applied against the Retainer. Oregon Trail Ethanol Coalition will be obligated

its development stage and will have limited resources to pay GreenWay for the
Services until such time as Oregon Trail Ethanol Coalition obtains financing

Ethanol Coalition obtains through third-party sources will be attributable, in
part, to GreenWay's efforts in assisting Oregon Trail Ethanol Coalition to
successfully construct and operate the ethanol processing facility, Oregon Trail
Ethanol Coalition shall pay GreenWay a fee for the Services in accordance with
Schedule 1 set forth below.

                two arbitrators shall fail within seven (7) business days of
                their appointment to select a third arbitrator, then upon
                written request of either party, the third arbitrator shall be
                appointed by the American Arbitration Association. If a party
                shall fail to appoint an arbitrator as required the arbitrator
                appointed by the other party shall be the sole arbitrator. The
                arbitration shall be conducted in Omaha, Nebraska.

         (c)    Within fifteen (15) business days of the appointment of the
                arbitrator or panel, as the case may be, each party shall state
                in writing its position concerning the dispute, supported by the
                reasons therefore, and deliver its position to the arbitrator(s)
                and the other party. If either party fails to submit its
                position in a

                timely manner, the position submitted by the other party shall
                be deemed correct, and the arbitration shall be deemed
                concluded. The parties shall then have ten (10) calendar days to
                respond to the position of the other party and deliver that
                response to the arbitrator(s). The arbitrator(s) shall, within
                thirty (30) calendar days thereafter, meet to consider the
                documents presented in order to make a determination by majority
                on the issues in dispute. Within fifteen (15) business days of
                the end of their meeting the arbitrator(s) shall present their
                award. The arbitrator(s) may award a party the right to
                terminate this Agreement if termination is a remedy specified
                herein for the claim which is the subject of the arbitration.

         (d)    Each party in such arbitration shall bear one-half each of the
                expenses of the arbitrator(s), including their fees and costs,
                but each party shall bear their own expenses, including
                attorney's fees.

SECTION 13 - LIMITATION OF LIABILITY; INDEMNIFICATION. As more fully described
in Exhibit B hereto, Oregon Trail Ethanol Coalition will indemnify and hold
GreenWay harmless from and against all claims, liabilities, losses, damages and
expenses incurred, including fees and disbursements of counsel, related to or

                            NON-DISCLOSURE AGREEMENT
                           PROPRIETARY INFORMATION OF
           GREENWAY CONSULTING, LLC AND OREGON TRAIL ETHANOL COALITION

         THIS NON-DISCLOSURE AGREEMENT ("Agreement") is made as of __________,
2002 between Oregon Trail Ethanol Coalition, L.L.C., a Nebraska limited
liability company ("Disclosing Party"), and _______________________, a
_________________________ ("Receiving Party").

PREAMBLE

                  The Disclosing Party and the Receiving Party are currently
involved in discussions concerning the development of an ethanol processing
facility by Oregon Trail Ethanol Coalition (the "Transaction"). As a result of
such discussions, the Receiving Party may have access to certain confidential
information of the Disclosing Party and GreenWay Consulting, LLC ("GreenWay").
The Disclosing Party has entered into a nondisclosure agreement with GreenWay
prohibiting disclosure of GreenWay confidential information, subject to the
Receiving Party executing this Non-Disclosure Agreement. The Parties desire to
enter into this Agreement in order to allow disclosure to the Receiving Party
and prohibit disclosure of such information to any other party. Therefore, in
consideration of the Receiving Party being given access to certain confidential
information of the Disclosing Party and in exchange for the mutual covenant and
promises contained herein, with the intent to be legally bound, the Parties
agree as follows:

AGREEMENT

1.       Confidential Information.

         (a)      As used in this Agreement, the "Confidential Information" of
         the Disclosing Party shall mean all information concerning or related
         to the business, operations, financial condition or prospects of the
         Disclosing Party or any of their respective Affiliates, regardless of
         the form in which such information appears and whether or not such
         information has been reduced to a tangible form, and shall specifically
         include (1) all information regarding the officers, directors,
         employees, equity holders, customers, suppliers, distributors,
         insurers, reinsurers, brokers, independent contractors, sales
         representatives and licensees of the Disclosing Party and their
         respective Affiliates, in each case whether present or prospective, (2)
         all inventions, discoveries, trade secrets, processes, techniques,
         methods, formulae, ideas and know-how of the Disclosing Party and their
         respective Affiliates, (3) all financial statements, audit reports,
         budgets and business plans or forecasts of the Disclosing Party and
         their respective Affiliates and (4) all information concerning or
         related to the Transaction; provided, that the Confidential Information
         of the Disclosing Party shall not include (x) information which is or
         becomes generally known to the public through no act or omission of the
         Receiving Party and (y) information which has been or hereafter is
         lawfully obtained by the Receiving Party from a source other than the
         Disclosing Party (or any of their respective Affiliates or their

                                       11

<PAGE>

                            GREENWAY CONSULTING, LLC
                                  CONFIDENTIAL

         respective officers, directors, employees, equity holders or agents) so
         long as, in the case of information obtained from a third party, such
         third party was or is not, directly or indirectly, subject to an
         obligation of confidentiality owed to the Disclosing Party or any of
         their Affiliates at the time such Confidential Information was or is
         disclosed to the Receiving Party. As used in this Paragraph, an
         "Affiliate" of a Disclosing Party shall mean an entity which controls,
         is controlled by or is under common control of a Disclosing Party, and
         the term "control" shall mean, with respect to any entity, the
         possession, direct or indirect, of the power to direct or cause the
         direction of the management and policies of such entity, whether
         through ownership of voting securities, by contract or otherwise.

2.       Nondisclosure of Confidential Information. Except as otherwise
         permitted by Section 3, the Receiving Party agrees that it will not,
         without the prior written consent of the Disclosing Party, disclose or
         use for its own benefit, or that of any third party, any Confidential
         Information.

3.       Permitted Disclosures. Notwithstanding Section 2, Receiving Party
         shall be permitted to:

         (a)      disclose Confidential Information to its officers, employees
         and counsel, but only to the extent reasonably necessary in order for
         such party to prepare, conduct and execute and deliver definitive
         documents for the Transaction; provided that Receiving Party shall take
         all such action as shall be necessary or desirable in order to ensure
         that each of such persons maintains the confidentiality of any
         Confidential Information that is so disclosed; and

         (b)      disclose Confidential Information to the extent, but only to
         the extent, required by law; provided, that prior to making any
         disclosure pursuant to this subsection, the Receiving Party shall
         notify the Disclosing Party of the same, and the Disclosing Party shall
         have the right to participate with the Receiving Party in determining
         the amount and type of Confidential Information of the Disclosing
         Party, if any, which must be disclosed in order to comply with
         applicable law, including, without limitation, state and federal
         securities laws and regulations.

4.       Return of Confidential Information. If activity in respect of the
         Transaction shall cease without the Transaction being consummated,
         then, promptly after the written request of the Disclosing Party, the
         Receiving Party shall return to the Disclosing Party all Confidential
         Information which is in tangible form and which is then in its
         possession (or in the possession of any of its officers, directors or
         employees).

5.       Term. This Agreement shall continue indefinitely.

6.       Equitable Relief. The Receiving Party acknowledges and agrees that the
         Disclosing Party and GreenWay would be irreparably damaged in the event
         that any of the provisions of this Agreement are not performed by the
         Receiving Party in accordance with their specific terms or are
         otherwise breached. Accordingly, it is agreed that the Disclosing Party
         or GreenWay shall be entitled to an injunction or injunctions to
         prevent breaches of this Agreement by the Receiving Party and shall
         have the right to specifically enforce this Agreement and the terms and
         provisions hereof against the Receiving Party in addition to

                                       12

                                  CONFIDENTIAL

         any other remedy to which the Disclosing Party or GreenWay may be
         entitled in law or equity.

7.       Governing Law. This Agreement shall be a contract under the State of
         Minnesota and for all purposes shall be governed by and construed and
         enforced in accordance with the laws of Minnesota, excluding any choice
         of law provisions.

8.       Successors and Assigns. This Agreement shall be binding upon and inure
         to the benefit of each of the Parties and their respective successors
         and permitted assigns.

9.       No Assignment or Delegation. Any assignment, delegation or attempted
         assignment or delegation of the rights or responsibilities established
         under this Agreement shall be null and void without the prior written
         duly executed consent by the party charged.

10.      Severability of Provisions. If any provision of this Agreement shall be
         held invalid in a court of law, the remaining provisions shall be
         construed as if the invalid provision were not included in this
         Agreement.

11.      Amendment of Agreement. This Agreement may only be amended or modified
         through a written duly executed instrument by the Parties hereto. Any
         attempted oral amendment or modification is ineffective and therefore
         null and void.

12.      No Implied Waiver of Provisions. Either Parties' failure to insist in
         any one or more instances upon strict performance by the other party of
         any of the terms of this Agreement shall not be construed as a waiver
         of any continuing or subsequent failure to perform or a delay in
         performance of any term hereof.

13.      Notices. Any notice required by this Agreement or given in connection
         with this Agreement, shall be in writing, hand delivered or sent via

                                    EXHIBIT B

In consideration of the agreement of GreenWay Consulting to act on behalf of
Oregon Trail Ethanol Coalition pursuant to the attached Agreement, Oregon Trail
Ethanol Coalition agrees to indemnify and hold harmless GreenWay Consulting, its
affiliates (within the meaning of the Securities Act of 1933), and each of their
respective partners, directors, officers, agents, consultants, employees and
controlling persons (within the meaning of the Securities Act of 1933) (GreenWay
Consulting and each such other person or entity are hereinafter referred to as
an "Indemnified Person"), from and against any losses, damages, expenses and
liabilities (collectively "Liabilities") or actions, investigations, inquiries,
arbitrations, claims or other proceedings in respect thereof, including
enforcement of this agreement (collectively "Actions") (Liabilities and Actions
are herein collectively referred to as "Losses"), as they may be incurred
(including all reasonable legal fees and other expenses incurred in connection
with investigating, preparing, defending, paying, settling or compromising any
Losses, whether or not in connection with any pending or threatened Action, and
notwithstanding the absence of a final determination as set forth below as to
Oregon Trail Ethanol Coalition's obligation to reimburse an Indemnified Person
for such Losses and the possibility that such payments might later be held to
have been improper) to which any of them may become subject and which are
related to or arise out of any act, omission, transaction or event contemplated
by the attached Agreement. Oregon Trail Ethanol Coalition will not, however, be
responsible under the foregoing provisions with respect to any Losses to the
extent that it shall have been finally determined by arbitration in accordance
with the terms of the attached Agreement that such Losses resulted primarily
from actions taken or omitted to be taken by an Indemnified Person due to its
gross negligence or willful misconduct. To the extent that any prior payment has
been made by Oregon Trail Ethanol Coalition to such Indemnified Person is so
determined to have been improper by reason of such Indemnified Person's gross
negligence or willful misconduct, such Indemnified Person shall promptly pay
such amount to Oregon Trail Ethanol Coalition, together with interest, at the
prime rate announced from time to time by U.S. Bank, N.A.

GreenWay Consulting shall indemnify and hold harmless Oregon Trail Ethanol
Coalition from and against any and all Losses based primarily on or arising
proximately from any acts of gross negligence, willful misconduct, fraud or
misrepresentations by GreenWay Consulting. GreenWay Consulting shall follow the
same procedure for indemnification of Oregon Trail Ethanol Coalition as set
forth in this Exhibit B as if Oregon Trail Ethanol Coalition was the
"Indemnified Person".

If the indemnity referred to in this Exhibit B should be, for any reason
whatsoever, unenforceable, unavailable or otherwise insufficient to hold each
Indemnified Person harmless, Oregon Trail Ethanol Coalition shall pay to or on
behalf of each Indemnified Person contributions for Losses so that each
Indemnified Person ultimately bears only a portion of such Losses as is
appropriate (i) to reflect the relative benefits received by each

<PAGE>

                            GREENWAY CONSULTING, LLC
                                  CONFIDENTIAL

such Indemnified Person, respectively, on the one hand and Oregon Trail Ethanol
Coalition on the other hand in connection with the transaction or (ii) if the
allocation on that basis is not permitted by applicable law, to reflect not only
the relative benefits referred to in clause (i) above but also the relative
fault of each such Indemnified Person, respectively, and Oregon Trail Ethanol
Coalition as well as any other relevant equitable considerations; provided,
however, that in no event shall the aggregate contribution of all Indemnified
Persons to all Losses in connection with any transaction exceed the amount of
the fee actually received by GreenWay Consulting pursuant to the attached
Agreement. The respective relative benefits received by GreenWay Consulting and
Oregon Trail Ethanol Coalition in connection with any transaction shall be
deemed to be in the same proportion as the aggregate fee paid to GreenWay
Consulting in connection with the transaction bears to the total consideration
of the transaction. The relative fault of each Indemnified Person and Oregon
Trail Ethanol Coalition shall be determined by reference to, among other things,
whether the actions or omissions to act were by such Indemnified Person or
Oregon Trail Ethanol Coalition and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such action or
omission to act.

Oregon Trail Ethanol Coalition also agrees that no Indemnified Person shall have
any liability to Oregon Trail Ethanol Coalition or its affiliates, directors,
officers, employees, agents or shareholders, directly or indirectly, related to
or arising out of the attached Agreement, except Losses incurred by Oregon Trail
Ethanol Coalition which it shall have been finally determined by arbitration in
accordance with the terms of the attached Agreement to have resulted primarily
from actions taken or omitted to be taken by such Indemnified Person due to its
gross negligence or willful misconduct. In no event, regardless of the legal
theory advanced, shall any Indemnified Person be liable for any consequential,
indirect, incidental or special damages of any nature. Oregon Trail Ethanol
Coalition agrees that without GreenWay Consulting's prior written consent it
shall not settle any pending or threatened claim, action, suit or proceeding
related to the attached Agreement unless the settlement also includes an express
unconditional release of all Indemnified Persons from all liability and
obligations arising therefrom, or Oregon Trail Ethanol Coalition reaffirms its
obligations to indemnify for or contribute to Losses incurred by any unreleased
Indemnified Person as herein provided.

Promptly after its receipt of notice of the commencement of any action, any
Indemnified Person will, if a claim in respect thereof is to be made against
Oregon Trail Ethanol Coalition hereunder, notify in writing Oregon Trail Ethanol
Coalition of the commencement thereof; but omission so to notify Oregon Trail
Ethanol Coalition will not relieve Oregon Trail Ethanol Coalition from any
liability hereunder which it may have to any Indemnified Person. If Oregon Trail
Ethanol Coalition so elects, Oregon Trail Ethanol Coalition may assume the
defense of such Action in a timely manner, including the employment of counsel
(reasonably satisfactory to GreenWay Consulting) and payment of expenses,
provided Oregon Trail Ethanol Coalition acknowledges in writing its
unconditional obligation pursuant to this agreement to indemnify GreenWay

                                  CONFIDENTIAL

Consulting in respect of such Action and provides to GreenWay Consulting
evidence reasonably satisfactory to GreenWay Consulting that Oregon Trail
Ethanol Coalition will have the financial resources to conduct such defense
actively and diligently and permits GreenWay Consulting and counsel retained by
GreenWay Consulting at its expense to participate in such defense.
Notwithstanding the foregoing, in the event GreenWay Consulting determines in
its sole discretion that it is advisable for the Indemnified Persons to be
represented by separate counsel, then GreenWay Consulting may employ on behalf
of the Indemnified Persons a single separate counsel to represent or defend such
Indemnified Persons in such action, claim, proceeding or investigation and
Oregon Trail Ethanol Coalition will pay the fees and disbursements of such
separate counsel as incurred.

In the event of any fundamental change involving the corporate structure of
Oregon Trail Ethanol Coalition, such as by merger, plan of exchange or sale of
all or substantially all of its assets, any executory obligations of Oregon
Trail Ethanol Coalition in the attached Agreement shall, if not assumed by
operation of law, be assumed by contract by the acquiring entity or arrangements
made to protect the interests of GreenWay Consulting reasonably satisfactory to
GreenWay Consulting.

If multiple claims are brought against GreenWay Consulting in any Action with
respect to at least one of which indemnification is permitted under applicable
law and provided for under this agreement, Oregon Trail Ethanol Coalition agrees
that any judgment, arbitration award or other monetary award shall be
conclusively deemed to be based on claims as to which indemnification is
permitted and provided for.

The obligations of Oregon Trail Ethanol Coalition referred to above shall be in
addition to any rights that any Indemnified Person may otherwise have.
