        <footnote id="F1">Includes 13,020 shares of restricted stock units (RSUs) the reporting person elected to receive on a deferred basis in lieu of a portion of his 2013 annual cash incentive award pursuant to the Company's Executive Stock Purchase Plan.  Also includes 13,020 RSUs representing the Company match on such deferral, subject to three year cliff-vesting.</footnote>
        <footnote id="F2">On June 14, 2011, the reporting person was granted 10,000 performance share units (PSUs) under the Company's 2008 Incentive Compensation Plan. Each PSU represented a contingent right to receive one share of common stock. As previously reported, on June 14, 2012 the pre-established performance goal for this award was met and 50% of the PSUs vested immediately. The remainder of the PSUs vested on June 14, 2013. This filing is being made to report the shares of common stock surrendered back to the Company to satisfy tax withholding obligations related to the shares that vested on June 14, 2013.</footnote>
