GENERAL TERMS AND CONDITIONS

(Continued)

(ii) Questar will not post a Conditioning Reimbursement

Factor for the first period January 1, 2008, through April 30, 2008. Any

difference between the amount in § 16.4(a) and net Clay Basin liquids revenues

for the four months ending April 30, 2008, will be adjusted according to §

16.4(c).

2008, Questar will calculate an ARA for the previous 12 months ending April

30th of each year. The ARA will "true up" the difference between (i) the

amounts stated in § 16.4(a) and (ii) amounts recovered by Questar through the

sale of liquids and Conditioning Reimbursement Quantities reimbursed under §

16.3(a). The ARA will be calculated as follows:

ARA = (ALR + CRV) - AMT]

JQI

Where:

ALR = Actual net Clay Basin liquids revenues for the prior 12 months

ended April 30th.

CRV = Value of the Conditioning Reimbursement Quantities reimbursed by

Clay Basin customers during the prior 12 months ended April 30th

as provided in S 16.4(b). The value is calculated by multiplying

the total Conditioning Reimbursement Quantities received each

month by the First of Month Index posting for Northwest Pipeline,

Wyoming Pool for that month as published in "Inside FERC Gas

Market Report." If "Inside FERC Gas Market Report" ceases

publication or to the extent prices are not reported for

Northwest, Wyoming Pool, Questar will select a similar index or

publication and notify shippers of the selection via Questline.

JQI = First of Month Index posting for Northwest Pipeline, Wyoming

Pool for July of each year as published in "Inside FERC Gas

Market Report". If "Inside FERC Gas Market Report" ceases

Northwest, Wyoming Pool, Questar will select a similar index or

publication and notify shippers of the selection via Questline.

AMT = Amount listed in § 16.4(a) for the prior 12 months ending April

30th.

postings section of its internet web site the prior month's actual Clay Basin
