Amendment I
                                          
                    Amendment to FST Service Agreement #N01719
                                      between
             National Fuel Gas Supply Corporation ( Transporter ) and
                  Connecticut Natural Gas Corporation ( Shipper )
    
                    Effective:  April 1, 1996 to March 31, 1999
    
    
    
   1.    Subject to Section 3 of this Amendment, the following rates will be
   applied to all Transportation Service provided within the Quantity Limits
   set forth in Article I of this Service Agreement:
    
         Reservation                                           (*)
         Gathering amortization surcharge - reservation        $0.1579  
         Commodity                                             $0.0064  
    
   (*)     The sum of monthly charges for Reservation and Gathering Amortization
   Surcharge Reservation will be $0.1579.  The monthly Reservation charge will
   be the result obtained by subtracting the effective Gathering Amortization
   Surcharge from $0.1579. 
    
         Applicable surcharges will be added to the rates shown above, except
   that Transporter shall discount the GRI surcharge to the extent that it can
   do so without decreasing its retained revenues.  
    
    
   2.    Transporter shall apply maximum fuel and loss retention, except that
   no fuel and loss retention shall be applied to transportation from the
   primary withdrawal receipt point.  
    
    
   3.    The rates set forth in Section 1 of this Amendment shall be adjusted
   for any month during which the service provided pursuant to this FST
   Service Agreement (or when capacity under this FST Service Agreement has
   been released by Shipper, service agreements with replacement shippers) is
   used for purposes other than the injection of gas into or the withdrawal of
   gas from Transporter s storage facilities pursuant to the FSS Service
   Agreement between Transporter and Shipper ( Other Purposes ).  In such
   case, the rates to be applied during such month shall be the weighted
   average between the rates set forth in Section 1 of this Amendment and the
   maximum rates provided under Rate Schedule FST set forth in Transporter s
   effective FERC Gas Tariff.  The maximum rates shall be weighted by a
   percentage obtained by dividing the quantity received for transportation
   for Other Purposes by the total quantity received for transportation during
   such month.  The rates set forth in Section 1 shall be weighted by a
   percentage equal to (i) 100% less (ii) the weighting factor applicable to
   the maximum rates.  
    
    


   4.    The parties shall keep the terms of this rate amendment confidential
   and shall not disclose such terms to any other party, except as required by
   applicable law, regulation or legal process. 
    
   5.    The rates set forth in this amendment shall only apply during the
   period commencing April 1, 1996, and ending March 31, 1999.  If this
   service Agreement continues in effect beyond March 31, 1999, the maximum
   rates provided under Rate Schedule FST shall apply, absent a further
   agreement between the parties.  Upon the request of either party, made no
   later than March 1, 1998, the parties shall engage in discussions
   concerning the possibility of a further agreement concerning the rates to
   be in effect following March 31, 1999.
