1. DESCRIPTION OF THE PLAN

The following description of the Lee Ranch Coal Company (the Company) Retirement
and Savings Plan for Salaried 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 salaried 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 Salaried 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 at 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 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 makes matching contributions of 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. Matching
contributions are made in cash each pay period, and are invested according to
the employee's investment elections.




                                                                               3

               Notes to Unaudited Financial Statements (continued)


1. DESCRIPTION OF THE PLAN (CONTINUED)

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.

VESTING

Participants are vested immediately in their contributions plus actual earnings
thereon. Vesting in employer matching contributions is based on years of
continuous service. Employer matching contributions become 20 percent vested for
each year of service until 100 percent vested after the fifth year of service. A
year of service is defined as any 12-month period during which the employee
completes at least 1,000 hours 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.

FORFEITED ACCOUNTS

Employer contributions are reduced by forfeitures of non-vested amounts. The
forfeiture credits amount to $2,768 and $5,548 for the years ended December 31,
2001 and 2000, respectively.

1. DESCRIPTION OF THE PLAN (CONTINUED)

PLAN TERMINATION

Although there has been no expressed intention to do so, the Company has the
right to terminate the Plan subject to the provisions of ERISA. In the event of
plan termination, as defined, each participant would become fully vested in the
employer matching contributions.

ADMINISTRATIVE EXPENSES

The administrative expenses of the Plan are paid by the Company.

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. Participant loans are valued at cost, which
approximates market value.

Purchases and sales are recorded on a trade date basis. Interest income is
recorded when earned. Dividends are recorded on the ex-dividend date.

4. INCOME TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service
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 administrator believes the
Plan is being operated in compliance with the applicable requirements of the
Code and, therefore, believes that the Plan is qualified and the related trust
is tax exempt. The Plan has applied for a new determination letter.

5. 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.
