2 Item 1. DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED. AGCO Corporation, a Delaware corporation (the "Company"), previously registered Preferred Share Purchase Rights issued pursuant to a Rights Agreement in 1994. The Rights Agreement contained provisions frequently referred to as "dead hand provisions" pursuant to which certain decisions regarding the Rights were reserved to "Continuing Directors." Recent litigation in Delaware has held that under similar rights agreements these decisions could not be reserved to Continuing Directors. As a result, the Company has amended its Rights Agreement to eliminate the role of Continuing Directors and to instead reserve those rights to the "Independent Directors." A copy of that amendment is attached as an exhibit to this filing. Item 2. EXHIBITS 4.1 Amendment dated as of March 1, 1999, to the Rights Agreement dated as of April 27, 1994, between the Company and SunTrust Bank, Atlanta, a Georgia banking corporation, as successor to Trust Company Bank, a Georgia banking corporation, and Chemical Bank, a New York banking corporation.
