(“ Diamondback ”), filed with the U.S. Securities and Exchange Commission on October 25, 2018 (the “ Proxy Statement ”), to (1) approve the Agreement and Plan of Merger, dated as August 14, 2018 (the “ Merger Agreement ”), by and among Diamondback, Sidewinder Merger Sub Inc., a wholly owned subsidiary of Diamondback (“ Merger Sub ”), and Energen (the “ Merger Proposal ”), pursuant to which Merger Sub will merge with and into Energen (the “ Merger ”) and (2) approve, by a non-binding advisory vote, certain compensation that may be paid or become payable to Energen’s named executive officers that is based on or otherwise relates to the Merger contemplated by the Merger Agreement (the “ Non-Binding Compensation Advisory Proposal ”).
