F1 On August 15, 2022, the reporting person exercised, by net exercise, a previously issued stock option to purchase 37,500 shares of Class A Common Stock of the Issuer. The reporting person paid the exercise price on a cashless basis, resulting in the Issuer withholding 963 shares of Class A Common Stock for payment of the exercise price, based on the closing price of the Issuer's Class A Common Stock on August 12, 2022 of $19.49, and issuing to the reporting person the remaining 36,537 shares of Class A Common Stock.
F2 The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $19.03 to $19.60, inclusive. The reporting person undertakes to provide to the Issuer, any security holder of the Issuer, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the ranges set forth in footnote (2) to this Form 4.
