Any modification herein of any of the Loan Documents shall in no way adversely affect the security of the Deed of Trust and the other Loan Documents for the payment of the Indebtedness. The Loan Documents as modified and amended hereby are hereby ratified and confirmed in all respects. All liens, security interests, mortgages and assignments granted or created by or existing under the Loan Documents remain unchanged and continue, unabated, in full force and effect, to secure Borrower’s obligation to repay the Indebtedness.

15. No Waiver. Lender acknowledges that Lender and its agents in the past may have accepted, without exercising the remedies to which Lender was entitled, payments and performance by Borrower that constituted defaults under the Loan Documents. Borrower acknowledges that no such acceptance or grace granted by Lender or its agents in the past, or Lender’s agreement to the modifications evidenced hereby, has in any manner diminished Lender’s right in the future to insist that Borrower strictly comply with the terms of the Loan

Documents, as modified by the terms hereof. Furthermore, Borrower specifically acknowledges that any future grace or forgiveness of default by Lender shall not constitute a waiver or diminishment of any right of Lender with respect to any future default of Borrower, whether or not similar to any default with respect to which Lender has in the past chosen, or may in the future choose, not to exercise all of the rights and remedies granted to it under the Loan Documents.

16. Merger; No Prior Oral Agreements. This Agreement supersedes and merges all prior and contemporaneous promises, representations and agreements. No modification of this Agreement or any of the Loan Documents, or any waiver of rights under any of the foregoing, shall be effective unless made by supplemental agreement, in writing, executed by Lender and Borrower. Lender and Borrower further agree that this Agreement may not in any way be explained or supplemented by a prior, existing or future course of dealings between the parties or by any prior, existing, or future performance between the parties pursuant to this Agreement or otherwise.

17. Costs and Expenses. Contemporaneously with the execution and delivery hereof, Borrower shall pay, or cause to be paid, all costs and expenses incident to the preparation hereof and the consummation of the transactions specified herein, including without limitation title insurance policy endorsement charges, recording fees and fees and expenses of legal counsel to Lender.

18. Release of Lender. Original Borrower, Borrower, Original Guarantors and Guarantors each hereby release, remise, acquit and forever discharge Lender, together with its employees, agents, representatives, consultants, attorneys, fiduciaries, servants, officers, directors, partners, predecessors, successors and assigns, subsidiary corporations, parent corporations, and related corporate divisions (all of the foregoing hereinafter called the “Released Parties”), from any and all actions and causes of action, judgments, executions, suits, debts, claims, demands, liabilities, obligations, damages and expenses of any and every character, known or unknown, direct and/or indirect, at law or in equity, of whatsoever kind or nature, whether heretofore or hereafter accruing, for or because of any matter or things done, omitted or suffered to be done by any of the Released Parties prior to and including the date hereof, and in any way directly or indirectly arising out of or in any way connected to this Agreement or any of the Loan Documents, or any of the transactions associated therewith, or the Mortgaged Property, including specifically but not limited to claims of usury.

19. Severability. If any covenant, condition, or provision herein contained is held to be invalid, illegal or unenforceable by final judgment of any court of competent jurisdiction, the invalidity, illegality or unenforceability of such covenant, condition, or provision shall not in any way affect the remainder of this Agreement, which shall continue in full force and effect.

20. Time of the Essence. It is expressly agreed by the parties hereto that time is of the essence with respect to this Agreement.

21. Representation by Counsel. The parties acknowledge and confirm that each of their respective attorneys have participated jointly in the review and revision of this Agreement

and that it has not been written solely by counsel for one party. The parties hereto therefore stipulate and agree that the rule of construction to the effect that any ambiguities are to or may be resolved against the drafting party shall not be employed in the interpretation of this Agreement to favor either party against the other.

22. Governing Law. This Agreement and the rights and duties of the parties hereunder shall be governed for all purposes by the law of the State of Texas and the law of the United States applicable to transactions within said State.

23. Counterparts. This Agreement may be executed in any number of counterparts with the same effect as if all parties hereto had signed the same document. All such counterparts shall be construed together and shall constitute one instrument, but in making proof hereof it shall only be necessary to produce one such counterpart.

24. Successors and Assigns. All of the foregoing terms and provisions of this Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and assigns.

25. Recitals. The recitals contained herein are incorporated into this Agreement by reference.

26. Headings. The paragraph headings set forth in this Agreement are for the convenience of the parties only, and shall in no way enlarge or limit the scope or meaning of the various and several paragraphs in this Agreement.

27. Notice of No Oral Agreements. Borrower, Guarantors and Lender hereby take notice of and agree to the following:

A. PURSUANT TO SUBSECTION 26.02(b) OF THE TEXAS BUSINESS AND COMMERCE CODE, A LOAN AGREEMENT IN WHICH THE AMOUNT INVOLVED THEREIN EXCEEDS $50,000 IN VALUE IS NOT ENFORCEABLE UNLESS THE AGREEMENT IS IN WRITING AND SIGNED BY THE PARTY TO BE BOUND OR BY THAT PARTY’S AUTHORIZED REPRESENTATIVE.

B. PURSUANT TO SUBSECTION 26.02(c) OF THE TEXAS BUSINESS AND COMMERCE CODE, THE RIGHTS AND OBLIGATIONS OF THE PARTIES TO THE LOAN DOCUMENTS SHALL BE DETERMINED SOLELY FROM THE LOAN DOCUMENTS, AND ANY PRIOR ORAL AGREEMENTS BETWEEN THE PARTIES ARE SUPERSEDED BY AND MERGED INTO THE LOAN DOCUMENTS.

C. THE LOAN DOCUMENTS AND THIS AGREEMENT REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES THERETO AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES THERETO. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

IN WITNESS WHEREOF, this Agreement is executed effective as of the date first above written.
