        <footnote id="F1">Pursuant to an Agreement and Plan of Merger, each share of common stock was converted into the right to receive $16.26 per share in cash (the &quot;Merger Consideration&quot;).  Each outstanding stock option was cancelled in exchange for the right to receive a cash payment of an amount equal to the product of (i) the total number of shares of common stock underlying such stock option and (ii) the excess of the (x) Merger Consideration over the (y) per-share exercise price of the stock option.  Each outstanding SAR was cancelled in exchange for the right to receive a cash payment of an amount equal to the product of (i) the total number of shares of common stock underlying each such SAR and (ii) the excess, if any, of (x) the Merger Consideration over (y) the per-share SAR Price.</footnote>
