In addition, each share of Class B Common Stock will convert automatically into one share of Class A Common Stock upon any transfer, whether or not for value, except for certain permitted transfers described in the Issuer's Amended and Restated Certificate of Incorporation.
(2) The Reporting Person is a newly formed limited liability company formed for the purpose of being the general partner of RKMP H Company LP, BKMP H Company LP and LCI H Company LP, which are newly formed limited partnerships formed for the purpose of receiving shares of Class B Common Stock from various trusts that are limited partners of those entities.
