PART 1

GENERAL TERMS AND CONDITIONS

(Continued)

10.3 Adding and deleting points or changing capacity at primary receipt

and delivery points. 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 equivalent capacity at

one or more existing receipt or delivery points or (2) request and pay for

additional primary capacity.

Amendment requests shall be posted no later than 9:00 a.m. the day

nominations are due. Questar will evaluate amendment requests in a timely

manner except as limited by § 5.13.

Approved requests to change primary receipt or delivery points or

shipper's RDC will be posted on Questline by 10:00 a.m. on the third business

day following the amendment request date except for limitations explained in §

5.13 which will be posted the third business day following the bid period.

Questar will not allow amendments to contracts if the result of the

requested amendment impairs Questar's ability to provide firm service. Any

capacity at receipt and delivery points that becomes available through the

expiration of a firm transportation agreement will be sold according to the

bidding procedures outlined in §§ 5 and 7, and shall not be available for

primary receipt or delivery-point changes unless Questar, without undue

discrimination, agrees otherwise.
