WHEREAS, the Company’s
registration statement on Form S-1, No. 333-[__] (“Registration Statement”) for its initial public offering of securities
(“IPO”) has been declared effective as of the date hereof (“Effective Date”) by the Securities and Exchange Commission
(capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Registration Statement); and


 


WHEREAS, Chardan Capital Markets
LLC (“Chardan”) is acting as the underwriter in the IPO; and


 


WHEREAS, as described in the
Registration Statement, and in accordance with the Company’s Amended and Restated Certificate of Incorporation, $101,000,000 ($116,150,000
if the over-allotment option is exercised in full) will be delivered to the Trustee to be deposited and held in a trust account for the
benefit of the Company and the holders of the Company’s common stock, par value $.0001 per share (“Common Stock”), issued
in the IPO as hereinafter provided (the proceeds to be delivered to the Trustee will be referred to herein as the “Property”;
the stockholders for whose benefit the Trustee shall hold the Property will be referred to as the “Public Stockholders,” and
the Public Stockholders and the Company will be referred to together as the “Beneficiaries”); and

of Incorporation, the only way to extend the time available for the Company to consummate its initial Business Combination is for the
Company’s insiders or their affiliates or designees, upon five days’ advance notice prior to each applicable deadline, to

or an aggregate of $3,000,000, or $3,450,000 if the over-allotment option is exercised in full, if the time to consummate a Business Combination
is extended to a full 21 months), on or prior to the date of the applicable deadline; and


 


WHEREAS, the Company and the

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”). The Trustee shall have the right to conduct

arising out of its own gross negligence or willful misconduct;


 


(b) Institute any proceeding

any Property, other than in compliance with paragraph 1(c);

be protected in acting upon any order, notice, demand, certificate, opinion or advice of counsel (including counsel chosen by the Trustee),

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

    3

any monies in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account that it may

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,
