REGISTRATION. The shares of Stock that may be issued under the Plan are registered with the Securities and Exchange Commission under a Registration Statement on Form S-8.

SALE OF SECURITIES. The shares of Stock that may be issued under this Agreement may not be sold or otherwise disposed of in any manner that would constitute a violation of any applicable federal or state securities laws. You also agree that (a) the Company may refuse to cause the transfer of the shares to be registered on the stock register of the Company if such proposed transfer would in the opinion of counsel satisfactory to the Company constitute a violation of any applicable federal or state securities law and (b) the Company may give related instructions to the transfer agent, if any, to stop registration of the transfer of the shares.

REIMBURSEMENT OF EXECUTIVE COMPENSATION IN RESTATEMENT SITUATIONS: To the extent permitted by law, and as determined by the Board in its judgment, the Company may require reimbursement of a portion of any payment to you under this Agreement when (a) the award payment was predicated upon the achievement of certain financial results that were subsequently the subject of a material restatement; and (b) a lower payment would have been made to you based upon the restated financial results. In each such instance, the Company will, to the extent practicable, seek to recover the amount by which your payment for the relevant period exceeded the lower payment that would have been made based on the restated financial results. No reimbursement shall be required if such material restatement was caused by or resulted from any change in accounting policy or rules.

AGREEMENT TO REPAYMENT OF PERFORMANCE BASED INCENTIVE COMPENSATION WHEN PAYMENTS ARE REQUIRED UNDER FEDERAL LAW OR THE RULES OF AN EXCHANGE: Grantee acknowledges that the Company is a publicly-traded entity subject to the laws and regulations of the United States Securities and Exchange Commission, as well as the requirements of the New York Stock Exchange. The Grantee further acknowledges that the Company’s approved form agreements for performance-based incentive compensation granted to Grantee contain certain “clawback” terms and provisions. Grantee agrees to the terms and conditions of any policy adopted by the Company to comply with, or any decision of the Company to adhere to, any requirement or policy of the New York Stock Exchange (or any other exchange on which the securities of the Company are listed) pursuant to Section 10D of the Securities Exchange Act of 1934 (the “Policy”) from this point forward for any grants made previously or in the future. Section 10D provides for the recovery of incentive-based compensation that has been erroneously granted, earned, vested or paid because of one or more errors that are material in the financial statements of the Company. To the extent such Policy requires the repayment or recovery of incentive-based compensation granted to, or earned or received by Grantee, or in which the Grantee vested, whether granted, vested, earned or paid pursuant to any past or future award agreements or any other plan of incentive-based compensation maintained in the past or adopted in the future by the Company, Grantee agrees to the forfeiture, recovery or repayment of such amounts to the extent required by such Policy.

EMPLOYER LIABLE FOR PAYMENT. Except as the Committee may determine otherwise in connection with a Change in Control, the Employer is liable for the payment of any amounts that become due under this Agreement.

SECTION 409A OF THE INTERNAL REVENUE CODE. This Agreement and all payments made hereunder, are intended to meet the short-term deferral exception described under section 1.409A-1(b)(4) of the applicable Treasury regulations, or otherwise comply with, Section 409A, and this Agreement shall be interpreted so as to effect that intent. By accepting this award, you acknowledge and agree that (a) you are not relying upon any written or oral statement or oral statement or representation of the Company, its Affiliates, or any of their respective employees, directors, officers, attorneys or agents (collectively, the “Company Parties”) regarding the tax effects associated with execution of this Agreement and the payment made pursuant to the Plan, and (b) in deciding to enter into this Agreement, you are relying on your own judgment and the judgment of the professionals of your choice with whom you have consulted. By accepting this award, you thereby release, acquit and forever discharge the Company Parties from all actions, causes of actions, suits, debts, obligations, liabilities, claims, damages, losses, costs and expenses of any nature whatsoever, known or unknown, on account of, arising out of, or in any way related to the tax effects associated with the award and this Agreement.

PAYMENT TO RABBI TRUST IN CONNECTION WITH DELAYED PAYMENT. If the Company determines in its sole discretion that you are a Specified Employee as of any Payment Date and that Section 409A applies as set forth in this Agreement, then any such portion payable during the Six-Month Delay Period shall be transferred to a rabbi trust (which shall be a rabbi trust previously created by the Company that contains other amounts of deferred compensation payable by the Company or a rabbi trust created by the Company or its successor) as soon as administratively feasible following the occurrence of the event giving rise to your right to such payment, except to the extent such transfer would subject you to penalties under the funding restriction provisions of Section 409A, as amended by the Pension Protection Act of 2006, and such amounts (together with earnings thereon determined in accordance with the terms of the trust agreement) shall be transferred from the trust to you upon the earlier of (i) the expiration of the Six-Month Delay Period, or (ii) any other earlier date permitted under Section 409A.

TAX-BASED PROGRAM CRITERIA. The Plan is designed to conform to the requirements of Section 162(m) of the Internal Revenue Code, which limits the amount the Company can deduct for non-performance-based compensation. Performance-based compensation meeting the requirements of the Internal Revenue Code is not subject to this limit. The award granted hereby is intended to meet these requirements so that the Company can deduct this element of compensation.

FRACTIONAL SHARES PAID IN CASH. In the event any share of Stock due hereunder is a fractional share, the Company shall pay the value of such fractional share in cash.

MISCELLANEOUS. This Agreement is awarded pursuant to and is subject to all of the provisions of the Plan, including amendments to the Plan, if any. In the event of a conflict between this Agreement and the Plan provisions, the Plan provisions will control. The term “you” and “your” refer to the Grantee named in this Agreement. Capitalized terms that are not defined herein shall have the meanings ascribed to such terms in the Plan. This Agreement shall be binding on all successors and assigns of the Company.
