2. At Will Employment. The Company agrees to employ Executive, and Executive agrees to serve the Company, on an “at will” basis, which means that either the Company or Executive may terminate Executive’s employment with the Company at any time and for any or no reason, as provided in and subject to Sections 7 and 8 below.

3. Compensation. During Executive’s employment, the Company shall pay to Executive the following compensation:

(a) Base Salary. The Company shall pay Executive a base salary (“Base Salary”) at the rate of $15,833.33 per month (annualized to $190,000), less applicable withholding taxes, payable in accordance with the Company’s normal payroll practices. The Base Salary may be increased by the Board of Directors, or a duly authorized committee thereof, in its sole discretion. In addition, the Board of Directors, or a duly authorized committee thereof, may decrease the Base Salary in the event that the Board or such committee determines that financial exigencies require such decrease, provided that the compensation of all executives of the Company is also reduced at the same time in a substantially commensurate manner. Any increase or decrease in Base Salary (together with the then existing Base Salary) shall serve as the “Base Salary” for future employment under this Agreement.

(b) Equity Compensation. Executive may be granted stock options, stock appreciation rights, restricted stock units, restricted stock or other stock- or performance-based equity awards (each, an “Award”), as determined from time to time in the discretion of the Company’s Board of Directors or a duly authorized committee thereof, under the Company’s Amended and Restated 2005 Stock Plan or any other equity incentive plan that may be adopted by the Company’s Board of Directors (each, an “Equity Plan”).

5. Business Expenses. The Company shall reimburse Executive for all reasonable and necessary business and travel expenses incurred by Executive in the performance of Executive’s duties under this Agreement. The determination of “reasonable and necessary” shall be made in the sole discretion of the Board. Such expenses shall be reimbursed in accordance with the Company’s business expense guidelines, limits and procedures and upon presentation of proper expense vouchers or receipts; provided however, in no event shall reimbursement of an eligible expense hereunder be made later than the last day of Executive’s taxable year following the taxable year in which the expense was incurred and the right to reimbursement hereunder may not be exchanged for any other benefit.

(ii) accelerated vesting with respect to all Awards under an Equity Plan held by Executive, such that all Awards under an Equity Plan that would vest based solely on the passage of time (rather than vesting based on performance conditions) and that would vest within the six (6) month period following the date of such termination shall vest effective as of the date of termination, except and only to the extent that any Award Agreement specifically provides otherwise;

(iii) continuing severance pay at a rate equal to 100% of Executive’s Base Salary, as then in effect (less applicable withholding taxes), for a period of six (6) months from the date of such termination, to be paid periodically in accordance with the Company’s normal payroll practices (subject to Sections 7(c) and 7(d));

(ii) accelerated vesting with respect to all Awards under an Equity Plan held by Executive, such that all Awards under an Equity Plan that would vest based solely on the passage of time (rather than vesting based on performance conditions) and that would vest within the twelve (12) month period following the date of termination shall vest effective as of the date of such termination, except and only to the extent that any Award Agreement specifically provides otherwise, provided, that if a particular Award Agreement has a definition of “Change of Control” or “Change in Control” that differs from the definition of “Change of Control” set forth in this Agreement, such other definition shall apply solely with respect to acceleration of vesting of such Award pursuant to this Section 7(b)(ii);

(c) Section 409A. Notwithstanding anything to the contrary in this Agreement, no severance pay or benefits to be paid or provided to Executive, if any, pursuant to this Agreement that, when considered together with any other severance payments or separation benefits, are considered deferred compensation under Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and the final regulations and any guidance promulgated thereunder (“Section 409A”) (together, the “Deferred Payments”) will be paid or otherwise provided until Executive has a “separation from service” within the meaning of Section 409A. Similarly, no severance payable to Executive, if any, pursuant to this Agreement that otherwise would be exempt from Section 409A pursuant to Treasury Regulation Section 1.409A-1(b)(9) will be payable until Executive has a “separation from service” within the meaning of Section 409A. If Executive is a “specified employee” within the meaning of Section 409A at the time of Executive’s termination (other than due to death), then the Deferred Payments that are payable within the first six (6) months following Executive’s separation from service will become payable on the first payroll date that occurs on or after the date six (6) months and one (1) day following the date of Executive’s separation from service. All subsequent Deferred Payments, 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 Executive’s separation from service but prior to the six (6) month anniversary of the separation from service, 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 Payments will be payable in accordance with the payment schedule applicable to each payment or benefit. Each payment and benefit payable under this Agreement is intended to constitute a separate payment for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. The foregoing provisions are 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. References in this Agreement to termination of Executive’s employment shall mean termination of Executive’s employment with the Company and all entities required to be aggregated with the Company and treated as one employer under Section 414(b) or (c) of the Code under circumstances that give rise to a “separation from service” within the meaning given to that term under Section 409A.

(d) Conditions Precedent. Any severance payments (other than payment of Base Salary pursuant to Section 7), vesting and/or benefits contemplated by Section 7 above are conditional on Executive (i) continuing to comply with all of the provisions of Section 9 below and the terms of the Confidentiality Agreement (as defined below), and (ii) signing and not revoking a separation agreement and release of claims providing for a release of all claims relating to Executive’s employment and/or this Agreement against the Company or its successor, its subsidiaries and parent company and their respective directors, officers and stockholders, excluding claims for payments and/or benefits the Company is required to pay to Executive that have not been made or delivered in accordance with terms of a written agreement between the Company and Executive or as required by law, in a form satisfactory to the Company, its parent company or its successor (the “Release”); provided that such Release becomes effective and irrevocable no later than sixty (60) days following the termination date or such earlier date required by the Release (such deadline, the “Release Deadline”). If the Release does not become effective by the Release Deadline, Executive will forfeit any rights to severance or

benefits under this Section 7 or elsewhere in this Agreement. Any severance payments or other benefits under this Agreement that would be considered Deferred Payments (as defined in Section 7(c)) will be paid on, or, in the case of installments, will not commence until, the sixtieth (60th) day following Executive’s separation from service, or, if later, such time as required by Section 7(c). Except as required by Section 7(c), any installment payments that would have been made to Executive during the sixty (60) day period immediately following Executive’s separation from service but for the preceding sentence will be paid to Executive on the sixtieth (60th) day following Executive’s separation from service and the remaining payments will be made as provided in this Agreement, unless subject to the 6-month payment delay described herein. Any severance payments under this Agreement that would not be considered Deferred Payments will be paid on, or, in the case of installments, will not commence until, the first payroll date that occurs on or after the date the Release becomes effective and any installment payments that would have been made to Executive during the period prior to the date the Release becomes effective following Executive’s separation from service but for the preceding sentence will be paid to Executive on the first payroll date that occurs on or after the date the Release becomes effective.

Executive further acknowledges the time, geographic and scope limitations of Executive’s obligations under subsection 9(e)(i) above are reasonable, especially in light of the Company’s desire to protect its Confidential Information, and that Executive will not be precluded from gainful employment if Executive is obligated not to compete with the Company during the period and within the Territory as described above.

This Agreement is binding on Executive and on the Company and Executive’s and the Company’s successors and assigns (whether by assignment, by operation of law or otherwise); provided that neither this Agreement nor any rights or obligations hereunder may be assigned by Executive or the Company without the prior written consent of the other party (except that the Company shall be entitled to assign this Agreement in connection with a Change of Control).

(c) Absence of Conflict. Executive represents and warrants that Executive’s employment by the Company as described herein will not conflict with and will not be constrained by any prior employment or consulting agreement or relationship. Executive further agrees that during Executive’s employment with the Company, Executive will not improperly use or disclose any proprietary information or trade secrets of any former or concurrent employer or other person or entity and that Executive will not bring onto the premises of the Company any unpublished document or proprietary information belonging to any such employer, person or entity unless consented to in writing by such employer, person or entity.

(d) Arbitration.

(i) General. In consideration of Executive’s service to the Company, its promise to arbitrate all employment related disputes and Executive’s receipt of the compensation and other benefits paid to Executive by the Company, at present and in the future, Executive agrees that any and all controversies, claims, or disputes (with the sole exception of those disputes that may arise from the Confidentiality Agreement, which shall be resolved in

accordance with the dispute resolution procedures set forth therein) with anyone (including the Company and any employee, officer, director, stockholder or benefit plan of the Company in their capacity as such or otherwise) arising out of, relating to, or resulting from Executive’s service to the Company under this Agreement or otherwise or the termination of Executive’s service with the Company, including any breach of this Agreement, shall be subject to binding arbitration under the Arbitration Rules set forth by the American Arbitration Association for the resolution of employment disputes (the “Rules”) and pursuant to Texas law. Disputes which Executive agrees to arbitrate, and thereby agrees to waive any right to a trial by jury, include any statutory claims under state or federal law. Executive further understands that this Agreement to arbitrate also applies to any disputes that the Company may have with Executive.

(ii) Procedure. Any arbitration will be administered by the American Arbitration Association (“AAA”) and a neutral arbitrator will be selected in a manner consistent with its National Rules for the Resolution of Employment Disputes. The arbitration proceedings will be conducted in Richardson, Texas, and will allow for discovery according to the rules set forth in the National Rules for the Resolution of Employment Disputes. The arbitrator shall have the power to decide any motions brought by any party to the arbitration, including motions for summary judgment and/or adjudication and motions to dismiss and demurrers, prior to any arbitration hearing. The arbitrator shall issue a written decision including findings of fact and conclusions of law on the merits of its award. The arbitrator shall have the power to award any remedies, including attorneys’ fees and costs, available under applicable law. The Company will pay for any administrative or hearing fees charged by the arbitrator or AAA except that Executive shall pay the first $125 of any filing and/or administration fees associated with any arbitration that Executive initiates. The arbitrator shall administer and conduct any arbitration in a manner consistent with the AAA’s National Rules for the Resolution of Employment Disputes.

(iii) Remedy. Arbitration shall be the sole, exclusive and final remedy for any dispute (with the sole exception of those disputes that may arise from the Confidentiality Agreement and Section 9 of this Agreement) between Executive and the Company. Accordingly, except as otherwise provided herein, neither Executive nor the Company will be permitted to pursue court action regarding claims that are subject to arbitration. Notwithstanding, the arbitrator will not have the authority to disregard or refuse to enforce any lawful Company policy, and the arbitrator shall not order or require the Company to adopt a policy not otherwise required by law, which the Company has not adopted.

(iv) Availability of Injunctive Relief. Any party may also petition the court for injunctive relief where either party alleges or claims a violation of this Agreement or the Confidentiality Agreement, including but not limited to a breach of the restrictive covenants in Section 9 above. In the event that either party seeks injunctive relief, no bond shall be required and the prevailing party shall be entitled to recover reasonable costs and attorneys’ fees.

(e) Voluntary Nature of Agreement; Legal Rights. Executive is executing this Agreement voluntarily and without any duress or undue influence by the Company or anyone else. Executive acknowledges that Executive has had the opportunity to consult with an attorney regarding the provisions of this Agreement and has either obtained such advice of counsel or knowingly waived the opportunity to seek such advice. Executive has carefully read this Agreement and has asked any questions needed for Executive to understand the terms, consequences and binding effect of this Agreement and fully understand it, including that Executive is waiving Executive’s right to a jury trial.

(f) Waivers. No party shall be deemed to have waived any right, power or privilege under this Agreement or any provisions hereof unless such waiver shall have been duly executed in writing and acknowledged by the party to be charged with such waiver. The failure of any party at any time to insist on performance of any of the provisions of this Agreement shall in no way be construed to be a waiver of such provisions, nor in any way to affect the validity of this Agreement or any part hereof. No waiver of any breach of this Agreement shall be held to be a waiver of any other subsequent breach.

(g) Reformation. If any sentence, paragraph or clause of this Agreement, or combination of the same, is in violation of any applicable law or regulation, or is unenforceable or void for any reason, such sentence, paragraph, clause or combinations of same shall be modified to the extent necessary to accomplish the intention on such provision without violating applicable law or regulation. Notwithstanding, the remainder of the Agreement shall remain binding upon the parties.

(h) Notices. All notices, approvals, consents, requests or demands required or permitted to be given under this Agreement shall be in writing and shall be deemed sufficiently given on the earlier of (i) actual receipt, (ii) three business days after being deposited in U.S. mail, registered or certified, postage prepaid, (iii) upon delivery, if delivered by hand (iv) one business day after transmission, if sent by facsimile (confirmation received) or (v) one business day after the business day of deposit with a reputable overnight courier for next business day delivery, freight prepaid.

(j) Severability. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable of void, this Agreement shall continue in full force and effect without said provision.

(k) Effect of Headings. The Section and subsection headings contained herein are for convenience only and shall not affect the construction hereof.
