        <footnote id="F1">The reported transaction was effected for estate planning purposes.</footnote>
        <footnote id="F2">The reported transaction reflects a gift by the reporting person to the Garett G. Essl Trust, an irrevocable trust for the benefit of the reporting person's son.  The reporting person and his wife act as trustees of the trust.</footnote>
        <footnote id="F3">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="F4">2,687 shares were withheld by the issuer to satisfy income tax withholding requirements related to the lapsing of restrictions on (a) 930 shares of restricted stock awarded to the reporting person on May 18, 2017 (Form 4 filed on 5/22/2017); (b) 1,563 shares of restricted stock awarded to the reporting person on May 20, 2016 (Form 4 filed on 5/24/2016); (c) 987 shares of restricted stock awarded to the reporting person on June 10, 2015 (Form 4 filed on 5/10/2016); (d) 1,459 shares of restricted stock awarded to the reporting person on 6/03/2014 (Form 4 filed on 5/7/2015) and (e) 1,897 shares of restricted stock awarded to the reporting person on 8/12/2013 (Form 4 filed on 5/08/2014).  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 2,687 shares to reflect this tax withholding.</footnote>
