RESTRICTED STOCK UNIT AGREEMENT

Restricted Stock Unit Transferability	This grant is an Award of Restricted Stock Units in the number of Restricted Stock Units set forth on the first page of this Agreement (or, in the case of electronic delivery, as set forth in the grant details for this Award set forth in the Company's selected broker's website), subject to the vesting conditions described in this Agreement. Your Restricted Stock Units may not be transferred, assigned, pledged or hypothecated, whether by operation of law or otherwise, nor may the Restricted Stock Units be made subject to execution, attachment or similar process.
Vesting	Your Restricted Stock Units will vest as indicated on the first page of this Agreement (or, in the case of electronic delivery, in accordance with the grant details for this Award set forth the Company's selected broker's website) provided you remain in Service with the Company or any Affiliate on each applicable vesting date and meet any applicable vesting requirements set forth in this Agreement. Except as provided in this Agreement, or in any other agreement between you and the Company, no additional Restricted Stock Units will vest after your Service has terminated.
Share Delivery; Vested Units; Tax-Related Items	Shares of Stock underlying the vested portion of the Restricted Stock Units will be delivered to you by the Company as soon as practicable following the applicable vesting date for those shares of Stock, but in no event beyond 2½ months after the end of the calendar year in which the shares would have been otherwise delivered. On the vesting date (or as soon as practicable thereafter), a brokerage account in your name will be credited with shares of Stock representing the number of shares that vested under this grant (the “Vested Shares”). If the vesting date is not a trading day, the Vested Shares will be delivered on the next trading day (or as soon as practicable thereafter).

Regardless of any action the Companyor the Affiliate to whom you provide Services (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 the Restricted Stock Units and/or your participation in the Plan and legally applicable to you (“Tax-Related Items”), you acknowledge that the ultimate liability for all Tax-Related Items is and remains your responsibility and may exceed the amount actually withheld by the Company or the Employer. You further acknowledge that the Company and/or the Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Restricted Stock Units, including, but not limited to, the grant, vesting or settlement of the Restricted Stock Units, the issuance of shares of Stock upon settlement of the Restricted Stock Units, the subsequent sale of shares of Stock acquired pursuant to such issuance and the receipt of any dividends and/or any dividend equivalents; and (2) do not commit to and are under no obligation to structure the terms of the Award or any aspect of the Restricted Stock Units to reduce or eliminate your liability for Tax-Related Items or achieve any particular tax result. Further, if you have become subject to tax in more than one jurisdiction between the Grant Date and the date of any relevant taxable event, as applicable, you acknowledge that the Companyand/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

By accepting this Award, you agree to establish a brokerage account with the Company's designated broker and irrevocably (i) instruct the Company to deliver the Vested Shares to your account with such broker, or its agents; and (ii) authorize and direct the Company and its broker, or their respective agents, in their discretion, to effect a mandatory sale (“Automatic Sale”), on your behalf, of such portion of the Vested Shares that the Company determines is necessary to satisfy Tax-Related Items (the “Withholding Shares”), with such sale to be effected at the market price per Share at the time of such sale, and (iii) expressly consent to the delivery of the proceeds of the sale of Withholding Shares to the Company, or its agents, to be used as it determines advisable for purposes of funding any applicable Tax-Related Items (whether on behalf of the Company or you as Award holder or Plan participant) with respect to the Restricted Stock Units and your participation in the Plan. You further acknowledge that this irrevocable written instruction is intended to constitute an instruction pursuant to Rule 10b5-1 of the Exchange Act with the Automatic Sale intended to comply with these requirements. As such, all provisions hereof shall be interpreted consistent with Rule 10b5-1 and shall be automatically modified to the extent necessary to comply therewith.

The Company shall be responsible for the payment of any brokerage commissions relating to the sale of the Withholding Shares.

You acknowledge that until the first trading day following the broker's sale of the Withholding Shares, you shall not be entitled to effect transactions in the net Vested Shares, net of any Withholding shares, credited to your brokerage account.

To avoid negative accounting treatment, the Company may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding amounts or other applicable withholding rates. For tax purposes, you are deemed to have been issued the full number of shares of Stock subject to the Vested Shares, notwithstanding that a number of the shares of Stock have been sold, or otherwise withheld, for the purpose of paying the Tax-Related Items due as a result of any aspect of your participation in the Plan.

By accepting this Award you agree to pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of your participation in the Plan that cannot be satisfied by the means of the Automatic Sale. The Company may refuse to issue or deliver the shares of Stock or the proceeds of the sale of shares of Stock, if you fail to comply with your obligations in connection with the Tax-Related Items.

Forfeiture of Unvested Units	Except as specifically provided in this Agreement or as may be provided in other agreements between you and the Company, no additional Restricted Stock Units will vest after your Service with the Company, the Employer or any Affiliate has terminated for any reason and you will forfeit to the Company all of the Restricted Stock Units that have not yet vested or with respect to which all applicable restrictions and conditions have not lapsed.
Death	If your Service terminates because of your death, the Restricted Stock Units granted under this Agreement will automatically vest as to the number of Restricted Stock Units that would have vested had you remained in Service for the 12 month period immediately following your death.
Disability	If your Service terminates because of your Disability, the Restricted Stock Units granted under this Agreement will automatically vest as to the number of Restricted Stock Units that would have vested had you remained in Service for the 12 month period immediately following your Disability.
Termination For Cause	If your Service is terminated for Cause, then you shall immediately forfeit all rights to your Restricted Stock Units and this Award shall immediately terminate.
Leaves of Absence	For purposes of this grant, your Service does not terminate when you go on a bona fide leave of absence approved by the Company, if the terms of your leave provide for continued Service crediting, or when continued Service crediting is required by applicable law. The Company will determine, in its sole discretion, whether and when a leave of absence constitutes a termination of Service under the Plan.
Retention Rights	Neither your Restricted Stock Units nor this Agreement give you the right to be retained by the Company, the Employer or any Affiliate in any capacity and your Service may be terminated at any time and for any reason.
Shareholder Rights	You have no rights as a shareholder unless and until the shares of Stock relating to the Restricted Stock Units have been issued to you (or an appropriate book entry has been made). Except as described in the Plan or herein, no adjustments are made for dividends or other rights if the applicable record date occurs before your shares of Stock are issued (or an appropriate book entry has been made). If the Company pays a dividend on its shares of Stock, you will, however, be entitled to receive a cash payment equal to the per-share dividend paid on the shares of Stock times the number of vested Restricted Stock Units that you hold as of the record date for the dividend.

Nature of Grant In accepting the Award and the Restricted Stock Units, you acknowledge, understand and agree that: (1) the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the Company at any time; (2) the grant of the Restricted Stock Units is voluntary and occasional and does not create any contractual or other right to receive future grants of Restricted Stock Units, or benefits in lieu of Restricted Stock Units, even if Restricted Stock Units have been granted repeatedly in the past; (3) all decisions with respect to future Restricted Stock Unit grants, if any, will be at the sole discretion of the Company; (4) your participation in the Plan is voluntary; (5) the Restricted Stock Units and the shares of Stock subject to the Restricted Stock Units are not intended to replace any pension rights; (6) the Restricted Stock Units and the shares of Stock subject to the Restricted Stock Units 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; (7) the Restricted Stock Unit grant and your participation in the Plan will not be interpreted to form a Service contract or relationship with the Company, the Employer or any Affiliate; (8) the future value of the underlying shares of Stock is unknown and cannot be predicted with certainty; (9) no claim or entitlement to compensation or damages shall arise from forfeiture of the Restricted Stock Units resulting from termination of your Service relationship with the Company or the Employer (for any reason whatsoever and whether or not in breach of contract or local employment laws in the country where you reside, even if otherwise applicable to your employment benefits from the Employer, and/or later found to be invalid), and in consideration of the grant of the Restricted Stock Units to which you are otherwise not entitled, you irrevocably agree never to institute any claim against the Company, the Employer or any Affiliate, waive your ability, if any, to bring any such claim, and release the Company, the Employer or any Affiliate from any such claim; if, notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, then, by accepting this award of Restricted Stock Units, you shall be deemed irrevocably to have agreed not to pursue such claim and agree to execute any and all documents necessary to request dismissal or withdrawal of such claims; (10) in the event of termination of your Service relationship (whether or not in breach of contract or local employment laws in the country where you reside, even if otherwise applicable to your employment benefits from the Employer, and/or later found to be invalid), your right to vest in the Restricted Stock Units under the Plan, if any, will terminate effective as of the date that you are no longer actively providing Services to the Company, the Employer or any Affiliate as a Service Provider and will not be extended by any notice period mandated under local law (e.g., active Service as a Service Provider would not include a period of “garden leave” or similar period); the Committee shall have the exclusive discretion to determine when you are no longer actively providing Services for purposes of your Restricted Stock Units grant; (11) the Restricted Stock Units and the benefits evidenced by this Agreement do not create any entitlement, not otherwise specifically provided for in the Plan or by the Company in its discretion, to have the Restricted Stock Units or any such benefits transferred to, or assumed by, another company, nor to be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the Stock; and (12) the following provisions apply only if you are providing Services outside the United States: (A)the Restricted Stock Units and the shares of Stock subject to the Restricted Stock Units are not part of normal or expected compensation or salary for any purpose and in no event should be considered as compensation for, or relating in any way to, past Services for the Company, the Employer or any Affiliate; (B)you acknowledge and agree that neither the Company, the Employer nor any Affiliate shall be liable for any foreign exchange rate fluctuation between the Employer's local currency and the United States dollar that may affect the value of any proceeds from the sale of shares of Stock acquired under the Plan.

Securities Law Information. You should be aware of the Dutch insider trading rules which may impact the sale of shares of Stock acquired under the Plan. In particular, you may be prohibited from effecting certain transactions if you have inside information regarding the Company.

Under Article 5:56 of the Dutch Financial Supervision Act, anyone who has “inside information” related to an issuing company is prohibited from effectuating a transaction in securities in or from the Netherlands. “Inside information” is defined as knowledge of specific information concerning the Company to which the securities relate that is not public and which, if published, would reasonably be expected to affect the stock price, regardless of the development of the price. The insider could be any employee of the Company or an Affiliate in the Netherlands who has inside information as described above. Given the broad scope of the definition of inside information, certain employees of the Company working at an Affiliate in the Netherlands (including you) may have inside information and, thus, would be prohibited from effectuating a transaction in securities in the Netherlands at a time when you have such inside information.

By accepting the Restricted Stock Units and the underlying shares of Stock, you acknowledge having read and understood the notification above and acknowledge that it is your responsibility to comply with the Dutch insider trading rules, as discussed herein. If you are uncertain whether the insider-trading rules apply to you, you should consult your personal legal advisor.

You understand that the Company has unilaterally, gratuitously and discretionally decided to grant Restricted Stock Units under the Plan to individuals who may be Service Providers of the Company or any Affiliate throughout the world.

Further, you understand that the Restricted Stock Units would not be granted to you but for the assumptions and conditions referred to herein; thus, you acknowledge and freely accept that should any or all of the assumptions be mistaken or should any of the conditions not be met for any reason, then the grant of the Restricted Stock Units and any right to the Restricted Stock Units shall be null and void.

You understand and agree that, as a condition of the grant of the Restricted Stock Units, the termination of your status as a Service Provider for any reason (including the reasons below) will automatically result in the loss of the Restricted Stock Units to the extent the Restricted Stock Units have not vested as of the date you are no longer actively providing Service to the Company or the Employer. In particular, you understand and agree that any unvested Restricted Stock Units as of the date you are no longer actively providing Service will be forfeited without entitlement to the underlying shares of Stock or to any amount of indemnification in the event of a termination of your status as a Service Provider by reason of, but not limited to, resignation, retirement, disciplinary dismissal adjudged to be with cause, disciplinary dismissal adjudged or recognized to be without cause, individual or collective dismissal adjudged or recognized to be without cause, individual or collective dismissal on objective grounds, whether adjudged or recognized to be with or without cause, material modification of the terms of employment under Article 41 of the Workers' Statute, relocation under Article 40 of the Workers' Statute, Article 50 of the Workers' Statute, unilateral withdrawal by the Employer and under Article 10.3 of the Royal Decree 1382/1985.

When receiving foreign payments exceeding €50,000 derived from the ownership of shares of Stock (i.e., dividends or sale proceeds), you must inform the financial institution receiving the payment of the basis upon which such payment is made. You will need to provide the institution with the following information: (i) name, address, and fiscal identification number; (ii) the name and corporate domicile of the Company; (iii) the amount of the payment; the currency used; (iv) the country of origin; (v) the reasons for the payment; and (vi) further information that may be required.
