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
