      and American Stock Transfer & Trust Company, with offices at 59 Maiden Lane,
      New York, New York 10038 (the “Warrant

    WHEREAS,
      in connection with the Company’s formation, the Company issued 10,781,250 units
      (the “Founder
      Units”)
      of the Company, each unit consisting of one share of common stock of the
      Company, par value $0.001 per share (the “Common
      Stock”),
      and one warrant exercisable for one share of Common Stock, with each warrant
      evidencing the right of the holder thereof to purchase one share of Common
      Stock
      for $6.00 (the “Founder
      Warrants”),
      subject to adjustment as described herein;

    

    WHEREAS,
      the Company is engaged in a public offering (the “Public
      Offering”)
      of units of the Company, each unit consisting of one share of Common Stock
      and
      one warrant exercisable for one share of Common Stock, and in connection
      therewith, has determined to issue and deliver up to 37,500,000 units plus
      up to
      an additional 5,625,000 units if the underwriters exercise in full their
      over-allotment option (the “Public
      Units”
      and, together with the Founder Units, the “Units”)
      to the public investors for $8.00 per unit, with each warrant evidencing the
      right of the holder thereof to purchase one share of Common Stock for $6.00
      (the
“Public
      Warrants”),
      subject to adjustment as described herein; 

    

    WHEREAS,
      concurrently with the Public Offering, the Company intends to engage in a
      private offering of 6,000,000 warrants to the “Private
      Investors”
      listed on Exhibit A hereto (the “Sponsor
      Warrants”,
      and together with the Founder Warrants, the “Private
      Warrants”,
      with the Private Warrants and the Public Warrants together being the
“Warrants”),
      each evidencing the right of the holder thereof to purchase one share of Common
      Stock for $6.00, subject to adjustment as described herein;

    

    WHEREAS,
      the Company intends to file with the Securities and Exchange Commission (the
      “SEC”)
      a Registration Statement on Form S-1 (the “Registration
      Statement”)
      for the registration, under the Securities Act of 1933, as amended (the
“Act”)
      of, among other securities, the Public Warrants;

    

    WHEREAS,
      the Company desires the Warrant Agent to act on behalf of the Company, and
      the
      Warrant Agent is willing to so act, in connection with the issuance,
      registration, transfer, exchange, call, exercise and cancellation of the
      Warrants; 

    

    WHEREAS,
      the Company desires to provide for the form and provisions of the Warrants,
      the
      terms upon which they shall be issued and exercised, and the respective rights,
      limitation of rights, and immunities of the Company, the Warrant Agent, and
      the
      holders of the Warrants; and

    

    WHEREAS,
      all acts and things have been done and performed which are necessary to make
      the
      Warrants, when executed on behalf of the Company and countersigned by or on
      behalf of the Warrant Agent, as provided herein, the valid, binding and legal
      obligations of the Company, and to authorize the execution and delivery of
      this
      Agreement.

    

    NOW,
      THEREFORE, in
      consideration of the mutual agreements herein contained, the parties hereto
      agree as follows:

     

    
      
        
        

      

      
        1

        
          

        

      

      
        
        

      

    

     

    1.
      Appointment
      of Warrant Agent.
      The Company hereby appoints the Warrant Agent to act as agent for the Company
      for the Warrants, and the Warrant Agent hereby accepts such appointment and
      agrees to perform the same in accordance with the terms and conditions set
      forth
      in this Agreement.

    

    2.
      Warrants.

    

    2.1.
      Form
      of Warrant.
      Each Warrant shall be issued in registered form only, shall be in substantially
      the form of Warrant attached as Exhibit B hereto, the provisions of which are
      incorporated herein, and shall be signed by, or bear the facsimile signature
      of,
      the President and Secretary of the Company and shall bear a facsimile of the
      Company’s seal. In the event the person whose facsimile signature has been
      placed upon any Warrant shall have ceased to serve in the capacity in which
      such
      person signed the Warrant before such Warrant is issued, it may be issued with
      the same effect as if he or she had not ceased to be such at the date of
      issuance.

    

    2.2.
      Effect
      of Countersignature.
      Unless and until countersigned by the Warrant Agent pursuant to this Agreement,
      a Warrant shall be invalid and of no effect and may not be exercised by the
      holder thereof.

    

    2.3.
      Registration.

    

    2.3.1.
      Warrant
      Register.
      The Warrant Agent shall maintain books (the “Warrant
      Register”)
      for the registration of original issuance and the registration of transfers
      of
      the Warrants. Upon the initial issuance of the Warrants, the Warrant Agent
      shall
      issue and register the Warrants in the names of the respective holders thereof
      in such denominations and otherwise in accordance with instructions delivered
      to
      the Warrant Agent by the Company.

    

    2.3.2.
      Registered
      Holder.
      Prior to due presentment for registration of transfer of any Warrant, the
      Company and the Warrant Agent may deem and treat the person in whose name such
      Warrant shall be registered upon the Warrant Register (“Registered
      Holder”)
      as the absolute owner of such Warrant and of each Warrant represented thereby
      (notwithstanding any notation of ownership or other writing on the Warrant
      Certificate made by anyone other than the Company or the Warrant Agent), for
      the
      purpose of any exercise thereof and for all other purposes, and neither the
      Company nor the Warrant Agent shall be affected by any notice to the
      contrary.

    

    2.4.
      Detachability
      of Warrants.
      The securities comprising the Units will not be separately transferable until
      the
      5th
      day after the earlier to occur of the expiration of the underwriters’
over-allotment option or its exercise in full, but
      in no event will separate trading of the securities comprising the Units be
      allowed until the Company files a Current Report on Form 8-K (the “Initial
      8-K”)
      with the SEC which includes an audited balance sheet reflecting the receipt
      by
      the Company of the gross proceeds of the Public Offering, and an additional
      Current Report on Form 8-K including the proceeds received by the Company from
      the exercise of the Underwriter’s over-allotment option, if the over-allotment
      option is exercised after the filing of the Initial 8-K.

    

    2.5
      Private
      Warrants.
      The Private Warrants shall have the same terms and be in the same form as the
      Public Warrants, except that (i) the Founder Warrants will become exercisable
      after consummation of a Business Combination (as defined below) if and when
      the
      last sale price of the Common Stock on the American Stock Exchange, or other
      national securities exchange on which the Common Stock may be traded, exceeds
      $11.50 per share for any twenty (20) trading days within a thirty (30) trading
      day period beginning 90 calendar days after such Business Combination; (ii)
      the
      Founder Warrants and the Sponsor Warrants will be non-redeemable so long as
      they
      are held by the Private Investors or their Permitted Transferees (as defined
      below); (iii) the Founder Warrants will not be (and the Common Stock to be
      issued upon exercise of such warrants will not be) transferable or salable
      by
      the Private Investors or their Permitted Transferees until one year after the
      consummation of a Business Combination; and (iv) the Sponsor Warrants will
      not
      be (and the Common Stock to be issued upon exercise of such warrants will not
      be) transferable or salable by the Private Investors or their Permitted
      Transferees until the 90th
      day after the consummation of a Business Combination. “Permitted Transferees”
shall mean the recipient of a Private Warrant through a transfer by any of
      the
      Private Investors (i) by gift to a member of such transferor’s immediate family
      for estate planning purposes or to a trust, the beneficiary of which is the
      transferor or a member of the transferor’s immediate family, (ii) if the
      transferor is not a natural person, by gift to a member of the immediate family
      of such transferor’s controlling person for estate planning purposes or to a
      trust, the beneficiary of which is such transferor’s controlling person or a
      member of the immediate family of such transferor’s controlling person, (iii) by
      virtue of the laws of descent and distribution upon death of transferor, or
      (iv)
      pursuant to a qualified domestic relations order; provided, however, that such
      permitted transfers may be effected only upon the respective transferee’s
      written agreement to be bound by the same transfer restrictions as such Private
      Investor upon receiving such Warrants (except in the case of clause (iii),
      in
      which case the transferee will execute such agreement as soon as practicable
      after such transfer).

    3.
      Terms
      and Exercise of Warrants.

    

    3.1.
      Warrant
      Price.
      Each Warrant shall, when countersigned by the Warrant Agent, entitle the
      Registered Holder thereof, subject to the provisions of such Warrant and of
      this
      Agreement, to purchase from the Company the number of shares of Common Stock
      stated therein, at the price of $6.00 per whole share, subject to the
      adjustments provided in Section 4 hereof and in the last sentence of this
      Section 3.1. The term “Warrant
      Price”
      as used in this Agreement refers to the price per share at which Common Stock
      may be purchased at the time a Warrant is exercised. The Company in its sole
      discretion may lower the Warrant Price at any time prior to the Expiration
      Date
      (as defined below); provided, however, that any change in the Warrant Price must
      apply identically in percentage terms to all of the Warrants, and provided
      further that any reduction in Warrant Price must remain in effect for at least
      twenty (20) business days. 

    

    3.2.
      Duration
      of Warrants.
      A Warrant may be exercised only during the period (the “Exercise
      Period”)
      commencing on the later of (i) the completion
      of an acquisition by the Company of one or more operating businesses or assets
      through a merger, capital stock exchange, asset or stock acquisition,
      exchangeable share transaction or other similar business combination having
      collectively a fair market value of at least 80% of the Company’s net assets at
      the time of the acquisition (a “Business
      Combination”)
      and
      (ii) one year after the effective date of the Registration Statement; and all
      Warrants shall terminate at 5:00 p.m., New York City time on the earlier to
      occur of (i) four years after the effective date of the Registration Statement
      and (ii) the date fixed for calling the Warrants as provided in Section 6 of
      this Agreement (the “Expiration
      Date”);
      provided, however, that (i) the Warrants shall not be exercisable and the
      Company shall not be obligated to issue Common Stock in respect thereof unless,
      at the time a holder seeks to exercise the Warrants, a prospectus relating
      to
      the Common Stock issuable upon exercise of the Warrants is current and the
      Common Stock has been registered or qualified or deemed to be exempt under
      the
      securities laws of the state of residence of the holder of the Warrants and
      (ii)
      in addition to the exercise conditions set forth in this Section 3.2, the
      Founder Warrants may only be exercisable following the consummation of a
      Business Combination if and when the last sale price of the Common Stock on
      the
      American Stock Exchange, or other national securities exchange on which the
      Common Stock may be traded, exceeds $11.50 per share for any twenty (20) trading
      days within a thirty (30) trading day period beginning 90 calendar days after
      such Business Combination. Except with respect to the right to receive the
      Call
      Price (as set forth in Section 6 hereunder), each Warrant not exercised on
      or
      before the Expiration Date shall become void, and all rights thereunder and
      all
      rights in respect thereof under this Agreement shall cease at the close of
      business on the Expiration Date. The Company in its sole discretion may extend
      the duration of the Warrants by delaying the Expiration Date; provided, however,
      that any extension of the duration of the Warrants must apply equally to all
      of
      the Warrants. Should the Company wish to extend the Expiration Date of the
      Warrants, the Company shall provide advance notice to the American Stock
      Exchange, and shall, if possible, provide at least two (2) months advance notice
      to the American Stock Exchange, but in no event will the Company provide less
      than twenty (20) days advance notice of such extension to the American Stock
      Exchange.

    3.3.
      Exercise
      of Warrants.

    

    3.3.1.
      Payment.
      Subject to the provisions of the Warrant and this Agreement, a Warrant, when
      countersigned by the Warrant Agent, may be exercised by the Registered Holder
      thereof by surrendering it, at the office of the Warrant Agent or at the office
      of its successor as Warrant Agent, with the subscription form, as set
      forth in the Warrant, duly executed, and, except as set forth in Section 3.4,
      by
      paying in full, in lawful money of the United States, good certified check
      or
      good bank draft payable to the order of the Company (or as otherwise agreed
      to
      by the Company), the Warrant Price for each full share of Common Stock as to
      which the Warrant is exercised and any and all applicable taxes due in
      connection with the exercise of the Warrant, the exchange of the Warrant for
      the
      Common Stock and the issuance of the Common Stock.

    

    3.3.2.
      Issuance
      of Certificates.
      As soon as practicable after the exercise of any Warrant and the clearance
      of
      the funds in payment of the Warrant Price, the Company shall issue to the
      Registered Holder of such Warrant a certificate or certificates for the number
      of full shares of Common Stock to which such holder is entitled, registered
      in
      such name or names as may be directed by him, her or it, and if such Warrant
      shall not have been exercised in full, a new countersigned Warrant for the
      number of shares as to which such Warrant shall not have been exercised.
      Notwithstanding the foregoing, the Company shall not be obligated to deliver
      any
      securities pursuant to the exercise of a Warrant, and shall have no obligation
      to settle the Warrant exercise unless a registration statement under the Act
      with respect to the Common Stock is effective, subject to the Company satisfying
      its obligations under Section 7.4 to use its best efforts. In the event that
      a
      registration statement with respect to the Common Stock underlying a Warrant
      is
      not effective under the Act, the holder of such Warrant shall not be entitled
      to
      exercise such Warrant. Notwithstanding anything to the contrary contained in
      this Agreement, under no circumstances will the Company be required to net
      cash
      settle the exercise of the Warrants. Warrants may not be exercised by, and
      securities may not be issued to, any Registered Holder in any jurisdiction
      in
      which such exercise would be unlawful. As a result of the provisions of this
      Section 3.3.2, any or all of the Warrants may expire unexercised. In no event
      shall the Registered Holder of a Warrant be entitled to receive any monetary
      damages if the shares of Common Stock underlying the Warrants have not been
      registered by the Company pursuant to an effective registration statement or
      if
      a current prospectus is not available for delivery by the Warrant Agent;
      provided that the Company has fulfilled its obligation to use its best efforts
      to effect such registration and ensure a current prospectus is available for
      delivery by the Warrant Agent.

    

    3.3.3.
      Valid
      Issuance.
      All shares of Common Stock issued upon the proper exercise of a Warrant in
      conformity with this Agreement shall be validly issued, fully paid and
      nonassessable.

    

    3.3.4.
      Date
      of Issuance.
      Each person in whose name any such certificate for shares of Common Stock is
      issued shall for all purposes be deemed to have become the holder of record
      of
      such shares on the date on which the Warrant was surrendered and payment of
      the
      Warrant Price was made, irrespective of the date of delivery of such
      certificate, except that, if the date of such surrender and payment is a date
      when the stock transfer books of the Company are closed, such person shall
      be
      deemed to have become the holder of such shares at the close of business on
      the
      next succeeding date on which the stock transfer books are open.

    3.4.
      Cashless
      Exercise.

    

    3.4.1.
      Determination
      of Amount.
      In lieu of the payment of the Warrant Price, a Registered Holder shall have
      the
      right (but not the obligation) to convert any exercisable but unexercised
      Warrants into shares of Common Stock (the “Conversion
      Right”)
      as follows: upon exercise of the Conversion Right, the Company shall deliver
      to
      the holder (without payment by the holder of any of the Warrant Price in cash)
      that number of shares of Common Stock equal to the quotient obtained by dividing
      (x) the Value (as defined below) of the Warrants being exercised by (y) the
      Current Market Value (as defined below). The “Value” of the Warrants being
      exercised shall equal the amount derived from subtracting (a) (i) the Warrant
      Price multiplied by (ii) the number of shares of Common Stock issuable upon
      exercise of the Warrants being converted from (b) (i) the Current Market Value
      of a share of Common Stock multiplied by (ii) the number of shares of Common
      Stock issuable upon exercise of the Warrants being converted. As used herein,
      the term “Current
      Market Value”
      per share of Common Stock at any date shall mean the average last sale price
      of
      the Common Stock for the ten (10) trading days ending on the third trading
      day
      prior to the date on which the Warrant Agent receives notice of the Registered
      Holder’s exercise of the Conversion Right in the principal trading market for
      the Common Stock as reported by any national securities exchange or quoted
      on
      the NASD OTC Bulletin Board (or its successor entity), as the case may be;
      provided, that if the fair market value of the Common Stock cannot be so
      determined, the “Current Market Value” per share shall be determined by the
      Board of Directors of the Company, in good faith. 

    

    3.4.2.
      Mechanics
      Of Cashless Exercise.
      The Conversion Right may be exercised by a Registered Holder during the Exercise
      Period by surrendering the Warrant with the duly executed exercise form attached
      thereto with the cashless exercise section completed to the Warrant Agent,
      exercising the Conversion Right and specifying the total number of shares of
      Common Stock the Registered Holder will purchase pursuant to such Conversion
      Right; provided
      that any holder that holds Warrants in a brokerage account shall follow the
      procedures of such holder’s broker and the Depository Trust Company in order to
      exercise the Conversion Right.

    

    4.
      Adjustments.

    

    4.1.
      Stock
      Dividends; Split-Ups.
      If after the consummation of the Public Offering, and subject to the provisions
      of Section 4.6 below, the number of outstanding shares of Common Stock is
      increased by a stock dividend payable in shares of Common Stock, or by a
      split-up of shares of Common Stock, or other similar event, then, on the
      effective date of such stock dividend, split-up or similar event, the number
      of
      shares of Common Stock issuable on exercise of each Warrant shall be increased
      in proportion to such increase in outstanding shares of Common
      Stock.

    

    4.2.
      Aggregation
      of Shares.
      If after the consummation of the Public Offering, and subject to the provisions
      of Section 4.6, the number of outstanding shares of Common Stock is decreased
      by
      a consolidation, combination, reverse stock split or reclassification of shares
      of Common Stock or other similar event, then, on the effective date of such
      consolidation, combination, reverse stock split, reclassification or similar
      event, the number of shares of Common Stock issuable on exercise of each Warrant
      shall be decreased in proportion to such decrease in outstanding shares of
      Common Stock.

    

    4.3.
      Adjustments
      in Exercise Price.
      Whenever the number of shares of Common Stock purchasable upon the exercise
      of
      the Warrants is adjusted, as provided in Sections 4.1 and 4.2 above, the Warrant
      Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price
      immediately prior to such adjustment by a fraction (x) the numerator of which
      shall be the number of shares of Common Stock purchasable upon the exercise
      of
      the Warrants immediately prior to such adjustment, and (y) the denominator
      of
      which shall be the number of shares of Common Stock so purchasable immediately
      thereafter.

      Replacement
      of Securities upon Reorganization.
      In case of any reclassification or reorganization of the outstanding shares
      of
      Common Stock (other than a change covered by Sections 4.1 or 4.2 hereof or
      that
      solely affects the par value of such shares of Common Stock), or in the case
      of
      any merger or consolidation of the Company with or into another corporation
      (other than a consolidation or merger in which the Company is the continuing
      corporation and that does not result in any reclassification or reorganization
      of the outstanding shares of Common Stock), or in the case of any sale or
      conveyance to another corporation or entity of the assets or other property
      of
      the Company as an entirety or substantially as an entirety in connection with
      which the Company is dissolved, the Warrant holders shall thereafter have the
      right to purchase and receive, upon the basis and upon the terms and conditions
      specified in the Warrants and in lieu of the shares of Common Stock of the
      Company immediately theretofore purchasable and receivable upon the exercise
      of
      the rights represented thereby, the kind and amount of shares of stock or other
      securities or property (including cash) receivable upon such reclassification,
      reorganization, merger or consolidation, or upon a dissolution following any
      such sale or transfer, that the Warrant holder would have received if such
      Warrant holder had exercised his, her or its Warrant(s) immediately prior to
      such event; and if any reclassification also results in a change in shares
      of
      Common Stock covered by Sections 4.1 or 4.2, then such adjustment shall be
      made
      pursuant to Sections 4.1, 4.2, 4.3 and this Section 4.4. The provisions of
      this
      Section 4.4 shall similarly apply to successive reclassifications,
      reorganizations, mergers or consolidations, sales or other
      transfers.

    

    4.5.
      Notices
      of Changes in Warrant.
      Upon every adjustment of the Warrant Price or the number of shares issuable
      upon
      exercise of a Warrant, the Company shall give written notice thereof to the
      Warrant Agent, which notice shall state the Warrant Price resulting from such
      adjustment and the increase or decrease, if any, in the number of shares
      purchasable at such price upon the exercise of a Warrant, setting forth in
      reasonable detail the method of calculation and the facts upon which such
      calculation is based. Upon the occurrence of any event specified in Sections
      4.1, 4.2, 4.3 or 4.4, then, in any such event, the Company shall give written
      notice to each Warrant holder, at the last address set forth for such holder
      in
      the Warrant Register, of the record date or the effective date of the event.
      Failure to give such notice, or any defect therein, shall not affect the
      legality or validity of such event.

    

    4.6.
      No
      Fractional Shares.
      Notwithstanding any provision contained in this Agreement to the contrary,
      the
      Company shall not issue fractional shares upon exercise of Warrants. If, by
      reason of any adjustment made pursuant to this Section 4, the holder of any
      Warrant would be entitled, upon the exercise of such Warrant, to receive a
      fractional interest in a share, the Company shall, upon such exercise, round
      up
      or down to the nearest whole number the number of the shares of Common Stock
      to
      be issued to the Warrant holder.

    

    4.7.
      Form
      of Warrant.
      The form of Warrant need not be changed because of any adjustment pursuant
      to
      this Section 4, and Warrants issued after such adjustment may state the same
      Warrant Price and the same number of shares as is stated in the Warrants
      initially issued pursuant to this Agreement. However, the Company may at any
      time in its sole discretion make any change in the form of Warrant that the
      Company may deem appropriate and that does not affect the substance thereof,
      and
      any Warrant thereafter issued or countersigned, whether in exchange or
      substitution for an outstanding Warrant or otherwise, may be in the form as
      so
      changed.

    

    4.8.
      Extraordinary
      Dividends.
      If the Company, at any time during the Exercise Period, shall pay a dividend
      or
      make a distribution in cash, securities or other assets to the holders of Common
      Stock (or other shares of the Company’s capital stock into which the Warrants
      are convertible), other than (w) as described in Sections 4.1, 4.2 or 4.4,
      (x)
      regular quarterly or other periodic dividends, (y) in connection with the
      conversion rights of the holders of Common Stock upon consummation of a Business
      Combination or (z) in connection with the Company’s liquidation and the
      distribution of its assets upon its failure to consummate a Business Combination
      (any such non-excluded event being referred to herein as an “Extraordinary
      Dividend”),
      then the Warrant Price shall be decreased, effective immediately after the
      effective date of such Extraordinary Dividend, by the amount of cash and/or
      the
      fair market value (as determined by the Company’s Board of Directors, in good
      faith) of any securities or other assets paid on each share of Common Stock
      in
      respect of such Extraordinary Dividend.

    4.9.
      Notice
      of Certain Transactions.
      In the event that the Company shall (a) offer to holders of its Common Stock
      rights to subscribe for or to purchase any securities convertible into shares
      of
      Common Stock or shares of stock of any class or any other securities, rights
      or
      options, (b) issue any rights, options or warrants entitling the holders of
      Common Stock to subscribe for shares of Common Stock or (c) make a tender offer,
      redemption offer or exchange offer with respect to the Common Stock, the Company
      shall send to the Warrant holders a notice of such action or offer. Such notice
      shall be mailed to the Registered Holders at their addresses as they appear
      in
      the Warrant Register, which shall specify the record date for the purposes
      of
      such dividend, distribution or rights, or the date such issuance or event is
      to
      take place and the date of participation therein by the holders of Common Stock,
      if any such date is to be fixed, and shall briefly indicate the effect of such
      action on the Common Stock and on the number and kind of any other shares of
      stock and on other property, if any, and the number of shares of Common Stock
      and other property, if any, issuable upon exercise of each Warrant and the
      Warrant Price after giving effect to any adjustment pursuant to this Section
      4
      which would be required as a result of such action. Such notice shall be given
      as promptly as practicable after the Company has taken any such
      action.

    

    5.
      Transfer
      and Exchange of Warrants.

    

    5.1.
      Registration
      of Transfer.
      The Warrant Agent shall register the transfer, from time to time, of any
      outstanding Warrant upon the Warrant Register, upon surrender of such Warrant
      for transfer, properly endorsed with signatures properly guaranteed and
      accompanied by appropriate instructions for transfer. Upon any such transfer,
      a
      new Warrant representing an equal aggregate number of Warrants shall be issued
      and the old Warrant shall be cancelled by the Warrant Agent. The Warrants so
      cancelled shall be delivered by the Warrant Agent to the Company from time
      to
      time upon request.

    

    5.2.
      Procedure
      for Surrender of Warrants.
      Warrants may be surrendered to the Warrant Agent, together with a written
      request for exchange or transfer, and thereupon the Warrant Agent shall issue
      in
      exchange therefor one or more new Warrants as requested by the Registered Holder
      of the Warrants so surrendered, representing an equal aggregate number of
      Warrants; provided, however, that in the event that a Warrant surrendered for
      transfer bears a restrictive legend, the Warrant Agent shall not cancel such
      Warrant and issue new Warrants in exchange therefor until the Warrant Agent
      has
      received an opinion of counsel for the Company stating that such transfer may
      be
      made and indicating whether the new Warrants must also bear a restrictive
      legend.

    

    5.3.
      Fractional
      Warrants.
      The Warrant Agent shall not be required to effect any registration of transfer
      or exchange which will result in the issuance of a warrant certificate for
      a
      fraction of a warrant.

    

    5.4.
      Service
      Charges.
      No service charge shall apply to any holder of Warrants for any exchange or
      registration of transfer of Warrants.

    

    5.5.
      Warrant
      Execution and Countersignature.
      The Warrant Agent is hereby authorized to countersign and to deliver, in
      accordance with the terms of this Agreement, the Warrants required to be issued
      pursuant to the provisions of this Section 5, and the Company, whenever required
      by the Warrant Agent, will supply the Warrant Agent with Warrants duly executed
      on behalf of the Company for such purpose.

    6.
      Call.

    

    6.1.
      Call.
      Subject to Section 6.4 hereof, not less than all of the outstanding Warrants
      may
      be called, at the option of the Company, at any time after they become
      exercisable and prior to their expiration, at the office of the Warrant Agent,
      upon the notice referred to in Section 6.2, at the price of $.01 per Warrant
      (the “Call
      Price”),
      provided that (i) the last sale price of the Common Stock on the American Stock
      Exchange, or other national securities exchange on which the Common Stock may
      be
      traded, has been at least $11.50 per share (the “Trigger
      Price”)
      on each of twenty (20) trading days within any thirty (30) trading day period
      ending on the third business day prior to the date on which notice of the call
      is given (the “Measurement
      Period”)
      and (ii) the Public Warrants and the Common Stock underlying such Warrants
      are
      covered by an effective registration statement and a current prospectus from
      the
      beginning of the Measurement Period through the date fixed for the call;
      provided, further, that with respect to the Founder Warrants and the Sponsor
      Warrants, such call right shall not be applicable so long as such Warrants
      are
      held by any of the Private Investors or their Permitted
      Transferees.

    

    6.2.
      Call
      Date; Notice of Call.
      In the event the Company shall elect to call all of the Warrants, the Company
      shall fix a date for the call, which date shall be prior to the expiration
      of
      the Warrants (the “Call
      Date”).
      Notice of the call shall be mailed by first class mail, postage prepaid, by
      the
      Company not less than thirty (30) days prior to the date fixed for the call
      to
      the Registered Holders of the Warrants to be called at their last addresses
      as
      they shall appear in the Warrant Register. Any notice mailed in the manner
      herein provided shall be conclusively presumed to have been duly given on the
      date sent whether or not the Registered Holder received such notice. In the
      event of any adjustment to the Warrant Price or the number of shares of Common
      Stock issuable on exercise of each Warrant as provided in Section 4, a
      proportional adjustment shall be made to the Trigger Price.

    

    6.3.
      Exercise
      after Notice of the Call.
      The Warrants may be exercised for cash at any time after notice of the call
      shall have been given by the Company pursuant to Section 6.2 hereof and prior
      to
      the Call Date. On and after the Call Date, the record holder of the Warrants
      shall have no further rights except to receive, upon surrender of the Warrants,
      the Call Price.

    

    6.4
      Outstanding
      Warrants Only.
      The Company understands that the call rights provided for in this Section 6
      apply only to outstanding Warrants. To the extent a person holds rights to
      purchase Warrants, such purchase rights shall not be extinguished by the call.
      However, once such purchase rights are exercised, the Company may call the
      Warrants issued upon such exercise provided that the criteria for the call
      set
      forth in Section 6.1 are met.

    

    7.
      Other
      Provisions Relating to Rights of Holders of Warrants.

    

    7.1.
      No
      Rights as Stockholder.
      A Warrant does not entitle the Registered Holder thereof to any of the rights
      of
      a stockholder of the Company, including, without limitation, receiving dividends
      or other distributions, exercising any preemptive rights to vote or to consent
      or to receive notice as stockholders in respect of the meetings of stockholders
      or the election of directors of the Company or any other matter. 

    

    7.2.
      Lost,
      Stolen, Mutilated, or Destroyed Warrants.
      If any Warrant is lost, stolen, mutilated or destroyed, the Company and the
      Warrant Agent may on such terms as to indemnity or otherwise as they may in
      their discretion impose (which shall, in the case of a mutilated Warrant,
      include the surrender thereof), issue a new Warrant of like denomination, tenor,
      and date as the Warrant so lost, stolen, mutilated or destroyed. Any such new
      Warrant shall constitute a substitute contractual obligation of the Company,
      whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall
      be at any time enforceable by anyone.

    

    7.3.
      Reservation
      of Common Stock.
      The Company shall at all times reserve and keep available a number of its
      authorized but unissued shares of Common Stock that will be sufficient to permit
      the exercise in full of all outstanding Warrants issued pursuant to this
      Agreement.

    7.4.
      Registration
      of Common Stock.
      The Company agrees that, prior to the commencement of the Exercise Period,
      it
      shall file with the SEC a new registration statement, for the registration
      under
      the Act of, and it shall take such action as is necessary to qualify for sale,
      in those states in which the Public Warrants were initially offered by the
      Company, the Common Stock issuable upon exercise of the Public Warrants. In
      either case, the Company will use its best efforts to cause the same to become
      effective on or prior to the commencement of the Exercise Period and use its
      best efforts to maintain the effectiveness of such registration statement and
      ensure that a current prospectus is on file with the SEC until the expiration
      of
      the Warrants in accordance with the provisions of this Agreement; provided,
      however, that the Company shall not be obligated to deliver securities, and
      shall not have penalties for failure to deliver securities, if a registration
      statement is not effective or a current prospectus is not on file with the
      SEC
      at the time of exercise by the holder. 

    

    7.5.
      Delivery
      of Prospectus or Notice.
      Upon the exercise of any Warrant, if the Company requests, the Warrant Agent
      shall deliver to the Holder of such Warrant, prior to or concurrently with
      the
      delivery of the shares of Common Stock issued upon such exercise, in accordance
      with the Company’s request, either (i) a prospectus relating to the shares of
      Common Stock deliverable upon exercise of Warrants and complying in all material
      respects with the Act or (ii) the notice referred to in Rule 173 under the

      Payment
      of Taxes.

      may
      be imposed upon the Company or the Warrant Agent in respect of the issuance
      or
      delivery of shares of Common Stock upon the exercise of Warrants, but the
      Company shall not be obligated to pay any transfer taxes in respect of the
      Warrants or such shares of Common Stock.

    

    8.2.
      Resignation,
      Consolidation or Merger of Warrant Agent.

    

    8.2.1.
      Appointment
      of Successor Warrant Agent.
      The Warrant Agent, or any successor to it hereafter appointed, may resign its
      duties and be discharged from all further duties and liabilities hereunder
      after
      giving sixty (60) days’ notice in writing to the Company. If the office of the
      Warrant Agent becomes vacant by resignation or incapacity to act or otherwise,
      the Company shall appoint in writing a successor Warrant Agent in place of
      the
      Warrant Agent. If the Company shall fail to make such appointment within a
      period of sixty (60) days after it has been notified in writing of such
      resignation or incapacity by the Warrant Agent or by the holder of a Warrant
      (who shall, with such notice, submit his Warrant for inspection by the Company),
      then the holder of any Warrant may apply to the Supreme Court of the State
      of
      New York for the County of New York for the appointment of a successor Warrant
      Agent at the Company’s cost. Any successor Warrant Agent, whether appointed by
      the Company or by such court, shall be a corporation organized and existing
      under the laws of the State of New York in good standing and having its
      principal office in the Borough of Manhattan, City and State of New York, and
      shall be authorized under such laws to exercise corporate trust powers and
      subject to supervision or examination by federal or state authority. After
      appointment, any successor Warrant Agent shall be vested with all the authority,
      powers, rights, immunities, duties and obligations of its predecessor Warrant
      Agent with like effect as if originally named as Warrant Agent hereunder,
      without any further act or deed; but if for any reason it becomes necessary
      or
      appropriate, the predecessor Warrant Agent shall execute and deliver, at the
      expense of the Company, an instrument transferring to such successor Warrant
      Agent all the authority, powers, rights, immunities, duties and obligations
      of
      such predecessor Warrant Agent hereunder; and upon request of any successor
      Warrant Agent, the Company shall make, execute, acknowledge and deliver any
      and
      all instruments in writing for more fully and effectually vesting in and
      confirming to such successor Warrant Agent all such authority, powers, rights,
      immunities, duties and obligations.

      give notice thereof to the predecessor Warrant Agent, Credit Suisse Securities
      (USA) LLC (“Credit
      Suisse”)
      and the transfer agent for the Common Stock not later than the effective date
      of
      any such appointment.

    

    8.2.3.
      Merger
      or Consolidation of Warrant Agent.
      Any corporation into which the Warrant Agent may be merged or with which it
      may
      be consolidated or any corporation resulting from any merger or consolidation
      to
      which the Warrant Agent shall be a party shall be the successor Warrant Agent
      under this Agreement, without any further act or deed.

    

    8.3.
      Fees
      and Expenses of Warrant Agent.

    

    8.3.1.
      Remuneration.
      The Company agrees to pay the Warrant Agent reasonable remuneration for its
      services as Warrant Agent hereunder and will reimburse the Warrant Agent upon
      demand for all expenditures that the Warrant Agent may reasonably incur in
      the
      execution of its duties hereunder.

    

    8.3.2.
      Further
      Assurances.
      The Company agrees to perform, execute, acknowledge and deliver or cause to
      be
      performed, executed, acknowledged and delivered all such further and other
      acts,
      instruments, and assurances as may reasonably be required by the Warrant Agent

      of Warrant Agent.

    

    8.4.1.
      Reliance
      on Company Statement.
      Whenever in the performance of its duties under this Agreement, the Warrant
      Agent shall deem it necessary or desirable that any fact or matter be proved
      or
      established by the Company prior to taking or suffering any action hereunder,
      such fact or matter (unless other evidence in respect thereof be herein
      specifically prescribed) may be deemed to be conclusively proved and established
      by a statement signed by the Chief Executive Officer or Chairman of the Board
      of
      Directors of the Company and delivered to the Warrant Agent. The Warrant Agent
      may rely upon such statement for any action taken or suffered in good faith
      by
      it pursuant to the provisions of this Agreement.

    

    8.4.2.
      Indemnity.
      The Warrant Agent shall be liable hereunder only for its own negligence, willful
      misconduct or bad faith. The Company agrees to indemnify the Warrant Agent
      and
      save it harmless against any and all liabilities, including judgments, costs
      and
      reasonable counsel fees, for anything done or omitted by the Warrant Agent
      in
      the execution of this Agreement except as a result of the Warrant Agent’s
      negligence, willful misconduct or bad faith.

    

    8.4.3.
      Exclusions.
      The Warrant Agent shall have no responsibility with respect to the validity
      of
      this Agreement or with respect to the validity or execution of any Warrant
      (except its countersignature thereof); nor shall it be responsible for any
      breach by the Company of any covenant or condition contained in this Agreement
      or in any Warrant; nor shall it be responsible to make any adjustments required
      under the provisions of Section 4 hereof or responsible for the manner, method
      or amount of any such adjustment or the ascertaining of the existence of facts
      that would require any such adjustment; nor shall it by any act hereunder be
      deemed to make any representation or warranty as to the authorization or
      reservation of any shares of Common Stock to be issued pursuant to this
      Agreement or any Warrant or as to whether any shares of Common Stock will,
      when
      issued, be valid and fully paid and nonassessable.

    

    8.5.
      Acceptance
      of Agency.
      The Warrant Agent hereby accepts the agency established by this Agreement and
      agrees to perform the same upon the terms and conditions herein set forth and,

      on
      contract, tort or otherwise) arising out of, connected with or relating to
      this
      Agreement, the transactions contemplated hereby, or the actions of the Investor
      in the negotiation, administration, performance or enforcement
      hereof.

      with respect to Sections 2.5, 6.1, 6.4, 7.4 and 9.2 hereof. All covenants,
      conditions, stipulations, promises, and agreements contained in this Agreement

      their successors and assigns and the Registered Holders of the

    9.7.
      Counterparts.
      This Agreement may be executed in any number of original or facsimile
      counterparts and each of such counterparts shall for all purposes be deemed
      to
      be an original, and all such counterparts shall together constitute but one

      Amendments.
      This Agreement may be amended by the parties hereto without the consent of

      any other provisions with respect to matters or questions arising under this
      Agreement as the parties may deem necessary or desirable and that the parties
      deem shall not adversely affect the interest of the Registered Holders. All

      of the then outstanding Warrants. Notwithstanding the foregoing, the Company
      may
      lower the Warrant Price or extend the duration of the Exercise Period in

      Statement”)
      for
      its initial public offering of securities (the “IPO”)
      has
      been declared effective as of the date hereof (the “Effective
      Date”)
      by the
      Securities and Exchange Commission;

     

    WHEREAS,
      Credit Suisse Securities (USA) LLC (“Credit
      Suisse”)
      is
      acting as underwriter in the IPO (the “Underwriter”);

     

    WHEREAS,
      as described in the Registration Statement, and in accordance with the Company’s
      Amended and Restated Certificate of Incorporation, (i) approximately
      $294,460,000 (approximately $337,885,000 if the Underwriter’s over-allotment
      option is exercised in full) to be received by the Company in connection with
      the IPO, plus (ii) $6,000,000 to be received by the Company in connection with

      which will be paid from the Trust Account to the Underwriter upon the
      consummation of a Business Combination; and

     

    WHEREAS,

      Company that any interest income should be set aside to pay taxes in accordance
      with Section 1(j);

     

    (j) Upon

    2. Agreements
      and Covenants of the Company.
      The

    (a) Give
      all instructions to the Trustee hereunder in writing, signed by the
      Company’s
      Chief
      Executive Officer;

     

    (b) Hold
      the
      Trustee harmless, defend and indemnify the Trustee from and against any and
      all
      expenses, including reasonable counsel fees and disbursements, or loss suffered

      against the Trustee involving any claim, or in connection with any claim or
      demand which in any way arises out of or relates to this Agreement, the services
      of the Trustee hereunder, or the Property or any income earned from investment
      of the Property, except for expenses and losses resulting from the Trustee’s
      gross negligence or willful misconduct. Promptly after the receipt by the
      Trustee of notice of demand or claim or the commencement of any action, suit
      or
      proceeding, pursuant to which the Trustee intends to seek indemnification under
      this paragraph, it shall notify the Company in writing of such claim
      (hereinafter referred to as the “Indemnified Claim”). The Company shall conduct

      Trustee may voluntarily participate in such action at its own cost with its
      own
      counsel;

     

    (c) Pay
      the
      Trustee an initial acceptance fee of $3,000 (it being expressly understood
      that
      the Property shall not be used to pay such fee). The Company shall pay the
      Trustee the initial acceptance fee at the consummation of the IPO. The Company
      shall not be responsible for any other fees or charges of the Trustee except
      as
      may be provided in paragraph 2(b) hereof (it being expressly understood that
      the
      Property shall not be used to make any payments to the Trustee under such
      paragraph). The Trustee shall refund to the Company the fee (on a pro rata
      basis) with respect to any period after the liquidation of the Trust Fund;
      and

     

    (d) In
      connection with any vote of the Company’s stockholders regarding a Business
      Combination, provide to the Trustee an affidavit or certificate of a firm
      regularly engaged in the business of soliciting proxies and tabulating
      stockholder votes verifying the vote of the Company’s stockholders regarding
      such Business Combination.

     

    3. Limitations
      of Liability.
      The
      Trustee shall have no responsibility or liability to:

      any action with respect to the Property, other than as directed in paragraph
      1
      hereof,
      and the
      Trustee shall have no liability to any party under this Agreement except for
      liability arising out of its own gross negligence or willful
      misconduct;

     

    (b) Institute
      any proceeding for the collection of any principal and income arising from,
      or

      any
      of the Property unless and until it shall have received written instructions
      from the Company given as provided herein to do so and the Company shall have
      advanced or guaranteed to it funds sufficient to pay any expenses incident
      thereto;

     

    (c) Change
      the investment of any Property, other than in compliance with paragraph
      1(c);

    (d) Refund
      any depreciation in principal of any Property invested in accordance with
      Section 1(c);

     

    (e) Assume
      that the authority of any person designated by the Company to give instructions
      hereunder shall not be continuing unless provided otherwise in such designation,
      or unless the Company shall have delivered a written revocation of such
      authority to the Trustee;

     

    (f) The
      other
      parties hereto or anyone else for any action taken or omitted by it in
      compliance with this Agreement, or any action suffered by it to be taken or
      omitted in compliance with this Agreement made in good faith and in the exercise
      of its best judgment, except for its gross negligence or willful misconduct.
      The
      Trustee 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 Trustee), 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 Trustee, in good faith, to be
      genuine and to be signed or presented by the proper person or persons. The
      Trustee shall not be bound by any notice or demand, or any waiver, modification,
      termination or rescission of this Agreement or any of the terms hereof, unless
      evidenced by a written instrument delivered to the Trustee signed by the proper
      party or parties and, if the duties or rights of the Trustee are affected,
      unless it shall give its prior written consent thereto; 

     

    (g) Verify
      the correctness of the information set forth in the Registration Statement
      or to
      confirm or assure that any acquisition made by the Company or any other action
      taken by it is as contemplated by the Registration Statement; or

     

    (h) Look
      to
      any other agreement for the determination of its duties as Trustee.

     

    4. Termination.
      This
      Agreement shall terminate as follows:

     

    (a) If
      the Trustee gives written notice to the Company that it desires to resign under
      this Agreement, the Company shall use its reasonable efforts to locate a
      successor trustee. At such time that the Company notifies the Trustee that
      a
      successor trustee has been appointed by the Company and has agreed to become
      subject to the terms of this Agreement, the Trustee shall transfer the
      management of the Trust Account to the successor trustee, including but not
      limited to the transfer of copies of the reports and statements relating to
      the
      Trust Account, whereupon this Agreement shall terminate,
      except
      that the provisions of Section 2(b) shall survive termination; provided,
      however, that in the event that the Company does not locate a successor trustee
      within ninety (90) days of receipt of the resignation notice from the Trustee,
      the Trustee may, upon written notice to the Company, submit an application
      to
      have the Property deposited with the United States District Court for the
      Southern District of New York and, upon such deposit, the Trustee shall be
      immune from any liability whatsoever that arises due to any actions or omissions
      to act by any party after such deposit; or

     

    (b) At
      such
      time that the Trustee has completed the liquidation of the Trust Account in
      accordance with the provisions of paragraph 1(k) hereof and distributed the
      Property in accordance with the provisions of the Termination Letter, this
      Agreement shall terminate except with respect to Paragraph 2(b).

     

    5. Miscellaneous.

     

    (a) The
      Company and the Trustee each acknowledge that the Trustee will follow the
      security procedures set forth below with respect to funds transferred from
      the
      Trust Account. Upon receipt of written instructions, the Trustee will confirm
      such instructions with an Authorized Individual at an Authorized Telephone
      Number listed on the attached Exhibit C. The Company and the Trustee will each
      restrict access to confidential information relating to such security procedures
      to authorized persons. Each party must notify the other party immediately if
      it
      has reason to believe unauthorized persons may have obtained access to such
      information
      and of
      any change in its authorized personnel.

    (b) This
      Agreement may be executed by facsimile and in several counterparts, which
      together shall constitute but one instrument.

     

    (c) This
      Agreement contains the entire agreement and understanding of the parties hereto
      with respect to the subject matter hereof. This Agreement or any provision
      hereof may only be changed, amended or modified by a writing signed by each
      of
      the parties hereto; provided that such action shall not materially adversely
      affect the interests of the Public Stockholders. Any change, waiver, amendment
      or modification to this Agreement that materially adversely affects the
      interests of the Public Stockholders shall be subject to approval by each of
      the
      Public Stockholders materially adversely affected thereby. As to any claim,
      cross-claim or counterclaim in any way relating to this Agreement, each party
      waives the right to trial by jury.

     

    (d) This
      Agreement shall be governed by, and construed in accordance with, the laws
      of
      the State of New York applicable to contracts executed in and to be performed
      in
      that State, including, without limitation, Sections 5-1401 and 5-1402 of the
      New
      York General Obligations Law and the New York Civil Practice Laws and Rules
      327(b). The parties hereto agree 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 the parties hereto irrevocably
      submit to such jurisdiction, which jurisdiction shall be exclusive. The parties
      hereto hereby waive any objection to such exclusive jurisdiction and that such
      courts represent an inconvenient forum.

     

    (e) Any
      notice, consent or request to be given in connection with any of the terms
      or
      provisions of this Agreement shall be in writing and shall be sent by certified

    Gentlemen:

     

    Pursuant
      to paragraph 1(k) of the Investment Management Trust Agreement between
      Greenstreet Acquisition Corp. (the “Company”)
      and
      American Stock Transfer & Trust Company (the “Trustee”),
      dated
      as of [_________], 2008 (the “Trust
      Agreement”),
      this
      is to advise you that the Company has entered into an agreement (the “Business
      Agreement”) with ____________________ (the “Target”)
      to
      consummate a business combination with the Target (the “Business
      Combination”)
      on or
      about [insert date]. The Company shall notify you at least forty-eight (48)
      hours in advance of the actual date of the consummation of the Business
      Combination (the “Consummation
      Date”).
      Defined terms used but not otherwise defined herein shall have the meaning
      ascribed to such term in the Trust Agreement.

     

    Pursuant
      to Section 2(d) of the Trust Agreement, we are providing you with [an affidavit]
      [a certificate] of ____________________, which verifies the vote of the
      Company’s stockholders in connection with the Business Combination. In
      accordance with the terms of the Trust Agreement, we hereby authorize you to
      commence liquidation of the Trust Account to the effect that, on the
      Consummation Date, all of the funds held in the Trust Account will be
      immediately available for transfer to the account or accounts that the Company
      and Credit Suisse Securities (USA) LLC shall direct in writing on the
      Consummation Date.

     

    On
      the
      Consummation Date (i) counsel for the Company (“Company
      Counsel”)
      shall
      deliver to you written notification that the Business Combination has been
      consummated and (ii) the Company shall deliver to you written instructions
      (the
“Instruction
      Letter”)
      with
      respect to the transfer of the funds held in the Trust Account, including,
      but
      not limited to, (a) funds to be delivered to any Public Stockholder that has
      properly exercised its conversion rights (as described in the Registration
      Statement), (b) pursuant to the terms of the Underwriting Agreement, dated
      as of
      [____________], 2008, between the Company and Credit Suisse Securities (USA)
      LLC, the portion of the Property attributable to the deferred Underwriter’s fees
      an amount equal to $10,500,000 (or $12,075,000 if the Underwriter’s
      over-allotment option is exercised in full) and (c) the portion of the Property
      to be released to the Company in connection with the consummation of the
      Business Combination. 

     

    You
      are
      hereby directed and authorized to transfer the funds held in the Trust Account
      immediately upon your receipt of Company Counsel’s notification and the
      Instruction Letter, in accordance with the terms of the Instruction Letter.
      In
      the event that certain deposits held in the Trust Account may not be liquidated
      by the Consummation Date without penalty, you will notify the Company of the
      same and the Company shall direct you as to whether such funds should remain
      in
      the Trust Account and be distributed after the Consummation Date to the Company
      or, with respect to the deferred Underwriter’s fees, to Credit Suisse Securities
      (USA) LLC; provided, however, that if the Company does not direct you to release
      the Underwriter’s deferred fees within ten days after the Consummation Date, you
      shall release such Underwriter’s deferred fees to Credit Suisse Securities (USA)
      LLC upon a written request from Credit Suisse Securities (USA) LLC. Upon the
      distribution of all the funds in the Trust Account pursuant to the terms hereof,
      the Trust Agreement shall be terminated.

      Date
      described in the notice thereof and we have not notified you on or before the
      original Consummation Date of a new Consummation Date, then the funds held
      in
      the Trust Account shall be reinvested as provided in the Trust Agreement on
      the
