         "Confidential Information" shall mean any and all information disclosed
by Discloser to Recipient relating to its business or technology that Discloser
designates as being confidential or which, under the circumstances surrounding
disclosure, should be treated as confidential, regardless of whether Discloser

                           Recipient at least as broad in scope as Recipient's

         (ii) Recipient may disseminate necessary portions of the Confidential
Information to consultants, engineers or associates of Recipient for the sole

         A breach of such agreement shall be considered a material breach
hereunder.

         2.2 RESTRICTIONS.

         Except as expressly provided in Section 2.1, Recipient shall not:

         (i)      Publish, disseminate or otherwise disclose or make available

                  Information or products, services, or processes embodying or
                  derived from same. Recipient agrees to use the same degree of
                  care that it uses to protect its confidential information of
                  similar importance, to prevent any unauthorized disclosure of
                  Confidential Information, but in no event less than a
                  reasonable degree of care.
         (iii)    Modify or disseminate the Confidential Information or any part
                  thereof without the express written consent of the Discloser.

         2.3 NO REVERSE ENGINEERING.

        (iv)   though originally, Confidential Information, subsequently is

               development. Recipient shall be entitled to disclose Confidential
               Information in response to a Court Order or as otherwise required
               by law; provided, however; that Recipient notifies Discloser
               prior to such disclosure, and in no case more than ten (10) days

does not give Recipient a license, implied or express, or other rights to the
Confidential Information.

         5.2 OWNERSHIP OF DERIVATIVE WORKS.

         Except as provided in the License Agreement and the Construction
Contract, any and all Derivatives of Confidential Information shall be the

        (ii)   for patentable or patented material any improvement thereon; and
        (iii)  for other material whether or not protected by trade secret, any

         6.1 TERMINATION PRIOR TO CONCLUSION OF AGREEMENT.

         Upon written notice from one party to the other, this Agreement and the

remain in full force and effect with respect to all information, Confidential
Information or otherwise, disclosed prior to the receipt of such written notice.

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, 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 to the

<Page>

         7.3 PRESUMPTIONS.

         In construing the terms of this Agreement, no presumption shall operate
in either party's favor as a result of its counsel's role in drafting the terms
or provisions hereof.

         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
choice of law.

         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
officers, directors, consultants, employees, agents and assigns from and against
any liability, loss or damage arising out of Recipient's violation of 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.

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

provided therein only on such portions of the CONSTRUCTION LOAN proceeds as
actually have been disbursed pursuant to this AGREEMENT.

LOAN shall accrue, for the period through and including the COMPLETION DATE, at

the operations, properties or condition (financial or otherwise) of the BORROWER
since the date of the financial statement referred to above and no additional
borrowings have been made by the BORROWER other than the borrowing contemplated
hereby or approved by the BANK. The above-referenced financial statement or any
certificate or statement furnished to the BANK by or on behalf of the BORROWER
in connection with the transactions contemplated hereby, and the representations
and warranties in this AGREEMENT, do not contain any untrue statements of a
material fact or omit to state a material fact necessary in order to make the

knowledge of the BORROWER, threatened against or affecting the BORROWER or the
properties of the BORROWER before any court or governmental department,

which, if determined adversely to the BORROWER, would have a material adverse
effect on the financial condition, properties, or operations of the BORROWER.

by law for the operation of its business; and 3) the BORROWER has not identified
any "recognized environmental conditions," as that term is defined by the

the PROJECT has all necessary electrical, gas, water, and sewer facilities in
place for the proper construction and operation of its ethanol plant. BORROWER

         any partner or employee of BORROWER, or of any such company.

         6.4.11 Make, or commit to make, capital expenditures (including the
         total amount of any capital leases) in an aggregate amount exceeding
         $250,000.00 in any single fiscal year.

         6.4.12 Make or pay, without the written consent of BANK, which written
         consent will not be unreasonably withheld, in any fiscal year
         distributions to members of the BORROWER in excess of 80% of EXCESS

         distribution not being in compliance with any of the

<Page>

         covenants set forth in this AGREEMENT after payment of such
         distribution. Any such distributions shall be made only after receipt

         CONTRACT, unless such sales or purchases are made or such services are
         rendered in the ordinary course of business and on terms and conditions
         at least as favorable to the BORROWER as the terms and conditions which
         would apply in a similar transaction with a person or party not an
         affiliate of the BORROWER.

SECTION 7 EVENTS OF DEFAULT, RIGHTS AND REMEDIES.

7.1 EVENTS OF DEFAULT. Each of the following shall be an EVENT OF DEFAULT and
give the BANK the right to exercise its remedies under this AGREEMENT:

         7.1.1 The BORROWER shall fail to pay when due any OBLIGATIONS or any
         other installment of principal or interest or fee payable to BANK.

         7.1.2 The BORROWER shall fail to observe or perform any other

         persons, and such failure shall continue beyond any applicable grace
         period, or the BORROWER shall suffer to exist any other default under
         any agreement binding the BORROWER.

         7.1.4 Any financial statement, representation, warranty, or certificate
         made or furnished by or with respect to the BORROWER to the BANK in
         connection with this AGREEMENT, or as an inducement to the BANK to
         enter into this AGREEMENT, or in any separate statement or document to
         be delivered to the BANK hereunder, shall be materially false,
         incorrect, or incomplete when made.

         7.1.5 The BORROWER shall admit its inability to pay its debts as they
         mature or shall make an assignment for the benefit of itself or any of
         its creditors.

         7.1.6 Proceedings in bankruptcy, or for reorganization of the BORROWER,
         or for the readjustment of debt under the Bankruptcy Code, as amended,
         or any part thereof, or under any other laws, whether state or federal,
         for the relief of debtors, now or hereafter existing, shall be
         commenced against or by the BORROWER and, except with respect to any

         7.1.7 A receiver or trustee shall be appointed for the BORROWER or for
         any substantial part of its respective assets, or any proceedings shall
         be instituted for the dissolution or the full or partial liquidation of
         the BORROWER, and except with respect to any such appointments
         requested or instituted by the BORROWER, such receiver or trustee shall
         not be discharged within thirty (30) days of his appointment, and
         except with respect to any such proceedings instituted by the BORROWER,
         such proceedings shall not be discharged within thirty (30) days of
         their commencement, or the BORROWER shall discontinue business or
         materially change the nature of its business, or the property securing
         the OBLIGATIONS becomes, in the reasonable judgment of the BANK,
         insufficient in value to satisfy the OBLIGATIONS, or the BANK otherwise
         reasonably finds itself insecure as to the prompt and punctual payment
         and discharge of the OBLIGATIONS.

         7.1.8 The BORROWER shall suffer final judgments for payment of money
         aggregating in excess of $100,000.00 which are not covered, without
         reservation, by insurance or shall not discharge the same within a
         period of thirty (30) days unless, pending further proceedings,
         execution has not been commenced or, if commenced, has been effectively
         stayed.

         7.1.9 A judgment creditor of the BORROWER shall obtain possession of
         any of the COLLATERAL by any means, including (without implied

         7.1.10 The construction of the PROJECT is abandoned or shall be
         unreasonably delayed or be discontinued for a period of fifteen (15)
         consecutive calendar days, in each instance for reasons other than acts
         of God, fire, storm, strikes, blackouts, labor difficulties, riots,
         inability to obtain materials, equipment or labor, governmental
         restrictions or any similar cause over which the BORROWER is unable to
         exercise control.

         7.1.11 The BORROWER at any time prior to the completion of the PROJECT,
         shall delay construction or suffer construction to be delayed for any
         period of time, for any reason whatsoever, so that the completion of
         the PROJECT cannot be accomplished, in the reasonable judgment of the
         BANK, by the COMPLETION DATE.

         7.1.12 The PROJECT is materially damaged or destroyed by fire or other
         casualty and the loss, in the reasonable judgment of the BANK, is not
         adequately covered by insurance actually collected or in the process of
         collection.

         7.1.13 Broin and Associates, Inc. shall cease to be the GENERAL
         CONTRACTOR or, following COMPLETION DATE, shall cease to be the general

         GENERAL CONTRACTOR, or the GENERAL MANAGER, whichever is applicable,
         within thirty (30) days following the termination of the DESIGN/BUILD
         CONTRACT or the MANAGEMENT CONTRACT, whichever is applicable, to the
         satisfaction of BANK, which BANK approval shall not be unreasonably
         withheld.

<Page>

         7.1.14 Broin Enterprises, Inc. or its permitted assignee shall cease to
         be the marketing agent of BORROWER as to sale of its products, and
         BORROWER has not within thirty (30) days following termination of the
         MARKETING CONTRACT hired a replacement marketing agent to the BANK's
         satisfaction, which BANK approval will not be unreasonably withheld.

7.2 RIGHTS AND REMEDIES. Upon the occurrence of an EVENT OF DEFAULT and at any
time thereafter, the BANK may refrain from making any further disbursements
hereunder (but the BANK may make disbursements after the occurrence of such an
EVENT OF DEFAULT without thereby waiving its rights and remedies hereunder), and
upon the occurrence of an EVENT OF DEFAULT or at any time thereafter, the BANK
may exercise any or all of the following rights and remedies:

         7.2.1 The BANK may declare the CONSTRUCTION LOAN to be terminated,
         whereupon the same shall forthwith terminate.

         7.2.2 The BANK may declare the entire unpaid principal amount of the
         CONSTRUCTION NOTE then outstanding, all interest accrued and unpaid
         thereon, and all other amounts payable under this AGREEMENT to be
         forthwith due and payable, whereupon the CONSTRUCTION NOTE, all such
         accrued interest and all such amounts shall become and be forthwith due
         and payable, without presentment, demand, protest or further notice of
         any kind, all of which are hereby expressly waived by the BORROWER.

         7.2.3 The BANK may exercise and enforce its rights and remedies under
         any or all of the LOAN DOCUMENTS.

         7.2.4 The BANK may enter upon the PROPERTY and take possession thereof,
         together with the PROJECT then in the course of construction, and
         proceed either in its own name or in the name of the BORROWER, as the
         attorney-in-fact of the BORROWER (which authority is coupled with an
         interest and is irrevocable by the BORROWER) to complete or cause to be
         completed the PROJECT, at the cost and expense of the BORROWER. If the
         BANK elects to complete or cause to be completed the PROJECT, it may do
         so according to the PLANS or according to such changes, alterations or
         modifications in and to the PLANS as the BANK may deem reasonable and
         appropriate; and the BANK may enforce or cancel all contracts let by
         the BORROWER relating to construction of the project, and/or let other
         contracts which in the BANK's sole judgment may seem advisable; and the
         BORROWER shall forthwith turn over and duly assign to the BANK, as the
         BANK may from time to time require, contracts not already assigned to
         the BANK relating to construction of the PROJECT, blueprints, shop
         drawings, bonds, building permits, bills and statements of accounts
         pertaining to the PROJECT, whether paid or not, and any other
         instruments or records in the possession of the BORROWER pertaining to
         the PROJECT. The BORROWER shall be liable under this AGREEMENT to pay
         to the BANK, on demand, any amount or amounts expended by the BANK in
         so completing the PROJECT, together with any costs, charges, or
         expenses incident thereto or resulting therefrom, all of which shall be
         secured by the LOAN DOCUMENTS. In the

                                       22
<Page>

         event that a proceeding is instituted against the BORROWER for recovery
         and reimbursement of any moneys expended by the BANK in connection with
         the completion of the PROJECT, a statement of such expenditures,
         verified by the affidavit of an officer of the BANK, shall be prima
         facie evidence of the amounts so expended and of the propriety of the
         necessity for such expenditures; and the burden of proving to the
         contrary shall be upon the BORROWER. The BANK shall have the right to
         apply any funds which it agrees to disburse hereunder to bring about
         the completion of the PROJECT and to pay the costs thereof; and if such
         money so agreed to be disbursed is insufficient, in the sole judgment
         of the BANK, to complete the PROJECT, the BORROWER agrees to promptly
         deliver and pay to the BANK such sum or sums of money as the BANK may
         from time to time demand for the purpose of completing the PROJECT or
         of paying any liability, charge or expense which may have been incurred
         or assumed by the BANK under or in performance of this AGREEMENT, or
         for the purpose of completing the PROJECT. It is expressly understood
         and agreed that in no event shall the BANK be obligated, or liable in
         any way to complete the PROJECT or to pay for the costs of construction
         thereof beyond the amount of the CONSTRUCTION LOAN.

         7.2.5 The BANK may exercise any other rights and remedies available to
         it by law or agreement.

SECTION 8 MISCELLANEOUS.

8.1 INSPECTIONS. The BORROWER and the GENERAL CONTRACTOR shall be responsible
for making inspections of the PROJECT during the course of construction and
shall determine to their own satisfaction that the work done or materials
supplied by the GENERAL CONTRACTOR or any SUBCONTRACTOR to whom payment is to be
made out of each disbursement has been properly done or supplied in accordance
with the DESIGN/BUILD CONTRACT. If any work done or materials supplied by the
GENERAL CONTRACTOR or any SUBCONTRACTOR are not satisfactory to the BORROWER
and/or its GENERAL CONTRACTOR and the same is not remedied within fifteen days
of the discovery thereof, the BORROWER will immediately notify the BANK in
writing of such fact. It is expressly understood and agreed that the BANK and
any party designated by the BANK may conduct such inspections of the PROJECT as
BANK may deem necessary for the protection of the BANK's interest, and that any
inspections which may be made of the PROJECT by the BANK will be made, solely
for the benefit and protection of the BANK, and that the BORROWER will not rely
thereon.

8.2 INDEMNIFICATION BY THE BORROWER. The BORROWER shall bear all loss, expense
(including attorneys' fees) and damage in connection with, and agrees to
indemnify and hold harmless the BANK, its agents, servants and employees from,
all claims, demands and judgments made or recovered against the BANK, its
agents, servants and employees, because of bodily injuries, including death at
any time resulting therefrom, and/or because of damages to property (including
loss of use) from any cause whatsoever, arising out of, incidental to, or in
connection with the construction of the PROJECT, whether or not due to any act
of omission or commission, including negligence of the BORROWER or the GENERAL
CONTRACTOR or of his or their employees, servants or agents, and whether or not
due to any act of omission or

                                       23
<Page>

commission of the BANK, its employees, servants or agents. The BORROWER's
liability hereunder shall not be limited to the extent of insurance carried by
or provided by the BORROWER or subject to any exclusions from coverage in any
insurance policy. The obligations of the BORROWER under this Section shall
survive the payment of the CONSTRUCTION NOTE.

8.3 NO WAIVER; CUMULATIVE REMEDIES. No failure or delay on the part of the BANK
in exercising any right, power or remedy under the LOAN DOCUMENTS shall operate
as a waiver thereof; nor shall any single or partial exercise of any such right,
power or remedy preclude any other or further exercise thereof or the exercise
of any other right, power or remedy under the LOAN DOCUMENTS. The remedies
provided in the LOAN DOCUMENTS are cumulative and not exclusive of any remedies
provided by law.

8.4 AMENDMENTS, ETC. No amendment, modification, termination or waiver of any
provision of any of the LOAN DOCUMENTS or consent to any departure by the
BORROWER therefrom shall be effective unless the same shall be in writing and
signed by the BANK, and then such waiver or consent shall be effective only in
the specific instance and for the specific purpose for which given. No notice to
or demand on the BORROWER in any case shall entitle the BORROWER to any other or
further notice or demand in similar or other circumstances.

Maturity Date:  September 1, 2011

FOR VALUE RECEIVED, DAKOTA ETHANOL, L.L.C., a South Dakota limited liability
company ("BORROWER") promises to pay to the order of First National Bank of
Omaha ("BANK"), at its principal office or such other address as BANK or holder
may designate from time to time, the principal sum of Twenty Six Million Six
Hundred Thousand and No/100 Dollars ($26,600,000.00), or the amount shown on the
BANK's records to be outstanding, plus interest (calculated on the basis of
actual days elapsed in a 360-day year) accruing each day on the unpaid principal
balance at the annual interest rates defined below. Absent manifest error, the
BANK's records shall be conclusive evidence of the principal and accrued
interest owing hereunder.

This promissory note is executed pursuant to a Construction Loan Agreement
("CONSTRUCTION LOAN AGREEMENT") between BORROWER and BANK dated as of
____________, __ 2000. All capitalized terms not otherwise defined in this note
shall have the meanings provided in the CONSTRUCTION LOAN AGREEMENT.

INTEREST ACCRUAL. Interest on the principal amount outstanding shall accrue, for
the period through and including the COMPLETION DATE, at a rate (the "RATE")
equal to the BASE RATE in effect from time to time until maturity, and three per
cent (3%) above the BASE RATE in effect from time to time after maturity,
whether by acceleration or otherwise. For purposes hereof, BASE RATE shall mean
the rate announced by BANK from time to time as its "National Base Rate".

Each time the BASE RATE shall change, the RATE shall change contemporaneously
with such change in the BASE RATE. Interest shall be calculated on the basis of
a 360-day year, counting the actual number of days elapsed.

Following the COMPLETION DATE, interest on the CONSTRUCTION LOAN shall accrue at
a rate of nine (9%) percent per annum prior to maturity, and twelve (12%)
percent per annum after maturity, whether by acceleration or otherwise.

remaining principal balance, plus any accrued but unpaid interest, shall be
fully due and payable on September 1, 2011.

PREPAYMENT. The BORROWER may prepay this CONSTRUCTION NOTE in full or in part at

be paid to BANK sufficient to make BANK whole for any expenses related to

substitutions, contains additional terms and conditions, including default and
acceleration provisions, which are incorporated into this CONSTRUCTION NOTE by
reference. The BORROWER agrees to pay all costs of collection, including
reasonable attorneys fees and legal expenses incurred by the BANK if this
CONSTRUCTION NOTE is not paid as provided above. This CONSTRUCTION NOTE shall be
governed by the substantive laws of the State of Nebraska.

WAIVER OF PRESENTMENT AND NOTICE OF DISHONOR BORROWER and any other person who
signs, guarantees or endorses this CONSTRUCTION NOTE, to the extent allowed by
law, hereby waives presentment, demand for payment, notice of dishonor, protest,
and any notice relating to the acceleration of the maturity of this CONSTRUCTION
NOTE.

         Attn:  Michael Doyle

         I am a manager of DAKOTA ETHANOL, L.L.C., (the "BORROWER") and under
the terms of a CONSTRUCTION LOAN AGREEMENT (the "AGREEMENT") between the BANK
and the BORROWER dated _______________________, 2000, certify that:

1. The attached financial statements of the BORROWER from through (the
"Statement Date") are true and correct and have been accurately prepared in
accordance with generally accepted accounting principles applied consistently
with the BORROWER's most recent annual financial statement; and

2. I have read and am familiar with the AGREEMENT and have no knowledge of an
existing EVENT OF DEFAULT under the AGREEMENT or of any event which would, after
the lapse of time or the giving of notice, or both, constitute an EVENT OF
DEFAULT under the AGREEMENT.

         The calculations regarding each financial covenant, as of the Statement
Date, and regardless of whether the BORROWER must be in compliance with each
covenant as of the Statement Date, are as follows:
