                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

NOTE 1 - FINANCIAL STATEMENT PREPARATION

Data I/O prepared the  financial  statements  as of March 31, 2004 and March 31,
2003,  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,  2003 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 three months ended March 31, 2004 are not necessarily indicative
of the results that may be expected for the year ending December 31, 2004. 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, 2003.

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 first quarter of 2004 and 2003
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  and  earnings  per  share if Data I/O had  applied  the fair  value
recognition  provisions  of  FASB  Statement  123,  Accounting  for  Stock-Based
Compensation.

2002 previously  accrued  restructure  charges  associated with actions taken to
reduce our breakeven  point and realign Data I/O with our market  opportunities.
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 2003 was a reversal of these previously
over-accrued  restructure  charges.  At December  31,  2003,  all  restructuring
expenses associated with the activities detailed above had been paid.

NOTE 6 - ACCOUNTING FOR INCOME TAXES

The  Company's  effective  tax rate for the first three months of 2004  differed
from the statutory 34% tax rate  primarily due to  utilization  of net operating
loss  carryforwards.  The tax  valuation  allowance  increased by  approximately
$46,000  during the quarter  ended March 31,  2004.  As of March 31,  2004,  the
Company has a valuation allowance of $9,783,000.

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 us are fair value hedges.
Generally,  these contracts have maturities less than one year and require us to
exchange  foreign  currencies for U.S.  dollars at maturity.  The change in fair
value of the open hedge  contracts as of March 31, 2004 is an unrealized loss of
$4,100 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.

December 31, 2003,  and in Exhibit 99.1 of this report  describe  some,  but not
all, of the factors that could cause these differences.



OVERVIEW

Our goal is to continue to focus on managing the business to achieve  profitable
operations,  while  developing  and  enhancing  products  to drive  revenue  and
earnings  growth.  Our  challenge  continues  to be  operating  in the  weak and
uncertain economic environment with its limited capacity related demand and weak
capital spending, while positioning Data I/O to take advantage of an anticipated
recovery in capital spending. We expect that demand for capacity should improve,
in part based on  forecasted  increased  2004 unit  sales for the  semiconductor
industry, which should provide improved business opportunities for Data I/O.

We are  continuing  our  efforts  to  balance  increasing  costs  and  strategic
investments  in our  business  with the level of demand and mix of  business  we
expect.  We are focusing our research and  development  efforts in our strategic
growth  markets,  namely new  programming  technology and automated  programming
systems  for  the   manufacturing   environment,   particularly   extending  the
capabilities   and   support   for   our   FlashCORE    architecture   and   the
ProLINE-RoadRunner  and PS families.  To better  support our  customers in their
geographic  areas and time zones, we have expanded device support  operations in
Germany  and India and are in the  process of  setting  up a new device  support
center in Shanghai, China.

Our  customer  focus  has  been  on  strategic  high  volume  manufacturers  and
programming centers and supporting NAND Flash and  microcontrollers on our newer
products  to  gain  new   accounts   and  break  into  new   markets,   such  as
microcontrollers  for the automotive market. We are in the process of setting up
new  subsidiaries in China and Brazil.  We are expanding our China operations to
take advantage of the growth of  manufacturing  in China and are  establishing a
service  operation  in Brazil.  We  continue  our  efforts  to partner  with the
semiconductor manufacturers to better serve our mutual customers.

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 its 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
2019. We have provided a full valuation allowance against our 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 first quarter of 2004 increased by  approximately  11% compared
to the first  quarter of 2003.  The revenue  increase  relates to our  increased
sales of automated systems,  especially aftermarket products. Our revenue growth
is due to the increased  sales in Asia.  The impact of the weakened U.S.  Dollar
continues to favorably impact us both from making products made in the U.S. less
expensive  when sold overseas in U.S.  Dollars and from  Euro-based  sales which
translated into higher U.S.  Dollar reported sales.  During the first quarter of
2004, our backlog of orders was reduced from $1.5 million to $820,000.

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 but  decreased as a percentage of sales for
the first quarter of 2004  compared with the same period of 2003.  Overall gross
margins  increased  primarily  due to the  increase  in sales  volume  and to an
increase in the  aftermarket  sales mix.  The higher  gross margin was offset in
part by  unfavorable  labor and overhead  variances  associated  with a $555,000
reduction in inventory during the quarter. Gross margins were favorably impacted
by the export  and  currency  translation  effects  of the  weaker  U.S.  Dollar
compared  to  the  Euro.  We  continue  to  forecast   margin   percentages   at
approximately the current quarter's level.

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


Research and development ("R&D") spending for the first quarter 2004 as compared
to the first  quarter 2003 was slightly more in dollars but less as a percentage
of sales. This increase in spending was primarily related to our new development
initiative in In-System Programming (ISP). During the quarter, we introduced the
new PS-288FC automated programming system, along with several other products. We
plan to  increase  our  engineering  development  spending  during 2004 with the
hiring of new  engineering  positions in our new Shanghai  based  subsidiary  in
China formed in April of 2004.

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


Selling,  general and administrative  ("SG&A") expenses for the first quarter of
2004 were $244,000 more compared with the same period in 2003,  primarily due to
our strategic investments in Asia and the hiring of additional key personnel, as
well as the unfavorable  currency translation impact of European based operating
costs.  In addition,  we incurred  higher  commission  costs based on the higher
sales volume and a higher mix of  representative  sales vs.  distributor  sales.
Finally,  higher  expenses  related to Asian sales  meetings  and travel,  which
expenses  were  significantly  less in the  first  quarter  of  2003  due to the
cancellation of Asian sales meetings and travel as a result of SARS.

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


Working capital decreased during the first three months of 2004 primarily due to
cash used by  operations.  Cash,  cash  equivalents  and  marketable  securities
decreased  approximately  $0.7  million  during this  period,  primarily  due to
payment of accrued  liabilities;  inventory decreased $0.6 million: and accounts
receivable  increased $0.6 million.  We continue to focus on reducing the amount
of inventory relative to our business level. Our receivables  increase is due in
part to the increased mix of  international  sales,  which typically have longer
sales terms and collection periods.  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 March 31, 2004, Data I/O had no debt outstanding.

Data I/O estimates that capital  expenditures for property,  plant and equipment
during  the  remainder  of  2004  will  be  approximately  $500,000,   excluding
expenditures for strategic purposes. Data I/O's future capital requirements will
depend on a number of  factors  including  international  operations  expansion,
decisions to invest in new systems and technology  equipment,  costs  associated
with R&D,  successful  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.

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 are setting up operations
in  Brazil.  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 and soon in Brazil,  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 March 31,  2004,  we had two forward  contracts to sell Euros in exchange for
$341,960 with rates ranging from 1.1996 to 1.2145 all scheduled to be due within
the next quarter and the value at that date of $333,727.

Item 4. Controls and Procedures

(a) Evaluation of disclosure controls and procedures.

Under the supervision and with the  participation  of our management,  including
our Chief Executive Officer and Chief Financial Officer,  Data I/O evaluated the
effectiveness  of the  design  and  operation  of our  disclosure  controls  and
procedures (as defined in Rule  13a-15(e) and Rule 15d-15(e)  under the Exchange
Act) as of the end of the period covered by this report (the "Evaluation Date").
Based upon that  evaluation,  the Chief  Executive  Officer and Chief  Financial
Officer  concluded that, as of the Evaluation Date, our disclosure  controls and
procedures  were effective in timely  alerting them to the material  information
relating to Data I/O (or its consolidated  subsidiaries) required to be included
in our periodic SEC filings and Form 8-K reports.



(b) Changes in internal controls.

There were no  significant  changes  made in our  internal  controls  or, to our
knowledge,  in other  factors that could  significantly  affect  these  controls
subsequent to the date of their evaluation.

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.

          graded schedule (if the plan currently has a graded schedule that does
          not satisfy  EGTRRA) or a 3 year cliff schedule (if the plan currently
          has a cliff schedule that does not satisfy EGTRRA),  and such schedule
          will apply to all  matching  contributions  (even  those made prior to
          2002).
     2)   Rollovers are automatically excluded in determining whether the $5,000
          threshold has been  exceeded for  automatic  cash-outs (if the plan is
          not subject to the  qualified  joint and  survivor  annuity  rules and
          provides for automatic cash-outs). This is applied to all participants
          regardless of when the distributable event occurred.
     3)   The suspension period after a hardship  distribution is made will be 6
          months and this will only apply to hardship  distributions  made after
          2001.
     4)   Catch-up contributions will be allowed.
     5)   For target benefit plans, the increased compensation limit of $200,000
          will be applied retroactively (i.e., to years prior to 2002).

2.1      Vesting Schedule for Matching Contributions

          If there are matching contributions subject to a vesting schedule that
          does not satisfy  EGTRRA,  then unless  otherwise  elected below,  for
          participants  who complete an hour of service in a plan year beginning
          after December 31, 2001, the following  vesting schedule will apply to
          all matching contributions subject to a vesting schedule:

          If the plan has a graded vesting  schedule (i.e., the vesting schedule
          includes a vested  percentage that is more than 0% and less than 100%)
          the following will apply:

                 Years of vesting service      Nonforfeitable percentage

                           2                               20%
                           3                               40%
                           4                               60%
                           5                               80%
                           6                              100%

          If the plan does not have a graded  vesting  schedule,  then  matching
          contributions will be nonforfeitable upon the completion of 3 years of
          vesting service.

          In lieu  of the  above  vesting  schedule,  the  employer  elects  the
          following schedule:
          a. [ ] 3 year cliff (a participant's accrued benefit derived from
                 employer matching contributions shall be nonforfeitable upon
                 the participant's completion of three years of vesting
                 service).
          b. [ ] 6 year graded schedule (20% after 2 years of vesting service
                 and an additional 20% for each year thereafter).
          c. [ ] Other (must be at least as liberal as a. or the b. above):

                 Years of vesting service      Nonforfeitable percentage

                          --------                      ---------%
                          --------                      ---------%
                          --------                      ---------%
                          --------                      ---------%
                          --------                      ---------%

         The vesting schedule set forth herein shall only apply to participants
         who complete an hour of service in a plan year beginning after December
         31, 2001, and, unless the option below is elected, shall apply to all
         matching contributions subject to a vesting schedule.
         d. [ ] The vesting schedule will only apply to matching contributions
                made in plan years beginning after December 31, 2001
                (the prior schedule will apply to matching contributions made
                in prior plan years).

2.2      Exclusion of Rollovers in Application of Involuntary Cash-out
         Provisions (for profit sharing and 401(k) plans only). If the plan is
         not subject to the qualified joint and survivor annuity rules and
         includes involuntary cash-out provisions, then unless one of the
         options below is elected, effective for distributions made after
         December 31, 2001, rollover contributions will be excluded in
         determining the value of the participant's nonforfeitable account
         balance for purposes of the plan's involuntary cash-out rules.
         a. [ ] Rollover contributions will not be excluded.
         b. [ ] Rollover contributions will be excluded only with respect to
                distributions made after ________________________.
                (Enter a date no earlier than December 31, 2001.)
         c. [ ] Rollover contributions will only be excluded with respect to
                participants who separated from service after ______________.
                (Enter a date. The date may be earlier than December 31, 2001.)

2.3      Suspension period of hardship distributions. If the plan provides for
         hardship distributions upon satisfaction of the safe harbor (deemed)
         standards as set forth in Treas. Reg. Section 1.401(k)-1(d)(2)(iv),
         then, unless the option below is elected, the suspension period
         following a hardship distribution shall only apply to hardship
         distributions made after December 31, 2001.
            [X] With regard to hardship distributions made during 2001, a
                participant shall be prohibited from making elective deferrals
                and employee contributions under this and all other plans until
                the later of January 1, 2002, or 6 months after receipt of the
                distribution.

2.4      Catch-up contributions (for 401(k) profit sharing plans only): The plan
         permits catch-up contributions (Article VI) unless the option below is
         elected.
            [ ] The plan does not permit catch-up contributions to be made.

                                   ARTICLE III
                        VESTING OF MATCHING CONTRIBUTIONS

3.1     Applicability. This Article shall apply to participants who complete an
        Hour of Service after December 31, 2001, with respect to accrued
        benefits derived from employer matching  contributions made in plan
        years beginning after December 31, 2001. Unless otherwise elected by
        the employer in Section 2.1 above, this Article shall also apply to all
        such participants with respect to accrued  benefits derived from
        employer matching contributions made in plan years beginning prior to
        January 1, 2002.

3.2      Vesting  schedule.  A participant's  accrued benefit derived from
         employer matching contributions  shall vest as provided in Section 2.1
         of this amendment.

                                   ARTICLE IV
                              INVOLUNTARY CASH-OUTS

4.1      Applicability and effective date. If the plan provides for involuntary
         cash-outs of amounts less than $5,000, then unless otherwise elected in
         Section 2.2 of this amendment, this Article shall apply for
         distributions made after December 31, 2001, and shall apply to all
         participants. However, regardless of the preceding, this Article shall
         not apply if the plan is subject to the qualified joint and survivor
         annuity requirements of Sections 401(a)(11) and 417 of the Code.

4.2      Rollovers disregarded in determining value of account balance for
         involuntary distributions. For purposes of the Sections of the plan
         that provide for the involuntary distribution of vested accrued
         benefits of $5,000 or less, the value of a participant's nonforfeitable
         account balance shall be determined without regard to that portion of
         the account balance that is attributable to rollover contributions (and
         earnings allocable thereto) within the meaning of Sections 402(c),
         403(a)(4), 403(b)(8), 408(d)(3)(A)(ii), and 457(e)(16) of the Code. If
         the value of the participant's nonforfeitable account balance as so
         determined is $5,000 or less, then the plan shall immediately
         distribute the participant's entire nonforfeitable account balance.

                                    ARTICLE V
                             HARDSHIP DISTRIBUTIONS

5.1      Applicability and effective date.  If the plan provides for hardship
         distributions upon satisfaction of the safe harbor (deemed) standards
         as set forth in Treas. Reg. Section  1.401(k)-1(d)(2)(iv), then this
         Article  shall apply for calendar years beginning after 2001.

5.2      Suspension period following hardship distribution. A participant who
         receives a distribution of elective deferrals after December 31, 2001,
         on account of hardship shall be prohibited from making elective
         deferrals and employee contributions under this and all other plans of
         the employer for 6 months after receipt of the distribution.
         Furthermore, if elected by the employer in Section 2.3 of this
         amendment, a participant who receives a distribution of elective
         deferrals in calendar year 2001 on account of hardship shall be
         prohibited from making elective deferrals and employee contributions
         under this and all other plans until the later of January 1, 2002, or 6
         months after receipt of the distribution.

                                   ARTICLE VI
                             CATCH-UP CONTRIBUTIONS

Catch-up  Contributions.  Unless  otherwise  elected  in  Section  2.4  of  this
amendment,  all employees who are eligible to make elective deferrals under this
plan and who have  attained  age 50 before  the close of the plan year  shall be
eligible to make catch-up  contributions  in accordance with, and subject to the
limitations  of, Section 414(v) of the Code. Such catch-up  contributions  shall
not  be  taken  into  account  for  purposes  of  the  provisions  of  the  plan
implementing  the required  limitations of Sections  402(g) and 415 of the Code.
The plan shall not be treated as failing to satisfy the  provisions  of the plan
implementing  the  requirements of Section  401(k)(3),  401(k)(11),  401(k)(12),
410(b),  or 416 of the Code,  as  applicable,  by  reason of the  making of such
catch-up contributions.

                                   ARTICLE VII
                         INCREASE IN COMPENSATION LIMIT

Increase in Compensation  Limit.  The annual  compensation  of each  participant
taken into account in determining  allocations for any plan year beginning after
December 31, 2001,  shall not exceed  $200,000,  as adjusted for  cost-of-living
increases  in  accordance  with  Section   401(a)(17)(B)  of  the  Code.  Annual
compensation means  compensation  during the plan year or such other consecutive
12-month period over which  compensation is otherwise  determined under the plan
(the  determination  period).  If this is a target benefit plan,  then except as
otherwise elected in Section 2.5 of this amendment,  for purposes of determining
benefit accruals in a plan year beginning after December 31, 2001,  compensation
for  any  prior  determination   period  shall  be  limited  to  $200,000.   The
cost-of-living  adjustment  in effect  for a  calendar  year  applies  to annual
compensation  for the  determination  period  that  begins  with or within  such
calendar year.

                                  ARTICLE VIII

loans to be made to  participants,  then  effective  for plan  loans  made after
December 31, 2001, plan provisions  prohibiting  loans to any  owner-employee or
shareholder-employee shall cease to apply.

                                   ARTICLE IX
              LIMITATIONS ON CONTRIBUTIONS (IRC SECTION 415 LIMITS)

9.1      Effective date. This Section shall be effective for limitation years
         beginning after December 31, 2001.

9.2      Maximum annual addition. Except to the extent permitted under Article
         VI of this amendment and Section 414(v) of the Code, if applicable, the
         annual addition that may be contributed or allocated to a participant's
         account under the plan for any limitation year shall not exceed the
         lesser of:

         a. $40,000, as adjusted for increases in the cost-of-living under
            Section 415(d) of the Code, or

         b. 100 percent of the participant's compensation, within the meaning
            of Section 415(c)(3) of the Code, for the limitation year.

         The  compensation  limit  referred  to in b.  shall  not  apply to any
         contribution  for  medical  benefits  after  separation  from  service
         (within the  meaning of Section  401(h) or Section  419A(f)(2)  of the
         Code) which is otherwise treated as an annual addition.

                                    ARTICLE X
                         MODIFICATION OF TOP-HEAVY RULES

10.1     Effective date. This Article shall apply for purposes of determining
         whether the plan is a top-heavy plan under Section 416(g) of the Code
         for plan years beginning after December 31, 2001, and whether the plan
         satisfies the minimum benefits requirements of Section 416(c) of the
         Code for such years. This Article amends the top-heavy provisions of
         the plan.

10.2     Determination of top-heavy status.

10.2.1   Key employee. Key employee means any employee or former employee
         (including any deceased employee) who at any time during the plan year
         that includes the determination date was an officer of the employer
         having annual compensation greater than $130,000 (as adjusted under
         Section 416(i)(1) of the Code for plan years beginning after December
         31, 2002), a 5-percent owner of the employer, or a 1-percent owner of
         the employer having annual compensation of more than $150,000. For this
         purpose, annual compensation means compensation within the meaning of
         Section 415(c)(3) of the Code. The determination of who is a key
         employee will be made in accordance with Section 416(i)(1) of the Code
         and the applicable regulations and other guidance of general
         applicability issued thereunder.

10.2.2   Determination of present values and amounts. This Section 10.2.2 shall
         apply for purposes of determining the present values of accrued
         benefits and the amounts of account balances of employees as of the
         determination date.

         a.       Distributions during year ending on the determination date.
                  The present values of accrued benefits and the amounts of
                  account balances of an employee as of the determination date
                  shall be increased by the distributions made with respect to
                  the employee under the plan and any plan aggregated with the
                  plan under Section 416(g)(2) of the Code during the 1-year
                  period ending on the determination date. The preceding
                  sentence shall also apply to distributions under a terminated
                  plan which, had it not been terminated, would have been
                  aggregated with the plan under Section 416(g)(2)(A)(i) of the
                  Code. In the case of a distribution made for a reason other
                  than separation from service, death, or disability, this
                  provision shall be applied by substituting "5-year period" for
                  "1-year period."

         b.       Employees not performing services during year ending on the
                  determination date. The accrued benefits and accounts of any
                  individual who has not performed services for the employer
                  during the 1-year period ending on the determination date
                  shall not be taken into account.

10.3     Minimum benefits.

10.3.1   Matching contributions. Employer matching contributions shall be taken
         into account for purposes of satisfying the minimum contribution
         requirements of Section 416(c)(2) of the Code and the plan. The
         preceding sentence shall apply with respect to matching contributions
         under the plan or, if the plan provides that the minimum contribution
         requirement shall be met in another plan, such other plan. Employer
         matching contributions that are used to satisfy the minimum
         contribution requirements shall be treated as matching contributions
         for purposes of the actual contribution percentage test and other
         requirements of Section 401(m) of the Code.

10.3.2   Contributions under other plans. The employer may provide, in an
         addendum to this amendment, that the minimum benefit requirement shall
         be met in another plan (including another plan that consists solely of
         a cash or deferred arrangement which meets the requirements of Section
         401(k)(12) of the Code and matching contributions with respect to which
         the requirements of Section 401(m)(11) of the Code are met). The
         addendum should include the name of the other plan, the minimum benefit
         that will be provided under such other plan, and the employees who will
         receive the minimum benefit under such other plan.

                                   ARTICLE XI
                                DIRECT ROLLOVERS

11.1     Effective date. This Article shall apply to distributions made after
         December 31, 2001.

11.2     Modification of definition of eligible retirement plan. For purposes of
         the direct rollover provisions of the plan, an eligible retirement plan
         shall also mean an annuity contract described in Section 403(b) of the
         Code and an eligible plan under Section 457(b) of the Code which is
         maintained by a state, political subdivision of a state, or any agency
         or instrumentality of a state or political subdivision of a state and
         which agrees to separately account for amounts transferred into such
         plan from this plan. The definition of eligible retirement plan shall
         also apply in the case of a distribution to a surviving spouse, or to a
         spouse or former spouse who is the alternate payee under a qualified
         domestic relation order, as defined in Section 414(p) of the Code.

11.3     Modification of definition of eligible rollover distribution to exclude
         hardship distributions. For purposes of the direct rollover provisions
         of the plan, any amount that is distributed on account of hardship
         shall not be an eligible rollover distribution and the distributee may
         not elect to have any portion of such a distribution paid directly to
         an eligible retirement plan.

11.4     Modification of definition of eligible rollover distribution to include
         after-tax employee contributions. For purposes of the direct rollover
         provisions in the plan, a portion of a distribution shall not fail to
         be an eligible rollover distribution merely because the portion
         consists of after-tax employee contributions which are not includible
         in gross income. However, such portion may be transferred only to an
         individual retirement account or annuity described in Section 408(a) or
         (b) of the Code, or to a qualified defined contribution plan described
         in Section 401(a) or 403(a) of the Code that agrees to separately
         account for amounts so transferred, including separately accounting for
         the portion of such distribution which is includible in gross income
         and the portion of such distribution which is not so includible.

                               ELECTIVE DEFERRALS

14.1     Elective Deferrals - Contribution Limitation. No participant shall be
         permitted to have elective deferrals made under this plan, or any other
         qualified plan maintained by the employer during any taxable year, in
         excess of the dollar limitation contained in Section 402(g) of the Code
         in effect for such taxable year, except to the extent permitted under
         Article VI of this amendment and Section 414(v) of the Code, if
         applicable.

14.2     Maximum Salary Reduction Contributions for SIMPLE plans. If this is a
         SIMPLE 401(k) plan, then except to the extent permitted under Article
         VI of this amendment and Section 414(v) of the Code, if applicable, the
         maximum salary reduction contribution that can be made to this plan is
         the amount determined under Section 408(p)(2)(A)(ii) of the Code for
         the calendar year.

                                   ARTICLE XV
                           SAFE HARBOR PLAN PROVISIONS

Modification of Top-Heavy  Rules.  The top-heavy  requirements of Section 416 of
the Code and the plan shall not apply in any year  beginning  after December 31,
2001, in which the plan consists solely of a cash or deferred  arrangement which
meets  the  requirements  of  Section   401(k)(12)  of  the  Code  and  matching
contributions  with respect to which the  requirements of Section  401(m)(11) of
the Code are met.

                                   ARTICLE XVI
                    DISTRIBUTION UPON SEVERANCE OF EMPLOYMENT

16.1     Effective date. This Article shall apply for distributions and
         transactions made after December 31, 2001, regardless of when the
         severance of employment occurred.

16.2     New distributable event. A participant's elective deferrals, qualified
         nonelective contributions, qualified matching contributions, and
         earnings attributable to these contributions shall be distributed on
         account of the participant's severance from employment. However, such a
         distribution shall be subject to the other provisions of the plan
         regarding distributions, other than provisions that require a
         separation from service before such amounts may be distributed.


This amendment has been executed this 6th day of March, 2004.

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,   or  known  or  unknown  risks  and
uncertainties can affect these forward-looking  statements.  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 in 2004.

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 ICs.  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 recent years, 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 two of our last  three  fiscal  years.  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

Our  previously   implemented   restructuring   plans  may  yield  unanticipated
consequences,  such as increased burden on our administrative,  operational, and
financial resources and increased 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  as a part of our
restructuring  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,  particularly if our business
experiences  significant  growth Also, the reduction in workforce related to our
restructuring  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 IC 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 manufactures 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 70% of our net revenue for the fiscal year ended
December  31,  2003 and 79% for the  first  quarter  of  2004.  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 difficulties in integrating foreign and outsourced operations

o political and economic instability

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 and soon in Brazil.  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, Brazil and Germany may adversely affect our investment in our
subsidiaries.

Protection of Intellectual Property

Data I/O 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.

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.  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.
