(i) Each Grantor shall notify Agent promptly if it knows or has reason to know that any application or registration relating to any Patent, Trademark or Copyright (now or hereafter existing) may become abandoned, cancelled, or declared invalid, or if any such Copyright or Trademark or the invention disclosed in any such Patent is dedicated to the public domain, or of any adverse determination or development in any proceeding in the United States Patent and Trademark Office, the United States Copyright Office, in analogous offices or agencies in other countries or in any court regarding any Grantor’s ownership of any Copyright, Patent, or Trademark, its right to register the same, or to keep and maintain the same.

(ii) If any Grantor, either itself or through any agent, employee, licensee or designee, applies for a Patent or files an application for the registration of any Trademark or Copyright with the United States Patent and Trademark Office, United States Copyright Office or any analogous office or agency in any other country or any political subdivision thereof or otherwise obtains rights in any Patent, Trademark or Copyright, such Grantor will promptly inform Agent, and, upon request of Agent, execute and deliver any and all agreements, instruments, documents, and papers as Agent may reasonably request to evidence Agent’s security interest in such Copyright, Patent or Trademark and the General Intangibles, including, without limitation, in the case of Trademarks, the goodwill of the Grantors, relating thereto or represented thereby; provided that no Grantor shall have any such duty where a Grantor’s Copyright, Patent or Trademark rights in its application would be jeopardized by such action, including, but not limited to, the assignment of an “intent-to-use” Trademark application filed under 15 U.S.C. § 1051(b).

(iii) Each Grantor, consistent with the reasonable conduct and protection of its business, will take all reasonable actions to prosecute vigorously each application and to attempt to obtain the broadest Patent or registration of a Trademark or Copyright therefrom and to maintain each Patent, Trademark registration, and Copyright registration which is material to the conduct of any Grantor’s business, including, without limitation, with respect to Patents, payments of required maintenance fees, and, with respect to Trademarks, filing of applications for renewal, affidavits of use, and affidavits of incontestability. In the event that any Grantor fails to take any of such actions, Agent may do so in any Grantor’s name or in Agent’s name and all reasonable expenses incurred by Agent in connection therewith shall be paid by the applicable Grantor.

(iv) Each Grantor shall use its reasonable efforts to detect infringers of the Copyrights, Patents, and Trademarks which are material to the conduct of any Grantor’s business. In the event that any of the Copyrights, Patents, or Trademarks is infringed, misappropriated, or diluted by a third party, any Grantor shall notify Agent promptly after it learns thereof and shall, if such Copyrights, Patents, or Trademarks are material to the conduct of any Grantor’s business, promptly take appropriate action to protect such Copyrights, Patents, or Trademarks. In the event that any Grantor fails to take any such actions, Agent may do so in any Grantor’s name or Agent’s name and all reasonable expenses incurred by Agent in connection therewith shall be paid by any Grantor.

12

(e) Indemnification. In any suit, proceeding or action brought by Agent or any Lender relating to any Collateral for any sum owing with respect thereto or to enforce any rights or claims with respect thereto, each Grantor will save, defend, indemnify, and keep Agent and Lenders harmless from and against all expense (including reasonable attorneys’ fees and expenses), loss or damage suffered by reason of any defense, setoff, counterclaim, recoupment, or reduction of liability whatsoever of the Account Debtor or other Person obligated on the Collateral, arising out of a breach by any Grantor of any obligation thereunder or arising out of any other agreement, indebtedness, or liability at any time owing to, or in favor of, such obligor or its successors from any Grantor, INCLUDING, WITHOUT LIMITATION, ANY LOSS, EXPENSE OR DAMAGE ARISING IN WHOLE OR IN PART BASED ON THE NEGLIGENCE OR STRICT LIABILITY OF AGENT OR ANY LENDER, except in the case of Agent or any Lender, to the extent such expense, loss, or damage is attributable to the gross negligence, bad faith or willful misconduct (as determined by a court of competent jurisdiction in a final and non-appealable judgment) of Agent or such Lender as finally determined by a court of competent jurisdiction. All such obligations of each Grantor shall be and remain enforceable against and only against Grantors and shall not be enforceable against Agent or any Lender.

(f) Compliance with Terms of Accounts, etc. In all material respects, each Grantor will perform and comply with all obligations in respect of the Collateral and all other agreements to which it is a party or by which it is bound relating to the Collateral.

(g) Limitation on Liens on Collateral. Grantor will not create, permit, or suffer to exist, and each Grantor will defend the Collateral against, and take such other action as is necessary to remove, any Lien on the Collateral except Liens in favor of Agent or otherwise permitted pursuant to the Credit Agreement, and will defend the right, title, and interest of Agent and Lenders in and to any of each Grantor’s rights under the Collateral against the claims and demands of all Persons whomsoever.

(h) Limitations on Disposition. Grantor will not sell, license, lease, transfer, or otherwise dispose of any of the Collateral, or attempt or contract to do so except as permitted by the Credit Agreement.

(i) Further Identification of Collateral. Each Grantor will, if so requested by Agent, furnish to Agent, as often as Agent requests, statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as Agent may reasonably request, all in such detail as Agent may specify.

(j) Notices. Each Grantor will advise Agent promptly, in reasonable detail, (i) of any Lien or claim made or asserted against any of the Collateral, and (ii) of the occurrence of any other event which would have a material adverse effect on the aggregate value of the Collateral or on the Liens created hereunder or under any Other Document.

13

(k) Good Standing Certificates. Each Grantor shall, upon request of Agent, provide to Agent a certificate of good standing (or other analogous certificate) from its jurisdiction of organization.

(l) No Reincorporation. Without limiting any prohibitions on mergers involving any Grantor contained in the Credit Agreement, no Grantor shall reorganize or reincorporate itself under the laws of any jurisdiction other than the jurisdiction in which it is organized as of the date hereof without the prior written consent of Agent.

(m) Terminations; Amendments Not Authorized. Each Grantor acknowledges that it is not authorized to file any financing statement or amendment or termination statement with respect to any financing statement without the prior written consent of Agent and agrees that it will not do so without the prior written consent of Agent, subject to each Grantor’s rights under Section 9-509(d)(2) of the UCC.

(n) Limitations on Each Grantor. Grantor shall not, directly or indirectly, (i) enter into or permit to exist any transaction or other agreement (including any agreement for the incurrence of Indebtedness, any purchase, sale, lease, or exchange of any property or the rendering of any service), between itself and any other Person, unless any of the foregoing are expressly permitted pursuant to the Credit Agreement or the Other Documents or consented to in writing by Agent, (ii) engage in any business or conduct any activity (including the making of any investment or payment or transfer any of its assets, other than the performance of ministerial activities and payment of taxes and administrative fees in connection with or incidental to its ownership of the Equity Interests of the Borrowers) that is prohibited under the terms of the Credit Agreement or (iii) consolidate or merge with or into any other Person (other than to the extent permitted by the Credit Agreement). Grantor shall have no direct Subsidiaries other than those in existence as of the date hereof or to the extent permitted by the Credit Agreement.

6. AGENT’S APPOINTMENT AS ATTORNEY-IN-FACT.

On the Closing Date, each Grantor shall execute and deliver to Agent a power of attorney (the “Power of Attorney”) substantially in the form attached hereto as Exhibit A. The power of attorney granted pursuant to the Power of Attorney is a power coupled with an interest and shall be irrevocable until all of the Obligations of each Borrower under the Credit Agreement have been indefeasibly paid in full, in cash and the Credit Agreement shall have terminated. The powers conferred on Agent, for the benefit of Agent and the Lenders, under the Power of Attorney are solely to protect Agent’s interests in the Collateral and shall not impose any duty upon Agent or any Lender to exercise any such powers. Agent agrees that (a) except for the powers granted in clause (h) of the Power of Attorney, it shall not exercise any power or authority granted under the Power of Attorney unless an Event of Default has occurred and is continuing, and (b) Agent shall account for any moneys received by any third party in respect of any foreclosure on or disposition of any Collateral pursuant to the Power of Attorney provided that neither Agent nor any Lender shall have any duty as to any Collateral, and Agent and Lenders shall be accountable only for amounts that they actually receive as a result of the exercise of such powers. NONE OF AGENT, LENDERS, OR ANY OF THEIR RESPECTIVE AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR REPRESENTATIVES SHALL BE RESPONSIBLE TO ANY GRANTOR FOR ANY ACT OR FAILURE TO ACT UNDER ANY POWER OF ATTORNEY OR OTHERWISE, EXCEPT IN RESPECT OF

14

DAMAGES TO THE EXTENT ATTRIBUTABLE TO THEIR OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT (AS DETERMINED BY A COURT OF COMPETENT JURISDICTION IN A FINAL AND NON-APPEALABLE JUDGMENT), NOR FOR ANY PUNITIVE, EXEMPLARY, INDIRECT, OR CONSEQUENTIAL DAMAGES.

7. REMEDIES: RIGHTS UPON DEFAULT.

(a) In addition to all other rights and remedies granted to it under this Security Agreement, the Credit Agreement, the Other Documents and under any other instrument or agreement securing, evidencing, or relating to any of the Obligations, if any Event of Default shall have occurred and be continuing, Agent may exercise all rights and remedies of a secured party under the UCC. Without limiting the generality of the foregoing, each Grantor expressly agrees that in any such event Agent, without demand of performance or other demand, advertisement, or notice of any kind (except the notice specified below of time and place of public or private sale) to or upon any Grantor or any other Person (all and each of which demands, advertisements, and notices are hereby expressly waived to the maximum extent permitted by the UCC and other Applicable Law), may forthwith enter upon the premises of any Grantor where any Collateral is located through self-help, without judicial process, without first obtaining a final judgment or giving any Grantor or any other Person notice and opportunity for a hearing on Agent’s claim or action and may collect, receive, assemble, process, appropriate, and realize upon the Collateral, or any part thereof, and may forthwith sell, lease, license, assign, give an option or options to purchase, or sell or otherwise dispose of and deliver said Collateral (or contract to do so), or any part thereof, in one or more parcels at a public or private sale or sales, at any exchange at such prices as it may deem acceptable, for cash or on credit or for future delivery without assumption of any credit risk. Agent or any Lender shall have the right upon any such public sale or sales and, to the extent permitted by law, upon any such private sale or sales, to purchase for the benefit of Agent or such Lenders, the whole or any part of said Collateral so sold, free of any right, or equity of redemption, which equity of redemption each Grantor hereby releases. Such sales may be adjourned and continued from time to time with or without notice. Agent shall have the right to conduct such sales on each Grantor’s premises or elsewhere and shall have the right to use each Grantor’s premises without charge for such time or times as Agent deems necessary or advisable.

If any Event of Default shall have occurred and be continuing, each Grantor further agrees, at Agent’s request, to assemble the Collateral and make it available to Agent at a place or places designated by Agent which are reasonably convenient to Agent and such Grantor, whether at such Grantor’s premises or elsewhere. Until Agent is able to effect a sale, lease, or other disposition of the Collateral, Agent shall have the right to hold or use the Collateral, or any part thereof, to the extent that it deems appropriate for the purpose of preserving the Collateral or its value or for any other purpose deemed appropriate by Agent. Agent shall have no obligation to any Grantor to maintain or preserve the rights of any Grantor as against third parties with respect to the Collateral while the Collateral is in the possession of Agent. Agent may, if it so elects, seek the appointment of a receiver or keeper to take possession of the Collateral and to enforce any of Agent’s remedies (for the benefit of Agent and the Lenders) with respect to such appointment without prior notice or hearing as to such appointment. Agent shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization, or sale to the Obligations as provided in the Credit Agreement, and only after so paying over such net proceeds, and after the payment by Agent of any other amount required by any provision of law,

15

need Agent account for the surplus, if any, to any Grantor. To the maximum extent permitted by Applicable Law, any Grantor waives all claims, damages, settlements, and demands against Agent arising out of the repossession, retention, or sale of the Collateral (INCLUDING, WITHOUT LIMITATION, ALL CLAIMS, DAMAGES, SETTLEMENTS, AND DEMANDS ARISING IN WHOLE OR IN PART BASED ON THE NEGLIGENCE OR STRICT LIABILITY OF AGENT OR ANY LENDER) except such as to the extent arise out of the gross negligence, bad faith or willful misconduct (as determined by a court of competent jurisdiction in a final and non-appealable judgment) of Agent or such Lender as finally determined by a court of competent jurisdiction. any Grantor agrees that ten (10) days prior notice by Agent of the time and place of any public sale or of the time after which a private sale may take place is reasonable notification of such matters. any Grantor shall remain liable for any deficiency if the proceeds of any sale or disposition of the Collateral are insufficient to pay all Obligations, including any attorneys’ fees and other expenses incurred by Agent or any Lender to collect such deficiency.

(b) Except as otherwise specifically provided herein, any Grantor hereby waives presentment, demand, protest or any notice (to the maximum extent permitted by Applicable Law) of any kind (including, without limitation, notice of intent to accelerate and notice of acceleration) in connection with this Security Agreement or any Collateral.

(c) To the extent that Applicable Law imposes duties on Agent to exercise remedies in a commercially reasonable manner, any Grantor acknowledges and agrees that it is not commercially unreasonable for Agent (i) to fail to incur expenses reasonably deemed significant by Agent to prepare the Collateral for disposition or otherwise to complete raw material or work in process into finished goods or other finished products for disposition, (ii) to fail to obtain third party consents for access to the Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of the Collateral to be collected or disposed of, (iii) to fail to exercise collection remedies against Account Debtors or other persons obligated on the Collateral or to remove Liens on or any adverse claims against the Collateral, (iv) to exercise collection remedies against Account Debtors and other persons obligated on the Collateral directly or through the use of collection agencies and other collection specialists, (v) to advertise dispositions of the Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, (vi) to contact other Persons, whether or not in the same business as any Grantor, for expressions of interest in acquiring all or any portion of such Collateral, (vii) to hire one or more professional auctioneers to assist in the disposition of the Collateral, whether or not the Collateral is of a specialized nature, (viii) to dispose of the Collateral by utilizing internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capacity of doing so, or that match buyers and sellers of assets, (ix) to dispose of assets in wholesale rather than retail markets, (x) to disclaim disposition warranties, such as title, possession, or quiet enjoyment, (xi) to purchase insurance or credit enhancements to insure Agent against risks of loss, collection or disposition of the Collateral or to provide to Agent a guaranteed return from the collection or disposition of the Collateral, or (xii) to the extent deemed appropriate by Agent, to obtain the services of other brokers, investment bankers, consultants and other professionals to assist Agent in the collection or disposition of any of the Collateral. any Grantor acknowledges that the purpose of this Section 7(c) is to provide non-exhaustive indications of what actions or omissions by Agent would not be commercially

16

unreasonable in Agent’s exercise of remedies against the Collateral and that other actions or omissions by Agent shall not be deemed commercially unreasonable solely on account of not being indicated in this Section 7(c). Without limitation upon the foregoing, nothing contained in this Section 7(c) shall be construed to grant any rights to any Grantor or to impose any duties on Agent that would not have been granted or imposed by this Security Agreement or by Applicable Law in the absence of this Section 7(c).

(d) Neither Agent nor any Lender shall be required to make any demand upon, or pursue or exhaust any of its rights or remedies against, any Grantor, any other obligor, guarantor, pledgor, or any other Person with respect to the payment of the Obligations or to pursue or exhaust any of its rights or remedies with respect to any Collateral therefor or any direct or indirect guarantee thereof. Neither Agent nor any Lender shall be required to marshal the Collateral or any guarantee of the Obligations or to resort to the Collateral or any such guarantee in any particular order, and all of its rights hereunder or under any Other Documents shall be cumulative. To the extent it may lawfully do so, each Grantor absolutely and irrevocably waives and relinquishes the benefit and advantage of, and covenants not to assert against Agent or any Lender, any valuation, stay, appraisement, extension, redemption, or similar laws and any and all rights or defenses it may have as a surety now or hereafter existing (including, without limitation, all rights under Chapter 34 of the Texas Business and Commerce Code) which, but for this provision, might be applicable to the sale of any Collateral made under the judgment, order, or decree of any court, or privately under the power of sale conferred by this Security Agreement, or otherwise.

8. GRANT OF LICENSE TO USE INTELLECTUAL PROPERTY COLLATERAL. For the sole purpose of enabling Agent to exercise rights and remedies under Section 7 hereof (including, without limiting the terms of Section 7 hereof, in order to take possession of, hold, preserve, process, assemble, prepare for sale, market for sale, sell, or otherwise dispose of Collateral) at such time as Agent shall be lawfully entitled to exercise such rights and remedies, each Grantor hereby grants to Agent, for the benefit of Agent and the Lenders, an irrevocable, non-exclusive license (exercisable without payment of royalty or other compensation to any Grantor) to use, license, or sublicense any Copyright, Patent, or Trademark, now owned or hereafter acquired by any Grantor, and wherever the same may be located, and including, without limitation, in such license reasonable access to all media in which any of the licensed items may be recorded or stored and to all computer and automatic machinery software and programs used for the compilation or printout thereof.

9. LIMITATION ON AGENT’S AND LENDERS’ DUTY IN RESPECT OF COLLATERAL. Agent and each Lender shall use reasonable care with respect to the Collateral in its possession or under its control. Neither Agent nor any Lender shall have any other duty as to any Collateral in its possession or control or in the possession or control of any agent or nominee of Agent or such Lender, or any income thereon or as to the preservation of rights against prior parties or any other rights pertaining thereto.

10. REINSTATEMENT. This Security Agreement shall remain in full force and effect and continue to be effective should any petition be filed by or against any Grantor for liquidation or reorganization, should any Grantor become insolvent or make an assignment for the benefit of any creditor or creditors or should a receiver or trustee be appointed for all or any

17

significant part of any Grantor’s assets, and shall continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Obligations, or any part thereof, is, pursuant to Applicable Law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee of the Obligations, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored, or returned, the Obligations shall be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored, or returned.

11. NOTICES. All notices, requests, and demands hereunder shall be in writing and deemed to have been given or made: if delivered in person, immediately upon delivery; if by telex, telegram, or facsimile transmission, immediately upon sending and upon confirmation of receipt; if by nationally recognized overnight courier service with instructions to deliver the next Business Day, one (1) Business Day after sending; and if by certified mail, return receipt requested, five (5) days after mailing. All notices, requests and demands upon the parties are to be given to the following addresses (or to such other address as any party may designate by notice in accordance with this Section):

18

12. SEVERABILITY. Whenever possible, each provision of this Security Agreement shall be interpreted in a manner as to be effective and valid under Applicable Law, but if any provision of this Security Agreement shall be prohibited by or invalid under Applicable Law, such provision shall be ineffective only to the extent of such prohibition or invalidity without invalidating the remainder of such provision or any remaining provisions of this Security Agreement. This Security Agreement is to be read, construed, and applied together with the Credit Agreement and the Other Documents which, taken together, set forth the complete understanding and agreement of Agent, the Lenders and each Grantor with respect to the matters referred to herein and therein.

13. NO WAIVER; CUMULATIVE REMEDIES. Neither Agent nor any Lender shall by any act, delay, omission, or otherwise be deemed to have waived any of its rights or remedies hereunder, and no waiver shall be valid unless in writing, signed by Agent and then only to the extent therein set forth. A waiver by Agent of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which Agent would otherwise have had on any future occasion. No failure to exercise nor any delay in exercising on the part of Agent or any Lender, any right, power or privilege hereunder, shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power, or privilege hereunder preclude any other or future exercise thereof or the exercise of any other right, power, or privilege. The rights and remedies hereunder provided are cumulative and may be exercised singly or concurrently, and are not exclusive of any rights and remedies provided by law. None of the terms or provisions of this Security Agreement may be waived, altered, modified, or amended except by an instrument in writing, duly executed by Agent and each Grantor.

14. LIMITATION BY LAW. All rights, remedies, and powers provided in this Security Agreement may be exercised only to the extent that the exercise thereof does not violate any applicable provision of law, and all the provisions of this Security Agreement are intended to be subject to all applicable mandatory provisions of law that may be controlling and to be limited to the extent necessary so that they shall not render this Security Agreement invalid, unenforceable, in whole or in part, or not entitled to be recorded, registered or filed under the provisions of any Applicable Law.

15. TERMINATION OF THIS SECURITY AGREEMENT. Subject to Section 10 hereof, this Security Agreement shall terminate upon the indefeasible payment in full, in cash, of all Obligations of Borrower (other than contingent indemnification obligations to the extent no unsatisfied claim giving rise there has been asserted) under the Credit Agreement and the termination of the Credit Agreement.

19

16. SUCCESSORS AND ASSIGNS. This Security Agreement and all obligations of each Grantor hereunder shall be binding upon the successors and assigns of each Grantor (including any debtor-in-possession on behalf of any Grantor) and shall, together with the rights and remedies of Agent, for the benefit of Agent and the Lenders, hereunder, inure to the benefit of Agent and the Lenders, all future holders of any instrument evidencing any of the Obligations and their respective successors and assigns. No sales of participations, other sales, assignments, transfers, or other dispositions of any agreement governing or instrument evidencing the Obligations or any portion thereof or interest therein shall in any manner impair the Lien granted to Agent, for the benefit of Agent and the Lenders, hereunder. Grantor may not assign, sell, hypothecate, or otherwise transfer any interest in or obligation under this Security Agreement.

17. COUNTERPARTS. This Security Agreement may be executed in any number of counterparts, each of which when executed and delivered shall be deemed to be an original, and all of which when taken together shall constitute one and the same Agreement.

18. CHOICE OF LAW. THE VALIDITY, INTERPRETATION, AND ENFORCEMENT OF THIS SECURITY AGREEMENT AND THE OTHER DOCUMENTS (OTHER THAN THE MORTGAGES TO THE EXTENT PROVIDED THEREIN) AND ANY DISPUTE ARISING OUT OF THE RELATIONSHIP BETWEEN THE PARTIES HERETO, WHETHER IN CONTRACT, TORT, EQUITY, OR OTHERWISE, SHALL BE GOVERNED BY THE INTERNAL LAWS OF THE STATE OF TEXAS BUT EXCLUDING ANY PRINCIPLES OF CONFLICTS OF LAW OR OTHER RULE OF LAW THAT WOULD CAUSE THE APPLICATION OF THE LAW OF ANY JURISDICTION OTHER THAN THE LAWS OF THE STATE OF TEXAS. GRANTOR, AGENT, AND THE LENDERS IRREVOCABLY CONSENT AND SUBMIT TO THE NON-EXCLUSIVE JURISDICTION OF THE STATE OF TEXAS AND THE UNITED STATES DISTRICT COURTS LOCATED IN THE STATE OF TEXAS, WHICHEVER AGENT MAY ELECT, AND WAIVE ANY OBJECTION BASED ON VENUE OR FORUM NON CONVENIENS WITH RESPECT TO ANY ACTION INSTITUTED THEREIN ARISING UNDER THIS SECURITY AGREEMENT OR ANY OF THE OTHER DOCUMENTS OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS SECURITY AGREEMENT OR ANY OF THE OTHER DOCUMENTS OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY, OR OTHERWISE, AND AGREE THAT ANY DISPUTE WITH RESPECT TO ANY SUCH MATTERS SHALL BE HEARD ONLY IN THE COURTS DESCRIBED ABOVE (EXCEPT THAT AGENT AND THE LENDERS SHALL HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST GRANTOR OR ITS PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION WHICH AGENT DEEMS NECESSARY OR APPROPRIATE IN ORDER TO REALIZE ON THE COLLATERAL OR TO OTHERWISE ENFORCE ITS RIGHTS AGAINST GRANTOR OR ITS PROPERTY).

19. WAIVER OF JURY TRIAL. EACH GRANTOR, AGENT AND THE LENDERS EACH HEREBY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY

20

CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (i) ARISING UNDER THIS SECURITY AGREEMENT OR ANY OF THE OTHER DOCUMENTS OR (ii) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS SECURITY AGREEMENT OR ANY OF THE OTHER DOCUMENTS OR THE TRANSACTIONS RELATED HERETO OR THERETO IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY, OR OTHERWISE. EACH GRANTOR, AGENT, AND THE LENDERS EACH HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT EACH GRANTOR, AGENT, OR ANY LENDER MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS SECURITY AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

20. SECTION TITLES. The Section titles contained in this Security Agreement are and shall be without substantive meaning or content of any kind whatsoever and are not a part of the agreement between the parties hereto.

21. NO STRICT CONSTRUCTION. The parties hereto have participated jointly in the negotiation and drafting of this Security Agreement. In the event an ambiguity or question of intent or interpretation arises, this Security Agreement shall be construed as if drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Security Agreement.

22. USE AND PROTECTION OF COPYRIGHT, PATENT, AND TRADEMARK COLLATERAL. Notwithstanding anything to the contrary contained herein, unless an Event of Default has occurred and is continuing, Agent shall from time to time execute and deliver, upon the written request of the applicable Grantor, any and all instruments, certificates,, or other documents, in the form so requested, necessary or appropriate in the judgment of a Grantor to permit such Grantor to continue to exploit, license, use, enjoy and protect its Copyrights, Patents and Trademarks.

23. GRANTORS’ WAIVER OF RIGHTS UNDER TEXAS DECEPTIVE TRADE PRACTICES ACT. EACH GRANTOR HEREBY WAIVES ANY RIGHTS UNDER THE DECEPTIVE TRADE PRACTICES-CONSUMER PROTECTION ACT, SECTION § 17.41 ET SEQ. TEXAS BUSINESS & COMMERCE CODE, A LAW THAT GIVES CONSUMERS SPECIAL RIGHTS AND PROTECTIONS.

EACH GRANTOR EXPRESSLY WARRANTS AND REPRESENTS THAT GRANTOR (A) IS NOT IN A SIGNIFICANTLY DISPARATE BARGAINING POSITION RELATIVE TO AGENT, AND (B) HAS BEEN REPRESENTED BY LEGAL COUNSEL IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

24. NO ADVISORY OR FIDUCIARY RELATIONSHIP. In connection with all aspects of each transaction contemplated hereby (including in connection with any amendment, waiver or other modification hereof or of any Other Document), any Grantor acknowledges and
