4.    Collections, etc.    Until such time during the existence of a Default as the Agent shall notify such Debtor of the revocation of such power and 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 ordinary course of its business, any raw materials, work in process or materials normally held by such Debtor for such purpose, and use, in the ordinary course of its business (but subject to the terms of the Credit Agreement), the cash proceeds of Collateral and other money which constitutes

5

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.

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.

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

6

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 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,

7

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

8

such sublicensee agrees to be bound by an agreement similar to the next sentence. 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 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 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, merchantability or fitness for a particular purpose, (k) to purchase insurance or credit enhancements to insure the Agent against risks of loss, collection or disposition of Collateral, or to provide to the Agent a guaranteed return from the collection or

9

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 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

10

(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 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

11

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.
