                            (as amended May 5, 1998)


     The following constitute the provisions of the Employee Stock Purchase Plan
of Trimble Navigation.

     1. Purpose.  The purpose of the Plan is to provide employees of the Company
and its Designated  Subsidiaries with an opportunity to purchase Common Stock of
the Company through accumulated  payroll deductions.  It is the intention of the
Company to have the Plan  qualify as an  "Employee  Stock  Purchase  Plan" under
Section 423 of the Internal Revenue Code of 1986, as amended.  The provisions of
the  Plan  shall,   accordingly,   be  construed  so  as  to  extend  and  limit
participation  in a manner  consistent with the  requirements of that section of
the Code.

other non-cash  compensation.  Notwithstanding  the foregoing,  the Employee may
elect to exclude bonuses from the calculation of compensation.

          (f)  "Continuous  Status as an Employee" shall mean the absence of any
interruption or termination of service as an Employee.  Continuous  Status as an
Employee  shall not be considered  interrupted in the case of a leave of absence
agreed to in writing by the Company, provided that such leave is for a period of
not more  than 90 days or  reemployment  upon the  expiration  of such  leave is
guaranteed by contract or statute.

          (g) "Designated  Subsidiaries"  shall mean the Subsidiaries which have
been  designated  by the  Board  from  time to time in its  sole  discretion  as
eligible to participate in the Plan.

          (l) "Plan" shall mean this Employee Stock Purchase Plan.

          (m)  "Subsidiary"  shall mean a corporation,  domestic or foreign,  of
which  not less  than 50% of the  voting  shares  are held by the  Company  or a
Subsidiary, whether or not such corporation now exists or is hereafter organized
or acquired by the Company or a Subsidiary.

     3. Eligibility.

          (a) Any Employee as defined in  paragraph 2 who has been  continuously
employed by the Company for at least two (2) consecutive months and who shall be
employed  by the  Company  on a given  Enrollment  Date  shall  be  eligible  to
participate in the Plan. However, notwithstanding the foregoing, for purposes of
the first  Offering  Period only,  any  Employee  defined in paragraph 2 who was
employed by the Company as of August 9, 1988 shall be eligible to participate in
the Plan.

          (b) Any  provisions  of the Plan to the contrary  notwithstanding,  no
Employee shall be granted an option under the Plan (i) if, immediately after the
grant,  such  Employee (or any other person whose stock would be  attributed  to
such  Employee  pursuant to Section  425(d) of the Code) would own stock and /or
hold outstanding  options to purchase stock possessing five percent (5%) or more

Company or of any  subsidiary  of the Company,  or (ii) which permits his or her
rights to purchase  stock under all employee stock purchase plans of the Company
and its  subsidiaries  to accrue at a rate which  exceeds  Twenty-Five  Thousand
Dollars  ($25,000)  worth of stock  (determined  at the fair market value of the
shares at the time such option is granted) for each  calendar year in which such
option is outstanding at any time.

     4. Offering Periods.  The Plan shall be implemented by consecutive Offering
Periods with a new Offering  Period  commencing on or about January 1 and July 1
of each year; provided,  however,  that the first Offering Period shall commence
on or about August 15, 1988. The Plan shall continue thereafter until terminated
in accordance  with  paragraph 19 hereof.  Subject to the  shareholder  approval
requirements  of paragraph  19, the Board of Directors of the Company shall have
the power to change the  duration of  Offering  Periods  with  respect to future
offerings  without  shareholder  approval if such change is  announced  at least
fifteen (15) days prior to the scheduled  beginning of the first Offering Period
to be affected.

     5. Participation.

          (a) An  eligible  Employee  may  become a  participant  in the Plan by
completing a subscription  agreement  authorizing payroll deductions in the form
of Exhibit A to this Plan and filing



                                       55





it with the  Company's  payroll  office at least five (5) business days prior to
the applicable  Enrollment Date, unless a later time for filing the subscription
agreement is set by the Board for all eligible Employees with respect to a given
Offering Period.

          (b) Payroll  deductions for a participant  shall commence on the first
payroll  following the Enrollment  Date and shall end on the last payroll in the
Offering  Period  to which  such  authorization  is  applicable,  unless  sooner
terminated by the participant as provided in paragraph 10.

     6. Payroll Deductions.

          (a) At the time a participant files his or her subscription agreement,
he or she shall elect to have payroll  deductions made on each payday during the
Offering Period in an amount not exceeding ten percent (10%) of the Compensation
which he receives on each payday during the Offering  Period,  and the aggregate
of such  payroll  deductions  during the  Offering  Period  shall not exceed ten
percent (10%) of the participant's  aggregate  Compensation during said Offering
Period.  (b) All payroll  deductions made for a participant shall be credited to
his or her account  under the Plan. A  participant  may not make any  additional
payments into such account.

          (c) A participant may discontinue his or her participation in the Plan
as provided in paragraph 10, or may decrease,  but not increase, the rate of his
or her payroll  deductions during the Offering Period (within the limitations of
Section  6(a)) by  completing  or filing  with the  Company  a new  subscription
agreement  authorizing a change in payroll  deduction  rate.  The change in rate
shall be  effective  with the  first  full  payroll  period  following  five (5)
business days after the Company's receipt of the new subscription  agreement.  A
participant's  subscription  agreement  shall  remain in effect  for  successive
Offering  Periods unless revised as provided herein or terminated as provided in
paragraph 10.

          (d) Notwithstanding  the foregoing,  to the extent necessary to comply
with Section  423(b)(8) of the Code and paragraph 3(b) herein,  a  participant's
payroll  deductions  may be  decreased  to 0% at such time  during any  Offering
Period which is scheduled to end during the current  calendar year (the "Current
Offering  Period")  that the  aggregate  of all  payroll  deductions  which were
previously  used to  purchase  stock under the Plan in a prior  Offering  Period
which ended during that  calendar year plus all payroll  deductions  accumulated
with respect to the Current  Offering Period equal $21,250.  Payroll  deductions
shall  recommence  at the  rate  provided  in  such  participant's  subscription
agreement at the  beginning of the first  Offering  Period which is scheduled to
end in the following  calendar  year,  unless  terminated by the  participant as
provided in paragraph 10.

     7. Grant of Option.

          (a) On the  Enrollment  Date of each  Offering  Period,  each eligible
Employee  participating  in such  Offering  Period shall be granted an option to
purchase on each  Exercise  Date during such  Offering  Period up to a number of
shares of the Company's  Common Stock  determined  by dividing  such  Employee's
payroll  deductions  accumulated prior to such Exercise Date and retained in the
Participant's  account as of the Exercise Date by the lower of (i)  eighty-five
percent (85%) of the fair market



                                       56





value of a share of the Company's  Common Stock on the  Enrollment  Date or (ii)
eighty-five  percent  (85%) of the fair market value of a share of the Company's
Common Stock on the Exercise  Date;  provided that in no event shall an Employee
be  permitted  to  purchase  during each  Offering  Period more than a number of
shares determined by dividing $12,500 by the fair market value of a share of the
Company's  Common Stock on the Enrollment  Date, and provided  further that such
purchase  shall be subject to the  limitations  set forth in Section 3(b) and 12
hereof.  Exercise of the option shall occur as provided in Section 8, unless the
participant  has withdrawn  pursuant to Section 10, and shall expire on the last
day of the Offering Period. Fair market value of a share of the Company's Common
Stock shall be determined as provided in Section 7(b) herein.

          (b) The  option  price  per  share of the  shares  offered  in a given
Offering  Period  shall be the lower of: (i) 85% of the fair  market  value of a
share of the Common Stock of the Company on the Enrollment  Date; or (ii) 85% of
the fair  market  value of a share of the  Common  Stock of the  Company  on the
Exercise  Date.  The fair market value of the Company's  Common Stock on a given
date shall be determined by the Board in its discretion; provided, however, that
where there is a public market for the Common  Stock,  the fair market value per
share shall be the closing  price of the Common Stock for such date, as reported
by the NASDAQ  National  Market  System,  or, in the event the  Common  Stock is
listed on a stock exchange, the fair market value per share shall be the closing
price on such exchange on such date, as reported in the Wall Street Journal.

     8.  Exercise of Option.  Unless a  participant  withdraws  from the Plan as
provided in  paragraph  10 below,  his or her option for the  purchase of shares
will be exercised  automatically on the Exercise Date, and the maximum number of
full shares  subject to option shall be purchased  for such  participant  at the
applicable  option price with the accumulated  payroll  deductions in his or her
account.  No  fractional  shares will be  purchased  and any payroll  deductions
accumulated  in a  participant's  account which are not used to purchase  shares
shall remain in the  participant's  account for the subsequent  Offering Period,
subject  to an  earlier  withdrawal  as  provided  in  paragraph  10.  During  a
participant's life time, a participant's  option to purchase shares hereunder is
exercisable only by him or her.

     9. Delivery.  Unless a participant  makes an election to delay the issuance
of Certificate  representing  purchased shares, as promptly as practicable after
each  Exercise  Date on which a purchase of shares  occurs,  the  Company  shall
arrange the  delivery to each  participant,  as  appropriate,  of a  certificate
representing  the  shares  purchased  upon  exercise  of his or  her  option.  A
participant  may make an  election to delay the  issuance of stock  certificates
representing  shares  purchased  under the Plan by giving  written notice to the
Company the form of Exhibit D to this Plan.  Any such  election  shall remain in
effect  until  it is  revoked  by the  participant  or,  if  earlier,  upon  the
termination of the participant's  Continuous Status as an Employee.  The Company
may limit the time or times during which participants may revoke such elections,
except that a participant shall  automatically  receive a certificate as soon as
practicable following termination of his or her Continuous Status as an Employee
and that participants shall be given the opportunity to revoke such elections at
least once each calendar year.



                                       57





     10. Withdrawal; Termination of Employment.

          (a) A  participant  may withdraw all but not less than all the payroll
deductions  credited to his or her  account and not yet used to exercise  his or
her option  under the Plan at any time by giving  written  notice to the Company
in the form  of  Exhibit  B to  this  Plan.  All  of the  participant's  payroll
deductions  credited  to his or her  account  will be  paid to such  participant
promptly after receipt of notice of withdrawal and such participant's option for
the Offering  Period will be  automatically  terminated,  and no further payroll
deductions  for the purchase of shares will be made during the Offering  Period.
If a participant withdraws from an Offering Period,  payroll deductions will not
resume at the beginning of the succeeding Offering Period unless the participant
delivers to the Company a new subscription agreement.

          (b) Upon  termination  of the  participant's  Continuous  Status as an
Employee  prior to the Exercise  Date for any reason,  including  retirement  or
death, the payroll deductions credited to such participant's  account during the
Offering Period but not yet used to exercise the option will be returned to such
participant  or,  in the case of his or her  death,  to the  person  or  persons
entitled  thereto  under  paragraph  14, and such  participant's  option will be
automatically terminated.

          (c) In the event an Employee  fails to remain in Continuous  Status as
an Employee  of the  Company  for at least  twenty (20) hours per week during an
Offering Period in which the Employee is a participant, he or she will be deemed
to have elected to withdraw from the Plan and the payroll deductions credited to
his or her account will be returned to such  participant and such  participant's
option terminated.

          (d) A  participant's  withdrawal from an Offering Period will not have
any effect upon his or her  eligibility to participate in any similar plan which
may hereafter be adopted by the Company or in succeeding  Offering Periods which
commence after the termination of the Offering Period from which the participant
withdraws.

     11.  Interest.  No interest  shall  accrue on the payroll  deductions  of a
participant in the Plan.

     12. Stock.

          (a) The maximum  number of shares of the Company's  Common Stock which
shall be made  available  for sale  under the Plan  shall be  2,350,000  shares,
subject to adjustment upon changes in  capitalization of the Company as provided
in paragraph  18. If on a given  Exercise Date the number of shares with respect
to which options are to be exercised exceeds the number of shares then available
under the Plan,  the  Company  shall make a pro rata  allocation  of the shares
remaining  available for purchase in as uniform a manner as shall be practicable
and as it shall determine to be equitable.

          (b) The  participant  will have no interest or voting  right in shares
covered by his option until such option has been exercised.


                                       58



          (c) Shares to be  delivered  to a  participant  under the Plan will be
registered in the name of the  participant or in the name of the participant and
his or her spouse.

     13.  Administration.  The Plan  shall be  administered  by the Board of the
Company  or a  committee  of members of the Board  appointed  by the Board.  The
administration,  interpretation  or  application of the Plan by the Board or its
committee shall be final, conclusive and binding upon all participants.  Members
of the Board who are eligible  Employees  are  permitted to  participate  in the
Plan.

     14. Designation of Beneficiary.

          (a) A participant may file a written  designation of a beneficiary who
is to receive any shares and cash, if any, from the participant's  account under
the Plan in the event of such participant's death subsequent to an Exercise Date
on which the option is exercised  but prior to delivery to such  participant  of
such shares and cash. In addition,  a participant may file a written designation
of a beneficiary who is to receive any cash from the participant's account under
the Plan in the  event of such  participant's  death  prior to  exercise  of the
option.

          (b) Such  designation of beneficiary may be changed by the participant
at any time by written notice. In the event of the death of a participant and in
the absence of a beneficiary  validly designated under the Plan who is living at
the time of such  participant's  death,  the Company  shall  deliver such shares
and/or cash to the executor or  administrator  of the estate of the participant,
or if no such executor or administrator  has been appointed (to the knowledge of
the Company),  the Company,  in its  discretion,  may deliver such shares and/or
cash  to the  spouse  or to any  one or  more  dependents  or  relatives  of the
participant,  or if no spouse,  dependent  or relative is known to the  Company,
then to such other person as the Company may designate.

     15. Transferability. Neither payroll deductions credited to a participant's
account nor any rights  with  regard to the  exercise of an option or to receive
shares  under  the Plan  may be  assigned,  transferred,  pledged  or  otherwise
disposed of in any way (other than by will, the laws of descent and distribution
or as provided in paragraph 14 hereof) by the  participant.  Any such attempt at
assignment,  transfer,  pledge or other  disposition  shall be  without  effect,
except that the Company may treat such act as an election to withdraw funds from
an Offering Period in accordance with paragraph 10.

     16. Use of Funds.  All payroll  deductions  received or held by the Company
under the Plan may be used by the Company  for any  corporate  purpose,  and the
Company shall not be obligated to segregate such payroll deductions.

     17. Reports. Individual accounts will be maintained for each participant in
the  Plan.  Statements  of  account  will be  given to  participating  Employees
semi-annually  promptly  following the Exercise Date,  which statements will set
forth the  amounts of payroll  deductions,  the per share  purchase  price,  the
number of shares purchased and the remaining cash balance, if any.



                                       59





     18.  Adjustments  Upon Changes in  Capitalization.  Subject to any required
action by the shareholders of the Company,  the number of shares of Common Stock
covered by each option under the Plan which has not yet been  exercised  and the
number of shares of Common Stock which have been  authorized  for issuance under
the  Plan  but  have  not  yet  been  placed  under  option  (collectively,  the
"Reserves"),  as well as the price per share of  Common  Stock  covered  by each
option under the Plan which has not yet been exercised, shall be proportionately
adjusted for any  increase or decrease in the number of issued  shares of Common
Stock  resulting  from a stock  split,  reverse  stock  split,  stock  dividend,
combination or  reclassification  of the Common Stock,  or any other increase or
decrease in the number of shares of Common  Stock  effected  without  receipt of
consideration  by  the  Company;  provided,  however,  that  conversion  of  any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of  consideration".  Such adjustment shall be made by the Board,
whose  determination  in that respect  shall be final,  binding and  conclusive.
Except as expressly  provided herein, no issue by the Company of shares of stock
of any class, or securities convertible into shares of stock of any class, shall
affect,  and no adjustment by reason  thereof shall be made with respect to, the
number or price of shares of Common Stock subject to an option.

     In the event of the proposed dissolution or liquidation of the Company, the
Offering  Period will terminate  immediately  prior to the  consummation of such
proposed  action,  unless  otherwise  provided  by the Board.  In the event of a
proposed sale of all or substantially  all of the assets of the Company,  or the
merger of the Company with or into  another  corporation,  any Purchase  Periods
then in progress  shall be shortened  by setting a new  Exercise  Date (the "New
Exercise  Date") and any Offering  Periods then in progress shall end on the New
Exercise  Date.  The New Exercise Date shall be before the date of the Company's
proposed sale or merger. The Board shall notify each participant in writing,  at
least ten (10) business days prior to the New Exercise  Date,  that the Exercise
Date for the participant's  option has been changed to the New Exercise Date and
that the  participant's  option  shall  be  exercised  automatically  on the New
Exercise Date,  unless prior to such date the participant has withdrawn from the
Offering Period as provided in Section 10 hereof.

     19. Amendment or Termination.  The Board of Directors of the Company may at
any time and for any reason  terminate or amend the Plan.  Except as provided in
paragraph  18,  no such  termination  can  affect  options  previously  granted,
provided that an Offering  Period may be terminated by the Board of Directors on
any Exercise Date if the Board determines that the termination of the Plan is in
the best  interests of the Company and its  shareholders.  Except as provided in
paragraph 18, no amendment may make any change in any option theretofore granted
which  adversely  affects the rights of any  participant.  In  addition,  to the
extent  necessary to comply with Section 423 of the Code (or any successor  rule
or provision  or any other  applicable  law or  regulation),  the Company  shall
obtain  shareholder  approval  in  such a  manner  and to  such a  degree  as so
required.

     20. Notices.  All notices or other  communications  by a participant to the
Company under or in  connection  with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location,  or by
the person, designated by the Company for the receipt thereof.



                                       60





     21.  Shareholder  Approval.  Continuance  of the Plan  shall be  subject to
approval by the shareholders of the Company within twelve months before or after
the date the Plan is adopted. Such shareholder approval shall be obtained in the
manner  and degree  required  under the  applicable  state and  federal  tax and
securities laws.

     22.  Conditions  Upon  Issuance of Shares.  Shares shall not be issued with
respect to an option  unless the  exercise of such option and the  issuance  and
delivery of such  shares  pursuant  thereto  shall  comply  with all  applicable
provisions  of law,  domestic or foreign,  including,  without  limitation,  the
Securities Act of 1933, as amended,  the Exchange Act, the rules and regulations
promulgated  thereunder,  and the  requirements of any stock exchange upon which
the shares may then be listed,  and shall be further  subject to the approval of
counsel for the Company with respect to such compliance.

     As a condition  to the  exercise of an option,  the Company may require the
person  exercising  such option to represent and warrant at the time of any such
exercise that the shares are being purchased only for investment and without any
present  intention  to sell or  distribute  such  shares  if, in the  opinion of
counsel  for  the  Company,  such a  representation  is  required  by any of the
aforementioned applicable provisions of law.

     23. Term of Plan. The Plan shall become effective upon the earlier to occur
of its adoption by the Board of Directors or its approval by the shareholders of
the  Company as  described  in para graph 21. It shall  continue in effect for a
term of twenty (20) years unless sooner terminated under paragraph 19.

         in  accordance   with  this Subscription Agreement and the Stock

3.       I understand that said payroll  deductions shall be accumulated for the
         purchase of shares of Common  Stock at the  applicable  purchase  price
         determined  in  accordance  with the Stock Purchase Plan. I understand
         that if I do not  withdraw  from an Offering  Period,  any  accumulated
         payroll deductions will be used to automatically exercise my option.

4.       I have  received a copy of the complete  "Trimble  Navigation  Employee
         Stock Purchase Plan." I understand that my  participation  in the Stock
         Purchase  Plan is in all  respects  subject to the terms of the Plan. I

         the Plan within 2 years after the Enrollment Date (the first day of the
         Offering  Period  during  which I  purchased  such  shares),  I will be
         treated for federal  income tax  purposes as having  received  ordinary
         income at the time of such disposition in an amount equal to the excess
         of the fair  market  value of the shares at the time such  shares  were
         delivered to me over the price which I paid for the shares.

   
                                       62


         I hereby  agree to notify the  Company in writing  within 30 days after

         understand  that I will be treated for federal  income tax  purposes as
         having received income only at the time of such  disposition,  and that
         such income  will be taxed as ordinary  income only to the extent of an
         amount  equal to the lesser of (1) the excess of the fair market  value
         of the shares at the time of such  disposition  over the purchase price
         which I paid for the shares under the option,  or (2) the excess of the
         fair market value of the shares over the option  price,  measured as if
         the option had been exercised on the Enrollment  Date. The remainder of
         the  gain,  if any,  recognized  on such  disposition  will be taxed as
         capital gain.

7.       I hereby agree to be bound by the terms of the Stock Purchase Plan. The
         effectiveness  of this  Subscription  Agreement  is  dependent  upon my
         eligibility to participate in the Stock Purchase Plan.
