default under any of the Intellectual Property or any agreement in connection
therewith.

          --------------------
supplied to Agent by or on behalf of such Debtor with respect to the Collateral

improvements in connection therewith that are necessary or desirable to such

     6.16  Other Information.  Each Debtor will, promptly upon Agent's

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

     On or prior to the Closing Date, Agent and Debtor shall enter into an
Assignment of Deposit Accounts and Bank Agency Agreement with each financial
institution with which such Debtor 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 Debtor grants, sells,
conveys, assigns, transfers, pledges and sets over unto Agent, for the benefit
of Agent and the Lenders, all of such Debtor'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 Debtor 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 Debtor shall promptly establish
lock box or blocked accounts (collectively, "Blocked Accounts") in such Debtor'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
Debtor 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 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 Debtor's operating account for unrestricted use by such
Debtor, provided that any such use is not prohibited by the Credit Agreement.
Subject to the foregoing, each Debtor 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 Lenders.  Each
Debtor, and any of its Affiliates, employees, agents or other Persons acting for
or in concert with such Debtor, 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 Debtor or any Affiliates, employees, agents or other Persons acting for
or in concert with such Debtor, and immediately upon receipt thereof, such
Debtor 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

                                       12
<PAGE>

and payable shall be the property of the applicable Debtor and shall promptly be
paid over to such Debtor.

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

     Each Debtor hereby irrevocably appoints Agent as such Debtor's attorney-in-
fact, with full authority in the place and stead of such Debtor and in the name
of such Debtor, Agent or otherwise, from time to time after the occurrence and
during the 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;

           (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 such Debtor's 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 Debtor 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

                                       13
<PAGE>

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 Debtor 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 each Debtor 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 Debtor to, and
each Debtor 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 Debtor'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 Debtor 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 Debtor agrees that, to the extent notice of
sale shall be required by law, at least ten days notice to such Debtor 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 Debtor
hereby specifically waives all rights of redemption, stay or appraisal which it
has or may have under any law now existing or hereafter enacted.

                                       14
<PAGE>

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

     Each Debtor hereby assigns, transfers and conveys to Agent, effective upon
the occurrence and during the continuance of any Event of Default, the
nonexclusive right and license to use all Intellectual Property owned or used by
such Debtor 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 Debtor by Agent.

SECTION 12. Intentionally Omitted
            ---------------------

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 Debtor'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 Debtor owing to Agent or
------
any Lender.

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

     Each Debtor, 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,

                                       15
<PAGE>

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 Debtor fails promptly to pay any portion of the above expenses when due or
to perform any other obligation of such Debtor 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 such Debtor's account for all costs and expenses
incurred therefor and shall provide subsequent notice to such Debtor or Parent
of any amounts so paid, and such Debtor agrees 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 Debtor 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 applicable
Debtor.  Upon such termination of the Security Interests or release of any
Collateral, Agent will, at the expense of Debtors, execute and deliver to
Debtors such documents as Debtors 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.

SECTION 18.  Waivers, Non-Exclusive Remedies
             -------------------------------

     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,

                                       16
<PAGE>

to the extent applicable to the Secured Obligations so assigned, may be
transferred with such Secured Obligations. This Agreement shall be binding on
each Debtor and its 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 Debtor therefrom, shall in any
event be effective without the written concurrence of Agent and such Debtor.

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.

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.

SECTION 23.  Headings
             --------

     Section and subsection headings in this Agreement are included herein for
convenience of reference only and shall not constitute a part of this Agreement
for any other purpose or be given any substantive effect.

SECTION 24.  Counterparts
             ------------

     This Agreement may be executed in any number of counterparts, all of which
taken together shall constitute one and the same instrument and any of the
parties hereto may execute this Agreement by signing any such counterpart.
