NEW YORK and SAN JOSE, Calif. — Aug. 10, 2006 — Viacom, Inc. (NYSE: VIA, VIA.B) and Adobe Systems Incorporated (Nasdaq:ADBE) today announced a strategic alliance to develop and deliver Viacom’s exclusive branded content using the Adobe® Engagement Platform. Through this agreement, Adobe will become Viacom’s preferred technology provider for rich media authoring tools and interactive online video solutions, enabling Viacom to deliver content from its television, motion picture and digital properties to online and mobile audiences in compelling ways. The two companies will also work together in developing new media applications leveraging Viacom’s exclusive content and using Adobe’s next-generation developer tools and ubiquitous cross-platform client software.

The Adobe Engagement Platform is a versatile foundation for capturing and holding audiences’ attention through more active and effective applications and media. Through the combined reach of the Adobe Reader® and Adobe Flash® Player clients, which are installed on more than 600 million connected PCs and devices worldwide, the Adobe Engagement Platform enables businesses to connect with customers, no matter which medium they choose.

“This partnership with Adobe is an important step towards ensuring that our company has the most robust and state of the art online and mobile video applications. We are very excited to be working so closely with Adobe, which is a real innovator with a great track record,” said Tom Freston, president and CEO of Viacom.

Viacom will utilize Flash video as an interactive online video solution and provide Viacom-branded content to mobile phone handsets via FlashCast™ channels. Flash video delivers secure, high-quality seamless video experiences. FlashCast is a flexible client-server solution that effectively delivers rich, intuitive branded experiences on mobile devices. Using Adobe technology, Viacom will also develop entirely new applications leveraging content from Viacom properties including MTV, Comedy Central, Spike TV and Nickelodeon.
