        <footnote id="F2">Performance Units were granted on February 22, 2017, subject to achievement of performance period criteria for a three-year period, ending upon the close of the Company's 2019 fiscal year.  The number of units reported assume the Company meets target performance criteria at the end of 2019; actual units earned will be adjusted based on actual performance against the performance criteria.  Any earned units will vest on February 22, 2020, at which time each earned and vested unit will convert to one share of the Company's common stock.</footnote>
