This instrument and the Customizing Information are collectively referred to as the “Performance Unit Agreement.”

WITNESSETH THAT:

WHEREAS, the Company has instituted the Plan; and

WHEREAS, the Compensation Committee (the “Committee”) has authorized the grant of performance units ("PUs") with respect to shares of common stock, par value $0.01 per share, of the Company (“Common Stock”) upon the terms and conditions set forth below and pursuant to the Plan, a copy of which is incorporated herein; and

WHEREAS, the Participant acknowledges that the Participant has carefully read this Performance Unit Agreement and agrees, as provided in Section 19(a) below, that the terms and conditions of the Performance Unit Agreement reflect the entire understanding between the Participant and the Company regarding this performance unit award (and the Participant has not relied upon any statement or promise other than the terms and conditions of the Performance Unit Agreement with respect to this performance unit award);

NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements herein contained and for other good and valuable consideration the receipt and adequacy of which are hereby acknowledged, the Company and the Participant agree as follows. For purposes of this Performance Unit Agreement, to the extent the Participant is not employed by the Company, “Employer” shall mean the subsidiary of the Company that employs or has otherwise engaged the Participant to perform services on its behalf.

1. Grant. Subject to the terms of the Plan and this Performance Unit Agreement, the Company hereby conditionally grants to the Participant that number of PUs to the corresponding number of shares of Common Stock (the “Underlying Shares”) shown in the Customizing Information under “Performance Units Granted.”

The grant described in the preceding paragraph is contingent upon the satisfaction of the “Performance Criteria” over the “Performance Period,” each as shown in the Customizing

Version 7 - Performance Unit Agreement 2/4/2025

Information. The Committee shall determine whether such Performance Criteria have been satisfied.

2. Adjustment to Award. The number of PUs granted may be increased or decreased, including to zero, based on the “Performance Criteria” shown in the Customizing Information. Whether any adjustment based on the Performance Criteria is made shall be determined in the sole discretion of the Committee and the “Adjusted Performance Units Granted” in the Customizing Information shall be updated to reflect any such adjustment.

3. Vesting.

(a) In General. If the Participant remains in an employment, contractual or other service relationship with the Company or a subsidiary of the Company (“Relationship”) as of the “Vesting Date” specified in the Customizing Information, and the Participant as of such date is not in violation of any confidentiality, inventions, non-solicitation and/or non-competition agreement with the Company (to the extent such agreement is permitted under applicable law), the PUs shall vest on such date, based on achievement of the Performance Criteria over the Performance Period. For the avoidance of doubt, except as otherwise provided pursuant to the terms of the Plan and Sections 3(b), 3(c) or 3(d) of this Performance Unit Agreement, if applicable, if the Participant’s Relationship is terminated for any reason, whether voluntarily or involuntarily, no PUs granted pursuant to this Performance Unit Agreement shall vest under any circumstances on and after the date of such termination.

(b) Retirement Vesting. Notwithstanding Section 3(a), if the Participant’s Relationship terminates on account of Retirement (as defined below) on or after the sixth (6th) month anniversary of the Grant Date, the PUs shall remain outstanding and continue to vest based on achievement of the Performance Criteria over the Performance Period provided the Participant continues to comply with any confidentiality, inventions, non-solicitation and/or non-competition agreement with the Company (to the extent such agreement is permitted under applicable law. Notwithstanding any other provision in this Performance Unit Agreement, Retirement-eligible employees are entitled to Retirement treatment even if separated as a result of the death or disability of the Participant.

Any PUs that vest as a result of this Section 3(b) shall be delivered as of the Vesting Date as described in Section 5, provided that no PUs shall be delivered if the Participant as of the date of delivery is in violation of any confidentiality, inventions, non-solicitation and/or non-competition agreement with the Company (to the extent such agreement is permitted under applicable law). “Retirement” means a termination of the Participant’s Relationship after the Participant has attained age fifty-five (55), has five (5) Years of Credited Service and has a combined age and Years of Credited Service of at least sixty-five (65). “Years of Credited Service” shall mean the Participant’s years of total adjusted service with the Company, calculated from the Participant’s initial hire date with the Company (or any predecessor business acquired by the Company) and without regard to any lapses in active employment while employed by the Company, such as approved leaves of absences.

If the Participant is a local national of and employed in a country that is a member of the European Union, the grant of PUs and the terms and conditions governing the PUs are intended to comply with the age discrimination provisions of the EU Equal Treatment Framework Directive, as implemented into local law (the "Age Discrimination Rules"). To the extent that a court or tribunal of competent jurisdiction determines that any provisions of this Performance Unit Agreement are invalid or unenforceable, in whole or in part, under the Age Discrimination Rules, the Company, in its sole discretion, shall have the power and authority to revise or strike such provision to the minimum extent necessary to make it valid and enforceable to the full extent permitted under local law.

(c) Death or Disability Vesting. Notwithstanding Section 3(a), if the Participant’s Relationship terminates as a result of the Participant's disability (as determined by the Board on the basis of medical advice satisfactory to it) or death, the Participant shall become vested in the Participant's Performance Units Granted in accordance with the following schedule:

Date Relationship Terminates Vesting Percentage

On or after first (1st) anniversary of Grant Date 33.3%

On or after second (2nd) anniversary of Grant Date 66.6%

On or after third (3rd) anniversary of Grant Date 100%

No Performance Units Granted that vest as a result of this Section 3(c) shall be delivered if the Participant as of the date of delivery is in violation of any confidentiality, inventions, non-solicitation and/or non-competition agreement with the Company (to the extent such agreement is permitted under applicable law). For the avoidance of doubt, the Performance Criteria shall be treated as satisfied (or satisfied at target, if applicable) and no adjustment shall be made pursuant to Section 2.

(d) Committee Discretion. In the event the Participant’s Relationship is terminated for any reason and except as otherwise provided in Section 3(b) or 3(c), as applicable, (i) the Participant’s right to vest in any PUs will, except as provided in Section 9(c) of the Plan, terminate as of the date of the termination of the Relationship (and will not be extended by any notice period, e.g., a period of “garden leave” or similar period mandated under local law) and (ii) the Committee shall have the exclusive discretion to determine when the Relationship has terminated for purposes of this PU (including when the Participant is no longer considered to be providing active service while on a leave of absence).

4. Dividend Equivalents. A Participant shall be credited with dividend equivalents equal to the dividends the Participant would have received if the Participant had been the actual record owner of the Underlying Shares on each dividend record date on or after the Grant Date and through the date the Participant receives a settlement pursuant to Section 5 below (the “Dividend Equivalent”). If a dividend on the Stock is payable wholly or partially in Stock, the Dividend Equivalent representing that portion shall be in the form of additional PUs, credited on a one-for-one basis. If a dividend on the Stock is payable wholly or partially in cash, the Dividend Equivalent representing that portion shall also be in the form of cash and a Participant shall be treated as being credited with any cash dividends, without earnings, until settlement pursuant to Section 5 below. If a dividend on Stock is payable wholly or partially in other than

cash or Stock, the Committee may, in its discretion, provide for such Dividend Equivalents with respect to that portion as it deems appropriate under the circumstances. Dividend Equivalents shall be subject to the same terms and conditions as the PUs originally awarded pursuant to this Performance Unit Agreement, and they shall vest (or, if applicable, be forfeited) as if they had been granted at the same time as the original PU. Dividend Equivalents representing the cash portion of a dividend on Stock shall be settled in cash.

5. Delivery of Underlying Shares or Cash Settlement.

(a) With respect to any PUs that become vested pursuant to Section 3 (other than Section 3(c)), the Company shall issue and deliver to the Participant (i) the number of Underlying Shares equal to the number of vested PUs or an amount of cash equal to the Fair Market Value, as defined in the Plan, of such Underlying Shares as of the Vesting Date and (ii) the amount (and in the form) due with respect to the Dividend Equivalents applicable to such Underlying Shares. Delivery shall be made to the Participant as soon as practicable following the Vesting Date but in no event later than the end of the year in which such Vesting Date occurs (or the fifteenth (15th) day of the third (3rd) month following the Vesting Date, if later).

(b) With respect to any PUs that become vested pursuant to Section 3(c), the Company shall issue and deliver to the Participant (i) the number of Underlying Shares equal to the number of vested PUs or an amount of cash equal to the Fair Market Value, as defined in the Plan, of such Underlying Shares as of the date of disability or death and (ii) the amount (and in the form) due with respect to the Dividend Equivalents applicable to such Underlying Shares. Delivery shall be made to the Participant as soon as practicable following the date of disability or death but in no event later than the end of the year in which disability or death occurs (or the fifteenth (15th) day of the third (3rd) month following the date of disability or death, if later).

(c) Whether Underlying Shares, or the cash value thereof, shall be issued or paid at settlement shall be determined based on the “Form of Settlement” specified in the Customizing Information.

(d) Any shares issued pursuant to this Performance Unit Agreement shall be issued, without issue or transfer tax, by (i) delivering a stock certificate or certificates for such shares out of theretofore authorized but unissued shares or treasury shares of its Stock as the Company may elect or (ii) issuance of shares of its Stock in book entry form; provided, however, that the time of such delivery may be postponed by the Company for such period as may be required for it with reasonable diligence to comply with any applicable requirements of law.

(e) Notwithstanding the preceding provisions of this Section 5, delivery of Underlying Shares shall be made, or the amount of cash equivalent thereto shall be paid, only if the required purchase price designated as the “Purchase Price” shown in the Customizing Information per unit/share is paid to the Company by means of payment acceptable to the Company in accordance with the terms of the Plan. If the Participant fails to pay for or accept delivery of all of the shares, the right to shares of Stock provided pursuant to this Agreement Performance Unit Agreement may be terminated by the Company.

6. Responsibility for Taxes.

(a) The Participant acknowledges that, regardless of any action taken by the Company or the Employer, the ultimate liability for all income tax (including federal, state, local or and non-US tax), social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to the Plan and legally applicable to the Participant or deemed by the Company in its discretion to be an appropriate charge to the Participant even if legally applicable to the Company or the Employer (“Tax-Related Items”) is and remains the Participant’s responsibility and may exceed the amount actually withheld, if any by the Company and/or the Employer. The Participant 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 the PUs and Dividend Equivalents or the Underlying Shares, including, but not limited to, the grant, vesting or settlement of the PUs, the subsequent sale of Underlying Shares acquired pursuant to such settlement and the receipt of any Dividend Equivalents; and (b) do not commit to and are under no obligation to structure the terms of the grant or any aspect of this PUs to reduce or eliminate the Participant’s liability for Tax-Related Items or to achieve any particular tax result. Further, if the Participant is subject to Tax-Related Items in more than one jurisdiction , the Participant acknowledges that the Company and/or the Employer (or former service Participant, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

(b) If the Participant’s country of residence (and/or the country of employment, if different) requires withholding of Tax-Related Items, the Company may withhold any shares of Common Stock otherwise issuable upon vesting that have an aggregate Fair Market Value sufficient to pay the Tax-Related Items required to be withheld (or an equivalent cash amount, where the PUs are settled in cash in the Company’s sole discretion). For purposes of the foregoing, no fractional shares of Stock will be withheld or issued pursuant to the grant of the PUs. If the obligation for Tax-Related Items is satisfied by withholding shares of Stock or a portion of the cash proceeds (where the PUs are settled in cash in the Company’s sole discretion), for tax purposes, the Participant shall be deemed to have been issued the full number of shares of Stock (or the gross amount of the cash payment), notwithstanding that a number of shares of Common Stock (or a portion of cash proceeds) are withheld solely for the purpose of satisfying any withholding obligations for the Tax-Related Items due as a result of any aspect of the Participant’s participation in the Plan. In addition, where the PUs are settled in shares of Common Stock, the Company may, on behalf of the Participant, sell a sufficient number of whole shares of Common Stock issued upon vesting of the PUs having an aggregate Fair Market Value that would satisfy the withholding amount. Alternatively, the Company or the Employer may, in its discretion and subject to applicable law, withhold any amount necessary to pay the Tax-Related Items from the Participant’s regular salary/wages or other amounts payable to the Participant, with no withholding of shares of Common Stock or cash proceeds payable upon vesting, or may require the Participant to submit payment equivalent to the minimum Tax-Related Items required to be withheld by means of certified check, cashier’s check or wire transfer. In the event the withholding requirements for Tax-Related Items are not satisfied through one of the foregoing methods, no shares of Common Stock will be released to the Participant (or the Participant’s estate) upon vesting of the PUs (or no cash payment will be

made where the PUs are settled in cash in the Company’s sole discretion) unless and until satisfactory arrangements (as determined by the Company in its sole discretion) have been made by the Participant with respect to the payment of any such Tax-Related Items. By accepting the PUs, the Participant expressly consents to the withholding methods for Tax-Related Items as provided hereunder and/or any other methods of withholding that the Company or the Employer may take and are permitted under the Plan to meet the withholding and/or other requirements as provided under applicable laws, rules and regulations. All Tax-Related Items related to the PUs shall be the sole responsibility of the Participant.

(c) The Company may withhold or account for Tax-Related Items by considering statutory withholding amounts or other withholding rates, including up to the maximum rate applicable in the Participant’s jurisdiction(s). If the maximum rate is used, the Participant may receive a refund of any over-withheld amount in cash from the Company or the Employer and will have no entitlement to the equivalent amount in Common Stock or, if not refunded, the Participant may be able to seek a refund from the local tax authorities. Further, if the obligation for the Tax-Related Items is satisfied by withholding in Underlying Shares, for tax purposes, the Participant will be deemed to have been issued the full number of Underlying Shares subject to the vested PUs, notwithstanding that a number of the Underlying 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.

7. Non-assignability of PUs and Dividend Equivalents. PUs and Dividend Equivalents shall not be assignable or transferable by the Participant except by will or by the applicable laws of descent and distribution or as permitted by the Committee in its discretion pursuant to the terms of the Plan. During the life of the Participant, delivery of shares of Stock or payment of cash as settlement of PUs and Dividend Equivalents shall be made only to the Participant, to a conservator or guardian duly appointed for the Participant by reason of the Participant’s incapacity or to the person appointed by the Participant in a durable power of attorney acceptable to the Company’s counsel.

8. Compliance with Securities Act; Lock-Up Agreement. The Company shall not be obligated to sell or issue any Underlying Shares or other securities in settlement of PUs and Dividend Equivalents hereunder unless the shares of Stock or other securities are at that time effectively registered or exempt from registration under the Securities Act and applicable federal, state, local, provincial or foreign securities, exchange control and other laws and in compliance with all applicable requirements of any stock exchange or national market system in which the Stock may be listed. In the event shares or other securities shall be issued that shall not be so registered, the Participant hereby represents, warrants and agrees that the Participant will receive such shares or other securities for investment and not with a view to their resale or distribution, and will execute an appropriate investment letter satisfactory to the Company and its counsel. The Participant further hereby agrees that as a condition to the settlement of PUs and Dividend Equivalents, the Participant will execute an agreement in a form acceptable to the Company to the effect that the shares shall be subject to any underwriter’s lock-up agreement in connection with a public offering of any securities of the Company that may from time to time apply to

shares held by officers and employees of the Company, and such agreement or a successor agreement must be in full force and effect.

9. Legends. The Participant hereby acknowledges that the stock certificate or certificates (or entries in the case of book entry form) evidencing shares of Stock or other securities issued pursuant to any settlement of an PU or Dividend Equivalent hereunder may bear a legend (or provide a restriction) setting forth the restrictions on their transferability described in Section 8 hereof, if such restrictions are then in effect.

10. Rights as Stockholder. The Participant shall have no rights as a stockholder with respect to any PUs, Dividend Equivalents or Underlying Shares until the date of issuance of a stock certificate (or appropriate entry is made in the case of book entry form) for Underlying Shares and any Dividend Equivalents. Except as provided by Section 4, no adjustment shall be made for any rights for which the record date is prior to the date such stock certificate is issued (or appropriate entry is made in the case of book entry form), except to the extent the Committee so provides, pursuant to the terms of the Plan and upon such terms and conditions it may establish.

11. Effect Upon Employment and Performance of Services. Nothing in this Performance Unit Agreement or the Plan shall be construed to impose any obligation upon the Company or any subsidiary to employ or utilize the services of the Participant or to retain the Participant in its employ or to engage or retain the services of the Participant.

12. Time for Acceptance. Unless the Participant shall evidence acceptance of this Performance Unit Agreement by electronic or other means prescribed by the Committee within sixty (60) days after its delivery, the PUs and Dividend Equivalents shall be null and void (unless waived by the Committee).

13. Breach of Restrictive Covenants. In the event that the Participant breaches any confidentiality, inventions, non-solicitation and/or non-competition agreement with the Company and such agreement is permitted by applicable laws, (i) the Participant shall forfeit (and shall not vest in) all PU awards to the extent stock certificates (or appropriate entry in the case of book entry form), cash or other property, as applicable, have not yet been delivered with respect to any PU and (ii) the Participant shall pay to the Company an amount equal to the excess of the Fair Market Value of the Underlying Shares as of the date of settlement (whether settled in cash or Stock) over the Purchase Price, if any, paid (or deemed paid) together with the value of any Dividend Equivalents; provided, however, that the Committee in its discretion may release the Participant from the requirement to make such payment, if the Committee determines that the Participant’s breach of such agreement is not inimical to the best interests of the Company. In accordance with applicable law, the Company may deduct the amount of payment due under the preceding sentence from any compensation or other amount payable by the Company to the Participant. For purposes of this Section 13, the term “Company” refers to the Company as defined in the last sentence of Section 1 of the Plan.

14. Section 409A of the Internal Revenue Code. The PUs and Dividend Equivalents granted hereunder are intended to avoid the potential adverse tax consequences to the Participant

of Section 409A of the Code, and the Committee may make such modifications to this Performance Unit Agreement as it deems necessary or advisable to avoid such adverse tax consequences. If and to the extent that the PUs and Dividend Equivalents are subject to Section 409A, in addition to the provisions of Section 12(f) of the Plan, any payment upon termination of the Relationship shall be made only upon a “separation from service” under Section 409A, and the Participant may not directly or indirectly designate the calendar year of a payment.

15. 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 or to request the Participant’s consent to participate in the Plan by electronic means. The Participant 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 a third party designated by the Company.

16. Company Clawback Policy; Recoupment Requirements. The PUs and Dividend Equivalents granted hereunder shall be subject to any applicable clawback or recoupment policies, share trading policies, corporate governance standards and other policies that may be implemented by the Board from time to time, in accordance with applicable law. Notwithstanding anything in this Performance Unit Agreement to the contrary, the Participant acknowledges and agrees that this Performance Unit Agreement and the award described herein are (a) subject to the terms and conditions of the Company’s clawback or similar compensation recoupment policy as may be in effect from time to time, and (b) subject to deduction, recoupment or forfeiture to the extent required to comply with any recoupment requirement imposed under applicable laws, rules, regulations or stock exchange listing standards, any of which could in certain circumstances require repayment or forfeiture of the PUs or other cash or property received with respect to the PUs (including any value received from a disposition of the PUs). In order to satisfy any recoupment obligations arising under the Company’s compensation clawback policy or otherwise under applicable laws, rules, regulations or stock exchange listing standards, among other things, the Participant expressly and explicitly authorizes the Company to issue instructions on the Participant’s behalf to any brokerage firm or stock plan service provider engaged by the Company to hold any shares of Stock or other amounts acquired pursuant to the PUs to re-convey, transfer or otherwise return such shares and/or other amounts to the Company upon the Company’s enforcement of the compensation clawback or similar policy or any other recoupment obligations.

17. Nature of Award. By accepting this PU, the Participant acknowledges, understands and agrees that:

(iv) no claim or entitlement to compensation or damages shall arise from forfeiture of the PU, including any Dividend Equivalents, resulting from the Participant’s termination of the Relationship (for any reason and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where the Participant is employed or the terms of the Participant’s employment or service agreement, if any) or enforcement of any applicable clawback policy or recoupment requirements applicable to the PUs or Underlying Shares or other benefits or payments relating to the PUs.

The Appendix constitutes part of this Performance Unit Agreement.

(b) The Company reserves the right to impose other requirements on the Participant’s participation in the Plan, on the PUs and on any Underlying Shares to the extent the Company determines it is necessary or advisable for legal or administrative reasons and provided the imposition of the term or condition will not result in any adverse accounting expense to the Company, and to require the Participant to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

(g) Data Privacy Notice and Consent. The Company is located in the United States of America and grants PUs under the Plan to employees of the Company and its subsidiaries in its sole discretion. In conjunction with the Company’s grant of the PUs under the Plan and its ongoing administration of such awards, the Company is providing the following information about its data collection, processing and transfer practices (“Personal Data Activities”). In accepting the grant of the PUs, the Participant expressly and explicitly consents to the Personal Data Activities as described herein.

(i)Data Collection, Processing and Usage. The Company collects, processes and uses the Participant’s personal data, including the Participant’s name, home address, email address, and telephone number, date of birth, social insurance/passport number or other identification number (e.g. resident registration number), salary, citizenship, job title, any shares of Common Stock or directorships held in the Company, and details of all PUs or any other equity compensation awards granted, canceled, exercised, vested, or outstanding in the Participant’s favor, which the Company receives from the Participant or the Employer (“Personal Information”). In granting the PUs under the Plan, the Company will collect the

Participant’s Personal Information for purposes of allocating shares of Common Stock and implementing, administering and managing the Plan. The Company’s legal basis for the collection, processing and usage of the Participant’s Personal Information is the Participant’s consent.

(ii)Stock Plan Administration Service Provider. The Company transfers the Participant’s Personal Information to Fidelity Stock Plan Services LLC, an independent service provider based in the United States, which assists the Company with the implementation, administration and management of the Plan (the “Stock Plan Administrator”). In the future, the Company may select a different Stock Plan Administrator and share the Participant’s Personal Information with another company that serves in a similar manner. The Stock Plan Administrator will open an account for the Participant to receive and trade shares of Common Stock acquired under the Plan. The Participant will be asked to agree on separate terms and data processing practices with the Stock Plan Administrator, which is a condition to the Participant’s ability to participate in the Plan.

(iii) International Data Transfers. The Company and the Stock Plan Administrator are based in the United States. The Participant should note that the Participant’s country of residence may have enacted data privacy laws that are different from the United States. The Company’s legal basis for the transfer of the Participant’s Personal Information to the United States is the Participant’s consent.

(iv)Voluntariness and Consequences of Consent Denial or Withdrawal. The Participant’s participation in the Plan and the Participant’s grant of consent is purely voluntary. The Participant may deny or withdraw the Participant’s consent at any time. If the Participant does not consent, or if the Participant later withdraws the Participant’s consent, the Participant may be unable to participate in the Plan. This would not affect the Participant’s existing employment or salary; instead, the Participant merely may forfeit the opportunities associated with the Plan.

(v)Data Subject Rights. The Participant may have a number of rights under the data privacy laws in the Participant’s country of residence. For example, the Participant’s rights may include the right to (i) request access or copies of personal data the Company processes, (ii) request rectification of incorrect data, (iii) request deletion of data, (iv) place restrictions on processing, (v) lodge complaints with competent authorities in the Participant’s country of residence, and/or (vi) request a list with the names and addresses of any potential Participants of the Participant’s Personal Information. To receive clarification regarding the Participant’s rights or to exercise the Participant’s rights, the Participant should contact the Participant’s local human resources department.

(h) 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 of sale of Underlying Shares. The Participant is hereby advised to consult with the Participant’s own personal tax, legal and financial advisors regarding participation in the Plan before taking any action related to the Plan.

(i) Severability. The provisions of this Performance Unit 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.

Securities Law Information. The Participant is permitted to sell Underlying Shares acquired upon the vesting and settlement of the PUs through the designated broker appointed under the Plan, if any, provided the resale of Underlying Shares acquired under the Plan takes place outside of Canada through the facilities of a stock exchange on which the shares of Stock are listed. The Underlying Shares are currently listed on the New York Stock Exchange.

Foreign Asset/Account Reporting Information. Specified foreign property, including the PUs, Underlying Shares, and other rights to receive shares of a non-Canadian company held by a Canadian resident generally must be reported annually on a Form T1135 (Foreign Income Verification Statement) if the total cost of the foreign property exceeds C$100,000 at any time during the year. Thus, the unvested portion of the PUs must be reported – generally at a nil cost – if the C$100,000 cost threshold is exceeded because the Participant holds other specified foreign property. When Underlying Shares are acquired, their cost generally is the adjusted cost base (“ACB”) of the Underlying Shares. The ACB ordinarily will equal the fair market value of the Underlying Shares at the time of acquisition, but if the Participant owns other shares of Stock, the ACB may need to be averaged with the ACB of the other shares of Stock. The Participant should consult with the Participant’s personal advisor(s) regarding any personal foreign asset/foreign account tax obligations the Participant may have in connection with the Participant’s participation in the Plan.

Unless the PUs and/or the Underlying Shares are registered with the CMF, a public offering of such securities cannot be made in Chile.

No tax payment duties arise if the amount of the foreign financial assets tax calculated on all financial assets held abroad does not exceed a certain threshold.

Foreign Asset Tax. The value of any shares of Common Stock (and other financial assets) held outside Italy by individuals resident of Italy may be subject to a foreign asset tax. The taxable amount will be the fair market value of the financial assets (e.g., Shares) assessed at the end of the calendar year. The value of financial assets held abroad must be reported in Form RM of the annual return. The Participant should consult with the Participant’s personal advisor(s) regarding any personal foreign asset/foreign account tax obligations the Participant may have in connection with the Participant’s participation in the Plan.

Warning This is a grant of performance units (PUs). If the PUs vest, in accordance with the terms of the Plan, the Participant will receive shares of Common Stock or a cash settlement. The shares will give the Participant a stake in the ownership of the Company. The Participant may receive a return if dividends are paid. If the Company runs into financial difficulties and is wound up, the Participant will be paid only after all creditors and holders of any preference shares have been paid. The Participant may lose some or all of the Participant’s investment. New Zealand law normally requires people who offer financial products to give information to investors before they invest. This information is designed to help investors to make an informed decision. The usual rules do not apply to this offer because it is made under an employee share purchase scheme. As a result, the Participant may not be given all the information usually required. The Participant will also have fewer other legal protections for this investment. Ask questions, read all documents carefully, and seek independent financial advice before committing the Participant’s self. The PUs are not listed. The shares of Common Stock are listed on the New York Stock Exchange (NYSE). This means the Participant may be able to sell the shares, if received on vesting of the PUs, on the NYSE if there are interested buyers. The Participant may get less than the Participant invested. The price will depend on the demand for the shares. The Participant have the right to receive from the Company on request, free of charge, a copy of the Company’s latest annual report, financial statements and audit report on those financial statements. The Participant can obtain a copy of these documents electronically at the following website address ▇▇▇▇://▇▇▇▇▇▇▇▇▇.▇▇▇▇▇▇▇▇▇▇▇▇.▇▇▇/▇▇▇▇▇▇▇/▇▇▇-▇▇▇▇▇▇▇▇▇/▇▇▇▇▇▇▇▇▇-▇▇▇▇▇▇▇▇/▇▇▇▇▇▇▇.▇▇▇▇ or by emailing our Investor Relations department at ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇@▇▇▇▇▇▇▇▇▇▇▇▇.▇▇▇.
