                                RIGHTS AGREEMENT

      
      RIGHTS AGREEMENT, dated as of August 30, 1996 (the "Agreement"), between
Quest Medical, Inc., a Texas corporation (the "Company"), and KeyCorp
Shareholder Services, Inc., (the "Rights Agent").

                                   BACKGROUND

      On August 29, 1996 (the "Rights Dividend Declaration Date"), the Board of
Directors of the Company authorized and declared a dividend distribution of one
Right for each share of common stock, par value $.05 per share, of the Company
(the "Common Stock") outstanding at the Close of Business on September 12, 1996
(the "Record Date"), and has authorized the issuance of one Right (as such
number may be adjusted pursuant to the provisions of SECTION 11(P)) for each
share of Common Stock of the Company issued between the Record Date (whether
originally issued or delivered from the Company's treasury) and the
Distribution Date, each Right initially representing the right to purchase one
share of Common Stock of the Company upon the terms and subject to the
conditions set forth below (the "Rights");

      NOW, THEREFORE, in consideration of the premises and the mutual agreements
set forth in this Agreement, the parties hereby agree as follows:

      Section 1. Certain Definitions.  For purposes of this Agreement, the
following terms have the meanings indicated:

           (a) "Act" means the Securities Act of 1933, as amended.

           (b) "Acquiring Person" means any Person that, together with all
      Affiliates and Associates of such Person, is the Beneficial Owner of 15%
      or more of the shares of Common Stock then outstanding, but does not
      include (i) the Company; (ii) any Subsidiary of the Company; (iii) any
      employee benefit plan of the Company or of any Subsidiary of the Company;
      (iv) any Person organized, appointed, or established by the Company for
      or pursuant to the terms of any such plan; (v) any person that becomes an
      Acquiring Person pursuant to a Permitted Transaction; (vi) any Person
      that has become an Acquiring Person inadvertently and, within five
      Business Days of being requested by the Company to advise it regarding
      the same, certifies to the Company that such Person acquired beneficial
      ownership of shares of Common Stock in excess of 14.9% inadvertently or
      without knowledge of the terms of the Rights and such certification is
      accepted as true by a Requisite Majority acting in good faith, and such
      Person divests as promptly as practicable a sufficient amount of Common
      Stock so that such Person would no longer hold in excess of 14.9% of the
      Common Stock then outstanding; and (vii) any Person that becomes an
      Acquiring Person solely as a result of a reduction in the number of
      outstanding shares of Common Stock in a transaction that is approved by a
      Requisite

                                       1
<PAGE>   5



      Majority, provided that such Person will immediately be an Acquiring
      Person in the event such Person thereafter acquires any additional shares
      of Common Stock (other than as a result of a stock split or stock
      dividend) while the Beneficial Owner of 15% or more of the shares of
      Common Stock then outstanding.

           (c) "Affiliate" and "Associate" have the respective meanings
      ascribed to such terms in Rule 12b-2 of the General Rules and Regulations
      under the Exchange Act and in effect on the date of this Agreement.

           (d) A Person will be deemed the "Beneficial Owner" of, and will be
      deemed to "beneficially own," any securities that:

                 (i) such Person or any of such Person's Affiliates or
            Associates, directly or indirectly, has the right to acquire
            (whether such right is exercisable immediately or only after the
            passage of time or upon the occurrence of certain events) pursuant
            to any agreement, arrangement, or understanding (whether or not in
            writing) or upon the exercise of conversion rights, exchange
            rights, rights, warrants or options, or otherwise; provided,
            however, that a Person will not be deemed the "Beneficial Owner"
            of, or to "beneficially own," (A) securities tendered pursuant to a
            tender or exchange offer made by such Person or any of such
            Person's Affiliates or Associates until such tendered securities
            are accepted for purchase or exchange, (B) securities issuable upon
            exercise of Rights at any time prior to the occurrence of a
            Distribution Date, or (C) securities issuable upon exercise of
            Rights, which were acquired by such Person or any of such Person's
            Affiliates or Associates prior to the Distribution Date or pursuant
            to SECTION 3(A) or SECTION 22 (the "Original Rights") or pursuant
            to SECTION 11(I) in connection with an adjustment made with respect
            to any Original Rights;

                 (ii) such Person or any of such Person's Affiliates or
            Associates, directly or indirectly, has the right to vote or
            dispose of or has "beneficial ownership" of (as determined pursuant
            to Rule 13d-3 of the General Rules and Regulations under the
            Exchange Act), including pursuant to any agreement, arrangement, or
            understanding, whether or not in writing; provided, however, that a
            Person will not be deemed the "Beneficial Owner" of, or to
            "beneficially own," any security under this SECTION 1(C)(II) as a
            result of an agreement, arrangement, or understanding to vote such
            security if such agreement, arrangement, or understanding: (1)
            arises solely from a revocable proxy given in response to a public
            proxy or consent solicitation made pursuant to, and in accordance
            with, the applicable provisions of the General Rules and
            Regulations under the Exchange Act, and (2) is not also then
            reportable by such Person on Schedule 13D under the Exchange Act
            (or any comparable or successor report); or

                 (iii) are beneficially owned, directly or indirectly, by any
            other Person (or any Affiliate or Associate of such Person) with
            which such Person (or any of such Person's Affiliates or
            Associates) has any agreement, arrangement, or

                                       2

            understanding (whether or not in writing), for the purpose of
            acquiring, holding, voting (except pursuant to a revocable proxy as
            described in the proviso in SECTION 1(c)(II)), or disposing of any
            voting securities of the Company;

      provided, however, that nothing in this SECTION 1(c) will cause a Person
      engaged in business as an underwriter of securities to be the "Beneficial
      Owner" of, or to "beneficially own," any securities acquired through such
      Person's participation in good faith in a bona fide firm commitment

      holder of the Common Stock as of 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 (the "Rights
      Certificates"), evidencing one Right for each share of Common Stock so
      held, subject to adjustment as provided in this Agreement.   In the event
      that an adjustment in the number of Rights per share of Common Stock has
      been made pursuant to SECTION 11(p), at the time of distribution of the
      Rights Certificates, the Company will make the necessary and appropriate
      rounding adjustments (in accordance with SECTION 14(a)) so that Rights
      Certificates representing only whole numbers of Rights are distributed
      and cash is paid in lieu of any fractional Rights.   As of and after the
      Distribution Date, the Rights will be evidenced solely by such Rights
      Certificates.

           (b) As soon as practicable following the Record Date, the Company
      will send a copy of a Summary of Rights, in substantially the form of
      EXHIBIT B, 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 will also be the registered holders of the associated
      Rights.  Until the earlier of the Distribution Date or the Expiration
      Date (as defined in SECTION 7), the transfer of any certificates
      representing shares of Common Stock in respect of which Rights have been
      issued will also constitute the transfer of the Rights associated with
      such shares of Common Stock.

           (c) Rights will be issued in respect of all shares of Common Stock
      that are issued (whether originally issued or from the Company's
      treasury) after the Record Date

                                       5

      but prior to the earlier of the Distribution Date or the Expiration Date.
      Certificates representing such shares of Common Stock will also be
      deemed to be certificates for Rights, and will bear the following legend:

            THIS CERTIFICATE ALSO EVIDENCES AND ENTITLES THE HOLDER TO
            CERTAIN RIGHTS AS SET FORTH IN THE RIGHTS AGREEMENT BETWEEN
            QUEST MEDICAL, INC. (THE "COMPANY") AND KeyCorp Shareholder
            Services, Inc. (THE "RIGHTS AGENT") DATED AS OF AUGUST 30,
            1996 (AS AMENDED FROM TIME TO TIME, THE "RIGHTS AGREEMENT"),
            THE TERMS OF WHICH ARE HEREBY INCORPORATED IN THIS
            CERTIFICATE BY REFERENCE AND A COPY OF WHICH IS ON FILE AT
            THE PRINCIPAL OFFICES OF THE COMPANY.  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 COMPANY
            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.
            UNDER CERTAIN CIRCUMSTANCES SET FORTH IN THE RIGHTS
            AGREEMENT, RIGHTS BENEFICIALLY OWNED BY ANY PERSON WHO IS,
            WAS, OR BECOMES AN ACQUIRING PERSON OR ANY AFFILIATE OR
            ASSOCIATE OF AN ACQUIRING PERSON (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 the shares of Common Stock issued after the Record
      Date, until the earlier of (i) the Distribution Date or (ii) the
      Expiration Date, the Rights associated with the Common Stock represented
      by such certificates will be evidenced by such certificates alone and
      registered holders of Common Stock will also be the registered holders of
      the associated Rights, and the transfer of any of such certificates will
      also constitute the transfer of the Rights associated with the Common
      Stock represented by such certificates.


      Section 4.  Form of Rights Certificates.

            The Rights Certificates (and the forms of election to purchase and
      of assignment to be printed on the reverse of the rights certificates)
      will each be substantially in the form set forth in EXHIBIT A and may
      have such marks of identification or designation and such legends,
      summaries, or endorsements 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
      
                                       6
<PAGE>   10




      pursuant thereto or with any rule or regulation of any stock exchange or
      quotation system 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, the Rights Certificates, whenever distributed, will be dated
      as of the Record Date and on their face will entitle the holders of such
      Rights Certificates to purchase such number of shares of Common Stock as
      is set forth in such Rights Certificates at the price set forth in such
      Rights Certificates (such exercise price per share, the "Purchase
      Price"), but the amount and type of securities purchasable upon the
      exercise of each Right and the Purchase Price will be subject to
      adjustment as provided in this Agreement.

      Section 5. Countersignature and Registration.

           (a) The Rights Certificates will be executed on behalf of the
      Company by its Chairman of the Board, its Chief Executive Officer, its
      Chief Operating Officer, its President, or any Vice President, either
      manually or by facsimile signature, will have affixed thereto the
      Company's seal or a facsimile thereof, and will be attested by the
      Secretary or an Assistant Secretary of the Company, either manually or by
      facsimile signature.   The Rights Certificates will be countersigned by
      the Rights Agent, either manually or by facsimile signature and will not
      be valid for any purpose unless so countersigned.   In case any officer
      of the Company who has signed any of the Rights Certificates ceases 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 Certificate may be signed on
      behalf of the Company by any Person who, at the actual date of the
      execution of such Rights Certificate, is 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 under this Agreement.   Such books will show the names and
      addresses of the respective holders of the Rights Certificates, the
      number of Rights evidenced on the face of the Rights Certificates, and
      the date of each of the Rights Certificates.

      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 7(E) and SECTION 14, at any
      time after the Distribution Date, and at or prior to the Expiration Date,
      any Rights Certificate or Certificates may be transferred, split up,
      combined, or exchanged for another Rights Certificate or Rights
      Certificates, entitling the registered holder to purchase a like number

                                       7
<PAGE>   11



      of Rights Shares (or, following a Triggering Event, preferred 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 Rights Certificates will make such request in
      writing delivered to the Rights Agent, and will surrender the Rights
      Certificate or Rights 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
      will be obligated to take any action whatsoever with respect to the
      transfer of any such surrendered Rights Certificate until the registered
      holder has completed and signed the certificate contained in the form of
      assignment on the reverse side of such Rights Certificate and has
      provided such additional evidence of the identity of the Beneficial Owner
      (or former Beneficial Owner) or Affiliates or Associates thereof as the
      Company requests in good faith.   Thereupon, the Rights Agent will,
      subject to SECTION 4, SECTION 7(E) and SECTION 14, 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 any Rights Certificate.

           (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 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), the registered holder of any Rights
      Certificate may exercise the Rights evidenced thereby (except as
      otherwise provided in this Agreement including, without limitation, the
      restrictions on exercisability set forth in SECTION 9(C), SECTION
      11(A)(III), SECTION 23(A) and SECTION 24) 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 of the Rights Certificate 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 for each
      share of Common 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) the Close of Business on August 30, 2006,
      (the "Final Expiration Date"), (ii) the time at which the Rights are
      redeemed as provided in SECTION 23 or (iii) the time at which such rights
      are exchanged as provided in SECTION 24 (the earlier of the times, the
      "Expiration Date")).

                                       8
<PAGE>   12





           (b) The Purchase Price for each share of Common Stock pursuant to
      the exercise of a Right will initially be $30.00, subject to adjustment
      from time to time as provided in SECTION 11, and SECTION 13(a).  The
      Purchase Price will be payable in accordance with SECTION 7(c).

           (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 of the Purchase Price for the shares of
      Common Stock (or other shares, securities, cash or other assets, as the
      case may be) to be purchased and an amount equal to any applicable
      transfer tax, the Rights Agent will, subject to SECTION 20(k), promptly
      (i) (A) requisition from any transfer agent of the shares of Common Stock
      (or make available, if the Rights Agent is the transfer agent for such
      shares) certificates for the total number of shares of Common Stock to be
      purchased (the Company hereby irrevocably authorizing its transfer agent
      to comply with all such requests) or (B) if the Company has elected to
      deposit the shares of Common Stock with a depository agent, requisition
      from the depository agent depository receipts representing such number of
      shares of Common Stock as are to be purchased (in which case certificates
      for the shares of Common Stock represented by such receipts will be
      deposited by the transfer agent with the depository agent) and the
      Company will direct the depository 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; (iii) after
      receipt of such certificates or depository receipts, cause such
      certificates or depository receipts 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 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)) will be made in cash or by certified bank check or bank draft
      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, or distribute other property pursuant to SECTION
      11(a), the Company will make all arrangements necessary so that such
      other securities, cash, or other property are available for distribution
      by the Rights Agent, if and when appropriate.  The Company reserves the
      right to require prior to the occurrence of a Triggering Event that, upon
      any exercise of Rights, a number of Rights be exercised so that only
      whole shares of Common Stock would be issued.

           (d) If the registered holder of any Rights Certificate exercises
      less than all the Rights evidenced by such certificate, a new Rights
      Certificate evidencing the unexercised Rights will 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.

           (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 any Person referred to in CLAUSES (I) through (III)
      below will become null and void

                                       9
<PAGE>   13



      without any further action and no holder of such Rights will have any
      rights whatsoever with respect to such Rights, under any provision of
      this Agreement or otherwise: (i) an Acquiring Person or an Associate or
      Affiliate of an Acquiring Person, (ii) a transferee from an Acquiring
      Person (or from any Associate or Affiliate of an Acquiring Person) that
      becomes a transferee after the Acquiring Person becomes such, or (iii) a
      transferee from an Acquiring Person (or of any such Associate or
      Affiliate) that 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
      or (B) a transfer that the Board of Directors of the Company has
      determined is part of an agreement, plan, arrangement, or understanding
      that has as a substantial purpose or effect the avoidance of this SECTION
      7(E).  The Company will use reasonable efforts to insure that the
      provisions of this SECTION 7(E) and SECTION 4(B) are complied with, but
      will have no liability under this Agreement 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 of its
      Affiliates, Associates, or transferees.

           (f) Notwithstanding anything in this Agreement to the contrary,
      neither the Rights Agent nor the Company will 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 has (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 the identity of the Beneficial Owner (or former
      Beneficial Owner) or Affiliates or Associates thereof as the Company
      requests in good faith.

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

      Section 9. Reservation and Availability of Capital Stock.

           (a) The Company will use its best efforts to reserve and keep
      available out of its authorized and unissued shares of Common Stock
      (and/or or other securities) or its authorized and issued shares of
      Common Stock (and/or or other securities) held in its

                                       10
<PAGE>   14



      treasury, the number of shares of Common Stock (and/or other securities)
      that will be sufficient to permit the exercise in full of all outstanding
      Rights.

           (b) So long as the shares of Common Stock (and, following the
      occurrence of a Triggering Event, Common Stock or other securities)
      issuable and deliverable upon the exercise of the Rights may be listed on
      any national securities exchange or automated quotation system, the
      Company will use its reasonable 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 or automated quotation system upon
      official notice of issuance upon such exercise.

           (c) The Company will use its best efforts to (i) file, as soon as
      practicable following 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),
      a registration statement under the Act, with respect to the securities
      purchasable upon exercise of the Rights or issued in an exchange pursuant
      to SECTION 24 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 the
      earlier of (A) the date as of which the Rights are no longer exercisable
      for such securities, and (B) the Expiration Date.  The Company will also
      take such action as may be appropriate under, or to ensure compliance
      with, the applicable state securities laws in connection with the
      exercisability of the Rights.   The Company may temporarily suspend, for
      up to 90 days after the date described in CLAUSE (I) 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 will 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 no longer remains in
      effect.  In addition, if the Company determines 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 will not be
      exercisable in any jurisdiction if the requisite qualification in such
      jurisdiction has not been obtained, the exercise of such Rights is not
      permitted under applicable law, or a registration statement has not been
      declared effective.

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

           (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
      that may be payable in respect of the issuance or delivery of the Rights
      Certificates and any Common Stock or

                                       11
<PAGE>   15



      other certificates issued upon the exercise of Rights.  The Company will
      not, however, be required to pay any transfer tax that may be payable in
      respect of any transfer or delivery of Rights Certificates to a Person
      other than, or the issuance or delivery of Common Stock (or other
      securities, as the case may be) in respect of a name other than that of
      the registered holder of the Rights Certificates or to issue or deliver
      any Common Stock or other certificates in a name other than that of the
      registered holder until such tax has 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.

      Section 10. Common Stock Record Date.   Each Person in whose name any
Rights Share certificate is issued will, for all purposes, be deemed to have
become the record holder of such Rights Shares represented thereby, and such
certificate will be dated, on 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 Common Stock (other
securities, as the case may be) transfer books of the Company are closed, such
Person will be deemed to have become the record holder of the Rights Shares on,
and such certificate will be dated, the next succeeding Business Day on which
the Common Stock (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 Rights Certificate holders will not be entitled to any stockholder rights
with respect to Rights Shares, including, without limitation, the right to
vote, to receive dividends or other distributions, or to exercise any
preemptive rights, and will not be entitled to receive any notice of any
proceedings of the Company, except as provided in this Agreement.

      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 at any time after the date of this
            Agreement (A) declares a dividend on the Common Stock payable in
            shares of Common Stock, (B) subdivides the outstanding Common
            Stock, (C) combines the outstanding Common Stock into a smaller
            number of shares, or (D) issues any shares of its capital stock in
            a reclassification of the Common Stock (including, without
            limitation, 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), 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 Common Stock or capital stock, as the
            case may be, issuable on such date, will be proportionately
            adjusted so that the holder of any Right exercised after such time
            will be entitled to receive, upon payment of the Purchase Price
            then in effect, the aggregate number and kind of shares of Common
            Stock or capital stock, as the case may be, that, if such Right had
            been exercised

                                       12

            immediately prior to such date and at a time when the Common Stock
            transfer books of the Company were open, such holder would have
            owned upon such exercise and been entitled to receive by virtue of
            such dividend, subdivision, combination, or reclassification.  If
            an event occurs that would require an adjustment under both this
            SECTION 11(a)(I) and SECTION 11(a)(II), the adjustment provided for
            in this SECTION 11(a)(I) will be in addition to, and will be made
            prior to, any adjustment required pursuant to SECTION 11(a)(II).

                 (ii) In the event that any Person, alone or together with its
            Affiliates and Associates, at any time after the Rights Dividend
            Declaration Date, becomes an Acquiring Person, then, proper
            provision will be made so that each Right holder (except as
            provided in SECTION 7(e)) will thereafter have the right to
            receive, upon exercise of such Right at the then current Purchase
            Price in accordance with the terms of this Agreement, such number
            of  Rights Shares equal to the result obtained by (x) multiplying
            the then current Purchase Price by the then number of Rights Shares
            for which a Right is then exercisable and (y) dividing that product
            by 50% of the Current Market Price (defined in SECTION 11(d)) per
            share of Common Stock on the date such Person became an Acquiring
            Person (such number of Rights Shares, the "Adjustment Shares").

                 (iii) In the event that the number of shares of Common Stock
            that are authorized by the Company's articles of incorporation but
            not issued, or issued but not outstanding, are not sufficient to
            permit the exercise in full of the Rights in accordance with
            SECTION 11(a)(II), the Company will, upon the exercise of a Right
            and payment of the applicable Purchase Price, (A) determine the
            value of the Adjustment Shares issuable upon the exercise of a
            Right (the "Current Value"), and (B) with respect to each Right
            (subject to SECTION 7(e)), make adequate provision to substitute
            for the Adjustment Shares (1) cash, (2) a reduction in the Purchase
            Price, (3) other equity securities of the Company (including,
            without limitation, shares, or units of shares, of preferred
            stock), that a Requisite Majority has deemed to have essentially
            the same rights, privileges and preferences as shares of Common
            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 conclusively determined by a Requisite
            Majority based upon the advice of a nationally recognized
            investment banking firm selected by a Requisite Majority; provided,
            however, that if the Company has not made adequate provision to
            deliver value pursuant to CLAUSE (B) above within 30 days following
            the first occurrence of a Section 11(a)(ii) Event, then the Company
            will 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 or cash have an aggregate value equal to the
            Spread.  The term "Spread" means the excess of (i) the Current
            Value over (ii) the Purchase Price.  If the Board of Directors
            determines in good faith that it is likely that sufficient
            additional shares of Common Stock could be authorized for

                                       13
<PAGE>   17



            issuance upon exercise in full of the Rights, the 30-day period set
            forth above may be extended to the extent necessary, but not more
            than 90 days after the Section 11(a)(ii) Trigger Date, in order
            that the Company may seek shareholder approval for the
            authorization of such additional shares (such 30-day period, as it
            may be extended, being the "Substitution Period").  To the extent
            that action is to be taken pursuant to this SECTION 11(a)(III), the
            Company (1) will provide, subject to SECTION 7(e), that such action
            will apply uniformly to all outstanding Rights, and (2) may suspend
            the exercisability of the Rights until the expiration of the
            Substitution Period in order to seek any required shareholder
            approval or to decide the appropriate form of distribution to be
            made and the value thereof.  In the event of any such suspension,
            the Company will 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 no
            longer remains in effect.  For purposes of this SECTION 11(A)(III),
            the Current Value of each Adjustment Share will be the Current
            Market Price per share of the Common Stock on the effective date of
            the Section 11(a)(ii) Event and the per share or per unit value of
            any Common Stock Equivalent will be deemed to equal the Current
            Market Price per share of the Common Stock on such date.

            (b) In case the Company fixes a record date for the issuance of
      rights, options or warrants to all holders of Common Stock entitling them
      to subscribe for or purchase (for a period expiring within 45 calendar
      days after such record date) Common Stock (and/or Common Stock
      Equivalents) (or securities convertible into Common Stock) at a price per
      share of Common Stock (or having a conversion price per share, if a
      security convertible into Common Stock) less than the Current Market
      Price per share of Common Stock on such record date, the Purchase Price
      to be in effect after such record date will be determined by multiplying
      the Purchase Price in effect immediately prior to such record date by a
      fraction, (i) the numerator of which is the number of shares of Common
      Stock outstanding on such record date, plus the number of shares of
      Common Stock that the aggregate offering price of the total number of
      shares of Common Stock (and/or Common Stock Equivalents) so to be offered
      (or the aggregate initial conversion price of the convertible securities
      so to be offered) would purchase at such Current Market Price, and (ii)
      the denominator of which is the number of shares of Common Stock
      outstanding on such record date, plus the number of additional shares of
      Common Stock (and/or Common Stock Equivalents) to be offered for
      subscription or purchase (or into which the convertible securities so to
      be offered are initially convertible).  In the event that the number of
      shares of Common Stock issuable under the terms of a convertible
      security, or the conversion or exercise price of such convertible
      security, changes after the initial issuance of such convertible
      security, an adjustment will be made to the Purchase Price that conforms
      with the adjustment set forth in this SECTION 11(b).  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 will be as conclusively determined in good faith by the
      Board of Directors of the Company, whose determination will be described
      in a statement filed with the Rights Agent and will be binding on the
      Rights Agent and the holders of the Rights.  Shares of Common Stock owned
      by or held for the

                                       14
<PAGE>   18



      account of the Company will be deemed not to be outstanding for the
      purpose of any such computation.  Such adjustment will 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 will be
      adjusted to be the Purchase Price that would then be in effect if such
      record date had not been fixed.

           (c) In case the Company fixes a record date for a distribution to
      all holders of Common 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 Common Stock,
      but including any dividend payable in stock other than Common Stock) or
      subscription rights or warrants (excluding those referred to in SECTION
      11(b)), the Purchase Price to be in effect after such record date will be
      determined by multiplying the Purchase Price in effect immediately prior
      to such record date by a fraction, (i) the numerator of which is the
      Current Market Price per share of Common Stock on such record date, less
      the fair market value (as conclusively determined in good faith by the
      Board of Directors of the Company, whose determination will 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 Common Stock and
      (ii) the denominator of which is such Current Market Price per share of
      Common Stock.  Such adjustments will be made successively whenever such a
      record date is fixed, and in the event that such distribution is not so
      made, the Purchase Price will be adjusted to be the Purchase Price that
      would have been in effect if such record date had not been fixed.

           (d) The "Current Market Price" per share of Common Stock on any date
      will be deemed to be the average of the daily closing prices per share of
      such Common Stock for the 30 consecutive Trading Days immediately prior
      to 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 (i) a
      dividend or distribution on such Common Stock payable in shares of such
      Common Stock or securities convertible into shares of such Common Stock
      (other than the Rights), or (ii) any subdivision, combination, or
      reclassification of such Common Stock, and the ex-dividend date for such
      dividend or distribution, or the record date for such subdivision,
      combination, or reclassification has not occurred prior to the
      commencement of the requisite 30 Trading Day period, as set forth above,
      then, and in each such case, the Current Market Price will be properly
      adjusted to take into account ex-dividend trading.  The closing price for
      each day will 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
      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

                                       15
<PAGE>   19



      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 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 of 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.  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 will be used.  If the Common Stock is not publicly
      held or not so listed or traded, Current Market Price per share will mean
      the fair value per share as determined in good faith by the Board of
      Directors, the determination of which will be described in a statement
      filed with the Rights Agent and will be conclusive for all purposes.

           (e) Anything in this Agreement to the contrary notwithstanding, no
      adjustment in the Purchase Price will 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 that by reason of
      this SECTION 11(e) are not required to be made will be carried forward
      and taken into account in any subsequent adjustment.  All calculations
      under this SECTION 11 will be made to the nearest cent or to the nearest
      one-hundredth of a share of Common Stock.  Notwithstanding the first
      sentence of this SECTION 11(e), any adjustment required by this SECTION
      11 will 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.

           (f) If, as a result of an adjustment made pursuant to SECTION
      11(A)(II) or SECTION 13(A), the holder of any Right thereafter exercised
      becomes entitled to receive any shares of capital stock other than Common
      Stock, then the number of such other shares so receivable upon exercise
      of any Right and the Purchase Price will 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 Common Stock contained in SECTIONS
      11(a), (b), (c), (e), (g), (h), (i), (j), (k), (m), and (q) and the
      provisions of SECTIONS 7, 9, 10, 13, and 14 with respect to the Common
      Stock will 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 under this Agreement will evidence
      the right to purchase, at the adjusted Purchase Price, the number of
      Rights Shares purchasable from time to time under this Agreement, all
      subject to further adjustment as provided in this Agreement.

           (h) Unless the Company has 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 will thereafter
      evidence the right to purchase, at the adjusted Purchase Price, that
      number of Rights Shares (calculated to the nearest one-hundredth)
      obtained by (i)

                                       16
<PAGE>   20



      multiplying (x) the number of Rights Shares 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 Rights Shares purchasable upon the exercise
      of a Right.  Each of the Rights outstanding after such an adjustment in
      the number of Rights will be exercisable for the number of Rights Shares
      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 will become that number of Rights (calculated to the nearest
      one-hundredth) 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 will 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, will be at
      least ten Business 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 will, 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, the additional Rights to which such holders are
      entitled as a result of such adjustment, or, at the option of the
      Company, will 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 are entitled after such adjustment.  Rights
      Certificates so to be distributed will be issued, executed, and
      countersigned in the manner provided for in this Agreement (and may bear,
      at the option of the Company, the adjusted Purchase Price) and will 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 Rights Shares, the Rights Certificates theretofore and thereafter
      issued may continue to express the Purchase Price per Rights Shares and
      the number of Rights Shares that were expressed in the initial Rights
      Certificates issued under this Agreement.

           (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
      Rights Shares, the Company will take any corporate action that may, in
      the opinion of its counsel, be necessary in order that the Company may
      validly and legally issue such number of fully paid and nonassessable
      Rights Shares at such adjusted Purchase Price.


                                       17
<PAGE>   21




           (l) In any case in which this SECTION 11 requires 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 Rights Shares and other capital stock or
      securities of the Company, if any, issuable upon such exercise over and
      above the number of Rights Shares 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 will 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 will 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 its good faith judgment, the Board of
      Directors of the Company determines it to be advisable in order that any
      (i) consolidation or subdivision of the Common Stock, (ii) issuance
      wholly for cash of any shares of Common Stock at less than the current
      market price, (iii) issuance wholly for cash of shares of Common Stock or
      securities that by their terms are convertible into or exchangeable for
      shares of Common 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 Common Stock will not be taxable to such
      stockholders.

           (n) The Company covenants and agrees that it will not, at any time
      after the Distribution Date, (i) consolidate with any other Person (other
      than a Subsidiary of the Company in a transaction that complies with
      SECTION 11(o)), (ii) merge with, from, or into any other Person (other
      than a Subsidiary of the Company in a transaction that complies with
      SECTION 11(o)), 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 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 or any of
      its Subsidiaries in one or more transactions each of which complies with
      SECTION 11(o)), if (x) at the time of or immediately after such
      consolidation, merger, or sale there are any rights, warrants, or other
      instruments or securities outstanding or agreements in effect that could
      reasonably be expected to 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, or
      sale, the stockholders of the Person that constitutes, or would
      constitute, the "Principal Party" for purposes of SECTION 13(a) has
      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 27, take
      (or permit any Subsidiary to take) any action if at the time such action
      is taken it is reasonably foreseeable that such

                                       18
<PAGE>   22



      action will diminish substantially or otherwise eliminate the benefits
      intended to be afforded by the Rights.

           (p) Notwithstanding anything in this Agreement to the contrary, in
      the event that the Company at any time after the Rights Dividend
      Declaration Date and prior to the Distribution Date (i) declares a
      dividend on the outstanding shares of Common Stock payable in shares of
      Common Stock, (ii) subdivides the outstanding shares of Common Stock, or
      (iii) combines 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, will be proportionately adjusted so that
      the number of Rights thereafter associated with each share of Common
      Stock following any such event will 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 is the total number of shares of Common Stock outstanding
      immediately prior to the occurrence of the event and the denominator of
      which is the total number of shares of Common Stock outstanding
      immediately following the occurrence of such event.

           (q) In the event that the Rights become exercisable following a
      Section 11(a)(ii) Event, the Company, by action of a Requisite Majority,
      may permit the Rights, subject to SECTION 7(e), to be exercised for 50%
      of the shares of Common Stock (or cash or other securities or assets to
      be substituted for the Adjustment Shares pursuant to SECTION 11(a)(iii))
      that would otherwise be purchasable under SECTION 11(a) in consideration
      of the surrender to the Company of the Rights so exercised and without
      other payment of the Purchase Price.  Rights exercised under this SECTION
      11(q) will be deemed to have been exercised in full and will be
      cancelled.

      Section 12. Certificate of Adjusted Purchase Price or Number of Shares.
Whenever an adjustment is made as provided in SECTION 11 or SECTION 13, the
Company will (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 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.  The Rights Agent will be fully protected in relying on any such
certificate and on any adjustment contained in such certificate.

      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, (i) the Company consolidates with, or merges
      with, or into, any other Person (other than a Subsidiary of the Company
      in a transaction that complies with SECTION 11(o)), and the Company is
      not the continuing or surviving Person of such consolidation or merger;
      (ii) any Person (other than a Subsidiary of the Company in a transaction
      that complies with SECTION 11(o)) consolidates with, or merges with, or
      into, the Company,

                                       19
<PAGE>   23



      and the Company is 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 is changed
      into or exchanged for stock or other securities of any other Person or
      cash or any other property; or (iii) the Company sells or otherwise
      transfers (or one or more of its Subsidiaries sells or otherwise
      transfers), 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)), then, and in each such case (except as contemplated by SECTION
      13(d)), proper provision will be made so that (A) each holder of a Right,
      except as provided in SECTION 7(e) or SECTION 13(e), will thereafter have
      the right to receive, upon the exercise of such Right at the then current
      Purchase Price in accordance with the terms of this Agreement, such
      number of validly authorized and issued, fully paid, nonassessable, and
      freely tradable shares of Common Stock of the Principal Party (as defined
      below), not subject to any liens, encumbrances, preemptive rights, rights
      of first refusal, or other adverse claims, as are equal to the result
      obtained by (1) multiplying the then current Purchase Price by the number
      of Rights Shares 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 Rights Shares 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 (2) dividing that product (which, following the
      first occurrence of a Section 13 Event, will be referred to as the
      "Purchase Price" for each Right and for all purposes of this Agreement)
      by 50% of the Current Market Price per share of the Common Stock of such
      Principal Party on the date of consummation of such Section 13 Event; (B)
      such Principal Party will thereafter be liable for, and will assume, by
      virtue of such Section 13 Event, all the obligations and duties of the
      Company pursuant to this Agreement; (C) the term "Company" will
      thereafter be deemed to refer to such Principal Party, it being
      specifically intended that the provisions of SECTION 11 will apply only
      to such Principal Party following the first occurrence of a Section 13
      Event; (D) such Principal Party will take such steps (including, but 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 of this Agreement will
      thereafter be applicable, as nearly as may be, in relation to its shares
      of Common Stock thereafter deliverable upon the exercise of the Rights;
      and (E) the provisions of SECTION 11(a)(ii) will be of no effect
      following the first occurrence of any Section 13 Event.

           (b) "Principal Party" means

                 (i) in the case of any transaction described in CLAUSE (i) or
            (ii) 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

                                       20
<PAGE>   24





                 (ii) in the case of any transaction described in CLAUSE (III)
            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" will refer to such
            other Person; and (2) in case such Person is a Subsidiary, directly
            or indirectly, of more than one Person, with Common Stock that is
            and has been so registered, "Principal Party" will refer to
            whichever of such Persons is the issuer of the Common Stock having
            the greatest aggregate market value.

           (c) The Company will not consummate any such consolidation, merger,
      sale, or transfer unless the Principal Party has a sufficient number of
      authorized shares of its 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 Company and
      such Principal Party have executed and delivered to the Rights Agent a
      supplemental agreement providing for the Principal Party to assume and
      perform the terms set forth in SECTIONS 13(a) and (b) and further
      providing that, as soon as practicable after the date of any
      consolidation, merger, or transfer mentioned in SECTION 13(a), the
      Principal Party will

                 (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 (B) remain
            effective (with a prospectus at all times meeting the requirements
            of the Act) until the Final Expiration Date; and

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


           (d) In the event that the Rights become exercisable under SECTION
      13(a), the Company, by action of a Requisite Majority, may agree with the
      Principal Party that the Principal Party may permit the Rights to be
      exercised for 50% of the Common Shares of the Principal Party that would
      otherwise be purchasable under SECTION 13(a), in consideration of the
      surrender to the Principal Party, as the successor to the Company under
      SECTION 13(a)(ii), of the Rights so exercised and without other payment
      of the

                                       21
<PAGE>   25



      Purchase Price.  Rights exercised under this SECTION 13(e) will be deemed
      to have been exercised in full and cancelled.

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

      Section 14. Fractional Rights and Fractional Shares.

           (a) The Company will not be required to issue fractions of Rights,
      except prior to the Distribution Date as provided in SECTION 11(p), or to
      distribute Rights Certificates that evidence fractional Rights.  In lieu
      of such fractional Rights, there will 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 will 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 will 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 Company.  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 conclusively determined in good faith by the
      Board of Directors of the Company will be used.

           (b) The Company will not be required to issue fractions of shares of
      Common Stock upon exercise of the Rights or to distribute certificates
      that 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 provided in
      this Agreement an amount in cash equal to the same fraction of the
      Current Market Price of one share of Common Stock as of the Trading Day
      immediately prior to the date of such exercise.


                                       22
<PAGE>   26




           (c) The holder of a Right, by the acceptance of the Rights,
      expressly waives the 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 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, on its own behalf and for its
own benefit, enforce, and may institute and maintain any suit, action, or
proceeding against the Company to enforce, or otherwise act in respect of, its
right to exercise the Rights evidenced by such Rights Certificate in the manner
provided in such 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 will be entitled to specific
performance of the obligations under this Agreement and injunctive relief
against actual or threatened violations of the obligations under this Agreement
of any Person subject to this Agreement.

      Section 16. Agreement of Rights Holders.  Every holder of a Right by
accepting the Rights consents and agrees with the Company and the Rights Agent
and with every other holder of a Right that:

           (a) prior to the Distribution Date, the Rights will be transferable
      only in connection with the transfer of Common Stock;

           (b) after the Distribution Date, the Rights Certificates are
      transferable only on the registry books of the Rights Agent if
      surrendered at the principal office or offices of the Rights Agent
      designated for such purposes, duly endorsed or accompanied by a proper
      instrument of transfer, and with the appropriate forms and certificates
      fully executed;

           (c) subject to SECTION 6(a) and SECTION 7(f), the Company and the
      Rights Agent may deem and treat the person in whose name a Rights
      Certificate (or, prior to the Distribution Date, the associated Common
      Stock certificate) is registered as the absolute owner of the Rights
      evidenced thereby (notwithstanding any notations of ownership or writing
      on the Rights Certificates or the associated Common Stock certificate
      made by anyone other than the Company or the Rights Agent) for all
      purposes whatsoever, and neither the Company nor the Rights Agent, will
      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 will 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

                                       23
<PAGE>   27



      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 will use its reasonable best
      efforts to have any such order, decree, or ruling lifted or otherwise
      overturned as soon as possible.

      Section 17. Rights Certificate Holder Not Deemed a Stockholder.  No
holder, as such, of any Rights Certificate will be entitled to vote or receive
dividends or be deemed for any purpose the holder of the number of shares of
Common Stock or any other securities of the Company that may at any time be
issuable on the exercise of the Rights represented thereby, nor will anything
contained in this Agreement or in any Rights Certificate be construed to confer
upon the holder of any Rights Certificate, as such, any of the rights of a
stockholder of the Company or any right to vote for the election of directors
or upon any matter submitted to stockholders, 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 25), or to receive
dividends or subscription rights, or otherwise, until the Right or Rights
evidenced by such Rights Certificate have been exercised in accordance with the
provisions of this Agreement.

      Section 18. Concerning the Rights Agent.

           (a) The Company agrees to pay to the Rights Agent reasonable
      compensation for all services rendered by it under this Agreement 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 under this Agreement.  The Company also agrees
      to indemnify the Rights Agent for, and to hold it harmless against, any
      loss, liability, or expense, incurred without gross negligence, bad
      faith, or willful misconduct on the part of the Rights Agent, for
      anything done or omitted to be done 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.

           (b) The Rights Agent will be protected and will 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 document 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 Person into or with which the Rights Agent or any successor
      Rights Agent may be merged or with which it may be consolidated, or any
      Person resulting from

                                       24
<PAGE>   28



      any merger or consolidation to which the Rights Agent or any successor
      Rights Agent is a party, or any corporation succeeding to the corporate
      trust or shareholder services business of the Rights Agent or any
      successor Rights Agent, will 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 to this Agreement;
      provided, however, that such corporation would be eligible for
      appointment as a successor Rights Agent under the provisions of SECTION
      21.  In case at the time such successor Rights Agent succeeds to the
      agency created by this Agreement, any of the Rights Certificates 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 have not 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 will have the full force provided in the
      Rights Certificates and in this Agreement.

           (b) In case at any time the name of the Rights Agent is changed and
      at such time any of the Rights Certificates have been countersigned but
      not delivered, the Rights Agent may adopt the countersignature under its
      prior name and deliver Rights Certificates so countersigned; and in case
      at that time any of the Rights Certificates have not been countersigned,
      the Rights Agent may countersign such Rights Certificates either in its
      prior name or in its changed name, and in all such cases such Rights
      Certificates will 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 of such Rights Certificates, will 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 will 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 deems 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
      under this Agreement, such fact or matter (unless other evidence in
      respect of such fact or matter is specifically prescribed in this
      Agreement) may be deemed to be conclusively proved and established by a
      certificate signed by the Chairman of the Board, the Chief Executive
      Officer, the Chief Operating 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
      certificate will be

                                       25
<PAGE>   29



      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.

           (c) The Rights Agent will be liable under this Agreement only for
      its own gross negligence, bad faith or willful misconduct.

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

           (e) The Rights Agent will not be under any responsibility in respect
      of the validity of this Agreement or the execution and delivery of this
      Agreement (except the due execution of this Agreement by the Rights
      Agent) or in respect of the validity or execution of any Rights
      Certificate (except its countersignature); nor will it be responsible for
      any breach by the Company of any covenant or condition contained in this
      Agreement or in any Rights Certificate; nor will it be responsible for
      any adjustment required under the provisions of SECTION 11 or SECTION 13,
      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 actual notice of any such adjustment); nor will
      it by any act under this Agreement be deemed to make any representation
      or warranty as to the authorization or reservation of any shares of
      Common Stock to be issued pursuant to this Agreement or any Rights
      Certificate or as to whether any shares of Common Stock will, when so
      issued, be validly authorized or issued, fully paid, or nonassessable.

           (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.

           (g) The Rights Agent is hereby authorized and directed to accept
      instructions with respect to the performance of its duties under this
      Agreement from the Chairman of the Board, the Chief Executive Officer,
      the Chief Operating Officer, the President, any Vice President, the
      Secretary, any Assistant Secretary, the Treasurer, or any Assistant
      Treasurer of the Company, and to apply to such officers for advice or
      instructions in connection with its duties, and it will not be liable for
      any action taken or suffered to be taken by it in good faith in
      accordance with instructions of any such officer.

           (h) The Rights Agent and any stockholder, director, officer, or
      employee of the Rights Agent may buy, sell, or deal in any of the Rights
      or other securities of the Company or become pecuniarily interested in
      any transaction in which the Company may be interested, contract with or
      lend money to the Company, or otherwise act as fully and

                                       26
<PAGE>   30



      freely as though it were not Rights Agent under this Agreement.  Nothing
      in this Agreement will preclude the Rights Agent from acting in any other
      capacity for the Company or for any other Person.

           (i) The Rights Agent may execute and exercise any of the rights or
      powers vested by this Agreement in it or perform any duty under this
      Agreement either itself or by or through its attorneys or agents, and the
      Rights Agent will 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 of such Person.

           (j) No provision of this Agreement will 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 under this Agreement or in the
      exercise of its rights if there are 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 been completed or indicates an affirmative response to
      clause 1 or 2 of such certificate, the Rights Agent will 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 30 days' notice in writing mailed to the Company, and to each transfer
agent of the Common 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 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, by registered or certified mail,
and to the holders of the Rights Certificates by first-class mail.  If the
Rights Agent resigns or is removed or otherwise becomes incapable of acting,
the Company will appoint a successor to the Rights Agent.  If the Company fails
to make such appointment within a period of 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 holder of a
Rights Certificate (who will, with such notice, submit such holder's 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, will be a corporation organized
and doing business under the laws of the United States or a State of the United
States, in good standing, that is authorized under such laws to exercise
corporate trust powers and is subject to supervision or examination by federal
or state authority and that has at the time of its appointment as Rights Agent
a combined capital and surplus of at least $25,000,000.  After appointment, the
successor Rights Agent will

                                       27
<PAGE>   31



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, except
that the predecessor Rights Agent will deliver and transfer to the successor
Rights Agent any property at the time held by it under this Agreement 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 will file notice of such appointment in writing with the
predecessor Rights Agent and each transfer agent of the Common Stock and the
Common Stock, and mail a notice of such appointment 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 in such notice, will
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, in its discretion, 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, 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 Expiration Date, the Company (a) will, 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, granted or awarded as of the
Distribution Date, or upon the exercise, conversion, or exchange of securities
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 (y) no such Rights Certificate will be issued
if, and to the extent that, the Company is advised by counsel that such
issuance would create a significant risk of material adverse tax consequences
to the Company or the Person to whom such Rights Certificate would be issued,
and (z) no such Rights Certificate will be issued if, and to the extent that,
appropriate adjustment has otherwise been made in lieu of the issuance of such
Rights Certificate.

      Section 23. Redemption and Termination.

           (a) The Company may, at its option, by action of a Requisite
      Majority, at any time prior to the earlier of (i) such time as a Person
      becomes an Acquiring Person, or (ii) the Final Expiration Date, redeem
      all but not fewer than all the then outstanding Rights at the Redemption
      Price (the date of such redemption, the "Redemption Date"), and the
      Company, at its option, may pay the Redemption Price either in cash or
      Common Stock or other securities of the Company, deemed by the Board of
      Directors, in the exercise of its sole discretion, to be at least
      equivalent in value to the Redemption Price.

           (b) Immediately upon the action of a Requisite Majority ordering the
      redemption of the Rights, evidence of which has 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 holders of Rights will be to receive the

                                       28
<PAGE>   32



      Redemption Price.  Promptly after the action of a Requisite Majority
      ordering the redemption of the Rights, the Company will give notice of
      such redemption to the Rights Agent and to 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 Rights
      Agent or, prior to the Distribution Date, on the registry books of the
      transfer agent for the Common Stock.  Each such notice of redemption will
      state the method by which the payment of the Redemption Price will be
      made.  Any notice that is mailed in the manner in this Agreement provided
      will be deemed given, whether or not the holder receives such notice.  In
      any case, failure to give such notice by mail, or any defect in the
      notice, to any particular holder of Rights shall not affect the
      sufficiency of the notice to other holders of Rights.

      Section 24. Exchange.

           (a) The Board of Directors of the Company may, at its option, at any
      time after a Triggering Event, exchange all or part of the then
      outstanding and exercisable Rights (which will not include Rights that
      have become void pursuant to the provisions of SECTION 7(E) hereof) for
      shares of Common Stock, each Right being exchangeable for one share of
      Common Stock, appropriately adjusted to reflect any transaction specified
      in SECTION 11(A)(I) occurring after the Record Date (such number of
      shares of Common Stock issuable in exchange for one Right being referred
      to herein as the "Exchange Shares").  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 of its
      Subsidiaries or any Person or entity organized, appointed or established
      by the Company for or pursuant to the terms of any such Plan), together
      with all Affiliates and Associates of such Person, becomes the Beneficial
      Owner of 50% or more of the Common Stock then outstanding.

           (b) Immediately upon the action of the Board of Directors of the
      Company ordering the exchange of any Rights pursuant to subsection (a) of
      this SECTION 24 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 the Exchange
      Shares.  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
      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 that 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 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.


                                       29
<PAGE>   33




           (c) In the event that there shall not be sufficient Common Stock
      issued but not outstanding, or authorized but unissued, to permit any
      exchange of Rights as contemplated in accordance with this SECTION 24,
      the Company shall take all such action as may be necessary to authorize
      additional Common Stock for issuance upon exchange of the Rights or shall
      take such other action specified in SECTION 11(A)(III) hereof.

           (d) The Company shall not be required to issue fractions of shares
      of Common Stock to distribute certificates which evidence fractional
      Common Stock.  In lieu of such fractional shares, the Company shall pay
      to the registered holders of the Right Certificates with regard to which
      such fractional shares would otherwise be issuable an amount in cash
      equal to the same fraction of the Current Market Price of a whole share
      of Common Stock.  For the purposes of this SUBSECTION (D), the Current
      Market Value of a whole share of Common Stock shall be determined as of
      the Trading Day immediately prior to the date of exchange pursuant to
      this SECTION 24.

      Section 25. Notice of Certain Events.

           (a) In case the Company proposes, at any time after the Distribution
      Date, (i) to pay any dividend payable in stock of any class to the
      holders of Common Stock or to make any other distribution to the holders
      of Common Stock (other than a regular quarterly cash dividend out of
      earnings or retained earnings of the Company), or (ii) to offer to the
      holders of Common Stock rights or warrants to subscribe for or to
      purchase any additional shares of Common Stock or shares of stock of any
      class or any other securities, rights or options, or (iii) to effect any
      reclassification of its Common Stock (other than a reclassification
      involving only the subdivision of outstanding shares of Common 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 that complies
      with SECTION 11(O)), 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 or any of its Subsidiaries in one or more transactions
      each of which complies with SECTION 11(O)), or (v) to effect the
      liquidation, dissolution or winding up of the Company, then, in each such
      case, the Company will give to each holder of a Rights Certificate, to
      the extent feasible and in accordance with SECTION 26, a notice of such
      proposed action, which will 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 Common Stock, if
      any such date is to be fixed, and such notice will be so given in the
      case of any action covered by CLAUSE (I) or (II) above at least 20 days
      prior to the record date for determining holders of the shares of Common
      Stock for purposes of such action, and in the case of any such other
      action, at least 20 days prior to the date of the taking of such proposed
      action or the date of participation therein by the holders of the shares
      of Common Stock, whichever is the earlier.

           (b) In case of a Triggering Event, then (i) the Company will as soon
      as practicable give to each holder of a Rights Certificate, to the extent
      feasible and in accordance with SECTION 26, a notice of the occurrence of
      such event, which will specify the event and the consequences of the
      event to holders of Rights under this Agreement, and (ii) all references
      in SECTION 25(A) to Common Stock will be deemed thereafter to refer to
      other securities, if appropriate.

      Section 26. Notices.  Notices or demands authorized by this Agreement to

make any other provisions in regard to matters or questions arising under this
Agreement that the Company and Rights Agent may deem necessary or desirable and
that will be consistent with, and for the purpose of fulfilling, the objectives
of the Board of Directors in adopting this Agreement; provided, however, that
following the Stock Acquisition Date, this Agreement shall not be amended in
any manner that would adversely affect the basic economic terms of the Rights;
provided, further, that, once the Rights are no longer redeemable in accordance
with SECTION 23 of this Agreement, no amendment to this Agreement may have the
effect of making the Rights redeemable.

      Section 28. Successors.  All the covenants and provisions of this
Agreement by or for the benefit of the Company or the Rights Agent will bind
and inure to the benefit of their respective successors and assigns under this
Agreement.

      Section 29. Determinations and Actions by the Board of Directors, etc.
For all purposes of this Agreement, any calculation of the number of shares of
Common Stock outstanding at any particular time, including for purposes of
determining the particular percentage of such outstanding shares of Common

exclusive power and authority to administer this Agreement and to exercise all
rights and powers specifically granted to the Board of Directors (with, where
specifically provided for in this Agreement, the concurrence of the Continuing
Directors) or to the Company, or as may be necessary or advisable in the
administration of this Agreement, including, without limitation, the right and
power to (a) interpret the provisions of this Agreement, and (b) make all
determinations deemed necessary or advisable for the administration of this
Agreement (including, without limitation, a determination to redeem or not
redeem the Rights or to amend the Agreement).  All such actions, calculations,
interpretations and determinations (including, for purposes of CLAUSE (Y)
below, all omissions with respect to the foregoing) that are done or made by

Agreement, the concurrence of the Continuing Directors) in good faith, will (x)
be final, conclusive, and binding on the Company, the Rights Agent, the holders
of the Rights, and all other parties, and (y) not subject the Board of
Directors or the Continuing Directors to any liability to the holders of the
Rights.

      Section 31. Severability.  If any term, provision, covenant, or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void, or unenforceable, the remainder of the
terms, provisions, covenants, and restrictions of this Agreement will remain in
full force and effect and will in no way be affected, impaired, or invalidated;
provided, however, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant, or restriction is held by such
court or authority to be invalid, void, or unenforceable and the Board of
Directors of the Company determines in its good faith judgment that severing
the invalid language from this Agreement would adversely affect the purpose or
effect of this Agreement, the right of redemption set forth in SECTION 23 will
be reinstated and will not expire until the Close of Business on the tenth
Business Day following the date of such determination by the Board of
Directors.  Without limiting the foregoing, if any provision requiring action
by a Requisite Majority is held by any court of competent jurisdiction or other
authority to be invalid, void, or unenforceable, such determination will then
be made by the Board of Directors of the Company in accordance with applicable
law and the Company's articles of incorporation and by-laws.

                                ________ Rights

      NOT EXERCISABLE AFTER __________________, 2006 OR EARLIER IF REDEEMED BY
THE COMPANY.  THE RIGHTS ARE SUBJECT TO REDEMPTION, AT THE OPTION OF THE
COMPANY, AT $0.01 PER RIGHT ON THE TERMS SET FORTH IN THE RIGHTS AGREEMENT.
UNDER CERTAIN CIRCUMSTANCES, RIGHTS BENEFICIALLY OWNED BY AN ACQUIRING PERSON
(AS SUCH TERMS ARE DEFINED IN THE RIGHTS AGREEMENT) AND ANY SUBSEQUENT HOLDER
OF SUCH RIGHTS MAY BECOME NULL AND VOID.

                                Rights Certificate

                                QUEST MEDICAL, INC.

      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 August 30, 1996 (as amended from time to
time, the "Rights Agreement"), between Quest Medical, Inc., a Texas corporation
(the "Company"), and KeyCorp Shareholder Services, Inc. (the "Rights Agent"),
to purchase from the Company at any time prior to 5:00 p.m. (Dallas, Texas
time) on August 30, 2006 at the office or offices of the Rights Agent
designated for such purpose, or its successors as Rights Agent, one fully paid,
nonassessable share of Common Stock (the "Common Stock") of the Company, at a
purchase price of $30.00 per share (the "Purchase Price"), upon presentation
and surrender of this Rights Certificate with the Form of Election to Purchase
and related Certificate duly executed.  The number of Rights evidenced by this
Rights Certificate (and the number of shares that may be purchased upon
exercise thereof) set forth above, and the Purchase Price per share set forth
above, are the number and Purchase Price as of August 30, 1996 based on the
Common Stock as constituted at such date.  As provided in the Rights Agreement,
the Purchase Price and the number and kind of shares of Common Stock or other
securities, that may be purchased upon the exercise of the Rights evidenced by
this Rights Certificate are subject to modification and adjustment upon the
happening of certain events.

      This Rights Certificate is subject to all of the terms, provisions, and
conditions of the Rights Agreement, which terms, provisions, and conditions are
incorporated herein by reference and made a part of this certificate 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 Company, and the holders of the Rights Certificates,
which limitations of rights include the temporary suspension of the
exercisability of such Rights under the certain circumstances set forth in the
Rights Agreement.  Copies of the Rights Agreement are on file at

                                       1
<PAGE>   39



the above-mentioned office of the Rights Agent and are also available upon
written request to the Rights Agent.  All capitalized terms not otherwise
defined have the meaning set forth in the Rights Agreement.

      Upon the occurrence of a Section 11(a)(ii) Event, if the Rights evidenced
by this Rights Certificate are beneficially owned by (i) an Acquiring Person or
an Affiliate or Associate of any such Acquiring Person, (ii) a transferee of
any such Acquiring Person, Associate, or Affiliate, or (iii) under certain
circumstances specified in the Rights Agreement, a transferee of a Person who,
after such transfer, became an Acquiring Person or an Affiliate or Associate of
an Acquiring Person, such Rights will become null and void and no holder of
this certificate will have any right with respect to such Rights from and after
the occurrence of such Section 11(a)(ii) Event.

      This Rights Certificate, with or without other Rights Certificates, upon
surrender at the principal office or offices of the Rights Agent designated for
such purpose, may be exchanged for another Rights Certificate or Rights
Certificates of like tenor and date evidencing Rights entitling the holder to
purchase a like aggregate number of shares of Common Stock as the Rights
evidenced by the Rights Certificate or Rights Certificates surrendered have
entitled such holder to purchase.  If this Rights Certificate is exercised in
part, the holder will be entitled to receive upon surrender of this certificate
another Rights Certificate or Rights Certificates for the number of whole
Rights not exercised.

      Subject to the provisions of the Rights Agreement, the Rights evidenced by
this Certificate may be redeemed by the Company at its option at a redemption
price of $0.01 per Right.  In addition, in certain circumstances the Rights may
be exchanged, in whole or in part, for shares of the Common Stock.  Immediately
upon the action of the Board of Directors of the Company authorizing any such
exchange, and without any further action or any notice, the Rights (other than
Rights that are not subject to such exchange) will terminate and the Rights
will only enable holders to receive the shares issuable upon such exchange.
Under certain circumstances set forth in the Rights Agreement, the decision to
redeem the Rights will require the concurrence of a majority of the Continuing
Directors.

      No fractional shares of Common Stock will be issued upon the exercise of
any Right or Rights evidenced hereby, but in lieu thereof a cash payment will
be made, as provided in the Rights Agreement.

      No holder of this Rights Certificate will be entitled to vote or receive
dividends or be deemed for any purpose the holder of shares of Common Stock or
of any other securities of the Company that may at any time be issuable on the
exercise hereof, nor will anything contained in the Rights Agreement or herein
be construed to confer upon the holder of this certificate, as such, any of the
rights of a stockholder of the Company 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 the
Rights Agreement), or to receive dividends or subscription rights, or
otherwise, until the Right or Rights evidenced by this Rights Certificate have
been exercised as provided in the Rights Agreement.

                                       2

                QUEST MEDICAL, INC. REDEEMS OUTSTANDING RIGHTS;
                      ADOPTS NEW SHAREHOLDERS' RIGHTS PLAN

DALLAS, AUGUST 30, 1996-QUEST MEDICAL, INC. (NASDAQ: QMED) announced today that
its Board of Directors has voted to redeem the outstanding rights issued under
the Shareholders' Rights Plan adopted in 1989, at the pre-established
redemption price of 1 cent per right, and has adopted a new Shareholders'
Rights Plan in which Rights to purchase shares of Quest Medical's Common Stock
will be distributed as a dividend, one Right per share, to record owners of
Quest Medical's Common Stock as of the close of business on September 12, 1996.
The Shareholders' Rights Plan was not adopted in response to any known offers
for Quest Medical, Inc.

     Quest Medical's Board of Directors noted in a letter to shareholders that
the action was being taken to replace the old plan, which was already scheduled
to expire in 1999 and to implement a number of innovators that have developed
over the last several years to ensure that the plan would have its intended
effect of enhancing shareholder value.  The new Plan is designed to require
that any potential acquirer seeking to obtain control of Quest Medical treat
all Quest Medical shareholders fairly and equally and to deter the use of
coercive takeover tactics.

     "The Board has been considering adopting a new plan for several weeks,"
said Chairman Richard A. Gilleland.  Just recently, a Quest Medical shareholder
urged the Board to put the company up for sale or seek a merger partner.  The
Board has since stated publicly that the company is not for sale.

     "In the event of an unsolicited offer," Gilleland added, "the Board
believes that the new Plan will enable it to take the necessary time to
evaluate the proposal and to make sure that shareholder value is enhanced.  The
Board is not aware of any actual effort to acquire control of Quest Medical and
the new Plan is not being adopted in response to the shareholder's
recommendation or any other specific event.  We believe that the current market
and economic environment make the redemption of the existing rights and the
adoption of the new Plan prudent steps to take at this time."

     Upon becoming exercisable, each Right entitles holders to purchase one
share of Common Stock for $30.00.  The rights are not exercisable, however,
until a person or group acquires more than 15 percent of Quest Medical's common
stock or announces a tender or exchange offer for more than 20 percent of the
stock.  The purchase price and number of shares purchasable will be adjusted if
a person or group acquires more than 15 percent of Quest Medical's common
stock.

     Details of the Plan and the Rights are outlined in a letter that is being
mailed to all Quest Medical shareholders.

                                August 30, 1995



Dear Shareholder:

     Your Board of Directors has voted to redeem the outstanding rights issued
under the Shareholder's Rights Plan adopted in 1989, and has adopted a new
shareholders' rights plan.  You will be receiving a check for the redemption of
your existing rights at $0.01 per right (or for each share of Quest Medical,
Inc. Common Stock) you beneficially owned at September 12, 1996 (the "Record
Date").  The payment of the redemption price will occur on September 27, 1997.
In addition, the Board has approved a dividend distribution of one new Common
Stock purchase right (a "Right") for each share of Quest Medical Common Stock
outstanding as of the Record Date.  Under the new plan, each shareholder of
record as of that date will receive one Right for each share of Common Stock
held.  Initially, the Rights will not be exercisable and will automatically
trade with the Common Stock.  Therefore, separate Rights certificates will not
be sent to you at this time.

     Upon becoming exercisable, each Right entitles the holder to purchase one
share of Quest Medical Common Stock for $30.00.  The plan and the Rights are
described in more detail in the attached Summary of Rights to Purchase Shares
of Quest Medical, Inc. Common Stock.

     Your Board of Directors is taking these actions to replace the old plan
(which was already scheduled to expire in 1999) to implement a number of
innovations that have developed over the last several years to ensure that the
plan will have its intended effect of enhancing shareholder value.  Under the
old plan, the rights gave shareholders the ability to purchase only one-half of
a share of the Company's Common Stock, and thus provided less protection from a
coercive takeover effort.  Other aspects of the old plan were, in the Board's
judgment, outmoded or outdated.  Your Board of Directors has designed the new
Plan to require that any potential acquirer seeking to obtain control of Quest
Medical treat all Quest Medical shareholders fairly and equally and to deter
the use of coercive takeover tactics.

     The Board has been considering adopting a new plan for several weeks.
Just recently, a Quest Medical shareholder urged the Board to put the company
up for sale or seek a merger partner.  The Board has since stated publicly that
the Company is not for sale.  In the event of an unsolicited offer, however,
the Board believes that the new Plan will enable it to take the necessary time
to evaluate the proposal and to make sure that shareholder value is enhanced.
The Board is not aware of any actual effort to acquire control of Quest Medical
and the new Plan is not being adopted in response to the shareholder's
recommendation or any other specific event.  We believe that the current market
and economic environment make the redemption of the existing rights and the
adoption of the new Plan prudent steps to take at this time.

     The new Plan and the Rights will not in any way affect Quest Medical's
financial strength or interfere with its ongoing business plans.  The dividend
of the new Rights are not currently taxable to Quest Medical or its
shareholders.  The distribution will not dilute your holdings or Quest
Medical's reported earnings per share in any manner, nor will it change the way
Quest Medical's Common Stock is traded.

     The Board of Directors firmly believes the shareholders' rights plan is in
the best interest of Quest Medical and its shareholders.  If you have any
questions, we invite you to call Mr. F. Robert Merrill III at (214) 390-9800
ext. 204.


                                        Sincerely,

                                                             to Rights Agreement

                        SUMMARY OF RIGHTS TO PURCHASE
                 SHARES OF QUEST MEDICAL, INC. COMMON STOCK


     On August 26, 1996, the Board of Directors of Quest Medical, Inc. (the
"Company") declared a dividend of one common share purchase right (a "Right")
for each outstanding share of common stock, $0.05 par value (the "Common
Shares"), of the Company.  The dividend was made to the shareholders of record
at the close of business on September 12, 1996 (the "Record Date").  Each Right
entitles the registered holder to purchase from the Company one share of Common
Stock, par value $0.05 per share (the "Common Shares"), of the Company, at a
price of $30.00 (the "Purchase Price"), subject to adjustment.  The description
and terms of the Rights are set forth in a Rights Agreement dated as of August
30, 1996 (the "Rights Agreement") between the Company and KeyCorp Shareholder
Services, Inc. as Rights Agent (the "Rights Agent").

     Until the earlier to occur of (i) ten Business Days following a public
announcement that a person or group of affiliated or associated persons has
acquired, or obtained the right to acquire, beneficial ownership of 15% or more
of the outstanding Common Shares (an "Acquiring Person") or (ii) ten Business
Days following the commencement of, or announcement of an intention to make, a
tender offer or exchange offer, the consummation of which would result in the
beneficial ownership by a person or group of 20% or more of such outstanding
Common Shares (the earlier of such dates being the "Distribution Date"), the
Rights will be evidenced, with respect to any of the Common Share certificates
outstanding as of the Record Date, by such Common Share certificate with a copy
of this Summary of Rights attached to the certificate.

     The Rights Agreement provides that, until the Distribution Date, the
Rights will be transferred with and only with the Common Shares.  Until the
Distribution Date (or earlier redemption or expiration of the Rights), new
Common Share certificates issued after the Record Date upon transfer or new
issuance of Common Shares 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
Common Shares outstanding even without such notation or a copy of this Summary
of Rights being attached to such Certificate, will also constitute the transfer
of the Rights associated with the Common Shares represented by such
certificate.  As soon as practicable following the Distribution Date, separate
certificates evidencing the Rights (the "Right Certificates") will be mailed to
holders of record of the Common Shares as of the close of business on the
Distribution Date and such separate Right Certificates alone will evidence the
Rights.

     The Rights are not exercisable until the Distribution Date.  The Rights
will expire on September 12, 2006 (the "Final Expiration Date"), unless the
Final Expiration Date is extended or unless the Rights are earlier redeemed by
the Company, in each case, as described below.

     The Purchase Price payable and the number of Common Shares or other
securities or property 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 Common
Shares, (ii) upon the grant to holders of the Common Shares of certain rights
or warrants to subscribe for or purchase Common Shares at a price or securities
convertible into Common Shares with a conversion price less than the then
current market price of the Common Shares; or (iii) upon the distribution to
holders of the Common Shares of evidences of indebtedness or assets or of
subscription rights or warrants (other than those referred to above).

     In the event that any person or entity becomes an Acquiring Person (the
beneficial owner of 15% or more of the Common Shares), provision will be made
so that each holder of a Right, other than Rights


<PAGE>   4

beneficially owned by the Acquiring Person (which will then be void), will have
the right to  receive upon exercise that number of Common Shares having a
market value of two times the applicable exercise price of the Right.

     The Rights Agreement excludes from the definition of Acquiring Person,
Persons who certify to the Company that they inadvertently acquired in excess
of 14.9% of the outstanding Common Shares and thereafter divest such excess
Common Shares or who acquire 15% or more of the Common Shares in a Permitted
Transaction.  A "Permitted Transaction" is a stock acquisition or tender or
exchange offer pursuant to a definitive agreement which would result in a
person beneficially owning 15% or more of the Common Shares and which has been
approved by the Board of Directors (including a majority of the Directors not
in association with an Acquiring Person) prior to the execution of the
agreement or the public announcement of the offer.

     In the event that the Company is acquired in a merger or other business
combination transaction, or 50% or more of its consolidated assets or earning
power are sold, proper provisions will be made so that each holder of a Right
will have the right to receive, upon the exercise of the Right at the then
applicable exercise price, that number of shares of common stock of the
acquiring company that at the time of such transaction will have a market value
of two times the applicable exercise price of the Right.

     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.  No fractional Common Shares will be issued and, in lieu
of such fractional shares, an adjustment in cash will be made based on the
market price of the Common Shares on the last trading day prior to the date of
exercise.

     After a person becomes an Acquiring Person, the Company's Board of
Directors may exchange the Rights, other than those Rights owned by the
Acquiring Person, in whole or in part, at an exchange ratio of one share of
Common Stock per Right, subject to adjustment.  However, the Board of Directors
cannot conduct an exchange at any time after any Person, together with its
Affiliates and Associates, becomes the Beneficial Owner of 50% or more of the
outstanding Common Stock.

     At any time prior to any Person becoming an Acquiring Person, a Requisite
Majority may redeem the Rights in whole, but not in part, at a price of $0.01
per Right (the "Redemption Price").  In addition, the Board of Directors may
extend or reduce the period during which the Rights are redeemable, so long as
the Rights are redeemable at the time of such extension or reduction.
Immediately upon any redemption of the Rights, the right to exercise the Rights
will terminate and the only right of the holders of Rights will be to receive
the Redemption Price.

     The terms of the Rights may be amended by the Board of Directors of the
Company without the consent of the holders of the Rights, including an
amendment to extend the Final Expiration Date, except that from and after the
date any Person becomes an Acquiring Person, no such amendment may adversely
affect the economic interests of the holders of the Rights.

     Until a Right is exercised, the holder of the Right, as such, will have no
rights as a shareholder of the Company, including, without limitation, the
right to vote, or to receive dividends.
