On August 10, 2001, H. Lawrence Culp, Jr., President and Chief Executive Officer
of Danaher Corporation ("Danaher"), sent the following letter to Danaher

Dear Danaher Associates,

By now, many of you have read the press release issued by Cooper's Board of
Directors yesterday, as well as our response.

We are certainly disappointed that Cooper's Board has chosen to reject our offer
for the company. Based on Cooper's publicly available financial information, we
believe our offer is fair.

However, rest assured that this response does not mean the situation has ended.
The Cooper Board has stated they will explore "all strategic alternatives that
would maximize shareholder value," and has indicated we can engage in this
process. In other words, rather than negotiating with us on an exclusive basis,
they are looking at various alternatives, including putting the company up for

As I stated in my letter to Danaher associates last Wednesday, we originally
approached Cooper because we believe the combination offers compelling benefits
to shareholders of both companies. We are committed to our July 25th proposal,
and plan to smartly participate in any auction process that Cooper embarks on.
We remain hopeful that we will achieve a negotiated transaction with the Cooper
Board - but are preserving all our options.

I would like to emphasize that we are not committed to pursuing our proposal at
any cost. While we are very excited about the benefits of a merger, we also
believe Danaher has excellent prospects on its own, and are unwilling to
jeopardize the financial health of our fine company.

The next several months could certainly be interesting as this situation
unfolds. I will continue to keep you updated as relevant information becomes
available (using as my primary means of communication). As always,
amidst all these distractions I ask that you remain focused on our strategic
priorities and on delivering our usual top-notch results.

In addition, 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.



                           Forward-Looking Statements

The above letter 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 "would," "will," "expects," "plans," "believes" 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. Factors that could cause actual results to differ materially
include the following: (1) the businesses of Danaher and 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 may not be 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; and (6) other risks described from time to time in Danaher's periodic
reports filed with the Securities and Exchange Commission. Danaher disclaims any
duty to update any forward-looking statements, all of which are expressly
qualified by the foregoing.
