Form of Employee Restricted Stock Unit/Performance Restricted Stock Unit Award Notice

[Performance Vesting

If a Performance Goal is achieved prior to the end of the ____ Performance Period, then the PRSUs associated with the attainment of such attained Goal will vest in full and be earned on each Vesting Date. If a Performance Goal is not achieved by the end of the Performance Period, the PRSUs associated with the attainment of such Goal shall be forfeited and shall not vest. The number of Shares underlying the PRSUs vested and earned shall be adjusted if the Company engages in any stock split, reverse stock split or other capitalization affecting all common stock during the Performance Period.]

Settlement

Upon vesting of all or any portion of the [RSUs][PRSUs], settlement will be made by issuance of the number of Shares equal to the vesting [RSUs][PRSUs].

No Dividend Equivalents

No dividend equivalents are authorized as part of this award of [RSUs][PRSUs].

Withholding

The Participant shall pay to the Company promptly upon request, and in any event at the time the Participant recognizes taxable income in respect of the [RSUs][PRSUs], an amount equal to the federal, state or local taxes the Company determines it is required to withhold with respect to the vesting [RSUs][PRSUs]. Such payment shall be made by check or, for (1) employees other than executive officers, (2) employees not in possession of material non-public information, or (3) employees in jurisdictions that do not allow “sell to cover,” by selling Shares on the open market to cover the tax obligations. Upon approval by the Committee or the Board, the Participant may pay the applicable withholding by having the Company withhold from the Shares which would otherwise be delivered to the Participant hereunder Shares with a Fair Market Value sufficient to satisfy the minimum withholding required with respect thereto to the extent permitted by the Company, or in a combination of such methods, as irrevocably elected by the Participant prior to the applicable tax due date with respect to such [RSUs][PRSUs]. [The net settlement of the Shares underlying the vested [RSUs][PRSUs] and the delivery of Shares previously owned are hereby specifically authorized alternatives for the satisfaction of the foregoing withholding obligation.] The Company provides no advice regarding the availability of “sell to cover” at any specific point in time.

Issuance of Shares

Following the applicable vesting date with respect to the [RSUs][PRSUs], and subject to the terms and conditions of the Plan, the Company will cause to be issued a direct registration/book-entry statement (“DRS”) for the Shares issuable with respect to such vested [RSUs][PRSUs]. Such issuance shall take place as soon as practicable following the applicable vesting date (but in no event later than two and one-half months following the end of the calendar year in which the vesting date occurs). The certificates or DRS representing the Shares issued in respect of the [RSUs][PRSUs] shall be subject to such stop transfer orders and other restrictions as the Committee may determine is required by the rules, regulations, and other requirements of the Securities and Exchange Commission, any stock exchange upon which such Shares are listed, any applicable federal or state laws and the Company’s Certificate of Incorporation and Bylaws, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions.

Transferability of [RSUs][PRSUs]
