GRANT OF RESTRICTED STOCK UNITS

2.1 Grant of RSUs. In consideration of the Participant’s employment or service to the Company or any Affiliate and other good and valuable consideration, effective as of the Grant Date set forth in the Notice, the Company hereby grants to the Participant an Award of RSUs under the Plan, upon the terms and conditions set forth in the Plan and this Agreement.

2.2 Unsecured Obligation. Unless and until the RSUs have vested in the manner set forth in Article 2 hereof, the Participant will have no right to receive Common Stock with respect to any such RSUs.

(a) Upon the Participant’s termination of employment or service with the Company and all Affiliates thereof, the RSUs shall be treated as follows [for employee awards only:, except as specifically provided in an employment agreement between the Company and the Participant]:

(i) In the event that the employment or service of a Participant with the Company and all Affiliates thereof (including by reason of the Participant’s employer ceasing to be an Affiliate of the Company) shall terminate for any reason other than Cause, unvested RSUs granted to such Participant shall terminate at the close of business on the date of such termination.

Notwithstanding the above, earned Shares shall be treated as delivered on the first business day following the Vesting Date (the “Delivery Date”) provided that they are delivered on a date following the Delivery Date that is in the same calendar year as the Delivery Date. On the Delivery Date, the Company shall deliver to the Participant (or any transferee permitted under Section 4.2 hereof) a number of Shares (either by delivering one or more certificates for such Shares or by entering such Shares in book entry form, as determined by the Company in its sole discretion) equal to the number of RSUs subject to this Agreement that vest on the Vesting Date, unless such RSUs terminate prior to the Vesting Date pursuant to Section 2.5 hereof.

Participant to remit to the Company, an amount sufficient to satisfy all applicable federal, state and local taxes 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 new certificate representing Shares to the Participant or the Participant’s legal representative or enter such Shares in book entry form unless and until the Participant or the Participant’s legal representative shall have paid or otherwise satisfied in full the amount of all federal, state and local taxes applicable to the taxable income of the Participant resulting from the grant or vesting of the Restricted Stock Units or the issuance of Shares.]

4.10 Amendments and Termination. To the extent permitted by the Plan, this Agreement may be wholly or partially amended, altered or terminated at any time or from time to time by the Administrator or the Board, but no amendment, alteration or termination of this Agreement shall be made that would materially impair the rights of a Participant under the RSUs without such Participant’s consent.

4.14 Section 409A. This Restricted Stock Unit Award is intended to comply with Code Section 409A to the extent subject thereto and shall be interpreted in accordance with Code Section 409A and 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 Grant Date. Notwithstanding any provision in the Plan or Agreement to the contrary, no payment or distribution under this Agreement that constitutes an item of deferred compensation under Code Section 409A and becomes payable by reason of the Participant’s termination of employment or service with the Company will be made to the Participant until the Participant’s termination of employment or service constitutes a “separation from service” (as defined in Code Section 409A). For purposes of this Agreement, each amount to be paid or benefit to be provided shall be construed as a separate identified payment for purposes of Code Section 409A. [For employee awards only: If a participant is a “specified employee” (as defined in Code Section 409A), then to the extent necessary to avoid the imposition of taxes under Code Section 409A, such Participant shall not be entitled to any payments upon a termination of his or her employment or service until the earlier of: (i) the expiration of the six (6)-month period measured from the date of such Participant’s “separation from service” or (ii) the date of such Participant’s death. Upon the expiration of the applicable waiting period set forth in the preceding sentence, all payments and benefits deferred pursuant to this Section 4.15 (whether they would have otherwise been payable in a single lump sum or in installments in the absence of such deferral) shall be paid to such Participant in a lump sum as soon as practicable, but in no event later than sixty (60) calendar days, following such expired period, and any remaining payments due under this Agreement will be paid in accordance with the normal payment dates specified for them herein.] The Administrator may, in its discretion, adopt such amendments to the Plan, this Agreement or the Notice 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 to comply with the requirements of Code Section 409A.

A-5

4.15 Electronic Signature; Electronic Delivery and Acceptance. The Participant’s electronic signature of this Agreement shall have the same validity and effect as a signature affixed by hand. The Company may, in its sole discretion, decide to deliver any documents related to the Participant’s current or future participation in the Plan by electronic means. The Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company.

4.16 Addendum. Notwithstanding any provisions in this Agreement, the RSUs shall be subject to any special provisions set forth in the Country Addendum attached hereto as Exhibit A for the Participant’s country of residence, if any. If the Participant relocates to one of the countries included in the Country Addendum or the United States during the term 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 for legal or administrative reasons. The Country Addendum constitutes part of this Agreement.

4.17 Waiver. The Participant acknowledges that a waiver by the Company of a breach of any provision of this Agreement shall not operate or be construed as a waiver of any other provision of this Agreement, or of any subsequent breach by the Participant.

4.18 Severability. The provisions of this Agreement are severable and if any one or more provisions are determined to be illegal or otherwise unenforceable, in whole or in part, the remaining provisions shall nevertheless be binding and enforceable.

4.19 Tax Withholding. Regardless of any action the Company and its Affiliates or, if Participant is an employee, the employer (the “Employer”) takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax related items related to Participant’s participation in the Plan and legally applicable to Participant (“Tax-Related Items”), Participant acknowledges that the ultimate liability for all Tax-Related Items is and remains Participant’s responsibility and may exceed the amount actually withheld by the Company or any Affiliate. Participant further acknowledges that the Company, its Affiliates and/or the Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the RSUs, including, but not limited to, the grant or vesting of the RSUs, the subsequent sale of Shares acquired pursuant to the RSUs and the receipt of any dividends; and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the RSUs to reduce or eliminate Participant’s liability for Tax-Related Items or achieve any particular tax result. Further, if Participant has become subject to tax in more than one jurisdiction between the Grant Date and the date of any relevant taxable or tax withholding event, as applicable, Participant acknowledges that the Company, its Affiliates and/or the Employer (or former Employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction. If Participant is subject to Tax-Related Items 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 and/or the Employer (or former Employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, Participant is deemed to have been issued the full number of Shares subject to the RSUs, notwithstanding that a number of the Shares are

A-6

held back solely for the purpose of paying the Tax-Related Items due as a result of any aspect of Participant’s participation in the Plan.

4.20 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 Agreement and any other grant materials by and among, as applicable, the Company, the Employer and any Affiliate of the Company for the exclusive purpose of implementing, administering and managing Participant’s participation in the Plan. Participant understands that the Company and the Employer 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 RSUs 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 may be transferred to a stock plan transfer agent, trustee, broker or administrator designated by the Company or any such other stock plan service provider as may be designated 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 recipient’s country (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, the Company’s designated transfer agent, trustee, stock plan broker or administrator 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 purposes of implementing, administering and managing Participant’s 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 that 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 the Company. 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 employment or service relationship with the Company, its Affiliates or Employer 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 RSUs 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 the Company.
