Explanation of Responses:

1. These shares are held directly by a trust for the benefit of a minor child of the Reporting Person, for which the Reporting Person serves as co-trustee.

2. This Form 4 is being filed as promptly as practicable following a determination that the shares purchased for each of the trusts for the minor children may be attributable to the Reporting Person for purposes of Section 16 of the Securities Exchange Act of 1934. For purposes of the short-swing profit recovery provisions of Section 16(b) of the Securities Exchange Act of 1934, the indirect acquisition of these shares may be matchable with a sale of 25,000 shares by Altos Ventures Management Inc. (AVM) on August 31, 2021. The Reporting Person has paid to the Issuer an aggregate of $907.08 which represents the full amount of the profit realized in connection with the short-swing transactions by the childrens' trust accounts, without giving effect to direct transaction costs.

3. The Reporting Person serves as a member of the Board of Directors of AVM, and may be deemed to exercise voting and investment control over the shares held by AVM. The Reporting Person disclaims beneficial ownership of the shares held by AVM except to the extent of his pecuniary interest therein.
