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

(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/or tabulating stockholder votes verifying
the vote of the Company’s stockholders 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; and


 


(f)        If
the Company seeks to amend any provisions of Article Sixth of its amended and restated certificate of incorporation (in each case,

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 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;

local, state and/or federal tax returns or information returns with any taxing authority on behalf of the Trust Account and payee
statements with the Company documenting the taxes, if any, payable by the Company or the Trust Account, relating to the income

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; or


 


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


 



    5 


     


    

 


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


 


(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).


 


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. 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 all information supplied to it by the Company, including account names, account numbers
and all other identifying information relating to a beneficiary, beneficiary’s bank or intermediary bank. The Trustee shall
not be liable for any loss, liability or expense resulting from any error in the information or transmission of the wire.


 


(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. This
Agreement may be executed in several original or facsimile counterparts, each one of which shall constitute an original, and together
shall constitute but one instrument.

be changed, amended or modified by a writing signed by each of the parties hereto; provided, however, that no such change, amendment

in any way relating to this Agreement, each party waives the right to trial by jury. The Trustee may require from Company counsel
an opinion as to the propriety of any proposed amendment.

In
