3.      Agreements and Covenants of
the Company. The Company hereby agrees and covenants to:


 


(a)         Give

may be the Trustee) verifying the vote of the Company’s stockholders regarding such Business Combination;


 


(e)         In
connection with the Trustee acting as Paying/Disbursing Agent pursuant to Exhibit B, the Company will not give the Trustee disbursement
instructions which would be prohibited under this Agreement;

any unexercised portion thereof) or such over-allotment option expires, provide the Trustee with a notice in writing (with a copy
to the Representative) of the total amount of the Deferred Discount, which shall in no event be less than $12,250,000; and


 


(g)         In
the event the Company is entitled to receive a tax refund on its income tax obligation, and promptly after the amount of such

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

thereto;


 


(c)         Change
the investment of any Property, other than in compliance with Section 1(c);


 


(d)         Refund
any depreciation in principal of any Property;


 


(e)         Assume
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, fraud 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 and with reasonable care, 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;


 






    	 	5	 



     

    

 


(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; and

statements with the Company documenting the taxes, if any, payable by the Company or the Trust Account, relating to the income
earned on the Property.


 


(i)          Pay
any taxes on behalf of the Trust Account (it being expressly understood that the Property shall not be used to pay any such taxes
and that such taxes, if any, shall be paid by the Company from funds not held in the Trust Account).


 


(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.

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) hereof, the Trustee shall pursue such Claim solely against the Company and not against the Property or any
monies in the Trust Account.


 


6.      Termination. This Agreement
shall terminate as follows:

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


 






    	 	6	 



     

    

 


(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.
