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.

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                     , 2007, between the Company, Credit Suisse Securities (USA) LLC (on behalf of the several underwriters), the portion of the Property attributable to the deferred Underwriters’ fees an amount equal to $17,500,000 (or $20,125,000 if the Underwriters’ 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.

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 Underwriters’ fees, to Credit Suisse Securities (USA) LLC (on behalf of the several underwriters); provided, however, that if the Company does not direct you to release the Underwriters’ deferred fees

In the event that the Business Combination is not consummated on the Consummation 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 business day immediately following the Consummation Date as set forth in the notice.
