Item 1.  Description of Securities to be Registered.

            On July 16, 1997, the Board of Directors of the
Company declared a dividend of one Preferred Stock Purchase Right (the
"Right(s)") for each outstanding share of Common Stock, par value $0.10 per
share (the "Common Stock"), of the Company. The dividend is payable as of July
28, 1997 to stockholders of record on that date. Each Right entitles the
registered holder to purchase from the Company one one-hundredth (1/100) of a
share of a new series of preferred shares of the Company, designated as Series B
Junior Preferred Stock ("Preferred Stock"), at a price of $200.00 per one
one-hundredth (1/100) of a share (the "Exercise Price"), subject to certain
adjustments. The description and terms of the Rights are set forth in a Rights
Agreement (the "Rights Agreement") between the Company and American Stock
Transfer & Trust Company, as Rights Agent ("Rights Agent"), dated as of July 16,
1997.

            Initially the Rights will not be exercisable, certificates will not
be sent to stockholders, and the Rights will automatically trade with the Common
Stock.

            The Rights, unless earlier redeemed by the Board of Directors,
become exercisable upon the close of business on the day (the "Distribution
Date") which is the earlier of (i) the tenth day following a public announcement
that a



                                  2
<PAGE>
person or group of affiliated or associated persons, with certain exceptions set
forth below, has acquired beneficial ownership of 15% or more of the outstanding
voting stock of the Company (an "Acquiring Person") and (ii) the tenth business
day (or such later date as may be determined by the Board of Directors prior to
such time as any person or group of affiliated or associated persons becomes an
Acquiring Person) after the date of the commencement or announcement of a
person's or group's intention to commence a tender or exchange offer the
consummation of which would result in the ownership of 15% or more of the
Company's outstanding voting stock (even if no shares are actually purchased
pursuant to such offer); prior thereto, the Rights would not be exercisable,
would not be represented by a separate certificate, and would not be
transferable apart from the Company's Common Stock, but will instead be
evidenced, with respect to any of the Common Stock certificates outstanding as
of July 28, 1997, by such Common Stock certificate with a copy of this Summary
of Rights attached thereto. An Acquiring Person does not include (A) the
Company, (B) any subsidiary of the Company, (C) any employee benefit plan or
employee stock plan of the Company or of any subsidiary of the Company, or any
trust or other entity organized, appointed, established or holding Common Stock
for or



                                  3
<PAGE>
pursuant to the terms of any such plan or (D) any person or group whose
ownership of 15% or more of the shares of voting stock of the Company then
outstanding results solely from (i) any action or transaction or transactions
approved by the Board of Directors before such person or group became an
Acquiring Person or (ii) a reduction in the number of issued and outstanding
shares of voting stock of the Company pursuant to a transaction or transactions
approved by the Board of Directors (provided that any person or group that does
not become an Acquiring Person by reason of clause (i) or (ii) above shall
become an Acquiring Person upon acquisition of an additional 1% of the Company's
voting stock unless such acquisition of additional voting stock will not result
in such person or group becoming an Acquiring Person by reason of such clause
(i) or (ii)).

            Until the Distribution Date (or earlier redemption or expiration of
the Rights), new Common Stock certificates issued after July 28, 1997 will
contain a legend incorporating the Rights Agreement by reference. Until the
Distribution Date (or earlier redemption or expiration of the Rights), the
surrender for transfer of any of the Company's Common Stock certificates
outstanding as of July 28, 1997 with or without a copy of the Summary of Rights
attached, will also constitute the transfer of the Rights



                                  4
<PAGE>
associated with the Common Stock represented by such certificate. As soon as
practicable following the Distribution Date, separate certificates evidencing
the Rights ("Right Certificates") will be mailed to holders of record of the
Company's Common Stock as of the close of business on the Distribution Date and
such separate certificates alone will evidence the Rights from and after the
Distribution Date.

            The Rights are not exercisable until the Distribution Date. The
Rights will expire at the close of business on July 15, 2007, unless earlier
redeemed by the Company as described below.

            The Preferred Stock is non-redeemable and, unless otherwise provided
in connection with the creation of a subsequent series of preferred stock,
subordinate to any other series of the Company's preferred stock. The Preferred
Stock may not be issued except upon exercise of Rights. Each share of Preferred
Stock will be entitled to receive when, as and if declared, a quarterly dividend
in an amount equal to 100 times the cash dividends declared on the Company's
Common Stock. In addition, the Preferred Stock is entitled to 100 times any
non-cash dividends (other than dividends payable in equity securities) declared
on the Common Stock, in like kind. In the event of liquidation,



                                  5
<PAGE>
the holders of Preferred Stock will be entitled to receive for each share, a
liquidation payment in an amount equal to the greater of $20,000.00 or 100 times
the payment made per share of Common Stock. Each share of Preferred Stock will
have 100 votes, voting together with the Common Stock. In the event of any
merger, consolidation or other transaction in which Common Stock is exchanged,
each share of Preferred Stock will be entitled to receive 100 times the amount
received per share of Common Stock. The rights of Preferred Stock as to
dividends, liquidation and voting are protected by anti-dilution provisions.

            The number of shares of Preferred Stock issuable upon exercise of
the Rights is subject to certain adjustments from time to time in the event of a
stock dividend on, or a subdivision or combination of, the Common Stock. The
Exercise Price for the Rights is subject to adjustment in the event of
extraordinary distributions of cash or other property to holders of Common
Stock.

            Unless the Rights are earlier redeemed or the transaction is
approved by the Board of Directors, in the event that, after the time that a
Person becomes an Acquiring Person, the Company were to be acquired in a merger
or other business combination (in which any shares of the Company's Common Stock
are changed into or exchanged for



                                  6
<PAGE>
other securities or assets) or more than 50% of the assets or earning power of
the Company and its subsidiaries (taken as a whole) were to be sold or
transferred in one or a series of related transactions, the Rights Agreement
provides that proper provision will be made so that each holder of record of a
Right will from and after such date have the right to receive, upon payment of
the Exercise Price, that number of shares of common stock of the acquiring
company having a market value at the time of such transaction equal to two times
the Exercise Price. In addition, unless the Rights are earlier redeemed, if a
person or group (with certain exceptions) becomes the beneficial owner of 15% or
more of the Company's voting stock, the Rights Agreement provides that proper
provision will be made so that each holder of record of a Right, other than the
Acquiring Person (whose Rights will thereupon become null and void), will
thereafter have the right to receive, upon payment of the Exercise Price, that
number of shares of the Company's Preferred Stock having a market value at the
time of the transaction equal to two times the Exercise Price (such market value
to be determined with reference to the market value of the Company's Common
Stock as provided in the Rights Agreement). The Rights Agreement also grants the
Board of Directors the option, after any



                                  7
<PAGE>
person or group acquires beneficial ownership of 15% or more of the voting stock
but before there has been a 50% acquisition, to exchange one share of common
stock for each then valid right (which would exclude rights held by the
Acquiring Person that have become void).

            Fractions of shares of Preferred Stock (other than fractions that
are integral multiples of one one-hundredth (1/100) of a share) may, at the
election of the Company, be evidenced by depositary receipts. The Company may
also issue cash in lieu of fractional shares which are not integral multiples of
one one-hundredth (1/100) of a share.

            At any time on or prior to the close of business on the tenth day
after the time that a person has become an Acquiring Person (or such later date
as a majority of the Board of Directors may determine), the Company may redeem
the Rights in whole, but not in part, at a price of $.01 per Right ("Redemption
Price"). Immediately upon the effective time of the action of the Board of
Directors of the Company authorizing redemption of the Rights, the right to
exercise the Rights will terminate and the only right of the holders of the
Rights will be to receive the Redemption Price.

            For as long as the Rights are then redeemable, the Company may,
except with respect to the redemption price or date of expiration of the Rights,
amend the Rights in any



                                  8
<PAGE>
manner, including an amendment to extend the time period in which the Rights may
be redeemed. At any time when the Rights are not then redeemable, the Company
may amend the Rights in any manner that does not materially adversely affect the
interests of holders of the Rights as such.

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

            As of July 15, 1997, there were 91,621,896 shares of Common Stock
issued and outstanding (and 15,274,892 shares reserved for issuance under stock
option plans and convertible debt securities). 1,100,000 shares of Preferred
Stock have been reserved for issuance upon exercise of the Rights.

            The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group who attempts to acquire the Company on
terms not approved by the Company's Board of Directors. The Rights should not
interfere with any merger or other business combination approved by the Board
since they may be redeemed by the Company at $.01 per Right at any time until
the close of business on the tenth day (or such later date as



                                  9
<PAGE>
described above) after a person or group has obtained beneficial ownership of
15% or more of the voting stock.

Transfer & Trust Company as rights agent, specifying the terms of the Rights,

Junior Preferred Stock, as Exhibit B the form of Right Certificate and as

                                RIGHTS AGREEMENT

            Agreement, dated as of June 16, 1997, by and between St. Jude
Medical, Inc., a Minnesota corporation (the "Company"), and American Stock
Transfer & Trust Company, a New York corporation (the "Rights Agent").


                             W I T N E S S E T H :


            WHEREAS, on July 16, the Board of Directors of the
Company authorized the issuance of, and declared a dividend payable in, one
right (a "Right") for each share of Common Stock, $0.10 par value per share, of
the Company outstanding as of the close of business on July 28, 1997 (the
"Record Date"), each such Right representing the right to purchase one
one-hundredth of a share of Series B Junior Preferred Stock of the Company
("Preferred Stock") having the rights and preferences set forth in the form of
Certificate of Designations, Preferences and Rights attached hereto as Exhibit C
authorized by the Board of Directors on July 16, 1997, upon the terms and
subject to the conditions hereinafter set forth; and

            WHEREAS, the Board of Directors of the Company further authorized
the issuance of one Right (subject to adjustment) with respect to each share of
Common Stock which may be issued between the Record Date and the earlier to
occur of the Distribution



                                  1
<PAGE>
Date, the Expiration Date or the Final Expiration Date (as such terms are 
hereinafter defined);

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

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

                  (a) "Acquiring Person" shall mean any Person (as such term is
            hereinafter defined) who or which, together with all Affiliates (as
            such term is hereinafter defined) and Associates (as such term is
            hereinafter defined) of such Person, shall be the Beneficial Owner
            (as such term is hereinafter defined) of 15% or more of the Voting
            Stock of the Company then outstanding; provided, that, an Acquiring
            Person shall not include (i) an Exempt Person (as such term is
            hereinafter defined) or (ii) any Person, together with all
            Affiliates and Associates of such Person, who or which would be an
            Acquiring Person solely by reason of (A) being the Beneficial Owner
            of shares of Voting Stock of the Company, the Beneficial Ownership
            of which was acquired by such Person pursuant to any action or
            transaction or series of related actions or transactions approved by
            the Board of Directors before such



                                  2
<PAGE>
            Person otherwise became an Acquiring Person or (B) a reduction in
            the number of issued and outstanding shares of Voting Stock of the
            Company pursuant to a transaction or a series of related
            transactions approved by the Board of Directors of the Company;
            provided, further, that in the event such Person described in this
            clause (ii) does not become an Acquiring Person by reason of
            subclause (A) or (B) of this clause (ii), such Person nonetheless
            shall become an Acquiring Person in the event such Person thereafter
            acquires Beneficial Ownership of an additional 1% of the Voting
            Stock of the Company, unless the acquisition of such additional
            Voting Stock would not result in such Person becoming an Acquiring
            Person by reason of subclause (A) or (B) of this clause (ii).
            Notwithstanding the foregoing, if the Board of Directors of the
            Company determines in good faith that a Person who would otherwise
            be an "Acquiring Person" as defined pursuant to the foregoing
            provisions of this paragraph (a) has become such inadvertently, and
            such Person divests as promptly as practicable (as determined in
            good faith by the Board of Directors) a sufficient number of shares
            of Common Stock so that such Person would no longer be an "Acquiring
            Person" as defined pursuant to the foregoing



                                  3
<PAGE>
            provisions of this paragraph (a), then such Person shall not be
            deemed an "Acquiring Person" for any purposes of this Rights
            Agreement.

                  (b) "Affiliate" shall have the meaning ascribed to such term
            in Rule 12b-2 of the General Rules and Regulations under the
            Securities Exchange Act of 1934, as amended ("Exchange Act"), as in
            effect on the date of this Rights Agreement.

                  (c) "Associate" of a Person (as such term is hereinafter
            defined) shall mean (i) with respect to a corporation, any officer
            or director thereof or of any Subsidiary (as such term is
            hereinafter defined) thereof, or any Beneficial Owner (as such term
            is hereinafter defined) of 10% or more of any class of equity
            security thereof, (ii) with respect to an association, any officer
            or director thereof or of a Subsidiary thereof, (iii) with respect
            to a partnership, any general partner thereof or any limited partner
            thereof who is, directly or indirectly, the Beneficial Owner of a
            10% ownership interest therein, (iv) with respect to a business
            trust, any officer or trustee thereof or of any Subsidiary thereof,
            (v) with respect to any other trust or an estate, any trustee,
            executor or similar fiduciary or any Person who has a 15% or greater
            inter-



                                  4
<PAGE>
            est as a beneficiary in the income from or principal of such trust
            or estate, (vi) with respect to a natural person, any relative or
            spouse of such person, or any relative of such spouse, who has the
            same home as such person, and (vii) any Affiliate of such Person.

                  (d) A person shall be deemed the "Beneficial Owner" of, or to
            "Beneficially Own", any securities (and correlative terms shall have
            correlative meanings):

                        (i) which such Person or any of such Person's Affiliates
                  or Associates beneficially owns, directly or indirectly, for
                  purposes of Section 13(d) of the Exchange Act and Regulations
                  13D and 13G thereunder (or any comparable or successor law or
                  regulation), in each case as in effect on the date hereof; or

                      (ii) which such Person or any of such Person's Affiliates

the Rights Agent to act as agent for the Company and the holders of the Rights
in accordance with the terms and conditions hereof, and the Rights Agent hereby

            Section 3.  Issuance of Right Certificates.

            (a) On the Record Date (or as soon as practicable thereafter), the
Company or the Rights Agent shall send a copy of a Summary of Rights, in
substantially the form attached hereto as Exhibit A (the "Summary of Rights"),
by first class mail, postage prepaid, 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.

Acquiring Person) after the date of the commencement by any Person (other than
an Exempt Person) of, or the first public announcement of the intent of any

upon the successful consummation of which such Person, together with its
Affiliates and Associates, would be the Beneficial Owner of 15% or more of the

any shares are actually purchased pursuant to any such offer) (the earlier of
such dates being herein referred to as the "Distribution Date"), (x) the Rights
shall be evidenced by the certificates for Common Stock registered in the name
of the holders of Common Stock (together with, in the case of certificates for
Common Stock outstanding as of the Record Date, the Summary of Rights) and not
by separate Right certificates and the record holders of such certificates for
Common Stock shall be the record holders of the Rights represented thereby and
(y) each Right shall be transferable only simultaneously and together with the
transfer of a share of Common Stock (subject to adjustment as hereinafter
provided). Until the Distribution Date (or, if earlier, the Expiration Date or
Final Expiration Date), the surrender for transfer of any certificate for Common
Stock shall constitute the surrender for



                                  13
<PAGE>
transfer of the Right or Rights associated with the Common Stock evidenced
thereby, whether or not accompanied by a copy of the Summary of Rights.

            (c) Rights shall be issued in respect of all shares of Common Stock
that become outstanding after the Record Date but prior to the earlier of the
Distribution Date, the Expiration Date or the Final Expiration Date and, in
certain circumstances provided in Section 22 hereof, may be issued in respect of
shares of Common Stock that become outstanding after the Distribution Date.
Certificates for Common Stock (including, without limitation, certificates
issued upon original issuance, disposition from the Company's treasury or
transfer or exchange of Common Stock) after the Record Date but prior to the
earliest of the Distribution Date, the Expiration Date, or the Final Expiration
Date (or, in certain circumstances as provided in Section 22 hereof, after the
Distribution Date) shall have impressed, printed, written or stamped thereon or
otherwise affixed thereto the following legend:

            This certificate also evidences and entitles the holder hereof to
      the same number of Rights (subject to adjustment) as the number of shares
      of Common Stock represented by this certificate, such Rights being on the
      terms provided under the Rights Agreement between St. Jude Medical, Inc.
      and American Stock Transfer & Trust Company (the "Rights Agent"), dated as
      of July 16, 1997, as it may be amended from time to time (the "Rights
      Agreement"), the terms of which are incorporated herein by reference and a
      copy of which is on file at the principal executive offices of St. Jude
      Medical, Inc. Under certain circumstances, as set



                                  14
<PAGE>
      forth in the Rights Agreement, such Rights shall be evidenced by separate
      certificates and shall no longer be evidenced by this certificate. St.
      Jude Medical, Inc. shall mail to the registered holder of this certificate
      a copy of the Rights Agreement without charge within five days after
      receipt of a written request therefor. Under certain circumstances as
      provided in Section 7(e) of the Rights Agreement, Rights issued to or
      Beneficially Owned by Acquiring Persons or their Affiliates or Associates
      (as such terms are defined in the Rights Agreement) or any subsequent
      holder of such Rights shall be null and void and may not be transferred to
      any Person.

            (d) As soon as practicable after the Distribution Date, the Company
will prepare and execute, the Rights Agent will countersign, and the Company
will send or cause to be sent (and the Rights Agent will, if requested, send),
by first class mail, postage prepaid, to each record holder of the Common Stock
as of the close of business on the Distribution Date, as shown by the records of
the Company, at the address of such holder shown on such records, a certificate
in the form provided by Section 4 hereof (a "Right Certificate"), evidencing one
Right (subject to adjustment as provided herein) for each share of Common Stock
so held. As of and after the Distribution Date, the Rights shall be evidenced
solely by Right Certificates and may be transferred by the transfer of the Right
Certificate as permitted hereby, separately and apart from any transfer of one
or more shares of Common Stock.

            Section 4. Form of Right Certificates. The Right Certificates (and
the forms of election to purchase shares, cer-



                                  15
<PAGE>
tificate and assignment to be printed on the reverse thereof), when, as and if
issued, shall be substantially in the form set forth in Exhibit B hereto and may
have such marks of identification or designation and such legends, summaries or
endorsements printed thereon as may be required to comply with any law or with
any rule or regulation made pursuant thereto or with any rule or regulation of
any stock exchange on which the Common Stock or the Rights may from time to time
be listed or as the Company may deem appropriate to conform to usage or
otherwise and as are not inconsistent with the provisions of this Rights
Agreement. Subject to the provisions of Section 22 hereof, Right Certificates
evidencing Rights whenever issued, (i) shall be dated as of the date of issuance
of the Rights they represent and (ii) subject to adjustment from time to time as
provided herein, on their face shall entitle the holders thereof to purchase
such number of shares (including fractional shares which are integral multiples
of one-hundredth of a share) of Preferred Stock as shall be set forth therein at
the price payable upon exercise of a Right provided by Section 7(b) hereof as
the same may from time to time be adjusted as provided herein (the "Exercise
Price").

            Section 5.  Countersignature and Registration.

            (a) Each Right Certificate shall be executed on behalf of the
Company by its Chairman of the Board, President or any Vice President, either
manually or by facsimile signature, which



                                  16
<PAGE>
shall be attested by the Secretary or an Assistant Secretary of the Company,
either manually or by facsimile signature. Each Right Certificate shall be
countersigned by the Rights Agent either manually or by facsimile signature and
shall not be valid for any purpose unless so countersigned. In case any officer
of the Company who shall have signed any Right Certificate shall cease to be
such officer of the Company before countersignature by the Rights Agent and
issuance and delivery of the certificate by the Company, such Right Certificate,
nevertheless, may be countersigned by the Rights Agent and issued and delivered
with the same force and effect as though the person who signed such Right
Certificates had not ceased to be such officer of the Company. Any Right
Certificate may be signed on behalf of the Company by any person who, on the
date of the execution of such Right Certificate, shall be a proper officer of
the Company to sign such Right 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 one or more offices designated as
the appropriate place for surrender of Right Certificates upon exercise or
transfer, and in such other locations as may be required by law, books for
registration and transfer of the Right Certificates issued hereunder. Such books



                                  17
<PAGE>
shall show the names and addresses of the respective holders of the Right
Certificates, the number of Rights evidenced on its face by each of the Right
Certificates and the date of each of the Right Certificates.

            Section 6. Transfer, Split Up, Combination and Exchange of Right
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates.

            (a) Subject to the provisions of Section 7(e), 7(f) and 14 hereof,
at any time after the Close of Business on the Distribution Date, and at or
prior to the Close of Business on the earlier of the Expiration Date or the
Final Expiration Date, any Right Certificate, may be (i) transferred or (ii)
split up, combined or exchanged for one or more other Right Certificates,
entitling the registered holder to purchase a like number of shares of Preferred
Stock as the Right Certificate or Rights Certificates surrendered then entitled
such holder to purchase. Any registered holder desiring to transfer any Right
Certificate shall surrender the Right Certificate at the office of the Rights
Agent designated for the surrender of Right Certificates with the form of
certificate and assignment on the reverse side thereof duly endorsed (or
enclosed with such Right Certificate a written instrument of transfer in form
satisfactory to the Company and the Rights Agent), duly executed by the
registered holder thereof or his attorney duly authorized in writing, and with
such signa-



                                  18
<PAGE>
ture duly guaranteed. Any registered holder desiring to split up, combine or
exchange any Right Certificate shall make such request in writing delivered to
the Rights Agent, and shall surrender the Right Certificate to be split up,
combined or exchanged at the office of the Rights Agent designated therefor.
Thereupon, the Rights Agent shall countersign and deliver to the person entitled
thereto a Right Certificate or Right Certificates, as the case may be, as so
requested. The Company may require payment of a sum sufficient to cover any
Transfer Tax that may be imposed in connection with any transfer, split up,
combination or exchange of any Right Certificates.

            (b) Subject to the provisions of Section 7(e), 7(f) and 14 hereof,
upon receipt by the Company and the Rights Agent of evidence reasonably
satisfactory to them of the loss, theft, destruction or mutilation of a Right
Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to them and, if requested by the Company,
reimbursement to the Company and the Rights Agent of all reasonable expenses
incidental thereto, or upon surrender to the Rights Agent and cancellation of
the Right Certificate if mutilated, the Company shall issue and deliver a new
Right Certificate of like tenor to the Rights Agent for delivery to the
registered owner in lieu of the Right Certificate so lost, stolen, destroyed or
mutilated.

            (a) The Rights shall not be exercisable until, and shall become
exercisable on, the Distribution Date (unless otherwise provided herein,
including, without limitation, the restrictions on exercisability set forth in
Section 7(e) and 23(a) hereof). Except as otherwise provided herein, the Rights
may be exercised, in whole or in part, at any time commencing with the
Distribution Date upon surrender of the Right Certificate, with the form of
election to purchase and certificate on the reverse side thereof duly executed
(with signatures duly guaranteed), to the Rights Agent at the principal office
of the Rights Agent in New York, New York, together with payment of the Exercise
Price for each Right exercised, subject to adjustment as hereinafter provided,

provided in Section 23 hereof (such earlier date being herein referred to as the
"Expiration Date").

            (b) The Exercise Price shall initially be $200.00 for each one
one-hundredth (1/100) of a share of Preferred Stock issued pursuant to the
exercise of a Right. The Exercise Price and the number of shares of Preferred
Stock or other securities to be acquired upon exercise of a Right shall be
subject to



                                  20
<PAGE>
adjustment from time to time as provided in Sections 11 and 13 hereof. The
Exercise Price shall be payable in lawful money of the United States of America,
in accordance with paragraph (c) below.

            (c) Except as otherwise provided herein, upon receipt of a Right
Certificate representing exercisable Rights with the form of election to
purchase duly executed, accompanied by payment by certified check, cashier's
check, bank draft or money order payable to the Company or the Rights Agent of
the Exercise Price for the shares to be purchased and an amount equal to any
applicable Transfer Tax required to be paid by the holder of the Right
Certificate in accordance with Section 9(e) hereof, the Rights Agent shall
thereupon promptly (i) requisition from any transfer agent of the Preferred
Stock of the Company one or more certificates representing the number of shares
of Preferred Stock to be so purchased, and the Company hereby authorizes and
directs such transfer agent to comply with all such requests, (ii) as provided
in Section 14(b), at the election of the Company, cause depositary receipts to
be issued in lieu of fractional shares of Preferred Stock, (iii) if the election
provided for in the immediately preceding clause (ii) has not been made,
requisition from the Company the amount of cash to be paid in lieu of the
issuance of fractional shares in accordance with Section 14(b) hereof, (iv)
after receipt of such Preferred Stock certificates



                                  21
<PAGE>
and, if applicable, depositary receipts, cause the same to be delivered to or
upon the order of the registered holder of such Right Certificate, registered in
such name or names as may be designated by such holder and (v) when appropriate,
after receipt, promptly deliver such cash to or upon the order of the registered
holder of such Right Certificate; provided, however, that in the case of a
purchase of securities, other than Preferred Stock, pursuant to Section 13
hereof, the Rights Agent shall promptly take the appropriate actions
corresponding in such case to that referred to in the foregoing clauses (i)
through (v) of this Section 7(c). Notwithstanding the foregoing provisions of
this Section 7(c), the Company may suspend the issuance of shares of Preferred
Stock upon exercise of a Right for a reasonable period, not in excess of 90
days, during which the Company seeks to register under the Securities Act of
1933, as amended (the "Act"), and any applicable securities law of any other
jurisdiction, the shares of Preferred Stock to be issued pursuant to the Rights;
provided, however, that nothing contained in this Section 7(c) shall relieve the
Company of its obligations under Section 9(c) hereof.

            (d) In case the registered holder of any Right Certificate shall
exercise less than all the Rights evidenced thereby, a new Right Certificate
evidencing Rights equivalent to the Rights remaining unexercised shall be issued
by the Rights



                                  22
<PAGE>
Agent to the registered holder of such Right Certificate or his assign, subject
to the provisions of Section 14(b) hereof.

            (e) Notwithstanding any provision of this Rights Agreement to the
contrary, from and after the time (the "invalidation time") when any Person
first becomes an Acquiring Person, any Rights that are beneficially owned by (x)
such Acquiring Person (or any Associate or Affiliate of such Acquiring Person),
(y) a transferee of such Acquiring Person (or any such Associate or Affiliate)
who becomes a transferee after the invalidation time or (z) a transferee of such
Acquiring Person (or any such Associate or Affiliate) who becomes a transferee
prior to or concurrently with the invalidation time pursuant to either (I) a
transfer from the Acquiring Person to holders of its equity securities or to any
Person with whom it has any continuing agreement, arrangement or understanding
regarding the transferred Rights or (II) a transfer which the Board of Directors
has determined is part of a plan, arrangement or understanding which has the
purpose or effect of avoiding the provisions of this Section 7(e), and
subsequent transferees of such Persons referred to in clause (y) and (z) above,
shall be void without any further action and any holder of such Rights shall
thereafter have no rights whatsoever with respect to such Rights under any
provision of this Rights Agreement. The Company shall use all reasonable efforts
to ensure that the provisions of



                                  23
<PAGE>
this Section 7(e) are complied with, but shall have no liability to any holder
of Right Certificates or any other Person as a result of its failure to make any
determination with respect to an Acquiring Person or its Affiliates, Associates
or transferees hereunder. No Right Certificate shall be issued pursuant to
Section 3 hereof that represents Rights beneficially owned by an Acquiring
Person whose Rights would be void pursuant to the provisions of this Section
7(e) or any Associate or Affiliate thereof; no Right Certificate shall be issued
at any time upon the transfer of any Rights to an Acquiring Person whose Rights
would be void pursuant to the provisions of this Section 7(e) or any Associate
or Affiliate thereof or to any nominee of such Acquiring Person, Associate or
Affiliate; and any Right Certificate delivered to the Rights Agent for transfer
to an Acquiring Person whose Rights would be void pursuant to the provisions of
this Section 7(e) shall be cancelled.

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



                                  24
<PAGE>
additional evidence of the identity of the Beneficial Owner (or former
Beneficial Owner) or Affiliates or Associates thereof as the Company shall
reasonably request.

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

            Section 9. Reservation and Availability of Shares of Preferred
Stock.

            (a) The Company covenants and agrees that it will cause to be
reserved and kept available out of its authorized and unissued shares of
Preferred Stock or out of authorized and



                                  25
<PAGE>
issued shares of Preferred Stock held in its treasury, such number of shares of
Preferred Stock as will from time to time be sufficient to permit the exercise
in full of all outstanding Rights.

            (b) The Company shall use its best efforts to cause, from and after
such time as the Rights become exercisable, all shares of Preferred Stock issued
or reserved for issuance in accordance with this Rights Agreement to be listed,
upon official notice of issuance, upon the principal national securities
exchange, if any, upon which the Common Stock is listed or, if the principal
market for the Common Stock is not on any national securities exchange, to be
eligible for quotation in the National Association of Securities Dealers'
Automated Quotation System or any successor thereto or other comparable
quotation system.

            (c) The Company covenants and agrees that it will take all such
action as may be necessary to insure that all shares of Preferred Stock
delivered upon exercise of Rights shall, at the time of delivery of the
certificates for such shares (subject to payment of the Exercise Price in
respect thereof), be duly and validly authorized and issued and fully paid and
nonassessable shares.

            (d) The Company shall use its best efforts to (i) file, as soon as
practicable following the occurrence of the event described in Section
11(a)(ii), or as soon as is required



                                  26
<PAGE>
by law following the Distribution Date, as the case may be, a registration
statement under the Act, with respect to the shares of Preferred Stock
purchasable upon exercise of the Rights on an appropriate form, (ii) cause such
registration statement to become effective as soon as practicable after such
filing, and (iii) cause such registration statement to remain effective (with a
prospectus at all times meeting the requirements of the Act) until the earlier
of (A) the date as of which the Rights are no longer exercisable for Preferred
Stock, and (b) the date of the expiration of the Rights. The Company may
temporarily suspend, for a period of time not to exceed ninety days, the
issuance of shares of Preferred Stock upon exercise of a Right in order to
prepare and file a registration statement under the Act and permit it to become
effective. The Company will also take such action as may be appropriate under,
or to ensure compliance with, the securities or "blue sky" laws of the various
states in connection with the exercisability of the Rights. Notwithstanding any
provision of this Agreement to the contrary, the Rights shall not be exercisable
in any jurisdiction unless the requisite qualification in such jurisdiction
shall have been obtained and until a registration statement under the Act (if
required) shall have been declared effective.

            (e) The Company covenants and agrees that it will pay when due and
payable any and all federal and state Transfer Taxes



                                  27
<PAGE>
which may be payable in respect of the issuance or delivery of the Right
Certificates or of any shares of Preferred Stock issued or delivered upon the
exercise of Rights. The Company shall not, however, be required to pay any
Transfer Tax which may be payable in respect of any transfer or delivery of a
Right Certificate to a Person other than, or the issuance or delivery of
certificates for Preferred Stock upon exercise of Rights in a name other than
that of, the registered holder of the Right Certificate, and the Company shall
not be required to issue or deliver a Right Certificate or certificate for
Preferred Stock to a Person other than such registered holder until any such
Transfer Tax shall have been paid (any such Transfer Tax being payable by the
holder of such Right Certificate at the time of surrender) or until it has been
established to the Company's satisfaction that no such Transfer Tax is due.

            Section 10. Preferred Stock Record Date. Each Person in whose name
any certificate for shares of Preferred Stock is issued upon the exercise of
Rights shall for all purposes be deemed to have become the holder of record of
the Preferred Stock represented thereby on, and such certificate shall be dated
as of, the date upon which the Right Certificate evidencing such Rights was duly
surrendered and payment of the Exercise Price (and any applicable Transfer
Taxes) was made; provided, however, that, if the date of such surrender and
payment is a date upon



                                  28
<PAGE>
which the Preferred Stock transfer books of the Company are closed, such Person
shall be deemed to have become the record holder of such shares on, and such
certificate shall be dated as of, the next succeeding Business Day on which the
Preferred Stock transfer books of the Company are open. Prior to the exercise of
the Rights evidenced thereby, the holder of a Right Certificate, as such, shall
not be entitled to any rights of a stockholder of the Company with respect to
shares for which the Rights shall be exercisable, including, without limitation,
the right to vote, to receive dividends or other distributions or to exercise
any pre-emptive rights, and shall not be entitled to receive any notice of any
proceedings of the Company, except as provided herein.

            Section 11. Adjustment of Exercise Price or Number of Shares. The
Exercise Price and the number of shares of Preferred Stock which may be
purchased upon exercise of a Right are subject to adjustment from time to time
as provided in this Section 11.

                  (a) (i) In the event the Company shall at any time after the
            date of this Rights Agreement (A) declare or pay any dividend on
            Common Stock payable in shares of Common Stock, (B) subdivide or
            split the outstanding shares of Common Stock into a greater number
            of shares or (C) combine or consolidate the outstanding shares of
            Common Stock into a smaller number of shares or effect a reverse
            split of the



                                  29
<PAGE>
            outstanding shares of Common Stock, then and in each such event the
            number of shares of Preferred Stock issuable upon the exercise of a
            Right after the record date for such event (if one shall have been
            established or, if not, after the date of such event) shall be the
            number of shares of Preferred Stock issuable immediately prior to
            such event multiplied by a fraction the numerator of which is the
            number of Rights outstanding immediately prior to such event and the
            denominator of which is the number of Rights outstanding immediately
            after such event and the Exercise Price after such event shall be
            the Exercise Price in effect immediately prior to such event
            multiplied by such fraction. If an event occurs which would require
            an adjustment under both this Section 11(a)(i) and Section 11(a)(ii)
            hereof, the adjustment provided for in this Section 11(a)(i) shall
            be in addition to, and shall be made prior to, any adjustment
            required pursuant to Section 11(a)(ii).

                  (ii) Subject to Section 27 of this Agreement, in the event
            that any Person (other than an Exempt Person), alone or together
            with its Affiliates and Associates, shall become an Acquiring
            Person, then, subject to the last sentence of Section 23(a) and



                                  30
<PAGE>
            except as otherwise provided in this Section 11, each holder of a
            Right, except as provided in Section 7(e) hereof, shall thereafter
            have the right to receive upon exercise of such Right in accordance
            with the terms of this Rights Agreement and payment of the Exercise
            Price, the greater of (1) the number of one one-hundredths of a
            share of Preferred Stock for which such Right was exercisable
            immediately prior to the first occurrence of the event described in
            this Section 11(a)(ii) or (2) such number of one one-hundredths of a
            share of Preferred Stock, based on the per share Fair Market Value
            of the Preferred Stock (determined pursuant to Section 11(b) hereof)
            on the date of such first occurrence, having a value equal to twice
            the Exercise Price; provided, however, that if the transaction that
            would otherwise give rise to the foregoing adjustment is also
            subject to the provisions of Section 13 hereof, then only the
            provisions of Section 13 hereof shall apply and no adjustment shall
            be made pursuant to this Section 11(a)(ii).

                  (iii) In the event that the Company does not have available
            sufficient authorized but unissued Preferred Stock to permit the
            adjustments required pursuant to the foregoing subparagraph (i) or
            the exercise in full



                                  31
<PAGE>
            of the Rights in accordance with the foregoing subpara- graph (ii),
            the Company shall take all such action as may be necessary to
            authorize and reserve for issuance such number of additional shares
            of Preferred Stock as may from time to time be required to be issued
            upon the exercise in full of all Rights from time to time
            outstanding and, if necessary, shall use its best efforts to obtain
            stockholder approval thereof. In lieu of issuing shares of Preferred
            Stock in accordance with the foregoing subparagraphs (i) and (ii),
            the Company may, if the Board of Directors determines that such
            action is necessary or appropriate and not contrary to the interests
            of holders of Rights, elect to issue or pay, upon the exercise of
            the Rights, cash, property, shares of Preferred or Common Stock, or
            any combination thereof, having an aggregate Fair Market Value equal
            to the Fair Market Value of the shares of Preferred Stock which
            otherwise would have been issuable pursuant to Section 11(a)(ii),
            which Fair Market Value shall be determined by an investment banking
            firm selected by the Board of Directors. For purposes of the
            preceding sentence, the Fair Market Value of the Preferred Stock
            shall be as determined pursuant to Section 11(b). Subject to Section
            23 hereof, any such election by the



                                  32
<PAGE>
            Board of Directors of the Company must be made and publicly
            announced within thirty (30) days after the date on which the event
            described in Section 11(a)(ii) occurs. 

            (b) For the purpose of this Rights Agreement, the "Fair Market
Value" of any share of Preferred Stock, Common Stock or any other stock or any
Right or other security or any other property on any date shall be determined as
provided in this Section 11(b). In the case of a publicly-traded stock or other
security, the Fair Market Value on any date shall be deemed to be the average of
the daily closing prices per share of such stock or per unit of such other
security for the 30 consecutive Trading Days (as such term is hereinafter
defined) immediately prior to such date; provided, however, that in the event
that the Fair Market Value per share of any share of Common Stock is determined
during a period which includes any date that is within 30 Trading Days after (i)
the ex-dividend date for a dividend or distribution on such stock payable in
shares of Common Stock or securities convertible into shares of Common Stock, or
(ii) the effective date of any subdivision, split, combination, consolidation,
reverse stock split or reclassification of such stock, then, and in each such
case, the Fair Market Value shall be appropriately adjusted by the Board of
Directors of the Company to take into account ex-dividend or post-effective date
trading. The closing



                                  33
<PAGE>
price for any day shall be the last sale price, regular way, or, in case no such
sale takes place on such day, the average of the closing bid and asked prices,
regular way (in either case, as reported in the applicable transaction reporting
system with respect to securities listed or admitted to trading on the New York
Stock Exchange), or, if the securities are not listed or admitted to trading on
the New York Stock Exchange, as reported in the applicable transaction reporting
system with respect to securities listed on the principal national securities
exchange on which such security is listed or admitted to trading; or, if not
listed or admitted to trading on any national securities exchange, the last
quoted price (or, if not so quoted, the average of the high bid and low asked
prices) in the over-the-counter market, as reported by the National Association
of Securities Dealers, Inc. Automated Quotation System ("NASDAQ") or such other
system then in use; or, if no bids for such security are 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 such security selected by the Board
of Directors of the Company. The term "Trading Day" shall mean a day on which
the principal national securities exchange on which such security is listed or
admitted to trading is open for the transaction of business or, if such security
is not listed or admitted to trading on any national securities exchange, a



                                  34
<PAGE>
Business Day. If a security is not publicly held or not so listed or traded,
"Fair Market Value" shall mean the fair value per share of stock or per other
unit of such other security, as determined by an independent investment banking
firm experienced in the valuation of securities selected in good faith by the
Board of Directors of the Company, or, if no such investment banking firm is, in
the good faith judgment of the Board of Directors, available to make such
determination, in good faith by the Board of Directors of the Company; provided,
however, that for purposes of making the adjustment provided for by Section
11(a)(ii) hereof, the Fair Market Value of a share of Preferred Stock shall not
be less than 100% of the product of the Fair Market Value of a share of Common
Stock multiplied by the higher of the then Dividend Multiple or Vote Multiple
applicable to the Preferred Stock (as defined in the Certificate of Designations
relating to the Preferred Stock) and shall not exceed 105% of the product of the
then Fair Market Value of a share of Common Stock multiplied by the higher of
the then Dividend Multiple or Vote Multiple applicable to the Preferred Stock.
In the case of property other than securities, the "Fair Market Value" thereof
shall be determined in good faith by the Board of Directors of the Company based
upon such appraisals or valuation reports of such independent experts as the
Board of Directors of the Company shall in good faith determine to be
appropriate in accordance



                                  35
<PAGE>
with good business practices and the interests of the holders of Rights. Any
such determination of Fair Market Value shall be described in a statement filed
with the Rights Agent and shall be binding upon the Rights Agent.

            (c) All calculations under this Section 11 shall be made to the
nearest cent or to the nearest one one-hundredth of a share, as the case may be.

            (d) Irrespective of any adjustment or change in the Exercise Price
or the number of shares of Preferred Stock issu- able upon the exercise of the
Rights, the Right Certificates theretofore and thereafter issued may continue to
express the Exercise Price and the number of shares to be issued upon exercise
of the Rights as in the initial Right Certificates issued hereunder but,
nevertheless, shall represent the Rights as so adjusted.

            (e) Before taking any action that would cause an adjustment reducing
the purchase price per whole share of Preferred Stock upon exercise of the
Rights below the then par value, if any, of the shares of Preferred Stock, the
Company shall use its best efforts to take any corporate action which may, in
the opinion of its counsel, be necessary in order that the Company may validly
and legally issue fully paid and non-assessable shares of such Preferred Stock
at such adjusted purchase price per share.



                                  36
<PAGE>
            (f) Anything in this Section 11 to the contrary notwithstanding, in
the event of any reclassification of stock of the Company or any
recapitalization, reorganization or partial liquidation of the Company or
similar transaction, the Company shall be entitled to make such further
adjustments in the number of shares of Preferred Stock which may be acquired
upon exercise of the Rights, and such adjustments in the Exercise Price
therefor, in addition to those adjustments expressly required by the other
paragraphs of this Section 11, as the Board of Directors of the Company shall
determine to be necessary or appropriate in order for the holders of the Rights
in such event to be treated equitably and in accordance with the purpose and
intent of this Rights Agreement or in order that any such event shall not, but
for such adjustment, in the opinion of counsel to the Company, result in the
stockholders of the Company being subject to any United States federal income
tax liability by reason thereof.

            (g) In the event the Company shall at any time after the Record Date
make any distribution on the shares of Common Stock of the Company, whether by
way of a dividend or a reclassi- fication of stock, a recapitalization,
reorganization or partial liquidation of the Company or otherwise, in cash or
any debt security, debt instrument, real or personal property or any other
property (other than any shares of Common Stock or other capital stock of the
Company and other than any right or warrant to



                                  37
<PAGE>
acquire any such shares, including any debt security convertible into or
exchangeable for any such share, at less than the Fair Market Value of such
shares) and the amount of such cash dividend or the Fair Market Value of such
debt security, debt instrument or property exceeds 150% of the aggregate amount
of the cash dividends declared or paid on the Common Stock of the Company in the
15-month period immediately preceding such distribution, then and in each such
event, unless such distribution is part of or is made in connection with a
transaction to which Section 11(a)(ii) or Section 13 hereof applies, the
Exercise Price shall be reduced by an amount equal to the cash or the Fair
Market Value of such distribution, as the case may be, per share of Common Stock
of the Company. For purposes hereof, the Fair Market Value of any property
distributed to the holders of shares of Common Stock of the Company shall be the
Fair Market Value of such property as determined by an independent investment
banking firm experienced in the valuation of securities or the other property so
distributed, as the case may be, selected in good faith by the Board of
Directors of the Company, or, if no such investment banking firm is in the good
faith judgment of the Board of Directors available to make such determination,
in good faith by the Board of Directors of the Company, whose determination
shall be final and binding on the Company, the Rights Agent and the holders of
Rights.



                                  38
<PAGE>
            Section 12. Certification of Adjusted Exercise Price or Number of
Shares. Whenever an adjustment is made as provided in Section 11, 13 or 23(c),
the Company shall (a) promptly prepare a certificate setting forth such
adjustment, and a brief statement of the facts giving rise to such adjustment,
(b) promptly file with the Rights Agent and with each transfer agent for the
Preferred Stock a copy of such certificate and (c) mail a brief summary thereof
to each holder of a Right Certificate in accordance with Section 25.
Notwithstanding the foregoing sentence, the failure of the Company to make such
certification or give such notice shall not affect the validity of or the force
or effect of the requirement for such adjustment. Any adjustment to be made
pursuant to Section 11, 13 or 23(c) of this Rights Agreement shall be effective
as of the date of the event giving rise to such adjustment. The Rights Agent
shall be fully protected in relying on any such certificate and on any
adjustment therein contained and shall not be deemed to have knowledge of any
adjustment unless and until it shall have received such certificate.

            Section 13.  Consolidation, Merger or Sale or Transfer
of Assets or Earning Power.

             (a) In the event that, at any time after the time that any Person
becomes an Acquiring Person, (x) the Company shall, directly or indirectly,
consolidate with, or merge with



                                  39
<PAGE>
and into, any other Person or Persons (other than an Exempt Person) and the
Company shall not be the surviving or continuing corporation of such
consolidation or merger, or (y) any Person or Persons (other than an Exempt
Person) shall, directly or indirectly, consolidate with, or merge with and into,
the Company, and the Company shall be the continuing or surviving corporation of
such consolidation or merger and, in connection with such consolidation or
merger, all or part of the outstanding shares of Common Stock shall be changed
into or exchanged for stock or other securities of any other Person (other than
an Exempt Person) or of the Company or cash or any other property, or (z) the
Company or one or more of its Subsidiaries shall, directly or indirectly, sell
or otherwise transfer to any other Person or any Affiliate or Associate of such
Person, in one or more transactions, or the Company or one or more of its
Subsidiaries shall sell or otherwise transfer to any Persons in one 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), then, on the first occurrence of any such event, proper provision shall
be made so that (i) each holder of record of a Right, except as provided in
Section 7(e) hereof, shall thereafter have the right to receive, upon the
exercise thereof and payment of the Exercise Price in accordance with the terms
of this Rights Agreement, such



                                  40
<PAGE>
number of shares of validly issued, fully paid, non-assessable and freely
tradeable Common Stock of the Principal Party (as defined herein), not subject
to any liens, encumbrances, rights of first refusal or other adverse claims, as
shall, based on the Fair Market Value of the Common Stock of the Principal Party
on the date of the Consummation of such consolidation, merger, sale or transfer,
equal twice the Exercise Price; (ii) such Principal Party shall thereafter be
liable for, and shall assume, by virtue of such consolidation, merger, sale or
transfer, all the obligations and duties of the Company pursuant to this Rights
Agreement; (iii) the term "Company" for all purposes of this Rights Agreement
shall thereafter be deemed to refer to such Principal Party; (iv) such Principal
Party shall take such steps (including, but not limited to, the reservation of a
sufficient number of shares of its Common Stock in accordance with the
provisions of Section 9 hereof applicable to the reservation of Preferred Stock)
in connection with such consummation as may be necessary to assure that the
provisions hereof shall thereafter be applicable, as nearly as reasonably may
be, in relation to its shares of Common Stock thereafter deliverable upon the
exercise of the Rights; provided, however, that, upon the subsequent occurrence
of any merger, consolidation, sale of all or substantially all of the assets,
recapitalization, reclassification of shares, reorganization or other
extraordinary transaction in



                                  41
<PAGE>
respect of such Principal Party, each holder of a Right shall thereupon be
entitled to receive, upon exercise of a Right and payment of the Exercise Price,
such cash, shares, rights, warrants and other property which such holder would
have been entitled to receive had it, at the time of such transaction, owned the
shares of Common Stock of the Principal Party purchas- able upon the exercise of
a Right, and such Principal Party shall take such steps (including, but not
limited to, reservation of shares of stock) as may be necessary to permit the
subsequent exercise of the Rights in accordance with the terms hereof for such
cash, shares, rights, warrants and other property and (v) the provisions of
Section 11(a)(ii) hereof shall be of no effect following the occurrence of any
event described in clause (x), (y) or (z) above of this Section 13(a).

            (b)  "Principal Party" shall mean

                  (i) in the case of any transaction described in (x) or (y) of
the first sentence of Section 13(a) hereof: (A) the Person that is the issuer of
the securities into which shares of Common Stock of the Company are changed or
otherwise exchanged or converted in such merger or consolidation, or, if there
is more than one such issuer, the issuer of the Common Stock of which has the
greatest market value or (B) if no securities are so issued, (x) the Person that
is the other party to the merger or consolidation and that survives such merger
or



                                  42
<PAGE>
consolidation, or, if there is more than one such Person, the Person the Common
Stock of which has the greatest market value or (y) if the Person that is the
other party to the merger or consolidation does not survive the merger or
consolidation, the Person that does survive the merger or consolidation
(including the Company if it survives); and

                (ii) in the case of any transaction described in (z) of the
first sentence in 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, or, if each Person that is a party to such
transaction or transactions receives the same portion of the assets or earning
power so transferred or if the Person receiving the greatest portion of the
assets or earning power cannot be determined, whichever of such Persons as is
the issuer of Common Stock having the greatest market value of shares
outstanding; provided, however, that in any such case, if the Common Stock of
such Person is not at such time and has not been continuously over the preceding
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, the term "Principal Party" shall refer to such
other Person, or if such Person is a Subsidiary, directly or indirectly, of more
than one Person, the Common Stocks of all of which are and have been so



                                  43
<PAGE>
registered, the term "Principal Party" shall refer to whichever of such Persons
is the issuer of the Common Stock having the greatest market value of shares
outstanding.

            (c) The Company shall not consummate any consolidation, merger or
sale or transfer of assets or earning power referred to in Section 13(a) unless
the Principal Party shall have a sufficient number of authorized shares of its
Common Stock that have not been issued or reserved for issuance to permit
exercise in full of all Rights in accordance with this Section 13 and unless
prior thereto the Company and the Principal Party involved therein shall have
executed and delivered to the Rights Agent an agreement confirming that the
Principal Party shall, upon consummation of such consolidation, merger or sale
or transfer of assets or earning power, assume this Rights Agreement in
accordance with Section 13(a) hereof and that all rights of first refusal or
preemptive rights in respect of the issuance of shares of Common Stock of the
Principal Party upon exercise of outstanding Rights have been waived and that
such transaction shall not result in a default by the Principal Party under this
Rights Agreement, and further providing that, as soon as practicable after the
date of any consolidation, merger or sale or transfer of assets or earning power
referred to in Section 13(a) hereof, the Principal Party will:



                                  44
<PAGE>
                  (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, use its best efforts
            to cause such registration statement to become effective as soon as
            practicable after such filing and use its best efforts to cause such
            registration statement to remain effective (with a prospectus at all
            times meeting the requirements of the Act) until the date of
            expiration of the Rights, and similarly comply with applicable state
            securities laws;

                  (ii) use its best efforts to list (or continue the listing of)
            the Rights and the securities purchas- able upon exercise of the
            Rights on a national securities exchange or to meet the eligibility
            requirements for quotation on NASDAQ; and

                  (iii) deliver to holders of the Rights historical financial
            statements for the Principal Party which comply in all respects with
            the requirements for registration on Form 10 (or any successor form)
            under the Exchange Act. In the event that any of the transactions
            described in Section 13(a) hereof shall occur at any time after the
            occurrence of a transaction described in Section 11(a)(ii) hereof,
            the Rights which



                                  45
<PAGE>
            have not theretofore been exercised shall, subject to
            the provisions of Section 7(e) hereof, thereafter be
            exercisable in the manner described in Section 13(a).

            (d)  In case the Principal Party which is to be a party
to a transaction referred to in this Section 13 has a provision in any of its
authorized securities or in its Certificate of Incorporation or By-laws or other
instrument governing its corporate affairs, which provision would have the
effect of (i) causing such Principal Party to issue, in connection with, or as a
consequence of, the consummation of a transaction referred to in this Section
13, shares of Common Stock of such Principal Party at less than the then Fair
Market Value per share (determined pursuant to Section 11(b) hereof) or
securities exercisable for, or convertible into, Common Stock of such Principal
Party at less than such then Fair Market Value (other than to holders of Rights
pursuant to this Section 13) or (ii) providing for any special tax or similar
payment in connection with the issuance to any holder of a Right of Common Stock
of such Principal Party pursuant to the provisions of this Section 13, then, in
such event, the Company shall not consummate any such transaction unless prior
thereto the Company and such Principal Party shall have executed and delivered
to the Rights Agent a supplemental agreement providing that the provision in
question of such Principal Party shall have been canceled, waived or amended, or



                                  46
<PAGE>
that the authorized securities shall be redeemed, so that the applicable
provision will have no effect in connection with, or as a consequence of, the
consummation of the proposed transaction.

            Section 14.  Fractional Rights and Fractional Shares.

            (a)  The Company shall not be required to issue
fractions of Rights or to distribute Right Certificates which evidence
fractional Rights (i.e., Rights to acquire less than one one-hundredth of a
share of Preferred Stock), unless such fractional Rights result from a
transaction referred to in Section 11(a)(i) hereof. If the Company shall
determine not to issue such fractional Rights, then, in lieu of such fractional
Rights, there shall be paid to the holders of record of the Right Certificates
with regard to which such fractional Rights would otherwise be issuable, an
amount in cash equal to the same fraction of the Fair Market Value of a whole
Right.

            (b) The Company shall not be required to issue fractions of shares
of Preferred Stock (other than fractions which are integral multiples of
one-hundredth of a share) upon exercise of the Rights or to distribute
certificates which evidence fractional shares (other than fractions which are
integral multiples of one-hundredth of a share). In lieu of issuing fractions of
shares of Preferred Stock, the Company may, at its election, issue depositary
receipts evidencing fractions



                                  47
<PAGE>
of shares pursuant to an appropriate agreement between the Company and a
depositary selected by it, provided that such agreement shall provide that the
holders of such depositary receipts shall have all of the rights, privileges and
preferences to which they would be entitled as owners of the Preferred Stock.
With respect to fractional shares that are not integral multiples of
one-hundredth of a share, if the Company does not issue such fractional shares
or depositary receipts in lieu thereof, there shall be paid to the holders of
record of Right Certificates at the time such Right Certificates are exercised
as herein provided an amount in cash equal to the same fraction of the Fair
Market Value of a share of Preferred Stock.

            (c) The holder of a Right by the acceptance of a Right expressly
waives his right to receive any fractional Right or any fractional shares of
Preferred Stock (other than fractions which are integral multiples of one
one-hundredth of a share) upon exercise of a Right.

            Section 15. Rights of Action. All rights of action in respect of
this Rights Agreement, except the rights of action given to the Rights Agent in
Section 18 hereof, are vested in the respective registered holders of the Right
Certificates (and, prior to the Distribution Date, the holders of record of the
Common Stock); and any holder of record of any Right Certificate (or, prior to
the Distribution Date, of the Common Stock),



                                  48
<PAGE>
without the consent of the Rights Agent or of the holder of any other Right
Certificate (or, prior to the Distribution Date, of the Common Stock), may, in
his own behalf and for his own benefit, enforce, and may institute and maintain
any suit, action or proceeding against the Company to enforce, or otherwise act
in respect of, his right to exercise the Rights evidenced by such Right
Certificate in the manner provided in such Right Certificate and in this Rights
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 Rights Agreement
and will be entitled to specific performance of the obligations under, and
injunctive relief against actual or threatened violations of, the obligations of
any Person subject to this Rights Agreement.

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

            (a) prior to the Distribution Date, the Rights shall be evidenced by
      the certificates for Common Stock registered in the name of the holders of
      Common Stock (together, as applicable, with the Summary of Rights), which
      certificates for Common Stock shall also constitute certificates for



                                  49
<PAGE>
      Rights, and not by separate Right Certificates, and each Right shall be
      transferable only simultaneously and together with the transfer of shares
      of Common Stock;

            (b) after the Distribution Date, the Right Certificates are
      transferable only on the registry books of the Rights Agent if surrendered
      at the office of the Rights Agent designated for such purpose, duly
      endorsed or accompanied by a proper instrument of transfer; and

            (c) the Company and the Rights Agent may deem and treat the person
      in whose name the Right Certificate (or, prior to the Distribution Date,
      the associated Common Stock certificate) is registered as the absolute
      owner thereof and of the Rights evidenced thereby (notwithstanding any
      notations of ownership or writing on the Right 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 shall be affected by any notice to the contrary.

            Section 17. Right Certificate Holder Not Deemed a Stockholder. No
holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of Preferred Stock or any
other securities which may at any time be issuable on the exercise of the Rights
represented thereby, nor shall anything contained herein or in any



                                  50
<PAGE>
Right Certificate be construed to confer upon the holder of any Right
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 (except as provided in Section 7(f) hereof),
or to give or withhold consent to any corporate action (except as provided in
Section 7(f) hereof), or to receive notice of meetings or other actions
affecting stockholders (except as provided in Section 24 hereof), or to receive
dividends or subscription rights, or otherwise, until the Right or Rights
evidenced by such Right Certificate shall have been exercised in accordance with
the provisions hereof.

            Section 18.  Concerning the Rights Agent.

            (a)  The Company agrees to pay to the Rights Agent
reasonable compensation for all services rendered by it hereunder and, from time
to time, on demand of the Rights Agent, its reasonable expenses and counsel fees
and other disbursements incurred in the administration and execution of this
Rights Agreement and the exercise and performance of its duties hereunder. The
Company also agrees to indemnify the Rights Agent for, and to hold it harmless
against, any loss, liability, or expense, incurred without 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



                                  51
<PAGE>
acceptance and administration of this Rights Agreement, including the cost and
expenses of defending against any claim of liability relating to the Rights or
this Rights Agreement.

            (b) The Rights Agent shall be protected against, and shall incur no
liability for or in respect of, any action taken, suffered or omitted by it in
connection with its administration of this Rights Agreement in reliance upon any
Right Certificate or certificate for Preferred 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 of, or Change in Name of, the
Rights Agent.

            (a) Any corporation into which the Rights Agent or any successor
Rights Agent may be merged or with which it may be consolidated, or any
corporation resulting from any merger or consolidation to which the Rights Agent
or any successor Rights Agent shall be a party, or any corporation succeeding to
the corporate trust or stock transfer business of the Rights Agent or any
successor Rights Agent, shall be the successor to the Rights Agent under this
Rights Agreement without the execution or filing of any paper or any further act
on the part of any of the parties



                                  52
<PAGE>
hereto, provided that such corporation would be eligible for appointment as a
successor Rights Agent under the provisions of Section 21 hereof. In case at the
time such successor Rights Agent shall succeed to the agency created by this
Rights Agreement any of the Rights Certificates shall have been countersigned
but not delivered, any such successor Rights Agent may adopt the
countersignature of the predecessor Rights Agent and deliver such Right
Certificates so countersigned; and in case at that time any of the Right
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Right Certificates either in the name of the predecessor Rights
Agent or in the name of the successor Rights Agent; and in all such cases such
Right Certificates shall have the full force provided in the Right Certificates
and in this Rights Agreement.

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



                                  53
<PAGE>
            Section 20. Duties of Rights Agent. The Rights Agent undertakes the
duties and obligations imposed by this Rights Agreement upon the following terms
and conditions, by all of which the Company and the holders of Right
Certificates by their acceptance thereof shall be bound:

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

            (b) Whenever in the performance of its duties under this Rights
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter be proved or established by the Company prior to taking or suffering any
action hereunder, such fact or matter (unless other evidence in respect thereof
be herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by the Chairman of the Board, the President
or any Vice President and by the Treasurer or the Secretary of the Company and
delivered to the Rights Agent. Any such certificate shall be full authorization
to the Rights Agent for any action taken or suffered in good faith by it under
the provisions of this Rights Agreement in reliance upon such certificate.



                                  54
<PAGE>
            (c) The Rights Agent shall be liable hereunder only for its own
negligence, bad faith or willful misconduct.

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

            (e) The Rights Agent shall not be under any responsibility in
respect of the validity of this Rights Agreement or the execution and delivery
hereof (except the due execution hereof by the Rights Agent) or in respect of
the validity or execution of any Right Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any
covenant or condition contained in this Rights Agreement or in any Right
Certificate; nor shall it be responsible for any adjustment required under the
provisions of Section 11 or 13 hereof or responsible for the manner, method or
amount of any such adjustment or the ascertaining of the existence of facts that
would require any such adjustment (except with respect to the exercise of Rights
evidenced by Right Certificates after receipt of a certificate describing any
such adjustment); nor shall it by any act hereunder be deemed to make any
representation or warranty as to the authorization or reservation of any



                                  55
<PAGE>
shares of Preferred Stock to be issued pursuant to this Rights Agreement or any
Right Certificate or as to whether any shares of Preferred Stock will, when
issued, be validly authorized and issued, fully paid and 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 the Rights Agreement.

            (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from the
Chairman of the Board, the President or any Vice President or the Secretary or
the Treasurer of the Company, and to apply to such officers for advice or
instructions in connection with its duties, and it shall 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 shareholder, 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, or contract with or lend money to the
Company or otherwise act as fully and freely as though it were not the



                                  56
<PAGE>
Rights Agent under this Rights Agreement. Nothing herein shall preclude the
Rights Agent from acting in any other capacity for the Company or for any other
legal entity.

            (i) The Rights Agent may execute and exercise any of the rights or
powers hereby vested in it or perform any duty hereunder either itself or by or
through its attorneys or agents, and the Rights Agent shall not be answerable or
accountable for any act, default, 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 reasonable care was exercised in the selection
and continued employment thereof.

            Section 21. Change of Rights Agent. The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Rights Agreement upon 30 days' notice in writing mailed to the Company and to
each transfer agent of the Common Stock and the Preferred Stock by registered or
certified mail. The Company may remove the Rights Agent or any successor Rights
Agent (with or without cause) 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 and the Preferred Stock by registered or certified
mail. If the Rights Agent shall resign or be removed or shall otherwise become
incapable of acting, the Company shall appoint a successor to the Rights Agent.
Notwithstanding the foregoing provisions of this



                                  57
<PAGE>
Section 21, in no event shall the resignation or removal of a Rights Agent be
effective until a successor Rights Agent shall have been appointed and have
accepted such appointment. If the Company shall fail to make such appointment
within a period of 30 days after such removal or after it has been notified in
writing of such resignation or incapacity by the resigning or incapacitated
Rights Agent or by the holder of a Right Certificate (who shall, with such
notice, submit his Right Certificate for inspection by the Company), then the
incumbent Rights Agent or the holder of record of any Right Certificate may
apply to any court of competent jurisdiction for the appointment of a new Rights
Agent. Any successor Rights Agent, whether appointed by the Company or by such a
court, shall be (a) a corporation organized and doing business under the laws of
the United States or of any state thereof, in good standing, which is authorized
under such laws to exercise corporate trust or stock transfer powers and is
subject to supervision or examination in the conduct of its corporate trust or
stock transfer business by federal or state authorities and which has at the
time of its appointment as Rights Agent a combined capital and surplus of at
least $5,000,000 or (b) an Affiliate controlled by a corporation described in
clause (a) of this sentence. After appointment, the successor Rights Agent shall
be vested with the same powers, rights, duties and responsibilities as if it had
been originally



                                  58

<PAGE>
named as Rights Agent without further act or deed, but the predecessor Rights
Agent shall deliver and transfer to the successor Rights Agent any property at
the time held by it hereunder, and execute and deliver any further assurance,
conveyance, act or deed necessary for the purpose. Not later than the effective
date of any such appointment, the Company shall file notice thereof in writing
with the predecessor Rights Agent and each transfer agent of the Common Stock
and Preferred Stock, and mail a notice thereof in writing to the registered
holders of the Right Certificates. Failure to give any notice provided for in
this Section 21, however, or any defect therein, shall not affect the legality
or validity of the resignation or removal of the Rights Agent or the appointment
of the successor Rights Agent, as the case may be. Notwithstanding the foregoing
provisions, in the event of resignation, removal or incapacity of the Rights
Agent, the Company shall have the authority to act as the Rights Agent until a
successor Rights Agent shall have assumed the duties of the Rights Agent
hereunder.

            Section 22. Issuance of New Right Certificates. Notwithstanding any
of the provisions of this Rights Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Right Certificates evidencing Rights in
such form as may be approved by its Board of Directors to reflect any adjustment
or change in the Exercise Price per share and the number or



                                  59
<PAGE>
kind or class of shares of stock or other securities or property purchasable
under the Right Certificates made in accordance with the provisions of this
Rights Agreement.

            Section 23.  Redemption.

            (a) The Company may, at its option, but only by the vote of a
majority of the Board of Directors, redeem all but not less than all of the then
outstanding Rights, at any time prior to the Close of Business on the earlier of
(i) the tenth day following the Stock Acquisition Date (subject to extension by
the Company as provided in Section 26 hereof) or (ii) the Final Expiration Date,
at a redemption price of $.01 per Right, subject to adjustments as provided in
subsection (c) below (the "Redemption Price"). Notwithstanding anything
contained in this Agreement to the contrary, the Rights shall not be exercisable
pursuant to Section 11(a)(ii) prior to the expiration of the Company's right of
redemption hereunder.

            (b) Without any further action and without any notice, the right to
exercise the Rights will terminate effective at the time so designated by action
of the Board of Directors ordering the redemption of the Rights and the only
right thereafter of the holders of Rights shall be to receive the Redemption
Price. Within 10 days after the effective time of the action of the Board of
Directors ordering the redemption of the Rights, the Company shall give notice
of such redemption to the holders of



                                  60
<PAGE>
the then outstanding Rights by mailing such notice to all such holders at their
last addresses as they appear upon the registry books of the Rights Agent or,
prior to the Distribution Date, on the registry books of the transfer agent for
the Common Stock. Any notice which is mailed in the manner herein provided shall
be deemed given, whether or not the holder receives the notice. Each notice of
redemption will state the method by which the payment of the Redemption Price
will be made. At the option of the Board of Directors, the Redemption Price may
be paid in cash to each Rights holder or by the issuance of shares (and, at the
Company's election pursuant to Section 14(b) hereof, cash or depositary receipts
in lieu of fractions of shares other than fractions which are integral multiples
of one one-hundredth (1/100) of a share) of Preferred Stock or Common Stock
having a Fair Market Value equal to such cash payment.

            (c) In the event the Company shall at any time after the date of
this Rights Agreement (A) pay any dividend on Common Stock in shares of Common
Stock, (B) subdivide or split the outstanding shares of Common Stock into a
greater number of shares or (C) combine or consolidate the outstanding shares of
Common Stock into a smaller number of shares or effect a reverse split of the
outstanding shares of Common Stock, then, and in each such event, the Redemption
Price shall be appropriately adjusted by the Board of Directors to reflect the
foregoing.

<PAGE>
            Section 24.  Notice of Proposed Actions.

            (a)  In case the Company, after the Distribution Date,
shall propose (i) to effect any of the transactions referred to in Section
11(a)(i) or 11(g) or (ii) to offer to the holders of record of its Common Stock
options, warrants, or other rights to subscribe for or to purchase shares of
Common Stock (including any security convertible into or exchangeable for Common
Stock) or shares of stock of any class or any other securities, options,
warrants, convertible or exchangeable securities or other rights, or (iii) to
effect any reclassification of its Preferred Stock or Common Stock or any
recapitalization or reorganization of the Company, or (iv) to effect any
consolidation or merger with or into, or to effect any sale or other transfer
(or to permit one or more of its Subsidiaries to effect any sale or other
transfer), in one or more transactions, of 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, or (v) to effect the liquidation, dissolution or
winding up of the Company, then, in each such case, the Company shall give to
each holder of record of a Right Certificate, in accordance with Section 25,

purposes of such transaction referred to in Section 11(a)(i) or such dividend or
distribution, or the date on which such reclas- sification, recapitalization,

merger, sale or transfer of assets, liquidation, dissolution, or winding up is
to take place and the record date for determining participation therein by the
holders of record of Common Stock or Preferred Stock, if any such date is to be
fixed, and such notice shall be so given in the case of any action covered by
clause (i) or (ii) above at least 10 days prior to the record date for
determining holders of record of the Preferred Stock for purposes of such
action, and in the case of any such other action, at least 10 days prior to the
date of the taking of such proposed action or the date of participation therein
by the holders of record of Common Stock or Preferred Stock, whichever shall be
the earlier. The failure to give notice required by this Section 24 or any
defect therein shall not affect the legality or validity of the action taken by
the Company or the vote upon any such action.

            (b) In case any of the transactions referred to in Section 11(a)(i),
11(g) or 13 of this Rights Agreement are proposed, then, in any such case, the

thereof to each holder of Rights.

            Section 26. Supplements and Amendments. For as long as the Rights
are then redeemable and except as provided in the last sentence of this Section
26, the Company may in its sole and absolute discretion, and the Rights Agent
shall if the Company so directs, supplement or amend any provision of this
Agreement without the approval of any holders of the Rights. At any time when
the Rights are not then redeemable and except as provided in the last sentence
of this Section 26, the Company may, and the Rights Agent shall if the Company
so directs, supplement or amend this Rights Agreement without the approval of
any holders of Right Certificates (i) to cure any ambiguity, (ii) to correct or
supplement any provision contained herein which may be defective or inconsistent
with any other provisions herein or (iii) to change or supplement the provisions
hereunder in any manner which the Company may deem necessary or desirable,
provided that no such supplement or amendment pursuant to this clause (iii)
shall materially adversely affect the interest of the holders of Right
Certificates. Upon the delivery of a certificate from an appropriate officer of
the Company which states that the proposed supplement or amendment is in
compliance with the terms of this Section 26, the Rights Agent shall execute
such supplement or amendment. This Agreement may be amended or supplemented at
any



                                  65
<PAGE>
time with the approval of a majority of the registered holders of the Right
Certificates (and, prior to the Distribution Date, the Common Stock).
Notwithstanding anything contained in this Rights Agreement to the contrary, no
supplement or amendment shall be made which changes the Redemption Price or the
Final Expiration Date.

            Section 27. Exchange. (a) The Board of Directors of the Company may,
at its option, at any time after any Person becomes an Acquiring Person,
exchange all or part of the then outstanding and exercisable Rights (which shall
not include Rights that have become void pursuant to the provisions of Section
7(e) hereof) for shares of Common Stock at an exchange ratio of one share per
Right, appropriately adjusted to reflect any stock split, stock dividend or
similar transaction occurring after the date hereof (such exchange ratio being
hereinafter referred to as the "Exchange Ratio"). The Company may, at its option
by action of its Broad of Directors, substitute the Preferred Stock for the
Common Stock otherwise exchangeable for Rights on such basis as the Board deems
advisable. Notwithstanding the foregoing, the Board of Directors shall not be
empowered to effect such exchange at any time after any Person (other than an
Exempt Person), together with all Affiliates and Associates of such Person,
becomes the Beneficial Owner of 50% or more of the Voting Stock then
outstanding.



                                  66
<PAGE>
            (b) Immediately upon the action of the Board of Directors of the
Company ordering the exchange of any Rights pursuant to paragraph (a) of this
Section 27 and without any further action and without any notice, the right to
exercise such Rights shall terminate and the only right thereafter of a holder
of such Rights shall be to receive that number of shares of Common Stock equal
to the number of such Rights held by such holder multiplied by the Exchange
Ratio. The Company shall promptly give public notice of any such exchange;
provided, however, that the failure to give, or any defect in, such notice shall
not affect the validity of such exchange. The Company promptly shall mail a
notice of any such exchange to all of the holders of such Rights at their last
addresses as they appear upon the registry books of the Rights Agent. Any notice
which is mailed in the manner herein provided shall be deemed given, whether or
not the holder receives the notice. Each such notice of exchange will state the
method by which the exchange of the shares of Common Stock for Rights will be
effected and, in the event of any partial exchange, the number of Rights which
will be exchanged. Any partial exchange shall be effected pro rata based on the
number of Rights (other than Rights which have become void pursuant to the
provisions of Section 7(e) hereof) held by each holder of Rights.



                                  67
<PAGE>
            (c) In the event that there shall not be sufficient shares of Common
Stock issued but not outstanding or authorized but unissued to permit any
exchange of Rights as contemplated in accordance with this Section 27, the
Company shall take all such action as may be necessary to authorize additional
shares of Common Stock for issuance upon exchange of the Rights.

            (d) The Company shall not be required to issue fractions of shares
of Common Stock or to distribute certificates which evidence fractional shares.
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 of
Common Stock would otherwise be issuable an amount in cash equal to the same
fraction of the current market value of a whole share of Common Stock. For the
purposes of this paragraph (d), the current market value of a whole share of
Common Stock shall be the closing price of a share of Common Stock for the
Trading Day immediately prior to the date of exchange pursuant to this Section
27.

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

            Section 29. Benefits of this Rights Agreement. Nothing in this
Rights Agreement shall be construed to give to



                                  68
<PAGE>
any person or corporation other than the Company, the Rights Agent and the
registered holders of the Right Certificates (and, prior to the Distribution
Date, the holders of Common Stock in their capacity as holders of the Rights)
any legal or equitable right, remedy or claim under this Rights Agreement; but
this Rights Agreement shall be for the sole and exclusive benefit of the
Company, the Rights Agent and the holders of record of the Right Certificates
(and, prior to the Distribution Date, the holders of Common Stock in their
capacity as holders of the Rights).

            Section 30. Minnesota Contract. This Rights Agreement and each Right
Certificate issued hereunder shall be deemed to be a contract made under the
laws of the State of Minnesota and for all purposes shall be governed by and
construed and enforced in accordance with the laws of such state applicable to
contracts to be made and performed entirely within such state.

            Section 31. Counterparts. This Rights Agreement may be executed in
any number of counterparts and each of such counterparts shall for all purposes
be deemed to be an original, and all such counterparts shall together constitute
but one and the same instrument.

            Section 32. Descriptive Headings. Descriptive headings of the
several Sections of this Rights Agreement are



                                  69

inserted for convenience only and shall not control or affect the meaning or
construction of any of the provisions hereof.

            Section 33. Severability. If any term, provision, covenant or
restriction of this Rights 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 Rights
Agreement shall remain in full force and effect and shall in no way be affected,
impaired or invalidated.

Agreement to be duly executed, all as of the day and year first above written.

                 UNDER CERTAIN CIRCUMSTANCES AS PROVIDED IN THE
                 RIGHTS AGREEMENT (AS REFERRED TO BELOW), RIGHTS
          ISSUED TO OR BENEFICIALLY OWNED BY ACQUIRING PERSONS OR THEIR
        AFFILIATES OR ASSOCIATES (AS SUCH TERMS ARE DEFINED IN THE RIGHTS
        AGREEMENT) OR ANY SUBSEQUENT HOLDER OF SUCH RIGHTS SHALL BE NULL
               AND VOID AND MAY NOT BE TRANSFERRED TO ANY PERSON.

                             ST. JUDE MEDICAL, INC.

                          SUMMARY OF RIGHTS TO PURCHASE
                         SERIES B JUNIOR PREFERRED STOCK



            On July 16, 1997, the Board of Directors of St. Jude Medical, Inc.
(the "Company") declared a dividend distribution of one Preferred Stock Purchase
Right for each outstanding share of Common Stock, par value $.10 per share (the
"Common Stock"), of the Company. The distribution is payable as of July 28, 1997
to stockholders of record on that date. Each Right entitles the registered
holder to purchase from the Company one one-hundredth (1/100) of a share of
preferred stock of the Company, designated as Series B Junior Preferred Stock
(the "Preferred Stock") at a price of $200.00 per one one-hundredth (1/100) of a
share ("Exercise Price"). The description and terms of the Rights are set forth
in a Rights Agreement (the "Rights Agreement") between the Company and American
Stock Transfer & Trust Company, as Rights Agent (the "Rights Agent").

            As discussed below, initially the Rights will not be exercisable,
certificates will not be sent to stockholders and the Rights will automatically
trade with the Common Stock.

            The Rights, unless earlier redeemed by the Board of Directors,
become exercisable upon the close of business on the day (the "Distribution
Date") which is the earlier of (i) the tenth day following a public announcement
that a person or group of affiliated or associated persons, with certain
exceptions set forth below, has acquired beneficial ownership of 15% or more of
the outstanding voting stock of the Company (an "Acquiring Person") and (ii) the
tenth business day (or such later date as may be determined by the Board of
Directors prior to such time as any person or group of affiliated or associated
persons becomes an Acquiring Person) after the date of the commencement or



                                  1
<PAGE>
announcement of a person's or group's intention to commence a tender or exchange
offer the consummation of which would result in the ownership of 15% or more of
the Company's outstanding voting stock (even if no shares are actually purchased
pursuant to such offer); prior thereto, the Rights would not be exercisable,
would not be represented by a separate certificate, and would not be
transferable apart from the Company's Common Stock, but will instead be
evidenced, with respect to any of the Common Stock certificates outstanding as
of July 28, 1997, by such Common Stock certificate with a copy of this Summary
of Rights attached thereto. An Acquiring Person does not include (A) the
Company, (B) any subsidiary of the Company, (C) any employee benefit plan or
employee stock plan of the Company or of any subsidiary of the Company, or any
trust or other entity organized, appointed, established or holding Common Stock
for or pursuant to the terms of any such plan or (D) any person or group whose
ownership of 15% or more of the shares of voting stock of the Company then
outstanding results solely from (i) any action or transaction or transactions
approved by the Board of Directors before such person or group became an
Acquiring Person or (ii) a reduction in the number of issued and outstanding
shares of voting stock of the Company pursuant to a transaction or transactions
approved by the Board of Directors (provided that any person or group that does
not become an Acquiring Person by reason of clause (i) or (ii) above shall
become an Acquiring Person upon acquisition of an additional 1% of the Company's
voting stock unless such acquisition of additional voting stock will not result
in such person or group becoming an Acquiring Person by reason of such clause
(i) or (ii)).

            Until the Distribution Date (or earlier redemption or expiration of
the Rights), new Common Stock certificates issued after July 28, 1997 will
contain a legend incorporating the Rights Agreement by reference. Until the
Distribution Date (or earlier redemption or expiration of the Rights), the
surrender for transfer of any of the Common Stock certificates outstanding as of
July 28, 1997, with or without a copy of this Summary of Rights attached
thereto, will also constitute the transfer of the Rights associated with the
Common Stock represented by such certificate. As soon as practicable following
the Distribution Date, separate certificates evidencing the Rights ("Right
Certificates") will be mailed to holders of record of the Common Stock as of the
close of business on the Distribution Date and such separate certificates alone
will evidence the Rights from and after the Distribution Date.

            The Rights are not exercisable until the Distribution Date. The
Rights will expire at the close of business on July



                                  2

<PAGE>
15, 2007, unless earlier redeemed by the Company as described below.

            The Preferred Stock is nonredeemable and, unless otherwise provided
in connection with the creation of a subsequent series of preferred stock,
subordinate to any other series of the Company's preferred stock. The Preferred
Stock may not be issued except upon exercise of Rights. Each share of Preferred
Stock will be entitled to receive when, as and if declared, a quarterly dividend
in an amount equal to 100 times the cash dividends declared on the Company's
Common Stock. In addition, Preferred Stock is entitled to 100 times any non-cash
dividends (other than dividends payable in equity securities) declared on the
Common Stock, in like kind. In the event of the liquidation of the Company, the
holders of Preferred Stock will be entitled to receive, for each 1/100 of a
share of Preferred Stock, a payment in an amount equal to the greater of $200 or
the payment made per share of Common Stock. Each share of Preferred Stock will
have 100 votes, voting together with the Common Stock. In the event of any
merger, consolidation or other transaction in which Common Stock is exchanged,
each share of Preferred Stock will be entitled to receive 100 times the amount
received per share of Common Stock. The rights of Preferred Stock as to
dividends, liquidation and voting are protected by anti-dilution provisions.

            The number of shares of Preferred Stock issuable upon exercise of
the Rights is subject to certain adjustments from time to time in the event of a
stock dividend on, or a subdivision or combination of, the Common Stock. The
Exercise Price for the Rights is subject to adjustment in the event of
extraordinary distributions of cash or other property to holders of Common
Stock.

            Unless the Rights are earlier redeemed, in the event that, after the
time that a Person becomes an Acquiring Person, the Company were to be acquired
in a merger or other business combination (in which any shares of Common Stock
are changed into or exchanged for other securities or assets) or more than 50%
of the assets or earning power of the Company and its subsidiaries (taken as a
whole) were to be sold or transferred in one or a series of related
transactions, the Rights Agreement provides that proper provision will be made
so that each holder of record of a Right will from and after such date have the
right to receive, upon payment of the Exercise Price, that number of shares of
common stock of the acquiring company having a market value at the time of such
transaction equal to two times the Exercise Price.



                                  3
<PAGE>
            In addition, unless the Rights are earlier redeemed, in the event
that a person or group becomes the beneficial owner of 15% or more of the
Company's voting stock, the Rights Agreement provides that proper provisions
will be made so that each holder of record of a Right, other than the Acquiring
Person (whose Rights will thereupon become null and void), will thereafter have
the right to receive, upon payment of the Exercise Price, that number of shares
of the Preferred Stock having a market value at the time of the transaction
equal to two times the Exercise Price (such market value to be determined with
reference to the market value of the Company's Common Stock as provided in the
Rights Agreement).

            At any time after any person or group becomes an Acquiring Person
and prior to the acquisition by such person or group of 50% or more of the
outstanding voting stock, the Board of Directors of the Company may exchange the
Rights (other than Rights owned by such person or group which will have become
void), in whole or in part, at an exchange ratio of one share of Common Stock
per Right (subject to adjustment).

            Fractions of shares of Preferred Stock (other than fractions which
are integral multiples of one one-hundredth of a share) may, at the election of
the Company, be evidenced by depositary receipts. The Company may also issue
cash in lieu of fractional shares which are not integral multiples of one
one-hundredth of a share.

            At any time on or prior to the close of business on the earlier of
(i) the tenth day after the time that a person has become an Acquiring Person
(or such later date as a majority of the Board of Directors may determine) or
(ii) July 15, 2007, the Company may redeem the Rights in whole, but not in part,
at a price of $.01 per Right (the "Redemption Price"). Immediately upon the
effective time of the action of the Board of Directors of the Company
authorizing 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.

            For as long as the Rights are then redeemable, the Company may,
except with respect to the redemption price or date of expiration of the Rights,
amend the Rights in any manner, including an amendment to extend the time period
in which the Rights may be redeemed. At any time when the Rights are not then
redeemable, the Company may amend the Rights in any manner that does not
materially adversely affect the interests of holders of the Rights as such.

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

            A copy of the Rights Agreement has been filed with the Securities
and Exchange Commission as an Exhibit to a Current Report on Form 8-K dated July
16, 1997. A copy of the Rights Agreement is available free of charge from the
Company. This summary description of the Rights does not purport to be complete
and is qualified in its entirety by reference to the Rights Agreement which is
incorporated in this summary description herein by reference.

may from time to time be adjusted in accordance with the Rights Agreement (the
"Exercise Price"), upon presentation and surrender of this Right Certificate
with the Form of Election to Purchase attached hereto duly executed.

            As provided in the Rights Agreement, the Exercise Price and the
number of shares of Preferred Stock which may be purchased upon the exercise of
the Rights evidenced by this Right Certificate are subject to modification and
adjustment upon the happening of certain events and, upon the happening of
certain events, securities other than shares of Preferred Stock, or other
property, may be acquired upon exercise of the Rights evidenced by this Right
Certificate, as provided in the Rights Agreement.

            This Right 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 hereof and to which

shall have entitled such holder to purchase. If this Right Certificate shall be
exercised in part, the holder shall be entitled to receive upon surrender
hereof, another Right Certificate or Right 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 or
under certain other circumstances at a redemption price of $.01 per Right.

            No fractional shares of Preferred Stock (other than fractions which
are integral multiples of one one-hundredth (1/100) of a share) are required to
be issued upon the exercise of any Right or Rights evidenced hereby, and in lieu
thereof the Company may cause depositary receipts to be issued and/or a cash
payment may be made, as provided in the Rights Agreement.

            No holder of this Right Certificate, as such, shall be entitled to

                             ST. JUDE MEDICAL, INC.

                       Pursuant to Section 302.401 of the
                       Minnesota Business Corporation Law


            We, Ronald A. Matricaria, President and Chief Executive Officer and
Kevin O'Malley, Secretary, of St. Jude Medical, Inc., a corporation organized
and existing under the Minnesota Business Corporation Act (the "Company"), in
accordance with the provisions of Section 302A.401 of such law, DO HEREBY
CERTIFY:

            That pursuant to the authority conferred upon the Board of Directors
by the Articles of Incorporation of the Company, the Board of Directors on July
16, 1997 adopted the following resolution which creates a series of 1,100,000
shares of preferred stock designated as Series B Junior Preferred Stock:

            RESOLVED, that pursuant to the authority vested in the Board of
Directors of the Company in accordance with the provisions of its Articles of
Incorporation, a series of preferred stock of the Company be, and hereby is,
created, and the designation and amount thereof and the voting powers,
preferences and relative, participating, optional or other special rights of the
shares of such series, and the qualifications, limitations or restrictions
thereof, be, and hereby are, as follows:






NYFS03...:\18\55218\0001\139\AGR7107R.30B

                                      1

<PAGE>
            Section 1. Designation and Amount. The shares of such series shall
be designated as "Series B Junior Preferred Stock" (the "Series B Preferred
Stock") and the number of shares constituting such series shall be 1,100,000.

            Section 2.  Dividends and Distributions.

            (A)  Subject to the provisions for adjustment here-
inafter set forth, the holders of shares of Series B Preferred Stock shall be
entitled to receive, when, as and if declared by the Board of Directors out of
funds legally available for the purpose, cash dividends in an amount per share
(rounded to the nearest cent) equal to 100 times the aggregate per share amount
of all cash dividends declared or paid on the Common Stock, $0.10 par value per
share, of the Company (the "Common Stock"). In the event the Company shall, at
any time after the issuance of any share or fraction of a share of Series B
Preferred Stock, make any distribution on the shares of Common Stock of the
Company, whether by way of a dividend or a reclassification of stock, a
recapitalization, reorganization or partial liquidation of the Company or
otherwise, which is payable in cash or any debt security, debt instrument, real
or personal property or any other property (other than cash dividends subject to
the immediately preceding sentence, a distribution of shares of Common Stock or
other capital stock of the Company or a distribution of rights or warrants to
acquire any such share, including any debt security






                                      2
<PAGE>
convertible into or exchangeable for any such share, at a price less than the
Fair Market Value (as hereinafter defined) of such share), then, and in each
such event, the Company shall simultaneously pay on each then outstanding share
of Series B Preferred Stock of the Company a distribution, in like kind, of 100
times such distribution paid on a share of Common Stock (subject to the
provisions for adjustment hereinafter set forth). The dividends and
distributions on the Series B Preferred Stock to which holders thereof are
entitled pursuant to the first and second sentences of this paragraph are
hereinafter referred to as "Dividends" and the multiple of such cash and
non-cash dividends on the Common Stock applicable to the determination of the
Dividends, which shall be 100 initially but shall be adjusted from time to time
as hereinafter provided, is hereinafter referred to as the "Dividend Multiple".
In the event the Company shall at any time after July 28, 1997 declare or pay
any dividend or make any distribution on Common Stock payable in shares of
Common Stock, or effect a subdivision or split or a combination, consolidation
or reverse split of the outstanding shares of Common Stock into a greater or
lesser number of shares of Common Stock, then in each such case the Dividend
Multiple thereafter applicable to the determination of the amount of Dividends
which holders of shares of Series B Preferred Stock shall be entitled to receive
shall be the Dividend Multiple applicable immediately






                                      3
<PAGE>
prior to such event multiplied by a fraction the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

            (B) The Company shall declare each Dividend at the same time it
declares any cash or non-cash dividend or distribution on the Common Stock in
respect of which a Dividend is required to be paid. No cash or non-cash dividend
or distribution on the Common Stock in respect of which a Dividend is required
to be paid shall be paid or set aside for payment on the Common Stock unless a
Dividend in respect of such dividend or distribution on the Common Stock shall
be simultaneously paid, or set aside for payment, on the Series B Preferred
Stock.

            Section 3.  Voting Rights.  The holders of shares of Series B 
Preferred Stock shall have the following voting rights:

            (A) Subject to the provisions for adjustment hereinafter set forth,
each share of Series B Preferred Stock shall entitle the holder thereof to 100
votes on all matters submitted to a vote of the holders of the Common Stock. The
number of votes which a holder of Series B Preferred Stock is entitled to cast,
as the same may be adjusted from time to time as hereinafter provided, is
hereinafter referred to as the "Vote Multiple". In the event the Company shall
at any time after July







                                      4
<PAGE>
28, 1997 declare or pay any dividend on Common Stock payable in shares of Common
Stock, or effect a subdivision or split or a combination, consolidation or
reverse split of the outstanding shares of Common Stock into a greater or lesser
number of shares of Common Stock, then in each such case the Vote Multiple
thereafter applicable to the determination of the number of votes per share to
which holders of shares of Series B Preferred Stock shall be entitled after such
event shall be the Vote Multiple immediately prior to such event multiplied by a
fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

            (B) Except as otherwise provided herein, in the Articles of
Incorporation or By-laws, the holders of shares of Series B Preferred Stock and
the holders of shares of Common Stock shall vote together as one class on all
matters submitted to a vote of stockholders of the Company.

            (C) In the event that Dividends on the Series B Preferred Stock for
four or more consecutive quarterly periods shall not have been declared and paid
or irrevocably set aside for payment, the holders of record of Preferred Stock
of the Company of all series (including the Series B Preferred Stock), other
than any series in respect of which such right is expressly







                                      5
<PAGE>
withheld by the Articles of Incorporation or the authorizing resolutions
included in any Certificate of Designations therefor, shall have the right, at
the next meeting of stockholders called for the election of directors, to elect
two members to the Board of Directors, which directors shall be in addition to
the number required by the By-laws prior to such event, to serve until the next
Annual Meeting and until their successors are elected and qualified or their
earlier resignation, removal or incapacity or until such earlier time as
Dividends upon the outstanding shares of Series B Preferred Stock shall have
been paid (or irrevocably set aside for payment) for four consecutive quarterly
periods. The holders of shares of Series B Preferred Stock shall continue to
have the right to elect directors as provided by the immediately preceding
sentence until Dividends upon the outstanding shares of Series B Preferred Stock
shall have been paid (or set aside for payment) for four consecutive quarterly
periods. Such directors may be removed and replaced by such stockholders, and
vacancies in such directorships may be filled only by such stockholders (or by
the remaining director elected by such stockholders, if there be one) in the
manner permitted by law; provided, however, that any such action by stockholders
shall be taken at a meeting of stockholders and shall not be taken by written
consent thereto.






                                      6
<PAGE>
            (D) Except as otherwise required by the Articles of Incorporation or
By-laws or set forth herein, holders of Series B Preferred Stock shall have no
other special voting rights and their consent shall not be required (except to
the extent they are entitled to vote with holders of Common Stock as set forth
herein) for the taking of any corporate action.

            Section 4.  Certain Restrictions.

            (A) Whenever Dividends on the Series B Preferred Stock for four or
more consecutive quarterly periods shall not have been declared and paid or
irrevocably set aside for payment and thereafter continuing until Dividends upon
the outstanding Series B Preferred Stock shall have been paid (or set aside for
payment) for four consecutive quarterly periods, and in addition to any and all
other rights which any holder of shares of Series B Preferred Stock may have in
such circumstances, the Company shall not

            (i) declare or pay dividends on, make any other distributions on, or
      redeem or purchase or otherwise acquire for consideration, any shares of
      stock ranking junior (either as to dividends or upon liquidation,
      dissolution or winding up) to the Series B Preferred Stock;

          (ii) declare or pay dividends on or make any other distributions on
      any shares of stock ranking on a parity as to dividends with the Series B
      Preferred Stock, unless






                                      7
<PAGE>
      dividends are paid ratably on the Series B Preferred Stock and all such
      parity stock on which dividends are payable or in arrears in proportion to
      the total amounts to which the holders of all such shares are then
      entitled if the full dividends accrued thereon were to be paid;

         (iii) except as permitted by subparagraph (iv) of this paragraph 4(A),
      redeem or purchase or otherwise acquire for consideration shares of any
      stock ranking on a parity (either as to dividends or upon liquidation,
      dissolution or winding up) with the Series B Preferred Stock, provided
      that the Company may at any time redeem, purchase or otherwise acquire
      shares of any such parity stock in exchange for shares of any stock of the
      Company ranking junior (both as to dividends and upon liquidation,
      dissolution or winding up) to the Series B Preferred Stock; or

          (iv) purchase or otherwise acquire for consideration any shares of
      Series B Preferred Stock, or any shares of stock ranking on a parity with
      the Series B Preferred Stock (either as to dividends or upon liquidation,
      dissolution or winding up), except in accordance with a purchase offer
      made to all holders of such shares upon such terms as the Board of
      Directors, after consideration of the respective annual dividend rates and
      other relative rights and preferences of the respective series and
      classes, shall determine in good







                                      8
<PAGE>
      faith will result in fair and equitable treatment among the respective
      series or classes.

            (B) The Company shall not permit any Subsidiary (as hereinafter
defined) of the Company to purchase or otherwise acquire for consideration any
shares of stock of the Company unless the Company could, under paragraph (A) of
this Section 4, purchase or otherwise acquire such shares at such time and in
such manner. A "Subsidiary" of the Company shall mean any corporation or other
entity of which securities or other ownership interests having ordinary voting
power sufficient to elect a majority of the board of directors of such
corporation or other entity or other persons performing similar functions are
beneficially owned, directly or indirectly, by the Company or by any corporation
or other entity that is otherwise controlled by the Company.

            (C) The Company shall not issue any shares of Series B Preferred
Stock except upon exercise of Rights issued pursuant to that certain Rights
Agreement dated as of June 16, 1997 between the Company and American Stock
Transfer & Trust Company, as Rights Agent, a copy of which is on file with the
Secretary of the Company at its principal executive office and shall be made
available to stockholders of record without charge upon written request therefor
addressed to said Secretary. Notwithstanding the foregoing sentence, nothing
contained in the provisions here-







                                      9

<PAGE>
of shall prohibit or restrict the Company from issuing for any purpose any
series of Preferred Stock with rights and privileges similar to, different from,
or greater than, those of the Series B Preferred Stock.

            Section 5. Reacquired Shares. Any shares of Series B Preferred Stock
purchased or otherwise acquired by the Company in any manner whatsoever shall be
retired and cancelled promptly after the acquisition thereof. All such shares
upon their retirement and cancellation shall become authorized but unissued
shares of Preferred Stock, without designation as to series, and such shares may
be reissued as part of a new series of Preferred Stock to be created by
resolution or resolutions of the Board of Directors.

            Section 6. Liquidation, Dissolution or Winding Up. Upon any
voluntary or involuntary liquidation, dissolution or winding up of the Company,
no distribution shall be made (i) to the holders of shares of stock ranking
junior (either as to dividends or upon liquidation, dissolution or winding up)
to the Series B Preferred Stock unless the holders of shares of Series B
Preferred Stock shall have received for each share of Series B Preferred Stock,
subject to adjustment as hereinafter provided, (A) $20,000 plus an amount equal
to accrued and unpaid dividends and distributions thereon to the date of such
payment or, (B) if greater than the amount specified in clause (i)(A) of this







                                      10
<PAGE>
sentence, an amount equal to 100 times the aggregate amount to be distributed
per share to holders of Common Stock, as the same may be adjusted as hereinafter
provided and (ii) to the holders of stock ranking on a parity upon liquidation,
dissolution or winding up with the Series B Preferred Stock, unless
simultaneously therewith distributions are made ratably on the Series B
Preferred Stock and all other shares of such parity stock in proportion to the
total amounts to which the holders of shares of Series B Preferred Stock are
entitled under clause (i)(A) of this sentence and to which the holders of such
parity shares are entitled, in each case upon such liquidation, dissolution or
winding up. The amount to which holders of Series B Preferred Stock may be
entitled upon liquidation, dissolution or winding up of the Company pursuant to
clause (i)(B) of the foregoing sentence is hereinafter referred to as the
"Participating Liquidation Amount" and the multiple of the amount to be
distributed to holders of shares of Common Stock upon the liquidation,
dissolution or winding up of the Company applicable pursuant to said clause to
the determination of the Participating Liquidation Amount, as said multiple may
be adjusted from time to time as hereinafter provided, is hereinafter referred
to as the "Liquidation Multiple". In the event the Company shall at any time
after June 28, 1997 declare or pay any dividend on Common Stock payable in
shares of Common Stock, or effect a subdivision





                                      11

<PAGE>
or split or a combination, consolidation or reverse split of the outstanding
shares of Common Stock into a greater or lesser number of shares of Common
Stock, then, in each such case, the Liquidation Multiple thereafter applicable
to the determination of the Participating Liquidation Amount to which holders of
Series B Preferred Stock shall be entitled after such event shall be the
Liquidation Multiple applicable immediately prior to such event multiplied by a
fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

            Section 7.  Certain Reclassifications and Other Events.

            (A)  In the event that holders of shares of Common
Stock of the Company receive after June 28, 1997 in respect of their shares of
Common Stock any share of capital stock of the Company (other than any share of
Common Stock of the Company), whether by way of reclassification,
recapitalization, reorganization, dividend or other distribution or otherwise (a
"Transaction"), then, and in each such event, the dividend rights, voting rights
and rights upon the liquidation, dissolution or winding up of the Company of the
shares of Series B Preferred Stock shall be adjusted so that after such event
the holders of Series B Preferred Stock shall be entitled, in respect of each





                                      12
<PAGE>
share of Series B Preferred Stock held, in addition to such rights in respect
thereof to which such holder was entitled immediately prior to such adjustment,
to (i) such additional dividends as equal the Dividend Multiple in effect
immediately prior to such Transaction multiplied by the additional dividends
which the holder of a share of Common Stock shall be entitled to receive by
virtue of the receipt in the Transaction of such capital stock, (ii) such
additional voting rights as equal the Vote Multiple in effect immediately prior
to such Transaction multiplied by the additional voting rights which the holder
of a share of Common Stock shall be entitled to receive by virtue of the receipt
in the Transaction of such capital stock and (iii) such additional distributions
upon liquidation, dissolution or winding up of the Company as equal the
Liquidation Multiple in effect immediately prior to such Transaction multiplied
by the additional amount which the holder of a share of Common Stock shall be
entitled to receive upon liquidation, dissolution or winding up of the Company
by virtue of the receipt in the Transaction of such capital stock, as the case
may be, all as provided by the terms of such capital stock.

            (B) In the event that holders of shares of Common Stock of the
Company receive after June 28, 1997 in respect of their shares of Common Stock
any right or warrant to purchase Common Stock (including as such a right, for
all purposes of this






                                      13
<PAGE>
paragraph, any security convertible into or exchangeable for Common Stock) at a
purchase price per share less than the Fair Market Value of a share of Common
Stock on the date of issuance of such right or warrant, then and in each such
event the dividend rights, voting rights and rights upon the liquidation,
dissolution or winding up of the Company of the shares of Series B Preferred
Stock shall each be adjusted so that after such event the Dividend Multiple, the
Vote Multiple and the Liquidation Multiple shall each be the product of the
Dividend Multiple, the Vote Multiple and the Liquidation Multiple, as the case
may be, in effect immediately prior to such event multiplied by a fraction the
numerator of which shall be the number of shares of Common Stock outstanding
immediately before such issuance of rights or warrants plus the maximum number
of shares of Common Stock which could be acquired upon exercise in full of all
such rights or warrants and the denominator of which shall be the number of
shares of Common Stock outstanding immediately before such issuance of rights or
warrants plus the number of shares of Common Stock which could be purchased, at
the Fair Market Value of the Common Stock at the time of such issuance, by the
maximum aggregate consideration payable upon exercise in full of all such rights
or warrants.

            (C) In the event that holders of shares of Common Stock of the
Company receive after June 28, 1997 in respect of





                                      14
<PAGE>
their shares of Common Stock any right or warrant to purchase capital stock of
the Company (other than shares of Common Stock), including as such a right, for
all purposes of this paragraph, any security convertible into or exchangeable
for capital stock of the Company (other than Common Stock), at a purchase price
per share less than the Fair Market Value of such shares of capital stock on the
date of issuance of such right or warrant, then and in each such event the
dividend rights, voting rights and rights upon liquidation, dissolution or
winding up of the Company of the shares of Series B Preferred Stock shall each
be adjusted so that after such event each holder of a share of Series B
Preferred Stock shall be entitled, in respect of each share of Series B
Preferred Stock held, in addition to such rights in respect thereof to which
such holder was entitled immediately prior to such event, to receive (i) such
additional dividends as equal the Dividend Multiple in effect immediately prior
to such event multiplied, first, by the additional dividends to which the holder
of a share of Common Stock shall be entitled upon exercise of such right or
warrant by virtue of the capital stock which could be acquired upon such
exercise and multiplied again by the Discount Fraction (as hereinafter defined)
and (ii) such additional voting rights as equal the Vote Multiple in effect
immediately prior to such event multiplied, first, by the additional voting
rights to which the holder of a share of Common Stock




                                      15
<PAGE>
shall be entitled upon exercise of such right or warrant by virtue of the
capital stock which could be acquired upon such exercise and multiplied again by
the Discount Fraction and (iii) such additional distributions upon liquidation,
dissolution or winding up of the Company as equal the Liquidation Multiple in
effect immediately prior to such event multiplied, first, by the additional
amount which the holder of a share of Common Stock shall be entitled to receive
upon liquidation, dissolution or winding up of the Company upon exercise of such
right or warrant by virtue of the capital stock which could be acquired upon
such exercise and multiplied again by the Discount Fraction. For purposes of
this paragraph, the "Discount Fraction" shall be a fraction the numerator of
which shall be the difference between the Fair Market Value of a share of the
capital stock subject to a right or warrant distributed to holders of shares of
Common Stock of the Company as contemplated by this paragraph immediately after
the distribution thereof and the purchase price per share for such share of
capital stock pursuant to such right or warrant and the denominator of which
shall be the Fair Market Value of a share of such capital stock immediately
after the distribution of such right or warrant.

            (D) For purposes of this Certificate of Designations, the "Fair
Market Value" of a share of capital stock of the Company (including a share of
Common Stock) on any date shall be





                                      16
<PAGE>
deemed to be the average of the daily closing price per share thereof over the
30 consecutive Trading Days (as such term is hereinafter defined) immediately
prior to such date; provided, however, that, in the event that such Fair Market
Value of any such share of capital stock is determined during a period which
includes any date that is within 30 Trading Days after (i) the ex-dividend date
for a dividend or distribution on stock payable in shares of such stock or
securities convertible into shares of such stock, or (ii) the effective date of
any subdivision, split, combination, consolidation, reverse stock split or
reclassifica- tion of such stock, then, and in each such case, the Fair Market
Value shall be appropriately adjusted by the Board of Directors of the Company
to take into account ex-dividend or post-effective date trading. The closing
price for any day shall be the last sale price, regular way, or, in case, no
such sale takes place on such day, the average of the closing bid and asked
prices, regular way (in either case, as reported in the applicable transaction
reporting system with respect to securities listed or admitted to trading on the
New York Stock Exchange), or, if the shares are not listed or admitted to
trading on the New York Stock Exchange, as reported in the applicable
transaction reporting system with respect to securities listed on the principal
national securities exchange on which the shares are listed or admitted to
trading or, if the shares are not listed or admitted




                                      17
<PAGE>
to trading on any national securities exchange, the last quoted price or, if not
so quoted, the average of the high bid and low asked prices in the
over-the-counter market, as reported by the National Association of Securities
Dealers, Inc. Automated Quotation System ("NASDAQ") or such other system then in
use, or if on any such date the shares 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 shares selected by the Board of Directors of
the Company. The term "Trading Day" shall mean a day on which the principal
national securities exchange on which the shares are listed or admitted to
trading is open for the transaction of business or, if the shares are not listed
or admitted to trading on any national securities exchange, on which the New
York Stock Exchange or such other national securities exchange as may be
selected by the Board of Directors of the Company is open. If the shares are not
publicly held or not so listed or traded on any day within the period of 30
Trading Days applicable to the determination of Fair Market Value thereof as
aforesaid, "Fair Market Value" shall mean the fair market value thereof per
share as determined in good faith by the Board of Directors of the Company. In
either case referred to in the foregoing sentence, the determination of Fair
Market Value shall be described in a statement filed with the Secretary of the
Company.

            Section 8. Consolidation, Merger, etc. In case the Company shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case each
outstanding share of Series B Preferred Stock shall at the same time be
similarly exchanged for or changed into the aggregate amount of stock,
securities, cash and/or other property (payable in like kind), as the case may
be, for which or into which each share of Common Stock is changed or exchanged
multiplied by the highest of the Vote Multiple, the Dividend Multiple or the
Liquidation Multiple in effect immediately prior to such event.

            Section 9.  Effective Time of Adjustments.

            (A)  Adjustments to the Series B Preferred Stock
required by the provisions hereof shall be effective as of the time at which the
event requiring such adjustments occurs.

            (B) The Company shall give prompt written notice to each holder of a
share of Series B Preferred Stock of the effect of any adjustment to the voting
rights, dividend rights or rights upon liquidation, dissolution or winding up of
the Company of such shares required by the provisions hereof. Notwithstanding
the foregoing sentence, the failure of the Company to give such notice shall not
affect the validity of or the force or effect of or the requirement for such
adjustment.

            Section 10. No Redemption. The shares of Series B Preferred Stock
shall not be redeemable at the option of the Company or any holder thereof.
Notwithstanding the foregoing sentence of this Section, the Company may acquire
shares of Series B Preferred Stock in any other manner permitted by law, the
provisions hereof and the Restated Certificate of Incorporation of the Company.

            Section 11. Ranking. Unless otherwise provided in the Certificate of
Incorporation of the Company or a Certificate of Designations relating to a
subsequent series of preferred stock of the Company, the Series B Preferred
Stock shall rank junior to all other series of the Company's preferred stock as
to the payment of dividends and the distribution of assets on liquidation,
dissolution or winding up and senior to the Common Stock.

            Section 12. Amendment. The provisions hereof and the Certificate of
Incorporation of the Company shall not be amended in any manner which would
adversely affect the rights, privileges or powers of the Series B Preferred
Stock without, in addition to any other vote of stockholders required by law,
the affirmative vote of the holders of two-thirds or more of the outstanding
shares of Series B Preferred Stock, voting together as a single class.
