 the Proposed Public Offering, or $2,400,000 (or
$2,760,000 if the over-allotment option is exercised in full), or the amount remaining in the Trust Account following all properly submitted
shareholder redemption in connection with the consummation of the initial Business Combination, payable to the underwriters as deferred
underwriting discounts and commissions upon the consummation of the initial Business Combination. Except as described in this prospectus,
the funds held in trust will not be released until the earlier of the consummation of our initial business combination or our redemption
of the ordinary shares sold in this offering upon our failure to consummate a business combination within the required period.

Because our Sponsor acquired the founder shares
at a nominal price, our public shareholders will incur an immediate and substantial dilution upon the closing of this offering. See the section titled “Risk Factors — Risks Relating to our Securities — “The value of the founder shares following completion of our initial business combination is likely to be substantially higher than the nominal price paid for them, even if the trading price of our ordinary shares at such time is substantially less than $10.00 per public share .”

The following table illustrates our net tangible book value per share at the specified redemption levels. See the sections titled “Prospectus Summary – Dilution” and “Dilution” for more information.
