PART I


Item 1. Business

This Annual Report on Form 10-K and the documents incorporated herein by
reference contain forward-looking statements based on current expectations,
estimates and projections about Data I/O(R) Corporation's industry, management's
beliefs and certain assumptions made by management. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations - Forward Looking
Statements."

General

Data I/O Corporation ("Data I/O") designs, manufactures, and sells programming
systems used by designers and manufacturers of electronic products. Our
programming system products are used to program integrated circuits ("ICs" or
"devices" or "semiconductors") so that the ICs will function as desired in the
customer's electronic product. They are an important tool for the electronics
industry experiencing growing use of programmable ICs. Data I/O markets and
distributes our programming systems worldwide, and is a global leader in this
market. Data I/O incorporated in the State of Washington in 1969.

Data I/O Mission. Data I/O's mission is to design and deliver innovative
customer-focused programming solutions, which enable customers to manage their
firmware supply chain, getting their products to market faster, while reducing
costs in their process. We align our products and services to make programming
easy, delight our customers and satisfy their whole product needs.

Helping customers manage their firmware supply chain. Much of the innovation and
competitive advantage of today's electronic products comes from the software
embedded inside the product, which is commonly referred to as "firmware."
Companies use firmware to differentiate their products from their competitors'
products, constantly writing new code to add features. This allows them to build
multiple models with identical hardware and many versions of firmware, all on
one production line. Any improvement in production efficiency boosts the
profitability of all products on that line. Many original equipment
manufacturers ("OEMs") now outsource production to specialists in electronic
manufacturing services ("EMS") to maximize the profit impact from highly
efficient production. The challenges of managing the firmware supply chain
remain, however, and can even increase with this additional interface. Our
systems allow our customers - both OEM and EMS companies - to build products
with the exact firmware features that consumers specify, virtually real-time
with the latest software release. We help our customers eliminate inventory
risks, delays, rework, and lost market opportunities while enabling them to
better serve their customers.

Connected Strategy. Data I/O's connected strategy leverages network capable
products to move the customer's intellectual property seamlessly and securely up
and down the supply chain. Our connected strategy allows customers to connect
engineering to manufacturing to end customers.

Business Restructuring. During 2003, we completed the restructuring process,
which began in 2001. We took restructuring charges in 2001 and 2002 that were
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 over the past few years. We believe these actions made
possible our turnaround and profitable operations in 2003. At the end of 2003
our breakeven point was approximately $6.2 million in net sales with 127
employees worldwide. Our breakeven point increased in 2003 primarily due to cost
increases resulting from the impact of the weaker dollar on foreign currency
based costs and from personnel costs due to salary increases, incentive
compensation and selective hiring of individuals with critical skills to help
position us as the continuing technology leader in our market.

During 2002, we reduced our quarterly breakeven point from approximately $7
million of net sales at the beginning of 2002 to approximately $5.7 million at
the end of 2002. We achieved most of these reductions by reducing our personnel
from 155 at the beginning of 2002 to 125 at the end of 2002.

During 2001, we took a number of strategic restructuring actions to reduce our
breakeven point. Repositioning included the following: a reduction in our global
workforce from 224 at the start of the year to 155 at the end of 2001;
discontinuance or reallocation of numerous projects and activities not essential
to our long-term goals; streamlining activities to decrease discretionary
marketing, distribution and promotional expenses, consolidation of numerous
functions across the organization to create a team, which was more productive
and able to respond faster to global customer needs; and closure of a facility
in Germany and moving its operations to other locations within Data I/O.

At December 31, 2003 all restructuring expenses associated with the activities
detailed above were paid and the excess restructure accrual of $39,000 had been
reversed.

Industry Background

Data I/O operates in a niche of the electronics equipment industry that provides
programming systems used to load specific data and design information into
programmable devices. Companies that design and manufacture electronic products
that utilize programmable devices purchase these systems from us. These
companies, our primary customers, design and manufacture a broad range of
electronic products for both consumer and industrial use.

Programmable devices represent an over $10 billion segment of the semiconductor
industry, and have grown more rapidly than the semiconductor industry as a whole
in recent years. Flash memory, NAND-Flash, and programmable micro-controllers
are typical of these devices. Programmable devices offer advantages to the
electronic product designer allowing them to bring products to market more
quickly and inexpensively than using fixed-function devices, and can offer the
advantage of simpler rapid product upgrades. Programmable devices also offer
attractive functionality to the user of the electronic product, such as storing
personal information or customizing product functionality. As a result, use of
programmable devices is growing rapidly in both high-volume consumer electronic
products and more complex electronic systems.

Due to this growth, more than 100 semiconductor manufacturers offer thousands of
different programmable devices. The technology trends driving the programmable
device market result in a broad range of requirements for programming
information into these devices. Programmable memory devices continue to have
higher capacity and occupy smaller circuit board space. Programmable
microcontroller devices are now more prevalent because semiconductor vendors are
standardizing their manufacturing processes. These technology advances require
advanced programming equipment like Data I/O manufactures.

Our automated programming systems integrate programming and handling functions
into one product for increasing handling and programming capacity. Quality
conscious customers continue to drive this portion of our business, which
includes high-volume manufacturing and high-volume programming center customers.

Products

In order to accommodate the expanding variety and quantities of programmable
devices being manufactured today, Data I/O offers multiple solutions for the
numerous types of devices used by our customers in the various market segments
and applications. We work closely with major manufacturers of programmable
devices to develop our products to meet the requirements of a particular device.

Data I/O's line of programming systems includes a broad range of products,
systems, modules, and accessories, which we group into two general categories:
automated programming systems and non-automated programming systems. We provide
automated programming systems in two categories: off-line and in-line. In
addition, we provide device support and service on all of our products. Device
support is a critical aspect of our business and consists of writing algorithms
for devices and developing socket adapters to hold and connect to the device for
programming.

Within the categories of automated and non-automated systems, Data I/O targets
specific solutions at specific market segments. Data I/O optimizes the solution
based on the customer's device, process and business needs. We think the market
growth opportunity is not a relatively costly universal solution with very broad
device support, but optimized systems focused on a narrower range of devices
(such as Flash devices), which provide customers with the economical programming
solutions for high volumes of devices and lean processes. Our recent product
introductions have focused on these growth markets and targeted their specific
needs.

TaskLink(R) is our software platform that provides a common intuitive user
interface and enhances the quality of the customer's programming process. As
part of our core technology, TaskLink also supports Data I/O's connected
strategy, allowing customers to connect engineering to manufacturing to end
customers.

Automated Programming Systems

Data I/O provides our manufacturing and programming center customers with
automated programming systems solutions that include robotic handlers, a variety
of programmers, input and output media handling (such as tray stackers, tubes,
loaders or taping), and marking solutions. Our ProLINE-RoadRunner(TM) is a
unique in-line programming system with programming speed capability, which
approaches the speed at which Flash devices can currently accept data. Many of
our customers need to program Flash and microcontroller devices in large
quantities and very quickly. ProLINE-RoadRunner mounts directly on the assembly
machine in the production line (Siemens, Fuji, Universal, Panasonic and
Assembleon machines) and delivers programmed parts from reels of blank devices
to the production line in a just-in-time fashion. Our ProLINE-RoadRunner
eliminates production bottlenecks associated with high-density Flash and
microcontroller devices, allowing last minute firmware changes and eliminating
programmed part inventories, ultimately streamlining and reducing the customer's
production and process costs. ProLINE-RoadRunner enables customers to implement
lean processes and is a key element in Data I/O's connected strategy, allowing
customers and partners to more effectively manage their firmware supply chain.
ProLINE-RoadRunner currently retails from $60,000 to $95,000, depending on
programming capability. We continue to leverage our ProLINE-RoadRunner in our
platform to reach a broader market, which during 2003 included focusing on the
FlashCORE(TM) architecture by expanding its capability to address newer
technologies like NAND Flash support for M-Systems DiskOnChip(R) technology.

Data I/O's PS family of automated programming solutions offers highly flexible
solutions for off-line batch programming. Data I/O can configure PS systems to
support not only Flash devices, but also a wide variety of other devices, such
as microcontrollers. These systems provide a number of marking, labeling, and
input/output options. Most importantly, customers can make changeovers extremely
fast. This feature allows the customer to rapidly respond to diverse demands
with very little downtime. Customers can optimize the PS family systems for any
job to maximize throughput and, when combined with fast changeover times and
high reliability, provide the highest levels of output during a production
shift. Our latest product, the PS288, integrates the same FlashCORE programmer
we use in our PS300 FlashCORE, ProLINE-RoadRunner and FlashPAK(TM) and builds on
our connected strategy and common architecture. For smaller memory,
microcontroller and logic devices, our ProMaster systems offer a cost-effective,
high-yield automated solution. Prices for our off-line systems range from
$50,000 to $500,000, with an average configuration selling between
$200,000-$300,000.

Non-Automated Programming Systems

Our line of non-automated programming systems provides solutions for both
engineering and low to medium-volume manufacturing customers. Non-automated
programming systems require a user to physically handle the devices being
programmed. These types of programmers are also sometimes referred to as
"manual" or "desktop" programmers. We now have three families of non-automated
programmers: Sprint, UniSystem and FlashPAK.

Engineering customers typically use single-site programming systems during the
prototype phase of a new design, and may purchase inexpensive systems for
limited device needs or more expensive systems to support more complex devices
or a large variety of device types. Single-site programming systems can perform
programming on only one programmable device at a time.

Data I/O offers a range of high quality, universal single socket manual
programming solutions through our UniSystem family of programming systems. Our
UniSite and 3980 xpi programming systems offer the highest levels of signal
integrity, which ensure the highest programming standards. Popular in military,
aerospace, telecommunications and other mission critical applications, the
systems range from $11,000 to $35,000.

For more cost constrained or higher volume applications, the Sprint family of
products offers excellent value for the money and versatility. The Sprint Quad
and Octal programming systems offer 4 and 8 socket universal programming
configurations for the higher volume applications. These two families of
products range in price from under $1,000 to $16,000 for the multiple socket
solutions.

Our newest programmer, the FlashPAK, leverages the high-speed proprietary
FlashCORE programming technology in the ProLINE-RoadRunner system. We believe
FlashPAK, priced at $6,000, is the world's fastest programming architecture,
limited today only by the speed at which Flash devices can accept data. FlashPAK
is another key element of Data I/O's connected strategy, providing OEMs and new
product introduction facilities with a high performance Flash programming system
that can be used to validate designs before moving down the firmware supply
chain. For manufacturing applications, the FlashPAK, a high speed, multi-socket,
small footprint desktop solution, provides manual programming operations with
the highest level of flexibility at the lowest cost per part. Manufacturers that
use manual programming because of lower labor costs in areas like Asia find
FlashPAK an attractive solution.

Data I/O supports and completes our product offering with a full range of
software and device update products and worldwide service and repair capability.

Customers

Data I/O sells our products to customers worldwide in a broad range of
industries, including wireless handset manufacturers and other telecommunication
companies, consumer electronics, computers, test and measurement, medical,
transportation, military, aerospace, electronic contract manufacturing, and
semiconductors. Our principal customers include Motorola, Nokia, and Siemens.
Our customers either design and/or manufacture electronic products that
incorporate programmable



devices or provide device programming services. During 2003, we sold products to
over 2,000 customers throughout the world, and one customer accounted for 18% of
our net sales and no others accounted for over 10%.

Programmable device consumption continues to grow as more and more electronic
product manufacturers take advantage of the flexibility and cost effectiveness
of programmable memory, microcontroller and logic devices. Electronic products
today utilize programmable technology in one form or another, from
microcontrolled home appliance devices to set top boxes and wireless devices,
which use increasingly vast amounts of memory for Internet connectivity and new
leading edge features. Therefore, our customers come from virtually all
industries manufacturing electronic products, and include the consumer
electronic products, cell phone, personal data assistants ("PDAs") and other
wireless device manufacturers, home entertainment product sectors, aerospace and
military applications, the personal computer ("PC") and PC peripheral industry
and automotive electronics.

Flash memory growth. The Flash memory customer segment is experiencing some of
the most impressive growth of all programmable devices. As cell phones, PDAs,
games consoles, set top boxes and other consumer devices become more capable,
powerful and compact, the demand for Flash units and megabytes continues to
grow.

Microcontroller growth. As the demand for smarter electronic devices increases,
demand for greater numbers of microcontroller devices increases. Many household
appliances today contain a microcontroller to control the critical functions of
the product and provide new features. Examples of these appliances include
toasters, refrigerators, garage door openers and even thermostats. This growth
creates new market opportunities for us and we have added support for these
devices in our FlashCORE architecture. In addition, the number of
microcontrollers in automotive electronic applications is growing rapidly, with
some cars having as many as 80 or more microcontrollers that control functions
from airbag and ABS systems to air conditioning, information centers and
entertainment and communication systems. We are also targeting the automotive
segment as a critical and growing target segment for our solutions.

Geographic Markets and Distribution

Data I/O markets and sells our products through a combination of direct sales,
internal telesales, and indirect sales representatives and distributors. We
continually evaluate our sales channels against our evolving markets and
customers.

U.S. Sales

We market our products throughout the U.S. using a variety of sales channels,
including our own field sales management personnel, independent sales
representatives, and a direct telesales organization. Our U.S. independent sales
representatives obtain orders on an agency basis, with shipments made directly
to the customer by Data I/O. 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. Net Sales in
the United States for 2003, 2002 and 2001 were $7,263,000, $8,347,000 and
$9,526,000, respectively.

Foreign Sales

Foreign sales represented approximately 70%, 63% and 64% of net sales of our
programming systems in 2003, 2002 and 2001, respectively (see Note 15 of "Notes
to Consolidated Financial Statements"). We make foreign sales through our
wholly-owned subsidiaries in Germany, China and Canada, as well as through
independent distributors and sales representatives located in 35 other
countries. We record sales made through foreign subsidiaries requiring
installation by Data I/O that is other than perfunctory 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 recognize it on a
straight-line basis over the contractual period. Our independent foreign
distributors purchase Data I/O products in U.S. Dollars for resale and we
recognize the sale at the time of shipment to the distributor. As with U.S.
sales representatives, sales made by international sales representatives are on
an agency basis with shipments made directly to the customer by us. We recognize
sales, denominated in U.S. Dollars, upon shipment, if installation is
perfunctory or does not need to be performed by us, or when the equipment is
installed at the end-user's site, if installation is more than perfunctory and
is to be performed by us, or in the case where acceptance is required, upon
acceptance.

Net foreign sales for 2003, 2002 and 2001 were $17,424,000, $14,491,000 and
$17,300,000, respectively. We determine total foreign sales by the international
geographic area into which the products are sold and delivered, and include not
only sales by foreign subsidiaries but also export sales from the U.S. to our
foreign distributors and to our representatives' customers. Foreign sales do not
include transfers between Data I/O and our foreign subsidiaries. Export sales
are subject to U.S. Department of Commerce regulations. We have not, however,
experienced any difficulties to date as a result of these requirements.

Fluctuating exchange rates and other factors beyond our control, such as
international monetary stability, tariff and trade policies, and U.S. and
foreign tax and economic policies, affect the level and profitability of foreign
sales. We cannot predict the effect of such factors on our business.

Competition

The competition in the programming systems market is highly fragmented with a
large number of smaller organizations offering inexpensive solutions. We
estimate that prior to the past couple years the total number of programming
systems sold each year has been less than $150 million, with Data I/O capturing
an estimated 20 to 25% of the global market. Over the last three years, we
believe the amount has declined by about 50% and that Data I/O has gained market
share versus our significant competitors.

Competitive factors often include prices, features, device support and
programming speed, as the programming process impacts more on the major
manufacturers' total production process. However, competitive factors are
changing. The added value for customers is becoming the whole product solution
that fits the customer's required process. As an example, ProLINE-RoadRunner
offers a unique solution, which best addresses the customer's process needs in
high volume Flash applications. To this extent, the value proposition of this
specific programming solution is very different from traditional solutions.

Therefore, addressing customers' process needs is critical to increasing the
opportunity for programming solutions beyond the current amount in this market
niche. We estimate that customers are spending between $1 to $2 billion a year
on programming memory, microcontroller and logic devices and much of this
programming is achieved through the use of the customers' test equipment offered
by companies like Agilent and Teradyne or homegrown solutions for specific
markets like automotive. The main competitive solution in the programmable
market is, therefore, the in-house solution, and the opportunity exists to
substitute customers' solutions with more economical and more easily
maintainable solutions to solve the problems, which traditional programmers do
not address. Boundary scan tools also fall into this category, although still a
very small market with a number of small companies participating who principally
focus on test solutions. A number of companies are part of a trend towards using
in-system programming, which Data I/O does not currently address but continues
to evaluate.

Manufacturing, Raw Materials, and Backlog

Data I/O performs primarily assembly and testing of our products at our
principal facility in Redmond, Washington and we outsource our circuit board
manufacturing and fabrication. We use a combination of standard components,
proprietary custom ICs and fabricated parts manufactured to Data I/O
specifications. An outside supplier located in Germany manufactures our Sprint
non-automated programming systems. Most components used are available from a
number of different suppliers and subcontractors but certain items, such as some
handler and programmer subassemblies, custom ICs, hybrid circuits and
connectors, are purchased from single sources. We believe that additional
sources can be developed for present single-source components without
significant difficulties in obtaining supplies. We cannot be sure that
single-source components will always continue to be readily available. If we
cannot develop alternative sources for these components, or if we experience
deterioration in relationships with these suppliers, there may be delays or
reductions in product introductions or shipments, which may materially adversely
affect our operating results.

In accordance with industry practices, generally all orders are subject to
cancellation prior to shipment without penalty, except for contracts calling for
custom configuration. To date, such cancellations have not had a material effect
on our sales volume. To meet customers' delivery requirements, we manufacture
certain products based upon a combination of backlog and anticipated orders.
Most orders are scheduled for delivery within 1 to 60 days after receipt of the
order. Our backlog of pending orders was approximately $1.5 million, $1.3
million and $1.9 million as of December 31, 2003, 2002 and 2001, respectively.
The size of backlog at any particular date is not necessarily a meaningful
indicator of the trend of our business.

Research and Development

Data I/O believes that continued investment in research and development is
critical to our future success. We continue to develop new technologies and
products and enhance existing products. Future growth is to a large extent
dependent upon the timely development and introduction of new products, as well
as the development of algorithms to support the latest programmable devices. We
are currently focusing our research and development efforts on strategic growth
markets, namely new programming technology and automated handling systems for
the manufacturing environment, including support for NAND FLASH and for
M-Systems DiskOnChip(R) technology, microcontroller support for FlashCORE and
additional platforms and improvements for ProLINE-RoadRunner. We continue to
also focus on increasing our capacity and responsiveness for new device support
requests from customers and programmable IC manufacturers by revising and
enhancing our internal processes and tools. During this past year, our research
and development resulted in these new products: PS300, PS288, and the TF-30 Tray
Feeder and extensions of ProLINE-RoadRunner.

During 2003, 2002 and 2001, we made expenditures for research and development of
$4,639,000, $5,331,000 and $6,740,000, respectively, representing 18.8%, 23.3%
and 25.1% of net sales, respectively. Research and development costs are
expensed as incurred.

Patents, Copyrights, Trademarks, and Licenses

Intellectual property rights applicable to various Data I/O products include
patents, copyrights, trade secrets and trademarks. 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 also grew our patent portfolio over the past few
years as we developed strategic technologies like the ProLINE-RoadRunner and
FlashCORE that are critical to our connected strategy.

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 not
normally sold separately from sales of programming systems. However, on those
occasions where software is sold separately, revenue is recognized when a sales
agreement exists, when delivery has occurred, when the fee is fixed or
determinable, and when collectibility is probable.

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.

Employees

As of December 31, 2003, we had 127 employees, of which 31 were located outside
the U.S. 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.

Environmental Compliance

Our facilities are subject to numerous laws and regulations concerning the
discharge of materials or otherwise relating to the environment. Compliance with
environmental laws has not had, nor is it expected to have, a material effect on
our capital expenditures, financial position, results of operations or
competitive position.

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 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 2003 and the past few 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 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. 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 costs 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 Data I/O's Common Stock
("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. We expect that international sales will continue to be a
significant portion of our net revenue. International sales and operations may
fluctuate due to various factors, including:

o migration of manufacturing to low cost geographies

o regulatory requirements and any changes to these 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. 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

Refer to the section "Patents, Copyrights, Trademarks and Licenses" in Item 1
above.

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

Refer to the section "Employees" 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.

Item 2. Properties

In May 1997, Data I/O completed the sale of the land and building comprising our
Redmond, Washington corporate headquarters and it is currently leasing the
96,000 square foot building on a 10-year leaseback agreement with an option to
renew the lease for an additional 10 years. This lease required base annual
rental payments in 2003 of approximately $1,138,000. See Note 6 of "Notes to
Consolidated Financial Statements." As part of our 1999 restructuring plan
implementation, we vacated one floor of the leased Redmond facility
(approximately 25,000 square feet) and sublet the majority of this space for a
period of 28 months beginning January 1, 2000, at a rate of approximately
$33,000 per month through April 2002. The sublease terminated in June 2002. We
have not been successful in subleasing this space and believe the market for
this space is currently quite limited.

In addition to the Redmond facility, approximately 9,000 square feet is leased
at five foreign locations, including our Canadian sales and service office
located in Mississauga, Ontario, German sales, service and engineering
operations located in Munich, Germany, and three sales and service offices in
China.

Item 3. Legal Proceedings

As of the date of this Annual Report, Data I/O is not a party to any legal
proceedings, the adverse outcome of which in management's opinion, individually
or in the aggregate, would have a material adverse effect on our results of
operations or financial position. From time to time, we may be involved in
litigation relating to claims arising out of our operations in the normal course
of business.

Item 4. Submission of Matters to a Vote of Shareholders

No matters were submitted for a vote of shareholders of Data I/O during the
fourth quarter of the fiscal year ended December 31, 2003.

Forward-Looking Statements

This Annual Report on Form 10-K 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 Annual Report on Form 10-K are forward-looking. In particular,
statements herein regarding industry prospects and trends; future results of
operations or financial position; integration of acquired products and
operations; market acceptance of our newly introduced or upgraded products;
development, introduction and shipment of new products; establishing foreign
operations; 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 Annual Report. The Reader should not place
undue reliance on these forward-looking statements. The following discussions
and the section entitled "Business - Cautionary Factors That May Affect Future
Results" describes some, but not all, of the factors that could cause these
differences.

OVERVIEW

In 2003, our primary goal was to manage the business to achieve profitable
operations, while developing and enhancing products to drive revenue and
earnings growth. Our challenge continued to be the weak and uncertain economic
environment with its limited capacity related demand and weak capital spending.
We expect that demand for capacity should improve, based on forecasted increased
unit sales for the semiconductor industry, which should provide improved
business opportunities for Data I/O.

The restructuring actions that were initiated in 2001 and continued in 2002 were
completed in 2003. This brought our quarterly breakeven point down below the
level of net sales that we were experiencing in 2003, resulting in our
turnaround and profitability. 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 the combination of our newer products with the NAND
Flash and microcontroller support to gain new accounts and break into new
markets, such as microcontrollers for the automotive market. We are in the
process of setting up a new subsidiary in China, expanding our China operations
to take advantage of the growth of manufacturing in China. We also increased our
efforts in 2003 to partner with the semiconductor manufacturers to better serve
our mutual customers.

BUSINESS RESTRUCTURING PROGRESS

During 2003, we completed the restructuring that began during 2001, which
included 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 over
the past few years. At the end of 2003, our quarterly breakeven point was
approximately $6.2 million in net sales with 127 employees worldwide. Our
breakeven point increased in 2003, primarily due to cost increases resulting
from the impact of the weaker dollar on foreign currency based costs and from
personnel costs due to salary increases, incentive compensation and selective
hiring of individuals with critical skills to help position us as the continuing
technology leader in our market.

During 2002, we recorded restructuring charges of $632,000 in connection with
our actions to reduce our quarterly breakeven point from approximately $7
million of net sales at the beginning of 2002 to approximately $5.7 million at
the end of 2002. We achieved most of these reductions by reducing our personnel
from 155 at the beginning of 2002 to 125 at the end of 2002.

During 2001, we recorded restructuring charges of $1,211,000 in connection with
a number of strategic restructuring actions to reduce our breakeven point. This
restructuring included the following: a reduction in our global workforce from
224 at the start of the year to 155 at the end of 2001; discontinuance or
reallocation of numerous projects and activities not essential to our long-term
goals; streamlining activities to decrease discretionary marketing, distribution
and promotional expenses, consolidation of numerous functions across the
organization to create a team, which was more productive and able to respond
faster to global customer needs; and closure of a facility in Germany and moving
our operations to other locations within Data I/O.

At December 31, 2003 all restructuring expenses associated with the activities
detailed above had been paid and the excess expense accrual of $39,000 was
reversed during 2003.

CRITICAL ACCOUNTING POLICY JUDGMENTS AND ESTIMATES

The preparation of financial statements in accordance with accounting principles
generally accepted in the United States of America 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, Data I/O evaluates 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.

Data I/O believes 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, Data I/O may
be required to increase our inventory provision adjustments and our gross margin
could be adversely affected.

Warranty Accruals: Data I/O accrues 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.

2003 vs. 2002
Data I/O experienced a turnaround in sales during 2003, with a resurgence in
sales of automated system products. In particular, automated systems aftermarket
products and PS 300 FlashCORE and related upgrades, which were new in 2003,
drove the sales growth. Our non-automated systems continued a trend of declining
sales in older products; however, FlashPAK, which was new in 2002, grew 360% in
2003, partially offsetting the decline. Also contributing to the non-automated
system decline was the loss of a low cost programmer line. ICE Technology, our
former supplier of the line, ceased business. In 2003, sales related to the Ice
Technology products were approximately $50,000, compared to $250,000 in 2002.

International sales grew, particularly in Europe, while sales in the U.S. market
continued to decline. The U.S. dollar continued to weaken in 2003, which we
believe assisted our export sales, due to increased buying power of foreign
currencies and the favorable effect of currency translation for sales
denominated in foreign currency, and in particular the Euro. We see a continuing
trend in migration of customers moving manufacturing operations to low-cost
geographies, thereby increasing international sales opportunities. The weakened
U.S. dollar, especially compared to the Euro, is expected to continue to assist
our export sales.

We are continuing the transition to a common programming architecture for all of
our products. This allows us to consolidate device support on a single platform
and provides substantial cost benefits to Data I/O. The recently introduced PS
288 FlashCORE automated programming system incorporates this common
architecture. In 2003, we also introduced NAND and microcontroller support
FlashCORE architecture, the TF-30 Tray Feeder System, and a version of our
ProLINE-RoadRunner designed for Panasonic machines. We expect these products to
increase our revenues; however, partially offsetting this increase is the trend
of declining sales of our older product lines.

2002 vs. 2001
Data I/O sales declined for the year 2002 compared to 2001. However, for the
third and fourth quarters of 2002, sales increased over the same quarters in
2001. We attribute the overall decline to the continued economic downturn,
especially in capital spending. Sales declined in all product categories, but
the declines were offset in part by increased sales from our ProLINE-RoadRunner
and new FlashPAK product lines. Sales declined in both in the US and
international markets with the Americas and Europe declining the most.

Gross Margin



(in thousands) 2003 Change 2002 Change 2001
- -----------------------------------------------------------------------------------------------------------------------------

Gross margin $13,679 21.2% $11,282 (4.0%) $11,748
Percentage of net sales 55.4% 49.4% 43.8%
- -----------------------------------------------------------------------------------------------------------------------------


2003 vs. 2002
Gross margins increased in both dollars and as a percentage of sales for 2003
compared to 2002. The increase in gross margin dollars was due to both the
increase in revenue dollars as well as the savings related to our restructuring
actions. The restructuring efforts lowered our annual breakeven point by
implementing cost reductions as well as lowering inventory reserve charges
compared to 2002. The continued product mix shift towards higher margin
automated systems aftermarket continued to be a favorable factor in 2003.

2002 vs. 2001
Gross margin decreased in dollars due primarily to the decline in sales volume.
Gross margin increased as a percentage of sales primarily due to the savings
from the restructuring and implementation of cost reductions, as well as lower
inventory reserve and warranty charges. The product mix towards additional
ProLINE-RoadRunner and related aftermarket products also improved the gross
margin as a percentage of sales. The restructuring efforts lowered our breakeven
point by bringing cost and operation expenditures, primarily personnel
reductions, in line with the revenue levels we experienced at the end of 2002.

Research and Development

Percentage of net sales 18.8% 23.3% 25.1%
- -----------------------------------------------------------------------------------------------------------------------------


2003 vs. 2002
Research and development ("R&D") spending for 2003 as compared to 2002 declined
both in dollars and as a percentage of sales. This was again due to the
restructuring actions, primarily personnel reductions and cost control efforts
taken over the past two years. During 2003, Data I/O's R&D focused on the
FlashCORE architecture, expanding its capability to address newer technologies
like NAND Flash support for M-Systems DiskOnChip technology as well as
microcontroller device support. New products in the PS family of automated
systems included the PS 300 FlashCORE, the TF-30 Tray Feeder system and,
introduced in early 2004, the PS 288 FlashCORE. Also, we released a
ProLINE-RoadRunner version for Panasonic machines.

2002 vs. 2001
R&D spending for 2002 as compared to 2001 declined both in dollars and as a
percentage of sales. This was due primarily to the lower headcount related to
our restructuring actions during 2001 and 2002. During 2002, Data I/O's R&D
focused on the new FlashPAK gang programming system and PS300 FlashCORE
automated programming system, which integrated the programming architecture
first introduced in the ProLINE-RoadRunner. We also released the following new
products: ProLINE Infinity, a ProLINE-RoadRunner utilizing an automated handler;
ProLINE-RoadRunner Variable Capacity Options; TF-20 Tray Feeder System; and High
Insertion Socket Adapters.

We believe it is essential to invest in R&D to significantly enhance our
existing products and to create new products as markets develop and technologies
change. We are focusing our R&D 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. In 2004, we expect to
add personnel and project related costs, so R&D spending is expected to increase
in 2004.

Percentage of net sales 31.5% 36.1% 36.2%
- ----------------------------------------------------------------------------------------------------------------------------


2003 vs. 2002
Selling, General and Administrative ("SG&A") expenses decreased by $474,000 in
2003 versus the prior year due primarily to the restructuring actions and
reduced marketing expenses. Partially offsetting this decrease was our increased
facility costs due to increased rent and loss of a sub-tenant; profit-based
bonuses; and increased selling costs due to currency translation with the weaker
US dollar and commissions.

2002 vs. 2001
SG&A spending decreased by $1.5 million in 2002 versus the prior year due
primarily to the restructuring actions. We reduced our expense by lowering our
bad debts reserve due to collection of accounts receivable, incurring less
retirement plan costs and lower commissions, partially offsetting these
reductions were higher rent and insurance costs.



Interest

Interest expense ($23) 27.8% ($18) 12.5% ($16)
- ----------------------------------------------------------------------------------------------------------------------------


2003 vs. 2001
Interest income for 2003 increased as compared to 2002 primarily due to the
increase in cash, cash equivalents and marketable securities.

2002 vs. 2001
Interest income for 2002 decreased as compared to 2001 primarily due to the
reduction in interest rates that occurred during 2002 and 2001.

Income Taxes



(in thousands) 2003 2002 2001

Income tax expense (benefit) $33 ($61) $224
- ----------------------------------------------------------------------------------------------------------------------------


2003 vs. 2002 and 2002 vs. 2001
Income tax expense in all years relates to foreign income taxes. For financial
reporting purposes, Data I/O established tax valuation reserves against our
deferred tax assets because of the uncertainty relating to the realization of
such asset values. We had valuation allowances of $9.7 million, $10.1 million
and $9.0 million at December 31, 2003, 2002 and 2001, respectively.

Inflation and changes in Foreign currency exchange rates

Sales and expenses incurred by foreign subsidiaries are denominated in the
subsidiary's local currency and translated into U.S. Dollar amounts at average
rates of exchange during the year. We recognized foreign currency transaction
losses of $81,000, $150,000 and $222,000 in 2003, 2002 and 2001, respectively.
The transaction losses resulted primarily from sales by our German subsidiary to
our main customers, which were invoiced in US dollars. We hedge our foreign
currency exposure on sales of inventory and certain loans to our foreign
subsidiaries through the use of foreign exchange contracts. See Note 1 of "Notes
to Consolidated Financial Statements."

Financial Condition

Liquidity and Capital Resources



(in thousands) 2003 Change 2002 Change 2001
- ----------------------------------------------------------------------------------------------------------------------------

Working capital $11,032 $1,907 $9,125 $(2,885) $12,010
- ----------------------------------------------------------------------------------------------------------------------------


In 2003, cash and marketable securities increased by $1,275,000, primarily
resulting from funds generated by operations. Key elements of working capital
changes reflected the increase in business: inventories increased by $131,000;
accounts receivable increased by $726,000; and accounts payable and accrued
expenses together increased $274,000. The increase in accounts receivable also
reflects the longer collection period typically associated with international
sales.

We estimate that capital expenditures for property, plant and equipment during
2004 are planned to be approximately $700,000. Although we expect to make such
expenditures, we had no significant outstanding purchase commitments at December
31, 2003. Such expenditures are expected to be funded by existing and internally
generated funds or lease financing.

As a result of our significant product development, customer support, and
selling and marketing efforts, Data I/O has required substantial working capital
to fund our operations. Over the last few years, we restructured our operations
to lower our costs and operating expenditures to lower our breakeven point,
preserve our cash position and return to profitable operations, as reflected in
our 2003 results. We believe that we have sufficient working capital available
under our operating plan to fund our operations and capital requirements through
at least December 31, 2004. Any substantial inability to achieve our current
business plan could have a material adverse impact on our financial position,
liquidity, or results of operations and may require us to reduce expenditures
and/or seek additional financing.




Aggregate Contractual Obligations and Commitments

Data I/O has purchase obligations for inventory and production costs as well as
other obligations such as capital expenditures, service contracts, marketing,
and development agreements. Arrangements are considered purchase obligations if
a contract specifies all significant terms, including fixed or minimum
quantities to be purchased, a pricing structure and approximate timing of the
transaction. Most arrangements are cancelable without a significant penalty, and
with short notice, typically less than 90 days. Any amounts reflected on the
balance sheet as accounts payable and accrued liabilities are excluded from the
table below. Data I/O has no long-term debt. Data I/O has commitments under
non-cancelable operating leases and other agreements, primarily for factory and
office space, with initial or remaining terms of one year or more as follows:

Share repurchase program

Under a previously announced share repurchase program, Data I/O is authorized to
repurchase up to 1,123,800 shares of our outstanding Common Stock. We may
execute these purchases through open market purchases at prevailing market
prices, through block purchases or in privately negotiated transactions, and we
may commence or discontinue at any time. As of December 31, 2003, Data I/O has
repurchased 1,016,200 shares under this repurchase program at a total cost of
approximately $7.1 million. Data I/O has not repurchased shares under this plan
since the second quarter of 1997, although it still has the authority to do so.

NEW ACCOUNTING PRONOUNCEMENTS

During 2001, the Financial Accounting Standards Board (FASB) issued Statement of
Financial Accounting Standards (SFAS) No. 143 "Accounting for Asset Retirement
Obligations" and, during 2002, the FASB issued SFAS No. 146, "Accounting for
Costs Associated with Exit and Disposal Activities". The adoption of SFAS Nos.
143 and 146 during fiscal 2003 did not have a material impact on our
consolidated financial statements.

In November 2002, the Emerging Issues Task Force (EITF) released Issue No.
02-16, "Accounting by a Customer (including a Reseller) for Certain
Consideration Received from a Vendor", applicable to Data I/O for arrangements
entered into beginning in fiscal 2003. Data I/O records vendor allowances and
discounts in the income statement when the purpose for which those monies were
designated is fulfilled. As such, the adoption of EITF No. 02-16 during fiscal
2003 did not have a material impact on our consolidated financial statements.

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 adopted the provisions of the statement, which has had no
material impact.

In January 2003, the FASB issued Interpretation 46, "Consolidation of Variable
Interest Entities" (FIN 46). FIN 46 interprets ARB No. 51, "Consolidated
Financial Statements," as amended by FASB Statement No. 94, "Consolidation of
All Majority-Owned Subsidiaries," which requires the preparation of consolidated
financial statements when one entity has a controlling financial interest in a
second entity. FIN 46 specifies disclosures that are required for financial
statements issued after January 31, 2003 but prior to the effective date of the
Interpretation for entities created before February 1, 2003 and interests in
those entities acquired before that date, as well as disclosures that will be
required for financial statements of primary beneficiaries and others with
variable interests in variable interest entities issued after the effective
date. The FASB has published a revision to Interpretation 46 to clarify some of
the provisions of FIN 46 and to exempt certain entities from its provisions. The
adoption of this interpretation did not have a material impact on our results of
operations or financial position, as we do not have variable interest entities.

In April 2003, the FASB issued Statement No. 149, "Amendment of Statement 133 on
Derivative Instruments and Hedging Activities." The Statement amends and
clarifies accounting for derivative instruments, including certain derivative
instruments embedded in other contracts, and for hedging activities under
Statement 133. Data I/O has adopted the provisions of the statement, which has
had no material impact.

In May 2003, the FASB issued Statement No. 150, "Accounting for Certain
Financial Instruments with Characteristics of both Liabilities and Equity." The
statement requires that certain financial instruments, which under previous
guidance were accounted for as equity, must now be accounted for as liabilities.
This statement is effective for all financial instruments entered into or
modified after May 31, 2003." The adoption of SFAS No 150 during fiscal 2003 did
not have a material impact on our consolidated financial statements.

Item 7A. Quantitative and Qualitative Disclosure About Market Risk

With respect to our foreign currency exchange rate risk, we currently use only
foreign currency hedge derivative instruments, which, at a given date, are not
material. However, Data I/O is exposed to interest rate risks. We generally
invest in high-grade commercial paper with original maturity dates of twelve
months or less and conservative money market funds to minimize our exposure to
interest rate risk on our marketable securities, which are classified as
available-for-sale as of December 31, 2003 and December 31, 2002. We believe
that the market risk arising from holdings of these financial instruments is not
material.

REPORT OF GRANT THORNTON LLP INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
- --------------------------------------------------------------------------------

To the Board of Directors and Stockholders
Data I/O Corporation

We have audited the accompanying consolidated balance sheets of Data I/O
Corporation as of December 31, 2003 and 2002, and the related consolidated
statements of operations, stockholders' equity and cash flows for each of the
three years in the period ended December 31, 2003. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Data I/O
Corporation as of December 31, 2003 and 2002, and the consolidated results of
their operations and their consolidated cash flows for each of the three years
in the period ended December 31, 2003, in conformity with accounting principles
generally accepted in the United States of America.

We have also audited Schedule II for the three years in the period ended
December 31, 2003. In our opinion, the schedule when considered in relation to
the basic consolidated financial statements taken as a whole, presents fairly,
in all material aspects, the information therein.

DATA I/O CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

Data I/O Corporation ("Data I/O") designs, manufactures, and sells programming
systems used by designers and manufacturers of electronic products. Our
programming system products are used to program integrated circuits ("ICs" or
"devices" or "semiconductors") with the specific unique data necessary for the
ICs contained in various products, and are an important tool for the electronics
industry experiencing growing use of programmable ICs. Customers for our
programming system products are located around the world, primarily in the
United States, Europe and the Far East. Our manufacturing operations are
currently located in the United States. An outside supplier located in Germany
currently manufactures our Sprint non-automated programming system.

As a result of our significant product development, customer support, and
selling and marketing efforts in a period of weak capital spending, Data I/O has
required substantial working capital to fund our operations. We believe that we
have sufficient working capital available under our operating plan to fund our
operations and capital requirements through at least December 31, 2004. Any
substantial inability to achieve the current business plan could have a material
adverse impact on our financial position, liquidity, or result of operations and
may require us to reduce expenditures and/or seek additional financing.

Principles of Consolidation

The consolidated financial statements include the accounts of Data I/O
Corporation and our wholly-owned subsidiaries. All significant intercompany
accounts and transactions have been eliminated in consolidation.

Reporting Period

In 2001, Data I/O converted to reporting on a calendar year-end basis. The first
quarter of 2001 covered the period December 29, 2000 to March 31, 2001.

Use of Estimates

The preparation of the financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements, and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

Stock-Based Compensation

Data I/O has stock-based employee compensation plans that are described more
fully in Note 12. Data I/O applies APB Opinion 25, Accounting for Stock Issued
to Employees, and related Interpretations in accounting for our plans. Stock
expense in 2003, 2002, and 2001 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 earnings (loss) per share
if Data I/O had applied the fair value recognition provisions of FASB Statement
123, Accounting for Stock-Based Compensation, using the assumptions described in
Note 12, to our stock-based employee plans.



Data I/O's pro forma information follows (in thousands, except per share data):



Year Ended December
-------------------------------------------------
2003 2002 2001
--------------- -------------- ----------------


Net income (loss) - as reported $1,241 ($3,106) ($6,010)

Deduct: Total stock-based employee compensation expense
determined under fair value based method for awards
granted, modified, or settled, net of related tax effects
(338) (392) (440)
--------------- -------------- ----------------
Net income (loss) - pro forma $903 ($3,498) ($6,450)
=============== ============== ================

Basic earnings (loss) per share - as reported $0.16 ($0.40) ($0.79)
Diluted earnings (loss) per share - as reported $0.15 ($0.40) ($0.79)
Basic earnings (loss) per share - pro forma $0.11 ($0.45) ($0.85)
Diluted earnings (loss) per share - pro forma $0.11 ($0.45) ($0.85)


Foreign Currency Translation

Assets and liabilities of foreign subsidiaries are translated at the exchange
rate on the balance sheet date. Revenues, costs and expenses of foreign
subsidiaries are translated at average rates of exchange prevailing during the
year. Translation adjustments resulting from this process are charged or
credited 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.

In an effort to minimize the effect of exchange rate fluctuations on the results
of our operations, Data I/O hedges portions of our foreign currency exposure
through the use of forward exchange contracts, none of which are speculative. At
December 31, 2003, we had a notional value of approximately $623,000 in five
foreign exchange contracts outstanding, the fair value of which was a liability
of $31,000. The contract terms are 43-90 days. The hedges are perfectly
effective, as currency, settlement date and amount of the underlying receivables
and of the forward contracts coincide, and as spot rates are the same for both
the hedge and the hedged item.

Cash and Cash Equivalents

Cash and cash equivalents are highly liquid investments with maturities of three
months or less at date of purchase.

Marketable Securities

Data I/O generally invests in debt securities with original maturities of twelve
months or less and money market funds, all of which are classified as
available-for-sale securities and recorded at fair value, as defined below. We
record unrealized holding gains and losses, net of any tax effect, as a
component of accumulated other comprehensive income (loss) within stockholders'
equity. We report interest earned in non-operating income as interest income.
Marketable securities are classified in the balance sheet as current and
noncurrent based on maturity dates and our expectation of sales and redemptions
in the following year.

Fair Value of Financial Instruments

The carrying value of cash, cash equivalents, marketable securities and forward
exchange contracts approximates fair value. The fair value of Data I/O's
marketable securities is based upon the quoted market price on the last business
day of the fiscal year plus accrued interest, if any.

Accounts Receivable

The majority of Data I/O's accounts receivable are due from companies in the
electronics manufacturing industries. Credit is extended based on an evaluation
of a customer's financial condition and, generally, collateral is not required.
Accounts receivable are typically due within 30 to 60 days and are stated at
amounts due from customers net of an allowance for doubtful accounts. Accounts
outstanding longer than the contractual payment terms are considered past due.
Data I/O determines our allowance by considering a number of factors, including
the length of time trade accounts receivable are past due, Data I/O's previous
loss history, the customer's current ability to pay our obligation to Data I/O,
and the condition of the general economy and the industry as a whole. Data I/O
writes off accounts receivable when they become uncollectible, and payments
subsequently received on such receivables are credited to the allowance for
doubtful accounts. Interest is allowed to accrue, according to our standard
sales terms, beginning on the day after the due date of the receivable. However,
interest income is subsequently recognized on these accounts only to the extent
cash is received, or when the future collection of interest and the receivable
balance is considered probable by management.

Inventories

Inventories are stated at the lower of cost or market with cost being the
currently adjusted standard cost, which approximates cost on a first-in,
first-out basis.

Property, Plant and Equipment

Property, plant and equipment, including leasehold improvements, are stated at
cost and depreciation is calculated over the estimated useful lives of the
related assets or lease terms on the straight-line basis. We depreciate
substantially all manufacturing and office equipment over periods of three to
seven years. We depreciate leasehold improvements over the remaining portion of
the lease, or over the expected life of the asset if less than the remaining
term of the lease.

Long-lived and other assets are evaluated on an annual basis for impairment. In
this connection, we reviewed the expected cash flows to be generated by the
Sprint product line to determine that they are adequate compared to the
remaining net book value of long-lived assets from the SMS acquisition.

Revenue Recognition

Sales of Data I/O's 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. Sales were recorded net of
associated sales return reserves, which were $300,000 and $450,000 at December
31, 2003 and 2002, respectively.

Data I/O previously recognized revenue from product sales at the time of
shipment, or at customer acceptance, if an acceptance clause was specified in
the sales terms. Effective December 31, 1999, we changed our method of
accounting for product sales requiring Company installation, when installation
is other than perfunctory, to recognize such revenues when installation is
complete, or at the later of customer acceptance or installation, if an
acceptance clause is specified in the sales terms. We believe the change in
accounting principle is preferable based on guidance provided in SEC Staff
Accounting Bulletin No. 101 (SAB 101), Revenue Recognition in Financial
Statements. This change in accounting principle did not impact taxes, as all
affected jurisdictions had net operating loss carryforwards.

Data I/O's software products are not normally sold separately from sales of
programming systems. However, on those occasions where we sell software
separately, we recognize revenue when a sales agreement exists, when delivery
has occurred, when the fee is fixed or determinable, and when collectibility is
probable.

Research and Development

Research and development costs are expensed as incurred.

Advertising Expense

Data I/O expenses advertising costs as incurred. Total advertising expenses
related to continuing operations were $248,000, $468,000, and $487,000 in 2003,
2002, and 2001, respectively.



Warranty Expense

Data I/O records a liability for an estimate of costs that it expects to incur
under our basic limited warranty when product revenue is recognized. Factors
affecting our warranty liability include the number of units sold and historical
and anticipated rates of claims and costs per claim. We periodically assess the
adequacy of our warranty liability based on changes in these factors. Data I/O
normally warrants our products against defects for periods ranging from ninety
days to one year. The FlashPAK, which we recently introduced, carries a
three-year warranty on some components. We provide currently for the estimated
cost that may be incurred under our product warranties. Data I/O records
revenues on extended warranties on a straight-line basis over the term of the
related warranty contracts. Service costs are expensed as incurred.

Earnings(Loss)Per Share

Basic earnings (loss) per share exclude any dilutive effects of stock options.
Basic earnings (loss) per share are computed using the weighted-average number
of common shares outstanding during the period. Diluted earnings (loss) per
share are computed using the weighted-average number of common shares and common
stock equivalent shares outstanding during the period. Common stock equivalent
shares are excluded from the computation if their effect is antidilutive.

Earnings per share as presented on the statement of operations exclude employee
stock options that were antidilutive of 1,141,412 and 1,115,508 in 2002, and
2001, respectively.

Diversification of Credit Risk

Financial instruments, which potentially subject Data I/O to concentrations of
credit risk, consist primarily of trade receivables. Our cash, cash equivalents
and marketable securities consist of high quality financial instruments. Data
I/O maintains cash balances in financial institutions, which at times may exceed
federally insured limits. We have not experienced any losses in such accounts
and believe we are not exposed to any significant credit risk on cash and cash
equivalents. Our trade receivables are geographically dispersed and include
customers in many different industries. We believe that any risk of loss is
significantly reduced due to the diversity of our end-customers and geographic
sales areas. We perform on-going credit evaluations of our customers' financial
condition and require collateral, such as letters of credit and bank guarantees,
whenever deemed necessary.

Derivatives

Data I/O accounts for our derivatives using 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 of our hedging instruments 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 fair value of the
open hedge contracts as of December 31, 2003 is a liability of $31,000 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. We are exposed to credit-related
losses in the event of nonperformance by counterparties to forward exchange
contracts. However, we have entered into these instruments with creditworthy
financial institutions and consider the risk of nonperformance remote.

New Accounting Pronouncements

During 2001, the Financial Accounting Standards Board (FASB) issued Statement of
Financial Accounting Standards (SFAS) No. 143 "Accounting for Asset Retirement
Obligations" and, during 2002, the FASB issued SFAS No.146, "Accounting for
Costs Associated with Exit and Disposal Activities". The adoption of SFAS Nos.
143 and 146 during fiscal 2003 did not have a material impact on our
consolidated financial statements.

In November 2002, the Emerging Issues Task Force (EITF) released Issue No.
02-16, "Accounting by a Customer (including a Reseller) for Certain
Consideration Received from a Vendor", applicable to Data I/O for arrangements
entered into beginning in fiscal 2003. Data I/O records vendor allowances and
discounts in the income statement when the purpose for which those monies were
designated is fulfilled. As such, the adoption of EITF No. 02-16 during fiscal
2003 did not have a material impact on our consolidated financial statements.

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 adopted the provisions of the statement, which has had no
material impact.

In January 2003, the FASB issued Interpretation 46, "Consolidation of Variable
Interest Entities" (FIN 46). FIN 46 interprets ARB No. 51, "Consolidated
Financial Statements," as amended by FASB Statement No. 94, "Consolidation of
All Majority-Owned Subsidiaries," which requires the preparation of consolidated
financial statements when one entity has a controlling financial interest in a
second entity. FIN 46 specifies disclosures that are required for financial
statements issued after January 31, 2003 but prior to the effective date of the
Interpretation for entities created before February 1, 2003 and interests in
those entities acquired before that date, as well as disclosures that will be
required for financial statements of primary beneficiaries and others with
variable interests in variable interest entities issued after the effective
date. The FASB has published a revision to Interpretation 46 to clarify some of
the provisions of FIN 46 and to exempt certain entities from its provisions. The
adoption of this interpretation did not have a material impact on our results of
operations or financial position, as we do not have variable interest entities.

In April 2003, the FASB issued Statement No. 149, "Amendment of Statement 133 on
Derivative Instruments and Hedging Activities." The Statement amends and
clarifies accounting for derivative instruments, including certain derivative
instruments embedded in other contracts, and for hedging activities under
Statement 133. Data I/O has adopted the provisions of the statement, which has
had no material impact.

In May 2003, the FASB issued Statement No. 150, "Accounting for Certain
Financial Instruments with Characteristics of both Liabilities and Equity." The
statement requires that certain financial instruments, which under previous
guidance were accounted for as equity, must now be accounted for as liabilities.
This statement is effective for all financial instruments entered into or
modified after May 31, 2003." The adoption of SFAS No 150 during fiscal 2003 did
not have a material impact on our consolidated financial statements.

NOTE 2 - PROVISION FOR BUSINESS RESTRUCTURING

During 2003, we completed the restructuring that began during 2001, which
included 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 over
the past few years. At the end of 2003 our breakeven point was approximately
$6.2 million in net sales with 127 employees worldwide. Our breakeven point
increased in 2003, primarily due to cost increases resulting from the impact of
the weaker dollar on foreign currency based costs and from personnel costs due
to salary increases, incentive compensation and selective hiring of individuals
with critical skills to help position us as the continuing technology leader in
our market.

During 2002, we recorded restructuring charges of $632,000 in connection with
our actions to reduce our quarterly breakeven point from approximately $7
million of net sales at the beginning of 2002 to approximately $5.7 million at
the end of 2002. We achieved most of these reductions by reducing our personnel
from 155 at the beginning of 2002 to 125 at the end of 2002.

During 2001, we recorded restructuring charges of $1,211,000 in connection with
a number of strategic restructuring actions to reduce our breakeven point. This
restructuring included the following: a reduction in our global workforce from
224 at the start of the year to 155 at the end of 2001; discontinuance or
reallocation of numerous projects and activities not essential to our long-term
goals; streamlining activities to decrease discretionary marketing, distribution
and promotional expenses; consolidation of numerous functions across the
organization to create a team, which was more productive and able to respond
faster to global customer needs; and closure of a facility in Germany and moving
our operations to other locations within Data I/O.

At December 31, 2003 all restructuring expenses associated with the activities
detailed above had been paid and the excess expense accrual of $39,000 was
reversed during 2003.


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

NOTE 3 - MARKETABLE SECURITIES

The estimated fair value of marketable securities consisted of the following (in
thousands):

Dec.31, Dec.31
2003 2002
------------- -------------

Corporate bonds $754 $734
Euro-dollar bonds - 342
Taxable auction securities 500 -
Tax advantaged auction securities 1,100 -
------------- -------------
$2,354 $1,076
============= =============

At December 31, 2003, cost approximated market value for Data I/O's portfolio of
marketable securities and there were no significant unrealized gains or losses.
The marketable securities are all classified as current assets due to their
maturity date or because of the available for sale holding intent, as in the
case of corporate bonds having a maturity date in the second quarter of 2005.
The cost of securities sold is determined by the specific identification method.

NOTE 4 - ACCOUNTS RECEIVABLE

Receivables consist of the following (in thousands):

Dec. 31, Dec.31,
2003 2002
-------------- ----------------

Trade receivables $5,249 $4,436
Other 7 79
-------------- -----------------
Total 5,256 4,515
Less allowance for doubtful receivables 202 187
-------------- -----------------
Net receivables $5,054 $4,328
=============== =================

Trade receivables relate to sales of parts, for which credit is extended based
on the customer's credit history. Other receivables represent amounts due for
subcontracting work performed for others.

Changes in Data I/O's allowance for doubtful accounts are as follows (in
thousands):

Dec.31, Dec. 31,
2003 2002
-------------- -----------------

Beginning balance $187 $372
Bad debt expense (reversal) 43 (162)
Accounts written-off (28) (37)
Recoveries - 14
---------------- -----------------
Ending balance $202 $187
================ =================


NOTE 5 - INVENTORIES

Net inventories consisted of the following components (in thousands):

Dec. 31, Dec. 31,
2003 2002
------------------ -----------------

Raw material $2,100 $2,308
Work-in-process 1,411 875
Finished goods 1,096 1,293
------------------ -------------------
$4,607 $4,476
================== ===================

Reserves for excess and obsolete inventory were $2,296,000 and $3,267,000 at
December 31, 2003 and December 31, 2002, respectively. The $971,000 decline in
the reserve related primarily to scrapping and disposal of the related inventory
and reversal of $96,000 in cost of goods sold. Freight expense for incoming raw
materials and freight out for product shipments is charged to cost of goods
sold.

Certain parts used in Data I/O's products are currently available from either a
single supplier or from a limited number of suppliers. If we cannot develop
alternative sources for these components, or if 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 Data I/O relies 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 underestimate 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.

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

NOTE 6 - SALE - LEASEBACK

In May 1997, Data I/O completed the sale of the land and building comprising our
Redmond, Washington, corporate headquarters. The sale includes a 10-year
leaseback of the building to Data I/O. The sale represented an overall pre-tax
gain to Data I/O of $5.6 million. Of this amount, we recognized $2.3 million in
1997, with the remainder being amortized over the life of the lease.



NOTE 7 - PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment consisted of the following (in thousands):

Dec. 31, Dec. 31,
2003 2002
-------------- --------------

Leasehold improvements $ 259 $ 239
Equipment 12,016 12,132

Less accumulated depreciation 11,124 10,863
-------------- --------------

Property, plant and equipment - net $1,151 $ 1,508
============== ==============

Total depreciation recorded for 2003, 2002, and 2001 was $667,000, $670,000, and
$940,000, respectively.

NOTE 8 - OTHER ASSETS

Other assets consisted of the following components (in thousands):

Dec. 31, Dec. 31
2003 2002
-------------- --------------

Long-term lease deposits $ 11 $ 66
Investment in product lines: SMS 3,272 3,272
-------------- --------------
3,283 3,338
Less accumulated amortization 3,272 3,251
-------------- --------------
Other assets - net $ 11 $ 87
============== ==============

Total amortization recorded for 2003, 2002, and 2001 was $59,000, $81,000, and
$969,000, respectively.

Investment in Product Lines: SMS

In November 1998, Data I/O acquired SMS Holding GmbH. In related transactions,
we acquired a license to the technology, manufacturing and worldwide
distribution rights to Unmanned Solutions' AH 400 robotic handler, which is used
in the fine pitch automated programming system, now the PS product family. Of
the total acquisition costs of these transactions, approximately $3.3 million of
developed technology and other various intangible assets are reported as Other
Assets in the accompanying balance sheets and are being amortized ratably over
the economic life of the specific assets acquired (three to five years). The net
book value of the assets capitalized in Other Assets related to this acquisition
is $0 and $59,000 at December 31, 2003 and 2002, respectively.

NOTE 9 - WARRANTY

The changes in Data I/O's product warranty liability are as follows (in
thousands):

December 31, December 31,
2003 2002
----------------- ----------------

Liability, beginning of year $519 $578
Net expense, accrual revisions
and warranty claims 44 (59)
------------------ ----------------
Liability, end of year $563 $519
================== ================



NOTE 10 - AGGREGATE CONTRACTUAL OBLIGATIONS AND COMMITTMENTS

Data I/O has purchase obligations for inventory and production costs as well as
other obligations such as capital expenditures, service contracts, marketing,
and development agreements. Arrangements are considered purchase obligations if
a contract specifies all significant terms, including fixed or minimum
quantities to be purchased, a pricing structure and approximate timing of the
transaction. Most arrangements are cancelable without a significant penalty, and
with short notice, typically less than 90 days. Any amounts reflected on the
balance sheet as accounts payable and accrued liabilities are excluded from the
below table. Data I/O has no long-term debt. Data I/O has commitments under
non-cancelable operating leases and other agreements, primarily for factory and
office space, with initial or remaining terms of one year or more as follows:

For the years ending December 31, (in thousands):

2008 and thereafter - -
---------------- ----------------
Total $1,440 $4,111
================ ================

Lease and rental expense was $1,476,000, $1,387,000 and $1,342,000 in 2003, 2002
and 2001, respectively. Data I/O has renewal options on substantially all of our
major leases. The initial lease on the Redmond facility expires on December 31,
2006. So long as we are not in material default of the terms of the lease and
there has not been a material adverse change in the financial condition of Data
I/O, we have the option to extend the lease for an additional five years on the
same terms as the balance of the lease, except the rent shall be at the
then-prevailing fair market rental rate. We will also have the right for a
second five-year extension by giving written notice at least six months prior to
the end of the first extension.

As part of our restructuring plan implementation, Data I/O vacated one floor of
our leased Redmond facility (approximately 25,000 square feet) and sublet the
majority of this space for a period of 28 months beginning January 1, 2000. This
sublease ended in June 2002. We have not been successful in subleasing this
space since June 2002 and believe the market for this space is currently quite
limited.

NOTE 11 - STOCK AND RETIREMENT PLANS

Stock Option Plans

At December 31, 2003, there were 1,595,215 shares of Common Stock reserved for
issuance of which 268,410 shares are available for future grant under Data I/O's
employee stock option plans. Pursuant to these plans, options are granted to our
officers and key employees with exercise prices equal to the fair market value
of the Common Stock at the date of grant and generally vest over four years.
Certain options granted during 1998 and 1999 vest over two years. Options
granted under the plans generally have a maximum term of six years from the date
of grant, except for certain options granted in January 1999, which have a
maximum term of ten years. On May 15, 2002, Data I/O's shareholders approved an
amendment to the Data I/O Corporation 2000 Stock Incentive Compensation Plan
increasing the number of shares reserved for issuance under the 2000 Plan by an
additional 200,000 shares of Common Stock.

Employee Stock Purchase Plan

Under the Employee Stock Purchase Plan, eligible employees may purchase shares
of Data I/O's Common Stock at six-month intervals at 85% of the lower of the
fair market value on the first or the last day of each six-month period.
Employees may purchase shares having a value not exceeding 10% of their gross
compensation during an offering period. During 2003, 2002 and 2001, a total of
194,477, 148,876, and 119,212 shares, respectively, were purchased under the
plan at average prices of $0.61, $0.87, and $1.66 per share, respectively. At
December 31, 2003, a total of 274,638 shares were reserved for future issuance.



Stock Appreciation Rights Plan

Data I/O has a Stock Appreciation Rights Plan ("SAR") under which each director,
executive officer or holder of 10% or more of Data I/O's Common Stock has a SAR
with respect to each exercisable stock option. The SAR entitles the SAR holder
to receive cash from Data I/O for the difference between the market value of the
stock and the exercise price of the option in lieu of exercising the related
option. SARs are only exercisable following a tender offer or exchange offer for
Data I/O's stock, or following approval by shareholders of Data I/O of any
merger, consolidation, reorganization or other transaction providing for the
conversion or exchange of more than 50% of the common shares outstanding. As no
event has occurred, which would make the SARs exercisable, and no such event is
deemed probable, no compensation expense has been recorded under this plan.

Director Fee Plan

Data I/O has a Director Fee Plan, not currently in use, which had provided for
payment to directors who are not employees of Data I/O Corporation by delivery
of shares of Data I/O's Common Stock. No shares were issued from the plan for
2003, 2002 or 2001 board service and 151,332 shares remain available in the
plan.

Retirement Savings Plan

Data I/O has a savings plan that qualifies as a cash or deferred salary
arrangement under Section 401(k) of the Internal Revenue Code. Under the plan,
participating U.S. employees may defer their pre-tax salary, subject to IRS
limitations. In fiscal years 2003, 2002 and 2001, Data I/O contributed one
dollar for each dollar contributed by a participant, with a maximum contribution
of 4% of a participant's earnings. Data I/O's matching contribution expense for
the savings plan was approximately $161,000, $173,000 and $271,000 in 2003, 2002
and 2001, respectively.

Share Repurchase Program

Under a previously announced share repurchase program, Data I/O is authorized to
repurchase up to 1,123,800 shares of our outstanding Common Stock. These
purchases may be executed through open market purchases at prevailing market
prices, through block purchases or in privately negotiated transactions, and may
commence or be discontinued at any time. In years, prior to 2003, we have
repurchased 1,016,200 shares under this repurchase program at a total cost of
approximately $7.1 million. We have not repurchased shares under this plan since
the second quarter of 1997, although we still have the authority to do so.

NOTE 12- STOCK-BASED COMPENSATION

Pro forma information regarding net income and earnings per share is required by
SFAS 123, and has been determined as if Data I/O had accounted for our employee
stock options, employee stock purchase plan options and directors' fee shares
under the fair value method of that Statement. The fair value for these options
was estimated at the date of grant using a Black-Scholes option-pricing model
with the following weighted-average assumptions:

For purposes of pro forma disclosures, the estimated fair value of the options
granted, which is estimated to be $1.01, $0.92 and $1.36 per share for 2003,
2002 and 2001, respectively, is amortized to expense over the options' vesting
period.

--------------- ----------------
Total deferred income tax assets $ - $ -
=============== ================


The valuation allowance for deferred tax assets decreased $402,000 during the
year ended December 31, 2003, due primarily to the 2003 net income that allowed
the utilization of tax deferred assets reducing the valuation allowance. The
valuation allowance for deferred tax assets increased $1,173,000 during the year
ended December 31, 2002, due primarily to taxable losses and to credit
carryforwards generated in 2002. The net deferred tax assets have a full
valuation allowance provided due to uncertainty regarding Data I/O's ability to
utilize such assets in future years. Credit carryforwards consist primarily of
research and experimental and alternative minimum tax credits. Net operating
loss carryforwards expire in 2019 to 2023. Utilization of net operating loss and
credit carryforwards is subject to certain limitations under Section 382 of the
Internal Revenue Code of 1986, as amended.



NOTE 15 - SEGMENT AND GEOGRAPHIC INFORMATION

In 2003, one customer accounted for 18% of Data I/O's consolidated revenues and
no other customer accounted for more than 10%. No customer accounted for more
than 10% of consolidated revenues in 2002 and 2001. Major operations outside the
U.S. include sales and service support subsidiaries in Germany, Canada and
China.

We present geographic information of the continuing operations for the three
years ended December 31, 2003 in the table that follows. Net sales, as shown in
the table below, are based upon the geographic area into which the products were
sold and delivered. Export sales are subject to U.S. Department of Commerce
regulations, and to the market conditions in the countries in which the products
are sold. For purposes of the table below, the profit on the transfers between
geographic areas has been shown in operating income in the geographic area where
the final sale to non-affiliated customers took place. Certain general corporate
expenses are charged to the U.S. segment. Identifiable assets are those assets
that can be directly associated with a particular geographic area. All Company
financial instruments, consisting of cash and marketable securities, are
included in U.S. operations.

NOTE 16 - QUARTERLY FINANCIAL INFORMATION (unaudited)

The following table sets forth unaudited selected quarterly financial data for
Data I/O for 2003 and 2002. Although our business is not seasonal, growth rates
of sales and earnings have varied from quarter to quarter as a result of factors
such as stocking orders from international distributors, the timing of new
product introductions, business acquisitions and dispositions, business
restructuring, and short-term industry and general U.S. and international
economic conditions. Information as to any one or more quarters is, therefore,
not necessarily indicative of trends in our business or profitability.

(1) The sum of quarterly per share amounts may not equal per share amounts
reported for year-to-date periods. This is due to changes in the number of
weighted-average shares outstanding and the effects of rounding for each
period.

NOTE 17 - LONG-TERM DEBT

As of December 31, 2003 and December 31, 2002, Data I/O had no long-term debt
outstanding. Data I/O established a foreign line of credit for 50,000 Euros in
February 2002 that was renewed in 2003, but we did not renew it in January 2004.

may be required by law, and the registered agent shall have a business office
identical with such registered office.

(2) Other Offices: The corporation may have other offices within or outside the
State of Washington at such place or places as the Board of Directors may from
time to time determine.

ARTICLE II

registered office of the corporation, or at such other place as shall be
determined from time to time by the Board of Directors, and the place at which
any such meeting shall be held shall be stated in the notice of the meeting.

(2) Annual Meeting Time: The annual meeting of the shareholders for the election
of directors and for the transaction of such other business as may properly come
before the meeting, shall be held each year during the month of May on such date
and at such time as may be determined each year by the Board of Directors.

(3) Special Meetings: Special meetings of the shareholders for any purpose may
be called at any time by the President, Board of Directors, or the holders of
not less than one-tenth of all shares entitled to vote at the meeting in
accordance with RCW 23B.07.020.

(4) Notice:

(a) Notice of the time and place of the annual meeting of shareholders shall be
given by delivering personally or by mailing a written or printed notice of the
same, at least ten days, and not more than sixty days, prior to the meeting to
each shareholder of record entitled to vote at such meeting.

(b) At least ten days and not more than sixty days prior to the meeting, written
or printed notice of each special meeting of shareholders, stating the place,
day and hour of such meeting, and the purpose or purposes for which the meeting
is called, shall be delivered personally, or mailed to each shareholder of
record entitled to vote at such meeting.

(c) Notice of a shareholders' meeting at which the shareholders will be called
to act on an amendment to the articles of incorporation, a plan of merger or
share exchange, a proposed sale of assets other than in the regular course of
business or the dissolution of the Corporation shall be given not fewer than
twenty days and not more than sixty days before the meeting date.

(5) Voting Record: At least ten days and not more than seventy days before each
meeting of shareholders, a complete record of the shareholders entitled to vote
at such meeting, or any adjournment thereof, shall be made, arranged in
alphabetical order, with the address of and number of shares held by each, which
record shall be kept on file at the registered office of the corporation for a
period of ten days prior to such meeting. The record shall be kept on file at
the registered office of the Corporation for a period beginning ten days prior
to such meeting and shall be kept open at the time and place of such meeting for
the inspection of any shareholder, or any shareholder's agent or attorney.

(6) Quorum: Except as otherwise required by law:

(a) A quorum at any annual or special meeting of shareholders shall consist of
shareholders representing, either in person or by proxy, a majority of the votes
entitled to be cast on the matter by each voting group.

(b) The votes of a majority in interest of those present at any properly called
meeting or adjourned meeting of shareholders at which a quorum as in this
paragraph defined is present shall be sufficient to transact business.

(7) Voting of Shares:

(a) Except as otherwise provided in these Bylaws or to the extent that voting
rights of the shares of any class or classes are limited or denied by the
Articles of Incorporation, each shareholder, on each matter submitted to a vote
at a meeting of shareholders, shall have one vote for each share of stock
registered in his name in the books of the corporation.

(b) If a quorum exists, action on a matter, other than the election of
directors, is approved by a voting group if the votes cast within the voting
group favoring the action exceed the votes cast within the voting group opposing
the action, unless the question is one which by express provision of law, of the
Articles of Incorporation or of these Bylaws a greater number of affirmative
votes is required.

(c) Unless otherwise provided in the Articles of Incorporation, in any election
of directors the candidates elected are those receiving the largest numbers of
votes cast by the shares entitled to vote in the election, up to the number of
directors to be elected by such shares.

(8) Closing of Transfer Books and Fixing Record Date: For the purpose of
determining shareholders notice of or to vote at any meeting of shareholders, or
any adjournment thereof, or entitled to receive payment of any dividend, the
Board of Directors may provide that the stock transfer books shall be closed for
a stated period not to exceed seventy days nor be less than ten days preceding
such meeting. In lieu of closing the stock transfer books, the Board of
Directors may fix in advance a record date for any such determination of
shareholders, such date to be not more than seventy days and, in case of a
meeting of shareholders, not less than ten days prior to the date on which the
particular action requiring such determination of shareholders is to be taken.

(9) Proxies: A shareholder may vote either in person or by proxy executed in
writing by the shareholder or his duly authorized attorney-in-fact or agent. An
appointment of a proxy is effective when received by the person authorized to
tabulate votes for the Corporation. No proxy shall be valid after eleven months
from the date of its execution, unless otherwise provided in the proxy.

(10) Action by Shareholders without a Meeting: Any action required or which may
be taken at a meeting of shareholders of the corporation may be taken without a
meeting if a consent in writing, setting forth the action so taken, shall be
signed by all of the shareholders entitled to vote with respect to the subject
matter thereof, and delivered to the Corporation for inclusion in the minutes or
filing with the Corporation's records. Such consent shall have the same force
and effect as a unanimous vote of shareholders. Action taken in accordance with
this section shall be effective when all written consents are in the possession
of the Corporation unless the consent specifies a later effective date.

(11) Waiver of Notice: A waiver of any notice required to be given any
shareholder, signed by the person or persons entitled to such notice, whether
before or after the time stated therein for the meeting shall be equivalent to
the giving of such notice provided that such waiver has been delivered to the
Corporation for inclusion in the minutes or filing with the Corporation's
records. A shareholder's attendance at a meeting waives any notice required,
unless the shareholder at the beginning of the meeting objects to holding the
meeting or transacting business at the meeting.

(12) Action of Shareholders by Communications Equipment: Shareholders may
participate in a meeting of shareholders by means of a conference telephone or
similar communications equipment by means of which all persons participating in
the meeting can hear each other at the same time, and participation by such
means shall constitute presence in person at a meeting.

(13) Notice of Shareholder Nominees: Nominations of persons for election to the
Board of Directors shall be made only at a meeting of shareholders and only (i)
by the Board of Directors or a committee appointed by the Board of Directors or
(ii) by any shareholder entitled to vote in the election of directors at the
meeting who complies with the notice procedures set forth in this Section 13.
Such nominations, other than those made by or at the direction of the Board of
Directors, shall be made pursuant to timely notice in writing to the Secretary
of the corporation. To be timely, a shareholder's notice shall be delivered to
or mailed and received at the principal executive offices of the corporation (i)
with respect to an election to be held at an annual meeting of shareholders,
ninety days prior to the date one year from the date of the immediately
preceding annual meeting of shareholders, and (ii) with respect to an election
to be held at a special meeting of shareholders for the election of directors,
the close of business on the tenth day following the date on which notice of
such meeting is first given to shareholders. For purposes of this Section 14,
any adjournment(s) or postponement(s) of the original meeting whereby the
meeting will reconvene within thirty days from the original date shall be deemed
for purposes of notice to be a continuation of the original meeting, and no
nominations by a shareholder of persons to be elected directors of the
corporation may be made at any such reconvened meeting unless pursuant to a
notice which was timely for the meeting on the date originally scheduled. Each
such notice shall set forth: (a) the name and address of the shareholder who
intends to make the nomination and of the person or persons to be nominated; (b)
a representation that the shareholder is a holder of record of stock of the
corporation entitled to vote at such meeting and intends to appear in person or
by proxy at the meeting to nominate the person or persons specified in the
notice; (c) a description of all arrangements or understandings between the
shareholder and each nominee and any other person or persons (naming such person
or persons) pursuant to which the nomination or nominations are to be made by
the shareholder; (d) such other information regarding each nominee proposed by
such shareholder as would be required to be disclosed in solicitations of
proxies for election of directors, or is otherwise required, in each case
pursuant to the Securities Exchange Act of 1934, as amended; and (e) the consent
of each nominee to serve as a director of the corporation if so elected.

Notwithstanding the foregoing, nothing in this Section 13 shall be interpreted
or construed to require the inclusion of information about any such nominee in
any proxy statement distributed by, at the direction of, or on behalf of the
Board of Directors. The Chairman of the meeting shall, if the facts warrant,
determine and declare to the meeting that a nomination was not made in
accordance with the foregoing procedures, and if he should so determine, he
shall so declare to the meeting and the defective nomination shall be
disregarded.

(14) Shareholder Proposals at Annual Meeting: Business may be properly brought
before an annual meeting by a shareholder only upon the shareholder's timely
notice thereof in writing to the Secretary of the corporation. To be timely, a
shareholder's notice must be delivered to or mailed and received at the
principal executive offices of the corporation not later than ninety days prior
to the date one year from the date of the immediately preceding annual meeting
of shareholders. For purposes of this Section 14, any adjournment(s) or
postponement(s) of the original meeting whereby the meeting will reconvene
within thirty days from the original date shall be deemed for purposes of notice
to be a continuation of the original meeting, and no business may be brought
before any reconvened meeting unless pursuant to a notice which was timely for
the meeting on the date as originally scheduled. Each such notice shall set
forth: (a) the name and address of the shareholder who intends to make the
proposal; (b) a representation that the shareholder is a holder of record of
stock of the corporation entitled to vote at such meeting and intends to appear
in person or by proxy at the meeting to vote for the proposal; (c) any material
interest of such shareholder in such proposal; and (d) such other information
regarding such proposal as would be required to be disclosed in solicitations of
proxies pursuant to the Securities Exchange Act of 1934, as amended.

Notwithstanding the foregoing, nothing in this Section 14 shall be interpreted
or construed to require the inclusion of information about any such proposal in
any proxy statement distributed by, at the discretion of, or on behalf of the
Board of Directors. The Chairman of the meeting shall, if the facts warrant,
determine and declare to the meeting that a proposal was not made in accordance
with the foregoing procedures, and if he should so determine, he shall so
declare to the meeting, and any such business not properly brought before the
meeting shall be disregarded.

ARTICLE III Stock

(1) Issuance of Shares: No shares of the Corporation shall be issued unless
authorized by the Board of Directors. Such authorization shall include the
number of shares to be issued, the consideration to be received and a statement
regarding the adequacy of the consideration.

(2) Certificates: Certificates of stock shall be issued in numerical order, and
each shareholder shall be entitled to a certificate signed by the President, or
a Vice President, and the Secretary or an Assistant Secretary, and may be sealed
with the seal of the corporation or a facsimile thereof. The signatures of such
officers may be facsimiles if the certificate is manually signed on behalf of a
transfer agent, or registered by a registrar, other than the corporation itself
or an employee of the corporation. If an officer who has signed or whose
facsimile signature has been placed upon such certificate ceases to be an
officer before the certificate is issued, it may be issued by the corporation
with the same effect as if the person were an officer on the date of issue.

At a minimum each certificate of stock shall state:

(a) the name of the Corporation;

(b) that the Corporation is organized under the laws of the State of Washington;

(c) the name of the person to whom the certificate is issued;

(d) the number and class of shares and the designation of the series, if any,
the certificate represents; and

(e) if the Corporation is authorized to issue different classes of shares or
different series within a class, the designations, relative rights, preferences
and limitations applicable to each class and the variations in rights,
preferences and limitations determined for each series, and the authority of the
Board of Directors to determine variations for future series, must be summarized
either on the front or back of the certificate. Alternatively, the certificate
may state conspicuously on its front or back that the Corporation will furnish
the shareholder this information without charge on request in writing.

(3) Transfers:

(a) Transfers of stock shall be made only upon the stock transfer books of the
corporation, kept at the registered office of the corporation or at its
principal place of business, or at the office of its transfer agent or
registrar, and before a new certificate is issued the old certificate shall be
surrendered for cancellation. The Board of Directors may, by resolution, open a
share register in any state of the United States, and may employ an agent or
agents to keep such register, and to record transfers of shares therein.

(b) Shares of certificated stock shall be transferred by delivery of the
certificates therefor, accompanied either by an assignment in writing on the
back of the certificate or an assignment separate from certificate, or by a
written power of attorney to sell, assign and transfer the same, signed by the
holder of said certificate. No shares of certificated stock shall be transferred
on the records of the Corporation until the outstanding certificates therefor
have been surrendered to the Corporation or to its transfer agent or registrar.

(4) Registered Owner: Registered shareholders shall be treated by the
corporation as the holders in fact of the stock standing in their respective
names and the corporation shall not be bound to recognize any equitable or other
claim to or interest in any share on the part of any other person, whether or
not it shall have express or other notice thereof, except as expressly provided
below or by the laws of the State of Washington. The Board of Directors may
adopt by resolution a procedure whereby a shareholder of the corporation may
certify in writing to the corporation that all or a portion of the shares
registered in the name of such shareholder are held for the account of a
specified person or persons. The resolution shall set forth:

(a) The classification of shareholder who may certify;

(b) The purpose or purposes for which the certification may be made;

(c) The form of certification and information to be contained therein;

(d) If the certification is with respect to a record date or closing of the
stock transfer books, the date within which the certification must be received
by the corporation; and

(e) Such other provisions with respect to the procedure as are deemed necessary
or desirable.

Upon receipt by the corporation of a certification complying with the procedure,
the persons specified in the certification shall be deemed, for the purpose or
purposes set forth in the certification, to be the holders of record of the
number of shares specified in place of the shareholder making the certification.

(5) Mutilated, Lost or Destroyed Certificates: In case of any mutilation, loss
or destruction of any certificate of stock, another may be issued in its place
on proof of such mutilation, loss or destruction. The Board of Directors may
impose conditions on such issuance and may require the giving of a satisfactory
bond or indemnity to the corporation in such sum as they might determine or
establish such other procedures as they deem necessary.

(6) Fractional Shares or Scrip: The corporation, by resolution of the Board of
Directors, may either: (a) issue fractions of a share which shall entitle the
holder to exercise voting rights, to receive dividends thereon, and to
participate in any of the assets of the corporation in the event of liquidation;
(b) arrange for the disposition of fractional interests by those entitled
thereto; (c) pay in cash the fair value of fractions of a share as of the time
when those entitled to receive such shares are determined; or (d) issue scrip in
registered or bearer form which shall entitle the holder to receive a
certificate for a full share upon the surrender of such scrip aggregating a full
share.

(7) Shares of Another Corporation: Shares owned by the corporation in another
corporation, domestic or foreign, may be voted by such officer, agent or proxy
as the Board of Directors may determine or, in the absence of such
determination, by the President of the corporation.

ARTICLE IV

Board of Directors

(1) Number and Powers: The management of all the affairs, property and interest
of the corporation shall be vested in a Board of Directors consisting of seven
(7) persons, who shall be elected for a term of one year, and shall hold office
until their successors are elected and qualified. Directors need not be
shareholders or residents of the State of Washington. In addition to the powers
and authorities by these Bylaws and the Articles of Incorporation expressly
conferred upon it, the Board of Directors may exercise all such powers of the
corporation and do all such lawful acts and things as are not prohibited by
statute or by the Articles of Incorporation or by these Bylaws or as directed or
required to be exercised or done by the shareholders.

(2) Change of Number: The number of directors may at any time be increased or
decreased by amendment of these Bylaws, but no decrease shall have the effect of
shortening the term of any incumbent directors, except as provided in Sections 5
and 6 of this Article IV.

(3) Vacancies: All vacancies in the Board of Directors, whether caused by
resignation, death or otherwise, may be filled by the affirmative vote of a
majority of the remaining directors though less than a quorum of the Board of
Directors. A director elected to fill any vacancy shall hold office for the
unexpired term of his or her predecessor and until his or her successor is
elected and qualified. Any directorship to be filled by reason of an increase in
the number of directors may be filled by the Board of Directors for a term of
office continuing only until the next election of directors by the shareholders
and until his or her successor is elected and qualified.

(4) Resignation: A director may resign at any time by delivering written notice
to the Board of Directors, the President or the Secretary. A resignation is
effective when the notice is delivered unless the notice specifies a later
effective date.

(5) Removal of Directors: At a special meeting of shareholders called expressly
for that purpose, the entire Board of Directors, or any member thereof, may be
removed by a vote of the holders of a majority of shares then entitled to vote
at an election of such directors. A director or directors may be removed only if
the number of votes cast to remove the director exceeds the number of votes cast
not to remove the director. The notice of such special meeting must state that
the purpose, or one of the purposes, of the meeting is removal of the director
or directors, as the case may be.

(6) Regular Meetings: Regular meetings of the Board of Directors or any
committee may be held without notice at the registered office of the corporation
or at such other place or places, either within or without the State of
Washington, as the Board of Directors or such committee, as the case may be, may
from time to time designate. The annual meeting of the Board of Directors shall
be held without notice immediately after the adjournment of the annual meeting
of shareholders.

(7) Special Meetings:

(a) Special meetings of the Board of Directors may be called at any time by the
President or by any two directors, to be held at the registered office of the
corporation or at such other place or places as the Board of Directors or the
person or persons calling such meeting may from time to time designate. Notice
of all special meetings of the Board of Directors shall be given to each
director by three day's service of the same by telegram, by letter, or
personally. Such notice need not specify the business to be transacted at, nor
the purpose of, the meeting.

(b) Special meetings of any committee may be called at any time by such person
or persons and with such notice as shall be specified for such committee by the
Board of Directors, or in the absence of such specification, in the manner and
with the notice required for special meetings of the Board of Directors.

(8) Quorum: A majority of the whole Board of Directors shall be necessary at all
meetings to constitute a quorum for the transaction of business. If a quorum is
present when a vote is taken, the affirmative vote of a majority of directors
present is the act of the Board of Directors.

(9) Waiver of Notice: Attendance of a director at a meeting shall constitute a
waiver of notice of such meeting, except where a director attends for the
express purpose of objecting to the transaction of any business because the
meeting is not lawfully called or convened and does not thereafter vote for or
assent to action taken at the meeting. A waiver of notice signed by the director
or directors and delivered to the Corporation for inclusion in the minutes or
filing with the corporate records, whether before or after the time stated for
the meeting, shall be equivalent to the giving of notice.

(10) Registering Dissent: A director who is present at a meeting of the Board of
Directors at which action on a corporate matter is taken shall be presumed to
have assented to such action unless his dissent shall be entered in the minutes
of the meeting, or unless he shall file his written dissent to such action with
the person acting as the secretary of the meeting, before the adjournment
thereof, or shall forward such dissent by registered mail to the Secretary of
the corporation within a reasonable time after the adjournment of the meeting.
Such right to dissent shall not apply to a director who voted in favor of such
action.

(11) Executive and Other Committees: The Board of Directors, by resolution
adopted by a majority of the full Board of Directors, may designate from among
its members an Executive Committee and one or more other standing or special
committees. The Executive Committee shall have and may exercise all the
authority of the Board of Directors, and other standing or special committees
may be invested with such powers, subject to such conditions, as the Board of
Directors shall see fit; provided that, notwithstanding the above, no committee
of the Board of Directors shall have the authority to: (1) Declare dividends or
distributions, except at a rate or in periodic amount determined by the Board of
Directors; (2) approve or recommend to shareholders actions or proposals
required by law to be approved by shareholders; (3) fill vacancies on the Board
of Directors or any committee thereof; (4) adopt, amend, or repeal the Bylaws;
(5) authorize or approve the reacquisition of shares unless pursuant to general
formula or method specified by the Board of Directors; (6) fix compensation of
any director for serving on the Board of Directors or on any committee thereof;
(7) approve a plan of merger, consolidation, or exchange of shares not requiring
shareholder approval; (8) reduce earned or capital surplus; or (9) appoint other
committees of the Board of Directors or the members thereof. All committees so
appointed shall keep regular minutes of their meetings and shall cause them to
be recorded in books kept for that purpose in the office of the corporation. The
designation of any such committee and the delegation of authority thereto shall
not relieve the Board of Directors, or any member thereof, of any responsibility
imposed by law.

(12) Remuneration: No stated salary shall be paid directors, as such, for their
service, but by resolution of the Board of Directors, a fixed sum and expenses
of attendance, if any, may be allowed for attendance at each regular or special
meeting of such Board; provided, that nothing herein contained shall be
construed to preclude any director from serving the corporation in any other
capacity and receiving compensation therefor. Members of standing or special
committees may be allowed like compensation for attending committee meetings.

(13) Loans: No loans shall be made by the corporation to the directors, unless
first approved by the holders of two-thirds of the voting shares. No loans shall
be made by the corporation secured by its own shares.

(14) Action by Directors Without a Meeting: Any action required or which may be
taken at a meeting of the directors, or of a committee thereof, may be taken
without a meeting if a consent in writing, setting forth the action so taken or
to be taken, shall be signed by all of the directors, or all of the members of
the committee, as the case may be, either before or after the action taken, and
delivered to the Corporation for inclusion in the minutes or filing with the
Corporation's records. Such consent shall have the same effect as a unanimous
vote.

(15) Action of Directors by Communications Equipment: Any action required or
which may be taken at a meeting of directors, or of a committee thereof, may be
taken by means of a conference telephone or similar communications equipment by
means of which all persons participating in the meeting can hear each other at
the same time.

the order designated by the Board of Directors, shall perform all of the duties
of the Secretary during the absence or disability of the Secretary, and at other
times may perform such duties as are directed by the President or the Board of
Directors.

(6) The Treasurer: The Treasurer shall have the custody of all moneys and
securities of the corporation and shall keep regular books of account. He shall
disburse the funds of the corporation in payment of the just demands against the
corporation or as may be ordered by the Board of Directors, taking proper
vouchers for such disbursements, and shall render to the Board of Directors from
time to time as may be required of him an account of all his transactions as
Treasurer and of the financial condition of the corporation. He shall perform
such other duties incident to his office or that are properly required of him by
the Board of Directors. The Assistant Treasurer, or Assistant Treasurers in the
order designated by the Board of Directors, shall perform all of the duties of
the Treasurer in the absence or disability of the Treasurer, and at other times
may perform such other duties as are directed by the President or the Board of
Directors.

(7) Delegation: In the case of absence or inability to act of any officer of the
corporation and of any person herein authorized to act in his place, the Board
of Directors may from time to time delegate the powers or duties of such officer
to any other officer or any director or other person whom it may in its sole
discretion select.

(8) Vacancies: Vacancies in any office arising from any cause may be filled by
the Board of Directors at any regular or special meeting of the Board.

(9) Other Officers: Directors may appoint such other officers and agents as it
shall deem necessary or expedient, who shall hold their offices for such terms
and shall exercise such powers and perform such duties as shall be determined
from time to time by the Board of Directors.

(10) Resignation: An officer may resign at any time by delivering notice to the
Corporation. Such notice shall be effective when delivered unless the notice
specifies a later effective date. Any such resignation shall not affect the
Corporation's contract rights, if any, with the officer.

(11) Loans: No loans shall be made by the corporation to any officer, unless
first approved by the holders of two-thirds of the voting shares.

(12) Term - Removal: The officers of the corporation shall hold office until
their successors are chosen and qualify. Any officer or agent elected or
appointed by the Board of Directors may be removed at any time, with or without
cause, by the affirmative vote of a majority of the whole Board of Directors,
but such removal shall be without prejudice to the contract rights, if any, of
the person so removed.

(13) Salaries and Contract Rights: The salaries, if any, of the officers shall
be fixed from time to time by the Board of Directors. The appointment of an
officer shall not of itself create contract rights.

(14) Bonds: The Board of Directors may, by resolution, require any and all of
the officers to give bonds to the corporation, with sufficient surety or
sureties, conditioned for the faithful performance of the duties of their
respective offices, and to comply with such other conditions as may from time to
time be required by the Board of Directors.

ARTICLE VI

(1) Distributions: The Board of Directors may authorize and the corporation may
make distributions to its shareholders; provided that no distribution may be
made if, after giving it effect, either:

(a) The Corporation would not be able to pay its debts as they become due in the
usual course of business; or

(b) The Corporation's total assets would be less than the sum of its total
liabilities plus the amount which would be needed, if the Corporation were to be
dissolved at the time of the distribution, to satisfy the preferential rights
upon dissolution of shareholders whose preferential rights are superior to those
receiving the distribution.

The Board of Directors may authorize distributions to holders of record at the
close of business on any business day prior to the date on which the
distribution is made. If the Board of Directors does not fix a record date for
determining shareholders entitled to a distribution, the record date shall be
the date on which the Board of Directors authorizes the distribution.

(2) Measure of Effect of a Distribution: For purposes of determining whether a
distribution may be authorized by the Board of Directors and paid by the
Corporation under Article VI, Section 1 of these Bylaws, the effect of the
distribution is measured:

(a) In the case of a distribution of indebtedness, the terms of which provide
that payment of principal and interest are made only if and to the extent that
payment of a distribution to shareholders could then be made under this section,
each payment of principal or interest is treated as a distribution, the effect
of which is measured on the date the payment is actually made; or

(b) In the case of any other distribution:

(i) if the distribution is by purchase, redemption, or other acquisition of the
Corporation's shares, the effect of the distribution is measured as of the
earlier of the date any money or other property is transferred or debt incurred
by the Corporation, or the date the shareholder ceases to be a shareholder with
respect to the acquired shares;

(ii) if the distribution is of an indebtedness other than described in
subsection 2(a) and (b)(i) of this section, the effect of the distribution is
measured as of the date the indebtedness is distributed; and

(iii) in all other cases, the effect of the distribution is measured as of the
date the distribution is authorized if payment occurs within 120 days after the
date of authorization, or the date the payment is made if it occurs more than
120 days after the date of authorization.

(3) Depositories: The moneys of the corporation shall be deposited in the name
of the corporation in such bank or banks or trust company or trust companies as
the Board of Directors shall designate, and shall be drawn out only by check or
other order for payment of money signed by such persons and in such manner as
may be determined by resolution of the Board of Directors.

ARTICLE VII

Notices

Except as may otherwise be required by law, any notice to any shareholder or
director must be in writing and may be transmitted by: mail, private carrier or
personal delivery; telegraph or teletype; or telephone, wire or wireless
equipment which transmits a facsimile of the notice. Written notice by the
Corporation to its shareholders shall be deemed effective when mailed, if mailed
with first-class postage prepaid and correctly addressed to the shareholder's
address shown in the Corporation's current record of shareholders. Except as set
forth in the previous sentence, written notice shall be deemed effective at the
earliest of the following: (i) when received; (ii) five days after its deposit
in the United States mail, as evidenced by the postmark, if mailed with
first-class postage, prepaid and correctly addressed; or (iii) on the date shown
on the return receipt, if sent by registered or certified mail, return receipt
requested, and receipt is signed by or on behalf of the addressee.

ARTICLE VIII
Seal

The corporate seal of the corporation shall be in such form and bear such
inscription as may be adopted by resolution of the Board of Directors, or by
usage of the officers on behalf of the corporation.

ARTICLE IX

Indemnification

(1) Right to Indemnification: Each person who was or is made a party or is
threatened to be made a party to or is involved (including, without limitation,
as a witness) in any actual or threatened action, suit or proceeding, whether
civil, criminal, administrative or investigative, by reason of the fact that he
or she is or was a director or officer of the corporation or, being or having
been such a director or officer, he or she is or was serving at the request of
the corporation as a director, officer, employee or agent of another corporation
or of a partnership, joint venture, trust or other enterprise, including service
with respect to employee benefit plans, whether the basis of such proceeding is
alleged action in an official capacity as a director, officer, employee or agent
or in any other capacity while serving as a director, officer, employee or
agent, shall be indemnified and held harmless by the corporation to the full
extent permitted by applicable law as then in effect, against all expense,
liability and loss (including attorneys' fees, judgments, fines, ERISA excise
taxes or penalties and amounts to be paid in settlement) actually and reasonably
incurred or suffered by such person in connection therewith and such
indemnification shall continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of his or her heirs,
executors and administrators; provided, however, that except as provided in
Section 2 of this Article with respect to proceedings seeking to enforce rights
to indemnification, the corporation shall indemnify any such person seeking
indemnification in connection with a proceeding (or part thereof) initiated by
such person only if such proceeding (or part thereof) was authorized by the
Board of Directors of the corporation. The right to indemnification conferred in
this Section shall be a contract right and shall include the right to be paid by
the corporation the expenses incurred in defending any such proceeding in
advance of its final disposition; provided, however, that the payment of such
expenses in advance of the final disposition of a proceeding shall be made only
upon delivery to the corporation of an undertaking, by or on behalf of such
director of officer, to repay all amounts so advanced if it shall ultimately be
determined that such director or officer is not entitled to be indemnified under
this Section or otherwise.

(2) Right of Claimant to Bring Suit: If a claim under Section 1 of this Article
is not paid in full by the corporation within sixty days after a written claim
has been received by the corporation, except in the case of a claim for expenses
incurred in defending a proceeding in advance of its final disposition, in which
case the applicable period shall be twenty days, the claimant may at any time
thereafter bring suit against the corporation to recover the unpaid amount of
the claim and, to the extent successful in whole or in part, the claimant shall
be entitled to be paid also the expense of prosecuting such claim. The claimant
shall be presumed to be entitled to indemnification under this Article upon
submission of a written claim (and, in an action brought to enforce a claim for
expenses incurred in defending any proceeding in advance of its final
disposition, where the required undertaking has been tendered to the
corporation) and thereafter the corporation shall have the burden of proof to
overcome the presumption that the claimant is not so entitled. Neither the
failure of the corporation (including its Board of Directors, independent legal
counsel or its shareholders) to have made a determination prior to the
commencement of such action that indemnification of or reimbursement or
advancement of expenses to the claimant is proper in the circumstances nor an
actual determination by the corporation (including its Board of Directors,
independent legal counsel or its shareholders) that the claimant is not entitled
to indemnification or to the reimbursement or advancement of expenses shall be a
defense to the action or create a presumption that the claimant is not so
entitled.

(3) Nonexclusivity of Rights: The right to indemnification and the payment of
expenses incurred in defending a proceeding in advance of its final disposition
conferred in this Article shall not be exclusive of any other right which any
person may have or hereafter acquire under any statute, provision of the
Articles of Incorporation, Bylaws, agreement, vote of shareholders or
disinterested directors or otherwise.

(4) Insurance, Contracts and Funding: The corporation may maintain insurance, at
its expense, to protect itself and any director, officer, employee or agent of
the corporation or another corporation, partnership, joint venture, trust or
other enterprise against any expense, liability or loss, whether or not the
corporation would have the power to indemnify such person against such expense,
liability or loss under the Washington Business Corporation Act. The corporation
may, without further shareholder action, enter into contracts with any director
or officer of the corporation in furtherance of the provisions of this Article
and may create a trust fund, grant a security interest or use other means
(including, without limitation, a letter of credit) to ensure the payment of
such amounts as may be necessary to effect indemnification as provided in this
Article.

(5) Indemnification of Employees and Agents of the Corporation: The corporation
may, by action of its Board of Directors from time to time, provide
indemnification and pay expenses in advance of the final disposition of a
proceeding to employees and agents of the corporation with the same scope and
effect as the provisions of this Article with respect to the indemnification and
advancement of expenses of directors and officers of the corporation or pursuant
to rights granted pursuant to, or provided by, the Washington Business
Corporation Act or otherwise.

ARTICLE X

Books and Records

The corporation shall keep correct and complete books and records of account and
shall keep minutes of the proceedings of its shareholders and Board of
Directors; and shall keep at its registered office or principal place of
business, or at the office of its transfer agent or registrar, a record of its
shareholders, giving the names and addresses of all shareholders in alphabetical
order by class of shares showing the number and class of the shares held by
each. Any books, records, and minutes may be in written form or any other form
capable of being converted into written form within a reasonable time.

ARTICLE XI

Amendments

(1) By Shareholders: These Bylaws may be altered, amended or repealed by the
affirmative vote of a majority of the voting stock issued and outstanding at any
regular or special meeting of the shareholders.

(2) By Directors: The Board of Directors shall have power to make, alter, amend
and repeal the Bylaws of this corporation. However any such Bylaws, or any
alteration, amendment or repeal of the Bylaws, may be changed or repealed by the
holders of a majority of the stock entitled to vote at any shareholders'
meeting.

(3) Emergency Bylaws: The Board of Directors may adopt emergency Bylaws, subject
to repeal or change by action of the shareholders, which shall be operative
during any emergency in the conduct of the business of the corporation resulting
from an attack on the United States or any nuclear or atomic disaster.

Most recently amended by resolution of the corporation's Board of Directors on
October 29, 2003.
