(&quot;TE&quot;) on December 8, 2010 (the &quot;Acquisition&quot;) pursuant to an agreement and plan of merger dated July 12, 2010, as amended July 24, 2010 (the &quot;Merger Agreement&quot;), these shares of Company common stock were canceled and automatically converted into the right to receive $12.75 per share in cash, without interest and less any applicable withholding taxes.</footnote>
        <footnote id="F2">In connection with the Acquisition, this option vested in accordance with the terms of its applicable option award agreement, was assumed by TE and replaced with an option to purchase a number of shares of TE common stock equal to the number of shares of Company common stock based on a formula set forth in the Merger Agreement.</footnote>
        <footnote id="F3">Settled one-for-one in shares of Company common stock.</footnote>
        <footnote id="F4">In connection with the Acquisition, these restricted stock units were canceled in exchange for the right to receive an amount equal to the total number of shares of common stock represented by such restricted stock units at target multiplied by $12.75 per share, less any applicable withholding taxes.</footnote>
