On December 21, 2012, Resolute Natural Resources Southwest, LLC, a Delaware limited liability company ("Resolute Southwest"), and a wholly-owned subsidiary of Resolute Energy Corporation ("Resolute" or the "Company"), acquired certain Permian Basin oil and gas properties located primarily in Howard County, Texas, and Lea County, New Mexico (the "Celero Properties"), from Celero Energy II, LP and an affiliate ("Celero"), for a purchase price of approximately $115 million (the "Celero Acquisition"). Natural Gas Partners, an affiliate of the Company, is also an affiliate of Celero. See the Current Reports on Form 8-K filed on December 5, 2012 and December 26, 2012, respectively, for a detailed explanation of the acquisition of the Celero Properties.

On December 28, 2012, Resolute Southwest acquired an undivided 32.35% interest in certain Permian Basin oil and gas properties near Midland, Texas (the "RSP Properties"), pursuant to the terms of a Purchase, Sale and Option Agreement with RSP Permian, L.L.C., a Delaware limited liability company ("RSP"), Wallace Family Partnership, LP, a Texas limited partnership, Ted Collins, Jr. and certain additional "tag-along" sellers (collectively "RSP Sellers"). Natural Gas Partners, an affiliate of the Company, is also an affiliate of RSP. The purchase price for all acquired interests was approximately $133 million (the "RSP Acquisition"). The $133 million purchase price paid to the RSP Sellers included a non-refundable $6 million paid in exchange for the option to acquire the remaining undivided 67.65% interest in the RSP Properties for a purchase price of approximately $261 million at any time through March 22, 2013, although the option fee would be applied against that purchase price. Resolute has given notice of its intent to exercise this option, but has not completed financing for the acquisition, and is not obligated to close. See the Current Report on Form 8-K filed on December 31, 2012 for a detailed explanation of the acquisition of the RSP Properties and the Form 8-K filed on March 4, 2013 regarding exercise of the option.
