GENERAL TERMS AND CONDITIONS

(Continued)

10.7 Limitation on Obligation.

Irrespective of the Dth value for annual working gas specified in

shipper's storage service agreement, Questar shall not be obligated to inject

an amount of working gas for shipper that would cause the volume of shipper's

working gas in storage to exceed the annual working gas volume, expressed in

Mcf, specified in shipper's storage service agreement.

10.8 Operational Flow Orders. Questar may issue operational flow

orders (OFO) prohibiting or requiring withdrawal and injection of gas, if

necessary, to protect the integrity of the reservoirs, to test the

facilities, to ensure needed deliverability, to cure storage account balances

or to deal with any operational difficulties resulting from out-of-period

injections and withdrawals. Operational difficulties include, for example,

well freeze-up, malfunction of a compressor, loss of pressure, dehydration

failure at the storage facility or injection or withdrawal of gas by shipper

in excess of scheduled nomination, etc. A shipper shall be afforded

reasonable opportunity consistent with existing operational conditions to

respond to Questar's OFO.
