 5.     Shareholder Rights. You shall not be, nor have any of the
rights or privileges of, a shareholder of the Company in respect of the Shares subject to the Performance Share Units unless and until such Shares have been issued by the Company to you. No adjustment will be made for a dividend or other right for
which the record date is prior to the date the Shares are issued, except as provided in Article 12 of the Plan.     

6.     Transferability. The Performance Share Units may not be assigned, alienated, pledged, attached, sold or
otherwise transferred or encumbered by you other than by will or by the laws of descent and distribution, and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the
Company or any Affiliate. 
 7.     Responsibility for Taxes. 

(a) Regardless of any action the Company, any of its Affiliates or the Participant’s employer (the “Employer”) take with
respect to any or all income tax, social insurance, payroll tax, fringe benefit tax, payment on account or other tax-related items related to your participation in the Plan and legally applicable to you (“Tax-Related Items”), you acknowledge that the ultimate liability for all Tax-Related Items is and remains your responsibility and may exceed the amount, if any,
actually withheld by the Company or the Affiliate, if any. You further acknowledge that the Company and/or the Affiliate (i) make no representations or undertakings regarding the treatment of any
Tax-Related Items in connection with any aspect of the Award, including, but not limited to, the grant, vesting or settlement of the Performance Share Units, the issuance of Shares, the subsequent sale of
Shares acquired pursuant to such issuance and the receipt of any dividends; and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Award to reduce or eliminate your liability for Tax-Related Items or achieve any particular tax result. Further, if you are subject to Tax-Related Items in more than one jurisdiction, you acknowledge that the Company and/or
the Affiliate may be required to withhold or account for Tax-Related Items in more than one jurisdiction. 

(b) Subject to Sections 7(c) and (d) below, your acceptance of this Agreement constitutes your instruction and authorization to your
brokerage firm (or, in the absence of a designated brokerage firm, any brokerage firm determined acceptable to the Company for such purpose) to sell on your behalf the number of whole Shares from those Shares issuable to you upon settlement of the
Performance Share Units as the Company determines to be appropriate to generate cash proceeds sufficient to satisfy any applicable withholding obligation for Tax-Related Items. Such Shares will be sold on the
day the Tax-Related Items are determined or as soon thereafter as practicable. You will be responsible for all brokers’ fees and other costs of sale, which fees and costs may be deducted from the proceeds
of the foregoing sale of Shares, and you agree to indemnify and hold the Company and any brokerage firm selling such Shares harmless from any losses, costs, damages, or expenses relating to any such sale. To the extent the proceeds of such sale
exceed your Tax-Related Items, such excess cash will be deposited into the securities account established with the brokerage firm for the settlement of your Performance Share Units. You acknowledge that the
broker or its designee is under no obligation to arrange for such sale at any particular price, and that the proceeds of any such sale may not be sufficient to satisfy your Tax-Related Items. 

(c) At any time before any taxable or tax withholding event, the Committee may, in its sole discretion, determine that the Company or the
Affiliate will satisfy any tax withholding obligation with respect to the Tax-Related Items by withholding Shares to be issued upon vesting of the Performance Share Units. To the extent the Committee makes
such a determination, you hereby authorize the Company to withhold Shares otherwise issuable upon vesting of the Performance Share Units having a Fair Market Value on the date of vesting equal to the amount sufficient to satisfy the Tax-Related Items.

 (d) In the event that, in the reasonable determination of the Company and/or its Affiliate,
such tax withholding by the sale or withholding of Shares as described in Sections 7(b) and (c) above is problematic under applicable tax or securities law or has materially adverse accounting consequences, you authorize the Company and/or the
Affiliate to satisfy any applicable withholding obligation for Tax-Related Items by withholding from your wages or other cash compensation paid to you by the Company and/or the Affiliate, within legal limits,
or by requiring you to tender a cash payment to the Company or the Affiliate in the amount of the Tax-Related Items. 

(e) The Company or the Affiliate may withhold or account for Tax-Related Items by considering
statutory or other withholding rates, including minimum or maximum rates applicable in your jurisdiction(s). In the event of over-withholding, you may receive a refund of any over-withheld amount in cash (with no entitlement to the equivalent in
Shares) of if not refunded, you may seek a refund from the local tax authorities. In the event of under-withholding, you may be required to pay any additional Tax-Related Items directly to the applicable tax
authority or to the Company and/or the Affiliate. If the obligation for the Tax-Related Items is satisfied by withholding in Shares as described in Section 7(c) above, for tax purposes, you will be deemed
to have been issued the full number of Shares subject to the Performance Share Units, notwithstanding that a number of the Shares are held back solely for the purpose of paying the Tax-Related Items due as a
result of your participation in the Plan. 
 (f) Finally, you agree to pay the Company or the Affiliate any amount of Tax-Related Items that the Company or the Affiliate may be required to withhold as a result of your participation in the Plan or the vesting and settlement of the Performance Share Units that cannot be satisfied by
the means previously described. The Company or the Affiliate may refuse to issue or deliver the Shares or the proceeds of the sale of Shares unless and until you have complied with your obligations related to the
Tax-Related Items described in this Section 7. 
 8.     Nature of the

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

Performance Share Units under the Plan after termination of Continuous Service (regardless of whether the termination is in breach of any employment law in the country where you reside, even if such law is otherwise applicable to your employment
benefits, and whether or not such termination is later found to be invalid) will be measured by the date you cease to be actively employed and/or actively providing services and will not be extended by any notice period mandated under any employment
law in the country where you reside, even if such law is otherwise applicable to your employment benefits (e.g., active employment would not include a period of “garden leave” or similar period); the Committee, in its sole discretion,
