2. Vesting of Restricted Stock.

(a) Vesting Schedule. The Award shall initially be unvested. Provided that the Participant has not undergone a Termination and a Manager Termination Event has not occurred, if the Participant is a Manager Employee, the Award shall vest (i) with respect to one-sixth (1/6) of the Award on the date that is six months and one day following the Date of Grant (the “Initial Vesting Date”) and (ii) with respect to the rest of the Award, in substantially equal quarterly installments over the ten (10) quarters immediately following the Initial Vesting Date; provided that the exact amounts and dates of each installment vesting shall be determined by the Company.

(b) Termination. Upon any Manager Termination Event, Qualifying Manager Termination or if the Participant undergoes a Termination, this Award shall be treated in accordance with the Plan.

3. Book Entry; Certificates. The Company shall recognize the Participant’s ownership through uncertificated book entry. If elected by the Company, certificates evidencing the Common Stock granted hereunder may be issued by the Company and any such certificates shall be registered in the Participant’s name on the stock transfer books of the Company promptly after the date hereof, but shall remain in the physical custody of the Company or its designee at all

times prior to the later of (x) the vesting of the Award pursuant to this Agreement and (y) the expiration of any transfer restrictions set forth in this Agreement or otherwise applicable to the Common Stock subject to the Award. As soon as practicable following such time, any certificates for the Common Stock subject to the Award shall be issued to the Participant or to the Participant’s legal guardian or representative along with the stock powers relating thereto. No certificates shall be issued for fractional shares. To the extent required by the Company, the Participant shall deliver to the Company a stock power, duly endorsed in blank, relating to any portion of the Award that has not previously vested. However, the Company shall not be liable to the Participant for damages relating to any delays in issuing the certificates (if any) to the Participant, any loss by the Participant of the certificates, or any mistakes or errors in the issuance of the certificates or in the certificates themselves.

4. Rights as a Stockholder. The Participant shall be the record owner of the shares of Restricted Stock until or unless such shares are forfeited pursuant to the terms of this Agreement, and as record owner shall be entitled to all rights of a common stockholder of the Company, including, without limitation, participating in gains and losses of the Company, voting rights and rights to dividends with respect to shares of Restricted Stock; provided that shares of Restricted Stock shall be subject to the limitations on transfer and encumbrance set forth in Section 7.

5. Restrictions. Any Common Stock issued to the Participant pursuant to the Award shall be subject to such stop transfer orders and other restrictions as the Committee (or its designee) may deem advisable under the Plan or the rules, regulations, and other requirements of the Securities and Exchange Commission, any stock exchange upon which such Common Stock are listed and any applicable U.S. or non-U.S. federal, state or local laws, and the Committee (or its designee) may cause a notation or notations to be entered into the books and records of the Company to make appropriate reference to such restrictions.

6. No Right to Continued Employment or Service. Neither the Plan nor this Agreement nor the granting of the Award hereunder shall impose any obligation on the Company or any Affiliate of the Company to continue the employment or engagement of the Participant. Further, the Company or any Affiliate of the Company (as applicable) may at any time terminate the Participant, free from any liability or claim under the Plan or this Agreement, except as otherwise expressly provided herein.

7. Transferability.

(a) Shares of Restricted Stock may not, at any time prior to becoming vested pursuant to the terms of this Agreement, be Transferred and any such purported Transfer shall be void and unenforceable against the Company or any Affiliate of the Company; provided that the designation of a beneficiary shall not constitute an assignment, alienation, pledge, attachment, sale, transfer or encumbrance.

(b) “Transfer” shall mean (in either the noun or the verb form, including with respect to the verb form, all conjugations thereof within their correlative meanings) with respect to any security, the gift, sale, assignment, transfer, pledge, hypothecation or other disposition (whether for or without consideration, whether directly or indirectly, and whether voluntary, involuntary or by operation of law) of such security or any interest therein.
