<PAGE>   6
         4.1. Borrower is a corporation duly organized, validly existing and in
good standing under the laws of its state of incorporation and is duly qualified
to do business in each state in which a failure to so qualify would have a
material adverse effect on Borrower.

         4.2. Borrower has full power, authority and legal right to grant a
security interest in and collateral assignment of the Collateral, to execute and
deliver this Agreement, and to perform and observe the provisions hereof. The
officers acting on Borrower's behalf have been duly authorized to execute and
deliver this Agreement and to execute and file appropriate financing statements
in respect hereof. This Agreement is valid and binding upon, and enforceable
against, Borrower in accordance with the terms hereof.

         4.3. Neither the execution and delivery of this Agreement, nor the
performance and observance of the provisions hereof, by Borrower will conflict
with, or constitute a violation or default under, any provision of any
applicable law or of any contract (including, without limitation, Borrower's
articles of incorporation or regulations) or of any other writing binding upon
Borrower in any manner.

         4.4. Borrower has places of business or maintains Collateral at the
locations set forth on Schedule 4.4 hereto.

         4.5. Borrower has furnished its most recent financial statements to
Collateral Agent and each of the Creditors and such financial statements are
true and complete in all material respects, have been prepared in accordance
with generally accepted accounting principles, in a manner consistent with that
used for the immediately preceding fiscal period, and fairly present Borrower's
financial condition as of the date of such financial statements and the results
of Borrower's operations for the period then ending, subject, in the case of
unaudited financial statements, to normal audit adjustments. Since such date,
there has been no material adverse change in Borrower's financial condition,
business and properties other than such changes, if any, as have been
specifically disclosed to the Creditors in writing.

         4.6. At the execution and delivery hereof, except as expressly
permitted pursuant to the Credit Agreement and the Note Purchase Agreement, (a)
there is no financing statement outstanding covering the Collateral, or any part
thereof, other than a financing statement in favor of Collateral Agent, for the

equivalent value of the obligations and liabilities that Borrower has incurred
to the Creditors. Borrower is not insolvent, as defined in any applicable state
or federal statute, nor will Borrower be rendered insolvent by the execution and
delivery of this Agreement to Collateral Agent or any other documents

herewith. Borrower has not engaged, nor is Borrower 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, taking into consideration the obligations
to the Creditors incurred hereunder. Borrower does not intend to, nor does it
believe that it will, incur debts beyond its ability to pay such debts as they
mature.

         4.8. At the execution and delivery hereof, after taking into account
the amendments to the Creditor Documents, of even date herewith, no Default
Event will exist.

         5.   Insurance. Borrower shall at all times maintain with financially
sound and reputable insurers reasonably appropriate considering the amount and

same or similar businesses and similarly situated and otherwise as may be
reasonably required by Collateral Agent and each of the Creditors, with

as their interests may appear (loss payable endorsement in favor of Collateral
Agent, for the benefit of the Creditors), and, if required by Collateral Agent,
Borrower shall deposit the policies or certificates of insurance with Collateral
Agent. Any such policies of insurance shall provide for no fewer than thirty
(30) days prior written notice of cancellation to Collateral Agent and each of
the Creditors. Any sums received by Collateral Agent, for the benefit of the
Creditors, in payment of insurance losses, returns, or unearned premiums under
the policies shall be held as Collateral and distributed pursuant to the
Intercreditor Agreement. In the event of failure to provide such insurance as
herein provided, Collateral Agent may, at its option, provide such insurance and
Borrower shall pay to Collateral Agent, upon demand, the cost thereof. Should
Borrower fail to pay such sum to Collateral Agent upon demand, interest shall
accrue thereon, from the date of demand until paid in full, at the Default Rate.

Borrower shall furnish to Collateral Agent or such Creditor such information

Borrower's chief executive office or state of organization. In the event of any
of the foregoing or as a result of any change of applicable law with respect to
the taking of security interests, Borrower hereby authorizes Collateral Agent to
file new U.C.C. financing statements (and Borrower agrees that


                                       7

applicable law or state of organization, and Borrower shall pay all filing and
recording fees and taxes in connection with the filing or recordation of such
financing statements and shall immediately reimburse Collateral Agent therefor
if Collateral Agent pays the same. Such amounts not so paid or reimbursed shall

forthwith upon each request of Collateral Agent or any Creditor, such financial
statements of Borrower's financial condition and operations, as may be required
by any of the Creditor Documents; and (b) forward to Collateral Agent, upon
reasonable request of Collateral Agent, whenever made, such reports and other
documents that are satisfactory to Collateral Agent and the Creditors.

         10.  Transfers, Liens and Modifications Regarding Collateral. Except as
expressly permitted pursuant to this Agreement, Borrower shall not, without
Collateral Agent's prior written consent, sell, assign, transfer or otherwise
dispose of, or grant any option with respect to, or create, incur, or permit to
exist any pledge, lien, mortgage, hypothecation, security interest, charge,
option or any other encumbrance with respect to any of the Collateral, or any
interest therein, or any proceeds thereof, except for the lien and security
interest provided for by this Agreement and any security agreement securing only
Collateral Agent, for the benefit of the Creditors.

         11.  Collateral. Borrower shall:

         (a)  at all reasonable times allow Collateral Agent and each of the

writing of any information that Borrower has or may receive with respect to the

the Collateral in the aggregate or the rights of Collateral Agent or the
Creditors with respect thereto;

         (d)  maintain the Equipment in good operating condition and repair,
ordinary wear and tear excepted, making all necessary replacements thereof so
that the value and operating


                                       8
<PAGE>   9
efficiency thereof shall at all times be maintained and preserved, and inform
Collateral Agent and each of the Creditors together with the delivery of
required financial statements of any additions to or deletions from the
Equipment; provided that Borrower shall at all times have the right to dispose
of obsolete or worn out equipment or replace equipment in the ordinary course of
business to the extent permitted under the Creditor Documents; and

         (e)  upon request of Collateral Agent, promptly take such action and
promptly make, execute, and deliver all such additional and further items,
deeds, assurances, instruments and any other writings as Collateral Agent may
from time to time deem necessary or appropriate, including, without limitation,
financing statements, to carry into effect the intention of this Agreement or so
as to completely vest in and ensure to Collateral Agent and the Creditors their
rights hereunder and in or to the Collateral.

         If certificates of title or applications for title are issued or

upon request of Collateral Agent, (i) execute and deliver to Collateral Agent a
short form security agreement, in form and substance satisfactory to Collateral
Agent, and (ii) deliver such certificate or application to Collateral Agent and

to do so) to incur reasonable Administrative Expenses (whether prior to, upon,
or subsequent to any Default Event hereunder), and Borrower shall promptly
repay, reimburse and indemnify Collateral Agent for any and all Administrative
Expenses. If Borrower fails to keep and maintain the Equipment in good operating
condition, Collateral Agent may (but shall not be required to) so maintain or
repair all or any part of the Equipment and the cost thereof shall be an
Administrative Expense. All Administrative Expenses are payable to Collateral
Agent upon demand therefor.

         12.  Collections and Receipt of Proceeds by Borrower. Prior to exercise
by Collateral Agent of the rights of the Creditors under this Agreement, the
lawful receipt and retention by Borrower of all Proceeds of all of the Inventory
shall be as the agent of Collateral Agent and the Creditors. Upon written notice
to Borrower from Collateral Agent after a Default Event, a Cash Collateral
Account shall be opened by Borrower at the main office of Collateral Agent and
all such lawful collections of the Proceeds of the Inventory shall be remitted
daily by Borrower to Collateral Agent in the form in which they are received by
Borrower, either by mailing or by delivering such collections and Proceeds to
Collateral Agent, appropriately endorsed for deposit in the Cash Collateral
Account. In the event that such notice is given to Borrower from Collateral
Agent, Borrower shall not commingle such collections or Proceeds with any of
Borrower's other funds or property, but shall hold such collections and Proceeds
separate and apart therefrom upon an express trust for Collateral Agent, for the
benefit of the Creditors. In such case, Collateral Agent shall apply all or any
portion of the account balance in the Cash Collateral Account in accordance with
the terms of the Intercreditor Agreement. If any item shall be dishonored, or
if, upon final payment, any claim with respect thereto shall be made against
Collateral Agent on its warranties of collection, Collateral Agent may charge
the amount of such item against the Cash Collateral Account, and, in any event,
retain such item and Borrower's interest therein as additional security for the
Creditor Obligations. Collateral Agent may release funds from the Cash
Collateral Account to Borrower in accordance with the terms of the Intercreditor
Agreement. The balance in the Cash Collateral Account may be withdrawn by
Borrower upon termination of this Agreement and irrevocable payment in full of
all of the Creditor Obligations. At Collateral Agent's request, Borrower shall
cause all remittances

Ohio, to which Collateral Agent shall have access for the processing of such
items in accordance with the provisions, terms, and conditions of a customary
lock box agreement in form and substance satisfactory to the Creditors.

         13.  Collections and Receipt of Proceeds by Collateral Agent. Borrower
hereby constitutes and appoints Collateral Agent, or Collateral Agent's
designated agent, as Borrower's attorney-in-fact to exercise, at any time after
the occurrence of a Default Event, all or any of the following powers which,
being coupled with an interest, shall be irrevocable until the complete and full
payment of all of the Creditor Obligations:

         (a)  to receive, retain, acquire, take, endorse, assign, deliver,
accept and deposit, in Collateral Agent's name or Borrower's name, any and all
Proceeds of Inventory, and any other writings relating to any of the Collateral.
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. Neither Collateral Agent,
Credit Agreement Agent nor any Creditor shall be bound or obligated to take any
action to preserve any rights therein against prior parties thereto; and

         (b)  to accept all collections in any form relating to the Collateral,
including remittances that may reflect deductions, and, at the option of
Collateral Agent, to deposit such collections into the Cash Collateral Account,
if any, or to apply such collections as a payment on the Creditor Obligations in
accordance with the term of the Intercreditor Agreement.

         14.  Use of Inventory, Equipment and Proceeds. Until a Default Event
shall occur, Borrower may, to the extent permitted under the Creditor Documents,
(a) retain possession of and use the 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 the Inventory
in the ordinary course of business, provided, however, that a sale or lease in
the ordinary course of business does not include a transfer in partial or total
satisfaction of any indebtedness; (c) use and consume raw materials or supplies,
the use and consumption of which are necessary in order to carry on Borrower's
business (d) retain, use and expend Proceeds for any lawful purpose; and (e)
replace or dispose of equipment that is obsolete or no longer useful in
Borrower's business.

         15.  Returned or Repossessed Property. If any merchandise or other
property constituting part of the Collateral shall for any reason be returned to
or repossessed by Borrower in any manner, Collateral Agent shall have, for the
benefit of the Creditors, a security interest in such property as security for
the Creditor Obligations. Borrower shall receive the same in trust for
Collateral Agent, and upon Collateral Agent's request whenever made, segregate
such property and label the same as being held for Collateral Agent and
immediately give Collateral Agent a detailed written notice of such return or
repossession and the reason therefor.

         16.  Default and Remedies. Upon the occurrence of an Actionable
Default, and at all times thereafter, Collateral Agent, acting on behalf of the
Creditors, shall have the rights and remedies of a secured party under the Ohio
Revised Code as in effect from time to time, in addition to the rights and
remedies of a secured party provided elsewhere within this Agreement or in any
other Creditor Document or otherwise provided in law or equity. Collateral Agent
may require Borrower to assemble the Collateral, which Borrower agrees to do,
and make it available


                                       10

to Collateral Agent at a reasonably convenient place to be designated by
Collateral Agent. Collateral Agent may, with or without notice to or demand upon
Borrower and with or without the aid of legal process, make use of such force 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 Borrower. After any
delivery or taking of possession of the Collateral, or any thereof, pursuant to
this Agreement, then, with or without resort to Borrower or any other Person or
property, all of which Borrower hereby waives, and upon such terms and in such
manner as Collateral Agent may deem advisable, Collateral Agent, 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 Borrower or to any
other Person in the case of any sale of Collateral that Collateral Agent
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 Collateral
Agent shall give Borrower no 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. 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, Collateral Agent or any Creditor may
purchase the Collateral, or any part thereof, free from any right of redemption,
all of which rights Borrower hereby waives and releases. After deducting all
Administrative Expenses, and after paying all claims, if any, secured by liens
having precedence over this Agreement, Collateral Agent may apply the net
proceeds of each such sale to or toward the payment of the Creditor Obligations,
whether or not then due, in such order as set forth in the Intercreditor
Agreement. Any excess, to the extent permitted by law, shall be paid to
Borrower, and the obligors on the Creditor Obligations shall remain liable for
any deficiency. In addition, Collateral Agent shall at all times have the right
to obtain new appraisals of Borrower or the Collateral, the cost of which shall
be paid by Borrower.

         17.  Interpretation. Each right, power or privilege specified or
referred to in this Agreement is cumulative and in addition to and not in
limitation of any other rights, powers and privileges that Collateral Agent or
the Creditors may otherwise have or acquire by operation of law, by contract or
otherwise. No course of dealing by Collateral Agent or the Creditors in respect
of, nor any omission or delay by Collateral Agent or the Creditors in the
exercise of, any right, power or privilege shall operate as a waiver thereof,
nor shall any single or partial exercise of any such right, power or privilege
preclude any other or further exercise thereof or of any other right, power or
privilege, as Collateral Agent and the Creditors may exercise each such right,
power or privilege either independently or concurrently with others and as often
and in such order as Collateral Agent and the Creditors may deem expedient. No
waiver, consent or other agreement shall be deemed to have been made by
Collateral Agent or the Creditors or be binding upon Collateral Agent or the
Creditors in any case unless specifically granted by Collateral Agent in
writing, and each such writing shall be strictly construed. If, at any time, one
or more provisions of this Agreement is or becomes invalid, illegal or
unenforceable in whole or in part, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.
Borrower hereby authorizes Collateral Agent to file financing statements with
respect to the Collateral. A carbon, photographic, or other reproduction of this
Agreement may be used as a financing statement. The captions to sections herein
are inserted for convenience only and shall be ignored in interpreting the
provisions of this Agreement.

         18.  Notice. All notices, requests, demands and other communications
provided for hereunder shall be in writing and, if to Borrower, Collateral Agent
or any Creditor, mailed or delivered to it, addressed to it at the address
specified in the Intercreditor 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 from Borrower to Collateral Agent or any Creditor pursuant to any
of the provisions hereof shall not be effective until received by Collateral
Agent or such Creditor.

         19.  Governing Law; Submission to Jurisdiction. The provisions of this
Agreement and the respective rights and duties of Borrower, Collateral Agent and
the Creditors hereunder shall be governed by and construed in accordance with
Ohio law, without regard to principles of conflict of laws. 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, any Creditor Document or any other
document, instrument or agreement executed or delivered in connection with any
of the foregoing, and 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. 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.
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.

         20.  Successors and Assigns. This Agreement shall be binding upon
Borrower and Borrower's successors and assigns and shall inure to the benefit of
and be enforceable and exercisable by Collateral Agent on behalf of and for the
benefit of the Creditors and their respective successors and assigns.

         21.  Termination. At such time as the Creditor Obligations shall have
been irrevocably paid in full, any commitments under the Creditor Documents
terminated, and the Creditor Documents terminated, Borrower shall have the right
to terminate this Agreement. Upon written request of Borrower, Collateral Agent
shall promptly execute and deliver to Borrower appropriate termination
statements.

         22.  Entire Agreement. This Agreement integrates all of the terms and
conditions with respect to the Collateral and supersedes all oral
representations and negotiations and prior writings with respect to the subject
matter hereof.
