 name and you plan to vote your shares in virtually at the Special Meeting, you should contact your broker or agent to obtain a legal proxy or broker’s proxy card and bring it to the Special Meeting in order to vote.

How does our board of directors recommend that I vote on the proposal?

Our board of directors recommends that you vote “FOR” the approval of a resolution approving an amendment to our 2021 Incentive Equity Plan to increase the share pool for equity incentive grants under the plan.

If any other matter is presented at the Special Meeting, your proxy provides that your shares will be voted by the proxy holder listed in the proxy in accordance with the proxy holder’s judgment. At the time this proxy statement was first made available, we knew of no matters that needed to be acted on at the Special Meeting, other than those discussed in this proxy statement.

#### May I change or revoke my proxy?
If you give us your proxy, you may change or revoke it at any time before the Special Meeting. In addition to any method permitted under applicable law, you may change or revoke your proxy in any one of the following ways:

•

if you received a proxy card, by signing a new proxy card with a date later than your previously delivered proxy and submitting it as instructed above;

•

by re-voting by Internet as instructed above;

•

by notifying the Company’s Secretary in writing before the Special Meeting that you have revoked your proxy; or

•

by attending the Special Meeting virtually and voting at the meeting. Attending the Special Meeting will not in and of itself revoke a previously submitted proxy. You must specifically request at the Special Meeting that it be revoked.

Your most current vote, whether by Internet or proxy card is the one that will be counted.

Can I appoint some other person to be my proxyholder?

Every holder of common shares has the right to appoint some other person or company of their choice, who need not be a security holder, to attend and act on their behalf at the Special Meeting or any adjournment or postponement thereof. If you wish to appoint a person or company other than Gerard Barron and Craig Shesky or their substitute, please deliver a proxy in the form contemplated in the Articles
