We have audited the accompanying statements of net assets available for benefits of Peabody Holding Company, Inc. Employee Retirement Account as of December 31, 2002 and 2001, and the related statements of changes in net assets available for benefits for the years 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 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 present fairly, in all material respects, the net assets available for benefits of the Plan at December 31, 2002 and 2001, and the changes in its net assets available for benefits for the years then ended, in conformity with accounting principles generally accepted in the United States. Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December 31, 2002 is presented for purposes of additional analysis and is not a required part of the financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in our audits of the financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole. /s/ ERNST & YOUNG LLP --------------------- Ernst & Young LLP St. Louis, Missouri May 16, 2003 1 Peabody Holding Company, Inc.

Employee Retirement Account Notes to Financial Statements Years Ended December 31, 2002 and 2001 1. DESCRIPTION OF THE PLAN The following description of the Peabody Holding Company, Inc. (the Company) Employee Retirement Account (the Plan) provides only general information. Participants should refer to the plan documents for a more complete description of the Plan's provisions. The Plan was amended and restated effective April 1, 1999. GENERAL The Plan is a defined contribution plan, and participation in the Plan is voluntary. All salaried employees of the Company and certain of its participating subsidiary companies as well as the salaried employees of participating affiliated companies (collectively referred to as the "Employer") are eligible for participation on the date of their employment or at any time afterward. It is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). The Plan allows participants to invest among several mutual funds and common/collective trusts. Effective October 2001, the Plan allows participants to invest in the Peabody Energy Stock Fund, as a result of Peabody Energy Corporation's initial public offering of common stock in May 2001. All investments in the Plan are participant-directed. CONTRIBUTIONS Each year, participants may contribute from 2% to 50% of pretax or after-tax annual compensation, as defined in the Plan. Prior to April 1, 2002, participants could contribute up to 16% of pretax or after-tax annual compensation, as defined in the Plan. Participants who were employees of Powder River Coal Company could contribute up to 19% of pretax or after-tax annual compensation. Participants may also contribute amounts representing distributions from other qualified defined benefit or defined contribution plans. Participants direct the investment of their contributions into various investment options offered by the Plan. Effective April 1, 2002, in the calendar year that a participant is age 50 or older and each year thereafter, certain participants meeting additional specific criteria will be permitted to make catch-up contributions to the Plan. Participants will be able to contribute amounts over and above the maximum otherwise permitted by the Plan, subject to certain limitations. 4 Peabody Holding Company, Inc. Employee Retirement Account Notes to Financial Statements (continued) 1. DESCRIPTION OF THE PLAN (CONTINUED) The Company makes matching contributions of an amount equal to 100% on the first 3% of base pay and 75% on the next 4% of base pay that a participant contributes to the Plan. For participants who are employed by Powder River Coal Company, the Company makes matching contributions of an amount equal to 50% of the first 6% of compensation that a participant contributes to the Plan. Prior to August 1, 2002, for participants who were employed by Patriot Coal Company, the Company made matching contributions of an amount equal to 50% of the first 4% of compensation that a participant contributed to the Plan. Employees direct the investment of Company contributions. All contributions are subject to certain limitations. Effective April 1, 1999, the Company's Board of Directors set desired minimum and maximum performance targets that will require the Company to pay into the account of each active employee of the Company and its participating subsidiaries and affiliates an amount between 0% and 4% of the employee's base salary as of the end of the fiscal year. Effective January 1, 2002, if the Company does not meet the minimum performance targets set by the Board for the Company's fiscal year, the Board may authorize the Company to contribute to the Plan a discretionary amount. In July 2001, the Company changed its fiscal year-end from March 31 to December 31. This change was first effective with respect to the nine months ended December 31, 2001. The Plan's year-end of December 31 remained unchanged. During the 2002 plan year, a receivable of approximately $0.8 million was recorded, which represented a discretionary contribution of 1% of eligible employees' salaries for the year ended December 31, 2002. During the 2001 plan year, a performance contribution of approximately $2.8 million was made, which represented 4% of eligible employees' salaries for the fiscal year ended March 31, 2001, and a receivable of approximately $2.2 million was recorded, which represented 3% of eligible employees' salaries for the nine months ended December 31, 2001. FORFEITED ACCOUNTS Employer contributions are reduced by forfeitures of nonvested amounts. The forfeiture credits amounted to $58,486 and $26,689 for the years ended December 31, 2002 and 2001, respectively. As of December 31, 2002, $55,038 of the current year forfeiture credits were unapplied. 5 Peabody Holding Company, Inc. Employee Retirement Account Notes to Financial Statements (continued) 1. DESCRIPTION OF THE PLAN (CONTINUED) PARTICIPANT LOANS Participants may borrow from their fund accounts a minimum of $1,000 up to a maximum equal to the lesser of $50,000 or 50% of their vested account balance. The loans are secured by the balance in the participant's account and bear interest at rates commensurate with the prime interest rate as published in The Wall Street Journal on the first business day of the month in which the loan was made. Principal and interest is paid ratably through payroll deductions. Effective October 1, 2002, loan fees are paid by participants. PARTICIPANT ACCOUNTS Each participant's account is credited with the participant's contribution and allocations of (a) the Company's contribution and (b) plan earnings. Allocations are based on participant eligible compensation or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. PAYMENT OF BENEFITS On termination of service due to death, disability, or retirement, 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, annual installments, or a combination of the two. For termination of service for other reasons, a participant may receive the value of the vested interest in his or her account as a lump-sum distribution. Participants may also elect to receive a lump-sum distribution from their after-tax account. Participants who have attained the age of 59 1/2 have the right to receive part or all of their vested account balance upon request. Withdrawals in cases of hardship, as defined in the Plan, are also permitted. 6 Peabody Holding Company, Inc. Employee Retirement Account Notes to Financial Statements (continued) 1. DESCRIPTION OF THE PLAN (CONTINUED) VESTING Participants are vested immediately in their contributions plus actual earnings thereon. Vesting in the Company matching contribution portion of their accounts is based on years of continuous service or when the participant attains the age of 62, whichever occurs first. Employer matching contributions and earnings thereon become vested based upon years of service (25% per year after two years of service with 100% vesting after five years) with the Company. Employer performance contributions, if any, are 100% vested immediately. PLAN TERMINATION The Plan is voluntary on the part of the Employer. The Employer may terminate the Plan in whole or in part subject to the provisions of ERISA. Upon termination or complete discontinuance of all contributions to the Plan, participants' accounts become fully vested. Currently, the Employer has no intention to terminate the Plan. ADMINISTRATIVE EXPENSES All significant administrative expenses of the Plan, including recordkeeping and trustee fees, are paid by the Employer. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION The financial statements of the Plan are prepared under the accrual method of accounting. USE OF ESTIMATES The preparation of the 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, the disclosure of contingent liabilities at the date of the financial statements, and reported amounts of additions and deductions during the reporting period. Actual results could differ from these estimates. 7 Peabody Holding Company, Inc. Employee Retirement Account Notes to Financial Statements (continued) 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) VALUATION OF INVESTMENTS AND INCOME RECOGNITION The Plan's investments are stated at fair value. Shares of mutual funds are valued at quoted market prices, which represent the net asset value of shares held by the Plan at year-end. Units in common/collective trust are valued at net asset value at year-end. The stock fund is valued at year-end unit closing price (comprised of the year-end market price plus any uninvested cash position). Participant loans are valued at cost, which approximates market value. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded when earned. Dividends are recorded on the ex-dividend date. Capital gain distributions are included in dividend income. PAYMENT OF BENEFITS Benefits are recorded when paid. 3. INVESTMENTS The Plan's investments (including investments purchased or sold, as well as held during the year) appreciated (depreciated) in fair value as determined by quoted market prices as follows: 2002 2001 --------------------------- (In Thousands) Mutual funds $ (30,368) $ (20,927) Peabody Energy Stock Fund 327 46 --------------------------- $ (30,041) $ (20,881) =========================== 8 Peabody Holding Company, Inc. Employee Retirement Account Notes to Financial Statements (continued) 3. INVESTMENTS (CONTINUED) Investments that represent 5% or more of the fair value of the Plan's net assets at December 31 are as follows: 2002 2001 ------------------------- (In Thousands) Mutual funds: Vanguard 500 Index Fund $ 36,822 $ 47,842 Vanguard PRIMECAP Fund 14,933 20,163 Common/collective trust: Vanguard Retirement Savings Trust 84,965 78,113 4. INCOME TAX STATUS The Plan has received a determination letter from the Internal Revenue Service (IRS) dated September 29, 1995 stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the Code) and, therefore, the related trust is exempt from taxation. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan was amended subsequent to the IRS determination letter. The Plan's administrator believes the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes the Plan is qualified and the related trust is tax-exempt. The Plan's sponsor has indicated that it will take the necessary steps, if any, to maintain the Plan's qualified status. 9 Supplemental Schedule Peabody Holding Company, Inc.
