WHEREAS, the Committee has authorized and approved the grant of an Award to the Participant that will provide the Participant the opportunity to receive shares of Common Stock upon the settlement of stock units on the terms and conditions set forth in the Plan and this Agreement (“Restricted Stock Units”).

NOW THEREFORE, in consideration of the premises and mutual covenants set forth in this Agreement, the parties agree as follows:

(a)General. One-third (1/3rd) of the Restricted Stock Units shall vest on each of the first three (3) anniversaries of the Date of Grant, subject to the Participant’s continued Service through the applicable vesting date.

(b)Termination of Service. Except as set forth in [this Section 2(b) and ]Section 2(c), upon termination of the Participant’s Service for any reason or no reason, any then unvested Restricted Stock Units will be forfeited immediately, automatically and without consideration. [Notwithstanding the foregoing, upon termination of the Participant’s Service by the Company without Cause or due to the Participant’s death or Disability, in each case, prior to a Change in Control, any Restricted Stock Units that were eligible to vest within the twelve (12) month period following the date of the Participant’s termination of Service shall vest on the date of the Participant’s termination of Service.]1

(c)Change in Control. Upon termination of the Participant’s Service by the Participant for Good Reason, by the Company without Cause or due to the Participant’s death or Disability, in each case, upon or following a Change in Control, all Restricted Stock Units shall vest on the date of the Participant’s termination of Service. For purposes of this Agreement, “Good Reason” [and “Cause”] shall have the meaning[s] set forth in Exhibit A of this Agreement.

(d)Accelerated Vesting. Notwithstanding the forgoing, in the event of a Change in Control, if the acquiring, surviving or successor entity in the Change in Control does not assume, continue or substitute Participant’s unvested Restricted Stock Units, whether or not Participant’s employment is terminated as a result of the Change in Control, all unvested Restricted Stock Units shall become fully vested as of the date of such Change in Control, or if applicable, at such earlier time as may be necessary to allow the Company to settle the Restricted stock Units prior to such Change in Control.

(a)Settlement. The Company shall deliver to the Participant within sixty (60) days following the vesting date of the Restricted Stock Units, a number of shares of Common Stock equal to the aggregate number of Restricted Stock Units that have vested pursuant to Section 2. No fractional shares of Common Stock shall be delivered. The Company may deliver such shares of Common Stock either through book entry accounts held by, or in the name of, the Participant or cause to be issued a certificate or certificates representing the number of shares to be issued in respect of the Restricted Stock Units, registered in the name of the Participant.

(b)Withholding Requirements. The Company shall have the right to deduct or withhold from any shares of Common Stock deliverable under this Agreement, or in its discretion to require the Participant to remit to the Company, amounts necessary to satisfy all federal, state and local taxes required to be withheld in connection with the settlement of the Restricted Stock Units. In addition, subject to Section 16 of the Exchange Act, withholding may be satisfied through an open-market, broker-assisted sales transaction pursuant to which the Company is promptly delivered the amount of proceeds necessary to satisfy the withholding amount, which shall be subject to any terms and conditions imposed by the Committee.

(a)Rights of a Shareholder; Dividend Equivalents. Prior to settlement of the Restricted Stock Units in shares of Common Stock, neither the Participant nor the Participant’s representative will have any rights as a shareholder of the Company with respect to any shares of Common Stock underlying the Restricted Stock Units. If cash dividends or other cash distributions are paid in respect of the shares of Common Stock underlying unvested Restricted Stock Units, then a dividend equivalent equal to the amount paid in respect of one Share shall accumulate and be paid with respect to each unvested Restricted Stock Unit at time of settlement; provided that any dividend equivalent rights granted shall be subject to the same vesting terms as the related Restricted Stock Units.

(b)Transfer Restrictions. The shares of Common Stock delivered hereunder will be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan or 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 any agreement with, or policy of, the Company or the Committee to which the Participant is a party or subject, and the Committee may cause orders or designations to be placed upon the books and records of the Company’s transfer agent to make appropriate reference to such restrictions.

(c)Clawback Policy. The Participant acknowledges that the Participant is subject to the provisions of Section 12 (Forfeiture Events) and Section 14.6 (Trading Policy and Other Restrictions) of the Plan and any compensation recovery, “clawback” or similar policy adopted by the Company from time to time and/or made applicable by law including the provisions of Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection and Act and the rules, regulations and requirements adopted thereunder by the Securities and Exchange Commission and/or any national securities exchange on which the Company’s equity securities may be listed.

(d)Adjustments. In the event of any change with respect to the outstanding shares of Common Stock contemplated by Section 4.4 of the Plan, the Restricted Stock Units may be adjusted in accordance with Section 4.4 of the Plan.

(e)No Right to Continued Service. Nothing in this Agreement or the Plan confers upon the Participant any right to continue in Service for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Company (or any Subsidiary retaining the Participant) or of the Participant, which rights are hereby expressly reserved by each, to terminate his or her Service at any time and for any reason, with or without cause.

The provisions of this Agreement will inure to the benefit of, and be binding upon, the Company and its successors and assigns and upon the Participant, the Participant’s executor, personal representative(s), distributees, administrator, permitted transferees, permitted assignees, beneficiaries, and legatee(s), as applicable, whether or not any such person will have become a party to this Agreement and have agreed in writing to be joined herein and be bound by the terms hereof.

(g)Severability. The provisions of this Agreement are severable, and if any one or more provisions are determined to be illegal or otherwise unenforceable, in whole or in part, then the remaining provisions will nevertheless be binding and enforceable.

(h)Amendment. Except as otherwise provided in the Plan, this Agreement will not be amended unless the amendment is agreed to in writing by both the Participant and the Company.

    IN WITNESS WHEREOF, the Company and the Participant have executed this Restricted Stock Unit Award Agreement as of the dates set forth below.

_________________________________        By: ______________________________

Date:_____________________________        Date: _____________________________

“Good Reason” shall mean the occurrence of any of the following events without the consent of the Participant: (i) a material reduction in the Participant’s base salary (other than a reduction affecting all similarly situated employees, which reduction does not exceed 10% of current base salary), (ii) a material diminution in the Participant’s position and duties, which shall not include a change in reporting structure, or (iii) a requirement that the Participant relocate his or her current office outside a radius of fifty (50) miles from the Participant’s current office location. The Participant may not resign or otherwise terminate his or her employment for any reason set forth above as Good Reason unless the Participant (x) notifies the Company in reasonable detail within sixty (60) days following his or her initial knowledge of an event that would constitute Good Reason, (y) the Company fails to remedy such event within 30 days following receipt of such notice, and (z) the Participant terminates employment within 30 days following the end of such 30-day remedy period. Notwithstanding the foregoing, if the Participant is subject to an employment agreement, consulting agreement, change in control agreement or similar agreement in effect between the Company or an Affiliate that defines Good Reason, then Good Reason shall have the meaning set forth therein, otherwise Good Reason as shall have the meaning defined in this Exhibit A.

[“Cause” means (a) in the case where there is no employment agreement, consulting agreement, change in control agreement or similar agreement in effect between the Company or an Affiliate and the Participant (or where there is such an agreement but it does not define “cause” (or words of like import, which shall include but not be limited to “gross misconduct”)), termination due to a Participant’s (1) failure to substantially perform Participant’s duties or obey lawful directives that, in the good faith judgment of the Company, is likely to significantly injure the reputation, business or a business relationship of the Company or any of its Affiliates, that continues after receipt of written notice from the Company and a ten (10)-day opportunity to cure; (2) gross misconduct or gross negligence in the performance of Participant’s duties; (3) fraud, embezzlement, theft, or any other act of material dishonesty or misconduct; (4) conviction of, indictment for, or plea of guilty or nolo contendere to, a felony or any crime involving moral turpitude; (5) (x) material breach or violation of any agreement with the Company or its Affiliates, including any restrictive covenant agreement applicable to Participant, or (y) significant violation of the code of conduct or similar written policy, including, without limitation, any sexual harassment policy, of the Company or its Affiliates; or (6) other conduct, acts or omissions that, in the good faith judgment of the Company, are likely to significantly injure the reputation, business or a business relationship of the Company or any of its Affiliates; or (b) in the case where there is an employment agreement, consulting agreement, change in control agreement or similar agreement in effect between the Company or an Affiliate and the Participant that defines “cause” (or words of like import, which shall include but not be limited to “gross misconduct”), “cause” as defined under such agreement. With respect to a termination of Service for a non-employee director, Cause means an act or failure to act that constitutes cause for removal of a director under applicable Delaware law. Any voluntary termination of Service by the Participant in anticipation of an involuntary termination of the Participant’s Service for Cause shall be deemed to be a termination for Cause.]2

2 NTD: Include for executive-level employees only. All other employees will be subject to standard definition of Cause in the Plan.
