Dear Mr. Minish:

The purpose of this letter is to set forth the understanding and agreement
between U.S. Energy Services, Inc. (U.S. Energy) and Western Plains Energy, LLC
(CUSTOMER) regarding the provision of energy management and engineering
services.

TERM - The initial term of this Agreement shall be from September 1, 2001
through August 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), or
         directly connecting with Alternative Pipeline (Pipeline) sources for
         facility sites under consideration. U.S. Energy will provide CUSTOMER
         with engineering cost estimates, route drawings, and a project timeline
         related to constructing pipeline facilities directly connecting
         CUSTOMER with PIPELINE.

         In the event that a direct connect pipeline option is selected, U.S.
         Energy will submit a tap request to PIPELINE. Engineering and
         construction management services related to constructing facilities
         that will interconnect with PIPELINE can be provided by U.S. Energy
         Services on a fee basis.

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

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

4.       Negotiate directly with PIPELINE, other shippers, and suppliers to
         provide transportation, balancing, and supply agreements that meet
         CUSTOMER'S performance criteria at the lowest possible cost.

5.       Provide daily nominations to PIPELINE and other applicable parties for
         CUSTOMER. This will include daily written confirmations to CUSTOMER of
         all nominations and actual daily usage. U.S. Energy will utilize
         telemetering to obtain actual usage on a real time basis.

6.       Provide advisory services to CUSTOMER 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 CUSTOMER.

7.       Prepare detailed cost estimates for substation, transformation and
         distribution equipment required for service options proposed by service
         providers.

8.       Prepare, implement and modify, as required, an electric and natural gas
         price risk management plan. The objective of the plan is to achieve
         stable forward prices that are consistent with CUSTOMER's risk profile
         and pricing objectives.

9.       U.S. Energy will also evaluate on an ongoing basis other options that
         may reduce energy costs.

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

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