Sonic^™ to Acquire InterActual^® Technologies

Combined Company Offers End-to-End Solutions for

Web-Connected DVD Creation and Playback

Marin County, California (February 2, 2004) – Sonic Solutions (NASDAQ: SNIC) today announced that it has entered into a definitive agreement to acquire InterActual Technologies, the leading provider of solutions for integrating DVD content with the Internet and additional on-disc bonus features for $8.8 million in cash. With the acquisition of InterActual, Sonic will further strengthen its leadership position with the Hollywood-based DVD production community and broaden its professional DVD authoring product line with advanced web-linking technologies. In addition, InterActual’s web-enabled DVD playback capabilities will be integrated into Sonic’s consumer DVD software applications as well as its AuthorScript^™ DVD creation engine, enabling Sonic’s bundle OEMs and technology licensing partners to deliver the best possible connected-DVD experience to their customers.

As a result of the acquisition, Sonic will acquire InterActual’s web-enabling technologies including its portfolio of 17 patents and patent applications, the InterActual Player, and all engineering and service operations. Key InterActual executives, including Todd Collart, InterActual’s president, and almost all members of staff will join Sonic’s Professional Products or Advanced Technologies business units. Sonic plans to continue to market the InterActual brand and spotlight logo as part of the Sonic product family. Sonic also plans to continue InterActual’s cross-platform licensing strategy to enable third-party DVD players and authoring solutions to play and access InterActual bonus content.

InterActual is recognized by Hollywood’s top movie studios as the de facto standard for seamlessly connecting DVD-Video content with both web- and high-end ROM-based bonus features such as downloadable commentaries, scene medleys, and image galleries accessible with a DVD-enabled PC. The InterActual Player can be found on hundreds of millions of DVDs, including such blockbuster titles as New Line Cinema’s “Lord of the Rings – The Two Towers,” Disney’s “Pirates of the Caribbean,” Warner Bros.’ “The Matrix Reloaded” and “Harry Potter and The Chamber of Secrets,” Universal’s “Seabiscuit,” and Columbia TriStar’s “Spider-Man.” In 2003 over 70% of the top 25 selling DVDs were InterActual-enabled.

“As the leading provider of DVD creation solutions to Hollywood as well as the leading supplier of DVD and CD creation software on the PC, Sonic is the perfect partner with whom to expand

InterActual’s technology and enhance our service offerings to the content community,” said Todd Collart, president of InterActual Technologies. “Joining forces with Sonic greatly strengthens our ability to deliver cutting-edge Internet-connected technology across a broad-range of platforms, especially for our studio partners.”

“The PC DVD-ROM market segment represents over 44% of U.S.-based DVD viewing households, and this segment is growing dramatically,” said Bob Doris, president and CEO of Sonic Solutions. “InterActual’s industry-leading technology and service operations targeted at highly connected consumers allow us to enhance the world’s best DVD creation technology to our professional authoring customers while enabling our PC and license partners to offer internet-connected DVD playback solutions that deliver a deeply enriched DVD experience for their customers.”

The acquisition is subject to customary closing conditions, including approval by InterActual shareholders. Sonic currently expects to close the acquisition in mid- to late February 2004. Sonic management plans to provide more information regarding the financial and operational impact of the acquisition during the Company’s 3rd Quarter Fiscal 2004 Financial Results Conference call scheduled for 1:30 PM PST (4:30 PM EST) on Tuesday, February 3, 2004.
