   Sonic Solutions Receives Notice from Nasdaq Due to Inability to
                        Timely File Form 10-Q

    NOVATO, Calif.--(BUSINESS WIRE)--Feb. 16, 2007--Sonic Solutions(R)
(NASDAQ:SNIC) today announced that it will appeal and request a
hearing before a Nasdaq Listing Qualifications Panel (Panel) in
response to its receipt on February 13, 2007 of a Nasdaq Staff
Determination from The Nasdaq Stock Market stating that Sonic's common
stock is subject to delisting from The Nasdaq Global Select Market.
The notice, which Sonic expected, was issued as a result of Sonic's
inability to timely file its Quarterly Report on Form 10-Q for the
quarter ended December 31, 2006. Timely filing of periodic reports
with the Securities and Exchange Commission is a requirement for
continued listing under Nasdaq Marketplace Rule 4310(c)(14). There can
be no assurance that the Panel will grant Sonic's request for
continued listing.

    As previously announced on February 1, 2007, Sonic has commenced a
voluntary review of its historical and current stock option grant
practices and related accounting. Based on the review, the audit
committee and Sonic management have preliminarily concluded that,
under applicable accounting guidance, Sonic lacks sufficient
documentation for certain historical option grants and that the
measurement dates associated with these option grants will need to be
adjusted. Further, as previously announced, the audit committee, after
consultation with management and the Company's board of directors, has
determined that the Company's annual and interim financial statements
may no longer be relied upon.

    Sonic believes it will have to record additional non-cash charges
for stock-based compensation expense and restate previous financial
statements, and that such charges will be material. Sonic is not yet
able to determine the amount of such charges or the resulting tax and
accounting impact of these actions. Sonic intends to file its restated
financial results and related periodic reports as quickly as possible.

    These risks and uncertainties include, but are not limited to, our
