        <footnote id="F2">All shares represented by restricted share units which are scheduled to vest, subject to the Reporting Person's continued employment.  Each restricted share unit represents a contingent right to receive one share of the Issuer's common stock.</footnote>
        <footnote id="F3">These performance rights were granted on February 17, 2016 and vest at specified percentages upon achieving specified stock price targets (based on a 45-day trailing average stock price) during a four-year measurement period.  On January 6, 2017, the Reporting Person was entitled to receive 40% of the target shares subject to these performance rights as a result of the Issuer's common stock achieving the specified stock price. Each performance right represents a contingent right to receive one share of the Issuer's common stock, subject to an additional one-year time-based vesting requirement for any portion of the award that is earned during the first three years of the measurement period.</footnote>
