GENERAL TERMS AND CONDITIONS

(continued)

11.5 Proration of Impaired Deliveries Due to Capacity Shortage on Transporter's System

Interruptible transportation service provided by Transporter shall be (i) interrupted

or curtailed for reasons of force majeure or when necessary in Transporter's sole

opinion and judgment to meet its system operational requirements or its ability to meet

its obligations under its firm transportation agreements, or (ii) interrupted or

curtailed due to any other operational considerations to be determined in the

reasonable discretion of Transporter.

If at any time Transporter does not have sufficient capacity available for reasons of

force majeure or due to any other operational considerations to be reasonably

determined by Transporter, to enable Transporter to deliver to Shippers under all of

Transporter's rate schedules the quantities of gas which Shippers may then require up

to the quantities of gas Transporter has then scheduled to deliver to Shippers, then

deliveries to such Shippers shall be curtailed in accordance with the following

priorities of service:

1) Overrun transportation quantities and interruptible transportation quantities

nominated in excess of contract quantities and scheduled pursuant to Section 22 of

these General Terms and Conditions -- based on lowest price;

2) Firm transportation quantities -- on a pro rata basis, based on scheduled

quantities.

If at any time Transporter does not have sufficient capacity due to an EFBH Shipper's

failure to comply with its minimum flow obligations under Rate Schedule EFBH, then firm

transportation quantities under Rate Schedule FTS-3 shall be curtailed on a pro rata

basis, based on scheduled quantities.
