Explanation of Responses:
1. Represents a bona fide gift by the Reporting Person, for no consideration, to a trust established for the benefit of members of the Reporting Person's immediate family. 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"). The shares were transferred by the Reporting Person to the trust as a bona fide gift not involving a disposition for value, which is a permissible exception under the terms of the lock-up agreement. 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.
2. These shares are held by the Bluhm Joint Revocable Trust, a trust for the benefit of members of the Reporting Person's immediate family, of which the Reporting Person and his spouse serve as the trustees. By virtue of his relationship with the beneficiaries of the trust, the Reporting Person is deemed to have an indirect beneficial interest in the shares held by the trust. The Reporting Person disclaims beneficial ownership of these shares, except to the extent of any pecuniary interest therein.
