The aggregate number of shares of Class A Common beneficially owned by the Reporting Persons constitutes approximately 4.2% of the shares of such class outstanding as of November 30, 2004.

As such, the group formed thereby would be deemed to beneficially own the aggregate of 24,293,898 shares of Class A Common held by such persons, which would represent 34.1% of the outstanding shares of Class A Common.

The filing of this Schedule 13D shall not be construed as an admission that the Reporting Persons (or any of their affiliates) is the beneficial owner of any such shares of Class A Common other than those disclosed in this Schedule 13D. Each of the Reporting Persons disclaim beneficial ownership of the shares of Class A Common held by the other stockholders party to the Securityholders’ Agreement that are not Reporting Persons hereunder.
