                                  ABOUT TRIMBLE

     Trimble   Navigation   Limited,   a   California   corporation,   develops,
manufactures and distributes  innovative  products enabled by Global Positioning
System ("GPS") optical, laser and wireless communications technology. We provide
end-users  and  original  equipment  manufacturers  with  solutions  for diverse
applications  including  agriculture,  engineering and  construction,  fleet and
asset  management,  timing,  automobile  navigation and military.  Our principal
products,   which  utilize  substantial  amounts  of  proprietary  software  and
firmware,  are  integrated  systems  for  collecting,  analyzing  and  utilizing
position data in forms optimized for specific end-user applications.

                                  RISK FACTORS

     You should  carefully  consider  the  following  risk factors and all other
information  contained in this prospectus before participating in this offering.
Investing  in our common  stock  involves a high  degree of risk.  If any of the
following risks actually occur,  our business,  operating  results and financial
condition  could be  materially  harmed  and you might  lose all or part of your

Our Annual and Quarterly Performance May Fluctuate.

     Our operating  results have  fluctuated  and can be expected to continue to
fluctuate in the future on a quarterly  and annual basis as a result of a number
of factors, many of which are beyond our control. Results in any period could be
affected by changes in market  demand,  competitive  market  conditions,  market
acceptance  of  new or  existing  products,  fluctuations  in  foreign  currency
exchange  rates,  the  cost and  availability  of  components,  our  ability  to
manufacture and ship products,  the mix of our customer base and sales channels,
the mix of  products  sold,  our  ability  to expand  our  sales  and  marketing
organization  effectively,  our ability to attract and retain key  technical and
managerial  employees,  the timing of shipments of products under  contracts and
sale of licensing rights, and general global economic  conditions.  In addition,
demand for our  products  in any  quarter  or year may vary due to the  seasonal
buying  patterns  of our  customers  in the  agricultural  and  engineering  and
construction industries.  Due to the foregoing factors, our operating results in
one  or  more  future   periods  are  expected  to  be  subject  to  significant
fluctuations.  The price of our common stock could decline  substantially in the
event such  fluctuations  result in our  financial  performance  being below the
expectations of public market analysts and investors,  which are based primarily
on historical models that are not necessarily  accurate  representations  of the

Our Operating Results in Each Quarter May Not Accurately Reflect Business
Activity in Each Quarter.

     Due,  in part,  to the buying  patterns  of our  customers,  a  significant
portion of our quarterly  revenues  occurs from orders  received and immediately
shipped to  customers in the last few weeks and days of each  quarter,  although
our operating  expenses tend to remain  constant.  Engineering and  construction
purchases  tend to occur in early  spring,  and  governmental  agencies  tend to
utilize  funds  available  at the  end  of  the  government's  fiscal  year  for
additional purchases at the end of our third fiscal quarter in September of each
year.  Concentrations of orders sometimes also occur at the end of our other two
fiscal quarters. Additionally, a majority of our sales force earn commissions on
a quarterly basis,  which may cause  concentrations  of orders at the end of any
fiscal quarter.  If for any reason  expected sales are deferred,  orders are not
received, or shipments were to be delayed a few


days at the end of a quarter,  our operating  results and reported  earnings per
share for that quarter could be significantly impacted.

Our Inability to Accurately Predict Orders and Shipments May Affect Our Revenue,
Expenses and Earnings per Share.

     Because  we have  been  unable  in the  past to  predict  exactly  when our
customers will place orders and request shipments, we cannot accurately plan our
manufacturing requirements. As a result, if the orders and shipments differ from
what we predict,  we may incur additional expenses and build unneeded inventory,
which may require additional reserves.  Any significant change in our customers'
purchasing  patterns  could  have a  material  adverse  effect on our  operating
results and reported earnings per share for a particular quarter.

Our Gross Margin Is Subject to Fluctuation.

     Our gross margin is affected by a number of factors, including product mix,
product  pricing,  cost of  components,  foreign  currency  exchange  rates  and
manufacturing  costs.  For example,  since our Engineering and  Construction and
Geographic  Information  Systems  (GIS)  products  generally  have higher  gross
margins than our Component Technologies products,  absent other factors, a shift
in sales toward  Engineering and  Construction  and GIS products would lead to a
gross margin improvement.  On the other hand, if market conditions in the highly
competitive  Engineering and  Construction  and GIS market segments forced us to
lower unit prices, we would suffer a decline in gross margin unless we were able
to timely offset the price  reduction by a reduction in  production  costs or by
sales of other  products  with higher gross  margins.  A decline in gross margin
could have a material effect on our operating results.

We Are Dependent on a Sole Manufacturer for Our Products and on Sole Suppliers
of Critical Parts for Our Products.

     With the selection of Solectron  Corporation in August 1999 as an exclusive
manufacturing  partner for many of our GPS products previously  manufactured out
of our Sunnyvale facilities, we are substantially dependent upon a sole supplier
for the  manufacture  of our products.  Under the agreement with  Solectron,  we
provide to Solectron a twelve-month  product  forecast and place purchase orders
with  Solectron  sixty  calendar  days in advance of the  scheduled  delivery of
products to our customers.  Although  purchase  orders placed with Solectron are
cancelable,  the  terms of the  agreement  would  require  us to  purchase  from
Solectron  all material  inventory not  returnable or usable by other  Solectron
customers.  Accordingly, if we inaccurately forecast demand for our products, we
may be unable to obtain adequate  manufacturing  capacity from Solectron to meet
customers'  delivery  requirements or we may accumulate excess  inventories,  if
such inventories are not usable by other Solectron customers.

     In addition,  we rely on sole suppliers for a number of our critical ASICS.
We have experienced  shortages of supplies,  including ASICS, in the past. As an
example,  we were  affected by  industry-wide  shortages  of memory  devices and
electronic  components  that  reached  their  most  severe  impact  in the third
calendar  quarter of 2000.  Our current  reliance on sole or a limited  group of
suppliers involves several risks,  including a potential  inability to obtain an
adequate  supply of required  components and reduced  control over pricing.  Any
inability to obtain adequate deliveries


or any other  circumstance that would require us to seek alternative  sources of
supply or to manufacture such components  internally could  significantly  delay
our ability to ship our products,  which could damage relationships with current
and prospective  customers and could harm our reputation and brand,  which could
have a material adverse effect on our business.

Our Credit Agreement Contains Stringent Financial Covenants.

     Two of the financial  covenants in our Credit Agreement with ABN AMRO Bank,
N.V. and certain other banks,  dated as of July 14, 2000 as amended (the "Credit
Agreement"),  minimum  fixed charge  coverage and maximum  leverage  ratio,  are
extremely sensitive to changes in earnings before interest,  taxes, depreciation
and amortization  ("EBITDA").  In turn,  EBITDA is highly correlated to revenues
and cost  cutting.  Due to  uncertainties  associated  with the  downturn in the
worldwide economy, our future revenues by quarter are becoming increasingly more
difficult  to forecast and we have  recently  put in place  various cost cutting
measures,  including the consolidation of service functions and centers, closure
of redundant offices, consolidation of redundant product lines and reductions in
staff.  If revenues  should decline at a faster pace than the rate of these cost
cutting measures, on a quarter to quarter basis we may not be in compliance with
the two  above  mentioned  financial  covenants.  If we  default  on one or more
covenants, we will have to obtain either negotiated waivers or amendments to the
Credit  Agreement.  If we are unable to obtain such waivers or  amendments,  the
banks  would  have the  right  to  accelerate  the  payment  of our  outstanding
obligations  under the Credit  Agreement,  which  would have a material  adverse
effect on our  financial  condition and  viability as an operating  company.  In
addition,  a  default  under  one of  our  debt  instruments  may  also  trigger
cross-defaults  under our other debt instruments.  An event of default under any
debt instrument, if not cured or waived, could have a material adverse effect on

Our  Substantial  Indebtedness  Could  Materially  Restrict Our  Operations  and
Adversely Affect Our Financial Condition.

     We now have, and for the foreseeable  future will have, a significant level
of indebtedness. Our substantial indebtedness could:

     o    increase our  vulnerability  to general adverse  economic and industry

     o    limit  our   ability  to  fund   future   working   capital,   capital
          expenditures,  research and  development  and other general  corporate
          requirements, or to make certain investments that could benefit us;

     o    require  us to  dedicate  a  substantial  portion  of our cash flow to
          service interest and principal payments on our debt;

     o    limit our  flexibility  to react to  changes in our  business  and the
          industry in which we operate; and

     o    limit our ability to borrow additional funds.

We Face Competition in Our Markets.

     Our  markets  are highly  competitive  and we expect  that both  direct and
indirect  competition  will  increase  in the future.  Our  overall  competitive
position  depends  on a number of  factors  including  the  price,  quality  and
performance of our products,  the level of customer service,  the development of
new technology and our ability to participate in emerging  markets.  Within each


our markets,  we encounter direct  competition from other GPS, optical and laser
suppliers  and  competition  may  intensify  from  various  larger  domestic and
international  competitors  and new  market  entrants,  some of which may be our
current customers.  The competition in the future, may, in some cases, result in
price  reductions,  reduced margins or loss of market share,  any of which could
materially and adversely  affect our business,  operating  results and financial
condition.  We believe  that our ability to compete  successfully  in the future
against  existing and additional  competitors will depend largely on our ability
to execute our  strategy  to provide  systems and  products  with  significantly
differentiated  features compared to currently available products.  There can be
no assurance  that we will be able to implement this strategy  successfully,  or
that any such products will be competitive  with other  technologies or products
that  may be  developed  by our  competitors,  many of whom  have  significantly
greater  financial,  technical,   manufacturing,   marketing,  sales  and  other
resources  than we do. There can be no assurance that we will be able to compete
successfully against current or future competitors or that competitive pressures
cause us to lose  market  share or force us to engage in price  reductions  that
could have a material adverse effect on our business.

We May Encounter Problems Associated With International Operations and Sales.

     Our  customers  are located  throughout  the world.  Sales to  unaffiliated
customers in foreign locations represented  approximately 50% of our revenues in
our  fiscal  year 2001 and 52% in each of our  fiscal  years  2000 and 1999.  In
addition, we have significant international operations,  including manufacturing
facilities,  sales personnel and customer support operations.  Our international
sales operations include offices in Australia,  Canada, China, France,  Germany,
Great Britain, Japan, Mexico, New Zealand, Sweden, Russia, Singapore and others.
Our  international  manufacturing  facilities  are in Sweden  and  Germany.  Our
international  presence  exposes  us  to  risks  not  faced  by  wholly-domestic
companies.  Specifically,  we have experienced issues relating to integration of
foreign operations, greater difficulty in accounts receivable collection, longer
payment cycles and currency  fluctuations.  Additionally,  we face the following
risks, among others: unexpected changes in regulatory requirements;  tariffs and
other trade  barriers;  political,  legal and  economic  instability  in foreign
markets,  particularly in those markets in which we maintain  manufacturing  and
research  facilities;  difficulties  in staffing  and  management;  language and
cultural  barriers;  seasonal  reductions  in business  activities in the summer
months  in  Europe  and  some  other  countries;  and  potentially  adverse  tax
consequences.  Although we  implemented  a program to attempt to manage  foreign
exchange risks through hedging and other  strategies,  there can be no assurance
that  this  program  will  be  successful   and  that  currency   exchange  rate
fluctuations  will  not  have  a  material  adverse  effect  on our  results  of
operations.  In addition, in certain foreign markets, there may be reluctance to
purchase products based on GPS technology,  given the control of GPS by the U.S.


We Are Dependent on Proprietary Technology.

     Our  future  success  and  competitive   position  is  dependent  upon  our
proprietary  technology,  and we rely on patent,  trade  secret,  trademark  and
copyright law to protect our  intellectual  property.  There can be no assurance
that the patents owned or licensed by us will not be invalidated,  circumvented,
challenged,  or that the rights  granted  thereunder  will  provide  competitive
advantages to us or that any of our pending or future patent  applications  will
be issued  within  the  scope of the  claims  sought  by us,  if at all.  We are
currently defending two separate lawsuits for alleged patent  infringement,  one
alleging  infringement of a patent by some of our grade control  systems,  which
products  accounted  for  approximately  two percent (2%) of our revenues in our
fiscal year 2001, and another alleging  infringement by our surveying  products,
which products accounted for approximately  eleven percent (11%) of our revenues
in our fiscal year 2001.  In the event that in either or both of these suits our
products are held to be  infringing a valid patent,  we could be prevented  from
continuing  to sell these  products  and could be  required  to pay  substantial
damages, or, alternatively, enter into a royalty-bearing license agreement.

     There can be no assurance  that others will not develop  technologies  that
are similar or superior to our  technology,  duplicate our  technology or design
around the patents  owned by us. In addition,  effective  copyright,  patent and
trade  secret  protection  may be  unavailable,  limited or not  applied  for in
certain foreign countries.  There can be no assurance that the steps taken by us
to protect our technology will prevent the  misappropriation of such technology.
The value of our products relies  substantially  on our technical  innovation in
fields in which there are many current patent filings.  We recognize that as new
patents  are  issued or are  brought  to our  attention  by the  holders of such
patents, it may be necessary for us to withdraw products from the market, take a
license from such patent  holders,  or redesign our products.  We do not believe
any of our products  currently  infringe patents or other proprietary  rights of
third  parties,  but we cannot be certain  they do not do so. In  addition,  the
legal costs and engineering time required to safeguard  intellectual property or
to defend against  litigation could become a significant  expense of operations.
Such  events  could  have  a  material   adverse   effect  on  our  revenues  or

We Are Dependent on New Products.

     Our future revenue stream depends to a large degree on our ability to bring
new products to market on a timely basis.  We must continue to make  significant
investments  in  research  and  development  in order to continue to develop new
products,  enhance  existing  products  and achieve  market  acceptance  of such
products.  However,  there can be no assurance that  development  stage products
will be  successfully  completed  or, if  developed,  will  achieve  significant
customer  acceptance.  If we were  unable to  successfully  define,  develop and
introduce  competitive new products,  and enhance existing products,  our future
results of operations would be adversely affected. Development and manufacturing
schedules for technology products are difficult to predict,  and there can be no
assurance  that  we  will  achieve  timely  initial  customer  shipments  of new
products.  The  timely  availability  of these  products  in  volume  and  their
acceptance  by customers  are  important to our future  success.  A delay in new
product  introductions  could  have  a  significant  impact  on our  results  of
operations.  No  assurance  can be given that we will not incur  problems in the
future in innovating and introducing new products.


Our Stock Price May Be Volatile.

     Our  common  stock  has  experienced  and  can be  expected  to  experience
substantial  price  volatility  in response to actual or  anticipated  quarterly
variations in results of operations,  announcements of technological innovations
or new  products by us or our  competitors,  developments  related to patents or
other  intellectual  property  rights,  developments  in our  relationship  with
customers,  suppliers,  or strategic  partners  and other events or factors.  In
addition, any shortfall or changes in revenue, gross margins, earnings, or other
financial  results  from  analysts'  expectations  could  cause the price of our
common stock to fluctuate  significantly.  Additionally,  certain macro-economic
factors  such as changes in  interest  rates as well as market  climate  for the
high-technology  sector  could also have an impact on the  trading  price of our

We Face Risks of Entering Into and Maintaining Alliances.

     We believe that in certain  emerging markets our success will depend on our
ability to form and maintain  alliances with  established  system  providers and
industry  leaders.  Our  failure to form and  maintain  such  alliances,  or the
preemption  of  such  alliances  by  actions  of  other  competitors  or us will
adversely affect our ability to penetrate emerging markets. No assurances can be
given that we will not experience  problems from current or future  alliances or
that we will realize value from any such strategic alliances.

We Face Risks in Investing in and Integrating New Acquisitions.

     We are continuously evaluating external investments in technologies related
to our business,  and have made relatively small strategic equity investments in
a  number  of GPS  related  technology  companies.  Acquisitions  of  companies,
divisions of companies,  or products entail  numerous  risks,  including (i) the
potential  inability to successfully  integrate acquired operations and products
or to realize cost savings or other anticipated benefits from integration;  (ii)
diversion of  management's  attention;  (iii) loss of key  employees of acquired
operations;  and (iv) inability to recover strategic  investments in development
stage entities.  As a result of such  acquisitions,  we have significant  assets
that include  goodwill  and other  purchased  intangibles.  The testing of these
intangibles  under  established  accounting  guidelines for impairment  requires
significant  use of judgment  and  assumptions.  Changes in business  conditions
could require adjustments to the valuation of these assets. Any such problems in
integration or  adjustments  to the value of the assets  acquired could harm our
growth  strategy and have a material  adverse effect on our business,  financial
condition and compliance with debt covenants.

We Are Dependent on Key Customers.

     We currently enjoy strong  relationships with key customers.  An increasing
amount of our revenue is generated from large original  equipment  manufacturers
such as Siemens VDO Automotive,  Nortel,  Caterpillar,  CNH Global,  Bosch,  and
others.  A  reduction  or loss of  business  with these  customers  could have a
material  adverse  effect on our financial  condition and results of operations.
There can be no assurance that we will be able to continue to realize value from
these relationships in the future.


We Are Dependent on Retaining and  Attracting  Highly  Skilled  Development  and
Managerial Personnel.

     Our ability to maintain our competitive technological position will depend,
in a large  part,  on our  ability  to  attract,  motivate,  and  retain  highly
qualified  development  and  managerial  personnel.  Competition  for  qualified
employees in our industry and location is intense, and there can be no assurance
that we will be able to attract,  motivate and retain enough qualified employees
necessary for the future continued development of our business and products.

We Are Subject to the Impact of Governmental and Other Similar Certifications.

     We market  certain  products that are subject to  governmental  and similar
certifications  before  they can be sold.  For  example,  CE  certification  for
radiated  emissions is required  for most GPS  receiver and data  communications
products sold in the European Union. An inability to obtain such  certifications
in a timely manner could have an adverse effect on our operating results.  Also,
our products  that use  integrated  radio  communication  technology  require an
end-user to obtain licensing from the Federal Communications  Commission ("FCC")
for frequency-band usage. During the fourth quarter of 1998, the FCC temporarily
suspended  the  issuance of  licenses  for  certain of our  real-time  kinematic
products  because of  interference  with  certain  other users of similar  radio
frequencies. An inability or delay in obtaining such certifications or delays of
the FCC could  adversely  affect our  ability to bring our  products  to market,
which could harm our customer  relationships  and have a material adverse effect
on our business.

We Are  Dependent  on the  Availability  of  Allocated  Bands  Within  the Radio
Frequency Spectrum.

     Our GPS  technology  is dependent  on the use of the  Standard  Positioning
Service ("SPS")  provided by the U.S.  Government's  Global  Positioning  System
("GPS").  The GPS SPS  operates  in radio  frequency  bands  that  are  globally
allocated for radio navigation satellite services.  International allocations of
radio frequency are made by the International  Telecommunications Union ("ITU"),
a specialized  technical  agency of the United  Nations.  These  allocations are
further  governed by radio  regulations that have treaty status and which may be
subject to modification  every  two-three years by the World  Radiocommunication
Conference.  Any ITU reallocation of radio frequency bands,  including frequency
band  segmentation or sharing of spectrum,  may materially and adversely  affect
the utility and  reliability  of our  products,  which would,  in turn,  cause a
material adverse effect on our operating results. Many of our products use other
radio frequency  bands,  together with the GPS signal,  to provide  enhanced GPS
capabilities, such as real-time kinematic precision. The continuing availability
of these non-GPS radio frequencies is essential to provide enhanced GPS products
to our precision survey markets.  Any regulatory changes in spectrum  allocation
or in allowable  operating  conditions may  materially and adversely  affect the
utility and reliability of our products,  which would, in turn, cause a material
adverse effect on our operating  results.  In addition,  unwanted emissions from
mobile satellite  services and other equipment  operating in adjacent  frequency
bands or  inband  from  licensed  and  unlicensed  devices  may  materially  and
adversely affect the utility and reliability of our products, which could result
in a material  adverse  effect on our  operating  results.  The FCC  continually
receives proposals for novel  technologies and services,  such as ultra-wideband
technologies, which may seek to operate in, or across, the radio frequency bands
currently  used by the  GPS  SPS  and  other  public  safety  services.  Adverse
decisions by the FCC that result in harmful


interference to the delivery of the GPS SPS and other radio  frequency  spectrum
also used in our products may  materially  and adversely  affect the utility and
reliability of our products,  which could result in a material adverse effect on
our business and financial condition.

We Are Subject to the Adverse Impact of Radio Frequency Congestion.

     We have certain real-time kinematic products, such as our Land Survey 5700,
that use  integrated  radio  communication  technology  that requires  access to
available radio frequencies  allocated by the FCC. In addition,  access to these
frequencies by state agencies is under management by state radio  communications
coordinators.  Some  bands  are  experiencing  congestion  that  excludes  their
availability for access by state agencies in some states, including the state of
California.  An inability to obtain access to these radio frequencies could have
an adverse effect on our operating results.

We Are Reliant on the GPS Satellite Network.

     The GPS satellites and their ground support systems are complex  electronic
systems subject to electronic and mechanical failures and possible sabotage. The
satellites were  originally  designed to have lives of 7.5 years and are subject
to damage by the hostile space  environment in which they operate.  However,  of
the current  deployment  of 28  satellites  in place,  some have already been in
place for 12 years. To repair damaged or malfunctioning  satellites is currently
not economically  feasible. If a significant number of satellites were to become
inoperable, there could be a substantial delay before they are replaced with new
satellites.  A reduction in the number of operating  satellites would impair the
current  utility of the GPS system  and the  growth of  current  and  additional
market  opportunities.  In  addition,  there can be no  assurance  that the U.S.
Government  will  remain  committed  to the  operation  and  maintenance  of GPS
satellites over a long period,  or that the policies of the U.S.  Government for
the  use  of  GPS  without  charge  will  remain  unchanged.   However,  a  1996
Presidential  Decision  Directive  marks the first time in the  evolution of GPS
that access for civilian use free of direct user fees is specifically recognized
and supported by Presidential policy. In addition,  Presidential policy has been
complemented  by  corresponding   legislation,   signed  into  law.  Because  of
ever-increasing  commercial  applications of GPS, other U.S. Government agencies
may become  involved in the  administration  or the regulation of the use of GPS
signals.  Any of the foregoing factors could affect the willingness of buyers of
our products to select GPS-based  systems instead of products based on competing
technologies.  Any resulting change in market demand for GPS products could have
a material  adverse  effect on our  financial  results.  For  example,  European
governments  have  expressed  interest  in  building  an  independent  satellite
navigation system, known as Galileo. Depending on the as yet undetermined design
and operation of this system,  there may be  interference to the delivery of the
GPS SPS which may materially and adversely affect the utility and reliability of
our products,  which could result in a material  adverse  effect on our business
and operating results.


We Are Reliant on a Continuous Power Supply.

     California recently experienced an energy crisis that threatened to disrupt
our operations and resulted in increased expenses for our California facilities.
In the event of an acute power  shortage,  that is, when power  reserves for the
State of California fall below certain critical  levels,  California has on some
occasions  implemented,  and may in the future  continue to  implement,  rolling
blackouts  throughout  the  state.  We  currently  do not have  adequate  backup
generators  or  alternate  sources of power in the event of a blackout,  and our
current  insurance does not provide coverage for any damages we or our customers
may suffer as a result of any  interruption  in our power  supply.  If blackouts
interrupt our power supply or Solectron's  power supply, we would be temporarily
unable  to  continue   operations  at  our  California   facilities.   Any  such
interruption  in  our  ability  to  continue  operations  at our  facilities  or
Solectron's  ability to manufacture  product at its facilities  could damage our
reputation,  harm our  ability to retain  existing  customers  and to obtain new
customers,  and could result in lost revenue,  any of which could  substantially
harm our business and results of operations.

We Must Carefully Manage Our Future Growth.

     Any continued  growth in our sales or any continued  expansion in the scope
of our operations could strain our current management, financial,  manufacturing
and other  resources  and may require us to  implement  and improve a variety of
operating, financial and other systems, procedures and controls. Specifically we
have  experienced  strain in our financial  and order  management  system,  as a
result of our  acquisitions.  While we plan to  expand  our  sales,  accounting,
manufacturing, and other information systems to meet these challenges, there can
be no assurance  that these  efforts will  succeed,  or that any existing or new
systems  over time,  procedures  or  controls  will be  adequate  to support our
operations  or that our  systems,  procedures  and  controls  will be  designed,
implemented or improved in a cost  effective and timely  manner.  Any failure to
implement,  improve and expand such systems, procedures and controls in a timely
and efficient  manner could harm our growth  strategy and  adversely  affect our
financial condition and ability to achieve our business objectives.

Provisions  in Our  Preferred  Share  Rights  Agreement  May Have  Anti-Takeover

     Our  preferred  share rights  agreement  gives our board of  directors  and
shareholders the ability to dilute the ownership of any person acquiring fifteen
percent (15%) or more of our common stock,  thereby  potentially making any such
acquisition  impractical for an acquirer.  The existence of this preferred share
rights  agreement  could delay,  defer or prevent a change of control of us in a
transaction not approved by our board of directors.

                                 USE OF PROCEEDS

     The selling  shareholders  will receive all of the proceeds from the shares
to be sold in this offering.

                              SELLING SHAREHOLDERS

     The shares of common stock being registered in this registration  statement
and the warrant  exercisable for shares of our common stock being  registered in
this registration  statement were originally  offered in three unrelated private
placement equity offerings.


Consultant Shares

     This prospectus  covers,  in part, the resale of shares of our common stock
issued  to Global  Accelerator  LLC.  We issued  these  shares in  exchange  for
consulting services rendered to us, pursuant to the terms of our agreement dated
September 11, 2000 with 54th Street  Partners (of which Global  Accelerator is a
division). The shares were issued to Global Accelerator on September 26, 2001.

Acquisition Agreement Shares

     This prospectus  covers,  in part, the resale of shares of our common stock
which we have agreed to issue to Dr. Herbert Landau  pursuant to the terms of an
acquisition agreement dated April 17, 2002 between Dr. Landau and our subsidiary
Trimble Holdings Gmbh, a German company. Pursuant to the terms of the agreement,
we will issue  87,335  shares of our  common  stock to Dr.  Landau  and  Trimble
Holdings  Gmbh will pay Euro  310,412.32  to Dr. Landau in exchange for the sale
and  transfer  to Trimble  Holdings  Gmbh of Dr.  Landau's  shares and rights to
profits in a German  company of which Trimble  Holdings  Gmbh is a  shareholder.
There are no conditions  within our control or the control of the purchaser that
must be  satisfied  in order to  consummate  the sale of such  shares.  The only
condition to funding is that this registration  statement is declared effective.
The number of shares to be  purchased by Dr.  Landau and the  purchase  price of
such shares were fixed prior to filing this registration statement.

Warrant Shares

     This  prospectus  covers,  in remaining  part,  the resale of shares of our
common  stock  issuable  to  Spectra  Physics  Holdings  USA,  Inc.,  a Delaware
corporation,  upon exercise of a warrant issued to Spectra on April 12, 2002, in
accordance with its terms.

     Spectra  is an  indirect  subsidiary  of  Thermo  Electron  Corporation,  a
Delaware  corporation.  In July 2000, we acquired Spectra Precision,  a group of
wholly-owned  businesses,  from Thermo Electron. As part of the acquisition,  we
issued Spectra a subordinated seller note in the amount of $80 million. On March
20, 2002, we renegotiated the terms of the subordinated  note. Under the revised
agreement,  the  maturity of the note was extended  until July 14, 2004,  at the
current  interest rate of  approximately  10.4% per year. In connection with the
amendment,  we issued to  Spectra a warrant  to  purchase  a maximum  of 376,233
shares of our  common  stock,  exercisable  over a set time  period.  Initially,
Spectra will have the option to purchase  200,000  shares of common stock over a
five-year  period at an exercise price of $15.11.  Subsequently,  on a quarterly
basis  beginning on July 14, 2002,  Spectra will have the option to purchase 250
shares  of  common  stock  for  every  $1  million  of  principal  and  interest
outstanding  until the note is paid off in full.  These  shares can be purchased
for a period of five years from each quarterly  anniversary  date at an exercise
price equal to the average of the closing  sale prices for a share of our common
stock  as  quoted  on the  Nasdaq  National  Market  for the five  trading  days
immediately  preceding  and ending on the  trading  day that is one  trading day
prior to each such quarterly  anniversary  date. The number of shares subject to
the  warrant  and the  exercise  price  of such  warrant  are  both  subject  to
adjustment  as  provided  in the  warrant.  The total  number  of shares  issued
pursuant to this warrant shall not exceed 376,233.


     Some of our  affiliates  have held  positions  with  affiliates  of Spectra
Physics Holdings USA. Prior to joining us in March 1999, Steven W. Berglund, our
President,  Chief  Executive  Officer and a  director,  served as  President  of
Spectra Precision, Inc., a Delaware corporation, which we acquired in connection
with the  Spectra  Precision  Group.  Karl G.  Ramstrom,  prior to joining us in
August 2000 as Senior Vice President and General  Manager of our Engineering and
Construction Division, served as President of the Spectra Precision Group.

     days of April 18, 2002.

     calculating  this amount for each  holder,  we treated as  outstanding  the
     number of shares of common stock  issuable upon exercise of all options and

     We  prepared  this table  based on the  information  supplied  to us by the
selling shareholders named in the table.

     The  selling  shareholders  listed  in the  above  table  may have  sold or
transferred,  in transactions  exempt from the registration  requirements of the
Securities  Act,  some or all of their shares or their warrant since the date on
which the  information  in the above table is presented.  Information  about the
selling shareholders may change over time.

     Because  the  selling  shareholders  may offer all or some of their  common
stock from time to time, we cannot estimate the amount of common stock that will
be held by the  selling  shareholders  upon the  termination  of any  particular
offering. See "Plan of Distribution."


                              PLAN OF DISTRIBUTION

     We will not  receive any of the  proceeds  of the sale of the common  stock
offered by this prospectus.  The selling shareholders and any of their pledgees,
assignees and successors-in-interest named in the Registration Statement on Form
S-3 may,  from time to time,  sell any or all of their shares of common stock on
any stock exchange, market or trading facility on which the shares are traded or
in private  transactions.  These sales may be at fixed or negotiated prices. The
selling  shareholders  may use any one or  more of the  following  methods  when
selling shares:

     o    ordinary   brokerage   transactions  and  transactions  in  which  the
          broker-dealer solicits purchasers;

     o    block  trades  in which the  broker-dealer  will  attempt  to sell the
          shares as agent but may  position and resell a portion of the block as
          principal to facilitate the transaction;

     o    purchases  by  a   broker-dealer   as  principal  and  resale  by  the
          broker-dealer for its account,  which may include a firm commitment or
          best efforts underwritten offering;

     o    an  exchange   distribution  in  accordance  with  the  rules  of  the
          applicable exchange;

     o    privately negotiated transactions;

     o    short sales;

     o    broker-dealers  may  agree  with the  selling  shareholders  to sell a
          specified number of such shares at a stipulated price per share;

     o    a combination of any such methods of sale; and

     o    any other method permitted pursuant to applicable law.

     The  selling  shareholders  may also sell  shares  under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

     The selling  shareholders  may also engage in short sales  against the box,
puts and calls and other  transactions  in our  securities or derivatives of our
securities and may sell or deliver shares in connection  with these trades.  The
selling  shareholders  may pledge their shares to their brokers under the margin
provisions of customer agreements. If a selling shareholder defaults on a margin
loan, the broker may, from time to time, offer and sell the pledged shares.

     Broker-dealers  engaged by the selling  shareholders  may arrange for other
brokers-dealers to participate in sales.  Broker-dealers may receive commissions
or discounts from the selling  shareholders  (or, if any  broker-dealer  acts as
agent  for the  purchaser  of  shares,  from the  purchaser)  in  amounts  to be
negotiated.  The  selling  shareholders  do not  expect  these  commissions  and
discounts to exceed what is customary in the types of transactions involved.

     The selling shareholders and any broker-dealers or agents that are involved
in selling the shares may be deemed to be  "underwriters"  within the meaning of
the Securities Act in connection with such sales. In such event, any commissions
received  by such  broker-dealers  or agents and any profit on the resale of the
shares  purchased  by them  may be  deemed  to be  underwriting  commissions  or
discounts under the Securities Act.


     We are required to pay all fees and expenses  incident to the  registration
of the shares for resale by Spectra. We have agreed to indemnify Spectra against
certain losses, claims, damages and liabilities, including liabilities under the
Securities  Act, and Spectra has agreed to indemnify us against  certain losses,
claims, damages and liabilities, including liabilities under the Securities Act.
