 RESTRICTED STOCK UNIT AGREEMENT 
 RECITALS 
 A. The Board has adopted the Plan
for the purpose of attracting and retaining the best available personnel, to provide additional incentive to eligible employees, consultants and directors and to promote the success of the Company’s business. 
 B. Participant is to render valuable services to the Company (or a Parent or Subsidiary), and this Agreement is executed pursuant to, and is intended to
carry out the purposes of, the Plan in connection with the Company’s issuance of shares of Common Stock to Participant under the Plan. 
 C. All capitalized terms in this Agreement shall have the meaning assigned to them in the attached Appendix A. 
 NOW, THEREFORE, it is
hereby agreed as follows: 
 1. Grant of Restricted Stock Units. The Company hereby grants to Participant, as of the
Award Date, restricted stock units under the Plan (the “Award”). Each restricted stock unit represents the right to receive one share of Common Stock on the specified issuance date following the vesting of that unit. The number of shares
of Common Stock subject to the Award, the applicable vesting schedule for those shares, the date on which those vested shares shall become issuable to Participant and the remaining terms and conditions governing the Award shall be as set forth in
this Agreement. 
 AWARD SUMMARY 
  

			
	Award Date:	  	                                ,
200    
		
	Number of Shares
Subject to Award:	  	                     shares of Common Stock (the “Shares”)
		
	Vesting Schedule:	  	 Vice Presidents, Principal Engineers and managers at Director level and above:
  
 The Shares shall vest as follows provided Participant remains in Continuous Status as an Employee,
Consultant or Director through each vesting date:
  
 (i) Fifty percent
(50%) of the Shares shall vest on the second anniversary of the Award Date,
  
 (ii) Twenty-five percent (25%) of the Shares shall vest on the third anniversary of the Award Date, and










			
		  	 (iii) Twenty-five percent (25%) of the Shares shall vest on the fourth anniversary of the Award Date.
  
 For All Other Employees:
  
 The Shares shall vest in a series of four (4) successive equal annual installments upon each of the
first four anniversaries of the Award Date provided Participant remains in Continuous Status as an Employee, Consultant or Director through each such date.
  
 For members of the Company’s Board of Directors in connection with their annual award:
  
 All of the Shares shall vest on the one (1) year anniversary of the Award Date, provided Participant
remains in Continuous Status as an Employee, Consultant or Director through each such date.
  
 For members of the Company’s Board of Directors if elect to receive equity in lieu of annual cash compensation:
  
 All of the Shares shall vest immediately on the grant date.

		
	Issuance Schedule:	  	The Shares in which Participant vests in accordance with the foregoing Vesting Schedule shall be issued upon vesting or as soon as administratively practicable thereafter, but in no event
later than the close of the calendar year in which such vesting occurs, or (if later) the fifteenth (15th) day of the third (3rd) calendar month following such vesting. The actual issuance of the Shares shall be subject to the Company’s
collection of all applicable Withholding Taxes in accordance with Paragraph 6 of this Agreement. In no event, however, shall any fractional shares be issued. Accordingly, the total number of shares of Common Stock to be issued pursuant to the Award
shall, to the extent necessary, be rounded down to the next whole share in order to avoid the issuance of a fractional share.

 2. Cessation of Employment or Service. Should Participant’s Continuous Status
as an Employee, Consultant or Director cease for any reason prior to vesting in one or more Shares subject to this Award, then the Award will be immediately cancelled with respect to those unvested Shares. Participant shall thereupon cease to have
any right or entitlement to receive any Shares under those cancelled units. 
 3. Limited Transferability. Prior to the actual
issuance of the Shares which vest hereunder, Participant may not transfer any interest in the Award or the underlying Shares; provided, however, any Shares which vest hereunder but which otherwise remain unissued at the time of
Participant’s death may be transferred (subject to applicable law) pursuant to the provisions of Participant’s will or the laws of descent or distribution. 
  

 2 








 4. Stockholder Rights. The holder of this Award shall not have any stockholder rights,
including voting or dividend rights, with respect to the Shares subject to the Award until Participant becomes the record holder of those Shares following their actual issuance upon the Company’s collection of the applicable Withholding Taxes.

 5. Adjustment in Shares. In the event of any increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company
(other than a conversion of any convertible securities of the Company) then the number of Shares subject to this Award shall be adjusted proportionately by the Board. 
 6. Collection of Withholding Taxes. 
 (a) Until such time as the Company provides Participant
with written or electronic notice to the contrary, the Company shall collect the Withholding Taxes required to be withheld with respect to the issuance of the vested Shares hereunder through an automatic share withholding procedure pursuant to which
the Company will withhold, at the time of such issuance, a portion of the Shares with a Fair Market Value (measured as of the issuance date) equal to the amount of those taxes (the “Share Withholding Method”); provided, however, that the
amount of any Shares so withheld shall not exceed the minimum statutory amount required to be withheld by the Company. Notwithstanding the foregoing, the Administrator may, at its sole discretion, require that such Withholding Taxes be paid through
one of the following methods selected by the Administrator in lieu of the Share Withholding Method: 
 (ii) Participant’s
delivery of his or her separate check payable to the Company in the amount of such taxes, or 
 (iii) the use of the proceeds
from a next-day sale of the Shares issued to Participant, provided and only if (A) such a sale is permissible under the Company’s trading policies governing the sale of Common Stock, (B) Participant makes an irrevocable commitment, on
or before the issuance date for those Shares, to effect such sale of the Shares and (C) the transaction is not otherwise deemed to constitute a prohibited loan under Section 402 of the Sarbanes-Oxley Act of 2002. 
 (b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 6, the employee portion of any U.S. federal, state and local employment
taxes and any foreign taxes or payments required to be withheld by the Company in connection with the vesting of the Shares (the “Employment Taxes”) shall in all events be collected from Participant no later than the last business day of
the calendar year in which the Shares vest hereunder. Accordingly, to the extent the issuance date for one or more vested Shares is to occur in a year subsequent to the calendar year in which those Shares vest, Participant shall, on or before the
last 

  

 3 








 
business day of the calendar year in which the Shares vest (or at such time as determined by the Company), deliver to the Company a check payable to its
order in the dollar amount equal to the Employment Taxes required to be withheld with respect to those Shares. 
 7. Compliance with
Laws and Regulations. The issuance of shares of Common Stock pursuant to the Award shall be subject to compliance by the Company and Participant with all applicable requirements of law relating thereto and with all applicable regulations of
any stock exchange on which the Common Stock may be listed for trading at the time of such issuance. 
 8. Notices. Any notice
required to be given or delivered to the Company under the terms of this Agreement shall be in writing and addressed to the Company at its principal corporate offices. Except to the extent electronic notice is expressly authorized hereunder, any
notice required to be given or delivered to Participant shall be in writing and addressed to Participant at the address indicated below Participant’s signature line on this Agreement. All notices shall be deemed effective upon personal delivery
(or electronic delivery to the extent authorized hereunder) or upon deposit in the U.S. mail, postage prepaid and properly addressed to the party to be notified. 
 9. Successors and Assigns. Except to the extent otherwise provided in this Agreement, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the Company and its successors
and assigns and Participant, Participant’s assigns and the legal representatives, heirs and legatees of Participant’s estate. 
 10. Construction. This Agreement and the Award evidenced hereby are made and granted pursuant to the Plan and are in all respects limited by and subject to the terms of the Plan. All decisions of the Administrator with respect
to any question or issue arising under the Plan or this Agreement shall be conclusive and binding on all persons having an interest in the Award. 
 11. Governing Law. The interpretation, performance and enforcement of this Agreement shall be governed by the laws of the State of Delaware without resort to that State’s conflict-of-laws rules. 
 12. Employment at Will. Nothing in this Agreement or in the Plan shall confer upon Participant any right to continue in employment or
service for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Company (or any Parent or Subsidiary employing or retaining Participant) or of Participant, which rights are hereby expressly reserved
by each, to terminate Participant’s Continuous Status as an Employee, Consultant or Director at any time for any reason, with or without cause, subject to applicable law and the terms of any employment agreement. 
 13. Nature of Grant; No Entitlement; No claim for Compensation. In accepting the grant of this Award for the number of Shares as specified
above, Participant acknowledges the following: 
 (a) The Plan and any sub-plans and addenda thereto are established voluntarily by the
Company, they are discretionary in nature and may be modified, amended, suspended or terminated by the Company at any time. 
  

 4 








 (b) The grant of this Award is voluntary and occasional and does not create any contractual or other
right to receive future grants of awards, or benefits in lieu of awards, even if awards have been granted repeatedly in the past. 
 (c) All
decisions with respect to future awards, if any, will be at the sole discretion of the Administrator. 
 (d) Participant is voluntarily
participating in the Plan. 
 (e) This Award is an extraordinary item that does not constitute compensation of any kind for services of any
kind rendered to the Company or its Parent or Subsidiaries (including, as applicable, Participant’s employer) and which is outside the scope of Participant’s employment contract, if any. 
 (f) This Award is not part of normal or expected compensation or salary for any purpose, including, but not limited to, calculating any severance,
resignation, termination, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments. 
 (g) In the event that Participant’s employer is not the Company, the grant of the Award will not be interpreted to form an employment contract or relationship with the Company and, furthermore, the grant of the Award will not be
interpreted to form an employment contract with Participant’s employer or any Parent or Subsidiary. 
 (h) The future value of the
underlying Shares is unknown and cannot be predicted with certainty. 
 (i) In consideration of the grant of this Award, no claim or
entitlement to compensation or damages shall arise from termination of the Award or diminution in value of the Award or any of the Shares issuable under the Award from termination of Participant’s employment by the Company or Participant’s
employer, as applicable (and for any reason whatsoever and whether or not in breach of contract or local labor laws), and Participant irrevocably releases his or her employer, the Company and its Subsidiaries, as applicable, from any such claim that
may arise; if, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have arisen, then, by signing this Agreement, Participant shall be deemed to have irrevocably waived his or her entitlement to pursue such
claim. 
 14. Data Privacy. 
 (a) Participant hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of Participant’s personal data as described in this Agreement by and among, as
applicable, Participant’s employer, the Company and its Parent and Subsidiaries for the exclusive purpose of implementing, administering and managing Participant’s participation in the Plan. 
  

 5

Subsidiaries, as applicable, hold certain personal information about Participant regarding Participant’s employment, the nature and amount of Participant’s compensation and the fact and conditions of Participant’s participation in the
Plan, including, but not limited to, Participant’s name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, health, job title, any shares of stock or directorships held

of the Data, require any necessary amendments to the Data or refuse or withdraw the consents herein, in any case without cost, by contacting in writing Participant’s local human resources representative. Participant understands, however, that
