Explanation of Responses:

( 1 )This amount includes 4,487 shares deliverable upon vesting and settlement of restricted stock units. ( 2 )The reporting person beneficially owns these shares indirectly through the revocable Corsa Family Trust of 2006 (the "Trust"). The reporting person and his wife serve as the trustees and are the beneficiaries of the Trust. ( 3 )Pursuant to a rollover agreement entered into between the reporting person and Ambience Parent, Inc. ("Parent") in connection with the effectuation of the transactions contemplated by the amended and restated merger agreement between the issuer, Parent, and Ambience Merger Sub, Inc. (the "Merger Agreement"), the reporting person exchanged these shares for shares of Parent having an equivalent value as of the effective date of the merger, based on a market value of the issuer shares on the effective date of $37 per share. ( 4 )This amount consists of shares deliverable upon vesting and settlement of restricted stock units. ( 5 )These restricted stock units were cancelled pursuant to the Merger Agreement in exchange for a cash payment equal to the market value of the underlying issuer common stock on the effective date of the merger ($37 per share). ( 6 )This option was fully vested and exercisable as of the cancellation date. ( 7 )This option was cancelled pursuant to the Merger Agreement in exchange for a cash payment equal to, for each share subject to the option, the amount by which the market value of the underlying issuer common stock on the effective date of the merger ($37 per share) exceeded the per share exercise price of the option. ( 8 )This option was vested with respect to 106,402 shares and provided for vesting of the remainder of the option on April 3, 2022. ( 9 )This option was vested with respect to 58,264 shares and provided for vesting of the remainder of the option on March 28, 2022. ( 10 )This option was scheduled to fully vest on January 29, 2022. ( 11 )This option was vested with respect to 76,667 shares and provided for vesting of the remainder of the option in substantially equal annual installments on each of June 22, 2022 and June 22, 2023. ( 12 )The portion of this option that was vested or scheduled to vest on or before July 23, 2022 was cancelled pursuant to the Merger Agreement in exchange for a cash payment equal to, for each share subject to the option, the amount by which the market value of the underlying issuer common stock on the effective date of the merger ($37 per share) exceeded the per share exercise price of the option. The portion of this option scheduled to vest after July 23, 2022 was cancelled pursuant to the Merger Agreement in exchange for a deferred cash payment (or, at the election of the reporting person, a grant of Parent restricted stock or restricted stock units having a grant date value) equal to the amount by which the market value of the underlying issuer common stock on the effective date of the merger ($37 per share) exceeded the exercise price of the option, subject to vesting on the same schedule as the cancelled option. ( 13 )This option provided for vesting in three substantially equal annual installments beginning on March 30, 2022.
