warranties to the Administrative Agent for the benefit of the Secured Creditors
and hereby covenants and agrees with each other Guarantor and the Administrative
Agent for the benefit of the Secured Creditors as follows:

          1. GUARANTY. (a) Each Guarantor, jointly and severally, irrevocably,
absolutely and unconditionally guarantees as a primary obligor and not merely as
surety:

          (i) to the Lender Creditors the full and prompt payment when due
     (whether at the stated maturity, by required prepayment, declaration,
     acceleration, demand or otherwise) of (x) the principal of (or, Face Amount
     of, as applicable), premium, if any, and interest on the Notes issued by,
     and the Loans made to, each of the Borrowers under the Credit Agreement,
     and all reimbursement obligations and Unpaid Drawings with respect to
     Letters of Credit and (y) all other obligations (including, without
     limitation, obligations which, but for the automatic stay under Section
     362(a) of the Bankruptcy Code, would become due), liabilities and
     indebtedness owing by each Borrower to the Lender Creditors under each
     Credit Document to which such Borrower is a party (including, without
     limitation, indemnities, Fees and interest thereon (including, without
     limitation, any interest accruing after the commencement of any bankruptcy,
     insolvency, receivership or similar proceeding at the rate provided for in
     the Credit Agreement, whether or not such interest is an allowed claim in
     any such proceeding)), whether now existing or hereafter incurred under,
     arising out of or in connection with each such Credit Document and the due
     performance and compliance by each Borrower with all of the terms,
     conditions, covenants and agreements contained in all such Credit Documents
     (all such principal (or, Face Amount, as applicable), premium, interest,
     liabilities, indebtedness and obligations under this clause (i), except to
     the extent consisting of obligations or liabilities with respect to Secured
     Hedging Agreements, being herein collectively called the "Credit Document
     Obligations"); and

          (ii) to each Other Creditor the full and prompt payment when due
     (whether at the stated maturity, by required prepayment, declaration,
     acceleration, demand or otherwise) of all obligations (including, without
     limitation, obligations which, but for the

     automatic stay under Section 362(a) of the Bankruptcy Code, would become
     due), liabilities and indebtedness (including, without limitation, any
     interest accruing after the commencement of any bankruptcy, insolvency,
     receivership or similar proceeding at the rate provided for in the
     respective Secured Hedging Agreements, whether or not such interest is an
     allowed claim in any such proceeding) owing by each Borrower and each other
     Guaranteed Party under each Secured Hedging Agreement to which it is a
     party, whether now in existence or hereafter arising, and the due
     performance and compliance by each Borrower and each such other Guaranteed
     Party with all of the terms, conditions, covenants and agreements contained
     therein (all such obligations, liabilities and indebtedness being herein
     collectively called the "Other Obligations", and together with the Credit
     Document Obligations are herein collectively called the "Guaranteed
     Obligations").

As used herein, the term "Guaranteed Party" shall mean each Borrower and each
other Subsidiary of Holdings party to any Secured Hedging Agreement. Each
Guarantor understands, agrees and confirms that the Secured Creditors may
enforce this Guaranty up to the full amount of the Guaranteed Obligations
against such Guarantor without proceeding against any other Guarantor, either
Borrower or any other Guaranteed Party, or against any security for the
Guaranteed Obligations, or under any other guaranty covering all or a portion of
the Guaranteed Obligations. This Guaranty is a guaranty of prompt payment and
performance and not of collection.

          (b) Additionally, each Guarantor, jointly and severally,
unconditionally, absolutely and irrevocably, guarantees the payment of any and
all Guaranteed Obligations whether or not due or payable by either Borrower or
any such other Guaranteed Party upon the occurrence in respect of either
Borrower or any other Guaranteed Party of any of the events specified in clauses
(h), (i) or (j) of Section 11 of the Credit Agreement, and unconditionally,
absolutely and irrevocably, jointly and severally, promises to pay such
Guaranteed Obligations to the Secured Creditors, or order, on demand.

          2. LIABILITY OF GUARANTORS ABSOLUTE. The liability of each Guarantor
hereunder is primary, absolute, joint and several, and unconditional and is
exclusive and independent of any security for or other guaranty of the
indebtedness of either Borrower or any other Guaranteed Party whether executed
by such Guarantor, any other Guarantor, any other guarantor or by any other
party, and the liability of each Guarantor hereunder shall not be affected or
impaired by any circumstance or occurrence whatsoever, including, without
limitation: (a) any direction as to application of payment by either Borrower,
any other Guaranteed Party or any other party, (b) any other continuing or other
guaranty, undertaking or maximum liability of a Guarantor or of any other party
as to the Guaranteed Obligations, (c) any payment on or in reduction of any such
other guaranty or undertaking, (d) any dissolution, termination or increase,
decrease or change in personnel by either Borrower or any other Guaranteed
Party, (e) the failure of the Guarantor to receive any benefit from or as a
result of its execution, delivery and performance of this Guaranty, (f) any
payment made to any Secured Creditor on the indebtedness which any Secured
Creditor repays either Borrower or any other Guaranteed Party pursuant to court
order in any bankruptcy, reorganization, arrangement, moratorium or other debtor
relief proceeding, and each Guarantor waives any right to the

deferral or modification of its obligations hereunder by reason of any such
proceeding, (g) any action or inaction by the Secured Creditors as contemplated
in Section 5 hereof or (h) any invalidity, rescission, irregularity or
unenforceability of all or any part of the Guaranteed Obligations or of any
security therefor.

          3. OBLIGATIONS OF GUARANTORS INDEPENDENT. The obligations of each
Guarantor hereunder are independent of the obligations of any other Guarantor,
any other guarantor, either Borrower or any other Guaranteed Party, and a
separate action or actions may be brought and prosecuted against each Guarantor
whether or not action is brought against any other Guarantor, any other
guarantor, either Borrower or any other Guaranteed Party and whether or not any
other Guarantor, any other guarantor, either Borrower or any other Guaranteed
Party be joined in any such action or actions. Each Guarantor waives (to the
fullest extent permitted by applicable law) the benefits of any statute of
limitations affecting its liability hereunder or the enforcement thereof. Any
payment by either Borrower or any other Guaranteed Party or other circumstance
which operates to toll any statute of limitations as to such Borrower or such
other Guaranteed Party shall operate to toll the statute of limitations as to
each Guarantor.

          4. WAIVERS BY GUARANTORS. (a) Each Guarantor hereby waives (to the
fullest extent permitted by applicable law) notice of acceptance of this
Guaranty and notice of the existence, creation or incurrence of any new or
additional liability to which it may apply, and waives promptness, diligence,
presentment, demand of payment, demand for performance, protest, notice of
dishonor or nonpayment of any such liabilities, suit or taking of other action
by the Administrative Agent or any other Secured Creditor against, and any other
notice to, any party liable thereon (including such Guarantor, any other
Guarantor, any other guarantor, either Borrower or any other Guaranteed Party)
and each Guarantor further hereby waives any and all notice of the creation,
renewal, extension or accrual of any of the Guaranteed Obligations and notice or
proof of reliance by any Secured Creditor upon this Guaranty, and the Guaranteed
Obligations shall conclusively be deemed to have been created, contracted or
incurred, or renewed, extended, amended, modified, supplemented or waived, in
reliance upon this Guaranty.

          (b) Each Guarantor waives any right to require the Secured Creditors
to: (i) proceed against either Borrower, any other Guaranteed Party, any other
Guarantor, any other guarantor of the Guaranteed Obligations or any other party;
(ii) proceed against or exhaust any security held from either Borrower, any
other Guaranteed Party, any other Guarantor, any other guarantor of the
Guaranteed Obligations or any other party; or (iii) pursue any other remedy in
the Secured Creditors' power whatsoever. Each Guarantor waives any defense based
on or arising out of any defense of either Borrower, any other Guaranteed Party,
any other Guarantor, any other guarantor of the Guaranteed Obligations or any
other party other than payment in full in cash of the Guaranteed Obligations,
including, without limitation, any defense based on or arising out of the
disability of either Borrower, any other Guaranteed Party, any other Guarantor,
any other guarantor of the Guaranteed Obligations or any other party, or the
unenforceability of the Guaranteed Obligations or any part thereof from any
cause, or the cessation from any cause of the liability of either Borrower or
any other Guaranteed Party other than payment in full in cash of the Guaranteed
Obligations. The Secured Creditors may, at their election, foreclose on any
collateral serving as security held by the Administrative Agent, the Collateral
Agent or the

other Secured Creditors by one or more judicial or nonjudicial sales, whether or
not every aspect of any such sale is commercially reasonable (to the extent such
sale is permitted by applicable law), or exercise any other right or remedy the
Secured Creditors may have against either Borrower, any other Guaranteed Party
or any other party, or any security, without affecting or impairing in any way
the liability of any Guarantor hereunder except to the extent the Guaranteed
Obligations have been paid in full in cash. Each Guarantor waives any defense
arising out of any such election by the Secured Creditors, even though such
election operates to impair or extinguish any right of reimbursement,
contribution, indemnification or subrogation or other right or remedy of such
Guarantor against either Borrower, any other Guaranteed Party, any other
guarantor of the Guaranteed Obligations or any other party or any security.

          (c) Each Guarantor has knowledge and assumes all responsibility for
being and keeping itself informed of each Borrower's, each other Guaranteed
Party's and each other Guarantor's financial condition, affairs and assets, and
of all other circumstances bearing upon the risk of nonpayment of the Guaranteed
Obligations and the nature, scope and extent of the risks which such Guarantor
assumes and incurs hereunder, and has adequate means to obtain from each
Borrower, each other Guaranteed Party and each other Guarantor on an ongoing
basis information relating thereto and each Borrower's, each other Guaranteed
Party's and each other Guarantor's ability to pay and perform its respective
Guaranteed Obligations, and agrees to assume the responsibility for keeping, and
to keep, so informed for so long as this Guaranty is in effect. Each Guarantor
acknowledges and agrees that (x) the Secured Creditors shall have no obligation
to investigate the financial condition or affairs of either Borrower, any other
Guaranteed Party or any other Guarantor for the benefit of such Guarantor nor to
advise such Guarantor of any fact respecting, or any change in, the financial
condition, assets or affairs of either Borrower, any other Guaranteed Party or
any other Guarantor that might become known to any Secured Creditor at any time,
whether or not such Secured Creditor knows or believes or has reason to know or
believe that any such fact or change is unknown to such Guarantor, or might (or
does) increase the risk of such Guarantor as guarantor hereunder, or might (or
would) affect the willingness of such Guarantor to continue as a guarantor of
the Guaranteed Obligations hereunder and (y) the Secured Creditors shall have no
duty to advise any Guarantor of information known to them regarding any of the
aforementioned circumstances or risks.

          (d) Each Guarantor hereby acknowledges and affirms that it understands
that to the extent the Guaranteed Obligations are secured by Real Property
located in the State of California, such Guarantor shall be liable for the full
amount of the liability hereunder notwithstanding foreclosure on such Real
Property by trustee sale or any other reason impairing such Guarantor's or any
Secured Creditors' right to proceed against either Borrower, any other
Guaranteed Party or any other guarantor of the Guaranteed Obligations.

          (e) Each Guarantor hereby waives (to the fullest extent permitted by
applicable law) until such time as the Guaranteed Obligations have been
irrevocably paid in full in cash all rights and benefits under Section 580a,
580b, 580d and 726 of the California Code of Civil Procedure. Each Guarantor
hereby further waives (to the fullest extent permitted by applicable law) until
such time as the Guaranteed Obligations have been irrevocably paid in full in
cash, without limiting the generality of the foregoing or any other provision
hereof, all rights

and benefits which might otherwise be available to such Guarantor under Sections
2809, 2810, 2815, 2819, 2821, 2839, 2845, 2848, 2849, 2850, 2899 and 3433 of the
California Civil Code.

          (f) Until the Guaranteed Obligations have been paid in full in cash,
each Guarantor waives its rights of subrogation and reimbursement and any other
rights and defenses available to such Guarantor by reason of Sections 2787 to
2855, inclusive, of the California Civil Code, including, without limitation,
(1) any defenses such Guarantor may have to this Guaranty by reason of an
election of remedies by the Secured Creditors and (2) any rights or defenses
such Guarantor may have by reason of protection afforded to either Borrower or
any other Guaranteed Party pursuant to the antideficiency or other laws of
California limiting or discharging such Borrower's or such other Guaranteed
Party's indebtedness, including, without limitation, Section 580a, 580b, 580d or
726 of the California Code of Civil Procedure. In furtherance of such
provisions, each Guarantor hereby waives all rights and defenses arising out of
an election of remedies by the Secured Creditors, even though that election of
remedies, such as a nonjudicial foreclosure, destroys such Guarantor's rights of
subrogation and reimbursement against either Borrower or any other Guaranteed
Party by the operation of Section 580d of the California Code of Civil Procedure
or otherwise.

          (g) Each Guarantor hereby acknowledges and agrees that no Secured
Creditor nor any other Person shall be under any obligation (a) to marshal any
assets in favor of such Guarantor or in payment of any or all of the liabilities
of any Guaranteed Party under the Credit Documents or the obligation of such
Guarantor hereunder or (b) to pursue any other remedy that such Guarantor may or
may not be able to pursue itself any right to which such Guarantor hereby
waives.

          (h) Each Guarantor warrants and agrees that each of the waivers set
forth in Section 3 and in this Section 4 is made with full knowledge of its
significance and consequences and that if any of such waivers are determined to
be contrary to any applicable law or public policy, such waivers shall be
effective only to the maximum extent permitted by applicable law.

          5. RIGHTS OF SECURED CREDITORS. Subject to Sections 4 and 13, any
Secured Creditor may (except as shall be required by applicable statute and
cannot be waived) at any time and from time to time without the consent of, or
notice to, any Guarantor, without incurring responsibility to such Guarantor,
without impairing or releasing the obligations or liabilities of such Guarantor
hereunder, upon or without any terms or conditions and in whole or in part:

          (a) change the manner, place or terms of payment of, and/or change,
     increase or extend the time of payment of, renew, increase, accelerate or
     alter, any of the Guaranteed Obligations (including, without limitation,
     any increase or decrease in the rate of interest thereon or the principal
     amount thereof), any security therefor, or any liability incurred directly
     or indirectly in respect thereof, and the guaranty herein made shall apply
     to the Guaranteed Obligations as so changed, extended, increased,
     accelerated, renewed or altered;

          (b) take and hold security for the payment of the Guaranteed
     Obligations and sell, exchange, release, surrender, impair, realize upon or
     otherwise deal with in any manner and in any order any property or other
     collateral by whomsoever at any time pledged or mortgaged to secure, or
     howsoever securing, the Guaranteed Obligations or any liabilities
     (including any of those hereunder) incurred directly or indirectly in
     respect thereof or hereof, and/or any offset thereagainst;

          (c) exercise or refrain from exercising any rights against either
     Borrower, any other Guaranteed Party, any other Credit Party, any
     Subsidiary thereof, any other guarantor of either Borrower or any other
     Guaranteed Party or others or otherwise act or refrain from acting;

          (d) release or substitute any one or more endorsers, Guarantors, other
     guarantors, either Borrower, any other Guaranteed Party or other obligors;

          (e) settle or compromise any of the Guaranteed Obligations, any
     security therefor or any liability (including any of those hereunder)
     incurred directly or indirectly in respect thereof or hereof, and may
     subordinate the payment of all or any part thereof to the payment of any
     liability (whether due or not) of either Borrower or any other Guaranteed
     Party to creditors of such Borrower or such other Guaranteed Party other
     than the Secured Creditors;

          (f) apply any sums by whomsoever paid or howsoever realized to any
     liability or liabilities of either Borrower or any other Guaranteed Party
     to the Secured Creditors regardless of what liabilities of such Borrower or
     such other Guaranteed Party remain unpaid;

          (g) consent to or waive any breach of, or any act, omission or default
     under, any of the Secured Hedging Agreements, the Credit Documents or any
     of the instruments or agreements referred to therein, or otherwise amend,
     modify or supplement any of the Secured Hedging Agreements, the Credit
     Documents or any of such other instruments or agreements;

          (h) act or fail to act in any manner which may deprive such Guarantor
     of its right to subrogation against either Borrower or any other Guaranteed
     Party to recover full indemnity for any payments made pursuant to this
     Guaranty; and/or

          (i) take any other action or omit to take any other action which
     would, under otherwise applicable principles of common law, give rise to a
     legal or equitable discharge of such Guarantor from its liabilities under
     this Guaranty (including, without limitation, any action or omission
     whatsoever that might otherwise vary the risk of such Guarantor or
     constitute a legal or equitable defense to or discharge of the liabilities
     of a guarantor or surety or that might otherwise limit recourse against
     such Guarantor).

No invalidity, illegality, irregularity or unenforceability of all or any part
of the Guaranteed Obligations, the Credit Documents or any other agreement or
instrument relating to the

Guaranteed Obligations or of any security or guarantee therefor shall affect,
impair or be a defense to this Guaranty, and this Guaranty shall be primary,
absolute and unconditional notwithstanding the occurrence of any event or the
existence of any other circumstances which might constitute a legal or equitable
discharge of a surety or guarantor except payment in full in cash of the
Guaranteed Obligations.

          6. CONTINUING GUARANTY. This Guaranty is a continuing one and all
liabilities to which it applies or may apply under the terms hereof shall be
conclusively presumed to have been created in reliance hereon. No failure or
delay on the part of any Secured Creditor in exercising any right, power or
privilege hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any right, power or privilege hereunder preclude any other
or further exercise thereof or the exercise of any other right, power or
privilege. The rights and remedies herein expressly specified are cumulative and
not exclusive of any rights or remedies which any Secured Creditor would
otherwise have. No notice to or demand on any Guarantor in any case shall
entitle such Guarantor to any other further notice or demand in similar or other
circumstances or constitute a waiver of the rights of any Secured Creditor to
any other or further action in any circumstances without notice or demand. It is
not necessary for any Secured Creditor to inquire into the capacity or powers of
either Borrower or any other Guaranteed Party or the officers, directors,
partners or agents acting or purporting to act on its or their behalf, and any
indebtedness made or created in reliance upon the professed exercise of such
powers shall be guaranteed hereunder.

          7. SUBORDINATION OF INDEBTEDNESS HELD BY GUARANTORS. Any indebtedness
of either Borrower or any other Guaranteed Party now or hereafter held by any
Guarantor is hereby subordinated to the indebtedness of such Borrower or such
other Guaranteed Party to the Secured Creditors; and such indebtedness of such
Borrower or such other Guaranteed Party to any Guarantor, if the Administrative
Agent or the Collateral Agent, after an Event of Default has occurred and is
continuing, so requests, shall be collected, enforced and received by such
Guarantor as trustee for the Secured Creditors and be paid over to the Secured
Creditors on account of the indebtedness of such Borrower or such other
Guaranteed Party to the Secured Creditors, but without affecting or impairing in
any manner the liability of such Guarantor under the other provisions of this
Guaranty. Prior to the transfer by any Guarantor of any note or negotiable
instrument evidencing any indebtedness of either Borrower or any other
Guaranteed Party to such Guarantor, such Guarantor shall mark such note or
negotiable instrument with a legend that the same is subject to this
subordination. Without limiting the generality of the foregoing, each Guarantor
hereby agrees with the Secured Creditors that it will not exercise any right of
subrogation which it may at any time otherwise have as a result of this Guaranty
(whether contractual, under Section 509 of the Bankruptcy Code or otherwise)
until all Guaranteed Obligations have been irrevocably paid in full in cash;
provided, that if any amount shall be paid to such Guarantor on account of such
subrogation rights at any time prior to the irrevocable payment in full in cash
of all the Guaranteed Obligations, such amount shall be held in trust for the
benefit of the Secured Creditors and shall forthwith be paid to the Secured
Creditors to be credited and applied upon the Guaranteed Obligations, whether
matured or unmatured, in accordance with the terms of the Credit Documents or,
if the Credit Documents do not provide for the application of such amount, to be
held by the Secured Creditors as collateral security for any Guaranteed
Obligations thereafter existing.

          8. GUARANTY ENFORCEABLE BY ADMINISTRATIVE AGENT OR COLLATERAL AGENT.
Notwithstanding anything to the contrary contained elsewhere in this Guaranty,
the Secured Creditors agree (by their acceptance of the benefits of this
Guaranty) that this Guaranty may be enforced only by the action of the
Administrative Agent or the Collateral Agent, in each case acting upon the
instructions of the Required Lenders and that no other Secured Creditor shall
have any right individually to seek to enforce or to enforce this Guaranty or to
realize upon the security to be granted by the Security Documents, it being
understood and agreed that such rights and remedies may be exercised by the
Administrative Agent or the Collateral Agent, for the benefit of the Secured
Creditors upon the terms of this Guaranty and the Security Documents. The
Secured Creditors further agree that this Guaranty may not be enforced against
any director, officer, employee, partner, member or stockholder of any Guarantor
(except to the extent such partner, member or stockholder is also a Guarantor
hereunder). It is understood and agreed that the agreement in this Section 8 is
among and solely for the benefit of the Secured Creditors and that, if the
Required Lenders so agree (without requiring the consent of any Guarantor), this
Guaranty may be directly enforced by any Secured Creditor.

          9. REPRESENTATIONS, WARRANTIES AND COVENANTS OF GUARANTORS. In order
to induce the Lenders to make Loans to, and issue Letters of Credit for the
respective accounts of, the Borrowers pursuant to the Credit Agreement, and in
order to induce the Other Creditors to execute, deliver and perform the Secured
Hedging Agreements to which they are a party, each Guarantor represents,
warrants and covenants that:

          (a) such Guarantor (i) is a duly organized and validly existing
     Company in good standing (or its equivalent) under the laws of the
     jurisdiction of its organization, (ii) has all requisite Company power and
     authority to own its assets, to carry on its business as now conducted and
     as proposed to be conducted and to execute, deliver and perform its
     obligations under each Credit Document to which it is a party and (iii)
     except where the failure to do so, individually or in the aggregate, could
     not reasonably be expected to result in a Material Adverse Effect, is
     qualified to do business in, and is in good standing in, every jurisdiction
     where such qualification is required;

          (b) this Guaranty and each other Credit Document to which it is a
     party has been duly authorized by all necessary Company action and, if
     required, stockholder action;

          (c) this Guaranty has been duly executed and delivered by such
     Guarantor and constitutes, and each other Credit Document to which such
     Guarantor is to be a party, when executed and delivered by such Guarantor,
     will constitute, a legal, valid and binding obligation of such Guarantor
     enforceable in accordance with its terms, subject to applicable bankruptcy,
     insolvency, reorganization, moratorium or other laws affecting creditors'
     rights generally and subject to general principles of equity, regardless of
     whether considered in a proceeding in equity or at law.

          (d) the execution, delivery or performance by such Guarantor of this
     Guaranty and any other Credit Document to which it is a party, nor
     compliance by it with the terms

     and provisions hereof and thereof (a) does not require any consent or
     approval of, registration or filing with, or any other action by, any
     Governmental Authority, except such as have been obtained or made and are
     in full force and effect and except filings necessary to perfect Liens
     created under the Credit Documents, (b) will not violate any Requirement of
     Law applicable to such Guarantor, (c) will not violate or result in a
     default under any indenture or other material agreement or instrument
     binding upon such Guarantor or any of its assets, or give rise to a right
     thereunder to require any payment to be made by such Guarantor or give rise
     to a right of, or result in, termination, cancellation or acceleration of
     any material obligation thereunder (including, without limitation, the
     Senior Notes Indenture and the Senior Subordinated Notes Indenture), and
     (d) will not result in the creation or imposition of any Lien on any asset
     of such Guarantor, except Liens created under the Credit Documents;

          (e) there are no actions, suits or proceedings by or before any
     arbitrator or Governmental Authority pending against or, to the knowledge
     of such Guarantor, threatened against or affecting such Guarantor or any of
     its Subsidiaries (x) that could reasonably be expected, individually or in
     the aggregate, to (i) result in a Material Adverse Effect or (ii) adversely
     affect in any material respect the ability of such Guarantor to consummate
     the Transaction or (y) with respect to this Guaranty or any other Credit
     Document;

          (f) until the termination of the Total Commitment and until such time
     as no Note or Letter of Credit remains outstanding and all Guaranteed
     Obligations have been paid in full (other than indemnities described in
     Section 13.13 of the Credit Agreement and analogous provisions in the
     Security Documents which are not then due and payable), such Guarantor will
     comply, and will cause each of its Subsidiaries to comply, with all of the
     applicable provisions, covenants and agreements contained in Sections 9 and
     10 of the Credit Agreement, and will take, or will refrain from taking, as
     the case may be, all actions that are necessary to be taken or not taken so
     that no violation of any provision, covenant or agreement contained in
     Sections 9 and 10 of the Credit Agreement, and so that no Default or Event
     of Default, is caused by the actions of such Guarantor or any of its
     Subsidiaries; and

          (g) an executed (or conformed) copy of each of the Credit Documents,
     the Secured Hedging Agreements has been made available to a senior officer
     of such Guarantor and such officer is familiar with the contents thereof.

          10. EXPENSES. The Guarantors hereby jointly and severally agree to pay
all reasonable out-of-pocket costs and expenses of the Collateral Agent, the
Administrative Agent and each other Secured Creditor in connection with the
enforcement of this Guaranty and the protection of the Secured Creditors' rights
hereunder and any amendment, waiver or consent relating hereto (including, in
each case, without limitation, the reasonable fees and disbursements of counsel
(including in-house counsel) employed by any of the Collateral Agent, the
Administrative Agent and each other Secured Creditor).

          11. BENEFIT AND BINDING EFFECT. This Guaranty shall be binding upon
each Guarantor and its successors and assigns and shall inure to the benefit of
the Secured Creditors and their successors and assigns.

          12. AMENDMENTS; WAIVERS. Neither this Guaranty nor any provision
hereof may be changed, waived, discharged or terminated except with the written
consent of each Guarantor directly affected thereby (it being understood that
the addition or release of any Guarantor hereunder shall not constitute a
change, waiver, discharge or termination affecting any Guarantor other than the
Guarantor so added or released) and with the written consent of the Required
Lenders (or, to the extent required by Section 13.12 of the Credit Agreement,
with the written consent of each Lender); provided, that any change, waiver,
modification or variance affecting the rights and benefits of a single Class (as
defined below) of Secured Creditors (and not all Secured Creditors in a like or
similar manner) shall also require the written consent of the Requisite
Creditors (as defined below) of such Class of Secured Creditors. For the purpose
of this Guaranty, the term "Class" shall mean each class of Secured Creditors,
i.e., whether (x) the Lender Creditors as holders of the Credit Document
Obligations or (y) the Other Creditors as the holders of the Other Obligations.
For the purpose of this Guaranty, the term "Requisite Creditors" of any Class
shall mean (x) with respect to the Credit Document Obligations, the Required
Lenders (or, to the extent required by Section 13.12 of the Credit Agreement,
each Lender) and (y) with respect to the Other Obligations, the holders of at
least a majority of all Other Obligations outstanding from time to time under
the Secured Hedging Agreements.

          13. SET OFF. In addition to any rights now or hereafter granted under
applicable law (including, without limitation, Section 151 of the New York
Debtor and Creditor Law) and not by way of limitation of any such rights, upon
the occurrence and during the continuance of an Event of Default, each Secured
Creditor is hereby authorized, at any time or from time to time, without notice
to any Guarantor or to any other Person, any such notice being expressly waived,
to set off and to appropriate and apply any and all deposits (general or
special) and any other indebtedness at any time held or owing by such Secured
Creditor to or for the credit or the account of such Guarantor, against and on
account of the obligations and liabilities of such Guarantor to such Secured
Creditor under this Guaranty, irrespective of whether or not such Secured
Creditor shall have made any demand hereunder and although said obligations,
liabilities, deposits or claims, or any of them, shall be contingent or
unmatured. Notwithstanding anything to the contrary contained in this Guaranty,
at any time that the Guaranteed Obligations shall be secured by any Real
Property located in the State of California, no Secured Creditor shall exercise
any right of set-off, lien or counterclaim or take any court or administrative
action or institute any proceedings to enforce any provision of this Guaranty
without the prior consent of the Administrative Agent or the Required Lenders
or, to the extent required by Section 13.12 of the Credit Agreement, all of the
Lenders, if such setoff or action or proceeding would or might (pursuant to
Sections 580a, 580b, 580d and 726 of the California Code of Civil Procedure or
Section 2924 of the California Civil Code, if applicable, or otherwise) affect
or impair the validity, priority, or enforceability of the liens granted to the
Collateral Agent pursuant to the Security Documents or the enforceability of the
Guaranteed Obligations hereunder, and any attempted exercise by any Secured
Creditor or the Administrative Agent of any such right without obtaining such
consent of the Required Lenders or the Administrative Agent shall be null and
void. It is understood and agreed that the foregoing sentence of this Section 13
is for the

sole benefit of the Secured Creditors and may be amended, modified or waived in
any respect by the Required Lenders (without any requirement of prior notice to
or consent by any Credit Party or any other Person) and does not constitute a
waiver of any rights against any Credit Party or against any Collateral. Each
Secured Creditor (by its acceptance of the benefits hereof) acknowledges and
agrees that the provisions of this Section 13 are subject to the sharing
provisions set forth in Section 13.06 of the Credit Agreement.

          14. NOTICE. Except as otherwise specified herein, all notices,
requests, demands or other communications to or upon the respective parties
hereto shall be sent or delivered by mail, telecopy or courier service and all
such notices and communications shall, when mailed, telecopied or sent by
courier, be effective when deposited in the mails or delivered to the overnight
courier, as the case may be, except that notices and communications to the
Administrative Agent or any Guarantor shall not be effective until received by
the Administrative Agent or such Guarantor, as the case may be. All notices and
other communications shall be in writing and addressed to such party at (i) in
the case of any Lender Creditor, as provided in the Credit Agreement, (ii) in
the case of any Guarantor, to the care of the U.S. Borrower to the address
specified in Section 13.03 of the Credit Agreement, and (iii) in the case of any
Other Creditor, at such address as such Other Creditor shall have specified in
writing to the Guarantors; or in any case at such other address as any of the
Persons listed above may hereafter notify the others in writing.

          15. REINSTATEMENT. If any claim is ever made upon any Secured Creditor
for repayment or recovery of any amount or amounts received in payment or on
account of any of the Guaranteed Obligations and any of the aforesaid payees
repays all or part of said amount by reason of (i) any judgment, decree or order
of any court or administrative body having jurisdiction over such payee or any
of its property or (ii) any settlement or compromise of any such claim effected
by such payee with any such claimant (including, without limitation, either
Borrower or any other Guaranteed Party), then and in such event each Guarantor
agrees that any such judgment, decree, order, settlement or compromise shall be
binding upon such Guarantor, notwithstanding any revocation hereof or the
cancellation of any Note, any Secured Hedging Agreement or any other instrument
evidencing any liability of either Borrower or any other Guaranteed Party, and
such Guarantor shall be and remain liable to the aforesaid payees hereunder for
the amount so repaid or recovered to the same extent as if such amount had never
originally been received by any such payee.

          16. CONSENT TO JURISDICTION; SERVICE OF PROCESS; AND WAIVER OF TRIAL
BY JURY. (a) THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE SECURED
CREDITORS AND OF THE UNDERSIGNED HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK. Any legal action or proceeding
with respect to this Guaranty or any other Credit Document to which any
Guarantor is a party may be brought in the courts of the State of New York or of
the United States of America for the Southern District of New York, in each case
located within the City of New York, and, by execution and delivery of this
Guaranty, each Guarantor hereby irrevocably accepts for itself and in respect of
its property, generally and unconditionally, the jurisdiction of the aforesaid
courts. Each Guarantor hereby further irrevocably waives any claim that any such
courts lack jurisdiction over such Guarantor, and

agrees not to plead or claim, in any legal action or proceeding with respect to
this Guaranty or any other Credit Document to which such Guarantor is a party
brought in any of the aforesaid courts, that any such court lacks jurisdiction
over such Guarantor. Each Guarantor further irrevocably consents to the service
of process out of any of the aforementioned courts in any such action or
proceeding by the mailing of copies thereof by registered or certified mail,
postage prepaid, to each Guarantor as set forth in Section 14 hereof, such
service to become effective 30 days after such mailing. Each Guarantor hereby
irrevocably waives any objection to such service of process and further
irrevocably waives and agrees not to plead or claim in any action or proceeding
commenced hereunder or under any other Credit Document to which such Guarantor
is a party that such service of process was in any way invalid or ineffective.
Nothing herein shall affect the right of any of the Secured Creditors to serve
process in any other manner permitted by law or to commence legal proceedings or
otherwise proceed against each Guarantor in any other jurisdiction.

          (b) Each Guarantor hereby irrevocably waives (to the fullest extent
permitted by applicable law) any objection which it may now or hereafter have to
the laying of venue of any of the aforesaid actions or proceedings arising out
of or in connection with this Guaranty or any other Credit Document to which
such Guarantor is a party brought in the courts referred to in clause (a) above
and hereby further irrevocably waives and agrees not to plead or claim in any
such court that such action or proceeding brought in any such court has been
brought in an inconvenient forum.

          (c) EACH GUARANTOR AND EACH SECURED CREDITOR (BY ITS ACCEPTANCE OF THE
BENEFITS OF THIS GUARANTY) HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO A TRIAL BY
JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO
THIS GUARANTY, THE OTHER CREDIT DOCUMENTS TO WHICH SUCH GUARANTOR IS A PARTY OR
THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

          17. RELEASE OF LIABILITY OF GUARANTOR UPON SALE OR DISSOLUTION. In the
event that all of the capital stock or other Equity Interests of one or more
Guarantors is sold or otherwise disposed of or liquidated in compliance with the
requirements of the Credit Agreement (or such sale, other disposition or
liquidation has been approved in writing by the Required Lenders (or all the
Lenders if required by Section 13.12 of the Credit Agreement)) and the proceeds
of such sale, disposition or liquidation are applied in accordance with the
provisions of the Credit Agreement, to the extent applicable, such Guarantor
shall, upon consummation of such sale or other disposition (except to the extent
that such sale or disposition is to Holdings or any of its Wholly-Owned Domestic
Subsidiaries), be released from this Guaranty automatically and without further
action and this Guaranty shall, as to each such Guarantor or Guarantors,
terminate, and have no further force or effect (it being understood and agreed
that the sale of one or more Persons that own, directly or indirectly, all of
the capital stock or other Equity Interests of any Guarantor shall be deemed to
be a sale of such Guarantor for the purposes of this Section 17).

          18. CONTRIBUTION. At any time a payment in respect of the Guaranteed
Obligations is made under this Guaranty, the right of contribution of each
Guarantor against each

other Guarantor shall be determined as provided in the immediately following
sentence, with the right of contribution of each Guarantor to be revised and
restated as of each date on which a payment (a "Relevant Payment") is made on
the Guaranteed Obligations under this Guaranty. At any time that a Relevant
Payment is made by a Guarantor that results in the aggregate payments made by
such Guarantor in respect of the Guaranteed Obligations to and including the
date of the Relevant Payment exceeding such Guarantor's Contribution Percentage
(as defined below) of the aggregate payments made by all Guarantors in respect
of the Guaranteed Obligations to and including the date of the Relevant Payment
(such excess, the "Aggregate Excess Amount"), each such Guarantor shall have a
right of contribution against each other Guarantor who has made payments in
respect of the Guaranteed Obligations to and including the date of the Relevant
Payment in an aggregate amount less than such other Guarantor's Contribution
Percentage of the aggregate payments made to and including the date of the
Relevant Payment by all Guarantors in respect of the Guaranteed Obligations (the
aggregate amount of such deficit, the "Aggregate Deficit Amount") in an amount
equal to (x) a fraction the numerator of which is the Aggregate Excess Amount of
such Guarantor and the denominator of which is the Aggregate Excess Amount of
all Guarantors multiplied by (y) the Aggregate Deficit Amount of such other
Guarantor. A Guarantor's right of contribution pursuant to the preceding
sentences shall arise at the time of each computation, subject to adjustment to
the time of each computation; provided that no Guarantor may take any action to
enforce such right until the Guaranteed Obligations have been irrevocably paid
in full in cash and the Total Commitment and all Letters of Credit have been
terminated, it being expressly recognized and agreed by all parties hereto that
any Guarantor's right of contribution arising pursuant to this Section 18
against any other Guarantor shall be expressly junior and subordinate to such
other Guarantor's obligations and liabilities in respect of the Guaranteed
Obligations and any other obligations owing under this Guaranty. As used in this
Section 18: (i) each Guarantor's "Contribution Percentage" shall mean the
percentage obtained by dividing (x) the Adjusted Net Worth (as defined below) of
such Guarantor by (y) the aggregate Adjusted Net Worth of all Guarantors; (ii)
the "Adjusted Net Worth" of each Guarantor shall mean the greater of (x) the Net
Worth (as defined below) of such Guarantor and (y) zero; and (iii) the "Net
Worth" of each Guarantor shall mean the amount by which the fair saleable value
of such Guarantor's assets on the date of any Relevant Payment exceeds its
existing debts and other liabilities (including contingent liabilities, but
without giving effect to any Guaranteed Obligations arising under this Guaranty
or any guaranteed obligations arising under any guaranty of the Senior Notes or
Senior Subordinated Notes) on such date. Notwithstanding anything to the
contrary contained above, any Guarantor that is released from this Guaranty
pursuant to Section 17 hereof shall thereafter have no contribution obligations,
or rights, pursuant to this Section 18, and at the time of any such release, if
the released Guarantor had an Aggregate Excess Amount or an Aggregate Deficit
Amount, same shall be deemed reduced to $0, and the contribution rights and
obligations of the remaining Guarantors shall be recalculated on the respective
date of release (as otherwise provided above) based on the payments made
hereunder by the remaining Guarantors. All parties hereto recognize and agree
that, except for any right of contribution arising pursuant to this Section 18,
each Guarantor who makes any payment in respect of the Guaranteed Obligations
shall have no right of contribution or subrogation against any other Guarantor
in respect of such payment until all of the Guaranteed Obligations have been
irrevocably paid in full in cash. Each of the Guarantors recognizes and
acknowledges that the rights to contribution

arising hereunder shall constitute an asset in favor of the party entitled to
such contribution. In this connection, each Guarantor has the right to waive its
contribution right against any Guarantor to the extent that after giving effect
to such waiver such Guarantor would remain solvent, in the determination of the
Required Lenders.

          19. LIMITATION ON GUARANTEED OBLIGATIONS. Each Guarantor and each
Secured Creditor (by its acceptance of the benefits of this Guaranty) hereby
confirms that it is its intention that this Guaranty not constitute a fraudulent
transfer or conveyance for purposes of the Bankruptcy Code, the Uniform
Fraudulent Conveyance Act of any similar Federal or state law. To effectuate the
foregoing intention, each Guarantor and each Secured Creditor (by its acceptance
of the benefits of this Guaranty) hereby irrevocably agrees that the Guaranteed
Obligations guaranteed by such Guarantor shall be limited to such amount as
will, after giving effect to such maximum amount and all other (contingent or
otherwise) liabilities of such Guarantor that are relevant under such laws (it
being understood that it is the intention of the parties to this Guaranty and
the parties to any guaranty of the Senior Subordinated Notes that, to the
maximum extent permitted under applicable laws, the liabilities in respect of
the guarantees of the Senior Subordinated Notes shall not be included for the
foregoing purposes and that, if any reduction is required to the amount
guaranteed by any Guarantor hereunder and with respect to the Senior
Subordinated Notes that its guarantee of amounts owing in respect of the Senior
Subordinated Notes shall first be reduced) and after giving effect to any rights
to contribution pursuant to any agreement providing for an equitable
contribution among such Guarantor and the other Guarantors, result in the
Guaranteed Obligations of such Guarantor in respect of such maximum amount not
constituting a fraudulent transfer or conveyance. Notwithstanding the provisions
of the two preceding sentences, as between the Secured Creditors and the holders
of the Senior Subordinated Notes, it is agreed (and the provisions of the Senior
Subordinated Note Indenture so provide) that any diminution (whether pursuant to
court decree or otherwise) of any Guarantor's obligation to make any
distribution or payment pursuant to this Guaranty shall have no force or effect
for purposes of the subordination provisions contained in the Senior
Subordinated Note Indenture, as applicable, and that any payments received in
respect of a Guarantor's obligations with respect to the Senior Subordinated
Notes, as the case may be, shall be turned over to the holders of the Guarantor
Senior Debt (as defined in each case in the Senior Subordinated Note Indenture)
(or obligations which would have constituted Guarantor Senior Debt if same had
not been reduced or disallowed) of such Guarantor (which Guarantor Senior Debt
shall be calculated as if there were no diminution thereto pursuant to this
Section 19 or for any other reason other than the irrevocable payment in full in
cash of the respective obligations which would otherwise have constituted
Guarantor Senior Debt) until all such Guarantor Senior Debt (or obligations
which would have constituted Guarantor Senior Debt if same had not been reduced
or disallowed) has been irrevocably paid in full in cash.

          20. COUNTERPARTS. This Guaranty may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which when so executed and delivered shall be an original, but all of which
shall together constitute one and the same instrument. A set of counterparts
executed by all the parties hereto shall be lodged with the U.S. Borrower and
the Administrative Agent.

          21. PAYMENTS. (a) All payments made by any Guarantor hereunder will be
made without setoff, counterclaim or other defense, will be made in the relevant
Applicable Currency in which the respective Guaranteed Obligations are owing and
will be made on the same basis as payments are made by the Borrowers under
Sections 5.03 and 5.04 of the Credit Agreement and in accordance with the
following provisions of this Section.

          (b) The Guarantors obligations hereunder to make payments in the
respective Applicable Currency (such Applicable Currency being herein called the
"Obligation Currency") shall not be discharged or satisfied by any tender or
recovery pursuant to any judgment expressed in or converted into any currency
other than the Obligation Currency, except to the extent that such tender or
recovery results in the effective receipt by the Administrative Agent, the
Collateral Agent or the respective other Secured Creditor of the full amount of
the Obligation Currency expressed to be payable to the Administrative Agent, the
Collateral Agent or such other Secured Creditor under this Guaranty or the other
Credit Documents or any Swap Agreement, as applicable. If for the purpose of
obtaining or enforcing judgment against any Guarantor in any court or in any
jurisdiction, it becomes necessary to convert into or from any currency other
than the Obligation Currency (such other currency being hereinafter referred to
as the "Judgment Currency") an amount due in the Obligation Currency, the
conversion shall be made, at the U.S. Dollar Equivalent thereof, as the case may
be, or, in the case of conversion into other currencies, at the rate of exchange
(as quoted by the Administrative Agent or if the Administrative Agent does not
quote a rate of exchange on such currency, by a known dealer in such currency
designated by the Administrative Agent) determined, in each case, as of the date
immediately preceding the day on which the judgment is given (such day being
hereinafter referred to as the "Judgment Currency Conversion Date").

          (c) If there is a change in the rate of exchange prevailing between
the Judgment Currency Conversion Date and the date of actual payment of the
amount due, the Guarantors jointly and severally covenant and agree to pay, or
cause to be paid, such additional amounts, if any (but in any event not a lesser
amount), as may be necessary to ensure that the amount paid in the Judgment
Currency, when converted at the rate of exchange prevailing on the date of
payment, will produce the amount of the Obligation Currency which could have
been purchased with the amount of Judgment Currency stipulated in the judgment
or judicial award at the rate of exchange prevailing on the Judgment Currency
Conversion Date.

          (d) For purposes of determining the U.S. Dollar Equivalent or any
other rate of exchange for this Section 21, such amounts shall include any
premium and costs payable in connection with the purchase of the Obligation
Currency.

          22. ADDITIONAL GUARANTORS. It is understood and agreed that any
Subsidiary of Holdings that is required to execute a counterpart of this
Guaranty after the date hereof pursuant to the Credit Agreement shall become a
Guarantor hereunder by (x) executing and delivering a counterpart hereof to the
Administrative Agent or (y) executing an assumption agreement and delivering
same to the Administrative Agent, in each case as may be requested by (and in
form and substance reasonably satisfactory to) the Administrative Agent and (z)
taking all actions as specified in this Guaranty as would have been taken by
such Guarantor had it been

an original party to this Guaranty, in each case with all documents and actions
required to be taken to be taken above to the reasonable satisfaction of the
Administrative Agent.

          23. HEADINGS DESCRIPTIVE. The headings of the several Sections of this
Guaranty are inserted for convenience only and shall not in any way affect the
meaning or construction of any provision of this Guaranty.

          NOW, THEREFORE, in consideration of the mutual promises contained
herein and other good and valuable consideration, the receipt and sufficiency of
which is hereby acknowledged by the parties hereto, the Parties and the
Collateral Agent (for the benefit of the Senior Creditors) hereby agree as
follows:

          1. The Subordinated Debt (as defined in Section 7 hereof) and all
payments of principal, interest, and all other amounts thereunder are hereby,
and shall continue to be, subject and subordinate in right of payment to the
prior payment in full, in cash, of all Senior Indebtedness to the extent, and in
the manner set forth herein. The foregoing shall apply,

                                       2

notwithstanding the availability of other collateral to the Senior Creditors or
the holders of Subordinated Debt or the actual date and time of execution,
delivery, recordation, filing or perfection of any security interests granted
with respect to the Senior Indebtedness or the Subordinated Debt, or the lien or
priority of payment thereof, and in any instance wherein the Senior Indebtedness
or any claim for the Senior Indebtedness is subordinated, avoided or disallowed,
in whole or in part, under the Bankruptcy Code or other applicable federal,
foreign, state or local law. In the event of a proceeding, whether voluntary or
involuntary, for insolvency, liquidation, reorganization, dissolution,
bankruptcy or other similar proceeding pursuant to the Bankruptcy Code or other
applicable federal, foreign, state or local law (each, a "Bankruptcy
Proceeding"), the Senior Indebtedness shall include all interest accrued on the
Senior Indebtedness, in accordance with and at the rates specified in the Senior
Indebtedness, both for periods before and for periods after the commencement of
any of such proceedings, even if the claim for such interest is not allowed
pursuant to the Bankruptcy Code or other applicable law.

          2. Each Party (as a lender of any Subordinated Debt) hereby agrees
that until all Senior Indebtedness has been repaid in full in cash:

          (a) Such Party shall not, without the prior written consent of the
     Required Senior Creditors (as defined in Section 7 hereof), which consent
     may be withheld or conditioned in the Required Senior Creditors' sole
     discretion, commence, or join or participate in, any Enforcement Action (as
     defined in Section 7 hereof).

          (b) In the event that (i) all or any portion of any Senior
     Indebtedness becomes due (whether at stated maturity, by acceleration or
     otherwise), (ii) any Event of Default under the Credit Agreement or any
     event of default under, and as defined in, any other Senior Indebtedness
     (or the documentation governing the same), then exists or would result from
     such payment on the Subordinated Debt (including, without limitation,
     pursuant to Section 10.08 of the Credit Agreement) (unless cured or waived)
     or (iii) any distribution, division or application, partial or complete,
     voluntary or involuntary, by operation of law or otherwise, is made of all
     or any part of the property, assets or business of Holdings or any of its
     Subsidiaries or the proceeds thereof, in whatever form, to any creditor or
     creditors of Holdings or any of its Subsidiaries or to any holder of
     indebtedness of Holdings or any of its Subsidiaries by reason of any
     liquidation, dissolution or other winding up of Holdings, any of its
     Subsidiaries or their respective businesses, or by reason of any
     receivership or custodianship for Holdings or any of its Subsidiaries or of
     all or substantially all of their respective property, or by reason of any
     insolvency or bankruptcy proceedings or assignment for the benefit of
     creditors or any proceeding by or against Holdings or any of its
     Subsidiaries for any relief under any bankruptcy, reorganization or
     insolvency law or laws, federal, foreign, state or local, or any law,
     federal, foreign, state or local relating to the relief of debtors,
     readjustment of indebtedness, reorganization, composition or extension,
     then, and in any such event, any payment or distribution of any kind or
     character, whether in cash, property or securities which shall be payable
     or deliverable with respect to any or all of the Subordinated Debt or which
     has been received by any Party shall be held in trust by such Party for the
     benefit of the Senior Creditors and shall forthwith be paid or delivered
     directly to the Senior Creditors for application to the payment of the
     Senior Indebtedness (after giving effect to the relative priorities of such
     Senior Indebtedness) to the extent necessary to

                                       3

     make payment in full in cash of all sums due under the Senior Indebtedness
     remaining unpaid after giving effect to any concurrent payment or
     distribution to the Senior Creditors. In any such event, the Senior
     Creditors may, but shall not be obligated to, demand, claim and collect any
     such payment or distribution that would, but for these subordination
     provisions, be payable or deliverable with respect to the Subordinated
     Debt. In the event of the occurrence of any event referred to in subclauses
     (i), (ii) or (iii) of the preceding sentence of this clause (b) above and
     until the Senior Indebtedness shall have been fully paid in cash and
     satisfied and all of the obligations of Holdings or any of its Subsidiaries
     to the Senior Creditors have been performed in full, no payment of any kind
     or character (whether in cash, property, securities or otherwise) shall be
     made to or accepted by any Party in respect of the Subordinated Debt.
     Notwithstanding anything to the contrary contained above, if one or more of
     the events referred to in subclauses (i) through (iii) of the first
     sentence of this clause (b) is in existence, the Required Senior Creditors
     may agree in writing that payments may be made with respect to the
     Subordinated Debt which would otherwise be prohibited pursuant to the
     provisions contained above, provided that any such waiver shall be
     specifically limited to the respective payment or payments which the
     Required Senior Creditors agree may be so paid to any Party in respect of
     the Subordinated Debt.

          (c) If such Party shall acquire by indemnification, subrogation or
     otherwise, any lien, estate, right or other interest in any of the assets
     or properties of Holdings or any of its Subsidiaries, that lien, estate,
     right or other interest shall be subordinate in right of payment to the
     Senior Indebtedness and the lien of the Senior Indebtedness as provided
     herein, and such Party hereby waives any and all rights it may acquire by
     subrogation or otherwise to any lien of the Senior Indebtedness or any
     portion thereof until such time as all Senior Indebtedness has been repaid
     in full in cash.

          (d) Such Party shall not pledge, assign, hypothecate, transfer, convey
     or sell any Subordinated Debt or any interest in any Subordinated Debt to
     any entity (other than in accordance with the relevant requirements of the
     Credit Agreement to a Credit Party which is a Party hereto) without the
     prior written consent of the Administrative Agent (with the prior written
     consent of the Required Senior Creditors).

          (e) After request by the Administrative Agent or the Required Senior
     Creditors, such Party shall promptly furnish the Senior Creditors with a
     statement, duly acknowledged and certified setting forth the original
     principal amount of the notes evidencing the indebtedness of the
     Subordinated Debt, the unpaid principal balance, all accrued but unpaid
     interest and any other sums due and owing thereunder, the rate of interest,
     the monthly payments and that, to the best knowledge of such Party, there
     exists no defaults under the Subordinated Debt, or if any such defaults
     exist, specifying the defaults and the nature thereof.

          (f) In any case commenced by or against Holdings or any of its
     Subsidiaries or under Chapter 11 of the Bankruptcy Code or any similar
     provision thereof, or any similar federal, foreign, state or local statute
     (a "Reorganization Proceeding"), to the extent permitted by applicable law,
     the Required Senior Creditors shall have the

                                       4

     exclusive right to exercise any voting rights in respect of the claims of
     such Party against Holdings or any of its Subsidiaries.

          (g) If, at any time, all or part of any payment with respect to Senior
     Indebtedness theretofore made (whether by Holdings, either Borrower or any
     other Person or enforcement of any right of setoff or otherwise) is
     rescinded or must otherwise be returned by the holders of Senior
     Indebtedness for any reason whatsoever (including, without limitation, the
     insolvency, bankruptcy or reorganization of Holdings, either Borrower or
     such other Persons), the subordination provisions set forth herein shall
     continue to be effective or be reinstated, as the case may be, all as
     though such payment had not been made.

          (h) Such Party shall not object to the entry of any order or orders
     approving any cash collateral stipulations, adequate protection
     stipulations or similar stipulations executed by the Senior Creditors in
     any Reorganization Proceeding or any other proceeding under the Bankruptcy
     Code.

          (i) Such Party waives any marshalling rights with respect to the
     Senior Creditors in any Reorganization Proceeding or any other proceeding
     under the Bankruptcy Code.

          3. Each Party hereby represents, warrants and covenants as follows:

          (a) each Party hereby agrees to deliver a schedule setting forth all
     Intercompany Debt to the Administrative Agent promptly after any request by
     the Administrative Agent or the Required Senior Creditors (although any
     failure to deliver such a supplement shall have no effect whatsoever on the
     subordination provisions contained herein, which shall apply to all
     Subordinated Debt whether or not listed on said schedule); and

          (b) each Party hereby covenants and agrees that it will not lend, hold
     or permit to exist any Intercompany Debt owed by it or to it (in accordance
     with the definition thereof contained herein) unless each obligee, or
     obligor, as the case may be, with respect to such Intercompany Debt is (or
     concurrently with such extension becomes) a Party to this Agreement.

          4. Any payments made to, or received by, any Party in respect of any
guaranty or security in support of the Subordinated Debt shall be subject to the
terms of this Agreement and applied on the same basis as payments made directly
by the obligor under such Subordinated Debt. To the extent that Holdings or any
of its Subsidiaries (other than the respective obligor or obligors which are
already Parties hereto) provides a guaranty or any security in support of any
Subordinated Debt, the Party which is the lender of the respective Subordinated
Debt will cause each such Person to become a Party hereto (if such Person is not
already a Party hereto) not later than the date of the execution and delivery of
the respective guarantee or security documentation, provided that any failure to
comply with the foregoing requirements of this Section 4 will have no effect
whatsoever on the subordination provisions contained herein (which shall apply
to all payments received with respect to any guarantee or

                                       5

security for any Subordinated Debt, whether or not the Person furnishings such
guarantee or security is a Party hereto).

          5. Each Party hereby acknowledges and agrees that no payments will be
accepted by it in respect of the Subordinated Debt (unless promptly turned over
to the holders of Senior Indebtedness) to the extent such payments would be
prohibited under any Senior Indebtedness (or the documentation governing the
same).

          6. In addition to the foregoing agreements, each Party hereby
acknowledges and agrees that, with respect to all Intercompany Debt (whether or
not same constitutes Subordinated Debt), that (x) such Intercompany Debt (and
any promissory notes or other instruments evidencing same) may be pledged, and
delivered for pledge, by Holdings or any of its Subsidiaries pursuant to any
Security Document (as used herein, the term "Security Documents" shall have the
meaning provided in the Credit Agreement) to which Holdings or the respective
such Subsidiary is, or at any time in the future becomes, a party and (y) with
respect to all Intercompany Debt so pledged, the Collateral Agent shall be
entitled to exercise all rights and remedies with respect to such Intercompany
Debt to the maximum extent provided in the various Security Documents (in
accordance with the terms thereof and subject to the requirements of applicable
law). Furthermore, with respect to all Intercompany Debt at any time owed to
Holdings or any of its Subsidiaries which is a Credit Party, and notwithstanding
anything to the contrary contained in the terms of such Intercompany Debt, each
obligor (including any guarantor) and obligee with respect to such Intercompany
Debt hereby agrees, for the benefit of the holders from time to time of the
Senior Indebtedness, that the Administrative Agent or the Collateral Agent may
at any time, and from time to time, acting on its own or at the request of the
Required Senior Creditors, accelerate the maturity of such Intercompany Debt if
(x) any obligor (including any guarantor) of such Intercompany Debt is subject
to any Bankruptcy Proceeding or (y) if the Lenders shall have exercised any
remedies pursuant to the Credit Agreement as a result of the occurrence of an
Event of Default (including any acceleration of the loans or the termination of
commitments thereunder). Any such acceleration of the maturity of any
Intercompany Debt shall be made by written notice by the Administrative Agent or
Collateral Agent to the obligor on the respective Intercompany Debt; provided
that no such notice shall be required (and the acceleration shall automatically
occur) upon the occurrence of a Bankruptcy Proceeding with respect to the
respective obligor (or any guarantor) of the respective Intercompany Debt or
upon (or following) any acceleration of the maturity of any Loans pursuant to
the Credit Agreement.

          7. Definitions. As and in this Agreement, the terms set forth below
shall have the respective meanings provided below:

               "Credit Document Obligations Termination Date" shall mean the
     first date after the Initial Borrowing Date upon which all Commitments and
     Letters of Credit under the Credit Agreement have terminated and all Credit
     Document Obligations have been paid in full in cash.

               "Enforcement Action" shall mean any acceleration of all or any
     part of the Subordinated Debt, the institution of a Bankruptcy Proceeding
     against Holdings or any of its Subsidiaries, or the taking of any other
     enforcement action (including, without

                                       6

     limitation, the taking of any foreclosure proceeding, the exercise of any
     power of sale, the obtaining of a receiver, the suing on, or otherwise
     taking action to enforce the obligation of Holdings or any of its
     Subsidiaries to pay any amounts relating to any Subordinated Debt, the
     exercising of any banker's lien or rights of set-off or recoupment with
     respect to Subordinated Debt) against Holdings or its Subsidiaries or
     against any asset or property of Holdings or its Subsidiaries to recover
     Subordinated Debt.

               "Intercompany Debt" shall mean any Indebtedness, whether now
     existing or hereinafter incurred, owed by Holdings or any Subsidiary of
     Holdings to Holdings or any other Subsidiary of Holdings.

               "Obligation" shall mean any principal, interest, premium,

     indebtedness (including, without limitation, all interest, fees and other
     charges accruing after the commencement of any bankruptcy, insolvency,
     receivership or similar proceeding at the rate provided in the governing
     documentation therefor, whether or not such interest, fees and charges are
     an allowed claim in such proceeding).

               "Required Senior Creditors" shall mean (i) the Required Lenders
     (or, to the extent required by Section 13.12 of the Credit Agreement, each

     outstanding Senior Indebtedness at all times after the Credit Document
     Obligations Termination Date and prior to the repayment in full, in cash,
     of all outstanding Obligations with respect to Senior Indebtedness.

               "Secured Hedging Agreements" shall have the meaning provided in
     the recitals to this Agreement.

          existing or hereafter incurred under, arising out of or in connection
          with each Credit Document to which it is at any time a party
          (including, without limitation, all such obligations and liabilities
          of each Credit Party under the Credit Agreement (if a party thereto)
          and under each Guaranty (if a party thereto) or under any other
          guarantee by it of obligations pursuant to the Credit Agreement) and
          the due performance and compliance by each Credit Party with the terms
          of each such Credit Document (all such obligations and liabilities
          under this clause (i), except to the extent consisting of obligations
          or indebtedness with respect to

          Credit Party with the terms of each such Secured Hedging Agreement
          (all such obligations and liabilities under this clause (ii) being
          herein collectively called the "Hedging Obligations");

was made in a writing signed by such party, provided that amendments hereto
shall be effective as against the Senior Creditors if executed and delivered by
the Required Senior Creditors at such time.

          17. In case any one or more of the provisions confined in this
Agreement, or any application thereof, shall be invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein, and any other application thereof, shall
not in any way be affected or impaired thereby.

Senior Creditors to serve process in any other manner permitted by law or to
commence legal proceedings or otherwise proceed against each Party in any other
jurisdiction.

          (c) EACH PARTY HEREBY IRREVOCABLY WAIVES ANY OBJECTION WHICH IT MAY
