INTERRUPTIBLE TRANSPORTATION SERVICE - POOLE ROAD INTERCONNECT

5. RECEIPTS AND DELIVERIES (Cont.)

5.3 Hourly Flow Rate (cont.)

B. Notwithstanding the foregoing limitation, on any Gas Day that Pipeline has

operational capability, Pipeline may grant Customer the flexibility, for that Gas

Day, to vary its hourly Tenders and/or Takes. To request such hourly flexibility,

Customer shall submit a request to Pipeline's Transportation Services Department on

the form provided on the Website, no more than 48 hours and no less than four hours

in advance of flow. Such request shall include Customer's anticipated hourly flow

variations, by hour, for the time period requested. Within two hours of the

receipt of a request, Pipeline shall respond and inform Customer whether the

requested flexibility will be granted; provided, however, that Pipeline shall

respond to requests received after 4:00 p.m. CCT by no later than 9:00 a.m. CCT the

following morning. In evaluating Customer's request for hourly variations,

Pipeline may consider any relevant factors, including but not limited to Pipeline's

current operating conditions, the level of variation requested by all customers,

the level of other scheduled services, and Customer's demonstrated ability to

Tender and/or Take Gas in a timely fashion.

C. Pipeline shall retain the right to rescind flexibility granted under this Section

5.3 at any time and enforce the hourly limitation described in this Section 5.3.

If such flexibility is rescinded, Pipeline shall give Customer as much notice as is

reasonable under the circumstances.

6. EQUALIZATION OF RECEIPTS AND DELIVERIES

Deliveries by Pipeline to Customer, hereunder, shall be approximately equal to Tenders to

Pipeline from Customer for transportation hereunder, less any Gas retained by Pipeline in

providing such transportation service. Pipeline shall have no obligation to Receive Gas if

Customer fails to Take equivalent quantities of Gas Tendered by Customer, and Pipeline shall

have no obligation to Deliver Gas to Customer on any Gas Day that Customer fails to Tender

equivalent quantities to Pipeline; provided, however, that this Section 6 shall authorize

Pipeline to suspend service only to the extent that Customer's Tenders and Takes are not

equivalent.

7. GENERAL TERMS AND CONDITIONS

The General Terms and Conditions of Pipeline's effective FERC Gas Tariff, and any revisions

thereof that may be proposed and made effective from time to time hereafter, to the extent

not inconsistent with the provisions of this Rate Schedule, shall apply to and are made a

part of this Rate Schedule, provided, however, (i) if the GT&C are inconsistent with this

Rate Schedule, the terms of this Rate Schedule shall apply.
