2. Term of Employment. Your employment with the Company is at will, which means that your employment is for no specified term, and may be terminated by you or the Company at any time, with or without cause or notice, subject to the provisions of Paragraphs 4 and 5 below.

You will also be entitled to participate in the Company’s FY2012 Annual Incentive Plan with a target of $288,750, prorated for the portion of FY2012 falling between your start date and the end of FY2012.

You agree that if you voluntarily terminate your employment with the Company for any reason, you will provide the Company with at least 10 business days’ written notice of your resignation. The Company shall have the option, in its sole discretion, to make your resignation effective at any time prior to the end of such notice period, provided the Company pays you an amount equal to the base salary and benefits you would have earned through the end of the notice period.

5. Other Termination. Your employment may be terminated under the circumstances set forth below.

(a) Termination by Disability: If, by reason of any physical or mental incapacity, you have been or will be prevented from performing your then-current duties under this Agreement with reasonable accommodation, then, to the extent permitted by law, the Company may terminate your employment without any advance notice. Upon such termination, if you sign a general release of known and unknown claims in a form satisfactory to the Company which becomes valid and irrevocable within 60 days of your termination, and you fully comply with your obligations under Paragraphs 7, 8, and 10, the Company will provide you with the severance payments and benefits described in Paragraph 5(c). Nothing in this paragraph shall

affect your rights under any applicable Company disability plan; provided, however, that your severance payments will be offset by any disability income payments received by you so that the total monthly severance and disability income payments during your severance period shall not exceed your then-current base salary.

(b) Termination for Cause: The Company may terminate your employment at any time for cause (as described below) without providing any notice (except to the extent expressly provided below). If your employment is terminated by the Company for cause, you shall be entitled to no compensation or benefits from the Company other than those earned under Paragraph 3 through the date of termination. For purposes of this Agreement, a termination for “cause” occurs if you are terminated for any of the following reasons: (i) theft, dishonesty, misconduct or falsification of any employment or Company records; (ii) improper disclosure of the Company’s confidential or proprietary information; (iii) any action by you which has a material detrimental effect on the Company’s reputation or business; (iv) your refusal or inability to perform any assigned duties (other than as a result of a disability), after written notice from the Company to you of, and a 30-day opportunity to cure, such refusal or inability; (v) your material breach of this Agreement or of the employee proprietary information/confidentiality/assignment of inventions agreement not otherwise described in this paragraph, after written notice from the Company to you of, and a 30-day opportunity to cure, such breach; or (vi) your conviction (including any plea of guilty or no contest) for any criminal act that impairs your ability to perform your duties under this Agreement.

(c) Termination Without Cause: The Company may terminate your employment without cause at any time with or without advance notice. If your employment is terminated by the Company without cause, and you sign a general release of known and unknown claims in a form satisfactory to the Company within the applicable review period which thereupon is (or, if any revocation period is required by law, following expiration of such period becomes) valid and irrevocable within 60 days of your termination, and you fully comply with your obligations under Paragraphs 7, 8, and 10, you will receive the following severance benefits:

(i) payments at your final base salary rate for a period of twelve (12) months following your termination; such payments will be subject to applicable withholding and made in accordance with the Company’s normal payroll practices; provided, however, that any such payments that would have been paid in accordance with the Company’s normal payroll practices before your release becomes valid and irrevocable will accumulate and be paid only if and when both (x) your release becomes valid and irrevocable and (y) such validity and irrevocability in no event occurs more than 60 days after your termination;

(ii) payment of the premiums necessary to continue your group health insurance under the Consolidated Omnibus Budget Reconciliation Act (“COBRA”) provided you have timely elected COBRA coverage until the earlier of (x) twelve (12) months following your termination date; or (y) the date you first became eligible to participate in another employer’s group health insurance plan; or (z) the date on which you are no longer eligible for COBRA coverage;

(iii) the Company will pay you the prorated portion of any incentive bonus that you would have earned, if any, during the incentive bonus period in which your employment terminates (the pro-ration shall be equal to the percentage of that bonus period that you are actually employed by the Company), and such prorated bonus will be paid to you at the time that such incentive bonuses are paid to other Company employees, or at any earlier time required by applicable law;

(iv) with respect to any stock options or other equity-related awards granted to you by the Company, you will cease vesting upon your termination date; however, you will be entitled to purchase any vested shares of stock that are subject to those options until the earlier of (x) twelve (12) months following your termination date, or (y) the date on which the applicable option(s) expire(s); except as set forth in this subparagraph, your Company stock options and other equity-related awards will continue to be subject to and governed by the Company’s Stock Equity Plan (as amended from time to time, the “Plan”) and the applicable agreements between you and the Company; and

(v) reasonable outplacement assistance selected and paid for by the Company.

(d) Resignation for Good Reason: If you resign from your employment with the Company for Good Reason (as defined in this paragraph), and such resignation does not qualify as a resignation for Good Reason Following a Change of Control (as defined in Paragraph 6(b), and you sign a general release of known and unknown claims in a form satisfactory to the Company within the applicable review period which thereupon is (or, if any revocation period is required by law, following expiration of such period becomes) valid and irrevocable within 60 days of your termination, and you fully comply with your obligations under Paragraphs 7, 8, and 10, you shall receive the severance benefits described in Paragraph 5(c).

To the extent that any of the payments and benefits provided for in this Agreement or otherwise payable to you (the “Payments”) constitute “parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), the amount of such Payments shall be either:

whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the Excise Tax, results in the receipt by you, on an after-tax basis, of the greatest amount of benefit. In the event that any Excise Tax is imposed on the Payments, you will be fully responsible for the payment of any and all Excise Tax, and the Company will not be obligated to pay all or any portion of any Excise Tax.

11. Dispute Resolution. The parties agree that any suit, action, or proceeding arising out of or relating to this Agreement, the parties’ employment relationship, or the termination of that relationship for any reason, shall be brought in the appropriate state or federal court appropriate for disputes arising in Santa Clara, California, and you agree to submit to the personal jurisdiction of such court. The parties irrevocably waive, to the fullest extent permitted by law, any objection they may have to the laying of venue for any such suit, action or proceeding brought in such court. If any one or more provisions of this Paragraph 11 shall for any reason be held invalid or unenforceable, it is the specific intent of the parties that such provisions shall be modified to the minimum extent necessary to make it or its application valid and enforceable.

12. Compliance with Section 409A of the Internal Revenue Code. This Agreement is intended to comply with, or otherwise be exempt from, Section 409A of the Code and the rules and regulations promulgated thereunder (collectively, “Section 409A”). However, the Company has not made and is making no representation to you relating to the tax treatment of any payment pursuant to this Agreement under Section 409A and the corresponding provisions of any applicable State income tax laws.

Notwithstanding anything to the contrary in this Agreement, any payments or benefits due hereunder upon a termination of employment which are a “deferral of compensation” within the meaning of Section 409A shall only be payable or provided to you upon a “separation from service” as defined for purposes of Section 409A. In addition, if you are a “specified employee” as determined pursuant to Section 409A as of the date of your separation from service, as so defined, and if any payments or entitlements provided for in this Agreement constitute a “deferral of compensation” within the meaning of Section 409A and cannot be paid or provided in the manner provided herein without subjecting you to additional tax, interest or penalties under Section 409A, then any such payment or entitlement which is otherwise payable during the first six months following your separation from service shall be paid or provided to you in a lump sum on the earlier of (i) the first business day of the seventh calendar month immediately following the month in which your separation from service occurs or (ii) the date of your death. To the extent required to satisfy the provisions of the foregoing sentence with respect to any benefit to be provided in-kind, the Company shall bill you, and you shall promptly pay, the value for tax purposes of any such benefit and the Company shall therefore promptly refund the amount so paid by you as soon as allowed by the foregoing sentence.

For purposes of Section 409A, the right to a series of installment payments under this Agreement shall be treated as a right to a series of separate payments. With respect to any reimbursement of your expenses, or any provision of in-kind benefits to you, as specified under this Agreement, such reimbursement of expenses or provision of in-kind benefits shall be subject to the following conditions: (1) the expenses eligible for reimbursement or the amount of in-kind benefits provided in one taxable year shall not affect the expenses eligible for reimbursement or the amount of in-kind benefits provided in any other taxable year, except for any medical reimbursement arrangement providing for the reimbursement of expenses referred to in Section

9

Edward J. Hayes, Jr.

Employment Agreement

105(b) of the Code; (2) the reimbursement of an eligible expense shall be made no later than the end of the year after the year in which such expense was incurred; and (3) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit.

13. Severability. If any provision of this Agreement is deemed invalid, illegal or unenforceable, such provision shall be modified so as to make it valid, legal and enforceable, and the validity, legality and enforceability of the remaining provisions of this Agreement shall not in any way be affected.

14. Confirmation of Rights which Are not Dependent Upon Signing a Release. Whether or not you sign a release as provided in certain provisions of this Agreement, (a) you will be paid all wages due, including any unused accrued vacation, as of your last day of work, (b) your health care coverage as a primary insured under the Company’s health plan will continue through the end of the month in which your last day of work falls, (c) thereafter, you will be eligible for continuation of health insurance at your own expense if you timely elect coverage under COBRA, and (d) you will receive information regarding your right to continue health insurance under COBRA.

15. Applicable Withholding. All salary, bonus, severance and other payments identified in this Agreement are subject to applicable withholding by the Company.

16. Assignment. In view of the personal nature of the services to be performed under this Agreement by you, you cannot assign or transfer any of your obligations under this Agreement.

17. Entire Agreement. This Agreement and the agreements referred to above constitute the entire agreement between you and the Company regarding the terms and conditions of your employment, and they supersede all prior negotiations, representations or agreements between you and the Company regarding your employment, whether written or oral. This Agreement sets forth our entire agreement regarding the Company’s obligation to provide you with severance benefits upon any termination of your employment, and you shall not be entitled to receive any other severance benefits from the Company pursuant to any Company severance plan, policy or practice.

18. Governing Law. This Agreement shall be governed by and construed in accordance with the law of the State of California.

19. Modification. This Agreement may only be modified or amended by a supplemental written agreement signed by you and an authorized representative of the Board.
