that in lieu of a recording calorimeter, Transporter may determine

the Heat Content on the basis of samples taken at periodic

intervals. If periodic determinations of Heating Value are made,

the initial determination is to be made within sixty (60) Days

after the date of initial deliveries of Natural Gas under an

executed Service Agreement and subsequent determinations shall be

made each three (3) Months thereafter. The recording calorimeter

mentioned herein shall be tested periodically using a reference

sample of Natural Gas of known Heating Value.

delivered under an executed Service Agreement:
