portion thereof) of principal or interest on the Notes, when due, and the
Guarantor shall immediately pay the same to the Lender, and the Lender may
demand payment or performance of any or all of the other Obligations, when such
payment or performance is due or required and the Guarantor shall immediately

foreclosure of any security interest, mortgage or 

 

1

 

other
lien in, any or all of the collateral securing the Obligations; or (4) otherwise
exercised its rights and remedies hereunder or under the Obligations, the

4.                                       Agrees that the Lender may,
from time to time, without notice to the Guarantor, which notice is hereby
waived by the Guarantor, extend, modify, renew or compromise the Obligations,
in whole or in part, without releasing, extinguishing or affecting in any
manner whatsoever the liability of Guarantor hereunder, the foregoing acts
being hereby consented to by the Guarantor.

 

5.                                       Agrees that the Lender shall
not be required to first resort for payment to the Borrower or any other
person, corporation or entity, or their properties or estate, or any other
right or remedy whatsoever, prior to enforcing this Guaranty.

 

6.                                       Agrees that this Guaranty
shall be construed as a continuing, absolute, and unconditional guaranty
without regard to (a) the validity, regularity or enforceability of the
Obligations or the disaffirmance thereof in any insolvency or bankruptcy
proceeding relating to the Borrower; or (b) any event or any conduct or
action of the Borrower or the Lender or any other party which might otherwise
constitute a legal or equitable discharge of a surety or guarantor but for this
provision.

 

7.                                       Agrees that this Guaranty

8.                                       Agrees that the Lender is
expressly authorized to forward or deliver any or all collateral and security
which may, at any time, be placed with it by the Borrower, the Guarantor or any
other person, directly to the Borrower for collection and remittance or for
credit, or to collect the same in any other manner and to renew, extend,
compromise, exchange, release, surrender or modify the installments of, any or
all of such collateral and security with or without consideration and without
notice to the Guarantor and without in any manner affecting the absolute
liability of the Guarantor hereunder; and that the liability of the Guarantor
hereunder shall not be affected or impaired by any failure, neglect or omission
on the part of the Lender to realize upon the Obligations, or upon any
collateral or security therefore, nor by the taking by the Lender of any other
guaranty or guaranties to secure the Obligations or any other indebtedness of
the Borrower to the Lender, nor by the taking by the Lender of collateral or
security of any kind nor by any act or failure to act whatsoever which, but for
this provision, might or could in law or in equity act to release or reduce the
Guarantor’s liability hereunder.

 

9.                                       Agrees that notwithstanding
any payment or payments made by the Guarantor hereunder or any setoff or
application of funds of the Guarantor by the Lender, the Guarantor shall 

 

2

 

not be entitled to be subrogated to any of the rights of the Lender
against the Borrower or any other guarantor or any collateral security or guaranty
or right of offset held by the Lender for the payment of the Obligations, nor
shall the Guarantor seek or be entitled to seek any contribution or
reimbursement from the Borrower or any other guarantor in respect of payments
made by the Guarantor hereunder, until all amounts owing to the Lender by the
Borrower and on account of the Obligations are paid in full.  Notwithstanding any of the foregoing, to the
extent (a) any right of subrogation which the Guarantor may have pursuant
to this Guaranty or otherwise, or (b) any right of reimbursement or
contribution or similar right against the Borrower, any property of the
Borrower or any other guarantor of any of the Obligations would result in the
Guarantor being “creditors” of or the holders of a “claim” against the Borrower
within the meaning of Title 11 of the United States Bankruptcy Code as now in
effect or hereafter amended, or any comparable provision of any successor
statute, the Guarantor hereby irrevocably waives such right of subrogation,
reimbursement or contribution.

 

10.                                 Agrees that the liability of
the Guarantor hereunder shall not be affected or impaired by the existence or
creation from time to time, with or without notice to the Guarantor, which
notice is hereby waived, of indebtedness from the Borrower to the lender in
addition to the indebtedness evidenced by the Notes; the creation or existence
of such additional indebtedness being hereby consented to by the Guarantor.

 

11.                                 Agrees that the possession
of this instrument of guaranty by the Lender shall be conclusive evidence of
due execution and delivery hereof by the Guarantor.

 

12.                                 Agrees that this Guaranty
shall be binding upon the legal representative, successors and assigns of the
Guarantor, and shall inure to the benefit of the Lender and its successors,
assigns and legal representative; that notwithstanding the foregoing, the
Guarantor shall have no right to assign or otherwise transfer their rights and
obligations under this Guaranty to any third party without the prior written
consent of the Lender; and that any such assignment or transfer shall not
release or affect the liability of the Guarantor hereunder in any manner
whatsoever.

 

13.                                 Agrees that the Guarantor
may be joined in any action or proceeding commenced against the Borrower in connection
with or based upon the Obligations and recovery may be had against the
Guarantor in any such action or proceeding or in any independent action or
proceeding against the Guarantor should the Borrower fail to duly and
punctually pay any of the principal of or interest on the Obligations without
any requirement that the Lender first assert, prosecute or exhaust any remedy
or claim against the Borrower.

 

14.                                 Agrees that upon the
occurrence at any time of an Event of Default (as defined in the Credit Agreement),
the Lender shall have the right to set off any and all amounts due hereunder by
the Guarantor to the Lender against any indebtedness or obligation of the
Lender to the Guarantor.

 

15.                                 Agrees that the Guarantor
shall be liable to the Lender for any deficiency remaining after foreclosure of
any mortgage on real estate or any security interest in personal property
granted 

 

3

 

by the Borrower, the Guarantor or any third party to the Lender to
secure repayment of the Obligations and the subsequent sale by the Lender of
the property subject thereto to a third party (whether at a foreclosure sale or
at a sale thereafter by the Lender in the event the Lender purchases said
property at the foreclosure sale) notwithstanding any provision of applicable
law which may prevent the Lender from obtaining a deficiency judgment against,
or otherwise collecting a deficiency from, the Borrower, including without
limitation, Minnesota Statutes Section 580.23.

 

16.                                 Agrees that this Guaranty
shall be deemed a contract made under and pursuant to the laws of the State of
Minnesota and shall be governed by and construed under the laws of such state;
and that, wherever possible, each provision of this Guaranty shall be interpreted
in such a manner as to be effective and valid under applicable law, but if any
provisions of this Guaranty shall be prohibited by or invalid under applicable
law, such provision shall be ineffective only to the extent of such prohibition
or invalidity without invalidating the remainder of such provision or the
remaining provisions of the Guaranty.

 

17.                                 Agrees that no failure on
the part of the Lender to exercise, and no delay in exercising, any right or
remedy hereunder shall operate as or constitute a waiver thereof; nor shall any
single or partial exercise of any right or remedy hereunder preclude any other
or further exercise thereof or the exercise of any other right or remedy
granted hereby or by any related document or by law.

 

18.                                 Agrees to deliver
to the Lender, as soon as available and in any event within one hundred twenty
(120) days after the end of Guarantor’s fiscal year ending December 31,
2006, and for each succeeding fiscal year, a copy of the audited financial
statements (including balance sheet, statements of income and cash flows, all
accompanying notes thereto and any management letter), for such year for the
Guarantor, certified, without qualification, in an opinion acceptable to the
Lender by independent certified public accountants of recognized standing
selected by the Guarantor and acceptable to the Lender, and the federal and
state income tax returns and schedules of the Guarantor, or copies of all
extensions for such returns and returns within 30 days of filing.  In addition, Guarantor agrees with reasonable
promptness, to provide to Lender such further information regarding the
business, operations, affairs and financial and other condition of the
Guarantor as the Lender may reasonably request.

 

19.                                 Waives any and
all claims against the Lender and defenses to performance and payment hereunder
relating in any way, directly or indirectly, to the performance of the Lender’s
obligations or exercise of any of its rights under the Notes and the documents
related thereto.

 

20.                                 Warrants and
represents to the Lender as follows:

 

a.                                       Enforceability.  This Guaranty constitutes the legal, valid
and binding obligation of the Guarantor enforceable in accordance with its
terms (subject, as to enforceability, to limitations resulting from bankruptcy,
insolvency or other similar laws affecting creditors’ rights generally).

 

4

 

b.                                      Litigation.  There is no action, suit or proceeding, other
than the Permit Litigation, pending or, to the knowledge of the Guarantor,
threatened against or affecting the Guarantor which, if adversely determined,
would have a material adverse effect on the condition (financial or otherwise),
property or assets of the Guarantor, or which would question the validity of
this Guaranty or any instrument, document or other agreement related hereto or
required hereby, or impair the ability of the Guarantor to perform their
obligations hereunder or thereunder.

 

c.                                       Default.  Guarantor is not in default of a material
provision under any material agreement, instrument, decree or order to which
they are parties or by which they or their property is bound or affected.

 

d.                                      Consents.  No consent, approval, order or authorization
, registration, declaration or filing with, or notice to, any governmental
authority or any third party is required in connection with the execution and
delivery of this Guaranty or any of the agreements or instruments herein
mentioned to which Guarantor is a party or the carrying out or performance of
any of the transactions required or contemplated hereby or thereby or, if
required, such consent, approval, order or authorization has been obtained or
such registration, declaration or filing has been accomplished or such notice
has been given prior to the date hereof.

 

e.                                       Taxes.  Guarantor has filed all tax returns required
to be filed and have paid all taxes shown thereon to be due, including interest
and penalties, which are not being contested in good faith and by appropriate
proceedings and none of them has any information or knowledge of any objections
to or claims for additional taxes in respect of federal income or excess
profits tax returns for prior years.

 

21.                                 Agrees that (a) the
Guarantor will indirectly benefit by and from the making of the loan by the
Lender to the Borrower evidenced by the Notes by virtue of the fact that the
Guarantor is a subsidiary of the Borrower and the Borrower is the sole member of
the Guarantor; (b) the Guarantor has received legal and adequate
consideration for the execution of this Guaranty and has executed and delivered
this Guaranty to the Lender in good faith in exchange for reasonably equivalent
value; (c) the Guarantor is not presently insolvent and will not be
rendered insolvent by virtue of the execution and delivery of this Guaranty; (d) the
Guarantor has not executed or delivered this Guaranty with actual intent to
hinder, delay or defraud the Guarantor’s creditors; and (e) the Lender has
agreed to make such loan in reliance upon this Guaranty.

 

22.                                 Agrees that if, at any time,
all or any part of any payment previously applied by the Lender to any of the
Obligations must be returned by the Lender for any reason, whether by court
order, administrative order or settlement, the Guarantor shall remain liable
for the full amount returned as if said amount had never been received by the
Lender, notwithstanding any term of this Guaranty or the cancellation or return
of any note or other agreement evidencing the Obligations.

 

5

 

23.                                 Agrees that (a) the
Guarantor irrevocably submits to the jurisdiction of any Minnesota state court
or federal court over any action or proceeding arising out of or relating to
the Notes, the Credit Agreement, and any instrument, agreement or document
related thereto; (b) all claims in respect of such action or proceeding
may be heard and determined in such Minnesota state or federal court; (c) the
Guarantor irrevocably waives, to the fullest extent they may effectively do so,
the defense of an inconvenient forum to the maintenance of such action or
proceeding; (d) the Guarantor irrevocably consent to the service of copies
of the Summons and Complaint and any other process which may be served in any
such action or proceeding by the mailing by United States certified mail,
return receipt requested, of copies of such process to the Guarantor’s last
known addresses; (e)  judgment final by appeal, or expiration of time to
appeal without an appeal being taken, in any such action or proceeding shall be
conclusive and may be enforced in any other jurisdictions by suit on the
judgment or in any other manner provided by law; and (f) nothing in this
Paragraph shall affect the right of the Lender to serve legal process in any
other manner permitted by law or affect the right of Lender to bring any action
or proceeding against the Guarantor or their property in the courts of any
other jurisdiction to the extent permitted by law.

for Advances Irrevocable.  Each Request for Advance shall be irrevocable
and binding on the Borrower and the Borrower shall indemnify the Lender against
any loss or expense it may incur as a result of any failure to borrow any
Advance after a Request for Advance (including any failure resulting from the
failure to fulfill on or before the date specified for such Advance the
applicable conditions set forth in Article III of this Fifth Supplement),
including, without limitation, any loss (including loss of anticipated profits)
or expense incurred by reason of the liquidation or reemployment of deposits or
other funds acquired by the Lender to fund such Advance when such Advance, as a
result of such failure, is not made on such date.

 

(c)                                  Minimum
Amounts.  Each
Revolving Advance shall be in a minimum amount equal to $10,000.00.

 

(d)                                 Unused
Commitment  Fee.  Borrower agrees to pay to the Lender an
Unused Commitment Fee on the average daily unused portion of the Revolving Line
of Credit Loan Commitment from the effective date of this Agreement until the Revolving
Line of Credit Loan Maturity Date.  Such
Unused Commitment Fee shall be equal to a rate of 0.25% per annum, payable in
arrears in quarterly installments on the first (1st) day of each
third month after the effective date of this Agreement.

 

(e)                                  Draft
Loan Program.  At the
Borrower’s request and at the Lender’s sole discretion, the Borrower may obtain
a Revolving Advance by using draft forms furnished by the Lender to the
Borrower, subject to the following terms and conditions:

 

(i)                                     Borrower Authorization
and Responsibility.  The Borrower
shall be deemed to have authorized and directed the Lender and its duly
authorized agents to accept drafts and to disburse Revolving Line of Credit
Loan funds by due execution of any draft. 
The Borrower shall be responsible for all disbursements made pursuant to
this authorization and direction.  The
Lender shall not be obligated to inquire as to whether the Borrower has issued
specific directions for any particular draft or to determine whether the
Borrower has received the benefit of the proceeds of any particular draft
before honoring such draft.  The
execution of any draft by the Borrower shall constitute a representation and
warranty to the Lender that the conditions set forth in Section 6(e) have
been met as of the date of all such drafts.

 

4

 

(ii)                                  Minimum Amount.  Each draft shall be in a minimum amount equal
to $10,000.00 and shall not be written in excess of the Revolving Line of
Credit Loan Commitment provided, however; that
at no time shall any draft be written that results in the Outstanding Revolving
Advance exceeding the Borrowing Base or the Revolving Line of Credit Loan Commitment,
whichever is less.

 

(iii)                               Stop Payment
Provisions.  The
Borrower may stop payment on a draft by written request to the Lender.  The Lender shall not be liable in the event
the draft is honored following a stop-payment order, if such order is not
received in sufficient time to permit the dishonor.  The Borrower shall reimburse the Lender for
all damages, costs and expenses as a result of the Lender’s refusal to honor a
draft due to a stop payment order requested by the Borrower.

 

(iv)                              Fees.  Reasonable fees may be charged the Borrower
by Lender for the use of drafts and are subject to change at the Lender’s
discretion.  In addition, the Borrower
may be charged additional fees for each draft that is not in compliance with
the provisions set forth in this Section 6(d) and for any draft for
which the Borrower requests a stop-payment order.

 

(v)                                 Limitations.  The Borrower shall not issue any draft as
payment on this or other Loan Obligations of the Borrower or for any purpose
other than as permitted in the Loan Documents.

 

(vi)                              Revocation of
Rights and Rejection of Drafts.  The Lender reserves the right to revoke all
future draft privileges without notice to the Borrower in the event the payment
of any draft would result in the Outstanding Revolving Advance exceeding the
Borrowing Base or the Revolving Line of Credit Loan commitment, whichever is
less.  The Lender reserves the right to
reject drafts that are not written for purposes specified in or pursuant to the
terms and conditions of the Loan Documents. 
In the event that Lender chooses to honor a draft which exceeds the
limits as set forth in this Section 6(d)(ii), Borrower shall repay all the
amounts by which the Outstanding Revolving Advances exceed the Borrowing Base
or the Revolving Line of Credit Loan Commitment, whichever is less, plus
interest and a reasonable overdraft fee, upon demand by Lender.

 

(vii)                           Notification.  The Borrower agrees to immediately notify the
Lender in the event one or more drafts are lost, stolen, destroyed or otherwise
misused and to indemnify the Lender and hold the Lender harmless from any loss
or claim if any draft is lost, stolen, forged, altered or otherwise misused.

 

(viii)                        Authorization.  This authorization and direction shall be
effective until the Lender receives written notice of revocation by the
Borrower, provided the privilege of using drafts may be terminated by the
Lender at any time in its sole discretion. 
Upon such termination, the Borrower shall surrender to the Lender all
unused drafts on demand.

 

(f)                                    Conditions
Precedent to All Advances.  The Lender’s obligation to make each Advance
under the Revolving Line of Credit Note shall be subject to the terms,
conditions and covenants set forth in the MLA and this Fifth Supplement,
including, without limitation, the following further conditions precedent:

 

(i)                                     Representations
and Warranties.  The
representations and warranties set forth in the MLA and this Fifth Supplement
are true and correct in all material respects as of the date of the request for
any Advance to the same extent and with the same effect as if made at and as of
the date thereof except as disclosed in writing to the Lender;

 

5

 

(ii)                                  Compliance With
Disbursing Agreement.  All of the
terms and conditions of the Disbursing Agreement have been satisfied with
respect to each such Advance;

 

(iii)                               No Defaults.  The Borrower is not in default under the
terms of the MLA, the Related Documents or any other Material Contracts to
which the Borrower is a party and which relates to the construction of the
Project or the operation of the Borrower’s business; and

 

7.                                      Letters
of Credit.

 

(a)                                  Commitment
to Issue.  The
Borrower may request Revolving Advances by the Lender, and the Lender, subject
to the terms and conditions of this Fifth Supplement, may, in its sole
discretion, issue letters of credit for any Borrower’s account (such letters of
credit, being hereinafter referred to collectively as the “Letters of
Credit”); provided, however,
that:

 

(i)                                     the aggregate
amount of outstanding Letter of Credit Liabilities shall not at any time exceed
the amount of $500,000.00;

 

(ii)                                  the sum of the
outstanding Letters of Credit plus the Outstanding Revolving Advances shall not
at any time exceed the Borrowing Base.

 

(b)                                 Letter
of Credit Request Procedure.  The Borrower shall give the Lender
irrevocable prior notice (effective upon receipt) on or before 3:00 P.M.
(Minneapolis, Minnesota time) on the Business Day three Business Days prior to
the date of the requested issuance of a Letter of Credit specifying the requested
amount, expiry date and issuance date of each Letter of Credit to be issued and
the nature of the transactions to be supported thereby.  Any such notice received after 3:00 P.M.
(Minneapolis, Minnesota time) on a Business Day shall be deemed to have been
received and be effective on the next Business Day.  Each Letter of Credit shall be in the form of
Exhibit B to this Fifth Supplement, have an expiration date that occurs on
or before the Maturity Date, shall be payable in U.S. dollars, must be satisfactory
in form and substance to the Lender, and shall be issued pursuant to such
documentation as the Lender may require, including, without limitation, the
Lender’s standard form letter of credit request and reimbursement Fifth
Supplement; provided that, in the event of any
conflict between the terms of such Fifth Supplement and the other Loan
Documents, the terms of the other Loan Documents shall control.

 

(c)                                  Letter
of Credit Fees.  The
Borrower shall pay to the Lender for (i) all fees, costs, and expenses of
the Lender arising in connection with any Letter of Credit, including the
Lender’s customary fees for amendments, transfers, and drawings on Letters of
Credit and (ii) on the date of the issuance of the Letter of Credit, and
at the anniversary date of issuance of such Letter of Credit, an issuance fee
equal to two and one-half (2.5%) percent, on an annualized basis, of the
maximum amount available to be drawn under the Letter of Credit.

 

(d)                                 Funding
of Drawings.  Upon
receipt from the beneficiary of any Letter of Credit of any demand for payment
or other drawing under such Letter of Credit, the Issuer shall promptly notify
the Borrower as to the amount to be paid as a result of such demand or drawing
and the respective payment date.  Any
notice pursuant to the forgoing sentence shall specify the amount to be paid as
a result of such demand or drawing and the respective payment date.

 

(e)                                  Reimbursements.  After receipt of the notice delivered
pursuant to clause (d) of this section  with respect to a Letter
of Credit, the Borrower shall be irrevocably and unconditionally obligated to
reimburse the Lender for any amounts paid by the Lender upon any demand for
payment or 

 

6

 

drawing under the applicable Letter of Credit, without presentment,
demand, protest, or other formalities of any kind other than the notice
required by clause (d) of this section.  Such 
reimbursement shall occur no later than 3:00 P.M. (Minneapolis,
Minnesota time) on the date of payment under the applicable Letter of Credit if
the notice under clause (d) of this section is received by 2:00 P.M.
(Minneapolis, Minnesota time) on such date or by 11:00 A.M. (Minneapolis,
Minnesota time) on the next Business Day, if such notice is received after 2:00 P.M.
(Minneapolis, Minnesota time).  All
payments on the Reimbursement Obligations (including any interest earned
thereon) shall be made to the Lender for the account of the Lender in U.S.
dollars and in immediately available funds, without set-off, deduction, or
counterclaim.

 

(f)                                    Reimbursement Obligations Absolute.  The
Reimbursement Obligations of the Borrower under this Fifth Supplement shall be
absolute, unconditional, and irrevocable, and shall be performed strictly in
accordance with the terms of the Loan Documents under all circumstances
whatsoever and the Borrower hereby waives any defense to the payment of the
Reimbursement Obligations based on any circumstance whatsoever, including,
without limitation, in any case, the following circumstances:  (i) any lack of validity or
enforceability of any Letter of Credit or any other Loan Document; (ii) any
amendment or waiver of or any consent to departure from any Loan Document; (iii) the
existence of any claim, set-off, counterclaim, defense, or other rights which
any Borrower or any other Person may have at any time against any beneficiary
of any Letter of Credit, the Lender or any other Person, whether in connection
with any Loan Document or any unrelated transaction; (iv) any statement,
draft, or other documentation presented under any Letter of Credit proving to
be forged, fraudulent, invalid, or insufficient in any respect or any statement
therein being untrue or inaccurate in any respect whatsoever; (v) payment
by the Lender under any Letter of Credit against presentation of a draft or
other document that does not comply with the terms of such Letter of Credit; or
(vi) any other circumstance whatsoever, whether or not similar to any of
the foregoing; provided that Reimbursement
Obligations with respect to a Letter of Credit may be subject to avoidance by a
Borrower if the Borrower proves in a final non-appealable judgment that it was
damaged and that such damage arose directly from the Lender’s willful
misconduct or gross negligence in determining whether the documentation
presented under the Letter of Credit in question complied with the terms
thereof.

 

(g)                                 Issuer
Responsibility.  Borrower
assumes all risks of the acts or omissions of any beneficiary of any Letter of
Credit with respect to its use of such Letter of Credit.  Neither the Lender, nor any of its respective
officers or directors shall have any responsibility or liability to the
Borrower or any other Person for:  (a) the
failure of any draft to bear any reference or adequate reference to any Letter
of Credit, or the failure of any documents to accompany any draft at
negotiation, or the failure of any Person to surrender or to take up any Letter
of Credit or to send documents apart from drafts as required by the terms of
any Letter of Credit, or the failure of any Person to note the amount of any
instrument on any Letter of Credit, each of which requirements, if contained in
any Letter of Credit itself, it is agreed may be waived by the Lender; (b) errors,
omissions, interruptions, or delays in transmission or delivery of any
messages; (c) the validity, sufficiency, or genuineness of any draft or
other document, or any endorsement(s) thereon, even if any such draft,
document or endorsement should in fact prove to be in any and all respects
invalid, insufficient, fraudulent, or forged or any statement therein is untrue
or inaccurate in any respect; (d) the payment by the Lender to the
beneficiary of any Letter of Credit against presentation of any draft or other
document that does not comply with the terms of the Letter of Credit; or (e) any
other circumstance whatsoever in making or failing to make any payment under a
Letter of Credit.  The Lender may accept
documents that appear on their face to be in order, without responsibility for
further investigation, regardless of any notice or information to the contrary.

 

8.                                      Interest Rate.  Subject to the
provisions of Sections 9 and 11 of this Fifth Supplement, the Revolving Line of
Credit Loan shall bear interest at a rate equal to the LIBOR Rate plus 325
basis points.  The computation of
interest, amortization, maturity and other terms and conditions of the Revolving
Line of Credit Loan shall be as provided in the Revolving Line of Credit Note,
provided, 

 

7

 

however,
in no event shall the applicable rate exceed the maximum nonusurious interest
rate, if any, that at any time, or from time to time, may be contracted for,
taken, reserved, charged, or received under applicable state or federal laws
(the “Maximum Rate”).

 

9.                                      Default Interest.  In addition to the rights and remedies set
forth in the MLA:  (i) if the
Borrower fails to make any payment to Lender when due (including, without
limitation, any purchase of equity of Lender when required), then at Lender’s
option in each instance, such obligation or payment shall bear interest from
the date due to the date paid at 2% per annum in excess of the rate of interest
that would otherwise be applicable to such obligation or payment; (ii) upon
the occurrence and during the continuance of an Event of Default beyond any
applicable cure period, if any, at Lender’s option in each instance, the unpaid
balances of the Revolving Line of Credit Loan shall bear interest from the date
of the Event of Default or such later date as Lender shall elect at 2% per
annum in excess of the rate(s) of interest that would otherwise be in
effect on the Revolving Line of Credit Loan under the terms of the Revolving
Line of Credit Note; (iii) after the maturity of the Revolving Line of
Credit Loan, whether by reason of acceleration or otherwise, the unpaid
principal balance of the Revolving Line of Credit Loan (including without
limitation, principal, interest, fees and expenses) shall automatically bear
interest at 2% per annum in excess of the rate of interest that would otherwise
be in effect on the Revolving Line of Credit Loan under the terms of the Revolving
Line of Credit Note.  Interest payable at
the Default Rate shall be payable from time to time on demand or, if not sooner
demanded, on the last day of each calendar month.

 

10.                               Late Charge.  If
any payment of principal or interest due under this Fifth Supplement or the Revolving
Line of Credit Note is not paid within ten (10) days of the due date
thereof, the Borrower shall, in addition to such amount, pay a late charge
equal to five percent (5%) of the amount of such payment.

 

11.                               Changes in Law Rendering Certain LIBOR Rate Loans Unlawful.  In the event that any change in any
applicable law (including the adoption of any new applicable law) or any change
in the interpretation of any applicable law by any judicial, governmental or
other regulatory body charged with the interpretation, implementation or
administration thereof, should make it (or in the good-faith judgment of the
Lender should raise a substantial question as to whether it is) unlawful for
the Lender to make, maintain or fund LIBOR Rate Loans, then:  (a) the Lender shall promptly notify
each of the other parties hereto; and (b) the obligation of the Lender to
make LIBOR rate loans of such type shall, upon the effectiveness of such event,
be suspended for the duration of such unlawfulness.  During the period of any suspension, Lender
shall make loans to Borrower that are deemed lawful and that as closely as
possible reflect the terms of the MLA.

 

12.                               Payments and Computations.

 

(a)                                  Method
of Payment.  Except as
otherwise expressly provided herein, all payments of principal, interest, and
other amounts to be made by the Borrower under the Loan Documents shall be made
to the Lender in U.S. dollars and in immediately available funds, without
set-off, deduction, or counterclaim, not later than 2:00 P.M.
(Minneapolis, Minnesota time) on the date on which such payment shall become
due (each such payment made after such time on such due date to be deemed to
have been made on the next succeeding Business Day).  The Borrower shall, at the time of making
each such payment, specify to the Lender the sums payable under the Loan
Documents to which such payment is to be applied and in the event that the
Borrower fail to so specify or if an Event of Default exists, the Lender  may apply such payment and any proceeds of
any Collateral to the Loan Obligations in such order and manner as it may elect
in its sole discretion, subject to Section 12(c).

 

8

 

(b)                                 Application
of Funds.  Apply all
payments received by it to the Borrower’s obligations to Lender in such order
and manner as Lender may elect in its sole discretion; provided that any
payments received from any guarantor or from any disposition of any collateral
provided by such guarantor shall only be applied against obligations guaranteed
by such guarantor.

 

(c)                                  Payments
on a Non-Business Day. 
Whenever any payment under any Loan Document shall be stated to be due
on a day that is not a Business Day, such payment may be made on the next
succeeding Business Day, and such extension of time shall in such case be
included in the computation of the payment of interest and fees, as the case may
be.

 

(d)                                 Proceeds
of Collateral.  All
proceeds received by the Lender from the sale or other liquidation of the
Collateral when an Event of Default exists shall first be applied as payment of
the accrued and unpaid fees and expenses of the Lender hereunder and then to
all other unpaid or unreimbursed Loan Obligations (including reasonable
attorneys’ fees and expenses) owing to the Lender and then any remaining amount
of such proceeds shall be applied to the unpaid amounts of Loan Obligations,
until all the Loan Obligations have been paid and satisfied in full or cash
collateralized.  After all the Loan
Obligations (including without limitation, all contingent Loan Obligations)
have been paid and satisfied in full, all Commitments terminated and all other
obligations of the Lender to the Borrower otherwise satisfied, any proceeds of
Collateral shall be delivered to the Person entitled thereto as directed by the
Borrower or as otherwise determined by applicable law or applicable court
order.

 

(e)                                  Computations.  Except as expressly provided otherwise herein,
all computations of interest and fees shall be made on the basis of actual
number of days lapsed over a year of 365 or 366 days, as appropriate.  Interest shall accrue from and include the
date of borrowing, but exclude the date of payment.

 

13.                               Maximum
Amount Limitation. 
Anything in this MLA, this Fifth Supplement, or the other Loan Documents
to the contrary notwithstanding, Borrower shall not be required to pay unearned
interest on the Revolving Line of Credit Note or any of the Loan Obligations,
or ever be required to pay interest on the Revolving Line of Credit Note or any
of the Loan Obligations at a rate in excess of the Maximum Rate, if any.  If the effective rate of interest which would
otherwise be payable under the MLA, this Fifth Supplement, the Revolving Line
of Credit Note, or any of the other Loan Documents would exceed the Maximum
Rate, if any, then the rate of interest which would otherwise be contracted
for, charged, or received under the MLA, this Fifth Supplement, the Revolving
Line of Credit Note, or any of the other Loan Documents shall be reduced to the
Maximum Rate, if any.  If any unearned
interest or discount or property that is deemed to constitute interest
(including, without limitation, to the extent that any of the fees payable by
Borrower for the Loan Obligations to the Lender under the MLA, this Fifth
Supplement, the Revolving Line of Credit Note, or any of the other Loan
Documents are deemed to constitute interest) is contracted for, charged, or
received in excess of the Maximum Rate, if any, then such interest in excess of
the Maximum Rate shall be deemed a mistake and canceled, shall not be collected
or collectible, and if paid nonetheless, shall, at the option of the holder of the
Revolving Line of Credit Note, be either refunded to the Borrower, or credited
on the principal of the Revolving Line of Credit Note.  It is further agreed that, without limitation
of the foregoing and to the extent permitted by applicable law, all calculations
of the rate of interest or discount contracted for, charged or received by the
Lender under the Revolving Line of Credit Note, or under any of the Loan
Documents, that are made for the purpose of determining whether such rate
exceeds the Maximum Rate applicable to the Lender, if any, shall be made, to
the extent permitted by applicable laws (now or hereafter enacted), by
amortizing, prorating and spreading during the period of the full terms of the
Advances evidenced by the Revolving Line of Credit Note, and any renewals
thereof all interest at any time contracted for, charged or received by Lender
in connection therewith.  This
section shall control every other provision of all agreements among the
parties to the MLA pertaining to the transactions contemplated by or contained
in the Loan 

 

9

 

Documents, and the terms of this section shall be deemed to be
incorporated in every Loan Document and communication related thereto.

 

14.                               Lender
Records.  All advances
and all payments or prepayments made thereunder on account of principal or
interest may be evidenced by the Lender in accordance with its usual practice
in an account or accounts evidencing such advances and all payments or
prepayments thereunder from time to time and the amounts of principal and
interest payable and paid from time to time thereunder; in any legal action or
proceeding in respect of the Notes, the entries made in such account or
accounts shall be prima  facie evidence of the existence and
amounts of all advances and all payments or prepayments made thereunder on
account of principal or interest.  Lender
shall provide monthly statements of such entries to Borrower for the purpose of
confirming the accuracy of such entries.

 

15.                               Mandatory
Prepayments or Collateralization. The Borrowers shall,
within five (5) days following the earlier of the delivery of each
Borrowing Base Certificate hereof or the day upon which such Borrowing Base
Certificate was due, either (i) prepay the Advances in the amount, if any,
by which the Outstanding Credit on the date of prepayment under this Section 15
exceeds the Borrowing Base at such time, together with accrued interest to the
date of such prepayment on the amount prepaid, or (ii) pledge and assign
to the Lender additional collateral acceptable to the Lender, in the Lender’s
sole discretion, and deliver all documentation that the Lender, in its sole
discretion, may require in connection with such pledge and assignment and the
perfection of a first-priority security interest in such additional collateral,
so that the Borrowing Base plus the value assigned by the Lender, in its sole
discretion, to such additional collateral equals or exceeds the Outstanding
Credit.

 

16.                               Loan
Payments.  During the
continuance of an Event of Default, the Lender may deduct any obligations due
or any other amounts due and payable by the Borrower under the Loan Documents
from any accounts maintained with the Lender.

 

17.                               Reporting
Requirements.  In addition to
the reporting requirements under Section 5.01(c) in the MLA, the
Borrower will furnish to the Lender as soon as available and in any event
within 30 days after the end of each month (or at such other times or with such
greater frequency as is requested by the Lender), a duly completed Borrowing
Base Certificate, setting forth the Borrowing Base as of the last day of such
month calculated based upon collateral value criteria and advance rates which
do not exceed those set forth in the Borrowing Base Certificate, and including
such other information, representation and warranties contemplated therein,
certified by the appropriate authorized officer of the Borrower.

 

18.                               Compensation.  Upon the request of the
Lender, the Borrower shall pay to the Lender such amount or amounts as shall be
sufficient (in the reasonable opinion of the Lender) to compensate it for any
loss, cost, or expense (excluding loss of anticipated profits incurred by it)
as a result of: (i) any payment, prepayment, or conversion of a LIBOR rate
loan for any reason on a date other than the last day of the Interest Period
for such Loan; or (ii) any failure by the Borrower for any reason
(including, without limitation, the failure of any condition precedent
specified in the MLA or this Fifth Supplement to be satisfied) to borrow,
extend, or prepay a LIBOR rate loan on the date for such borrowing, extension,
or prepayment specified in the relevant notice of borrowing, extension or
prepayment under this Agreement.

 

Such indemnification may include any amount equal to the excess, if
any, of:  (a) the amount of interest
which would have accrued on the amount so prepaid, or not so borrowed,
converted or extended, for the period from the date of such prepayment or of
such failure to borrower, convert or extend to the last day of the applicable
Interest Period (or in the case of a failure to borrow, convert or extend, the
Interest Period that would have commenced on the date of such failure) in each
case at the applicable rate of interest for such loan as provided for herein; over
(b) the amount of interest (as reasonably determined 

 

10

 

by the Lender) which would have accrued to the Lender on such amount by
placing such amount on deposit for a comparable period with leading banks in
the interbank LIBOR market. The covenants of the Borrower set forth in this
section shall survive the repayment of the Revolving Line of Credit Loan and
other obligations under the Loan Documents hereunder.

 

19.                               Security.  The Borrower’s obligations hereunder and, to
the extent related thereto, the MLA, shall be secured as provided in the MLA.

 

20.                               Effect
