    WHEREAS,
      the Company has entered into an Underwriting Agreement, dated __________, 2007
      (“Underwriting Agreement”), with Lazard Capital Markets LLC (“Lazard”) acting as
      representative of the several underwriters (collectively, the “Underwriters”),
      pursuant to which, among other matters, the Underwriters have agreed to purchase
      18,000,000 units (“Units”) of the Company. Each Unit consists of one share of
      the Company’s common stock, par value $.0001 per share (“Common Stock”), and one
      Warrant to purchase one share of Common Stock, all as more fully described
      in
      the Company’s final Prospectus, dated _________, 2007 (“Prospectus”) comprising
      part of the Company’s Registration Statement on Form S-1
      (File No. 333-145759) under the Securities Act of 1933, as amended
      (“Registration Statement”), declared effective on ________, 2007 (“Effective
      Date”).

    


    WHEREAS,
      the Initial Stockholders have agreed as a condition of the sale of the Units
      to
      deposit their shares of Common Stock of the Company, as set forth opposite
      their
      respective names in Exhibit A attached hereto (collectively “Escrow Shares”), in
      escrow as hereinafter provided.

    


    WHEREAS,
      the Company and the Initial Stockholders desire that the Escrow Agent accept
      the
      Escrow Shares, in escrow, to be held and disbursed as hereinafter
      provided.

    


    IT
      IS
      AGREED:


    1. Appointment
      of Escrow Agent.
      The
      Company and the Initial Stockholders hereby appoint the Escrow Agent to act
      in
      accordance with and subject to the terms of this Agreement and the Escrow Agent
      hereby accepts such appointment and agrees to act in accordance with and subject
      to such terms.

    


    2. Deposit
      of Escrow Shares.
      On or
      before the Effective Date, each of the Initial Stockholders shall deliver to
      the
      Escrow Agent certificates representing his respective Escrow Shares, to be
      held
      and disbursed subject to the terms and conditions of this Agreement. Each
      Initial Stockholder acknowledges that the certificate representing his Escrow
      Shares is legended to reflect the deposit of such Escrow Shares under this
      Agreement.

    


    3. Disbursement
      of the Escrow Shares.
      The
      Escrow Agent shall hold the Escrow Shares until one year after the Company
      consummates a Business Combination (as such term is defined in the Registration
      Statement) (“Escrow Period”), on which date it shall, upon written instructions
      from each Initial Stockholder, disburse each of the Initial Stockholder’s Escrow
      Shares (and any applicable stock power) to such Initial Stockholder; provided,
      however, that if the Escrow Agent is notified by the Company pursuant to Section
      6.7 hereof that the Company is being liquidated at any time during the Escrow
      Period, then the Escrow Agent shall promptly destroy the certificates
      representing the Escrow Shares; provided further, that if the Underwriters
      exercise their over-allotment option to purchase an additional 2,700,000 Units
      of the Company (as described in the Prospectus), the Initial Stockholders agree
      that the Escrow Agent shall return to the Company for cancellation, at no cost,
      the number of Escrow Shares held by each Initial Stockholder determined by
      multiplying (a) the product of (i) 675,000, multiplied by (ii) a fraction,
      (x)
      the numerator of which is the number of Escrow Shares held by each Initial
      Stockholder, and (y) the denominator of which is the total number of Escrow
      Shares, by (b) a fraction, (i) the numerator of which is 2,700,000 minus the
      number of shares of Common Stock purchased by the Underwriters upon the exercise
      of their over-allotment option, and (ii) the denominator of which is 2,700,000;
      provided further, that if, after the Company consummates a Business Combination,
      (i) it (or the surviving entity) subsequently consummates a liquidation, merger,
      stock exchange or other similar transaction which results in all of the
      stockholders of such entity having the right to exchange their shares of Common
      Stock for cash, securities or other property, or (ii) the last sales price
      of a
      share of Common Stock equals or exceeds $18.00 per share for any 20 trading
      days
      within any 30-trading day period, then the Escrow Agent will, upon receipt
      of a
      certificate, executed by the Chief Executive Officer of the Company, in form
      reasonably acceptable to the Escrow Agent, that such transaction is then being
      consummated or such conditions have been achieved, release the Escrow Shares
      to
      the Initial Stockholders. The Escrow Agent shall have no further duties
      hereunder after the disbursement or destruction of the Escrow Shares in
      accordance with this Section 3.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    


    4. Rights
      of Initial Stockholders in Escrow Shares.
      

    


    4.1 Voting
      Rights as a Stockholder.
      Subject
      to the terms of the Insider Letter described in Section 4.4 hereof and except
      as
      herein provided, the Initial Stockholders shall retain all of their rights
      as
      stockholders of the Company during the Escrow Period, including, without
      limitation, the right to vote such shares.

    


    4.2 Dividends
      and Other Distributions in Respect of the Escrow Shares.
      During
      the Escrow Period, all dividends payable in cash with respect to the Escrow
      Shares shall be paid to the Initial Stockholders, but all dividends payable
      in
      stock or other non-cash property (“Non-Cash Dividends”) shall be delivered to
      the Escrow Agent to hold in accordance with the terms hereof. As used herein,
      the term “Escrow Shares” shall be deemed to include the Non-Cash Dividends
      distributed thereon, if any.

    


    4.3 Restrictions
      on Transfer.
      During
      the Escrow Period, no sale, transfer or other disposition may be made of any
      or
      all of the Escrow Shares except (i) by gift to a member of Initial Stockholder’s
      immediate family or to a trust, the beneficiary of which is an Initial
      Stockholder or a member of an Initial Stockholder’s immediate family, (ii) by
      virtue of the laws of descent and distribution upon death of any Initial
      Stockholder, or (iii) pursuant to a qualified domestic relations order;
provided,
      however,
      that
      such permissive transfers may be implemented only upon the respective
      transferee’s written agreement to be bound by the terms and conditions of this
      Agreement and of the Insider Letter signed by the Initial Stockholder
      transferring the Escrow Shares. 

    


    4.4 Insider
      Letters.
      Each of
      the Initial Stock-holders has executed a letter agreement with Lazard and the
      Company, dated as indicated on Exhibit A hereto, and which is filed as an
      exhibit to the Registration Statement (“Insider Letter”), respecting the rights
      and obligations of such Initial Stockholder in certain events, including but
      not
      limited to the liquidation of the Company.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    5. Concerning
      the Escrow Agent.

    


    5.1 Good
      Faith Reliance.
      The
      Escrow Agent shall not be liable for any action taken or omitted by it in good
      faith and in the exercise of its own best judgment, and may rely conclusively
      and shall be protected in acting upon any order, notice, demand, certificate,
      opinion or advice of counsel (including counsel chosen by the Escrow Agent),
      statement, instrument, report or other paper or document (not only as to its
      due
      execution and the validity and effectiveness of its provisions, but also as
      to
      the truth and acceptability of any information therein contained) which is
      believed by the Escrow Agent to be genuine and to be signed or presented by
      the
      proper person or persons. The Escrow Agent shall not be bound by any notice
      or
      demand, or any waiver, modification, termination or rescission of this Agreement
      unless evidenced by a writing delivered to the Escrow Agent signed by the proper
      party or parties and, if the duties or rights of the Escrow Agent are affected,
      unless it shall have given its prior written consent thereto. 

    


     5.2 Indemnification.
      The
      Escrow Agent shall be indemnified and held harmless by the Company from and
      against any expenses, including counsel fees and disbursements, or loss suffered
      by the Escrow Agent in connection with any action, suit or other proceeding
      involving any claim which in any way, directly or indirectly, arises out of
      or
      relates to this Agreement, the services of the Escrow Agent hereunder, or the
      Escrow Shares held by it hereunder, other than expenses or losses arising from
      the gross negligence or willful misconduct of the Escrow Agent. Promptly after
      the receipt by the Escrow Agent of notice of any demand or claim or the
      commencement of any action, suit or proceeding, the Escrow Agent shall notify
      the other parties hereto in writing. In the event of the receipt of such notice,
      the Escrow Agent, in its sole discretion, may commence an action in the nature
      of interpleader in an appropriate court to determine ownership or disposition
      of
      the Escrow Shares or it may deposit the Escrow Shares with the clerk of any
      appropriate court or it may retain the Escrow Shares pending receipt of a final,
      nonappealable order of a court having jurisdiction over all of the parties
      hereto directing to whom and under what circumstances the Escrow Shares are
      to
      be disbursed and delivered. The provisions of this Section 5.2 shall survive
      in
      the event the Escrow Agent resigns or is discharged pursuant to Sections 5.5
      or
      5.6 below.

    


    5.3 Compensation.
      The
      Escrow Agent shall be entitled to reasonable compensation from the Company
      for
      all services rendered by it hereunder. The Escrow Agent shall also be entitled
      to reimbursement from the Company for all expenses paid or incurred by it in
      the
      administration of its duties hereunder including, but not limited to, all
      counsel, advisors’ and agents’ fees and disbursements and all taxes or other
      governmental charges.

    


    5.4 Further
      Assurances.
      From
      time to time on and after the date hereof, the Company and the Initial
      Stockholders shall deliver or cause to be delivered to the Escrow Agent such
      further documents and instruments and shall do or cause to be done such further
      acts as the Escrow Agent shall reasonably request to carry out more effectively
      the provisions and purposes of this Agreement, to evidence compliance herewith
      or to assure itself that it is protected in acting hereunder.

    


    5.5 Resignation.
      The
      Escrow Agent may resign at any time and be discharged from its duties as escrow
      agent hereunder by its giving the other parties hereto written notice and such
      resignation shall become effective as hereinafter provided. Such resignation
      shall become effective at such time that the Escrow Agent shall turn over to
      a
      successor escrow agent appointed by the Company, the Escrow Shares held
      hereunder. If no new escrow agent is so appointed within the 60 day period
      following the giving of such notice of resignation, the Escrow Agent may deposit
      the Escrow Shares with any court it reasonably deems appropriate.

    


    5.6 Discharge
      of Escrow Agent.
      The
      Escrow Agent shall resign and be discharged from its duties as escrow agent
      hereunder if so requested in writing at any time by the other parties hereto,
      jointly, provided, however, that such resignation shall become effective only
      upon acceptance of appointment by a successor escrow agent as provided in
      Section 5.5.

    


    5.7 Liability.
      Notwithstanding anything herein to the contrary, the Escrow Agent shall not
      be
      relieved from liability hereunder for its own gross negligence or its own
      willful misconduct.

    


    5.8 Waiver.
      Notwithstanding anything herein to the contrary, the Escrow Agent hereby waives
      any and all right, title, interest or claim of any kind (“Claim”) in or to any
      distribution of the Trust Account, and hereby agrees not to seek recourse,
      reimbursement, payment or satisfaction for any Claim against the Trust Account
      for any reason whatsoever.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    
 

    6. Miscellaneous.

    


    6.1 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, without giving
      effect to conflicts of law principles that would result in the application
      of
      the substantive laws of another jurisdiction. 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.

    


    6.2 Third
      Party Beneficiaries.
      Each of
      the Initial Stockholders hereby acknowledges that the Underwriters are third
      party beneficiaries of this Agreement and this Agreement may not be modified
      or
      changed without the prior written consent of Lazard.

      Agreement.
      This
      Agreement together with the Insider Letters contain the entire agreement of

      parties hereto with respect to the subject matter hereof and, except as
      expressly provided herein, may not be changed or modified except by an
      instrument in writing signed by the party to the charged. This
      Agreement may be executed in one or more counterparts, each of which shall
      constitute an original, and together shall constitute one and the same
      instrument.

    


    6.4 Headings.
      The
      headings contained in this Agreement are for reference purposes only and shall
      not affect in any way the meaning or interpretation thereof.
