(i) the Executive’s target annual bonus for the fiscal year in which such termination occurs at 100% of such target annual bonus, pro-rated by the number of calendar days in which the Executive is employed by the Company during the applicable year, including any applicable Notice Period, which shall be paid no later than the tenth business day following the effective date of the Release; and

(iv) continuation of medical insurance coverage for Executive and Executive’s family, subject to COBRA and subject to Executive’s payment of a premium co-pay related to the coverage that is no less favorable than the premium co-pay charged to active employees of the Company electing the same coverage, for twenty-four (24) months from the Separation Date; provided, that the Company shall have no obligation to provide such coverage if Executive fails to elect COBRA benefits in a timely fashion or if Executive becomes eligible for medical coverage with another employer; and provided, that if COBRA continuation coverage is otherwise earlier terminated under applicable law, then, in lieu of coverage, the Company will pay the same amount it paid on a monthly basis for COBRA continuation coverage directly to the Executive each month for the remainder of the relevant period.

(d) Notwithstanding any other provision with respect to the timing of payments, if, at the time of Executive’s termination, Executive is deemed to be a “specified employee” (within the meaning of Code Section 409A, and any successor statute, regulation and guidance thereto) of the Company, then limited only to the extent necessary to comply with the requirements of Code Section 409A, any payments to which Executive may become entitled under this Agreement which are subject to Code Section 409A (and not otherwise exempt from its application) will be withheld until the first (1st) business day of the seventh (7th) month following the termination of Executive’s employment, at which time Executive shall be paid an aggregate amount equal to the accumulated, but unpaid, payments otherwise due to Executive under the terms of this Agreement.

(e) If any payment or benefit Executive would receive under this Agreement, when combined with any other payment or benefit Executive receives pursuant to a Change in Control (“Payment”) would (i) constitute a “parachute payment” within the meaning of Code Section 280G, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be either (x) the full amount of such Payment or (y) such less amount as would result in no portion of the Payment being subject to the Excise Tax, whichever of

the foregoing amounts, taking into account the applicable federal, state, and local employments taxes, income taxes, and the Excise Tax results in Executive’s receipt, on an after-tax basis, of the greater amount of the Payment, notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. The Executive shall be allowed to specify which payment(s) or benefit(s) shall be reduced if necessary to implement this section and avoid the excise tax application. The Company shall provide the Executive with sufficient information to make such determination and to file and pay any required taxes.

4. No Duplication of Compensation. The Severance Compensation shall replace, and be provided in lieu of, any severance or similar compensation that may be provided to the Executive under any other agreement or arrangement in relation to termination of employment; provided, however, that this prohibition against duplication shall not be construed to otherwise limit the Executive’s rights to payments or benefits provided under any pension plan (as defined in Section 3(2) of the Employee Retirement Income Security Act of 1974, as amended), deferred compensation, stock, stock option or similar plan sponsored by the Company.

5. No Mitigation.

Except as set forth in Section 4, the amount of any payment or benefit provided for in this Agreement shall not be reduced by any compensation earned by the Executive as the result of employment by another employer, by retirement benefits, by offset against any amount claimed to be owed by the Executive to the Company, or otherwise.

The Company’s obligations under this Agreement are contingent on the Executive’s execution of the Company’s Proprietary Information, Inventions, and Competition Agreement (the “Proprietary Information Agreement”).

If any provision of this Agreement shall be deemed invalid or unenforceable as written, this Agreement shall be construed, to the greatest extent possible, or modified, to the extent allowable by law, in a manner which shall render it valid and enforceable.

Notices to Executive shall be sent to the last known address in the Company’s records or such other address as Executive may specify in writing. Notices to the Company shall be sent to the Company’s Lead Director, or to such other Company representative as the Company may specify in writing.

9. Claims for Benefits. All claims by the Executive for benefits under this Agreement shall be directed to and determined by the Board and shall be in writing. Any denial by the Board of a claim for benefits under this Agreement shall be delivered to the Executive in writing and shall set forth the specific reasons for the denial and the specific provisions of this Agreement relied upon. The Board shall afford a reasonable opportunity to the Executive for a review of the decision denying a claim and shall further allow the Executive to appeal to the Board a decision of the Board within sixty (60) days after notification by the Board that the Executive’s claim has been denied.

10. Modifications and Amendments. The terms and provisions of this Agreement may be modified or amended only by written agreement executed by the Company and the Executive. The Company and the Executive agree that they will jointly execute an amendment to modify this Agreement to the extent necessary to comply with the requirements of Code Section 409A, or any successor statute, regulation and guidance thereto; provided that no such amendment shall increase the total financial obligation of the Company under this Agreement.

11. Waivers and Consents. The terms and provisions of this Agreement may be waived, or consent for the departure therefrom granted, only by a written document executed by the party entitled to the benefits of such terms or provisions.

None of the rights of the Executive to receive any form of compensation payable pursuant to the Agreement may be assigned or transferred except by will or the laws of descent and distribution.
