The Restricted Stock Units are subject to all of the terms and conditions in the Plan and in this Restricted Stock Unit Agreement (including its Appendices, including but not limited to the Country-Specific Provisions for Non-U.S. Participants set forth in Appendix A hereto (“Appendix A”)), all of which are incorporated herein in their entirety.

BY MY ELECTRONIC ELECTION TO ACCEPT THIS AWARD, I ACKNOWLEDGE THAT I HAVE READ AND UNDERSTAND THE RESTRICTIVE COVENANTS CONTAINED IN SECTION 7 OF THIS AGREEMENT. I ACKNOWLEDGE THAT THE RESTRICTIVE COVENANTS CONTAINED IN THIS AGREEMENT ARE REASONABLE AND NECESSARY TO PROTECT THE LEGITIMATE BUSINESS INTERESTS OF THE COMPANY AND ITS SUBSIDIARIES AND AFFILIATES.

IF I FAIL TO ACCEPT THE TERMS AND CONDITIONS OF THIS AWARD WITHIN NINETY (90) DAYS OF THE DATE THAT THIS AWARD IS MADE AVAILABLE TO ME ON THE THIRD PARTY ADMINISTRATOR WEBSITE, THE COMPANY MAY DETERMINE THAT THIS AWARD HAS BEEN FORFEITED AND MAY CANCEL THIS AWARD.

TERMS AND CONDITIONS OF RESTRICTED STOCK UNIT AGREEMENT

1.Award. Each Restricted Stock Unit represents the unsecured right to receive one share of Common Stock of the Company (“Share”), subject to certain restrictions and subject to the terms and conditions contained in this Agreement and the Plan. The Company hereby grants to the Participant under the Plan as a separate incentive and not in lieu of any salary or other compensation for his or her services, an Award of Restricted Stock Units as of the Grant Date specified above, subject to all of the terms and conditions in the Agreement and the Plan. For purposes of this Agreement, if the Participant is not employed by the Company, “Employer” means the subsidiary or affiliate that employs the Participant.

2.Settlement; Issuance of Shares. No Shares shall be issued to the Participant prior to the date on which the Restricted Stock Units vest. After any Restricted Stock Units vest pursuant to the vesting schedule set forth in Appendix C, or, if earlier, pursuant to Section 4 below, the Company shall promptly cause to be issued in book-entry form within 30 days of such vesting (provided that any Restricted Stock Units that could qualify for the short-term deferral exception under Section 409A of the Code shall be settled no later than the expiration of the short-term deferral period after they cease to be subject to a substantial risk of forfeiture), registered in the Participant’s name or in the name of Participant’s legal representatives or heirs, as the case may be, Shares in payment of such vested Restricted Stock Units.

Notwithstanding the foregoing, the Company may delay any settlement under this Agreement that the Company reasonably determines would violate any applicable law or an applicable provision of the Plan until the earliest date on which the Company reasonably determines that the making of the settlement will not cause such a violation (in accordance with U.S. Treasury Regulation Section 1.409A-2(b)(7)(ii)).

3.Dividend Equivalents. During the period beginning on the Grant Date and ending on the date that Shares are issued in settlement of vested Restricted Stock Units, the Participant will accrue dividend equivalents on the Restricted Stock Units equal to any cash dividend or cash distribution that would have been paid on the Restricted Stock Unit had that Restricted Stock Unit been an issued and outstanding Share on the record date for the dividend or distribution. Such accrued dividend equivalents (a) will vest and become payable upon the same terms and at the same time of settlement as the Restricted Stock Unit to which they relate (and will be payable with respect to any Shares that are issued or that are withheld in order to satisfy Participant’s Tax-Related Items) and (b) will be delivered in the form of Shares in accordance with the vesting and payment schedules applicable to the underlying Restricted Stock Unit. Dividend equivalent payments, at settlement, will be net of applicable federal, state, local and foreign income and social insurance withholding taxes. Upon the forfeiture of the Restricted Stock Units, any accrued dividend equivalents attributable to such Restricted Stock Units will also be forfeited. On such date that Shares are issued in settlement of vested Restricted Stock Units, any dividend equivalents payable with respect to fractional Shares shall be paid in the form of fractional Shares.

4.Termination of Employment or Service; Disability.

(a)Forfeiture of Unvested Restricted Stock Units. Upon Termination of Service, Other than Death, Disability, Qualifying or Early Retirement. In the event that Participant’s employment by or service to the Company or the Employer is terminated (“Termination of Service”) for any reason other than death, Qualifying or Early Retirement (as defined below) and provided that the Participant has not experienced a Disability as of the Termination of Service, then any unvested Restricted Stock Units shall be forfeited immediately upon such termination date, subject to Section 17 of the Plan.

For purposes of this Award, the Participant’s employment or service with the Company or the Employer will be considered terminated as of the date the Participant is no longer actively providing services to the Company, the Employer or any subsidiary or affiliate (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment or other laws in the jurisdiction where the Participant is employed or otherwise providing services or the terms of the Participant’s employment or other service agreement, if any). Unless the Company determines otherwise (and subject to Section 409A of the Code), the date of Termination of Service for purposes of this Award will not be extended by any notice period (e.g., the Participant’s period of service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where the Participant is employed or otherwise providing services or the terms of the Participant’s employment or other service agreement, if any). The Committee or its delegate shall have the exclusive discretion to determine when the Participant is no longer actively providing services for purposes of the Award (including whether the Participant may still be considered to be providing services while on a leave of absence).

(b)Termination of Employment or Service Due to Death; Disability. In the event of a Termination of Service due to death or in the event of the Participant’s Disability, any unvested Restricted Stock Unit as of the date of the Participant’s death or Disability will immediately vest. For the avoidance of doubt, in the event the Participant experiences death or Disability after a Qualifying or Early Retirement, this Section 4(b) shall not apply, and the applicable provisions of Section 4(c) below shall control.

(c)Termination of Employment or Service Due to Qualifying or Early Retirement.

(i)In the event of a Qualifying Retirement on or after October 1st of this year, the unvested Restricted Stock Units in this Award will continue to vest as if the Participant remained actively employed by the Company, the Employer or any subsidiary or affiliate. For purposes of the foregoing, to be a “Qualifying Retirement”, the following criteria must be met at the time of Termination of Service:

•The Participant has reached age 57;

•The Participant has rendered 10 years of service to the Company and its subsidiary or affiliates; and

•The Termination of Service must not be due to “Cause” as defined in the Plan and not due to death, and the Participant may not have experienced a Disability as of the Termination of Service.

If the Company determines after Termination of Service that circumstances that would have constituted Cause exist (or existed), vesting shall immediately cease and all outstanding Awards shall be forfeited. To the maximum extent permitted by applicable law, the Participant also agrees that the restrictive covenants set forth in Section 7 below are extended during the entirety of the Participant’s continued vesting following a Qualifying Retirement, and that any breach of such covenants will immediately and retroactively result in the forfeiture of the Restricted Stock Units.

(ii)In the event of an Early Retirement on or after the completion of one year of service since the Grant Date, the unvested RSUs with less than twelve months remaining from the vesting date set forth in Annex C to this Agreement will be prorated based on the time the Participant remains actively employed by the Company, the Employer or any subsidiary or affiliate during the entire vesting period. The unvested RSUs with more than twelve months remaining from the vesting date set forth in Annex C to this Agreement shall be forfeited immediately upon such termination date, subject to Section 17 of the Plan. Upon the Participant’s Termination of Service with the Company, the Employer or any subsidiary or affiliate following the Participant’s Early Retirement, the prorated Restricted Stock Units will immediately vest. For purposes of the foregoing, to be an “Early Retirement”, the following criteria must be met at the time of Termination of Service:

•The Participant has a combined age and years of service to the Company and its subsidiary or affiliates equal to 67 years;

•The Participant has reached age 55;

•The Participant has rendered 5 years of service to the Company and its subsidiary or affiliates; and

•The Termination of Service must not be due to “Cause” as defined in the Plan and not due to death, and the Participant may not have experienced a Disability as of the Termination of Service.

If the Company determines after Termination of Service that circumstances that would have constituted Cause exist (or existed), vesting shall immediately cease and all outstanding Awards shall be forfeited. To the maximum extent permitted by applicable law, the Participant also agrees that the restrictive covenants set forth in Section 7 below are extended during the entirety of the Participant’s prorated vesting following an Early Retirement, and that any breach of such covenants will immediately and retroactively result in the forfeiture of the Restricted Stock Units.

5.Committee Discretion. The Committee, in its absolute discretion, may accelerate the vesting of the balance, or some lesser portion of the balance, of the unvested Restricted Stock Units at any time; provided that, the time or schedule of any amount to be settled pursuant to the terms of this Agreement that provides for the deferral of compensation under Section 409A of the Code, may not be accelerated except as otherwise permitted under Section 409A of the Code and Section 19 of the Agreement. If so accelerated, such Restricted Stock Units shall be considered as having vested as of the date specified by the Committee.

6.Responsibility for Taxes & Withholding. Regardless of any action the Company and/or the Employer takes with respect to any or all income tax, social insurance or social security, payroll tax, payment on account or other tax-related items related to the Participant’s participation in the Plan and legally applicable to the Participant (“Tax-Related Items”), the Participant acknowledges that the ultimate liability for all Tax-Related Items is and remains the Participant’s responsibility and may exceed the amount actually withheld by the Company and/or the Employer. The Participant further acknowledges 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 upon settlement of the Restricted Stock Units, the subsequent sale of Shares acquired pursuant to such issuance and the receipt of any dividends and/or dividend equivalents; and (2) do not commit to and are under no obligation to structure the terms of any Award to reduce or eliminate Participant’s liability for Tax-Related Items or achieve any particular tax result. Further, if the Participant becomes subject to tax in more than one jurisdiction between the Grant Date and the date of any relevant taxable event, the Participant acknowledges that the Company and/or the Employer may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

The Participant agrees as a condition of his or her participation in the Plan to make arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, the Company, or their respective agents, will withhold Shares to be issued upon vesting/settlement of the Restricted Stock Units, unless the Company, or if different, the employer, at their discretion, permit the obligations to be satisfied with regard to all Tax-Related Items by one or a combination of the following:

(a)withholding from the Participant’s wages/salary or other cash compensation paid to the Participant by the Company and/or the Employer; or

(b)withholding from proceeds of the Shares acquired upon vesting/settlement of the Restricted Stock Units either through a voluntary sale or through a mandatory sale arranged by the Company (on Participant’s behalf pursuant to this authorization).

Notwithstanding the above, if the Participant is a Section 16 officer of the Company under the Exchange Act of 1934, as amended, then the Company will withhold in Shares upon the relevant taxable or tax withholding event, as applicable, unless the use of such withholding method is problematic under applicable tax or securities law or has materially adverse accounting consequences, in which case, the obligation for Tax-Related Items may be satisfied by one or a combination of methods (a) and (b) above.

To avoid negative accounting treatment, the Company and/or the Employer may withhold or account for Tax-Related Items by considering applicable statutory withholding amounts or other applicable withholding rates (but not in excess of the maximum amount permitted for tax withholding under applicable law). If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, the Participant is deemed to have been issued the full number of Shares attributable to the vested Restricted Stock Units, notwithstanding that a number of Shares are held back solely for the purpose of paying the Tax-Related Items due as a result of any aspect of the Participant’s participation in the Plan.

The Participant shall pay to the Company, or if different, the Employer, any amount of Tax-Related Items that the Company, or if different, the Employer, may be required to withhold or account for as a result of the Participant’s participation in the Plan that will not for any reason be satisfied by the means previously described. The Company may refuse to issue or deliver the Shares or the proceeds of the sale of Shares if the Participant fails to comply with the Participant’s obligations in connection with the Tax-Related Items.

By accepting this grant of Restricted Stock Units, the Participant expressly consents to the methods of withholding Tax-Related Items by the Company, or if different, the Employer as set forth herein, including the withholding of Shares and the withholding from the Participant’s wages/salary or other amounts payable to the Participant. All other Tax-Related Items related to the Restricted Stock Units and any Shares delivered in satisfaction thereof are the Participant’s sole responsibility.

For avoidance of doubt, Section 7(c) of the Agreement shall not apply to Participants who are employed at a California location.

(h)the future value of the underlying Shares is unknown and cannot be predicted with certainty;

(i)the value of the Shares acquired upon settlement of the Restricted Stock Units may increase or decrease in value;

(j)unless otherwise agreed with the Company in writing, the Restricted Stock Units and the Shares subject to the Restricted Stock Units, and the income from and value of same, are not granted as consideration for, or in connection with, the service the Participant may provide as a director of any subsidiary or affiliate;

(k)no claim or entitlement to compensation or damages shall arise from forfeiture of the Restricted Stock Units resulting from the termination of the Participant’s employment or service (for any reason whatsoever whether or not later found to be invalid or in breach of employment laws in the jurisdiction where the Participant is providing services or the terms of the Participant’s employment or other service agreement, if any); and

(l)neither the Company nor any subsidiary or affiliate shall be liable for any foreign exchange rate fluctuation between the Participant’s local currency and the United States Dollar that may affect the value of the Restricted Stock Units or of any amounts due to the Participant pursuant to the settlement of the Restricted Stock Units or the subsequent sale of any Shares acquired upon settlement.

12.No Advice Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding the Participant’s participation in the Plan, or the Participant’s acquisition or sale of the underlying Shares. The Participant should consult with the Participant’s own personal tax, legal and financial advisors regarding the Participant’s participation in the Plan before taking any action related to the Plan.

13.No Right to Continued Employment. Neither the Company, the Employer nor any other subsidiary or affiliate is obligated by or as a result of the Plan or this Agreement to continue the Participant’s employment or service with the Company or the Employer, and neither the Plan nor this Agreement shall interfere in any way with the right of the Company, the Employer or any subsidiary or affiliate, as applicable, to terminate the Participant’s employment or service with the Company or the Employer at any time.

14.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.

15.Data Privacy Consent.

(a)Data Collection and Usage. The Company and the Employer collect, process and use certain personal information about the Participant, including, but not limited to, the Participant’s name, home address, telephone number, email address, date of birth, social insurance number, passport or other identification number, salary, nationality, job title, any Shares or directorships held in the Company, details of all Restricted Stock Units granted under the Plan or any other entitlement to shares of Stock awarded, cancelled, exercised, vested, unvested or outstanding in the Participant’s favor (“Data”), for the legitimate purpose of implementing, administering and managing the Plan. Where required, the legal basis for the collection and processing of Data is the Participant’s consent.

The Company will hold and use Data only as long as is necessary to implement, administer and manage the Participant’s participation in the Plan, or as required to comply with legal or regulatory obligations, including under tax, exchange control, securities and labor laws.

(e)Voluntariness and Consequences of Consent Denial or Withdrawal. Participation in the Plan is voluntary and the Participant is providing the consents herein on a voluntary basis. The Participant understands that the Participant may request to stop the transfer and processing of the Data for purposes of the Participant’s participation in the Plan and that the Participant’s employment or service will not be affected. The only consequence of refusing or withdrawing consent is that the Company would not be able to allow the Participant to participate in the Plan. The Participant understands that the Data will still be processed in relation to the Participant’s employment or service for record-keeping purposes.

(f)Data Subject Rights. The Participant may have a number of rights under data privacy laws in the Participant’s jurisdiction.

Notwithstanding any other provision of the Plan or this Agreement, unless there is an available exemption from any registration, qualification or other legal requirement applicable to the Shares, the Company shall not be required to permit the vesting of the Restricted Stock Units and/or deliver any Shares prior to the completion of any registration or qualification of the Shares under any U.S. or non-U.S. local, state or federal securities or exchange control law or under rulings or regulations of the SEC or of any other governmental regulatory body, or prior to obtaining any approval or other clearance from any local, state, federal or foreign governmental agency, which registration, qualification or approval the Company shall, in its absolute discretion, deem necessary or advisable. The Participant understands that the Company is under no obligation to register or qualify the Shares with the SEC or any U.S. state or non-U.S. securities commission or to seek approval or clearance from any governmental authority for the issuance or sale of the Shares subject to this Restricted Stock Unit. Further, the Participant agrees that the Company shall have unilateral authority to amend this Agreement without the Participant’s consent to the extent necessary to comply with securities or other laws applicable to issuance of the Shares subject to the Restricted Stock Units.

19.Section 409A of the Code for U.S. Taxpayers. This Award is intended to be exempt from or compliant with Code Section 409A and shall be administered and interpreted accordingly. In this regard, to the extent necessary to comply with Code Section 409A, and notwithstanding anything else in this Agreement to the contrary, (i) any reference to “termination of employment,” “Termination of Service,” or similar terms will mean the Participant’s “separation from service” within the meaning of Code Section 409A(a)(2)(A)(i) (a “Separation”) and (ii) any reference to “Disability” will mean a Disability within the meaning of Code Section 409A(a)(2)(c). In addition, if any portion of this Award is payable upon a Separation and the Participant is a “specified employee” of the Company or any subsidiary or affiliate thereof within the meaning of Code Section 409A(a)(2)(B)(i) on the day of the Separation, then no such payment shall be made prior to the date that is the earlier of (i) six months and one day after the Separation, or (ii) the Participant’s death, but only to the extent such delay is necessary so that this Award is not subject to additional tax or interest under Code Section 409A. Each amount to be paid under this Agreement is intended to constitute a separate payment for purposes of Code Section 409A. Notwithstanding the foregoing, the Company makes no representation that any or all of the payments described in this Agreement will be exempt from or comply with Code Section 409A and the Participant understands and agrees that the Participant shall be solely responsible for the payment of any amounts incurred by the Participant on account of non-compliance with Code Section 409A.

20.Electronic Delivery and Participation. The Company may, in its sole discretion, decide to deliver any documents related to current or future participation in the Plan by electronic means. The Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line electronic system established and maintained by the Company or a third party designated by the Company.

23.Imposition of Other Requirements. The Company reserves the right to impose other requirements on the Participant’s participation in the Plan, on the Restricted Stock Units and on the Shares acquired upon the vesting of the Restricted Stock Units, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to require the Participant to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

24.Waiver. The Participant 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 Participant or any other Participant.

25.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.

26.▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Restrictions/Market Abuse Laws.

APPENDIX A

COUNTRY-SPECIFIC PROVISIONS FOR NON-U.S. PARTICIPANTS

Terms and Conditions

This Appendix A includes additional (or, if so indicated, different) terms and conditions that govern the Restricted Stock Units granted to the Participant if the Participant is in one of the countries listed herein.

If the Participant is a citizen or resident of a country (or if the Participant is considered as such for local law purposes) other than the one in which the Participant is currently residing and/or working, or if the Participant transfers employment and/or residency to another country after being granted the Restricted Stock Units, the Company will, in its discretion, determine the extent to which the terms and conditions contained herein will be applicable to the Participant.

Capitalized terms used but not defined herein shall have the same meanings as set forth in the Plan or the Restricted Stock Unit Agreement, as applicable.

Notifications

This Appendix A also includes information regarding certain issues of which the Participant should be aware with respect to his or her participation in the Plan. The information is based on securities, exchange control and other laws in effect in the respective countries as of June 2025. Such laws are often complex and change frequently. As a result, the Participant should not rely on the information in this Appendix A as the only source of information relating to the consequences of participation in the Plan because the information may be out of date at the time the Restricted Stock Units vest or the Participant sells Shares acquired under the Plan.

In addition, the information contained herein is general in nature and may not apply to the Participant’s particular situation, and the Company is not in a position to assure the Participant of a particular result. Accordingly, the Participant should seek appropriate professional advice as to how the relevant laws in his or her country may apply to the Participant’s individual situation.

Finally, if the Participant is a citizen or resident of a country (or if the Participant is considered as such for local law purposes) other than the one in which the Participant is currently residing and/or working, or if the Participant transfers employment and/or residency to another country after being granted the Restricted Stock Units, the information contained herein may not be applicable in the same manner.
