GENERAL TERMS AND CONDITIONS

or more existing receipt or delivery points or (2) request

and pay for additional primary capacity.

12.3 Flexible use of alternate receipt and delivery

points. A firm Shipper, or any replacement Shipper, may

flex to or use any receipt or delivery point on an alternate

basis at which capacity is available. However, a replacement

Shipper may not add or delete primary receipt and delivery

points or change Shipper's RDC at primary receipt and

delivery points unless the terms of Shipper's release allow

for such.

12.4 Priority at alternate receipt and delivery points.

A Shipper's priority at alternate points shall be determined

according to 11.

12.5 Nominations to and rights of firm and replacement

Shippers at alternate points. A firm or replacement Shipper

must follow Overthrust's nomination procedures to flex to

alternate receipt and delivery points. A firm or

replacement Shipper's right to service at alternate receipt

and delivery points shall be subordinate to the primary

rights of other firm Shippers at those points, but as

provided by 11 to this tariff, will have priority over

interruptible transportation and authorized overrun service.

12.6 Right of Shippers to renominate if bumped. If a

firm Shipper or replacement Shipper's nomination at a

receipt or delivery point requires bumping of a Shipper

currently using that receipt or delivery point, Overthrust

will notify the interrupted Shipper and allow that shipper

to nominate the requested transportation volumes at another

receipt or delivery point subject to the intra-day

nomination procedures set forth in Section 15.2 of these

General Terms and Conditions.

12.7 Availability of receipt and delivery point

information. Replacement Shippers may obtain information

through Questline regarding Overthrust's ability to provide

transportation service between the receipt and delivery

points desired by the replacement Shipper.
