GENERAL TERMS AND CONDITIONS (continued)

other that it desires a special test of any measuring

equipment, the parties shall cooperate to secure a prompt

verification of the accuracy of such equipment. The

expense of any special test, if called for shall be borne

by the requesting Party if the measuring equipment tested

is found to be in error not more than two percent (2%).

If, upon test, any measuring equipment is found to be

in error by not more than two percent (2%), any previous

recording by such equipment shall be considered accurate

in computing deliveries of gas, but such equipment shall be

adjusted at once to record accurately.

If, upon test, any measuring equipment shall be

found to be inaccurate by an amount exceeding two percent

(2%), 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 one-half (1/2) of the time

elapsed since the date of the last test.

4.6 Measurement Closing - The closing of measurement shall be no

later than the fifth (5th) business day after the close of the

production month. Any meter adjustment that occurs after the

closing of measurement shall be treated as a prior period

adjustment. If actual quantities are not available,

quantities will be estimated by the measuring party.

4.7 Correction of metering errors - failure of meters:

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

inaccurately, the volume of gas delivered shall be determined:

(a) by using the registration of any check meter,

telemeter or meters, if installed and accurately

registering; or, in the absence of (a);

(b) by correcting the error if the percentage of error is

ascertainable by calibration, tests or mathematical

calculation; or in the absence of both (a) and (b),

then;

during periods under similar conditions when the

meter was registering accurately.
