During the Term of Employment, the Board and the CEO shall review in good faith, at least annually, Executive’s Base Salary in accordance with the Company’s customary procedures and practices regarding the salaries of senior executives and may, if determined by the Board to be appropriate, increase Executive’s Base Salary following such review. “Base Salary” for all purposes herein shall be deemed to be a reference to any such increased amount.

      3.2 Annual Bonus . In addition to his Base Salary, Executive shall, commencing with the 2007 calendar year and continuing for each calendar year thereafter during the Term of Employment, be eligible to receive an annual cash bonus (the “Bonus”) in accordance with a program to be developed by the Board, based on achievement of performance targets established by the Board in consultation with the CEO as soon as practicable at or after the beginning of the calendar year to which the performance targets relate. The target for the 2007 bonus amount shall be determined before or as soon as practicable after the Commencement Date. Executive’s target and maximum annual Bonus percentages are set forth on the signature page hereof. A Bonus award for any calendar year shall be payable to Executive at the time bonuses are paid to other executive officers for such calendar year in accordance with the Company’s policies and practices as set by the Board in consultation with the CEO, but in no event later than March 15 of the calendar year following the later of (a) the calendar year in which the Bonus is earned or (b) the calendar year in which the Bonus is no longer subject to a substantial risk of forfeiture within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and the guidance promulgated and in effect thereunder (“Section 409A”).

Such award shall consist of stock options and restricted stock units, which will be granted on or about November 1, 2007. The stock options will be granted

with an exercise price per share equal to the closing market price of a share of Company common stock on the grant date. The restricted stock units will be granted with a value per unit equal to the closing market price of a share of Company common stock on the grant date.

In the case of termination of Executive’s employment due to Executive’s Disability (as defined in Section 6.4 hereof) or death, any options held by Executive as of such date shall remain exercisable until at least the earlier of (i) the date that is one (1) year after the date of termination of Executive’s employment or (ii) the date on which the option would have expired solely by reason of the passage of time if Executive’s employment had not been terminated, provided that no option shall remain outstanding longer than the maximum time permitted by Section 409A.

     (d) The Long Term Incentive Awards shall be governed by separate grant agreements (together with any other agreement approved by the Board and designated by the Board as an “Ancillary Document” for purposes of this Agreement, the “Ancillary Documents”). To the extent permitted by any applicable law and the rules of any exchange on which the Company’s stock is listed, in the event of any conflict between an Ancillary Document and the terms of this Agreement, the terms of this Agreement shall govern.

     (e) All Long Term Incentive Awards and any other equity-based awards granted to Executive by the Company shall be approved by a committee of the Board comprised of individuals who are both disinterested directors (within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) and independent directors (within the meaning of

applicable stock exchange rules) and shall be exempt from Section 16(b) of the Exchange Act by reason of Rule 16b-3 under the Exchange Act.

      4.2 Employee Benefit Programs, Plans and Practices; Perquisites .

To the extent permitted by applicable law, applicable tax-qualification requirements, and any relevant benefit plan document, Executive’s service with Peabody Energy Corporation and its affiliates shall be taken into account for purposes of determining eligibility, vesting, level of benefits and benefit accruals under the Company’s benefit plans (except to the extent that such service credit would result in a duplication of benefits).

      4.3 Vacation . Executive shall be entitled to the number of business days paid vacation in each calendar year as determined in accordance with the Company’s applicable vacation policies, which shall be taken at such times as are reasonably consistent with Executive’s responsibilities hereunder.

      5.  Expenses . Subject to prevailing Company policy or such guidelines as may be established by the Board, the Company will reimburse Executive for all reasonable expenses incurred by Executive in carrying out his duties on behalf of the Company, provided that such reimbursement is not taxable income to Executive.

      6.1 Termination of Employment for Any Reason . In the event of a termination of Executive’s employment for any reason, the Company shall pay to Executive (a) within five (5) business days following the date of termination of Executive’s employment, a lump sum equal to (i) Executive’s Base Salary earned on or prior to the date of such termination but not yet paid to Executive in accordance with the Company’s customary procedures and practices regarding the salaries of senior executives, (ii) any business expenses incurred by Executive and not yet reimbursed by the Company under Section 5 above, as of the date of such termination, (iii) any vacation time accrued but unused as of the date of such termination, and (iv) any Bonus earned but not yet paid for any calendar year prior to the date of such termination and (b) any benefits accrued and vested under any of the Company’s employee benefit programs, plans and practices on or prior to the date of termination of Executive’s employment (remuneration described in (a) and (b) above are collectively referred to as the “Accrued Obligations” herein) in accordance with the terms of such programs, plans and practices.

(a) The Company or Executive may terminate Executive’s Term of Employment at any time for any reason by providing written notice to the other party at least thirty (30) days (or such other number of days specified in this Agreement) in advance of the date of termination of Executive’s

employment. If Executive terminates his employment for Good Reason, such notice shall describe the conduct Executive believes to constitute Good Reason and the Company shall have the opportunity to cure the Good Reason within thirty (30) days of receiving such notice. If the Company cures the conduct that is the basis for the potential termination for Good Reason within such thirty (30) day period, Executive’s notice of termination shall be deemed withdrawn.

If Executive’s employment is terminated (i) by the Company other than for Cause (as defined in Section 6.3(b) hereof), Disability (as defined in Section 6.4 hereof) or death or (ii) by Executive for Good Reason (as defined in Section 6.2(b) hereof), and such termination constitutes a Separation from Service (as hereinafter defined), the Company, as severance, shall pay to Executive an amount (the “Severance Payment”) equal to the total of:

     (C) an additional amount equal to six percent (6%) of Executive’s Base Salary.

The Company shall pay to Executive (I) one-half (1/2) of such Severance Payment in a lump sum payment on the six (6) month anniversary of Executive’s Separation from Service and (II) the remaining one-half (1/2) of the Severance Payment in six (6) equal monthly payments beginning on the seven (7) month anniversary of Executive’s Separation from Service.

(1) The Company shall pay to Executive a prorated bonus (the “Prorated Bonus”) for the calendar year of termination of Executive’s employment, calculated as the Bonus Executive would have received in such year based on actual performance multiplied by a fraction, the numerator of which is the number of business days during the calendar year of termination that Executive was

employed and the denominator of which is the total number of business days during the calendar year of termination. The Prorated Bonus shall be payable when annual bonuses are paid to other senior executives of the Company, but in no event later than March 15 of the calendar year following the later of (a) the calendar year in which the Bonus is earned or (b) the calendar year in which the Bonus is no longer subject to a substantial risk of forfeiture within the meaning of Section 409A.

Notwithstanding the foregoing, if Executive breaches any provision of Section 13 hereof, the remaining balances of the Severance Payment, the Prorated Bonus, and any Continuation Benefits shall be forfeited.
