RATE SCHEDULE ITS-1

Interruptible Transportation Service

1. AVAILABILITY

This Rate Schedule is available for transportation service by Transwestern Pipeline Company, LLC,

(Transporter) for any Shipper, where Shipper has entered into an ITS-1 Service Agreement of the

form contained in Transporter's FERC Gas Tariff.

2. APPLICABILITY AND CHARACTER OF SERVICE

Gas transported by Transporter for Shipper under this Rate Schedule shall be on an interruptible

basis. When capacity is available on Transporter's system, Transporter shall receive for

transportation hereunder the quantity of gas made available by Shipper or for the account of

Shipper for transportation, provided, however, that such quantity shall not exceed the lesser of

(1) the Maximum Daily Transportation Quantity (MAXDTQ) specified in the Service Agreement,

exclusive of Transport Fuel, or (2) the system capacity quantity available to Shipper as provided

in Section 2.3 of this ITS-1 Rate Schedule. Transporter shall make available for delivery to

Shipper at the delivery points as specified in the Service Agreement, subject to available

capacity, the same quantities received as measured, less Transport Fuel, in accordance with

Sections 4 and 22 of the General Terms and Conditions of this Tariff.

2.1 Term

The period of time to be covered by the Service Agreement shall be determined by agreement between

the parties.

2.2 Authorized Overrun Gas

Transporter may, upon request of Shipper, receive, transport and deliver on any day quantities of

natural gas in excess of the MAXDTQ when, in Transporter's sole judgement, the delivery capacity of

its system will permit such receipt, transportation, and delivery without impairing the ability of

Transporter to meet its other delivery obligations.

2.3 Impairment of Delivery

If, on any day, Transporter is unable to receive for transportation the total quantity scheduled

for any Shipper served under this Rate Schedule, due to the lack of system capacity or any other

operational considerations to be reasonably determined by Transporter, then the system capacity

which is available for interruptible transportation service hereunder shall be curtailed in

accordance with Section 11.5 of the General Terms and Conditions of this Tariff.

2.4 Interruptible Service

Transporter's transportation services under this ITS-1 Rate Schedule are to be performed on an

interruptible basis and such services may be interrupted in accordance with the provisions of this

Rate Schedule in whole or in part by Transporter, without notice to Shipper, at any time. Shipper

will protect, defend and indemnify Transporter from and against any and all losses, damages, or

expenses of every kind and character that Shipper or Transporter may suffer, sustain, or be liable

for as a result of any interruption of a service or services commenced in accordance with this

Rate Schedule where such interruption was not caused by Transporter's own wrongful conduct.
