               The PBU partners originally believed that they might be able           
          to recover and to market natural gas reserves located in the                
          Prudhoe Bay field.  To date, however, studies conducted by the              
          PBU partners and by State and Federal agencies indicate that                
          natural gas recovery from Prudhoe Bay will not be economically              
          viable given the projected low price of natural gas relative to             
          the high cost of recovering, producing, and transporting natural            
          gas from the Prudhoe Bay field to world markets.  In 1987, Exxon            
          “debooked” (removed from “proved undeveloped” to “uneconomic”)              
          the natural gas reserves in the Prudhoe Bay field.  In 1988, the            
          U.S. Department of Energy (DOE) agreed with that decision and               
          reduced its estimate of North Slope natural gas reserves by 24.6            
          trillion cubic feet.                                                        
               The extensive Prudhoe Bay oil field production facilities              
          and the TAPS pipeline from Prudhoe Bay to Valdez, Alaska, were              
          designed for the recovery, processing, and transportation of                
          crude oil, not natural gas, and it is not anticipated that any              
          significant portion of the Prudhoe Bay oil field production                 
          facilities and the TAPS pipeline would be usable or modifiable              
          for the eventual recovery and transportation of natural gas from            
          the Prudhoe Bay field should recovery of the Prudhoe Bay natural            
          gas someday become economically viable.  That is, it is                     
          anticipated that separate, new wells, processing, and                       
          transportation facilities would have to be constructed for the
