Item 1.01. Entry into a Material Definitive Agreement.

          Cash Bonus Plan

          On April  15,  2005,  the Board of  Directors  of  Trimble  Navigation
Limited  ("the  Company"),   taking  into  account  the  recommendation  of  the
Compensation Committee, approved a cash bonus plan for the 2005 fiscal year. The
Company's CEO, all other executive  officers and a number of other  senior-level
employees are eligible participants in the Plan. Bonuses to participants will be
based upon the achievement of operating  income, as adjusted by an asset charge,
with minimum  thresholds  for revenue and  operating  income as a percentage  of
revenue.  Target  payouts  range from 10% to 70% of base  annual  salary.  Bonus
payments for 2005 could be up to 300% of each participant's target. Payments are
made on a quarterly  basis,  10% of target each quarter and the remainder  after
the close of the fiscal year.

           On April 15, 2005,  the Board of  Directors  approved an amendment to
and restatement of the Company's  nonqualified  Deferred  Compensation Plan (the
"Plan").  The Plan was  amended to conform  to certain  changes in the  recently
enacted federal legislation affecting nonqualified deferred compensation,  which
was included in The American Jobs  Creation Act of 2004.  The restated Plan also
