GENERAL TERMS AND CONDITIONS

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 an interruptible 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 §

15 of these General Terms and Conditions.

12.7 Availability of receipt and delivery point information.

Replacement Shippers may obtain information through Questline or Overthrust's

web site regarding Overthrust's ability to provide transportation service

between the receipt and delivery points desired by the replacement Shipper.
