unconditionally and irrevocably, guarantees to the Administrative Agent, for the
ratable benefit of the Lenders and their respective successors, indorsees,
transferees and assigns, the prompt and complete payment and performance by the
Borrower when due (whether at the stated maturity, by acceleration or otherwise)
of the Borrower Obligations.

     (b)    Anything herein or in any other Loan Document to the contrary
notwithstanding, the maximum liability of each Guarantor hereunder and under the
other Loan Documents shall in no event exceed the amount which can be guaranteed
by such Guarantor under applicable federal and state laws relating to the
insolvency of debtors (after giving effect to the right of contribution
established in Section 2.2).

<Page>

     (c)    Each Guarantor agrees that the Borrower Obligations may at any time
and from time to time exceed the amount of the liability of such Guarantor
hereunder without impairing the guarantee contained in this Section 2 or
affecting the rights and remedies of the Administrative Agent or any Lender
hereunder.

     (d)    The guarantee contained in this Section 2 shall remain in full force
and effect until all the Borrower Obligations and the obligations of each
Guarantor under the guarantee contained in this Section 2 shall have been
satisfied by payment in full, no Letter of Credit shall be outstanding and the
Commitments shall be terminated, notwithstanding that from time to time during
the term of the Credit Agreement the Borrower may be free from any Borrower
Obligations.

     (e)    No payment made by the Borrower, any of the Guarantors, any other
guarantor or any other Person or received or collected by the Administrative
Agent or any Lender from the Borrower, any of the Guarantors, any other
guarantor or any other Person by virtue of any action or proceeding or any
set-off or appropriation or application at any time or from time to time in
reduction of or in payment of the Borrower Obligations shall be deemed to
modify, reduce, release or otherwise affect the liability of any Guarantor
hereunder which shall, notwithstanding any such payment (other than any payment
made by such Guarantor in respect of the Borrower Obligations or any payment
received or collected from such Guarantor in respect of the Borrower
Obligations), remain liable for the Borrower Obligations up to the maximum
liability of such Guarantor hereunder until the Borrower Obligations are paid in
full, no Letter of Credit shall be outstanding and the Commitments are
terminated.

     2.2    RIGHT OF CONTRIBUTION. Each Subsidiary Guarantor hereby agrees that
to the extent that a Subsidiary Guarantor shall have paid more than its
proportionate share of any payment made hereunder, such Subsidiary Guarantor
shall be entitled to seek and receive contribution from and against any other
Subsidiary Guarantor hereunder which has not paid its proportionate share of
such payment. Each Subsidiary Guarantor's right of contribution shall be subject
to the terms and conditions of Section 2.3. The provisions of this Section 2.2
shall in no respect limit the obligations and liabilities of any Subsidiary
Guarantor to the Administrative Agent and the Lenders, and each Subsidiary
Guarantor shall remain liable to the Administrative Agent and the Lenders for
the full amount guaranteed by such Subsidiary Guarantor hereunder.

     2.3    NO SUBROGATION. Notwithstanding any payment made by any Guarantor
hereunder or any set-off or application of funds of any Guarantor by the
Administrative Agent or any Lender, no Guarantor shall be entitled to be
subrogated to any of the rights of the Administrative Agent or any Lender
against the Borrower or any other Guarantor or any collateral security or
guarantee or right of offset held by the Administrative Agent or any Lender for
the payment of the Borrower Obligations, nor shall any Guarantor seek or be
entitled to seek any contribution or reimbursement from the Borrower or any
other Guarantor in respect of payments made by such Guarantor hereunder, until
all amounts owing to the Administrative Agent and the Lenders by the Borrower on
account of the Borrower Obligations are paid in full (other than contingent
obligations and liabilities), no Letter of Credit shall be outstanding and the
Commitments are terminated. If any amount shall be paid to any Guarantor on
account of such subrogation rights at any time when all of the Borrower
Obligations shall not have been paid in full, such amount shall be held by such
Guarantor in trust for the Administrative Agent and the Lenders, segregated from
other funds of such Guarantor, and shall, forthwith upon receipt by such
Guarantor, be turned over to the Administrative Agent in the exact form received
by such Guarantor (duly indorsed by such Guarantor to the Administrative Agent,
if required), to be applied against the Borrower Obligations, whether matured or
unmatured, in such order as the Administrative Agent may determine, subject to
the terms of the Loan Documents.

<Page>

     2.4    AMENDMENTS, ETC. WITH RESPECT TO THE BORROWER OBLIGATIONS. Each
Guarantor shall remain obligated hereunder notwithstanding that, without any
reservation of rights against any Guarantor and without notice to or further
assent by any Guarantor, any demand for payment of any of the Borrower
Obligations made by the Administrative Agent or any Lender may be rescinded by
the Administrative Agent or such Lender and any of the Borrower Obligations
continued, and the Borrower Obligations, or the liability of any other Person
upon or for any part thereof, or any collateral security or guarantee therefor
or right of offset with respect thereto, may, from time to time, in whole or in
part, be renewed, extended, amended, modified, accelerated, compromised, waived,
surrendered or released by the Administrative Agent or any Lender, and the
Credit Agreement and the other Loan Documents and any other documents executed
and delivered in connection therewith may be amended, modified, supplemented or
terminated, in whole or in part, as the Administrative Agent (or the Required
Lenders or all Lenders, as the case may be) may deem advisable from time to
time, subject to the terms of the Loan Documents, and any collateral security,
guarantee or right of offset at any time held by the Administrative Agent or any
Lender for the payment of the Borrower Obligations may be sold, exchanged,
waived, surrendered or released. Neither the Administrative Agent nor any Lender
shall have any obligation to protect, secure, perfect or insure any Lien at any
time held by it as security for the Borrower Obligations or for the guarantee
contained in this Section 2 or any property subject thereto.

     2.5    GUARANTEE ABSOLUTE AND UNCONDITIONAL. Each Guarantor waives any and
all notice of the creation, renewal, extension or accrual of any of the Borrower
Obligations and notice of or proof of reliance by the Administrative Agent or
any Lender upon the guarantee contained in this Section 2 or acceptance of the
guarantee contained in this Section 2; the Borrower Obligations, and any of
them, shall conclusively be deemed to have been created, contracted or incurred,
or renewed, extended, amended or waived, in reliance upon the guarantee
contained in this Section 2; and all dealings between the Borrower and any of
the Guarantors, on the one hand, and the Administrative Agent and the Lenders,
on the other hand, likewise shall be conclusively presumed to have been had or
consummated in reliance upon the guarantee contained in this Section 2. To the
extent permitted by applicable law, each Guarantor waives diligence,
presentment, protest, demand for payment and notice of default or nonpayment to
or upon the Borrower or any of the Guarantors with respect to the Borrower
Obligations. Each Guarantor understands and agrees that the guarantee contained
in this Section 2 shall be construed as a continuing, absolute and unconditional
guarantee of payment without regard to (a) the validity or enforceability of the
Credit Agreement or any other Loan Document, any of the Borrower Obligations or
any other collateral security therefor or guarantee or right of offset with
respect thereto at any time or from time to time held by the Administrative
Agent or any Lender, (b) any defense, set-off or counterclaim (other than a
defense of payment or performance) which may at any time be available to or be
asserted by the Borrower or any other Person against the Administrative Agent or
any Lender, or (c) any other circumstance whatsoever (with or without notice to
or knowledge of the Borrower or such Guarantor) which 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 Lender 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 Lender to make any such demand, to pursue such other
rights or remedies or to collect any payments from the Borrower, any other
Guarantor or any other 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 right of offset, shall not relieve any Guarantor of any
obligation or liability hereunder, and shall not impair or affect the rights and
remedies, whether express, implied or available as a matter of law, of the
Administrative Agent or any

Lender against any Guarantor. For the purposes hereof "demand" shall include the
commencement and continuance of any legal proceedings.

     2.6    REINSTATEMENT. The guarantee contained in this Section 2 shall
continue to be effective, or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any of the Borrower Obligations is rescinded or
must otherwise be restored or returned by the Administrative Agent or any Lender
upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of
the Borrower or any Guarantor, or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for, the
Borrower or any Guarantor or any substantial part of its property, or otherwise,
all as though such payments had not been made.

     2.7    PAYMENTS. Each Guarantor hereby guarantees that payments hereunder
will be paid to the Administrative Agent without set-off or counterclaim in
Dollars at the Funding Office.

                      SECTION 3. GRANT OF SECURITY INTEREST

            Each Grantor hereby assigns and transfers to the Administrative

all of the following property now owned or at any time hereafter acquired by
such Grantor or in which such Grantor now has or at any time in the future may
acquire any right, title or interest (collectively, the "COLLATERAL"), as

security and guarantees given by any Person with respect to any of the
foregoing;

            PROVIDED, HOWEVER, that notwithstanding any of the other provisions
set forth in this Section 3, this Agreement shall not constitute a grant of a
security interest in any property to the extent that (x) such grant of a
security interest is prohibited by any Requirements of Law of a Governmental
Authority, requires a consent not obtained of any Governmental Authority
pursuant to such Requirement of Law or is prohibited by, or constitutes a breach
or default under or results in the termination of or requires any consent not
obtained under, any contract, license, agreement, instrument or other document
evidencing or giving rise to such property or, in the case of any Investment
Property, Pledged Stock or Pledged Note, any applicable shareholder or similar
agreement, except to the extent that such Requirement of Law or the term in such
contract, license, agreement, instrument or other document or shareholder or
similar agreement providing for such prohibition, breach, default or termination
or requiring such consent is ineffective under applicable law or (y) such
property is subject to a Lien permitted by Section 7.3(f), (g) or (l) of the
Credit Agreement, and with respect to such property the Administrative Agent and
the Lenders are not permitted to obtain a second priority Lien by the terms

shall extend to the Proceeds of any property described in this paragraph to the
extent that such Proceeds are not subject to either clause (x) or clause (y),
and if such Proceeds are subject to either clause (x) or clause (y), then this
Agreement shall not constitute a grant of a security interest in any such
Proceeds.

                    SECTION 4. REPRESENTATIONS AND WARRANTIES

            To induce the Administrative Agent and the Lenders to enter into the
Credit Agreement and to induce the Lenders to make their respective extensions
of credit to the Borrower thereunder, each Grantor hereby represents and
warrants to the Administrative Agent and each Lender that:

     4.1    NO OTHER LIENS. No financing statement or other public notice with
respect to all or any part of the Collateral is on file or of record in any
public office, except such as have been filed in favor of the Administrative
Agent, for the ratable benefit of the Lenders, pursuant to this Agreement or as
are permitted by the Credit Agreement.

     4.2    PERFECTED FIRST PRIORITY LIENS. The security interests granted
pursuant to this Agreement (a) upon completion of the filings and other actions
specified on SCHEDULE 3 (which, in the case of all filings and other documents
referred to on said Schedule, have been delivered to the Administrative Agent in
completed and duly executed form) will constitute valid perfected security
interests in all of the Collateral in favor of the Administrative Agent, for the
ratable benefit of the Lenders, as collateral security for such Grantor's
Obligations, enforceable in accordance with the terms hereof against all
creditors of such Grantor and any Persons purporting to purchase any Collateral
from such Grantor and (b) are prior to all other Liens on the Collateral in
existence on the date hereof except for Liens permitted by the Credit Agreement
which have priority over the Liens on the Collateral by operation of law.

hereof, such Grantor's jurisdiction of organization, identification number from
the jurisdiction of organization (if any), and the location of such Grantor's

     (b)    All the shares of the Pledged Stock have been duly and validly
issued and are fully paid and nonassessable.

     (c)    To the best of such Grantor's knowledge, each of the Pledged Notes
constitutes the legal, valid and binding obligation of the obligor with respect
thereto, enforceable in accordance with its terms, subject to the effects of
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
other similar laws relating to or affecting creditors' rights generally, general
equitable principles (whether considered in a proceeding in equity or at law)
and an implied covenant of good faith and fair dealing.

     (d)    Such Grantor is the record and beneficial owner of, and has good and
marketable title to, the Investment Property pledged by it hereunder, free of

permitted by the Credit Agreement.

     4.7    RECEIVABLES. (a) No amount in excess of $100,000 payable to such
Grantor under or in connection with any Receivable is evidenced by any
Instrument or Chattel Paper which has not been delivered to the Administrative
Agent.

     (b)    Except with respect to Receivables payable by Medicaid and Medicare,
none of the obligors on any Receivables is a Governmental Authority.

be accurate in all material respects.

     4.8    CONTRACTS. (a)  Except for the failure of which could not
reasonably be expected to have a Material Adverse Effect, each Contract is in
full force and effect and constitutes a valid and legally enforceable obligation
of the parties thereto, subject to the effects of bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium and other similar laws
relating to or affecting creditors' rights generally, general equitable
principles (whether considered in a proceeding in equity or at law) and an
implied covenant of good faith and fair dealing.

     (b)    Neither such Grantor nor (to the best of such Grantor's knowledge)
any of the other parties to the Contracts is in default in the performance or
observance of any of the terms thereof in any manner that, in the aggregate,
could reasonably be expected to have a Material Adverse Effect.

     (c)    Such Grantor has made available to the Administrative Agent a
complete and correct copy of each Contract, including all amendments,
supplements and other modifications thereto.

     (d)    No amount in excess of $100,000 payable to such Grantor under or in

            Each Grantor covenants and agrees with the Administrative Agent and
the Lenders that, from and after the date of this Agreement until the
Obligations (other than contingent obligations and liabilities) shall have been
paid in full, no Letter of Credit shall be outstanding and the Commitments shall
have terminated:

     5.1    DELIVERY OF INSTRUMENTS, CERTIFICATED SECURITIES AND CHATTEL PAPER.
If any amount in excess of $100,000 payable under or in connection with any of
the Collateral shall be or become evidenced by any Instrument, Certificated
Security or Chattel Paper, such Instrument, Certificated Security or Chattel
Paper shall be promptly delivered to the Administrative Agent, duly indorsed in
a manner satisfactory to the Administrative Agent, to be held as Collateral
pursuant to this Agreement.

     5.2    MAINTENANCE OF PERFECTED SECURITY INTEREST; FURTHER DOCUMENTATION.
(a) Such Grantor shall maintain the security interest created by this Agreement
as a perfected security interest having at least the priority described in
Section 4.2 and shall use commercially reasonable efforts to defend such
security interest against any material claims and demands of all Persons
whomsoever (other than Persons claiming by, through or under the Administrative
Agent), subject to the rights of such Grantor under the Loan Documents to
dispose of the Collateral.

     (b)    As soon as practicable following the request of the Administrative
Agent, such Grantor will furnish to the Administrative Agent and the Lenders
statements and schedules further identifying and describing the assets and
property of such Grantor and such other reports in connection therewith as the
Administrative Agent may reasonably request, all in reasonable detail.

     (c)    At any time and from time to time, upon the written request of the
Administrative Agent, and at the sole expense of such Grantor, such Grantor will
promptly and duly execute and deliver, and have recorded, such further
instruments and documents and take such further actions as the Administrative
Agent may reasonably request for the purpose of obtaining or preserving the full
benefits of this Agreement and of the rights and powers herein granted,
including, without limitation, (i) filing any financing or continuation
statements under the Uniform Commercial Code (or other similar laws) in effect
in any jurisdiction with respect to the security interests created hereby and
(ii) in the case of Investment Property, Deposit Accounts, Letter-of-Credit
Rights and any other relevant Collateral, taking any actions reasonably
necessary to enable the Administrative Agent to obtain "control" (within the
meaning of the applicable Uniform Commercial Code) with respect thereto.

     5.3    INVESTMENT PROPERTY. (a) If such Grantor shall become entitled to
receive or shall receive any certificate (including, without limitation, any
certificate representing a dividend or a distribution in connection with any
reclassification, increase or reduction of capital or any certificate issued in
connection with any reorganization), option or rights in respect of the Capital
Stock of any Issuer, whether in addition to, in substitution of, as a conversion
of, or in exchange for, any shares of the Pledged

<Page>

Stock, or otherwise in respect thereof, such Grantor shall accept the same as
the agent of the Administrative Agent and the Lenders, hold the same in trust
for the Administrative Agent and the Lenders and deliver the same forthwith to
the Administrative Agent in the exact form received, duly indorsed by such
Grantor to the Administrative Agent, if required, together with an undated stock
power covering such certificate duly executed in blank by such Grantor and with,
if the Administrative Agent so reasonably requests, signature guaranteed, to be
held by the Administrative Agent, subject to the terms hereof, as additional
collateral security for the Obligations. Any sums paid upon or in respect of the
Investment Property (other than Cash Equivalents) upon the liquidation or
dissolution of any Issuer (other than, so long as no Event of Default shall have
occurred and be continuing, with respect to a dissolution or liquidation
permitted by Section 7.4(e) of 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 respect of the Investment Property or any property shall be
distributed upon or with respect to the Investment Property pursuant to the
recapitalization or reclassification of the capital of any Issuer or pursuant to
the reorganization thereof, the property so distributed shall, unless otherwise
subject to a perfected security interest in favor of the Administrative Agent,
be delivered to the Administrative Agent to be held by it hereunder as
additional collateral security for the Obligations. If any sums of money or
property so paid or distributed in respect of the Investment Property shall be
received by such Grantor, such Grantor shall, until such money or property is
paid or delivered to the Administrative Agent, hold such money or property in
trust for the Administrative Agent and the Lenders, segregated from other funds
of such Grantor, as additional collateral security for the Obligations.

     (b)    Without the prior written consent of the Administrative Agent, such
Grantor will not (i) vote to enable, or take any other action to permit, any
Issuer to issue (except to such Grantor or another Grantor) any Capital Stock of
any nature or to issue (except to such Grantor or another Grantor) any other
securities convertible into or granting the right to purchase or exchange for
any Capital Stock of any nature of any Issuer, (ii) sell, assign, transfer,
exchange, or otherwise dispose of, or grant any option with respect to, the
Investment Property or Proceeds thereof (except pursuant to a transaction
expressly permitted by the Credit Agreement), (iii) create, incur or permit to
exist any Lien or option in favor of, or any claim of any Person with respect
to, any of the Investment Property or Proceeds thereof, or any interest therein,
except for the security interests created by this Agreement or Liens permitted
under the Credit Agreement or (iv) enter into any agreement or undertaking
restricting the right or ability of such Grantor or the Administrative Agent to
sell, assign or transfer any of the Investment Property or Proceeds thereof.

     (c)    In the case of each Grantor which is an Issuer, such Issuer agrees
that (i) it will be bound by the terms of this Agreement relating to the
Investment Property issued by it and will comply with such terms insofar as such
terms are applicable to it, (ii) it will notify the Administrative Agent
promptly in writing of the occurrence of any of the events described in Section
5.7(a) with respect to the Investment Property issued by it and (iii) the terms
of Sections 6.3(c) and 6.7 shall apply to it, MUTATIS MUTANDIS, with respect to
all actions that may be required of it pursuant to Section 6.3(c) or 6.7 with
respect to the Investment Property issued by it.

     5.4    CONTRACTS. (a) Such Grantor will perform and comply in all respects
with all its obligations under the Contracts except to the extent that failure
to do so could not, in the aggregate, reasonably be expected to have a Material
Adverse Effect.

     (b)    Except as could not reasonably be expected to have a Material
Adverse Effect, such Grantor will not amend, modify, terminate or waive any
provision of any Contract in any manner which could reasonably be expected to
materially adversely affect the value of such Contract as Collateral.

<Page>

     (c)    Such Grantor will exercise promptly and diligently each and every
right which it may have under each Contract (other than any right of
termination) except to the extent that failure to do so could not, in the
aggregate, reasonably be expected to have a Material Adverse Effect.

                         SECTION 6. REMEDIAL PROVISIONS

     6.1    CERTAIN MATTERS RELATING TO RECEIVABLES. (a) The Administrative
Agent shall have the right to make test verifications of the Receivables in any
reasonable manner and through any reasonable medium (after consultation with the
Borrower), and each Grantor shall furnish all such assistance and information as
the Administrative Agent may require in connection with such test verifications.
At any time and from time to time, upon the Administrative Agent's request
(which request shall be limited to one request per Grantor each fiscal year,
unless otherwise consented to by the relevant Grantor (such consent not to be
unreasonably withheld or delayed); PROVIDED that if an Event of Default has
occurred and is continuing, such limitation on the Administrative Agent's
ability to make such request shall not be applicable) and at the expense of the
relevant Grantor, such Grantor shall cause independent public accountants or
others satisfactory to the Administrative Agent to furnish to the Administrative
Agent reports showing reconciliations, aging and test verifications of, and
trial balances for, the Receivables.

     (b)    The Administrative Agent hereby authorizes each Grantor to collect
such Grantor's Receivables, subject to the Administrative Agent's direction and
control, 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 payments of Receivables, when
collected by any Grantor, (i) shall be forthwith (and, in any event, within two
Business Days) deposited by such Grantor in the exact form received, duly
indorsed by such Grantor to the Administrative Agent if required, in a
Collateral Account maintained under the sole dominion and control of the
Administrative Agent, subject to withdrawal by the Administrative Agent for the
account of the Lenders only as provided in Section 6.5, and (ii) until so turned
over, shall be held by such Grantor in trust for the Administrative Agent and
the Lenders, segregated from other funds of such Grantor. Each such deposit of
Proceeds of Receivables shall be accompanied by a report identifying in
reasonable detail the nature and source of the payments included in the deposit.

     (c)    At the Administrative Agent's reasonable request, each Grantor shall
deliver to the Administrative Agent copies of all documents evidencing, and
relating to, the agreements and transactions which gave rise to the Receivables,
including, without limitation, copies of all orders, invoices and shipping
receipts. Originals of such documents shall be provided if necessary, in the
reasonable discretion of the Administrative Agent, upon the request of the
Administrative Agent.

     6.2    COMMUNICATIONS WITH OBLIGORS; GRANTORS REMAIN LIABLE. (a) At such
time as the Consolidated Senior Leverage Ratio exceeds 2.25 or an Event of
Default has occurred and is continuing, the Administrative Agent, in the name of
the Borrower or any Loan Party or, if an Event of Default has occurred and is
continuing, in its own name or in the name of others, may, to the extent
reasonably necessary and after written notice to the Borrower, communicate with
obligors under the Receivables and parties to the Contracts to verify with them
to the Administrative Agent's satisfaction the existence, amount and terms of
any Receivables 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, each Grantor shall
notify obligors on the Receivables and parties to the Contracts that the
Receivables and the Contracts have been assigned to the Administrative Agent for
the ratable benefit of the Lenders and that payments in respect thereof shall be
made directly to the Administrative Agent.

<Page>

     (c)    Anything herein to the contrary notwithstanding, each Grantor shall
remain liable under each of the Receivables and Contracts to observe and perform
all of 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 Receivable (or any agreement giving rise
thereto) or Contract by reason of or arising out of this Agreement or the
receipt by the Administrative Agent or any Lender of any payment relating
thereto, nor shall the Administrative Agent or any Lender be obligated in any
manner to perform any of the obligations of any Grantor under or pursuant to any
Receivable (or any agreement giving rise thereto) or Contract, 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 which 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 Grantor of the Administrative Agent's intent to exercise its
corresponding rights pursuant to Section 6.3(b), each Grantor shall be permitted
to receive all cash dividends paid in respect of the Pledged Stock and all
payments made in respect of the Pledged Notes, in each case paid to the extent
permitted in the Credit Agreement, and to exercise all voting and corporate or
other organizational rights with respect to the Investment Property; PROVIDED,
however, that no vote shall be cast or corporate or other organizational right
exercised or other action taken which, in the Administrative Agent's reasonable
judgment, would impair the Collateral or which would result in any violation of
any provision of the Credit Agreement, this Agreement or any other Loan
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 Grantor or Grantors, (i) the Administrative Agent shall have the
right to receive any and all cash dividends, payments or other Proceeds paid in
respect of the Investment Property (other than cash dividends, payments and
other Proceeds permitted to be paid pursuant to Section 7.6(c) of the Credit
Agreement) and make application thereof to the Obligations in such order as the
Administrative Agent may reasonably determine, and (ii) any or all of the
Investment Property 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
Investment Property at any meeting of shareholders of the relevant Issuer or
Issuers or otherwise and (y) any and all rights of conversion, exchange and
subscription and any other rights, privileges or options pertaining to such
Investment Property as if it were the absolute owner thereof (including, without
limitation, the right to exchange at its discretion any and all of the
Investment Property upon the merger, consolidation, reorganization,
recapitalization or other fundamental change in the corporate or other
organizational structure of any Issuer, or upon the exercise by any Grantor or
the Administrative Agent of any right, privilege or option pertaining to such
Investment Property, and in connection therewith, the right to deposit and
deliver any and all of the Investment Property 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 except to account for property actually received by it, but the
Administrative Agent shall have no duty to any Grantor to exercise any such
right, privilege or option and shall not be responsible for any failure to do so
or delay in so doing.

     (c)    Each Grantor hereby authorizes and instructs each Issuer of any
Investment Property pledged by such Grantor 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 Grantor, and each Grantor agrees that each Issuer
shall be fully protected in so complying, and

<Page>

(ii) to the extent expressly required hereby, pay any dividends or other
payments with respect to the Investment Property 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 Lenders specified in Section 6.1
with respect to payments of Receivables, if an Event of Default shall occur and
be continuing, at the request of the Administrative Agent, all Proceeds received
by any Grantor consisting of cash, checks and other near-cash items shall be
held by such Grantor in trust for the Administrative Agent and the Lenders,
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 a Collateral Account maintained
under its sole dominion and control. All Proceeds while held by the
Administrative Agent in a Collateral Account (or by such Grantor in trust for
the Administrative Agent and the Lenders) shall continue to be held as
collateral security for all the Obligations and shall not constitute payment
thereof until applied as provided in Section 6.5.

     6.5    APPLICATION OF PROCEEDS. At such intervals as may be agreed upon by
the Borrower and the Administrative Agent, or, if an Event of Default shall have
occurred and be continuing, at any time at the Administrative Agent's election,
the Administrative Agent may apply all or any part of Proceeds constituting
Collateral, whether or not held in any Collateral Account, in payment of the
Obligations in such order as the Administrative Agent may reasonably elect, and
any part of such funds which the Administrative Agent elects not so to apply and
deems not required as collateral security for the Obligations shall be paid over
from time to time by the Administrative Agent to the Borrower or to whomsoever
may be lawfully entitled to receive the same. Any balance of such Proceeds
remaining after the Obligations (other than contingent obligations and
liabilities) shall have been paid in full, no Letters of Credit shall be
outstanding and the Commitments shall have terminated shall be paid over to the
Borrower 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 Lenders, 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, all rights and remedies of a secured party under the New York UCC
or any other applicable law. Without limiting the generality of the foregoing,
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 Grantor or any other Person
(all and each of which demands, defenses, advertisements and notices are hereby
waived to the extent permitted by applicable law), may in such circumstances
forthwith collect, receive, appropriate and realize upon the 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 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 Lender 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, in accordance with applicable law. The
Administrative Agent or any Lender 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 Collateral so sold, free of
any right or equity of redemption in any Grantor, which right or equity is
hereby waived and released. Each Grantor further agrees, at the Administrative
Agent's request, to assemble the Collateral and make it available to the
Administrative Agent at places which the Administrative Agent shall reasonably
select, whether at such Grantor'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 Collateral or in any way

<Page>

relating to the Collateral or the rights of the Administrative Agent and the
Lenders hereunder, including, without limitation, reasonable attorneys' fees and
disbursements, to the payment in whole or in part of the Obligations, in such
order as the Administrative Agent may elect, 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 9-615(a)(3) of the
New York UCC. To the extent permitted by applicable law, each Grantor waives all
claims, damages and demands it may acquire against the Administrative Agent or
any Lender arising out of the exercise by them of any rights hereunder other
than with respect to claims, damages and demands resulting from the gross
negligence or willful misconduct of the Administrative Agent or any Lender. 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 that portion of the Pledged Stock
that is the Capital Stock of the Borrower pursuant to Section 6.6, and if in the
opinion of the Administrative Agent it is necessary or advisable to have such
Pledged Stock, or that portion thereof to be sold, registered under the
provisions of the Securities Act, the Borrower will (i) execute and deliver, and
cause its directors and officers 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
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 best efforts to cause the registration statement
relating thereto to become effective and to remain effective for a period of 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 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. The Borrower agrees to comply with the provisions
of the securities or "Blue Sky" laws of any and all jurisdictions which the
Administrative Agent shall designate and to make available to its security
holders, as soon as practicable, an earnings statement (which need not be
audited) which will satisfy the provisions of Section 11(a) of the Securities
Act.

     (b)    Each Grantor recognizes that the Administrative Agent may be unable
to effect a public sale of any or all the 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. Each
Grantor 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. 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)    Each Grantor agrees to use its commercially reasonable efforts to do
or cause to be done all such other acts as may be reasonably necessary to make
such sale or sales of all or any portion of the Pledged Stock pursuant to this
Section 6.7 valid and binding and in compliance with any and all other
applicable Requirements of Law. Each Grantor 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 Grantor, and such Grantor 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
under the Credit Agreement.

<Page>

     6.8    INTELLECTUAL PROPERTY. In the event that the Loans become due and
payable pursuant to Section 8 of the Credit Agreement, the Administrative Agent
shall have the right to license the Intellectual Property of any Grantor to any
Person without the consent of such Grantor or any other Loan Party and such
Grantor shall take any action required by the Administrative Agent to enable the
Administrative Agent to so license such Intellectual Property.

     6.9    DEFICIENCY. Each Grantor shall remain liable for any deficiency if
the proceeds of any sale or other disposition of the Collateral are insufficient
to pay its Obligations and the fees and disbursements of any attorneys employed
by the Administrative Agent or any Lender to collect such deficiency.

                       SECTION 7. THE ADMINISTRATIVE AGENT

     7.1    ADMINISTRATIVE AGENT'S APPOINTMENT AS ATTORNEY-IN-FACT, ETC. (a)
Each Grantor hereby irrevocably constitutes and appoints the Administrative
Agent and any 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 Grantor and in the name of such Grantor 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 which may be reasonably necessary or desirable to accomplish the
purposes of this Agreement, and, without limiting the generality of the
foregoing, 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 Receivable or
   Contract or with respect to any other Collateral and file any claim or take
   any other action or proceeding in any court of law or equity or otherwise
   deemed reasonably appropriate by the Administrative Agent for the purpose of
   collecting any and all such moneys due under any Receivable or Contract or
   with respect to any other Collateral whenever payable;

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

     (iii)  pay or discharge taxes and Liens levied or placed on or threatened
   against the Collateral, 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;

     (iv)   execute, in connection with any sale provided for in Section 6.6 or
   6.7, any indorsements, assignments or other instruments of conveyance or
   transfer with respect to the Collateral; and

     (v)    (1) direct any party liable for any payment under any of the
   Collateral 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; (2) ask or demand for, collect, and 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; (3)
   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; (4) commence and prosecute any suits, actions or proceedings at
   law or in equity in any court of competent jurisdiction to collect the

<Page>

   Collateral or any portion thereof and to enforce any other right in respect
   of any Collateral; (5) defend any suit, action or proceeding brought against
   such Grantor with respect to any Collateral; (6) settle, compromise or adjust
   any such suit, action or proceeding and, in connection therewith, give such
   discharges or releases as the Administrative Agent may deem reasonably
   appropriate; (7) assign any Copyright, Patent or Trademark (along with the
   goodwill of the business to which any such Copyright, Patent or Trademark
   pertains), throughout the world for such term or terms, on such conditions,
   and in such manner, as the Administrative Agent shall in its sole discretion
   reasonably determine; and (8) generally, sell, transfer, pledge and make any
   agreement with respect to or otherwise deal with any of the Collateral 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 reasonably necessary to protect,
   preserve or realize upon the Collateral and the Administrative Agent's and
   the Lenders' security interests therein and to effect the intent of this
   Agreement, all as fully and effectively as such Grantor might do.

   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)    If any Grantor fails to perform or comply with any of its agreements
contained herein, the Administrative Agent, at its option, but without any
obligation so to do, may perform or comply, or otherwise cause performance or
compliance, with such agreement.

     (c)    The 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 highest rate per annum at which
interest would then be payable on any category of past due ABR Loans under the
Credit Agreement, from the date on which the Administrative Agent requests
reimbursement from the relevant Grantor, shall be payable by such Grantor to the
Administrative Agent on demand.

     (d)    Each Grantor 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
until this Agreement is terminated and the security interests 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
Collateral in its possession, under Section 9-207 of the New York UCC 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 Lender nor any of their respective officers,
directors, employees or agents shall be liable for failure to demand, collect or
realize upon any of the Collateral or for any delay in doing so or shall be
under any obligation to sell or otherwise dispose of any Collateral upon the
request of any Grantor or any other Person or to take any other action
whatsoever with regard to the Collateral or any part thereof. The powers
conferred on the Administrative Agent and the Lenders hereunder are solely to
protect the Administrative Agent's and the Lenders' interests in the Collateral
and shall not impose any duty upon the Administrative Agent or any Lender to
exercise any such powers. The Administrative Agent and the Lenders 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 Grantor for any act or failure
to act hereunder, except for their own gross negligence or willful misconduct.

     7.3    EXECUTION OF FINANCING STATEMENTS. Pursuant to any applicable law,
each Grantor authorizes the Administrative Agent to file or record financing
statements and other filing or recording

<Page>

documents or instruments with respect to the Collateral without the signature of
such Grantor in such form and in such offices as the Administrative Agent
reasonably determines appropriate to perfect the security interests of the
Administrative Agent under this Agreement. Each Grantor authorizes the
Administrative Agent to use the collateral description "all personal property"
in any such financing statements.

     7.4    AUTHORITY OF ADMINISTRATIVE AGENT. Each Grantor 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 shall, as between the Administrative Agent and the
Lenders, 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 Grantors, the Administrative Agent shall be
conclusively presumed to be acting as agent for the Lenders with full and valid
authority so to act or refrain from acting, and no Grantor shall be under any
obligation, or entitlement, to make any inquiry respecting such authority.

                            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 in
accordance with Section 10.1 of the Credit Agreement.

     8.2    NOTICES. All notices, requests and demands to or upon the
Administrative Agent or any Grantor hereunder shall be effected in the manner
provided for in Section 10.2 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 with a copy to be
delivered to each of the Borrower and its counsel as set forth in Section 10.2
of the Credit Agreement.

     8.3    NO WAIVER BY COURSE OF CONDUCT; CUMULATIVE REMEDIES. Neither the
Administrative Agent nor any Lender 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. No failure to exercise, nor any delay in
exercising, on the part of the Administrative Agent or any Lender, 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 Lender 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 Lender 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 agrees to
pay or reimburse each Lender and the Administrative Agent for all its costs and
expenses incurred in collecting against such Guarantor under the guarantee
contained in Section 2 or otherwise enforcing or preserving any rights under
this Agreement and the other Loan Documents to which such Guarantor is a party,
including, without limitation, the fees and disbursements of counsel (including
the allocated fees and expenses of in-house counsel) to each Lender and of
counsel to the Administrative Agent.

     (b)    Each Guarantor agrees to pay, and to save the Administrative Agent
and the Lenders harmless from, any and all liabilities with respect to, or
resulting from any delay in paying, any and all

<Page>

stamp, excise, sales or other taxes which may be payable or determined to be
payable with respect to any of the Collateral or in connection with any of the
transactions contemplated by this Agreement.

     (c)    Each Guarantor agrees to pay, and to save the Administrative Agent
and the Lenders harmless from, 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 to the extent the
Borrower would be required to do so pursuant to Section 10.5 of the Credit
Agreement.

     (d)    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 Loan Documents.

     8.5    SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the
successors and assigns of each Grantor and shall inure to the benefit of the
Administrative Agent and the Lenders and their successors and assigns; PROVIDED
that no Grantor 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 Grantor hereby irrevocably authorizes the
Administrative Agent and each Lender (but excluding any Participant) if an Event
of Default has occurred and is continuing, without prior notice to such Grantor
or any other Grantor, any such prior notice being expressly waived by each
Grantor, to set-off and appropriate and apply any and all deposits (general or
special, time or demand, provisional or final), 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 Lender to or for the credit or the
account of such Grantor, or any part thereof in such amounts as the
Administrative Agent or such Lender may elect, against and on account of the
obligations and liabilities of such Grantor to the Administrative Agent or such
Lender hereunder and claims of every nature and description of the
Administrative Agent or such Lender against such Grantor, in any currency,
whether arising hereunder, under the Credit Agreement, any other Loan Document
or otherwise, as the Administrative Agent or such Lender may elect, whether or
not the Administrative Agent or any Lender has made any demand for payment and
although such obligations, liabilities and claims may be contingent or
unmatured. The Administrative Agent and each Lender shall notify such Grantor
promptly of any such set-off and the application made by the Administrative
Agent or such Lender 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 Lender 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 Lender may have.

     8.7    COUNTERPARTS. This Agreement may be executed by one or more of the
parties to this Agreement on any number of separate counterparts (including by
telecopy), and all of said counterparts taken together shall be deemed to
constitute one and the same instrument.

     8.8    SEVERABILITY. Any provision of this Agreement which is 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.

     8.9    SECTION HEADINGS. The Section headings used in this Agreement are
for convenience of reference only and are not to affect the construction hereof
or be taken into consideration in the interpretation hereof.

<Page>

     8.10   INTEGRATION. This Agreement and the other Loan Documents represent
the agreement of the Grantors, the Administrative Agent and the Lenders with

undertakings, representations or warranties by the Administrative Agent or any
Lender relative to subject matter hereof and thereof not expressly set forth or
referred to herein or in the other Loan Documents.

     8.11   GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED
AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

     8.12   SUBMISSION TO JURISDICTION; WAIVERS. Each Grantor hereby irrevocably
and unconditionally:

     (a)    submits for itself and its property in any legal action or
proceeding relating to this Agreement and the other Loan Documents to which it
is a party, or for recognition and enforcement of any judgment in respect
thereof, to the non-exclusive general jurisdiction of the courts of the State of
New York, the courts of the United States of America for the Southern District
of New York, and appellate courts from any thereof;

     (b)    consents that any such action or proceeding may be brought in such
courts and waives any objection that it may now or hereafter have to the venue
of any such action or proceeding in any such court or that such action or
proceeding was brought in an inconvenient court and agrees not to plead or claim
the same;

     (c)    agrees that service of process in any such action or proceeding may
be effected by mailing a copy thereof by registered or certified mail (or any
substantially similar form of mail), postage prepaid, to such Grantor at its
address referred to in Section 8.2 or at such other address of which the
Administrative Agent shall have been notified pursuant thereto;

     (d)    agrees that nothing herein shall affect the right to effect service
of process in any other manner permitted by law or shall limit the right to sue
in any other jurisdiction; and

     (e)    waives, to the maximum extent not prohibited by law, any right it
may have to claim or recover in any legal action or proceeding referred to in
this Section any special, exemplary, punitive or consequential damages.

     8.13   ACKNOWLEDGEMENTS. Each Grantor hereby acknowledges that:

     (a)    it has been advised by counsel in the negotiation, execution and
delivery of this Agreement and the other Loan Documents to which it is a party;

     (b)    neither the Administrative Agent nor any Lender has any fiduciary
relationship with or duty to any Grantor arising out of or in connection with
this Agreement or any of the other Loan Documents, and the relationship between
the Grantors, on the one hand, and the Administrative Agent and Lenders, on the
other hand, in connection herewith or therewith is solely that of debtor and
creditor; and

     (c)    no joint venture is created hereby or by the other Loan Documents or
otherwise exists by virtue of the transactions contemplated hereby among the
Lenders or among the Grantors and the Lenders.

<Page>

     8.14   ADDITIONAL GRANTORS. Each Subsidiary of the Borrower that is
required to become a party to this Agreement pursuant to Section 6.9 of the
Credit Agreement shall become a Grantor for all purposes of this Agreement upon
execution and delivery by such Subsidiary of an Assumption Agreement in the form
of Annex 1 hereto.

     8.15   RELEASES. (a) At such time as the Loans, the Reimbursement
Obligations and the other Obligations (other than Obligations in respect of
Specified Swap Agreements and contingent obligations and liabilities) shall have
been paid in full, the Commitments have been terminated and no Letters of Credit
shall be outstanding, the Collateral shall be automatically released from the
Liens created hereby, and this Agreement and all obligations (other than those
expressly stated to survive such termination) of the Administrative Agent and
each Grantor hereunder shall terminate, all without delivery of any instrument
or performance of any act by any party, and all rights to the Collateral shall
revert to the Grantors. At the request and sole expense of any Grantor following

disposed of by any Grantor in a transaction permitted by the Credit Agreement
(including indirectly through the sale, transfer or other disposition of the
Capital Stock of a Subsidiary Guarantor), or otherwise permitted by the Required
Lenders pursuant to Section 10.1 of the Credit Agreement, the Lien of the
Administrative Agent in such Collateral shall be, and is hereby deemed to be,
automatically released and the Administrative Agent, at the request and sole
expense of such Grantor, shall execute and deliver to such Grantor all releases
or other documents reasonably necessary or desirable for the release of the
Liens created hereby on such Collateral. At the request and sole expense of the
Borrower, a Subsidiary Guarantor shall be, and is hereby deemed to be,
automatically released from its obligations hereunder in the event that all the
Capital Stock of such Subsidiary Guarantor shall be sold, transferred or
otherwise disposed of in a transaction permitted by the Credit Agreement or
otherwise permitted by the Required Lenders pursuant to Section 10.1 of the
Credit Agreement.

     8.16   CONSTRUCTION. In the event of any inconsistency between the terms of
