redemption (the “Expiration Date”). The ordinary shares and Warrants comprising the Units represented by this certificate
are not transferable separately prior to the ninetieth (90th) day after the date of the prospectus relating to the
Company’s initial public offering, unless EarlyBirdCapital, Inc. determines that an earlier date is acceptable. The terms
