the Underwriters have agreed to deposit in the Trust Account (defined below)

Company), the Trustee shall upon receipt from the Company of a written
request disburse to the Company, on or about the first business day of each

     (j)  Upon written instructions from the Company, deliver to the Company or

a quarterly basis, from the Property in the Trust Account, an amount equal to
the taxes payable by the Company, if any, relating to interest earned on the
Property; and

     (k)  Commence liquidation of the Trust Account promptly after receipt of

accordance with the procedures set forth in the Termination Letter attached
as EXHIBIT B to the stockholders of record on the record date; PROVIDED,
FURTHER, that the record date shall be within ten (10) days of October 17,
2008 (or the date that is six months following such date, in the event that a

any one of the persons authorized above to give written instructions, provided
that the Company shall promptly confirm such instructions in writing;

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

anniversary of the Effective Date. The Trustee shall refund to the Company the
fee (on a pro rata basis) with respect to any period after the liquidation of

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);

     (d)  Provide to the Trustee any letter of intent, agreement in principle
or definitive agreement that is executed prior to October 17, 2008 in

willful misconduct;

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

     (f)  The other parties hereto or to anyone else for any action taken or
omitted by it, or any action suffered by it to be taken or omitted, in good
faith and in the exercise of its own 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; or

     (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.

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; 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

                                        4
<Page>

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, 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 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 other change,
waiver, amendment or modification to this Agreement shall be subject to approval
by a majority of the Public Stockholders. 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 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. 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 irrevocably submit to such jurisdiction, which jurisdiction
shall be exclusive. The parties 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 express mail or similar

[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
("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(e) 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

     On the Consummation Date (i) counsel for the Company shall deliver to you

that certain deposits held in the Trust Account may not be liquidated by the

Deutsche Bank. Upon the distribution of all the funds in the Trust Account
pursuant to the terms hereof, the Trust Agreement shall be terminated.

     In the event that the Business Combination is not consummated on the
