termination; (ii) unreimbursed business expenses required to be reimbursed to the Participant in accordance with the Company’s business expense reimbursement policy, and (iii) pay for accrued but unused vacation that the Company is
legally obligated to pay the Participant. In addition, if the termination is by the Company other than for Cause or if the Participant resigns for Good Reason, the Participant shall be entitled to the amounts and benefits specified below.

 (b) Termination by the Company Without Cause or the Participant Terminates for Good Reason. If the
Participant’s employment is terminated by the Company without Cause or if the Participant resigns for Good Reason, and such termination is not during the Change of Control Period, then, subject to Sections 3(a) and 5, the Participant shall

policies; (ii) the Participant’s Prorated Annual Incentive, and (iii) accelerated vesting with respect to the Participant’s then outstanding unvested equity awards with the Participant to receive additional vesting credit to be

 (c) Termination Without Cause or Resignation for Good Reason During the Change of Control Period. If the Participant’s
employment is terminated by the Company without Cause or by the Participant for Good Reason, and the termination is within the Change in Control Period, then, subject to Sections 3(a) and 5, Participant shall receive: (i) an amount equal
to the Participant’s Severance Multiple multiplied by the sum of the Participant’s Base Salary and Average Annual Incentive, payable in equal installments over the Severance Period and in accordance with the Company’s normal payroll
policies; (ii) the Participant’s Prorated Annual Incentive; (iii) 100% accelerated vesting with respect to the Participant’s then outstanding unvested equity awards, (iv) any New Option/SAR shall have an extended

 (d) Certain Terminations Prior to a Change of Control. If a Change in Control
occurs, and if the Participant’s employment is terminated within six (6) months prior to the Change in Control and the Participant can prove to the Committee’s satisfaction (as determined by the Committee in its sole discretion) that
such termination arose in connection with or anticipation of a Change in Control, then for purposes of the Plan, such termination shall be deemed to have occurred during the Change in Control Period. 
 (e) Golden Parachute Excise Taxes. 
 (i) Parachute Payments of Less than 3x Base Amount Plus Fifty Thousand Dollars. In the event that the benefits provided for in this agreement or otherwise payable to Participant (a) constitute
“parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), (b) would be subject to the excise tax imposed by Section 4999 of the Code, and (c) the
aggregate value of such parachute payments, as determined in accordance with Section 280G of the Code and the proposed Treasury Regulations thereunder (or the final Treasury Regulations, if they have then been adopted) is less than the product
obtained by multiplying three by Participant’s “base amount” within the meaning of Code Section 280G(b)(3) and adding to such product fifty thousand dollars, then such benefits shall be reduced to the extent necessary (but only
to that extent) so that no portion of such benefits will be subject to excise tax under Section 4999 of the Code. 
 (ii)
Parachute Payments Equal to or Greater than 3x Base Amount Plus Fifty Thousand Dollars. In the event that the benefits provided for in this agreement or otherwise payable to Participant (a) constitute “parachute payments”
within the meaning of Section 280G of the Code, (b) would be subject to the excise tax imposed by Section 4999 of the Code, and (c) the aggregate value of such parachute payments, as determined in accordance with
Section 280G of the Code and the proposed Treasury Regulations thereunder (or the final Treasury Regulations, if they have then been adopted) is equal to or greater than the product obtained by multiplying three by Participant’s “base
amount” within the meaning of Code Section 280G(b)(3) and adding to such product fifty thousand dollars, then (A) the benefits shall be delivered in full, and (B) the Participant shall receive (1) a payment from the Company
sufficient to pay such excise tax and (2) an additional payment from the Company sufficient to pay the federal and state income and employment taxes and additional excise taxes arising from the payments made to the Participant by the Company
pursuant to this clause (B). 
 (iii) 280G Determinations. Unless the Company and the Participant otherwise agree in
writing, the determination of Participant’s excise tax liability and the amount required to be paid or reduced under this Section 4(e) shall be made in writing by the Company’s independent auditors who are primarily used by the
Company immediately prior to the Change of Control (the “Accountants”). For purposes of making the calculations required by this Section 4(e), the Accountants 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. The Company and the Participant shall furnish to the Accountants such information and documents as the Accountants may reasonably
request in order to make a determination under this Section. The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this Section 5. 
 (f) Internal Revenue Code Section 409A. Notwithstanding any other provision of this Plan, if the Participant is a “key
employee” under Code Section 409A and a delay in making any payment or providing any benefit under this Plan is required by Code Section 409A, such payments shall not be made until the end of six (6) months following the date of
the Participant’s separation from service as required by Code Section 409A. 
 (g) Mitigation Required.
Payments and benefits provided for under the Plan shall be reduced by any compensation or benefits earned by the Participant as a result of any earnings or benefits that the Participant may receive from any other source following his or her
termination of employment. Moreover, payments and benefits provided for under the Plan shall be reduced by any payments or benefits received by Participant pursuant to any other plan, policy, agreement or arrangement with the Company. 
 5. Covenants not to Compete and not to Solicit. 
 (a) Remedies for Breach. The Company’s obligations to provide Severance Payments as provided in Section 4 are expressly conditioned upon the Participant’s covenants not to compete and not to
solicit as provided herein. In the event the Participant breaches his or her obligations to the Company as provided herein, the Company’s obligations to make Severance Payments to the Participant pursuant to Section 4 shall cease, without
prejudice to any other remedies that may be available to the Company. 
 (b) Covenant Not to Compete. If a Participant
is receiving Severance Payments pursuant to 4 hereof, then for the duration of the Severance Period, the Participant shall not directly engage in (whether as an employee, consultant, proprietor, partner, director or otherwise), or have any ownership
interest in, or participate in the financing, operation, management or control of, any person, firm, corporation or business that engages or participates anywhere in the world in providing goods and services similar to those provided by the Company
upon the date of the Participant’s termination of employment. Ownership of less than 3% of the outstanding voting stock of a publicly-held corporation or other entity shall not constitute a violation of this provision. 
 (c) Covenant Not to Solicit. If a Participant is receiving Severance Payments pursuant to Section 4 hereof, he or she
shall not, at any time during the Severance Period, directly or indirectly solicit any individuals to leave the Company’s employ for any reason or interfere in any other manner with the employment relationships at the time existing between the
Company and its current or prospective employees. 
 (d) Representations. The covenants contained in this
Section 5 shall be construed as a series of separate covenants, one for each county, city and state (or analogous entity) and country of the world. If, in any judicial proceeding, a court shall refuse to enforce any of the separate covenants,
or any part thereof, then such unenforceable covenant, or such part thereof, shall be deemed eliminated from this Plan for the purpose of those proceedings to the extent necessary to permit the remaining separate covenants, or portions thereof, to
be enforced. 







 (e) Reformation. In the event that the provisions of this Section 5 should ever be
deemed to exceed the time or geographic limitations, or scope of this covenant, permitted by applicable law, then such provisions shall be reformed to the maximum time or geographic limitations, as the case may be, permitted by applicable laws.

 6. Employment Status; Withholding 
 (a) Employment Status. This Plan does not constitute a contract of employment or impose on the Participant or the Company any obligation to retain the Participant as an Employee, to change the status of the
Participant’s employment, or to change the Company’s policies regarding termination of employment. The Participant’s employment is and shall continue to be at-will, as defined under applicable law. If the Participant’s employment
with the Company or a successor entity terminates for any reason, the Participant shall not be entitled to any payments, benefits, damages, awards or compensation other than as provided by this Plan or available in accordance with the Company’s
established employee plans and practices or other agreements with the Company at the time of termination. 
 (b) Taxation
of Plan Payments. All amounts paid pursuant to this Plan shall be subject to all applicable payroll and withholding taxes. 
 7.
Arbitration. Any dispute or controversy that shall arise out of the terms and conditions of the Plan and that cannot be resolved within thirty (30) days of the dispute or controversy through good-faith negotiation or non-binding
mediation between the Participant and the Company, shall be subject to binding arbitration in Santa Clara, California before the American Arbitration Association under its National Rules for the Resolution of Employment Disputes, supplemented by the
California Rules of Civil Procedure. The prevailing party in any arbitration shall be entitled to injunctive relief in any court of competent jurisdiction to enforce the arbitration award. 
 8. Successors to Company and Participants. 
 (a) Company’s Successors. Any successor to the Company (whether direct or indirect and whether by purchase, lease, merger, consolidation, liquidation or otherwise) to all or substantially all of the
Company’s business and/or assets shall assume the obligations under this Plan and agree expressly to perform the obligations under this Plan by executing a written agreement. For all purposes under this Plan, the term “Company” shall
include any successor to the Company’s business and/or assets which executes and delivers the assumption agreement described in this subsection or which becomes bound by the terms of this Plan by operation of law. 
 (b) Participant’s Successors. All rights of the Participant hereunder shall inure to the benefit of, and be enforceable by,
the Participant’s personal or legal representatives, executors, administrators, successors, heirs, devisees and legatees. 







 9. Duration, Amendment and Termination 
 (a) Duration. The initial term of this Plan shall be three (3) years from the Effective Date. At the end of the initial three
(3) year term and any subsequent annual terms, the Plan shall be automatically extended for a one (1) year period unless terminated by the Committee prior to the end of such term, provided that any such termination shall be effective only
with respect to future Plan Years. Participants shall be given notice of a Plan termination within sixty (60) days of the Board’s decision. A termination of this Plan pursuant to the preceding sentence shall be effective for all purposes,
except that such termination shall not affect the right of a Participant whose employment termination date occurred prior to the termination date of the Plan to receive any Severance Payment to which such Participant is then entitled under the terms
of the Plan. 
 (b) Change in Control. In the event of a Change in Control during the term of the Plan, the term of the
Plan shall be the Change in Control Period. 
 (c) Amendment and Termination. The Committee, shall have the
discretionary authority to amend the Plan at any time, except no such amendment or termination shall affect the right of a Participant whose employment termination date occurred prior to the termination date of the Plan to receive any Severance
Payment to which such Participant is then entitled under the terms of the Plan without the written consent of the Participant.

voluntary or involuntary assignment or by operation of law, including (without limitation) bankruptcy, garnishment, attachment or other creditor’s process, and any action in violation of this subsection shall be void. However, payments and
benefits under the Plan may be reduced or offset by any amount a Participant may owe the Company, to the extent permitted by applicable law. 







 (d) Company may assign its rights under this Plan to an affiliate, and an affiliate may
assign its rights under this Plan to another affiliate of the Company or to the Company; provided, however, that no assignment shall be made if the net worth of the assignee is less than the net worth of the Company at the time of assignment;
