The Class A Shares carry one vote per share and the Class B Shares carry five votes per share. As of the close of business on April 8, 2002, each of VII, VI, NAIRI, NAI and Mr. Sumner M. Redstone beneficially owned one hundred forty-four million thirty- three thousand six hundred (144,033,600) Class A Shares, comprised of (i) thirty-three thousand six hundred (33,600) Class A Shares, and (ii) one hundred forty-four million (144,000,000) Class B Shares convertible into Class A Shares on a one-for-one basis; representing approximately 80.9% of the Issuer's Class A Shares (based upon 178,019,354 Common Shares that were reported by the Issuer to be issued and outstanding as of March 8, 2002, and assuming conversion in full of the Class B Shares into Class A Shares).
