### Footnotes:

(1) The Convertible Common Stock is convertible into a number of shares of Class B Common Stock (or Class A Common Stock if no Class B Common Stock is outstanding at the time of such conversion) representing the product of (i) 1.25% of the Issuer's fully diluted capital stock (including Class B or Class A Common Stock issuable upon such conversion) outstanding at the time of conversion multiplied by (ii) (A) two times (B) the value of one minus the quotient obtained by dividing (x) $28 (the "IPO Price") by (y) the stock price per Class A common stock at the time of conversion, subject to certain adjustments. The Convertible Common Stock will be convertible at the holder's option from April 17, 2031 until April 17, 2036; provided that prior to conversion, the price of Class A common stock must equal at least two-times the IPO Price.
