No notice to or demand on Borrower in any case shall, of itself, entitle Borrower to any other or future notice or demand in similar or other circumstances.

Amendment. No modification, consent, amendment or waiver of any provision of this Agreement, nor consent to any departure by Borrower herefrom, shall be effective unless the same shall (i) be in writing, (ii) be specifically referenced as a modification and/or amendment, (iii) specifically set out the modification and amendment and (iv) be signed by an officer of Lender and an authorized representative for Borrower, and then shall be effective only in the specified instance and for the purpose for which given. This Agreement is binding upon

Borrower, its successors and assigns, and inures to the benefit of Lender, its successors and assigns; provided, however, no assignment or other transfer of Borrower’s rights or obligations hereunder shall be made or be effective without Lender’s prior written consent, nor shall it relieve Borrower of any obligations hereunder. There is no third-party beneficiary of this Loan Agreement.

c. Documents. All documents, certificates and other items required under this Agreement to be executed and/or delivered to Lender shall be in form and content reasonably satisfactory to Lender and its counsel.

d. Partial Invalidity. The unenforceability or invalidity of any provision of this Agreement shall not affect the enforceability or validity of any other provision hereof and the invalidity or unenforceability of any provision of any Loan Document to any person or circumstance shall not affect the enforceability or validity of such provision as it may apply to other persons or circumstances.

e. INDEMNIFICATION. Borrower shall indemnify, defend and hold Lender and its successors and assigns harmless from and against any and all claims, demands, suits, losses, damages, assessments, fines, penalties, costs or other reasonable and documented out-of-pocket expenses (including reasonable and documented attorneys’ fees and court costs) arising from or in any way related to any of the transactions contemplated hereby, including but not limited to actual or threatened damage to the environment, agency costs of investigation, personal injury or death, or Property damage, due to a release or alleged release of Hazardous Materials, arising from Borrower’s business operations, any other Property owned by Borrower or in the surface or ground water arising from Borrower’s business operations, or gaseous emissions arising from Borrower’s business operations or any other condition existing or arising from Borrower’s business operations resulting from the use or existence of Hazardous Materials, whether such claim proves to be true or false. Borrower further agrees that its indemnity obligations shall include, but are not limited to, liability for damages resulting from the personal injury or death of an employee of Borrower, regardless of whether Borrower has paid the employee under the workmen’s compensation laws of any state or other similar federal or state legislation for the protection of employees. The term “Property damage” as used in this paragraph includes, but is not limited to, damage to any real or personal property of Borrower, Lender, and of any third parties. Borrower’s obligations under this paragraph shall survive the repayment of the Loan and any deed in lieu of foreclosure or foreclosure of any deed to secure debt, Deeds of Trust, Security Agreement or mortgage securing the Loan; provided, however, in no event shall Borrower be liable to Lender or its successors or assigns for any claims, demands, suits, losses, damages, assessments, fines, penalties, costs or other reasonable and documented out-of-pocket expenses (including reasonable and documented out-of-pocket attorneys’ fees and court costs) arising from the Lender’s, its successors’ or assigns’ gross negligence, bad faith, willful misconduct or breach of its obligations under the Loan Documents.

f. Survivability. All covenants and agreements made herein or in the other Loan Documents shall survive the making of the Loan and shall continue in full force and effect so long as the Loan is outstanding or any renewals, extensions and amendments thereto shall not have expired.

g. Conflicts. In the event there exists any conflicts or inconsistencies between the terms of this Agreement and the terms of the other Loan Documents, the terms of this Agreement shall govern and control provided.

h. Attorney’s Fees. If, as a result of a breach of this Agreement by either party, the other party employs an attorney or attorneys to enforce its rights under the Loan Documents, then, and in such event, the party which does not prevail in full in any such action or litigation, i.e. the non-prevailing party, shall be required to pay the prevailing party in such action or litigation the reasonable and documented out-of-pocket attorneys’ fees and costs incurred by such prevailing party in the conduct of such action or litigation.

15. RENEWAL, EXTENSION OR REARRANGEMENT. All provisions of this Agreement and any of the other Security Documents relating to the Advance Type/Term Note or any other Indebtedness shall apply with equal force and effect to any renewal or extension hereof, including for any increase, rearrangement or refinancing of any part of the Indebtedness.

16. SETOFF. Upon the occurrence and during the continuance of any Event of Default, Lender is hereby authorized at any time and from time to time, without notice to Borrower (any such notice being expressly waived by Borrower), to set-off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by Lender to or for the credit or the account of Borrower against any and all of the Indebtedness, irrespective of whether or not Lender shall have made any demand under the Loan Documents and although such Indebtedness may be unmatured. Any amount set-off by Lender shall be applied against the Indebtedness. Lender agrees promptly to notify Borrower after any such setoff and application; provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of Lender under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) which Lender may have.

17. CHOICE OF FORUM: CONSENT TO SERVICE OF PROCESS AND JURISDICTION; CHOICE OF LAW. THE OBLIGATIONS OF BORROWER UNDER THE LOAN DOCUMENTS ARE PERFORMABLE IN MIDLAND COUNTY, TEXAS. ANY SUIT, ACTION OR PROCEEDING AGAINST BORROWER WITH RESPECT TO THE LOAN DOCUMENTS OR ANY JUDGMENT ENTERED BY ANY COURT IN RESPECT THEREOF, MAY BE BROUGHT IN THE COURTS OF THE STATE OF TEXAS, COUNTY OF MIDLAND, OR IN THE UNITED STATES COURTS LOCATED IN MIDLAND COUNTY, TEXAS AND BORROWER HEREBY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF SUCH COURTS FOR THE PURPOSE OF ANY SUCH SUIT, ACTION OR PROCEEDING. BORROWER HEREBY IRREVOCABLY CONSENTS TO SERVICE OF PROCESS IN ANY SUIT, ACTION OR PROCEEDING IN SAID COURT BY THE MAILING THEREOF BY LENDER BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO BORROWER, AT THE ADDRESS FOR NOTICES AS PROVIDED ABOVE. BORROWER HEREBY IRREVOCABLY WAIVES ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENT BROUGHT IN THE COURTS LOCATED IN THE STATE OF TEXAS, COUNTY OF MIDLAND, AND HEREBY FURTHER IRREVOCABLY WAIVES ANY CLAIM THAT ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. THIS AGREEMENT AND EACH OTHER LOAN DOCUMENT, AND ALL MATTERS RELATING HERETO OR THERETO OR ARISING THEREFROM (WHETHER SOUNDING IN CONTRACT LAW, TORT LAW OR OTHERWISE), SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES, EXCEPT TO THE EXTENT THAT UNITED STATES FEDERAL LAW PERMITS ANY LENDER TO CHARGE INTEREST AT THE RATE ALLOWED BY THE LAWS OF THE STATE WHERE SUCH LENDER IS LOCATED. CH. 346 OF THE TEXAS FINANCE CODE (WHICH REGULATES CERTAIN REVOLVING CREDIT LOAN ACCOUNTS AND REVOLVING TRI-PARTY ACCOUNTS) SHALL NOT APPLY TO THIS AGREEMENT OR THE NOTES.

18. WAIVER OF JURY TRIAL. EACH PARTY TO THIS AGREEMENT HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR (2) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR ANY OF THEM WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING AND WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A

JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

19. NO ORAL AGREEMENT. THIS AGREEMENT AND THE OTHER 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.

20. Confidentiality. In handling any confidential information, Lender and all employees and agents of Lender, including but not limited to accountants, shall exercise the same degree of care that it exercises with respect to its own proprietary information of the same types to maintain the confidentiality of any non-public information thereby received or received pursuant to this Agreement except that disclosure of such information may be made (a) to the subsidiaries or Affiliates of Lender in connection with their present or prospective business relations with Borrower (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such information and instructed to keep such information confidential), (b) subject to an agreement containing provisions substantially the same as those of this Section 20, to prospective transferees or purchasers of any interest in the loans, (c) as required by law, regulations, rule or order, subpoena, judicial order, or similar order (in which case Lender shall inform Borrower promptly thereof prior to such disclosure to the extent permitted by applicable law and shall use commercially reasonable efforts to ensure that any information so disclosed is accorded confidential treatment), (d) on a confidential basis, as may be required in connection with the examination, audit, or similar investigation of Lender, and (e) as Lender may determine in connection with the enforcement of any remedies hereunder. Confidential information hereunder shall not include information that either: (x) is in the public domain or in the knowledge or possession of Lender when disclosed to Lender, or becomes part of the public domain after disclosure to Lender through no fault of Lender; or (y) is disclosed to Lender by a third party, provided that Lender does not have actual knowledge that such third party is prohibited from disclosing such information.
