(b)Stock Plan Administration Vendors. The Company may transfer Data to a designated third-party external broker or such other independent stock plan vendors, as may be selected by the Company in the future, which shall assist the Company with the implementation, administration and management of the Plan. Such vendor(s) may open an account for the Grantee to receive and trade shares of Common Stock underlying this Award.

(c)Data Retention.

If applicable and upon request of the Company, the Grantee agrees to provide an executed acknowledgement or any data privacy consent to the Company (or any other acknowledgements, agreements or consents as may be required by the Company) that the Company may deem necessary to obtain under the data privacy laws in the Grantee’s jurisdiction, either now or in the future. The Grantee understands that the Grantee will not be able to participate in the Plan if the Grantee fails to execute any such acknowledgement, agreement or consent requested by the Company.

The Administrator may at any time accelerate the vesting schedule specified in this Paragraph 2.

3. Termination of Relationship with the Company. If the Grantee ceases to be an Eligible Participant for any reason other than death prior to the Vesting Date(s) set forth in Paragraph 2 above, any Performance Stock Units that have not vested as of such Vesting Date(s) shall automatically and without notice terminate and be forfeited, and neither the Grantee nor any of his or her successors, heirs, assigns, or personal representatives will thereafter have any further rights or interests in such unvested Performance Stock Units.

Performance Stock Unit Award Agreement
Granted Under 2018 Stock Incentive Plan

- 12 -

Name of Grantee: [ ]

No. of Performance Stock Units: [ ]

Grant Date: [ ]

1.Restrictions on Transfer of Award. This Award may not be sold, transferred, pledged, assigned or otherwise encumbered or disposed of by the Grantee, and any shares of Stock issuable with respect to the Award may not be sold, transferred, pledged, assigned or otherwise encumbered or disposed of until (i) the Performance Stock Units have vested as provided in Paragraph 2 of this Agreement and (ii) shares of Stock have been issued to the Grantee in accordance with the terms of the Plan and this Agreement.

2.Vesting of Performance Stock Units. The restrictions and conditions of Paragraph 1 of this Agreement shall lapse on the date or dates (each, a “Vesting Date”) specified in the following schedule so long as the Grantee remains an employee or officer of, or consultant or advisor to, the Company or a subsidiary (an “Eligible Participant”) on such Vesting Date(s). If a series of Vesting Dates is specified, then the restrictions and conditions in Paragraph 1 shall lapse only with respect to the number of Performance Stock Units specified as vested on such date.

[VESTING EVENT];

provided that any determination as to whether or not a vesting event for such Performance Stock Units has been met shall be made in the sole discretion of the People, Culture and Compensation (the “Committee”) of the Company’s Board of Directors and such date of vesting shall be the date so determined by the Committee.

Notwithstanding the foregoing, this award will become fully vested in the event the Grantee dies while he or she is an Eligible Participant prior to the Vesting Date(s) (and, in such case, the date of death shall be deemed a Vesting Date for purposes of Section 4 of this Agreement).

The Administrator may at any time accelerate the vesting schedule specified in this Paragraph 2.

3.Termination of Relationship with the Company. If the Grantee ceases to be an Eligible Participant for any reason other than death prior to the Vesting Date(s) set forth in Paragraph 2 above, any Performance Stock Units that have not vested as of such Vesting Date(s) shall automatically and without notice terminate and be forfeited, and neither the Grantee nor any of his or her successors, heirs, assigns, or personal representatives will thereafter have any further rights or interests in such unvested Performance Stock Units.

4.Issuance of Shares of Stock. As soon as practicable following each Vesting Date (but in no event later than two and one-half months after the end of the year in which the Vesting Date

- 13 -

occurs), the Company shall issue to the Grantee the number of shares of Stock equal to the aggregate number of Performance Stock Units that have vested pursuant to Paragraph 2 of this Agreement on such date and the Grantee shall thereafter have all the rights of a stockholder of the Company with respect to such shares. Notwithstanding the foregoing, if the Grantee is resident or employed outside of the United States, the Company may, in its sole discretion, settle the Performance Stock Units in the form of a cash payment to the extent settlement in shares of Stock: (i) is prohibited under local law; (ii) would require the Grantee, the Company or its subsidiaries to obtain the approval of any governmental and/or regulatory body in the Grantee’s country of residence (or country of employment, if different); (iii) would result in adverse tax consequences for the Grantee, the Company or the Employer; or (iv) is administratively burdensome. Alternatively, the Company may, in its sole discretion settle the Performance Stock Units in the form of shares of Stock, but require the Grantee to sell such shares immediately or within a specified period following the Grantee’s termination of employment (in which case, this Agreement shall give the Company the authority to issue sales instructions on the Grantee’s behalf).

5.Incorporation of Plan. Notwithstanding anything herein to the contrary, this Agreement shall be subject to and governed by all the terms and conditions of the Plan. Capitalized terms in this Agreement shall have the meaning specified in the Plan, unless a different meaning is specified herein.

6.Responsibility for Taxes. The Grantee acknowledges that, regardless of any action taken by the Company or the Employer with respect to any or all income tax (including U.S. federal, state and local taxes and/or non-U.S. taxes), social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to the Grantee’s participation in the Plan and legally applicable to the Grantee (“Tax-Related Items”), the ultimate liability for all Tax-Related Items is and remains the Grantee’s personal responsibility and may exceed the amount, if any, actually withheld by the Company or the Employer. The Grantee further acknowledges that the Company and/or the Employer (a) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of this Award, including, but not limited to, the grant of this Award, the vesting of this Award, the issuance or sale of shares of Stock, or the receipt of any dividends; and (b) do not commit to and are under no obligation to structure the terms of this Award or any aspect of the Plan to reduce or eliminate the Grantee’s liability for Tax-Related Items or achieve any particular tax result. Further, if the Grantee is subject to Tax-Related Items in more than one jurisdiction, the Grantee 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.

Prior to any relevant taxable or tax withholding event, as applicable, the Grantee agrees to make arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, the Grantee authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy their withholding obligations with regard to any Tax-Related Items by one or a combination of the following: (a) withholding from the Grantee’s wages or other cash compensation payable to the Grantee by the Company and/or the Employer, (b) withholding from proceeds of the sale of shares of Stock issued under the Plan, either through a voluntary sale or through a mandatory sale arranged by the Company (on the Grantee’s behalf pursuant to this authorization without further consent) to cover the Tax-Related Items required to be withheld, and (c) withholding in shares of Stock to be issued upon vesting under the Plan; provided, if the Grantee is a Section 16 officer of the Company under the U.S. Securities and Exchange Act of 1934, as amended (the “Exchange Act”), the withholding obligations for any Tax-Related Items shall be satisfied by withholding in shares of Stock to be issued upon vesting under the Plan.

- 14 -

The Company may withhold or account for Tax-Related Items by considering the minimum applicable rate. If the obligation for Tax-Related Items is satisfied by withholding in shares of Stock, for tax purposes, the Grantee will be deemed to have been issued the gross number of shares of Stock, notwithstanding that a number of the shares of Stock are held back solely for the purpose of paying the Tax-Related Items.

Finally, the Grantee agrees 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 the Grantee’s acceptance of this Award that cannot be satisfied by the means previously described. The Company may refuse to issue or deliver the shares of Stock or the proceeds of the sale of shares of Stock if the Grantee fails to comply with the Grantee’s obligations in connection with the Tax-Related Items.

7.Section 409A of the Code. This Agreement shall be interpreted in such a manner that all provisions relating to the settlement of this Award are exempt from the requirements of Section 409A of the Code as “short-term deferrals” as described in Section 409A of the Code.

8.No Obligation to Continue Service Relationship. Neither the Company nor any subsidiary is obligated by or as a result of the Plan or this Agreement to continue the Grantee in employment or other service relationship and neither the Plan nor this Agreement shall interfere in any way with the right of the Company or any subsidiary to terminate the employment or other service relationship of the Grantee at any time.

9.Nature of Grant. By accepting the grant of this Award, the Grantee acknowledges, understands and agrees that:

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

b.the grant of this Award is voluntary and does not create any contractual or other right to receive future Performance Stock Units or benefits in lieu of Performance Stock Units, even if Performance Stock Units have been granted in the past;

c.all decisions with respect to future Performance Stock Units or other grants, if any, will be at the sole discretion of the Company;

d.the grant of this Award and the Grantee’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, the Employer or any other subsidiary, and shall not interfere with the ability of the Company, the Employer or any other subsidiary to terminate the employment relationship (if any);

e.the Grantee is voluntarily participating in the Plan;

f.this Award and any shares of Stock acquired under the Plan, and the income from and value of same, are not intended to replace any pension rights or compensation;

g.this Award and any shares of Stock acquired under the Plan, and the income from and value of same, are extraordinary items that do not constitute compensation of any

- 15 -

kind for services of any kind rendered to the Company or the Employer, and which are outside the scope of the Grantee’s employment and the Grantee’s employment contract, if any;

h.this Award and any shares of Stock acquired under the Plan, and the income from and value of same, are not part of normal or expected compensation or salary for any purpose, including, without limitation, calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, holiday pay, bonuses, long-service awards, leave-related payments, holiday top-up, pension or retirement or welfare benefits or similar mandatory payments;

i.the future value of the underlying shares of Stock is unknown, indeterminable and cannot be predicted with certainty and the value of such shares of Stock issued under the Plan may increase or decrease in the future;

j.no claim or entitlement to compensation or damages shall arise from forfeiture of this Award resulting from termination of the Grantee’s status as an Eligible Participant (regardless of the reason for the termination and whether or not the termination is later found to be invalid or in breach of employment laws in the jurisdiction where the Grantee is employed or the terms of the Grantee’s employment agreement, if any);

k.on the date of termination of the Grantee’s status as an Eligible Participant (regardless of the reason for the termination and whether or not the termination is later found to be invalid or in breach of employment laws in the jurisdiction where the Grantee is employed or the terms of the Grantee’s employment agreement, if any), the Grantee’s right to continue vesting in this Award, if any, will terminate (for purposes of the foregoing, the Committee shall have exclusive discretion to determine the effective date the Grantee is no longer an Eligible Participant); and

l.neither the Company, the Employer, nor any other subsidiary shall be liable for any foreign exchange rate fluctuation between the Grantee’s local currency and the United States Dollar that may affect the value of the shares of Stock or any amounts due pursuant to the issuance of shares of Stock, or the subsequent sale of any shares of Stock acquired under the Plan.

10.No Advice Regarding Grant. The Grantee acknowledges that neither the Company nor the Employer are providing any tax, legal or financial advice, nor is the Company or the Employer making any recommendations regarding the Grantee’s acceptance of this Award, participation in the Plan or sale of shares of Stock. The Grantee should consult the Grantee’s own personal tax, legal and financial advisors regarding the Grantee’s participation in the Plan before taking any action related to the Plan.

11.Integration. This Agreement constitutes the entire agreement between the parties with respect to this Award and supersedes all prior agreements and discussions between the parties concerning such subject matter.

12.Data Privacy.

a.Data Collection and Usage. The Company collects, processes and transfers personal data about the Grantee, in electronic or other form, including but not limited to, the Grantee’s name, home address, email address and telephone number, date of birth, social insurance or social security number, passport number or other national identification number, salary, nationality, job title, any shares of Common Stock or directorships held in the Company, details of all Performance Stock Units or any

- 16 -

other entitlement to shares of Common Stock or equivalent benefits awarded, canceled, exercised, vested, unvested or outstanding in the Grantee’s favor, which the Company and the Company Affiliates receive from the Grantee or the Employer (“Data”) for the purposes of implementing, administering and managing the Plan. The legal basis, where required, for the processing of Data is the Grantee’s consent, compliance with relevant laws or regulations to which the Company is subject to or the pursuit by the Company of its respective legitimate interests not outweighed by the Grantee’s interests, rights or freedoms as needed to provide the requested services to the Grantee in accordance with the Plan.

b.Stock Plan Administration Vendors. The Company may transfer Data to a designated third-party external broker or such other independent stock plan vendors, as may be selected by the Company in the future, which shall assist the Company with the implementation, administration and management of the Plan. Such vendor(s) may open an account for the Grantee to receive and trade shares of Common Stock. The Grantee may be asked to acknowledge, or agree to, separate terms and data processing practices with the vendor(s) with such agreement being a condition of participation in the Plan.

c.International Data Transfers. Data will be transferred from the Grantee’s country to the United States or elsewhere, where the Company, the Company Affiliates and its vendors are based. The Grantee’s country or jurisdiction may have different data privacy and data protection laws and regulations than the recipient’s country (e.g. the United States or otherwise) and thus the level of data protection provided may not be equivalent to the one offered in the Grantee’s country of residence. The Company’s legal basis, where required, for the transfer of Data is the pursuit by the Company of its respective legitimate interests not outweighed by the Grantee’s interests, rights or freedoms as needed to provide the requested services to the Grantee in accordance with the Plan. Where Data are to be transferred to a Third Country, as defined by applicable data protection laws, the Company and the Company Affiliates shall ensure that the level of data protection is equivalent to the one afforded in the Grantee’s country of residence, especially if such country is subject to applicable data privacy and data protection laws and regulations; such an adequate level shall be in particular guaranteed by the Company and the Company Affiliates, by implementing adequate safeguards between the Company and the Company Affiliates and such third parties recipients; in particular by executing appropriate standard contractual clauses as adopted and approved by the applicable governmental or supervisory authority for that purpose and by implementing appropriate technical and organizational security measures to ensure the security of the processing.

An updated list with the details of all recipients of the Grantee’s Data can be made available upon a relevant request to ▇▇▇▇▇▇▇▇@▇▇▇▇▇▇▇.▇▇▇.

d.Data Retention. The Company will hold and use the Data only as long as is necessary to implement, administer and manage the Grantee’s participation in the Plan, or as required to comply with legal or regulatory obligations, including under tax and security laws. In the latter case, the Grantee understands and acknowledges that the Company’s legal basis for the processing of the Data would be compliance with the relevant laws or regulations and the pursuit by the Company of respective legitimate interests not outweighed by the Grantee’s interests, rights or freedoms. When the Company no longer needs the Data for any of the above purposes, the Grantee understands the Company will isolate it from active systems, remove it from its systems, or anonymize it to be used for statistical purposes as the case may be.

- 17 -

e.Data Subject Rights. The Grantee understands that the Grantee may have a number of rights under data privacy and data protection laws and regulations in the Grantee’s jurisdiction. Depending on where the Grantee is based and the applicable data privacy and data protection laws and regulations, such rights may include the right to (i) request access or copies of Data the Company processes, (ii) rectify or supplement Data that is incorrect, incomplete or out-of-date in light of the purposes underlying the processing, (iii) anonymize or delete Data, (iv) restrict or object to the processing of Data, (v) portability of Data, (vi) lodge complaints with competent authorities in the Grantee’s jurisdiction, (vii) receive a list with the names and addresses of any potential recipients of the Grantee’s Data and/or (viii) receive information about the possibility of not giving consent to process Data and the consequences of not giving consent.

f.Voluntariness and Consequences of Consent Denial or Withdrawal. Participation in the Plan is voluntary and the Grantee is providing the consents herein on a free and purely voluntary basis. If the Grantee does not consent, or if the Grantee later seeks to revoke the Grantee’s consent, the Grantee’s salary from or employment and career with the Company or the Employer will not be affected; the only adverse consequence of refusing or withdrawing the Grantee’s consent is that the Grantee’s ability to participate to the Plan may be affected, as the Company would not (or no longer) be able to grant this Award or other equity awards to the Grantee or administer or maintain such awards. Please note that withdrawal of consent does not affect any processing of Data carried out prior to and up to the date of such withdrawal.

Finally, the Grantee understands that the Company as the Data Controller of the Data may rely on a different legal basis for the processing or transfer of Data in the future and/or request that the Grantee provide supplementary consents or provide the Grantee with additional privacy related information as the case may be. If applicable and upon request of the Company, the Grantee agrees to provide an executed acknowledgement or any data privacy consent to the Employer or the Company (or any other acknowledgements, agreements or consents as may be required by the Employer or the Company) that the Company and/or the Employer may deem necessary to obtain under the data privacy laws in the Grantee’s country, either now or in the future. The Grantee understands that the Grantee will not be able to participate in the Plan if the Grantee fails to execute any such acknowledgement, agreement or consent requested by the Company and/or the Employer.

The Grantee may be subject to certain foreign asset and/or account reporting requirements and/or exchange controls which may affect the Grantee’s ability to hold shares of Stock or cash received from participating in the Plan (including from any dividends or sale proceeds arising from the sale of shares of Stock). The Grantee may be required to report foreign brokerage or bank accounts, assets or transactions to the tax or other authorities in the Grantee’s country of employment (and country of residence, if different).

- 19 -

whether the Grantee should participate in the Plan and acquire shares of Stock under the Plan, or provide the Grantee with any legal, tax or financial advice with respect to the Grantee’s participation in the Plan. The acquisition of shares of Stock involves certain risks, and the Grantee should carefully consider all risk factors and tax considerations relevant to the acquisition of shares of Stock under the Plan and the disposition of them. Further, the Grantee should carefully review all materials related to the Plan, and should consult with the Grantee’s personal legal, tax and financial advisors for professional advice in relation to the Grantee’s personal circumstances.

21.▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Restrictions / Market Abuse Laws. By accepting the grant of Performance Stock Units, the Grantee acknowledges that he or she is bound by all the terms and conditions of the Company’s ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ policy as may be in effect from time to time. The Grantee further acknowledges that, depending on the Grantee’s or his or her broker’s country of residence or where the shares of Stock are listed, he or she may be subject to ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ restrictions and/or market abuse laws which may affect the Grantee’s ability to accept, acquire, sell or otherwise dispose of shares of Stock, rights to shares of Stock (e.g., Performance Stock Units) or rights linked to the value of shares of Stock under the Plan during such times as the Grantee is considered to have “inside information” regarding the Company (as defined by the laws in the applicable jurisdictions). Local ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ laws and regulations may prohibit the cancellation or amendment of orders the Grantee placed before the Grantee possessed inside information. Furthermore, the Grantee could be prohibited from (i) disclosing the inside information to any third party, which may include fellow employees and (ii) “tipping” third parties or causing them otherwise to buy or sell securities. Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under the Company’s ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ policy as may be in effect from time to time. The Grantee acknowledges that it is the Grantee’s responsibility to comply with any applicable restrictions, and the Grantee should speak to his or her personal advisor on this matter.

Nature of Grant. The following provision supplements Paragraph 9 of the Agreement:

By accepting the grant of Performance Stock Units, the Grantee consents to participation in the Plan and acknowledges that he or she has received a copy of the Plan.

The Grantee understands that the Company has unilaterally, gratuitously, and discretionarily decided to offer the Plan to individuals who may be employees of the Company or of its subsidiaries throughout the world. The decision is a temporary decision that is entered into upon the express assumption and condition that any grant of Performance Stock Units will not economically or otherwise bind the Company or any of its subsidiaries presently or in the future, other than as expressly set forth in the Agreement, including this Addendum. Consequently, the Grantee understands that the Plan is offered on the assumption and condition that the Plan and any shares of Stock issued upon vesting is not part of any employment or service contract (either with the Company or any of its subsidiaries) and shall not be considered a mandatory benefit, salary for any purpose (including severance compensation), or any other right whatsoever.

Further, the Grantee understands and agrees that the Company does not guarantee that any benefit whatsoever shall arise from the Performance Stock Units, which is gratuitous and discretionary, since the future value of the shares of Stock is unknown and unpredictable. Finally, the Grantee understands that the Company would not be making this grant of Performance Stock Units but for the assumptions and conditions referred to above; thus, the

- 26 -

Grantee expressly acknowledges and freely accepts 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 Performance Stock Units shall be null and void and the Plan shall not have any effect whatsoever.

The Grantee understands and agrees that, as a condition of his or her participation in the Plan, the termination of the Grantee’s employment for any reason will automatically result in the cancellation of any Performance Stock Units granted to the Grantee under the Plan. In particular, the Grantee understands and agrees that, unless otherwise expressly provided for by the Company, the Grantee will not be permitted to continue to vest in the Performance Stock Units if the Grantee terminates employment for any reason of, including, 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 layoff on objective grounds, whether adjudged to be with cause or adjudged or recognized to be 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 Grantee’s employer, and under Article 10.3 of Royal Decree 1382/1985. The Company, in its sole discretion, shall determine the date when the Grantee’s status as an employee has terminated for purposes of the right of Performance Stock Units granted under the Plan to vest.

Responsibility for Taxes. The following provision supplements Paragraph 6 of the Agreement:

Without limitation to Paragraph 6 of the Agreement, the Grantee hereby agrees that he or she is liable for all Tax-Related Items and hereby covenants to pay all such Tax-Related Items, as and when requested by the Company or (if different) the Grantee’s employer or by Her Majesty’s Revenue & Customs (“HRMC”) (or any other tax authority or any other relevant authority). The Grantee also hereby agrees to indemnify and keep indemnified the Company and (if different) the Grantee’s employer against any Tax-Related Items that they are required to pay or withhold or have paid or will pay on the Grantee’s behalf to HMRC (or any other tax authority or any other relevant authority).

Notwithstanding the foregoing, if the Grantee is a director or executive officer (as within the meaning of Section 13(k) of the U.S. Securities Exchange Act of 1934, as amended), the terms of the immediately foregoing provision will not apply. In the event that the Grantee is a director or executive officer and income tax due is not collected from or paid by the Grantee within 90 days after the U.K. tax year in which an event giving rise to the indemnification described above occurs, the amount of any uncollected tax may constitute a benefit to the Grantee on which additional income tax and national insurance contributions may be payable. The Grantee acknowledges that he or she ultimately will be responsible for reporting and paying any income tax due on this additional benefit directly to HMRC under the self-assessment regime and for reimbursing the Company or the Grantee’s employer (as applicable) for the value of any employee national insurance contributions due on this additional benefit, which the Company and/or the Grantee’s employer may recover from the Grantee at any time thereafter by any of the means referred to in Paragraph 6 of the Agreement.
