6.1 The Pledgor covenants and agrees that it will defend the Lender’s lien and security interest in and to the Pledged Stock against the claims and demands of all Persons.

6.2 The Pledgor covenants and agrees that without the prior written consent of the Lender, it will not sell, convey or otherwise dispose of any of the Pledged Stock, or create, incur or permit to exist any pledge, lien, mortgage, hypothecation, security interest, charge, option or any other encumbrance or restriction with respect to any of the Pledged Stock, or any interest therein, or any proceeds thereof, except for the liens and security interests created by this Pledge Agreement.

ARTICLE VII

RIGHTS AND REMEDIES UPON DEFAULT

7.1 If any Default under the Loan Agreement or a default or breach in any respect by the Pledgor of any representation, warranty, covenant or agreement of the Pledgor under this Pledge Agreement (after the expiration of any applicable cure period or grace period hereunder or thereunder, which breach shall be deemed a Default under the Loan Agreement and a Default hereunder) shall occur, the Lender may do any one or more of the following: (a) declare the Obligations Secured Hereby to be forthwith due and payable, whereupon such Obligations Secured Hereby shall become immediately due and payable without presentment, demand, protest or other notice of any kind; and/or (b) proceed to protect and enforce its rights under this Pledge Agreement, the Notes, the Loan Agreement, or any of the other Loan Documents through other appropriate proceedings, and the Lender shall have, without limitation, all of the rights and remedies provided by applicable law, including, without limitation, the rights and remedies of a secured party under the Texas Uniform Commercial Code (the “UCC”) and, in addition thereto, the Lender shall be entitled, at the Lender’s option, to exercise all voting and corporate rights with respect to the Pledged Stock as it may determine, without liability therefor, but the Lender shall not have any duty to exercise any voting and corporate rights in respect of the Pledged Stock and shall not be responsible or liable to the Pledgor or any other Person for any failure to do so or delay in so doing.

7.2 Without limiting the generality of the foregoing, if any Default under the Loan Agreement shall occur, and Lender has accelerated the payment of any indebtedness under the Loan Agreement, the Lender shall have the right to sell the Pledged Stock, or any part thereof, at public or private sale or at any broker’s board or on any securities exchange for cash, upon credit or for future delivery, and at such price or prices as the Lender may deem best, and the Lender may be the purchaser of any or all of the Pledged Stock so sold and thereafter the Lender or any other purchaser shall hold the same free from any right or claim of whatsoever kind. The Lender is authorized, at any such sale, if it deems it advisable so to do, to restrict the number of prospective bidders or purchasers to Persons who will represent and agree that they are purchasing for their own account, for investment, and not with a view to the distribution or resale of the Pledged Stock and may otherwise require that such sale be conducted subject to restrictions as to such other matters as the Lender may deem necessary in order that such sale may be effected in such manner as to comply with all applicable state and federal securities laws. Upon any such sale, the Lender shall have the right to deliver, assign and transfer to the purchaser thereof the Pledged Stock so sold.

7.3 Each purchaser at any such sale shall hold the property sold, absolutely free from any claim or right of whatsoever kind, including any equity or right of redemption of’ the Pledgor, who hereby specifically waives all rights of redemption, stay or appraisal which it has or may have under any rule of law or statute now existing or hereafter adopted. The Lender shall

6

give the Pledgor not less than ten days’ written notice of its intention to make any such public or private sale or at any broker’s board or on any securities exchange (with such notice to state the time and place of such sale), and the Pledgor agrees that such notice shall be deemed reasonable.

7.4 Any such public sale shall be held at such time or times within the ordinary business hours and at such place or places as the Lender may fix in the notice of such sale. At any sale, the Pledged Stock may be sold in one lot as an entirety or in parts, as the Lender may determine. The Lender shall not be obligated to make any sale pursuant to any such notice. The Lender may, without notice or publication, adjourn any sale, and such sale may be made at any time or place to which the same may be so adjourned. In case of any sale of all or any part of the Pledged Stock on credit or for future delivery, the Pledged Stock so sold may be retained by the Lender until the selling price is paid by the purchaser thereof, but the Lender shall not incur any liability in case of the failure of such purchaser to take up and pay for the Pledged Stock so sold and, in case of any such failure, such Pledged Stock may again be sold upon like notice.

7.5 The Lender, instead of exercising the power of sale herein conferred upon it, may proceed by a suit or suits at law or in equity to foreclose this Pledge Agreement and sell the Pledged Stock, or any portion thereof, under a judgment or decree of a court or courts of competent jurisdiction.

7.6 On any sale of the Pledged Stock, the Lender is hereby authorized to comply with any limitation or restriction in connection with such sale that it may be advised by counsel is necessary in order to avoid any violation of applicable law or in order to obtain any required approval of the purchaser or purchasers by any third party or any governmental regulatory authority or officer or court, including, without limitation, all limitations and restrictions imposed by federal and state banking laws and regulations. Compliance with the foregoing sentence shall result in such sale or disposition being considered or deemed to have been made in a commercially reasonable manner.

7.7 In furtherance of the exercise by the Lender of the rights and remedies granted to it hereunder, the Pledgor agrees that, upon request of the Lender and at the expense of the Pledgor, it will use its Best Efforts to obtain all third party and governmental approvals necessary for or incidental to the exercise of remedies by the Lender with respect to the Pledged Stock or any part thereof, including, without limitation, approvals from the FRB and the FDIC. .

ARTICLE VIII

PRIVATE SALES

8.1 The Pledgor hereby acknowledges that, notwithstanding that a higher price might be obtained for the Pledged Stock at a public sale than at a private sale or sales, the making of a public sale of the Pledged Stock may be subject to registration requirements and other legal restrictions compliance with which could require such actions on the part of the Pledgor, could entail such expenses and could subject the Lender and any underwriter through whom the Pledged Stock may be sold and any controlling Person of any thereof to such liabilities as would make the making of a public sale of the Pledged Stock impractical. Accordingly, the Pledgor hereby agrees that private sales made by the Lender in accordance with the provisions of Article VII hereof may be at prices and on other terms less favorable to the seller than if the Pledged

7

Stock were sold at public sale, that the Lender shall not have any obligation to take any steps in order to permit the Pledged Stock to be sold at a public sale complying with the requirements of federal and state securities and similar laws, and that such sale shall not be deemed to be made in a commercially unreasonable manner solely because of its nature as a private sale.

8.2 The Pledgor further agrees to use its Best Efforts to do or cause to be done all such other acts as may be necessary to make any sale or sales of all or any portion of the Pledged Stock pursuant to Article VII and this Article VIII valid and binding and in compliance with any and all other applicable requirements of law. The Pledgor further agrees that a breach of any of the covenants contained in Article VII and this Article VIII will cause irreparable injury to the Lender, that the Lender has no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in Article VII and this Article VIII shall be specifically enforceable against the Pledgor, and the Pledgor hereby waives and agrees, to the extent permitted by law, not to assert any defenses to the granting of equitable relief (such as, without limitation, any defense that the Lender has an adequate remedy at law or that the Lender will not be irreparably injured) in any action for specific performance of such covenants.

ARTICLE IX

LIMITATION ON DUTIES REGARDING PLEDGED STOCK

The Lender’s sole duty with respect to the custody, safekeeping and physical preservation of the Pledged Stock in its possession, under Section 9-207 of the UCC or otherwise, shall be to deal with it in the same manner as the Lender deals with similar securities and property for its own account. Neither the Lender nor any of its directors, officers, employees or agents shall be liable for any good faith failure to demand, collect or realize upon any of the Pledged Stock or for any delay in doing so or shall be under any obligation to see or otherwise dispose of any Pledged Stock or for any good faith delay in doing so or shall be under any obligation to see or otherwise dispose of any Pledged Stock upon the request of the Pledgor or otherwise.

10.4 No Waiver; Cumulative Remedies.
