                                         -2-


  D. All products and proceeds of all of the foregoing.

All of the foregoing are herein collectively called the "Collateral".

  The Company agrees to deliver to the Agent, promptly upon receipt and in due
form for transfer (i.e., endorsed in blank or accompanied by stock or bond
powers executed in blank), any Collateral which may at any time or from time to
time be in or come into the possession or control of the Company; and prior to
the delivery thereof to the Agent, such Collateral shall be held by the Company
separate and apart from its other property and in express trust for the Agent.

  3. WARRANTIES; FURTHER ASSURANCES.  The Company warrants to the Agent and each
Lender that:  (a) the Company is (or at the time of any future delivery, pledge,
assignment or transfer thereof will be) the legal and equitable owner of the
Collateral free and clear of all liens, security interests and encumbrances of
every description whatsoever other than the security interest created hereunder;
(b) the pledge and delivery of the Collateral pursuant to this Agreement will
create a valid perfected security interest in the Collateral in favor of the
Agent; (c) all shares of stock referred to in SCHEDULE I hereto are duly
authorized, validly issued, fully paid and non-assessable; (d) as to each Issuer
whose name appears in SCHEDULE I hereto, the Collateral represents on the date
hereof not less than the applicable percent (as shown in SCHEDULE I hereto) of
the total shares of capital stock issued and outstanding of such Issuer; and (e)
the information contained in SCHEDULE I hereto is true and accurate in all
respects.

  So long as any of the Liabilities shall be outstanding or any commitment shall
exist on the part of the Agent or any Lender with respect to the creation of any
Liabilities, the Company (i) shall not, without the express prior written
consent of the Agent, sell, assign, exchange, pledge or otherwise transfer,
encumber, or grant any option, warrant or other right to purchase the stock of
any Issuer which is pledged hereunder, or otherwise diminish or impair any of
its rights in, to or under any of the Collateral; (ii) shall execute such
Uniform Commercial Code financing statements and other documents (and pay the
costs of filing and recording or re-filing and re-recording the same in all
public offices deemed necessary or appropriate by the Agent) and do such other
acts and things, all as the Agent may from time to time reasonably request, to
establish and maintain a valid, perfected security interest in the Collateral
(free of all other liens, claims and rights of third parties whatsoever) to
secure the performance and payment of the Liabilities; (iii) will execute and
deliver to the Agent such stock powers and similar documents relating to the
Collateral, satisfactory in form and substance to the Agent, as the Agent may
reasonably request; and (iv) will furnish the Agent or any Lender such
information concerning the Collateral as the Agent or such Lender may from time
to time reasonably request, and will permit the Agent or any Lender or any
designee of the Agent or any Lender, from time to time at reasonable times and
on reasonable notice, to inspect, audit and make copies of and extracts from all
records and all other papers in the possession of the Company which pertain to
the Collateral, and will, upon request of the Agent at any time when a Default
has occurred and is continuing, deliver to the Agent all of such records and
papers.


                                         -3-


  4. HOLDING IN NAME OF AGENT, ETC.  The Agent may from time to time after the
occurrence and during the continuance of a Default, without notice to the
Company, take all or any of the following actions:  (a) transfer all or any part
of the Collateral into the name of the Agent or any nominee or sub-agent for the
Agent, with or without disclosing that such Collateral is subject to the lien
and security interest hereunder, (b) appoint one or more sub-agents or nominees
for the purpose of retaining physical possession of the Collateral, (c) notify
the parties obligated on any of the Collateral to make payment to the Agent of
any amounts due or to become due thereunder, (d) endorse any checks, drafts or
other writings in the name of the Company to allow collection of the Collateral,
(e) enforce collection of any of the Collateral by suit or otherwise, and
surrender, release or exchange all or any part thereof, or compromise or renew
for any period (whether or not longer than the original period) any obligations
of any nature of any party with respect thereto, and (f) take control of any
proceeds of the Collateral.

  5. VOTING RIGHTS, DIVIDENDS, ETC.  (a) Notwithstanding certain provisions of
SECTION 4 hereof, so long as the Agent has not given the notice referred to in
PARAGRAPH (b) below:

       A.  The Company shall be entitled to exercise any and all voting or
     consensual rights and powers and stock purchase or subscription rights (but
     any such exercise by the Company of stock purchase or subscription rights
     may be made only from funds of the Company not comprising part of the
     Collateral) relating or pertaining to the Collateral or any part thereof
     for any purpose; PROVIDED, HOWEVER, that the Company agrees that it will
     not exercise any such right or power in any manner which would have a
     material adverse effect on the value of the Collateral or any part thereof.

       B.  The Company shall be entitled to receive and retain any and all
     lawful dividends payable in respect of the Collateral which are paid in
     cash by any Issuer if such dividends are permitted by the Credit Agreement,
     but all dividends and distributions in respect of the Collateral or any
     part thereof made in shares of stock or other property or representing any
     return of capital, whether resulting from a subdivision, combination or
     reclassification of Collateral or any part thereof or received in exchange
     for Collateral or any part thereof or as a result of any merger,
     consolidation, acquisition or other exchange of assets to which any Issuer
     may be a party or otherwise or as a result of any exercise of any stock
     purchase or subscription right, shall be and become part of the Collateral
     hereunder and, if received by the Company, shall be forthwith delivered to
     the Agent in due form for transfer (i.e., endorsed in blank or accompanied
     by stock or bond powers executed in blank) to be held for the purposes of
     this Agreement.

       C.  The Agent shall execute and deliver, or cause to be executed and
     delivered, to the Company, all such proxies, powers of attorney, dividend
     orders and other instruments as the Company may reasonably request for the
     purpose of enabling the Company to exercise the rights and powers which it
     is entitled to exercise pursuant to CLAUSE (a) above and to receive the
     dividends which it is authorized to retain pursuant to CLAUSE (b) above.


                                         -4-


  (b)  Upon notice from the Agent during the existence of a Default, and so long
as the same shall be continuing, all rights and powers which the Company is
entitled to exercise pursuant to SECTION 5(a)(A) hereof, and all rights of the
Company to receive and retain dividends pursuant to SECTION 5(a)(B) hereof,
shall forthwith cease, and all such rights and powers shall thereupon become
vested in the Agent which shall have, during the continuance of such Default,
the sole and exclusive authority to exercise such rights and powers and to
receive such dividends.  Any and all money and other property paid over to or
received by the Agent pursuant to this PARAGRAPH (b) shall be retained by the
Agent as additional Collateral hereunder and applied in accordance with the
provisions hereof.

  6.  REMEDIES.  Whenever a Default shall exist, the Agent may exercise from
time to time any rights and remedies available to it under the Uniform
Commercial Code as in effect in Illinois or otherwise available to it.  Without
limiting the foregoing, whenever a Default shall exist the Agent (a) may, to the
fullest extent permitted by applicable law, without notice, advertisement,
hearing or process of law of any kind, (i) sell any or all of the Collateral,
free of all rights and claims of the Company therein and thereto, at any public
or private sale or brokers' board and (ii) bid for and purchase any or all of
the Collateral at any such public sale and (b) shall have the right, for and in
the name, place and stead of the Company, to execute endorsements, assignments,
stock powers and other instruments of conveyance or transfer with respect to all
or any of the Collateral.  The Company hereby expressly waives, to the fullest
extent permitted by applicable law, any and all notices, advertisements,
hearings or process of law in connection with the exercise by the Agent of any
of its rights and remedies during the continuance of a Default.  If any
notification of intended disposition of any of the Collateral is required by
law, such notification, if mailed, shall be deemed reasonably and properly given
if mailed at least ten (10) days before such disposition, postage prepaid,
addressed to the Company, either at the address of the Company shown below, or
at any other address of the Company appearing on the records of the Agent.  Any
proceeds of any of the Collateral may be applied by the Agent to the payment of
expenses in connection with the Collateral, including, without limitation,
reasonable attorneys' fees and legal expenses, 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 (and,
after payment in full of all Liabilities, any excess shall be delivered to the
Company or as a court of competent jurisdiction shall direct).

  The Agent is hereby authorized to comply with any limitation or restriction in
connection with any sale of Collateral as it may be advised by counsel is
necessary in order to (a) avoid any violation of applicable law (including,
without limitation, compliance with such procedures as may restrict the number
of prospective bidders and purchasers and/or further restrict such prospective
bidders or purchasers to Persons who will represent and agree that they are
purchasing for their own account for investment and not with a view to the
distribution or resale of such Collateral) or (b) obtain any required approval
of the sale or of the purchase by any governmental regulatory authority or
official, and the Company agrees that such compliance shall not result in such
sale being considered or deemed not to have been made in a commercially
reasonable manner and that the Agent shall not


                                         -5-


be liable or accountable to the Company for any discount allowed by reason of
the fact that such Collateral is sold in compliance with any such limitation or
restriction.

  7. GENERAL.  The Agent shall be deemed to have exercised reasonable care in
the custody and preservation of the Collateral if it takes such action for that
purpose as the Company shall request 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 rights
with respect to the Collateral against prior parties, or to do any act with
respect to preservation of the Collateral not so requested by the Company, shall
be deemed a failure to exercise reasonable care in the custody or preservation
of any Collateral.

  No delay on the part of the Agent in exercising any right, power or remedy
shall operate as a waiver thereof, and no single or partial exercise of any such
right, power or remedy shall preclude any other or further exercise thereof, or
the exercise of any other right, power or remedy.  No amendment, modification or
waiver of, or consent with respect to, any provision of this Agreement shall be
effective unless the same shall be in writing and signed and delivered by the
Agent, and then such amendment, modification, waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given.

     All notices hereunder shall be in writing (including, without limitation,
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 hereto, 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 shall be
deemed to have been given when received.

  All rights, powers and remedies of the Agent and the Lenders expressed herein
are in addition to all other rights, powers and remedies possessed by them,
including, without limitation, those provided by applicable law or in any other
written instrument or agreement relating to any of the Liabilities or any
security therefor.

  This Agreement has been delivered at Chicago, Illinois, and shall be construed
in accordance with and governed by the internal laws of the State of Illinois.
Wherever 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 such 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
this Agreement.

  This Agreement shall be binding upon the Company and the Agent and their
respective successors and assigns, and shall inure to the benefit of the Company
and the Agent and the successors and assigns of the Agent.


                                         -6-


     This Agreement may be executed in any number of counterparts and by the

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 THE COMPANY, THE AGENT AND (BY ACCEPTING THE BENEFITS HEREOF) EACH
