5. SCHEDULING AND BALANCING (Continued)

5.2 Buyer shall have the responsibility to adjust and maintain a concurrent balance

between receipts and deliveries based on the best information available to Buyer.

Seller shall have the responsibility to monitor daily receipts and daily deliveries

during the month based on the best operating information available to Seller

(including electronic gas measurement - estimates or actuals) and shall make such

information available in accordance with Section 29 of the General Terms and

Conditions. Seller shall install the appropriate equipment and facilities on its

pipeline system as determined by Seller to accurately measure gas receipts and

deliveries. Any imbalances between Buyer's deliveries of gas for transportation and

Seller's redeliveries shall be kept to a minimum. For daily imbalances between

receipts and deliveries exceeding 10 percent or 1,000 dth (whichever is greater) or

cumulative imbalances exceeding 5 percent or 1,000 dth (whichever is greater) Seller,

upon notice to Buyer, which notice shall be given at least 24 hours in advance, unless

exigent circumstances dictate otherwise, may issue Operational Controls or Operational

Flow Orders pursuant to Sections 51 and 52 of the General Terms and Conditions to

require adjustments to Buyer's daily scheduling of receipts or deliveries over a

reasonable period of time to maintain a concurrent balance when the operational

integrity of Seller's pipeline system would otherwise be threatened.

5.3 Each month imbalances shall be resolved in accordance with Sections 25 and 37 of the

General Terms and Conditions of Seller's Volume No. 1 Tariff.
