NOW, THEREFORE, as an inducement to Bank to make certain loans to Borrower, and to extend such additional credit as Bank may from time to time agree to extend, and for other good and valuable consideration, the receipt and legal sufficiency of which are hereby acknowledged, Guarantor, jointly and severally, hereby agrees as follows: AGREEMENTS ARTICLE I NATURE AND SCOPE OF GUARANTY SECTION 1.01. GUARANTY OF OBLIGATIONS. Guarantor hereby irrevocably and unconditionally guarantees to Bank and its successors and assigns the due and punctual payment of the Obligations (hereinafter defined). Guarantor hereby irrevocably and unconditionally covenants and agrees that it is liable for the Obligations as primary obligor. SECTION 1.02. DEFINITION OF OBLIGATIONS. As used herein, the term "OBLIGATIONS" means: 1 (a) All indebtedness, liabilities, obligations and duties evidenced by the Note (as such term is defined in the Loan Agreement), whether or not Borrower has any recourse liability therefor to Bank and whether or not the Notes are enforceable against Borrower; (b) Any and all other indebtedness, liabilities, obligations and duties of every kind and character of Borrower to Bank arising pursuant to or related to the Loan Agreement, the Notes, or any loan agreement, security agreement, collateral document or other document, instrument or contract executed in connection with the Loan Agreement whether now or hereafter existing or arising, regardless of whether such present or future indebtedness, liabilities, obligations or duties be direct or indirect, primary or secondary, joint, several, or joint and several, fixed or contingent, and regardless of whether such present or future indebtedness, liabilities, obligations or duties may, prior to their acquisition by Bank, be or have been payable to, or be or have been in favor of, some other person or have been acquired by Bank in any transaction with one other than Borrower including further, without limitation, the "Obligations" as defined in the Loan Agreement; (c) Any and all renewals, extensions, modifications and increases of such indebtedness, liabilities, obligations and duties, or any part thereof, described in items (A) and (B) of this SECTION 1.02; and (d) All costs, expenses and fees, including but not limited to court costs and attorneys' fees, arising in connection with the collection of any or all amounts, indebtedness, obligations and liabilities of Borrower to Bank described in items (A) through (C) of this SECTION 1.02 including costs, expenses and fees arising in connection with the enforcement of this Guaranty. SECTION 1.03. OBLIGATIONS NOT REDUCED BY OFFSET. The Obligations, and the liabilities and obligations of Guarantor to Bank hereunder, shall not be reduced, discharged or released because or by reason of any existing or future offset, claim or defense of Borrower, or any other party, against Bank or against payment of the Obligations, whether such offset, claim or defense arises in connection with the Obligations (or the transactions creating the Obligations) or otherwise. Without limiting the foregoing or the Guarantor's liability hereunder, to the extent that Bank advances funds or extends credit to Borrower, and does not receive payments or benefits thereon in the amounts and at the times required or provided by applicable agreements or laws, Guarantor is absolutely liable to make such payments to (and confer such benefits on) Bank, on a timely basis. SECTION 1.04. "BORROWER" TO INCLUDE SUCCESSORS. The term "Borrower" as used herein shall include any new or successor entity formed as a result of any merger or reorganization of Borrower, and all other successors and assigns of Borrower. SECTION 1.05. PAYMENT BY GUARANTOR. The Guarantor shall have the same rights as Borrower under the Loan Agreement to cure any Event of Default (as defined in the Loan Agreement) within the time periods, and otherwise in accordance with the terms, provided in the Loan Agreement. If all or any part of the Obligations shall not be punctually paid when due, 2 whether at maturity or earlier by acceleration or otherwise, Guarantor shall, immediately upon demand by Bank, and without presentment, protest, notice of protest, notice of non-payment, notice of intention to accelerate or acceleration or any other notice whatsoever, pay in lawful money of the United States of America, the amount due on the Obligations to Bank at Bank's principal office in Dallas, Texas. Such demand(s) may be made at any time coincident with or after the time for payment of all or part of the Obligations, and may be made from time to time with respect to the same or different items of Obligations. Such demand shall be deemed made, given and received in accordance with SECTION 5.02 hereof. SECTION 1.06. NO DUTY TO PURSUE OTHERS.

Until the Obligations shall be paid and satisfied in full, and in cash as to monetary Obligations, and Guarantor shall have performed all of its obligations hereunder, Guarantor shall not receive or collect, directly or indirectly, from Borrower or any other party any amount upon the Guarantor Claims. SECTION 4.02. WAIVER OF SUBROGATION. Unless and until the Obligations have been paid in full and subject to SECTION 4.07, Guarantor hereby waives and releases, to the fullest extent permitted by law: 7 (a) Any and all rights that would result in Guarantor being deemed a "creditor", under the United States Bankruptcy Code, of Borrower or any other person, on account of payments made or obligations performed by Guarantor relating to this Guaranty; and (b) Any claim, right or remedy which Guarantor may now have or hereafter acquire against Borrower that arises hereunder and/or from the performance by any Guarantor hereunder including, without limitation, any claim, remedy or right of subrogation, reimbursement, exoneration, contribution, indemnification, or participation in any claim, right or remedy of Bank against Borrower or any security which now has or hereafter acquires, whether or not such claim, right or remedy arises in equity under contract, by statute, under common law or otherwise.

Guarantor hereby assigns such dividends and payments to Bank. SECTION 4.04. PAYMENTS HELD IN TRUST. In the event that, notwithstanding SECTIONS 4.01, 4.02 and 4.03 above, Guarantor should receive any funds, payment, claim or distribution which is prohibited by such Sections, Guarantor agrees to hold in trust for Bank an amount equal to the amount of all funds, payments, claims or distributions so received, and agrees that it shall have absolutely no dominion over the amount of such funds, payments, claims or distributions, except to pay them promptly to Bank, and Guarantor covenants promptly to pay the same to Bank. SECTION 4.05. LIENS SUBORDINATE. Guarantor agrees that any liens, security interests, judgment liens, charges or other encumbrances upon Borrower's assets securing payment of the Guarantor Claims shall be and remain inferior and subordinate to any liens, security interests, judgment liens, charges or other encumbrances upon Borrower's assets securing payment of the Obligations, regardless of whether such encumbrances in favor of Guarantor or Bank presently exist or are hereafter created or attached. Without the prior written consent of Bank, Guarantor shall not (a) exercise or enforce any creditor's right it may have against Borrower, or (b) foreclose, repossess, sequester or otherwise take steps or institute any action or proceedings (judicial or otherwise, including without limitation the commencement of, or joinder in, any liquidation, bankruptcy, rearrangement, debtor's relief or insolvency proceeding) to enforce any liens, mortgages, deeds of trust, security interest, collateral rights, judgments or other encumbrances on assets of Borrower held by Guarantor.

ARTICLE V MISCELLANEOUS SECTION 5.01. WAIVER. No failure to exercise, and no delay in exercising, on the part of Bank, any right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right. The rights of Bank hereunder shall be in addition to all other rights provided by law. No modification or waiver of any provision of this Guaranty, nor consent to departure therefrom, shall be effective unless in writing and signed by Bank and no such consent or waiver shall extend beyond the particular case and purpose involved. No notice or demand given in any case shall constitute a waiver of the right to take other action in the same, similar or other instances without such notice or demand. SECTION 5.02. NOTICES. Any notices or other communications required or permitted to be given by this Guaranty must be given in writing and in the manner and at the addresses set forth in the Loan Agreement, or at such other address as Guarantor or the Bank shall so designate in writing. SECTION 5.03. USURY COMPLIANCE. It is the intention of Borrower, Guarantor and Bank to conform strictly to applicable usury laws. Accordingly, no agreements, conditions, provisions or stipulations contained in this Guaranty or any other instrument, document or agreement between Guarantor or Borrower and Bank or default of Guarantor or Borrower, or the exercise by Bank of the right to accelerate the payment of the maturity of principal and interest, or to exercise any option whatsoever contained in this Guaranty or any other agreement between Guarantor or Borrower and Bank, or the arising of any contingency whatsoever, shall entitle Bank to collect, in any event, interest exceeding the maximum rate of interest permitted by applicable state or federal law in effect from time to time hereafter (the "MAXIMUM LEGAL RATE") and in no event shall Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and all agreements, conditions or stipulations, if any, which may in any event or contingency whatsoever operate to bind, obligate or compel Guarantor to pay a rate of interest exceeding the Maximum Legal Rate, shall be without binding force or effect, at law or in equity, to the extent only of the excess of interest over such Maximum Legal Rate. In the event any interest is charged in excess of the Maximum Legal Rate ("EXCESS"), Guarantor acknowledges and stipulates that any such charge shall be the result of an accident and bona fide error, and such Excess shall be, first, applied to 9 reduce the principal then unpaid hereunder; second, applied to reduce the Obligations; and third, returned to Guarantor, it being the intention of the parties hereto not to enter at any time into a usurious or otherwise illegal relationship. Guarantor recognizes that, with fluctuations in the applicable rate on the Obligations and the Maximum Legal Rate, such an unintentional result could inadvertently occur. By the execution of this Guaranty, Guarantor covenants that the credit or return of any Excess shall constitute the acceptance by Guarantor of such Excess. SECTION 5.04. CHOICE OF LAW; FORUM SELECTION. This Agreement and the other Loan Documents are being executed and delivered, and are intended to be performed in the State of Texas. Except to the extent that the laws of the United States may apply to the terms of this Agreement or any other Loan Document, the substantive laws of the State of Texas shall govern the validity, construction, enforcement and interpretation of this Guaranty. In the event of a dispute involving this Guaranty, Guarantor irrevocably agrees that venue for such dispute shall lie in any court of competent jurisdiction in Dallas County, Texas. SECTION 5.05. INVALID PROVISIONS. In the case any one or more of the provisions contained in this Guaranty should be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained therein shall not in any way be affected thereby, unless such continued effectiveness of this Guaranty, as modified, would be contrary to the basic understandings and intentions of the parties as expressed herein. SECTION 5.06. PARTIES BOUND. This Guaranty shall be binding upon and inure to the benefit of the parties hereto and their respective successors, assigns and legal representatives; PROVIDED, HOWEVER, that Guarantor may not, without the prior written consent of Bank, assign any of its rights, powers, duties or obligations hereunder. SECTION 5.07. HEADINGS. Section headings are for convenience of reference only and shall in no way affect the interpretation of this Guaranty. SECTION 5.08. MULTIPLE COUNTERPARTS. This Guaranty may be executed in multiple counterparts, all of which taken together shall constitute one and the same agreement, and any of the parties hereto may execute this Guaranty by signing any counterpart. SECTION 5.09. RIGHTS AND REMEDIES. If Guarantor becomes liable for any indebtedness owing by Borrower to Bank, by endorsement or otherwise, other than under this Guaranty, such liability shall not be in any manner impaired or affected hereby and the rights of Bank hereunder shall be cumulative of any and all other rights that Bank may ever have against Guarantor. The exercise by Bank of any right or remedy hereunder or under any other instrument, or at law or in equity, shall not preclude the concurrent or subsequent exercise of any other right or remedy. SECTION 5.10. INDEMNITY. GUARANTOR HEREBY AGREES TO INDEMNIFY, HOLD HARMLESS, AND DEFEND BANK AND ITS DIRECTORS, OFFICERS, AGENTS, COUNSEL AND EMPLOYEES ("INDEMNIFIED PERSONS") FROM AND AGAINST ANY AND ALL LOSSES, LIABILITIES, DAMAGES, COSTS, EXPENSES, SUITS, ACTIONS AND PROCEEDINGS ("LOSSES") EVER SUFFERED 10 OR INCURRED BY ANY INDEMNIFIED PERSON ARISING OUT OF OR RELATING TO THIS GUARANTY, ANY OTHER LOAN DOCUMENT OR ANY OTHER TRANSACTION CONTEMPLATED HEREBY AND THEREBY, INCLUDING, WITHOUT LIMITATION, ANY LOSSES CAUSED BY THE NEGLIGENCE OF SUCH INDEMNIFIED PERSON, BUT NOT INCLUDING ANY LOSSES CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNIFIED PERSON, AND GUARANTOR SHALL REIMBURSE BANK AND EACH OTHER INDEMNIFIED PERSON FOR ANY EXPENSES (INCLUDING IN CONNECTION WITH THE INVESTIGATION OF, PREPARATION FOR OR DEFENSE OF ANY ACTUAL OR THREATENED CLAIM, ACTION OR PROCEEDING ARISING HEREFROM AND THEREFROM, INCLUDING ANY SUCH COSTS OF RESPONDING TO DISCOVERY REQUESTS OR SUBPOENAS, REGARDLESS OF WHETHER BANK OR SUCH OTHER INDEMNIFIED PERSON IS A PARTY THERETO). WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, THIS INDEMNITY SHALL EXTEND TO ANY CLAIMS ASSERTED AGAINST BANK OR ANY OTHER INDEMNIFIED PERSON BY ANY PERSON OR ENTITY UNDER ANY ENVIRONMENTAL LAWS OR SIMILAR LAWS BY REASON OF THE BORROWER'S, GUARANTOR'S OR ANY OTHER PERSON'S OR ENTITY'S FAILURE TO COMPLY WITH LAWS APPLICABLE TO SOLID OR HAZARDOUS WASTE MATERIALS OR OTHER TOXIC SUBSTANCES. EACH INDEMNIFIED PERSON MAY SELECT ITS OWN COUNSEL WITH RESPECT TO ANY LOSSES, IN ADDITION TO THE GUARANTOR'S COUNSEL, AND SHALL BE INDEMNIFIED THEREFOR HEREUNDER. NOTWITHSTANDING ANY CONTRARY PROVISION OF THIS GUARANTY, THE OBLIGATION OF THE COMPANY UNDER THIS SECTION 5.10 SHALL SURVIVE THE PAYMENT IN FULL OF THE COMPANY'S OBLIGATIONS UNDER THE LOAN AGREEMENT AND THE TERMINATION OF THE LOAN AGREEMENT AND THIS GUARANTY. SECTION 5.11. NOTICE OF FINAL AGREEMENT. THIS GUARANTY CONSTITUTES A WRITTEN AGREEMENT WHICH REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES. SUCH WRITTEN AGREEMENT MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.
