 million thereafter. Terms of the Company's credit facilities and leases 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 require the Company to, among other things, maintain various financial ratios and comply with various other financial covenants. In addition, the covenants require the pledging of assets to collateralize the term loan and the Company's revolving credit facility. The assets pledged include equity interests in wholly-owned subsidiaries, certain real property interests, accounts receivable and inventory of the Company. 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 financial covenants at December 31, 2001. The Company enters into interest-rate swap agreements to modify the interest characteristics of the Company's outstanding debt. At December 31, 2001, the Company had interest-rate swap agreements having a total notional value of $425.0 million. 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 6.89% (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, 2001, the remaining terms of the swap agreements ranged from eight to 42 months. Arch Coal, Inc.

9. 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, 2001 and 2000, the fair values of these swaps are liabilities of $24.6 million and $7.9 million, respectively. Heating oil swaps: The fair values of heating oil swaps are based on quoted prices. At December 31, 2001, the fair value of these swaps is a liability of $2.7 million. 10. 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 workers' compensation benefits for traumatic injuries which are accrued as injuries are incurred. Workers' compensation costs (credits) include the following components: Year ended December 31 (in thousands) 2001 2000 1999 Self-insured black lung benefits: Service cost $ 1,090 $ 1,273 $ 1,671 Interest cost 2,777 3,620 3,522 Net amortization and deferral (1,537) (1,486) 327 ----------------------------- 2,330 3,407 5,520 Other workers' compensation benefits 12,221 6,942 13,241 ----------------------------- $14,551 $10,349 $18,761 ============================= Payments for workers' compensation were $14.5 million, $23.2 million and $20.1 million in the years ended December 31, 2001, 2000, and 1999, respectively. The actuarial assumptions used in the determination of black lung benefits included a discount rate of 7.50% as of December 31, 2001 (7.75% and 7.50% as of December 31, 2000 and 1999, respectively) and a black lung benefit cost escalation rate of 4% in each year. In 2000, the Company settled several of its mining operations' self-insured workers' compensation and black lung liabilities with the State of West Virginia, resulting in pre-tax gains of $21.8 million. This was partially offset in 2000 by adjustments to other workers' compensation liabilities resulting from changes in estimates which caused increases to the liability of $13.5 million. The net workers' compensation adjustment was a pre-tax gain of $8.3 million. 2001 Annual Report Page 55. - --------------------------------------------------------------------------------

Summarized below is information about the amounts recognized in the consolidated balance sheets for workers' compensation benefits: December 31 (in thousands) 2001 2000 Actuarial present value for self-insured black lung: Benefits contractually recoverable from others $ 1,942 $ 2,144 Benefits for Company employees 37,862 35,710 ------------------ Accumulated black lung benefit obligation 39,804 37,854 Unrecognized net gain 5,145 6,252 ------------------ 44,949 44,106 Traumatic and other workers' compensation 43,726 44,925 ----------------- Accrued workers' compensation 88,675 89,031 Less amount included in accrued expenses 9,907 10,438 ----------------- $78,768 $78,593 ================== Receivables related to benefits contractually recoverable from others of $1.9 million in 2001 and $2.1 million in 2000 are recorded in other long-term assets. 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 $10.8 million, $10.4 million and $12.9 million in 2001, 2000 and 1999, respectively, for current and final mine closure reclamation, excluding reclamation recosting adjustments identified below. Cash payments for final mine closure reclamation and current disturbances approximated $8.7 million, $18.2 million and $15.8 million for 2001, 2000 and 1999, 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. Adjustments included a net decrease in the liability of $7.5 million and $9.2 million in 2001 and 2000, respectively, and a net increase in the liability of $4.3 million in 1999. The Company's management believes it is making adequate provisions for all expected reclamation and other costs associated with mine closures. 12. 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. Arch Coal, Inc. Page 56 - --------------------------------------------------------------------------------

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 insurance benefits as they are paid. Summaries of the changes in the benefit obligations, plan assets (primarily listed stocks and debt securities) and funded status of the plans are as follows: Other Pension Benefits Postretirement Benefits ------------------------ ------------------------- (in thousands) 2001 2000 2001 2000 Change in Benefit Obligations Benefit obligations at January 1 $ 139,064 $ 131,783 $ 299,432 $ 330,846 Service cost 7,542 6,817 2,028 1,901 Interest cost 10,472 9,546 23,623 24,416 Benefits paid (10,390) (15,111) (22,846) (16,636) Plan amendments (11) 642 - (13,658) Other-primarily actuarial (gain) loss 8,956 5,387 35,568 (27,437) ------------------------------------------------------- Benefit obligations at December 31 $ 155,633 $ 139,064 $ 337,805 $ 299,432 ======================================================= Change in Plan Assets Value of plan assets at January 1 $ 138,864 $ 147,217 $ - $ - Actual return on plan assets (loss) (9,254) (2,915) - - Employer contributions 669 9,673 22,846 16,636 Benefits paid (10,390) (15,111) (22,846) (16,636) ------------------------------------------------------- Value of plan assets at December 31 $ 119,889 $ 138,864 $ - $ - ======================================================= Funded Status of the Plans Accumulated obligations less plan assets $ 35,744 $ 200 $ 337,805 $ 299,432 Unrecognized actuarial gain (loss) (14,743) 16,908 413 41,304 Unrecognized net transition asset 293 491 - - Unrecognized prior service cost 1,656 1,886 10,406 12,556 ------------------------------------------------------- Net liability recognized $ 22,950 $ 19,485 $ 348,624 $ 353,292 ======================================================= Balance Sheet Amounts Intangible asset (Other assets) $ (741) $ - $ - $ - Minimum pension liability adjustment (Other noncurrent liabilities) (2,758) - - - Accrued benefit liabilities 26,449 19,485 348,624 353,292 ------------------------------------------------------ Net liability recognized 22,950 19,485 348,624 353,292 Less current portion 411 198 22,526 16,629 ------------------------------------------------------ Long-term liability $ 22,539 $ 19,287 $326,098 $ 336,663 ====================================================== Other Postretirement Benefits The actuarial loss generated in 2001 resulted from: changes in demographic information, a reduction in the discount rate and changes in mine life assumptions. The reduction in the postretirement benefit obligation in 2000 associated with the $13.7 million plan amendment resulted from: the July 2000 amendment changing some of the cost-sharing provisions of the plan for salaried and non-union hourly participants; and an October 2000 plan amendment changing eligibility requirements to 10 years of service after reaching age 45 for salaried and non-union hourly participants. The latter plan change triggered a curtailment that resulted in the recognition of $9.8 million in previously unrecognized prior service gains. The $27.4 million actuarial gain in 2000 resulted from plan assumption changes. 2001 Annual Report page 57. - --------------------------------------------------------------------------------

Pension Benefits The actuarial loss in the 2001 and 2000 pension benefit obligation resulted from changes in plan assumptions. The decrease in funded status in year 2001 resulted from decreased earnings on plan assets during the year, which also contributed to the reduction in the unrecognized actuarial gain as compared to the prior year.

The health care cost trend rate assumption has a significant effect on the amounts reported. For example, increasing the assumed health care cost trend rate by one percentage point each year would increase the accumulated postretirement obligation as of December 31, 2001 by $41.9 million, or 12.4%, and the net periodic postretirement benefit cost for 2001 by $3.2 million, or 17.6%. Multi-Employer Pension and Benefit Plans Under the labor contract with the UMWA, the Company made no payments in 2001 and payments of $0.1 million and $0.2 million in 2000 and 1999, respectively, into a multi-employer defined benefit pension plan trust established for the benefit of union employees. Payments are based on hours worked and are expensed as hours are incurred. Under the Multi-Employer Pension Plan Amendments Act of 1980, a contributor to a multi-employer pension plan may be liable, under certain circumstances, for its proportionate share of the plan's unfunded vested benefits (withdrawal liability). At December 31, 2001, the Company has estimated its share of such amount to be $22.2 million. The Company is not aware of any circumstances which would require it to reflect its share of unfunded vested pension benefits in its financial statements. At December 31, 2001, approximately 19% of the Company's workforce was represented by the UMWA. In December 2001, a new UMWA collective bargaining agreement was approved, replacing the previous agreement, which was set to expire on December 31, 2002. The new agreement is effective from January 1, 2002 through December 31, 2006. Arch Coal, Inc. page 58. - --------------------------------------------------------------------------------

The Coal Industry Retiree Health Benefit Act of 1992 ("Benefit Act") provides for the funding of medical and death benefits for certain retired members of the UMWA through premiums to be paid by assigned operators (former employers), transfers of monies in 1993 and 1994 from an overfunded pension trust established for the benefit of retired UMWA members, and transfers from the Abandoned Mine Lands Fund (funded by a federal tax on coal production) commencing in 1995. The Company treats its obligation under the Benefit Act as a participation in a multi-employer plan and records expense as premiums are paid. The Company recorded $3.0 million in 2001, $3.3 million in 2000 and $2.7 million in 1999 in expense relative to premiums paid pursuant to the Benefit Act. 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 $8.1 million in 2001, $8.0 million in 2000 and $8.4 million in 1999. 13. Capital Stock On February 22, 2001, the Company completed a public offering of 9,927,765 shares of common stock, including the remaining 4,756,968 shares held by its then largest stockholder, Ashland Inc., and 5,170,797 primary and treasury shares issued directly by the Company. The proceeds realized by the Company from the transaction of $92.9 million after the underwriters' discount and expenses, were used to pay down debt. On April 12, 2001, the Company filed a Universal Shelf Registration Statement on Form S-3 with the Securities and Exchange Commission. The Universal Shelf allows the Company to offer, from time to time, an aggregate of up to $750 million in debt securities, preferred stock, depositary shares, common stock and related rights and warrants. On May 8, 2001, the Company utilized the shelf registration and completed a public offering of 8,500,000 primary shares of common stock. On May 16, 2001, the underwriters involved in the offering purchased an additional 424,200 shares pursuant to an over-allotment option granted by the Company in connection with the May 8, 2001 offering. The proceeds realized from these transactions after the underwriting discount and expenses were $279.3 million. These proceeds were used to pay down debt. The Company can still issue an additional $455.5 million in debt and equity securities under the Universal Shelf. On September 14, 2001, the Company's Board of Directors approved a stock repurchase plan, under which the Company may repurchase up to 6.0 million of its shares of common stock from time to time. Through December 31, 2001, the Company repurchased 357,200 shares of its common stock for $5.0 million pursuant to the plan at an average price of $14.13 per share. The repurchased shares are being held in the Company's treasury, which the Company accounts for using the average cost method. Future repurchases under the plan will be made at management's discretion and will depend on market conditions and other factors. As of December 31, 2000, the Company had acquired 1,726,900 shares under a prior repurchase program at an average price of $12.29 per share. All of the December 31, 2000 treasury shares were reissued in connection with the February 22, 2001 public offering discussed above. The Company also recognized proceeds of $8.9 million from sales of shares through the Company's employee stock option plan during the year ended December 31, 2001. 2001 Annual Report page 59. - --------------------------------------------------------------------------------

14. Stockholder Rights Plan On March 3, 2000, the Board of Directors adopted a stockholder rights plan under which preferred share purchase rights were distributed as a dividend to the Company's stockholders of record on March 20, 2000. The rights are exercisable only if a person or group acquires 20% or more of the Company's common stock (an "Acquiring Person") or announces a tender or exchange offer the consummation of which would result in ownership by a person or group of 20% or more of the Company's common stock. Each right entitles the holder to buy one one-hundredth of a share of a series of junior participating preferred stock at an exercise price of $42, or in certain circumstances allows the holder (except for the Acquiring Person) to purchase the Company's common stock or voting stock of the Acquiring Person at a discount. At its option, the Board of Directors may allow some or all holders (except for the Acquiring Person) to exchange their rights for Company common stock. The rights will expire on March 20, 2010, subject to earlier redemption or exchange by the Company as described in the plan. 15. Stock Incentive Plan and Other Incentive Plans Under the Company's 1997 Stock Incentive Plan (the "Company Incentive Plan"), 6,000,000 shares of the Company's common stock were reserved for awards to officers and other selected key management employees of the Company. The Company Incentive Plan provides the Board of Directors with the flexibility to grant stock options, stock appreciation rights (SARs), restricted stock awards, restricted stock units, performance stock or units, merit awards, phantom stock awards and rights to acquire stock through purchase under a stock purchase program ("awards"). Awards the Board of Directors elect to pay out in cash do not count against the 6,000,000 shares authorized in the Company Incentive Plan. As of December 31, 2001, performance units and stock options were the only types of awards granted. Stock options generally become exercisable in full or in part one year from the date of grant and are granted at a price equal to 100% of the fair market value of the stock on the date of grant. Performance stock or unit awards can be earned by the recipient if the Company meets certain pre-established performance measures. Until earned, the performance awards are nontransferable, and when earned, performance awards are payable in cash, stock, or restricted stock as determined by the Company's Board of Directors. As of December 31, 2001, 1.9 million performance units had been granted under the plan. Of the 1.9 million performance units awarded, 0.3 million had been earned and accrued under the plan. The remaining performance awards will be earned by participants based on Company performance for the years 2000 through 2003. The amount to be awarded under the remaining performance awards is based upon Company stock performance and is limited to a percentage of pre-tax income during the performance years. The Company accrues for anticipated awards to be paid out in cash over the life of the award. Information regarding stock options under the Company Incentive Plan is as follows for the years ended December 31, 2001, 2000 and 1999: 2001 2000 1999 --------------------------------------------------------------------- Weighted Weighted Weighted Common Average Common Average Common Average (in thousands, except per share data) Shares Price Shares Price Shares Price Options outstanding at January 1 1,589 $ 19.11 1,809 $ 19.33 1,128 $ 24.86 Granted 2,069 22.74 62 9.44 744 10.69 Exercised (442) 20.08 (9) 10.69 - - Canceled (63) 21.02 (273) 18.61 (63) 16.28 ------------------------------------------------------------------- Options outstanding at December 31 3,153 21.32 1,589 19.11 1,809 19.33 Options exercisable at =================================================================== December 31 859 $ 22.01 965 $ 23.57 837 $ 24.77 Options available for grant at December 31 2,299 4,305 4,094 Arch Coal, Inc. page 60 - --------------------------------------------------------------------------------

The Company applies APB 25, Accounting for Stock Issued to Employees, and related Interpretations in accounting for the Company Incentive Plan. Accordingly, no compensation expense has been recognized for the fixed stock option portion of the Company Incentive Plan. Had compensation expense for the fixed stock option portion of the Company Incentive Plan been determined based on the fair value at the grant dates for awards under this plan consistent with the method of FAS 123, Accounting for Stock-Based Compensation, the Company's net income (loss) and earnings (loss) per common share would have been changed to the pro forma amounts as indicated in the table below. The after-tax fair value of options granted in 2001, 2000 and 1999 was determined to be $13.5 million, $0.2 million and $2.9 million, respectively, which for purposes of these pro forma disclosures is recognized as compensation expense over the options' vesting period. The fair value of the options was determined using the Black-Scholes option pricing model and the weighted average assumptions noted below. Of the 2.1 million stock options granted in 2001, 1.7 million will vest in their entirety at December 31, 2003 while the remaining 0.4 million options vest ratably over three years. The stock options granted in 2000 and 1999 vest ratably over three and four years, respectively.

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. Sales to foreign countries are immaterial. As of December 31, 2001 and 2000, accounts receivable from electric utilities located in the United States totaled $129.7 million and $112.2 million, respectively, or 86% and 79% of total trade receivables, 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. 2001 Annual Report page 61. - --------------------------------------------------------------------------------

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. The Company and its operating subsidiaries sold approximately 109.5 million tons of coal in 2001. Approximately 77% of this tonnage and revenue was sold under long-term contracts (contracts having a term of greater than one year). Prices for coal sold under long-term contracts ranged from $3.59 to $55.33 per ton. Long-term contracts ranged in remaining life from one to 16 years. Some of these contracts include pricing which is above and, in some cases, materially above, current market prices. Sales (including spot sales)to major customers were as follows: Year ended December 31 (in thousands) 2001 2000 1999 AEP $ 191,443 $ 188,129 $ 157,278 Southern Company 217,909 161,553 163,826 17.

Related Party Transactions 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 administration fee arrangement is calculated annually and is approved by the Canyon Fuel Management Board. The production fee, which is defined in the LLC agreement, 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 $8.1 million, $7.4 million and $7.0 million for the years ended December 31, 2001, 2000 and 1999, respectively. Arch Coal, Inc. page 62. - --------------------------------------------------------------------------------

19. 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 $22.5 million in 2001, $22.7 million in 2000 and $42.2 million in 1999. The Company has also entered into various non-cancelable royalty lease agreements and federal lease bonus payments under which future minimum payments are due. On October 1, 1998, the Company was the successful bidder in a federal auction of certain mining rights in the 3,546 acre Thundercloud tract in the Powder River Basin of Wyoming. The Company's lease bonus bid amounted to $158 million for the tract, of which $31.6 million was paid on October 1, 1998 and $31.6 million was paid in both January 2000 and January 2001, respectively. The remaining lease bonus payments are reflected below as a component of "Royalties." The tract contains approximately 412 million tons of demonstrated coal reserves and is contiguous with the Company's Black Thunder mine. Geological surveys performed by outside consultants indicate that there are sufficient reserves relative to these properties to permit recovery of the Company's investment. Minimum payments due in future years under these agreements in effect at December 31, 2001 are as follows: Operating Capital (in thousands) Leases Royalties Leases 2002 $ 12,770 $ 59,725 $ 3,756 2003 10,384 62,564 3,756 2004 6,423 30,570 3,756 2005 6,300 27,434 1,701 2006 6,087 26,853 - Thereafter 9,516 154,273 - ----------------------------------- $ 51,480 $ 361,419 $12,969 =================================== Less amount representing interest $ 1,875 ------- Present value of net minimum lease payments under capital leases 11,094 Current portion 2,884 ------- Long-term capitalized lease obligations $ 8,210 ======= Property, plant and equipment at year-end include the following amounts for capitalized leases: December 31 (in thousands) 2001 Plant and Equipment $ 15,228 Accumulated amortization 4,521 -------- $ 10,707 ======== 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. The Company holds a 17.5% general partnership interest in Dominion Terminal Associates ("DTA"), which operates a ground storage-to-vessel coal transloading facility in Newport News, Virginia. DTA leases the facility from Peninsula Ports Authority of Virginia ("PPAV") for amounts sufficient to meet debt-service requirements. Financing is provided through $132.8 million of tax-exempt bonds issued by PPAV (of which the Company is responsible for 17.5%, or $23.2 million) which mature July 1, 2016. Under the terms of a throughput and handling agreement with DTA, each partner is charged its share of cash operating and debt-service costs in exchange for the right to use its share of the facility's loading capacity 2001 Annual Report page 63. - --------------------------------------------------------------------------------

and is required to make periodic cash advances to DTA to fund such costs. On a cumulative basis, costs exceeded cash advances by $11.9 million at December 31, 2001 (included in other noncurrent liabilities). Future payments for fixed operating costs and debt service are estimated to approximate $3.3 million annually through 2015 and $26.0 million in 2016. In connection with the Company's acquisition of the coal operations of Atlantic Richfield Company ("ARCO"), which is now BP Amoco, and the simultaneous combination of the acquired ARCO operations and the Company's Wyoming operations into a new joint venture named Arch Western, the Company agreed to indemnify another member of Arch Western against certain tax liabilities in the event that such liabilities arise as a result of certain actions taken prior to June 1, 2013, including the sale or other disposition of certain properties of Arch Western, the repurchase of certain equity interests in Arch Western by Arch Western or the reduction under certain circumstances of indebtedness incurred by Arch Western in connection with the acquisition. Depending on the time at which any such indemnification obligation was to arise, it could have a material adverse effect on the business, results of operations and financial condition of the Company. 20.

On July 12, 2000, after controlling the combustion-related gases, the Company resumed production at the West Elk mine and started to ramp up to normal levels of production. The Company recognized partial pre-tax insurance settlements of $12.0 million during each of the second and third quarters of 2000, $7.0 million during the fourth quarter of 2000 and a final pre-tax insurance settlement related to the event of $9.4 million during the second quarter of 2001. (2) During the first quarter of 2001, the fourth quarter of 2001 and the second quarter of 2000, the Company recognized an increase of pre-tax income of $3.5 million, $2.1 million and $7.8 million from a reduction in the amount of expected reclamation work at the Company's idle Illinois property because of permit revisions. (3) During the second quarter of 2000, the IRS issued a notice outlining the procedures for obtaining tax refunds on certain excise taxes paid by the industry on export sales tonnage. The notice was the result of a 1998 federal court decision that found such taxes to be unconstitutional. The Company recorded $12.7 million of pre-tax income related to these excise tax recoveries during the second quarter of 2000. During the second quarter of 2001, the Company recorded an additional $1.5 million of pre-tax income resulting from additional favorable developments associated with these tax refunds. (4) During the fourth quarter of 2001, the Company recognized a $7.4 million pre-tax gain from a state tax credit covering prior periods. (5) During the fourth quarter of 2001, the Company increased its litigation reserves reducing pre-tax income by $5.6 million resulting from several litigation settlements. (6) During the fourth quarter of 2000, as a result of adjustments to employee postretirement medical benefits, the Company was able to recognize $9.8 million of pre-tax curtailment gains resulting from previously unrecognized postretirement benefit changes which occurred in prior years. (7) During the fourth quarter of 2000, the Company settled certain workers' compensation liabilities with the state of West Virginia partially offset by adjusting other workers' compensation liabilities resulting in a net pre-tax gain of $8.3 million. (8) The sum of the quarterly earnings (loss) per common share amounts may not equal earnings (loss) per common share for the full year because per share amounts are computed independently for each quarter and for the year based on the weighted average number of common shares outstanding during each period. 2001 Annual Report page 65. - --------------------------------------------------------------------------------

(1) At the West Elk underground mine in Gunnison County, Colorado, following the detection of combustion-related gases in a portion of the mine, the Company idled its operation on January 28, 2000. On July 12, 2000, after controlling the combustion-related gases, the Company resumed production at the West Elk mine and started to ramp up to normal levels of production. The Company recognized partial pre-tax insurance settlements of $31.0 million during 2000 and a final pre-tax insurance settlement related to the event of $9.4 million during 2001. (2) The IRS issued a notice outlining the procedures for obtaining tax refunds on certain excise taxes paid by the industry on export sales tonnage. The notice was the result of a 1998 federal court decision that found such taxes to be unconstitutional. The Company recorded $12.7 million of pre-tax income related to these excise tax recoveries during 2000. During 2001 the Company recorded an additional $4.6 million of pre-tax income resulting from additional favorable developments associated with these tax refunds. (3) The Company recognized a $7.4 million pre-tax gain during 2001 from a state tax credit covering prior periods. (4) As a result of adjustments to employee postretirement medical benefits, the Company was able to recognize $9.8 million of pre-tax curtailment gains resulting from previously unrecognized postretirement benefit changes which occurred in prior years. (5) The Company settled certain workers' compensation liabilities with the state of West Virginia partially offset by adjusting other workers' compensation liabilities resulting in a net pre-tax gain of $8.3 million. (6) The Company changed its depreciation method on preparation plants and loadouts during the first quarter of 1999 and recorded a cumulative effect of applying the new method for years prior to 1999 which resulted in a decrease to net loss in 1999 of $3.8 million net-of-tax. (7) The loss from operations for 1999 reflects one-time pre-tax charges of $387.7 million related principally to the write-down of assets at its Dal-Tex, Hobet 21 and Coal-Mac operations and the write-down of certain other coal reserves in Central Appalachia. Included in this charge was a $23.1 million pre-tax charge related to the restructuring of the Company's administrative work force and the closure of mines in Illinois, Kentucky and West Virginia. (8) Information for 1998 reflects the acquisition of Atlantic Richfield Company's domestic coal operations on June 1, 1998. As a result of the refinancing of Company debt resulting from the acquisition, the Company incurred an extraordinary charge of $1.5 million (net-of-tax benefit) related to the early extinguishment of debt which existed prior to the acquisition. (9) Income from operations for 1998 reflects pre-tax gains of $41.8 million from the disposition of assets including $18.5 million and $7.5 million on the sale of certain assets and property in eastern Kentucky and the sale of the Company's idle Big Sandy Terminal, respectively. (10) Information for 1997 reflects the merger with Ashland Coal on July 1, 1997. (11) Income from operations for 1997 reflects a $39.1 million charge in connection with the Ashland Coal merger comprised of termination benefits, relocation costs and costs associated with duplicate facilities. (12) On April 4, 1997, the Company changed its capital stock whereby the number of authorized shares was increased to 100,000,000 common shares, the par value was changed to $.01 per share, and a common stock split of 338.0857-for-one was effected. All share and per share information reflect the stock split. (13) Adjusted EBITDA is defined as income (loss) from operations before the effect of changes in accounting principles and extraordinary items (Notes 6 and 8 above); merger-related costs, unusual items, asset impairment and restructuring charges (Notes 7 and 11 above); net interest expense; income taxes; depreciation, depletion and amortization of Arch Coal, its subsidiaries and its ownership percentage in its equity investments. Adjusted EBITDA is presented because it is a widely accepted financial indicator of a company's ability to incur and service debt. Adjusted EBITDA should not be considered in isolation nor as an alternative to net income, operating income, cash flows from operations or as a measure of a company's profitability, liquidity or performance under U.S. generally accepted accounting principles. This measure of adjusted EBITDA may not be comparable to similar measures reported by other companies, or adjusted EBITDA may be computed differently by the Company in different contexts (i.e., public reporting versus computations under financing arrangements). 2001 Annual Report page 67. - --------------------------------------------------------------------------------

Canyon Fuel Company, LLC Notes to Financial Statements December 31, 2001 1. The Company Canyon Fuel Company, LLC (the Company) is a joint venture between Arch Western Resources, LLC (Arch Western) (65 percent ownership) and ITOCHU Coal International Inc. (ITOCHU) (35 percent ownership). The owners of the Company are referred to herein as the "Members." The Company owns an approximate 9 percent interest in Los Angeles Export Terminal, Inc. (LAXT). The Company operates one reportable segment: the production of steam coal from deep mines in Utah for sale primarily to utility companies in the United States. Net profits and losses are allocated to the Members based on their respective ownership percentage. Distributions of the Company's earnings are also allocated to the Members based on their respective ownership percentage. 2. Accounting Policies 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 which approximates fair value. Cash equivalents consist of highly liquid investments with an original maturity of three months or less when purchased. 6

Canyon Fuel Company, LLC Notes to Financial Statements (continued) 2. Accounting Policies (continued) Inventories Inventories consist of the following: December 31 2001 2000 ----------------------------------- (In Thousands) Coal $12,537 $10,963 Supplies, net of allowance 8,993 9,428 ----------------------------------- $21,530 $20,391 =================================== Coal inventory is valued using the first-in, first-out (FIFO) cost method and is stated at the lower of cost or market. Coal inventory costs include labor, equipment costs and operating overhead. Supplies are valued using the average cost method and are stated at the lower of cost or market. The Company has recorded a valuation allowance for slow-moving and obsolete supplies inventories of $35 thousand and $121 thousand at December 31, 2001 and 2000, respectively. Coal Acquisition Costs and Prepaid Royalties Coal lease rights obtained through acquisition are capitalized and amortized primarily by the units-of-production method over the estimated recoverable reserves. Amortization occurs as the Company mines on the property. Rights to leased coal lands are often acquired through royalty payments. Where royalty payments represent prepayments recoupable against future production, they are capitalized. As mining occurs on these leases, the prepayment is charged to cost of coal sales. Coal Supply Agreements Acquisition costs related to coal supply agreements 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 $91.9 million and $74.8 million at December 31, 2001 and 2000, respectively. 7

Mine development costs are capitalized and amortized on the units-of-production method over the estimated recoverable reserves that are associated with the property being benefited. Depletion of mineral properties is computed on the units-of-production method over the estimated recoverable coal reserves of the property being mined. At December 31, 2001, all mineral reserves of the Company that are capitalized are being amortized on the units-of-production method through Company operations. Depreciation and amortization of other property, plant and equipment are computed by the straight-line method over the expected lives of the assets, which range from 3 to 16 years. Fully depreciated assets are retained in property and accumulated depreciation accounts until they are removed from service. Upon disposal of depreciated assets, residual cost less salvage value is included in the determination of current income. 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. As described in Note 3, the Company wrote off the value of its investment in LAXT during 2001. 8

Canyon Fuel Company, LLC Notes to Financial Statements (continued) 2. Accounting Policies (continued) Reclamation and Mine Closing Costs The Company charges current reclamation costs to expense as incurred. Final reclamation costs, including dismantling and restoration, are estimated based upon current federal and state regulatory requirements and are accrued during operations using the units-of-production method on the basis of estimated costs as of the balance sheet date. The effect of changes in estimated costs and production is recognized on a prospective basis. The Company is not aware of any events of noncompliance with environmental laws and regulations. The exact nature of environmental issues and costs, if any, which the Company may encounter in the future cannot be predicted, primarily because of the changing character of environmental requirements that may be enacted by governmental agencies. Accrued Workers' Compensation Costs 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 state 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 traumatic injuries which are accrued as injuries are incurred. Revenue Recognition Coal sales revenues include sales to customers of coal produced at Company operations and 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 performed or otherwise earned. 9

Canyon Fuel Company, LLC Notes to Financial Statements (continued) 2. Accounting Policies (continued) Income Taxes The financial statements do not include a provision for income taxes, as the Company is treated as a partnership for income tax purposes and does not incur federal or state income taxes. Instead, its earnings and losses are included in the Members' separate income tax returns. Comprehensive Income The Company reports comprehensive income in its Statement of Members' Equity. Comprehensive income represents changes in Members' equity from non-owner sources. For the year ended December 31, 2001, minimum pension liability adjustments were the only item of other comprehensive income for the year ended December 31, 2001: Year Ended December 31, 2001 ------------------- (In Thousands) Net income (as reported) $26,026 Minimum pension liability adjustment (3,143) ------------------- Total comprehensive income $22,883 =================== Derivative Instruments FAS 133, Accounting for Derivative Instruments and Hedging Activity, was effective 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 derivative is at offsetting price movements in the underlying exposure. As required, the Company adopted FAS 133 on January 1, 2001. The Company did not have any financial instruments which qualified as derivatives under FAS 133, and therefore, there was no impact to the Company as a result of the adoption of FAS 133. 10

Canyon Fuel Company, LLC Notes to Financial Statements (continued) 3. Non-Recurring Income and Expenses The Company owns an approximate 9 percent interest in LAXT which the Company has included in property, plant and equipment. LAXT began operations in 1997 and has experienced operating losses and negative cash flows since its inception, principally due to weak demand for U.S. coal exports to the Pacific Rim countries. During 2001, there was continuing weakness in the export coal market, LAXT's financial condition was not going to allow it to make its Minimum Annual Guarantee Rental Payment owed to the Port of Los Angeles and several significant owners of LAXT indicated an unwillingness to provide additional funding to LAXT. The Company believes these events represent indicators of impairment under the provisions of FAS 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of. Based on this, the Company determined that assets with a carrying value of $10.1 million did not have any future value to the Company and therefore were written off. In addition, the Company had a $2.3 million note receivable from LAXT which it no longer expects to realize and wrote off during 2001. During 2001, the Company received notification that contested property tax valuations from 1998 and 1999 were settled in the Company's favor. The Company recognized $4.5 million of income in 2001, which is the amount refunded by the state of Utah to the Company. In addition, the Internal Revenue Service issued a notice during 2000 outlining the procedures for obtaining tax refunds on certain excise taxes paid by the industry on export sales tonnage. The notice is a result of a 1998 Federal District Court decision that found such taxes to be unconstitutional. As a result of processing these claims during 2001, the Company recorded $2.2 million of income related to these excise tax recoveries. 4. Accrued Expenses Accrued expenses included in current liabilities consist of the following: December 31 2001 2000 --------------------------------- (In Thousands) Payroll and related benefits $2,188 $3,590 Pension 2,118 624 Postretirement benefits other than pension 359 81 Taxes other than income taxes 1,104 968 Workers' compensation 411 549 Other accrued expenses 1,880 1,716 --------------------------------- $8,060 $7,528 ================================= 11

Canyon Fuel Company, LLC Notes to Financial Statements (continued) 5. Employee Benefit Plans Defined Benefit Pension and Other Postretirement Benefit Plans Essentially all of the Company's employees are covered by a defined benefit pension plan sponsored by the Company. The benefits are based on years of service and the employee's compensation, primarily during the last five years of service. The funding policy for the pension plan is to make annual contributions as required by applicable regulations. The Company also provides certain postretirement medical and life insurance benefits to substantially all employees who retire with the Company. The Company has the right to modify the plans at any time. The Company's current policy is to fund the cost of postretirement medical and life insurance benefits as they are paid. 12

Canyon Fuel Company, LLC Notes to Financial Statements (continued) 5. Employee Benefit Plans (continued) Demographic and assumption changes under the defined benefit pension plan resulted in a $1.3 million loss and a $2.1 million loss in 2001 and 2000, respectively. The decrease in the funded status of pension benefits in the year 2001 resulted from decreased earnings on plan assets during the year. FAS 87, Employers' Accounting for Pensions, contains a minimum liability provision that requires, in some situations, that an employer recognize an "additional minimum liability" in the balance sheet without a corresponding charge to earnings. To the extent an additional minimum liability is required, a corresponding reduction in equity may also be recognized. Demographic and assumption changes in other postretirement benefits resulted in the $0.6 million and $1.4 million gain in 2001 and 2000, respectively. The $2.9 million reduction in the postretirement benefit obligation in 2000 associated with plan amendments resulted from a July 2000 amendment changing some of the cost-sharing provisions of the plan for salaried and nonunion hourly participants and an October 2000 plan amendment changing eligibility requirements to ten years of service after reaching the age of 45 for salaried and nonunion hourly participants. The latter plan change triggered a curtailment that resulted in the recognition of $0.4 million in previously unrecognized prior service gains. Other Postretirement Pension Benefits Benefits ------------------------------------------------------ 2001 2000 2001 2000 ------------------------------------------------------ Weighted average assumptions as of December 31: Discount rate 7.50% 7.75% 7.50% 7.75% Rate of compensation increase 4.50% 4.75% N/A N/A Expected return on plan assets 9.00% 9.00% N/A N/A Health care cost trend on covered charges N/A N/A 5.00% 5.00% 14

Canyon Fuel Company, LLC Notes to Financial Statements (continued) 5. Employee Benefit Plans (continued) The following table details the components of pension and other postretirement benefit costs: Other Postretirement Pension Benefits Benefits --------------------------------------------------------------------- 2001 2000 1999 2001 2000 1999 --------------------------------------------------------------------- (In Thousands) Service cost $1,951 $1,760 $1,760 $316 $271 $ 415 Interest cost 810 591 338 393 542 619 Expected return on plan assets (660) (648) (166) - - - Other amortization and deferral 642 391 153 (548) (208) 296 Curtailments - - - - (443) - --------------------------------------------------------------------- $2,743 $2,094 $2,085 $161 $162 $1,330 ===================================================================== The health care cost trend rate assumption has a significant effect on the amounts reported. However, as the employer contribution cap is expected to be reached in 2002, the impact of health care cost trend rate changes is not material. Other Plans The Company sponsors a 401(k) savings plan which was established to assist eligible employees in providing for their future retirement needs. The savings plan matches a certain percentage of employee contributions. The Company's contribution to the savings plan was $1.4 million in 2001 and $1.3 million in 2000. 6. 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. 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 15

Canyon Fuel Company, LLC Notes to Financial Statements (continued) 6. Concentration of Credit Risk and Major Customers (continued) indices. Quantities sold under some of these contracts may vary from year to year within certain limits at the option of the customer. IPA accounted for approximately 36 percent, 44 percent and 34 percent of coal sales in 2001, 2000 and 1999, respectively. This same customer accounted for 31 percent and 53 percent of accounts receivable at December 31, 2001 and 2000, respectively. Sierra Pacific accounted for approximately 13 percent, 12 percent and 11 percent of coal sales in 2001, 2000 and 1999, respectively. Approximately 6 percent, 8 percent and 6 percent of coal sales in 2001, 2000 and 1999, respectively, were export sales to Japanese customers. 7. Related Party Transactions As described in Note 1, 65 percent of the Company is owned by Arch Western. Arch Western acts as the Company's managing Member. The Company pays administration and production fees to Arch Western for managing the Company's operations. In addition, the Company pays certain additional management fees to ITOCHU, its 35 percent owner. These fees to Members were $8.9 million, $8.0 million and $7.8 million in 2001, 2000 and 1999, respectively. The Company has a payable balance to its Members of $2.8 million and $3.8 million at December 31, 2001 and 2000, respectively. 8. Commitments and Contingencies The Company has entered into various noncancelable royalty lease agreements and federal lease bonus payments under which future minimum payments are due. In May 2001, the Company was the successful bidder in a state auction of certain mining rights in the 2,560-acre Dugout tract in Carbon County, Utah. The Company's lease bid amounted to $1.0 million for the tract, of which $100 thousand was paid in 2001. The Company will make payments of $100 thousand in each of the years of 2002 through 2004 and $120 thousand in each of the years 2005 through 2009. The tract contains approximately 6 million tons of demonstrated coal reserves and is contiguous to the Company's Dugout mine. In May 1999, the Company was the successful bidder in a federal auction of certain mining rights in the 7,172-acre Pines tract in Sevier and Emory Counties in Utah. The Company's lease bonus bid amounted to $16.9 million for the tract, of which $3.4 million was paid on May 24, 1999 and an additional $3.4 million was paid in each of the years 2001 and 2000, respectively. The tract contains approximately 60 million tons of demonstrated coal reserves and is contiguous with the Company's Sufco mine. Geological surveys indicate that there are sufficient reserves relative to these properties to permit recovery of the Company's investment. Minimum payments due in future years under lease agreements (including the Dugout and Pines tract leases) are $3.5 16

Canyon Fuel Company, LLC Notes to Financial Statements (continued) 8. Commitments and Contingencies (continued) million in 2002, $3.5 million in 2003, $100 thousand in 2004 and $120 thousand in each of the years 2005 through 2009. The Company was in litigation with Skyline Partners, lessors of the coal reserves which comprise the Company's Skyline mine. The coal leases required the Company to make annual advance minimum royalty payments which are fully recoupable against a production royalty that is to be paid by the Company on each ton of coal mined and sold from the leaseholds. In 1997, the Company filed suit against Skyline Partners in Utah State Court alleging that the Company was not required to make the final minimum advance royalty payment. On February 24, 2000, the Company and Skyline Partners reached an agreement to settle the litigation. The settlement includes a $7.2 million recoupable payment by the Company to Skyline Partners which was recorded as a prepaid royalty in 2000 and a grant of an overriding royalty interest to Skyline Partners covering land adjacent to the Skyline mine reserves. The Company is also the subject of or party to a number of other pending or threatened legal actions. On the basis of management's best assessment of the likely outcome of these actions, expenses or judgments arising from any of these suits are not expected to have a material adverse effect on the Company's operations, financial position or cash flows. 9. Cash Flow The changes in operating assets and liabilities as shown in the statements of cash flows are comprised of the following: 2001 2000 1999 ------------------------------------------------------ (In Thousands) Decrease (increase) in operating assets: Receivables $(1,734) $(10,264) $ 9,500 Inventories (1,139) 5,039 (1,588) Increase (decrease) in operating liabilities: Accounts payable and accrued expenses (3,605) (3,930) 5,606 Accrued postretirement benefits other than pension (497) - 1,317 Accrued reclamation and mine closure 598 369 487 Accrued workers' compensation (478) 626 (833) ------------------------------------------------------ $(6,855) $ (8,160) $14,489 ====================================================== 17

Canyon Fuel Company, LLC Notes to Financial Statements (continued) 10. Accounting Development In June 2001, the Financial Accounting Standards Board issued FAS 143, Accounting for Asset Retirement Obligations, which is effective for fiscal years beginning after June 15, 2002. FAS 143 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 should be capitalized as part of the related long-lived asset and allocated to expense over the useful life of the asset. The Company will adopt FAS 143 on January 1, 2003. Due to the extensive amount of information that must be reviewed and estimates that must be made to assess the effects of FAS 143, the expected impact of adoption of FAS 143 on the Company's financial position or results of operations has not yet been determined. 18
