(c) Other legal consideration acceptable to the Administrator (including, without limitation, through the delivery of a notice that Participant has placed a market sell order with a broker with respect to Shares then issuable upon exercise of the Option, and that the broker has been directed to pay a sufficient portion of the net proceeds of the sale to the Company in satisfaction of the Option exercise price; provided that payment of such proceeds is then made to the Company at such time as may be required by the Company, but in any event not later than the settlement of such sale).

4.5 Conditions to Issuance of Shares. The Shares deliverable upon the exercise of the Option, or any portion thereof, may be either previously authorized but unissued Shares or issued Shares which have then been reacquired by the Company. Such Shares shall be fully paid and nonassessable. The Company shall not be required to issue or deliver any Shares purchased upon the exercise of the Option or portion thereof prior to fulfillment of all of the conditions in Section 10.7 of the Plan.

4.6 Participant’s Representations. If the Shares issuable hereunder have not been registered under the Securities Act or any applicable state laws on an effective registration statement at the time of exercise, Participant shall, if required by the Company, concurrently with such exercise, make such written representations as are deemed necessary or appropriate by the Company or its counsel.

4.7 Rights as Stockholder.

5.18 Limitation on Participant’s Rights. Participation in the Plan confers no rights or interests other than as herein provided. This Agreement creates only a contractual obligation on the part of the Company as to amounts payable and shall not be construed as creating a trust. Neither the Plan nor any underlying program, in and of itself, has any assets. Participant shall have only the rights of a general unsecured creditor of the Company and its Subsidiaries with respect to amounts credited and benefits payable, if any, with respect to the Option, and rights no greater than the right to receive the Shares as a general unsecured creditor with respect to the Option, as and when exercised pursuant to the terms hereof.

A-7

that the application of such provisions is necessary or advisable in order to comply with local law or facilitate the administration of the Plan.

APPENDIX

TO

STOCK OPTION AGREEMENT

Special Country Provisions for Options for Participants

This Appendix includes special terms and conditions applicable to Participants in the countries below. These terms and conditions are in addition to those set forth in the Stock Option Agreement (the “Agreement”) and the Plan, and to the extent there are any inconsistencies between these terms and conditions and those set forth in the Agreement, these terms and conditions shall prevail. Any capitalized term used in this Appendix without definition shall have the meaning ascribed to such term in the Plan or the Agreement, as applicable.

In accepting the Option, Participant acknowledges, understands and agrees that:

(a) the Plan is established voluntarily by the Company, it is discretionary in nature, and may be amended, suspended or terminated by the Company at any time, to the extent permitted by the Plan;

(b) the grant of the Option is voluntary and occasional and does not create any contractual or other right to receive future grants of options, or benefits in lieu of options, even if options have been granted in the past;

(c) all decisions with respect to future option or other grants, if any, will be at the sole discretion of the Company;

(d) the Option grant and Participant’s participation in the Plan shall not create a right to employment or be interpreted as forming an employment or service contract with the Company, or, if different, Participant’s employer, or any Subsidiary or parent or affiliate of the Company, and shall not interfere with the ability of the Company, the employer or any Subsidiary or parent or affiliate of the Company, as applicable, to provide for a termination of Participant’s service;

(e) Participant is voluntarily participating in the Plan;

(f) the Option and any Shares acquired under the Plan are not intended to replace any pension rights or compensation;

(g) the Option and any Shares acquired under the Plan and the income and value of same, are not part of normal or expected compensation for any purpose, including, without limitation, calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments;

(h) the future value of the Shares underlying the Option is unknown, indeterminable, and cannot be predicted with certainty;

(i) if the underlying Shares do not increase in value, the Option will have no value;

Securities Law Notice: Unless otherwise noted, neither the Company nor the Shares are registered with any local stock exchange or under the control of any local securities regulator outside the United States. The Agreement (of which this Appendix is a part), the Plan, and any other communications or materials that Participant may receive regarding participation in the Plan do not constitute advertising or an offering of securities outside the United States, and the issuance of securities described in any Plan-related documents is not intended for public offering or circulation in Participant’s jurisdiction.

General Provisions

Data Privacy: Participant acknowledges and agrees to the data privacy provisions set forth in Section 11.8 of the Plan.

Notifications: This Appendix also includes information 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 respective countries as of [____________], 2021. Such laws are often complex and change frequently. As a result, the Company strongly recommends that Participant not rely on the information herein as the only source of information relating to the consequences of participation in the Plan because the information may be out of date at the time the Option is exercised or Shares acquired under the Plan are sold. In addition, the information contained in this Appendix is 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 his or her country may apply to his or her situation. Finally, Participant understands that if Participant is a citizen or resident of a country other than the one in which he or she is currently residing or working, the information contained herein may not be applicable to Participant.

English Language: By participating in the Plan, Participant acknowledges that Participant is proficient in the English language, or has consulted with an advisor who is sufficiently proficient in English, so as to allow him or her to understand the terms and conditions of the Plan and the Agreement applicable to Participant’s country of residence. If Participant has received the Agreement and the Plan applicably to his or her country of residence or any other document related to the Plan translated into a language other than English and if the meaning of the translated version is different than the English version, the English version will control.

Currency: Participant understands that, any amounts related to the Option will be denominated in U.S. dollars and will be converted to any local currency using a prevailing exchange rate in effect at the time such conversion is performed, as determined by the Company. Participant understands and agrees that neither the Company nor any affiliate shall be liable for any foreign exchange rate fluctuation between Participant’s local currency and the U.S. dollar that may affect the value of the Option, or of any amounts due to Participant or as a result of the subsequent sale of any Shares acquired under the Option.

Foreign Asset/Account Reporting; Exchange Controls: Participant’s country of residence may have certain foreign asset and/or account reporting or exchange control requirements which may affect his or her ability to acquire or hold Shares under the Agreement or cash received (including proceeds arising from the sale of Shares) in a brokerage or bank account outside Participant’s country. Participant may be required to report such accounts, assets

Appendix-2

or transactions to the tax or other authorities in his or her country. Participant may also be required to repatriate sale proceeds or other funds received as a result of his/her participation in the Plan to his or her country through a designated broker or bank and/or within a certain time after receipt. Participant is responsible for ensuring compliance with such regulations and should consult with his or her personal legal advisor for any details.

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 the Agreement or any receipt of the Option or sale of Shares acquired upon exercise of the Option. Participant should consult his or her own personal tax, legal and financial advisors regarding his or her participation in the Plan and the Agreement before taking any action related to the Option or the Shares.

Imposition of Other Requirements: The Company reserves the right to impose other requirements on Participant, on the Option and/or any Shares issuable upon exercise of the Option, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to require Participant to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

1.2 Incorporation of Terms of Plan. The RSUs are subject to the terms and conditions of the Plan, which are incorporated herein by reference. In the event of any inconsistency between the Plan and this Agreement, the terms of the Plan shall control.

ARTICLE II.

GRANT OF RESTRICTED STOCK UNITS

2.1 Grant of RSUs. Pursuant to the Grant Notice and upon the terms and conditions set forth in the Plan, this Agreement and the Country Provisions (if applicable), effective as of the Grant Date set forth in the Grant Notice, the Company hereby grants to Participant an award of RSUs under the Plan in consideration of Participant’s past and/or continued employment with or service to the Company or any Subsidiary and for other good and valuable consideration, subject to adjustments as provided in Article IX of the Plan.

2.2 Unsecured Obligation to RSUs. Unless and until the RSUs have vested in the manner set forth in Article II hereof, Participant will have no right to receive Common Stock or other property under any such RSUs. Prior to actual payment of any vested RSUs, such RSUs will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company.

2.3 Vesting Schedule. Subject to Section 2.5 hereof, the RSUs shall vest and become nonforfeitable with respect to the applicable portion thereof according to the vesting schedule set forth in the Grant Notice (rounding down to the nearest whole Share). Notwithstanding the foregoing and the Grant Notice, but subject to Section 2.5 hereof, in the event of a Change in Control, the RSUs shall be treated pursuant to Section 9.2 and 9.3 of the Plan.

2.4 Consideration to the Company. In consideration of the grant of the award of RSUs pursuant hereto, Participant agrees to render faithful and efficient services to the Company and its Subsidiaries, as applicable.

2.5 Forfeiture, Termination and Cancellation upon Termination of Service. Notwithstanding any contrary provision of this Agreement or the Plan, upon Participant’s Termination of Service for any or no reason, all Restricted Stock Units which have not vested prior to or in connection with such Termination of Service shall thereupon automatically be forfeited, terminated and cancelled as of the applicable termination date without payment of any consideration by the Company, and Participant, or Participant’s beneficiary or personal representative, as the case may be, shall have no further rights hereunder. No portion of the RSUs which has not become vested as of the date on which Participant incurs a Termination of Service shall thereafter become vested, except as may otherwise be provided by the Administrator or as set forth in a written agreement between the Company (or any Subsidiary that is the employer of Participant) and Participant.

2.6 Issuance of Common Stock upon Vesting.

(a) As soon as administratively practicable following the vesting of any Restricted Stock Units pursuant to Section 2.3 hereof, but in no event later than 30 days after such vesting date (for the avoidance of doubt, this deadline is intended to comply with the “short term deferral” exemption from Section 409A of the Code), the Company shall deliver to Participant (or any transferee permitted under Section 3.2 hereof) either, as determined by the Company, in its sole discretion, (i) a number of Shares or (ii) a cash payment in the amount equal to the Fair Market Value, as of the date of vesting, of a number of Shares equal to the number of RSUs subject to this Award that vest on the applicable vesting date. Notwithstanding the foregoing, in the event Shares are not issued pursuant to Section 10.7 of the Plan, the Shares shall be issued pursuant to the preceding sentence as soon as administratively practicable after the Administrator determines that Shares can again be issued in accordance with such Section.

(b) As set forth in Section 10.5 of the Plan, the Company shall have the authority and the right to deduct or withhold, or to require Participant to remit to the Company, an amount sufficient to satisfy all applicable Tax-Related Items required by law to be withheld with respect to any taxable event arising in connection with the Restricted Stock Units. The Company shall not be obligated to deliver any Shares to Participant or Participant’s legal representative unless and until Participant or Participant’s legal representative shall have paid or otherwise satisfied in full the amount of all Tax-Related Items applicable to the taxable income of Participant resulting from the grant or vesting of the Restricted Stock Units or the issuance of Shares.

2.7 Conditions to Delivery of Shares. The Shares deliverable hereunder may be either previously authorized but unissued Shares, treasury Shares or issued Shares which have then been reacquired by the Company. Such Shares shall be fully paid and nonassessable. The Company shall not be required to issue Shares deliverable hereunder prior to fulfillment of the conditions set forth in Section 10.7 of the Plan.

2.8 Rights as Stockholder. The holder of the RSUs shall not be, nor have any of the rights or privileges of, a stockholder of the Company, including, without limitation, voting rights and rights to dividends, in respect of the RSUs and any Shares underlying the RSUs and deliverable hereunder unless and until such Shares shall have been issued by the Company and held of record by such holder (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Article IX of the Plan.

To the extent permitted by Applicable Law, this Agreement shall be deemed amended to the extent necessary to conform to such applicable exemptive rule.

3.14 Not a Contract of Service Relationship. Nothing in this Agreement or in the Plan shall confer upon Participant any right to commence or continue to serve as an Employee or other Service Provider or shall interfere with or restrict in any way the rights of the Company and its Subsidiaries, which rights are hereby expressly reserved, to discharge or terminate the services of Participant at any time for any reason whatsoever, with or without Cause, except to the extent expressly provided otherwise by Applicable Law or in a written agreement between the Company or a Subsidiary (as applicable) and Participant.

A-4

3.15 Entire Agreement. The Plan, the Grant Notice and this Agreement (including the Country Provisions) constitute the entire agreement of the parties and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject matter hereof, provided that the RSUs shall be subject to any accelerated vesting provisions in any written agreement between Participant and the Company (or any Subsidiary who is the employer of Participant) or a Company plan pursuant to which Participant is eligible to participate, in each case, in accordance with the terms therein.

3.16 Section 409A. This Award is not intended to constitute “nonqualified deferred compensation” within the meaning of Section 409A of the Code (together with any Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the date hereof, “Section 409A”). However, notwithstanding any other provision of the Plan, the Grant Notice or this Agreement, if at any time the Administrator determines that this Award (or any portion thereof) may be subject to Section 409A, the Administrator shall have the right in its sole discretion (without any obligation to do so or to indemnify Participant or any other person for failure to do so) to adopt such amendments to the Plan, the Grant Notice or this Agreement, or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, as the Administrator determines are necessary or appropriate for this Award either to be exempt from the application of Section 409A or to comply with the requirements of Section 409A.

3.17 Limitation on Participant’s Rights. Participation in the Plan confers no rights or interests other than as herein provided. This Agreement creates only a contractual obligation on the part of the Company as to amounts payable and shall not be construed as creating a trust. Neither the Plan nor any underlying program, in and of itself, has any assets. Participant shall have only the rights of a general unsecured creditor of the Company and its Subsidiaries with respect to amounts credited and benefits payable, if any, with respect to the RSUs, and rights no greater than the right to receive the Shares as a general unsecured creditor with respect to RSUs, as and when payable hereunder.

3.18 Rules Particular To Specific Countries.

(a) Generally. Participant shall, if required by the Administrator, enter into an election with the Company or a Subsidiary (in a form approved by the Company) under which any liability to the Company’s (or a Subsidiary’s) Tax-Related Items, including, but not limited to, National Insurance Contributions (“NICs”) and the Fringe Benefit Tax, is transferred to and met by Participant.

(b) Tax Indemnity. Participant shall indemnify and keep indemnified the Company and any of its subsidiaries from and against any Tax-Related Items.

3.19 Special Country Provisions for RSUs Granted to Participants. The RSUs shall be subject to the Country Provisions, if any, for Participant’s country of residence, as set forth in the Country Provisions. If Participant relocates to one of the countries included in the Country Provisions during the life of the RSUs, the special provisions for such country shall apply to Participant, to the extent the Company determines that the application of such provisions is necessary or advisable in order to comply with local law or facilitate the administration of the Plan. The Company reserves the right to impose other requirements on the RSUs and the Shares issuable upon settlement of the RSUs, to the extent the Company determines it is necessary or advisable in order to comply with local laws or facilitate the administration of the Plan, and to require Participant to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

APPENDIX

TO

RESTRICTED STOCK UNIT AWARD AGREEMENT

Special Country Provisions for RSUs for Participants

This Appendix includes special terms and conditions applicable to Participants in the countries below. These terms and conditions are in addition to those set forth in the Restricted Stock Unit Agreement (the “Agreement”) and the Plan, and to the extent there are any inconsistencies between these terms and conditions and those set forth in the Agreement, these terms and conditions shall prevail. Any capitalized term used in this Appendix without definition shall have the meaning ascribed to such term in the Plan or the Agreement, as applicable.

In accepting the RSUs, Participant acknowledges, understands and agrees that:

Appendix-1

Securities Law Notice: Unless otherwise noted, neither the Company nor the Shares are registered with any local stock exchange or under the control of any local securities regulator outside the United States. The Agreement (of which this Appendix is a part), the Plan, and any other communications or materials that Participant may receive regarding participation in the Plan do not constitute advertising or an offering of securities outside the United States, and the issuance of securities described in any Plan-related documents is not intended for public offering or circulation in Participant’s jurisdiction.

General Provisions

Data Privacy. Participant acknowledges and agrees to the data privacy provisions set forth in Section 11.8 of the Plan.

Notifications. This Appendix also includes information 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 respective countries as of [_____________], 2021. Such laws are often complex and change frequently. As a result, the Company strongly recommends that Participant not rely on the information herein as the only source of information relating to the consequences of participation in the Plan because the information may be out of date at the time the RSUs vest or Shares acquired under the Plan are sold. In addition, the information is general in nature and may not apply to the particular situation of Participant, 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 his or her country may apply to his or her situation. Finally, Participant understands that if Participant is a citizen or resident of a country other than the one in which he or she is currently residing or working, the information contained herein may not be applicable to Participant.

English Language. By participating in the Plan, Participant acknowledges that Participant is proficient in the English language, or has consulted with an advisor who is sufficiently proficient in English, so as to allow him or her to understand the terms and conditions of the Plan and the Agreement applicable to Participant’s country of residence. If Participant has received the Agreement and the Plan applicably to his or her country of residence or any other document related to the Plan translated into a language other than English and if the meaning of the translated version is different than the English version, the English version will control.

Currency. Participant understands that, any amounts related to the RSUs will be denominated in U.S. dollars and will be converted to any local currency using a prevailing exchange rate in effect at the time such conversion is performed, as determined by the Company. Participant understands and agrees that neither the Company nor any affiliate shall be liable for any foreign exchange rate fluctuation between Participant’s local currency and the U.S. dollar that may affect the value of the RSUs, or of any amounts due to Participant or as a result of the subsequent sale of any Shares acquired under the RSUs.

Foreign Asset/Account Reporting; Exchange Controls. Participant’s country of residence may have certain foreign asset and/or account reporting or exchange control requirements which may affect his or her ability to acquire or hold Shares under the Agreement or cash received (including proceeds arising from the sale of Shares) in a brokerage or bank account outside Participant’s country. Participant may be

Appendix-2

required to report such accounts, assets or transactions to the tax or other authorities in his or her country. Participant may also be required to repatriate sale proceeds or other funds received as a result of his/her participation in the Plan to his or her country through a designated broker or bank and/or within a certain time after receipt. Participant is responsible for ensuring compliance with such regulations and should consult with his or her personal legal advisor for any details.

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 the Agreement or any receipt of the RSUs or sale of Shares acquired upon settlement of the RSUs. Participant should consult his or her own personal tax, legal and financial advisors regarding his or her participation in the Plan and the Agreement before taking any action related to the RSUs or the Shares.

Imposition of Other Requirements. The Company reserves the right to impose other requirements on Participant, on the RSUs and/or any Shares issuable upon settlement of the RSUs, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to require Participant to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.
