AMOUNT AND Terms OF CREDIT

AMOUNT AND NATURE OF CREDIT. Subject to the terms and conditions of this
Agreement, Bank shall make Loans to Borrowers, in such aggregate amount as
Borrowers shall request pursuant to the Revolving Credit Commitment and the Term
Loan Commitment; provided, however, that in no event shall the aggregate
principal amount of all Loans outstanding under this Agreement be in excess of
the Commitment.

The Loans may be made as Revolving Loans and as a Term Loan, as follows:

Revolving Credit.

      1. Subject to the terms and conditions of this Agreement, during the
Commitment Period, Bank shall make a Revolving Loan or Revolving Loans to
Borrowers in such amount or amounts as Borrowers may from time to time request,
but not exceeding in aggregate principal amount at any time outstanding
hereunder the Revolving Credit Commitment. Borrowers shall, subject to the terms
and conditions set forth herein, borrow Revolving Loans, maturing on the last
day of the Commitment Period, by means of any combination of LIBOR Loans and
Base Rate Loans, at its discretion as provided herein.

Borrowers shall pay interest on the unpaid principal amount of each LIBOR Loan
outstanding from time to time, from the date thereof until paid, at the Derived
LIBOR Rate, fixed in advance for each Interest Period, as herein provided for
each such Interest Period. Interest on such LIBOR Loans shall be payable on each
Interest Adjustment Date with respect to an Interest Period.

Borrowers shall pay interest on the unpaid principal amount of Base Rate Loans
outstanding from time to time from the date thereof until paid at the Derived
Prime Rate from time to time in effect. Interest on such Base Rate Loans shall
be payable, commencing August 31, 2004, and on the last day of each succeeding
month thereafter and at the maturity thereof.

At the request of Borrowers, Bank shall convert Base Rate Loans to LIBOR Loans
at any time and Bank shall convert LIBOR Loans to Base Rate Loans on any
Interest Adjustment Date. The obligation of Borrowers to repay the Base Rate
Loans and LIBOR Loans made by Bank and to pay interest thereon shall be
evidenced by a Revolving Credit Note of Borrowers in the form of Exhibit A
hereto, dated the Closing Date. Subject to the provisions of this Agreement,
Borrowers shall be entitled under this Section 2.1A to borrow funds, repay the
same in whole or in part and re-borrow hereunder at any time and from time to
time during the Commitment Period.

2. Letters of Credit.

Subject to the terms and conditions hereof, Bank shall issue or cause the
issuance of Letters of Credit ("Letters of Credit") on behalf of Borrowers;
provided, however, that Bank will not be required to issue any Letters of Credit
to the extent that the face amount of such Letters of Credit outstanding at any
time would exceed $250,000 or would cause the sum of (i) the outstanding
Revolving Loans plus (ii) outstanding Letters of Credit to exceed the Revolving
Credit Commitment. All disbursements or payments made by Bank related to Letters
of Credit shall be deemed to be Revolving Loans.

      Borrowers may request by written notice not later than 10:00 a.m. Eastern
Time five (5) Business Days prior to the requested date of issuance that Bank to
issue a Letter of Credit by

<PAGE>

certificates, documents and other papers and information as Bank may reasonably
request. Borrowers also have the right to give instructions and make agreements
with respect to any application, any applicable letter of credit and security
agreement, any applicable letter of credit reimbursement agreement and/or any
other applicable agreement, any letter of credit and the disposition of
documents, disposition of any unutilized funds, and to agree with Bank upon any
amendment, extension or renewal of any Letter of Credit. Each Letter of Credit
shall have an expiry date not later than six (6) months after such Letter of
Credit's date of issuance and in no event later than the last day of the
Commitment Period.

      In connection with the issuance of any Letter of Credit, Borrowers shall,
jointly and severally, indemnify, save and hold Bank harmless from any loss,
cost, expense or liability, including, without limitation, payments made by Bank
and expenses and reasonable attorneys' fees incurred by Bank arising out of, or
in connection with, any Letter of Credit to be issued or created for any
Borrower other than such losses, costs, expenses or liabilities which arise from
Bank's willful misconduct. Borrowers shall be bound by Bank's regulations and
good faith interpretations of any Letter of Credit issued for any Borrower's
account, although this interpretation may be different from its own; and neither
Bank nor any of its correspondents shall be liable for any error, negligence, or
mistakes, whether of omission or commission, in following any Borrower's
instructions or those contained in any Letter of Credit or of any modifications,
amendments or supplements thereto or in issuing or paying any Letter of Credit,
except for Bank's or such correspondents' willful misconduct.

      In connection with all Letters of Credit issued by Bank under this
Agreement, each Borrower hereby appoints Bank, or its designee, as its attorney,
with full power and authority upon the occurrence and during the continuance of
an Event of Default (i) to sign and/or endorse a Borrower's name upon any
warehouse or other receipts, letter of credit applications and acceptances; (ii)
to sign a Borrower's name on bills of lading; (iii) to clear Inventory through
the United States of America Customs Department ("Customs") in the name of a
Borrower or Bank or Bank's designee, and to sign and deliver to Customs
officials powers of attorney in the name of Borrower for such purpose; and (iv)

any order, sale or transaction, obtain the necessary documents in connection
therewith, and collect the proceeds thereof. Neither Bank nor its attorneys will
be liable for any acts or omissions nor for any error of judgment or mistakes of
fact or law, except for Bank's or its attorney's willful misconduct. This power,
being coupled with an interest, is irrevocable as long as any Letters of Credit
remain outstanding.

Term Loan.

Subject to the terms and conditions of this Agreement, Bank shall make a five
(5) year Term Loan to Borrowers in the amount of the Term Loan Commitment. To
evidence the Term Loan, Borrowers shall execute and deliver to Bank a Term Note
in the form of Exhibit B hereto. The Term Loan shall be payable in fifty nine
(59) consecutive monthly installments of Sixteen Thousand Six Hundred Sixty Six
and 67/100 Dollars ($16,666.67), commencing August 31, 2004 and continuing on
the last day of each succeeding month thereafter, through June 30, 2009, with
the balance thereof payable in full on July 31, 2009, in the case of each
installment together with then accrued and unpaid interest on the Term Loan.

If requested by Borrowers as provided herein, the Term Loan shall be a LIBOR
Loan or a Base Rate Loan or a combination thereof, at Borrowers' discretion,
exercised as provided herein.

If the Term Loan is a LIBOR Loan, Borrowers shall pay interest on the unpaid
principal amount of each LIBOR Loan outstanding from time to time from the date
thereof until paid, fixed in advance for each Interest Period, as herein
provided for each such Interest Period. Interest on

<PAGE>

such LIBOR Loans shall be at the Derived LIBOR Rate, payable on each Interest
Adjustment Date with respect to an Interest Period.

If the Term Loan is a Base Rate Loan, Borrowers shall pay interest on the unpaid
principal amount thereof outstanding from time to time from the date thereof
until paid, commencing August 31, 2004, and continuing on the last day of each
succeeding month thereafter and at the maturity thereof, at the Derived Prime
Rate from time to time in effect.

At the request of the Borrowers, Bank shall convert Base Rate Loans to LIBOR
Loans at any time and Bank shall convert LIBOR Loans to Base Rate on any
Interest Adjustment Date.

CONDITIONS TO LOANS. The obligation of Bank to make any Loan, convert a Base
Rate Loan to a LIBOR Loan, convert a LIBOR Loan to a Base Rate Loan or continue
a LIBOR Loan hereunder is conditioned, in the case of each borrowing, conversion
or continuation, upon:

      all conditions precedent as listed in Article IV hereof shall have been
satisfied; with respect to Base Rate Loans, receipt by Bank of a Notice of Loan,
such notice to be received by 11:00 A.M. (Cleveland, Ohio time) on the proposed
date of borrowing or conversion, and, with respect to LIBOR Loans, three (3)
Business Days prior to the proposed date of borrowing, conversion or
continuation; [intentionally omitted];

The fact that no Unmatured Event of Default or Event of Default shall then exist
or immediately after the making of the Loan would exist; the fact that each of
the representations and warranties contained in Article VII hereof shall be true
and correct in all material respects (except for those that are qualified by
reference to materiality or Material Adverse Effect, which shall be true and
correct) with the same force and effect as if made on and as of the date of the
making of such Loan except to the extent that any thereof expressly relate to an
earlier date; and

(f) with respect to Revolving Loans, Borrowers' delivery of the Borrowing Base
Certificate (i) from the Closing Date until February 28, 2005, on a weekly basis
on the day requested by Bank and (ii) thereafter monthly within 7 days of the
end of the month.

Each request by a Borrower for the making of a Loan, conversion of a Base Rate
Loan to a LIBOR Loan, conversion of a LIBOR Loan or a Base Rate Loan or
continuation of a LIBOR Loan hereunder shall be deemed to be a representation
and warranty by Borrowers as of the date of such request as to the facts
specified in (d) and (f) above.

Each request for a LIBOR Loan shall be irrevocable and binding on Borrowers and
Borrowers shall, jointly and severally, indemnify Bank against any loss or
expense incurred by Bank as a result of any failure by a Borrower to consummate
such transaction including, without limitation, any loss (including loss of
anticipated profits) or expense incurred by reason of liquidation or
reemployment of deposits or other funds acquired by Bank to fund such LIBOR Loan
other than losses or expenses arising from Bank's willful misconduct. A
certificate as to the amount of such loss or expense submitted by Bank to any
Borrower shall be conclusive and binding for all purposes, absent manifest
error.

PAYMENT ON NOTES, ETC. All payments of principal, interest and fees and other
amounts payable hereunder shall be made to Bank in immediately available funds.
Bank shall record (a) any principal, interest or other payment, and (b) the
principal amount of the Base Rate Loans and LIBOR Loans and all prepayments
thereof and the applicable dates with respect thereto, by such method as Bank
may generally employ; provided, however, that failure to make any such entry
shall in no way detract from Borrowers' obligations under each Note. The
aggregate unpaid amount of the Base Rate Loans and LIBOR Loans set forth on the
records of Bank shall be rebuttably presumptive evidence of the principal and
interest owing and unpaid on each Note. Whenever any payment to be made
hereunder, including, without limitation, any payment to be made on any Note,
shall be stated to be due on a day that is not a Business Day, such payment
shall be made on the next succeeding Business Day and such extension of time
shall in each case

<PAGE>

be included in the computation of the interest payable on each Note; provided,
however, that, with respect to any LIBOR Loan, if the next succeeding Business
Day falls in the succeeding calendar month, such payment shall be made on the
preceding Business Day and the relevant interest period shall be adjusted
accordingly.

PREPAYMENT. Borrowers shall have the right at any time or from time to time to
prepay all or any part of the principal amount of the Notes then outstanding as
designated by Borrowers, plus interest accrued on the amount so prepaid to the
date of such prepayment. Borrowers shall give Bank notice of prepayment of any
Base Rate Loan by not later than 11:00 A.M. (Cleveland, Ohio time) on the
Business Day such prepayment is to be made and written notice of the prepayment
of any LIBOR Loan later than 1:00 P.M. (Cleveland, Ohio time) three (3) Business
Days before the Business Day on which such payment is to be made. Prepayments of
any Loan shall be without any premium or penalty.

Each prepayment of the Term Loan shall be applied to the principal installments
thereof in the inverse order of their respective maturities.

In any case of prepayment of a LIBOR Loan, each Borrower agrees that if Adjusted
LIBOR as determined as of 11:00 A.M. (London time), three (3) Business Days
prior to the date of prepayment of such LIBOR Loan (hereinafter, "Prepayment
LIBOR") shall be lower than the last Adjusted LIBOR previously determined for
such LIBOR Loan with respect to which prepayment is intended to be made
(hereinafter, "Last LIBOR"), then Borrowers shall, upon written notice by Bank,
promptly pay to Bank in immediately available funds, a prepayment fee equal to
the product of (a) a rate (the "Prepayment Rate") that shall be equal to the
difference between the Last LIBOR and the Prepayment LIBOR, times (b) all or
such part of the principal amounts of the Notes as relate to the LIBOR Loan to
be prepaid, times (c) the number of days in the period commencing with the date
on which such prepayment is to be made to that date that coincides with the last
day of the Interest Period previously established when the LIBOR Loan, that is
to be prepaid, was made. In addition, Borrowers shall immediately pay directly
to Bank, the amount claimed as additional costs or expenses (including, without
limitation, cost of telex, wires, or cables) incurred in connection with the
prepayment, upon Borrower's receipt of a written statement from Bank.

UNUSED FEE. Borrowers shall pay to bank a fee equal to fifty (50) basis points
per annum on the amount by which the Maximum Revolving Credit Amount exceeds the
average daily unpaid balance. Such fee shall be payable to Bank in arrears on
the last day of each Fiscal quarter with respect to the prior quarter, prorated
for partial periods. The first payment of this fee will be due September 30,
2004.

COMPUTATION OF INTEREST AND FEES; DEFAULT RATE. Interest on Loans, Related
Expenses and fees and charges hereunder shall be computed on the basis of a year
having three hundred sixty (360) days and calculated for the actual number of
days elapsed. Anything herein to the contrary notwithstanding, if an Event of
Default shall occur hereunder, the principal of each Note shall bear interest,
until paid, at the Default Rate. In no event shall the rate of interest
hereunder exceed the maximum rate allowable by law.

MANDATORY PREPAYMENT. If the sum of the aggregate principal amount of all
Revolving Loans outstanding at any time exceeds the Revolving Credit Commitment,
Borrower shall, as promptly as practicable, but in no event later than three (3)
Business Days, prepay an aggregate principal amount of the Revolving Loans
sufficient to bring the aggregate outstanding principal amount of all Revolving
Loans within the Revolving Credit Commitment.

OPTIONAL REDUCTION OF REVOLVING CREDIT COMMITMENT. Borrowers may, from time to
time, permanently reduce in whole or in part the Revolving Credit Commitment to
an amount not less than the aggregate amount of Revolving Loans then outstanding
plus the amount of any outstanding Letters of Credit by giving the Bank not
fewer than 3 Business Days' notice of such reduction. After each such reduction,
the unused fee payable pursuant to Section

<PAGE>

2.5 hereof shall be calculated using the Revolving Credit Commitment as so
reduced. Any partial reduction in the Revolving Commitment shall be permanent.

ELECTRONIC DEBIT. All payments of principal, interest and fees hereunder, unless
otherwise requested by Bank, shall be made by electronic debt from Borrowers'
designated account on the scheduled due date thereof (excluding the payment due
on the maturity date of the Term Loan).

ADDITIONAL PROVISIONS RELATING TO LIBOR LOANS; INCREASED CAPITAL; TAXES.

RESERVES OR DEPOSIT REQUIREMENTS, ETC. If, at any time, any law, treaty or
regulation (including, without limitation, Regulation D of the Board of
Governors of the Federal Reserve System) or the interpretation thereof by any
governmental authority charged with the administration thereof or any central
bank or other fiscal, monetary or other authority shall impose (whether or not
having the force of law), modify or deem applicable any reserve and/or special
deposit requirement (other than reserves included in the Reserve Percentage, the
effect of which is reflected in the interest rate(s) of the LIBOR Loan(s) in
question) against assets held by, or deposits in or for the amount of any LIBOR
Loan by, Bank, and the result of the foregoing is to increase the cost (whether
by incurring a cost or adding to a cost) to Bank of making or maintaining
hereunder such LIBOR Loan or to reduce the amount of principal or interest
received by Bank with respect to such LIBOR Loan, then, upon demand by Bank,
Borrowers shall pay to Bank from time to time on Interest Adjustment Dates with
respect to such LIBOR Loan, as additional consideration hereunder, additional
amounts sufficient to fully compensate and indemnify Bank for such increased
cost or reduced amount, assuming (which assumption Bank need not corroborate)
such additional cost or reduced amount was allocable to such LIBOR Loan. A
certificate as to the increased cost or reduced amount as a result of any event
mentioned in this Section 3.1, setting forth the calculations therefor, shall be
promptly submitted by Bank to Borrowers and shall, in the absence of manifest
error, be conclusive and binding as to the amount thereof. Notwithstanding any
other provision of this Agreement, after any such demand for compensation by
Bank, Borrowers, upon at least three (3) Business Days' prior written notice to
Bank, may prepay any affected LIBOR Loan in full or convert such LIBOR Loan to a
Base Rate Loan regardless of the Interest Period thereof. Bank shall notify
Borrowers as promptly as practicable of the existence of any event that will
likely require the payment by Borrowers of any such additional amount under this
Section.

TAX LAW, ETC. In the event that by reason of any law, regulation or requirement
or in the interpretation thereof by an official authority, or the imposition of
any requirement of any central bank whether or not having the force of law, Bank
shall, with respect to this Agreement or any transaction under this Agreement,
be subjected to any tax, levy, impost, charge, fee, duty, deduction or
withholding of any kind whatsoever (other than any tax imposed upon the total
net income of Bank) and if any such measures or any other similar measure shall
result in an increase in the cost to Bank of making or maintaining any LIBOR
Loan or in a reduction in the amount of principal, interest or commitment fee
receivable by Bank in respect thereof, then Bank shall promptly notify Borrowers
stating in writing the reasons therefor. Borrowers shall thereafter pay to Bank,
upon demand from time to time on Interest Adjustment Dates with respect to such
LIBOR Loan, as additional consideration hereunder, such additional amounts as
shall fully compensate Bank for such increased cost or reduced amount. A
certificate as to any such increased cost or reduced amount, setting forth the
calculations therefor, shall be submitted by Bank to Borrowers and shall, in the
absence of manifest error, be conclusive and binding as to the amount thereof.

If Bank receives such additional consideration from Borrowers pursuant to this
Section 3.2, Bank shall use reasonable efforts to obtain the benefits of any
refund, deduction or credit for any taxes or other amounts on account of which
such additional consideration has been paid and shall reimburse Borrowers to the
extent, but only to the extent, that Bank shall receive a refund of

<PAGE>

such taxes or other amounts together with any interest thereon or an effective
net reduction in taxes or other governmental charges (including any taxes
imposed on or measured by the total net income of Bank) of the United States or
any state or subdivision thereof by virtue of any such deduction or credit,
after first giving effect to all other deductions and credits otherwise
available to Bank. If, at the time any audit of Bank's income tax return is
completed, Bank determines, based on such audit, that it was not entitled to the
full amount of any refund reimbursed to Borrowers as aforesaid or that its net
income taxes are not reduced by a credit or deduction for the full amount of
taxes reimbursed to Borrowers as aforesaid, Borrowers, upon demand of Bank,
shall promptly pay to Bank the amount so refunded to which Bank was not so
entitled, or the amount by which the net income taxes of Bank were not so
reduced, as the case may be. Notwithstanding any other provision of this
Agreement, after any such demand for compensation by Bank, Borrowers, upon at
least three (3) Business Days' prior written notice to Bank, may prepay any
affected LIBOR Loan in full or convert such LIBOR Loan to a Base Rate Loan
regardless of the Interest Period of any thereof.

<PAGE>

EURODOLLAR DEPOSITS UNAVAILABLE OR INTEREST RATE UNASCERTAINABLE. In respect of
any LIBOR Loan, in the event that Bank shall have determined that dollar
deposits of the relevant amount for the relevant Interest Period for such LIBOR
Loan is not available to the Reference Bank in the applicable eurodollar market
or that, by reason of circumstances affecting such market, adequate and
reasonable means do not exist for ascertaining the LIBOR Rate applicable to such
Interest Period, as the case may be, Bank shall promptly give notice of such
determination to Borrowers and (a) any notice of a new LIBOR Loan (or conversion
of an existing Loan to a LIBOR Loan) previously given by Borrowers and not yet
borrowed (or converted, as the case may be) shall be deemed a notice to make a
Base Rate Loan, and (b) Borrowers shall be obligated either to prepay, or to
convert to a Base Rate Loan, any outstanding LIBOR Loan on the last day of the
then current Interest Period with respect thereto.

INDEMNITY. Without prejudice to any other provisions of this Article III, each
Borrower hereby agrees, jointly and severally, to indemnify Bank against any
loss or expense that Bank may sustain or incur as a consequence of any default
by a Borrower in payment when due of any amount hereunder in respect of any
LIBOR Loan, including, but not limited to, any loss of profit, premium or
penalty incurred by Bank in respect of funds borrowed by it for the purpose of
making or maintaining such LIBOR Loan, as determined by Bank in the exercise of
its sole but reasonable discretion. A certificate as to any such loss or expense
shall be promptly submitted by Bank to Borrowers and shall, in the absence of
manifest error, be conclusive and binding as to the amount thereof.

CHANGES IN LAW RENDERING LIBOR LOANS UNLAWFUL. If at any time any new law,
treaty or regulation, or any change in any existing law, treaty or regulation,
or any interpretation thereof by any governmental or other regulatory authority
charged with the administration thereof, shall make it unlawful for Bank to fund
any LIBOR Loan that it is committed to make hereunder with moneys obtained in
the eurodollar market, the commitment of Bank to fund such LIBOR Loan shall,
upon the happening of such event forthwith be suspended for the duration of such
illegality, and Bank shall by written notice to Borrowers declares that its
commitment with respect to such LIBOR Loan has been so suspended and, if and
when such illegality ceases to exist, such suspension shall cease and Bank shall
similarly notify Borrowers. If any such change shall make it unlawful for Bank
to continue in effect the funding in the applicable eurodollar market of any
LIBOR Loan previously made by it hereunder, Bank shall, upon the happening of
such event, notify Borrowers thereof in writing stating the reasons therefor,
and Borrowers shall, on the earlier of (a) the last day of the then current
Interest Period or (b) if required by such law, regulation or interpretation, on
such date as shall be specified in such notice, either convert such LIBOR Loan
to a Base Rate Loan or prepay such LIBOR Loan in full.

FUNDING. Bank may, but shall not be required to, make LIBOR Loans hereunder with
funds obtained outside the United States.

CAPITAL ADEQUACY. If Bank shall have determined, after the Closing Date, that
the adoption of any applicable law, rule, regulation or guideline regarding
capital adequacy, or any change therein, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by Bank (or its lending office) with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on Bank's capital (or the capital of its holding company) as a
consequence of its obligations hereunder to a level below that which Bank (or
its holding company) could have achieved but for such adoption, change or
compliance (taking into consideration Bank's policies or the policies of its
holding company with respect to capital adequacy) by an amount reasonably deemed
by Bank to be material, then from time to time, within fifteen (15) days after
demand by Bank, Borrowers shall pay to Bank such additional amount or amounts as
will compensate Bank (or its holding

<PAGE>

company) for such reduction. Bank shall designate a different lending office if
such designation will avoid the need for, or reduce the amount of, such
compensation and will not, in the reasonable judgment of Bank, be otherwise
disadvantageous to Bank. A certificate of Bank claiming compensation under this
Section and setting forth the additional amount or amounts to be paid to it
hereunder shall be conclusive in the absence of manifest error. In determining
such amount, Bank may use any reasonable averaging and attribution methods.
Failure on the part of Bank to demand compensation for any reduction in return
on capital with respect to any period shall not constitute a waiver of Bank's
rights to demand compensation for any reduction in return on capital in such
period or in any other period. The protection of this Section shall be available
to Bank regardless of any possible contention of the invalidity or
inapplicability of the law, regulation or other condition that shall have been
imposed.

shall perform and observe, and shall cause each Subsidiary to perform and
observe, each of the following provisions:

INSURANCE. Borrowers shall at all times maintain insurance upon its Inventory,
Equipment and other personal and real property and against such risks as is
customary for entities in such Borrower's industry and of such Borrower's size
and in such form, written by such companies, in such amounts and for such
period, as may be reasonably acceptable to Bank, with provisions satisfactory to
Bank for payment of all losses thereunder to Bank and Borrowers as their
interests may appear (loss payable endorsement in favor of Bank), and, if
required by Bank, Borrowers shall deposit the policies with Bank. Any such
policies of insurance shall provide for no fewer than thirty (30) days prior
written notice of cancellation to Bank. Any sums received by Bank in payment of
insurance losses, returns, or unearned premiums under the policies may, at the
option of Bank, be applied upon any Debt whether or not the same is then due and
payable, or may be delivered to Borrowers for the purpose of replacing,
repairing, or restoring the insured property. Bank is hereby authorized to act
as attorney-in-fact for Borrowers in obtaining, adjusting, settling and
canceling such insurance and indorsing any drafts. In the event of failure to
provide

<PAGE>

such insurance as herein provided, Bank may, at its option, provide such
insurance and Borrowers shall pay to Bank, upon demand, the cost thereof. Should
Borrowers fail to pay such sum to Bank upon demand, interest shall accrue
thereon, from the date of demand until paid in full, at the Default Rate. Within
twenty (20) days of Bank's written request, Borrowers shall furnish to Bank such
information about any Company's insurance as Bank may from time to time
reasonably request, which information shall be prepared in form and detail
satisfactory to Bank and certified by a Financial Officer of each Borrower.

date when penalties would attach, all taxes, assessments and governmental
charges and levies (except only those so long as and to the extent that the same
shall be contested in good faith by appropriate and timely proceedings and for
which adequate reserves have been established in accordance with GAAP) for which
it may be or become liable or to which any or all of its properties may be or
become subject; (b) all of its wage obligations to its employees in compliance
with the Fair Labor Standards Act (29 U.S.C. 206-207) or any comparable
provisions; and (c) all of its other material obligations calling for the

shall be contested in good faith and for which adequate reserves have been
established in accordance with GAAP) before such payment becomes overdue.

FINANCIAL STATEMENTS. Borrowers shall furnish to Bank:

within thirty (30) days after the end of each month, balance sheets of each
Borrower as of the end of such quarter and statements of income (loss),
stockholders' equity and cash flow for the quarter and fiscal year to date

with GAAP, and in form and detail reasonably satisfactory to Bank and certified

public accountant satisfactory to Bank, which report shall include balance
sheets and statements of income (loss), stockholders' equity and cash-flow for
that period. In addition, Borrowers shall use reasonable efforts to cause the

Officer of the Company or Companies in question; and

(h) copies of all reports and other materials of each Borrower filed with the

and upon prior notice to such Company) permit Bank to examine that Company's
books and records and to make excerpts therefrom and transcripts thereof.

FRANCHISES. Each Company shall preserve and maintain at all times its existence,
rights and franchises except where the failure to preserve or maintain such
rights and franchises would not reasonably be expected to have a Material
Adverse Effect.

deficiency within the meaning of ERISA, or any material liability to the PBGC,
established thereunder in connection with any ERISA Plan. Borrowers shall
furnish to Bank (a) as soon as possible and in any event within thirty (30) days

any notice such Company, or any member of the Controlled Group may receive from
the PBGC or the Internal Revenue Service with respect to any ERISA Plan
administered by such Company; provided, that this latter clause shall not apply

Revenue Service. Borrowers shall promptly notify Bank of any material taxes
assessed, proposed to be assessed or which a Borrower has reason to believe may
be assessed against a Company by the Internal Revenue Service with respect to
any ERISA Plan. As soon as practicable, and in any event within twenty (20)
days, after any Company becomes aware that an ERISA Event has occurred, such
Company shall provide Bank with notice of such ERISA Event with a certificate by
a Financial Officer of such Company setting forth the details of the event and
the action such Company or another Controlled Group member proposes to take with
respect thereto. Borrowers shall, at the request of Bank, deliver or cause to be

employees of a Company or any Affiliate of a Company.

USE OF PROCEEDS. Borrowers' use of the proceeds of the Notes shall be solely for

deletions from the Equipment; and upon reasonable request of Bank, promptly take
such action and promptly make, execute, and deliver all such additional and
further items, deeds, assurances, and instruments as Bank reasonably may
require, including, without limitation, financing statements, so as to
completely vest in and ensure to Bank its rights hereunder and in or to the
Collateral.

If certificates of title or applications for title are issued or outstanding
with respect to any Borrower's Inventory or Equipment, such Borrower shall, upon
request of Bank, (i) execute and

deliver to Bank a short form security agreement, in form acceptable to Bank, and
(ii) deliver such certificate or application to Bank and cause the interest of
Bank to be properly noted thereon. Each Borrower hereby authorizes Bank or

Related Expenses (whether prior to, upon, or subsequent to any Unmatured Event
of Default or Event of Default), and Borrowers shall promptly repay, reimburse,
and indemnify Bank for any and all Related Expenses. If any Borrower fails to
keep and maintain the Equipment in good operating condition, following written
notice to Borrowers, Bank may (but shall not be required to) so maintain or
repair all or any part of the Equipment and the cost thereof shall be a Related
Expense. All Related Expenses are payable to Bank upon demand therefor; Bank
may, at its option, debit Related Expenses directly to the Revolving Credit Note

International to use reasonable efforts to enter into a sublease with respect to
the Vultron International Lease and any proceeds of any such sublease shall be

SECURITY INTEREST IN COLLATERAL. In consideration of and as security for the
full and complete payment of all of the Debt, each Borrower does hereby grant to
Bank a security interest in and an assignment of the Collateral.

COLLECTIONS AND RECEIPT OF PROCEEDS BY BORROWERS. Prior to exercise by Bank of
its rights under Article VIII of this Agreement, both (a) the lawful collection
and enforcement of all of each Borrower's Accounts, and (b) the lawful receipt
and retention by each Borrower of all Proceeds of all of such Borrower's
Accounts and Inventory shall be as the agent of Bank. At the Closing Date, a
Cash Collateral Account shall be opened by Borrowers at the main office of Bank

each Borrower's Accounts and Inventory shall be remitted daily by each Borrower
to Bank in the form in which they are received by Borrowers, either by mailing

for deposit in the Cash Collateral Account. In the event that such notice is
given to any Borrower from Bank, Borrowers shall not commingle such collections
or Proceeds with any of any Borrower's other funds or property, but shall hold
such collections and Proceeds separate and apart therefrom upon an express trust
for Bank. In such case, Bank may, in its sole discretion, at any time and from
time to time, apply all or any portion of the account balance in the Cash
Collateral Account as a credit against (i) the outstanding principal or interest
of any Note or Notes, or (ii) any other Debt. If any remittance shall be
dishonored, or if, upon final payment, any claim with respect thereto shall be
made against Bank on its warranties of collection, Bank may charge the amount of
such item against the Cash Collateral Account or any other Deposit Account
maintained by Borrowers with Bank, and, in any event, retain the same and each
Borrower's interest therein as additional security for the Debt. Bank may, in
its sole discretion, at any time and from time to time, release funds from the
Cash Collateral Account to Borrowers for use in Borrowers' business. The balance
in the Cash Collateral Account may be withdrawn by Borrowers upon termination of
this Agreement and payment in full of all of the Debt. Borrowers shall cause all
remittances representing collections and Proceeds of Collateral to be mailed to
a lock box in Cleveland, Ohio, so that

<PAGE>

Bank shall have access for the processing of such items in accordance with the
provisions, terms, and conditions of Bank's customary lock box agreement.

Bank, or Bank's designated agent, is hereby constituted and appointed Borrowers'
attorney-in-fact with authority and power to endorse any and all instruments,
documents, and chattel paper upon Borrowers' failure to do so. Such authority
and power, being coupled with an interest, shall be (A) irrevocable until all of
the Debt is paid, (B) exercisable by Bank at any time and without any request
upon Borrowers by Bank to so endorse, and (C) exercisable in Bank's name or any
Borrower's name. Each Borrower hereby waives presentment, demand, notice of
dishonor, protest, notice of protest, and any and all other similar notices with
respect thereto, regardless of the form of any endorsement thereof. Bank shall
not be bound or obligated to take any action to preserve any rights therein
against prior parties thereto.

COLLECTIONS AND RECEIPT OF PROCEEDS BY BANK. Each Borrower hereby constitutes
and appoints Bank, or Bank's designated agent, as such Borrower's
attorney-in-fact to exercise all or any of the following powers that, being
coupled with an interest, shall be irrevocable until the complete and full
payment of all of the Debt:

deposit, in Bank's name or any Borrower's name, any and all of each Borrower's
cash, instruments, chattel paper, documents, Proceeds of Accounts, Proceeds of
Inventory, collection of Accounts, and any other writings relating to any of the
Collateral; with prior written notice to Borrowers prior to the occurrence of an
Unmatured Event of Default or an Event of Default, and without such notice after
the occurrence and during the continuation of an Event of Default or an
Unmatured Event of Default, to transmit to Account Debtors, on any or all of
each Borrower's Accounts, notice of assignment to Bank thereof and Bank's
security interest therein and to request from such Account Debtors at any time,
in Bank's name or in each Borrower's name, information concerning such
Borrower's Accounts and the amounts owing thereon; with prior written notice to
Borrowers prior to the occurrence of an Unmatured Event of Default or an Event
of Default, and without such notice after the occurrence and during the
continuation of an Event of Default or an Unmatured Event of Default, to
transmit to purchasers of any or all of any Borrower's Inventory, notice of
Bank's security interest therein, and to request from such purchasers at any
time, in Bank's name or in any Borrower's name, information concerning each
Borrower's Inventory and the amounts owing thereon by such purchasers; with
prior written notice to Borrowers prior to the occurrence of an Unmatured Event
of Default or an Event of Default, and without such notice after the occurrence
and during the continuation of an Event of Default or an Unmatured Event of
Default, to notify and require Account Debtors on each Borrower's Accounts and
purchasers of each Borrower's Inventory to make payment of their indebtedness

collections in any form relating to the Collateral, including remittances that
may reflect deductions, and to deposit the same into a Borrower's Cash
Collateral Account or, at the option of Bank, to apply them as a payment against
any Note or Notes or any other Debt.

and until such Event of Default is waived in writing Bank) and Bank shall give
written notice to Borrower to the contrary, each Borrower may: (a) retain
possession of and use its Inventory and Equipment in any lawful manner not
inconsistent with this Agreement or with the terms, conditions, or provisions of
any policy of insurance thereon; (b) sell or lease its Inventory in the ordinary
course of business; provided, however, that a sale or lease in the ordinary

transfers in satisfaction of partial or total purchase money prepayments by a
buyer in the ordinary course of such Borrower's business; and (c) use and
consume any raw materials or supplies, the use and consumption of which are

months from the Closing Date, on or about the first anniversary of the Closing
Date and annually thereafter. The cost of which shall be borne by Borrowers.
Bank, upon prior notice, may conduct additional field audits (a) at its own
expense prior to an Event of Default that has not been waived or (b) at
Borrowers' cost after an Event of Default.

REPRESENTATIONS AND WARRANTIES

Each Borrower represents and warrants, jointly and severally, that the
statements set forth in this Article VII are true, correct and complete.

CORPORATE EXISTENCE; SUBSIDIARIES; FOREIGN QUALIFICATION. Each Company is a
corporation duly organized, validly existing, and in good standing under the
laws of its state of incorporation and is duly qualified and authorized to do
business and is in good standing as a foreign corporation in the jurisdictions
set forth opposite its name on Schedule 7.1 hereof, that are all of the states
or jurisdictions where the character of its property or its business activities
makes such qualification necessary, except where the failure to so qualify will
not cause or result in a Material Adverse Effect. Except for the other
Borrowers, as the case may be, none of the Borrowers has any Subsidiaries.

CORPORATE AUTHORITY. Each Borrower has the right and power and is duly
authorized and empowered to enter into, execute and deliver the Loan Documents
to which it is a party and to perform and observe the provisions of the Loan
Documents. The Loan Documents to which each Borrower is a party have been duly
authorized and approved by such Borrower's Board of Directors and are the valid
and binding obligations of such Borrower, enforceable against such Borrower in
accordance with their respective terms. The execution, delivery and performance
of the Loan Documents will not conflict with nor result in any breach in any of
the provisions of, or constitute a default under, or result in the creation of
any Lien (other than Liens permitted under Section 5.9 of this Agreement) upon
any assets or property of any Borrower under the provisions of such Borrower's
Governing Documents or any agreement.

COMPLIANCE WITH LAWS. Each Company:

      except as expressly set forth in the documents and reports identified on
Schedule 7.8 to this Agreement, holds permits, certificates, licenses, orders,
registrations, franchises, authorizations, and other approvals from federal,
state, local, and foreign governmental and regulatory bodies necessary for the
conduct of its business and is in substantial compliance with all applicable
laws relating thereto except where such non-compliance would not reasonably be
expected to have a Material Adverse Effect; except as expressly set forth in the
documents and reports identified on Schedule 7.8 to this Agreement, is in
substantial compliance with all federal, state, local, or foreign applicable
statutes, rules, regulations, and orders including, without limitation, those
relating to environmental protection, occupational safety and health, and equal
employment practices; and

(c) is not in violation of or in default under any material agreement to which
it is a party or by which its assets are subject or bound.

LITIGATION AND ADMINISTRATIVE PROCEEDINGS. Except as disclosed on Schedule 7.4
and Schedule 7.8, hereto, as to any of which would not reasonably be expected
have a Material Adverse Effect, there are (a) no lawsuits, actions,
investigations, or other proceedings pending or threatened against any Company,
or in respect of which any Company may have any liability, in any court or
before any governmental authority, arbitration board, or other tribunal, (b) no
orders, writs, injunctions, judgments, or decrees of any court or government
agency or

<PAGE>

instrumentality to which any Company is a party or by which the property or
assets of any Company are bound, and (c) no grievances, disputes, or
controversies outstanding with any union or other organization of the employees
of any Company, or to the knowledge of such Company, threats of work stoppage,
strike, or pending demands for collective bargaining.

TITLE TO ASSETS. Each Company has good title to and ownership of all property it
purports to own, which property is free and clear of all Liens, except those
permitted under Section 5.9 hereto.

LIENS AND SECURITY INTERESTS. On and after the Closing Date, except for Liens
permitted pursuant to Section 5.9 hereof, (a) there are no financing statements
of record covering any personal property of any Company, other than a financing
statement in favor of Bank, if any; (b) there is no mortgage outstanding
covering any real property of any Company, other than a mortgage in favor of
Bank; and (c) no real or personal property of any Company is subject to any
security interest or Lien of any kind other than any security interest or Lien
that may be granted to Bank. Except for Liens permitted pursuant to Section 5.9
hereof, Bank has a valid and enforceable first security interest in the
Collateral. No Company has entered into any contract or agreement that exists on
or after the Closing Date that would prohibit Bank from acquiring a security
interest, mortgage or other Lien on, or a collateral assignment of, any of the
property or assets of any Company.

TAX RETURNS. All federal, state and local tax returns and other reports required
by law to be filed in respect of the income, business, properties and employees
of each Company have been filed and all taxes, assessments, fees and other
governmental charges that are due and payable have been paid, except as
otherwise permitted herein or the failure to do so would not reasonably be
expected to cause or result in a Material Adverse Effect. The provision for
taxes on the books of each Company is adequate for all years not closed by
applicable statutes and for the current fiscal year.

ENVIRONMENTAL LAWS. Except as expressly set forth in the reports and documents
set forth on Schedule 7.8, each Company and the Real Property are in compliance
with any and all Environmental Laws, including, without limitation, all
Environmental Laws in all jurisdictions in which any Company owns or operates,
or has owned or operated, a facility or site, arranges or has arranged for
disposal or treatment of hazardous substances, solid waste or other wastes,
accepts or has accepted for transport any hazardous substances, solid waste or
other wastes or holds or has held any interest in real property or otherwise.
Except as expressly set forth in the reports and documents set forth on Schedule
7.8, no litigation or proceeding arising under, relating to or in connection
with any Environmental Law is pending or, to the best knowledge of each Company,
threatened, against any Company, any real property in which any Company holds or
has held an interest or any past or present operation of any Company. Except as
expressly set forth in the reports and documents set forth on Schedule 7.8, no
release, threatened release or disposal of hazardous substances, hazardous
waste, solid waste or other wastes is occurring, or has occurred (other than
those that are currently being cleaned up in accordance with Environmental
Laws), on, under or to the Real Property or any real property in which any
Company holds any interest or performs any of its operations in violation of any
Environmental Law. As used in this Section, "litigation or proceeding" means any
demand, claim, notice, suit, suit in equity, action, administrative action,
investigation or inquiry whether brought by any governmental authority or
private Person or otherwise.

CONTINUED BUSINESS. There exists no actual, pending, or, to any Borrower's
knowledge, any threatened termination, cancellation or limitation of, or any
modification or change in the business relationship of any Company and any
customer or supplier, or any group of customers or suppliers, whose purchases or
supplies, individually or in the aggregate, are material to the business of any
Company, and there exists no present condition or state of facts or
circumstances that would materially affect adversely any Company in any respect
or prevent a Company from

<PAGE>

conducting such business or the transactions contemplated by this Agreement in
substantially the same manner in which it was previously conducted.

EMPLOYEE BENEFITS PLANS. Schedule 7.10 hereto identifies each ERISA Plan. No
ERISA Event has occurred or is expected to occur with respect to an ERISA Plan.
Full payment has been made of all amounts which a Controlled Group member is
required, under applicable law or under the governing documents, to have been
paid as a contribution to or a benefit under each ERISA Plan. The liability of
each Controlled Group member with respect to each ERISA Plan has been fully
funded based upon reasonable and proper actuarial assumptions, has been fully
insured, or has been fully reserved for on its financial statements. No changes
have occurred or are expected to occur that would cause a material increase in
the cost of providing benefits under the ERISA Plan. With respect to each ERISA
Plan that is intended to be qualified under Code Section 401(a), (a) the ERISA
Plan and any associated trust operationally comply with the applicable
requirements of Code Section 401(a); (b) the ERISA Plan and any associated trust
have been amended to comply with all such requirements as currently in effect,
other than those requirements for which a retroactive amendment can be made
within the "remedial amendment period" available under Code Section 401 (b) (as
extended under Treasury Regulations and other Treasury pronouncements upon which
taxpayers may rely); (c) the ERISA Plan and any associated trust have received a
favorable determination letter from the Internal Revenue Service stating that
the ERISA Plan qualifies under Code Section 401(a), that the associated trust
qualifies under Code Section 501 (a) and, if applicable, that any cash or
deferred arrangement under the ERISA Plan qualifies under Code Section 401(k),
unless the ERISA Plan was first adopted at a time for which the above-described
"remedial amendment period" has not yet expired; (d) the ERISA Plan currently
satisfies the requirements of Code Section 410(b), without regard to any
retroactive amendment that may be made within the above-described "remedial
amendment period"; and (e) no contribution made to the ERISA Plan is subject to
an excise tax under Code Section 4972. With respect to any Pension Plan, the
"accumulated benefit obligation" of Controlled Group members with respect to the
Pension Plan (as determined in accordance with Statement of Accounting Standards
No. 87, "Employers' Accounting for Pensions") does not exceed the fair market
value of Pension Plan assets.

CONSENTS OR APPROVALS. Except as set forth on Schedule 7.11 hereto, no consent,
approval or authorization of, or filing, registration or qualification with, any
governmental authority or any other Person is required to be obtained or
completed by any Company in connection with the execution, delivery or
performance of any of the Loan Documents, that has not already been obtained or
completed.

SOLVENCY. Each Borrower has received consideration that is the reasonable
equivalent value of the obligations and liabilities that Borrower has incurred
to Bank. None of the Borrowers is insolvent as defined in any applicable state
or federal statute, nor will any Borrower be rendered insolvent by the execution
and delivery of the Loan Documents to Bank. None of the Borrowers Borrower is
engaged or about to engage in any business or transaction for which the assets
retained by it are or will be an unreasonably small amount of capital, talking
into consideration the obligations to Bank incurred hereunder. None of the
Borrowers intends to, nor does any Borrower believe that it will, incur debts
beyond its ability to pay such debts as they mature.

FINANCIAL STATEMENTS. The Consolidated financial statements of Borrowers for the
period ended as of June 30, 2004 furnished to Bank, are true and complete in all
material respects, have been prepared in accordance with GAAP, and fairly
present such Person's financial condition as of the dates of such financial
statements and the results of their operations for the periods then ending.

REGULATIONS. None of the Borrowers is engaged principally or as one of its
important activities, in the business of extending credit for the purpose of
purchasing or carrying any "margin stock" (within the meaning of Regulation U of
the Board of Governors of the Federal

<PAGE>

Reserve System of the United States of America). Neither the granting of any
Loan (or any conversion thereof) nor the use of the proceeds of any Loan will
violate, or be inconsistent with, the provisions of Regulation U or X of said
Board of Governors.

MATERIAL AGREEMENTS. Except as disclosed on Schedule 7.15 hereto, no Company is
a party to any (a) debt instrument; (b) lease (capital, operating or otherwise),
whether as lessee or lessor thereunder; (c) contract, commitment, agreement, or
other arrangement involving the purchase or sale of any inventory by it, or the
license of any right to or by it; (d) contract, commitment, agreement, or other
arrangement with any of its "Affiliates" (as such term is defined in the
Securities Exchange Act of 1934, as amended); (e) management or employment
contract or contract for personal services with any of its Affiliates that is
not otherwise terminable at will or on less than ninety (90) days' notice
without liability; (f) collective bargaining agreement; or (g) other contract,
agreement, understanding, or arrangement that, as to subsections (a) through
(f), above, if violated, breached, or terminated for any reason, would have or
would be reasonably expected to have a Material Adverse Effect.

INTELLECTUAL PROPERTY. Each Company owns, possesses, or has the right to use all
of the patents, patent applications, trademarks, service marks, copyrights,
licenses, and rights with respect to the foregoing necessary for the conduct of
its business without any known conflict with the rights of others.

INSURANCE. Each Company maintains insurers insurance with coverage and limits as
required by law and as is customary with Persons engaged in the same businesses
as the Companies. Schedule 7.17 sets forth all insurance carried by the
Companies, setting forth in detail the amount and type of such insurance.

ACCURATE AND COMPLETE STATEMENTS. Neither the Loan Documents nor any written
statement made by any Company in connection with any of the Loan Documents
contains any untrue statement of a material fact or omits a material fact
necessary to make the statements contained therein or in the Loan Documents not
misleading. After due inquiry by Borrowers, there is no known fact that any
Company has not disclosed to Bank that has or would have a Material Adverse
Effect.

DEFAULTS. No Unmatured Event of Default or Event of Default exists hereunder,
nor will any begin to exist immediately after the execution and delivery hereof.

REMEDIES UPON DEFAULT

Notwithstanding any contrary provision or inference herein or elsewhere,

OPTIONAL DEFAULTS. If any Event of Default referred to in Section 8.1, 8.2.,
8.3, 8.4, 8.5, 8.6, 8.7, 8.8 or 8.9 hereof shall occur and is continuing, Bank
shall have the right, in its discretion, to give written notice to Borrowers,
to:

terminate the Commitment and the credits hereby established, if not previously
terminated, and, immediately upon such election, the obligation of Bank to make
any further Loan hereunder immediately shall be terminated, and/or accelerate
the maturity of all of the Debt (if the Debt is not already due and payable),
whereupon all of the Debt shall become and thereafter be immediately due and
payable in full without any

<PAGE>

presentment or demand and without any further or other notice of any kind, all
of which are hereby waived by Borrowers.

AUTOMATIC DEFAULTS. If any Event of Default referred to in Section 8.10 hereof
shall occur:

      the Commitment and the credits hereby established shall automatically and
immediately terminated, if not previously terminated, and Bank thereafter shall
not be under any obligation to grant any further Loan hereunder, and the
principal of and  interest then outstanding on all Notes, and all of the Debt,
shall thereupon become and thereafter be immediately due and payable in full (if
the Debt is not already due and payable), all without any presentment, demand or
notice of any kind, that are hereby waived by Borrowers.

OFFSETS. If there shall exist any Event of Default referred to in Section 8.11
hereof or if the maturity of the Notes is accelerated pursuant to Section 9.1 or
9.2 hereof, Bank shall have the right at any time to set off against, and to
appropriate and apply toward the payment of, any and all Debt then owing by
Borrowers to Bank, whether or not the same shall then have matured, any and all
deposit balances and all other indebtedness then held or owing by Bank to or for
the credit or account of Borrowers, all without notice to or demand upon
Borrowers or any other Person, all such notices and demands being hereby
expressly waived by Borrowers.

COLLATERAL. Upon the occurrence and during the continuance of any Event of
Default, Bank shall have the rights and remedies of a secured party under the
Ohio Revised Code, in addition to the rights and remedies of a secured party
provided elsewhere within this Agreement, in any other writing executed by
Borrowers or otherwise provided by law. Bank may require Borrowers to assemble
the Collateral, that Borrowers agrees to do, and make it available to Bank at a
reasonably convenient place to be designated by Bank. Bank may, with or without
notice to or demand upon Borrowers and with or without the aid of legal process,
make use of such force (to the extent permitted by law) as may be necessary to
enter any premises where the Collateral, or any thereof, may be found and to
take possession thereof (including anything found in or on the Collateral that
is not specifically described in this Agreement, each of which findings shall be
considered to be an accession to and a part of the Collateral) and for that
purpose may pursue the Collateral wherever the same may be found, without
liability for trespass or damage caused thereby to Borrowers. After any delivery
or taking of possession of the Collateral, or any thereof, pursuant to this
Agreement, then, with or without resort to Borrowers personally or any other
Person or property, all of which each Borrower hereby waives, and upon such
terms and in such manner as Bank may deem advisable, Bank, in its discretion,
may sell, assign, transfer and deliver any of the Collateral at any time, or
from time to time. No prior notice need be given to Borrowers or to any Person
in the case of any sale of Collateral that Bank determines to be perishable or
to be declining speedily in value or that is customarily sold in any recognized
market, but in any other case Bank shall give Borrowers not fewer than ten (10)
days' prior notice of either the time and place of any public sale of the
Collateral or of the time after which any private sale or other intended
disposition thereof is to be made. Each Borrower waives advertisement of any
such sale and (except to the extent specifically required by the preceding
sentence) waives notice of any kind in respect of any such sale. At any such
public sale, Bank may purchase the Collateral, or any part thereof, free from
any right of redemption, all of which rights each Borrower hereby waives and
releases. After deducting all Related Expenses, and after paying all claims, if
any, secured by Liens having precedence over this Agreement, Bank may apply the
net proceeds of each such sale to or toward the payment of the Debt, whether or
not then due, in such order and by such division as Bank, in its sole
discretion, may deem advisable. Any excess, to the extent permitted by law,
shall be paid to Borrowers, and each Borrower shall remain liable for any
deficiency. In addition, Bank shall at all times have the

<PAGE>

right to obtain new appraisals of Borrowers or the Collateral, the cost of which
shall be paid by Borrowers.

MISCELLANEOUS

RENEWAL. Upon written notice from Borrowers received by Bank not later than
sixty (60) days before the expiration of the Commitment Period, Borrowers may
request a three hundred sixty four (364) day extension or renewal of the
Revolving Credit Commitment. Upon receipt of such notice, Bank may, but shall
not be obligated to, grant an extension or renewal, in all events on such terms
and conditions (including reasonable fees and expenses) as Bank deems
appropriate in its discretion.

NO WAIVER; CUMULATIVE REMEDIES; RELATIONSHIP OF PARTIES. No omission or course
of dealing on the part of Bank or the holder of any Note in exercising any
right, power or remedy hereunder or under any of the Loan Documents shall
operate as a waiver thereof; nor shall any single or partial exercise of any
such right, power or remedy preclude any other or further exercise thereof or
the exercise of any other right, power or remedy hereunder or under any of the
Loan Documents. The remedies herein provided are cumulative and in addition to
any other rights, powers or privileges held under any of the Loan Documents or
by operation of law, by contract or otherwise. Nothing contained in this
Agreement and no action taken by Bank pursuant hereto shall be deemed to
constitute Borrowers and Bank a partnership, association, joint venture or other
entity. The relationship between each Borrower and Bank with respect to the Loan
Documents and the Related Writings is and shall be solely that of debtor and
creditor, respectively, and Bank shall have no fiduciary obligation toward
Borrowers with respect to any such documents or the transactions contemplated
thereby.

AMENDMENTS, CONSENTS. No amendment, modification, termination, or waiver of any
provision of any Loan Document nor consent to any variance therefrom, shall be
effective unless the same shall be in writing and signed by Bank and Borrowers
and then such waiver or consent shall be effective only in the specific instance
and for the specific purpose for which given.

NOTICES. All notices, requests, demands and other communications provided for
hereunder shall be in writing and, if to a Borrower, mailed or delivered to it,
addressed to it at the address specified on the signature pages of this
Agreement, or if to Bank, mailed or delivered to it, addressed to the address of
Bank specified on the signature pages of this Agreement. All notices,
statements, requests, demands and other communications provided for hereunder
shall be deemed to be given or made when delivered or forty-eight (48) hours
after being deposited in the mails with postage prepaid by registered or
certified mail, addressed as aforesaid, or sent by facsimile with telephonic
confirmation of receipt, except that notices pursuant to any of the provisions
hereof shall not be effective until received. Any notice delivered hereunder by
Bank to one or more Borrowers shall constitute notice thereof to all Borrowers.

COSTS, EXPENSES AND TAXES. Borrowers agree, jointly and severally, to pay on
demand all costs and expenses of Bank, and all Related Expenses, including but
not limited to, (a) administration, travel and out-of-pocket expenses, including
but not limited to attorneys fees and expenses, of Bank in connection with the
preparation, negotiation and closing of the Loan Documents and the
administration of the Loan Documents, the collection and disbursement of all
funds hereunder and the other instruments and documents to be delivered
hereunder, (b) expenses of Bank in connection with the administration of this
Agreement, the Notes and the other instruments and documents to be delivered
hereunder, (c) the reasonable fees and out-of-pocket expenses of special counsel
for Bank, with respect to the foregoing, and of local counsel, if any, who may
be retained by said special counsel with respect thereto, and (d) all costs and
expenses, including reasonable attorneys' fees, in connection with the
restructuring or enforcement of the Debt, this Agreement or any Related Writing.
In addition, Borrowers shall pay any and all stamp and other taxes and fees
payable or determined to be payable in connection with the execution and
delivery of any Loan Document, and the other instruments

<PAGE>

and documents to be delivered hereunder, and agrees to hold Bank harmless from
and against any and all liabilities with respect to or resulting from any delay
in paying or omission to pay such taxes or fees except such liabilities
resulting from the willful misconduct of the Bank.

INDEMNIFICATION. Each Borrower agrees, jointly and severally, to defend,
indemnify and hold harmless Bank from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses (including reasonable attorney fees), or disbursements of any kind or
nature whatsoever that may be imposed on, incurred by or asserted against Bank
in connection with any investigative, administrative or judicial proceeding
(whether or not Bank shall be designated a party thereto) or any other claim by
any Person relating to or arising out of the Loan Documents or any actual or
proposed use of proceeds of the Loans or any of the Debt, or any activities of
any Company or any Obligor or any of their respective affiliates; provided that
Bank shall not have the right to be indemnified under this Section 10.6 for its
own gross negligence or willful misconduct as determined by a court of competent
jurisdiction. All obligations provided for in this Section 10.6 shall survive
any termination of this Agreement.

BINDING EFFECT; ASSIGNMENT. This Agreement shall become effective when it shall
have been executed by Borrowers and Bank and thereafter shall be binding upon
and inure to the benefit of Borrowers and Bank and their respective successors
and assigns, except that no Borrower shall have the right to assign its rights
hereunder or any interest herein without the prior written consent of Bank.

GOVERNING LAW; SUBMISSION TO JURISDICTION. This Agreement, each of the Notes and
any Related Writing shall be governed by and construed in accordance with the
laws of the State of Ohio and the respective rights and obligations of Borrowers
and Bank shall be governed by Ohio law, without regard to principles of conflict
of laws. Each Borrower hereby irrevocably submits to the non-exclusive
jurisdiction of any Ohio state or federal court sitting in Cleveland, Ohio, over
any action or proceeding arising out of or relating to this Agreement, the Debt
or any Related Writing, and each Borrower hereby irrevocably agrees that all
claims in respect of such action or proceeding may be heard and determined in
such Ohio state or federal court in the Northern District of Ohio. Each Borrower
hereby irrevocably waives, to the fullest extent permitted by law, any objection
it may now or hereafter have to the laying of venue in any action or proceeding
in any such court as well as any right it may now or hereafter have to remove
such action or proceeding, once commenced, to another court on the grounds of
FORUM NON CONVENIENS or otherwise. Each Borrower agrees that a final,
nonappealable judgment in any such action or proceeding shall be conclusive and
may be enforced in other jurisdictions by suit on the judgment or in any other
manner provided by law.

SEVERABILITY OF PROVISIONS; CAPTIONS. Any provision of this Agreement that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof or affecting the validity or
enforceability of such provision in any other jurisdiction. The several captions
to sections herein are inserted for convenience only and shall be ignored in
interpreting the provisions of this Agreement.

JOINT AND SEVERAL LIABILITY.

Each Borrower states and acknowledges that: (i) pursuant to this Agreement,
Borrowers desire to utilize their borrowing potential on a consolidated basis to
the same extent possible as if they were merged into a single corporate entity
and that this Agreement reflects the establishment of credit facilities which
would not otherwise be available to such Borrower if each Borrower were not
jointly and severally liable for payment of the obligations; (ii) it has
determined that it will benefit specifically and materially from the advances of
credit contemplated by this Agreement; (iii) it is both a condition precedent to
the obligations of Bank hereunder and a desire of Borrowers that each Borrower
execute and deliver to Bank this Agreement; and (iv) Borrowers

<PAGE>

have requested and bargained for the structure and terms of and security for the
advances contemplated by this Agreement.

Each Borrower shall be liable for all amounts due to Bank from any Borrower
under this Agreement, regardless of which either Borrower actually receives
Loans or other extensions of credit hereunder or the amount of such Loans
received by any Borrower or the manner in which Bank accounts for such Loans or
other extensions of credit on its books and records (without limiting the
foregoing, each Borrower shall be liable for the Loans made to each other
Borrower). Each Borrower's obligations with respect to Loans made to it, and
each Borrower's obligations arising as a result of the joint and several
liability of such Borrower hereunder, with respect to Loans made to another
Borrower hereunder, shall be separate and distinct obligations, but all such
obligations shall be primary obligations of such Borrower.

Each Borrower's obligations arising as a result of the joint and several
liability of such Borrower hereunder with respect to Loans or other extensions
of credit made to another Borrower hereunder shall, to the fullest extent
permitted by law, be unconditional irrespective of (i) the validity or
enforceability, avoidance or subordination of the obligations of any other
Borrower or of any promissory note or other document evidencing all or any part
of the obligations of any other Borrower, (ii) the absence of any attempt to
collect the obligations from any other Borrower, any other guarantor, or any
other security therefor, or the absence of any other action to enforce the same,
(iii) the waiver, consent, extension, forbearance or granting of any indulgence
by Bank with respect to any provision of any instrument evidencing the
obligations of any other Borrower, or any part thereof, or any other agreement
now or hereafter executed by any other Borrower and delivered to Bank, (iv) the
failure by Bank to take any steps to perfect and maintain its security interest
in, or to preserve its rights to, any security or collateral for the obligations
of any other Borrower, (v) Bank's election, in any proceeding instituted under
the Bankruptcy Code, of the application of Section 1111(b)(2) of the United
States Bankruptcy Code, (vi) any borrowing or grant of a security interest by
any other Borrower, as debtor-in-possession under Section 364 of the United
States Bankruptcy Code, (vii) the disallowance of all or any portion of Bank's
claim for the repayment of the obligations of any other Borrower under Section
502 of the United States Bankruptcy Code, or (viii) any other circumstances
which might constitute a legal or equitable discharge or defense of a guarantor
or of any other Borrower. With respect to each Borrower's obligations arising as
a result of the joint and several liability of such Borrower hereunder with
respect to Loans or other extensions of credit made to any Borrower hereunder,
such Borrower waives, until the obligations shall have been paid in full and
this Agreement shall have been terminated, any right to enforce any right of
subrogation or any remedy which Bank now has or may hereafter have against any
other Borrower, any endorser or any guarantor of all or any part of the
obligations, and any benefit of, and any right to participate in, any security
or collateral given to Bank to secure payment of the obligations or any other
liability of any other Borrower to Bank.

Each Borrower agrees if such Borrower's joint and several liability hereunder,
or if any Liens securing such joint and several liability, would, but for the
application of this sentence, be unenforceable under applicable law, such joint
and several liability and each such Lien shall be valid and enforceable to the
maximum extent that would not cause such joint and several liability or such
Lien to be unenforceable under applicable law, and such joint and several
liability and such Lien shall be deemed to have been automatically amended
accordingly at all relevant times. Upon the occurrence and during the
continuance of any Event of Default, Bank may proceed directly and at once,
without notice, against a Borrower to collect and recover the full amount, or
any portion of the obligations, without first proceeding against any other
Borrower or any other Person, or against any security or collateral for the
obligations. Each Borrower consents and agrees that Bank shall be under no
obligation to marshal any assets in favor of such Borrower or against or in
payment of any or all of the obligations.

<PAGE>

Borrowers are obligated to repay the obligations as joint and several obligors
under this Agreement. To the extent that any Borrower shall, under this
Agreement as a joint and several obligor, repay any of the obligations
constituting Loans made to another Borrower hereunder or other obligations
incurred directly and primarily by any other Borrower (an "Accommodation
Payment"), then the Borrower making such Accommodation Payment shall be entitled
to contribution and indemnification from, and, be reimbursed by, each of the
other Borrowers in an amount, for each of such other Borrowers, equal to a
fraction of such Accommodation Payment, the numerator of which fraction is such
other Borrower's "Allocable Amount" (as defined below) and the denominator of
which is the sum of the Allocable Amounts of all of the Borrowers. As of any
date of determination, the "Allocable Amount" of each Borrower shall be equal to
the maximum amount of liability for Accommodation Payments which could be
asserted against such Borrower hereunder without (i) rendering such Borrower
"insolvent" within the meaning of Section 101 (31) of the Bankruptcy Code,
Section 2 of the Uniform Fraudulent Transfer Act ("UFTA") or Section 2 of the
Uniform Fraudulent Conveyance Act ("UFCA"), (ii) leaving such Borrower with
unreasonably small capital or assets, within the meaning of Section 548 of the
United States Bankruptcy Code, Section 4 of the UFTA, or (iii) leaving such
Borrower unable to pay its debts as they become due within the meaning of
Section 548 of the United States Bankruptcy Code or Section 4 of the UFTA, or
Section 5 of the UFCA. All rights and claims of contribution, indemnification
and reimbursement under this Section shall be subordinate in right of payment to
the prior payment in full of the obligations. The provisions of this Section
shall, to the extent expressly inconsistent with any provision in any Loan
Document, supersede such inconsistent provision.

ENTIRE AGREEMENT. This Agreement, any Note, any Related Writing and any other
agreement, document or instrument attached hereto or referred to herein or
executed on or as of the Closing Date integrate all the terms and conditions
mentioned herein or incidental hereto and supersede all oral representations and
negotiations and prior writings with respect to the subject matter hereof.

PATRIOT ACT NOTICE. IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW
ACCOUNT. To help the government fight the funding of terrorism and money
laundering activities, Federal law requires all financial institutions to
obtain, verify, and record information that identifies each person or entity
that opens an account, including any deposit account, treasury management
account, loan, other extension of credit, or other financial services product.
What this means for Borrowers: when a Borrower opens an account, if the Borrower
is an individual, the Bank will ask for the Borrower's name, residential
address, date of birth, and other information that will allow the Bank to
identify the Borrower, and, if the Borrower is not an individual, the Bank will
ask for the Borrower's name, employer identification number, business address,
and other information that will allow the Bank to identify the Borrower. The
Bank may also ask, if the Borrower is an individual, to see the Borrower's
driver's license or other identifying documents, and, if the Borrower is not an
individual, to see the Borrower's legal organizational documents or other
identifying documents.

RULE OF CONSTRUCTION. The Loan Documents were negotiated by the parties with the
benefit of legal representation and any rule of construction or interpretation
otherwise requiring this Agreement or any other Loan Document to be construed or
interpreted against any party shall not apply to any construction or
interpretation hereof or thereof.

for the Subordinated Indebtedness, unless and until all Debt (as defined in the
Credit Agreement) shall have been fully paid and satisfied with interest,
including, but not limited to, any and all post-petition interest owed by or on
account of Borrowers to Lender. All rights, liens and security interests of the
Subordinating Party securing the Subordinated Indebtedness, whether now or
hereafter arising and howsoever existing, in any assets of Borrowers or any
assets securing the Debt shall, be and hereby are subordinated to the rights and
interests of Lender in those assets; and the Subordinating Party shall have no
right to possession of any such assets or to foreclose upon any such assets,
whether by judicial action or otherwise, unless and until all of the Debt shall
have been fully paid and satisfied. The Subordinating Party also hereby agrees
that,

<PAGE>

regardless of whether the Debt is secured or unsecured, the Subordinating Party
shall be subordinated to Lender with respect to the Subordinating Party's claims
against Borrowers with respect to the Subordinated Indebtedness, and the
Subordinating Party's rights, liens and security interest, if any, in any of the
Borrowers' assets and the proceeds thereof (and any other assets securing the
Debt), until all of the Debt shall have been fully paid and satisfied. The
Subordinating Party acknowledges and agrees that, to the extent the terms and
provisions of this Agreement are inconsistent with the Subordinated Note, the
Subordinated Note shall be deemed to have been superseded.

      2. Subordinated Indebtedness Owed Only to Subordinating Party. The
Subordinating Party warrants and represents that it has not previously assigned
any interest in the Subordinated Indebtedness, that no other party owns an
interest in the Subordinated Indebtedness other than the Subordinating Party on
its own behalf and that the entire Subordinated Indebtedness is owing only to
the Subordinating Party on its own behalf. The Subordinating Party agrees that
it will not, and will not allow any other Person to, amend, supplement, amend
and restate, renew, alter or otherwise modify the terms of any of the
Subordinated Indebtedness without the prior written consent of Lender.

      3. Lender's Priority. In the event of any distribution of the assets or
readjustment of the obligations and indebtedness of Borrowers, whether by reason
of liquidation, bankruptcy, arrangement, receivership, assignment for the
benefit of creditors or any other action or proceeding involving the
readjustment of all or any of the Subordinated Indebtedness hereby subordinated,
or the application of the assets of Borrowers to the payment or liquidation
thereof, Lender shall be entitled to receive payment in full of any and all of
the Debt then owing prior to the payment of all or any part of the Subordinated
Indebtedness hereby subordinated.

      4. Grant of Authority to Lender. In the event of any distribution,
division or application, partial or complete, voluntary or involuntary, by
operation of law or otherwise, of all or any part of the assets of any Borrower
or the proceeds thereof, to the creditors of Borrowers, or upon the dissolution
or other winding up of any Borrower's business, or upon the sale of all or
substantially all of any Borrower's assets, then, and in any such event, any
payment or distribution of any kind or character, either in cash, securities or
other property, which shall be payable or deliverable upon or with respect to
any or all of the Subordinated Indebtedness shall be paid or delivered directly
to Lender for application on any of the Debt owing to Lender, due or not due,
until such Debt shall have first been fully paid and satisfied. The
Subordinating Party irrevocably authorizes and empowers Lender to demand, sue
for, collect and receive every such payment or distribution and give acquittance
therefor and, if the Subordinating Party fails to file a claim therefor at least
ten calendar days prior to the date established by rule of law or order of court
for such filing, to file claims and take such other proceedings, in Lender's own
name or in the name of the Subordinating Party or otherwise, as Lender may deem
necessary or advisable for the enforcement of this Agreement; and the
Subordinating Party will execute and deliver to Lender such powers of attorney,
assignments or other instruments or documents as may be requested by Lender in
order to enable Lender to enforce any and all claims upon or with respect to any
or all of the Subordinated Indebtedness and to collect and receive any and all
payments or distributions which may be payable or deliverable at any time upon
or with respect to the Subordinated Indebtedness, all for Lender's own benefit.

      5. Payments Received by Subordinating Party. Should any payment or
distribution or security or instrument or proceeds thereof be received by the
Subordinating Party upon or with respect to the Subordinated Indebtedness or any
other obligations of Borrowers to the

<PAGE>

Subordinating Party prior to the satisfaction of all of the Debt, the
Subordinating Party shall receive and hold the same in trust, as trustee, for
the benefit of Lender and shall forthwith deliver the same to Lender in
precisely the form received (except for the endorsement or assignment of the
Subordinating Party where necessary), for application on any of the Debt, due or
not due, and, until so delivered, the same shall be held in trust by the
Subordinating Party as the property of Lender.

      6. Instrument Legend. Any instrument evidencing any of the Subordinated
Indebtedness (including, without limitation, the Subordinated Note), or any
portion thereof, will, on the date hereof or promptly hereafter, be inscribed
with a legend or other provision conspicuously indicating that payment thereof
is subordinated to the claims of Lender pursuant to the terms of this Agreement,
and a copy thereof will be delivered to Lender on the date hereof or promptly
hereafter. Any instrument evidencing any of the Subordinated Indebtedness, or
any portion thereof, which is hereafter executed by Borrowers, will, on the date
thereof, be inscribed with the aforesaid legend or provision and a copy thereof
will be delivered to Lender on the date of execution or promptly thereafter,
and, upon Lender's request following the occurrence and during the continuance
of an Event of Default, the original thereof will be delivered promptly to
Lender.

      7. Assignment of Claims; Payments and Collateral. The Subordinating Party
agrees that, until the Debt has been paid in full and satisfied, it will not
assign or transfer to others any claims that it has or may have against
Borrowers or any affiliate thereof with respect to the Subordinated
Indebtedness, unless such assignment or transfer is made expressly subject to
this Agreement, and the assignee or transferee expressly agrees in writing to be
subject to the terms and provisions of this Agreement. By the execution of this
Agreement, Borrowers agree not to pay the Subordinating Party any sum on account
of any of the Subordinated Indebtedness or to give the Subordinating Party any
collateral as security therefor at any time when the same would be in breach of
any of the terms of this Agreement.

      8. Continuing Nature of Subordination. This is a continuing agreement of
subordination, and, subject to the terms and conditions hereof, Lender may
continue, at any time, and without notice to the Subordinating Party, to extend
credit or other financial accommodation or benefit and loan monies to or for the
account of Borrowers on the faith hereof. This Agreement shall continue in
effect until the Debt shall have been fully and finally discharged.

      9. Additional Agreements Between Lender and Borrowers. Lender, at any time
and from time to time, may enter into such agreement or agreements with
Borrowers as Lender may deem proper, extending the time of payment of or
renewing or otherwise altering the terms of all or any of the Debt or affecting
the security underlying any or all of the Debt, or may exchange, sell, release,
surrender or otherwise deal with any such security, without in any way impairing
or affecting this Agreement thereby.

      10. Waivers by the Subordinating Party. The Subordinating Party expressly
waives all notice of the acceptance by Lender of the subordination and other
provisions of this Agreement and all other notices whatsoever, and the
Subordinating Party expressly waives reliance by Lender upon the subordination
and other agreements as herein provided. The Subordinating Party agrees that
Lender has not made any warranties or representations with respect to the due
execution, legality, validity, completeness or enforceability of this Agreement,
or the collectibility of the Debt, that Lender shall be entitled to manage and
supervise its loan(s) to Borrowers in accordance with its usual practices,
modified from time to time as Lender deems

<PAGE>

appropriate under the circumstances, without regard to the existence of any
rights that the Subordinating Party may now or hereafter have in or to any of
the assets securing the Subordinated Indebtedness, and that Lender shall not
have any liability to the Subordinating Party for, and the Subordinating Party
waives any claim which it may now or hereafter have against Lender arising out
of, (i) any and all actions which Lender, in good faith, takes or omits to take
including, without limitation, actions with respect to the creation, perfection
or continuation of liens of security interests in the collateral securing the
Debt, actions with respect to the occurrence of an Event of Default (as defined
in the Credit Agreement), with respect to the foreclosure upon, sale, release
of, depreciation of or failure to realize upon, any of the collateral securing
the Debt and actions with respect to the collection of any claim for all or any
part of the Debt or any other agreement related thereto or to the collection of
the Debt or the valuation, use, protection or release of the collateral securing
the Debt, (ii) Lender's election in any proceeding instituted under Chapter 11
of Title 11 of the United States Code (11 U.S.C.Section 101 et seq.) (the
"Bankruptcy Code"), or the application of Section 1111(b) (2) of the Bankruptcy
Code, and/or (iii) any borrowing or grant of a security interest under Section
364 of the Bankruptcy Code.

      11. Bankruptcy Issue. The Subordinating Party agrees that, after the
filing with respect to any Borrower of a petition under the Bankruptcy Code,
Lender may consent to the use of cash collateral or provide financing to such
Borrower on such terms and conditions and in such amounts as Lender, in its sole
discretion, may decide and that, in addition to any liens or security interests
contemplated by the Credit Agreement and in connection with such cash collateral
usage or such financing, such Borrower (or a trustee appointed for the estate of
such Borrower) may grant to Lender, liens and security interests which (i) shall
secure payment of the Debt (whether any portion of the Debt arose prior to the
filing of the petition for relief or arises thereafter) and (ii) shall be
superior in priority to the liens and security interests, if any, held by the
Subordinating Party on any assets of the Borrowers securing the Subordinated
Indebtedness. All allocations of payments between Lender and the Subordinating
Party shall, subject to any court order, continue to be made after the filing of
a petition under the Bankruptcy Code on the same basis that the payments were to
be allocated prior to the date of such filing. The Subordinating Party agrees
that it will not object to or oppose a sale or other disposition of any assets
securing any portion of the Debt free and clear of security interests, liens or
other claims of the Subordinating Party under Section 363 of the Bankruptcy Code
or any other provision of the Bankruptcy Code if Lender has consented to such
sale or disposition of assets. In the event that the Subordinating Party has or
at any time acquires any security for the Subordinated Indebtedness, the
Subordinating Party agrees not to assert any right they may have to "adequate
protection" of their interest in such security in any bankruptcy proceeding and
agree that they will not seek to have the automatic stay lifted with respect to
such security, without the prior written consent of Lender. The Subordinating
Party agrees not to initiate or prosecute any claim, action or other proceeding
(i) challenging the enforceability of any claim of Lender, (ii) challenging the
enforceability of any of the liens or security interests in assets securing all
or any part of the Debt or (iii) asserting any claim which Borrowers may hold
with respect to Lender. To the extent Lender receives payments on, or proceeds
of collateral for, the Debt which 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 cause, then, to the extent of such payment or proceeds
received the Debt, or part thereof, intended to be satisfied shall be revived
and continue in full force and effect as if such payments or proceeds had not
been received by Lender.

<PAGE>

      12. No Waiver. This Agreement shall not be affected, impaired, or released
by the delay or failure of Lender to exercise any of its rights and remedies
against Borrowers, or under any of the Loan Documents or against any collateral
or security for the Debt. No delay or failure on the part of Lender to exercise
any of its rights or remedies hereunder or now or hereafter existing at law or
in equity or by statute or otherwise, or any partial or single exercise thereof,
shall constitute a waiver thereof. All such rights and remedies are cumulative
and may be exercised singly or concurrently and the exercise of any one or more
of them will not be a waiver of any other. No waiver of any of its rights and
remedies hereunder and no modification or amendment of this Agreement shall be
deemed to be made by Lender unless the same shall be in writing, duly signed on
behalf of Lender, and each such waiver, if any, shall apply only with respect to
the specific instance involved and shall in no way impair the rights and
remedies of Lender hereunder in any other respect at any other time.

      13. Information Concerning Financial Condition of Borrowers. The
Subordinating Party hereby assumes responsibility for keeping itself informed of
the financial condition of Borrowers, any and all endorsers and any and all
guarantors of the Debt and of all other circumstances bearing upon the risk of
nonpayment of the Debt and/or indebtedness that diligent inquiry would reveal,
and the Subordinating Party hereby agrees that Lender shall not have any duty to
advise the Subordinating Party of information known to Lender regarding such
condition or any such circumstances. In the event Lender, in its sole
discretion, undertakes, at any time or from time to time, to provide any such
information to the Subordinating Party, Lender shall be under no obligation to
undertake any investigation not a part of its regular business routine and shall
be under no obligation to disclose any information which, pursuant to accepted
or reasonable commercial finance practice, Lender wishes to maintain
confidential. The Subordinating Party hereby assents to any extension or
postponement of the time of payment of the Debt or to any other indulgence with
respect thereto, to any substitution, exchange or release of collateral which
may at any time secure the Debt and/or to the addition or release of any other
party or person primarily or secondarily liable therefor.

      14. Application of Payments. The Subordinating Party hereby agrees that
all payments received by Lender in repayment of the Debt may be applied and
reapplied, in whole or in part, to any of the Debt, as Lender, in its sole
discretion, deems appropriate.

      15. Notices and Communications. All notices, demands, requests and other
communications required under this Agreement shall be in writing and shall be
deemed to have been properly given if sent by hand delivery, Federal Express (or
similar overnight courier service), or by United States certified mail (return
receipt requested), postage prepaid, addressed to the party for whom it is

this Agreement. It is agreed and understood that this waiver constitutes a
waiver of trial by jury of all claims against all parties to such actions or
proceedings, including claims against parties who are not parties to this
Agreement. This waiver is knowingly, willingly and voluntarily made by Borrowers
and the Subordinating Party, and Borrowers and the Subordinating Party hereby
represent that no representations of fact or opinion have been made by any
individual to induce this waiver of trial by jury or to in any way modify or
nullify its effect. Borrowers and the Subordinating Party further represent that
they have been represented in the signing of this Agreement and in the making of
this waiver by independent legal counsel, selected of their own free will, and
that each has had the opportunity to discuss this waiver with counsel.

enforced in accordance with the internal laws of the State of Ohio, without
regard to conflict of laws principles.

personal representatives, successors, and assigns of Borrowers and the
Subordinating Party and shall inure to the benefit of the successors and assigns
of Lender.

      19. Severability. Any provision of this Agreement which is prohibited and
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof or affecting the validity or enforceability of such
provisions in any other jurisdiction.

      20. Section Titles. The section titles contained in this Agreement are and
shall be without substantive meaning or content of any kind whatsoever and are
