This filing relates to a planned merger (the "Merger") between Alpha Natural Resources, Inc. ("Alpha") and Massey Energy Company ("Massey") pursuant to the terms of an Agreement and Plan of Merger, dated as of January 28, 2011 (the "Merger Agreement"), by and among Alpha, Mountain Merger Sub, Inc. and Massey. The Merger Agreement is on file with the Securities and Exchange Commission as an exhibit to the Current Report on Form 8-K filed by Alpha on January 31, 2011, and is incorporated by reference into this filing.

The following is an internal communication to the employees of Alpha from Alpha's Chief Executive Officer, Kevin Crutchfield, and President, Kurt Kost, dated February 14, 2011.

To:                      Entire Organization

From:                 Kevin Crutchfield and Kurt Kost

Subject:             Integration teams start their work

Date:                   February 14, 2011

Our excitement for the combined future of Alpha Natural Resources and Massey Energy continues to build as we mark an important first step. Last Thursday, teams from Alpha met with their counterparts at Massey at their offices in Julian, W. Va., to begin planning the process of bringing our two businesses together at closing.

This marks the first step of a well thought-out and deliberate approach to integration planning we’re calling “integration set-up.” For about the next four weeks, Alpha functional teams will engage in an open-minded, respectful and honest dialogue with Massey’s leadership to foster a better understanding of how each company works. The information gathered in this dialogue will help define both our integration strategy and an operating model for our combined operations.

After the four-week set-up process concludes, we will transition into a phase called “detailed planning and pre-close implementation,” where we jointly develop and finalize the integration plans for all functions and for the operations so we can hit the ground running on day one (the day the deal closes). We will also define how Alpha’s Running Right process can be optimally deployed.

Our ultimate goal: to run as smoothly as possible, as one organization, upon closing.

Similar to our merger with Foundation Coal, the integration structure spells out distinct roles and responsibilities. An Integration Management Office (IMO)—represented by Alpha/Massey leadership and Deloitte support—will monitor day-to-day projects. The functional “set-up” teams are responsible for the work, making decisions, and execution of integration activities for their functional areas. (See the graphic below outlining the integration process.)

Our transaction is expected to close in mid-2011, assuming regulatory approvals and shareholder votes are obtained in a timely manner.  Between now and close, even though we’ll be in dialogue and making plans for the integration, we must stay focused on conducting “business as usual” as two separate companies, staying safe, and ensuring minimal business disruptions. We understand that there are a lot of unanswered questions because we are just starting to work our way through the integration process. But our promise to you is to communicate important decisions and developments as quickly as we can.

Thanks for making this historic event possible for Alpha and Massey. Together we will become a true industry leader, and lay the foundation for continued growth and success in the future.

Sincerely,

 /s/ Kevin Crutchfield                               /s/ Kurt Kost
