the time of such termination and (b) 75% of your maximum annual performance-based bonus at the time of such termination, paid in equal installments during the period from the date of the termination until the date that is nine (9) months after
the effective date of the termination (the “Post-COC Severance Period”), which payments shall be paid during the Post-COC Severance Period (or

release that has become irrevocable during such period, with the initial payment including payments that otherwise would have been made during the sixty day period. 

Notwithstanding anything to the contrary in this letter agreement, any payment or benefit due to you under this letter agreement or otherwise will not be paid
or provided during the six (6) month period following your termination of employment if (i) the Company determines, in its good faith judgment, that you are a “specified” employee under Section 409A of the Internal Revenue
Code and any treasury regulations and internal revenue service guidance thereunder (“Section 409A”) and (ii) such payments or benefits are “nonqualified deferred compensation” for purposes of
Section 409A . If the payment of any amounts are delayed as a result of the previous sentence, any cash severance payments due to you pursuant to this letter agreement or otherwise during the first six (6) months after your termination
will accrue during such six month period and will become payable in a lump sum payment on the date six (6) months and one (1) day following the date of your termination. Thereafter, payments will resume in accordance with the applicable

  
 3 

 
schedule set forth in this letter agreement. You agree to work in good faith with the Company to consider amendments to this letter agreement which are necessary or appropriate to avoid
imposition of any additional tax or income recognition under Section 409A prior to the actual payment to you of payments or benefits under this letter agreement. Notwithstanding the foregoing, this letter agreement will be deemed amended,
without any consent required from you, to the extent necessary to avoid imposition of any additional tax or income recognition pursuant to Section 409A prior to actual payments to you under this letter agreement. You and the Company agree to
cooperate with each other and to take reasonably necessary steps in this regard. 
 This letter agreement is intended to comply with the requirements of
Section 409A, including the exceptions thereto, and shall be construed and administered in accordance with such intent. Notwithstanding any other provision of this letter agreement, payments provided under this letter agreement may only be made
upon an event and in a manner that complies with Section 409A or an applicable exemption. Any payments under this letter agreement that may be excluded from Section 409A either as separation pay due to an involuntary separation from
service or as a short-term deferral shall be excluded from Section 409A to the maximum extent possible. For purposes of Section 409A, each installment payment provided under this letter agreement shall be treated as a separate payment. Any
payments to be made under this letter agreement in connection with a termination of employment shall only be made if such termination of employment constitutes a “separation from service” under Section 409A. To the extent that
reimbursements or other in-kind benefits under this letter agreement constitute “nonqualified deferred compensation” for purposes of Section 409A, (i) such expenses or other reimbursements
hereunder shall be made on or prior to the last day of the taxable year following the taxable year in which such expenses were incurred, (ii) no right to such reimbursement or in-kind benefits shall be
subject to liquidation or exchange for another benefit, and (iii) no such reimbursement, expenses eligible for reimbursement, or in-kind benefits provided in any taxable year shall in any way affect the
expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year. Notwithstanding the foregoing, the Company makes no representations that the payments and benefits provided
under this letter agreement comply with Section 409A and in no event shall the Company, any Company affiliates, or their respective employees, officers, directors, agents and representatives (including, without limitation, legal counsel) be
liable for all or any portion of any taxes, penalties, interest or other expenses that may be incurred by you on account of non-compliance with Section 409A. 

  
 4 

 “Cause” shall mean (i) your failure to perform your assigned duties or
responsibilities as an employee of the Company after notice thereof from the Company describing your failure to perform such duties or responsibilities, (ii) your engaging in any act of dishonesty, fraud or misrepresentation, (iii) your
violation of any federal or state law or regulation applicable to the Company’s business, (iv) your breach of any confidentiality agreement or invention assignment agreement between you and the Company, or (v) your being convicted of
or entering a plea of nolo contendere to, any crime or committing any act of moral turpitude. The determination as to whether you are being terminated for Cause will be made in good faith by the Company and will be final and binding on you.

 “Constructive Termination” shall be deemed to occur if, without your written consent, within 90 days following any of the conditions
below, you terminate your employment in accordance with this provision: (A) the Company’s material breach of this letter agreement resulting from the failure of the Company to require any successor to the Company upon a Change in Control
to assume the Company’s obligations under this letter agreement, (B) a material reduction in your job duties or responsibilities inconsistent with your position with the Company and prior duties or responsibilities , provided that neither
(a) the loss of an “interim” position and your reassignment to a position substantially similar to your role prior to such interim position, whether before or after a Change in Control or (b) a mere change in title alone nor
reassignment following a Change in Control to a position that is substantially similar to the position held prior to the Change in Control in terms of job duties or responsibilities shall constitute a material reduction in job responsibilities, or
(C) the request by the Company or its successor to relocate the principal place for performance of your Company duties to a location more than thirty (30) miles from your then-current principal business location; provided that (i) you
have provided written notice of your intent to terminate employment on the basis of a Constructive Termination within sixty (60) days after the Constructive Termination condition first occurs, and (ii) the Company fails to correct the
Constructive Termination within thirty (30) days after receipt of your written notice. 
 In the event that the severance and other payments or
benefits provided for in this letter agreement or otherwise payable to you (i) constitute “parachute payments” within the meaning, of Section 280G of the Code, and (ii) but for this paragraph would be subject to the excise
tax imposed by Section 4999 of the Code (the “Excise Tax”), then your benefits under this letter agreement shall be either 
  

	 	A.	 delivered in full, or 

 

	 	B.	 delivered as to such lesser extent which would result in no portion of such benefits being subject to the
Excise Tax, 

 whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the Excise
Tax, results in the receipt by you on an after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of such benefits may be taxable under Section 4999 of the Code. If a
reduction is 

  
 5 

 
required and no parachute payments constitute nonqualified deferred compensation under Section 409A, you shall be able to select which payments and/or benefits are reduced and the order of
reduction. If a reduction is required and any parachute payments constitute nonqualified deferred compensation under Section 409A, the reduction shall occur in the following order: (i) options whose exercise price exceeds the fair market
value of the optioned equity, (ii) Full Credit Payments (as defined below) that are payable in cash, (iii) non-cash Full Credit Payments that are taxable,
(iv) non-cash Full Credit Payments that are not taxable (v) Partial Credit Payments (as defined below) and (vi) non-cash employee welfare benefits. In
each case, reductions shall be made in reverse chronological order such that the payment or benefit owed on the latest date following the occurrence of the event triggering the excise tax will be the first payment or benefit to be reduced (with
reductions made pro-rata in the event payments or benefits are owed at the same time). The term “Full Credit Payment” means a payment or benefit that if reduced in value by one dollar reduces the
amount of the parachute payment (as defined in Section 280G of the Code) by one dollar. “Partial Credit Payment” means any payment or benefit that is not a Full Credit Payment. 

You understand and agree that by accepting terms of this letter agreement, you represent to the Company that your performance will not breach any other
agreement to which you are a party and that you have not, and will not during the term of your employment with the Company, enter into any oral or written agreement in conflict with any of the provisions of this letter or the Company’s
policies. You are not to bring with you to the Company, or use or disclose to any person associated with the Company, any confidential or proprietary information belonging to any former employer or other person or entity with respect to which you
owe an obligation of confidentiality under any agreement or otherwise. The Company does not need and will not use such information. Also, we expect you to abide by any obligations to refrain from soliciting any person employed by or otherwise
associated with any former employer. 
 This letter agreement and the confidential information and/or inventions assignment agreement between you and the
Company represent the entire agreement and understanding between you and the Company concerning your employment relationship with the Company and supersede in their entirety any and all prior agreements and understandings concerning your employment
relationship with the Company, whether written or oral. Except as specifically provided in this letter agreement, this letter agreement can only be amended in a writing approved by the Board and signed by you and a duly authorized officer of the
Company. Any waiver of a right under this letter agreement must be in writing. The Company will require any successor to all or substantially all of its assets or businesses to assume this letter agreement and perform the Company’s obligations
hereunder. This letter agreement will be governed by California law.
