                 of Natural Gas and Other Related Hydrocarbon Fluids",
                 as such publication may be revised from time to time
                 (hereinafter referred to as "AGA Report No. 3); or
   
            (2)  A turbine meter, designed, installed, maintained and
                 operated as recommended in the latest issue of American
                 Gas Association Transmission Measurement Committee Report
                 No. 7, entitled "Measurement of Fuel Gas by Turbine
                 Meters", as such publication may be revised from time to
                 time (hereinafter referred to as "AGA Report No. 7"); or
   
            (3)  A positive displacement meter, installed and operated in
                 accordance with generally accepted industry practices.
   
       (b)  Auxiliary measuring equipment shall be installed, maintained
            and operated in accordance with generally accepted industry
            practices.
   
    6.2(a)  The volume of Gas delivered to Seller or redelivered to or
            for the account of Customer shall be calculated by means of
            either an electronic flow computer, or by the processing of
            meter charts, in either case in the following manner:
   
            (1)  When the measuring equipment is an orifice meter, the
                 flow of Gas through the meter shall be computed in the
                 manner recommended in AGA Report No. 3, properly using
                 all factors set forth therein.
   
            (2)  When the measuring equipment is a turbine meter, the volume
                 of Gas delivered through the meter shall be computed in the
                 manner recommended in AGA Report No. 7, properly using all
                 factors set forth therein.
   
            (3)  When the measuring equipment is a positive displacement
                 meter, the volume of Gas delivered through the meter shall
                 be computed by properly applying, to the volume delivered
                 at flowing Gas pressures and temperatures, correction
                 factors for (i) absolute static pressure, (ii) flowing Gas
                 temperature, and (iii) compressibility ratio.
   
       (b)  The volume of Gas injected or withdrawn hereunder shall be
            computed using the standards and factors determined as follows:
