4. Indemnification; D&O Insurance. Executive shall be entitled to indemnification, advancement of expenses and limitation of

5. At-Will Employment; Termination of Employment. 

(a) At-Will Employment. Executive’s employment with the Company under this Agreement is

(iv) unreimbursed business expenses (collectively, the “Accrued Compensation”). Payment of the Accrued Compensation shall be made upon the date of termination, except as may otherwise be provided under the terms of any
applicable benefit plan or program. 
 (c) Termination without Cause or Resignation for Good Reason. If Executive’s employment is
terminated by the Company without Cause or Executive resigns for Good Reason, the Company shall pay Executive the Accrued Compensation and shall provide the additional payments and benefits set forth in this Section 5(c). As a condition to such
additional payments and benefits, Executive must execute a full release of claims in a form satisfactory to the Company (the “Release”), which Release shall not be revoked and shall become fully effective and irrevocable within
sixty (60) days of Executive’s termination, or such earlier deadline required by the Release (such deadline, the “Release Deadline”). 

(i) The Company shall pay to Executive, on the Release Deadline, a lump sum amount (less applicable payroll deductions) equal to (A) one
(1) times his then current Base Salary, and (B) one (1) times his then current target bonus for the fiscal year in which such termination occurred as if the Company and Executive had fully achieved all applicable performance goals at
their target level and remained employed through the date necessary to receive and fully earn payment of such bonus. 
 (ii) The vesting of
all outstanding stock options, restricted stock units, restricted stock or other compensation based equity awards then held by Executive (the “Equity Awards”) that are subject to time-based vesting shall be accelerated so that the
number of shares vested under such Equity Awards shall equal that number of shares that would have been vested if Executive had continued to render employment services to the Company for a period of twelve (12) continuous months following the
date of Executive’s termination. The vesting of Equity Awards that are subject to performance-based vesting shall accelerate only to the extent provided in the applicable award agreement. In addition, the period following such termination in
which vested stock options or similar Equity Awards may be exercised shall be not be less than three (3) months following such termination.

insurance coverage through a new employer, if Executive elects to continue health insurance coverage under the Consolidated Budget Reconciliation Act of 1985, as amended (“COBRA”), then so long as Executive is paying COBRA premiums,
and beginning in the month following Executive’s termination (or, if later, the Release Deadline, with a catch-up payment for payments deferred pending the Release Deadline), the Company shall pay
Executive a monthly payment equal to the amount that was paid by the Company for such coverage as of the date of termination and any increases in such premiums during such period that may be required to maintain the same level of coverage. Executive

 (d) Impact of Change in Control. 

(i) If Executive’s employment is terminated by the Company without Cause or Executive resigns for Good Reason within three months prior
to, or within 12 months following, the consummation of a Change in Control of the Company, Executive shall be entitled to receive the Accrued Compensation and the additional payments and benefits set forth in Section 5(c) hereof on the same
terms and conditions, including the execution and effectiveness of the Release by the Release Deadline, provided that all Equity Awards subject to time-based vesting then held by Executive shall vest with respect to 100% of the shares underlying
such Equity Awards with such additional acceleration effective on the Release Deadline following the later of such termination or the consummation of the Change in Control. 

(ii) In the event that the payments and other benefits provided for in this Agreement or otherwise payable to Executive constitute
“parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”) and would be subject to the excise tax imposed by Section 4999 of the Code (the
“Excise Tax”), Executive’s payments and benefits under this Agreement shall be either (A) delivered in full or (B) delivered as to such lesser extent as would result in no portion of such payments and 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 Executive on an after-tax
basis of the greatest amount of payments and benefits, notwithstanding that all or some portion of such payments and benefits may be taxable under Section 4999 of the Code. 

(iii) Unless the Company and Executive otherwise agree in writing, any determination required under subsection (ii) above shall be made
in writing by the Company’s independent public accountants (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 5(d)(iii), 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 such determination. The Company shall bear all costs the Accountants may reasonably incur
in connection with any calculations contemplated by this Section 5(d)(iii). Any reduction in payments or benefits required by this Section 5(d)(iii) shall occur in a manner necessary to provide Executive with the greatest economic benefit.
If more than one manner of reduction of payments or benefits yields the greatest economic benefit, the payments and benefits shall be reduced pro rata, provided that the reduction shall be applied first to any payments or benefits that are not
subject to Section 409A and then shall be applied to payments or benefits (if any) that are subject to Section 409A, with the payments or benefits payable latest in time subject to reduction first. To the extent required to avoid a
violation of Section 409A of the Code, in no event shall the Company or Executive exercise any discretion with respect to the ordering of any reduction of payments or benefits pursuant to this Section 5(d)(iii).

 (e) Definitions. For purposes of this Agreement: 

(i) “Cause” shall mean the good faith determination by the Board that one of the following events has occurred following the
Effective Date: (A) conviction of, or plea of nolo contendere to, any felony or crime of moral turpitude; (B) act of fraud, theft or embezzlement with respect to the Company; (C) willful failure to substantially perform his duties or
comply with lawful Company policies or Board instructions (other than as a result of Executive’s mental or physical disability) that causes material harm to the Company (after written notice thereof and a reasonable opportunity to remedy such
failure); (D) willful breach of fiduciary duty that causes material harm to the Company; or (E) willful and material breach of this Agreement or the PIIA (after written notice thereof and a reasonable opportunity to remedy such breach). 

(ii) “Change in Control” shall be as defined in the Plan. 

(iii) “Disability” shall mean the inability of Executive, with reasonable accommodation, to perform the essential functions
of Executive’s position and duties for at least 180 consecutive days. 
 (iv) “Good Reason” shall mean any action by
the Company (or its successors or acquirers) that, without the written consent of Executive, results in any of the following, provided that Executive provides notice to the Company within ninety (90) days of the initial occurrence of any such
action, such action is not cured by the Company within thirty (30) days of such notice and Executive resigns within sixty (60) days following expiration of the cure period: (A) a material diminishment in Executive’s title,
authority, duties or responsibilities (other than a mere change in title following a Change in Control to a substantially similar position with a successor or acquirer); (B) a material reduction in Executive’s base compensation or target bonus;
(C) a material reduction in Executive’s participation in bonus, incentive or other benefit plans or programs or other action that materially and adversely affects Executive’s working conditions, in each case in a manner that affects
Executive disproportionately to that of other comparable executives; (D) following a Change in Control, a change in the principal work site of Executive by more than fifty (50) miles; (E) a material breach by the Company of the terms of
this Agreement or any Equity Award agreement after written notice thereof and a reasonable opportunity to remedy such breach; or (F) the failure of any successor or acquirer of the Company to assume the Company’s obligations under this
Agreement. 
 (f) Section 409A. 

(i) Payments and benefits under this Agreement are intended to be exempt from the definition of “nonqualified deferred compensation”
under Section 409A of the Code and the regulations promulgated thereunder (“Section 409A”) to the maximum extent possible. If any payments or benefits under this Agreement are or become subject to
Section 409A, the relevant provisions of this Agreement are intended to comply with the applicable requirements of Section 409A with respect to such payments or benefits and shall be interpreted and administered consistent with this
intent. 

  
 6 












 (ii) Each payment under this Agreement that is made in a series of scheduled installments
shall be deemed a separate payment for purposes of Section 409A. Executive’s date of termination for purposes of determining the date that any payment or benefit is to be paid under this Agreement, and for purposes of determining whether
Executive is a “Specified Employee” (within the meaning of Section 409A, as determined by the Company) on the date of termination, shall be the date on which Executive has incurred a “separation from service” within
the meaning of Section 409A. If any payment or benefit provided pursuant to this Agreement provides for a “deferral of compensation” within the meaning of Section 409A, (A) the amount of the payment or benefit provided
thereunder in any given calendar year shall not affect the amount of such payment or benefit provided in any other calendar year (except that a plan providing medical or health benefits may impose a generally applicable limit on the amount that may
be reimbursed or paid), (B) any portion of such payment or benefit provided in the form of a reimbursement shall be paid to Executive on or before the last day of the calendar year following the calendar year in which the expense was incurred, and
(C) such payment or benefit shall not be subject to liquidation or exchange for any other benefit. 
 (iii) Notwithstanding anything in
this Agreement or elsewhere to the contrary, if the Company is a public company on the date of Executive’s termination and Executive is a Specified Employee” (as determined by the Company) on such termination date, and the Company
reasonably determines that any payment or benefit under this Agreement on account of such separation from service, constitutes nonqualified deferred compensation that will subject Executive to “additional tax” under
Section 409A(a)(1)(B) of the Code (together with any interest or penalties imposed with respect to, or in connection with, such tax, a “409A Tax”) with respect to the payment of such amount or the provision of such benefit if
paid or provided at the time specified in the Agreement, then the payment or provision thereof shall be made (without interest) on the first business day of the seventh month following the date of termination or, if earlier, the date of
Executive’s death (the “Delayed Payment Date”). The Company and Executive may agree to take other actions to avoid the imposition of a 409A Tax at such time and in such manner as permitted under Section 409A. In the event
that this section requires a delay of any payment, such payment shall be accumulated and paid in a single lump sum (without interest) on the Delayed Payment Date. 

6. Miscellaneous. 
 (a)
Governing Law. This Agreement and the resolution of any dispute arising out of, related to, or in any way connected with, this Agreement, Executive’s employment with the Company or the termination of such employment shall be governed by

personal delivery, receipt signature in the case of overnight courier or confirmation of transmission in the case of facsimile or email. 

(e) Severability. In the event that any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be
illegal, unenforceable, or void, this Agreement shall continue in full force and effect without such provision. The remainder of this Agreement shall be interpreted so as best to effect the intent of the Company and Executive, and the parties shall
use their best efforts to find an alternative way to achieve the same result. 
 (f) Integration. This Agreement represents the entire
agreement and understanding between the parties as to the subject matter herein and supersedes, merges and voids all prior or contemporaneous agreements with respect to such subject matter, whether written or oral. 

(g) Amendments and Waivers. No amendment, modification or waiver of any of the provisions of this Agreement shall be binding unless in
writing and signed by Executive and by an authorized officer of the Company (other than Executive). No waiver by either party of any provision of this Agreement by the other party will be considered a waiver of any other provision or of the same
provision at another time.

counterpart shall have the same force and effect as an original and shall constitute an effective, binding agreement on the part of each of the undersigned.
