        <footnote id="F1">Represents shares of Common Stock issued to the reporting person for the 2017 performance period under the Company's Executive Incentive Bonus Plan (the &quot;Bonus Plan&quot;). All shares will be issued pursuant to the Company's 2010 Equity Incentive Plan. Grant amounts were determined based on the award amount earned under the Bonus Plan and the closing price of the Company's Common Stock in trading on the New York Stock Exchange on February 23, 2018.  Delivery of shares of Common Stock will occur on February 27, 2018.  Shares withheld by the Company to satisfy tax withholding obligations (and the net issuance) will be based on the closing price of the Company's Common Stock in trading on the New York Stock Exchange on February 27, 2018 and will be reported on a subsequently filed Form 4.</footnote>
