                                LETTER OF INTENT

Date:     March 24, 2005

Parties:  Fagen, Inc., a Minnesota Corporation, of Granite Falls, MN ("Fagen")
          and Advanced BioEnergy, LLC, a Delaware limited liability company
          ("Owner")

WHEREAS, Owner is an entity organized to facilitate the development and
building of a 100 MGY gas-fired fuel ethanol plant near Fairmont, Nebraska (the
"Facility" or "Project");

WHEREAS, Fagen is an engineering and construction firm capable of providing
development assistance, as well as designing and constructing the Facility being
considered by Owner; and

WHEREAS, this Letter of Intent supercedes and replaces any prior Letter of
Intent between Fagen and Owner relating to the Project.

NOW, THEREFORE, in consideration of the promises and mutual covenants set forth
herein, Owner and Fagen agree to use best efforts in jointly developing this
Project under the following terms:

               1. Owner agrees that Fagen will design-build the Facility if
          determined by Owner to be feasible and if adequate, financing is
          obtained. Should Owner choose to develop or pursue a relationship with
          a company other than Fagen to provide the preliminary engineering or
          design-build services for the project, then Owner shall reimburse
          Fagen for all expenses Fagen has incurred in connection with the
          Project based upon Fagen's standard rate schedule plus all third party
          costs incurred from the date of this Letter of Intent. Such expenses
          include, but are not limited to, labor rates and reimbursable expenses
          such as legal charges for document review and preparation, travel
          expenses, reproduction costs, long distance phone cost, and postage.
          In the event Fagen's services are terminated by Owner, title to the
          technical data, which may include preliminary engineering drawings and
          layouts and proprietary process related information, shall remain with
          Fagen; however, Owner shall, upon payment of the foregoing expenses,
          have the limited license to use the above described technical data,
          excluding proprietary process related information, for construction,
          operation, repair and maintenance of the Project.

               If Fagen intentionally or by gross negligence fails or refuses to
          comply with its commitments contained in this Letter of Intent, Fagen
          shall absorb all of its own expenses, and Owner shall have the right
          to terminate the Letter of Intent immediately upon written notice to
          Fagen, and Owner shall be released from its obligations to pay or
          reimburse Fagen as described above.

          2.   Fagen will provide Owner with assistance in evaluating, from both
     a technical and business perspective:

               -    Owner organizational options;
               -    The appropriate location of the proposed Facility; and
               -    Business plan development.

     Fagen assumes no risk or liability of representation or advice to Owner by
     assisting in evaluating the above. All decisions made regarding
     feasibility, financing, and business risks are the Owner's responsibility
     and liability.

          3.   Fagen agrees to design-build the Facility, utilizing ICM, Inc.
     technology in the plant process, for a lump sum price of $98,000,000.00.
     This lump sum price shall remain firm by Fagen to Owner until December 31,
     2005, and may be subject to revision by Fagen after such date.

          4.   Fagen will. assist Owner in locating appropriate management for
     the Facility.

          5.   Fagen will assist Owner in presenting information to potential
     investors, potential lenders, and various entities or agencies that may
     provide project development assistance.

          6.   During the term of this Letter of Intent the Owner agrees that
     Fagen will be the exclusive Developer and Design-Builder for the Owner in
     connection with matters covered by this Letter of Intent, and Owner shall
     not disclose any information related to this Letter of Intent to a
     competitor or prospective competitor of Fagen.

          7.   This Letter of Intent shall terminate on December 31, 2005 unless
     the basic size and design of the Facility have been determined and mutually
     agreed upon, and a specific site or sites have been determined and mutually
     agreed upon, and at least 10% of the necessary equity has been raised.
     Furthermore, this Letter of Intent shall terminate on December 31, 2006
     unless financing for the Facility has been secured. Either of the
     aforementioned dates may be extended upon mutual written agreement of the
     Parties.

          8.   Fagen and Owner agree to negotiate in good faith and enter into a
     definitive lump sum design-build agreement, including Exhibits thereto,
     acceptable to the Parties. Upon execution of such agreement, this Letter of
     Intent becomes null and void.

          9.   The Parties will jointly agree on the timing and content of any
     public disclosure, including, but not limited to, press releases, relating
     to Fagen's involvement in Owner's Project, and no such disclosure shall be
     made without mutual consent and approval, except as may be required by
     applicable law.

     by written agreement by the Parties.

          11.  This Letter of Intent may be executed in one or more
     counterparts, each of which when so executed and delivered shall be deemed
     an original, but all of which taken together constitute one and the same
     instrument. Signatures which have been affixed and transmitted by facsimile

                       ADDITIONAL SERVICES OF TRANSYSTEMS

     SECTION 2.1.   ADDITIONAL SERVICES. In connection with the Project,
TRANSYSTEMS may be called on to perform, provide, furnish or obtain from others
services or work which are not part of, or are in addition to, the Basic
Services ("Additional Services"). If authorized in writing by CLIENT and agreed

the parties to keep changes in the Scope of Services at a minimum, but the
parties recognize that such changes may become necessary and agree that CLIENT
may initiate deletions, modifications or changes to the Services by advising
TRANSYSTEMS in writing of the change believed to be necessary. As soon
thereafter as practicable, TRANSYSTEMS shall prepare a cost estimate of the
change and shall inform CLIENT of the adjustment in the compensation due
TRANSYSTEMS under Section 5 hereof ("TRANSYSTEMS' Compensation") and/or the
Completion Date set forth in Section 4 hereof, if any, applicable to such

contract amendment shall be executed by both parties and TRANSYSTEMS shall
perform the Services as changed and the adjustment in TRANSYSTEMS' Compensation
and/or the Completion Date set forth in the executed contract amendment shall
become effective. TRANSYSTEMS may initiate changes in the Services by advising
CLIENT in writing that in its opinion a change is necessary. If CLIENT approves,
it shall so advise TRANSYSTEMS and, thereafter, the change shall be handled as
if initiated by CLIENT. If a change is not approved, or if a written contract
amendment is not executed, by both CLIENT and TRANSYSTEMS, the change shall not
become effective and TRANSYSTEMS shall not be obligated to perform the change.

     Client shall do the following in a timely manner so as not to delay the
performance of the Services by TRANSYSTEMS:

     SECTION 3.1    CLIENT REPRESENTATIVE. Designate a person to act as Client's
representative with respect to the Services to be rendered under this Agreement.
Such person shall have complete authority to transmit instructions, receive
information, interpret, and define CLIENT'S policies and decisions with respect
to TRANSYSTEMS' Services for the Project.

     SECTION 3.2    PROJECT INFORMATION. Provide all criteria, all available

provisions for TRANSYSTEMS to enter upon public and private property as required
for TRANSYSTEMS to perform services under this Agreement. All such access shall
be provided without condition or restriction unacceptable to TRANSYSTEMS nor
shall TRANSYSTEMS be required to indemnify or insure any third party as a
condition to such access.

     SECTION 3.4    CLIENT PARTICIPATION. Examine all studies, reports,
sketches, drawings, specification, proposals, and other documents presented by
TRANSYSTEMS, obtain advice of an attorney, insurance counselor and other
CONSULTANT as CLIENT deems appropriate for such examination and render in
writing decisions pertaining thereto within a reasonable time so as not to delay
the services of TRANSYSTEMS.

     SECTION 3.5    NOTICES. Give prompt written notice to TRANSYSTEMS whenever
CLIENT observes or other wise becomes aware of any development that affects the
scope or timing of TRANSYSTEMS' Services, or any defect or non-conformance in

CONSULTANTS) or in the work of any contractor or other party performing or
providing work or services in connection with the Project.

     SECTION 3.6    ADDITIONAL SERVICES. When CLIENT deems it necessary or
appropriate for Additional Services to be performed in connection with any phase

necessary governmental allocations or priorities, obtain all permits and
licenses required to be taken out in the name of CLIENT which are necessary for
the performance of the Services and, except where such permits, processes or
licenses are by the terms of Exhibit A the responsibility of TRANSYSTEMS, obtain
any permits, processes and other licenses which are required for the Project or
the Services.

identified on Exhibit B, if any.

     SECTION 3.9    DEFECTS IN SERVICES. The Client shall promptly report to
TRANSYSTEMS any defects or suspected defects in TRANSYSTEMS' services of which
the Client becomes aware, so that TRANSYSTEMS may take measures to minimize the

notification requirement on all contractors in its Client/Contractor contract
and shall require all subcontracts at any level to contain a like requirement.
Failure by the Client and the Client's contractors or subcontractors to notify
TRANSYSTEMS shall relieve TRANSYSTEMS of the costs of remedying the defects
above the sum such remedy would have cost had prompt notification been given
when such defects were first discovered.

to have their CGL policies endorsed to name the Client, TRANSYSTEMS and its
subconsultants as Additional Insureds and to provide Contractual Liability
coverage sufficient to insure the hold harmless and indemnity obligations
assumed by the contractors. The Client shall require all contractors to furnish
to the Client and TRANSYSTEMS certificates of insurance as evidence of the
required insurance prior to commencing work and upon renewal of each policy
during the entire period of construction. In addition, the Client shall require
that all contractors will, to the fullest extent permitted by law, indemnify and
hold harmless the Client, TRANSYSTEMS and its subconsultants from and against
any damages, liabilities or costs, including reasonable attorneys' fees and
defense costs, arising out of or in any way connected with the Project,
including all claims by employees of the contractors.

     SECTION 3.12   UNAUTHORIZED CHANGES. In the event the Client, the Client's
contractors or subcontractors, or anyone for whom the Client is legally liable
makes or permits to be made any changes to any reports, plans, specifications or
other construction documents prepared by TRANSYSTEMS without obtaining
TRANSYSTEMS's prior written consent, the Client shall assume full responsibility
for the results of such changes. therefore the Client agrees to waive any claim
against TRANSYSTEMS and to release TRANSYSTEMS from any liability arising
directly or indirectly from such changes.

     In addition, the Client agrees, to the fullest extent permitted by law, to
indemnify and hold harmless TRANSYSTEMS from any damages, liabilities or costs,
including reasonable attorneys' fees and costs of defense, arising from such
changes.

     In addition, the Client agrees to include in any contracts for construction
appropriate language that prohibits the Contractor or any subcontractors of any
tier from making any changes or modifications to TRANSYSTEMS' construction
documents without the prior written approval of TRANSYSTEMS and that further
requires the Contractor to indemnify both TRANSYSTEMS and the Client from any
liability or cost arising from such changes made without such proper
authorization.

construction manager, the Client will promptly notify TRANSYSTEMS of the duties,
responsibilities and authority of the construction manager and their
relationship to the duties, responsibilities and authority of TRANSYSTEMS.

     If the employment of such construction manager by the Client results in
additional time or expense to TRANSYSTEMS to prepare for, coordinate with or
respond to the construction manager, TRANSYSTEMS shall be entitled to an
equitable adjustment in fees and time for performance of these services.

     SECTION 3.14   COSTS. Bear all costs incident to compliance with the
requirements of this Section 3.

make any payment due TRANSYSTEMS for services and expenses within thirty (30)
days after receipt of TRANSYSTEMS' statement therefor, TRANSYSTEMS shall be
entitled interest on the unpaid amounts due TRANSYSTEMS at the lesser of: i) 1.5
% per month; or, ii) the highest rate of interest allowed under applicable law.
The entire unpaid balance due TRANSYSTEMS shall bear said rate of interest from
the thirtieth day after CLIENT's receipt of TRANSYSTEMS' statement, until the
entire unpaid balance has been paid to TRANSYSTEMS. In addition to being
entitled to interest, TRANSYSTEMS may, after giving seven (7) days written
notice to CLIENT, suspend services under this Agreement until TRANSYSTEMS has
been paid in full all amounts due for Services, expenses, and charges.

          SECTION 5.5.2 PAYMENTS AFTER TERMINATION BY CLIENT. In the event of
termination by CLIENT under paragraph 7.1 upon the completion of any phase of
the Basic Services, payments due TRANSYSTEMS for all Services rendered and
expenses incurred through such phase shall constitute total payment for such
Basic Services. In the event of such termination by CLIENT during any phase of
the Basic Services, TRANSYSTEMS will be paid for Services rendered and expenses
incurred during that phase through the date of termination on the basis of
TRANSYSTEMS' Schedule of Rates and Expenses. In the event of any such
termination (whether at the completion of a phase or otherwise), TRANSYSTEMS
shall also be reimbursed for the charges of independent professional associates
and CONSULTANTS employed by TRANSYSTEMS to render Basic Services or Additional
Services and all reasonable demobilization costs incurred by TRANSYSTEMS,
including any cancellation charges by independent professional associates,
CONSULTANTS and others performing or furnishing Services on the Project through
TRANSYSTEMS, and TRANSYSTEMS shall be paid for all Additional Services performed
and unpaid Reimbursable Expenses incurred through the date of the termination.

          SECTION 5.5.3 PAYMENTS AFTER TERMINATION BY TRANSYSTEMS. In the event
of termination by TRANSYSTEMS under paragraph 7.1, TRANSYSTEMS will be paid for
all Services rendered and expenses incurred during that phase through the date
of termination on the basis of TRANSYSTEMS' Schedule of Rates and Expenses. In
addition, TRANSYSTEMS shall also be reimbursed for the charges of independent
professional associates and CONSULTANTS employed by TRANSYSTEMS to render Basic
Services or Additional Services and all reasonable demobilization costs incurred
by TRANSYSTEMS, including any cancellation charges by independent professional
associates, CONSULTANTS and others performing or furnishing Services on the
Project through TRANSYSTEMS, and TRANSYSTEMS shall be paid for all Additional
Services performed and unpaid Reimbursable Expenses incurred through the date of

          SECTION 5.5.4 RECORDS. Records of TRANSYSTEMS' salary costs pertinent
to TRANSYSTEMS' compensation under this Agreement will be kept in accordance
with generally accepted accounting practices. If Client desires to have copies
of such records, copies will be made available to CLIENT upon Client's request
prior to final payment for TRANSYSTEMS' services. TRANSYSTEMS shall be
reimbursed the cost of any such copies by CLIENT.

          SECTION 5.5.5 COST FACTORS. Whenever a factor is applied to salary
costs or other expenses in determining compensation payable to TRANSYSTEMS that
factor will be adjusted periodically and equitably to reflect changes in the
various elements that comprise such factor. All such adjustments will be in
accordance with generally accepted accounting practices as applied on a
consistent basis by TRANSYSTEMS and consistent with TRANSYSTEMS' overall
compensation practices and procedures.

                                    SECTION 6
                          OPINIONS OF COST AND SCHEDULE

     SECTION 6.1    OPINIONS OF COST AND SCHEDULE. Since TRANSYSTEMS has no
control over the cost of labor, materials, equipment or services furnished by
others, or over the resources provided by others to meet construction or other
Project schedules, or over the methods of others in determining prices, or over
competitive bidding or market conditions, TRANSYSTEMS' opinions of probable
costs (including probable Total Project Costs and Construction Cost) and of
Project schedules shall be made on the basis of TRANSYSTEMS' experience and
qualifications and represent TRANSYSTEMS' best judgment as an experienced and
qualified professional engineer, familiar with the construction industry; but
TRANSYSTEMS cannot and does not guarantee that proposals, bids or actual Project
costs (including Total Project Costs or Construction Costs) will not vary from
opinions of probable cost prepared by TRANSYSTEMS or that actual schedules will
not vary from the projected schedules prepared by TRANSYSTEMS. TRANSYSTEMS makes
no warranty, express or implied, that the bids or the negotiated cost of the
work will not vary from TranSystems' opinion of probable construction cost.

                                    SECTION 7
                             GENERAL CONSIDERATIONS

     SECTION 7.1    TERMINATION. The obligation to provide further services
under this Agreement may be terminated by either party upon thirty (30) days
written notice to the other party in the event of substantial failure by the
other party to perform in accordance with the terms hereof through no fault of
the terminating party.

          SECTION 7.1.1 REPLACEMENT OF TRANSYSTEMS. If TRANSYSTEMS for any
reason is not allowed to complete all the services called for by this Agreement,
TRANSYSTEMS shall not be held responsible for the accuracy, completeness or
constructability of the construction documents prepared by TRANSYSTEMS if used,
changed or completed by the Client or by another party. Accordingly, the Client
agrees, to the fullest extent permitted by law, to indemnify and hold harmless
TRANSYSTEMS, its officers, directors, employees and subconsultants
(collectively, TRANSYSTEMS) from any damages, liabilities or costs, including
reasonable attorneys' fees and defense costs, arising or allegedly arising from
such use, change or completion by any other party of any construction documents
prepared by TRANSYSTEMS.

     SECTION 7.2    REUSE OF DOCUMENTS. All documents, drawings, sketches,
studies, analysis, information, schedules, estimates, reports and other items
prepared or furnished by TRANSYSTEMS (or TRANSYSTEMS' independent professional
associates and CONSULTANTS) pursuant to this Agreement, including, but not
limited to Drawings and Specifications, are instruments of service in respect of
the Project and TRANSYSTEMS shall retain an ownership and property interest
therein whether or not the Project is completed. Provided, however, that such
documents, drawings, sketches, studies, analysis, information, schedules,
estimates, reports and other items are not intended or represented to be
suitable for reuse by CLIENT or others on extensions of the Project or on any
other project. Any reuse without written verification or adaptation by
TRANSYSTEMS for the specific purpose intended will be at CLIENT's sole risk and
without liability or legal exposure to TRANSYSTEMS, or to TRANSYSTEMS'
independent professional associates or CONSULTANTS, and CLIENT does hereby, to
the fullest extent permitted by law, indemnify and hold harmless TRANSYSTEMS,
TRANSYSTEMS' officers, employees and agents and TRANSYSTEMS' independent
professional associates and CONSULTANTS from all claims, suits, demands,
damages, liabilities, losses, expenses and costs, including but not limited to
reasonable attorney's fees and other costs of defense, arising out of or
resulting therefrom. The provisions of this Section 7.2 shall survive the
termination of this Agreement.

     SECTION 7.3    DELIVERY OF ELECTRONIC FILES. In the event that Client
requests any electronic deliverables under this agreement, TRANSYSTEMS and
Client shall execute a separate CADD agreement. Otherwise, in accepting and
utilizing any drawings, reports and data on any form of electronic media
generated and furnished by TRANSYSTEMS, the Client agrees that all such
electronic files are instruments of service of TRANSYSTEMS, who shall be deemed
the author, and shall retain all common law, statutory law and other rights,
including copyrights.

     The Client agrees not to reuse these electronic files, in whole or in part,
for any purpose other than for the Project. The Client agrees not to transfer
these electronic files to others without the prior written consent of
TRANSYSTEMS. The Client further agrees to waive all claims against TRANSYSTEMS
resulting in any way from any unauthorized changes to or reuse of the electronic
files for any other project by anyone other than TRANSYSTEMS.

Advanced Bio Energy
Revised  January 7, 2005                12
<Page>

     Electronic files furnished by either party shall be subject to an
acceptance period of sixty (60) days during which the receiving party agrees to
perform appropriate acceptance tests. The party furnishing the electronic file
shall correct any discrepancies or errors detected and reported within the
acceptance period. After the acceptance period, the electronic files shall be
deemed to be accepted and neither party shall have any obligation to correct
errors or maintain electronic files.

     The Client is aware that differences may exist between the electronic files
delivered and the printed hard-copy construction documents. In the event of a
conflict between the signed construction documents prepared by TRANSYSTEMS and
electronic files, the signed or sealed hard-copy construction documents shall
govern.

     In addition, the Client agrees, to the fullest extent permitted by law, to
indemnify and hold harmless TRANSYSTEMS, its officers, directors, employees and
subconsultants (collectively, TRANSYSTEMS) against all damages, liabilities or
costs, including reasonable attorneys' fees and defense costs, arising from any
changes made by anyone other than TRANSYSTEMS or from any reuse of the
electronic files without the prior written consent of TRANSYSTEMS.

     Under no circumstances shall delivery of electronic files for use by the
Client be deemed a sale by TRANSYSTEMS, and TRANSYSTEMS makes no warranties,
either express or implied, of merchantability and fitness for any particular
purpose. In no event shall TRANSYSTEMS be liable for indirect or consequential
damages as a result of the Client's use or reuse of the electronic files.

     SECTION 7.4    STANDARD OF PRACTICE, WARRANTIES. Services performed by the
TRANSYSTEMS under this Agreement will be conducted in a manner consistent with
the level of care, diligence and skill ordinarily possessed and exercised by
members of the profession currently practicing in the same locality under
similar conditions. Except as expressly set forth above, no other
representations, expressed or implied, and no warranty or guarantee, express or
implied, is included in this Agreement, or in any document, drawing, sketch,
study, analysis, schedule, estimate, report, opinion, specification and other
item prepared or furnished by TRANSYSTEMS (or TRANSYSTEMS' independent
professional associates and TRANSYSTEMSs) pursuant to this Agreement.

     SECTION 7.5    LIMITATION OF RESPONSIBILITY, JOB SITE SAFETY/TECHNIQUES.
Neither the professional activities of TRANSYSTEMS, nor the presence of
TRANSYSTEMS or its employees and subconsultants at a construction/project site,
shall relieve the General Contractor of its obligations, duties and
responsibilities including, but not limited to, construction means, methods,
sequence, techniques or procedures necessary for performing, superintending and
coordinating the Work in accordance with the contract documents and any health
or safety precautions required by any regulatory agencies. TRANSYSTEMS and its
personnel have no authority to exercise any control over any construction
contractor or its employees in connection with their work or any health or
safety programs or procedures. The Client agrees that the General Contractor
shall be solely responsible for jobsite safety, and warrants that this intent
shall be carried out in the Client's contract with the General Contractor. The
Client also agrees that the Client, TRANSYSTEMS and the

contractual responsibilities and obligations to client or to comply with
Federal, State or local laws, rules, regulations or codes; (ii) for the
schedules of any of the other project parties or the failure of any of the other

                   SPECIAL PROVISIONS, EXHIBITS AND SCHEDULES

     SECTION 8.1    SPECIAL PROVISIONS. THIS AGREEMENT IS SUBJECT TO NO SPECIAL
                    PROVISIONS. ALL TERMS ARE IDENTIFIED IN THE CONTRACT AND THE
                    ATTACHED PROPOSAL LETTER.

     SECTION 8.2    CONTRACT DOCUMENTS. This Agreement consists of this contract
document and the following Exhibits and Schedules, which are attached to and
made a part of this Agreement:

     Exhibit A - Project Description and Basic Services
     Exhibit B - TRANSYSTEMS' Schedule of Rates and Expenses

     SECTION 8.3    ENTIRE AGREEMENT. This Agreement together with the Exhibits
and Schedules identified above constitute the entire agreement between CLIENT
and TRANSYSTEMS and supersede all prior written or oral understandings. This
Agreement and said Exhibits and Schedules may only be amended, supplemented,
modified, or canceled by a duly executed written instrument.

     Nothing contained in this Agreement shall create a contractual relationship
with or a cause of action in favor of a third party against either the Client or
TRANSYSTEMS. TRANSYSTEMS' services under this Agreement are being performed
solely for the Client's benefit, and no other party or entity shall have any
claim against TRANSYSTEMS because of this Agreement or the performance or
nonperformance of services hereunder. The Client and TRANSYSTEMS agree to
require a similar provision in all contracts with contractors, subcontractors,
subconsultants, vendors and other entities involved in this Project to carry out
the intent of this provision.

     TRANSYSTEMS shall not be required to execute any documents subsequent to
the signing of this Agreement that in any way might, in the sole judgment of
TRANSYSTEMS, increase the Consultant's contractual or legal obligations or
risks, or adversely affect the availability or cost of its professional or
general liability insurance.

     SECTION 8.4    HAZARDOUS MATERIALS. Unless otherwise provided in this
Agreement, TRANSYSTEMS shall have no responsibility for the discovery, presence,
handling, removal or disposal of or exposure of persons to hazardous materials
in any form at the Project site. However, TRANSYSTEMS shall report to CLIENT the
presence and location of any hazardous material which it notices or which an
engineer of similar skill and experience should have noticed.

     SECTION 8.5    ATTORNEYS FEES. In the event that either party hereto
employs an attorney to enforce any provision of this Agreement or to collect
damages for default or breach of this Agreement, or pursue claims in litigation
or arbitration, the prevailing party in any such action shall be entitled to
recover from the other such attorneys' fees and costs of collection as the
prevailing party may expend or incur with respect thereto. In the event that a
settlement is reached between the parties before a final decision in any such
litigation or arbitration, then neither party shall be entitled to recover its
attorneys fees or costs from the other and neither party shall be responsible
for the other party's attorney's fees or costs, unless otherwise agreed by the
parties.

     SECTION 8.6    DISPUTES. In the event a dispute arises between TRANSYSTEMS
and CLIENT regarding the application or interpretation of any provision of this
Agreement, or quality of Services by TRANSYSTEMS, the aggrieved party shall
promptly notify the other party to this Agreement of the dispute, but in no
event more than 20 days after such dispute arises. If the parties fail to
resolve the dispute within 20 days after receipt of such notice, each party
shall, within five days thereafter, proceed to non-binding mediation, with each
party to bear its own costs and attorneys' fees (except as otherwise provided in
Section 8,5 above) and the parties shall share equally in the cost of the
mediator. In the event that the mediation is unsuccessful, the aggrieved party
may elect to litigate its dispute with the other party. All disputes shall be
governed by the laws of the State of Missouri and the jurisdiction and venue for
litigation between the parties shall be solely and exclusively in Jackson
County, Missouri, or the United States District Court for the Western District
of Missouri.

     It is intended by the parties to this Agreement that TRANSYSTEMS' services
in connection with the Project shall not subject TRANSYSTEMS' individual
employees, officers or directors to any personal legal exposure for the risks
associated with this Project. Therefore, and notwithstanding anything to the
contrary contained herein, the Client agrees that as the Client's sole and
exclusive remedy, any claim, demand or suit shall be directed and/or asserted
only against TRANSYSTEMS, an interstate corporation, and not against any of
TRANSYSTEMS' individual employees, officers or directors.

hereto, except that it may be assigned without such consent to the successor of
either party, or to a person, firm or corporation acquiring all or substantially
all of the business assets of such party or to a wholly owned subsidiary of
either party, but such assignment shall not relieve the assigning party of any
of its obligations under this Agreement. No assignment of this Agreement shall
be valid until this Agreement shall have been assumed by the assignee. This
Agreement shall be binding upon and shall inure to the benefit of the
TRANSYSTEMS' and CLIENT's respective successors and assigns. Nothing in this
Section 8.9 shall prevent or be deemed to prevent TRANSYSTEMS from employing,
contracting with or engaging independent professional associates, CONSULTANTS

RE:  Fairmont Nebraska Ethanol Facility Engineering - Concept

Mr. Stephenson,

     On February 25, 2005, TranSystems was contacted by yourself, to look at a
potential location for an Ethanol facility in Fairmont, Nebraska. It is our
understanding, per phone conversation, that it is your intent to procure the old
short line railroad (Filmore and Western) that would lead into your primary site
for an ethanol facility. Additionally, it is your intent to use the existing
Filmore and Western right-of-way to add the necessary trackage to service your
planned facility. It is also our understanding that this line is currently
serviced by the BNSF.

     Since this phone call, we have prepared an aerial of the location and are
prepared to perform additional services necessary to start to develop some
concepts to service your planned facility.

     At this time, we would like to have enter into contract with Advanced Bio
Energy for the initial concept phase of work associated with this Fairmont
Nebraska Ethanol facility. Upon acknowledgement of this contract and scope of
services, we are prepared to provide the following:

          -    Perform Site visit of location
          -    Perform cursory investigation into BNSF requirements and Filmore
               and Western
          -    Exhibit with Filmore and Western right-of-way and track to
               support facility
          -    Exhibit with other track options (as necessary)
          -    Cost estimates for design and construction of track.
          -    Identification of additional scope items necessary to pursue the
               procurement of the Filmore and Western line.

The exhibits will provide a conceptual view of a track design over an aerial of
the area. The concepts drawings will be laid out to allow for a capacity that
will match your requirements and the requirements set forth by the BNSF.

     To execute this work, our estimated fee based on the standard rate sheet
attached to this service agreement is $7,000.00. This fee will be based on
actual time and materials spent to perform the scope of work outlined above. I
am confident, we can provide the services required to make this a successful
project. We have standing relationships with all the Class I railroads and have
a ready and capable staff to meet your needs. We appreciate the opportunity to
work on this project for you and look forward to taking this project to the next
phase.

Respectfully Submitted,

Timothy P. Rock
