         7.0      MISCELLANEOUS

         7.1      ENTIRE AGREEMENT.

         This Agreement constitutes the entire Agreement between the parties
hereto regarding the Confidential Information disclosed thereunder and
supersedes all oral or written agreements,

<PAGE>

either entered prior to or contemporaneously with this Agreement, concerning
the Confidential Information. This Agreement may not be modified except by
written agreement dated subsequent to the date of this Agreement and signed
by both parties.

         7.2      ASSIGNMENT.

         Recipient shall not assign or transfer any rights or obligations
under this Agreement without the prior written consent of Discloser. Subject

         7.3      PRESUMPTIONS.

         In construing the terms of this Agreement, no presumption shall

         7.4      GOVERNING LAW.

         This Agreement shall be governed by and construed in accordance with
the laws of the State of South Dakota, excluding that body of law relating to

         7.5      SEVERABILITY; WAIVER.

         If any provision of this Agreement shall be held by a Court of
Competent Jurisdiction to be unenforceable, the remaining provisions shall
remain in full force and effect. A waiver by either of the parties hereto of
any of the covenants to be performed by the other party or any breach thereof
shall not be construed to be a waiver of any succeeding breach thereof or of
any covenant hereof contained.

         7.6      HOLD HARMLESS.

         The Recipient shall indemnify and save harmless the Discloser, its

any of the Terms and Conditions of this Agreement.

         7.7      REMEDIES.

         In the event the Recipient breaches or threatens to breach any of
the covenants expressed herein, the damage to the Discloser will be great and
irreparable and difficult to quantify; therefore, the Discloser may apply to
a Court of Competent Jurisdiction for injunctive or other equitable relief to
restrain such breach or threat of breach, without the necessity of filing any
bond, and without disentitling the Discloser from any other relief in either
law or equity.

<PAGE>

         IN WITNESS WHEREOF, the parties have executed this Agreement as of
the date first above written.

                                                                  Exhibit 10.11

                     [U.S. Energy Services, Inc. Letterhead]

February 6, 2001

Brian Manish
Great Plains Ethanol, LLC
P.O. Box 217
Lennox, SD  57039

Dear Mr. Manish:

The purpose of this letter is to set forth the understanding and agreement
between U.S. Energy Services, Inc. (U.S. Energy) and Great Plains Ethanol, LLC
(Great Plains Ethanol).

TERM: The initial term of this Agreement shall be from February 1, 2001 through
January 31, 2002, and thereafter for successive one year terms unless and until
terminated by either party with thirty (30) days notice.

U.S ENERGY SHALL:

1.       Provide a detailed economic comparison of receiving natural gas
         transportation service from a Local Distribution Company (LDC),
         intrastate pipeline or an interstate pipeline for facility sites under
         consideration. U.S. Energy will provide GREAT PLAINS ETHANOL with
         preliminary engineering cost estimates, route drawings, and project
         timeline related to constructing pipeline facilities directly
         connecting GREAT PLAINS ETHANOL with an intrastate or interstate
         pipeline.

         In the event that the direct connect pipeline option is selected, U.S.
         Energy will submit the tap request to the pipeline or utility.
         Engineering and construction management services related to
         constructing to NNG can be provided by U.S. Energy's sister company
         U.S. Energy Engineering, Inc. on a fee basis.

2.       Determine whether firm, interruptible, or a blend of transportation
         entitlement with NNG will provide the lowest burnertip cost for GREAT
         PLAINS ETHANOL. Factors that will be considered include pipeline
         credits for the new interconnect, cost of an alternate fuel system, and
         availability of specific receipt point capacity. Analysis of the costs
         and benefits will require U.S. Energy to negotiate as GREAT PLAINS
         ETHANOL's agent with NNG and other potential third party shippers.

3.       Provide natural gas supply information to minimize the cost of natural
         gas purchased by GREAT PLAINS ETHANOL. This will include acquiring
         multiple supply quotes and reporting to GREAT PLAINS ETHANOL the
         various supply index and fixed prices. U.S. Energy will not take title
         to GREAT PLAINS ETHANOL gas supplies, but will communicate supply
         prices and potential buying strategies.

4.       Negotiate directly with pipelines, utilities, other shippers, and
         suppliers to provide transportation, balancing, and supply agreements
         that meet GREAT PLAINS ETHANOL's performance criteria at the lowest
         possible cost.

5.       Provide daily nominations to the pipeline, utility, other applicable
         shippers, and suppliers for GREAT PLAINS ETHANOL. This will include
         daily written confirmations to GREAT PLAINS ETHANOL of all nominations
         and actual daily usage. U.S. Energy will utilize customer or utility
         supplied telemetering to obtain actual usage on a real time basis.

6.       Provide advisory services to GREAT PLAINS ETHANOL regarding electric
