        4.  Collections, etc. Until such time during the existence of a Default

authority, each Debtor may, in the ordinary course of its business, at its own
expense, sell, lease or furnish under contracts of service any of the Automobile
Inventory normally held by such Debtor for such purpose, use and consume, in the

                                        5

<PAGE>

(but subject to the terms of the Credit Agreement), the cash proceeds of
Collateral and other money which constitutes Collateral. The Agent 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 any parties
obligated on any of the Subject Receivables to make payment to the Agent of any
amounts due or to become due thereunder (but only if the applicable Debtor shall
have failed, within two Business Days after having been requested in writing to
do so by the Agent, to notify such parties to make payment of such amounts to
the Agent) and enforce collection of any of the Subject Receivables by suit or
otherwise and surrender, release or exchange all or any part thereof, or
compromise or extend or renew for any period (whether or not longer than the
original period) any indebtedness thereunder or evidenced thereby.

        When any Debtor or any of its Affiliates (or any shareholder, director,
officer, employee, agent or those Persons acting for or in concert with such
Debtor or an Affiliate of such Debtor) shall receive or otherwise come into
possession or control of any monies, checks, notes, drafts or other payment
items (each, a "Payment Item") representing the purchase price of any Third
Party Sold Receivable sold by such Debtor, then, except as otherwise permitted
in a writing signed by the Agent, such Debtor shall, or shall cause such
Affiliate or such other Person to, deposit the same in kind in precisely the
form in which such Payment Item was received (with all Payment Items endorsed if
necessary for collection) into a Deposit Account maintained in the United States
of America with respect to which the depositary bank has executed the Control
Agreement. Without limiting the foregoing, each Debtor selling any Third Party
Sold Receivable shall instruct the purchaser thereof to remit the purchase price
for such Receivable into such a Deposit Account. During the existence of a
Control Agreement Default, the Agent may issue the Notice (as defined in the
Control Agreement) pursuant to the Control Agreement.

        Upon request by the Agent during the existence of a Default, each Debtor
will forthwith, upon receipt, transmit and deliver to the 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 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 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
in express trust for the Agent until delivery is made to the Agent. Each Debtor
will comply with the terms and conditions of any consent given by the Agent
pursuant to the foregoing sentence.

        During the existence of a Default, all items or amounts which are
delivered by any Debtor to the 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 (each an "Assignee Deposit Account") of such Debtor with a
financial institution selected by the Agent over which the 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 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 the Agent may determine, and the Agent may, from
time to time, in its discretion, release all or any of such balance to the
applicable Debtor.

                                        6

<PAGE>

        At any time that a Default exists, the Agent (or any designee of the
Agent) is authorized to endorse, in the name of the applicable Debtor, any item,
howsoever received by the 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 Agent may request, deliver to the Agent such schedules,
certificates and 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 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 Agent may reasonably specify. Each Debtor shall immediately
notify the Agent of the occurrence of any event causing any loss or depreciation
in the value of its Automobile Inventory or other assets which could reasonably
be expected to have a Material Adverse Effect, and such notice shall specify the
amount of such loss or depreciation.

        6.  Agreements of the Debtors. Each Debtor (a) hereby authorizes the
Agent to file (with or without the signature of such Debtor), and will upon
request of the Agent execute, such financing statements and other documents (and
pay the cost of filing or recording the same in all public offices reasonably
deemed appropriate by the Agent) and do such other acts and things, all as the
Agent may from time to time reasonably deem necessary or request, to establish
and maintain a valid security interest in the Collateral (free of all other
liens, claims and rights of third parties whatsoever, other than Permitted
Liens) to secure the payment of the Liabilities; (b) will keep all its
Automobile Inventory at, will not change its state of incorporation /
organization and will not maintain any place of business at any location other
than, its state of incorporation / organization and address(es) shown on
Schedules I and II hereto or in such other jurisdiction or at such other
addresses of which such Debtor shall have given the Agent not less than thirty
(30) days' prior written notice; (c) will not change its type of organization
from that listed on the financing statements filed on behalf of the Agent or be
the subject of any merger or other corporate reorganization unless the
applicable Debtor shall have given the Agent not less than thirty (30) days'
prior written notice; (d) will keep its records concerning the Subject
Receivables in such a manner as will enable the Agent or its designees to
determine at any time the status of the Subject Receivables; (e) will furnish
the Agent such information concerning such Debtor and the Collateral as the
Agent may from time to time reasonably request; (f) will permit the Agent and
its designees, from time to time, on reasonable notice and at reasonable times
and intervals during normal business hours (or at any time without notice during
the existence of a Default) to inspect such Debtor's Automobile Inventory, and
to inspect, audit and make copies of and extracts from all records and other
papers in the possession of such Debtor pertaining to the Collateral; (g) will,
upon request of the Agent, stamp on its records concerning the Collateral, and
add on all Chattel Paper and Instruments constituting a portion of the
Collateral, a notation, in form satisfactory to the Agent, of the security
interest of the Agent hereunder; (h) except for the sale or lease of Automobile
Inventory in the ordinary course of its business and for dispositions permitted
by Section 9.10 of the Credit Agreement, will not sell, lease, assign or create
or permit to exist any Lien on any Collateral other than Permitted Liens; (i)
will at all times keep all of its Automobile Inventory insured as required by
Section 9.3 of the Credit Agreement and cause all policies covering the
Collateral to provide that loss thereunder shall be payable to the Agent as its
interest may appear (it being understood that (A) so long as no Default shall be
existing, the Agent shall deliver any proceeds of such insurance which may be

                                        7

<PAGE>

received by it to such Debtor and (B) whenever a Default shall be existing, the
Agent may apply any proceeds of such insurance which may be received by it
toward payment of the Liabilities, whether or not due, in such order of
application as the Agent may determine), and such policies or certificates
thereof shall, if the Agent so requests, be deposited with or furnished to the
Agent; (j) will take such actions as are reasonably necessary to keep its
Automobile Inventory in good repair and condition; (k) will take all steps
reasonably necessary to protect, preserve and maintain all of its rights in the
Collateral; (l) will keep all of the Automobile Inventory in the United States;
(m) will not change its name without providing thirty (30) days' prior written
notice to the Agent; (n) if such Debtor has any Commercial Tort Claim against
any Manufacturer arising out of the purchase by such Debtor of Automobile
Inventory from such Manufacturer, and the amount of such Commercial Tort Claim
exceeds $500,000, such Debtor shall provide to the Agent a detailed description
of such Commercial Tort Claim and this Agreement shall be amended to include a
specific reference (sufficient under Section 9-108 of the UCC) to such
Commercial Tort Claim; and (o) acknowledges and agrees that it is not authorized
to file any financing statement in favor of the Agent without the prior written
consent of the Agent and that it will not do so without the prior written
consent of the Agent, subject to such Debtor's rights under Section 9-509(d)(2)
of the UCC.

        Any expenses incurred in protecting, preserving or maintaining any
Collateral shall be borne by the applicable Debtor, and each Debtor shall
promptly, upon demand, reimburse and indemnify the Agent for all reasonable
costs and expenses incurred by the Agent in the exercise of its rights under
this Section 6. Notwithstanding the foregoing, the Agent shall have no
obligation or liability regarding the Collateral or any thereof by reason of, or
arising out of, this Agreement, except to the extent caused by the gross
negligence or wilful misconduct of the Agent.

        7.  Default. During the existence of a Default, the Agent may exercise
from time to time any right or remedy available to it under applicable law. Each
Debtor agrees, in case of Default, to assemble, at its expense, all its
Automobile Inventory that is not then located at one of the inventory locations
listed on the inventory detail report most recently delivered pursuant to
Section 9.1.10 of the Credit Agreement and make it available to the Agent at one
or more of such locations. Any notification of intended disposition of any of
the Collateral required by law shall be deemed reasonably and properly given if
given at least ten days before such disposition. Any proceeds of any disposition
by the Agent of any of the Collateral may be applied by the Agent to payment of
expenses in connection with the Collateral, including Attorney Costs, and any
balance of such proceeds may be applied by the Agent toward the payment of such
of the Liabilities, and in such order of application, as the Agent may from time
to time elect.

        8.  License of Intellectual Property. Each Debtor hereby grants to the
Agent a non-exclusive and royalty-free right and license to use, during the
existence of a Default, all of such Debtor's Intellectual Property throughout
the world, solely for the purpose of enabling the Agent to exercise its rights
and remedies hereunder including, without limitation, the right to use the
Intellectual Property in connection with the disposition or maintenance of
Automobile Inventory as the Agent deems necessary or appropriate. The Agent
shall have the right to grant sublicenses to others to use the Intellectual
Property during the existence of a Default and solely to enable such
sublicensees to exercise any rights and remedies of the Agent under this
Agreement, provided each such sublicensee agrees to be bound by an agreement
similar to the next sentence.

                                        8

<PAGE>

The Agent agrees that it will, when exercising its rights under any Intellectual
Property license hereunder, comply in all material respects with quality
standards and specifications employed by the Debtors in commerce prior to the
Initial Closing Date.

        9.  Limitation on Duty in Respect of Collateral. Beyond the exercise of
reasonable care in the custody and preservation thereof, the 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 Agent shall be deemed to have exercised reasonable care in the
custody and preservation of any of the Collateral in its possession if it takes
such action for that purpose as any applicable Debtor requests in writing, but
failure of the Agent to comply with any such request shall not of itself be
deemed a failure to exercise reasonable care, and no failure of the Agent to
preserve or protect any right with respect to such Collateral against prior
parties, or to do any act with respect to the preservation of such Collateral
not so requested by any Debtor, shall be deemed of itself a failure to exercise
reasonable care in the custody or preservation of such Collateral.

        To the extent that applicable law imposes duties on the Agent to
exercise remedies in a commercially reasonable manner, each Debtor acknowledges
and agrees that it is not commercially unreasonable for the Agent (a) to fail to
incur expenses reasonably deemed significant by the 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 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 the Debtors, 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

the collection or disposition of Collateral or (l) to the extent deemed
appropriate by the Agent, to obtain the services of brokers, investment bankers,
consultants and other professionals to assist the 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 Agent would not be commercially unreasonable in the Agent's
exercise of remedies against the Collateral and that other actions or omissions
by the Agent shall not be deemed commercially unreasonable solely on account of
not being specifically referred to in this Section. Without

                                        9

<PAGE>

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 Agent
that would not have been granted or imposed by this Agreement or by applicable
law in the absence of this Section.

        10. General. All notices hereunder shall be in writing (including
facsimile transmission) and shall be sent to the applicable party at its address
shown below its signature hereto or at such other address as such party may, by
written notice received by the other parties, have designated as its address for
such purpose. Notices sent by facsimile transmission shall be deemed to have
been given when sent; notices sent by mail shall be deemed to have been given
three Business Days after the date when sent by registered or certified mail,
postage prepaid; and notices sent by hand delivery or overnight courier service
shall be deemed to have been given when received.

        Each of the Debtors agrees to pay all reasonable expenses, including
Attorney Costs, paid or incurred by the 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.

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

        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 any payment theretofore applied by the Agent or any
Lender to any of the Liabilities is or must be rescinded or returned by the
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 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 Agent or such Lender had not been made.

        This Agreement shall be construed in accordance with and governed by the
laws of the State of Michigan applicable to contracts made and to be performed
entirely within such State (except to the extent that perfection, the effect of
perfection or nonperfection, or the priority of the security interests granted
hereunder may be determined by the UCC of a different jurisdiction). 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 prohibited by or invalid under applicable law, such provision
shall be ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this
Agreement.

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

        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

                                       10

<PAGE>

original, but all such counterparts shall together constitute one and the same
Agreement. At any time after the date of this Agreement, one or more additional
Persons may become parties hereto by executing and delivering to the Agent a
counterpart of 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.

        EACH DEBTOR HEREBY EXPRESSLY AND IRREVOCABLY SUBMITS TO THE
NON-EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF MICHIGAN AND OF THE
UNITED STATES DISTRICT COURT FOR THE EASTERN DISTRICT OF MICHIGAN FOR THE
PURPOSE OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER OR IN
CONNECTION WITH THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT. EACH DEBTOR FURTHER
IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE
PREPAID, TO THE ADDRESS SET FORTH BELOW ITS SIGNATURE HERETO (OR SUCH OTHER
ADDRESS AS IT SHALL HAVE SPECIFIED IN WRITING TO THE AGENT AS ITS ADDRESS FOR
NOTICES HEREUNDER) OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF
MICHIGAN. 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.

        EACH OF EACH DEBTOR, THE AGENT AND (BY ACCEPTING THE BENEFITS HEREOF)
EACH LENDER 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.
