The provisions of this Section 4 shall apply to all Equity Awards granted prior to the August 7, 2008 amendment and restatement of the Plan with respect to individuals who were Participants as of that date. In addition, this Section 4 shall apply to any Equity Award that the Committee designates at the time of grant, or subsequent to the grant, as being subject to this Section 4. For the treatment of all other Equity Awards, see Section 4A, below.

In the event of a Change in Control in which the Acquiror does not assume or continue any of then-outstanding Options or Stock Appreciation Rights held by the Participant or substitute for any such awards substantially equivalent awards for the Acquiror’s stock, then the vesting, exercisability and settlement of each such award which is not assumed, continued or substituted for shall be accelerated in full effective immediately prior to but conditioned upon the consummation of the Change in Control.

4.2    Options and Stock Appreciation Rights – Assumed or Substituted. In the event of a Change in Control in which the Acquiror assumes or continues the Company’s rights and obligations under any of the then-outstanding Options or Stock Appreciation Rights held by the Participant or substitutes for any such awards substantially equivalent awards for the Acquiror’s stock, then the vesting, exercisability and settlement of each such award which is assumed, continued or substituted for shall be determined as follows:

(a)    As of the effective date of the Change in Control, the number of shares subject to such award treated as vested and exercisable pursuant to such award shall be equal to the sum of (i) the number of shares vested and exercisable determined in accordance with the schedule set forth in the agreement or certificate evidencing such award and (ii) a number of shares equal to fifty percent (50%) of the difference between the total number of shares subject to the award and the number of vested shares subject to the award, rounded down to the nearest whole number.

4.3    Effect On Option and Stock Appreciation Rights Agreements. The provisions contained in Sections 4.1 and 4.2 of this Plan shall apply notwithstanding any provision to the contrary contained in any agreement evidencing an Option or Stock Appreciation Right granted to a Participant to the extent such agreement confers lesser rights to the Participant.

4.4    Other Equity Awards. Notwithstanding any provision to the contrary contained in any agreement evidencing a Restricted Stock, Restricted Stock Unit or other stock-based compensation award held by a Participant, the vesting, exercisability and settlement of such Equity Awards shall be accelerated in full effective immediately prior to the consummation of a Change in Control, provided that the Participant remains an employee or other service provider with the Company Group immediately prior to the Change in Control.

The provisions of this Section 4A shall apply to all Equity Awards granted on or after the effective date of the amendment and restatement of the Plan.

In the event of a Change in Control in which the Acquiror assumes or continues the Company’s rights and obligations under any of the then-outstanding Equity Awards held by the Participant or substitutes for any such Equity Awards substantially equivalent awards, then the vesting, exercisability and settlement of each such Equity Award shall vest and become exercisable or settleable as determined in accordance with the agreement applicable to such award as in effect immediately prior to the Change in Control.

The provisions contained in Section 4A.1 of this Plan shall apply notwithstanding any provision to the contrary contained in any agreement evidencing an Equity Award granted to a Participant to the extent such agreement confers lesser rights to the Participant.

5.    TERMINATION UPON A CHANGE IN CONTROL

In the event of a Participant’s Termination Upon a Change in Control, the Participant shall be entitled to receive the compensation and benefits described in his or her Participation Agreement and this Section 5. The provision, time and manner of payment or distribution of all such compensation and benefits shall be subject to, limited by and construed in accordance with the requirements of Section 409A of the Code, to the extent applicable, including any delay in payments after a Termination Upon a Change in Control of a Specified Employee required by Section 409A.

5.1    Accrued Obligations. The Participant shall be entitled to receive:

(d)    payment within ten (10) business days following the Participant’s termination of employment of any Prior Year Bonus or portion thereof which the Committee determines has been earned by the Participant as of the date of the Participant’s termination of employment under the terms of the programs, plans or agreements providing for such bonus, but which remains unpaid as of such date;

(e)    reimbursement within ten (10) business days of submission of proper expense reports of all expenses reasonably and necessarily incurred by the Participant in connection with the business of the Company Group prior to his or her termination of employment; and

(f)    the benefits, if any, under any Company Group retirement plan, nonqualified deferred compensation plan, stock purchase or other stock-based compensation plan or agreement (other than any such plan or agreement pertaining to Equity Awards whose treatment is prescribed by Section 5.2(c) below), health benefits plan or other Company Group benefit plan to which the Participant may be entitled pursuant to the terms of such plans or agreements.

5.2    Severance Benefits. Provided that the Participant executes and such Release has become effective in accordance with its terms prior to the Release Deadline, the Participant shall be entitled to receive the following severance payments and benefits:

(a)    Salary and Bonus. On the first payroll date following the last to occur of (i) the Release Deadline; and (ii) if the Participant is a Specified Employee, six months after the date of the Participant’s Separation from Service, the Company shall pay to the Participant in a lump sum cash payment an amount equal to the sum of (1) the Participant’s Base Salary Rate multiplied by the number of months in the Severance Benefit Period applicable to the Participant and (2) the Participant’s Annual Bonus multiplied by a ratio, the numerator of which is the number of months in the Severance Benefit Period applicable to the Participant and the denominator of which is twelve (12).

(b)    Health Insurance Benefits. For the period commencing immediately following the Participant’s Separation from Service and continuing for the duration of the number of months in the Participant’s Severance Benefit Period, the Company shall arrange to provide the Participant and his or her dependents with health insurance benefits (including medical, dental and vision) substantially similar to those provided to the Participant and his or her dependents immediately prior to the date of such termination of employment (without giving effect to any reduction in such benefits constituting Good Reason). Such benefits shall be provided to the Participant at the same premium cost to the Participant and at the same coverage level as in effect as of the Participant’s termination of employment (without giving effect to any reduction in such benefits constituting Good Reason); provided, however, that the Participant shall be subject to any change in the premium cost and/or level of coverage applicable generally to all employees

holding the position or comparable position with the Company which the Participant held immediately prior to the Change in Control. The Company may satisfy its obligation to provide a continuation of health insurance benefits by paying that portion of the Participant’s premiums required under the Consolidated Omnibus Budget Reconciliation Act (“COBRA”) that exceed the amount of premiums that the Participant would have been required to pay for continuing coverage had he or she continued in employment. If the Company is not reasonably able to continue such coverage under the Company’s benefit plans, the Company shall provide substantially equivalent coverage under other sources or will reimburse the Participant for premiums (in excess of the Participant’s premium cost described above) incurred by the Participant to obtain his or her own such substantially equivalent coverage. If the Participant becomes eligible to receive such coverage under another employer’s benefit plans during the applicable Severance Benefit Period, the Participant shall report such eligibility to the Company, and the Company’s obligations under this Section 5.2(b) shall be secondary to the coverage provided by such other employer’s plans. For the balance of any period in excess of the applicable Severance Benefit Period during which the Participant is entitled to continuation coverage under COBRA, the Participant shall be entitled to maintain coverage for himself or herself and the Participant’s eligible dependents at the Participant’s own expense.

(c)    Acceleration of Vesting of Equity Awards. Notwithstanding any provision to the contrary contained in any agreement evidencing an Equity Award granted to a Participant, the vesting, exercisability and settlement of each of the Participant’s outstanding Equity Awards shall be accelerated in full effective as of the date of the Participant’s Separation from Service so that each Equity Award held by the Participant shall be immediately exercisable and fully vested (and, in the case of Restricted Stock Units, shall be settled in full), as of the date of the Participant’s Separation from Service.

(a)    In addition to any rights a Participant may have under any indemnification agreement previously entered into between the Company and such Participant (a “Prior Indemnity Agreement”), from and after the date of the Participant’s termination of employment, the Company shall indemnify and hold harmless the Participant against any costs or expenses (including attorneys’ fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, by reason of the fact that the Participant is or was a director, officer, employee or agent of the Company Group, or is or was serving at the request of the Company Group as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, whether asserted or claimed prior to, at or after the date of the Participant’s termination of employment, to the fullest extent permitted under applicable law, and the Company shall also advance fees and expenses (including attorneys’ fees) as incurred by the Participant to the fullest extent permitted under applicable law. In the event of a conflict between the provisions of a Prior Indemnity Agreement and the provisions of this Plan, the Participant may elect which provisions shall govern.

(b)    For a period of six (6) years from and after the date of termination of employment of a Participant who was an officer and/or director of the Company at any time prior

to such termination of employment, the Company shall maintain a policy of directors’ and officers’ liability insurance for the benefit of such Participant which provides him or her with coverage no less favorable than that provided for the Company’s continuing officers and directors.

6.1    Excess Parachute Payment. In the event that any payment or benefit received or to be received by the Participant pursuant to this Plan or otherwise (collectively, the “Payments”) would subject the Participant to any excise tax pursuant to Section 4999 of the Code (the “Excise Tax”) due to the characterization of such Payments as an excess parachute payment under Section 280G of the Code, then, notwithstanding the other provisions of this Plan, the amount of such Payments will not exceed the amount which produces the greatest after-tax benefit to the Participant. For purposes of this Section 6.1, if Payments must be reduced, then such reductions shall come first from the cash severance otherwise payable to the Participant.

6.2    Determination by Accountants. Upon the occurrence of any event (the “Event”) that would give rise to any Payments pursuant to this Plan, the Company shall promptly request a determination in writing to be made within thirty (30) days of the date of the Event by independent public accountants (the “Accountants”) selected by the Company and reasonably acceptable to the Participant of the amount and type of such Payments which would produce the greatest after-tax benefit to the Participant. For the purposes of such determination, the Accountants may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and the Participant shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make their required determination. The Company shall bear all fees and expenses the Accountants may reasonably charge in connection with their services contemplated by this Section. Unless payment is required to commence earlier in order to comply with Section 409A of the Code, in the event that the report of the Accountants is not received within thirty (30) days following the Participant’s Termination Upon Change in Control, the Company shall pay to the Participant the cash severance benefits required by Section 5.2 above (subject to any reduction necessary to produce the greatest after-tax benefit to the Participant) within ten (10) days of the later of the date of the Accountants’ report of their determination or the payment date determined in accordance with Section 5.2(a) above.

7.1    Effect of Plan. The terms of this Plan, when accepted by a Participant pursuant to an executed Participation Agreement, shall supersede all prior arrangements, whether written or oral, and understandings regarding the subject matter of this Plan and shall be the exclusive agreement for the determination of any payments and benefits due to the Participant upon the events described in Sections 4, 4A, 5 and 6.

7.2    Noncumulation of Benefits. Except as expressly provided in a written agreement between a Participant and the Company entered into after the date of such Participant’s Participation Agreement and which expressly disclaims this Section 7.2 and is approved by the

Board or the Committee, the total amount of payments and benefits that may be received by the Participant as a result of the events described in Sections 4, 4A, 5 and 6 pursuant to (a) the Plan, (b) any agreement between the Participant and the Company or (c) any other plan, practice or statutory obligation of the Company, shall not exceed the amount of payments and benefits provided by this Plan upon such events (plus any payments and benefits provided pursuant a Prior Indemnity Agreement or an agreement evidencing an Equity Award, subject to such acceleration of vesting, exercisability and settlement provided by Section 4, 4A or Section 5.2 above, as applicable), and the aggregate amounts payable under this Plan shall be reduced to the extent of any excess (but not below zero).

The payments and benefits provided pursuant to this Plan (plus any payments and benefits provided pursuant a Prior Indemnity Agreement or an agreement evidencing an Equity Award, subject to such acceleration of vesting, exercisability and settlement provided by this Plan), if applicable, shall constitute the Participant’s sole and exclusive remedy for any alleged injury or other damages arising out of the cessation of the employment relationship between the Participant and the Company in the event of the Participant’s Termination Upon a Change in Control. The Participant shall be entitled to no other compensation, benefits, or other payments from the Company as a result of any Termination Upon a Change in Control with respect to which the payments and benefits described in this Plan (plus any payments and benefits provided pursuant a Prior Indemnity Agreement or an agreement evidencing an Equity Award, subject to such acceleration of vesting, exercisability and settlement provided by this Plan), if applicable, have been provided to the Participant, except as expressly set forth in this Plan or, subject to the provisions of Sections 7.2, in a duly executed employment agreement between Company and the Participant.

The Participant agrees to continue to abide by the terms and conditions of the confidentiality and/or proprietary rights agreement between the Participant and the Company or any other member of the Company Group.

If the Company performs its obligations to deliver the payments and benefits set forth in this Plan (plus any payments and benefits provided pursuant a Prior Indemnity Agreement or an agreement evidencing an Equity Award, subject to such acceleration of vesting, exercisability and settlement provided by this Plan), then, for a period equal to the greater of (a) one (1) year following the Participant’s Termination Upon a Change in Control, and (b) the Severance Benefit Period, the Participant shall not, directly or indirectly, recruit, solicit or invite the solicitation of any employees of the Company to terminate their employment relationship with the Company.

Neither the establishment of the Plan, nor any amendment thereto, nor the payment of any benefits shall be construed as giving any person the right to be retained by the Company, a Successor or any other member of the Company Group. Except as otherwise established in an employment agreement between the Company and a Participant, the employment relationship between the Participant and the Company is an “at-will” relationship. Accordingly, either the Participant or the Company may terminate the relationship at any time, with or without cause, and with or without notice except as otherwise provided by Section 15. In addition, nothing in this Plan shall in any manner obligate any Successor or other member of the Company Group to offer employment to any Participant or to continue the employment of any Participant which it does hire for any specific duration of time.

12.1    ERISA Plan. This Plan is intended to be (a) an employee welfare plan as defined in Section 3(1) of Employee Retirement Income Security Act of 1974 (“ERISA”) and (b) a “top-hat” plan maintained for the benefit of a select group of management or highly compensated employees of the Company Group. This document is intended to constitute both the Plan document and the Plan’s Summary Plan Description. For purposes of ERISA, the Company shall be “Plan Administrator.”

12.2    Application for Benefits. All applications for payments and/or benefits under the Plan (“Benefits”) shall be submitted to the Company’s Benefits department personnel (the “Claims Administrator”), with a copy to the Company’s General Counsel. Applications for Benefits must be in writing on forms acceptable to the Claims Administrator and must be signed by the Participant or beneficiary. The Claims Administrator reserves the right to require the Participant or beneficiary to furnish such other proof of the Participant’s expenses, including without limitation, receipts, canceled checks, bills, and invoices as may be required by the Claims Administrator.

(a)    If a claimant’s claim for Benefits is denied, the Claims Administrator shall provide notice to the claimant in writing of the denial within ninety (90) days after its submission. The notice shall be written in a manner calculated to be understood by the claimant and shall include:

(1)    The specific reason or reasons for the denial;

(2)    Specific references to the Plan provisions on which the denial is based;

(3)    A description of any additional material or information necessary for the applicant to perfect the claim and an explanation of why such material or information is necessary; and

(4)    An explanation of the Plan’s claims review procedures and a statement of claimant’s right to bring a civil action under ERISA Section 502(a) following an adverse benefit determination.

(b)    If special circumstances require an extension of time for processing the initial claim, a written notice of the extension and the reason therefor shall be furnished to the claimant before the end of the initial ninety (90) day period. In no event shall such extension exceed ninety (90) days.

(c)    If a claim for Benefits is denied, the claimant, at the claimant’s sole expense, may appeal the denial to the Committee (the “Appeals Administrator”) within sixty (60) days of the receipt of written notice of the denial. In pursuing such appeal the applicant or his duly authorized representative:

(1)    may request in writing that the Appeals Administrator review the denial;

(2)    may review pertinent documents; and

(d)    The decision on review shall be made within sixty (60) days of receipt of the request for review, unless special circumstances require an extension of time for processing, in which case a decision shall be rendered as soon as possible, but not later than one hundred twenty (120) days after receipt of the request for review. If such an extension of time is required, written notice of the extension shall be furnished to the claimant before the end of the original sixty (60) day period. The decision on review shall be made in writing, shall be written in a manner calculated to be understood by the claimant, and, if the decision on review is a denial of the claim for Benefits, shall include:

(1)    The specific reason or reasons for the denial;

(2)    Specific references to the Plan provisions on which the denial is based;

(3)    A description of any additional material or information necessary for the applicant to perfect the claim and an explanation of why such material or information is necessary; and

(4)    An explanation of the Plan’s claims review procedures and a statement of claimant’s right to bring a civil action under ERISA Section  502(a) following an adverse benefit determination.

13.1    Disputes Subject to Arbitration. Any claim, dispute or controversy arising out of this Plan, the interpretation, validity or enforceability of this Plan or the alleged breach thereof shall be submitted by the parties to binding arbitration by the American Arbitration Association or as otherwise required by ERISA; provided, however, that (a) the arbitrator shall have no authority to make any ruling or judgment that would confer any rights with respect to trade secrets, confidential and proprietary information or other intellectual property; and (b) this arbitration provision shall not preclude the parties from seeking legal and equitable relief from any court having jurisdiction with respect to any disputes or claims relating to or arising out of the misuse or misappropriation of intellectual property. Judgment may be entered on the award of the arbitrator in any court having jurisdiction.

13.2    Site of Arbitration. The site of the arbitration proceeding shall be in Santa Clara, California or any other site mutually agreed to by the Company and the Participant.

13.3    Costs and Expenses Borne by Company. All costs and expenses of arbitration, including but not limited to reasonable attorneys’ fees and other costs reasonably incurred by the Participant in connection with an arbitration in accordance with this Section 13, shall be paid by the Company. Notwithstanding the foregoing, if the Participant initiates the arbitration, and the arbitrator finds that the Participant’s claims were totally without merit or frivolous, then the Participant shall be responsible for the Participant’s own attorneys’ fees and costs.

14.1    Successors of the Company. The Company shall require any successor or assign (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company, expressly, absolutely and unconditionally to assume and agree to perform this Plan in the same manner and to the same extent that the Company would be required to perform it if no such succession or assignment had taken place. Failure of the Company to obtain such agreement shall be a material breach of this Plan and shall entitle the Participant to resign for Good Reason and to receive the benefits provided under this Plan in the event of Termination Upon a Change in Control.

14.2    Acknowledgment by Company. If, after a Change in Control, the Company fails to reasonably confirm that it has performed the obligation described in Section 14.1 within thirty (30) days after written notice from the Participant, such failure shall be a material breach of this Plan and shall entitle the Participant to resign for Good Reason and to receive the benefits provided under this Plan in the event of Termination Upon a Change in Control.

14.3    Heirs and Representatives of Participant. This Plan shall inure to the benefit of and be enforceable by the Participant’s personal or legal representatives, executors,

administrators, successors, heirs, distributees, devises, legatees or other beneficiaries. If the Participant should die while any amount would still be payable to the Participant hereunder (other than amounts which, by their terms, terminate upon the death of the Participant) if the Participant had continued to live, then all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Plan to the executors, personal representatives or administrators of the Participant’s estate.

15.    NOTICES

15.1    General. For purposes of this Plan, notices and all other communications shall be in writing and shall be deemed to have been duly given when personally delivered or when mailed by United States certified mail, return receipt requested, or by overnight courier, postage prepaid, as follows:

(b)    if to the Participant, at the home address which the Participant most recently communicated to the Company in writing.

15.2    Notice of Termination. Any termination by the Company of the Participant’s employment during the Change in Control Period or any resignation by the Participant during the Change in Control Period shall be communicated by a notice of termination or resignation to the other party hereto given in accordance with Section 15.1. Such notice shall indicate the specific termination provision in this Plan relied upon, shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination under the provision so indicated, and shall specify the termination date.

The Plan and/or any Participation Agreement executed by a Participant may not be terminated with respect to such Participant without the written consent of the Participant and the approval of the Board or the Committee. The Plan and/or any Participation Agreement executed by a Participant may be modified, amended or superseded with respect to such Participant only by a supplemental written agreement between the Participant and the Company approved by the Board or the Committee. Notwithstanding any other provision of the Plan to the contrary, the Board or the Committee may, in its sole and absolute discretion and without the consent of any Participant, amend the Plan or any Participation Agreement, to take effect retroactively or otherwise, as it deems

necessary or advisable for the purpose of conforming the Plan or such Participation Agreement to any present or future law relating to plans of this or similar nature (including, but not limited to, Section 409A of the Code), and to the administrative regulations and rulings promulgated thereunder.

17.1    Unfunded Obligation. Any amounts payable to Participants pursuant to the Plan are unfunded obligations. The Company shall not be required to segregate any monies from its general funds, or to create any trusts, or establish any special accounts with respect to such obligations. The Company shall retain at all times beneficial ownership of any investments, including trust investments, which the Company may make to fulfill its payment obligations hereunder. Any investments or the creation or maintenance of any trust or any Participant account shall not create or constitute a trust or fiduciary relationship between the Board or the Company and a Participant, or otherwise create any vested or beneficial interest in any Participant or the Participant’s creditors in any assets of the Company.

17.2    No Duty to Mitigate; Obligations of Company. A Participant shall not be required to mitigate the amount of any payment or benefit contemplated by this Plan by seeking employment with a new employer or otherwise, nor shall any such payment or benefit (except for benefits to the extent described in Section 6.2) be reduced by any compensation or benefits that the Participant may receive from employment by another employer. Except as otherwise provided by this Plan, the obligations of the Company to make payments to the Participant and to make the arrangements provided for herein are absolute and unconditional and may not be reduced by any circumstances, including without limitation any set-off, counterclaim, recoupment, defense or other right which the Company may have against the Participant or any third party at any time.

17.3    No Representations. By executing a Participation Agreement, the Participant acknowledges that in becoming a Participant in the Plan, the Participant is not relying and has not relied on any promise, representation or statement made by or on behalf of the Company which is not set forth in this Plan.

17.4    Waiver. No waiver by the Participant or the Company of any breach of, or of any lack of compliance with, any condition or provision of this Plan by the other party shall be considered a waiver of any other condition or provision or of the same condition or provision at another time.

17.5    Choice of Law. The validity, interpretation, construction and performance of this Plan shall be governed by the substantive laws of the State of California, without regard to its conflict of law provisions to the extent that ERISA does not govern.

17.6    Validity. The invalidity or unenforceability of any provision of this Plan shall not affect the validity or enforceability of any other provision of this Plan, which shall remain in full force and effect.

17.7    Benefits Not Assignable. Except as otherwise provided herein or by law, no right or interest of any Participant under the Plan shall be assignable or transferable, in whole or in part, either directly or by operation of law or otherwise, including, without limitation, by execution, levy, garnishment, attachment, pledge or in any other manner, and no attempted transfer or assignment thereof shall be effective. No right or interest of any Participant under the Plan shall be liable for, or subject to, any obligation or liability of such Participant.

17.8    Tax Withholding. All payments made pursuant to this Plan will be subject to withholding of applicable income and employment taxes.

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

By executing a Participation Agreement, the Participant acknowledges that the Participant has received a copy of this Plan and has read, understands and is familiar with the terms and provisions of this Plan. This Plan shall constitute an agreement between the Company and the Participant executing a Participation Agreement.

For this purpose, annual incentive bonuses shall not include signing bonuses or other nonrecurring cash incentive awards.

(1)    any “person” (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), other than a trustee or other fiduciary holding securities of the Company under an employee benefit plan of the Company, becomes the “beneficial owner” (as defined in Rule 13d‑3 promulgated under the Exchange Act), directly or indirectly, of securities of the Company representing more than fifty percent (50%) of the total combined voting power of the Company’s then‑outstanding securities entitled to vote generally in the election of directors;
