Sonic Solutions Completes Acquisition of InterActual Technologies

Marin County, California (February 19, 2004) — Sonic Solutions (Nasdaq: SNIC), the leader in DVD/CD creation software, today announced that it completed its acquisition of InterActual Technologies on February 13, 2004.

Since the introduction of the DVD-Video format in 1997, InterActual has established the de facto standard for seamlessly connecting Hollywood DVD-Video content with both Web- and high-end ROM-based bonus features. Sonic believes that with the integration of InterActual’s technology, Sonic will be able to offer its professional customers an enhanced DVD product line. The acquisition will increase Sonic’s portfolio of licensable technologies and permit Sonic to add new features to its DVD-related consumer PC applications.

In connection with the recruitment of employees in this acquisition and the recruitment of other employees in the future, Sonic adopted a 2004 Stock Incentive Plan and reserved 2 million shares of common stock solely for the grant of “inducement” stock options and other stock-based awards.

In connection with the InterActual acquisition 22 employees of InterActual Technologies, who became non-executive employees of Sonic following the acquisition, were granted employment inducement stock option grants to purchase a total of 139,500 shares of Sonic common stock. The number of shares involved in these grants amounts to less than 1% of the outstanding common shares of Sonic. All these option grants have an exercise price of $20.38 per share and will vest over a four-year period.
