6.7 Governing Law. The laws of the State of Delaware shall govern the interpretation, validity, administration, enforcement and performance of the terms of this Agreement regardless of the law that might be applied under principles of conflicts of laws.

6.8 Conformity to Securities Laws. The Optionee acknowledges that the Plan and this Agreement are intended to conform to the extent necessary with all provisions of the Securities Act and the Exchange Act and any and all regulations and rules promulgated by the Securities and Exchange Commission thereunder, and state securities laws and regulations. Notwithstanding anything herein to the contrary, the Plan shall be administered, and the Option is granted and may be exercised, only in such a manner as to conform to such laws, rules and regulations. To the extent permitted by applicable law, the Plan and this Agreement shall be deemed amended to the extent necessary to conform to such laws, rules and regulations.

6.9 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 shall be made that would materially impair the rights of an Optionee under the Option without such Optionee’s consent.

6.14 Section 409A. The intent of the parties is that payments and benefits under this Agreement comply with, or be exempt from the requirements of, Section 409A of the Code to the extent subject thereto, and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted and be administered to be in compliance therewith or exempt therefrom. Any payments described in this Agreement that are due within the “short-term deferral period” as defined in Section 409A of the Code shall not be treated as deferred compensation unless applicable law requires otherwise.

Notwithstanding any provisions in this Agreement, the Option shall be subject to any special provisions set forth in the Country Addendum attached hereto as Exhibit A for the Optionee’s country of residence, if any. If the Optionee relocates to one of the countries included in the Country Addendum or the United States during the term of the Option, the special provisions for such country shall apply to Optionee 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.

6.16 Waiver. The Optionee 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 Optionee.

6.17 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.

6.18 Tax Withholding. Regardless of any action the Company and its Affiliates or, if Optionee 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 Optionee’s participation in the Plan and legally applicable to Optionee (“Tax-Related Items”), Optionee acknowledges that the ultimate liability for all Tax-Related Items is and remains Optionee’s responsibility and may exceed the amount actually withheld by the Company or any Affiliate. Optionee 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 Option, including, but not limited to, the grant, vesting or exercise of the Option, the subsequent sale of Shares acquired pursuant to such exercise 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 Option to reduce or eliminate Optionee’s liability for Tax-Related Items or achieve any particular tax result. Further, if Optionee 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, Optionee 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 Optionee 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, Optionee 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, Optionee is deemed to have been issued the full number of Shares subject to the exercised Options, notwithstanding that a number of the Shares are held back solely for the purpose of paying the Tax-Related Items due as a result of any aspect of Optionee’s participation in the Plan.

6.19 Data Privacy. Optionee hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of Optionee’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 Optionee’s participation in the Plan. Optionee

9

understands that the Company and the Employer may hold certain personal information about Optionee, including, but not limited to, Optionee’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 Options or any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in Optionee’s favor (“Data”), for the exclusive purpose of implementing, administering and managing the Plan. Optionee 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. Optionee 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 Optionee’s country. Optionee 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. Optionee 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 Optionee’s participation in the Plan. Optionee understands that Data will be held only as long as is necessary to implement, administer and manage Optionee’s participation in the Plan. Optionee 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, Optionee understands that he or she is providing the consents herein on a purely voluntary basis. If Optionee does not consent, or if Optionee 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 Optionee’s consent is that the Company would not be able to grant Optionee Options or other equity awards or administer or maintain such awards. Therefore, Optionee understands that refusing or withdrawing his or her consent may affect Optionee’s ability to participate in the Plan. For more information on the consequences of Optionee’s refusal to consent or withdrawal of consent, Optionee understands that he or she may contact the Company.
