            ------------------------------


                                       6
<PAGE>

     Each Borrower represents and warrants as follows:

     5.1  Binding Obligation.  This Agreement is the legally valid and binding
          ------------------
obligation of such Borrower, enforceable against such Borrower in accordance
with its terms, except as enforcement may be limited by bankruptcy, insolvency,
reorganization, moratorium, or similar laws or equitable principles relating to
or limiting creditor's rights generally.

     5.2  Location of Equipment and Inventory.  All of the Equipment and
          -----------------------------------
Inventory of each Borrower is located at the places specified on Schedule I.

     5.3  Ownership of Collateral.  Except for the Permitted Encumbrances
          -----------------------
disclosed on Schedule II and the Security Interests, each Borrower owns its
Collateral free and clear of any Lien.  No effective financing statement or
other form of lien notice covering all or any part of the Collateral is on file
in any recording office, except for those in favor of Agent and as disclosed on
Schedule II or filed to perfect Permitted Encumbrances.  Except as disclosed on
Schedule II, none of the Collateral is in the possession of any bailee,
warehouseman, agent, processor or consignee.

     5.4   Office Locations; Fictitious Names.  The chief place of business, the
           ----------------------------------
chief executive office and the office where each Borrower keeps its books and
records are located at the places specified on Schedule I.  No Borrower does
business nor has it done business during the past five years under any trade-
name or fictitious business name except as disclosed on Schedule III.

     5.5  Perfection.  This Agreement, and the filing of appropriate financing
          ----------
statements and delivery of those documents and instruments required to perfect
the Liens granted hereunder, creates a valid, perfected and, except for the
Permitted Encumbrances, first priority security interest in the Collateral
located in the United States, securing the payment of the Secured Obligations,
and all filings and other actions necessary or desirable to perfect and protect
such security interest have been duly taken other than registering the Lien on
certificates of title for titled vehicles.

     5.6  Governmental Authorizations; Consents.  Except for the filing of the
          -------------------------------------
financing statements referred to in Section 5.5 hereof and the registration of
Liens on certificates of title for titled vehicles, no authorization, approval
or other action by, and no notice to or filing with, any governmental authority
or regulatory body or consent of any other Person (including without limitation
any licensor of Intellectual Property or any party to the Purchase Agreement) is
required either (a) for the execution, delivery or performance of this Agreement
by Borrowers, (b) for the grant by Borrowers of the security interest granted
hereby or (c) for the perfection of such Security Interests in Collateral
located in the United States or the exercise by Agent of its rights and remedies
hereunder, other than as may be required by the Federal Assignment of Claims
Act.

     5.7  Accounts.  Each Account constitutes the legally valid and binding
          --------
obligation of the customer obligated to pay the same.  The amount represented by
any Borrower to Agent as owing by each customer is the correct amount actually
and unconditionally owing, except for normal cash


                                       7

<PAGE>

discounts and allowances where applicable. No customer has any defense, set-off,
claim or counterclaim against any Borrower that can be asserted against Agent,
whether in any proceeding to enforce Agent's rights in the Collateral or
otherwise except defenses, set-offs, claims or counterclaims that are not, in
the aggregate, material to the value of the Accounts. None of the Accounts is
evidenced by a promissory note or other instrument other than a check.

     5.8  Intellectual Property.  The Copyrights, Copyright Licenses, Patents,
          ---------------------
Patent Licenses, Trademarks and Trademark Licenses listed on the respective
schedules to each of the Copyright Security Agreements, the Patent Security
Agreements and the Trademark Security Agreements constitute all of the
Intellectual Property owned by Borrowers.  The execution, delivery and
performance of this Agreement by Borrowers will not violate or cause a default
under any of the Intellectual Property or any agreement in connection therewith.

     5.9  Accurate Information.  All information heretofore, herein or hereafter
          --------------------
supplied to Agent by or on behalf of Borrowers with respect to the Collateral is
and will be accurate and complete in all material respects.

     5.10 Credit Agreement Warranties.  Each representation and warranty set
          ---------------------------
forth in the Credit Agreement is true and correct in all material respects and
such representations and warranties are hereby incorporated herein by this
reference with the same effect as though set forth in their entirety herein.

     5.11 Non-Assignable Contracts.  Failure to obtain consents to the
          ------------------------
assignment or granting of a security interest in the Non-Assignable Contracts
will not have, and would not reasonably be expected to have, a Material Adverse
Effect.  The Non-Assignable Contracts are not material to Borrowers and their
Subsidiaries taken as a whole.

SECTION 6.  Further Assurances; Covenants
            -----------------------------

     6.1  Other Documents and Actions.  Subject to the provisions of
          ---------------------------

that Agent may reasonably request, in order to perfect and protect the Security
Interests granted or purported to be granted hereby or to enable Agent to
exercise and enforce its rights and remedies hereunder with respect to any

created hereby and shall instruct such Person to hold all such Collateral for
Agent's account subject to Agent's instructions.

     6.6    Instruments.  Each Borrower will deliver and pledge to Agent all
            -----------

dispositions of Equipment and shall not permit any Equipment to become a fixture
to real estate other than real estate encumbered by the Mortgages.

            -----------------

due or to become due such Borrower under the Accounts.  In connection with such
collections, each Borrower may take (and, after the occurrence and during the
continuance of an Event of Default at Agent's direction, shall take) such action
as such Borrower or Agent may deem necessary or advisable to enforce collection
of the Accounts; provided, that Agent shall have the right at any time after the

any customer or obligor thereof, or allow any credit or discount thereon without

contested in good faith.

     6.13   Collateral Description.  Each Borrower will furnish to Agent, from
            ----------------------

     6.15   Records of Collateral.  Each Borrower shall keep full and accurate

SECTION 7.  Bank Accounts; Collection of Accounts and Payments
            --------------------------------------------------

     On or prior to the Closing Date, Agent and each Borrower shall, at Agent's
request, enter into an Assignment of Deposit Accounts and Bank Agency Agreement
with each financial institution with which such Borrower maintains from time to
time any deposit accounts (general or special).  Pursuant to the Assignment of
Deposit Accounts and Bank Agency Agreement(s) and pursuant hereto, each Borrower
grants, sells, conveys, assigns, transfers, pledges and sets over unto Agent,
for the benefit of Agent and the Lenders, all of such Borrower's right, title
and interest in and to such accounts and all funds at any time paid, deposited,
credited or held in such accounts (whether for collection, provisionally or
otherwise) or otherwise in the possession of such financial institutions, and
each such financial institution shall act as agent and pledgee-in-possession for
Agent in connection therewith.  Following the Closing Date, no Borrower shall
establish any deposit account with any financial institution except in
accordance with the terms of the Credit Agreement.

     Upon the request of Agent from time to time after the occurrence and during
the continuance of an Event of Default, each Borrower shall promptly establish
lock box or blocked accounts (collectively, "Blocked Accounts") in such
Borrower's name with such banks as are acceptable to Agent ("Collecting Banks"),
subject to irrevocable instructions in the form of Exhibit D hereto, to which
the obligors on all Accounts shall directly remit all payments on Accounts and
in which such Borrower will immediately deposit all cash payments made for
Inventory or in respect of Accounts or other cash payments constituting proceeds
of Collateral in the identical form in which such

                                       11
<PAGE>

payment was made, whether by cash or check. In addition, Agent, for the benefit
of Agent and the Lenders, may establish one or more depository accounts at each
Collecting Bank or at a centrally located bank (collectively, the "Depository
Account"). Without limitation of the terms and provisions of the Assignment of
Deposit Accounts and Bank Agency Agreement(s), from and after receipt by any
Collecting Bank of written notice from Agent to such Collecting Bank that an
Event of Default has occurred, all amounts held or deposited in the Blocked
Accounts held by such Collecting Bank shall be transferred to the Depository
Account; provided that, prior to such Collecting Bank's receipt of such notice,
such amounts shall be automatically transferred to such Borrower's operating
account for unrestricted use by such Borrower, provided that any such use is not
prohibited by the Credit Agreement. Subject to the foregoing, each Borrower
hereby agrees that all payments received by Agent or any Lender, whether by
cash, check, wire transfer or any other instrument, whether made to such Blocked
Accounts or otherwise received by Agent or any Lender and whether representing
payments on the Accounts or proceeds of other Collateral, will be the sole and
exclusive property of Agent for the benefit of Lenders. Each Borrower, and any
of its Affiliates, employees, agents or other Persons acting for or in concert
with such Borrower, shall, acting as trustee for Agent and Lenders, receive, as
the sole and exclusive property of Lenders, any monies, checks, notes, drafts or
any other payments relating to and/or representing proceeds of Accounts or other
Collateral which come into the possession or under the control of such Borrower
or any Affiliates, employees, agents or other Persons acting for or in concert
with such Borrower, and immediately upon receipt thereof, such Borrower or such
Persons shall deposit the same or cause the same to be deposited, in kind, in a
Blocked Account. Notwithstanding the foregoing, any amounts contained in Agent's
Depository Account or the Blocked Accounts or otherwise received by Agent in
excess of the Secured Obligations then due and payable shall be the property of
the relevant Borrower and shall promptly be paid over to such Borrower.

SECTION 8.  Agent Appointed Attorney-in-Fact
            --------------------------------

     Each Borrower hereby irrevocably appoints Agent as such  Borrower's
attorney-in-fact, with full authority in the place and stead of such Borrower
and in the name of such Borrower, Agent or otherwise, from time to time after
the occurrence and continuance of an Event of Default in Agent's discretion to
take any action and to execute any instrument that Agent may deem necessary or
advisable to accomplish the purposes of this Agreement, including, without
limitation:

            (a)   to obtain and adjust insurance required to be paid to Agent;

            (b)   to ask, demand, collect, sue for, recover, compound, receive
     and give acquittance and receipts for moneys due and to become due under or
     in respect of any of the Collateral;

            (c)   to receive, endorse, and collect any drafts or other
     instruments, documents and chattel paper, in connection with clauses (a)
     and (b) above;

                                       12
<PAGE>

            (d)   to file any claims or take any action or institute any
     proceedings that Agent may deem necessary or desirable for the collection
     of any of the Collateral or otherwise to enforce the rights of Agent with
     respect to any of the Collateral;

            (e)   to pay or discharge taxes or Liens, levied or placed upon or
     threatened against the Collateral, the legality or validity thereof and the
     amounts necessary to discharge the same to be determined by Agent in its
     sole discretion;

            (f)   to sign and endorse any invoices, freight or express bills,
     bills of lading, storage or warehouse receipts, assignments, verifications
     and notices in connection with Accounts and other documents (including
     without limitation financing statements, continuation statements and other
     documents necessary or advisable to perfect the Security Interests)
     relating to the Collateral; and

            (g)   generally to sell, transfer, pledge, make any agreement with
     respect to or otherwise deal with any of the Collateral as fully and
     completely as though Agent were the absolute owner thereof for all
     purposes, and to do, at Agent's option and Borrowers' expense, at any time
     or from time to time, all acts and things that Agent deems necessary to
     protect, preserve or realize upon the Collateral.

Each Borrower hereby ratifies and approves all acts of Agent made or taken
pursuant to this Section 8.  Neither Agent nor any person designated by Agent
shall be liable for any acts or omissions or for any error of judgment or
mistake of fact or law.  This power, being coupled with an interest, is
irrevocable so long as this Agreement shall remain in force.

SECTION 9.  Transfers and Other Liens
            -------------------------

     Except as otherwise permitted by the Credit Agreement, no Borrower shall:

            (a)   sell, assign (by operation of law or otherwise) or otherwise
     dispose of, or grant any option with respect to, any of the Collateral,
     except that a Borrower may sell Inventory in the ordinary course of
     business; or

            (b)   create or suffer to exist any lien, security interest or other
     charge or encumbrance upon or with respect to any of the Collateral to
     secure indebtedness of any Person except for the Security Interests created
     by this Agreement and Permitted Encumbrances disclosed on Schedule II.

SECTION 10. Remedies
            --------

     If any Event of Default shall have occurred and be continuing, Agent may
exercise in respect of the Collateral, in addition to all other rights and
remedies provided for herein or otherwise available to it, all the rights and
remedies of a secured party on default under the UCC (whether or not the UCC
applies to the affected Collateral) and also may: (a) require any Borrower to,
and each

                                       13
<PAGE>

Borrower hereby agrees that it will, at its expense and upon request of Agent
forthwith, assemble all or part of the Collateral as directed by Agent and make
it available to Agent at a place to be designated by Agent which is reasonably
convenient to both parties; (b) withdraw all cash in any of any Borrower's
accounts and apply such monies in payment of the Secured Obligations in the
manner provided in Section 14; (c) without notice or demand or legal process,
enter upon any premises of any Borrower and take possession of the Collateral;
and (d) without notice except as specified below, sell the Collateral or any
part thereof in one or more parcels at public or private sale, at any of the
Agent's offices or elsewhere, at such time or times, for cash, on credit or for
future delivery, and at such price or prices and upon such other terms as Agent
may deem commercially reasonable. Each Borrower agrees that, to the extent
notice of sale shall be required by law, at least ten days notice to Borrowers
of the time and place of any public sale or the time after which any private
sale is to be made shall constitute commercially reasonable notification. At any
sale of the Collateral, if permitted by law, Agent may bid (which bid may be, in
whole or in part, in the form of cancellation of indebtedness) for the purchase
of the Collateral or any portion thereof for the account of Agent (on behalf of
Agent and the Lenders). Agent shall not be obligated to make any sale of
Collateral regardless of notice of sale having been given. Agent may adjourn any
public or private sale from time to time by announcement at the time and place
fixed therefor, and such sale may, without further notice, be made at the time
and place to which it was so adjourned. To the extent permitted by law, each
Borrower hereby specifically waives all rights of redemption, stay or appraisal
which it has or may have under any law now existing or hereafter enacted.

SECTION 11. License of Intellectual Property
            --------------------------------

     Each Borrower hereby assigns, transfers and conveys to Agent, effective
upon the occurrence and continuance of any Event of Default hereunder, the
nonexclusive right and license to use all Intellectual Property owned or used by
such Borrower together with any goodwill associated therewith, all to the extent
necessary to enable Agent to realize on the Collateral and any successor or
assign to enjoy the benefits of the Collateral.  This right and license shall
inure to the benefit of Agent and all of its successors, assigns and
transferees, whether by voluntary conveyance, operation of law, assignment,
transfer, foreclosure, deed in lieu of foreclosure or otherwise.  Such right and
license is granted free of charge, without requirement that any monetary payment
whatsoever be made to any Borrower by Agent.

SECTION 12. Acquisition Documents
            ---------------------

     If an Event of Default has occurred and is continuing, each Borrower hereby
irrevocably authorizes and empowers Agent to assert, either directly or on
behalf of such Borrower, any claims such Borrower may have, from time to time,
against any other party to the Acquisition Documents or to otherwise exercise
any right or remedy of any Borrower under the Acquisition Documents (including,
without limitation, the right to enforce directly against any party to the
Acquisition Documents all of any Borrower's rights thereunder), and to make all
demands and give all notices and to make all requests required or permitted to
be made by any Borrower under the Acquisition Documents.

                                       14
<PAGE>

SECTION 13. Limitation on Duty of Agent with Respect to Collateral
            ------------------------------------------------------

     Beyond the safe custody thereof, Agent shall have no duty with respect to
any Collateral in its possession or control (or in the possession or control of
any agent or bailee of Agent) or with respect to any income thereon or the
preservation of rights against prior parties or any other rights pertaining
thereto.  Agent shall be deemed to have exercised reasonable care in the custody
and preservation of the Collateral in its possession if the Collateral is
accorded treatment substantially equal to that which it accords its own
property.  Agent shall not be liable or responsible for any loss or damage to
any of the Collateral, or for any diminution in the value thereof, by reason of
the act or omission of any warehouseman, carrier, forwarding agency, consignee
or other agent or bailee selected by Agent in good faith.

SECTION 14. Application of Proceeds
            -----------------------

     Upon the occurrence and during the continuance of an Event of Default, the
proceeds of any sale of, or other realization upon, all or any part of the
Collateral and any cash held in any of any Borrower's accounts shall be applied:
first, to all fees, costs and expenses incurred by Agent or any Lender with
-----
respect to the Credit Agreement, the other Loan Documents or the Collateral
including, without limitation, those described in subsections 1.3(C), 6.4 and
9.1 of the Credit Agreement and in Section 15 hereof; second, to accrued and
                                                      ------
unpaid interest on the Secured Obligations (including any interest which but for
the provisions of the Bankruptcy Code, would have accrued on such amounts);
third, to the principal amounts of the Secured Obligations outstanding; and
-----
fourth, to any other indebtedness or obligations of any Borrower owing to Agent
------
or any Lender.

SECTION 15. Expenses
            --------

     Each Borrower shall pay all insurance expenses and all expenses of
protecting, storing, warehousing, appraising, insuring, handling, maintaining
and shipping the Collateral, all costs, fees and expenses of perfecting and
maintaining the Security Interests, and any and all excise, property, sales and
use taxes imposed by any state, federal or local authority on any of the
Collateral, or with respect to periodic appraisals and inspections of the
Collateral, or with respect to the sale or other disposition thereof.  If any
Borrower fails promptly to pay any portion of the above expenses when due or to
perform any other obligation of any Borrower under this Agreement, Agent or any
other Lender may, at its option, but shall not be required to, pay or perform
the same and charge any Borrower's account for all costs and expenses incurred
therefor and shall provide subsequent notice to such Borrower or Parent of any
amounts so paid, and each Borrower agrees, jointly and severally, to reimburse
Agent or such Lender therefor on demand.  All sums so paid or incurred by Agent
or any other Lender for any of the foregoing, any and all other sums for which
any Borrower may become liable hereunder and all costs and expenses (including
attorneys' fees, legal expenses and court costs) incurred by Agent or any other
Lender in enforcing or protecting the Security Interests or any of their rights
or remedies under this Agreement shall be payable on demand, shall constitute
Secured Obligations, shall bear interest until paid at the highest rate provided
in the Credit Agreement and shall be secured by the Collateral.

SECTION 16. Termination of Security Interests; Release of Collateral
            --------------------------------------------------------

     Upon payment in full of all Secured Obligations (other than contingent
indemnification obligations to the extent no unsatisfied claim giving rise
thereto has been asserted) and the termination of all Commitments, Risk
Participation Agreements and Lender Letters of Credit, the Security Interests
shall terminate and all rights to the Collateral shall revert to Borrowers.
Upon such termination of the Security Interests or release of any Collateral,
Agent will, at the expense of Borrowers, execute and deliver to the relevant
Borrower such documents as such Borrower shall reasonably request to evidence
the termination of the Security Interests or the release of such Collateral, as
the case may be.

SECTION 17. Notices
            -------

     All notices, approvals, requests, demands and other communications
hereunder shall be given in accordance with the notice provisions of the Credit
Agreement.

            -------------------------------

     No failure on the part of Agent to exercise, and no delay in exercising and
no course of dealing with respect to, any right under the Credit Agreement or
this Agreement shall operate as a waiver thereof; nor shall any single or
partial exercise by Agent of any right under the Credit Agreement or this
Agreement preclude any other or further exercise thereof or the exercise of any
other right.  The rights in this Agreement and the Credit Agreement are
cumulative and are not exclusive of any other remedies provided by law.

SECTION 19. Successors and Assigns
            ----------------------

     This Agreement is for the benefit of Agent and Lenders and their successors
and assigns, and in the event of an assignment of all or any of the Secured
Obligations, the rights hereunder, to the extent applicable to the Secured
Obligations so assigned, may be transferred with such Secured Obligations.  This
Agreement shall be binding on Borrowers and their respective successors and
assigns.

SECTION 20. Changes in Writing
            ------------------

     No amendment, modification, termination or waiver of any provision of this
Agreement or consent to any departure by any Borrower therefrom, shall in any
event be effective without the written concurrence of Agent and Borrowers.

SECTION 21. Applicable Law
            --------------

     THIS AGREEMENT SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN
ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF ILLINOIS, WITHOUT REGARD TO
CONFLICTS OF LAWS PRINCIPLES.

                                       16
<PAGE>

SECTION 22.  Failure or Indulgence Not Waiver; Remedies Cumulative
             -----------------------------------------------------

     No failure or delay on the part of Agent or any Lender in the exercise of
any power, right or privilege hereunder shall impair such power, right or
privilege or be construed to be a waiver of any default or acquiescence therein,
nor shall any single or partial exercise of any such power, right or privilege
preclude other or further exercise thereof or any other right, power or
privilege.  All rights and remedies existing under this Agreement are cumulative
to, and not exclusive of, any rights or remedies otherwise available.
