General Terms and Conditions - continued

(2) If, upon any test, any measuring equipment shall be

found to be inaccurate by an amount exceeding two (2)

percent, then any previous readings of such equipment

shall be corrected to zero error for any period which

is known definitely or agreed upon. In case the

period is not known definitely or agreed upon, such

adjustment shall be for a period extending over

one-half of the time elapsed since the date of last

test but not exceeding a correction period of thirty

(30) days.

b. If for any reason Transporter's meters are out of service

or out of repair so that the quantity of gas delivered is

not correctly indicated by the reading thereof, the gas

delivered during the period such meters are out of service

or out of repair shall be estimated and agreed upon on the

basis of the best data available, using the first of the

following methods which shall be feasible:

(1) By using the registration of any check meter or

meters if installed and accurately registering;

(2) By correcting the error if the percentage of error is

ascertainable by calibration, test or mathematical

calculation; or

(3) By estimating the quantity of delivery based on

deliveries during preceding period under similar

conditions when the meter was registering accurately.

c. If Transporter institutes a new method or technique of gas

measurement, such as electronic metering, such new method

or technique may be substituted by Transporter in exercise

of its reasonable judgment. Transporter shall promptly

inform Shipper of any such new technique adopted and the

date of its implementation.
