The Committee shall select one of its members to act as its Chairman. A majority of the Committee shall constitute a quorum, and the act of a majority of the members of the Committee present at a meeting at which a quorum is present shall be the act of the Committee.

The Committee shall determine and designate from time to time the eligible persons to whom Awards will be granted and shall set forth in each related Award Agreement, the Date of Grant and such other terms, provisions, limitations, and performance requirements (if any), as are approved by the Committee, but not inconsistent with the Plan.

The Committee, in its discretion, shall (i) interpret the Plan, (ii) prescribe, amend, and rescind any rules and regulations necessary or appropriate for the administration of the Plan, and (iii) make such other determinations and take such other action as it deems necessary or advisable in the administration of the Plan.

ELIGIBILITY

Employees who are eligible to participate in the Plan (including an Employee who is also a director or an officer) are those Employees whom the Committee determines are key Employees.

Except as required by this Plan, all Awards shall not be required to contain the same or similar provisions. The Committee’s determinations under the Plan (including without limitation determinations of which Employees or potential Employees, if any, are to receive Awards, the form, amount and timing of such Awards, the terms and provisions of such Awards and the agreements evidencing same) need not be uniform and may be made by it selectively among Employees who receive, or are eligible to receive, Awards under the Plan.

ARTICLE 6

GRANT OF AWARDS

6.1    In General. The grant of an Award shall be authorized by the Committee and shall be evidenced by an Award Agreement setting forth the particular Award being granted, the total number of shares of Restricted Stock or Restricted Stock Units subject to the Award, the Date of Grant, and such other terms, provisions, limitations, and performance objectives (if any), as are approved by the Committee, but not inconsistent with the Plan. The Company shall execute an Award Agreement with a Participant after the Committee approves the issuance of an Award. Any Award granted pursuant to this Plan must be granted within ten (10) years of the date of adoption of this Plan (i.e., December 13, 2000). The grant of an Award to a Participant shall not be deemed either to entitle the Participant to, or to disqualify the Participant from, receipt of any other Award under the Plan.

If the Committee establishes a purchase price for an Award, the Participant must accept such Award within a period of 30 days (or such shorter period as the Committee may specify) after the Date of Grant by executing the applicable Award Agreement and paying such purchase price.

6.2    Maximum Individual Grants. No Participant may receive, during any fiscal year of the Company, Awards covering an aggregate of more than Fifty Thousand (50,000) shares of Common Stock. In addition, in no event shall the total Fair Market Value of any Restricted Stock Unit Awards granted to any Participant during any fiscal year of the Company exceed $1,000,000.

6.3    Award Agreement. The Committee shall set forth in the related Award Agreement: (i) the number of shares of Restricted Stock or number of Restricted Stock Units awarded, (ii) the price, if any, to be paid by the Participant for such Restricted Stock or Restricted Stock Units, (iii) the time or times within which such Award may be subject to forfeiture, (iv) specified performance goals (if applicable) of the Company, any Subsidiary, any division thereof or any group of Employees of the Company, or any other criteria, which the Committee determines must be met in order to remove any restrictions on (including vesting of) such Award, and (v) all other terms, limitations, restrictions, and conditions of the Restricted Stock and the Restricted Stock Units, which shall be consistent with this Plan. The provisions of any one particular Award need not be the same with respect to each Participant.

Each Participant who receives a grant of Restricted Stock Units shall be eligible to receive, at the expiration of the applicable Restriction Period, one share of Common Stock for each Restricted Stock Unit awarded, and the Company shall issue to each such Participant that number of shares of Common Stock, or the cash equivalent of such number of shares (determined by reference to the Fair Market Value of such shares as of the date the Restriction Period expires), or a combination of both.

The Committee may permit Participants to defer receipt of any Common Stock issuable upon the lapse of any restriction of Restricted Stock or Restricted Stock Units, subject to such rules and procedures as it may establish.

6.4    Custody of Shares; Legend on Shares. Each Participant who is awarded Restricted Stock shall be issued a stock certificate or certificates in respect of such shares of Common Stock.

5

Such certificate(s) shall be registered in the name of the Participant, and shall bear an appropriate legend referring to the terms, conditions, and restrictions applicable to such Restricted Stock, substantially as provided in Section 13.8 of the Plan. The Committee may require that the stock certificates evidencing shares of Restricted Stock be held in custody by the Company until the restrictions thereon shall have lapsed, and that the Participant deliver to the Committee a stock power or stock powers, endorsed in blank, relating to the shares of Restricted Stock.

6.5    Restrictions and Conditions. Shares of Restricted Stock (and where applicable, Restricted Stock Units) shall be subject to the following restrictions and conditions:

(a)    No Disposition During Restriction Period. Subject to the other provisions of this Plan and the terms of the particular Award Agreements, during such period as may be determined by the Committee commencing on the Date of Grant (the “Restriction Period”), the Participant shall not be permitted to sell, transfer, pledge, assign, or otherwise dispose of shares of Restricted Stock or any Restricted Stock Units. The Restriction Period for shares of Restricted Stock and Restricted Stock Units shall commence on the Date of Grant of such Award and, subject to Article 10 of the Plan, shall expire upon satisfaction of the conditions set forth in the Award Agreement; such conditions may provide for vesting based on (i) length of continuous service, (ii) achievement of specific business objectives, (iii) increases in specified indices, (iv) attainment of specified growth rates, or (v) other comparable measurements of Company performance (or that of any Subsidiary or division thereof), as may be determined by the Committee in its sole discretion.

(b)    Rights During Restriction Period. Except as provided in paragraph (a) above or hereinbelow, the Participant shall have, with respect to his or her Restricted Stock, all of the rights of a stockholder of the Company. The Participant shall not be entitled to receive any dividends with respect to nonvested shares of Restricted Stock during the Restriction Period and no dividends shall accrue with respect thereto. The Participant shall be entitled to vote the shares of Restricted Stock during the Restriction Period to the same extent as would have been applicable to the Participant if the Participant was then vested in the shares; provided, however, that the Participant shall not be entitled to vote the shares with respect to record dates occurring prior to the Date of Grant, or with respect to record dates occurring on or after the date, if any, on which the Participant has forfeited the Restricted Stock. A Participant who receives Restricted Stock Units shall have no rights as a stockholder with respect to such Restricted Stock Units (including rights to dividends) until such time as any share certificates for Common Stock are issued to the Participant.

(c)    Lapse of Restrictions. Certificates for shares of Common Stock (or their cash equivalent, or a combination of both) free of restriction under this Plan shall be delivered to the Participant promptly after, and only after, the particular Restriction Period shall expire as a result of satisfaction of the conditions set forth in the Award Agreement.

(d)    Forfeiture. Subject to the provisions of the particular Award Agreement, upon Termination of Service for any reason other than the Participant’s death, Total and Permanent Disability, or Retirement during the Restriction Period, the nonvested shares of Restricted Stock and nonvested Restricted Stock Units shall be forfeited by the Participant. In addition, an Award Agreement may provide for forfeiture of shares of Restricted Stock or Restricted Stock Units upon the occurrence of other events, including failure to achieve certain goals or objectives during a

6

specified period of time. In the event a Participant has paid any consideration to the Company for such forfeited Restricted Stock or Restricted Stock Units, the Company shall, as soon as practicable after the event causing forfeiture (but in any event within five (5) business days), pay to the Participant, in cash, an amount equal to the total consideration paid by the Participant for such forfeited shares of Restricted Stock or forfeited Restricted Stock Units. Upon any such forfeiture, all rights of a Participant with respect to the forfeited shares of the Restricted Stock or the forfeited Restricted Stock Units shall cease and terminate, without any further obligation on the part of the Company. Certificates for shares of Common Stock forfeited under the provisions of the Plan and the applicable Award Agreement shall be promptly returned to the Company by the forfeiting Participant. Each Award Agreement shall require that (i) each Participant, by his or her acceptance of Restricted Stock or Restricted Stock Units, irrevocably grants to the Company a power of attorney to transfer to the Company any shares or Units so forfeited, and agrees to execute any documents or instruments (including stock powers) requested by the Company in connection with such forfeiture and transfer, and (ii) such provisions regarding returns and transfers of Units or stock certificates with respect to forfeited shares of Common Stock shall be specifically performable by the Company in a court of equity or law.

ARTICLE 7

AMENDMENT OR DISCONTINUANCE

Subject to the limitations set forth in this Article 7, the Board may at any time and from time to time, without the consent of the Participants, alter, amend, revise, suspend, or discontinue the Plan in whole or in part.

ARTICLE 8

7

(i) An appropriate adjustment shall be made in the maximum number of shares of Common Stock then subject to being awarded under the Plan and in the maximum number of shares of Common Stock that may be awarded to a Participant to the end that the same proportion of the Company’s issued and outstanding shares of Common Stock shall continue to be subject to being so awarded; and

(ii) Appropriate adjustments shall be made in the number of outstanding shares of Restricted Stock and Restricted Stock Units with respect to which the applicable Restriction Period has not expired prior to any such change.

Except as otherwise expressly provided herein, the issuance by the Company of shares of its capital stock of any class, or securities convertible into shares of capital stock of any class, either in connection with direct sale or upon the exercise of rights, options, or warrants to subscribe therefor, or upon conversion of shares or obligations of the Company convertible into such shares or other securities, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number of outstanding shares of Restricted Stock or the number of outstanding Units.

Upon the occurrence of each event requiring an adjustment with respect to any Award, the Company shall mail to each affected Participant its computation of such adjustment which shall be conclusive and shall be binding upon each such Participant.
