CyberSource believes that the class action lawsuit is without merit. Nevertheless, in an effort to minimize the further cost, expense, burden and distraction of litigating the class action lawsuit, on July 13, 2010, the parties filed with the Court a Notice of Settlement and attached Memorandum of Understanding agreeing in principle to the settlement of the lawsuit based upon, among other things, certain additional disclosures requested by the plaintiffs and included by CyberSource in its definitive proxy statement filed with the Securities and Exchange Commission on June 11, 2010. The agreed-upon settlement is subject to the execution of definitive documentation, confirmatory discovery, notice to the shareholder class and final approval by the Superior Court. Upon final approval, the class action lawsuit will be dismissed with prejudice and all claims of the plaintiffs will be released.

The special meeting at which CyberSource shareholders will consider and vote on a proposal to adopt the Agreement and Plan of Merger by and among Visa Inc., Market St. Corp. and CyberSource Corporation is scheduled to take place on July 20, 2010 at 10:00 a.m., local time.
