PART 1

GENERAL TERMS AND CONDITIONS

(Continued)

10.4 Flexible use of alternate receipt and delivery points. A firm T-1

or NNT 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 derogate the rights of the releasing shipper by

adding or deleting primary receipt and delivery points or changing shipper's

RDC at primary receipt and delivery points unless authorized in writing by the

releasing shipper.

10.5 Priority at alternate receipt and delivery points. A shipper's

priority at alternate points shall be determined according to § 9.

10.6 Nominations to and rights of firm and replacement shippers at

alternate points. A firm T-1 or NNT shipper or replacement shipper must

follow Questar's nomination procedures to flex to alternate receipt and

delivery points. A firm or replacement shipper's right to flex to alternate

receipt and delivery points shall be subordinate to the primary rights of

other firm shippers at those points, but as provided by § 9 to this tariff,

will have priority over interruptible transportation and authorized overrun

service.

10.7 Right of shippers to renominate if bumped. If a firm T-1 or NNT

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, Questar 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 §

11 of these General Terms and Conditions.

10.8 Availability of receipt and delivery point information.

Replacement shippers may obtain information through Questline or Questar's

web site regarding Questar's ability to provide transportation service

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