                            1. GENERAL LENDING TERMS

         The following are the general terms of the loans to be made under this
Agreement:


         (a) A revolving line of credit for each Borrower (the "Revolving
             Loans") up to the lesser of the sum the respective Borrower's
             "Borrowing Base" (defined below) or $11,000,000 for McInnes and
             $1,714,330 for Erie (the "Revolving Advance Limits"), with
             Revolving Loans based on Eligible Inventory not to exceed
             $5,600,000 for McInnes and $400,000 for Erie; provided that in the
             aggregate for all Borrower's, Revolving Loans based upon Eligible
             Inventory shall not exceed $6,000,000 and aggregate Revolving Loans
             against Eligible Inventory which is work in process shall not
             exceed $2,250,000 in the aggregate or $70,000 for Erie and
             $2,180,000 for McInnes. The "Borrowing Base" for each Borrower is
             initially 85% of the aggregate outstanding amount of such
             Borrower's Eligible Accounts plus 65% of the aggregate value of raw
             materials which are Eligible Inventory, plus 65% of the aggregate
             value of finished goods which are Eligible Inventory plus the
             Applicable WIP Rate times the aggregate value of work in process
             which is Eligible Inventory. The advance rate against Eligible
             Accounts for each Borrower will reduce by one percentage point for
             each percentage point (or fraction thereof) that Dilution exceeds
             5% for that Borrower. Revolving Loans will be advanced to each
             individual Borrower subject to the forgoing formula.

         (b) A $10,688,040 term loan to McInnes and a $1,597,680 term loan to
             Erie (collectively, the "Term Loans").

         (c) Subject to Section 3.8 below, the applicable interest rate (prior
             to an Event of Default) on all Revolving Loans is three-quarters of
             one percent (0.75%) per annum in excess of the Prime Rate and on
             all other Loans, one and one-quarter percent (1.25%) per annum in
             excess of the Prime Rate (the forgoing interest rates are referred
             to as the "Base Rates" or a "Base Rate", as applicable). All
             interest shall be payable monthly in arrears on the first day of
             each month.

         (d) All Loans are guaranteed by each Borrower, are subject to Validity
             Certificates executed by George E. Wells and Timothy M. Hunter (the
             "Validity Certificators") and the Guaranty of Centrum Industries,
             Inc., Eballoy

             Glass Products Company, McInnes Services, Inc. and McInnes
             International, Inc. (the "Guarantors").

         (e) Unless renewed as provided in Section 3.2 below and absent prior
             termination under the terms of this Agreement, this Agreement
             expires on June 30, 2002 (the "Initial Term").

         (f) Borrowers shall pay Lender a loan origination fee of $250,000,
             payable one-half on the date of the first Revolving Loans made
             hereunder and the remaining one-half on December 31, 2000; the
             foregoing fee shall be deemed fully earned on the date of this
             Agreement and the unpaid portion shall be part of the Obligations
             and shall accrue interest from and after the date such installment
             is due if not timely paid. Borrowers shall receive a credit against
             the due diligence fee as provided in Lender's proposal letter dated
             February 10, 2000.

                  (1) The Account is valued at its face amount and represents a
             completed, bona fide transaction for Eligible Inventory sold,
             delivered, and accepted by the Account Debtor or for services
             rendered (but excluding any amounts in the nature of a service
             charge added to the amount due on an invoice because the invoice
             has not been paid when due) that requires no further act under any
             circumstances on the part of the Borrower or any other person or
             entity to make such Account payable by the Account Debtor, and the
             Account arises from an arm's-length transaction in the ordinary
             course of the Borrower's business between the Borrower and an
             Account Debtor that is not an affiliate, partner, officer, or
             employee of a Borrower, a member of the family of any partner,
             officer, or employee of a Borrower, or one of the other Borrowers.

                  (2) The Account is not unpaid more than 90 days from the date
             on which the original invoice rendered in connection with such
             Account was issued.

                  (3) The goods the sale of which gave rise to the Account were
             shipped or delivered or provided to the Account Debtor on a final
             sale basis and not on a bill and hold sale basis (unless subject to
             an agreement with the Account Debtor in form and substance
             acceptable to Lender), a consignment sale basis, a guaranteed sale
             basis, a sale or return basis or on the basis of




                                       3
<PAGE>   4

             any other similar understanding, and no part of such goods have
             been returned or rejected.

                  (4) The Account is not evidenced by chattel paper or an
             instrument of any kind.

                  (5) The Account Debtor with respect to the Account (A) is not
             insolvent, (B) is not the subject of any bankruptcy or insolvency
             proceedings of any kind or of any other proceeding or action,
             threatened or pending, which might have a materially adverse effect
             on its business, and (C) is not, in Lender's reasonable discretion,
             deemed ineligible for credit for other reasons (including, without
             limitation, unsatisfactory past experience of Borrower or Lender
             with the Account Debtor or unsatisfactory reputation of the Account
             Debtor).

                  (6) The Account Debtor is located within the United States of
             America or Ontario, Canada (or if located in another country or
             province, the Account is covered by credit insurance or a letter of
             credit assigned and acceptable to Lender or is backed by the
             guaranty of a U.S. based parent company in form acceptable to
             Lender).

                  (7) (A) The Account Debtor is not the government of the United
             States of America, or any department, agency or instrumentality
             thereof, or (B) if the Account Debtor is an entity mentioned in the
             preceding clause, the Federal Assignment of Claims Act (or
             applicable similar legislation) has been fully complied with so as
             to validly perfect Lender's first-priority security interest to
             Lender's satisfaction.

                  (8) The Account is a valid, legally enforceable obligation of
             the Account Debtor with respect thereto and is not subject to any
             dispute, condition, contingency, setoff, recoupment, reduction,
             claim for credit, allowance, adjustment, counterclaim or defense on
             the part of such Account Debtor, and no fact exists that may
             provide a basis for any of the foregoing in the present or future
             (however such Account will only be ineligible to the extent of such
             dispute, condition, contingency, setoff, recoupment, etc.).

                  (9) The Account is subject to a first-priority security
             interest in Lender's favor and is not subject to any other lien,
             claim, encumbrance, or security interest whatsoever.

                  (10) The Account is evidenced by an invoice or other
             documentation in form reasonably acceptable to Lender and arises
             from a contract, purchase order, or release that is satisfactory in
             form and substance to Lender.

                  (11) The Borrower has observed and complied with (A) all
             applicable laws of the United States of America (including the Fair
             Labor Standards Act) and (B) all laws of the state and country in
             which the Account





                                       4
<PAGE>   5

             Debtor or the Account is located which, if not observed and
             complied with, would deny to the Borrower access to the courts of
             such state.

                  (12) No material representation or warranty contained in this
             Agreement or any other agreement between the Borrower and Lender,
             or in any Borrowing Base Certificate with respect to such Account
             has been breached.

                  (13) The Account is not subject to any provision prohibiting
             its assignment.

                  (14) The Account does not represent any manufacturer's or
             supplier's credits, discounts, incentive plans, or other similar
             arrangements entitling the Borrower to discounts on future
             purchases.

                  (15) The Eligible Inventory giving rise to the Account was
             not, at the time of sale thereof, subject to any lien or
             encumbrance except in Lender's favor.

                  (16) The Account is payable in freely transferable United
             States Dollars.

             In addition to the foregoing requirements, Accounts of any Account
             Debtor that are otherwise qualified will be reduced to the extent
             of (1) any accounts payable (including, without limitation,
             Lender's good faith estimate of any contingent liabilities) by the
             Borrower to such Account Debtor ("Contras") and (2) that portion of
             an Account representing a retainage or holdback by the Account
             Debtor; provided that Lender, in its reasonable discretion may
             determine that none of such Accounts are Eligible Accounts if
             Contras represent 10% or more of the amount owing to all or any of
             the Borrowers from such Account Debtor. Finally, all Accounts owing
             by a given Account Debtor will be ineligible if more than 50% of
             the total Accounts owing by such Account Debtor to all or any of
             the Borrowers are otherwise ineligible.

             Any Account that is at any time an Eligible Account and that
             subsequently fails to meet any of the requirements set forth above
             will immediately cease to be an Eligible Account and must be
             removed from the Borrowing Base immediately.

             "ELIGIBLE INVENTORY" means that portion of each Borrower's
Inventory consisting of finished goods Inventory in respect of which no further
manufacturing, processing, or other work has to be done (other than packaging or
crating for shipment or distribution), raw materials held for use in the
ordinary course of each Borrower's business in manufacturing finished goods
Inventory and work in process Inventory being manufactured or processed that is
listed on a Borrowing Base Certificate delivered to Lender in accordance with
this Agreement that Lender determines in its reasonable discretion to be
Eligible Inventory. Without limiting the generality of the immediately preceding
sentence, no Inventory will be Eligible Inventory unless it meets all the
following minimum requirements:




                                       5
<PAGE>   6


                           (1) The Inventory has not been shipped, delivered,
                  provided to, purchased or sold by the Borrower on a bill and
                  hold, consignment sale, guaranteed sale, or sale or return
                  basis, or any other similar basis or understanding.

                           (2) No Account has arisen with respect to such
                  Inventory.

                           (3) The Inventory has not been billed to a customer
                  on a "progress billing" or similar basis prior to shipment to
                  the customer.

                           (4) The Inventory is valued at the lower of cost or
                  market, on a first-in-first-out basis.

                           (5) The Inventory is in the Borrower's possession, or
                  if the Inventory is located on premises not owned by the
                  Borrower, the landlord or owner of such premises must have
                  waived its distraint, lien, and similar rights with respect to
                  such Inventory and must have agreed in a written agreement
                  satisfactory to Lender (an "Acceptable Bailee Agreement")
                  providing the following: (A) that Lender has a valid,
                  perfected first priority security interest in the Inventory,
                  (B) to give Lender notice of any default by the Borrower and
                  the option to cure such default, (C) to permit Lender to enter
                  such premises to repossess or remove the Inventory at any
                  time, and (D) to grant Lender such other rights as Lender may
                  reasonably request. Notwithstanding the foregoing, assignments
                  of Borrowers' existing lender's bailee agreements shall
                  constitute Acceptable Bailee Agreements through July 31, 2000;
                  thereafter, Borrowers must obtain replacement Acceptable
                  Bailee Agreements acceptable to Lender.

                           (6) The Inventory is not subject to any royalty,
                  copyright, trademark, trade name, or licensing arrangement, or
                  any law, rule, or regulation that could limit or impair
                  Lender's ability to exercise its rights with respect to such
                  Inventory.

                           (7) In case of finished goods Inventory and
                  work-in-process Inventory, if otherwise eligible, the

                  issued by the applicable customer and is an amount equal to
                  the quantity specified in such release, or (b) is in
                  quantities that do not exceed projected sales of such
                  Inventory over the succeeding 3 month period. To the extent
                  Inventory does not qualify to be Eligible Inventory under this
                  subparagraph, such Inventory will also not qualify to be
                  Eligible Inventory by classifying such Inventory as raw
                  materials or work-in-process.

                           (8) The Inventory is not packaging, labels, manuals
                  or supplies.

                           (9) The Inventory meets all standards imposed by any
                  governmental or agency, department, or division having
                  regulatory authority over such Inventory or its use or sale
                  including, without limitation, standards set forth in the Fair
                  Labor Standards Act.

                           (10) No material representation or warranty in this
                  Agreement, any other agreement between the Borrower and
                  Lender, or any Borrowing Base Certificate has been breached
                  with respect to such Inventory.

                           (11) The Inventory is not obsolete, is of good and
                  merchantable quality, and is readily salable in the ordinary
                  course of Borrower's business.

                           (12) The Inventory is subject to a first-priority
                  security interest in Lender's favor and is not subject to any
                  other lien or encumbrance.

                  Any Inventory that is at any time Eligible Inventory and that
                  subsequently fails to meet any of the requirements set forth

and all related property which is covered by any mortgages or deeds of trust

              3. LINE OF CREDIT, OTHER LOANS, INTEREST AND PAYMENTS

         3.1 REVOLVING LINE OF CREDIT. From time to time prior to the expiration
of the Initial Term, or any extension terms provided for in Section 3.2 below,
so long as an Event of Default has not occurred or if an Event of Default has
occurred, such Event of Default has been timely remedied, Lender will, in its
reasonable discretion and subject to the terms and conditions set forth in this
Agreement, make Revolving Loans to each Borrower in such amounts as Borrower may
request, provided that the aggregate principal amount of all Revolving Loans
shall not exceed the applicable Revolving Advance Limit, or such Borrower's
Borrowing Base.


                                       11

<PAGE>   12

         Lender shall not be obligated to make Revolving Loans to Borrower at
any time; each Revolving Loan which is made under this Agreement will be made at
the option of, and in the discretion of, Lender. The Revolving Loans will not be
evidenced by a promissory note and a copy of Lender's books and records related
to the Revolving Loans shall constitute prima facie evidence of the outstanding
amount of Revolving Loans.

         Unless otherwise agreed by Lender, should an Overadvance exist, the
applicable Borrower shall immediately make principal reduction payments of such
excess to Lender as are required to reduce the outstanding balance of the
Revolving Loans such that no Overadvance exists.

         Borrowers may request from time to time Revolving Loan advances by
submitting a signed, completed Borrowing Base Certificate to Lender, in each
case given no later than 11:00 a.m. (Southfield, Michigan time) on the Business
Day of the proposed Revolving Loan advance. Subject to the terms and conditions
of this Agreement, Lender will make the proceeds of each such requested
Revolving Loan advance available to the applicable Borrower on a daily basis.

         3.2 RENEWAL OF AGREEMENT. Unless Lender provides Borrowers at least 90
days written notice of its intention to not renew this Agreement after the
Initial Term or any annual anniversary thereafter, Lender will extend this
Agreement from year to year on the terms set forth in this Agreement and any
amendments to this Agreement.

         3.3 TERM LOANS. Simultaneously with the execution of this Agreement,
the Borrowers have obtained from Lender the Term Loan(s), which shall be
evidenced by promissory note(s) of the Borrowers (the "Term Notes") payable to
the order of and dated on the date of this Agreement. In addition to principal
payments called for by the Term Notes, until the principal balances of each Term
Loan are less than or equal to the amounts set forth on Schedule 3.3, each
Borrower shall be obligated to make additional principal payments on account of
the Term Notes equal to such Borrower's Excess Cash Flow, with such principal
payments due and payable within 120 days of end of the respective Borrower's
fiscal year end(s).

         3.4 TERMINATION PREMIUM. If this Agreement is terminated at any time
prior to March 31, 2002, Borrowers shall be obligated to pay Lender a
termination premium of $375,000 (the "Termination Premium"). The Termination
Premium will also be due and payable in connection with any termination of this
Agreement by Lender or by or on behalf of Borrower(s), whether voluntary or
involuntary, including upon an Event of Default which is not timely cured, and
including in connection with termination of this Agreement or payment of the
Obligations by any trustee or debtor-in-possession in any Insolvency Proceeding.
The Termination Premium is presumed to be a reasonable estimate of the amount of
damages sustained by Lender as a result of the early termination of this
Agreement and Borrowers agree that such amount is reasonable under the
circumstances currently existing. Notwithstanding the foregoing, no Termination
Premium shall be payable in connection with payments made from insurance
proceeds resulting from a casualty loss or payments from condemnation proceeds.

                                       12

<PAGE>   13


         3.5 CROSS-DEFAULTS AND CROSS-COLLATERALIZATION.  A default (and the
expiration of any applicable cure period) under any Loan or Note is a default
under all other Notes and Loans and under all Obligations. All Collateral
secures all Obligations.

         3.6 INTEREST RATES; DEFAULT INTEREST RATES. The aggregate outstanding
amount of all Obligations shall bear interest at the rates set forth in Section
1 above. The aggregate outstanding amount of all Obligations shall also bear
interest, from and after the occurrence of an Event of Default and without
constituting a waiver of any such Event of Default, at the rate of three percent
(3%) per annum above the otherwise applicable Base Rates. All interest payable
under the Loan Documents shall be computed on the basis of a three hundred sixty
(360) day year for the actual number of days elapsed, based on the aggregate
amount of the Obligations that are outstanding on each day. Interest shall
continue to accrue until all of the Obligations are paid in full.

         3.7 PAYMENTS. All payments, including any prepayments, by Borrowers on
account of principal, interest, fees, or other Obligations must be made without
setoff or counterclaim to Lender at the address specified on the first page of
this Agreement in lawful money of the United States of America and in
immediately available funds. If any payment under this Agreement or any Note
becomes due on a day other than a day which is a Business Day, its maturity will
be extended to the next succeeding Business Day, and with respect to payments of
principal and interest thereon, will be payable at the then-applicable rate
during such extension.

         3.8 CREDITING PAYMENTS. For the purpose of calculating Borrowing Base
availability for Revolving Loans, the receipt by Lender of any wire transfer or
electronic funds transfer of funds, check or other item of payment shall be
applied immediately to provisionally reduce the Obligations, but such receipt
shall not be considered a payment on account unless such wire transfer or
electronic funds transfer is of immediately available federal funds and is made
to the appropriate deposit account of Lender or unless and until such check or
other item of payment is honored when presented for payment. For the purpose of
calculating interest, the receipt by Lender of any check or other item of
payment shall be deemed to have occurred one (1) Business Day after the date
Lender actually receives such item of payment and as to any wire transfer or
electronic funds transfer, one (1) Business Day after the date Lender actually
receives such item of payment. In the event any check or other item of payment
is not honored when presented for payment, the Borrower shall be deemed not to
have made such payment. Notwithstanding anything to the contrary contained
herein, any wire transfer, electronic funds transfer, check or other item of
payment received by Lender after 1:00 p.m. Southfield time shall be deemed to
have been received by Lender as of the opening of business on the immediately
following Business Day.

         3.9 PAYMENT MECHANICS. As an administrative convenience to Borrowers to
ensure the timely payment of amounts owing by Borrowers to Lender under this
Agreement, Borrowers hereby request Lender to advance for the account of the
applicable Borrower an amount each month sufficient to pay interest accrued on
the principal amount of the Obligations during the immediately preceding month
and all monthly principal installments or other payments due under the Notes or
other Loan Document and, provided prior notice is given to Borrowers, amounts
from time to time sufficient to pay all fees and Expenses owing by the Borrowers
under this Agreement. Borrowers authorize Lender, in Lender's

                                       13

<PAGE>   14


sole discretion, to make Revolving Loans for Borrowers' accounts of a sum
sufficient each month to pay, on the due date thereof, all interest accrued on
the principal amount of the Obligations during the immediately preceding month
and all monthly principal installments or other payments due under the Notes or
other Loan Documents and sums from time to time sufficient to pay, on the due
date thereof, all fees and Expenses owing by such Borrower under this Agreement,
and Lender may apply the proceeds of each such Revolving Loan to the payment of
such interest, installments, fees and Expenses. Each such Revolving Loan shall
thereafter accrue interest at the rate then applicable under this Agreement.
Lender, however, shall not be obligated to make any such Revolving Loan and
Borrowers acknowledge that Lender will be particularly disinclined to do so if
an Event of Default or an Overadvance exists at the time of, or would result
from the making of, such Revolving Loan.

         3.10 ALLOCATION OF EXPENSES. Because of the interrelationship of the
Borrowers and the benefits to each Borrower of being a party to a consolidated
financing arrangement with Lender, Borrowers agree that Lender may allocate (and
in turn charge to any Borrower's Revolving Loans) all Expenses between the
Borrowers as Lender deems appropriate and any re-allocation between the
Borrowers shall have no effect on Lender's rights under this Agreement.

         3.11 BORROWERS' APPOINTMENT OF AGENT. Each Borrower hereby appoints
McInnes as its agent for purposes of requesting Loans, signing Borrowing Base
Certificates and providing Lender with any information requested by Lender in
connection with this Agreement and to receive any notices from Lender hereunder.
Each Borrower ratifies the acts of McInnes pursuant to this section and agrees
that Lender shall have the right to rely on certificates, requests, Borrowing
Base Certificates and other documents and information provided by McInnes in its
capacity as agent for all Borrowers with the same legal effect as if the same
were signed and/or delivered by the respective Borrower(s). The appointment of
McInnes as agent pursuant to this Section 3.11 is coupled with an interest and
shall be irrevocable until all Obligations are fully and finally paid.

                           4. CONDITIONS OF BORROWING

         Notwithstanding any other terms of this Agreement, Lender is not
required to make any Loan to the Borrowers under this Agreement unless all of
the following conditions are met at or prior to the time such Loan is made:

         4.1 REPRESENTATIONS TRUE. Each Borrower's representations and
warranties in this Agreement (and in all agreements referred to or executed in
connection with this Agreement) are true as of the date of each Loan or advance
under this Agreement with the same effect as though such representations and
warranties had been made by each Borrower at such time, except to the extent
such representations and warranties specifically relate to a prior date.

         4.2 NO DEFAULT. No Event of Default under this Agreement exists, nor
does any event exist which, upon the lapse of time, service of notice, or both,
would constitute an Event of Default under this Agreement, and no suit or
proceeding at law or in equity or of any governmental body has been instituted
or, to the knowledge of any Borrower,

                                       14

<PAGE>   15


threatened which, in either case, would materially and adversely affect any
Borrower's financial condition or business operations.

         4.3 COUNSEL OPINION.  Simultaneously with the execution of this
Agreement, Lender must have received from Borrowers a satisfactory legal
opinion.

         4.4 INITIAL EXCESS AVAILABILITY. In the aggregate, Borrowers have at
least $1,250,000 in excess Borrowing Base availability prior to the first
Revolving Loans to be made hereunder, net of the sum of all past due
liabilities, including accounts payable which are more than 45 days past written
due date.

         4.5 SUBORDINATED DEBT OR CAPITAL. If Borrower does not have the minimum
excess availability at closing required by Section 4.4 above, Borrower has
received additional equity or subordinated debt (which if in the form of debt,
must be subordinated to Lender's Obligations pursuant to a Subordination
Agreement in form and substance acceptable to Lender) to satisfy Section 4.4
above.


                         5. SECURITY FOR THE OBLIGATIONS

         5.1 GRANT OF SECURITY. Borrowers each hereby grant Lender a continuing
security interest in all of their respective presently existing and hereafter
acquired or arising Collateral to secure prompt repayment of all Obligations and
to secure the prompt performance by such Borrower of each of its covenants and
duties in this Agreement and any other agreements with Lender. Lender's security
interests in the Collateral shall attach to all Collateral without further act
on the part of Lender or Borrowers. Other than sales of finished goods Inventory
to buyers in the ordinary course of business, or sales of obsolete or worn out
equipment having a book value of $50,000 or less in the aggregate in any fiscal
year, Borrowers have no authority, express or implied, to dispose of, sell or
transfer any of the Collateral.

         5.2 NEGOTIABLE COLLATERAL. In the event that any Collateral, including
proceeds, is evidenced by or consists of Negotiable Collateral, each Borrower
shall, upon the request of Lender, immediately endorse (without recourse) and
assign such Negotiable Collateral to Lender and deliver physical possession of
such Negotiable Collateral to Lender.

         5.3 ADDITIONAL DOCUMENTATION. At the request of Lender, each Borrower
shall execute and deliver to Lender, all financing statements, continuation
financing statements, fixture filings, security agreements, pledges,
assignments, endorsements of certificates of title, applications for title,
affidavits, reports, notices, schedules of accounts, letters of authority, and
all other documents that Lender may reasonably request, in form satisfactory to
Lender, to perfect and continue perfected Lender's security interest in the
Collateral and in order to fully consummate all of the transactions contemplated
hereunder and under the other Loan Documents.

         5.4 POWER OF ATTORNEY. Borrowers each hereby irrevocably designate,
make, constitute and appoint Lender (and any of Lender's officers, employees or
agents designated by Lender) as such Borrower's true and lawful
attorney-in-fact. Pursuant to this power of attorney, Lender, or Lender's agent,
may, without notice to Borrowers and in either

                                       15

<PAGE>   16


the name of the respective Borrower or Lender, but at the cost and expense of
such Borrower, at such time or times as Lender in its reasonable discretion may
determine: (a) demand payment of the Accounts from the Account Debtors, enforce
payment of the Accounts by legal proceedings or otherwise, and generally
exercise all of Borrower's rights and remedies with respect to the collection of
the Accounts; (b) take control, in any manner, of any item of payment or
proceeds relating to any Collateral; (c) upon the occurrence and during the
continuance of an Event of Default, prepare, file and sign Borrower's name to a
proof of claim in bankruptcy or similar document against any Account Debtor or
to any notice of lien, assignment or satisfaction of lien or similar document in
connection with any of the Collateral; (d) sign Borrower's name on any of
documents described in Section 5.3 or on any other similar documents to be

appointment of Lender as Borrower's attorney-in-fact and each and every one of
Lender's rights and powers, being coupled with an interest, is irrevocable until
all of the Obligations have been fully repaid and performed and this Agreement
has been terminated. Lender shall promptly provide Borrowers with copies of any
documents signed by Lender on any Borrower's behalf pursuant to this Section
5.4.

         5.5 RIGHT TO INSPECT. Lender, through any of its officers, employees or

<PAGE>   17


Business Records, to inspect and copy (by electronic or other means) any
Business Records in order to verify the amount or condition of, or any other

also shall have the right at any time or times during Lender's usual business

has occurred, Lender may conduct any of the inspections referenced in this
Section 5.5 at any time without regard to any Borrower's or any third party's
usual business hours.

                        6. REPRESENTATIONS AND WARRANTIES

         In order to induce Lender to make Loans as provided in this Agreement
and to accept any Notes, each Borrower represents and warrants to Lender as
follows:

         6.1 ORGANIZATION. The Borrower is a corporation duly organized and
existing under the laws of the State of its incorporation as set forth in the
preamble to this Agreement, and the execution, delivery and performance of the
Loan Documents, including this Agreement and the issuance of the Notes as
provided in this Agreement are within Borrower's corporate powers, have been
duly authorized, are not in contravention of law or the terms of the Borrower's
Articles of Incorporation or Code of Regulations or Bylaws, as applicable, and
do not require the consent or approval of any governmental body, agency or
authority. The Borrower is duly licensed or qualified to do business in all
jurisdictions in which the Borrower has substantial property or business
operations.

         6.2 FINANCIAL STATEMENTS. Borrower's balance sheets and the statements
of profit and loss and surplus furnished to Lender from time to time will be in
all material respects in accordance with generally accepted accounting
principles, consistently applied ("GAAP") and will fairly present Borrower's
financial condition as of the relevant dates and the results of its operations
for the applicable time periods.

         6.3 LIENS.  Except for Permitted  Liens,  the Borrower has good and
marketable title to all its assets, including all Collateral, free and clear of
all liens and encumbrances.

         6.4 ABSENCE OF CONFLICTING OBLIGATIONS. The making and execution of the
Loan Documents and compliance with its terms and the issuance of the Notes will
not result in a breach of any of the terms and conditions of or result in the
imposition of any lien, charge, or encumbrance upon any property of the Borrower
pursuant to, or constituting a default under, any indenture or other agreement
or instrument to which the Borrower is a party or by which it is bound.

         6.5 TAXES. Borrower has no outstanding unpaid tax liabilities (except
for taxes which are currently accruing from its current operations and ownership
of property, and which are not delinquent), and no tax deficiencies have been
proposed or assessed against Borrower. There have been no audits of Borrower's
federal income tax returns, which have resulted in or are likely to result in
the assessment of any material tax liability against Borrower and all taxes
shown by any returns have been paid.

         6.6 ABSENCE OF MATERIAL LITIGATION. The Borrower is not a party to any
litigation or administrative proceeding, nor so far as is known by the Borrower
is any litigation or
                                       17

<PAGE>   18


administrative proceeding threatened against it, which in either case would, if
adversely determined, cause any material adverse change in its properties or the
conduct of its business.

         6.7 ABSENCE OF ENVIRONMENTAL PROBLEMS. Except as disclosed in writing
to Lender, the Borrower is in substantial compliance with all Environmental Laws
involving Borrower's past or present operations, facilities and property
(provided that any non-compliance does not have a materially adverse affect on
Borrower, its assets or its business operations). Further, Borrower has not been
cited for violating any applicable Environmental Laws and Borrower has all
necessary environmental permits and licenses to operate its business.

         6.8 LEGAL NAME. Borrower's full legal name is exactly as set forth on
the signature page of this Agreement and, except as provided on Schedule 6.8,
Borrower has not changed its name since the date of its organization, nor has it
used any assumed name, tradename, or tradestyle.

         6.9 FINANCING STATEMENTS. Except for financing statements covering
Permitted Liens and Lender's liens, no financing statements covering any
Collateral, proceeds of Collateral, or any other of Borrower's property are on
file in any public office.

         6.10 ERISA.  No Reportable Event has occurred with respect to any Plan.

         6.11 BROKER'S FEES. Borrower has made no commitment, and has taken no
action, that could result in a claim for any brokers', finders', or similar fees
or commitments in respect to the transactions with Lender described in this
Agreement. Borrower agrees to pay all finders' fees or similar fees payable to
any persons or entities in connection with this Agreement and to defend and hold
Lender harmless against any and all such fees.

         6.12 PRINCIPAL EXECUTIVE OFFICE, BUSINESS LOCATION.

                  (a) Borrower's principal place of business, all physical
         Collateral, records concerning the Collateral and all other Business
         Records are located at or about the address set forth on Schedule 6.12
         (except for Inventory subject to an Acceptable Bailee Agreement); and

                  (b) Borrower will provide Lender with 30 days prior written
         notice of any change with respect to any of the foregoing.

         6.13 FULL DISCLOSURE. This Agreement and all of the Exhibits, Schedules
and other written material delivered by the Borrower to Lender in connection
with the transactions contemplated by this Agreement do not contain any
statement that is false or misleading with respect to any material fact and do
not omit to state a material fact necessary in order to make the statements
therein not false or misleading. There is no additional fact that the Borrower
is aware of that has not been disclosed in writing to Lender that materially
affects adversely or, so far as the Borrower can reasonably foresee, will
materially affect adversely the Borrower's financial condition or business
prospects.


                                       18

<PAGE>   19

         6.14 FLOOD HAZARD. Except for real estate subject to flood insurance
reasonably acceptable to Lender, no location at which the Borrower does business
falls within the boundaries of a special flood hazard area so designated by the
United States Federal Emergency Management Administration.

         6.15 INTELLECTUAL PROPERTY. To the best of Borrower's knowledge, the
Borrower owns or possesses adequate licenses or other rights to use all patents,
processes, trademarks, trade names, and copyrights necessary to conduct its
business as now conducted or presently intended to be conducted and the Borrower
has no reason to believe that any such rights conflict or will conflict with the
rights of others. All of Borrower's patents, trademarks and copyrights are
described in the Collateral Assignment of Intellectual Property and Security
Agreement executed by Borrower in favor of Lender in connection with this
Agreement.

         6.16 COMPLIANCE WITH LAW. Borrower is in substantial compliance with
all laws and regulations applicable to it, its business and properties (provided
that any non-compliance does not have a materially adverse effect on Borrower,
its assets or its business operations). To the best of Borrower's knowledge,
Borrower has all licenses, permits, orders and approvals that are required under
any governmental law or regulation in connection with the Borrower's business
and properties ("Permits"). No notice of any violation has been received with
respect of any Permits and no proceeding is pending or, to the best of the
Borrower's knowledge, threatened to terminate, revoke or limit any Permits.

         6.17 ACCOUNTS. All of Borrower's Accounts constitute bona fide existing
obligations created by the sale and delivery of Inventory or the rendition of
services to Account Debtors in the ordinary course of Borrower's business, and,
in the case of Accounts created by the sale and delivery of Inventory, the
Inventory giving rise to such Accounts has been delivered to the Account Debtor.
At the time of the creation of each Eligible Account or the assignment thereof
to Lender, each such Eligible Account is unconditionally owed to Borrower
without defense, dispute, offset, counterclaim or right of return or
cancellation and Borrower has not received notice of actual or imminent
bankruptcy, insolvency or material impairment of the financial condition of the
Account Debtor regarding such Eligible Account.

         6.18 LABOR MATTERS. No strikes or other labor disputes against Borrower
are pending or, to Borrower's knowledge, threatened. Hours worked by and payment
made to employees of Borrower have not been in violation of the Fair Labor
Standards Act or any other applicable federal, state, local or foreign law
dealing with such matters. All payments due from Borrower on account of employee
health and welfare insurance have been paid or accrued as a liability on the
books of Borrower. Except as set forth in Schedule 6.18, Borrower has no
obligation under any collective bargaining agreement, management agreement,
consulting agreement or any employment agreement. There is no organizing
activity involving Borrower pending or, to Borrower's knowledge, threatened by
any labor union or group of employees. Except as set forth in Schedule 6.18,
there are no representation proceedings pending or, to Borrower's knowledge, no
group of employees of Borrower has made a pending demand for recognition. Except
as set forth in Schedule 6.18, there are no complaints or charges against
Borrower pending or threatened to be filed where the amount at issue exceeds
$50,000 with any federal, state, local or foreign court,

                                       19

<PAGE>   20


governmental agency or arbitrator based on, arising out of, in connection with,
or otherwise relating to the employment or termination of employment by Borrower
of any individual.

         6.19 SUBSIDIARIES; OWNERSHIP. Except as set forth on Schedule 6.19,
Borrower has no subsidiaries and is not engaged in any joint venture or
partnership with any other person, or is an affiliate of any other person other
than the other Borrowers. All of the issued and outstanding stock of Borrower is
owned by the entity or individuals disclosed on Schedule 6.19. There are no
outstanding rights to purchase options, warrants or similar rights or agreements
pursuant to which Borrower may be required to issue or sell any stock or other
equity security.

         6.20 DEPOSIT ACCOUNTS. Schedule 6.20 lists all banks and other
financial institutions at which Borrower maintains deposits and/or other
accounts, including any disbursement accounts, and Schedule 6.20 correctly
identifies the name, address and telephone number of each depository, the name
in which the account is held, a description of the purpose of the account, and
the complete account number.

         6.21 CUSTOMER RELATIONS. There exists no actual or threatened
termination or cancellation of, or any material adverse modification or change
in: (a) the business relationship of Borrower with any customer or group of
customers whose purchases during the preceding twelve (12) months caused them to
be ranked among the ten largest customers of Borrower; or (b) the business
relationship of Borrower with any supplier material to the operations of
Borrower. The ratings ("Customer Ratings") assigned to Borrower by its customers
and any other applicable customer have not been withdrawn, rescinded or
downgraded in the past twelve (12) months, nor has Borrower received any notice
of any adverse action taken or proposed to be taken by any customer in respect
of any Customer Ratings.

         6.22 CUSTOMER SUPPLY PROGRAMS. Except as disclosed on Schedule 6.22,
Borrower does not participate in any resale, "off-load" or other programs under
which any of Borrower's customers (or any affiliates of any customer) sell or
supply raw materials, component parts or other inventory to Borrower, including
without limitation, on a bailment, consignment or another basis.

         6.23 INTEGRATED OPERATIONS. Borrower and the other Borrowers are a part
of an integrated group which share business operations, functions and services,
including sales, marketing, finance, accounting, management, manufacturing,
engineering, quality control and shipping. As a result of the foregoing,
Borrower will benefit in a direct and substantial way from Loans and advances
made by Lender to the other Borrowers and, but for Lender making Loans to the
other Borrowers and such other Borrowers being able to provide business services
to Borrower, Borrower's business operations would be materially and negatively
impacted.


                              7. NEGATIVE COVENANTS

         While any of the Obligations remain unpaid, each Borrower must not
agree to and must not (without Lender's prior written consent):

         a 24 month amortization); and

                            8. AFFIRMATIVE COVENANTS

         While any of the Obligations remain unpaid, each Borrower must at all
times:

         8.1      INSURANCE. Maintain adequate fire and extended coverage and
liability insurance covering all of its present and future real and personal
property, including the Collateral, with Lender's loss payable and
noncontributory mortgagee clauses in Lender's favor, protecting Lender's
interest, as such interest may appear, together with such policies of business
interruption insurance and products liability insurance as Lender may reasonably
request and insurance in accordance with all applicable workers' compensation
laws. Such insurance must be in such form, with such companies, and in such
amounts as is acceptable to Lender, insuring against liability for damage to
persons or property, and must provide for thirty (30) days prior written notice
to Lender of cancellation or material alteration. Borrower must provide Lender
with satisfactory evidence of insurance for all such coverages or upon Lender's
request true copies of the policies, simultaneously with the execution of this
Agreement, showing that Lender's interest has properly been endorsed on the
applicable policy. Lender may, in its sole discretion, on 30 days written notice
to the Borrower, require the Borrower to obtain additional or different
insurance coverages as Lender may reasonably request. Provided an Event of
Default has not occurred and is not continuing, Borrowers shall have the right
to settle and compromise casualty insurance claims and to use proceeds for (a)
repair or replacement of the damaged property and/or (b) repayment of the
Obligations. The provisions in the Mortgages, if any, with respect to Lender's
rights to retain insurance proceeds in the event of a casualty, are to be
treated as consistent with those contained in this paragraph.

         8.2      EXISTENCE; PAYMENT OF TAXES AND OTHER LIABILITIES. Maintain
its corporate existence and pay all taxes, assessments and other governmental
charges against it or its property, and all of its other liabilities, before the
same become delinquent and before penalties accrue on these debts and
obligations except to the extent and so long as the same are being contested in
good faith by appropriate proceedings in such manner as not to cause any
material adverse effect upon its financial condition, with adequate reserves
provided for such payments, and, upon demand by Lender, posting with Lender of
adequate security to protect Lender.

         8.3      ACCOUNTING RECORDS; REPORTS. Maintain a standard and modern
system for accounting in accordance with generally accepted accounting
principles consistently applied throughout all accounting periods, and furnish
to Lender:

                  (a) Within 15 calendar days after the end of each month, as of
         the last day of the preceding month, aging and summary reports of
         Accounts in such form and detail as Lender may reasonably request.

                  (b) On each Business Day, borrowing base certificates for each
         Borrower (each, a "Borrowing Base Certificate") as of the close of
         business of the preceding day in a form provided by Lender.

                  (c) Accounts receivable and collection reports, on a daily
         basis.

         inventory report covering all Inventory (wherever located), including
         raw material, work-in-process, and finished goods in such form and
         detail as Lender may reasonably request, accompanied by a certificate
         of an officer of the applicable Borrowers in form and substance
         acceptable to Lender.

                  (e) Within 10 Business Days of Lender's request, an Inventory
         report listing of all inventories of each Borrower including raw
         material, work-in-process and finished goods in such form and detail as
         Lender may reasonably request, accompanied by a certificate of an
         officer of such Borrower in form and substance acceptable to Lender.

                  (f) Within 30 calendar days after the end of each of the
         month, an internally prepared balance sheet of each Borrower as of the
         close of each such month and of the comparable month in the preceding
         fiscal year, and statements of income and surplus of the Borrower for
         each month and for that part of the fiscal year ending with each such
         month and for the corresponding period of the preceding fiscal year,
         all in reasonable detail and certified as true and correct (subject to
         audit and normal year-end adjustments) by an officer of the Borrower.

                  (g) As soon as available and in any event within 90 calendar
         days after the close of each fiscal year of Borrower, a copy of
         Centrum's audited financial statements and audit report, including
         consolidating financial statements showing each Borrower, as prepared
         by independent certified public accountants of recognized standing
         selected by the Borrower and reasonably acceptable to Lender, together
         with all management letters, to the effect that the financial
         statements fairly present the financial condition of the Borrower and
         the results of its operations as of the relevant dates, and each such
         financial statement shall, if available at a reasonable cost to
         Borrower, be accompanied by a certification by the public accountants
         that there exists no Event of Default or other action, condition or
         event which, with the giving of notice or lapse of time or both, would
         constitute an Event of Default under this Agreement, or if such
         condition does exist, stating the nature thereof and the action, if
         any, Borrower is taking to correct such condition.

                  (h) Within 90 calendar days after the end of each fiscal year
         of Borrower, a detailed schedule of all insurance policies which the
         Borrower had in force as of the end of such fiscal year, signed by an
         officer of the Borrower.

                  (i) (1) As soon as possible and in any event within 30
         calendar days after Borrower knows that any Reportable Event with

                                   9. DEFAULTS

         Without limiting the discretionary nature of Lender's agreement to make
Loans, if any one or more of the following events occurs (each an "Event of
Default" and collectively, "Events of Default"), then Lender's obligation to
make or accept any Note or any Loan under this Agreement will, at Lender's
option, immediately terminate, and the unpaid principal balance of, and accrued
interest on, all Obligations will be immediately due and payable, without
further notice of any kind, notwithstanding anything contained to the contrary
in this Agreement or in any other agreement, Note or document:

         9.1      DEFAULT IN PAYMENT OF OBLIGATIONS. Unless Lender, in its
discretion, elects to charge the Revolving Loans as provided in Section 3.9
above, any Borrower fails to make a payment of any principal or interest when
and as due on any Note or any other Obligations, including the Expenses.

         9.2      DEFAULT UNDER ANY AGREEMENTS. A default in the performance or
observance of any term, condition or covenant in this Agreement, or in any other
agreement or instrument made or given by any Borrower to Lender required to be
observed or performed by any Borrower for a period of 10 days after receipt of
written notice from Lender if such default or breach is curable.

         9.3      REPRESENTATIONS OR STATEMENTS FALSE. Any representation or
warranty made by any Borrower in this Agreement or any certificate delivered in
accordance with this Agreement, or any financial statement delivered to Lender
proves to have been false in any material respect as of the time when made or
given.

         9.4      DEFAULT ON OTHER DEBT. Any Borrower fails to pay all or any
part of the principal of or interest on any indebtedness of or assumed by such
Borrower for borrowed money as and when due and payable, whether at maturity, by
acceleration or otherwise, and such default is not cured within the period of
grace, if any, specified in the documents(s) evidencing such indebtedness, in
excess of $50,000 in the aggregate per fiscal year.

         9.5      JUDGMENTS. A judgment (which is not otherwise fully covered by
insurance) is entered against any Borrower which, together with other
outstanding judgments entered against any Borrowers, exceeds in the aggregate
$50,000, and remains outstanding and unsatisfied, unbonded or unstayed for 30
days after the date of entry of such judgment,



                                       26


<PAGE>   27


unless the judgment creditor commences enforcement action, in which case the
commencement of such enforcement action shall constitute an Event of Default.

         9.6      BANKRUPTCY; INSOLVENCY. Any Borrower: (a) dies or becomes
insolvent; or (b) is unable, or admits in writing its inability to pay debts as

property; or (d) files on its behalf or consents to an Insolvency Proceeding; or
(e) has an Insolvency Proceeding filed or instituted against it which is not
released or dismissed within 45 days; or (f) applies to a court for the
appointment of a receiver, trustee or custodian for any of its or their assets;
or (g) has a receiver, trustee or custodian appointed for any of its or their
assets (with or without their respective consent) which is not released or
dismissed within 45 days; provided, however as to subparagraphs (e) and (g),
Lender shall be under no obligation to make any Loans during the referenced 45
day period.

         9.7      REPORTABLE EVENT. If any Reportable Event occurs and continues
for 30 days or any Plan is terminated within the meaning of Title IV of ERISA,
or a trustee is appointed by the appropriate United States District Court to
administer any Plan, or the Pension Benefit Guaranty Corporation institutes
proceedings to terminate any Plan or to appoint a trustee to administer any
Plan.

         9.8      MATERIAL LOSS OR ADVERSE CHANGE. Any Borrower suffers: (i) a
casualty as to any material asset or assets used in the conduct of Borrower's
business which is not, except for deductibles acceptable to Lender, fully
covered by insurance conforming to the requirements of this Agreement; or (ii) a
material adverse change in any Borrower's business prospects or financial
condition.

         9.9      REVOCATION OF VALIDITY CERTIFICATE. If any present or future
Validity Certificator notifies Lender that it intends to terminate all or a
portion of its liability under any present or future Validity Certificate in
Lender's favor, disputes its liability under any present or future Validity
Certificate in Lender's favor, or defaults under any other agreement in Lender's
favor; provided, however, it shall not be an Event of Default if a Validity
Certificator dies or terminates his employment with Borrower if such Validity
Certificator is replaced within 90 days by a substitute reasonably acceptable to
Lender.

         9.10     DEFAULT UNDER OTHER DOCUMENTS. If any Borrower or any
subordinated creditor which is affiliated with Borrower which is party to any
agreement or instrument with or in favor of Lender entered into or delivered in
connection with the Loans or the Collateral defaults under any such agreement or
instrument and such default is not cured within the grace period, if any,
contained in such agreement or instrument.

         9.11     GOVERNMENT LIEN. A notice of lien, levy or assessment is filed
of record with respect to any of any Borrower's assets by the United States
government, or any department, agency or instrumentality thereof, or by any
state, county, municipal or other governmental agency, or any tax or debt owing
at any time hereafter to anyone becomes a lien, whether choate or otherwise,
upon a material portion of any Borrower's assets and the same is not paid on the
payment date thereof.




                                       27


<PAGE>   28

$250,000 in New Subordinated Debt by August 31, 2000.

                           10. REMEDIES ON OCCURRENCE
                             OF AN EVENT OF DEFAULT

         10.1     RIGHT AND REMEDIES. Upon the occurrence of an Event of Default
(not cured within any time or grace period specifically provided in Section 9),
Lender has all rights and remedies provided by law, and all such rights and
remedies granted under any guaranty agreement relating to the Obligations or any
security agreement or Mortgage relating to the Collateral, and under all other
existing and future agreements between Lender and the Borrowers. All such rights
and remedies are cumulative. Upon the occurrence of an Event of Default not
cured within any applicable cure period specifically provided for in Section 9
above, Lender may, at its election, without notice of its election and without
demand, do any one or more of the following, all of which are authorized by each
Borrower:

                  (a)      Declare all Obligations, whether evidenced by this
Agreement, a Note, any of the other Loan Documents or otherwise, immediately due
and payable in full;

                  (b)      Cease making Loans or advances under this Agreement,
any of the other Loan Documents or any other agreement between any Borrower and
Lender;

                  (c)      Terminate this Agreement and any of the other Loan
Documents as to any future liability or obligation of Lender, but without
affecting Lender's rights, security interests and mortgages in the Collateral
and without affecting the Obligations;

                  (d)      Settle or adjust disputes and claims directly with
Account Debtors for amounts and upon terms which Lender considers advisable and,
in such cases, Lender will credit the applicable Borrower's loan account with
only the net amounts received by Lender in payment of such disputed Accounts,
after deducting all Expenses incurred or expended in connection therewith;

                  (e)      Cause each Borrower to hold all returned Inventory in
trust for Lender, segregate all returned Inventory from all other property of
such Borrower or in such Borrower's possession and conspicuously label said
returned Inventory as being subject to Lender's security interest;

                  (f)      Without notice to or demand upon Borrowers or any
guarantor, make such payments and do such acts as Lender considers necessary or
reasonable to protect its security interest in the Collateral. Each Borrower
agrees to assemble the Collateral if Lender so requires and to deliver or make
the Collateral available to Lender at a place designated by Lender. Each
Borrower authorizes Lender to enter any premises where the Collateral is
located, to take and maintain possession of the Collateral, or any part of it,
and to pay, purchase, contest or compromise any encumbrance, charge or lien that
in Lender's determination appears to be prior or superior to its security
interest and to pay all expenses incurred in connection therewith. With respect
to any of any Borrower's owned premises,



                                       28



<PAGE>   29


each Borrower hereby grants Lender a license to enter into possession of such
premises and to occupy the same, without charge, in order to exercise any of
Lender's rights or remedies provided herein, at law, in equity, or otherwise;

                  (g)      Without notice to any Borrower (such notice being
expressly waived) and without constituting a retention of any Collateral in
satisfaction of an obligation (within the meaning of Section 9-505 of the
Uniform Commercial Code), hold or set off and apply to the Obligations any and
all (i) balances and deposits of any Borrower held by Lender (including any
amounts received in a lockbox or blocked account), or (ii) indebtedness at any
time owing to or for the credit or the account of any Borrower held by Lender;

                  (h)      Hold, or set off and apply, as cash collateral, any
and all balances and deposits of any Borrower held by Lender (including any
amounts received in a lockbox or blocked account) to secure the Obligations;

                  (i)      Ship, reclaim, recover, store, finish, maintain,
repair, prepare for sale, advertise for sale and sell the Collateral (in the
manner provided for herein). Lender is hereby granted a license and right to
use, without charge, each Borrower's labels, patents, copyrights, rights of use
of any name, trade secrets, trade names, trademarks, service marks, and
advertising matter, or any property of a similar nature, as it pertains to the
Collateral, in completing production of, advertising for sale and selling any
Collateral. Each Borrower's rights under all licenses and all franchise
agreements shall inure to Lender's benefit;

                  (j)      Sell the Collateral at either a public or private
sale, or both, by way of one or more contracts or transactions, for cash or on
terms, in such manner and at such places (including at each Borrower's premises)
as Lender determines is commercially reasonable. It is not necessary that the
Collateral be present at any such sale;

                  (k)      Lender shall give notice of the disposition of the
Collateral as follows:

                           (1)      Lender shall give the involved Borrower and
                  each holder of a security interest in the Collateral who has
                  filed with Lender a written request for notice, a notice in
                  writing of the time and place of public sale or, if the sale
                  is a private sale or some other disposition other than a
                  public sale is to be made, then the time on or after which the
                  private sale or other disposition is to be made;

                           (2)      The notice will be delivered to the involved
                  Borrower as provided in Section 12.8, at least ten Business
                  Days before the date fixed for the sale, or at least ten
                  Business Days before the date on or after which the private
                  sale or other disposition is to be made, unless the Collateral
                  is perishable or threatens to decline speedily in value.
                  Notice to persons other than the involved Borrower claiming an
                  interest in the Collateral shall be sent to such addresses as
                  they have furnished to Lender;

                  (l)      Lender may credit bid and purchase at any public
sale;



                                       29


<PAGE>   30



                  (m)      Any deficiency that exists after disposition of the
Collateral as provided above shall be paid immediately by the Borrowers. Any
excess will be remitted without interest by Lender to the party or parties
legally entitled to such excess; and

                  (n)      In addition to the foregoing, Lender shall have all
rights and remedies provided by law and any rights and remedies contained in any
other Loan Documents. All such rights and remedies shall be cumulative.

         10.2     NO WAIVER. No delay on the part of Lender in exercising any
right, power or privilege under this Agreement or any Loan Document shall
operate as a waiver, nor shall any single or partial exercise of any right,
power or privilege under this Agreement or otherwise, preclude other or further
exercise of the right, power or privilege or the exercise of any other right,
power or privilege.


                               11. CROSS-GUARANTY

         11.1     CROSS-GUARANTY. Each Borrower hereby acknowledges and agrees
that such Borrower is jointly and severally liable for, and hereby absolutely
and unconditionally guarantees to Lender and its successors and assigns, the
full and prompt payment (whether at stated maturity, by acceleration or
otherwise) and performance of, all Obligations owed or hereafter owing to Lender
by the other Borrowers. Each Borrower agrees that its guaranty obligation
hereunder is a guaranty of payment and performance and not of collection, and
that its obligations under this Section 11 shall be absolute and unconditional,
irrespective of, and unaffected by,

                  (a)      the genuineness, validity, regularity, enforceability
         or any future amendment of, or change in, this Agreement, any other
         Loan Document or any other agreement, document or instrument to which
         any Borrower is or may become a party;

                  (b)      the absence of any action to enforce this Agreement
         (including this Section 11) or any other Loan Document or the waiver or
         consent by Lender with respect to any of the provisions thereof;

                  (c)      the existence, value or condition of, or failure to
         perfect its lien or security interest against, any security for the
         Obligations or any action, or the absence of any action, by Lender in
         respect thereof (including, without limitation, the release of any such
         security); or

                  (d)      any other action or circumstances which might
         otherwise constitute a legal or equitable discharge or defense of a
         surety or guarantor,

it being agreed by each Borrower that its obligations under this Section 11
shall not be discharged until the payment and performance, in full, of the
Obligations has occurred. Each Borrower shall be regarded, and shall be in the
same position, as principal debtor with respect to the Obligations guaranteed
hereunder. Each Borrower expressly waives all rights it may have now or in the
future under any statute, or at common law, or at law or in equity, or
otherwise, to compel Lender to proceed in respect of the Obligations guaranteed



                                       30
<PAGE>   31

hereunder against any other Borrower or any other party or against any security
for the payment and performance of the Obligations before proceeding against, or
as a condition to proceeding against, such Borrower. Each Borrower agrees that
any notice or directive given at any time to Lender which is inconsistent with
the waiver in the immediately preceding sentence shall be null and void and may
be ignored by Lender, and, in addition, may not be pleaded or introduced as
evidence in any litigation relating to this Agreement (including this Section
11) for the reason that such pleading or introduction would be at variance with
the written terms of this Agreement (including this Section 11), unless Lender
has specifically agreed otherwise in writing. It is agreed among each Borrower
and Lender that the foregoing waivers are of the essence of the transaction
contemplated by this Agreement and the other Loan Documents and that, but for
the provisions of this Section 11 and such waivers, Lender would decline to
enter into this Agreement.

         11.2 DEMAND BY LENDER. In addition to the terms of the guaranty set
forth in Section 11.1 hereof, and in no manner imposing any limitation on such
terms, it is expressly understood and agreed that, if the then outstanding
principal amount of the Obligations under this Agreement (together with all
accrued interest thereon) is declared to be immediately due and payable, then
each Borrower shall, without demand, pay to the holders of the Obligations the
entire outstanding Obligations due and owing to such holders. Payment by any
Borrower shall be made to Lender, to be credited and applied to the Obligations,
in immediately available Federal funds to an account designated by Lender or at
the address set forth herein for the giving of notice to Lender or at any other
address that may be specified in writing from time to time by Lender.

         11.3 ENFORCEMENT OF GUARANTY. Each Borrower agrees that in no event
shall Lender have any obligation (although it is entitled, at its option) to
proceed against any other Borrower or any other person or any real or personal
property pledged to secure the Obligations before seeking satisfaction from such
Borrower, and Lender may proceed, prior or subsequent to, or simultaneously
with, the enforcement of Lender's rights under this Section 11, to exercise any
right or remedy which it may have against any property, real or personal, as a
result of any lien or security interest it may have as security for all or any
portion of the Obligations.

         11.4 WAIVER. In addition to the waivers contained in Section 11.1
hereof, each Borrower waives, and agrees that it shall not at any time insist
upon, plead or in any manner whatever claim or take the benefit or advantage of,
any appraisal, valuation, stay, extension, marshaling of assets or redemption
laws, or exemption, whether now or at any time hereafter in force, which may
delay, prevent or otherwise affect the performance by such Borrower of the
Obligations guaranteed under, or the enforcement by Lender of, this Section 11.
Each Borrower hereby waives diligence, presentment and demand (whether for
non-payment or protest or of acceptance, maturity, extension of time, change in
nature or form of the Obligations, acceptance of further security, release of
further security, composition or agreement arrived at as to the amount of, or
the terms of, the Obligations, notice of adverse change in any other Borrower's
financial condition or any other fact which might materially increase the risk
to such Borrower) with respect to any of the Obligations guaranteed hereunder or
all other demands whatsoever and waives the benefit of all provisions of law
which are or might be in conflict with the terms of this Section 11. Each
Borrower represents, warrants and agrees that, as of the date hereof, its
obligations under this Section 11 are not subject to any offsets or defenses
against Lender or any other



                                       31
<PAGE>   32

Borrower of any kind. Each Borrower further agrees that its obligations under
this Section 11 shall not be subject to any counterclaims, offsets or defenses
against Lender or against any other Borrower of any kind which may arise in the
future.

         11.5 BENEFIT OF GUARANTY. Each Borrower agrees that the provisions of
this Section 11 are for the benefit of Lender and its successors, transferees,
endorsees and assigns, and nothing herein contained shall impair, as between any
other Borrower and Lender, the obligations of any such other Borrower under the
Loan Documents. In the event all or any part of the Obligations are transferred,
endorsed or assigned by Lender to any person or persons, any reference to
"Lender" herein shall be deemed to refer equally to such person or persons.

         11.6 REINSTATEMENT. The provisions of this Section 11 shall remain in
full force and effect and continue to be effective should any petition be filed
by or against any Borrower for liquidation or reorganization, should any
Borrower become insolvent or make an assignment for the benefit of creditors or
should a receiver or trustee be appointed for all or any significant part of any
Borrower's assets, and shall continue to be effective or be reinstated, as the
case may be, if at any time payment and performance of the Obligations, or any
part thereof, is, pursuant to applicable law, rescinded or reduced in amount, or
must otherwise be restored or returned by Lender, whether as a "voidable
preference", "fraudulent conveyance", or otherwise, all as though such payment
or performance had not been made. In the event that any payment, or any part
thereof, is rescinded, reduced, restored or returned, the Obligations shall be
reinstated and deemed reduced only by such amount paid and not so rescinded,
reduced, restored or returned.

         11.7 WAIVER OF SUBROGATION, ETC. Notwithstanding anything to the
contrary in this Agreement or in any other Loan Document, and except as set
forth in Section 11.11, each Borrower hereby:

                  (a) expressly and irrevocably waives, to the fullest extent
possible at all times prior to the expiration or termination of this Agreement,
on behalf of itself and its successors and assigns (including any surety) and
any other person, any and all rights at law or in equity to subrogation,
reimbursement, exoneration, contribution, indemnification, set off or any other
rights that could accrue to a surety against a principal, to a guarantor against
a principal, to a guarantor against a maker or obligor, to an accommodation
party against the party accommodated, to a holder or transferee against a maker,
or to the holder of any claim against any person, and which such Borrower may
have or hereafter acquire against any other Borrower or any person in connection
with or as a result of such Borrower's performance of this Section 11, or any
other documents to which such Borrower is a party or otherwise;

                  (b) expressly and irrevocably waives any "claim" (as such term
is defined in the United States Bankruptcy Code) of any kind against any other
Borrower, and further agrees that it shall not have or assert any such rights
against any person (including any surety), either directly or as an attempted
set off to any action commenced against such Borrower by Lender or any other
person;

                  (c) acknowledges and agrees (i) that this waiver is intended
to benefit Lender and shall not limit or otherwise effect such Borrower's
liability hereunder or the



                                       32
<PAGE>   33

enforceability of this Section 11, and (ii) that Lender and its respective
successors and assigns are intended third party beneficiaries of the waivers and
agreements set forth in this Section 11.7.

         11.8 ELECTION OF REMEDIES. If Lender, under applicable law, proceeds to
realize its benefits under any of the Loan Documents giving Lender a lien or
security interest upon any Collateral, (whether owned by any Borrower or by any
other person), either by judicial foreclosure or by non-judicial sale or
enforcement permitted herein, Lender may, at its sole option, determine which of
its remedies or rights it may pursue without affecting any of its rights and
remedies under this Section 11. If, in the exercise of any of its rights and
remedies, Lender shall forfeit any of its rights or remedies, including its
right to enter a deficiency judgment against any Borrower or any other person,
whether because of any applicable laws pertaining to "election of remedies" or
the like, each Borrower hereby consents to such action by Lender and waives any
claim based upon such action, even if such action by Lender shall result in a
full or partial loss of any rights of subrogation which each Borrower might
otherwise have had but for such action by Lender. Any election of remedies which
results in the denial or impairment of the right of Lender to seek a deficiency
judgment against any Borrower shall not impair any other Borrower's obligation
to pay the full amount of the Obligations. In the event Lender shall bid at any
foreclosure or trustee's sale or at any private sale permitted by law or the
Loan Documents, Lender may bid all or less than the amount of the Obligations
and the amount of such bid need not be paid by Lender but shall be credited
against the Obligations. So long as the sale is commercially reasonable, and
regardless of whether Lender or a third party is the successful bidder, the
amount of the successful bid at any such sale, shall be conclusively deemed to
be the fair market value of the Collateral and the difference between such bid
amount and the remaining balance of the Obligations shall be conclusively deemed
to be the amount of the Obligations guaranteed under this Section 11,
notwithstanding that any present or future law or court decision or ruling may
have the effect of reducing the amount of any deficiency claim to which Lender
might otherwise be entitled but for such bidding at any such sale.

         11.9 CONTINUING GUARANTY. Each Borrower agrees that the guaranty set
forth in this Section 11 is a continuing guaranty and shall remain in full force
and effect until the payment and performance in full of the Obligations.

         11.10 LIMITATION. Notwithstanding any provision herein contained to the
contrary, each Borrower's liability under this Section 11 shall be limited to an
amount not to exceed as of any date of determination the greater of:

                  (i) the net amount of all Loans advanced to the other
Borrowers under this Agreement and then re-loaned or otherwise transferred to
such Borrower; or

                  (ii) the amount which could be claimed by the Lender from such
Borrower under this Section 11 without rendering such claim voidable or
avoidable under Section 548 of Chapter 11 of the Bankruptcy Code or under any
applicable state Uniform Fraudulent Transfer Act, Uniform Fraudulent Conveyance
Act or similar statute or common law after taking into account, among other
things, such Borrower's right of contribution and indemnification from the other
Borrowers under Section 11.2 hereof.

         11.11    CONTRIBUTION WITH RESPECT TO GUARANTY OBLIGATIONS.

                  (a) To the extent that any Borrower shall make a payment under
this Section 11 of all or any of the Obligations (other than Loans made to that
Borrower for which it is primarily liable) (a "Guarantor Payment") which, taking
into account all other Guarantor Payments then previously or concurrently made
by the other Borrowers, exceeds the amount which such Borrower would otherwise
have paid if each Borrower had paid the aggregate Obligations satisfied by such
Guarantor Payment in the same proportion that such Borrower's "Allocable Amount"
(as defined below) (as determined immediately prior to such Guarantor Payment)
bore to the aggregate Allocable Amounts of each of the Borrowers as determined
immediately prior to the making of such Guarantor Payment, then such Borrower
shall be entitled to receive contribution and indemnification payments from, and
be reimbursed by, the other Borrowers for the amount of such excess, pro rata
based upon their respective Allocable Amounts in effect immediately prior to
such Guarantor Payment.

                  (b) As of any date of determination, the "Allocable Amount" of
any Borrower shall be equal to the maximum amount of the claim which could then
be recovered from such Borrower under this Section 11 without rendering such
claim voidable or avoidable under Section 548 of Chapter 11 of the Bankruptcy
Code or under any applicable state Uniform Fraudulent Transfer Act, Uniform
Fraudulent Conveyance Act or similar statute or common law.

                  (c) This Section 11.11 is intended only to define the relative
rights of Borrowers and nothing set forth in this Section 11.11 is intended to
or shall impair the obligations of Borrowers, jointly and severally, to pay any
amounts as and when the same shall become due and payable in accordance with the
terms of this Agreement. Nothing contained in this Section 11.11 shall limit the
liability of any Borrower to pay any Loans made to that Borrower and accrued
interest, and Expenses with respect thereto for which such Borrower shall be
primarily liable.

                  (d) The parties hereto acknowledge that the rights of
contribution and indemnification hereunder shall constitute assets of the
Borrower to which such contribution and indemnification is owing.

                  (e) The rights of the parties under this Section 11.11 shall
be exercisable from and after the expiration or termination of this Agreement.

         11.12 LIABILITY CUMULATIVE. The liability of Borrowers under this
Section 11 is in addition to and shall be cumulative with all liabilities of
each Borrower to Lender under this Agreement and the other Loan Documents to
which such Borrower is a party or in respect of any Obligations or obligation of
the other Borrowers, without any limitation as to amount, unless the instrument
or agreement evidencing or creating such other liability specifically provides
to the contrary.

                                12. GENERAL TERMS

         12.1     EXPENSES, FEES AND COSTS; INDEMNIFICATION.

                  (a) Each Borrower is responsible for the payment of all
Expenses. Each Borrower also agrees to indemnify Lender for any and all Claims
that may be imposed on, incurred by or asserted against Lender in connection
with this Agreement or any Loan Document or transaction contemplated hereby or
thereby or the business relationship between Lender, on the one hand, and any
one or more of the Borrowers or the Validity Certificators, on the other hand,
except for willful misconduct or gross negligence.

                  (b) Each Borrower's obligation to pay the Expenses and all of
the reimbursement obligations and indemnification obligations provided for in
this Section 12.1 are part of the Obligations, are secured by all of the
Collateral, and survive the repayment of the Obligations.

         12.2 SUCCESSORS. The provisions of this Agreement shall inure to the
benefit of and be binding upon any successor to any of the parties to this
Agreement and shall extend and be available to any holder of any of the Notes;
provided, however, that persons or entities which succeed to the rights of any
Borrower under this Agreement shall not be entitled to enforce any rights or
remedies of any Borrower under or by reason of the terms of this Agreement, or
any other agreement referred to or incorporated by reference into this
Agreement, unless they shall have obtained Lender's prior written consent to
succeed to such rights, which consent will not be unreasonably withheld or
delayed.

         12.3 ASSIGNMENTS AND PARTICIPATIONS. Each Borrower consents to Lender's
sale of participations in the Loans and to Lender's assignment of the Loan
Documents or any interest therein to any third party. Provided Lender gives
Borrowers prompt notice of such sale, including the percentage interest of each
participant, each Borrower also acknowledges and agrees that any participation
will give rise to a direct obligation of each Borrower to the participant and
the participant shall, for purposes of Sections 12.1, be considered to be
"Lender."

         12.4 WAIVERS BY BORROWERS. Except as otherwise provide for in this
Agreement or by applicable law, each Borrower waives: (i) presentment, demand
and protest and notice of presentment, dishonor, notice of intent to accelerate,
notice of acceleration, protest, default, nonpayment, maturity, release,
compromise, settlement, extension or renewal of any or all commercial paper,
accounts, contract rights, documents, instruments, chattel paper and guaranties
at any time held by Lender on which Borrower may in any way be liable, and
hereby ratifies and confirms whatever Lender may do in this regard, (ii) all
rights to notice and a hearing prior to Lender's taking possession or control
of, or to Lender's replevy, attachment or levy upon, the Collateral or any bond
or security which might be required by any court prior to allowing Lender to
exercise any of its remedies, and (iii) the benefit of all valuation, appraisal
and exemption laws.

         12.5 ANTI-WAIVER; AMENDMENTS; AND CUMULATIVE REMEDIES PROVISIONS. No
failure or delay on the part of Lender or the holder of any Note in the exercise
of any power or right, and no course of dealing between any Borrower and Lender
or the holder of any Note, shall operate as a waiver of such power or right, nor
shall any single or partial



                                       35
<PAGE>   36

exercise of any power or right preclude other or further exercise thereof or the
exercise of any other power or right. The remedies provided for herein are
cumulative and not exclusive of any remedies which may be available to Lender at
law or in equity. No notice to or demand on any Borrower not required hereunder
or under any Note or other agreement shall in any event entitle any Borrower to
any other or further notice or demand in similar or other circumstances or
constitute a waiver of the right of Lender or the holder of any Note to any
other or further action in any circumstances without notice or demand. Any
waiver of any provision of this Agreement, any Note or other agreement, and any
consent to any departure by any Borrower from the terms of any provision of this
Agreement, any Note or other agreement, shall be effective only in the specific
instance and for the specific purpose for which given. Neither this Agreement
nor any Note or other agreement nor any terms hereof or thereof may be changed,
waived, discharged or terminated unless such change, waiver, discharge or
termination is in writing signed by the applicable Borrower and Lender.

         12.6 CONTROLLING LAW. This Agreement, the Notes and any other
agreements between the parties shall be governed by and construed in accordance
with the internal laws of the State of Michigan applicable to contracts made and
performed within Michigan without regard to conflict of laws provisions.

         12.7 COUNTERPARTS. This Agreement may be signed in any number of
counterparts with the same effect as if all signatures were upon the same
instrument.

         12.8 NOTICES. All communications or notices that are required or may be
given under this Agreement shall be deemed to have been served when personally
delivered or actually received if sent via telecopier or on the date when
deposited for delivery with a nationally recognized overnight courier, and
addressed as follows (unless and until Lender or any Borrower advises the other
party, in writing, of a change in such address): (a) if to any Borrower, with
the name and address of such Borrower shown at the beginning of this Agreement
with a copy to John W. Hilbert, Esq. Shumaker, Loop & Kendrick, LLP, 1000
Jackson St., Toledo, Ohio, 43624; and (b) if to Lender, addressed to Lender, to
the attention of Senior Credit Manager, at the address set forth at the
beginning of this Agreement with a copy to Donald F. Baty, Jr., Honigman Miller
Schwartz & Cohn, 2290 First National Building, 660 Woodward Avenue, Detroit,
Michigan 48226-3583.

         12.9 LOAN AGREEMENT CONTROLS. Anything contained in any other agreement
referred to in this Agreement or in any other agreement now existing between
Lender and the Borrowers to the contrary notwithstanding, in the event of any
express conflict between the terms and provisions of such other agreement and
those contained in this Agreement, the terms of this Agreement shall govern and
control.

         12.10 PARTIAL INVALIDITY. The unenforceability for any reason of any
provision of this Agreement shall not impair or limit the operation or validity
of any other provisions of this Agreement or any other existing or future
agreements between Lender and any Borrower.

         12.11 LEGAL RATE ADJUSTMENT. This Agreement, the Notes and all other
Loan Documents between each Borrower and Lender are expressly limited so that in
no event whatsoever shall the amount of interest paid or agreed to be paid to
Lender exceed the highest rate of interest permissible under applicable law. If,
from any circumstances,



                                       36
<PAGE>   37

fulfillment of any provision of this Agreement or the Notes at the time
performance of such provisions shall be due, shall involve exceeding the
interest limitation validly prescribed by law which a court of competent
jurisdiction may deem applicable to this Agreement and any Loans under this
Agreement, then the obligation to be fulfilled shall be reduced to an amount
computed at the highest rate of interest permissible under applicable law, and
if, for any reason whatsoever, Lender shall ever receive as interest an amount
which would be deemed unlawful under applicable law, such interest shall be
automatically applied to the payment of the principal of the Notes, as the case
may be (whether or not then due and payable), and not to the payment of
interest, or shall be refunded to the involved Borrower, if such principal has
been paid in full.

         12.12 SETOFF. In addition to any rights and remedies of Lender provided
by law, Lender has the right, without prior written notice to any Borrower, any
such required notice being expressly waived by each Borrower to the extent
permitted by applicable law, upon the occurrence of any Event of Default and so
long as such Event of Default is continuing, to set off and apply against any
Obligations, whether matured or unmatured, of each Borrower to Lender, any
amount owing by Lender to any Borrower, at or at any time after the happening of
any of the above mentioned events, and such right of setoff may be exercised by
Lender against any Borrower or against any assignee for the benefit of
creditors, receiver, or execution, judgment or attachment creditor of any
Borrower, or against anyone else claiming through or against any Borrower of
such assignee for the benefit of creditors, receiver, or execution, judgment or
attachment creditor, notwithstanding the fact that such right of setoff has not
been exercised by Lender prior to the making, filing or issuance or service upon
Lender of, or of notice of, assignment for the benefit of creditors, appointment
or application for the appointment of a receiver, or issuance of execution,
subpoena or order or warrant.

         12.13 NO MARSHALLING. Each Borrower, on its own behalf and on behalf of
its successors and assigns hereby expressly waives all rights, if any, to
require a marshalling of assets by Lender or to require that Lender first resort
to some or any portion of the Collateral before foreclosing upon, selling or
otherwise realizing on any other portion thereof.

         12.14 REINSTATEMENT OF OBLIGATIONS AND SECURITY. To the extent that any
Borrower makes a payment to Lender or Lender receives any payment(s) or proceeds
of Accounts or other Collateral for any Borrower's benefit, which payment(s) or
proceeds or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside and/or required to be repaid to a trustee,
receiver or any other party under any bankruptcy law, state or federal law,
common law or equitable doctrine, then, to the extent of such payment(s) or
proceeds received, any Borrower's obligations or part thereof intended to be
satisfied thereby shall be reinstated and continue in full force and effect, and
all collateral security therefor shall remain in full force and effect (or be
reinstated), as if such payment(s) or proceeds had not been received by Lender,
and an appropriate adjustment to Borrower's loan balance may be recorded, until
payment shall have been made to Lender, which payment shall be due on demand.

         12.15 SURVIVAL; RELIANCE. All agreements, representations and
warranties made in this Agreement (and all agreements referred to or
incorporated herein) shall survive the execution of this Agreement (and all
documents and agreements referred to or incorporated



                                       37
<PAGE>   38

herein) and the making of the Loans and the execution and delivery of the Notes.
Notwithstanding anything in this Agreement (or any documents or agreements
referred to or incorporated herein) to the contrary, no investigation or inquiry
by any party with respect to any matter which is the subject of any
representation, warranty, covenant or other agreement set forth herein or
therein is intended, nor shall it be interpreted, to limit, diminish or
otherwise affect the full scope and effect of any such representation, warranty,
covenant or other agreement. All terms, covenants, agreements, representations
and warranties of any Borrower made herein (or in any documents or agreements
referred to or incorporated herein), or in any certificate or other document
delivered pursuant hereto shall be deemed to be material and to have been relied
upon by Lender, notwithstanding any investigation heretofore or hereafter made
by Lender or its agents.

         12.16 INTERPRETATION. This Agreement (and all agreements referred to or
incorporated into this Agreement) are being entered into among competent
persons, who are experienced in business and represented by counsel, and has
been reviewed by the parties and their counsel. Therefore, any ambiguous
language in this Agreement (and all agreements referred to or incorporated
herein) will not necessarily be construed against any particular party as the
drafter of such language.

         12.17 INDEPENDENCE OF COVENANTS. All covenants hereunder are to be
given independent effect so that if a particular action or condition is not
permitted by any such covenant, the fact that it would be permitted by an
exception to, or would be otherwise within the limitations of, another covenant
shall not avoid the occurrence of a default or an Event of Default if such
action is taken or such condition exists.

         12.18 COMMUNICATION WITH ACCOUNTANTS. Each Borrower authorizes Lender
to communicate directly with its independent certified public accountants
including PriceWaterhouse Coopers and authorizes all such accountants to make
available to Lender all financial statements and other supporting financial
documents and schedules with respect to the business, financial condition and
other affairs of any Borrower. Such accountants are hereby instructed to make
available to Lender such information and records as Lender may reasonably
request and to otherwise comply with the provisions of this Section 12.18;
Borrowers shall have no liability if such accountants fail to make the requested
information available to Lender, but in all respects Borrowers shall not be
excused from compliance with other applicable provisions of this Agreement.
After the closing date, if any Borrower engages the services of accountants
other than PriceWaterhouse Coopers, each Borrower shall deliver a letter
addressed to and acknowledged by such accountants containing the same terms and
provisions as described above.

         12.19 COMMUNICATION WITH CUSTOMERS. During the continuance of any Event
of Default (or prior thereto with Borrower's prior consent, which will not be
unreasonably withheld), each Borrower authorizes Lender to communicate directly
with its customers regarding Borrower and Borrower's business relationship and
authorizes Lender to obtain, and the customers to provide, information and
documentation regarding Borrower's performance of its contracts, purchase orders
and other obligations to such customers.
