Explanation of Responses:

Id	Content
F1	Shares held by SBH Trust dated March 10, 2020, of which Reporting Person is Trustee.
F2	The Reporting Person filed a Form 4 on September 6, 2023 that incorrectly reported the number of shares of Class A and Class B common stock held by the SBH Trust dated March 10, 2023. The amount reported in Column 5 of Table I and Column 9 of Table II represents the number of Class A shares and Class B shares, respectively, held by the SBH Trust as of the date hereof.
F3	Each share of Class B Common Stock is convertible at any time at the option of the Reporting Person into one share of Class A Common Stock and has no expiration date. Each share of Class B Common Stock will convert automatically into one share of Class A Common Stock in connection with: (i) any transfer, whether or not for value, except for certain permitted transfers further described in the Issuer's amended and restated certificate of incorporation, (ii) such time as the aggregate number of shares of Class B Common Stock outstanding ceases to represent 5% of the aggregate number of shares of Common Stock outstanding, and (iii) the death of the Reporting Person.
