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 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 Company’s amended and restated memorandum and articles of association (as the same may be further amended, supplemented
or otherwise modified from time to time, the “amended and restated memorandum and articles of association”),
(ii) the Company redeems the 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 Ordinary Shares the right to have their shares redeemed in connection with the Company’s initial business
combination or to redeem 100% of the 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 Ordinary Shares, or (iii)
if the holder(s) seek(s) to redeem for cash his, her or its respective 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.
