        <footnote id="F1">The securities represent deferred shares of the issuer's common stock credited to the reporting person's deferred compensation account pursuant to dividend equivalent rights. Those rights resulted initially in the addition of cash sums to the account equal to the dividends which would have been paid during the 2016 calendar year on the deferred stock credited to such account had that stock actually been issued and outstanding on each dividend payment date, and the accumulated sums were then converted into additional shares of deferred stock on January 3, 2017 based on the average of the closing selling prices of the issuer's common stock on each of the dates during the 2016 calendar year on which actual dividends on the common stock were paid.</footnote>
        <footnote id="F2">Includes 21,598 shares of the issuer's common stock underlying RSUs that will vest and become issuable in accordance with their terms and 117,330 shares of the issuer's common stock underlying deferred restricted stock.</footnote>

The issuable shares were previously reported as Table I securities at the time the RSUs were granted, and accordingly the issuance of those shares is not a reportable transaction on this Form 4.</footnote>
