        <footnote id="F1">This Amendment is being filed solely to correct a typographical error in the footnote to Column 4 of Table I. The footnote in the original filing incorrectly referred to sale rather than purchase.</footnote>
        <footnote id="F2">The price reported in Column 4 is a weighted average price. These shares were purchased in multiple transactions at prices ranging from $66.43 to $66.48, inclusive. The reporting person undertakes to provide to Dover Corporation, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares purchased at each separate price within the ranges set forth in footnote (2) to this Form 4.</footnote>
        <footnote id="F3">Shares held jointly with spouse; amount reflects correction of prior computational error.</footnote>
        <footnote id="F4">Each performance share represents a contingent right to receive shares of Dover common stock, based on Dover's relative total shareholder return versus that of Dover's peer group over the three-year performance period ending 12/31/2013.</footnote>
        <footnote id="F5">Represents target grant amount.  The actual number of shares that will be paid in respect of the performance share award may range from 0% to 200% of the target grant.</footnote>
