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

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 such notice shall not relieve the Company of its liability hereunder, except to the
extent that it is materially prejudiced by such failure. The Trustee shall have the right to conduct and manage the defense against
such Indemnified Claim, provided, that the Trustee shall obtain the consent of the Company with respect to the selection of counsel,
which consent shall not be unreasonably withheld. The Trustee may not agree to settle any Indemnified Claim without the prior
written consent of the Company, which consent shall not be unreasonably withheld or delayed. The Company may participate in such
action with its own counsel.

the Trustee an initial acceptance fee, an annual fee and a transaction processing fee for each disbursement made pursuant to Sections

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.


 


(d)       In
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.             Limitations of Liability. The Trustee shall have no responsibility or liability to:

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

    3


     


    

 


(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;


 


(h)       File

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 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

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


 


(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.

original, and together shall constitute but one instrument.

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 account JPMorgan Chase Bank, N.A. to the effect that, on the Consummation Date, all of funds held in the

vote  of  the  Company’s  shareholders in connection with the Business Combination if a vote is held

and authorized to transfer the funds held in the Trust Account immediately upon your receipt of the counsel’s letter and
the Instruction Letter, in accordance with the terms of the Instruction Letter. In the event that certain deposits held in the

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.
