GENERAL TERMS AND CONDITIONS

(continued)

If either party at any time observes a variation between the designated

meter and the check meter, it will promptly notify the other party

thereof and both parties will then cooperate to secure an immediate

verification of the accuracy of such equipment. Each party shall give

to the other notice of the time of all tests of meters reasonably in

advance of the holding of such tests in order that the other party may

conveniently have its representative present.

5.7 Correction for Errors of Meters

If, upon test, the total measurement error at a meter is found to be in

error not more than 1%, previous recordings of such equipment shall be

considered accurate in computing receipts or deliveries hereunder; but

such equipment shall be adjusted at once to record correctly. If, upon

test, the total measurement error at a meter is found to be inaccurate

by an amount exceeding 1%, at a recording corresponding to the average

hourly rate of flow for the period since the last preceding test , then

any previous recordings of such equipment shall be corrected to zero

error for any period which is known definitely or agreed upon, but in

case the period is not known definitely or agreed upon, such correction

shall be for a period extending one half of the time elapsed since the

date of last test to the nearest day, not exceeding a correction period

of 15 days, unless otherwise agreed to by the parties. Measurement data

corrections shall be processed within six months from the date of

production with a three month rebuttal period. This time limitation will

not apply in cases of deliberate omission or misrepresentation or mutual

mistake of fact. Transporter and Operator's other statutory or

contractual rights shall not otherwise be diminished by this provision.

A meter adjustment or correction becomes a prior period adjustment after

the fifth business day following the production month. Any measurement

prior period adjustments are taken back to the production month.

Refer to Section 5.5 hereof to determine the methods for correction of

deliveries during periods of inaccurate measurement exceeding one

percent (1%).
