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
         pricing and service agreements. Such services will include, but are not
         limited to, the following:

                  a.       Evaluation of regulatory and legislative precedent
                           regarding electric supplier choice options.
                  b.       Identification of qualified electric suppliers.
                  c.       Evaluation of self-generation options.
                  d.       Development and implementation of an electric
                           sourcing strategic plan. Such plan may include a
                           competitive bid process and/or installation of
                           on-site generation.
                  e.       Negotiation of electric service agreements that meet
                           the pricing and reliability requirements of GREAT
                           PLAINS ETHANOL.

7.       U.S. Energy will also evaluate other options that may reduce energy
         costs. Such options include, but are not limited to joint projects with
         other energy users in the area.

8.       Provide a monthly projection of energy (natural gas and electricity)
         and annual summaries.

9.       Provide a consolidated monthly invoice that reflects all applicable
         costs. U.S. Energy will be responsible for reconciling and paying all
         shipper and supplier invoices.

FEES: U.S. Energy's fee for services described in items 1-9 during the initial
term of this agreement shall be $1,950 per month, plus pre-approved travel
expenses not to exceed $2,500 during the initial term of this agreement. The
monthly retainer and out of pocket expenses will begin to accrue on the
commencement date of this Agreement. GREAT PLAINS ETHANOL will not be invoiced
until financing for the plant has been secured. In the event that plant
financing is not secured, this Agreement shall become null and void and both
parties will be relieved of professional and/or financial obligations due the
other party.

TERMINATION: GREAT PLAINS ETHANOL shall have the unilateral right to terminate
this Agreement, with or without cause, at any time during the initial term and
any subsequent term of the Agreement with thirty (30) days written notification
if not satisfied with U.S. Energy's service.

BILLING AND PAYMENT: On the first of the month, U.S. Energy shall invoice GREAT
PLAINS ETHANOL. GREAT PLAINS ETHANOL shall pay U.S. Energy within ten (10) days
of receipt of invoice.
