(a) Subject to Section 2(e) below, the Restricted Stock vests quarterly over a period of one (1) year on the first day of each quarter after the quarter that includes the Date of the Award provided that the Participant continues to serve as a Non-Employee Director of the Company or a Subsidiary on the applicable vesting date.

(b) To the extent not previously vested in accordance with this Section 2, in the event that a Change of Control becomes effective while the Participant continues to serve as a Non-Employee Director of the Company or a Subsidiary, the Restricted Stock will vest as to all the Shares as of the effective date of the Change of Control.

(c) To the extent not previously vested in accordance with this Section 2, in the event of the Participant’s death, the Restricted Stock will vest as to all the Shares as of the date thereof.

(e) To the extent not previously vested in accordance with Section 2(a) above, if the Participant’s service as a Non-Employee Director of the Company is terminated for cause as determined by the Committee under the terms of the Plan, the Restricted Stock will terminate immediately and be of no force or effect.

(f) For purposes of this Section 2, the following term shall have the meaning set forth below:

“Disability” means the Participant is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or can be expected to last for a continuous period of not less than 12 months.

Unless permitted by the Committee in accordance with the terms of the Plan, the Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated prior to vesting, other than by will or by the laws of descent and distribution.

(a) This Agreement and the rights of the Participant hereunder are subject to the terms and conditions of the Plan, as the same may be amended from time to time, as well as to such rules and regulations as the Committee may adopt for administration of the Plan. If there is any inconsistency between the terms of this Agreement and the terms of the Plan, the Plan’s terms shall completely supersede and replace the conflicting terms of this Agreement.

The Participant agrees to take all steps the Company determines are necessary to comply with all applicable provisions of federal and state securities law in exercising his or her rights under this Agreement. The Committee shall have the right to impose such restrictions on any of the Restricted Stock as it deems necessary or advisable under applicable federal securities laws, the rules and regulations of any stock exchange or market upon which Shares are then listed or traded, and/or any blue sky or state securities laws applicable to Shares. It is expressly understood that the Committee is authorized to administer, construe, and make all determinations necessary or appropriate to the administration of the Plan and this Agreement, all of which shall be binding upon the Participant.

(c) Vesting of the Restricted Stock will be subject to the Participant satisfying all applicable federal, state, local and foreign taxes. The Company shall have authority to deduct or withhold from all amounts payable to the Participant in connection with the Restricted Stock, or require the Participant to remit to the Company, an amount sufficient to satisfy any applicable taxes required by law.
