                         	  	Units.

 Each Unit (“Unit”) consists of one (1) Class A ordinary share, par value $0.0001 per share
(“Class A ordinary shares”), of Black Spade Acquisition Co, a Cayman Islands exempted company (the “Company”), and one-half
(1/2) of one redeemable warrant (each whole warrant, a “Warrant”). Each Warrant entitles the holder to purchase one (1) Class A ordinary share (subject to adjustment) for $11.50 per share (subject to adjustment).
Only whole Warrants are exercisable. Each Warrant will become exercisable on the later of (i) thirty (30) days after the Company’s completion of a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or
other similar business combination with one or more businesses (each a “Business Combination”), and (ii) twelve (12) months from the closing of the Company’s initial public offering, and will expire unless exercised
before 5:00 p.m., New York City Time, on the date that is five (5) years after the date on which the Company completes its initial Business Combination, or earlier upon redemption or liquidation. The Class A ordinary shares and Warrants
comprising the Units represented by this certificate will begin separate trading on the 52nd day following the date of the prospectus that is filed in connection with the offering of the Units (or, if such date is not a business day, the following
business day) unless Citigroup Global Markets Inc. elects to allow earlier separate trading, subject to the Company’s filing of a Current Report on Form 8-K with the Securities and Exchange Commission
containing an audited balance sheet reflecting the Company’s receipt of the gross proceeds of its initial public offering and issuing a press release announcing when separate trading will begin. No fractional Warrants will be issued upon
separation of the Units. The terms of the Warrants are governed by a Warrant Agreement, dated as of [•], 2021, between the Company and Continental Stock Transfer & Trust Company, as 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 the Warrant Agent at One State Street, 30th Floor, New York, New York 10004, and are available to any Warrant holder on written request and without cost. 

Upon the consummation of the Business Combination, the Units represented by this certificate will automatically separate into the Class A Ordinary Shares
and Warrants comprising such Units. 
 This certificate is not valid unless countersigned by the Transfer Agent and registered by Registrar
of the Company. 
 This certificate shall be governed by and construed in accordance with the internal laws of the State of New York. 

Witness the facsimile signatures of its duly authorized officers.
