On April 19, 2010, Massey Energy Company (the “Company”) completed its previously-announced acquisition (the “Acquisition”) of Cumberland Resources Corporation and certain affiliated companies (“Cumberland”). The Company’s press release announcing the closing of the Acquisition is attached hereto as Exhibit 99.1 and is incorporated by reference herein.

The Company completed the Acquisition pursuant to a Purchase, Sale and Merger Agreement (the “Purchase Agreement”), dated as of March 16, 2010, among the Company, Cumberland Resources Corporation, Powell River Resources Corporation and the Sellers named therein. The purchase price paid by the Company at closing consisted of $640 million in cash, subject to working capital adjustments, and 6,519,034 shares of Company common stock. The number of shares issued was calculated by dividing $320 million by the average closing price of the Company’s common stock for the 20 trading days ending on April 16, 2010. Pursuant to the Purchase Agreement, an indirect, wholly-owned subsidiary of the Company purchased the membership interests of certain of the Cumberland limited liability company affiliates from the Sellers and each of Cumberland Resources Corporation and Powell River Resources Corporation were merged into wholly-owned subsidiaries of the Company.

In connection with the closing of the Acquisition, the Company entered into a registration rights agreement (the “Registration Rights Agreement”) with each of the Holders (as defined in the Registration Rights Agreement) who received Company common stock in the Acquisition. Pursuant to the Registration Rights Agreement, the Company has agreed to file a prospectus supplement under an existing shelf registration statement permitting the Holders to sell the shares of Company common stock such Holders received in the Acquisition. In addition, pursuant to the terms of the Registration Rights Agreement, the Company has granted such Holders a one time right to require the Company to register their shares of Company common stock on a registration statement on Form S-3, provided that the shares of Company common stock requested to be included in such registration have a fair market value of at least $50 million. The Holders who received shares of Company common stock in the Acquisition are not subject to any lock-up period with respect to the sale of such shares.

A copy of the Registration Rights Agreement is attached hereto as Exhibit 4.1 and is incorporated by reference herein. The description of the Registration Rights Agreement set forth in this Item 1.01 is not complete and is qualified in its entirety by reference to the full text of the Registration Rights Agreement set forth on Exhibit 4.1.

The information set forth in Item 1.01 of this Current Report on Form 8-K is incorporated herein by reference into this Item 2.01.

In connection with the Acquisition of Cumberland, the Company previously filed audited combined balance sheets as of December 31, 2009 and 2008 and the related combined statements of income, stockholder’s equity and members’ capital and comprehensive income, and cash flows for each of the years in the three-year period ended December 31, 2009 of Cumberland Resources Corporation and Resource Development LLC and their affiliated companies (the “Cumberland Resource Group”), which are included herein as Exhibit 99.2 and incorporated by reference herein.

In connection with the Acquisition of Cumberland, the Company previously filed the unaudited pro forma condensed consolidated balance sheet as of December 31, 2009 and the related unaudited pro forma condensed consolidated statement of income for the year ended December 31, 2009, which are included herein as Exhibit 99.3 and incorporated by reference herein.
