 RECITALS 
 WHEREAS: It is expected that the Company from time to time will consider the possibility of an acquisition by another
company or other change of control. The Board of Directors of the Company (the “Board”) recognizes that such consideration can be a distraction to Executive and can cause Executive to consider alternative employment opportunities. The

of Control of the Company. 
 WHEREAS: The Board believes that it is in the best interests of the Company and its shareholders to provide Executive with an
incentive to continue his or her employment and to motivate Executive to maximize the value of the Company upon a Change of Control for the benefit of its shareholders. 
 WHEREAS: The Board believes that it is imperative to provide Executive with certain severance benefits upon Executive’s termination of employment following a Change of Control. These benefits will provide
Executive with enhanced financial security and incentive and encouragement to remain with the Company notwithstanding the possibility of a Change of Control.

 (a) The vesting of each of Executive’s then outstanding options to purchase shares of the Company’s Common Stock (each, an “Option
Grant”) shall immediately be accelerated by a number of months equal to (i) the number of months over which such Option Grant would continue vesting as of the date of the Change of Control if the Executive remained a service provider to

 9. Severance Benefits. 
 (a) Involuntary Termination Following a Change of Control. If within eighteen (18) months following a Change of Control (X)(i) Executive

(Y) Executive signs and does not revoke a standard release of claims with the Company in a form reasonably acceptable to the Company, then Executive shall receive the following severance from the Company: 
 (i) Severance Payment. Executive will be entitled to (i) receive continuing payments of severance pay (less applicable withholding taxes) at
a rate equal to his base salary rate, as then in effect, for a period of twelve (12) months from the date of such termination, to be paid periodically in accordance with the Company’s normal payroll policies; and (B) a lump-sum
payment equal to 100% of Executive’s target annual bonus as of the date of such termination.

All of Executive’s then outstanding options to purchase shares of the Company’s Common Stock (the “Options”) shall immediately vest and become exercisable (that is, in addition to the shares subject to the Options which have
vested and become exercisable as of the date of such termination), but in no event shall the number of shares subject to such Options which so vest exceed the total number of shares subject to such Options. Additionally, all of the shares of the
Company’s Common Stock then held by Executive subject to a Company right of repurchase (the “Restricted Stock”) shall immediately vest and have such Company right of repurchase with respect to such shares of Restricted Stock lapse
(that is, in addition to the shares of Restricted Stock which have vested as of the date of such termination), but in no event shall the number of shares which so vest exceed the number of shares of Restricted Stock outstanding immediately prior to
such termination. 
 (iii) Continued Employee Benefits. Executive shall receive Company-paid coverage for Executive and
Executive’s eligible dependents under the Company’s Benefit Plans for a period equal to the shorter of (i) twelve (12) months or (ii) such time as Executive secures employment with benefits generally similar to those
provided in the Company’s Benefit Plans. 
 (b) Timing of Severance Payments. Any lump-sum severance payment to which Executive
is entitled shall be paid by the Company to Executive in cash and in full, not later than ten (10) calendar days after the date of the termination of Executive’s employment as provided in 

  

 -3- 

 
Section 9(a), and any other severance payments shall be paid in accordance with normal payroll policies as provided in Section 9(a). If Executive
should die before all amounts have been paid, such unpaid amounts shall be paid in a lump-sum payment to Executive’s designated beneficiary, if living, or otherwise to the personal representative of Executive’s estate. 
 (c) Voluntary Resignation; Termination for Cause. If Executive’s employment with the Company terminates (i) voluntarily by Executive
other than for Good Reason or (ii) for Cause by the Company, then Executive shall not be entitled to receive severance or other benefits except for those as may then be established under the Company’s then existing severance and Benefits
Plans or pursuant to other written agreements with the Company. 
 (d) Disability; Death. If the Company terminates Executive’s
employment as a result of Executive’s Disability, or Executive’s employment terminates due to his or her death, then Executive shall not be entitled to receive severance or other benefits except for severance amounts paid to Executive
prior to the date of such termination and except for those as may then be established under the Company’s then existing written severance and Benefits Plans or pursuant to other written agreements with the Company. 
 (e) Termination Apart from Change of Control. In the event Executive’s employment is terminated for any reason, either prior to the
occurrence of a Change of Control or after the eighteen (18) month period following a Change of Control, then Executive shall be entitled to receive severance and any other benefits only as may then be established under the Company’s
existing written severance and Benefits Plans, if any, or pursuant to any other written agreements with the Company. 
 (f) Exclusive
Remedy. In the event of a termination of Executive’s employment within eighteen (18) months following a Change of Control, the provisions of this Section 9 are intended to be and are exclusive and in lieu of any other rights or
remedies to which Executive or the Company may otherwise be entitled, whether at law, tort or contract, in equity, or under this Agreement. Executive shall be entitled to no benefits, compensation or other payments or rights upon termination of
employment following a Change in Control other than those benefits expressly set forth in this Section 9. 
 10. Conditional Nature
of Severance Payments. 
 (a) Non-Solicitation. Until the date one (1) year after the termination of Executive’s
employment with the Company for any reason, Executive agrees not, either directly or indirectly, to solicit, induce, attempt to hire, recruit, encourage, take away, hire any employee of the Company or any successor entity or cause an employee to
leave his or her employment either for Executive or for any other entity or person. Additionally, Executive acknowledges that Executive’s right to receive the severance payments set forth in Section 9 (to the extent Executive is otherwise
entitled to such payments) are contingent upon Executive complying with this Section 10 and upon any breach by Executive of this Section 10: (i) Executive shall refund to the Company all cash paid to Executive pursuant to
Section 9 of this Agreement; and (ii) all severance benefits pursuant to this Agreement shall immediately cease. 
  

 -4- 

 (b) Understanding of Obligations. Executive represents that he (i) is familiar with the
foregoing covenant not to solicit, and (ii) is fully aware of his obligations hereunder, including, without limitation, the reasonableness of the length of time, scope and geographic coverage of such covenant. 
 11. Limitation of Payments. In the event that the severance and other benefits provided for in this Agreement or otherwise payable to Executive
(i) constitute “parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”) and (ii) but for this Section 11, would be subject to the excise tax imposed
by Section 4999 of the Code, then Executive’s benefits hereunder shall be either: 
 (a) delivered in full, or 
 (b) delivered as to such lesser extent which would result in no portion of such severance benefits being subject to 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 Executive on an after-tax basis, of the greatest amount of severance benefits, notwithstanding that all or some portion of such severance benefits may be taxable under Section 4999 of the Code.
Unless the Company and Executive otherwise agree in writing, any determination required under this Section 11 shall be made in writing by the Company’s independent public accountants immediately prior to Change of Control (the
“Accountants”), whose determination shall be conclusive and binding upon Executive and the Company for all purposes. For purposes of making the calculations required by this Section 11, 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 Executive shall furnish to the Accountants such information and
documents as the Accountants may reasonably request in order to make a determination under this Section 11. The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this
Section 11. If there is a reduction pursuant to this Section 11 of the severance benefits to be delivered to Executive, such reduction shall first be applied to any cash amounts to be delivered to the Executive under this Agreement and
thereafter to any other severance benefits of Executive hereunder. 
 12. Definition of Terms. The following terms referred to in this
Agreement shall have the following meanings: 
 (a) Benefit Plans. “Benefit Plans” means plans, policies or arrangements that
the Company sponsors (or participates in) and that immediately prior to Executive’s termination of employment provide Executive and/or Executive’s eligible dependents with medical, dental, vision and/or financial counseling benefits.
Benefit Plans do not include any other type of benefit (including, but not by way of limitation, disability, life insurance or retirement benefits). A requirement that the Company provide Executive and Executive’s eligible dependents with
coverage under the Benefit Plans will not be satisfied unless the coverage is no less favorable than that provided to Executive and Executive’s eligible dependents immediately prior to Executive’s termination of employment. Notwithstanding
any contrary provision of this Section 12, but subject to the immediately preceding sentence, the Company may, at its option, satisfy any requirement that 

  

 -5- 

 
the Company provide coverage under any Benefit Plan by instead providing coverage under a separate plan or plans providing coverage that is no less favorable
or by paying Executive a lump-sum payment sufficient to provide Executive and Executive’s eligible dependents with equivalent coverage under a third party plan that is reasonably available to Executive and Executive’s eligible dependents.

 (b) Cause. “Cause” means any of the following: (i) the failure by you to substantially perform your duties with the
Company (other than due to your incapacity as a result of physical or mental illness for a period not to exceed 90 days); (ii) the engaging by you in conduct which is materially injurious to the Company, its business or reputation, or which
constitutes gross misconduct; (iii) your material breach of the terms of this Agreement, the Invention Agreement or any other agreements between you and the Company; (iv) the material breach or taking of any action in material
contravention of the policies of the Company adopted by the Board or any committee thereof, including, without limitation, the Company’s policies adopted by the Board of Directors or any committee thereof (including, without limitation, a Code
of Ethics, Insider Trading Compliance Program, Disclosure Process and Procedures or Corporate Governance Guidelines, if any such policies are adopted by the Board of Directors); (v) your conviction for or admission or plea of no contest with
respect to a felony; or (vi) an act of fraud against the Company, the misappropriation of material property belonging to the Company, or an act of violence against an officer, director, employee or consultant of the Company; provided, however,
that in the event that any of the foregoing events in (i), (iii) or (iv) is capable of being cured, the Company shall provide written notice to you describing the nature of such event, and you shall thereafter have thirty

 (ii) Any action or event occurring within a two-year period, as a result of which

Board with the affirmative votes of at least a majority of the Incumbent Directors at the time of such election or nomination (but shall not include an individual whose election or nomination is in connection with an actual or threatened proxy
contest relating to the election of directors to the Company); or 
 (iii) The consummation of a merger or consolidation of the Company with
any other corporation, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting

 -6- 

 (iv) The consummation of the sale, lease or other disposition by the Company of all or substantially all
the Company’s assets. 
 Notwithstanding anything to the contrary in this Agreement, a sale and issuance of capital stock of the Company
in one transaction or a series of related transactions in a bona fide venture capital financing for capital raising purposes in which the holders of capital stock of the Company before the financing do not hold at least a majority of the voting
power of the Company after the financing shall not constitute a “Change of Control” for purposes of this Agreement 
 (d)
Disability. “Disability” shall mean that Executive has been unable to perform his Company duties as the result of his incapacity due to physical or mental illness, and such inability, at least twenty-six (26) weeks after its

 13. Arbitration. 
 (a) General. In
consideration of Executive’s service to the Company, its promise to arbitrate all employment related disputes and Executive’s receipt of the compensation, pay raises and other benefits paid to Executive by the Company, at present and in
the future, Executive agrees that any and all controversies, claims, or disputes with anyone (including the Company and any employee, officer, director, shareholder or benefit plan of the Company in their capacity as such or otherwise) arising out
of, relating to, or resulting from Executive’s service to the Company under this Agreement or otherwise or the termination of Executive’s service with the Company, including any breach of this Agreement, will be subject to binding
arbitration under the Arbitration Rules set forth in California Code of Civil Procedure Section 1280 through 1294.2, including Section 1283.05 (the “Rules”) and pursuant to California law. Disputes which Executive agrees
to arbitrate, and thereby agrees to waive any right to a trial by jury, include any statutory claims under state or federal 

  

 -7- 

 
law, including, but not limited to, claims under Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act of 1990, the Age
Discrimination in Employment Act of 1967, the Older Workers Benefit Protection Act, the California Fair Employment and Housing Act, the California Labor Code, claims of harassment, discrimination or wrongful termination and any statutory claims.
Executive further understands that this Agreement to arbitrate also applies to any disputes that the Company may have with Executive. 
 (b)
Procedure. Executive agrees that any arbitration will be administered by the American Arbitration Association (“AAA”) and that a neutral arbitrator will be selected in a manner consistent with its National Rules for the
Resolution of Employment Disputes. The arbitration proceedings will allow for discovery according to the rules set forth in the National Rules for the Resolution of Employment Disputes or California Code of Civil Procedure. Executive agrees
that the arbitrator will have the power to decide any motions brought by any party to the arbitration, including motions for summary judgment and/or adjudication and motions to dismiss and demurrers, prior to any arbitration hearing. Executive
agrees that the arbitrator will issue a written decision on the merits. Executive also agrees that the arbitrator will have the power to award any remedies, including attorneys’ fees and costs, available under applicable law. Executive
understands the Company will pay for any administrative or hearing fees charged by the arbitrator or AAA except that Executive will pay the first $125.00 of any filing fees associated with any arbitration Executive initiates. Executive agrees that
the arbitrator will administer and conduct any arbitration in a manner consistent with the Rules and that to the extent that the AAA’s National Rules for the Resolution of Employment Disputes conflict with the Rules, the Rules will take
precedence. 
 (c) Remedy. Except as provided by the Rules, arbitration will be the sole, exclusive and final remedy for any dispute
between Executive and the Company. Accordingly, except as provided for by the Rules, neither Executive nor the Company will be permitted to pursue court action regarding claims that are subject to arbitration. Notwithstanding, the arbitrator will
not have the authority to disregard or refuse to enforce any lawful Company policy, and the arbitrator will not order or require the Company to adopt a policy not otherwise required by law which the Company has not adopted. 
 (d) Availability of Injunctive Relief. In addition to the right under the Rules to petition the court for provisional relief, Executive agrees
that any party may also petition the court for injunctive relief where either party alleges or claims a violation of this Agreement or the Confidentiality Agreement or any other agreement regarding trade secrets, confidential information,
nonsolicitation or Labor Code §2870. In the event either party seeks injunctive relief, the prevailing party will be entitled to recover reasonable costs and attorneys fees. 
 (e) Administrative Relief. Executive understands that this Agreement does not prohibit Executive from pursuing an administrative claim with a
local, state or federal administrative body such as the Department of Fair Employment and Housing, the Equal Employment Opportunity Commission or the workers’ compensation board. This Agreement does, however, preclude Executive from pursuing
court action regarding any such claim. 
 (f) Voluntary Nature of Agreement. Executive acknowledges and agrees that Executive is
executing this Agreement voluntarily and without any duress or undue influence by the Company or anyone else. Executive further acknowledges and agrees that Executive has carefully 

  

 -8- 

 
read this Agreement and that Executive has asked any questions needed for Executive to understand the terms, consequences and binding effect of this
Agreement and fully understand it, including that Executive is waiving Executive’s right to a jury trial. Finally, Executive agrees that Executive has been provided an opportunity to seek the advice of an attorney of Executive’s choice
before signing this Agreement. 
 14. Successors. 
 (a) The Company’s Successors. Any successor to the Company (whether direct or indirect and whether by purchase, merger, consolidation, liquidation or otherwise, and including, without limitation, a parent
entity of any successor to the Company) to all or substantially all of the Company’s business and/or assets shall assume the obligations under this Agreement and agree expressly to perform the obligations under this Agreement in the same manner
and to the same extent as the Company would be required to perform such obligations in the absence of a succession. For all purposes under this Agreement, 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 Section 14(a) or which becomes bound by the terms of this Agreement by operation of law. 
 (b) The Executive’s Successors. The terms of this Agreement and all rights of Executive hereunder shall inure to the benefit of, and be
enforceable by, Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees.

 (a) General. Notices and all other communications contemplated by this Agreement
shall be in writing and shall be deemed to have been duly given when personally delivered or when mailed by U.S. registered or certified mail, return receipt requested and postage prepaid. In the case of Executive, mailed notices shall be addressed
to him or her at the home address which he or she most recently communicated to the Company in writing. In the case of the Company, mailed notices shall be addressed to its corporate headquarters, and all notices shall be directed to the attention
of its Chief Financial Officer. 
 (b) Notice of Termination. Any termination by the Company for Cause or by Executive for Good Reason
or as a result of a voluntary resignation shall be communicated by a notice of termination to the other party hereto given in accordance with Section 15(a) of this Agreement. Such notice shall indicate the specific termination provision in this
Agreement 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 (which shall be not more than thirty
(30) days after the giving of such notice). 
 16. Miscellaneous Provisions. 
 (a) No Duty to Mitigate. Executive shall not be required to mitigate the amount of any payment contemplated by this Agreement, nor, except as
otherwise contemplated in this Agreement, shall any such payment be reduced by any earnings that Executive may receive from any other source.

 (b) Waiver. No provision of this Agreement shall be modified, waived or discharged unless the
modification, waiver or discharge is agreed to in writing and signed by Executive and by an authorized officer of the Company (other than Executive). No waiver by either party of any breach of, or of compliance with, any condition or provision of
this Agreement 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. 
 (c) Headings. All captions and section headings used in this Agreement are for convenient reference only and do not form a part of this Agreement.

The laws of the State of California (without reference to its choice of laws provisions) shall govern the validity, interpretation, construction and performance of this Agreement. 
 (f) Severability. The invalidity or unenforceability of any provision or provisions of this Agreement shall not affect the validity or
enforceability of any other provision hereof, which shall remain in full force and effect.

 8. Acceleration of Vesting Upon a Change of Control. Upon a Change of Control of the Company: 
 (a) The vesting of each of Executive’s then outstanding options to purchase shares of the Company’s Common Stock (each, an “Option
Grant”) shall immediately be accelerated by a number of months equal to (i) the number of months over which such Option Grant would continue vesting as of the date of the Change of Control if the Executive remained a service provider to
the Company during such period (the “Vesting Months”), minus (ii) the lower of (A) eighteen months or (B) the Vesting Months; and 
  

 -2- 

 (b) The lapse of the Company’s right of repurchase with respect to each restricted stock grant
pursuant to which the Executive holds shares of the Company’s Common Stock (each, a “Restricted Stock Grant”) shall immediately be accelerated by a number of months equal to (i) the number of months over which the Company’s
right of repurchase would continue to lapse with respect to any such Restricted Stock Grant as of the date of the Change of Control if the Executive remained a service provider to the Company during such period (the “Lapsing Months”),
minus (ii) the lower of (A) eighteen months or (B) the Lapsing Months. 
 9. Severance Benefits. 
 (a) Involuntary Termination Following a Change of Control. If within eighteen (18) months following a Change of Control (X)(i) Executive
terminates his or her employment with the Company (or any parent or subsidiary of the Company) for Good Reason or (ii) the Company (or any parent or subsidiary of the Company) terminates Executive’s employment for other than Cause, and
(Y) Executive signs and does not revoke a standard release of claims with the Company in a form reasonably acceptable to the Company, then Executive shall receive the following severance from the Company: 
 (i) Severance Payment. Executive will be entitled to (i) receive continuing payments of severance pay (less applicable withholding taxes) at
a rate equal to his base salary rate, as then in effect, for a period of nine (9) months from the date of such termination, to be paid periodically in accordance with the Company’s normal payroll policies; and (B) a lump-sum payment
equal to 100% of Executive’s target annual bonus as of the date of such termination. 
 (ii) Options; Restricted Stock. All of
Executive’s then outstanding options to purchase shares of the Company’s Common Stock (the “Options”) shall immediately vest and become exercisable (that is, in addition to the shares subject to the Options which have vested and
become exercisable as of the date of such termination), but in no event shall the number of shares subject to such Options which so vest exceed the total number of shares subject to such Options. Additionally, all of the shares of the Company’s
Common Stock then held by Executive subject to a Company right of repurchase (the “Restricted Stock”) shall immediately vest and have such Company right of repurchase with respect to such shares of Restricted Stock lapse (that is, in
addition to the shares of Restricted Stock which have vested as of the date of such termination), but in no event shall the number of shares which so vest exceed the number of shares of Restricted Stock outstanding immediately prior to such
termination. 
 (iii) Continued Employee Benefits. Executive shall receive Company-paid coverage for Executive and Executive’s
eligible dependents under the Company’s Benefit Plans for a period equal to the shorter of (i) nine (9) months or (ii) such time as Executive secures employment with benefits generally similar to those provided in the
Company’s Benefit Plans. 
 (b) Timing of Severance Payments. Any lump-sum severance payment to which Executive is entitled shall
be paid by the Company to Executive in cash and in full, not later than ten (10) calendar days after the date of the termination of Executive’s employment as provided in 

  

 -3- 

 
Section 9(a), and any other severance payments shall be paid in accordance with normal payroll policies as provided in Section 9(a). If Executive
should die before all amounts have been paid, such unpaid amounts shall be paid in a lump-sum payment to Executive’s designated beneficiary, if living, or otherwise to the personal representative of Executive’s estate. 
 (c) Voluntary Resignation; Termination for Cause. If Executive’s employment with the Company terminates (i) voluntarily by Executive
other than for Good Reason or (ii) for Cause by the Company, then Executive shall not be entitled to receive severance or other benefits except for those as may then be established under the Company’s then existing severance and Benefits
Plans or pursuant to other written agreements with the Company. 
 (d) Disability; Death. If the Company terminates Executive’s
employment as a result of Executive’s Disability, or Executive’s employment terminates due to his or her death, then Executive shall not be entitled to receive severance or other benefits except for severance amounts paid to Executive
prior to the date of such termination and except for those as may then be established under the Company’s then existing written severance and Benefits Plans or pursuant to other written agreements with the Company. 
 (e) Termination Apart from Change of Control. In the event Executive’s employment is terminated for any reason, either prior to the
occurrence of a Change of Control or after the eighteen (18) month period following a Change of Control, then Executive shall be entitled to receive severance and any other benefits only as may then be established under the Company’s
existing written severance and Benefits Plans, if any, or pursuant to any other written agreements with the Company. 
 (f) Exclusive
Remedy. In the event of a termination of Executive’s employment within eighteen (18) months following a Change of Control, the provisions of this Section 9 are intended to be and are exclusive and in lieu of any other rights or
remedies to which Executive or the Company may otherwise be entitled, whether at law, tort or contract, in equity, or under this Agreement. Executive shall be entitled to no benefits, compensation or other payments or rights upon termination of
employment following a Change in Control other than those benefits expressly set forth in this Section 9. 
 10. Conditional Nature
of Severance Payments. 
 (a) Non-Solicitation. Until the date one (1) year after the termination of Executive’s
employment with the Company for any reason, Executive agrees not, either directly or indirectly, to solicit, induce, attempt to hire, recruit, encourage, take away, hire any employee of the Company or any successor entity or cause an employee to
leave his or her employment either for Executive or for any other entity or person. Additionally, Executive acknowledges that Executive’s right to receive the severance payments set forth in Section 9 (to the extent Executive is otherwise
entitled to such payments) are contingent upon Executive complying with this Section 10 and upon any breach by Executive of this Section 10: (i) Executive shall refund to the Company all cash paid to Executive pursuant to
Section 9 of this Agreement; and (ii) all severance benefits pursuant to this Agreement shall immediately cease. 
  

 -4- 

 (b) Understanding of Obligations. Executive represents that he (i) is familiar with the
foregoing covenant not to solicit, and (ii) is fully aware of his obligations hereunder, including, without limitation, the reasonableness of the length of time, scope and geographic coverage of such covenant. 
 11. Limitation of Payments. In the event that the severance and other benefits provided for in this Agreement or otherwise payable to Executive
(i) constitute “parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”) and (ii) but for this Section 11, would be subject to the excise tax imposed
by Section 4999 of the Code, then Executive’s benefits hereunder shall be either: 
 (a) delivered in full, or 
 (b) delivered as to such lesser extent which would result in no portion of such severance benefits being subject to 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 Executive on an after-tax basis, of the greatest amount of severance benefits, notwithstanding that all or some portion of such severance benefits may be taxable under Section 4999 of the Code.
Unless the Company and Executive otherwise agree in writing, any determination required under this Section 11 shall be made in writing by the Company’s independent public accountants immediately prior to Change of Control (the
“Accountants”), whose determination shall be conclusive and binding upon Executive and the Company for all purposes. For purposes of making the calculations required by this Section 11, 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 Executive shall furnish to the Accountants such information and
documents as the Accountants may reasonably request in order to make a determination under this Section 11. The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this
Section 11. If there is a reduction pursuant to this Section 11 of the severance benefits to be delivered to Executive, such reduction shall first be applied to any cash amounts to be delivered to the Executive under this Agreement and
thereafter to any other severance benefits of Executive hereunder. 
 12. Definition of Terms. The following terms referred to in this
Agreement shall have the following meanings: 
 (a) Benefit Plans. “Benefit Plans” means plans, policies or arrangements that
the Company sponsors (or participates in) and that immediately prior to Executive’s termination of employment provide Executive and/or Executive’s eligible dependents with medical, dental, vision and/or financial counseling benefits.
Benefit Plans do not include any other type of benefit (including, but not by way of limitation, disability, life insurance or retirement benefits). A requirement that the Company provide Executive and Executive’s eligible dependents with
coverage under the Benefit Plans will not be satisfied unless the coverage is no less favorable than that provided to Executive and Executive’s eligible dependents immediately prior to Executive’s termination of employment. Notwithstanding
any contrary provision of this Section 12, but subject to the immediately preceding sentence, the Company may, at its option, satisfy any requirement that 

  

 -5- 

 
the Company provide coverage under any Benefit Plan by instead providing coverage under a separate plan or plans providing coverage that is no less favorable
or by paying Executive a lump-sum payment sufficient to provide Executive and Executive’s eligible dependents with equivalent coverage under a third party plan that is reasonably available to Executive and Executive’s eligible dependents.

 (b) Cause. “Cause” means any of the following: (i) the failure by you to substantially perform your duties with the
Company (other than due to your incapacity as a result of physical or mental illness for a period not to exceed 90 days); (ii) the engaging by you in conduct which is materially injurious to the Company, its business or reputation, or which
constitutes gross misconduct; (iii) your material breach of the terms of this Agreement, the Invention Agreement or any other agreements between you and the Company; (iv) the material breach or taking of any action in material
contravention of the policies of the Company adopted by the Board or any committee thereof, including, without limitation, the Company’s policies adopted by the Board of Directors or any committee thereof (including, without limitation, a Code
of Ethics, Insider Trading Compliance Program, Disclosure Process and Procedures or Corporate Governance Guidelines, if any such policies are adopted by the Board of Directors); (v) your conviction for or admission or plea of no contest with
respect to a felony; or (vi) an act of fraud against the Company, the misappropriation of material property belonging to the Company, or an act of violence against an officer, director, employee or consultant of the Company; provided, however,
that in the event that any of the foregoing events in (i), (iii) or (iv) is capable of being cured, the Company shall provide written notice to you describing the nature of such event, and you shall thereafter have thirty
(30) business days to cure such event. 
 (c) Change of Control. “Change of Control” means the occurrence of any of the
following: 
 (i) Any “person” (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as
amended) becomes the “beneficial owner” (as defined in Rule 13d-3 under said Act), directly or indirectly, of securities of the Company representing fifty percent (50%) or more of the total voting power represented by the
Company’s then outstanding voting securities; or 
 (ii) Any action or event occurring within a two-year period, as a result of which
fewer than a majority of the directors are Incumbent Directors. “Incumbent Directors” shall mean directors who either (A) are directors of the Company as of the date hereof, or (B) are elected, or nominated for election, to the
Board with the affirmative votes of at least a majority of the Incumbent Directors at the time of such election or nomination (but shall not include an individual whose election or nomination is in connection with an actual or threatened proxy
contest relating to the election of directors to the Company); or 
 (iii) The consummation of a merger or consolidation of the Company with
any other corporation, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting
securities of the surviving entity) at least fifty percent (50%) of the total voting power represented by the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation; or 

 

 -6- 

 (iv) The consummation of the sale, lease or other disposition by the Company of all or substantially all
the Company’s assets. 
 Notwithstanding anything to the contrary in this Agreement, a sale and issuance of capital stock of the Company
in one transaction or a series of related transactions in a bona fide venture capital financing for capital raising purposes in which the holders of capital stock of the Company before the financing do not hold at least a majority of the voting
power of the Company after the financing shall not constitute a “Change of Control” for purposes of this Agreement 
 (d)
Disability. “Disability” shall mean that Executive has been unable to perform his Company duties as the result of his incapacity due to physical or mental illness, and such inability, at least twenty-six (26) weeks after its

 (e) Good Reason. “Good Reason” means any of the following unless such event is agreed to, in writing or as set forth below, by you: (i) a material reduction in your salary or benefits (excluding the substitution of
substantially equivalent compensation and benefits), other than as a result of a reduction in compensation affecting employees of the Company, or its successor entity, generally; (ii) a material diminution of your duties or responsibilities
relative to your duties and responsibilities in effect immediately prior to the Change of Control, provided however, that a mere change in your title or reporting relationship alone shall not constitute “Good Reason;” (iii) relocation

Agreement. If any of the events set forth above shall occur, you shall give prompt written notice of such event to the Company, or its successor entity, and if such event is not cured within thirty (30) days from such notice you may exercise
your rights to resign for Good Reason, provided that if you have not exercised such right within 45 days of the date of such notice you shall be deemed to have agreed to the occurrence of such event. 
 13. Arbitration. 
 (a) General. In
consideration of Executive’s service to the Company, its promise to arbitrate all employment related disputes and Executive’s receipt of the compensation, pay raises and other benefits paid to Executive by the Company, at present and in
the future, Executive agrees that any and all controversies, claims, or disputes with anyone (including the Company and any employee, officer, director, shareholder or benefit plan of the Company in their capacity as such or otherwise) arising out
of, relating to, or resulting from Executive’s service to the Company under this Agreement or otherwise or the termination of Executive’s service with the Company, including any breach of this Agreement, will be subject to binding
arbitration under the Arbitration Rules set forth in California Code of Civil Procedure Section 1280 through 1294.2, including Section 1283.05 (the “Rules”) and pursuant to California law. Disputes which Executive agrees
to arbitrate, and thereby agrees to waive any right to a trial by jury, include any statutory claims under state or federal 

  

 -7- 

 
law, including, but not limited to, claims under Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act of 1990, the Age
Discrimination in Employment Act of 1967, the Older Workers Benefit Protection Act, the California Fair Employment and Housing Act, the California Labor Code, claims of harassment, discrimination or wrongful termination and any statutory claims.
Executive further understands that this Agreement to arbitrate also applies to any disputes that the Company may have with Executive. 
 (b)
Procedure. Executive agrees that any arbitration will be administered by the American Arbitration Association (“AAA”) and that a neutral arbitrator will be selected in a manner consistent with its National Rules for the
Resolution of Employment Disputes. The arbitration proceedings will allow for discovery according to the rules set forth in the National Rules for the Resolution of Employment Disputes or California Code of Civil Procedure. Executive agrees
that the arbitrator will have the power to decide any motions brought by any party to the arbitration, including motions for summary judgment and/or adjudication and motions to dismiss and demurrers, prior to any arbitration hearing. Executive
agrees that the arbitrator will issue a written decision on the merits. Executive also agrees that the arbitrator will have the power to award any remedies, including attorneys’ fees and costs, available under applicable law. Executive
understands the Company will pay for any administrative or hearing fees charged by the arbitrator or AAA except that Executive will pay the first $125.00 of any filing fees associated with any arbitration Executive initiates. Executive agrees that
the arbitrator will administer and conduct any arbitration in a manner consistent with the Rules and that to the extent that the AAA’s National Rules for the Resolution of Employment Disputes conflict with the Rules, the Rules will take
precedence. 
 (c) Remedy. Except as provided by the Rules, arbitration will be the sole, exclusive and final remedy for any dispute
between Executive and the Company. Accordingly, except as provided for by the Rules, neither Executive nor the Company will be permitted to pursue court action regarding claims that are subject to arbitration. Notwithstanding, the arbitrator will
not have the authority to disregard or refuse to enforce any lawful Company policy, and the arbitrator will not order or require the Company to adopt a policy not otherwise required by law which the Company has not adopted. 
 (d) Availability of Injunctive Relief. In addition to the right under the Rules to petition the court for provisional relief, Executive agrees
that any party may also petition the court for injunctive relief where either party alleges or claims a violation of this Agreement or the Confidentiality Agreement or any other agreement regarding trade secrets, confidential information,
nonsolicitation or Labor Code §2870. In the event either party seeks injunctive relief, the prevailing party will be entitled to recover reasonable costs and attorneys fees. 
 (e) Administrative Relief. Executive understands that this Agreement does not prohibit Executive from pursuing an administrative claim with a
local, state or federal administrative body such as the Department of Fair Employment and Housing, the Equal Employment Opportunity Commission or the workers’ compensation board. This Agreement does, however, preclude Executive from pursuing
court action regarding any such claim. 
 (f) Voluntary Nature of Agreement. Executive acknowledges and agrees that Executive is
executing this Agreement voluntarily and without any duress or undue influence by the Company or anyone else. Executive further acknowledges and agrees that Executive has carefully 

  

 -8- 

 
read this Agreement and that Executive has asked any questions needed for Executive to understand the terms, consequences and binding effect of this
Agreement and fully understand it, including that Executive is waiving Executive’s right to a jury trial. Finally, Executive agrees that Executive has been provided an opportunity to seek the advice of an attorney of Executive’s choice
before signing this Agreement. 
 14. Successors. 
 (a) The Company’s Successors. Any successor to the Company (whether direct or indirect and whether by purchase, merger, consolidation, liquidation or otherwise, and including, without limitation, a parent
entity of any successor to the Company) to all or substantially all of the Company’s business and/or assets shall assume the obligations under this Agreement and agree expressly to perform the obligations under this Agreement in the same manner
and to the same extent as the Company would be required to perform such obligations in the absence of a succession. For all purposes under this Agreement, 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 Section 14(a) or which becomes bound by the terms of this Agreement by operation of law. 
 (b) The Executive’s Successors. The terms of this Agreement and all rights of Executive hereunder shall inure to the benefit of, and be
enforceable by, Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. 
 15. Notice. 
 (a) General. Notices and all other communications contemplated by this Agreement
shall be in writing and shall be deemed to have been duly given when personally delivered or when mailed by U.S. registered or certified mail, return receipt requested and postage prepaid. In the case of Executive, mailed notices shall be addressed
to him or her at the home address which he or she most recently communicated to the Company in writing. In the case of the Company, mailed notices shall be addressed to its corporate headquarters, and all notices shall be directed to the attention
of its Chief Financial Officer. 
 (b) Notice of Termination. Any termination by the Company for Cause or by Executive for Good Reason
or as a result of a voluntary resignation shall be communicated by a notice of termination to the other party hereto given in accordance with Section 15(a) of this Agreement. Such notice shall indicate the specific termination provision in this
Agreement 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 (which shall be not more than thirty
(30) days after the giving of such notice). 
 16. Miscellaneous Provisions. 
 (a) No Duty to Mitigate. Executive shall not be required to mitigate the amount of any payment contemplated by this Agreement, nor, except as
otherwise contemplated in this Agreement, shall any such payment be reduced by any earnings that Executive may receive from any other source. 
  

 -9- 

 (b) Waiver. No provision of this Agreement shall be modified, waived or discharged unless the
modification, waiver or discharge is agreed to in writing and signed by Executive and by an authorized officer of the Company (other than Executive). No waiver by either party of any breach of, or of compliance with, any condition or provision of
this Agreement 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. 
 (c) Headings. All captions and section headings used in this Agreement are for convenient reference only and do not form a part of this Agreement. 
 (d) Entire Agreement. This Agreement and the Invention Agreement constitute the entire agreement of the parties hereto and supersedes in their
entirety all prior representations, understandings, undertakings or agreements (whether oral or written and whether expressed or implied) of the parties with respect to the subject matter hereof. No future agreements between the Company and
Executive may supersede this Agreement, unless they are in writing and specifically mentioned this Agreement. 
 (e) Choice of Law.
The laws of the State of California (without reference to its choice of laws provisions) shall govern the validity, interpretation, construction and performance of this Agreement. 
 (f) Severability. The invalidity or unenforceability of any provision or provisions of this Agreement shall not affect the validity or
enforceability of any other provision hereof, which shall remain in full force and effect. 
 (g) Withholding. All payments made
pursuant to this Agreement will be subject to withholding of applicable income and employment taxes. 
 (h) Counterparts. This
Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together will constitute one and the same instrument.
