GENERAL TERMS AND CONDITIONS
                                  (Continued)
   
            (6)  The compressibility ratio factor "s" used in computing
                 the volume of Gas delivered through a turbine meter or a
                 positive displacement meter shall be determined by the
                 equation s = (Fpv)2, in which "Fpv" is the
                 supercompressibility factor determined as described in
                 subparagraph (4) of this subsection (b), above.
   
            (7)  In determining the flowing temperature factor,
                 supercompressibility factor, and compressibility ratio
                 factor "s" for use in computing the volume of Gas
                 delivered through a meter, the flowing Gas temperature for
                 only the period(s) of time that Gas was flowing through
                 the meter shall be used.
   
      6.3   All flow, measuring, testing and related equipment shall be of
            standard manufacture and type approved by Seller.  If
            applicable, Seller or Customer may install check measuring
            equipment, provided that such equipment shall be so installed as
            not to interfere with the operations of the Operator.  Seller,
            or Customer, in the presence of the other party, shall have
            access to measuring equipment at all reasonable times, but the
            reading, calibrating, and adjusting thereof and the changing of
            charts, if any, shall be done by the Operator.  Seller or
            Customer shall have the right to be present at the time of the
            installing, reading, cleaning, changing, repairing, inspecting,
            testing, calibrating or adjusting done by the Operator of the
            measuring equipment.  The records from such measuring equipment
            shall remain the property of the Operator, but upon request, the
            other party may request records, including charts, if any,
            together with calculations therefrom for inspection, subject to
            return within thirty (30) Days after receipt thereof.
            Reasonable care shall be exercised in the installation,
            maintenance and operation of the measuring equipment so as to
            avoid any inaccuracy in the determination of the volume of Gas
            injected and withdrawn.  The accuracy of all measuring equipment
            shall be verified by Operator at reasonable intervals, and if
            requested, in the presence of representatives of the other
            party, but neither Seller nor Customer shall be required to
            verify the accuracy of such equipment more frequently than once
            in any thirty (30) Day period.
   
            If either party at any time desires a special test of any
            measuring equipment, it will promptly notify the other party
            and the parties shall then cooperate to secure a prompt
