(SCP MF), Sylebra Capital Parc Master Fund (PARC MF), Sylebra Capital Menlo Master Fund (MENLO MF), and other advisory clients.

Sylebra Capital Management (Sylebra Cayman) is the investment manager and parent of Sylebra HK.

Gibson is a founder and Chief Investment Officer of Sylebra Cayman. In such capacities, Sylebra HK, Sylebra US, Sylebra Cayman and Gibson may be deemed to share voting and dispositive power over the securities of the Issuer held by the Affiliated Investment Entities.
(2) These securities are held by the Affiliated Investment Entities. Sylebra HK, Sylebra US, Sylebra Cayman, and Gibson disclaim beneficial ownership of these securities, and this report shall not be deemed an admission that Sylebra HK, Sylebra US, Sylebra Cayman, and Gibson are the beneficial owners of such securities, except to the extent of their pecuniary interest, if any, therein.
(3) The warrants are immediately exercisable; however, the warrants are subject to a 19.9% stock ownership cap. As a result, the warrants are not exercisable by the Affiliated Investment Entities at any time within 60 days of the issue date.
