Item 1.  DESCRIPTION OF SECURITIES TO BE REGISTERED. 

     On March 12, 1998, the Board of Directors (the "Board") of Data I/O 
Corporation (the "Corporation") declared a dividend distribution of one 
preferred share purchase right (a "Right") for each outstanding share of 
Common Stock (the "Common Stock") of the Corporation.  The dividend is 
payable to the shareholders of record on April 4, 1998 (the "Record Date"), 
the expiration date of the Corporation's existing Shareholder Rights Plan, 
and with respect to shares of Common Stock issued thereafter until the 
Distribution Date (as defined below) and, in certain circumstances, with 
respect to shares of Common Stock issued after the Distribution Date.  Except 
as set forth below, each Right, when it becomes exercisable, entitles the 
registered holder to purchase from the Corporation one one-hundredth 
(1/100th) of a share of Series A Junior Participating Preferred Stock of the 
Corporation, having the relative rights, preferences and limitations set 
forth in the Form of Certificate of Designation, Preferences and Rights of 
Series A Junior Participating Preferred Stock (the "Preferred Stock") filed 
as Exhibit A to Exhibit 1 to the Registration Statement on Form 8-A filed by 
the Corporation with the Securities and Exchange Commission on April 5, 1988, 
at a price of $30 per one one-hundredth (1/100th) of a share of Preferred 
Stock (the "Purchase Price"), subject to adjustment.  The description and 
terms of the Rights are set forth in a Rights Agreement (the "Rights 
Agreement") between the Corporation and ChaseMellon Shareholder Services, 
L.L.C., as Rights Agent (the "Rights Agent"), dated as of April 4, 1998.  The 
Preferred Stock was authorized in connection with the adoption of the 
Corporation's existing Shareholder Rights Plan and no shares of the Preferred 
Stock have been issued.

     Initially, the Rights will be attached to certificates representing 
shares of Common Stock then outstanding, and no separate certificates 
representing the Rights ("Right Certificates") will be distributed.  The 
Rights will separate from the Common Stock upon the earlier to occur of (i) a 
person or group of affiliated or associated persons having acquired, without 
the prior approval of the Corporation's Board of Directors, beneficial 
ownership of 15% or more of the outstanding shares of Common Stock or (ii) 10 
days, or such later date as the Board may determine, following the 
commencement of or announcement of an intention to make, a tender offer or 
exchange offer the consummation of which would result in a person or group of 
affiliated or associated persons becoming an Acquiring Person (as hereinafter 
defined) except pursuant to a Permitted Offer (as hereinafter defined) (the 
"Distribution Date").  A person or group whose acquisitions of shares of 
Common Stock cause a Distribution Date pursuant to clause (i) above is an 
"Acquiring Person," with certain exceptions as set forth in the Rights 
Agreement.  The date that a person or group is first publicly announced to 
have become such by the Corporation or such Acquiring Person is the "Shares 
Acquisition Date."

                                      2



     The Rights Agreement provides that, until the Distribution Date, the 
Rights will be transferred with and only with the associated shares of Common 
Stock. Until the Distribution Date (or earlier redemption or expiration of 
the Rights), new Common Stock certificates issued after the Record Date upon 
transfer or new issuance of shares of Common Stock will contain a notation 
incorporating the Rights Agreement by reference.  Until the Distribution Date 
(or earlier redemption or expiration of the Rights), the surrender for 
transfer of any certificates for shares of Common Stock outstanding as of the 
Record Date, even without attaching thereto such notation or a copy of the 
Summary of Rights attached to the Rights Agreement as Exhibit B, will also 
constitute the transfer of the Rights associated with the shares of Common 
Stock represented by such certificate.  As soon as practicable following the 
Distribution Date Right Certificates will be mailed to the holders of record 
of shares of the Common Stock as of the Close of Business (as defined in the 
Rights Agreement) on the Distribution Date (and to each initial record holder 
of certain shares of Common Stock issued after the Distribution Date), and 
such separate Right Certificates alone will evidence the Rights.

     The Rights are not exercisable until the Distribution Date and will 
expire at the close of business on April 4, 2008, unless earlier redeemed by 
the Corporation as described below.

     In the event that any person becomes an Acquiring Person (except 
pursuant to a tender or exchange offer which is for all outstanding shares of 
Common Stock at a price and on terms which a majority of certain members of 
the Board determines to be adequate and in the best interests of the 
Corporation, its shareholders and other relevant constituencies, other than 
such Acquiring Person, its affiliates and associates (a "Permitted Offer")), 
each holder of a Right will thereafter have the right (the "Flip-In Right") 
to receive upon exercise the number of shares of Common Stock (or, in certain 
circumstances, of one one-hundredths (1/100ths) of a share of Preferred Stock 
or other securities of the Corporation) having a value (immediately prior to 
such triggering event) equal to two times the then-applicable Purchase Price 
of the Right. Notwithstanding the foregoing, following the occurrence of the 
event described above, all Rights that are, or (under certain circumstances 
specified in the Rights Agreement) were, beneficially owned by any Acquiring 
Person or any affiliate or associate thereof will be null and void.  The 
Board has the option, at any time after any person becomes an Acquiring 
Person, to exchange all or part of the then-exercisable Rights (excluding 
those that have become void, as described in the immediately preceding 
sentence) for shares of Common Stock, at an exchange ratio determined by 
dividing the then-applicable Purchase Price by the then-current market price 
per share of Common Stock as determined in accordance with the Rights 
Agreement.  However, this option generally terminates if any person becomes 
the beneficial owner of 50% or more of the Common Stock.


                                      3



     In the event that, at any time following the Shares Acquisition Date, 
(i) the Corporation is acquired in a merger or other business combination 
transaction in which the holders of all of the outstanding shares of Common 
Stock immediately prior to the consummation of the transaction are not the 
holders of all of the surviving corporation's voting power, or (ii) more than 
50% of the Corporation's assets or earning power is sold or transferred, in 
either case with or to (x) an Acquiring Person or any affiliate or associate 
thereof or (y) any other person in which such Acquiring Person, affiliate or 
associate has an interest or any person acting on behalf of or in concert 
with such Acquiring Person, affiliate or associate, or (z) if, in such 
transaction, all holders of shares of Common Stock are not treated alike, any 
other person, then each holder of a Right (except Rights which previously 
have been voided as set forth above) shall thereafter have the right (the 
"Flip-Over Right") to receive, upon exercise, common shares of the acquiring 
company (or, in certain circumstances, its parent) having a value equal to 
two times the exercise price of the Right.  The holder of a Right will 
continue to have the Flip-Over Right whether or not such holder exercises or 
surrenders the Flip-In Right.

     The Purchase Price payable, and the number of shares of Preferred Stock, 
shares of Common Stock or other securities issuable, upon exercise of the 
Rights are subject to adjustment from time to time to prevent dilution (i) in 
the event of a stock dividend on, or a subdivision, combination or 
reclassification of, the Preferred Stock, (ii) upon the grant to holders of 
shares of the Preferred Stock of certain rights or warrants to subscribe for 
or purchase shares of Preferred Stock at a price, or securities convertible 
into Preferred Stock with a conversion price, less than the then current 
market price of the Preferred Stock or (iii) upon the distribution to holders 
of shares of the Preferred Stock of evidences of indebtedness or assets 
(excluding regular quarterly cash dividends) or of subscription rights or 
warrants (other than those referred to above).

     The number of outstanding Rights and the number of one one-hundredths 
(1/100ths) of a share of Preferred Stock issuable upon exercise of each Right 
are also subject to adjustment in the event of a stock split of the Common 
Stock or a stock dividend on the Common Stock payable in Common Stock or 
subdivisions, consolidations or combinations of the Common Stock occurring, 
in any such case, prior to the Distribution Date.

     With certain exceptions, no adjustment in the Purchase Price will be 
required until cumulative adjustments require an adjustment of at least 1% in 
such Purchase Price.

     At any time prior to the earlier to occur of (i) a person becoming an 
Acquiring Person or (ii) the expiration of the Rights, and under certain 
other circumstances, the Corporation may redeem the Rights in whole, but not 
in part, at a price (payable in cash or, at the Corporation's election, in 
Common Stock) of $.001 per Right (the "Redemption Price"), which redemption 
shall be effective upon the action of the Board.  Additionally, 

                                      4



following the Shares Acquisition Date, the Corporation may redeem the then 
outstanding Rights in whole, but not in part, at the Redemption Price, 
provided that such redemption is in connection with a merger or other 
business combination transaction or series of transactions involving the 
Corporation in which all holders of shares of Common Stock are treated alike 
but not involving an Acquiring Person or its affiliates or associates.

     Other than those provisions relating to the rights, duties and 
obligations of the Rights Agent and certain principal economic terms of the 
Rights, all of the provisions of the Rights Agreement may be amended by the 
Board prior to the Distribution Date.  After the Distribution Date, the 
provisions of the Rights Agreement may be amended by the Board in order to 
cure any ambiguity, defect or inconsistency, to make changes that do not 
adversely affect the interests of holders of Rights (excluding the interests 
of any Acquiring Person), or, subject to certain limitations, to shorten or 
lengthen any time period under the Rights Agreement.

     Until a Right is exercised, the holder thereof, as such, will have no 
rights as a shareholder of the Corporation, including, without limitation, 
the right to vote or to receive dividends.  While the distribution of the 
Rights will not be taxable to shareholders of the Corporation, shareholders 
may, depending upon the circumstances, recognize taxable income should the 
Rights become exercisable or upon the occurrence of certain events thereafter.

     This summary description of the Rights does not purport to be complete 
and is qualified in its entirety by reference to the Rights Agreement, which 
is hereby incorporated herein by reference. 

     As of March 12, 1998, there were 7,135,157 shares of Common Stock 
outstanding.  Each share of Common Stock outstanding on the Record Date will 
receive one Right.  As long as the Rights are attached to the shares of 
Common Stock, the Corporation will issue one Right with each new share of 
Common Stock so that all such shares will have attached rights. 

     The Rights have certain anti-takeover effects.  The Rights will cause 
substantial dilution to a person or group that attempts to acquire the 
Corporation without conditioning the offer on the Rights being redeemed or a 
substantial number of Rights being acquired.  However, the Rights should not 
interfere with any tender offer or merger approved by the Corporation (other 
than with an Acquiring Person) because the Rights do not become exercisable 
in the event of a Permitted Offer or other acquisition exempted by the Board.
