Grant of Restricted Stock Units. The Company has granted to the Participant, effective as of the Date of Grant, XXXX Restricted Stock Units, on the terms and conditions set forth in the Plan and this Agreement, subject to adjustment as set forth in the Plan (the “RSUs”).

Vesting of RSUs. Subject to the terms and conditions set forth in the Plan and this Agreement, the RSUs will vest as follows:

General. Except as otherwise provided in Sections 2(b) and 4, 100% of the Shares subject to the RSUs will vest on the first anniversary of the Date of Grant, or, if earlier, the date of the next subsequent annual meeting following the Date of Grant but only to the extent the Participant is not re-elected as a Non-Employee Director at such annual meeting, in each case, subject to the Participant’s continued Service through the applicable vesting date.

Settlement in Stock. RSUs vested as described in Section 2 above will be settled by delivering to Participant a number of Shares equal to the number of vested RSUs on the date on which the RSUs vest, subject to the terms of this Agreement.

Book-­Entry Registration of the Shares; Delivery of Shares. As soon as practical after the applicable vesting date, the Company will, at its election, either: (i) issue a certificate representing the Shares payable pursuant to this Agreement; or (ii) not issue any certificate representing the Shares payable pursuant to this Agreement and instead document the Participant’s interest in the Shares by registering such Shares with the Company’s transfer agent (or another custodian selected by the Company) in book­-entry form in the Participant’s name. In any case, the Company may provide a reasonable delay in the issuance or delivery of the Shares to address any applicable Tax-­Related Items, withholding, and other administrative matters. Neither the Company nor the Committee will be liable to the Participant or any other Person for damages relating to any delays in issuing the Shares or any mistakes or errors in the issuance of the Shares.

Shareholder Rights. The Participant will not have any rights of a stockholder with respect to the Shares subject to the RSUs, including voting and dividend rights, unless and until the Shares are delivered as described in Section 3(b) above.

Withholding Requirements. The Participant acknowledges that the Participant will consult with his or her personal tax advisor regarding the Tax-Related Items that arise in connection with this Agreement. The Participant is relying solely on such advisor and is not relying in any part on any statement or representation of the Company or any of its agents. The Company shall not be responsible for withholding any Tax-Related Items, unless required by applicable law. The Company may take such action as it deems appropriate to ensure that all Tax-Related Items, which are the Participant’s sole and absolute responsibility, are withheld or collected from the Participant, if and to the extent required by applicable law. In this regard, the Company will have the power and the right to require the Participant to remit to the Company, the amount necessary to satisfy federal, state and local taxes, domestic or foreign, required by law or regulation to be withheld with respect to any taxable event arising as a result of this Agreement (collectively, "Withheld Taxes"). Notwithstanding the foregoing, unless otherwise determined by the Committee, any obligations to pay Withheld Taxes will be met by having the Company withhold a number of Shares from the total number of Shares otherwise issuable to Participant pursuant to this Agreement having a Fair Market Value on the date the Withheld Taxes are to be determined equal to the minimum statutory total Withheld Taxes that could be imposed on the transaction as determined by the Company; provided, however, that to the extent permitted by U.S. generally accepted accounting principles, the number of

Forfeiture. Any unvested RSUs will be forfeited immediately, automatically and without consideration upon a termination of the Participant’s Service for any reason.

Securities Laws Requirements or Exchange Control Laws Requirements. No Shares will be issued or transferred pursuant to this Agreement unless and until all then applicable requirements imposed by federal and state securities and other securities or exchange control laws, rules and regulations and by any regulatory agencies having jurisdiction, and by any exchanges upon which the Shares may be listed, have been fully met. As a condition precedent to the issuance of Shares pursuant to this Agreement, the Company may require the Participant to take any reasonable action to meet those requirements. The Committee may impose such conditions on any Shares issuable pursuant to this Agreement as it may deem advisable, including, without limitation, restrictions under the Securities Act of 1933, as amended, under the requirements of any exchange upon which shares of the same class are then listed and under any blue sky or other securities laws applicable to those Shares.

Non­-Transferability. The RSUs and the rights and privileges conferred thereby shall be non-transferrable except as provided by Section 15.3 of the Plan. Any shares of Common Stock delivered hereunder will be subject to such stop transfer orders and other restrictions as the Committee 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 shares are listed, any applicable federal or state laws and any agreement with, or policy of, the Company or the Committee to which the Participant is a party or subject, and the Committee may cause orders or designations to be placed upon any certificate(s) or other document(s) delivered to the Participant, or on the books and records of the Company’s transfer agent, to make appropriate reference to such restrictions.

No Right to Continued Service. Nothing in this Agreement or the Plan confers upon the Participant any right to continue in Service for any period of specific duration.

Notification.
