Capitalized terms used but not specifically defined herein shall have the meanings specified in the Plan or the Grant Notice.

1.Award. For good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, effective as of the Date of Grant, the Company hereby grants to the Participant the Target Number of PRSUs set forth in the Grant Notice on the terms and conditions set forth in the Grant Notice, this Agreement, and the Plan, which is incorporated herein by reference. In the event of any inconsistency between the Plan and this Agreement, the terms of the Plan shall control. The PRSUs are Other Stock-Based Awards granted pursuant to Section 6(h) of the Plan. To the extent earned and vested, each PRSU represents the right to receive one share of Stock, subject to the terms and conditions set forth in the Grant Notice, this Agreement, and the Plan. Prior to settlement of this Award, the PRSUs and this Award represent an unsecured obligation of the Company. Consistent with the terms of the Plan, all designations, determinations, interpretations, and other decisions under or with respect to the terms of the Plan or the Agreement shall be within the sole discretion of the Committee, and shall be final, conclusive, and binding upon all persons.

2.Vesting of PRSUs.

(a)    Subject to the terms of the Grant Notice and this Agreement, a number of PRSUs up to the Target Number of PRSUs are eligible to become (i) Earned PRSUs, based on the achievement of the applicable performance criteria, which shall be determined by the Committee in its sole discretion, and (ii) Vested PRSUs, based on the Participant’s satisfaction of the service-based vesting conditions, in each case, as set forth in the Grant Notice. Any PRSUs (whether or not they have become Vested PRSUs and including all rights arising from such PRSUs and from being a holder thereof) that have not become Earned PRSUs by the conclusion of the Performance Period will terminate automatically without any further action by the Company and will be forfeited without consideration or notice on the last day of the Performance Period. Except as set forth in the Grant Notice, in the event of the termination of the Participant’s employment prior to the date all PRSUs become Vested PRSUs, all unvested PRSUs (whether or not they have become Earned PRSUs and including all rights arising from such PRSUs and from being a holder thereof) will terminate automatically without any further action by the Company and will be forfeited without consideration or notice on the date of such termination. Notwithstanding the foregoing, in the event of a termination of the Participant’s employment for Cause, (A) all PRSUs that have not become vested, and (B) all PRSUs that have become vested but have not been settled in accordance with Section 4 (in each case, whether or not they have become Earned PRSUs and including all rights arising from such PRSUs and from being a holder thereof) will terminate automatically without any further action by the Company and will be forfeited without consideration or notice on the date of such termination. For the avoidance of

doubt, in the event the Participant is or becomes a member of the Board, the Participant will be considered to have remained continuously employed or engaged by the Company or an Affiliate following the termination of the Participant’s employment with the Company or an Affiliate so long as the Participant is a member of the Board as of the date of such termination.

(b)    Notwithstanding any provision herein to the contrary, in the event of any inconsistency between this Section 2 and any written employment agreement entered into by and between the Participant and the Company or an Affiliate, as applicable, the terms of such employment agreement shall control.

3.Dividend Equivalents. In the event that the Company declares and pays a dividend in respect of its outstanding shares of Stock and, on the record date for such dividend, the Participant holds PRSUs granted pursuant to this Agreement that have not been settled or forfeited as of such record date, the Company shall pay Dividend Equivalents to the Participant in the form of cash in an amount equal to the cash dividends the Participant would have received if the Participant was the holder of record, as of such record date, of the number of shares of Stock related to the portion of the Participant’s PRSUs granted pursuant to this Agreement that have not been settled or forfeited as of such record date, such payment to be made promptly following the date that the Company pays such dividend to its shareholders generally (however, in no event shall the Dividend Equivalents be paid later than 30 days following the date on which the Company pays such dividend).

4.Settlement of PRSUs. Except as otherwise provided in Section 2, PRSUs that have become both Earned PRSUs and Vested PRSUs in accordance with the terms of the Grant Notice shall be settled no later than 60 days following (a) the applicable Vesting Date or (b) if the Performance Achievement Date occurs following the applicable Vesting Date, the Performance Achievement Date; provided, however, that, upon an Early Vesting Event, the PRSUs that have become both Earned PRSUs and Vested PRSUs as of the date of such Early Vesting Event shall be settled within 60 days following such Early Vesting Event; provided, further, that in all cases payment shall be made no later than the 15th day of the third month following the end of the Company’s taxable year in which such PRSUs are no longer subject to a substantial risk of forfeiture. Pursuant to this Section 4, the Company shall deliver to the Participant a number of shares of Stock equal to the number of PRSUs that are both Earned PRSUs and Vested PRSUs as of the applicable date or event, subject to the satisfaction of any tax withholding obligations under Section 5. All shares of Stock issued hereunder shall be delivered either by delivering one or more certificates for such shares to the Participant or by entering such shares in book-entry form, as determined by the Committee in its sole discretion. In the event the Participant would otherwise become vested in a fractional portion of a PRSU (a “Fractional PRSU”) based on the vesting terms set forth in the Grant Notice, the Fractional PRSU shall instead remain unvested until the final vesting date or event provided in the Grant Notice; provided, however, that if the Participant would otherwise vest in a subsequent Fractional PRSU prior to the final vesting date or event for the PRSUs and such Fractional PRSU taken together with a previous Fractional PRSU that remained unvested would equal a whole PRSU, then such Fractional PRSUs shall vest to the extent they equal a whole PRSU. Upon the final vesting date or event, the value of any Fractional PRSUs shall be rounded up to the nearest whole PRSU.

5.Tax Withholding. To the extent that the receipt, vesting or settlement of this Award, including without limitation any payment made pursuant to Section 3 of this Agreement, results in compensation income or wages to the Participant for federal, state, local and/or foreign tax purposes, the Participant shall make arrangements satisfactory to the Company for the satisfaction of obligations for the payment of withholding taxes and other tax obligations relating to this Award, which arrangements include the delivery of cash or cash equivalents or, if permitted by the Committee in its sole discretion, Stock, other property, or any other legal consideration the Committee deems appropriate. If such tax obligations are satisfied through net settlement or the surrender of previously owned Stock, the maximum number of shares of Stock that may be so withheld (or surrendered) shall be determined by the Committee and subject to any applicable Company policy that may be in effect from time to time, without creating adverse accounting treatment for the Company with respect to this Award, as determined by the Committee. The Participant acknowledges that there may be adverse tax consequences upon the receipt, vesting or settlement of this Award or disposition of the underlying shares and that the Participant has been advised, and hereby is advised, to consult a tax advisor. The Participant represents that the Participant is in no manner relying on the Board, the Committee, the Company, or any of its Affiliates or any of their respective managers, directors, officers, employees or authorized representatives for tax advice or an assessment of such tax consequences.

6.Non-Transferability. None of the PRSUs, the Dividend Equivalents or any interest or right therein may be sold, pledged, assigned, or transferred in any manner other than by will or the laws of descent and distribution, unless and until the shares of Stock underlying the PRSUs have been issued, and all restrictions applicable to such shares have lapsed. Neither the PRSUs nor any interest or right therein shall be liable for the debts, contracts or engagements of the Participant or his or her successors in interest or shall be subject to disposition by transfer, alienation, anticipation, pledge, encumbrance, assignment or any other means, whether such disposition be voluntary or involuntary or by operation of law by judgment, levy, attachment, garnishment or any other legal or equitable proceedings (including bankruptcy), and any attempted disposition thereof shall be null and void and of no effect against the Company and its Affiliates, except to the extent that such disposition is expressly permitted by the preceding sentence.

7.Compliance with Applicable Law. Notwithstanding any provision of this Agreement to the contrary, the issuance of shares of Stock hereunder will be subject to compliance with all requirements of applicable law with respect to such securities and with the requirements of any stock exchange or market system upon which the Stock may then be listed. No shares of Stock will be issued hereunder if such issuance would constitute a violation of any applicable law or regulation or the requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, shares of Stock will not be issued hereunder unless  a registration statement under the Securities Act is in effect at the time of such issuance with respect to the shares to be issued,  in the opinion of legal counsel to the Company, the shares to be issued are permitted to be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act, or (c) the Company has attained from any regulatory body having jurisdiction the requisite authority, if any, deemed by the Company’s legal counsel to be necessary for the lawful issuance and sale of any shares of

Stock hereunder. As a condition to any issuance of Stock hereunder, the Company may require the Participant to satisfy any requirements that may be necessary or appropriate to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect to such compliance.

8.Rights as a Stockholder. The Participant shall have no rights as a stockholder of the Company with respect to any shares of Stock that may become deliverable hereunder unless and until the Participant has become the holder of record of such shares of Stock, and no adjustments shall be made for dividends in cash or other property, distributions, or other rights in respect of any such shares of Stock, except as otherwise specifically provided for in the Plan or this Agreement.

9.Execution of Receipts and Releases. Any issuance or transfer of shares of Stock or other property to the Participant or the Participant’s legal representative, heir, legatee or distributee, in accordance with this Agreement shall be in full satisfaction of all claims of such person hereunder. As a condition precedent to such payment or issuance, the Company may require the Participant or the Participant’s legal representative, heir, legatee or distributee to execute (and not revoke within any time provided to do so) a release and receipt therefor in such form as it shall determine appropriate; provided, however, that any review period under such release will not modify the date of settlement with respect to PRSUs.

10.No Right to Continued Employment or Awards. Nothing in the adoption of the Plan, nor the grant of the PRSUs thereunder pursuant to the Grant Notice and this Agreement, shall confer upon the Participant the right to continued employment by the Company or any Affiliate, or any other entity, or affect in any way the right of the Company or any such Affiliate, or any other entity to terminate such employment at any time. The grant of the PRSUs is a one-time benefit and does not create any contractual or other right to receive a grant of Awards or benefits in lieu of Awards in the future.

11.Agreement to Furnish Information. The Participant agrees to furnish to the Company all information requested by the Company to enable it to comply with any reporting or other requirement imposed upon the Company by or under any applicable statute or regulation.

12.Entire Agreement; Amendment. This Agreement, the Grant Notice and the Plan constitute the entire agreement of the parties with regard to the subject matter hereof and contain all the covenants, promises, representations, warranties and agreements between the parties with respect to the PRSUs granted hereby; provided¸ however, that the terms of this Agreement shall not modify and shall be subject to the terms and conditions of any employment, consulting and/or severance agreement between the Company (or an Affiliate or other entity) and the Participant in effect as of the date a determination is to be made under this Agreement. Without limiting the scope of the preceding sentence, except as provided therein, all prior understandings and agreements, if any, among the parties hereto relating to the subject matter hereof are hereby null and void and of no further force and effect. The Committee may, in its sole discretion, amend this Agreement from time to time in any manner that is not inconsistent with the Plan.

13.Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to conflicts of law principles thereof.

14.Successors and Assigns. The Company may assign any of its rights under this Agreement without the Participant’s consent. This Agreement will be binding upon and inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth herein and in the Plan, this Agreement will be binding upon the Participant and the Participant’s beneficiaries, executors, administrators, and the person(s) to whom this Award may be transferred by will or the laws of descent or distribution.

15.Clawback. Notwithstanding any provision in this Agreement, the Grant Notice or the Plan to the contrary, to the extent required by  applicable law and/or  any policy that may be adopted or amended by the Board from time to time, all shares of Stock issued hereunder shall be subject to forfeiture, repurchase, recoupment and/or cancellation to the extent necessary to comply with such law(s) and/or policy.

16.Severability. If a court of competent jurisdiction determines that any provision of this Agreement (or any portion thereof) is invalid or unenforceable, then the invalidity or unenforceability of such provision (or portion thereof) shall not affect the validity or enforceability of any other provision of this Agreement, and all other provisions shall remain in full force and effect.

17.Section 409A. Notwithstanding anything herein or in the Plan to the contrary, the PRSUs granted pursuant to this Agreement are intended to be exempt from the applicable requirements of the Nonqualified Deferred Compensation Rules and shall be limited, construed, and interpreted in accordance with such intent. Notwithstanding the foregoing, the Company and its Affiliates make no representations that the PRSUs provided under this Agreement are exempt from or compliant with the Nonqualified Deferred Compensation Rules and in no event shall the Company or any Affiliate be liable for all or any portion of any taxes, penalties, interest, or other expenses that may be incurred by the Participant on account of non-compliance with the Nonqualified Deferred Compensation Rules. The Participant’s employment or service shall terminate on the date that he or she experiences a “separation from service” as defined under the Nonqualified Deferred Compensation Rules.
