Article Two

Commitment to Lend, Terms of Payment

2.1 Revolving Loan. Subject to and upon the terms, covenants, and conditions of this Agreement, Bank agrees to make one or more Advances (hereinafter called the “Revolving Loan”) to Borrower for Approved Purposes in an aggregate principal amount at any one time outstanding up to but not exceeding the Borrowing Limit. Within the limit of the Borrowing Limit in effect from time to time, Borrower may borrow, repay, and reborrow at any time and from time to time from the Closing Date to the earlier of (a) the maturity of the Revolving Note, or (b) the termination of Bank’s Commitment hereunder. If, by virtue of payments made on the Revolving Note, the principal amount owed on the Revolving Note during its term reaches zero at any point, Borrower agrees that all of the Collateral and all of the Loan Documents shall remain in full force and effect to secure any Advances made thereafter, and Bank shall be fully entitled to rely on all of the Collateral and all of the Loan Documents unless an appropriate release of all or any part of the Collateral or all or any part of the Loan Documents has been executed by Bank. The Revolving Principal Balance may not exceed the Borrowing Limit at any time.

2.2 Revolving Note. The Revolving Loan shall be evidenced by, and be repayable in accordance with the Revolving Note.

2.3 Revolving Loan Borrowing Procedure. Borrower shall give Bank notice of each Revolving Loan by means of a written request containing the information required by Bank and delivered (by hand or by mechanically confirmed facsimile) to Bank no later than 10:00 a.m. (Dallas, Texas time) on the day on which the Revolving Loan is desired to be funded. Bank, at its option, may accept telephonic requests for such Advances, provided that such acceptance shall not constitute a waiver of Bank’s right to require delivery of a written request in connection with subsequent Revolving Loan. Any telephonic request for a Revolving Loan by Borrower shall be promptly confirmed by submission of a properly completed written request to Bank, but failure to deliver a written request shall not be a defense to payment of a Revolving Loan. Bank shall have no liability to Borrower for any loss or damage suffered by Borrower as a result of Bank’s honoring of any requests, execution of any instructions, authorizations or agreements or reliance on any reports communicated to it telephonically, by facsimile or electronically, and purporting to have been sent to Bank by Borrower and Bank shall have no duty to verify the origin of any such communication or the identity or authority of the Person sending it. Subject to the terms and conditions of this Agreement, each Revolving Loan shall be made available to Borrower by depositing the same, in immediately available funds, in an account of Borrower designated by Borrower maintained with Bank. To automate the Revolving Loan notification process, Borrower shall enter into a “Credit Sweep” facility or “loan manager” in connection with the Commitment and Borrower’s deposit accounts maintained with Bank.

2.4 Payments. Borrower authorizes Bank to auto debit the amount of any scheduled payment under the Revolving Note when due from any deposit account or other account of Borrower with Bank.

2.5 Prepayments.

(a) Voluntary Prepayments. The Borrower may prepay all or any portion of the Note to the extent and in the manner provided for therein.

(b) Mandatory Prepayment. The Borrower must immediately upon written notice of DEMAND pay the amount by which at any time the unpaid principal balance of the Revolving Loan exceeds the Borrowing Limit; provided, that if such excess is directly caused by a default of one or more Guarantors under a Guaranty Agreement or other Loan Document and the amount of such excess is less than $350,000.00, Borrower shall have thirty (30) days from the date of such notice to pay such excess amount or cause the replacement of the defaulting Guarantor with another Guarantor subject to documents and terms satisfactory to Bank.

2.6 Purpose of Loans. Borrower represents that the proceeds of the Revolving Loan will be used only for Approved Purposes.

2.7 Sale of Participations. Bank may, from time to time, sell or offer to sell the Indebtedness, or interests therein, to one or more participants and Bank is hereby authorized to disseminate and disclose any information (whether or not confidential or proprietary in nature) Bank now has or may hereafter obtain pertaining to Borrower, the Indebtedness or the Loan Documents (including, without limitation, any credit or other information regarding Borrower, any of its principals, or any other person or entity liable, directly or indirectly, for any part of the Loan, to (a) any participant or prospective participant, (b) any regulatory body having jurisdiction over Bank or the Indebtedness, and (c) any other persons or entities as may be necessary or appropriate in Bank’s reasonable judgment); provided, that, so long as no Event of Default has occurred, Bank shall be required to obtain the prior written consent of Borrower prior to entering into any such participation. Following the occurrence of an Event of Default, Bank, as a courtesy to Borrower, will endeavor to notify Borrower of any participants or prospective participants, to which Bank disseminates any of the information described above.

2.8 Order of Application. Except as otherwise provided in the Loan Documents or otherwise agreed by Bank, all payments and prepayments of the Indebtedness, including proceeds from the exercise of any Rights under the Loan Documents or proceeds of any of the Collateral, shall be applied to the Indebtedness in the following order, any instructions from Borrower to the contrary notwithstanding: (a) to the expenses for which Bank shall not have been reimbursed under the Loan Documents, and then to all indemnified amounts due under the Loan Documents; (b) to fees then owed Bank hereunder; (c) to accrued interest on the portion of the Indebtedness being paid or prepaid; (d) to the portion of the principal being paid or prepaid; (e) to the remaining accrued interest on the Indebtedness; (f) to the remaining principal; and (g) to the remaining Indebtedness. All amounts remaining after the foregoing application of funds shall be paid to Borrower.

2.9 Commitment Fee. Borrower shall pay to Bank a Commitment Fee of $25,000.00 on the date hereof. Such fee, as of the date of this Agreement, is fully earned and non-refundable.

2.10 Lockbox and Account Collections. Borrower will maintain under such written agreements as Bank requires, as security for the Indebtedness, a depository account with the Bank (“Depository Account”) and, upon request of Bank following an Event of Default, a lockbox (“Lockbox”). Upon the request of Bank following the occurrence of an Event of Default, Borrower will advise all of its account debtors to direct their payments to the Lockbox, at the address established by the Lockbox arrangements; all payments received into the Lockbox will be deposited into the Depository Account; and all payments from account debtors of Borrower not otherwise delivered to the Lockbox will be deposited directly into the Depository Account, and Bank is authorized to transfer to the Depository Account any funds which are account debtor payments but which have been deposited into any other depository account of Borrower at Bank. Upon the occurrence of an Event of Default, Borrower agrees that Bank will have all right, title and interest in and to all items and funds from time to time in the Depository Account. Checks received into the Depository Account will not be considered good funds until Bank has effected final settlement with respect thereto. After an Event of Default has occurred, Bank is authorized to apply any and all funds in the Depository Account at any time, and from time to time, to the Indebtedness (to the extent then due and payable) in any order Bank may elect.

2.11 Letters of Credit. Subject to the terms and conditions of this Agreement and other Loan Documents, Bank may, in its reasonable discretion, issue one or more Letters of Credit for the account of Borrower from time to time. No Letter of Credit shall have an expiration date less than thirty (30) days before the Maturity Date of the Revolving Note unless Borrower provides cash Collateral satisfactory to Bank to secure any such Letter of Credit. Each Letter of Credit (i) must be satisfactory in form and substance to Bank, (ii) will be subject to the payment of such Letter of Credit fees as Bank may require, and (iii) shall be issued pursuant to such conditions, documents and instruments agreed to and/or executed by Borrower as Bank may require in its sole discretion. Each payment by Bank pursuant to a drawing under a Letter of Credit is due and payable ON DEMAND, and at the sole option of Bank, can be charged by Bank as a Revolving Loan by Bank to Borrower under the Revolving Note and this Agreement as of the day and time such payment is made by Bank and in the amount of such payment.

5.4 Compliance with Laws and Documents. Borrower is not, nor will the execution, delivery, and performance of and compliance with the terms of the Loan Documents cause Borrower to be, in violation of any Laws or in default (nor has any event occurred which, with notice or lapse of time or both, could constitute such a default) under any contract in any respect which could have a Material Adverse Effect. During the past five (5) years, there have been no proceedings, claims, or (to Borrower’s knowledge) investigations against or involving Borrower by any Tribunal, including under or pursuant to any environmental, occupational safety and health, antitrust, unfair competition, securities, or other Laws which could have a Material Adverse Effect, except those described on Schedule Two attached hereto (the “Tribunal Proceedings”).

Except for Litigation in which Borrower is exclusively a plaintiff without a counterclaim, crossclaim, or similar action asserted against Borrower and except as set forth on Schedule Two attached hereto (the “Existing Litigation”), Borrower is not involved in, nor is Borrower aware of the threat of, any Litigation which could have a Material Adverse Effect, and there are no outstanding or unpaid judgments against Borrower (the “Unpaid Judgments”).

5.9 Regulation U. The proceeds of the Advances are not and will not be used directly or indirectly for the purpose of purchasing or carrying, or for the purpose of extending credit to others for the purpose of purchasing or carrying, any “margin stock” as that term is defined in Regulation U of the Board of Governors of the Federal Reserve System.

5.10 Subsidiaries. Borrower has no Subsidiaries as of the date of this Agreement except those described on Schedule Two.

At any time an Event of Default exists, Bank shall be entitled to exercise the Rights of setoff and/or banker’s lien against the interest of Borrower in and to each and every account and other property of Borrower which are in the possession of Bank to the extent of the full amount of the Indebtedness.

10.3 Performance by Bank. Should any covenant, duty, or agreement of Borrower fail to be performed in accordance with the terms of the Loan Documents, Bank may, at its option, perform or attempt to perform, such covenant, duty, or agreement on behalf of Borrower. In such event, or if Bank expends any sum pursuant to the exercise of any Right provided herein, Borrower shall, at the request of Bank, promptly pay to Bank any amount expended by Bank in such performance or attempted performance, together with interest thereon at the Maximum Rate from the date of such expenditure by Bank until paid. Notwithstanding the foregoing, it is expressly understood that Bank does not assume any liability or responsibility for the performance of any duties of Borrower hereunder or in connection with all or any part of the Collateral.

10.4 Diminution in Collateral Value. Bank does not assume, and shall never have, any liability or responsibility for any loss or diminution in the value of all or any part of the Collateral.

10.5 Bank Not In Control. None of the covenants or other provisions contained in this Agreement shall, or shall be deemed to, give Bank the Right to exercise control over the affairs and/or management of Borrower, the power of Bank being limited to the Right to exercise the remedies provided in the other Sections of this Article; provided that, if Bank becomes the owner of any ownership interest of any Person, whether through foreclosure or otherwise, Bank shall be entitled to exercise such legal Rights as it may have by virtue of being an owner of such Person.

10.6 Waivers. The acceptance of Bank at any time and from time to time of part payment on the Indebtedness shall not be deemed to be a waiver of any Event of Default then existing. No waiver by Bank of any Event of Default shall be deemed to be a waiver of any other then-existing or subsequent Event of Default. No waiver by Bank of any of its Rights hereunder, in the other Loan Documents, or otherwise shall be considered a waiver of any other or subsequent Right of Bank. No delay or omission by Bank in exercising any Right under the Loan Documents shall impair such Right or be construed as a waiver thereof or any acquiescence therein, nor shall any single or partial exercise of any such Right preclude other or further exercise thereof, or the exercise of any other Right under the Loan Documents or otherwise.

10.7 Cumulative Rights. All Rights available to Bank under the Loan Documents shall be cumulative of and in addition to all other Rights granted to Bank at Law or in equity, whether or not the Obligations be due and payable and whether or not Bank shall have instituted any suit for collection, foreclosure, or other action under or in connection with the Loan Documents.

10.8 INDEMNIFICATION OF BANK. BORROWER SHALL INDEMNIFY BANK AND EACH AFFILIATE THEREOF AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, ATTORNEYS, AND AGENTS FROM, AND HOLD EACH OF THEM HARMLESS AGAINST, ANY AND ALL LOSSES, LIABILITIES, CLAIMS, DAMAGES, PENALTIES, JUDGMENTS, DISBURSEMENTS, COSTS, AND EXPENSES (INCLUDING REASONABLE ATTORNEYS’ FEES) TO WHICH ANY OF THEM MAY BECOME SUBJECT WHICH DIRECTLY OR INDIRECTLY ARISE FROM OR RELATE TO (A) THE NEGOTIATION, EXECUTION, DELIVERY, PERFORMANCE, ADMINISTRATION, OR ENFORCEMENT OF ANY OF THE LOAN DOCUMENTS, (B) ANY OF THE TRANSACTIONS CONTEMPLATED BY THE LOAN DOCUMENTS, (C) ANY BREACH BY BORROWER OF ANY REPRESENTATION, WARRANTY, COVENANT, OR OTHER AGREEMENT CONTAINED IN ANY OF THE LOAN DOCUMENTS, (D) THE PRESENCE, RELEASE, THREATENED RELEASE, DISPOSAL, REMOVAL, OR CLEANUP OF ANY HAZARDOUS MATERIAL LOCATED ON, ABOUT, WITHIN OR AFFECTING ANY OF THE PROPERTIES OR ASSETS OF THE BORROWER OR ANY SUBSIDIARY, (E) THE USE OR PROPOSED USE OF ANY LETTER OF CREDIT, (F) ANY AND ALL TAXES, LEVIES, DEDUCTIONS, AND CHARGES IMPOSED ON BANK OR ANY OF BANK’S CORRESPONDENTS IN RESPECT OF ANY LETTER OF CREDIT, OR (G) ANY INVESTIGATION, LITIGATION, OR OTHER PROCEEDING, INCLUDING, WITHOUT LIMITATION, ANY THREATENED INVESTIGATION, LITIGATION, OR OTHER PROCEEDING, RELATING TO ANY OF THE FOREGOING. WITHOUT LIMITING ANY PROVISION OF THIS AGREEMENT OR OF ANY OTHER LOAN DOCUMENT, IT IS THE EXPRESS INTENTION OF THE PARTIES HERETO THAT EACH PERSON TO BE INDEMNIFIED UNDER THIS SECTION SHALL BE INDEMNIFIED FROM AND HELD HARMLESS AGAINST ANY AND ALL LOSSES, LIABILITIES, CLAIMS, DAMAGES, PENALTIES, JUDGMENTS, DISBURSEMENTS, COSTS, AND EXPENSES (INCLUDING REASONABLE ATTORNEYS’ FEES) ARISING OUT OF OR RESULTING FROM THE SOLE CONTRIBUTORY OR ORDINARY NEGLIGENCE OF SUCH PERSON; PROVIDED, HOWEVER, THE INDEMNITIES PROVIDED IN THIS SECTION 10.8 DO NOT EXTEND TO LOSSES, LIABILITIES, CLAIMS, OR DAMAGES CAUSED BY BANK’S GROSS NEGLIGENCE OR MISCONDUCT.

10.9 Limitation of Liability. Neither Bank nor any Affiliate, officer, director, employee, attorney, or agent of Bank shall have any liability with respect to, and Borrower hereby waives, releases, and agrees not to xxx any of them upon, any claim for any special, indirect, incidental, or consequential damages suffered or incurred by the Borrower in connection with, arising out of, or in any way related to, this Agreement or any of the other Loan Documents, or any of the transactions contemplated by this Agreement or any of the other Loan Documents. Borrower hereby waives, releases, and agrees not to xxx Bank or any of Bank’s Affiliates, officers, directors, employees, attorneys, or agents for punitive damages in respect of any claim in connection with, arising out of, or in any way related to, this Agreement or any of the other Loan Documents, or any of the transactions contemplated by this Agreement or any of the other Loan Documents.

Article Eleven

Miscellaneous

11.1 Headings. The headings, captions, and arrangements used in any of the Loan Documents are, unless specified otherwise, for convenience only and shall not be deemed to limit, amplify, or modify the terms of the Loan Documents, nor affect the meaning thereof.

11.2 Notices. Unless otherwise expressly provided herein, all notices and other communications provided for hereunder shall be in writing (including by facsimile transmission) and mailed, faxed, or delivered, to the address or facsimile number to the address specified for notices on the signature page below, or to such other address as shall be designated by such party in a notice to the other parties. All such other notices and other communications shall be deemed to have been given or made upon the earliest to occur of (a) actual receipt by the intended recipient or (b) (i) if delivered by hand or courier, when signed for by the designated recipient; (ii) if delivered by mail, four business days after deposit in the mail, postage prepaid; and (iii) if delivered by facsimile when sent and receipt has been confirmed by telephone. Electronic mail and internet websites may be used only to distribute only routine communications, such as financial statements and other information, and to distribute Loan Documents for execution by the parties thereto, and may not be used for any other purpose.

11.3 Form and Number of Documents. Each agreement, document, instrument, or other writing to be furnished to Bank under any provision of this Agreement must be in form and substance and in such number of counterparts as may be satisfactory to Bank and its counsel.

11.4 Survival. All covenants, agreements, undertakings, representations, and warranties made in any of the Loan Documents shall survive all closings under the Loan Documents and shall continue in full force and effect so long as any part of the Indebtedness remain and, except as otherwise indicated, shall not be affected by any investigation made by any party. Notwithstanding anything contained herein to the contrary, the covenants, agreements, undertakings, representations, and warranties made in Section 6.5 and Section 10.8 shall survive the expiration or termination of this Agreement, regardless of the means of such expiration or termination.

11.5 GOVERNING LAW; PLACE OF PERFORMANCE. THE LOAN DOCUMENTS ARE BEING EXECUTED AND DELIVERED, AND ARE INTENDED TO BE PERFORMED, IN THE STATE OF TEXAS, AND THE LAWS OF SUCH STATE AND OF THE UNITED STATES SHALL GOVERN THE RIGHTS AND DUTIES OF THE PARTIES HERETO AND THE VALIDITY, CONSTRUCTION, ENFORCEMENT, AND INTERPRETATION OF THE LOAN DOCUMENTS, EXCEPT TO THE EXTENT OTHERWISE SPECIFIED IN ANY OF THE LOAN DOCUMENTS. THIS AGREEMENT, ALL OF THE OTHER LOAN DOCUMENTS, AND ALL OF THE OBLIGATIONS OF BORROWER UNDER ANY OF THE LOAN DOCUMENTS ARE PERFORMABLE IN DALLAS COUNTY, TEXAS. VENUE OF ANY LITIGATION INVOLVING THIS AGREEMENT OR ANY LOAN DOCUMENT SHALL BE MAINTAINED IN AN APPROPRIATE STATE OR FEDERAL COURT LOCATED IN DALLAS COUNTY, TEXAS, TO THE EXCLUSION OF ALL OTHER VENUES.

11.6 Maximum Interest. It is expressly stipulated and agreed to be the intent of Borrower and Bank at all times to comply strictly with the applicable Texas law governing the maximum rate or amount of interest payable on the indebtedness evidenced by any Note or any Loan Document, and the Related Indebtedness (or applicable United States federal law to the extent that it permits Bank to contract for, charge, take, reserve or receive a greater amount of interest than under Texas law). If the applicable law is ever judicially interpreted so as to render usurious any amount (a) contracted for, charged, taken, reserved or received pursuant to any Note, any of the other Loan Documents or any other communication or writing by or between Borrower and Bank related to the transaction or transactions that are the subject matter of the Loan Documents, (b) contracted for, charged, taken, reserved or received by reason of Bank’s exercise of the option to accelerate the maturity of any Note and/or any and all indebtedness paid or payable by Borrower to Bank pursuant to any Loan Document other than any Note (such other indebtedness being referred to in this Section as the “Related Indebtedness”), or (c) Borrower will have paid or Bank will have received by reason of any voluntary prepayment by Borrower of any Note, then it is Borrower’s and Bank’s express intent that all amounts charged in excess of the Maximum Rate shall be automatically canceled, ab initio, and all amounts in excess of the Maximum Rate theretofore collected by Bank shall be credited on the principal balance of any Note and (or, if any Note has been or would thereby be paid in full, refunded to Borrower), and the provisions of any Note and the other Loan Documents shall immediately be deemed reformed and the amounts thereafter collectible hereunder and thereunder reduced, without the necessity of the execution of any new document, so as to comply with the applicable law, but so as to permit the recovery of the fullest amount otherwise called for hereunder and thereunder; provided, however, if any Note has been paid in full before the end of the stated term of any such Note, then Borrower and Bank agree that Bank shall, with reasonable promptness after Bank discovers or is advised by Borrower that interest was received in an amount in excess of the Maximum Rate, either refund such excess interest to Borrower and/or credit such excess interest against such Note and/or any Related Indebtedness then owing by Borrower to Bank. Borrower hereby agrees that as a condition precedent to any claim seeking usury penalties against Bank, Borrower will provide written notice to Bank, advising Bank in reasonable detail of the nature and amount of the violation, and Bank shall have sixty (60) days after receipt of such notice in which to correct such usury violation, if any, by either refunding such excess interest to Borrower or crediting such excess interest against the Note to which the alleged violation relates and/or the Related Indebtedness then owing by Borrower to Bank. All sums contracted for, charged, taken, reserved or received by Bank for the use, forbearance or detention of any debt evidenced by any Note and/or the Related Indebtedness shall, to the extent permitted by applicable law, be amortized or spread, using the actuarial method, throughout the stated term of such Note and/or the Related Indebtedness (including any and all renewal and extension periods) until payment in full so that the rate or amount of interest on account of any Note and/or the Related Indebtedness does not exceed the Maximum Rate from time to time in effect and applicable to such Note and/or the Related Indebtedness for so long as debt is outstanding. In no event shall the provisions of Chapter 346 of the Texas Finance Code (which regulates certain revolving credit loan accounts and revolving triparty accounts) apply to any Note and/or any of the Related Indebtedness. Notwithstanding anything to the contrary contained herein or in any of the other Loan Documents, it is not the intention of Bank to accelerate the maturity of any interest that has not accrued at the time of such acceleration or to collect unearned interest at the time of such acceleration.

11.7 Ceiling Election. To the extent that Bank is relying on Chapter 303 of the Texas Finance Code to determine the Maximum Rate payable on any such Note and/or any other portion of the Indebtedness, Bank will utilize the weekly ceiling from time to time in effect as provided in such Chapter 303, as amended. To the extent federal law permits Bank to contract for, charge, take, receive or reserve a greater amount of interest than under Texas law, Bank will rely on federal law instead of such Chapter 303 for the purpose of determining the Maximum Rate. Additionally, to the extent permitted by applicable law now or hereafter in effect, Bank may, at its option and from time to time, utilize any other method of establishing the Maximum Rate under such Chapter 303 or under other applicable law by giving notice, if required, to Borrower as provided by applicable law now or hereafter in effect.

11.8 Invalid Provisions. If any provision of any of the Loan Documents is held to be illegal, invalid, or unenforceable under present or future Laws effective during the term thereof, such provision shall be fully severable, the appropriate Loan Document shall be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part thereof; and the remaining provisions thereof shall remain in full force and effect and shall not be effected by the illegal, invalid, or unenforceable provision or by its severance therefrom. Furthermore, in lieu of such illegal, invalid, or unenforceable provision, there shall be added automatically as a part of such Loan Document a provision as similar in terms to such illegal, invalid, or unenforceable provision as may be possible and be legal, valid, and enforceable.

11.9 Amendments. This Agreement may be amended only by an instrument in writing executed jointly by Borrower and Bank and supplemented only by documents delivered or to be delivered in accordance with the express terms hereof.

11.10 Multiple Counterparts; Facsimiles. This Agreement has been executed in a number of identical counterparts, each of which constitutes an original and all of which constitute, collectively, one agreement; but in making proof of this Agreement, it shall not be necessary to produce or account for more than one such counterpart. Delivery of an executed counterpart of this Agreement by facsimile shall be equally as effective as delivery of an executed original counterpart and shall constitute a covenant to deliver an executed original counterpart, but the failure to do so shall not affect the validity, enforceability and binding effect of this Agreement. The foregoing shall apply to each other Loan Document mutatis mutandis.

11.11 Parties Bound. This Agreement shall be binding upon and inure to the benefit of Borrower, Bank and their respective successors and assigns; provided that Borrower may not, without the prior written consent of Bank, assign any of its Rights, duties, or obligations hereunder. No term or provision of this Agreement shall inure to the benefit of any Person other than Borrower and Bank and their respective successors and assigns; consequently, no Person other than Borrower and Bank and their respective successors and assigns, shall be entitled to rely upon, or to raise as a defense, in any manner whatsoever, the failure of Borrower or Bank to perform, observe, or comply with any such term or provision.

11.12 Bank’s Consent or Approval. Except where otherwise expressly provided in the Loan Documents, in any instance where the approval, satisfaction, consent or the exercise of judgment of Bank is required, the granting or denial of such approval, satisfaction or consent and the exercise of such judgment shall be (a) within the sole discretion of Bank, and (b) deemed to have been given only by a specific writing intended for the purpose and executed by Bank. Each provision for consent, approval, satisfaction, inspection, review, or verification by Bank is for Bank’s own purposes and benefit only.

11.13 Loan Agreement Governs. In the event of any conflict between the terms of this Agreement and any terms of any other Loan Document, the terms of the Loan Document selected by Bank shall govern. All of the Loan Documents are by this reference incorporated into this Agreement.

11.14 WAIVER OF JURY TRIAL. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BORROWER HEREBY IRREVOCABLY AND EXPRESSLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM (WHETHER BASED UPON CONTRACT, TORT, OR OTHERWISE) ARISING OUT OF OR RELATING TO ANY OF THE LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY OR THE ACTIONS OF BANK IN THE NEGOTIATION, ADMINISTRATION, OR ENFORCEMENT THEREOF.

11.15 ENTIRE AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS CONTAIN THE FINAL, ENTIRE AGREEMENT BETWEEN THE PARTIES HERETO RELATING TO THE SUBJECT MATTER HEREOF AND THEREOF AND ALL PRIOR AGREEMENTS, WHETHER WRITTEN OR ORAL, RELATIVE HERETO AND THERETO WHICH ARE NOT CONTAINED HEREIN OR THEREIN ARE SUPERSEDED AND TERMINATED HEREBY, AND THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS MAY NOT BE CONTRADICTED OR VARIED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OR DISCUSSIONS OF THE PARTIES HERETO. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES HERETO.
