The Issuer changed its name to Better Therapeutics, Inc. upon the Business Combination and BTX changed its name to Better Therapeutics OpCo, Inc. preceding the Business Combination. The foregoing description of the Business Combination does not purport to be complete and is qualified in its entirety by the full text of the Merger Agreement, which is attached as Exhibit 99.2 to this Statement and incorporated herein by reference.

Additionally, in connection with the Business Combination, on April 6, 2021, MCAD entered into subscription agreements (the “Subscription Agreements”), containing commitments to funding that were subject only to conditions that were generally aligned with the conditions set forth in the Merger Agreement, pursuant to which MCAD issued and sold to certain institutional and accredited investors (the “2021 PIPE Investors”), in a private placement that closed immediately prior to the closing of the Business Combination, 5,000,000 shares of Issuer Common Stock for a price of $10.00 per share for an aggregate commitment of $50,000,000 (the “2021 PIPE Investment”). The Perry Trust acquired 100,000 shares of Issuer Common Stock in the 2021 PIPE Investment at the closing of the Business Combination on the same terms and conditions as the other investors under the Subscription Agreements.

Pursuant to a stock purchase agreement by and among MCAD, Mountain Crest Capital LLC and the Perry Trust, Mountain Crest Capital LLC transferred 200,000 shares of Issuer Common Stock held by Mountain Crest Capital LLC to the Perry Trust upon the closing of the Business Combination for an aggregate of $1,800,000.
