VI.Clawback. This Award shall be subject to the clawback provision of Section 16(n) of the Plan and this paragraph. The Company may in its sole discretion and as allowed by law recoup amounts paid to the Executive under this Award Agreement in the event of (a) a financial restatement of the Company's previously issued financial statements as a result of errors, omission, fraud, or noncompliance with any financial reporting requirement under the securities laws, or (b) any conduct by Executive, or concerning which Executive has direct knowledge and fails to timely take action to address, that is materially adverse to the Company (such conduct to include conduct that in the reasonable opinion of the Company: (i) warrants or could warrant the Executive’s dismissal; or (ii) is a violation of the Company’s Guiding Principles, or any law, regulation or listing standard (collectively, “Violation”), whether or not such Violation results in criminal prosecution or sanctions against Executive or the Company, and whether or not the Company learns of such Violation before or after the Executive’s termination of employment). In such circumstances, the Committee shall review the facts and circumstances underlying the restatement or Violation. After this review, if it is determined that an Award amount was based on the achievement of certain financial results that were the subject of a restatement, or that the Violation subjected the Company to financial, reputational or other harm, the Committee may, in its discretion, require the Executive to reimburse the Company for all or a portion of any Award actually paid to the Executive or, if such Award has been deferred into the Non-Qualified Deferred Compensation Plan, forfeit the Award so deferred. In each such instance, the Company may forfeit (to the extent deferred) or seek to recover (to the extent paid) the amount by which the Executive's Award amount exceeded the lower amount, if any, that would have been made based on the restated financial results or the amount that, in the Company’s sole discretion, the Company was harmed by such Violation. However, if the clawback arises from a material restatement of our financial results, the Company will not seek such recovery where the payment to Executive occurred more than three years prior to the date the Company is required to prepare the applicable restatement. If the clawback relates to knowledge of materially adverse conduct, there is no time limit on recovery. The Company will determine, in its sole discretion (but subject to the direction of the

Committee), the method for obtaining reimbursement from the Executive. The Company may forfeit and/or recoup amounts paid in respect of an Award regardless of whether the Executive is still employed by the Company or an affiliate on the date forfeiture and/or reimbursement is required. Forfeiture of or recoupment of amounts paid in respect of an Award does not limit any other remedies that the Company may have.

VII.Defined Terms; Agreement. Except as otherwise specifically defined in this Award Agreement, the terms used in this Award Agreement shall have the same meaning as the terms defined in the Plan. By signing below, the Executive indicates his or her agreement to the terms of this Award Agreement and the Plan, that he or she has read this Award Agreement and the Plan, and that he or she understands that in the event of any inconsistency between the terms of this Agreement and the Plan, the terms of the Plan shall control.

VIII.Employment. This Award Agreement does not confer upon Executive any right to continue in employment, nor shall it, except during the period specified in the preceding sentence, restrict Executive’s right to terminate employment at any time.

IN WITNESS WHEREOF, the Company has caused this instrument to be executed by its duly authorized officer, and the Executive has hereunto affixed his hand and seal, the day and year first above written.
