            Borrower.

2.2 Revolving Note. At the Closing, Borrower will execute and deliver to Bank
the Revolving Note in the form attached hereto as Exhibit A in the principal
amount of Two Million Dollars ($2,000,000.00) and Bank shall extend or make

conditions of this Agreement. Interest shall accrue on the unpaid principal
balance of the Revolving Note at an annual rate equal to the Citibank Prime Rate
plus one and one-half percent (1.50%) per annum, with such interest to be
calculated on the basis of a 360-day year counting the actual number of days
elapsed. The applicable rate of interest shall be adjusted immediately upon any
change in the Citibank Prime Rate. Interest shall be payable monthly commencing
on the first day of the month immediately succeeding the month during which the
first advance under the Revolving Note is made, and continuing on the first day
of each month thereafter. The entire unpaid principal balance plus all accrued
and unpaid interest on the Revolving Note shall be due and payable in full on
the Revolving Note Maturity Date.

2.3 Advances Under Revolving Note. Bank agrees, on the terms and subject to the
conditions of this Agreement, to advance funds to Borrower, and Borrower may
borrow, repay and reborrow within the limits of the Revolving Note from time to
time prior to the Revolving Note Maturity Date. No amount may be borrowed under

outstanding after giving effect to the advance requested by Borrower would
exceed the lesser of: (a) $2,000,000; or (b) the Borrowing Base as in effect at

Day, provided: (i) that Borrower shall have given Bank notice of its request (a
"Notice of Borrowing") prior to 2:00 p.m. of the Business Day on which the
advance is requested; and (ii) Borrower shall have provided Bank with a current
Borrowing Base Certificate. Each Notice of Borrowing shall specify the date of
the requested advance (which shall be a Business Day) and the principal amount
of the advance to be made (which shall be not less than $10,000, with increases
in increments of $1,000). Bank shall thereafter deposit the amount of the
requested advance into Borrower's operating account at Bank on the Business Day
specified in the Notice of Borrowing. Borrower acknowledges and agrees that
Borrower shall be limited to a maximum of two (2) advances per week under the
Revolving Note. Bank shall not be required to honor any request for an advance
under the Revolving Note other than as set forth in this Section 2.3.

reduce the outstanding principal balance of the Revolving Note shall depend on
whether the arrangements contemplated by the Lockbox Agreement have been
implemented and shall be made as follows:


                                     90
<PAGE>

      (a)   Payments Prior to Implementation of Lockbox. During those periods
            when the arrangements contemplated by the Lockbox Agreement have not
            been implemented by Bank, the timing and amount of payments made by
            Borrower to reduce the outstanding principal balance of the
            Revolving Note shall be within the discretion of Borrower. Borrower
            agrees to notify Bank by telephone or otherwise prior to 2:00 p.m.
            on any Business Day on which Borrower desires to make a payment to
            reduce the outstanding principal balance of the Revolving Note and
            Bank shall transfer funds from Borrower's operating account in
            accordance with the instructions provided by Borrower and apply such
            funds toward payment of the principal balance of the Revolving Note.
            Bank shall be under no obligation to make transfers from Borrower's
            operating account to make payments on the Revolving Note unless
            instructed to do so by Borrower in accordance with this Section
            2.4(a). Payments on the Revolving Note shall be applied in the
            manner specified In Section 2.4(b) below.

      (b)   Implementation of Lockbox and Payments Thereafter. Bank may, at its
            option, implement the arrangements contemplated by the Lockbox
            Agreement in the event: (i) the outstanding principal balance under
            the Revolving Note exceeds $1,000,000 for more than ninety (90)
            days; or (ii) any event occurs which, upon the giving of notice or
            the passage of time or both, would become an Event of Default
            hereunder; provided, however, that Bank shall notify Borrower of
            such event in writing and Borrower shall have a period of ten (10)
            days thereafter to cure such default prior to the implementation of
            the Lockbox Agreement by Bank. In the event that Bank shall be
            entitled under this Section 2.4(b) to implement the arrangements
            contemplated by the Lockbox Agreement, Borrower agrees to cooperate
            in establishing such arrangements and to take all action required of
            Borrower under the terms of the Lockbox Agreement. At such times as
            Bank may in its discretion deem appropriate (but in no event to
            exceed twice weekly), Bank shall, without the consent of, or notice
            to, Borrower, withdraw all collected funds then deposited in the
            cash collateral account and apply such funds to reduce the
            outstanding principal balance of the Revolving Note; provided,
            however, such funds may first be applied toward payment of late
            charges or costs of collection arising under the Revolving Note, if
            any, and then to past due interest payments on the Revolving Note,
            if any, with the remainder to be applied against the outstanding
            principal balance of the Revolving Note. Bank shall inform Borrower
            in writing of the amount withdrawn and applied to payment of the
            Revolving Note on each occasion.

2.5 Mortgage Note. At the Closing, Borrower will execute and deliver to Bank the
Mortgage Note in the form attached hereto Exhibit B in the principal amount of
One Million Dollars ($1,000,000.00) and Bank shall extend funds to Borrower in
such amount in accordance with the terms and conditions of this Agreement.
Interest shall accrue on the unpaid principal balance of the Mortgage Note from
the date of funding through the fifth anniversary of such date at an annual rate
equal to the Treasury Note Rate plus two and three-quarter percent (2.75%). The
applicable rate of interest shall be adjusted on the fifth anniversary of the
date of funding and on the same day every five years thereafter during the term
of the Mortgage Note, with such rate to be equal to the Treasury Note Rate then
in effect plus two and three-quarter percent (2.75%) per annum. All interest
will be calculated on the basis of a 360-day year counting the actual number of
days elapsed. Repayment of the Mortgage Note shall be amortized over a period of
fifteen (15) years, with payments of principal and interest to be made on the
first day of each month, commencing on June 1, 1994 and continuing on the first
day of each month thereafter. The entire unpaid principal balance plus all
accrued and unpaid interest on the Mortgage Note shall be due and payable in
full on the Mortgage Note Maturity Date.

2.6 Late Payments. In the event that any payment of principal or interest due
under the Notes, or repayment of any advance made by Bank pursuant to Section
2.9 of this Agreement, is not actually received by Bank within ten (10) days of
the date such payment is due, Borrower agrees to pay a late payment charge of
Twenty-five Dollars ($25.00).

2.7 Application of Payments. All payments received by Bank with respect to each
of the Notes shall be applied first to late charges and costs of collection, if
any, then to accrued and unpaid interest, and then to reduce the outstanding
principal balance of the respective Notes, except to the extent otherwise
provided in Section 2.4 hereof.

2.8 No Prepayment Penalty. In the event Borrower prepays any or all of the Notes
at a time earlier than provided for herein, no prepayment penalty shall be
assessed.

2.9 Advances by Bank. In the event Borrower shall fail to provide adequate
insurance, pay taxes or pay any other charges which may affect the Security
Property, Bank may, at its option, without notice, but without any obligation or
liability to do so, procure insurance, pay taxes or pay any other charges and
add said sum to the balance of any of the Notes, or divide such sum between the
Notes, as Bank shall determine in its sole discretion, which advance then shall
bear interest from the date of payment by Bank at the Citibank Prime Rate plus
one and one-half percent (1.50%) per annum. Any such advance and the interest
accrued thereon shall be paid to Bank on the last day of the month in which such
advance is made.

2.10 Loan Fee. At the Closing, the Borrower agrees to pay loan fees to Bank as
follows:

      (a)   A fee of Two Thousand Five Hundred Dollars ($2,500) for the loan

shall take place at the offices of Bank on or before June 30, 1994 and the
Mortgage Note shall be closed on or before December 31, 1994, or at such other
time and place as Bank and Borrower shall mutually agree.

2.12 Interest on Default. Upon the occurrence of an Event of Default hereunder,
the rate of interest payable on the Notes and on any advances made pursuant to
Section 2.9 hereof may, at Bank's option and in its sole discretion, be
increased to three percent (3%) per annum over the stated rate of the Notes.

                             Article III - Security

      To secure payment and performance of the Indebtedness, Bank shall receive
at the Closing the collateral and Guaranty set forth below:

upon the West Des Moines Real Estate owned by Borrower.

form attached hereto as Exhibit F to secure its obligations owing to Bank under
the terms of the Guaranty. Guarantor shall additionally execute and deliver to
Bank such financing statements as Bank may require in order to perfect the
security interest granted pursuant to the Guarantor Security Agreement.

or cause to be executed and delivered to Bank such security agreements,
financing statements, continuation statements, applications for notation of
security interests, title certificates, assignments and other documentation
which Bank shall require from time to time in connection with the attachment,

or assignments granted or to be granted to Bank hereunder. The Financing
Statements and the Mortgage may be prepared and filed prior to the Closing, and
Borrower and Guarantor agree to cooperate with Bank in the execution and filing
thereof prior to the Closing.

3.6 Priority of Liens. The security interests and mortgage lien granted to Bank
shall be and shall remain of the first priority at all times while any of the
Indebtedness remains unpaid or unperformed.

3.6 Cross Default and Cross Collateralization. Borrower acknowledges and agrees
that the Security Property shall secure repayment of all Indebtedness and that a
default in the terms of any of the Loan Documents shall constitute a default of
all of the Loan Documents, and that Bank may proceed in exercising its rights
under the Loan Documents in any order or manner as Bank may choose, the purpose
of this Agreement being to cross default cross collateralize all Indebtedness.

3.7 Acknowledgment. Borrower acknowledges that the terms of this Agreement
provide for a mortgage loan of fifteen years and a revolving loan maturing on
April 30, 1996. Borrower acknowledges and agrees that the Security Property
stands as collateral for all of the Notes and as security for all of the
Indebtedness. As a consequence, in the event that Bank elects not to renew the
Revolving Note after April 30, 1996, and Borrower deems it necessary to obtain
financing through a source other than Bank, it will be necessary for Borrower to
pay all of the Notes (including the Mortgage Note) in full in order to obtain a
release of the Security Property.

            governmental authority or any arbitration board or tribunal, which
            involves the possibility of any judgment or liability not fully
            covered by insurance or which may result in any material adverse
            change in the properties, business, prospects, profits or condition
            (financial or otherwise) of Borrower, nor is Borrower aware of any
            existing basis for any such action, suit or proceeding.

            assets purported to be owned by it, including that portion of the
            Security Property owned by it (and, in particular, the West Des
            Moines Real Estate), and all of such property is free and clear of
            any and all liens, claims, security interests and encumbrances
            whatsoever.

      (e)   Borrower is not aware of any default in the performance of any
            obligation, covenant or condition contained in any agreement to
            which it is a party, nor is Borrower in default with respect to any
            judgment, order, writ, injunction or decree of any court,
            governmental authority or arbitration board or tribunal.

      (f)   The execution, delivery and performance of this Agreement, the other
            Loan Documents and all documents and instruments referred to herein
            will not violate the provisions of the Articles of Incorporation or
            Bylaws of Borrower or of any note, indenture, mortgage, lease or
            other agreement to which Borrower is a party or by which it is
            bound, and will not result in the breach of any judgment, order,
            rule or regulation of any court or governmental agency having
            jurisdiction over Borrower or any of its properties. No consent,
            approval, authorization or order of any court or governmental agency

            which Borrower is a party or signatory, have been duly authorized by
            all appropriate proceedings of Borrower, and this Agreement and the
            other Loan Documents and all documents and instruments referred to
            herein to which Borrower is a party or signatory are valid and
            binding obligations of Borrower, enforceable in accordance with
            their respective terms.

      (h)   There exists on this date no Event of Default and no event or
            condition which, with notice or the lapse of time or both, would
            become an Event of Default.

      (i)   Borrower has filed all tax returns and reports required to be flied
            with the United States government and with all state and local
            governments which are required to be filed, and has paid in full, or
            made adequate provision on its books for the payment of, all taxes,
            interest, penalties, assessments, deficiencies, franchise fees and
            other governmental charges shown to be due or claimed to be due on
            or in respect of such tax returns or reports or otherwise levied

      (j)   Borrower is not in violation in any material manner of any federal,
            state, county or city statutes, ordinances, orders, rules or
            regulations pertaining to its business, and does not presently
            anticipate that future expenditures needed to meet the provisions of
            such federal, state, county or city statutes, ordinances, orders,
            rules or regulations will be so burdensome as to affect or impair in
            a materially adverse manner its financial condition.

      (k)   All of the funds loaned to Borrower pursuant to this Agreement will
            be used exclusively in Borrower's normal business operations and
            will not be diverted to or used in any other manner.

      (l)   To the extent that any of the Security Property is located in an
            area identified by the Secretary of Housing and Urban Development or
            a successor thereto as an area having special flood hazards pursuant
            to the terms of the National Flood Insurance Act of 1968, or the
            Flood Disaster Protection Act of 1973, as amended, or any successor
            law, Borrower has obtained and will maintain insurance on such
            Security Property protecting against such risk to the full extent of
            the value of such Security Property.

5.2 Environmental Matters. Borrower represents and warrants that: (a) to the
best of Borrower's actual knowledge, the Security Property (and all other
property now or heretofore owned by Borrower) and Borrower are now and
heretofore have been at all times in compliance with all Environmental Laws (as
hereinafter defined); (b) there have been no conditions on or about the Security
Property (or any other property now or heretofore owned by Borrower) which
required or will require clean-up, removal, remedial action or other response
pursuant to Environmental Laws; (c) there are no conditions on or about the
Security Property (or any other property now or heretofore owned by Borrower)
now existing or likely to exist during the term of this Agreement which require
or are likely to require clean-up, removal, remedial action, or other response
pursuant to Environmental Laws; (d) Borrower has never been and is not now a
party to any litigation or administrative proceeding, nor is any litigation or
administrative proceeding threatened against it, which asserts or alleges that
Borrower violated Environmental Laws; (e) to the best of Borrower's actual
knowledge, neither the Security Property (or any other property now or
heretofore owned by Borrower) nor Borrower is now or ever has been subject to
any judgment, decree, order or citation related to or arising out of
Environmental Laws; and (f) no permits or licenses are required under
Environmental Laws relative to the Security Property or Borrower.

      The term "Environmental Laws" shall mean all federal, state and local laws
including statutes, regulations, ordinances, codes, rules and other governmental
restrictions and requirements relating to the environment or hazardous
substances now or at any time hereafter in effect.

      Borrower covenants and agrees at all times while the Indebtedness remains
unpaid to (a) comply with all applicable Environmental Laws; (b) provide to
Bank, immediately upon receipt, copies of any correspondence, notice, pleading,
citation, indictment, complaint, order, decree, or other document from any
source asserting or alleging a circumstance or condition which requires or may
require a clean-up, removal, remedial action or other response by or on the part
of Borrower under Environmental Laws or which seeks criminal or punitive
penalties from Borrower for an alleged violation of Environmental Laws; and (c)
advise Bank in writing as soon as Borrower becomes aware of any condition or
circumstance which makes the foregoing covenants incomplete or inaccurate. In
the event of any such circumstance, Borrower agrees, at its expense and at the
request of Bank, to permit an environmental audit solely for the benefit of
Bank, to be conducted by Bank or an independent agent selected by Bank. This
provision shall not relieve Borrower from conducting its own environmental
audits or taking any other steps necessary to comply with Environmental Laws
which in the reasonable judgment of Bank is likely to impair materially the
value of the Security Property or the operations of Borrower. If in the opinion
of Bank there exists any provision of an Environmental Law


                                     96
<PAGE>

or any condition which requires, or may require, a clean-up, removal or other
remedial action by Borrower under any Environmental Laws and such clean-up,
removal or other remedial action is not completed within one hundred twenty
(120) days from the date of written notice from Bank to Borrower (or such longer
period as may be required under the circumstances), the name shall at the option
of Bank constitute a default hereunder.

      Borrower hereby agrees to defend, indemnify and hold Bank harmless from
and against any loss, liability, cost, damage, or expense, including, without
limitation, attorneys' fees, arising from the imposition or recordation of a
lien, the incurrence of any clean-up and removal costs under any Environmental
Laws with respect to the Security Property or Borrower, any liability to any
third party in connection with any violation of any Environmental Laws or other
action by Borrower or its agents or any diminution in value of the Security
Property as a result of any violation or alleged violation of any Environmental
Laws by Borrower.

            change in the properties, business, prospects, profits or condition
            (financial or otherwise) of Guarantor, nor is Guarantor aware of any
            existing basis for any such action, suit or proceeding.

      (d)   Guarantor is not aware of any default in the performance of any

            agreement to which Guarantor is a party or by which it is bound, and
            will not result in the breach of any judgment, order, rule or

      (e)   Borrower and Guarantor will maintain at all times proper books of
            record and account in accordance with Generally Accepted Accounting
            Principles, consistently applied, and permit Bank's officers or any
            of Bank's authorized representatives or accountants to visit and
            inspect their offices and property, examine their books of account
            and other records and discuss their affairs, finances and accounts
            with their officers, employees, accountants and auditors, all at
            such reasonable times and as often as Bank may desire. Bank will
            periodically audit Borrower's accounts receivable, inventory and
            accounts payable and Borrower agrees to pay Bank an hourly fee of
            $30.00 for time spent by Bank personnel performing such audits;
            provided, however, such fees shall not exceed $4,000 during any
            fiscal year. Moreover, if an Event of Default has occurred or is
            continuing, Borrower will pay the reasonable fees and disbursements
            of any accountants or other agent of Bank selected by Bank for the
            foregoing purposes (which fees shall not be subject to the $4,000
            annual limitation).

      (f)   In the event there are outstanding balances under the Revolving
            Note, Guarantor shall submit to Bank, within fifteen (15) days of
            the end of each calendar month, an unaudited balance sheet and
            income statement as of the end or the immediately preceding calendar
            month, prepared in accordance with Generally Accepted Accounting
            Principles consistently applied and certified as being true and
            correct by the president, chief financial officer or controller of
            Borrower.

            Note, Borrower shall, within fifteen (15) days of the end of each
            calendar month, submit to Bank a

            Compliance Certificate completed as of the end of the immediately
            preceding calendar month. The Compliance Certificate shall be
            submitted within fifteen (15) days of the end of each fiscal quarter
            during those periods when there is no outstanding balance under the
            Revolving Note.

      (h)   In the event there are outstanding balances under the Revolving
            Note, Borrower shall, within fifteen (15) days of the end of each
            calendar month, submit to Bank an account receivable aging report
            listing, for each outstanding account receivable as of the end of
            the immediately preceding calendar month, the account name, balance
            and payment status. Such report shall be submitted within fifteen
            (15) days of the end of each fiscal quarter during those periods
            when there is no outstanding balance under the Revolving Note.

      (i)   Within forty-five (45) days following the end of each fiscal
            quarter, Guarantor shall submit to Bank a copy of its Quarterly
            Report on Form 10-Q containing unaudited financial statements as of
            the end of such fiscal quarter, prepared in accordance with
            Generally Accepted Accounting Principles consistently applied.

      (j)   Within one hundred twenty (120) days following the end of each
            fiscal year, Guarantor shall submit to Bank its Annual Report on
            Form 10-K containing audited financial statements prepared in
            accordance with Generally Accepted Accounting Principles
            consistently applied and examined by an independent certified public
            accountant chosen by Guarantor and acceptable to Bank, which
            statements shall include a balance sheet, income statement,
            statement of cash flows, notes to financial statements and auditor's
            report.

      (k)   Guarantor shall, within ten (10) days of filing thereof with the
            Securities and Exchange Commission, provide Bank with copies of any
            Current Report on Form 8-K, any registration statement filed under
            the Securities Act of 1933 or any other report concerning a material
            event with respect to Borrower or Guarantor.

      (l)   Promptly upon receipt thereof, Borrower or Guarantor, as the case
            may be, will submit to Bank copies of all audit reports submitted by
            independent public accountants in connection with any special audit
            of the books of Borrower or Guarantor made by such accountants.

      (m)   Borrower and Guarantor further agree to supply to Bank such
            additional financial information as Bank may, from time to time,
            reasonably request to ascertain their respective financial
            conditions.

      (n)   Borrower or Guarantor, as the case may be, will, within five (5)
            days of receiving notice thereof, advise Bank in writing of any
            condition, event or act of the kind set forth in subparagraphs (1)
            through (4) below which comes to its attention that would or might
            prejudice Bank's rights under this Agreement or any other Loan
            Document:

                  (1) The filing of a lien, suit, action or other proceeding
            against Borrower or Guarantor wherein a claim is made in excess of
            Ten Thousand Dollars ($10,000.00);

                  (2) The filing, recording or assessment of a federal, state,
            or local tax lien against any of Borrower's or Guarantor's asset;


                                     102
<PAGE>

                  (3) The occurrence of any Event of Default or any act or event
            which, with notice or the lapse of time, or both, would constitute
            an Event of Default; or

                  (4) Any legal or administrative proceeding or investigation
            initiated against Borrower or Guarantor.

      (m)   Borrower will maintain, preserve and keep its buildings and
            properties and every part thereof in good repair, working order and
            condition and from time to time make all necessary repairs,
            renewals, replacements, additions, betterments and improvements
            thereto, so that at all times the efficiency thereof shall be fully
            preserved and maintained.

                  Article IX - Negative Covenants of Borrower

9.1 Covenants. So long as any part of the Indebtedness remains unpaid or any
obligations of Borrower or Guarantor under the Loan Documents remain
unsatisfied, Borrower and Guarantor covenant and agree that, without the prior
written consent of Bank (which shall not unreasonably be withheld), they shall
not:

      (a)   Merge or consolidate with any company or enterprise, or acquire or
            purchase any other company or enterprise, or suffer or permit the
            sale, lease, transfer or other disposition of a substantial part of
            Borrower's or Guarantor's properties or assets, unless replaced in
            the ordinary course of business with properties of substantially
            equal value. For purposes of the foregoing, any transaction
            involving the disposition of properties or assets having a value in
            excess of Two Hundred Fifty Thousand Dollars ($250,000) as measured
            by the consideration for the transaction in question shall be deemed
            to be substantial.

      (b)   Incur indebtedness for borrowed money, other than to Bank, or act as
            a guarantor for any indebtedness of others. For purposes hereof,
            entering into capital leases of personal property shall be deemed
            the incurring of indebtedness for borrowed money.

      (c)   Invest in, organize or participate in the organization or creation
            of any other business entity; provided, however, that Borrower
            and/or Guarantor shall be permitted to invest in and organize other
            business entities without the prior consent of Bank to the extent
            that; (i) the investment into any one business entity by Borrower
            and/or Guarantor does not exceed $250,000; and (ii) the investment
            into all business entities by Borrower and/or Guarantor does not
            exceed $750,000 in the aggregate at any one time.

      (d)   Redeem, retire, repurchase or otherwise acquire directly or
            indirectly any of Borrower's capital stock, or make any change in
            its capital structure, or pay or declare any dividend or other
            capital distribution, in cash or property, upon its capital stock.

      (e)   Change the general character of the business of Borrower or
            Guarantor as conducted on the date hereof and the Closing Date or
            engage in any type of business not reasonably related to such
            business as presently conducted.


                                     103
<PAGE>

      (f)   Permit the aggregate of all judgments or liens against Borrower
            and/or Guarantor at any one time to exceed Fifty Thousand Dollars
            ($50,000), whether aided by attachment or not, to remain unpaid,
            undischarged, unbonded or undismissed for a period of thirty (30)
            day.

      (g)   At any time permit Borrower or Guarantor to make any loans to
            others, including, but not limited to, any Affiliate or to any
            officer or employee of Borrower, Guarantor or an Affiliate, except
            that: (i) Borrower or Guarantor shall be permitted to make loans or
            extend credit to its officers or employees in an amount not to
            exceed $5,000 per person, provided, however, all such loans or
            extensions of credit by Borrower and/or Guarantor shall not exceed
            $50,000 in the aggregate at any given time; and (ii) the use of
            corporate credit cards for expenses incurred in the ordinary course
            of business shall not be deemed a loan or an extension of credit for
            purposes of this Section 9.1(g).

      (h)   Permit the pledge or encumbrance of any property of Borrower or
            Guarantor as security for any indebtedness incurred after the date
            of this Agreement except to Bank, with the exception of a purchase
            money security interest.

                  Article X - Additional Covenants of Borrower

10.1 Covenants. So long as any part of the Indebtedness remains unpaid or any
obligations of Borrower or Guarantor under the Loan Documents remain
unsatisfied, Borrower and Guarantor respectively covenant and agree with Bank as
follows:

      (a)   Guarantor agrees to maintain a Tangible Net Worth of not less than
            $4,500,000. "Tangible Net Worth" shall mean the amount of total
            assets (excluding the amount of Intangible Assets) less the amount
            of total liabilities (exclusive of Subordinated Debt, if any).
            "Intangible Assets" shall mean the book value of Guarantor's
            intangible assets including, but not limited to, goodwill, patents,
            trademarks, copyrights, secret processes, deferred expenses relating
            to general administrative, research and development expenses and all
            amounts due from any officer, employee, director, shareholder or
            Affiliate.

      (b)   Guarantor agrees to maintain a ratio of Debt to Tangible Net Worth
            of not more than 2.2 to 1.0 during the period commencing with the
            Closing Date and at all times thereafter, "Debt" shall mean all
            liabilities of Guarantor (less Subordinated Debt, if any). "Tangible
            Net Worth" shall have the meaning set forth in Section 10.1(a)
            hereof.

      (c)   Guarantor agrees to maintain Net Working Capital of not less than
            $1,500,000 and a Current Ratio of not less than 1.35 to 1.00. "Net
            Working Capital" shall mean the excess of Current Assets over
            Current Liabilities. "Current Ratio" shall mean the ratio of Current
            Assets to Current Liabilities. "Current Assets" shall mean the sum
            of cash, marketable securities, inventory at lower of cost or market
            and ordinary trade accounts receivable, excluding any amount due
            from any officer, employee, director, shareholder or Affiliate. In
            the event of a dispute relative to the carrying value of said
            inventory or accounts receivable, the determination thereof by an
            independent Certified Public Accountant chosen by Guarantor and
            acceptable to Bank shall be controlling. "Current Liabilities" shall
            mean any indebtedness due within one (1) year (exclusive of
            Subordinated Debt, if any), and any unsubordinated debt due to any
            officer, employee, director, shareholder or Affiliate. For purposes
            of this calculation, outstanding principal on Revolving Note shall
            be classified as a current liability.


                                     104
<PAGE>

      (d)   Borrower and Guarantor agree not to purchase, lease or otherwise
            acquire or enter into any commitment to purchase, lease or otherwise
            acquire additional capital assets where the aggregate liability or
            expenditure therefor in any one fiscal year exceeds ??? $500,000,
            except with the prior written consent by Bank.

      (e)   Any officer, employee, director, shareholder or Affiliate of
            Borrower or Guarantor shall subordinate all indebtedness including
            interest thereon (herein termed "Junior Indebtedness"), which may at
            any time now or hereafter be owed to any officer, employee,
            director, shareholder or Affiliate by Borrower or Guarantor in favor
            of the Indebtedness, including interest thereon. Borrower or
            Guarantor, as the case may be, shall obtain and deliver to Bank
            subordination agreements from said officers, employees, directors,
            shareholders or Affiliates for said Junior Indebtedness in form and
            content acceptable to Bank. Upon the occurrence of an Event of
            Default under this Agreement, Borrower or Guarantor, as the case may
            be, shall without notice from Bank immediately cease payment of any
            fees or advances to any officer, employee, director, shareholder or
            Affiliate and shall also cease payment of the sums, if any allowed
            to be paid by the terms of the subordination agreement(s).

      (f)   Borrower shall establish and maintain its principal deposit accounts
            at Bank as long as any Indebtedness remains outstanding or so long
            as this Agreement remains in effect.

                       Article XI - Default and Remedies

11.1 Default. Any one or more of the following events shall be considered an
"Event of Default" as that term is used herein:

      (a)   If Borrower should default in the payment of any principal, interest
            or any other sum payable under the Notes or hereunder (it is being
            understood that default in the payment of principal or interest of
            any of the Notes shall constitute default under all of the Notes),
            and such default shall not be cured within ten (10) days after
            written notice thereof is given by Bank to Borrower, provided,
            however, that Bank shall not be required to provide written notice
            of a default hereunder more than two times during any twelve
            consecutive month period.

      (b)   If a default occurs or there shall be non-compliance with any of the
            terms or provisions of any of the other Loan Documents.

      (c)   Non-payment when due of any Indebtedness.

      (d)   If any representation or warranty made by Borrower or Guarantor in
            any report or certification to Bank, in this Agreement or in any
            other Loan Document proves to be untrue or false in any material
            respect when made.

      (e)   If there shall be non-compliance with, or a breach of, any of the
            Affirmative Covenants contained in Article VIII hereof, any of the
            Negative Covenants contained in Article IX hereof, any of the
            Additional Covenants contained in Article X hereof, or any other
            covenant of Borrower or Guarantor set forth herein or in any other
            Loan Document, and such default, non-compliance or breach shall not
            be cured within ten (10) days in the case of a payment default, or
            thirty (30) days in the case of a non-payment default, after written
            notice thereof is given by Bank to Borrower.


                                     105
<PAGE>

      (f)   If: (i) Borrower or Guarantor shall be liquidated or dissolved or
            discontinue business; (ii) Borrower or Guarantor shall become
            insolvent or make an assignment for the benefit of creditors, or
            apply for or consent to the appointment of a receiver, trustee or
            liquidator for all of or a substantial portion of their respective
            assets; or (iii) any governmental agency or bankruptcy court or
            other court of competent jurisdiction shall assume custody or
            control of the whole or any part of the assets of Borrower or
            Guarantor and such action shall be consented to by Borrower or
            Guarantor, as the case may be, or shall remain undismissed for sixty
            (60) days.

      (g)   If a default occurs under Section 5.2 of this Agreement relating to
            environmental matters.

      (h)   If Bank reasonably believes that the prospect of payment of the
            Indebtedness is impaired due to acts or events materially and
            adversely bearing upon the financial condition of Borrower or
            Guarantor, or Bank on any other reasonable basis otherwise deems
            itself insecure.

11.2 Effect of Default; Cross Default. It is understood and agreed that any
Event of Default occurring under this Agreement or under any other Loan Document
shall constitute an event of default under each and every Loan Document. Upon
the happening of any Event of Default specified in Section 11.1 of this Article,
the entire amount owing under the Notes and the other Indebtedness, at the
option of Bank and without prior notice to Borrower or Guarantor, shall
thereupon mature and become immediately due and payable in full. In such event,
Bank may proceed to enforce payment in such manner as Bank may elect and realize
upon any and all rights of Bank in the Security Property. Additionally, without
prior notice to Borrower or Guarantor, Bank may appropriate and apply any and
all moneys in its possession, by deposit or otherwise, to the credit of or
belonging to Borrower or Guarantor, to any amounts owing to Bank under the
Notes, this Agreement, any of the other Loan Documents or the Indebtedness. Upon
the happening of any Event of Default, then in conjunction with, in addition to
or in substitution for those rights and remedies above described, and without
notice or demand which are, to the extent permitted by law, expressly waived,
the following shall be applicable:

      (a)   So long as it does not constitute a breach of the peace, Bank may
            enter upon any of Borrower's or Guarantor's premises to take
            possession of, assemble and collect the Security Property or to
            render it unusable;

      (b)   Bank may notify the account debtors or obligors of any accounts,
            chattel paper, negotiable instruments, general intangibles or other
            evidences of indebtedness in favor of Borrower or Guarantor to pay
            Bank directly and Bank may take control of the proceeds paid to
            Bank. Until Bank elects to exercise these rights, Borrower or
            Guarantor, as the case may be, is authorized to collect and enforce
            the collection of such accounts (subject to collection terms
            provided for in Section 2.4 hereof). The cost of collection and
            enforcement, including attorneys' fees and expenses, shall be borne
            solely by Borrower or Guarantor whether incurred by Bank or by
            Borrower or Guarantor;

      (c)   Bank may require Borrower or Guarantor to assemble the Security
            Property and make it available on Borrower's or Guarantor's premises
            or at a place Bank designates to allow Bank to take possession of or
            dispose of the Security Property;

      (d)   Bank may waive any Event of Default or remedy any Event of Default
            without waiving the Event of Default remedied and without waiving
            any other prior or subsequent Event of Default.


                                     106
<PAGE>

      (e)   Written notice given to Borrower or Guarantor, not less than ten
            (10) days prior to the date of public sale of the Security Property
            or prior to the date after which private sale or other disposition
            of the Security Property will be made, shall constitute reasonable
            notice;

      (f)   Bank may sell any unit of inventory or equipment at private sale or
            to a distributor or dealer at Borrower's current price for such
            inventory or at such lower price as may be then obtainable, which
            shall constitute disposition thereof in a commercially reasonable
            manner;

      (g)   It shall not be necessary that Bank take possession of the Security
            Property or any part thereof prior to the time that any sale
            pursuant to the provisions of this Section is conducted and it shall
            not be necessary that the Security Property or any part thereof be
            present at the location of such sale;

      (h)   Bank may proceed to protect and enforce its rights by any
            appropriate proceeding, whether for specific performance of any
            covenant or agreement contained in this Agreement or to enforce the
            payment of the Notes or other Indebtedness or to enforce any other
            legal or equitable right;

      (i)   Pursuant to the relevant procedures set forth in the UCC, Bank may
            take possession of the Security Property without the necessity for
            foreclosure proceedings and utilize and employ such procedures to
            protect the Security Property in such manner and for such length of
            time as Bank in its sole discretion may see fit. Borrower and
            Guarantor agrees that Bank shall not be liable for any damages
            resulting to Borrower or Guarantor from such actions; and

      (j)   Bank may cause the Mortgage to be foreclosed in the manner
            prescribed by law and upon the commencement of foreclosure
