Sonic to Acquire DivX

Combination Creates Digital Video Delivery Powerhouse; Streamlines "Over the Top" Distribution of Hollywood Movies

NOVATO, California and SAN DIEGO, June 2, 2010 - Sonic Solutions(R) (Nasdaq: SNIC) and DivX, Inc. (Nasdaq: DIVX) today
jointly announced that they have signed a definitive merger agreement for
Sonic Solutions to acquire DivX, Inc., a leading digital media company, based
in San Diego, California. Under the terms of the agreement, approved by the
boards of directors of both companies, Sonic would acquire all the
outstanding shares of DivX and merge DivX operations into those of Sonic.
DivX stockholders would receive a combination of cash and stock equal to
US$3.75 in cash and 0.514 shares of Sonic common stock for each share of DivX
they hold. The acquisition, which is expected to close in September 2010, is
subject to approval of the shareholders of both companies as well as
applicable regulatory approvals and customary closing conditions.

For more than 20 years, Sonic has been the leader in developing
technologies for the preparation and delivery of entertainment content in
popular formats - CD, DVD, Blu-ray Disc and most recently Internet delivery
of video. The acquisition of DivX is expected to advance Sonic's mission to
deliver technology that makes it easy and convenient for retailers, online
services, Hollywood studios, and manufacturers of CE and mobile devices to
distribute premium digital video content over the Internet. DivX is expected
to enable Sonic to deepen and broaden the technology it offers for
Internet-based video delivery and expand its relationships with leading
retailers and consumer electronics manufacturers.

DivX is a leading digital media company that enables consumers to enjoy a
high-quality video experience across any kind of device. The DivX brand is
recognized worldwide and supported by a community of millions of consumers.
DivX technology - encoders for formatting video, decoders for playback, and
digital rights management (DRM) for content protection - resides on over 300
million devices shipped into the global market from all major CE
manufacturers including over 8,500 models of digital televisions, DVD and
Blu-ray Disc players, and over 80 different mobile handsets. In addition, the
DivX web properties enjoy more than 12 million unique visits each month.

Sonic believes that the acquisition of DivX will provide a number of key
benefits:

    - The acquisition is expected to be accretive to Sonic's shareholders,
      potentially doubling fiscal year 2012 earnings per share on a non-GAAP
      basis.

    - The DivX technologies are expected to give Sonic a more extensive
      solution for Internet video delivery including the dominant tools for
      content preparation in "the cloud," video playback, and Hollywood-
      approved DRM.

    - DivX is expected to provide leverage to Sonic's strategy of consumer
      electronics deployment - the DivX player and DRM is deployed in
      products from more than 150 different CE manufacturers worldwide on
      millions of devices.

    - The DivX brand is known worldwide as an indicator of compatibility,
      quality, and ease of use.

Overall, the combination of DivX technology, capabilities, and market
position is expected to advance Sonic's mission: to make publishing,
delivery, and enjoyment of movies over the Internet as easy and widespread as
DVD delivery is today.

"Our studio, storefront, and consumer electronics partners agree: they
want a clear and efficient path to deliver premium content to their
customers," said Dave Habiger, president and CEO of Sonic Solutions. "The
combination of Sonic and DivX promises to be the foremost provider of
platforms, tools, and technologies for the efficient delivery of premium
video entertainment to virtually any type of consumer electronics device. We
expect DivX's deep technology and broad deployment in the CE and mobile areas
to give us significant leverage as we expand and enhance our RoxioNow premium
entertainment platform."

"Sonic and DivX are both market leaders in digital media and share
similar visions about a better media future for consumers," stated Kevin
Hell, CEO of DivX. "We also share similar cultures and both recognize the
tremendous market opportunity that lies ahead for Internet video services. By
combining our products, technologies, partnerships, and talented employees,
we immediately create a complete end-to-end delivery platform for digital
media, with expanded reach and capacity, at a perfect time to capitalize on
the market's rapid development. With the acquisition of DivX, Sonic should be
extremely well positioned to serve existing customers, attract new partners,
and increase our market presence and potential."

The current Sonic management team (including Dave Habiger, Clay Leighton,
Paul Norris, Mark Ely, and Matt DiMaria) will lead the combined company,
augmented with key managers and executives from DivX. Kevin Hell, DivX's
chief executive officer, Dan Halvorson, DivX's chief financial officer and
executive vice president, operations, and David Richter, DivX's executive
vice president, business & legal affairs and general counsel, will be
cooperating closely with the Sonic team to close the transaction and
integrate the companies, but will not continue in the combined company in
their current positions. Following completion of the merger, DivX
stockholders will own approximately 35% of the combined company's capital
stock. Sonic expects to add two members of the DivX board of directors, to be
named later, to its board at the closing of the transaction.

Oppenheimer & Co. is acting as DivX's exclusive financial advisor in the
transaction.
