                                   I. PARTIES

This contract is by and between the Southwest Water Authority, a governmental
entity created and existing pursuant to North Dakota Century Code chapter
61-24.5-03, hereinafter referred to as the Authority, the State Water
Commission, hereinafter referred to as the Commission; and Red Trail Energy LLC
hereinafter referred to as the Customer.

                                II. INTRODUCTION

1.   Under the authority of the Act of the North Dakota Legislative Assembly of
     1981 (1981 N.D. Sess. Laws 613, Section 3), the North Dakota State Water
     Commission (Commission) was directed to develop preliminary designs for a
     water supply pipeline facility for supplementation of the water resources
     of Dickinson and the area of North Dakota south and west of the Missouri
     River for multiple purpose, including domestic, industrial, rural water
     district, and municipal customers. This water pipeline facility is known as
     the Southwest Pipeline Project.

2.   The Southwest Pipeline Project was authorized by the North Dakota
     Legislative Assembly, substantially in accordance with Plan B of the
     Preliminary Engineering Design Final Report for the Southwest Pipeline
     Project, State Water Commission Project No. 1736, dated September 1982.

3.   The Southwest Pipeline Project was amended by the North Dakota Legislative
     Assembly in 1989 (Section 61-24.3-06-1, NDCC), from a water supply project
     to an integrated water supply, water distribution and water delivery
     project for cities and individual customers.

4.   The Legislative Assembly created the Southwest Water Authority in 1991
     (Chapter 61-24.5, NDCC), for the purpose of providing local operation,
     maintenance, and management of the Southwest Pipeline Project.

5.   In 1995, the State Water Commission entered into an agreement with the
     Authority whereby the completed portions of the Southwest Pipeline Project
     were transferred to the Authority for operation, maintenance and
     management.

6.   The Southwest Pipeline Project was amended by the North Dakota Legislative
     Assembly in 2005 (Section 61-24.3-07, NDCC), to allow expanded industrial
     use.

7.   Under North Dakota Century Code chapter 61-24.5-09 the Authority may enter
     into water service contracts for the delivery and distribution of water,
     and for the collection of rates, charges, and revenues from such delivery
     of water.

8.   The Customer desires to enter into a water service contract with the
     Authority, pursuant to the laws of the State of North Dakota, for a water
     supply from the Southwest Pipeline Project for use by the Customer, for
     which the Customer will make payments to the Authority at the rates and
     pursuant to the terms and conditions set forth in this contract.


                                                                    Page 3 of 14

1.   Quality of Raw Water.

     All water received pursuant to this contract, or any renewal, extension, or
     modification thereof, shall be raw untreated water which does not meet
     water quality standards of the North Dakota Department of Health and
     Consolidated Laboratories for domestic use.

1.A. Intended Use.

     Processing ethanol and by products produced therefrom.


                                                                    Page 5 of 14



2.   Type of Service.

     Constant flow not to exceed 600 gpm. Customer shall provide adequate on
     site storage to meet their processing needs.

3.   Quantity of Raw Water and Flow Rate.

     Minimum annual water purchase. The Customer agrees to purchase and make
     payment for not less than 200 million gallons per year (minimum annual raw
     water purchase) during the entire term of this contract (380 gpm). The
     Customer may purchase and make payment for water in excess of this amount
     as long as the Project's ability to meet other demands is not impaired.

     If, in the first year of service under this contract actual use begins
     later than January 1, the minimum annual raw water purchase shall be
     reduced by 16.7 million gallons for each full calendar month in which
     service was not provided. The full minimum annual raw water will be
     required in all subsequent years.

4.   Point of Delivery and Pressure.

     The Authority shall furnish raw water to the Customer at a pressure range
     of 40 psi to 55 psi at a point located at the Southwest Pipeline Project
     Contract 2-3A at the 30" ductile iron pipeline ten (10) inch turnout at
     Station 63+46 located in the NE 1/4 of Section 6, Township 139 North, Range
     92 West. If greater pressure than the range specified herein at the point
     of connection is required by the Customer, the cost of providing such
     greater pressure shall be borne by the Customer.

4.A. Customers Distribution System.

     The customers distribution system includes all works (service line, meter
     equipment, storage, appurtenances, etc.) extending from the point of
     delivery to the customers destination. Customer is responsible for all
     costs associated with installation of such works including O&M
     responsibilities for a minimum period of four (4) years after such works
     are put into service. At that time customer may have the option of
     transferring ownership and O&M responsibilities for all such work up to and
     including the meter equipment to the Commission. The customers remaining
     distribution system beyond the meter equipment including storage facilities
     shall remain the customers responsibility.

5.   Additional Raw Water.

     In addition to the minimum annual water purchase specified in Section V,
     subsection 3 of this contract, the Customer may purchase additional raw
     water. The Authority shall not be obligated in any way to supply raw water
     at a "greater" flow rate than the maximum flow rater specified in this
     contract. If the Customer desires to secure a contractual right to a
     greater maximum flow rate than specified in this contract, must be amended
     to provide a greater minimum annual raw water purchase, subject to Section


                                                                    Page 6 of 14



     VII, subsection 3 and 6.

6.   Water Shortages.

     a.   No liability for shortages. No liability shall against the Authority,
          the Commission, or any of its officers, agents, or employees for any
          damage or inconvenience, direct or indirect, arising from any water
          shortages or other interruptions in raw water deliveries resulting
          from accident to or failure of Project works and facilities, whether
          or not attributable to negligence of officers, agents, or employees of
          the Authority, or from any other cause. The contractual obligations of
          the Customer under this contract shall not be reduced or altered by
          reason of such shortages or interruptions.

     b.   Interruption of service during water shortages. The Authority has the
          right during times of water shortages, from any cause, to interrupt
          raw water service to serve customer with higher priority as referenced
          in Section VII, subsection 6.

7.   Curtailment for Maintenance Purposes.

     The Authority may temporarily discontinue or reduce the amount of raw water
     to be furnished for the purpose of maintaining, repairing, replacing,
     investigating or inspecting any of the facilities and works necessary for
     the furnishing of raw water. To the extent possible, the Authority will
     give reasonable notice in advance of any temporary discontinuance or
     reduction. No advance notice is required in case of an emergency. In no
     event shall any liability accrue against the Authority, the Commission, or
     any of its officers, agents, or employees for any damage or inconvenience
     direct or indirect, arising from such temporary discontinuance or reduction
     for maintenance and repair purposes.

8.   Measurement of Raw Water.

     The Customer shall furnish, install, operate and maintain, at its own
     expense, at the point of delivery, the necessary metering equipment and
     required devices of standard type for properly measuring the quantity of
     raw water delivered to the Customer. The Customer shall pay all costs of
     this equipment, easements, engineering services, contract administration
     and installation. Pipeline installations including all appurtenances will
     be in accordance with Southwest Pipeline Project specifications. The
     Authority, accompanied by an authorized Customer representative, shall be
     permitted access at all times to the master meter equipment, appurtenances,
     and associated equipment. The Customer will designate authorized
     representatives that can be made available to accompany the Authority
     representative upon short notice (four hours or less).

     If the Customer, in good faith, believes the measurement of raw water
     delivered to be in error, they shall present a claim of error, in writing,
     to the Manager/CEO, either in person or by certified mail to the address of
     the manager. A claim of error presented after a claim has become delinquent
     shall not prevent discontinuance of service as provided in this contract.
     The Customer agrees to continue to make payments for raw water service


                                                                    Page 7 of 14



     after a claim of error has been presented, however, the payment will be
     under protest and will not prejudice the Customer's claim of error.

     Upon presenting its claim of error and payment for the actual cost of
     calibration to the Authority, the Authority will calibrate the meter. If
     the meter is found to over register by more than two percent (2%) of the
     correct volume, the Customers payment for the cost of calibration will be
     refunded and the meter readings for that meter shall be corrected for the
     twelve (12) months previous to the calibration by the percentage of
     inaccuracy found in such tests. The amount of any overpayment as a result
     of over-registration shall be applied first to any delinquent payments for
     raw water service, and at the option of the Customer, any remaining amounts
     shall be refunded or credited upon future payments for raw water service in
     the ensuing years.

     If any meter fails to register for any period, the amount of raw water
     delivered during such period shall be deemed to be the amount of raw water
     delivered in the corresponding period immediately prior to the failure,
     unless the Authority and the Customer shall agree upon a different amount.
     The Customer and the Authority shall have access to the meter at all
     reasonable times for the purpose of verifying its readings.

9.   Responsibility of Use of Raw Water.

     The Customer shall be responsible for the control and use of all raw water
     beyond the point of connection and all services, maintenance, and repair of
     the Customer's distribution system. The Customer shall indemnify and hold
     the Authority, the Commission, its officers, agents, employees, and
     successors and assigns harmless from every claim for damage to persons or
     property, direct or indirect, and of whatever nature, arising out of or
     connected with the control, distribution, and use of raw water delivered
     under this contract, and the operation, maintenance, and replacement of the
     Customer's distribution system. The Customer's distribution system includes
     all works extending from the point of connection to the Customer's
     destination.

VI. RAW WATER SERVICE: RAW WATER RATES AND PAYMENT FOR RAW WATER

The Customer agrees to pay for raw water and raw water service in accordance
with the following terms and conditions:

1.   Notice of Connection and Beginning of Raw Water Service Payments.

     Upon approval, the Authority shall notify the Customer in writing of the
     date when the Customer may connect to the Project Transmission System. The
     Customer will make monthly payments for water and water service, beginning
     on the connection date specified in the notice.


                                                                    Page 8 of 14



1.A. Prepaid Payment.

     Prior to connection the Customer will deposit with the Authority a
     prepayment of $80,000. This deposit will be held in escrow until such time
     (minimum of three years) as it is determined that the Customer has
     established a consistent payment record. The Customer may be allowed to
     apply $40,000 toward its water bill at such time, however, the Authority
     may continue to retain $40,000 in escrow until end of this ten year
     contract. Upon renewal of the contract, the Customer may request the
     Authority to apply the remaining $40,000 or any part thereof to their water
     bill. Accrued interest, if any, will remain with the Authority.

2.   Payment for Raw Water Service.

     The Customer's water service payment for each month shall equal the sum of
     the following:

     a.   The Customer's proportionate share of the operation, maintenance, and
          replacement costs excluding the cost of treatment; plus

     b.   The Customer's payment for capital costs.

3.   Minimum Annual Raw Water Purchase; Payments.

     The Customer will pay for the minimum annual raw water purchase in
     accordance with the rates and terms specified in this contract, regardless
     of whether or not the Customer actually uses the minimum annual raw water
     purchase.

     If, by December, 31 of any year, the Customer has not used the minimum
     annual raw water purchase, payment for the difference between the minimum
     annual raw water purchase and the amount used shall be due.

4.   Payment for Operation, Maintenance, and Replacement (OM&R).

     The Customer will make monthly payments to the Authority for its share of
     the OM&R for the Project. The amount of such payment will be determined as
     follows:

     a.   Prior to February 1 of each year, the Authority shall establish and
          adopt a budget for OM&R for the Project for the immediate ensuing
          year. The Authority shall have the authority to include in such budget
          for each year an amount to be accumulated and maintained in a reserve
          fund for the purpose of replacement and for extraordinary maintenance
          of project works. The reserve fund shall be accumulated and maintained
          in an amount to be determined by the State Water Commission. The
          reserve fund shall be deposited and maintained in a separate account
          in accordance with the laws of the State of North Dakota.


                                                                    Page 9 of 14



     b.   The Authority will then estimate the total annual water sales for the
          immediate ensuing year, and calculate the "estimated water rate for
          operation, maintenance, and replacement" for the Project by dividing
          the amount of the estimated budget for OM&R for the immediate ensuing
          year by the estimated total annual water sales for such ensuing year.

     c.   The monthly payment to be made by the Customer to the Authority for
          OM&R shall be determined by multiplying the amount of water actually
          delivered to the Customer for each month times the estimated water
          rate for OM&R, excluding the cost of treatment.

     d.   At the end of each year, the Authority shall prepare a statement of
          the actual cost for OM&R for that same year.

     e.   The Authority will then determine the adjustment to be applied to the
          Customer's payment for OM&R for the previous year. The adjustment
          shall be calculated by first dividing the amount of water actually
          delivered to the Customer by the Authority during the previous year by
          the previous year's total annual water sales to determine the
          Customer's proportionate share (fraction) of the OM&R costs for the
          previous year. This fraction shall then be multiplied times the actual
          total cost for OM&R for the previous year, which shall be the amount
          of the Customer's proportionate share of OM&R costs for the previous
          year. The Authority shall then subtract the total amount of the
          Customer's proportionate share of OM&R costs for the previous year
          from the total amount actually paid by the Customer for OM&R during
          the previous year, which shall be the adjustment to be applied to the
          Customer's water service payments for the next ensuing year.

          If the Customer's proportionate share of OM&R costs for the previous
          year is more than the total amount actually paid by the Customer
          during the previous year for OM&R, the difference shall be owed by the
          Customer to the Authority. The amount due and owing to the Authority
          by the Customer as a result of such adjustment shall be applied to and
          added to the Customer's monthly payments for water for the next four
          (4) months of the immediate ensuing year in equal monthly
          installments.

          If the Customer's proportionate share of OM&R costs for the previous
          year is less than the total amount actually paid by the User during
          the previous delinquent payments of the Customer for water service,
          and the remaining sum, if any, shall be credited against the
          Customer's monthly payments for water service for the next four (4)
          months of the immediate ensuing year in equal monthly credits.

5.   Payment for Capital Costs.

     The Customer will pay to the Authority a water rate for capital costs of
     the Project. The revenues from this water rate for capital costs shall be
     paid by the Authority as directed by the Legislative Assembly.


                                                                   Page 10 of 14



     a.   Base water rate for capital costs. The base rate for capital costs for
          constant flow shall be seventy-two cents ($0.72) per each one thousand
          (1,000) gallons of water.

     b.   Adjustment of water rate for capital costs. The State Water Commission
          shall have the authority to adjust the water rate for capital costs
          annually in accordance with the increase or the decrease in the
          Consumer Price Index(CPI). The formula for determining the adjustment
          to the water rate for capital costs for each year is as follows: The
          CPI for September 1 of each year shall be divided by the base CPI of
          four hundred forty-eight and four tenths (448.4). The result of this
          calculation shall be reduced by one (1), and then multiplied by the
          base water rate for capital costs. The product of this formula is the
          adjustment to the water rate for capital costs, and shall be added to
          the base water rate for capital costs for the next year.
          Notwithstanding the foregoing basis for adjusting the water rate for
          capital costs, the Commission shall have the authority to decrease the
          adjustment to the water rate for capital costs, as it deems
          appropriate and necessary, after considering data on changes to the
          medial incomes of project water users, substantial increases in OM&R
          costs, or other factors.

     c.   Monthly water payment for capital costs. The amount of payment each
          month by the Customer to the Authority for capital costs shall be
          calculated by multiplying the water rate for capital costs times the
          amount of water actually delivered to the Customer each month.

6.   Billing Procedures.

     The metering equipment at the point of connection shall be read monthly,
     and the Authority will furnish, at the address shown on the signature page
     of this contract, not later than the first (1st) day of month, an itemized
     statement of the payment due for raw water service for the preceding month.

7.   When Payments Are Due.

     All payments for raw water service under this contract for OM&R, and for
     capital costs, shall be made no later than the fifteenth (15th) day of each
     month. Payments not made by such date shall be considered delinquent and in
     default.

8.   Delinquent Payments and Default: Suspension of Raw Water Service.

     The Customer shall meet its obligation under this contract, and will make
     in full, all payments required by this contract on or before the date such
     payments become due. In the event of default, the Authority, in its
     discretion, may suspend delivery of water through the project during the
     period of default. During any period of default, the Customer remains
     obligated to make all payments required under this contract. Any action of
     the Authority shall not limit or waive any remedy provided by the contract
     or by law for the recovery of money due or which may become due under this
     contract.


                                                                   Page 11 of 14



9.   Penalty for Late Payment.

     A penalty of one percent (1%) per month will be imposed upon all delinquent
     payments. Penalties will not be charged against any adjustment made
     pursuant to Section V, subsection 8.

10.  Refusal of Raw Water.

     The Customer's failure or refusal to accept delivery of water to which it
     is entitled under this contract will in no way relieve the Customer's
     obligation to make payments in accordance with this contract.

                            VII. GENERAL PROVISIONS

                                                                   Page 12 of 14



6.   Unallocated Capacity.

     The Customer understands and agrees that the Authority and the Commission
     will give preference to treated water for municipal, domestic, and rural
     water needs before executing raw water service contracts or allowing
     additional raw water purchases for the delivery of unallocated capacity to
     water customers for other uses.

                                VIII. TERMINATION

1.   By Mutual Agreement.

     This contract may be terminated by mutual agreement of the parties.

2.   For Misuse.

     This contract may be terminated upon discovery that the Customer has
     utilized raw water for domestic use or a use inconsistent with the terms of
     this contract. The Authority will be relieved of all obligations under this
     contract, and the Customer will be required to immediately disconnect his
     distribution system from the connection point.
