STOCK
ESCROW AGREEMENT


 


STOCK
ESCROW AGREEMENT, dated as of [_____], 2021 (“Agreement”), by and among AQUARIUS II ACQUISITION CORP., a Cayman Islands Company
(the “Company”), the initial shareholders listed on Exhibit A attached hereto (each, an “Initial Shareholder”
and collectively the “Initial Shareholders”) and AMERICAN STOCK TRANSFER & TRUST COMPANY, LLC, a New York limited liability
trust company (the “Escrow Agent”).


 


WHEREAS,
the Company has entered into an Underwriting Agreement, dated as of [*], 2021 (“Underwriting Agreement”), with and EF Hutton,
division of Benchmark Investments, LLC (“EF Hutton”), acting as the representative of the underwriters (collectively, the
“Underwriters”), pursuant to which, among other matters, the Underwriters have agreed to purchase 5,000,000 units (“Units”)
of the Company, plus an additional 750,000 Units if the Underwriters exercise their over-allotment option in full. Each Unit consists
of one ordinary share of the Company, $0.0001 par value (an “Ordinary Share”), and one-half of one redeemable warrant, each
whole redeemable warrant entitling its holder to purchase one Ordinary Share at an exercise price of $11.50 per full Ordinary Share,
all as more fully described in the Company’s final Prospectus, dated [______], 2021 (“Prospectus”), comprising part
of the Company’s Registration Statement on Form S-1 (File No. 333-[______]) under the Securities Act of 1933, as amended (“Registration
Statement”), declared effective on [______], 2021 (“Effective Date”).


 


WHEREAS,
the Initial Shareholders have agreed as a condition of the sale of the Units to deposit their Insider Shares (as defined in the Prospectus),
as set forth opposite their respective names in Exhibit A attached hereto (collectively “Escrow Shares”), in escrow as hereinafter
provided.


 


WHEREAS,
the Company and the Initial Shareholders desire that the Escrow Agent accept the Escrow Shares, in escrow, to be held and disbursed as
hereinafter provided.


 


IT
IS AGREED:


 


1.
Appointment of Escrow Agent. The Company and the Initial Shareholders hereby appoint the Escrow Agent to act in accordance with
and subject to the terms of this Agreement and the Escrow Agent hereby accepts such appointment and agrees to act in accordance with
and subject to such terms.


 


2.
Deposit of Escrow Shares. On or prior to the date hereof, each of the Initial Shareholders delivered to the Escrow Agent certificates
representing such Initial Shareholder’s respective Escrow Shares, together with applicable share powers, to be held and disbursed
subject to the terms and conditions of this Agreement. Each of the Initial Shareholders acknowledges that the certificate representing
such Initial Shareholder’s Escrow Shares is legended to reflect the deposit of such Escrow Shares under this Agreement.


 


3.
Disbursement of the Escrow Shares.


 


3.1
The Escrow Agent shall hold the Escrow Shares during the period (the “Escrow Period”) commencing on the date hereof and (i)
for 100% of the Escrow Shares, ending 150 calendar days after the date of the consummation of an initial Business Combination and the
date on which the closing price of our Ordinary Share equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends,
reorganizations and recapitalizations) for any 20 trading days within any 30-trading day period commencing after the closing of the Company’s
initial business Combination and (ii) six months after the date of the consummation of an initial Business Combination. The Company shall
promptly provide written notice of the consummation of a Business Combination to the Escrow Agent. Upon completion of the Escrow Period,
the Escrow Agent shall disburse such amount of each Initial Shareholder’s Escrow Shares (and any applicable share power) to such
Initial Shareholder; provided, however, that if the Escrow Agent is notified by the Company pursuant to Section 6.7 hereof that the Company
is being liquidated at any time during the Escrow Period, then the Escrow Agent shall promptly destroy the certificates representing
the Escrow Shares; provided further, however, that if, any time after the Company consummates a Business Combination, the Company (or
the surviving entity) subsequently consummates a liquidation, merger, stock exchange or other similar transaction which results in all
of the shareholders of such entity having the right to exchange their Ordinary Shares for cash, securities or other property, then the
Escrow Agent will, upon receipt of a written notice executed by the Chairman of the Board, Chief Executive Officer or other authorized
officer of the Company, in form reasonably acceptable to the Escrow Agent, certifying that such transaction is then being consummated
or such conditions have been achieved, as applicable, release the Escrow Shares to the Initial Shareholders. The Escrow Agent shall have
no further duties hereunder after the disbursement or destruction of the Escrow Shares in accordance with this Section 3.


 






    	 	 	 



     


    

 


3.2
Notwithstanding Section 3.1, if the Underwriters do not exercise their over-allotment option to purchase an additional 750,000 Units
of the Company in full within 45 days of the date of the Prospectus (as described in the Underwriting Agreement), the Initial Shareholders
agree that the Escrow Agent shall return to the Company for cancellation, at no cost, the number of Escrow Shares held by each such holder
determined by multiplying (a) the product of (i) 750,000 multiplied by (ii) a fraction, (x) the numerator of which is the number of Escrow
Shares held by each such holder, and (y) the denominator of which is the total number of Escrow Shares, by (b) a fraction, (i) the numerator
of which is 750,000 minus the number of Ordinary Shares purchased by the Underwriters upon the exercise of their over-allotment option,
and (ii) the denominator of which is 750,000. The Company shall promptly provide written notice to the Escrow Agent of the expiration
or termination of the Underwriters’ over-allotment option and the number of Units, if any, purchased by the Underwriters in connection
with their exercise thereof.


 


4.
Rights of Initial Shareholders in Escrow Shares.


 


4.1
Voting Rights as a Shareholder. Subject to the terms of the Insider Letters described in Section 4.4 hereof and except as herein
provided, the Initial Shareholders shall retain all of their rights as shareholders of the Company during the Escrow Period, including,
without limitation, the right to vote such shares.


 


4.2
Dividends and Other Distributions in Respect of the Escrow Shares. During the Escrow Period, all dividends payable in cash with
respect to the Escrow Shares shall be paid to the Initial Shareholders, but all dividends payable in shares or other non-cash property
(“Non-Cash Dividends”) shall be delivered to the Escrow Agent to hold in accordance with the terms hereof. As used herein,
the term “Escrow Shares” shall be deemed to include the Non-Cash Dividends distributed thereon, if any. 


 


4.3
Restrictions on Transfer. During the Escrow Period, the only permitted transfers of the Escrow Shares will be (i) to the Company’s
pre-IPO shareholders, or to the Company’s officers, directors, advisors and employees, (ii) if the Initial Shareholder is an entity,
as a distribution to partners, members or shareholders of the Initial Shareholder upon the liquidation and dissolution of the Initial
Shareholder, (iii) by bona fide gift to a member of the Initial Shareholder’s immediate family or to a trust, the beneficiary of
which is the Initial Shareholder or a member of the Initial Shareholder’s immediate family for estate planning purposes, (iv) by
virtue of the laws of descent and distribution upon death of the Initial Shareholder, (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 Private Units were originally purchased or (vii) to the Company for cancellation in accordance with Section 3.2 above or in
connection with the consummation of a Business Combination, in each case, except for clause (vii), on the condition that such transfers
may be implemented only upon the respective transferee’s written agreement to be bound by the terms and conditions of this Agreement
and of the Insider Letter (as defined below) signed by the Initial Shareholder transferring the Escrow Shares.


 


4.4
Insider Letters. Each of the Initial Shareholders has executed a letter agreement with EF Hutton and the Company, dated as indicated
on Exhibit A hereto, and the form of which is filed as an exhibit to the Registration Statement (“Insider Letter”), respecting
the rights and obligations of such Initial Shareholder in certain events, including but not limited to the liquidation of the Company.


 


5.
Concerning the Escrow Agent.


 


5.1
Good Faith Reliance. The Escrow Agent shall not be liable for any action taken or omitted by it in good faith and in the exercise
of its own best judgment, and 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 Escrow Agent), 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 Escrow Agent to be genuine and to be signed or presented by the proper person or persons.
The Escrow Agent shall not be bound by any notice or demand, or any waiver, modification, termination or rescission of this Agreement
unless evidenced by a writing delivered to the Escrow Agent signed by the proper party or parties and, if the duties or rights of the
Escrow Agent are affected, unless it shall have given its prior written consent thereto.

Agent hereunder, or the Escrow Shares held by it hereunder, other than expenses or losses arising from the gross negligence or willful
misconduct of the Escrow Agent. Promptly after the receipt by the Escrow Agent of notice of any demand or claim or the commencement of
any action, suit or proceeding, the Escrow Agent shall notify the other parties hereto in writing. In the event of the receipt of such
notice, the Escrow Agent, in its sole discretion, may commence an action in the nature of interpleader in an appropriate court to determine
ownership or disposition of the Escrow Shares or it may deposit the Escrow Shares with the clerk of any appropriate court or it may retain
the Escrow Shares pending receipt of a final, non-appealable order of a court having jurisdiction over all of the parties hereto directing

cause to be delivered to the Escrow Agent such further documents and instruments and shall do or cause to be done such further acts as

Escrow Agent may deposit the Escrow Shares with any court it reasonably deems appropriate.


 


5.6
