              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - Basis of Presentation:

The  condensed  consolidated  financial  statements  for the three and six month
periods ended June 30, 1997, and 1996 presented in this Quarterly Report on Form
10-Q are  unaudited.  The balance  sheet at December 31, 1996,  has been derived
from the audited  financial  statements at that date but does not include all of
the  information  and  footnotes  required  by  generally  accepted   accounting
principles  for complete  financial  statements.  In the opinion of  management,
these  statements  include all adjustments  (consisting only of normal recurring
adjustments)  necessary  for a fair  statement  of the  results  for the interim
periods presented.  The condensed  consolidated  financial  statements should be
read in conjunction with the audited consolidated financial statements and notes
thereto  included in the Company's  Annual Report to  Shareholders  for the year
ended December 31, 1996.

The results of  operations  for the three month and six month periods ended June
30, 1997 are not necessarily  indicative of the results that may be expected for
the year ending December 31, 1997.

NOTE 3 - New Accounting Standards:

Effective January 1, 1997, the Company adopted Statement of Financial Accounting
Standards  No. 125 ("SFAS  125"),  "Accounting  for  Transfers  and Servicing of
Financial  Assets and  Extinguishments  of  Liabilities."  At June 30, 1997, the
Company was  contingently  liable to a Japanese  bank for  $356,000 at month end
exchange rates arising from customers'  notes  receivable which the Company sold
with recourse to the bank. In accordance with SFAS 125, the Company has recorded
this amount as a liability.


                                       6


* In February 1997, the Financial  Accounting  Standards Board issued  Statement
No. 128,  "Earnings Per Share",  which is required to be adopted on December 31,
1997. At that time, the Company will be required to change the method  currently
used to compute  earnings per share and to restate all prior periods.  Under the
new requirements for calculating primary earnings per share, the dilutive effect
of  stock  options  will  be  excluded.  The  impact  of  Statement  128  on the
calculation  of primary and fully  diluted  earnings  per share for the quarters
reported is not expected to be material.


NOTE 4 - Contingencies:

Shareholder Litigation

On December 6, 1995, two  shareholders  filed a class action lawsuit against the
Company and certain  directors  and officers of the Company.  Subsequent to that
date,  additional lawsuits were filed by other  shareholders.  The lawsuits were
subsequently  amended and  consolidated  into one  complaint  which was filed on
April 5, 1996. The amended consolidated complaint sought to bring an action as a
class action  consisting  of all persons who  purchased  the common stock of the
Company during the period April 18, 1995,  through  December 5, 1995 (the "Class
Period").  The  plaintiffs  alleged  that the  defendants  sought to induce  the
members of the Class to purchase  the  Company's  common  stock during the Class
Period at  artificially  inflated  prices.  The  plaintiffs  seek  recissory  or
compensatory  damages with interest  thereon,  as well as reasonable  attorneys'
fees and extraordinary  equitable and/or injunctive  relief. The Company filed a
motion to dismiss,  which was heard by the Court on August 16,  1996.  The court
rejected  the  plaintiffs'  lawsuit,  but allowed  thirty  days to resubmit  its
complaint.  On September 24, 1996, the plaintiffs filed an amended complaint. On
April 28, 1997,  the Court  granted in part,  and denied in part,  the Company's
motion to dismiss.  The Court further  granted the  plaintiffs  leave to replead
certain  dismissed claims. On June 19, 1997 the plaintiffs filed a third amended
and  consolidated  complaint.  The Company  has filed a motion to  dismiss.  The
Company  does not  believe  that it is  possible  to predict the outcome of this
litigation.

Other Litigation

* In October 1995, an employee who was terminated by the Company in 1992 filed a
Complaint  against  the  Company,  alleging  that his  incentive  stock  options
continued  to  vest  subsequent  to  his   termination.   He  seeks  damages  of
approximately  $1,000,000.  The Company has filed a general  denial in answer to
the Complaint, and a trial date has been set for September 15, 1997. The Company
does not believe that the Complaint will be successful.

In September 1996, the British Technology Group ("BTG") brought suit for alleged
infringement  of its  RE.34,004  patent.  BTG has also  brought suit against two
other  defendants  over the same patent.  Discovery  is underway,  and a Markman
hearing is scheduled in the Eastern  District of  Pennsylvania  for September 9,
1997. Trial is set for January 8, 1998. The Company believes the suit is without
merit and intends to defend itself vigorously.


                                       7



Note 5 - Line of Credit

In August 1995, the Company entered into a $30,000,000  unsecured line of credit
agreement  with two banks which  expired in July 1997.  In July 1997 the Company
has received an amendment to extend the line of credit to September 1, 1997. The
agreement enables the Company to borrow up to $30,000,000  provided that certain
financial and other  covenants are met. The agreement  provides for payment of a
commitment fee of 0.5% for the unused portion of the line of credit.  Borrowings
bear  interest at the higher of (i) one of the bank's annual prime rate and (ii)
the federal funds rate plus 0.5%.  To date,  no borrowings  have been made under
the line of credit.  Under the current line of credit the Company is  restricted
from paying  dividends.  The Company intends to obtain another line of credit on
similar terms on September 1, 1997.


Note 6 - Subsequent Events:

On July 25,  1997,  the Company  made a bridge loan for $1.5  million to Proshot
Golf, Inc, a minority  investee of the Company,  at prime plus 1.5%. The loan is
due on or before  February  25, 1998 and is secured  entirely by an  irrevocable
stand-by  letter  of  credit  with a  commercial  bank  having  the  Company  as
beneficiary and Proshot as account party.

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS



RESULTS OF OPERATIONS


Revenues

Revenues for the three month and six month  periods  ended June 30,  1997,  were
$68,944,000 and  $129,495,000 as compared with  $58,602,000 and  $115,324,000 in
the corresponding 1996 periods.The table below breaks out the Company's revenues

Commercial Systems

Commercial Systems revenues for the three month and six month periods ended June
30, 1997  increased  in total over the prior year period,  however,  the Company
experienced  a decrease in the Land Survey  vertical  market as compared to June
30, 1997. However,  the Company believes that it has maintained its market share
worldwide.

The  decreases in Land Survey sales in the second  quarter of 1997,  compared to
the second  quarter of 1996,  are due in part to the continued  slow down of the
European and Japanese economies.

The  decrease  in Land  Survey  sales were  offset by an increase in the overall
Commercial  Systems' revenues for the second quarter of 1997, as compared to the
second  quarter of 1996,  which occurred  primarily in the Precise  Positioning,
GIS, and Tracking vertical markets.

Tracking and  Communications  revenues have  increased in the second  quarter of
1997 compared to the second  quarter of 1996 due to the  resumption of shipments
in March 1997 to American Mobile Satellite  Corporation  (AMSC), a company based
in Reston,  Virginia,  that  provides a variety of voice and data  services  via
satellite. The shipments were originally discontinued late in the fourth quarter
of 1995 at the request of AMSC,  in part due to delays in AMSC's  completion  of
software. On February 20, 1997, an agreement was signed between Trimble and AMSC
to resume shipments of Trimble's  Galaxy/GPS  terminals at the rate of 500 units
per month,  beginning  in March 1997.  


                                       9



Approximately  1,750 and 2,000  units were  shipped  in the three  month and six
month periods ending June 30, 1997, respectively.

Software and Component Technologies

Software and Component  Technologies  revenues increased for the three month and
six month  periods  ended June 30,  1997,  as  compared  with the  corresponding
periods for 1996 due primarily to a $2.2 million technology license from Pioneer
Electronic  Corporation  in  connection  with the expansion of the original 1992
license for in-car navigation technology recorded in the 1997 periods.

Aerospace

* Sales of  Aerospace  products  increased  for the three and six month  periods
ending June 30, 1997,  compared to the same periods in 1996 primarily due to the
increased  sales of the HT 9100,  Honeywell  Trimble  product line.  The Company
considers  its  Aerospace  products  to be a long term  growth  opportunity.  It
believes  that  success in this area will be  dependent  upon the success of the
current strategic alliance with Honeywell.

* Military sales increased  slightly in the second quarter of 1997,  compared to
the second  quarter of 1996.  Military  sales are highly  dependent on contracts
that are subject to government approval and are, therefore, expected to continue
to fluctuate from period to period.  The Company believes that  opportunities in
this market  have been  substantially  reduced by  cutbacks in U.S.  and foreign
military spending.

Revenue outside the US

* Sales to  unaffiliated  customers  in  locations  outside  the U.S.  comprised
approximately  45% and 48% of  revenue in the first six months of 1997 and 1996,
respectively. During the first six months of 1997, the Company experienced lower
revenues in Europe in many  product  lines,  and in Japan  primarily  related to
surveying  products.  The Company anticipates that export revenue and sales made
by its subsidiaries in locations outside the U.S. will continue to account for a
significant portion of its revenue and, therefore, the Company is subject to the
risks  inherent  in these  sales,  including  unexpected  changes in  regulatory
requirements,  exchange rates, governmental approval, tariffs or other barriers.
Even  though the U.S.  Government  announced  on March 29,  1996,  that it would
support and maintain the GPS system,  as well as eliminate  the use of Selective
Availability  (S/A) (a method of degrading GPS  accuracy),  customers in certain
foreign  markets may be reluctant to purchase  products  based on GPS technology
given the  control  of GPS by the U.S.  Government.  The  Company's  results  of
operations could be adversely affected if the Company were unable to continue to
generate significant sales in locations outside the U.S.


Gross Margin

* Gross margin varies on a quarterly basis due to a number of factors, including
product mix,  technology  license fees,  domestic  versus  international  sales,
customer type, the effects of production volumes and fixed  manufacturing  costs
on unit  product  costs  and new  product  start-up  costs.  Gross  margin  as a


                                       10


percentage  of total  product  revenue  was 53% for both the three month and six
month periods  ended June 30, 1997,  as compared  with 54% in the  corresponding
1996  periods.  The 1997  margins have been  enhanced by the positive  impact of
non-product  revenues  recognized  from  Pioneer  of $2.2  million in the second
quarter of 1997. Although,  the Company has recorded similar non-recurring items
in the past,  including $2,080,000 in the first six months of 1996, there can be
no assurance that similar items will recur in the future. The lower gross margin
percentage for the 1997 three month and six month periods,  primarily  reflect a
shift in product mix from higher margin Commercial Systems sales to lower margin
Avionics  and OEM  sales  and  decreases  in the  margins  obtained  on sales of
Commercial  Systems products.  There can be no assurance that these margins will
be sustained because of mix changes within and among the business units,  market
pressures on unit selling prices,  fluctuations in unit manufacturing  costs and
other factors.  While Commercial Systems products have the highest gross margins
of all the Company's  products,  those margins have decreased  primarily because
the Company has reduced prices on these products in response to competition. The
Company expects  competition to increase in its Commercial  Systems markets and,
therefore, it is likely that further price erosion will occur, with consequently
lower gross margin percentages in the future.

* The Company  also  expects  that a higher  percentage  of its  business in the
future  will be  conducted  through  alliances  with  strategic  partners,  e.g.
Honeywell,  Caterpillar,  and  Case.  As a  result  of  volume  pricing  and the
assumption of certain operating costs in connection with such partners,  margins
are likely to be lower than sales directly to end-users.

Operating Expenses

The  following  table shows  operating  expenses for the periods  indicated  and
should be read in conjunction with the narrative descriptions of those operating

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



Research and Development

Research  and  development  expenses  increased in the three month and six month
periods ended June 30, 1997, as compared  with the  corresponding  1996 periods.
The higher  research and  development  expense in the 1997 periods are due to an
increase in personnel and the related  expenses  which  accompany an increase in
the number of employees.  The increase in research and development  personnel is
part of the Company's continuing focus on developing future products.

* The Company  expects  that a  significant  portion of its future  revenues and
operating  income  will  continue to be derived  from sales of newly  introduced


                                       11


products.  Consequently,  the Company's  future  success  depends in part on its
ability to continue to advance product technology and to develop and manufacture
new  competitive  products  with high  gross  profit  margins.  Development  and
manufacturing  schedules for technology  products are difficult to predict,  and
there can be no assurance that the Company 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 the future  success of the
Company.  In  addition,  certain  of  the  Company's  products  are  subject  to
governmental  and similar  certifications  before they can be sold. For example,
FAA certification is required for all aviation  products.  An inability or delay
in obtaining such  certifications  could have an adverse effect on the Company's
operating results.

Sales and Marketing

The  decreased  sales and  marketing  expenses for the three month and six month
periods ended June 30, 1997, as compared with the corresponding  periods in 1996
is due primarily to a reduction in headcount and related expenses resulting from
the  Company's  restructuring  in  September  1996.  In  addition,  the  Company
experienced  decreases in  advertising  and  promotional  items related to lower
costs for the annual report and lower media development costs.

The  Company's  future  growth  will  depend  upon the  timely  development  and
continued  viability of the markets in which the Company currently  competes and
upon the  Company's  ability to continue to identify and exploit new markets for
its products. In addition, the Company has encountered  significant  competition
in selected  markets,  and the Company expects such  competition to intensify as
the market for GPS applications  receives  acceptance.  Several of the Company's
competitors  are  major  corporations  with  substantially   greater  financial,
technical,  marketing and  manufacturing  resources.  Increased  competition  is
likely to result in reduced  market share and in price  reductions  of GPS-based
products, which could adversely affect the Company's revenues and profitability.

General and Administrative

The decrease in general and  administrative  expense for the three month and six
month periods ended June 30, 1997,  as compared with the  corresponding  periods
for 1996,  primarily  reflects  lower  legal  expenses  as a result  of  reduced
litigation.

Income Taxes

The  effective tax rate was 18% for the three months ended June 30, 1997 and 20%
for the six months ended June 30, 1997 as compared with an effective tax rate of
20% for the same periods in 1996.

Inflation

The  effects of  inflation  on the  Company's  financial  results  have not been
significant to date.

Liquidity and Capital Resources

* For the six month period ended June 30, 1997,  cash  provided  from  operating
activities  was  $12,104,000  as  compared  to cash  used of  $6,041,000  in the

represents  proceeds from purchases made pursuant to the Company's  stock option
and employee  stock  purchase  plans and totaled  $2,703,000  for the six months
ended June 30,  1997.  The  Company  has relied  primarily  on cash  provided by
financing activities and net sales of short-term investments to fund operations,
capital  expenditures,  the repurchase  the Company's  common stock (see further
explanation  below),  and other investing  activities.  The Company's ability to
generate  cash from  operations  will depend in a large part on revenues and the
rate of collections of accounts  receivable.  Management believes that its cash,
cash equivalents and short-term  investment  balances,  with its existing credit
line,  will be  sufficient to meet its  anticipated  cash needs for at least one
year. At June 30, 1997, the Company had cash and cash equivalents of $31,443,000
and short-term investments of $57,028,000.

* In August 1995,  the Company  entered  into an agreement  with two banks for a
$30.0 million  unsecured  line of credit that expired in July 1997.  The line of
credit was  amended in July 1997 to extend  the line of credit to  September  1,
1997. The agreement  enables the Company to borrow up to $30.0 million  provided
that certain  financial and other covenants are met. The agreement  provides for
payment  of a  commitment  fee of 0.5%  for the  unused  portion  of the line of
credit.  Borrowings  bear interest at the higher of (i) one of the bank's annual
prime rate,  and (ii) the federal funds rate plus 0.5%. No borrowings  have been
made under this line of credit.  The Company  intends to obtain  another line of
credit on similar terms after this line expires.

In February  1996, the Company  announced  that it had approved a  discretionary
program  whereby up to 600,000  shares of its common stock may be repurchased by
the Company to offset potential  dilutive effects to earnings per share from the
issuance  of stock  options.  The Company  intends to use  existing  cash,  cash
equivalents  and short-term  investments  to finance any such stock  repurchases
under this program.  In 1996, the Company  purchased 250,000 shares at a cost of
$3,545,000. In the first quarter of 1997, the Company purchased 50,000 shares at
a cost of $673,000.  In the second quarter of 1997 the Company  purchased 89,500
shares at a cost of $1,161,000.

The  Company  is  continually   evaluating  potential  external  investments  in
technologies  related  to its  business  and to date has made  relatively  small
investments in GPS related technology companies.  There can be no assurance that
investments made to date and potential future investments will be successful.

Other Risk Factors

In the past,  revenue has tended to  fluctuate  on a quarterly  basis due to the
timing of shipments of products under contracts,  the sale of license rights and
seasonal  patterns  favoring  spring  and  summer  for  the  Commercial  Systems
business.  However,  the seasonal  patterns were not repeated in 1996,  however,
there  can  be  no  assurances  that  prior  seasonal  revenue  trends  will  be
experienced  during  1997.  A  significant  portion of the  Company's  quarterly
revenues are derived from orders received and  immediately  shipped to customers
in the last few weeks and days of a  quarter.  If orders  are not  received,  or
shipments are delayed  beyond the end of a quarter,  operating  results would be
significantly adversely impacted.



                                       13



* The Company has a relatively  fixed cost  structure in the short term which is
determined by the business plans and strategies the Company intends to implement
in the markets it addresses.  This effective  leveraging means that increases or
decreases  in  revenues  have more than a  proportional  impact on net income or
losses.  The Company  estimates  that a change in product  revenue of $1 million
would cause a corresponding change in the Company's earnings per share by 2 to 3
cents.

* In the longer term,  the Company  believes  that the  Software  and  Component
Technologies  business unit will comprise a significant portion of the Company's
business.  The  Software and  Component  Technologies  business  unit differs in
nature from most of the Company's  markets  because volumes are high and margins
relatively  low.  Software and  Component  Technologies  customers are extremely
price   sensitive.   To  the  extent,   if  any,  that  costs  decrease  through
technological advances, a portion of these cost savings will be passed on to the
customer. To compete in the Software and Component  Technologies market requires
high-volume  production  and  manufacturing  techniques.  Customers  expect high
quality  standards  with  very low  defect  rates.  The  Company  is  relatively
inexperienced  compared  to  competitors  with  far  greater  resources  in such
high-volume  manufacturing  and  associated  support  activities.  The Company's
failure to meet customer  expectations in this market could cause the Company to
lose customer  orders,  which could result in a material  adverse  effect on the
Company's operating results.

The  Company's  stock price is subject to  significant  volatility.  If revenues
and/or earnings fail to meet the expectations of the investment community, there
could  be an  immediate  and  significant  impact  on the  trading  price of the
Company's stock.

The  value of the  Company's  products  relies  substantially  on the  Company's
technical  innovation in fields in which there are many current patent  filings.
The  Company  recognizes  that as new  patents  are issued or are brought to the
Company's  attention by the holders of such patents, it may be necessary for the
Company to withdraw  products  from the market,  take a license from such patent
holders,  or redesign  its  products.  The  Company  does not believe any of its
products  infringe  patents or other  proprietary  rights of third parties,  but
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 the Company's revenues or profitability.
(See Note 4- Other Litigation:, to the financial statements)

The Company is  continually  evaluating  alliances and external  investments  in
technologies  related to its business and has already entered into alliances and
made  relatively  small  investments  in  GPS  related   technology   companies.
Acquisitions  of companies,  divisions of  companies,  or products and alliances
entail  numerous  risks,  including (i) the potential  inability to successfully
integrate acquired operations and products or to realize anticipated  synergies,
economies of scale or other value, (ii) diversion of management's attention, and
(iii) loss of key employees of acquired operations. Any such problems could have
a material  adverse effect on the Company's  business,  financial  condition and
results of  operations.  No  assurances  can be given that the Company  will not
incur problems from current or future alliances,  acquisitions,  or investments.
Furthermore,  there can be no assurance that the Company will realize value from
any such alliances, acquisitions, or investments.


                                       14



The  Company's  products rely on signals from the GPS Navstar  satellite  system
built and maintained by the U.S.  Department of Defense.  Navstar satellites and
their  ground  support  systems  are  complex   electronic  systems  subject  to
electronic  and  mechanical  failures  and possible  sabotage.  Some of these 24
satellites have exceeded their design lives of 7.5 years and are also subject to
damage by the hostile space environment in which they operate. Repair of damaged
or  malfunctioning   satellites  is  impossible.  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 of time, nor that policies of
the U.S.  Government  allowing  for the use of GPS  without  charge  will remain
unchanged. 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 the  Company's  products to select  GPS-based  systems
instead of products  based on competing  technologies.  Any resulting  change in
market  demand for GPS  products  would have a  material  adverse  effect on the
Company's  financial  results.  Certain European  government  organizations have
expressed concern  regarding the  susceptibility of GPS equipment to intentional
or inadvertent  signal  interference.  Such concern could translate into reduced
demand for GPS products in certain geographic regions.
