          universities, governmental institutions and similar entities
          various transmission and distribution engineering, procurement
          and construction services, including construction of transmission
          and distribution lines, procurement of materials, construction of

          wholly-owned subsidiary, Cinergy Customer Care, Inc., to market
          utility billing services and/or utility call center services to

          a pilot basis a service contract program (called "Appliance
          Protection Plus") covering parts and labor for mechanical
          breakdowns of existing appliances and HVAC systems.  

     f.   Customer Financing.  In tandem with a bank, Cinergy Solutions
          continued marketing "Quick Credit," a financial services program
          providing residential, commercial, and institutional customers
