(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, a “Share”), and one-half of one redeemable warrant, each whole warrant entitling the holder to purchase one Share at an exercise price of $11.50 per Share, as set forth in the Company’s Registration Statement on Form S-1, filed with the U.S. Securities and Exchange Commission (the “SEC”), File Number 333-259532 under the Securities Act of 1933, as amended (the “Securities Act”).

WHEREAS, the Purchaser has agreed to purchase an aggregate of 700,000 warrants (and up to 105,000 additional redeemable warrants if the underwriter in the Public Offering exercises its option to purchase additional units in full) (the “Private Placement Warrants”), at a price of $1.25 per Private Placement Warrant, subject to adjustment, each Private Placement Warrant entitling the holder to purchase one Share at an exercise price of $11.50 per 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:

(iv) The Purchaser did not decide to enter 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 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 investments in the Securities.
