FORM OF SPONSOR WARRANTS PURCHASE AGREEMENT 

THIS SPONSOR WARRANTS PURCHASE AGREEMENT, dated as of ______________, 2021 (as it may from time to time be amended, this
“Agreement”), is entered into by and between Black Spade Acquisition Co, a Cayman Islands exempted company (the “Company”), and Black Spade Sponsor LLC, a Cayman Islands limited liability company (the
“Purchaser”). 
 WHEREAS: 

The Company intends to consummate an initial public offering of the Company’s units (the “Public Offering”), each unit
consisting of one Class A ordinary share of the Company, par value $0.0001 per share (each, an “Ordinary Share”), and one-half of one redeemable warrant; 

Each whole warrant entitles the holder to purchase one Ordinary Share at an exercise price of $11.50 per Ordinary Share; and 

The Purchaser has agreed to purchase an aggregate of 7,000,000 warrants (or up to 7,600,000 warrants if the over-allotment option in
connection with the Public Offering is exercised in full) (the “Sponsor Warrants”), each Sponsor Warrant entitling the holder to purchase one Ordinary Share at an exercise price of $11.50 per Ordinary Share. 

NOW THEREFORE, in consideration of the mutual promises contained in this Agreement and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties to this Agreement hereby, intending legally to be bound, agree as follows:

Purchaser and the Company (the “Initial Closing Date”), the Company shall issue and sell to the Purchaser, and the Purchaser shall purchase from the Company, 7,000,000 Sponsor Warrants at a price of $1 per warrant for an aggregate
purchase price of $7,000,000 (the “Purchase Price”), which shall be paid by wire transfer of immediately available funds to the Company at least one day prior to the Initial Closing Date in accordance with the Company’s wiring

option in connection with the Public Offering or on such earlier time and date as may be mutually agreed by the Purchaser and the Company (each such date, an “Over-allotment Closing Date,” and each Over-allotment Closing Date (if
any) and the Initial Closing Date being sometimes referred to herein as a “Closing Date”), the Company shall issue and sell to the Purchaser, and the Purchaser shall purchase from the Company, up to an aggregate of 600,000
additional Sponsor Warrants, in the same proportion as the amount of the option that is then so exercised, at a price of $1 per warrant for an aggregate purchase price of up to $600,000 (if the over-allotment option in connection with the Public
Offering is exercised in full) (the “Over-allotment Purchase Price”), which shall be paid by wire transfer of immediately available funds to the Company at least one day prior to the Over-allotment Closing Date in accordance with
the Company’s wiring instructions. On the Over-allotment Closing Date, following the payment by the Purchaser of the Over-allotment Purchase Price by wire transfer of immediately available funds to the Company, the Company shall, at its option,

thereto, in connection with the Public Offering. 
 (ii) At the time of, or prior to, the closing of the Public Offering, the

of its affiliates, members, officers, directors or beneficial shareholders of 20% or more of its outstanding securities, has experienced a disqualifying event as enumerated pursuant to Rule 506(d) of Regulation D under the Securities Act of 1933, as
amended (the “Securities Act”). 
 Section 3. Representations and Warranties of the Purchaser. As a
material inducement to the Company to enter into this Agreement and issue and sell the Sponsor Warrants to the Purchaser, the Purchaser hereby represents and warrants to the Company (which representations and warranties shall survive each Closing
Date) that: 
 (a) Organization and Requisite Authority. The Purchaser possesses all requisite power and authority necessary to carry
out the transactions contemplated by this Agreement. 
 (b) Authorization; No Breach. 

(i) This Agreement constitutes a valid and binding obligation of the Purchaser, enforceable in accordance with its terms,
subject to bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general equitable principles (whether considered in a proceeding in
equity or law). 
 (ii) The execution and delivery by the Purchaser of this Agreement and the fulfillment of and compliance
with the terms hereof by the Purchaser does not and shall not as of each Closing Date conflict with or result in a breach by the Purchaser of the terms, conditions or provisions of any agreement, instrument, order, judgment or decree to which the
Purchaser is subject. 
 (c) Investment Representations. 

(i) The Purchaser is acquiring the Sponsor Warrants and, upon exercise of the Sponsor Warrants, the Ordinary Shares issuable
upon such exercise (collectively, the “Securities”), for the Purchaser’s own account, for investment purposes only and not with a view towards, or for resale in connection with, any public sale or distribution thereof. 

(ii) The Purchaser is an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D under the
Securities Act. 
 (iii) The Purchaser understands that the Securities are being offered and will be sold to it in reliance
on specific exemptions from the registration requirements of the United States federal and state securities laws and that the Company is relying upon the truth and accuracy of, and the Purchaser’s compliance with, the representations and
warranties of the Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of the Purchaser to acquire such Securities.

 (iv) The Purchaser has not entered into this Agreement as a result of any
general solicitation or general advertising within the meaning of Rule 502(c) under the Securities Act. 
 (v) The Purchaser
has been furnished with all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Securities which have been requested by the Purchaser. The Purchaser has been afforded the
opportunity to ask questions of the executive officers and directors of the Company. The Purchaser understands that its investment in the Securities involves a high degree of risk and it has sought such accounting, legal and tax advice as it has
considered necessary to make an informed investment decision with respect to the acquisition of the Securities. 
 (vi) The
Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the
Securities by the Purchaser nor have such authorities passed upon or endorsed the merits of the offering of the Securities. 

(vii) The Purchaser understands that: (a) the Securities have not been and are not being registered under the Securities
Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (1) in a registered transaction or (2) sold in reliance on an exemption therefrom; and (b) except as specifically set forth in the
Registration Rights Agreement, neither the Company nor any other person is under any obligation to register the Securities under the Securities Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder.
In this regard, the Purchaser understands that the Securities and Exchange Commission (the “SEC”) has taken the position that promoters or affiliates of a blank check company and their transferees, both before and after a Business
Combination, are deemed to be “underwriters” under the Securities Act when reselling the securities of a blank check company. Based on that position, Rule 144 adopted pursuant to the Securities Act would not be available for resale
transactions of the Securities despite technical compliance with the requirements of such Rule, and the Securities can be resold only through a registered offering or in reliance upon another exemption from the registration requirements of the
Securities Act. 
 (viii) The Purchaser has such knowledge and experience in financial and business matters, knows of the
high degree of risk associated with investments in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and risks of an investment in the Securities and is able to bear the economic risk of an
investment in the Securities in the amount contemplated hereunder for an indefinite period of time. The Purchaser has adequate means of providing for its current financial needs and contingencies and will have no current or anticipated future needs
for liquidity which would be jeopardized by the investment in the Securities. The Purchaser can afford a complete loss of its investment in the Securities.
