          percent of the output of a generating unit capable of generating up to 470 megawatts. The Company is
          obligated to pay Square Butte all of Square Butte's leasing and operating and debt service costs, less any amount 
          collected from the sale of power or energy to others, which shall not have been paid by Square Butte when due. See
