PRESS RELEASE : Danaher To Acquire Textronix

Tektronix Board of Directors unanimously recommends acceptance of all-cash offer
Addition of Tektronix would significantly expand Danaher's leading global position in Electronic Test

Washington, D.C. and Beaverton, Ore., October 15, 2007 – Danaher Corporation (NYSE: DHR) and
Tektronix, Inc. (NYSE: TEK) today announced they have reached a definitive agreement under which
Danaher will make a cash tender offer to acquire all of the outstanding common shares of Tektronix
for $38.00 per share. The aggregate purchase price is approximately $2.8 billion, including debt,
transaction costs and net of cash acquired.

The Board of Directors of Tektronix has unanimously recommended that Tektronix shareholders
accept and tender their shares into the offer, which represents a premium of approximately 34% to
Tektronix's closing price on October 12, 2007. The offer is subject to customary conditions, including
tender of a majority of the outstanding shares into the offer (on a fully diluted basis but excluding
any shares issuable pursuant to the Tektronix Notes), regulatory approvals, and the absence of a
material adverse change with respect to Tektronix. The transaction is expected to be completed in
the fourth quarter of 2007.

With annual revenues of approximately $1.1 billion, Tektronix is a leading supplier of test,
measurement, and monitoring products enabling the design, manufacture, and management of
next-generation global communications networks, computing and advanced technologies.
Tektronix's products and solutions address the needs of industry leaders in the communications,
computer, semiconductor and consumer electronics -- as well as military/aerospace, education and
a broad range of other industries.

Tektronix would become part of Danaher's Electronic Test platform, joining Danaher's Fluke and
Fluke Networks businesses, and nearly doubling the platform's revenues. The combined brands are
some of the most highly recognized in each of their respective product segments.

Danaher's President and CEO, H. Lawrence Culp, Jr., said, "With its well recognized brand,
significant global reach and broad based expertise in providing solutions for end-users in research
and product development for high-growth industries we believe Tektronix provides an excellent
complement to our existing Electronic Test business. We have long admired Tektronix's product
innovation and excellent reputation. Through the application of the Danaher Business System we
believe we can continue to deliver strong results in our established businesses and look at attractive
adjacent markets for future growth opportunities. We are very pleased to welcome Tektronix's
management team and associates to Danaher."

Richard H. Wills, Chairman of the Board, President and Chief Executive Officer of Tektronix, said,
"The combination of Danaher and Tektronix enables us to leverage each other's strengths and build
on our commitment to long-term growth, innovation and continuous productivity improvement. We
believe this is a compelling transaction for Tektronix shareholders and that the combined efforts of
Danaher and Tektronix will extend the leadership position we have built in our served markets
throughout the world."

The transaction will be a "fundamental change" under the terms of the indenture governing
Tektronix's $345 million aggregate principal amount 1.625% Senior Convertible Notes due 2012,
which will entitle the noteholders to convert their notes into a cash amount based on the value of a
certain number of common shares to be determined by a formula set forth in the indenture.

Danaher and Tektronix will hold a conference call today at 9:00 a.m. EDT to discuss this transaction. The U.S.dial-in number is 888-204-4519; the international dial-in number is 913-312-9330; with reference ID Code 9416681.
