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


 


(a)                
Give all instructions to the Trustee hereunder
in writing, signed by the Company’s Chairman of the Board, Chief Executive Officer or Chief Financial Officer. In addition,
except with respect to its duties under paragraphs 1(i), 2(a) and 2(b) above, the Trustee shall be entitled to rely on, and shall
be protected in relying on, any verbal or telephonic advice or instruction which it in good faith believes to be given by any
one of the persons authorized above to give written instructions, provided that the Company shall promptly confirm such instructions
in writing.


 


(b)               
Subject to the provisions of Sections 5 and 7(g)
of this Agreement, hold the Trustee harmless and indemnify the Trustee from and against, any and all expenses, including reasonable
counsel fees and disbursements, or loss suffered by the Trustee in connection with any claim, potential claim, action, suit or
other proceeding brought against the Trustee involving any claim, or in connection with any claim or demand which in any way arises
out of or relates to this Agreement, the services of the Trustee hereunder, or the Property or any income earned from investment
of the Property, except for expenses and losses resulting from the Trustee’s 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 notify the Company in writing of such claim
(hereinafter referred to as the “Indemnified Claim”); provided, however, that the Trustee’s failure to provide

the Trustee shall obtain the consent of the Company with respect to the selection of counsel, which consent shall not be unreasonably

It is expressly understood that the Property shall not be used to pay such fees and further agreed that any fees owed to the Trustee
shall be deducted by the Trustee from the disbursements made to the Company pursuant to Sections 1(i) solely in connection with
the consummation of the Company’s initial acquisition, share exchange, share reconstruction and amalgamation, purchase of
all or substantially all of the assets of, or any other similar business combination with one or more businesses or entities (a
 “Business Combination”), or pursuant to Section 2 (b). The Company shall pay the Trustee the initial acceptance fee
and first year’s fee at the consummation of the IPO and thereafter on the anniversary of the Effective Date.

connection with any vote of the Company’s shareholders 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 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.


 


4.

shall have no responsibility or liability to:


 


(a)                Take
any action with respect to the Property, other than as directed in paragraphs 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
any kind with respect to, any of the Property unless and until it shall have received instructions from the Company given as provided
herein to do so and the Company shall have advanced or guaranteed to it funds sufficient to pay any expenses incident thereto;


 






     


     


    

 


(c)                Change

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 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;

the Company or any other action taken by it is as contemplated by the Registration Statement;

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 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 


 






     


     


    

 


(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.

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

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

and understanding of the parties hereto with respect to the subject matter hereof. Except for Sections 1(i), 1(k), 7(c) and 7(h)
(which may only be amended with the approval of the holders of 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 a pro-rata portion of the trust account (no less than $10.00 per
share plus the amount per share deposited in the Trust Account pursuant to any Extension Letter) in connection with any such amendment),

In
