time when each of its Receivables arises, the Pledgor shall be deemed to have
represented and warranted that such Receivable, and all records, papers and
documents relating thereto (if any) are genuine and in all material respects

the Collateral Agent so directs, the Pledgor shall legend, in form and manner
reasonably satisfactory to the Collateral Agent, its Receivables and the
Contracts, as well as all books, records and documents of the Pledgor evidencing
or pertaining to such Receivables and Contracts with an appropriate reference to
the fact that such Receivables and Contracts have been assigned to the

respect thereto as provided in preceding clause (x), and (z) that the Collateral
Agent may enforce collection of any such Receivables and Contracts and may
adjust, settle or compromise the amount of payment thereof, in the same manner

Pledgor, the Collateral Agent may apply any or all amounts then in, or
thereafter deposited in, the Cash Collateral Account which application shall be

reasonable costs and expenses (including reasonable attorneys' fees) of
collection, whether incurred by the Pledgor or the Collateral Agent, shall be

claim, suit or legal proceeding relating thereto, or sell any Receivable or
Contract, or interest therein, without the prior written consent of the
Collateral Agent (not to be unreasonably withheld), except as permitted by
Section 3.5.  Except as otherwise provided in the Credit Agreement, the Pledgor
will duly fulfill all obligations on its part to be fulfilled under or in
connection with the Receivables and Contracts and will do nothing to impair in
any material respect the rights of the Collateral Agent in the Receivables or
Contracts.

under any of its Contract, as and when due (including, without limitation,
amounts which are delinquent, such amounts to be collected in accordance with
generally accepted lawful collection procedures) any and all amounts owing under
or on account of such Receivable or Contract, and apply forthwith upon receipt
thereof all such amounts as are so collected to the outstanding balance of such
Receivable or under such Contract, except that, unless an Event of Default has
occurred and is continuing and the Collateral Agent has delivered notice to the
Pledgor in accordance with Article X of the Credit Agreement, the Pledgor may
allow in the ordinary course of business as adjustments to amounts owing under
its Receivables and Contracts (i) an extension or renewal of the time or times
of payment, or settlement for less than the total unpaid balance, as the Pledgor
finds appropriate in accordance with sound business judgment and (ii) a refund
or credit due as a result of returned or damaged merchandise or improperly

request by the Collateral Agent will promptly deliver such Instrument to the
Collateral Agent appropriately endorsed to the order of the Collateral Agent as
further security hereunder.

          Section 3.7.  Further Actions.  The Pledgor will, at its own expense,

reimburse the Collateral Agent for all reasonable costs and expenses of
procuring such insurance.  The Collateral Agent shall, at the time such proceeds
of such insurance are distributed to the Secured Creditors, apply such proceeds
in accordance with Section 7.4 or as otherwise provided in the Credit Agreement.

Collateral acquired by it and the liability of the Pledgor to pay the
Obligations shall in no way be affected or diminished by reason of the fact that
such Collateral may be lost, destroyed, stolen, damaged or for any reason
whatsoever unavailable to the Pledgor unless such loss or damage is finally
judicially determined to have been incurred by reason of the gross negligence or
willful misconduct of any Secured Creditor or any agent of any Secured Creditor
or the failure of a Secured Creditor, in exercising its remedies hereunder, to
act in a commercially reasonable manner.

          Section 6.2.  Warehouse Receipts Non-negotiable.  The Pledgor agrees
                        ---------------------------------                     
that if any warehouse receipt or receipt in the nature of a warehouse receipt is
issued with respect to any of its Inventory, such warehouse receipt or receipt
in the nature thereof shall not be "negotiable" (as such term is used in Section
7-104 of the Uniform Commercial Code as in effect in any relevant jurisdiction
or under other relevant law).

          Section 6.3.  Further Actions.  The Pledgor will, at its own expense,
                        ---------------                                        
make, execute, endorse, acknowledge, file and/or deliver to the Collateral Agent
from time to time such lists, descriptions and designations of its Collateral,
warehouse receipts, receipts in the nature of warehouse receipts, bills of
lading, documents of title, vouchers, invoices, schedules, confirmatory
assignments, conveyances, financing statements, transfer endorsements, powers of
attorney, certificates, reports and other assurances or instruments and take
such further steps relating to the Collateral and other property or rights
covered by the security interest hereby granted, which the Collateral Agent
deems reasonably appropriate or advisable to perfect, preserve or protect its
security interest in the Collateral in accordance with the terms hereof.

          Section 6.4.  Financing Statements.  The Pledgor agrees to execute and
                        --------------------                                    
deliver to the Collateral Agent such financing statements, in form reasonably
acceptable to the Collateral Agent, as the Collateral Agent may from time to
time reasonably request or as are necessary in the reasonable opinion of the
Collateral Agent to establish and maintain a valid, enforceable, first priority
perfected security interest in the Collateral as provided herein and the other
rights and security contemplated hereby all in accordance with the Uniform
Commercial Code as

enacted in any and all applicable jurisdictions or any other applicable law.
The Pledgor will pay any applicable filing fees, recordation taxes and related
expenses.  The Pledgor authorizes the Collateral Agent to file any such
financing statements without the signature of the Pledgor where permitted by
law.


                                  ARTICLE VII

                  REMEDIES UPON OCCURRENCE OF EVENT OF DEFAULT

          Section 7.1.  Remedies; Obtaining the Collateral Upon Default.  The
                        -----------------------------------------------      
Pledgor agrees that, if any Event of Default shall have occurred and be
continuing and the Collateral Agent shall have delivered to the Pledgor notice
in accordance with Article X of the Credit Agreement, then and in every such
case, subject to any mandatory requirements of applicable law then in effect,
the Collateral Agent, in addition to any rights now or hereafter existing under
applicable law, shall have all rights as a secured creditor under the Uniform
Commercial Code in all applicable jurisdictions and may also (subject to laws
and regulations governing the national security of the United States):

          (a) personally, or by agents or attorneys, immediately retake
     possession of the Collateral or any part thereof, from the Pledgor or any
     other Person who then has possession of any part thereof with or without
     notice or process of law, and for that purpose may enter upon the Pledgor's
     premises where any of the Collateral is located and remove the same and use
     in connection with such removal any and all services, supplies, aids and
     other facilities of the Pledgor; possession of machinery shall, however, be
     subject to the terms of the Location Leases; and

          (b) instruct the obligor or obligors on any agreement, instrument or
     other obligation (including, without limitation, the Receivables and the
     Contracts) constituting the Collateral to make any payment required by the
     terms of such agreement, instrument or other obligation directly to the
     Collateral Agent and may exercise any and all remedies of the Pledgor in
     respect of such Collateral; and

          (c)  withdraw all monies, securities and instruments in the Cash
     Collateral Account for application to the Obligations in accordance with
     Section 7.4; and

          (d)  sell, assign or otherwise liquidate, or direct the Pledgor to
     sell, assign or otherwise liquidate, any or all of its Collateral or any
     part thereof, and take possession of the proceeds of any such sale or
     liquidation; and
<PAGE>
 
                                                                         Page 16

     (e)  take possession of the Collateral or any part thereof, by directing
     the Pledgor in writing to deliver the same to the Collateral Agent at any
     commercially reasonable place or places designated by the Collateral Agent,
     in which event the Pledgor shall at its own expense:

               (i) forthwith cause the Collateral pledged by it to be moved to
          the place or places so designated by the Collateral Agent and there
          delivered to the Collateral Agent, and

              (ii) store and keep any Collateral so delivered to the Collateral
          Agent at such place or places pending further action by the Collateral
          Agent as provided in Section 7.2, and

             (iii)  while the Collateral shall be so stored and kept, provide
          such guards and maintenance services as shall be necessary to protect
          the same and to preserve and maintain them in good condition; and

          (f) license or sublicense (to the extent not in violation of the
     license), whether on an exclusive or nonexclusive basis, any Marks, Patents
     or Copyrights included in the Collateral for such term and on such
     conditions and in such manner as the Collateral Agent shall in its
     commercially reasonable judgment determine;

it being understood that the Pledgor's obligation so to deliver the Collateral
is of the essence of this Agreement and that, accordingly, upon application to a
court of equity having jurisdiction, the Collateral Agent shall be entitled to a
decree requiring specific performance by the Pledgor of said obligation.

          Section 7.2.  Remedies; Disposition of the Collateral.  Any Collateral
                        ---------------------------------------                 
repossessed by the Collateral Agent under or pursuant to Section 7.1 and any
other Collateral whether or not so repossessed by the Collateral Agent, may be
sold, assigned, leased or otherwise disposed of under one or more contracts or
as an entirety, and without the necessity of gathering at the place of sale the
property to be sold, and in general in such manner, at such time or times, at
such place or places and on such terms as the Collateral Agent may, in
compliance with any mandatory requirements of applicable law, determine;
provided that such terms shall be commercially reasonable.  Any of the
Collateral may be sold, leased or otherwise disposed of, in the condition in
which the same existed when taken by the Collateral Agent or after any
commercially reasonable overhaul or repair made by or at the direction of the
Collateral Agent.  Any such disposition which shall be a private sale or other
private proceedings permitted by
<PAGE>
 
                                                                         Page 17

such requirements shall be made upon not less than 10 days' written notice to
the Pledgor specifying the time at which such disposition is to be made and the
intended sale price or other consideration therefor, and shall be subject, for
the 10 days after the giving of such notice, to the right of the Pledgor or any
nominee of the Pledgor to acquire the Collateral involved at a price or for such
other consideration at least equal to the intended sale price or other
consideration so reasonably specified.  Any such disposition which shall be a
public sale permitted by such requirements shall be made upon not less than 10
days' written notice to the Pledgor specifying the time and place of such sale
and, in the absence of applicable requirements of law, shall be by public
auction (which may, at the Collateral Agent's option, be subject to reserve),
after publication of notice of such auction not less than 10 days prior thereto
in two newspapers in general circulation in the City of New York.  To the extent
permitted by any such requirement of law, the Collateral Agent and the Secured
Creditors may bid for and become the purchaser of the Collateral or any item
thereof, offered for sale in accordance with this Section without accountability
to the Pledgor.  If, under mandatory requirements of applicable law, the
Collateral Agent shall be required to make disposition of the Collateral within
a period of time which does not permit the giving of notice to the Pledgor as
hereinabove specified, the Collateral Agent need give the Pledgor only such
notice of disposition as shall be reasonably practicable in view of such
mandatory requirements of applicable law.  The Pledgor agrees to do or cause to
be done all such other acts and things as may be reasonably necessary to make
such sale or sales of all or any portion of the Collateral valid and binding and
in compliance with any and all applicable laws, regulations, orders, writs,
injunctions, decrees or awards of any and all courts, arbitrators or
governmental instrumentalities, domestic or foreign, having jurisdiction over
any such sale or sales, all at the Pledgor's reasonable expense.

          Section 7.3.  Waiver of Claims.  Except as otherwise provided in this
                        ----------------                                       
Agreement, THE PLEDGOR HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE LAW,
NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE COLLATERAL AGENT'S TAKING
POSSESSION OR THE COLLATERAL AGENT'S DISPOSITION OF ANY OF THE COLLATERAL,
INCLUDING, WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR ANY
PREJUDGMENT REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH PLEDGOR WOULD OTHERWISE
HAVE UNDER THE CONSTITUTION OR ANY STATUTE OF THE UNITED STATES OR OF ANY STATE,
and the Pledgor hereby further waives, to the extent permitted by law:

          (a) all damages occasioned by such taking of possession except any
     damages which are the direct result of the Collateral Agent's gross
     negligence or willful
<PAGE>
 
                                                                         Page 18

     misconduct or failure to act, in exercising its remedies hereunder, in a
     commercially reasonable manner;

          (b) all other requirements as to the time, place and terms of sale or
     other requirements with respect to the enforcement of the Collateral
     Agent's rights hereunder; and

          (c) all rights of redemption, appraisement, valuation, stay, extension
     or moratorium now or hereafter in force under any applicable law in order
     to prevent or delay the enforcement of this Agreement or the absolute sale
     of the Collateral or any portion thereof, and the Pledgor, for itself and
     all who may claim under it, insofar as it or they now or hereafter lawfully
     may, hereby waives the benefit of all such laws unless such action or
     threatened action is not commercially reasonable.

Any sale of, or the grant of options to purchase, or any other realization upon,
any Collateral shall operate to divest all right, title, interest, claim and
demand, either at law or in equity, of the Pledgor therein and thereto, and
shall be a perpetual bar both at law and in equity against the Pledgor and
against any and all Persons claiming or attempting to claim the Collateral so
sold, optioned or realized upon, or any part thereof, from, through and under
the Pledgor other than any Collateral remaining after payment in full of the
Obligations.

          Section 7.4.  Application of Proceeds.  (a)  All moneys collected by
                        -----------------------                               
the Collateral Agent (or, to the extent the Pledge Agreement or the Mortgage to
which the Pledgor is a party requires proceeds of Collateral under such
agreement to be applied in accordance with the provisions of this Agreement, the
Pledgee or Mortgagee under such other agreement) upon any sale or other
disposition of the Collateral, together with all other moneys received by the
Collateral Agent hereunder, shall be applied as follows:

          (i) first, to the payment of all amounts owing the Collateral Agent of
     the type described in clauses (iii) and (iv) of the definition of
     "Obligations";

         (ii) second, to the extent proceeds remain after the application
     pursuant to the preceding clause (i), an amount equal to the outstanding
     Primary Obligations shall be paid to the Secured Creditors as provided in
     Section 7.4(f), with each Secured Creditor receiving an amount equal to
     such outstanding Primary Obligations or, if the proceeds are insufficient
     to pay in full all such Primary Obligations, its Pro Rata Share of the
     amount remaining to be distributed;
<PAGE>
 
                                                                         Page 19

        (iii) third, to the extent proceeds remain after the application
     pursuant to the preceding clauses (i) and (ii), an amount equal to the
     outstanding Secondary Obligations shall be paid to the Secured Creditors as
     provided in Section 7.4(f), with each Secured Creditor receiving an amount
     equal to its outstanding Secondary Obligations or, if the proceeds are
     insufficient to pay in full all such Secondary Obligations, its Pro Rata
     Share of the amount remaining to be distributed; and

         (iv) fourth, to the extent proceeds remain after the application
     pursuant to the preceding clauses (i) through (iii), inclusive, and
     following the termination of this Agreement pursuant to Section 10.9(a)
     hereof, to the Pledgor or to whomever may be lawfully entitled to receive
     such surplus.

          (b) For purposes of this Agreement (x) "Pro Rata Share" shall mean,
when calculating a Secured Creditor's portion of any distribution or amount,
that amount (expressed as a percentage) equal to a fraction the numerator of
which is the then unpaid amount of such Secured Creditor's Primary Obligations
or Secondary Obligations, as the case may be, and the denominator of which is
the then outstanding amount of all Primary Obligations or Secondary Obligations,
as the case may be, (y) "Primary Obligations" shall mean (i) in the case of the
Credit Agreement Obligations, all principal of, and interest on, all Loans, all
Unpaid Drawings theretofore made (together with all interest accrued thereon),
and the aggregate Stated Amounts of all Letters of Credit issued (or deemed
issued) under the Credit Agreement, and all Fees and (ii) in the case of the
Other Obligations, all amounts due under the Interest Rate Protection or Other
Hedging Agreements (other than indemnities, fees (including, without limitation,
reasonable attorneys' fees) and similar obligations and liabilities) and (z)
"Secondary Obligations" shall mean all Obligations other than Primary
Obligations.

          (c) When payments to Secured Creditors are based upon their respective
Pro Rata Shares, the amounts received by such Secured Creditors hereunder shall
be applied (for purposes of making determinations under this Section 7.4 only)
(i) first, to their Primary Obligations and (ii) second, to their Secondary
Obligations.  If any payment to any Secured Creditor of its Pro Rata Share of
any distribution would result in overpayment to such Secured Creditor, such
excess amount shall instead be immediately distributed in respect of the unpaid
Primary Obligations or Secondary Obligations, as the case may be, of the other
Secured Creditors, with each Secured Creditor whose Primary Obligations or
Secondary Obligations, as the case may be, have
<PAGE>
 
                                                                         Page 20

not been paid in full to receive an amount equal to such excess amount
multiplied by a fraction the numerator of which is the unpaid Primary
Obligations or Secondary Obligations, as the case may be, of such Secured
Creditor and the denominator of which is the unpaid Primary Obligations or
Secondary Obligations, as the case may be, of all Secured Creditors entitled to
such distribution.

          (d) Each of the Secured Creditors agrees and acknowledges that if the
Bank Creditors are to receive a distribution on account of undrawn amounts with
respect to Letters of Credit issued (or deemed issued) under the Credit
Agreement (which shall only occur after all outstanding Loans and Unpaid
Drawings with respect to such Letters of Credit have been paid in full), such
amounts shall be paid to the Administrative Agent under the Credit Agreement and
held by it, for the equal and ratable benefit of the Bank Creditors, as cash
security for the repayment of Obligations owing to the Bank Creditors as such.
If any amounts are held as cash security pursuant to the immediately preceding
sentence, then upon the termination of all outstanding Letters of Credit, and
after the application of all such cash security to the repayment of all
Obligations owing to the Bank Creditors after giving effect to the termination
of all such Letters of Credit, if there remains any excess cash, such excess
cash shall be distributed by the Collateral Agent in accordance with Section
7.4(a) hereof.

          (e) Except as set forth in Section 7.4(d), all payments required to be
made hereunder shall be made (x) if to the Bank Creditors, to the Administrative
Agent under the Credit Agreement for the account of the Bank Creditors, and (y)
if to the Other Creditors, to the trustee, paying agent or other similar
representative (each a "Representative") for the Other Creditors or, in the
absence of such a Representative, directly to the Other Creditors.

          (f) For purposes of applying payments received in accordance with this
Section 7.4, the Collateral Agent shall be entitled to rely upon (i) the
Administrative Agent under the Credit Agreement and (ii) the Representative for
the Other Creditors or, in the absence of such a Representative, upon the Other
Creditors for a determination (which the Administrative Agent, each
Representative for any Secured Creditors and the Secured Creditors agree (or
shall agree) to provide upon request of the Collateral Agent) of the outstanding
Primary Obligations and Secondary Obligations owed to the Bank Creditors or the
Other Creditors, as the case may be.  Unless it has actual knowledge (including
by way of written notice from a Bank Creditor or an Other Creditor) to the
contrary, the Administrative Agent and each Representative, in furnishing
information pursuant to the
<PAGE>
 
                                                                         Page 21

preceding sentence, and the Collateral Agent, in acting hereunder, shall be
entitled to assume that no Secondary Obligations are outstanding.  Unless it has
actual knowledge (including by way of written notice from an Other Creditor) to
the contrary, the Collateral Agent, in acting hereunder, shall be entitled to
assume that no Interest Rate Protection or Other Hedging Agreements are in
existence.

          (g) It is understood and agreed that the Pledgor shall remain liable
to the extent of any deficiency between the amount of the proceeds of the
Collateral hereunder and the aggregate amount of the sums referred to in clauses
(i) through (iii), inclusive, of Section 7.4(a), except to the extent that such
proceeds are not applied by the Collateral Agent in accordance with this
Agreement and the Credit Agreement.

          Section 7.5.  Remedies Cumulative.  Each and every right, power and
                        -------------------                                  
remedy hereby specifically given to the Collateral Agent shall be in addition to
every other right, power and remedy specifically given under this Agreement, the
Interest Rate Protection or Other Hedging Agreements, the other Credit Documents
or now or hereafter existing at law or in equity, or by statute and each and
every right, power and remedy whether specifically herein given or otherwise
existing may be exercised from time to time or simultaneously and as often and
in such order as may be deemed expedient by the Collateral Agent.  All such
rights, powers and remedies shall be cumulative and the exercise or the
beginning of exercise of one shall not be deemed a waiver of the right to
exercise of any other or others.  No delay or omission of the Collateral Agent
in the exercise of any such right, power or remedy, renewal or extension of any
of the Obligations and no course of dealing between the Pledgor and the
Collateral Agent or any holder of any of the Obligations shall impair any such
right, power or remedy or shall be construed to be a waiver of any Default or
Event of Default or an acquiescence therein.  No notice to or demand on the
Pledgor in any case shall entitle it to any other or further notice or demand in
similar or other circumstances or constitute a waiver of any of the rights of
the Collateral Agent to any other or further action in any circumstances without
notice or demand.  In the event that the Collateral Agent shall bring any suit
to enforce any of its rights hereunder and shall be entitled to judgment, then
in such suit the Collateral Agent may recover expenses, including reasonable
attorneys' fees, and the amounts thereof shall be included in such judgment.

          Section 7.6.  Discontinuance of Proceedings.  In case the Collateral
                        -----------------------------                         
Agent shall have instituted any proceeding to enforce any right, power or remedy
under this Agreement by foreclosure, sale, entry or otherwise, and such
proceeding shall

                                                                         Page 22

have been discontinued or abandoned for any reason or shall have been determined
adversely to the Collateral Agent, then and in every such case the Pledgor, the
Collateral Agent and each holder of any of the Obligations shall be restored to
their former positions and rights hereunder with respect to the Collateral
subject to the security interest created under this Agreement, and all rights,
remedies and powers of the Collateral Agent shall continue as if no such
proceeding had been instituted.


                                  ARTICLE VIII

                                   INDEMNITY

          Section 8.1.  Indemnity.  (a)  The Pledgor agrees to indemnify,
                        ---------                                        
reimburse and hold the Collateral Agent, each Secured Creditor and their
respective successors, assigns, employees, agents and servants (hereinafter in
this Section 8.1 referred to individually as "Indemnitee," and collectively as
"Indemnities") harmless from any and all liabilities, obligations, damages,
injuries, penalties, claims, demands, actions, suits, judgments and any and all
costs, expenses or disbursements (including reasonable attorneys' fees and
expenses) (for the purposes of this Section 8.1 the foregoing are collectively
called "expenses") of whatsoever kind and nature imposed on, asserted against or
incurred by any of the Indemnities arising out of this Agreement, [any Interest
Rate Protection or Other Hedging Agreement,] any other Credit Document or any
other document executed in connection herewith and therewith or in any other way
connected with the administration of the transactions contemplated hereby and
thereby or the enforcement of any of the terms of, or the preservation of any
rights under any thereof, or in any way relating to or arising out of the
manufacture, ownership, ordering, purchase, delivery, control, acceptance,
lease, financing, possession, operation, condition, sale, return or other
disposition, or use of the Collateral (including, without limitation, latent or
other defects, whether or not discoverable), any contract claim or, to the
maximum extent permitted under applicable law, the violation of the laws of any
country, state or other governmental body or unit, or any tort (including,
without limitation, claims arising or imposed under the doctrine of strict
liability, or for or on account of injury to or the death of any Person
(including any Indemnitee), or property damage); provided that no Indemnitee
shall be indemnified pursuant to this Section 8.1(a) for expenses to the extent
finally judicially determined to have been incurred by reason of the gross
negligence or willful misconduct of such Indemnitee.  The Pledgor agrees that
upon written notice by any Indemnitee of the assertion of such a liability,
obligation, damage, injury, penalty, claim, demand, action, suit or judgment,
the Pledgor
<PAGE>
 
                                                                         Page 23

shall assume full responsibility for the defense thereof.  Each Indemnitee
agrees to use its best efforts to promptly notify the Pledgor of any such
assertion of which such Indemnitee has knowledge.

          (b) Without limiting the application of Section 8.1(a), the Pledgor
agrees to pay, or reimburse the Collateral Agent for any and all reasonable
fees, costs and expenses of whatever kind or nature incurred in connection with
the creation, preservation or protection of the Collateral Agent's Liens on, and
security interest in, the Collateral, including, without limitation, all
reasonable fees and taxes in connection with the recording or filing of
instruments and documents in public offices, payment or discharge of any taxes
or Liens upon or in respect of the Collateral, premiums for insurance with
respect to the Collateral and all other fees, costs and expenses in connection
with protecting, maintaining or preserving the Collateral and the Collateral
Agent's interest therein, whether through judicial proceedings or otherwise, or
in defending or prosecuting any actions, suits or proceedings arising out of or
relating to the Collateral as set forth herein and in the Credit Agreement.

          (c) Without limiting the application of Section 8.1(a) or (b), the
Pledgor agrees to pay, indemnify and hold each Indemnitee harmless from and
against any loss, costs, damages and expenses which such Indemnitee may suffer,
expend or incur in consequence of or growing out of any material
misrepresentation by the Pledgor in this Agreement, any Interest Rate Protection
or Other Hedging Agreement, any other Credit Document or in any writing
contemplated by or made or delivered pursuant to or in connection with this
Agreement, any Interest Rate Protection or Other Hedging Agreement or any other
Credit Document as set forth herein and in the Credit Agreement.

          (d) If and to the extent that the obligations of the Pledgor under
this Section 8.1 are unenforceable for any reason, the Pledgor hereby agrees to
make the maximum contribution to the payment and satisfaction of such
obligations which is permissible under applicable law.

          Section 8.2.  Indemnity Obligations Secured by Collateral; Survival.
                        -----------------------------------------------------  
Any amounts paid by any Indemnitee as to which such Indemnitee has the right to
reimbursement shall constitute Obligations secured by the Collateral.  The
indemnification obligations of the Pledgor contained in this Article VIII shall
continue in full force and effect notwithstanding the full payment of all the
Notes issued under the Credit Agreement, the termination of all Interest Rate
Protection or Other Hedging Agreements and the payment of all other Obligations
and notwithstanding the discharge thereof.

          The following terms shall have the meanings herein specified.  Such
definitions shall be equally applicable to the singular and plural forms of the
terms defined.
