--------------------------------------------------------------------------------

 

          (b) Anything herein or in any other Guaranteed Document to the
contrary notwithstanding, the maximum liability of each Guarantor hereunder and

contribution established in Section 2.02).
          (c) Each Guarantor agrees that the Guarantor 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 ARTICLE II or
affecting the rights and remedies of any Guaranteed Creditor hereunder.
          (d) Each Guarantor agrees that if the maturity of the Guarantor
Obligations is accelerated by bankruptcy or otherwise, such maturity shall also

satisfied by payment in full in cash, no Letter of Credit shall be outstanding
(except for Letters of Credit secured by cash collateral or one or more Support
Letters of Credit as permitted in Section 2.01(b)(iii) of the Credit Agreement)
and all of the Aggregate Commitments are terminated, notwithstanding that from
time to time during the term of the Credit Agreement, no Guarantor Obligations
may be outstanding.
          (e) No payment made by any Guarantor, any other guarantor or any other
Person or received or collected by any Guaranteed Creditor from any Guarantor,
any other guarantor or any other Person by virtue of any action or proceeding or

modify, reduce, release or otherwise affect the liability of any Guarantor
hereunder which shall, notwithstanding any such payment (other than any payment

its proportionate share of such payment. Each Guarantor’s right of contribution
shall be subject to the terms and conditions of Section 2.03. The provisions of

liable to the Guaranteed Creditors for the full amount guaranteed by such
Guarantor hereunder.

--------------------------------------------------------------------------------

 

against any Borrower or any other Guarantor or any collateral security or
guarantee or right of offset held by any Guaranteed Creditor for the payment of
the Guarantor Obligations, nor shall any Guarantor seek or be entitled to
exercise any right to seek any indemnity, exoneration, participation,
contribution or reimbursement from any Borrower or any other Guarantor in

Credit secured by cash collateral or one or more Support Letters of Credit as
permitted in Section 2.01(b)(iii) of the Credit Agreement) or any of the
Aggregate Commitments are in effect, such amount shall be held by such Guarantor
in trust for the Guaranteed Creditors, and shall, forthwith upon receipt by such
Guarantor, be turned over to the US Administrative Agent in the exact form
received by such Guarantor (duly indorsed by such Guarantor to the US
Administrative Agent, if required), to be applied against the Guarantor
Obligations, whether matured or unmatured, in accordance with Section 11.02(c)
of the Credit Agreement.
     Section 2.04 Amendments, Etc. with respect to the Guarantor Obligations.

notice, demand and assent requirements are hereby expressly waived by such
Guarantor), (a) any demand for payment of any of the Guarantor Obligations made
by any Guaranteed Creditor may be rescinded by such Guaranteed Creditor or
otherwise and any of the Guarantor Obligations continued; (b) the Guarantor

other event shall occur which constitutes a defense or release of sureties

ARTICLE III
Representations and Warranties
     To induce the US 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 Borrowers thereunder and to induce the Guaranteed Creditors to
enter into Hedging Agreements and Treasury Management Agreements with the
Borrowers and their Restricted Subsidiaries (other than any ABS Subsidiary),
each Guarantor hereby represents and warrants to the US Administrative Agent and
each Lender for itself only that:
     Section 3.01 Representations in Credit Agreement. In the case of such
Guarantor, the representations and warranties set forth in Article VII of the
Credit Agreement as they relate to such Guarantor or to the Loan Documents to
which such Guarantor is a party are true and correct in all material respects,
provided that each reference in each such representation and warranty to each
Borrower’s knowledge, as applicable, shall, for the purposes of this Section
3.01, be deemed to be a reference to such Guarantor’s knowledge.
     Section 3.02 Benefit to the Guarantor. The Borrowers are members of an
affiliated group of companies that includes each Guarantor. Each Guarantor is a
Subsidiary of the US Borrower, and its guaranty and surety obligations pursuant
to this Agreement reasonably may be expected to benefit, directly or indirectly,
the Borrowers, and it has determined that this Agreement is necessary and
convenient to the conduct, promotion and attainment of the business of such
Guarantor and the Borrowers.
     Section 3.03 Solvency. Such Guarantor (a) is not insolvent as of the date
hereof and will not be rendered insolvent as a result of this Agreement (after
giving effect to Section 2.02), (b) is not engaged in business or a transaction,
or about to engage in a business or a transaction, for which any Property
remaining with it constitute unreasonably small capital and (c) does not intend
to incur, or believe it will incur, Debt that will be beyond its ability to pay
as such Debt matures.
ARTICLE IV
Covenants
     Each Guarantor covenants and agrees with the US Administrative Agent and
the Lenders for itself only that, from and after the date of this Agreement
until the Guarantor Obligations shall have been paid in full in cash, no Letter
of Credit shall be outstanding (except for Letters of Credit secured by cash
collateral or one or more Support Letters of Credit as permitted in Section

- 8 -

--------------------------------------------------------------------------------

 

2.01(b)(iii) of the Credit Agreement) and all of the Aggregate Commitments shall
have terminated:
     Section 4.01 Covenants in Credit Agreement. In the case of each Guarantor,
such Guarantor shall take, or shall refrain from taking, as the case may be,
each action that is necessary to be taken or not taken, as the case may be, so
that no Default or Event of Default is caused by the failure to take such action
or to refrain from taking such action by such Guarantor or any of its Restricted
Subsidiaries.
ARTICLE V
The US Administrative Agent
     Section 5.01 Authority of US Administrative Agent. Each Guarantor
acknowledges that the rights and responsibilities of the US Administrative Agent
under this Agreement with respect to any action taken by the US Administrative
Agent or the exercise or non-exercise by the US 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 US
Administrative Agent and the Guaranteed Creditors, 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 US Administrative Agent and the
Guarantors, the US Administrative Agent shall be conclusively presumed to be
acting as agent for the Guaranteed Creditors with full and valid authority so to
act or refrain from acting, and no Guarantor shall be under any obligation, or
entitlement, to make any inquiry respecting such authority.
ARTICLE VI
Subordination of Indebtedness
     Section 6.01 Subordination of All Guarantor Claims. As used herein, the
term “Guarantor Claims” shall mean all debts and obligations of the Borrowers or
any other Guarantor to any other Guarantor, whether such debts and obligations
now exist or are hereafter incurred or arise, or whether the obligation of the
debtor thereon be direct, contingent, primary, secondary, several, joint and
several, or otherwise, and irrespective of whether such debts or obligations be
evidenced by note, contract, open account, or otherwise, and irrespective of the
Person or Persons in whose favor such debts or obligations may, at their
inception, have been, or may hereafter be created, or the manner in which they
have been or may hereafter be acquired by. After and during the continuation of
an Event of Default, no Guarantor shall receive or collect, directly or
indirectly, from any obligor in respect thereof any amount upon the Guarantor
Claims.
     Section 6.02 Claims in Bankruptcy. In the event of receivership,
bankruptcy, reorganization, arrangement, debtor’s relief or other insolvency
proceedings involving any Guarantor, the US Administrative Agent on behalf of
the US Administrative Agent and the Guaranteed Creditors shall have the right to
prove their claim in any proceeding, so as to establish their rights hereunder
and receive directly from the receiver, trustee or other court custodian,
dividends and payments which would otherwise be payable upon Guarantor Claims.
Each Guarantor hereby assigns such dividends and payments to the US
Administrative Agent for the benefit of the US Administrative Agent and the
Guaranteed Creditors for application against the Guarantor Obligations as
provided under Section 11.02(b) of the Credit Agreement. Should

--------------------------------------------------------------------------------

 

any Agent or Guaranteed Creditor receive, for application upon the Guarantor
Obligations, any such dividend or payment which is otherwise payable to any
Guarantor, and which, as between such Guarantors, shall constitute a credit upon
the Guarantor Claims, then upon payment in full in cash of the Guarantor
Obligations, the expiration of all Letters of Credit (except for Letters of
Credit secured by cash collateral or one or more Support Letters of Credit as
permitted in Section 2.01(b)(iii) of the Credit Agreement) and the termination
of all of the Aggregate Commitments, the intended recipient shall become
subrogated to the rights of the US Administrative Agent and the Guaranteed
Creditors to the extent that such payments to the US Administrative Agent and
the Lenders on the Guarantor Claims have contributed toward the liquidation of
the Guarantor Obligations, and such subrogation shall be with respect to that
proportion of the Guarantor Obligations which would have been unpaid if the US
Administrative Agent and the Guaranteed Creditors had not received dividends or
payments upon the Guarantor Claims.
     Section 6.03 Payments Held in Trust. In the event that notwithstanding
Section 6.01 and Section 6.02, any Guarantor should receive any funds, payments,
claims or distributions which is prohibited by such Sections, then it agrees:
(a) to hold in trust for the US Administrative Agent and the Guaranteed
Creditors an amount equal to the amount of all funds, payments, claims or
distributions so received, and (b) that it shall have absolutely no dominion
over the amount of such funds, payments, claims or distributions except to pay
them promptly to the US Administrative Agent, for the benefit of the Guaranteed
Creditors; and each Guarantor covenants promptly to pay the same to the US
Administrative Agent.
     Section 6.04 Liens Subordinate. Each Guarantor agrees that, until the
Guarantor Obligations are paid in full in cash, the expiration of all Letters of
Credit (except for Letters of Credit secured by cash collateral or one or more
Support Letters of Credit as permitted in Section 2.01(b)(iii) of the Credit
Agreement) and the termination of all of the Aggregate Commitments, any Liens
securing payment of the Guarantor Claims shall be and remain inferior and
subordinate to any Liens securing payment of the Guarantor Obligations,
regardless of whether such encumbrances in favor of such Guarantor, the US
Administrative Agent or any Guaranteed Creditor presently exist or are hereafter
created or attach. Without the prior written consent of the US Administrative
Agent, no Guarantor, during the period in which any of the Guarantor Obligations
are outstanding, any Letters of Credit are outstanding (except for Letters of
Credit secured by cash collateral or one or more Support Letters of Credit as
permitted in Section 2.01(b)(iii) of the Credit Agreement) or the Aggregate
Commitments are in effect, shall (a) exercise or enforce any creditor’s right it
may have against any debtor in respect of the Guarantor Claims, or
(b) foreclose, repossess, sequester or otherwise take steps or institute any
action or proceeding (judicial or otherwise, including without limitation the
commencement of or joinder in any liquidation, bankruptcy, rearrangement,
debtor’s relief or insolvency proceeding) to enforce any Lien held by it that
secures Guarantors Claims.
     Section 6.05 Notation of Records. Upon the request of the US Administrative
Agent, all promissory notes and all accounts receivable ledgers or other
evidence of the Guarantor Claims accepted by or held by any Guarantor shall
contain a specific written notice thereon that the indebtedness evidenced
thereby is subordinated under the terms of this Agreement.

Miscellaneous
     Section 7.01 Waiver. No failure on the part of the US Administrative Agent
or any Guaranteed Creditor to exercise and no delay in exercising, and no course
of dealing with respect to, any right, power, privilege or remedy or any
abandonment or discontinuance of steps to enforce such right, power, privilege
or remedy under this Agreement or any other Loan Document shall operate as a
waiver thereof, nor shall any single or partial exercise of any right, power,
privilege or remedy under this Agreement or any other Loan Document preclude or
be construed as a waiver of any other or further exercise thereof or the
exercise of any other right, power, privilege or remedy. The remedies provided
herein are cumulative and not exclusive of any remedies provided by law or
equity.
     Section 7.02 Notices. All notices and other communications provided for
herein shall be given in the manner and subject to the terms of Section 13.02 of

upon any Guarantor shall be addressed to such Guarantor at its notice address
set forth on Schedule 1.
     Section 7.03 Amendments in Writing. None of the terms or provisions of this

following sentence, the provisions of this Agreement shall be binding upon the

successors and permitted assigns; provided that no Guarantor may assign,
transfer or delegate any of its rights or obligations under this Agreement
without the prior written consent of the US Administrative Agent and the Lenders
unless otherwise permitted by the terms of the Credit Agreement or this
Agreement, and any such purported assignment, transfer or delegation shall be
null and void. A Guarantor shall automatically cease to be a party hereto, and
shall be released pursuant to Section 9.07(d) of the Credit Agreement from its
obligations hereunder, upon such Guarantor ceasing to be a Significant Domestic
Subsidiary wholly-owned by the US Borrower in accordance with the Credit
Agreement.
     Section 7.05 Survival; Revival; Reinstatement.
          (a) All covenants, agreements, representations and warranties made by
any Guarantor herein and in the certificates or other instruments delivered in
connection with or pursuant to this Agreement or any other Loan Document to
which it is a party shall be considered to have been relied upon by the US
Administrative Agent, the other Agents, the Issuing Bank and the Lenders and
shall survive the execution and delivery of this Agreement and the making of any
Loans and issuance of any Letters of Credit, regardless of any investigation
made by any such other party or on its behalf and notwithstanding that the US
Administrative Agent, the other Agents, the Issuing Bank or any Lender may have
had notice or knowledge of any Default or incorrect representation or warranty
at the time any credit is extended hereunder, and shall continue in full force
and effect as long as the principal of or any accrued interest on

- 11 -

--------------------------------------------------------------------------------

 

any Loan or any fee or any other amount payable under the Credit Agreement is
outstanding and unpaid or any Letter of Credit is outstanding (except for
Letters of Credit secured by cash collateral or one or more Support Letters of
Credit as permitted in Section 2.01(b)(iii) of the Credit Agreement) and so long
as the Aggregate Commitments have not expired or terminated.
          (b) To the extent that any payments on the Guarantor Obligations are
subsequently invalidated, declared to be fraudulent or preferential, set aside
or required to be repaid to a trustee, debtor in possession, receiver or other
Person under any bankruptcy law, common law or equitable cause, then to such
extent, the Guarantor Obligations so satisfied shall be revived and continue as
if such payment or proceeds had not been received and the US Administrative
Agent’s and the Guaranteed Creditors’ Liens, security interests, rights, powers
and remedies under this Agreement and each other Loan Document shall continue in
full force and effect. In such event, each Loan Document shall be automatically
reinstated and the Borrowers shall take such action as may be reasonably
requested by the US Administrative Agent and the Guaranteed Creditors to effect
such reinstatement.
     Section 7.06 Counterparts; Integration; Effectiveness; Conflicts.
          (a) This Agreement may be executed in counterparts (and by different
parties hereto on different counterparts), each of which shall constitute an
original, but all of which when taken together shall constitute a single
contract.
          (b) This Agreement and the other Loan Documents embody the entire
agreement and understanding between the parties and supersede all other
agreements and understandings between such parties relating to the subject

final agreement between the parties and may not be contradicted by evidence of
prior, contemporaneous or subsequent oral agreements of the parties. There are
no unwritten oral agreements between the parties.
          (c) This Agreement shall become effective when it shall have been
executed by the US Administrative Agent and when the US Administrative Agent
shall have received counterparts hereof which, when taken together, bear the
signatures of each of the other parties hereto, and thereafter shall be binding
upon and inure to the benefit of the parties hereto, the Lenders and their
respective successors and assigns. Delivery of an executed counterpart of a
signature page of this Agreement by telecopy shall be effective as delivery of a
manually executed counterpart of this Agreement.
          (d) In the event of a conflict between the provisions hereof and the
provisions of the Credit Agreement, the provisions of the Credit Agreement shall
control.
     Section 7.07 Severability. Any provision of this Agreement or any other
Loan Document held to be invalid, illegal or unenforceable in any jurisdiction
shall, as to such jurisdiction, be ineffective to the extent of such invalidity,
illegality or unenforceability without affecting the validity, legality and
enforceability of the remaining provisions hereof or thereof; and the invalidity
of a particular provision in a particular jurisdiction shall not invalidate such
provision in any other jurisdiction.
