Item 5. OTHER EVENTS.

On March 12, 1998, Data I/O Corporation (the "Corporation") issued a press release relating to the adoption by the Board of Directors (the "Board") of a Shareholder Rights Plan which goes into effect on April 4, 1998, the expiration date of the Corporation's existing Shareholder Rights Plan. The March 12, 1998 press release of the Corporation is attached hereto as Exhibit 99.1. The Corporation's existing Shareholder Rights Plan, as currently in effect, is attached hereto as Exhibit 4.2.

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") 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

2

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."

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

3

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.

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.

4

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, 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 of Directors of the Corporation 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

5

not become exercisable in the event of a Permitted Offer or other acquisition exempted by the Board.

Attached hereto as Exhibit 4.1 and incorporated herein by reference are copies of the Rights Agreement and the exhibits thereto, as follows: Exhibit A -- Form of Right Certificate; and Exhibit B -- Summary of Rights to Purchase Series A Junior Participating Preferred Stock. The foregoing description of the Rights is qualified in its entirety by reference to the Rights Agreement and such exhibits thereto.

RIGHTS AGREEMENT

This RIGHTS AGREEMENT (this "AGREEMENT") is made as of this 4th day of April, 1998 by and between Data I/O Corporation, a Washington corporation (the "CORPORATION"), and ChaseMellon Shareholder Services, L.L.C., a New Jersey limited liability company (the "RIGHTS AGENT"), with respect to the following facts and circumstances.

A. The Board of Directors of the Corporation has authorized and declared a dividend of one preferred share purchase right (a "RIGHT") for each share of Common Stock (as hereinafter defined) of the Corporation outstanding at the Close of Business (as hereinafter defined) on April 4, 1998 (the "RECORD DATE"), each Right representing the right to purchase one one-hundredth (1/100th) of a share of Preferred Stock (as hereinafter defined), upon the terms and subject to the conditions herein set forth.

B. The Board of Directors of the Corporation has further authorized and directed the issuance of one Right with respect to each share of Common Stock that shall become outstanding between the Record Date and the earliest of the Distribution Date, the Redemption Date or the Final Expiration Date (as such terms are hereinafter defined); PROVIDED, HOWEVER, that Rights may be issued with respect to shares of Common Stock that shall become outstanding after the Distribution Date and prior to the earlier of the Redemption Date and the Final Expiration Date in accordance with the provisions of Section 22 of this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual agreements herein set forth, the parties hereby agree as follows:

"ACQUIRING PERSON" means any Person who or which, together with all Affiliates and Associates of such Person, without the prior approval of the Corporation's Board of Directors, shall be the Beneficial Owner of 15% or more of the then outstanding shares of Common Stock (other than as a result of a Permitted Offer) or was such a Beneficial Owner at any time after the date hereof, whether or not such person continues to be the Beneficial Owner of 15% or more of the then outstanding shares of Common Stock. Notwithstanding the foregoing: (A) the term "Acquiring Person" shall not include (i) the Corporation, (ii) any Subsidiary of the Corporation, (iii) any employee benefit plan of the Corporation or of any Subsidiary of the Corporation, (iv) any Person or entity organized, appointed or established by the Corporation or any Subsidiary of the Corporation for or pursuant to the terms of any such plan, or (v) any Person who or which, together with all Affiliates and Associates of such Person, becomes the Beneficial Owner of 15% or more of the then outstanding shares of Common Stock


as a result of the acquisition of shares of Common Stock directly from the Corporation; and (B) no Person shall be deemed to be an "Acquiring Person" either (i) as a result of the acquisition of Common Stock by the Corporation which, by reducing the number of shares of Common Stock outstanding, increases the proportional number of shares beneficially owned by such Person together with all Affiliates and Associates of such Person; PROVIDED, HOWEVER, that if (X) a Person would become an Acquiring Person (but for the operation of this subclause (B)(i)) as a result of the acquisition of shares of Common Stock by the Corporation, and (Y) after such share acquisition by the Corporation, such Person, or an Affiliate or Associate of such Person, becomes the Beneficial Owner of any additional shares of Common Stock, then such Person shall be deemed an Acquiring Person, or (ii) if (X) within eight
(8) days after such Person would otherwise have become an Acquiring Person (but for the operation of this subclause (B)(ii)), such Person notifies the Board of Directors of the Corporation that such Person did so inadvertently and (Y) within two (2) days after such notification, such Person is the Beneficial Owner of less than 15% of the outstanding shares of Common Stock.

1.2. "ACT" means the Securities Act of 1933, as amended.

1.7.1. such Person or any of such Person's Affiliates or Associates beneficially owns, directly or indirectly;

1.7.2. such Person or any of such Person's Affiliates or Associates has (A) the right to acquire (whether such right is exercisable immediately or only after the passage of time) pursuant to any agreement, arrangement or understanding, or upon the exercise of

2

conversion rights, exchange rights, rights (other than the Rights), warrants or options, or otherwise; PROVIDED, HOWEVER, that a Person shall not be deemed the Beneficial Owner of, or to beneficially own, securities tendered pursuant to a tender or exchange offer made by or on behalf of such Person or any of such Person's Affiliates or Associates until such tendered securities are accepted for purchase or exchange; or (B) the right to vote pursuant to any agreement, arrangement or understanding; PROVIDED, HOWEVER, that a Person shall not be deemed the Beneficial Owner of, or to beneficially own, any security if the agreement, arrangement or understanding to vote such security
(1) arises solely from a revocable proxy or consent given to such Person in response to a public proxy or consent solicitation made pursuant to, and in accordance with, the applicable rules and regulations promulgated under the Exchange Act and (2) is not also then reportable on Schedule 13D under the Exchange Act (or any comparable or successor report); or

1.7.3. are beneficially owned, directly or indirectly, by any other Person (or any Affiliate or Associate thereof) with which such Person (or any of such Person's Affiliates or Associates) has any agreement, arrangement or understanding relating to the acquisition, holding, voting (except to the extent contemplated by the proviso to subclause (B) of Section 1.7.2), or disposing of any securities of the Corporation.

Notwithstanding anything in this Section 1.7 to the contrary, the phrase "then outstanding," when used with reference to a Person's Beneficial Ownership of securities of the Corporation, shall mean the number of such securities then issued and outstanding together with the number of such securities not then actually issued and outstanding which such Person would be deemed to own beneficially hereunder.

Notwithstanding anything in this Section 1.7 to the contrary, no Person shall be deemed to beneficially own any securities solely by reason of such Person being a party to a customary agreement pursuant to which such Person acts or agrees to act as an underwriter with respect to a bona fide public offering of securities.

No decision reached, or action taken, by the Board of Directors of the Corporation or any committee thereof shall cause any Person (or any Affiliate or Associate of such Person) who is a member of the Board of Directors of the Corporation or such committee to be deemed, for the purposes of this Agreement, to be a Beneficial Owner of any securities beneficially owned by any other Person (or any Affiliate or Associate of such Person) who is a member of the Board of Directors of the Corporation or any committee thereof solely by reason of such membership of the Board of Directors or any committee thereof or participation in the decisions or actions thereof on the part of either or both of such Persons.

3. ISSUANCE OF RIGHT CERTIFICATES.

3.1. Until the earlier of (i) the Shares Acquisition Date or (ii) the Close of Business on the tenth (10th) day (or such later date as may be determined by action of the Corporation's Board of Directors) after the date of the commencement by any Person (other than the Corporation, any Subsidiary of the Corporation, any employee benefit plan of the Corporation or of any Subsidiary of the Corporation or any Person or entity organized, appointed or established by the Corporation or any Subsidiary of the Corporation for or pursuant to the terms of any such plan) of, or after the date of the first public announcement of the intention of any Person (other than the Corporation, any Subsidiary of the Corporation, any employee benefit plan of the Corporation or of any Subsidiary of the Corporation or any Person or entity organized, appointed or established by the Corporation or any Subsidiary of the Corporation for or pursuant to the terms of any such plan) to commence (which intention to commence remains in effect for five (5) Business Days after such announcement), a tender or exchange offer the consummation of which would result in any Person becoming an Acquiring Person (including, in the case of both (i) and (ii), any such date which is after the date of this Agreement and prior to the issuance of the Rights) (the "DISTRIBUTION DATE"), (x) the Rights will be evidenced (subject to the provisions of Section 3.2 hereof) by the certificates for shares of Common Stock registered in the names of the holders thereof (which certificates shall also be deemed to be Right Certificates) and not by separate Right Certificates, and (y) the right to receive Right Certificates will be transferable only in connection with the transfer of the underlying shares of Common Stock (including a transfer to the Corporation); PROVIDED, HOWEVER, that if a tender or exchange offer is terminated prior to the occurrence of a Distribution Date, then no Distribution Date shall occur as a result of such tender or exchange offer. As soon as practicable after the Distribution Date, the Corporation will prepare and execute, the Rights Agent will countersign, and the Corporation will send or cause to be sent by first-class, postage-prepaid mail, to each record holder of shares of Common Stock as of the Close of Business on the Distribution Date, at the address of such holder shown on the records of the Corporation, a Right Certificate, substantially in the form of Exhibit A hereto (a "RIGHT CERTIFICATE"), evidencing one Right for each share of Common Stock so held. As of and after the Distribution Date, the Rights will be evidenced solely by such Right Certificates.

3.2. As promptly as practicable following the Record Date, the Corporation will send a copy of a Summary of Rights to Purchase Preferred Stock, in substantially the form of Exhibit B hereto (the "SUMMARY OF RIGHTS"), by first-class, postage-prepaid mail, to each record holder of shares of Common Stock as of the Close of Business on the Record Date, at the address of such holder shown on the records of the Corporation. With respect to certificates for shares of Common Stock outstanding as of the Record Date, until the Distribution Date the Rights will be evidenced by such certificates registered in the names of the holders thereof together with a copy of the Summary of Rights attached thereto. Until the Distribution Date (or the earlier of the Redemption Date or the Final Expiration Date), the surrender for transfer of any certificate for shares of Common Stock outstanding on the Record Date, with or without a copy

7

of the Summary of Rights attached thereto, shall also constitute the transfer of the Rights associated with such shares of Common Stock.

3.3. Certificates for shares of Common Stock that become outstanding (including, without limitation, reacquired shares of Common Stock referred to in the last sentence of this Section 3.3) after the Record Date but prior to the earliest of the Distribution Date, the Redemption Date or the Final Expiration Date, shall be deemed also to be certificates for Rights, and shall bear the following legend:

This certificate also evidences and entitles the holder hereof to certain rights as set forth in a Rights Agreement between Data I/O Corporation and ChaseMellon Shareholder Services, L.L.C., a New Jersey limited liability company, as Rights Agent, dated as of April 4, 1998 (the "Rights Agreement"), the terms of which are hereby incorporated herein by reference and a copy of which is on file at the principal executive offices of Data I/O Corporation. Under certain circumstances, as set forth in the Rights Agreement, such Rights will be evidenced by separate certificates and will no longer be evidenced by this certificate. Data I/O Corporation will mail to the holder of this certificate a copy of the Rights Agreement without charge after receipt of a written request therefor. Under certain circumstances set forth in the Rights Agreement, Rights issued to, or held by, any Person who is, was or becomes an Acquiring Person or an Affiliate or Associate thereof (as defined in the Rights Agreement) and certain related persons, whether currently held by or on behalf of such Person or by any subsequent holder, may become null and void.

With respect to such certificates containing the foregoing legend, until the Distribution Date the Rights associated with the shares of Common Stock represented by such certificates shall be evidenced by such certificates alone, and the surrender for transfer of any such certificate shall also constitute the transfer of the Rights associated with the shares of Common Stock represented thereby. In the event that the Corporation purchases or acquires any shares of Common Stock after the Record Date but prior to the Distribution Date (or the earlier of the Redemption Date or the Final Expiration Date), any Rights associated with such shares of Common Stock shall be deemed cancelled and retired so that the Corporation shall not be entitled to exercise any Rights associated with the Common Stock that are no longer outstanding.

4. FORM OF RIGHT CERTIFICATE.

4.1. The Right Certificates (and the forms of election to purchase and of assignment to be printed on the reverse thereof) shall be substantially in the form set forth in Exhibit A hereto and may have such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Corporation may deem appropriate (which

8

may not affect the duties and responsibilities of the Rights Agent) and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange on which the Rights may from time to time be listed, or to conform to usage. Subject to the provisions of Section 11 and Section 22 hereof, the Right Certificates shall entitle the holders thereof to purchase such number of one one-hundredths (1/100ths) of a share of Preferred Stock as shall be set forth therein at the price per one one-hundredth (1/100th) of a share of Preferred Stock set forth therein (the "PURCHASE PRICE"), but the amount and type of securities purchasable upon the exercise of each Right and the Purchase Price thereof shall be subject to adjustment as provided herein.

4.2. Any Right Certificate issued pursuant to Section 3.1 or
Section 22 hereof that represents Rights that are null and void pursuant to
Section 7.6 of this Agreement and any Right Certificate issued pursuant to
Section 6 or Section 11 hereof upon transfer, exchange, replacement or adjustment of any other Right Certificate referred to in this sentence, shall contain (to the extent feasible and upon notice by the Corporation to the Rights Agent that this Section 4.2 has become applicable) the following legend:

The Rights represented by this Right Certificate are or were beneficially owned by a Person who was or became an Acquiring Person or an Affiliate or Associate of an Acquiring Person (as such terms are defined in the Rights Agreement). Accordingly, this Right Certificate and the Rights represented hereby are null and void.

The provisions of Section 7.6 of this Agreement shall be operative whether or not the foregoing legend is contained on any such Right Certificate.

5. COUNTERSIGNATURE AND REGISTRATION.

5.1. The Right Certificates shall be executed on behalf of the Corporation by its President or any Vice President and the Secretary or an Assistant Secretary, either manually or by facsimile signature, shall have affixed thereto the Corporation's seal or a facsimile thereof, and shall be attested by the Secretary or an Assistant Secretary of the Corporation, either manually or by facsimile signature. The Right Certificates shall be countersigned by the Rights Agent and shall not be valid for any purpose unless so countersigned. In case any officer of the Corporation who shall have signed any of the Right Certificates shall cease to be such officer of the Corporation before countersignature by the Rights Agent and issuance and delivery by the Corporation, such Right Certificates may nevertheless be countersigned by the Rights Agent and issued and delivered by the Corporation with the same force and effect as though the person who signed such Right Certificates had not ceased to be such officer of the Corporation; and any Right Certificate may be signed on behalf of the Corporation by any Person who, at the actual date of the execution of such Right Certificate, shall be a proper officer of the Corporation to

9

sign such Right Certificate, although at the date of the execution of this Rights Agreement any such Person was not such an officer.

5.2. Following the Distribution Date, and receipt by the Rights Agent of a list of record holders of Rights, the Rights Agent will keep or cause to be kept, at its office designated pursuant to Section 25 hereof as the appropriate place for surrender or transfer of the Right Certificates, books for registration and transfer of the Right Certificates issued hereunder. Such books shall show the names and addresses of the respective holders of the Right Certificates, the number of Rights evidenced on the face of each of the Right Certificates and the certificate number and the date of each of the Right Certificates.

6. TRANSFER, SPLIT-UP, COMBINATION AND EXCHANGE OF RIGHT CERTIFICATES; MUTILATED, DESTROYED, LOST OR STOLEN RIGHT CERTIFICATES.

6.1. Subject to the provisions of Section 4.2, Section 7.6 and
Section 14 hereof, at any time after the Close of Business on the Distribution Date, and at or prior to the Close of Business on the earlier of the Redemption Date or the Final Expiration Date, any Right Certificate or Right Certificates may be transferred, split up, combined or exchanged for another Right Certificate or Right Certificates, entitling the registered holder to purchase a like number of one one-hundredths (1/100ths) of a share of Preferred Stock (or, following a Triggering Event, other securities, as the case may be) as the Right Certificate or Right Certificates surrendered then entitled such holder (or former holder in the case of a transfer) to purchase. Any registered holder desiring to transfer, split up, combine or exchange any Right Certificate or Right Certificates shall make such request in writing delivered to the Rights Agent, and shall surrender the Right Certificate or Right Certificates to be transferred, split up, combined or exchanged at the office of the Rights Agent designated for such purpose. Neither the Rights Agent nor the Corporation shall be obligated to take any action whatsoever with respect to the transfer of any such surrendered Right Certificate until the registered holder shall have completed and signed the certificate contained in the form of assignment on the reverse side of such Right Certificate and shall have provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates thereof as the Corporation or the Rights Agent shall reasonably request. Thereupon the Rights Agent shall, subject to Section 4.2, Section 7.6 and Section 14 hereof, countersign and deliver to the Person entitled thereto a Right Certificate or Right Certificates, as the case may be, as so requested. The Corporation may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer, split up, combination or exchange of Right Certificates. The Rights Agent may in its sole discretion require the Corporation or the Person entitled to such Right Certificate to provide evidence that such payment has been made prior to countersigning and delivering any Right Certificate pursuant to this Section 6.1.

10

6.2. Upon receipt by the Corporation and the Rights Agent of evidence reasonably satisfactory to them of the loss, theft, destruction or mutilation of a Right Certificate, and, in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to them, and, at the Corporation's request, reimbursement to the Corporation and the Rights Agent of all reasonable expenses incidental thereto, and upon surrender to the Rights Agent and cancellation of the Right Certificate if mutilated, the Corporation will make and deliver a new Right Certificate of like tenor to the Rights Agent for countersignature and delivery to the registered holder in lieu of the Right Certificate so lost, stolen, destroyed or mutilated.

7. EXERCISE OF RIGHTS; PURCHASE PRICE; EXPIRATION DATE OF RIGHTS.

7.1. Subject to Section 7.6 hereof, the registered holder of any Right Certificate may exercise the Rights evidenced thereby (except as otherwise provided herein) in whole or in part at any time after the Distribution Date upon surrender of the Right Certificate, with the form of election to purchase and the certificate on the reverse side thereof duly executed, to the Rights Agent at the office of the Rights Agent designated for such purpose, together with payment of the aggregate Purchase Price for the total number of one one-hundredths (1/100ths) of a share of Preferred Stock (or other securities, as the case may be) as to which such surrendered Rights are exercised, at or prior to the earlier of (i) the Close of Business on April 4, 2008 (the "FINAL EXPIRATION DATE"), or (ii) the time at which the Rights are redeemed as provided in Section 23 hereof (the "REDEMPTION DATE").

7.2. The Purchase Price for each one one-hundredth (1/100th) of a share of Preferred Stock pursuant to the exercise of a Right shall initially be $30, shall be subject to adjustment from time to time as provided in the next sentence and in Sections 11 and 13.1 hereof and shall be payable in accordance with paragraph 7.3 below. Anything in this Agreement to the contrary notwithstanding, in the event that at any time after the date of this Agreement and prior to the Distribution Date, the Corporation shall (i) declare or pay any dividend on the Common Stock payable in Common Stock or
(ii) effect a subdivision, combination or consolidation of the Common Stock (by reclassification or otherwise than by payment of dividends in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then, in any such case, each share of Common Stock outstanding following such subdivision, combination or consolidation shall continue to have a Right associated therewith and the Purchase Price following any such event shall be proportionately adjusted to equal the result obtained by multiplying the Purchase Price immediately prior to such event by a fraction the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior to the occurrence of the event and the denominator of which shall be the total number of shares of Common Stock outstanding immediately following the occurrence of such event. The adjustment provided for in the preceding sentence shall be made successively whenever such a dividend is declared or paid or such a subdivision, combination or consolidation is effected.

11

7.3. Upon receipt of a Right Certificate representing exercisable Rights, with the form of election to purchase and the certificate on the reverse side thereof duly executed, accompanied by payment of the Purchase Price for the Preferred Stock (or other securities, as the case may be) to be purchased and an amount equal to any applicable tax or governmental charge required to be paid by the holder of such Right Certificate in accordance with Section 6 hereof by certified check, cashier's check or money order payable to the order of the Corporation, the Rights Agent shall thereupon promptly (i) (A) requisition from any transfer agent of the Preferred Stock certificates for the number of shares of Preferred Stock to be purchased, and the Corporation hereby irrevocably authorizes its transfer agent to comply with all such requests, or (B) if the Corporation, in its sole discretion, shall have elected to deposit the Preferred Stock issuable upon exercise of the Rights hereunder into a depositary, requisition from the depositary agent depositary receipts representing such number of one one-hundredths (1/100ths) of a share of Preferred Stock as are to be purchased (in which case certificates for the Preferred Stock represented by such receipts shall be deposited by the transfer agent with the depositary agent) and the Corporation will direct the depositary agent to comply with such requests,
(ii) when appropriate, requisition from the Corporation the amount of cash to be paid in lieu of issuance of fractional shares in accordance with Section 14 hereof, (iii) after receipt of such certificates or depositary receipts, cause the same to be delivered to or upon the order of the registered holder of such Right Certificate, registered in such name or names as may be designated by such holder, and (iv) when appropriate, after receipt thereof, deliver such cash to or upon the order of the registered holder of such Right Certificate. In the event that the Corporation is obligated to issue other securities (including shares of Common Stock) of the Corporation pursuant to
Section 11.1 hereof, the Corporation will make all arrangements necessary so that such other securities are available for distribution by the Rights Agent, if and when necessary to comply with this Agreement.

7.4. In addition, in the case of an exercise of the Rights by a holder pursuant to Section 11.1.2, the Rights Agent shall return such Right Certificate to the registered holder thereof after imprinting, stamping or otherwise indicating thereon that the Rights represented by such Right Certificate no longer include the rights provided by Section 11.1.2 of the Rights Agreement and if less than all the Rights represented by such Right Certificate were so exercised, the Rights Agent shall indicate on the Right Certificate the number of Rights represented thereby that continue to include the rights provided by Section 11.1.2.

7.5. In case the registered holder of any Right Certificate shall exercise less than all the Rights evidenced thereby, a new Right Certificate evidencing Rights equivalent to the Rights remaining unexercised shall be issued by the Rights Agent to the registered holder of such Right Certificate or to his duly authorized assigns, subject to the provisions of Section 6 and
Section 14 hereof, or the Rights Agent shall place an appropriate notation on the Right Certificate with respect to those Rights exercised.

7.6. Notwithstanding anything in this Agreement to the contrary, from and after the first occurrence of a Section 11.1.2 Event, any Rights beneficially owned by (i) an Acquiring

12

Person or an Affiliate or Associate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or of any Affiliate or Associate thereof) who becomes a transferee after the Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person (or of any Affiliate or Associate thereof) who becomes a transferee prior to or concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person (or from any Affiliate or Associate thereof) to holders of equity interests in such Acquiring Person or to any Person with whom the Acquiring Person has a continuing agreement, arrangement or understanding regarding the transferred Rights or (B) a transfer that the Board of Directors of the Corporation has determined is part of a plan, arrangement or understanding that has as a primary purpose or effect the avoidance of this Section 7.6, shall become null and void without any further action and no holder of such Rights shall have any rights whatsoever with respect to such Rights, whether under any provision of this Agreement or otherwise. The Corporation shall notify the Rights Agent when this Section 7.6 applies and shall use all reasonable efforts to insure that the provisions of this Section 7.6 and Section 4.2 hereof are complied with, but neither the Corporation nor the Rights Agent shall have any liability to any holder of Right Certificates or other Person as a result of the Corporation's failure to make any determinations with respect to an Acquiring Person or its Affiliates, Associates or transferees hereunder.

7.7. Notwithstanding anything in this Agreement to the contrary, neither the Rights Agent nor the Corporation shall be obligated to undertake any action with respect to a registered holder upon the occurrence of any purported exercise as set forth in this Section 7 unless such registered holder shall have (i) properly completed and signed the certificate contained in the form of election to purchase set forth on the reverse side of the Right Certificate surrendered for such exercise, and (ii) provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates thereof as the Corporation or the Rights Agent shall reasonably request.

8. CANCELLATION AND DESTRUCTION OF RIGHT CERTIFICATES.

8.1. All Right Certificates surrendered for the purpose of exercise, transfer, split up, combination or exchange shall, if surrendered to the Corporation or to any of its agents, be delivered to the Rights Agent for cancellation or in cancelled form, or, if surrendered to the Rights Agent, shall be cancelled by it, and no Right Certificates shall be issued in lieu thereof except as expressly permitted by the provisions of this Rights Agreement. The Corporation shall deliver to the Rights Agent for cancellation and retirement, and the Rights Agent shall so cancel and retire, any other Right Certificate purchased or acquired by the Corporation otherwise than upon the exercise thereof. The Rights Agent shall deliver all cancelled Right Certificates to the Corporation, or shall, at the written request of the Corporation, destroy such cancelled Right Certificates, and in such case shall deliver a certificate of destruction thereof to the Corporation.

13

9. RESERVATION AND AVAILABILITY OF PREFERRED STOCK.

9.1. The Corporation covenants and agrees that, at all times prior to the occurrence of a Section 11.1.2 Event, it will cause to be reserved and kept available out of its authorized and unissued Preferred Stock, or any authorized and issued Preferred Stock held in its treasury, the number of shares of Preferred Stock that will be sufficient to permit the exercise in full of all outstanding Rights and, after the occurrence of a Section 11.1.2 Event, shall, to the extent reasonably practicable, so reserve and keep available a sufficient number of shares of Common Stock (and/or other securities) that may be required to permit the exercise in full of the Rights pursuant to this Agreement.

9.2. So long as the shares of Preferred Stock (and, after the occurrence of a Section 11.1.2 Event, shares of Common Stock or any other securities) issuable upon the exercise of the Rights may be listed on any stock exchange, the Corporation shall use its best efforts to cause, from and after such time as the Rights become exercisable, all shares or other securities reserved for such issuance to be listed on such exchange upon official notice of issuance upon such exercise.

9.3. The Corporation covenants and agrees that it will take all such action as may be necessary to ensure that all shares of Preferred Stock
(or shares of Common Stock and/or other securities, as the case may be) delivered upon exercise of Rights shall, at the time of delivery of the certificates for such shares or other securities (subject to payment of the Purchase Price), be duly and validly authorized and issued and fully paid and non-assessable shares or securities.

9.4. The Corporation covenants and agrees that it will pay when due and payable any and all taxes and governmental charges that may be payable in respect of the issuance or delivery of the Right Certificates or of any shares of Preferred Stock (or shares of Common Stock and/or other securities, as the case may be) upon the exercise of Rights. The Corporation shall not, however, be required to pay any tax or governmental charge that may be payable in respect of any transfer or delivery of Right Certificates to a person other than, or the issuance or delivery of certificates or depositary receipts for the shares of Preferred Stock (or shares of Common Stock and/or other securities, as the case may be) in a name other than that of, the registered holder of the Right Certificate evidencing Rights surrendered for exercise, or to issue or to deliver any certificates or depositary receipts for shares of Preferred Stock (or shares of Common Stock and/or other securities, as the case may be) upon the exercise of any Rights, until any such tax or governmental charge shall have been paid (any such tax or governmental charge being payable by the holder of such Right Certificate at the time of surrender) or until it has been established to the Corporation's reasonable satisfaction that no such tax or governmental charge is due.

14

9.5. The Corporation shall use its best efforts to (i) file, as soon as practicable following the Shares Acquisition Date, a registration statement under the Act, with respect to the securities purchasable upon exercise of the Rights on an appropriate form, (ii) cause such registration statement to become effective as soon as practicable after such filing, and
(iii) cause such registration statement to remain effective (with a prospectus at all times meeting the requirements of the Act and the rules and regulations thereunder) until the date of the expiration of the period for exercise of the Rights provided by Section 11.1.2. The Corporation will also take such action as may be appropriate under the blue sky laws of the various states.

10. PREFERRED STOCK RECORD DATE.

10.1. Each Person in whose name any certificate for shares of Preferred Stock (or shares of Common Stock and/or other securities, as the case may be) is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the shares of Preferred Stock
(or shares of Common Stock and/or other securities, as the case may be) represented thereby on, and such certificate shall be dated, the date upon which the Right Certificate evidencing such Rights was duly surrendered and payment of the Purchase Price (and any applicable taxes and governmental charges) was made; PROVIDED, HOWEVER, that, if the date of such surrender and payment is a date upon which the shares of Preferred Stock (or shares of Common Stock and/or other securities, as the case may be) transfer books of the Corporation are closed, such person shall be deemed to have become the record holder of such shares on, and such certificate shall be dated, the next succeeding Business Day on which the shares of Preferred Stock (or shares of Common Stock and/or other securities, as the case may be) transfer books of the Corporation are open.

11. ADJUSTMENT OF PURCHASE PRICE, NUMBER AND KIND OF SHARES OR NUMBER OF RIGHTS.

The Purchase Price, the number and kind of shares covered by each Right and the number of Rights outstanding are subject to adjustment from time to time as provided in this Section 11.

11.1. ADJUSTMENT EVENTS.

11.1.1. In the event the Corporation shall at any time after the date of this Agreement (A) declare a dividend on the Preferred Stock payable in Preferred Stock, (B) subdivide the outstanding Preferred Stock, (C) combine the outstanding Preferred Stock into a smaller number of Preferred Stock or (D) issue any shares of its capital stock in a reclassification of the Preferred Stock (including any such reclassification in connection with a consolidation or merger in which the Corporation is the continuing or surviving corporation), except as otherwise provided in this
Section 11.1 and Section 7.6 hereof, the Purchase Price in effect at the time of the record date for such dividend or of the effective date of such subdivision, combination or reclassification, and the number and kind of shares of capital stock issuable on such date, shall be proportionately adjusted so that the holder of any Right exercised after such time shall be entitled

15

to receive the aggregate number and kind of shares of capital stock that, if such Right had been exercised immediately prior to such date and at a time when the Preferred Stock transfer books of the Corporation were open, such holder would have owned upon such exercise and been entitled to receive by virtue of such dividend, subdivision, combination or reclassification; PROVIDED, HOWEVER, that in no event shall the consideration to be paid upon the exercise of one Right be less than the aggregate par value, if any, of the shares of capital stock of the Corporation issuable upon exercise of one Right. If an event occurs that would require an adjustment under both
Section 11.1.1 and Section 11.1.2, the adjustment provided for in this
Section 11.1.1 shall be in addition to, and shall be made prior to, any adjustment required pursuant to Section 11.1.2.

11.1.2. In the event (a "SECTION 11.1.2 EVENT") that any Person, alone or together with its Affiliates and Associates, shall become an Acquiring Person, then proper provision shall be made so that each holder of a Right (except as provided below and in Section 7.6 hereof) shall, for a period of sixty (60) days (or such longer period as the Corporation's Board of Directors may determine at any time prior to or during such period of sixty (60) days) after the later of the occurrence of any such event or the effective date of an appropriate registration statement under the Act pursuant to Section 9.5 hereof, have a right to receive, upon exercise thereof at a price equal to the then current Purchase Price, in accordance with the terms of this Agreement, such number of shares of Common Stock (or, in the discretion of the Corporation's Board of Directors, one one-hundredths (1/100ths) of a share of Preferred Stock) as shall equal the result obtained by (x) multiplying the then current Purchase Price by the then number of one one-hundredth (1/100th) of a share of Preferred Stock for which a Right was exercisable immediately prior to the first occurrence of a Section 11.1.2 Event, and (y) dividing that product by 50% of the then current per share market price of the Common Stock (determined pursuant to Section 11.4 hereof) on the date of such first occurrence (such number of shares being referred to as the "ADJUSTMENT SHARES"); PROVIDED, HOWEVER, that if the transaction that would otherwise give rise to the foregoing adjustment is also subject to the provisions of Section 13 hereof, then only the provisions of Section 13 hereof shall apply and no adjustment shall be made pursuant to this Section 11.1.2.

11.1.3. In the event that there shall not be sufficient treasury or authorized but unissued (and unreserved) Common Stock to permit the exercise in full of the Rights in accordance with Section 11.1.2 and the Rights become so exercisable (and the Board of Directors of the Corporation has not determined to make the Rights exercisable solely into fractions of a share of Preferred Stock), notwithstanding any other provision of this Agreement, to the extent necessary and permitted by applicable law, each Right shall thereafter represent the right to receive, upon exercise thereof at the then current Purchase Price in accordance with the terms of this Agreement, (x) a number of (or fractions of) shares of Common Stock (up to the maximum number of shares of Common Stock that may permissibly be issued) and (y) one one-hundredth (1/100th) of a share of Preferred Stock or a number of, or fractions of, other equity securities of the Corporation (or, in the discretion of the Board of Directors of the Corporation, debt) that the Board of Directors of the Corporation has determined to have the same aggregate current market value (determined pursuant to Section 11.1.1 and Section 11.1.2 hereof, to the extent applicable)

16

as one share of Common Stock (such number of, or fractions of, shares of Preferred Stock, debt or other equity securities or debt of the Corporation being referred to as a "CAPITAL STOCK EQUIVALENT"), equal in the aggregate to the number of Adjustment Shares; PROVIDED, HOWEVER, if sufficient shares of Common Stock and/or Capital Stock Equivalents are unavailable, then the Corporation shall, to the extent permitted by applicable law, take all such action as may be necessary to authorize additional shares of Common Stock or Capital Stock Equivalents for issuance upon exercise of the Rights, including the calling of a meeting of stockholders; and PROVIDED, FURTHER, that if the Corporation is unable to cause sufficient shares of Common Stock and/or Capital Stock Equivalents to be available for issuance upon exercise in full of the Rights, then each Right shall thereafter represent the right to receive the Adjusted Number of Shares upon exercise at the Adjusted Purchase Price (as such terms are hereinafter defined). As used herein, the term "ADJUSTED NUMBER OF SHARES" shall be equal to that number of (or fractions of) shares of Common Stock (and/or Capital Stock Equivalents) equal to the product of (x) the number of Adjustment Shares and (y) a fraction, the numerator of which is the number of shares of Common Stock (and/or Capital Stock Equivalents) available for issuance upon exercise of the Rights and the denominator of which is the aggregate number of Adjustment Shares otherwise issuable upon exercise in full of all Rights (assuming there were a sufficient number of shares of Common Stock available) (such fraction being referred to as the "PRORATION FACTOR"). The "ADJUSTED PURCHASE PRICE" shall mean the product of the Purchase Price and the Proration Factor. The Board of Directors of the Corporation may, but shall not be required to, establish procedures to allocate the right to receive shares of Common Stock and Capital Stock Equivalents upon exercise of the Rights among holders of Rights.

11.2. In case the Corporation shall fix a record date for the issuance of rights (other than the Rights), options or warrants to all holders of Preferred Stock entitling them (for a period expiring within 45 calendar days after such record date) to subscribe for or purchase shares of Preferred Stock (or shares having the same rights, privileges and preferences as the Preferred Stock ("EQUIVALENT PREFERRED STOCK")) or securities convertible into Preferred Stock or Equivalent Preferred Stock at a price per share of Preferred Stock or Equivalent Preferred Stock (or having a conversion price per share, if a security convertible into shares of Preferred Stock or Equivalent Preferred Stock) less than the then current per share market price of the Preferred Stock (as determined pursuant to Section 11.4 hereof) on such record date, the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the number of shares of Preferred Stock outstanding on such record date plus the number of shares of Preferred Stock that the aggregate offering price of the total number of shares of Preferred Stock and/or Equivalent Preferred Stock so to be offered (and/or the aggregate initial conversion price of the convertible securities so to be offered) would purchase at such current per share market price, and the denominator of which shall be the number of shares of Preferred Stock outstanding on such record date plus the number of additional shares of Preferred Stock and/or Equivalent Preferred Stock to be offered for subscription or purchase (or into which the convertible securities so to be offered are initially convertible); PROVIDED, HOWEVER, that in no event shall the consideration to be paid upon the exercise of one Right be less than the aggregate par value, if any, of the shares of capital stock of the Corporation issuable upon exercise of one Right. In case

17

such subscription price may be paid in a consideration part or all of which shall be in a form other than cash, the value of such consideration shall be determined in good faith by the Board of Directors of the Corporation, whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of the Rights. Preferred Stock owned by or held for the account of the Corporation shall not be deemed outstanding for the purpose of any such computation. Such adjustment shall be made successively whenever such a record date is fixed; and in the event that such rights, options or warrants are not so issued, the Purchase Price shall be adjusted to be the Purchase Price that would then be in effect if such record date had not been fixed.

11.3. In case the Corporation shall fix a record date for the making of a distribution to all holders of the Preferred Stock (including any such distribution made in connection with a consolidation or merger in which the Corporation is the continuing or surviving corporation) of evidences of indebtedness or assets (other than a regular quarterly cash dividend or a dividend payable in Preferred Stock) or subscription rights or warrants (excluding those referred to in Section 11.2 hereof), the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the then current per share market price (as determined pursuant to Section 11.4 hereof) of the Preferred Stock on such record date, less the fair market value (as determined in good faith by the Board of Directors of the Corporation, whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of the Rights) of the portion of the assets or evidences of indebtedness so to be distributed or of such subscription rights or warrants applicable to one share of Preferred Stock, and the denominator of which shall be such current per share market price of the Preferred Stock; PROVIDED, HOWEVER, that in no event shall the consideration to be paid upon the exercise of one Right be less than the aggregate par value, if any, of the shares of capital stock of the Corporation to be issued upon exercise of one Right. Such adjustments shall be made successively whenever such a record date is fixed; and in the event that such distribution is not so made, the Purchase Price shall again be adjusted to be the Purchase Price that would then be in effect if such record date had not been fixed.

11.4. COMPUTATION OF "CURRENT PER SHARE MARKET PRICE."

11.4.1. For the purpose of any computation hereunder, the "current per share market price" of any security (a "Security" for the purpose of this Section 11.4.1) on any date shall be deemed to be the average of the daily closing prices per share of such Security for the thirty (30) consecutive Trading Days immediately prior to and not including such date; PROVIDED, HOWEVER, that in the event that the current per share market price of the Security is determined during a period following the announcement by the issuer of such Security of (A) a dividend or distribution on such Security payable in shares of such Security or securities convertible into such shares, or (B) any subdivision, combination or reclassification of such Security and prior to the expiration of thirty (30) Trading Days after the ex-dividend date for such dividend or distribution, or the record date for such subdivision, combination or reclassification,

18

then, and in each such case, the current per share market price shall be appropriately adjusted to reflect the current market price per share equivalent of such Security. The closing price for each day shall be the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the Security is not listed or admitted to trading on the New York Stock Exchange, as reported in the principal consolidated transaction reporting system with respect to securities listed on the principal national securities exchange on which the Security is listed or admitted to trading or, if the Security is not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by the National Association of Securities Dealers, Inc. Automated Quotations System ("NASDAQ") or such other system then in use, or, if on any such date the Security is not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Security selected by the Board of Directors of the Corporation. If on any such date no such market maker is making a market in the Security, the fair value of the Security on such date as determined in good faith by the Board of Directors of the Corporation shall be used. The term "TRADING DAY" shall mean a day on which the principal national securities exchange on which the Security is listed or admitted to trading is open for the transaction of business or, if the Security is not listed or admitted to trading on any national securities exchange, a Business Day.

11.4.2. For the purpose of any computation hereunder, the "current per share market price" of the Preferred Stock shall be determined in accordance with the method set forth in Section 11.4.1. If the shares of Preferred Stock are not publicly traded, the "current per share market price" of the Preferred Stock shall be conclusively deemed to be the current per share market price of the Common Stock as determined pursuant to Section
11.4.1 (appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date hereof), multiplied by 100. If neither the Common Stock nor the Preferred Stock are publicly held or so listed or traded, "current per share market price" shall mean, with respect to the Preferred Stock, the fair value per share as determined in good faith by the Board of Directors of the Corporation, whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of the Rights.

11.5. Anything herein to the contrary notwithstanding, no adjustment in the Purchase Price shall be required unless such adjustment would require an increase or decrease of at least 1% in the Purchase Price; PROVIDED, HOWEVER, that any adjustments that by reason of this Section 11.5 are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 11 shall be made to the nearest cent or to the nearest one one-hundredth (1/100th) of a share of Preferred Stock or of any other share or security as the case may be. Notwithstanding the first sentence of this Section 11.5, any adjustment required by this Section 11 shall be made no later than the earlier of (i) three (3) years from the date of the transaction that mandates such adjustment or (ii) the Final Expiration Date.

19

11.6. If as a result of an adjustment made pursuant to Section 11.1.2 or Section 13.1 hereof, the holder of any Right thereafter exercised shall become entitled to receive any shares of capital stock of the Corporation other than Preferred Stock, thereafter the number of other shares so receivable upon exercise of any Right shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Preferred Stock contained in Section 11.1 through 11.3, inclusive, and the provisions of Sections 7, 9, 10, 13 and 14 with respect to the Preferred Stock shall apply on like terms to any such other shares.

11.7. All Rights originally issued by the Corporation subsequent to any adjustment made to the Purchase Price hereunder shall evidence the right to purchase, at the adjusted Purchase Price, the number of one one-hundredths (1/100ths) of a share of Preferred Stock purchasable from time to time hereunder upon exercise of the Rights, all subject to further adjustment as provided herein.

11.8. The Corporation may elect on or after the date of any adjustment of the Purchase Price to adjust the number of Rights, in lieu of any adjustment in the number of one one-hundredths (1/100ths) of a share of Preferred Stock purchasable upon the exercise of a Right. Each of the Rights outstanding after such adjustment of the number of Rights shall be exercisable for the number of one one-hundredths (1/100ths) of a share of Preferred Stock for which a Right was exercisable immediately prior to such adjustment. Each Right held of record prior to such adjustment of the number of Rights shall become that number of Rights (calculated to the nearest one ten-thousandth) obtained by dividing the Purchase Price in effect immediately prior to adjustment of the Purchase Price by the Purchase Price in effect immediately after adjustment of the Purchase Price. The Corporation shall make a public announcement of its election to adjust the number of Rights, indicating the record date for the adjustment, and, if known at the time, the amount of the adjustment to be made, and shall deliver a copy of such public announcement to the Rights Agent. This record date may be the date on which the Purchase Price is adjusted or any day thereafter, but, if the Right Certificates have been issued, shall be at least ten (10) days later than the date of the public announcement. If Right Certificates have been issued, upon each adjustment of the number of Rights pursuant to this Section 11.8, the Corporation shall, as promptly as practicable, cause to be distributed to holders of record of Right Certificates on such record date Right Certificates evidencing, subject to Section 14 hereof, the additional Rights to which such holders shall be entitled as a result of such adjustment, or, at the option of the Corporation, shall cause to be distributed to such holders of record in substitution and replacement for the Right Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Corporation, new Right Certificates evidencing all the Rights to which such holders shall be entitled after such adjustment. Right Certificates so to be distributed shall be issued, executed and countersigned in the manner provided for herein and shall be registered in the names of the holders of record of Right Certificates on the record date specified in the public announcement.

20

11.9. Irrespective of any adjustment or change in the Purchase Price or the number of one one-hundredths (1/100ths) of a share of Preferred Stock issuable upon the exercise of the Rights, the Right Certificates theretofore and thereafter issued may continue to express the Purchase Price and the number of one one-hundredths (1/100ths) of a share of Preferred Stock that were expressed in the initial Right Certificates issued hereunder.

11.10. Before taking any action that would cause an adjustment reducing the Purchase Price below the then par value, if any, of the number of one one-hundredths (1/100ths) of a share of Preferred Stock, share of Common Stock or other securities issuable upon exercise of the Rights, the Corporation shall take any corporate action that may, in the opinion of its counsel, be necessary in order that the Corporation may validly and legally issue such number of fully paid and non-assessable one one-hundredths (1/100ths) of a share of Preferred Stock, share of Common Stock or other securities at such adjusted Purchase Price.

11.11. In any case in which this Section 11 shall require that an adjustment in the Purchase Price be made effective as of a record date for a specified event, the Corporation may elect to defer until the occurrence of such event the issuance to the holder of any Right exercised after such record date of the Preferred Stock, shares of Common Stock or other securities of the Corporation, if any, issuable upon such exercise over and above the Preferred Stock, shares of Common Stock or other securities of the Corporation, if any, issuable upon such exercise on the basis of the Purchase Price in effect prior to such adjustment; PROVIDED, HOWEVER, that the Corporation shall deliver to such holder a due bill or other appropriate instrument evidencing such holder's right to receive such additional shares upon the occurrence of the event requiring such adjustment and shall deliver to the Rights Agent a notice describing the terms of such due bill or other appropriate instrument.

11.12. Anything in this Section 11 to the contrary notwithstanding, the Corporation shall be entitled to make such reductions in the Purchase Price, in addition to those adjustments expressly required by this Section 11, as and to the extent that the Corporation in its sole discretion shall determine to be advisable in order that any (i) consolidation or subdivision of the Preferred Stock, (ii) issuance wholly for cash of Preferred Stock at less than the current market price, (iii) issuance wholly for cash of Preferred Stock or securities that by their terms are convertible into or exchangeable for Preferred Stock, (iv) stock dividends or
(v) issuance of rights, options or warrants referred to in this Section 11, hereafter made by the Corporation to holders of its Preferred Stock shall not be taxable to such holders.

11.13. The Corporation covenants and agrees that it shall not, at any time after the Distribution Date, (i) consolidate with any other Person (other than a Subsidiary of the Corporation in a transaction that does not violate Section 11.14 hereof), (ii) merge with or into any other Person (other than a Subsidiary of the Corporation in a transaction that does not violate Section 11.14 hereof), or (iii) sell or transfer (or permit any Subsidiary to sell or transfer), in one transaction, or a series of related transactions, assets or earning power aggregating more than

21

50% of the assets or earning power of the Corporation and its Subsidiaries (taken as a whole) to any other Person or Persons (other than the Corporation and/or any of its Subsidiaries in one or more transactions each of which does not violate Section 11.14 hereof), if (x) at the time of or immediately after such consolidation, merger, sale or transfer, there are any charter or bylaw provisions or any rights, warrants or other instruments or securities outstanding or agreements in effect or other actions taken that would materially diminish or otherwise eliminate the benefits intended to be afforded by the Rights or (y) prior to, simultaneously with or immediately after such consolidation, merger, sale or transfer, the stockholders of the Person who constitutes, or would constitute, the "Principal Party" for purposes of Section 13.1 hereof shall have received a distribution of Rights previously owned by such Person or any of its Affiliates and Associates. The Corporation shall not consummate any such consolidation, merger, sale or transfer unless prior thereto the Corporation and such other Person shall have executed and delivered to the Rights Agent a supplemental agreement evidencing compliance with this Section 11.13.

11.14. The Corporation covenants and agrees that, after the Distribution Date, it will not, except as permitted by Section 23 or Section 25.2 hereof, take (or permit any Subsidiary to take) any action the purpose of which is to, or if at the time such action is taken it is reasonably foreseeable that the effect of such action is to, materially diminish or otherwise eliminate the benefits intended to be afforded by the Rights.

11.15. The exercise of Rights under Section 11.1.2 shall only result in the loss of rights under Section 11.1.2 to the extent so exercised and shall not otherwise affect the rights represented by the Rights under this Agreement, including the rights represented by Section 13.

12. CERTIFICATE OF ADJUSTED PURCHASE PRICE OR NUMBER OF SHARES.

12.1. Whenever an adjustment is made as provided in Section 11 or
Section 13 hereof, the Corporation shall promptly (a) prepare a certificate setting forth such adjustment and a brief, reasonably detailed statement of the facts, computations and methodology accounting for such adjustment, (b) file with the Rights Agent and with each transfer agent for the Common Stock and the Preferred Stock a copy of such certificate and (c) mail a brief summary thereof to each holder of a Right Certificate in accordance with
Section 25.1 hereof. The Rights Agent shall be fully protected in relying on any such certificate and on any adjustment therein contained and shall have no duty with respect to, and shall not be deemed to have knowledge of, such adjustment unless and until it shall have received such certificate.

13. CONSOLIDATION, MERGER OR SALE OR TRANSFER OF ASSETS OR EARNING POWER.

13.1. In the event that, on or following the Shares Acquisition Date, directly or indirectly, (x) the Corporation shall consolidate with, or merge with and into, any Interested Stockholder or, if in such merger or consolidation all holders of shares of Common Stock are not

22

treated alike, any other Person, (y) the Corporation shall consolidate with, or merge with, any Interested Stockholder or, if in such merger or consolidation all holders of shares of Common Stock are not treated alike, any other Person, and the Corporation shall be the continuing or surviving corporation of such consolidation or merger (other than, in a case of any transaction described in (x) or (y), a merger or consolation that would result in all of the securities generally entitled to vote in the election of directors of the Corporation ("voting securities") outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into securities of the surviving entity) all of the voting securities of the Corporation or such voting surviving entity outstanding immediately after such merger or consolidation and the holders of such securities not having changed as a result of such merger or consolidation), or (z) the Corporation shall sell or otherwise transfer (or one or more of its Subsidiaries shall sell or otherwise transfer), in one transaction or a series of related transactions, assets or earning power aggregating more than 50% of the assets or earning power of the Corporation and its Subsidiaries (taken as a whole) to any Interested Stockholder or Stockholders or, if in such transaction all holders of Common Stock are not treated alike, any other Person (other than the Corporation or any Subsidiary of the Corporation in one or more transactions each of which does not violate Section 11.14 hereof), then, and in each such case (except as provided in Section 13.4 hereof), proper provision shall be made so that (i) each holder of a Right, except as provided in Section 7.6 hereof, shall thereafter have the right to receive, upon the exercise thereof at a price equal to the then current Purchase Price, in accordance with the terms of this Agreement and in lieu of Preferred Stock, such number of freely tradeable shares of Common Stock of the Principal Party, not subject to any liens, encumbrances, rights of first refusal or other adverse claims, as shall equal the result obtained by (A) multiplying the then current Purchase Price by the number of one one-hundredths (1/100ths) of a share of Preferred Stock for which a Right is then exercisable (without taking into account any adjustment previously made pursuant to Section 11.1.2) and dividing that product by (B) 50% of the then current per share market price of the Common Stock of such Principal Party (determined pursuant to Section 11.4 hereof) on the date of consummation of such Section 13 Event; (ii) such Principal Party shall thereafter be liable for, and shall assume, by virtue of such Section 13 Event, all the obligations and duties of the Corporation pursuant to this Agreement; (iii) the term "Corporation" shall thereafter be deemed to refer to such Principal Party, it being specifically intended that the provisions of Section 11 hereof shall apply only to such Principal Party following the first occurrence of a Section 13 Event; and (iv) such Principal Party shall take such steps (including, but not limited to, the reservation of a sufficient number of its shares of Common Stock) in connection with the consummation of any such transaction as may be necessary to assure that the provisions hereof shall thereafter be applicable, as nearly as reasonably may be, in relation to the shares of Common Stock thereafter deliverable upon the exercise of the Rights.

13.2. "PRINCIPAL PARTY" shall mean:

13.2.1. in the case of any transaction described in clause
(x) or (y) of the first sentence of Section 13.1, the Person that is the issuer of any securities into which shares of Common Stock of the Corporation are converted in such merger or consolidation, and if no

23

securities are so issued, the Person that is the other party to such merger or consolidation (including, if applicable, the Corporation if it is the surviving corporation); and

13.2.2. in the case of any transaction described in clause
(z) of the first sentence of Section 13.1, the Person that is the party receiving the greatest portion of the assets or earning power transferred pursuant to such transaction or transactions;

PROVIDED, HOWEVER, that in any of the foregoing cases, (1) if the Common Stock of such Person is not at such time and has not been continuously over the preceding twelve (12) month period registered under Section 12 of the Exchange Act, and such Person is a direct or indirect Subsidiary of another Person the shares of Common Stock of which are and have been so registered, "Principal Party" shall refer to such other Person; (2) in case such Person is a Subsidiary, directly or indirectly, of more than one Person, the shares of Common Stock of two or more of which are and have been so registered, "Principal Party" shall refer to whichever of such Persons is the issuer of the Common Stock having the greatest aggregate market value; and (3) in case such Person is owned, directly or indirectly, by a joint venture formed by two or more Persons that are not owned, directly or indirectly, by the same Person, the rules set forth in (1) and (2) above shall apply to each of the chains of ownership having an interest in such joint venture as if such party were a "Subsidiary" of both or all of such joint venturers and the Principal Parties in each such chain shall bear the obligations set forth in this
Section 13 in the same ratio as their direct or indirect interests in such Person bear to the total of such interests.

13.3. The Corporation shall not consummate any such consolidation, merger, sale or transfer unless the Principal Party shall have a sufficient number of its authorized shares of Common Stock that have not been issued or reserved for issuance to permit the exercise in full of the Rights in accordance with this Section 13 and unless prior thereto the Corporation and such Principal Party shall have executed and delivered to the Rights Agent a supplemental agreement providing for the terms set forth in Sections 13.1 and 13.2 and further providing that, as soon as practicable after the date of any consolidation, merger, sale or transfer mentioned in Section 13.1, the Principal Party at its own expense shall:

13.3.1. prepare and file a registration statement under the Act with respect to the Rights and the securities purchasable upon exercise of the Rights on an appropriate form, and will use its best efforts to cause such registration statement to (A) become effective as soon as practicable after such filing and (B) remain effective (with a prospectus at all times meeting the requirements of the Act) until the Final Expiration Date;

13.3.2. use its best efforts to qualify or register the Rights and the securities purchasable upon exercise of the Rights under the blue sky laws of such jurisdictions as may be necessary or appropriate; and

24

13.3.3. deliver to holders of the Rights historical financial statements for the Principal Party that comply in all respects with the requirements for registration on Form 10 under the Exchange Act.

The provisions of this Section 13 shall similarly apply to successive mergers or consolidations or sales or other transfers. The rights under this Section 13 shall be in addition to the rights to exercise Rights and adjustments under Section 11.1.2 and shall survive any exercise thereof.

13.4. Notwithstanding anything in this Agreement to the contrary, the foregoing provisions of this Section 13 shall not be applicable to a transaction described in clauses (x) and (y) of Section 13.1 if: (i) such transaction is consummated with a Person or Persons who acquired shares of Common Stock pursuant to a Permitted Offer (or a wholly owned Subsidiary of any such Person or Persons); (ii) the price per share of Common Stock offered in such transaction is not less than the price per share of Common Stock paid to all holders of shares of Common Stock whose shares were purchased pursuant to such Permitted Offer; and (iii) the form of consideration offered in such transaction is the same as the form of consideration paid pursuant to such Permitted Offer. Upon consummation of any such transaction contemplated by this Section 13.4, all Rights hereunder shall expire.

14. FRACTIONAL RIGHTS AND FRACTIONAL SHARES.

14.1. The Corporation shall not be required to issue fractions of Rights or to distribute Right Certificates that evidence fractional Rights. In lieu of such fractional Rights, there shall be paid to the registered holders of the Right Certificates with regard to which such fractional Rights would otherwise be issuable an amount in cash equal to the same fraction of the current market value of a whole Right. For the purposes of this Section 14.1, the current market value of a whole Right shall be the closing price of the Rights for the Trading Day immediately prior to the date on which such fractional Rights would have been otherwise issuable. The closing price for any day shall be the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the Rights are not listed or admitted to trading on the New York Stock Exchange, as reported in the principal consolidated transaction reporting system with respect to securities listed on the principal national securities exchange on which the Rights are listed or admitted to trading or, if the Rights are not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by NASDAQ or such other system then in use or, if on any such date the Rights are not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Rights selected by the Board of Directors of the Corporation. If on any such date no such market maker is making a market in the Rights, the fair value of the Rights on such date as determined in good faith by the Board of Directors of the Corporation shall be used.

25

14.2. The Corporation shall not be required to issue fractions of shares of Preferred Stock (other than fractions that are one one-hundredth (1/100th) or integral multiples of one one-hundredth (1/100th) of a share of Preferred Stock) upon exercise of the Rights or to distribute certificates that evidence fractional shares of Preferred Stock (other than fractions that are one one-hundredth (1/100th) or integral multiples of one one-hundredth (1/100th) of a share of Preferred Stock). Fractions of shares of Preferred Stock in integral multiples of one one-hundredth (1/100th) of a share of Preferred Stock may, at the election of the Corporation, be evidenced by depositary receipts, pursuant to an appropriate agreement between the Corporation and a depositary selected by it; PROVIDED that such agreement shall provide that the holders of such depositary receipts shall have the rights, privileges and preferences to which they are entitled as beneficial owners of the Preferred Stock represented by such depositary receipts. In lieu of fractional shares of Preferred Stock that are not one one-hundredth (1/100th) or integral multiples of one one-hundredth (1/100th) of a share of Preferred Stock, the Corporation shall pay to the registered holders of Right Certificates at the time such Rights are exercised as herein provided an amount in cash equal to the same fraction of the current market value of one share of Preferred Stock. For the purposes of this Section 14.2, the current market value of a share of Preferred Stock shall be the closing price of a share of Preferred Stock (as determined pursuant to Section 11.4.2 hereof) for the Trading Day immediately prior to the date of such exercise.

14.3. Following the occurrence of one of the transactions or events specified in Section 11 giving rise to the right to receive shares of Common Stock, Capital Stock Equivalents (other than Preferred Stock) or other securities upon the exercise of a Right, the Corporation shall not be required to issue fractions of shares or units of such shares of Common Stock, Capital Stock Equivalents or other securities upon exercise of the Rights or to distribute certificates that evidence fractions of such shares of Common Stock, Capital Stock Equivalents or other securities. In lieu of fractional shares or units of such shares of Common Stock, Capital Stock Equivalents or other securities, the Corporation may pay to the registered holders of Right Certificates at the time such Rights are exercised as herein provided an amount in cash equal to the same fraction of the current market value of a share or unit of such shares of Common Stock, Capital Stock Equivalents or other securities. For purposes of this Section 14.3, the current market value shall be determined in the manner set forth in Section 11.4 hereof for the Trading Day immediately prior to the date of such exercise and, if such Capital Stock Equivalent is not traded, each such Capital Stock Equivalent shall have the value of one one-hundredth (1/100th) of a share of Preferred Stock.

14.4. The holder of a Right by the acceptance of the Right expressly waives such holder's right to receive any fractional Rights or any fractional share upon exercise of a Right (except as provided above). The Rights Agent shall not be deemed to have knowledge of, and shall have no duty in respect of, the issuance of fractional Rights or fractional shares unless and until it shall have received instructions from the Corporation concerning the issuance of such fractional Rights or fractional shares.

26

15. RIGHTS OF ACTION.

15.1. All rights of action in respect of this Agreement, excepting the rights of action given to the Rights Agent under Section 18 hereof, are vested in the respective registered holders of the Right Certificates (and, prior to the Distribution Date, the registered holders of shares of the Common Stock); and any registered holder of any Right Certificate (or, prior to the Distribution Date, of shares of the Common Stock), without the consent of the Rights Agent or of the holder of any other Right Certificate (or, prior to the Distribution Date, of shares of the Common Stock), may, in such registered holder's own behalf and for such registered holder's own benefit, enforce, and may institute and maintain any suit, action or proceeding against the Corporation to enforce, or otherwise act in respect of, such registered holder's right to exercise the Rights evidenced by such Right Certificate in the manner provided in such Right Certificate and in this Agreement. Without limiting the foregoing or any remedies available to the holders of Rights, it is specifically acknowledged that the holders of Rights would not have an adequate remedy at law for any breach of this Agreement and will be entitled to specific performance of the obligations under, and injunctive relief against actual or threatened violations of the obligations of any Person subject to, this Agreement. Nothing in this Section 15 is intended to modify or limit the authority of the Board of Directors under
Section 25.3.

16. AGREEMENT OF RIGHT HOLDERS.

Every holder of a Right, by accepting the same, consents and agrees with the Corporation and the Rights Agent and with every other holder of a Right that:

16.1. prior to the Distribution Date, the Rights will be transferable only in connection with the transfer of the associated shares of Common Stock;

16.2. after the Distribution Date, the Right Certificates are transferable only on the registry books of the Rights Agent if surrendered at the office of the Rights Agent designated for such purpose, duly endorsed or accompanied by a proper instrument of transfer and with the appropriate form fully executed;

16.3. subject to Section 6 and Section 7.7 hereof, the Corporation and the Rights Agent may deem and treat the Person in whose name the Right Certificate (or, prior to the Distribution Date, the associated Common Stock certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of ownership or writing on the Right Certificate or the associated Common Stock certificate made by anyone other than the Corporation or the Rights Agent) for all purposes whatsoever, and neither the Corporation nor the Rights Agent, subject to the last sentence of Section 7.6 hereof, shall be required to be affected by any notice to the contrary; and

27

16.4. notwithstanding anything in this Agreement to the contrary, neither the Corporation nor the Rights Agent shall have any liability to any holder of a Right or a beneficial interest in a Right or other Person as a result of its inability to perform any of its obligations under this Agreement by reason of any preliminary or permanent injunction or other order, decree, judgment or ruling (whether interlocutory or final) issued by a court of competent jurisdiction or by a governmental, regulatory or administrative agency or commission, or any statute, rule, regulation or executive order promulgated or enacted by any governmental authority, prohibiting or otherwise restraining performance of such obligation; PROVIDED, HOWEVER, that the Corporation must use its best efforts to have any such order, decree, judgment or ruling lifted or otherwise overturned as soon as practicable.

17. RIGHT CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDEr.

No holder, as such, of any Right Certificate shall be entitled to vote, receive dividends or be deemed for any purpose the holder of shares of the Preferred Stock or any other securities of the Corporation that may at any time be issuable on the exercise of the Rights represented thereby, nor shall anything contained herein or in any Right Certificate be construed to confer upon the holder of any Right Certificate, as such, any of the rights of a stockholder of the Corporation or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting stockholders (except as provided in Section 24 hereof), or to receive dividends or other distributions or to exercise any preemptive or subscription rights, or otherwise, until the Right or Rights evidenced by such Right Certificate shall have been exercised in accordance with the provisions hereof.

18. CONCERNING THE RIGHTS AGENT.

18.1. The Corporation agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and other disbursements incurred in the administration, preparation, delivery, amendment and execution of this Agreement and the exercise and performance of its duties hereunder. The Corporation also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability, damage, judgment, fine, penalty, claim, demand, settlement, cost or expense incurred without gross negligence, bad faith or willful misconduct on the part of the Rights Agent, for any action taken, suffered or omitted by the Rights Agent in connection with the acceptance and administration of this Agreement, including without limitation the costs and expenses of defending against any claim of liability in the premises. The indemnity provided for herein shall survive the expiration of the Rights and the termination of this Agreement.

18.2. The Rights Agent shall be authorized and protected and shall incur no liability for, or in respect of, any action taken, suffered or omitted by it in connection with the acceptance and administration of this Agreement in reliance upon any Right Certificate or

28

certificate for shares of Common Stock or for other securities of the Corporation, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, statement or other paper or document believed by it to be genuine and to be signed, executed and, where necessary, verified or acknowledged, by the proper Person or Persons. The Rights Agent shall not be deemed to have knowledge of, and shall have no duty in respect of, any fact contained in such Right Certificate or certificate for shares of Common Stock or for other securities of the Corporation, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, statement or other paper or document unless and until it shall have received the same.

18.3. Anything in this Agreement to the contrary notwithstanding, in no event shall the Rights Agent be liable for special, indirect, incidental or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Rights Agent has been advised of the likelihood of such loss or damage and regardless of the form of the action.

19. MERGER OR CONSOLIDATION OR CHANGE OF NAME OF RIGHTS AGENT.

19.1. Any Person into which the Rights Agent or any successor Rights Agent may be merged or with which it may be consolidated, or any Person resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any Person succeeding to the stock transfer or all or substantially all of the shareholder services business of the Rights Agent or any successor Rights Agent, shall be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto, PROVIDED that such Person would be eligible for appointment as a successor Rights Agent under the provisions of Section 21 hereof.

19.2. In case at any time the name of the Rights Agent shall be changed and at such time any of the Right Certificates shall have been countersigned but not delivered, the Rights Agent may adopt the countersignature under its prior name and deliver Right Certificates so countersigned; and in case at that time any of the Right Certificates shall not have been countersigned, the Rights Agent may countersign such Right Certificates either in its prior name or in its changed name; and in all such cases such Right Certificates shall have the full force provided in the Right Certificates and in this Agreement.

20. DUTIES OF RIGHTS AGENT.

20.1. The Rights Agent undertakes those duties and obligations, and only the duties and obligations, expressly imposed by this Agreement (and no implied duties or obligations) upon the following terms and conditions, by all of which the Corporation and the holders of Right Certificates, by their acceptance thereof, shall be bound.

29

20.2. The Rights Agent may consult with legal counsel (who may be legal counsel for the Corporation), and the advice or opinion of such counsel shall be full and complete authorization and protection to the Rights Agent, and the Rights Agent shall incur no liability for or in respect of any action taken, suffered or omitted by it in good faith and in accordance with such advice or opinion.

20.3. Whenever in the performance of its duties under this Agreement the Rights Agent shall deem it necessary or desirable that any fact or matter (including, without limitation, the identity of an Acquiring Person and the determination of the current market price of any security) be proved or established by the Corporation prior to taking, suffering or omitting any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed by any one of the Chairman of the Board, the Chief Executive Officer, the President, any Vice President, the Treasurer or the Secretary of the Corporation and delivered to the Rights Agent; and such certificate shall be full authorization and protection to the Rights Agent and the Rights Agent shall incur no liability for or in respect of any action taken, suffered or omitted in good faith by it under the provisions of this Agreement in reliance upon such certificate.

20.4. The Rights Agent shall be liable hereunder only for its own gross negligence, bad faith or willful misconduct.

20.5. The Rights Agent shall not be liable for, or by reason of, any of the statements of fact or recitals contained in this Agreement or in the Right Certificates (except its countersignature on such Right Certificates) or be required to verify the same, but all such statements and recitals are and shall be deemed to have been made by the Corporation only.

20.6. The Rights Agent shall not be under any liability or responsibility in respect of the validity of this Agreement or the execution and delivery hereof (except the due execution hereof by the Rights Agent) or in respect of the validity or execution of any Right Certificate (except its countersignature thereof); nor shall it be responsible for any breach by the Corporation of any covenant or condition contained in this Agreement or in any Rights Certificate; nor shall it be responsible for any change in the exercisability of the Rights (including the Rights becoming null and void pursuant to Section 7.6 hereof) or any adjustment required under the provisions of Section 11, Section 13 or Section 26 hereof or responsible for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment (except with respect to the exercise of Rights evidenced by Right Certificates after receipt of the certificate described in Section 12 hereof); nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Preferred Stock or shares of Common Stock to be issued pursuant to this Agreement or any Right Certificate or as to whether any Preferred Stock or shares of Common Stock will, when issued, be validly authorized and issued, fully paid and non-assessable.

30

20.7. The Corporation agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Rights Agent for the carrying out or performing by the Rights Agent of the provisions of this Agreement.

20.8. The Rights Agent is hereby authorized and directed to accept instructions with respect to the performance of its duties hereunder from any one of the Chairman of the Board, the Chief Executive Officer, the President, any Vice President, the Treasurer or the Secretary of the Corporation, and to apply to such officers for advice or instructions in connection with its duties, and such instructions shall be full authorization and protection of the Rights Agent and the Rights Agent shall incur no liability for or in respect of any action taken, suffered or omitted by it in good faith or lack of action in accordance with instructions of any such officer or for any delay in acting while waiting for those instructions. The Rights Agent shall incur no liability for or in respect of its reliance upon the most recent instructions received by any such officer. Any application by the Rights Agent for written instructions from the Corporation may, at the option of the Rights Agent, set forth in writing any action proposed to be taken or omitted by the Rights Agent under this Agreement and the date on or after which such action shall be taken or suffered such omission shall be effective. The Rights Agent shall not be liable for any action taken or suffered by, or omission of, the Rights Agent in accordance with a proposal included in any such application on or after the date specified in such application (which date shall not be less than five (5) Business Days after the date any officer of the Corporation actually receives such application, unless any such officer shall have consented in writing to an earlier date) unless, prior to taking any such action (or the effective date in the case of an omission), the Rights Agent shall have received written instruction in response to such application specifying the action to be taken, suffered or omitted.

20.9. The Rights Agent and any stockholder, affiliate, director, officer or employee of the Rights Agent may buy, sell or deal in any of the Rights or other securities of the Corporation or become pecuniarily interested in any transaction in which the Corporation may be interested, or contract with or lend money to the Corporation or otherwise act as fully and freely as though it were not Rights Agent under this Agreement. Nothing herein shall preclude the Rights Agent from acting in any other capacity for the Corporation or for any other Person or legal entity.

20.10. The Rights Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorneys or agents, and the Rights Agent shall not be answerable or accountable for any act, default, negligence or misconduct of any such attorneys or agents or for any loss to the Corporation or any other Person resulting from any such act, default, negligence or misconduct, absent gross negligence, bad faith or willful misconduct in the selection and continued employment thereof.

31

20.11. No provision of this Agreement shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of its rights if it believes that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it.

20.12. If, with respect to any Rights Certificate surrendered to the Rights Agent for exercise or transfer, the certificate attached to the form of assignment or form of election to purchase, as the case may be, has not been completed, the Rights Agent shall not take any further action with respect to such requested exercise or transfer without first consulting with the Corporation.

21. CHANGE OF RIGHTS AGENT.

The Rights Agent or any successor Rights Agent may resign and be discharged from its duties under this Agreement upon thirty (30) days' notice in writing mailed to the Corporation and to each transfer agent of the Common Stock or Preferred Stock by registered or certified mail, and to the holders of the Right Certificates by first-class mail. The Corporation may remove the Rights Agent or any successor Rights Agent upon sixty (60) days' notice in writing, mailed to the Rights Agent or successor Rights Agent, as the case may be, and to each transfer agent of the Common Stock or Preferred Stock by registered or certified mail, and to holders of the Right Certificates by first-class mail. If the Rights Agent shall resign or be removed or shall otherwise become incapable of acting, the Corporation shall appoint a successor to the Rights Agent. If the Corporation shall fail to make such appointment within a period of sixty (60) days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent or by the holder of a Right Certificate (who shall, with such notice, submit his Right Certificate for inspection by the Corporation), then the registered holder of any Right Certificate may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Corporation or by such a court, shall be a Person organized and doing business under the laws of the United States or of any of the States of New York, New Jersey or California (or of any other state of the United States so long as such Person is authorized to do business in any of the States of New York, New Jersey or California), in good standing, having an office in any of such States, which is subject to supervision or examination by federal or state authority and which (or the parent corporation of which) has at the time of its appointment as Rights Agent a combined capital and surplus of at least $50,000,000. After appointment, the successor Rights Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed; but the predecessor Rights Agent shall deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. In case at the time such successor Rights Agent shall succeed to the agency created by this Agreement, any of the Right Certificates shall have been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of a predecessor Rights Agent and deliver such Right Certificates so countersigned; and in

32

case at that time any of the Right Certificates shall not have been countersigned, any successor Rights Agent may countersign such Right Certificates either in the name of the predecessor or in the name of the successor Rights Agent; and in all such cases such Right Certificates shall have the full force provided in the Right Certificates and in this Agreement. Not later than the effective date of any such appointment, the Corporation shall file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Stock or Preferred Stock, and mail a notice thereof in writing to the registered holders of the Right Certificates. Failure to give any notice provided for in this Section 21, however, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of the successor Rights Agent, as the case may be.

22. ISSUANCE OF NEW RIGHT CERTIFICATES.

22.1. Notwithstanding any of the provisions of this Agreement or of the Rights to the contrary, the Corporation may, at its option, issue new Right Certificates evidencing Rights in such form as may be approved by its Board of Directors to reflect any adjustment or change in the Purchase Price and the number or kind or class of shares or other securities or property purchasable under the Right Certificates made in accordance with the provisions of this Agreement.

22.2. In connection with the issuance or sale of Common Stock following the Distribution Date and prior to the earlier of the Redemption Date and the Final Expiration Date, the Corporation (a) shall with respect to shares of Common Stock so issued or sold pursuant to the exercise of stock options or under any employee plan or arrangement, or upon the exercise, conversion or exchange of securities, notes or debentures issued by the Corporation, and (b) may in any other case, if deemed necessary or appropriate by the Board of Directors of the Corporation, issue Right Certificates representing the appropriate number of Rights in connection with such issuance or sale; PROVIDED, HOWEVER, that (i) the Corporation shall not be obligated to issue any such Right Certificates if, and to the extent that, the Corporation shall be advised by counsel that such issuance would create a significant risk of material adverse tax consequences to the Corporation or the Person to whom such Right Certificate would be issued, and (ii) no Right Certificate shall be issued if, and to the extent that, appropriate adjustment shall otherwise have been made in lieu of the issuance thereof.

23. REDEMPTION AND TERMINATION.

23.1. REDEMPTION

23.1.1. The Board of Directors of the Corporation may, at its option, redeem all but not less than all of the then outstanding Rights at a redemption price of $.001 per Right, as such amount may be appropriately adjusted to reflect any stock split, stock dividend or

33

similar transaction occurring after the date hereof (such redemption price being hereinafter referred to as the "REDEMPTION PRICE"), at any time prior to the earlier of the occurrence of a Section 11.1.2 Event or the Final Expiration Date. The Corporation may, at its option, pay the Redemption Price either in shares of Common Stock (based on the current per share market price of the Common Stock at the time of redemption) or cash; PROVIDED that if the Corporation elects to pay the Redemption Price in shares of Common Stock, the Corporation shall not be required to issue any fractional shares of Common Stock and the number of shares of Common Stock issuable to each holder of Rights shall be rounded down to the next whole share.

23.1.2. In addition, the Board of Directors of the Corporation may, at its option, at any time following the occurrence of a
Section 11.1.2 Event and the expiration of any period during which the holder of Rights may exercise the Rights under Section 11.1.2 but prior to any
Section 13 Event redeem all but not less than all of the then outstanding Rights at the Redemption Price (x) in connection with any merger, consolidation or sale or other transfer (in one transaction or in a series of related transactions) of assets or earning power aggregating 50% or more of the earning power of the Corporation and its Subsidiaries (taken as a whole) in which all holders of shares of Common Stock are treated alike and not involving (other than as a holder of shares of Common Stock being treated like all other such holders) an Interested Stockholder or (y) (i) if and for so long as the Acquiring Person is not thereafter the Beneficial Owner of 15% or more of the Common Stock, and (ii) at the time of redemption no other Persons are Acquiring Persons.

23.2. In the case of a redemption permitted under Section 23.1.1, immediately upon the date for redemption set forth in (or determined in the manner specified in) a resolution of the Board of Directors of the Corporation ordering the redemption of the Rights, and without any further action and without any notice, the right to exercise the Rights will terminate and the only right thereafter of the holders of Rights shall be to receive the Redemption Price for each Right so held. In the case of a redemption permitted only under Section 23.1.2, the right to exercise the Rights will terminate and represent only the right to receive the Redemption Price upon the later of ten (10) Business Days following the giving of such notice or the expiration of any period during which the Rights may be exercised under Section 11.1.2. The Corporation shall promptly give public notice of any such redemption; PROVIDED, HOWEVER, that the failure to give, or any defect in, any such notice shall not affect the validity of such redemption. Within ten (10) days after such date for redemption set forth in a resolution of the Board of Directors of the Corporation ordering the redemption of the Rights, the Corporation shall mail a notice of redemption to the Rights Agent and all the holders of the then outstanding Rights at (in the case of notice to holders) their addresses as they appear upon the registry books of the Rights Agent or, prior to the Distribution Date, on the registry books of the transfer agent for the Common Stock. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of redemption will state the method by which the payment of the Redemption Price will be made. Neither the Corporation nor any of its Affiliates or Associates may redeem, acquire or purchase for value any Rights at

34

any time in any manner other than as specifically set forth in this Section 23 and other than in connection with the purchase of shares of Common Stock prior to the Distribution Date.

23.3. The Corporation may, at its option, discharge all of its obligations with respect to the Rights by (i) issuing a press release announcing the manner of redemption of the Rights in accordance with this Agreement and (ii) mailing payment of the Redemption Price to the registered holders of the Rights at their addresses as they appear on the registry books of the Rights Agent or, prior to the Distribution Date, on the registry books of the Transfer Agent of the Common Stock, and upon such action, all outstanding Rights and Right Certificates shall be null and void without any further action by the Corporation.

24. NOTICE OF CERTAIN EVENTS.

24.1. In case the Corporation shall propose (i) to pay any dividend payable in stock of any class to the holders of its Preferred Stock or to make any other distribution to the holders of its Preferred Stock (other than a regular quarterly cash dividend), (ii) to offer to the holders of its Preferred Stock rights or warrants to subscribe for or to purchase any additional Preferred Stock or shares of stock of any class or any other securities, rights or options, (iii) to effect any reclassification of its Preferred Stock (other than a reclassification involving only the subdivision of outstanding Preferred Stock), (iv) to effect any consolidation or merger into or with any other Person (other than a Subsidiary of the Corporation in a transaction which does not violate Section 11.14 hereof), or to effect any sale or other transfer (or to permit one or more of its Subsidiaries to effect any sale or other transfer) in one or more transactions, of 50% or more of the assets or earning power of the Corporation and its Subsidiaries (taken as a whole) to any other Person or Persons (other than the Corporation and/or any of its Subsidiaries in one or more transactions each of which does not violate Section 11.14 hereof), or (v) to effect the liquidation, dissolution or winding up of the Corporation, then, in each such case, the Corporation shall give the Rights Agent and to each holder of a Right Certificate, in accordance with Section 25 hereof, a notice of such proposed action which shall specify the record date for the purposes of such stock dividend or distribution of rights or warrants, or the date on which such reclassification, consolidation, merger, sale, transfer, liquidation, dissolution or winding up is to take place and the date of participation therein by the holders of the Preferred Stock, if any such date is to be fixed, and such notice shall be so given in the case of any action covered by clause (i) or (ii) above at least twenty (20) days prior to the record date for determining holders of the Preferred Stock for purposes of such action, and in the case of any such other action, at least twenty (20) days prior to the date of the taking of such proposed action or the date of participation therein by the holders of the Preferred Stock, whichever shall be the earlier.

24.2. In case of a Section 11.1.2 Event, then (i) the Corporation shall as soon as practicable thereafter give to each holder of a Right Certificate, in accordance with Section 25.1.3 hereof, a notice of the occurrence of such event, which notice shall describe such event and the consequences of such event to holders of Rights under Section 11.1.2 hereof, and

35

(ii) all references in the preceding Section 24.1 to Preferred Stock shall be deemed thereafter to refer also to shares of Common Stock and/or, if appropriate, other securities of the Corporation.

All such actions, calculations, interpretations and determinations (including, for purposes of clause (y) below, all omissions with respect to the foregoing) which are done or made by the Board in good faith, shall (x) be final, conclusive and binding on the Corporation, the Rights Agent, the holders of the Right Certificates and all other Persons, and (y) not subject the Board to any liability to the holders of the Right Certificates.

25.5. BENEFITS OF THIS AGREEMENT.

25.7. GOVERNING LAW. This Agreement, each Right and each Right Certificate issued hereunder shall be deemed to be a contract made under the laws of the State of Washington and for all purposes shall be governed by and construed in accordance with the laws of such State applicable to contracts to be made and performed entirely within such State; except that all provisions regarding the rights, duties and obligations of the Rights Agent shall be governed and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed entirely within such State.

25.8. COUNTERPARTS. This Agreement may be executed in any number of counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.

25.9. DESCRIPTIVE HEADINGS. Descriptive headings of the several sections of this Agreement are inserted for convenience only and shall not control or affect the meaning or construction of any of the provisions hereof.

26. EXCHANGE.

26.1. Notwithstanding any other provision hereof, the Board of Directors of the Corporation may, at its option, at any time after any Person becomes an Acquiring Person, exchange all or part of the then outstanding and exercisable Rights (which shall not include Rights that have become null and void pursuant to the provisions of Section 7.6 hereof) for shares of Common Stock of the Corporation at an exchange ratio determined by dividing the then-applicable exercise price of the Rights determined under Section 7.2 by the "current per share market price" as defined in Section 11.4.1 (such exchange ratio being hereinafter referred to as the "EXCHANGE RATIO"). Notwithstanding the foregoing, the Corporation's Board of Directors shall not be empowered to effect such exchange at any time after any Person (other than the Corporation, any Subsidiary of the Corporation, any employee benefit plan of the Corporation or any such Subsidiary, or any Person organized, appointed or established by the Corporation for or pursuant to the terms of any such plan or any trustee, administrator or

38

fiduciary of such a plan), together with all Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or more of the Common Stock then outstanding.

26.2. Immediately upon the action of the Board of Directors of the Corporation ordering the exchange of any Rights pursuant to Section 26.1 and without any further action and without any notice, the right to exercise such rights shall terminate and the only right thereafter of the holder of such Rights (other than a holder of Rights that have become null and void pursuant to the provisions of Section 7.6 hereof) shall be to receive that number of shares of Common Stock equal to the number of such Rights held by such holder multiplied by the Exchange Ratio. The Corporation shall promptly give public notice, and shall promptly give notice to the Rights Agent, of any such exchange; PROVIDED, HOWEVER, that the failure to give, or any defect in, such notice shall not affect the validity of such exchange. The Corporation promptly shall mail a notice of any such exchange to all of the holders of such Rights at their last addresses as they appear upon the registry books of the Rights Agent. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of exchange shall state the method by which the exchange of the Common Stock for Rights will be effected and, in the event of any partial exchange, the number of Rights which will be exchanged. Any partial exchange shall be effected pro rata based on the number of Rights (other than Rights which have become void pursuant to the provisions of Section 7.6) held by each holder of Rights.

26.3. In the event that there shall not be sufficient shares of Common Stock issued but not outstanding or authorized but unissued to permit any exchange of Rights as contemplated in accordance with this Section 26, the Corporation shall take all such action as may be necessary to authorize additional shares of Common Stock or Preferred Stock for issuance upon exchange of the Rights.

DATA I/O CORPORATION

This certifies that __________, or registered assigns, is the registered owner of the number of Rights set forth above, each of which entitles the owner thereof, subject to the terms, provisions and conditions of the Rights Agreement, dated as of April 4, 1998 (the "Rights Agreement"), between Data I/O Corporation, a Washington corporation (the "Corporation"), and ChaseMellon Shareholder Services, L.L.C., a New Jersey limited liability company, (the "Rights Agent") to purchase from the Corporation at any time after the Distribution Date (as such term is defined in the Rights Agreement) and prior to 5:00 P.M., Washington time, on April 4, 2008, unless the Rights evidenced hereby shall have been previously redeemed by the Corporation, at the principal office or offices of the Rights Agent designated for such purpose, or at the office of its successor as Rights Agent, one one-hundredth (1/100th) of a fully paid non-assessable share of Series A Junior Participating Preferred Stock (the "Preferred Stock") of the Corporation, at a purchase price of $30 per one one-hundredth (1/100th) of a share of Preferred Stock (the "Purchase Price"), upon presentation and surrender of this Right Certificate with the Form of Election to Purchase duly executed. The number of Rights evidenced by this Right Certificate (and the number of one one-hundredths (1/100ths) of a share of Preferred Stock that may be purchased upon exercise hereof) set forth above, and the Purchase Price set forth above, are the number and Purchase Price as of _______________, based on the Preferred Stock as constituted at such date.

Upon the occurrence of a Section 11.1.2 Event (as such term is defined in the Rights Agreement), if the Rights evidenced by this Right Certificate are beneficially owned by (i) an Acquiring Person or an Affiliate or Associate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or of any Affiliate or Associate thereof) who becomes a transferee after the Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person (or of an Affiliate or Associate thereof) who becomes a transferee prior to or concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person (or from any Affiliate or Associate thereof) to holders of equity interests in such Acquiring Person or to any Person with whom the Acquiring Person has a continuing agreement, arrangement


or understanding regarding the transferred Rights or (B) a transfer that the Board of Directors of the Corporation has determined is part of a plan, arrangement or understanding that has as a primary purpose or effect the avoidance of Section 7.6 of the Rights Agreement, shall become null and void without any further action and no holder hereof shall have any rights whatsoever with respect to such Rights, whether under any provision of the Rights Agreement or otherwise.

As provided in the Rights Agreement, the Purchase Price and the number of one one-hundredths (1/100ths) of a share of Preferred Stock or other securities that may be purchased upon the exercise of the Rights evidenced by this Right Certificate are subject to modification and adjustment upon the happening of certain events, including Triggering Events (as such term is defined in the Rights Agreement).

This Right Certificate is subject to all of the terms, covenants and restrictions of the Rights Agreement, which terms, covenants and restrictions are hereby incorporated herein by reference and made a part hereof and to which Rights Agreement reference is hereby made for a full description of the rights, limitations of rights, obligations, duties and immunities hereunder of the Rights Agent, the Corporation and the holders of the Right Certificates, which limitations of rights include the temporary suspension of the exercisability of such Rights under the specific circumstances set forth in the Rights Agreement. Copies of the Rights Agreement are on file at the principal executive offices of the Corporation and the office of the Rights Agent.

EXHIBIT B

DATA I/0 CORPORATION
10525 Willows Road N.E.
Redmond, Washington 98052

SUMMARY OF RIGHTS TO PURCHASE
SERIES A JUNIOR PARTICIPATING PREFERRED SHARES

On March 12, 1998, the Board of Directors (the "Board") of Data I/0 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"), 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/ (the "Preferred Stock"), of the Corporation 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.

Initially, the Rights will be attached to all 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 earliest 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 (except pursuant to a Permitted Offer, as hereinafter defined) 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) (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."

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 such notation or a copy of this Summary of Rights being attached thereto, 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 the shares of 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 exercise 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.

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

2

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 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.

Preferred Stock purchasable upon exercise of the Rights will not be redeemable. Each share of Preferred Stock will be entitled to a minimum preferential quarterly dividend payment of $1.00 per share but, if greater, will be entitled to an aggregate dividend per share of 100 times the dividend declared per share of Common Stock. In the event of liquidation, the holders of shares of the Preferred Stock will be entitled to a minimum preferential liquidation payment per share in an amount equal to $100 plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment (the "Series A Junior Participating Liquidation Preference"); thereafter, and after the holders of shares of the Common Stock receive a liquidation payment of an amount equal to the quotient obtained by dividing the Series A Junior Participating Liquidation Preference by 100 (subject to certain adjustments for stock splits, stock dividends and recapitalizations with respect to the Common Stock), the holders of shares of the Preferred Stock and the holders of the Common Stock will share the remaining assets in the ratio of 100 to 1 (as adjusted) for each share of Preferred Stock and Common Stock so held, respectively. Finally, in the event of any merger, consolidation or other transaction in which shares of Common Stock are exchanged, each share of Preferred Stock will be entitled to receive 100 times the amount received per share of Common Stock. These rights are protected by customary antidilution provisions. In the event that the amount of accrued and unpaid dividends on the Preferred Stock is equivalent to six full quarterly dividends or more, the holders of shares of the Preferred Stock shall have the right, voting as a class, to elect two directors in addition to the directors elected by the holders of shares of the Common Stock until all cumulative dividends on the Preferred Stock have been paid or set apart for payment through the last quarterly dividend payment date. No fractional shares of Preferred Stock will be issued (other than fractions which are one one-hundredth (1/100th) or integral multiples of one one-hundredth (1/100th) of a share of Preferred Stock, which may, at the election of the Corporation, be evidenced by depositary receipts) and in lieu thereof, an adjustment in cash will be made

3

based on the market price of the Preferred Stock on the last trading day prior to the date of exercise.

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 $0.001 per Right (the "Redemption Price"), which redemption shall be effective upon the action of the Board. Additionally, 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 of Directors of the Corporation prior to the Distribution Date. After the Distribution Date, the provisions of the Rights Agreement may be amended by the Board of Directors of the Corporation 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.

A copy of the Rights Agreement has been filed with the Securities and Exchange Commission as an Exhibit to a Registration Statement on Form 8-A. A copy of the Rights Agreement is available free of charge from the Corporation. 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 soon as practicable after the Distribution Date, the Rights Agent will send by first-class, insured, postage prepaid mail, to each record holder of the Common Stock as of the close of business on the Distribution Date, at the address of such holder shown on the records of the Company, one or more rights certificates, in substantially the form of Exhibit a hereto (the "Rights Certificates"), evidencing one Right for each share of Common Stock so held, subject to adjustment as provided herein.

As of and after the Distribution Date, the Rights will be evidenced solely by such Rights Certificates.

(b) As promptly as practicable following the Record Date, the Company will send a copy of a Summary of Rights to Purchase Preferred Stock, in substantially the form attached hereto as Exhibit C, by first-class postage prepaid mail, to each record holder of the Common Stock as of the close of business on the Record Date, at the address of such holder shown on the records of the Company. With respect to certificates for the Common Stock outstanding as of the Record Date, until the Distribution Date, the Rights will be evidenced by such certificates for the Common Stock and the registered holders of the Common Stock shall also be the registered holders of the associated Rights. Until the earlier of the Distribution Date or the Expiration Date, the transfer of any certificates representing shares of Common Stock in respect of which Rights have been issued shall also constitute the transfer of the Rights associated with such shares of Common Stock.

(c) Rights shall be issued in respect of all shares of Common Stock which are issued after the Record Date but prior to the earlier of the Distribution Date or the Expiration Date. Certificates representing such shares of Common Stock shall also be deemed to be certificates for Rights, and shall bear the following legend:

This certificate also evidences and entitles the holder hereof to certain Rights as set forth in the Rights Agreement between Data I/O Corporation, (the "Company") and The First Jersey National Bank (the "Rights Agent") dated as of

7

March 31, 1988, as amended, (the "Rights Agreement"), the terms of which are hereby incorporated herein by reference and a copy of which is on file at the principal offices of the Rights Agent. Under certain circumstances, as set forth in the Rights Agreement, such Rights will be evidenced by separate certificates and will no longer be evidenced by this certificate. The Rights Agent will mail to the holder of this certificate a copy of the Rights Agreement, as in effect .on the date of mailing, without charge promptly after receipt of a written request therefor. Under certain circumstances set forth in the Rights Agreement, Rights issued to, or held by, any Person who is, was or becomes an Acquiring Person, an Adverse Person or any Affiliate or Associate thereof (as such terms are defined in the .Rights Agreement), whether currently held by or on behalf of such Person or by any subsequent holder, may become null and void.

With respect to such certificates containing the foregoing legend, until the earlier of (i) the Distribution Date or (ii) the Expiration Date, the Rights associated with the Common Stock represented by such certificates shall be evidenced by such certificates alone and registered holders of Common Stock shall also be the registered holders of the Associated Rights, and the transfer of any of such certificates shall also constitute the transfer of the Rights associated with the Common Stock represented by such certificates.

Section 4. FORM OF RIGHTS CERTIFICATES.

(a) The Rights Certificates (and the Form of Election To Purchase and of Assignment to be printed on the reverse thereof) shall each be substantially in the form set forth in Exhibit B hereto and may have such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Company may deem appropriate and as are not inconsistent with the provisions of this Agreement or as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange on which the Rights may from time to time be listed, or to conform to usage. Subject to the provisions of Section 11 and Section 22 hereof, the Rights Certificates, whenever distributed, shall be dated as of the Record Date and on their face shall entitle the holders thereof to purchase such number of one one-hundredth of a share of Preferred Stock as shall be set forth therein at the price set forth therein (such exercise price per one one-hundredth of a share, the "Purchase Price"), but the amount and type of securities purchasable upon the exercise of each Right and the Purchase Price thereof shall be subject to adjustment as provided herein.

(b) Any Rights Certificates issued pursuant to Section 3(a) or
Section 22 hereof that represent Rights beneficially owned by: (i) an Acquiring Person or any Associate or Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee after the Acquiring Person

8

becomes such, or (iii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee prior to or concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person to holders of equity interests in such Acquiring Person or to any Persons with whom such Acquiring Person has any continuing agreement, arrangement or understanding regarding the transferred Rights or (B) a transfer which the Board of Directors of the Company has determined is part of a plan, arrangement or understanding which has as a primary purpose or effect avoidance of Section 7(e) hereof, and any Rights Certificate issued pursuant to Section 6 or Section 11 hereof upon transfer, exchange, replacement or adjustment of any other Rights Certificate referred to in this sentence, shall contain (to the extent feasible) the following legend:

The Rights represented by this Rights Certificates are or were beneficially owned by a Person who was or became an Acquiring Person or an Affiliate or Associate of an Acquiring Person (as such terms are defined in the Company's Rights Agreement, as amended). Accordingly, this Rights Certificate and the Rights represented hereby may become null and void in the circumstances specified in Section 7(e) of such Agreement.

Section 5. COUNTERSIGNATURE AND REGISTRATION.

(a) The Rights Certificates shall be executed on behalf of the Company by its Chief Executive Officer, its President or any Vice President, either manually or by facsimile signature, and shall have affixed thereto the Company's seal or a facsimile thereof which shall be attested by the Secretary or an Assistant Secretary of the Company, either manually or by facsimile signature. The Rights Certificates shall be manually countersigned by the Rights Agent and shall not be valid for any purpose unless so countersigned. In case any officer of the Company who shall have signed any of the Rights Certificates shall cease to be such officer of the Company before countersignature by the Rights Agent and issuance and delivery by the Company, such Rights Certificates nevertheless, may be countersigned by the Rights Agent and issued and delivered by the Company with the same force and effect as though the person who signed such Rights Certificates had not ceased to be such officer of the Company; and any Rights Certificates may be signed on behalf of the Company by any person who, at the actual date of the execution of such Rights Certificate, shall be a proper officer of the Company to sign such Rights Certificate, although at the date of the execution of this Rights Agreement any such person was not such an officer.

(b) Following the Distribution Date, the Rights Agent will keep or cause to be kept, at its principal office or offices designated as the appropriate place for surrender of Rights Certificates upon exercise or transfer, books for registration and transfer of the Rights Certificates issued hereunder. Such books shall show the names

9

Section 6. TRANSFER, SPLIT UP, COMBINATION AND EXCHANGE OF RIGHTS CERTIFICATES; MUTILATED, DESTROYED, LOST OR STOLEN RIGHTS CERTIFICATES.

(a) Subject to the provisions of Section 4(b), Section 7(e) and
Section 14 hereof, at any time after the close of business on the Distribution Date, and at or prior to the close of business on the Expiration Date, any Rights Certificate or Certificates may be transferred, split up, combined or exchanged for another Rights Certificate or Certificates, entitling the registered holder to purchase a like number of one one-hundredths of a share of Preferred Stock or, following an Adjustment Event, Common Stock, other securities, cash or other assets, as the case may be) as the Rights Certificate or Certificates surrendered then entitled such holder (or former holder in the case of a transfer) to purchase. Any registered holder desiring to transfer, split up, combine or exchange any Rights Certificate or Certificates shall make such request in writing delivered to the Rights Agent, and shall surrender the Rights Certificate or Certificates to be transferred, split up, combined or exchanged at the principal office or offices of the Rights Agent designated for such purpose. Neither the Rights Agent nor the Company shall be obligated to take any action whatsoever with respect to the transfer of any such surrendered Rights Certificate until the registered holder shall have completed and signed the certificate contained in the Form of Assignment on the reverse side of such Rights Certificate and shall have provided such additional evidence of the identity of the Beneficial owner (or former Beneficial Owner) or Affiliates or Associates thereof or a bond as the Company or Rights Agent shall reasonably request. Thereupon the Rights Agent shall, subject to Section 4(b), Section 7(e) and Section 14 hereof, countersign and deliver to the Person entitled thereto a Rights Certificate or Rights Certificates, as the case may be, as so requested. The Company may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer, split up, combination or exchange of Rights Certificates.

(b) Upon receipt by the Company and the Rights Agent of evidence reasonably satisfactory to them of the loss, theft, destruction or mutilation of a Rights Certificate, and, in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to them, and reimbursement to the Company and the Rights Agent of all reasonable expenses incidental thereto, and upon surrender to the Rights Agent and cancellation of the Rights Certificate if mutilated, the Company will execute and deliver a new Rights Certificate of like tenor to the Rights Agent for countersignature and delivery to the registered owner in lieu of the Rights Certificate so lost, stolen, destroyed or mutilated.

Section 7. EXERCISE OF RIGHTS; PURCHASE PRICE; EXPIRATION DATE OF RIGHTS.

(a) Subject to Section 7(e) hereof, the registered holder of any Rights Certificate may exercise the Rights evidenced thereby (except as otherwise provided herein including, without limitation, the restrictions on exercisability set forth in Section 9(c), Section 11(a)(iii) and Section 23(a) hereof) in whole or in part at any time after the Distribution Date upon surrender of the Rights Certificate, with the Form of Election To Purchase and the certificate on the reverse side thereof duly executed, to the Rights Agent at the principal office or offices of the Rights Agent designated for such purpose, together with payment of the aggregate Purchase Price with respect to the total number of one one-hundredths of a share of Preferred Stock (or other securities, cash or other assets, as the case may be) as to which such surrendered Rights are then exercisable, at or prior to the earlier of (i) Final Expiration Date, or (ii) the time at which the Rights are redeemed as provided in Section 23 hereof (the earlier of (i) and
(ii) being herein referred to as the "Expiration Date").

(b) The Purchase Price for each one one-hundredth of a share of Preferred Stock pursuant to the exercise of a Right shall initially be $35.00, and shall be subject to adjustment from time to time as provided in Sections 11 and 13(a) hereof and shall be payable in accordance with paragraph (c) below.

(c) Upon receipt of a Rights Certificate representing exercisable Rights, with the Form of Election To Purchase and the certificate duly executed, accompanied by payment, with respect to each Right so exercised, of the Purchase Price per one one-hundredth of a share of Preferred Stock (or other shares securities, cash or other assets, as the case may be) to be purchased as set forth below and an amount equal to any applicable transfer tax, the Rights Agent shall,, subject to Section 20(k) hereof, thereupon promptly (i) (A) requisition from any transfer agent of the shares of Preferred Stock (or make available, if the Rights Agent is the transfer agent for such shares) certificates for the total number of one one-hundredths of a share of Preferred Stock to be purchased and the Company hereby irrevocably authorizes its transfer agent to comply with all such requests, or (B) if the Company shall have elected to deposit the total number of shares of Preferred Stock issuable upon exercise of the Rights hereunder with a depositary agent, requisition from the depositary agent depositary receipts representing such number of one one-hundredths of a share of Preferred Stock as are to be purchased (in which case certificates for the shares of Preferred Stock represented by such receipts shall be deposited by the transfer agent with the depositary agent) and the Company will direct the depositary agent to comply with such request, (ii) requisition from the Company the amount of cash, if any, to be paid in lieu of fractional shares in accordance with Section 14 hereof, (iii) after receipt of such certificates or depositary receipts, cause the same to be delivered to or upon the order of the registered holder of such Rights Certificate, registered in such name or names as may be designated by such holder, and (iv) after

11

receipt thereof, deliver such cash, if any, to or upon the order of the registered holder of such Rights Certificate. The payment of the Purchase Price (as such amount may be reduced pursuant to Section 11(a)(iii) hereof) shall be made in cash or by certified bank check or money order payable to the order of the Company. In the event that the Company is obligated to issue other securities (including Common Stock) of the Company, pay cash and/or distribute other property pursuant to Section 11(a) hereof, the Company will make all arrangements necessary so that such other securities, cash and/or other property are available for distribution to the Rights Agent, if and when appropriate.

(d) In case the registered holder of any Rights Certificate shall exercise less than all the Rights evidenced thereby, a new Rights Certificate evidencing Rights equivalent to the Rights remaining unexercised shall be issued by the Rights Agent and delivered to, or upon the order of, the registered holder of such Rights Certificate, registered in such name or names as may be designated by such holder, subject to the provisions of Section 14 hereof.

(e) Notwithstanding anything in this Agreement to the contrary, from and after the first occurrence of a Section 11(a)(ii) Event, any Rights beneficially owned by (i) an Acquiring Person or an Associate or Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person, or (iii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee prior to or concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person to holders of equity interests in such Acquiring Person or to any Person with whom the Acquiring Person has any continuing agreement, arrangement or understanding regarding the transferred Rights of (B) a transfer which the Board of Directors of the Company has determined is part of a plan, arrangement or understanding which has as a primary purpose or effect the avoidance of this Section 7(e), shall become null and void without any further action and no holder of such Rights shall have any rights whatsoever with respect to such Rights, whether under any provision of this Agreement or otherwise. The Company shall use all reasonable efforts to insure that the provisions of this Section 7(e) and Section 4(b) hereof are complied with, but shall have no liability to any holder of Rights Certificates or other Person as a result of its failure to make any determinations with respect to an Acquiring Person or any Affiliates, Associates or transferees hereunder.

(f) Notwithstanding anything in this Agreement to the contrary, neither the Rights Agent nor the Company shall be obligated to undertake any action with respect to a registered holder upon the occurrence of any purported exercise as set forth in this Section 7 unless such registered holder shall have
(i) completed and signed the certificate contained in the Form of Election To Purchase set forth on the reverse side of the Rights Certificate surrendered for such exercise, and (ii) provided such additional evidence of

12

the identity of the Beneficial owner (or former Beneficial Owner) or Affiliates or Associates thereof as the Company shall reasonably request.

Section 8. CANCELLATION AND DESTRUCTION OF RIGHTS CERTIFICATES. All Rights Certificates surrendered for the purpose of exercise, transfer, split up, combination or exchange shall, if surrendered to the Company or any of its agents to be delivered to the Rights Agent for cancellation or in cancelled form, or, if surrendered to the Rights Agent, shall be cancelled by it, and no Rights Certificates shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Agreement. The Company shall deliver to the Rights Agent for cancellation and retirement, and the Rights Agent shall so cancel and retire, any other Rights Certificate purchased or acquired by the Company otherwise than upon the exercise thereof. The Rights Agent shall deliver all cancelled Rights Certificates to the Company, or shall at the written request of the Company, destroy such cancelled Rights Certificates, and in such case shall deliver a certificate of destruction thereof to the Company.

Section 9. RESERVATION AND AVAILABILITY OF CAPITAL STOCK.

(a) The Company covenants and agrees that it will cause to be reserved and kept available out of its authorized and unissued shares of Preferred Stock (and, following the occurrence of an Adjustment Event, out of its authorized and unissued shares of Common Stock and/or other securities or out of its authorized and issued shares held in its treasury), the number of shares of Preferred Stock (and, following the occurrence of an Adjustment Event, Common Stock and/or other securities) that, as provided in this Agreement including Section 11(a)(ii) hereof, will be sufficient to permit the exercise in full of all outstanding Rights.

(b) If and so long as the shares of Preferred Stock (and, following the occurrence of an Adjustment Event, Common Stock and/or other securities) issuable and deliverable upon the exercise of the Rights are listed on any national securities exchange, the Company shall use its best efforts to cause, from and after such time as the Rights become exercisable, all shares reserved for such issuance to be listed on such exchange upon official notice of issuance upon such exercise.

(c) The Company shall use its best efforts to (i) file, as soon as practicable following the earliest date after the first occurrence of a Section
11(a)(ii) Event on which the consideration to be delivered by the Company upon exercise of the Rights has been determined in accordance with Section 11(a)(iii) hereof, a registration statement under the Act, with respect to the securities purchasable upon exercise of the Rights on an appropriate form, (ii) cause such registration statement to become effective as soon as practicable after such filing, and (iii) cause such registration statement to remain effective (with a prospectus at all times meeting the requirements of the Act) until

13

the earlier of (A) the date as of which the Rights are no longer exercisable for such securities, and (B) the date of the expiration of the Rights. The Company will also take such action as may be appropriate under, or to ensure compliance with, the securities or "blue sky" laws of the various states in connection with the exercisability of the Rights. The Company may temporarily suspend, for a period of time not to exceed ninety (90) days after the date set forth in clause
(i) of the first sentence of this Section 9(c), the exercisability of the Rights in order to prepare and file such registration statement and permit it to become effective. Upon any such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect. In addition, if the Company shall determine that a registration statement is required following the Distribution Date, the Company may temporarily suspend the exercisability of the Rights until such time as a registration statement has been declared effective. Notwithstanding any provision of this Agreement to the contrary, the Rights shall not be exercisable in any Jurisdiction, unless the requisite qualification in such jurisdiction shall have been obtained and until a registration statement has been declared effective.

(d) The Company covenants and agrees that it will take all such action as may be necessary to ensure that all one one-hundredths of a share of Preferred Stock (and, following the occurrence of an Adjustment Event, Common Stock and/or other securities) delivered upon exercise of Rights shall, at the time of delivery of the certificates for such shares (subject to payment of the Purchase Price), be duly. and validly authorized and issued and fully paid and non-assessable.

(e) The Company further covenants and agrees that it will pay when due and payable any and all federal and state transfer taxes and charges which may be payable in respect of the issuance or delivery of the Rights Certificates and of any certificates for a number of one one-hundredths of a share of Preferred Stock (or Common Stock and/or other securities, as the case may be) upon the exercise of Rights. The Company shall not, however, be required to pay any transfer tax which may be payable in respect of any transfer or delivery of Rights Certificates to a Person other than, or the issuance or delivery of a number of one one-hundredths of a share of Preferred Stock (or Common Stock and/or other securities, as the case may be) in respect of a name other than that of, the registered holder of the Rights Certificates evidencing Rights surrendered for exercise or to issue or deliver any certificates for a number of one one-thousandths of a share of Preferred Stock (or Common Stock and/or other securities, as the case may be) in a name other than that of the registered holder upon the exercise of any Rights until such tax shall have been paid (any such tax being payable by the holder of such Rights Certificate at the time of surrender) or until it has been established to the Company's satisfaction that no such tax is due.

14

Section 10. PREFERRED STOCK RECORD DATE. Each person in whose name any certificate for a number of one one-hundredths of a share of Preferred Stock (or Common Stock and/or other securities, as the case may be) is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of such fractional shares of Preferred Stock (or Common Stock and/or other securities, as the case may be) represented thereby on, and such certificate shall be dated, the date upon which the Rights Certificate evidencing such Rights was duly surrendered and payment of the Purchase Price (and all applicable transfer taxes) was made; provided, however, that if the date of such surrender and payment is a date upon which the Preferred Stock (or Common Stock and/or other securities, as the case may be) transfer books of the Company are closed, such Person shall be deemed to have become the record holder of such shares (fractional or otherwise) on, and such certificate shall be dated, the next succeeding Business Day on which the Preferred Stock (or Common Stock and/or other securities, as the case may be) transfer books of the Company are open. Prior to the exercise of the Rights evidenced thereby, the holder of a Rights Certificate, as such, shall not be entitled to any rights of a shareholder of the Company with respect to shares for which the Rights shall be exercisable, including, without limitation, the right to vote, to receive dividends or other distributions or to exercise any preemptive rights, and shall not be entitled to receive any notice of any proceedings of the Company, except as provided herein.

Section 11. ADJUSTMENT OF PURCHASE PRICE, NUMBER AND KIND OF SHARES OR NUMBER OF RIGHTS. The Purchase Price, the number and kind of shares covered by each Right and the number of Rights outstanding are subject to adjustment from time to time as provided in this Section 11.

(a) (i) In the event the Company shall at any time after the date of this Agreement (A) declare a dividend on the Preferred Stock payable in shares of Preferred Stock, (B) subdivide the outstanding Preferred Stock,
(C) combine the outstanding Preferred Stock into a smaller number of shares, or (D) issue any shares of its capital stock in a reclassification of the Preferred Stock (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing or surviving corporation), except as otherwise provided in this Section 11(a) and Section 7(e) hereof, the Purchase Price in effect at the time of the record date for such dividend or of the effective date of such subdivision, combination or reclassification, and the number and kind of shares of Preferred Stock or capital stock, as the case may be, issuable on such date, shall be proportionately adjusted so that the holder of any Right exercised after such time shall be entitled to receive, upon payment of the Purchase Price then in effect, the aggregate number and kind of shares of Preferred Stock or capital stock, as the case may be, which, if such Right had been exercised immediately prior to such date and at a time when the Preferred Stock transfer books of the Company were open, he would have owned upon such exercise and been entitled to receive by

15

virtue of such dividend, subdivision, combination or reclassification. If an event occurs which would require an adjustment under both this Section 11(a)(i) and Section 11(a)(ii) hereof, the adjustment provided for in this
Section 11(a)(i) shall be in addition to, and shall be made prior to, any adjustment required pursuant to Section 11(a)(ii) hereof.

(ii) In the event:

(A) (1) any Acquiring Person or any Associate or Affiliate of any Acquiring Person, at any time after the date of this Agreement, directly or indirectly, shall merge into the Company or otherwise combine with the Company and the Company shall be the continuing or surviving corporation of such merger or combination and the Common Stock of the Company shall remain outstanding and unchanged, or (2) subject to the right of redemption granted in Section 24 hereof, any Person (other than the Company, any Subsidiary of the Company, any employee benefit plan of the Company or of any Subsidiary of the Company, or any Person or entity organized, appointed or established by the Company for or pursuant to the terms of any such plan), alone or together with its Affiliates and Associates, shall, at any time after the Rights Dividend Declaration Date, become an Acquiring Person, other than pursuant to any transaction set forth in Section 13(a) hereof, or pursuant to an offer for all outstanding shares of Common Stock at a price and upon such terms and conditions as a majority of the Board of Directors determines to be in the best interests of the Company and its stockholders, other than such Acquiring Person, its Affiliates and its Associates, or

(B) during such time as there is an Acquiring Person, there shall be any reclassification of securities (including any reverse stock split), or recapitalization of the Company, or any merger or consolidation of the Company with any of its Subsidiaries or any other transaction or series of transactions involving the Company or any of its Subsidiaries, other than a transaction or transactions to which the provisions of Section 13(a) apply
(whether or not with or into or otherwise involving an Acquiring Person)
which has the effect, directly or indirectly, of increasing by more than 1% the proportionate share of the outstanding shares of any class of equity securities of the Company or any of its Subsidiaries which is directly or indirectly beneficially owned by any Acquiring Person or any Associate or Affiliate of any Acquiring Person,

then, promptly following the occurrence of a Section 11(a)(ii) Event, the Company and, to the extent necessary or appropriate, the Acquiring Person and its Affiliates and Associates, shall make proper provision so that each holder of a Right (except as provided below and in Section 7(e) hereof) shall thereafter have the right to receive, upon exercise thereof at the then current Purchase Price in accordance with the terms of this Agreement,

16

in lieu of a number of one one-hundredths of a share of Preferred Stock, such number of shares of Common Stock of the Company as shall equal the result obtained by (x) multiplying the then current Purchase Price by the then number of one one-hundredths of a share of Preferred Stock for which a Right was exercisable immediately prior to the first occurrence of a Section 11(a)(ii) Event, and (y) dividing that product (which, following such first occurrence, shall thereafter be referred to as the "Purchase Price" for each Right and for all purposes of this Agreement) by 50% of the current market price (determined pursuant to Section 11(d) hereof) per share of Common Stock on the date of such first occurrence (such number of shares, the "Adjustment Shares").

(iii) In the event that the number of shares of Common Stock which are authorized by the Company's Restated Articles of Incorporation but not outstanding or reserved for issuance for purposes other than upon exercise of the Rights are not sufficient to permit the exercise in full of the Rights in accordance with the foregoing subparagraph (ii) of this Section
11(a), the Company shall: (A) determine the excess of (1) the value of the. Adjustment Shares issuable upon the exercise of a Right (the "Current Value") over (2) the Purchase Price (such excess, the "Spread"), and (B) with respect to each Right, make adequate provision to substitute for the Adjustment Shares, upon payment of the applicable Purchase Price, (1) cash,
(2) a reduction in the Purchase Price, (3) Common Stock or other equity securities of the Company (including, without limitation, shares, or units of shares, of preferred stock which the Board of Directors of the Company has deemed to have the same value as shares of Common Stock (such shares of preferred stock, "Common stock equivalents")), (4) debt securities of the Company, (5) other assets or (6) any combination of the foregoing, having an aggregate value equal to the Current Value, where such aggregate value has been determined by the Board of Directors of the Company based upon the advice of a nationally recognized investment banking firm selected by the Board of Directors of the Company; provided, however, if the Company shall not have made adequate provision to deliver value pursuant to clause (B) above within thirty (30) days following the later of (x) the first occurrence of a Section 11(a)(ii) Event and (y) the date on which the Company's right of redemption pursuant to Section 23(a) expires (the later of (x) and (y) being referred to herein as the "Section 11(a)(ii) Adjustment Date"), then the Company shall be obligated to deliver, upon the surrender for exercise of a Right and without requiring payment of the Purchase Price shares of Common Stock (to the extent available) and then, if necessary, cash, which shares and/or cash have an aggregate value equal to the Spread. If the Board of Directors of the Company shall determine in good faith that it is likely that sufficient additional shares of Common Stock could be authorized for issuance upon exercise in full of the Rights, the thirty (30) day period set forth above may be extended to the extent necessary, but not more than ninety (90) days after the

17

Section 11(a)(ii) Adjustment Date, in order that the Company may seek shareholder approval for the authorization of such additional shares (such period, as it may be extended, the "Substitution Period"). To the extent that the Company determines that some action need be taken pursuant to the first and/or second sentences of this Section 11(a)(iii), the Company (x) shall provide, subject to Section 7(e) hereof, that such action shall apply uniformly to all outstanding Rights, and (y) may suspend the exercisability of the Rights until the expiration of the Substitution Period in order to seek any authorization of additional shares and/or to decide the appropriate form of distribution to be made pursuant to such first sentence and to determine the value thereof. In the event of any such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect. For purposes of this Section 11(a)(iii), the value of the Common Stock shall be the current market price (as determined pursuant to Section 11(d) hereof) per share of the Common Stock on the Section 11(a)(ii) Adjustment Date and the value of any "Common stock equivalent" shall be deemed to have the same value as the Common Stock on such date.

(b) In case the Company shall fix a record date for the issuance of rights, options or warrants to all holders of Preferred Stock entitling them to subscribe for or purchase (for a period expiring within forty-five (45) calendar days after such record date) Preferred Stock (or shares having the same rights, privileges and preferences as the shares of Preferred' Stock ("equivalent preferred stock")) or securities convertible into Preferred Stock or equivalent preferred stock at a price per share of Preferred Stock or per share of equivalent preferred stock (or having a conversion price per share, if a security convertible into Preferred Stock or equivalent preferred stock) less than the current market price (as determined pursuant to Section 11(d) hereof) per share of Preferred Stock on such record date, the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the number of shares of Preferred Stock outstanding on such record date, plus the number of shares of Preferred Stock which the aggregate offering price of the total number of shares of Preferred Stock and/or equivalent preferred stock so to be offered (and/or the aggregate initial conversion price of the convertible securities so to be offered) would purchase at such current market price,. and the denominator of which shall be the number of shares of Preferred Stock outstanding on such record. date, plus the number of additional shares of Preferred Stock and/or equivalent preferred stock to be offered for subscription or purchase (or into which the convertible securities so to be offered are initially convertible). In case such subscription price may be paid by delivery of consideration part or all of which may be in a form other than cash, the value of such consideration shall be as determined. in good

18

faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of the Rights. Shares of Preferred Stock owned by or held for the account of the Company shall not be deemed outstanding for the purpose of any such computation. Such adjustment shall be made successively whenever such a record date is fixed, and in the event that such rights or warrants are not so issued, the Purchase Price shall be adjusted to be the Purchase Price which would then be in effect if such record date had not been fixed.

(c) In case the Company shall fix a record date for a distribution to all holders of Preferred Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation) of evidences of indebtedness, cash (other than a regular quarterly cash dividend out of the earnings or retained earnings of the Company), assets (other than a dividend payable in Preferred Stock, but including any dividend payable in stock other than Preferred Stock) or subscription rights or warrants (excluding those referred to in Section 11(b) hereof), the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the current market price (as determined pursuant to
Section 11(d) hereof) per share of Preferred Stock on such record date, less the fair market value (as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent) of the portion of the cash, assets or evidences of indebtedness so to be distributed or of such subscription rights or warrants applicable to a share of Preferred Stock and the denominator of which shall be such current market price (as determined pursuant to Section 11(d) hereof) per share of Preferred Stock. Such adjustments shall be made successively whenever such a record date is fixed, and in the event that such distribution is not so made, the Purchase Price shall be adjusted to be the Purchase Price which would have been in effect if such record date had not been fixed.

(d) (i) For the purpose of any computation hereunder, other than computations made pursuant to Section 11(a)(iii) hereof, the "Current market price" per share of Common Stock on any date shall be deemed to be the average of the daily closing prices per share of such Common Stock for the thirty (30) consecutive Trading Days (as such term is hereinafter defined) immediately prior to such date, and for purpose of computations made pursuant to Section 11(a) (iii) hereof, the "Current market price" per share of Common Stock on any date shall be deemed to be the average of the daily closing prices per share of such Common Stock for the ten (10) consecutive Trading Days immediately following such date; provided, however, that in the event that the current market price per share of the Common Stock is determined during a period following the announcement by the issuer of such Common Stock of (A) a dividend or distribution on such Common

19

Stock payable in shares of such Common Stock or securities convertible into shares of such Common Stock (other than the Rights), or (B) any subdivision, combination or reclassification of such Common Stock, and prior to the expiration of the requisite thirty (30) Trading Day or ten
(10) Trading Day period, as set forth above, after the ex-dividend date for such dividend or distribution, or the record date for such subdivision, combination or reclassification, then, and in each such case, the "Current market price" shall be properly adjusted to take into account ex-dividend trading. The closing price for each day shall be the last sale price, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the shares of Common Stock are not listed or admitted to trading on the New York Stock Exchange, as reported in the principal consolidated transaction reporting system with respect to securities listed on the principal national securities exchange on which the shares of Common Stock are listed or admitted to trading or, if the shares of Common Stock are not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by the National Association of Securities Dealers, Inc. Automated Quotation System ("NASDAQ") or such other system then in use, or, if on any such date the shares of Common Stock are not quoted by any such organization, the average or the closing bid and asked prices as furnished by a professional market maker making a market in the Common Stock selected by the Board of Directors of the Company. If on any such date no market maker is making a market in the Common Stock, the fair value of such shares on such date as determined in good faith by the Board of Directors of the Company shall be used. The term "Trading Day" shall mean a day on which the principal national securities exchange on which the shares of Common Stock are listed or admitted to trading is open for the transaction of business or, if the shares of Common Stock are not listed or admitted to trading on any national securities exchange, a Business Day. If the Common Stock is not publicly held or not so listed or traded, "Current market price" per share. shall. mean the fair value per share as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes.

(ii) For the purpose of any computation hereunder, the "Current market price" per share of Preferred Stock shall be determined in the same manner as set forth above for the Common Stock in clause (i) of this Section 11(d) (other than the last sentence thereof). If the current market price per share of Preferred Stock cannot be determined in the manner provided above or if the Preferred Stock is not publicly held or listed or traded in a manner described in clause (i) of this Section

20

11(d), the "Current market price" per share of Preferred Stock shall be conclusively deemed to be an amount equal to 100 (as such number may be appropriately adjusted for such events as stock splits, stock dividends and recapitalizations with respect to the Common Stock occurring after the date of this Agreement) multiplied by the current market price per share of the Common Stock. If neither the Common Stock nor the Preferred Stock is publicly held or so listed or traded, "Current market price" per share of the Preferred Stock shall mean the fair value per share as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes. For all purposes of this Agreement, the "Current market price" of one one-hundredth of a share of Preferred Stock shall be equal to the "Current market price" of one share of Preferred Stock divided by 100.

(e) Anything herein to the contrary notwithstanding, no adjustment in the Purchase Price shall be required unless such adjustment would require an increase or decrease of at least one percent (1%) in the Purchase Price; provided, however, that any adjustments which by reason of this Section 11(e) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 11 shall be made to the nearest cent or to the nearest one-thousandth of a share of Common Stock or other share or one-millionth of a share of Preferred Stock, as the case may be. Notwithstanding the first sentence of this Section 11(e), any adjustment required by this Section 11 shall be made no later than the earlier of (i) three
(3) years from the date of the transaction which mandates such adjustment, or
(ii) the Expiration Date.

(f) If as a result of an adjustment made pursuant to Section 11(a)(ii) or Section 13(a) hereof, the holder of any Right thereafter exercised shall become entitled to receive any shares of capital stock other than Preferred Stock, thereafter the number of such other shares so receivable upon exercise of any Right and the Purchase Price thereof shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Preferred Stock contained in Sections 11(a), (b), (c), (e), (g), (h), (i), (j), (k) and (m), and the provisions of Sections 7, 9, 10, 13 and 14 hereof with respect to the Preferred Stock shall apply on like terms to any such other shares.

(g) All Rights originally issued by the Company subsequent to any adjustment made to the Purchase Price hereunder shall evidence the right to purchase, at the adjusted Purchase Price, the number of one one-hundredths of a share of Preferred Stock purchasable from time to time hereunder upon exercise of the Rights, all subject to further adjustment as provided herein.

21

(h) Unless the Company shall have exercised its election as provided in Section 11(i), upon each adjustment of the Purchase Price as a result of the calculations made in Sections 11(b) and (c), each Right outstanding immediately prior to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted Purchase Price, that number of one-hundredths of a share of Preferred Stock (calculated to the nearest one-millionth) obtained by
(i) multiplying (x) the number of one one-hundredths of a share covered by a Right immediately prior to this adjustment, by (y) the Purchase Price in effect immediately prior to such adjustment of the Purchase Price, and (ii) dividing the product so obtained by the Purchase Price in effect immediately after such adjustment of the Purchase Price.

(i) The Company may elect on or after the date of any adjustment of the Purchase Price to adjust the number of Rights, in lieu of any adjustment in the number of one one-hundredths of a share of Preferred Stock, purchasable upon the exercise of a Right. Each of the Rights outstanding after the adjustment in the number of Rights shall be exercisable for the number of one one-hundredths of a share of Preferred Stock for which a Right was exercisable immediately prior to such adjustment. Each Right held of record prior to such adjustment of the number of Rights shall become that number of Rights (calculated to the nearest one-thousandth) obtained by dividing the Purchase Price in effect immediately prior to adjustment of the Purchase Price by the Purchase Price in effect immediately after adjustment of the Purchase Price. The Company shall make a public announcement of its election to adjust the number of Rights, indicating the record date for the adjustment, and, if known at the time, the amount of the adjustment to be made. This record date may be the date on which the Purchase Price is adjusted or any day thereafter, but, if the Rights Certificates have been issued, shall be at least ten (10) days later than the date of the public announcement. If Rights Certificates have been issued, upon each adjustment of the number of Rights pursuant to this Section 11(i), the Company shall, as promptly as practicable, cause to be distributed to holders of record of Rights Certificates on such record date Rights Certificates evidencing, subject to Section 14 hereof, the additional Rights to which such holders shall be entitled as a result of such adjustment, or, at the option of the Company, shall cause to be distributed to such holders of record in substitution and replacement for the Rights Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Company, new Rights Certificates evidencing all the Rights to which such holders shall be entitled after such adjustment. Rights Certificates so to be distributed shall be issued, executed and countersigned in the manner provided for herein (and may bear, at the option of the Company, the adjusted Purchase Price) and shall be registered in the names of the holders of record of Rights Certificates on the record date specified in the public announcement.

(j) Irrespective of any adjustment or change in the Purchase Price or the number of one one-hundredths of a share of Preferred Stock issuable upon the exercise of the Rights, the Rights Certificates theretofore and thereafter issued may continue to

22

express the Purchase Price per one one-hundredths of a share and the number of one one-hundredths of a share which were expressed in the initial Rights Certificates issued hereunder.

(k) Before taking any action that would cause an adjustment reducing the Purchase Price below the then stated value, if any, of the number of one one-hundredths of a share of Preferred Stock issuable upon exercise of the Rights, the Company shall take any corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue fully paid and non-assessable such number of one one-hundredths of a share of Preferred Stock at such adjusted Purchase Price.

(1) In any case in which this Section 11 shall require that an adjustment in the Purchase Price be made effective as of a record date for a specified event, the Company may elect to defer until the occurrence of such event the issuance to the holder of any Right exercised after such record date the number of one one-hundredths of a share of Preferred Stock and other capital stock or securities of the Company, if any, issuable upon such exercise over and above the number of one one-hundredths of a share of Preferred Stock and other capital stock or securities of the Company, if any, issuable upon such exercise on the basis of the Purchase Price in effect prior to such adjustment; provided, however, that the Company shall deliver to such holder a due bill or other appropriate instrument evidencing such holder's right to receive such additional shares (fractional or otherwise) or securities upon the occurrence of the event requiring such adjustment.

(m) Anything in this Section 11 to the contrary notwithstanding, the Company shall be entitled to make such reductions in the Purchase Price, in addition to those adjustments expressly required by this Section 11, as and to the extent that in their good faith judgment the Board of Directors of the Company shall determine to be advisable in order that any (I) consolidation or subdivision of the Preferred Stock, (ii) issuance wholly for cash of any shares of Preferred Stock at less than the current market price, (iii) issuance wholly for cash of shares of Preferred Stock or securities which by their terms are convertible into or exchangeable for shares of Preferred Stock, (iv) stock dividends or (v) issuance of rights, options or warrants referred to in this
Section 11, hereafter made by the Company to holders of its Preferred Stock shall not be taxable to such shareholders.

(n) The Company covenants and agrees that it shall not, at any time after the Distribution Date, (i) consolidate with any other Person (other than a Subsidiary of the Company in a transaction which complies with Section 11(o) hereof), (ii) merge with or into any other Person (other than a Subsidiary of the Company in a transaction which complies with Section 11(o) hereof), or (iii) sell or transfer (or permit any Subsidiary to

23

sell or transfer), in one transaction, or a series of related transactions, assets or earning power aggregating more than 50% of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to any other Person or Persons (other than a Company and/or any of its Subsidiaries in one or more transactions each of which complies with Section 11(o) hereof), if (x) at the time of or immediately after such consolidation, merger, sale or transfer there are any rights, warrants or other instruments or securities outstanding or agreements in effect which would substantially diminish or otherwise eliminate the benefits intended to be afforded by the Rights or (y) prior to, simultaneously with or immediately after such consolidation, merger, sale or transfer, the shareholders of the Person who constitutes, or would constitute, the "Principal Party" for purposes of Section 13(a) hereof shall have received a distribution of Rights previously owned by such Person or any of its Affiliates and Associates.

(o) The Company covenants and agrees that, after the Distribution Date, it will not, except as permitted by Section 23 or Section 26 hereof, take (or permit any Subsidiary to take) any action if at the time such action is taken it is reasonably foreseeable that such action will diminish substantially or otherwise eliminate the benefits intended to be afforded by the Rights.

(p) Anything in this Agreement to the contrary notwithstanding, in the event that the Company shall at any time after the Rights Dividend Declaration Date and prior to the Distribution Date (i) declare a dividend on the outstanding shares of Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding shares of Common Stock, or (iii) combine the outstanding shares of Common Stock into a smaller number of shares, the number of Rights associated with each share of Common Stock. then outstanding, or issued or delivered thereafter but prior to the Distribution Date, shall be proportionately adjusted so that the number of Rights thereafter associated with each share of Common Stock following any such event shall equal the result obtained by multiplying the number of Rights associated with each share of Common Stock immediately prior to such event by a fraction the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior to the occurrence of the event and the denominator of which shall be the total number of shares of Common Stock outstanding immediately following the occurrence of such event.

Section 12. CERTIFICATE OF ADJUSTED PURCHASE PRICE OR NUMBER OF SHARES. Whenever an adjustment is made as provided in Section 11 and Section 13 hereof, the Company shall (a) promptly prepare a certificate setting forth such adjustment and a brief statement of the facts accounting for such adjustment, (b) promptly file with the Rights Agent, and with each transfer agent for the Preferred Stock and the Common Stock, a copy of such certificate, and (c) mail a brief summary thereof to each holder of a Rights Certificate (or, if prior to the Distribution Date, to each holder of a certificate representing shares of Common Stock) in accordance with Section 25 hereof. The Rights Agent shall

24

be fully protected in relying on any such certificate and on any adjustment therein contained.

Section 13. CONSOLIDATION, MERGER OR SALE OR TRANSFER OF ASSETS OR EARNING POWER.

(a) In the event that, following the Stock Acquisition Date, directly or indirectly, (x) the Company shall consolidate with, or merge with and into, any other Person (other than a Subsidiary of the Company in a transaction which complies with Section 11(o) hereof), and the Company shall not be the continuing or surviving corporation of such consolidation or merger, (y) any Person (other than Subsidiary of the Company in a transaction which complies with Section 11(o) hereof) shall consolidate with, or merge with or into, the Company, and the Company shall be the continuing or surviving corporation of such consolidation or merger and, in connection with such consolidation or merger, all or part of the outstanding shares of Common Stock shall be changed into or exchanged for stock or other securities of any other Person or cash or any other property, or (z) the Company shall sell or otherwise transfer (or one or more of its Subsidiaries shall sell or otherwise transfer), in one transaction or a series of related transactions, assets or earning power aggregating more than 50% of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to any Person or Persons (other than the Company or any Subsidiary of the Company in one or more transactions each of which complies with Section 11(o) hereof), then, and in each such case, proper provision shall be made so that: (i) each holder of a Right, except as provided in Section 7(e) hereof, shall thereafter have the right to receive, upon the exercise thereof at the then current Purchase Price in accordance with the terms of this Agreement, such number of validly authorized and issued, fully paid, non-assessable and freely tradeable shares of Common Stock of the Principal Party (as such term is hereinafter defined), not subject to any liens, encumbrances, rights of first refusal or other adverse claims, as shall be equal to the result obtained by (1) multiplying the then current Purchase Price by the number of one-hundredths of a share of Preferred Stock for which a Right is exercisable immediately prior to the first occurrence of a Section 13 Event (or, if a Section 11(a)(ii) Event has occurred prior to the first occurrence of a Section 13 Event, multiplying the number of such one-hundredths of a share of Preferred Stock for which a Right was exercisable immediately prior to the first occurrence of a Section 11(a)(ii) Event by the Purchase Price in effect immediately prior to such first occurrence), and dividing that product (which, following the first occurrence of a Section 13 Event, shall be referred to as the "Purchase Price" for each Right and for all purposes of this Agreement) by (2) 50% of the current market price (determined pursuant to Section 11(d)(i) hereof) per share of the Common Stock of such Principal Party on the date of consummation of such Section 13 Event;
(ii) such Principal Party shall thereafter be liable for, and shall assume, by virtue of such Section 13 Event, all the obligations and duties of the Company pursuant to this Agreement; (iii) the term "Company" shall thereafter be deemed to refer to such Principal Party, it being specifically intended that the provisions of Section 11 hereof

25

shall apply to such Principal Party following the first occurrence of a Section 13 Event; (iv) such Principal Party shall take such steps (including, out not limited to, the reservation of a sufficient number of shares of its Common Stock) in connection with the consummation of any such transaction as may be necessary to assure that the provisions hereof shall thereafter be applicable, as nearly as reasonably may be, in relation to its shares of Common Stock thereafter deliverable upon the exercise of the Rights; and (v) the provisions of Section 11(a)(ii) hereof shall be of no effect following the first occurrence of any Section 13 Event.

(b) "Principal Party" shall mean

(i) in the case of any transaction described in clause (x) of (y) of the first sentence of Section 13(a), the Person that is the issuer of any securities into which shares of Common Stock of the Company are converted in such merger or consolidation, and if no securities are so issued, the Person that is the other party to such merger or consolidation; and

(ii) in the case of any transaction described in clause (z) of the first sentence of Section 13(a), the Person that is the party receiving the greatest portion of the assets or earning power transferred pursuant to such transaction or transactions;

PROVIDED, however, that in any such case, (1) if the Common Stock of such Person is not at such time and has not been continuously over the preceding twelve (12) month period registered under Section 12 of the Exchange Act, and such Person is a direct or indirect subsidiary of another person, the Common Stock of which is and has been so registered, "Principal Party" shall refer to such other Person; and (2) in case such Person is a subsidiary, directly or indirectly, of more than one Person, the Common Stocks of two or more of which are and have been so registered, "Principal Party" shall refer to whichever of such Persons is the issuer of the Common Stock having the greatest aggregate market value.

(c) The Company shall not consummate any such consolidation, merger, sale or transfer unless the Principal Party shall have a sufficient number of authorized shares of its Common Stock which have not been issued or reserved for issuance to permit the exercise in full of the Rights in accordance with this
Section 13 and unless prior thereto the Company and such Principal Party shall have executed and delivered to the Rights Agent a supplemental agreement providing for the terms set forth in paragraphs (a) and (b) of this Section 13 and further providing that, as soon as practicable after the date of any consolidation, merger, sale or transfer mentioned in paragraph (a) of this
Section 13, the Principal Party will

26

(i) prepare and file a registration statement under the Act, with respect to the Rights and the securities purchasable upon exercise of the Rights on an appropriate form, and will use its best efforts to cause such registration statement to (A) become effective as soon as practicable after such filing and (S) remain effective (with a prospectus at all times meeting the requirements of the Act) until the Expiration Date; and

(ii) will deliver to holders of the Rights historical financial statements for the Principal Party and each of its Affiliates which comply in all respects with the requirements for registration on Form 10 under the Exchange Act.

The provisions of this Section 13 shall similarly apply to successive mergers or consolidations or sales or other transfers. In the event that a Section 13 Event shall occur at any time after the occurrence of a Section 11(a)(ii) Event, the Rights which have not theretofore been exercised shall thereafter become exercisable in the manner described in Section 13(a).

Section 14. FRACTIONAL RIGHTS AND FRACTIONAL SHARES.

(a) The Company shall not be required to issue fractions of Rights, except prior to the Distribution Date as provided in Section 11(p) hereof, or to distribute Rights Certificates which evidence fractional Rights. In lieu of such fractional Rights, there shall be paid to the registered holders of the Rights Certificates with regard to which such fractional Rights would otherwise be issuable, an amount in cash equal to the same fraction of the current market value of a whole Right. For purposes of this Section 14(a), the current market value of a whole Right shall be the closing price of the Rights for the Trading Day immediately prior to the date on which such fractional Rights would have been otherwise issuable. The closing price of the Rights for any day shall be the last sale price, regular way, or, in case no such sale take place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the Rights are not listed or admitted to trading on the New York Stock Exchange, as reported in the principal consolidated transaction reporting system with respect to securities listed on the principal national securities exchange on which the Rights are listed or admitted to trading, or if the Rights are not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter, market, as reported by NASDAQ or such other system then in use or if . on any such date the Rights are not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Rights selected by the Board of Directors of the Company. If on any such date no such

27

market maker is making a market in the Rights the fair value of the Rights on such date as determined in good faith by the Board of Directors of the Company shall be used.

(b) The Company shall not be required to issue fractions of shares of Preferred Stock (other than fractions which are integral multiples of one one-hundredth of a share of Preferred Stock) upon exercise of the Rights or to distribute certificates which evidence fractional shares of Preferred Stock (other than fractions which are integral multiples of one one-hundredth of a share of Preferred Stock). In lieu of fractional shares of Preferred Stock that are not integral multiples of one one-hundredth of a share of Preferred Stock, the Company may pay to the registered holders of Rights Certificates at the time such Rights are exercised as herein provided an amount in cash equal to the same fraction of the current market value of one one-hundredths of a share of Preferred Stock. For purposes of this Section 11(b), the current market value of one one-hundredth of a share of Preferred Stock shall be one one-hundredth of the closing price of a share of Preferred Stock (as determined pursuant to
Section 11(d)(ii) hereof) for the Trading Day immediately prior to the date of such exercise.

(c) Following the occurrence of an Adjustment Event, the Company shall not be required to issue fractions of shares of Common Stock upon exercise of the Rights or to distribute certificates which evidence fractional shares of Common Stock. In lieu of fractional shares of Common Stock, the Company may pay to the registered holders of Rights Certificates at the time such Rights are exercised as herein provided an amount in cash equal to the same fraction of the current market value of one (1) share of Common Stock. For purposes of this
Section 14(c) the current market value of one share of Common Stock shall be the closing price of one share of Common Stock (as determined pursuant to Section 11(d)(i) hereof for the Trading Day immediately prior to the date of such exercise.

(d) The holder of a Right by the acceptance of the Rights expressly waives his right to receive any fractional Rights or any fractional shares upon exercise of a Right, except as permitted by this Section 14.

Section 15. RIGHTS OF ACTION. All rights of action in respect of this Agreement, other than rights of action vested in the Rights Agent pursuant to section 18 hereof, are vested in the respective registered holders of the Rights Certificates (and, prior to the Distribution Date, the registered holders of the Common Stock); and any registered holder of any Rights Certificate (or, prior to the Distribution Date, of the Common Stock), without the consent of the Rights Agent or of the holder of any other Rights Certificate (or, prior to the Distribution Date, of the Common Stock), may, in his own behalf and for his own benefit, enforce, and may institute and maintain any suit, action or proceeding against the Company to enforce, or otherwise act in respect of, his right to exercise the Rights evidenced by such Rights Certificate in the manner provided in such

28

Rights Certificate and in this Agreement. Without limiting the foregoing or any remedies available to the holders of Rights, it is specifically acknowledged that the holders of Rights would not have an adequate remedy at law for any breach of this Agreement and shall be entitled to specific performance of the obligations hereunder and injunctive relief against actual or threatened violations of the obligations hereunder of any Person subject to this Agreement.

Section 16. AGREEMENT OF RIGHTS HOLDERS. Every holder of a Right by accepting the same consents and agrees with the Company and the Rights Agent and with every other holder of a Right that:

Section 7(e) hereof, shall be required to be affected by any notice to the contrary; and

(d) notwithstanding anything in this Agreement to the contrary, neither the Company nor the Rights Agent shall have any liability to any holder of a Right or other Person as a result of its inability. to perform any of its obligations under this Agreement by reason of any preliminary or permanent injunction or other order, decree or ruling issued by a court of competent jurisdiction or by a governmental, regulatory or administrative agency or commission, or any statute, rule, regulation or executive order promulgated or enacted by any governmental authority, prohibiting or otherwise restraining performance of such obligation; PROVIDED, however, the Company must use its best efforts to have any such order, decree or ruling lifted or otherwise overturned as soon as possible.

29

Section 17. RIGHTS CERTIFICATE HOLDER NOT DEEMED A SHAREHOLDER. No holder, as such, of any Rights Certificate shall be entitled to vote, receive dividends or be deemed for any purpose the holder of the number of one one-hundredths of a share of Preferred Stock or any other securities of the Company which may at any time be issuable on the exercise of the Rights represented thereby, nor shall anything contained herein or in any Rights Certificate be construed to confer upon the holder of any Rights Certificate, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting shareholders (except as provided in Section 14 hereof), or to receive dividends or subscription rights, or otherwise, until the Right or Rights evidenced by such Rights Certificate shall have been exercised in accordance with the provisions hereof.

Section 17. CONCERNING THE RIGHTS AGENT.

(a) The Company agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and disbursements and other disbursements incurred in the administration and execution of this Agreement and the exercise and performance of its duties hereunder.

(b) The Rights Agent shall be protected and shall incur no liability for or in respect of any action taken, suffered or omitted by it in connection with its administration of this Agreement in reliance upon any Rights Certificate or certificate for Common Stock or for other securities of the Company, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, statement or other paper or documents believed by it to be genuine and to be signed, executed and, where necessary, verified or acknowledged, by the proper Person or Persons.

Section 19. MERGER OR CONSOLIDATION OR CHANGE OF NAME OF RIGHTS AGENT.

(a) Any corporation into which the Rights Agent or any successor Rights Agent may be merged or with which it may be consolidated, or any corporation resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any corporation succeeding to the corporate trust or

30

stock transfer business of the Rights Agent or any successor Right Agent, shall be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto; PROVIDED, however, that such corporation would be eligible for appointment as a successor Rights Agent under the provisions of Section 21 hereof. In case at the time such successor Rights Agent shall succeed to the agency created by this Agreement, any of the Rights Certificates shall have been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of a predecessor Rights Agent and deliver such Rights Certificates so countersigned; and in case at that time any of the Rights Certificates shall not have been countersigned, any successor Rights Agent may countersign such Rights Certificates either in the name of the predecessor or in the name of the successor Rights Agent; and in all such cases such Rights Certificates shall have the full force provided in the Rights Certificates and in this Agreement.

Section 20. DUTIES OF RIGHTS AGENT. The Rights Agent undertakes the duties and obligations imposed by this Agreement upon the following terms and conditions, by all of which the Company and the holders of Rights Certificates, by their acceptance thereof, shall be bound:

(a) The Rights Agent may consult with legal counsel (who may be legal counsel for the Company), and the opinion of such counsel shall be full and complete authorization and protection to the Rights Agent as to any action taken or omitted by it in good faith and in accordance with such opinion.

(b) Whenever in the performance of its duties under this Agreement the Rights Agent shall deem it necessary or desirable that any fact or matter (including, without limitation, the identity of any Acquiring Person or Adverse Person and the determination of "Current market price") be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed by the Chief Executive Officer, the President, any Vice President, the Treasurer, any Assistant Treasurer, the Secretary or any Assistant Secretary of the Company and delivered to the Rights Agent; and such

31

certificate shall be full authorization to the Rights Agent for any action taken or suffered in good faith by it under the provisions of this Agreement in reliance upon such certificate.

Section 13 hereof or responsible for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment (except with respect to the exercise of Rights evidenced by Rights Certificates after receipt of the certificate described in Section 12 hereof setting forth any such adjustment); nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization of reservation of any shares of Common Stock or Preferred Stock to be issued pursuant to this Agreement or any Rights Certificate or as to whether any shares of Common Stock or Preferred Stock will, when so issued, be validly authorized and issued, fully paid and non-assessable.

(f) The Company agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Rights Agent for the carrying out or performing by the Rights Agent of the provisions of this Agreement.

Nothing herein shall preclude the Rights Agent from acting in any other capacity for the Company or for any other legal entity.

(i) The Rights Agent may execute and exercise any of the rights or powers hereby vested in it or performs any duty hereunder either itself or by or through its attorneys or agents, and the Rights Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorneys or agents or for any loss to the Company resulting from any such act, default, neglect or misconduct; PROVIDED, however, reasonable care was exercised in the selection and continued employment thereof.

(j) No provision of this Agreement shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of its rights if there shall be reasonable grounds for believing that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it.

(k) If, with respect to any Right Certificate surrendered to the Rights Agent for exercise or transfer, the certificate attached to the Form of Assignment or Form of Election To Purchase, as the case may be, has either not be completed or indicates an affirmative response to clause 1 and/or 2 thereof, the Rights Agent shall not take any further action with respect to such requested exercise of transfer without first consulting with the Company.

Section 21. CHANGE OF RIGHTS AGENT. The Rights Agent or any successor Rights Agent may resign and be discharged from its duties under this Agreement upon thirty (30) days' notice in writing mailed to the Company, and to each transfer agent of the Common Stock and Preferred Stock, by registered or certified mail, and to the holders of the Rights Certificates by first-class mail. The Company may remove the Rights Agent or any successor Rights Agent upon thirty (30) days, notice in writing, mailed to the Rights Agent or successor Rights Agent, as the case may be, and to each transfer agent of the Common Stock and Preferred Stock, by registered or certified mail, and to the holders of the Rights Certificates by first-class mail. If the Rights Agent shall resign or be removed or shall otherwise become incapable of acting, the Company shall appoint a successor to the Rights Agent. If the Company shall fail to make such appointment within a period of thirty (30) days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent or by the

33

holder of the Rights Certificate (who shall, with such notice, submit his Rights Certificate for inspection by the Company), then any registered holder of any Rights Certificate may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Company or by such a court, shall be (a) a corporation organized and doing business under the laws of the United States or of any state of the United States as long as such corporation is authorized to do business as a banking institution in the State of New York, in good standing, and having a principal office in the State of New York, which is authorized under such laws to exercise corporate trust powers and is subject to supervision or examination by federal or state authority and which has at the time of its appointment as Rights Agent a combined capital and surplus of at least $100,000,000 or (b) an affiliate of a corporation described in clause (a) of this sentence. After appointment, the successor Rights Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed; but the predecessor Rights Agent shall deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Company shall file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Stock and the Preferred Stock, and mail a notice thereof in writing to the registered holders of the Rights Certificates. Failure to give any notice provided for in this
Section 21, however, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of the successor Rights Agent, as the case may be.

Section 22. ISSUANCE OF NEW RIGHTS CERTIFICATES. Notwithstanding any of the provisions of this Agreement or of the Rights to the contrary, the Company may, at its option, issue new Rights Certificates evidencing Rights in such form as may be approved by its Board of Directors to reflect any adjustment or change in the Purchase Price and the number or kind or class of shares or other securities or property purchasable under the Rights Certificates made in accordance with the provisions of this Agreement. In addition, in connection with the issuance or sale of shares of Common Stock following the Distribution Date and prior to the redemption or expiration of the Rights, the Company (a) shall, with respect to shares of Common Stock so issued or sold pursuant to the exercise of stock options or under any employee plan or arrangement, or upon the exercise, conversion or exchange of securities hereinafter issued by the Company, and (b) may , in any other case, if deemed necessary or appropriate by the Board of Directors of the Company, issue Rights Certificates representing the appropriate number of Rights in connection with such issuance or sale; PROVIDED, however, that (i) no such Rights Certificate shall be issued it, and to the extent that, the Company shall be advised by counsel that such issuance would create a significantly risk of material adverse tax consequences to the Company or the person to whom such Rights Certificate would be

34

issued, and (ii) no such Rights Certificate shall be issued if, and to the extent that, appropriate adjustment shall otherwise have been made in lieu of the issuance thereof.

Section 23. REDEMPTION AND TERMINATION.

(a) The Board of Directors of the Company may, at any time prior to the earlier of (i) the close of business on the twentieth day following the Stock Acquisition Date or (ii) the Final Expiration Date, redeem all but not less than all the then outstanding Rights at a redemption price of $.05 per Right, as such amount may be appropriately adjusted to reflect any stock split, reverse stock split, reclassification, stock dividend or similar transaction occurring after the date hereof (such redemption price being hereinafter referred to as the "Redemption Price"); PROVIDED, however, that if, following the occurrence of a Stock Acquisition Date and following the expiration of the right of redemption hereunder but prior to any Adjustment Event, (i) a Person who is an Acquiring Person shall have transferred or otherwise disposed of a number of shares of Common Stock in one transaction or series of transactions, not directly or indirectly involving the Company or any of its Subsidiaries, which did not result in the occurrence of an Adjustment Event such that such Person is thereafter a Beneficial Owner of 10% or less of the outstanding shares of Common Stock, and (ii) there are no other Persons, immediately following the occurrence of the event described in clause (i), who are Acquiring Persons, then the right of redemption shall be reinstated and thereafter be subject to the provisions of this Section 23. Notwithstanding anything contained in this Agreement to the contrary, subject to Section 26 hereof, the Rights shall not be exercisable after the first occurrence of a Section 11(a)(ii) Event until such time as the Company's right of redemption hereunder has expired. The Company may, at its option, pay the Redemption Price in cash, shares of Common Stock (based on the "current market price," as defined in Section 11(d)(i) hereof, of the Common Stock at the time of redemption) or any other form of consideration deemed appropriate by the Board of Directors.

(b) Immediately upon the action of the Board of Directors of the Company ordering the redemption of the Rights, evidence of which shall have been filed with the Rights Agent and without any further action and without any notice, the right to exercise the Rights will terminate and the only right thereafter of the holder of Rights shall be to receive the Redemption Price for each Right so held. Promptly after the action of the Board of Directors ordering the redemption of the Rights, the Company shall give notice of such redemption to the Rights Agent and the holders of the then outstanding Rights by mailing such notice to all such holders at each holder's last address as it appears upon the registry books of the Transfer Agent for the Common Stock. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of redemption will state the method by which the payment of the Redemption Price will be made.

35

(c) The Company's Board of Directors may at any time after any Person becomes an Acquiring Person, exchange all or part of the then outstanding and exercisable Rights (which shall not include Rights that have become void pursuant to the provisions of Section 11(a)(ii) hereof) for shares of Common Stock at an exchange ratio of one share of Common Stock per Right, appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date hereof (such exchange ratio being hereinafter referred to as the "Exchange Ratio"). Notwithstanding the foregoing, the Board of Directors shall not be empowered to effect such exchange at any time after any person (other than the Company, any Subsidiary of the Company, any employee benefit plan of the Company or any such subsidiary or any entity holding shares of Common Stock for or pursuant to any such plan), together with all Affiliates and Associates of such Person, becomes the Beneficial Owner of Shares of Common Stock aggregating 50% or more of the shares of Common Stock then outstanding.

(d) Immediately upon the action of the Company's Board of Directors ordering the exchange of any Rights pursuant to paragraph (c) of this Section 23 and without any further action and without any notice, the right to exercise such Rights shall terminate and the only right thereafter of a holder of such Rights shall be to receive that number of shares of Common Stock equal to the number of such Rights held by such holder multiplied by the Exchange Ratio. The Company shall promptly give public notice of any such exchange; PROVIDED, HOWEVER, that the failure to give, or any defect in, such notice shall not affect the validity of such exchange. The Company shall mail promptly a notice of any such exchange to all of the holders of such Rights at their last addresses as they appear upon the registry books of the Rights Agent. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of exchange will state the method by which the exchange of the shares of Common Stock for Rights will be effected and, in the event of any partial exchange, the number of Rights which will be exchanged. Any partial exchange shall be effected pro rata based on the number of Rights (other than Rights which have become void pursuant to the provisions of Section 7(e) hereof) held by each holder of Rights.

(e) In the event that there shall not be sufficient shares of Common Stock issued but not outstanding or authorized but unissued to permit any exchange of Rights as contemplated in accordance with this Section 23, the Company shall take all such action as may be necessary to authorize additional shares of Common Stock for issuance upon exchange of the Rights. In the event the Company shall, after good faith effort, be unable to take all such action as may be necessary to authorize such additional shares of Common Stock, the Company shall substitute for each share of Common Stock that would otherwise be issuable upon exchange of a Right, a number of shares of Preferred Stock or fraction thereof such that the current per share market price of one share of Preferred Stock multiplied by such number or fraction is equal to the current per

36

share market price of one share of Common Stock as of the date of issuance of such share of Preferred Stock or fraction thereof.

(f) The Company shall not be required to issue fractions of shares of Common Stock or to distribute certificates which evidence fractional shares of Common Stock. In lieu of such fractional shares of Common Stock, the Company shall pay to the registered holders of the Right Certificates with regard to which such fractional shares of Common Stock would otherwise be issuable an amount in cash equal to the same fraction of the current market value of a whole share of Common Stock. For the purposes of this paragraph (f), the current market value of a whole share of Common Stock shall be the closing price of a share of Common Stock (as determined pursuant to the second sentence of Section 11(d)(i) hereof) for the Trading Day immediately prior to the date of exchange pursuant to this Section 23.

Section 24. NOTICE OF CERTAIN EVENTS.

(a) In case the Company shall propose, at any time after the Distribution Date, (i) to pay any dividend payable in stock of any class to the holders of Preferred Stock or to make any other distribution to the holders of Preferred Stock (other than a regular quarterly cash dividend out of earnings or retained earnings of the Company), or (ii) to offer to holders of Preferred Stock rights or warrants to subscribe for or to purchase any additional shares of Preferred Stock or shares of stock of any class or any other securities, rights or options, or (iii) to effect any reclassification of its Preferred Stock (other than a reclassification involving only the subdivision of outstanding shares of Preferred Stock), or (iv) to effect any consolidation or merger into or with any other Person other than a Subsidiary of the Company in a transaction which complies with Section 11(b) hereof, or to effect any sale or other transfer (or to permit one or more of its Subsidiaries to effect any sale or other transfer), in one transaction or a series of related transactions, of more than 50% of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to any other person or Persons (other than the Company and/or any of its Subsidiaries in one or more transactions each of which complies with
Section 11(o) hereof), or (v) to effect the liquidation, dissolution or winding up of the Company, then, in each such case, the Company shall give to each holder of a Rights Certificate, to the extent feasible and in accordance with
Section 25 hereof, a notice of such proposed action, which shall specify the record date for the purposes of such stock dividend, distribution of rights or warrants, or the date on which such reclassification, consolidation, merger, sale, transfer, liquidation, dissolution, or winding up is to take place and the date of participation therein by the holders of the shares of Preferred Stock, if any such date is to be fixed, and such notice shall be so given in the case of any action covered by clause (i) or (ii) above at least twenty (20) days prior to the record date for determining holders of the shares of Preferred Stock for purposes of such action, and in the case of any such other action, at least twenty (20) days prior to the date of the taking

37

of such proposed action of the date of participation therein by the holders of the shares of Preferred Stock which ever shall be the earlier.

(b) In case any of the events set forth in Section 11(a)(ii) hereof shall occur, then, in any such case, (i) the Company shall as soon as practicable thereafter give to each holder of the Rights Certificate, to the extent feasible and in accordance with Section 25 hereof a notice of the occurrence of such event, which shall specify the event and the consequences of the event to holders of Rights under Section 11(a)(ii) hereof, and (ii) all references in the preceding paragraph to Preferred Stock shall be deemed thereafter to refer to Common Stock and/or, if appropriate, other securities.

DATA I/O REPLACES EXPIRING SHAREHOLDER RIGHTS PLAN

REDMOND, WA --March 12, 1998. The Board of Directors of Data I/O Corporation (Nasdaq: DAIO) has adopted a new Shareholder Rights Plan which will replace its existing Shareholder Rights Plan when it expires on April 4, 1998. The new plan will go into effect simultaneously with the expiration of the existing plan. Like the existing plan, the new Rights Plan will assist Data I/O's shareholders in realizing fair value and equal treatment in the event of any attempted takeover of the Company and protect the Company and its shareholders against coercive takeover tactics.

The Company noted that its new Shareholder Rights Plan reflects modern developments in shareholder rights plans though remains similar to its prior plan and to those adopted by many other companies and is not in response to any known effort to acquire control of the Company.

Under the new Shareholder Rights Plan, a dividend of one Share Purchase Right is being declared for each share of Common Stock outstanding at the close of business on April 4, 1998. These new Rights will replace the currently outstanding Rights upon their expiration. No separate certificates evidencing the Rights will be issued unless and until they become exercisable.

PAGE 2

The new Rights generally will not be exercisable until a person or group acquires 15% or more of the Common Stock of the Company. In that event, each new Right will entitle the holder, other than the acquirer, to buy Common Stock with a market value of twice the new Right's then current exercise price (the intial exercise price is $30, subject to adjustment).

In addition, if the new Rights were triggered by such a non-approved acquisition and the Company were thereafter to be acquired in a merger in which all shareholders were not treated alike, shareholders with unexercised Rights would be entitled to purchase common stock of the acquirer with a value of twice the exercise price of the new Rights.

The Company's Board of Directors may redeem the new Rights for a nominal amount at any time prior to an event that causes the Rights to become exercisable. The new Rights will expire on April 4, 2008.
