No individual will have personal liability by reason of anything done or omitted to be done by the Company or the Committee in connection with the Plan. This limitation of liability shall not be exclusive of any other limitation of liability to which any such person may be entitled under the Company’s Certificate of Incorporation or otherwise.

4.1.    SOURCE OF SHARES FOR THE PLAN. The shares of Stock that may be issued pursuant to the Plan shall be issued under the Omnibus Plan, subject to all of the terms and conditions of the Omnibus Plan. The terms contained in the Omnibus Plan are incorporated into and made a part of this Plan with respect to Restricted Stock Awards pursuant hereto and such Awards shall be governed by and construed in accordance with the Omnibus Plan. In the event of any actual or alleged conflict between the provisions of the Omnibus Plan and the provisions of this Plan, the provisions of the Omnibus Plan shall be controlling and determinative; provided that the provisions of Section 5.4 of this Plan (rather than those of Section 13.6 of the Omnibus Plan) shall control and be determinative in the event of a Change in Control. This Plan does not constitute a separate source of shares for the Awards described herein.

5.1.    INITIAL AWARD OF RESTRICTED STOCK. Subject to share availability under the Omnibus Plan, on the date that a new Non-Employee Director is initially elected or appointed to the Board, such director will receive a Restricted Stock Award. The number of shares of Restricted Stock to be awarded shall be established from time to time by the Board. Unless and until changed by the Board, the number of shares of Restricted Stock to be awarded in each initial Restricted Stock Award shall be determined by dividing $10,000 by the Fair Market Value of one share of Stock as of the award date, and rounding up to the nearest whole share (the “Initial Restricted Stock Award”). Non-Employee Directors shall be eligible to receive both an Initial Restricted Stock Award and an Annual Restricted Stock Award (as defined below) in his or her initial year of service. Such shares of Restricted Stock shall be evidenced by a written Award Notice in the form at the end of this Plan and shall be subject to such restrictions and risk of forfeiture as are described in the form of Award Notice and any other restrictions and terms determined by the Board, and shall be granted under and pursuant to the terms of the Omnibus Plan.

5.2.    ANNUAL AWARD OF RESTRICTED STOCK. Subject to share availability under the Omnibus Plan, on the date of each annual meeting of the Company’s stockholders, each Eligible Participant in service on the close of business on that date shall receive a Restricted Stock Award. The number of shares of Restricted Stock to be awarded shall be established from time to time by the Board. Unless and until changed by the Board, the number of shares of Restricted Stock to be awarded in each annual Restricted Stock Award for a full Plan Year shall be determined by dividing $100,000 by the Fair Market Value of one share of Stock as of the award date, and rounding up to the nearest whole share (the “Annual Restricted Stock Award”). Such shares of Restricted Stock shall be evidenced by a written Award Notice in the form at the end of this Plan and shall be subject to such restrictions and risk of forfeiture as are described in the form of Award Notice and any other restrictions and terms determined by the Board, and shall be granted under and pursuant to the terms of the Omnibus Plan.

5.3.    VESTING. Unless and until provided otherwise by the Board, the Initial Restricted Stock Awards and the Annual Restricted Stock Awards shall vest and all restrictions with respect thereto shall lapse only upon the earliest to occur of: (i) the date that is one (1) year from the date of grant (as determined by Section 5.5 of the Omnibus Plan), but only if the Non-Employee Director is still a director of the Company immediately prior to the election of directors at the annual meeting of stockholders as of such date; (ii) the date that his or her tenure as a director of the Company terminates by reason of death, Disability, resignation effective at an annual meeting of stockholders because he or she is no longer qualified to serve as a director under Section 3.1 of the Bylaws of the Company, or for another approved reason as determined by the Committee; or (iii) the date that his or her tenure as director of the Company terminates by reason of his or her failure to be reelected as a director in an election in which he or she consented to be named as a director nominee (each, a “Vesting Date”). If the grantee’s service as a director of the Company (whether or not in a Non-Employee Director capacity) terminates prior to the first anniversary of the date of grant other than as described in clause (ii) or (iii) of the foregoing sentence, then the grantee shall forfeit all of his or her right, title and interest in and to any unvested shares of Restricted Stock as of the date of such termination from the Board and such shares of Restricted Stock shall be reconveyed to the Company without further consideration or any act or action by the grantee.

5.4.    CHANGE IN CONTROL.

(a)    Vesting of Awards. Upon a Change in Control: (i) the terms of this Section 5.4 shall immediately become operative, without further action or consent by any person or entity; (ii) all conditions, restrictions, and limitations in effect on Restricted Stock Awards pursuant to this Plan shall immediately lapse as of the date of such event; (iii) no other terms, conditions, restrictions or limitations shall be imposed upon any such Awards on or after such date, and in no circumstance shall such Awards be forfeited on or after such date; and (iv) all such Awards shall automatically become one hundred percent (100%) vested immediately.

(b)    Valuation and Payment of Awards. Upon a Change in Control, each Non-Employee Director, whether or not continuing in service as a director of the Company in any capacity, shall be paid, in a single lump-sum cash payment, as soon as practicable but in no event later than seventy-five (75) days after the effective date of the Change in Control, the value of all of his or her outstanding

Restricted Stock Awards. For purposes of calculating the cash-out value of Awards for purposes of this Section 5.4, the Fair Market Value of Shares as of the date of the Change in Control shall be used as the Fair Market Value of the Shares.

5.5.    DEFERRAL OF RESTRICTED STOCK AWARDS.

(a)    An Eligible Participant may elect to defer receipt of the whole shares of Restricted Stock granted to the Eligible Participant during a Deferral Year as an Annual Restricted Stock Award. Such a Stock Deferral Election shall be made by the Eligible Participant by filing with the Committee (or with the Company as the Committee’s agent) a Deferral Election Form on or before the Election Deadline for the Deferral Year. A Stock Deferral Election shall become irrevocable on the first day of the Deferral Year to which it relates.

(b)    The shares of Restricted Stock under an Annual Restricted Stock Award for which a Stock Deferral Election is made under this Section 5.5 and which became vested pursuant to Section 5.3 (“Vested Deferred Shares”) shall be converted as of the Vesting Date to a credit under the Deferred Compensation Plan and shall be credited to an account under that plan. The amount credited to the Deferred Compensation Plan for the Vested Deferred Shares shall be equal to the Fair Market Value of such Vested Deferred Shares, determined as of the Vesting Date. No shares of Stock shall be issued with respect to the Vested Deferred Shares. An Eligible Participant’s rights with respect to amounts credited to the Deferred Compensation Plan with respect to Vested Deferred Shares shall be governed by the terms of the Deferred Compensation Plan.

(c)    An Eligible Participant who does not submit a valid Deferral Election Form to the Committee (or the Company as the Committee’s agent) on or before the Election Deadline for the Deferral Year shall have issued to him or her a certificate or certificates for unrestricted shares of Stock in accordance with the terms of his or her Award Notice and the terms of this Plan and the Omnibus Plan.

6.1.    AMENDMENT, MODIFICATION AND TERMINATION. The Board may, at any time and from time to time, amend, modify, or terminate the Plan without stockholder approval; provided, however, that if an amendment to the Plan would, in the reasonable opinion of the Board, require stockholder approval under applicable laws, policies, or regulations or the applicable listing or other requirements of a securities exchange on which the Stock is listed or traded, then such amendment shall be subject to stockholder approval; and provided further, that the Board may condition any other amendment or modification on the approval of stockholders of the Company for any reason.

7.1.    ADJUSTMENTS. The adjustment provisions of the Omnibus Plan shall apply with respect to Awards outstanding or to be awarded or granted pursuant to this Plan.
