Dear Rick:

This letter agreement will confirm that in recognition of your dedicated and
loyal service to Peabody Energy Corporation (the "Company"), and in order to
induce you to continue to serve the Company in your current position, the
Company has decided that it is appropriate to give you the additional incentive
described below:

1.       In addition to any compensation to which you may be entitled under the
         Employment Agreement dated May 19, 1998 and amended May 10, 2001,
         between you and the Company (the "Employment Agreement"), you will be
         entitled to receive an additional bonus (the "Retention Bonus") equal
         to one (1) times your then current Base Salary (as that term is defined
         in the Employment Agreement) if you remain in the Company's employ
         until the date two (2) years after the date hereof and meet applicable
         performance goals, as determined by the CEO (as that term is defined in
         the Employment Agreement), during such two-year period. Subject to
         Paragraphs 2 and 3 below, if your employment with the Company ends for
         any reason at any time before the expiration of the two-year period
         mentioned in the immediately preceding sentence, or if you fail to meet
         applicable performance goals, as determined by the CEO during such
         two-year period, you will not be entitled to the Retention Bonus
         hereunder.

2.       Notwithstanding anything to the contrary in Paragraph 1 above, if your
         employment with the Company is terminated before the expiration of the
         two-year period mentioned in Paragraph 1 above, either by you for Good
         Reason (as that term is defined in the Employment Agreement) or by the
         Company without Cause (as that term is defined in the Employment
         Agreement), you will be entitled to receive the Retention Bonus
         hereunder as of the date of such termination.

3.       Notwithstanding anything to the contrary in Paragraph 1 above, if your
         employment with the Company is terminated before the expiration of the
         two-year period mentioned in Paragraph 1 above as a result of your
         death or Disability (as that term is defined in the Employment
         Agreement), you (or your beneficiary)

         will be entitled to receive, as of the date of such termination, an
         amount equal to the Retention Bonus multiplied by a fraction the
         numerator of which is the number of full calendar months that will have
         elapsed during the period beginning on the date hereof and ending on
         the date of termination of your employment with the Company, and the
         denominator of which is 24.

4.       If the conditions set forth in Paragraph 1, 2 or 3 above are met, the
         Retention Bonus (or the prorated amount described in Paragraph 3) will
         be paid by the Company as soon as administratively feasible after the
         date on which such conditions are met. Any amount payable hereunder
         will be subject to customary withholding taxes and such other
         employment taxes as are required under federal law or the law of any
         state or other governmental body to be collected with respect to
         compensation paid by an employer to an employee.

5.       Other than as explicitly set forth herein, your employment with the
         Company otherwise continues to be governed by the terms and conditions
         of the Employment Agreement.

Please confirm your agreement with the foregoing by signing and dating the
enclosed duplicate copy of this letter agreement and returning that copy to me
by September 5, 2003.

                                            Very truly yours,

Dear Rick:

As you know, effective as of October 1, 2003, you will cease to report directly
to the Chief Executive Officer of Peabody Energy Corporation (the "Company") and
will instead report to the Company's Chief Operating Officer. This letter
agreement will confirm that the Company desires to demonstrate its high regard
for you and has decided that it is appropriate to give you the additional
incentives described below (i) to induce you to continue to serve the Company in
your current position and (ii) to encourage your highest cooperation and
goodwill as the change in your reporting relationships described above occurs.

1.       Effective September 1, 2003, notwithstanding anything to the contrary
         in the Employment Agreement dated May 19, 1998, as amended as of May
         10, 2001, between you and the Company (the "Employment Agreement"), the
         Company will pay you an annual Base Salary (as that term is defined in
         the Employment Agreement) of $500,000 payable in accordance with the
         ordinary payroll practices of the Company. Your Base Salary otherwise
         continues to be governed by the terms and conditions of the Employment
         Agreement.

2.       In addition to any compensation to which you may be entitled under the
         Employment Agreement, you will be entitled to receive, as of September
         1, 2005, an additional bonus described below (the "Retention Bonus") if
         you remain in the Company's employ through August 31, 2005, and meet
         applicable performance goals, as determined by the CEO (as that term is
         defined in the Employment Agreement), during such period. The Retention
         Bonus will be equal to the lesser of:

         (i)      The sum of (a) your then current annual Base Salary and (b)
                  the product of your then current annual Base Salary multiplied
                  by the greater of the percentage rates applicable to your
                  annual incentives for the 2003 and 2004 fiscal years, based on
                  actual performances for each such fiscal year; and

         (ii)     $1,200,000 minus the sum of:

                  (a)      the total amount of Base Salary increase paid to you
                           under this letter agreement for the period beginning
                           on September 1, 2003, and ending on August 31, 2005;

                  (b)      the total amount of the incremental annual incentive
                           payments actually received by you with respect to the
                           2003 and 2004 fiscal years, as a result of the Base
                           Salary increase under this letter agreement; and

                  (c)      $50,000 (which corresponds to the total amount of
                           additional long-term incentive payments to be made to
                           you for the period beginning on September 1, 2003,
                           and ending on August 31, 2005, as a result of the
                           Base Salary increase under this letter agreement).

3.       Notwithstanding anything to the contrary in Paragraph 2 above, if your
         employment with the Company is terminated before September 1, 2005,
         either by you for Good Reason (as that term is defined in the
         Employment Agreement, but excluding the change in your reporting
         relationships described above) or by the Company without Cause (as that
         term is defined in the Employment Agreement), you will be entitled to
         receive the Retention Bonus hereunder as of the date of such
         termination; provided that such Retention Bonus will be equal to
         $1,200,000 minus the sum of:

         (i)      the total amount of Base Salary increase paid to you under
                  this letter agreement for the period beginning on September 1,
                  2003, and ending on the date of termination of your employment
                  with the Company;

         (ii)     the total amount of the incremental annual incentive payments
                  actually received by you with respect to such portion of the
                  2003 and 2004 fiscal years as will end on the date of
                  termination of your employment with the Company, as a result
                  of the Base Salary increase under this letter agreement; and

         (iii)    $25,000 if your employment with the Company is terminated on
                  or after January 1, 2004, but before January 1, 2005; or
                  $50,000 if your employment with the Company is terminated on
                  or after January 1, 2005.

4.       Notwithstanding anything to the contrary in Paragraph 2 above, if your
         employment with the Company is terminated before September 1, 2005, as
         a result of your death or Disability (as that term is defined in the
         Employment Agreement), you (or your beneficiary) will be entitled to
         receive, as of the date of such termination, an amount equal to the
         Retention Bonus, as calculated under Paragraph 3 above, multiplied by a
         fraction the numerator of which is the number

                                       2

<PAGE>

         of calendar days that will have elapsed during the period beginning
         September 1, 2003, and ending on the date of termination of your
         employment with the Company, and the denominator of which is 731.

5.       If your employment with the Company ends at any time before September
         1, 2005, for any reason other than the reasons set forth in Paragraphs
         3 and 4 above (including, but not limited to, a termination of your
         employment with the Company by you without Good Reason (as that term is
         defined above) or by the Company for Cause (as that term is defined in
         the Employment Agreement)), or if you fail to meet applicable
         performance goals, as determined by the CEO during such period, you
         will not be entitled to the Retention Bonus hereunder.

6.       If the conditions set forth in Paragraph 2, 3 or 4 above are met, the
         Retention Bonus (or the prorated amount described in Paragraph 4) will
         be paid by the Company as soon as administratively feasible after the
         date on which such conditions are met. Any amount payable hereunder
         will be subject to customary withholding taxes and such other
         employment taxes as are required under federal law or the law of any
         state or other governmental body to be collected with respect to
         compensation paid by an employer to an employee.

7.       Other than as explicitly set forth herein, your employment with the
         Company otherwise continues to be governed by the terms and conditions
         of the Employment Agreement.
