        <footnote id="F1">Represents an award of performance based restricted share units. The target number of units is presented in the table. Subject to certain continued employment conditions and subject to accelerated vesting in certain circumstances, the number of units that actually vest over the four-year vesting period will be either 0% or 100% of the scheduled amount, depending on whether the Issuer meets certain performance goals at the end of the first year of the vesting period.  If the Issuer meets its performance goals at the end of the first year vesting period, then the units shall vest in four equal annual installments.</footnote>
        <footnote id="F2">Represents an award of performance-based restricted share units.  The target number of units is presented in the table. Subject to certain continued employment conditions and subject to accelerated vesting in certain circumstances, the number of units that actually vest at the end of the three-year performance period will be 0% to 250% of the scheduled amount, depending on the extent to which the Issuer meets or exceeds certain performance goals at the end of each year during the performance period. The maximum number of units that may vest at the end of the three-year performance period is 13,070 (250% of the target number).</footnote>
