2.1 Subject to Sections 2.3, 2.5, and 2.6 below, if the Grantee remains employed by the Company, the Restricted Stock shall vest in equal annual installments over three (3) years, as follows (each such date on which the Restricted Stock vests is hereinafter referred to as a “Vesting Date”):

2.2 Except as otherwise provided below, on each Vesting Date, Grantee shall own the Vested Shares of Restricted Stock free and clear of all restrictions imposed by this Agreement (except those imposed by Section 3.4 below). The Company shall transfer the Vested Shares of Restricted Stock to an unrestricted account in the name of the Grantee as soon as practical after each Vesting Date.

2.3 In the event, prior to the Vesting Date, (i) Grantee dies while actively employed by the Company, or (ii) Grantee has his employment terminated by reason of Disability, any Restricted Stock shall become fully vested and nonforfeitable as of the date of Grantee’s death or Disability. The Company shall transfer the Shares of Restricted Stock, free and clear of any restrictions imposed by this Agreement (except for Section 3.4) to Grantee (or, in the event of death, to his surviving spouse or, if none, to his estate) as soon as practical after his date of death or termination for Disability.

2.4 In exchange for receipt of consideration in the form of the Restricted Stock award pursuant to this Agreement, the prospect of receiving such awards in the future, continued employment, and other good and valuable consideration, Grantee agrees that, in the event his employment with the Company is terminated, for the period set forth in the Exhibits attached hereto (the “Restricted Period”), Grantee shall comply with the non-competition, non-solicitation, non-recruitment, and non-disclosure restrictions attached hereto as Exhibits “A,” “B,” and “C,” respectively (the “Restrictive Covenants”). The parties hereto recognize that Grantee may experience periodic material changes in his job title and/or to the principal duties, responsibilities or services that he is called upon to perform on the behalf of the Company. If Grantee experiences such a material job change, the parties shall, as soon as is practicable, enter into a signed, written addendum to Exhibit “A” hereto reflecting such material change. Moreover, in the event of any material change in corporate organization on the part of the Direct Competitors set forth in Exhibit A hereto, the parties agree to amend Exhibit “A”, as necessary, at the Company’s request, in order to reflect such change. Upon execution, any such written modification to Exhibit “A” shall represent an enforceable amendment to this Agreement and shall augment and supplant the definitions of the terms Executive Services or Direct Competitor set forth in Exhibit “A” hereto, as applicable.

2.5 Except for death or Disability as provided in Section 2.3 or as provided in Section 2.6, or except as otherwise provided in a severance agreement or change in control agreement with Grantee, if Grantee terminates his employment or if the Company terminates Grantee prior to the Vesting Date, the Restricted Stock shall cease to vest further, the unvested Shares of Restricted Stock shall be immediately forfeited, and Grantee shall only be entitled to the Restricted Stock that has vested as of his date of termination.

2.6 Notwithstanding the other provisions of this Agreement, (a) in the event of a Change in Control of the Company (for purposes of this Agreement, a Change in Control shall not include a “Noncovered Transaction”, as defined in Grantee’s Amended and Restated Change

2.7 The Restricted Stock may not be sold, assigned, transferred, pledged, or otherwise encumbered prior to the date Grantee becomes vested in the Restricted Stock.

3.1 The Restricted Stock shall be registered in the name of Grantee as of the respective Grant Date for such Shares of Restricted Stock. The Company may issue stock certificates or evidence Grantee’s interest by using a restricted book entry account with the Company’s transfer agent. Physical possession or custody of any stock certificates that are issued shall be retained by the Company until such time as the Shares are vested in accordance with Section 2. The Company reserves the right to place a legend on such stock certificate(s) restricting the transferability of such certificates and referring to the terms and conditions (including forfeiture) of this Agreement and the Plan.

3.2 During the period the Restricted Stock is not vested, the Grantee shall be entitled to receive dividends or similar distributions declared on such Restricted Stock and Grantee shall be entitled to vote such Restricted Stock.

3.3 In the event of a Change in Capitalization, the number and class of Shares or other securities that Grantee shall be entitled to, and shall hold, pursuant to this Agreement shall be appropriately adjusted or changed to reflect the Change in Capitalization, provided that any such additional Shares or additional or different shares or securities shall remain subject to the restrictions in this Agreement.

3.4 Grantee represents and warrants that he is acquiring the Restricted Stock for investment purposes only, and not with a view to distribution thereof. Grantee is aware that the Restricted Stock may not be registered under the federal or any state securities laws and that in that event, in addition to the other restrictions on the Shares, they will not be able to be transferred unless an exemption from registration is available or the Shares are registered. By making this award of Restricted Stock, the Company is not undertaking any obligation to register the Restricted Stock under any federal or state securities laws.

Nothing in this Agreement or the Plan shall be interpreted or construed to confer upon Grantee any right with respect to continuance of employment by the Company or a subsidiary, nor shall this Agreement or the Plan interfere in any way with the right of the Company or a Subsidiary to terminate Grantee’s employment at any time. The Plan may be terminated at any time, and even if the Plan is not terminated, Grantee shall not be entitled to any additional awards under the Plan.

The Company and Grantee agree to report the value of the Restricted Stock in a consistent manner for federal income tax purposes. The Company shall have the right to retain and withhold from any payment of Restricted Stock or cash the amount of taxes required by any government to be withheld or otherwise deducted and paid with respect to such payment. At its discretion, the Company may require Grantee to reimburse the Company for any such taxes required to be withheld and may withhold any distribution in whole or in part until the Company is so reimbursed. In lieu thereof, the Company shall have the right to withhold from any other cash amounts due to Grantee an amount equal to such taxes required to be withheld or withhold and cancel (in whole or in part) a number of shares of Restricted Stock having a market value not less than the amount of such taxes.

Grantee hereby acknowledges receipt of a copy of the Plan and the prospectus for the Plan, and agrees to be bound by all the terms and provisions thereof.

This Agreement may be modified, amended, suspended, or terminated, and any terms or conditions may be waived, but only by mutual agreement of the parties in writing.

Should any provision of this Agreement be held by a court of competent jurisdiction to be unenforceable or invalid for any reason, the remaining provisions of this Agreement shall not be affected by such holding and shall continue in full force in accordance with their terms.
