	2.	SEVERANCE PAYMENT; BENEFITS. 

  

	 	a.	 Each Eligible Employee who incurs a Termination shall be entitled, subject to the timely execution, return and non-revocation of the Severance
Agreement and Release, to receive from the Company, subject to the conditions set forth in Sections 2(d), 2(g) and 4(b), a cash payment equal to the sum of (i) such Eligible Employee’s annual base salary as in effect immediately prior to
the Severance Date, plus (ii) such Eligible Employee’s target annual bonus or cash incentive opportunity for the year in which the Severance Date occurs. For purposes of clauses (i) and (ii) above, annual base salary and target
annual bonus or cash incentive opportunity shall be the amount in effect immediately prior to the Severance Date without regard to any reductions therein which constitute Good Reason. The Severance Payment shall be paid to a Severed Employee in a




  
 4 









	 	
cash lump sum within sixty (60) days of the Severance Date, provided that the Severed Employee signs and can no longer revoke the Severance Agreement and Release during that sixty
(60) day period. 

  

	 	b.	Subject to the conditions set forth in Sections 2(d), 2(g) and 4(b), and to the extent not vested and exercised or paid out in connection with the Change in Control, in
the event an Eligible Employee incurs a Termination, on the Severance Date, the Severed Employee shall become fully vested in all outstanding Equity Awards, including without limitation stock options, restricted stock, restricted stock units, and
stock appreciation rights (notwithstanding any provision of the Company’s applicable equity plans to the contrary). Notwithstanding the foregoing, in the event of a Termination within three (3) months preceding a Change in Control, the
Severed Employee shall not forfeit or further vest in any unvested Equity Awards between the Severance Date and the date of the Change in Control, but all such awards shall vest in full upon the Change in Control 


 

	 	i.	In the case of an Equity Award consisting of a stock option or stock appreciation right, such stock option or stock appreciation right shall continue to be exercisable
for a period of twelve (12) months from the Severance Date (or such longer period as may be prescribed in the plan or agreement governing such option), but in no event later than the expiration date of such option or stock appreciation right.


  

	 	ii.	In the case of an Equity Award consisting of restricted stock, the Company shall remove any restrictions (other than restrictions required by Federal securities law) or
conditions in respect of the restricted stock vested on or before the later of the Severance Date and the Change in Control. 

  

	 	iii.	 In the case of an Equity Award consisting of restricted stock units, the Company shall remove any restrictions (other than restrictions required by
Federal securities law) or conditions in respect of the restricted stock units vested on or before the later of the Severance Date and the Change in Control, but any such restricted stock unit shall be settled in accordance with its terms, and in no
event shall such settlement occur later than two and one-half (2  1/2) months after the end of the calendar year in which the Termination occurs. 


  

	 	c.	 Subject to the conditions set forth in Sections 2(d), 2(g) and 4(b), in the event an Eligible Employee incurs a Termination, and provided that the
Eligible Employee timely elects continued coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”), the Company shall reimburse the Eligible Employee for the COBRA premiums of such Eligible
Employee’s group medical, dental and vision coverage (including coverage for the Eligible Employee’s eligible dependents who were covered as of the Severance Date), commencing on the date immediately following such Eligible Employee’s
Severance Date and continuing for the period set forth in the last sentence of this Section 2(c) (the “Continuation Period”). Such COBRA premium payments shall continue for the duration of the Continuation Period;
provided, however, that no such COBRA premium payments shall be made following an event which terminates the Eligible Employee’s continuation coverage under COBRA, including, but not limited to, the Eligible Employee’s coverage by a
medical, dental or vision insurance plan of a subsequent employer. Each Eligible Employee shall be required to notify the Company immediately if the Eligible Employee becomes covered by a medical, dental or vision insurance plan of a subsequent
employer or otherwise becomes ineligible for COBRA continuation coverage. The Employer will provide benefits under this Section 2(c) for twelve (12) months from the Severance Date. Notwithstanding the above, if the Company determines in
its sole discretion that it cannot provide the foregoing COBRA benefits without potentially violating 



  
 5 









	 	
applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company shall in lieu thereof provide to the Eligible Employee a taxable monthly payment
(which shall not be grossed up for applicable income and employment taxes) in an amount equal to the monthly COBRA premium that the Eligible Employee would be required to pay to continue group health coverage in effect on the date of Termination,
which payments shall be made regardless of whether the Eligible Employee elects COBRA continuation coverage and such payment shall end on the earlier of (x) an event that terminates the Eligible Employee’s continuation coverage under COBRA
(including, but not limited to, the Eligible Employee’s coverage by a medical, dental or vision insurance plan of a subsequent employer) and (y) the last day of the twelfth calendar month following the Severance Date.


 At the conclusion of the Continuation Period, the Eligible Employee shall be responsible for the entire payment
of premiums required under COBRA for the duration of the COBRA continuation period. For purposes of this Section 2(c), applicable premiums that will be paid by the Company during the Continuation Period shall not include any amounts payable by
the Eligible Employee under a Section 125 health care reimbursement plan, which amounts, if any, are the sole responsibility of the Eligible Employee. 
  

	 	d.	No Severed Employee shall be eligible to receive a Severance Payment or other benefits under the Plan unless he or she first timely executes, returns to the Company and
does not revoke the Severance Agreement and Release in accordance with the requirements of Section 3(d). 

  

	 	e.	An Employer shall be entitled to withhold from amounts paid to the Severed Employee hereunder any U.S. or foreign federal, state or local withholding or other taxes or
charges which it is from time to time reasonably believes it is required to withhold. 

  

	 	f.	A Severed Employee shall not be required to mitigate the amount of any payment provided for in this Plan by seeking other employment or otherwise, nor, except as
otherwise provided in Section 2(c), shall the amount of any payment or benefit provided for in this Plan be reduced by any compensation earned by such a Severed Employee as a result of employment by another employer after the Severance Date or
otherwise. 

  

	 	g.	 In the event that the benefits provided for in this Plan or otherwise payable to the Eligible Employee (i) constitute “parachute
payments” within the meaning of Section 280G of the Code and (ii) but for this Section 2(g), would be subject to the excise tax imposed by Section 4999 of the Code, then the Eligible Employee’s benefits under this Plan
shall be payable either (i) in full, or (ii) as to such lesser amount which would result in no portion of such benefits being subject to the excise tax under Section 4999 of the Code, whichever of the foregoing amounts, taking into
account the applicable federal, state and local income taxes and the excise tax imposed by Section 4999, results in the receipt by the Eligible Employee on an after-tax basis, of the greatest amount of benefits Agreement,
notwithstanding that all or some portion of such benefits may be taxable under Section 4999 of the Code. Any reduction shall be made in the following manner: first a pro rata reduction of (i) cash payments subject to
Section 409A of the Code as deferred compensation and (ii) cash payments not subject to Section 409A of the Code, and second a pro rata cancellation of (i) equity-based compensation subject to Section 409A of the Code as
deferred compensation and (ii) equity-based compensation not subject to Section 409A of the Code. Reduction in either cash payments or equity compensation benefits shall be made pro rata between and among benefits which are subject to
Section 409A of the Code and benefits which are exempt from Section 409A of the Code. Unless the Company and the Eligible Employee otherwise agree in writing, all determinations required to be made under this Section 2(g), including
the manner and amount of any reduction in the Eligible Employee’s benefits under this 



  
 6 









	 	
Section 2(g), and the assumptions to be used in arriving at such determinations, shall be made in writing in good faith by an accounting firm reasonably selected by the Company (the
“Accountants”). For the purposes of making the calculations required under this Section 2(g), the Accountants may make reasonable assumptions and approximations concerning the application of Sections 280G and 4999 of the
Code. The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this Section 2(g). 

  

	3.	PLAN ADMINISTRATION. 

  

	 	a.	The Plan Administrator shall administer the Plan and shall have the full, discretionary authority to (i) construe and interpret the Plan, (ii) adopt
amendments to the Plan which are deemed necessary or desirable to bring the Plan in compliance with all applicable laws and regulations, including without limitation Section 409A of the Code and the regulations thereunder, (iii) prescribe,
amend and rescind rules and regulations necessary or desirable for the proper and effective administration of this Plan, (iv) prescribe, amend, modify and waive the various forms and documents to be used in connection with the operation of this
Plan and also the times for giving any notice required by this Plan, (v) settle and determine any controversies and disputes as to rights and benefits under this Plan, (vi) decide any questions of fact arising under this Plan and
(vii) make all other determinations necessary or advisable for the administration of this Plan, subject to all of the provisions of this Plan. 

  

	 	b.	The Plan Administrator may delegate any of its duties hereunder to such person or persons from time to time as it may designate. 


 

	 	c.	The Plan Administrator is empowered, on behalf of this Plan, to engage accountants, legal counsel and such other personnel as it deems necessary or advisable to assist
it in the performance of its duties under this Plan. The functions of any such persons engaged by the Plan Administrator shall be limited to the specified services and duties for which they are engaged, and such persons shall have no other duties,
obligations or responsibilities under this Plan. Such persons shall exercise no discretionary authority or discretionary control respecting the management of this Plan. All reasonable expenses thereof shall be borne by the Employer.


  

	 	d.	The Plan Administrator shall promptly provide the Severance Agreement and Release to an Eligible Employee who becomes eligible for a payment and benefits under
Section 2 and shall require an executed Severance Agreement and Release to be returned to the Company within no more than forty-five (45) days (or such shorter time period as the Plan Administrator may impose, subject to compliance with
applicable law) from the date the Eligible Employee receives the Severance Agreement and Release. If the Eligible Employee does not execute and return the Severance Agreement and Release to the Plan Administrator within the specified time period, he
or she will not be entitled to any payments or benefits under this Plan. Any deadline established by the Plan Administrator shall ensure that the payment of any benefit under Section 2 is made no more than two and one-half months after the end
of the calendar year in which the Termination occurs. 

  

	4.	PLAN TERMINATION AND MODIFICATION. 

  

	 	a.	This Plan may not be terminated, except that this Plan shall terminate automatically one year and one day after a Change in Control or, if later, when all benefits
payable under this Plan are paid. 

  

	 	b.	 To the extent (a) any payments or benefits to which Eligible Employee becomes entitled under this Plan, or under any agreement or plan referenced
herein, in connection with Employee’s 



  
 7 









	 	
Termination constitute deferred compensation subject to Section 409A of the Code and (b) the Eligible Employee is deemed at the time of such termination of employment to be a
“specified employee” under Section 409A of the Code, then such payments shall not be made or commence until the earliest of (i) the expiration of the six (6) month period measured from the date of Employee’s
“separation from service” (as such term is at the time defined in Treasury Regulations under Section 409A of the Code) from the Company; or (ii) the date of the Eligible Employee’s death following such separation from
service; provided, however, that such deferral shall be effected only to the extent required to avoid adverse tax treatment to the Eligible Employee, including without limitation the additional twenty percent (20%) tax for which the Eligible
Employee would otherwise be liable under Section 409A(a)(1)(B) of the Code in the absence of such deferral. Upon the expiration of the applicable deferral period, any payments which would have otherwise been made during that period (whether in
a single sum or in installments) in the absence of this paragraph shall be paid to the Eligible Employee or the Eligible Employee’s beneficiary in one lump sum (without interest). Any termination of the Eligible Employee’s employment is
intended to constitute a “separation from service” as such term is defined in Treasury Regulation Section 1.409A-1. It is intended that each installment of the payments provided hereunder, if any, constitute separate
“payments” for purposes of Treasury Regulation Section 1.409A-2(b)(2)(i). It is further intended that payments hereunder satisfy, to the greatest extent possible, the exemption from the application of Section 409A of the Code
(and any state law of similar effect) provided under Treasury Regulation Section 1.409A-1(b)(4) (as a “short-term deferral”). 


 

	5.	GENERAL PROVISIONS. 

  

	 	a.	Except as otherwise provided herein or by law, no right or interest of any Eligible Employee under this 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 manner; no attempted assignment or transfer thereof shall be effective; and no right or interest of any
Eligible Employee under this Plan shall be liable for, or subject to, any obligation or liability of such Eligible Employee. 

  

	 	b.	This Plan shall inure to the benefit of and be binding upon the heirs, executors, administrators, successors and assigns of the parties, including without limitation
each Eligible Employee, present and future, and any successor to the Employer. If a Severed Employee shall die while any amount would still be payable to such Severed Employee under this Plan if the Severed Employee had continued to live, all such
amounts, shall be paid in accordance with the terms of this Plan to the executor, personal representative or administrators of the Severed Employee’s estate. If a Severed Employee is unable to care for his or her affairs while any amount is
payable to such Severed Employee under this Plan, payment may be made directly to his or her legal guardian or personal representative. 

  

	 	c.	If an Employer is obligated by law, contract, policy or otherwise to pay severance, a termination indemnity, notice pay, or the like, or if an Employer is obligated by
law to provide advance notice of separation (“Notice Period”), then any Severance Payment hereunder shall be reduced by the amount of any such severance pay, termination indemnity, notice pay or the like, as applicable, and
by the amount of any compensation received during any Notice Period. 

  

	 	d.	Neither the establishment of this Plan, nor any modification thereof, nor the creation of any fund, trust or account, nor the payment of any benefits shall be construed
as giving any Eligible Employee, or any person whomsoever, the right to be retained in the service of the Employer, and all Eligible Employees shall remain subject to discharge to the same extent as if this Plan had never been adopted.



  
 8 









	 	e.	If any provision of this Plan shall be held invalid or unenforceable, such invalidity or unenforceability shall not affect any other provisions hereof, and this Plan
shall be construed and enforced as if such provisions had not been included. 

  

	 	f.	The headings and captions herein are provided for reference and convenience only, shall not be considered part of this Plan, and shall not be employed in the
construction of this Plan. 

  

	 	g.	This Plan shall not be funded. No Eligible Employee shall have any right to, or interest in, any assets of any Employer which may be applied by the Employer to the
payment of benefits or other rights under this Plan. 

  

	 	h.	Any notice or other communication required or permitted pursuant to the terms hereof shall be in writing and shall be given when delivered or mailed by registered or
certified mail, return receipt requested, postage prepaid, addressed to the intended recipient at his, her or its last known address. A written notice of an Eligible Employee’s Severance Date by the Company or the Eligible Employee, as the case
may be, to the other shall (i) indicate the specific termination provision of this Plan that is being relied upon; (ii) to the extent applicable, set forth in reasonable detail the facts and circumstances claimed to provide a basis for
termination of the Eligible Employee’s employment under the provision so indicated; and (iii) specify the termination date (which date, in the case of a termination by the Eligible Employee for Good Reason, shall be not less than thirty
(30), and in all other cases shall be not less than fifteen (15) days nor more than sixty (60) days after the giving of such notice). The failure by the Company or the Eligible Employee to provide such notice or to set forth in such notice
any fact or circumstance which contributes to a showing of Good Reason or Cause shall not waive any right of the Company or the Eligible Employee hereunder or preclude the Company or Eligible Employee from asserting such fact or circumstance in
enforcing the Company’s or the Eligible Employee’s rights hereunder. 

  

	 	i.	Nothing in this Plan shall require the Employer to provide any payment that duplicates any payment, benefit, or grant that an Eligible Employee is entitled to receive
under any Employer compensation or benefit plan, award agreement, or other arrangement (including any offer letter or employment agreement). Any severance benefit provided under any Employer compensation or benefit plan, award agreement, or other
arrangement (including any offer letter or employment agreement), including without limitation any severance plans or policies, shall offset, on a dollar for dollar basis, any benefits owed under this Plan. This Plan shall supersede and replace any
benefits, including equity acceleration and severance payments (both single trigger and double trigger) an Eligible Employee may otherwise be entitled to upon a Change in Control of the Company pursuant to any other Employer compensation or benefit
plan, award agreement or other arrangement (including any offer letter or employment agreement). 

  

	 	j.	Except to the extent explicitly provided in this Plan, any awards made under any Employer compensation or benefit plan or program shall be governed by the terms of that
plan or program and any applicable award agreement thereunder as in effect from time to time. The amounts paid or provided under this Plan shall not be treated as compensation for purposes of determining any benefits payable under any Employer
retirement, life insurance, or other employee benefit plan. 


  
 9 









	 	k.	This Plan shall be construed and enforced according to the laws of the State of California (not including any California law that would require the substantive law of
another jurisdiction to apply).

This Severance Agreement and Release (this “Agreement”) is made as of

“Employer”), and [            ], an individual residing (“Employee”). 
 A. Employee has been employed by Employer, and Employee has entered into the Company’s Proprietary Information and Inventions Agreement (the “Proprietary Information

benefits and obligations of the parties arising out of Employee’s employment by Employer and the severance of such employment in connection with a Change in Control as determined in accordance with the Plan. 

C. Employee recognizes that this Agreement will automatically be revoked and Employee shall forfeit any benefit to which he or she may be entitled under
the Plan unless Employee submits an executed copy of this Agreement or similar agreement to be provided to persons employed by the Company outside the United States to the Employer on or before

 NOW, THEREFORE, in consideration of the mutual
promises and covenants set forth below, and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Employer and Employee agree as follows:

will be less all applicable deductions (including without limitation any federal, state or local tax withholdings). Such payment and benefits are contingent upon the execution of this Agreement by Employee and Employee’s compliance with all
terms and conditions of this Agreement and the Plan. Employee agrees that if this Agreement does not become effective, Employer shall not be required to make any further payments or provide any further benefits to Employee pursuant to this Agreement
or the Plan and shall be entitled to recover all payments and be reimbursed for all benefits already made or provided by it (including interest thereon). Except for Employee’s final paycheck and the amounts and benefits set forth herein and in

be owed. 

  

	 	3.	 Release of Employer. In consideration of the obligations of Employer described in Paragraph 2 above, Employee hereby completely releases
and forever discharges Employer, its related corporations, divisions and entities, its predecessors, successors, and assigns, and its and each of their officers, directors, employees and agents, (collectively referred to as the
“Releasees”) from all claims, rights, demands, actions, liabilities and causes of action of any kind whatsoever, known and unknown, which Employee may have or have ever had against the Releasees











	 	
(“claims”) including without limitation all claims arising from or connected with Employee’s employment by the Employer, whether based in tort or contract (express or
implied) or on federal, state or local law or regulation. Employee has been advised that Employee’s release does not apply to any rights or claims that may arise after the date that this Agreement is signed by the Employee (the
“Effective Date”). This Agreement shall not affect Employee’s rights under the Older Workers Benefit Protection Act to have a judicial determination of the validity of the release contained herein. The release of claims
set forth in this Agreement shall not include any release of any rights of indemnification that Employee may have in his capacity as an officer of the Company, which may be provided pursuant to the Company’s certificate of incorporation or its
bylaws or pursuant to any indemnification agreement entered into by Employee and Employer. 

  

	 	4.	Acknowledgment. Employee understands and agrees that this is a final release and that Employee is waiving all rights now or in the future to pursue any remedies
available under any employment related cause of action against the Releasees, including without limitation claims of wrongful discharge, emotional distress, defamation, harassment, discrimination, retaliation, breach of contract or covenant of good
faith and fair dealing, claims of violation of the California Labor Code and claims under Title VII of the Civil Rights Act of 1964, as amended, the Equal Pay Act of 1963, the Civil Rights Act of 1866, as amended, the Americans with Disabilities
Act, the Age Discrimination in Employment Act (the “ADEA”), the Family and Medical Leave Act, the California Family Rights Act, the California Fair Employment and Housing Act, the Employee Retirement Income Security Act, and
any other laws and regulations relating to employment. Employee further acknowledges and agrees that Employee has received all leave to which Employee is entitled under all federal, state, and local laws and regulations related to leave from
employment, including, but not limited to, the Family and Medical Leave Act, the California Family Rights Act, and California worker’s compensation laws. 


 

	 	5.	Waiver of California Civil Code. Employee hereby expressly waives the provision of California Civil Code Section 1542 which provides as follows:


 A general release does not extend to claims which the creditor does not know or suspect to exist in his/her
favor at the time of executing the release, which if known by him/her must have materially affected his/her settlement with the debtor. 
 Employee acknowledges that the waiver of this Section of the California Civil Code set forth above is an essential and material term of this release, and that Employee has read this provision, and intends
these consequences even as to unknown claims which may exist at the time of this release. 
  

	 	6.	 Covenant Not to Sue. Employee represents that Employee has not filed or commenced any proceeding against the Releasees and agrees that at no
time in the future will Employee file or maintain any charge, claim or action of any kind, nature and character whatsoever against the Releasees, or cause or knowingly permit any such charge, claim or action to be filed or maintained, in any
federal, state or municipal court, administrative agency or other tribunal, arising out of any of the matters covered by Paragraph 3 above, except as provided in the following sentence. Notwithstanding Employee’s release and waiver of remedies
under the ADEA, this Agreement and the above covenant not to sue do not affect enforcement of the ADEA by the Equal Employment Opportunity Commission (“EEOC”), nor preclude Employee from (a) filing an ADEA charge with
the EEOC, (b) participating in an ADEA investigation or proceeding conducted by the EEOC, or (c) initiating a proceeding regarding the enforceability of this Agreement with respect to ADEA rights and remedies. If Employee initiates any
lawsuit or other legal proceeding in contravention of this covenant not to sue (other than a proceeding 



  
 2 








 
regarding the enforceability of this Agreement with respect to ADEA rights and remedies), Employee shall be required to immediately repay to Employer the full consideration paid to Employee
pursuant to Paragraph 2 above, regardless of the outcome of Employee’s legal action. 
  

	 	7.	Return of Property; Confidentiality; Inventions.  

  

	 	a.	Employee represents that Employee does not have in Employee’s possession any records, documents, specifications, or any confidential material or any equipment or
other property of Employer. 

  

	 	b.	Employee represents that Employee has complied with and will continue to comply with the terms and conditions of the Proprietary Information Agreement.


  

	 	8.	Non-Disparagement. Without limiting the foregoing, Employee agrees that Employee will not make statements or representations to any other person, entity or firm
which may cast Employer, or its directors, officers, agents or employees, in an unfavorable light, which are offensive, or which could adversely affect Employer’s name or reputation or the name or reputation of any director, officer, agent or
employee of Employer. The parties agree that the provisions of this Paragraph 8 are material terms of this Agreement. 

  

	 	9.	Cooperation with Employer. Employee agrees that Employee will cooperate with Employer, its agents, and its attorneys with respect to any matters in which
Employee was involved during Employee’s employment with Employer, will provide upon request from Employer all such information or information about any such matter, and will be available to reasonably assist with any litigation or potential
litigation relating to Employee’s actions as an employee of Employer. 

  

	 	10.	Non-Solicitation. For a period of one (1) year after Employee’s Termination, Employee agrees that Employee will not directly or indirectly solicit away
employees or consultants of the Company for Employee’s own benefit or for the benefit of any other person or entity. During and after Employee’s Termination, Employee will not directly or indirectly solicit or otherwise take away customers
or suppliers of the Company if, in so doing, Employee uses or discloses any trade secrets or proprietary or confidential information of the Company. Employee agrees that the non-public names and addresses of the Company’s customers and
suppliers, and all other confidential information related to them, including their buying and selling habits and special needs, created or obtained by Employee during Employee’s employment, constitute trade secrets or proprietary or
confidential information of the Company. 

  

	 	11.	No Assignment By Employee. This Agreement, and any of the rights hereunder, may not be assigned or otherwise transferred, in whole or in part by Employee.


  

	 	12.	Arbitration. Any and all controversies arising out of or relating to the validity, interpretation, enforceability, or performance of this Agreement will be
solely and finally settled by means of binding arbitration. Any arbitration shall be conducted in accordance with the then-current Employment Dispute Resolution Rules of the American Arbitration Association. The arbitration will be final, conclusive
and binding upon the parties. All arbitrator’s fees and related expenses shall be divided equally between the parties. Further, each party shall bear its own attorney’s fees and costs incurred in connection with the arbitration.


  

	 	13.	 Equitable Relief. Each party acknowledges and agrees that a breach of any term or condition of this Agreement may cause the non-breaching party
irreparable harm for which its remedies at law may be inadequate. Each party hereby agrees that the non-breaching party will be entitled, in 



  
 3 









	 	
addition to any other remedies available to it at law or in equity, to seek injunctive relief to prevent the breach or threatened breach of the other party’s obligations hereunder.
Notwithstanding Paragraph 12, above, the parties may seek injunctive relief through the civil court rather than through private arbitration if necessary to prevent irreparable harm. 


 

	 	14.	No Admission. The execution of this Agreement and the performance of its terms shall in no way be construed as an admission of guilt or liability by either
Employee or Employer. Both parties expressly disclaim any liability for claims by the other. 

  

	 	15.	Consultation With Counsel and Time to Consider. Employee has been advised to consult an attorney before signing this Agreement. Employee acknowledges that
Employee has been given the opportunity to consult counsel of Employee’s choice before signing this Agreement, and that Employee is fully aware of the contents and legal effect of this Agreement. Employee acknowledges that Employer has provided
Employee with a list, which is Attachment A to this Agreement, of the job titles and ages of all employees being terminated on the Separation Date as well as the ages of the employees with the same titles who are not being terminated
(“OWBPA Information”). Employee has been given forty-five (45) days from receipt of the OWBPA Information to consider this Agreement. 


 

	 	16.	Right to Revoke. 

  

	 	a.	Employee and Employer have seven (7) days from the date Employee signs this Agreement to revoke it in a writing delivered to the other party. After that seven
(7) day period has elapsed, this Agreement is final and binding on both parties. 

  

	 	b.	Employee acknowledges and understands that if Employee fails to provide the Employer with an executed copy of this Agreement by the date indicated in Recital C on the
first page of this Agreement, Employer’s offer to enter into this Agreement and/or its execution of this Agreement is automatically revoked and Employee shall forfeit all rights under the Plan. 


 

	 	17.	Severability. It is the desire and intent of the parties that the provisions of this Agreement shall be enforced to the fullest extent permissible under the laws
and public policies applied in each jurisdiction in which enforcement is sought. Accordingly, although Employer and Employee consider the restrictions contained in this Agreement to be reasonable for the purpose of preserving Employer’s
goodwill and proprietary rights, if any provision or portion of this Agreement shall be determined to be invalid or unenforceable for any reason, the remaining provisions or portions of this Agreement shall be unaffected thereby and shall remain in
full force and effect to the fullest extent permitted by law. 

  

	 	18.	Entire Agreement. This Agreement together with the Plan and the Proprietary Information Agreement represents the complete understanding of Employee and Employer
with respect to the subject matter herein. 

  

	 	19.	Notices. Notices or other communications given pursuant to this Agreement shall be given in accordance with the Plan. 


 

	 	20.	Governing Law. This Agreement will be construed and enforced in accordance with the laws of California (not including any California law that would require the
substantive law of another jurisdiction to apply).

	 	21.	Counterparts. This Agreement may be executed in two or more counterparts, all of which shall be considered one and the same agreement.
