                           PEABODY ENERGY CORPORATION

     We are the largest private sector coal company in the world. Our sales of
197.9 million tons of coal in 2002 accounted for 17.9% of all U.S. coal sales
and were more than 70% greater than the sales of our closest U.S. competitor.
During the period, we sold coal to more than 280 electric generating and
industrial plants, fueling the generation of more than 9% of all electricity in
the United States and 2% of all electricity in the world. At December 31, 2002,
we had 9.1 billion tons of proven and probable coal reserves, approximately
double the reserves of any other U.S. coal producer. During 2002, our total
revenues, net income, net cash provided by operating activities and Adjusted
EBITDA (as defined in "Summary Financial and Operating Data") were $2.7 billion,
$105.5 million, $231.2 million and $406.1 million, respectively.

     We own majority interests in 33 coal operations located throughout all
major U.S. coal producing regions, with 73% of our U.S. 2002 coal sales shipped
from the western United States and the remaining 27% from the eastern United
States. Most of our production in the western United States is low sulfur coal
from the Powder River Basin, the largest and fastest-growing major U.S.
coal-producing region. Our overall western U.S. coal production has increased
from 37.0 million tons in fiscal year 1990 to 128.0 million tons during 2002,
representing a compounded annual growth rate of 11%. In the West, we own and
operate mines in Arizona, Colorado, Montana, New Mexico and Wyoming. In the
East, we own and operate mines in Illinois, Indiana, Kentucky and West Virginia.
We produced 78% of our 2002 sales volume from non-union mines.

     During 2002, 94% of our sales were to U.S. electricity generators. The U.S.
coal industry continues to fuel more electricity generation than all other
energy sources combined. In 2001, coal-fueled plants generated an estimated 51%
of the nation's electricity, followed by nuclear (20%), gas-fired (17%) and
hydroelectric (6%) units. We believe that competition for cost-efficient energy
will strengthen the demand for coal. We also believe that U.S. and world coal
consumption will continue to increase as coal-fueled generating plants utilize
their existing excess capacity and as new coal-fueled plants are constructed.
Coal is an attractive fuel for electricity generation because it is:

          - Abundant:  Coal makes up more than 85% of fossil fuel reserves in
            the United States. The nation has an estimated 250-year supply of
            coal, based on current usage rates.

          - Low-Cost:  At an average delivered price of $1.23 per million
            British thermal units, or Btu, in 2001, and $1.22 in 2002, coal's
            cost advantage over natural gas is significant. The delivered price
            of natural gas averaged $4.49 per million Btu in 2001 and $3.65 in
            2002, while market prices have recently exceeded $10.00. In 2001, 20
            of the 25 lowest cost major generating plants in the United States
            were coal-fueled.

          - Increasingly Clean:  Aggregate emissions from U.S. coal-fueled
            plants have declined significantly since 1970, even as coal
            consumption by electricity generators has more than tripled.

     Approximately 97% of our coal sales during 2002 were under long-term
contracts. As of December 31, 2002, our sales backlog, including backlog subject
to price reopener and/or extension provisions, approximated one billion tons.
The remaining terms of our long-term contracts range from one to 18 years and
have an average volume weighted remaining term of approximately 4.4 years. As of
December 31, 2002, we had entered into commitments to sell 170 million tons, or
approximately 95%, of our expected 2003 coal production and 120 million tons, or
approximately 61%, of our expected 2004 coal production.

                                       S-2


     In addition to our mining operations, our other energy-related businesses
include marketing, brokering and trading coal and emissions allowances, coalbed
methane production, transportation-related services, third-party coal contract
restructuring and the development of coal-fueled generating plants.

COMPETITIVE STRENGTHS

     We believe our strengths will enable us to enhance our industry-leading
position and increase shareholder value.

     - We are the world's largest private-sector producer and marketer of coal
       and the largest reserve holder of any U.S. coal company.

     - We are the largest producer and marketer of low sulfur coal in the United
       States, with the number one position in the Powder River Basin, the
       fastest growing U.S. coal producing region.

     - We have a large portfolio of long-term coal supply agreements that are
       complemented by available production in attractive markets for sale at
       market prices.

     - We are one of the most productive and lowest-cost producers of coal in
       the United States.

     - We serve a broad range of high quality customers with mining operations
       located throughout all major U.S. coal producing regions.

     - Our emphasis on innovative research and development has increased our
       productivity.

     - We are a leader in reclamation management and have received numerous
      state and national awards for our commitment to environmental excellence.

     - Our management team has a proven record of success.

TRANSFORMATION OF PEABODY

     Since 1990, we have grown significantly and our management has transformed
our company from a largely high sulfur, high-cost coal company to a
predominantly low sulfur, low-cost coal producer, marketer and trader. We have
increased our sales of low sulfur coal from 57% of our total volume in 1990 to
77% in 2002. We are also well positioned to continue selling higher sulfur coal
to customers that invest in emissions control technology, buy emissions
allowances or blend higher sulfur coal with low sulfur coal. Our average cost
per ton sold decreased 42% from 1990 to 2002. The following chart demonstrates
our transformation:

BUSINESS STRATEGIES

     Our transformation discussed above has resulted in part from the successful
implementation of our three core business strategies:

     - Managing safe, low-cost operations.

     - Adding value through world-class sales, brokerage and trading techniques.

     - Aggressively managing our vast natural resource position.

RECENT DEVELOPMENTS

     Results for the Quarter Ended March 31, 2003.  We recently reported results
for the fiscal quarter ended March 31, 2003. We reported a net loss of $11.2
million, or $0.21 per share. Income was $20.2 million, or $0.39 per share,
before $21.2 million in early debt extinguishment charges and $10.2 million in
charges related to the cumulative effect of accounting changes for the quarter
ended March 31, 2003.

     Revenues of $681.2 million were comparable with the prior year, as higher
pricing overcame reduced production related to customer outages. Heavy snowfall
in Appalachia and the Powder River Basin also disrupted production and reduced
shipments.

     First quarter Adjusted EBITDA of $97.0 million exceeded first quarter
targets of $80 to $90 million, compared with $113.7 million in 2002. We operated
below optimal levels to accommodate multiple customer outages, experienced
temporary geologic issues at an Appalachian mine and incurred start-up costs at
two Midwestern mines.

     Adjusted EBITDA is calculated as follows (unaudited):

     First quarter Adjusted EBITDA benefited from our Australian operation
purchased in August of 2002 and improved results from the resource management
business. Operating profit of $34.5 million included the above factors, and was
also reduced by approximately $11 million in mostly non-cash expenses. These
expenses related to higher health care and pensions and the adoption of
Statement of Financial Accounting Standard 143 (SFAS 143), the new accounting
standard for recording post-mining reclamation liabilities.

     Income, excluding several special items in the first quarter, totaled $20.2
million, or $0.39 per share. The special items included:

     - A charge of $21.2 million ($0.41 per share) related to the early
       extinguishment of debt. We expect a second quarter charge of
       approximately $31 million ($0.59 per share) in additional early debt
       extinguishment expenses when our remaining higher-cost bonds are
       redeemed; and

                                       S-4


     - A net charge of $10.2 million ($0.19 per share) for the cumulative
       effects of accounting changes, primarily related to a $9.1 million
       non-cash cumulative-effect gain due to the adoption of SFAS 143,
       "Accounting for Asset Retirement Obligations," and a $20.2 million
       non-cash cumulative-effect charge related to new accounting standards for

     In early 1999, we increased our equity interest in Black Beauty from 43.3%
to 81.7%. Our results of operations include the consolidated results of Black
Beauty, effective January 1, 1999. Prior to that date, we accounted for our
investment in Black Beauty under the equity method, under which we reflected our
share of Black Beauty's results of operations as a component of "Other revenues"
in the statements of operations, and our interest in Black Beauty's net assets
within "Investments and other assets" in the balance sheets.

     In anticipation of the sale of Citizens Power, our power marketing
subsidiary, which occurred in August 2000, we classified Citizens Power as a
discontinued operation as of March 31, 2000, and recorded an estimated loss on
the sale of $78.3 million, net of income taxes. We have adjusted our results of
operations to reflect the classification of Citizens Power as a discontinued
operation for all periods presented.

     Results of operations for the year ended March 31, 2000 included a $144.0
million income tax benefit associated with an increase in the tax basis of a
subsidiary's assets due to a change in federal income tax regulations.

     On January 29, 2001, we sold our Australian operations. The following
summary financial and other data includes results of operations from these
Australian operations prior to the date of sale and also includes the gain on
this sale. Results of operations for the year ended March 31, 2001 included a
pretax gain of $171.7 million, or $124.2 million net of income taxes, from the
sale of our Australian operations. In August 2002, we re-entered Australia by
purchasing a coal mine in Queensland.

     In connection with our initial public offering in May 2001, we converted
our preferred stock and our Class A common stock and Class B common stock to a
single class of common stock, all on a one-for-one basis.

     Results of operations for the year ended December 31, 2002 included an
income tax benefit of $40.0 million. This benefit resulted primarily from
significant tax benefits realized as a result of utilizing net operating loss
carryforwards to offset taxable gains recognized in connection with property
sale transactions. Utilization of the loss carryforwards required the reduction
of a previously recorded valuation allowance that had reduced the book value of
the loss carryforwards. Also in 2002, due to a change in accounting principle,
we began recording revenues related to all coal trading activities on a net
basis in "Other revenues," and all prior period amounts were reclassified. Had
our physically settled trading transactions been recorded on a gross basis,
total revenues and operating costs would have been $41.6 million, $88.8 million
and $161.9 million higher for the year ended March 31, 2001, the nine months
ended December 31, 2001 and the year ended December 31, 2002, respectively.

(1) EBITDA, a measure used by management to measure operating performance, is
    defined as income from continuing operations before deducting net interest
    expense, income taxes, depreciation, depletion and amortization. EBITDA is
    further adjusted to exclude minority interests to arrive at Adjusted EBITDA.
    We believe that the supplementary adjustment to EBITDA is appropriate to
    provide additional information to investors about our ability to meet debt
    service and capital expenditure requirements. We believe that the amounts
    shown for Adjusted EBITDA as presented in this prospectus supplement are not
    materially different from the amounts calculated under the definition of
    Consolidated Cash Flow used in the indentures for the senior notes and the
    senior subordinated notes.

                                       S-8


    EBITDA and Adjusted EBITDA are not recognized terms under GAAP and do not
    purport to be alternatives to operating income, net income or cash flows
    from operating activities as determined in accordance with GAAP as a measure
    of profitability or liquidity. Because not all companies use identical
    calculations, these presentations of EBITDA and Adjusted EBITDA may not be
    comparable to other similarly titled measures of other companies.
    Additionally, EBITDA and Adjusted EBITDA are not intended to be measures of
    free cash flow for management's discretionary use, as they do not consider
    certain cash requirements such as interest payments, tax payments and debt
    service requirements.

     EBITDA and Adjusted EBITDA are calculated as follows (unaudited):

     Under the terms of an underwriting agreement, which will be filed as an
exhibit to a current report on Form 8-K and incorporated by reference into this
prospectus supplement and the accompanying prospectus, each of Lehman Brothers
Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Morgan Stanley & Co.
Incorporated, Bear, Stearns & Co. Inc. and A.G. Edwards & Sons, Inc. have
severally agreed to purchase from the selling stockholders the respective number
of shares of common stock opposite their names below:



                                                                  NUMBER OF

     The underwriting agreement provides that the underwriters' obligation to
purchase shares of common stock depends on the satisfaction of the conditions
contained in the underwriting agreement, namely:

     - the obligation to purchase all of the shares hereby, if any of the shares
       are purchased;

     - the representations and warranties made by us and the selling
       stockholders to the underwriters are true;

     - there is no material change in the financial markets; and

     - we and the selling stockholders deliver customary closing documents to
       the underwriters.

  Over-Allotment Option

     Certain of the selling stockholders have granted the underwriters a 30-day
option to purchase up to 750,000 shares at the public offering price less
underwriting discounts and commissions. This option may be exercised to cover
over-allotments, if any. To the extent that the option is exercised, each
underwriter will be obligated, subject to certain conditions, to purchase a
number of additional shares proportionate to the underwriter's initial
commitment as indicated in the preceding table, and the selling stockholders
will be obligated, pursuant to the option, to sell these shares to the
underwriters.

  Commissions and Expenses

     The underwriters have advised us and the selling stockholders that the
underwriters propose to offer shares of common stock directly to the public at
the public offering price on the cover of this prospectus supplement and to
selected dealers, who may include the underwriters, at such offering price less
a selling concession not in excess of $   per share. The underwriters may allow,
and the selected dealers may re-allow, a discount from the concession not in
excess of $   per share to other dealers. After the offering, the underwriters
may change the public offering price and other offering terms.

     The following table summarizes the underwriting discounts and commissions
the selling stockholders will pay to the underwriters. These amounts are shown
assuming both no exercise and full exercise of the underwriters' over-allotment
option to purchase up to 750,000 additional shares. The underwriting fee is the
difference between the initial price to the public and the amount the
underwriters pay the selling stockholders for the shares.

     We estimate that the total expenses of the offering, excluding underwriting
discounts and commissions, will be approximately $          . We have agreed to
pay expenses incurred in connection

                                       S-11


with the offering that are customarily paid by the registering company. We will
not pay any underwriting discounts or commissions.

  Listing

     Our common stock is traded on the New York Stock Exchange under the symbol
"BTU."

  Stabilization, Short Positions and Penalty Bids

     The underwriters may engage in over-allotment, stabilizing transactions,
syndicate covering transactions, and penalty bids or purchases for the purpose
of pegging, fixing or maintaining the price of the common stock, in accordance
with Regulation M under the Securities Exchange Act of 1934, as amended:

     - Over-allotment involves sales by the underwriter of shares in excess of
       the number of shares the underwriter is obligated to purchase, which
       creates a syndicate short position. The short position may be either a
       covered short position or a naked short position. In a covered short
       position, the number of shares over-allotted by the underwriter is not
       greater than the number of shares that they may purchase in the
       over-allotment option. In a naked short position, the number of shares
       involved is greater than the number of shares in the over-allotment
       option. The underwriter may close out any short position by either
       exercising its over-allotment option and/or purchasing shares in the open
       market.

     - Stabilizing transactions permit bids to purchase the underlying security
       so long as the stabilizing bids do not exceed a specified maximum.

     - Syndicate covering transactions involve purchases of the common stock in
       the open market after the distribution has been completed in order to
       cover syndicate short positions. In determining the source of shares to
       close out the short position, the underwriter will consider, among other
       things, the price of shares available for purchase in the open market as
       compared to the price at which they may purchase shares through the
       over-allotment option. If the underwriter sells more shares than could be
       covered by the over-allotment option, which is called a naked short
       position, the position can only be closed out by buying shares in the
       open market. A naked short position is more likely to be created if the
       underwriter is concerned that there could be downward pressure on the
       price of the shares in the open market after pricing that could adversely
       affect investors who purchase shares in the offering.

     - Penalty bids permit the underwriters to reclaim a selling concession from
       a syndicate member when the common stock originally sold by the syndicate
       member is purchased in a stabilizing or syndicate covering transaction to
       cover syndicate short positions.

     These stabilizing transactions, syndicate covering transactions and penalty
bids may have the effect of raising or maintaining the market price of the
common stock or preventing or retarding a decline in the market price of the
common stock. As a result, the price of the common stock may be higher than the
price that might otherwise exist in the open market. These transactions may be
effected on the New York Stock Exchange or otherwise and, if commenced, may be
discontinued at any time.

     Neither we, the selling stockholders, nor any of the underwriters make any
representation or prediction as to the direction or magnitude of any effect that
the transactions described above may have on the price of the common stock. In
addition, neither we, the selling stockholders, nor the underwriters make any
representation that the underwriters will engage in these stabilizing
transactions or that any transaction, once commenced, will not be discontinued
without notice.

  Lock-Up Agreements

     We have agreed that we will not offer, sell, contract to sell, pledge or
otherwise dispose of, directly or indirectly, or file with the SEC a
registration statement under the Securities Act relating to, any shares of our
common stock or securities convertible into or exchangeable or exercisable for
any shares of our common stock, or publicly disclose the intention to make any
such offer, sale, pledge, disposition or filing, without the prior written
consent of Lehman Brothers Inc. for a period of 60 days after the date of this
prospectus supplement, except issuances pursuant to the exercise of options
outstanding on the date hereof,

                                       S-12


grants of employee stock options pursuant to the terms of a plan in effect on
the date hereof, issuances pursuant to the exercise of such options, the filing
of registration statements on Form S-8 and amendments thereto in connection with
those stock options or our employee stock purchase plans in existence on the
date hereof and the issuance of shares or options in acquisitions in which the
acquiror of such shares agrees to the foregoing restrictions.

     Certain of the selling stockholders and certain of our executive officers
have agreed under lock-up agreements that without the prior written consent of
Lehman Brothers Inc., they will not offer, sell or otherwise dispose of any
shares of capital stock or any securities which may be converted into or
exchanged for any shares of capital stock for a period ending 60 days after the
date of this prospectus supplement, other than the common stock sold under this
prospectus supplement. Notwithstanding the foregoing, employees subject to the
lock-up arrangement previously described will be permitted to exercise options
to acquire, and sell, up to an aggregate of 450,000 shares of common stock
during the 60-day period following the date of this prospectus.

  Indemnification

     We and the selling stockholders have agreed to indemnify the underwriters
against liabilities relating to the offering, including liabilities under the
Securities Act and liabilities arising from breaches of the representations and
warranties contained in the underwriting agreement, and to contribute to
payments that the underwriters may be required to make for these liabilities.

  Stamp Taxes

     Purchasers of the shares of our common stock offered by this prospectus
supplement may be required to pay stamp taxes and other charges under the laws
and practices of the country of purchase, in addition to the offering price
listed on the cover of this prospectus supplement. Accordingly, we urge you to
consult a tax advisor with respect to whether you may be required to pay those
taxes or charges, as well as any other tax consequences that may arise under the
laws of the country of purchase.

  Notice to Canadian Investors

       Resale Restrictions

     The distribution of the securities in Canada is being made only on a
private placement basis exempt from the requirement that we prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of securities are made. Any resale of the securities in Canada must be
made under applicable securities laws which will vary depending on the relevant
jurisdiction, and which may require resales to be made under available statutory
exemptions or under a discretionary exemption granted by the applicable Canadian
securities regulatory authority. Purchasers are advised to seek legal advice
prior to any resale of the securities.

       Representations of Purchasers

     By purchasing securities in Canada and accepting a purchase confirmation, a
purchaser is representing to us and the dealer from whom the purchase
confirmation is received that:

     - the purchaser is entitled under applicable provincial securities laws to
       purchase the securities without the benefit of a prospectus qualified
       under those securities laws;

     - where required by law, that the purchaser is purchasing as principal and
       not as agent; and

     - the purchaser has reviewed the text in the above under "Resale
       Restrictions".

       Rights of Actions -- Ontario Purchasers

     Under Ontario securities legislation, a purchaser who purchases a security
offered by this prospectus during the period of distribution will have a
statutory right of action for damages, or while still the owner of the shares,
for rescission against us in the event that this prospectus contains a
misrepresentation. A purchaser will be deemed to have relied on the
misrepresentation. The right of action for damages is exercisable not later than
the earlier of 180 days from the date the purchaser first had knowledge of the

                                       S-13


facts giving rise to the cause of action and three years from the date on which
payment is made for the shares. The right of action for rescission is
exercisable not later than 180 days from the date on which payment is made for
the shares. If a purchaser elects to exercise the right of action for
rescission, the purchaser will have no right of action for damages against us.
In no case will the amount recoverable in any action exceed the price at which
the shares were offered to the purchaser and if the purchaser is shown to have
purchased the securities with knowledge of the misrepresentation, we will have
no liability. In the case of an action for damages, we will not be liable for
all or any portion of the damages that are proven to not represent the
depreciation in value of the shares as a result of the misrepresentation relied
upon. These rights are in addition to, and without derogation from, any other
rights or remedies available at law to an Ontario purchaser. The foregoing is a
summary of the rights available to an Ontario purchaser. Ontario purchasers
should refer to the complete text of the relevant statutory provisions.

       Enforcement of Legal Rights

     All of our directors and officers as well as the experts named herein may
be located outside of Canada and, as a result, it may not be possible for
Canadian purchasers to effect service of process within Canada upon us or those
persons. All or a substantial portion of our assets and the assets of those
persons may be located outside of Canada and, as a result, it may not be
possible to satisfy a judgment against us or those persons in Canada or to
enforce a judgment obtained in Canadian courts against us or those persons
outside of Canada.

       Taxation and Eligibility for Investment

     Canadian purchasers of securities should consult their own legal and tax
advisors with respect to the tax consequences of an investment in the securities
in their particular circumstances and about the eligibility of the securities
for investment by the purchaser under relevant Canadian legislation.

  Electronic Distribution

     A prospectus in electronic format may be made available on the Internet
sites or through other online services maintained by the underwriters and/or one
or more of the selling group members participating in this offering, or by their
affiliates. In those cases, prospective investors may view offering terms online
and, depending upon the underwriter or the particular selling group member,
prospective investors may be allowed to place orders online. The underwriters
may agree with us to allocate a specific number of shares for sale to online
brokerage account holders. Any such allocation for online distributions will be
made by the underwriters on the same basis as other allocations.

     Other than the prospectus in electronic format, the information on the
underwriters' or any selling group member's web site and any information
contained in any other web site maintained by the underwriter or any selling
group member is not part of the prospectus supplement, the accompanying
prospectus or the registration statement of which this prospectus supplement and
the accompanying prospectus form a part, has not been approved and/or endorsed
by us or the underwriters or any selling group member in its capacity as
underwriter or selling group member and should not be relied upon by investors.

  Our Relationships with the Underwriters/NASD Conduct Rule

also affiliated with Lehman Brothers Inc. Mr. Goodspeed is an Advisory Director

Lehman Brothers Inc.

     Lehman Brothers Inc. and its affiliates have performed and expect to
continue to perform financial advisory investment banking services for us for
which they have received and will receive customary compensation. Lehman
Brothers Merchant Banking Partners II L.P. and other of its affiliates
(collectively, the "Lehman Selling Stockholders"), each of which is an affiliate
of Lehman Brothers Inc., are selling stockholders in this offering and,
together, beneficially own more than 10% of our common stock and will receive

senior subordinated notes, and is currently serving as the dealer manager in
connection with the offer to purchase those notes. Lehman

                                       S-14


Brothers Inc. served as the lead underwriter in connection with the initial
public offering of our common stock. In April 2002, Lehman Brothers served as
the lead underwriter in connection with the offering of our common stock by the
Lehman Selling Stockholders and certain other selling stockholders. Lehman
Commercial Paper Inc. will serve as a joint lead arranger, joint book-running
manager and syndication agent in connection with our new credit facility.
Because of these relationships, the offering is being conducted in accordance
with Rule 2720 of the National Association of Securities Dealers, or NASD.

does not require that we use a qualified independent underwriter for this
offering.

not intend to confirm sales to discretionary accounts over which they have
discretionary authority without the prior written approval of the customer.

                                  THE COMPANY

     We are the largest private-sector coal company in the world. During the
nine months ended September 30, 2002, we sold 147.9 million tons of coal. During
this period, we sold coal to more than 280 electric generating and industrial
plants, fueling the generation of more than 9% of all electricity in the United
States and 2.5% of all electricity in the world. At September 30, 2002, we had
9.0 billion tons of proven and probable coal reserves in the U.S., approximately
double the reserves of any other U.S. coal producer.

     We own majority interests in 35 coal operations located throughout all
major U.S. coal producing regions, with 73% of our U.S. mining operation's coal
sales in the nine months ended September 30, 2002 shipped from the western
United States and the remaining 27% from the eastern United States. Most of our
production in the western United States is low sulfur coal from the Powder River
Basin. Our overall western U.S. coal production increased from 37.0 million tons
in fiscal year 1990 to 127.1 million tons in calendar year 2001, representing a
compounded annual growth rate of 12%. In the west, we own and operate mines in
Arizona, Colorado, Montana, New Mexico and Wyoming. In the east, we own and
operate mines in Illinois, Indiana, Kentucky and West Virginia. We produced 78%
of our sales volume in the nine months ended September 30, 2002 from non-union
mines.

     For the nine months ended September 30, 2002, 93% of our sales were to U.S.
electricity generators, 4% were to the U.S. industrial sector and the remainder
were to customers outside the United States. Approximately 97% of our coal sales
during the nine months ended September 30, 2002 were under long-term contracts.
As of September 30, 2002, nearly one billion tons of our future coal production
were committed under long-term contracts, with remaining terms ranging from one
to 18 years and an average volume-weighted remaining term of approximately 4.5
years. As of December 31, 2002, we had nine million tons and 76 million tons of
expected production available for sale at market-based prices in calendar year
2003 and 2004, respectively. We have the ability to increase production by 15 to
20 million tons annually within three to six months by running our current
operations at their full capacity.

     In addition to our mining operations, we market, broker and trade coal and
emission allowances. Our total tons traded were 55.8 million for the nine months
ended September 30, 2002. Our other related energy related businesses include
coalbed methane production, transportation-related services, third-party coal
contract restructuring and the development of coal-fueled generating plants.

     Our principal executive offices are located at 701 Market Street, St.
Louis, Missouri 63101-1826, telephone (314) 342-3400.

                                  RISK FACTORS

     An investment in our common stock involves risks. You should consider
carefully, in addition to the other information contained in this prospectus,
the following risk factors before deciding to purchase any common stock.

RISKS RELATING TO OUR COMPANY

IF A SUBSTANTIAL PORTION OF OUR LONG-TERM COAL SUPPLY AGREEMENTS TERMINATE, OUR
REVENUES AND OPERATING PROFITS COULD SUFFER IF WE WERE UNABLE TO FIND ALTERNATE
BUYERS WILLING TO PURCHASE OUR COAL ON COMPARABLE TERMS TO THOSE IN OUR
CONTRACTS.

     A substantial portion of our sales are made under coal supply agreements,
which are important to the stability and profitability of our operations. The
execution of a satisfactory coal supply agreement is frequently the basis on
which we undertake the development of coal reserves required to be supplied
under the contract. For the nine months ended September 30, 2002, 97% of our
sales volume was sold under long-term coal supply agreements. At September 30,
2002, our coal supply agreements had remaining terms ranging from one to 18
years and an average volume-weighted remaining term of approximately 4.5 years.

     Many of our coal supply agreements contain provisions that permit the
parties to adjust the contract price upward or downward at specified times. We
may adjust these contract prices based on inflation and/or changes in the
factors affecting the cost of producing coal, such as taxes, fees, royalties and
changes in the laws regulating the mining, production, sale or use of coal. In a
limited number of contracts, failure of the parties to agree on a price under
those provisions may allow either party to terminate the contract. We have also
experienced a similar reduction in coal prices in new long-term coal supply
agreements replacing some of our expiring contracts. Coal supply agreements also
typically contain force majeure provisions allowing temporary suspension of
performance by us or the customer during the duration of specified events beyond
the control of the affected party. Most coal supply agreements contain
provisions requiring us to deliver coal meeting quality thresholds for certain
characteristics such as Btu, sulfur content, ash content, grindability and ash
fusion temperature. Failure to meet these specifications could result in
economic penalties, including price adjustments, the rejection of deliveries or
termination of the contracts. Moreover, some of these agreements permit the
customer to terminate the contract if transportation costs, which our customers
typically bear, increase substantially. In addition, some of these contracts
allow our customers to terminate their contracts in the event of changes in
regulations affecting our industry that increase the price of coal beyond
specified limits.

     The operating profits we realize from coal sold under supply agreements
depend on a variety of factors. In addition, price adjustment and other
provisions may increase our exposure to short-term coal price volatility
provided by those contracts. If a substantial portion of our coal supply
agreements were modified or terminated, we could be materially adversely
affected to the extent that we are unable to find alternate buyers for our coal
at the same level of profitability. Some of our coal supply agreements are for
prices above current market prices. Although market prices for coal increased in
most regions in 2001, market prices for coal decreased in most regions in 2002.
As a result, we cannot predict the future strength of the coal market and cannot
assure you that we will be able to replace existing long-term coal supply
agreements at the same prices or with similar profit margins when they expire.
In addition, two of our coal supply agreements are the subject of ongoing
litigation and arbitration.

THE LOSS OF, OR SIGNIFICANT REDUCTION IN, PURCHASES BY OUR LARGEST CUSTOMERS
COULD ADVERSELY AFFECT OUR REVENUES.

     For the nine months ended September 30, 2002, we derived 25% of our total
coal revenues from sales to our five largest customers. At September 30, 2002,
we had 27 coal supply agreements with these customers that expire at various
times from 2003 to 2015. We are currently discussing the extension of existing
agreements or entering into new long-term agreements with some of these
customers, but these negotiations may not be successful and those customers may
not continue to purchase coal from us under

                                        2


long-term coal supply agreements. If a number of these customers were to
significantly reduce their purchases of coal from us, or if we were unable to
sell coal to them on terms as favorable to us as the terms under our current
agreements, our financial condition and results of operations could suffer
materially.

     In addition, we sold 3.4 million tons of coal to the Mohave Generating
Station in the nine months ended September 30, 2002. We have a long-term coal
supply agreement with the owners of the Mohave Generating Station that expires
on December 31, 2005, but may be renewed as provided in the agreement. There is
a dispute with the Hopi Tribe regarding the use of groundwater in the
transportation of coal by pipeline to the Mohave Generating Station. Also,
Southern California Edison (the majority owner and operator of the plant) is
involved in a California Public Utility Commission proceeding related to
recovery of future capital expenditures for new pollution abatement equipment
for the station. As a result of these issues, the owners of the Mohave
Generating Station have announced that they expect to idle the plant for at
least six to 12 months beginning in 2006. We are in active discussions to
resolve the complex issues critical to the continuation of the operation of the
Mohave Generating Station and the renewal of the coal supply agreement after
December 31, 2005. There is no assurance that the issues critical to the
continued operation of the Mohave Generating Station will be resolved. The
Mohave Generating Station is the sole customer of our Black Mesa Mine, which
produces and sells 4.5 to 5 million tons of coal per year. If we are unable to
renew the coal supply agreement with the Mohave Generating Station, our
financial condition and results of operations could be adversely affected after
2005.

OUR FINANCIAL PERFORMANCE COULD BE ADVERSELY AFFECTED BY OUR SUBSTANTIAL DEBT.

     Our financial performance could be affected by our substantial
indebtedness. As of September 30, 2002, we had total indebtedness of $1,047.8
million. We currently have total borrowing capacity under our and Black Beauty's
revolving credit facilities of $490.0 million. We may also incur additional
indebtedness in the future.

     Our ability to pay principal and interest on our debt depends upon the
operating performance of our subsidiaries, which will be affected by, among
other things, prevailing economic conditions in the markets they serve, some of
which are beyond our control. Our business may not generate sufficient cash flow
from operations and future borrowings may not be available under our revolving
credit facilities or otherwise in an amount sufficient to enable us to service
our indebtedness or to fund our other liquidity needs.

     The degree to which we are leveraged could have important consequences,
including, but not limited to: (1) making it more difficult for us to pay
dividends and satisfy our debt obligations; (2) increasing our vulnerability to
general adverse economic and industry conditions; (3) requiring the dedication
of a substantial portion of our cash flow from operations to the payment of
principal of, and interest on, our indebtedness, thereby reducing the
availability of the cash flow to fund working capital, capital expenditures,
research and development or other general corporate uses; (4) limiting our
ability to obtain additional financing to fund future working capital, capital
expenditures, research and development or other general corporate requirements;
(5) limiting our flexibility in planning for, or reacting to, changes in our
business; and (6) placing us at a competitive disadvantage compared to less
leveraged competitors. In addition, our indebtedness subjects us to financial
and other restrictive covenants. Failure by us to comply with these covenants
could result in an event of default which, if not cured or waived, could have a
material adverse effect on us. Furthermore, substantially all of our assets,
except for the assets of Black Beauty Coal Company and its affiliates, secure
our indebtedness under our senior credit facility.

IF TRANSPORTATION FOR OUR COAL BECOMES UNAVAILABLE OR UNECONOMIC FOR OUR
CUSTOMERS, OUR ABILITY TO SELL COAL COULD SUFFER.

     Transportation costs represent a significant portion of the total cost of
coal, and as a result, the cost of transportation is a critical factor in a
customer's purchasing decision. Increases in transportation costs could make
coal a less competitive source of energy or could make some of our operations
less competitive than other sources of coal. Certain coal supply agreements
permit the customer to terminate the contract if the cost of transportation
increases by an amount ranging from 10% to 20% in any given 12-month period.

                                        3


     Coal producers depend upon rail, barge, trucking, overland conveyor and
other systems to deliver coal to markets. While U.S. coal customers typically
arrange and pay for transportation of coal from the mine to the point of use,
disruption of these transportation services because of weather-related problems,
strikes, lock-outs or other events could temporarily impair our ability to
supply coal to our customers and thus could adversely affect our results of
operations. For example, the high volume of coal shipped from all Southern
Powder River Basin mines could create temporary congestion on the rail systems
servicing that region.

RISKS INHERENT TO MINING COULD INCREASE THE COST OF OPERATING OUR BUSINESS.

     Our mining operations are subject to conditions beyond our control that can
delay coal deliveries or increase the cost of mining at particular mines for
varying lengths of time. These conditions include weather and natural disasters,
unexpected maintenance problems, key equipment failures, variations in coal seam
thickness, variations in the amount of rock and soil overlying the coal deposit,
variations in rock and other natural materials and variations in geologic
conditions.

THE GOVERNMENT EXTENSIVELY REGULATES OUR MINING OPERATIONS, WHICH IMPOSES
SIGNIFICANT COSTS ON US, AND FUTURE REGULATIONS COULD INCREASE THOSE COSTS OR
LIMIT OUR ABILITY TO PRODUCE COAL.

     Federal, state and local authorities regulate the coal mining industry with
respect to matters such as employee health and safety, permitting and licensing
requirements, air quality standards, water pollution, plant and wildlife
protection, reclamation and restoration of mining properties after mining is
completed, the discharge of materials into the environment, surface subsidence
from underground mining and the effects that mining has on groundwater quality
and availability. In addition, significant legislation mandating specified
benefits for retired coal miners affects our industry. Numerous governmental
permits and approvals are required for mining operations. We are required to
prepare and present to federal, state or local authorities data pertaining to
the effect or impact that any proposed exploration for or production of coal may
have upon the environment. The costs, liabilities and requirements associated
with these regulations may be costly and time-consuming and may delay
commencement or continuation of exploration or production operations. The
possibility exists that new legislation and/or regulations and orders may be
adopted that may materially adversely affect our mining operations, our cost
structure and/or our customers' ability to use coal. New legislation or
administrative regulations (or judicial interpretations of existing laws and
regulations), including proposals related to the protection of the environment
that would further regulate and tax the coal industry, may also require us or
our customers to change operations significantly or incur increased costs. The
majority of our coal supply agreements contain provisions that allow a purchaser
to terminate its contract if legislation is passed that either restricts the use
or type of coal permissible at the purchaser's plant or results in specified
increases in the cost of coal or its use. These factors and legislation, if
enacted, could have a material adverse effect on our financial condition and
results of operations.

     In addition, the United States and over 160 other nations are signatories
to the 1992 Framework Convention on Climate Change, which is intended to limit
emissions of greenhouse gases, such as carbon dioxide. In December 1997, in
Kyoto, Japan, the signatories to the convention established a binding set of
emission targets for developed nations. Although the specific emission targets
vary from country to country, the United States would be required to reduce
emissions to 93% of 1990 levels over a five-year budget period from 2008 through
2012. Although the United States has not ratified the emission targets and no
comprehensive regulations focusing on U.S. greenhouse gas emissions are in
place, these restrictions, whether through ratification of the emission targets
or other efforts to stabilize or reduce greenhouse gas emissions, could
adversely impact the price of and demand for coal. According to the Energy
Information Administration's Emissions of Greenhouse Gases in the United States
2001, coal accounts for 32% of greenhouse gas emissions in the United States,
and efforts to control greenhouse gas emissions could result in reduced use of
coal if electricity generators switch to sources of fuel with lower carbon
dioxide emissions. Further developments in connection with regulations or other
limits on carbon dioxide emissions could have a material adverse effect on our
financial condition or results of operations.

                                        4


OUR EXPENDITURES FOR POSTRETIREMENT BENEFIT AND PENSION OBLIGATIONS COULD BE
MATERIALLY HIGHER THAN WE HAVE PREDICTED IF OUR UNDERLYING ASSUMPTIONS PROVE TO
BE INCORRECT.

     We provide postretirement health and life insurance benefits to eligible
union and non-union employees. We calculated the total accumulated
postretirement benefit obligation under Statement of Financial Accounting
Standards No. 106, "Employers' Accounting for Postretirement Benefits Other Than
Pensions," which we estimate had a present value of $1,032.4 million as of
September 30, 2002, $70.4 million of which was a current liability. We have
estimated these unfunded obligations based on assumptions described in Note 18
to our audited financial statements incorporated by reference in this
prospectus. If our assumptions do not materialize as expected, cash expenditures
and costs that we incur could be materially higher. Moreover, regulatory changes
could increase our obligations to provide these or additional benefits.

     We are party to an agreement with the Pension Benefit Guaranty Corporation,
or the PBGC, and TXU Europe Limited, an affiliate of our former parent
corporation, under which we are required to make specified contributions to two
of our defined benefit pension plans and to maintain a $37.0 million letter of
credit in favor of the PBGC. If we or the PBGC gives notice of an intent to
terminate one or more of the covered pension plans in which liabilities are not
fully funded, or if we fail to maintain the letter of credit, the PBGC may draw
down on the letter of credit and use the proceeds to satisfy liabilities under
the Employee Retirement Income Security Act of 1974, as amended. The PBGC,
however, is required to first apply amounts received from a $110.0 million
guaranty in place from TXU Europe Limited in favor of the PBGC before it draws
on our letter of credit. On November 19, 2002 TXU Europe Limited was placed
under the administration process in the United Kingdom (a process similar to
bankruptcy proceedings in the United States). As a result of these proceedings,
TXU Europe Limited may be liquidated or otherwise reorganized in such a way as
to relieve it of its obligations under its guaranty.

OUR FUTURE SUCCESS DEPENDS UPON OUR ABILITY TO CONTINUE ACQUIRING AND DEVELOPING
COAL RESERVES THAT ARE ECONOMICALLY RECOVERABLE.

     Our recoverable reserves decline as we produce coal. We have not yet
applied for the permits required or developed the mines necessary to use all of
our reserves. Furthermore, we may not be able to mine all of our reserves as
profitably as we do at our current operations. Our future success depends upon
our conducting successful exploration and development activities or acquiring
properties containing economically recoverable reserves. Our current strategy
includes increasing our reserve base through acquisitions of government and
other leases and producing properties and continuing to use our existing
properties. The federal government also leases natural gas and coalbed methane
reserves in the west, including in the Powder River Basin. Some of these natural
gas and coalbed methane reserves are located on, or adjacent to, some of our
Powder River Basin reserves, potentially creating conflicting interests between
us and lessees of those interests. Other lessees' rights relating to these
mineral interests could prevent, delay or increase the cost of developing our
coal reserves. These lessees may also seek damages from us based on claims that
our coal mining operations impair their interests. Additionally, the federal
government limits the amount of federal land that may be leased by any company
to 150,000 acres nationwide. As of September 30, 2002, we leased or had applied
to lease a total of 66,797 acres from the federal government. The limit could
restrict our ability to lease additional federal lands.

     Our planned development and exploration projects and acquisition activities
may not result in significant additional reserves and we may not have continuing
success developing additional mines. Most of our mining operations are conducted
on properties owned or leased by us. Because title to most of our leased
properties and mineral rights are not thoroughly verified until a permit to mine
the property is obtained, our right to mine some of our reserves may be
materially adversely affected if defects in title or boundaries exist. In
addition, in order to develop our reserves, we must receive various governmental
permits. We cannot predict whether we will continue to receive the permits
necessary for us to operate profitably in the future. We may not be able to
negotiate new leases from the government or from private parties or obtain
mining contracts for properties containing additional reserves or maintain our
leasehold interest in properties on which mining operations are not commenced
during the term of the lease. From time to time, we have experienced litigation
with lessors of our coal properties and with royalty holders.

                                        5


IF THE COAL INDUSTRY EXPERIENCES OVERCAPACITY IN THE FUTURE, OUR PROFITABILITY
COULD BE IMPAIRED.

     During the mid-1970s and early 1980s, a growing coal market and increased
demand for coal attracted new investors to the coal industry, spurred the
development of new mines and resulted in added production capacity throughout
the industry, all of which led to increased competition and lower coal prices.
Similarly, an increase in future coal prices could encourage the development of
expanded capacity by new or existing coal producers. Any overcapacity could
reduce coal prices in the future.

OUR FINANCIAL CONDITION COULD BE NEGATIVELY AFFECTED IF WE FAIL TO MAINTAIN
SATISFACTORY LABOR RELATIONS.

     As of September 30, 2002, the United Mine Workers of America represented
approximately 33% of our employees, who produced 20% of our coal sales volume
during the nine months ended September 30, 2002. An additional 4% of our
employees are represented by labor unions other than the United Mine Workers of
America. These employees produced 3% of our coal sales volume during the nine
months ended September 30, 2002. Because of the higher labor costs and the
increased risk of strikes and other work-related stoppages that may be
associated with union operations in the coal industry, our non-unionized
competitors may have a competitive advantage in areas where they compete with
our unionized operations. If some or all of our current non-union operations
were to become unionized, we could incur an increased risk of work stoppages,
reduced productivity and higher labor costs. The ten-month United Mine Workers
of America strike in 1993 had a material adverse effect on us. Two of our
subsidiaries, Peabody Coal Company and Eastern Associated Coal Corp., operate
under a union contract that is in effect through December 31, 2006. Peabody
Western Coal Company operates under a union contract that is in effect through
September 1, 2005.

OUR OPERATIONS COULD BE ADVERSELY AFFECTED IF WE FAIL TO MAINTAIN REQUIRED
SURETY BONDS.

     Federal and state laws require bonds to secure our obligations to reclaim
lands used for mining, to pay federal and state workers' compensation, to secure
coal lease obligations and to satisfy other miscellaneous obligations. As of
September 30, 2002, we had outstanding surety bonds with third parties for
post-mining reclamation totaling $682.3 million. Furthermore, we had an
additional $194.2 million of surety bonds in place for workers' compensation and
retiree healthcare obligations and $68.8 million of surety bonds securing coal
leases. These bonds are typically renewable on a yearly basis. It has become
increasingly difficult for us to secure new surety bonds or renew bonds without
the posting of partial collateral. In addition, surety bond costs have increased
while the market terms of surety bonds have generally become less favorable to
us. Surety bond issuers and holders may not continue to renew the bonds or may
demand additional collateral upon those renewals. Our failure to maintain, or
inability to acquire, surety bonds that are required by state and federal law
would have a material adverse effect on us. That failure could result from a
variety of factors including the following:

     - lack of availability, higher expense or unfavorable market terms of new
       surety bonds;

     - restrictions on the availability of collateral for current and future
       third-party surety bond issuers under the terms of our indentures or
       senior credit facility; and

     - the exercise by third-party surety bond issuers of their right to refuse
       to renew the surety.

LEHMAN BROTHERS MERCHANT BANKING HAS SIGNIFICANT INFLUENCE ON ALL STOCKHOLDER
VOTES AND MAY HAVE CONFLICTS OF INTEREST WITH OTHER STOCKHOLDERS IN THE FUTURE.

     Prior to the offering of any of the shares offered in this prospectus,
Lehman Brothers Merchant Banking and its affiliates beneficially owned
approximately 41% of our common stock. As a result, Lehman Brothers Merchant
Banking will effectively continue to be able to influence the election of our
directors and determine our corporate and management policies and actions,
including potential mergers or acquisitions, asset sales and other significant
corporate transactions. The interests of Lehman Brothers Merchant Banking may
not coincide with the interests of other holders of our common stock. We have
retained affiliates of Lehman Brothers Merchant Banking to perform advisory and
financing services for us in the past, and may continue to do so in the future.

                                        6


OUR ABILITY TO OPERATE OUR COMPANY EFFECTIVELY COULD BE IMPAIRED IF WE LOSE KEY
PERSONNEL.

     We manage our business with a number of key personnel, the loss of a number
of whom could have a material adverse effect on us. In addition, as our business
develops and expands, we believe that our future success will depend greatly on
our continued ability to attract and retain highly skilled and qualified
personnel. We cannot assure you that key personnel will continue to be employed
by us or that we will be able to attract and retain qualified personnel in the
future. We do not have "key person" life insurance to cover our executive
officers. Failure to retain or attract key personnel could have a material
adverse effect on us.

TERRORIST ATTACKS AND THREATS, ESCALATION OF MILITARY ACTIVITY IN RESPONSE TO
SUCH ATTACKS OR ACTS OF WAR MAY NEGATIVELY AFFECT OUR BUSINESS, FINANCIAL
CONDITION AND RESULTS OF OPERATIONS.

     Terrorist attacks and threats, escalation of military activity in response
to such attacks or acts of war may negatively affect our business, financial
condition and results of operations. Our business is affected by general
economic conditions, fluctuations in consumer confidence and spending, and
market liquidity, which can decline as a result of numerous factors outside of
our control, such as terrorist attacks and acts of war. The 2001 terrorist
attacks in the United States, as well as future events occurring in response to,
or in connection with, the attacks, including future terrorist attacks against
U.S. targets, rumors or threats of war, actual conflicts involving the United
States or its allies, or military or trade disruptions affecting our customers,
may materially adversely affect our operations. As a result, there could be
delays or losses in transportation and deliveries of coal to our customers,
decreased sales of our coal and extension of time for payment of accounts
receivable from our customers. Strategic targets such as energy-related assets
may be at greater risk of future terrorist attacks than other targets in the
United States. In addition, disruption or significant increases in energy prices
could result in government-imposed price controls. It is possible that any, or a
combination, of these occurrences could have a material adverse effect on our
business, financial condition and results of operations.

OUR ABILITY TO COLLECT PAYMENTS FROM OUR CUSTOMERS COULD BE IMPAIRED IF THEIR
CREDITWORTHINESS DETERIORATES.

     Our ability to receive payment for coal sold and delivered depends on the
continued creditworthiness of our customers. Our customer base is changing with
deregulation as utilities sell their power plants to their non-regulated
affiliates or third parties. These new power plant owners may have credit
ratings that are below investment grade. In addition, the creditworthiness of
certain of our customers and trading counterparties has deteriorated due to
lower than anticipated demand for energy and lower volume and volatility in the
traded energy markets in 2002.

     We have taken steps to reduce our credit exposure to customers or
counterparties whose credit has deteriorated and who may pose a higher risk, as
determined by our credit management function, of failure to perform under their
contractual obligations. These steps include obtaining letters of credit, cash
collateral, prepayments for shipments or the creation of customer trust accounts
held for our benefit to fund the payment for coal under existing coal supply
agreements. While these steps can mitigate or eliminate losses related to
existing amounts due from these customers, should a customer become unable to
perform in the future under an existing coal supply agreement, our business
could be adversely affected.

     If deterioration of the creditworthiness of other electric power generator
customers or trading counterparties continues, our $140.0 million accounts
receivable securitization program and our business could be adversely affected.

RISKS RELATED TO THIS REGISTRATION STATEMENT

IF WE OR OUR EXISTING STOCKHOLDERS SELL ADDITIONAL SHARES OF OUR COMMON STOCK
AFTER THE EFFECTIVENESS OF THIS REGISTRATION STATEMENT, THE MARKET PRICE OF OUR
COMMON STOCK COULD DECLINE.

     The market price of our common stock could decline as a result of sales of
a large number of shares of common stock in the public market or the perception
that such sales could occur. These sales, or the

                                        7


possibility that these sales may occur, also might make it more difficult for us
to sell equity securities in the future at a time and at a price that we deem
appropriate.

     Sales of our common stock are restricted by lock-up agreements that our
directors, officers and all of our stockholders who acquired shares prior to our
initial public offering have entered into with us. The lock-up agreements
restrict our directors, certain of our officers and those stockholders, subject
to specified exceptions, from selling or otherwise disposing of any shares for a
period of 14 days prior to and 90 days after the date of any offering under the
registration statement of which this prospectus forms a part without the prior
written consent of the managing underwriter in the context of an underwritten
offering. The managing underwriter, in the case of an underwritten offering may,
however, in its sole discretion and without notice, release all or any portion
of the shares from the restrictions in the lock-up agreements.

     As of January 1, 2003, we had approximately 52.4 million shares of common
stock outstanding. Of those shares, 39.7 million shares will be freely tradeable
if all of the shares registered under this registration statement are sold. Of
the remaining 12.7 million restricted shares, 200,000 may be resold under Rule
144(k) without regard to volume limitations and approximately 12.5 million
shares may be sold subject to the volume, manner of sale and other conditions of
Rule 144. Lehman Brothers Merchant Banking and its affiliates, which will
collectively own 11.3 million shares after the sale of all shares of common
stock being registered under this registration statement, will have the ability
to cause us to register the resale of their shares under their registration
rights agreement.

     In addition, approximately 5.8 million shares are issuable upon the
exercise of presently outstanding stock options under our 1998 Stock Purchase
and Option Plan and our Long-Term Equity Incentive Plan. Shares acquired upon
the exercise of vested options under our 1998 Stock Purchase and Option Plan for
Key Employees will first become eligible for resale in May 2003. In addition,
awards that have been granted under our Long-Term Equity Incentive Plan already
have begun to vest. We plan to file a registration statement to register the
shares issuable upon the exercise of all stock options under our 1998 Stock
Purchase and Option Plan for Key Employees. We filed a registration statement
registering the shares issuable upon the exercise of all stock options under our
Long-Term Equity Incentive Plan on May 22, 2001.

OUR CERTIFICATE OF INCORPORATION AND BY-LAWS INCLUDE PROVISIONS THAT MAY
DISCOURAGE A TAKEOVER ATTEMPT.

     Provisions contained in our certificate of incorporation and by-laws and
Delaware law could make it more difficult for a third party to acquire us, even
if doing so might be beneficial to our stockholders. Provisions of our by-laws
and certificate of incorporation impose various procedural and other
requirements that could make it more difficult for stockholders to effect
certain corporate actions. For example, a change of control of our company may
be delayed or deterred as a result of the stockholders' rights plan adopted by
our board of directors. These provisions could limit the price that certain
investors might be willing to pay in the future for shares of our common stock
and may have the effect of delaying or preventing a change in control.

                                USE OF PROCEEDS

     We will not receive any of the proceeds from the sale of shares by the
selling stockholders. The selling stockholders will receive all net proceeds
from the sale of shares of our common stock offered in this prospectus.

                          DESCRIPTION OF CAPITAL STOCK

     Our authorized capital stock consists of (1) 150 million shares of common
stock, par value $.01 per share, of which 52.4 million shares were outstanding
on January 1, 2003, (2) 10 million shares of preferred stock, par value $.01 per
share, of which no shares are issued or outstanding, (3) 40 million shares of
series common stock, par value $.01 per share, of which no shares are issued or
outstanding and (4) 1.5 million shares of Series A Junior Participating
Preferred Stock of which no shares are issued or outstanding. As of January 2,
2003, there were 123 holders of our common stock. The following description of
our capital stock and related matters is qualified in its entirety by reference
to our certificate of incorporation and by-laws.

     The following summary describes elements of our certificate of
incorporation and by-laws.

COMMON STOCK

     Holders of common stock are entitled to one vote per share on all matters
to be voted upon by the stockholders and vote together, as one class, with the
holders of our Series A Junior Participating Preferred Stock. The holders of
common stock do not have cumulative voting rights in the election of directors.
Holders of common stock are entitled to receive ratably dividends if, as and
when dividends are declared from time to time by our board of directors out of
funds legally available for that purpose, after payment of dividends required to
be paid on outstanding preferred stock or series common stock, as described
below. Upon liquidation, dissolution or winding up, any business combination or
a sale or disposition of all or substantially all of the assets, the holders of
common stock are entitled to receive ratably the assets available for
distribution to the stockholders after payment of liabilities and accrued but
unpaid dividends and liquidation preferences on any outstanding preferred stock
or series common stock. The common stock has no preemptive or conversion rights
and is not subject to further calls or assessment by us. There are no redemption
or sinking fund provisions applicable to the common stock.

SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

     Holders of shares of Series A Junior Participating Preferred Stock are
entitled to receive quarterly dividend payments equal to the greater of $1.00
per share or 100 times the per share dividend declared on our common stock.
Holders of Series A preferred stock are entitled to 100 votes per share on all
matters to be voted upon by the stockholders and vote together, as one class,
with the holders of common stock. Upon liquidation, dissolution or winding up,
holders of our Series A preferred stock are entitled to a liquidation preference
of $100 per share plus all accrued and unpaid dividends and distributions on the
Series A preferred stock or 100 times the amount to be distributed per share on
our common stock, whichever is greater. Liquidation distributions will be made
ratably with all shares ranking on parity with the Series A preferred stock. In
the event of any merger, consolidation, combination or other transaction in
which shares of our common stock are exchanged for other securities, cash or
property, each share of the Series A preferred stock will be exchanged for 100
times the amount received per share on our common stock. Each of these rights of
our Series A preferred stock is protected by customary anti-dilution provisions.
The Series A preferred stock is not redeemable and it will rank junior to any
other series of our preferred stock with respect to the payment of dividends and
the distribution of assets.

PREFERRED STOCK AND SERIES COMMON STOCK

     Our certificate of incorporation authorizes our board of directors to
establish one or more series of preferred stock or series common stock. With
respect to any series of series common stock, our board of directors is
authorized to determine the terms and rights of that series, including:

     - the designation of the series;

     - the number of shares of the series, which our board may, except where
       otherwise provided in the preferred stock or series common stock
       designation, increase or decrease, but not below the number of shares
       then outstanding;

     - whether dividends, if any, will be cumulative or non-cumulative and the
       dividend rate of the series;
                                        10


     - the dates at which dividends, if any, will be payable;

     - the redemption rights and price or prices, if any, for shares of the
       series;

     - the terms and amounts of any sinking fund provided for the purchase or
       redemption of shares of the series;

     - the amounts payable on shares of the series in the event of any voluntary
       or involuntary liquidation, dissolution or winding-up of the affairs of
       our company;

     - whether the shares of the series will be convertible into shares of any
       other class or series, or any other security, of our company or any other
       corporation, and, if so, the specification of the other class or series
       or other security, the conversion price or prices or rate or rates, any
       rate adjustments, the date or dates as of which the shares will be
       convertible and all other terms and conditions upon which the conversion
       may be made;

     - restrictions on the issuance of shares of the same series or of any other
       class or series; and

     - the voting rights, if any, of the holders of the series.

     Unless required by law or by any stock exchange, the authorized shares of
preferred stock and series common stock, as well as shares of common stock, are
available for issuance without further action by you.

     Although we have no intention at the present time of doing so, we could
issue a series of preferred stock or series common stock that could, depending
on the terms of the series, impede the completion of a merger, tender offer or
other takeover attempt. We will make any determination to issue preferred stock
or series common stock based on our judgment as to the best interests of the
company and our stockholders. We, in so acting, could issue preferred stock or
series common stock having terms that could discourage an acquisition attempt or
other transaction that some, or a majority, of you might believe to be in your
best interests or in which you might receive a premium for your common stock
over the market price of the common stock.

AUTHORIZED BUT UNISSUED CAPITAL STOCK

     Delaware law does not require stockholder approval for any issuance of
authorized shares. However, the listing requirements of the New York Stock
Exchange, which would apply so long as the common stock remains listed on the
New York Stock Exchange, require stockholder approval of certain issuances equal
to or exceeding 20% of the then-outstanding voting power or then-outstanding
number of shares of common stock. These additional shares may be used for a
variety of corporate purposes, including future public offerings, to raise
additional capital or to facilitate acquisitions.

     One of the effects of the existence of unissued and unreserved common
stock, preferred stock or series common stock may be to enable our board of
directors to issue shares to persons friendly to current management, which
issuance could render more difficult or discourage an attempt to obtain control
of our company by means of a merger, tender offer, proxy contest or otherwise,
and thereby protect the continuity of our management and possibly deprive the
stockholders of opportunities to sell their shares of common stock at prices
higher than prevailing market prices.

ANTI-TAKEOVER EFFECTS OF PROVISIONS OF DELAWARE LAW AND OUR CHARTER AND BY-LAWS

  Delaware Law

     Our company is a Delaware corporation subject to Section 203 of the
Delaware General Corporation Law. Section 203 provides that, subject to certain
exceptions specified in the law, a Delaware corporation

                                        11


shall not engage in certain "business combinations" with any "interested
stockholder" for a three-year period following the time that the stockholder
became an interested stockholder unless:

     - prior to such time, our board of directors approved either the business
       combination or the transaction which resulted in the stockholder becoming
       an interested stockholder;

     - upon consummation of the transaction which resulted in the stockholder
       becoming an interested stockholder, the interested stockholder owned at
       least 85% of our voting stock outstanding at the time the transaction
       commenced, excluding certain shares; or

     - at or subsequent to that time, the business combination is approved by
       our board of directors and by the affirmative vote of holders of at least
       66 2/3% of the outstanding voting stock which is not owned by the
       interested stockholder.

     Generally, a "business combination" includes a merger, asset or stock sale
or other transaction resulting in a financial benefit to the interested
stockholder. Subject to certain exceptions, an "interested shareholder" is a
person who together with that person's affiliates and associates owns, or within
the previous three years did own, 15% or more of our voting stock.

     Under certain circumstances, Section 203 makes it more difficult for a
person who would be an "interested stockholder" to effect various business
combinations with a corporation for a three-year period. The provisions of
Section 203 may encourage companies interested in acquiring our company to
negotiate in advance with our board of directors because the stockholder
approval requirement would be avoided if our board of directors approves either
the business combination or the transaction which results in the stockholder
becoming an interested stockholder. These provisions also may have the effect of
preventing changes in our board of directors and may make it more difficult to
accomplish transactions which stockholders may otherwise deem to be in their
best interests.

  Certificate of Incorporation; By-laws

     Our certificate of incorporation and by-laws contain provisions that could
make more difficult the acquisition of the company by means of a tender offer, a
proxy contest or otherwise.

     Classified Board.  Our certificate of incorporation provides that our board
of directors will be divided into three classes of directors, with the classes
to be as nearly equal in number as possible. As a result, approximately
one-third of the board of directors will be elected each year. The
classification of directors will have the effect of making it more difficult for
stockholders to change the composition of our board. Our certificate of
incorporation provides that, subject to any rights of holders of preferred stock
or series common stock to elect additional directors under specified
circumstances, the number of directors will be fixed in the manner provided in
our by-laws. Our certificate of incorporation and by-laws provide that the
number of directors will be fixed from time to time exclusively pursuant to a
resolution adopted by the board, but must consist of not less than three
directors. In addition, our certificate of incorporation provides that, subject
to any rights of holders of preferred stock or series common stock and unless
the board otherwise determines, any vacancies will be filled only by the
affirmative vote of a majority of the remaining directors, though less than a
quorum.

     Removal of Directors.  Under Delaware General Corporation Law, unless
otherwise provided in our certificate of incorporation, directors serving on a
classified board may only be removed by the stockholders for cause. In addition,
our certificate of incorporation and by-laws provide that directors may be
removed only for cause and only upon the affirmative vote of holders of at least
75% of the voting power of all the outstanding shares of stock entitled to vote
generally in the election of directors, voting together as a single class.

     Stockholder Action.  Our certificate of incorporation and by-laws provide
that stockholder action can be taken only at an annual or special meeting of
stockholders and may not be taken by written consent in lieu of a meeting. Our
certificate of incorporation and by-laws provide that special meetings of
stockholders can be called only by our chief executive officer or pursuant to a
resolution adopted by our

                                        12


board of directors. Stockholders are not permitted to call a special meeting or
to require that the board of directors call a special meeting of stockholders.

     Advance Notice Procedures.  Our by-laws establish an advance notice
procedure for stockholders to make nominations of candidates for election as
directors, or bring other business before an annual or special meeting of our
stockholders. This notice procedure provides that only persons who are nominated
by, or at the direction of our board of directors, the chairman of the board, or
by a stockholder who has given timely written notice to the secretary of our
company prior to the meeting at which directors are to be elected, will be
eligible for election as directors. This procedure also requires that, in order
to raise matters at an annual or special meeting, those matters be raised before
the meeting pursuant to the notice of meeting we deliver or by, or at the
direction of, our chairman or by a stockholder who is entitled to vote at the
meeting and who has given timely written notice to the secretary of our company
of his intention to raise those matters at the annual meeting. If our chairman
or other officer presiding at a meeting determines that a person was not
nominated, or other business was not brought before the meeting, in accordance
with the notice procedure, that person will not be eligible for election as a
director, or that business will not be conducted at the meeting.

     Amendment.  Our certificate of incorporation provides that the affirmative
vote of the holders of at least 75% of the voting power of the outstanding
shares entitled to vote, voting together as a single class, is required to amend
provisions of our certificate of incorporation relating to the prohibition of
stockholder action without a meeting, the number, election and term of our
directors and the removal of directors. Our certificate of incorporation further
provides that our by-laws may be amended by our board or by the affirmative vote
of the holders of at least 75% of the outstanding shares entitled to vote,
voting together as a single class.

  Rights Agreement

     On July 23, 2002, our board of directors adopted a preferred share purchase
rights plan. In connection with the rights plan, our board of directors declared
a dividend of one preferred share purchase right for each outstanding share of
our common stock. The rights dividend was paid on August 12, 2002 to the
stockholders of record on that date.

     Purchase Price.  Each right entitles the registered holder to purchase from
us one one-hundredth of a share of our Series A Junior Participating Preferred
Stock, or preferred shares, par value $0.01 per share, at a price of $110 per
one one-hundredth of a preferred share, subject to adjustment.

     Flip-In.  In the event that any person or group of affiliated or associated
persons acquires beneficial ownership of 15% or more of our outstanding common
stock, each holder of a right, other than rights beneficially owned by the
acquiring person (which will thereafter be void), will thereafter have the right
to receive upon exercise that number of shares of our common stock having a
market value of two times the exercise price of the right.

     Flip-Over.  If we are acquired in a merger or other business combination
transaction or 50% or more of our consolidated assets or earning power are sold
after a person or group acquires beneficial ownership of 15% or more of our
outstanding common stock, each holder of a right (other than rights beneficially
owned by the acquiring person, which will be void) will thereafter have the
right to receive that number of shares of common stock of the acquiring company
which at the time of such transaction will have a market value of two times the
exercise price of the right.

of our common stock less the sum of all of our common stock disposed of by the
Lehman parties to non-affiliates after July 24, 2002.

     Distribution Date.  The distribution date is the earlier of

          (1) 10 days following a public announcement that a person or group of
     affiliated or associated persons have acquired beneficial ownership of 15%
     or more of our outstanding common stock; or

          (2) 10 business days (or such later date as may be determined by
     action of our board of directors prior to such time as any person or group
     of affiliated persons acquires beneficial ownership of 15% or more of our
     outstanding common stock) following the commencement of, or announcement of
     an intention to make, a tender offer or exchange offer the consummation of
     which would result in the beneficial ownership by a person or group of 15%
     or more of our outstanding common stock.

     Transfer and Detachment.  Until the distribution date, the rights will be
evidenced either by book entry in our direct registration system or, with
respect to any of our common stock certificates outstanding as of August 12,
2002, by such common stock certificate with a copy of the Summary of Rights
attached thereto. Until the distribution date (or earlier redemption or
expiration of the rights), the rights will be transferred with and only with the
common stock, and transfer of those shares will also constitute transfer of the
rights.

     As soon as practicable following the distribution date, separate
certificates evidencing the rights will be mailed to holders of record of our
common stock as of the close of business on the distribution date and the
separate certificates evidencing the rights alone will thereafter evidence the
rights.

     Exercisability.  The rights are not exercisable until the distribution
date. The rights will expire at the earliest of (1) August 11, 2012, unless that
date is extended, (2) the time at which we redeem the rights, as described
below, or (3) the time at which we exchange the rights, as described below.

     Adjustments.  The purchase price payable, and the number of preferred
shares or other securities or property issuable, upon exercise of the rights are
subject to adjustment from time to time to prevent dilution in the event of
stock dividends, stock splits, reclassifications, or certain distributions with
respect to the preferred shares. The number of outstanding rights and the number
of one one-hundredths of a preferred share issuable upon exercise of each right
are also subject to adjustment if, prior to the distribution date, there is a
stock split of our common stock or a stock dividend on our common stock payable
in common stock or subdivisions, consolidations or combinations of our common
stock. With certain exceptions, no adjustment in the purchase price will be
required until cumulative adjustments require an adjustment of at least 1% in
the purchase price. No fractional preferred shares will be issued (other than
fractions which are integral multiples of one one-hundredth of a preferred
share, which may, at our election, be evidenced by depositary receipts) and, in
lieu thereof, an adjustment in cash will be made based on the market price of
the preferred shares on the last trading day prior to the date of exercise.

     Preferred Shares.  Preferred shares purchasable upon exercise of the rights
will not be redeemable. Each preferred share will be entitled to a minimum
preferential quarterly dividend payment of $1.00 per share but will be entitled
to an aggregate dividend of 100 times the dividend declared per share of common
stock. In the event of liquidation, the holders of the preferred shares will be
entitled to a minimum preferential liquidation payment of $100 per share but
will be entitled to an aggregate payment of 100 times the payment made per share
of common stock. Each preferred share will have 100 votes, voting together with
the common stock. Finally, in the event of any merger, consolidation or other
transaction in which shares of our common stock are exchanged, each preferred
share will be entitled to receive 100 times the amount received per share of
common stock. These rights are protected by customary anti-dilution provisions.
                                        14


     The value of the one one-hundredth interest in a preferred share
purchasable upon exercise of each right should, because of the nature of the
preferred shares' dividend, liquidation and voting rights, approximate the value
of one share of our common stock.

     Exchange.  At any time after any person or group acquiring beneficial
ownership of 15% or more of our outstanding common stock, and prior to the
acquisition by such person or group of beneficial ownership of 50% or more of
our outstanding common stock, our board of directors may exchange the rights
(other than rights owned by the acquiring person, which will have become void),
in whole or in part, at an exchange ratio of one share of our common stock, or
one one-hundredth of a preferred share (subject to adjustment).

     Redemption.  At any time prior to any person or group acquiring beneficial
ownership of 15% or more of our outstanding common stock, our board of directors
may redeem the rights in whole, but not in part, at a price of $0.001 per right.
The redemption of the rights may be made effective at such time on such basis
with such conditions as our board of directors in its sole discretion may
establish. Immediately upon any redemption of the rights, the right to exercise
the rights will terminate and the only right of the holders of rights will be to
receive the redemption price.

     Amendments.  The terms of the rights may be amended by our board of
directors without the consent of the holders of the rights, including an
amendment to lower certain thresholds described above to not less than the
greater of (1) the sum of .001% and the largest percentage of our outstanding
common stock then known to us to be beneficially owned by any person or group of
affiliated or associated persons and (2) 10%, except that from and after such
time as any person or group of affiliated or associated persons acquires
beneficial ownership of 15% or more of our outstanding common stock, no such
amendment may adversely affect the interests of the holders of the rights.

     Rights and Holders.  Until a right is exercised, the holder thereof, as
such, will have no rights as a stockholder of our company, including, without
limitation, the right to vote or to receive dividends.

     Anti-takeover Effects.  The rights have certain anti-takeover effects. The
rights will cause substantial dilution to a person or group that attempts to
acquire us on terms not approved by our board of directors, except pursuant to
any offer conditioned on a substantial number of rights being acquired. The
rights should not interfere with any merger or other business combination
approved by our board of directors since the rights may be redeemed by us at the
redemption price prior to the time that a person or group has acquired
beneficial ownership of 15% or more of our common stock.

                              PLAN OF DISTRIBUTION

     We are registering the shares of our common stock on behalf of the selling
stockholders. The selling stockholders may offer their shares of our common
stock at various times in one or more of the following transactions:

     - to or through underwriting syndicates represented by managing
       underwriters;

     - through one or more underwriters without a syndicate for them to offer
       and sell to the public;

     - through dealers or agents; or

     - to investors directly in negotiated sales or in competitively bid
       transactions.

     The prospectus supplement for the shares of common stock the selling
stockholders sell will describe that offering, including:

     - the name or names of any underwriters;

     - the purchase price and the proceeds to the selling stockholders from that
       sale;

     - any underwriting discounts and other items constituting underwriters'
       compensation; and

     - any discounts or concessions allowed or reallowed or paid to dealers.

UNDERWRITERS

     If underwriters are used in the sale, we and the selling stockholders will
execute an underwriting agreement with those underwriters relating to the shares
of common stock that the selling stockholders will offer. Unless otherwise set
forth in the prospectus supplement, the obligations of the underwriters to
purchase the shares of common stock will be subject to conditions. The
underwriters will be obligated to purchase all of the shares of common stock if
any are purchased.

     The shares of common stock subject to the underwriting agreement will be
acquired by the underwriters for their own account and may be resold by them
from time to time in one or more transactions, including negotiated
transactions, at a fixed public offering price or at varying prices determined
at the time of sale. Underwriters may be deemed to have received compensation
from the selling stockholders in the form of underwriting discounts or
commissions and may also receive commissions from the purchasers of the common
stock for whom they may act as agent. Underwriters may sell the shares of common
stock to or through dealers. These dealers may receive compensation in the form
of discounts, concessions or commissions from the underwriters and/or
commissions from the purchasers for whom they may act as agent. Any discounts or
concessions allowed or reallowed or paid to dealers may be changed from time to
time.

AGENTS

     The selling stockholders may also sell the shares of common stock through
agents designated by the selling stockholders from time to time. The selling
stockholders will name any agent involved in the offer or sale of the common
stock and will list commissions payable by the selling stockholders to these
agents in the prospectus supplement. These agents will be acting on a best
efforts basis to solicit purchases for the period of their appointment, unless
the selling stockholders state otherwise in the prospectus supplement.

DIRECT SALES

     The selling stockholders may sell the shares of common stock directly to
purchasers. In this case, the selling stockholders will not engage underwriters
or agents in the offer and sale of the shares of common stock.

                                        16


RULE 144

     The selling stockholders also may sell all or a portion of their shares in
open market transactions in reliance upon Rule 144 under the Securities Act,
provided they meet the criteria and conform to the requirements of that rule.

INDEMNIFICATION

     The selling stockholders may indemnify underwriters, dealers or agents, or
the controlling persons of any of them, who participate in the distribution of
common stock against certain liabilities, including liabilities under the
Securities Act of 1933 and agree to contribute to payments which these
underwriters, dealers or agents, or the controlling persons of any of them, may
be required to make.

                          VALIDITY OF OUR COMMON STOCK

     The validity of the shares of common stock to be offered in this prospectus
will be passed upon for us by our counsel, Simpson Thacher & Bartlett, New York,
