VIACOM ANNOUNCES $3 BILLION STOCK PURCHASE PROGRAM FOR
POST-SEPARATION “NEW” VIACOM

NEW YORK, December 12, 2005 –Viacom Inc. (NYSE: VIA and VIA.B) today announced that its Board of Directors has approved a stock purchase program under which the new post-separation Viacom Inc. is authorized to acquire from time to time up to $3 billion of its class A and class B common stock. The program will commence following the separation of Viacom into two publicly traded companies, which is expected to be completed December 31, 2005.

New Viacom, which will own MTV Networks, BET, Paramount Pictures, Paramount Home Entertainment and Famous Music, will finance the purchase program using working capital, future cash flows and committed borrowing capacity consistent with new Viacom's credit ratings after the separtion. NAIRI, Inc., a closely held corporation controlled by Sumner Redstone, is expected to enter into an agreement with new Viacom to participate in the program on a pro-rata basis on substantially the same terms on which it currently participates in Viacom’s stock purchase program. The agreement, which has been approved by the disinterested members of Viacom’s Board, is designed to prevent the buyback from increasing NAIRI’s economic interest in new Viacom.
