                        DANAHER EXTENDS TENDER OFFER FOR
                  KOLLMORGEN CORPORATION THROUGH JUNE 14, 2000

FOR RELEASE MONDAY, JUNE 12, 2000
---------------------------------


      WASHINGTON, D.C. - Danaher Corporation (NYSE: DHR) announced today that it
is extending its tender offer for all outstanding shares of common stock of
Kollmorgen Corporation (NYSE: KOL) and associated preferred share purchased
rights from the prior expiration date of midnight on Friday, June 9, 2000, to
5:30 p.m. on Wednesday, June 14, 2000. Accordingly, the tender offer and
withdrawal rights will expire at 5:30 p.m., Eastern time, on June 14, 2000,
unless Danaher further extends the tender offer. According to a preliminary
count by the depositary for the offer, there were tendered and not withdrawn
8,515,541 shares as of 12:00 midnight on June 9, 2000 (excluding 1,258,935
shares listed on notices of guaranteed delivery received by the depositary),
representing approximately 82.2 % of the shares of Kollmorgen common stock
currently outstanding.

      Danaher is extending the offer so that more than 90 percent of the shares
of Kollmorgen common stock may be validly tendered and not withdrawn prior to
the expiration of the offer. If that occurs, Danaher will be able to use the
expedited procedures available under New York law for a merger with a 90
percent-owned subsidiary.

      Kollmorgen Corporation is one of the major worldwide manufacturers
of high performance electronic motion control products and systems.
