Explanation of Responses:
(1)	Pursuant to the Agreement and Plan of Merger, dated April 6, 2021, as amended (the "Merger Agreement"), by and among Mountain Crest Acquisition Corp. II ("Issuer"), MCAD Merger Sub Inc. ("Merger Sub") and Better Therapeutics, Inc. ("BTX"), on October 28, 2021, Merger Sub merged with and into BTX, with BTX surviving the merger as a wholly-owned subsidiary of Issuer (such merger and the other transactions contemplated by the Merger Agreement, the "Business Combination").
(2)	At the effective time of the Business Combination ("Effective Time"), each BTX stock option was converted to a stock option to purchase the number of shares of Issuer common stock (the "Assumed Option") equal to the product of (i) the number of shares of BTX common stock subject to the BTX stock option and (ii) 0.9475 (the "Exchange Ratio"), and the exercise price per share of the Assumed Option (rounded up to the nearest whole cent) shall be equal to the quotient obtained by dividing (i) the exercise price per share of the BTX stock option by (ii) the Exchange Ratio. Each Assumed Option will continue to be subject to the terms and conditions set forth in the BTX 2020 Stock Option and Grant Plan, as amended. Issuer subsequently changed its name to Better Therapeutics, Inc.
(3)	The Assumed Option vests as to 1/4th of the shares subject to the Assumed Option on July 27, 2021 and the remaining shares vest in 36 equal monthly installments thereafter, provided the Reporting Person continues to have a service relationship with Issuer on each vesting date. The Assumed Option was granted on August 14, 2020.
(4)	Following the Issuer's filing of Form S-8 to register the shares subject to the Assumed Option, the Assumed Option shall vest in equal monthly installments over 48 months after April 6, 2021, provided the Reporting Person continues to have a service relationship with Issuer on each vesting date. The Assumed Option was granted on April 6, 2021.
