or certificate of a firm regularly engaged in the business of soliciting proxies and/or tabulating shareholder votes verifying
the vote of the Company’s shareholders regarding such Business Combination.


 


(e)               In
the event that the Company directs the Trustee to commence liquidation of the Trust Account pursuant to Section 1(i), the
Company agrees that it will not direct the Trustee to make any payments that are not specifically authorized by this Agreement.

(a)               Take
any action with respect to the Property, other than as directed in Sections 1 and 2 hereof and the Trustee shall have no liability
to any party 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 institute, appear in or defend any proceeding of

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 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;


 


(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;

earned on the Property;

such taxes and that such taxes, if any, shall be paid by the Company from funds not held in the Trust Account or released to it
under Section 2(a) hereof);


 


(j)               
Imply obligations, perform duties, inquire or otherwise be subject to the provisions of any agreement or document other
than this agreement and that which is expressly set forth herein; and


 


(k)               Verify
calculations, qualify or otherwise approve Company requests for distributions pursuant to Section 1(i), 1(k), 2(a) or
2(b) above.


 


5.           
Trust Account Waiver. The Trustee has no right of set-off or any right, title, interest or claim of any kind (“Claim”)
to, or to any monies in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account
that it may have now or in the future. In the event the Trustee has any Claim against the Company under this Agreement, including,
without limitation, under Section 3(b) or Section 3(c) hereof, the Trustee shall pursue such Claim solely against
the Company and its assets outside the Trust Account and not against the Property or any monies in the Trust Account.


 


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 during which time the Trustee shall act in accordance with this Agreement. 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 District of New York and upon such
deposit, the Trustee shall be immune from any liability whatsoever; or


 






    4


     


    

 


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

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. 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

at least 50% of the shares of Common Stock sold in the IPO, provided that all Public Shareholders must be given the right to receive

in advance of the actual date of the consummation of the Business Combination (“Consummation Date”). Capitalized terms
used herein and not otherwise defined shall have the meanings set forth in the Trust Agreement.


 


In accordance with the terms of the Trust
Agreement, we hereby authorize you to liquidate the Trust Account investments and to transfer the proceeds to the above-referenced

be immediately available for transfer to the account or accounts that the Company shall direct on the Consummation Date. It is
acknowledged and agreed that while the funds are on deposit in the trust operating account awaiting distribution, the Company will
not earn any interest or dividends.


 


On the Consummation Date (i) counsel

Company shall deliver to you a certificate by the Chief Executive Office, which verifies the vote of the Company’s shareholders
in connection with the Business Combination if a vote is held and (b) joint written instructions from the Company and the

no less than $10.00 per share to redeeming Public Shareholders (“Instruction Letter”). You are hereby directed and

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 distributed after the Consummation Date to the
Company. Upon the distribution of all the funds in the Trust Account pursuant to the terms hereof, the Trust Agreement shall be
terminated.
