This communication includes statements about future economic performance, finances, expectations, plans and prospects of Sonic Solutions (“Sonic”) and DivX, Inc. (“DivX”), both individually and on a consolidated basis, that constitute forward-looking statements for purposes of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from those expressed in or suggested by such statements, including, but not limited to, the following: (1) the parties may not obtain the requisite shareholder or regulatory approvals for the transaction; (2) the anticipated benefits of the transaction may not be realized; (3) the parties may not be able to retain key personnel; (4) the conditions to the closing of the transaction may not be satisfied or waived; (5) the impact of general economic conditions on the businesses and results of operations of the two companies; and (6) other factors set forth in Sonic’s and DivX’s most recent Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q filed subsequent to the Annual Reports and other documents filed by them with the Securities and Exchange Commission (“SEC”) and available on or through their respective corporate websites, www.sonic.com and www.divx.com. In light of the inherent risks and uncertainties in all forward-looking statements, the inclusion of such statements in this communication should not be considered as a representation by Sonic, DivX or any other person that Sonic’s or DivX’s objectives or plans, both individually and on a consolidated basis, will be achieved. These risks, as well as other risks of the consolidated company may be different from what the companies expect and each party’s management may respond differently to any of the aforementioned factors. These risks, as well as other risks associated with the transaction, will be more fully discussed in the joint proxy statement/prospectus that will be included in a Registration Statement on Form S-4 to be filed by Sonic with the SEC. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date on which they are made. For further information regarding cautionary statements and factors affecting future business or financial results of Sonic or DivX, please refer to their most recent Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q filed subsequent to the Annual Reports and other documents filed by them with the SEC and available on or through their respective corporate websites, www.sonic.com and www.divx.com.
