Hicks Acquisition Company I Enters into Agreement with Victory Park

DALLAS – (BUSINESS WIRE) – Hicks Acquisition Company I, Inc. (the “Company”), a special purpose acquisition company founded and headed by Thomas O. Hicks, announced today that it intends to convene and then adjourn, without conducting any business, its special meeting of warrantholders and special meeting of stockholders until Friday, September 25, 2009, at 8:30 a.m. Central Daylight time and 9:00 a.m. Central Daylight time, respectively, in order to give the Company warrantholders and stockholders additional time to consider supplemental proxy materials and to vote on the proposals to be considered at the special meetings. Both special meetings will still be held at the offices of Akin Gump Strauss Hauer & Feld LLP, 1700 Pacific Avenue, 39th Floor, Dallas, Texas 75201.

Limited Waiver of Closing Condition

The Company also announced that Resolute Energy Corporation (“Resolute”) and its affiliates that are party to that certain Purchase and IPO Reorganization Agreement, dated as of August 2, 2009, by and among the Company, Resolute, Resolute Holdings Sub, LLC, Resolute Subsidiary Corporation, a wholly-owned subsidiary of Resolute, Resolute Aneth, LLC, Resolute Holdings, LLC, and HH-HACI, L.P., as amended by that certain Letter Agreement dated as of September 9, 2009 (the “Acquisition Agreement”); pursuant to which the Company’s stockholders will acquire a majority of the outstanding shares of capital stock of Resolute (collectively, the “Acquisition”), have granted a limited waiver to the closing condition to their obligation to consummate the Acquisition stated in Section 7.3(e) of the Acquisition Agreement, but only to the extent that the Acquisition Consideration is not less than $240,000,000.00. To the extent the amount actually paid by the Company to Resolute is less than the originally contemplated $275 million, Resolute will still fully repay its Second Lien Credit Facility however, Resolute’s repayment of the part of its outstanding indebtedness on its First Lien Credit Facility will be reduced, resulting in greater outstanding indebtedness immediately following the consummation of Acquisition.

Stock Purchase Agreements

The Company also announced that it has entered into agreements in privately negotiated transactions (the “Purchase Agreements”) to purchase an aggregate of 7,503,133 shares of the Company’s common stock issued in its initial public offering (“Public Shares”) at prices ranging from $9.76 to $9.78 per share from stockholders who otherwise intended to vote against the Acquisition. It is possible that additional Purchase Agreements may be entered into by the Company. The purchases of Public Shares pursuant to the Purchase Agreements will take place concurrently with or following the closing of the Acquisition and the purchases will be paid for with funds that will be released from the Company’s trust account upon consummation of the Acquisition. Any additional purchases entered into by the Company may be entered into at a purchase price slightly higher than the per share conversion price at the time of the Acquisition.

Pursuant to the Purchase Agreements, the sellers have agreed to have their Public Shares voted in favor of each of the stockholder proposals set forth in the Company’s definitive proxy statement/prospectus, dated September 14, 2009, filed with the Securities and Exchange Commission on September 15, 2009, and as supplemented on September 22, 2009 (the “Definitive Proxy Statement/Prospectus”).

Such purchases, if made, would increase the likelihood that holders of a majority of shares of the Company’s common stock will vote in favor of the Acquisition and that holders of less than 30% of Public Shares vote against the Acquisition and seek conversion of their Public Shares into cash in accordance with the Company’s charter.

Victory Park Agreement

The Company also announced that it entered into an agreement (the “Victory Agreement”) with Victory Park Capital Advisors, LLC (“Victory Park”), pursuant to which funds managed by Victory Park or other purchasers acceptable to Victory Park and the Company may purchase, if directed by the Company, up to an aggregate of 4.5 million shares of the Company’s common stock from third parties prior to the Company’s special meeting of stockholders. Victory Park is not an affiliate of any of the Company, its officers and directors and/or their respective affiliates, or Resolute, or its officers and directors and/or their respective affiliates. It is anticipated that Victory Park will effect purchases of Public Shares through independent, privately negotiated transactions with third parties who are institutions or other sophisticated investors that have voted against or indicated an intention to vote against the Acquisition and exercise their conversion rights.

Pursuant to the Victory Agreement, the Company will pay Victory Park a fee of 1.0% of the value of all shares of the Company’s common stock purchased by Victory Park from third parties. All shares purchased as a result of this Victory Agreement will vote in favor of each of the stockholder proposals to be presented at the Company’s special meeting of stockholders, which proposals are set forth in the Definitive Proxy Statement/Prospectus. In connection with each purchase of Public Shares by Victory Park pursuant to the Victory Agreement, Victory Park and the Company will enter into a stock purchase agreement (each, a “Victory Purchase Agreement”), pursuant to which the Company will agree to purchase such Public Shares from Victory Park at a price equal to the aggregate purchase price paid by Victory Park for such shares plus the 1.0% fee described above. No funds other than those payable to Victory Park may be released from the trust account containing the net proceeds of the Company’s initial public offering following the consummation of the Acquisition until the Company has paid Victory Park pursuant to the Victory Purchase Agreements in full except to converting stockholders. Such purchases, if made, would increase the likelihood that holders of a majority of shares of the Company’s common stock will vote in favor of the Acquisition and that holders of less than 30% of Public Shares vote against the Acquisition and seek conversion of their Public Shares into cash in accordance with the Company’s charter.
