Each Unit (“Unit”) consists
of one ordinary share, par value $0.001 per share, of Ace Global Business Acquisition
Limited, a British Virgin Islands company (the “Company”) and one redeemable warrant (“Warrant”). Each
redeemable Warrant entitles the holder thereof to purchase one ordinary share at a price of $11.50 per full 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) 12 from the date that the registration statement is declared effective. The ordinary shares and Warrants comprising the
Units represented by this certificate are not transferable separately prior to the 52nd day after the date of the prospectus relating
to the Company’s initial public offering, unless Ladenburg Thalmann & Co. Inc. (“Ladenburg”) as the representative
of the underwriters, determines that an earlier date is acceptable, but in no event will the ordinary shares 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 and Warrant prior to the 52nd day after the date of the prospectus.


 


The terms of the Warrants are governed
by a warrant agreement (the “Warrant Agreement”), dated as of [●], 2021, between the Company and Continental
Stock Transfer & Trust Company, as the warrant 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. Copies of the Warrant Agreement are
on file at the office of Continental Stock Transfer & Trust Company at 6201 15th Avenue, Brooklyn, New York, NY 11219, and
