$31,100,000.00                                             Milbank, South Dakota
                                                                   July 11, 2001

     FOR VALUE RECEIVED, Northern Lights Ethanol, LLC, a South Dakota limited
liability company ("Borrower"), hereby promises to pay to the order of U.S. Bank
National Association, a national banking association ("Lender", which term shall
include any future holder hereof), at or at such other place as Lender may from
time to time designate in writing, in lawful money of the United States of
America, the principal sum of Thirty-One Million One Hundred Thousand and no/100
Dollars ($31,100,000.00) (the "Loan") or so much thereof as may be advanced
hereunder and to pay interest on the outstanding principal balance hereof from
time to time at the rate set forth herein. The Loan shall initially be known as
the "Construction Loan" and in the event the Construction Loan converts to long
term financing, will be known as the "Term Loan" as of the Conversion Date, as
defined in the Loan Agreement. This Note is given pursuant to that Loan
Agreement between Lender and Borrower dated the same date as this Note.

     CONSTRUCTION LOAN. Borrower will pay the Construction Loan in accordance
with the following terms and conditions:

     1. The Construction Loan shall bear interest from the date of each Advance,
     as defined in the Loan Agreement, at an annual rate equal to one percent
     (1%) plus the prime rate announced by Lender (the "Index"). The interest
     rate shall be adjusted each time the index changes. Lender will strive to
     inform Borrower of each change in the Index, but each adjustment in the
     Index is effective whether or not Lender informs Borrower of such change.
     Payments of all interest accrued hereunder shall be made June 1, September
     1, December 1, and March 1 of each year unless such day is not a Business
     Day as defined in the Loan Agreement (in which case the Business Day which
     immediately follows such day shall apply) in which any amount Advanced
     under the Construction Loan is outstanding (the "Quarterly Payment Date").
     Interest only payments shall be due beginning the first Quarterly Payment
     Date following the First Advance Date, as defined in the Loan Agreement,
     and on each Quarterly Payment Date thereafter.

     2. In the event the Construction Loan qualifies for conversion to the Term
     Loan under the terms of the Loan Agreement, the outstanding principal
     balance of the Construction Loan and all accrued interest thereon shall be
     converted to the Term Loan on the Conversion Date, as defined in the Loan
     Agreement, which shall not be later than December 31, 2002.

<Page>

     3. All accrued interest owed on the Construction Loan shall be paid in full
     on the Conversion Date. In the event the Loan has not been accelerated
     under the terms of the Loan Agreement prior to the Conversion Date, and the
     Loan does not qualify for conversion to the Term Loan under the terms of
     the Loan Agreement, the Maturity Date of the Loan shall be the Conversion
     Date.

     TERM LOAN. In the event the Loan qualifies for conversion from the
Construction Loan to the Term Loan under the terms of the Loan Agreement,
Borrower will pay the Term Loan in accordance with the following terms and
conditions. Borrower acknowledges that any fixed interest rate will increase
according to the term of the Term Loan (the period between the Conversion Date
and the Maturity Date). In no event will the Maturity Date be later than the
seventh (7th) anniversary of the Conversion Date.

     1. Borrower shall have two interest rate options for the Term Loan. The
     first option shall be the same variable rate as provided for the
     Construction Loan. If the variable rate option is chosen, the interest rate
     shall continue to be adjusted each time that the Index changes. The second
     option is a fixed interest rate which will be negotiated by the parties
     prior to the Conversion Date. If the parties negotiate and agree to a fixed
     interest rate, such agreement shall be evidenced by Lender and Borrower
     executing an amendment to this Note setting forth the fixed interest rate
     agreed upon by the parties. If such an amendment to this Note is not
     executed prior to the Conversion Date, the variable rate option shall apply
     to the Term Loan from and after the Conversion Date. Borrower further
     acknowledges that Lender may be required to obtain the consent of all
     participants in the Loan and that Lender may be unable to agree to a fixed
     interest rate without the prior consent of all banks participating in the
     Loan.

     2. The Term Loan shall be amortized over a period of one hundred twenty
     (120) months commencing on the Conversion Date..

     3. If the variable interest rate option applies to the Term Loan, Borrower
     shall make equal quarterly installments of principal and interest
     commencing on the first Quarterly Payment Date following the Conversion
     Date, and continuing on the first day of each Quarterly Payment Date
     thereafter. As of January 1, 2004, and each January 1 thereafter, the
     quarterly installment of principal and interest shall be adjusted so as to
     amortize the then remaining outstanding principal balance over the
     remaining life of the Term Loan.

<Page>

     4. If a fixed rate option applies to the Term Loan, Borrower shall make
     equal quarterly installments of principal and interest commencing on the
     first Quarterly Payment Date following the Conversion Date, and continuing
     on the first day of each Quarterly Payment Date thereafter.

     5. The outstanding principal balance and all interest due thereon shall be
     paid in all events on the Maturity Date.

     TERMS APPLICABLE TO CONSTRUCTION LOAN AND TERM LOAN. The remaining terms of
this Note apply to the Construction Loan and the Term Loan, if the Loan converts
to a Term Loan:

     INTEREST COMPUTATION. Interest shall be calculated on a 365/360 simple
basis; that is, by applying the ratio of the annual interest rate over a year of
360 days, multiplied by the outstanding principal balance, multiplied by the
actual number of days the principal balance is outstanding.

     COORDINATION WITH LOAN AGREEMENT. This Note is the Note referred to in the
Loan Agreement, and is subject to the additional terms and conditions set forth
in the Loan Agreement and the Loan Documents referred to therein. This Note is
secured by a Mortgage, Security Agreement, Assignment of Leases and Rents and
Fixture Financing Statement of even date herewith on real property located in
Grant County, South Dakota, therein described, as well as other collateral
described in the Loan Agreement and the other Loan Documents. Capitalized terms
not defined herein shall have the meaning given such terms in the Loan
Agreement.

     LATE PAYMENT; GRACE PERIOD. If a payment due hereunder is not made within
five days after the date when due, Borrower shall pay to Lender a late payment
charge of Five Hundred Dollars ($500.00) to compensate Lender for a portion of
the cost related to handling the overdue payment. After an Event of Default, as
defined in the Loan Agreement, then the entire principal sum evidenced by this
Note, together with all accrued and unpaid interest, shall, at the option of the
holder hereof, bear interest at the rate per annum (the "Default Rate") equal to
3% in excess of the rate of interest per annum which would otherwise be payable
hereunder, and become immediately due and payable without further notice (except
as provided in the Loan Agreement), demand or presentment for payment, and
without any relief whatever from any valuation or appraisement laws. Failure to
exercise any option provided herein shall not constitute a waiver of the right
to exercise the same in the event of any subsequent default. Borrower agrees
that if, and as often as, this Note is given to an attorney for collection or to
defend

<Page>

or enforce any of Lender's rights hereunder, Borrower will pay to the Lender
Lender's reasonable attorneys' fees together with all court costs, service tax
and other expenses paid by Lender, whether or not any action or proceeding is
commenced by the Lender.

     CERTAIN BORROWER WAIVERS. Borrower waives presentment, protest and demand,
notice of protest, demand and of dishonor and nonpayment of this Note and any
lack of diligence or delays in collection or enforcement of this Note. Borrower
agrees that this Note, or any payment hereunder, may be extended from time to
time, and Borrower consents to the release of any party liable for the
obligation evidenced by this Note, the release of any of the security for this
Note, the acceptance of any other security therefor, or any other indulgence or
forbearance whatsoever, all without notice to any party and without affecting
the liability of Borrower.

     PREPAYMENT; VARIABLE RATE. So long as a variable interest rate is
applicable to this Loan, Borrower may prepay this Note in whole or in part at
any time, and if in part from time to time, during the entire term of this Note,
without penalty or premium. No prepayment shall suspend any required payments of
either principal or interest on this Note or reduce the amount of any scheduled
payment.

     PREPAYMENT; FIXED RATE. If a fixed interest rate is applicable to this
Loan, there shall be no prepayments of this Note, provided that Lender may
consider requests for its consent with respect to prepayment of this Note,
without incurring an obligation to do so, and Borrower acknowledges that in the
event that such consent is granted, Borrower shall be required to pay Lender,
upon prepayment of all or part of the principal amount before final maturity, a
Prepayment Fee equal to the maximum of (a) zero, or (b) that amount, calculated
on any prepayment date, which is derived by subtracting: (1) the principal
amount of the Note or portion of the Note to be prepaid from (2) the Net Present
Value of the Note or portion of the Note to be prepaid on such date of
prepayment.

     "NET PRESENT VALUE" shall mean the amount which is derived by summing the
present values of each prospective payment of principal and interest which,
without such full or partial prepayment, could otherwise have been received by
Lender over the shorter of the remaining contractual life of the Note or next
repricing date if Lender had instead initially invested the Note proceeds at the
Initial Money Market Rate. The individual discount rate used to present value
each prospective payment of interest and/or principal shall be the Money Market
Rate at Prepayment for the maturity matching that of each specific payment of
principal and/or interest.

<Page>

"INITIAL MONEY MARKET RATE" shall mean the rate per annum, determined solely by
Lender, on the Conversion Date, or the most recent re-pricing date occurring
thereafter, or as mutually agreed upon by Borrower and Lender, as the rate at
which Lender would be able to borrow funds in Money Markets for the amount of
this Note and with an interest payment frequency and principal repayment
schedule equal to this Note and for a term as may be arranged and agreed upon by
Borrower and Lender. Such a rate shall include FDIC insurance, reserve
requirements and other explicit or implicit costs levied by any regulatory
agency. Borrower acknowledges that the Lender is under no obligation to actually
purchase and/or match funds for the Initial Money Market Rate of this Note.

     "MONEY MARKET RATE AT PREPAYMENT" shall mean that zero-coupon rate,
calculated on the date of prepayment, and determined solely by Lender, as the
rate in which Lender would be able to borrow funds in Money Markets for the
prepayment amount matching the maturity of a specific prospective Note payment
or repricing date. Such a rate shall include FDIC insurance, reserve
requirements and other explicit or implicit costs levied by any regulatory
agency. A separate Money Market Rate at Prepayment will be calculated for each
prospective interest and/or principal payment date.

     "MONEY MARKETS" shall mean one or more wholesale funding mechanisms
available to Lender, including negotiable certificates of deposit, eurodollar
deposits, bank notes, fed funds, interest rate swaps, or others.

     In calculating the amount of such a prepayment fee, Lender is hereby
authorized by Borrower to make such assumptions regarding the source of funding,
redeployment of funds and other related matters, as the Lender may deem
appropriate. If Borrower fails to pay any Prepayment Fee when due, the amount of
such Prepayment Fee shall thereafter bear interest until paid at the Default
Rate specified in this Note (computed on the basis of a 360-day year, actual
days elapsed). Any prepayment of principal shall be accompanied by a payment of
interest accrued to date thereon; and said prepayment shall be applied to the
principal installments in the inverse order of their maturities. Any prepayment
shall be in an amount equal to the lessor of $100,000.00 or the remaining entire
principal balance of the Loan.

     MANDATORY PREPAYMENTS. In the event the Construction Loan converts to the
Term Loan, the Borrower shall make mandatory prepayments of the principal amount
of the Loan as mandated by the Borrower's excess cash flow from time-to-time, as
provided for in Schedule V of the Loan Agreement.

     MODIFICATIONS; TIME OF ESSENCE. No modification or waiver by the Lender of
any of the terms of this Note shall be valid or binding on the Lender unless
such modification or waiver is in writing and signed by the Lender. Without
limited the generality of the preceding sentence, no delay, omission or
forbearance by the Lender in exercising or enforcing any of its rights and
remedies under this Note shall constitute a waiver of such rights or remedies.
The Lender's rights and remedies under this Note are cumulative with and in
addition to all other legal equitable rights and remedies which the Lender may
have in connection with the Loan. The headings to sections of this Note are for
convenient reference only and shall not be used in interpreting this Note. No
indebtedness evidenced by this Note shall be offset by all or part of any claim,
cause of action, or cross-claim of any kind whether liquidated or unliquidated,
which Borrower now has or may hereafter acquire to allege to have acquired
against the Lender.

     THIS NOTE SHALL BE CONSTRUED UNDER AND GOVERNED BY THE LAWS OF THE STATE OF
SOUTH DAKOTA, WITHOUT GIVING EFFECT TO CONFLICT OF LAWS OR PRINCIPLES THEREOF,
BUT GIVING EFFECT TO FEDERAL LAWS OF THE UNITED STATES APPLICABLE TO NATIONAL
BANKS. WHENEVER POSSIBLE, EACH PROVISION OF THIS NOTE AND ANY OTHER STATEMENT,

RELATING HERETO.

SOUTH DAKOTA CIRCUIT COURT SITTING IN GRANT OR MINNEHAHA COUNTY, SOUTH DAKOTA;
AND BORROWER CONSENTS TO THE JURISDICTION AND VENUE OF ANY SUCH COURT AND WAIVES
ANY ARGUMENT THAT VENUE IN SUCH FORUMS IS NOT CONVENIENT. IN THE EVENT BORROWER
COMMENCES ANY ACTION IN ANOTHER JURISDICTION OR VENUE UNDER ANY TORT OR CONTRACT
THEORY ARISING DIRECTLY OR INDIRECTLY FROM THE RELATIONSHIP CREATED BY THIS
NOTE, LENDER AT ITS OPTION SHALL BE ENTITLED TO HAVE THE CASE

<Page>

TRANSFERRED TO ONE OF THE JURISDICTIONS AND VENUES ABOVE-DESCRIBED, OR IF SUCH
TRANSFER CANNOT BE ACCOMPLISHED UNDER APPLICABLE LAW, TO HAVE SUCH CASE
DISMISSED WITHOUT PREJUDICE.

     Borrower and Lender each irrevocably waives any and all right to trial by
jury in any legal proceeding arising out of or relating to this Note or any of
the Loan Documents (as defined in the Loan Agreement) or the transactions
contemplated hereby or thereby.

rights, privileges and appurtenances thereunto belonging, to the use and benefit
of Lender, its successors and assigns, forever.

the Uniform Commercial Code as in effect in the State of South Dakota (the
"UCC"), with respect to all property described herein as to which a security

     BORROWER FURTHER agrees as follows:

                                    ARTICLE I

                                   AGREEMENTS

     Section 1.1 PERFORMANCE OF OBLIGATIONS; INCORPORATION BY REFERENCE.
Borrower shall pay and perform the Obligations. Time is of the essence hereof.
All of the covenants, obligations, agreements, warranties and representations of
Borrower contained in the Loan Agreement and the other Loan Documents and all of
the terms and provisions thereof, are hereby incorporated herein and made a part
hereof by reference as if fully set forth herein.

     Section 1.2 FURTHER ASSURANCES. If Lender requests, Borrower shall sign and
deliver and cause to be recorded as Lender shall direct any further mortgages,
instruments of further assurance, certificates and other documents as Lender
reasonably may consider necessary or desirable in order to perfect, continue and
preserve the Obligations and Lender's rights, title, estate, liens and interests
under the Loan Documents. Borrower further agrees to pay to Lender, upon demand,
all costs and expenses incurred by Lender in connection with the preparation,
execution, recording, filing and refining of any such documents, including
attorneys' fees and title insurance costs.

     Section 1.3 SALE, TRANSFER, ENCUMBRANCE. If Borrower sells, conveys,
transfers or otherwise disposes of, or encumbers, any part of its interest in
the Mortgaged Property,

<Page>

whether voluntarily, involuntarily or by operation of law, without the prior
written consent of Lender, Lender shall have the option to declare the
Obligations immediately due and payable without notice. Included within the
foregoing actions requiring prior written consent of Lender are: (a) sale by
deed or contract for deed; (b) mortgaging or granting a lien on the Mortgaged
Property; and (c) a transfer which changes the persons in control of Borrower or
which transfers more than 25% of the beneficial interest in Borrower, except for
transfers to Affiliates as defined in the Loan Agreement; and (d) Borrower's
entry into a Lease. Borrower shall give notice of any proposed action to Lender
at least thirty (30) days prior to taking such action. Borrower shall pay all
costs and expenses incurred by Lender in evaluating any such action. Lender may
condition such consent upon modification of the Loan Documents or payment of
fees. No such action shall relieve Borrower from liability for the Obligations.
The consent by Lender to any action shall not constitute a waiver of the
necessity of such consent to any subsequent action.

     Section 1.4 INSURANCE. Borrower shall obtain, maintain and keep in full
force and effect (and upon request of Lender shall furnish to Lender copies of)
policies of insurance as described in, and meeting the requirements set forth
in, Exhibit B attached hereto, and upon request of Lender shall furnish to
Lender proof of payment of all premiums for such insurance. At least ten (10)
days prior to the termination of any such coverage, Borrower shall provide
Lender with evidence satisfactory to Lender that such coverage will be renewed
or replaced upon termination with insurance that complies with the provisions of
this Section. Borrower, at its sole cost and expense, from time to time when
Lender shall so request, will provide Lender with evidence, in a form acceptable
to Lender, of the full insurable replacement cost of the Mortgaged Property. All
property (including boiler and machinery) and liability insurance policies
maintained by Borrower pursuant to this Section shall (i) include effective
waivers by the insurer of all claims for insurance premiums against Lender, and
(ii) provide that any losses shall be payable notwithstanding (a) any act of
negligence by Borrower or Lender, (b) any foreclosure or other proceedings or
notice of foreclosure sale relating to the Mortgaged Property, or (c) any
release from liability or waiver of subrogation rights granted by the insured.
All insurance policies maintained by Borrower pursuant to the foregoing
provisions shall respond on a primary basis relative to any other insurance
carried by Lender in the event of loss. Insurance terms not otherwise defined
herein shall be interpreted consistent with insurance industry usage.

     Section 1.5 TAXES, LIENS AND CLAIMS, UTILITIES. Except as otherwise
provided in the Loan Agreement, Borrower, at least give (5) days before any
penalty attaches thereto, shall pay and discharge, or cause to be paid and
discharged, all taxes, assessments and

<Page>

governmental charges and levies (collectively "Impositions") imposed upon or
against the Mortgaged Property or the Rents, or upon or against the Obligations,
or upon or against the interest of Lender in the Mortgaged Property or the
Obligations, except Impositions measured by the income of Lender. Borrower shall
provide evidence of such payment at Lender's request. Except as otherwise
provided in the Loan Agreement, Borrower shall keep the Mortgaged Property free
and clear of all liens, encumbrances, easements, covenants, conditions,
restrictions and reservations (collectively "Liens") except those listed on
Exhibit A attached hereto (the "Permitted Encumbrances"). Borrower shall pay or
cause to be paid when due all charges or fees for utilities and services
supplied to the Mortgaged Property. Notwithstanding anything to the contrary
contained in this Section, Borrower shall not be required to pay or discharge
any Imposition or Lien so long as Borrower shall in good faith, and after giving
notice to Lender, contest the same by appropriate legal proceedings. If Borrower
contests any Imposition or Lien against the Mortgaged Property, Borrower shall
provide such security to Lender as Lender shall reasonably require against loss
or impairment of Borrower's ownership of or Lender's lien on the Mortgaged
Property and shall in any event pay such Imposition or Lien before loss or
impairment occurs.

     Section 1.6 ESCROW PAYMENTS. If requested by Lender, Borrower shall deposit
with Lender monthly on the same date as payments are due under the Note the
amount reasonably estimated by Lender to be necessary to enable Lender to pay,
at least five (5) days before they become due, all Impositions against the
Mortgaged Property and the premiums upon all insurance required hereby to be
maintained with respect to the Mortgaged Property. All funds so deposited shall
secure the Obligations. Such deposits shall be held by Lender, or its nominee,
in a non-interest bearing account and may be commingled with other funds. Such
deposits shall be used to pay such Impositions and insurance premiums when due.
Any excess sums so deposited shall be retained by Lender and shall be applied to
pay said items in the future, unless the Obligations have been paid and
performed in full, in which case all excess sums so paid shall be refunded to
Borrower. Upon the occurrence of an Event of Default, Lender may apply any funds
in said account against the Obligations in such order as Lender may determine.

     Section 1.7 MAINTENANCE AND REPAIR, COMPLIANCE WITH LAWS. Borrower shall
cause the Mortgaged Property to be operated, maintained and repaired in safe and
good repair, working order and condition, reasonable wear and tear excepted;
shall not commit or permit waste thereof; except as provided in any Loan
Document, shall not remove, demolish or substantially alter the design or
structural character of any Improvements without the prior written consent of
Lender; shall complete or cause to be completed forthwith any Improvements which
are now or may hereafter be under construction upon

<Page>

the Land; shall comply or cause compliance with all laws, statutes, ordinances
and codes, and governmental rules, regulations and requirements, applicable to
the Mortgaged Property or the manner of using or operating the same, and with
any covenants, conditions, restrictions and reservations affecting the title to
the Mortgaged Property, and with the terms of all insurance policies relating to
the Mortgaged Property; and shall obtain and maintain in full force and effect
all consents, permits and licenses necessary for the use and operation of the
Mortgaged Property.

     Section 1.8 LEASES UNDER WHICH BORROWER IS LANDLORD.

     (a) Borrower shall not enter into, modify, amend, cancel or terminate any
Leases without Lender's prior written consent, and shall furnish to Lender, upon
execution, a complete and fully executed copy of each of the Leases.

     (b) Borrower shall, at its cost and expense, perform each obligation to be
performed by Borrower under each of the Leases; not borrow against, pledge or
further assign any rents or other payments due thereunder; not permit the
prepayment of any rents or other payments due for more than thirty (30) days in
advance; and not permit any Tenant to assign its Lease or sublet the premises
covered by its Lease, unless required to do so by the terms thereof and then
only if such assignment does not work to relieve the Tenant of any liability for
performance of its obligations thereunder.

     (c) If any Tenant shall default under its Lease, Borrower shall, in the
ordinary course of business, exercise sound business judgment with respect to
such default, but may discount, compromise, forgive or waive claims or discharge
the Tenant from its obligations under the Lease or terminate or accept a
surrender of the Lease.

     (d) If Borrower fails to perform any obligations of Borrower under any
Leases or if Lender becomes aware of or is notified by any Tenant of a failure
on the part of Borrower to so perform, Lender may, but shall not be obligated
to, without waiving or releasing Borrower from any obligation in this Agreement
or any of the other Loan Documents, remedy such failure, and Borrower agrees to
repay upon demand all sums incurred by Lender in remedying any such failure,
together with interest thereon from the date incurred at the Default Rate (as
defined in the Note).

     (e) For purposes of this Section, the defined terms shall have the meanings
provided in this Mortgage, including the following defined terms:

<Page>

     (i) "LEASE": Any lease or other document or agreement, written or oral,
     permitting any Person, other than Borrower, to use or occupy any part of
     the Mortgaged Property.

     (ii) "TENANT": Any Person, other than Borrower, using or occupying any part
     of the Mortgaged Property pursuant to a Lease.

     (f) Nothing in this Section 1.8 constitutes consent by Lender to Borrower
entering into any Lease, and it is acknowledged that Borrower's entry into a
Lease without the Lender's prior written consent is a violation of Section 3.1
of this Agreement.

     Section 1.9 INDEMNITY. Borrower shall indemnify Lender and its directors,
officers, agents and employees (collectively the "Indemnified Parties") against,
and hold the Indemnified Parties harmless from, all losses, damages, suits,
claims, judgments, penalties, fines, liabilities, costs and expenses by reason
of, or on account of, or in connection with the construction, reconstruction or
alteration of the Mortgaged Property, or any accident, injury, death or damage
to any person or property occurring in, on or about the Mortgaged Property or
any street, drive, sidewalk, curb or passageway adjacent thereto. The indemnity
contained in this Section shall include costs of defense of any such claim
asserted against an Indemnified Party, including attorneys' fees. The indemnity
contained in this Section shall survive payment and performance of the
Obligations and satisfaction and release of this Mortgage and any foreclosure
thereof or acquisition of title by deed in lieu of foreclosure.

     (a) Borrower shall not modify, amend, cancel or terminate the Big Stone

written consent.

     (b) Borrower shall, at its cost and expense, timely perform each obligation
to be performed by Borrower under the Big Stone Plant Property Lease and the
Access and Rail Agreement.

     (c) If Borrower fails to timely perform any obligations of Borrower under
the Big Stone Plant Property Lease, the Access and Rail Agreement or if Lender
becomes aware of or is notified by Big Stone-Grant Industrial Development and
Transportation, L.L.C., the Big Stone Plant Co-Owners or any other party or a
failure on the part of Borrower to so perform, Lender may, but shall not be
obligated to, without waiving or releasing Borrower from any obligation in this
Agreement or any of the other Loan

<Page>

Documents, remedy such failure, and Borrower agrees to repay upon demand all
sums incurred by Lender in remedying any such failure, together with interest
thereon from the date incurred at the Default Rate (as defined in the Note).

     Borrower makes the following representations and warranties:

     Section 2.1 OWNERSHIP, LIENS, COMPLIANCE WITH LAWS. Borrower owns the
Mortgaged Property free from all Liens, except the Permitted Encumbrances. All
applicable zoning, environmental, land use, subdivision, building, fire, safety
and health laws, statutes, ordinances, codes, rules, regulations and
requirements affecting the Mortgaged Property permit the current use and
occupancy thereof, and Borrower has obtained all consents, permits and licenses
required for such use. Borrower has examined and is familiar with all applicable
covenants, conditions, restrictions and reservations, and with all applicable
laws, statutes, ordinances, codes and governmental rules, regulations and
requirements affecting the Mortgaged Property, and the Mortgaged Property
complies with all of the foregoing.

     Section 2.2 USE. The Mortgaged Property is not homestead property nor is it
agricultural property or in agricultural use.

     Section 2.3 UTILITIES, SERVICES. The Mortgaged Property is serviced by all
necessary public utilities, and all such utilities are operational and have
sufficient capacity.

     Section 2.4 ACCESS AGREEMENT. The Access and Rail Agreement is in full
force and effect, and has not been amended, modified, terminated or cancelled,
and there is no default by Borrower thereunder, nor any statement of facts or
circumstances which, with the giving of notice or the lapse of time or both,
would constitute a default by Borrower thereunder or entitle the Big Stone Plant
Co-Owners to terminate the Access and Rail Agreement; nor has Borrower received
or given any notice of default or termination.

     Section 2.5 BIG STONE PLANT PROPERTY LEASE. The Lease is in full force and
effect, and has not been amended, modified, terminated or cancelled, and there
is no default by Borrower thereunder, nor any statement of facts or
circumstances which, with the giving of notice or the lapse of time or both,

<Page>

or entitle Big Stone-Grant Industrial Development and Transportation, L.L.C. to
terminate the Big Stone Plant Property Lease, nor has Borrower received or given
any notice of default or termination. Borrower has provided Lender a true and

                                   ARTICLE III

                             CASUALTY; CONDEMNATION

     Section 3.1 CASUALTY, REPAIR PROOF OF LOSS. If any portion of the Mortgaged
Property shall be damaged or destroyed by any cause (a "Casualty"), Borrower
shall:

          (a) give immediate notice to the Lender; and

          (b) promptly commence and diligently pursue to completion (in
          accordance with plans and specifications approved by Lender) the
          restoration, repair and rebuilding of the Mortgaged Property as nearly
          as possible to its value, condition and character immediately prior to
          the Casualty; and

     (c) if the Casualty is covered by insurance, immediately make proof of loss
     and collect all insurance proceeds, all such proceeds to be payable to
     Lender or as Lender shall direct. If an Event of Default shall be in
     existence, or if Borrower shall fail to provide notice to Lender of filing
     proof of loss, or if Borrower shall not be diligently proceeding, in
     Lender's reasonable opinion, to collect such insurance proceeds, then
     Lender may, but is not obligated to, make proof of loss, and is authorized,
     but is not obligated, to settle any claim with respect thereto, and to
     collect the proceeds thereof. Borrower shall not accept any settlement of
     an insurance claim, the result of which shall be a payment which is
     $100,000.00 or more less than the full amount of the claim, without the
     prior written consent of Lender.

     Section 3.2 USE OF INSURANCE PROCEEDS. Lender shall make the net insurance
proceeds received by it (after reimbursement of Lender's out-of pocket costs of
collecting and disbursing the same) available to Borrower to pay the cost of
restoration, repair and rebuilding of the Mortgaged Property, subject to the
following conditions:

     (a)   There shall be no Event of Default in existence at the time of any
     disbursement of the insurance proceeds.

<Page>

     (b) Lender shall have determined, in its reasonable discretion, that the
     cost of restoration, repair and rebuilding is and will be equal to or less
     than the amount of insurance proceeds and other funds deposited by Borrower
     with Lender.

     (c) Lender shall have determined, in its reasonable discretion, that the
     restoration, repair and rebuilding can be completed in accordance with
     plans and specifications approved by Lender (such approval not to be
     unreasonably withheld), in accordance with codes and ordinances and in
     accordance with the terms, and within the time requirements in order to
     prevent termination, of the Big Stone Plant Property Lease, the Access and
     Rail Agreement or any other Lease, and in any event not less than six (6)
     months prior to the Maturity Date.

     (d) All funds shall be disbursed, at Lender's option, in accordance with
     Lender's customary disbursement procedures for construction loans.

     (e) The Casualty shall have occurred more than twelve (12) months prior to
     the Maturity Date.

If any of these conditions shall not be satisfied, then Lender shall have the
right to use the insurance proceeds to prepay the Loan in accordance with the
Note. If any insurance proceeds shall remain after completion of the
restoration, repair and rebuilding of the Mortgaged Property, they shall be
disbursed to Borrower, or at the Lender's discretion, used to prepay the Loan in
accordance with the Note.

     Section 3.3 CONDEMNATION. If any portion of the Mortgaged Property shall be
taken, condemned or acquired pursuant to exercise of the power of eminent domain
or threat thereof (a "Condemnation"), Borrower shall:

     (a) give immediate notice thereof to Lender, and send a copy of each
     document received by Borrower in connection with the Condemnation to Lender
     promptly after receipt; and

     (b) diligently pursue any negotiation and prosecute any proceeding in
     connection with the Condemnation at Borrower's expense. If an Event of
     Default shall be in existence, or if Borrower, in Lender's reasonable
     opinion, shall not be diligently negotiating or prosecuting the claim,
     Lender is authorized, but not required, to negotiate and prosecute the
     claim and appear at any hearing for itself and on behalf of Borrower and to
     compromise or settle all compensation for the

<Page>

     Condemnation. Lender shall not be liable to Borrower for any failure by
     Lender to collect or to exercise diligence in collecting any such
     compensation. Borrower shall not compromise or settle any claim resulting
     from the Condemnation if such settlement shall result in payment of One
     Hundred Thousand and No/100 Dollars ($100,000.00) or more less than
     Lender's reasonable estimate of the damages therefrom. All awards shall be
     paid to Lender.

     Section 3.4 USE OF CONDEMNATION PROCEEDS. Lender shall make the net
proceeds of any Condemnation received by it (after reimbursement of Lender's
out-of-pocket costs of collecting and disbursing the same) available to Borrower
for restoration, repair and rebuilding of the Mortgaged Property, subject to the
following conditions:

     (a) There shall be no Event of Default in existence at the time of any
     disbursement of the condemnation proceeds.

     (b) Lender shall have determined, in its reasonable discretion, that the
     cost of restoration, repair and rebuilding is and will be equal to or less
     than the amount of condemnation proceeds and other funds deposited by
     Borrower with Lender.

     (c) Lender shall have determined, in its reasonable discretion, that the
     restoration, repair and rebuilding can be completed in accordance with
     plans and specifications approved by Lender (such approval not to be
     unreasonably withheld), in accordance with codes and ordinances and in
     accordance with the terms, and within the time requirements in order to
     prevent termination, of the Big Stone Plant Property Lease, the Access and
     Rail Agreement or any other Lease, and in any event not less than six (6)
     months prior to the Maturity Date.

     (d) All funds shall be disbursed, at Lender's option, in accordance with
     Lender's customary disbursement procedures for construction loans.

     (e) The Condemnation shall have occurred more than twelve (12) months prior
     to the Maturity Date.

If any of these conditions shall not be satisfied, then Lender shall have the
right to use the condemnation proceeds to prepay the Loan in accordance with the
Note. If any condemnation proceeds shall remain after completion of the
restoration, repair and rebuilding of the Mortgaged Property, they shall be
disbursed to Borrower, or at Lender's discretion, used to prepay the Loan in
accordance with the Note.

                                   ARTICLE IV

                              DEFAULTS AND REMEDIES

     Section 4.1 EVENTS OF DEFAULT. An Event of Default, as defined in the Loan
Agreement, shall constitute an Event of Default hereunder.

     Section 4.2 REMEDIES. Upon the occurrence of an Event of Default described
in the Loan Agreement, and upon the expiration of the applicable cure period
stated therein, if any, all of the Obligations shall be accelerated and become
immediately due and payable without notice or declaration to Borrower. The
Obligations shall be due and payable without presentment, demand or further
notice of any kind. Lender shall have the right to proceed to protect and
enforce its rights by one or more of the following remedies:

            (a) LENDER SHALL HAVE THE RIGHT TO BRING SUIT either for damages,
     for specific performance of any agreement contained in any Loan Document,
     for the foreclosure of this Mortgage, or for the enforcement of any other
     appropriate legal or equitable remedy.

     (b) LENDER SHALL HAVE THE RIGHT TO SELL THE MORTGAGED PROPERTY AT PUBLIC
     AUCTION AND CONVEY THE SAME TO THE PURCHASER IN FEE SIMPLE, as provided by
     law, Borrower to remain liable for any deficiency. Said sale may be as one
     tract or otherwise, at the sole option of Lender. In the event of any sale
     of the Mortgaged Property pursuant to any judgment or decree of any court
     or at public auction or otherwise in connection with the enforcement of any
     of the terms of this Mortgage, Lender, its successors or assigns, may
     become the purchaser, and for the purpose of making settlement for or
     payment of the purchase price, shall be entitled to deliver over and use
     the Note and any claims for interest accrued and unpaid thereon, together
     with all other sums, with interest, advanced or secured hereby and unpaid
     hereunder, in order that there may be credited as paid on the purchase
     price the total amount of the Obligations then due, including principal and
     interest on the Note and all other sums, with interest, advanced or secured
     hereby and unpaid hereunder or under any of the other Loan Documents.

     (c) LENDER SHALL HAVE THE RIGHT TO OBTAIN THE APPOINTMENT OF A RECEIVER at
     any time after the occurrence of an Event of Default. Lender may apply for
     the appointment of a receiver to the circuit court for the county where the
     Mortgaged Property or any part thereof is located, by an

<Page>

     action separate from any foreclosure of this Mortgage pursuant to SDCL
     Chap. 21-21, or as a part of the foreclosure action under SDCL Chap. 21-47
     or SDCL Chap. 21-48 (it being agreed that the existence of a foreclosure
     pursuant to SDCL Chapter 21-47 or SDCL Chap. 21-48 is not a prerequisite to
     any action for a receiver hereunder). Lender shall be entitled to the
     appointment of a receiver without regard to waste, adequacy of the security
     or solvency of Borrower. The receiver, who shall be an experienced property
     manager, shall collect (until the Obligations are fully paid and satisfied
     and, in the case of a foreclosure sale, during the entire redemption
     period) the Rents, and shall manage the Mortgaged Property, execute Leases
     within or beyond the period of the receivership if approved by the court
     and apply all rents, profits and other income collected by him in the
     following order:

           (i)   to the payment of all reasonable fees of the receiver, if any,
           approved by the court;

           (ii)  to the repayment of tenant security deposits, with interest
           thereon;

           (iii) to the payment when due of delinquent or current real estate
           taxes or special assessments with respect to the Mortgaged Property,
           or the periodic escrow for the payment of the same;

           (iv)  to the payment when due of premiums for insurance of the type
           required by this Mortgage, or the periodic escrow for the payment of
           the same;

           (v)   to the payment of all expenses for normal maintenance of the
           Mortgaged Property; and

           (vi) the balance to Lender (a) if received prior to the commencement
           of a foreclosure, to be applied to the Obligations, in such order as
           Lender may elect and (b) if received after the commencement of a
           foreclosure, to be applied to the amount required to be paid to
           effect a reinstatement prior to foreclosure sale, or, after a
           foreclosure sale to any deficiency and thereafter to the amount
           required to be paid to effect a redemption, with any excess to be
           paid to Borrower. Provided, that if this Mortgage is not reinstated
           nor the Mortgaged Property redeemed as provided by applicable law,
           the entire amount paid to Lender pursuant hereto shall be the
           property of Lender

<Page>

           together with all or any part of the Mortgaged Property acquired
           through foreclosure.

     Lender shall have the right, at any time and without limitation, to advance
     money to the receiver to pay any part or all of the items which the
     receiver should otherwise pay if cash were available from the Mortgaged
     Property and sums so advanced, with interest at the Default Rate set forth
     in the Note, shall be secured hereby, or if advanced during the period of
     redemption shall be part of the sum required to be paid to redeem from the
     sale.

     (d) LENDER SHALL HAVE THE RIGHT TO COLLECT THE RENTS from the Mortgaged
     Property and apply the same in the manner hereinbefore provided with
     respect to a receiver. For that purpose, Lender may enter and take
     possession of the Mortgaged Property and manage and operate the same and
     take any action which, in Lender's judgment, is necessary or proper to
     collect the Rents and to conserve the value of the Mortgaged Property.
     Lender may also take possession of, and for these purposes use, any and all
     of the Personal Property. The expense (including any receiver's fees,
     attorneys' fees, costs and agent's compensation) incurred pursuant to the
     powers herein contained shall be secured by this Mortgage. Lender shall not
     be liable to account to Borrower for any action taken pursuant hereto other
     than to account for any Rents actually received by Lender. Enforcement
     hereof shall not cause Lender to be deemed a mortgagee in possession unless
     Lender elects in writing to be a mortgagee IN possession.

     (e) LENDER SHALL HAVE THE RIGHT TO ENTER AND TAKE POSSESSION of the
     Mortgaged Property and manage and operate the same in conformity with all
     applicable laws and take any action which, in Lender's judgment, is
     necessary or proper to conserve the value of the Mortgaged Property.

     (f) LENDER SHALL HAVE ALL OF THE RIGHTS AND REMEDIES PROVIDED IN THE
     UNIFORM COMMERCIAL CODE including the right to proceed under the Uniform
     Commercial Code provisions governing default as to any Personal Property
     separately from the real estate included within the Mortgaged Property, or
     to proceed as to all of the Mortgaged Property in accordance with its
     rights and remedies in respect of said real estate. If Lender should elect
     to proceed separately as to such Personal Property, Borrower agrees to make
     such Personal Property available to Lender at a place or places acceptable
     to Lender, and if any notification of intended disposition of any of such
     Personal Property is required by law, such notification shall be deemed
     reasonably and

<Page>

     properly given if given at least ten (10) days before such disposition in
     the manner hereinafter provided.

     (g) LENDER SHALL HAVE THE RIGHT TO FILE PROOF OF CLAIM and other documents
     as may be necessary or advisable in order to have its claims allowed in any
     receivership, insolvency, bankruptcy, reorganization, arrangement,
     adjustment, composition or other judicial proceedings affecting Borrower,
     its creditors or its property, for the entire amount due and payable by
     Borrower in respect of the Obligations at the date of the institution of
     such proceedings, and for any additional amounts which may become due and
     payable by Borrower after such date.

Each remedy herein specifically given shall be in addition to every other right
now or hereafter given or existing at law or in equity, and each and every right
may be exercised from time to time and as often and in such order as may be
deemed expedient by Lender and the exercise or the beginning of the exercise of
one right shall not be deemed a waiver of the right to exercise at the same time
or thereafter any other right. Lender shall have all rights and remedies
available under the law in effect now and/or at the time such rights and
remedies are sought to be enforced, whether or not they are available under the
law in effect on the date hereof.

     Section 4.3 EXPENSES OF EXERCISING RIGHTS, POWERS AND REMEDIES. The
reasonable expenses (including any receiver's fees, attorneys' fees, appraisers'
fees, environmental engineers' and/or consultants' fees, costs incurred for
documentary and expert evidence, stenographers' charges, publication costs,
costs (which may be estimated as to items to be expended after entry of the
decree of foreclosure) of procuring all abstracts of title, continuations of
abstracts of title, title searches and examinations, title insurance policies
and commitments and extensions therefor, Torrens duplicate certificates of
title, UCC and chattel lien searches, and similar data and assurances with
respect to title as Lender may deem reasonably necessary either to prosecute any
foreclosure action or to evidence to bidders at any sale which may be had
pursuant to any foreclosure decree the true condition of the title to or the
value of the Mortgaged Property, and agent's compensation) incurred by Lender
after the occurrence of any Event of Default and/or in pursuing the rights,
powers and remedies contained in this Mortgage shall be immediately due and
payable by Borrower, with interest thereon from the date incurred at the Default
Rate set forth in the Note, and shall be added to the indebtedness secured by
this Mortgage.

<Page>

     Section 4.4 RESTORATION OF POSITION. In case Lender shall have proceeded to
enforce any right under this Mortgage by foreclosure, sale, entry or otherwise,
and such proceedings shall have been discontinued or abandoned for any reason or
shall have been determined adversely, then, and in every such case, Borrower and
Lender shall be restored to their former positions and rights hereunder with
respect to the Mortgaged Property subject to the lien hereof.

     Section 4.5 MARSHALING. Borrower, for itself and on behalf of all persons,
parties and entities which may claim under Borrower, hereby waives all
requirements of law relating to the marshalling of assets, if any, which would
be applicable in connection with the enforcement by Lender of its remedies for
an Event of Default hereunder, absent this waiver. Lender shall not be required
to sell or realize upon any portion of the Mortgaged Property before selling or
realizing upon any other portion thereof.

     Section 4.6 WAIVERS. No waiver of any provision hereof shall be implied
from the conduct of the parties. Any such waiver must be in writing and must be
signed by the party against which such waiver is sought to be enforced. The
waiver or release of any breach of the provisions set forth herein to be kept
and performed shall not be a waiver or release of any preceding or subsequent
breach of the same or any other provision. No receipt of partial payment after
acceleration of any of the Obligations shall waive the acceleration. No payment
by Borrower or receipt by Lender of a lesser amount than the full amount secured
hereby shall be deemed to be other than on account of the sums due and payable
hereunder, nor shall any endorsement or statement on any check or any letter
accompanying any check or payment be deemed an accord and satisfaction, and
Lender may accept any check or payment without prejudice to Lender's right to
recover the balance of such sums or to pursue any other remedy provided in this
Mortgage. The consent by Lender to any matter or event requiring such consent
shall not constitute a waiver of the necessity for such consent to any
subsequent matter or event.

     Section 4.7 LENDER'S RIGHT TO CURE DEFAULTS. If Borrower shall fail to
comply with any of the terms of the Loan Documents with respect to the procuring
of insurance, the payment of taxes, assessments and other charges, the keeping
of the Mortgaged Property in repair, or any other term contained herein or in
any of the other Loan Documents, Lender may make advances to perform the same
without releasing Borrower from any of the Obligations. Borrower agrees to repay
upon demand all sums so advanced and all sums expended by Lender in connection
with such performance, including without limitation attorneys' fees, with
interest at the Default Rate set forth in the Note from the dates such advances
are made, and all sums so advanced and/or expenses incurred, with interest,
shall be secured hereby, but no such advance and/or incurring of expense by

<Page>

Lender, shall be deemed to relieve Borrower from any default hereunder or under
any of the other Loan Documents, or to release Borrower from any of the
Obligations.

     Section 4.8 SUITS AND PROCEEDINGS. Lender shall have the power and
authority, upon prior notice to Borrower, to institute and maintain any suits
and proceedings as Lender may deem advisable to (i) prevent any impairment of
the Mortgaged Property by any act which may be unlawful or by any violation of
this Mortgage, (ii) preserve or protect its interest in the Mortgaged Property,
or (iii) restrain the enforcement of or compliance with any legislation or other
governmental enactment, rule or order that may be unconstitutional or otherwise
invalid, if, in the sole opinion of Lender, the enforcement of or compliance
with such enactment, rule or order might impair the security hereunder or be
prejudicial to Lender's interest.

                                    ARTICLE V

                                  MISCELLANEOUS

     Section 5.1 BINDING EFFECT, SURVIVAL; NUMBER; GENDER. This Mortgage shall
be binding on and inure to the benefit of the parties hereto, and their
respective heirs, legal representatives, successors and assigns. All agreements,
representations and warranties contained herein or otherwise heretofore made by
Borrower to Lender shall survive the execution, delivery and foreclosure hereof.
The singular of all terms used herein shall include the plural, the plural shall
include the singular, and the use of any gender herein shall include all other
genders, where the context so requires or permits.

     Section 5.2 SEVERABILITY. The unenforceability or invalidity of any

locations in the ordinary course of business) unless, prior to any such removal,
Borrower has given written notice to the Secured Party of the location or
locations to which the Borrower desires to remove the same, and the Secured
Party has given its written consent to such removal. If any of the locations
where Borrower now or hereafter keeps the Collateral are leased by the Borrower,
the Borrower shall at Secured Party's request, obtain a Landlord's waiver in a
form satisfactory to Secured Party. All of the Borrower's inventory and
equipment shall, if so provided above, constitute Collateral, even if located at
a location not set forth above.

     2. Borrower is incorporated in the State of South Dakota. Borrower's
principal place of business has a post office address of Post Office Box 225,
Milbank, South Dakota 57252. Borrower will notify the Secured Party in writing
of any change in Borrower's location. The Borrower's Internal Revenue Service
Taxpayer Identification Number is 46-0460145, and the Borrower shall use such
number as its exclusive Internal Revenue Service Taxpayer Identification Number
until all of its Obligations under this Agreement are satisfied in full. The
Borrower will not change its name as incorporated, without the Secured Party's
prior written consent, which may be conditioned upon the Borrower signing
amendments to UCC-1s or other documents as the Secured Party may require.
Borrower is not engaged in and will not engage in farming or growing crops.

     3. Borrower has or will acquire title to and will at all times keep the
Collateral free of all liens and encumbrances, except the security interest
created hereby and has full power and authority to execute this Security
Agreement, to perform Borrower's obligations hereunder and to subject the
Collateral to the security interest created hereby. Borrower will pay all fees,
assessments, charges or taxes arising with respect to the Collateral. There is
no encumbrance or security interest with respect to all or any part of the
Collateral. All costs of keeping the Collateral free of encumbrances and
security interests prohibited by this Agreement and of removing same if they
should arise shall be the obligation of the Borrower, and such obligation shall
be part of the Secured Obligations.

     4. Each right to payment and each instrument, document, chattel paper and
other agreement constituting or evidencing Collateral is (or will be when
arising or issued) a valid, genuine and legally enforceable obligation, subject
to no defense, set-off or counterclaim (other than those arising in the ordinary
course of business) of the account debtor or other obligor named therein or in
Borrower's records pertaining thereto as being obligated to pay such obligation.
Borrower will not agree to any material modification, amendment or cancellation
of any such obligation without Secured Party's prior written consent, and will
not subordinate any such right to payment to claims of other creditors of such
account debtor or other obligor.

     5. Borrower will at any time or times hereafter execute such financing
statements and other documents and instruments and perform such acts as the
Secured Party may from time to time request to establish, maintain, perfect and
enforce a valid security interest in the Collateral, and will pay all costs of
filing and recording. Borrower irrevocably authorizes the Secured Party at any
time and from time to time to file in any Uniform Commercial Code jurisdiction
any initial financing statements and amendments thereto that (a) indicate the
Collateral (i) as all assets of the Borrower or words of similar effect,
regardless of whether any particular asset comprised in the Collateral falls
within the scope of Article 9 of the Uniform Commercial Code of the State or
such jurisdiction, or (ii) as being of an equal or lesser scope or with greater
detail, and (b) contain any other information required by part 5 of Article 9 of
the Uniform Commercial Code of the State for the sufficiency or filing office
acceptance of any financing statement or amendment, including (i) whether the
Borrower is an organization, the type of organization and any organization
identification number issued to the Borrower and, (ii) in the case of a
financing statement, filed as a fixture filing or indicating Collateral as
as-extracted collateral or timber to be cut, a sufficient description of real
property to which the Collateral relates. The Borrower agrees to furnish any
such information to the Secured Party promptly. In the event the Borrower owns
any right in a commercial tort claim (as

<Page>

defined by the UCC), Borrower shall so inform Secured Party and will sign any
additional documentation granting Secured Party a security interest therein as
Secured Party may require.

     6. Borrower will maintain business interruption insurance and keep all
tangible Collateral and all lands, plants, buildings and other property now or
hereafter owned or used in connection with its business in good condition,
normal depreciation excepted, and insured against loss or damage by fire
(including so-called extended coverage), theft, physical damage, and against
such other risks, including without limitation public liability, in such
amounts, with such insurers and upon such terms as Secured Party may reasonably
require. Borrower will include Secured Party as an additional insured and obtain
loss payable indorsements on applicable insurance policies in favor of Borrower
and Secured Party as their interests may appear and at Secured Party's request
will deposit the insurance policies with Secured Party. Borrower shall cause
each insurer to agree, by Policy indorsement or by issuance of a Certificate of
Insurance or by independent instrument furnished to Secured Party, that such
insurer will give 30 days' written notice to Secured Party before such policy
will be altered or canceled. Borrower irrevocably appoints Secured Party as
Borrower's attorney in fact to make claim for, to negotiate settlement of
claims, to receive payment for and to execute and endorse any documents, checks
or other instruments in payment for loss, theft, or damage under any insurance
policy covering the Collateral.

     7. Borrower will promptly notify Secured Party of any loss or material
damage to any Collateral or of any adverse change, known to Borrower, in the
prospect of payment of any sums due on or under any instrument, chattel paper,
account or general intangible constituting Collateral.

     8. Upon Secured Party's request (whether a Default as hereinafter defined,
has occurred) Borrower will promptly deliver to Secured Party any instrument,
document or chattel paper constituting Collateral.

     9. Upon Default by Borrower in performance of its obligation hereunder,
Secured Party shall have the authority, but shall not be obligated to: (i)
effect such insurance and necessary repairs and pay the premiums therefor and
the costs thereof; and (ii) pay and discharge any fees, assessments, charges,
taxes, liens and encumbrances on the Collateral. All sums so advanced or paid by
the Secured Party shall be payable by Borrower on demand with interest at the
highest rate then charged on the Secured Obligations (but not exceeding the
maximum rate allowed by law) and shall be a part of the Secured Obligations.

<Page>

     10. Borrower will not sell, lease or otherwise dispose of the Collateral
other than in the ordinary course of its business at prices constituting the
then fair market value thereof.

     11. The Secured Party shall have the authority (whether or not a Default
has occurred) but shall not be obligated to: (a) notify any or all account
debtors and obligors on instruments constituting Collateral of the existence of
the Secured Party's security interest and if a Default has occurred to pay or
remit all sums due or to become due directly to the Secured Party or its
nominee; (b) place on any chattel paper received as proceeds or otherwise
constituting Collateral, a notation or legend showing the Secured Party's
security interest; (c) if a Default has occurred, in the name of the Borrower or
otherwise, to demand, collect, receive and receipt for, compound, compromise,
settle, prosecute and discontinue any suits or proceedings in respect of any or
all of the Collateral; (d) if a Default has occurred, take any action which the
Secured Party may deem necessary or desirable in order to realize on the
Collateral, including, without limitation, the power to perform any contract, to
indorse in the name of Borrower any checks, drafts, notes or other instruments
or documents received in payment of or on account of the Collateral; (e) to
place upon Borrower's books and records relating to the accounts and general
intangibles covered by the security interest granted hereby a notation or legend
stating that such account or general intangible is subject to a security
interest held by the Secured Party; and (f) after any Default, to enter upon and
into and take possession of all or such part(s) of the properties of Borrower,
including lands, plants, buildings, machinery, equipment and other property as
may be necessary or appropriate in the judgment of the Secured Party to permit
or enable the Secured Party to manufacture, produce, process, store or sell or
complete the manufacture, production, processing, storing or sale of all or any
part of the Collateral, as the Secured Party may elect, and to use and operate
said properties for said purposes and for such length of time as the Secured
Party may deem necessary or appropriate for said purposes without the payment of
any compensation to Borrower thereof.

     12. Borrower will, if a Default has occurred and upon receipt of request
from Secured Party, notify all account debtors and other obligors of the
existence of the Secured Party's security interest and direct such account
debtors and other obligors to pay or remit all sums due or to become due
directly to the Secured Party or its nominee. Borrower will hold all of the
proceeds of any collections and all returned and repossessed goods thereafter
received by Borrower in trust for the Secured Party, and will not commingle the
same with any other funds or property of the Borrower, and will deliver the same
forthwith to the Secured Party at its request.

<Page>

     13. Borrower will keep accurate books, records and accounts with respect to
the Collateral, and with respect to the general business of Borrower, and will
make the same available to the Secured Party at its request for examination and
inspection; and will make and render to the Secured Party such reports,
accountings and statements as the Secured Party from time to time may request
with respect to the Collateral; and will permit any authorized representative of
the Secured Party to examine and inspect during normal business hours, any and
all premises where the Collateral is or may be kept or located.

     14. The occurrence of any of the events identified as a "Default" or "Event
of Default" under the Loan Agreement will constitute a Default hereunder.

     15. Whenever a Default shall exist, the Secured Party may, at its option
and without demand or notice, except to the extent notice is required under the
Loan Agreement, declare all or any part of the Secured Obligations immediately
due and payable, and the Secured Party may exercise, in addition to the rights
and remedies granted hereby, all rights and remedies of a secured party under
the Uniform Commercial Code or any other applicable law. The Secured Party shall
be entitled to recover its attorneys' fees, service tax thereon, and all costs
incurred by such attorneys, to the extent permitted by law.

     16. Borrower agrees, in the event of Default, to make the Collateral
available to the Secured Party at a place or places to be designated by the
Secured Party, which is reasonably convenient to both parties, and to pay all
costs of the Secured Party, including reasonable attorneys' fees, service tax
thereon, and all costs incurred by such attorneys, in the collection of any of
the Secured Obligations and the enforcement of any of the Secured Party's
rights. If any notification of intended disposition of any of the Collateral is
required by law, such notification shall be deemed properly given if mailed a
reasonable time before such disposition, postage prepaid, addressed to the
Borrower at the address shown above. Secured Party's duty of care with respect
to Collateral in its possession shall be deemed fulfilled if Secured Party
exercises reasonable care in physically safekeeping such Collateral or, in the
case of Collateral in the custody or possession of a bailee or other third
person, exercises reasonable care in the selection of the bailee or other third
person, and Secured Party need not otherwise preserve, protect, insure or care
for any Collateral. Secured Party shall not be obligated to preserve any rights
Borrower may have against prior parties, to realize on the Collateral at all or
in any particular manner or order, or to apply any cash proceeds of Collateral
in any particular order of application. No delay or failure by the Secured Party
in the exercise of any right or remedy shall constitute a waiver thereof, and no
single or partial exercise by the

<Page>

Secured Party of any right or remedy shall preclude other or further exercise
thereof or the exercise of any other right or remedy.

     17.   This Agreement is governed by the laws of the State of South Dakota
without regard to its conflict of law provisions.
