                 of 10/30/97 and filed with FERC on 1/16/98].
            (c)  Charges for Energy and Capacity.  Charges for the sale of
                 energy and capacity shall equal total charges set forth in

foregoing, flood, earthquake, fire, explosion, epidemic, war, riot, civil
disturbance, labor trouble, strike, sabotage, and restraints by court or
public authority which by exercise of due diligence and foresight a Party

            in dollars per kilowatt hour ($/KWH), plus the Actual Curtailed
            Energy Rate, stated in dollars per kilowatt hour ($/KWH), minus
            the Component B Rate ($/KWH) where the Component A Rate and the
            Component B Rate have the following values in the indicated
            months:
