                         Report of Independent Auditors

Plan Administrators and Participants
Lee Ranch Coal Company Retirement and
   Savings Plan for Hourly Employees

We have audited the accompanying statements of net assets available for benefits
of Lee Ranch Coal Company Retirement and Savings Plan for Hourly Employees as of
December 31, 2001 and 2000, 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, 2001 and 2000, 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, 2001 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.

1. DESCRIPTION OF THE PLAN

The following description of the Lee Ranch Coal Company (the Company) Retirement
and Savings Plan for Hourly Employees (the Plan) provides only general
information. Participants should refer to the plan document for a more complete
description of the Plan's provisions.

GENERAL

The Plan is a defined contribution plan covering all hourly employees of the
Company who have completed 30 days of service and all employees that previously
participated in the Santa Fe Pacific Coal Company Retirement and Savings Plan
for Hourly Employees. It is subject to the provisions of the Employee Retirement
Income Security Act of 1974 (ERISA). Effective January 1, 2001, employees are
eligible for participation in the Plan on the date of their employment or any
time afterward.

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 up to 16 percent of pretax or after-tax
annual compensation, as defined in the Plan. Participants direct the investment
of their contributions into various investment options offered by the Plan. The
Company makes matching contributions of an amount equal to 100 percent of the
first 3 percent of compensation that a participant contributes to the Plan on a
pretax basis. Participants direct the investment of employer matching
contributions. All contributions are subject to certain limitations.

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 earnings 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.



                                                                               4

                    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 contribution portion of their accounts is based
on years of continuous service. Employer matching contributions become 20
percent vested for each year of service, as defined, with 100 percent vesting
after five years of service.

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 percent of their 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.

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 or annual installments. 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. A
participant may also elect to take a withdrawal of all or a portion of his or
her employee after-tax contribution account after being a participant for three
months. This withdrawal cannot be made more than once in any three-month period.
Withdrawals in cases of hardship, as defined in the Plan, are also permitted.

FORFEITED ACCOUNTS

Employer contributions are reduced by forfeitures of non-vested amounts. The
forfeiture credits amounted to $0 and $4,278 for the years ended December 31,
2001 and 2000, respectively.

PLAN TERMINATION

Although it has not expressed any 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



                                                                               5

provisions of ERISA. In the event of plan termination, participants' accounts
become fully vested.

ADMINISTRATIVE EXPENSES

Most administrative expenses of the Plan are paid by the Company. Loan fees are
paid by participants.

OTHER EXPENSES

Other expenses amounted to $2,245 and $5,178 for the years ended December 31,
2001 and 2000, respectively. These amounts consisted of administrative expenses
of approximately $2,245 and $900 and interdivisional forfeiture transfers of $0
and $4,278 for the years ended December 31, 2001 and 2000, respectively.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF ACCOUNTING

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 revenue and expenses during the
reporting period. Actual results could differ from these estimates.

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



                                                                               6

                    Notes to Financial Statements (continued)


4. INCOME TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service
(IRS) dated January 2, 1996, 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 has applied for a new determination letter.

5. TRANSFERS TO OTHER PLAN

The amount payable to another plan at December 31, 2000 represents participant
account balances that were transferred to the Lee Ranch Coal Company Retirement
and Savings Plan for Salaried Employees.

6. SUBSEQUENT EVENTS

Effective April 1, 2002, participants may contribute, subject to limitations of
applicable law, up to 50 percent of pretax or after-tax annual compensation, as
defined in the Plan.

Also 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.

Beginning April 1, 2002, the Company match was increased to an amount equal to
100 percent of the first 4 percent of compensation that a participant
contributes to the Plan on a pretax basis. After a participant's pretax
contributions reach the pretax limit established by the IRS, the Company matches
an amount equal to 100 percent of the first 4 percent of compensation that a
participant contributes to the Plan on an after-tax basis.
