PART 1

GENERAL TERMS AND CONDITIONS

(Continued)

13.6 Shipper shall indemnify Questar and hold it harmless from all

suits, actions, regulatory proceedings, damages, costs, losses and expenses

(including reasonable attorney fees) arising out of the failure of the gas

tendered by shipper to conform to the quality specifications set forth in §§

13.1 through 13.3, including any injury or damage done to Questar's

facilities. Questar may elect to accept any off-specification gas in the

quantities and at the time periods as Questar determines will not adversely

affect or hamper Questar's ability to provide service under this tariff.

13.7 Acceptance of gas that does not conform to these specifications is

at the election of Questar, and acceptance of the gas does not constitute any

waiver of Questar's right to refuse to accept similarly nonconforming gas.

13.8 Questar will not be required to accept gas at any point of receipt

that is of a quality inferior to that required by shipper or a third party at

any point of delivery on Questar's system.
