STOCK AWARD AGREEMENT 

TERMS AND CONDITIONS OF STOCK AWARD 

1. Grant of Shares. The Company hereby grants to the individual (the “Participant”) named in the Notice of Stock Grant of
this Award Agreement (the “Notice of Grant”) under the Plan an Award of fully vested Shares, subject to all of the terms and conditions in this Award Agreement and the Plan, which is incorporated herein by reference. Subject to Section
19(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and this Award Agreement, the terms and conditions of the Plan shall prevail. 

2. Vesting Schedule. The Shares awarded by this Award Agreement will be fully vested on the Date of Grant. 

3. Tax Consequences. Participant has reviewed with its own tax advisors the U.S. federal, state, local and foreign tax consequences of
this investment and the transactions contemplated by this Award Agreement. With respect to such matters, Participant relies solely on such advisors and not on any statements or representations of the Company or any of its agents, written or oral.
Participant understands that Participant (and not the Company) shall be responsible for Participant’s own tax liability that may arise as a result of this investment or the transactions contemplated by this Award Agreement. 

4. Tax Obligations. Participant acknowledges that, regardless of any action taken by the Company, the ultimate liability for any
tax and/or social insurance liability obligations and requirements in connection with the Shares awarded by to this Award Agreement, including, without limitation, (a) all federal, state, and local taxes (including the Participant’s Federal
Insurance Contributions Act (FICA) obligation) that are required to be withheld by the Company or other payment of tax-related items related to Participant’s participation in the Plan and legally applicable to Participant, (b) the
Participant’s and, to the extent required by the Company, the Company’s fringe benefit tax liability, if any, associated with the grant of Shares or sale of Shares, and (c) any other Company taxes the responsibility for which the
Participant has, or has agreed to bear, with respect to the Shares (collectively, the “Tax Obligations”), is and remains Participant’s responsibility and may exceed the amount actually withheld by the Company. Participant further
acknowledges that the Company (i) make no representations or undertakings regarding the treatment of any Tax Obligations in connection with any aspect of the Shares awarded by this Award Agreement, including, but not limited to, the grant of the
Shares, the subsequent sale of Shares and the receipt of any dividends or other distributions, and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Shares to reduce or eliminate
Participant’s liability for Tax Obligations or achieve any particular tax result. Further, if Participant is subject to Tax Obligations in more than one jurisdiction between the Date of Grant and the date of any relevant taxable or tax
withholding event, as applicable, Participant acknowledges that the Company may be required to withhold or account for Tax Obligations in more than one jurisdiction. If Participant fails to make satisfactory arrangements for the payment of any
required Tax Obligations hereunder at the time of the applicable taxable event, Participant acknowledges and 







 
agrees that the Company may refuse to issue or deliver the Shares awarded by this Award Agreement. If Participant fails to make satisfactory arrangements for the payment of such Tax
Obligations hereunder, Participant will permanently forfeit the Shares awarded by this Award Agreement and the Shares will be returned to the Company at no cost to the Company.

5. Rights as Stockholder. Neither Participant nor any person claiming under or through Participant will have any of the rights or
privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares (which may be in book entry form) will have been issued, recorded on the records of the Company or its
transfer agents or registrars, and delivered to Participant (including through electronic delivery to a brokerage account). After such issuance, recordation and delivery, Participant will have all the rights of a stockholder of the Company with
respect to voting such Shares and receipt of dividends and distributions on such Shares. 
 6. No Guarantee of Continued Service.
PARTICIPANT ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREUNDER DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR ANY PERIOD OR AT ALL, AND SHALL NOT INTERFERE IN
ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. 

7. Nature of Grant. In accepting the grant, Participant acknowledges, understands and agrees that: 

(a) the grant of the Shares awarded by this Award Agreement is voluntary and occasional and does not create any contractual or other right to
receive future grants of Shares, or benefits in lieu of Shares, even if Shares have been granted in the past; 
 (b) all decisions with
respect to future Awards of Shares or other grants, if any, will be at the sole discretion of the Company; 
 (c) Participant is voluntarily
participating in the Plan; 
 (d) the Shares are not intended to replace any pension rights or compensation; 

(e) the Shares awarded by this Award Agreement and the income and value of same, are not part of normal or expected compensation for purposes
of calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments; 

(f) the future value of the Shares is unknown, indeterminable and cannot be predicted; 

(g) unless otherwise provided in the Plan or by the Company in its discretion, the Shares and the benefits evidenced by this Award Agreement
do not create any entitlement to have the Shares or any such benefits transferred to, or assumed by, another company nor be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the Shares; and 







 (h) the following provisions apply only if Participant is providing services outside the United
States: 
  

	 	(i)	the Shares awarded by this Award Agreement are not part of normal or expected compensation or salary for any purpose; 

  

	 	(ii)	Participant acknowledges and agrees that none of the Company or any Parent or Subsidiary shall be liable for any foreign exchange rate fluctuation between Participant’s local currency and the United States
Dollar that may affect the value of the Shares awarded by this Award Agreement or the subsequent sale of the Shares; and 

  

	 	(iii)	In consideration of the grant of the Shares awarded by this Award Agreement to which Participant is otherwise not entitled, Participant irrevocably agrees never to institute any claim against the Company, any
Parent or Subsidiary waives his or her ability, if any, to bring any such claim, and releases the Company, any Parent or Subsidiary from any such claim; if, notwithstanding the foregoing, any such claim is allowed by a court of competent
jurisdiction, then, by participating in the Plan, Participant shall be deemed irrevocably to have agreed not to pursue such claim and agrees to execute any and all documents necessary to request dismissal or withdrawal of such claim.


 8. No Advice Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the Company
making any recommendations regarding Participant’s participation in the Plan, or Participant’s acquisition or sale of the underlying Shares. Participant is hereby advised to consult with his or her own personal tax, legal and financial
advisors regarding his or her participation in the Plan before taking any action related to the Plan. 
 9. Data
Privacy. 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 Award Agreement and any other
Share grant materials by and among, as applicable, the Company and any Parent or Subsidiary for the exclusive purpose of implementing, administering and managing Participant’s participation in the Plan. 

Participant understands that the Company may hold certain personal information about Participant, 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, job title, any Shares or directorships held in the Company, details of all Shares or any other
entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in Participant’s favor (“Data”), for the exclusive purpose of implementing, administering and managing the Plan. 







 Participant understands that Data will be transferred to a stock plan service provider as
may be selected by the Company in the future, which is assisting the Company with the implementation, administration and management of the Plan. Participant understands that the recipients of the Data may be located in the United States or
elsewhere, and that the recipients’ country of operation (e.g., the United States) may have different data privacy laws and protections than Participant’s country. Participant understands that if he or she resides outside the United
States, he or she may request a list with the names and addresses of any potential recipients of the Data by contacting his or her local human resources representative. Participant authorizes the Company, any stock plan service provider selected by
the Company and any other possible recipients which may assist the Company (presently or in the future) with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for
the sole purpose of implementing, administering and managing his or her participation in the Plan. Participant understands that Data will be held only as long as is necessary to implement, administer and manage Participant’s participation in
the Plan. Participant understands if he or she resides outside the United States, he or she may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or
withdraw the consents herein, in any case without cost, by contacting in writing his or her local human resources representative. Further, Participant understands that he or she is providing the consents herein on a purely voluntary basis. If
Participant does not consent, or if Participant later seeks to revoke his or her consent, his or her status as a Service Provider and career with the Company will not be adversely affected; the only adverse consequence of refusing or withdrawing
Participant’s consent is that the Company would not be able to grant Participant Shares or other equity awards or administer or maintain such awards. Therefore, Participant understands that refusing or withdrawing his or her consent may affect
Participant’s ability to participate in the Plan. For more information on the consequences of Participant’s refusal to consent or withdrawal of consent, Participant understands that he or she may contact his or her local human resources
representative.

electronic delivery and agrees to participate in the Plan through any on-line or electronic system established and maintained by the Company or another third party designated by the Company. 

12. No Waiver. Either party’s failure to enforce any provision or provisions of this Agreement shall not in any way be construed
as a waiver of any such provision or provisions, nor prevent that party from thereafter enforcing each and every other provision of this Agreement. The rights granted both parties herein are cumulative and shall not constitute a waiver of either
party’s right to assert all other legal remedies available to it under the circumstances. 







 13. Successors and Assigns. The Company may assign any of its rights under this
Agreement to single or multiple assignees, and this Agreement shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Agreement shall be binding upon Participant

14. Additional Conditions to Issuance of Stock. If at any time the Company will determine, in its discretion, that the listing,
registration, qualification or rule compliance of the Shares upon any securities exchange or under any state, federal or foreign law, the tax code and related regulations or under the rulings or regulations of the United States Securities and
Exchange Commission or any other governmental regulatory body or the clearance, consent or approval of the United States Securities and Exchange Commission or any other governmental regulatory authority is necessary or desirable as a condition to
the issuance of Shares to Participant (or his or her estate) hereunder, such issuance will not occur unless and until such listing, registration, qualification, rule compliance, clearance, consent or approval will have been completed, effected or
obtained free of any conditions not acceptable to the Company. Subject to the terms of the Agreement and the Plan, the Company shall not be required to issue any certificate or certificates for Shares hereunder prior to the lapse of such
reasonable period of time following the Date of Grant of the Shares as the Administrator may establish from time to time for reasons of administrative convenience.

other than English and if the meaning of the translated version is different than the English version, the English version will control.

for the administration, interpretation and application of the Plan as are consistent therewith and to interpret or revoke any such rules. All actions taken and all interpretations and determinations made by the Administrator in good faith will
be final and binding upon Participant, the Company and all other interested persons. Neither the Administrator nor any person acting on behalf of the Administrator will be personally liable for any action, determination or interpretation made
in good faith with respect to the Plan or this Award Agreement.

representations, or inducements other than those contained herein. Modifications to this Award Agreement or the Plan can be made only in an express written contract executed by a duly authorized officer of the Company. Notwithstanding
anything to the contrary in the Plan or this Award Agreement, the Company reserves the right to revise this Award Agreement as it deems necessary or advisable, in its sole discretion and without the consent of Participant, to comply with Section

20. Agreement Severable. In the event that any provision in this Award Agreement will be held invalid or unenforceable, such
provision will be severable from, and such invalidity or unenforceability will not be construed to have any effect on, the remaining provisions of this Award Agreement.

RESTRICTED STOCK UNIT AGREEMENT 

COUNTRY ADDENDUM 
 TERMS AND
CONDITIONS 
 This Country Addendum includes additional terms and conditions that govern the award of Shares under the Plan if Participant works in
one of the countries listed below. If Participant is a citizen or resident of a country (or is considered as such for local law purposes) other than the one in which he or she is currently working or if Participant relocates to another country
after receiving the Award of Shares, the Company will, in its discretion, determine the extent to which the terms and conditions contained herein will be applicable to Participant. 

Certain capitalized terms used but not defined in this Country Addendum shall have the meanings set forth in the Plan and/or the Award Agreement to which this
Country Addendum is attached. 
 NOTIFICATIONS 

This Country Addendum also includes notifications relating to exchange control and other issues of which Participant should be aware with respect to his or her
participation in the Plan. The information is based on the exchange control, securities and other laws in effect in the countries listed in this Country Addendum, as of [DATE]. Such laws are often complex and change frequently. As a
result, the Company strongly recommends that Participant not rely on the notifications herein as the only source of information relating to the consequences of his or her participation in the Plan because the information may be outdated when
Participant subsequently sell Shares acquired under the Plan. 
 In addition, the notifications are general in nature and may not apply to
Participant’s particular situation, and the Company is not in a position to assure Participant of any particular result. Accordingly, Participant is advised to seek appropriate professional advice as to how the relevant laws in
Participant’s country may apply to Participant’s situation. 
 Finally, if Participant is a citizen or resident of a country other than the one in
which Participant is currently working (or is considered as such for local law purposes) or if Participant moves to another country after receiving an Award of Shares, the information contained herein may not be applicable to Participant.
