The Reporting Person is subject to a lock-up agreement that was entered into with the representatives of the underwriters in connection with an underwritten public offering of the Issuer's Class A Common Stock (the "Offering").

In connection with the gift, the trustee of the trust has executed and delivered to the representatives of the underwriters a lock-up agreement in substantially the form entered into by the Reporting Person in connection with the Offering, and the shares held by the trust remain subject to the restrictions on transfer set forth therein for the balance of the applicable lock-up period.↩ 1↩ 2
