                                 PROMISSORY NOTE

$500,000.00                                               Minneapolis, Minnesota
                                                                October 30, 2003

         1.       Agreement to Pay. FOR VALUE RECEIVED, the undersigned,
Automation, Manufacturing & Robotic Technologies, LLC, a Minnesota limited
liability company (hereinafter referred to as the "Borrower"), whose mailing
address is 2333 Waters Drive, Mendota Heights, Minnesota 55120, hereby agrees
and promises to pay to the order of M&I Marshall & Ilsley Bank, its endorsees,
successors and assigns (hereinafter sometimes referred to as the "Lender"), at
its principal office and mailing address at 651 Nicollet Mall, Minneapolis,
Minnesota 55402, or such other place as the Lender may from time to time
designate in writing, the principal sum of Five Hundred Thousand and no/100
Dollars ($500,000.00), or so much thereof as may from time to time be disbursed
hereon, together with interest on the unpaid principal balance at the rates
provided for herein, payable in lawful money of the United States of America
which shall be legal tender for public and private debts at the time of payment.

         2.       Interest Rate. The outstanding principal balance hereof shall
bear interest at a definite and certain but variable rate per annum (the
"Regular Rate") as set forth in the Credit Agreement (together with any
amendment thereto, the "Loan Agreement") between the Borrower and the Lender,
dated of even date herewith, providing terms and conditions on which the loan
evidenced by this Note (the "Loan") is to be made, as well as conditions to
disbursement of the Loan.

         3.       Late Charge. Any payment of principal, or interest not made by
the Borrower within ten (10) days of the due date thereof shall be subject to a
late payment charge equal to five percent (5%) of the amount not timely paid.
The late charge shall apply individually to all payments past due with no daily
adjustment and shall be used to defray the costs of the Lender incident to
collecting such late payment. This provision shall not be deemed to excuse a
late payment or be deemed a waiver of any other rights the Lender may have
including the right to declare the entire unpaid principal and interest
immediately due and payable.

         4.       Default Rate. Upon the occurrence of an Event of Default (as
defined in the Loan Agreement) at the Bank's option, the interest rate shall
thereafter increase and shall be payable on the whole of the unpaid principal
balance at a rate equal to three percent (3%) per annum in excess of the Regular
Rate (hereinafter referred to as the "Default Rate"), which Default Rate shall
be effective as of the date of the occurrence of such Event of Default. The
above increase in the interest rate upon the occurrence of an Event of Default
shall be applicable whether or not the Lender has exercised its option to
accelerate the maturity of this Note and declared the entire unpaid principal
indebtedness to be due and payable. The Default Rate shall continue until such
Event of Default is cured, payment in full of all indebtedness evidenced by this
Note, or completion of all foreclosure proceedings and redemption periods,
whichever shall occur first.

         5.       Monthly Payments. Principal and interest owing under this Note
shall be payable as follows:

                                     - 1 -
<PAGE>

         Interest only on the unpaid principal balance shall be due and payable
         in arrears on the last day of October, 2003, and on the same day of
         each month thereafter until October 30, 2004 (hereinafter referred to
         as the "Maturity Date"), on which date the entire unpaid principal
         balance together with all accrued interest shall become due and
         payable.

All payments shall be applied first to late charges, second to interest at the
rate then in effect under the terms hereof and third to principal, provided
however, that if any advance made by the Lender as the result of a default on
the part of the Borrower under the terms of this Note or any instrument securing
this Note is not repaid on demand, any monies received, at the option of the
Lender, may first be applied to repay such advances, plus interest thereon at
the Default Rate, and the balance, if any, shall be applied in accordance with
the provisions hereof.

         6.       Loan Documents; Security. This Note is given to evidence a
loan in the above amount and is the Note referred to in and/or secured by the
following (hereinafter referred to as the "Loan Documents"):

                  (a)      The Loan Agreement;

                  (b)      A Security Agreement (together with any amendment
         thereto, the "Security Agreement") given by the Borrower, as debtor, to
         the Lender, as secured party, dated of even date herewith, assigning to
         the Lender all of the Borrower's business assets; and

                  (c)      A Guaranty (together with any amendment thereto, the
         "Guaranty"), dated of even date herewith, from Aero Systems
         Engineering, Inc. in favor of the Lender; and

                  (d)      Any other documents evidencing or securing the Loan,
         together with any amendment thereto.

Reference is hereby made to the Loan Documents (which are incorporated herein by
reference as fully and with the same effect as if set forth herein at length), a
statement of the covenants and agreements, a statement of the rights and
remedies and securities afforded thereby and all other matters contained
therein.

         7.       Default and Acceleration; Waivers. The occurrence of an Event
of Default (as defined in the Loan Agreement), shall constitute an Event of
Default hereunder, and the entire unpaid principal balance together with accrued
interest at the Default Rate shall become, without notice, immediately due and
payable at the option of the Lender. No delay or omission on the part of the
Lender in exercising any right hereunder shall operate as a waiver of such right
or of any other remedy under this Note. A waiver on any one occasion shall not
be construed as a bar to or waiver of any such right or remedy on a future
occasion.

         8.       Prepayment Privilege.

         The indebtedness evidenced hereby may be prepaid in whole or in part at
any time without premium or penalty.

                                     - 2 -

         9.       Costs of Collection. The Borrower agrees that if, and as often
as, this Note is placed in the hands of an attorney for collection or to defend
or enforce any of the Lender's rights hereunder or under the Loan Agreement, the
Security Agreement or any other Loan Document securing payment of this Note, the
Borrower will pay to the Lender its attorneys' fees and all court costs
(including reasonable attorneys' fees and court costs prior to trial, at trial
and on appeal, or in any bankruptcy proceeding) and other expenses incurred in
connection therewith.

         10.      Time. Time is of the essence of this Note and each of the
provisions hereof.

         11.      Governing Law. This Note shall be governed by the laws of the
State of Minnesota.

         12.      Interest Limitation. All agreements between the Borrower and
the Lender are hereby expressly limited so that in no contingency or event
whatsoever, whether by reason of acceleration of maturity of the indebtedness
evidenced hereby or otherwise, shall the amount paid or agreed to be paid to the
Lender for the use, forbearance, loaning or detention of the indebtedness
evidenced hereby exceed the maximum permissible under applicable law. If from
any circumstances whatsoever, fulfillment of any provisions hereof or of the
Loan Agreement, the Security Agreement or any other Loan Document at any time
given shall exceed the maximum permissible under applicable law, then the
obligation to be fulfilled shall automatically be reduced to an amount which
complies with applicable law, and if from any circumstances the Lender should
ever receive as interest an amount which would exceed the highest lawful rate of
interest, such amount which would be in excess of such lawful rate of interest
shall be applied to the reduction of the principal balance evidenced hereby and
not to the payment of interest. This provision shall control every other
provision of all agreements between the Borrower and Lender and shall also be
binding upon and available to any subsequent holder of this Note.

         13.      Waivers. The Borrower, endorsers, sureties, guarantors and all
other persons liable for all or any part of the principal balance evidenced by
this Note severally waive presentment for payment, protest, notice of nonpayment
and notice of dishonor. Such parties hereby consent, without affecting their
liability, to any extension or alteration of the time or terms of payment
hereof, any renewal, any release of any or all of the security given for the
payment hereof, any acceptance of additional security of any kind, and any
release of, or resort to any party liable for payment hereof.

         14.      Disbursement. Funds representing the proceeds of the
indebtedness evidenced hereby which are disbursed by Lender by mail, wire
transfer or other delivery to the Borrower, to escrows or otherwise for the
benefit of the Borrower shall, for all purposes, be deemed outstanding hereunder
and to have been received by Borrower as of the date of such mailing, wire
transfer or delivery and until repaid, notwithstanding the fact that such funds
may not at any time have been remitted by such escrows to the Borrower or for
its benefit.

         15.      Captions. The captions to the Sections of this Note are for
convenience only and shall not be deemed part of the text of the respective
Sections and shall not vary, by implication or otherwise, any of the provisions
of this Note.

         16.      Notices. All notices required or permitted to be given
hereunder to Borrower or the Lender shall be given in the manner and to the
place as provided in the Loan Agreement.

         17.      WAIVER OF JURY TRIAL. THE LENDER BY ITS ACCEPTANCE HEREOF AND
THE BORROWER HEREBY VOLUNTARILY, KNOWINGLY AND INTENTIONALLY WAIVE ANY AND ALL
RIGHTS TO TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING ARISING UNDER THIS
NOTE OR CONCERNING THE INDEBTEDNESS EVIDENCED HEREBY AND/OR ANY COLLATERAL
SECURING SUCH INDEBTEDNESS, REGARDLESS OF WHETHER SUCH ACTION OR PROCEEDING
CONCERNS ANY CONTRACTUAL OR TORTIOUS OR OTHER CLAIM. THE BORROWER ACKNOWLEDGES
THAT THIS WAIVER OF JURY TRIAL IS A MATERIAL INDUCEMENT TO THE LENDER IN
EXTENDING CREDIT TO THE BORROWER, THAT THE LENDER WOULD NOT HAVE EXTENDED SUCH
CREDIT WITHOUT THIS JURY TRIAL WAIVER, AND THAT THE BORROWER HAS BEEN
REPRESENTED BY AN ATTORNEY OR HAS HAD AN OPPORTUNITY TO CONSULT WITH AN ATTORNEY
IN CONNECTION WITH THIS JURY TRIAL WAIVER AND UNDERSTANDS THE LEGAL EFFECT OF
THIS WAIVER.

         18.      Jurisdiction and Venue. The Borrower hereby irrevocably agrees
that any legal action or proceedings against it with respect to this Note may be
brought in the courts of the State of Minnesota, or in any United States
District Court in the State of Minnesota, and by the execution and delivery of
this Agreement, the Borrower hereby irrevocably submits to the jurisdiction of
each such court and hereby irrevocably waives any and all objections that the
Borrower may have as to jurisdiction or venue in any of such courts. The
Borrower acknowledges that it has received sufficient consideration for any
inconvenience which may be caused by any legal action brought in the State of
Minnesota, and agrees that the enforcement of the provisions of this Section
against the Borrower would not be unreasonable or unfair under all the
circumstances of the loan evidenced by this Note.

         19.      Entire Agreement. This Note and the Loan Documents contain the
entire agreement of the parties regarding the Loan. Without limiting the
generality of the foregoing, this Note and the Loan Documents supersede any term
sheet, loan application or commitment letter issued by the Lender or submitted
by the Borrower in connection with the Loan.

         20.      Business Purpose. The Borrower represents and warrants to the
Lender that the Borrower will use the proceeds of the Loan solely for business
purposes.

1. SECURITY INTEREST AND COLLATERAL. To secure the payment and performance of
each and every debt, liability and obligation of every type and description
which Debtor may now or at anytime hereafter owe to Secured Party (whether such

3. ADDITIONAL REPRESENTATIONS, WARRANTIES AND AGREEMENTS. Debtor represents,
warrants and agrees that:

         (a) Debtor has (or will have at the time Debtor acquires rights in
Collateral hereafter arising) absolute title to each item of Collateral free and
clear of all claims, security interests, liens and encumbrances and restrictions
on transfer and pledge, except the Security Interest and the interest of Fanuc
Robotics North America, Inc., in the following robots: M410HIS F52634, M4201A

of all persons other than Secured Party and the Fanuc Security Interest.. Debtor
will not sell or otherwise dispose of the Collateral or any interest therein
without the prior written consent of Secured Party, except that, until the
occurrence of an Event of Default and the revocation by Secured Party of
Debtor's right to do so, Debtor may sell any inventory constituting Collateral
to buyers in the ordinary course of business and equipment which is obsolete or
which is being replaced. If Debtor is a corporation, this Agreement has been
duly and validly authorized by all necessary corporate action, and, if Debtor is
a partnership, the partner(s) executing this Agreement has (have) authority to
act for the partnership.

         (b) Debtor will not permit any tangible Collateral to be located in any

statement covering such Collateral is required to be, but has not in fact been,
filed in order to perfect the Security Interest.

         (c) Each right to payment and each instrument, document, chattel paper
and other agreement constituting or evidencing Collateral is (or will be when
arising or issued) the valid genuine and legally enforceable obligation, subject
to no defense, set-off or counterclaim (other than those arising in the ordinary
course of business) of the account debtor or other obligor named therein or in
Debtor's records pertaining thereto as being obligated to pay such obligation.
Debtor will neither agree to any material modification or amendment nor agree to
any cancellation of any such obligation without Secured Party's prior written
consent, and will not subordinate any such right to payment to claims of other
creditors of such account debtor or other obligor.

         (d) Debtor will

         (i) keep all tangible Collateral in good repair, working order and
condition, normal depreciation excepted, and will, from time to time, replace
any worn, broken or defective parts thereof;

         (ii) promptly pay all taxes and other governmental charges levied or
assessed upon or against any Collateral or upon or against the creation,
perfection or continuance of the Security Interest;

         (iii) keep all Collateral free and clear of all security interests,
liens and encumbrances except the Security Interest and the Fanuc Security
Interest;

         (iv) at all reasonable times, permit Secured Party or its
representatives to examine or inspect any Collateral, wherever located, and to
examine, inspect and copy Debtor's books and records pertaining to the
Collateral and its business and financial condition and to send and discuss with
account debtors and other obligors requests for verifications of amounts owed to
Debtor;

                                     - 2 -
<PAGE>

         (v) keep accurate and complete records pertaining to the Collateral and
pertaining to Debtor's business and financial condition and submit to Secured
Party such periodic reports concerning the Collateral and Debtor's business and
financial condition as Secured Party may from time to time reasonably request;

         (vi) promptly notify Secured Party of any loss of or material damage to
any Collateral or of any adverse change, known to Debtor, in the prospect of
payment of any sums due on or under any instrument, chattel paper, or account
constituting Collateral;

         (vii) if Secured Party at any time so requests after the occurrence of
an Event of Default, promptly deliver to Secured Party any instrument, document
or chattel paper constituting Collateral, duly endorsed or assigned by Debtor;

         (viii) bear the risk of loss of the Collateral and at all times keep
all tangible Collateral insured against risks of fire (including so-called
extended coverage), theft, collision (in case of Collateral consisting of motor
vehicles) and such other risks and in such amounts as Secured Party may
reasonably request, with any loss payable to Secured Party to the extent of its
interest;

         (ix) pay when due or reimburse Secured Party on demand for all costs of
collection of any of the Obligations and all other out-of-pocket expenses
(including in each case all reasonable attorneys' fees) incurred by Secured
Party in connection with the creation, perfection, satisfaction, protection,
defense or enforcement of the Security Interest or the creation, continuance,
protection, defense or enforcement of this Agreement or any or all of the
Obligations, including expenses incurred in any litigation or bankruptcy or
insolvency proceedings;

         (x) execute, deliver or endorse any and all instruments, documents,
assignments, security agreements and other agreements and writings which Secured
Party may at any time reasonably request in order to secure, protect, perfect or
enforce the Security Interest and Secured Party's rights under this Agreement;

         (xi) not use or keep any Collateral, or permit it to be used or kept,
for any unlawful purpose or in violation of any federal, state or local law,
statute or ordinance; and

         (xii) not permit any tangible Collateral to become part of or to be
affixed to any real property without first assuring to the reasonable
satisfaction of Secured Party that the Security Interest will be prior and
senior to any interest, or lien then held or thereafter acquired by any
mortgagee of such real property or the owner or purchaser of any interest
therein.

If Debtor at any time fails to perform or observe any agreement contained in
this Section 3(d), and if such failure shall continue for a period of ten
calendar days after Secured Party gives Debtor written notice thereof (or, in
the case of the agreements contained in clauses (viii) and (ix) of this Section
3(d), immediately upon the occurrence of such failure, without notice or lapse
of time), Secured Party may (but need not) perform or observe such agreement on
behalf and in the name, place and stead of Debtor (or, at Secured Party's
option, in Secured Party's own name) and may (but need not) take any and all
other actions which Secured Party may reasonably deem necessary to cure or
correct such failure (including, without limitation, the payment of taxes, the
satisfaction of security interests, liens, or encumbrances, the performance of
obligations under contracts or agreements with account debtors or other
obligors, the procurement and maintenance of insurance, the execution of
financing statements, the endorsement of instruments, and the procurement of
repairs, transportation or insurance); and, except to the extent that the effect
of such payment would be to render any loan or forbearance of money usurious or
otherwise illegal under any applicable law, Debtor shall thereupon pay Secured
Party on demand the amount of all moneys expended and all costs and expenses
(including reasonable attorneys' fees) incurred by Secured Party in connection
with or as a result of Secured Party's performing or observing such agreements
or taking such actions, together with interest thereon from the date expended or
incurred by Secured Party at the highest rate then applicable to any of the
Obligations. To facilitate the performance or observance by Secured Party of
such agreements of Debtor, Debtor hereby irrevocably appoints (which appointment
is coupled with an interest) Secured Party, or its delegate, as the
attorney-in-fact of Debtor with the right (but not the duty) from time to time
to create, prepare, complete, execute, deliver, endorse or file, in the name and
on behalf of Debtor, any and all instruments, documents, financing statements,
applications for insurance and other agreements and writings required to be
obtained, executed, delivered or endorsed by Debtor under this Section 3 and
Section 4.

         (a) Debtor shall, from time to time, execute such financing statements
as Secured Party may reasonably require in order to perfect the Security
Interest. If any Collateral consists of a motor vehicle or other personal
property with a certificate of title, Debtor shall execute such documents as may
be required to have the Security Interest properly noted on a certificate of
title. Debtor shall execute, deliver or endorse any and all instruments,
documents, assignments, security agreements and other agreements and writings
which Secured Party may at any time reasonably request in order to secure,
protect, perfect or enforce the Security Interest and Secured party's rights
under this Agreement.

         (b) To the extent permitted by law, Debtor hereby authorizes Secured
Party to file one or more financing statements (each a "Financing Statement")
describing the Collateral or any agricultural liens or other statutory liens
held by Secured Party.

         (c) Debtor shall have possession of the Collateral, except where
expressly otherwise provided in this Security Agreement. Where collateral is in
the possession of a third party, Debtor will join with Secured Party in
notifying the third party of Secured Party's security interest and obtaining an
acknowledgement from the third party that it is holding the Collateral for the
benefit of the Secured party.

         (d) Debtor will cooperate with Secured Party in obtaining control with
respect to Collateral consisting of deposit accounts, investment property,
letter-of-credit rights and electronic chattel paper.

         (e) Debtor will not create any chattel paper without placing a legend
on the chattel paper acceptable to Secured Party that indicates that Secured
Party has a security interest in the chattel paper.

         (f) To the extent Debtor uses the Loan to purchase Collateral, Debtor's
repayment of the Loan shall apply on a "first-in, first-out" basis so that the
portion of the Loan used to purchase a particular item of Collateral shall be
paid in the chronological order the Debtor purchased the Collateral.

5. LOCK BOX, COLLATERAL ACCOUNT. If Secured Party so requests at any time after
the occurrence of an Event of Default, Debtor will direct each of its account
debtors to make payments due under the relevant account or chattel paper
directly to a special lock box to be under the control of Secured Party. Debtor
hereby authorizes and directs Secured Party to deposit into a special collateral
account to be established and maintained with or by Secured Party all checks,
drafts and cash payments, received in said lock box. All deposits in said
collateral account shall constitute proceeds of Collateral and shall not
constitute payment of any Obligation. At its option, Secured Party may at any
time after an Event of Default, apply finally collected funds on deposit in said
collateral account to the payment of the Obligations in such order of
application as Secured Party may determine, or permit Debtor to withdraw all or
any part of the balance on deposit in said collateral account. If a collateral
account is so established, Debtor agrees that it will promptly deliver to
Secured Party, for deposit into said collateral account, all payments on
accounts and chattel paper received by it. All such payments shall be delivered
to Secured Party in the form received (except for Debtor's endorsement where
necessary). Until so deposited, all payments on accounts and chattel paper
received by Debtor shall be held in trust by Debtor for and as the property of
Secured Party and shall not be commingled with any funds or property of Debtor.

6. ACCOUNT VERIFICATION AND COLLECTION RIGHTS OF SECURED PARTY. Secured Party
shall have the right to verify any accounts in the name of Debtor or in its own
name; and Debtor, whenever requested, shall furnish Secured Party with duplicate
statements of the accounts, which statements may be mailed or delivered by
Secured Party for that purpose. Notwithstanding Secured Party's rights under
Section 5 with respect to any and all debt instruments, chattel papers,
accounts, and other rights to payment constituting Collateral (including
proceeds), Secured Party may at any time (after the occurrence of an Event of
Default) notify any account debtor, or any other person obligated to pay any
amount due, that such chattel paper, account, or other right to payment has been
assigned or transferred to Secured Party for security and shall be paid directly
to Secured Party. If Secured Party so requests at any time after an Event of
Default, Debtor will so notify such account debtors and other obligors in
writing and will indicate on all invoices to such account debtors or other
obligors that the amount due is payable directly to Secured Party. At any time
after Debtor gives such notice to an account debtor or other obligor, Secured
Party may (but need not), in its own name or in Debtor's name, demand, sue for,
collect or receive any money or property at any time payable or receivable on
account of, or securing, any such chattel paper, account, or other right to
payment, or grant any extension to, make any compromise or settlement with or
otherwise agree to waive, modify, amend or change the obligations (including
collateral obligations) of any such account debtor or other obligor.

7. ASSIGNMENT OF INSURANCE. Debtor hereby assigns to Secured Party, as
additional security for the payment of the Obligations, any and all moneys
(including but not limited to proceeds of insurance and refunds of unearned
premiums) due or to become due under and all other rights of Debtor under or
with respect to, any and all policies of insurance covering the Collateral, and
Debtor hereby directs the issuer of any such policy to pay any such moneys
directly to Secured Party. After the occurrence of an Event of Default, Secured
Party may (but need not), in its own name or in Debtor's name, execute and
deliver proofs of claim, receive all such moneys, indorse checks and other
instruments representing payment of such moneys, and adjust, litigate,
compromise or release any claim against the issuer of such policy.

8. EVENTS OF DEFAULT. An event of default under that certain Credit Agreement
between Debtor and Secured Party dated the date hereof shall constitute an event
of default under this Agreement (herein called "Event of Default").

9. REMEDIES UPON EVENT OF DEFAULT. Upon the occurrence of an Event of Default
under Section 8 and at any time thereafter, Secured Party may exercise any one
or more of the following rights and remedies:

         (i) declare all unmatured Obligations to be immediately due and
payable, and the same shall thereupon be immediately due and payable, without
presentment or other notice or demand;

         (ii) exercise and enforce any or all rights and remedies available upon
default to a secured party under the Uniform Commercial Code, including but not
limited to the right to take possession of any Collateral, proceeding without
judicial process (without a prior hearing or notice thereof, which Debtor hereby
expressly waives), and the right to sell, lease or otherwise dispose of any or
all of the Collateral, and in connection therewith, Secured Party may require
Debtor to make the Collateral available to Secured Party at a place to be
designated by Secured Party which is reasonably convenient to both parties, and
if notice to Debtor of any intended disposition of Collateral or any other
intended action is required by law in a particular instance, such notice shall
be deemed commercially reasonable if given (in the manner specified in Section
11) at least 10 calendar days prior to the date of intended disposition or other
action;

         (iii) exercise or enforce any or all other rights or remedies available
to Secured Party by law or agreement against the Collateral, against Debtor or
against any other person or property. Upon the occurrence of the Event of
Default described in Section 8, all Obligations shall be immediately due and
payable without demand or notice thereof. Secured Party is hereby granted a
nonexclusive, worldwide and royalty-free license to use or otherwise exploit all
trademarks, trade secrets, franchises, copyrights and patents of Debtor that
Secured Party deems necessary or appropriate to the disposition of any
Collateral.

10. OTHER PERSONAL PROPERTY. Unless at the time Secured Party takes possession
of any tangible Collateral, or within seven days thereafter, Debtor gives
written notice to Secured Party of the existence of any goods, papers or other
property of Debtor, not affixed to or constituting a part of such Collateral,
but which are located or found upon or within such Collateral, describing such
property, Secured Party shall not be responsible or liable to Debtor for any
action taken or omitted by or on behalf of Secured Party with respect to such
property without actual knowledge of the existence of any such property or
without actual knowledge that it was located or to be found upon or within such
Collateral.

11. MISCELLANEOUS. This Agreement does not contemplate a sale of accounts, or
chattel paper. This Agreement can be waived, modified, amended, terminated or
discharged and the Security Interest can be released, only explicitly in a
writing signed by Secured Party. A waiver signed by Secured Party shall be
effective only in the specific instance and for the specific purpose given. Mere
delay or failure to act shall not preclude the exercise or enforcement of any of
Secured Party's rights or remedies. All rights and remedies of Secured Party
shall be cumulative and may be exercised singularly or concurrently, at Secured
Party's option, and the exercise or enforcement of any one such right or remedy
shall neither be a condition to nor bar the exercise or enforcement of any
other. All notices to be given to Debtor shall be deemed sufficiently given if
delivered or mailed by registered or certified mail, postage prepaid, to Debtor
at its address set forth above or at the most recent address shown on Secured
Party's records. Secured Party's duty of care with respect to Collateral in its
possession (as imposed by law) shall be deemed fulfilled if Secured Party
exercises reasonable care in physically safekeeping such Collateral or, in the
case of Collateral in the custody or possession of a bailee or other third
person, exercises reasonable care in the selection of the bailee or other third
person, and Secured Party need not otherwise preserve, protect, insure or care
for any Collateral. Secured Party shall not be obligated to preserve any rights
Debtor may have against prior parties, to realize on the Collateral at all or in
any particular manner

                                     - 5 -

or order, or to apply any cash proceeds of Collateral in any particular order of
application. Secured Party has no obligations to attempt to satisfy the
Obligations by collecting them from any other person liable for them and Secured
Party may release, modify or waive any collateral provided by any other person
to secure any of the Obligations, all without affecting Secured Party's rights
against Debtor. Debtor hereby waives any right it may have to require Secured
Party to pursue any third person for any of the Obligations. This Agreement
shall be binding upon and inure to the benefit of Debtor and Secured Party and
their respective heirs, representatives, successors and assigns and shall take
effect when signed by Debtor and delivered to Secured Party, and Debtor waives
notice of Secured Party's acceptance hereof. Secured Party may execute this
Agreement if appropriate for the purpose of filing, but the failure of Secured
Party to execute this Agreement shall not affect or impair the validity or
effectiveness of this Agreement. A carbon, photographic or other reproduction of
this Agreement or of any financing statement signed by the Debtor shall have the
same force and effect as the original for all purposes of a financing statement.
This Agreement shall be governed by the internal laws of the where the main
office of the Secured Party is located. If any provision or application of this
Agreement is held unlawful or unenforceable in any respect, such illegality or
unenforceability shall not affect other provisions or applications which can be
given effect and this Agreement shall be construed as if the unlawful or
unenforceable provision or application had never been contained herein or
prescribed hereby. All representations and warranties contained in this
Agreement shall survive the execution, delivery and performance of this
Agreement and the creation and payment of the Obligations. If this Agreement is
signed by more than one person as Debtor, the term "Debtor" shall refer to each
of them separately and to both or all of them jointly; all such persons shall be
bound both severally and jointly with the other(s); and the Obligations shall
include all debts, liabilities and obligations owed to Secured Party by any
Debtor solely or by both or several or all Debtors jointly or jointly and
severally, and all property described in Section 1 shall be included as part of
the Collateral, whether it is owned jointly by both or all Debtors or is owned
in whole or in part by one (or more) of them.
