ICAHN /s/ Gail Golden GAIL GOLDEN [Signature Page of Joint Filing Agreement to Schedule 13D with respect to Mylan] SCHEDULE A On January 5, 2001, Reliance Group Holdings, Inc. ("Reliance") commenced an action in the United States District Court for the Southern District of New York against "Carl C. Icahn, Icahn Associates Corp. and High River Limited Partnership" alleging that High River's tender offer for Reliance 9% senior notes violated Section 14(e) of the Exchange Act. Reliance sought a temporary restraining order and preliminary and permanent injunctive relief to prevent defendants from purchasing the notes. The Court initially imposed a temporary restraining order. Defendants then supplemented the tender offer disclosures. The Court conducted a hearing on the disclosures and other matters raised by Reliance. It then denied plaintiffs' motion for a preliminary injunction and ordered dissolution of its temporary restraining order following dissemination of the supplement. Reliance took an immediate appeal to the United States Court of Appeals for the Second Circuit and sought a stay to restrain defendants from purchasing notes during the pendency of the appeal. On January 30, 2001, the Court of Appeals denied plaintiff's stay application. On January 30, Reliance also sought a further temporary restraining order from the District Court. The Court considered the matter and reimposed its original restraint until noon the next day, at which time the restraint was dissolved. The appeal was argued on March 9 and denied on March 22, 2001.
