Agreement(s) between the parties hereto:  NONE

8.     OTHER PROVISIONS:

8.1    Subject to the terms of this Agreement as it may be amended from time to
       time, Shipper may deliver or cause to be delivered to Northern, at the
       suction side of Northern's Fort Buford Compressor Station located in
       Section 4, Township 151 North, Range 103 West, McKenzie County, North
       Dakota ("Fort





                                        2
   3
       Buford"), all or a portion of the quantities of gas under this Agreement
       that Shipper desires Northern to compress.  Northern agrees to accept
       and compress, on an interruptible basis, such gas delivered to it by
       Shipper under this Agreement, and to redeliver such gas for the account
       of Shipper to Northern Border Pipeline Company ("NBPL") at the discharge
       side of Northern's Fort Buford Compressor Station for subsequent
       transportation by NBPL.  Shipper agrees to pay the maximum
       transportation rate(s) as set forth in the tariff, which includes the
       charge for compression service at Fort Buford.  Shipper shall not have
       the right to use this agreement solely for compression service at Fort
       Buford.  Shipper shall bear a fuel use charge of 1.25% of gas quantities
       delivered to Northern at the suction side of Fort Buford. Shipper shall
       be required to nominate, in accordance with Section 3, "Nominations" of
       Subpart A, of the General Terms and Conditions of this Tariff, NNG/NBPL
       Fort Buford suction/discharge and those quantities it desires Northern
       to compress at Fort Buford under this Agreement.

8.2    Shipper understands and acknowledges that Shipper is responsible for
       ensuring that the upstream transporting pipeline which delivers gas for
       Shipper to Northern at the Point(s) of Receipt has capacity on its
       system to effectuate deliveries for Shipper's account, and that the
       downstream party which receives gas from Northern at the Point(s) of
       Delivery hereunder for Shipper's account has capacity on its





                                        3
   4
       system to receive such gas.  Accordingly, Shipper shall remain
       responsible under this Agreement for all charges set forth in Section 4,
       "General" of this Agreement, notwithstanding Shipper's inability to
       cause gas to be delivered to Northern at the Point(s) of Receipt and/or
       received by the downstream party at the Point(s) of Delivery hereunder.

9.     ADDITIONAL TERMS AND CONDITIONS:  The additional Terms and Conditions

1.2    Northern agrees to transport overrun volumes and throughput peaking
       volumes as defined in Section 5, "Overrun and Throughput Peaking," of

       conditions of Northern's FERC Gas Tariff and Rate Schedule TI.

SECTION 2.  RECEIPT AND DELIVERY

2.1    Shipper agrees to tender, or cause to be tendered, gas for
       transportation at the Point(s) of Receipt identified in Appendix "A" at

       such pressure may vary from time to time, not to exceed the maximum
       allowable operating pressure.

2.2    Northern agrees to transport and deliver gas to Shipper, or for
       Shipper's account, on an interruptible basis at the Point(s) of Delivery

       of the notice to correct the information to keep the Agreement in
       effect.
