GENERAL TERMS AND CONDITIONS

(c) Determination of cash-out price. The cash-out price or

index shall be adjusted subject to a premium of $1.00/Dth for volumes owed to

Overthrust and subject to a discount of $1.00/Dth for volumes owed to

Shipper. Overthrust will use the "Inside FERC Gas Market Report" first-of-

the-month posting for Questar Pipeline published for the first of the month

following final determination of the cash-out volume. If "Inside FERC Gas

Market Report" ceases publication or to the extent prices are not reported

for Questar Pipeline, Overthrust will select a similar index or publication

and notify Shippers of the selection via Questline.

(d) Overthrust shall credit the account of Shipper for any cash-

out amounts due Shipper.

(e) Shipper shall pay Overthrust for any cash-out amounts due

Overthrust.

(f) Upon payment or crediting of the appropriate cash-out

amounts, Shipper's imbalance will be reduced to zero.

16.6 Credit of Penalty and Cash-Out Revenues. Any penalty or cash-out

revenues that exceed gas purchase and incremental administrative costs will

be credited to all non-offending Shippers in proportion to the revenue

contribution from each non-offending shipper for the month in which the

imbalance occurred, using the following process:

(a) Excess amounts collected during the period January through

June will be credited in March of the following year.

(b) Excess amounts collected during the period July through

December will be credited in September of the following year.

16.7 Imbalances on Inactive Contracts. If Shipper fails for a period

of 60 days to make a nomination on an existing service agreement with an

outstanding imbalance, Overthrust shall, after notification to Shipper,

either purchase or sell Shipper's imbalance inclusive of the ±10% imbalance

tolerance and cashed out pursuant to § 16.5 above. Excess revenues will be

credited according to § 16.6 above.
