Specifically, however, if at any time any Governmental Authority, applicable law, regulation or international agreement requires Borrower to make any withholding or deduction from any such payment or other sum payable hereunder to Lender, Borrower hereby covenants and agrees that the amount due from Borrower with respect to such payment or other sum payable hereunder will be increased to the extent necessary to ensure that, after the making of such required withholding or deduction, Lender receives a net sum equal to the sum which it would have received had no withholding or deduction been required, and Borrower shall pay the full amount withheld or deducted to the relevant Governmental Authority prior to the earlier of (i) delinquency or (ii) five (5) Business Days after Borrower’s receipt of written notice thereof.

(b)Borrower shall timely pay to the relevant Governmental Authority in accordance with applicable law, or at the option of Lender timely reimburse it for the payment of, any other Taxes.

4

Authority. A certificate as to the amount of such payment or liability delivered to Borrower by Lender shall be conclusive absent manifest error.

(d)As soon as practicable after any payment of withholding or deduction by Borrower to a Governmental Authority pursuant to this Section 2.8, Borrower shall deliver to Lender the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to Lender.

(a)upon notice to Borrower, declare all Obligations immediately due and payable (but if an Event of Default described in Section 8.5 occurs all Obligations shall be automatically and immediately due and payable without any action by Lender);

(b)make any payments and do any acts it considers necessary or reasonable to protect the Collateral and/or its security interest in the Collateral. The Loan Parties shall assemble the Collateral if Lender requests and make it available at a place and time to be designated by Lender that is reasonably convenient to both parties. Lender may occupy any premises owned or, to the extent lawful and permitted, leased by any of the Loan Parties where the Collateral or any part thereof is assembled or located for a reasonable period in order to effectuate its rights and remedies hereunder or under applicable law, without obligation to pay rent or otherwise to such

12

Loan Party or any other Person in respect of such occupation; provided that Lender shall provide the applicable Loan Party with notice thereof prior to or promptly after such occupancy;

(c)exercise all rights and remedies available to Lender under the Loan Documents or at law or equity, including all remedies provided under the Code (including disposal of the Collateral pursuant to the terms thereof);

(d)take any actions pursuant to Section 9.8; and

(e)subject to the mandatory requirements of applicable law and the notice requirements described below, sell or otherwise dispose of all or any part of the Collateral securing the Obligations at a public or private sale or at any broker’s board or on any securities exchange, for cash, upon credit or for future delivery as Lender shall deem appropriate. Lender shall be authorized at any such sale of securities (if it deems it advisable to do so) to restrict the prospective bidders or purchasers to Persons who will represent and agree that they are purchasing the Collateral for their own account for investment and not with a view to the distribution or sale thereof, and upon consummation of any such sale Lender shall have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral so sold. Each such purchaser at any sale of Collateral shall hold the property sold absolutely, free from any claim or right on the part of any Loan Party, and each Loan Party hereby waives (to the extent permitted by applicable law) all rights of redemption, stay and appraisal which such Loan Party now has or may at any time in the future have under any applicable law now existing or hereafter enacted.

Lender shall give the applicable Loan Party(ies) ten (10) calendar days’ written notice (which each Loan Party agrees is commercially reasonable notice within the meaning of Section 9‑611 of the Code or its equivalent in other jurisdictions) of Lender’s intention to make any sale of Collateral. Such notice, in the case of a public sale, shall state the time and place for such sale and, in the case of a sale at a broker’s board or on a securities exchange, shall state the board or exchange at which such sale is to be made and the day on which the Collateral, or portion thereof, will first be offered for sale at such board or exchange. Any such public sale shall be held at such time or times within ordinary business hours and at such place or places as Lender may fix and state in the notice (if any) of such sale. At any such sale, the Collateral, or portion thereof, to be sold may be sold in one lot as an entirety or in separate parcels, as the Agent may (in its sole and absolute discretion) determine. Lender shall not be obligated to make any sale of any Collateral if it shall determine not to do so, regardless of the fact that notice of sale of such Collateral shall have been given. Lender may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may, without further notice, be made at the time and place to which the same was so adjourned. In case any sale of all or any part of the Collateral is made on credit or for future delivery, the Collateral so sold may be retained by Lender until the sale price is paid by the purchaser or purchasers thereof, but Lender shall not incur any liability in case any such purchaser or purchasers shall fail to take up and pay for the Collateral so sold and, in case of any such failure, such Collateral may be sold again upon like notice. At any public (or, to the extent permitted by applicable law, private) sale made pursuant to this Agreement, Lender may bid for or purchase, free (to the extent permitted by applicable law) from any right of redemption, stay, valuation or appraisal on the part of any Loan Party (all said rights being also hereby waived and released to the extent permitted by applicable law), the

13

Collateral or any part thereof offered for sale and may make payment on account thereof by using any claim then due and payable to Lender from any Loan Party as a credit against the purchase price, and Lender may, upon compliance with the terms of sale, hold, retain and dispose of such property without further accountability to any Grantor therefor. Lender may sell any Collateral in accordance with the provisions of this Agreement and the other Loan Documents and applicable law without giving any warranties as to such Collateral. Lender may specifically disclaim or modify any warranties of title or the like. Lender shall have no obligation to marshal any of the Collateral. For purposes hereof, a written agreement to purchase the Collateral or any portion thereof shall be treated as a sale thereof, Lender shall be free to carry out such sale pursuant to such agreement and no Loan Party shall be entitled to the return of the Collateral or any portion thereof subject thereto, notwithstanding the fact that after Lender shall have entered into such an agreement all Events of Default shall have been remedied and the Obligations paid in full. As an alternative to exercising the power of sale herein conferred upon it, Lender may proceed by a suit or suits at law or in equity to foreclose this Agreement and to sell the Collateral or any portion thereof pursuant to a judgment or decree of a court or courts having competent jurisdiction or pursuant to a proceeding by a court-appointed receiver. Any sale pursuant to the provisions of this Section shall be deemed to conform to the commercially reasonable standards as provided in Section 9-610(b) of the Code or its equivalent in other jurisdictions.

9.2 Power of Attorney. Each Loan Party hereby irrevocably appoints Lender as its lawful attorney-in-fact, after the occurrence and during the continuance of an Event of Default upon prior written notice to Borrower (unless an Event of Default under Section 8.5 has occurred and is continuing, in which case no such notice shall be required), to: (i) make, settle, and adjust all claims in respect of the Collateral under any Guarantor’s insurance policies; (ii) pay, contest or settle any Lien, charge, encumbrance, security interest, or other claim in or to the Collateral, or any judgment based thereon, or otherwise take any action to terminate or discharge the same; and (iii) transfer the Collateral into the name of Lender or a third party as the Code permits. Each Guarantor hereby appoints Lender as its lawful attorney-in-fact to sign such Guarantor’s name on any documents necessary to perfect or continue the perfection of Lender’s security interest in the Collateral after an Event of Default has occurred and is continuing until all Obligations (other than contingent indemnification obligations for which no claim has been made) have been satisfied in full and the Loan Documents have been terminated. Lender’s foregoing appointment as each Loan Party’s attorney in fact, and all of Lender’s rights and powers, coupled with an interest, are irrevocable until all Obligations (other than contingent indemnification obligations for which no claim has been made) have been fully repaid and performed and the Loan Documents have been terminated.

9.3 Protective Payments. After an Event of Default shall have occurred and be continuing, if any Guarantor fails to obtain the insurance called for by Section 6.5 or fails to pay any premium thereon or fails to pay any other amount which such Guarantor is obligated to pay under this Agreement or any other Loan Document or which may be required to preserve the Collateral, Lender may obtain such insurance or make such payment, and all amounts so paid by Lender are Lender Expenses and immediately due and payable, bearing interest at the Default Rate, and secured by the Collateral. Lender shall provide Borrower with notice of Lender

14

obtaining such insurance at the time it is obtained. No payments by Lender are deemed an agreement to make similar payments in the future or Lender’s waiver of any Event of Default.

9.4 Application of Payments and Proceeds. After an Event of Default shall have occurred and be continuing, Lender shall have the right to apply any of any Loan Party’s funds in its possession to the Obligations in any order. If Lender, directly or indirectly, enters into a deferred payment or other credit transaction with any purchaser at any sale of Collateral, Lender shall have the option, exercisable at any time, of either reducing the Obligations by the principal amount of the purchase price or deferring the reduction of the Obligations until the actual receipt by Lender of cash therefor.

9.5 Lender’s Liability for Collateral. So long as Lender treats the Collateral in the possession or under the control of Lender in substantially the same manner to that which it accords its own property, Lender shall not be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the value of the Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other Person. The Loan Parties bears all risk of loss, damage or destruction of the Collateral.

9.6 No Waiver; Remedies Cumulative. Lender’s failure, at any time or times, to require strict performance by the Loan Parties of any provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right of Lender thereafter to demand strict performance and compliance herewith or therewith. No waiver hereunder shall be effective unless signed by the party granting the waiver and then is only effective for the specific instance and purpose for which it is given. Lender’s rights and remedies under this Agreement and the other Loan Documents are cumulative. Lender has all rights and remedies provided under the Code, by law, or in equity. Lender’s exercise of one right or remedy is not an election and shall not preclude Lender from exercising any other remedy under this Agreement or other remedy available at law or in equity, and Lender’s waiver of any Event of Default is not a continuing waiver. Lender’s delay in exercising any remedy is not a waiver, election, or acquiescence.

9.7 Waivers. Except for any notices expressly required by Lender under the Loan Documents, each Loan Party waives, to the extent permitted by applicable law, (i) demand, notice of default or dishonor, notice of payment and nonpayment, notice of any default, notice of intent to accelerate, notice of acceleration, notice of nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by Lender on which such Loan Party is liable; (ii) notice before taking possession or control of any Collateral; (iii) any bond or security that might be required by a court before allowing Lender to exercise any rights or remedies under this Agreement or the other Loan Documents; (iv) any claim against Lender on any theory of liability, for special, indirect, consequential, exemplary, or punitive damages (as opposed to direct or actual damages) in any way relating to Obligations, this Agreement or the other Loan Documents, or transactions relating hereto or thereto or any act to collect on the Obligations, enforce any Loan Document or realize upon any Collateral,; (v) notice of acceptance hereof; (vi) all rights to interpose any claims, deductions, setoffs, or counterclaims of any nature (other than compulsory counterclaims) in any action or proceeding with respect to this Agreement, the other Loan Documents, the Obligations, the Collateral, or any matter arising therefrom or relating hereto or thereto; and (vii) any claim under any law or equitable principle requiring Lender to marshal any assets in favor of any Loan Party or against any Obligations or otherwise attempt to realize upon

15

any Collateral, or any appraisement, evaluation, stay, extension, homestead, redemption, or exemption laws now or hereafter in force to prevent or hinder the enforcement of this Agreement. Each Loan Party acknowledges that the foregoing waivers are a material inducement Lender’s entering into this Agreement and that Lender is relying upon the foregoing in their dealings with such Loan Party.

10.NOTICES

11.CHOICE OF LAW, VENUE, JURY TRIAL WAIVER AND JUDICIAL REFERENCE

Except as otherwise expressly provided in any of the Loan Documents, Texas law governs the Loan Documents without regard to principles of conflicts of law. Each Loan Party submits to the exclusive jurisdiction of any U.S. federal or Texas State court sitting in Dallas, Texas; provided, however, that nothing in this Agreement shall be deemed to operate to preclude

16

Lender from bringing suit or taking other legal action in any other jurisdiction. Each Loan Party expressly submits and consents in advance to such jurisdiction in any action or suit commenced in any such court, and each Loan Party hereby waives any objection that it may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of such legal or equitable relief as is deemed appropriate by such court. Each Loan Party hereby waives personal service of the summons, complaints, and other process issued in such action or suit and agrees that service of such summons, complaints, and other process may be made by registered or certified mail addressed to such Loan Party at the address set forth in, or subsequently provided by such Loan Party in accordance with, Section 10 of this Agreement and that service so made shall be deemed completed upon the earlier to occur of such Loan Party’s actual receipt thereof or three (3) days after deposit in the U.S. mails, proper postage prepaid.

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, EACH LOAN PARTY AND LENDER EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR EACH PARTY TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

This Section 11 shall survive the termination of this Agreement.

12.GENERAL PROVISIONS

12.1Termination Prior to Maturity Date; Survival. All covenants, representations and warranties made in this Agreement shall continue in full force until this Agreement has terminated pursuant to its terms and all Obligations (other than contingent indemnification obligations for which no claim has been made) have been satisfied. So long as Borrower has satisfied the Obligations in full in accordance with Section 2.7(c) (other than contingent indemnification obligations for which no claim has been made, and any other obligations which, by their terms, are to survive the termination of this Agreement), this Agreement may be terminated prior to the Maturity Date by Borrower, effective three (3) Business Days after written notice of termination is given to Lender. Those obligations that are expressly specified in this Agreement as surviving this Agreement’s termination shall continue to survive notwithstanding this Agreement’s termination.

12.2Successors and Assigns. This Agreement binds and is for the benefit of the successors and permitted assigns of each party. No Loan Party may assign this Agreement or any rights or obligations under it without Lender’s prior written consent (which may be granted or withheld in Lender’s sole discretion). After the occurrence of an Event of Default, Lender has the right, without the consent of or notice to Borrower, to sell, transfer, assign, negotiate, or grant participation in all or any part of, or any interest in, Lender’s obligations, rights, and benefits under this Agreement and the other Loan Documents.

12.3Indemnification. Each Loan Party agrees to indemnify, defend and hold Lender and its directors, officers, employees, agents, attorneys, advisors or any Affiliate of Lender (each, an “Indemnified Person”) harmless against: (i) all obligations, demands, claims, and liabilities

17

(collectively, “Claims”) claimed or asserted by any other party in connection with the transactions contemplated by the Loan Documents; and (ii) all losses or expenses (including Lender Expenses) in any way suffered, incurred, or paid by such Indemnified Person as a result of, following from, consequential to, or arising from transactions between Lender and any Loan Party (including reasonable attorneys’ fees and expenses actually incurred); provided that such indemnity shall not, as to any Indemnified Person, be available to the extent that such Claims are (A) determined by a final and non-appealable judgment of a court of competent jurisdiction to have resulted from the bad faith, gross negligence or willful misconduct of such Indemnified Person, (B) in respect of any settlement entered into by any Indemnified Person without the prior written consent of Borrower (which consent will not be unreasonably withheld, delayed or conditioned), (C) in respect of (1) a material breach of the Loan Documents by such Indemnified Person or one of its Affiliates or (2) any dispute solely among Indemnified Persons and other than any claims arising out of any act or omission of any Loan Party or any of its Subsidiaries or (3) attributable to Taxes (other than any Taxes that represent losses, claims, damages, liabilities or related expenses arising from any non-Tax claim), which shall be governed solely by Section 2.8.

12.4Time of Essence. Time is of the essence for the performance of all obligations in this Agreement.

12.5Severability of Provisions. Each provision of this Agreement is severable from every other provision in determining the enforceability of any provision.

12.6Correction of Loan Documents. Lender may correct patent errors and fill in any blanks in the Loan Documents consistent with the agreement of the parties.

12.7Amendments in Writing; Waiver; Integration. No purported amendment or modification of any Loan Document, or waiver, discharge or termination of any obligation under any Loan Document, shall be enforceable or admissible unless, and only to the extent, expressly set forth in a writing signed by the party against which enforcement or admission is sought. Without limiting the generality of the foregoing, no oral promise or statement, nor any action, inaction, delay, failure to require performance or course of conduct shall operate as, or evidence, an amendment, supplement or waiver or have any other effect on any Loan Document. Any waiver granted shall be limited to the specific circumstance expressly described in it and shall not apply to any subsequent or other circumstance, whether similar or dissimilar, or give rise to, or evidence, any obligation or commitment to grant any further waiver. The Loan Documents represent the entire agreement about this subject matter and supersede prior negotiations or agreements. All prior agreements, understandings, representations, warranties, and negotiations between the parties about the subject matter of the Loan Documents merge into the Loan Documents.

12.8Counterparts. This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, is an original, and all taken together, constitute one Agreement. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic method of

18

transmission (including .pdf format) shall be effective as delivery of a manually executed original counterpart of this Agreement.

12.9[Reserved].

12.10Electronic Execution of Documents. The words “execution,” “signed,” “signature” and words of like import in any Loan Document shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity and enforceability as a manually executed signature or the use of a paper-based recordkeeping systems, as the case may be, to the extent and as provided for in any applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act.

12.11Right of Setoff. If an Event of Default shall have occurred and be continuing, Lender shall be entitled to setoff as security for all Obligations to Lender, whether now existing or hereafter arising upon and against all accounts payable and other liabilities of Lender to any Loan Party, together with all deposits, credits, collateral and property, now or hereafter in the possession, custody, safekeeping or control of Lender or any entity under the control of Lender (including a subsidiary of Lender) or in transit to any of them. At any time after the occurrence and during the continuance of an Event of Default, without demand or notice, Lender may setoff the same or any part thereof and apply the same to any liability or Obligation of Borrower even though unmatured and regardless of the adequacy of any other collateral securing the Obligations. ANY AND ALL RIGHTS TO REQUIRE LENDER TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF ANY LOAN PARTY, ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.

12.12Captions. The headings used in this Agreement are for convenience only and shall not affect the interpretation of this Agreement.

12.13Construction of Agreement. The parties mutually acknowledge that they and their attorneys have participated in the preparation and negotiation of this Agreement. In cases of uncertainty this Agreement shall be construed without regard to which of the parties caused the uncertainty to exist.

12.14Relationship. The relationship of the parties to this Agreement is determined solely by the provisions of this Agreement. The parties do not intend to create any agency, partnership, joint venture, trust, fiduciary or other relationship with duties or incidents different from those of parties to an arm’s-length contract.

12.15Third Parties. Nothing in this Agreement, whether express or implied, is intended to: (a) confer any benefits, rights or remedies under or by reason of this Agreement on any Persons other than the express parties to it and their respective permitted successors and assigns; (b) relieve or discharge the obligation or liability of any Person not an express party to

19

this Agreement; or (c) give any Person not an express party to this Agreement any right of subrogation or action against any party to this Agreement.

12.16Waiver of Redemption, Notice and Marshaling of Assets. To the fullest extent permitted by law, each Loan Party hereby irrevocably and unconditionally waives and releases (a) all benefit that might accrue to such Loan Party by virtue of any present or future statute of limitations or law or judicial decision exempting the Collateral from attachment, levy or sale on execution or providing for any appraisement, valuation, stay of execution, exemption from civil process, redemption or extension of time for payment, (b) all notices of any Event of Default or of Lender’s election to exercise or the actual exercise of any right, remedy or recourse provided for under the Loan Documents (other than any notices required to be given by Lender under the Loan Documents), and (c) any right to a marshaling of assets or a sale in inverse order of alienation.

12.17Discontinuance of Proceedings. If Lender shall have proceeded to invoke any right, remedy or recourse permitted under the Loan Documents and shall thereafter elect to discontinue or abandon it for any reason, Lender shall have the unqualified right to do so and, in such an event, Lender shall be restored to its former position with respect to the Obligations, the Loan Documents, the Collateral and otherwise, and the rights, remedies, recourses and powers of Lender shall continue as if the right, remedy or recourse had never been invoked, but no such discontinuance or abandonment shall waive any Event of Default which may then exist or the right of Lender thereafter to exercise any right, remedy or recourse under the Loan Documents for such Event of Default. Each Loan Party hereby expressly waives any and all rights and benefits such Loan Party may have to claim or assert that the Obligations have been reinstated in accordance with their terms following the withdrawal of any proceedings by Lender, and acknowledges and agrees that reinstatement shall occur only upon written agreement of Lender.

12.18Waiver of Stay, Moratorium and Similar Rights. Each Loan Party agrees, to the full extent that it may lawfully do so, that it will not at any time insist upon or plead or in any way take advantage of any appraisement, valuation, stay, marshaling of assets, extension, redemption or moratorium law now or hereafter in force and effect so as to prevent or hinder the enforcement of the provisions of this Agreement or the Indebtedness secured hereby, or any agreement between such Loan Party and Lender or any rights or remedies of Lender, or any one or more of them.

12.19Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to the Loans, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by Lender in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate. Anything in this Agreement or any other Loan Document to the contrary notwithstanding, Borrower shall not be required to pay interest at a rate in excess of the Maximum Rate, and if the effective rate of interest which would otherwise be payable under this Agreement and the other Loan Documents would exceed the Maximum Rate, or if Lender shall receive monies that are deemed to constitute interest which would increase the effective rate of interest payable by Borrower under this Agreement or Loan Document to a rate in excess of the Maximum Rate, then (a) the amount of interest which would

20

otherwise be payable by Borrower under this Agreement or any Loan Document shall be reduced to the amount allowed under applicable law, and (b) any interest paid by Borrower in excess of the Maximum Rate shall be credited on the principal of the Loan (or, if the principal amount of the Loan shall have been paid in full, refunded to Borrower). It is further agreed that, without limitation of the foregoing, all calculations of the rate of interest contracted for, charged or received by Lender under this Agreement or any Loan Document, are made for the purpose of determining whether such rate exceeds the Maximum Rate, and shall be made by amortizing, prorating and spreading in equal parts during the period of the full stated term of the Loan all interest at any time contracted for, charged or received by Lender in connection therewith.

13.GUARANTEE

13.1Guarantee.

(a)Subject to the provisions of Section 13.1(b), each Guarantor hereby unconditionally and irrevocably, jointly and severally, guarantees to Lender and its successors, indorsees, transferees and assigns, the prompt and complete payment and performance by the Loan Parties when due and payable (whether at the stated maturity, by acceleration or otherwise) of the Obligations. The guarantee of each Guarantor in this Section 13 is a guarantee of payment and not a guarantee of collection.

(b)Anything herein or in any other Loan Document to the contrary notwithstanding, the maximum liability of each Guarantor hereunder and under the other Loan Documents shall in no event exceed the amount which can be guaranteed by such Guarantor under applicable federal or state laws, statutes or regulations relating to the insolvency of debtors or fraudulent transfers.

(c)Each Guarantor agrees that the Obligations may at any time and from time to time exceed the amount of the liability of such Guarantor hereunder without impairing the guarantee contained in this Section 13 or affecting the rights and remedies of Lender hereunder.

(d)The guarantee of each Guarantor contained in this Section 13 shall remain in full force and effect until all Obligations are repaid in full in cash and this Agreement is terminated.

(e)No payment made by Borrower or any other Person or received or collected by Lender from Borrower or any other Person by virtue of any action or proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in payment of the Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of any Guarantor hereunder which shall, notwithstanding any such payment (other than any payment made by such Guarantor in respect of the Obligations or any payment received or collected from such Guarantor in respect of the Obligations), remain liable for the Obligations up to the maximum liability of such Guarantor hereunder until all Obligations are repaid in full in cash and this Agreement is terminated.

13.2No Subrogation. Notwithstanding any payment made by any Guarantor hereunder or any set-off or application of funds of any Guarantor by Lender, no Guarantor shall be entitled to be subrogated to any of the rights of Lender against Borrower or any collateral security or guarantee or right of offset held by Lender for the payment of the Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from Borrower or in respect of payments made by any Guarantor hereunder, until all Obligations are repaid in full in

21

cash and this Agreement is terminated. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time prior to all Obligations being repaid in full in cash and this Agreement being terminated, such amount shall be held by such Guarantor in trust for Lender segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to Lender in the exact form received by such Guarantor (duly indorsed by such Guarantor to Lender, if required), to be applied against the Obligations, whether matured or unmatured, in accordance with the terms of the Loan Documents.

13.3Amendments, etc. with respect to the Obligations. Each Guarantor shall remain obligated hereunder notwithstanding that, without any reservation of rights against such Guarantor and without notice to or further assent by such Guarantor, any demand for payment of any of the Obligations made by Lender may be rescinded by Lender and any of the Obligations continued, and the Obligations, or the liability of any other Person upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by Lender and this Agreement and the other Loan Documents and any other documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as Lender and Borrower may deem advisable from time to time, and any collateral security, guarantee or right of offset at any time held by Lender for the payment of the Obligations may be sold, exchanged, waived, surrendered or released.

13.4Guarantee Absolute and Unconditional. Each Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Obligations and notice of or proof of reliance by Lender upon the guarantee contained in this Section 13 or acceptance of the guarantee contained in this Section 13; the Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon the guarantee contained in this Section 13; and all dealings between the Loan Parties, on the one hand, and Lender on the other hand, like-wise shall be conclusively presumed to have been had or consummated in reliance upon the guarantee contained in this Section 13. To the fullest extent permitted by applicable law, each Guarantor waives diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon Borrower with respect to the Obligations, other than any notices specifically required by Lender hereunder. Each Guarantor understands and agrees that the guarantee contained in this Section 13 shall be construed as a continuing, absolute and unconditional guarantee of payment without regard to (a) the validity or enforceability of this Agreement or any other Loan Document, any of the Obligations owing by Borrower or any other collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by Lender, (b) any defense, set-off or counterclaim (other than a defense of payment or performance) which may at any time be available to or be asserted by Borrower or any other Person against Lender or (c) any other circumstance whatsoever (with or without notice to or knowledge of Borrower) which constitutes, or might be construed to constitute, an equitable or legal discharge of the Loan Parties for the Obligations, or of such Guarantor under the guarantee contained in this Section 13, in bankruptcy or in any other instance (other than a defense of payment or performance). When making any demand hereunder or otherwise pursuing its rights and remedies hereunder against any Guarantor, Lender may, but shall be under no obligation to, make a similar demand on or otherwise pursue such rights and remedies as it may have against Borrower or any other

22

Person or against any collateral security or guarantee for the Obligations or any right of offset with respect thereto, and any failure by Lender to make any such demand, to pursue such other rights or remedies or to collect any payments from Borrower or any other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of Borrower or any other Person or any such collateral security, guarantee or right of offset, shall not relieve any Guarantor of any obligation or liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of Lender against any Guarantor. For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings.

13.5Reinstatement. The guarantee contained in this Section 13 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 Lender upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of Borrower or any Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, Borrower or any Guarantor or any substantial part of its property, or otherwise, all as though such payments had not been made.

13.6Payments. Each Guarantor hereby guarantees that payments hereunder will be paid to Lender without set-off or counterclaim in Dollars at Lender’s office.
