        <footnote id="F1">In accordance with the issuer's Amended and Restated Incentive Plan, this price represents the closing price per share of Common Stock on the previous trading day.</footnote>
        <footnote id="F2">1,032 shares were withheld by the issuer to satisfy income tax withholding requirements related to the lapsing of restrictions on (a) 589 shares of restricted stock awarded to the reporting person on May 18, 2017 (Form 4 filed on 5/22/2017); (b) 879 shares of restricted stock awarded to the reporting person on May 20, 2016 (Form 4 filed on 5/24/2016) and (c) 1,161 shares of restricted stock awarded to the reporting person on June 10, 2015 (Form 4 filed on 5/10/2016).  Because the reporting person's restricted holdings have been included in the direct ownership Common Stock disclosed by the reporting person, the reporting person's direct ownership of Common Stock has been reduced by 1,032  shares to reflect this tax withholding.</footnote>
