5. SCHEDULING AND BALANCING

5.1 Buyer shall nominate service under this Rate Schedule in accordance with the

procedures set forth in Section 28.1 of the General Terms and Conditions subject to

(a) and (b) below. Seller, in its sole judgment, may waive any nomination and ranking

deadlines, on a non-discriminatory basis, if Seller determines that operating

conditions permit. Buyer shall nominate receipt point quantities for delivery to the

nominated points of delivery. Such nominated quantities shall be subject to

confirmation by Seller which shall be based on the best operating information

available to Seller. Such confirmed quantity shall be deemed the scheduled quantity.

Buyer and Seller shall have scheduling personnel available to be contacted 7 days a

week, 24 hours a day, and Buyer shall cause the operators at the point(s) of receipt

and delivery to do the same.

(a) Buyer may request to re-nominate gas supplies from available alternative receipt

point(s) during the day (subject to verification and confirmation by Seller) in

accordance to Section 28.1 of the General Terms and Conditions in order to

mitigate unexpected gas production outages. Seller will use all reasonable

efforts to accommodate such requests, when operating conditions on Seller's

system permit.

(b) Buyer may take daily delivery, at the point(s) of delivery set forth in Buyer's

Service Agreement hereunder, of quantities greater than or less than the

quantities scheduled in advance pursuant to this Section 5.1, pursuant to the

procedures outlined in Section 18.1 of the General Terms and Conditions governing

designation of delivery point "swing" services at non-pipeline interconnects;

provided however in no event shall Buyer take delivery of quantities hereunder

greater than the Scheduled Daily Delivery Quantity, as defined in Section 2(g) of

the General Terms and Conditions on a day when interruptible capacity on Seller's

system is restricted or when service hereunder is limited pursuant to the

provisions of Section 11.3(d) of Seller's General Terms and Conditions.

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 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 dt (whichever is greater) or

cumulative imbalances exceeding 5 percent or 1,000 dt (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.
