GENERAL TERMS AND CONDITIONS

(b) Measuring Equipment Out of Repair. If, for any reason, any

measuring equipment is 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 such period shall be estimated by the parties on the basis of

the best data available using the first of the following methods which is

feasible:

(i) By using the registration of any check measuring equipment

installed and accurately registering; or

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

ascertainable by calibration, test or mathematical calculations;

(iii) By estimating the quantity of delivery by deliveries during

a preceding period under similar conditions when the meter was

registering accurately.

inoperative or inaccurate, it shall be adjusted to register correctly. The

amount of error shall be determined by the most accurate method found

feasible, and, if the error shall have resulted in an error of more than two

percent (2%) in the measurement of gas delivered, then the calculated

deliveries of gas through such meter shall be accurately adjusted to

compensate for such error. Such adjustment shall be made for such period of

inaccuracy as may be definitely known, or if not known, then for one-half the

period since the date of the last meter test. Measurement data corrections

must be processed within six (6) months of the production month with a three

(3) month rebuttal period. This time limitation will not apply in the case of

deliberate omission or misrepresentation or mutual mistake of fact. Also, the

parties' 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.
