Guarantor in trust for the Administrative Agent and the other Secured Parties,

Obligations, whether matured or unmatured, in such order as the Administrative
Agent may determine.

the Administrative Agent nor any other Secured Party shall have any obligation
to protect, secure, perfect or insure any Lien at any time held by it as

of or in connection with any and all of the following: (a) the validity or
enforceability of the Credit Agreement or any other Credit Document, any of the

constitutes, or might be construed to constitute, an equitable or legal
discharge of the Borrower for the Borrower Obligations, or of such Guarantor
under the guarantee contained in this Section 2, in bankruptcy or in any other
instance. When making any demand hereunder or otherwise pursuing its rights and
remedies hereunder against any Guarantor, the Administrative Agent or any other
Secured Party may, but shall be under no obligation to, make a similar demand on
or otherwise pursue such rights and remedies as it may have against the
Borrower, any other Guarantor or any other Person or against any collateral
security or guarantee for the Borrower Obligations or any right of offset with
respect thereto, and any failure by the Administrative Agent or any other
Secured Party to make any such demand, to pursue such other rights or remedies

Person or to realize upon any such collateral security or guarantee or to
exercise any such right of offset, or any release of the Borrower, any other
Guarantor or any other Person or any such collateral security, guarantee or

Secured Party upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of the Borrower or any Guarantor, or upon or as a result of the

          5.3.1  If such Pledgor shall, as a result of its ownership of its

certificate (including, without limitation, any stock certificate representing a
stock dividend or a distribution in connection with any reclassification,

certificate duly executed in blank by such Grantor, to be held by the
Administrative Agent, subject to the terms hereof, as additional collateral

nor shall any Pledgor be required to pledge, more than 65% of any series of the
outstanding Capital Stock of any Foreign Subsidiary Holdco or other Foreign
Subsidiary pursuant to this Agreement).  Any sums paid upon or in respect of the
Pledged Securities upon the liquidation or dissolution of any Issuer or maker
(except any liquidation or dissolution of any Subsidiary of the Borrower in
accordance with the Credit Agreement) shall be paid over to the Administrative
Agent to be held by it hereunder as additional collateral security for the
Obligations, and in case any distribution of capital shall be made on or in

                        SECTION 6.  REMEDIAL PROVISIONS

          6.1  Certain Matters Relating to Accounts.  (a)  At any time and from
               ------------------------------------                            
time to time after the occurrence and during the continuance of an Event of
Default, the Administrative Agent shall have the right to make test
verifications of the Accounts in any reasonable manner and through any
reasonable medium that it reasonably considers advisable, and the relevant
Grantor shall furnish all such assistance and information as the Administrative
Agent may reasonably require in connection with such test verifications.  At any
time and from time to time after the occurrence and during the continuance of an
Event of Default, upon the Administrative Agent's reasonable request and at the
expense of the relevant Grantor, such Grantor shall cause independent public
accountants or others reasonably satisfactory to the Administrative Agent to
furnish to the Administrative Agent reports showing reconciliations, aging and
test verifications of, and trial balances for, the Accounts.

          (b)  The Administrative Agent hereby authorizes each Grantor to
collect such Grantor's Accounts, and the Administrative Agent may curtail or
terminate said authority at any time after the occurrence and during the
continuance of an Event of Default.  If required by the Administrative Agent at
any time after the occurrence and during the continuance of an Event of Default,
any Proceeds constituting collections of such Accounts, when collected by such
Grantor, (i) shall be forthwith (and, in any event, within two Business Days of
receipt by such Grantor) be deposited in or otherwise transferred to the
Collateral Proceeds Account established by such Grantor maintained under the
sole dominion and control of the Administrative Agent, subject to withdrawal by
the Administrative Agent for the account of the Secured Parties only as provided
in Section 65, and (ii) until so turned over, shall be held by such Grantor in
trust for the Administrative Agent and the other Secured Parties, segregated
from other funds of such Grantor. All Proceeds constituting collections of
Accounts while held by the Collateral Account Bank (or by any Guarantor in trust
for the benefit of the Administrative Agent and the other Secured Parties) shall
continue to be collateral security for all of the Obligations and shall not
constitute payment thereof until applied as hereinafter provided. At any time
when an Event of Default has occurred and is continuing, at the Administrative
Agent's election, the Administrative Agent may apply all or any part of the
funds on deposit in the Collateral Proceeds Account established by the relevant
Grantor to the payment of the Obligations of such Grantor 

 
                                                                              23

then due and owing, such application to be made as set forth in Section 6.5
hereof. So long as no Event of Default has occurred and is continuing, the funds
on deposit in the Collateral Proceeds Account shall be remitted as provided in
Section 6.1(d) hereof.

          (c)  At any time and from time to time after the occurrence and during
the continuance of an Event of Default and if the Administrative Agent has
terminated a Grantor's right to collect Accounts pursuant to clause (b) above,
at the Administrative Agent's request, each Grantor shall deliver to the
Administrative Agent all original and other documents evidencing, and relating
to, the agreements and transactions which gave rise to such Grantor's Accounts,
including, without limitation, all original orders, invoices and shipping
receipts.

          (d)  General Fund Account.  So long as no Event of Default has
               --------------------                                     
occurred and is continuing, the Administrative Agent shall instruct the
Collateral Account Bank to promptly remit any funds on deposit in each Grantor's
Collateral Proceeds Account to such Grantor's General Fund Account.  In the
event that an Event of Default has occurred and is continuing, the
Administrative Agent and the Grantors agree that the Administrative Agent, at
its option, may require that each Collateral Proceeds Account be established at
Morgan Guaranty Trust Company of New York.  Each Grantor shall have the right,
at any time and from time to time, to withdraw such of its own funds from its
own General Fund Account, and to maintain such balances in its General Fund
Account, as it shall deem to be necessary or desirable.

          (e)  Restructuring of Deposit Accounts.  If (a) any Collateral
               ---------------------------------                        
Proceeds Account is maintained at a Collateral Account Bank located in a state
within the United States in which Article 9 of the Uniform Commercial Code in
effect in such state has been expressly made applicable to (and only for so long
as it is applicable to) demand deposit accounts and all filings have been made
in such state that are necessary to perfect the Secured Parties' security
interest in such Collateral Proceeds Account or (b) after the Closing Date the
relevant Grantor demonstrates to the Administrative Agent, and the
Administrative Agent in its sole discretion agrees, that the costs associated
with maintaining both a Collateral Proceeds Account and a General Fund Account
outweigh any benefits to the Secured Parties in terms of any additional
protection to their rights in such Grantor's Collateral that could not be
achieved with the use of a single account, then upon the request of such
Grantor, the Administrative Agent may amend this Agreement to delete the
requirement that a separate General Fund Account be maintained and provide that
such Grantor be entitled to withdraw funds on deposit in such Collateral
Proceeds Account at any time so long as no Event of Default has occurred and is
continuing.

          6.2  Communications with Obligors; Grantors Remain Liable.   (a)  The
               ----------------------------------------------------            
Administrative Agent in its own name or in the name of others may at any time
and from time to time after the occurrence and during the continuance of an
Event of Default specified in Section 16.2(a) or 16.3(a) of the Credit
Agreement, communicate with obligors under the Accounts and parties to the
Contracts (in each case, to the extent constituting Collateral) to verify with
them to the Administrative Agent's satisfaction the existence, amount and terms
of any Accounts or Contracts.

          (b)  Upon the request of the Administrative Agent at any time after
the occurrence and during the continuance of an Event of Default specified in
Section 16.2(a) or 16.3(a) of the 

 
                                                                              24

Credit Agreement, each Grantor shall notify obligors on such Grantor's Accounts
and parties to such Grantor's Contracts (in each case, to the extent
constituting Collateral) that such Accounts and such Contracts have been
assigned to the Administrative Agent, for the ratable benefit of the Secured
Parties, and that payments in respect thereof shall be made directly to the
Administrative Agent.

          (c)  Anything herein to the contrary notwithstanding, each Grantor
shall remain liable under each of such Grantor's Accounts to observe and perform
all the conditions and obligations to be observed and performed by it
thereunder, all in accordance with the terms of any agreement giving rise
thereto.  Neither the Administrative Agent nor any Lender shall have any
obligation or liability under any Account (or any agreement giving rise thereto)
by reason of or arising out of this Agreement or the receipt by the
Administrative Agent or any other Secured Party of any payment relating thereto,
nor shall the Administrative Agent or any other Secured Party be obligated in
any manner to perform any of the obligations of any Grantor under or pursuant to
any Account (or any agreement giving rise thereto) to make any payment, to make
any inquiry as to the nature or the sufficiency of any payment received by it or
as to the sufficiency of any performance by any party thereunder, to present or
file any claim, to take any action to enforce any performance or to collect the
payment of any amounts that may have been assigned to it or to which it may be
entitled at any time or times.

          6.3  Pledged Stock.  (a)  Unless an Event of Default shall have
               -------------                                             
occurred and be continuing and the Administrative Agent shall have given notice
to the relevant Pledgor of the Administrative Agent's intent to exercise its
corresponding rights pursuant to Section 6.3(b), each Pledgor shall be permitted
to receive all cash dividends and distributions paid in respect of the Pledged
Stock and all payments made in respect of the Pledged Notes, to the extent
permitted in the Credit Agreement, and to exercise all voting and corporate
rights with respect to the Pledged Stock; provided, however, that no vote shall
                                          --------  -------                    
be cast or corporate right exercised or such other action taken (other than in
connection with a transaction expressly permitted by the Credit Agreement)
which, in the Administrative Agent's reasonable judgment, would materially
impair the Pledged Collateral or the related rights or remedies of the Secured
Parties or which would be inconsistent with or result in any violation of any
provision of the Credit Agreement, this Agreement or any other Credit Document.

          (b)  If an Event of Default shall occur and be continuing and the
Administrative Agent shall give notice of its intent to exercise such rights to
the relevant Pledgor or Pledgors, (i) the Administrative Agent shall have the
right to receive any and all cash dividends, payments or other Proceeds paid in
respect of the Pledged Stock and make application thereof to the Obligations in
such order as is provided in Section 6.5, and (ii) any or all of the Pledged
Stock shall be registered in the name of the Administrative Agent or its
nominee, and the Administrative Agent or its nominee may thereafter exercise (x)
all voting, corporate and other rights pertaining to such Pledged Stock at any
meeting of shareholders of the relevant Issuer or Issuers or otherwise and (y)
any and all rights of conversion, exchange, subscription and any other rights,
privileges or options pertaining to such Pledged Stock as if it were the
absolute owner thereof (including, without limitation, the right to exchange at
its discretion any and all of the Pledged Stock upon the merger, consolidation,
reorganization, recapitalization or other fundamental change in the corporate
structure of any Issuer, or upon the exercise by the relevant 

 
                                                                              25

Pledgor or the Administrative Agent of any right, privilege or option pertaining
to such Pledged Stock, and in connection therewith, the right to deposit and
deliver any and all of the Pledged Stock with any committee, depositary,
transfer agent, registrar or other designated agency upon such terms and
conditions as the Administrative Agent may reasonably determine), all without
liability (other than for its gross negligence or willful misconduct) except to
account for property actually received by it, but the Administrative Agent shall
have no duty to any Pledgor to exercise any such right, privilege or option and
shall not be responsible for any failure to do so or delay in so doing, provided
                                                                        --------
that the Administrative Agent shall not exercise any voting or other consensual
rights pertaining to the Pledged Stock in any way that would constitute an
exercise of the remedies described in Section 6.6 other than in accordance with
Section 6.6.

          (c)  Each Pledgor hereby authorizes and instructs each Issuer or maker
of any Pledged Securities pledged by such Pledgor hereunder to (i) comply with
any instruction received by it from the Administrative Agent in writing that (x)
states that an Event of Default has occurred and is continuing and (y) is
otherwise in accordance with the terms of this Agreement, without any other or
further instructions from such Pledgor, and each Pledgor agrees that each Issuer
or maker shall be fully protected in so complying, and (ii) unless otherwise
expressly permitted hereby, pay any dividends or other payments with respect to
the Pledged Securities directly to the Administrative Agent.

          6.4  Proceeds to be Turned Over To Administrative Agent.  In addition
               --------------------------------------------------              
to the rights of the Administrative Agent and the other Secured Parties
specified in Section 6.1 with respect to payments of Accounts, if an Event of
Default shall occur and be continuing, and the Administrative Agent shall have
instructed any Grantor to do so, all Proceeds received by such Grantor
consisting of cash, checks and other Cash Equivalent items shall be held by such
Grantor in trust for the Administrative Agent and the other Secured Parties,
segregated from other funds of such Grantor, and shall, forthwith upon receipt
by such Grantor, be turned over to the Administrative Agent in the exact form
received by such Grantor (duly indorsed by such Grantor to the Administrative
Agent, if required).  All Proceeds received by the Administrative Agent
hereunder shall be held by the Administrative Agent in the relevant Collateral
Proceeds Account maintained under its sole dominion and control.  All Proceeds
while held by the Administrative Agent in such Collateral Proceeds Account (or
by such Grantor in trust for the Administrative Agent and the other Secured
Parties) shall continue to be held as collateral security for all the
Obligations and shall not constitute payment thereof until applied as provided
in Section 65.

          6.5  Application of Proceeds.  It is agreed that if an Event of
               -----------------------                                   
Default shall occur and be continuing, any and all Proceeds of the relevant
Granting Party's Security Collateral received by the Administrative Agent
(whether from the relevant Granting Party or otherwise) shall be held by the
Administrative Agent for the benefit of the Secured Parties as collateral
security for the Obligations of the relevant Granting Party (whether matured or
unmatured), and/or then or at any time thereafter may, in the sole discretion of
the Administrative Agent, be applied by the Administrative Agent against the
Obligations of the relevant Granting Party then due and owing in the following
order of priority:

          FIRST, to the payment of all reasonable costs and expenses incurred by
     the Administrative Agent in connection with this Agreement, the Credit
     Agreement, any 

 
                                                                              26

     other Credit Document or any of the Obligations of the relevant Granting
     Party, including, without limitation, all court costs and the reasonable
     fees and expenses of its agents and legal counsel, and any other reasonable
     costs or expenses incurred in connection with the exercise by the
     Administrative Agent of any right or remedy under this Agreement, the
     Credit Agreement, or any other Credit Document;

          SECOND, to the ratable satisfaction of all other Obligations of the
     relevant Granting Party; and

          THIRD, to the relevant Granting Party or its successors or assigns, or
     to whomsoever may be lawfully entitled to receive the same.

          6.6  Code and Other Remedies.  If an Event of Default shall occur and
               -----------------------                                         
be continuing, the Administrative Agent, on behalf of the Secured Parties, may
exercise, in addition to all other rights and remedies granted to them in this
Agreement and in any other instrument or agreement securing, evidencing or
relating to the Obligations to the extent permitted by applicable law, all
rights and remedies of a secured party under the Code or any other applicable
law.  Without limiting the generality of the foregoing, to the extent permitted
by applicable law, the Administrative Agent, without demand of performance or
other demand, presentment, protest, advertisement or notice of any kind (except
any notice required by law referred to below) to or upon any Granting Party or
any other Person (all and each of which demands, defenses, advertisements and
notices are hereby waived), may in such circumstances forthwith collect,
receive, appropriate and realize upon the Security Collateral, or any part
thereof, and/or may forthwith sell, lease, assign, give option or options to
purchase, or otherwise dispose of and deliver the Security Collateral or any
part thereof (or contract to do any of the foregoing), in one or more parcels at
public or private sale or sales, at any exchange, broker's board or office of
the Administrative Agent or any other Secured Party or elsewhere upon such terms
and conditions as it may deem advisable and at such prices as it may deem best,
for cash or on credit or for future delivery without assumption of any credit
risk.  The Administrative Agent or any other Secured Party shall have the right
upon any such public sale or sales, and, to the extent permitted by law, upon
any such private sale or sales, to purchase the whole or any part of the
Security Collateral so sold, free of any right or equity of redemption in any
Granting Party, which right or equity is hereby waived or released. Each
Granting Party further agrees, at the Administrative Agent's request, to
assemble the Security Collateral and make it available to the Administrative
Agent at places which the Administrative Agent shall reasonably select, whether
at such Granting Party's premises or elsewhere. The Administrative Agent shall
apply the net proceeds of any action taken by it pursuant to this Section 6.6,
after deducting all reasonable costs and expenses of every kind incurred in
connection therewith or incidental to the care or safekeeping of any of the
Security Collateral or in any way relating to the Security Collateral or the
rights of the Administrative Agent and the other Secured Parties hereunder,
including, without limitation, reasonable attorneys' fees and disbursements, to
the payment in whole or in part of the Obligations of the relevant Granting
Party then due and owing (including, without limitation, to the extent required
by Section 16.4 of the Credit Agreement to cash collateralize L/C Obligations
outstanding at such time), in the order of priority specified in Section 6.5
above, and only after such application and after the payment by the
Administrative Agent of any other amount required by any provision of law,
including, without limitation, Section 9-504(1)(c) of the Code, need the

 
                                                                              27

Administrative Agent account for the surplus, if any, to any Granting Party. To
the extent permitted by applicable law, each Granting Party waives all claims,
damages and demands it may acquire against the Administrative Agent or any other
Secured Party arising out of the repossession, retention or sale of collateral,
except to the extent arising as a result of the gross negligence or willful
misconduct of the Administrative Agent or such other Secured Party. If any
notice of a proposed sale or other disposition of Collateral shall be required
by law, such notice shall be deemed reasonable and proper if given at least 10
days before such sale or other disposition.

          6.7  Registration Rights.  (a)  If the Administrative Agent shall
               -------------------                                         
determine to exercise its right to sell any or all of the Pledged Stock pursuant
to Section 6.6, and if in the reasonable opinion of the Administrative Agent it
is necessary or reasonably advisable to have the Pledged Stock, or that portion
thereof to be sold, registered under the provisions of the Securities Act, the
relevant Pledgor will use its reasonable best efforts to cause the Issuer
thereof to (i) execute and deliver, and use its best efforts to cause the
directors and officers of such Issuer to execute and deliver, all such
instruments and documents, and do or cause to be done all such other acts as may
be, in the reasonable opinion of the Administrative Agent, necessary or
advisable to register such Pledged Stock, or that portion thereof to be sold,
under the provisions of the Securities Act, (ii) use its reasonable best efforts
to cause the registration statement relating thereto to become effective and to
remain effective for a period of not more than one year from the date of the
first public offering of such Pledged Stock, or that portion thereof to be sold,
and (iii) make all amendments thereto and/or to the related prospectus which, in
the reasonable opinion of the Administrative Agent, are necessary or advisable,
all in conformity with the requirements of the Securities Act and the rules and
regulations of the Securities and Exchange Commission applicable thereto.  Such
Pledgor agrees to cause such Issuer to comply with the provisions of the
securities or "Blue Sky" laws of any and all states and the District of Columbia
that the Administrative Agent shall reasonably designate and to make available
to its security holders, as soon as practicable, an earnings statement (which
need not be audited) that will satisfy the provisions of Section 11(a) of the
Securities Act.

          (b)  Such Pledgor recognizes that the Administrative Agent may be
unable to effect a public sale of any or all such Pledged Stock, by reason of
certain prohibitions contained in the Securities Act and applicable state
securities laws or otherwise, and may be compelled to resort to one or more
private sales thereof to a restricted group of purchasers which will be obliged
to agree, among other things, to acquire such securities for their own account
for investment and not with a view to the distribution or resale thereof. Such
Pledgor acknowledges and agrees that any such private sale may result in prices
and other terms less favorable than if such sale were a public sale and,
notwithstanding such circumstances, agrees that any such private sale shall be
deemed to have been made in a commercially reasonable manner. The Administrative
Agent shall be under no obligation to delay a sale of any of the Pledged Stock
for the period of time necessary to permit the Issuer thereof to register such
securities for public sale under the Securities Act, or under applicable state
securities laws, even if such Issuer would agree to do so.

          (c)  Such Pledgor agrees to use its reasonable best efforts to do or
cause to be done all such other acts as may be necessary to make such sale or
sales of all or any portion of 

 
                                                                              28

such Pledged Stock pursuant to this Section 6.7 valid and binding and in
compliance with any and all other applicable Requirements of Law. Such Pledgor
further agrees that a breach of any of the covenants contained in this Section
6.7 will cause irreparable injury to the Administrative Agent and the Lenders,
that the Administrative Agent and the Lenders have no adequate remedy at law in
respect of such breach and, as a consequence, that each and every covenant
contained in this Section 6.7 shall be specifically enforceable against such
Pledgor, and to the extent permitted by applicable law, such Pledgor hereby
waives and agrees not to assert any defenses against an action for specific
performance of such covenants except for a defense that no Event of Default has
occurred or is continuing under the Credit Agreement.

          6.8  Waiver; Deficiency.  Each Granting Party (other than the
               ------------------                                      
Borrower) waives and agrees not to assert any rights or privileges that it may
acquire under Section 9-112 of the Code, to the extent permitted by applicable
law.  Each Granting Party shall remain liable for any deficiency if the proceeds
of any sale or other disposition of the Security Collateral are insufficient to
pay in full, the Loans, Reimbursement Obligations (including, without
limitation, any L/C Obligations which subsequently become Reimbursement
Obligations) and, to the extent then due and owing, all other Obligations of
such Granting Party and the reasonable fees and disbursements of any attorneys
employed by the Administrative Agent or any other Secured Party to collect such
deficiency.


                      SECTION 7.  THE ADMINISTRATIVE AGENT

          7.1  Administrative Agent's Appointment as Attorney-in-Fact, etc.  (a)
               ------------------------------------------------------------
Each Granting Party hereby irrevocably constitutes and appoints the
Administrative Agent and any authorized officer or agent thereof, with full
power of substitution, as its true and lawful attorney-in-fact with full
irrevocable power and authority in the place and stead of such Granting Party
and in the name of such Granting Party or in its own name, for the purpose of
carrying out the terms of this Agreement, to take any and all appropriate action
and to execute any and all documents and instruments that may be reasonably
necessary or desirable to accomplish the purposes of this Agreement to the
extent permitted by applicable law, provided that the Administrative Agent
agrees not to exercise such power except upon the occurrence and during the
continuance of an Event of Default.  Without limiting the generality of the
foregoing, at any time when an Event of Default has occurred and is
continuing (in each case to the extent permitted by applicable law), (x) each
Pledgor hereby gives the Administrative Agent the power and right, on behalf of
such Pledgor, without notice or assent by such Pledgor, to execute, in
connection with any sale provided for in Section 6.6 or 6.7, any indorsements,
assessments or other instruments of conveyance or transfer with respect to such
Pledgor's Pledged Collateral, and (y) each Grantor hereby gives the
Administrative Agent the power and right, on behalf of such Grantor, without
notice to or assent by such Grantor, to do any or all of the following:

          (i)  in the name of such Grantor or its own name, or otherwise, take
     possession of and indorse and collect any checks, drafts, notes,
     acceptances or other instruments for the payment of moneys due under any
     Account of such Grantor that constitutes Collateral or with respect to any
     other Collateral of such Grantor and file any claim or take any other
     action or institute any proceeding in any court of law or equity or
     otherwise deemed 

 
                                                                              29

     appropriate by the Administrative Agent for the purpose of collecting any
     and all such moneys due under any Account of such Grantor that constitutes
     Collateral or with respect to any other Collateral of such Grantor whenever
     payable;

          (ii)  in the case of any Copyright, Patent or Trademark constituting
     Collateral of such Grantor, execute and deliver any and all agreements,
     instruments, documents and papers as the Administrative Agent may
     reasonably request to such Grantor to evidence the Administrative Agent's
     and the Lenders' security interest in such Copyright, Patent or Trademark
     and the goodwill and general intangibles of such Grantor relating thereto
     or represented thereby;

          (iii)  pay or discharge taxes and Liens, other than Liens permitted
     under this Agreement or the other Credit Documents, levied or placed on the
     Collateral of such Grantor, effect any repairs or any insurance called for
     by the terms of this Agreement and pay all or any part of the premiums
     therefor and the costs thereof; and

          (iv)  (i) direct any party liable for any payment under any of the
     Collateral of such Grantor to make payment of any and all moneys due or to
     become due thereunder directly to the Administrative Agent or as the
     Administrative Agent shall direct; (ii) ask or demand for, collect, receive
     payment of and receipt for, any and all moneys, claims and other amounts
     due or to become due at any time in respect of or arising out of any
     Collateral of such Grantor; (iii) sign and indorse any invoices, freight or
     express bills, bills of lading, storage or warehouse receipts, drafts
     against debtors, assignments, verifications, notices and other documents in
     connection with any of the Collateral of such Grantor; (iv) commence and
     prosecute any suits, actions or proceedings at law or in equity in any
     court of competent jurisdiction to collect the Collateral of such Grantor
     or any portion thereof and to enforce any other right in respect of any
     Collateral of such Grantor; (v) defend any suit, action or proceeding
     brought against such Grantor with respect to any Collateral of such
     Grantor; (vi) settle, compromise or adjust any such suit, action or
     proceeding described in clause (v) above and, in connection therewith, to
     give such discharges or releases as the Administrative Agent may deem
     appropriate; (vii) subject to any existing reserved rights or licenses,
     assign any Copyright, Patent or Trademark constituting Collateral of such
     Grantor (along with the goodwill of the business to which any such
     Copyright, Patent or Trademark pertains), for such term or terms, on such
     conditions, and in such manner, as the Administrative Agent shall in its
     sole discretion determine; and (viii) generally, sell, transfer, pledge and
     make any agreement with respect to or otherwise deal with any of the
     Collateral of such Grantor as fully and completely as though the
     Administrative Agent were the absolute owner thereof for all purposes, and
     do, at the Administrative Agent's option and such Grantor's expense, at any
     time, or from time to time, all acts and things which the Administrative
     Agent deems necessary to protect, preserve or realize upon the Collateral
     of such Grantor and the Administrative Agent's and the other Secured
     Parties' security interests therein and to effect the intent of this
     Agreement, all as fully and effectively as such Grantor might do.

 
                                                                              30

     Anything in this Section 7.1(a) to the contrary notwithstanding, the
Administrative Agent agrees that it will not exercise any rights under the power
of attorney provided for in this Section 7.1(a) unless an Event of Default shall
have occurred and be continuing.

          (b)  The reasonable expenses of the Administrative Agent incurred in
connection with actions undertaken as provided in this Section 7.1, together
with interest thereon at a rate per annum equal to the rate per annum at which
interest would then be payable on past due ABR Loans that are Term Loans under
the Credit Agreement, from the date of payment by the Administrative Agent to
the date reimbursed by the relevant Granting Party, shall be payable by such
Granting Party to the Administrative Agent on demand.

          (c)  Each Granting Party hereby ratifies all that said attorneys shall
lawfully do or cause to be done by virtue hereof.  All powers, authorizations
and agencies contained in this Agreement are coupled with an interest and are
irrevocable as to the relevant Granting Party until this Agreement is terminated
as to such Granting Party, and the security interests in the Security Collateral
of such Granting Party created hereby are released.

          7.2  Duty of Administrative Agent.  The Administrative Agent's sole
               ----------------------------                                  
duty with respect to the custody, safekeeping and physical preservation of the
Security Collateral in its possession, under Section 9-207 of the Code or
otherwise, shall be to deal with it in the same manner as the Administrative
Agent deals with similar property for its own account.  Neither the
Administrative Agent, any other Secured Party nor any of their respective
officers, directors, employees or agents shall be liable for failure to demand,
collect or realize upon any of the Security Collateral or for any delay in doing
so or shall be under any obligation to sell or otherwise dispose of any Security
Collateral upon the request of any Granting Party or any other Person or, except
as otherwise provided herein, to take any other action whatsoever with regard to
the Security Collateral or any part thereof.  The powers conferred on the
Administrative Agent and the other Secured Parties hereunder are solely to
protect the Administrative Agent's and the other Secured Parties' interests in
the Security Collateral and shall not impose any duty upon the Administrative
Agent or any other Secured Party to exercise any such powers.  The
Administrative Agent and the other Secured Parties shall be accountable only for
amounts that they actually receive as a result of the exercise of such powers,
and neither they nor any of their officers, directors, employees or agents shall
be responsible to any Granting Party for any act or failure to act hereunder,
except as otherwise provided herein or for their own gross negligence or willful
misconduct.

          7.3  Execution of Financing Statements.  Pursuant to Section 9-402 of
               ---------------------------------                               
the Code and any other applicable law, each Granting Party authorizes the
Administrative Agent to file or record financing statements with respect to such
Granting Party's Security Collateral without the signature of such Granting
Party in such form and in such filing offices as the Administrative Agent
reasonably determines appropriate to perfect the security interests of the
Administrative Agent under this Agreement.  A photographic or other reproduction
of this Agreement shall be sufficient as a financing statement in any
jurisdiction.  The Administrative Agent agrees to notify the Grantor of any
financing or continuation statement filed by it pursuant to this Section 7.4,
provided that any failure to give such notice shall not affect the validity or
- --------                                                                      
effectiveness of any such filing.

 
                                                                              31

          7.4  Authority of Administrative Agent.  Each Granting Party
               ---------------------------------                      
acknowledges that the rights and responsibilities of the Administrative Agent
under this Agreement with respect to any action taken by the Administrative
Agent or the exercise or non-exercise by the Administrative Agent of any option,
voting right, request, judgment or other right or remedy provided for herein or
resulting or arising out of this Agreement or any amendment, supplement or other
modification of this Agreement shall, as between the Administrative Agent and
the Secured Parties, be governed by the Credit Agreement and by such other
agreements with respect thereto as may exist from time to time among them, but,
as between the Administrative Agent and the Granting Parties the Administrative
Agent shall be conclusively presumed to be acting as agent for the Secured
Parties with full and valid authority so to act or refrain from acting, and no
Granting Party shall be under any obligation, or entitlement, to make any
inquiry respecting such authority.

          7.5  Right Of Inspection.  Upon reasonable written advance notice to
               -------------------                                            
any Grantor and as often as may reasonably be desired, the Administrative Agent
shall have reasonable access during normal business hours to all the books,
correspondence and records of such Granting Party, and the Administrative Agent
and its representatives may examine the same, and to the extent reasonable, take
extracts therefrom and make photocopies thereof, and such Granting Party agrees
to render to the Administrative Agent, at such Granting Party's reasonable cost
and expense, such clerical and other assistance as may be reasonably requested
with regard thereto.  The Administrative Agent and its representatives shall
also have the right, upon reasonable advance written notice to such Granting
Party subject to any lease restrictions to enter during normal business hours
into and upon any premises owned, leased or operated by such Granting Party
where any of such Granting Party's Inventory or Equipment is located for the
purpose of inspecting the same, observing its use or otherwise protecting its
interests therein.


                           SECTION 8.  MISCELLANEOUS

          8.1  Amendments in Writing.  None of the terms or provisions of this
               ---------------------                                          
Agreement may be waived, amended, supplemented or otherwise modified except by a
written instrument executed by each affected Granting Party and the
Administrative Agent, provided that any provision of this Agreement imposing
                      --------                                              
obligations on any Granting Party may be waived by the Administrative Agent in a
written instrument executed by the Administrative Agent.

               -------                                                   
Administrative Agent or any Granting Party hereunder shall be effected in the
manner provided for in subsection 18.2 of the Credit Agreement; provided that
                                                                --------     
any such notice, request or demand to or upon any Guarantor shall be addressed
to such Guarantor at its notice address set forth on Schedule 1, unless and
                                                     ----------            
until such Guarantor shall change such address by notice to the Administrative
Agent given in accordance with subsection 18.2 of the Credit Agreement.

               ---------------------------------------------------              
Administrative Agent nor any other Secured Party shall by any act (except by a
written instrument pursuant to Section 8.1), delay, indulgence, omission or
otherwise be deemed to have waived any right or remedy hereunder or to have
acquiesced in any Default or Event of Default.  

 
                                                                              32

No failure to exercise, nor any delay in exercising, on the part of the
Administrative Agent or any other Secured Party, any right, power or privilege
hereunder shall operate as a waiver thereof. No single or partial exercise of
any right, power or privilege hereunder shall preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. A
waiver by the Administrative Agent or any other Secured Party of any right or
remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which the Administrative Agent or such other Secured Party would
otherwise have on any future occasion. The rights and remedies herein provided
are cumulative, may be exercised singly or concurrently and are not exclusive of
any other rights or remedies provided by law.

          8.4  Enforcement Expenses; Indemnification.  (a)  Each Guarantor

without limitation, the reasonable fees and disbursements of one firm of counsel
to the Secured Parties and the Administrative Agent.

          (b)  Each Guarantor agrees to pay, and to save the Administrative
Agent and the Secured Parties harmless from, (x) any and all liabilities with
respect to, or resulting from any delay in paying, any and all stamp, excise,
sales or other similar taxes which may be payable or determined to be payable
with respect to any of the Security Collateral or in connection with any of the
transactions contemplated by this Agreement and (y) any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever with respect to the
execution, delivery, enforcement, performance and administration of this
Agreement (collectively, the "indemnified liabilities"), in each case to the
                              -----------------------                       
extent the Borrower would be required to do so pursuant to subsection 18.5 of
the Credit Agreement, and in any event excluding any taxes or other indemnified
liabilities arising from gross negligence or willful misconduct of the
Administrative Agent or any Secured Party.

          (c)  The agreements in this Section 8.4 shall survive repayment of the
Obligations and all other amounts payable under the Credit Agreement and the
other Credit Documents.

          8.5  Successors and Assigns.  This Agreement shall be binding upon and
               ----------------------                                           
shall inure to the benefit of the Granting Parties, the Administrative Agent and
the Secured Parties and their respective successors and assigns; provided that
                                                                 --------     
no Granting Party may assign, transfer or delegate any of its rights or
obligations under this Agreement without the prior written consent of the
Administrative Agent.

          8.6  Set-Off.  Each Guarantor hereby irrevocably authorizes the
               -------                                                   
Administrative Agent and each other Secured Party at any time and from time to
time without notice to such Guarantor, any other Guarantor or the Borrower, any
such notice being expressly waived by each Guarantor and by the Borrower, to the
extent permitted by applicable law, upon the occurrence and during the
continuance of an Event of Default under subsection 16.2(a) or 16.3(a) of the
Credit Agreement so long as any amount remains unpaid after it becomes due and
payable by such Guarantor hereunder, to set-off and appropriate and apply
against any such amount any and 

 
                                                                              33

all deposits (general or special, time or demand, provisional or final) (other
than the Collateral Proceeds Account and the General Fund Account), in any
currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by the Administrative Agent or such other
Secured Party to or for the credit or the account of such Guarantor, or any part
thereof in such amounts as the Administrative Agent or such other Secured Party
may elect. The Administrative Agent and each other Secured Party shall notify
such Guarantor promptly of any such set-off and the application made by the
Administrative Agent or such other Secured Party of the proceeds thereof;
provided that the failure to give such notice shall not affect the validity of
- --------
such set-off and application. The rights of the Administrative Agent and each
other Secured Party under this Section 8.6 are in addition to other rights and
remedies (including, without limitation, other rights of set-off) which the
Administrative Agent or such other Secured Party may have.

          8.7  Counterparts.  This Agreement may be executed by one or more of
               ------------

prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction; provided that, with
                                                        --------           
respect to any Pledged Stock issued by a Foreign Subsidiary, all rights, powers
and remedies provided in this Agreement may be exercised only to the extent that
they do not violate any provision of any law, rule or regulation of any
Governmental Authority applicable to any such Pledged Stock or affecting the
legality, validity or enforceability of any of the provisions of this Agreement
against the Pledgor (such laws, rules or regulations, "Applicable Law") and are
                                                       --------------          
intended to be limited to extent necessary so that they will not render this
Agreement invalid, unenforceable or not entitled to be recorded, registered or
filed under the provisions of any Applicable Law.

          8.9  Section Headings.  The Section headings used in this Agreement
               ----------------
