2015 Equity Incentive Plan 

Non-Statutory Stock Option Agreement 

Option Terms and Conditions 
  

	1.	Non-Statutory Stock Option. This Option is not intended to be an “incentive stock option” within the meaning of Section 422 of the Internal Revenue Code and will be interpreted
accordingly. 

  

	2.	Vesting and Exercisability of Option. 

 (a) Scheduled Vesting. This Option
will vest and become exercisable as to the number of Shares and on the dates specified in the Vesting and Exercise Schedule on the cover page to this Agreement, so long as your Service to the Company does not end. The Vesting and Exercise Schedule
is cumulative, meaning that to the extent the Option has not already been exercised and has not expired or been terminated or cancelled, you or the person otherwise entitled to exercise the Option as provided in this Agreement may at any time
purchase all or any portion of the Shares subject to the vested portion of the Option. 
 (b) Accelerated Vesting. [EXECUTIVES:
Notwithstanding Section 2(a), if and to the extent this Option is continued, assumed or replaced in connection with a Change in Control, and if within one year after such Change in Control you experience an involuntary termination of Service
for reasons other than Cause, then this Option (or any replacement award) shall immediately vest and become exercisable in full and shall remain exercisable for one year following your termination of Service. In addition, vesting and exercisability
of this Option may be accelerated during the term of the Option under the circumstances described in Sections 12(b) and 12(c) of the Plan, and at the discretion of the Committee in accordance with Section 3(b)(2) of the Plan.] [DIRECTORS:
Notwithstanding Section 2(a), this Option shall immediately vest and become exercisable in full as of or immediately prior to the effective time of a Change in Control.] [NON-EXECUTIVE EMPLOYEES: Vesting and exercisability of this Option may be
accelerated during the term of the Option under the circumstances described in Sections 12(b) and 12(c) of the Plan, and at the discretion of the Committee in accordance with Section 3(b)(2) of the Plan.] 

 

	3.	Expiration. This Option will expire and will no longer be exercisable at 5:00 p.m. Eastern Time on the earliest of: 


 

	 	(a)	The expiration date specified on the cover page of this Agreement; 

  

	 	(b)	Upon your termination of Service for Cause; 

  

	 	(c)	Upon the expiration of any applicable period specified in Section 6(e) of the Plan or Section 2 of this Agreement during which this Option may be exercised after your termination of Service; or


  

	 	(d)	The date (if any) fixed for termination or cancellation of this Option pursuant to Section 12 of the Plan. 

  

	4.	Service Requirement. Except as otherwise provided in Section 6(e) of the Plan or Section 2 of this Agreement, this Option may be exercised only while you continue to provide Service to the
Company or any Affiliate, and only if you have continuously provided such Service since the Grant Date of this Option.

	5.	Exercise of Option. Subject to Section 4, the vested and exercisable portion of this Option may be exercised in whole or in part at any time during the Option term by delivering a written or
electronic notice of exercise to the Company’s Chief Financial Officer at the Company’s principal executive office, and by providing for payment of the exercise price of the Shares being acquired and any related withholding taxes. The
notice of exercise must be in a form approved by the Company and state the number of Shares to be purchased, the method of payment of the aggregate exercise price and the directions for the delivery of the Shares to be acquired, and must be signed
or otherwise authenticated by the person exercising the Option. If you are not the person exercising the Option, the person submitting the notice also must submit appropriate proof of his/her right to exercise the Option. 


 

	6.	Payment of Exercise Price. When you submit your notice of exercise, you must include payment of the exercise price of the Shares being purchased through one or a combination of the following methods:


  

	 	(a)	Cash (including personal check, cashier’s check or money order); 

  

	 	(b)	By means of a broker-assisted cashless exercise in which you irrevocably instruct your broker to deliver proceeds of a sale of all or a portion of the Shares to be issued pursuant to the exercise to the Company in
payment of the exercise price of such Shares; or 

  

	 	(c)	By delivery to the Company of Shares (by actual delivery or attestation of ownership in a form approved by the Company) already owned by you that are not subject to any security interest and that have an aggregate Fair
Market Value on the date of exercise equal to the exercise price of the Shares being purchased; or 

  

	 	(d)	By authorizing the Company to retain, from the total number of Shares as to which the Option is being exercised, that number of Shares having a Fair Market Value on the date of exercise equal to the exercise price for
the total number of Shares as to which the Option is being exercised. 

 However, if the Committee determines, in any given
circumstance, that payment of the exercise price with Shares or by authorizing the Company to retain Shares is undesirable for any reason, you will not be permitted to pay any portion of the exercise price in that manner. 

 

	7.	Withholding Taxes. Delivery of Shares upon exercise of this Option is subject to the satisfaction of applicable withholding tax obligations, and you agree to satisfy such obligations in accordance with the
provisions of Section 14 of the Plan. The Company will retain that portion of the Shares being acquired upon exercise of the Option having a Fair Market Value equal to the amount required to be withheld, unless you provide notice to the Company
as part of your exercise notice that you desire to pay cash or to deliver Shares you already own having a Fair Market Value equal to the amount required to be withheld to satisfy all applicable tax withholding requirements and you make such cash or
Shares (along with fully executed transfer documents) available to the Company on or before the exercise date. The Fair Market Value of any Shares to be withheld or delivered will be determined as of the date that the taxes are required to be
withheld. 

  

	8.	 Delivery of Shares. As soon as practicable after the Company receives the notice of exercise and payment of the exercise price as
provided above, and has determined that all other conditions to 



  

			
	Non-Statutory Stock Option Agreement (2015 Equity Incentive Plan)		Page 3










	 	
exercise, including satisfaction of withholding tax obligations and compliance with applicable laws as provided in Section 18(c) of the Plan, have been satisfied, it shall deliver to the
person exercising the Option, in the name of such person, the Shares being purchased, as evidenced by issuance of a stock certificate or certificates, electronic delivery of such Shares to a brokerage account designated by such person, or book-entry
registration of such Shares with the Company’s transfer agent. The Company shall pay any original issue or transfer taxes with respect to the issue or transfer of the Shares and all fees and expenses incurred by it in connection therewith. All
Shares so issued shall be fully paid and nonassessable. 

  

	9.	Transfer of Option. During your lifetime, only you (or your guardian or legal representative in the event of legal incapacity) may exercise this Option except in the case of a transfer described below. You
may not assign or transfer this Option except (i) for a transfer upon your death in accordance with your will, by the laws of descent and distribution or pursuant to a beneficiary designation submitted in accordance with Section 6(d) of
the Plan, (ii) pursuant to a domestic relations order, or (iii) with the prior written approval of the Company, by gift, in a form accepted by the Company, to a permitted transferee under General Instruction A(5) to Form S-8 under the
Securities Act. The Option held by any such transferee will continue to be subject to the same terms and conditions that were applicable to the Option immediately prior to its transfer and may be exercised by such transferee as and to the extent
that the Option has become exercisable and has not terminated in accordance with the provisions of the Plan and this Agreement. 

  

	10.	No Stockholder Rights Before Exercise. Neither you nor any permitted transferee of this Option will have any of the rights of a stockholder of the Company with respect to any Shares subject to this Option
until a certificate evidencing such Shares has been issued, electronic delivery of such Shares has been made to your designated brokerage account, or an appropriate book entry in the Company’s stock register has been made. No adjustments shall
be made for dividends or other rights if the applicable record date occurs before your stock certificate has been issued, electronic delivery of your Shares has been made to your designated brokerage account, or an appropriate book entry in the
Company’s stock register has been made, except as otherwise described in the Plan. 

  

	11.	Governing Plan Document. This Agreement and Option are subject to all the provisions of the Plan, and to all interpretations, rules and regulations which may, from time to time, be adopted and promulgated
by the Committee pursuant to the Plan. If there is any conflict between the provisions of this Agreement and the Plan, the provisions of the Plan will govern. 

  

	12.	Choice of Law. This Agreement will be interpreted and enforced under the laws of the state of Delaware (without regard to its conflicts or choice of law principles). 


 

	13.	Binding Effect. This Agreement will be binding in all respects on your heirs, representatives, successors and assigns, and on the successors and assigns of the Company. 


 

	14.	Other Agreements. You agree that in connection with the exercise of this Option, you will execute such documents as may be necessary to become a party to any stockholder, voting or similar agreements as
the Company may require. 

  

	15.	Restrictive Legends. The Company may place a legend or legends on any certificate representing Shares issued upon the exercise of this Option summarizing transfer and other restrictions to which the Shares
may be subject under applicable securities laws, other provisions of this Agreement, or other agreements contemplated by Section 14 of this Agreement. You agree that in order to ensure compliance with the restrictions referred to in this
Agreement, the Company may issue appropriate “stop transfer” instructions to its transfer agent.

	16.	Compensation Recovery Policy. To the extent that any compensation paid or payable pursuant to this Agreement is considered “incentive-based compensation” within the meaning and subject to the
requirements of Section 10D of the Exchange Act, such compensation shall be subject to potential forfeiture or recovery by the Company in accordance with any compensation recovery policy adopted by the Board of Directors of the Company or any
committee thereof in response to the requirements of Section 10D of the Exchange Act and any implementing rules and regulations thereunder adopted by the Securities and Exchange Commission or any national securities exchange on which the
Company’s common stock is then listed. This Agreement may be unilaterally amended by the Company to comply with any such compensation recovery policy.

  

	17.	Electronic Delivery and Acceptance. The Company may deliver any documents related to this Option Award by electronic means and request your acceptance of this Agreement by electronic means. You hereby
consent to receive all applicable documentation by electronic delivery and to participate in the Plan through an on-line (and/or voice activated) system established and maintained by the Company or the Company’s third-party stock plan
administrator.
