        <footnote id="F1">Represents 416 shares of common stock of the issuer withheld by the issuer in satisfaction of the applicable withholding taxes on certain shares of common stock that became issuable on January 4, 2017 pursuant to the terms of the January 4, 2016 Restricted Stock Unit Issuance Agreement between the reporting person and the issuer since the performance objective was attained. The issuable shares were previously reported as Table I securities at the time the restricted stock units were granted, and accordingly the issuance of those shares is not a reportable transaction on this Form 4.</footnote>
        <footnote id="F2">Includes 3,840 shares of issuer's common stock and 5,185 shares of the issuer's common stock underlying restricted stock units.</footnote>
