WARRANT PURCHASE AGREEMENT

WARRANT PURCHASE AGREEMENT (this “Agreement”) made as of this 11^th day of February, 2008 by and among United Services Management Corporation, a Delaware corporation (the “Company”), and each of the purchasers named on Schedule A hereto (each, a “Purchaser” and collectively, the “Purchasers”).

WHEREAS, the Company has filed or will file with the Securities and Exchange Commission (the “SEC”) a registration statement on Form S-1 (the “Registration Statement”), in connection with the Company’s initial public offering (the “IPO”) of up to 16,000,000 units (the “Units”), each unit consisting of one share of the Company’s common stock, $.0001 par value (the “Common Stock”), and (ii) one warrant, each warrant to purchase one share of Common Stock; and

WHEREAS, concurrently with the IPO the Company desires to sell in a private placement to the Purchasers (the “Placement”) an aggregate of 4,100,000 warrants (the “Placement Warrants”) substantially similar to the warrants being issued in the IPO pursuant to the terms and conditions hereof and as set forth in the Registration Statement, except that the Placement Warrants, and the shares of Common Stock underlying the Placement Warrants (the “Underlying Shares” and, together with the Placement Warrants, the “Securities”), to be issued in the Placement shall not be registered under the Securities Act of 1933, as amended (the “Securities Act”); and

WHEREAS, the Purchasers are entitled to registration rights with respect to the Placement Warrants and the Underlying Shares on the terms set forth in this Agreement; and

WHEREAS, except as provided herein, the Placement Warrants shall be governed by the Warrant Agreement filed as an exhibit to the Registration Statement (the “Warrant Agreement”) and will be entitled to the benefits of a Registration Rights Agreement filed as an exhibit to the Registration Statement.

NOW, THEREFORE, for and in consideration of the premises and the mutual covenants hereinafter set forth, the parties hereto do hereby agree as follows:

1. Purchase of Placement Warrants. The Purchasers hereby agree, directly or through their respective nominees, severally and not jointly, to purchase an aggregate of 4,100,000 Placement Warrants at a purchase price of $1.00 per Placement Warrant, for an aggregate of $4,100,000 (the “Purchase Price”). Each Purchaser shall purchase the number of Placement Warrants and pay the portion of the Purchase Price set forth opposite such Purchaser’s name on Exhibit A hereto.

2. Closing. The closing of the purchase and sale of the Placement Warrants (the “Closing”) will take place at the offices of the Company, on or prior to the closing date of the IPO (the “Closing Date”), provided the underwriting agreement is signed and executed with the representative of the underwriters. On or prior to the Closing Date, each Purchaser shall pay its portion of the Purchase Price set forth opposite such Purchaser’s name on Exhibit A in immediately available funds by wire transfer or such

other form of payment as shall be acceptable to the trustee, to the trust account maintained by Continental Stock Transfer & Trust Company, acting as trustee (the “Trust Account”). The certificates for the Placement Warrants shall be delivered to the Purchasers promptly after the payment of the Purchase Price.

3. Lock-Up Agreement. Prior to the date following the consummation of an initial business combination (as defined in the Registration Statement), each Purchaser shall not (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or file (or participate in the filing of) a registration statement with the SEC in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the SEC promulgated thereunder (the “Exchange Act”) with respect to, any Placement Warrants and the Underlying Shares, or any securities convertible into or exercisable or exchangeable for shares, or warrants or other rights to purchase shares or any such securities, or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of Placement Warrants or Underlying Shares or any securities convertible into or exercisable or exchangeable for shares, or warrants or other rights to purchase shares or any such securities, whether any such transaction is to be settled by delivery of shares or such other securities, in cash or otherwise (collectively “Transfer”), provided, however, that each Purchaser shall be allowed, on condition that prior to such Transfer, each permitted transferee or the trustee or legal guardian for each permitted transferee agrees in writing to be bound by the terms of this Agreement: (a) transfers to the Company’s officers and directors; (b) transfers to any of the Company’s initial stockholders that held shares of Common Stock prior to the consummation of the IPO; and (c) transfers to any affiliates of the Company’s officers, directors and initial stockholders.

4. Placement Warrants Non-Redeemable. The Placement Warrants shall be non-redeemable and may be exercised on a cashless basis so long as the Purchasers or their affiliates hold such Placement Warrants following their issuance by the Company to the Purchasers.

5. Representations and Warranties of the Purchasers. Each Purchaser hereby represents and warrants to the Company with respect solely to itself and not with respect to any other Purchaser that:

5.1 Each Purchaser has all necessary power and authority to enter into this Agreement and to consummate the transactions contemplated hereby. All actions necessary to be taken by each Purchaser to authorize the execution, delivery and performance of this Agreement and all other agreements and instruments delivered by each Purchaser in connection with the transactions contemplated hereby have been duly and validly taken, and this Agreement has been duly executed and delivered by each Purchaser. This Agreement constitutes the valid, binding and enforceable obligation of each Purchaser, enforceable in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or similar laws of general application now or hereafter in effect affecting the

2

rights and remedies of creditors and by general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity). The execution and delivery by each Purchaser of this Agreement and the fulfillment of and compliance with the respective terms hereof by each Purchaser do not and shall not as of the Closing conflict with or result in a breach of the terms, conditions or provisions of any other agreement, instrument, order, judgment or decree to which such Purchaser is subject.

5.2 Each Purchaser is an “accredited investor” as that term is defined in Rule 501 of Regulation D promulgated under the Securities Act and acknowledges the sale contemplated hereby is being made in reliance on a private placement exemption to “Accredited Investors” within the meaning of Section 501(a) of Regulation D under the Securities Act or similar exemptions under state law; and, accordingly, such Securities will be “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, and therefore may not be offered, pledged or sold by it, directly or indirectly, in the United States without registration under United States federal and state securities laws and Purchaser understands the certificates representing such Securities will contain a legend in respect of such restrictions.

5.3 The Securities are being acquired for such Purchaser’s own account and not with a view to, or for resale in connection with, any distribution or public offering thereof within the meaning of the Securities Act. Each Purchaser shall not engage in hedging transactions with regard to the Securities unless in compliance with the Securities Act.

5.4 Each Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities nor have such authorities passed upon or endorsed the merits of the offering of the Securities.

5.5 Each Purchaser is familiar with the Company’s business plans and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Each Purchaser has been afforded the opportunity to ask questions of the executive officers and directors of the Company. Each Purchaser understands that its investment in the Securities involves a high degree of risk. Each Purchaser has sought such accounting, legal and tax advice as each Purchaser has considered necessary to make an informed investment decision with respect to each Purchaser’s acquisition of the Securities. Each Purchaser has such knowledge and expertise in financial and business matters, knows of the high degree of risk associated with investments generally and particularly investments in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and risks of an investment in the Securities, and is able to bear the economic risk of an investment in the Securities in the amount contemplated hereunder.

5.6 Each Purchaser understands that the Securities have not been registered under the Securities Act or any state securities law by reason of a specific exemption therefrom, and that the Company is relying on the truth and accuracy of, and each Purchaser’s compliance with, the representations and warranties and agreements of each

3

Purchaser set forth herein to determine the availability of such exemptions and the eligibility of each Purchaser to acquire such Securities, including, but not limited to, the bona fide nature of each Purchaser’s investment intent as expressed herein.

5.7 Each Purchaser did not decide to enter into this Agreement as a result of any general solicitation or general advertising within the meaning of Rule 502(c) of the Securities Act.
