The information in this Item 2.02 of Form 8-K and Exhibits 99.1 and 99.2 attached hereto is being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that Section.

ADDITIONAL INFORMATION

In connection with the proposed merger of DivX, Inc. (“DivX”) into a wholly owned subsidiary of Sonic, Sonic intends to file a proxy statement and other relevant materials with the Securities and Exchange Commission (“SEC”). This press release is not a solicitation of a proxy, an offer to purchase nor a solicitation of an offer to sell shares of Sonic, and it is not a substitute for any proxy statement or other filings that may be made with the SEC with respect to the transaction. When such documents are filed with the SEC, investors will be urged to thoroughly review and consider them because they will contain important information. Any such documents, once filed, will be available free of charge at the SEC's website (www.sec.gov).

Sonic and its directors, executive officers and other members of management may be deemed to be soliciting proxies from shareholders in favor of the DivX transaction. Investors and shareholders may obtain more detailed information regarding the direct and indirect interests in the transaction of persons who may, under the rules of the SEC, be considered participants in the solicitation of these shareholders in connection with the transaction by reading the preliminary and definitive proxy statements regarding the merger, which will be filed with the SEC. Information about the directors and executive officers of Sonic may be found in its definitive proxy statement filed with the SEC on October 1, 2009 and in its Annual Report on Form 10-K for the year ended March 31, 2010 filed with the SEC on June 7, 2010. These documents will be available free of charge once available at the SEC's web site at www.sec.gov or by directing a request to Sonic.
