GENERAL TERMS AND CONDITIONS (continued)
   
          6.5  If a new method or technique is developed
          with respect to Gas measurement or the
          determination of the factors used in such Gas
          measurement, such new method or technique may be
          substituted upon mutual agreement thereto by both
          parties.
   
          6.6  The parties agree to preserve for a period of
          at least three (3) years or such longer period as
          may be required by public authority, all test
          data, charts, if any, and other similar records.
   
          6.7  In accordance with the provisions of Sections
          6.3 and 6.4 of the General Terms and Conditions,
          Seller will use the best information available to
          close its allocation of quantities for a service
          Month.  The cutoff for the closing of measurement
          is five (5) Business Days after the business
          Month.  To the extent that adjustments are made
          after the date of such close such adjustments
          ("Prior Period Adjustments" or "PPA") shall be
          treated under this Section 6.7.  If the PPA are
          due to the correction of measurement data or
          reallocation of volumes, such adjustments should
          be processed within six (6) Months of the
          applicable service Month.  If the affected party
          disputes the as-adjusted quantity it is entitled
          to rebut the basis for the PPA, but only if it
          does so within three (3) Months of the processing
          of the as-adjusted quantity.  Notwithstanding the
          above specified deadlines for processing/rebutting
          PPA, such deadlines shall not apply in the case of 
          deliberate omission or misrepresentation or mutual
          mistake or fact.  Parties other statutory or
          contractual rights shall not be diminished by this
          standard.
   
7.   QUALITY
   
          7.1  Heat Content.  Heat content shall mean the
          gross heating value per cubic foot of Gas received
          or delivered hereunder.  Such Gas shall have a
          heat content not less than 967 Btu per cubic foot
          nor more than 1100 Btu when determined on a dry
          basis.  Seller shall have the right to waive such
          Btu content limits if, in Sellers sole opinion,
          Seller is able to accept Gas with a Btu content
          outside such limits without affecting Sellers
          operations.  The total heating value per cubic
          foot of Gas shall be determined by one of the
          following methods:
   
                    (a)  by means of an instrument of
               standard manufacture installed to measure the
               heating value of the Gas.
   
                    (b)  at intervals of not more than six
               (6) Months by means of an instrument of
               standard manufacture and a sample of Gas from
               the Gas stream.
