        <footnote id="F1">Represents a grant of restricted common shares under the Company's Amended and Restated Incentive Award Plan. The restricted common shares vest and the restrictions cease to apply on one-third of the award on each February 15th over a three year period beginning February 15, 2019.</footnote>
        <footnote id="F2">Represents a grant of performance shares which may convert into an equivalent number of restricted common shares of the Company based on the Company's share price appreciation inclusive of all dividends (TSR), and its TSR relative to a selected group, over the three-year measurement period from February 16, 2018 through February 15, 2021.</footnote>
        <footnote id="F3">With respect to 33.30% of the performance shares, 20% of this portion of the award will be earned if the Company's aggregate TSR equals 19.1% over the 3-year measurement period, 60% of this portion of the award will be earned if the Company's aggregate TSR equals 24.23%, and 100% of this portion of the award will be earned if the Company's aggregate TSR equals or exceeds 29.5%. With respect to the other 66.70% of the performance shares, 20% of this portion of the award will be earned if the Company's TSR is in the 30th percentile of its peer group over the 3-year measurement period, 60% of this portion of the award will be earned if the Company's TSR is in the 55th percentile of its peer group during this period, and 100% of this portion of the award will be earned if the Company's TSR is in the 80th percentile of its peer group or greater during this period. The performance shares will convert on a pro-rata basis by linear interpolation between share price appreciation thresholds.</footnote>
        <footnote id="F4">Any restricted common shares earned on February 15, 2021 are subject to a time based vesting schedule. 50% of the shares will vest on February 17, 2021 and the remaining 50% will vest on February 17, 2022, contingent upon continued employment with the Company through the vesting dates.</footnote>
