(e) Inaccurate Meter


In the event a meter is out of service, or registering inaccurately, the quantity of

natural gas received or delivered shall be determined,


(i) By using the registration of any check meter or meters if installed and

accurately registering, or, in the absence of (i),


(ii) By correcting the error or the percentage of error if ascertainable by

calibration, test, or mathematical calculation, or in the absence of both (i)

and (ii), then


(iii) By estimating the quantity of receipts or deliveries during periods under

similar conditions when the meter was registering accurately.


(f) Verification


The accuracy of Seller's measurement equipment shall be verified by Seller at

reasonable intervals, and, if requested, in the presence of representatives of Buyer,

but Seller shall not be required as a matter of routine to verify the accuracy of such

equipment more frequently than once in any thirty (30) day period.


In the event either party shall notify the other that it desires a special test of any

measuring equipment, including any measuring equipment involving the accurate billing

of the natural gas delivered to the New York Companies, the parties shall cooperate to

secure a prompt verification of the accuracy of such equipment. The expense of such

special tests as may be requested by Buyer shall be borne by Buyer if the measuring

equipment, by such tests, is found to be correct.


(g) Adjustment for Inaccuracy


If, upon test, any measurement equipment is found to be inaccurate, such equipment

shall be adjusted at once to record correctly, and the amount of error shall be

determined by the most accurate method feasible. If, upon test, any measurement

equipment is found to be inaccurate by an amount exceeding two percent (2.0%) in the

measurement of gas quantities since the last preceding test, then the calculated

deliveries of gas shall be adjusted to compensate for such error. Such adjustment

shall be made for such period of inaccuracy which is definitely known. If the period

of inaccuracy is not definitely known or agreed upon, such correction shall be for a

period extending over one-half of the time elapsed since the date of the last test,

not exceeding a correction period of sixteen (16) days.


Measurement data corrections should be processed within six (6) months of the

production month with a three (3) month rebuttal period. This standard shall not

apply in the case of deliberate omission or misrepresentation or mutual mistake of

fact. Parties' other statutory or contractual rights shall not otherwise be

diminished by this standard.


(h) Maintenance of Records


Seller and Buyer shall preserve all original or equivalent electronic test data,

charts, or other similar records for a period required by the applicable rules of

regulatory agencies having jurisdiction.
