</TABLE>

     PROMISE TO PAY. Pro Uro Care Inc. ("Borrower") promises to pay to Venture
     Bank ("Lender"), or order, In lawful money of the United States of America,
     the principal amount of One Hundred Thousand & 00/100 Dollars
     ($100,000.00), together with interest at the rate of 7.000% per annum on
     the unpaid principal balance from March 31, 2005, until paid In full.

     PAYMENT. Borrower will pay this loan In one principal payment of
     $100,000.00 plus Interest on July 2, 2005. This payment due on July 2,
     2005, will be for all principal and all accrued Interest not yet paid. In
     addition, Borrower will pay regular monthly payments of all accrued unpaid
     interest due as of each payment date, beginning May 2, 2005, with all
     subsequent interest payments to be due on the same day of each month after
     that. Unless otherwise agreed or required by applicable law, payments will
     be applied first to any accrued unpaid Interest; then to principal; then to
     any unpaid collection costs; and then to any late charges. The annual
     Interest rate for this Note is computed on a 365/360 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 Lender's address shown above or at such other place as Lender may
     designate in writing.

     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
     Lender in writing, relieve Borrower of Borrower's obligation to continue to
     make payments under the payment schedule. Rather, early payments will
     reduce the principal balance due. Borrower agrees not to send Lender
     payments marked "paid in full", "without recourse", or similar language. If
     Borrower sends such a payment, Lender may accept it without losing any of
     Lender's rights under this Note, and Borrower will remain obligated to pay
     any further amount owed to Lender. All written communications concerning
     disputed amounts, including any check or other payment instrument that
     indicates that the payment constitutes "payment in full" of the amount owed
     or that is tendered with other conditions or limitations or as full
     satisfaction of a disputed amount must be mailed or delivered to: Venture
     Bank, 5601 Green Valley Drive, Suite 120, Bloomington, MN 55437.

     LATE CHARGE. If a payment is 10 days or more late, Borrower will be charged
     5.000% of the unpaid portion of the regularly scheduled payment.

     INTEREST AFTER DEFAULT. Upon default, including failure to pay upon final
     maturity, Lender, at its option, may, if permitted under applicable law,
     increase the interest rate on this Note 2.000 percentage points. The
     interest rate will not exceed the maximum rate permitted by applicable law.

     DEFAULT. Each of the following shall constitute an event of default ("Event
     of Default") under this Note:

          Payment Default. Borrower fails to make any payment when due under
          this Note.

          Other Defaults. Borrower fails to comply with or to perform any other
          term, obligation, covenant or condition contained in this Note or in
          any of the related documents or to comply with or to perform any term,
          obligation, covenant or condition contained in any other agreement
          between Lender and Borrower.

          False Statements. Any warranty, representation or statement made or
          furnished to Lender by Borrower or on Borrower's behalf under this

          respect, either now or at the time made or furnished or becomes false
          or misleading at any time thereafter.

          Insolvency. The dissolution or termination of Borrower's existence as
          a going business, the insolvency of Borrower, the appointment of a
          receiver for any part of Borrower'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 Borrower.

          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 Borrower or by
          any governmental agency against any collateral securing the loan. This
          includes a garnishment of any of Borrower's accounts, including
          deposit accounts, with Lender. However, this Event of Default shall
          not apply if there is a good faith dispute by Borrower as to the
          validity or reasonableness of the claim which is the basis of the
          creditor or forfeiture proceeding and if Borrower gives Lender 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 by Lender, in its sole discretion,
          as being an adequate reserve or bond for the dispute.

          Note. In the event of a death, 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 any Event of Default.

          performance of this Note is impaired.

          Insecurity. Lender in good faith believes itself insecure.

          Cure Provisions. 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 if Borrower, after receiving written notice from
          Lender demanding cure of such default: (1) cures the default within
          fifteen (15) days; or (2) if the cure requires more than fifteen (15)
          days, immediately initiates steps which Lender deems in Lender'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, Lender may declare the entire unpaid
     principal balance on this Note and all accrued unpaid interest immediately
     due, and then Borrower will pay that amount.

or contingent, liquidated or unliquidated whether Grantor may be liable
individually or jointly with others, whether obligated as guarantor, surety,
accommodation party or otherwise, and whether recovery upon such amounts may be
or hereafter may become barred by any statute of limitations, and whether the
obligation to repay such amounts may be or hereafter may become otherwise
unenforceable.

RIGHT OF SETOFF. To the extent permitted by applicable law, Lender reserves a
right of setoff in all Grantor's accounts with Lender (whether checking,
savings, or some other account). This includes all accounts Grantor holds
jointly with someone else and all accounts Grantor may open in the future.
However, this does not include any IRA or Keogh accounts, or any trust accounts
for which setoff would be prohibited by law. Grantor authorizes Lender, to the
extent permitted by applicable law, to charge or setoff all sums owing on the
Indebtedness against any and all such accounts, and, at Lender's option, to
administratively freeze all such accounts to allow Lender to protect Lender's
charge and setoff rights provided in this paragraph.

GRANTOR'S REPRESENTATIONS AND WARRANTIES WITH RESPECT TO THE COLLATERAL. With
respect to the Collateral, Grantor represents and promises to Lender that:

          Perfection of Security Interest. Grantor agrees to take whatever
          actions are requested by Lender to perfect and continue Lender's
          security interest in the Collateral. Upon request of Lender, Grantor
          will deliver to Lender any and all of the documents evidencing or
          constituting the Collateral, and Grantor will note Lender's interest
          upon any and all chattel paper and instruments if not delivered to
          Lender for possession by Lender.

          Notices to Lender. Grantor will promptly notify Lender in writing at
          Lender's address shown above (or such other addresses as Lender may
          designate from time to time) prior to any (1) change in Grantor's
          name; (2) change in Grantor's assumed business name(s); (3) change in
          the management of the Corporation Grantor; (4) change in the

          address; (6) change in Grantor's state of organization; (7) conversion
          of Grantor to a new or different type of business entity; or (8)
          change in any other aspect of Grantor that directly or indirectly
          relates to any agreements between Grantor and Lender. No change in
          Grantor's name

                          COMMERCIAL SECURITY AGREEMENT
Loan No: 11325                     (Continued)                            Page 2

or state of organization will take effect until after Lender has received
notice.

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, as defined by the Uniform Commercial
Code, the Collateral is enforceable in accordance with its terms, is genuine,
and fully complies with all applicable laws and regulations 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 Lender, 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 previously shipped or delivered pursuant to a contract of sale,
or for services previously performed by Grantor with or for the account debtor.
So long as this Agreement remains in effect, Grantor shall not, without Lender's
prior written consent, compromise, settle, adjust, or extend payment under or
with regard to any such Accounts. There shall be no setoffs or counterclaims
against any of the Collateral, and no agreement shall have been made under which
any deductions or discounts may be claimed concerning the Collateral except
those disclosed to Lender in writing.

Location of the Collateral. Except in the ordinary course of Grantor's business,
Grantor agrees to keep the Collateral (or to the extent the Collateral consists
of intangible property such as accounts or general intangibles, the records
concerning the Collateral) at Grantor's address shown above or at such other
locations as are acceptable to Lender. Upon Lender's request, Grantor 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: (1) all real property Grantor owns or is purchasing;
(2) all real property Grantor is renting or leasing; (3) all storage facilities
Grantor owns, rents, leases, or uses; and (4) all other properties where
Collateral is or may be located.

Removal of the Collateral. Except in the ordinary course of Grantor's business,
including the sales of inventory, Grantor shall not remove the Collateral from
its existing location without Lender's prior written consent. 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 Lender's prior
written consent. Grantor shall, whenever requested, advise Lender of the exact
location of the Collateral.

Transactions Involving Collateral. Except for inventory sold or accounts
collected in the ordinary course of Grantor's business, or as otherwise provided
for in this Agreement, 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 Grantor'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 Lender,
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 Grantor 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 Lender's rights in the Collateral
against the claims and demands of all other persons.

Repairs and Maintenance. Grantor agrees to keep and maintain, and to cause
others to keep and maintain, the Collateral in good order, repair and condition
at all times while this Agreement remains in effect. Grantor further agrees to
pay when due all claims for work done on, or services rendered or material
furnished in connection with the Collateral so that no lien or encumbrance may
ever attach to or be filed against the Collateral.

Inspection of Collateral. Lender and Lender's designated representatives and
agents shall have the right at all reasonable times to examine and inspect the
Collateral wherever located.

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 Lender's interest in
the Collateral is not jeopardized in Lender's sole opinion. If the Collateral is
subjected to a lien which is not discharged within fifteen (1 5) 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, reasonable attorneys' fees or
other charges that could accrue as a result of foreclosure or sale of the
Collateral. In any contest Grantor shall defend itself and Lender and shall
satisfy any final adverse judgment before enforcement against the Collateral.
Grantor shall name Lender as an additional obligee under any surety bond
furnished in the contest proceedings. Grantor further agrees to furnish Lender
with evidence that such taxes, assessments, and governmental and other charges
have been paid in full and in a timely manner. 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
Lender's interest in the Collateral is not jeopardized.

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, including all laws or regulations relating to the undue
erosion of highly-erodible land or relating to the conversion of wetlands for
the production of an agricultural product or commodity. Grantor may contest in
good faith any such law, ordinance or regulation and withhold compliance during
any proceeding, including appropriate appeals, so long as Lender's interest in
the Collateral, in Lender'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 in violation of any Environmental Laws or for the generation,
manufacture, storage, transportation, treatment, disposal, release or threatened
release of any Hazardous Substance. The representations and warranties contained
herein are based on Grantor's due diligence in investigating the Collateral for
Hazardous Substances. Grantor hereby (1) releases and waives any future claims
against Lender for indemnity or contribution in the event Grantor becomes liable
for cleanup or other costs under any Environmental Laws, and (2) 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

                        COMMERCIAL SECURITY AGREEMENT
Loan No: 11325                   (Continued)                              Page 3

     Lender, 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 Lender so chooses "single interest insurance,"
     which will cover only Lender'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 be held 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 (1 5) 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 Lender 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 Lender, shall furnish to Lender
     reports on each existing policy of insurance showing such information as
     Lender may reasonably request including the following: (1) the name of the
     insurer; (2) the risks insured; (3) the amount of the policy; (4) the
     property insured; (5) the then current value on the basis of which
     insurance has been obtained and the manner of determining that value; and
     (6) 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.

     Financing Statements. Grantor authorizes Lender to file a UCC financing
     statement, or alternatively, a copy of this Agreement to perfect Lender's
     security interest. At Lander's request, Grantor additionally agrees to sign
     all other documents that are necessary to perfect, protect, and continue
     Lender's security interest in the Property. Grantor will pay all filing
     fees, title transfer fees, and other fees and costs involved unless
     prohibited by law or unless Lender is required by law to pay such fees and
     costs. Grantor irrevocably appoints Lender to execute documents necessary
     to transfer title if there is a default. Lender may file a copy of this
     Agreement as a financing statement. If Grantor changes Grantor's name or
     address, or the name or address of any person granting a security interest
     under this Agreement changes, Grantor will promptly notify the Lender of
     such change.

GRANTORS 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 Lender, 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 Lender'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.

LENDER'S EXPENDITURES. If any action or proceeding is commenced that would
materially affect Lender's interest in the Collateral or if Grantor fails to
comply with any provision of this Agreement or any Related Documents, including
but not limited to Grantor's failure to discharge or pay when due any amounts
Grantor is required to discharge or pay under this Agreement or any Related
Documents, Lender on Grantor's behalf may (but shall not be obligated to) take
any action that Lender deems appropriate, including but not limited to
discharging or paying all taxes, liens, security interests, encumbrances and
other claims, at any time levied or placed on the Collateral and paying 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 will become a part
of the Indebtedness and, at Lender'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 (1) the term of any
applicable insurance policy; or (2) 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. The Agreement also will secure payment of these amounts. Such right
shall be in addition to all other rights and remedies to which Lender may be
entitled upon Default.

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

     Payment Default. Grantor fails to make any payment when due under the
     Indebtedness.

     Other Defaults. Grantor fails 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 to comply with or to perform any term, obligation,
     covenant or condition contained in any other agreement between Lender and
     Grantor.

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

     Defective Collateralization. This Agreement or any of the Related Documents
     ceases to be in full force and effect (including failure of any collateral
     document to create a valid and perfected security interest or lien) at any
     time and for any reason. Insolvency. The dissolution or termination of
     Grantor's existence as a going business, the insolvency of Grantor, the
     appointment of a
<PAGE>

                        COMMERCIAL SECURITY AGREEMENT
Loan No: 11325                   (Continued)                              Page 4

     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 any collateral securing the Indebtedness. This
     includes a garnishment of any of Grantor's accounts, including deposit
     accounts, with Lender. However, this Event of Default shall not apply if
     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 Lender 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 by 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 Guarantor dies or becomes
     incompetent or revokes or disputes the validity of, or liability under, any
     Guaranty of the Indebtedness.

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

     Insecurity. Lender in good faith believes itself insecure.

     Cure Provisions. If any default~ other than a default in payment is curable
     and if Grantor has not been given a notice of a breach of the same
     provision of this Agreement within the preceding twelve (1 2) months, it
     may be cured if Grantor, after receiving written notice from Lender
     demanding cure of such default: (1) cures the default within fifteen (15)
     days; or (2) if the cure requires more than fifteen (15) days, immediately
     initiates steps which Lender deems in Lender'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. Lender may declare the entire Indebtedness,
     including any prepayment penalty which Grantor would be required to pay,
     immediately due and payable, without notice of any kind to Grantor.

     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. 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 Lender 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 Lender's 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, and other persons as required by law, reasonable notice of
     the time and place of any public sale, or the time after which any private
     sale or any other disposition of the Collateral is to be made. However, no
     notice need be provided to any person who, after Event of Default occurs,
     enters into and authenticates an agreement waiving that person's right to
     notification of sale. 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. Lender shall have the right to have a receiver appointed
     to take possession of all or any part of the Collateral, with the power to
     protect and preserve the Collateral, to operate the Collateral preceding
     foreclosure or sale, and to collect the Rents from the Collateral and apply
     the proceeds, over and above the cost of the receivership, against the
     Indebtedness. The receiver may serve without bond if permitted by law.
     Lender's right to the appointment of a receiver shall exist whether or not
     the apparent value of the Collateral exceeds the Indebtedness by a
     substantial amount. Employment by Lender shall not disqualify a person from
     serving as a receiver.

     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 Lender's discretion transfer any
     Collateral into Lender's own name or that of Lenders 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, choses 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, Lender 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, Lender may notify account debtors
     and obligors on any Collateral to make payments directly to Lender.

     Obtain Deficiency. If Lender 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.

     Election of Remedies. Except as may be prohibited by applicable law, all of
     Lender's rights and remedies, whether evidenced by this Agreement, the
     Related Documents, or by any other writing, shall be cumulative and may be
     exercised singularly or concurrently. Election by Lender 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 Grantor's failure to perform, shall not affect
     Lender's right to declare a default and exercise its remedies.

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of
this Agreement:

     Amendments. This Agreement, together with any Related Documents,
     constitutes the entire understanding and agreement of the parties as to the
     matters set forth in this Agreement. No alteration of or amendment to this
     Agreement shall be effective unless given in writing and signed by the
     party or parties sought to be charged or bound by the alteration or
     amendment.

     Attorneys' Fees; Expenses. Grantor agrees to pay upon demand all of
     Lender's costs and expenses, including Lender's reasonable
<PAGE>

                        COMMERCIAL SECURITY AGREEMENT
Loan No: 11325                   (Continued)                              Page 5

     attorneys' fees and Lender's legal expenses, incurred in connection with
     the enforcement of this Agreement. Lender may hire or pay someone else to
     help enforce this Agreement, and Grantor shall pay the costs and expenses
     of such enforcement. Costs and expenses include Lender's reasonable
     attorneys' fees and legal expenses whether or not there is a lawsuit,
     including reasonable 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. Grantor also shall pay all court costs and such additional fees
     as may be directed by the court.

     Caption Headings. Caption headings in this Agreement are for convenience
     purposes only and are not to be used to interpret or define the provisions
     of this Agreement.

     Lender and, to the extent not preempted by federal law, the laws of the
     State of Minnesota without regard to its conflicts of law provisions. This
     Agreement has been accepted by Lender in the State of Minnesota.

     No Waiver by Lender. Lender shall not be deemed to have waived any rights
     under this Agreement unless such waiver is given in writing and signed by
     Lender. 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
     Lender 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
     Lender, nor any course of dealing between Lender 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.

     Notices. Any notice required to be given under this Agreement shall be
     given in writing, and shall be effective when actually delivered, when
     actually received by telefacsimile (unless otherwise required by law), when
     deposited with a nationally recognized overnight courier, or, if mailed,
     when deposited in the United States mail, as first class, certified or
     registered mail postage prepaid, directed to the addresses shown near the
     beginning of this Agreement. Any party may change its address for notices
     under 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.
     For notice purposes, Grantor agrees to keep Lender informed at all times of
     Grantor's current address. Unless otherwise provided or required by law, if
     there is more than one Grantor, any notice given by Lender to any Grantor
     is deemed to be notice given to all Grantors.

     Power of Attorney. Grantor hereby appoints Lender as Grantor's irrevocable
     attorney-in-fact for the purpose of executing any documents necessary to
     perfect, amend, or to continue the security interest granted in this
     Agreement or to demand termination of filings of other secured parties.
     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 Lender's security interest in the
     Collateral.

     Severability. If a court of competent jurisdiction finds any provision of
     this Agreement to be illegal, invalid, or unenforceable as to any
     circumstance, that finding shall not make the offending provision illegal,
     invalid, or unenforceable as to any other circumstance. If feasible, the
     offending provision shall be considered modified so that it becomes legal,
     valid and enforceable. If the offending provision cannot be so modified, it
     shall be considered deleted from this Agreement. Unless otherwise required
     by law, the illegality, invalidity, or unenforceability of any provision of
     this Agreement shall not affect the legality, validity or enforceability of
     any other provision of this Agreement.

     Successors and Assigns. Subject to any limitations stated in this Agreement
     on transfer of Grantor's interest, this Agreement shall be binding upon and
     inure to the benefit of the parties, their successors and assigns. If
     ownership of the Collateral becomes vested in a person other than Grantor,
     Lender, without notice to Grantor, may deal with Grantor's successors with
     reference to this Agreement and the Indebtedness by way of forbearance or
     extension without releasing Grantor from the obligations of this Agreement
     or liability under the Indebtedness.

     Survival of Representations and Warranties. All representations,
     warranties, and agreements made by Grantor in this Agreement shall survive
     the execution and delivery of this Agreement, shall be continuing in
     nature, and shall remain in full force and effect until such time as
     Grantor's Indebtedness shall be paid in full.

     Time is of the Essence. Time is of the essence in the performance of this
