GENERAL TERMS AND CONDITIONS

curtailed pro rata regardless of whether those Shippers are using primary or

alternate receipt and delivery points.

11.3 Overthrust shall provide Shipper as much advance notice of

interruption as is possible under the circumstances in order to permit

Shipper to make the election available under § 11.2(b). Overthrust will

support notification, to be designated by Shipper, through the following

channels: (1) available on Questline's shipper web reports and/or (2) up to

two internet e-mail addresses provided by shipper or (3) additional

electronic notification specified by shipper. Such notice shall state the

discounted rates being paid by other Shippers, the quantities being

transported at such rates and the estimated reduced quantities of gas that

can be transported.

11.4 Overthrust shall have the right, without liability to Shipper, to

interrupt or curtail the transportation of gas for Shipper for reasons of

force majeure; or when necessary, to test, alter, modify, enlarge or repair

any facility or property comprising a part of, or appurtenant to,

Overthrust's pipeline system, or otherwise related to the operation thereof.

Overthrust shall endeavor to cause a minimum of inconvenience to Shipper

because of such interruptions.

12. USE OF RECEIPT AND DELIVERY POINTS

12.1 Designation of primary receipt and delivery points. Shipper's

primary receipt points must be assigned by the Shipper to corresponding

delivery points, subject to available capacity. The total RDC assigned to

Shipper's receipt points must equal the RDC assigned to the corresponding

delivery point. The sum of the receipt point RDC and delivery point RDC must

equal the RDC shown in Shipper's Rate Schedule FT service agreements. The

sum of the firm Shipper's primary receipt and delivery point capacities may

not exceed the Shipper's total RDC.

12.2 Adding and deleting points or changing capacity at primary

receipt and delivery points.

(a) A firm Shipper may add and delete primary receipt and

delivery points and increase or decrease its RDC at primary receipt and

delivery points, subject to available capacity, by amending its

transportation service agreement. A firm Shipper that requests primary firm

capacity at a new receipt or delivery point must either (1) release an

equivalent capacity at one or more existing receipt or delivery points or (2)

request and pay for additional primary capacity.
