GENERAL

1.1          Issuance of Shares.  The Company will issue the Shares to the Participant effective as of the grant date set forth in the Grant Notice and will cause (a) a stock certificate or certificates representing the Shares to be registered in Participant’s name or (b) the Shares to be held in book-entry form.

TAXATION AND TAX WITHHOLDING

2.1          Representation.  Participant represents to the Company that Participant has reviewed with Participant’s own tax advisors the tax consequences of the Shares and the transactions contemplated by the Grant Notice and this Agreement.  Participant is relying solely on such advisors and not on any statements or representations of the Company or any of its agents.

2.2          Tax Withholding.

(a)           The Company has the right and option, but not the obligation, to treat Participant’s failure to provide timely payment in accordance with the Plan of any withholding tax arising in connection with the Shares as Participant’s election to satisfy all or any portion of the withholding tax by requesting the Company retain Shares otherwise deliverable under the Award.

(b)           Participant acknowledges that Participant is ultimately liable and responsible for all taxes owed in connection with the Shares, regardless of any action the Company or any Subsidiary takes with respect to any tax withholding obligations that arise in connection with the Shares.  Neither the Company nor any Subsidiary makes any representation or undertaking regarding the treatment of any tax withholding in connection with the awarding or payment of the Shares or the subsequent sale of the Shares.  The Company and the Subsidiaries do not commit and are under no obligation to structure this Award to reduce or eliminate Participant’s tax liability.

3.10        Limitation on Participant’s Rights.  Participation in the Plan confers no rights or interests other than as herein provided.  This Agreement creates only a contractual obligation on the part of the Company as to amounts payable and may not be construed as creating a trust.  Neither the Plan nor any underlying program, in and of itself, has any assets.  Participant will have only the rights of a general unsecured creditor of the Company with respect to amounts credited and benefits payable, if any, with respect to the Award.

3.11        Not a Contract of Employment.  Nothing in the Plan, the Grant Notice or this Agreement confers upon Participant any right to continue in the employ or service of the Company or any Subsidiary or interferes with or restricts in any way the rights of the Company and its Subsidiaries, which rights are hereby expressly reserved, to discharge or terminate the services of Participant at any time for any reason
