             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
                          Medar, Inc. and Subsidiaries
                               September 30, 1998

Note A - Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. Operating results for the nine month period ended September 30,
1998 are not necessarily indicative of the results that may be expected for the
year ended December 31, 1998. For further information, refer to the consolidated
financial statements and footnotes thereto included in the Registrant Company
and Subsidiaries' annual report on Form 10-K for the year ended December 31,
1997.

Note B - Restructuring of Operations

Early in the second quarter of 1998, management completed an evaluation of
competitive conditions and product offerings in the vision and welding
divisions. A charge of $6,973,000 was recorded as of March 31, 1998 to give
effect to the impairment of assets identified in this review. The charge
consisted of $5,268,000 related to capitalized software development costs,
$1,402,000 related to inventory (included in direct costs of sales) and $303,000
of other accruals.

Note C - Comprehensive Income

During 1997, The Financial Accounting Standards Board issued Statement No. 130,
Reporting Comprehensive Income. This Statement establishes standards for the
reporting and display of comprehensive income and its components in a full set
of general purpose financial statements. The Company adopted Statement 130 as of
January 1, 1998. The adoption of this Statement had no impact on the Company's
net earnings (loss) or stockholders' equity. Statement 130 requires foreign
currency translation adjustments and unrealized gains or losses on investments
and certain derivative instruments, which prior to the adoption of Statement 130
were reported as a component of stockholders' equity, to be included in other
comprehensive income.

Total comprehensive income (loss) was ($1,029) and $725 for the three months
ended September 30, 1998 and 1997, respectively and ($10,820) and $340 for the
nine months ended September 30, 1998 and 1997, respectively.

Note D - Inventories

Inventories are stated at the lower of first-in, first-out cost or market, and
the major classes of inventories at the dates indicated were as follows:

Note E - Costs and Estimated Earnings in Excess of Billings on Incomplete 
         Contracts

Revenues on long-term contracts are recognized using the percentage of
completion method. The effects of changes to estimated total contract costs are
recognized in the period determined and losses, if any, are recognized fully
when identified. Costs incurred and earnings recognized in excess of amounts
billed are classified under current assets as costs and estimated earnings in
excess of billings on incomplete contracts. Long-term contracts include a
relatively high percentage of engineering costs and are generally less than one
year in duration.

Activity on long-term contracts is summarized as follows:

</TABLE>

The revolving note payable to bank is due August 31, 1999, and provides for
advances of up to $10,000,000 based upon levels of eligible accounts receivable
and inventory. At September 30, 1998, $10,000,000 was available for advances and
interest was at the bank's prime rate plus 1/4%. Substantially all company
assets not previously pledged under term notes (see below), have been pledged as
collateral for this indebtedness.

The term notes to bank are payable as follows:

- -    $62,500 quarterly plus interest at the bank's prime rate, plus 1/4%, due
     June 29, 2002; collateralized by a first mortgage on the Company's Grand
     River facility;
- -    $14,111 monthly, plus interest at 7.7%, due October 31, 2000;
     collateralized by a first mortgage on the Company's Crestview facility;
- -    $2,189 monthly, plus interest at the bank's prime rate, plus 1/4%;  due 
     March 20, 2002;

                                       8

The subordinated debentures mature $700,000 on each June 30 in the years 2000 to
2004, with the balance due June 30, 2005. Interest on the debentures is payable
quarterly at 12.95%. Substantially all company assets are secondarily pledged as
collateral for the debentures.

The debenture holders have warrants for the purchase of 1,400,000 shares of
Medar common stock at $6.86. These warrants expire June 30, 2005.

The agreements related to the revolving note and the subordinated debentures
require that the Company maintain certain levels of tangible net worth and
certain debt to equity ratios. At September 30, 1998, the Company did not meet
the required levels of net worth and debt to equity ratios in the agreements
related to the revolving note and subordinated debt. As such, the amounts due
under these notes have been classified as current. See further discussion of
this issue in "Management's Discussion and Analysis of Financial Condition and
Results of Operations - Liquidity and Capital Resources" elsewhere in this
document.

The patent license payable relates to future payments to a corporation for use
of certain patents. The payments are due in seven remaining installments and
have been discounted at 8%.

The fair values of these financial instruments approximates their carrying
amounts at September 30, 1998.

Maturities of long-term debt and capitalized lease obligations, excluding those
payable within twelve months form September 30, 1998 (which are stated as
current maturities of long-term debt) are $694,000 in 1999; $2,378,000 in 2000;
$549,000 in 2001, $554,000 in 2002, and $537,000, thereafter.

Note G - Income Taxes

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's deferred tax liabilities and assets are as follows:

Warrants to purchase 1,400,000 shares of common stock and options to purchase
662,100 shares of common stock were outstanding during 1998 but were not
included in the computation of diluted earnings per share because the inclusion
of these options would have an antidilutive effect.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS 
        OF OPERATIONS

Results of Operations
Three Months Ended September 30, 1998 Compared to September 30, 1997.

Net sales in the third quarter of 1998 decreased 18.4% to $8.9 million from
$11.0 million in 1997. The decrease resulted from decreases of resistance
welding product revenues of $.1 million and optical inspection revenues of $2.0
million. Optical inspection product revenues were down as the third quarter of
1997 revenues included the sale of licenses related to certain excess technology
for $1.5 million that did not recur in 1998 and from decreases in sales of CD
and DVD inspection products following management's first quarter decision to
stop pursuit of the CD market (see nine month discussion below) and slow
consumer acceptance of DVD products.

Gross margin decreased as a percentage of net sales to 28.7% from 33.5% in the
third quarter of 1997. Welding product gross margins were down principally as a
result of the effects of product mix. Vision product margins decreased as a
result of sales of excess technology licenses during the third quarter of 1997
quarter for which there was no recorded cost. The reduction in amortization of
software development costs following the product restructuring charges in the
first quarter of 1998 (see nine month discussion below) contributed positively
to vision product margins.

The sales backlog for the Company at September 30, 1998 was $4.8 million
compared to $9.2 million at September 30, 1997. Welding product backlogs are
lower than comparable 1997 levels, however, they are expected to strengthen in
the fourth quarter of 1998 as the Company books orders on projects for which its
products have been specified by the end user. Vision product backlogs are low
because of the historical buying patterns of vision customers who generally
expect expedited delivery of products following placement of the order.

Marketing expense decreased less than $.1 million from $1.0 million and as a
percentage of net sales increased to 10.9% from 9.2%. The increase in expenses
expressed as a percentage of net sales came principally from the continuation of
fixed costs with the decline in sales.

General and Administrative expense increased to $.8 million from $.7 million and
as a percentage of net sales increased to 9.0% from 6.2% The dollar increase is
principally related to the costs associated with the implementation of the
Company's new financial and manufacturing software. The percentage increase
results principally from the fixed nature of many general and administrative
expenses with the decrease in the level of net sales in 1998.

Research, development, and engineering expense increased to $1.3 million from
$.9 million and as a percentage of net sales to 14.1% from 7.8% in 1997. This
increase resulted from less software development costs meeting the criteria for
capitalization in 1998 as compared to 1997 as the development of VisionBlox and
DVD products are substantially completed. Many of the personnel formerly
dedicated to these products are now assigned directly to customer projects.

Net interest expense decreased to $.6 million from $.7 million in the prior year
due to reduced levels of borrowing during the quarter and as a percentage of net
sales to 6.5% from 6.0% due to lower sales.

Results of Operations
Nine Months Ended September 30, 1998 Compared to September 30, 1997.

Net sales in the nine months ended September 30, 1998 decreased 24% to $24.4
million from $32.2 million in 1997. The decrease resulted from decreases of
resistance welding product revenues of $2.8 million and optical inspection
revenues of $5.2 million. Welding product sales decreased as fewer large
automotive programs were scheduled in the period as compared to the first nine
months of 1997. Optical inspection 

                                       13
<PAGE>   14

product revenues were down due to decreases in sales of CD and DVD inspection
products due to the management's first quarter decision to stop pursuit of the
CD market, slow consumer acceptance of DVD products, and lower sales in Asia
caused by economic conditions in the region.

During the first quarter of 1998 in response to the financial conditions that
arose due to heavy investments necessary to complete certain projects under
development and unexpected low levels of orders and sales, management terminated
15% of the Company's employees with combined salaries totaling 20% of total
compensation. As these terminations severely constrained resources available for
product support, it was quickly followed by an extensive review of product
offerings. This review determined that the Company would concentrate its efforts
going forward toward products for the inspection of DVD discs, products based on
VisionBlox technology and certain higher margin and better selling welding
products. Other products including those related to compact disc production and
certain other products that were selling poorly or at low margins or which were
no longer supportable in the software configurations in use were identified for
phase out or abandonment. These products had recorded software development costs
totaling $5.3 million that was charged off to operations. In addition, reserves
totaling $1.4 million to reduce the cost of inventory related to these products
to estimated realizable value were established. Finally, in connection with a
decision to offer for sale one of the Company's buildings, a reserve was
established in the amount of $.3 million to cover the costs to carry the
building until the estimated sale date.

The charges related to inventory ($1.4 million) were recorded as part of direct
cost of sales and the charges related to software development costs and the
building reserve (totaling $5.6 million) were reflected as product restructuring
and other charges with other costs and expenses in the consolidated statements
of operations.

Gross margin in the nine-month period ended September 30, 1998 decreased as a
percentage of net sales to 21.6% from 30.4% in the comparable period 1997.
Welding product gross margins decreased as a result of lower levels of fixed
cost absorption during 1998 as the result of lower levels of production during
the period in response to lower order levels. Vision product margins decreased
as a result of lower levels of fixed cost absorption during the period. The
reduction in amortization of software development costs following the product
restructuring charges in the first quarter of 1998 contributed positively to
vision product margins.

Marketing expense decreased to $.3 million from $3.1 million and as a percentage
of net sales increased to 11.6% from 9.6%. The decrease in expenses expressed in
dollars came principally from reduction of expenditures related to CD products.
The increase in expenses expressed as a percentage of net sales came principally
from the continuation of fixed costs with the decline in sales.

General and Administrative expense increased to $2.3 million from $1.9 million
and as a percentage of net sales increased to 9.5% from 6.0%. The increase in
the dollars of expense results from certain classification changes from the
prior year, increases in legal expenses related to the final resolution of
several issues and legal activities related to the Companies product patents and
costs associated with implementation of the company's new financial and
manufacturing software. The percentage increase results from the classifications
and expense increases and from the fixed nature of many general and
administrative expenses with the decrease in the level of net sales in 1998.

Research, development, and engineering expense increased to $3.6 million from
$2.2 million and as a percentage of net sales to 14.8% from 6.9% in 1997. This
increase resulted from less software development expenses meeting the criteria
for capitalization in 1998 as compared to 1997 as the development of VisionBlox
and DVD products are substantially completed. Many of the personnel formerly
dedicated to these products are now assigned directly to customer projects.

Net interest expense increased to $1.8 million from $1.6 million in the prior
year and as a percentage of net sales to 7.4% from 5.1% due to lower sales
volumes combined with increased average debt and debt at higher interest rates.

Liquidity and Capital Resources

At September 30, 1998 the Company had a revolving note payable to bank, with a
scheduled due date of August 1999, subordinated debentures with scheduled due
dates 2000 through 2005 and various term notes that generally mature in 2 to 4
years. Levels of advances under the revolving note are based on levels of
acceptable accounts receivable and inventory. The revolving note payable
provides for advances of up to $10,000,000. At June 30, 1998 $10,000,000 was
available for advances of which $10,000,000 had been advanced. The Company is
prohibited from paying dividends under terms of the credit agreement.

The agreements related to the revolving note and the subordinated debentures
require that the Company maintain certain levels of tangible net worth and
certain debt to equity ratios. The Company did not meet the required levels of
at December 31, 1997; however, the bank and subordinated note holders waived the
shortfall at that date. At March 31, 1998, the Company again did not meet the
levels of tangible net worth and debt to equity ratios required in the
agreements. In May 1998, the bank agreed to revise the agreement and installed
new equity and ratios floors. Although discussions have continued, the
subordinated note holders have not agreed to any revisions of their agreement.
At September 30, 1998, the Company did not meet the revised required levels of
net worth and debt to equity ratios in the bank agreement and continued not to
meet the levels required in the note holder's agreement.

Management is currently in negotiations with both the bank and the note holders
in an attempt to resolve these matters. With respect to the bank, management is
attempting to obtain an extension into early 1999 of the current agreement. It
is anticipated that the bank will be replaced with another lending institution
at that time. Although management believes it will be successful in negotiating
an agreement with the bank, there is no assurance that an acceptable agreement
can be achieved. Additionally, at the present time, management is holding active
discussions with several lending institutions with the intention of replacing
the bank as senior lender. There, however, can be no assurance that an agreement
will be reached that will provide the type or level of credit that the Company
needs to sustain its operations. With respect to the note holders, the
management has continued to hold discussions regarding the covenants and is
hopeful that a resolution can be achieved. Meanwhile the note holders have not
elected to exercise any of the options available to them under the terns of the
lending agreement and they have not informed management of their intention to do
so.

The Company generated $4.0 million of cash from operations in the nine months
ended September 30, 1998. The cash was used principally to fund additions to
capitalize software and to reduce bank debt. The company has no material
commitments for the purchase of property and equipment or software development
costs. The amount of software development costs incurred and capitalized over
the remainder of 1998 will be dependent on determinations throughout the year of
the long and short-term revenue opportunities for the Company's various
products.

Under the assumption that the current negotiations with the bank and the note
holders are successful and that an acceptable new long-term lending arrangement
is obtained, management believes that the resources together with any cash
generated from operations are adequate to meet cash needs for the next twelve
months.

Agreement, NBD will make Revolving Loans to the Borrowers, jointly and
severally, on a revolving basis from the Effective Date and before the
Termination Date as the Borrowers may from time to time request from NBD;
provided, however, that the aggregate principal amount of all Revolving Loans
outstanding hereunder when added to the face amount of all then outstanding L/Cs
shall not at any time exceed the lesser of the (a) Commitment or (b) the
Borrowing Base at such time. 

                                       11

<PAGE>   17


The principal amount of each Revolving Loan shall be in an integral multiples of
$10,000 and shall be in an amount not less than $10,000. The Revolving Loans
advanced under this Section 2.1 shall be evidenced by a Revolving Note of the
Company in substantially the form of Exhibit 2.1. The Revolving Note shall be
dated the Effective Date and be due on the Termination Date. Interest shall
accrue on the unpaid principal balance of the Revolving Loans from time to time
outstanding under this Section 2.1 at the Floating Rate and shall be payable in
accordance with Article III. Subject to the other terms and conditions of this
Agreement the Revolving Loans may be borrowed, repaid and reborrowed prior to
the Termination Date. Although the Revolving Credit Note shall be expressed to
be payable in the maximum amount of the Commitment, the Borrowers shall be
obligated to pay only the unpaid balance of the Revolving Loans together with
interest thereon and other amounts due in connection therewith as provided
herein and in the Revolving Note. The proceeds of Revolving Loans shall be used
by the Borrowers for working capital or other general corporate purposes of the
Borrowers and/or Guarantors.

              (b)  Procedure for Borrowing. The Company shall give notice to the
Bank of each proposed Revolving Loan not later than 3:00 p.m., Detroit time, on
the proposed Funding Date. Each such request shall be effective upon receipt by
the Bank, shall be in writing or by telephone to be promptly confirmed in
writing, shall specify the Funding Date and amount of the requested Revolving
Loan. Each of the Borrowers hereby authorizes the Company to request Revolving
Loans and otherwise give and receive notices regarding the Loans and this
Agreement on its behalf. Subject to the terms and conditions of this Agreement,
the proceeds of each Revolving Loan shall be made available to the Borrowers by
depositing on the Funding Date the proceeds thereof, in immediately available
funds, in an account maintained by the Company or in Subsidiaries at the main
office of the Bank.

         2.2  Commitment Fee and Reducing Commitment.

              (a)  Commitment Fee. The Borrowers agree to pay to NBD a 
commitment fee computed at the rate of 1/2% per annum on the average daily
unused portion of the Commitment. The face amount of any outstanding standby L/C
issued pursuant Section 2.3 will be considered an amount used for purposes of
calculating such commitment fee, however, the face amount of any commercial L/C
will not be considered an amount used for purposes of calculating such
commitment fee. Such commitment fee will accrue from and after the Effective
Date, shall be calculated on a daily basis during the applicable period and will
be due and payable quarterly in arrears, beginning on September 30, 1998, and on
each December 31, March 31 and September 30 thereafter through the Termination
Date, with any accrued but unpaid commitment fee due on the Termination Date.

              (b)  Reducing and Terminating Commitment. The Borrowers will have
the right to terminate or reduce the Commitment at any time and from time to
time, in which case the Commitment will be terminated or permanently reduced by
the amount so specified, as the case may be; provided, however, that (a) the
Borrowers shall give notice of such termination or 


                                       12

<PAGE>   18


reduction to NBD at least five Business Days in advance thereof, specifying the
amount and effective date thereof, (b) each partial reduction of the Commitment
shall be in a minimum amount of $1,000,000 and in an integral multiple of
$100,000, (c) no such termination or reduction shall be permitted with respect
to any portion of the Commitment as to which a request for a Revolving Loan or a
L/C is then pending, and (d) the entire Commitment may not be terminated if any
Revolving Loans are then outstanding and may not be reduced below the sum of the
principal amount of Revolving Loans then outstanding plus the aggregate amount
of all then outstanding L/Cs. The Commitment or any portion thereof so
terminated or reduced pursuant to this Section 2.2(b) may not be reinstated.

         2.3  Letters of Credit

              (a)  Issuance of L/Cs. Provided there is sufficient availability
under the Borrowing Base and Commitment and if requested by the Borrowers (with
no less than three Business Days prior written application in such form as
requested by NBD), NBD shall issue for the account of any Borrower standby or
commercial letters of credit, upon the following conditions:

                   (i)   Total Amount. The total face amount of all outstanding
         L/Cs at any time shall not exceed an amount equal to the lesser, at
         such time, of (A) the L/C Sublimit or (B) the lesser of (1) the
         Commitment or (2) the Borrowing Base at such time.

                   (ii)  Expiry. The expiry date of any L/C shall not exceed a
         maximum of 12 months from the date of issuance, provided, however, that
         any L/Cs outstanding on the Termination Date will be (A) secured by
         cash or other collateral satisfactory to NBD, or (B) replaced as of the
         Termination Date under conditions which cause such outstanding L/Cs to
         be cancelled.

                   (iii) Fees. The Borrowers will be charged a $150 issuance fee
         for each standby L/C issued pursuant to this Section 2.3. Any
         outstanding standby will accrue a commission at a per annum rate of
         1.25% of the face amount of such L/C, payable annually in advance at
         time of issuance. All commercial L/Cs will incur the usual and
         customary charges, to be agreed upon by the Borrowers and NBD at the
         time of issuance, for the issuance of commercial L/Cs.

                   (iv)  Documentation. The Borrowers shall execute standard
         documentation as requested by NBD with respect to the issuance of each
         L/C.

                   (v)   Conditions Met. On the date of issuance, all of the
         conditions present specified in Sections 3.9 and 3.10 have been
         satisfied.

              (b)  Obligations Unconditional. The obligation of the to pay to 
NBD the amount of any L/C shall be absolute, unconditional and irrevocable and
shall remain in

                                       13

<PAGE>   19

full force and effect until all Obligations of the Borrowers shall have been
satisfied, and the Obligations with respect to each L/C shall not be affected,
modified or impaired upon the happening of any event, including, without
limitation, any of the following, whether or not with notice to, or the consent
of, the Borrowers:

                   (i)   Any lack of validity or enforceability of any L/C or 
         any other L/C Document or to any transaction related in any way to such
         L/C;

                   (ii)  Any amendment, modification, waiver, consent, or any
         substitution, exchange or release of or failure to perfect any interest
         in collateral or security, with respect to any of the L/C Documents;

                   (iii) The existence of any claim, setoff, defense or other
         right which any Borrower may have at any time against any beneficiary
         or any transferee of any L/C (or any persons for whom any such
         beneficiary or any such transferee may be acting), NBD or any other
         person or entity, whether in connection with any of the L/C Documents,
         the transactions contemplated herein or therein or any unrelated
         transactions;

                   (iv)  Any draft or other statement or document presented 
         under any L/C proving to be forged, fraudulent, invalid or insufficient
         in any respect or any statement therein being untrue or inaccurate in 
         any respect;

                   (v)   Payment by NBD to the beneficiary under any L/C against
         presentation of documents which do not strictly comply with the terms
         of the L/C, including failure of any documents to bear any reference or
         adequate reference to such L/C;

                   (vi)  Any failure, omission, delay or lack on the part of NBD
         or any party to any of the L/C Documents to enforce, assert or exercise
         any right, power or remedy conferred upon NBD or any such party under
         this Agreement or any of the L/C Documents, or any other acts or
         omissions on the part of NBD or any such party; and

                   (vii) Any other event or circumstance that would, in the
         absence of this clause, result in the release or discharge by operation
         of law or otherwise of the Borrowers from the performance or observance
         of any obligation, covenant or agreement contained in this Section 2.3.

              (d)  Repayment. The Borrowers agree, jointly and severally, to pay
to NBD, on the day on which any L/C shall come due, the face amount of such L/C
and all expenses paid or incurred by NBD relative thereto. Unless the Borrowers
shall have made such payment to NBD on such day, NBD shall be deemed to have
disbursed to the Borrowers and the Borrowers shall be deemed to have elected to
satisfy its repayment obligation by a Revolving Loan in an amount equal to the
amount due with respect to such L/C. Such Revolving Loan shall be 


                                       14

<PAGE>   20

disbursed notwithstanding any failure to satisfy any conditions for disbursement
of any Loan set forth in Section 3.10 and, to the extent of such Revolving Loan,
the repayment obligation of the Borrowers with respect to such L/C under this
subsection shall be deemed satisfied.

         2.4  Real Estate Loans. (a) NBD has extended a term loan to the Company
in the original principal amount of $2,540,000 ("1995 Mortgage Loan"), evidenced
by an Installment Business Loan Note in such amount, dated October 31, 1995
(together with any amendments, restatements, replacements or renewals, the "1995
Term Note"). In connection with the 1995 Mortgage Loan, the Company granted to
NBD a mortgage (the "1995 Mortgage") on the property commonly known as 24755
Crestview Court, Farmington Hills, Michigan, which the Company acknowledges
secures the 1995 Term Note, the other Obligations of the Borrowers under this
Agreement and any other amounts owed by the Company to NBD.

              (b)  NBD has extended a term loan to the Company in the principal 
amount of $2,500,000 ("1993 Mortgage Loan"), evidenced by a Term Note, dated
June 29, 1993 (together with any amendments, restatements, replacements or
renewals, the "1993 Term Note"). In connection with the 1993 Mortgage Loan, the
Company granted to NBD a mortgage (the "1993 Mortgage") on the property commonly
known as 38700 Grand River, Farmington Hills, Michigan, which the Company
acknowledges secures the 1993 Term Note, the other Obligations of the Borrowers
under this Agreement and any other amounts owed by the Company to NBD.

         2.5  NBD Records and Determinations. NBD is hereby authorized by the
Borrowers to note on NBD's books and records, the date and amount of each
Revolving Loan and Equipment Loan, the amount of each payment or prepayment on
any of the Loans and such other information as appropriate, which books and
records shall constitute prima facie evidence of the information so noted.
Notwithstanding the foregoing, the failure of NBD to record, or any error in
recording, any such information shall not relieve the Borrowers of their
obligation to repay the outstanding principal amount of the Loans, the L/Cs, all
accrued interest thereon and other amounts payable with respect thereto in
accordance with the terms of the Notes, the L/C Documents, and this Agreement.
NBD's determinations of the Applicable Rates, the Default Rate, the fees, any
indemnity payment or other amounts payable under this Agreement shall be
conclusive and binding absent manifest error.

                 ARTICLE III. PAYMENTS AND PREPAYMENTS OF LOANS

         3.1  Interest Rate and Method of Computation.

              (a)  Interest Rates. The outstanding principal balance of the 
Revolving Loans shall bear interest at the Floating Rate in effect from time
to time and 1995 Mortgage Loan and 1993 Mortgage Loan shall bear interest at the
Term Rate in effect from time to time; provided that if there is an Event of
Default or if any amount of principal and interest (to the extent legally
enforceable) that is not paid when due (whether at maturity, upon mandatory
prepayment, by acceleration or otherwise) shall bear interest, payable upon
demand, at the Default Rate or the

                                       15

<PAGE>   21

maximum rate permitted by law, whichever is lower, for the period commencing
on the due date thereof until the same is paid in full. In addition to the
foregoing, during the period that an Event of Default has occurred and shall be
continuing, the Borrowers shall pay on demand, at the election of the Bank,
interest at the Default Rate on the outstanding principal amount of all the
Obligations which are outstanding during such period from and after the date of
any such demand.

              (b)  Computations. All computations of interest and other
amounts due under this Agreement (including fees) shall be made on the basis of
a year of 360 days using the actual number of days occurring in the period for
which such interest or other amounts are payable, including the first day but
excluding the last day of the relevant period. Each determination by the Bank of
such amounts shall be presumed to be correct.

         3.2  Payment of Principal and Interest. The Borrowers shall pay all
accrued and unpaid interest on the outstanding principal balance of the
Revolving Loans on (i) the last day of each month and (ii) the Termination Date.
Principal and accrued and unpaid interest on the outstanding balance of the 1995
Mortgage Loan, the 1993 Mortgage Loan and the Existing Equipment Loan shall be
paid by the Borrowers as set forth in the corresponding Notes.

         3.3  Prepayment.

              (a)  Mandatory Prepayment. If the principal balance outstanding 
under Section 2.1 when added to the face amount of all outstanding L/Cs exceeds
the Commitment or the Borrowing Base at any time, the Borrowers shall
immediately prepay the amount of such excess to the Bank.

              (b)  Voluntary Prepayment of Notes. The Loans may be voluntarily 
prepaid in whole or in part at any time, without premium or penalty (except for
any fixed rate Equipment Loans which may be subject to a prepayment premium).
The Company, on behalf of the Borrowers, may designate the Note or Notes to
which a payment is to be applied and the Bank will apply such payment to the
Note or Notes so designated. In case of prepayment of less than all of the
outstanding principal amount of the Notes, the prepayment will be applied first
to accrued, but unpaid interest on the Note designated for prepayment by the
Company, and then to the principal amounts due on that Note, and if the
principal prepayments are to be made on the 1995 Mortgage Note, the 1993
Mortgage Note or on any Equipment Loan, then to installment payments of
principal in the inverse order of maturity.

         3.4  Manner, Time and Place of Payment. All payments (and prepayments
when required or permitted under Section 3.3) of principal, interest or fees
shall be made in Dollars in immediately available funds to the Bank at its
address set forth in this Agreement no later than 3:00 p.m., Detroit time, on
the dates when due. Any payments received after such time shall be deemed to
have been received on the following Business Day. If any payment under this
Agreement or any Note becomes due on a day other than a Business Day, its
maturity will be 



                                       16


<PAGE>   22

extended to the next succeeding Business Day, with interest continuing to accrue
on the unpaid principal.

         3.5  Authorization of Payments. If the Borrowers shall not otherwise
have made payment of any of the Obligations as provided in this Agreement, NBD
is expressly authorized to charge any such Obligations, when due, to any of the
Borrower's demand deposit accounts maintained with NBD or, if such accounts
shall not control sufficient funds, to any other account maintained by any
Borrower with NBD.

         3.6  No Setoff or Deduction. All payments of principal of and interest
on the Loans and other Obligations shall be paid by the Borrowers without setoff
or counterclaim, and free and clear of, and without deduction or withholding
for, or on account of, any present or future taxes, levies, imposts, duties,
fees, assessments, or other charges of whatever nature, imposed by any
governmental authority, or by any department, agency or other political
subdivision or taxing authority or other person.

         3.7  Payment on Non-Business Day; Payment Computations. Except as
otherwise provided in this Agreement, whenever any installment of principal of,
or interest on, any Loan or any other Obligation becomes due and payable on a
day which is not a Business Day, the maturity thereof shall be extended to the
next succeeding Business Day and, in the case of any installment of principal,
interest shall be payable thereon at the then Applicable Rate during such
extension.

         3.8  Conditions for Initial Loans. The obligation of NBD to make the

         4.1  Increased Costs. In the event that any Governmental Regulation now
or hereafter in effect and whether or not presently applicable to NBD, or any
interpretation or administration thereof by any governmental authority
(including without limitation the Board of Governors of the Federal Reserve
System) charged with the interpretation or administration thereof, or compliance
by NBD with any guideline, request or directive of any such authority (whether
or not having the force of law), shall (i) affect the basis of taxation of
payments to NBD of any amounts payable by the Borrowers under this Agreement or
any other Loan Documents (other than taxes imposed on the overall net income of
NBD, by the jurisdiction, or by any political subdivision or taxing authority of
any such jurisdiction, in which NBD has its principal office), or (ii) impose,
modify or deem applicable any reserve, special deposit or similar requirement
against assets of, deposits with or for the account of, or credit extended by
NBD, or (iii) impose any other condition with respect to this Agreement, the
Commitment, the Note, the Loans or any other Obligation, and the result of any
of the foregoing is to increase the cost to NBD of making, funding or
maintaining any Loan or to reduce the amount of any sum receivable by NBD under
this Agreement, then the Borrowers shall pay to NBD, from time to time, upon
request by NBD, additional amounts sufficient to compensate NBD for such
increased cost or reduced sum receivable. A statement as to the amount of such
increased cost or reduced sum receivable, prepared in good faith and in
reasonable detail by NBD and submitted by NBD to the Borrowers, shall be
conclusive and binding for all purposes absent manifest error in computation.

         4.2  Capital Requirements. In the event that any Governmental 
Regulation now or hereafter in effect and whether or not presently applicable to
NBD, or any interpretation or administration thereof by any governmental
authority (including without limitation the Board of Governors of the Federal
Reserve System) charged with the interpretation or administration thereof, or
compliance by NBD with any guideline, request or directive of any such authority
(whether or not having the force of law), including any risk-based capital
guidelines, affects or would affect the amount of capital required or expected
to be maintained by NBD (or any corporation controlling NBD) and NBD determines
that the amount of such capital is increased by or based upon the existence of
NBD's obligations hereunder and such increase has the effect of reducing the
rate of return on NBD's (or such controlling corporation's) capital as a
consequence of such obligations hereunder to a level below that which NBD (or
such controlling 


                                       19

<PAGE>   25

corporation) could have achieved but for such circumstances (taking into
consideration its policies with respect to capital adequacy) by an amount deemed
by NBD to be material, then the Borrowers shall pay to NBD, from time to time,
upon request by NBD, additional amounts sufficient to compensate NBD (or such
controlling corporation) for any increase in the amount of capital and reduced
rate of return which NBD reasonably determines to be allocable to the existence
of NBD's obligations hereunder. A statement as to the amount of such
compensation, prepared in good faith and in reasonable detail by NBD and
submitted by NBD to the Borrowers, shall be conclusive and binding for all
purposes absent manifest error in computation.

with respect to any Borrower, the Commitment shall automatically terminate
forthwith and all such amounts shall automatically become immediately due and
payable without notice; in all cases without demand, presentment, protest,
diligence, notice of dishonor or other formality, all of which are hereby
expressly waived.

              (b)  Other Remedies. Upon the occurrence and during the 
continuance of an Event of Default, NBD may exercise and enforce any and all
other rights and remedies available to it, whether arising under this Agreement

proceedings, whether for the specific performance (to the extent permitted by

or any other Loan Document or under applicable law.

              (c)  Set off. Upon the occurrence and during the continuance of 
any Event of Default, NBD (including the London Branch) may at any time and from

provisional or final) at any time held and other indebtedness at any time owing
by NBD to or for the credit or the account of any Borrower and any property of
any Borrower from time to time in possession of NBD, irrespective of whether or

such deposits, indebtedness and property as collateral security for the payment
and performance of the Obligations. The rights of NBD under this Section 7.2(c)

         8.1  Guaranty. Each Borrower hereby unconditionally and absolutely
guarantees to NBD the full and complete payment and performance when due of the

shall be referred to as "Guarantied Obligations" and the foregoing guaranty of
each Borrower shall be referred to as "Guaranty."

         8.2  Waivers and Consents. Upon the occurrence and during the
continuance of any Event of Default, NBD may enforce the Guaranty of any
Borrower independently of any other remedy, guaranty or security of NBD at any
time may have or hold in connection with the Guarantied Obligations. It will not
be necessary for NBD to proceed upon or against and/or exhaust any security or
remedy before proceeding to enforce the Guaranty of any Borrower. Each Borrower
expressly waives any right it may have to receive notice of acceptance by NBD,
any credit that NBD extends to the other Borrowers, default, demand and any
action or forbearance that NBD takes regarding any Borrower, any collateral or
any of the Guarantied Obligations which it might be entitled to by law or under
any other agreement. Each Borrower also waives any right to require NBD to
marshal assets in favor of any other Borrower or any other person or to proceed
against any other Borrower or any other guarantor of the Guarantied Obligations
or any collateral provided by any person. Each Borrower expressly waives any and
all defenses now or hereafter arising or asserted by reason of (i) any
disability or other defense of any other Borrower or any other guarantor for the
Guarantied Obligations with respect to the Guarantied Obligations, (ii) the
unenforceability or invalidity of any security for or guaranty of the Guarantied
Obligations or the lack of perfection or continuing perfection or failure of
priority of any security for the Guarantied Obligations, (iii) the cessation for
any cause whatsoever of the liability of any other Borrower or any other
guarantor of the Guarantied Obligations (other than by reason of the full
payment and performance of all Guarantied Obligations), (iv) any failure of NBD
to give notice of sale or other disposition of collateral to any other Borrower
or any other person or any defect in any notice that may be given in connection
with any sale or disposition of collateral, (v) any act or omission of NBD or
others that directly or indirectly results in or aids the discharge or release
of any other Borrower or any other guarantor of the Guarantied Obligations, or
of any security or guaranty therefor by operation of law or otherwise, (vi) any
failure of NBD to file or enhance a claim in any bankruptcy or other proceeding
with respect to any person, (vii) the avoidance of any lien or security interest
in favor of NBD for any reason, (viii) any bankruptcy, insolvency,
reorganization, arrangement, readjustment of debt, liquidation or dissolution
proceeding commenced by or against any person, including without limitation any
discharge of, or bar or stay against collecting, all or any of the Guarantied
Obligations (or any interest thereon) in or as a result of any such proceeding,
or (ix) any action taken by NBD that is authorized by this Section.

the part of NBD, nor any delay or failure on the part of NBD in exercising any
right, power or privilege hereunder or under any other Loan Document shall
operate as a waiver of such right, power or privilege or otherwise prejudice

any single or partial exercise thereof preclude any further exercise thereof 



                                       34

or the exercise of any other right, power or privilege. No right or remedy
conferred upon or reserved to NBD under this Agreement or under any other Loan

remedy granted thereunder or now or hereafter existing under any applicable law.
Every right and remedy granted by this Agreement or under any other Loan
Document or by applicable law to NBD may be exercised from time to time and as
often as may be deemed expedient by NBD and, unless contrary to the express
provisions of this Agreement or the other Loan Documents, irrespective of the

<PAGE>   42

              (b)  Suit in Other Jurisdictions. Nothing in Section 9.10(a) shall
affect the right of NBD to serve legal process in any other manner permitted by
law or affect the right of NBD to bring any action or proceeding against the
borrowers, the Guarantor or their respective property in the courts of any other
jurisdictions.

              (c)  Immunity. To the extent that such Borrower has or hereafter 
may acquire any immunity from jurisdiction of any court or from any service of
process (whether from service or notice, or otherwise) with respect to itself or

of its obligations under this Agreement, the Note and the other Loan Documents.

         9.11 Table of Contents and Headings. The table of contents and the
headings of the various Articles, Sections and paragraphs hereof are for the
convenience of reference only and shall in no way modify any of the terms or
provisions hereof.

         9.12 Construction of Certain Provisions. If any provision of this
Agreement refers to any action to be taken by any person, or which such person
is prohibited from taking, such provision shall be applicable whether such
action is taken directly or indirectly by such person, whether or not expressly
specified in such provision.

         9.13 Integration and Severability. This Agreement and the other Loan
Documents embody the entire agreement and understanding between the Borrowers
and NBD with respect to the revolving credit granted by NBD to the Borrowers,
and supersede all prior agreements and understandings, relating to the subject
matter hereof. In case any one or more of the obligations, of any of the
Borrowers under this Agreement or any other Loan Documents shall be invalid,
illegal or unenforceable in any jurisdiction, the validity, legality and
enforceability of the remaining obligations of the Borrowers shall not in any
way be affected or impaired thereby, and such invalidity, illegality or
unenforceability in one jurisdiction shall not affect the validity, legality nor
enforceability of the obligations of the Borrowers under this Agreement or any
other Loan Document in any other jurisdiction.

         9.14 Independence of Covenants. All covenants hereunder shall be given
independent effect so that if a particular action or condition is not permitted
by any such covenant, the fact that it would be permitted by an exception to, or
would be otherwise within the limitations of, another covenant shall not avoid
the occurrence of a Default or an Event of Default or any event or condition
which with notice or lapse of time, or both, could become such a Default or an
Event of Default if such action is taken or such condition exists.

         9.15 Joint and Several Liability.  All liabilities of the Borrowers
under this Agreement and the Notes shall be joint and several.

         9.16 Interest Rate Limitation. Notwithstanding any provisions of this
Agreement or any other Loan Document, in no event shall the amount of interest
paid or agreed to be paid by the Borrowers exceed an amount computed at the
highest rate of interest permissible under applicable law. If, from any
circumstances whatsoever, fulfillment of any provision of this Agreement or any
other Loan Document at the time performance of such provision shall be due,
shall involve exceeding the interest rate limitation validly prescribed by law
which a court of competent jurisdiction may deem applicable hereto, then, ipso
facto, the obligations to be fulfilled shall be reduced to an amount computed at
the highest rate of interest permissible under applicable law, and if for any
reason whatsoever NBD shall ever receive as interest an amount which would be
deemed unlawful under such applicable law such interest shall be automatically
applied to the payment of principal of the Loans outstanding hereunder (whether
or not then due and payable) and not to the payment of interest, or shall be
refunded to the Borrowers if such principal and all other Obligations of the
Borrowers to NBD have been paid in full.

         9.17 Limitation of Liability. Neither NBD nor any of its Affiliates,
directors, officers, agents, attorneys or employees shall be liable to the
Borrowers or any of the Borrower's Affiliates for any action taken, or omitted
to be taken, by it or them or any of them under this Agreement or any other Loan
Document or in connection herewith or therewith, except that no person shall be
relieved of any liability imposed by law for gross negligence or willful
misconduct. No claim may be made by the Borrowers or any of the Borrowers'
Affiliates against NBD, or any of its Affiliates, directors, officers, agents,
attorneys or employees, for any special, indirect, consequential or punitive
damages in respect of any breach or wrongful conduct (whether the claim is based
on contract or tort or duty imposed by law) arising out of or related to this
Agreement or any other Loan Document, or the transactions contemplated hereby or
thereby, or any act, omission or event occurring in connection herewith or
therewith. The Borrowers, on their own behalf and on behalf of their Affiliates,
hereby waive, release and agree not to sue upon any claim for any such damages,
whether or not accrued, and whether or not known or suspected to exist in its
favor.

         9.18 WAIVER OF JURY TRIAL. NBD AND EACH BORROWER, AFTER CONSULTING OR
HAVING HAD THE OPPORTUNITY TO CONSULT WITH COUNSEL, KNOWINGLY, VOLUNTARILY AND
INTENTIONALLY WAIVE ANY RIGHT ANY OF THEM MAY HAVE TO A TRIAL BY JURY IN ANY
LITIGATION BASED UPON OR ARISING OUT OF THIS AGREEMENT, THE NOTE OR ANY OTHER

$10,000,000                                                July 31, 1998
                                                           Detroit, Michigan

         FOR VALUE RECEIVED, the undersigned, MEDAR, INC. ("Medar"), and
INTEGRAL VISION, LTD. (collectively, "Borrowers"), jointly and severally, hereby
promise to pay to the order of NBD Bank, ("Bank"), pursuant to that Amended and
Restated Revolving Credit and Loan Agreement, entered into as of July 31, 1998
(the "Loan Agreement"), among Borrowers and Bank, at the main office of Bank in
Detroit, Michigan in accordance with the Loan Agreement, in immediately
available funds, the principal sum of Ten Million and 00/100 Dollars (U.S.
$10,000,000), or such lesser amount as is recorded on the books and records of
Bank, on August 31, 1999, or such later Termination Date as may be agreed to
under the Loan Agreement as amended from time to time, together with interest on
the outstanding balance thereof as provided in the Loan Agreement. Capitalized
terms used but not defined in this Note shall have the respective meanings
assigned to them in the Loan Agreement.

         Bank is hereby authorized by Borrowers to record on its books and
records, the date and amount of each Revolving Loan, the Loan Period, the
applicable interest rate (including any changes therein), the amount of each
payment of principal thereon and such other information as appropriate, which
books and records shall constitute rebuttable presumptive evidence of the
information so recorded, provided, however, that any failure by Bank to record
any such information shall not relieve Borrowers of their obligation to repay
the outstanding principal amount of all Revolving Loans made by Bank, all
accrued interest thereon and any amount payable with respect thereto in
accordance with the terms of this Note and the Loan Agreement. All payments of
principal and interest shall be made in lawful money of the United States of
America.

         This Note is subject to, and evidences the Revolving Loans made by Bank
under, the Loan Agreement, to which reference is hereby made for a statement of
the circumstances and terms under which all or a portion of this Note is subject
to prepayment and under which its due date may be accelerated and other terms
applicable to this Note. An Event of Default under the Loan Agreement
constitutes a default hereunder. During the period that any amount owing on this
Note is not paid in full when due (whether at stated maturity, by acceleration
or otherwise), such amount shall bear interest at the Default Rate applicable to
each Revolving Loan in effect from time to time or the maximum rate permitted by
law, whichever is lower, for the period commencing on the due date until the
same is paid in full. In addition to the foregoing, during the period that any
other Event of Default has occurred and shall be continuing, Borrowers shall pay
on demand, at the election of Bank, interest at the Default Rate or the maximum
rate permitted by law, whichever is lower, on the outstanding principal amount
of all the Obligations which are outstanding during such period from and after
the date of any such demand.

         This Revolving Note amends and restates, but does not satisfy, certain
existing obligations of the Borrowers evidenced by the Amended and Restated
Revolving Note in the 

<PAGE>   46

principal amount of $8,000,000 dated August 10, 1995, from Borrowers and
Automatic Inspection Devices, Inc. (which has since merged into Medar, Inc.) to
Bank.

         Borrowers and each endorser or guarantor hereof waive demand,
presentment, protest, diligence, notice of dishonor and any other formality in
connection with this Note. Borrowers further agree to pay, in addition to the
principal, interest and other sums due and payable hereon, all costs of
collecting this Note, including reasonable attorneys' fees and expenses.

         This Note is made under, and shall be governed by and construed in
accordance with, the laws of the State of Michigan applicable to contracts made
and to be performed entirely within the State of Michigan and without giving
effect to the choice of law principles of the State of Michigan.
