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;

(h)                                 File information returns with the United States Internal Revenue Service and payee statements with the Company, documenting the taxes payable by the Company, if any, relating to interest earned on the Property; and

5.                                       Trust Account Waiver. The Trustee has no right, title, interest, or claim of any kind (“Claim”) in or to any monies in the Trust Account, and hereby waives any Claim in or to any monies in the Trust Account it may have in the future, and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against the Trust Account for any reason whatsoever.

6.                                       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; provided, however, that, in the event that the Company does not locate a successor trustee within ninety days of receipt of the resignation notice from the Trustee, the Trustee may submit an application to have the Property deposited with any court in the State of New York or with the United States District Court for the Southern

5

District of New York and upon such deposit, the Trustee shall be immune from any liability whatsoever; or

(b)                                 At such time that the Trustee has completed the liquidation of the Trust Account in accordance with the provisions of paragraph 1(i) hereof, and distributed the Property in accordance with the provisions of the Termination Letter, this Agreement shall terminate except with respect to Paragraph 3(b).

7.                                       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 E. 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, or of any change in its authorized personnel. In executing funds transfers, the Trustee will rely upon account numbers or other identifying numbers of a beneficiary, beneficiary’s bank or intermediary bank, rather than names. The Trustee shall not be liable for any loss, liability or expense resulting from any error in an account number or other identifying number, provided it has accurately transmitted the numbers provided.

(b)                                 This Agreement shall be governed by and construed and enforced 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. It may be executed in several original or facsimile counterparts, each one of which shall constitute an original, and 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. Except for Section 1(i) (which may not be amended under any circumstances), this Agreement or any provision hereof may only be changed, amended or modified by a writing signed by each of the parties hereto; provided, however, that no such change, amendment or modification may be made without the prior written consent of CRT. 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)                                 The parties hereto consent to the jurisdiction and venue of any state or federal court located in the City of New York, Borough of Manhattan, for purposes of resolving any disputes hereunder.

(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 express mail or similar private courier service, by certified mail (return receipt requested), by hand delivery or by facsimile transmission:
