 of $5,000,001, are redeemed.                                                               |

For purposes of presentation,
we have reduced our pro forma net tangible book value after this offering by $45,505,471 (or $53,005,471 if the underwriters’ over-allotment option
is exercised in full), assuming a maximum redemption that would permit us to maintain net tangible assets of $5,000,001, because
holders of our public shares may redeem their shares for a pro rata share of the aggregate amount then on deposit in the trust account
at a per share redemption price equal to the amount in the trust account as set forth in our tender offer or proxy materials (initially
anticipated to be the aggregate amount held in trust two business days prior to the commencement of our tender offer or shareholders
meeting, including interest, divided by the number of Class A ordinary shares sold in this offering). The actual redemption value that
may be redeemed could exceed this amount provided that our net tangible assets are greater than $5,000,001 either immediately prior to
or upon consummation of our initial business combination.

For each of the redemption scenarios above, the NTBV was calculated as follows:
