STOCK PURCHASE AGREEMENT

STOCK PURCHASE AGREEMENT (this “Agreement”) made as of this 22nd day of September, 2009 between Hicks Acquisition Company I, Inc., a Delaware corporation (“Buyer” or “HACI”) and the signatory on the execution page hereof (“Seller”).

WHEREAS, Buyer was organized for the purpose of acquiring, through a merger, capital stock exchange, asset acquisition or other similar business combination, an operating business (“Business Combination”); and

WHEREAS, Buyer consummated an initial public offering in October, 2007 (“IPO”) in connection with which it raised net proceeds of approximately $529.1 million, a significant portion of which was placed in a trust account pending the consummation of a Business Combination, or the dissolution and liquidation of Buyer in the event it is unable to consummate a Business Combination on or prior to September 28, 2009 (or October 5, 2009 in the event that the Acquisition is approved by Buyer stockholders); and

WHEREAS, Buyer has entered into that certain Purchase and IPO Reorganization Agreement dated as of August 2, 2009, by and among HACI, Resolute Energy Corporation, a Delaware corporation (the “REC”), Resolute Subsidiary Corporation, a Delaware corporation, Resolute Aneth, LLC, a Delaware limited liability company, Resolute Holdings, LLC, a Delaware limited liability company, Resolute Holdings Sub, LLC, a Delaware limited liability company (“Holdings Sub”), and HH-HACI, L.P., a Delaware limited partnership (collectively, the “Acquisition”), pursuant to which, through a series of transactions, HACI stockholders will acquire a majority of the outstanding common stock of REC, par value $0.0001 per share, (the “REC Common Stock”), and REC will acquire HACI and the business and operations of Holdings Sub; and

WHEREAS, the approval of the Acquisition is contingent upon, among other things, the affirmative vote of holders of a majority of the outstanding common shares of HACI at the special meeting called to approve the Acquisition; and

WHEREAS, pursuant to certain provisions in Buyer’s certificate of incorporation, a holder of shares of Buyer’s common stock issued in the IPO may, if it votes against the Acquisition, demand that Buyer convert such common shares into cash (“Conversion Rights”); and

WHEREAS, the Acquisition cannot be consummated if holders of 30% or more of HACI common stock issued in the IPO exercise their Conversion Rights; and

WHEREAS, Seller has agreed to sell to Buyer and Buyer has agreed to purchase from Seller the common shares set forth on the execution page of this Agreement (“Shares”) for the purchase price per share set forth therein (“Purchase Price Per Share”) and for the aggregate purchase price set forth therein (“Aggregate Purchase Price”).

NOW, THEREFORE, in consideration of the mutual covenants hereinafter set forth and other good and valuable consideration, the sufficiency of which is hereby acknowledged, the parties hereby agree as follows:

1. Purchase. Subject to Section 7, Seller hereby sells to Buyer and Buyer hereby purchases from Seller at the Closing (as defined in Section 4(c)) the Shares at the Purchase Price Per Share, for the Aggregate Purchase Price.

2. Agreement not to Convert; Appointment of Proxy and Attorney-in-Fact. In further consideration of the Aggregate Purchase Price, Seller hereby agrees it has not and will not exercise its Conversion Rights or, if it has already exercised its Conversion Rights, it hereby withdraws and revokes such exercise and will execute all necessary documents and take all actions required in furtherance of such revocation. Seller acknowledges that the record date to vote on the proposals set forth in the proxy statement/prospectus (the “Proxy Statement”) filed by Buyer with the U.S. Securities Exchange Commission (the “SEC”) has passed. Accordingly, solely with respect to the vote for the Acquisition and the other proposals set forth in the Proxy Statement, Seller hereby agrees to upon request of Buyer vote in favor of the Acquisition and such other proposals and appoints Joseph B. Armes and Robert M. Swartz and each of them each with full power of substitution, as his proxy and attorney-in-fact, to the full extent of Seller’s rights with respect to the Shares (and any and all other shares or securities or rights issued or issuable in respect thereof) to vote in such manner as each such person or his substitute shall in his sole discretion deem proper, and to otherwise act (including without limitation acting by written consent) with respect to all the Shares at any meeting of stockholders (whether annual or special and whether or not an adjourned meeting) of Buyer held on or prior to September 28, 2009. This proxy is coupled with an interest and is irrevocable. Execution by Seller of this Agreement shall revoke, without further action, all prior proxies granted by Seller at any time with respect to the Shares (and such other shares or other securities) and no subsequent proxies will be given by Seller (and if given will be deemed not to be effective). This Section 2 shall be governed by the laws of the State of Delaware.

3. No Right to Additional Shares. HACI’s stockholders of record are entitled to receive one share of REC Common Stock for each share of HACI common stock owned immediately prior to the consummation of the Acquisition (the “Exchange”). Although Seller will be a stockholder of record immediately prior to the Acquisition, Seller hereby acknowledges that Seller irrevocably waives any right, title or interest it may have in receiving any such REC Common Stock distributed pursuant to the Exchange. Seller hereby acknowledges that by virtue of the sale hereunder, Seller will not become a stockholder of REC, and the Shares shall automatically be cancelled and shall cease to exist and shall represent only the right to receive the Aggregate Purchase Price there for in accordance with the terms of this Agreement. Additionally, each of Buyer and Seller hereby agree and acknowledge that this provision is material to this Agreement and a significant consideration in Buyer’s willingness to enter into this Agreement.

4. Closing Matters.

(a) Within one business day of the date of this Agreement, (i) Seller shall provide Buyer with a true and correct copy of the voting instruction form with respect to the Shares held by Seller indicating the financial institution through which such shares are held and the control number provided by Broadridge Financial Solutions (or other similar service provider) regarding the voting of the Shares or written confirmation of such information as would appear on the voting instruction form; and (ii) Buyer shall send the notice attached as Annex 1 hereto to HACI’s transfer agent.

(b) Prior to the Closing, Seller shall deliver or cause to be delivered to Buyer appropriate instructions for book entry transfers of ownership of the Shares from Seller to Buyer.

(c) The closing of the purchase and sale of the Shares (“Closing”) will occur on the date on which Buyer’s trust account is liquidated after the Acquisition is consummated (the “Closing Date”). At the Closing, Buyer shall pay Seller the Aggregate Purchase Price by wire transfer from HACI’s trust account of immediately available funds to an account specified by Seller and Seller against delivery of the Shares shall deliver the Shares to Buyer electronically using the Depository Trust Company’s DWAC (Deposit/Withdrawal at Custodian) System to an account specified by Buyer. It shall be a condition to the obligation of Buyer on the one hand and Seller on the other hand, to consummate the

This Agreement or any counterpart may be executed via facsimile transmission, and any such executed facsimile copy shall be treated as an original.

11. Governing Law. This Agreement shall for all purposes be deemed to be made under and shall be construed in accordance with the laws of the State of New York (except to the extent otherwise provided in Section 2). Each of the parties hereby agrees that any action, proceeding or claim against it arising out of or relating in any way to this Agreement shall be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York, and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive. Each of the parties hereby waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum.

12. Remedies. Each of the parties hereto acknowledges and agrees that, in the event of any breach of any covenant or agreement contained in this Agreement by the other party, money damages may be inadequate with respect to any such breach and the non-breaching party may have no adequate remedy at law. It is accordingly agreed that each of the parties hereto shall be entitled, in addition to any other remedy to which they may be entitled at law or in equity, to seek injunctive relief and/or to compel specific performance to prevent breaches by the other party hereto of any covenant or agreement of such other party contained in this Agreement.

13. Binding Effect; Assignment. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective legal representatives, successors and permitted assigns. This Agreement shall not be assigned by either party without the prior written consent of the other party hereto.

14. Headings. The descriptive headings of the Sections hereof are inserted for convenience only and do not constitute a part of this Agreement.

15. Entire Agreement; Changes in Writing. This Agreement constitutes the entire agreement among the parties hereto and supersedes and cancels any prior agreements, representations and warranties, whether oral or written, among the parties hereto relating to the transaction contemplated hereby. Neither this Agreement nor any provision hereof may be changed or amended orally, but only by an agreement in writing signed by the other party hereto.

16. Trust Waiver. HACI’s initial public offering was consummated on October 3, 2007 as a result of which it received net proceeds of $529.1 million which are held in a trust fund established by HACI for the benefit of its public stockholders (the “Trust Fund”). The Trust Fund is invested in U.S. Treasury Bills with a maturity with a maturity of 180 days or less in a trust account at JPMorgan Chase Bank, N.A. and held in trust by Continental Stock Transfer & Trust Company (the “Trustee”) pursuant to the Investment Management Trust Agreement, dated as of September 27, 2007, between HACI and Trustee. Seller understands that, except for a portion of the interest earned on the amounts held in the Trust Fund, HACI may disburse monies from the Trust Fund only: (i) to HACI in limited amounts from time to time (and in no event more than $6,555,000 in total) in order to permit HACI to pay its operating expenses; (ii) if HACI completes an initial business combination, to certain dissenting public stockholders, to the underwriters in the amount of underwriting discounts and commissions they earned in HACI’s initial public offering but whose payment they have deferred, and then to HACI; and (iii) if HACI fails to complete an initial business combination within the allotted time period and liquidates, subject to the terms of the agreement governing the Trust Fund, to HACI’s public stockholders (as such term is defined in the agreement governing the Trust Fund). Seller agrees that, notwithstanding any other provision contained in this Agreement, it does not now have, and shall not at any time prior to the consummation of the Acquisition have any claim to, or make any claim against, the Trust Fund arising out of or in connection with this Agreement or the Acquisition, regardless of whether such claim arises based on contract, tort, equity or any other theory of legal liability (any and all such claims are collectively referred to in this Section 16 as the “Claims”). Seller hereby irrevocably waives any Claim it may have, now or in the future arising under this Agreement or otherwise, and will not seek recourse

against, the Trust Fund for any reason whatsoever in respect thereof other than any amount constituting the Aggregate Purchase Price that is payable in accordance with the terms of this Agreement. This waiver is intended and shall be deemed and construed to be irrevocable and absolute on the part of Seller, and shall be binding on its subsidiaries, affiliated entities, directors, officers, employees, stockholders, representatives, advisors, all other associates and affiliates, and its and their respective heirs, successors and assigns, as the case may be. Seller acknowledges that it benefits from this Agreement and that HACI is entering into this Agreement upon reliance on this Section 16. Other than with respect to an action for the recovery of the Aggregate Purchase Price to be paid to Seller in connection with this Agreement; in the event Seller commences any other action or proceeding based upon, in connection with, relating to or arising out of any matter relating to HACI, which proceeding seeks, in whole or in part, relief against the Trust Fund or the public stockholders of HACI, whether in the form of money damages or injunctive relief, HACI shall be entitled to recover from Seller the associated legal fees and costs in connection with any such action.

17. Seller W-9. Seller agrees to provide to Buyer an Internal Revenue Service Request for Taxpayer Identification Number and Certification Form W-9.
