EXHIBIT 99.1 SIMON FILES SUIT AND IS NAMED AS A DEFENDANT WAKEFIELD, Mass., Oct. 30 /PRNewswire/ -- Simon Worldwide, Inc. (Nasdaq: SWWI) announced that its subsidiary Simon Marketing, Inc. (SMI) has filed suit against McDonald's Corporation in California Superior Court for the County of Los Angeles. Simon Worldwide also announced that it and SMI were named as defendants, along with Jerome P. Jacobson, a former employee of SMI, and certain other individuals unrelated to Simon Worldwide or SMI, in a complaint filed by McDonald's Corporation in the United States District Court for the Northern District of Illinois. The complaint filed by SMI seeks to recover damages resulting from the termination of SMI's relationship with McDonald's Corporation. The McDonald's Corporation complaint alleges that SMI has engaged in fraud, breach of contract, breach of fiduciary obligations and civil conspiracy and alleges that McDonald's Corporation is entitled to indemnification and damages of an unspecified amount. The McDonald's Corporation lawsuit arises from the allegedly fraudulent actions of Mr. Jacobson and the other named individuals unrelated to SMI in connection with the McDonald's promotional games administered by SMI. Simon intends to vigorously defend itself against the allegations of the complaint but is unable to predict the outcome of the suit, or of its suit against McDonald's Corporation, and the ultimate effect of the suits, if any, on the financial condition of Simon Worldwide or SMI.
