Explanation of Responses:

1. Includes 28,465 shares of Restricted Stock received by the reporting person under the Patriot Coal Corporation 2007 Long-Term Incentive Plan (the "LTIP") with the following grant and vesting dates: 11/1/07 - 2,883 shares currently outstanding (4,268 shares vested on 11/1/10, of which 1,385 shares were sold to satisfy tax obligations). 3/12/08 - 1,406 shares currently outstanding (1,092 shares vested on 3/12/09 and 1,092 shares vested on 3/12/10, of which a total of 778 shares were sold to satisfy tax obligations). 1/30/09 - 13,014 shares currently outstanding, all of which will vest on 1/2/12. 1/4/10 - 5,581 shares currently outstanding (2,120 shares vested on 1/4/11, of which 777 shares were sold to satisfy tax obligations, 2,119 shares will vest on 1/4/12, and 2,119 shares will vest on 1/4/13). 1/3/11 - 5,581 shares currently outstanding (1,861 shares will vest on 1/3/12, 1,860 shares will vest on 1/3/13 and 1,860 shares will vest on 1/3/14).

2. Also includes 3,997 shares acquired under the Patriot Coal Corporation Employee Stock Purchase Plan, 2,519 shares of which are no longer restricted.

3. On November 1, 2007 the reporting person received an award of restricted stock units (the "RSUs") under the LTIP. 4,268 RSUs will vest over time, and will be 50% vested on the fifth anniversary of the grant date, 75% vested on the sixth anniversary and 100% vested on the seventh anniversary, or earlier if the reporting person terminates employment with the Company because of death or disability, or if a change in control occurs; and 6,402 RSUs will vest based upon the Company's financial performance, and will vest according to a formula described in the award agreement, the results of which are calculated as of December 31 following the fifth, sixth and seventh anniversaries of the grant date. All unvested RSUs will be forfeited if the reporting person terminates employment with the Company for any reason other than death or disability (except for performance-based RSUs, which will be forfeited in the event of any termination of employment).

4. On November 1, 2007 the reporting person received an award of non-qualified stock options under the LTIP. The stock options will be 50% exercisable on the fifth anniversary date of the grant, 75% exercisable on the sixth anniversary and 100% exercisable on the seventh anniversary, or earlier if the reporting person terminates employment with Patriot because of death or disability, or if a change in control occurs. Any part of the stock options that are not exercisable will be terminated if a grantee terminates employment with Patriot for any reason other than death or disability prior to the time such stock options have become vested and exercisable. No stock options can be exercised more than ten years after the date of grant, but the ability to exercise the stock options may terminate sooner upon the occurrence of certain events.
