        <footnote id="F1">Each PRSU represents a contingent right to receive one share of common stock upon vesting.</footnote>
        <footnote id="F2">The reported number of securities represents the Tranche 1 2018 PRSUs (as defined in footnote 3) that were deemed earned on February 6, 2019 (following certification of the performance metric for the applicable performance period) and that vest on December 31, 2020, which is the same vesting as for the Tranche 2 2018 PRSUs (as defined in footnote (3).</footnote>
        <footnote id="F3">In 2018, Kimberly L. Dickens was granted an award of PRSUs (&quot;2018 PRSUs&quot;), split into four equally-weighted tranches, to be earned based on performance against predetermined Adjusted EBITDA and Adjusted Earnings Per Share performance goals over four equally-weighted measurement periods within the three-year period beginning January 1, 2018 and ending December 31, 2020. The first tranche of 2018 PRSUs (&quot;Tranche 1 2018 PRSUs&quot;) was to be earned based on performance of predetermined Adjusted EBITDA and Adjusted Earnings Per Share performance goals during the period of January 1, 2018 to December 31, 2018.  The second tranche of 2018 PRSUs (&quot;Tranche 2 2018 PRSUs&quot;) was to be earned based on performance of predetermined Adjusted EBITDA and Adjusted Earnings Per Share performance goals during the period of January 1, 2019 to December 31, 2019.</footnote>
        <footnote id="F4">(Continued from footnote 3) The third tranche of 2018 PRSUs (&quot;Tranche 3 2018 PRSUs&quot;) was to be earned based on performance of predetermined Adjusted EBITDA and Adjusted Earnings Per Share performance goals during the period of January 1, 2020 to December 31, 2020. The fourth tranche of 2018 PRSUs (&quot;Tranche 4 2018 PRSUs&quot;) was to be earned based on performance of predetermined cumulative Adjusted EBITDA and Adjusted Earnings Per Share performance goals during the three-year period of January 1, 2018 to December 31, 2020.  Each tranche would be deemed earned, if at all, following the certification of performance goal attainment by the Compensation Committee following the applicable performance period and would vest, subject to continued employment through such date, on December 31, 2020.</footnote>
