(a) The initial term of this Agreement (the “Term”) shall continue until the earlier of (i) the second anniversary of the Effective Date, or (ii) the date on which all payments or benefits required to be made or provided hereunder have been made or provided in their entirety, except to the extent the Term is automatically extended pursuant to Section 2(b).

(b) Notwithstanding the provisions of Section 2(a), the then-effective Term shall automatically be extended in the event that the Term would otherwise expire during the period commencing upon the first public announcement of a definitive agreement that would result in a Change in Control (even though still subject to approval of the Company’s stockholders and other conditions and contingencies) and ending on the date that is eighteen (18) months following the occurrence of such Change in Control. Such extension shall be upon the terms and conditions of this Agreement as then in effect, provided that such extension of the Term of this Agreement shall expire upon the first to occur of the first public announcement of the termination of such definitive agreement or the date that is eighteen (18) months following the occurrence of such Change in Control.

(c) Notwithstanding the provisions of Sections 2(a) and (b), the obligation of the Company to make payments or provide benefits pursuant to this Agreement to which Executive has acquired a right in accordance with the applicable provisions of this Agreement prior to the expiration of the Term shall survive the termination of this Agreement until such payments and benefits have been provided in full.

3. Severance.

(a) If Executive has a Separation from Service as a result of Executive’s discharge by the Company without Cause or by reason of Executive’s resignation for Good Reason or as a result of Executive’s death or Permanent Disability, in any case within eighteen (18) months following a Change in Control, Executive shall be entitled to receive, in lieu of any severance benefits to which Executive may otherwise be entitled under any severance plan or program of the Company, the benefits provided below, which, with respect to clause (ii) and the last sentence of clause (iii) below, if applicable, will be payable in a lump sum within ten (10) days following the effective date of the Release (as defined below):

(i) The Company shall pay to Executive (or his or her estate, if applicable) his or her fully earned but unpaid base salary, when due, through the date of Executive’s Separation from Service at the rate then in effect, plus all other benefits, if any, under any Company group retirement plan, nonqualified deferred compensation plan, equity award plan or agreement (other than any such plan or agreement pertaining to Stock Awards whose treatment is prescribed by Section 3(a)(iii) below), health benefits plan or other Company group benefit plan to which Executive (or his or her estate, if applicable) may be entitled pursuant to the terms of such plans or agreements at the time of Executive’s Separation from Service;

(ii) Subject to Section 3(c) and, other than in the case of Executive’s death, Executive’s continued compliance with Section 4, Executive shall be entitled to receive severance pay in an amount equal to one hundred percent (100%) multiplied by Executive’s annual base salary as in effect immediately prior to the date of Executive’s Separation from Service as well as payment of any amount equal to any annual bonus to which Executive would have been entitled to receive as of the date of Executive’s Separation from Service based on the Company’s and/or Executive’s performance through such date, to be determined by the Board or the Compensation Committee thereof in good faith in

3

accordance with the terms of the applicable bonus program (for the avoidance of doubt, any bonus or part thereof that relates to goals or objectives covering a full calendar year will not be paid unless Executive’s Separation from Service occurs after the end of such calendar year);

(iii) Subject to Section 3(c) and, other than in the case of Executive’s death, Executive’s continued compliance with Section 4, for the period beginning on the date of Executive’s Separation from Service and ending on the date which is twelve (12) full months following the date of Executive’s Separation from Service (or, if earlier, the date on which the applicable continuation period under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) expires) (the “COBRA Coverage Period”), the Company shall arrange to provide Executive and/or his or her eligible dependents who were covered under the Company’s health insurance plans as of the date of Executive’s Separation from Service with health (including medical and dental) insurance benefits substantially similar to those provided to Executive and his or her dependents immediately prior to the date of such Separation from Service. If the Company is not reasonably able to continue health insurance benefits coverage under the Company’s insurance plans, the Company shall provide substantially equivalent coverage under other third-party insurance sources. If any of the Company’s health benefits are self-funded as of the date of Executive’s Separation from Service, or if the Company cannot provide the foregoing benefits in a manner that is exempt from or otherwise compliant with applicable law (including, without limitation, Section 409A of the Code and Section 2716 of the Public Health Service Act), instead of providing continued health insurance benefits as set forth above, the Company shall instead pay to Executive (or his or her estate, if applicable) an amount equal to the monthly premium payment for Executive and/or his or her eligible dependents who were covered under the Company’s health plans as of the date of Executive’s Separation from Service (calculated by reference to the premium as of the date of Separation from Service) as currently taxable compensation in substantially equal monthly installments over the COBRA Coverage Period (or the remaining portion thereof);

(iv) Subject to Section 3(c) and, other than in the case of Executive’s death, Executive’s continued compliance with Section 4, the vesting of each of Executive’s Stock Awards shall be accelerated in full (provided that any Stock Awards that vest upon achievement of any performance-based goals or targets shall be accelerated as to the “target” number of shares subject to such Stock Awards) effective as of the date of Executive’s Separation from Service. Nothing in this Section 3(a)(iv) shall be construed to limit any more favorable vesting applicable to Executive’s Stock Awards in the Company’s equity plan(s) and/or the stock award agreements under which the Stock Awards were granted. The foregoing provisions are hereby deemed to be a part of each Stock Award and to supersede any less favorable provision in any agreement or plan regarding such Stock Award; and

(v) Notwithstanding any other provision of this Agreement to the contrary, any severance benefits payable to Executive under this Agreement shall be reduced by any severance benefits payable by the Company or an affiliate of the Company to such individual under any other policy, plan, program, agreement or arrangement, including, without limitation, any severance agreement between such individual and any entity.

(b) Other Terminations. If Executive’s employment is terminated by the Company without Cause or by Executive for Good Reason prior to a Change in Control or more than eighteen (18) months following a Change in Control, or at any time by the Company for Cause, by Executive without Good Reason, the Company shall not have any other or further obligations to Executive under this Agreement (including any financial obligations) except that Executive shall be entitled to receive (i) Executive’s fully earned but unpaid base salary, through the date of termination at the rate then in effect, and (ii) all other amounts or benefits to which Executive is entitled under any compensation, retirement or benefit plan or practice of the Company at the time of termination in accordance with the terms of such plans or practices, including, without limitation, any continuation of benefits required by COBRA or applicable law. In addition, all vesting of Executive’s unvested Stock Awards previously granted to him

4

or her by the Company shall cease and none of such unvested Stock Awards shall be exercisable following the date of such termination. The foregoing shall be in addition to, and not in lieu of, any and all other rights and remedies which may be available to the Company under the circumstances, whether at law or in equity.

(c) Release. As a condition to Executive’s (or his or her estate’s, if applicable) receipt of any post-termination benefits pursuant to Section 3(a) above, Executive (or, in the event of Executive’s death, the legal representative of his or her estate, or in the event of Executive’s incapacity as a result of his or her Permanent Disability, his or her legal representative) shall execute and not revoke a general release of all claims in favor of the Company (the “Release”) in the form substantially similar to that attached hereto as Exhibit A (and any applicable revocation period applicable to such Release shall have expired) within the sixty (60) day period following the date of Executive’s Separation from Service.

(d) Exclusive Remedy. Except as otherwise expressly required by law (e.g., COBRA) or as specifically provided herein, all of Executive’s rights to salary, severance, benefits, bonuses and other amounts hereunder (if any) accruing after the termination of Executive’s employment shall cease upon such termination. In the event of a termination of Executive’s employment with the Company, Executive’s (or his or her estate’s) sole remedy shall be to receive the payments and benefits described in this Section 3.

(e) No Mitigation. Except as otherwise provided in Section 3(a)(iii) above, Executive shall not be required to mitigate the amount of any payment provided for in this Section 3 by seeking other employment or otherwise, nor shall the amount of any payment or benefit provided for in this Section 3 be reduced by any compensation earned by Executive as the result of employment by another employer or self-employment or by retirement benefits; provided, however, that loans, advances or other amounts owed by Executive to the Company may be offset by the Company against amounts payable to Executive (or his or her estate, if applicable) under this Section 3.

(f) Return of the Company’s Property. If Executive’s employment is terminated for any reason, the Company shall have the right, at its option, to require Executive to vacate his or her offices prior to or on the effective date of termination and to cease all activities on the Company’s behalf. Upon the termination of his or her employment in any manner, as a condition to Executive’s receipt of any post-termination benefits described in this Agreement, Executive (or his or her estate, if applicable) shall immediately surrender to the Company all lists, books and records of, or in connection with, the Company’s business, and all other property belonging to the Company, it being distinctly understood that all such lists, books and records, and other documents, are the property of the Company. Executive (or his or her estate, if applicable) shall deliver to the Company a signed statement certifying compliance with this Section 3(f) prior to the receipt of any post-termination benefits described in this Agreement.

(g) Best Pay Provision.

(i) If any payment or benefit Executive would receive under this Agreement, when combined with any other payment or benefit Executive receives pursuant to the termination of Executive’s employment with the Company (“Payment”), would (A) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (B) 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 (1) the full amount of such Payment or (2) such lesser amount (with cash payments being reduced before stock option compensation) 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 employment 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.

5

(ii) All determinations required to be made under this Section 3(g), including whether and to what extent the Payments shall be reduced and the assumptions to be utilized in arriving at such determination, shall be made by the nationally recognized certified public accounting firm used by the Company immediately prior to the effective date of the Change in Control or, if such firm declines to serve, such other nationally recognized certified public accounting firm as may be designated by the Company (the “Accounting Firm”). The Accounting Firm shall provide detailed supporting calculations both to Executive and the Company at such time as is requested by the Company. All fees and expenses of the Accounting Firm shall be borne solely by the Company. Any determination by the Accounting Firm shall be binding upon Executive and the Company. For purposes of making the calculations required by this Section 3(g), the Accounting Firm may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good-faith interpretations concerning the application of Sections 280G and 4999 of the Code.

4. Confidentiality and Proprietary Rights. Executive and the Company have executed the Company’s Confidentiality and Proprietary Rights Agreement, a copy of which is attached to this Agreement as Exhibit B and incorporated herein by reference (the “Confidentiality and Proprietary Rights Agreement”). The Company shall be entitled to cease all severance payments and benefits to Executive in the event of his or his material breach of this Section 4.

5. Agreement to Arbitrate. Any dispute, claim or controversy based on, arising out of or relating to Executive’s employment or this Agreement shall be settled by final and binding arbitration in San Jose, California, before a single neutral arbitrator in accordance with the National Rules for the Resolution of Employment Disputes (the “Rules”) of the American Arbitration Association (“AAA”), and judgment on the award rendered by the arbitrator may be entered in any court having jurisdiction.¹ Arbitration may be compelled pursuant to the California Arbitration Act (Code of Civil Procedure §§ 1280 et seq.). If the parties are unable to agree upon an arbitrator, one shall be appointed by the AAA in accordance with its Rules. Each party shall pay the fees of its own attorneys, the expenses of its witnesses and all other expenses connected with presenting its case; provided, however, Executive and the Company agree that, to the extent permitted by law, the arbitrator may, in his or her discretion, award reasonable attorneys’ fees to the prevailing party; provided, further, that the prevailing party shall be reimbursed for such fees, costs and expenses within forty-five (45) days following any such award, but in no event later than the last day of the Executive’s taxable year following the taxable year in which the fees, costs and expenses were incurred; provided, further, that the parties’ obligations pursuant to this sentence shall terminate on the tenth (10^th) anniversary of the date of Executive’s termination of employment; provided, however, that Executive shall retain the right to file administrative charges with or seek relief through any government agency of competent jurisdiction, and to participate in any government investigation, including but not limited to (a) claims for workers’ compensation, state disability insurance or unemployment insurance; (b) claims for unpaid wages or waiting time penalties brought before the California Division of Labor Standards Enforcement; provided, however, that any appeal from an award or from denial of an award of wages and/or waiting time penalties shall be arbitrated pursuant to the terms of this Agreement; and (c) claims for administrative relief from the United States Equal Employment Opportunity Commission and/or the California Department of Fair Employment and Housing (or any similar agency in any applicable jurisdiction other than California); provided, further, that Executive shall not be entitled to obtain any monetary relief through such agencies other than workers’ compensation benefits or unemployment insurance benefits. Other costs of the arbitration, including the cost of any record or transcripts of the arbitration, AAA’s administrative fees, the fee of the arbitrator, and all other fees and costs, shall be borne by the Company. This Section 5 is intended to be the exclusive method for resolving any and all claims by the parties against each other for

6

payment of damages under this Agreement or relating to Executive’s employment; provided, however, that neither this Agreement nor the submission to arbitration shall limit the parties’ right to seek provisional relief, including without limitation injunctive relief, in any court of competent jurisdiction pursuant to California Code of Civil Procedure § 1281.8 or any similar statute of an applicable jurisdiction. Seeking any such relief shall not be deemed to be a waiver of such party’s right to compel arbitration. Both Executive and the Company expressly waive their right to a jury trial.

6. At-Will Employment Relationship. Executive’s employment with the Company is at-will and not for any specified period and may be terminated at any time, with or without Cause or advance notice, by either Executive or the Company. Any change to the at-will employment relationship must be by specific, written agreement signed by Executive and an authorized representative of the Company. Nothing in this Agreement is intended to or should be construed to contradict, modify or alter this at-will relationship.

7. General Provisions.

7.1 Successors and Assigns. The rights of the Company under this Agreement may, without the consent of Executive, be assigned by the Company, in its sole and unfettered discretion, to any person, firm, corporation or other business entity which at any time, whether by purchase, merger or otherwise, directly or indirectly, acquires all or substantially all of the assets or business of the Company. The Company will require any successor (whether direct or indirect, by purchase, merger or otherwise) to all or substantially all of the business or assets of the Company expressly to assume and to agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place; provided, however, that no such assumption shall relieve the Company of its obligations hereunder; provided, further, that the failure of any such successor to so assume this Agreement shall constitute a material breach of this Agreement. As used in this Agreement, the “Company” shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which assumes and agrees to perform this Agreement by operation of law or otherwise. Executive shall not be entitled to assign any of Executive’s rights or obligations under this Agreement. This Agreement shall inure to the benefit of and be enforceable by Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees.

7.2 Severability. In the event any provision of this Agreement is found to be unenforceable by an arbitrator or court of competent jurisdiction, such provision shall be deemed modified to the extent necessary to allow enforceability of the provision as so limited, it being intended that the parties shall receive the benefit contemplated herein to the fullest extent permitted by law. If a deemed modification is not satisfactory in the judgment of such arbitrator or court, the unenforceable provision shall be deemed deleted, and the validity and enforceability of the remaining provisions shall not be affected thereby.

7.3 Interpretation; Construction. The headings set forth in this Agreement are for convenience only and shall not be used in interpreting this Agreement. This Agreement has been drafted by legal counsel representing the Company, but Executive has participated in the negotiation of its terms. Furthermore, Executive acknowledges that Executive has had an opportunity to review and revise the Agreement and have it reviewed by legal counsel, if desired, and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of this Agreement. Either party’s failure to enforce any provision of this Agreement shall not in any way be construed as a waiver of any such provision, or prevent that party thereafter from enforcing each and every other provision of this Agreement.

7.4 Governing Law and Venue. This Agreement will be governed by and construed in accordance with the laws of the United States and the State of California applicable to contracts made and to be performed wholly within such State, and without regard to the conflicts of laws principles

7

thereof. Any suit brought hereon shall be brought in the state or federal courts sitting in Santa Clara County, California, the Parties hereby waiving any claim or defense that such forum is not convenient or proper. Each party hereby agrees that any such court shall have in personam jurisdiction over it and consents to service of process in any manner authorized by California law.

7.5 Notices. Any notice required or permitted by this Agreement shall be in writing and shall be delivered as follows with notice deemed given as indicated: (a) by personal delivery when delivered personally; (b) by overnight courier upon written verification of receipt; (c) by telecopy or facsimile transmission upon acknowledgment of receipt of electronic transmission; or (d) by certified or registered mail, return receipt requested, upon verification of receipt. Notice shall be sent to Executive at the address set forth below and to the Company at its principal place of business, or such other address as either party may specify in writing.

7.6 Survival. Sections 1 (“Definitions”), 3 (“Severance”), 4 (“Confidentiality and Proprietary Rights”), 5 (“Agreement to Arbitrate”) and 7 (“General Provisions”) of this Agreement shall survive termination of Executive’s employment by the Company.

7.7 Entire Agreement. This Agreement and the Confidentiality and Proprietary Rights Agreement incorporated herein by reference together constitute the entire agreement between the parties in respect of the subject matter contained herein and therein and supersede all prior or simultaneous representations, discussions, negotiations, and agreements, whether written or oral, including, without limitation, any offer letter executed by the Company and Executive in connection with Executive’s commencement of employment. This Agreement may be amended or modified only with the written consent of Executive and an authorized representative of the Company. No oral waiver, amendment or modification will be effective under any circumstances whatsoever.

7.8 Code Section 409A Exempt.

(a) This Agreement is not intended to provide for any deferral of compensation subject to Section 409A of the Code, and, accordingly, the severance payments payable under Section 3(a)(ii) and the last sentence of Section 3(a)(iii), if applicable, shall be paid no later than the later of: (i) the fifteenth (15^th) day of the third month following Executive’s first taxable year in which such severance benefit is no longer subject to a substantial risk of forfeiture, and (ii) the fifteenth (15^th) day of the third month following first taxable year of the Company in which such severance benefit is no longer subject to substantial risk of forfeiture, as determined in accordance with Code Section 409A and any Treasury Regulations and other guidance issued thereunder. To the extent applicable, this Agreement shall be interpreted in accordance with Code Section 409A and Department of Treasury regulations and other interpretive guidance issued thereunder. Each series of installment payments made under this Agreement is hereby designated as a series of “separate payments” within the meaning of Section 409A of the Code.

(b) If the Executive is a “specified employee” (as defined in Section 409A of the Code), as determined by the Company in accordance with Section 409A of the Code, on the date of the Executive’s Separation from Service, to the extent that the payments or benefits under this Agreement are subject to Section 409A of the Code and the delayed payment or distribution of all or any portion of such amounts to which Executive is entitled under this Agreement is required in order to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code, then such portion deferred pursuant to this Section 7.8(b) shall be paid or distributed to Executive in a lump sum on the earlier of (i) the date that is six (6)-months following Executive’s Separation from Service, (ii) the date of Executive’s death or (iii) the earliest date as is permitted under Section 409A of the Code. Any remaining payments due under the Agreement shall be paid as otherwise provided herein.

7.9 Consultation with Legal and Financial Advisors. By executing this Agreement, Executive acknowledges that this Agreement confers significant legal rights, and may also involve the waiver of rights under other agreements; that the Company has encouraged Executive to consult with Executive’s personal legal and financial advisors; and that Executive has had adequate time to consult with Executive’s advisors before executing this Agreement.

7.10 Counterparts. This Agreement may be executed in multiple counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument.

3. Severability. In the event any provision of this Release is found to be unenforceable by an arbitrator or court of competent jurisdiction, such provision shall be deemed modified to the extent necessary to allow enforceability of the provision as so limited, it being intended that the parties shall receive the benefit contemplated herein to the fullest extent permitted by law.

Either party’s failure to enforce any provision of this Release shall not in any way be construed as a waiver of any such provision, or prevent that party thereafter from enforcing each and every other provision of this Release.
