NOTE 1 - FINANCIAL STATEMENT PREPARATION

Data I/O  prepared  the  financial  statements  as of June 30, 2003 and June 30,
2002,  according to the rules and  regulations  of the  Securities  and Exchange
Commission  ("SEC").  These  statements  are  unaudited  but,  in the opinion of
management,  include all adjustments (consisting of normal recurring adjustments
and accruals) necessary to present fairly the results for the periods presented.
The  balance  sheet at  December  31,  2002 has been  derived  from the  audited
financial  statements  at  that  date.  We have  condensed  or  omitted  certain
information and footnote  disclosures  normally included in financial statements
prepared in accordance  with  accounting  principles  generally  accepted in the
United States of America according to such SEC rules and regulations.  Operating
results for the six months ended June 30, 2003 are not necessarily indicative of
the results  that may be expected for the year ending  December 31, 2003.  These
financial  statements  should be read in  conjunction  with the  annual  audited
financial  statements and the accompanying  notes included in the Company's Form
10-K for the year ended December 31, 2002.

Stock-Based Compensation

Data I/O has stock-based  employee  compensation plans. We apply APB Opinion 25,
Accounting  for Stock  Issued  to  Employees,  and  related  Interpretations  in
accounting for our plans.  Stock expense for the second quarter of 2003 and 2002
would have been the result of options  issued with an  exercise  price below the
underlying  stock's market price. The following table  illustrates the effect on
net income  (loss) and net income  (loss) per share if Data I/O had  applied the
fair  value  recognition  provisions  of  FASB  Statement  123,  Accounting  for
Stock-Based Compensation.

NOTE  4 - BUSINESS RESTRUCTURING PROGRESS

The economic slowdown of the past few years significantly affected our business.
During 2001 and 2002, we recorded  restructuring charges associated with actions
taken to  reduce  our  breakeven  point  and  realign  Data I/O with our  market
opportunities.  We required this operational repositioning because of the impact
of the  economic  slowdown  and the  decline in capital  spending  across a high
number of customer groups on general demand for programming equipment.

During the first quarter of 2003, we completed  most of the  previously  accrued
restructure actions.  These payments were $27,000 less than anticipated from the
original restructuring related charges that totaled $1.8 million during 2001 and
2002.  Accordingly,  included in the results for the first quarter is a reversal
of these  previously  over-accrued  restructure  charges.  At June 30, 2003, all
restructuring  expenses  associated with the activities  detailed above had been
paid, except approximately $17,000.

An analysis of the restructuring activity is as follows (in thousands):

(1)  At June 30,  2003 and 2002  there  were  1,384,775  and  1,327,919  shares,
     respectively,  of outstanding options potentially issuable as common stock.
     Because of the net loss for the six months ended June 30, 2002,  we did not
     include  potentially  issuable  common stock in the  calculation of diluted
     loss per share because this would be  anti-dilutive.  For options having an
     exercise  price  exceeding the market value of the common stock on June 30,
     2003,  we  included  the  dilutive  effect  of those  outstanding  options,
     potentially  issuable as common stock on that date, in the  calculation  of
     diluted income per share.

NOTE 6 - ACCOUNTING FOR INCOME TAXES

The Company's  effective tax rate for the first six months of 2003 differed from
the statutory 34% tax rate  primarily due to  utilization  of net operating loss
carryforwards.  The tax valuation allowance  decreased by approximately  $40,000
during the quarter ended June 30, 2003.  As of June 30, 2003,  the Company has a
valuation allowance of $10,044,000.

NOTE 7 - COMPREHENSIVE INCOME

During the second quarter of 2003 and 2002 total comprehensive income (loss) was
comprised of the following (in thousands):

NOTE 8 - FOREIGN CURRENCY TRANSLATION AND DERIVATIVES

Data I/O  translates  assets  and  liabilities  of foreign  subsidiaries  at the
exchange  rate on the  balance  sheet date.  We  translate  revenues,  costs and
expenses of foreign  subsidiaries at average rates of exchange prevailing during
the  year.  We  charge or credit  translation  adjustments  resulting  from this
process to stockholders' equity, net of taxes. Realized and unrealized gains and
losses  resulting  from the effects of changes in  exchange  rates on assets and
liabilities  denominated  in foreign  currencies  are included in  non-operating
expense as foreign currency transaction gains and losses.

Data I/O accounts for its hedging  activities in  accordance  with SFAS No. 133,
Accounting for Derivatives and Hedging  Activities.  This statement  establishes
accounting  and reporting  standards  for  derivative  instruments  and requires
recognition  of  derivatives  as  assets  or  liabilities  in the  statement  of
financial position and measurement of those instruments at fair value.

Data I/O utilizes  forward  foreign  exchange  contracts to reduce the impact of
foreign currency exchange rate risks where natural hedging  strategies cannot be
effectively  employed.  All hedging  instruments held by Data I/O are fair value
hedges.  Generally,  these  contracts  have  maturities  less  than one year and
require it to exchange  foreign  currencies  for U.S.  dollars at maturity.  The
change  in fair  value of the open  hedge  contracts  as of June 30,  2003 is an
unrealized  loss of $30,873 and is  included in accounts  payable on the balance
sheet.

Data I/O does not hold or issue  derivative  financial  instruments  for trading
purposes.  The purpose of our hedging  activities is to reduce the risk that the
valuation of the underlying  assets,  liabilities and firm  commitments  will be
adversely  affected by changes in exchange rates.  Our derivative  activities do
not create foreign currency exchange rate risk because fluctuations in the value
of the instruments  used for hedging  purposes are offset by fluctuations in the
value of the underlying exposures being hedged.

NOTE 9 - NEW ACCOUNTING PRONOUNCEMENTS

In November 2002, the Emerging Issues Task Force reached a consensus  opinion on
EITF 00-21,  "Revenue  Arrangements with Multiple  Deliverables."  The consensus
provides that revenue arrangements with multiple  deliverables should be divided
into separate units of accounting if certain criteria are met. The consideration
for the  arrangement  should be allocated to the  separate  units of  accounting
based on their relative fair values, with different provisions if the fair value
of all deliverables are not known or if the fair value is contingent on delivery
of specified items or performance  conditions.  Applicable  revenue  recognition
criteria  should be considered  separately for each separate unit of accounting.
EITF 00-21 is effective for revenue  arrangements entered into in fiscal periods
beginning  after  June 15,  2003.  Entities  may elect to report the change as a
cumulative  effect  adjustment  in  accordance  with APB Opinion 20,  Accounting
Changes. Data I/O has not determined the effect of adoption of EITF 00-21 on our
financial statements or the method of adoption it will use.

In May of 2003,  FASB  issued  Statement  149,  which  amends  Statement  133 by
clarifying various  derivatives  related issues and provides for more consistent
reporting of derivatives.  Statement 149 is effective for contracts entered into
or  modified  after  June  30,  2003,  with  some  exceptions,  and for  hedging
relationships  designated  after June 30, 2003.  Data I/O has not yet determined
the impact of this statement, but anticipates that it will be complying with the
provisions of the statement, which is to be applied prospectively.

In May 2003,  FASB issued  Statement  150,  "Accounting  for  Certain  Financial
Instruments with Characteristics of both Liabilities and Equity".  Statement 150
requires that certain financial instruments,  which under previous guidance were
accounted for as equity, must now be accounted for as liabilities. Statement 150
is effective for all financial  instruments  entered into or modified  after May
31, 2003.  The Company  adopted  Statement 150 on June 1, 2003.  The adoption of
Statement  150 did not have any  effect  on the  Company's  financial  position,
results of operations, or cash flows.

         and Results of Operations

General

Forward-Looking Statements

This Quarterly Report on Form 10-Q includes  forward-looking  statements  within
the meaning of the Private  Securities  Litigation  Reform Act of 1995. This Act
provides a "safe harbor" for  forward-looking  statements to encourage companies
to provide  prospective  information  about  themselves as long as they identify
these statements as forward-looking and provide meaningful cautionary statements
identifying important factors that could cause actual results to differ from the
projected results.  All statements other than statements of historical fact made
in this  Quarterly  Report  on Form  10-Q are  forward-looking.  In  particular,
statements  herein  regarding  industry  prospects or trends;  expected level of
expense;  future results of operations or financial position;  anticipated gross
margin;  integration of acquired  products and operations;  market acceptance of
our  newly  introduced  or  upgraded  products;  development,  introduction  and
shipment  of new  products;  and  any  other  guidance  on  future  periods  are
forward-looking  statements.  Forward-looking  statements  reflect  management's
current  expectations and are inherently  uncertain.  Although Data I/O believes
that  the  expectations  reflected  in  these  forward-looking   statements  are
reasonable, we cannot guarantee future results, levels of activity, performance,
achievements, or other future events. Moreover, neither Data I/O nor anyone else
assumes   responsibility   for  the   accuracy   and   completeness   of   these
forward-looking  statements.  Data I/O is under no duty to  update  any of these
forward-looking  statements after the date of this report. The reader should not
place  undue  reliance  on  these  forward-looking   statements.  The  following
discussions and the discussions in the section  entitled  "Business - Cautionary
Factors That May Affect Future Results" in Item 1 in the Company's Annual report
on Form 10-K for the year ended  December 31, 2002,  and in Exhibit 99.1 of this
report  describe  some,  but not all,  of the  factors  that could  cause  these
differences.

CRITICAL ACCOUNTING POLICY JUDGMENTS AND ESTIMATES

The preparation of financial statements in accordance with accounting principles
generally  accepted in the United  States  requires  that we make  estimates and
judgments,  which affect the reported amounts of assets,  liabilities,  revenues
and expenses,  and related disclosures of contingent assets and liabilities.  On
an on-going basis,  we evaluate our estimates,  including those related to sales
returns, bad debts, inventories,  investments,  intangible assets, income taxes,
warranty obligations,  restructuring charges,  contingencies such as litigation,
and contract terms that have multiple elements and other complexities typical in
the  telecommunications  equipment industry. We base our estimates on historical
experience  and other  assumptions  that we  believe  are  reasonable  under the
circumstances.  Actual results may differ from these  estimates  under different
assumptions or conditions.

We  believe  the  following  critical   accounting   policies  affect  the  more
significant  judgments and estimates  used in the  preparation  of our financial
statements.

Revenue Recognition:  Sales of our semiconductor  programming equipment products
requiring  installation  by us that is other than  perfunctory are recorded when
installation   is  complete,   or  at  the  later  of  customer   acceptance  or
installation,  if an  acceptance  clause is  specified  in the sales  terms.  We
recognize  revenue from other product  sales at the time of shipment.  We record
revenue from the sale of service and update contracts as deferred revenue and we
recognize it on a  straight-line  basis over the  contractual  period,  which is
typically one year. We establish a reserve for sales returns based on historical
trends in product  returns and  estimates  for new items.  If the actual  future
returns differ from historical levels, our revenue could be adversely affected.

Allowance for Doubtful  Accounts:  We base the  allowance for doubtful  accounts
receivable on our assessment of the collectibility of specific customer accounts
and the aging of accounts  receivable.  If there is a  deterioration  of a major
customer's  credit  worthiness  or actual  defaults  are higher than  historical
experience,  our  estimates  of the  recoverability  of amounts  due us could be
adversely affected.

Inventory  Provisions:  We base inventory  purchases and commitments upon future
demand  forecasts  and historic  usage.  If there is a  significant  decrease in
demand for our  products  or there is a higher  risk of  inventory  obsolescence
because of rapidly  changing  technology  and customer  requirements,  we may be
required to increase our inventory  provision  adjustments  and our gross margin
could be adversely affected.

Warranty  Accruals:  We accrue for warranty costs based on the expected material
and labor  costs to  fulfill  our  warranty  obligations.  If we  experience  an
increase in warranty  claims,  which are higher than our historical  experience,
our gross margin could be adversely affected.

Deferred  Taxes:  We have incurred tax losses in each of the last four years and
have net  operating  loss and tax credit  carryforwards  that begin  expiring in
2020.  We have  provided a full  valuation  allowance  against our  deferred tax
assets,  given the uncertainty as to their  realization.  In future years, these
benefits are available to reduce or eliminate taxes on future taxable income.

Revenues for the second quarter of 2003 increased by approximately  16% compared
to the second quarter of 2002.  Orders were slow early in the quarter,  which we
believe to be associated  with the impact of SARS,  but gained  momentum late in
the quarter. Backlog increased by approximately  $0.5 million to $1.9 million at
June  30,  2003.  Revenue  increased  due  primarily  to more  automated  system
aftermarket sales. Sales declined for non-automated  programming systems,  which
decline was primarily  related to fewer sales of a low-cost  programmer  product
line that we  distributed.  The vendor of this product line went out of business
and our  distribution  relationship  with this  vendor  ceased  during the first
quarter of 2003.  These  products  represented  $251,000 in revenue for the year
2002.  Finally,  the impact of the weakened US dollar favorably impacted us both
from making  products less  expensive  when sold overseas in US Dollars and from
Euro-based sales that translated into higher US Dollar reported sales.

Data I/O  continues  to  experience  a trend in its sales mix towards  increased
international sales and believes that, with the economic situation in the United
States and with the  electronics  industry trend toward  offshore and outsourced
manufacturing, this trend is likely to continue.

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


Gross  margins  increased in dollars and as a percentage of sales for the second
quarter of 2003  compared  with the same period of 2002.  Overall  gross margins
increased  primarily due to the increase in sales volume, cost reductions due to
the restructuring, and the second quarter of 2002 included unfavorable inventory
reserves of approximately $600,000. In addition,  margin percentages were higher
than  expected  due to the sales mix  including a larger  amount of software and
aftermarket products.  The translation net impact from the weaker US Dollar also
benefited the gross margin.  Looking forward,  we believe our expected sales mix
should result in a mid-50's gross margin percentage.

Research  and  development  ("R&D")  spending  for the  second  quarter  2003 as
compared to the second  quarter 2002 was less in dollars and as a percentage  of
sales.  This  decrease in spending was  primarily  related to the  restructuring
actions taken in the past year reducing  personnel  costs,  as well as lower R&D
material costs.

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


Selling,  general and administrative ("SG&A") expenses for the second quarter of
2003 declined compared with the same period in 2002, primarily due to Data I/O's
reduced  costs  from the prior  year's  restructuring  activities  offset by our
recording of increased incentive compensation and higher  facility-related costs
due to the loss of a sublease  tenant and a rent  increase  in 2002.  Data I/O's
management  incentive  compensation  and  employee  performance  bonus plans are
earned based upon  various  measures of  quarterly  profit and annual  growth in
profit that will be an incremental  expense for any profits in 2003, as compared
to our fiscal year 2002, in which we had a net loss.

Financial Condition

Liquidity and Capital Resources

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


Working capital  increased  during the first six months of 2003 primarily due to
cash provided by operations.  Cash, cash  equivalents and marketable  securities
increased  approximately  $0.6 million during this period,  inventory  increased
$0.2 million,  and accounts  receivable  increased $0.2 million,  while accounts
payable  decreased by $0.4 million.  We have  continued to focus on reducing the
amount of inventory  relative to our business level,  especially through a focus
on lean  manufacturing  processes.  Should our business grow  significantly,  we
anticipate  that we  will  need to  utilize  existing  liquidity  to  carry  the
increased receivables and inventory expected to be associated with sales growth.
As of June 30, 2003, Data I/O had no debt outstanding.

Data I/O estimates that capital  expenditures for property,  plant and equipment
during the remainder of 2003 will be between $300,000 and $1 million,  excluding
expenditures for strategic purposes. Data I/O's future capital requirements will
depend on a number of factors  including;  decisions  to invest in new  systems,
computers,  software and technology  equipment;  costs associated with R&D; cost
related  to the  launch  of new  products;  and the  potential  use of funds for
strategic  purposes.  We expect to fund capital  expenditures  from existing and
internally generated funds or we may lease capital equipment. We believe that we
have sufficient  working capital  available under our operating plan to fund our
operations and capital requirements for at least 12 months.

Data I/O renewed a foreign line of credit for 50,000 Euros in the first quarter,
and maintains credit facilities for purchasing card and credit card purchases.

General

Restructuring

The economic slowdown of the past few years significantly affected our business.
During 2001 and 2002, we recorded  restructuring charges associated with actions
taken to  reduce  our  breakeven  point  and  realign  Data I/O with our  market
opportunities.  We required this operational repositioning because of the impact
of the  economic  slowdown  and the  decline in capital  spending  across a high
number of customer groups on general demand for programming equipment.

During the first six months of 2003, we completed most of the previously accrued
restructure actions.  These payments were $27,000 less than anticipated from the
original restructuring related charges that totaled $1.8 million during 2001 and
2002. Accordingly, included in the results for the first six months of 2003 is a
reversal of these previously over-accrued restructure charges. At June 30, 2003,
all  restructuring  expenses  associated with the activities  detailed above had
been paid, except  approximately  $17,000,  which was primarily  associated with
severance, facility, consulting and legal fees.

New Accounting Pronouncements

In November 2002, the Emerging Issues Task Force reached a consensus  opinion on
EITF 00-21,  "Revenue  Arrangements with Multiple  Deliverables."  The consensus
provides that revenue arrangements with multiple  deliverables should be divided
into separate units of accounting if certain criteria are met. The consideration
for the  arrangement  should be allocated to the  separate  units of  accounting
based on their relative fair values, with different provisions if the fair value
of all deliverables are not known or if the fair value is contingent on delivery
of specified items or performance  conditions.  Applicable  revenue  recognition
criteria  should be considered  separately for each separate unit of accounting.
EITF 00-21 is effective for revenue  arrangements entered into in fiscal periods
beginning  after  June 15,  2003.  Entities  may elect to report the change as a
cumulative  effect  adjustment  in  accordance  with APB Opinion 20,  Accounting
Changes. Data I/O has not determined the effect of adoption of EITF 00-21 on our
financial statements or the method of adoption it will use.

In May of  2003  FASB  issued  Statement  149,  which  amends  Statement  133 by
clarifying  various  derivative  related issues and provides for more consistent
reporting of derivatives.  Statement 149 is effective for contracts entered into
or  modified  after  June  30,  2003,  with  some  exceptions,  and for  hedging
relationships  designated  after June 30, 2003.  Data I/O has not yet determined
the impact of this statement, but anticipates that it will be complying with the
provisions of the statement, which is to be applied prospectively.

In May 2003,  FASB issued  Statement  150,  "Accounting  for  Certain  Financial
Instruments with Characteristics of both Liabilities and Equity".  Statement 150
requires that certain financial instruments,  which under previous guidance were
accounted for as equity, must now be accounted for as liabilities. Statement 150
is effective for all financial  instruments  entered into or modified  after May
31, 2003.  The Company  adopted  Statement 150 on June 1, 2003.  The adoption of
Statement  150 did not have any  effect  on the  Company's  financial  position,
results of operations, or cash flows.


Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to financial market risks, including fluctuations in foreign
exchange rates and interest rates.

INTEREST RATE RISK

We invest our cash in a variety of short-term financial  instruments,  including
government  bonds,  commercial  paper and money  market  instruments,  which are
classified as available-for-sale. Our investments are made in accordance with an
investment  policy  approved  by  our  board  of  directors.  Our  portfolio  is
diversified and consists  primarily of investment  grade  securities to minimize
credit risk. Cash balances in foreign  currencies are operating balances and are
invested in demand or short-term deposits of the local operating bank.

Investments  in both fixed rate and floating rate interest  earning  instruments
carry a degree of interest rate risk.  Fixed rate securities may have their fair
market  value  adversely  impacted  because of a rise in interest  rates,  while
floating rate securities may produce less income than expected if interest rates
fall. Due in part to these factors,  our future investment income may fall short
of expectations  because of changes in interest rates or we may suffer losses in
principal if forced to sell  securities that have seen a decline in market value
because of changes in interest  rates.  We do not attempt to reduce or eliminate
our  exposure to interest  rate risk  through  the use of  derivative  financial
instruments due to the short-term nature of the investments.

The table below provides information about our marketable securities,  including
principal  cash  flows  and the  related  weighted  average  interest  rates (in
thousands):

FOREIGN CURRENCY RISK

We have operations in Germany,  Canada, and China and, therefore, we are subject
to risks typical of an  international  business  including,  but not limited to,
differing  economic  conditions,  changes in political  climate,  differing  tax
structures,  other  regulations  and  restrictions  and  foreign  exchange  rate
volatility.  Accordingly,  our  future  results  could be  materially  adversely
affected by changes in these or other factors.

Our sales and corresponding  receivables are substantially in U.S. dollars other
than sales made in our subsidiaries in Germany,  Canada, and China.  Through our
operations  in Germany,  Canada,  and China,  we incur  certain  product  costs;
research and development;  customer service and support costs; selling,  general
and administrative  expenses in local currencies.  We are exposed, in the normal
course of  business,  to foreign  currency  risks on these  expenditures  and on
related foreign currency  denominated  monetary assets and liabilities.  We have
evaluated  our  exposure to these risks and  believe  that our only  significant
exposure to foreign  currencies  at the  present  time is  primarily  related to
Euro-based  receivables.  We use forward contracts to hedge and thereby minimize
the currency risks associated with certain transactions denominated in Euros.

If our actual currency  requirement or timing in the period  forecasted  differs
materially from the notional amount of our forward  contracts and/or the natural
balancing of receivables and payables in foreign  currencies  during a period of
currency  volatility  or if we do not continue to manage our exposure to foreign
currency  through  forward   contracts  or  other  means,  we  could  experience
unanticipated  foreign  currency  gains or  losses.  In  addition,  our  foreign
currency  risk   management   policy  subjects  us  to  risks  relating  to  the
creditworthiness  of the  commercial  banks  with  which we enter  into  forward
contracts.  If one of these banks cannot honor its obligations,  we may suffer a
loss. We also invest in our international  operations,  which will likely result
in increased future operating expenses denominated in those local currencies. In
the future,  our  exposure to foreign  currency  risks from these other  foreign
currencies may increase and if not managed  appropriately,  we could  experience
unanticipated foreign currency gains and losses.

The  purpose of our foreign  currency  risk  management  policy is to reduce the
effect of exchange rate  fluctuation  on our results of  operations.  Therefore,
while our foreign  currency  risk  management  policy may reduce our exposure to
losses  resulting from unfavorable  changes in currency  exchange rates, it also
reduces or eliminates our ability to profit from  favorable  changes in currency
exchange rates.

At June 30, 2003,  we had nine  forward  contracts to sell Euros in exchange for
$1,195,375 with rates ranging from 1.0621 to 1.1698 and a weighted  average rate
of 1.124,  all  scheduled  to be due  within  the next  quarter  with a value at
maturity of $1,201,631.


Item 4.  Controls and Procedures

Our management,  with the participation of our Chief Executive Officer and Chief
Financial  Officer,  evaluated the effectiveness of our disclosure  controls and
procedures (as defined in Rule  13a-15(e)  under the Exchange Act) as of the end
of the period  covered by this report  (the  "Evaluation  Date").  Based on this
evaluation,  as of the Evaluation  Date, our Chief  Executive  Officer and Chief
Financial  Officer have concluded  that our  disclosure  controls and procedures
were effective in timely alerting them to the material  information  relating to
Data I/O  required to be included in the reports  that Data I/O files or submits
under the Exchange Act.

There were no changes in internal  control over financial  reporting  during the
period covered by this report that have materially  affected,  or are reasonably
likely to materially affect, this control over financial reporting.

Our  management,  including  the Chief  Executive  Officer  and Chief  Financial
Officer, does not expect that its disclosure controls and procedures or internal
control over financial reporting will prevent all error and all fraud. A control
system, no matter how well conceived and operated,  can provide only reasonable,
not  absolute,  assurance  that the  objectives  of the control  system are met.
Further,  the design of a control  system  must  reflect the fact that there are
resource  constraints,  and the benefits of controls must be considered relative
to their costs.  Because of the inherent  limitations in all control systems, no
evaluation of controls can provide  absolute  assurance  that all control issues
and  instances  of fraud,  if any,  within  Data I/O have been  detected.  These
inherent limitations include the realities that judgments in decision-making can
be faulty,  and that  breakdowns  can occur  because of simple error or mistake.
Additionally,  controls  can be  circumvented  by the  individual  acts  of some
persons,  by collusion of two or more people,  or by management  override of the
control. The design of any system of controls also is based in part upon certain
assumptions about the likelihood of future events, and there can be no assurance
that any design will succeed in achieving  its stated goals under all  potential
future  conditions;  over time, control may become inadequate because of changes
in conditions,  or the degree of compliance  with the policies or procedures may
deteriorate.  Because of the inherent  limitations in a  cost-effective  control
system, misstatements due to error or fraud may occur and not be detected.

Exhibit 99.1

Cautionary Factors That May Affect Future Results

Data I/O's  disclosure  and  analysis in this  Quarterly  Report  contains  some
forward-looking  statements.  Forward-looking  statements  include  our  current
expectations  or  forecasts  of future  events.  The reader can  identify  these
statements by the fact that they do not relate strictly to historical or current
facts.  In  particular,  these  include  statements  relating to future  action,
prospective products, new technologies, future performance or results of current
and anticipated  products,  sales efforts,  expenses,  outsourcing of functions,
outcome of contingencies, and financial results.

Any or all of the forward-looking  statements in this Quarterly Report or in any
other public  statement  made may turn out to be wrong.  They can be affected by
inaccurate   assumptions   we  might  make  and  known  or  unknown   risks  and
uncertainties.  Many factors -- for  example,  product  competition  and product
development  -- will be  important  in  determining  future  results.  Moreover,
neither  Data I/O nor anyone else  assumes  responsibility  for the accuracy and
completeness  of these  forward-looking  statements.  Actual future  results may
materially vary.

We undertake no obligation  to publicly  update any  forward-looking  statements
after the date of this Quarterly Report, whether as a result of new information,
future events or otherwise.  The reader should not place undue  reliance on such
forward-looking  statements.  The reader is  advised,  however,  to consult  any
future  disclosures Data I/O makes on related subjects in our 10-Q, 8-K and 10-K
reports to the SEC and press  releases.  Also,  note that Data I/O  provides the
following cautionary discussion of risks,  uncertainties and possible inaccurate
assumptions  relevant to our  business.  These are  factors  that we think could
cause  Data  I/O's  actual  results  to  differ  materially  from  expected  and
historical results. Other factors besides those listed here could also adversely
affect  Data  I/O.  This  discussion  is  permitted  by the  Private  Securities
Litigation Reform Act of 1995.

RISK FACTORS

Development, Introduction and Shipment of New Products

Data I/O  currently is developing  new  engineering  and  automated  programming
systems.  Significant technological,  supplier,  manufacturing or other problems
may delay the development, introduction or production of these products.

For example, we may encounter these problems:

o technical problems in the development of a new programming system platform or
  the robotics for new automated handing systems

o inability to hire qualified personnel

o delays or failures to perform by third parties involved in our development
  projects

Delays in the development,  completion and shipment of new products,  or failure
of  customers  to accept  new  products,  may  result  in a decline  in sales or
additional costs in 2003 and beyond.

Variability in Quarterly Operating Results

Data I/O's operating  results tend to vary from quarter to quarter.  Our revenue
in each quarter  substantially depends upon orders received within that quarter.
Conversely,  our  expenditures  are based on  investment  plans and estimates of
future revenues. We may, therefore,  be unable to quickly reduce our spending if
our revenues decline in a given quarter. As a result, operating results for that
quarter  will  suffer.  Our  results of  operations  for any one quarter are not
necessarily indicative of results for any future periods.

Other factors, which may cause our quarterly operating results to fluctuate,
include:

o increased competition

o timing of new product announcements

o product releases and pricing changes by us or our competitors

o market acceptance or delays in the introduction of new products

o production constraints

o labor or material shortages

o the timing of significant orders

o war or terrorism

o health issues (such as SARS)

o customers' budgets

o adverse movements in exchange rates, interest rates or tax rates

o cyclical nature of demand for our customers' products

o general economic conditions in the countries where we sell products

Due  to all of the  foregoing  factors,  it is  possible  that  in  some  future
quarters,  our  operating  results  will be below  expectations  of analysts and
investors.

Rapid Technological Change

Product technology in Data I/O's industry evolves rapidly, making timely product
innovation  essential to success in the marketplace.  Introducing  products with
improved  technologies or features may render our existing products obsolete and
unmarketable.  Technological  advances that may  negatively  impact our business
include:

o new device package types, densities, and technologies requiring hardware and
  software changes in order to be programmed by our products

o electronics equipment manufacturing practices, such as widespread use of
  in-circuit programming

o customer software platform preferences different from those on which our
  products operate

o more rigid industry standards, which would decrease the value-added element of
  our products and support services

If we cannot  develop  products  in a timely  manner  in  response  to  industry
changes,  or if our products do not perform  well,  our  business and  financial
condition will be adversely affected. Also, our new products may contain defects
or errors  that give rise to product  liability  claims  against us or cause our
products to fail to gain market  acceptance.  Our future success  depends on our
ability to successfully  compete with other  technology  firms in attracting and
retaining key technical personnel.

Economic and Market Conditions

Our business is highly  impacted by capital  spending  plans and other  economic
cycles  that  affect  the  users  and  manufacturers  of  semiconductors.  These
industries  are highly  cyclical and are  characterized  by rapid  technological
change,  short product life cycles,  fluctuations in manufacturing  capacity and
pricing and gross margin  pressures.  As we  experienced in 2002, our operations
may in the future reflect  substantial  fluctuations from  period-to-period as a
consequence of these industry patterns,  general economic  conditions  affecting
the timing of orders from major customers,  and other factors  affecting capital
spending. These factors could have a material adverse effect on our business and
financial condition.

History of Losses

We have  incurred  net losses in each of our last three  fiscal  years.  We have
decreased our operating  expenses in recent  periods  through the  restructuring
plans that we  initiated  during our prior  fiscal  year.  We will  continue  to
examine our level of operating  expense based upon our projected  revenues.  Any
planned  increases in operating  expenses may result in larger  losses in future
periods if projected  revenues  are not  achieved.  As a result,  we may need to
generate  greater  revenues  than we  have  recently  to  achieve  and  maintain
profitability.  However,  we cannot  provide  assurance  that our revenues  will
increase and our strategy may not be successful, resulting in future losses.

Affects of Restructuring Activities

Beginning in the prior fiscal year and  continuing  in the past fiscal year,  we
reduced  our  workforce  from  224 to 125  employees.  There  have  been and may
continue  to be  substantial  costs  associated  with this  workforce  reduction
related to severance and other employee-related costs and our restructuring plan
may  yield  unanticipated   consequences,   such  as  increased  burden  on  our
administrative,  operational,  and  financial  resources  and has  increased the
responsibilities  for our  management  personnel.  As a result,  our  ability to
respond to  unexpected  challenges  may be impaired and we may be unable to take
advantage of new opportunities.

In addition,  many of the  employees  that were  terminated  possessed  specific
knowledge or expertise,  and that  knowledge or expertise may prove to have been
important to our operations.  In that case, their absence may create significant
difficulties. Further, the reduction in workforce may reduce employee morale and
may create concern among current and potential  employees  about job security at
Data I/O,  which may lead to difficulty in hiring and retaining  employees,  and
divert management's attention. In addition, the headcount reductions may subject
us to the risk of  litigation,  which  could  result in  substantial  cost.  Any
failure by us to properly manage this rapid change in workforce could impair our
ability to efficiently  manage our business,  to maintain and develop  important
relationships with third-parties,  and to attract and retain customers. It could
also cause us to incur higher  operating cost and delays in the execution of our
business plan or in the reporting or tracking of our financial results.

Need for Additional Funding

Our  past  revenues  have  been  and our  future  revenues  may  continue  to be
insufficient  to support the expense of our  operations and any expansion of our
business. We may therefore need additional equity or debt capital to finance our
operations.  If we are unable to generate  sufficient cash flows from operations
or to obtain funds through  additional debt or equity financing,  we may have to
reduce some or all of our development and sales and marketing  efforts and limit
the expansion of our business.

We believe our existing cash and cash equivalents will be sufficient to meet our
working capital  requirements  for at least the next twelve months.  Thereafter,
depending on the  development of our business,  we may need to raise  additional
cash for working capital or other expenses. We may also encounter  opportunities
for  acquisitions or other business  initiatives  that require  significant cash
commitments,  or  unanticipated  problems  or  expenses  that could  result in a
requirement for additional cash before that time.

Therefore,  we may seek  additional  funding  through  public or private debt or
equity  financing or from other sources.  We have no commitments  for additional
financing,  and we may experience  difficulty in obtaining  funding on favorable
terms,  if at all. Any financing we obtain may contain  covenants  that restrict
our freedom to operate our business or may require us to issue  securities  that
have rights, preferences or privileges senior to our Common Stock and may dilute
your ownership interest.

Competition

Technological  advances have reduced the barriers of entry into the  programming
systems  markets.  We expect  competition to increase from both  established and
emerging  companies.  If we fail to compete  successfully  against  current  and
future sources of competition,  our profitability and financial performance will
be adversely impacted.

Dependence on Semiconductor Manufacturers

We work  closely  with  most  semiconductor  manufacturers  to  ensure  that our
programming   systems  comply  with  their  requirements.   In  addition,   many
semiconductor  manufacturers  recommend our programming systems for use by users
of their programmable devices. These working relationships enable us to keep our
programming systems product line up to date and provide end-users with broad and
current  programmable device support.  Our business may be adversely affected if
our relationships with semiconductor manufacturers deteriorate.

Dependence on Suppliers

Certain parts used in our products are currently  available from either a single
supplier or from a limited number of suppliers. If we cannot develop alternative
sources of these components,  if sales of parts are discontinued by the supplier
or we experience  deterioration in our relationship with these suppliers,  there
may be delays or reductions  in product  introductions  or shipments,  which may
materially adversely affect our operating results.

Because we rely on a small number of suppliers for certain parts, we are subject
to  possible  price  increases  by these  suppliers.  Also,  we may be unable to
accurately forecast our production schedule. If we under estimate our production
schedule,  suppliers may be unable to meet our demand for components. This delay
in the supply of key components may  materially  adversely  affect our business.
Over  estimation  of  demand  will lead to excess  inventories  that may  become
obsolete.

The non-automated programming system products we acquired when we acquired SMS
in November 1998 are currently manufactured to our specifications by a
third-party foreign contract manufacturer. We may not be able to obtain a
sufficient quantity of these products if and when needed, which may result in
lost sales.





Reliance on Third-Party Distribution Channels

Data  I/O  has  an   internal   sales  force  and  also   utilizes   third-party
representatives,  and distributors.  Therefore, the financial stability of these
distributors is important. Highly skilled professional engineers use most of our
products.  To be effective,  third-party  distributors must possess  significant
technical,  marketing  and sales  resources  and must devote their  resources to
sales  efforts,  customer  education,   training  and  support.  These  required
qualities limit the number of potential third-party  distributors.  Our business
will suffer if we cannot  attract and retain a  sufficient  number of  qualified
third-party distributors to market our products.

International Operations

International sales represented 64% of our net revenue for the fiscal year ended
December  31, 2002.  We expect that  international  sales will  continue to be a
significant portion of our net revenue. International sales may fluctuate due to
various factors, including:

o migration of manufacturing to low cost geographies

o unexpected changes in regulatory requirements

o tariffs and taxes

o difficulties in staffing and managing foreign operations

o longer average payment cycles and difficulty in collecting accounts receivable

o fluctuations in foreign currency exchange rates

o impact of the Euro

o compliance with applicable export licensing requirements

o product safety and other certification requirements

o political and economic instability

o local competitors focused on their local market

The European  Community and European  Free Trade  Association  have  established
certain electronic emission and product safety requirements ("CE"). Although our
products  currently  meet  these  requirements,  failure  to obtain  either a CE
certification  or a waiver for any product may  prevent us from  marketing  that
product in Europe.

We operate subsidiaries in Germany, China and Canada. Our business and financial
condition  is  sensitive to currency  exchange  rates or any other  restrictions
imposed on their currencies. Currency exchange fluctuations in Canada, China and
Germany may adversely affect our investment in our subsidiaries.

Protection of Intellectual Property

Data I/O also relies on patents,  copyrights,  trade  secrets and  trademarks to
protect our intellectual  property, as well as product development and marketing
skill to establish  and protect our market  position.  We attempt to protect our
rights in proprietary  software products,  including TaskLink and other software
products,  by  retaining  the  title  to  and  copyright  of  the  software  and
documentation,  by including  appropriate  contractual  restrictions  on use and
disclosure  in  our  licenses,   and  by  requiring  our  employees  to  execute
non-disclosure agreements. Our software products are typically shipped in sealed
packages,  or on CDs, on which notices are prominently  displayed  informing the
end-user  that,  by  breaking  the  seal of the  packaging,  or  installing  the
software,  the end-user agrees to be bound by the license agreement contained in
the  package or product.  The  license  agreement  includes  limitations  on the
end-user's  authorized use of the product, as well as restrictions on disclosure
and  transferability.  The  legal and  practical  enforceability  and  extent of
liability for violations of license  agreements that purport to become effective
upon opening of a sealed package or installation of the product are unclear.  We
are  not  aware  of any  situation  where a  license  agreement  restricting  an
end-user's authorized use of a licensed product resulted in enforcement action.

Because of the rapidly  changing  technology  in the  semiconductor,  electronic
equipment  and  software  industries,  portions of our products  might  possibly
infringe upon existing patents or copyrights, and we may, therefore, be required
to obtain  licenses or  discontinue  the use of the  infringing  technology.  We
believe that any exposure we may have regarding possible  infringement claims is
a reasonable  business  risk  similar to that assumed by other  companies in the
electronic   equipment   and  software   industries.   However,   any  claim  of
infringement,  with or  without  merit,  could  be  costly  and a  diversion  of
management's attention,  and an adverse determination could adversely affect our
reputation,  preclude  us from  offering  certain  products,  and  subject us to
substantial liability.

Acquisitions

We may pursue  acquisitions  of  complementary  technologies,  product  lines or
businesses. Future acquisitions may include risks, such as:

o burdening management and our operating teams during the integration of the
  acquired entity

o diverting management's attention from other business concerns

o failing to successfully integrate the acquired products

o lack of acceptance of the acquired products by our sales channels or customers

o entering markets where we have no or limited prior experience

o potential loss of key employees of the acquired company

o additional burden of support for an acquired programmer architecture

Future acquisitions may also impact Data I/O's financial position.  For example,
we may use significant  cash or incur  additional  debt,  which would weaken our
balance sheet. We may also capitalize  goodwill and intangible  assets acquired,
the impairment of which would reduce our profitability. We cannot guarantee that
future acquisitions will improve our business or operating results.

Dependence on Key Personnel

We have  employees  located in the U.S.,  Germany,  Canada  and  China.  We also
utilize  independent  contractors for specialty work,  primarily in research and
development,  and utilize  temporary  workers to adjust  capacity to fluctuating
demand.  Many of our employees are highly skilled and our continued success will
depend in part upon our  ability to attract and retain  employees  who can be in
great demand within the industry.  None of our  employees are  represented  by a
collective  bargaining  unit and we believe  relations  with our  employees  are
favorable  though  no  assurance  can be made  that this will be the case in the
future.  Refer to the section  captioned  "Affects of Restructuring  Activities"
above.

Potential Volatility of Stock Price

The stock prices of technology  companies tend to fluctuate  significantly,  and
many experienced  significant  reductions in value during the past few years. We
believe factors such as  announcements  of new products by us or our competitors
and quarterly variations in financial results may cause the market price of Data
I/O's Common Stock to fluctuate substantially.  In addition,  overall volatility
in the stock market,  particularly in the technology  company  sector,  is often
unrelated  to  the  operating   performance   of  companies.   If  these  market
fluctuations continue in the future, they may adversely affect the price of Data
I/O's Common Stock.
