(e) Acceleration of Vesting at Company Discretion. Notwithstanding any other term or provision of this Agreement, the Board or the Committee shall be authorized, in its sole discretion, based upon its review and evaluation of the performance of the Recipient and of the Company, to accelerate the vesting of any shares of Restricted Stock under this Agreement, at such times and upon such terms and conditions as the Board or the Committee shall deem advisable.

3. Delivery of Restricted Stock.

(a) Issuance of Stock Certificates and Legends. One or more stock certificates evidencing the Restricted Stock shall be issued in the name of the Recipient but shall be held and retained by the Records Administrator of the Company until the date (the “Applicable Date”) on which the shares (or a portion thereof) subject to this Restricted Stock award become Vested Shares pursuant to Section 2 hereof, subject to the provisions of Section 4 hereof. All such stock certificates shall bear the following legends, along with such other legends that the Board or the Committee shall deem necessary and appropriate or which are otherwise required or indicated pursuant to any applicable stockholders agreement:

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO SUBSTANTIAL VESTING AND OTHER RESTRICTIONS AS SET FORTH IN THE RESTRICTED STOCK AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH

2

RESTRICTIONS ARE BINDING ON TRANSFEREES OF THESE SHARES, AND INCLUDE VESTING CONDITIONS WHICH MAY RESULT IN THE COMPLETE FORFEITURE OF THE SHARES.

(b) Stock Powers. The Recipient shall deposit with the Company stock powers or other instruments of transfer or assignment, duly endorsed in blank with signature(s) guaranteed, corresponding to each certificate representing shares of Restricted Stock until such shares become Vested Shares. If the Recipient shall fail to provide the Company with any such stock power or other instrument of transfer or assignment, the Recipient hereby irrevocably appoints the Secretary of the Company as his attorney-in-fact, with full power of appointment and substitution, to execute and deliver any such power or other instrument which may be necessary to effectuate the transfer of the Restricted Stock (or assignment of distributions thereon) on the books and records of the Company.

(c) Delivery of Stock Certificates. On or after each Applicable Date, upon written request to the Company by the Recipient, the Company shall promptly cause a new certificate or certificates to be issued for and with respect to all shares that become Vested Shares on that Applicable Date, which certificate(s) shall be delivered to the Recipient as soon as administratively practicable after the date of receipt by the Company of the Recipient’s written request. The new certificate or certificates shall continue to bear those legends and endorsements that the Company shall deem necessary or appropriate (including those relating to restrictions on transferability and/or obligations and restrictions under the Securities Laws).

(d) Issuance Without Certificates. If the Company is authorized to issue Shares without certificates, then the Company may, in the discretion of the Committee, issue Shares pursuant to this Agreement without certificates, in which case any references in this Agreement to certificates shall instead refer to whatever evidence may be issued to reflect the Recipient’s ownership of the Shares subject to the terms and conditions of this Agreement.

4. Forfeiture of Non-Vested Shares. If the Recipient’s Continuous Service with the Company and the Related Entities is terminated for any reason, any Shares of Restricted Stock that are not Vested Shares, and that do not become Vested Shares pursuant to Section 2 hereof as a result of such termination, shall be forfeited immediately upon such termination of Continuous Service and revert back to the Company without any payment to the Recipient. [If the Recipient’s Continuous Service is terminated by the Company or a Related Entity for Cause, all Vested and Non-Vested Shares shall be forfeited immediately upon such termination of Continuous Service and revert back to the Company without any payment to the Recipient.] The Committee shall have the power and authority to enforce on behalf of the Company any rights of the Company under this Agreement in the event of the Recipient’s forfeiture of [Vested or] Non-Vested Shares pursuant to this Section 4.

5. Rights with Respect to Restricted Stock.

(a) General. Except as otherwise provided in this Agreement, the Recipient shall have, with respect to all of the shares of Restricted Stock, whether Vested Shares or Non-Vested Shares, all of the rights of a holder of shares of common stock of the Company, including

3

without limitation (i) the right to vote such Restricted Stock, (ii) the right to receive dividends, if any, as may be declared on the Restricted Stock from time to time, and (iii) the rights available to all holders of shares of common stock of the Company upon any merger, consolidation, reorganization, liquidation or dissolution, stock split-up, stock dividend or recapitalization undertaken by the Company; provided, however, that all of such rights shall be subject to the terms, provisions, conditions and restrictions set forth in this Agreement (including without limitation conditions under which all such rights shall be forfeited). Any Shares issued to the Recipient as a dividend with respect to shares of Restricted Stock shall have the same status and bear the same legend as the shares of Restricted Stock and shall be held by the Company, if the shares of Restricted Stock that such dividend is attributed to is being so held, unless otherwise determined by the Committee. In addition, notwithstanding any provision to the contrary herein, any cash dividends declared with respect to shares of Restricted Stock subject to this Agreement shall be held in escrow by the Committee until such time as the shares of Restricted Stock that such cash dividends are attributed to shall become Vested Shares, and in the event that such shares of Restricted Stock are subsequently forfeited, the cash dividends attributable to such portion shall be forfeited as well.

(b) Adjustments to Shares. If at any time while this Agreement is in effect (or Shares granted hereunder shall be or remain unvested while Recipient’s Continuous Service continues and has not yet terminated or ceased for any reason), there shall be any increase or decrease in the number of issued and outstanding Shares of the Company through the declaration of a stock dividend or through any recapitalization resulting in a stock split-up, combination or exchange of such Shares, then and in that event, the Board or the Committee shall make any adjustments it deems fair and appropriate, in view of such change, in the number of shares of Restricted Stock then subject to this Agreement. If any such adjustment shall result in a fractional Share, such fraction shall be disregarded.

(c) No Restrictions on Certain Transactions. Notwithstanding any term or provision of this Agreement to the contrary, the existence of this Agreement, or of any outstanding Restricted Stock awarded hereunder, shall not affect in any manner the right, power or authority of the Company to make, authorize or consummate: (i) any or all adjustments, recapitalizations, reorganizations or other changes in the Company’s capital structure or its business; (ii) any merger, consolidation or similar transaction by or of the Company; (iii) any offer, issue or sale by the Company of any capital stock of the Company, including any equity or debt securities, or preferred or preference stock that would rank prior to or on parity with the Restricted Stock and/or that would include, have or possess other rights, benefits and/or preferences superior to those that the Restricted Stock includes, has or possesses, or any warrants, options or rights with respect to any of the foregoing; (iv) the dissolution or liquidation of the Company; (v) any sale, transfer or assignment of all or any part of the stock, assets or business of the Company; or (vi) any other corporate transaction, act or proceeding (whether of a similar character or otherwise).

The terms of this Agreement shall be binding upon the executors, administrators, heirs, successors

and assigns of the Recipient. Except as otherwise permitted pursuant to the first sentence of this Section, any attempt to effect a Transfer of any shares of Restricted Stock prior to the date on which the shares become Vested Shares shall be void ab initio. For purposes of this Agreement, “Transfer” shall mean any sale, transfer, encumbrance, gift, donation, assignment, pledge, hypothecation, or other disposition, whether similar or dissimilar to those previously enumerated, whether voluntary or involuntary, and including, but not limited to, any disposition by operation of law, by court order, by judicial process, or by foreclosure, levy or attachment.

If the Recipient shall fail to make such tax payments as are required, the Company shall, to the extent permitted by law, have the right to deduct from any payment of any kind (including without limitation, the withholding of any Shares that otherwise would be issued to the Recipient under this Agreement) otherwise due to the Recipient any federal, state or local taxes of any kind required by law to be withheld with respect to the Restricted Stock.

(c) Satisfaction of Withholding Requirements. The Recipient may satisfy the withholding requirements with respect to the Restricted Stock pursuant to any one or combination of the following methods:

(i) payment in cash; or

(ii) if and to the extent permitted by the Committee, payment by surrendering unrestricted previously held Shares which have a value equal to the required withholding amount or the withholding of Shares that otherwise would be deliverable to the Recipient pursuant to this Award. The Recipient may surrender Shares either by attestation or by delivery of a certificate or certificates for shares duly endorsed for transfer to the Company, and if required with medallion level signature guarantee by a member firm of a national stock exchange, by a national or state bank (or guaranteed or notarized in such other manner as the Committee may require).

The Recipient shall consult with his or her own personal accountant(s) and/or tax advisor(s) regarding these matters, the making of a Section 83(b) election, and the Recipient’s filing, withholding and payment (or tax liability) obligations.

(i) Section 409A.

(a) It is intended that the Restricted Stock awarded pursuant to this Agreement be exempt from Section 409A of the Code (“Section 409A”) because it is believed that the Agreement does not provide for a deferral of compensation and accordingly that the Agreement does not constitute a nonqualified deferred compensation plan within the meaning of Section 409A. The provisions of this Agreement shall be interpreted in a manner consistent with this intention, and the provisions of this Agreement may not be amended, adjusted, assumed or substituted for, converted or otherwise modified without the Recipient’s prior written consent if and to the extent that the Company believes or reasonably should believe that such amendment, adjustment, assumption or substitution, conversion or modification would cause the award to violate the requirements of Section 409A.

(b) In the event that either the Company or the Recipient believes, at any time, that any benefit or right under this Agreement is subject to Section 409A, and does not comply with the requirements of Section 409A, it shall promptly advise the other and the Company and

7

the Recipient shall negotiate reasonably and in good faith to amend the terms of such benefits and rights, if such an amendment may be made in a commercially reasonable manner, such that they comply with Section 409A with the most limited possible economic affect on the Recipient and on the Company.

(c) Notwithstanding the foregoing, the Company does not make any representation to the Recipient that the shares of Restricted Stock awarded pursuant to this Agreement are exempt from, or satisfies, the requirements of Section 409A, and the Company shall have no liability or other obligation to indemnify or hold harmless the Recipient or any Beneficiary for any tax, additional tax, interest or penalties that the Recipient or any Beneficiary may incur in the event that any provision of this Agreement, or any amendment or modification thereof or any other action taken with respect thereto that either is consented to by the Recipient or that the Company reasonably believes should not result in a violation of Section 409A, is deemed to violate any of the requirements of Section 409A.

(j) Non-Waiver of Breach. The waiver by any party hereto of the other party’s prompt and complete performance, or breach or violation, of any term or provision of this Agreement shall be effected solely in a writing signed by such party, and shall not operate nor be construed as a waiver of any subsequent breach or violation, and the waiver by any party hereto to exercise any right or remedy which he or it may possess shall not operate nor be construed as the waiver of such right or remedy by such party, or as a bar to the exercise of such right or remedy by such party, upon the occurrence of any subsequent breach or violation.

(k) Counterparts. This Agreement may be executed in two or more separate counterparts, each of which shall be an original, and all of which together shall constitute one and the same agreement.

IN WITNESS WHEREOF, the parties hereto, intending to be legally bound, have executed this Agreement as of the date first written above.
