UNITS CONSISTING OF ONE ORDINARY SHARE, ONE WARRANT AND
ONE RIGHT TO RECEIVE ONE-TENTH OF ONE ORDINARY SHARE

Each Unit (“Unit”) consists of one ordinary share, with a par value $0.0001 per share, of Aquarius I Acquisition Corp., a Cayman Islands company (the “Company”), one redeemable warrant (“Warrant”), and one right (“Right”) to receive one-tenth (1/10) of an ordinary share. Each redeemable Warrant entitles the holder thereof to purchase one ordinary share at a price of $11.50 per share (subject to adjustment), upon the later to occur of (i) the Company’s completion of a merger, share exchange, asset acquisition, share purchase, recapitalization, reorganization or other similar business combination with one or more businesses or entities (a “Business Combination”) or (ii) 9 months from the date that the registration statement is declared effective by the Securities and Exchange Commission (or up to 18 months from the date that the registration statement is declared effective if we extend the period of time to consummate a business combination). Every ten Rights entitles the holder thereof to receive one ordinary share upon consummation of the Company’s initial Business Combination. The ordinary shares, Rights and Warrants comprising the Units represented by this certificate are not transferable separately prior to the 52nd business day after the date of the prospectus relating to the Company’s initial public offering, unless Maxim Group LLC (“Maxim”) as the representative of the underwriters, determines that an earlier date is acceptable, but in no event will the ordinary shares, Rights and Warrants be traded separately until the Company files with the Securities and Exchange Commission (the “SEC”) a current report on Form 8-K which includes an audited balance sheet reflecting the receipt by the Company of the gross proceeds from its initial public offering including the proceeds received by the Company from the exercise of the over-allotment option thereto, if the over-allotment option is exercised. If the over-allotment option is exercised after the date of the prospectus, we will file an amendment to the Form 8-K or a new Form 8-K to provide updated financial information to reflect the exercise of the over-allotment option. We will also include in the Form 8-K, or amendment thereto, or in a subsequent Form 8-K, information indicating if the underwriters has allowed separate trading of the ordinary shares, Rights and Warrant prior to the 52nd business day after the date of the prospectus.

The terms of the Warrants and Rights are governed by a warrant agreement (the “Warrant Agreement”), dated as of [●], 2022, and a rights agreement (the “Rights Agreement”), dated as of [●], 2022, respectively, both between the Company and American Stock Transfer & Trust Company, LLC as the warrant agent and rights agent, and are subject to the terms and provisions contained therein, all of which terms and provisions the holder of this certificate consents to by acceptance hereof.
