          Trimble Announces Fiscal Fourth Quarter and Year-End Results


SUNNYVALE,  Calif.,  Jan.  30, 2002 - Trimble  (Nasdaq:  TRMB)  today  announced
results for the fiscal  fourth  quarter and year ended  December 28,  2001.  The
Company  reported  fourth  quarter  revenues of $106.4  million,  with  adjusted
earnings  per share (EPS) of $0.02.  Adjusted  EPS  excludes  any  one-time  and
acquisition   related   charges,   being   primarily   goodwill  and  intangible
amortization costs from acquisitions,  and restructuring  charges related to the
Company's  cost-cutting  measures  that would be included  when  reporting  on a
Generally Accepted  Accounting  Principles (GAAP) basis. GAAP EPS for the fourth
quarter and entire fiscal 2001 were ($0.26) and ($0.93), respectively.

For fiscal year 2001,  revenue and adjusted  EPS were $475.3  million and $0.36,
respectively.  This compares to pro-forma (reflecting the acquisition of Spectra
Precision  Group  and  Tripod  Data  Systems,  and the  sales  of the  Company's
commercial and business airline  operations)  revenue of $498.2 and adjusted EPS
of $1.22 in fiscal 2000.


The  Company   reported   earnings  before  interest,   tax,   depreciation  and
amortization  (EBITDA),  before  restructuring  charges, of $10.1 million in the
fourth fiscal quarter, and $45.2 million for fiscal 2001.

"Within a challenging  economy,  Trimble continued to strengthen its competitive
and financial  position in 2001," said Steven W. Berglund,  president and CEO of
Trimble.  "Early in 2001, we saw signs of an economic  downturn and  implemented
new cost cutting  initiatives  in addition to those  already in place as part of
the Spectra  Precision  acquisition.  These early actions helped bring our fixed
cost structure in line with what we believed to be  recessionary  conditions and
allowed us to remain  profitable on an adjusted  basis,  as the economy  further
declined. We took further actions over the past 6 weeks by raising approximately
$46 million in a private equity placement.  The proceeds were used to reduce our
overall debt level and future interest expense.  In addition to paying down debt
with the proceeds of the private equity deal, during the fourth quarter, we also
paid an additional $29 million using cash from  operations.  The result of these
actions was the lowering of our break-even point."

"At the same time we were cutting costs, we selectively  invested in initiatives
that we believe will create growth  including the  introduction of new products,
the expansion of our  distribution  channels and new alliances.  Of significance
was the creation of Trimble Mobile Solutions (TMS). TMS is intended to enable us
to build upon our existing fleet  management  hardware  offerings to offer fully
bundled solutions to the mobile security,  telematics,  workforce management and
targeted fleet management  markets. We are currently adding capabilities in this
market and expect to begin to see tangible results in the second half of 2002."

Business Segment Detail for Fiscal Fourth Quarter and Year End 2001

Engineering and Construction revenues were $69.1 million versus $74.5 million in
the year ago quarter. For the year,  Engineering and Construction  revenues were
$303.9 million, or 64 percent of consolidated revenue, versus $310.4 million, or
62 percent of revenue in fiscal 2000, on a pro forma basis.


Fleet and Asset  Management  revenues  were $13.7  million as  compared to $16.9
million in the year ago quarter.  For the year,  revenues were $57.7 million, or
12 percent of consolidated  revenue, as compared to $65.1 million, or 13 percent
of revenue in 2000.

Revenues from the Components Technologies segment were $12.7 million as compared
to $18.4  million in the year ago  quarter.  For the year,  revenues  were $58.1
million,  or 12 percent  of  consolidated  revenue  versus  $60.2  million or 12
percent of revenue in 2000.

Agriculture  revenues  for the fourth  quarter  were $4.3  million  versus  $7.9
million in the year ago quarter.  For the year, revenues were $24.6 million or 5
percent of consolidated revenue, versus $34.1 million or 7 percent of revenue in
2000, on a pro forma basis.

Revenues from  Portfolio  Technologies  were $6.6 million for the fourth quarter
versus $6.4m in the year ago quarter. For the year, revenues were $31 million or
7% of consolidated revenue,  versus $28.4 million or 6% of revenue in 2000, on a
pro forma basis.

Looking Ahead

Berglund  concluded,  "We remain  cautious  and still  believe the economy  will
continue to be a challenge in 2002.  However,  we continue to build capabilities
that will serve our customers and to take strategic  actions designed to further
strengthen  Trimble's  market  position.  These  actions  include new  products,
alliances  with  industry  leaders,  improved  systems  and  development  of our
distribution  channels.  When customer  buying  behavior and the overall economy
improve,  we believe that these  actions,  combined with our cost cutting,  will
position Trimble to demonstrate improved financial performance."

The Company expects  revenues for its first fiscal quarter ending March 29, 2002
to be  approximately  $104 to $106  million,  with  adjusted EPS in a range from
breakeven  to $0.03.  While the Company has limited  visibility  into the entire
fiscal year 2002,  it expects to achieve an increase in revenue and adjusted EPS
for the second fiscal quarter due to the normal  seasonality of the  engineering
and construction market.
