ARCH COAL, INC. EMPLOYEE THRIFT PLAN - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2001 AND 2000 1. DESCRIPTION OF THE PLAN The Arch Coal, Inc. Employee Thrift Plan was established by Arch Coal, Inc. for the benefit of the eligible employees of the Company, its subsidiaries and controlled affiliates. The following description of the Plan provides only general information. Participants should refer to the Summary Plan Description for a more complete description of the Plan's provisions. Certain provisions of the Plan as described below do not apply to or have been modified for certain subsidiaries and affiliates of the Company. GENERAL The Plan, which has been adopted by Arch Coal, Inc. is a defined contribution profit sharing plan which includes a 401(k) provision. The Plan covers all full-time salaried employees, all full-time nonunion hourly employees, and certain union employees where specified by applicable collective bargaining agreements of the Company, its subsidiaries, and any controlled affiliates that elect to participate in the Plan. It is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). CONTRIBUTIONS Participants may elect to defer between 1 percent and 17 percent of compensation, depending upon the location of the employee. The percentage of employer match or nondiscretionary contribution also depends upon the location. PARTICIPANT ACCOUNTS Each participant's account is credited with the participant's contributions, the employer's matching contribution, if applicable, or employer non-discretionary contribution, if applicable, and an allocation of Plan earnings. The allocation of earnings is determined by the earnings of the participant's investment selection based on each participant's account balance, as defined in the Plan agreement. The benefit to which a participant is entitled is the benefit that can be provided from the participant's account. VESTING Participants are fully vested in their contributions plus actual earnings. All eligible employees of the Company at December 31, 1997 became fully vested in the Plan. Eligible employees hired subsequent to December 31, 1997 vest in Company contributions and earnings upon the completion of three full and consecutive years of service. - -------------------------------------------------------------------------------- Page 5

ARCH COAL, INC. EMPLOYEE THRIFT PLAN - -------------------------------------------------------------------------------- Notes To Financial Statements (Continued) All participants become fully vested upon death while employed, total disability, or normal retirement age, regardless of the number of months of participation. NOTES RECEIVABLE - PARTICIPANTS Active participants, with some exceptions, may borrow from their fund accounts a minimum of $500 or up to a maximum equal to the lesser of $50,000 or 50 percent of their vested account balances. Loan terms range from one to five years or longer for the purchase of a primary residence. The loans are secured by the balance in the participant's account and bear interest at the prime rate listed in the Wall Street Journal on the day the loan is processed. Principal and interest is paid ratably through payroll deductions. PAYMENT OF BENEFITS Upon death, termination of service, or attainment of age 70-1/2, a participant may elect to receive either a lump-sum amount equal to the value of the participant's vested interest in his or her account, a single annuity, a joint and survivorship annuity with various survivor options or a series of installment payments. FORFEITED ACCOUNTS Forfeited amounts of employer contributions are used to offset future company matching contributions of the Plan. At December 31, 2001, forfeited amounts available to reduce future company contributions were $185,074. INVESTMENT OPTIONS Participants may direct the investment of their entire account balance among the following investment options: AMERICAN CENTURY INCOME & GROWTH FUND This fund seeks capital growth. The fund typically invests at least 90% of assets in equities selected for their appreciation potential.

ARCH COAL, INC. EMPLOYEE THRIFT PLAN - -------------------------------------------------------------------------------- Notes To Financial Statements (Continued) 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ESTIMATES AND ASSUMPTIONS The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, 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. BASIS OF ACCOUNTING The financial statements of the Plan are prepared under the accrual method of accounting. INVESTMENT VALUATION AND INCOME RECOGNITION Investments in mutual funds are valued at reported net asset value at December 31 as determined by the fund manager. Investment income is recorded as earned on the accrual basis. PAYMENT OF BENEFITS Benefits are recorded when paid. - -------------------------------------------------------------------------------- Page 9

TAX STATUS The Plan obtained its latest determination letter on August 9, 1996 in which the Internal Revenue Service stated that the Plan, as then designed, was in compliance with the applicable requirements of the Internal Revenue Code. The Plan has been amended during 2001 to incorporate language required by the passing of certain laws, commonly referred to as "GUST." The Plan Administrator has filed for a determination letter for the Plan as amended. The Plan Administrator and the Plan's tax counsel believe the Plan is correctly designed and operated with the applicable requirements of the Internal Revenue Code.
