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, each share of BTX common stock (including shares of BTX common stock resulting from the conversion of BTX preferred stock and BTX Simple Agreements for Future Equity) was converted into a right to receive the number of shares of Issuer common stock equal to the product of the number of shares of BTX common stock and 0.9475, with fractional shares rounded to the nearest whole share. Issuer subsequently changed its name to Better Therapeutics, Inc.
(3)	Following the Issuer's filing of Form S-8 to register the shares subject to the stock option, the stock option vests as to 1/4 of the shares subject to the stock option on May 10, 2022 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 stock option was granted on October 28, 2021.
