                          INDEPENDENT AUDITORS' REPORT


To the Trustees
Arch Coal, Inc. Employee Thrift Plan
St. Louis, Missouri


We have audited the accompanying statement of net assets available for plan
benefits of the Arch Coal, Inc. Employee Thrift Plan as of December 31, 2001 and
the related statement of changes in net assets available for plan benefits for
the year then ended. These financial statements are the responsibility of the
Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audit.

We conducted our audit in accordance with auditing standards generally accepted
in the United States of America. 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 audit provides a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for plan benefits at December
31, 2001, and the changes in net assets available for benefits for the year then
ended in conformity with accounting principles generally accepted in the United

                          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. The majority of these securities are common stocks
                issued by companies that meet management's standards for
                earnings and revenue growth. The fund may only purchase
                securities of companies that have operated more than 3 years.

                ARCH COAL, INC. COMMON STOCK

                Funds are invested in Arch Coal, Inc. common stock.

Notes To Financial Statements (Continued)

                BARCLAY'S LIFEPATH 2010

                This fund seeks total return for investors retiring near the
                year 2010. The fund uses an asset allocation approach. The
                allocation changes become more conservative as the fund nears
                its maturation. The fund allocates among securities contained in
                various domestic and foreign indexes.

                BARCLAY'S LIFEPATH 2020

                This fund seeks total return for investors retiring near the
                year 2020. Asset allocation is the same as the Barclay's
                Lifepath 2010 as noted above.

                BARCLAY'S LIFEPATH 2030

                This fund seeks total return for investors retiring near the
                year 2030. Asset allocation is the same as the Barclay's
                Lifepath 2010 as noted above.

                BARCLAY'S LIFEPATH 2040

                This fund seeks total return for investors retiring near the
                year 2040. The fund uses an asset allocation approach with a
                neutral mix consisting of 100% equities. Otherwise, asset
                allocation is the same as the Barclay's Lifepath 2010 as noted
                above.

                CSFB DIRECT PERSONAL CHOICE RETIREMENT ACCOUNT

                This is an option wherein a plan participant can invest directly
                in equity and debt securities through a CSFB Direct brokerage

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.

         Interest income on the Primco Stable Value Fund is calculated and
         credited daily based on the aggregate contract yield of the underlying
         investments. The investment contracts included in this fund had an
         average yield of 5.52% for the year ended December 31, 2001. The
         average crediting interest rate was 5.87% at December 31, 2001. The
         fair value of the investment contract was $50,853,111 at December 31,
         2001.


4.       NOTES RECEIVABLE - PARTICIPANTS

         Notes receivable are secured by participants' vested balances. The
         notes are due in bi-weekly payments including principal and interest at
         varying rates reflective of the prime rate as of the time of issue. The
         final installments are due at various dates.


5.       PLAN TERMINATION

         Although it has not expressed intent to do so, the Company has the
         right under the Plan to discontinue its contributions at any time and
         to terminate the Plan, subject to the provisions of ERISA. In the event
         of Plan termination, participants will become 100% vested in their
         accounts.


6.       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.
         Therefore, the Plan Administrator believes the Plan was qualified and
         the related trust tax exempt.

            INDEPENDENT AUDITORS' REPORT ON SUPPLEMENTARY INFORMATION


Our audit was made for the purpose of forming an opinion on the basic financial
statements taken as a whole. The schedule of assets held for investment purposes
is presented for purposes of additional analysis and is not a required part of
the basic financial statements, but is supplementary data required by the
Department of Labor's Rules and Regulations for Reporting and Disclosure under
the Employee Income Security Act of 1974. Such information has been subjected to
the auditing procedures applied in the audit of the basic financial statements
and, in our opinion, is fairly stated in all material respects in relation to
the basic financial statements taken as a whole.
