Explanation of Responses:

1. This Form 4 is filed by Jacob Ma-Weaver (the "Reporting Person"). The Reporting Person, the Funicular Fund (the "Fund") and Cable Car Capital LLC ("Cable Car") may be deemed to be a member of a Section 13(d) group that may be deemed to collectively beneficially own more than 10% of the Issuer's outstanding shares of Common Stock (the "Shares"). Each of the Reporting Person, the Fund and Cable Car disclaim beneficial ownership of the securities reported herein except to the extent of his or its pecuniary interest therein.

2. Represents securities directly owned by the Fund. Cable Car, as the general partner of the Fund, may be deemed to beneficially own the securities directly owned by the Fund. Mr. Ma-Weaver, as the Managing Member of Cable Car, may be deemed to beneficially own the securities directly owned by the Fund.

3. Grant to the Reporting Person of a stock option under the 2020 Equity Incentive Plan (the Plan), vesting in 36 equal monthly installments from the date of grant, provided that the Reporting Person's continuous service to the Issuer has not been terminated as defined in or as determined under the Plan prior to such time. In the event of a change in control of the Issuer, 50% of the unvested options shall become fully and immediately vested upon the closing date of such change in control, provided, however, that on the earlier of (i) the one-year anniversary of the closing date or (ii) involuntary termination, any options that remain unvested on such earlier date shall become fully and immediately vested.

4. Pursuant to the terms of the Plan, the stock option may not be transferred. Upon vesting, the Reporting Person intends on exercising the option and assigning the underlying shares to the Fund.
