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 three month
period ended June 30, 1995 are not necessarily indicative of the results that
may be expected for the year ended December 31, 1995.  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, 1994.

Certain items in the 1994 financial statements have been reclassified to
conform with the corresponding 1995 presentation.

Note B - Acquisition of Integral Vision Ltd.
Effective January 1, 1995, the Company acquired 100% of the common stock and
preference shares of Integral Vision Ltd. (Integral) for 654,282 previously
unissued shares of Medar, Inc. common stock.  Integral is a machine vision
company located in the United Kingdom, which develops and manufactures
solutions for OEM's and end-users.  This transaction has been accounted for as
a pooling of interests and accordingly, the consolidated financial statements
for all periods presented have been restated to include the accounts of
Integral.

Note D - Costs and Estimated Earnings in Excess of Billings on Incomplete
Contracts
Revenues on long-term contracts are recognized using the percentage of
completion method based on the ratio of labor costs incurred to date on the
contract to estimated total labor costs for the contract.  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:

Note G - Stock Options
At June 30, 1995, there were options to purchase 798,912 shares outstanding
ranging in price from $1.50 to $11.50.  These options were not included in the
calculation of net loss per share, as the effect was antidilutive.


Note H - Settlement of Legal Proceedings
In July 1995, Medar, Inc. reached a settlement of its patent litigation which
was initiated by Square D Company in April of 1994 in the Federal District
Courts in Eastern District of Michigan and in Delaware.  This resolution also
settles claims made by Medar against Square D.  The terms of the settlement
made under the auspices of the Federal District Court in Delaware provide for a
cross license agreement on all single phase welding patents held by either
company and call for a single payment related to use of technology in prior
years as well as yearly payments for the use of technology in the future.

The single payment, which is expected to be paid in the third quarter of 1995,
has been recorded as an expense in the second quarter of 1995 and as a current
liability at June 30, 1995.  The future payments have been reflected as a
noncash transaction which increased both long-term debt and other assets by
$2,000,000.  This amount will be amortized over future periods.

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

Results of Operations
Three Months Ended June 30, 1995 Compared to June 30, 1994
Net sales increased $0.5 million (4.9%) to $11.2 million from $10.7 million.
This increase was due to an increase in volume of vision sales as the higher
demand for the Company's vision products continued.

Cost of sales increased to $7.7 million from $7.2 million and as a percentage
of net sales to 69.1% from 67.0%.  The increased percentage is primarily the
result of additional costs incurred related to the introduction of certain new
products and cost increases not recovered through sales price increases.

Sales backlog for the Company at June 30, 1995 was $16.8 million compared to
$4.3 million at June 30, 1994.  Most of the increase is due to receipt of a
large order from one of the Company's major customers.

Marketing expense increased to $1.2 million from $0.9 million and as a
percentage of net sales to 10.9% from 8.7%.  The increase was due to increased
personnel and promotional activity associated with new promotion programs and
product introductions.

General and administrative expense was relatively unchanged.

Research and development expense decreased to $0.3 million from $0.5 million
and as a percentage of net sales to 2.4% from 4.8% as a greater portion of
engineering time was spent on areas other than product development in 1995.

Patent litigation costs relate to costs of settlement of the Company's patent
litigation with Square D as well as the costs incurred to defend the case.

Net interest expense increased in 1995 from 1994 as 1994 was favorably impacted
by gains realized upon the sale of interest rate swaps.

The effective tax rate in 1995 increased over the rate used in 1994 due to the
utilization of net operating loss carryforwards in 1994.

Six Months Ended June 30, 1995 Compared to June 30, 1994
Net sales increased $2.6 million (13.2%) to $22.5 million from 19.9 million.
This increase was due to an increase in volume of vision sales as the higher
demand for the Company's vision products continued.

Cost of sales increased to $15.8 million from $13.3 million and as a percentage
of net sales to 70.3% from 66.9%.  The increased percentage is principally the
result of increased manufacturing costs not recovered through sales price
increases, costs incurred related to the introduction of certain new products
and changes in the mix of welding products.

Marketing expense increased to $2.3 million from $1.7 million and as a
percentage of net sales to 10.1% from 8.7%.  The increase was due to increased
personnel and promotional activity associated with new promotion programs and
product introductions.

General and administrative expense increased to $1.4 million from $1.1 million
and as a percentage of net sales to 6.2% from 5.7%.  The increase was primarily
due to additional support needed for expansion of the Company's U.K. facility.

Net interest expense increased in 1995 from 1994 as 1994 was favorably impacted

The effective tax rate in 1995 increased over the rate used in 1994 due to the
utilization of net operating loss carryforwards in 1994.

Liquidity and Capital Resources
The Company has a revolving note payable to its bank with a maximum balance of
$8,000,000.  This note expires June 29, 1997 and has advances which bear
interest at the bank's prime rate or a choice of other rates made available
under the terms of the agreement.

During the six months ended June 30, 1995, the Company utilized cash generated
from the sale of short-term investments and the proceeds from long-term
borrowings to fund investments in property and equipment and capitalized
software as well as the increase in inventory.  The increase in inventory is
primarily related to the increase in business activity in 1995.

The Company believes that current financial resources, together with cash
generated from operations, will be adequate to meet cash requirements through
1995.  The 1995 acquisition of Integral is not expected to significantly impact
the Company's financial resources. The Company does not currently anticipate
capital expenditures for which it would not be able to obtain appropriate
financing through the remainder of 1995.

                      ARTICLE II.   THE CREDIT FACILITIES

     2.1  Revolving Loan Commitment.

           (a) Commitment.  Subject to the terms and conditions of this
Agreement, NBD agrees to 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
which NBD shall be committed to have outstanding hereunder, when added to the
aggregate face amount of all outstanding L/Cs and Guaranties Issued by NBD,
shall not at any time exceed the Activated Amount.  The Revolving Loans,
whether payable in Dollars or Pounds Sterling, shall be evidenced by a
Revolving Note of the Company in the form of Exhibit 2.1.  The Revolving Note
shall be dated the Effective Date and stated to mature on the Termination Date.
Interest shall accrue on the unpaid principal balance of the Revolving Loans
from time to time outstanding at the Applicable Rate(s) and shall be payable in
accordance with Section 4.2.  Within the limits of the Activated Amount of the
Commitment and 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 Note shall be expressed to be payable





                                       11
<PAGE>   16

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.

     (b)  Tranche A.

          (i)   Activated Amount.  The "Activated Amount" shall be $5,000,000
on the Effective Date.  The Activated Amount may be increased by an amount
equal to all or a portion of the Unactivated Amount at Borrowers' option upon
compliance with the conditions set forth in Section 2.1(c).

          (ii)  Commitment Fee.  The Borrowers agree to pay to NBD a commitment
fee computed at the rate of 3/8% per annum on the average daily unused portion
of the Activated Amount.  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
or Guaranty Issued by NBD 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, 1995, and on each December 31, March 31, June 30 and September
30 thereafter through the Termination Date, with any accrued but unpaid
commitment fee due on the Termination Date.

     (c)  Tranche B.

          (i)   Amount of Credit.  The "Unactivated Amount" will be an amount
equal to the difference between the Commitment and the Activated Amount. The
Unactivated Amount may be added to the Activated Amount, in whole or in part,
by Borrowers sending at least three (3) Business Days prior written notice to
NBD specifying the portion of the Unactivated Amount that the Borrowers desire
to activate together with payment to NBD of the Activation Fee required by
Section 2.1(c)(iii).  The Unactivated Amount may be activated from time to time
in increments of $1,000,000.  Borrowers may not activate any portion of the
Unactivated Amount unless all conditions set forth in Section 3.6 and 3.7 are
met at the time of such activation and the Borrowers certify in writing all
such conditions are met and, once activated, such amount cannot be deactivated.

          (ii)  Commitment Fee.  The Borrowers agree to pay to NBD a commitment
fee computed at the rate of 1/8% per annum on the Unactivated Amount.  Such
commitment fee shall accrue from and after the Effective Date, shall be
calculated on a daily basis during the applicable period and shall be due and
payable quarterly in arrears, beginning on September 30, 1995 and on each
December 31, March 31, June 30 and September 30 thereafter through the
Termination Date, with any accrued but unpaid commitment fee due on the
Termination Date.  This commitment fee is in addition to any commitment fee due
under Section 2.1(b).





                                       12
<PAGE>   17

          (iii)      Activation Fee.  The Borrower agrees to pay to NBD upon
activation of any portion of the Unactivated Amount, an Activation Fee computed
at the rate of one quarter of one percent (1/4%) per annum on the portion of
the Unactivated Amount being activated for 90 days of a 360 day year.

     2.2  Termination and Reduction of the 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 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 or Guaranty
Issued by NBD is then pending, (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 and Guaranties Issued by NBD, and
(e) the reduction will first reduce the Unactivated Amount until it is reduced
completely and then reduce the Activated Amount.  The Commitment or any portion
thereof so terminated or reduced pursuant to this Section 2.2 may not be
reinstated.

     2.3  Letters of Credit and Guaranties Issued by NBD.

          (a)   Issuance of L/Cs.  Provided there is sufficient availability
under the Activated Amount 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 L/Cs when added to
     all outstanding Guaranties Issued by NBD at any time shall  not exceed an
     amount equal to the lesser, at such time, of (A) the L/C Sublimit or (B)
     the Activated Amount minus the aggregate principal balance of all then
     outstanding Revolving Loans.

                (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 1.00%
     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





                                       13
<PAGE>   18

     customary charges, to be agreed upon by the Borrowers and NBD at the time

     conditions present specified in Sections 3.6 and 3.7 have been satisfied.

          (b)   Guaranties Issued by the Bank.  Provided there is sufficient
availability under the Activated Amount, and if requested by the Borrowers
(with not less than three Business Days prior written application in such form
as required by NBD), NBD through the London Branch will issue for the account
of the Borrowers Guaranties Issued by NBD, upon the following conditions:

                (i)  Amount.  The aggregate amount of all outstanding
     Guaranties Issued by NBD when added to 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 Activated Amount minus the aggregate principal
     balance of all then outstanding Revolving Loans.

                (ii) Expiry.  The expiry date of any Guaranty Issued by NBD
     shall not exceed a maximum of 12 months from the date of issuance,
     provided, however, that any Guaranties Issued by NBD 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 Guaranties Issued by NBD to be
     cancelled.

                (iii)  Fees.  The Borrowers will pay the usual and customary
     charges to be agreed upon by the Borrowers and the London Branch at the
     time of issuance, for the issuance of each Guaranty Issued by NBD.

                (iv)  Documentation.  The Company shall execute such standard
     documentation as shall be requested by the London Branch with respect to
     the issuance of each Guaranty Issued by NBD.

                (v)  Conditions Met.  On the date of acceptance, all of the
     conditions precedent specified in Sections 3.6 and 3.7 shall have been
     satisfied.

          (c)   Obligations Unconditional.  The obligation of the Borrowers to
pay to NBD the amount of any L/C or Guaranty Issued by NBD shall be absolute,
unconditional and irrevocable and shall remain in full force and effect until
all Obligations of the Borrowers shall have been satisfied, and the Obligations
with respect to each L/C or Guaranty Issued by NBD 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 Company:

     Document or to any transaction related in any way to such L/C or Guaranty
     Issued by NBD;

                (ii)  Any amendment, modification, waiver, consent, or any

     Guaranty Issued by NBD against presentation of documents which do not

     omissions on the part of NBD or any such party; and

                (vii)  Any other event or circumstance that would, in the

to NBD, on the day on which any L/C or Guaranty Issued by NBD shall come due,

NBD may extend term loans to, or enter into leases or conditional sales
contracts with, either the Company or AID in a total amount not to exceed
$500,000 to be used for the acquisition of equipment.  All requests under this
Section 2.4 must be submitted in writing to NBD, together with all information
reasonably requested by NBD with respect to the equipment to be acquired.

          (b)   Term.  Each Equipment Loan will have a term as requested by

          (c)   Pricing of Term Loans.  The Borrowers will pay to NBD at the
time of funding any term loan, a closing fee equal to 1/4% of the principal
amount of such term loan.  Each term loan will bear interest at the Prime Rate

the outstanding principal amount of the Loans, the L/Cs, Guaranties Issued by
NBD, all accrued interest thereon and other amounts payable with respect
thereto in accordance with the terms of the Note, the L/C Documents, Guaranty

and each Base Rate Loan shall be at least pounds sterling 25,000 or a higher 
integral multiple of pounds sterling 25,000.

     3.2  Requests for Revolving Loans.  The Borrowers shall give NBD notice of
each proposed Revolving Loan: (a) in the case of a Floating Rate Loan, not
later than 3:00 p.m., Detroit time, on the proposed Funding Date of such

authorizes the Company to request loans and to otherwise give and receive
notices regarding the Loans and this Agreement on each Borrower's behalf.  Any
notice received after the hour specified above, shall be deemed to be notice
given prior to such hour, on the next succeeding Business Day.  Each such
request shall be effective upon receipt by NBD, shall be in writing or by
telephone to be promptly confirmed in writing (in either case, to be in the
form of Exhibit 3.2 for Floating Rate Loans, Base Rate Loans and Eurodollar
Rate Loans, and in the form of Exhibit 3.5 for Negotiated Rate Loans), shall
specify the Applicable Rate of the requested Revolving Loan, the Funding Date
and amount of the Revolving Loan for each Type of Loan and, for any Eurodollar
Rate Loan or Negotiated Rate Loan, the Loan Period thereof; provided that each
such request relating to a Base Rate Loan or Eurodollar Rate Loan to be funded
in Pounds Sterling shall be deemed effective only upon receipt by the London
Branch.  Subject to the terms and conditions of this Agreement, the proceeds of
each Revolving Loan shall be made available to the Borrowers by depositing the
proceeds thereof, in immediately available funds, in an account to be
designated by the Borrowers from time to time; provided, however, that NBD
shall have no obligation to make a Revolving Loan if, as a result of making
such loan, the aggregate principal amount of all outstanding Revolving Loans
(including the requested Revolving Loan) plus the aggregate amount of all
outstanding L/Cs and Guaranties Issued by NBD would exceed the Activated
Amount.

     3.3  Conversion of Revolving Loans; Procedures.  So long as no Default or
Event of Default exists and is continuing, the Borrowers may convert all or any
part of any outstanding Floating Rate Loan into a Negotiated Rate Loan or Base
Rate Loan into a Eurodollar Rate Loan, if available, by giving notice to NBD of
such conversion not later than 3:00 p.m., Detroit time, or, with respect to
Loans funded in Pounds Sterling, 11:00 a.m., London time, on the date of the





                                       17
<PAGE>   22

requested conversion.  Each such notice shall be effective upon receipt by NBD,
shall be in writing or by telephone to be promptly confirmed in writing (in
either case, to be in the form of Exhibit 3.2), shall specify the date and
amount of such conversion, the total amount of Loans to be so converted and the
Loan Period therefor.  Each conversion of a Floating Rate Loan or a Base Rate
Loan into a Fixed Rate Loan shall be on a Business Day, and in an amount as
provided in Section 3.1.

     3.4  Procedures at End of Loan Period.

          (a)   Automatic Conversion.  Unless the Borrowers request a new
Negotiated Rate Loan or Eurodollar Rate Loan in accordance with subsection (b)
below or repay the applicable Loan, NBD shall automatically and without request
by the Borrowers, on the last day of the applicable Loan Period, (i) convert
each Negotiated Rate Loan to a Floating Rate Loan and (ii) convert each
Eurodollar Rate Loan to Base Rate Loan.

          (b)   Extension.  So long as no Default or Event of Default exists
and is continuing, and subject to the limitations set forth in Section 2.1, the
Borrowers may cause all or any part of any outstanding Negotiated Rate Loan or
Eurodollar Rate Loan to continue to bear interest at a Negotiated Rate or an
Adjusted Eurodollar Rate, as the case may be, if available, at the end of the
then-applicable Loan Period, by (i) with respect to Negotiated Rate Loans,
notifying NBD in Detroit not later than 3:00 p.m., Detroit time, the first day

                ARTICLE IV.    PAYMENTS AND PREPAYMENTS OF LOANS

     4.1  Principal Payments.

          (a)   Final Payment of Loans.  Unless earlier payment is required
under this Agreement, the Borrowers shall pay to NBD on the Termination Date
the outstanding principal amount of the Revolving Loans and provide cash
collateral for, or obtain the cancellation of, all outstanding L/Cs and
Guaranties Issued by NBD.

          (b)   Optional Prepayment.  The Company may at any time and from time
to time prepay all or a portion of the Revolving Loans, without premium or
penalty; provided, however, that each prepayment of a Floating Rate Loan shall
be in a minimum amount of $25,000 and in an integral multiple of $25,000 and
each prepayment of a Base Rate Loan shall be in a minimum amount of pounds 
sterling 25,000 and in integral multiple of pounds sterling 25,000; and 
provided further that any prepayment of a Eurodollar Rate Loan which is made on 
a day other than the last day of a Loan Period or, with respect to a Negotiated 
Rate Loan, the maturity date thereof shall be accompanied by the indemnity 
payment set forth in Section 4.8 below.

          (c)   Mandatory Prepayment; Currency Fluctuations; Application.
Notwithstanding the limitations in Section 2.1, if at any Funding Date or at
any other time NBD shall notify the Borrowers in writing, the sum of the
aggregate outstanding principal amount of the Revolving Loans plus the
aggregate amount of all then outstanding L/Cs and Guaranties Issued by NBD
computed in Dollars at NBD's exchange rate then in effect exceeds 105% of the
Activated Amount, the Borrowers shall forthwith pay to NBD an amount not less
than the amount of any such excess for application to the outstanding principal
amount of the Revolving Loans.  Each such prepayment shall be made in Dollars
and/or Pounds Sterling, as appropriate, in a sufficient amount to prepay first
the Floating Rate Loans and Base Rate Loans which are then outstanding until
payment in full thereof or such excess is repaid.  If any such prepayment
prepays the Floating Rate Loans and Base Rate Loans in full, the balance of the
required prepayment shall be made in Dollars and applied against any Negotiated
Rate Loans which are then outstanding, and finally, if necessary, made in
Pounds Sterling and applied against any Eurodollar Rate Loans then outstanding.

          (d)   Application of Prepayments; Interest.  Except as otherwise
provided in Section 4.1(c) or 4.3(a), the Revolving Loans and Base Rate to
which any prepayments are to be applied shall be selected by NBD in its sole
discretion.  The Company shall also pay to NBD, together with such amounts, all
accrued interest to the date of payment on any Loans so prepaid and, with
respect to any Fixed Rate Loan prepaid prior to the end of the applicable Loan
Period or maturity date, the indemnity payment set forth in Section 4.8 below.

     on Floating Rate Loans and Base Rate Loans shall be payable: (A) on each

the Default Rate or the maximum rate permitted by law, whichever is lower, on
the outstanding principal amount of any Loan and any other amount payable by
the Borrowers hereunder (other than interest) which is not paid in full when
due (whether upon demand, at stated maturity, by acceleration or otherwise) 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 any other Event of Default
has occurred and shall be continuing, the Borrowers shall pay on demand, at the
election of NBD, 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.

     4.3  Payment Method and Related Matters.

          (a)   Payments by the Borrowers.  All payments to be made by the
Borrowers hereunder will be made in Dollars and in immediately available funds
to NBD at NBD's address set forth opposite its name on the signature page of
this Agreement, not later than 3:00 p.m., Detroit time, on the date on which
such payment shall become due; provided that payments with respect to Loans
funded through the London Branch and Guaranties Issued by NBD will be made in
Pounds Sterling in immediately available funds to NBD at the London Branch not
later than 12:00 noon, London time, on the date on which such  payment shall
become due.  Payments received after the hour specified above shall be deemed
to be payments made prior to such hour on the next succeeding Business Day.  At
the time of making each such payment, the Borrowers shall specify to NBD the
obligation of the Borrowers hereunder to which such payment is to be applied,
or, in the event that the Borrowers fails to so specify or if an Event of
Default shall have occurred and be continuing, NBD may apply such payments as
it may determine in its sole discretion.

          (b)   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.





                                       23
<PAGE>   28


     4.4  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.

     4.5  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. Computations of interest and other amounts due under this Agreement
shall be made on the basis of a year of 360 days, for the actual number of days
elapsed, including the first day but excluding the last day of the relevant
period.

     4.6  Additional Costs.

          (a)   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 and the Bank of England) 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 providing its Commitment or 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.

          (b)   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 and the Bank of England) charged with the interpretation or
administration thereof, or compliance by NBD with any guideline, request or





                                       24
<PAGE>   29

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 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.

     4.7  Illegality and Impossibility.

          (a)   Repayment.  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 the Board of  Governors Reserve System and the Bank of England)
charged with the interpretation or administration thereof, or compliance by NBD
with any request or directive of such authority (whether or not having the
force of law), including exchange controls, shall make it unlawful or
impossible for NBD to maintain any Eurodollar Rate Loan at the Adjusted
Eurodollar Rate or any Base Rate Loan at the Adjusted Base Rate under this
Agreement, the Borrowers shall, upon receipt of notice thereof from NBD, repay
in full to NBD the then outstanding principal amount of such Eurodollar Rate
Loan or such Base Rate Loan, as the case may be, together with all accrued
interest thereon to the date of payment and all amounts due to NBD under
Section 4.8, (i) on the last day of the then current Loan Period applicable to
the Loan if NBD may lawfully continue to maintain such Loan at the Adjusted
Eurodollar Rate or the Adjusted Base Rate, as the case may be, to such day, or
(ii) immediately if NBD may not continue to maintain such Loan at the Adjusted
Eurodollar Rate or the Adjusted Base Rate, as the case may be, to such day.

          (b)   Conversion of Eurodollar Rate Loans to Floating Rate Loans.
Notwithstanding Section 4.7(a), if such Section would otherwise be applicable,
but NBD could lawfully maintain the Eurodollar Rate Loans at the Floating Rate
then, during such period as NBD cannot maintain the Eurodollar Rate Loans at
the Adjusted Eurodollar Rate, the Eurodollar Rate Loans shall bear interest at
a per annum rate equal to the Floating Rate in effect from time to time.  If
all events or conditions making it unlawful or impossible for NBD to maintain
the Eurodollar Rate Loans at the Adjusted Eurodollar Rate cease to exist, then
the Eurodollar Rate Loans shall again bear interest at the Adjusted Eurodollar
Rate, commencing on the first day of the next Loan Period immediately following
the date all such events and conditions so cease to exist.





                                       25
<PAGE>   30


     4.8  Indemnity.  If the Borrowers fail to make any payment of principal or
interest in respect of any Fixed Rate Loan when due or makes any payment or
prepayment of the principal of any Fixed Rate Loan, for any reason, on any date
other than the last day of the Loan Period applicable thereto or, with respect
to any Negotiated Rate Loan, the maturity date thereof, or if the rate of
interest with respect to any Eurodollar Rate Loan shall be converted from the
Adjusted Eurodollar Rate, pursuant to Section 4.7(b), on a date other than the
last day of the Loan Period applicable thereto, or if the Borrowers fail to
borrow any Eurodollar Rate Loan after requesting the same in accordance with
this Agreement, the Borrowers shall reimburse NBD on demand for any resulting
loss or expense incurred by NBD, including any loss incurred in obtaining,
liquidating or employing deposits from third parties.  A statement as to the
amount of such loss or expense, prepared in good faith and in reasonable detail
and submitted by NBD to the Borrowers, shall be conclusive and binding for all
purposes absent manifest error in computation.  Calculation of all amounts
payable to NBD under this Section 4.8 with regard to Eurodollar Rate Loans
shall be made as though NBD shall have funded or committed to fund such through
the purchase of an underlying deposit in an amount equal to such Loans and
having a maturity comparable to such Loans through the London Branch; provided,
however, that NBD may fund the Rate Loans in any manner it sees fit and the
foregoing assumption shall be utilized only for the purpose of calculation of
amounts payable under this Section 4.8.

and during the continuance of any Event of Default, NBD shall by notice to
Borrowers terminate the Commitment or declare the outstanding principal of, and
accrued interest on, the Note and all other Obligations to be immediately due
and payable, or both, whereupon the Commitment shall terminate forthwith and
all such amounts shall become immediately due and payable, or both; provided,
however, that, in the case of any event or condition described in Section
7.1(i) 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 or any other
Loan Document or under applicable law, in any manner deemed appropriate by it,
including suit in equity, action at law, or other appropriate proceedings,
whether for the specific performance (to the extent permitted by law) of any
covenant or agreement contained in this Agreement or in any other Loan Document
or in aid of the exercise of any power granted in this Agreement 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
time to time, without notice to the Borrowers (any requirement for such notice
being expressly waived by the Borrowers) set off and apply against any and all
of the Obligations any and all deposits (general or special, time or demand,
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
not NBD shall have made any demand hereunder and although such obligations may
be contingent and unmatured.  The Borrowers hereby grant to NBD a Lien on all
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) are in addition to other rights and remedies (including other rights of
setoff) which NBD may otherwise have.

                         ARTICLE VIII CROSS-GUARANTIES

     8.   Cross Guaranties.

     8.1     Guaranty.  Each Borrower hereby unconditionally and absolutely
guarantees to  NBD the full and complete payment and performance when due of
the obligations of each of the other Borrowers to NBD, whether under this Loan
Agreement and the Notes, or otherwise.  The obligations of any Borrower to NBD
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.

<PAGE>   44

     8.3  Subrogation; Subordination.  No claim, including without limitation,
reimbursement, contribution, indemnity or subrogation, which any Borrower may
have against any other guarantor of any of the Guarantied Obligations or
against any other Borrower shall be enforced nor any payment accepted until the
Obligations are paid in full and all such payments are not subject to any right
of recovery.


                          ARTICLE IX.   MISCELLANEOUS

     9.1  Amendments.  No provision of this Agreement or any other Loan
Document may be modified, waived, or amended except by an instrument or
instruments signed by the Company and NBD.

          (a)   General.  Except as otherwise provided in Section 9.2(c), all

the "Address for Notices" set forth on the signature pages hereof; or to such
other address as may be designated by the Borrowers or NBD by written notice to

forth on the signature pages hereof or as may otherwise be designated in
accordance herewith.

          (b)   Notices of Termination or Prepayment.  Notices by the Borrowers
to NBD with respect to terminations or reductions of the Commitment or the L/C
Sublimit pursuant to Section 2.2, and notices of prepayment pursuant to Section
4.1 shall be irrevocable and binding on the Borrowers.

          (c)   Telephonic Notices.  Any notice to be given by the Borrowers to
NBD pursuant to Section 3.1, 3.2, 3.3 or 3.4 and any notice to be given by NBD
hereunder, may be given by telephone, to be confirmed in writing in the manner
provided in Section 9.2(a).  Any such notice given by telephone shall be deemed
effective upon receipt thereof by the party to whom such notice is given.

     9.3  No Waiver By Conduct; Remedies Cumulative.  No course of dealing on
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
NBD's rights and remedies hereunder or under any other Loan Document; nor shall
any single or partial exercise thereof preclude any further exercise thereof or
the exercise of any other right, power or privilege.  No right or remedy
conferred upon or





                                       40
<PAGE>   45

reserved to NBD under this Agreement or under any other Loan Document is
intended to be exclusive of any other right or remedy, and every right and
remedy shall be cumulative and in addition to every other right or 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
occurrence or continuance of any Default or Event of Default.

     9.4  Reliance on and Survival of Various Provisions.  All terms,
covenants, agreements, representations and warranties of the Borrowers made
herein or in any certificate, report, financial statement or other document
furnished by or on behalf of the Borrowers or the Guarantor in connection with
this Agreement or any other Loan Document shall be deemed to be material and to
have been relied upon by NBD, notwithstanding any investigation heretofore or
hereafter made by NBD, and those covenants and agreements of the Borrowers set
forth in Article IV and Section 9.5 shall survive the repayment in full of the
Obligations and the termination of this Agreement and the Commitments.

     9.5  Expenses; Indemnification.  The Borrowers agree, jointly and
severally, to pay, or reimburse NBD for the payment of, on demand, (a) the
reasonable fees and expenses of counsel to NBD, including the fees and expenses
of Honigman Miller Schwartz and Cohn in connection with the preparation,
execution, delivery and administration of this Agreement and the consummation
of the transactions contemplated hereby, and in connection with advising NBD as
to its rights and responsibilities with respect thereto, and in connection with
any amendments, waivers or consents in connection therewith, and (b) all stamp
and other taxes and fees payable or determined to be payable in connection with
the execution, delivery, filing or recording of this Agreement, the Note and
the other Loan Documents and the consummation of the transactions contemplated
hereby, and any and all liabilities with respect to or resulting from any delay
in paying or omitting to pay such taxes or fees, and (c) all reasonable costs
and expenses of NBD (including reasonable fees and expenses of counsel and
whether incurred through negotiations, legal proceedings or otherwise) in
connection with any Default or Event of Default or the enforcement of, or the
exercise or preservation of any rights under, this Agreement or any other Loan
Document or in connection with any refinancing or restructuring of the credit
arrangements provided under this Agreement.  The Borrowers, jointly and
severally, further agree to indemnify NBD for any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind and nature whatsoever (including
reasonable attorneys' fees) which may be imposed on, incurred by or asserted
against NBD in any way relating to or arising out of its duties under this
Agreement or any other Loan Documents or the transactions contemplated hereby
(excluding, unless a Default or an Event of Default has occurred and is
continuing, normal administrative costs and expenses incident to the
performance of its duties hereunder); provided, however, that the Borrowers
shall not be liable for any of the foregoing to the extent they arise from the

                                       41
<PAGE>   46

     9.6  Successors and Assigns.  This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns; provided, however, that the Borrowers may not, without the prior
consent of NBD, assign its rights or obligations hereunder or under the Note
and NBD shall not be obligated to make any Loan or issue any L/C or Guaranty
Issued by NBD hereunder to or for the account of any person other than the
Borrowers.

     9.7  Participations.  NBD may grant participations in all or any part of
its Loans, Note and Commitment to any bank or other institutional investor
(including any Affiliate of NBD), without the consent of the Borrowers.  The
Borrowers hereby acknowledge and agree that any participant described in this
Section 9.7 shall be considered to have the same rights and remedies as NBD
hereunder (including for purposes of Section 7.2(c)) and may rely on, and
possess all rights under, any opinions, certificates, or other instruments or
documents delivered under or in connection with this Agreement or any Loan
Document.

     9.8  Disclosure of Information.  The Borrowers authorize NBD to disclose
to any permitted participant or assignee of NBD or to any successor of NBD
(each, a "Transferee") and any prospective Transferee any and all financial and
other information in NBD's possession concerning the Borrowers which has been
delivered to NBD by the Borrowers pursuant to this Agreement or the other Loan
Documents or which has been received by NBD in connection with its credit
evaluation of the Borrowers prior to entering into this Agreement.

     9.9  Counterparts.  This Agreement may be executed in any number of
counterparts, all of which taken together shall constitute one and the same
instrument and any of the parties hereto may execute this Agreement by signing
any such counterpart.

     9.10 Governing Law.

          (a)   General.  This Agreement is a contract 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 such State and
without giving effect to choice of law principles of such State, except that
any Guaranty Issued by NBD hereunder shall be governed by and construed in
accordance with the laws of the United Kingdom.  The Company further agrees
that any legal action or proceeding with respect to this Agreement or any other
Loan Document or the transactions contemplated hereby may be brought in any
court of the State of Michigan, or in any court of the United States of America
sitting in the Eastern District of Michigan, or, with respect to Guaranties
Issued by NBD or Revolving Loans denominated in Pounds Sterling any court of
the United Kingdom sitting in or having jurisdiction over London; and the
Borrowers hereby submits to and accepts generally and unconditionally the
jurisdiction of those courts with respect to its person and property.

          (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





                                       42
<PAGE>   47

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 its property, such Borrower hereby irrevocably waives such immunity in
respect 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





                                       43
<PAGE>   48

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
LOAN DOCUMENTS OR ANY OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR ANY
COURSE OF CONDUCT, DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF
ANY OF THEM.  NEITHER NBD NOR THE ANY OF THE BORROWERS SHALL SEEK TO
CONSOLIDATE, BY COUNTERCLAIM OR OTHERWISE, ANY SUCH ACTION IN WHICH A JURY
TRIAL HAS BEEN WAIVED WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR
HAS NOT BEEN WAIVED.  THESE PROVISIONS SHALL NOT BE DEEMED TO HAVE BEEN
MODIFIED IN ANY RESPECT OR RELINQUISHED BY NBD OR THE BORROWERS EXCEPT BY A
WRITTEN INSTRUMENT EXECUTED BY ALL OF THEM.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed as of this 10th day of August, 1995, which shall be the date
inserted by NBD on which it has received counterparts of this Agreement

$8,000,000                                                     August  10, 1995
                                                               Detroit, Michigan

    FOR VALUE RECEIVED, the undersigned, MEDAR, INC. ("Medar"),  AUTOMATIC
INSPECTION DEVICES, INC. ("AID"), and INTEGRAL VISION, LTD.  ("Integral"),
jointly and severally (collectively, "Borrowers"), hereby promise to pay to the
order of NBD Bank, ("Bank"), pursuant to that Revolving Credit and Loan
Agreement, entered into as of August 10, 1995 (the "Loan Agreement"), among
Borrowers and Bank, at the main office of Bank in Detroit, Michigan with
respect to Revolving Loans made in U.S. Dollars, and at Bank's office in
London, England with respect to Revolving Loans made in Pounds Sterling, in
accordance with the Loan Agreement, in immediately available funds, the
principal sum of Eight Million and 00/100 Dollars (U.S. $8,000,000), or such
lesser amount as is recorded on the books and records of Bank, on August 10,
1997, 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.  All payments of
principal and interest shall be made (i) if the Revolving Loan is in Dollars
and advanced by Bank in the United States, then in lawful money of the United
States of America, and (ii) if the Revolving Loan is in Pounds Sterling and
advanced by Bank's London Branch, then in lawful money of the United Kingdom.

    Bank is hereby authorized by Borrowers to record on its books and records,
the date and amount of each Revolving Loan, the currency, 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.  Capitalized
terms used but not defined in this Note shall have the respective meanings
assigned to them in the Loan Agreement.

    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,
Borrower shall
<PAGE>   52

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 Amended and Restated Revolving Note amends and restates, but does not
satisfy, certain existing obligations of the Borrowers evidenced by the Master
Promissory Note in the principal amount of $5,000,000 dated June 13, 1994, from
Medar and AID to Bank (f/k/a NBD Bank, N.A.).

    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.

       AND THE UNDERSIGNED HEREBY AGREE(S) WITH THE BANK AS FOLLOWS:

       (1)    The Bank may grant time, renewals, extensions, indulgences,

the Bank from the customer or from others or from estates shall be regarded for
all purposes as payments in gross with out any rights on the part of the
undersigned to claim in reduction of the liability under this guarantee the
benefit of any such dividends, compositions, proceeds or payments or any
securities held by the Bank or proceeds thereof, and the undersigned shall have
no right to be subrogated in any rights of the Bank until the Bank shall have
received payment in full of the liabilities.

appropriation of any moneys received by it and to re-apply the same on any
other part or parts of the Liabilities as the Bank may see fit, notwithstanding
any previous application by whomsoever made.

       (10)   Without in any manner limiting the generality of the foregoing,
the undersigned agrees that the Bank may, from time to time, consent to any
action or non-action of the Customer which, in the absence of such consent,
violates or may violate any agreement or agreements between the Customer and
the Bank relating to any of the Liabilities, with or without consideration and
on such terms and conditions as may be acceptable to the Bank, without in any
manner affecting or impairing the liability of the undersigned hereunder.

       (11)   The undersigned shall at all times and from time to time do,
execute, acknowledge and deliver or cause to be done, executed, acknowledged
and delivered all and singular every such further act, deed, transfer,
assignment, assurance, document and instrument as the Bank may reasonably
require for the better accomplishing and effectuating of this guarantee and the
provisions contained herein, and every officer of the Bank and each of them
irrevocably appointed attorneys or attorney to execute in the name and on
behalf of the undersigned any document or instrument for the said purpose.

       (12)   All moneys, advances, renewals and credits in fact borrowed or
obtained from the Bank shall be deemed to form part of the Liabilities,

defect or informality in the borrowing or obtaining of such moneys, advances,

which may not be recoverable from the undersigned on the footing of a guarantee
shall be recoverable from the undersigned as sole or principal debtor in
respect thereof and shall be paid to the Bank on demand with interest and

other guarantee, by whomsoever given, at any time held by the Bank, and any
present or future obligation to the Bank incurred or arising otherwise than
under a guarantee, of the undersigned or any of them or of any other obligant,
whether bound with or apart from the Customer; excepting any guarantee
surrendered for cancellation on delivery of this instrument.

       (14)   The undersigned and each of them shall be bound by any account
settled between the Bank and the Customer, and if no such account has been so
settled immediately before demand for payment under this guarantee any account
stated by the Bank shall be accepted by the undersigned as conclusive evidence

to the Bank or remains unpaid by the Customer to the Bank.

<PAGE>   58

       (15)   This guarantee shall continue to be effective or be reinstated (as
the case may be) if at any time payment by the Customer or all or any part of
the Liabilities of the Customer to the Bank is rescinded or must otherwise be
returned by the Bank upon the insolvency, bankruptcy or reorganization of the
Customer or otherwise, all as if such payment to the Bank had not been made.

       (16)   This guarantee and agreement shall be operative and binding upon
every signatory thereof notwithstanding the non-execution thereof by any other
proposed signatory or signatories, and possession of this instrument by the
Bank shall be conclusive evidence against the undersigned that this instrument
was not delivered in escrow or pursuant to any agreement that it should not be
effective until any conditions precedent or subsequent had been complied with,
unless at the time of receipt of this instrument by the Bank each signatory
thereof obtains from the Manager of the branch or agency of the Bank receiving
this instrument a letter setting out the terms and conditions under which this
instrument was delivered and the conditions, if any, to be observed before it
becomes effective.

       (17)   a.     The undersigned agrees to make immediate payment to the
Bank of all Liabilities owing or payable to the Bank upon receipt of a demand
for payment therefor by the Bank to the undersigned in writing.  Each payment
to be made by the undersigned in respect of the Liabilities shall be payable in
the currency in which such Liabilities are denominated, and shall be made  --

              (i)    without set-off or counterclaim; and

              (ii)   free and clear of and without deduction or withholding for
                     or on account of any present or future taxes unless the
                     undersigned is compelled by law to make payment subject to
                     such taxes.

              b.     All taxes in respect of the Guaranty or any amounts
payable or paid under this Guarantee shall be paid by the undersigned when due
and in any event prior to the date on which penalties attach thereto.  The
undersigned will indemnify the Bank against and in respect of all such taxes.

                     Without limiting the generality of the foregoing, if any
taxes or amounts in respect thereof must be deducted or withheld from any
amounts payable or paid by the undersigned under this Guarantee, the
undersigned shall pay such additional amounts as may be necessary to ensure
that the Bank receives a net amount equal to the full amount which it would
have received had payment not been made subject to such taxes.  Within thirty
(30) days of each payment by the undersigned under this Guarantee of taxes or
in respect of taxes, the undersigned shall deliver to the Bank satisfactory
evidence (including originals, or certified copies, of all relevant receipts)
that such taxes have been duly remitted to the appropriate authority or
authorities.

       18.    If for the purposes of obtaining judgment in any court in any
jurisdiction with respect to this Guarantee, it becomes necessary to convert
into the currency of such jurisdiction (herein called the "Judgment Currency")
any amount due under this Guarantee in US currency, then conversion shall be
made at the rate of exchange prevailing on the business day before the day on
which judgment is given.  For this purpose, "rate of exchange" means the rate
at which the Bank would, on the relevant date, be prepared to sell a similar
amount of US currency in Detroit, Michigan, against the Judgment Currency.  In
the event that there is a change in the rate of exchange prevailing between the
business day before the day on which the judgment is given and the date of
payment of the amount due, the undersigned will, on the date of payment, pay

                                   LITIGATION



         Square D Company v Medar, Inc.  This matter involves litigation
against the Company in courts in Delaware and Michigan alleging patent
infringement.  This matter has been settled, however, final documentation is
still being negotiated.

         Potential Liability to Toyoda Machinery.  On September 2, 1988, the
assets of Medar's subsidiary, Industrial Development Systems, Inc., were sold
to Toyoda Machinery, USA, Inc.  As a part of that transaction, and pursuant to
an Indemnity Agreement which was executed between Toyoda and Medar, Medar is
responsible for the clean up of environmental damage existing on the former IDS
real estate up to the sum of $100,000.  It has been determined that there had
been a previous discharge of solvents into the ground on the property.
Subsequent events and documentation resulting from testing and environmental
audit indicate that there is good likelihood that there is a problem of
pollution.  Toyoda and its consultants are working with the Michigan Department
of Natural Resources to develop an acceptable plan for remediation.  Medar has
reimbursed Toyoda at the maximum amount required, $100,000.  The property has
been added to the "Act 307 List", a listing of environmental contamination
sites in Michigan.  Toyoda Machinery, USA, Inc. has notified prior owners of
the property of their potential liability for contribution toward clean up
costs; however, Medar has a contractual right to recover the first $100,000 in
contribution from these prior owners.  Toyoda has also now taken the position
that Medar is not entitled to the benefits of the indemnification but have
given no legal basis for this position.  On April 29, 1992, Medar entered into
an agreement with Maxco, Inc., the company from whom the property was acquired,
whereby Maxco, Inc. agreed to assume responsibility for all legal and expert
witness costs incurred in connection with the alleged contamination of the
property, on behalf of itself and Medar.  Maxco further agreed not to hold
Medar liable for any amounts for which Maxco may be found to be liable because
of the contamination, while Medar agreed not to seek or accept reimbursement
from Maxco for the $100,000 which Medar has been required to pay to Toyoda.  In
our detailed review of the matter, we are of the opinion that the damage done
to the ground was probably done before Medar had any involvement of the
property.  If this can be proved, Medar should not have any additional
liability for the damage.

         Potential liability to CDA Associates, Inc.
                                                   

         This matter involves a claim for payment arising from a license
agreement between Medar and CDA Associates, Inc. ("CDA")  CDA manufactures and
sells certain lines of disc analyzers, and granted a license to Medar to sell
CDA's products.  By letter dated April 25, 1995, CDA claims $301,631.61 is due
and owing for its products sold to Medar and its subsidiary, Automatic
Inspection Devices, Inc. ("AID").  Medar and AID claim offsets, credits, and
monies owed by CDA of over approximately  $496,000.00, arising from defective
products, unfilled orders, late deliveries, unpaid commissions, and the failure
of CDA to honor servicing and upgrading of equipment.   To date, no litigation
has been started, and Medar and AID have, and intend to vigorously defend the
claim of CDA.  Both sides have been responding to the respective claims by
letter and it is anticipated that the matter will be resolved short of
litigation.

           AMENDMENT NO. 2 TO LOAN AND CREDIT AGREEMENT AND TERM NOTE


       This Amendment is made as of August 10, 1995, to the Loan and Credit
Agreement dated June 29, 1993, as amended by Amendment No. 1 to Loan and Credit
Agreement dated June 13, 1994 (as amended, the "Agreement"), among Medar, Inc.,
a Michigan corporation ("Medar"), Automatic Inspection Devices, Inc., an Ohio
corporation ("Automatic") and NBD Bank (successor to NBD Bank, N.A.), a
Michigan banking corporation (the "Bank").  This Amendment also amends the Term
Note dated June 29, 1993 ("Term Note") from Medar to the Bank in the original
principal amount of $2,500,000.


                                    RECITALS

       A.     The Bank has agreed to extend a revolving credit facility to
Medar, Automatic and Intergral Vision Ltd. pursuant to a Revolving Credit and
Loan Agreement being executed simultaneously herewith ("Revolving Credit
Agreement").  Such revolving credit facility replaces the prior authorizations
given to Medar and Automatic.

       B.     The Bank has also agreed to extend an equipment loan facility to
Medar and Automatic pursuant to the terms of the Revolving Credit Agreement.

       C.     Medar, Automatic and the Bank have agreed to amend the Agreement
to conform certain covenants of the parties to the Revolving Credit Agreement
and to amend the interest rate under the Term Note.

       THEREFORE, the parties agree as follows:

              1.     All capitalized terms not otherwise defined herein shall
                     have the meanings given to them in the Agreement.

              2.     The Term Note evidencing the indebtedness of Medar under
Facility A is hereby amended to delete the clause "of one fourth of one percent
(1/4%) per annum more than the rate" from the first paragraph of the Term Note
so that effective May 12, 1995, the Note Rate as defined in the Term Note will
be the Bank's prime rate as announced from time to time.

              3.     Facility D is terminated.

              4.     Sections 5.3(A), (B) and (C) are hereby deleted in their
entirety and replaced with the following:

       (A)    The Borrowers shall not violate Sections 6.2(a) or (b) of the
       Revolving Credit Agreement, as the same may be amended from time to
       time; or in the event that the Revolving Credit Agreement is restated or
       replaced by another agreement which provides a revolving credit facility
       to Medar or any of its affiliates, the Borrowers shall not violate any
       financial covenant in such replacement or restated
<PAGE>   2

       agreement; or in the event that there ceases to be any agreement between
       NBD and Medar or its affiliates for a revolving credit facility, the
       Borrowers shall not violate the financial covenants which were
       established by NBD in its agreement that was executed latest in time
       with Medar that provided for a revolving credit facility, regardless of
       the termination of such facility.

              5.     Except as expressly modified by this Amendment, the terms
of the Agreement and the Term Note are hereby ratified and confirmed and remain
in full force and effect.

              6.     In the event of an express conflict between the terms of
this Amendment and the Agreement or the Term Note, the terms of this Amendment
will govern and control.

       IN WITNESS WHEREOF, the parties have executed this Amendment as of the
10th day of August, 1995.
