(the "Record Date") are entitled to notice of and to vote at the Annual Meeting.
This  Proxy  Statement  and a copy  of  the  Company's  2002  Annual  Report  to
Shareholders are being mailed to shareholders on or about March 31, 2003.

A proxy card is enclosed for your use. You are  requested on behalf of the Board

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

appropriate  box under  Item No. 2 on your  proxy  card.  You may (a) vote "FOR"

                     VOTING SECURITIES AND PRINCIPAL HOLDERS

The only outstanding voting securities of the Company are shares of common stock
(the "Common  Stock").  As of the Record Date,  there were  7,883,188  shares 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
the Company's charter  documents,  if a quorum is present,  the six 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 1982
Plan and to ratify the continued  appointment of Grant Thornton as the Company'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 the Company.

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 21,
2003, was $1.15 per share.

The  following  table sets forth  information  with respect to all  shareholders
known by the Company to be the  beneficial  owners of more than five  percent of
its outstanding  Common Stock as of March 21, 2003. Except as noted below,  each
person or entity  has sole  voting and  investment  powers  with  respect to the
shares shown.

Nominations  and Proposals  for the 2003 Annual  Meeting of  Shareholders".  The
Nominating Committee did not meet during fiscal 2002.

During the fiscal year ended December 31, 2002,  there were five meetings of the
Board of  Directors.  Each of the  incumbent  directors who were on the Board of
Directors during fiscal 2002 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.

Compensation Committee Interlocks and Insider Participation

For the fiscal year ended December 31, 2002, 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 the Company 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  (Fred  Hume) do not  receive  additional  compensation  for
serving  on the  Board of  Directors.  Non-employee  directors  received  a cash
retainer  for fiscal year 2002 of $3,750 for each quarter of service plus $1,000
for  each  full  Board  of  Directors   meeting   attended  and  $500  for  each
teleconference  Board  of  Directors  meeting  attended.   Additional  quarterly
compensation was paid to the  non-employee  directors for serving as Chairman of
the Board of Directors or as a committee chair; $2,500 for Chairman of the Board
of Directors  and $750 for the Audit,  Compensation,  and  Nominating  Committee
chairs. In addition,  each non-employee  Board of Directors member as of May 15,
2002, was granted 7,500 stock options.  The stock options were granted under the
provisions and terms of the Company's 2000 Stock  Incentive  Compensation  Plan.
The  Company  also  reimburses  non-employee  directors  for  actual  travel and
out-of-pocket expenses incurred in connection with service to the Company.

The  following  table shows  compensation  paid by the  Company to  non-employee
directors during fiscal year 2002.

(1) Stock Options were granted to the directors in May 2002 at an exercise price
of $1.251 per share.  The options granted vest quarterly over three years
and expire at the end of six years.

Section 16(a) Beneficial Ownership Reporting Compliance

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

To the Company's knowledge, based solely on its review of copies of such reports
furnished to the Company 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 2002.



                             AUDITOR INDEPENDENCE

Report of the Audit Committee

The Audit Committee oversees the Company'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. 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 the Company'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 the Company including the matters in
the written  disclosures and the letter required by the  Independence  Standards
Board and considered the  compatibility of nonaudit  services with the auditors'
independence.

The  Committee  discusses  with the Company'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 the  Company's  internal
controls,  and the overall  quality of the Company's  financial  reporting.  The
Committee held five meetings during fiscal year 2002.

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 the Company's Annual
Report  (Form  10-K) for the year ended  December  31,  2002 for filing with the
Securities  and Exchange  Commission.  The Committee has selected Grant Thornton
LLP as the Company's auditors for the current year.

Audit Fees:  The aggregate  fees billed by Grant  Thornton LLP for  professional
services  rendered for the audit of the Company's  financial  statements for the
fiscal year ended December 31, 2002, and for review of the financial  statements
included in each of the Company's Form 10-Q,  including  audit related fees were
approximately $135,300.00.

Financial  Information  Systems Designs and Implementation  Fees: Grant Thornton
LLP did not bill for any professional services for financial information systems
design or  implementation  as described in Paragraph  (c)(4)(ii) or Rule 2-01 of
Regulation S-X for the fiscal year ended December 31, 2002.

All Other Fees:  Aggregate fees billed for all other services  rendered by Grant
Thornton LLP,  other than the services  covered in the two previous  paragraphs,
for the fiscal year ended December 31, 2002 were approximately $4,200.00.

The Committee has considered whether the services provided by Grant Thornton LLP
are compatible with  maintaining the  independence of Grant Thornton LLP and has
concluded that the  independence  of Grant Thornton LLP is maintained and is not
compromised by the services provided.

                             EXECUTIVE COMPENSATION

Report of Compensation Committee 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 the Company.

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 the Company'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 the Company,  located primarily in the United States. This group was selected
as it is believed to be  representative  of the companies with which the Company
competes for key employees.

The Committee's objective is to maintain a salary structure which, when combined
with annual incentive  compensation,  provides the Company'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, management has continued to freeze base salaries at the 2001
level and deferred  consideration  of normal annual  adjustments  as part of the
Company'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  guidelines")  for  executives  for a given  year are  established  by the
Committee  early in the year. The 2002 MICP  guidelines  for executive  officers
ranged from 25% to 40% of base salary.

The actual MICP payout to an executive officer, in relation to his guideline for
2002 was a function  of the  Company's  net  income  compared  to  predetermined
targets.  The Committee believes that these targets and metrics were measures of
key  activities  for the Company  during 2002 which will  affect  near-term  and
long-term  shareholder value.  Guideline MICP or incentive payouts is to be paid
to an  executive  officer if the  Company  and the  officer  achieves a combined
result versus targets and objectives of 100%. A greater or lesser  percentage of
guideline  is to be paid if a  combined  result of  greater or less than 100% is
achieved.

The MICP for 2002 provided  that MICP payouts would be based on the  achievement
of a certain level of the combined  objectives  described  above. In some cases,
not all officers  would receive an MICP payout.  The maximum payout to executive
officers  under MICP cannot exceed 150% of guideline.  For 2002,  the net income
targets were not  achieved.  No executive  officers  received an MICP payout for
2002. See "Summary Annual Compensation Table."

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 the Company'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 2002 were based on these criteria.

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,  the  Company's
outstanding options represented approximately 14.2% of outstanding shares, which
the  Company  believes  is slightly  below the  average  within the  electronics
industry.

Historically,  all options  granted by the  Company  have been  granted  with an
exercise  price equal to the fair market value of the Company's  Common Stock on
the date of grant and, accordingly,  will only have value if the Company's stock
price increases. All officer options granted during 2002 become exercisable at a
rate of 6.25% per  quarter.  50,000  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
acceleration provisions provided for 25,000 of the options to vest at the end of
2000 if predetermined profit and revenue targets were achieved. The targets were
not  achieved for 2000;  therefore,  no options  vested  under the  acceleration
provisions.  If at the end of 2001,  a  predetermined  earnings  per share (EPS)
target was achieved,  25,000 of the options would vest at that time. The targets
were not achieved for 2001; therefore,  no options vested under the acceleration
provisions.  If any  remaining  options are unvested at the end of 2001,  25,000
vest if the revenue  and profit are 120% or more of the April 26, 2000  forecast
for 2000. If any remaining  shares are unvested at the end of 2002,  25,000 vest
if EPS is equal to or more than the  predetermined  target for 2002. The targets
were not achieved for 2002; therefore,  no options vested under the acceleration
provisions. If any remaining shares are unvested at the end of 2002, 25,000 vest
if the revenue and profit are 144% or more of the April 26,  2000  forecast  for
2000.  If any remaining  shares are unvested at the end of 2003,  25,000 vest if
EPS is equal to or more than the predetermined target for 2003. If any remaining
shares are  unvested  at the end of 2003,  25,000 vest if the revenue and profit
are 173% or more of the April 26, 2000 forecast for 2000.

Options granted during 2000 under the 2000 Plan become  exercisable at a rate of
6.25% per quarter.  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.

In January 2000, the Board of Directors  approved a  modification  to Mr. Hume's
outstanding 1999 granted options providing that if the Company performed at 125%
of a predetermined profit target in 2000, 50% of Mr. Hume's outstanding unvested
options  would vest at December  31, 2000 with the  remaining  unvested  options
vesting  as  originally  scheduled.  The  targets  were not  achieved  for 2001;
therefore, no options vested under these acceleration provisions.

All grants are subject to  acceleration  of vesting in  connection  with certain
events leading to a change in control of the Company 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 the Company. See "Change
in Control Arrangements."

For  additional  information  concerning  the number of new  options  granted in
fiscal 2002 to the Chief  Executive  Officer and other executive  officers,  see
"Option/SAR Grants in the Last Fiscal 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 the Company, 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 the Company'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  the  Company'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, Company 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.  In light of the current economic situation,
management  has continued to freeze base salaries at the 2001 level and deferred
consideration of normal annual  adjustments as part of the Company's  short-term
cost control efforts.

The  Compensation  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.

The  Company has entered  into  agreements  (the  "Severance  Agreements")  with
certain executive  officers whereby such individuals will 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 the Company.  See "Change in Control  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 fiscal year unless such  compensation
meets  certain  requirements.  The  Committee  is aware of this  limitation  and
believes that no compensation paid by the Company during 2002 will exceed the $1
million  limitation,  except possibly a portion of the sums payable  pursuant to
the Severance Agreements, if paid.

(1)  An equal  number of SARs are  granted  in tandem  with  options  granted to
     executive  officers.  SARs are  exercisable  only  upon the  occurrence  of
     certain  events  leading  to a change in the  control of the  Company.  See
     "Change in Control and Severance Arrangements."
(2)  Under  the  terms of the 1986  Plan and the  2000  Plan,  the  Compensation
     Committee retains  discretion,  subject to plan limits, to modify the terms
     of and reprice outstanding options.
(3)  The exercise price may be paid by delivery of already owned shares, subject
     to certain conditions.
(4)  Potential  realizable  value is based on an assumption that the stock price
     of the  Common  Stock  appreciates  at the annual  rate  shown  (compounded
     annually)  from the date of grant until the end of the option  term.  These
     numbers are  calculated  based on SEC  requirements  and do not reflect the
     Company's estimate of future stock price growth.
(5)  All new options granted in 2002 become exercisable  commencing three months
     after grant date,  with 6.25% of the shares  becoming  exercisable  at that
     time and an additional  6.25% of the shares  becoming  exercisable  on each
     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 the Company.  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 terminated.

(1)  Market value of underlying  securities at exercise date, minus the exercise
     or base price of in-the-money  options/SARs.
(2)  Future  exercisability is subject to vesting and the optionee  remaining in
     the  employment  of the Company.  In  addition,  all options are granted in
     tandem with an equal  number of SARs.  SARs are only  exercisable  upon the
     occurrence  of certain  events  leading  to a change in the  control of the
     Company. See "Change in Control and Severance Arrangements."
(3)  This value is  calculated  by  multiplying  the market  value of the Common
     Stock at  December  31,  2002,  which was  $0.91 as  quoted  on the  NASDAQ
     National  Market,  less  the  exercise  or  base  price  by the  number  of
     in-the-money  options/SARs held. If the number is zero, the aggregate value
     of the options are out-of-the-money.

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 the Company'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 the Company's assets. With any of the foregoing transactions, the Company
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, the Company  adopted a Stock  Appreciation  Rights  ("SARs") Plan which
allows the Board of Directors to grant to each  director,  executive  officer or
holder of 10% or more of the stock of the Company a SAR with  respect to certain
options  granted to these  parties.  A SAR has been  granted in tandem with each
option  granted to an officer of the Company.  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 the Company (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 the  Company's  Common  Stock  into
securities of a third party,  or cash, or property,  or a combination  of any of
the foregoing.

The Company 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. The respective  agreements with Messrs. Hatlen
and Hume provide for a lump sum payment to the officer upon  termination  of the
officer's  employment  by the Company  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 the  Company.  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 fiscal
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 officer's  most recent five taxable
years.

In connection with execution of the Severance  Agreements,  the Company required
Messrs. Hatlen and Hume to sign a confidentiality and non-competition agreement,
which includes,  among other things,  a restriction  against  competing with the
Company or soliciting employees from the Company 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 the  Company  because  the  Severance
Agreements will enable the executive officers to continue to focus on activities
providing for the maximum  long-term value to the Company's  shareholders,  even
when faced with the possible  change of control of the Company or termination of
their  employment.  In addition,  each of the  executive  officers  named in the
Summary  Compensation  Table have signed the Company's  form of offer letter and
have  entered  into  a  Confidentiality  and  Intellectual  Property  Assignment
Agreement  (the  "Confidentiality  Agreement")  with the  Company.  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 the Company for one year  following  termination  of their
employment.

           PROPOSAL 2: AMENDMENT TO 1982 EMPLOYEE STOCK PURCHASE PLAN

At the annual meeting,  the shareholders of the Company will be asked to approve
an amendment to the Company's 1982 Employee Stock Purchase Plan, as amended (the
"Purchase  Plan"),  which,  if approved,  will  increase the number of shares of
Common Stock available for purchase under the Purchase Plan by 300,000 shares to
an aggregate  of 2,150,000  shares.  The Board of  Directors  believes  that the
Purchase Plan has contributed to  strengthening  the incentive of  participating
employees  to achieve the  objectives  of the Company  and its  shareholders  by
encouraging  employees to acquire a greater proprietary interest in the Company.
Since its  inception,  a total of  1,796,443  shares of Common  Stock  have been
purchased  under  the  Purchase  Plan,  and a total of  53,557  shares  remained
available for purchase thereunder as of the Record Date.

The proposed  increase in the number of shares  available for purchase under the
Purchase  Plan will simply  enable the Company to continue the Purchase Plan and
is not required or intended to supply or "cover"  outstanding awards to Purchase
Plan participants. As such, no "New Plan Benefits" have been granted to date and
future awards under the Purchase 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 2003  Annual  Meeting  and
entitled to vote on the proposal is required  for  approval of the  amendment to
the Purchase Plan. THE BOARD OF DIRECTORS  RECOMMENDS THAT SHAREHOLDERS VOTE FOR
APPROVAL OF THE  PROPOSED  AMENDMENT  TO THE PURCHASE  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 Purchase Plan.

Description of the 1982 Stock Purchase Plan

The following  description  of the Purchase 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 Purchase Plan,  which is intended to qualify
under Section 423 of the Internal Revenue Code ("the Code"),  was adopted by the
Board of Directors  in February  1982 and  approved by its  shareholders  in May
1982. The Purchase Plan was amended by the Company's shareholders in May 1991 to
increase  the  number of shares of Common  Stock  available  for  purchase  from
500,000 to 750,000,  was amended by the  Company's  shareholders  in May 1993 to
increase the number of shares  available for purchase from 750,000 to 1,150,000,
was amended by the Company's  shareholders in May 1996 to increase the number of
shares available for purchase from 1,150,000 to 1,550,000, and was again amended
in May 2001 to  increase  the  number  of shares  available  for  purchase  from
1,550,000 to 1,850,000.

General. Employees are eligible to participate, with certain exceptions, if they
are employed by the Company or its  subsidiaries for at least 20 hours per week.
As of the Record Date the number of eligible participants was approximately 120.
Employees who own five percent or more of the voting stock of the Company or its
subsidiaries  are  not  eligible  to  participate  in the  Purchase  Plan.  Each
participant  agrees to a payroll  deduction for each semi-annual  six-month plan
period (a "Payment  Period"),  which periods commence on August 1 and February 1
of each year and  terminate on January 31 and July 31,  respectively.  Aggregate
deductions may not be greater than 10% of an employee's  base pay in any Payment
Period.  No employee shall be granted  options which permit his or her rights to
purchase  Common Stock under the Purchase  Plan and any other option plan of the
Company or any subsidiary corporations to accrue at a rate which exceeds $25,000
in fair  market  value of such  stock  (determined  at date of  grant)  for each
calendar year in which such options are at any time outstanding.

Participants  in the plan receive an option to  purchase,  generally on the last
day of a Payment Period, at a price determined as described below (the "Purchase
Price"),  the number of full  shares of Common  Stock of the  Company  which the
participant's  accumulated  payroll  deductions  on the last day of such Payment
Period will purchase at the Purchase Price.  The Purchase Price for each Payment
Period is the lesser of 85% of the fair market  value of the Common Stock on the
first  business day of the Payment Period or 85% of the fair market value of the
Common  Stock on the last  business day of the Payment  Period.  The Company has
determined the "fair market value" on any given day to be the last sale price of
the Common Stock as reported by NASDAQ  National Market System or, if the Common
Stock is not quoted in the National Market System,  the mean between the closing
bid and asked  prices  of the  Common  Stock as quoted by NASDAQ on such day.  A
participant may withdraw from  participation  in the Purchase Plan by delivering
written notice at any time prior to the last business day of any Payment Period,
in which  event the  Company  will  promptly  refund the  entire  balance of the
participant's account. Termination of employment cancels the participant's right
to continue in the  Purchase  Plan and results in a refund of the  participant's
account.   Purchase  rights  granted  under  the  Plan  are  not  assignable  or
transferable.  The Board of Directors may at any time amend, modify or terminate
the  Purchase  Plan with the  exception  that,  without  prior  approval  of the
shareholders of the Company,  the Board of Directors may not increase the number
of shares which may be issued pursuant to the Purchase Plan.

Federal  Income Tax  Consequences.  This  description  of the federal income tax
consequences of participation in the Purchase Plan is intended merely to provide
basic  information  with  respect to the tax  treatment  applied to the Purchase
Plan.  Although the Company believes the following  statements are correct based
on  existing  provisions  of the  Code  and its  legislative  history,  Treasury
regulations    promulgated    thereunder   and    administrative   or   judicial
interpretations   thereof,   the  Company   cannot   assure  that   legislative,
administrative or judicial changes or interpretations will not occur which would
modify  such  statements.   In  connection  with  their  particular  income  tax
liability,  participants  in the Purchase Plan are urged to obtain  professional
advice regarding the applicability of federal, state and local tax laws.

Under  Section  423(a)  of the  Code,  the  transfer  of a share  of  stock to a
participant pursuant to the Purchase Plan is entitled to the benefits of Section
421(a) of the Code.  Under that Section,  a participant  will not be required to
recognize  income at the time the option is granted or at the time the option is
exercised.  As the option  price under the  Purchase  Plan is less than the fair
market  value of the  stock on the date of  grant,  Section  423(c)  of the Code
requires,  in general,  that,  provided the holding periods  described below are
met, when the shares of stock received pursuant to the Purchase Plan are sold or
otherwise  disposed of in a taxable  transaction the participant  will recognize
compensation  income (taxed as ordinary income) in an amount equal to the lesser
of either the excess of the fair market value of the Common Stock at the time of
such  disposition  over the amount paid for the stock or 15% of the stock's fair
market  value  at the date the  option  was  granted.  The  Company  will not be
entitled to any expense  deduction with respect to the Purchase Plan,  except in
connection with a disqualifying  disposition as discussed  below. Any additional
gain or loss resulting from the disposition,  measured by the difference between
the  amount  paid for the  shares  and the  amount  realized  (less  the  amount
recognized as a compensation  income described above), will be recognized to the
participant as long-term capital gain or loss. No portion of the amount received
pursuant to such a disposition will be subject to withholding for federal income
taxes or be subject to FICA or FUTA taxes.

Under  current  law,  net capital  gains are subject to tax at a maximum rate of
20%,  whereas ordinary income will generally be taxed at up to a maximum rate of
38.6%.  The  deductibility  of capital  losses is limited to an amount  equal to
capital gains for the tax year, plus $3,000 ($1,500 for married taxpayers filing
separate returns).

In order for a participant  to receive the  favorable tax treatment  provided by
Section 421(a) of the Code, Section 423(a) requires that the participant make no
disposition  of the shares within two years from the date the option was granted
nor within one year from the date such option was  exercised and the shares were
transferred  to him or her. In  addition,  the  participant  must,  with certain
exceptions  with  respect  to  death  or  disability,  be  an  employee  of  the
corporation  granting  the  option  (or  of  a  parent  or  subsidiary  of  such
corporation, as defined in Section 424(e) and (f) of the Code, or a corporation,
or parent or subsidiary thereof, issuing or assuming the option in a transaction
to which Section 424(a) applies) at all times within the period beginning on the
date of the grant of the option and ending on a date within three months  before
the date of the exercise.

If a  participant  disposes of the stock  before the  expiration  of the holding
period  requirements set forth above, the participant will realize,  at the time
of the  disposition,  ordinary income to the extent the fair market value of the
stock on the date the shares were  purchased  exceeds the  purchase  price.  The
amount of  ordinary  income  recognized  on such a  disposition  is added to the
participant's basis in the shares. The difference between the amount realized on
such a disposition and the participant's basis in the shares shall be treated as
a capital gain or loss.  Income recognized as a result of such a disposition may
be subject to the income tax withholding requirements of the Code as well as the
FUTA and FICA taxes.  The  participant  is required to reimburse the Company for
all withholding taxes (e.g. Federal income tax and FICA) the Company is required
to pay on behalf of the participant. At the time of the disposition, the Company
will be allowed a corresponding  business expense deduction under Section 162 of
the Code to the  extent of the  amount  of the  participant's  ordinary  income,
provided  such  amount,  when  added  to  any  other  compensation  paid  to the
participant,  is reasonable.  The Purchase Plan is not generally  subject to the
provisions of the Employee  Retirement  Income Security Act of 1974, as amended,
and is not qualified under Section 401 of the Code.

        PROPOSAL 3: RATIFICTION 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 the Company's independent auditors
for calendar year 2003. Grant Thornton LLP examined the  consolidated  financial
statements of the Company for the year ended December 31, 2002.  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.

The Company's previous independent auditors,  Ernst & Young, LLP, were dismissed
by the Board of Directors on November 14, 2001. The Company filed with the SEC a
Form  8-K  and  Form  8-K/A  on  November   21,  2001  and  November  28,  2001,
respectively,   which  announced  that  the  Board  of  Directors,  based  on  a
recommendation from the Audit Committee, approved an action on November 14, 2001
to no longer engage Ernst & Young,  LLP as its independent  auditors.  The Audit
Committee and the Board of Directors  approved  another  independent  accounting
firm,  Grant  Thornton  LLP, as the Company's new  independent  auditors.  Grant
Thornton LLP accepted this appointment on November 27, 2001.

The reports of Ernst & Young, LLP on the Company's financial  statements for the
past two  fiscal  years did not  contain an adverse  opinion  or  disclaimer  of
opinion and were not qualified or modified as to  uncertainty,  audit scope,  or
accounting  principles,  except  that the  Independent  Auditor's  Report on the
consolidated  financial  statements  of the  Company  for the fiscal  year ended
December 28, 2000  contained an  explanatory  paragraph  regarding the Company's
change in its method of accounting for revenue recognition.

In connection with the audits of the Company's financial  statements for each of
the two fiscal years ended  December 28, 2000 and December 30, 1999,  and in the
subsequent  interim period,  there were no disagreements with Ernst & Young, LLP
on any  matters of  accounting  principles  or  practices,  financial  statement
disclosure,  or  auditing  scope and  procedure  which,  if not  resolved to the
satisfaction of Ernst & Young,  LLP would have caused Ernst & Young, LLP to make
reference to the matter in their report.

                                 OTHER BUSINESS

As of the date of this Proxy  Statement,  the  Company 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
                       2004 ANNUAL MEETING OF SHAREHOLDERS

The Company'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 the  Company  90 days  prior to the  date  one  year  from the date
immediately  preceding the Annual Meeting of  Shareholders  or, 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 the Company 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 the  Company'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 the Company  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  Securities  and  Exchange  Commission;  and (v) with
respect to the  nominations,  the consent of each nominee to serve as a director
of the Company if elected.

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

Securities and Exchange  Commission  (the "SEC") rules  establish a deadline for
submission of shareholder  proposals that are not intended to be included in the
Company's   proxy   statement   with  respect  to   discretionary   voting  (the
"Discretionary  Vote Deadline").  The  Discretionary  Vote Deadline for the 2004
Annual  Meeting is February 19, 2004.  If a  shareholder  gives notice of such a
proposal after the Discretionary Vote Deadline, the Company'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 2004  Annual
Meeting.

Shareholders  who  intend to have a proposal  considered  for  inclusion  in the
Company's  proxy  materials  for  presentation  at the 2004 Annual  Meeting must
submit the proposal to the Company no later than December 2, 2003.  Shareholders
who intend to present a proposal at the 2004 Annual Meeting without inclusion of
such proposal in the Company's proxy materials are required to provide notice of
such  proposal  to the  Company no later than  February  19,  2004.  The Company
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 the Company 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 the Company,  none of whom will receive
any additional  compensation  for their services.  In addition,  the Company 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. The Company 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 the
Company.

                              DATA I/O CORPORATION
                        1982 EMPLOYEE STOCK PURCHASE PLAN
                      AMENDED AND RESTATED FEBRUARY 8, 2001

     1.1      Purpose

     This 1982  Employee  Stock  Purchase  Plan (the  "Plan") is  intended as an
incentive and to encourage stock ownership by all eligible employees of Data I/O
Corporation  (the  "Company") and  participating  subsidiaries  so that they may
share  in  the  fortunes  of  the  Company  by  acquiring  or  increasing  their
proprietary  interest in the Company. The Plan is designed to encourage eligible
employees  to remain in the employ of the Company.  It is intended  that options
issued  pursuant to this Plan shall  constitute  options  issued  pursuant to an
"employee  stock  purchase  plan"  within the meaning of Section 423 of the 1986
Internal Revenue Code as amended (the "Code").

     1.2      Eligible Employees

     All regular, full-time employees of the Company or any of its participating
subsidiaries  shall be eligible to receive  options  under this Plan to purchase
the Company's common stock, no par value (the "Common Stock") (except  employees
in countries whose laws make  participating  impractical).  For purposes of this
Plan, the term employee shall include all employees of the Company or any of its
participating  subsidiaries  other than persons  whose  customary  employment is
twenty  (20)  hours or less per week or not more than five (5)  months per year.
Persons who are employees on the August 1 next following the date that this Plan
is approved by the stockholders of the Company shall receive their options as of
such August 1. Persons who become  eligible to participate in the Plan after the
date on which the initial options are granted hereunder shall be granted options
on the next date on which options are granted to all eligible  employees.  In no
event may an employee  participate  in this Plan if such  employee,  immediately
after the option is granted,  owns stock possessing five percent (5%) or more of
the total combined  voting power or value of all classes of stock of the Company
or of its parent  corporation  or subsidiary  corporation,  as the terms "parent
corporation" and "subsidiary corporation" are defined in Section 425 (e) and (f)
of the Code. For purposes of determining  stock  ownership under this paragraph,
the rules of Section 425(d) of the Code shall apply and stock which the employee
may purchase  under  outstanding  options shall be treated as stock owned by the
employee.

     1.3      Stock Subject to the Plan

     The  stock  subject  to the  options  shall  be  shares  of  the  Company's
authorized but unissued Common Stock or shares of Common Stock reacquired by the
Company  including shares purchased in the open market.  The aggregate number of
shares  which may be issued  pursuant to the Plan is one million  eight  hundred
fifty thousand  (1,850,000),  subject to increase or decrease by reason of stock
split-ups,  reclassifications,  stock  dividends,  changes  in par value and the
like.

     1.4      Payment Periods and Stock Options

     The period during which payroll  deductions will accumulate  under the Plan
shall be six (6) months (the  "Payment  Period") and there shall be two (2) such
Payment  Periods in each calendar year,  commencing  August 1 and February 1 and
terminating on January 31 and July 31 of each year,  respectively.  Each Payment
Period includes only regular pay days falling within it.

     On the first business day of each Payment Period, the Company will grant to
each  eligible  employee  who is then a  participant  in the Plan an  option  to
purchase on the last day of such Payment Period at the option price  hereinafter
provided such number of full shares of the Common Stock of the Company, reserved
for the purpose of the Plan, as his or her accumulated payroll deductions on the
last day of such Payment Period will pay for at such option price;  provided and
on condition  that such employee  remains  eligible to  participate  in the Plan
throughout such Payment Period; and provided further, that the maximum number of
shares  granted to any eligible  employee  hereunder in any Payment Period shall
not  exceed  two (2) times the  number  of full  shares of Common  Stock as such
employee's  accumulated  payroll  deductions  would pay for on the exercise date
assuming an exercise price equal to eighty-five percent (85%) of the fair market
value of the Company's Common Stock on the first day of such Payment Period. The
option  price for each  Payment  Period  shall be the lesser of (i) eighty  five
percent  (85%) of the fair market  value of the  Company's  Common  Stock on the
first business day of the Payment  Period;  or (ii) eighty five percent (85%) of
the fair market value of the Company's  Common Stock on the last business day of
the Payment  Period,  in either case  rounded up to avoid  fractions  other than
1/32,  1/16,  1/8, 1/4, 1/2 and 3/4 (the  "Option  Price").  In the  event of an
increase or decrease in the number of outstanding  shares of Common Stock of the
Company through stock split-ups, reclassifications,  stock dividends, changes in
par value and the like, an appropriate adjustment shall be made in the number of
shares  and  Option  Price per share  provided  for under the Plan,  either by a
proportionate  increase in the number of shares and a proportionate  decrease in
the Option  Price per share,  or by a  proportionate  decrease  in the number of
shares and a  proportionate  increase in the Option  Price per share,  as may be
required to enable an eligible employee who is then a participant in the Plan as
to whom an  option  is  exercised  on the last day of any then  current  Payment
Period  to  acquire  such  number  of full  shares  as his  accumulated  payroll
deductions on such date will pay for at the adjusted Option Price.

     For  purposes  of this Plan the term "fair  market  value" on any given day
means: (i) if the Common Stock is listed on a national securities exchange,  the
average of the high and low prices of the  Common  Stock of the  Company on such
exchange or such other  national  securities  exchange as shall be designated by
the  Board  of  Directors;  or  (ii)  if  the  Common  Stock  is  traded  in the
over-the-counter  securities  market, the last sale price of the Common Stock as
quoted by NASDAQ National Market System or, if the Common Stock is not quoted in
the National Market System, the mean between the closing bid and asked prices of
the Common Stock as quoted by NASDAQ.

     For  purposes of this Plan the term  "business  day" as used herein means a
day on which there is trading on any  national  securities  exchange as shall be
designated by the Board of Directors pursuant to the preceding paragraph.

     No employee  shall be granted an option which  permits his or her rights to
purchase Common Stock under the Plan and any similar plans of the Company or any
parent or subsidiary  corporations to accrue at a rate which exceeds twenty five
thousand dollars ($25,000) of fair market value of such stock (determined at the
time such  option is  granted)  for each  calendar  year  which  such  option is
outstanding at any time. The purpose of the limitation in the preceding sentence
is to comply with Section 423(b)(8) of the Code.

     1.5      Exercise of Option

     Each eligible employee who continues to be a participant in the Plan on the
last business day of a Payment  Period shall be deemed to have  exercised his or
her option on such date and shall be deemed to have  purchased  from the Company
such number of full shares of Common Stock  reserved for the purpose of the Plan
as his or her accumulated  payroll  deductions on such date will pay for at such
Option Price.  If a participant is not an employee on the last business day of a
Payment Period,  such  participant  shall not be entitled to exercise his or her
option.

     1.6      Unused Payroll Deductions

     Only full shares of Common Stock may be purchased. Any balance remaining in
an employee's account after a purchase will be reported to the employee and will
be carried forward to the next Payment Period.

     1.7      Authorization for Entering Plan

     An employee may enter the Plan by filling out,  signing and  delivering  to
the Corporate Secretary's office an authorization (the "Authorization"):

     (a) specifying the exact payroll deduction;

     (b) authorizing the purchase of stock in each Payment Period  in accordance
with the terms of the Plan; and

     (c) specifying the exact name in  which stock  purchased is to be issued as
provided under 1.11 hereof.

     Such Authorization must be received by the Corporate  Secretary's office at
least ten (10) days before the beginning  date of such next  succeeding  Payment
Period.

     Unless an employee  files a new  Authorization  or withdraws from the Plan,
his deductions and purchases  under the  Authorization  on file will continue so
long as the Plan remains in effect.

     All payroll  deductions  made for an  employee  shall be  deposited  in the
Company's general corporate account and shall not bear interest. An employee may
not make any  separate  cash payment into such account and may reduce the amount
of the deduction  once during the Payment  Period (see Section 1.9). The Company
will maintain complete records showing the amount of payroll  deductions of each
employee.

     1.8      Maximum Amount of Payroll Deductions

     An employee may authorize payroll  deductions in any whole dollar amount up
to but not more than ten percent (10%) of his or her regular base pay, provided,
however,  that the minimum  deduction in respect of any payroll  period shall be
five dollars ($5.00) (or such lesser amount as the Committee shall establish).

     The base pay of each  Participant  for each  payroll  period is the regular
straight  time  compensation  earned  during  such  payroll  period,  before any
deductions or  withholdings,  but excluding  overtime,  bonuses,  amount paid as
reimbursement of expenses and other additional compensation.

     1.9     Change in Payroll Deductions

     Deductions  may  be  decreased  only  once  in  a  Payment  Period.  A  new
Authorization will be required and must be received in the Corporate Secretary's
office no later than six (6) days prior to the individual's pay date.

     1.10    Withdrawal from the Plan

     An employee may withdraw  from the Plan,  in whole but not in part,  at any
time prior to the last  business  day of each  Payment  Period by  delivering  a
Withdrawal  Notice  to the  Corporate  Secretary's  office,  in which  event the
Company will refund the entire balance of his or her deductions not  theretofore
used to purchase stock under the Plan within thirty (30) days following  receipt
of the Withdrawal Notice.

     An employee  who  withdraws  from the Plan will be treated like an employee
who has never  entered  the  Plan.  To  re-enter,  an  employee  must file a new
Authorization  at least  ten (10) days  before  the  beginning  date of the next
Payment Period which cannot,  however,  become effective before the beginning of
the next Payment Period following withdrawal.

     1.11   Issuance of Stock

     Certificates for stock issued to  participants,  or to a broker for benefit
of  participants,  will be delivered as soon as  practicable  after each Payment
Period.

     Stock  purchased  under  the Plan  will be  issued  only in the name of the
employee, or if the Authorization so specifies,  in the name of the employee and
another person of legal age as joint tenants with rights of survivorship.

     In order to obtain  the tax  treatment  provided  by the Code for  employee
stock  purchase  plans within the meaning of Section 423 of the Code, the shares
of stock  received  after the end of each Payment  Period may not be sold by the
employee  until  after a date  which is the later of two (2) years from the date
that the option to  purchase  such  shares is granted  (pursuant  to Section 1.4
hereof)  and one (1) year from the date that the shares are  transferred  to the
employee.  Sale or other  disposition of such shares prior to such date may give
rise to federal  income tax and  Federal  Insurance  Contribution  Act  ("FICA")
withholding obligations on the part of the Company. Accordingly, if certificates
representing  shares are issued to employees  upon  exercise of options  granted
hereunder,  they will bear a legend  restricting  transfer  prior to such  date,
unless the employee shall have reimbursed the Company for any federal income tax
and FICA withholding obligations arising out of the transaction.

     1.12   No Transfer or Assignment of Employee's Rights

     An employee's rights under the Plan are the employee's alone and may not be
transferred  or  assigned  to, or availed of by,  any other  person.  Any option
granted to an employee may be exercised only by such employee.

     1.13   Termination of Employee's Rights

     An employee's  rights under the Plan will terminate when he ceases to be an
employee because of resignation,  retirement,  lay-off,  discharge, or change of
status. A Withdrawal  Notice will be considered as having been received from the
employee on the day his or her employment ceases, and all payroll deductions not
used will be refunded.

     If an  employee's  employment  shall be  terminated  by  reason of death or
disability prior to the end of the current Payment Period,  the employee (his or
her designated  beneficiary,  in the event of his death,  or if none, his or her
legal  representative) shall have the right, within ninety (90) days thereafter,
to elect to have the  balance in his or her account  either  refunded in cash or
applied at the end of the current  Payment  Period toward the purchase of Common
Stock.

     1.14   Termination and Amendments to Plan

     The Plan may be terminated at any time by the Company's Board of Directors.
It will  terminate  in any case when all or  substantially  all of the  unissued
shares of Common Stock reserved for the purpose of the Plan have been purchased.
If at any time  shares of stock  reserved  for the  purposes  of the Plan remain
available for purchase but not in sufficient number to satisfy all then unfilled
purchase   requirements,   the  available  shares  shall  be  apportioned  among
participants in proportion to their options and the Plan shall  terminate.  Upon
such  termination or any other  termination of the Plan, all payroll  deductions
not used to purchase stock will be refunded.

     The Board of Directors  also reserves the right to amend the Plan from time
to time, in any respect, provided, however, that no amendment shall be effective
without prior approval of the  stockholders,  which would (a) except as provided
in Paragraphs  1.3 and 1.4,  increase the number of shares of Common Stock to be
offered above or (b) change the class of employees  eligible to receive  options
under the Plan.

     1.15   Limitations on Sale of Stock Purchased Under the Plan

     The Plan is intended to provide  Common  Stock for  investment  and not for
resale.  The Company  does not,  however,  intend to restrict or  influence  any
employee in the conduct of his own affairs.  An employee  may,  therefore,  sell
stock purchased under the Plan at any time, provided,  however,  that because of
certain  Federal  tax  requirements,  each  employee  will agree by signing  the
Authorization  to promptly give the Company notice of any such stock disposed of
within one (1) year after the date of the last day of the Payment  Period during
which the stock was purchased indicating the number of such shares disposed. The
employee assumes the risk of any market fluctuations in the price of such stock.

     1.16 Company's Payment of Expenses Related to the Plan

     The Company will bear all costs of administering and carrying out the Plan.

     1.17 Participating Subsidiaries

     The term  "participating  subsidiaries"  shall mean any  subsidiary  of the
Company  which is  designated  by the Board of Directors to  participate  in the
Plan.  The Board of  Directors  shall  have the  power to make such  designation
before or after the Plan is approved by the stockholders.

     1.18 Administration of the Plan

     The Plan shall be  administered  by a committee  appointed  by the Board of
Directors of the Company (the  "Committee").  The Committee shall consist of not
less than three (3) members of the Company's  Board of  Directors.  The Board of
Directors  may from time to time  remove  members  from,  or add members to, the
Committee.  Vacancies on the Committee,  however caused,  shall be filled by the
Board of Directors.  The Committee  shall select one of its members as Chairman,
and shall hold meetings at such times and places as it may determine.  Acts by a
majority  of the  Committee,  or acts  reduced  to or  approved  in writing by a
majority  of the  members  of the  Committee,  shall  be the  valid  acts of the
Committee.  No member of the Committee  shall be eligible to  participate in the
Plan while serving as a member of the Committee.

     The  interpretation  and construction by the Committee of any provisions of
the Plan or of any  option  granted  under it  shall be final  unless  otherwise
determined by the Board of Directors.  The Committee may from time to time adopt
such rules and  regulations  for carrying  out the Plan as it may deem best.  No
member of the Board of Directors or the Committee shall be liable for any action
or  determination  made in good  faith  with  respect  to the Plan or any option
granted under it.

     1.19   Optionees Not Stockholders

     Until such time as the applicable Common Stock is actually purchased by and
issued to an employee  pursuant to the Plan,  no employee  shall be considered a
shareholder  or have  shareholder  rights  merely by reason of  tendering to the
Company an Authorization  and,  therefore,  instituting  payroll  deductions and
related actions.

     1.20   Application of Funds

     The proceeds received by the Company from the sale of Common Stock pursuant
to options granted under the Plan will be used for general corporate purposes.

     1.21   Governmental Regulation

     The Company's obligation to sell and deliver shares of the Company's Common
Stock under this Plan is subject to the approval of any  governmental  authority
required in connection with the  authorization,  issuance or sale of such Common
Stock.

     1.22   Withholding of Additional Federal Income Tax

     In  accordance  with Section  3402(a) of the Code and the  regulations  and
rulings  promulgated  thereunder,  the Company will  withhold  from the wages of
participating  employees,  in all  payroll  periods  following  and in the  same
calendar  year as the date on  which  compensation  is  deemed  received  by the
employee,  additional income taxes in respect of amounts deemed  compensation to
be included as includible gross income reported by the employee.

     1.23   Approval of Stockholders

     The Plan shall not take effect until  approved by the holders of a majority
of the  outstanding  shares of Common Stock of the Company,  which approval must
occur within the period  beginning  twelve (12) months  before and ending twelve
(12) months after the date the Plan is adopted by the Board of Directors.
