        <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">414 shares were withheld by the issuer to satisfy income tax withholding requirements related to the lapsing of restrictions on 987 shares of restricted stock awarded to the reporting person on 6/10/2015 (Form 4 filed on 5/10/2016).  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 414 shares to reflect this tax withholding.</footnote>
