forth in Section 9 of this Agreement, and so long as there shall not have
occurred any event of default as defined in Section 8 of this Agreement, or any
event that with the giving of notice or lapse of time, or both, would be an
event of default, Bank shall extend to Borrower loans or provide lease financing
for the acquisition of new machinery and equipment (the "EQUIPMENT LOANS") in
aggregate amounts not to exceed $1,500,000 (the "EQUIPMENT LOAN COMMITMENT"). If
the aggregate principal amount of the Equipment Loans outstanding under the

cost of the machinery and equipment purchased.

         3.2.4    Each Equipment Loan shall be evidenced by and payable with
interest in accordance with the terms of a promissory note in the form attached
to this Agreement as SCHEDULE 3.2.4 (the "EQUIPMENT NOTE"), which Borrower shall
sign and deliver to Bank in connection with each advance, provided, however;
that each Equipment Loan in the form of lease financing shall be evidenced by
Bank's standard form of lease financing documents.

         3.2.5    As Bank extends each advance of the Equipment Loans to
Borrower, the amount of the Equipment Loans available to be disbursed in the
future under the Equipment Loan Commitment shall be reduced by the amount of
each advance. The amount of the Equipment Loans available to be disbursed under
the Equipment Loan Commitment shall be increased by the amount of the principal
payments made on Equipment Loans.

         3.2.6    Unless sooner terminated pursuant to Section 8 of this
Agreement, Bank's obligation to extend the Equipment Loans shall expire on March
31, 2002.

         3.2.7    Borrower shall have the right to prepay the Equipment Loans at
any time without penalty.

                  3.       responds to two-digit, year-date input in a way that
         correctly resolves the ambiguity as to century in a disclosed, defined

                  4.       stores, processes and provides output of date
         information in ways that are unambiguous as to century.

         10.2     Borrower shall pay, or reimburse Bank for, all out-of-pocket
expenses incurred by Bank (including, but not limited to, recording and filing
fees, search fees, title insurance premiums and fees and expenses of legal
counsel, other professional advisers, consultants and experts) in connection
with (i) the negotiation, preparation and signing of the Loan Documents, any
amendments to, or waivers of any provisions of, the Loan Documents and any
refinancing or restructuring of any Bank Indebtedness; (ii) the administration
of this Agreement and the other Loan Documents, including, without limitation,
making filings and recordings in public offices to perfect or give notice of
liens in favor of Bank, obtaining policies of title insurance, title searches,
financing statement searches, tax lien searches, appraisals and environmental
inspections, audits and assessments (iii) obtaining advice of counsel or other
professional advisers, consultants and experts regarding any aspect of the Loan
Documents or any Bank Indebtedness; (iv) the enforcement of any of the
provisions of the Loan Documents; (v) the collection of any Bank Indebtedness;
and (vi) the foreclosure of any security interests, mortgages or other liens
that at any time secure any Bank Indebtedness. Without limiting the generality
of the foregoing, Borrower shall pay Bank's standard fees for audits,
inspections and other activities that Bank conducts pursuant to Section 6.1.5 of
this Agreement. Bank's current audit fee is $500 per auditor per day. Bank may
at any time in its sole discretion, upon 30 days' notice to Borrower, change its
audit fee. Each fee and expense reimbursement that Borrower is obligated to pay
to Bank under this Section shall be due and payable within ten days after Bank
sends Borrower an invoice for it. Without limiting the generality of any other
Sections of this Agreement, if Borrower does not pay the invoice when due, then
Bank may, on the next Interest Payment Date, debit the Interest Payment Account
for the amount of the fee or expense reimbursement. "INTEREST PAYMENT ACCOUNT"

the Loans, and "INTEREST PAYMENT DATE" means each date on which interest on the
Loans is due and payable.

including, without limitation, any indebtedness represented by any deposit
accounts maintained with Bank by Borrower, against any indebtedness that shall
at any time be due and payable by Borrower to Bank.

         10.4     Upon signing this Agreement, Borrower shall pay to Bank a
nonrefundable commitment fee in the amount of Five Thousand Dollars ($5,000.00),
receipt of which is hereby acknowledged.

         10.5     Each right and remedy granted to Bank in this Agreement or in
any other Loan Document or allowed to Bank by law shall be cumulative and may be
exercised from time to time. No failure on the part of Bank to exercise, and no
delay in exercising, any right or remedy shall be a waiver of it or of any other
right or remedy.

         10.6     The relationship between Borrower and Bank under this
Agreement and the other Loan Documents is solely that of debtor and creditor.
Bank has no fiduciary responsibilities to Borrower. Bank does not and shall not
have any responsibility to review, or to inform Borrower of any matter in
connection with, any aspect of Borrower's business, operations or properties.
Borrower shall rely entirely upon its own judgment with respect to its business
and properties. Any review, appraisal, audit, inspection, survey, report or
other information obtained by Bank, whether or not paid for by Borrower or
furnished to it ("BANK INFORMATION"), is solely for the benefit of Bank. Neither
Borrower nor any third party is entitled to rely on any Bank Information. Bank
has no duty to Borrower with respect to any Bank Information, including, without
limitation, any duty to assure that any review, audit, survey, inspection or
appraisal is performed properly or any duty to disclose to Borrower any facts,
information, opinions, conclusions or statements contained in any review, audit,
inspection, survey, appraisal or other Bank Information.

         10.7     Borrower shall indemnify Bank with respect to all losses,
damages, liabilities, and expenses (including attorneys' fees) incurred by Bank
by reason of any failure of Borrower or Guarantor to comply with any of its
obligations under this Agreement or any of the other Loan Documents or by reason
of any warranty or representation made by Borrower to Bank in any of the Loan
Documents being false in any material respect.

         10.8     This Agreement and the other Loan Documents contain the entire
agreement of Borrower and Bank, and neither Borrower nor Bank has made any other
agreement, commitment, promise, warranty or representation to the other. No
provision of the Loan Documents may be modified, supplemented or waived except
by a writing signed by an authorized officer of Bank.

         10.9     This Agreement and the rights and obligations of the parties
under it shall be governed by and interpreted in accordance with the laws of the
State of Michigan. Any action arising out of or related to this Agreement or any
other Loan Document may be brought in any state or federal court having
jurisdiction over Oakland County, Michigan, that has jurisdiction of the subject
matter, and Borrower irrevocably consents and submits to the personal
jurisdiction of that court.

         10.10    Any notice or other communication required or permitted under
this Agreement shall be in writing, and shall be served either personally, by
telecopier or by certified United States mail with postage fully prepaid, or by
