        <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">232 shares were withheld by the issuer to satisfy income tax withholding requirements related to the lapsing of restrictions on 950 shares of restricted stock awarded to the reporting person on May 17, 2018 (Form 4 filed on 5/15/2019).  Because the reporting person's restricted stock holdings have been included in the direct ownership of Common Stock disclosed by the reporting person, the reporting person's direct ownership of Common Stock has been reduced by 232 shares to reflect this tax withholding.</footnote>
        <footnote id="F3">This restricted stock award will vest as follows:  1,024 shares on 3/31/20; 1,024 shares on 3/31/21; 1,024 shares on 3/31/22; and 1,023 shares on 3/31/23.</footnote>
        <footnote id="F4">131 shares were withheld by the issuer to satisfy income tax withholding requirements related to the lapsing of restrictions on 537 shares of restricted stock awarded to the reporting person on May 20, 2016 (Form 4 filed on 5/24/2016).  Because the reporting person's restricted stock holdings have been included in the direct ownership of Common Stock disclosed by the reporting person, the reporting person's direct ownership of Common Stock has been reduced by 131 shares to reflect this tax withholding.</footnote>
