2:00 p.m. Pacific Daylight Time at Data I/O's principal offices, 10525 Willows
Road N.E., Redmond, Washington 98052, and at any adjournment thereof (the
"Annual Meeting"). Shareholders of record at the close of business on March 22,
2004 (the "Record Date") are entitled to notice of and to vote at the Annual
Meeting. This Proxy Statement and a copy of Data I/O's 2003 Annual Report to
Shareholders are being mailed to shareholders on or about April 9, 2004.

A proxy card is enclosed for your use. You are requested on behalf of the Board
of Directors to sign, date, and return the proxy card in the accompanying
envelope, which is postage-paid if mailed in the United States or Canada.

A proxy in the accompanying form, which is properly signed, dated and returned
and not revoked, will be voted in accordance with the instructions contained
therein. To vote on the election of directors, check the appropriate box under
Item No. 1 on your proxy card. You may (a) vote for all of the director nominees
as a group, (b) withhold authority to vote for all director nominees as a group,
or (c) vote for all director nominees as a group except those nominees indicated
to the contrary. To vote on a proposal to amend the Data I/O Corporation 2000
Stock Compensation Incentive Plan (the "2000 Plan") to increase the number of
shares reserved for issuance under the 2000 Plan by an additional 300,000 shares
of common stock, check the appropriate box under Item No. 2 on your proxy card.
You may (a) vote "FOR" approval of the amendment to the 2000 Plan, (b) vote
"AGAINST" approval of the amendment to the 2000 Plan, or (c) "ABSTAIN" from
voting on the approval of the amendment to the 2000 Plan. To vote on the

Data I/O at Data I/O's principal offices, (ii) executing and delivering to Data
I/O another proxy dated as of a later date, or (iii) voting in person at the
Annual Meeting.

VOTING SECURITIES AND PRINCIPAL HOLDERS

The only outstanding voting securities of Data I/O are shares of common stock
(the "Common Stock"). As of the Record Date, there were 8,008,561 of Common
Stock issued and outstanding, and each such share is entitled to one vote at the
Annual Meeting. The presence in person or by proxy of holders of record of a
majority of the outstanding shares of Common Stock is required to constitute a
quorum for the transaction of business at the Annual Meeting. Shares of Common
Stock underlying abstentions will be considered present at the Annual Meeting
for the purpose of calculating a quorum. Under Washington law and Data I/O's
charter documents, if a quorum is present, the seven nominees for election to
the Board of Directors who receive the greatest number of affirmative votes cast
at the Annual Meeting shall be elected directors. Abstentions will have no
effect on the election of directors because they are not cast in favor of any
particular candidate. There can be no broker non-votes on the election of
directors because brokers who hold shares for the accounts of their clients have
discretionary authority to vote such shares with respect to the election of
directors. The proposals to approve the amendment to the 2000 Plan and to ratify
the continued appointment of Grant Thornton as Data I/O's independent auditors
will be approved, if a quorum is present, if the number of votes cast in favor
of the proposals exceeds the number of votes cast against the proposals.
Abstentions and broker non-votes on the proposals will have no effect because
approval of the proposals is based solely on the votes cast. Proxies and ballots
will be received and tabulated by Mellon Investor Services, an independent
business entity not affiliated with Data I/O.

The Common Stock is traded on the NASDAQ SmallCap Stock Market under the symbol
"DAIO". Effective December 31, 2002, the Common Stock transferred from the
NASDAQ National Market to the NASDAQ SmallCap Market. The last sale price for
the Common Stock, as reported by the NASDAQ SmallCap Stock Market on March 22,
2004, was $ 3.02 per share.

The following table sets forth information with respect to all shareholders
known by Data I/O to be the beneficial owners of more than five percent of its
outstanding Common Stock as of March 22, 2004. Except as noted below, each
person or entity has sole voting and investment powers with respect to the

CORPORATE GOVERNANCE

in February 2004, adopted a Nominating Committee Charter, and in March 2004,
adopted an updated Code of Ethics, all of which are posted, together with our
updated charter for the Audit Committee on the corporate governance page of our
website. The corporate governance page can be accessed on our website at
www.dataio.com/corporate/ir.asp. The updated Audit Committee Charter is also
attached to this Proxy Statement as Appendix A. All of these Charters are
consistent with the applicable requirements of the Sarbanes-Oxley Act of 2002
and our NASDAQ listing standards.

Data I/O's Code of Ethics applies to all directors, officers and employees of
Data I/O, including the Chief Executive Officer and the Chief Financial Officer.
The key principles of the Code are to act legally, and with integrity in all
work for Data I/O. We will post any amendments to our Code of Ethics on the
corporate governance page of our website at www.dataio.com/corporate/ir.asp. In
the unlikely event that the Board of Directors approves any sort of waiver to
the Code of Ethics for our executive officers or directors, information
concerning such waiver will also be posted at that location. In addition to
posting information regarding amendments and waivers on our website, the same
information will be included in a Current Report on Form 8-K within five
business days following the date of the amendment or waiver, unless website
posting of such amendments or waivers is permitted by the rules of The NASDAQ
Stock Market, Inc.

PROPOSAL 1: ELECTION OF DIRECTORS

At the Annual Meeting, the shareholders will vote on the election of seven
directors to serve until the next Annual Meeting or until his or her successor
has been qualified and elected or such director's earlier death, resignation or
removal. The Board of Directors has approved the seven nominees named below, all
of whom are currently members of the Board of Directors. Each of the nominees
has indicated that they are willing and able to serve as directors. However,
should one or more of the nominees not accept the nomination, or otherwise be
unwilling or unable to serve, it is intended that the proxies will be voted for
the election of a substitute nominee or nominees designated by the Board of
Directors.

(a)(15) of the National Association of Securities Dealers listing standards (the

Communications with the Board of Directors

Shareholders may communicate with the Board of Directors by sending an email or
by sending a letter to Data I/O Corporation Board of Directors, c/o the
Secretary, P.O. Box 97046, Redmond, WA 98073-9746. The Secretary will receive
the correspondence and forward it to the Chairman of the applicable Board of
Directors Committee or to any individual director or directors to whom the
communication is directed.

BOARD COMMITTEES

During the year ended December 31, 2003, there were four meetings of the Board
of Directors. Each of the incumbent directors who were on the Board of Directors
during 2003 attended at least 75% of the aggregate of the total number of
meetings of the Board of Directors and the total number of meetings held by all
committees of the Board of Directors on which he served during his term of
service on the Board of Directors.

Data I/O does not have a policy requiring members of the Board of Directors to
attend the Annual Meeting, although we typically encourage our Board of
Directors to attend. However, no member of our Board of Directors, except Mr.
Hume, attended our 2003 Annual Meeting because our Board of Directors did not
have a meeting scheduled for that day.

The Board of Directors has four standing Committees: the Corporate Governance
Committee, the Audit Committee, the Compensation Committee, and the Nominating
Committee. The Audit Committee consisted of Messrs. Lazowska, DiLeo (Chair), and
Quist throughout 2003. We added Mr. Walker to the Audit Committee in November
2003. The Compensation Committee consisted of Messrs. Gary, Ceiley (Chair), and
DiLeo throughout 2003. The Nominating Committee consisted of Messrs. Lazowska
(Chair), Gary, and Quist throughout 2003.

Corporate Governance Committee

In April 2003, the Board of Directors created a Corporate Governance Committee
consisting of all independent directors. The Corporate Governance Committee
develops, recommends to the Board of Directors, and monitors a set of corporate
governance principles applicable to Data I/O. The Corporate Governance Committee
met one time in 2003 and otherwise conducted its business at Board of Directors
meetings in 2003.

Audit Committee

The Audit Committee considers and recommends to the Board of Directors the
engagement of independent certified public accountants for the ensuing year and
the terms of such engagement; reviews the scope of the audit; periodically
reviews Data I/O's program of internal control and audit functions; receives and
reviews the reports of the independent accountants; and reviews the annual
financial report to the directors and shareholders of Data I/O. Each member of
the Audit Committee is an independent director, as defined by the NASDAQ listing
standards and the Sarbanes-Oxley Act of 2002. The Audit Committee includes a
financial expert, William R. Walker, as defined in the Securities and Exchange
("SEC") rules adopted pursuant to the Sarbanes-Oxley Act of 2002. Mr. Walker
also has the financial sophistication required by Rule 4350(d)(2) of the NASD
Rules. On February 10, 2003, the Audit Committee recommended and the Board of
Directors amended the charter for the Audit Committee. See attached Appendix B.
The Audit Committee met four times during 2003. See the "Report of the Audit
Committee."

Compensation Committee

The Compensation Committee makes recommendations to the Board of Directors
concerning the compensation of Data I/O's executive officers. The committee
administers Data I/O's management incentive compensation program and its stock
option, stock purchase and stock appreciation rights plans. The Compensation
Committee reviews all employee benefit programs and approves significant changes
in major programs and all new programs. The Compensation Committee met three
times during 2003.

Nominating Committee

The Nominating Committee seeks qualified candidates to serve on the Board of
Directors, recommends them for the Board of Director's consideration for
election as directors at the Annual Meeting of Shareholders and proposes
candidates to fill vacancies on the Board of Directors. The Nominating Committee
also recommends nominees for the various committees of the Board of Directors.
The Nominating Committee met four times in 2003.

Consideration of Director Nominees

The Nominating Committee, in evaluating and determining whether to recommend a
person as a candidate for election as a director, considers relevant management
and/or technology experience; certain values such as integrity, accountability,
judgment and adherence to high performance standards; independence pursuant to
applicable guidelines; ability and willingness to undertake the required time
commitment to Board functions; and an absence of conflicts of interest with
Data I/O.

Identifying Director Nominees; Consideration of Nominees of the Shareholders

The Nominating Committee may employ a variety of methods for identifying and
evaluating nominees for director. The Committee regularly assesses the size of
the Board, the need for particular expertise on the Board, and whether any
vacancies on the Board are expected due to retirement or otherwise. In the event
that vacancies are anticipated, or otherwise arise, the Committee considers
various potential candidates for director which may come to the Committee's
attention through current Board members, professional search firms, shareholders
or other persons. These candidates are evaluated at regular or special meetings
of the Committee, and may be considered at any point during the year.

The Nominating Committee will consider candidates recommended by shareholders,
when the nominations are properly submitted, under the criteria summarized above
in "Consideration of Director Nominees" and in accordance with the procedures
described below in "Shareholder Nominations and Proposals for the 2005 Annual
Meeting of Shareholders." Following verification of the shareholder status of
persons proposing candidates, the Committee makes an initial analysis of the
qualifications of any candidate recommended by shareholders or others pursuant
to the criteria summarized above to determine if the candidate is qualified for
service on the Data I/O Board of Directors before deciding to undertake a
complete evaluation of the candidate. If any materials are provided by a
shareholder or professional search firm in connection with the nomination of a
director candidate, such materials are forwarded to the Committee as part of its
review. Other than the verification of compliance with procedures and
shareholder status, and the initial analysis performed by the Committee, a
potential candidate nominated by a shareholder is treated like any other
potential candidate during the review process by the Committee. Shareholders did
not propose any candidates for election at the 2004 Annual Meeting.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

For the year ended December 31, 2003, the Compensation Committee of the Board of
Directors consisted of Messrs. Gary, DiLeo, and Ceiley. None of these
individuals has served at any time as an officer or employee of Data I/O or as a
member of the board of directors or compensation committee of any entity that
has had one or more executive officers which served as a member of the Board of
Directors or the Compensation Committee.

BOARD COMPENSATION

Employee directors (Frederick R. Hume) do not receive additional compensation
for serving on the Board of Directors. Non-employee directors received a cash
retainer for 2003 of $3,750 for each quarter of service (increased to $5,000 as
of July 1, 2003) plus $1,000 for each full Board of Directors meeting attended
and $500 for each teleconference Board of Directors meeting attended. Data I/O
paid additional quarterly compensation to the non-employee directors for serving
as Chairman of the Board of Directors or as a committee chair: $2,500 (increased
to $3,750 as of July 1, 2003) for Chairman of the Board of Directors; and $750
(increased to $1,250 as of July 1, 2003) for the Audit, Compensation, and
Nominating Committee chairs. The Chairman of the Board serves as the Corporate
Governance Committee Chair and does not receive additional compensation for
chairing such Committee. In addition, each non-employee Board of Directors
member as of May 20, 2003, was granted 7,500 stock options. New members who join
the Board of Directors are granted 15,000 shares as an initial grant. The stock
options were granted under the provisions and terms of the 2000 Plan. Data I/O
also reimburses non-employee directors for actual travel and out-of-pocket
expenses incurred in connection with service to Data I/O.

The following table shows compensation paid by Data I/O to non-employee
directors during 2003.

Section 16(a) of the Securities Exchange Act of 1934 requires Data I/O's
directors, certain officers and persons who own more than ten percent (10%) of
Data I/O's Common Stock ("Reporting Persons") to file with the SEC initial
reports of ownership and reports of changes in ownership of Common Stock and
other equity securities of Data I/O. Reporting Persons are required by SEC
regulations to furnish Data I/O with copies of all Section 16(a) reports.

To Data I/O's knowledge, based solely on its review of copies of such reports
furnished to Data I/O and written representations that no other reports were
required, all Section 16(a) filing requirements applicable to its officers and
directors were complied with during 2003, except Mr. Ceiley filed one report on
Form 4 one day late.

REPORT OF THE AUDIT COMMITTEE

The Audit Committee oversees Data I/O's financial reporting process on behalf of
the Board of Directors. Management has the primary responsibility for the
consolidated financial statements and the reporting process including the
systems of internal controls. Audit Committee members are not professional
accountants, or auditors and their functions are not intended to duplicate or to
certify the activities of management or the independent auditors. In fulfilling
its oversight responsibilities, the Committee reviewed the audited consolidated
financial statements in the Annual Report (Form 10-K) with management including
a discussion of the quality, not just the acceptability, of the accounting
principles, the reasonableness of significant judgments, and the clarity of
disclosures in the financial statements.

The Committee reviewed with the independent auditors, who are responsible for
expressing an opinion on the conformity of those audited consolidated financial
statements with accounting principles generally accepted in the United States,
their judgments as to the quality, not just the acceptability, of Data I/O's
accounting principles and such other matters as are required to be discussed by
SAS 61 with the Committee under generally accepted auditing standards. In
addition, the Committee has discussed with the independent auditors the
auditors' independence from management and Data I/O including the matters in the
written disclosures and the letter provided by the independent auditors as
required by the Independence Standards Board and considered the compatibility of
nonaudit services with the auditors' independence.

The Committee discusses with Data I/O's independent auditors the overall scope
and plans for their respective audits. The Committee meets with the independent
auditors, with and without management present, to discuss the results of their
examinations, their evaluations of Data I/O's internal controls, and the overall
quality of Data I/O's financial reporting. The Committee held four meetings
during 2003.

In reliance on the reviews and discussions referred to above, the Committee
recommended to the Board of Directors (and the Board has approved) that the
audited consolidated financial statements be included in Data I/O's Annual
Report (Form 10-K) for the year ended December 31, 2003 for filing with the
Securities and Exchange Commission. The Committee has selected Grant Thornton
LLP as Data I/O's auditors for the current year.

Policy on Pre-Approval by Audit Committee of Services Performed by Independent
Auditors.

The Audit Committee's policy is to pre-approve all audit and permissible
non-audit services provided by the independent auditors. These services may
include audit services, non-audit services, tax services and other services.
Pre-approval is detailed as to the particular service or category of service and
is subject to a specific engagement authorization.

During the year, circumstances may arise when it may become necessary to engage
the independent auditors for additional services not contemplated in the
original pre-approval. In those circumstances, the Audit Committee has delegated
pre-approval authority to the Chair of the Audit Committee for those instances
when pre-approval is needed prior to a scheduled Audit Committee meeting. These
additional approvals should be reported at the next scheduled Audit Committee
meeting.

For 2003, all services provided by the independent auditors were pre-approved.

REPORT OF COMPENSATION COMMITEE ON ANNUAL COMPENSATION

The Compensation Committee of the Board of Directors (the "Committee") is
composed entirely of independent outside directors. The Committee is responsible
for setting and administering the policies which govern all of the compensation
programs of Data I/O.

The Committee has established a compensation plan for executive officers with
three components: annual base salary, annual management incentive compensation,
and long-term stock options. Each of these components is described below. This
executive officer compensation plan is evaluated annually by the Committee by
reviewing Data I/O's overall financial performance, individual executive officer
performance, and executive officer total compensation compared with other
companies within the electronics industry.

Annual Base Salary Structure. The Committee establishes a base salary structure
for each executive officer position. This structure defines the minimum,
mid-point and maximum salary levels and the relationship of salary to total cash
compensation. The Committee reviews the salary structure periodically based on
surveys of compensation paid to executives performing similar duties with
electronic manufacturing and software companies of approximately the same size
as Data I/O, located primarily in the United States. This group was selected as
it is believed to be representative of the companies with which Data I/O
competes for key employees.

The Committee's objective is to maintain a salary structure which, when combined
with annual incentive compensation, provides Data I/O's executive officers with
total cash compensation which is near the market median for executives with
similar responsibilities, experience and ability. In light of the current
economic situation, we froze executive management salaries at the 2001 level and
deferred consideration of normal annual adjustments as part of Data I/O's
short-term cost control efforts. Due to the salary freeze, no new surveys were
obtained; however in 2001, the executive officer group as a whole received cash
compensation which, according to survey data, was within the 25th to 75th
percentile of the aggregate median cash compensation paid to officers in similar
positions at similar-sized electronics companies.

Management Incentive Compensation Plan ("MICP"). The MICP offers each executive
officer a performance-based opportunity to earn additional annual cash
compensation in an amount tied to a percentage of the executive officer's base
salary. The Committee's objective in setting executive MICP percentages and the
formulas for MICP payout is to pay above industry average total compensation for
better than expected or industry average historical financial performance and
below industry average compensation for worse than expected or industry average
financial historical performance. The percentages of base salary targeted for
MICP payout ("the Guideline") for executives for a given year are established by
the Committee early in the year. The 2003 MICP Guideline for executive officers
was 40% of base salary.

The actual MICP payout to an executive officer, in relation to his Guideline for
2003 was a function of three measures of Data I/O's pre-tax profit: 1) quarterly
profit; 2) growth in annual profit; and 3) record annual profit. The Committee
believes that these measures of key activities for Data I/O during 2003 will
affect near-term and long-term shareholder value. A greater or lesser percentage
of Guideline is to be paid based on Data I/O's actual pre-tax profit.

MICP payouts for 2003 were based on the achievement of a certain level of the
combined measures described above. For 2003, payouts were made for quarterly
profit and growth in annual profit, but not for record profit. Executive
officers received an MICP payout in March 2004 of 54% of Guideline for 2003. See
"Summary Annual Compensation Table"

There were no 2002 payouts. However, based on management's performance in 2002,
the results of the restructuring and the turnaround performance in the difficult
economic environment, Data I/O paid a discretionary bonus of $20,000 to each of
Mr. and Hume and Mr. Hatlen in March 2003.

Stock Option Plan. The Committee approves grants under the Data I/O Corporation
1986 Employee Stock Option Plan, as amended and restated (the "1986 Plan") and
the 2000 Plan (collectively "the Plans"). These are Data I/O's only long-term
incentive plans. The primary purpose of the Plans is to make a significant
element of executive pay a reward for taking actions which maximize shareholder
value over time. The Committee grants options based primarily on its perception
of the executive's ability to affect future shareholder value and secondarily on
the competitive conditions in the market for exceptionally talented executives
who typically command compensation packages which include a significant equity
incentive. All options granted to the President and Chief Executive Officer and
any other executive officer in 2003 were based on these criteria. The Board of
Directors authorized an additional 300,000 shares for the 2000 Employee Stock
Option Plan on February 10, 2004. See also "Proposal 2: Amendment to 2000 Plan."

In the electronics industry, stock options represent a key compensation element
which attracts, retains and motivates exceptional executives. Accordingly, total
outstanding options as a percentage of outstanding shares tends to be higher in
electronics than in other industries. As of the Record Date, Data I/O's
outstanding options represented approximately 16.57% of outstanding shares,
which Data I/O believes is slightly below the average within the electronics
industry.

Historically, all options granted by Data I/O have been granted with an exercise
price equal to the fair market value of Data I/O's Common Stock on the date of
grant and, accordingly, will only have value if Data I/O's stock price
increases. Options granted to employees during 2000, 2001, 2002, and 2003 under
the 2000 Plan become exercisable at a rate of 6.25% per quarter, except for a
50,000 option grant to Mr. Hume as described below. All options granted during
1999, except those granted in January 1999, become exercisable at a rate of 25%
per year. Options granted in January 1999 become exercisable at a rate of 12.5%
per quarter. All 1998 options granted during and after August 1998 become
exercisable at a rate of 12.5% per quarter. All outstanding options granted
prior to August 1998 become exercisable at a rate of 25% per year. Options to
Directors vest quarterly over a 3 year period.

Fifty thousand options granted to Mr. Hume under the 1986 Plan during 2000 are
subject to 4-year cliff vesting and become exercisable at the end of the 4-year
period, with acceleration provisions included for earlier vesting if
predetermined revenue and profit targets are achieved. The targets were not
achieved for 2000, 2001, 2002, or 2003, so none of the acceleration provisions
will apply.

All grants are subject to acceleration of vesting in connection with certain
events leading to a change in control of Data I/O or at any other time at the
discretion of the Committee. All options granted to executive officers are
issued in tandem with limited stock appreciation rights ("SARs"), which become
exercisable only in the event of a change in control of Data I/O. See "Change in
Control and Severance Arrangements."

For additional information concerning the number of new options granted in 2003
to the Chief Executive Officer and other executive officers, see "Option/SAR
Grants in the Last Year."

Performance Evaluation. The base salary of each executive officer is reviewed
annually by the President and Chief Executive Officer. This is done on the basis
of a formal review written by the President and Chief Executive Officer,
evaluating the executive's prior year performance against documented job
responsibilities and specific predetermined annual objectives. In developing
executive compensation packages to recommend to the Committee, the President and
Chief Executive Officer considers, in addition to each executive's prior year
performance, the executive's long-term value to Data I/O, the executive's pay
relative to that for comparable surveyed jobs, the executive's experience and
ability relative to executives in similar positions, and the current year
increases in executive compensation projected in industry surveys.

The Committee then reviews the President and Chief Executive Officer's
recommendations for executive officers' total compensation and makes final
decisions on pay for each executive officer based on the President and Chief
Executive Officer's summary of the performance evaluations and on the other
criteria and survey data described above. In this process, the Committee
consults extensively with Data I/O's President and Chief Executive Officer.

The Committee meets annually without the President and Chief Executive Officer
to evaluate his performance and to develop a recommendation for his compensation
for the coming year. In addition to reviewing Data I/O's financial performance
for the prior year, the Committee reviews compensation surveys for chief
executive officers in similar companies and the President and Chief Executive
Officer's individual performance, including development and execution of short-
and long-term strategic objectives, Data I/O revenue and profitability, and
employee morale, the achievement of which is expected to increase shareholder
value. The Committee then approves base salary and MICP percentage changes for
all executive officers.

The Committee determined the compensation package, including salary, bonus,
stock option grants, and other benefits for Frederick R. Hume, President and
Chief Executive Officer, based on the Committee's perception of his
qualifications for the position, his ability to affect future shareholder value,
compensation surveys (as noted above under "Annual Base Salary Structure"), and
the competitive conditions in the market.

Data I/O has entered into agreements (the "Severance Agreements") with certain
executive officers whereby such individuals would be entitled to receive
payments if they are terminated without cause or resign with good reason within
specified periods following the occurrence of certain events deemed to involve a
change in control of Data I/O. These Severance Agreements expired on January 30,
2004, but may be extended by the Board of Directors. See "Change in Control and
Severance Arrangements." Under the Omnibus Budget Reconciliation Act of 1993,
the federal income tax deduction for certain types of compensation paid to the
chief executive officer and the four other most highly compensated executive
officers of publicly held companies is limited to $1 million per officer per
year unless such compensation meets certain requirements. The Committee is aware
of this limitation and believes that no compensation paid by Data I/O during
2003 will exceed the $1 million limitation, except possibly a portion of the
sums payable pursuant to the Severance Agreements, if paid.

successive quarter after the grant date, with full vesting occurring on the
fourth anniversary of such date. Options which have been outstanding for at
least six months will become exercisable in full upon the occurrence of
certain events leading to a change in control of Data I/O. See "Change in
Control and Severance Arrangements." Options expire six years from the date
of grant, subject to earlier termination if the optionee's employment is

CHANGE IN CONTROL AND SEVERANCE ARRANGEMENTS

Options reported in the Option/SAR compensatory tables appearing above have been
granted pursuant to the Plans. Historically, most options granted under the
Plans have been granted subject to a vesting schedule of either 25% per year,
12.5% per quarter, or 6.25% per quarter. However, the Plans provide that options
which have been outstanding for at least six months will become exercisable in
full for the periods indicated: (i) for a period of 45 days beginning on the day
on which any person or group (with certain exceptions) becomes the beneficial
owner of 25% or more of the combined voting power of Data I/O's outstanding
securities, unless such accumulation is previously approved by a disinterested
majority of the Plan's administrators; (ii) beginning on the date that a tender
or exchange offer by any person (with certain exceptions) is first published or
sent or given, and continuing for so long as such offer remains open, unless,
upon consummation thereof, such person would be the beneficial owner of less
than 30% of the shares of Common Stock then outstanding, unless such tender
offer is approved by a disinterested majority of the Board of Directors; or
(iii) immediately prior to consummation of (a) any merger, consolidation,
reorganization or other transaction pursuant to which persons who hold the
outstanding Common Stock immediately prior to the transaction have less than 40%
of the combined voting power of the surviving entity; or (b) any sale, lease,
exchange or other transfer not in the ordinary course of all or substantially
all of Data I/O's assets. With any of the foregoing transactions, Data I/O will
give each option holder notice 20 days prior to the proposed consummation date,
and each option holder will then be entitled to exercise their options in full
or part at any time prior to consummation of such transaction. A holder's
exercise of those options that become vested only as a result of such
acceleration will be contingent upon consummation of such transaction.

In 1983, Data I/O adopted a SAR Plan which allows the Board of Directors to
grant to each director, executive officer or holder of 10% or more of the stock
of Data I/O a SAR with respect to certain options granted to these parties. A
SAR has been granted in tandem with each option granted to an executive officer
of Data I/O. SARs granted which have been held for at least six months are
exercisable for a period of 20 days following the occurrence of either of the
following events: (i) the close of business on the day that a tender or exchange
offer by any person (with certain exceptions) is first published or sent or
given if, upon consummation thereof, such person would be the beneficial owner
of 30% or more of the shares of Common Stock then outstanding; or (ii) approval
by the shareholders of Data I/O (or, if later, approval by the shareholders of a
third party) of any merger, consolidation, reorganization or other transaction
providing for the conversion or exchange of more than 50% of the outstanding
shares of Data I/Os Common Stock into securities of a third party, or cash, or
property, or a combination of any of the foregoing.

Data I/O entered into severance agreements (the "Severance Agreements") with
each of the following executive officers on the following dates: Joel S. Hatlen,
Vice President Finance, Chief Financial Officer, Secretary and Treasurer in July
1998 and Frederick R. Hume, President and Chief Executive Officer in February
1999, the term of these agreements were extended on January 31, 2002 for a
period of 2 years from that date. These Severance Agreements expired on January
30, 2004, but these agreements may be extended again by the Board of Directors.
The respective agreements with Messrs. Hatlen and Hume provided for a lump sum
payment to the officer upon termination of the officer's employment by Data I/O
without cause or by the officer for "good reason" (as defined in the Severance
Agreements) 90 days prior and within one year following a change of control of
Data I/O. The amount of the lump sum payment is equal to a multiple of the
officer's base salary at the time of termination, plus the average bonus
received during the last three full years the officer served in his or her
present position (the "base"). The guideline for the multiple for each of the
officers is one times the base. The size of the multiple declines on a
straight-line basis throughout the specified period, following a change in
control, except that the multiple is never less than one-half. The amount
payable under the Severance Agreements for Messrs. Hatlen and Hume is subject to
reduction if the aggregate present value of all payments received in connection
with a change in control would exceed three times the officer's "annualized
includible compensation", as defined in Section 280G of the Internal Revenue
Code, for the executive officer's most recent five taxable years.

In connection with execution of the Severance Agreements, Data I/O required
Messrs. Hatlen and Hume to sign a confidentiality and non-competition agreement,
which includes, among other things, a restriction against competing with Data
I/O or soliciting employees from Data I/O for a one-year period following
termination if the officer receives a payment under a Severance Agreement. The
Board of Directors believes that the terms and conditions of the Severance
Agreements are in the best interest of Data I/O because the Severance Agreements
will enable the executive officers to continue to focus on activities providing
for the maximum long-term value to Data I/O's shareholders, even when faced with
the possible change of control of Data I/O or termination of their employment.
In addition, each of the executive officers named in the Summary Compensation
Table have signed Data I/O's form of offer letter and have entered into a
Confidentiality and Intellectual Property Assignment Agreement (the
"Confidentiality Agreement") with Data I/O. These offer letters specify the
terms of employment, including annual base pay, MICP participation, stock
options provided, if any, and that employment is at will. The Confidentiality
Agreements also provide that employment is at will. The Confidentiality
Agreements also provide that executive officers shall keep certain information
confidential during and after employment and shall not solicit employees of Data
I/O for one year following termination of their employment.

PROPOSAL 2: AMENDMENT TO 2000 PLAN

At the Annual Meeting, the shareholders of Data I/O will be asked to approve an
amendment to the 2000 Plan, which, if approved, will increase the number of
shares of Common Stock available for grant under the 2000 Plan by an additional
300,000 shares, to an aggregate of 1,883,558 shares, the fair market value of
such securities is $5,688,345 as of March 22, 2004. As of March 22, 2004, Data
I/O has outstanding options with respect to 1,320,085 shares of Common Stock and
263,473 shares of Common Stock available for grants. Approval of the proposed
increase will also be deemed a ratification of the terms of the 2000 Plan, as
amended.

The Board of Directors believes that the 2000 Plan has contributed to
strengthening the incentive of participating employees to achieve the objectives
of Data I/O and its shareholders by encouraging employees to acquire a greater
proprietary interest in Data I/O. The Board of Directors believes that
additional shares must be reserved for use under the 2000 Plan to enable Data
I/O to attract and retain key employees through the granting of options under
the 2000 Plan. The proposed increase in the number of shares reserved under the
2000 Plan is not required or intended to cover awards previously made under the
2000 Plan. As such, no new plan benefits have been granted to date, and future
awards under the 2000 Plan are not yet determinable.

The affirmative vote of at least a majority of the shares of Common Stock
present in person or represented by proxy at the 2004 Annual Meeting and
entitled to vote on the proposal is required for approval of the amendment to
the 2000 Plan. The Board of Directors recommends a vote FOR approval of the
proposed amendment to the 2000 Plan. Unless instructed otherwise, it is the
intention of the persons named in the accompanying form of proxy to vote shares
represented by properly executed proxies in favor of the above-referenced
amendment to the 2000 Plan.

Description of the 2000 Plan

The following description of the 2000 Plan is qualified in its entirety by
reference to the full text of such Plan, a copy of which is attached to this
Proxy Statement as Appendix A. The purpose of the 2000 Plan is to enhance the
long-term shareholder value of Data I/O by offering opportunities to employees,
persons to whom offers of employment have been extended, directors, officers,
consultants, agents, advisors and independent contractors of Data I/O and its
subsidiaries to participate in Data I/O's growth and success, and to encourage
them to remain in the service of Data I/O and its subsidiaries and to acquire
and maintain stock ownership in Data I/O. The 2000 Plan may be administered
either by the Board of Directors or a committee or committees appointed by (in
either case, the "Committee"), and consisting of two or more members of, the
Board of Directors. The Committee will have broad discretion to determine the
amount and type of awards and terms and conditions of the awards. Individual
grants will generally be based on a person's present and potential contribution
to Data I/O.

As of March 22, 2004, Data I/O had approximately 127 employees and 6
non-employee directors who would be eligible to participate in the 2000 Plan.
Consultants, agents, advisors, and independent contractors could be eligible
under the 2000 Plan; however, Data I/O has no outstanding grants to this group.
Because the grant of awards is based upon a determination made by the Committee
after a consideration of various factors, Data I/O currently cannot determine
the nature and amount of any awards that will be granted in the future to any
eligible individual or group of individuals. However, the maximum number of
shares that can be granted under the 2000 Plan during any calendar year to any
executive officer whose compensation is required to be disclosed pursuant to the
rules and regulations under the Securities Exchange Act of 1934, as amended,
(generally, the chief executive officer and the four other most highly
compensated executive officers) is 200,000, except that Data I/O may make
additional one-time grants to newly hired participants of up to 100,000 shares
per such participant. In addition, the maximum number of shares that can be
granted to a non-employee director of Data I/O during any calendar year is
limited to 100,000. Data I/O believes that with these limitations and other
provisions of the 2000 Plan, options granted under the 2000 Plan will generate
"qualified performance-based compensation" within the meaning of Section 162(m)
of the Internal Revenue Code and will, therefore, not be subject to the
$1,000,000 cap on deductibility for federal income tax purposes of certain
compensation payments in excess of $1,000,000. See "Certain Federal Income Tax
Consequences" below.

Awards may be granted in the form of incentive stock options ("ISOs") within the
meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code"), nonqualified stock options ("NQOs") (each ISO or NQO, an "Option" and
collectively, "Options"), stock appreciation rights, stock awards in the form of
restricted stock ("Restricted Stock"), or other arrangements determined by the
Committee. Any award may be granted either alone or in tandem with other awards
granted under the 2000 Plan. The option price of ISOs shall be as determined by
the Committee, but shall not be less than 100% of the fair market value of the
Common Stock on the grant date. The option price of NQOs may be less than the
fair market value of the Common Stock on the date of the grant. The Committee
may condition the grant of the award upon the attainment of specified
performance goals or other criteria, which need not be the same for all
participants. No ISOs may be granted under the 2000 Plan on or after May 19,
2010, but ISOs outstanding under the 2000 Plan may extend beyond that date.

Options. Options granted under the 2000 Plan may be ISOs or NQOs. The exercise
price of ISOs may not be less than the fair market value of the shares subject
to the ISO on the date of grant. The term of any ISO granted under the 2000 Plan
may not exceed ten years. In addition, ISOs are subject to certain other
limitations in order to take advantage of the favorable U.S. tax treatment that
may be available for ISOs.

Restricted Stock. Restricted Stock awards consist of non-transferable shares of
Common Stock of Data I/O which may be subject to a right of purchase by Data
I/O. The Committee may provide for the lapse of the transfer restrictions over a
period of time, or may accelerate or waive such restrictions, in whole or in
part, based on service, performance or other criteria determined by the
Committee.

Stock Appreciation Rights. A stock appreciation right will give the holder the
right to receive an appreciation distribution in an amount equal to the excess
of the fair market value of the number of shares of Common Stock covered by the
right over the exercise price per share subject to the right. Stock appreciation
rights may be granted separately or in tandem with a related Option. Payment may
be made in a combination of shares of Common Stock or in cash, as determined by
the Committee.

The consideration payable upon issuance or exercise of an award and any taxes
related to an award must generally be paid in cash or check. However, the
Committee, in its sole discretion, may, either at the time the Option is granted
or at any time before it is exercised and subject to such limitations as the
Committee may determine, authorize payment by the tender of Common Stock already
owned by the participant for at least six months having a fair market value on
the day prior to the exercise date equal to the aggregate Option exercise price,
by delivery of a promissory note, by delivery of a properly executed exercise
notice, together with irrevocable instruction (i) to a third-party designated by
Data I/O to deliver to Data I/O the amount of sale or loan proceeds to pay the
exercise price and withholding tax obligations and (ii) to Data I/O to deliver
the certificates for such shares to the third-party, or by such other
consideration as the Committee may permit. In addition, to assist a holder of
award (including a holder who is an officer or director of Data I/O) in
acquiring shares of Common Stock pursuant to an award granted under the 2000
Plan, the Committee, in its sole discretion, may authorize, either at the grant
date or at any time before the acquisition of Common Stock pursuant to the
award, the extension of a loan to the holder by Data I/O, the payment by the
holder of the purchase price, if any, of the Common Stock in installments, or
the guarantee by Data I/O of a loan obtained by the grantee from a third-party.
Awards generally may be exercised at any time within three months after
termination of a participant's employment by, or consulting relationship with,
Data I/O (but, only to the extent exercisable or payable at the time of
termination). However, if termination is due to the participant's death or
disability, the award generally may be exercised for one year. Except as
authorized by the Committee, no award shall be assignable or otherwise
transferable by a participant other than by will or by the laws of descent and
distribution.

The Committee may adjust the performance goals and measurements applicable to
awards. The Committee also may waive in whole or in part any or all
restrictions, conditions, vesting or forfeiture with respect to any award
granted under the 2000 Plan. The Board of Directors may amend, alter or
discontinue the 2000 Plan or any award at any time, except that the consent of a
participant is required if the participant's rights under an outstanding award
would be impaired. In addition, the shareholders of Data I/O must approve any
amendment, alteration or discontinuance of the 2000 Plan that would (i) increase
the total number of shares reserved under the 2000 Plan, (ii) with respect to
provisions solely as they relate to ISOs, to the extent required for the 2000
Plan to comply with Section 422 of the Code, (iii) to the extent required by
other applicable laws, rules or regulations or (iv) to the extent that the Board
of Directors otherwise concludes that shareholder approval is advisable.

The 2000 Plan constitutes an unfunded plan for incentive and deferred
compensation. Data I/O is not required to create trusts or arrangements to meet
its obligations under the 2000 Plan to deliver stock or make payments.

In the event of a "change in control" of Data I/O, as defined in the 2000 Plan,
in which the outstanding options do not remain outstanding or are not assumed by
the surviving entity or replaced with comparable options, the vesting of
outstanding "qualifying" awards under the 2000 Plan will, unless the applicable
agreement with respect to the award or the Committee determines otherwise,
subject to certain limitations, be accelerated in full. If outstanding options
remain outstanding after a change of control or are assumed by the surviving
entity or replaced with comparable options, subject to certain limitations, the
vesting of outstanding "qualifying" options will be accelerated to the extent of
25% of the unvested portion thereof and the vesting of outstanding "qualifying"
restricted stock awards will be accelerated to the extent of 25% of the unvested
portion thereof. Further, if the holder of any "qualifying" award which remains
outstanding or is assumed by the surviving entity in a change of control
transaction is terminated involuntarily within 180 days of the change of
control, the vesting of all options and other awards held by such person will be
accelerated in full. A "qualifying" award is defined as an option or award that
has been held for at least 180 days as of the change of control. A "change in
control" is defined to include (i) a merger or consolidation of Data I/O in
which more than 50% of the voting power of Data I/O's outstanding stock
outstanding after the transaction is owned by persons who are not shareholders
immediately prior to such transaction, and (ii) the sale or transfer of all or
substantially all of Data I/O's assets.

Certain Federal Income Tax Consequences

THE FOLLOWING SUMMARY OF FEDERAL INCOME TAX CONSEQUENCES IS BASED UPON EXISTING
STATUTES, REGULATIONS AND INTERPRETATIONS THEREOF. THE APPLICABLE RULES ARE
COMPLEX, AND INCOME TAX CONSEQUENCES MAY VARY DEPENDING UPON THE PARTICULAR
CIRCUMSTANCES OF EACH PLAN PARTICIPANT. THIS PROXY STATEMENT DESCRIBES FEDERAL
INCOME TAX CONSEQUENCES OF GENERAL APPLICABILITY, BUT DOES NOT PURPORT TO
DESCRIBE PARTICULAR CONSEQUENCES TO EACH INDIVIDUAL PLAN PARTICIPANT, OR
FOREIGN, STATE OR LOCAL INCOME TAX CONSEQUENCES, WHICH MAY DIFFER FROM THE
UNITED STATES FEDERAL INCOME TAX CONSEQUENCES.

Incentive Stock Options

Awards and Exercise of Options. ISOs are intended to constitute "incentive stock
options" within the meaning of Section 422 of the Code. ISOs may be granted only
to employees of Data I/O (including directors who are also employees). The
recipient of an Option (the "Optionee") does not recognize taxable income upon
either the grant or exercise of an ISO. However, the excess of the fair market
value of the shares purchased upon exercise over the Option exercise price (the
"Option Spread") is includable in the Optionee's "alternative minimum taxable
income" ("AMTI") for purposes of the alternative minimum tax ("AMT"). The
Option Spread is generally measured on the date of exercise and is includable in
AMTI in the year of exercise. Special rules regarding the time of AMTI inclusion
may apply for shares subject to a "substantial risk of forfeiture" (including,
in the case of each person subject to the reporting requirements of Section
16(b) of the Exchange Act). In addition, when stock is acquired subject to a
"substantial risk of forfeiture", an Optionee's holding period for purposes of
determining whether any capital gain or loss on sale is long-term will generally
not begin until the restriction lapses or the Optionee files an election under
Section 83(b) of the Code (a "Section 83(b) Election").

Sale of Option Shares. If an Optionee holds the shares purchased under an ISO
for at least two years from the date the ISO was granted and for at least one
year from the date such shares where transferred to the Optionee, any gain from
a sale of the shares other than to Data I/O should be taxable as capital gain.
Under these circumstances, Data I/O would not be entitled to a tax deduction at
the time the ISO was exercised or at the time the stock was sold. If an Optionee
were to dispose of stock acquired pursuant to an ISO before the end of the
required holding periods (a "Disqualifying Disposition"), the amount by which
the market value of the stock at the time the ISO was exercised exceeded the
exercise price (or, if less, the amount of gain realized on the sale) would be
taxable as ordinary income, and Data I/O would be entitled to a corresponding
tax deduction. Such income is subject to information reporting requirements and
may become subject to withholding. Gain from a Disqualifying Disposition in
excess of the amount required to be recognized as ordinary income is capital
gain. Optionees are required to notify Data I/O promptly after making a
Disqualifying Disposition. If the stock is sold to Data I/O rather than to a
third party, the sale may not produce capital gain or loss. A sale of shares to
Data I/O will constitute a redemption of such shares, which could be taxable as
a dividend unless the redemption is "not essentially equivalent to a dividend"
within the meaning of the Code.

Exercise With Stock. If an Optionee pays for ISO shares with shares of Data I/O
acquired under an ISO or a qualified employee stock purchase plan ("Statutory
Option Stock"), the tender of shares is a Disqualifying Disposition of the
Statutory Option Stock if the above described (or other applicable) holding
periods respecting those shares have not been satisfied. If the holding periods
with respect to the Statutory Option Stock are satisfied, or the shares were not
acquired under a statutory stock option of Data I/O, then any appreciation in
value of the surrendered shares is not taxable upon surrender. Special basis and
holding period rules apply where previously-owned stock is used to exercise an
ISO.

Nonqualified Stock Options

Awards and Exercise of Options. An Optionee is not taxable upon the award of an
NQO. Federal income tax consequences upon exercise will depend upon whether the
shares thereby acquired are subject to a "substantial risk of forfeiture". If
the shares are not subject to a "substantial risk of forfeiture", or if they are
so restricted and the Optionee files a Section 83(b) Election with respect to
the shares, the Optionee will have ordinary income at the time of exercise
measured by the Option Spread on the exercise date. The Optionee's tax basis in
the shares will be their fair market value on the date of exercise, and the
holding period for purposes of determining whether capital gain or loss upon
sale is long- or short-term also will begin on that date. If the shares are
subject to a "substantial risk of forfeiture" and no Section 83(b) Election is
filed, the Optionee will not be taxable upon exercise, but instead will have
ordinary income on the date the stock is no longer subject to a "substantial
risk of forfeiture", in an amount equal to the difference between the amount
paid for the shares under the Option and their fair market value as of the date
of lapse; in addition, the Optionee's holding period will begin on the date of
lapse.

Whether or not the shares are subject to a "substantial risk of forfeiture", the
amount of ordinary income taxable to an Optionee who was an employee at the time
of grant constitutes "supplemental wages" subject to a withholding of income and
employment taxes by Data I/O, and Data I/O receives a corresponding income tax
deduction.

Sale of Option Shares. Upon sale, other than to Data I/O, of shares acquired
under a NQO, an Optionee generally will recognize capital gain or loss to the
extent of the difference between the sale price and the Optionee's tax basis in
the shares, which will be long-term gain or loss if the employee's holding
period in the shares is more than one year. If the stock is sold to Data I/O
rather than to a third party, the sale may not produce capital gain or loss. A
sale of shares to Data I/O will constitute a redemption of such shares, which
could be taxable as a dividend unless the redemption is "not essentially
equivalent to a dividend" within the meaning of the Code.

Exercise With Stock. If an Optionee tenders Common Stock (other than Statutory
Option Stock - see above) to pay all or part of the exercise price of a NQO, the
Optionee will not have a taxable gain or deductible loss on the surrendered
shares. Instead, shares acquired upon exercise that are equal in value to the
fair market value of the shares surrendered in payment are treated as if they
had been substituted for the surrendered shares, taking as their basis and
holding period the basis and holding period that the Optionee had in the
surrendered shares. The additional shares are treated as newly acquired with a
zero basis.

If the surrendered shares are Statutory Option Stock as described above under
"Incentive Stock Options", with respect to which the applicable holding period
requirements for favorable income tax treatment have not expired, then the newly
acquired shares substituted for the Statutory Option Shares should remain
subject to the federal income tax rules governing the surrendered shares, but
the surrender should not constitute a Disqualifying Disposition of the
surrendered stock.

PROPOSAL 3: RATIFICATION OF THE CONTINUED APPOINTMENT OF AUDITORS

The Board of Directors requests that the shareholders ratify the continued
appointment of Grant Thornton LLP to serve as Data I/O's independent auditors
for calendar year 2004. Grant Thornton LLP examined the consolidated financial
statements of Data I/O for the year ended December 31, 2003. Representatives of
Grant Thornton LLP will be present at the Annual Meeting to make a statement if
they desire to do so and to respond to questions by shareholders.

OTHER BUSINESS

As of the date of this Proxy Statement, Data I/O is not aware of any other
business to be acted upon at the Annual Meeting. If any other business calling
for a vote of the shareholders is properly presented at the meeting, the holders
of the proxies will vote or refrain from voting in accordance with their best
judgment.

SHAREHOLDER NOMINATIONS AND PROPOSALS FOR THE
2005 ANNUAL MEETING OF SHAREHOLDERS

Data I/O's Bylaws provide that advance notice of nominations for the election of
directors at a meeting of shareholders must be delivered to or mailed and
received by Data I/O on or before by February 19, 2005 in the case of an annual
meeting of shareholders, and in the case of a special meeting of shareholders to
elect directors, the close of business on the 10th day following the date on
which notice of such meeting is first given to shareholders. The Bylaws also
provide that advance notice of proposals to be brought before an Annual Meeting
by a shareholder must be submitted in writing and delivered to or mailed and
received by Data I/O not later than 90 days prior to the date one year from the
date immediately preceding the Annual Meeting of Shareholders.

To qualify as an "eligible" shareholder, a shareholder must have been a record
or beneficial owner of at least one percent (1%) of Data I/O's outstanding
Common Stock, or shares of Common Stock having a market value of at least
$2,000, for a period of at least one (1) year prior to submitting the proposal,
and the shareholder must continue to hold the shares through the date on which
the meeting is held.

Each notice of a nomination or proposal of business must contain, among other
things: (i) the name and address of the shareholder who intends to make the
nomination or proposal; (ii) a representation that the shareholder is a holder
of record of stock of Data I/O 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 or to vote at the meeting for the proposal; (iii) 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 and any material interest of such shareholder in any proposal to be
submitted to the meeting; (iv) such other information regarding each nominee or
proposal as would be required to be included in a proxy statement filed pursuant
to the proxy rules of the SEC; and (v) with respect to the nominations, the
consent of each nominee to serve as a director of Data I/O if elected.

A copy of the full text of the provisions of Data I/O's Bylaws dealing with
shareholder nominations and proposals is available to shareholders from the
Secretary of Data I/O upon written request.

SEC rules establish a deadline for submission of shareholder proposals that are
not intended to be included in Data I/O's proxy statement with respect to
discretionary voting (the "Discretionary Vote Deadline"). The Discretionary Vote
Deadline for the 2005 Annual Meeting is February 19, 2005. If a shareholder
gives notice of such a proposal after the Discretionary Vote Deadline, Data
I/O's proxy holders will be allowed to use their discretionary voting authority
to vote against the shareholder proposal when and if the proposal is raised at
the 2005 Annual Meeting.

Shareholders who intend to have a proposal considered for inclusion in Data
I/O's proxy materials for presentation at the 2005 Annual Meeting must submit
the proposal to Data I/O no later than December 2, 2004. Shareholders who intend
to present a proposal at the 2004 Annual Meeting without inclusion of such
proposal in Data I/O's proxy materials are required to provide notice of such
proposal to Data I/O no later than February 19, 2005. Data I/O reserves the
right to reject, rule out of order, or take appropriate action with respect to
any proposal that does not comply with these and other applicable requirements,
but only after Data I/O has notified the shareholder(s) who have submitted the
proposal of the problem and such shareholder(s) have failed to correct it. This
obligation to notify the appropriate shareholder(s) does not apply to the
failure to submit such proposal prior to the deadlines discussed above.

SOLICITATION OF PROXIES

The proxy accompanying this Proxy Statement is solicited by the Board of
Directors. Proxies may be solicited by officers, directors and regular
supervisory and executive employees of Data I/O, none of whom will receive any
additional compensation for their services. In addition, Data I/O may engage an
outside proxy solicitation firm to render proxy solicitation services and, if
so, will pay a fee for such services. Solicitations of proxies may be made
personally, or by mail, telephone, telegraph or messenger. Data I/O will pay
persons holding shares of Common Stock in their names or in the names of
nominees, but not owning such shares beneficially, such as brokerage houses,
banks and other fiduciaries, for the expense of forwarding soliciting materials
to their principals. All costs of solicitation of proxies will be paid by Data
I/O.

(which term includes subcommittees) appointed by, and consisting of two or more
members of, the Board. Any such committee shall have the powers and authority
vested in the Board hereunder (including the power and authority to interpret
any provision of the Plan or of any Award). The Board, or any committee thereof
appointed to administer the Plan, is referred to herein as the "Plan
Administrator." If and so long as the Common Stock is registered under Section
12(b) or 12(g) of the Exchange Act, the Board shall consider in selecting the
Plan Administrator and the membership of any committee acting as Plan
Administrator for any persons subject or likely to become subject to Section 16
under the Exchange Act the provisions regarding (a) "outside directors" as
contemplated by Section 162(m) of the Code and (b) "Non-Employee Directors" as
contemplated by Rule 16b-3 under the Exchange Act. The Board or Plan
Administrator may delegate the responsibility for administering the Plan with
respect to designated classes of eligible Participants to one or more senior
executive officers or committees thereof, the members of which need not be
members of the Board, subject to such limitations as the Board deems
appropriate. Committee members shall serve for such term as the Board may
determine, subject to removal by the Board at any time.

3.2 Administration and Interpretation by the Plan Administrator.

Except for the terms, conditions and limitations explicitly set forth in
the Plan, the Plan Administrator shall have exclusive authority, in its absolute
discretion, to determine all matters relating to Awards under the Plan,
including the selection of individuals to be granted Awards, the type of Awards,
the number of shares of Common Stock subject to an Award, all terms, conditions,
restrictions and limitations, if any, of an Award and the terms of any
instrument that evidences the Award. The Plan Administrator shall also have
exclusive authority to interpret the Plan and may from time to time adopt,
change and rescind rules and regulations of general application for the Plan's
administration. This authority shall include the sole authority to correct any
defect, supply any omission or reconcile any inconsistency in this Plan and make
all other determinations necessary or advisable for the administration of the
Plan and do everything necessary or appropriate to administer the Plan. The Plan
Administrator's interpretation of the Plan and its rules and regulations, and
all actions taken and determinations made by the Plan Administrator pursuant to
the Plan, shall be conclusive and binding on all parties involved or affected.
The Plan Administrator may delegate administrative duties to such of Data I/O's
officers as it so determines.

4. STOCK SUBJECT TO THE PLAN

4.1 Authorized Number of Shares.

As of March 10, 2000, Data I/O has outstanding options with respect to
1,215,000 shares of Common Stock and 270,499 shares of Common Stock available
for additional grants under the 2000 Plan and the Data I/O 1986 Employee Stock
Option Plan ("1986 Plan"). Subject to adjustment from time to time as provided
in Section 14.1, Awards of the authorized but unissued shares of Common Stock
under the 1986 Plan, or shares of Common Stock that become available under the
1986 Plan as a result of the expiration or termination of options, may be
granted under this Plan. Awards for an additional 300,000 shares of Common Stock
shall also be available for issuance under the Plan. Shares issued under the
Plan shall be drawn from authorized and unissued shares. See also Section 18 for
Plan amendments.

4.2 Limitations.

(a) Subject to adjustment from time to time as provided in Section 14.1,
not more than 200,000 shares of Common Stock may be made subject to Awards under
the Plan to any individual Participant in the aggregate in any one (1) calendar
year, except that Data I/O may make additional one-time grants to newly hired
Participants of up to 100,000 shares per such Participant; such limitation shall
be applied in a manner consistent with the requirements of, and only to the
extent required for compliance with, the exclusion from the limitation on
deductibility of compensation under Section 162(m) of the Code.

(b) Subject to adjustment from time to time as provided in Section 14.1,
not more than 100,000 shares of Common Stock may be made subject to Awards to
any non-employee director in the aggregate in any one calendar year. 4.3 Reuse
of Shares.

Any shares of Common Stock that have been made subject to an Award that
cease to be subject to the Award (other than by reason of exercise or payment of
the Award to the extent it is exercised for or settled in shares) and any shares
repurchased by Data I/O from a Holder upon exercise of a right of repurchase
shall again be available for issuance in connection with future grants of Awards
under the Plan; provided, however, that any such shares shall be counted in
accordance with the requirements of Section 162(m) of the Code of Ethics if and
to the extent applicable. Shares that are subject to tandem Awards shall be
counted only once. Also, upon a stock-for-stock exercise only the net number of
shares will be deemed to have been used under this Plan.

5. ELIGIBILITY

Awards may be granted under the Plan to those officers, directors and key
employees of Data I/O and its Subsidiaries as the Plan Administrator from time
to time selects. Awards may also be made to consultants, agents, advisors and
independent contractors who provide services to Data I/O and its Subsidiaries.

6. AWARDS

6.1 Form and Grant of Awards.

The Plan Administrator shall have the authority, in its sole discretion, to
determine the type or types of Awards to be made under the Plan. Such Awards may
include, but are not limited to, Incentive Stock Options, Nonqualified Stock
Options, Stock Appreciation Rights, Stock Awards and Other Stock-Based Awards.
Awards may be granted singly, in combination or in tandem so that the settlement
or payment of one automatically reduces or cancels the other. Awards may also be
made in combination or in tandem with, in replacement of, as alternatives to, or
as the payment form for, grants or rights under any other employee or
compensation plan of Data I/O.

6.2 Acquired Company Awards.

Notwithstanding anything in the Plan to the contrary, the Plan
Administrator may grant Awards under the Plan in substitution for awards issued
under other plans, or assume under the Plan awards issued under other plans, if
the other plans are or were plans of other acquired entities ("Acquired
Entities") (or the parent of the Acquired Entity) and the new Award is
substituted, or the old Award is assumed, by reason of a merger, consolidation,
acquisition of property or of stock, reorganization or liquidation (an
"Acquisition Transaction"). If a written agreement pursuant to which an
Acquisition Transaction is completed is approved by the Board and said agreement
sets forth the terms and conditions of the substitution for or assumption of
outstanding awards of the Acquired Entity, said terms and conditions shall be
deemed to be the action of the Plan Administrator without any further action by
the Plan Administrator, except as may be required for compliance with Rule 16b-3
under the Exchange Act, and the persons holding such Awards shall be deemed to
be Participants and Holders.

7. AWARDS OF OPTIONS

7.1 Grant of Options.

The Plan Administrator is authorized under the Plan, in its sole
discretion, to issue Options as Incentive Stock Options or as Nonqualified Stock
Options, which shall be appropriately designated.

7.2 Option Exercise Price.

The exercise price for shares purchased under an Option shall be as
determined by the Plan Administrator, but shall not be less than 100% of the
Fair Market Value of the Common Stock on the Grant Date with respect to
Incentive Stock Options.

7.3 Term of Options.

The term of each Option shall be as established by the Plan Administrator
or, if not so established, shall be six (6) years from the Grant Date.

7.4 Exercise of Options.

The Plan Administrator shall establish and set forth in each instrument
that evidences an Option the time at which or the installments in which the
Option shall become exercisable, which provisions may be waived or modified by
the Plan Administrator at any time. If not so established in the instrument
evidencing the Option or otherwise set at the time of grant, the Option will be
subject to the following: (a) 25% of the Option shall vest and become
exercisable on each anniversary of the Grant Date such that the Option shall be
fully vested on the fourth anniversary of the Grant Date; (b) in no event shall
any additional Option Shares vest after termination of Holder's employment by or
service to Data I/O; and (c) the Plan Administrator may waive or modify the
foregoing schedule at any time.

To the extent that the right to purchase shares has accrued thereunder, an
Option may be exercised from time to time by written notice to Data I/O, in
accordance with procedures established by the Plan Administrator, setting forth
the number of shares with respect to which the Option is being exercised and
accompanied by payment in full as described in Section 7.5. An Option may not be
exercised as to less than 100 shares at any one time (or the lesser number of
remaining shares covered by the Option).

7.5 Payment of Exercise Price.

The exercise price for shares purchased under an Option shall be paid in
full to Data I/O by delivery of consideration equal to the product of the Option
exercise price and the number of shares purchased. Such consideration must be
paid in cash or check (unless, at the time of exercise, the Plan Administrator
determines not to accept a personal check), except that the Plan Administrator,
in its sole discretion, may, either at the time the Option is granted or at any
time before it is exercised and subject to such limitations as the Plan
Administrator may determine, authorize payment in cash and/or one or more of the
following alternative forms: (a) tendering (either actually or, if and so long
as the Common Stock is registered under Section 12(b) or 12(g) of the Exchange
Act, by attestation) Common Stock already owned by the Holder for at least six
months (or any shorter period necessary to avoid a charge to Data I/O's earnings
for financial reporting purposes) having a Fair Market Value on the day prior to
the exercise date equal to the aggregate Option exercise price; (b) a promissory
note delivered pursuant to Section 12; (c) if and so long as the Common Stock is
registered under Section 12(b) or 12(g) of the Exchange Act, delivery of a
properly executed exercise notice, together with irrevocable instructions, to
(i) a third party designated by Data I/O to deliver promptly to Data I/O the
aggregate amount of sale or loan proceeds to pay the Option exercise price and
any withholding tax obligations that may arise in connection with the exercise
and (ii) Data I/O to deliver the certificates for such purchased shares directly
to such third party, all in accordance with the regulations of the Federal
Reserve Board; or (d) such other consideration as the Plan Administrator may
permit.

7.6 Post-Termination Exercises.

The Plan Administrator may establish and set forth in each instrument that
evidences an Option whether the Option will continue to be exercisable, and the
terms and conditions of such exercise, if a Holder ceases to be employed by, or
to provide services to, Data I/O or its Subsidiaries, which provisions may be
waived or modified by the Plan Administrator at any time.

If not so established in the instrument evidencing the Option, the Option
will be exercisable according to the following terms and conditions, which may
be waived or modified by the Plan Administrator at any time.

In case of termination of the Holder's employment or services other than by
reason of death or Cause, the Option shall be exercisable, to the extent of the
number of shares purchasable by the Holder at the date of such termination, only
(a) within one (1) year if the termination of the Holder's employment or
services are coincident with Disability or (b) within three (3) months after the
date the Holder ceases to be an employee, director, officer, consultant, agent,
advisor or independent contractor of Data I/O or a Subsidiary if termination of
the Holder's employment or services is for any reason other than death or
Disability, but in no event later than the remaining term of the Option. Any
Option exercisable at the time of the Holder's death may be exercised, to the
extent of the number of shares purchasable by the Holder at the date of the
Holder's death, by the personal representative of the Holder's estate entitled
thereto at any time or from time to time within one (1) year after the date of
death, but in no event later than the remaining term of the Option. In case of
termination of the Holder's employment or services for Cause, the Option shall
automatically terminate upon first discovery by Data I/O of any reason for such
termination and the Holder shall have no right to purchase any Shares pursuant
to such Option, unless the Plan Administrator determines otherwise. If a
Holder's employment or services with Data I/O are suspended pending an
investigation of whether the Holder shall be terminated for Cause, all the
Holder's rights under any Option likewise shall be suspended during the period
of investigation.

A transfer of employment or services between or among Data I/O and its
Subsidiaries shall not be considered a termination of employment or services.
The effect of a Company-approved leave of absence or short-term break in service
on the terms and conditions of an Option shall be determined by the Plan
Administrator, in its sole discretion.

8. INCENTIVE STOCK OPTION LIMITATIONS

To the extent required by Section 422 of the Code, Incentive Stock Options
shall be subject to the following additional terms and conditions:

8.1 Dollar Limitation.

To the extent the aggregate Fair Market Value (determined as of the Grant
Date) of Common Stock with respect to which Incentive Stock Options are
exercisable for the first time during any calendar year (under the Plan and all
other stock option plans of Data I/O) exceeds $100,000, such portion in excess
of $100,000 shall be treated as a Nonqualified Stock Option. In the event the
Participant holds two (2) or more such Options that become exercisable for the
first time in the same calendar year, such limitation shall be applied on the
basis of the order in which such Options were granted.

8.2 10% Shareholders.

If a Participant owns more than 10% of the total voting power of all
classes of Data I/O's stock, then the exercise price per share of an Incentive
Stock Option shall not be less than 110% of the Fair Market Value of the Common
Stock on the Grant Date and the Option term shall not exceed five (5) years. The
determination of 10% ownership shall be made in accordance with Section 422 of
the Code.

8.3 Eligible Employees.

Individuals who are not employees of Data I/O or one of its parent
corporations or subsidiary corporations may not be granted Incentive Stock
Options. For purposes of this Section 8.3, "parent corporation" and "subsidiary
corporation" shall have the meanings attributed to those terms for purposes of
Section 422 of the Code.

8.4 Term.

The term of an Incentive Stock Option shall not exceed ten (10) years.

8.5 Exercisability.

To qualify for Incentive Stock Option tax treatment, an Option designated
as an Incentive Stock Option must be exercised within three (3) months after
termination of employment for reasons other than death, except that, in the case
of termination of employment due to total Disability, such Option must be
exercised within one (1) year after such termination. Employment shall not be
deemed to continue beyond the first 90 days of a leave of absence unless the
Participant's reemployment rights are guaranteed by statute or contract.

8.6 Taxation of Incentive Stock Options.

In order to obtain certain tax benefits afforded to Incentive Stock Options
under Section 422 of the Code, the Participant must hold the shares issued upon
the exercise of an Incentive Stock Option for two (2) years after the Grant Date
of the Incentive Stock Option and one (1) year from the date the shares are
transferred to the Participant. A Participant may be subject to the alternative
minimum tax at the time of exercise of an Incentive Stock Option. The
Participant shall give Data I/O prompt notice of any disposition of shares
acquired by the exercise of an Incentive Stock Option prior to the expiration of
such holding periods.

8.7 Promissory Notes.

The amount of any promissory note delivered pursuant to Section 12 in
connection with an Incentive Stock Option shall bear interest at a rate
specified by the Plan Administrator but in no case less than the rate required
to avoid imputation of interest (taking into account any exceptions to the
imputed interest rules) for federal income tax purposes.

8.8 Incorporation of Other Provisions.

With respect to Incentive Stock Options, if this Plan does not contain any
provision required to be included herein under Section 422 of the Code, such
provision shall be deemed to be incorporated herein with the same force and
effect as if such provision had been set out in full herein; provided, however,
that to the extent any Option that is intended to qualify as an Incentive Stock
Option cannot so qualify, the Option, to that extent, shall be deemed to be a
Nonqualified Stock Option for all purposes of this Plan.

9. STOCK APPRECIATION RIGHTS

9.1 Grant of Stock Appreciation Rights.

The Plan Administrator may grant a Stock Appreciation Right separately or
in tandem with a related Option.

9.2 Tandem Stock Appreciation Rights.

A Stock Appreciation Right granted in tandem with a related Option will
give the Holder the right to surrender to Data I/O all or a portion of the
related Option and to receive an appreciation distribution (in shares of Common
Stock or cash or any combination of shares and cash, as the Plan Administrator,
in its sole discretion, shall determine at any time) in an amount equal to the
excess of the Fair Market Value for the date the Stock Appreciation Right is
exercised over the exercise price per share of the right, which shall be the
same as the exercise price of the related Option. A tandem Stock Appreciation
Right will have the same other terms and provisions as the related Option. Upon
and to the extent a tandem Stock Appreciation Right is exercised, the related
Option will terminate.

9.3 Stand-Alone Stock Appreciation Rights.

A Stock Appreciation Right granted separately and not in tandem with an
Option will give the Holder the right to receive an appreciation distribution in
an amount equal to the excess of the Fair Market Value for the date the Stock
Appreciation Right is exercised over the exercise price per share of the right.
A stand-alone Stock Appreciation Right will have such terms as the Plan
Administrator may determine, except that the term of the right, if not otherwise
established by the Plan Administrator, shall be ten (10) years from the Grant
Date.

9.4 Exercise of Stock Appreciation Rights.

Unless otherwise provided by the Plan Administrator in the instrument that
evidences the Stock Appreciation Right, the provisions of Section 7.6 relating
to the termination of a Holder's employment or services shall apply equally, to
the extent applicable, to the Holder of a Stock Appreciation Right.

10. STOCK AWARDS

10.1 Grant of Stock Awards.

The Plan Administrator is authorized to make Awards of Common Stock or of
rights to receive shares of Common Stock to Participants on such terms and
conditions and subject to such restrictions, if any (which may be based on
continuous service with Data I/O or the achievement of performance goals related
to (i) sales, gross margin, operating profits or profits, (ii) growth in sales,
gross margin, operating profits or profits, (iii) return ratios related to
sales, gross margin, operating profits or profits, (iv) cash flow, (v) asset
management (including inventory management), or (vi) total shareholder return,
where such goals may be stated in absolute terms or relative to comparison
companies), as the Plan Administrator shall determine, in its sole discretion,
which terms, conditions and restrictions shall be set forth in the instrument
evidencing the Award. The terms, conditions and restrictions that the Plan
Administrator shall have the power to determine shall include, without
limitation, the manner in which shares subject to Stock Awards are held during
the periods they are subject to restrictions and the circumstances under which
forfeiture of Restricted Stock shall occur by reason of termination of the
Holder's services or upon the occurrence of other events.

10.2 Issuance of Shares.

Upon the satisfaction of any terms, conditions and restrictions prescribed
with respect to a Stock Award, or upon the Holder's release from any terms,
conditions and restrictions of a Stock Award, as determined by the Plan
Administrator, Data I/O shall transfer, as soon as practicable, to the Holder
or, in the case of the Holder's death, to the personal representative of the
Holder's estate or as the appropriate court directs, the appropriate number of
shares of Common Stock covered by the Award. 10.3 Waiver of Restrictions.

Notwithstanding any other provisions of the Plan, the Plan Administrator
may, in its sole discretion, waive the forfeiture period and any other terms,
conditions or restrictions on any Restricted Stock under such circumstances and
subject to such terms and conditions as the Plan Administrator shall deem
appropriate.

11. OTHER STOCK-BASED AWARDS

The Plan Administrator may grant other Awards under the Plan pursuant to
which shares of Common Stock (which may, but need not, be shares of Restricted
Stock pursuant to Section 10) are or may in the future be acquired, or Awards
denominated in stock units, including ones valued using measures other than
market value. Such Other Stock-Based Awards may be granted alone or in addition
to or in tandem with any Award of any type granted under the Plan and must be
consistent with the Plan's purpose.

12. LOANS, INSTALLMENT PAYMENTS AND LOAN GUARANTEES

To assist a Holder (including a Holder who is an officer or director of
Data I/O) in acquiring shares of Common Stock pursuant to an Award granted under
the Plan, the Plan Administrator, in its sole discretion, may authorize, either
at the Grant Date or at any time before the acquisition of Common Stock pursuant
to the Award, (a) the extension of a loan to the Holder by Data I/O, (b) the
payment by the Holder of the purchase price, if any, of the Common Stock in
installments, or (c) the guarantee by Data I/O of a loan obtained by the grantee
from a third party. The terms of any loans, installment payments or loan
guarantees, including the interest rate and terms of and security for repayment,
will be subject to the Plan Administrator's discretion; provided, however, that
repayment of any Company loan to the Holder shall be secured by delivery of a
full-recourse promissory note for the loan amount executed by the Holder,
together with any other form of security determined by the Plan Administrator.
The maximum credit available is the purchase price, if any, of the Common Stock
acquired, plus the maximum federal and state income and employment tax liability
that may be incurred in connection with the acquisition.

13. ASSIGNABILITY

Except as otherwise specified or approved by the Plan Administrator at the
time of grant of an Award or any time prior to its exercise, no Award granted
under the Plan may be assigned, pledged or transferred by the Holder other than
by will or by the laws of descent and distribution, and during the Holder's
lifetime, such Awards may be exercised only by the Holder. Notwithstanding the
foregoing, and to the extent permitted by Section 422 of the Code, the Plan
Administrator, in its sole discretion, may permit such assignment, transfer and
exercisability and may permit a Holder of such Awards to designate a beneficiary
who may exercise the Award or receive compensation under the Award after the
Holder's death; provided, however, that (i) any Award so assigned or transferred
shall be subject to all the same terms and conditions contained in the
instrument evidencing the Award, (ii) the original Holder shall remain subject
to withholding taxes upon exercise, (iii) any subsequent transfer of an Award
shall be prohibited and (iv) the events of termination of employment or
contractual relationship set forth in subsection 7.6 shall continue to apply
with respect to the original transferor-Holder.

14. ADJUSTMENTS

14.1 Adjustment of Shares.

In the event that, at any time or from time to time, a stock dividend,
stock split, spin-off, combination or exchange of shares, recapitalization,
merger, consolidation, distribution to shareholders other than a normal cash
dividend, or other change in Data I/O's corporate or capital structure results
in (a) the outstanding shares, or any securities exchanged therefor or received
in their place, being exchanged for a different number or class of securities of
Data I/O or of any other corporation or (b) new, different or additional
securities of Data I/O or of any other corporation being received by the holders
of shares of Common Stock of Data I/O, then the Plan Administrator, in its sole
discretion, shall make such equitable adjustments as it shall deem appropriate
in the circumstances in (i) the maximum number and class of securities subject
to the Plan as set forth in Section 4.1, (ii) the maximum number and class of
securities that may be made subject to Awards to any individual Participant as
set forth in Section 4.2, and (iii) the number and class of securities that are
subject to any outstanding Award and the per share price of such securities,
without any change in the aggregate price to be paid therefor. The determination
by the Plan Administrator as to the terms of any of the foregoing adjustments
shall be conclusive and binding.

14.2 Dissolution, Liquidation or Change in Control Transactions.

(a) In the event of the proposed dissolution or liquidation of Data I/O,
Data I/O shall notify each Holder at least fifteen (15) days prior to such
proposed action. To the extent not previously exercised, all Awards will
terminate immediately prior to the consummation of such proposed action.

(b) Unless the applicable agreement representing an Option provides
otherwise, or unless the Plan Administrator determines otherwise in its sole and
absolute discretion in connection with any Change in Control, a Qualifying
Option which is not exercisable in full shall become exercisable in connection
with a Change in Control which becomes effective before the Holder's service to
Data I/O terminates as follows:

(i) If the Qualifying Option remains outstanding following the Change in
Control, is assumed by the surviving entity or its parent, or the surviving
entity or its parent substitutes options with substantially the same terms for
such Qualifying Option, the vesting and exercisability of the Qualifying Option
shall be accelerated to the extent of 25% of the Unvested Portion thereof, and
the remaining 75% of the Unvested Portion of such Qualifying Option shall vest
in accordance with the vesting schedule set forth in the applicable Option
agreement.

(ii) If the Qualifying Option remains outstanding following the Change in
Control, is assumed by the surviving entity or its parent, or the surviving
entity or its parent substitutes options with substantially the same terms for
such Qualifying Option and if the Holder thereof is subject to an Involuntary
Termination within 180 days following such Change in Control, then all Options
held by such Holder (or options issued in substitution thereof) shall become
exercisable in full, whether or not the vesting requirements set forth in the
Option agreement have been satisfied, for a period of 90 days commencing on the
effective date of such Holder's Involuntary Termination, or if shorter, the
remaining term of the option.

(iii) If a Qualifying Option does not remain outstanding, and either such
Qualifying Option is not assumed by the surviving entity or its parent, or the
surviving entity or its parent does not substitute options with substantially
the same terms for such Qualifying Option, such Qualifying Option shall become
exercisable in full, whether or not the vesting requirements set forth in the
Option agreement have been satisfied, for a period prior to the effective date
of such Change in Control of a duration specified by the Plan Administrator, and
thereafter the Option shall terminate.

(c) Unless the applicable agreement representing an Award provides
otherwise, or unless the Plan Administrator determines otherwise in its sole and
absolute discretion in connection with any Change in Control, the vesting of
Qualifying Shares shall be accelerated, and Data I/O's repurchase right with
respect to such shares shall lapse, in connection with a Change in Control which
becomes effective before such Holder's service to Data I/O terminates as
follows:

(i) If Qualifying Options were outstanding at the effective time of the
Change in Control and they are partially accelerated pursuant to Subsection
(b)(i) above or if there were no Qualifying Options outstanding at the effective
time of the Change in Control, the vesting of all Qualifying Shares shall be
accelerated to the extent of 25% of the Unvested Portion thereof, and the
remaining 75% of the Unvested Portion of such Qualifying Shares shall vest in
accordance with the vesting schedule set forth in the applicable Award
agreement.

(ii) If the preceding clause (i) applied and if a Holder of Qualifying
Shares is subject to an Involuntary Termination within 180 days following the
same Change in Control, then all Qualifying Shares held by such Holder (or
shares issued in substitution thereof) shall become vested in full, whether or
not the vesting requirements set forth in the applicable Award agreement have
been satisfied.

(iii) If Qualifying Options were outstanding at the effective time of the
Change in Control and they are accelerated in full pursuant to Subsection
(b)(iii) above or otherwise, the vesting of all Qualifying Shares shall be
accelerated in full, and Data I/O's repurchase right with respect to all such
shares shall lapse in full, whether or not the vesting requirements set forth in
the applicable Award agreement have been satisfied.

(d) Notwithstanding Subsections (b) and (c) above, if Data I/O and the
other party to the transaction constituting a Change in Control agree that such
transaction is to be treated as a "pooling of interests" for financial reporting
purposes, and if Data I/O's independent public accountants and such other
party's independent public accountants separately determine in good faith that
the transaction constituting a Change in Control would qualify for treatment as
a "pooling of interests" but for the acceleration of vesting provided for in
Subsections (b) and (c) above, then the acceleration of exercisability or the
lapse of Data I/O's right to repurchase shall not occur to the extent that Data
I/O's independent public accountants and such other party's independent public
accountants separately determine in good faith that such acceleration would
preclude the use of "pooling of interests" accounting for such transaction.

14.3 Further Adjustment of Awards.

Subject to the preceding Section 14.2, the Plan Administrator shall have
the discretion, exercisable at any time before a sale, merger, consolidation,
reorganization, dissolution, liquidation or Change in Control of Data I/O, as
defined by the Plan Administrator, to take such further action as it determines
to be necessary or advisable, and fair and equitable to Participants, with
respect to Awards. Such authorized action may include (but shall not be limited
to) establishing, amending or waiving the type, terms, conditions or duration
of, or restrictions on, Awards so as to provide for earlier, later, extended or
additional time for exercise, payment or settlement or lifting restrictions,
differing methods for calculating payments or settlements, alternate forms and
amounts of payments and settlements and other modifications, and the Plan
Administrator may take such actions with respect to all Participants, to certain
categories of Participants or only to individual Participants. The Plan
Administrator may take such actions before or after granting Awards to which the
action relates and before or after any public announcement with respect to such
sale, merger, consolidation, reorganization, dissolution, liquidation or Change
in Control that is the reason for such action. Without limiting the generality
of the foregoing, if Data I/O is a party to a merger or consolidation,
outstanding Awards shall be subject to the agreement of merger or consolidation.
Such agreement, without the Holder's consent, may provide for:

(a) the continuation of such outstanding Award by Data I/O (if Data I/O is
the surviving corporation);

(b) the assumption of the Plan and some or all outstanding Awards by the
surviving corporation or its parent;

(c) the substitution by the surviving corporation or its parent of Awards
with substantially the same terms for such outstanding Awards; or

(d) the cancellation of such outstanding Awards with or without payment of
any consideration.

14.4 Limitations.

The grant of Awards will in no way affect Data I/O's right to adjust,
reclassify, reorganize or otherwise change its capital or business structure or
to merge, consolidate, dissolve, liquidate or sell or transfer all or any part
of its business or assets.

14.5 Fractional Shares.

In the event of any adjustment in the number of shares covered by any
Option, any fractional shares resulting from such adjustment shall be
disregarded and each such Option shall cover only the number of full shares
resulting from such adjustment.

15. WITHHOLDING

Data I/O may require the Holder to pay to Data I/O in cash the amount of
any withholding taxes that Data I/O is required to withhold with respect to the
grant, exercise, payment or settlement of any Award. Data I/O shall have the
right to withhold from any Award or any shares of Common Stock issuable pursuant
to an Award or from any cash amounts otherwise due or to become due from Data
I/O to the Participant an amount equal to such taxes. Data I/O may also deduct
from any Award any other amounts due from the Participant to Data I/O or a
Subsidiary.

16. AMENDMENT AND TERMINATION OF PLAN

16.1 Amendment of Plan.

The Plan may be amended by the Board in such respects as it shall deem
advisable including, without limitation, such modifications or amendments as are
necessary to maintain compliance with applicable statutes, rules or regulations;
however, to the extent required for compliance with Section 422 of the Code or
any applicable law or regulation, shareholder approval will be required for any
amendment that will increase the aggregate number of shares as to which
Incentive Stock Options may be granted or change the class of persons eligible
to participate. Amendments made to the Plan which would constitute
"modifications" to Incentive Stock Options outstanding on the date of such
Amendments shall not be applicable to such outstanding Incentive Stock Options
but shall have prospective effect only. The Board may condition the
effectiveness of any amendment on the receipt of shareholder approval at such
time and in such manner as the Board may consider necessary for Data I/O to
comply with or to avail Data I/O, the Holders or both of the benefits of any
securities, tax, market listing or other administrative or regulatory
requirement which the Board determines to be desirable. Whenever shareholder
approval is sought, and unless required otherwise by applicable law or exchange
requirements, the proposed action shall require the affirmative vote of holders
of a majority of the shares present, entitled to vote and voting on the matter
without including abstentions or broker non-votes in the denominator.

16.2 Termination Of Plan.

Data I/O's shareholders or the Board may suspend or terminate the Plan at
any time. The Plan will have no fixed expiration date; provided, however, that
no Incentive Stock Options may be granted more than ten (10) years after the
earlier of the Plan's adoption by the Board or approval by the shareholders.

17. GENERAL

17.1 Award Agreements.

Awards granted under the Plan shall be evidenced by a written agreement
which shall contain such terms, conditions, limitations and restrictions as the
Plan Administrator shall deem advisable and which are not inconsistent with the
Plan.

17.2 Continued Employment or Services; Rights In Awards.

None of the Plan, participation in the Plan as a Participant or any action
of the Plan Administrator taken under the Plan shall be construed as giving any
Participant or employee of Data I/O any right to be retained in the employ of
Data I/O or limit Data I/O's right to terminate the employment or services of
the Participant.

17.3 Registration; Certificates For Shares.

Data I/O shall be under no obligation to any Participant to register for
offering or resale or to qualify for exemption under the Securities Act, or to
register or qualify under state securities laws, any shares of Common Stock,
security or interest in a security paid or issued under, or created by, the
Plan, or to continue in effect any such registrations or qualifications if made.
Data I/O may issue certificates for shares with such legends and subject to such
restrictions on transfer and stop-transfer instructions as counsel for Data I/O
deems necessary or desirable for compliance by Data I/O with federal and state
securities laws.

Inability of Data I/O to obtain, from any regulatory body having
jurisdiction, the authority deemed by Data I/O's counsel to be necessary for the
lawful issuance and sale of any shares hereunder or the unavailability of an
exemption from registration for the issuance and sale of any shares hereunder
shall relieve Data I/O of any liability in respect of the nonissuance or sale of
such shares as to which such requisite authority shall not have been obtained.

17.4 No Rights As A Shareholder.

No Option, Stock Appreciation Right or Other Stock-Based Award shall
entitle the Holder to any cash dividend, voting or other right of a shareholder
unless and until the date of issuance under the Plan of the shares that are the
subject of such Award, free of all applicable restrictions.

17.5 Compliance With Laws And Regulations.

In interpreting and applying the provisions of the Plan, any Option granted
as an Incentive Stock Option pursuant to the Plan shall, to the extent permitted
by law, be construed as an "incentive stock option" within the meaning of
Section 422 of the Code.

17.6 No Trust Or Fund.

The Plan is intended to constitute an "unfunded" plan. Nothing contained
herein shall require Data I/O to segregate any monies or other property, or
shares of Common Stock, or to create any trusts, or to make any special deposits
for any immediate or deferred amounts payable to any Participant, and no
Participant shall have any rights that are greater than those of a general
unsecured creditor of Data I/O.

17.7 Severability.

If any provision of the Plan or any Award is determined to be invalid,
illegal or unenforceable in any jurisdiction, or as to any person, or would
disqualify the Plan or any Award under any law deemed applicable by the Plan
Administrator, such provision shall be construed or deemed amended to conform to
applicable laws, or, if it cannot be so construed or deemed amended without, in
the Plan Administrator's determination, materially altering the intent of the
Plan or the Award, such provision shall be stricken as to such jurisdiction,
person or Award, and the remainder of the Plan and any such Award shall remain
in full force and effect.

18. EFFECTIVE DATE

The Plan's effective date is the date on which it is adopted by the Board,
so long as it is approved by Data I/O's shareholders at any time within twelve
(12) months of such adoption.

Original Plan adopted by the Board on February 28, 2000 and approved by
Data I/O's shareholders in May 2000. The Plan was amended and approved by the
Board and Data I/O's shareholders in 2002 to add an additional 200,000 shares of
Common Stock to be reserved for issuance under the Plan.

The audit committee shall be composed of three or more directors, as determined
by the board of directors. Each of the committee members shall meet the

requirements and who shall not serve for more than two years would bring
valuable financial or accounting experience to the committee. In addition, at
least one of the members shall have past employment experience in finance or
accounting, requisite professional certification in accounting, or any other
comparable experience or background which results in the individual's financial

committee members may appoint their own chair by majority vote provided,
however, that a committee member who does not meet the independence requirements
of NASDAQ shall not serve as chair.

Statement of Policy:

The audit committee of the board of directors assists the board in fulfilling
their oversight responsibility to the shareholders, potential shareholders, the
investment community, and others relating to Data I/O's financial statements and
the financial reporting process, the systems of internal accounting and
financial controls, and the annual independent audit of Data I/O's financial
statements. In so doing, it is the responsibility of the committee to maintain
free and open communication among the committee, independent auditors, and
management of Data I/O. In discharging its oversight role, the committee is
empowered to investigate any matter brought to its attention with full access to
all books, records, facilities, and personnel of Data I/O and the power to
retain outside counsel or other experts for this purpose. Data I/O shall provide
for appropriate funding, as determined by the committee, for payment of
compensation to the independent auditor for the purpose of rendering or issuing
an audit report and to any advisors employed by the committee.

Responsibilities:

1. Appoint, oversee, evaluate and approve compensation for Data I/O's
independent auditor and, if so determined by the audit committee, replace the
independent auditor. Establish policies and procedures for the review and
pre-approval by the committee of all auditing services and permissible non-audit
services (including the fees and terms thereof) to be performed by the
independent auditor.

2. Ensure the receipt of, and evaluate, the written disclosures and the letter
that the independent auditor submits to the audit committee regarding the
auditor's independence in accordance with Independence Standards Board Standard
No. 1. Discuss such reports with the auditor and recommend that the board of
directors take appropriate action to address issues raised by such evaluation.

3. Discuss with the independent auditor the matters required to be discussed by
SAS-61, as it may be modified or supplemented.

4. Instruct management, the independent auditor and any internal auditor that
the committee expects to be informed if there are any subjects that require
special attention or if they perceive any significant weaknesses in Data I/O's
information and reporting systems.

5. Meet with management and the independent auditor to discuss the annual
financial statements and the report of the independent auditor thereon, and to
discuss significant issues encountered in the course of the audit work,
including restrictions on the scope of activities, access to required
information and the adequacy of internal financial controls.

6. Review the management letter delivered by the independent auditor in
connection with the audit.

7. Meet quarterly with management and the independent auditor to discuss the
quarterly financial statements prior to the filing of the Form 10Q; provided
that this responsibility may be delegated to the chairman of the audit
committee.

8. Meet at least once each year in separate executive sessions with management
and the independent auditor to discuss matters that any of them or the committee
believes could significantly affect the financial statements and should be
discussed privately.

9. Have such meetings with management and the independent auditor as the
committee deems appropriate to discuss significant financial risk exposures
facing Data I/O and management's plans for monitoring and controlling such
exposures.

10. Review significant changes to Data I/O's accounting principles and practices
proposed by the independent auditor or management.

11. Provide minutes of audit committee meetings to the board of directors, and
report to the board of directors on any significant matters arising from the
committee's work.

12. At least annually, review and reassess this charter and, if appropriate,
recommend proposed changes to the board of directors.

13. Prepare the report required by the rules of the Securities and Exchange
Commission to be included in Data I/O's annual proxy statement.

14. Review and approve all related-party or conflict-of-interest transactions
(as defined by the relevant NASDAQ listing requirements) involving other members
of the board of directors or Data I/O's senior management.

15. Establish procedures for the receipts, retention and treatment of complaints
received by Data I/O regarding accounting, internal accounting controls, or
auditing matters, and the confidential, anonymous submission by employees of
concerns regarding questionable accounting or auditing matters.

16. Establish policies for the hiring of employees and former employees of the
independent auditor.

17. In the performance of its responsibilities, the audit committee is the
representative of the shareholders. However, it is not the responsibility of the
audit committee to plan or conduct audits, or to determine whether Data I/O's
financial statements are complete and accurate or in accordance with generally
accepted accounting principles.
