How do I vote my shares?

If you are a holder of record of CBAH common stock as of the close of business on October 27, 2021, the record date for the special meeting, you may vote at the Special Meeting via the virtual meeting platform or by submitting a proxy for the special meeting in advance. You may submit your proxy by completing, signing, dating and returning the enclosed proxy card in the accompanying pre-addressed postage paid envelope.

If you hold your shares in “street name,” and do not receive a Voting Instruction Form or have any questions about this form, you should contact such broker, bank or nominee to ensure that votes related to the shares you beneficially own are properly counted. If you hold your shares “in street name” and you plan to attend and vote at the Special Meeting, then you will need to obtain a proxy from your broker, bank or nominee.
