Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensation Arrangements of Certain Officers.

On April 27, 2010, the Board of Directors of Trimble Navigation Limited (“Trimble” or the “Company”) amended Trimble’s Annual Management Incentive Plan (“the Plan”). The amendments to the Plan permit the Board of Directors and the Chief Executive Officer (the “CEO”) to use the Company’s Operating Income, as that term is defined in the Plan, to establish the performance goals for participants.

The Plan amendments also increase the maximum possible payouts under the Plan from 200% to 300% of each participant’s target for the CEO and the Company’s named executive officers. In addition, payments under the Plan are made on a quarterly basis, at 15% of target each quarter and the remainder after the close of the respective fiscal year based on achievement of the quarterly or annual goals.

The foregoing description of the Plan, and the amendments to the Plan, is qualified in its entirety by the Plan, which is attached hereto as Exhibit 10.1, and is incorporated herein by reference.

4. Target payouts, ranging from 10% to 125% of base annual salary for each participant are determined by the CEO of the Company in conjunction with the executive officers and the vice presidents of the Company, and approved by the Board of Directors. The Board of Directors has established a 125% target for the CEO.
