8. FURTHER AGREEMENT:

1. The rate for the Primary Route MDQ as listed in the attached Primary Route Exhibit and secondary receipts/deliveries as listed below shall be a Monthly Reservation Rate of $2.8140 per dth and the applicable Commodity Rate (equivalent on a daily basis to a 100% Load Factor Rate of $0.1000 per dth). This rate shall be inclusive of Dakota Surcharge, Transition Costs, and any other fees or surcharges under Transporter's FERC Gas Tariff, not to exceed the total of Transporter's Maximum Reservation, Commodity and applicable surcharge rates. In addition, Shipper shall be charged ACA and Transporter's Use (Fuel) in accordance with Transporter's FERC Gas Tariff. Shipper shall not be charged for GRI surcharges, unless and to the extent that Transporter is required to collect and/or remit such charges to GRI.

Date: March 20, 2003 Contract No.: 109014

3. In addition, if one rate component which was at or below the applicable Maximum Rate at the time this discount agreement was executed subsequently exceeds the applicable Maximum Rate due to a change in Transporter's Maximum Rates so that such rate component must be adjusted downward to equal the new applicable Maximum Rate, then other rate components may be adjusted upward to achieve the agreed overall rate, as long as none of the resulting rate components exceeds the Maximum Rate applicable to that rate component. Such changes to rate components shall be applied prospectively, commencing with the date a Commission Order accepts revised tariff sheet rates. However, nothing contained herein shall be construed to alter a refund obligation under applicable law for any period during which rates that had been charged under a discount agreement exceeded rates, which ultimately are found to be just and reasonable.
4. Shipper shall be entitled to the Right of First Refusal provided for in Section 22 of the General Terms and Conditions of Transporter's FERC Gas Tariff, notwithstanding the fact that Shipper would otherwise be ineligible for this right under Section 22.2.

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