This Guaranty Agreement covers the Guaranteed Indebtedness, whether presently outstanding or arising subsequent to the date hereof, including all amounts advanced by Agent or any of the Banks in stages or installments. The guaranty of Guarantor as set forth in this Section 2 is a continuing guaranty of payment and not a guaranty of collection. Guarantor acknowledges and agrees that Guarantor may be required to pay and perform the Guaranteed Indebtedness in full without assistance or support from Borrower or any other party.

different items of Guaranteed Indebtedness. Any such demand shall be made, given and received in accordance with the notice provisions in Section 21 hereof.

3. Performance. Guarantor hereby unconditionally and irrevocably guarantees to Agent for the benefit of the Banks the timely performance of the Guaranteed Performance Obligations, and not merely as a guaranty of collection. If any of the Guaranteed Performance Obligations of Borrower are not satisfied or complied with in any respect whatsoever, and without the necessity of any notice from Agent or any of the Banks to Guarantor, Guarantor agrees to indemnify and hold Agent and the Banks harmless from any and all loss, cost, liability or expense that Agent or any of the Banks may suffer by any reason of any such non-performance or non-compliance. The obligations and liability of Guarantor under this Section 3 shall not be limited or restricted by the existence of, or any terms of, the guaranty of payment under Section 2 of this Guaranty Agreement.

4. Primary Liability of Guarantor.

(a) This Guaranty Agreement is an absolute, irrevocable and unconditional guaranty of payment and performance. Guarantor is and shall be liable for the payment and performance of the Guaranteed Obligations, as set forth in this Guaranty Agreement, as a primary obligor.

(b) In the event of default in payment or performance of the Guaranteed Obligations, or any part thereof, when such Guaranteed Obligations become due, whether by its terms, by acceleration, or otherwise, Guarantor shall promptly pay the amount due thereon to Agent without notice or demand of any kind or nature, in lawful money of the United States of America or perform the obligations to be performed hereunder, and it shall not be necessary for Agent or any of the Banks in order to enforce such payment and performance by Guarantor first, or contemporaneously, to institute suit or exhaust remedies against Borrower or any other Person liable on the Guaranteed Obligations, or to enforce any rights, remedies, powers, privileges or benefits of Agent or the Banks against any collateral or any other security or collateral which shall ever have been given to secure the Guaranteed Obligations.

(c) Suit may be brought or demand may be made against Guarantor or any other guaranty covering all or any part of the Guaranteed Obligations, or against any one or more of them, separately or together, without impairing the rights of Agent against Guarantor. Any time that Agent is entitled to exercise its rights or remedies hereunder, Agent may in its sole discretion elect to demand payment and/or performance. If Agent elects to demand performance, then it shall at all times thereafter have the right to demand payment until all of the Guaranteed Obligations have been paid and performed in full (other than contingent indemnification obligations for which claims have not been asserted. If Agent elects to demand payment, then it shall at all times thereafter have the right to demand performance until all of the Guaranteed Obligations have been paid and performed in full (other than contingent indemnification obligations for which claims have not been asserted).

5. Other Guaranteed Obligations. If Guarantor becomes liable for any indebtedness owing by Borrower to Agent or any of the Banks, other than under this Guaranty Agreement, such liability shall not in any manner be impaired or affected hereby, and the rights

4

and remedies hereunder shall be cumulative of any and all other rights and remedies that Agent or any of the Banks may ever have against Guarantor. The exercise by Agent or any of the Banks of any right or remedy hereunder or under any other instrument, or at law or in equity, shall not preclude the concurrent or subsequent exercise of any other right or remedy by Agent or any of the Banks.

6. Waiver of Subrogation. Notwithstanding anything to the contrary contained herein, until the Guaranteed Obligations and any amounts payable under this Guaranty Agreement have been indefeasibly paid and performed in full (other than contingent indemnification obligations for which claims have not been asserted) and any commitments of Agent and the Banks with respect to the Guaranteed Obligations are terminated, Guarantor waives to the extent permitted by applicable law any right of subrogation, reimbursement, indemnification or contribution arising from the existence or performance of this Guaranty Agreement or any of the Loan Documents. This waiver is given to induce Agent and the Banks to make the Loan to Borrower.

7. Subordinated Debt. All indebtedness, liabilities, and obligations of Borrower or its Affiliates to Guarantor (the “Subordinated Debt”) now or hereafter existing, due or to become due to Guarantor, or held or to be held by Guarantor, whether created directly or acquired by assignment or otherwise, and whether evidenced by written instrument or not, shall be expressly subordinated to the Guaranteed Obligations. Until such time as the Guaranteed Obligations are paid and performed in full (other than contingent indemnification obligations for which claims have not been asserted) and all commitments to lend under the Loan Documents have terminated, Guarantor agrees not to receive or accept any payment from Borrower with respect to the Subordinated Debt at any time an Event of Default exists before or after giving effect thereto; and, in the event Guarantor receives any payment on the Subordinated Debt in violation of the foregoing, Guarantor will hold any such payment in trust for Agent and forthwith turn it over to Agent in the form received, to be applied to the Guaranteed Obligations, but without reducing or affecting in any manner the liability of the Guarantor under this Guaranty Agreement.

8. Obligations Not to be Diminished. Guarantor hereby agrees that its obligations under this Guaranty Agreement shall not be released, discharged, diminished, impaired, reduced, or affected for any reason or by the occurrence of any event, including, without limitation, one or more of the following events, whether or not with notice to or the consent of Guarantor: (a) the taking or accepting of collateral as security for any or all of the Guaranteed Obligations or the release, surrender, exchange, or subordination of any collateral now or hereafter securing any or all of the Guaranteed Obligations; (b) any partial release of the liability of Borrower or the full or partial release of any other guarantor or obligor from liability for any or all of the Guaranteed Obligations; (c) any disability of Borrower, or the dissolution, insolvency, or bankruptcy of Borrower, any other guarantor, or any other party at any time liable for the payment of any or all of the Guaranteed Obligations; (d) any renewal, extension, modification, waiver, amendment, or rearrangement of any or all of the Guaranteed Obligations or any instrument, document, or agreement evidencing, securing, or otherwise relating to any or all of the Guaranteed Obligations; (e) any adjustment, indulgence, forbearance, waiver, or compromise that may be granted or given by Agent to Borrower, Guarantor, or any other party ever liable for any or all of the Guaranteed Obligations; (f) any neglect, delay, omission, failure, or refusal of Agent to take or prosecute any action for the collection of any of the Guaranteed Obligations or to foreclose or take or prosecute any action in connection with any instrument, document, or agreement

5

evidencing, securing, or otherwise relating to any or all of the Guaranteed Obligations; (g) the unenforceability or invalidity of any or all of the Guaranteed Obligations or of any instrument, document, or agreement evidencing, securing, or otherwise relating to any or all of the Guaranteed Obligations; (h) any payment by Borrower or any other party to Agent is held to constitute a preference under applicable bankruptcy or insolvency law or if for any other reason Agent is required to refund any payment or pay the amount thereof to someone else; (i) the settlement or compromise of any of the Guaranteed Obligations; (j) the non-perfection of any security interest or Lien securing any or all of the Guaranteed Obligations; (k) any impairment of any collateral securing any or all of the Guaranteed Obligations; (l) the failure of Agent to sell any collateral securing any or all of the Guaranteed Obligations in a commercially reasonable manner or as otherwise required by law; (m) any change in the corporate, partnership, or limited liability company, as applicable, existence, structure, or ownership of Borrower; or (n) any other circumstance which might otherwise constitute a defense available to, or discharge of, Borrower or Guarantor.

9. Waivers. Guarantor waives for the benefit of Agent: (a) any right to revoke this Guaranty Agreement with respect to future indebtedness; (b) any right to require Agent to do any of the following before Guarantor is obligated to pay the Guaranteed Obligations or before Agent may proceed against Guarantor: (i) sue or exhaust remedies against Borrower or any other guarantors or obligors; (ii) sue on an accrued right of action in respect of any of the Guaranteed Obligations or bring any other action, exercise any other right, or exhaust all other remedies or (iii) enforce rights against Borrower’s assets or any collateral pledged by Borrower to secure the Guaranteed Obligations; (c) any right relating to the timing, manner, or conduct of Agent’s enforcement of rights against Borrower’s assets or any collateral pledged by Borrower to secure the Guaranteed Obligations; (d) if both Guarantor and Borrower or any other Person have pledged assets to secure the Guaranteed Obligations, any right to require Agent to proceed first against any such other collateral before proceeding against any collateral pledged by Guarantor; (e) except as expressly required hereby, promptness, diligence, notice of any default under the Guaranteed Obligations, notice of acceleration or intent to accelerate, demand for payment, notice of acceptance of this Guaranty Agreement, presentment, notice of protest, notice of dishonor, notice of the incurring by Borrower of additional indebtedness, notice of any suit or other action by Agent against Borrower or any other Person, any notice to any Person liable for the obligation which is the subject of the suit or action, and all other notices and demands with respect to the Guaranteed Obligations and this Guaranty Agreement; (f)(i) any principles or provisions of law, statutory, or otherwise, which are or might be in conflict with the terms hereof and any legal or equitable discharge of Guarantor’s obligations hereunder, (ii) the benefit of any statute of limitations affecting Guarantor’s liability hereunder or the enforcement hereof; and (iii) any requirement that Agent protect, secure, perfect or insure any security interest or Lien or any property subject thereto; and (g) each of the foregoing rights or defenses regardless whether they arise under (i) Section 43.001–005 of the Tex. Civ. Prac. & Rem.

10. Insolvency. Should Guarantor become insolvent, or fail to pay Guarantor’s debts generally as they become due, or voluntarily seek, consent to, or acquiesce in the benefit or

6

benefits of any Debtor Relief Law, or become a party to (or be made the subject of) any proceeding provided for by any Debtor Relief Law (other than as a creditor or claimant) that could suspend or otherwise adversely affect the rights and remedies of Agent granted hereunder, then, in any such event, the Guaranteed Obligations shall be, as between Guarantor and Agent and the Banks, a fully matured, due, and payable obligation of Guarantor to Agent and the Banks (without regard to whether Borrower is then in default under the Credit Agreement or whether the Obligations, or any part thereof is then due and owing by Borrower to Agent or any of the Banks), payable in full by Guarantor to Agent and the Banks upon demand, which shall be the estimated amount owing in respect of the contingent claim created hereunder.

11. Termination; Reinstatement. Guarantor’s obligations hereunder shall remain in full force and effect until all commitments to lend under the Loan Documents have terminated, and the Guaranteed Obligations have been paid and performed in full (other than contingent indemnification obligations for which claims have not been asserted). If at any time any payment of the principal of or interest or any other amount payable by Borrower under the Loan Documents is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy, or reorganization of Borrower or otherwise, then Guarantor’s obligations hereunder with respect to such payment shall be reinstated as though such payment had been due but not made at such time.

12. Stay of Acceleration. Should Borrower voluntarily seek, consent to, or acquiesce in the benefit or benefits of any Debtor Relief Law, or become a party to (or be made the subject of) any proceeding provided for by any Debtor Relief Law (other than as a creditor or claimant), all Guaranteed Obligations shall nonetheless be payable by Guarantor immediately if requested by Agent.

13. Representations and Warranties. Guarantor represents and warrants that: (a) it is duly organized and in good standing under the laws of the jurisdiction of its organization and has full capacity and right to make and perform this Guaranty Agreement, and all necessary authority has been obtained; (b) this Guaranty Agreement constitutes its legal, valid and binding obligation enforceable in accordance with its terms, except as limited by Debtor Relief Laws; (c) the making and performance of this Guaranty Agreement does not and will not violate the provisions of any applicable law, regulation or order, and does not and will not result in the breach of, or constitute a default or require any consent (that has not been obtained) under, any material agreement, instrument, or document to which Guarantor is a party or by which it or any of its property may be bound or affected; (d) all consents, approvals, licenses and authorizations of, and filings and registrations with, any governmental authority required under applicable law and regulations for the making and performance of this Guaranty Agreement have been obtained or made and are in full force and effect; (e) by virtue of its relationship with Borrower, the execution, delivery and performance of this Guaranty Agreement is for the direct benefit of Guarantor and it has received adequate consideration for this Guaranty Agreement; and (f) Guarantor has, independently and without reliance upon Agent or any of the Banks and based upon such documents and information as Guarantor has deemed appropriate, made its own analysis and decision to enter into this Guaranty Agreement, and Guarantor has adequate means to obtain from Borrower on a continuing basis information concerning the financial condition and assets of Borrower, and Guarantor is not relying upon Agent or any of the Banks to provide (and Agent and the Banks shall have no duty to provide) any such information to Guarantor either now or in the future.

15. No Fraudulent Transfer. It is the intention of Guarantor and Agent that the amount of the Guaranteed Obligations guaranteed by Guarantor by this Guaranty Agreement shall be in, but not in excess of, the maximum amount permitted by fraudulent conveyance, fraudulent transfer, or similar laws applicable to Guarantor (collectively, “Fraudulent Transfer Laws”). Accordingly, notwithstanding anything to the contrary contained in this Guaranty Agreement or any other agreement or instrument executed in connection with the payment of any of the Guaranteed Obligations, the amount of the Guaranteed Obligations guaranteed by Guarantor by this Guaranty Agreement shall be limited to that amount which after giving effect thereto would not (a) render Guarantor insolvent, (b) result in the fair saleable value of the assets of Guarantor being less than the amount required to pay its debts and other liabilities (including contingent liabilities) as they mature, or (c) leave Guarantor with unreasonably small capital to carry out its business as now conducted and as proposed to be conducted, including its capital needs, as such concepts described in clauses (a), (b) and (c) of this Section 15 are determined under applicable law, if the obligations of Guarantor hereunder would otherwise be set aside, terminated, annulled or avoided for such reason by a court of competent jurisdiction in a proceeding actually pending before such court. For purposes of this Guaranty Agreement, the term “applicable law” means as to Guarantor each statute, law, ordinance, regulation, order, judgment, injunction or decree of the United States or any state or commonwealth, any municipality, any foreign country, or any territory, possession or governmental authority applicable to Guarantor. Any analysis of the provisions of this Guaranty Agreement for purposes of Fraudulent Transfer Laws shall take into account the right of contribution against any Other Guarantor (as defined in Section 25) and, for purposes of such analysis, give effect to any discharge of intercompany debt as a result of any payment made under the Guaranty.

16. Successors and Assigns. This Guaranty Agreement is for the benefit of Agent and its successors and assigns, and, in the event of an assignment of the Guaranteed Obligations in accordance with the provisions of the Credit Agreement, or any part thereof, the rights and remedies hereunder, to the extent applicable to the indebtedness so assigned, may be transferred with such indebtedness. This Guaranty Agreement is binding on Guarantor and its successors and permitted assigns; provided that, Guarantor may not assign its obligations under this Guaranty Agreement without obtaining the prior written consent of Agent, and any assignment purported to be made without the prior written consent of Agent shall be null and void.

As further security for this Guaranty Agreement and the Guaranteed Obligations, Guarantor hereby grants Agent a security interest in all deposits (general or special, time or demand, provisional or final) other accounts of Guarantor, money, instruments, and other property of Guarantor now or hereafter on deposit with or held by Agent and all other sums at any time credited by or owing from Agent to Guarantor.
