THIS SECURITIES PURCHASE AGREEMENT (this “Agreement”), dated as of February 1, 2008, is entered into by and among Greenhill & Co., Inc., a Delaware corporation (the “Seller”), and the purchasers identified on Exhibit A hereto (each, a “Purchaser” and collectively, the “Purchasers”).

WHEREAS, GHL Acquisition Corp. (the “Company”) has filed a registration statement (the “Registration Statement”) for the initial public offering of its units (the “Initial Public Offering”), each unit consisting of one share of the Company’s common stock, par value $0.001 per share (a “Share”), and one warrant to purchase one Share at an exercise price of $7.50 per Share.

WHEREAS, the Seller owns 9,775,000 units (the “Founder’s Units”), each unit consisting of one Share (the “Founder’s Shares”), and one warrant to purchase one Share at an exercise price of $7.50 per share (the “Founder’s Warrants”).

WHEREAS, concurrently with the execution and delivery of this Agreement, the Seller desires to sell certain of the Founder’s Units to the Purchasers in the respective amounts set forth opposite each Purchaser’s name on Exhibit A hereto, and the Purchasers desire to purchase the Founder’s Units from the Seller in the respective amounts set forth opposite each Purchaser’s name on Exhibit A hereto, all upon the terms and conditions hereof.

NOW THEREFORE, in consideration of the mutual promises contained in this Agreement and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement hereby agree as follows:

Section 1. Authorization, Purchase and Sale; Terms of the Founder’s Units, Founder’s Shares and Founder’s Warrants.

A. Purchase and Sale of the Founder’s Units. Concurrently with the execution and delivery of this Agreement or as such date may be extended from time to time by mutual agreement of the parties (the “Closing Date”), the Seller shall sell, assign and transfer the Founder’s Units (consisting of the Founder’s Shares and the Founder’s Warrants) it is selling hereunder to each Purchaser, free and clear of all liens, other than restrictions as may be imposed pursuant to state or federal securities laws, in consideration of the payment of the Purchase Price (as defined below). On the Closing Date, the Seller shall deliver certificates evidencing the Founder’s Units, Founder’s Shares and Founder’s Warrants to be purchased by each Purchaser

hereunder upon the payment by each Purchaser of the amounts set forth opposite each Purchaser’s name on Exhibit A hereto, in the aggregate amount of $384.00 (the “Purchase Price”), by wire transfer of immediately available funds (or by such other means as the Seller and such Purchaser shall agree) to the Seller in accordance with the Seller’s wiring instructions.

B. Terms of the Founder’s Units, Founder’s Shares and Founder’s Warrants.

(i) Founder’s Units: Each Unit of the Founder’s Units shall consist of one Founder’s Share and one Founder’s Warrant and shall have the terms set forth in the Unit Certificate attached as Exhibit B hereto.

(ii) Founder’s Shares: The Founder’s Shares shall have the terms set forth in the Certificate of Incorporation of the Company and the Founder’s Share Certificate attached as Exhibit C hereto. Without limiting the foregoing, each Purchaser hereby expressly agrees that if the Company consummates the Initial Public Offering, then (i) in connection with the stockholder vote required to approve a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses or assets (an “Initial Business Combination”) and the related amendment to the Amended and Restated Certificate of Incorporation of the Company to provide for the Company’s perpetual existence, such Purchaser agrees to vote the Founder’s Shares in accordance with a majority of the shares of common stock voted by holders of shares of common stock issued in the Initial Public Offering and (ii) each Purchaser agrees to waive any right to participate in any liquidation distribution to the extent set forth in Section 3.D of this Agreement.

(iii) Founder’s Warrants: The Founder’s Warrants shall have the terms set forth in the Warrant Agreement set forth as Exhibit D hereto.

(iv) Transfer Restrictions: In addition to the restrictions on transfer set forth in Section 8 hereof, each Purchaser shall not sell or transfer the Founder’s Units, Founder’s Shares, Founder’s Warrants and the Shares underlying the Founder’s Warrants for a period of 180 days from the date the Company completes its Initial Business Combination except to the Seller, a Company executive officer, director or employee, or any other person or entity associated or affiliated with the Seller (each, a “Permitted Transferee”), who agrees in writing with the Company to be subject to such transfer restrictions, vote the Founder’s Shares as provided in Section 1.B.(ii) above; waive any right to participate in any liquidation distribution as provided in Section 1.B.(ii) above and agrees to the adjustment of the Founder’s Units as provided in Section 1.B.(vi) below. During this period, each Purchaser and its Permitted Transferees shall retain all other rights of holders of Shares, including, without limitation, the right to vote their Shares (except as described above with respect to an Initial Business Combination) and the right to receive cash dividends, if declared. If dividends are declared and payable in Shares, such dividends will also be subject to the restrictions contained in this Section 1.B.(v).

(v) Registration Rights: In connection with the closing of the Initial Public Offering, the Purchasers shall enter into an agreement with the Company (the “Registration Rights Agreement”) granting the Purchasers registration rights with respect to each of the Founder’s Units, Founder’s Shares, Founder’s Warrants and the Shares underlying the Founder’s Warrants (collectively, the “Securities”).

(vi) Adjustment of Founder’s Units:

(a) If the underwriters with respect to the Initial Public Offering do not exercise the over-allotment option in whole or in part proposed to be granted to them by the Company, each Purchaser and any Permitted Transferees agree to forfeit to the Company, in such proportion as such Purchaser holds of the total outstanding Founder’s Units immediately prior to the Initial Public Offering, a number of Founder’s Units necessary to ensure that the aggregate amount of Founder’s Shares held by the Seller, the Purchasers and any Permitted Transferees does not exceed approximately 17.5% of the issued and outstanding common stock of the Company upon consummation of the Initial Public Offering. Each Purchaser and any Permitted Transferees agree to take any and all action reasonably requested by the Company necessary to effect any adjustment pursuant to this Section 1.B.(vi)(a). The Company will not make any cash payment to the Purchasers or any Permitted Transferees in respect of any such adjustment.

(b) If the number of units offered to the public in connection with the Initial Public Offering is increased or decreased, each Purchaser and any Permitted Transferees agree that the Founder’s Units (including the Founder’s Units subject to forfeiture) purchased by such Purchaser hereunder will be adjusted in the same proportion as the increase or decrease of the units offered to the public in order to ensure that the aggregate amount of Founder’s Shares held by the Seller, the Purchasers and any Permitted Transferees does not fall below or exceed approximately 17.5% of the issued and outstanding common stock of the Company upon consummation of the Initial Public Offering (including any shares of common stock issued pursuant to the underwriters’ over-allotment option). Each Purchaser and any Permitted Transferees agree to take any and all action reasonably requested by the Company necessary to effect any adjustment pursuant to this Section 1.B.(vi)(b); provided that the Company will not make or receive any cash payment to or from the Purchasers or any Permitted Transferees in respect of any such adjustment.

(c) Each Purchaser acknowledges and agrees that any additional units it may hold pursuant to Sections 1.B.(vi)(a) and 1.B.(vi)(b) above (A) shall be subject to the voting, waiver of liquidation, transfer restrictions and adjustment provisions set forth in this Agreement, and (B) shall bear the legend set forth in Section 8.A.(i) below.

Section 3. Representations and Warranties of the Purchaser.

As a material inducement to the Seller to enter into this Agreement and sell the Founder’s Units, each Purchaser hereby represents and warrants to the Seller as of the date hereof and the Closing Date that:

A. Capacity and State Law Compliance. Such Purchaser has engaged in the transactions contemplated by this Agreement within a state in which the offer and sale of the Securities is permitted under applicable securities laws. Such Purchaser understands and acknowledges that the purchase of Shares upon the exercise of the Founder’s Warrants will require the availability of an exemption from registration under federal and/or state securities laws and that any sale of such Shares shall require registration or the availability of an exemption from registration under federal and/or state securities laws.

B. Authorization; No Breach.

(i) This Agreement constitutes a valid and binding obligation of such Purchaser, enforceable in accordance with its terms.

(ii) The execution and delivery by such Purchaser of this Agreement and the fulfillment of and compliance with the respective terms hereof by such Purchaser do not and shall not as of the Closing Date conflict with or result in a breach of the terms, conditions or provisions of any agreement, instrument, order, judgment or decree to which such Purchaser is subject.

C. Investment Representations.

(i) Such Purchaser is acquiring the Securities for its own account, for investment only and not with a view towards, or for resale in connection with, any public sale or distribution thereof.

(ii) Such Purchaser is an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D.

(iii) Such Purchaser understands that the Securities are being offered and will be sold to it in reliance on specific exemptions from the registration requirements of the United States federal and state securities laws and that the Seller is relying upon the truth and accuracy of, and such Purchaser’s compliance with, the representations and warranties of such Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of such Purchaser to acquire such Securities.

(iv) Such 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) under the Securities Act of 1933, as amended (the “Securities Act”).

(v) Such Purchaser has been furnished with all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Securities which have been requested by such Purchaser. Such

6

Purchaser has been afforded the opportunity to ask questions of the executive officers and directors of the Company. Such Purchaser understands that its investment in the Securities involves a high degree of risk. Such Purchaser has sought such accounting, legal and tax advice as such Purchaser has considered necessary to make an informed investment decision with respect to such Purchaser’s acquisition of the Securities.

(vi) Such 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 by such Purchaser nor have such authorities passed upon or endorsed the merits of the offering of the Securities.

(vii) Such Purchaser understands that: (a) the Securities have not been and are not being registered under the Securities Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (A) subsequently registered thereunder or (B) sold in reliance on an exemption therefrom; and (b) except as specifically set forth in the Registration Rights Agreement, neither the Company nor any other person is under any obligation to register the Securities under the Securities Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder. In this regard, such Purchaser understands that the Securities and Exchange Commission has taken the position that promoters or affiliates of a blank check company and their transferees, both before and after an Initial Business Combination, are deemed to be “underwriters” under the Securities Act when reselling the securities of a blank check company. Based on that position, Rule 144 adopted pursuant to the Securities Act would not be available for resale transactions of the Securities despite technical compliance with the requirements of such Rule, and the Securities can be resold only through a registered offering or in reliance upon another exemption from the registration requirements of the Securities Act. Such Purchaser is able to bear the economic risk of its investment in the Securities for an indefinite period of time.

(viii) Such 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. Such Purchaser has adequate means of providing for its current financial needs and contingencies and will have no current or anticipated future needs for liquidity which would be jeopardized by the investment in the Securities. Such Purchaser can afford a complete loss of its investment in the Securities.

D. Waiver of Right to Amounts in the Trust Account and Indemnification.

(i) Such Purchaser hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the trust account established by the Company for the deposit of proceeds from the Initial Public Offering and the sale of

7

warrants in a private placement to occur concurrently with the closing of the Initial Public Offering, as a result of any liquidation of the trust account, with respect to the Founder’s Shares (“Claim”) and hereby waives any Claim it may have in the future as a result of, or arising out of, any contracts or agreements with the Company or the Seller and will not seek recourse against the trust account for any reason whatsoever except for any amounts to which it may be entitled upon liquidation of the Company in respect of such Purchaser’s ownership of Shares other than the Founder’s Shares.

(ii) Such Purchaser acknowledges and agrees that the stockholders of the Company, including those who purchase the units in the Initial Public Offering, are and shall be third-party beneficiaries of the foregoing provision of Section 3.D. of this Agreement.

(iii) Such Purchaser agrees that to the extent any waiver of rights under this Section 3.D. is ineffective as a matter of law, such Purchaser has offered such waiver for the benefit of the Company and the Seller as an equitable right that shall survive any statutory disqualification or bar that applies to a legal right. Such Purchaser acknowledges the receipt and sufficiency of consideration received from the Seller hereunder in this regard.

E. Extent of Representations and Warranties. Notwithstanding any other provision of this Section 3, each representation and warranty made by the Purchasers hereunder should be deemed to be made severally, and not jointly.

Section 4. Conditions of the Purchasers’ Obligations.

The obligation of each Purchaser to purchase and pay for the Founder’s Units is subject to the fulfillment, on or before the Closing Date, of each of the following conditions:
