        <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">1,819 shares were withheld by the issuer to satisfy income tax withholding requirements related to the lapsing of restrictions on (a) 1,024 shares of restricted stock awarded to the reporting person on 5/16/19 (Form 4 filed 5/20/19); (b) 1,833 shares of restricted stock awarded to the reporting person on May 17, 2018 (Form 4s filed 5/21/18 and 5/15/19); (c) 2,002 shares of restricted stock awarded to the reporting person on May 18, 2017 (Form 4s filed 5/22/17 and 5/9/18); (d) 1,562 shares of restricted stock awarded to the reporting person on May 20, 2016 (Form 4 filed 5/12/17); and (e) 986 shares of restricted stock awarded to the reporting person on June 10, 2015 (Form 4 filed 5/10/16).  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 1,819 shares to reflect this tax withholding.</footnote>
