(a) The Secured Party agrees that unless an Event of Default shall have occurred and be continuing, the Pledgor may, to the extent the Pledgor has such right as a holder of the Pledged Shares, vote and give consents, ratifications and waivers with respect thereto, except to the extent that, in the Secured Party’s judgment, any such vote, consent, ratification or waiver could detract from the value thereof as Collateral or which could be inconsistent with or result in any violation of any provision of the Note or this Agreement, and from time to time, upon request from the Pledgor, the Secured Party shall deliver to the Pledgor suitable proxies so that the Pledgor may cast such votes, consents, ratifications and waivers.

(b) All cash dividends and distributions with respect to the Pledged Shares shall be held by the Pledgor and may not be distributed until the Maturity Date and repayment of any outstanding Secured Obligations.

7. Further Assurances.

(a) The Pledgor shall, at its own cost and expense, defend title to the Collateral and the first priority lien and security interest of the Secured Party therein against the claim of any person claiming against or through the Pledgor and shall maintain and preserve such perfected first priority security interest for so long as this Agreement shall remain in effect.

(b) The Pledgor agrees that at any time and from time to time, at the expense of the Pledgor, the Pledgor will promptly execute and deliver all further instruments and documents, obtain such agreements from third parties, and take all further action, that may be necessary or desirable, or that the Secured Party may reasonably request, in order to create and/or maintain the validity, perfection or priority of and protect any security interest granted or purported to be granted hereby or to enable the Secured Party to exercise and enforce its rights and remedies hereunder or under any other agreement with respect to any Collateral.

8. Transfers and Other Liens. The Pledgor agrees that it will not sell, offer to sell, dispose of, convey, assign, donate or otherwise transfer, grant any option with respect to, restrict, or grant, create, permit or suffer to exist any mortgage, pledge, lien, security interest, option, right of first offer, encumbrance or other restriction or limitation of any nature whatsoever on, any of the Collateral or any interest therein except as expressly provided for herein or with the prior written consent of the Secured Party.

9. Secured Party Appointed Attorney-in-Fact. The Pledgor hereby appoints the Secured Party the Pledgor’s attorney-in-fact, with full authority in the place and stead of the Pledgor and in the name of the Pledgor or otherwise, from time to time following any Event of Default, in the Secured Party’s sole discretion to take any action and to execute any instrument which the Secured Party may deem necessary or advisable to accomplish the purposes of this Agreement, including, without limitation, to receive, endorse and collect all instruments made payable to the Pledgor representing any dividend, interest payment or other distribution in respect of the Collateral or any part thereof and to give full discharge for the same (but the Secured Party shall not be obligated to and shall have no liability to the Pledgor or any third party for failure to do so or take action). Such appointment, being coupled with an interest, shall be irrevocable. The Pledgor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof.

10. Secured Party May Perform. If the Pledgor fails to perform any obligation contained in this Agreement, or if any representation or warranty on the part of the Pledgor contained herein shall be breached, the Secured Party may itself perform, or cause performance of, such obligation, or remedy such breach, and the expenses of the Secured Party incurred in connection therewith shall be payable by the Pledgor; provided that the Secured Party shall not be required to perform or discharge any obligation of the Pledgor. Neither the provisions of this Section 10 nor any action taken by the Secured Party pursuant to the provisions of this Section 10 shall prevent any such failure to observe any covenant contained in this Agreement or any breach of representation or warranty from constituting an Event of Default.

11. Reasonable Care. The Secured Party shall have no duty with respect to the care and preservation of the Collateral beyond the exercise of reasonable care. The Secured Party shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which the Secured Party accords its own property, it being understood that the Secured Party shall not have any responsibility for (a) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not the Secured Party has or is deemed to have knowledge of such matters, or (b) taking any necessary steps to preserve rights against any parties with respect to any Collateral. Nothing set forth in this Agreement, nor the exercise by the Secured Party of any of the rights and remedies hereunder, shall relieve the Pledgor from the performance of any obligation on the Pledgor’s part to be performed or observed in respect of any of the Collateral.

12. Remedies Upon Default.

(a) If any Event of Default shall have occurred and be continuing, the Secured Party may, without any other notice to or demand upon the Pledgor, assert all rights and remedies of a secured party under the UCC or other applicable law, including, without limitation, the right to take possession of, hold, collect, sell, lease, deliver, grant options to purchase or otherwise retain, liquidate or dispose of all or any portion of the Collateral. If notice prior to disposition of the Collateral or any portion thereof is necessary under applicable law, written notice mailed or delivered to the Pledgor at its notice address as provided in the Note ten (10) days prior to the date of such disposition shall constitute reasonable notice, but notice given in any other reasonable manner shall be sufficient. So long as the sale of the Collateral is made in a commercially reasonable manner, the Secured Party may sell such Collateral on such terms and to such purchaser(s) as the Secured Party in its absolute discretion may choose, without assuming any credit risk and without any obligation to advertise or give notice of any kind other than that necessary under applicable law. Without precluding any other methods of sale, the sale of the Collateral or any portion thereof shall have been made in a commercially reasonable manner if conducted in conformity with reasonable commercial practices of creditors disposing of similar property. At any sale of the Collateral, if permitted by applicable law, the Secured Party may be the purchaser, licensee, assignee or recipient of the Collateral or any part thereof and shall be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any portion of the Collateral sold, assigned or licensed at such sale, to use and apply any of the Secured Obligations as a credit on account of the purchase price of the Collateral or any part thereof payable at such sale. To the extent permitted by applicable law, the Pledgor waives all claims, damages and demands it may acquire against the Secured Party arising out of the exercise by it of any rights hereunder. The Pledgor hereby waives and releases to the fullest extent permitted by law any right or equity of redemption with respect to the Collateral, whether before or after sale hereunder, and all rights, if any, of marshalling the Collateral and any other security for the Secured Obligations or otherwise. At any such sale, unless prohibited by applicable law, the Secured Party or any custodian may bid for and purchase all or any part of the Collateral so sold free from any such right or equity of redemption. Neither the Secured Party nor any custodian shall be liable for failure to collect or realize upon any or all of the Collateral or for any delay in so doing, nor shall it be under any obligation to take any action whatsoever with regard thereto.

(b) If any Event of Default shall have occurred and be continuing, all rights, if any, of the Pledgor to (i) exercise the voting and other consensual rights it would otherwise be entitled to exercise pursuant to Section 6(a) and (ii) receive the dividends and other distributions which it would otherwise be entitled to receive and retain pursuant to Section 6(b), shall immediately cease, and all such rights shall thereupon become vested in the Secured Party, which shall have the sole right to exercise such voting and other consensual rights and receive and hold such dividends and other distributions as Collateral.

(c) If any Event of Default shall have occurred and be continuing, any cash held by the Secured Party as Collateral and all cash Proceeds received by the Secured Party in respect of any sale of, collection from, or other realization upon all or any part of the Collateral shall be applied in whole or in part by the Secured Party to the payment of expenses incurred by the Secured Party in connection with the foregoing or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Secured Party hereunder, including reasonable attorneys’ fees, and the balance of such proceeds shall be applied or set off against all or any part of the Secured Obligations in such order as the Secured Party shall elect. Any surplus of such cash or cash Proceeds held by the Secured Party and remaining after payment in full of all the Secured Obligations shall be paid over to the Pledgor or to whomsoever may be lawfully entitled to receive such surplus. The Pledgor shall remain liable for any deficiency if such cash and the cash Proceeds of any sale or other realization of the Collateral are insufficient to pay the Secured Obligations and the fees and other charges of any attorneys employed by the Secured Party to collect such deficiency.

(d) If the Secured Party shall determine to exercise its rights to sell all or any of the Collateral pursuant to this Section, the Pledgor agrees that, upon request of the Secured Party, the Pledgor will, at its own expense, do or cause to be done all such acts and things as may be necessary to make such sale of the Collateral or any part thereof valid and binding and in compliance with applicable law.

13. No Waiver and Cumulative Remedies. The Secured Party shall not by any act (except by a written instrument pursuant to Section 20), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Event of Default. All rights and remedies herein provided are cumulative and are not exclusive of any rights or remedies set forth in any other Loan Documents or provided by law.

14. SECURITY INTEREST ABSOLUTE. The Pledgor hereby waives demand, notice, protest, notice of acceptance of this Agreement, notice of loans made, credit extended, Collateral received or delivered, or other action taken in reliance hereon and all other demands and notices of any description. All rights of the Secured Party and liens and security interests hereunder, and all Secured Obligations of the Pledgor hereunder, shall be absolute and unconditional irrespective of:

(a) any illegality or lack of validity or enforceability of any Secured Obligation or any related agreement or instrument;

(b) any change in the time, place or manner of payment of, or in any other term of, the Secured Obligations, or any rescission, waiver, amendment or other modification of the Note, this Agreement or any Loan Documents, including any increase in the Secured Obligations resulting from any extension of additional credit or otherwise;

(c) any taking, exchange, substitution, release, impairment or non-perfection of any Collateral or any other collateral, or any taking, release, impairment, amendment, waiver or other modification of any guaranty, for all or any of the Secured Obligations;

(d) any manner of sale, disposition or application of proceeds of any Collateral or any other collateral or other assets to all or part of the Secured Obligations;

(e) any default, failure or delay, willful or otherwise, in the performance of the Secured Obligations;

(f) any defense, set-off or counterclaim (other than a defense of payment or performance) that may at any time be available to, or be asserted by, the Pledgor against the Secured Party; or

(g) any other circumstance (including, without limitation, any statute of limitations) or manner of administering the Loan or any existence of or reliance on any representation by the Secured Party that might vary the risk of the Pledgor or otherwise operate as a defense available to, or a legal or equitable discharge of, the Pledgor or any other grantor, guarantor or surety.

15. Addresses For Notices. All notices and other communications provided for in this Agreement shall be in writing and shall be given in the manner and become effective as set forth in the Note, and addressed to the respective parties at their addresses as specified in the Note or as to either party at such other address as shall be designated by such party in a written notice to each other party in accordance with the Note.

16. Continuing Security Interest; Further Actions. This Agreement shall create a continuing first priority lien and security interest in the Collateral and shall, subject to Section 17, remain in full force and effect until payment and performance in full of the Secured Obligations.

17. Termination; Release. On the date on which the Loan and other Secured Obligations have been paid and performed in full, the Secured Party will, at the request and sole expense of the Pledgor, (a) duly assign, transfer and deliver to or at the direction of the Pledgor (without recourse and without any representation or warranty) such of the Collateral as may then remain in the possession of the Secured Party, and (b) execute and deliver to the Pledgor a proper instrument or instruments acknowledging the satisfaction and termination of this Agreement.

18. Governing Law; Venue; Jurisdiction. This Agreement and the other Loan Documents are governed by and construed in accordance with the substantive laws of the state of Delaware, excluding its conflicts of law provisions. Any dispute arising under, in connection with, or incident to this Agreement or the other Loan Documents or about the interpretation thereof will be resolved exclusively in the state or federal courts located in Tarrant County, Texas. Pledgor irrevocably submits to those courts’ venue and jurisdiction. Pledgor waives all defenses of lack of personal jurisdiction and forum non-conveniens. A final judgment in any such suit or action may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable law.

19. Waiver of Jury Trial. PLEDGOR HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY RELATING TO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY WHETHER BASED ON CONTRACT, TORT, OR ANY OTHER THEORY.

20. Modification. None of the terms or provisions of this Agreement may be excluded, waived, modified or amended except by a written instrument duly executed on behalf of Pledgor and Secured Party expressly referring to this Agreement and setting forth the provision so excluded, waived, modified, or amended.

21. Severability. In the event any one or more of the provisions contained in the Loan Documents should be held to be invalid, illegal or unenforceable in any respect, the validity, enforceability and legality of the remaining provisions contained in the Loan Documents shall not in any manner be affected thereby and shall be enforceable in accordance with their terms.

22. Legal Fees and Expenses. Pledgor shall be obligated to the Secured Party (a) to pay Secured Party all reasonable fees, expenses and costs (including reasonable attorneys’ fees and expenses) incurred by the Secured Party in connection with any amendments, restatements, replacements, substitutions or modifications of any of the Loan Documents executed or delivered thereafter, and (b) to pay Secured Party for all reasonable out-of-pocket expenses and costs (including reasonable attorneys’ fees and court costs) related to the administration, collection, and enforcement of the Loan Documents.

23. Successors and Assigns. This Agreement and the other Loan Documents shall be binding upon Pledgor and Secured Party and will inure to the benefit of Pledgor and Secured Party and their respective successors and permitted assigns, except that Pledgor may not assign or transfer any of its rights or obligations under this Note or the other Loan Documents without the prior written consent of Secured Party. Secured Party may, at any time, assign any of its rights or obligations under this Agreement or the other Loan Documents without the consent of Pledgor.

24. Construction. Unless the express context otherwise requires: (a) the words “hereof”, “herein”, and “hereunder” and words of similar import, when used in this Agreement, shall refer to this Agreement as a whole and not to any particular provision of this Agreement; (b) the terms defined in the singular have a comparable meaning when used in the plural, and vice versa; (c) the terms “Dollars” and “$” mean United States Dollars; (d) wherever the word “include,” “includes,” or “including” is used in this Agreement, it shall be deemed to be followed by the words “without limitation”; (e) the word “or” shall be disjunctive but not exclusive, and (f) references to the “parties” means Secured Party and Pledgor. The parties agree that they have been represented by counsel during the negotiation and execution of this Agreement and, therefore, waive the application of any applicable law or rule of construction providing that ambiguities in an agreement or other document will be construed against the party or parties drafting such agreement or document. Unless expressly provided otherwise, any approval or consent required to be given by a party in this Agreement shall be given or withheld by such party in its sole discretion.

25. Multiple Counterparts and Facsimile Signatures. This Agreement and any amendments, waivers, consents or supplements hereto may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all taken together shall constitute a single contract. Delivery of an executed counterpart of a signature page to this Agreement by facsimile or in electronic (i.e., “pdf” or “tif”) format shall be effective as delivery of a manually executed counterpart of this Agreement.

26. Time of Essence. Time is of the essence for each and every provision of this Agreement.
