        <footnote id="F1">Compensation deferred or contributed into the Danaher stock fund (the &quot;EDIP Stock Fund&quot;) included in Danaher's Executive Deferred Income Plan (the &quot;EDIP&quot;) is deemed to be invested in a number of unfunded, notional shares of Danaher common stock based on the closing price of Danaher common stock as reported on the NYSE on the date such compensation is credited to the EDIP Stock Fund.  The price shown in Table II, Column 8 above is the closing price per share of Danaher common stock as reported on the NYSE on April 30, 2004.</footnote>
        <footnote id="F2">The notional shares convert on a one-for-one basis.</footnote>
        <footnote id="F3">The reporting person immediately vests in 100% of each voluntary contribution to the EDIP Stock Fund.  The reporting person will vest in all company contributions to the EDIP Stock Fund as follows: 100% upon the earlier of the reporting person's death, or upon retirement following at least 5 years of service with Danaher and reaching the age of 55, or, if earlier, 10% per vesting year of participation following five vesting years of participation, in each case in accordance with the plan.  Upon termination of employment, the vested portion of the EDIP Stock Fund is settled in Danaher common stock.</footnote>
