Dear Chris:

Trimble Navigation Limited (“Trimble”) is pleased to offer you a transfer from
your current exempt position as General Manager, salary grade 99, reporting to
Bryn Fosburgh, to the same position in Colorado. In the new location your salary
will be paid on a bi-weekly basis aggregating to the equivalent of two-hundred
and thirty-five thousand dollars (USD$235,000), annualized. You will continue to
participate in Trimble’s 2008 Management Incentive Plan for a potential target
bonus of 35%, depending on company performance.

In addition, Trimble will provide partial continuity for your pension plan. An
international contribution of 5% match of base salary and bonus payments may be
made upon meeting specific criteria as outlined in a separate document. An
option to select an alternative pension scheme may be in place before year-end;
should this second option be made available you must state your preference of
plans before January 1, 2009. The ten years of prior Trimble service accrued to
date will be bridged according to company policy.

This offer is also pending the successful completion of the immigration process
to secure a temporary visa. If you voluntarily terminate employment within one
year of your hire date, Trimble will seek pro-rated reimbursement of these visa
expenses, except where prohibited by law. In addition, Trimble will assist you
with your relocation, to be processed by GMAC in accordance with the company’s
relocation policy and those benefits approved for you. Further information on
the policy and specific benefits available to you will be provided by GMAC and
Trimble’s Global Mobility organization.

Should Trimble terminate your employment, for any reason other than gross
misconduct, your repatriation to England at Company expense is assured.
Repatriation benefits also apply if you resign for the express purpose of
retirement in England but not before the year 2016. Resignation, for any other
cause, negates Trimble’s need to pay or assist with a subsequent relocation.

All relocation benefits are provided contingent upon your signing a Relocation
Repayment Agreement, which will be provided by GMAC. Among other things, this
agreement notes the required full repayment of the gross value of any benefits
provided to you within one year of a voluntary termination from Trimble or any
of its subsidiaries or affiliate companies. No benefits will be provided until
this agreement is signed and returned to your GMAC relocation representative.
Upon acceptance of your employment offer or if you have any questions about the
relocations benefits being offered to you, please contact Linnea Hickman at
(408) 481-8650.

--------------------------------------------------------------------------------

This offer is in compliance with the Immigration Reform and Control Act of 1986,
which requires the Company to verify that each employee hired is legally
entitled to work in the United States.

A copy of the ‘List of Acceptable Documents’ as published by the Citizenship and
Immigration Services (CIS) will follow at a later time. Please be prepared to
bring one document from list “A” or one document from both List “B” and “C.”
This information must be provided at your New Hire Orientation. Failure to
provide this information, as required by law, may result in termination.

Trimble is an “at will” employer, meaning that the employer or employee can
terminate the employment relationship at any time, with or without cause. Should
you choose to resign from Trimble we request one year’s advance notice. In
return, Trimble guarantees to provide one year’s notice prior to termination, or
the equivalent pay in lieu of said notice; except in the event of gross
misconduct. While other terms of your employment may change from time to time,
the “at will” term and nature of your employment will not change.

Chris, Trimble’s success is derived from the people who work here. Your
acceptance of this offer will be enthusiastically received and we feel confident
that you will continue to make a significant contribution to our success.

You may accept this offer in writing “electronically” by inserting your name in

We request a reply from you no later than 9 June 2008 in order for this offer to

further information regarding the immigration process and local Orientation,
including additional documents you will be required to return.

Please call me if you have any questions or if I can be of additional
assistance. I can be reached at (720) 587 4462.
