(b) (i) If the Participant incurs a Separation from Service with the Company prior to the end of the Performance Period by reason of death, then (to the extent such Performance Shares have not previously been forfeited) the Performance Shares shall be deemed earned upon death and at the target performance level, without proration, and shall be settled within 2-1/2 months following the Participant’s date of death. The non-retained portion of such Performance Shares shall be forfeited upon the Participant’s Separation from Service.

(ii) If the Participant incurs a Separation from Service with the Company prior to the end of the Performance Period by reason of the Participant’s Normal Retirement, then (to the extent such Performance Shares have not previously been forfeited) the Participant shall remain eligible to earn the Performance Shares, at the performance level certified by

the Committee and without pro ration. Such shares shall be deemed to be earned at the end of the Performance Period and shall be settled at the same time as other Plan participants.

(iii)If the Participant incurs a Separation from Service with the Company prior to the end of the Performance Period by reason of the Participant’s involuntary termination of employment that results in severance or supplemental unemployment payments from the Company, then the Participant shall remain eligible to earn the Performance Shares, at the performance level certified by the Committee but subject to pro ration as described in (v) below.

The non-retained portion of such Performance Shares shall be forfeited upon the Participant’s Separation from Service.

(v) For purposes of paragraphs (iii) and (iv) above, a pro rata share of the Performance Shares shall be determined by multiplying the total number of earned Performance Shares to the extent not previously forfeited, by a fraction, the numerator of which is the total number of calendar days during which the Participant was employed by the Company during the period beginning on the first day of the Performance Period and ending on the Participant’s Separation from Service and the denominator of which is the total number of calendar days during the Performance Period (rounded to the nearest whole number of Performance Shares).

5.Change of Control.

(a)If a Change of Control occurs prior to the end of the Performance Period, and the Participant has not yet earned or forfeited such Participant’s Performance Shares as of the date of such Change of Control, then the amount of the Participant’s outstanding Performance Shares shall be determined as of the Change of Control in an amount equal to the Change of Control Value. The “Change of Control Value” shall mean the volume weighted average price of the Company’s common stock on the New York Stock Exchange for the five business days immediately preceding the closing date of the Change of Control multiplied by the number of Performance Shares that would have been earned for the full Performance Period, based on the greater of (1) Company performance for the Performance Period against the target performance, calculated as if the Performance Period ended on the last day of the Company’s fiscal period that ended immediately preceding the date of the Change of Control and (2) Company performance at the targeted level for the Performance Period. In addition, the Performance Shares shall

be subject to the following terms set forth below, as applicable. As used below, “Replacement Award” means an award (A) that vests or is earned based solely on the passage of time and has a value equal to the Change of Control Value, (B) that relates to U.S. publicly traded equity securities of the Successor Company in the Change of Control, (C) the tax consequences of which for such Participant under the Code, if the Participant is subject to U.S. federal income tax under the Code, are not less favorable to the Participant than the tax consequences of the Replaced Award, and (D) the other terms and conditions of which are not less favorable to the Participant than the terms and conditions of the Replaced Award (including the provisions that would apply in the event of a subsequent change of control). A Replacement Award may be granted only to the extent it does not result in the Replaced Award or Replacement Award failing to comply with or ceasing to be exempt from Code Section 409A. Without limiting the generality of the foregoing, the Replacement Award may take the form of a continuation of the Replaced Award if the requirements of the preceding two sentences are satisfied. The determination of whether the conditions of this paragraph are satisfied will be made in good faith by the Committee, as constituted immediately before the Change of Control, in its sole discretion.

(b) If no Replacement Award is provided to the Participant to replace, continue or adjust the Participant’s outstanding Performance Shares (the “Replaced Award”), the Participant will be deemed to have earned, as of the Change of Control, a cash payment equal in value to the Change of Control Value. Such cash payment, when made, will be in full satisfaction of the Performance Shares to which such payment relates. Such earned cash payment shall be paid to the Participant on the date of the Change of Control; provided, however, that if such Change of Control would not qualify as a permissible date of distribution under Code Section 409(a)(2)(A)(v), and the regulations thereunder, and where Code Section 409A applies to such distribution, the Participant will receive such earned cash payment on the date that would have otherwise applied pursuant to this Agreement as though such Change of Control had not occurred.

(c) If a Replacement Award is provided to the Participant to replace, continue or adjust the Replaced Award and the Participant continues employment with the Successor Company after the Change of Control through the end of the Performance Period, the Replacement Award will be deemed earned at the end of the Performance Period. The settlement of the earned Replacement Award shall be made in the shares of stock provided for in such Replacement Award during the calendar year in which the Performance Period ends and in full satisfaction of such Replacement Award.

(d) If a Replacement Award is provided to the Participant to replace, continue or adjust the Replaced Award and the Participant continues employment with the Successor Company after the Change of Control, but the Participant dies prior to the end of the Performance Period, the Replacement Award will be deemed earned as of the Participant’s death. The settlement of the earned Replacement Award shall be made in the shares of stock provided for in such Replacement Award within 2-1/2 months following the Participant’s date of death and in full satisfaction of such Replacement Award.

(e) Notwithstanding anything in this Agreement to the contrary, if a Replacement Award is provided to the Participant to replace, continue or adjust the Replaced Award and

(A) the Participant’s employment with the Successor Company is terminated by the Participant for Good Reason (as defined in the Participant’s employment agreement with the Company or the Letter of Agreement) or by the Successor Company other than for Cause, (B) the Participant terminates employment due to Normal Retirement, or (C) the Participant’s employment with the Successor Company is terminated due to Disability, in each case within a period of two years after the Change of Control but prior to the end of the Performance Period, the Replacement Award shall be deemed 100% earned at the end of the Performance Period.

The Participant will be paid such earned Replacement Award in shares of stock provided for under such Replacement Award during the calendar year in which the Performance Period ends and in full satisfaction of such Replacement Award.

(f) If a Replacement Award is provided, notwithstanding anything in this Agreement to the contrary, any outstanding Performance Shares that, at the time of the Change of Control, are not subject to a “substantial risk of forfeiture” (within the meaning of Code Section 409A) shall be deemed to be earned at the time of such Change of Control and shall be paid in accordance with Section 5(b)’s payment timing provisions in shares of stock provided for under such Replacement Award in full satisfaction of such Replacement Award.

6.Payment of Taxes Upon Settlement. As a condition of the delivery of payment under this Agreement, the Participant agrees that the Company shall withhold a sufficient number of shares of Stock or cash from such payment for any taxes required to be withheld by the Company under Federal, State or local law as a result of the settlement of the Performance Shares in an amount sufficient to satisfy the minimum amount of taxes that is required to be withheld. To the extent permitted under the Plan, the Committee may allow for additional withholding of taxes.

7.Beneficiary Designation. In the case of the Participant’s death, settlement of the Participant’s Performance Shares will be made to the Participant’s designated beneficiary or, if no beneficiary is so designated, the Participant’s surviving spouse (if married) or estate (if not married).

8.Non-Transferability of Performance Shares. The Performance Shares may not be assigned, transferred, pledged or hypothecated in any manner (otherwise than by will or the laws of descent or distribution) nor may the Participant enter into any transaction for the purpose of, or which has the effect of, reducing the market risk of holding the Performance Shares by using puts, calls or similar financial techniques. The Performance Shares subject to this Agreement may be settled during the lifetime of the Participant only with the Participant or the Participant’s guardian or legal representative. Upon any attempt to transfer, assign, pledge, hypothecate, or otherwise dispose of the Performance Shares or any related rights to the Performance Shares that is contrary to the provisions of this Agreement or the Plan, or upon the levy of any attachment or similar process upon the Performance Shares or such rights, the Performance Shares and such rights shall immediately become null and void.
