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.

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

(or allocate "swing" quantities to service under this Rate Schedule) 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.
