        <footnote id="F1">The share equivalents reported herein were acquired pursuant to the Issuer's Fee Deferral Plan for Directors. The Reporting Person elected to defer receipt of 5,850 restricted stock units into an equal number of share equivalents. The restricted stock units represent the equity portion of the annual retainer fee in the amount of $225,000, with the number of units determined by dividing the dollar amount of the fees by $38.455, the average of the high ($38.75) and low ($38.16) price of the Issuer's common stock on the fee payment date. Additional share equivalents accrue as and when dividends are paid on the Issuer's common stock. Share equivalents are paid in an equal number of shares of the Issuer's common stock upon the Reporting Person's termination of service as a director.</footnote>
        <footnote id="F2">Reported holdings include shares acquired since the Reporting Person's last filing on Form 4 from dividend reinvestment transactions exempt from Section 16 of the Securities Exchange Act of 1934, as amended.</footnote>
