### Footnotes:

(1) As described in the Issuer's registration statement on Form S-1 (File No. 333-291904) (the "Registration Statement") under the heading "Summary--Sponsor Information", the Class B ordinary shares will automatically convert into Class A ordinary shares 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 certain adjustments described therein and have no expiration date.

(2) 439,233 Class B ordinary shares were forfeited by United Acquisition SPAC LLC (the "Sponsor") to the Issuer at no cost in connection with the expiration of the remaining portion of the underwriters' over-allotment option, as described in the Registration Statement.

(3) These Class B ordinary shares are held by the Sponsor and were acquired pursuant to a subscription agreement by and between the Sponsor and the Issuer. Mr. Paul Packer, the Issuer's Chairman, Chief Executive Officer and Chief Financial Officer, is the sole managing member of the Sponsor. As a result, Mr. Packer may be deemed to have beneficial ownership of the Class B ordinary shares and the Private Placement Units (including the Private Placement Shares included in such units) held by the Sponsor. Mr. Packer disclaims such beneficial ownership except to the extent of his pecuniary interest therein.
