On August 2, 2001, H. Lawrence Culp, Jr., President and Chief Executive Officer
of Danaher Corporation ("Danaher"), sent the following letter to Danaher
associates:

Dear Danaher Associates,

An interesting day, to say the least!

Hopefully, all of you have had the chance to read the press release we issued
yesterday morning, as well as my accompanying internal letter to Danaher
associates. These two pieces of information should help you understand the
rationale behind this exciting opportunity. If you're interested in more detail,
links to Cooper's publicly available information as well as a replay of the
conference call we held for investors yesterday morning can be accessed through
mydanaher.com.

However, I know many of you are interested in more than the strategy and
mechanics of this merger.  "What happens next?" and "what does this mean for
me personally?" are the two most common questions I've heard.

The answer to the first question is simple. The Cooper Board of Directors has
indicated that it will meet next week and we are optimistic that they will
consider our proposal at that time, and agree to work with us to quickly achieve
a mutually beneficial negotiated transaction. Subsequent activities will depend
on the outcome of this Board meeting.

Regarding the second question, we think the proposed transaction is great news
for Danaher associates, though we will know much more once we have had an
opportunity to perform due diligence at Cooper - to "look under the hood," so to
speak. Although my communications are bound by certain legal restrictions (we
cannot selectively provide information only to Danaher associates), please be
assured that as relevant information becomes available I will provide it to you.
We will be using the Cooper Acquisition Info knowledge area on mydanaher.com as
a focal point for all communications.

Over the coming weeks there will be many distractions as this situation unfolds,
and you are likely to see some volatility in Danaher's share price (which is
typical in these sorts of situations). We cannot allow these issues to impact
the performance of our fine company, and I ask that you stay focused on our
strategic priorities and on delivering our usual top-notch results.

Finally, please also remember that our communications in the coming weeks may
contain certain forward-looking statements and that actual financial results may
differ from those predicted.

Sincerely,

Larry






                           FORWARD-LOOKING STATEMENTS

This presentation contains forward-looking statements within the meaning of
Section 27A of the Securities Act and Section 21E of the Securities Exchange
Act. In some cases, you can identify these so-called "forward-looking
statements" by words such as "may," "will," "expects," "plans," "believes,"
"estimates," "predicts," "potential," or words of similar tenor. These
forward-looking statements are based on management's good faith expectations and
beliefs concerning future developments, but you are cautioned that actual events
or results may differ materially from the expectations expressed in such
forward-looking statements as a result of various factors, including risks and
uncertainties, many of which are beyond the control of Danaher Corporation
("Danaher"). Factors that could cause actual results to differ materially
include, but are not limited to: (1) the businesses of Danaher and Cooper
Industries, Inc. ("Cooper") may not be integrated successfully or such
integration may be more difficult, time-consuming or costly than expected; (2)
expected combination benefits from the transaction may not be fully realized or
realized within the expected time frame; (3) Cooper may not be able to meet
Danaher's expectations and revenues following the transaction may be lower than
expected; (4) operating costs and business disruption, including difficulties in
maintaining relationships with employees, customers or suppliers, may be greater
than expected following the transaction; (5) the regulatory approvals required
for the transaction may not be obtained on the proposed terms or on the
anticipated schedule; (6) the effects of legislative and regulatory changes
(particularly environmental regulations) which could affect demand for products
in the Process/Environmental Controls segment; (7) unanticipated developments
that could occur with respect to contingencies such as environmental matters and
litigation; (8) technological changes; (9) changes in labor or capital costs;
(10) Danaher's ability to attract and retain qualified employees; (11) future
acquisitions, strategic partnerships and divestitures; (12) general business and
economic conditions; and (13) other risks described from time to time in
Danaher's periodic reports filed with the Securities and Exchange Commission
(the "SEC"). Danaher disclaims any duty to update any forward-looking
statements, all of which are expressly qualified by the foregoing.
