Item 5.05 Amendments to the Registrant's Code of Ethics, or Waiver of a Provision of the Code of Ethics.

(a) On April 16, 2009, the Board of Directors of Peabody Energy Corporation ("Peabody") adopted amendments to Peabody’s Code of Business Conduct and Ethics (the "Code of Ethics") which had previously been adopted on April 24, 2008. The Code of Ethics, which is applicable to all directors, officers and salaried employees of Peabody, its subsidiaries and affiliates, was amended to clarify and expand Peabody’s policies with respect to: (i) the retention of records and other communications; (ii) Equal Opportunity and Sexual or Other Illegal Harassment; and (iii) the use of Peabody’s computers, electronic communications and network security. The Code of Ethics was amended to reflect a "plain English" style to make it easier to read and understand. In addition, an introductory letter from Gregory H. Boyce, Peabody’s Chairman and Chief Executive Officer, was included.

The above descriptions of the amendments to the Code of Ethics are qualified in their entirety by reference to the amended Code of Ethics, which is attached as Exhibit 99.1 hereto, and incorporated herein by reference.
