Explanation of Responses:

( 1 )As described in the Issuer's registration statement on Form S-1 (File No. 333-234324) under the heading "Description of Securities--Founder Shares", the shares of Class B Common Stock will automatically convert into shares of Class A Common Stock at the time of the Issuer's initial business combination on a one-for-one basis, subject to certain adjustment described therein and have no expiration date. ( 2 )On September 24, 2021, Amplitude Healthcare Acquisition Corporation ("AMHC" and the former name of the Issuer) consummated its business combination with Jasper Therapeutics, Inc. (the former name of Jasper Tx Corp.). In connection with the business combination, each share of Class B Common Stock converted to one share of Voting Common Stock. The reporting person resigned as a director and as an officer of the Issuer upon consummation of the business combination. ( 3 )Pursuant to an agreement by and between the Issuer and Amplitude Healthcare Holdings LLC, concurrent with the consummation of the business combination, these shares of Class B Common Stock were forfeited to the Issuer as of immediately prior to the Merger.
