	 	5.	 Termination of Employment 



5.1 At-Will Employment. Executive’s employment relationship is at-will. Either Executive or the Company may terminate the employment relationship at any time, with or without Cause (as defined herein) or advance notice. 

5.2 Termination Without Cause or Resignation for Good Reason Following a Change in Control. If, on or within eighteen
(18) months after the effective date of a Change in Control (as defined herein), the Company terminates Executive’s employment without Cause (as defined herein) and other than as a result of her death or disability, or Executive resigns
for Good Reason (as defined herein), and provided such termination or resignation constitutes a “separation from service” (within the meaning of Treasury Regulation Section 1.409A-l(h)), and
Executive signs the Company’s standard form of release within the time period specified by the Company and allows it to become effective in accordance with its terms but in no event later than 60 days following Executive’s termination, and
provided Executive complies with Executive’s obligations under Executive’s Employee Proprietary Information and Inventions Agreement, then the Company shall provide Executive with the following severance benefits: 

(i) Salary and Benefit Continuation. The Company will pay Executive severance in the form of continuation of Executive’s
Base Salary (at the rate then in effect) for a nine (9) month period following Executive’s last day of employment, in addition to any accrued salary, the accrued but unpaid portion of Executive’s bonus, if any, and accrued and unused
vacation, through Executive’s last day of employment. These salary continuation payments will be paid on the Company’s regular payroll schedule and subject to standard deductions and withholdings over the applicable period following
termination; provided, however, that no payments will be made prior to the 60th day following Executive’s termination. On the 60th
day following Executive’s termination date, the Company will pay Executive in a lump sum the salary continuation payments that Executive would have received on or prior to such date under the original schedule but for the delay while waiting
for the release deadline, with the balance of the cash severance being paid as originally scheduled. Each such installment will be deemed a separate “payment” for purposes of Section 409A of the Code. In addition, Executive shall have
the right to continue her health insurance 

  
 3 













 
benefits pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”) or successor statute and any analogous provisions of applicable state law. Provided that
Executive makes a timely and accurate election for continued health insurance coverage (including medical, dental, vision and prescription) under COBRA (or any state law of similar effect), the Company will pay the premiums for such continued
coverage for Executive and her eligible dependents for the first nine (9) months of such coverage, or such earlier date as Executive (or her dependents, as applicable) ceases to be eligible for such continuation coverage. 

(ii) Accelerated Vesting. The Company will accelerate the vesting of the Stock Rights, to the extent then-outstanding and
unvested, such that all shares subject to the Stock Rights shall be deemed immediately vested and exerciseable as of Executive’s termination date. 

5.3 Termination Without Cause or Resignation for Good Reason Not Following a Change in Control. If at any time other than on or
within eighteen (18) months following the effective date of a Change in Control, the Company terminates Executive’s employment without Cause or Executive resigns for Good Reason, then Executive will not be entitled to any further
compensation from the Company (other than accrued salary, and accrued and unused vacation, through Executive’s last day of employment), including severance pay, pay in lieu of notice or any other such compensation. 

5.4 Termination for Cause; Resignation Without Good Reason. If at any time, the Company terminates Executive’s employment
with the Company for Cause, or Executive resigns without Good Reason, then Executive will not be entitled to any further compensation from the Company (other than accrued salary, the accrued but unpaid portion of Executive’s bonus, if any, and
accrued and unused vacation, through Executive’s last day of employment), including severance pay, pay in lieu of notice or any other such compensation. 

5.5 Section 409A Compliance. It is intended that each installment of the severance payments and benefits provided for in this
Agreement is a separate “payment” for purposes of Section 409A. For the avoidance of doubt, it is intended that the severance satisfies, to the greatest extent possible, the exemptions from the application of Section 409A
provided under Treasury Regulation 1.409A-l(b)(4) and 1.409A-l(b)(9). Notwithstanding the foregoing, if the Company (or, if applicable, the successor entity thereto)
determines that the severance payment provided above upon a separation from service constitute “deferred compensation” under Section 409A of the Internal Revenue Code (together, with any state law of similar effect,
“Section 409A”) and if Executive is a “specified employee” of the Company or any successor entity thereto as of the separation from service, as such term is defined in Section 409A(a)(2)(B)(i) (a “Specified
Employee”), then, solely to the extent necessary to avoid the incurrence of the adverse personal tax consequences under Section 409A, the timing of the severance (or any portion thereof) shall be delayed as follows: on the earlier to occur
of (i) the date that is six months and one day after the date of separation of service or (ii) the date of Executive’s death (such earlier date, the “Delayed Initial Payment Date”), the Company (or the successor entity
thereto, as applicable) shall (A) pay to Executive a lump sum amount equal to the sum of the severance payments that Executive would otherwise have received through the Delayed Initial Payment Date if the commencement of the payment of the
severance had not been delayed pursuant to this paragraph and (B) commence paying the balance of the severance in accordance with the payment schedule set forth above.

Executive’s duties that has not been cured within 30 days after written notice from the Board of such breach; (d) intentional and material damage to the Company’s property; (e) material breach of the Proprietary Information and
