WHEREAS, as of the date hereof, each Founder is the record owner of the number of shares of Acquiror Class B Common Stock as set forth opposite such Founder’s name on Exhibit A hereto (all such shares of Acquiror Class B Common Stock and any shares of Acquiror Class B Common Stock of which ownership of record or the power to vote is hereafter acquired by the Founders prior to the termination of this Agreement being referred to herein as the “Shares”).

NOW, THEREFORE, in consideration of the foregoing and of the mutual covenants and agreements contained herein, and intending to be legally bound hereby, each of the Founders (severally, and not jointly or jointly and severally) and the Acquiror hereby agree as follows:

1. Waiver of Anti-Dilution Provision. Subject to, and effective immediately prior to, the Closing, each Founder hereby irrevocably waives, to the fullest extent permitted by law and the Amended and Restated Certificate of Incorporation of Acquiror, dated November 24, 2020 (as it may be amended from time to time, the “Certificate of Incorporation”), any and all rights such Founder has or will have with respect to the adjustment to the initial conversion ratio provided by Section 4.3(b)(ii) of the Certificate of Incorporation. The waiver specified in this Section 1 shall be applicable only in connection with the transactions contemplated by the BCA and this Agreement and shall be void and of no force and effect if the BCA shall be terminated for any reason. Without limitation of the foregoing, upon the Closing, each Founder hereby acknowledges and agrees that, pursuant to Section 4.3(b) of the Certificate of Incorporation, each share of Class B Common Stock held by such Founder (for the avoidance of doubt, not including the shares of Class B Common Stock surrendered pursuant to Section 2) shall automatically convert into one share of Acquiror Class A Common Stock.

2. Contingent Sponsor Founder Share Cancellation.
