         Dear Steve:

                Thank you very much for the time spent during our recent series
         of discussions. I hope the opportunity to meet with some of our key
         executives, review some of our strategies and tour a few factories
         helped you see first-hand the positive and highly effective culture we
         enjoy at Danaher. We share your enthusiasm and look forward to your
         becoming a part of the Danaher team.

                I am pleased to present you with the following offer of
         employment.

                Title:                  Group Executive & Corporate Vice

                                                               -----------
                                        Target Total:          $405,450.00

                Your initial Group Executive assignment will include more than
         $400 million in revenue, including full P&L and operational
         responsibility for the Professional Tool Division, Matco Tools and
         Hennessy Industries. You will take direct management control of the
         Professional Tool Division in the capacity of President, with
         Matco/Hennessy reporting to you through a President.

         Compensation Plan (ICP) on a full year basis. Normally, ICP payments
         are made during the first quarter of the following year. In addition,

provide you with long term earnings based on the continued appreciation of
Danaher Corporation stock. You will also be provided with a company car as well
as a country club membership.

        You will participate in the Danaher Associate Stock Option Program. This

on each of your first three anniversary dates, the actual transfer of ownership
will occur following your third anniversary.

        You will be eligible for all regular exempt associate benefits (with the
exception of severance benefits as noted below), and you will be eligible for
comprehensive medical, dental and life insurance benefits immediately upon your
first day of employment. With respect to severance benefits, should your

them or have any questions on benefits, please feel free to call Dennis Longo at
your convenience.
