Explanation of Responses:

( 1 )As previously disclosed, 3,074,653 shares of Common Stock of the Issuer, par value $0.001 ("Common Stock") were indirectly held by Mr. Egeck and directly held by Bubbles Holdings, L.P. Such shares of Common Stock were distributed to Mr. Egeck as soon as reasonably practicable after the date of the Issuer's initial public offering and are now held directly by Mr. Egeck as reported herein. Due to an administrative error, the Form 3 filed on October 28, 2020 overstated Mr. Egeck's indirect holdings by 22 shares. ( 2 )Represents shares of Common Stock sold to satisfy tax liability upon settlement of restricted stock units ("RSUs"). ( 3 )Each RSU represents the contingent right to receive, upon vesting of the RSU, one share of the Issuer's Common Stock. ( 4 )Represents a grant of RSUs, of which 205,545 vested and of which the remaining 2,329,519, subject to Mr. Egeck's continuous employment or service with the Issuer or an affiliate until the applicable vesting date: (a) 1,233,276 of the remaining RSUs will vest in equal installments of 205,545 on August 4, 2021 and each of the five (5) six (6)-month anniversaries thereafter; and (b) 1,096,243 of the remaining RSUs will vest if, and only if, the volume weighted average trading price of a share of the Issuer's Common Stock equals $10.71 at the end of any rolling twenty (20)-day trading period commencing on or after May 2, 2021.
