terminate his employment hereunder voluntarily for reasons other than Good Reason (as defined in Section 6.5) at any time upon at least 30 days’ written notice to the Company.

5.3 Termination by the Company Without Cause . The Company may terminate the employment of Executive hereunder without Cause upon at least 30 days’ written notice to Executive. At the time Executive’s employment is terminated by the Company (i.e., at the expiration of such notice period), all remaining obligations of the Company and Executive under Sections 1 through 3 will immediately cease (except as expressly provided below), and the Company will pay Executive, and Executive will be entitled to receive, the following:

6

Payments and benefits under this Section 5.3 are subject to Section 5.6.

5.4 Termination by Executive for Good Reason . Executive may terminate his employment hereunder for Good Reason upon 30 days’ written notice to the Company which notice must be given within 90 days of the Executive’s actual knowledge of the occurrence of the condition that is the basis for such Good Reason; provided, however, that if the basis for such Good Reason is correctible and the Company has corrected the basis for such Good Reason within 30 days after receipt of such notice, Executive may not then terminate his employment for Good Reason with respect to the matters addressed in the written notice. At the time Executive’s employment is terminated by Executive for Good Reason (i.e., at the expiration of such notice period), all obligations of the Company and Executive under Sections 1 through 3 will immediately cease (except as expressly provided below), and the Company will pay Executive, and Executive will be entitled to receive, the same compensation and rights specified in Section 5.3(i) – (vi) and subject to Section 5.6.

5.5 Other Terms Relating to Certain Terminations of Employment . In the event Executive’s employment terminates for any reason set forth in Section 5.1 through 5.4, Executive will be entitled to the benefit of any terms of plans or agreements applicable to Executive which are more favorable than those specified in this Section 5 (except without duplication of payments or benefits, including in the case of any cash bonus payment under Section 3.2 for the year of termination in lieu of which a Partial Year Bonus is paid hereunder). Except as otherwise provided under Section 5.6, amounts payable under this Section 5 following Executive’s termination of employment, other than those expressly payable on a deferred or installment basis, will be paid as promptly as practicable after such a termination of employment. All expenses reimbursable pursuant to Section 3.6 shall be reimbursed by the end of the calendar year after the calendar year in which the expense was incurred.

5.6 Limitations Under Code Section 409A . Anything in this Agreement to the contrary notwithstanding, if (A) on the date of termination of Executive’s employment with the Company or a subsidiary, any of the Company’s stock is publicly traded on an established securities market or otherwise (within the meaning of Section 409A(a)(2)(B)(i) of the Internal Revenue Code, as amended (the “ Code ”)), (B) Executive is determined to be a “specified employee” within the meaning of Section 409A(a)(2)(B) of the Code, (C) the payments exceed the amounts permitted to be paid pursuant to Treasury Regulations section 1.409A-1(b)(9)(iii) and (D) such delay is required to avoid the imposition of the tax set forth in Section 409A(a)(1) of the Code as a result of such termination, the Executive would receive any payment that, absent

7

the application of this Section 5.6, would be subject to interest and additional tax imposed pursuant to Section 409A(a) of the Code as a result of the application of Section 409A(2)(B)(i) of the Code (such additional tax, together with any such interest and penalties, are hereinafter referred to as the “ Additional Tax ”), then no such payment shall be payable prior to the date that is the earliest of (1) 6 months after the Executive’s termination date, (2) the Executive’s death or (3) such other date as will cause such payment not to be subject to such interest and additional tax (with a catch-up payment equal to the sum of all amounts that have been delayed to be made as of the date of the initial payment plus interest equal to the rate provided in Section 1274(b)(2)(B) of the Code).

It is the intention of the parties that payments or benefits payable under this Agreement not be subject to Additional Tax. To the extent such potential payments or benefits could become subject to such Section, the parties shall cooperate to amend this Agreement with the goal of giving the Executive the economic benefits described herein in a manner that does not result in such tax being imposed.

6. Definitions Relating to Termination Events .

6.1 “Cause”. For purposes of this Agreement, “ Cause ” shall mean Executive’s:

No act, or failure to act, on the part of Executive shall be deemed “willful” unless done, or omitted to be done, by Executive not in good faith and without reasonable belief that his action or omission was in the best interest of the Company. Notwithstanding the foregoing, Executive shall not be deemed to have been terminated for Cause unless and until there shall have been delivered to Executive a copy of the resolution duly adopted by the Board finding that, in the good faith opinion of the Board, Executive was found to have engaged in the conduct set forth above.

6.2 “Change in Control”. For purposes of this Agreement, a “ Change in Control ” means the following:

9

6.3 “Compensation Accrued at Termination”. For purposes of this Agreement, “ Compensation Accrued at Termination ” means the following:

6.4 “Disability”. For purposes of this Agreement, “ Disability ” means the Executive is unable due to a physical or mental condition to perform the essential functions of his position with or without reasonable accommodation for six (6) months in the aggregate during any twelve (12) month period or based on the written certification by two licensed physicians of the likely continuation of such condition for such period, one selected by the Company or its insurance carrier and the other selected by the Executive or his legal representative. This definition shall be interpreted and applied consistent with the Americans with Disabilities Act, the Family and Medical Leave Act, Section 409A of the Code and other applicable law.

10

6.5 “Good Reason”. For purposes of this Agreement, “ Good Reason ” shall mean, without Executive’s express written consent, the occurrence of any of the following circumstances unless, if correctable, such circumstances are fully corrected within 30 days of the notice of termination given in respect thereof:

6.6 “Partial Year Bonus”. For purposes of this Agreement, a “ Partial Year Bonus ” is an amount equal to the Executive’s Target Bonus, multiplied by a fraction the numerator of which is the number of days Executive was employed in the year of termination (disregarding any period of Disability during that year) and the denominator of which is the total number of days in the year of termination.

7. Excise Tax-Related Provisions . In the event Executive becomes entitled to any amounts or benefits payable in connection with a Change in Control or other change in control (whether or not such amounts are payable pursuant to this Agreement) (the “ Severance Payments ”), if any of such Severance Payments are subject to the tax (the “ Excise Tax ”) imposed by Section 4999 of the Code (or any similar federal, state or local tax that may hereafter be imposed), the Company shall pay to Executive at the time specified in Section 7(iii) hereof an additional amount (the “ Gross-Up Payment ”) such that the net amount retained by Executive, after deduction of any Excise Tax on the Total Payments (as hereinafter defined) and any federal, state and local income tax and Excise Tax upon the payment provided for by this Section 7, shall

11

be equal to the Total Payments; provided, however that in the event the aggregate value of the Total Payments exceeds three times the Executive’s “base amount,” as defined in Section 280G(b)(3) of the Code, (the “Parachute Threshold”) by an amount equal to less than ten percent (10%) of the Parachute Threshold, one or more of the Total Payments shall be reduced to an aggregate amount that is two hundred ninety-nine percent (299%) of the Executive’s “base amount.” Unless the Executive shall have given prior written notice specifying a different order to the Company to effectuate the foregoing, the Company shall reduce or eliminate the Total Payments by first reducing or eliminating the portion of the Total Payments which are not payable in cash and then by reducing or eliminating cash payments, in each case in reverse order beginning with payments or benefits which are to be paid the farthest in time from the Change in Control. Any notice given by the Executive pursuant to the preceding sentence shall take precedence over the provisions of any other plan, arrangement or agreement governing the Executive’s rights and entitlements to any benefits or compensation. For the avoidance of doubt, in no event shall the Company be required to pay to Executive any amount under this Section 7 with respect to any taxes or interest that may arise as a result of Section 409A of the Code.

8. Non-Competition and Non-Disclosure; Executive Cooperation; Non-Disparagement .

8.2 Ownership of Work . Executive will promptly disclose in writing to the Company all inventions, discoveries, developments, improvements and innovations (collectively referred to as “ Inventions ”) that Executive has conceived or made during the Term; provided, however, that in this context “Inventions” are limited to those which (i) relate in any manner to the existing or contemplated business activities of the Company and its affiliates; (ii) are suggested by or result from Executive’s work at the Company; or (iii) result from the use of the time, materials or facilities of the Company and its affiliates. All Inventions will be the Company’s property rather than Executive’s. Should the Company request it, Executive agrees to sign any document that the Company may reasonably require to establish ownership in any Invention.

8.3 Cooperation With Regard to Litigation . Executive agrees to cooperate with the Company, during the Term and thereafter (including following Executive’s termination of employment for any reason), by making himself available to testify on behalf of the Company or any subsidiary or affiliate of the Company, in any action, suit, or proceeding, whether civil, criminal, administrative, or investigative, and to assist the Company, or any subsidiary or affiliate of the Company, in any such action, suit, or proceeding, by providing information and meeting and consulting with the Board or its representatives or counsel, or representatives or counsel to the Company, or any subsidiary or affiliate of the Company, as may be reasonably requested and after taking into account Executive’s post-termination responsibilities and obligations. The Company agrees to reimburse Executive, on an after-tax basis, for all reasonable expenses actually incurred in connection with his provision of testimony or assistance and to pay a mutually agreed hourly fee to Executive for any assistance provided after termination of Executive’s employment.

8.4 Non-Disparagement . Executive shall not, at any time during the Term and thereafter make statements or representations, or otherwise communicate, directly or indirectly, in writing, orally, or otherwise, or take any action which may, directly or indirectly, disparage or be damaging to the Company, its subsidiaries or affiliates or their respective officers, directors, employees, advisors, businesses or reputations. The members of the Board, the executive officers of the Company and any personnel who are generally responsible for communications with investors and the public (including, without limitation, the Company’s public relations and investor relations personnel) shall not, at any time during the Term and thereafter, make statements or representations, or otherwise communicate, directly or indirectly, in writing, orally or otherwise, or take any action which may, directly or indirectly, disparage or be damaging to Executive or his reputation.

Notwithstanding the foregoing, nothing in this Agreement shall preclude Executive or such members of the Board, executive officers or personnel from making truthful statements that are required by applicable law, regulation or legal process, including truthful statements in connection with an action, suit or other proceeding to enforce Executive’s or the Company’s respective rights under this Agreement.

14

8.5 Release of Employment Claims . Executive agrees, as a condition to receipt of any termination payments and benefits provided for in Sections 4 and 5 herein (other than Compensation Accrued at Termination) (the “ Termination Benefits ”), that he will execute a general release in substantially the form attached hereto as Exhibit C .

8.6 Remedies . Executive agrees that any breach of the terms of this Section 8 would result in irreparable injury and damage to the Company for which the Company would have no adequate remedy at law; Executive therefore also agrees that in the event of said breach or any threat of breach and notwithstanding Section 9 the Company shall be entitled to seek an immediate injunction and restraining order from a court of competent jurisdiction to prevent such breach and/or threatened breach and/or continued breach by Executive and/or any and all persons and/or entities acting for and/or with Executive, without having to prove damages. The availability of injunctive relief shall be in addition to any other remedies to which the Company may be entitled at law or in equity, but remedies other than injunctive relief may only be pursued in an arbitration brought in accordance with Section 9. The terms of this paragraph shall not prevent the Company from pursuing in an arbitration any other available remedies for any breach or threatened breach of this Section 8, including but not limited to the recovery of damages from Executive. Executive hereby further agrees that, if it is ever determined, in an arbitration brought in accordance with Section 9, that willful actions by Executive have constituted wrongdoing that results in an accounting restatement due to the material noncompliance of the Company with financial reporting requirements in any report or statement filed by the Company with the U.S. Securities and Exchange Commission, then the Company, or its successor, as appropriate, may recover all of any bonus or other incentive-based or equity based compensation received by Executive during the 12-month period following the first public issuance or filing with the U.S. Securities and Exchange Commission, whichever first occurs, of the financial document embodying such financial reporting requirement, less the amount of any net tax owed by Executive with respect to such award or payment over the tax benefit to Executive from the repayment or return of the award or payment, pursuant to Sections 5.3 or 5.4. The Company or its successor may, in its sole discretion, affect any such recovery by (i) obtaining repayment directly from Executive; (ii) setting off the amount owed to it against any amount or award that would otherwise be payable by the Company to Executive; or (iii) any combination of (i) and (ii) above.

9. Governing Law; Disputes; Arbitration .

9.1 Governing Law . This Agreement is governed by and is to be construed, administered, and enforced in accordance with the laws of the District of Columbia, without regard to conflicts of law principles. If under the governing law, any portion of this Agreement is at any time deemed to be in conflict with any applicable statute, rule, regulation, ordinance, or other principle of law, such portion shall be deemed to be modified or altered to the extent necessary to conform thereto or, if that is not possible, to be omitted from this Agreement. The invalidity of any such portion shall not affect the force, effect, and validity of the remaining portion hereof. If any court determines that any provision of Section 8 is unenforceable because of the duration or geographic scope of such provision, it is the parties’ intent that such court shall

15

have the power to modify the duration or geographic scope of such provision, as the case may be, to the extent necessary to render the provision enforceable and, in its modified form, such provision shall be enforced.

9.2 Arbitration . Any dispute or controversy arising under or in connection with this Agreement shall be settled exclusively by arbitration in the District of Columbia by a single arbitrator in accordance with the Employment Arbitration Rules and Mediation Procedures of the American Arbitration Association in effect at the time of su
