        <footnote id="F1">Includes 50,000 shares of the issuer's common stock, 1,286 shares of the issuer's common stock underlying restricted stock units, and 2,542 shares of deferred stock which will be distributed as actual shares of the issuer's common stock following the reporting person's cessation of board service. Each restricted stock unit will entitle the reporting person to receive one share of the issuer's common stock when that unit vests. The units will vest in full upon the reporting person's continuation in Board service through the day immediately preceding the date of the issuer's 2015 annual shareholders meeting, subject to accelerated vesting under certain prescribed circumstances.</footnote>
