OBLIGATIONS OF GRANTOR. Grantor warrants and covenants to Lender as follows:

Perfection of Security Interest. ▇▇▇▇▇▇▇ agrees to execute such financing
statements and to take whatever other actions are requested by ▇▇▇▇▇▇ to
perfect and continue ▇▇▇▇▇▇'s security interest in the Collateral. Upon
request of ▇▇▇▇▇▇, Grantor will deliver to Lender any and all of the
documents evidencing or constituting the Collateral, and Grantor will note
▇▇▇▇▇▇'s interest upon any and all chattel paper if not delivered to Lender
for possession by ▇▇▇▇▇▇. Grantor hereby appoints ▇▇▇▇▇▇ as its irrevocable
attorney-in-fact for the purpose of executing any documents necessary to
perfect or to continue the security interest granted in this Agreement.
Lender may at any time, and without further authorization from Grantor,
file a carbon, photographic or other reproduction of any financing
statement or of this Agreement for use as a financing statement. Grantor
will reimburse Lender for all expenses for the perfection and the
continuation of the perfection of ▇▇▇▇▇▇'s security interest in the
Collateral. Grantor promptly will notify Lender before any change in
Grantor's name including any change to the assumed business names of
Grantor. This is a continuing Security Agreement and will continue in
effect even though all or any part of the indebtedness is paid in full and
even though for a period of time Grantor may not be indebted to Lender.

No Violation. The execution and delivery of this Agreement will not violate
any law or agreement governing Grantor or to which Grantor is a party, and
its certificate or articles of incorporation and bylaws do not prohibit any
term or condition of this Agreement.

Enforceability of Collateral. To the extent the Collateral consists of
accounts, chattel paper, or general intangibles, the Collateral is
enforceable in accordance with its terms, is genuine, and complies with
applicable laws concerning form, content and manner of preparation and
execution, and all persons appearing to be obligated on the Collateral have
authority and capacity to contract and are in fact obligated as they appear
to be on the Collateral. At the time any account becomes subject to a
security interest in favor of ▇▇▇▇▇▇, the account shall be a good and valid
account representing an undisputed, bona fide indebtedness incurred by the
account debtor, for merchandise held subject to delivery instructions or
theretofore shipped or delivered pursuant to a contract of sale, or for
services theretofore performed by Grantor with or for the account debtor;
there shall be no setoffs or counterclaims against any such account; and no
agreement under which any deductions or discounts may be claimed shall have
been made with the account debtor except those disclosed to Lender in
writing.

Location of the Collateral. Grantor, upon request of ▇▇▇▇▇▇, will deliver
to Lender in form satisfactory to Lender a schedule of real properties and
Collateral locations relating to Grantor's operations, including without
limitation the following: (a) all real property owned or being purchased by
Grantor; (b) all real property being rented or leased by Grantor; (c) all
storage facilities owned, rented,

leased, or being used by Grantor; and (d) all other properties where
Collateral is or may be located. Except in the ordinary course of its
business, Grantor shall not remove the Collateral from its existing
locations without the prior written consent of Lender.

Removal of Collateral. Grantor shall keep the Collateral (or to the extent
the Collateral consists of intangible property such as accounts, the
records concerning the Collateral) at Grantor's address shown above, or at
such other locations as are acceptable to Lender. Except in the ordinary
course of its business, including the sales of inventory, Grantor shall not
remove the Collateral from its existing locations without the prior written
consent of Lender. To the extent that the Collateral consists of vehicles,
or other titled property, Grantor shall not take or permit any action which
would require application for certificates of title for the vehicles
outside the State of Minnesota, without the prior written consent of
Lender.

Transactions Involving Collateral. Except for inventory sold or accounts
cancelled in the ordinary course of Grantor's business, Grantor shall not
sell, offer to sell, or otherwise transfer or dispose of the Collateral.
While Grantor is not in default under this Agreement, Grantor may sell
inventory, but only in the ordinary course of its business and only to
buyers who qualify as a buyer in the ordinary course of business. A sale in
the ordinary course of ▇▇▇▇▇▇▇'s business does not include a transfer in
partial or total satisfaction of a debt or any bulk sale. Grantor shall not
pledge, mortgage, encumber or otherwise permit the Collateral to be subject
to any lien, security interest, encumbrance, or charge, other than the
security interest provided for in this Agreement, without the prior written
consent of Lender. This includes security interests even if junior in right
to the security interests granted under this Agreement. Unless waived by
▇▇▇▇▇▇, all proceeds from any disposition of the Collateral (for whatever
reason) shall be held in trust for Lender and shall not be commingled with
any other funds; provided, however, this requirement shall not constitute
consent by Lender to any sale or other disposition. Upon receipt, Grantor
shall immediately deliver any such proceeds to Lender.

Title. Grantor represents and warrants to Lender that it holds good and
marketable title to the Collateral, free and clear of all liens and
encumbrances except for the lien of this Agreement. No financing statement
covering any of the Collateral is on file in any public office other than
those which reflect the security interest created by this Agreement or to
which Lender has specifically consented. Grantor shall defend ▇▇▇▇▇▇'s
rights in the Collateral against the claims and demands of all other
persons.

Collateral Schedules and Locations. As often as Lender shall require, and
insofar as the Collateral consists of accounts and general intangibles, Grantor
shall deliver to Lender schedules of such Collateral, including such information
as Lender may require, including without limitation names and addresses of
account debtors and agings of accounts and general intangibles. Insofar as the
Collateral consists of inventory and equipment, Grantor shall deliver to Lender,
as often as Lender shall require, such lists, descriptions, and designations of
such Collateral as Lender may require to identify the nature, extent, and
location of such

Collateral. Such information shall be submitted for Grantor and each of its
subsidiaries or related companies.

Maintenance and Inspection of Collateral. Grantor shall maintain all
tangible Collateral in good condition and repair. Grantor will not commit
or permit damage to or destruction of the Collateral or any part of the
Collateral. Lender and its designated representatives and agents shall have
the right at all reasonable times to examine, inspect, and audit the
Collateral wherever located. Grantor shall immediately notify Lender of all
cases involving the return, rejection, repossession, loss or damage of or
to any Collateral; of any request for credit or adjustment or of any other
dispute arising with respect to the Collateral; and generally of all
happenings and events affecting the Collateral or the value or the amount
of the Collateral.

Taxes, Assessments and Liens. Grantor will pay when due all taxes,
assessments and liens upon the Collateral, its use or operation, upon this
Agreement, upon any promissory note or notes evidencing the Indebtedness,
or upon any of the other Related Documents. Grantor may withhold any such
payment or may elect to contest any lien if Grantor is in good faith
conducting an appropriate proceeding to contest the obligation to pay and
so long as ▇▇▇▇▇▇'s interest in the Collateral is not jeopardized in
▇▇▇▇▇▇'s sole opinion. If the Collateral is subjected to a lien which is
not discharged within fifteen (15) days, Grantor shall deposit with Lender
cash, a sufficient corporate surety bond or other security satisfactory to
Lender in an amount adequate to provide for the discharge of the lien plus
any interest, costs, attorneys' fees or other charges that could accrue as
a result o foreclosure or sale of the Collateral. In any contest Grantor
shall defend itself and ▇▇▇▇▇▇ and shall satisfy any final adverse judgment
before enforcement against the Collateral. Grantor shall name ▇▇▇▇▇▇ as an
additional obligee under any surety bond furnished in the contest
proceedings.

Compliance with Governmental Requirements. Grantor shall comply promptly
with all laws, ordinances, rules and regulations of all governmental
authorities, now or hereafter in effect, applicable to the ownership,
production, disposition, or use of the Collateral. Grantor may contest in
good faith any such law, ordinance or regulation and withhold compliance
during any proceeding, including appropriate appeals, so long as ▇▇▇▇▇▇'s
interest in the Collateral, in ▇▇▇▇▇▇'s opinion, is not jeopardized.

Hazardous Substances. Grantor represents and warrants that the Collateral
never has been, and never will be so long as this Agreement remains a lien
on the Collateral, used for the generation, manufacture, storage,
transportation, treatment, disposal, release or threatened release of any
hazardous waste or substance, as those terms are defined in the
Comprehensive Environmental Response, Compensation, and Liability Act of
1980, as amended, 42 U.S.C. Section 9601, et seq. ("CERCLA"), the Superfund
Amendments and Reauthorization Act of 1986, Pub. L. No. 99-499 ("▇▇▇▇"),
the Hazardous Materials Transportation Act, 49 U.S.C. Section 1801, et
seq., the Resource Conservation and Recovery Act, 42 U.S.C. Section 6901,
et seq., or other applicable state or Federal laws, rules, or regulations
adopted pursuant to any of the foregoing. The terms "hazardous waste" and
"hazardous substance" shall also

include, without limitation, petroleum and petroleum by-products or any
fraction thereof and asbestos. The representations and warranties contained
herein are based on Grantor's due diligence in investigating the Collateral
for hazardous wastes and substances. Grantor hereby (a) releases and waives
any future claims against ▇▇▇▇▇▇ for indemnity or contribution in the event
Grantor becomes liable for cleanup or other costs under any such laws, and
(b) agrees to indemnify and hold harmless Lender against any and all claims
and losses resulting from a breach of this provision of this Agreement.
This obligation to indemnify shall survive the payment of the indebtedness
and the satisfaction of this Agreement.

Maintenance of Casualty Insurance. Grantor shall procure and maintain all
risks insurance, including without limitation fire, theft and liability
coverage together with such other insurance as Lender may require with
respect to the Collateral, in form, amounts, coverages and basis reasonably
acceptable to Lender and issued by a company or companies reasonably
acceptable to Lender. Grantor, upon request of ▇▇▇▇▇▇, will deliver to
Lender from time to time the policies or certificates of insurance in form
satisfactory to Lender, including stipulations that coverages will not be
cancelled or diminished without at least ten (10) days' prior written
notice to Lender and not including any disclaimer of the insurer's
liability for failure to give such a notice. Each insurance policy also
shall include an endorsement providing that coverage in favor of Lender
will not be impaired in any way by any act, omission or default of Grantor
or any other person. In connection with all policies covering assets in
which Lender holds or is offered a security interest, Grantor will provide
Lender with such loss payable or other endorsements as Lender may require.
If Grantor at any time fails to obtain or maintain any insurance as
required under this Agreement, Lender may (but shall not be obligated to)
obtain such insurance as Lender deems appropriate, including if it so
chooses "single interest insurance," which will cover only ▇▇▇▇▇▇'s
interest in the Collateral.

Application of Insurance Proceeds. Grantor shall promptly notify Lender of
any loss or damage to the Collateral. Lender may make proof of loss if
Grantor fails to do so within fifteen (15) days of the casualty. All
proceeds of any insurance on the Collateral, including accrued proceeds
thereon, shall beheld by Lender as part of the Collateral. If Lender
consents to repair or replacement of the damaged or destroyed Collateral,
Lender shall, upon satisfactory proof of expenditure, pay or reimburse
Grantor from the proceeds for the reasonable cost of repair or restoration.
If Lender does not consent to repair or replacement of the Collateral,
Lender shall retain a sufficient amount of the proceeds to pay all of the
indebtedness, and shall pay the balance to Grantor. Any proceeds which have
not been disbursed within six (6) months after their receipt and which
Grantor has not committed to the repair or restoration of the Collateral
shall be used to prepay the Indebtedness.

Insurance Reserves. Lender may require Grantor to maintain with Lender
reserves for payment of insurance premiums, which reserves shall be created
by monthly payments from Grantor of a sum estimated by Lender to be
sufficient to produce, at least fifteen (15) days before the premium due
date, amounts at least equal to the insurance premiums to be paid. If
fifteen (15) days before payment is due, the reserve funds are
insufficient, Grantor shall upon demand pay any

deficiency to Lender. The reserve funds shall be held by Lender as a
general deposit and shall constitute a non-interest-bearing account which
Lender may satisfy by payment of the insurance premiums required to be paid
by Grantor as they become due. Lender does not hold the reserve funds in
trust for Grantor, and ▇▇▇▇▇▇ is not the agent of Grantor for payment of
the insurance premiums required to be paid by Grantor. The responsibility
for the payment of premiums shall remain Grantor's sole responsibility.

Insurance Reports. Grantor, upon request of ▇▇▇▇▇▇, shall furnish to Lender
reports on each existing policy of insurance showing such information as
Lender may reasonably request including the following: (a) the name of the
insurer; (b) the risks insured; (c) the amount of the policy; (d) the
property insured; (e) the then current value on the basis of which
insurance has been obtained and the manner of determining that value; and
(f) the expiration date of the policy. In addition, Grantor shall upon
request by Lender (however not more often than annually) have an
independent appraiser satisfactory to Lender determine, as applicable, the
cash value or replacement cost of the Collateral.

▇▇▇▇▇▇▇'S RIGHT TO POSSESSION AND TO COLLECT ACCOUNTS. Until default and except
as otherwise provided below with respect to accounts, Grantor may have
possession of the tangible personal property and beneficial use of all the
Collateral and may use it in any lawful manner not inconsistent with this
Agreement or the Related Documents, provided that Grantor's right to possession
and beneficial use shall not apply to any Collateral where possession of the
Collateral by Lender is required by law to perfect Lender's security interest in
such Collateral. Until otherwise notified by ▇▇▇▇▇▇, Grantor may collect any of
the Collateral consisting of accounts. At any time and even though no Event of
Default exists, Lender may exercise its rights to collect the accounts and to
notify account debtors to make payments directly to Lender for application to
the Indebtedness. If Lender at any time has possession of any Collateral,
whether before or after an Event of Default, Lender shall be deemed to have
exercised reasonable care in the custody and preservation of the Collateral if
Lender takes such action for that purpose as Grantor shall request or as Lender,
in ▇▇▇▇▇▇'s sole discretion, shall deem appropriate under the circumstances, but
failure to honor any request by Grantor shall not of itself be deemed to be a
failure to exercise reasonable care. Lender shall not be required to take any
steps necessary to preserve any rights in the Collateral against prior parties,
nor to protect, preserve or maintain any security interest given to secure the
Indebtedness.

EXPENDITURES BY ▇▇▇▇▇▇. If not discharged or paid when due, Lender may (but
shall not be obligated to) discharge or pay any amounts required to be
discharged or paid by Grantor under this Agreement, including without limitation
all taxes, liens, security interests, encumbrances, and other claims, at any
time levied or placed on the Collateral. Lender also may (but shall not be
obligated to) pay all costs for insuring, maintaining and preserving the
Collateral. All such expenditures incurred or paid by Lender for such purposes
will then bear interest at the rate charged under the Note from the date
incurred or paid by Lender to the date of repayment by Grantor. All such
expenses shall become a part o the Indebtedness and, at ▇▇▇▇▇▇'s option, will
(a) be payable on demand, (b) be added to the balance of the Note and be
apportioned among and be payable with any installment payments to become due
during either (i) the term of any applicable insurance policy or (ii) the
remaining term of the Note, or (c) be treated as a balloon payment which will be
due and payable at the Note's maturity. This Agreement also will secure payment

of these amounts. Such right shall be in addition to all other rights and
remedies to which ▇▇▇▇▇▇ may be entitled upon the occurrence of an Event of
Default.

EVENTS OF DEFAULT. Each of the following shall constitute an Event of Default
under this Agreement:

Default on Indebtedness. Failure of Grantor to make any payment when due on
the Indebtedness.

Other Defaults. Failure of Grantor to comply with or to perform any other
term, obligation, covenant or condition contained in this Agreement or in
any of the Related Documents or in any other agreement between Lender and
Grantor.

Default in Favor of Third Parties. Should Borrower or any Grantor default
under any loan, extension of credit, security agreement, purchase or sales
agreement, or any other agreement, in favor of any other creditor or person
that may materially affect any of Borrower's property or Borrower's or any
Grantor's ability to repay the Loans or perform their respective
obligations under this Agreement or any of the Related Documents.

False Statements. Any warranty, representation or statement made or
furnished to Lender by or on behalf of Grantor under this Agreement, the
Note or the Related Documents is false or misleading in any material
respect, either now or at the time made or furnished.

Defective Collateralization. This Agreement or any of the Related Documents
ceases to be in full force and effect (including failure of any collateral
documents to crate a valid and perfected security interest or lien) at any
time and for any reason.

Insolvency. The dissolution or termination of ▇▇▇▇▇▇▇'s existence as a
going business, the insolvency of Grantor, the appointment of a receiver
for any part of Grantor's property, any assignment for the benefit of
creditors, any type of creditor workout, or the commencement of any
proceeding under any bankruptcy or insolvency laws by or against Grantor.

Creditor or Forfeiture Proceedings. Commencement of foreclosure or
forfeiture proceedings, whether by judicial proceeding, self-help,
repossession or any other method, by any creditor of Grantor or by any
governmental agency against the Collateral or any other collateral securing
the Indebtedness. This includes a garnishment of any of Grantor's deposit
accounts with ▇▇▇▇▇▇. However, this Event of Default shall not apply i
there is a good faith dispute by Grantor as to the validity or
reasonableness of the claim which is the basis of the creditor or
forfeiture proceeding and if Grantor gives ▇▇▇▇▇▇ written notice of the
creditor or forfeiture proceeding and deposits with Lender monies or a
surety bond for the creditor or forfeiture proceeding, in an amount
determined b Lender, in its sole discretion, as being an adequate reserve
or bond for the dispute.

Events Affecting Guarantor. Any of the preceding events occurs with respect
to any Guarantor of any of the Indebtedness or such Guarantor dies or
becomes

incompetent. Lender, at its option, may, but shall not be required to,
permit the Guarantor's estate to assume unconditionally the obligations
arising under the guaranty in a manner satisfactory to Lender, and, in
doing so, cure the Event of Default.

Adverse Change. A material adverse change occurs in Grantor's financial
condition, or ▇▇▇▇▇▇ believes the prospect of payment or performance of the
Indebtedness is impaired.

Insecurity. Lender, in good faith, deems itself insecure.

Right to Cure. If any default, other than a Default on Indebtedness, is
curable and if Grantor has not been given a prior notice of a breach of the
same provision of this Agreement, it may be cured (and no Event of Default
will have occurred) if Grantor, after ▇▇▇▇▇▇ sends written notice demanding
cure of such default (a) cures the default within fifteen (15) days; or
(b), if the cure requires more than fifteen (15) days, immediately
initiates steps which Lender deems in ▇▇▇▇▇▇'s sole discretion to be
sufficient to cure the default and thereafter continues and completes all
reasonable and necessary steps sufficient to produce compliance as soon as
reasonably practical.

RIGHTS AND REMEDIES ON DEFAULT. If an Event of Default occurs under this
Agreement, at any time thereafter, Lender shall have all the rights of a secured
party under the Minnesota Uniform Commercial Code. In addition and without
limitation, Lender may exercise any one or more of the following rights and
remedies:

Accelerate Indebtedness. ▇▇▇▇▇▇ may declare the entire Indebtedness,
including any prepayment penalty which Grantor would be required to pay,
immediately due and payable, without notice.

Assemble Collateral. Lender may require Grantor to deliver to Lender all or
any portion of the Collateral and any and all certificates of title and
other documents relating to the Collateral. Lender may require Grantor to
assemble the Collateral and make it available to Lender at a place to be
designated by Lender. ▇▇▇▇▇▇ also shall have full power to enter upon the
property of Grantor to take possession of and remove the Collateral. If the
Collateral contains other goods not covered by this Agreement at the time
of repossession, Grantor agrees Lender may take such other goods, provided
that ▇▇▇▇▇▇ makes reasonable efforts to return them to Grantor after
repossession.

Sell the Collateral. Lender shall have full power to sell, lease, transfer,
or otherwise deal with the Collateral or proceeds thereof in its own name
or that of Grantor. Lender may sell the Collateral at public auction or
private sale. Unless the Collateral threatens to decline speedily in value
or is of a type customarily sold on a recognized market, Lender will give
Grantor reasonable notice of the time after which any private sale or any
other intended disposition of the Collateral is to be made. The
requirements of reasonable notice shall be met if such notice is given at
least ten (10) days before the time of the sale or disposition. All
expenses relating to the disposition of the Collateral, including without
limitation the expenses of retaking, holding, insuring, preparing for sale
and selling the

Collateral, shall become a part of the Indebtedness secured by this
Agreement and shall be payable on demand, with interest at the Note rate
from date of expenditure until repaid.

Appoint Receiver. To the extent permitted by applicable law, ▇▇▇▇▇▇ shall
have the following rights and remedies regarding the appointment of a
receiver: (a) Lender may have a receiver appointed as a matter of right,
(b) the receiver may be an employee of ▇▇▇▇▇▇ and may serve without bond,
and (c) all fees of the receiver and his or her attorney shall become part
o the Indebtedness secured by this Agreement and shall be payable on
demand, with interest at the Note rate from date of expenditure until
repaid.

Collect Revenues, Apply Accounts. Lender, either itself or through a
receiver, may collect the payments, rents, income, and revenues from the
Collateral. Lender may at any time in its discretion transfer any
Collateral into its own name or that of its nominee and receive the
payments, rents, income, and revenues therefrom and hold the same as
security for the Indebtedness or apply it to payment of the Indebtedness in
such order of preference as Lender may determine. Insofar as the Collateral
consists of accounts, general intangibles, insurance policies, instruments,
chattel paper, chooses in action, or similar property, Lender may demand,
collect, receipt for, settle, compromise, adjust, sue for, foreclose, or
realize on the Collateral as Lender may determine, whether or not
Indebtedness or Collateral is then due. For these purposes, ▇▇▇▇▇▇ may, on
behalf of and in the name of Grantor, receive, open and dispose of mail
addressed to Grantor; change any address to which mail and payments are to
be sent; and endorse notes, checks, drafts, money orders, documents of
title, instruments and items pertaining to payment, shipment, or storage of
any Collateral. To facilitate collection, ▇▇▇▇▇▇ may notify account debtors
and obligors on any Collateral to make payments directly to Lender.

Obtain Deficiency. If ▇▇▇▇▇▇ chooses to sell any or all of the Collateral,
Lender may obtain a judgment against Grantor for any deficiency remaining
on the Indebtedness due to Lender after application of all amounts received
from the exercise of the rights provided in this Agreement. Grantor shall
be liable for a deficiency even if the transaction described in this
subsection is a sale of accounts or chattel paper.

Other Rights and Remedies. Lender shall have all the rights and remedies of
a secured creditor under the provisions of the Uniform Commercial Code, as
may be amended from time to time. In addition, Lender shall have and may
exercise any or all other rights and remedies it may have available at law,
in equity, or otherwise.

Cumulative Remedies. All of ▇▇▇▇▇▇'s rights and remedies, whether evidenced
by this Agreement or the Related Documents or by any other writing, shall
be cumulative and may be exercised singularly or concurrently. Election by
▇▇▇▇▇▇ to pursue any remedy shall not exclude pursuit of any other remedy,
and an election to make expenditures or to take action to perform an
obligation of Grantor under this Agreement, after ▇▇▇▇▇▇▇'s failure to
perform, shall not affect ▇▇▇▇▇▇'s right to declare a default and to
exercise its remedies.

this Agreement:

a lawsuit, including attorneys' fees and legal expenses for bankruptcy
proceedings (and including efforts to modify or vacate any automatic stay
or injunction), appeals, and any anticipated postjudgment collection

this Agreement by giving formal written notice to the other parties,
specifying that the purpose of the notice is to change the party's address.

payment for the Collateral; (c) to settle or compromise any and all claims
arising under the Collateral, and, in the place and stead of Grantor, to

file any claim or claims or to take any action or institute or take part in
any proceedings, either in its own name or in the name of the Grantor, or
otherwise, which in the discretion of Lender may seem to be necessary or
advisable. This power is given as security for the Indebtedness, and the
authority hereby conferred is and shall be irrevocable and shall remain in
full force and effect until renounced by ▇▇▇▇▇▇.

circumstance, such finding shall not render that provision invalid or
unenforceable as to any other persons or circumstances. If feasible, any

benefit of the parties, their successors and assigns.

Waiver. Lender shall not be deemed to have waived any rights under this
Agreement unless such waiver is given in writing and signed by ▇▇▇▇▇▇. No
delay or omission on the part of Lender in exercising any right shall
operate as a waiver of such right or any other right. A waiver by ▇▇▇▇▇▇ of
a provision of this Agreement shall not prejudice or constitute a waiver of
Lender's right otherwise to demand strict compliance with that provision or
any other provision of this Agreement. No prior waiver by ▇▇▇▇▇▇, nor any
course of dealing between ▇▇▇▇▇▇ and Grantor, shall constitute a waiver of
any of Lender's rights or of any of Grantor's obligations as to any future
transactions. Whenever the consent of Lender is required under this
Agreement, the granting of such consent by Lender in any instance shall not
constitute continuing consent to subsequent instances where such consent is
required and in all cases such consent may be granted or withheld in the
sole discretion of Lender.

Principal Amount: $1,250,000.00 Initial Rate: 10.250% Date of Note: July 17, 1996

================================================================================

PROMISE TO PAY. Delta Parts, Inc. ("Borrower") promises to pay to Century Bank
National Association ("Lender"), or order, in lawful money of the United States
of America, the principal amount of One Million Two Hundred Fifty Thousand &
00/100 Dollars ($1,250,000.00) or so much as may be outstanding, together with
interest on the unpaid outstanding principal balance of each advance. Interest
shall be calculated from the date of each advance until repayment of each
advance.

PAYMENT. Borrower will pay this loan in one payment of all outstanding principal
plus all accrued unpaid interest on June 30, 1997. In addition, ▇▇▇▇▇▇▇▇ will
pay regular monthly payments of accrued unpaid interest beginning August 1,
1996, and all subsequent interest payments are due on the same day of each month
after that. Interest on this Note is computed on a 365/360 simple interest
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. Borrower will pay
Lender at ▇▇▇▇▇▇'s address shown above or at such other place as Lender may
designate in writing. Unless otherwise agreed or required by applicable law,
payments will be applied first to any unpaid collection costs and any late
charges, then to any unpaid interest, and any remaining amount to principal.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from
time to time based on changes in an independent index which is the FIRST BANK
NATIONAL ASSOCIATION REFERENCE RATE (the "Index"). The Index is not necessarily
the lowest rate charged by Lender on its loans. If the Index becomes unavailable
during the term of this loan, Lender may designate a substitute index after
notice to Borrower. Lender will tell Borrower the current Index rate upon
▇▇▇▇▇▇▇▇'s request. Borrower understands that Lender may make loans based on
other rates as well. The interest rate change will not occur more often than
each Day. The Index currently is 8.250% per annum. The interest rate to be
applied to the unpaid principal balance of this Note will be at a rate of 2.000
percentage points over the Index, resulting in an initial rate of 10.250% per
annum. NOTICE: Under no circumstances will the interest rate on this Note be
more than the maximum rate allowed by applicable law.

PREPAYMENT. Borrower may pay without penalty all or a portion of the amount owed
earlier than it is due. Early payments will not, unless agreed to by ▇▇▇▇▇▇ in
writing, relieve ▇▇▇▇▇▇▇▇ of ▇▇▇▇▇▇▇▇'s obligation to continue to make payment
of accrued unpaid interest. Rather, they will reduce the principal balance due.

LATE CHARGE. If a payment is 11 days or more late, Borrower will be charged
5.000% of the regularly scheduled payment.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this Note or
any agreement related to this Note, or in any other agreement or loan Borrower
has with Lender. (c) Borrower defaults under any loan, extension of credit,
security agreement, purchase or sales agreement, or any other agreement, in
favor of any other creditor or person that may materially affect any of
Borrower's property or Borrower's ability to repay this Note or perform
Borrower's obligations under this Note or any of the Related Documents. (d) Any
representation or statement made or furnished to Lender by Borrower or on
▇▇▇▇▇▇▇▇'s behalf is false or misleading in any material respect either now or
at the time made or furnished. (e) ▇▇▇▇▇▇▇▇ becomes insolvent, a receiver is
appointed for any part of ▇▇▇▇▇▇▇▇'s property, ▇▇▇▇▇▇▇▇ makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor tries
to take any of ▇▇▇▇▇▇▇▇'s property on or in which ▇▇▇▇▇▇ has a lien or security
interest. This includes a garnishment of any of ▇▇▇▇▇▇▇▇'s accounts with ▇▇▇▇▇▇.
(g) Any guarantor dies or any of the other events described in this default
section occurs with respect to any guarantor of this Note. (h) A material
adverse change occurs in Borrower's financial condition, or ▇▇▇▇▇▇ believes the
prospect of payment or performance of the Indebtedness is impaired. (i) Lender
in good ▇▇▇▇▇ ▇▇▇▇▇ itself insecure.

If any default, other than a default in payment, is curable and if Borrower has
not been given a notice of a breach of the same provision of this Note within
the preceding twelve (12) months, it may be cured (and no event of default will
have occurred) if Borrower, after receiving written notice from Lender demanding
cure of such default: (a) cures the default within fifteen (15) days; or (b) if
the cure requires more than fifteen (15) days, immediately initiates steps which
Lender deems in ▇▇▇▇▇▇'s sole discretion to be sufficient to cure the default
and thereafter continues and completes all reasonable and necessary steps
sufficient to produce compliance as soon as reasonably practical.

LENDER'S RIGHTS. Upon default, ▇▇▇▇▇▇ may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest immediately due, without
notice, and then Borrower will pay that amount. Upon default, including failure
to pay upon final maturity, Lender, at its option, may also, if permitted under
applicable law, increase the variable interest rate on this Note to 6.000
percentage points over the Index. The interest rate will not exceed the maximum
rate permitted by applicable law. Lender may hire or pay someone else to help
collect this Note if Borrower does not pay. ▇▇▇▇▇▇▇▇ also will pay Lender that
amount. This includes, subject to any limits under applicable law, ▇▇▇▇▇▇'s
attorneys' fees and ▇▇▇▇▇▇'s legal expenses whether or not there is a lawsuit,
including attorneys' fees and legal expenses for bankruptcy proceedings
(including efforts to modify or vacate any automatic stay or injunction),
appeals, and any anticipated post-judgment collection services. If not
prohibited by applicable law, ▇▇▇▇▇▇▇▇ also will pay any court costs, in
addition to all other sums provided by law. This Note has been delivered to
Lender and accepted by ▇▇▇▇▇▇ in the State of Minnesota. If there is a lawsuit,
▇▇▇▇▇▇▇▇ agrees upon ▇▇▇▇▇▇'s request to submit to the jurisdiction of the
courts of Hennepin County, the State of Minnesota. This Note shall be governed
by and construed in accordance with the laws of the State of Minnesota.

DISHONORED ITEM FEE. Borrower will pay a fee to Lender of $21.00 if Borrower
makes a payment on Borrower's loan and the check or preauthorized charge with
which Borrower pays is later dishonored.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, ▇▇▇▇▇▇▇▇'s accounts
with Lender (whether checking, savings, or some other account), including
without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA and ▇▇▇▇▇ accounts,
and all trust accounts for which the grant of a security interest would be
prohibited by law. Borrower authorizes ▇▇▇▇▇▇, to the extent permitted by
applicable law, to charge or setoff all sums owing on this Note against any and
all such accounts.

LINE OF CREDIT. This Note evidences a revolving line of credit. Advances under
this Note, as well as directions for payment from ▇▇▇▇▇▇▇▇'s accounts, may be
requested orally or in writing by Borrower or by an authorized person. Lender
may, but need not, require that all oral requests be confirmed in writing. The
following party or parties are authorized to request advances under the line of
credit until ▇▇▇▇▇▇ receives from Borrower at ▇▇▇▇▇▇'s address shown above
written notice of revocation of their authority: ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, President;
▇▇▇▇ ▇. ▇▇▇▇▇, Chief Operating Officer; and ▇▇▇ ▇▇▇▇, Controller. ▇▇▇▇▇▇▇▇
agrees to be liable for all sums either: (a) advanced in accordance with the
instructions of an authorized person or (b) credited to any of ▇▇▇▇▇▇▇▇'s
accounts with ▇▇▇▇▇▇. The unpaid principal balance owing on this Note at any
time may be evidenced by endorsements on this Note or by ▇▇▇▇▇▇'s internal
records, including daily computer print-outs. Lender will have no obligation to
advance funds under this Note if: (a) Borrower or any guarantor is in default
under the terms of this Note or any agreement that Borrower or any guarantor has
with Lender, including any agreement made in connection with the signing of this
Note; (b) Borrower or any guarantor ceases doing business or is insolvent; (c)
any guarantor seeks, claims or otherwise attempts to limit, modify or revoke
such guarantor's guarantee of this Note or any other loan with Lender; (d)
Borrower has applied funds provided pursuant to this Note for purposes other
than those authorized by Lender; or (e) Lender in good ▇▇▇▇▇ ▇▇▇▇▇ itself
insecure under this Note or any other agreement between Lender and Borrower.

PROVISION FOR THE TIMELY RECEIPT OF FINANCIAL STATEMENTS. The receipt of timely
financial statements as required hereunder or under the Loan Agreement is an
event of default. The applicable interest rate to the loan, for a period
beginning fifteen (15) days after written notice of such default and ending upon
the curing of said noticed default, shall increase one percent (1.0%) for the
first thirty (30) days of said default and increase an additional one percent
(1.0%) during each thirty (30) days thereafter, during which the default
continues. Such default interest rates shall apply to the outstanding principal
balance of the loan. Upon the curing of the noticed default, the interest rate
on the loan shall revert back to the initially agreed-upon interest rate
effective on the date on which the default is cured. In the event that the
lender accelerates the loan as a result of such noticed default, the interest
rate on the loan shall revert to the initially agreed-upon interest rate in
effect on the date on which such acceleration is made.

GENERAL PROVISIONS. Lender may delay or forgo enforcing any of its rights or
remedies under this Note without losing them. Borrower and any other person who
signs, guarantees or endorses this Note, to the extent allowed by law, waive
presentment, demand for payment, protest and notice of dishonor. Upon any change
in the terms of this Note, and unless otherwise expressly stated in writing, no
party who signs this Note, whether as maker, guarantor, accommodation maker or
endorser, shall be released from liability. All such parties agree that Lender
may renew or extend (repeatedly and for any length of time) this loan, or
release any party or guarantor or collateral; or impair, fail to realize upon or
perfect ▇▇▇▇▇▇'s security interest in the collateral; and take any other action
deemed necessary by Lender without the consent of or

notice to anyone. All such parties also agree that ▇▇▇▇▇▇ may modify this loan
without the consent of or notice to anyone other than the party with whom the
modification is made.

PRIOR TO SIGNING THIS NOTE, ▇▇▇▇▇▇▇▇ READ AND UNDERSTOOD ALL THE PROVISIONS OF
THIS NOTE, INCLUDING THE VARIABLE INTEREST RATE PROVISIONS. ▇▇▇▇▇▇▇▇ AGREES TO

====================================================================================================

AMOUNT OF GUARANTY. The amount of this Guaranty is Unlimited.

CONTINUING UNLIMITED GUARANTY. For good and valuable consideration, ▇▇▇▇▇▇▇ ▇.
▇▇▇▇▇▇▇ ("Guarantor") absolutely and unconditionally guarantees and promises to
pay to Century Bank National Association ("Lender") or its order, in legal
tender of the United States of America, the indebtedness (as that term is
defined below) of Delta Parts, Inc. ("borrower") to Lender on the terms and
conditions set forth in this Guaranty. Under this Guaranty, the liability of
Guarantor is unlimited and the obligations of Guarantor are continuing.

DEFINITIONS: The following words shall have the following meanings when used in
this Guaranty:

Borrower. The word "borrower" means Delta Parts, Inc.

Guarantor. The word "Guarantor" means ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇.

Guaranty. The word "Guaranty" means that this Guaranty made by Guarantor
for the benefit of Lender dated July 17, 1996.

Indebtedness. The word "Indebtedness" is used in its most comprehensive
sense and means and includes any and all of Borrower's liabilities,
obligations, debts, and indebtedness to Lender, now existing or
hereinafter incurred or created, including, without limitation, all
loans, advances, interests, costs, debts, overdraft indebtedness, credit
card indebtedness, lease obligations, other obligations, and liabilities
of Borrower, or any of them, and any present or future judgments against
Borrower, or any of them; and whether any such indebtedness is
voluntarily or involuntarily incurred, due or not due, absolute or
contingent, liquidated, or unliquidated, determined or undetermined;
whether Borrower may be liable individually or jointly with others, or
primarily or secondarily, or as guarantor or surety; whether recovery on
the Indebtedness may be or may become barred or unenforceable against
Borrower for any reason whatsoever; and whether the Indebtedness arises
from transactions which may be voidable on account of infancy, insanity,
ultra ▇▇▇▇▇, or otherwise.

Lender. The word "Lender" means Century Bank National Association, its
successors and assigns.

Related Documents. The words "Related Documents" mean and include
without limitation all promissory notes, credit agreements, loan
agreements, environmental agreements, guaranties, security agreements,
mortgages, deeds of trust, and all other instruments, agreements and
documents, whether now or hereafter existing, executed in connection
with the Indebtedness.

NATURE OF GUARANTY. Guarantor's liability under this Guaranty shall be open and
continuous for so long as this Guaranty remains in force. Guarantor intends to
guarantee at all times the performance and prompt payment when due, whether at
maturity or earlier by reason of acceleration or otherwise, of all Indebtedness.
Accordingly, no payments made upon the Indebtedness will discharge or diminish
the continuing liability of Guarantor in connection with any remaining portions
of the Indebtedness or any of the Indebtedness which subsequently arises or is
thereafter incurred or contracted.

DURATION OF GUARANTY. This Guaranty will take effect when received by Lender
without the necessity of any acceptance by ▇▇▇▇▇▇, or any notice to Guarantor or
to Borrower, and will continue in full force until all Indebtedness incurred or
contracted before receipt by Lender of any notice of revocation shall have been
fully and finally paid and satisfied and all other obligations of Guarantor
under this Guaranty shall have been performed in full. If Guarantor elects to
revoke this Guaranty, Guarantor may only do so in writing. Guarantor's written
notice of revocation must be mailed to Lender, by certified mail, at the address
of Lender listed above or such other place as Lender may designate in writing.
Written revocation of this Guaranty will apply only to advances or new
Indebtedness created after actual receipt by lender of Guarantor's written
revocation. For this purpose and without limitation, the term "new Indebtedness"
does not include Indebtedness which at the time of notice of revocation is
contingent, unliquidated, undetermined or not due and which later becomes
absolute, liquidated, determined or due. This Guaranty will continue to bind
Guarantor for all Indebtedness incurred by Borrower or committed by Lender prior
to receipt of Guarantor's written notice of revocation, including any
extensions, renewals, substitutions or modifications of the Indebtedness. All
renewals, extensions, substitutions, and modifications of the Indebtedness
granted after Guarantor's revocation, are contemplated under this Guaranty and,
specifically will not be considered to be new Indebtedness. This Guaranty shall
bind the estate of Guarantor as to Indebtedness created both before and after
the death or incapacity of Guarantor, regardless of Lender's actual notice of
Guarantor's death. Subject to the foregoing, Guarantor's executor or
administrator or other legal representative may terminate this Guaranty in the
same manner in which Guarantor might have terminated it and with the same
effect. Release of any other guarantor or termination of any other guaranty of
the Indebtedness shall not affect the liability of Guarantor under this
Guaranty. A revocation received by Lender from any one or more Guarantors shall
not affect the liability of any remaining Guarantors under this Guaranty. It is
anticipated that fluctuations may occur in the aggregate amount of Indebtedness
covered by this Guaranty, and it is specifically acknowledged and agreed by
Guarantor that reductions in the amount of Indebtedness, even to zero dollars
($0.00), prior to written revocation of this Guaranty by Guarantor shall not
constitute a termination of this Guaranty. This Guaranty is binding upon
Guarantor and Guarantor's heirs, successors and assigns so long as any of the
guaranteed Indebtedness remains unpaid and even through the Indebtedness
guaranteed may from time to time be zero dollars ($0.00).

GUARANTOR'S AUTHORIZATION TO LENDER. Guarantor authorizes ▇▇▇▇▇▇, either before
or after any revocation hereof, without notice or demand and without lessening
Guarantor's liability under this Guaranty, from time to time: (a) prior to
revocation as set

forth above, to make one or more additional secured or unsecured loans to
Borrower, to lease equipment or other goods to Borrower, or otherwise to extend
additional credit to Borrower; (b) to alter, compromise, renew, extend,
accelerate, or otherwise change one or more times the time for payment or other
terms of the Indebtedness or any part of the Indebtedness, including increases
and decreases of the rate of interest on the Indebtedness; extensions may be
repeated and may be for longer than the original loan term; (c) to take and hold
security for the payment of this Guaranty or the Indebtedness, and exchange,
enforce, waive, subordinate, full or decide not to perfect, and release any such
security, with or without the substitution of new collateral; (d) to release,
substitute, agree not to use, or deal with any one or more of Borrower's
sureties, endorsers, or other guarantors on any terms or in any manner Lender
may choose; (3) to determine how, when and what application of payments and
credits shall be made on the Indebtedness; (f) to apply such security and direct
the order or manner of sale thereof, including without limitation, any
nonjudicial sale permitted by the terms of the controlling security agreement or
deed of trust, as Lender in its discretion may determine; (g) to sell, transfer,

any right to require Lender (a) to continue lending money or to extend other
credit to Borrower; (b) to make any presentment, protest, demand, or notice of
any kind, including notice of any nonpayment of the Indebtedness or of any

payment Guarantor may now have or hereafter have or acquire against Borrower, by
subrogation or otherwise, so that at no time shall Guarantor be or become a

thereafter ▇▇▇▇▇▇ is forced to remit the amount of that payment to ▇▇▇▇▇▇▇▇'s
trustee in bankruptcy or to any similar person under any federal or state
bankruptcy law or law for the relief of debtors, the Indebtedness shall be
considered unpaid for the purpose of enforcement of this Guaranty.

Guarantor further waives and agrees not to assert or claim at any time any
deductions to the amount guaranteed under this Guaranty for any claim of setoff,
counterclaim, counter demand, recoupment or similar right, whether such claim,
demand or right may be asserted by the Borrower, the Guarantor, or both.

GUARANTOR'S UNDERSTANDING WITH RESPECT TO WAIVERS. Guarantor
warrants and agrees that each of the waivers set forth above is made with
Guarantor's full knowledge of its significances and that, under the
circumstances, the waivers are reasonable and not contrary to public policy or
law. If any such waiver is determined to be contrary to any applicable law or
public policy, such waiver shall be effective only to the extent permitted by
law or public policy.

▇▇▇▇▇▇'S RIGHT OF SETOFF. In addition to all liens upon and rights of setoff
against the moneys, securities or other property of Guarantor given to Lender by
law, Lender shall have, with

respect to Guarantor's obligations to Lender under this Guaranty and to the
extent permitted by law, a contractual possessory security interest in and a
right of setoff against, and Guarantor hereby assigns, conveys, delivers,
pledges, and transfers to Lender all of Guarantor's right, title and interest in
and to, all deposits, moneys, securities and other property of Guarantor now or
hereafter in possession of or on deposit with Lender, whether held in a general
or special account or deposit, whether held jointly with someone else, or held
in safekeeping or otherwise, excluding however all IRA, ▇▇▇▇▇, and trust
accounts. Every such security interest and right of setoff may be exercised
without demand upon a notice to Guarantor. No security interest or right of
setoff shall be deemed to have been waived by any act or conduct on the part of
Lender or by any neglect to exercise such right of setoff or to enforce such
security interest or by any delay in so doing. Every right of setoff and
security interest shall continue in full force and effect until such right of
setoff or security interest is specifically waived or released by an instrument
in writing executed by ▇▇▇▇▇▇.

SUBORDINATION OF ▇▇▇▇▇▇▇▇'S DEBTS TO GUARANTOR. Guarantor agrees that
the Indebtedness of Borrower to Lender, whether now existing or hereafter
created, shall be prior to any claim that Guarantor may now have or hereafter
acquire against Borrower, whether or not Borrower becomes insolvent. Guarantor
hereby expressly subordinates any claim Guarantor may have against Borrower,
upon any account whatsoever, to any claim that Lender may now or hereafter have
against Borrower. In the event of insolvency and consequent liquidation of the
assets of Borrower, through bankruptcy, by an assignment or the benefit of
creditors, by voluntary liquidation, or otherwise, the assets of Borrower
applicable to the payment of the claims of both Lender and Guarantor shall be
paid to Lender and shall be first applied by Lender to the Indebtedness of
Borrower to Lender. Guarantor does hereby assign to Lender all claims which it
may have to acquire against Borrower or against any assignee or trustee in
bankruptcy of Borrower; provided however, that such assignment shall be
effective only for the purpose of assuring to Lender full payment in legal
tender of the Indebtedness. If Lender so requests, any notes or credit
agreements now or hereafter evidencing any debts or obligations of Borrower to
Guarantor shall be marked with a legend that the same are subject to this
Guaranty and shall be delivered to Lender. ▇▇▇▇▇▇▇▇▇ agrees, and ▇▇▇▇▇▇ hereby
is authorized, in the name of Guarantor, from time to time to execute and file
financing statements and continuation statements and to execute such other
documents and to take such other actions as Lender deems necessary or
appropriate to perfect, preserve and enforce its rights under this Guaranty.

overnight courier, or when deposited in the United States mail, first
class postage prepaid, addressed to the party to whom the notice is to

Guarantor shall be in writing and shall be effective only upon delivery

will constitute notice to all Guarantors. For notice purposes, ▇▇▇▇▇▇▇▇▇
agrees to keep ▇▇▇▇▇▇ informed at all times of Guarantor's current
address.

Interpretation. In all cases where there is more than one Borrower or
Guarantor, then all words used in this Guaranty in the singular shall be
deemed to have been used in the plural where the context and
construction so require; and where there is more than one Borrower named
in this Guaranty or when this Guaranty is executed by more than one
Guarantor, the words "Borrower" and "Guarantor" respectively shall mean
all and any one or more of them. The words "Guarantor," "Borrower," and
"Lender" include the heirs, successors, assigns, and transferees of each
of them. Caption headings in this Guaranty are for convenience purposes
only and are not to be used to interpret or defined the provisions of
this Guaranty. If a court of competent jurisdiction finds any provision
of this Guaranty to be invalid or unenforceable as to any person or
circumstance, such finding shall not render that provision invalid or
unenforceable as to any other persons or circumstances, and all
provision of this Guaranty in all other aspects shall remain valid and
enforceable. If any one or more of Borrower or Guarantor are
corporations or partnerships, it is not necessary for Lender to inquire

partners, or agents acting or purporting to act on their behalf, and any
indebtedness made or created in reliance upon the professed exercise of
such powers shall be guaranteed under this Guaranty.

Waiver. Lender shall not be deemed to have waived any rights under this
Guaranty unless such waiver is given in writing and signed by ▇▇▇▇▇▇. No
delay or omission on the part of Lender in exercising any right shall
operate as a waiver of such right or any other right. A waiver by ▇▇▇▇▇▇
of a provision of this Guaranty shall not prejudice or constitute a
waiver of Lender's right otherwise to demand strict compliance with that
provision or any other provision of this Guaranty. No prior waiver by
▇▇▇▇▇▇, nor any course of dealing between ▇▇▇▇▇▇ and Guarantor, shall
constitute a waiver of any of Lender's rights or of any of Guarantor's
obligations as to any future transactions. Whenever the content of
Lender is required under this Guaranty, the granting of such consent by
Lender in any instance shall not constitute continuing consent to
subsequent instances where such

consent is required and in all cases such consent may be granted or
withheld in the sole discretion of Lender.

AMOUNT OF GUARANTY. The amount of this Guaranty is Unlimited.

CONTINUING UNLIMITED GUARANTY. For good and valuable consideration, ▇▇▇▇ ▇.
▇▇▇▇▇ ("Guarantor") absolutely and unconditionally guarantees and promises to
pay to Century Bank National Association ("Lender") or its order, in legal
tender of the United States of America, the Indebtedness (as that term is
defined below) of Delta Parts, Inc. ("Borrower") to Lender on the terms and
conditions set forth in this Guaranty. Under this Guaranty, the liability of
Guarantor is unlimited and the obligations of Guarantor are continuing.

DEFINITIONS. The following words shall have the following meanings when used in
this Guaranty:

Borrower. The word "Borrower" means Delta Parts, Inc.

Guarantor. The word "Guarantor" means ▇▇▇▇ ▇. ▇▇▇▇▇.

Guaranty. The word "Guaranty" means this Guaranty made by Guarantor for
the benefit of ▇▇▇▇▇▇ dated July 17, 1996.

Indebtedness. The word "Indebtedness" is used in its most comprehensive
sense and means and includes any and all of Borrower's liabilities,
obligations, debts, and indebtedness to Lender, now existing or
hereinafter incurred or created, including, without limitation, all
loans, advances, interest, costs, debts, overdraft indebtedness, credit
card indebtedness, lease obligations, other obligations, and liabilities
of Borrower, or any of them, and any present or future judgments against
Borrower, or any of them; and whether any such Indebtedness is
voluntarily or involuntarily incurred, due or not due, absolute or
contingent, liquidated or unliquidated, determined o undetermined;
whether Borrower may be liable individual or jointly with others, or
primarily or secondarily, or as guarantor or surety; whether recovery on
the Indebtedness may be or may become barred or unenforceable against
Borrower for any reason whatsoever; and whether the Indebtedness arises
from transactions which may be voidable on account of infancy, insanity,
ultra ▇▇▇▇▇, or otherwise.

Lender. The word "Lender" means Century Bank National Association, its
successors and assigns.

Related Documents. The words "Related Documents" mean and include
without limitation all promissory notes, credit agreements, loan
agreements, environmental agreements, guaranties, security agreements,
mortgages, deeds of trust, and all other instruments, agreements and
documents, whether now or hereafter existing, executed in connection
with the indebtedness.

NATURE OF GUARANTY. Guarantor's liability under this Guaranty shall be open and
continuous for so long as this Guaranty remains in force. Guarantor intends to
guarantee at all times the performance and prompt payment when due, whether at
maturity or earlier by reason of acceleration or otherwise, of all indebtedness.
Accordingly, no payments made upon the indebtedness will discharge or diminish
the continuing liability of Guarantor in connection with any remaining portions
of the Indebtedness or any of the Indebtedness which subsequently arises or is
thereafter incurred or contracted.

DURATION OF GUARANTY. This Guaranty will take effect when received by Lender
without the necessity of any acceptance by Lender, or any notice to Guarantor or
to Borrower, and will continue in full force until all Indebtedness incurred or
contracted before receipt by Lender or any notice of revocation shall have been
fully and finally paid and satisfied and all other obligations o Guarantor under
this Guaranty shall have been performed in full. If Guarantor elects to revoke
this Guaranty, Guarantor may only do so in writing. Guarantor's written notice
of revocation must be mailed to Lender, by certified mail, at the address of
Lender listed above or such other place as Lender may designate in writing.
Written revocation of this Guaranty will apply only to advances or new
Indebtedness created after actual receipt by ▇▇▇▇▇▇ of Guarantor's written
revocation. For this purpose and without limitation, the term "new Indebtedness"
does not include Indebtedness which at the time of notice of revocation is
contingent, unliquidated, undetermined or not due and which later becomes
absolute, liquidated, determined or due. This Guaranty will continue to bind
Guarantor for all Indebtedness incurred by Borrower or committed by Lender prior
to receipt of Guarantor's written notice of revocation, including any
extensions, renewals, substitutions or modification of the Indebtedness. All
renewals, extensions, substitutions, and modifications of the Indebtedness
granted after Guarantor's revocation, are contemplated under this Guaranty and,
specifically will not be considered to be new Indebtedness. This Guaranty shall
bind the estate of Guarantor as to Indebtedness created both before and after
the death or incapacity of Guarantor, regardless of Lender's actual notice of
Guarantor's death. Subject to the foregoing, Guarantor's executor or
administrator or other legal representative may terminate this Guaranty in the
same manner in which Guarantor might have terminated it and with the same
effect. Release of any other guarantor or termination of any other guaranty of
the Indebtedness shall not affect the liability of Guarantor under this
Guaranty. A revocation received by Lender from any one or more Guarantors shall
not affect the liability of any remaining Guarantors under this Guaranty. It is
anticipated that fluctuations may occur in the aggregate amount of Indebtedness
covered by this Guaranty, and it is specifically acknowledged and agreed by
Guarantor that reductions in aggregate amount of Indebtedness covered by this
Guaranty, and it is specifically acknowledged and agreed by the Guarantor that
reductions in the amount of Indebtedness, even to zero dollars ($0.00), prior to
written revocation of this Guaranty by the Guarantor shall not constitute a
termination of this Guaranty. This Guaranty is binding upon Guarantor and
Guarantor's heirs, successors and assigns so long as any of the guaranteed
Indebtedness remains unpaid and even though the Indebtedness guaranteed may from
time to time be zero dollars ($0.00).

GUARANTOR'S AUTHORIZATION TO LENDER. Guarantor authorizes ▇▇▇▇▇▇, either before
or after any revocation hereof, without notice or demand and without lessening

Guarantor's liability under this Guaranty, from time to time: (a) prior to

loans to Borrower, to lease equipment or other goods to Borrower, or otherwise

action (including those for unpaid taxes) against Guarantor is pending or
threatened; (i) Lender has made no representation to Guarantor as to the

of obtaining from Borrower on a continuing basis information regarding

applicable provisions of the Uniform Commercial Code; (f) to pursue any other
remedy within Lender's power; or (g) to commit any act or omission of any kind,
or at any time, with respect to any matter whatsoever.

Guarantor also waives any and all rights or defenses arising by reason of (a)

Guarantor, before or after Lender's commencement or completion of any
foreclosure action, either judicially or by exercise of a power of sale; (b) any
election of remedies by Lender which destroys or otherwise adversely affects

Indebtedness; (c) any disability or other defense of Borrower or any other

created, shall be prior to any claim that Guarantor may now have or hereafter
acquire against Borrower, whether or not Borrower becomes insolvent. Guarantor

upon any account whatsoever, to any claim that Lender may now or hereafter have
against Borrower. In the event of insolvency and consequent liquidation of the
assets of Borrower, through bankruptcy, by an assignment for the benefit of
creditors, by voluntary liquidation, or otherwise, the assets of Borrower
applicable to the payment of the claims of both ▇▇▇▇▇▇ and Guarantor shall be
paid to Lender and shall be first applied by Lender to the Indebtedness of
Borrower to Lender. Guarantor does hereby assign to Lender all claims which it
may have or acquire against Borrower or against any assignee or trustee in
bankruptcy of Borrower; provided however, that such assignment shall be
effective only for the purposes of assuring to Lender full payment in legal
tender of the Indebtedness. If Lender so requests, any notes or credit
agreements now or hereafter evidencing any debts or obligations of Borrower to
Guarantor shall be marked with a legend that the same are subject to this
Guaranty and shall be delivered to Lender. ▇▇▇▇▇▇▇▇▇ agrees, and ▇▇▇▇▇▇ hereby
is authorized, in the name of Guarantor, from time to time to execute and file
financing statements and continuation statement and to execute such other

Lender is required under this Guaranty, the granting of such consent by
