This Agreement is entered into pursuant to, and the terms of the Restricted Stock are subject to, the terms of the Plan. If there is any inconsistency between an express provision of this Agreement and an express provision of the Plan, the provision of the Plan shall govern. If the Employee intends to make the election provided in Section 83(b) of the Code with respect to such Shares, the Employee shall notify the Company at least five (5) business days in advance of the making thereof.

Section 2. Vesting of Restricted Stock.

(a) Vesting Based on Continued Employment. [To be completed in connection with specific grants]. Upon the vesting of any portion of the Restricted Stock, such portion shall cease to be “Restricted Stock” pursuant to this Agreement.

(b) Discretionary Acceleration. The Administrator, in its sole discretion, may accelerate the vesting of all or a portion of the Restricted Stock at any time and from time to time.

(c) Effect of a Change in Control. In the event of a Change in Control, all or a portion of the Shares of Restricted Stock shall be converted into Alternative Awards meeting the requirements of the Plan; provided, that, if so determined by the Administrator prior to the Change in Control, all of or a portion of the Shares of Restricted Stock shall be cancelled as set forth in Article XIV of the Plan for the payment described therein.

Section 3. Effect of a Termination of Employment. If the Employee’s employment with the Company terminates for any reason prior to the vesting thereof, any Shares of Restricted Stock that have not vested before the effective date of such termination of employment or that do not become vested on such date shall be immediately forfeited and cancelled upon such termination of employment.

Section 4. Treatment of Dividends. If the Company pays any cash dividend or similar cash distribution on the Company Common Stock, the Company shall credit to the Employee’s account an amount equal to the product of (x) the number of the Employee’s Restricted Stock as of the record date for such distribution times (y) the per share amount of such dividend or similar cash distribution on Company Common Stock. If the Company makes any dividend or other distribution on the Company Common Stock in the form of Company Common Stock or other securities, the Company will credit the Employee’s account with that number of additional Shares or other securities that would have been distributed with respect to that number of Shares underlying the Employee’s Restricted Stock as of the record date thereof, or, in its discretion, the Administrator may elect to credit the value (as determined by the Administrator) of such additional Shares or other securities to the Employee’s account in cash. Any such additional Shares, other securities or cash shall be subject to the same restrictions as apply to the Restricted Stock and shall be paid to the Employee if and when the related Restricted Stock vests (and shall be forfeited if the related Restricted Stock is forfeited).

Section 6. Miscellaneous.

(a) Withholding. The Company or one of its Subsidiaries may require the Employee to remit to the Company an amount in cash sufficient to satisfy any applicable U.S. federal, state and local and non-U.S. tax withholding obligations that may arise in connection with the vesting of the Restricted Stock. Notwithstanding the preceding sentence, unless previously satisfied on or prior to the vesting date, the Company shall retain a number of Shares subject to the Restricted Stock then vesting that have an aggregate Fair Market Value as of the vesting date equal to the amount of such taxes required to be withheld (and the Employee shall thereupon be deemed to have satisfied his or her obligations under this Section 6(a)); provided that the number of Shares retained shall be effected at a rate determined by the Company that is permitted under applicable

2

IRS withholding rules and that does not to cause adverse accounting consequences (it being understood that the value of any fractional share of Company Common Stock shall be paid in cash). The number of Shares registered in the name of the Employee shall thereupon be reduced by the number of Shares so retained. The method of withholding set forth in the immediately preceding sentence shall not be available if withholding in this manner would violate any financing instrument of the Company or any of its Subsidiaries or to the extent that a facility is available to the Employee by which the Employee may sell Shares in the public market to satisfy such obligations.

(b) Incorporation of Forfeiture Provisions. The Employee acknowledges and agrees that, pursuant to the Plan, he or she shall be subject to any generally applicable disgorgement or forfeiture provisions set forth in Article XIII of the Plan as of the date of this Agreement or as may be imposed by the Administrator (including as required by applicable law) after the date of this Agreement, including with respect to post-employment Competitive Activity. The Employee hereby appoints the Company as the Employee’s attorney-in-fact of the undersigned to take such actions as may be necessary or appropriate to effect a transfer of the record ownership of any such Shares to which such disgorgement or forfeiture provisions may apply.

(c) No Right to Continued Employment. Nothing in this Agreement shall be deemed to confer on the Employee any right to continue in the employ of the Company or any Subsidiary, or to interfere with or limit in any way the right of the Company or any Subsidiary to terminate such employment at any time.

(d) Non-Transferability of Restricted Stock. Prior to the vesting date thereof, the Shares of Restricted Stock are not assignable or transferable, in whole or in part, and they may not, directly or indirectly, be offered, transferred, sold, pledged, assigned, alienated, hypothecated or otherwise disposed of or encumbered (including, but not limited to, by gift, operation of law or otherwise) other than by will or by the laws of descent and distribution to the estate of the Employee upon the Employee’s death or with the Company’s consent.
