8.	FURTHER AGREEMENT:

A.	For the period April 1, 2000 through March 31, 2003, the rates for transportation under this Agreement will be a reservation rate of $1.4452 per dth per month. These rates include Volumetric Buyout/Buydown, Dakota and
Transition Cost Surcharges. In addition to the rates stated above, Shipper shall be charged the Minimum Commodity Rate, ACA and Transporter's Use ("Fuel") in accordance with Transporter's FERC Gas Tariff, which is subject to change from time to time.
Shipper shall not be responsible for GRI surcharges unless and to the extent that Transporter is required by the FERC to collect such charges from all similarly situated Shippers and remit such charges to GRI.

B.	If, for any reason, Transporter is prohibited from charging and/or collecting the revenues generated under this Agreement on the basis of the reservation and commodity rates set forth in Paragraph 8(A) above, then Transporter
shall have the right to adjust (prospectively only) such reservation and/or commodity rates so as to enable Transporter to charge and collect the same level of revenues Transporter would have received as previously agreed between Transporter and Shipper.

C.	From time to time, dependent upon Transporter's Use percents, the MDQ's and MSQ under this Agreement, ETS Agreement 3200, ETS Agreement No. 102498 and FSS Agreement No. 34150 will be adjusted to allow Shipper to deliver and store
sufficient fuel quantities to effectuate a 50-day storage withdrawal quantity of 126,106 dth at the specified Delivery Points with no change in the total charges under these services.

D.	All quantities associated with Secondary Receipt Points, Secondary Delivery Points and Secondary Routes under this Agreement will be at Maximum Tariff Rates plus all other applicable fees, surcharges and fuel.

E.	Consistent with provisions of its Tariff, Transporter is willing to contract on Shipper's behalf for capacity required on third party transporters, or for other services to effectuate Shipper's receipt of gas on third party
facilities and delivery of gas to Transporter's facilities.

Shipper has advised Transporter of its desire to have Transporter act in such a capacity.

Shipper agrees to pay all charges related to such third party transportation arrangements pursuant to Transporter's Tariff.

F.	To the extent Shipper desires to utilize receipt/delivery points pursuant to Part 284 B (Section 311 of the NGPA and Section 284.102 of the Commission's regulations), Shipper must execute a separate agreement with Transporter and
Shipper must also certify that the transportation of gas will be on behalf of either an "intrastate pipeline" or a "local distribution company".

9.	OPERATIONAL FLOW ORDERS:

Shipper hereby guarantees to Transporter that each contract it has entered into in connection with the Gas to be transported under this Agreement contains a provision that permits Transporter to issue an effective Operational Flow
Order pursuant to Section 8 of the General Terms and Conditions, of Transporter's FERC Gas Tariff.



IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be signed by their respective Officers or Representatives there unto duly authorized to be effective as of the date stated above.
