In the event of any inconsistency between the UK Sub-Plan and this UK Option Agreement, the terms of the UK Option Agreement will control.

ARTICLE II.

PERIOD OF EXERCISABILITY

2.1 Commencement of Exercisability. The Option will vest and become exercisable according to the vesting schedule in the Grant Notice (the “Vesting Schedule”) except that any fraction of a Share as to which the Option would be vested or exercisable will be accumulated and will vest and become exercisable only when a whole Share has accumulated. Notwithstanding anything in the Grant Notice, the UK Sub-Plan or this UK Option Agreement to the contrary, unless the Administrator otherwise determines, the Option will immediately expire and be forfeited as to any portion that is not vested and exercisable as of the Participant’s Termination of Service for any reason.

2.2 Duration of Exercisability. The Vesting Schedule is cumulative. Any portion of the Option which vests and becomes exercisable will remain vested and exercisable until the Option expires. The Option will be forfeited immediately upon its expiration.

(a) The final expiration date in the Grant Notice;

(b) Except as the Administrator may otherwise approve, the expiration of three (3) months from the date of Participant’s Termination of Service, unless Participant’s Termination of Service is for Cause or by reason of Participant’s death or Disability;

(c) Except as the Administrator may otherwise approve, the expiration of one (1) year from the date of Participant’s Termination of Service by reason of Participant’s death or Disability; and

(d) Except as the Administrator may otherwise approve, Participant’s Termination of Service for Cause.

ARTICLE III.

EXERCISE OF OPTION

3.1 Person Eligible to Exercise. During Participant’s lifetime, only Participant may exercise the Option. After Participant’s death, any exercisable portion of the Option may, prior to the time the Option expires, be exercised by Participant’s Designated Beneficiary as provided in the UK Sub-Plan.

3.2 Partial Exercise. Any exercisable portion of the Option or the entire Option, if then wholly exercisable, may be exercised, in whole or in part, according to the procedures in the UK Sub-Plan at any time prior to the time the Option or portion thereof expires, except that the Option may only be exercised for whole Shares.

3.3 UK Tax Obligations.

(a) Tax Indemnity. Participant agrees to indemnify and keep indemnified the Company and his/her employing company (“Employer”), if different, from and against any liability for or obligation to pay any Tax Liability (a “Tax Liability” being any liability for income tax, employee’s National Insurance contributions and (at the discretion of the Company) employer’s National Insurance Contributions (or other similar obligations to pay tax and social security wherever in the world arising)) that is attributable to: (1) the grant or exercise of, or any benefit derived by Participant from, the Option or the Shares which are the subject of the Option; (2) the transfer or issue of Shares to Participant on satisfaction of the Option or any other benefit on exercise of the Option; (3) any restrictions applicable to the Shares held by the Participant ceasing to apply to those shares; or (4) the disposal of any Shares.

(b) Tax Liability. The Option cannot be exercised until Participant has made such arrangements as the Company may require for the satisfaction of any Tax Liability that may arise in connection with the exercise of the Option and/or the acquisition of the Shares by the Participant. The Company shall not be required to issue, allot or transfer Shares until Participant has satisfied this obligation.

(c) Election. Participant undertakes that, upon request by the Company, he/she will (on or within 14 days of acquiring the Shares) join with his/her Employer in electing, pursuant to Section 431(1) of the Income Tax (Earnings and Pensions) Act 2003 (“ITEPA”) that, for relevant tax purposes, the market value of the Shares acquired on exercise of the Option on any occasion will be calculated as if the Shares were not restricted and Sections 425 to 430 (inclusive) of ITEPA are not to apply to such Shares.

(d) The Company has the right and option, but not the obligation, to treat Participant’s failure to provide timely payment in accordance with the UK Sub-Plan of any withholding tax arising in connection with the Option as Participant’s election to satisfy all or any portion of the withholding tax by requesting the Company retain Shares otherwise issuable under the Option.

(e) Participant acknowledges that Participant is ultimately liable and responsible for all taxes owed in connection with the Option, regardless of any action the Company or any Subsidiary takes with respect to any tax withholding obligations that arise in connection with the Option. Neither the Company nor any Subsidiary makes any representation or undertaking regarding the treatment of any tax withholding in connection with the awarding, vesting or exercise of the Option or the subsequent sale of Shares. The Company and the Subsidiaries do not commit and are under no obligation to structure the Option to reduce or eliminate Participant’s Tax Liability.

4.5 Successors and Assigns. The Company may assign any of its rights under this UK Option Agreement to single or multiple assignees, and this UK Option Agreement will inure to the benefit of the successors and assigns of the Company.

4.9 Limitation on Participant’s Rights. Participation in the UK Sub-Plan confers no rights or interests other than as herein provided. This UK Option Agreement creates only a contractual obligation on the part of the Company as to amounts payable and may not be construed as creating a trust. Neither the UK Sub-Plan nor any underlying program, in and of itself, has any assets. Participant will have only the rights of a general unsecured creditor of the Company 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.

4.10 Not a Contract of Employment. Nothing in the UK Sub-Plan, the Grant Notice or this UK Option Agreement confers upon Participant any right to continue in the employ of the Company or any Subsidiary or interferes with or restricts 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 in a written agreement between the Company or a Subsidiary and Participant.

4.11 Counterparts. The Grant Notice may be executed in one or more counterparts, including by way of any electronic signature, subject to Applicable Law, each of which will be deemed an original and all of which together will constitute one instrument.

4.12 Incentive Stock Options. If the Option is designated as an Incentive Stock Option:

(a) Participant acknowledges that to the extent the aggregate fair market value of shares (determined as of the time the option with respect to the shares is granted) with respect to which options intended to qualify as “incentive stock options” under Section 422 of the Code, including the Option, are exercisable for the first time by Participant during any calendar year exceeds $100,000 or if for any other reason such options do not qualify or cease to qualify for treatment as “incentive stock options” under Section 422 of the Code, such options (including the Option) will be treated as non-qualified options. Participant further acknowledges that the rule set forth in the preceding sentence will be applied by taking the Option and other options into account in the order in which they were granted, as determined under Section 422(d) of the Code. Participant acknowledges that amendments or modifications made to the Option pursuant to the UK Sub-Plan that would cause the Option to become a Non-Qualified Stock Option will not materially or adversely affect Participant’s rights under the Option, and that any such amendment or modification shall not require Participant’s consent. Participant also acknowledges that if the Option is exercised more than three (3) months after Participant’s Termination of Service as an Employee, other than by reason of death or disability, the Option will be taxed as a Non-Qualified Stock Option.

(b) Participant will give prompt written notice to the Company of any disposition or other transfer of any Shares acquired under this UK Option Agreement if such disposition or other transfer is made (a) within two (2) years from the Grant Date or (b) within one (1) year after the transfer of such Shares to Participant. Such notice will specify the date of such disposition or other transfer and the amount realized, in cash, other property, assumption of indebtedness or other consideration, by Participant in such disposition or other transfer.

4.13 Data Protection. The Company and all its Subsidiaries may transfer, collect, use, process or disclose, in electronic or other form, such information to third parties, including where they are situated outside the European Economic Area in countries where the level of data protection may not be as high as in the Participant’s country of residence, in the event that such disclosure is in their view required for the performance of their obligations under the Plan. The Company and all Group Companies shall ensure that such collection, use, processing and transfers are made in accordance with the EU General Data Protection Regulation and other applicable data protection laws in any other jurisdiction.

4.14 Acknowledgement. Participant acknowledges that neither this UK Option Agreement nor the UK Sub-Plan has been issued, nor has it been approved by, an authorised person within the meaning of the Financial Services and Markets Act 2000 of the United Kingdom and is being directed at the Participant because the offer to which this UK Option Agreement and the UK Sub-Plan relate has been determined as having regard to the Participant’s circumstances as an employee of the Company. This UK Option Agreement is strictly confidential and is not for distribution to, and may not be acted upon by, any other person other than the person to whom it has been specifically addressed.
