                    NOTES TO  CONSOLIDATED FINANCIAL STATEMENTS


NOTE A - BASIS OF PRESENTATION

The interim consolidated financial statements of Interface Systems, Inc.
have been prepared by the Company without audit pursuant to the rules and
regulations of the Securities and Exchange Commission.  Certain information
and footnote disclosures normally included in financial statements prepared
in accordance with generally accepted accounting principles have been
condensed or omitted pursuant to such rules and regulations.  The
information included in this report should be read in conjunction with the
financial statements for the year ended September 30, 1996 and notes thereto
included in the Company's Annual Report on Form 10-K.

In the opinion of management, the accompanying interim consolidated
financial statements reflect all adjustments (consisting only of normal
recurring adjustments) necessary for a fair presentation of the Company's
financial position, results of operations and cash flows for the periods
presented.  The results for the quarter ended March 31, 1997 are not
necessarily indicative of the results to be expected for any future period
or for the entire year.

NOTE B - BORROWINGS

On February 19, 1997, the Company renewed its credit facilities with a bank
which provide for aggregate borrowings of up to $11.5 million.  As of March 
31, 1997,  $8,346,939 was outstanding under these facilities.  Advances
under these facilities bear interest at the bank's prime rate (8.5% at March
31, 1997) plus 1/2%, are payable on demand and are collateralized by
substantially all of the Company's assets.  The credit facilities expire
August 31, 1997 and are subject to renewal thereafter.

Under the terms of the agreements, the Company is required to maintain
certain minimum working capital, net worth and profitability levels and
other specific financial ratios.  In addition, the agreements prohibit the
payment of cash dividends and contain certain restrictions on the Company's
ability to borrow money or purchase assets or interests in other entities
without the prior written consent of the bank.

NOTE C - TREASURY SHARES TO BE ACQUIRED

During the quarter, the Company acquired 127,495 shares of its Common Stock
valued at $637,476, upon the default in payment of all principal and
interest due and owing as of such date by a former officer of the Company
under the terms of a note payable owed by such officer to the Company.  The
value of the shares is equal to all indebtedness which was owed to the
Company at the time of default.

Item 2.   Management's Discussion and Analysis of Financial Condition and 
Results of Operations Results of Operations

Net Revenues.

Revenues for the second quarter ended March 31, 1997 were $23.3 million, an
increase of 6.5% over revenues of $21.9 million for the second quarter of
fiscal 1996.  Revenues for the first six months of fiscal 1997 were $42.9
million, an increase of 5.7% over revenues of $40.6 million for the same
period of fiscal 1996.  The increases for both the quarter and six month
periods were primarily due to increased distribution revenue of  Interface
Systems International Ltd. ("ISIL") and increased sales of Enterprise
Network core products, offset by a decrease in sales of printer products.  

Cost of Revenues.   Cost of revenues increased to $21.4 million, or 92% of
net revenues for the second quarter ended March 31, 1997, from $18.4
million, or 84% of net revenues for the second quarter of fiscal 1996. Cost
of revenues increased to $38.4 million, or 90% of net revenues for the first
six months of fiscal 1997, from $33.8 million, or 83% of net revenues for
the same period of fiscal 1996.  For the second quarter and the first six
months of fiscal 1997, cost of revenues increased in absolute dollars and as
a percentage of net revenue primarily due to write-offs related to the
printer business consisting of $1,445,000 of inventory and $320,000 of
software development costs.  The write-offs reflect obsolescence and pricing
pressures in the rapidly changing printer market and the Company's shift
towards greater emphasis on software products.  Cost of revenues for the
second quarter and the first six months of fiscal 1997, excluding the effect
of the write-offs, was 84% and 85% of sales, respectively.  In addition, the
increase in cost of revenues results from increased ISIL distribution
revenue which has higher component cost and lower gross profit margins.

Product Development Costs.   Product development costs increased 45% to
$626,000 for the second quarter of fiscal 1997 from $431,000 for the second
quarter of fiscal 1996.  Product development costs increased 30% to
$1,128,000 for the first six months of fiscal 1997 from $868,000 for the
same period of fiscal 1996.  The increase for both periods primarily
reflects a change in the Company's strategy towards greater emphasis on
developing software products, which resulted in a decrease in the amount of
expense deferred through capitalization of internally developed software.

Selling, General and Administrative Expenses.    Selling, general and
administrative expenses increased 27% to $3.2 million for the second quarter
of fiscal 1997 from $2.5 million for the second quarter of fiscal 1996. 
Selling, general and administrative expenses increased 25% to $6.2 million
for the first six months of fiscal 1997 from $4.9 million for the same
period of fiscal 1996.  The increase in these expenses is due to increased
selling and marketing personnel in the United Kingdom to support the growth
in ISIL's distribution business and to expenses associated with an interim
management team and the hiring of a new CEO.  In addition, the increase for
the first six months of fiscal 1997 is due to marketing expenses incurred to 
promote the Company's Oasis products.

Interest Expense.   For the second quarter of fiscal 1997, interest expense
increased to $158,000 from $115,000 for the same period of 1996.  For the
first six months of fiscal 1997, interest expense increased to $315,000 from
$218,000 for the same period of 1996.  The increases were due to increased
borrowing, primarily at ISIL. 

Income Taxes.   The effective tax rate for the quarter and six months ended
March 31, 1997 was a benefit of 28.9% and 26.5%, respectively.  The tax
benefit for these periods was below the statutory rate because losses at
ISIL are not eligible for tax benefit.

Liquidity and Capital Resources

At March 31, 1997, the Company's primary sources of liquidity included cash
and cash equivalents of $711,000 and short-term credit facilities with a
bank providing for $11.5 million of borrowings, of which $3.2 million was
available.

<PAGE>

For the first six months of fiscal 1997, net cash of $2.5 million was used
in operating activities compared to net cash of $1.3 million provided by
operating activities for the same period of fiscal 1996.  Cash was used in
operating activities for the first six months of fiscal 1997 primarily as a
result of net operating losses for the period and increased accounts
receivable partially offset by increased accounts payable.  Net cash used in
investing activities was $1.2 million for the first six months of fiscal
1997 compared with $2.6 million for the same period of fiscal 1996.  The
decrease was primarily due to a $735,000 note receivable funded in the first
half of fiscal 1996, partially offset by proceeds from sale of securities of 
$177,000 in the first half of fiscal 1997.  In addition, the decrease was
due to reduction in additions to fixed assets and software development costs
in the first six months of fiscal 1997.

In February 1997, the Company renewed its credit facilities with a bank
which provide for aggregate borrowings of up to $11.5 million.  As of March 
31, 1997,  $8.3 million was outstanding under these facilities.  The
borrowings are used primarily by ISIL in the operation of its distribution
business.  Advances under these facilities bear interest at prime plus 1/2%
are payable on demand and are collateralized by accounts receivable,
inventory and machinery and equipment.  The credit facilities expire August 
31, 1997 and are subject to renewal thereafter.  Under the terms of the
agreements, the Company is required to maintain certain minimum working
capital, net worth and profitability levels and other specific financial
ratios.  In addition, the agreements prohibit the payment of cash dividends
and contain certain restrictions on the Company's ability to borrow money or
purchase assets or interests in other entities without the prior written
consent of the bank. 

The Company believes that its existing cash balances, available credit
facility and future operating cash flows are sufficient for near term
operating needs.  The Company believes it will renew the bank credit
facilities prior to expiration of the facilities.

                part thereof, the Bank may open a new account for the
                Company.  If it does not do so then, unless the Bank gives
                express written notice to the contrary to the Company, it
                shall nevertheless be treated as if it had opened a new
                account at the time when it received such notice and as from
                that time all payments made by or on behalf of the Company to
                the Bank shall be credited or be treated as having been
                credited to the new account and shall not operate to reduce

                options on such terms as the Bank shall consider expedient
                and without the need to observe any of the provisions of
                sections 99 and 100 Law of Property Act 1925 (or In the case
                of property in Northern Ireland section 18 of the
                Conveyancing and Law of Property Act 1881).

                by this Deed at a time when no amount In respect of the
                Secured Obligations is due and payable, the Bank (or the
                Receiver) may pay the proceeds of any recoveries effected by
                it into an interest-bearing suspense account.  The Bank may
                (subject to the payment of any claims having priority to this

                suspense account for application as follows:

                (a)         paying all costs, charges and expenses incurred
                            and payments made by the Bank (or the Receiver) in

                            the same becomes due and payable; and

                (c)         paying amounts due and payable in respect of the
                            Secured Obligations as and when the same become

not been waived.  These provisions shall not be deemed to have been modified
in any respect or relinquished by either the Bank or the Borrower except by

and persons to which they apply on their effective dates, including
contingent liabilities of every type, which financial condition has not
changed materially and adversely since those dates.  Each Borrower, other
than a natural person, further represents:  (a) that it is duly organized,
existing and in good standing pursuant to the laws under which it is
organized; and (b) that the execution and delivery of this note and the
performance of the obligations it imposes (i) are within its powers and have
been duly authorized by all necessary action of its governing body; and (ii)

governing its affairs.

had the opportunity to consult with counsel, knowingly, voluntarily and
intentionally waive any right either of them may have to a trial by jury in
any litigation based upon or arising out of this note or any related
instrument or agreement or any of the transactions contemplated by this note
or any course of conduct, dealing, statements whether oral or written, or
actions of either of them.  Neither the Bank nor the Borrower shall seek to
consolidate, by counterclaim or otherwise, any 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 either the Bank or the Borrower except by
a written instrument executed by both of them.

                            CONTINUING PLEDGE AGREEMENT


                PLEDGE:  To induce NBD Bank, of 611 Woodward Avenue, Detroit,
Michigan 48226-3497 (the "Bank"), at its option, to make loans, extend or
continue credit or some other benefit, including guaranties, letters of
credit and foreign exchange contracts, present or future, direct or
indirect, and whether several, joint or joint and several (referred to
collectively as "Liabilities"), to the undersigned and its successors (the
"Pledgor"), and

(check if applicable)

[ ]             to Interface Systems, Inc. and its successors (the
"Borrower"), and because the Pledgor has determined that executing this
Pledge is in its interest and to its financial benefit, the Pledgor pledges
and transfers to the Bank, and grants the Bank a continuing security
interest in the property listed below under the heading "Schedule of
Collateral."  If the Collateral consists of securities, the grant includes
any stock rights, stock dividends, liquidating dividends, new securities and
other property to which the Pledgor may become entitled because it owns the
Collateral.  The Pledgor has transferred the securities to the Bank.  In the
event the transfer is not complete, the Pledgor will complete it within 10
days.  This security interest shall secure all Liabilities and includes
principal, interest, expenses, reasonable attorneys' fees, and all other
costs of collection.  The Pledgor agrees to hold the Bank harmless from any
liability caused by its reliance on this Pledge.

SCHEDULE OF COLLATERAL:

1,400,000 shares Interface Systems, International, Ltd., Certificate #15
including substitutions, replacements, additions and proceeds.  Any
securities or other property of the Pledgor at any time in the custody,
possession or control of the Bank shall also constitute Collateral, unless
the Bank holds such property solely in a fiduciary capacity.

WARRANTIES AND COVENANTS:  The Pledgor warrants it owns the Collateral free
and clear of any liens.  The Pledgor will not attempt to sell or assign the
Collateral or create any lien or claim against it.  The Pledgor agrees to
reimburse the Bank, on demand, for any amounts paid or advanced by the Bank
for the purpose of preserving all or any part of the Collateral.  The Bank
shall exercise reasonable care in the custody and preservation of the
Collateral to the extent required by applicable statute.  The Bank shall use
its best efforts to take any action the Pledgor may reasonably request in
writing, but the failure to do so shall not be deemed a failure to exercise
reasonable care.

REGISTRATION RIGHTS:  If any of the Collateral consists of securities not
registered under the Securities Act of 1933, and the issuer proposes to
register any of its securities, the Pledgor will give the Bank notice of
that fact.  In addition, and at no cost to the Bank, the Pledgor will use
its best effort to induce the issuer to register the pledged securities so
that they may be disposed of by public sale or other public disposition. 
Upon the completion of registration, the Pledgor will deliver certificates
without any restrictive legend in exchange for the unregistered securities. 
The Pledgor indemnifies and holds the Bank harmless against any loss, claim,
damage or liability arising out of the registration process, and will
reimburse the Bank for any legal or other expenses incurred by the Bank as a
result.

INSTRUCTIONS REGARDING THE COLLATERAL:  The Bank may act upon any
instructions given by the Pledgor whether in writing or not, with regard to
additions or substitutions or sale or other disposition of the Collateral
and its proceeds.  The Pledgor agrees that any additions to, substitutions
for or proceeds of the Collateral that it or the Borrower receives will be
held for the Bank's benefit and turned over to the Bank.  The Pledgor also
gives the Bank permission to have the Collateral or any part of it
transferred to or registered in the Bank's name or in the name of any other
person, firm or corporation, with or without designation of the capacity of
such nominee, and will hold the Bank harmless from any liability or
responsibility that might result.  In furtherance of the Bank's rights under
this Pledge, the Pledgor irrevocably appoints the Bank as its attorney-in-
fact, with full power of substitution.

CONTINUED RELIANCE:  The Bank may continue to make loans or extend credit to
the Borrower based on this Pledge until it receives written notice of
termination from the Pledgor.  That notice shall be effective at the opening
of the Bank for business on the day after receipt of the notice.  The
termination will not affect any of the rights given to the Bank in this
Pledge with respect to any of the Liabilities that were created, assumed or
committed to prior to the Bank's receipt of the notice, and all subsequent
renewals, extensions, modifications and amendments of the Liabilities.  Upon
receipt of the notice, the Bank does not have to take any action against the
Borrower or the Collateral in order to maintain its rights.  If the Pledgor
is the Borrower, this Pledge is not terminable.

LOAN-TO-VALUE RATIO:  If the unpaid balance of the Liabilities shall at any
time exceed an amount equal to -------% of the then fair market value (as
reasonably determined by the Bank) of any securities constituting all or a
portion of the Collateral, and such excess continues for five (5) days after
notice from the Bank to the Pledgor, the Pledgor shall be in default under
this Pledge and the Bank may sell all or any portion of such securities and
otherwise exercise any or all of the rights and remedies set forth in this
Pledge.

DEFAULT/REMEDIES:  If the Pledgor or the Borrower fails to pay any of the
Liabilities when due, or if a default exists under the terms of any
agreement related to any of the Liabilities, or if the Pledgor dies or fails
to observe or perform any term of this Pledge, or if any representation or
warranty of the Pledgor contained in this Pledge is untrue in any material
respect, or if there is a material change in the financial condition of the
Pledgor which the Bank in good faith determines to be materially adverse,
then the Bank shall have all of the rights and remedies provided by any law
to liquidate or foreclose on and sell the Collateral, including but not
limited to the rights and remedies of a secured party under the Uniform
Commercial Code.  The Pledgor agrees and acknowledges that because of
applicable securities laws, the Bank may not be able to effect a public sale
of the Collateral, and sales at a private sale may be on terms and at a
price less favorable than if the securities were sold at a public sale.  The
Pledgor agrees that all private sales made under these circumstances shall
be deemed to have been made in a commercially reasonable manner.  These
rights and remedies shall be cumulative and not exclusive.  If the Pledgor
is entitled to notice, that requirement will be met if the Bank sends notice
at least seven (7) days prior to the date of sale, disposition or other
event requiring notice.  The proceeds of any sale shall be applied first to
costs, then toward payment of the Liabilities, whether or not the
Liabilities have been declared to be due and owing; provided that, to the
extent any Liabilities consist of extensions of credit to the Borrower by
the issuance of letters of credit or other like obligations of the Bank to
third parties which have not been utilized, such proceeds shall be held by
the Bank in a cash collateral account as security for the Liabilities.

WAIVERS:  The Pledgor waives any right it may have to receive notice of any
of the following matters before the Bank enforces any of its rights:  (a)
the Bank's acceptance of this Pledge, (b) any credit that the Bank extends
to the Borrower, (c) the Borrower's default, (d) any demand, or (e) any
action that the Bank takes regarding the Borrower, anyone else, any
collateral, or any Liability, which it might be entitled to take by law or
under any other agreement.  No modification or waiver of this Pledge shall
be effective unless it is in writing and signed by the party against whom it
is being enforced.  The Bank may waive or delay enforcing any of its rights
without losing them.  Any waiver shall affect only the specific terms and
time period stated in the waiver.  The Bank shall not be obligated to take
any action in connection with any conversion, call, redemption, retirement
or any other event relating to any of the Collateral.

WAIVER OF SUBROGATION:  Until thirteen months after the principal balance of
and interest on the Liabilities, even if not covered by this Pledge, shall
have been paid in full and the Borrower shall have fully performed all of
its obligations to the Bank, the Pledgor expressly waives any and all rights
of subrogation, contribution, reimbursement, indemnity, exoneration, implied
contract, recourse to security or any other claim (including any claim, as
that term is defined in the federal Bankruptcy Code, and any amendments)
which the Pledgor may now have or later acquire against the Borrower, any
other entity directly or contingently liable for the Liabilities, or against
the Collateral arising from the existence or performance of the Pledgor's
obligations under this Pledge.

The Pledgor further agrees that such waiver is permanent and shall not be
revoked or terminated, in any event, including payment in full of the
principal balance of and interest on the Liabilities in the event that
proceedings are commenced at any time after execution of this Pledge by or
against the Borrower under any bankruptcy, reorganization, liquidation or
similar laws of any jurisdiction, including the federal Bankruptcy Code. 
The Pledgor further agrees that should any payments to the Bank on the
Liabilities be in whole or in part invalidated, declared to be fraudulent or
preferential, set aside or required to be repaid to a trustee, receiver or
any other party under any bankruptcy act or code, state or federal law,
common law or equitable doctrine, this Pledge and any Collateral shall
remain in full force and effect (or be reinstated as the case may be) until
payment in full of any such amounts, which payment shall be due on demand.

REPRESENTATIONS BY PLEDGOR:  Each Pledgor represents: (a) that the execution
and delivery of this Pledge and the performance of the obligations it
imposes do not violate any law, conflict with any agreement by which it is
bound, or require the consent or approval of any governmental authority or
any third party; (b) that this Pledge is a valid and binding agreement,
enforceable according to its terms; and (c) that all balance sheets, profit
and loss statements, and other financial statements furnished to the Bank
are accurate and fairly reflect the financial condition of the organizations
and persons to which they apply on their effective dates, including
contingent liabilities of every type, which financial condition has not
changed materially and adversely since those dates.  Each Pledgor, other
than a natural person, further represents: (a) that it is duly organized,
existing and in good standing pursuant to the laws under which it is
organized; and (b) that the execution and delivery of this Pledge and the
performance of the obligations it imposes (i) are within its powers and have
been duly authorized by all necessary action of its governing body; and (ii)
do not contravene the terms of its articles of incorporation or
organization, its by-laws, or any partnership, oeprating or other agreement
governing its affairs.

NOTICES:  Notice from one party to another relating to this Pledge shall be
deemed effective if made in writing (including telecommunications) and
delivered to the recipient's address, telex number or facsimile number set
forth under its name by any of the following means: (a) hand delivery, (b)
registered or certified mail postage prepaid, (d) Federal Express, Purolator
Courier or like overnight courier service, or (e) telecopy, facsimile or
other wire transmission with request for assurance of receipt in a manner
typical with respect to communications of that type.  Notice made in
accordance with this section shall be deemed delivered on receipt if
delivered by hand or wire transmission, on the third business day after
mailing if mailed by first class, registered or certified mail or on the
next business day after mailing or deposit with an overnight courier service
if delivered by express mail or overnight courier.   Notwithstanding the
foregoing, notice of termination of this Pledge shall be deemed received
only upon the receipt of actual written notice by the Bank in accordance
with the paragraph above labeled "Continued Reliance."

MISCELLANEOUS:  The Pledgor consents to (a) any extension, postponement,
renewal, modification and amendment of any Liability, (b) the release or
discharge of all or any part of any security for the Liabilities, and (c)
the release or discharge or suspension of any rights and remedies against
any person who may be liable for the Liabilities.  The Bank does not have to
look to any other right, any other collateral or any other person for
payment before it exercises its rights under this Pledge.  The Pledgor's
obligations to the Bank under this Pledge are not subject to any condition,
precedent or subsequent, and shall not be released or affected by any change
in the composition or structure of the Borrower or Pledgor, including a
merger or consolidation with any other person or entity.  If this Pledge is
signed by more than one person, all shall be jointly and severally bound. 
This Pledge is binding on the Pledgor and its heirs, successors and assigns,
and is for the benefit of the Bank and its successors and assigns.  This
Agreement is governed by Michigan law.  The use of section headings shall
not limit the provisions of this Pledge.

WAIVER OF JURY TRIAL:  The Bank and the Pledgor, after consulting or having
had the opportunity to consult with counsel, knowingly, voluntarily and
intentionally waive any right either of them may have to a trial by jury in
any litigation based upon or arising out of this Pledge or any related
instrument or agreement, or any of the transactions contemplated by this
Pledge, or any course of conduct, dealing, statement (whether oral or
written), or actions of either of them.  Neither the Bank nor the Pledgor
shall seek to consolidate, by counterclaim or otherwise, any 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 either the Bank or the
Pledgor except by a written instrument executed by both of them.

of money and is of a type which is, in the ordinary course of business,
transferred by delivery alone or by delivery with any necessary endorsement
or assignment.

                5.          "Farm Products" shall consist of all poultry and
livestock and their young, along with their products and produce; all crops,
annual or perennial, and all products of the crops; and all feed, seed,
fertilizer, medicines, and other supplies used or produced in farming
operations.  The Debtor will provide the Bank with a written list of the
buyers, commission merchants or selling agents to or through whom it may
sell the Farm Products, in form acceptable to the Bank.  The Debtor will
keep this list current by notice to the Bank at least seven (7) days prior
to any sale.  In this paragraph the terms farm products, buyers, commission
merchants and selling agents have the meanings given to them in the Federal
Food Security Act of 1985, and Section 9307 of the UCC.

                6.          "Specific" shall consist of the following, and all
accessions, parts, attachments, accessories, additions, substitutions,
replacements, appurtenances and their related rights:   --------------------

ADDITIONAL TERMS AND CONDITIONS:  The Debtor agrees to all of the Terms and
Conditions on the reverse.

WAIVER OF JURY TRIAL:  The Bank and the Debtor after consulting or having
had the opportunity to consult with counsel, knowingly, voluntarily and
intentionally waive any right either of them may have to a trial by jury in
any litigation based upon or arising out of this agreement or any related
instrument or agreement, or any of the transactions contemplated by this
agreement, or any course of conduct, dealing, statements (whether oral or
written), or actions of either of them.  Neither the Bank nor the Debtor
shall seek to consolidate, by counterclaim or otherwise, any 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 either the Bank or the
Debtor except by a written instrument executed by both of them.

all extensions, renewals, modifications and replacements; and

(iv) Future Advances and Cross-Lien:  All other present and future, direct
and indirect obligations and liabilities of the Mortgagor, or any one or
more of them, with or without others, however evidenced, to the Mortgagee,
and all future advances, whether obligatory or optional, from the Mortgagee
to the Mortgagor, or any one or more of them, with or without others.  (This
shall not apply to any obligation or debt incurred for personal, family or
household purposes unless the note or guaranty expressly states that it is
secured by this Mortgage.)  Notwithstanding the foregoing, if this Mortgage
is a residential future advance mortgage, as defined in MCL 565.901, the
maximum principal amount secured by this Mortgage is $----------, excluding
protective advances as defined in MCL 565.901.

This Mortgage shall also secure the performance of the promises and
agreements contained in this Mortgage.

The Mortgagor promises and agrees as follows:

    1.       PAYMENT OF DEBT; PERFORMANCE OF OBLIGATIONS.  The Mortgagor shall
promptly pay when due, whether by acceleration or otherwise, the Debt for
which the Mortgagor is liable, and shall promptly perform all obligations to
which the Mortgagor has agreed under the terms of this Mortgage and any loan
documents evidencing the Debt.

    2.       TAXES.  The Mortgagor shall pay, when due, and before any
interest, collection fees or penalties shall accrue, all taxes, assessments,
fines, impositions, and other charges which may become a lien prior to this
Mortgage.  Should the Mortgagor fail to make such payments, the Mortgagee
may, at its option and at the expense of the Mortgagor, pay the amounts due
for the account of the Mortgagor.  Upon the request of the Mortgagee, the
Mortgagor shall immediately furnish to the Mortgagee all notices of amounts
due and receipts evidencing payment.  The Mortgagor shall promptly notify
the Mortgagee of any lien on all or any part of the Premises and shall
promptly discharge any unpermitted lien or encumbrance.

    3.       CHANGE IN TAXES.  In the event of the passage of any law or
regulation, state, federal or municipal, subsequent to the date of this
Mortgage in any manner changing or modifying the laws now in force governing
the taxation of mortgages or debts secured by mortgages, or the manner of
collecting such taxes, the Debt shall become due and payable immediately at
the option of the Mortgagee.

    4.       INSURANCE.  Until the debt is fully paid the Mortgagor shall keep
the Premises and the present and future buildings and other improvements on
the Premises, constantly insured for the benefit of the Mortgagee, without
any reduction in coverage based on the Mortgagor's acts, against fire and
such other hazards and risks customarily covered by the standard form of
extended coverage endorsement available in the State of Michigan, including
risks of vandalism and malicious mischief, and shall further provide flood
insurance if the Premises are situated in an area designated as a flood risk
area by the Director of the Federal Emergency Management Agency or as
otherwise required by the Flood Disaster Protection Act of 1973 and
regulations issued under it), and such other appropriate insurance as the
Mortgagee may require from time to time.  All insurance policies and
renewals must be acceptable to Mortgagee, must provide for payment to the
Mortgagee in the event of loss, must require thirty (30) days notice to the
Mortgagee in the event of nonrenewal or cancellation, and must be delivered
to the Mortgagee.  Should the Mortgagor fail to insure or fail to pay the
premiums on any insurance or fail to deliver the policies or certificates or
renewals to the Mortgagee then the Mortgagee at its option may have the
insurance written or renewed and pay the premiums for the account of the
Mortgagor.  In the event of loss or damage, the proceeds of the insurance
shall be paid to the Mortgagee alone.  No loss or damage shall itself reduce
the Debt.  The Mortgagee is authorized to adjust and compromise a loss
without the consent of the Mortgagor, to collect, receive and receipt for
any proceeds in the name of the Mortgagee and the Mortgagor and to endorse
the Mortgagor's name upon any check in payment of proceeds.  The proceeds
shall be applied first toward reimbursement of all costs and expenses of the
Mortgagee in collecting the proceeds and then toward payment of the Debt or
any portion of it, whether or not then due or payable, or the Mortgagee at
its option may apply the proceeds, or any part to the repair or rebuilding
of the Premises provided that Mortgagor is not then or at any time during
the course of restoration of the Premises in default under this Mortgage and
has complied with all requirements for application of the proceeds to
restoration of the Premises as Mortgagee, in its sole discretion may
establish.

    5.       RESERVES FOR TAXES AND INSURANCE.  The Mortgagor shall, if
requested by the Mortgagee, pay to the Mortgagee, at the time of and in
addition to the scheduled installments of principal or interest due under
the Debt, a sum equal to (a) the amount estimated by the Mortgagee to be
sufficient to enable it to pay, at least thirty (30) days before they become
due and payable, all taxes, assessments and other similar charges levied
against the Premises, plus (b) the amount of the annual premiums on any
policies of insurance required to be carried by the Mortgagor divided by (c)
the number of installments due each year.  These sums may be commingled with
the general funds of the Mortgagee, and no interest shall be payable on them
nor shall these sums be deemed to be held in trust for the benefit of the
Mortgagor.  Upon notice at any time, the Mortgagor will, within ten (10)
days, deposit such additional sum as may be required for the payment of
increased taxes, assessments, charges or premiums.

    Notwithstanding payment of any sums by the Mortgagor to the Mortgagee
under the terms of this paragraph, the Mortgagee shall have no obligation to
pay any taxes, assessments, premiums, or other similar charges relating to
or levied against the Premises.  The obligation of the Mortgagor to pay
taxes, assessments, charges, and insurance premiums is not affected or
modified by the arrangements set out in this paragraph.  Payment by the
Mortgagee on any one or more occasions of all or any portion of the taxes,
assessments, premiums, or other similar charges relating to or levied
against the Premises shall not be construed as obligating the Mortgagee to
pay any taxes, assessments, premiums, or other similar charges on any other
occasion.  If the Mortgagee elects to pay any taxes, assessments, or other
similar charges, it shall not be required to do so at any time prior to the
date on which penalties, interest, and/or collection fees begin to accrue. 
If the Mortgagee elects to pay any premium on any policy of insurance
required to be carried by the Mortgagor, it may do so at any time prior to
cancellation of the policy.

    In the event of foreclosure of this Mortgage, any of the moneys then
remaining on deposit with the Mortgagee or its agent shall be applied
against the Debt prior to the commencement of foreclosure proceedings.   The
obligation of the Mortgagor to pay taxes, assessments, charges or insurance
premiums is not affected or modified by the arrangements set out in this
section. Any default by the Mortgagor in the performance of the provisions
of this section shall constitute a default under this Mortgage.  The
Mortgagee shall not request the reserves provided for in this section as
long as there is no default by the Mortgagor under this Mortgage and the
Mortgagor retains title to the Premises.

    6.       WASTE.  The Mortgagor shall keep the Premises in good repair,
shall not commit or permit waste on the Premises nor do any other act
causing the Premises to become less valuable.  Non-payment of taxes and
cancellation of insurance shall each constitute waste as provided by MCL
600.2927.  The Mortgagor consents to the appointment of a receiver under
this statute should the Mortgagee elect to seek such relief.  Should the
Mortgagor fail to effect any necessary repairs, the Mortgagee may at its
option and at the expense of the Mortgagor make the repairs for the account
of the Mortgagor.  The Mortgagor shall use and maintain the Premises in
conformance with all applicable laws, ordinances and regulations.  The
Mortgagee or its authorized agent shall have the right to enter upon and
inspect the Premises at all reasonable times.

    7.       ALTERATIONS, REMOVAL.  No building, structure, improvement,
fixture or personal property constituting any part of the Premises shall be
removed, demolished or substantially altered without the prior written
consent of the Mortgagee.

    8.       PAYMENT OF OTHER OBLIGATIONS.  The Mortgagor shall also pay all
other obligations which may become liens or charges against the Premises for
any present or future repairs or improvements made on the Premises, or for
any other goods, services, or utilities furnished to the Premises and shall
not permit any lien or charge of any kind securing the repayment of borrowed
funds (including the deferred purchase price for any property) to accrue and
remain outstanding against the Premises.

    9.       ASSIGNMENT OF LEASES AND RENTS.  As additional security for the
Debt, the Mortgagor assigns to the Mortgagee all oral or written leases, and
the rents, issues, income and profits under all leases or licenses of the
Premises, present and future, including all rights conferred by MCL 554.231
et seq. and MCL 554.211 et seq.  This assignment shall be operative in the
event of default and during any foreclosure or other proceeding taken to
enforce this Mortgage, and during any redemption period.  The Mortgagor will
comply with all terms of all leases.

    10.      ASSIGNMENT OF INTEREST AS TENANT OR PURCHASER.  If the
Mortgagor's interest in the Premises is that of a tenant or a purchaser, the
Mortgagor also assigns, mortgages and warrants to the Mortgagee, as
additional security for the Debt, all of the Mortgagor's right, title and
interest in and to any leases, land contracts or other agreements by which
the Mortgagor is leasing or purchasing any part or all of the Premises,
including all modifications, renewals and extensions and all of the
Mortgagor's right, title or interest in any purchase options contained in
any lease or other agreement.  The Mortgagor agrees to pay each installment
of rent, principal and interest required to be paid by it under the lease,
land contract or other agreement when each installment becomes due and
payable whether by acceleration or otherwise.  The Mortgagor further agrees
to pay and perform all of its other obligations under the lease, land
contract or other agreement.

    If the Mortgagor defaults in the payment of any installment of rent,
principal, interest or in the payment or performance of any other obligation
under the lease, land contract or other agreement, the Mortgagee shall have
the right, but not the obligation, to pay the installment or installments
and to pay or perform the other obligations on behalf of and at the expense
of the Mortgagor.  On receipt by the Mortgagee from the landlord or seller
under the lease, land contract or other agreement of any written notice of
default by the Mortgagor, the Mortgagee may rely on the notice as cause to
take any action it deems necessary or reasonable to cure a default even if
the Mortgagor questions or denies the existence or nature of the default.

    11.      SECURITY AGREEMENT.  This Mortgage also constitutes a security
agreement within the meaning of the Michigan Uniform Commercial Code ("UCC")
and the Mortgagor grants to the Mortgagee a security interest in any
Equipment and other personal property included within the definition of
Premises.  Accordingly, the Mortgagee shall have all of the rights and
remedies available to a secured party under the UCC.  Upon the occurrence of
an event of default under this Mortgage, the Mortgagee shall have, in
addition to the remedies provided by this Mortgage, the right to use any
method of disposition of collateral authorized by the UCC with respect to
any portion of the Premises subject to the UCC.

    12.      REIMBURSEMENT OF ADVANCES.  If the Mortgagor fails to perform any
of its obligations under this Mortgage, or if any action or proceeding is
commenced which materially affects Mortgagee's interest in the Premises
(including but not limited to a lien priority dispute, eminent domain, code
enforcement, insolvency, bankruptcy or probate proceedings), then the
Mortgagee at its sole option may make appearances, disburse sums and take
any action it deems necessary to protect its interest (including but not
limited to disbursement of reasonable attorney's fees and entry upon the
Premises to make repairs).  Any amounts disbursed shall become additional
Debt, shall be immediately due and payable upon notice from the Mortgagee to
the Mortgagor, and shall bear interest at the highest rate permitted under
any instrument evidencing any of the Debt.

    13.      DUE ON TRANSFER.  If all or any part of the Premises or any
interest in the Premises is transferred without the Mortgagee's prior
written consent, it may, at its sole option, declare the Debt to be
immediately due and payable.

    14.      NO ADDITIONAL LIEN.  The Mortgagor covenants not to execute any
mortgage, security agreement, assignment of leases and rentals or other
agreement granting a lien against the interest of the Mortgagor in the
Premises, without the prior written consent of the Mortgagee, and then only
when the document granting that lien expressly provides that it shall be
subject to the lien of this Mortgage for the full amount secured by this
Mortgage, and shall also be subject and subordinate to any then existing or
future leases affecting the Premises.

    15.      EMINENT DOMAIN.  Notwithstanding any taking under the power of
eminent domain, alteration of the grade of any road, alley, or the like, or
other injury or damage to or decrease in value of the Premises by any public
or quasi-public authority or corporation, the Mortgagor shall continue to
pay the Debt in accordance with the terms of the underlying loan documents
until any award or payment shall have been actually received by the
Mortgagee.  By executing this Mortgage, the Mortgagor assigns the entire
proceeds of any award or payment and any interest to the Mortgagee.  The
proceeds shall be applied first toward reimbursement of all costs and
expenses of the Mortgagee, including reasonable attorney fees of the
Mortgagee in collecting the proceeds and then toward payment of the Debt
whether or not then due or payable, or the Mortgagee at its option may apply
all or any part of the proceeds to the alteration, restoration or rebuilding
of the Premises.

    16.      ENVIRONMENTAL PROVISIONS.  From time to time the Mortgagor or
Borrower has executed and delivered, and may in the future execute and
deliver, Environmental Certificates to the Mortgagee, which include
representations, warranties, covenants, an indemnification, and right of
entry.  The most recent Environmental Certificate shall supersede all prior
Environmental Certificates that have been executed, and its provisions shall
be deemed incorporated into this Mortgage.

    17.      EVENTS OF DEFAULT/ACCELERATION.  Upon the occurrence of any of
the following, the Mortgagee shall be entitled to exercise its remedies
under this Mortgage or as otherwise provided by law: (1) The Mortgagor or,
if other than the Mortgagor or all of the undersigned, any principal obligor

payable under the note(s), the guaranty, or any other agreement evidencing
the Debt; (2) the Mortgagor or Borrower (a) fails to observe or perform any

in part, or any guarantor fails to promptly perform under its guaranty; (4)
the Mortgagor or Borrower fails to pay when due any amount payable under any
note or agreement evidencing debt to the Mortgagee, or defaults under the
terms of any agreement or instrument relating to or securing any debt for
borrowed money owing to the Mortgagee; (5) a "reportable event" (as defined
in the Employee Retirement Income Security Act of 1974 as amended) occurs

Mortgagor or Borrower; (6) the Mortgagor or Borrower becomes insolvent or
unable to pay its debts as they become due; (7) the Mortgagor or Borrower
(a) makes an assignment for the benefit of Creditors, (b) consents to the

jurisdiction; (8) a custodian, receiver, or trustee is appointed for the
Mortgagor or Borrower or for a substantial part of its assets without its
consent and is not removed within 60 days after the appointment; (9)

bankruptcy, reorganization, liquidation, or similar laws of any
jurisdiction, and those proceedings remain undismissed for 60 days after

those proceedings; (10) any judgment is entered against the Mortgagor or

property of the Mortgagor or Borrower; (11) any proceedings are instituted
for the foreclosure or collection of any mortgage, judgment or lien
affecting the Premises; (12) the Mortgagor sells, transfers or hypothecates
any part of the Premises except as provided in this Mortgage without the

of the foregoing; or (15) there is a substantial change in the existing or
prospective financial condition of the Mortgagor or Borrower which the
Mortgagee in good faith determines to be materially adverse.

    18.       REMEDIES UPON DEFAULT.  Upon the occurrence of any of the events
of default set forth in this Mortgage, the Mortgagee is authorized to
commence foreclosure proceedings against the Premises through judicial
proceedings or by advertisement, at the option of the Mortgagee, and to sell
the Premises at public auction pursuant to law, and out of the proceeds to
retain all sums due the Mortgagee, including the costs of the sale and
reasonable attorney's fees, rendering any surplus to the Mortgagor.  The
Premises may be sold in one parcel as an entirety or in such parcels, manner
and order as Mortgagee may elect.  By executing this Mortgage, the Mortgagor
waives, in the event of foreclosure of this Mortgage or the enforcement by
the Mortgagee of any other rights and remedies in this Mortgage, any right
otherwise available in respect to marshalling of assets which secure the
Debt or to require the Mortgagee to pursue its remedies against any other
such assets.  The Mortgagor waives all rights to a hearing prior to sale in
connection with any foreclosure of this Mortgage by advertisement and all
notice requirements except as set forth in any applicable state statute
providing for foreclosure by advertisement.

    19.      PLEDGE.  If the Mortgagor is not liable for all or any part of
the Borrower's obligations to the Bank, then it agrees that:

     (a) If any monies become available to the Bank from the Borrower that
it can apply to any debt, the Bank may apply them to debt not secured by
this Mortgage.

     (b) Without notice to or the consent of the Mortgagor, the Bank may (i)
take any action it chooses against any Borrower, against any collateral for
the Debt, or against any other person liable for the Debt; (ii) release any
Borrower or any other person liable for the Debt, release any collateral for
the Debt, and neglect to perfect any interest in any such collateral; (iii)
forbear or agree to forbear from exercising any rights or remedies,
including any right to setoff, that it has against the Borrower, any other
person liable for the Debt, or any other collateral for the Debt; (iv)
extend to any Borrower additional Debt to be secured by this Mortgage; or
(v) renew, extend, modify or amend any Debt, and deal with the Borrower or
any other person liable for the Debt as it chooses.

     (c) None of the Mortgagor's obligations under this Mortgage shall be
affected by (i) any act or omission of the Bank; (ii) the voluntary or
involuntary liquidation, sale or other disposition of all or substantially
all of the assets of any Borrower; (iii) any receivership, insolvency,
bankruptcy, reorganization or other similar proceedings affecting any
Borrower or any of its assets; or (iv) any change in the composition or
structure of any Borrower or any Mortgagor, including a merger or
consolidation with any other entity.


     (d) The Bank's rights under this section and this Mortgage are
unconditional and absolute, regardless of the unenforceability of any
provision of any agreement between any Borrower and the Bank, or the
existence of any defense, setoff or counterclaim that a Borrower may be able
to assert against the Bank. 

     (e) It waives all rights of subrogation, contribution, reimbursement,
indemnity, exoneration, implied contract, recourse to security, and any
other claim (as that term is defined in the federal Bankruptcy Code, as
amended from time to time) that it may have or acquire in the future against
any Borrower, any other person liable for the Debt, or any collateral for
the Debt, because of the existence of this Mortgage, the Borrower's
performance under this Mortgage or the Debt, or the Bank's availing itself
of any rights or remedies under this Mortgage.

     (f) If any payment to the Bank, on any of the Debt is wholly or
partially invalidated, set aside, declared fraudulent or required to be
repaid to the Borrower or anyone representing the Borrower or the Borrower's
creditors under any bankruptcy or insolvency act or code, under any state or
federal law, or under common law or equitable principles, then this Mortgage
shall remain in full force and effect or be reinstated, as the case may be,
until payment in full to the Bank of the repaid amounts, and of the Debt. 
If this Mortgage must be reinstated, the Mortgagor agrees to execute and
deliver to the Bank new mortgages, if necessary, in form and substance
acceptable to the Bank, covering the Premises.

    20.      REPRESENTATIONS BY MORTGAGOR.  Each Mortgagor represents: (a)
that the execution and delivery of this Mortgage and the performance of the
obligations it imposes do not violate any law, do not conflict with any
agreement by which it is bound, and do not require the consent or approval
of any governmental authority or any third party; (b) that this Mortgage is
a valid and binding agreement, enforceable according to its terms; and (c)
that all balance sheets, profit and loss statements, and other financial
statements furnished to the Bank are accurate and fairly reflect the
financial condition of the organizations and persons to which they apply on
their effective dates, including contingent liabilities of every type, which
financial condition has not changed materially and adversely since those
dates.  Each Mortgagor, other than a natural person, further represents: (a)
that it is duly organized, existing and in good standing pursuant to the
laws under which it is organized; and (b) that the execution and delivery of
this Mortgage and the performance of the obligations it imposes (i) are
within its powers and have been duly authorized by all necessary action of
its governing body; and (ii) do not contravene the terms of its articles of
incorporation or organization, its by-laws, or any partnership, operating or
other agreements governing its affairs.

    21.      NOTICES.  Notice from one party to another relating to this
Mortgage shall be deemed effective if made in writing (including
telecommunications) and delivered to the recipient's address, telex number

delivery, (b) registered or certified mail, postage prepaid, with return
receipt requested, (c) first class or express mail, postage prepaid, (d)

business day after mailing or deposit with an overnight courier service if

be inapplicable to any judicial or non-judicial proceeding where Michigan
law governs the manner and timing of notices in foreclosure or receivership
proceedings.

    22.      MISCELLANEOUS.  If any provision of this Mortgage is in conflict
with any statute or rule of law or is otherwise unenforceable for any reason
whatsoever, then the provision shall be deemed null and void to the extent
of such conflict or unenforceability and shall be deemed severable from but
shall not invalidate any other provisions of this Mortgage. No waiver by the
Mortgagee of any right or remedy granted or failure to insist on strict
performance by the Mortgagor shall affect or act as a waiver of any right or
remedy of the Mortgagee, nor affect the subsequent exercise of the same
right or remedy by the Mortgagee for any subsequent default by the
Mortgagor, and all rights and remedies of the Mortgagee are cumulative.

    These promises and agreements shall bind and these rights shall be to the
benefit of the parties and their respective heirs, successors and assigns. 
If there is more than one Mortgagor or Borrower, their obligations under
this Mortgage shall be joint and several.

    This Mortgage shall be governed by Michigan law except to the extent it
is preempted by federal law or regulation.

    23.      WAIVER OF JURY TRIAL. The Mortgagee and the Mortgagor, after
consulting or having had the opportunity to consult with counsel, knowingly,
voluntarily and intentionally waive any right either of them may have to a
trial by jury in any litigation based upon or arising out of this Mortgage
or any related instrument or agreement, or any of the transactions
contemplated by this Mortgage, or any course of conduct, dealing, statements
(whether oral or written), or actions of either of them. Neither the
Mortgagee nor the Mortgagor shall seek to consolidate, by counterclaim or
otherwise, any 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 either the Mortgagee or the Mortgagor except by a written
instrument executed by both of them.

(MCL 554.231 et seq.)

The Premises are unencumbered except as follows: None.

("Permitted Encumbrances").  If the Premises are encumbered by Permitted
Encumbrances, the Mortgagor shall perform all obligations and make all
payments as required by the Permitted Encumbrances.  The Mortgagor shall
provide copies of all writings pertaining to Permitted Encumbrances, and the
Mortgagee is authorized to request and receive that information from any
other person without the consent or knowledge of the Mortgagor.

THE DEBT.  This Mortgage secures the following (the "Debt"):

(i) The note(s) dated February 19, 1997 n the principal amount(s) of
$3,500,000 and $250,000, maturing on August 31, 1997 and February 28, 2002
respectively executed and delivered by Mortgagor to the Mortgagee, together
with all extensions, renewals, modifications, and replacements; and

(ii) the guaranty of the debt of I.G.K. Industries, Inc. and Interface
Systems, International, Ltd. dated February 19, 1997 executed and delivered

(iii) ------------------------------------------------------ together with
all extensions, renewals, modifications and replacements; and

(iv) Future Advances and Cross-Lien:  All other present and future, direct
and indirect obligations and liabilities of the Mortgagor, or any one or
more of them, with or without others, however evidenced, to the Mortgagee,
and all future advances, whether obligatory or optional, from the Mortgagee
to the Mortgagor, or any one or more of them, with or without others.  (This
shall not apply to any obligation or debt incurred for personal, family or
household purposes unless the note or guaranty expressly states that it is
secured by this Mortgage.)  Notwithstanding the foregoing, if this Mortgage
is a residential future advance mortgage, as defined in MCL 565.901, the
maximum principal amount secured by this Mortgage is $----------, excluding
protective advances as defined in MCL 565.901.

This Mortgage shall also secure the performance of the promises and
agreements contained in this Mortgage.

The Mortgagor promises and agrees as follows:

    1.       PAYMENT OF DEBT; PERFORMANCE OF OBLIGATIONS.  The Mortgagor shall
promptly pay when due, whether by acceleration or otherwise, the Debt for
which the Mortgagor is liable, and shall promptly perform all obligations to
which the Mortgagor has agreed under the terms of this Mortgage and any loan
documents evidencing the Debt.

    2.       TAXES.  The Mortgagor shall pay, when due, and before any
interest, collection fees or penalties shall accrue, all taxes, assessments,
fines, impositions, and other charges which may become a lien prior to this
Mortgage.  Should the Mortgagor fail to make such payments, the Mortgagee
may, at its option and at the expense of the Mortgagor, pay the amounts due
for the account of the Mortgagor.  Upon the request of the Mortgagee, the
Mortgagor shall immediately furnish to the Mortgagee all notices of amounts
due and receipts evidencing payment.  The Mortgagor shall promptly notify
the Mortgagee of any lien on all or any part of the Premises and shall
promptly discharge any unpermitted lien or encumbrance.

    3.       CHANGE IN TAXES.  In the event of the passage of any law or
regulation, state, federal or municipal, subsequent to the date of this
Mortgage in any manner changing or modifying the laws now in force governing
the taxation of mortgages or debts secured by mortgages, or the manner of
collecting such taxes, the Debt shall become due and payable immediately at
the option of the Mortgagee.

    4.       INSURANCE.  Until the debt is fully paid the Mortgagor shall keep
the Premises and the present and future buildings and other improvements on
the Premises, constantly insured for the benefit of the Mortgagee, without
any reduction in coverage based on the Mortgagor's acts, against fire and
such other hazards and risks customarily covered by the standard form of
extended coverage endorsement available in the State of Michigan, including
risks of vandalism and malicious mischief, and shall further provide flood
insurance if the Premises are situated in an area designated as a flood risk
area by the Director of the Federal Emergency Management Agency or as
otherwise required by the Flood Disaster Protection Act of 1973 and
regulations issued under it), and such other appropriate insurance as the
Mortgagee may require from time to time.  All insurance policies and
renewals must be acceptable to Mortgagee, must provide for payment to the
Mortgagee in the event of loss, must require thirty (30) days notice to the
Mortgagee in the event of nonrenewal or cancellation, and must be delivered
to the Mortgagee.  Should the Mortgagor fail to insure or fail to pay the
premiums on any insurance or fail to deliver the policies or certificates or
renewals to the Mortgagee then the Mortgagee at its option may have the
insurance written or renewed and pay the premiums for the account of the
Mortgagor.  In the event of loss or damage, the proceeds of the insurance
shall be paid to the Mortgagee alone.  No loss or damage shall itself reduce
the Debt.  The Mortgagee is authorized to adjust and compromise a loss
without the consent of the Mortgagor, to collect, receive and receipt for
any proceeds in the name of the Mortgagee and the Mortgagor and to endorse
the Mortgagor's name upon any check in payment of proceeds.  The proceeds
shall be applied first toward reimbursement of all costs and expenses of the
Mortgagee in collecting the proceeds and then toward payment of the Debt or
any portion of it, whether or not then due or payable, or the Mortgagee at
its option may apply the proceeds, or any part to the repair or rebuilding
of the Premises provided that Mortgagor is not then or at any time during
the course of restoration of the Premises in default under this Mortgage and
has complied with all requirements for application of the proceeds to
restoration of the Premises as Mortgagee, in its sole discretion may
establish.

    5.       RESERVES FOR TAXES AND INSURANCE.  The Mortgagor shall, if
requested by the Mortgagee, pay to the Mortgagee, at the time of and in
addition to the scheduled installments of principal or interest due under
the Debt, a sum equal to (a) the amount estimated by the Mortgagee to be
sufficient to enable it to pay, at least thirty (30) days before they become
due and payable, all taxes, assessments and other similar charges levied
against the Premises, plus (b) the amount of the annual premiums on any
policies of insurance required to be carried by the Mortgagor divided by (c)
the number of installments due each year.  These sums may be commingled with
the general funds of the Mortgagee, and no interest shall be payable on them
nor shall these sums be deemed to be held in trust for the benefit of the
Mortgagor.  Upon notice at any time, the Mortgagor will, within ten (10)
days, deposit such additional sum as may be required for the payment of
increased taxes, assessments, charges or premiums.

         Notwithstanding payment of any sums by the Mortgagor to the
Mortgagee under the terms of this paragraph, the Mortgagee shall have no
obligation to pay any taxes, assessments, premiums, or other similar charges
relating to or levied against the Premises.  The obligation of the Mortgagor
to pay taxes, assessments, charges, and insurance premiums is not affected
or modified by the arrangements set out in this paragraph.  Payment by the
Mortgagee on any one or more occasions of all or any portion of the taxes,
assessments, premiums, or other similar charges relating to or levied
against the Premises shall not be construed as obligating the Mortgagee to
pay any taxes, assessments, premiums, or other similar charges on any other
occasion.  If the Mortgagee elects to pay any taxes, assessments, or other
similar charges, it shall not be required to do so at any time prior to the
date on which penalties, interest, and/or collection fees begin to accrue. 
If the Mortgagee elects to pay any premium on any policy of insurance
required to be carried by the Mortgagor, it may do so at any time prior to
cancellation of the policy.

         In the event of foreclosure of this Mortgage, any of the moneys then
remaining on deposit with the Mortgagee or its agent shall be applied
against the Debt prior to the commencement of foreclosure proceedings.   The
obligation of the Mortgagor to pay taxes, assessments, charges or insurance
premiums is not affected or modified by the arrangements set out in this
section. Any default by the Mortgagor in the performance of the provisions
of this section shall constitute a default under this Mortgage.  The
Mortgagee shall not request the reserves provided for in this section as
long as there is no default by the Mortgagor under this Mortgage and the
Mortgagor retains title to the Premises.

         6.       WASTE.  The Mortgagor shall keep the Premises in good
repair, shall not commit or permit waste on the Premises nor do any other
act causing the Premises to become less valuable.  Non-payment of taxes and
cancellation of insurance shall each constitute waste as provided by MCL
600.2927.  The Mortgagor consents to the appointment of a receiver under
this statute should the Mortgagee elect to seek such relief.  Should the
Mortgagor fail to effect any necessary repairs, the Mortgagee may at its
option and at the expense of the Mortgagor make the repairs for the account
of the Mortgagor.  The Mortgagor shall use and maintain the Premises in
conformance with all applicable laws, ordinances and regulations.  The
Mortgagee or its authorized agent shall have the right to enter upon and
inspect the Premises at all reasonable times.

         7.       ALTERATIONS, REMOVAL.  No building, structure, improvement,
fixture or personal property constituting any part of the Premises shall be
removed, demolished or substantially altered without the prior written
consent of the Mortgagee.

         8.       PAYMENT OF OTHER OBLIGATIONS.  The Mortgagor shall also pay
all other obligations which may become liens or charges against the Premises
for any present or future repairs or improvements made on the Premises, or
for any other goods, services, or utilities furnished to the Premises and
shall not permit any lien or charge of any kind securing the repayment of
borrowed funds (including the deferred purchase price for any property) to
accrue and remain outstanding against the Premises.

         9.       ASSIGNMENT OF LEASES AND RENTS.  As additional security for
the Debt, the Mortgagor assigns to the Mortgagee all oral or written leases,
and the rents, issues, income and profits under all leases or licenses of
the Premises, present and future, including all rights conferred by MCL
554.231 et seq. and MCL 554.211 et seq.  This assignment shall be operative
in the event of default and during any foreclosure or other proceeding taken
to enforce this Mortgage, and during any redemption period.  The Mortgagor
will comply with all terms of all leases.

         10.      ASSIGNMENT OF INTEREST AS TENANT OR PURCHASER.  If the
Mortgagor's interest in the Premises is that of a tenant or a purchaser, the
Mortgagor also assigns, mortgages and warrants to the Mortgagee, as
additional security for the Debt, all of the Mortgagor's right, title and
interest in and to any leases, land contracts or other agreements by which
the Mortgagor is leasing or purchasing any part or all of the Premises,
including all modifications, renewals and extensions and all of the
Mortgagor's right, title or interest in any purchase options contained in
any lease or other agreement.  The Mortgagor agrees to pay each installment
of rent, principal and interest required to be paid by it under the lease,
land contract or other agreement when each installment becomes due and
payable whether by acceleration or otherwise.  The Mortgagor further agrees
to pay and perform all of its other obligations under the lease, land
contract or other agreement.

         If the Mortgagor defaults in the payment of any installment of rent,
principal, interest or in the payment or performance of any other obligation
under the lease, land contract or other agreement, the Mortgagee shall have
the right, but not the obligation, to pay the installment or installments
and to pay or perform the other obligations on behalf of and at the expense
of the Mortgagor.  On receipt by the Mortgagee from the landlord or seller
under the lease, land contract or other agreement of any written notice of
default by the Mortgagor, the Mortgagee may rely on the notice as cause to
take any action it deems necessary or reasonable to cure a default even if
the Mortgagor questions or denies the existence or nature of the default.

         11.      SECURITY AGREEMENT.  This Mortgage also constitutes a
security agreement within the meaning of the Michigan Uniform Commercial
Code ("UCC") and the Mortgagor grants to the Mortgagee a security interest
in any Equipment and other personal property included within the definition
of Premises.  Accordingly, the Mortgagee shall have all of the rights and
remedies available to a secured party under the UCC.  Upon the occurrence of
an event of default under this Mortgage, the Mortgagee shall have, in
addition to the remedies provided by this Mortgage, the right to use any
method of disposition of collateral authorized by the UCC with respect to
any portion of the Premises subject to the UCC.

         12.      REIMBURSEMENT OF ADVANCES.  If the Mortgagor fails to
perform any of its obligations under this Mortgage, or if any action or
proceeding is commenced which materially affects Mortgagee's interest in the
Premises (including but not limited to a lien priority dispute, eminent
domain, code enforcement, insolvency, bankruptcy or probate proceedings),
then the Mortgagee at its sole option may make appearances, disburse sums
and take any action it deems necessary to protect its interest (including
but not limited to disbursement of reasonable attorney's fees and entry upon
the Premises to make repairs).  Any amounts disbursed shall become
additional Debt, shall be immediately due and payable upon notice from the
Mortgagee to the Mortgagor, and shall bear interest at the highest rate
permitted under any instrument evidencing any of the Debt.

         13.      DUE ON TRANSFER.  If all or any part of the Premises or any
interest in the Premises is transferred without the Mortgagee's prior
written consent, it may, at its sole option, declare the Debt to be
immediately due and payable.

         14.      NO ADDITIONAL LIEN.  The Mortgagor covenants not to execute
any mortgage, security agreement, assignment of leases and rentals or other
agreement granting a lien against the interest of the Mortgagor in the
Premises, without the prior written consent of the Mortgagee, and then only
when the document granting that lien expressly provides that it shall be
subject to the lien of this Mortgage for the full amount secured by this
Mortgage, and shall also be subject and subordinate to any then existing or
future leases affecting the Premises.

         15.      EMINENT DOMAIN.  Notwithstanding any taking under the power
of eminent domain, alteration of the grade of any road, alley, or the like,
or other injury or damage to or decrease in value of the Premises by any
public or quasi-public authority or corporation, the Mortgagor shall
continue to pay the Debt in accordance with the terms of the underlying loan
documents until any award or payment shall have been actually received by
the Mortgagee.  By executing this Mortgage, the Mortgagor assigns the entire
proceeds of any award or payment and any interest to the Mortgagee.  The
proceeds shall be applied first toward reimbursement of all costs and
expenses of the Mortgagee, including reasonable attorney fees of the
Mortgagee in collecting the proceeds and then toward payment of the Debt
whether or not then due or payable, or the Mortgagee at its option may apply
all or any part of the proceeds to the alteration, restoration or rebuilding
of the Premises.

         16.      ENVIRONMENTAL PROVISIONS.  From time to time the Mortgagor
or Borrower has executed and delivered, and may in the future execute and
deliver, Environmental Certificates to the Mortgagee, which include
representations, warranties, covenants, an indemnification, and right of
entry.  The most recent Environmental Certificate shall supersede all prior
Environmental Certificates that have been executed, and its provisions shall
be deemed incorporated into this Mortgage.

         17.      EVENTS OF DEFAULT/ACCELERATION.  Upon the occurrence of any
of the following, the Mortgagee shall be entitled to exercise its remedies
under this Mortgage or as otherwise provided by law: (1) The Mortgagor or,
if other than the Mortgagor or all of the undersigned, any principal obligor
of the Debt (collectively, the "Borrower") fails to pay when due any amount
payable under the note(s), the guaranty, or any other agreement evidencing
the Debt; (2) the Mortgagor or Borrower (a) fails to observe or perform any
other term of the note(s), the guaranty, or any other agreement evidencing

in any financial statement or other information delivered to the Mortgagee;
(3) there is a default under the terms of this Mortgage, any loan agreement,
mortgage, security agreement, or other document executed as part of the Debt

in part, or any guarantor fails to promptly perform under its guaranty; (4)
the Mortgagor or Borrower fails to pay when due any amount payable under any
note or agreement evidencing debt to the Mortgagee, or defaults under the
terms of any agreement or instrument relating to or securing any debt for
borrowed money owing to the Mortgagee; (5) a "reportable event" (as defined
in the Employee Retirement Income Security Act of 1974 as amended) occurs
that would permit the Pension Benefit Guaranty Corporation to terminate any
employee benefit plan of the Mortgagor or Borrower or any affiliate of the
Mortgagor or Borrower; (6) the Mortgagor or Borrower becomes insolvent or
unable to pay its debts as they become due; (7) the Mortgagor or Borrower
(a) makes an assignment for the benefit of Creditors, (b) consents to the
appointment of a custodian, receiver, or trustee for itself or for a
substantial part of its assets, or (c) commences any proceeding under any
bankruptcy, reorganization, liquidation, insolvency or similar laws of any
jurisdiction; (8) a custodian, receiver, or trustee is appointed for the
Mortgagor or Borrower or for a substantial part of its assets without its
consent and is not removed within 60 days after the appointment; (9)
proceedings are commenced against the Mortgagor or Borrower under any
bankruptcy, reorganization, liquidation, or similar laws of any
jurisdiction, and those proceedings remain undismissed for 60 days after
commencement; or the Mortgagor or Borrower consents to the commencement of
those proceedings; (10) any judgment is entered against the Mortgagor or
Borrower, or any attachment, levy, or garnishment is issued against any
property of the Mortgagor or Borrower; (11) any proceedings are instituted
for the foreclosure or collection of any mortgage, judgment or lien
affecting the Premises; (12) the Mortgagor sells, transfers or hypothecates
any part of the Premises except as provided in this Mortgage without the
prior written consent of the Mortgagee; (13) the Mortgagor or Borrower dies;
(14) the Mortgagor or Borrower, without the Mortgagee's written consent, (a)
is dissolved, (b) merges or consolidates with any third party, (c) leases,
sells or otherwise conveys a material part of its assets or business outside
the ordinary course of its business, (d) leases, purchases or otherwise
acquires a material part of the assets of any other corporation or business
entity outside the ordinary course of its business, or (e) agrees to do any
of the foregoing; or (15) there is a substantial change in the existing or
prospective financial condition of the Mortgagor or Borrower which the
Mortgagee in good faith determines to be materially adverse.

         18.       REMEDIES UPON DEFAULT.  Upon the occurrence of any of the
events of default set forth in this Mortgage, the Mortgagee is authorized to
commence foreclosure proceedings against the Premises through judicial
proceedings or by advertisement, at the option of the Mortgagee, and to sell
the Premises at public auction pursuant to law, and out of the proceeds to
retain all sums due the Mortgagee, including the costs of the sale and
reasonable attorney's fees, rendering any surplus to the Mortgagor.  The
Premises may be sold in one parcel as an entirety or in such parcels, manner
and order as Mortgagee may elect.  By executing this Mortgage, the Mortgagor
waives, in the event of foreclosure of this Mortgage or the enforcement by
the Mortgagee of any other rights and remedies in this Mortgage, any right
otherwise available in respect to marshalling of assets which secure the
Debt or to require the Mortgagee to pursue its remedies against any other
such assets.  The Mortgagor waives all rights to a hearing prior to sale in
connection with any foreclosure of this Mortgage by advertisement and all
notice requirements except as set forth in any applicable state statute
providing for foreclosure by advertisement.

         19.      PLEDGE.  If the Mortgagor is not liable for all or any part
of the Borrower's obligations to the Bank, then it agrees that:

                  (a) If any monies become available to the Bank from the
Borrower that it can apply to any debt, the Bank may apply them to debt not
secured by this Mortgage.

                  (b) Without notice to or the consent of the Mortgagor, the
Bank may (i) take any action it chooses against any Borrower, against any
collateral for the Debt, or against any other person liable for the Debt;
(ii) release any Borrower or any other person liable for the Debt, release
any collateral for the Debt, and neglect to perfect any interest in any such
collateral; (iii) forbear or agree to forbear from exercising any rights or
remedies, including any right to setoff, that it has against the Borrower,
any other person liable for the Debt, or any other collateral for the Debt;
(iv) extend to any Borrower additional Debt to be secured by this Mortgage;
or (v) renew, extend, modify or amend any Debt, and deal with the Borrower
or any other person liable for the Debt as it chooses.

                  (c) None of the Mortgagor's obligations under this Mortgage
shall be affected by (i) any act or omission of the Bank; (ii) the voluntary
or involuntary liquidation, sale or other disposition of all or
substantially all of the assets of any Borrower; (iii) any receivership,
insolvency, bankruptcy, reorganization or other similar proceedings
affecting any Borrower or any of its assets; or (iv) any change in the
composition or structure of any Borrower or any Mortgagor, including a
merger or consolidation with any other entity.

                  (d) The Bank's rights under this section and this Mortgage
are unconditional and absolute, regardless of the unenforceability of any
provision of any agreement between any Borrower and the Bank, or the
existence of any defense, setoff or counterclaim that a Borrower may be able
to assert against the Bank. 

                  (e) It waives all rights of subrogation, contribution,
reimbursement, indemnity, exoneration, implied contract, recourse to
security, and any other claim (as that term is defined in the federal
Bankruptcy Code, as amended from time to time) that it may have or acquire
in the future against any Borrower, any other person liable for the Debt, or
any collateral for the Debt, because of the existence of this Mortgage, the
Borrower's performance under this Mortgage or the Debt, or the Bank's
availing itself of any rights or remedies under this Mortgage.

                  (f) If any payment to the Bank, on any of the Debt is wholly
or partially invalidated, set aside, declared fraudulent or required to be
repaid to the Borrower or anyone representing the Borrower or the Borrower's
creditors under any bankruptcy or insolvency act or code, under any state or
federal law, or under common law or equitable principles, then this Mortgage
shall remain in full force and effect or be reinstated, as the case may be,
until payment in full to the Bank of the repaid amounts, and of the Debt. 
If this Mortgage must be reinstated, the Mortgagor agrees to execute and
deliver to the Bank new mortgages, if necessary, in form and substance
acceptable to the Bank, covering the Premises.

a valid and binding agreement, enforceable according to its terms; and (c)
that all balance sheets, profit and loss statements, and other financial
statements furnished to the Bank are accurate and fairly reflect the
financial condition of the organizations and persons to which they apply on
their effective dates, including contingent liabilities of every type, which
financial condition has not changed materially and adversely since those
dates.  Each Mortgagor, other than a natural person, further represents: (a)
that it is duly organized, existing and in good standing pursuant to the
laws under which it is organized; and (b) that the execution and delivery of
this Mortgage and the performance of the obligations it imposes (i) are
within its powers and have been duly authorized by all necessary action of
its governing body; and (ii) do not contravene the terms of its articles of
incorporation or organization, its by-laws, or any partnership, operating or
other agreements governing its affairs.

         21.      NOTICES.  Notice from one party to another relating to this
Mortgage shall be deemed effective if made in writing (including

receipt requested, (c) first class or express mail, postage prepaid, (d)
Federal Express, Purolator Courier or like overnight courier service, or (e)

be inapplicable to any judicial or non-judicial proceeding where Michigan
law governs the manner and timing of notices in foreclosure or receivership
proceedings.

         22.      MISCELLANEOUS.  If any provision of this Mortgage is in
conflict with any statute or rule of law or is otherwise unenforceable for
any reason whatsoever, then the provision shall be deemed null and void to
the extent of such conflict or unenforceability and shall be deemed
severable from but shall not invalidate any other provisions of this
Mortgage. No waiver by the Mortgagee of any right or remedy granted or
failure to insist on strict performance by the Mortgagor shall affect or act
as a waiver of any right or remedy of the Mortgagee, nor affect the
subsequent exercise of the same right or remedy by the Mortgagee for any
subsequent default by the Mortgagor, and all rights and remedies of the
Mortgagee are cumulative.

         These promises and agreements shall bind and these rights shall be
to the benefit of the parties and their respective heirs, successors and
assigns.  If there is more than one Mortgagor or Borrower, their obligations
under this Mortgage shall be joint and several.

         This Mortgage shall be governed by Michigan law except to the extent
it is preempted by federal law or regulation.

         23.      WAIVER OF JURY TRIAL. The Mortgagee and the Mortgagor, after
consulting or having had the opportunity to consult with counsel, knowingly,
voluntarily and intentionally waive any right either of them may have to a
trial by jury in any litigation based upon or arising out of this Mortgage
or any related instrument or agreement, or any of the transactions
contemplated by this Mortgage, or any course of conduct, dealing, statements
(whether oral or written), or actions of either of them. Neither the
Mortgagee nor the Mortgagor shall seek to consolidate, by counterclaim or
otherwise, any 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 either the Mortgagee or the Mortgagor except by a written
instrument executed by both of them.

                                CONTINUING GUARANTY



GUARANTY.  To induce NBD Bank, N.A. (the "Bank"), of 611 Woodward Avenue,
Detroit, Michigan 48226-3497 at its option, to make loans, extend or
continue credit or some other benefit, including letters of credit and
foreign exchange contracts, present or future, direct or indirect, and
whether several, joint or joint and several (referred to collectively as
"Liabilities"), to Interface Systems, Inc., and its successors (the
"Borrower"), and because the undersigned (the "Guarantor") has determined
that executing this Guaranty is in its interest and to its financial
benefit, the Guarantor absolutely and unconditionally guaranties to the
Bank, as primary obligor and not merely as surety, that the Liabilities will
be paid when due, whether by acceleration or otherwise.  The Guarantor will
not only pay the Liabilities, but will also reimburse the Bank for accrued
and unpaid interest, and any expenses, including reasonable attorneys' fees,
that the Bank may pay in collecting from the Borrower or the Guarantor, and
for liquidating any collateral.

LIMITATION:  The Guarantor's obligation under this Guaranty is UNLIMITED. 
Notwithstanding the foregoing, if these blank lines are completed,
regardless of the amount of Liabilities outstanding at any time, the
Guarantor's obligation under this Guaranty shall not exceed the principal
amount of   N/A        and 00/100 DOLLARS ($   N/A          ), plus
interest, expenses, and fees.  Unless otherwise specified below. the
Guarantor's obligation shall be payable in U.S. Dollars.

CONTINUED RELIANCE:  The Bank may continue to make loans or extend credit to
the Borrower based on this Guaranty until it receives written notice of
termination from the Guarantor.  That notice shall be effective at the
opening of the Bank for business on the day after receipt of the notice.  If
terminated, the Guarantor will continue to be liable to the Bank for any
Liabilities created, assumed or committed to at the time the termination
becomes effective, and all subsequent renewals, extensions, modifications
and amendments of the Liabilities.

SECURITY.  As security for the Guaranty, the Guarantor grants to the Bank a
continuing security interest in the following described property and all of
its additions, substitutions, increments, proceeds and products, whether now
owned or later acquired (the "Collateral"):

1.      All securities and other property of the Guarantor in the custody,
        possession or control of the Bank (other than property held by the
        Bank solely in a fiduciary capacity);

2.      All property or securities declared or acknowledged to constitute
        security for any past, present or future liability, direct or
        indirect of the Guarantor to the Bank;

3.      All balances of deposit accounts of the Guarantor with the Bank;

4.      The following additional property of the Guarantor:   accounts
        receivable, inventory, machinery & equipment, general intangibles,
        and all other assets .

The Bank has the right at any time to apply its own debt or liability to the
Guarantor in whole or partial payment of this Guaranty or other present or
future liabilities, direct or indirect, without any requirement for mutual
maturity.

If the Guarantor fails to pay any amount owing under this Guaranty, the Bank
shall has all of the rights and remedies provided by law or under any other
agreement to liquidate or foreclose on and sell the Collateral, including
but not limited to the rights and remedies of a secured party under the
Uniform Commercial Code.  These rights and remedies are cumulative and not
exclusive.  If the Guarantor is entitled to notice, that requirement is met
if the Bank sends notice at least seven (7) days prior to the date of sale,
disposition or other event which requires notice.  The proceeds of any sale
shall be applied first to expenses, then toward payment of the amount owing
under this Guaranty.  The Bank may cause all or any part of the Collateral
to be transferred to or registered in its name or in the name of any other
person or business entity, with or without designation of the capacity of
that nominee.

INCORPORATION:  (This paragraph applies if the blanks are filled in.)  The
Guarantor agrees that as long as any Liability remains outstanding, the
covenants and events of default in the Credit Authorization Agreement dated
February 19, 1997 between NBD Bank and the Guarantor, as amended (the
"Agreement"), are incorporated by reference.  Those covenants and events
remain in force until this Guaranty is no longer in force, notwithstanding
any termination of the Agreement.

NEGATIVE PLEDGE:  The Guarantor will not allow any lien to exist on any of
its property, except liens known to the Bank and existing on the date of
this Guaranty, and new liens which, in aggregate, total less than $  N/A  .

        For purposes of the following paragraphs, "any collateral" shall
        include the Guarantor's Collateral and any other collateral securing
        the Liabilities.          

ACTION REGARDING BORROWER:  If any monies become available that the Bank can
apply to the Liabilities, the Bank may apply them in any manner it chooses,
including but not limited to applying them against liabilities which are not
covered by this Guaranty.  The Bank may take any action against the
Borrower, any collateral, or any other person liable for any of the
Liabilities.  The Bank may release the Borrower or anyone else from the
Liabilities, either in whole or in part, or release any collateral, and need
not perfect a security interest in any collateral.  The Bank does not have
to exercise any rights that it has against the Borrower or anyone else, or
make any effort to realize on any collateral or right of set-off.  If the
Borrower requests more credit or any other benefit, the Bank may grant it
and the Bank may grant renewals, extensions, modifications and amendments of
the Liabilities and otherwise deal with the Borrower or any other person as
the Bank sees fit and as if this Guaranty were not in effect.  The
Guarantor's obligations under this Guaranty shall not be released or
affected by (a) any act or omission of the Bank, (b) the voluntary or
involuntary liquidation, sale or other disposition of all or substantially
all of the assets of the Borrower, or any receivership, insolvency,
bankruptcy, reorganization, or other similar proceedings affecting the
Borrower or any of its assets, or (c) any change in the composition or
structure of the Borrower or Guarantor, including a merger or consolidation
with any other person or entity.

NATURE OF GUARANTY:  This Guaranty is a guaranty of payment and not of
collection.  Therefore, the Bank may insist that the Guarantor pay
immediately, and the Bank is not required to attempt to collect first from
the Borrower, any collateral, or any other person liable for the
Liabilities.  The obligation of the Guarantor shall be subject to no
conditions of any kind, and shall be absolute, regardless of the
unenforceability of any provisions of any agreement between the Borrower and
the Bank, or the existence of any defense, setoff or counterclaim which the
Borrower may assert.

OTHER GUARANTORS:  If there is more than one Guarantor, the obligations
under this Guaranty shall be joint and several.  In addition, each Guarantor
shall be jointly and severally liable with any other guarantor of the
Liabilities.  If the Bank elects to enforce its rights against less than all
guarantors of the Liabilities, that election shall not release Guarantor
from its obligations under this Guaranty.  The compromise or release of any
of the obligations of any of the other guarantors or the Borrower shall not
serve to waive, alter or release the Guarantor's obligations.  This Guaranty
is not conditioned on anyone else executing this or any other guaranty.

RIGHTS OF SUBROGATION:  The Guarantor agrees not to enforce any rights of
subrogation, contribution, or indemnification that it has against the
Borrower, any entity liable for the Liabilities, or any collateral, until
the Liabilities are fully paid, even if all Liabilities are not covered by
this Guaranty.  The Guarantor further agrees that if any payments to the
Bank on the Liabilities are in whole or in part invalidated, declared to be
fraudulent or preferential, set aside or required to be repaid to a trustee,
receiver or any other party under any bankruptcy act or code, state or
federal law, common law or equitable doctrine, this Guaranty and the Bank's
interest in any collateral remain in full force and effect (or be reinstated
as the case may be) until payment in full of those amounts.  That payment is
due on demand.

WAIVERS:  The Guarantor waives any right it may have to receive notice of
the following matters before the Bank enforces any of its rights:  (a) the
Bank's acceptance of this Guaranty, (b) any credit that the Bank extends to
the Borrower, (c) the Borrower's default, (d) any demand, or (e) any action
that the Bank takes regarding the Borrower, anyone else, any collateral, or
any Liability, which it might be entitled to by law or under any other
agreement.  Any waiver shall affect only the specific terms and time period
stated in the waiver.  The Bank may waive or delay enforcing any of its
rights without losing them.  No modification or waiver of this Guaranty
shall be effective unless it is in writing and signed by the party against
whom it is being enforced.

REPRESENTATIONS BY GUARANTOR:   Each Guarantor represents that:  (a) the
execution and delivery of this Agreement and the performance of the
obligations it imposes do not violate any law, conflict with any agreement
by which it is bound, or require the consent or approval of any governmental
authority or any third party; (b) this Agreement is a valid and binding
agreement enforceable according to its terms; and (c) all balance sheets,
profit and loss statements, and other financial statements furnished to the
Bank are accurate and fairly reflect the financial condition of the
organizations and persons to which they apply on their effective dates,
including contingent liabilities of every type, which financial condition
has not changed materially and adversely since those dates.  Each Guarantor,
other than a natural person, further represents that: (a) it is duly
organized, existing and in good standing under the laws where it is
organized; and (b) the execution and delivery of this note and the
performance of the obligations it imposes (i) are within its powers; (ii)
have been duly authorized by all necessary action of its governing body; and
(iii) do not contravene the terms of its articles of incorporation or
organization, its by-laws or any agreement governing its affairs.

NOTICES:  Notice from one party to another relating to this Guaranty shall
be deemed effective if made in writing (including telecommunications) and
delivered to the recipient's address, telex number or telecopier number set
forth under its name by any of the following means:  (a) hand delivery, (b)
registered or certified mail, postage prepaid, with return receipt
requested, (c) first class or express mail, postage prepaid, (d) Federal
Express, Purolator Courier or like overnight courier service or (e)
telecopy, telex or other wire transmission with request for assurance of
receipt in a manner typical with respect to communications of that type.

the next business day after mailing or deposit with an overnight courier
service if delivered by express mail or overnight courier.  Notwithstanding
the foregoing, notice of termination of this Guaranty shall be deemed
received only upon the receipt of actual written notice by the Bank in
accordance with the paragraph above labeled "Continued Reliance."

LAW AND JUDICIAL FORUM THAT APPLY:  This agreement is governed by Michigan
law.  The Guarantor agrees that any legal action or proceeding against it
with respect to any of its obligations under this Guaranty may be brought in
any state or federal court located in the State of Michigan, as the Bank in
its sole discretion may elect.  By the execution and delivery of this
Guaranty, the Guarantor submits to and accepts, with regard to any such
action or proceeding, for itself and in respect of its property, generally
and unconditionally. the jurisdiction of those courts.  The Guarantor waives
any claim that the State of Michigan is not a convenient forum or the proper
venue for any such suit, action or proceeding.

FOREIGN CURRENCY.  (This paragraph applies if the blanks are filled in.) 
This Guaranty arises in the context of an international transaction, and the
specification of payment in the following currency                           
              ("Foreign Currency") at                                        
 ("Conversion Location") is of the essence.  The Foreign Currency is the
currency of account and payment under this Guaranty.  The obligation of the
Guarantor is not discharged by an amount paid in any other currency or at
another place, whether pursuant to a judgment or otherwise, to the extent
that the amount so paid, on prompt conversion into the Foreign Currency and
transfer to the Conversion Location under normal banking procedure, does not
yield the amount of Foreign Currency due under this Guaranty.  

MISCELLANEOUS:  The Guarantor's liability under this Guaranty is independent
of its liability under any other guaranty previously or subsequently
executed by the Guarantor or any one of them, singularly or together with
others, as to all or any part of the Liabilities. and may be enforced for
the full amount of this Guaranty regardless of the Guarantor's liability
under any other guaranty.  This Guaranty binds the Guarantor and its heirs,
successors and assigns, and benefits the Bank and its successors and
assigns.  The use of headings shall not limit the provisions of this
Guaranty.  All discussions and documents arising between this Guaranty and
the last guaranty signed by the Guarantor as to the Borrower are merged into
this Guaranty.

WAIVER OF JURY TRIAL:  The Bank and the Guarantor, after consulting or
having had the opportunity to consult with counsel, knowingly, voluntarily
and intentionally waive any right either of them may have to a trial by jury
in any litigation based upon or arising out of this Guaranty or any related
instrument or agreement, or any of the transactions contemplated by this
Guaranty, or any course of conduct, dealing, statement (whether oral or
written), or actions of either of them.  Neither the Bank nor the Guarantor
shall seek to consolidate, by counterclaim or otherwise, any 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 either the Bank or the
Guarantor except by a written instrument executed by both of them.

Dated:  February 19, 1997

debts as they become due.

6.      Any Guarantor or Borrower (i) makes an assignment for the benefit of
creditors; (ii) consents to the appointment of a custodian, receiver, or
trustee for itself or for a substantial part of its assets; or (iii)
commences any proceeding under any bankruptcy, reorganization, liquidation,
insolvency or similar laws of any jurisdiction.

7.      A custodian, receiver or trustee is appointed for any Guarantor or
Borrower or for a substantial part of its assets without its consent, and is
not removed within 60 days after the appointment.

8.      Proceedings are commenced against any Guarantor or Borrower under any
bankruptcy, reorganization, liquidation, insolvency or similar laws of any
jurisdiction, and they remain dismissed for 60 days after commencement; or
any Guarantor or Borrower consents to the commencement of those proceedings.

9.      Any judgment is entered against any Guarantor or Borrower, or any
attachment, levy, or garnishment is issued against any property of any
Guarantor or Borrower, where the USD equivalent of the claim exceeds $ N/A.

10.     Any Guarantor or Borrower dies.

11.     Any Guarantor or Borrower, without the Bank's written consent, (i) is

13.     There is a substantial change in the existing or prospective
financial condition of any Guarantor or Borrower which the Bank in good

14.     The Bank in good faith deems itself insecure.

REMEDIES ON DEFAULT:  In addition, the Bank has all of the rights and
remedies provided by law or under any other agreement to liquidate or
foreclose on and sell the Collateral, including but not limited to the
rights and remedies of a secured part under the Uniform Commercial Code. 
These rights and remedies are cumulative and not exclusive.  If the
Guarantor is entitled to notice, that requirement is met if the Bank sends
notice at least seven (7) days prior to the date of sale, disposition or
other event which requires notice.  The proceeds of any sale will be applied
first to costs, then toward payment of the amount owing under this
Agreement.  The Bank may cause all or any part of the Collateral to be
transferred to or registered in its name or in the name of any other person
or business entity, with or without designating the capacity of that
nominee.

        For purposes of the following paragraphs, "any collateral" shall
include the Guarantor's Collateral and any other collateral securing the
Liabilities.

NEGATIVE PLEDGE:  The Guarantor will not allow any lien to exist on any of
its property or any property belonging to any Borrower, except liens known
to the Bank and existing on the date of this Agreement and new liens which
in aggregate, total less than USD -------- or equivalent with respect to the
Guarantor and -------- or equivalent in the aggregate with respect to the
Borrowers.  Guarantor further agrees that it will not execute any agreement
containing a negative pledge clause with any other lender.

ACTION REGARDING BORROWER:  If any monies become available that the Bank can
apply to the Liabilities, the Bank may apply them in any manner it chooses,
including but not limited to applying them against liabilities which are not
covered by this Agreement.  The Bank may take any action against any
Borrower, any collateral, or any other person liable for any of the
Liabilities.  The Bank may release any Borrower or anyone else from the
Liabilities, either in whole or in part, or release any collateral, and need
not perfect a security interest in any collateral.  The Bank does not have
to exercise any rights that it has against any Borrower or anyone else, or
make any effort to realize on any collateral or right of set-off.  If any
borrower requests more credit or any other benefit, the Bank may grant it
and the Bank may grant renewals, extensions, modifications and amendments of
the Liabilities and otherwise deal with any Borrower or any other person as
the Bank sees fit and as if this Agreement were not in effect.

The Guarantor's obligations under this Agreement are not released or
affected by (a) any act or omission of the Bank, (b) the voluntary or
involuntary liquidation, sale or other disposition of all or substantially
all of the assets of the Borrower, (c) any receivership, insolvency,
bankruptcy, reorganization, or other similar proceedings affecting any
Borrower or any of its assets, (d) any change in the composition or
structure or any Borrower or Guarantor, including a merger or consolidation
with any other person or entity, or (e) the full or partial assignment of
any Liability.

NATURE OF GUARANTY:  This Agreement is a guaranty of payment and not of
collection.  Therefore, the Bank may insist that the Guarantor pay
immediately, and the Bank is not required to attempt to collect first from
the Borrower, any collateral, or any other person liable for the
Liabilities.  The obligation of the Guarantor is unconditional and absolute,
even if all or any part of any agreements between the Bank and the Borrower
is unenforceable, void voidable or illegal, and regardless of the existence
of any defense, setoff or counterclaim which the Borrower may assert.

OTHER GUARANTORS:  Any Guarantor's obligations under this Agreement are
joint and several with any other guarantor of the Liabilities.  If the Bank
elects to enforce its rights against less than all guarantors of the
Liabilities, that election does not release any Guarantor from its
obligations under this Agreement.  The compromise or release of any of the
obligations of any of the other guarantors or the Borrower does not serve to
waive, alter or release the Guarantor's obligations.

RIGHTS OF SUBROGATION:  The Guarantor will not enforce any rights of
subrogation, contribution or indemnification that it has against the
Borrower, any person liable on the Liabilities, or any collateral, until the
Borrower and the Guarantor have fully performed all their obligations to the
Bank, even if those obligations are not covered by this Agreement.  The
Guarantor further agrees that if all or any part of the payments to the Bank
on the Liabilities are invalidated, declared to be fraudulent or
preferential, set aside or required to be repaid to a trustee, receiver or
any other party under any bankruptcy act or code, state or federal law,
common law or equitable doctrine, then this Agreement and any Collateral
remain in full force and effect (or are reinstated as the case may be) until
payment in full of those amounts.  That payment is due on demand.

WAIVERS:  The Guarantor waives any right it may have to receive notice of
the following matters before the Bank enforces any of its rights: (i) the
Bank's acceptance of this Agreement,  (ii) any credit that the Bank extends
to the Borrower, (iii) the Borrower's default, (iv) any demand, (v) any
action that the Bank takes regarding the Borrower, anyone else, any
collateral, or any Liability, which it is entitled to by law or under any
other agreement.  Any waiver affects only the specific terms and time period
stated in the waiver.  The Bank may waive or delay enforcing any of its
rights without losing them.  No modification or waiver of this Agreement is
effective unless it is in writing and signed by the party against whom it is
being enforced.

REPRESENTATIONS BY GUARANTOR:  Each Guarantor represents that:  (a) the
execution and delivery of this Agreement and the performance of the
obligations it imposes do not violate any law, conflict with any agreement
by which it is bound, or require the consent or approval of any governmental
authority or any third party; (b) this Agreement is a valid and binding
agreement enforceable according to its terms; and (c) all balance sheets,
profit and loss statements, and other financial statements furnished to the
Bank are accurate and fairly reflect the financial condition of the
organizations and persons to which they apply on their effective dates,
including contingent liabilities of every type, which financial condition
has not changed materially and adversely since those dates.  Each Guarantor,
other than a natural person, further represents that: (a) it is duly
organized, existing and in good standing under the laws where it is
organized; and (b) the execution and delivery of this note and the
performance of the obligations it imposes (i) are within its powers; (ii)
have been duly authorized by all necessary action of its governing body; and
(iii) do not contravene the terms of its articles of incorporation or
organization, its by-laws or any agreement governing its affairs.

NOTICES:  Notice from one party to another relating to this Agreement is
effective if made in writing (including telecommunications) and delivered to
the recipients address, telex number or facsimile number set forth under its
name by any of the following means: (a) hand delivery, (b) registered or
certified mail, postage prepaid, with return receipt requested, (c) first
class or express mail, postage prepaid, (d) Federal Express, Purolator
Courier or like overnight courier service, or (e) telex, facsimile or other
wire transmission with request for assurance of receipt in a manner typical
with respect to communications of that type.  Notice made in accordance with
this section is deemed delivered on receipt if delivered by hand or wire
transmission, on the third business day after mailing by first class,
registered or certified mail or on the next business day after mailing or
deposit with an overnight courier service.

LAW AND JUDICIAL FORUM THAT APPLY:  This Agreement is governed by Michigan
law.  The Guarantor agrees that any legal action or proceeding against it
with respect to any of its obligations under this Agreement may be brought
in any court of the State of Michigan or of the United States of America for
the Eastern or Western District of Michigan, as the Bank in its sole
discretion elects.  By the execution and delivery of this Agreement, the
Guarantor submits to and accepts the jurisdiction of those courts with
regard to any action or proceeding, for itself and in respect of its
property, generally and unconditionally, and agrees that service of process
pursuant to the NOTICE section, or pursuant to court rule, will grant
personal jurisdiction over the Guarantor to that court.  The Guarantor
waives any claim that the State of Michigan is not a convenient forum or the
proper venue for any suit, action or proceeding.

FOREIGN CURRENCY:  The specification of payment in a specific place and time
pursuant to the documentation relating to the Liabilities is essential. 
That currency or those currencies are also the currency of account and
payment under this Agreement.  In the event that any payment, whether
pursuant to a judgment or otherwise, does not result in payment of the
amount of currency due under this Agreement upon conversion to the currency
of account and transfer to the place specified for payment, the Bank has an
independent cause of action against the Guarantor for the deficiency.

MISCELLANEOUS:  The Guarantor's liability under this Agreement is
independent of its liability under any other guaranty previously or
subsequently executed by the Guarantor or any one of them, singularly or
together with others, as to all or any part of the Liabilities, and may be
enforced for the full amount of this Agreement regardless of the Guarantor's
liability under any other guaranty.  This Agreement binds the Guarantor's
heirs, successors and assigns, and benefits the Bank and its successors and
assigns.  The use of headings does not limit the provisions of this
Agreement.  

WAIVER OF JURY TRIAL:  The Bank and the Guarantor, after consulting or
having had the opportunity to consult with counsel, knowingly, voluntarily
and intentionally waive any right either of them has to a trial by jury in
any litigation based on or arising out of this Agreement or any related
instrument or agreement, or any of the transactions implied by this
Agreement, or any course of conduct, dealing, statements (whether oral or
written), or actions of either of them.  Neither the Bank nor the Guarantor
may seek to consolidate, by counterclaim or otherwise, any 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 may not be modified in
any respect or relinquished by either the Bank or any Guarantor except by a
written instrument executed by all of them.

            CONTINUING GUARANTY AND INDEMNITY FOR INTERNATIONAL CREDITS
                          (For U.S. Resident Guarantors)

GUARANTY:  To induce NBD Bank of 611 Woodward Avenue, Detroit, Michigan
48226, directly or through any of its affiliates including The First
National Bank of Chicago, acting through any of their respective branch
offices, subsidiaries or affiliates (the "Bank"), at its option, to make
loans, extend or continue credit or some other transaction, including
letters of credit and foreign exchange contracts, present or future, direct
and indirect, and whether several, joint or joint and several (referred to
collectively as "Liabilities"), to Interface Systems International, Ltd.,
and its their successors (the "Borrowers"), and because the undersigned (the
"Guarantor") has determined that executing this Guaranty is in its interest
and to its financial benefit, the Guarantor absolutely and unconditionally
guarantees to the Bank, a primary obligor and not merely as surety, that the
Liabilities will be paid when due, whether by acceleration or otherwise, in
accordance with the terms and conditions of the documentation related to the
Liabilities.  The Guarantor will not only pay the Liabilities, but will also
reimburse the Bank for accrued and unpaid interest, taxes and any expenses,
including reasonable attorneys' fees, that the Bank may pay in relation to
the Liabilities or this Agreement, and for liquidating any collateral.

INDEMNITY:  As an additional and continuing obligation, the Guarantor
independently, unconditionally and irrevocably agrees that, should the
Liabilities not be recoverable from the Guarantor under the preceding
paragraph for any reason whatsoever, the Guarantor will on demand pay the
Bank in the currency and otherwise as provided in the documentation for the
Liabilities, the outstanding balance of the Liabilities, including accrued
and unpaid interest, taxes and expenses, including reasonable attorneys'
fees, that the Bank may pay in relation to the Liabilities or this
Agreement, and for liquidating any collateral, by way of a full indemnity.

NO DEDUCTION:  All payments of the Liabilities will be made by the Guarantor
without deduction for or on account of any present or future charges of
whatever nature imposed by any governmental authority.  If those charges are
imposed, the Guarantor will pay them in addition to paying the Liabilities
as required by this Agreement, and will furnish certified copies of all
official receipts evidencing payment of the charges to the Bank within 45
days after their due date.

LIMITATION:  [The Guarantor's obligation under this Agreement is UNLIMITED.] 
[Regardless of the amount of Liabilities outstanding at any time, the
Guarantor's obligation under this Agreement does not exceed the principal
amount of    N/A  (       ) the amount(s) reflected in Exhibit A, plus
interest, expenses, and fees.]

CONTINUED RELIANCE:  The Bank may continue to make loans or extend credit to
the Borrower based on this Agreement until it receives written notice of
termination from the Guarantor.  That notice shall be effective at the
opening of the Bank on the first business day following receipt of the
notice at the address specified above.  If terminated, the Guarantor will
continue to be liable to the Bank for any Liabilities created, assumed or
committed to at the time the termination becomes effective, and all
subsequent renewals, extensions, modifications and amendments of those
Liabilities.

SECURITY:  As security for this Agreement, the Guarantor pledges and grants
to the Bank a continuing security interest in the property described below
and all of its additions, substitutions, increments, proceeds and products,
whether now owned or later acquired (the "Collateral"):

1.      All securities and other property of the Guarantor in the custody,
possession or control of the Bank's Commercial Loan Department except
property held in a fiduciary capacity.

2.      All property or securities declared or acknowledged to constitute
security for any past, present or future liability, direct or indirect, of
the Guarantor to the Bank;

3.      All balances of deposit accounts of the Guarantor with the Bank.

4.      The following additional property of the Guarantor:  accounts
receivable, inventory, machinery and equipment.

The Bank has the right at any time to apply its own debt or liability to the
Guarantor in whole or partial payment or this Agreement or other present or
future liabilities of the Guarantor to the Bank, direct or indirect, without
any requirement of mutual maturity.

INCORPORATION:  The Guarantor agrees that so long as any Liability remains
outstanding, it will observe, for the benefit of the Bank, the covenants and
events of default set forth in the Credit Authorization Agreement dated
February 19, 1997 between NBD Bank and the Guarantor, as amended (the
"Credit Agreement"), which are incorporated by reference.  Those covenants
and events of default shall remain in force until this Guaranty is no longer
in force, notwithstanding any termination of the Credit Agreement.

EVENTS OF DEFAULT/ACCELERATION:  The Bank has the right to terminate any
commitment to extend credit or complete other transactions with any
Borrower, and demand payment under this Agreement whether or not all of any
part of the Liabilities have matured, if any of the following events occurs:

1.      Any Guarantor or Borrower fails to pay when due any amount payable
under this Agreement or under any agreement or instrument evidencing debt to
any creditor.

2.      Any Guarantor or Borrower (i) fails to observe or perform any term of
this Agreement or the Liabilities; (ii) makes any materially incorrect or
misleading representation, warranty, or certificate to the Bank (iii) makes
any materially incorrect or misleading representation in any financial
statement or other information delivered to the Bank; or (iv) defaults under
the terms of any agreement or instrument relating to any debt for borrowed
money (other than the debt evidenced by this Agreement), including any
capitalized lease obligation, such that the creditor declares the debt due
before its maturity.

3.      There is a default under the terms of any loan agreement, mortgage,
security agreement, or any other document executed as part of any loan by
any Borrower or Guarantor from any creditor, or any guarantor fails to
promptly perform under its guaranty.

4.      A "reportable event" (as defined in the Employee Retirement Income
Security Act of 1974 as amended) occurs that would permit the Pension
Benefit Guaranty Corporation to terminate any employee benefit plan of any
Guarantor or Borrower or any affiliate of any Guarantor or Borrower, or if
any of them becomes subject to any multi-employer plan.

5.      Any Guarantor or Borrower becomes insolvent or unable to pay its
debts as they become due.

6.      Any Guarantor or Borrower (i) makes an assignment for the benefit of
creditors; (ii) consents to the appointment of a custodian, receiver, or
trustee for itself or for a substantial part of its assets; or (iii)
commences any proceeding under any bankruptcy, reorganization, liquidation,
insolvency or similar laws of any jurisdiction.

7.      A custodian, receiver or trustee is appointed for any Guarantor or
Borrower or for a substantial part of its assets without its consent, and is
not removed within 60 days after the appointment.

8.      Proceedings are commenced against any Guarantor or Borrower under any
bankruptcy, reorganization, liquidation, insolvency or similar laws of any
jurisdiction, and they remain dismissed for 60 days after commencement; or
any Guarantor or Borrower consents to the commencement of those proceedings.

9.      Any judgment is entered against any Guarantor or Borrower, or any
attachment, levy, or garnishment is issued against any property of any
Guarantor or Borrower, where the USD equivalent of the claim exceeds $ N/A.

10.     Any Guarantor or Borrower dies.

11.     Any Guarantor or Borrower, without the Bank's written consent, (i) is
dissolved, (ii) merges or consolidates with any third party, (iii) leases,
sells or otherwise conveys a material part of its assets or business outside
the ordinary course of business, (iv) leases, purchases or otherwise
acquires a material part of the assets of any other corporation or business
entity except in the ordinary course of such business, or (v) agrees to do
any of the foregoing.

12.     The loan-to-value ratio of any pledged securities at any time exceeds
N/A % and that excess continues for five (5) days after notice from the Bank
to any Guarantor.

13.     There is a substantial change in the existing or prospective
financial condition of any Guarantor or Borrower which the Bank in good
faith determines to be materially adverse.

14.     The Bank in good faith deems itself insecure.

REMEDIES ON DEFAULT:  In addition, the Bank has all of the rights and
remedies provided by law or under any other agreement to liquidate or
foreclose on and sell the Collateral, including but not limited to the
rights and remedies of a secured part under the Uniform Commercial Code. 
These rights and remedies are cumulative and not exclusive.  If the
Guarantor is entitled to notice, that requirement is met if the Bank sends
notice at least seven (7) days prior to the date of sale, disposition or
other event which requires notice.  The proceeds of any sale will be applied
first to costs, then toward payment of the amount owing under this
Agreement.  The Bank may cause all or any part of the Collateral to be
transferred to or registered in its name or in the name of any other person
or business entity, with or without designating the capacity of that
nominee.

        For purposes of the following paragraphs, "any collateral" shall
include the Guarantor's Collateral and any other collateral securing the
Liabilities.

NEGATIVE PLEDGE:  The Guarantor will not allow any lien to exist on any of
its property or any property belonging to any Borrower, except liens known
to the Bank and existing on the date of this Agreement and new liens which
in aggregate, total less than USD NA or equivalent with respect to the
Guarantor and --NA------ or equivalent in the aggregate with respect to the
Borrowers.  Guarantor further agrees that it will not execute any agreement
containing a negative pledge clause with any other lender.

ACTION REGARDING BORROWER:  If any monies become available that the Bank can
apply to the Liabilities, the Bank may apply them in any manner it chooses,
including but not limited to applying them against liabilities which are not
covered by this Agreement.  The Bank may take any action against any
Borrower, any collateral, or any other person liable for any of the
Liabilities.  The Bank may release any Borrower or anyone else from the
Liabilities, either in whole or in part, or release any collateral, and need
not perfect a security interest in any collateral.  The Bank does not have
to exercise any rights that it has against any Borrower or anyone else, or
make any effort to realize on any collateral or right of set-off.  If any
borrower requests more credit or any other benefit, the Bank may grant it
and the Bank may grant renewals, extensions, modifications and amendments of
the Liabilities and otherwise deal with any Borrower or any other person as
the Bank sees fit and as if this Agreement were not in effect.

The Guarantor's obligations under this Agreement are not released or
affected by (a) any act or omission of the Bank, (b) the voluntary or
involuntary liquidation, sale or other disposition of all or substantially
all of the assets of the Borrower, (c) any receivership, insolvency,
bankruptcy, reorganization, or other similar proceedings affecting any
Borrower or any of its assets, (d) any change in the composition or
structure or any Borrower or Guarantor, including a merger or consolidation
with any other person or entity, or (e) the full or partial assignment of
any Liability.

NATURE OF GUARANTY:  This Agreement is a guaranty of payment and not of
collection.  Therefore, the Bank may insist that the Guarantor pay
immediately, and the Bank is not required to attempt to collect first from
the Borrower, any collateral, or any other person liable for the
Liabilities.  The obligation of the Guarantor is unconditional and absolute,
even if all or any part of any agreements between the Bank and the Borrower
is unenforceable, void voidable or illegal, and regardless of the existence
of any defense, setoff or counterclaim which the Borrower may assert.

OTHER GUARANTORS:  Any Guarantor's obligations under this Agreement are
joint and several with any other guarantor of the Liabilities.  If the Bank
elects to enforce its rights against less than all guarantors of the
Liabilities, that election does not release any Guarantor from its
obligations under this Agreement.  The compromise or release of any of the
obligations of any of the other guarantors or the Borrower does not serve to
waive, alter or release the Guarantor's obligations.

RIGHTS OF SUBROGATION:  The Guarantor will not enforce any rights of
subrogation, contribution or indemnification that it has against the
Borrower, any person liable on the Liabilities, or any collateral, until the
Borrower and the Guarantor have fully performed all their obligations to the
Bank, even if those obligations are not covered by this Agreement.  The
Guarantor further agrees that if all or any part of the payments to the Bank
on the Liabilities are invalidated, declared to be fraudulent or
preferential, set aside or required to be repaid to a trustee, receiver or
any other party under any bankruptcy act or code, state or federal law,
common law or equitable doctrine, then this Agreement and any Collateral
remain in full force and effect (or are reinstated as the case may be) until
payment in full of those amounts.  That payment is due on demand.

WAIVERS:  The Guarantor waives any right it may have to receive notice of
the following matters before the Bank enforces any of its rights: (i) the
Bank's acceptance of this Agreement,  (ii) any credit that the Bank extends
to the Borrower, (iii) the Borrower's default, (iv) any demand, (v) any
action that the Bank takes regarding the Borrower, anyone else, any
collateral, or any Liability, which it is entitled to by law or under any
other agreement.  Any waiver affects only the specific terms and time period
stated in the waiver.  The Bank may waive or delay enforcing any of its
rights without losing them.  No modification or waiver of this Agreement is
effective unless it is in writing and signed by the party against whom it is
being enforced.

REPRESENTATIONS BY GUARANTOR:  Each Guarantor represents that:  (a) the
execution and delivery of this Agreement and the performance of the
obligations it imposes do not violate any law, conflict with any agreement
by which it is bound, or require the consent or approval of any governmental
authority or any third party; (b) this Agreement is a valid and binding
agreement enforceable according to its terms; and (c) all balance sheets,
profit and loss statements, and other financial statements furnished to the
Bank are accurate and fairly reflect the financial condition of the
organizations and persons to which they apply on their effective dates,
including contingent liabilities of every type, which financial condition
has not changed materially and adversely since those dates.  Each Guarantor,
other than a natural person, further represents that: (a) it is duly
organized, existing and in good standing under the laws where it is
organized; and (b) the execution and delivery of this note and the
performance of the obligations it imposes (i) are within its powers; (ii)
have been duly authorized by all necessary action of its governing body; and
(iii) do not contravene the terms of its articles of incorporation or
organization, its by-laws or any agreement governing its affairs.

NOTICES:  Notice from one party to another relating to this Agreement is
effective if made in writing (including telecommunications) and delivered to
the recipients address, telex number or facsimile number set forth under its
name by any of the following means: (a) hand delivery, (b) registered or
certified mail, postage prepaid, with return receipt requested, (c) first
class or express mail, postage prepaid, (d) Federal Express, Purolator
Courier or like overnight courier service, or (e) telex, facsimile or other
wire transmission with request for assurance of receipt in a manner typical
with respect to communications of that type.  Notice made in accordance with
this section is deemed delivered on receipt if delivered by hand or wire
transmission, on the third business day after mailing by first class,
registered or certified mail or on the next business day after mailing or
deposit with an overnight courier service.

LAW AND JUDICIAL FORUM THAT APPLY:  This Agreement is governed by Michigan
law.  The Guarantor agrees that any legal action or proceeding against it
with respect to any of its obligations under this Agreement may be brought
in any court of the State of Michigan or of the United States of America for
the Eastern or Western District of Michigan, as the Bank in its sole
discretion elects.  By the execution and delivery of this Agreement, the
Guarantor submits to and accepts the jurisdiction of those courts with
regard to any action or proceeding, for itself and in respect of its
property, generally and unconditionally, and agrees that service of process
pursuant to the NOTICE section, or pursuant to court rule, will grant
personal jurisdiction over the Guarantor to that court.  The Guarantor
waives any claim that the State of Michigan is not a convenient forum or the
proper venue for any suit, action or proceeding.

FOREIGN CURRENCY:  The specification of payment in a specific place and time
pursuant to the documentation relating to the Liabilities is essential. 
That currency or those currencies are also the currency of account and
payment under this Agreement.  In the event that any payment, whether
pursuant to a judgment or otherwise, does not result in payment of the
amount of currency due under this Agreement upon conversion to the currency
of account and transfer to the place specified for payment, the Bank has an
independent cause of action against the Guarantor for the deficiency.

MISCELLANEOUS:  The Guarantor's liability under this Agreement is
independent of its liability under any other guaranty previously or
subsequently executed by the Guarantor or any one of them, singularly or
together with others, as to all or any part of the Liabilities, and may be
enforced for the full amount of this Agreement regardless of the Guarantor's
liability under any other guaranty.  This Agreement binds the Guarantor's
heirs, successors and assigns, and benefits the Bank and its successors and
assigns.  The use of headings does not limit the provisions of this
Agreement.  

WAIVER OF JURY TRIAL:  The Bank and the Guarantor, after consulting or
having had the opportunity to consult with counsel, knowingly, voluntarily
and intentionally waive any right either of them has to a trial by jury in
any litigation based on or arising out of this Agreement or any related
instrument or agreement, or any of the transactions implied by this
Agreement, or any course of conduct, dealing, statements (whether oral or
written), or actions of either of them.  Neither the Bank nor the Guarantor
may seek to consolidate, by counterclaim or otherwise, any 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 may not be modified in
any respect or relinquished by either the Bank or any Guarantor except by a
written instrument executed by all of them.
