Viacom Inc.

The retransmission consent will make it possible for Comcast subscribers in CBS owned-and-operated markets to receive CBS's industry leading lineup of high definition television programming, including CBS's broadcast of Super Bowl XXXVIII on February 1, 2004.

Under the terms of the affiliation agreements, Viacom's MTV Networks (including Spike TV, Comedy Central, CMT and the MTVN Digital Suite) and the BET Networks will continue to be available on Comcast systems nationwide.

Additionally, Comcast will augment its digital suite of services by launching Nicktoons and MTV Hits and increasing the distribution of MTV2, Nickelodeon GAS, VH1 Classic and VH1 Country. Mel Karmazin, President and Chief Operating Officer of Viacom, Inc., said, "This company-wide agreement between two industry leaders is unprecedented and is a major extension and enhancement of the long-standing and successful relationship between our two companies. We are very pleased that we can continue to provide Comcast subscribers with Viacom's popular array of high- quality branded entertainment, sports, news and event programming. "Sumner and I want to salute Brian Roberts and the entire Comcast team on their foresight in extending our partnership in a way that will provide substantial value to both companies, and will open up new business opportunities for the future.
