          SYSTEMS (Schedule 1) by a standard service fee, or as otherwise
          agreed in writing between DEI and RSI. This standard service
          fee shall be subject to RSI's reasonable annual adjustment to
          spread RSI's annual related support costs on a pro rata basis
          on written notice.

      11.  This First Amendment shall be binding upon and inure to the
