        <footnote id="F1">This award represents the equity portion of the Reporting Person's quarterly retainer for service as a director of the Issuer. The number of shares awarded was determined by dividing the dollar value of the equity portion by the price shown, which was the closing price of one share of the Issuer's common stock on the day immediately prior to the most recent scheduled quarterly board meeting, and rounding up to the next whole share.</footnote>
