        <footnote id="F1">These shares were retained by the Issuer in order to satisfy the tax obligations of the reporting person in connection with the vesting of shares of restricted stock.</footnote>
        <footnote id="F2">The amount reflects the forfeiture of 6,666 restricted stock units on March 12, 2019.  The acquisition of these restricted stock units, which were subject to market based vesting, was eligible to be reported on Table II of Form 4 as a derivative security, however, the Reporting Person elected to report the acquisition on Table I of a Form 4 that was filed on February 12, 2016.  Per Rule 16a-4(d), the forfeiture of such restricted stock units is not reportable.</footnote>
