any of the Inventory normally held by such Debtor for such purpose, use and

obligated on any of the Non-Tangible Collateral, any rebate, refund or allowance
to which such party may be lawfully entitled, and may accept, in connection

to such Non-Tangible Collateral. The Administrative Agent, however, may, at any
time that a Default exists, whether before or after any revocation of such power
and authority or the maturity of any of the Liabilities, notify an Account
Debtor or other Person obligated on Collateral to make payment or otherwise
render performance to or for the benefit of the Administrative Agent, and
enforce, by suit or otherwise, the obligations of an Account Debtor or other
Person obligated on Collateral and exercise the rights of such Debtor with
respect to the obligation of the Account Debtor or other Person obligated on
Collateral to make payment or otherwise render performance to such Debtor and
with respect to any property that secures the obligations of the Account Debtor
or other Person obligated on the Collateral. In connection with the exercise of
such rights and remedies, Administrative Agent may surrender, release or
exchange all or any part of such Collateral, or compromise or extend or renew
for any period (whether or not longer than the original period) any indebtedness
thereunder or evidenced thereby. Upon the request of the Administrative Agent
during the existence of a Default, each Debtor will, at its own expense, notify
any or all parties obligated on any of the Non-Tangible



                                       7


<PAGE>

Collateral to make payment to the Administrative Agent of any amounts due or to
become due thereunder.

     Upon request by the Administrative Agent during the existence of a Default,
each Debtor will forthwith, upon receipt, transmit and deliver to the
Administrative Agent, in the form received, all cash, checks, drafts and other
instruments or writings for the payment of money (properly endorsed, where
required, so that such items may be collected by the Administrative Agent) which
may be received by such Debtor at any time in full or partial payment or
otherwise as Proceeds of any of the Collateral. Except as the Administrative
Agent may otherwise consent in writing, any such items which may be so received
by any Debtor will not be commingled with any other of its funds or property,
but will be held separate and apart from its own funds or property and upon
express trust for the Administrative Agent until delivery is made to the
Administrative Agent. Each Debtor will comply with the terms and conditions of
any consent given by the Administrative Agent pursuant to the foregoing
sentence.

     After the date hereof and following written notice by Administrative Agent
during the existence of a Default, all items or amounts which are delivered by
any Debtor to the Administrative Agent on account of partial or full payment or
otherwise as Proceeds of any of the Collateral shall be deposited to the credit
of a deposit account (an "Assignee Deposit Account") of such Debtor with LaSalle
(or another financial institution selected by the Administrative Agent) over
which the Administrative Agent has sole dominion and control, as security for
payment of the Liabilities. No Debtor shall have any right to withdraw any funds
deposited in the applicable Assignee Deposit Account. The Administrative Agent
may, from time to time, in its discretion, and shall upon request of the
applicable Debtor made not more than once in any week, apply all or any of the
then balance, representing collected funds, in the Assignee Deposit Account
toward payment of the Liabilities, whether or not then due, in such order of
application as required in Section 1.5.3 of the Credit Agreement, and the
Administrative Agent may, from time to time, in its discretion, release all or
any of such balance to the applicable Debtor.

     During the existence of a Default, the Administrative Agent (or any
designee of the Administrative Agent) is authorized to endorse, in the name of
the applicable Debtor, any item, howsoever received by the Administrative Agent,
representing any payment on or other Proceeds of any of the Collateral.

     5. Certificates, Schedules and Reports. Each Debtor will from time to time,
as the Administrative Agent may reasonably request, deliver to the
Administrative Agent such schedules, certificates and internally prepared
reports respecting all or any of the Collateral at the time subject to the
security interest hereunder, and the items or amounts received by such Debtor in
full or partial payment of any of the Collateral, as the Administrative Agent
may reasonably request. Any such schedule, certificate or report shall be
executed by a duly authorized officer of such Debtor and shall be in such form
and detail as the Administrative Agent may reasonably specify. Each Debtor shall
immediately, upon an officer or agent becoming aware, notify the Administrative
Agent of the occurrence of any event causing any loss or depreciation in the
value of its Inventory or other Goods which loss or depreciation is material to
Borrower and its Subsidiaries taken as a whole, and such notice shall specify
the amount of such loss or depreciation.

     Any reasonable out-of-pocket expenses incurred in protecting, preserving or
maintaining any Collateral shall be borne by Debtors. Except as otherwise
expressly set forth in Section 2, whenever a Default shall be existing, the
Administrative Agent shall have the right to bring suit to enforce any or all of
the Intellectual Property or licenses thereunder, in which event the applicable
Debtor shall at the request of the Administrative Agent do any and all lawful
acts and execute any and all proper documents required by the Administrative
Agent in aid of such enforcement, and Debtor shall promptly, upon demand,
reimburse and indemnify the Administrative Agent for all costs and expenses
incurred by the Administrative Agent in the exercise of its rights under this
Section 6. Notwithstanding the foregoing, the Administrative Agent shall have no
obligation or liability regarding the Collateral or any thereof by reason of, or
arising out of, this Agreement.

     7.   Default. Default and Remedies upon a Default.

     (i)  If a Default shall have occurred and be continuing, the Administrative
          Agent may exercise (or cause its sub-agents to exercise) any or all of
          the remedies available to it (or to such sub-agents) under this
          Agreement.

     (ii) Without limiting the generality of the foregoing, if a Default shall
          have occurred and be continuing, the Administrative Agent may exercise
          on behalf of the Lenders all the rights of a secured party under the
          UCC (whether or not in effect in the jurisdiction where such rights
          are exercised) with respect to any Collateral and, in addition, the
          Administrative Agent may, without being required to give any notice,
          except as herein provided or as may be required by mandatory
          provisions of law, withdraw all cash held in the Assignee Deposit
          Account and apply such cash as provided in Section 8 and, if there
          shall be no such cash or if such cash shall be insufficient to pay all
          the Liabilities in full, sell, lease, license or otherwise dispose of
          the Collateral or any part thereof. Notice of any such sale or other
          disposition shall be given to the relevant Debtors as required in
          Section 9.

     8. Application of Proceeds.

     (i)  If a Default shall have occurred and be continuing, the Administrative
          Agent may apply the proceeds of any sale or other disposition of all
          or any part of the Collateral, in the order set forth in Section 1.5.3
          of the Credit Agreement. The Administrative Agent may make such
          distributions hereunder in cash or in kind or, on a ratable basis, in
          any combination thereof.

     (ii) All distributions made by the Administrative Agent pursuant to this
          Section shall be final (except in the event of manifest error) and the
          Administrative Agent shall have no duty to inquire as to the
          application by any Lender or any amount distributed to it.

     9. Authority to Administer Collateral. Each Debtor irrevocably appoints the
Administrative Agent its true and lawful attorney with full power of
substitution, in the name of such Debtor, any Lender or otherwise, for the sole
use and benefit of the Lenders, but at Debtors' expense, to the extent permitted
by law to exercise, at any time and from time to time while a


                                       12


<PAGE>


Default shall have occurred and be continuing, all or any of the following
powers with respect to all or any of such Debtor's Collateral (to the extent
necessary to pay the Liabilities in full):

     (i)   to demand, sue for, collect, receive and give acquittance for any
           and all monies due or to become due upon or by virtue thereof;

     (ii)  to settle, compromise, compound, prosecute or defend any action or
           proceeding with respect thereto;

     (iii) to sell, lease, license or otherwise dispose of the same or the
           Proceeds thereof, as fully and effectually as if the Administrative
           Agent were the absolute owner thereof, and

     (iv)  to extend the time of payment of any or all thereof and to make any
           allowance or other adjustment with reference thereto;

provided that, except in the case of Collateral that is perishable or threatens
to decline speedily in value or is of a type customarily sold on a recognized
market, the Administrative Agent will give the relevant Debtor at least ten (10)
days' prior written notice of the time and place of any public sale thereof or
the time after which any private sale or other intended disposition thereof will
be made.

     10.   Limitation on Duty in Respect of Collateral. Beyond the exercise of
reasonable care in the custody and preservation thereof, the Administrative
Agent will have no duty as to any Collateral in its possession or control or in
the possession or control of any sub-agent or bailee or any income therefrom or
as to the preservation of rights against prior parties or any other rights
pertaining thereto. The Administrative Agent will be deemed to have exercised
reasonable care in the custody and preservation of the Collateral in its
possession or control if such Collateral is accorded treatment substantially
equal to that which it accords its own property, and will not be liable or
responsible for any loss or damage to any Collateral, or for any diminution in
the value thereof, by reason of any act or omission of any sub-agent or bailee
selected by the Administrative Agent in good faith or by reason of any act or
omission by the Administrative Agent pursuant to instructions from the
Administrative Agent, except to the extent that such liability arises from the
Administrative Agent's gross negligence or willful misconduct.

     To the extent that applicable law imposes duties on the Administrative
Agent to exercise remedies in a commercially reasonable manner, each Debtor
acknowledges and agrees that it is not commercially unreasonable for the
Administrative Agent (a) to fail to incur expenses reasonably deemed significant
by the Administrative Agent to prepare Collateral for disposition or otherwise
to complete raw material or work-in-process into finished goods or other
finished products for disposition, (b) to fail to obtain third-party consents
for access to Collateral to be disposed of, or to obtain or, if not required by
other law, to fail to obtain governmental or third-party consents for the
collection or disposition of Collateral to be collected or disposed of, (c) to
fail to exercise collection remedies against Account Debtors or other Persons
obligated on Collateral or to remove liens or encumbrances on or any adverse
claims against Collateral, (d) to exercise collection remedies against Account
Debtors and other Persons obligated on Collateral




                                       13


<PAGE>


directly or through the use of collection agencies and other collection
specialists, (e) to advertise dispositions of Collateral through publications or
media of general circulation, whether or not the Collateral is of a specialized
nature, (f) to contact other Persons, whether or not in the same business as
such Debtor, for expressions of interest in acquiring all or any portion of the
Collateral, (g) to hire one or more professional auctioneers to assist in the
disposition of Collateral, whether or not the collateral is of a specialized
nature, (h) to dispose of Collateral by utilizing Internet sites that provide
for the auction of assets of the types included in the Collateral or that have
the reasonable capability of doing so, or that match buyers and sellers of
assets, (i) to dispose of assets in wholesale rather than retail markets, (j) to
disclaim disposition warranties, including, without limitation, any warranties
of title, (k) to purchase insurance of credit enhancements to insure the
Administrative Agent against risks of loss, collection or disposition of
Collateral, or to provide to the Administrative Agent a guaranteed return from
the collection or disposition of Collateral, or (l) to the extent deemed
appropriate by the Administrative Agent, to obtain the services of other
brokers, investment bankers, consultants and other professionals to assist the
Administrative Agent in the collection or disposition of any of the Collateral.
Each Debtor acknowledges that the purpose of this Section is to provide
non-exhaustive indications of what actions or omissions by the Administrative
Agent would not be commercially unreasonable in the Administrative Agent's
exercise of remedies against the Collateral and that other actions or omissions
by the Administrative Agent shall not be deemed commercially unreasonable solely
on account of not being indicated in this Section. Without limitation upon the
foregoing, nothing contained in this Section shall be construed to grant any
right to a Debtor or to impose any duties on the Administrative Agent that would
not have been granted or imposed by this Agreement or by applicable law in the
absence of this Section.

     11.   General.

     (i)   Any notice from the Administrative Agent to any Debtor, if mailed,
           shall be deemed given five days after the date mailed by prepaid
           registered or certified United States mail (return receipt
           requested), addressed to such Debtor either at such Debtor's
           address shown on Schedule I hereto or at such other address as
           such Debtor shall have specified in writing to the Administrative
           Agent as its address for notices hereunder.

     (ii)  Each of the Debtors agrees to pay all expenses, including reasonable
           attorney's fees and charges (including time charges of attorneys
           who are employees of the Administrative Agent or any Lender) paid
           or incurred by the Administrative Agent or any Lender in
           endeavoring to collect the Liabilities of such Debtor, or any
           part thereof, and in enforcing this Agreement against such
           Debtor, and such obligations will themselves be Liabilities.

     (iii) No delay on the part of the Administrative Agent in the exercise of
           any right or remedy shall operate as a waiver thereof, and no single
           or partial exercise by the Administrative Agent of any right or
           remedy shall preclude other or further exercise thereof or the
           exercise of any other right or remedy.

     (iv)  This Agreement shall remain in full force and effect until all
           Liabilities have been paid in full and all Commitments have
           terminated. If at any time all or any part of



                                       14


<PAGE>



            any payment theretofore applied by the Administrative Agent or
            any Lender to any of the Liabilities is or must be rescinded or
            returned by the Administrative Agent or such Lender for any
            reason whatsoever (including the insolvency, bankruptcy or
            reorganization of any Debtor), such Liabilities shall, for the
            purposes of this Agreement, to the extent that such payment is or
            must be rescinded or returned, be deemed to have continued in
            existence, notwithstanding such application by the Administrative
            Agent or such Lender, and this Agreement shall continue to be
            effective or be reinstated, as the case may be, as to such
            Liabilities, all as though such application by the Administrative
            Agent or such Lender had not been made.

     (v)    This Agreement shall be governed by and construed in accordance
            with the internal laws of the State of Illinois (including,
            without limitation, 735 Illinois Compiled Statutes ss.105/5-5).
            Whenever possible, each provision of this Agreement shall be
            interpreted in such manner as to be effective and valid under
            applicable law, but if any provision of this Agreement shall be
            held to be prohibited or invalid under applicable law, such
            provision shall be ineffective only to the extent of such
            prohibition or invalidity, without invalidating the remainder of
            such provision or the remaining provisions of this Agreement.

     (vi)   The rights and privileges of the Administrative Agent hereunder
            shall inure to the benefit of its successors and assigns.

     (vii)  This Agreement may be executed in any number of counterparts and by
            the different parties hereto on separate counterparts, and each
            such counterpart shall be deemed to be an original, but all such
            counterparts shall together constitute one and the same
            Agreement. Delivery of an executed counterpart of this Agreement
            by telefacsimile shall be equally as effective as delivery of a
            manually executed counterpart of this Agreement. Any party
            delivering an executed counterpart of this Agreement by
            telefacsimile shall also deliver a manually executed counterpart
            of this Agreement, but the failure to deliver a manually executed
            counterpart shall not affect the validity, enforceability, and
            binding effect of this Agreement.

     (viii) At any time after the date of this Agreement, one or more
            additional Persons may become parties hereto by executing and
            delivering to the Administrative Agent a joinder to this
            Agreement together with supplements to the Schedules hereto
            setting forth all relevant information with respect to such party
            as of the date of such delivery. Immediately upon such execution
            and delivery (and without any further action), each such
            additional Person will become a party to, and will be bound by
            all the terms of, this Agreement and the Schedules attached
            hereto shall be deemed to be automatically amended by the
            supplements to the Schedules provided by such Person.

     12.    JURISDICTION; VENUE. ANY LITIGATION BASED HEREON, OR ARISING OUT
OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, SHALL
BE BROUGHT AND MAINTAINED EXCLUSIVELY


                                       15

FOR THE NORTHERN DISTRICT OF ILLINOIS; PROVIDED THAT ANY SUIT SEEKING
ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT THE
ADMINISTRATIVE AGENT'S OPTION, IN THE COURTS OF ANY JURISDICTION WHERE SUCH
COLLATERAL OR OTHER PROPERTY MAY BE FOUND. EACH DEBTOR HEREBY EXPRESSLY AND
IRREVOCABLY SUBMITS TO THE JURISDICTION OF THE COURTS OF THE STATE OF ILLINOIS
AND OF THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS
FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE. EACH DEBTOR FURTHER
IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE
PREPAID, TO THE ADDRESS SET FORTH ON SCHEDULE I HERETO (OR SUCH OTHER ADDRESS AS
IT SHALL HAVE SPECIFIED IN WRITING TO THE ADMINISTRATIVE AGENT AS ITS ADDRESS
FOR NOTICES HEREUNDER) OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF
ILLINOIS. EACH DEBTOR HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO
ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT
FORUM.

     13. JURY TRIAL WAIVER. EACH DEBTOR, THE ADMINISTRATIVE AGENT AND (BY
ACCEPTING THE BENEFITS HEREOF) EACH LENDER PARTY HEREBY WAIVES ANY RIGHT TO A
TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS UNDER
THIS AGREEMENT, ANY NOTE, ANY OTHER LOAN DOCUMENT AND ANY AMENDMENT, INSTRUMENT,
DOCUMENT OR AGREEMENT DELIVERED OR WHICH MAY IN THE FUTURE BE DELIVERED IN
CONNECTION HEREWITH OR THEREWITH OR ARISING FROM ANY FINANCING RELATIONSHIP
EXISTING IN CONNECTION WITH ANY OF THE FOREGOING, AND AGREES THAT ANY SUCH
ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY.

     14. ChoiceParts LLC. In the event that at any time after the date of this
Agreement the ChoiceParts LLC Interest (i) is dealt in or traded on a securities
exchange or in a securities market, (ii) by its terms expressly provides that it
is a security governed by Article 8 of the UCC, (iii) is an investment company
security or (iv) is held in a securities account, a Debtor will promptly notify
the Administrative Agent in writing of such event, and will promptly execute
such documents, and do such other acts or things reasonably deemed appropriate
by Administrative Agent to deliver to Administrative Agent Control of the
ChoiceParts LLC Interest. Each Debtor represents and warrants that none of the
events described in clauses (i), (ii), (iii) or (iv) has occurred and is
existing as of the date of this Agreement. Each Debtor also agrees that if such
Debtor ever receives a certificate representing any of its equity interests in
ChoiceParts LLC, such Debtor shall promptly notify the Administrative Agent and
upon the request of the Administrative Agent, such Debtor agrees that it will
promptly deliver all such certificates accompanied by appropriate membership
powers duly endorsed in blank to the Administrative Agent. No Debtor will
contest in any manner the perfection or priority of Administrative Agent's Lien
on the Choice Parts LLC Interest.

Effective Date, (i) all references made to the Previous Borrower Security
