Changes in Rates and Terms: Transporter shall have the right to propose to the FERC changes in its rates and terms of service, and this Agreement shall be deemed to include any changes which are made effective pursuant to FERC Order or regulation or provisions of law, without prejudice to Shipper's right to protest the same.

14.

Governing Law. Transporter and Shipper expressly agree that the laws of the State of Colorado shall govern the validity, construction, interpretation, and effect of this Agreement and of the applicable Tariff provisions. This Agreement is subject to all applicable rules, regulations, or orders issued by any court or regulatory agency with proper jurisdiction.

15.

Construction of Facilities. The parties recognize that Transporter must construct additional facilities in order to provide transportation service for Shipper under this Agreement. Transporter's obligations under this Agreement are subject to: Shipper providing evidence of creditworthiness in a manner satisfactory to Transporter equal to at least one year of Shipper's reservation and commodity charges under the Agreement (satisfactory evidence of creditworthiness may include a Letter of Credit, a guarantee from a creditworthy party, or a satisfactory review of the financial status of the Shipper by Transporter). The one-year requirement shall remain in effect until Transporter has been reimbursed for the cost of the facilities or this Agreement terminates, whichever occurs sooner.

16.

Sharing of Interruptible and Short Term Firm Transportation Revenue and Authorized Overrun Charges. Under this negotiated rate agreement, Shipper shall receive fifty percent (50%) of a pro rata share of the revenues received by Transporter from Interruptible and Short-Term Firm Transportation Services (net of variable costs and surcharges) until such time as the FERC modifies the treatment of the costs and revenues of such service. In addition, Shipper shall receive fifty percent (50%) of a pro rata share of any Authorized Overrun charges collected by Transporter (net of variable costs and surcharges) until such time as the FERC modifies the treatment of Authorized Overrun Charges. Shipper's pro rata share shall be determined and paid annually and shall be based upon the relationship of the total payments received by Transporter from the Shipper and the total revenues received by the Transporter.

17.

Most-favored Nations Rate Provision. From October 18, 2002 through the term of this Agreement, if a future shipper on an expansion of the Pipeline executes a transportation service agreement for service from the Cheyenne to the Greensburg area for the same length of service

or shorter that has a negotiated or discounted rate that is lower on a 100 percent load factor basis than the negotiated rate contained herein, then the rate established in this Agreement shall be reduced to the same level as such other comparable negotiated or discounted rate. Rates for services using capacity release, discounts granted to Secondary Points, or rates resulting from the exercise of a ROFR right will not trigger this most favored nation provision.

18.

Execution of Replacement Agreement. In the event the Pro Forma Transportation Service Agreement approved by the FERC as part of the Tariff of the Cheyenne Plains Pipeline varies in form from this Agreement, the Parties agree to execute a replacement agreement in the form of the pro forma agreement in the Tariff. Any substantive difference between this Agreement and the approved pro forma agreement, which remains in effect at the time the replacement agreement is prepared shall be reflected in the replacement agreement.

        IN WITNESS WHEREOF, the parties hereto have executed this Agreement.

NOTES:

Information regarding receipt point(s) and delivery point(s), including legal descriptions, measuring Parties, and interconnecting Parties, shall be posted on Transporter's Electronic Bulletin Board. Transporter shall update such information from time to time to include additions, deletions, or any other revisions deemed appropriate by Transporter.

(2)

Each receipt point quantity may be increased by an amount equal to Transporter's Fuel Reimbursement percentage. Shipper shall be responsible for providing such Fuel Reimbursement at each receipt point on a pro rata basis based on the quantities received on any Day at a receipt point divided by the total quantity delivered at all delivery point(s) under this Transportation Service Agreement.

(3)

The sum of the delivery quantities at delivery point(s) shall be equal to Shipper's MDQ.

(4)

Cheyenne Plains shall install delivery facilities to Southern Star with meter capacities capable of flowing 560 MDth provided the delivery pressure equals or exceeds 810 p.s.i.g. (recognizing that the current take-away capacity at the proposed point of interconnection with Southern Star is approximately 400 MDth per Day). Cheyenne Plains shall install delivery facilities to ANR, PEPL, NNG and NGPL with meter capacities capable of flowing the lesser of (i) the maximum deliverability of the Cheyenne Plains pipeline at the point of interconnection, or (ii) the current take-away capacity at the point of interconnection, or (iii) 1000 MDth (provided the delivery pressure equals or exceeds 810 p.s.i.g.).

NOTES:

(1)

Shipper shall pay negotiated reservation rates of $10.3417 per month. (The monthly reservation charge is equivalent to a rate of $0.34 per Dth per day on a 100% load factor basis.) Under the negotiated rates, there will be no commodity or usage charge, unless Transporter is required by the FERC to assess such a commodity charge, in which event the commodity charge shall be set at the minimum permissible level, and the reservation rate described above shall be reduced to a level that causes the combined commodity and reservation rates to equal a 100% load factor rate of $0.34. Should the FERC or a court with jurisdiction issue a ruling that has the effect of prohibiting Transporter from collecting, or penalizing Transporter for collecting the rates and revenues provided for herein, then the parties agree to enter into a substitute lawful arrangement, such that the parties are placed in the same economic position as if Transporter had collected such rates. The negotiated rate shall be applicable to revised primary receipt or delivery points, and Transporter shall agree to all requests for changes to primary receipt or delivery point changes if capacity is available at such points and the change can be made without adversely affecting system operations or other firm obligations.

(2)

From the first day the Pipeline is ready to free flow gas until the first day of the month following the date the Pipeline is fully operational, no fuel will be consumed in pipeline operations. Accordingly, during such period the fuel reimbursement shall be limited to a collection of lost and unaccounted for gas. Following the first day of the month following the date the Cheyenne Plains Pipeline is fully operational Fuel Reimbursement shall be as stated on Transporter's Statement of Rates sheet in the Tariff, as they may be changed from time to time, unless otherwise agreed between the Parties.

(3)

Surcharges, if applicable: All applicable surcharges, unless otherwise specified, shall be the maximum surcharge rate as stated on the Statement of Rates sheet, as they may be changed from time to time, unless otherwise agreed to by the Parties.
