(the “Registrant”). The description of the units, Class A ordinary shares and warrants set forth under the heading “Description of Securities” in the Registrant’s prospectus forming part of its Registration Statement on Form S-1 (File No. 333-249853), originally filed with the U.S. Securities and Exchange Commission on November 4, 2020, as thereafter amended and supplemented from time to time (the “Registration Statement”), to which this Form 8-A relates is incorporated by reference herein. Any form of prospectus or prospectus supplement to the Registration Statement that includes such descriptions and that is subsequently filed is hereby also incorporated by reference herein.

Item 2. Exhibits

Pursuant to the Instructions as to Exhibits for Form 8-A, no exhibits are required to be filed, because no other securities of the Registrant are registered on The New York Stock Exchange, and the securities registered hereby are not being registered pursuant to Section 12(g) of the Securities Exchange Act of 1934, as amended.

SIGNATURE

Pursuant to the requirements of Section 12 of the Securities Exchange Act of 1934, as amended, the Registrant has duly caused this registration statement to be signed on its behalf by the undersigned, thereto duly authorized.
