Dear Tektronix employee,

On behalf of Danaher Corporation, I am delighted at the prospect of welcoming you to the Danaher family! Although Danaher’s acquisition of Tektronix requires satisfaction of customary closing conditions, we look forward to having you join our team once the acquisition officially closes. We are hopeful that this will occur by the end of 2007.

We know you have many questions about the upcoming transition. We will do everything possible to ensure that Tektronix’s transition into the Danaher Electronic Test platform is a smooth one.

Tektronix and Fluke are two of the best brands in Test and Measurement with combined served marketplaces of $12 billion and we are extremely excited about the opportunities for future growth and innovation. Both companies have a rich history of success in the Test and Measurement industry. There are many similarities between the two companies upon which to build a common mission. Tektronix is synonymous with leading edge technology and quality to the R&D engineer, just as Fluke is to the service, installation and maintenance professional. Both also have vital communications/network businesses with significant growth potential.

We have always had the utmost respect for Tektronix. Over the past few months, as the Danaher team has gotten to know Tektronix we have been impressed by what we have seen: a highly capable group of associates that place a premium on taking care of the customer, an outstanding management team, an entrepreneurial spirit, product innovation, and a stellar brand name. Even our location in the Pacific Northwest gives us another common bond that we can build on.

Tektronix will continue to operate as a stand-alone business within Danaher’s Electronic Test platform and the headquarters will remain in Beaverton, Oregon. Rick Wills, Tektronix Chairman and CEO, will report to me. All other Tektronix associates will continue their current reporting relationships.

Again, we look forward to having you on our team. We appreciate your patience and understanding as we make the transition. Please let us know how we can assist you through this process.

Sincerely yours,

Jim Lico Danaher Executive Vice President
