        <footnote id="F1">Each Performance Stock Unit represented a contingent right for the reporting person to receive a distribution of common shares of the issuer equal to 0% to 200% of a target number of Performance Stock Units equal to 66,667.  The actual number of shares distributed has been determined based on the issuer's total stockholder return (TSR) performance during the performance period of 1/1/2015 through 12/31/2015 (the &quot;Completed Performance Period&quot;).  The vesting for 50% of the target Performance Stock Units was determined based upon the issuer's absolute TSR for the Completed Performance Period as compared to a matrix of fixed numeric values and the vesting for the other 50% of the target Performance Stock Units was determined based upon a relative comparison of the issuer's TSR to the Vanguard Russell 2000 exchange traded fund TSR for the Completed Performance Period.</footnote>

The actual number of shares distributed will be based on the issuer's total stockholder return (TSR) performance during the performance period of 1/1/2016 through the earlier of 12/31/2016 or a change in control of the issuer (&quot;Performance Period&quot;).  The vesting for 50% of the target Performance Stock Units is based upon the issuer's absolute TSR for the Performance Period as compared to a matrix of fixed numeric values and the vesting for the other 50% of the target Performance Stock Units is based upon a relative comparison of the issuer's TSR to the Vanguard Russell 2000 exchange traded fund TSR for the Performance Period.</footnote>
        <footnote id="F4">The vesting and distribution conditions for the reported target Performance Stock Units are the same as described under footnote (1), except that the Performance Period is 1/1/2017 through the earlier of 12/31/2017 or a change in control of the issuer.</footnote>
