Ladies
and Gentlemen:

 

Aquaron
Acquisition Corp. (the “Company”), a blank check company formed for the purpose of acquiring one or more businesses or entities
(a “Business Combination”), intends to register its securities under the Securities Act of 1933, as amended (“Securities
Act”), in connection with its initial public offering (“IPO”), pursuant to a registration statement on Form S-1 (“Registration
Statement”).

 

The
undersigned hereby commits that it will purchase 231,250 units of the Company (“Placement Units”), each Placement Unit consisting
of one share of common stock of the Company, $0.0001 par value (the “Common Stock”), one warrant entitling its holder to
purchase one half (1/2) of one share of Common Stock, and one right to receive one-twentieth (1/20) of one share of Common Stock upon
the consummation of an initial Business Combination, at $10.00 per Placement Unit, for a purchase price of $2,812,500 (the “Placement
Unit Purchase Price”).

 

The
undersigned hereby agrees that it will purchase an additional amount of units of the Company (“Over-Allotment Units”), up
to a maximum of 18,750 Over-Allotment Units, or a maximum purchase price of $187,500 (“Over-Allotment Unit Purchase Price”,
together with the Placement Unit Purchase Price, the “Purchase Price”), in the event that Chardan Capital Markets, LLC (the
“Underwriter”) exercises its over-allotment option, such that the amount held in the trust account (as described in the Registration
Statement, the “Trust Account”) does not fall below $10.10 per share for each share of Common Stock sold in the IPO.

 

At
least twenty-four (24) hours prior to the pricing of the IPO, the undersigned will cause the Purchase Price to be delivered to an escrow
account with Loeb & Loeb LLP (“Loeb”).

 

The
consummation of the purchase and issuance of the Placement Units shall occur simultaneously with the consummation of the IPO and the
consummation of the purchase and issuance of the Over-Allotment Units shall occur simultaneously with the closing of any exercise of
the over-allotment option related to the IPO. Simultaneously with or prior to the consummation of the IPO, Loeb shall deposit the Private
Unit Purchase Price, without interest or deduction, into the Trust Account.

 

Each
of the Company, and the undersigned acknowledges and agrees that Loeb is serving hereunder solely as a convenience to the parties to
facilitate the purchase of the Placement Units and Loeb’s sole obligation under this letter agreement is to act with respect to
holding and disbursing the Purchase Price for the Placement Units as described above. Loeb shall not be liable to the Company, the Underwriter
or the undersigned or any other person or entity in respect of any act or failure to act hereunder or otherwise in connection with performing
its services hereunder unless Loeb has acted in a manner constituting gross negligence or willful misconduct. The Company and the undersigned
shall indemnify Loeb against any claim made against it (including reasonable attorney’s fees) by reason of it acting or failing
to act in connection with this letter agreement except as a result of its gross negligence or willful misconduct. Loeb may rely and shall
be protected in acting or refraining from acting upon any written notice, instruction or request furnished to it hereunder and believed
by it to be genuine and to have been signed or presented by the proper party or parties. 

 

The
Units and Over-Allotment Units will be identical to the units to be sold by the Company in the IPO. Additionally, the undersigned agrees:

 

	 	●	to vote the shares of Common
    Stock included in the Placement Units and Over-Allotment Units in favor of any proposed Business Combination;
	 	 	 
	 	●	not to propose, or vote
    in favor of, an amendment to the Company’s Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”)
    that would affect the substance or timing of the Company’s obligation to redeem 100% of the Company’s shares of Common
    Stock sold in the IPO if the Company does not complete an initial Business Combination within 12 months from the closing of the IPO
    (or 15 or 18 months, as applicable), unless the Company provides the holders of shares of Common Stock underlying the units sold
    in the IPO with the opportunity to redeem their shares of Common Stock upon approval of any such amendment at a per-share price,
    payable in cash, equal to the aggregate amount of the Trust Account, including interest earned on Trust Account and not previously
    released to the Company to pay the Company’s franchise and income taxes, divided by the number of then outstanding shares of
    Common Stock underlying the units sold in the IPO;

 

     

     

    

 

	 	●	not to convert any shares
    of Common Stock included in the Placement Units and Over-Allotment Units into the right to receive cash from the Trust Account in
    connection with a stockholder vote to approve either a Business Combination or an amendment to the provisions of the Certificate
    of Incorporation, and not to tender any shares of Common Stock included in the Placement Units and Over-Allotment Units in connection
    with a tender offer conducted prior to the closing of a Business Combination;

 

	 	●	that the undersigned will
    not participate in any liquidation distribution with respect to the Placement Units and Over-Allotment Units or any underlying securities
    (but will participate in liquidation distributions with respect to any units or shares of Common Stock purchased by the undersigned
    in the IPO or in the open market) if the Company fails to consummate a Business Combination;

 

	 	●	that the Placement Units,
    Over-Allotment Units and underlying securities will not be transferable until after the consummation of a Business Combination except
    (i) to the Company’s pre-IPO stockholders, or to the Company’s officers, directors, advisors and employees, (ii) transfers
    to the undersigned’s affiliates or its members upon its liquidation, (iii) to relatives and trusts for estate planning purposes,
    (iv) by virtue of the laws of descent and distribution upon death, (v) pursuant to a qualified domestic relations order, (vi) by
    private sales made in connection with the consummation of a Business Combination at prices no greater than the price at which the
    Placement Units were originally purchased or (vii) to the Company for cancellation in connection with the consummation of a Business
    Combination, in each case (except for clause vii) where the transferee agrees to the terms of the transfer restrictions; and

 

	 	●	the Placement Units and
    Over-Allotment Units will include any additional terms or restrictions as is customary in other similarly structured blank check
    company offerings or as may be reasonably required by the underwriters in the IPO in order to consummate the IPO, each of which will
    be set forth in the Registration Statement.

  

The
undersigned acknowledges and agrees that the purchaser of the Placement Units and Over-Allotment Units will execute agreements in form
and substance typical for transactions of this nature necessary to effectuate the foregoing agreements and obligations prior to the consummation
of the IPO as are reasonably acceptable to the undersigned, including but not limited to an insider letter.

 

The
undersigned hereby represents and warrants that:

 

	 	(a)	it has been advised that
    the Placement Units and Over-Allotment Units have not been registered under the Securities Act;

 

	 	(b)	it will be acquiring the
    Placement Units and Over-Allotment Units for its account for investment purposes only;

    the terms and conditions of the offer made hereunder;

 

	 	(f)	it is familiar with the
    proposed business, management, financial condition and affairs of the Company;

 

	 	(g)	it has full power, authority
    and legal capacity to execute and deliver this letter and any documents contemplated herein or needed to consummate the transactions
    contemplated in this letter; and

 

	 	(h)	this letter constitutes
