         and Cogene LP pursuant to certain registration rights assigned to RCMLP
         and Cogene LP is not declared effective by the Securities and Exchange
         Commission or if RCMLP or Cogene LP have not paid the remaining
         $15,200,000 or $3,800,000, respectively, of the purchase price for the
         shares of Common Stock by February 1, 2004, RCMLP and Cogene will

         that RCMLP and Cogene purchased from the Estate and the Foundation in
         the July 10, 2003 transaction, and the Estate and the Foundation will

         and Cogene, respectively, on July 10, 2003 for these shares of Common
         Stock. See Item 5(c) for a further description of the purchase price
         payment obligations of RCMLP and Cogene LP. The stock purchase
