	 	Re:	Initial
    Public Offering


 


Gentlemen:


 


This
letter is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”)
entered into by and between Aquarius I Acquisition Corp., a Cayman Islands company (the “Company”), and Maxim
Group LLC, as Representative (the “Representative”) of the several underwriters named on Schedule A thereto
(the “Underwriters”), relating to an underwritten initial public offering (the “IPO”)
of the Company’s units (the “Units”), each comprised of one ordinary share of the Company, $0.0001 par
value each (the “Ordinary Shares”), one redeemable warrant, each warrant entitling its holder to purchase one-half
(1/2) of one Ordinary Share at an exercise price of $11.50 per full share (the “Warrants”), and one right to
receive one-tenth (1/10) of one Ordinary Share (the “Rights”). Certain capitalized terms used herein are defined
in paragraph 14 hereof.


 


In
order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the IPO, and in recognition
of the benefit that such IPO will confer upon the undersigned as a shareholder of the Company, and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the undersigned hereby agrees with the Company as follows:


 


1. If
the Company solicits approval of its shareholders of a Business Combination, the undersigned will vote all Ordinary Shares beneficially
owned by him, her or it, whether acquired before, in or after the IPO, in favor of such Business Combination.


 


2. (a)
Unless the Company’s shareholders are previously given the option to redeem their shares in connection with amending applicable
documents to extend the time that the Company has to complete a Business Combination and that the Company fails to consummate a Business
Combination within 12 months from the date that the registration statement is declared effective (or, in the event that the Company extended
the period of time to consummate a business combination up to three times, each by an additional three months, within 21 months) from
the date that the registration statement is declared effective, the undersigned shall take all reasonable steps to (i) cause the Trust
Fund to be liquidated and distributed to the holders of the IPO Shares and (ii) cause the Company to liquidate as soon as reasonably
practicable.


 


(b)
The undersigned hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust Fund and
any remaining net assets of the Company as a result of such liquidation with respect to his, her or its Insider Shares [including any
shares underlying the Private Units]1 (“Claim”) and hereby waives any Claim the undersigned may
have in the future as a result of, or arising out of, any contracts or agreements with the Company and will not seek recourse against
the Trust Fund for any reason whatsoever. [The undersigned acknowledges and agrees that there will be no distribution from the Trust
Fund with respect to any Warrants or Rights underlying the Private Units, all of which will terminate on the Company’s liquidation.]2


 


[(c)
In the event of the liquidation of the Trust Fund, the undersigned agrees to indemnify and hold harmless the Company against any and
all loss, liability, claims, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably
incurred in investigating, preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever) which
the Company may become subject as a result of any claim by any vendor or other person who is owed money by the Company for services rendered
or products sold or contracted for, but only to the extent necessary to ensure that such loss, liability, claim, damage or expense does
not reduce the amount of funds in the Trust Fund; provided, that such indemnity shall not apply if such vendor or other person has executed
an agreement waiving any claims against the Trust Fund.]3


 


	1	NTD:
    Only include for Aquarius Sponsor Limited.


 


	2	NTD:
    Only include for Aquarius Sponsor Limited.


 


	3	NTD:
    Only include for Aquarius Sponsor Limited.





 






    


     


    

 


3. [In
the event that the Company does not consummate a Business Combination and must liquidate and its remaining net assets are insufficient
to complete such liquidation, the undersigned agrees to advance such funds necessary to complete such liquidation and agrees not to seek
recourse for such expenses.]4


 


4. The
undersigned will escrow all of his, her or its Insider Shares pursuant to the terms of a Stock Escrow Agreement, which the Company will
enter into with the undersigned and an escrow agent acceptable to the Company.


 


5. [The
undersigned agrees that until the Company consummates a Business Combination, the undersigned’s Private Units will be subject to
the transfer restrictions described in the Subscription Agreement relating to the undersigned’s Private Units.]5


 


6. In
order to minimize potential conflicts of interest which may arise from multiple affiliations, the undersigned agrees to present to the
Company for its consideration, prior to presentation to any other person or entity, any suitable opportunity to acquire a target business,
until the earlier of the consummation by the Company of a Business Combination or the liquidation of the Company, subject to any pre-existing
fiduciary and contractual obligations the undersigned might have.


 


7. The
undersigned acknowledges and agrees that prior to entering into a Business Combination with a target business that is affiliated with
any Insiders of the Company or their affiliates, including any company that is a portfolio company of, or otherwise affiliated with,
or has received financial investment from, an entity with which any Insider or their affiliates is affiliated, such transaction must
be approved by a majority of the Company’s disinterested independent directors and the Company must obtain an opinion from an independent
investment banking firm that such Business Combination is fair to the Company’s unaffiliated shareholders from a financial point
of view.


 


8. Neither
the undersigned, any member of the family of the undersigned, nor any affiliate of the undersigned will be entitled to receive and will
not accept any compensation or other cash payment prior to, or for services rendered in connection with, the consummation of the Business
Combination; provided that the Company shall be allowed to repay working capital loans made by the undersigned to the Company
in cash upon consummation of the Business Combination. Notwithstanding the foregoing, the undersigned and any affiliate of the undersigned
shall be entitled to reimbursement from the Company for their out-of-pocket expenses incurred in connection with identifying, investigating
and consummating a Business Combination.


 


9. Neither
the undersigned, any member of the family of the undersigned, nor any affiliate of the undersigned will be entitled to receive or accept
a finder’s fee or any other compensation in the event the undersigned, any member of the family of the undersigned or any affiliate
of the undersigned originates a Business Combination.


 


10. [The
undersigned agrees to be a director/officer of the Company until the earlier of the consummation by the Company of a Business Combination
or the liquidation of the Company. The undersigned’s biographical information previously furnished to the Company and the Representative
is true and accurate in all material respects, does not omit any material information with respect to the undersigned’s biography
and contains all of the information required to be disclosed pursuant to Item 401 of Regulation S-K, promulgated under the Securities
Act of 1933.]6 The undersigned’s FINRA Questionnaire previously furnished to the Company and the Representative is true
and accurate in all material respects. The undersigned represents and warrants that:
