5. Cumulative Rights.

Enforcement by the holder of this Promissory Note of any security for the payment hereof shall not constitute any election by it of remedies so as to preclude the exercise of any other remedy available to it.

6. Waiver. Maker, and each surety, endorser, guarantor and other party ever liable for the payment of any sum of money payable on this Promissory Note, jointly and severally waive demand, presentment, protest, notice of nonpayment, notice of intention to accelerate, notice of protest, notice of acceleration and any and all lack of notice or diligence or any delay in collection or the filing of suit hereon which may occur, and agree that their liability on this Promissory Note shall not be affected by any renewal or extension in the time of payment hereof, by any indulgences, by any release of any party primarily or secondarily liable hereon, or by any release, substitution, subordination or change in any security for the payment of this Promissory Note.

10. GOVERNING LAW. THE LAWS OF THE STATE OF TEXAS SHALL GOVERN THE CONSTRUCTION, VALIDITY, ENFORCEMENT, AND INTERPRETATION HEREOF, EXCEPT TO THE EXTENT FEDERAL LAWS OTHERWISE GOVERN THE VALIDITY, CONSTRUCTION, ENFORCEMENT AND INTERPRETATION HEREOF.

11. Headings; Construction. The headings of the sections of this Promissory Note are inserted for convenience only and shall not be deemed to constitute a part hereof, words used herein of any gender shall be construed to include any other gender where appropriate, and words used herein which are either singular or plural shall be construed to include the other where appropriate.

12. Successors and Assigns. All of the covenants, stipulations, promises and agreements in this Promissory Note contained by or on behalf of Maker shall bind its successors and assigns, whether so expressed or not; provided, however, that Maker may not, without the prior written consent of Payee, assign any rights, duties, or obligations under this Promissory Note.

13. Maximum Interest Rate. It is expressly stipulated and agreed to be the intent of Maker and Payee at all times to comply strictly with the applicable Texas law governing the maximum rate or amount of interest payable on this Promissory Note (or applicable United States federal law to the extent that it permits Payee 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: (i) contracted for, charged, taken, reserved or received pursuant to this Promissory Note, any of the other Loan Documents or any other communication or writing by or between Maker and Payee related to the transaction or transactions that are the subject matter of the Loan Documents; (ii) contracted for, charged or received by reason of Payee’s exercise of the option to accelerate the maturity of this Promissory Note; or (iii) Maker will have paid or Payee will have received by reason of any voluntary prepayment by Maker of this Promissory Note, then it is Maker’s and Payee’s express intent that all amounts charged in excess of the Maximum Lawful Rate shall be automatically cancelled, ab initio, and all amounts in excess of the Maximum Lawful Rate theretofore collected by Payee shall be credited on the principal balance of this Promissory Note (or, if this Promissory Note has been or would thereby be paid in full, refunded to Maker), and the provisions of this Promissory Note and the other Loan Documents 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 this Promissory Note has been paid in full before the end of the stated term of this Promissory Note, then Maker and Payee agree that Payee shall, with reasonable promptness after Payee discovers or is advised by Maker that interest was received in an amount in excess of the Maximum Lawful Rate, either refund such excess interest to Maker and/or credit such excess interest against this Promissory Note then owing by Maker to Payee. Maker hereby agrees that as a condition precedent to any claim seeking usury penalties against Payee, Maker will provide written notice to Payee, advising Payee in reasonable detail of the nature and amount of the violation, and Payee 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 Maker or crediting such excess interest against this Promissory Note then owing by Maker to Payee. All sums contracted for, charged or received by Payee for the use, forbearance or detention of any debt evidenced by this Promissory Note shall, to the extent permitted by applicable law, be amortized or spread, using the actuarial method, throughout the stated term of this Promissory Note (including any and all renewal and extension periods) until payment in full so that the rate or amount of interest on account of this Promissory Note does not exceed the Maximum Lawful Rate from time to time in effect and applicable to this Promissory Note 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 this Promissory Note. Notwithstanding anything to the contrary contained herein or in any of the other Loan Documents, it is not the intention of Payee 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. As used herein, the term “Maximum Lawful Rate” shall mean the maximum lawful rate of interest which may be contracted for, charged, taken, received or reserved by Payee in accordance with the applicable laws of the State of Texas (or applicable United States federal law to the extent that it permits Payee to contract for, charge, take, receive or reserve a greater amount of interest than under Texas law), taking into account all Charges (hereinafter defined) made in connection with the transaction evidenced by this Promissory Note and the other Loan Documents. As used herein, the term “Charges” shall mean all fees, charges and/or any other things of value, if any, contracted for, charged, received, taken or reserved by Payee in connection with the transactions relating to this Promissory Note and the other Loan Documents, which are treated as interest under applicable law. To the extent that Payee is relying on Chapter 303 of the Texas Finance Code to determine the Maximum Lawful Rate payable on this Promissory Note, Payee will utilize the weekly ceiling from time to time in effect as provided in such Chapter 303, as amended. To the extent United States federal law permits Payee to contract for, charge, take, receive or reserve a greater amount of interest than under Texas law, Payee will rely on United States federal law instead of such Chapter 303 for the purpose of determining the Maximum Lawful Rate. Additionally, to the extent permitted by applicable law now or hereafter in effect, Payee may, at its option and from time to time, utilize any other method of establishing the Maximum Lawful Rate under such Chapter 303 or under other applicable law by giving notice, if required, to Maker as provided by applicable law now or hereafter in effect.

14. Payments; Business Day. Each payment or prepayment hereon must be paid at the office of Payee specified above in lawful money as therein specified and in funds which are or will be available for immediate use by Payee at such office on or before 1:00 p.m., Dallas, Texas time, on the day such payment or prepayment is due. In any case where a payment of principal or interest hereof is due on a day which is not a Business Day, Maker, shall be entitled to delay such payment until the next succeeding Business Day, but interest shall continue to accrue until the payment is, in fact, made. As used herein “Business Day” means every day on which banking associations located in Texas are allowed to be open for general lending business.

15. Loan Payable at Maturity.

THE PRINCIPAL INDEBTEDNESS EVIDENCED BY THIS PROMISSORY NOTE IS PAYABLE IN FULL AT MATURITY.
