[1] Shares and the associated amounts have been retroactively restated to reflect: (i) the surrender of 2,875,000 Class B ordinary shares to the Company for cancellation for no consideration on December 16, 2020; and (ii) the share capitalization of 1,150,000 shares on January 6, 2021, resulting in an aggregate of 6,900,000 Class B ordinary shares outstanding (see Note 6).

[2] This number includes up to 900,000 Class B ordinary shares subject to forfeiture if the over-allotment option was not exercised in full or in part by the underwriter. On January 11, 2021, the underwriter exercised its over-allotment option, in full; thus these shares are no longer subject to forfeiture (see Note 6).
