### Footnotes:

(1) The sales reported on this Form 4 represent shares required to be sold by the Reporting Person to cover tax withholding obligations in connection with the vesting and settlement of restricted stock units. These sales are mandated by the Issuer's election under its equity incentive plans to require the satisfaction of tax withholding obligations to be funded by a "sell to cover" transaction and do not represent discretionary trades by the Reporting Person.

(2) The price reported is a weighted average price. These shares were sold in multiple transactions at prices ranging from $7.486 to $7.509, inclusive. The Reporting Person undertakes to provide to the Issuer, any security holder of the Issuer, or the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the ranges set forth herein.

(3) Includes 1,293 shares of Class of A Common Stock previously acquired under the Issuer's Employee Stock Purchase Plan on November 18, 2022. On each of September 1, 2022, October 3, 2022, November 1, 2022, December 5, 2022 and January 5, 2023, the Reporting Person's Form 4 filings reported, but did not reflect the acquisition of 3,000 shares of Class A Common Stock upon the conversion of shares of Class B Common Stock into shares of Class A Common Stock on a one-to-one basis in the amount of securities beneficially owned, and this Form 4 also corrects the related mathematical errors carried forward in subsequent reports.

(4) The sales reported were effected pursuant to a Rule 10b5-1 trading plan adopted by the Reporting Person.

(5) The price reported is a weighted average price. These shares were sold in multiple transactions at prices ranging from $6.85 to $7.22, inclusive. The Reporting Person undertakes to provide to the Issuer, any security holder of the Issuer, or the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the ranges set forth herein.

(6) The options are subject to a service-based vesting requirement, which shall be satisfied over a four-year period. 25% of the options vested on March 1, 2021 and 1/48th of the options vest monthly thereafter, subject to the Reporting Person's continuous service with the issuer. The options are exercisable into shares of Class B Common Stock, which are convertible on a one-to-one basis into shares of Class A Common Stock at the option of the holder.

(7) Each share of Class B Common Stock is convertible into one share of Class A Common Stock at any time at the option of the Reporting Person and has no expiration date.
