Explanation of Responses:

1. The reported securities are owned directly by Sentinel Management Holdings, LLC (the "Sponsor"). CSL Sentinel Holdings, LLC ("CSL Sentinel") is the managing member of the Sponsor and the Reporting Person is the managing member of CSL Sentinel. The Reporting Person disclaims beneficial ownership of the reported securities except to the extent of his pecuniary interest therein, and the inclusion of these shares in this report shall not be deemed an admission that the Reporting Person is the beneficial owner of or has any pecuniary interest in, these securities for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, or for any other purpose.

2. If an initial business combination between the issuer and another company would have occurred prior to the expiration of the deadline in the issuer's charter, the shares of Class B Common Stock would have converted into shares of Class A Common Stock on a one-for-one basis, subject to adjustment pursuant to certain anti-dilution rights. The issuer did not consummate an initial business combination prior to the expiration of the deadline in the issuer's charter and the Sponsor forfeited 90% of its shares of Class B Common Stock in connection therewith. The shares of Class B Common Stock have no expiration date. Shares of Class B Common Stock were formerly known as Class B Ordinary Shares.
