Delaware Basin Acquisition Purchase and Sale Agreement

On October 4, 2016, Resolute Energy Corporation (the “Company”) and Resolute Natural Resources Southwest, LLC, a wholly-owned subsidiary of the Company (“Buyer”), entered into a Purchase and Sale Agreement (the “Firewheel Purchase Agreement”) with Firewheel Energy, LLC (“Seller”) pursuant to which Buyer agreed to acquire certain oil and gas interests in the Delaware Basin in Reeves County, Texas (the “Firewheel Properties”), for an aggregate consideration to Seller of $135 million, consisting of $90 million in cash and $45 million in shares of common stock of the Company, par value $0.0001 per share (“Common Stock”), priced based on a 10% discount to the volume weighted average price during the 15 trading days ending on October 4, 2016, subject to certain adjustments. Based on such formula, it is expected that 2,114,523 shares of Common Stock will be issued to Seller upon the closing of the purchase of the Firewheel Properties (the “Delaware Basin Acquisition”). The closing of the Delaware Basin Acquisition (the “Closing”) is expected to occur on October 7, 2016, effective as of September 1, 2016.

In connection with the Firewheel Purchase Agreement, the Company entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with Seller, dated October 4, 2016, which will become effective as of the Closing and provide the holder(s) of the shares of Common Stock issued to Seller pursuant to the Firewheel Purchase Agreement with certain rights relating to the registration of such shares of Common Stock under the Securities Act of 1933, as amended (the “Securities Act”). The Registration Rights Agreement requires that the Company file a registration statement with the Securities and Exchange Commission to permit the public resale of such shares of Common Stock no later than twenty days after the Closing and use its reasonable best efforts to cause such registration statement to become effective no later than one hundred twenty days after the Closing, subject to extension under certain circumstances.

Each of the Firewheel Purchase Agreement and the Registration Rights Agreement contains various representations, warranties, covenants and indemnification obligations of the Company and Seller, and in the case of the Firewheel Purchase Agreement, of Buyer, that are customary in transactions of this type.

Preferred Stock Purchase Agreement

On October 4, 2016, the Company entered into a Purchase Agreement (the “Preferred Stock Purchase Agreement”) with BMO Capital Markets Corp. (“Initial Purchaser”), pursuant to which the Company agreed to issue and sell to Initial Purchaser 55,000 shares (the “Firm Securities”) of the Company’s 8⅛% Series B Cumulative Perpetual Convertible Preferred Stock, par value $0.0001 per share (the “Convertible Preferred Stock”). The Preferred Stock Purchase Agreement also provides Initial Purchaser an option to purchase up to 7,500 additional shares (together with the Firm Securities, collectively, the “Securities”) of the Convertible Preferred Stock within 30 days of the date of the Preferred Stock Purchase Agreement.

The offering of the Securities has been and will be made only to persons reasonably believed to be qualified institutional buyers in accordance with Rule 144A under the Securities Act. The Securities were not registered under the Securities Act or the securities laws of any other jurisdiction. The closing and settlement of the sale of the Firm Securities is expected to occur on October 7, 2016.
