interests of the Company to increase the size of the Company's Board of
Directors to 11 members; and

         WHEREAS, the Amending Purchasers wish to amend the Agreement as herein
provided;

         NOW, THEREFORE, it is agreed:

         Purchasers agree to take any actions necessary so that the Board will
         be comprised of eleven (11) directors. The Company and the Purchasers
         agree to take any actions necessary so that, as of March 23, 2000, the
         Series F Directors shall consist of Adam H. Clammer, James H. Greene,
         Jr., Henry R. Kravis, Alexander Navab, Jr. and George R. Roberts, the

         (such approval not to be unreasonably withheld) is appointed or elected
         to the Board.
