Explanation of Responses:

( 1 )Pursuant to the Agreement and Plan of Merger (the "Merger Agreement"), dated January 4, 2022, by and among the Issuer, Vera Whole Health, Inc. ("Vera Health"), and Carbon Merger Sub, Inc. (the "Merger Sub"), the Merger Sub merged with and into the Issuer (the "Merger"), with the Issuer surviving the Merger as a wholly owned subsidiary of Vera Health, effective as of February 17, 2022 (the "Effective Time"). Pursuant to the Merger Agreement, each share of the Issuer's Class A common stock and Class B common stock was exchanged for $2.05 in cash (the "Merger Consideration") at the Effective Time. ( 2 )The option is fully vested and exercisable. ( 3 )The option exercise price is equal to or exceeds the Merger Consideration and therefore the option was automatically cancelled without consideration immediately prior to the Effective Time.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
