Notwithstanding anything herein to the contrary, this Agreement shall be subject to and governed by all the terms and conditions of the Plan, which is incorporated herein by reference, including the powers of the Administrator set forth in Section 2(b) of the Plan. Capitalized terms in this Agreement shall have the meaning specified in the Plan, unless a different meaning is specified herein.

0.Xxx Withholding.

(a)The Grantee acknowledges that, regardless of any action taken by the Company or the Service Recipient, the ultimate liability for all income tax, 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”) is and remains the Grantee’s responsibility and may exceed the amount actually withheld by the Company or the Service Recipient. The Grantee further acknowledges that the Company and/or the Service Recipient (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the PSUs, including, but not limited to, the grant or vesting of the PSUs, the subsequent sale of shares of Stock acquired pursuant to such vesting and the receipt of any dividends; and (2) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the PSUs 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, he or she acknowledges that the Company and/or the Service Recipient (or former Service Recipient, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

(b)Prior to any relevant taxable or tax withholding event, as applicable, the Grantee agrees to make adequate arrangements satisfactory to the Administrator to satisfy all Tax-Related Items. In this regard, the Grantee authorizes and directs the Company to cause its transfer agent and any manager of the Company’s stock plan benefits to sell on the Grantee’s behalf a whole number of shares of Stock from those shares of Stock issued to the Grantee necessary to satisfy the Tax-Related Items withholding obligations. The Grantee acknowledges that the Grantee shall have no control over the timing of such mandatory sale, and the Company shall use the proceeds from such sale to satisfy the Grantee’s liability for Tax-Related Items.

(c)Notwithstanding the foregoing, if such mandatory sale is prevented by a legal, contractual, regulatory or accounting restriction or if the obligation for Tax-Related Items arises other than in connection with the vesting (and associated settlement) of the PSUs, the

Grantee authorizes the Company and/or the Service Recipient, or their respective agents, to satisfy any applicable withholding obligations with regard to all Tax-Related Items by one or a combination of the following: (i) requiring the Grantee to make a payment in a form acceptable to the Company; (ii) withholding from wages or other cash compensation paid to the Grantee by the Company, including director fees, and/or the Service Recipient; (iii) withholding in shares of Stock to be issued upon vesting of the PSUs (provided, in the case of Section 16 officer of the Company subject to Section 16 of the Exchange Act of 1934 (the “Exchange Act”), that this method is authorized by the Administrator as constituted in accordance with Rule 16b-3 under the Exchange Act); or (iv) any other method of withholding determined by the Administrator and permitted by applicable law.

(d)Depending on the withholding method, the Company may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding rates or other applicable withholding rates, including maximum applicable rates in the Grantee’s jurisdiction(s). In the event of over-withholding, the Grantee may receive a refund of any over-withheld amount in cash and will have no entitlement to the equivalent in shares of Stock, or if not refunded, the Grantee may seek a refund from local tax authorities. In the event of under-withholding, the Grantee may be required to pay additional Tax-Related Items directly to the applicable tax authority or to the Company and/or the Service Recipient. If the obligation for Tax-Related Items is satisfied by withholding in shares of Stock, for tax purposes, the Grantee is deemed to have been issued the full number of shares of Stock subject to the vested PSUs, notwithstanding that a number of shares of Stock are held back solely for the purpose of paying the Tax-Related Items.

(e)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.

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

00.Xx Obligation to Continue Service Relationship. Neither the Company nor any Service Recipient is obligated by or as a result of the Plan or this Agreement to continue the Grantee in a Service Relationship and neither the Plan nor this Agreement shall interfere in any way with the right of the Company or any Service Recipient to terminate the service of the Grantee at any time.

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.Recoupment Policy. This Award and Agreement shall be subject to the Company’s Policy for Recoupment of Incentive Compensation as may be amended from time to time (“Recoupment Policy") to the extent such policy is applicable to the Grantee. To the extent the Grantee’s Employment Agreement or any other agreement between the Grantee and any Service Recipient, or the Change in Control Severance Plan or any other policy or plan (but excluding the Recoupment Policy) that may apply to the Grantee, contains provisions regarding performance-

based equity that are less favorable to the Grantee than those provided by this Agreement, this Agreement shall govern with respect to this Award. In no event will the Grantee be eligible for duplicative benefits under this Agreement and any other plan, policy or agreement.

13.Personal Data. In order to administer the Plan, perform its obligations under this Agreement, and to implement or structure future equity grants, the Company may collect and process the Grantee’s personal data, including sharing it with its subsidiaries and affiliates and certain agents thereof (together, the “Relevant Companies”) in connection with administering the Plan and performing its obligations under the Agreement. The Company may also transfer Xxxxxxx’s personal data to countries with privacy laws that may be less protective than those of the Grantee’s country. “Exhibit B,” incorporated by reference into this Agreement, further describes how Xxxxxxx’s personal data will be processed and Xxxxxxx’s rights with respect to personal data processed for the purposes of administering the Plan and this Agreement.

14.Governing Law and Venue. This Award and the provisions of this Agreement are governed by, and subject to, the laws of the State of Delaware, applied without regard to the conflict of law provisions, as provided in the Plan. For purposes of litigating any dispute that arises under this grant or the Agreement, the parties hereby submit to and consent to the jurisdiction of the Commonwealth of Massachusetts, agree that such litigation shall be conducted in the courts of Middlesex County, Massachusetts, or the federal courts for the United States for the District of Massachusetts, where this grant is made and/or to be performed.

15.Notices. Notices hereunder shall be mailed or delivered to the Company at its principal place of business and shall be mailed or delivered to the Grantee at the address on file with the Company or, in either case, at such other address as one party may subsequently furnish to the other party in writing.

16.Electronic Delivery and Acceptance. The Company may, in its sole discretion, decide to deliver any documents related to this Award or future awards that may be granted under the Plan by electronic means. The Grantee 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 another third party designated by the Company.

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.

18.Waiver. The Grantee acknowledges that a waiver by the Company of 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 Grantee or any other grantee.

EXHIBIT A

Performance Multiplier For Performance Cycle

The Performance Multiplier for the Performance Cycle shall be determined as follows:

Total Shareholder Return Percentile Rank within the Performance Measurement Index	Performance Multiplier if Total Shareholder Return is ≥ 0%	Performance Multiplier if Total Shareholder Return is < 0%
100^th Percentile or higher	200%	100%
75^th Percentile	150%	100%
50^th Percentile	100%	100%
25^th Percentile	50%	50%
Below 25^th Percentile	0%	0%

If the Total Shareholder Return for the Performance Cycle ranks between two of the Percentile Ranks above, then the Performance Multiplier shall be determined by using linear interpolation. For purposes of clarity, (i) in no event shall more than 200% of the Target Award be awardable; and (ii) in the event the Total Shareholder Return does not equal or exceed the 25^th percentile, no portion of the Target Award shall be awardable. Notwithstanding anything herein to the contrary, if the Total Shareholder Return in a Performance Cycle is a negative percentage, then in no event shall more than 100% of the Target Award be awardable, even if the Total Shareholder Return would result in a greater percentage pursuant to the table above.

Your personal data will be shared with one or more of the Company’s Subsidiaries, affiliates and certain third-party service providers (“Relevant Companies”) in connection with administering the Plan and performing its obligations under the Agreement.

When sharing your personal data with a third-party service provider, we do so for purposes of administering the Plan and we enter into a contract with the service provider that describes the purposes for sharing your personal data and requires the third-party recipient to protect the confidentiality of and secure the personal data shared, and prohibits use or disclosure of the personal data for any purpose except performing the services under the contract, or as necessary to comply with applicable law.

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, to the extent permitted by the Plan;

the grant of the PSUs is voluntary and occasional and does not create any contractual or other right to receive future grants of all decisions with respect to future or other grants, if any, will be at the sole discretion of the Company;

No Advice Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding the Grantee’s participation in the Plan, or the Grantee’s acquisition or sale of the underlying shares of Stock.

The information is based on the securities, exchange control and other laws in effect in the respective countries as of February 2023. Such laws are often complex and change frequently.

Finally, if the Grantee is a citizen or resident of a country other than the one in which the Grantee is currently residing and/or working (or if the Grantee is considered as such for local law purposes), the information contained herein may not be applicable to the Grantee in the same manner.

Notifications

Foreign Asset/Account Reporting Information. Italian residents who, at any time during the fiscal year, hold foreign financial assets (including cash and shares of Stock) which may generate income taxable in Italy are required to report these assets on their annual tax returns (UNICO Form, RW Schedule, or on a special form if he or she is not required to file a tax return) for the year during which the assets are held. These reporting obligations will also apply to Italian residents who are the beneficial owners of foreign financial assets under Italian money laundering provisions.

Tax on Foreign Financial Assets. Italian residents are subject to a tax on the value of financial assets held outside Italy if the value of such assets exceeds a certain threshold. The taxable amount will be the fair market value of the financial assets (e.g., PSUs, shares of Stock) assessed on December 31 or on the last day of the year that the assets were held (if shares of Stock are acquired or sold during the year, the taxable amount is reduced in proportion to the number of days the shares were held during the calendar year). The tax is assessed as part of the annual tax return.

SPAIN

Notifications

Foreign Asset/Account Reporting Requirement Information. To the extent the Grantee holds shares of Stock or has a bank account outside of Spain with a value in excess of €50,000 (for each type of asset category) as of December 31 each year, the Grantee will be required to report information on such assets and/or accounts on their tax return Form 720 for such year. After such shares of Stock or accounts are initially reported, the reporting obligation will only apply for subsequent years if the value of any previously-reported shares or accounts increases by more than €20,000 (for each type of asset category) as of each subsequent December 31, or if the Grantee sells shares of Stock or closes a bank account that was previously reported.

Further, the Grantee is required to electronically declare to the Bank of Spain any securities accounts (including brokerage accounts) held abroad, as well as the securities (including shares of Stock acquired under the Plan) held in such accounts, if the value of the transactions for all such accounts during the prior tax year or the balances in such accounts as of December 31 exceed €1,000,000. More frequent reporting is required if such transaction value or account balances exceed €1,000,000.

Labor Law Acknowledgment. This provision supplements Section 2: “Nature of Grant” in Exhibit C:

By accepting the PSUs, the Grantee acknowledges, understands and agrees that the Grantee is voluntarily participating in the Plan and has received a copy of the Plan. The Grantee acknowledges having read and accepts Section 3: “Termination of Service Relationship” of this Agreement, and Section 1: “Nature of Grant” of Exhibit C.

The Grantee understands that the Company, in its sole discretion, has unilaterally, gratuitously and in its sole discretion decided to grant PSUs under the Plan to individuals who may be officers, employees, Non-Employee Directors and other key persons (including Consultants) of the Company and its Subsidiaries. The decision is a limited decision that is entered into upon the express assumption and condition that any grant will not economically or otherwise bind the Company or any of its Subsidiaries or affiliates on an ongoing basis over and above the specific terms of the Plan. Consequently, the Grantee understands that the PSUs are granted on the assumption and condition that neither the PSUs nor the shares of Stock acquired at vesting of the PSUs shall become a part of any employment or other service contract (either with the Company or any of its Subsidiaries or affiliates) nor shall they be considered a mandatory benefit, salary for any purposes (including severance compensation) or any other right whatsoever. Further, the Grantee understands and freely accepts that the future value of the PSUs and shares of Stock is unknown and unpredictable. In addition, the Grantee understands that the grant would not be made to the Grantee but for the assumptions and conditions referred to above; thus, the Grantee 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 PSUs grant shall be null and void.

The Grantee also understands and agrees that subject to any exceptions set forth in Section 3: “Termination of Service Relationship” of this Agreement, in the event of the termination of the Grantee’s Service Relationship for any reason (including the reasons listed below), the PSUs will cease vesting and any entitlement to exercise vested PSUs will start to run immediately effective on the date the Grantee is no longer providing services to the Service Recipient or the Company or any of its Subsidiaries. In particular, the Grantee understands and agrees that any unvested PSUs will be forfeited without entitlement to the underlying shares of Stock or to any amount as indemnification in the event of a termination of the Grantee’s Service Relationship as described in the Agreement prior to vesting of the PSUs by reason of, including but not limited to, resignation, retirement, disciplinary dismissal adjudged to be with cause, disciplinary dismissal adjudged or recognized to be without good cause (e.g., subject to a “despido improcedente”), 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 Service Recipient and under Article 10.3 of the Royal Decree 1382/1985.

Securities Law Information. No “offer of securities to the public,” as defined under Spanish law, has taken place or will take place in the Spanish territory in connection with the grant of the PSUs. The Plan and the Agreement have not been nor will they be registered with the Comisión Nacional del Xxxxxxx de Valores, and do not constitute a public offering prospectus.

UNITED KINGDOM

Terms and Conditions

Responsibility for Taxes. The following provision supplements Section 8: “Tax Withholding” in the Agreement:

Without limitation to Section 8 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 the Service Recipient, as applicable, or by His Majesty’s Revenue & Customs (“HMRC”) (or any other tax authority or any other relevant authority). The Grantee also hereby agrees to indemnify and keep indemnified the Company and the Service Recipient, as applicable, against any Tax-Related Items that they are required to pay or withhold or have paid or will pay to HMRC (or any other tax authority or any other relevant authority) on the Grantee’s behalf.

Notwithstanding the foregoing, if the Grantee is a director or executive officer of the Company (within the meaning of Section 13(k) of the Exchange Act), the Grantee understands that he or she may not be able to indemnify the Company for the amount of any Tax-Related Items not collected from or paid by the Grantee, if the indemnification could be considered to be a loan. In this case, the Tax-Related Items not collected or paid may constitute a benefit to the Grantee on which additional income tax and National Insurance Contributions (“NICs”) may be payable. The Grantee understands that he or she 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 paying to the Company and/or the Service Recipient (as appropriate) the amount of any NICs due on this additional benefit, which may also be recovered from the Grantee by any of the means referred to in Section 8 of the Agreement.

Section 431 Election. If the Grantee is or becomes a director or executive officer of the Company (within the meaning of Section 13(k) of the Exchange Act) prior to vesting of the PSUs, the Company may require, as a condition of participation in the Plan and the settlement of the PSUs, that the Grantee enter into, jointly with the Service Recipient, an election within Section 431 of the U.K. Income Tax (Earnings and Pensions) Act 2003 (“ITEPA 2003”) in respect of computing any tax charge on the acquisition of “restricted securities” (as defined in Sections 423 and 424 of ITEPA 2003) (the “431 Election”). This election will be to treat the shares of Stock acquired pursuant to the vesting of the PSUs as if such shares were not restricted securities (for U.K. tax purposes only) despite the Company's clawback policy under the U.S.

Xxxx-Xxxxx Act of 2010. If the Grantee does not enter into the 431 Election if and when requested by the Company, the Grantee will not be entitled to vest in the PSUs and no shares of Stock will be issued to the Grantee, without any liability to the Company, the Service Recipient or any Subsidiary or affiliate.
