         To induce the Bank to enter into this Agreement and to make the Loans,
the Borrower represents and warrants to the Bank that the following statements
are true, correct and accurate both before and after giving effect to the
transactions contemplated by the Loan Documents:

         2.1 The Borrower is a corporation duly organized, validly existing, and
in good standing under the laws of the State of Michigan. The Borrower is duly
qualified and authorized to do business, and is in good standing as a foreign
corporation, in all jurisdictions in which the failure to be so qualified or
authorized to do business would have a Material Adverse Effect.

         2.2 The Borrower has all requisite corporate power and authority and
all necessary licenses and permits to own and operate its properties and to
carry on its business as now conducted and as it contemplates that business to
be conducted in the future. The Borrower is in compliance with all laws, rules,
and regulations, the non-compliance with which would have a Material Adverse
Effect.

         2.3 All financial statements of the Borrower that have been delivered
to the Bank, including the internally prepared financial statements for the
period ending May 31, 1999, have been prepared in accordance with GAAP and
present fairly the financial position of the Borrower as of the dates indicated,
and the results of its operations for the periods indicated. No changes having a
Material Adverse Effect have occurred since the date of the most recent of such
financial statements. Except as expressly set forth in such financial
statements, the Borrower has no material contingent liability or liability for
taxes, long-term lease or unusual forward or long-term commitment.


                                       27
<PAGE>   6

         2.4 Neither this Agreement nor the financial statements referred to in
Section 2.3 above, nor any other written statement furnished by or on behalf of
the Borrower to the Bank in connection with the negotiation of the Loans
provided for herein, contains any untrue statement of a material fact or omits a
material fact necessary to make the statements contained therein or herein not
misleading. To Borrower's Knowledge, there is no fact that the Borrower has not
disclosed to the Bank in writing that has, or in the future is likely to have, a
Material Adverse Effect.

         2.5 There are no proceedings pending, or to Borrower's Knowledge
threatened, before any court, governmental authority, or arbitration board or
tribunal, against or affecting the Borrower, the outcome of which may reasonably
be expected to have a Material Adverse Effect. The Borrower is not in default
with respect to any order, judgment, or decree of any court, governmental
authority, or arbitration board or tribunal.

         2.6 All of the outstanding capital stock of the Borrower is validly
issued, fully paid and nonassessable.

         2.7 The Borrower has good and marketable title to all of the assets
that it purports to own, including the assets described in the financial
statements referred to in Section 2.3 hereof, free and clear from all liens,
encumbrances, security interests, claims, charges, and restrictions whatever,
except Permitted Liens. The Borrower owns no real property. All real property
leased by the Borrower is suitable for its current intended purposes and is
served by such utilities and has such access to public roadways and other
transportation structures and systems as are necessary for the proper and
efficient use, operation and maintenance thereof. The Borrower enjoys peaceful
and undisturbed possession under all real property leases to which it is a
party, and all such leases are valid and subsisting and in full force and effect
and no default (nor any event which, with notice or lapse of time or both, would
constitute such a default) has occurred or is continuing under any of such
leases on the part of the Borrower or, to Borrower's Knowledge, on the part of
the landlord. There have been no renewals or extensions of or supplements,
modifications or amendments to any of such leases except as previously disclosed
in writing to the Bank.

         2.8 The Borrower owns and controls all of the patents, trademarks,
service marks, trade names, copyrights, licenses, and rights necessary for the
present and planned future conduct of its business, without any conflict with
the right of any other person, firm, or corporation.

         2.9 The Borrower has full corporate power and authority to execute,
deliver, and perform the Loan Documents; the execution, delivery, and
performance of the Loan Documents required to be given hereunder by the Borrower
have been duly authorized by appropriate corporate action of the Borrower and
will not violate the provisions of the articles of incorporation or bylaws of
the Borrower or of any law, rule, judgment, order, agreement, or instrument to
which the Borrower is a party or by which it is bound, or to which any of its
assets are subject, nor do the same require any approval or consent of any
public authority or other third party; and the Loan Documents have been duly
executed and delivered by, and are the valid and binding obligations of, the
parties thereto, enforceable in accordance with their terms.

         2.10 All tax returns required to be filed by the Borrower in any
jurisdiction have been filed, and all taxes, assessments, fees, and other
governmental charges upon the Borrower or upon its assets, income, or franchises
have been paid before the time that those taxes became delinquent. The Borrower
knows of no proposed additional tax assessment against it.

         2.11 The Borrower has no investments in the securities of any other
corporation or business entity. The Borrower does not intend to carry or
purchase any "margin security" within the meaning of Regulation U of the Board
of Governors of the Federal Reserve System, 12 C.F.R. Chapter II.

         2.12 Attached hereto as Schedule 2.12 is a list of all Plans. No Plan
has been terminated since the effective date of ERISA. No Plan is a
"multi-employer plan" within the meaning of Section 3(37)(A) of ERISA.




                                       28
<PAGE>   7

No "accumulated deficiency" (within the meaning of Section 412 of ERISA) or
"reportable event" (as defined in Title IV of ERISA) has occurred with respect
to any Plan. Neither the Borrower nor any Affiliate has incurred any material
liability to the Pension Benefit Guaranty Corporation ("PBGC") or otherwise
under ERISA. The PBGC has not started or threatened to institute a proceeding
against the Borrower or any Affiliate under ERISA.

         2.13 All of the Borrower's assets, operations and activities are in
compliance with all Environmental Laws; and none of the Borrower's property is
(a) in violation of Environmental Laws, (b) Contaminated by, or the site of, the
disposal or release of any Hazardous Substance; (c) the source of any
Contamination of any adjacent property or of any groundwater or surface water;
or (d) the source of any air emissions in excess of any legal limit now or
hereafter in effect. There is no civil, criminal or administrative action, suit,
demand, claim, hearing, notice of violation or deficiency, investigation,
proceeding, notice or demand letter pending or, to Borrower's Knowledge,
threatened against the Borrower under any Environmental Law which could
reasonably be expected to result in a fine, penalty or other cost or expense.

         2.14 The execution, delivery and performance by the Borrower of each
Loan Document, the issuance, delivery and performance of the Notes, and the
consummation of the transactions contemplated hereby or related hereto do not
and will not (a) conflict with, result in a breach of or constitute (with due
notice or lapse of time or both) a default under any contractual obligation of
the Borrower, (b) result in or require the creation or imposition of any lien
(other than liens in favor of the Bank) upon any of its properties or assets, or
(c) require any approval of stockholders that has not been obtained or any
approval or consent of any person under any actual or purported contractual
obligation of the Borrower.

         2.15 The Borrower is not in default in the performance, observance or
fulfillment of any of the obligations, covenants or conditions contained in any
actual or purported contractual obligation of the Borrower, and no condition
exists that, with the giving of notice or the lapse of time or both, would
constitute such a default, which default could have a Material Adverse Effect.

in this Agreement as a "Note", and are collectively referred to in this
Agreement as the "Notes". Each of the Loans is subject to the terms and

SECTION 4 - INTEREST RATES AND ADVANCE PROCEDURES

         4.1 The Borrower may elect, subject to the terms of this Agreement, to
have the Revolving L/C Loan and the Existing Equipment Term Loan bear interest
as follows:

                  (a) The unpaid principal balance of the Revolving L/C Loan may
bear interest at a rate that is equal to: (i) the Prime Rate minus 25 basis
points (such interest rate is referred to below as the "Prime-Based Index"); or
(ii) 225 basis points plus the LIBOR (London Inter-bank Offered Rate) for the
applicable LIBOR Period described in paragraph (c) below (such interest rate is
referred to below as the "LIBOR-Based Index"). In the absence of an effective
election by the Borrower to have the interest rate on all or part of the
Revolving L/C Loan determined on the basis of the LIBOR-Based Index, interest on
such indebtedness shall be determined on the basis of the Prime-Based Index.

                  (b) The unpaid principal balance of the Existing Equipment
Term Loan may bear interest at a rate that is equal to: (i) the Prime-Based
Index; or (ii) the LIBOR-Based Index; or (iii) 250 basis points plus the Five
(5)-Year Treasury Rate on the Interest Rate Determination Date (such interest
rate is referred to below as the "5-Year Treasury-Based Index"). In the absence
of an effective election by the Borrower to have the interest rate on all or
part of the Existing Equipment Term Loan determined on the basis of the
LIBOR-Based Index or the 5-Year Treasury-Based Index, interest on such
indebtedness shall be determined on the basis of the Prime-Based Index.

                  (c) The applicable LIBOR Period for any indebtedness under
this Agreement for which interest is determined on the basis of the LIBOR-Based
Index shall be one of the following, as specified in writing by the Borrower
when giving notice to the Bank pursuant paragraph (g) below: (i) loans having
30-day maturities, (ii) loans having 60-day maturities, and (iii) loans having
90-day maturities; provided, however, that the Borrower may not select a LIBOR
Period that extends beyond the maturity date for the pertinent Loan.



                                       32
<PAGE>   11

                  (d) For any Loan as to which the Borrower elects the
LIBOR-Based Index, the original principal amount with respect to which interest
may be determined on the basis of the LIBOR-Based Index shall be not less than
$500,000, or whole multiples of that amount, as specified in writing by the
Borrower when giving notice to the Bank pursuant to paragraph (g) below.

                  (e) Subject to compliance with paragraph (d) above, the
Borrower may elect to divide the unpaid principal balance of a Loan into two or
more segments (each such segment is referred to as a "Loan Segment"), and to
have interest as to one Loan Segment determined on the basis of the Prime-Based
Index and interest as to the other Loan Segment(s) determined on the basis of
the LIBOR-Based Index; different LIBOR Periods may be used for each Loan Segment
as to which the LIBOR-Based Index has been designated.

                  (f) If the Borrower elects to have interest for the Existing
Equipment Term Loan determined on the basis of the 5-Year Treasury-Based Index,
such election must be made as to the entire principal balance of such Loan.

                  (g) To make an election to have the interest on the Borrower's
indebtedness to the Bank determined on the basis of the LIBOR-Based Index, the
Borrower shall give the Bank written notice on the Bank's standard request form
from time to time (the Borrower acknowledges receipt of a copy of the Bank's
current form for such purpose, and the Bank shall furnish the Borrower with any
revisions thereof not less than ten (10) Business Days prior to requiring their
use. Any such election shall become effective upon the later of: (i) the third
(3rd) Business Day after the Bank's receipt of such written notice or (ii) the
funding date specified in such written notice.

                  (h) The Borrower may prepay, in whole or in part, a Loan or
Loan Segment with respect to which interest in determined on the basis of the
LIBOR-Based Index; provided, however that simultaneously with making any such
prepayment, the Borrower shall pay, in addition to the accrued interest on the
amount prepaid through the date of prepayment, an amount equal to the interest
that would have accrued through the applicable LIBOR Period on the principal
amount so prepaid.

                  (i) During the continuation of an Event of Default under the
Loan Agreement, the Borrower shall have no right to change the rate at which
interest is payable on the outstanding indebtedness under any of the Loans.

         4.2 The Borrower shall give the Bank notice of its request for each
Loan advance (each a "Notice of Borrowing") not later than 12:00 noon, Grand
Rapids, Michigan time, on the date such advance is requested to be made. The
Notice of Borrowing shall state whether the advance is requested under the
Revolving L/C Loan or the 1999 Equipment L/C Loan. Subject to the terms and
conditions of this Agreement, the proceeds of each such requested advance shall
be made available to the Borrower by depositing the proceeds thereof, in
immediately available funds, in an account maintained and designated by Borrower
at an office of the Bank.

         4.3 Except in the case of the initial Loan advances, for which the
applicable basis for determining the rate of interest must have been provided in
writing to the Bank not less than three Business Days prior to such advances,
and subject to the terms and conditions of this Agreement, the applicable basis
for determining the rate of interest with respect to advances under the Existing
Equipment Term Loan shall be selected by the Borrower at the time a Notice of
Borrowing is given pursuant to Section 4.2.

         4.4 Unless otherwise requested in writing by the Borrower, the interest
rate on all Loans shall be determined with reference to the Prime Rate.

         4.5 Notwithstanding anything to the contrary contained in the Loan
Documents, following acceleration or maturity of any Indebtedness evidenced by a
Note, the outstanding principal balance of such Loan will bear interest at the
rate of 300 basis points above the rate that would otherwise be in effect.



                                       33
<PAGE>   12

         4.6 The Borrower may prepay any part of the principal balance of a
Prime Rate Advance at any time, without prior notice to the Bank and without
prepayment penalty or premium. The Borrower may prepay all or any part of the
principal balance of a T-Bill Rate Advance on one (1) Business Day's notice
provided that, in addition to all principal, interest and costs owing at the
time of prepayment, there shall be due and owing from the Borrower a prepayment
premium in an amount equal to:

                  (a) Five percent (5%) of the principal amount paid, if the
T-Bill Rate Advance is paid more than 48 months prior to its scheduled maturity;

                  (b) Four percent (4%) of the principal amount paid, if the
T-Bill Rate Advance is paid more than 36 months but less than 49 months prior to
its scheduled maturity;

                  (c) Three percent (3%) of the principal amount paid, if the
T-Bill Rate Advance is paid more than 24 months but less than 37 months prior to
its scheduled maturity;

                  (d) Two percent (2%) of the principal amount paid, if the
T-Bill Rate Advance is paid more than 12 months but less than 25 months prior to
its scheduled maturity; and

                  (e) One percent (1%) of the principal amount paid, if the
T-Bill Rate Advance is paid 12 months, or less, prior to its scheduled maturity.

                  Notwithstanding the foregoing, the Borrower shall not be
obligated to pay a prepayment premium if the Indebtedness evidenced by a Note is
prepaid after acceleration by the Bank.

         4.7 Any amounts applied to the outstanding principal of a T-Bill Rate
Advance prior to its maturity or acceleration shall be deemed to be a prepayment
of principal to which the prepayment notice and premium provisions of this
Agreement shall apply. Prior to maturity or acceleration of any Indebtedness
under this Agreement, amounts repaid by the Borrower shall be applied to the
outstanding indebtedness under this Agreement as designated by the Borrower. If,
prior to maturity or acceleration of any Indebtedness under this Agreement, the
Borrower fails to designate how Loan repayments should be applied, the Loan
repayments automatically shall be applied first to interest, then to Prime Rate
Advances principal, and then to T-Bill Rate Advances principal. Any Loan
repayments received by the Bank after maturity or acceleration of any
Indebtedness under this Agreement may be applied by the Bank in any manner
determined by the Bank, in its sole discretion.

         4.8 Interest on advances shall be computed on the basis of a 360-day
year and the actual number of days elapsed in the period during which it
accrues. In computing interest on any advance, the date of the making of the
advance shall be included and the date payment is received shall be excluded;
provided that if an advance is repaid on the same day on which it is made, one
day's interest shall be paid on that advance.

         4.9 The Borrower acknowledges that the Bank shall at no time ever be
obligated pursuant to this Agreement to advance to the Borrower more than (a) a
total of $3,250,000 under the Existing Equipment Term Loan, (b) a total of
$4,000,000 under the Equipment Term Loan, (c) $3,271,000 under the 1999
Equipment L/C Loan, and (c) $1,000,000 under the $1,000,000.00 Equipment Term
Loan, and that the Existing Equipment Term Loan, the Equipment Term Loan, the
1999 Equipment L/C Loan and the $1,000,000.00 Term Loan are not revolving loans.
Once repaid, amounts borrowed under the Existing Equipment Term Loan, the
Equipment Term Loan, the 1999 Equipment L/C Loan and the $1,000,000.00 Term Loan
may not be reborrowed.

         4.10 Subject to the terms and conditions of this Agreement, amounts
borrowed under the Revolving L/C Loan may be repaid and reborrowed.

to the Bank under this Agreement and all other indebtedness and obligations now
and hereafter owing by the Borrower to the Bank, the Borrower shall execute and
deliver to the Bank:

                  (a) security agreements, in form and substance satisfactory to

                  (c) all financing statements, assignments, document of title,

continuing security interest in (a) all securities and other property of the
Borrower in the custody, possession or control of the Bank (other than property
held by the Bank solely in a fiduciary capacity) and (b) all balances of deposit
accounts of the Borrower with the Bank. The Bank shall have the right at any
time after an Event of Default, or any event which with the giving of notice or
lapse of time, or both, would constitute an Event of Default, to apply its own
debt or liability to the Borrower in whole or partial payment of such Loans or
other present or future liabilities, without any requirement of mutual maturity.

in this Agreement are satisfied, showing the calculations for making such
determinations, and otherwise in a form acceptable to Bank.

         6.2 Promptly inform the Bank of any occurrence that is an Event of
Default as defined in Section 9 hereof or that, with the giving of notice or the

indebtedness and obligations owing by it, and pay all claims (including, without
limitation, claims for labor, services, materials and supplies) for sums which

indebtedness, obligation or claim.

capital stock or declare or pay dividends or make any other distribution of its
assets, by reduction of capital or otherwise; provided, however, that the
Borrower may declare and pay stock (i.e., non-cash) dividends without the Bank's
consent if such actions will not cause the Borrower to be in breach of any other
covenant, term or provision of the Loan Documents.

         7.7 Subordinate any indebtedness owing to the Borrower by any person,
firm, or corporation to indebtedness of that person, firm, or corporation owing

by GAAP, as hereafter modified.

         7.13 Change its name without prior written approval from the Bank;
except that the Borrower may change its name if the Borrower has given 60 days'
prior written notice of the name change and has taken such action as the Bank
deems necessary to continue the perfection of the security interests and liens
granted to the Bank under the Loan Documents.

SECTION 8 - APPLICATION OF PROCEEDS

         The proceeds of each Loan shall be used by the Borrower solely for the
purpose set forth for such Loan in Section 3, and for no other purpose.

SECTION 9 - EVENTS OF DEFAULT AND REMEDIES

         9.1 The following events shall constitute an "Event of Default" under
this Agreement, the occurrence of which shall entitle the Bank to pursue any and
all rights and remedies available to it under this Agreement, the Notes, the
other Loan Documents, and under applicable law. The Bank's rights and remedies
are cumulative and may be exercised concurrently or successively from time to
time. Any action by the Bank against any property or party shall not serve to
release or discharge any other security, property or party in connection with
this transaction. The Events of Default are as follows:

                  (a) Failure to pay the principal or interest on any loan
provided for under this Agreement when and as the same shall be due and payable,
whether by acceleration or otherwise, provided in each case that such default
has not been cured prior to the expiration of 10 days following the date of
personal delivery or mailing of written notice of such default to the Borrower.

                  (b) Failure to pay the principal or interest on any other
indebtedness now or hereafter owed by the Borrower to the Bank as the same shall
be due and payable, whether by acceleration or otherwise, provided in each case
that such default has not been cured prior to the expiration of 10 days
following the date of personal delivery or mailing of written notice of such
default to the Borrower.

                  (c) Failure to observe, perform and comply with any of the
Borrower's obligations under any Loan Document or failure to observe, perform
and comply with any of the Borrower's other obligations under any other document
that evidences, secures or otherwise relates to indebtedness of the Borrower to
the Bank, whether arising under this Agreement or otherwise, and failure to
observe, perform and comply with any and all other agreements between the
Borrower and the Bank to be observed, performed or complied with by the
Borrower; provided that such default has not been cured prior to the expiration
of 20 days following the date of personal delivery or mailing of written notice
of such default.

                  (d) Failure to pay any Indebtedness or trade debt of the
Borrower to any third party (i) when due upon agreed upon terms, unless a grace
period applies or the Borrower satisfies the conditions described in 9.1(d)(iii)
below, (ii) upon the expiration of an applicable grace period, unless the
Borrower satisfies the conditions described in 9.1(d)(iii), or (iii) provided
that the payment of such Indebtedness or trade debt is being contested in good
faith by appropriate proceedings, and the Borrower shall have set aside on its
books adequate reserves with respect to such Indebtedness or debt, at the time
that a final non-appealable decision is rendered in such proceedings.

                  (e) The discovery by the Bank of any material inaccuracy in
any statement, assurance, representation, covenant, warranty, term or condition
by the Borrower contained in this Agreement or in any document delivered or to
be delivered by or on behalf of the Borrower pursuant to this Agreement, or in
any other Loan Document, or in any other agreement between the Borrower and the
Bank.

                  (f) The filing of a petition by or against the Borrower or any
other obligor of any Loan seeking relief under the Federal Bankruptcy Code, 11
U.S.C. ss. 101, et seq., and any amendments thereto (the "Code"), or any similar
law or regulation, whether federal, state or local, not dismissed within 30
days.

                  (g) The commencement of a proceeding by or against the
Borrower or other obligor of a Loan under any statute or other law providing for
an assignment for the benefit of creditors, the appointment of a receiver, or
any other similar law or regulation, whether federal, state or local, not
dismissed within 30 days.

                  (h) The garnishment, attachment, levy or other similar action
taken by or on behalf of any creditor of the Borrower or any of its properties
which could have a Material Adverse Effect.

                  (i) The determination by the Bank or any one of its agents or
representatives that there exists any Hazardous Substances in violation of any
Environmental Laws on, in or under any of the collateral in which the Bank holds
an interest as security for any loan made pursuant to this Agreement.

         9.2 Upon the occurrence of any Event of Default set forth in
subsections 9.1(a) through 9.1(i) above, at the option of the Bank, the Bank's
obligation to make additional loan advances under this Agreement shall terminate
and the Bank shall have the right to declare all or any part of the unpaid
principal balance of, and accrued interest on, outstanding loans hereunder to be
immediately due and payable, without presentment, demand, or notice of any kind,
all of which are hereby expressly waived by the Borrower.

         9.3 Upon the occurrence of any Event of Default set forth in
subsections 9.1(a) through 9.1(i) above, the Bank shall have the right to
exercise any and all remedies that it may have for default under any Loan
Document or at law or in equity, and such remedies may be exercised concurrently
or separately until each and every one of the Borrower's obligations under the
Loan Documents has been fully satisfied. In connection with the enforcement of
any such remedies of the Bank, the Bank and its employees, attorneys, agents,
and other persons and entities designated by the Bank, shall have the right,
without notice, to enter the Borrower's plant and other places of business for
such purposes as may be reasonably required to permit the Bank to preserve,
protect, take possession of and/or sell or otherwise dispose of any Collateral,
and to store the Collateral at the Borrower's plant and other places of
business, without charge, for such periods as may be determined by the Bank.

SECTION 10 - CONDITIONS PRECEDENT TO ADVANCES UNDER THE LOANS.

         In addition to the other conditions precedent to advances described in
this Agreement, each Loan advance requested under this Agreement shall be
subject to prior satisfaction of the following conditions:

         10.1 The representations and warranties contained herein and in the
other Loan Documents shall be true, correct and accurate in all material
respects on and as of the Funding Date of such requested advance.

         10.2 No event shall have occurred and be continuing or would result
from the consummation of such borrowing or the application of the proceeds
thereof that would constitute a default, or any circumstance with which the
passing of time or the giving of notice could constitute a default, under this
Agreement or any Loan Document.

         10.3 The Borrower shall have performed in all material respects all
agreements and satisfied all conditions that this Agreement and each other Loan
Document provides shall be performed by it on or before such Funding Date.



                                       40
<PAGE>   19


         10.4 No order, judgment or decree of any court, arbitrator or
governmental authority shall purport to enjoin or restrain the Bank from making
such advance.

         10.5 There shall not be pending or, to Borrower's Knowledge threatened,
any action, suit, proceeding, governmental investigation or arbitration against
or affecting the Borrower or any property of the Borrower, and there shall have
occurred no development in any such action, suit, proceeding, governmental
investigation or arbitration previously disclosed to the Bank pursuant to this
Agreement, that, in the opinion of the Bank, would in any such case, reasonably
be expected to have a Material Adverse Effect upon the Borrower. No injunction
or other restraining order shall have been issued and no hearing to cause an
injunction or other restraining order shall be pending or noticed with respect
to any action, suit or proceeding seeking to enjoin or otherwise prevent the
consummation of, or to recover any damages or obtain relief as a result of, this
Agreement or the making of Loans hereunder.

         10.6 Since the date of the most recent financial statements submitted
to the Bank by or on behalf of the Borrower, nothing shall have occurred or
become known which the Bank shall have determined has a Material Adverse Effect
upon the Borrower.

         10.7 The Bank shall have received a Notice of Borrowing at the time and
in form required by Section 4.2 above. The furnishing by the Borrower of a
Notice of Borrowing shall be deemed to constitute a representation and warranty
of the Borrower to the effect that all the conditions set forth in this
Agreement for the requested advance are satisfied as of the date of delivery and
will be satisfied on the applicable Funding Date.

SECTION 11 - LIMITATION ON ADVANCES OF 1999 EQUIPMENT L/C LOAN.

         Notwithstanding anything to the contrary contained herein or in any of
the other Loan Documents, the 1999 Equipment L/C Loan is subject to the
following additional terms and conditions:

         11.1 The principal amount of each 1999 Equipment L/C Loan advance shall
not exceed an amount equal to one hundred percent (100%) of the Borrower's
actual cost for the equipment that will be purchased with the proceeds of such
advance (excluding tax, insurance, delivery and set-up charges, the cost of
maintenance contracts, and any other costs not paid or payable by the Borrower
to the equipment manufacturer as a direct cost of acquiring the equipment).

         11.2 The proceeds of each 1999 Equipment L/C Loan advance shall be
advanced by the Bank to the Borrower only after (i) receipt by the Bank of such
security agreements and financing statements (or supplements or amendments
thereto) covering the equipment, duly executed by the Borrower, (ii) receipt by
the Bank of such other documents as the Bank may reasonably require to create
and perfect its security interest therein, together with such evidence as the
Bank may reasonably require in order to establish the cost of such equipment to
the Borrower and that the equipment is completed and ready for shipment to the
Borrower, and (iii) the Borrower's compliance with the conditions described in
Section 10 above.

SECTION 12 - ACCEPTANCE OF PROCEEDS.

         The acceptance of the proceeds of each Loan shall constitute the
representation and warranty by the Borrower to the Bank that all of the
applicable conditions specified herein have been satisfied as of that time,
except for such conditions that have been expressly waived in writing hereunder
by the Bank.



                                       41
<PAGE>   20

SECTION 13 - MISCELLANEOUS

         13.1 The Borrower shall pay all out-of-pocket expenses incurred by the
Bank in connection with making and collecting the Loans and enforcing the Loan
Documents, including, but not limited to, reasonable attorneys' fees relating to
(a) the enforcement, or attempted enforcement, of any provision of any of the
Loan Documents, (b) the collection of any of the Loans, and (c) the foreclosure
of any security interests or other liens given with respect thereto.
Notwithstanding the foregoing, the Borrower shall not be obligated to pay more
than $4,500 in attorneys' fees incurred by the Bank in connection with making
the Loans (as contrasted with collecting the Loans, foreclosing the liens and
security interests securing the Loans, and otherwise enforcing or attempting to
enforce the Loan Documents, as to which the Borrower shall be obligated to pay
all reasonable attorneys' fees and other costs incurred by the Bank, in addition
to reimbursing the Bank for reasonable attorneys' fees, not to exceed $4,500, in
connection with making the Loans).

         13.2 The Borrower acknowledges that the Bank has and shall have the
right, upon an Event of Default, or any event which with the giving of notice or
lapse of time, or both, would constitute an Event of Default, to set off any
indebtedness from time to time owing to the Borrower by the Bank, including any
indebtedness represented by any account maintained with the Bank by the
Borrower, against any indebtedness that shall at any time be due and payable by
the Borrower to the Bank.

         13.3 Each and every right granted to the Bank hereunder or under any
other document delivered hereunder, or in connection herewith, or allowed it by
law or equity, shall be cumulative and may be exercised from time to time. No
failure on the part of the Bank to exercise, and no delay in exercising, any
right shall operate as a waiver thereof or as a waiver of any other right. No
single or partial exercise by the Bank of any right or remedy shall preclude any
other future exercise of it or the exercise of any other right or remedy. No
waiver or indulgence by the Bank of any default shall be effective unless in
writing and signed by the Bank, nor shall a waiver on one occasion be construed
as a bar to or waiver of that right on any future occasion. This Agreement may
not be amended except by a writing signed by all the parties hereto.

         13.4 The relationship between the Borrower and the Bank is solely that
of borrower and lender. The Bank has no fiduciary responsibilities to the
Borrower as a result of this Loan Agreement, the Loan Documents or the
consummation of the transactions contemplated hereby or thereby. The Bank does
not undertake any responsibility to the Borrower to review or inform the
Borrower of any matter in connection with any phase of the Borrower's business
or operations. The Borrower shall rely entirely upon its own judgment with
respect to its business, and any review, inspection, supervision, or information
supplied to the Borrower by the Bank is for the protection of the Bank and
neither the Borrower nor any third party is entitled to rely thereon.

         13.5 This Agreement is made in the State of Michigan. The validity of
this Agreement, and the validity of any documents incorporated herein or
executed in connection herewith, and the construction, interpretation and
enforcement thereof, and the rights of the parties thereto, shall be determined
under and construed in accordance with the internal laws of the State of
Michigan, without regard to principles of conflicts of law.

         13.6 Any and all notices or other communications required or permitted
under this Agreement shall be in writing, and shall be served either personally
or by certified United States mail with postage thereon full prepaid addressed
to the Borrower as:

                  Riviera Tool Company
                  5460 Executive Parkway
                  Grand Rapids, Michigan 49512

         and to the Bank as:

                  Old Kent Bank
                  One Vandenberg Center
                  Grand Rapids, MI 49503
                  Attention:  Gilbert A. Segovia, Vice President

or such other place or places as any party shall designate by written notice
served upon other parties.

         13.7 This Agreement shall be binding upon and shall inure to the
benefit of the Borrower and the Bank and their respective successors and
assigns; provided, however, the Borrower may not assign, transfer, hypothecate
or otherwise dispose of its rights hereunder or in connection herewith or any
interest herein (voluntarily, by operation of law, as security, by gift or
otherwise) without the prior written consent of the Bank, which consent may be
withheld in the sole discretion of the Bank. There are no third party
beneficiaries of this Agreement. The Bank may assign, negotiate, pledge or
otherwise hypothecate all or any portion of this Agreement, or grant
participations herein and in the Loan Documents, or in any of its rights or
security hereunder or thereunder, including, without limitation, the instruments
securing the Borrower's obligations hereunder, provided, however, that the Bank
promptly will inform the Borrower of any such assignment, negotiation, pledge or
other hypothecation and of the parties involved therewith and, provided further,
that no such assignment, negotiation, pledge or other hypothecation by the Bank
will relieve the Bank of its obligation under this Agreement. In connection with
any assignment or participation, the Bank may disclose to the proposed assignee
or participant any information that the Borrower is required to deliver to the
Bank pursuant to this Agreement. Notwithstanding the foregoing, the Bank shall
not assign all or any portion of its right or interest under the Loan Documents
to Bank One or any person who is a successor in interest to Bank One. The
Borrower acknowledges that the Bank has granted a participation in the Revolving
L/C Loan and the Existing Equipment Term Loan to be made pursuant to this
Agreement, and in all related Loan Documents, to Norwest Bank Minnesota,
National Association, and the Borrower consents thereto.

         13.8 The Borrower waives and releases any and all right that it may
have to require that the Bank marshal any of the collateral in which it holds an
interest as security for a loan made pursuant to this Agreement. The Borrower
shall upon the request of the Bank promptly execute and deliver to the Bank a
written statement, in form and substance reasonably satisfactory to the Bank,
identifying all of the collateral in which the Bank holds an interest as
security for a loan made pursuant to this Agreement. The Bank may file or record
such written statements in the appropriate public records as determined by the
Bank in its sole and absolute discretion.

         13.9 Upon any change in generally accepted accounting principles that,
if reflected in the financial statements or covenants required or established in
this Agreement, would have a material effect on such statements or covenants,
either party may request that the parties enter into negotiations to amend the
financial covenants or other terms of this Agreement so as to equitably reflect
such changes with the desired result that the criteria for evaluating the
Borrower's financial condition shall be the same after such changes as if the
changes had not been made.

         13.10 Should any part, term or provision of this Agreement, or of any
documents incorporated herein or executed in connection herewith, be determined
by the courts to be illegal, unenforceable or in conflict with any law of the
State of Michigan, federal law or any other applicable law, the validity and
enforceability of the remaining portions or provisions of such document(s) shall
not be affected thereby.

         13.11 The Borrower shall execute any and all additional or supplemental
documentation, and provide such further assistance and assurances as the Bank
may reasonably require, to give full effect to the terms, conditions and
intentions of this Agreement.

         13.12 Time is of the essence with respect to all provisions of this
Agreement.

         13.13 The headings in this Agreement have been inserted for convenience
only and shall not affect the meaning or interpretation of this Agreement.

         13.14 This Agreement may be executed in one or more counterparts, each
of which shall be considered an original and all of which shall constitute the
same instrument.

         13.15 This Agreement contains the entire agreement of the parties
hereto with respect to the subject matter hereof. The parties hereto shall not
be bound by any other different, additional or further agreements or
understandings except as consented to in writing by them.

         13.16 The Recitals are incorporated into and form a part of this
Agreement.

         13.17 The Bank and the Borrower, 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 Borrower shall seek to consolidate, by
counterclaim or otherwise, any such action in which a jury trial has been waived
with any other action in which a jury trial cannot be or has not been waived.
These provisions shall not be deemed to have been modified in any respect or
relinquished by either the Bank or Borrower except by a written instrument
executed by both of them.



         IN WITNESS WHEREOF, the parties have executed this Agreement as of the
day and year first above written.

         THIS NOTE HAS BEEN EXECUTED AND DELIVERED PURSUANT TO THE FIRST
         RESTATED LOAN AGREEMENT BETWEEN THE BORROWER AND THE BANK DATED AS OF
         AUGUST 31, 1999; SUCH LOAN AGREEMENT, TOGETHER WITH ALL FUTURE
         AMENDMENTS, RENEWALS AND REPLACEMENTS THEREOF, IF ANY, IS REFERRED TO
         AS THE "LOAN AGREEMENT"). REFERENCE IS MADE TO THE LOAN AGREEMENT FOR,
         AMONG OTHER THINGS, A STATEMENT OF THE OCCURRENCES WHICH MAY CONSTITUTE
         AN EVENT OF DEFAULT UNDER THIS NOTE.


                          $1,000,000.00 TERM LOAN NOTE
                                  (Fixed Rate)


$1,000,000.00                                                    August 31, 1999

         For value received, RIVIERA TOOL COMPANY, a Michigan corporation (the
"Borrower"), promises to pay to the order of OLD KENT BANK, a Michigan banking
corporation (the "Bank"), the principal sum of ONE MILLION AND NO/100 DOLLARS
($1,000,000.00), plus interest on the outstanding principal indebtedness
evidenced hereby from time to time at the rate of 8.04% per year, simple
interest, except during default.

         Following maturity or acceleration of the indebtedness evidenced by
this Note, the interest rate on the entire principal balance of this Note shall
be 300 basis points higher than the interest rate otherwise in effect. In
addition, if any payment required hereby is not made within 15 days of its due
date, the Borrower shall be liable for a late payment charge in an amount equal
to five (5%) percent of the monthly payment due, except that in no event shall
the late payment charge exceed $2,000.00. The late payment charge shall apply
individually to all payments past due, without proration. All such default
interest and late payment charges, if any, shall be paid upon demand by the
holder hereof.

         The indebtedness evidenced by this Note, unless sooner prepaid or
accelerated as provided in the Loan Agreement, shall be paid in monthly
installments of principal in the amount of SIXTEEN THOUSAND SIX HUNDRED
SIXTY-SIX AND 66/100 DOLLARS ($16,666.66) each (except that the principal
payment due on the scheduled maturity date of this Note shall be an amount equal
to the then outstanding principal balance of the indebtedness evidenced by this
Note) plus accrued and unpaid interest on the outstanding principal balance of
the indebtedness evidenced by this Note. Such payments of principal and interest
shall be due and payable on the first (1st) day of each month, beginning October
1, 1999. The principal balance of the indebtedness represented by this Note, and
all accrued and unpaid interest thereon, shall in any event be due and payable
on September 1, 2004, unless sooner accelerated by the Bank pursuant to the Loan
Agreement.

         The indebtedness evidenced by this Note may be prepaid in whole or in
part on one (1) Business Day's notice; provided that, in addition to all
principal, interest and costs owing at the time of prepayment, there shall be
due and owing from the Borrower a prepayment premium in an amount equal to:

                  (a)      Three percent (3%) of any principal prepayment made
                           on or prior to August 31, 2002;

                  (b)      Two percent (2%) of any principal prepayment made on
                           or after September 1, 2002 and prior to September 1,
                           2003;

                  (c)      One percent (1%) of any principal prepayment made on
                           or after September 1, 2003 and prior to September 1,
                           2004.

         Notwithstanding the foregoing, the Borrower shall not be obligated to
pay a prepayment premium if the indebtedness evidenced by this Note is prepaid
after acceleration by the Bank.

         All payments hereunder shall be made in lawful money of the United
States of America to the Bank at its principal office in Grand Rapids, Michigan,
or at such other place as the holder hereof may from time to time specify.

         Upon the occurrence of an Event of Default under the Loan Agreement
that has not been cured after notice and within the applicable grace period set
forth in the Loan Agreement, the entire principal balance of this Note remaining
at that time unmatured,



                                       48
<PAGE>   27

together with all accrued interest thereon, shall, at the election of the holder
hereof and without notice of such election and without demand or presentment,
become immediately due and payable, anything contained herein or in any other
document or instrument to the contrary notwithstanding.

         Neither the failure of the holder hereof promptly to exercise its right
to declare the outstanding principal and accrued and unpaid interest and other
charges hereunder to be immediately due and payable, nor failure to exercise any
other right or remedy the holder may have for default, nor the acceptance by the
holder of late or partial payments, nor the failure of the holder to demand
strict performance of any obligation of the Borrower hereunder, shall constitute
a waiver of any such rights while such default continues, nor a waiver of any
such rights in connection with any future default on the part of the Borrower
hereunder. Further, acceptance by the holder of partial payments following due
acceleration of the indebtedness evidenced hereby shall not constitute a waiver
by the holder of the acceleration of such indebtedness or of any other right or
remedy otherwise available to the holder in such circumstance.

         The Borrower waives presentment, protest and demand, notice of protest,
demand, dishonor and nonpayment of this Note.

         The Borrower agrees to pay all costs incurred by the holder, including
without limitation costs of collection and reasonable attorney's fees, in case
the principal of this Note or any payment of interest thereon is not paid at the
respective due date or maturity thereof, or in case it becomes necessary to
protect the security for this Note, whether suit is brought or not, or in case
of any other default under this Note.

         Any payment (including prepayments) upon this Note shall be applied
first to any expenses, charges or fees then due and payable to the Bank in
connection with the indebtedness evidenced hereby or any collateral for such
indebtedness, then to any accrued and unpaid interest hereunder, and then to the
unpaid principal balance.

         All payments due under this Note shall be paid by automatic deduction
of the amount due from account number 750-599-947-9 maintained by the Borrower
at the Bank. The Borrower irrevocably authorizes the Bank to make such
deductions when such payments are due.

         In no event shall the Borrower be required to make any payment
hereunder which would violate any applicable law regulating or limiting the rate
of interest that the holder of the Note may lawfully charge or collect. In the
event any such payment is made by or for the account of the Borrower, such
payment shall, to the extent it exceeds the maximum payment that the holder
hereof lawfully may charge or collect, be applied toward reduction of the
principal balance hereof.

         This Note is secured by a first lien on certain of the Borrower's
accounts receivable, machinery, equipment, furniture and fixtures, as set forth
in the Loan Agreement and in one or more Security Agreements between the Bank
and the Borrower dated June 12, 1997, all of which are incorporated herein by
reference.

         This Note shall be governed by and enforced and construed in accordance
with the laws of Michigan. The invalidity, illegality or unenforceability of any
one or more of the provisions hereof shall not affect the validity, legality or
enforceability of the remaining provisions hereof, all of which shall remain in
full force and effect.
