24.    Construction of Agreement. This Agreement has been negotiated by the respective parties, and the language shall not be construed for or against either party.

25.    Section 409A.

(a)    Notwithstanding anything to the contrary in this Agreement, if (i) Executive is a “specified employee” within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and the final regulations and any guidance promulgated thereunder (“Section 409A”) at the time of Executive’s termination (other than due to death), and (ii) the stock of the Company is publicly traded, then the severance payable to Executive, if any, pursuant to this Agreement, when considered together with any other severance payments or separation benefits which may be considered deferred compensation under Section 409A (together, the “Deferred Compensation Separation Benefits”) will not and could not under any circumstances, regardless of when such termination occurs, be paid in full by March 15 of the year following Executive’s termination, then only that portion of the Deferred Compensation Separation Benefits which do not exceed the Section 409A Limit (as defined below) may be made within the first six (6) months following Executive’s termination of employment in accordance with the payment schedule applicable to each payment or benefit.

For these purposes, each severance payment is hereby designated as a separate payment and will not collectively be treated as a single payment. Any portion of the Deferred Compensation Separation Benefits in excess of the Section 409A Limit shall accrue and, to the extent such portion of the Deferred Compensation Separation Benefits would otherwise have been payable within the first six (6) months following Executive’s termination of employment, will become payable on the first payroll date that occurs on or after the date six (6) months and

9

one (1) day following the date of Executive’s termination. All subsequent Deferred Compensation Separation Benefits, if any, will be payable in accordance with the payment schedule applicable to each payment or benefit. Notwithstanding anything herein to the contrary, if Executive dies following his termination but prior to the six (6) month anniversary of his termination, then any payments delayed in accordance with this paragraph will be payable in a lump sum as soon as administratively practicable after the date of Executive’s death and all other Deferred Compensation Separation Benefits will be payable in accordance with the payment schedule applicable to each payment or benefit.

(b)    The foregoing provision is intended to comply with the requirements of Section 409A so that none of the severance payments and benefits to be provided hereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to so comply. The Company and Executive agree to work together in good faith to consider amendments to this Agreement and to take such reasonable actions which are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to Executive under Section 409A.

(c)    For purposes of this Agreement, “Section 409A Limit” will mean the lesser of two (2) times: (A) Executive’s annualized compensation based upon the annual rate of pay paid to Executive during the Company’s taxable year preceding the Company’s taxable year of Executive’s termination of employment as determined under Treasury Regulation 1.409A-1(b)(9)(iii)(A)(1) and any Internal Revenue Service guidance issued with respect thereto; or (B) the maximum amount that may be taken into account under a qualified plan pursuant to Section 401(a)(17) of the Code for the year in which Executive’s employment is terminated.

(a)    Restrictions on Use and Disclosure. I agree that, during my employment and at all times thereafter, I will hold the Proprietary Information in strict confidence and I will not use, reproduce, disclose or deliver, directly or indirectly, any Proprietary Information except to the extent necessary to perform my duties as an employee of the Company or as permitted by a duly authorized representative of the Company. I will use my best efforts to prevent the unauthorized use, reproduction, disclosure or delivery of Proprietary Information by others.

(b)    Location. I agree to maintain at my work station and/or any other place under my control only such Proprietary Information as I have a current “need to know.” I agree to return to the appropriate person or location or otherwise properly dispose of Proprietary Information once that need to know no longer exists. I agree not to remove Proprietary Information from the Company’s premises except as required in the course of my employment with the Company.

In addition to the restrictions set forth in this Section 2, I will not use, reproduce, disclose or deliver such Proprietary Information except as permitted by the Company’s agreement with such third party.

(d)    Interference with Business. I acknowledge that, because of my responsibilities at the Company, I will help to develop, and will be exposed to, the Company’s business strategies, information on customers and clients, and other valuable Proprietary Information and trade secrets, and that use or disclosure of such Proprietary Information and trade secrets in breach of this Agreement would be extremely difficult to detect or prove. I also

14

acknowledge that the Company’s relationships with its employees, customers, clients, vendors, and other persons are valuable business assets. Therefore, I agree as follows:

(i)    I shall not, during my employment or for a period of one year following termination of my employment with the Company for any reason, directly or indirectly solicit, induce, recruit, or encourage any officer, director, employee, independent contractor or consultant of the Company who was employed by or affiliated with the Company at the time of my termination to leave the Company or terminate his or her employment or relationship with the Company.

(ii)    I shall not, following the termination of my employment with the Company for any reason, use the Company’s Proprietary Information or trade secrets or any other means that would amount to unfair competition to solicit any of the Company’s customers, clients, vendors, business partners, or suppliers, or otherwise interfere with any business relationship or contract between the Company and any of its customers, clients, vendors, business partners, or suppliers.

(iii)    I shall not, for a period of one year following the termination of my employment, solicit any actual or prospective customer or client of the Company for the purpose of selling products or services competitive with the Company’s that I had notice of or worked with during my employment with the Company and that I received trade secret or Proprietary Information about during my employment.

I understand and agree that nothing in this Section 2 limits or modifies in any way my duties under any other Section of this Agreement or any applicable law regarding the Company’s Proprietary Information.

28.    Privacy; Protection of Personal Information.

(a)    Privacy. I acknowledge that the Company may access all information and materials generated, received or maintained by or for me on the premises or equipment of the Company (including, without limitation, computer systems and electronic or voice mail systems), and I hereby waive any privacy rights I may have with respect to such information and materials.

(b)    Protection of Personal Information. During my employment with the Company and thereafter, I shall hold Personal Information in the strictest confidence and shall not disclose or use Personal Information about other individuals, except in connection with my work for the Company, or unless expressly authorized in writing by an authorized representative of the Company. I understand that there are laws in the United States and other countries that protect Personal Information, and that I must not use Personal Information about other individuals other than for the purposes for which it was originally used or make any disclosures of other individuals’ Personal Information to any third party or from one country to another without prior approval of an authorized representative of the Company. I understand that nothing in this Agreement prevents me from discussing my wages or other terms and conditions of my employment with coworkers or others, unless such discussion would be for the purpose of engaging in unfair competition or other unlawful conduct.

(c)    Definition of Personal Information. “Personal Information” means personally identifiable information about employees, independent contractors or third party

15

individuals, including names, addresses, telephone or facsimile numbers, Social Security Numbers, background information, credit card or banking information, health information, or other information entrusted to the Company.

29.    Inventions.

(i)    I understand that the term “Inventions” in this Agreement means any and all ideas, concepts, inventions, discoveries, developments, modifications, improvements, know-how, trade secrets, data, designs, diagrams, plans, specifications, methods, processes, techniques, formulas, algorithms, tools, works of authorship, derivative works, software, content, textual or artistic works, mask works, video, graphics, sound recordings, structures, products, prototypes, systems, applications, creations and technologies in any stage of development, whether or not patentable or reduced to practice and whether or not copyrightable, that relate in any manner to the business of the Company or its affiliates, or the actual or demonstrably anticipated research or development of the Company or its affiliates.

(ii)    I understand that the term “Intellectual Property Rights” in this Agreement means any and all (A) patents, utility models, industrial rights and similar intellectual property rights registered or applied for in the United States and all other countries throughout the world (including all reissues, divisions, continuations, continuations-in-part, renewals, extensions and reexaminations thereof); (B) rights in trademarks, service marks, trade dress, logos, domain names, rights of publicity, trade names and corporate names (whether or not registered) in the United States and all other countries throughout the world, including all registrations and applications for registration of the foregoing and all goodwill related thereto; (C) copyrights (whether or not registered) and rights in works of authorship, databases and mask works, and registrations and applications for registration thereof in the United States and all other countries throughout the world, including all renewals, extensions, reversions or restorations associated with such copyrights, now or hereafter provided by law, regardless of the medium of fixation or means of expression; (D) rights in trade secrets and other confidential information and know-how in the United States and all other countries throughout the world; (E) other intellectual property or proprietary rights in the United States and all other countries throughout the world, including all neighboring rights and sui generis rights; (F) rights to apply for, file, register establish, maintain, extend or renew any of the foregoing; (G) rights to enforce and protect any of the foregoing, including the right to bring legal actions for past, present and future infringement, misappropriation or other violations of any of the foregoing; and (H) rights to transfer and grant licenses and other rights with respect to any of the foregoing, in the Company’s sole discretion and without a duty of accounting.

(b)    Assignment. I hereby assign, and agree to assign automatically upon creation, to the Company, without additional compensation, my entire right, title and interest (including, without limitation, all Intellectual Property Rights) in and to (a) all Inventions that are made, conceived, discovered or developed by me (either alone or jointly with others), or result from or are suggested by any work performed by me (either alone or jointly with others) for or on behalf of the Company or its affiliates, (i) during the period of my employment with the Company, whether before or after the execution of this Agreement and whether or not made,

16

conceived, discovered or developed during regular business hours or (ii) during or after the period of my employment with the Company, whether before or after the execution of this Agreement, if based on or using Proprietary Information or otherwise in connection with my activities as an employee of the Company (collectively, the “Company Inventions”), and (b) all benefits, privileges, causes of action and remedies relating to the Company Inventions, whether before or hereafter accrued (including, without limitation, the exclusive rights to apply for and maintain all registrations, renewals and/or extensions; to sue for all past, present or future infringements or other violations of any rights in the Invention; and to settle and retain proceeds from any such actions), free and clear of all liens and encumbrances. I agree that all such Company Inventions are the sole property of the Company or any other entity designated by it, and all Intellectual Property Rights shall vest in and inure to the benefit of the Company or such other entity. I agree and acknowledge that all copyrightable Company Inventions shall be considered works made for hire prepared within the scope of my employment.

(c)    License. If, under applicable law notwithstanding the foregoing, I retain any right, title or interest (including any Intellectual Property Right) with respect to any Company Invention, I hereby grant and agree to grant to the Company, without any limitations or additional remuneration, a worldwide, exclusive, royalty-free, irrevocable, perpetual, transferable and sublicenseable (through multiple tiers) license to make, have made, use, import, sell, offer to sell, practice any method or process in connection with, copy, distribute, prepare derivative works of, display, perform and otherwise exploit such Company Invention and I agree not to make any claim against the Company or its affiliates, suppliers or customers with respect to such Company Invention.

(d)    Records; Disclosure. I agree to keep and maintain adequate and current written records regarding all Inventions made, conceived, discovered or developed by me (either alone or jointly with others) during my period of employment or after the termination of my employment if based on or using Proprietary Information or otherwise in connection with my activities as an employee of the Company. I agree to make available such records and disclose promptly and fully in writing to the Company all such Inventions, regardless of whether I believe the Invention is a Company Invention subject to this Agreement, and the Company will examine such disclosure in confidence to make such determination. Any such records related to Company Inventions shall be the sole property of the Company.

(e)    Assistance and Cooperation. I agree to cooperate with and assist the Company, and perform, during and after my employment, all acts deemed necessary or desirable by the Company, to apply for, obtain, establish, perfect, maintain, evidence, enforce or otherwise protect any of the full benefits, enjoyment, right, title and interest throughout the world in the Company Inventions. Such acts may include, but are not limited to, execution of assignments of title and other documents and assistance or cooperation in legal proceedings. Should the Company be unable to secure my signature on any such document, whether due to my mental or physical incapacity or any other cause, I hereby irrevocably designate and appoint the Company and each of its duly authorized representatives as my agent and attorney-in-fact, with full power of substitution and delegation, to undertake such acts in my name as if executed and delivered by me (which appointment is coupled with an interest), and I waive and quitclaim to the Company any and all claims of any nature whatsoever that I may have or may later have for infringement of any Intellectual Property Rights in or to the Company Inventions.

17

(f)    Moral Rights. To the extent allowed by applicable law, the assignment of the Company Inventions includes all rights of paternity, integrity, disclosure and withdrawal and any other rights that may be known as or referred to as “moral rights,” “artist’s rights,” “droit moral,” or the like (collectively “Moral Rights”). To the extent I retain any such Moral Rights under applicable law, I hereby waive and agree not to institute, support, maintain or permit any action or proceeding on the basis of, or otherwise assert, such Moral Rights. I hereby authorize the Company to publish the Company Inventions in the Company’s sole discretion with or without attributing any of the foregoing to me or identifying me in connection therewith and regardless of the effect on such Company Inventions or my relationship thereto. I agree to ratify and consent to any action that may be taken or authorized by the Company with respect to such Company Inventions, and I will confirm any such ratifications and consents from time to time as requested by the Company.

(g)    Excluded Inventions. I agree to identify in Schedule A all Inventions, if any, that I wish to exclude from the scope of this Agreement, including all Inventions made, conceived, discovered or developed (either alone or jointly with others) prior to my employment by the Company (collectively, “Excluded Inventions”). I represent and warrant that such list is complete and accurate, and I understand that by not listing an Invention I am acknowledging that such Invention was not made, conceived, discovered or developed prior to my employment by the Company. I agree to notify the Board in writing before I make any disclosure to, or perform any work on behalf of, the Company that appears to conflict with proprietary rights I claim in any Invention listed on Schedule A. If I fail to give such notice, I agree that I will make no claim against the Company with respect to any such Invention.

(h)    Employee Inventions and Third Party Inventions. I shall not, without prior written approval by the Company, make any disclosure to the Company of or incorporate into Company property or Company Inventions any Invention owned by me or in which I have an interest (an “Employee Invention”) or owned by a third party (a “Third Party Invention”). If, in the course of my employment with the Company, I make any disclosure to the Company of or incorporate into Company property or Company Inventions an Employee Invention, with or without Company approval, I hereby grant and agree to grant to the Company a worldwide, nonexclusive, royalty-free, irrevocable, perpetual, transferable and sublicenseable (through multiple tiers) license to make, have made, use, import, sell, offer to sell, practice any method or process in connection with, copy, distribute, prepare derivative works of, display, perform and otherwise exploit such Employee Invention and I agree not to make any claim against the Company or its affiliates, suppliers or customers with respect to any such Employee Invention.

(i)    Representations; Warranties and Covenants. I represent, warrant and covenant that: (i) I have the right to grant the rights and assignments granted herein, without the need for any assignments, releases, consents, approvals, immunities or other rights not yet obtained; (ii) any Company Inventions that are copyrightable works are my original works of authorship; and (iii) neither the Company Inventions nor any element thereof are subject to any restrictions or to any mortgages, liens, pledges, security interests, encumbrances or encroachments.

(j)    Adequate Consideration. I acknowledge that the Company Inventions and the associated Intellectual Property Rights may have substantial economic value, that any and all

18

proceeds resulting from use and exploitation thereof shall belong solely to the Company, and that the salary and other compensation I receive from the Company for my employment with the Company includes fair and adequate consideration for all assignments, licenses and waivers hereunder.

30.    Prohibition on Disclosure or Use of Third Party Confidential Information. I will not disclose to the Company or induce the Company to use any confidential, proprietary or trade secret information or materials belonging to others (including without limitation any former employers) at any time, nor will I use any such information or materials in the course of my employment with the Company. Additionally, I will not bring any confidential, proprietary or trade secret information or material belonging to others onto the Company’s premises. I acknowledge that no officer or other employee or representative of the Company has requested or instructed me to disclose or use any such information or materials, and I will immediately inform my supervisor in the event I believe that my work at the Company would make it difficult for me not to disclose to the Company any such information or materials.

31.    No Conflicts; Former Agreements. I represent and warrant that I have no other agreements or relationships with or commitments to any other person or entity that conflict with my obligations to the Company as an employee of the Company or under this Agreement, and that my employment and my performance of the terms of this Agreement will not require me to violate any obligation to or confidence with another. I agree I will not enter into any oral or written agreement in conflict with this Agreement. Except as disclosed on Schedule A to this Agreement, I represent and warrant that I have not entered into any other agreements or relationships with or commitments to any other person or entity regarding proprietary information or Inventions.

32.    Third Party and Government Contracts. I understand that the Company has or may enter into contracts with other persons or entities, including the United States government or its agents, under which certain Intellectual Property Rights will be required to be protected, assigned, licensed, or otherwise transferred. I hereby agree to be bound by all such agreements, and to execute such other documents and agreements as are necessary to enable the Company to meet its obligations under any such contracts.

33.    Duty of Loyalty. I understand that my employment with the Company requires my full attention and effort. I agree that during the period of my employment by the Company I will not, without the Company’s express written consent, engage in any employment or business activity other than for the Company, including but not limited to employment or business activity which is competitive with, or would otherwise conflict with or distract me from, my employment by the Company. While employed by the Company, I will not undertake any planning for any outside business activity: (i) competitive with the work which I perform with the Company; or (ii) competitive with the profit unit of the Company for which I work.

34.    Termination; Return of Materials. I agree to promptly return all property of the Company, including, without limitation, (a) all source code, books, manuals, records, models, drawings, reports, notes, contracts, lists, blueprints, and other documents or materials and all copies thereof, (b) all equipment furnished to or prepared by me in the course of or incident to my employment, and (c) all written or tangible materials containing Proprietary Information in

19

my possession upon termination of my employment for any reason or at any other time at the Company’s request. Following my termination, I will not retain any written or other tangible material containing any Proprietary Information or information pertaining to any Company Invention. I understand that my obligations contained in this Agreement will survive the termination of my employment and I will continue to make all disclosures required of me by Section 4(c) above. In the event of the termination of my employment, I agree, if requested by the Company, to sign and deliver the Termination Certificate attached as Schedule B hereto. I agree that after the termination of my employment, I will not enter into any agreement that conflicts with my obligations under this Agreement. The termination of any employment or other agreement between the Company and me shall not terminate this Agreement and each and all of the terms and conditions hereof shall survive and remain in full force and effect.

35.    Remedies. I recognize that nothing in this Agreement is intended to limit any remedy of the Company under prevailing law governing the protection of trade secrets or other Intellectual Property Rights. In addition, I acknowledge that any breach by me of this Agreement would cause irreparable injury to the Company for which pecuniary compensation would not afford adequate relief and for which it would be extremely difficult to ascertain the amount of compensation which would afford adequate relief to the Company. Therefore, I agree that if I breach any provision of this Agreement, the Company shall be entitled to injunctive or other equitable relief to remedy any breach or prevent any threatened breach of this Agreement, without the necessity of posting bond or other security or proving it has sustained any actual damage. This remedy will be in addition to any other remedies available to the Company at law or in equity.

36.    Miscellaneous Provisions.

(a)    Assignment; Binding Effect. I acknowledge and agree that my performance is personal hereunder, and that I shall have no right to assign, delegate or otherwise transfer and shall not assign, delegate or otherwise transfer any rights or obligations under this Agreement. Any such assignment, delegation or other transfer shall be null and void. This Agreement may be assigned or transferred by the Company. Subject to the foregoing, this Agreement shall inure to the benefit of the Company and its affiliates, successors and assigns, and shall be binding on me and my heirs, executors, administrators, devisees, spouses, agents, legal representatives and successors in interest.

(b)    Waiver of Limitations. I waive the benefit of any statute of limitations affecting my liability under this Agreement or the enforcement of the Agreement to the full extent permitted by law.

(c)    Governing Law. This Agreement will be governed by and construed in accordance with the laws of the State of Texas, without giving effect to its conflict of law rules.

(d)    Jurisdiction. The parties agree that any legal action or other legal proceeding, including any arbitration, relating to this Agreement or the enforcement of any provision of this Agreement may be brought or otherwise commenced or held in the State of Texas (the “Forum”). Each Party to this Agreement (i) expressly and irrevocably consents and submits to the exclusive jurisdiction of the Forum in connection with any such legal proceeding,

20

(ii) agrees that the Forum shall be deemed to be a convenient forum and the exclusive forum for resolution of any and all disputes relating to this Agreement; (iii) agrees not to assert, by way of motion, as a defense or otherwise, in any such legal proceeding commenced in any state or federal court located in the Forum, any claim that this Agreement is not to be construed or governed by the law of the internal laws of the State of Texas, that such party is not subject personally to the jurisdiction of such court, that such legal proceeding has been brought in an inconvenient forum, that the venue of such proceeding is improper, or that this Agreement or the subject matter of this Agreement may not be enforced in or by such court; and (iv) agrees not to pursue any action arising out of or relating to this Agreement in any forum other than the Forum.

(e)    Severability. If any provision of this Agreement, or application thereof to any person, place, or circumstance, shall be held by a court of competent jurisdiction to be unenforceable, such provision shall be enforced to the greatest extent permitted by law and the remainder of this Agreement shall remain in full force and effect.

(f)    Waivers. Delay or failure to exercise any right or remedy under this Agreement shall not constitute a waiver of such right or remedy. Any waiver of any breach of this Agreement shall not operate as a waiver of any subsequent breaches. All rights or remedies specified for a party herein shall be cumulative and in addition to all other rights and remedies of the party hereunder or under applicable law.

(g)    Counterparts; Facsimile. This Agreement may be executed and delivered by facsimile signature and in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

(h)    Further Assurances. The undersigned shall from time to time and at all times hereafter make, do, execute, or cause or procure to be made, done and executed such further acts, deeds, conveyances, consents and assurances without further consideration, which may reasonably be required to effect the transactions contemplated by this Agreement.

(i)    Attorneys’ Fee. If any arbitration, litigation, or other legal proceeding occurs between the parties relating to this Agreement, the prevailing party shall be entitled to recover (in addition to any other relief awarded or granted) its reasonable costs and expenses (including attorneys’ fees) incurred in the proceeding and any appeal therefrom.

(j)    Interpretation. This Agreement shall be construed as a whole, according to its fair meaning, and not in favor of or against any party. Sections and section headings contained in this Agreement are for reference purposes only, and shall not affect in any manner the meaning of interpretation of this Agreement. Whenever the context requires, references to the singular shall include the plural and the plural the singular and any gender shall include any other gender.

(k)    Entire Agreement; Amendment. This Agreement, including without limitation the Schedules and Exhibits hereto, constitutes the entire agreement between the Company and me with respect to the subject matter hereof and replaces and supersedes any prior or existing agreement entered into by me and the Company with respect to the subject matter hereof. This Agreement may not be modified or amended, in whole or in part, except by a

21

writing signed by me and a duly authorized representative of the Company other than me. I agree that any subsequent change in my duties or compensation for employment will not affect the validity or scope of this Agreement.
