Customer notifies the other party that it desires a special test of any measuring

equipment, Pipeline and Customer shall cooperate to secure a prompt verification of the

accuracy of such equipment. In the event that a special test is requested by other

Pipeline or Customer and, after test, the equipment is determined to register no greater

than two percent, either high or low, the requesting party shall pay all costs for said test.

24.3 Correction of Metering Equipment - Any meter found, on test, to register not more

than two percent (2%) high or low shall be deemed to be correct as to past

measurements but shall be corrected to record accurately. In the event any meter, upon

test, proves to be more than two percent (2%) high or low, adjustment shall be made to

fully correct the readings of such meters; provided, however, that if the period in which

the error occurred is not known or cannot be agreed upon, then the period shall be

deemed to be either the last half of the time elapsed since the last test, or the last thirty

(30) Days, whichever is the lesser period. If a meter is out of repair or is being tested or

in the event that Pipeline's meters become inoperative or manifestly in error and

Customer has not installed a check meter or meters as herein provided, or if such check

meters have been installed and fail accurately to register or are manifestly in error, then

the quantity of Gas delivered during the period Pipeline's meter or meters were

inoperative or manifestly in error shall be determined by estimating as nearly as possible

the quantity of Gas delivered hereunder during like periods under similar conditions when

such meter was registering accurately or correctly within the tolerance set forth herein.

24.4 Customer shall be entitled to install and operate at its own expense near the Point(s)

of Delivery such meter or meters of standard type as shall enable Customer to check the

amount of Gas delivered. If Customer shall exercise this right of installing and operating

check meters, then in the event of failure of Pipeline's meters to register accurately at

any time, the registration of Customer's check meters shall be taken as the current

quantity of Gas delivered to Customer by
