As more fully described in, and subject
to the terms and conditions described in, the Company’s final prospectus for its initial public offering, dated [                    ],
2021, the holder(s) of this certificate shall be entitled to receive a pro rata portion of certain funds held in the trust account
established in connection with the Company’s initial public offering only in the event that (i) the Company redeems the Class
A ordinary shares sold in its initial public offering and liquidates because it does not consummate an initial business combination
within the period of time set forth in the amended and restated memorandum and articles of association, (ii) the Company redeems
the Class A ordinary shares sold in its initial public offering in connection with a shareholder vote to amend the amended and
restated memorandum and articles of association (A) that would modify the substance or timing of the Company’s obligation
to provide holders of the Class A ordinary shares the right to have their shares redeemed in connection with the Company’s
initial business combination or to redeem 100% of the Class A ordinary shares if the Company does not complete its initial business
combination within the time period set forth therein or (B) with respect to any other provision relating to the rights of holders
of the Class A ordinary shares, or (iii) if the holder(s) seek(s) to redeem for cash his, her or its respective Class A ordinary
shares in connection with a tender offer (or proxy solicitation, solely in the event the Company seeks shareholder approval of
the proposed initial business combination) setting forth the details of a proposed initial business combination. In no other circumstances
shall the holder(s) have any right or interest of any kind in or to the trust account.
