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 Secured Creditors to enter into Hedging Agreements and Treasury Management Agreements with the Borrowers and their Restricted Subsidiaries (other

than any ABS Subsidiary), each Grantor hereby represents and warrants to the US Administrative Agent and each Lender for itself only that:

     Section 3.01 Title; No Other Liens. Except for Permitted Liens and the security interest granted to the US Administrative Agent for the ratable benefit of the Secured Creditors pursuant to this Agreement, such Grantor is the record and beneficial owner of its respective items of the Collateral free and clear of any and all Liens and has the power to transfer each item of the Collateral in which a Lien is granted by it hereunder, free and clear of any Lien. Except with respect to Liens permitted by Section 10.02(b), (c), (e) or (g) of the Credit Agreement, no financing statement or other public notice with respect to all or any part of the Collateral is on file or of record in any public office, except such as have been filed in favor of the US Administrative Agent, for the ratable benefit of the Secured Creditors, pursuant to this Agreement or the Security Instruments or as are filed to secure Liens permitted by Section 10.02 of the Credit Agreement.

     Section 3.02 Perfected First Priority Liens. The security interests granted pursuant to this Agreement (a) upon the completion of the filings and the other actions specified on Schedule 2 constitute valid perfected security interests in all of the Collateral in favor of the US Administrative Agent, for the ratable benefit of the Secured Creditors, as collateral security for the Obligations, enforceable in accordance with the terms hereof against all creditors of such Grantor and any Persons purporting to purchase any Collateral from such Grantor and (b) are prior to all other Liens on the Collateral in existence on the date hereof, except, in each case, for Liens expressly permitted by the Credit Agreement.

     Section 3.03 Grantor Information. On the date hereof, the correct legal name of such Grantor, such Grantor’s jurisdiction of organization and organizational number, and the location(s) of such Grantor’s chief executive office or sole place of business are specified on Schedule 3.

     Section 4.03. No Collateral constituting Chattel Paper or Instruments contains any statement therein to the effect that such Collateral has been assigned to an identified party other than the US Administrative Agent, and the grant of a security interest in such Collateral in favor of the US Administrative Agent hereunder does not violate the rights of any other Person as a secured party.

     Section 3.05 Truth of Information; Accounts. All information with respect to the Collateral set forth in any schedule or certificate at any time heretofore or hereafter furnished by such Grantor to the US Administrative Agent is and will be true and correct in all material respects as of the date furnished. On the date hereof, the place where each Grantor keeps its records concerning the Accounts, Chattel Paper and Payment Intangibles is set forth on Schedule 4.

     Section 4.01 Maintenance of Perfected Security Interest; Further Documentation. Except as set forth in the Credit Agreement, including, without limitation, any merger, consolidation, liquidation, sale, assignment, transfer or other disposition permitted by Section 10.08 or 10.14 of the Credit Agreement, each Grantor agrees that:

          (a) it shall maintain the security interest created by this Agreement as a perfected security interest having at least the priority described in Section 3.02 and shall defend such security interest against the claims and demands of all Persons whomsoever;

          (b) it will furnish to the US Administrative Agent and the Lenders from time to time statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as the US Administrative Agent may reasonably request, all in reasonable detail; provided that upon any Account Debtor that is Governmental Authority having a material portion of all the Grantors’ Accounts, Chattel Paper or Payment Intangibles, taken as a whole, it will promptly furnish such statement to the US Administrative Agent and the Lenders all in reasonable detail, as the US Administrative Agent may reasonably request;

          (c) at any time and from time to time, upon the written request of the US Administrative Agent, and at the sole expense of such Grantor, it will promptly and duly execute and deliver, and have recorded, such further instruments and documents and take such further actions as the US Administrative Agent may reasonably deem necessary for the purpose of obtaining or preserving the full benefits of this Agreement and of the rights and powers herein granted, including, without limitation, the filing of any financing or continuation statements under the UCC (or other similar domestic laws) in effect in any jurisdiction with respect to the security interests created hereby.

     Section 4.02 Changes in Locations, Name, Etc. Such Grantor recognizes that financing statements pertaining to the Collateral have been or may be filed where such Grantor is organized.

interests under this Agreement. In any notice furnished pursuant to this Section 4.02, such Grantor will expressly state in a conspicuous manner that the notice is required by this Agreement and contains facts that may require additional filings of financing statements or other notices for the purposes of continuing perfection of the US Administrative Agent’s security interest in the Collateral.

     Section 4.03 Instruments and Tangible Chattel Paper. If any amount payable under or in connection with any of the Collateral shall be or become evidenced by any Instrument or Tangible Chattel Paper having a value in excess of $5,000,000, such Instrument or Tangible Chattel Paper shall be immediately delivered to the US Administrative Agent, duly endorsed in a manner satisfactory to the US Administrative Agent, to be held as Collateral pursuant to this Agreement.

ARTICLE V
Remedial Provisions

     Section 5.01 UCC and Other Remedies.

          (a) Upon the occurrence and during the continuance of an Event of Default, the US Administrative Agent, on behalf of the Secured Creditors, may exercise, in addition to all other rights and remedies granted to them in this Agreement, the other Loan Documents and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a secured party under the UCC or any other applicable law or otherwise available at law or equity. Without limiting the generality of the foregoing, the US Administrative Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by applicable law) to or upon any Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of any Secured Creditor or elsewhere upon such commercially reasonable terms and conditions as it may deem advisable and at such commercially reasonable prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. Any Secured Creditor shall have the right upon any such public sale or sales, and, to the extent permitted by applicable law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in any Grantor, which right or equity is hereby waived and released. If applicable to any particular item of Collateral, each Grantor further agrees, at the US Administrative Agent’s request following an acceleration of the Indebtedness under Section 11.02(a) of the Credit Agreement, to assemble the Collateral and make it available to the US Administrative Agent at places which the US Administrative Agent shall reasonably select, whether at such Grantor’s premises or elsewhere, unless prohibited by agreements with unaffiliated third parties. Any such sale or transfer by the US Administrative Agent either to itself or to any other Person shall, to the fullest extent permitted under applicable law, be absolutely free from any claim of right by Grantor, including any equity or right of redemption, stay or appraisal which Grantor has or may have under any rule of law, regulation or statute now existing or hereafter adopted (and such

Grantor hereby waives any rights it may have in respect thereof). Upon any such sale or transfer, the US Administrative Agent shall have the right to deliver, assign and transfer to the purchaser or transferee thereof the Collateral so sold or transferred. The US Administrative Agent shall apply the net proceeds of any action taken by it pursuant to this Section 5.01, after deducting all reasonable costs and expenses of every kind incurred in connection therewith or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the US Administrative Agent and the Secured Creditors hereunder, including, without limitation, reasonable attorneys’ fees and disbursements, to the payment in whole or in part of the Obligations, in accordance with the Credit Agreement, and only after such application and after the payment by the US Administrative Agent of any other amount required by any provision of law, including, without limitation, Section 9.615 of the UCC, need the US Administrative Agent account for the surplus, if any, to any Grantor. To the extent permitted by applicable law, each Grantor waives all claims, damages and demands it may acquire against the US Administrative Agent or any Secured Creditor arising out of the exercise by them of any rights hereunder. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least ten (10) days before such sale or other disposition.

          (b) In the event that the US Administrative Agent elects not to sell the Collateral, the US Administrative Agent retains its rights to dispose of or utilize the Collateral or any part or parts thereof in any manner authorized or permitted by law or in equity, and to apply the proceeds of the same towards payment of the Obligations. Each and every method of disposition of the Collateral described in this Agreement shall constitute disposition in a commercially reasonable manner.

          (c) The US Administrative Agent may appoint any Person as agent to perform any act or acts necessary or incident to any sale or transfer of the Collateral.

     Section 5.02 Collections on Accounts, Etc. The US Administrative Agent hereby authorizes each Grantor to collect upon the Collateral that is represented by Accounts, Instruments, Chattel Paper and Payment Intangibles subject to the US Administrative Agent’s direction and control, and the US Administrative Agent may curtail or terminate said authority at any time after the occurrence and during the continuance of an Event of Default. Upon the request of the US Administrative Agent at any time after the occurrence and during the continuance of an Event of Default, each Grantor shall notify the Account Debtors that the applicable Accounts, Chattel Paper and Payment Intangibles have been assigned to the US Administrative Agent for the ratable benefit of the Secured Creditors and that payments in respect thereof shall be made directly to the US Administrative Agent. The US Administrative Agent may in its own name or in the name of others communicate with the Account Debtors to verify with them to its satisfaction the existence, amount and terms of any such Accounts, Chattel Paper or Payment Intangibles. Anything herein to the contrary notwithstanding, each Grantor shall remain liable under each of its Accounts to observe and perform all the conditions and obligations to be observed and performed by it thereunder, all in accordance with the terms of any agreement giving rise thereto. Neither the US Administrative Agent nor any Lender shall have any obligation or liability under any Account (or any agreement giving rise thereto) by reason of or arising out of this Agreement or the receipt by the US Administrative Agent or any Lender of any payment relating thereto, nor shall the US Administrative Agent or any Lender be

obligated in any manner to perform any of the obligations of any Grantor under or pursuant to any Account (or any agreement giving rise thereto) to make any payment, to make any inquiry as to the nature or the sufficiency of any payment received by it or as to the sufficiency of any performance by any party thereunder, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times.

     Section 5.03 Proceeds. If required by the US Administrative Agent at any time after the occurrence and during the continuance of an Event of Default, any payments of Collateral composed of Accounts, Instruments, Chattel Paper and Payment Intangibles, when collected or received by each Grantor, and any other cash or non-cash Proceeds received by each Grantor upon the sale or other disposition of any Collateral, shall be forthwith (and, in any event, within two Business Days) deposited by such Grantor in the exact form received, duly indorsed by such Grantor to the US Administrative Agent if required, in a special collateral account maintained by the US Administrative Agent, subject to withdrawal by the US Administrative Agent for the ratable benefit of the Secured Parties only, as hereinafter provided, and, until so turned over, shall be held by such Grantor in trust for the US Administrative Agent for the ratable benefit of the Secured Creditors, segregated from other funds of any such Grantor. Each deposit of any such Proceeds shall be accompanied by a report identifying in reasonable detail the nature and source of the payments included in the deposit. All Proceeds (including, without limitation, Proceeds constituting collections of Accounts, Chattel Paper, Instruments) while held by the US Administrative Agent (or by any Grantor in trust for the US Administrative Agent for the ratable benefit of the Secured Creditors) shall continue to be collateral security for all of the Obligations and shall not constitute payment thereof until applied as hereinafter provided. At such intervals as may be agreed upon by each Grantor and the US Administrative Agent, or, if an Event of Default shall have occurred and be continuing, at any time at the US Administrative Agent’s election, the US Administrative Agent shall apply all or any part of the funds on deposit in said special collateral account on account of the Obligations in such order as the US Administrative Agent may elect, and any part of such funds which the US Administrative Agent elects not so to apply and deems not required as collateral security for the Obligations shall be paid over from time to time by the US Administrative Agent to each Grantor or to whomsoever may be lawfully entitled to receive the same.

     Section 5.04 Deficiency. Each Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay its obligations and the fees and disbursements of any attorneys employed by the US Administrative Agent or any Secured Creditor to collect such deficiency.

     Section 5.05 Non-Judicial Enforcement. The US Administrative Agent may enforce its rights hereunder without prior judicial process or judicial hearing, and to the extent permitted by law, each Grantor expressly waives any and all legal rights which might otherwise require the US Administrative Agent to enforce its rights by judicial process.

ARTICLE VI
The US Administrative Agent

     Section 6.01 US Administrative Agent’s Appointment as Attorney-in-Fact, Etc.

          (a) Anything in this Section 6.01(a) to the contrary notwithstanding, the US Administrative Agent agrees that it will not exercise any rights under the power of attorney provided for in this Section 6.01(a) unless an Event of Default shall have occurred and be continuing. Each Grantor hereby irrevocably constitutes and appoints the US Administrative Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of such Grantor and in the name of such Grantor or in its own name, for the purpose of carrying out the terms of this Agreement, to take any and all reasonably appropriate action and to execute any and all documents and instruments which may be reasonably necessary or desirable to accomplish the purposes of this Agreement, and, without limiting the generality of the foregoing, each Grantor hereby gives the US Administrative Agent the power and right, on behalf of such Grantor, without notice to or assent by such Grantor, to do any or all of the following:

               (i) unless being disputed under Section 9.03(a) of the Credit Agreement, pay or discharge Taxes and Liens levied or placed on or threatened against the Collateral, effect any repairs or any insurance called for by the terms of this Agreement or any other Loan Document and pay all or any part of the premiums therefor and the costs thereof; and

               (ii) (A) direct any party liable for any payment under any of the Collateral to make payment of any and all moneys due or to become due thereunder directly to the US Administrative Agent or as the US Administrative Agent shall direct; (B) ask or demand for, collect, and receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral; (C) in the name of such Grantor or its own name, or otherwise, take possession of and indorse and collect any check, draft, note, acceptance or other instrument for the payment of moneys due with respect to any Collateral and commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any portion thereof and to enforce any other right in respect of any Collateral; (D) defend any suit, action or proceeding brought against such Grantor with respect to any Collateral; (E) settle, compromise or adjust any such suit, action or proceeding and, in connection therewith, give such discharges or releases as the US Administrative Agent may deem appropriate; and (F) generally, sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the US Administrative Agent were the absolute owner thereof for all purposes, and do, at the US Administrative Agent’s option and such Grantor’s expense, at any time, or from time to time, all acts and things which the US Administrative Agent deems necessary to protect, preserve or realize upon the Collateral and the US Administrative Agent’s and the Secured Creditors’ security interests therein and to effect the intent of this Agreement, all as fully and effectively as such Grantor might do.

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

          (c) The reasonable expenses of the US Administrative Agent incurred in connection with actions undertaken as provided in this Section 6.01, together with interest thereon at a rate per annum equal to the Post-Default Rate, but in no event to exceed the Highest Lawful Rate, from the date of payment by the US Administrative Agent to the date reimbursed by the relevant Grantor, shall be payable by such Grantor to the US Administrative Agent on demand.

          (d) All powers, authorizations and agencies contained in this Agreement are coupled with an interest and are irrevocable until this Agreement is terminated and the security interests created hereby are released.

     Section 6.02 Duty of US Administrative Agent. The US Administrative Agent’s sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9.207 of the UCC or otherwise, shall be to deal with it in the same manner as the US Administrative Agent deals with similar Property for its own account and shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which comparable secured parties accord comparable collateral. To the fullest extent permitted under applicable law, neither the US Administrative Agent, any Secured Creditor nor any of their respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The powers conferred on the US Administrative Agent and the Secured Creditors hereunder are solely to protect the US Administrative Agent’s and the Secured Creditors’ interests in the Collateral and shall not impose any duty upon the US Administrative Agent or any Secured Creditor to exercise any such powers. The US Administrative Agent and the Secured Creditors shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers, directors, employees or agents shall be responsible to any Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct. To the fullest extent permitted by applicable law, the US Administrative Agent shall be under no duty whatsoever to make or give any presentment, notice of dishonor, protest, demand for performance, notice of non-performance, notice of intent to accelerate, notice of acceleration or other notice or demand in connection with any Collateral or the Obligations, or to take any steps necessary to preserve any rights against any Grantor or other Person or ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not it has or is deemed to have knowledge of such matters. Each Grantor, to the extent permitted by applicable law, waives any right of marshaling in respect of any and all Collateral, and waives any right to require the US Administrative Agent or any Secured Creditor to proceed against any Grantor or other Person, exhaust any Collateral or enforce any other remedy which the US Administrative Agent or any Secured Creditor now has or may hereafter have against each Grantor, any Grantor or other Person.

     Section 6.03 Filing of Financing Statements. Pursuant to the UCC and any other applicable law, each Grantor authorizes the US Administrative Agent to file or record financing statements and other filing or recording documents or instruments with respect to the Collateral

in such form and in such offices as the US Administrative Agent reasonably determines appropriate to perfect the security interests of the US Administrative Agent under this Agreement. A photographic or other reproduction of this Agreement shall be sufficient as a financing statement or other filing or recording document or instrument for filing or recording in any jurisdiction.

     Section 6.04 Authority of US Administrative Agent. Each Grantor 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 Secured 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 Grantors, the US Administrative Agent shall be conclusively presumed to be acting as agent for the Secured Creditors with full and valid authority so to act or refrain from acting, and no Grantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

ARTICLE VII
Subordination of Indebtedness

     Section 7.01 Subordination of All Grantor Claims. As used herein, the term “Grantor Claims” shall mean all debts and obligations of the Borrowers or any other Grantor to any other Grantor, 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. Except for payments permitted by the Credit Agreement, after and during the continuation of an Event of Default, no Grantor shall receive or collect, directly or indirectly, from any obligor in respect thereof any amount upon the Grantor Claims.

     Section 7.02 Claims in Bankruptcy. In the event of receivership, bankruptcy, reorganization, arrangement, debtor’s relief or other insolvency proceedings involving any Grantor, the US Administrative Agent on behalf of the US Administrative Agent and the Secured 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 Grantor Claims. Each Grantor hereby assigns such dividends and payments to the US Administrative Agent for the benefit of the US Administrative Agent and the Secured Creditors for application against the Obligations as provided under the Credit Agreement. Should any Agent or Secured Creditor receive, for application upon the Obligations, any such dividend or payment which is otherwise payable to any Grantor, and which, as between such Grantors, shall constitute a credit upon the Grantor Claims, then upon payment in full in cash of the Obligations, the expiration of all Letters of Credit outstanding under the Credit Agreement (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 Secured Creditors to the extent that such payments to the US Administrative Agent and the Lenders on the Grantor Claims have contributed toward the liquidation of the Obligations, and such subrogation shall be with respect to that proportion of the Obligations which would have been unpaid if the US Administrative Agent and the Secured Creditors had not received dividends or payments upon the Grantor Claims.

     Section 7.03 Payments Held in Trust. In the event that notwithstanding Section 7.01 and Section 7.02, any Grantor 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 Secured 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 Secured Creditors; and each Grantor covenants promptly to pay the same to the US Administrative Agent.

     Section 7.04 Liens Subordinate. Each Grantor agrees that, until the Obligations are 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 2.01(b)(iii) of the Credit Agreement) and the termination of all of the Aggregate Commitments, any Liens securing payment of the Grantor Claims shall be and remain inferior and subordinate to any Liens securing payment of the Obligations, regardless of whether such encumbrances in favor of such Grantor, the US Administrative Agent or any Secured Creditor presently exist or are hereafter created or attach. Without the prior written consent of the US Administrative Agent, no Grantor, during the period in which any of the Obligations are outstanding 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 Grantor 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 Grantor Claims.

     Section 7.05 Notation of Records. Upon the request of the US Administrative Agent, all promissory notes and all accounts receivable ledgers or other evidence of the Grantor Claims accepted by or held by any Grantor shall contain a specific written notice thereon that the indebtedness evidenced thereby is subordinated under the terms of this Agreement.

ARTICLE VIII
Miscellaneous

     Section 8.01 Waiver. No failure on the part of the US Administrative Agent or any Secured 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 8.02 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 the Credit Agreement; provided that any such notice, request or demand to or upon any Grantor shall be addressed to such Grantor at its notice address set forth on Schedule 1.

          (a) All covenants, agreements, representations and warranties made by any Grantor 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 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 Obligations or proceeds of any Collateral 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 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 Secured 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 Grantors

shall take such action as may be reasonably requested by the US Administrative Agent and the Secured Creditors to effect such reinstatement.

     Section 8.06 Counterparts; Integration; Effectiveness; Conflicts.

          (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.

     Section 8.08 Governing Law; Submission to Jurisdiction.

          (a) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS.

          (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF TEXAS OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF TEXAS IN HOUSTON, TEXAS, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH OF THE PARTIES HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT PERMITTED BY LAW) IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS.

          (c) EACH GRANTOR IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS 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 SUCH GRANTOR AT ITS ADDRESS SET FORTH ON SCHEDULE 1 HERETO OR AS UPDATED FROM TIME TO TIME, SUCH SERVICE TO BECOME EFFECTIVE THIRTY (30) DAYS AFTER SUCH MAILING.

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

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

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

EACH PARTY HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION OF THIS AGREEMENT AND THE SECURITY INSTRUMENTS ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT “CONSPICUOUS.”

     Section 8.11 Additional Grantor. Each Subsidiary that is required to become a party to this Agreement pursuant to Section 9.07(a) of the Credit Agreement shall become a Grantor for all purposes of this Agreement upon execution and delivery by such Subsidiary of a Supplement in the form of Annex I hereto and shall thereafter have the same rights, benefits and obligations as a Grantor party hereto on the date hereof.

     Section 8.12 Releases.

          (a) Full Release. The grant of a security interest hereunder and all of rights, powers and remedies in connection herewith shall remain in full force and effect until the US Administrative Agent has (i) retransferred and delivered all Collateral in its possession to the Grantors and (ii) executed a written release or termination statement and reassigned to the Grantors without recourse or warranty any remaining Collateral and all rights conveyed hereby in accordance with the next sentence. Pursuant to the satisfaction of the conditions set forth in Section 9.07(d)(iv) of the Credit Agreement or upon the complete payment of the Obligations under the Credit Agreement (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 compliance by the Grantors with all covenants and agreements hereof and the termination of the Aggregate Commitments, the US Administrative Agent, at the written request and expense of the Borrowers, will promptly release, reassign and transfer pursuant to Section 9.07(d) of the

Credit Agreement the Collateral to the Grantors and declare this Agreement to be of no further force or effect.

          (b) Partial Release. Notwithstanding anything contained herein to the contrary, the Grantors are authorized to release pursuant to Section 9.07(d) of the Credit Agreement any Collateral that is Transferred in compliance with Sections 10.08 and 10.14 of the Credit Agreement at which point the liens and security interests shall terminate with respect to such Collateral and this Agreement shall have no further force or effect with respect to such released Collateral; provided that so long as the lien in favor of the US Administrative Agent continues in the proceeds of such Transfer of such Collateral, or to the extent such Collateral is Transferred to any Borrower or any Subsidiary Guarantor, such lien continues in such Collateral.

          (c) Retention in Satisfaction. Except as may be expressly applicable pursuant to Section 9.620 of the UCC, no action taken or omission to act by the US Administrative Agent or the Secured Creditors hereunder, including, without limitation, any exercise of voting or consensual rights or any other action taken or inaction, shall be deemed to constitute a retention of the Collateral in satisfaction of the Obligations or otherwise to be in full satisfaction of the Obligations, and the Obligations shall remain in full force and effect, until the US Administrative Agent and the Secured Creditors shall have applied payments (including, without limitation, collections from Collateral) towards the Obligations in the full amount then outstanding or until such subsequent time as is provided in Section 8.12(a).

     Section 8.13 Acceptance. Each Grantor hereby expressly waives notice of acceptance of this Agreement, acceptance on the part of the US Administrative Agent and the Secured Creditors being conclusively presumed by their request for this Agreement and delivery of the same to the US Administrative Agent.
