  RSA Security Inc.(the "Company") has been notified that a shareholder derivative complaint was filed in the United States District Court, District of Delaware, on May 31, 2006 naming the Company as nominal defendant and also naming as defendants current members and one former member of the Company's Board of Directors and current and former employees of the Company (collectively, the "Defendants").  The complaint alleges purported violations of state and federal law in connection with certain stock option grant practices from October 1999 to the present.  The complaint seeks monetary damages in unspecified amounts, equitable and injunctive relief, including disgorgement of profits obtained by certain of the Defendants and the repricing or cancellation of certain stock options held by the Defendants, expenses and costs of the action, and other relief as the Court deems just and proper. The Company and its directors intend to review the allegations and respond appropriately.
