Each share of Class A common stock is entitled to one vote and each share of Class B common stock is entitled to ten votes. 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 holder and upon the occurrence of certain other events as described in the Issuer’s Amended and Restated Certificate of Incorporation. In addition, each share of Class B common stock will automatically convert into one share of Class A common stock upon any transfer, except for certain permitted transfers as described in the Issuer’s Amended and Restated Certificate of Incorporation.

The percentage reported assumes the exercise of all options held by the Reporting Person that are exercisable within 60 days of December 31, 2020 and the conversion of all of the Reporting Persons’ Class B common stock into Class A common stock, resulting in a total of 10,876,100 shares of the Issuer’s Class A common stock outstanding. The percentage reported is based on the total of 204,116,654 shares of common stock (which reflects the sum of (x) 193,334,764 shares of Class A common stock, and (y) 10,781,890 shares of Class B common stock) outstanding as of December 31, 2020.

The percentage reported does not reflect the ten for one voting power of the Class B common stock. The 10,814,472 shares of Class B common stock and 61,628 shares of Class A common stock held by the Reporting Person represent 33.6% of the aggregate combined voting power of the Class A common stock and Class B common stock as of December 31, 2019.
