                          SECOND AMENDED AND RESTATED
                          REVOLVING CREDIT AGREEMENT


     THIS SECOND AMENDED AND RESTATED CREDIT AGREEMENT, made as of the 31st day
of October, 1997, by and between Cade Industries, Inc., a Wisconsin corporation,
of Lansing, Michigan ("Company"), and COMERICA Bank, a Michigan banking
corporation, of Detroit, Michigan (herein called "Bank");

     RECITALS:

     A.   Company and Bank entered into an Amended and Restated Revolving Credit
and Term Loan Agreement dated as of January 30, 1995 (the "Existing Agreement").

     B.   Company and Bank desire to amend and restate the Existing Agreement in
its entirety.

     NOW, THEREFORE, Company and Bank agree that the Existing Agreement is
amended and restated in its entirety as follows:

     WITNESSETH:

     1.A  THE INDEBTEDNESS: LINE OF CREDIT

     1.A.1  Bank may lend to Company at any time and from time to time from the
effective date hereof until April 1, 1999 sums not to exceed Nine Million
Dollars ($9,000,000) in aggregate principal amount at any one time outstanding.
The borrowings hereunder shall be evidenced by a Line of Credit Note (herein
called "Line Note") in form similar to that annexed hereto as Exhibit "A" under
which advances, repayments and readvances may be made, subject to the terms and
conditions of this Agreement; provided, however, the Bank shall have no
obligation to make any advances with respect to the line of credit.

     1.A.2  The principal indebtedness represented by the Line Note and all
interest thereon shall be payable in accordance with the terms of the Line Note.

     1.A.3  Bank shall not lend under the Line Note unless Company shall have
first filed with Bank a Request for Advance (as of the 
<PAGE>
 
date of the borrowing) in form similar to that annexed hereto as Exhibit "B",
executed by an authorized officer of the Company. Bank may, at its option, lend
under the Line Note upon the telephone request of an authorized employee of the
Company and, in the event Bank makes any such advance upon a telephone request,
the requesting employee shall, if requested by Bank, mail to Bank, on the same
day as such telephone request, a Request for Advance in the form attached as
Exhibit "B".

     1.A.4  In addition to advances under the Line Note to be provided to
Company by Bank under and pursuant to Section 1.A.1 of this Agreement, Bank may
issue, or commit to issue, from time to time, standby and trade letters of
credit for the account of Company (herein individually called a "Letter of
Credit" and collectively "Letters of Credit") and enter into foreign exchange
contracts where the total exposure of Bank (as calculated by Bank) does not
exceed Two Million Five Hundred Thousand Dollars ($2,500,000) at any one time in
the aggregate for a Letter of Credit and One Million Dollars ($1,000,000);
provided, however that the sum of the aggregate amount of advances outstanding
under the Line Note plus the undrawn amount of the Letters of Credit (and
unreimbursed drawings thereunder) and foreign exchange exposure shall not exceed
Nine Million Dollars ($9,000,000.00) at any one time; and provided further that
no Letter of Credit shall, by its terms, have an expiration date which extends
beyond April 1,1999. In addition to the terms and conditions of this Agreement,
the issuance of any Letters of Credit shall also be subject to the terms and
conditions of any letter of credit applications and agreements executed and
delivered by Company unto Bank with respect thereto.

     1.A.5  Company may prepay the Line Note in accordance with the terms of the
Line Note.

     2.   TERM CREDIT-A

     2.1  Bank agrees to loan to Company and Company agrees to borrow, on the
date of execution of this Agreement, the sum of Three Million Five Hundred
Seventy One Thousand Four Hundred Twenty Eight and 56/100 Dollars
($3,571,428.56). At the time of borrowing, Company agrees to execute a term note
in form similar to that annexed hereto as Exhibit "C" as evidence of the
indebtedness hereunder (herein called "Term Note-A"). The loan under this

                                       3
<PAGE>
 
Section 2 shall be subject to the terms and conditions of this Agreement.

     2.2  The indebtedness represented by the Term Note-A shall be repaid in
quarterly principal installments of One Hundred Seventy Eight Thousand Five
Hundred Seventy One and 43/100 Dollars ($178,571.43) each, plus interest as set
forth below, commencing on January 1, 1998, and on the 1st day of each
succeeding calendar quarter, until November 1, 2002, when the entire unpaid
balance of principal and interest thereon shall be due and payable. Company
agrees to pay interest on the unpaid principal balance of the Term Note-A from
time to time outstanding at a per annum rate of eight and nineteen one
hundredths percent (8.19%). Upon the occurrence of any default or event of
default hereunder, interest shall accrue on the unpaid principal balance at a
per annum rate equal to the greater of (i) eleven and nineteen one hundredths
percent (11.19%) and three percent (3%) above Bank's Prime Rate. Interest shall
be computed on a daily basis using a year of 360 days and assessed for the
actual number of days elapsed, and in such computation effect shall be given to
any change in the interest rate resulting from a change in the Prime Rate on the
date of such change in the Prime Rate. "Prime Rate" shall mean the rate of
interest established by Bank as its prime rate as the same may be changed from
time to time, which may not necessarily be Bank's lowest rate for loans.

     A late installment charge equal to five percent (5%) of each late
installment may be charged on any installment payment not received by Bank
within ten (10) calendar days after the installment due date but acceptance of
this charge shall not waive any default or event of default under this
Agreement.

     2.3  All partial prepayments with respect to the Term Note-A shall be
applied to the Term Note-A in the inverse order of their respective maturities.
The Term Note-A may be prepaid on any principal installment payment date upon
five (5) days written notice to Bank, in whole or in part (in amounts of at
least $100,000) upon payment of a premium equal to the sum of the discounted net
present values of the interest payments that would otherwise be payable on the
principal amount being prepaid, after reducing each such interest payment by the
amount of the interest that would be payable on each interest payment due date
if the principal amount being prepaid were re-invested at the Current Market
Rate therefor plus $500. For these purposes, "Current Market 

                                       4
<PAGE>
 
Rate" shall mean a per annum interest rate equal to one half percent (1/2%)
above the rate reasonably determined by Bank (based on quotations from
established dealers) to be in effect approximately two days prior to the
repayment date in the secondary market for United States Treasury securities of
a comparable amount and with a comparable term to maturity as the principal
amount being prepaid. For the purposes of computation, the discount rate for
each computation will be the Current Market Rate for the relevant principal
installment. Upon any involuntary prepayment of the Term Note-A, Company shall
pay to Bank a prepayment premium equal to the prepayment premium which would be
due and payable hereunder if Company had voluntarily elected to prepay the Term
Note-A (in an amount equal to such involuntary prepayment) on such date of
involuntary prepayment.

     2.4  The proceeds of the Term Note-A shall be used solely to fund a portion
of the purchase price payable by Company under the terms of the Stock Purchase
Agreement dated as of October 31, 1997 by and among Company and the shareholders
of Central Engineering Company ("Stock Purchase Agreement") and to refinance
Company's existing term debt with Bank.

     3.   TERM CREDIT-B

     3.1  Bank agrees to loan to Company and Company agrees to borrow, on the
date of execution of this Agreement, the sum of Four Million Dollars
($4,000,000). At the time of borrowing, Company agrees to execute a term note in
form similar to that annexed hereto as Exhibit "D" as evidence of the
indebtedness hereunder (herein called "Term Note-B"). The loan under this
Section 3 shall be subject to the terms and conditions of this Agreement.

     3.2  The indebtedness represented by the Term Note-B shall be repaid in
quarterly principal and interest installments of One Hundred Eighteen Thousand
Six Hundred Twenty Four and 08/100 Dollars ($118,624.08) each, commencing on
January 1, 1998, and on the 1st day of each succeeding calendar quarter, until
November 1, 2002, when the entire unpaid balance of principal and interest
thereon shall be due and payable. Company agrees to pay interest on the unpaid
principal balance of the Term Note-B from time to time outstanding at a per
annum rate of one half percent (1/2%) below Bank's Prime Rate. Interest shall be
payable quarterly on the 1st day of each calendar quarter commencing January 1,
1998. Upon the 

                                       5
<PAGE>
 
occurrence of any default or event of default hereunder, interest shall accrue
on the unpaid principal balance at a per annum rate equal to two and one half
percent (2-1/2%) above the Prime Rate. Interest shall be computed on a daily
basis using a year of 360 days and assessed for the actual number of days
elapsed, and in such computation effect shall be given to any change in the
interest rate resulting from a change in the Prime Rate on the date of such
change in the Prime Rate.

     The installment payments are calculated at an assumed fixed interest rate
and an assumed fifteen year amortization term. In the event the Bank's prime
rate changes, the Bank, at its sole option, may from time to time recalculate
the period installment amount so that the remaining periodic installments will
fully amortize the remaining loan balance within the remaining amortization term
in equal installments at the interest rate then being charged under Term Note-B.
COMPANY AGREES TO PAY THE PERIODIC INSTALLMENTS AS THEY MAY BE RECALCULATED BY
THE BANK, AT THE BANK'S SOLE OPTION, FROM TIME TO TIME AND ACKNOWLEDGES THAT A
RECALCULATION SHALL NOT AFFECT THE MATURITY DATE OR THE OTHER TERMS AND
PROVISIONS OF TERM NOTE-B.

     A late installment charge equal to five percent (5%) of each late
installment may be charged on any installment payment not received by Bank
within ten (10) calendar days after the installment due date but acceptance of
this charge shall not waive any default or event of default under this
Agreement.

     3.3  Company may prepay the Term Note-B in whole or in part without premium
or penalty.

     3.4  The proceeds of the Term Note-B shall be used solely to fund a portion
of the purchase price payable by Company under the terms of the Stock Purchase
Agreement.

     4.   TERM CREDIT-C

     4.1  Bank agrees to loan to Company and Company agrees to borrow, on the
date of execution of this Agreement, the sum of Three Million Two Hundred Fifty
Thousand Dollars ($3,250,000). At the time of borrowing, Company agrees to
execute a term note in form similar to that annexed hereto as Exhibit "E" as
evidence of the indebtedness hereunder (herein called "Term Note-C and together

                                       6
<PAGE>
 
with the Line Note, Term Note-A and Term Note-B, the "Notes"). The loan under
this Section 4 shall be subject to the terms and conditions of this Agreement.
     
     4.2  The indebtedness represented by the Term Note-C shall be repaid in
quarterly principal installments of Two Hundred Seventy Thousand Eight Hundred
Thirty Three and 33/100 Dollars ($270,833.33) each, plus interest as set forth
below, commencing on January 1, 1998, and on the 1st day of each succeeding
calendar quarter, until November 1, 2000, when the entire unpaid balance of
principal and interest thereon shall be due and payable. Company agrees to pay
interest on the unpaid principal balance of the Term Note-C from time to time
outstanding at a per annum rate of eight and six one hundredths percent (8.06%)
until November 1, 1999 when the interest rate shall be a per annum rate equal to
one half of one percent (1/2%) below Bank's Prime Rate. Upon the occurrence of
any default or event of default hereunder, interest shall accrue on the unpaid
principal balance at a per annum rate equal to the greater of (i) eleven and six
one hundredths percent (11.06%) and three percent (3%) above Bank's Prime Rate.
Interest shall be computed on a daily basis using a year of 360 days and
assessed for the actual number of days elapsed, and in such computation effect
shall be given to any change in the interest rate resulting from a change in the
Prime Rate on the date of such change in the Prime Rate.

     A late installment charge equal to five percent (5%) of each late
installment may be charged on any installment payment not received by Bank
within ten (10) calendar days after the installment due date but acceptance of
this charge shall not waive any default or event of default under this
Agreement.

     4.3  All partial prepayments with respect to the Term Note-C shall be
applied to the Term Note-A in the inverse order of their respective maturities.
While the interest rate is a fixed rate, the Term Note-C may be prepaid on any
principal installment payment date upon five (5) days written notice to Bank, in
whole or in part (in amounts of at least $100,000) upon payment of a premium
equal to the sum of the discounted net present values of the interest payments
that would otherwise be payable on the principal amount being prepaid, after
reducing each such interest payment by the amount of the interest that would be
payable on each interest payment due date if the principal amount being prepaid
were re-

                                       7
<PAGE>
 
invested at the Current Market Rate therefor plus $500. For these purposes,
"Current Market Rate" shall mean a per annum interest rate equal to one half
percent (1/2/0) above the rate reasonably determined by Bank (based on
quotations from established dealers) to be in effect approximately two days
prior to the repayment date in the secondary market for United States Treasury
securities of a comparable amount and with a comparable term to maturity as the
principal amount being prepaid. For the purposes of computation, the discount
rate for each computation will be the Current Market Rate for the relevant
principal installment. Upon any involuntary prepayment of the Term Note-C,
Company shall pay to Bank a prepayment premium equal to the prepayment premium
which would be due and payable hereunder if Company had voluntarily elected to
prepay the Term Note-C (in an amount equal to such involuntary prepayment) on
such date of involuntary prepayment. At all times when the interest rate is a
floating rate, the Term Note-C may be prepaid in the manner set forth in Section
3.3.

     4.4  The proceeds of the Term Note-C shall be used solely to fund a portion
of the purchase price payable by Company under the terms of the Stock Purchase
Agreement.

     5.   INTEREST RATE REDUCTION.

     5.1  The interest rates with respect to the Line Note and any other Note
which bears interest at a floating rate shall be reduced by one quarter of one
percent (1/4%) per annum at all times while the following conditions shall have
been satisfied by Company:

          (a) The ratio of Debt to Tangible Net Worth is equal to or less than
              1.5 to 1.0;

          (b) The Leverage Ratio is equal to or less than 2.5 to 1.0 and

          (c) The after tax profit for Company and its consolidated subsidiaries
              for two consecutive years (beginning with the year ending December
              31, 1997) are $2,000,000 or more per year.

     5.2  The determination of whether the conditions for reduction have been
satisfied shall be determined based on Company's 

                                       8
<PAGE>
 
quarterly and year end financial statements and shall be adjusted as of the
first day of the first month following the delivery of such financial statements
indicating that an adjustment to the interest rates is applicable.

     6.   CONDITIONS

appropriate corporate resolutions in certified form authorizing same, the
following:

          (a) Guaranty Agreements from Cade Composites, Inc., Auto-Air
              Composites, Inc., Pollux Acquisition Corporation, H.A.C.
              Corporation Cade, International, Inc. and Cade Commercial
              Composites, Inc., Central Engineering Company, Central Engineering
              International Co. and Cenco Europe, Inc. (collectively, the

execution of a new agreement or agreements.

evidence satisfactory to Bank of the consummation of the transactions described

           indebtedness hereunder or in any other collateral document related to
           or connected with this Agreement or the indebtedness hereunder, and
           continuation of such default beyond any period of grace specified in
           any such document;

     (e)   default in the payment of any other obligation of Company or any
           Guarantor for borrowed money in an amount in excess of One Hundred
           Thousand Dollars ($100,000), or in the observance or performance of
           any conditions, covenants or agreements related or given with respect
           thereto and, in each such case, continuance beyond any applicable
           cure period;

     (f)   judgments for the payment of money in excess of the sum of One
           Hundred Thousand Dollars ($100,000) in the aggregate shall be
           rendered against Company or any Guarantor, and such judgments shall
           remain unpaid, unvacated, unbonded or unstayed by appeal or otherwise
           for a period of sixty (60) consecutive days from the date of its
           entry;

     (g)   the occurrence of any "reportable event", as defined in the Employee
           Retirement Income Security Act of 1974 and any amendments thereto,
           which is determined to constitute grounds for termination by the
           Pension Benefit Guaranty Corporation of any employee pension benefit
           plan maintained by or on behalf of Company for the benefit of any of
           its employees or for the appointment by the appropriate United States
           District Court of a trustee to administer such plan and such

                                       25
<PAGE>
 
           reportable event is not corrected and such determination is not
           revoked within 30 days after notice thereof has been given to the
           plan administrator or Company; or the institution of proceeding by
           the Pension Benefit Guaranty Corporation to terminate any such
           employee benefit pension plan or to appoint a trustee to administer
           such plan; or the appointment of a trustee by the appropriate United
           States District Court to administer any such employee benefit pension
           plan;

     (h)   the revocation of any Guaranty or any guaranty by Company in favor of
           Bank of the obligations of any of its subsidiaries;

     (i)   default by Company in payment under any guaranty by Company in favor
           of Bank of the obligations of any of its subsidiaries;

then, or at any time thereafter, unless such default is first remedied, Bank may
give notice to Company declaring all outstanding indebtedness hereunder to be
due and payable, whereupon all indebtedness then outstanding hereunder shall
immediately become due and payable without further notice and demand, as the
case may be and Bank's commitment, if any, to make advances hereunder shall
automatically terminate.

     11.3  If a creditors' committee shall have been appointed for the business
of Company or any Guarantor; or if Company or any Guarantor shall have made a
general assignment for the benefit of creditors or shall have been adjudicated
bankrupt, or shall have filed a voluntary petition in bankruptcy or for
reorganization or to effect a plan or arrangement with creditors; or shall file
an answer to a creditor's petition or other petition filed against it, admitting
the material allegations thereof for an adjudication in bankruptcy or for
reorganization; or shall have applied for or permitted the appointment of a
receiver or trustee or custodian for any of its property or assets; or such
receiver, trustee or custodian shall have been appointed for any of its property
or assets (otherwise than upon application or consent of Company or any
Guarantor, as applicable) and such receiver, trustee, or custodian so appointed
shall not have been discharged within sixty (60) days after the date of his
appointment; or if an order shall

                                       26
<PAGE>
 
be entered and shall not be dismissed or stayed within sixty (60) days from its
entry, approving any petition for reorganization of Company or any Guarantor;
then the Notes and all indebtedness then outstanding hereunder shall
automatically become immediately due and payable and Bank's commitment, if any,
to make advances hereunder shall automatically terminate.

     11.4  Upon the occurrence and during the continuance of any Event of
Default, Company shall immediately upon demand by Bank deposit with Bank cash
collateral in the amount equal to the maximum amount available to be drawn at
any time under any Letter of Credit then outstanding.

                              LINE OF CREDIT NOTE
                               (Eurodollar Rate)


$9,000,000                                                     Detroit, Michigan
                                                                October 31, 1997



     On or before April 1, 1999 (herein called the "Maturity Date"), FOR VALUE
RECEIVED, the undersigned, Cade Industries, Inc., a Wisconsin corporation
(herein called "Borrower"), promises to pay to the order of COMERICA BANK, a
Michigan banking corporation (herein called "Bank"), in lawful currency of the
United States of America, the principal sum of NINE MILLION DOLLARS
($9,000,000), or so much of said sum as has been advanced and is then
outstanding under this Note, together with interest thereon as hereinafter set
forth.

     This Note is a note under which Advances, repayments and re-Advances may be
made from time to time, subject to the terms and conditions of this Note;
provided, however, in no event shall Bank be obligated to make any Advances or
re-Advances hereunder (notwithstanding anything expressed or implied herein or
elsewhere to the contrary).

     Each of the Advances made hereunder shall bear interest at the Eurodollar-
based Rate or the Prime-based Rate, as elected by Borrower or as otherwise
determined under this Note.

     Accrued and unpaid interest on the unpaid balance of each outstanding
Prime-based Advance shall be payable quarterly, in arrears, commencing on
January 1, 1998, and on the first Business Day of each succeeding quarter
thereafter, until maturity (whether as stated herein, by acceleration, or
otherwise). Interest accruing at the Prime-based Rate shall be computed on the
basis of a year of 
<PAGE>
 
360 days, and shall be assessed for the actual number of days elapsed, and in
such computation, effect shall be given to any change in the Applicable Interest
Rate as a result of any change in the Prime-based Rate on the date of each such
change in the Prime-based Rate.

     Accrued and unpaid interest on each Eurodollar-based Advance shall be
payable on the last day of the Interest Period applicable thereto (unless sooner
accelerated in accordance with the terms of this Note). Interest accruing at the
Eurodollar-based Rate shall be computed on the basis of a 360 day year and shall
be assessed for the actual number of days elapsed from the first day of the
Interest Period applicable thereto but not including the last day thereof.

     From and after the occurrence of any Default hereunder, and so long as any
such Default remains unremedied or uncured thereafter, the Indebtedness
outstanding under this Note shall bear interest at a per annum rate of three
percent (3%) above the otherwise Applicable Interest Rate, which interest shall
be payable upon demand.

     The amount and date of each Advance, its Applicable Interest Rate, its
Interest Period, if any, and the amount and date of any repayment shall be noted
on Bank's records, which records shall be conclusive evidence thereof, absent
manifest error; provided, however, any failure by Bank to make any such
notation, or any error in any such notation, shall not relieve Borrower of its
obligations to repay Bank all amounts payable by Borrower to Bank under or
pursuant to this Note, when due in accordance with the terms hereof.

     Borrower may request an Advance hereunder, including the refunding of an
outstanding Advance as the same type of Advance or the conversion of an
outstanding Advance as the same type of Advance, upon the delivery to Bank of a
Request for Advance executed by an authorized officer of Borrower, subject to
the following:

     (a) no Default, and no condition or event which, with the giving of notice
         or the running of time, or both, would constitute a Default, shall have
         occurred and be continuing or exist under this Note;

                                       2
<PAGE>
 
     (b) each such Request for Advance shall set forth the information required
         on the Request for Advance form annexed hereto as Exhibit "A";

     (c) each such Request for Advance shall be delivered to Bank by 11:00 a.m.
         (Detroit, Michigan time) one (l) Business Day prior to the proposed
         date of Advance in the case of Eurodollar-based Advances, and by 11:00
         a.m. (Detroit, Michigan time) on the proposed date of Advance in the
         case of Prime-based Advances;

     (d) the principal amount of each Eurodollar-based Advance shall be at least
         Five Hundred Thousand Dollars ($500,000);

     (e) the proposed date of any refunding of any outstanding Eurodollar-based
         Advance as another Eurodollar-based Advance or the conversion of any
         outstanding Eurodollar-based Advance to a Prime-based Advance shall
         only be on the last day of the Interest Period applicable to such
         outstanding Eurodollar-based Advance; and

     (f) a Request for Advance, once delivered to Bank, shall not be revocable
         by Borrower; provided, however, as aforesaid, Bank shall not be
         obligated to make any Advance under this Note.

     If, as to any outstanding Eurodollar-based Advance, Bank shall not receive
a timely Request for Advance in accordance with the foregoing requesting the
refunding of such Advance as a Eurodollar-based Advance, the principal amount of
such Advance which is not then repaid shall be automatically converted to a
Prime-based Advance on the last day of the Interest Period applicable thereto,
subject in all respects to the terms and conditions of this Note. The foregoing
shall not in any way whatsoever limit or otherwise affect any of Bank's rights
or remedies under this Note upon the occurrence of any Default hereunder, or any
condition or event which, with the giving of notice or the running of time, or
both, would constitute a Default.

     Borrower may prepay all or part of the outstanding balance of any Prime-
based Advance under this Note at any time. Borrower may prepay all or part of
any Eurodollar-based Advance on the last day 

                                       3
<PAGE>
 
of the Interest Period applicable thereto, provided that the aggregate balance
of Eurodollar-based Advances outstanding after such prepayment shall be at least
Five Hundred Thousand Dollars ($500,000), and the unpaid portion of such
Eurodollar-based Advance which is then refunded or converted shall be subject to
the limitations set forth in this Note. Any prepayment made in accordance with
this paragraph shall be without premium or penalty. Any other prepayment shall
be otherwise restricted by and subject to the terms of this Note.

     Subject to the definition of an "Interest Period" hereunder, in the event
that any payment under this Note becomes due and payable on any day which is not
a Business Day, the due date thereof shall be extended to the next succeeding
Business Day, and, to the extent applicable, interest shall continue to accrue
and be payable thereon during such extension at the rates set forth in this
Note.

     All payments to be made by Borrower to Bank under or pursuant to this Note
shall be in immediately available funds, without setoff or counterclaim, and in
the event that any payments submitted hereunder are in funds not available until
collected, said payments shall continue to bear interest until collected.
Borrower hereby authorizes Bank to charge any account of Borrower with Bank for
all sums due hereunder when due in accordance with the terms hereof.

     If Borrower makes any payment of principal with respect to any Eurodollar-
based Advance on any day other than the last day of the Interest Period
applicable thereto (whether voluntarily, by acceleration, or otherwise), or if
Borrower fails to borrow any Eurodollar-based Advance after notice has been
given by Borrower to Bank in accordance with the terms of this Note requesting
such Advance, or if Borrower fails to make any payment of principal or interest
in respect of a Eurodollar-based Advance when due, Borrower shall reimburse
Bank, on demand, for any resulting loss, cost or expense incurred by Bank as a
result thereof, including, without limitation, any such loss, cost or expense
incurred in obtaining, liquidating, employing or redeploying deposits from third
parties, whether or not Bank shall have funded or committed to fund such
Advance. Such amount payable by Borrower to Bank may include, without
limitation, an amount equal to the excess, if any, of (a) the amount of interest
which would have accrued on the 

                                       4
<PAGE>
 
amount so prepaid, or not so borrowed, refunded or converted, for the period
from the date of such prepayment or of such failure to borrow, refund or
convert, through the last day of the relevant Interest Period, at the applicable
rate of interest for said Advance(s) provided under this Note, over (b) the
amount of interest (as reasonably determined by Bank) which would have accrued
to Bank on such amount by placing such amount on deposit for a comparable period
with leading banks in the interbank eurodollar market. Calculation of any
amounts payable to Bank under this paragraph shall be made as though Bank shall
have actually funded or committed to fund the relevant Eurodollar-based Advance
through the purchase of an underlying deposit in an amount equal to the amount
of such Advance and having a maturity comparable to the relevant

     Interest Period; provided, however, that Bank may fund any Eurodollar-based
Advance in any manner it deems fit and the foregoing assumptions shall be
utilized only for the purpose of the calculation of amounts payable under this
paragraph. Upon the written request of Borrower, Bank shall deliver to Borrower
a certificate setting forth the basis for determining such losses, costs and
expenses, which certificate shall be conclusively presumed correct, absent
manifest error.

     For any Eurodollar-based Advance, if Bank shall designate a Eurodollar
Lending Office which maintains books separate from those of the rest of Bank,
Bank shall have the option of maintaining and carrying such Advance on the books
of such Eurodollar Lending Office.

     If, with respect to any Interest Period, Bank determines that, (a) by
reason of circumstances affecting the foreign exchange and interbank markets
generally, deposits in Eurodollars in the applicable amounts or for the relative
maturities are not being offered to Bank for such Interest Period, or (b) if the
rate of interest referred to in the definition of "Eurodollar based Rate" upon
the basis of which the rate of interest for a Eurodollar-based Advance is to be
determined does not accurately or fairly cover or reflect the cost to Bank of
making or maintaining a Eurodollar-based Advance hereunder, then Bank shall
forthwith give notice thereof to the Borrower. Thereafter, until Bank notifies
Borrower that such conditions or circumstances no longer exist, the right of
Borrower to request a Eurodollar-based Advance and to convert an 

                                       5
<PAGE>
 
Advance to or refund an Advance as a Eurodollar-based Advance shall be
suspended.

     If, after the date hereof, the introduction of, or any change in, any
applicable law, rule or regulation or in the interpretation or administration
thereof by any governmental authority charged with the interpretation or
administration thereof, or compliance by Bank (or its Eurodollar Lending Office)
with any request or directive (whether or not having the force of law) of any
such authority, shall make it unlawful or impossible for the Bank (or its
Eurodollar Lending Office) to make or maintain any Advance with interest at the
Eurodollar-based Rate, Bank shall forthwith give notice thereof to Borrower.
Thereafter, (a) until Bank notifies Borrower that such conditions or
circumstances no longer exist, the right of Borrower to request a Eurodollar-
based Advance and to convert an Advance to or refund an Advance as a Eurodollar-
based Advance shall be suspended, and thereafter, Borrower may select only the
Prime-based Rate as the Applicable Interest Rate hereunder, and (b) if Bank may
not lawfully continue to maintain an outstanding Advance to the end of the then
current Interest Period applicable thereto, the Prime based Rate shall be the
Applicable Interest Rate for the remainder of such Interest Period with respect
to such outstanding Advance.

     If the adoption after the date hereof, or any change after the date hereof
in, any applicable law, rule or regulation of any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by Bank (or its Eurodollar Lending Office)
with any request or directive (whether or not having the force of law) made by
any such authority, central bank or comparable agency after the date hereof:

     (a) shall subject Bank (or its Eurodollar Lending Office) to any tax, duty
         or other charge with respect to this Note or any Advance hereunder or
         shall change the basis of taxation of payments to Bank (or its
         Eurodollar Lending Office) of the principal of or interest on any
         Advance or any other amounts due under this Note in respect thereof
         (except for changes in the rate of tax on the overall net income of
         Bank or its Eurodollar Lending Office imposed by the jurisdiction in
         which Bank's principal executive office or Eurodollar Lending Office is
         located); or

                                       6
<PAGE>
 
     (b) shall impose, modify or deem applicable any reserve (including, without
         limitation, any imposed by the Board of Governors of the Federal
         Reserve System), special deposit or similar requirement against assets
         of, deposits with or for the account of, or credit extended by Bank (or
         its Eurodollar Lending Office) or shall impose on Bank (or its
         Eurodollar Lending Office) or the foreign exchange and interbank
         markets any other condition affecting any Advance under this Note;

and the result of any of the foregoing is to increase the cost to Bank of
maintaining any part of the indebtedness hereunder or to reduce the amount of
any sum received or receivable by Bank under this Note by an amount deemed by
the Bank to be material, then Borrower shall pay to Bank, within fifteen (15)
days of Borrower's receipt of written notice from Bank demanding such
compensation, such additional amount or amounts as will compensate Bank for such
increased cost or reduction. A certificate of Bank, prepared in good faith and
in reasonable detail by Bank and submitted by Bank to Borrower, setting forth
the basis for determining such additional amount or amounts necessary to
compensate Bank shall be conclusive and binding for all purposes, absent
manifest error in computation.

     In the event that any applicable law, treaty, rule or regulation (whether
domestic or foreign) now or hereafter in effect and whether or not presently
applicable to Bank, or any interpretation or administration thereof by any
governmental authority charged with the interpretation or administration
thereof, or compliance by Bank with any guideline, request or directive of any
such authority (whether or not having the force of law), including any risk-
based capital guidelines, affects or would affect the amount of capital required
or expected to be maintained by Bank (or any corporation controlling Bank), and
Bank determines that the amount of such capital is increased by or based upon
the existence of any obligations of Bank hereunder or the making or maintaining
any Advances hereunder, and such increase has the effect of reducing the rate of
return on Bank's (or such controlling corporation's) capital as a consequence of
such obligations or the making or maintaining of such Advances hereunder to a
level below that which Bank (or such controlling corporation) could have
achieved but for such circumstances (taking into consideration its policies with
respect to capital adequacy), then 

                                       7
<PAGE>
 
Borrower shall pay to Bank, within fifteen (15) days of Borrower's receipt of
written notice from Bank demanding such compensation, additional amounts as are
sufficient to compensate Bank (or such controlling corporation) for any increase
in the amount of capital and reduced rate of return which Bank reasonably
determines to be allocable to the existence of any obligations of the Bank
hereunder or to the making or maintaining any Advances hereunder. A certificate
of Bank as to the amount of such compensation, prepared in good faith and in
reasonable detail by the Bank and submitted by Bank to Borrower, shall be
conclusive and binding for all purposes absent manifest error in computation.

     This Note and any other indebtedness and liabilities of any kind of
Borrower to Bank, and any and all modifications, renewals or extensions thereof,
whether joint or several, contingent or absolute, direct or indirect, now
existing or later arising, and however evidenced (collectively the
"Indebtedness"), are secured by and Bank is granted a security interest in all
items at any time deposited in any account of Borrower with Bank and by all
proceeds of these items (cash or otherwise), all account balances of Borrower
from time to time with Bank, by all property of Borrower from time to time in
the possession of Bank, and by any other collateral, rights and properties
described in each and every mortgage, security agreement, pledge, assignment and
other security or collateral agreement which has been, or will at any time(s)
later be, executed by Borrower or others to or for the benefit of Bank
(collectively the "Collateral").

     If Borrower or any guarantor under a guaranty of all or part of the
Indebtedness ("guarantor") (a) fail(s) to pay this Note, or any part thereof, or
any of the Indebtedness when due, by maturity, acceleration or otherwise, or
fail(s) to pay any Indebtedness owing on a demand basis upon demand; or (b)
fail(s) to comply with any of the terms or provisions of any agreement between
Borrower or any guarantor and Bank; or (c) become(s) insolvent or the subject of
a voluntary or involuntary proceeding in bankruptcy, or a reorganization,
arrangement or creditor composition proceeding, (if a business entity) cease(s)

                               (Eurodollar Rate)


$9,000,000                                                     Detroit, Michigan
                                                                October 31, 1997



     On or before April 1, 1999 (herein called the "Maturity Date"), FOR VALUE
RECEIVED, the undersigned, Cade Industries, Inc., a Wisconsin corporation
(herein called "Borrower"), promises to pay to the order of COMERICA BANK, a
Michigan banking corporation (herein called "Bank"), in lawful currency of the
United States of America, the principal sum of NINE MILLION DOLLARS
($9,000,000), or so much of said sum as has been advanced and is then
outstanding under this Note, together with interest thereon as hereinafter set
forth.

     This Note is a note under which Advances, repayments and re-Advances may be
made from time to time, subject to the terms and conditions of this Note;
provided, however, in no event shall Bank be obligated to make any Advances or
re-Advances hereunder (notwithstanding anything expressed or implied herein or
elsewhere to the contrary).

     Each of the Advances made hereunder shall bear interest at the Eurodollar-
based Rate or the Prime-based Rate, as elected by Borrower or as otherwise
determined under this Note.

     Accrued and unpaid interest on the unpaid balance of each outstanding
Prime-based Advance shall be payable quarterly, in arrears, commencing on
January 1, 1998, and on the first Business Day of each succeeding quarter
thereafter, until maturity (whether as stated herein, by acceleration, or
otherwise).  Interest accruing at the Prime-based Rate shall be computed on the
basis of a year of 360 days, and shall be assessed for the actual number of days
elapsed, and in such computation, effect shall be given to any change in the
Applicable Interest Rate as a result of any change in the Prime-based Rate on
the date of each such change in the Prime-based Rate.

     Accrued and unpaid interest on each Eurodollar-based Advance shall be
payable on the last day of the Interest Period applicable thereto (unless sooner
accelerated in accordance with the terms of this Note).  Interest accruing at
the Eurodollar-based Rate shall be computed on the basis of a 360 day year and
shall be assessed for the actual number of days elapsed from the first day of
the Interest period applicable thereto but not including the last day thereof.
<PAGE>
 
     From and after the occurrence of any Default hereunder, and so long as any
such Default remains unremedied or unaccrued thereafter, the Indebtedness
outstanding under this Note shall bear interest a per annum rate of three
percent (3%) above the otherwise Applicable Interest Rate, which interest shall
be payable upon demand.

     The amount and date of each Advance, its Applicable Interest Rate, its
Interest Period, if any, and the amount and date of any repayment shall be noted
on Bank's records, which records shall be conclusive evidence thereof, absent
manifest error; provided, however, any failure by Bank to make any such
notation, or any error in any such notation, shall not relieve Borrower of its
obligations to repay Bank all amounts payable by Borrower to Bank under or
pursuant to this Note, when due in accordance with the terms hereof.

     Borrower may request an Advance hereunder, including the refunding of an
outstanding Advance as the same type of Advance or the conversion of an
outstanding Advance as the same type of Advance, upon the delivery to Bank of a
Request for Advance executed by an authorized officer of Borrower, subject to
the following:

     (a)  no Default, and no condition or event which, with the giving of notice
          or the running of time, or both, would constitute a Default, shall
          have occurred and be continuing or exist under this Note;

     (b)  each such Request for Advance shall set forth the information required
          on the Request for Advance form annexed hereto as Exhibit "A";

     (c)  each such Request for Advance shall be delivered to Bank by 11:00 a.m.
          (Detroit, Michigan time) one (1) Business Day prior to the proposed
          date of Advance in the case of Eurodollar-based Advances, and by 11:00
          a.m. (Detroit, Michigan time) on the proposed date of Advance in the
          case of Prime-based Advances;

     (d)  the principal amount of each Eurodollar-based Advance shall be at
          least Five Hundred Thousand Dollars ($500,000);

     (e)  the proposed date of any refunding of any outstanding Eurodollar-based
          Advance as another Eurodollar-based Advance or the conversion of any
          outstanding Eurodollar-based Advance to a Prime-based Advance shall
          only be on the last day of the Interest Period applicable to such
          outstanding Eurodollar-based Advance; and

                                       2
<PAGE>
 
     (f)  a Request for Advance, once delivered to Bank, shall not be revocable
          by Borrower; provided, however, as aforesaid, Bank shall not be
          obligated to make any Advance under this Note.

     If, as to any outstanding Eurodollar-based Advance, Bank shall not receive
a timely Request for Advance in accordance with the foregoing requesting the
refunding of such Advance as a Eurodollar-based Advance, the principal amount of
such Advance which is not then repaid shall be automatically converted to a
Prime-based Advance on the last day of the Interest Period applicable thereto,
subject in all respects to the terms and conditions of this Note. The foregoing
shall not in any way whatsoever limit or otherwise affect any of Bank's rights
or remedies under this Note upon the occurrence of any Default hereunder, or any
condition or event which, with the giving of notice or the running of time, or
both, would constitute a Default.

     Borrower may prepay all or part of the outstanding balance of any Prime-
based Advance under this Note at any time.  Borrower may prepay all or part of
any Eurodollar-based Advance on the last day of the Interest Period applicable
thereto, provided that the aggregate balance of Eurodollar-based Advances
outstanding after such prepayment shall be at least Five Hundred Thousand
Dollars ($500,000), and the unpaid portion of such Eurodollar-based Advance
which is then refunded or converted shall be subject to the limitations set
forth in this Note.  Any prepayment made in accordance with this paragraph shall
be without premium or penalty. Any other prepayment shall be otherwise
restricted by and subject to the terms of this Note.

     Subject to the definition of an "Interest Period" hereunder, in the event
that any payment under this Note becomes due and payable on any day which is not
a Business Day, the due date thereof shall be extended to the next succeeding
Business Day, and, to the extent applicable, interest shall continue to accrue
and be payable thereon during such extension at the rates set forth in this
Note.

     All payments to be made by Borrower to Bank under or pursuant to this Note
shall be in immediately available funds, without setoff or counterclaim, and in
the event that any payments submitted hereunder are in funds not available until
collected, said payments shall continue to bear interest until collected.
Borrower hereby authorizes Bank to charge any account of Borrower with Bank for
all sums due hereunder when due in accordance with the terms hereof.

     If Borrower makes any payment of principal with respect to any Eurodollar-
based Advance on any day other than the last day of the Interest Period
applicable thereto (whether voluntarily, by acceleration, or otherwise), or if
Borrower fails to borrow any 

                                       3
<PAGE>
 
Eurodollar-based Advance after notice has been given by Borrower to Bank in
accordance with the terms of this Note requesting such Advance, or if Borrower
fails to make any payment of principal or interest in respect of a Eurodollar-
based Advance when due, Borrower shall reimburse Bank, on demand, for any
resulting loss, cost or expense incurred by Bank as a result thereof, including,
without limitation, any such loss, or expense incurred in obtaining,
liquidating, employing or redeploying deposits from third parties, whether or
not Bank shall have funded or committed to fund such Advance. Such amount
payable by Borrower to Bank may include, without limitation, an amount equal to
the excess, if any, of (a) the amount of interest which would have accrued on
the amount so prepaid, or not so borrowed, refunded or converted, for the period
from the date of such prepayment or of such failure to borrow, refund, or
convert, through the last day of the relevant Interest Period, at the applicable
rate of interest for said Advance(s) provided under this Note, over (b) the
amount of interest (as reasonably determined by Bank) which would have accrued
to Bank on such amount by placing such amount on deposit for a comparable period
with leading banks in the interbank eurodollar market. Calculation of any
amounts payable to Bank under this paragraph shall be made as though Bank shall
have actually funded or committed to fund the relevant Eurodollar-based Advance
through the purchase of an underlying deposit in an amount equal to the amount
of such Advance and having a maturity comparable to the relevant Interest
Period; provided, however, that Bank may fund any Eurodollar-based Advance in
any manner it deems fit and the foregoing assumptions shall be utilized only for
the purpose of the calculation of amounts payable under this paragraph. Upon the
written request of Borrower, Bank shall deliver to Borrower a certificate
setting forth the basis for determining such losses, costs and expenses, which
certificate shall be conclusively presumed correct, absent manifest error.

     For any Eurodollar-based Advance, if Bank shall designate a Eurodollar
Lending Office which maintains books separate from those of the rest of Bank,
Bank shall have the option of maintaining and carrying such Advance on the books
of such Eurodollar Lending Office.

     If, with respect to any Interest Period, Bank determines that, (a) by
reason of circumstances affecting the foreign exchange and interbank markets
generally, deposits in Eurodollars in the applicable amounts or for the relative
maturities are not being offered to Bank for such Interest Period, or (b) if the
rate of interest referred to in the definition of "Eurodollar-based Rate" upon
the basis of which the rate of interest for a Eurodollar-based Advance is to be
determined does not accurately or fairly cover or reflect the cost to Bank of
making or maintaining a Eurodollar-based Advance hereunder, then Bank shall
forthwith give notice thereof to the Borrower.  Thereafter, until Bank notifies
Borrower that such conditions or circumstances no longer exist, the right of

                                       4
<PAGE>
 
Borrower to request a Eurodollar-based Advance and to convert an Advance to or
refund an Advance as a Eurodollar-based Advance shall be suspended.

     If, after the date hereof, the introduction of, or any change in, any
applicable law, rule or regulation or in the interpretation or administration
thereof by any governmental authority charged with the interpretation or
administration thereof, or compliance by Bank (or its Eurodollar Lending Office)
with any request or directive (whether or not having the force of law) of any
such authority, shall make it unlawful or impossible for the Bank (or its
Eurodollar Lending Office) to make or maintain any Advance with interest at the
Eurodollar-based Rate, Bank shall forthwith give notice thereof to Borrower.
Thereafter, (a) until Bank notifies Borrower that such conditions or
circumstances no longer exist, the right of Borrower to request a Eurodollar-
based Advance and to convert an Advance to or refund an Advance as a Eurodollar-
based Advance shall be suspended, and thereafter, Borrower may select only the
Prime-based Rate as the Applicable Interest Rate hereunder, and (b) if Bank may
not lawfully continue to maintain an outstanding Advance to the end of the then
current Interest Period applicable thereto, the Prime-based Rate shall be the
Applicable Interest Rate for the remainder of such Interest Period with respect
to such outstanding Advance.

     If the adoption after the date hereof, or any change after the date hereof
in, any applicable law, rule or regulation of any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by Bank (or its Eurodollar Lending Office)
with any request or directive (whether or not having the force of law) made by
any such authority, central bank or comparable agency after the date hereof:

     (a)  shall subject Bank (or its Eurodollar Lending Office) to any tax, duty
          or other charge with respect to this Note or any Advance hereunder or
          shall change the basis of taxation of payments to Bank (or its
          Eurodollar Lending Office) of the principal of or interest on any
          Advance or any other amounts due under this Note in respect thereof
          (except for changes in the rate of tax on the overall net income of
          Bank or its Eurodollar Lending Office imposed by the jurisdiction in
          which Bank's principal executive office or Eurodollar Lending Office
          is located); or

     (b)  shall impose, modify or deem applicable any reserve (including,
          without limitation, any imposed by the Board of Governors of the
          Federal Reserve System), special deposit or similar requirements
          against assets of, deposits with or for the account of, or credit
          extended by Bank (or its Eurodollar Lending Office) or shall impose on
          Bank (or its Eurodollar Lending Office) or the

                                       5
<PAGE>
 
          foreign exchange and interbank markets any other condition
          affecting any Advance under this Note;

and the result of any of the foregoing is to increase the cost to Bank of
maintaining any part of the indebtedness hereunder or to reduce the amount of
any sum received or receivable by Bank under this Note by an amount deemed by
the Bank to be material, then Borrower shall pay to Bank, within fifteen (15)
days of Borrower's receipt of written notice from Bank demanding such
compensation, such additional amount or amounts as will compensate Bank for such
increased cost or reduction.  A certificate of Bank, prepared in good faith and
in reasonable detail by Bank and submitted by Bank to Borrower setting forth the
basis for determining such additional amount or amounts necessary to compensate
Bank shall be conclusive and binding for all purposes, absent manifest error in
computation.

     In the event that any applicable law, treaty, rule or regulation (whether
domestic or foreign) now or hereafter in effect and whether or not presently
applicable to Bank, or any interpretation or administration thereof by any
governmental authority charged with the interpretation or administration
thereof, or compliance by Bank with any guideline, request or directive of any
such authority (whether or not having the force of law), including any risk-
based capital guidelines, affects or would affect the amount of capital required
or expected to be maintained by Bank (or any corporation controlling Bank), and
Bank determines that the amount of such capital is increased by or based upon
the existence of any obligations of Bank hereunder or the making or maintaining
any Advances hereunder, and such increase has the effect of reducing the rate of
return on Bank's (or such controlling corporation's) capital as a consequence of
such obligations or the making or maintaining of such Advances hereunder to a
level below that which Bank (or such controlling corporation) could have
achieved but for such circumstances (taking into consideration its policies with
respect to capital adequacy), then Borrower shall pay to Bank, within fifteen
(15) days of Borrower's receipt of written notice from Bank demanding such
compensation, additional amounts as are sufficient to compensate Bank (or such
controlling corporation) for any increase in the amount of capital and reduced
rate of return which Bank reasonably determines to be allocable to the existence
of any obligations of the Bank hereunder or to be making or maintaining any
Advances hereunder.  A certificate of Bank as to the amount of such
compensation, prepared in good faith and in reasonable detail by the Bank and
submitted by Bank to Borrower, shall be conclusive and binding for all purposes
absent manifest error in computation.

     This Note and any other indebtedness and liabilities of any kind of
Borrower to Bank, and any and all modifications, renewals or extensions thereof,
whether joint or several, contingent or absolute, direct or indirect, now
existing or later arising, and however evidenced (collectively the
"Indebtedness"), are secured by 

                                       6
<PAGE>
 
and Bank is granted a security interest in all items at any time deposited in
any account of Borrower with Bank and by all proceeds of these items (cash or
otherwise,) all account balances of Borrower from time to time with Bank, by all
property of Borrower from time to time in the possession of Bank, and by any
other collateral, rights and properties described in each and every mortgage,
security agreement, pledge, assignment and other security or collateral
agreement which has been or will at any time(s) later be, executed by Borrower
or others to or for the benefit of Bank (collectively the "Collateral").

     If Borrower or any guarantor under a guaranty of all or part of the
Indebtedness ("guarantor") (a) fail(s) to pay this Note, or any part thereof, or
any of the Indebtedness when due, by maturity, acceleration or otherwise, or
fail(s) to pay any Indebtedness owing on a demand basis upon demand; or (b)
fail(s) to comply with any of the terms or provisions of any agreement between
Borrower or any guarantor and Bank; or (c) become(s) insolvent or the subject of
a voluntary or involuntary proceeding in bankruptcy, or a reorganization,
arrangement or creditor composition proceeding, (if a business entity) cease(s)
doing business as a going concern, (if a natural person) die(s) or become(s)
incompetent, (if a partnership) dissolve(s) or any general partner of it dies,
becomes incompetent or becomes the subject of a bankruptcy proceeding, or (if a
corporation) is the subject of a dissolution, merger or consolidation; or (d) if
any warranty or representation made by Borrower or any guarantor in connection
with this Note or any of the Indebtedness shall be discovered to be untrue or
incomplete in any material respect; (e) or if there is any termination, notice
of termination, or breach of any guaranty, pledge, collateral assignment or
subordination agreement relating to all or any part of the Indebtedness; or (f)
if there is any failure by Borrower or any guarantor to pay, when due, any of
its indebtedness (other than to the Bank) or in the observance or performance of
any term, covenant or condition in any document evidencing, securing or relating
to such indebtedness; or (g) if there is filed or issued a levy or writ of
attachment or garnishment or other like judicial process upon Borrower or any
guarantor or any of the Collateral, including, without limit, any accounts of
Borrower or any guarantor with Bank, then Bank, upon the occurrence and at any
time during the continuance or existence of any of these conditions or events
(each a "Default"), may at its option and without prior notice to Borrower,
declare any or all of the Indebtedness to be immediately due and payable
(notwithstanding any provisions contained in the evidence of it to the
contrary), sell or liquidate all or any portion of the Collateral, set off
against the Indebtedness any amounts owing by Bank to Borrower, and exercise any
one or more of the rights and remedies granted to Bank by an agreement with
Borrower given to it under applicable law, or otherwise.
 
     Borrower waives presentment, demand, protest, notice of dishonor, notice of
demand or intent to demand, notice of 

                                       7

acceleration or intent to accelerate, and all other notices, and agrees that no
extension or indulgence to Borrower, or release, substitution or nonenforcement
of any security, or release or substitution of any guarantor or any other party,
whether with or without notice, shall affect the obligations of Borrower.
Borrower waives all defenses or right to discharge available under Section 3-605
of the Uniform Commercial Code and waives all other suretyship defenses or right
to discharge. Borrower agrees that Bank has the right to sell, assign, or grant
participations, or any interest, in any or all of the Indebtedness, and that, in
connection with such right, but without limiting its ability to make other
disclosures to the full extent allowable, Bank may disclose all documents and
information which the Bank now or later has relating to Borrower and the
Indebtedness.

     Borrower agrees to reimburse Bank, or any other holder or owner of this
Note, for any and all costs and expenses (including, without limit, court costs,
legal expenses and reasonable attorneys' fees, whether inside or outside counsel
is used, whether or not suit is instituted, and, if suit is instituted, whether
at the trial court level, appellate level, in a bankruptcy, probate or
administrative proceeding or otherwise) incurred in collecting or attempting to
collect this Note or the Indebtedness or incurred in any other matter or
proceeding relating to this Note or the Indebtedness.

     Borrower acknowledges and agrees that there are no contrary agreements,
oral or written, establishing a term of this Note and agrees that the terms and
conditions of this Note may not be amended, waived or modified except in a
writing signed by a duly authorized officer of Bank expressly stating that the
writing constitutes an amendment, waiver or modification of the terms of this
Note.  If any provision of this Note is unenforceable in whole or part for any
reason, the remaining provisions shall continue to be effective.  THIS NOTE
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
MICHIGAN.

whatsoever, the Bank shall ever receive as interest an amount which would be
deemed unlawful under such applicable law, such interest shall be automatically
