(1)	Southern Cross Acquisition I Sponsor Corp., a Cayman Islands exempted company (the "Sponsor"), is the record holder of the securities reported herein.

(2)	Represents 15,000 ordinary shares included in 15,000 additional private units (the "Private Units") purchased by the Sponsor in a private placement (the "Private Placement") simultaneously with the closing of the Issuer's initial public offering in connection with the underwriter's exercise of their over-allotment option, at a purchase price of $10 per Private Unit. Each Private Unit consists of one ordinary share, one redeemable warrant, and one right to receive one-fourth (1/4) of one ordinary share.
