(1)	This Form 4 reflects the surrender to the issuer of 127,174 of the issuer's Class B ordinary shares, par value $0.0001 per share, for no consideration by the reporting person as a result of its participation in the issuer's initial public offering, as more fully described in the issuer's registration statement on Form S-1 (File No. 333-252730).
(2)	As described in the issuer's registration statement on Form S-1 (File No. 333-252730) under the heading "Description of Securities -- Founder Shares", the Class B ordinary shares will automatically convert into Class A ordinary shares, par value $0.0001 per share, of the issuer at the time of the issuer's initial business combination, or earlier at the option of the holder, on a one-for-one basis, subject to adjustment for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like, and certain anti-dilution rights and have no expiration date.
(3)	This Form 4 is being filed by the reporting person. The reporting person is controlled by Daniel R. Revers.
