** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Acquired pursuant to a merger between the former Viacom Inc. (now known as CBS Corporation) and Viacom Merger Sub Inc. (the Merger), in which each share of Viacom Class B common stock was exchanged for 0.5 shares of CBS Corporation Class B common stock and 0.5 shares of the Issuer's Class B common stock, with fractional shares paid in cash. On January 3, 2006, the first business day following the effective time of the Merger, the opening price of the Issuer's Class B common stock on the New York Stock Exchange was $41.12 per share. The Issuer changed its name from New Viacom Corp. to Viacom Inc. upon completion of the Merger.
(2) Right to buy under the Viacom Inc. 2006 Stock Option Plan for Outside Directors.
(3) Current.
(4) In the Merger, each grant of stock options to purchase Viacom Class B common stock was converted into a number of stock options to purchase the Issuer's Class B common stock determined by multiplying the number of outstanding stock options included in the grant before the Merger by 0.792802. The per share exercise price of the converted stock option was determined by dividing the pre-Merger exercise price by 0.792802.
(5) These options vest annually in three equal installments beginning on January 31, 2005.
(6) These options vest annually in three equal installments beginning on January 31, 2006.
(7) Granted under the Viacom Inc. 2006 RSU Plan for Outside Directors.
(8) Each Restricted Share Unit is the economic equivalent of one share of the Issuer's Class B common stock. The Restricted Share Units will vest on May 26, 2006 and will be settled by delivery of a corresponding number of shares upon vesting, unless the Reporting Person has elected to defer settlement.
(9) In the Merger, each grant of Restricted Share Units of Viacom Class B common stock was converted into a number of Restricted Share Units of the Issuer's Class B common stock determined by multiplying the number of Restricted Share Units included in the grant before the Merger by 0.792802.
