       DAIKIN'S DVD AUTHORING BUSINESS JOINS FORCES WITH SONIC SOLUTIONS

                COMBINATION CREATES PROFESSIONAL DVD POWERHOUSE

Marin County (February 28, 2001) - Sonic Solutions (NASDAQ: SNIC) announced
today that it has reached an agreement with Daikin Industries, Ltd., of Japan
under which Sonic will combine Daikin's DVD authoring business with Sonic's
professional DVD operations. Under the terms of the agreement, Daikin will
maintain an equity interest in Sonic Solutions signifying the strategic
importance of the union. Sonic will acquire the Daikin products, including all
intellectual property rights, and carry on development, marketing and sales
activities on a worldwide basis. Further, Daikin will continue to be the
exclusive distributor and service provider of the Daikin-originated authoring
products in Japan.

"The addition of Daikin's technology will further strengthen our leadership
position," said Bob Doris, President of Sonic Solutions. "Daikin introduced
Scenarist, the first authoring application for professional DVD creation, in
1996 and that system is still a `gold standard' in the industry. Sonic has sold
the largest number of professional DVD production systems of any company in the
world. This deal truly combines the best with the best."

"Sonic has been very successful in providing professional users with DVD
production systems," said Mr. Kiyoshi Nakajima, General Manager of Daikin's
Comtec Computer Division in Tokyo, Japan. "We're delighted to join forces with
Sonic to continue to develop and enhance the strong tradition established by
Scenarist, ReelDVD and other Daikin DVD products."

professional DVD powerhouse," said Leon Silverman, Executive Vice President of
Laser Pacific Media Corporation, a leading digital media laboratory based in
Hollywood. "Our Digital Media Services Group specializes in the most demanding
and creative DVD projects, and we make heavy use of both the Sonic and Daikin
applications to provide the best possible product to our clients. We have had a
longstanding and fruitful relationship with Sonic, and combining these product
lines under one roof assures us of continued success in serving the Hollywood
community."
