Northwest Pipeline Corporation Declared Entitlement Period

April 3, 2008

Northwest Pipeline Corporation (Northwest) has provided notice of a Stage II Declared Entitlement Period for overruns beginning on the gas day of April 4, 2008 until further notice. A Stage II Overrun Entitlement will subject Paiute to penalties for any gas day during the Declared Entitlement Period on which the total quantity of gas taken by Paiute is at least 8% greater than the confirmed nominations for delivery by Northwest into Paiute’s system. Paiute therefore is issuing an Operational Flow Order for overruns in accordance with Section 5.2(b) of the General Terms and Conditions (GT&C) of Paiute’s tariff.

Accordingly, pursuant to Section 5.2.(b) of the GT&C, Paiute hereby provides notice that each shipper should endeavor to limit its actual takes so as not to exceed its Daily Scheduled Quantity for each day of Northwest’s Declared Entitlement Period. Volumes taken in excess of a shipper’s Daily Scheduled Quantity shall constitute an Unauthorized Daily Overrun and will be subject to the penalties described in Section 5.2.(b)(3) of the GT&C, in the event that Paiute is assessed penalties by Northwest.

The following information is provided in accordance with Section 4.6(f) of the GT&C:
