Explanation of Responses:

1. As described in the registrant's registration statement on Form S-1 (File No. 333-252109) under the heading "Description of Securities--Founder Shares", the Class B common stock will automatically convert into Class A common stock at the time of the issuer's initial business combination, on a one-for-one basis, subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like, and certain anti-dilution rights and has no expiration date.

2. These shares represent Class B common stock held by TBCP III, LLC (the "Sponsor") acquired pursuant to a subscription agreement dated as of June 12, 2020 by and between the Sponsor and the registrant. Gary A. Simanson, the President and Chief Executive Officer of the registrant, is the managing member of the Sponsor. Mr. Simanson has sole voting and dispositive control over the shares held by the Sponsor and may be deemed the beneficial owner of such shares. These shares include an aggregate of 1,350,000 shares that are subject to forfeiture to the extent that the underwriter's do not exercise their overallotment option in connection with the registrant's initial public offering in full.

3. Mr. Simanson may be deemed to beneficially own shares held by the Sponsor by virtue of his control over the Sponsor, as its managing member. Mr. Simanson disclaims beneficial ownership of the common stock held by the Sponsor other than to the extent of his pecuniary interest in such shares.
