In the case of each Guarantor, the representations and warranties set forth in Article VII of the Credit Agreement as they relate to such Guarantor (in its capacity as a Subsidiary of the Borrower) 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 the Borrower’s knowledge shall, for the purposes of this Section 5.01, be deemed to be a reference to such Guarantor’s knowledge.

Section 5.02 Benefit to the Guarantor. The Borrower is a member of an affiliated group of companies that includes each Guarantor, and the Borrower and the Guarantors are engaged in related businesses. Each Guarantor is a Subsidiary of the Borrower and its guaranty and surety obligations pursuant to this Agreement reasonably may be expected to benefit, directly or indirectly, it; 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 Borrower.

Section 5.03 Solvency.

Section 5.04 Title; No Other Liens. Except for the security interest granted to the Administrative Agent for the ratable benefit of the Secured Parties pursuant to this Agreement and Excepted Liens, such Grantor is the legal and beneficial owner of its respective items of the Collateral free and clear of any and all Liens. No financing statement or other public notice with respect to all or any part of the Collateral is on file or of record in any public office, except such as have been filed in favor of the Administrative Agent, for the ratable benefit of the Secured Parties, pursuant to this Agreement, the Security Instruments or as are filed to secure Liens permitted by Section 9.03 of the Credit Agreement.

Section 5.05 Perfected First Priority Liens. The security interests granted pursuant to this Agreement (a) upon completion of the filings and other actions specified on Schedule 3 (which, in the case of all filings and other documents referred to on said Schedule, have been delivered to the Administrative Agent in completed and duly executed form) will constitute valid perfected security interests in all of the Collateral in favor of the Administrative Agent, for the

9

ratable benefit of the Secured Parties, as collateral security for such Grantor’s obligations, enforceable in accordance with the terms hereof against all creditors of such Grantor and any Persons purporting to purchase any Collateral from such Grantor and (b) are prior to all other Liens on the Collateral in existence on the date hereof except for Excepted Liens which have priority over the Liens on the Collateral by operation of law.

Section 5.06 Legal Name, Organizational Status, Chief Executive Office. On the date hereof, the correct legal name of such Grantor, such Grantor’s jurisdiction of organization, organizational number, taxpayor identification number and the location of such Grantor’s chief executive office or sole place of business are specified on Schedule 4.

Section 5.07 Prior Names, Addresses, Locations of Tangible Assets. Schedule 5 correctly sets forth (a) all names and trade names that such Grantor has used in the last five years and (b) the chief executive office of such Grantor over the last five years (if different from that which is set forth in Section 5.06 above).

Section 5.08 Pledged Securities. The shares (or such other interests) of Pledged Securities pledged by such Grantor hereunder constitute all the issued and outstanding shares (or such other interests) of all classes of the capital stock or other Equity Interests of each Issuer owned by such Grantor.

16

agency upon such terms and conditions as the Administrative Agent may determine), all without liability except to account for property actually received by it, but the Administrative Agent shall have no duty to any Grantor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing.

(c) Each Grantor hereby authorizes and instructs each Issuer of any Pledged Securities pledged by such Grantor hereunder (and each Issuer party hereto hereby agrees) to (i) comply with any instruction received by it from the Administrative Agent in writing that (x) states that an Event of Default has occurred and is continuing and (y) is otherwise in accordance with the terms of this Agreement, without any other or further instructions from such Grantor, and each Grantor agrees that each Issuer shall be fully protected in so complying, and (ii) unless otherwise expressly permitted hereby, pay any dividends or other payments with respect to the Pledged Securities directly to the Administrative Agent.

(d) After the occurrence and during the continuation of an Event of Default, if the Issuer of any Pledged Securities is the subject of bankruptcy, insolvency, receivership, custodianship or other proceedings under the supervision of any Governmental Authority, then all rights of the Grantor in respect thereof to exercise the voting and other consensual rights which such Grantor would otherwise be entitled to exercise with respect to the Pledged Securities issued by such Issuer shall cease, and all such rights shall thereupon become vested in the Administrative Agent who shall thereupon have the sole right to exercise such voting and other consensual rights, but the Administrative Agent shall have no duty to exercise any such voting or other consensual rights and shall not be responsible for any failure to do so or delay in so doing.

Section 7.02 Collections on Accounts, Etc. The Administrative Agent hereby authorizes each Grantor to collect upon the Accounts, Instruments, Chattel Paper and Payment Intangibles subject to the Administrative Agent’s direction and control, and the Administrative Agent may curtail or terminate said authority at any time after the occurrence and during the continuance of an Event of Default.

17

such Grantor in trust for the Administrative Agent for the ratable benefit of the Secured Parties, 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 Administrative Agent (or by any Grantor in trust for the Administrative Agent for the ratable benefit of the Secured Parties) 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 Administrative Agent, or, if an Event of Default shall have occurred and be continuing, at any time at the Administrative Agent’s election, the Administrative Agent 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 Administrative Agent may elect, and any part of such funds which the Administrative Agent elects not so to apply and deems not required as collateral security for the Obligations shall be paid over from time to time by the Administrative Agent to each Grantor or to whomsoever may be lawfully entitled to receive the same.

Section 7.04 Texas UCC and Other Remedies.

(a) If an Event of Default shall occur and be continuing, the Administrative Agent, on behalf of the Secured Parties, may exercise in its discretion, in addition to all other rights, remedies, powers and privileges granted to them in this Agreement, the other Loan Documents, any Permitted Hedging Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights, remedies, powers and privileges of a secured party under the Texas UCC (whether the Texas UCC is in effect in the jurisdiction where such rights, remedies, powers or privileges are asserted) or any other applicable law or otherwise available at law or equity. Without limiting the generality of the foregoing, the Administrative Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon any Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of the Administrative Agent or any other Secured Party or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Administrative Agent or any other Secured Party shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in any Grantor, which right or equity is hereby waived and released. If an Event of Default shall occur and be continuing, each Grantor further agrees, at the Administrative Agent’s request, to assemble the Collateral and make it available to the Administrative Agent at places which the Administrative Agent shall reasonably select, whether at such Grantor’s premises or elsewhere. Any such sale or transfer by the Administrative Agent either to itself or to any other Person shall 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. Upon any such

18

sale or transfer, the Administrative Agent shall have the right to deliver, assign and transfer to the purchaser or transferee thereof the Collateral so sold or transferred. The Administrative Agent shall apply the net proceeds of any action taken by it pursuant to this Section 7.04, 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 Administrative Agent and the other Secured Parties hereunder, including, without limitation, reasonable attorneys’ fees and disbursements, to the payment in whole or in part of the Obligations, in accordance with Section 10.02 of the Credit Agreement, and only after such application and after the payment by the Administrative Agent of any other amount required by any provision of law, including, without limitation, Section 9.615 of the Texas UCC, need the 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 Administrative Agent or any other Secured Party 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 10 days before such sale or other disposition.

(b) In the event that the Administrative Agent elects not to sell the Collateral, the 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. The 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 7.05 Private Sales of Pledged Securities. Each Grantor recognizes that the Administrative Agent may be unable to effect a public sale of any or all the Pledged Securities, by reason of certain prohibitions contained in the Securities Act and applicable state securities laws or otherwise, and may be compelled to resort to one or more private sales thereof to a restricted group of purchasers which will be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. Each Grantor acknowledges and agrees that any such private sale may result in prices and other terms less favorable than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner. The Administrative Agent shall be under no obligation to delay a sale of any of the Pledged Securities for the period of time necessary to permit the Issuer thereof to register such securities for public sale under the Securities Act, or under applicable state securities laws, even if such Issuer would agree to do so. Each Grantor agrees to use its best efforts to do or cause to be done all such other acts as may reasonably be necessary to make such sale or sales of all or any portion of the Pledged Securities pursuant to this Section 7.05 valid and binding and in compliance with any and all other applicable Governmental Requirements. Each Grantor further agrees that a breach of any of the covenants contained in this Section 7.05 will cause irreparable injury to the Administrative Agent and the other Secured Parties, that the Administrative Agent and the other Secured Parties have no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section 7.05 shall be specifically enforceable against such Grantor, and such Grantor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants.

19

Section 7.06 Waiver; Deficiency. Each Grantor waives and agrees not to assert any rights or privileges which it may acquire under the Texas UCC or any other applicable law. Each Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay its Obligations and the fees and disbursements of any attorneys employed by the Administrative Agent or any other Secured Party to collect such deficiency.

Section 7.07 Non-Judicial Enforcement. The 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 Administrative Agent to enforce its rights by judicial process.

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; (D) sign and indorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against debtors, assignments, verifications, notices and other documents in connection with any of the Collateral; (E) receive, change the address for delivery, open and dispose of mail addressed to any Grantor, and to execute, assign and indorse negotiable and other instruments for the payment of money, documents of title or other evidences of payment, shipment or storage for any form of Collateral on behalf of and in the name of any Grantor; (F) 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; (G) defend any suit, action or proceeding brought against such Grantor with respect to any Collateral; (H) settle, compromise or adjust any such suit, action or proceeding and, in connection therewith, give such discharges or releases as the Administrative Agent may deem appropriate; and (I) generally, sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Administrative Agent were the absolute owner thereof for all purposes, and do, at the Administrative Agent’s option and such Grantor’s expense, at any time, or from time to time, all acts and things which the Administrative Agent deems necessary to protect, preserve or realize upon the Collateral and the Administrative Agent’s and the other Secured Parties’ security interests therein and to effect the intent of this Agreement, all as fully and effectively as such Grantor might do.

Anything in this Section 8.01(a) to the contrary notwithstanding, the Administrative Agent agrees that it will not exercise any rights under the power of attorney provided for in this Section 8.01(a) unless an Event of Default shall have occurred and be continuing.

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

(c) The expenses of the Administrative Agent incurred in connection with actions undertaken as provided in this Section 8.01, together with interest thereon at the Post-Default Rate from the date of payment by the Administrative Agent to the date reimbursed by the relevant Grantor, shall be payable by such Grantor to the Administrative Agent on demand.

(d) Each Grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue and in compliance hereof. All powers, authorizations and agencies contained in this Agreement are coupled with an interest and are irrevocable until this Agreement is terminated and the security interests created hereby are released.

Section 8.02 Duty of Administrative Agent. The Administrative Agent’s sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9.207 of the Texas UCC or otherwise, shall be to deal with it in the same manner as the Administrative Agent deals with similar property for its own account 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

21

secured parties accord comparable collateral. Neither the Administrative Agent, any other Secured Party nor any of their respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The powers conferred on the Administrative Agent and the other Secured Parties hereunder are solely to protect the Administrative Agent’s and the other Secured Parties’ interests in the Collateral and shall not impose any duty upon the Administrative Agent or any other Secured Party to exercise any such powers. The Administrative Agent and the other Secured Parties 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 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 Administrative Agent or any other Secured Party to proceed against any Grantor or other Person, exhaust any Collateral or enforce any other remedy which the Administrative Agent or any other Secured Party now has or may hereafter have against each Grantor, any Grantor or other Person.

Section 8.03 Execution of Financing Statements. Pursuant to the Texas UCC and any other applicable law, each Grantor authorizes the Administrative Agent, its counsel or its representative, at any time and from time to time, to file or record financing statements, continuation statements, amendments thereto and other filing or recording documents or instruments with respect to the Collateral without the signature of such Grantor in such form and in such offices as the Administrative Agent reasonably determines appropriate to perfect the security interests of the Administrative Agent under this Agreement. Additionally, each Grantor authorizes the Administrative Agent, its counsel or its representative, at any time and from time to time, to file or record such financing statements that describe the collateral covered thereby as “all assets of the Grantor”, “all personal property of the Grantor” or words of similar effect. 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 8.04 Authority of Administrative Agent. Each Grantor acknowledges that the rights and responsibilities of the Administrative Agent under this Agreement with respect to any action taken by the Administrative Agent or the exercise or non-exercise by the Administrative Agent of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Agreement shall, as between the Administrative Agent and the other Secured Parties, be governed by the Credit Agreement and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Administrative Agent and the Grantors, the Administrative Agent shall be conclusively presumed to be acting as agent for the Secured Parties 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 IX

Subordination of Indebtedness

Section 9.01 Subordination of All Guarantor Claims. As used herein, the term “Guarantor Claims” shall mean all debts and obligations of the Borrower or any other Grantor to any 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. 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 Guarantor Claims.

Section 9.02 Claims in Bankruptcy. In the event of receivership, bankruptcy, reorganization, arrangement, debtor’s relief or other insolvency proceedings involving any Grantor, the Administrative Agent on behalf of the Secured Parties 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 Grantor hereby assigns such dividends and payments to the Administrative Agent for the benefit of the Secured Parties for application against the Obligations as provided under Section 10.02 of the Credit Agreement. Should any Agent or Secured Party receive, for application upon the Obligations, any such dividend or payment which is otherwise payable to any Grantor, and which, as between such Grantor, shall constitute a credit upon the Guarantor Claims, then upon payment in full of the Obligations, the intended recipient shall become subrogated to the rights of the Administrative Agent and the other Secured Parties to the extent that such payments to the Administrative Agent and the other Secured Parties on the Guarantor 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 Administrative Agent and the other Secured Parties had not received dividends or payments upon the Guarantor Claims.

Section 9.03 Payments Held in Trust. In the event that notwithstanding Section 9.01 and Section 9.02, 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 Administrative Agent and the other Secured Parties 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 Administrative Agent, for the benefit of the Secured Parties; and each Grantor covenants promptly to pay the same to the Administrative Agent.

Section 9.04 Liens Subordinate. Each Grantor agrees that, until the Obligations are paid in full and the Aggregate Commitments terminated, any Liens securing payment of the Guarantor Claims shall be and remain inferior and subordinate to any Liens securing payment of

23

the Obligations, regardless of whether such encumbrances in favor of such Grantor, the Administrative Agent or any other Secured Party presently exist or are hereafter created or attach. Without the prior written consent of the 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 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.

Section 9.05 Notation of Records. Upon the request of the Administrative Agent, all promissory notes and all accounts receivable ledgers or other evidence of the Guarantor 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 X

Miscellaneous

Section 10.01 Waiver. No failure on the part of the Administrative Agent or any other Secured Party to exercise and no delay in exercising, and no course of dealing with respect to, any right, remedy, power or privilege under any of the Loan Documents shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege under any of the Loan Documents preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges provided herein are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law. The exercise by the Administrative Agent of any one or more of the rights, powers and remedies herein shall not be construed as a waiver of any other rights, powers and remedies, including, without limitation, any rights of set-off.

Section 10.02 Notices. All notices and other communications provided for herein shall be given in the manner and subject to the terms of Section 12.01 of the Credit Agreement; provided that any such notice, request or demand to or upon any Guarantor shall be addressed to such Guarantor at its notice address set forth on Schedule 1.

Section 10.03 Payment of Expenses, Indemnities, Etc.

(a) Each Grantor agrees to pay or promptly reimburse the Administrative Agent and each other Secured Party for all advances, charges, costs and expenses (including, without limitation, all costs and expenses of holding, preparing for sale and selling, collecting or otherwise realizing upon the Collateral and all attorneys’ fees, legal expenses and court costs) incurred by any Secured Party in connection with the exercise of its respective rights and remedies hereunder, including, without limitation, any advances, charges, costs and expenses that may be incurred in any effort to enforce any of the provisions of this Agreement or any obligation of any Grantor in respect of the Collateral or in connection with (i) the preservation of the Lien of, or the rights of the Administrative Agent or any other Secured Party under this Agreement, (ii) any actual or attempted sale, lease, disposition, exchange, collection, compromise, settlement or other realization in respect of, or care of, the Collateral, including all

24

such costs and expenses incurred in any bankruptcy, reorganization, workout or other similar proceeding, or (iii) collecting against such Grantor under the guarantee contained in Article II or otherwise enforcing or preserving any rights under this Agreement and the other Loan Documents to which such Grantor is a party.

(b) Each Grantor agrees to pay, and to save the Administrative Agent and the other Secured Parties harmless from, any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever (including, without limitation, court costs and attorneys’ fees, any and all liabilities with respect to, or resulting from any delay in paying, any and all stamp, excise, sales or other taxes which may be payable or determined to be payable with respect to any of the Collateral or in connection with any of the transactions contemplated by this Agreement) incurred because of, incident to, or with respect to, the Collateral (including, without limitation, any exercise of rights or remedies in connection therewith) or the execution, delivery, enforcement, performance and administration of this Agreement, to the extent the Borrower would be required to do so pursuant to Section 12.03 of the Credit Agreement. All amounts for which any Grantor is liable pursuant to this Section 10.03 shall be due and payable by such Grantor to the Secured Parties upon demand.

Section 10.04 Amendments in Writing. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except in accordance with Section 12.02 of the Credit Agreement.

Section 10.05 Successors and Assigns. This Agreement shall be binding upon the successors and assigns of each Grantor and shall inure to the benefit of the Administrative Agent and the other Secured Parties and their successors and assigns; provided that except as set forth in Section 8.14 or Section 9.13 of the Credit Agreement, no Grantor may assign, transfer or delegate any of its rights or obligations under this Agreement without the prior written consent of the Administrative Agent and the Lenders.

Section 10.06 Invalidity. In the event that any one or more of the provisions contained in this Agreement or in any of the Loan Documents to which a Grantor is a party shall, for any reason, be held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement or such other Loan Document.

Section 10.07 Counterparts. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one and the same instrument and any of the parties hereto may execute this Agreement by signing any such counterpart.

Section 10.08 Survival. The obligations of the parties under Section 10.03 shall survive the repayment of the Loans and the termination of the Letters of Credit, Permitted Hedging Agreements, Credit Agreement and Aggregate Commitments. 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

25

had not been received and the Administrative Agent’s and the other Secured Parties’ Liens, security interests, rights, powers and remedies under this Agreement and each Security Instrument shall continue in full force and effect. In such event, each Security Instrument shall be automatically reinstated and each Grantor shall take such action as may be reasonably requested by the Administrative Agent and the other Secured Parties to effect such reinstatement.

Section 10.09 Captions. Captions and section headings appearing herein are included solely for convenience of reference and are not intended to affect the interpretation of any provision of this Agreement.

Section 10.10 No Oral Agreements. The Loan Documents (other than the Letters of Credit) embody the entire agreement and understanding between the parties and supersede all other agreements and understandings between such parties relating to the subject matter hereof and thereof. The Loan Documents represent the 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.

Section 10.11 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 Documents to which a Grantor is a party shall be brought in the courts of the State of Texas or of the United States of America for the Southern District of Texas, and each of the Lenders, the Administrative Agent and the Grantors 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. Each of the Lenders, the Administrative Agent and the Grantors hereby irrevocably waives any objection, including, without limitation, any objection to the laying of venue or based on the grounds of forum non conveniens, which it may now or hereafter have to the bringing of any such action or proceeding in such respective jurisdictions. This submission to jurisdiction is non-exclusive and does not preclude the Administrative Agent or any Lender from obtaining jurisdiction over such Grantor in any court otherwise having jurisdiction.

(c) Each of the Lenders, the Administrative Agent and the Grantors 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 Person at the address specified on its signature page of this Agreement or the Credit Agreement, as applicable, such service to become effective thirty (30) days after such mailing. Nothing herein shall affect the right of the Administrative Agent or any Lender or any holder of a Note or Grantor to serve process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against such Grantor in any other jurisdiction.

(d) Each Grantor and each Lender hereby (i) irrevocably and unconditionally waive, to the fullest extent permitted by law, trial by jury in any legal action or proceeding relating to this Agreement or any other Loan Document and for any counterclaim therein; (ii) irrevocably waive, to the maximum extent not prohibited by law, any right it may have to claim or recover in

26

any such litigation any special, exemplary, punitive or consequential damages, or damages other than, or in addition to, actual damages; (iii) certify that no party hereto nor any representative or agent of counsel for any party hereto has represented, expressly or otherwise, or implied that such party would not, in the event of litigation, seek to enforce the foregoing waivers, and (iv) acknowledge that it has been induced to enter into this Agreement, the Loan Documents and the transactions contemplated hereby and thereby by, among other things, the mutual waivers and certifications contained in this Section 10.11.

Section 10.12 Acknowledgments. Each Grantor hereby acknowledges that:

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

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

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

(d) Each of the parties hereto specifically agrees that it has a duty to read this Agreement and the Security Instruments and agrees that it is charged with notice and knowledge of the terms of this Agreement and the Security Instruments; that it has in fact read this Agreement and is fully informed and has full notice and knowledge of the terms, conditions and effects of this Agreement; that it has been represented by independent legal counsel of its choice throughout the negotiations preceding its execution of this Agreement and the Security Instruments; and has received the advice of its attorney in entering into this Agreement and the Security Instruments; and that it recognizes that certain of the terms of this Agreement and the Security Instruments result in one party assuming the liability inherent in some aspects of the transaction and relieving the other party of its responsibility for such liability. 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.”

(e) Each Grantor warrants and agrees that each of the waivers and consents set forth in this Agreement are made voluntarily and unconditionally after consultation with outside legal counsel and with full knowledge of their significance and consequences, with the understanding that events giving rise to any defense or right waived may diminish, destroy or otherwise adversely affect rights which such Grantor otherwise may have against the Borrower, any other Grantor, the Secured Parties or any other Person or against any collateral. If, notwithstanding the intent of the parties that the terms of this Agreement shall control in any and all circumstances, any such waivers or consents are determined to be unenforceable under applicable law, such waivers and consents shall be effective to the maximum extent permitted by law.

27

Section 10.13 Additional Grantors. Each Subsidiary of the Borrower that is required to become a party to this Agreement pursuant to Section 8.11 of the Credit Agreement and is not a signatory hereto shall become a Grantor for all purposes of this Agreement upon execution and delivery by such Subsidiary of an Assumption Agreement in the form of Annex I hereto.

Section 10.14 Set-Off. Each Grantor agrees that, in addition to (and without limitation of) any right of set-off, bankers’ lien or counterclaim a Secured Party may otherwise have, each Secured Party shall have the right and be entitled (after consultation with the Administrative Agent), at its option, to offset (i) balances held by it or by any of its Affiliates for account of any Grantor or any Subsidiary at any of its offices, in Dollars or in any other currency, and (ii) amounts due and payable to such Lender (or any Affiliate of such Lender) under any Permitted Hedging Agreement, against any principal of or interest on any of such Secured Party’s Loans, or any other amount due and payable to such Secured Party hereunder, which is not paid when due (regardless of whether such balances are then due to such Person), in which case it shall promptly notify the Borrower and the Administrative Agent thereof, provided that such Secured Party’s failure to give such notice shall not affect the validity thereof.

Section 10.15 Releases.

(a) Release Upon Payment in Full. 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 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. Upon the complete payment of the Obligations, the termination of the Letters of Credit, Permitted Hedging Agreements secured hereby, Credit Agreement and the Aggregate Commitments and the compliance by the Grantors with all covenants and agreements hereof, the Administrative Agent, at the written request and expense of the Borrower, will promptly release, reassign and transfer the Collateral to the Grantors and declare this Agreement to be of no further force or effect.

(b) Further Assurances. If any of the Collateral shall be sold, transferred or otherwise disposed of by any Grantor in a transaction permitted by the Credit Agreement, then the Administrative Agent, at the request and sole expense of such Grantor, shall promptly execute and deliver to such Grantor all releases or other documents reasonably necessary or desirable for the release of the Liens created hereby on such Collateral and the capital stock of such Grantor. At the request and sole expense of the Borrower, a Grantor shall be released from its obligations hereunder in the event that all the capital stock of such Grantor shall be sold, transferred or otherwise disposed of in a transaction permitted by the Credit Agreement; provided that the Borrower shall have delivered to the Administrative Agent, at least ten Business Days prior to the date of the proposed release, a written request for release identifying the relevant Grantor and the terms of the sale or other disposition in reasonable detail, including the price thereof and any expenses in connection therewith, together with a certification by the Borrower stating that such transaction is in compliance with the Credit Agreement and the other Loan Documents.

28

(c) Retention in Satisfaction. Except as may be expressly applicable pursuant to Section 9.620 of the Texas UCC, no action taken or omission to act by the Administrative Agent or the other Secured Parties 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 Administrative Agent and the other Secured Parties 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 10.15(a).

Section 10.16 Reinstatement. The obligations of each Grantor under this Agreement (including, without limitation, with respect to the guarantee contained in Article II and the provision of collateral herein) shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by the Administrative Agent or any other Secured Party upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Borrower or any Grantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Borrower or any Grantor or any substantial part of its property, or otherwise, all as though such payments had not been made.

Section 10.17 Acceptance. Each Grantor hereby expressly waives notice of acceptance of this Agreement, acceptance on the part of the Administrative Agent and the other Secured Parties being conclusively presumed by their request for this Agreement and delivery of the same to the Administrative Agent.
