        <footnote id="F1">The SSARs are granted pursuant to the Dover Corporation 2005 Cash and Equity Incentive Plan (the &quot;Plan&quot;).  Subject to shareholder approval, Dover Corporation has adopted amendments to the Plan to provide for the grant of performance shares.  In addition to the SSARs reported above, the Reporting Person has been granted alternative awards of 5,432 performance shares or 21,728 additional SSARs, contingent upon the result of the shareholder vote on the proposed amendments to the Plan (the performance share award being void in the event that the shareholders do not approve the amendments to the Plan and the SSAR award being void in the event that the shareholders do approve the amendments).  In accordance with Section 16(a), the award of performance shares or SSARs, as applicable, will be reported after the contingency for the award has been satisfied at the shareholders' meeting.</footnote>
