        <footnote id="F1">In connection with the vesting of 3,074 restricted stock units held by the Reporting Person on 03/06/2018, the Issuer has withheld 749 shares of common stock to satisfy the resulting tax withholding obligation.  The withholding of these shares occurred automatically upon the vesting of the restricted stock units, and as such, no investment decision was made by the Reporting Person in connection with this transfer.</footnote>
        <footnote id="F2">The sale reported on this Form 4 was effected pursuant to a Rule 10b5-1 trading plan to pay taxes on the vesting of certain share awards from which no shares could be withheld to pay the taxes.  The transaction was executed in multiple trades at prices ranging from $57.05 to $57.70.  The price reported above reflects the weighted average sale price.  The reporting person hereby undertakes to provide upon request to the SEC staff, the issuer or a security holder of the issuer full information regarding the number of shares sold at each separate price within the range set forth in the footnote.</footnote>
