(a)                                  Original Borrower agrees to indemnify, defend and hold Lender harmless against any loss, claim, damage, liability or expense (including, without limitation, reasonable attorney’s fees) incurred as a result of any representation or warranty made by it herein proving to be untrue in any respect.

(b)                                 Borrower agrees to indemnify, defend and hold Lender harmless against any loss, claim, damage, liability or expense (including, without limitation, reasonable attorney’s fees) incurred as a result of any representation or warranty made by it herein proving to be untrue in any respect. If Borrower shall fail to keep or perform any of the covenants or agreements contained herein beyond any applicable notice, grace and cure periods, or if any statement, representation or warranty contained herein by Borrower is false, misleading or erroneous in any material respect when made, it shall constitute a default under the Loan Documents and Lender shall be entitled at its option to exercise any and all of the rights and remedies granted pursuant to the Deed of Trust or any other Loan Documents or which Lender may otherwise be entitled, whether at law or in equity.

12.                                 Notices. All notices or other communications required or permitted to be given pursuant to this Agreement shall be in writing and shall be considered as properly given if (i) mailed by first class United States mail, postage prepaid, registered or certified with return receipt requested; (ii) by delivering same in person to the intended addressee; or (iii) by delivery to an independent third party commercial delivery service for same day or next day delivery and providing for evidence of receipt at the office of the intended addressee. Notice so mailed shall be effective upon its deposit with the United States Postage Service or any successor thereto; notice sent by a commercial delivery service shall be effective upon delivery to such commercial delivery service; notice given by personal delivery shall be effective only if and when received by the addressee; and notice given by other means shall be effective only if and when received at the designated address of the intended addressee. For purposes of notice, the addresses of the parties shall be as set forth below:

12

Any party shall have the right to change its address for notice hereunder to any other location within the continental United States by the giving of 30 days notice to the other party in the manner set forth above.

13.                                 Further Assurances. Original Borrower and Borrower, upon request from Lender, each agree to execute such other and further documents as may be reasonably necessary or appropriate to consummate the transactions contemplated herein or to perfect the liens and security interests intended to secure the payment of the Indebtedness.

14.                                 Ratification of Loan Documents. Except as provided herein, the terms and provisions of the Loan Documents shall remain unchanged and shall remain in full force and effect. 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

13

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

14

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.
