Item 1.           Description of Securities to be Registered.

                  On April 22, 1997, pursuant to a Preferred Shares Rights
Agreement (the "Rights Agreement") between Cardiac Pathways Corporation (the
"Company") and Norwest Bank Minnesota, N.A., as Rights Agent (the "Rights
Agent"), the Company's Board of Directors declared a dividend of one right (a
"Right") to purchase one one-thousandth of a share of the Company's Series A
Participating Preferred Stock, $.001 par value per share ("Series A Preferred")
for each outstanding share of Common Stock, $.001 par value per share ("Common
Shares"), of the Company. The dividend is payable on May 23, 1997 (the "Record
Date") to stockholders of record as of the close of business on April 30, 1997.
Each Right entitles the registered holder to purchase from the Company one
one-thousandth of a share of Series A Preferred at an exercise price of $125.00
(the "Purchase Price"), subject to adjustment.

         The following summary of the principal terms of the Rights Agreement is
a general description only and is subject to the detailed terms and conditions
of the Rights Agreement. A copy of the Rights Agreement is attached as Exhibit 1
to this Registration Statement and is incorporated herein by reference.




                                       -2-

<PAGE>   3
Rights Evidenced by Common Share Certificates

         The Rights will not be exercisable until the Distribution Date (defined
below). Certificates for the Rights ("Rights Certificates") will not be sent to
stockholders and the Rights will attach to and trade only together with the
Common Shares. Accordingly, Common Share certificates outstanding on the Record
Date will evidence the Rights related thereto, and Common Share certificates
issued after the Record Date will contain a notation incorporating the Rights
Agreement by reference. Until the Distribution Date (or earlier redemption or
expiration of the Rights), the surrender or transfer of any certificates for
Common Shares, outstanding as of the Record Date, even without notation or a
copy of the Summary of Rights being attached thereto, will also constitute the
transfer of the Rights associated with the Common Shares represented by such
certificate.

Distribution Date

         The Rights will separate from the Common Shares, Rights Certificates
will be issued and the Rights will become exercisable upon the earlier of: (i)
10 days (or such later date as may be determined by a majority of the Board of
Directors) following a public announcement that a person or group of affiliated
or associated persons (an "Acquiring Person") has acquired, or obtained the
right to acquire, beneficial ownership of 15% or more of the outstanding Common
Shares, or (ii) 10 business days (or such later date as may be determined by a
majority of the Board of Directors) following the commencement of, or
announcement of an intention to make, a tender offer or exchange offer the


                                      -3-
<PAGE>   4
consummation of which would result in the beneficial ownership by a person or
group of 15% or more of the outstanding Common Shares. The earlier of such dates
is referred to as the "Distribution Date."

Issuance of Rights Certificates; Expiration of Rights

         As soon as practicable following the Distribution Date, separate Rights
Certificates will be mailed to holders of record of the Common Shares as of the
close of business on the Distribution Date and such separate Rights Certificates
alone will evidence the Rights from and after the Distribution Date. The Rights
will expire on the earliest of (i) April 21, 2007 (the "Final Expiration Date")
or (ii) redemption or exchange of the Rights as described below.

Initial Exercise of the Rights

         Following the Distribution Date, and until one of the further events
described below, holders of the Rights will be entitled to receive, upon the
exercise and payment of the Purchase Price, one one-thousandth of a share of the
Series A Preferred.

Right to Buy Company Common Shares

         Unless the Rights are earlier redeemed, in the event that an Acquiring
Person becomes the beneficial owner of 15% or more of the Company's Common
Shares then outstanding, then proper provision will be made so that each holder
of a Right which has not theretofore been exercised (other than Rights
beneficially owned by the Acquiring Person or any affiliate of the Acquiring
Person, which will thereafter

                                      -4-
<PAGE>   5
be void) will thereafter have the right to receive, upon exercise, Common Shares
having a value equal to two times the Purchase Price. In the event that the
Company does not have sufficient Common Shares available for all Rights to be
exercised, or the Board decides that such action is necessary and not contrary
to the interests of Rights holders, the Company may instead substitute cash,
assets or other securities for the Common Shares for which the Rights would have
been exercisable.

Right to Buy Acquiring Company Stock

         Similarly, unless the Rights are earlier redeemed, in the event that,
after an Acquiring Person becomes the beneficial owner of 15% or more of the
Company's Common Shares then outstanding, (i) the Company is acquired in a
merger or other business combination transaction, or (ii) 50% or more of the
Company's consolidated assets or earning power are sold (other than in
transactions in the ordinary course of business), proper provision must be made
so that each holder of a Right which has not theretofore been exercised (other
than Rights beneficially owned by the Acquiring Person or any affiliate of the
Acquiring Person, which will thereafter be void) will thereafter have the right
to receive, upon exercise, shares of common stock of the acquiring company
having a value equal to two times the Purchase Price.

Exchange Provision

         At any time after the acquisition by an Acquiring Person of beneficial
ownership of 15% or more of the Company's outstanding Common Shares and prior to
the acquisition by any person or entity of beneficial ownership of 50% or more
of the Company's outstanding Common Shares, the Board of 

                                      -5-
<PAGE>   6
Directors of the Company may exchange the Rights (other than Rights owned by the
Acquiring Person), in whole or in part, at an exchange ratio of one Common Share
per Right.

Redemption

         At any time on or prior to the close of business on the earlier of (i)
the 10th day following the acquisition by an Acquiring Person of beneficial
ownership of 15% or more of the Company's Common Shares or such later date as
may be determined by a majority of the Board of Directors and publicly announced
by the Company, or (ii) the Final Expiration Date of the Rights, the Company may
redeem the Rights in whole, but not in part, at a price of $0.01 per Right.

Adjustments to Prevent Dilution

         The Purchase Price payable, the number of Rights, and the number of
Series A Preferred or Common Shares or other securities or property issuable
upon exercise of the Rights are subject to adjustment from time to time in
connection with the dilutive issuances by the Company as set forth in the Rights
Agreement. With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price.

                                      -6-
<PAGE>   7
Cash Paid Instead of Issuing Fractional Shares

         No fractional portion less than integral multiples of one Common Share
or one one-thousandth of a share of Series A Preferred will be issued upon
exercise of a Right and in lieu thereof, an adjustment in cash will be made
based on the market price of the security to be so issued on the last trading
date prior to the date of exercise.

No Stockholders' Rights Prior to Exercise

         Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company (other than any rights resulting from
such holder's ownership of Common Shares), including, without limitation, the
right to vote or to receive dividends.

Amendment of Rights Agreement

         The provisions of the Rights Agreement may be supplemented or amended
by the Board of Directors in any manner prior to the close of business on the
date the Rights separate from the Common Shares and become exercisable. After
such date, the provisions of the Rights Agreement may be amended by the Board in
order to cure any ambiguity, defect or inconsistency, to make changes which do
not adversely affect the interests of holders of Rights (excluding the interests
of any Acquiring Person), or to shorten or lengthen any time period under the
Rights Agreement; provided, however, that

                                      -7-
<PAGE>   8
no amendment to adjust the time period governing redemption shall be made at
such time as the Rights are not redeemable.

Rights and Preferences of the Series A Preferred

         Series A Preferred purchasable upon exercise of the Rights will not be
redeemable. Each share of Series A Preferred will be entitled to an aggregate
dividend of 1,000 times the dividend declared per Common Share. In the event of
liquidation, the holders of the Series A Preferred will be entitled to 1,000
times the amount paid per Common Share plus an amount equal to accrued and
unpaid dividends and distributions thereon, whether or not declared, to the date
of such payment. Each share of Series A Preferred will have 1,000 votes, voting
together with the Common Shares. These rights are protected by customary
anti-dilution provisions.

         Because of the nature of the dividend, liquidation and voting rights of
the shares of Series A Preferred, the value of the one one-thousandth interest
in a share of Series A Preferred purchasable upon exercise of each Right should
approximate the value of one Common Share.

Certain Anti-takeover Effects

         The Rights approved by the Board are designed to protect and maximize
the value of the outstanding equity interests in the Company in the event of an
unsolicited attempt by an acquiror to take over the Company, in a manner or on
terms not approved by the Board of Directors. Takeover attempts

                                      -8-
<PAGE>   9
frequently include coercive tactics to deprive the Company's Board of Directors
and its stockholders of any real opportunity to determine the destiny of the
Company. The Rights have been declared by the Board in order to deter such
tactics, including a gradual accumulation of shares in the open market of a 15%
or greater position to be followed by a merger or a partial or two-tier tender
offer that does not treat all stockholders equally. These tactics unfairly
pressure stockholders, squeeze them out of their investment without giving them
any real choice and deprive them of the full value of their shares.

         The Rights are not intended to prevent a takeover of the Company and
will not do so. The Rights may be redeemed by the Company at $0.01 per Right
within ten days (or such later date as may be determined by a majority of the
Continuing Directors) after the accumulation of 15% or more of the Company's
shares by a single acquiror or group. Accordingly, the Rights should not
interfere with any merger or business combination approved by the Board of
Directors.

         Issuance of the Rights does not in any way weaken the financial
strength of the Company or interfere with its business plans. The issuance of
the Rights themselves has no dilutive effect, will not affect reported earnings
per share, should not be taxable to the Company or to its stockholders, and will
not change the way in which the Company's shares are presently traded. The
Company's Board of Directors believes that the Rights represent a sound and
reasonable means of addressing the complex issues of corporate policy created by
the current takeover environment.

         However, the Rights may have the effect of rendering more difficult or
discouraging an acquisition of the Company deemed undesirable by the Board of
Directors. The Rights may cause substantial

                                      -9-
<PAGE>   10
dilution to a person or group that attempts to acquire the Company on terms or
in a manner not approved by the Company's Board of Directors, except pursuant to
an offer conditioned upon the negation, purchase or redemption of the Rights.

                                RIGHTS AGREEMENT


         Agreement, dated as of April 22, 1997, between Cardiac Pathways
Corporation, a Delaware corporation, and Norwest Bank Minnesota, N.A.

         On April 22, 1997 (the "Rights Dividend Declaration Date"), the Board
of Directors of the Company authorized and declared a dividend of one Preferred
Share Purchase Right (a "Right") for each Common Share (as hereinafter defined)
of the Company outstanding as of the Close of Business (as hereinafter defined)
on April 30, 1997 (the "Record Date"), each Right representing the right to
purchase one one-thousandth of a share of Series A Participating Preferred Stock
(as such number may be adjusted pursuant to the provisions of this Agreement),
having the rights, preferences and privileges set forth in the form of
Certificate of Designations of Rights, Preferences and Privileges of Series A
Participating Preferred Stock attached hereto as Exhibit A, upon the terms and
subject to the conditions herein set forth, and further authorized and directed
the issuance of one Right (as such number may be adjusted pursuant to the
provisions of this Agreement) with respect to each Common Share that shall
become outstanding between the Record Date and the earlier of the Distribution
Date and the Expiration Date (as such terms are hereinafter defined), and in
certain circumstances after the Distribution Date.

         NOW, THEREFORE, in consideration of the promises 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 have the meanings indicated:

                  (a) "Acquiring Person" shall mean any Person who or which,
together with all Affiliates and Associates of such Person, shall be the
Beneficial Owner of 15% or more of the Common Shares then outstanding, but shall
not include the Company, any Subsidiary of the Company or any employee benefit
plan of the Company or of any Subsidiary of the Company, or any entity holding
Common Shares for or pursuant to the terms of any such plan. Notwithstanding the
foregoing, no Person shall be deemed to be an Acquiring Person as the result of
an acquisition of Common Shares by the Company which, by reducing the number of
shares outstanding, increases the proportionate number of shares beneficially
owned by such Person to 15% or more of the Common Shares of the Company then
outstanding; provided, however, that if a Person shall become the Beneficial
Owner of 15% or more of the Common Shares of the Company then outstanding by
reason of share purchases by the Company and shall, after such share purchases
by the Company, become the Beneficial Owner of any additional Common Shares of
the Company (other than pursuant to a dividend or distribution paid or made by
the Company on the outstanding Common Shares in Common Shares or pursuant to a
split or subdivision of the outstanding Common Shares), then such Person shall
be deemed to be an Acquiring Person unless upon becoming the Beneficial Owner of
such additional Common Shares of the Company such Person does not beneficially
own 15% or more of the Common Shares of the Company then outstanding.
Notwithstanding the foregoing, (i) if the Company's Board of Directors
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 (including, without limitation, because (A) such


<PAGE>   5
Person was unaware that it beneficially owned a percentage of the Common Shares
that would otherwise cause such Person to be an "Acquiring Person," as defined
pursuant to the foregoing provisions of this paragraph (a), or (B) such Person
was aware of the extent of the Common Shares it beneficially owned but had no
actual knowledge of the consequences of such beneficial ownership under this
Agreement) and without any intention of changing or influencing control of the
Company, and if such Person divested or divests as promptly as practicable a
sufficient number of Common Shares so that such Person would no longer be an
"Acquiring Person," as defined pursuant to the foregoing provisions of this
paragraph (a), then such Person shall not be deemed to be or to have become an
"Acquiring Person" for any purposes of this Agreement; and (ii) if, as of the
date hereof, any Person is the Beneficial Owner of 15% or more of the Common
Shares outstanding, such Person shall not be or become an "Acquiring Person," as
defined pursuant to the foregoing provisions of this paragraph (a), unless and
until such time as such Person shall become the Beneficial Owner of additional
Common Shares (other than pursuant to a dividend or distribution paid or made by
the Company on the outstanding Common Shares in Common Shares or pursuant to a
split or subdivision of the outstanding Common Shares), unless, upon becoming
the Beneficial Owner of such additional Common Shares, such Person is not then
the Beneficial Owner of 15% or more of the Common Shares then outstanding.

                  (b)      "Adjustment Fraction" shall have the meaning set 
forth in Section 11(a)(i) hereof.

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

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

                           (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 Rule 13d-3 thereunder (or any
comparable or successor law or regulation);

                           (ii)     which such Person or any of such Person's
Affiliates or Associates has (A) the right to acquire (whether such right is
exercisable immediately or only after the passage of time) pursuant to any
agreement, arrangement or understanding (other than customary agreements with
and between underwriters and selling group members with respect to a bona fide
public offering of securities), or upon the exercise of conversion rights,
exchange rights, rights (other than the Rights), warrants or options, or
otherwise; provided, however, that a Person shall not be deemed pursuant to this
Section 1(d)(ii)(A) to be the Beneficial Owner of, or to beneficially own, (1)
securities tendered pursuant to a tender or exchange offer made by or on behalf
of such Person or any of such Person's Affiliates or Associates until such
tendered securities are accepted for purchase or exchange, or (2) securities
which a Person or any of such Person's Affiliates or Associates may be deemed to
have the right to acquire pursuant to any merger or other acquisition agreement
between the Company and such Person (or one or more of its Affiliates or
Associates) if such agreement has been approved by the Board of Directors of the
Company prior to there being an Acquiring Person; or (B) the right to vote
pursuant to any agreement, arrangement or understanding; provided, however, that
a Person shall not be deemed the

                                      -2-
<PAGE>   6
Beneficial Owner of, or to beneficially own, any security under this Section
1(d)(ii)(B) if the agreement, arrangement or understanding to vote such security
(1) arises solely from a revocable proxy or consent given to such Person in
response to a public proxy or consent solicitation made pursuant to, and in
accordance with, the applicable rules and regulations of the Exchange Act and
(2) is not also then reportable on Schedule 13D under the Exchange Act (or any
comparable or successor report); or

                           (iii)    which are beneficially owned, directly or
indirectly, by any other Person (or any Affiliate or Associate thereof) with
which such Person or any of such Person's Affiliates or Associates has any
agreement, arrangement or understanding, whether or not in writing (other than
customary agreements with and between underwriters and selling group members
with respect to a bona fide public offering of securities) for the purpose of
acquiring, holding, voting (except to the extent contemplated by the proviso to
Section 1(d)(ii)(B)) or disposing of any securities of the Company; provided,
however, that in no case shall an officer or director of the Company be deemed
(x) the Beneficial Owner of any securities beneficially owned by another officer
or director of the Company solely by reason of actions undertaken by such
persons in their capacity as officers or directors of the Company or (y) the
Beneficial Owner of securities held of record by the trustee of any employee
benefit plan of the Company or any Subsidiary of the Company for the benefit of
any employee of the Company or any Subsidiary of the Company, other than the
officer or director, by reason of any influence that such officer or director
may have over the voting of the securities held in the plan.

                  (e) "Business Day" shall mean any day other than a Saturday,
Sunday or a day on which banking institutions in New York are authorized or
obligated by law or executive order to close.

                  (f) "Close of Business" on any given date shall mean 5:00

a Business Day it shall mean 5:00 P.M., California time, on the next succeeding
Business Day.

                  (g) "Common Shares" when used with reference to the Company
shall mean the shares of Common Stock of the Company, $.001 par value. Common
Shares when used with reference to any Person other than the Company shall mean
the capital stock (or equity interest) with the greatest voting power of such
other Person or, if such other Person is a Subsidiary of another Person, the
Person or Persons which ultimately control such first-mentioned Person.

                  (h)      "Common Stock Equivalents" shall have the meaning

those made pursuant to Section 11(a)(iii) hereof, shall mean the average of the
daily closing prices per share of such Security for the thirty (30) consecutive
Trading Days immediately prior to such date, and for purposes of computations
made pursuant to Section 11(a)(iii) hereof, the Current Per Share Market Price
of any Security on any date shall be deemed

                                      -3-
<PAGE>   7
to be the average of the daily closing prices per share of such Security for the
ten (10) consecutive Trading Days immediately prior to such date; provided,
however, that in the event that the Current Per Share Market Price of the
Security is determined during a period following the announcement by the issuer
of such Security of (i) a dividend or distribution on such Security payable in
shares of such Security or securities convertible into such shares or (ii) any
subdivision, combination or reclassification of such Security, and prior to the
expiration of the applicable thirty (30) Trading Day or ten (10) Trading Day
period, after the ex-dividend date for such dividend or distribution, or the
record date for such subdivision, combination or reclassification, then, and in
each such case, the Current Per Share Market Price shall be appropriately
adjusted to reflect the current market price per share equivalent of such
Security. The closing price for each day shall be the last sale price, regular
way, or, in case no such sale takes place on such day, the average of the
closing bid and asked prices, regular way, in either case as reported in the
principal consolidated transaction reporting system with respect to securities
listed or admitted to trading on the New York Stock Exchange or, if the Security
is not listed or admitted to trading on the New York Stock Exchange, as reported
in the principal consolidated transaction reporting system with respect to
securities listed on the principal national securities exchange on which the
Security is listed or admitted to trading or, if the Security is not listed or
admitted to trading on any national securities exchange, the last sale price or,
if such last sale price is not reported, the average of the high bid and low
asked prices in the over-the-counter market, as reported by Nasdaq or such other
system then in use, or, if on any such date the Security is not quoted by any
such organization, the average of the closing bid and asked prices as furnished
by a professional market maker making a market in the Security selected by the
Board of Directors of the Company. If on any such date no market maker is making
a market in the Security, the fair value of such shares on such date as
determined in good faith by the Board of Directors of the Company shall be used.
If the Preferred Shares are not publicly traded, the Current Per Share Market
Price of the Preferred Shares shall be conclusively deemed to be the Current Per
Share Market Price of the Common Shares as determined pursuant to this Section
1(j), as appropriately adjusted to reflect any stock split, stock dividend or
similar transaction occurring after the date hereof, multiplied by 1,000. If the
Security is not publicly held or so listed or traded, Current Per Share Market
Price shall mean the fair value per share as determined in good faith by the
Board of Directors of the Company, whose determination shall be described in a
statement filed with the Rights Agent and shall be conclusive for all purposes.

plan of the Company or of any Subsidiary of the Company, or any Person or entity
organized, appointed or established by the Company for or pursuant to the terms
of any such plan) is first published or sent or given within the meaning of Rule
14d-2(a) of the General Rules and Regulations under the Exchange Act, if,
assuming the successful consummation thereof, such Person would be an Acquiring
Person.

         Section 2.  Appointment of Rights Agent. The Company hereby appoints
the Rights Agent to act as agent for the Company and the holders of the Rights
(who, in accordance with Section 3 hereof, shall prior to the Distribution Date
also be the holders of the Common Shares) in accordance with the terms and
conditions hereof, and the Rights Agent hereby accepts such appointment. The
Company may from time to time appoint such co-Rights Agents as it may deem
necessary or desirable.

         Section 3.  Issuance of Rights Certificates.

                (a) Until the Distribution Date, (i) the Rights will be
evidenced (subject to the provisions of Sections 3(b) and 3(c) hereof) by the
certificates for Common Shares registered in the names of the holders thereof
(which certificates shall also be deemed to be Rights Certificates) and not by
separate Rights Certificates and (ii) the right to receive Rights Certificates
will be transferable only in connection with the transfer of Common Shares.
Until the earlier of the Distribution Date or the Expiration Date, the surrender
for transfer of certificates for Common Shares shall also constitute the
surrender for transfer of the Rights associated with the Common Shares
represented thereby. 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, postage-prepaid mail, to each record holder of Common
Shares as of the Close of Business on the Distribution Date, at the address of
such holder shown on the records of the Company, a Rights Certificate evidencing
one Right for each Common Share so held, subject to adjustment as provided
herein. In the event that an adjustment in the number of Rights per Common Share
has been made pursuant to Section 11 hereof, then at the time of distribution of
the Rights Certificates, the Company shall make the necessary and appropriate
rounding adjustments (in accordance with Section 14(a) hereof) so that Rights
Certificates representing only whole numbers of Rights are distributed and cash
is paid in lieu of any fractional Rights. As of the Distribution Date, the
Rights will be evidenced solely by such Rights Certificates and may be
transferred by the transfer of the Rights Certificates as permitted hereby,
separately and apart from any transfer of Common Shares, and the holders of such
Rights Certificates as listed in the records of the Company or any transfer
agent or registrar for the Rights shall be the record holders thereof.

                (b) On the Record Date or as soon as practicable thereafter,
the Company will send a copy of the Summary of Rights by first-class,
postage-prepaid mail, to each record holder of Common Shares as of the Close of
Business on the Record Date, at the address of such holder shown on the records
of the Company's transfer agent and registrar. With respect to certificates for
Common Shares outstanding as of the Record Date, until the Distribution Date,
the Rights will be evidenced by such certificates registered in the names of the
holders thereof together with the Summary of Rights. Until the Distribution Date
(or, if earlier, the Expiration Date), the surrender for transfer of any
certificate for Common Shares outstanding on the Record Date, with or without a
copy of the Summary of Rights, shall also constitute the transfer of the Rights
associated with the Common Shares represented thereby.

                (c) Unless the Board of Directors by resolution adopted at or
before the time of the issuance of any Common Shares specifies to the contrary,
Rights shall be issued in respect of all Common Shares that are issued after the
Record Date but prior to the earlier of the Distribution Date or the Expiration
Date or, in certain circumstances provided in Section 22 hereof, after the
Distribution Date.

                                      -7-

Certificates representing such Common Shares shall also be deemed to be
certificates for Rights, and shall bear the following legend:

         THIS CERTIFICATE ALSO EVIDENCES AND ENTITLES THE HOLDER HEREOF TO
         CERTAIN RIGHTS AS SET FORTH IN A RIGHTS AGREEMENT BETWEEN CARDIAC
         PATHWAYS CORPORATION AND NORWEST BANK MINNESOTA, N.A., AS THE RIGHTS
         AGENT, DATED AS OF APRIL 22, 1997, (THE "RIGHTS AGREEMENT"), THE TERMS
         OF WHICH ARE HEREBY INCORPORATED HEREIN BY REFERENCE AND A COPY OF
         WHICH IS ON FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF CARDIAC PATHWAYS
         CORPORATION. UNDER CERTAIN CIRCUMSTANCES, AS SET FORTH IN THE RIGHTS
         AGREEMENT, SUCH RIGHTS WILL BE EVIDENCED BY SEPARATE CERTIFICATES AND
         WILL NO LONGER BE EVIDENCED BY THIS CERTIFICATE. CARDIAC PATHWAYS
         CORPORATION WILL MAIL TO THE HOLDER OF THIS CERTIFICATE A COPY OF THE
         RIGHTS AGREEMENT WITHOUT CHARGE AFTER RECEIPT OF A WRITTEN REQUEST
         THEREFOR. UNDER CERTAIN CIRCUMSTANCES SET FORTH IN THE RIGHTS
         AGREEMENT, RIGHTS ISSUED TO, OR HELD BY, ANY PERSON WHO IS, WAS OR
         BECOMES AN ACQUIRING PERSON OR ANY AFFILIATE OR ASSOCIATE THEREOF (AS
         SUCH TERMS ARE DEFINED IN THE RIGHTS AGREEMENT), WHETHER CURRENTLY HELD
         BY OR ON BEHALF OF SUCH PERSON OR BY ANY SUBSEQUENT HOLDER, MAY BECOME
         NULL AND VOID.

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

                    (d) In the event that the Company purchases or acquires any
Common Shares after the Record Date but prior to the Distribution Date, any
Rights associated with such Common Shares shall be deemed canceled and retired
so that the Company shall not be entitled to exercise any Rights associated with
the Common Shares which are no longer outstanding.

         Section 4. Form of Rights Certificates.

                    (a) The Rights Certificates (and the forms of election to
purchase Common Shares and of assignment to be printed on the reverse thereof)
shall be substantially in the form of Exhibit B hereto and may have such marks
of identification or designation and such legends, summaries or endorsements
printed thereon as the Company may deem appropriate and as are not inconsistent
with the provisions of this Agreement, or as may be required to comply with any
applicable law or with any rule or regulation made pursuant thereto or with any
rule or regulation of any stock exchange or a national market system, on which
the Rights may from time to time be listed or included, or to conform to usage.
Subject to the provisions of Section 11 and Section 22 hereof, the Rights
Certificates, whenever distri-

                                      -8-
<PAGE>   12
buted, shall be dated as of the Record Date (or in the case of Rights issued
with respect to Common Shares issued by the Company after the Record Date, as of
the date of issuance of such Common Shares) and on their face shall entitle the
holders thereof to purchase such number of one-thousandths of a Preferred Share
as shall be set forth therein at the price set forth therein (such exercise
price per one one-thousandth of a Preferred Share being hereinafter referred to
as the "Exercise Price" and the aggregate Exercise Price of all Preferred Shares
issuable upon exercise of one Right being hereinafter referred to as the "Total
Exercise Price"), but the number and type of securities purchasable upon the
exercise of each Right and the Exercise Price shall be subject to adjustment as
provided herein.

                    (b) Any Rights Certificate issued pursuant to Section 3(a)
or Section 22 hereof that represents Rights beneficially owned by: (i) an
Acquiring Person or any Associate or Affiliate of an Acquiring Person, (ii) a
transferee of an Acquiring Person (or of any such Associate or Affiliate) who
becomes a transferee after the Acquiring Person becomes such or (iii) a
transferee of an Acquiring Person (or of any such Associate or Affiliate) who
becomes a transferee prior to or concurrently with the Acquiring Person becoming
such and receives such Rights pursuant to either (A) a transfer (whether or not
for consideration) from the Acquiring Person to holders of equity interests in
such Acquiring Person or to any Person with whom such Acquiring Person has any
continuing agreement, arrangement or understanding regarding the transferred
Rights or (B) a transfer which the Company's Board of Directors has determined
is part of a plan, arrangement or understanding which has as a primary purpose
or effect avoidance of Section 7(e) hereof, and any Rights Certificate issued
pursuant to Section 6 or Section 11 hereof upon transfer, exchange, replacement
or adjustment of any other Rights Certificate referred to in this sentence,
shall contain (to the extent feasible) the following legend:

         THE RIGHTS REPRESENTED BY THIS RIGHTS CERTIFICATE ARE OR WERE
         BENEFICIALLY OWNED BY A PERSON WHO WAS OR BECAME AN ACQUIRING PERSON OR
         AN AFFILIATE OR ASSOCIATE OF AN ACQUIRING PERSON (AS SUCH TERMS ARE
         DEFINED IN THE RIGHTS AGREEMENT). ACCORDINGLY, THIS RIGHTS CERTIFICATE
         AND THE RIGHTS REPRESENTED HEREBY MAY BECOME NULL AND VOID IN THE
         CIRCUMSTANCES SPECIFIED IN SECTION 7(e) OF THE RIGHTS AGREEMENT.

         Section 5. Countersignature and Registration.

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

                                      -9-
<PAGE>   13
on behalf of the Company by any person who, at the actual date of the execution
of such Rights Certificate, shall be a proper officer of the Company to sign
such Rights Certificate, although at the date of the execution of this Rights
Agreement any such person was not such an officer.

                    (b) Following the Distribution Date, the Rights Agent will
keep or cause to be kept, at its office designated for such purposes, books for
registration and transfer of the Rights Certificates issued hereunder. Such
books shall show the names and addresses of the respective holders of the Rights
Certificates, the number of Rights evidenced on its face by each of the Rights
Certificates and the date of each of the Rights Certificates.

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

                    (a) Subject to the provisions of Sections 7(e), 14 and 24
hereof, at any time after the Close of Business on the Distribution Date, and at
or prior to the Close of Business on the Expiration Date, any Rights Certificate
or Rights Certificates may be transferred, split up, combined or exchanged for
another Rights Certificate or Rights Certificates, entitling the registered
holder to purchase a like number of one-thousandths of a Preferred Share (or,
following a Triggering Event, other securities, cash or other assets, as the
case may be) as the Rights Certificate or Rights Certificates surrendered then
entitled such holder to purchase. Any registered holder desiring to transfer,
split up, combine or exchange any Rights Certificate or Rights Certificates
shall make such request in writing delivered to the Rights Agent, and shall
surrender the Rights Certificate or Rights Certificates to be transferred,
split up, combined or exchanged at the office of the Rights Agent designated for
such purpose. Neither the Rights Agent nor the Company shall be obligated to
take any action whatsoever with respect to the transfer of any such surrendered
Rights Certificate until the registered holder shall have completed and signed
the certificate contained in the form of assignment on the reverse side of such
Rights Certificate and shall have provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or
Associates thereof as the Company shall reasonably request. Thereupon the Rights
Agent shall, subject to Sections 7(e), 14 and 24 hereof, countersign and deliver
to the person entitled thereto a Rights Certificate or Rights Certificates, as
the case may be, as so requested. The Company may require payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer, split up, combination or exchange of Rights
Certificates.

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

         Section 7. Exercise of Rights; Exercise Price; Expiration Date of
Rights.

                    (a) Subject to Sections 7(e), 23(b) and 24(b) hereof, the
registered holder of any Rights Certificate may exercise the Rights evidenced
thereby (except as otherwise provided herein) in whole or in part at any time
after the Distribution Date and prior to the Close of Business on the Expiration
Date by surrender of the Rights Certificate, with the form of election to
purchase on the reverse side thereof duly executed, to the Rights Agent at the
office of the Rights Agent designated for such purpose, together with payment of
the Exercise Price for each one-thousandth of a Preferred Share (or, following a
Triggering Event, other securities, cash or other assets as the case may be) as
to which the Rights are exercised.

                    (b) The Exercise Price for each one-thousandth of a
Preferred Share issuable pursuant to the exercise of a Right shall initially be
One Hundred Twenty-Five Dollars ($125.00), shall be subject to adjustment from
time to time as provided in Sections 11 and 13 hereof and shall be payable in
lawful money of the United States of America in accordance with paragraph (c)
below.

                    (c) Upon receipt of a Rights Certificate representing
exercisable Rights, with the form of election to purchase duly executed,
accompanied by payment of the Exercise Price for the number of one-thousandths
of a Preferred Share (or, following a Triggering Event, other securities, cash
or other assets as the case may be) to be purchased and an amount equal to any
applicable transfer tax required to be paid by the holder of such Rights
Certificate in accordance with Section 9(e) hereof, the Rights Agent shall,
subject to Section 20(k) hereof, thereupon promptly (i) (A) requisition from any
transfer agent of the Preferred Shares (or make available, if the Rights Agent
is the transfer agent for the Preferred Shares) a certificate or certificates
for the number of one-thousandths of a Preferred Share (or, following a
Triggering Event, other securities, cash or other assets as the case may be) to
be purchased and the Company hereby irrevocably authorizes its transfer agent to
comply with all such requests or (B) if the Company shall have elected to
deposit the total number of one-thousandths of a Preferred Share (or, following
a Triggering Event, other securities, cash or other assets as the case may be)
issuable upon exercise of the Rights hereunder with a depositary agent,
requisition from the depositary agent depositary receipts representing such
number of one-thousandths of a Preferred Share (or, following a Triggering
Event, other securities, cash or other assets as the case may be) as are to be
purchased (in which case certificates for the Preferred Shares (or, following a
Triggering Event, other securities, cash or other assets as the case may be)
represented by such receipts shall be deposited by the transfer agent with the
depositary agent) and the Company hereby directs the depositary agent to comply
with such request, (ii) when appropriate, requisition from the Company the
amount of cash to be paid in lieu of issuance of fractional shares in accordance
with Section 14 hereof, (iii) after receipt of such certificates or depositary
receipts, cause the same to be delivered to or upon the order of the registered
holder of such Rights Certificate, registered in such name or names as may be
designated by such holder and (iv) when appropriate, after receipt thereof,
deliver such cash to or upon the order of the registered holder of such Rights
Certificate. The payment of the Exercise Price (as such amount may be reduced
(including to zero) pursuant to Section 11(a)(iii) hereof) and an amount equal
to any applicable transfer tax required to be paid by the holder of such Rights
Certificate in accordance with Section 9(e) hereof, may be made in cash or by
certified bank check, cashier's check or bank draft payable to the order of the
Company. In the event that the Company is obligated to issue securities of the
Company other than Preferred Shares, pay

                                      -11-
<PAGE>   15
cash and/or distribute other property pursuant to Section 11(a) hereof, the
Company will make all arrangements necessary so that such other securities, cash
and/or other property are available for distribution by the Rights Agent, if and
when appropriate.

                    (d) In case the registered holder of any Rights Certificate
shall exercise less than all the Rights evidenced thereby, a new Rights
Certificate evidencing Rights equivalent to the Rights remaining unexercised
shall be issued by the Rights Agent to the registered holder of such Rights
Certificate or to his or her duly authorized assigns, subject to the provisions
of Section 14 hereof.

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

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

         Section 8. Cancellation and Destruction of Rights Certificates. All
Rights Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or to any of its
agents, be delivered to the Rights Agent for cancellation or in canceled form,
or, if surrendered to the Rights Agent, shall be canceled by it, and no Rights
Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this Agreement. The Company shall deliver to the Rights
Agent for cancellation and retirement, and the Rights Agent shall so

                                      -12-
<PAGE>   16
cancel and retire, any Rights Certificate purchased or acquired by the Company
otherwise than upon the exercise thereof. The Rights Agent shall deliver all
canceled Rights Certificates to the Company, or shall, at the written request of
the Company, destroy such canceled Rights Certificates, and in such case shall
deliver a certificate of destruction thereof to the Company.

         Section 9.   Reservation and Availability of Preferred Shares.

                  (a) The Company covenants and agrees that it will use its best
efforts to cause to be reserved and kept available out of its authorized and
unissued Preferred Shares not reserved for another purpose (and, following the
occurrence of a Triggering Event, out of its authorized and unissued Common
Shares and/or other securities), the number of Preferred Shares (and, following
the occurrence of the Triggering Event, Common Shares and/or other securities)
that will be sufficient to permit the exercise in full of all outstanding
Rights.

                  (b) If the Company shall hereafter list any of its Preferred
Shares on a national securities exchange, then so long as the Preferred Shares
(and, following the occurrence of a Triggering Event, Common Shares and/or
other securities) issuable and deliverable upon exercise of the Rights may be
listed on such exchange, the Company shall use its best efforts to cause, from
and after such time as the Rights become exercisable (but only to the extent
that it is reasonably likely that the Rights will be exercised), all shares
reserved for such issuance to be listed on such exchange upon official notice of
issuance upon such exercise.

                  (c) The Company shall use its best efforts to (i) file, as
soon as practicable following the earliest date after the first occurrence of a
Triggering Event in which the consideration to be delivered by the Company upon
exercise of the Rights is described in Section 11(a)(ii) or Section 11(a)(iii)
hereof, or as soon as is required by law following the Distribution Date, as the
case may be, a registration statement under the Securities Act with respect to
the securities purchasable upon exercise of the Rights on an appropriate form,
(ii) cause such registration statement to become effective as soon as
practicable after such filing and (iii) cause such registration statement to
remain effective (with a prospectus at all times meeting the requirements of the
Securities Act) until the earlier of (A) the date as of which the Rights are no
longer exercisable for such securities and (B) the date of expiration of the
Rights. The Company may temporarily suspend, for a period not to exceed ninety
(90) days after the date set forth in clause (i) of the first sentence of this
Section 9(c), the exercisability of the Rights in order to prepare and file such
registration statement and permit it to become effective. Upon any such
suspension, the Company shall issue a public announcement stating, and notify
the Rights Agent, that the exercisability of the Rights has been temporarily
suspended, as well as a public announcement and notification to the Rights Agent
at such time as the suspension is no longer in effect. 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, or an
exemption therefrom shall be available, and until a registration statement has
been declared effective.

                                      -13-
<PAGE>   17
                  (d) The Company covenants and agrees that it will take all
such action as may be necessary to ensure that all Preferred Shares (or other
securities of the Company) delivered upon exercise of Rights shall, at the time
of delivery of the certificates for such securities (subject to payment of the
Exercise Price), be duly and validly authorized and issued and fully paid and
nonassessable shares.

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

         Section 10. Record Date. Each Person in whose name any certificate for
a number of one-thousandths of a Preferred Share (or other securities of the
Company) is issued upon the exercise of Rights shall for all purposes be deemed
to have become the holder of record of Preferred Shares (or other securities of
the Company) represented thereby on, and such certificate shall be dated, the
date upon which the Rights Certificate evidencing such Rights was duly
surrendered and payment of the Total Exercise Price with respect to which the
Rights have been exercised (and any applicable transfer taxes) was made;
provided, however, that if the date of such surrender and payment is a date upon
which the 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, the next succeeding Business Day on which the transfer books of the
Company are open. Prior to the exercise of the Rights evidenced thereby, the
holder of a Rights Certificate shall not be entitled to any rights of a holder
of Preferred Shares (or other securities of the Company) for which the Rights
shall be exercisable, including, without limitation, the right to vote, to
receive dividends or other distributions or to exercise any preemptive rights,
and shall not be entitled to receive any notice of any proceedings of the
Company, except as provided herein.

         Section 11. Adjustment of Exercise Price, Number of Shares or Number of
Rights. The Exercise Price, the number and kind of shares or other property
covered by each Right and the number of Rights outstanding are subject to
adjustment from time to time as provided in this Section 11.

                  (a) (i) Anything in this Agreement to the contrary
notwithstanding, in the event the Company shall at any time after the date of
this Agreement (A) declare a dividend on the Preferred Shares payable in
Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine
the outstanding Preferred Shares (by reverse stock split or otherwise) into a
smaller number of Preferred Shares, or (D) issue any shares of its capital stock
in a reclassification of the Preferred Shares (including any such
reclassification in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation), then, in each such event,
except as otherwise provided in this Section 11 and Section 7(e) hereof: (1) the
Exercise Price in effect at the time of the record date for such

                                      -14-
<PAGE>   18
dividend or of the effective date of such subdivision, combination or
reclassification shall be adjusted so that the Exercise Price thereafter shall
equal the result obtained by dividing the Exercise Price in effect immediately
prior to such time by a fraction (the "Adjustment Fraction"), the numerator of
which shall be the total number of Preferred Shares (or shares of capital stock
issued in such reclassification of the Preferred Shares) outstanding immediately
following such time and the denominator of which shall be the total number of
Preferred Shares outstanding immediately prior to such time; provided, however,
that in no event shall the consideration to be paid upon the exercise of one
Right be less than the aggregate par value of the shares of capital stock of the
Company issuable upon exercise of such Right; and (2) the number of
one-thousandths of a Preferred Share (or share of such other capital stock)
issuable upon the exercise of each Right shall equal the number of
one-thousandths of a Preferred Share (or share of such other capital stock) as
was issuable upon exercise of a Right immediately prior to the occurrence of the
event described in clauses (A)-(D) of this Section 11(a)(i), multiplied by the
Adjustment Fraction; provided, however, that, no such adjustment shall be made
pursuant to this Section 11(a)(i) to the extent that there shall have
simultaneously occurred an event described in clause (A), (B), (C) or (D) of
Section 11(n) with a proportionate adjustment being made thereunder. Each Common
Share that shall become outstanding after an adjustment has been made pursuant
to this Section 11(a)(i) shall have associated with it the number of Rights,
exercisable at the Exercise Price and for the number of one-thousandths of a
Preferred Share (or shares of such other capital stock) as one Common Share has
associated with it immediately following the adjustment made pursuant to this
Section 11(a)(i).

                           (ii)     Subject to Section 24 of this Agreement, in
the event a Triggering Event shall have occurred, then promptly following such
Triggering Event each holder of a Right, except as provided in Section 7(e)
hereof, shall thereafter have the right to receive for each Right, upon exercise
thereof in accordance with the terms of this Agreement and payment of the
Exercise Price in effect immediately prior to the occurrence of the Triggering
Event, in lieu of a number of one-thousandths of a Preferred Share, such number
of Common Shares of the Company as shall equal the result obtained by
multiplying the Exercise Price in effect immediately prior to the occurrence of
the Triggering Event by the number of one-thousandths of a Preferred Share for
which a Right was exercisable (or would have been exercisable if the
Distribution Date had occurred) immediately prior to the first occurrence of a
Triggering Event, and dividing that product by 50% of the Current Per Share
Market Price for Common Shares on the date of occurrence of the Triggering
Event; provided, however, that the Exercise Price and the number of Common
Shares of the Company so receivable upon exercise of a Right shall be subject to
further adjustment as appropriate in accordance with Section 11(e) hereof to
reflect any events occurring in respect of the Common Shares of the Company
after the occurrence of the Triggering Event.

                            (iii)    In lieu of issuing Common Shares in
accordance with Section 11(a)(ii) hereof, the Company may, if the Company's
Board of Directors determines that such action is necessary or appropriate and
not contrary to the interest of holders of Rights and, in the event that the
number of Common Shares which are authorized by the Company's Restated
Certificate of Incorporation but not outstanding or reserved for issuance for
purposes other than upon exercise of the Rights are not sufficient to permit the
exercise in full of the Rights, or if any necessary regulatory approval for such
issuance has not been obtained by the Company, the Company shall: (A) determine
the excess of (1) the value of the Common Shares issuable upon the exercise of a
Right (the "Current Value") over (2) the Exercise Price (such excess, the
"Spread") and (B) with respect to each Right, make adequate provision to
substitute for such

                                      -15-
<PAGE>   19
Common Shares, upon exercise of the Rights, (1) cash, (2) a
reduction in the Exercise Price, (3) other equity securities of the Company
(including, without limitation, shares or units of shares of any series of
preferred stock which the Company's Board of Directors has deemed to have the
same value as Common Shares (such shares or units of shares of preferred stock
are herein called "Common Stock Equivalents")), except to the extent that the
Company has not obtained any necessary stockholder or regulatory approval for
such issuance, (4) debt securities of the Company, except to the extent that the
Company has not obtained any necessary stockholder or regulatory approval for
such issuance, (5) other assets or (6) any combination of the foregoing, having
an aggregate value equal to the Current Value, where such aggregate value has
been determined by the Company's Board of Directors based upon the advice of a
nationally recognized investment banking firm selected by the Company's Board of
Directors; provided, however, if the Company shall not have made adequate
provision to deliver value pursuant to clause (B) above within thirty (30) days
following the later of (x) the first occurrence of a Triggering Event and (y)
the date on which the Company's right of redemption pursuant to Section 23(a)
expires (the later of (x) and (y) being referred to herein as the "Section
11(a)(ii) Trigger Date"), then the Company shall be obligated to deliver, upon
the surrender for exercise of a Right and without requiring payment of the
Exercise Price, Common Shares (to the extent available), except to the extent
that the Company has not obtained any necessary stockholder or regulatory
approval for such issuance, and then, if necessary, cash, which shares and/or
cash have an aggregate value equal to the Spread. If the Company's Board of
Directors shall determine in good faith that it is likely that sufficient
additional Common Shares could be authorized for issuance upon exercise in full
of the Rights or that any necessary regulatory approval for such issuance will
be obtained, the thirty (30) day period set forth above may be extended to the
extent necessary, but not more than ninety (90) days after the Section 11(a)(ii)
Trigger Date, in order that the Company may seek stockholder approval for the
authorization of such additional shares or take action to obtain such regulatory
approval (such period, as it may be extended, the "Substitution Period"). To the
extent that the Company determines that some action need be taken pursuant to
the first and/or second sentences of this Section 11(a)(iii), the Company (x)
shall provide, subject to Section 7(e) hereof, that such action shall apply
uniformly to all outstanding Rights and (y) may suspend the exercisability of
the Rights until the expiration of the Substitution Period in order to seek any
authorization of additional shares, to take any action to obtain any required
regulatory approval and/or to decide the appropriate form of distribution to be
made pursuant to such first sentence and to determine the value thereof. In the
event of any such suspension, the Company shall issue a public announcement
stating that the exercisability of the Rights has been temporarily suspended, as
well as a public announcement at such time as the suspension is no longer in
effect. For purposes of this Section 11(a)(iii), the value of the Common Shares
shall be the Current Per Share Market Price of the Common Shares on the Section
11(a)(ii) Trigger Date and the value of any Common Stock Equivalent shall be
deemed to have the same value as the Common Shares on such date.

                (b)     In case the Company shall, at any time after the date of
this Agreement, fix a record date for the issuance of rights, options or
warrants to all holders of Preferred Shares entitling such holders (for a period
expiring within forty-five (45) calendar days after such record date) to
subscribe for or purchase Preferred Shares or Equivalent Shares or securities
convertible into Preferred Shares or Equivalent Shares at a price per share (or
having a conversion price per share, if a security convertible into Preferred
Shares or Equivalent Shares) less than the then Current Per Share Market Price
of the Preferred Shares or Equivalent Shares on such record date, then, in each
such case, the Exercise Price

                                      -16-
<PAGE>   20
to be in effect after such record date shall be determined by multiplying the
Exercise Price in effect immediately prior to such record date by a fraction,
the numerator of which shall be the number of Preferred Shares and Equivalent
Shares (if any) outstanding on such record date, plus the number of Preferred
Shares or Equivalent Shares, as the case may be, which the aggregate offering
price of the total number of Preferred Shares or Equivalent Shares, as the case
may be, to be offered or issued (and/or the aggregate initial conversion price
of the convertible securities to be offered or issued) would purchase at such
current market price, and the denominator of which shall be the number of
Preferred Shares and Equivalent Shares (if any) outstanding on such record date,
plus the number of additional Preferred Shares or Equivalent Shares, as the case
may be, to be offered for subscription or purchase (or into which the
convertible securities so to be offered are initially convertible); provided,
however, that in no event shall the consideration to be paid upon the exercise
of one Right be less than the aggregate par value of the shares of capital stock
of the Company issuable upon exercise of one Right. In case such subscription
price may be paid in a consideration part or all of which shall be in a form
other than cash, the value of such consideration shall be as determined in good
faith by the Company's Board of Directors, whose determination shall be
described in a statement filed with the Rights Agent and shall be binding on the
Rights Agent and the holders of the Rights. Preferred Shares and Equivalent
Shares owned by or held for the account of the Company shall not be deemed
outstanding for the purpose of any such computation. Such adjustment shall be
made successively whenever such a record date is fixed, and in the event that
such rights, options or warrants are not so issued, the Exercise Price shall be
adjusted to be the Exercise Price which would then be in effect if such record
date had not been fixed.

                (c)     In case the Company shall, at any time after the date of
this Agreement, fix a record date for the making of a distribution to all
holders of the Preferred Shares or of any class or series of Equivalent Shares
(including any such distribution made in connection with a consolidation or
merger in which the Company is the continuing or surviving corporation) of
evidences of indebtedness or assets (other than a regular quarterly cash
dividend, if any, or a dividend payable in Preferred Shares) or subscription
rights, options or warrants (excluding those referred to in Section 11(b)),
then, in each such case, the Exercise Price to be in effect after such record
date shall be determined by multiplying the Exercise Price in effect immediately
prior to such record date by a fraction, the numerator of which shall be the
Current Per Share Market Price of a Preferred Share or an Equivalent Share on
such record date, less the fair market value per Preferred Share or Equivalent
Share (as determined in good faith by the Board of Directors of the Company,
whose determination shall be described in a statement filed with the Rights
Agent) of the portion of the cash, assets or evidences of indebtedness so to be
distributed or of such subscription rights or warrants applicable to a Preferred
Share or Equivalent Share, as the case may be, and the denominator of which
shall be such Current Per Share Market Price of a Preferred Share or Equivalent
Share on such record date; provided, however, that in no event shall the
consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right. Such adjustments shall be made successively whenever such
a record date is fixed, and in the event that such distribution is not so made,
the Exercise Price shall be adjusted to be the Exercise Price which would have
been in effect if such record date had not been fixed.

                (d)     Anything herein to the contrary notwithstanding, no
adjustment in the Exercise Price shall be required unless such adjustment would
require an increase or decrease of at least 1% in the

                                      -17-
<PAGE>   21
Exercise Price; provided, however, that any adjustments which by reason of this
Section 11(d) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment. All calculations under this Section
11 shall be made to the nearest cent or to the nearest ten-thousandth of a
Common Share or other share or one hundred-thousandth of a Preferred Share, as
the case may be. Notwithstanding the first sentence of this Section 11(d), any
adjustment required by this Section 11 shall be made no later than the earlier
of (i) three (3) years from the date of the transaction which requires such
adjustment or (ii) the Expiration Date.

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

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

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

                (h)     The Company may elect on or after the date of any
adjustment of the Exercise Price as a result of the calculations made in Section
11(b) or (c) to adjust the number of Rights, in substitution for any adjustment
in the number of Preferred Shares purchasable upon the exercise of a Right. Each
of the Rights outstanding after such adjustment of the number of Rights shall be
exercisable for the number of one-thousandths of a Preferred Share for which a
Right was exercisable immediately prior to such adjustment. Each Right held of
record prior to such adjustment of the number of Rights shall become that number
of Rights (calculated to the nearest one hundred-thousandth) obtained by
dividing the Exercise Price in effect immediately prior to adjustment of the
Exercise Price by the Exercise Price in effect immediately after adjustment of
the Exercise Price. The Company shall make a public announcement of its election
to adjust the number of Rights, indicating the record date for the adjustment,
and, if known at the time, the amount of the adjustment to be made. This record
date may be the date on which the Exercise Price is adjusted or any day
thereafter, but, if the Rights Certificates have been issued, shall be at least
ten (10) days later than the date of the public announcement. If Rights
Certificates

                                      -18-
<PAGE>   22
have been issued, upon each adjustment of the number of Rights pursuant to this
Section 11(h), the Company shall, as promptly as practicable, cause to be
distributed to holders of record of Rights Certificates on such record date
Rights Certificates evidencing, subject to Section 14 hereof, the additional
Rights to which such holders shall be entitled as a result of such adjustment,
or, at the option of the Company, shall cause to be distributed to such holders
of record in substitution and replacement for the Rights Certificates held by
such holders prior to the date of adjustment, and upon surrender thereof, if
required by the Company, new Rights Certificates evidencing all the Rights to
which such holders shall be entitled after such adjustment. Rights Certificates
so to be distributed shall be issued, executed and countersigned in the manner
provided for herein (and may bear, at the option of the Company, the adjusted
Exercise Price) and shall be registered in the names of the holders of record of
Rights Certificates on the record date specified in the public announcement.

                (i)     Irrespective of any adjustment or change in the Exercise
Price or the number of Preferred Shares issuable upon the exercise of the
Rights, the Rights Certificates theretofore and thereafter issued may continue
to express the Exercise Price per one one-thousandth of a Preferred Share and
the number of one-thousandths of a Preferred Share which were expressed in the
initial Rights Certificates issued hereunder.

                (j)     Before taking any action that would cause an adjustment
reducing the Exercise Price below the par or stated value, if any, of the number
of one-thousandths of a Preferred Share issuable upon exercise of the Rights,
the Company shall take any corporate action which may, in the opinion of its
counsel, be necessary in order that the Company may validly and legally issue as
fully paid and nonassessable shares such number of one-thousandths of a
Preferred Share at such adjusted Exercise Price.

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

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

<PAGE>   23
                (m)     The Company covenants and agrees that, after the
Distribution Date, it will not, except as permitted by Sections 23, 24 or 27
hereof, take (or permit to be taken) any action if at the time such action is
taken it is reasonably foreseeable that such action will diminish substantially
or otherwise eliminate the benefits intended to be afforded by the Rights.

                (n)     In the event the Company shall at any time after the
date of this Agreement (A) declare a dividend on the Common Shares payable in
Common Shares, (B) subdivide the outstanding Common Shares, (C) combine the
outstanding Common Shares (by reverse stock split or otherwise) into a smaller
number of Common Shares, or (D) issue any shares of its capital stock in a
reclassification of the Common Shares (including any such reclassification in
connection with a consolidation or merger in which the Company is the continuing
or surviving corporation), then, in each such event, except as otherwise
provided in this Section 11(a) and Section 7(e) hereof: (1) each Common Share
(or shares of capital stock issued in such reclassification of the Common
Shares) outstanding immediately following such time shall have associated with
it the number of Rights as were associated with one Common Share immediately
prior to the occurrence of the event described in clauses (A)-(D) above; (2) the
Exercise Price in effect at the time of the record date for such dividend or of
the effective date of such subdivision, combination or reclassification shall be
adjusted so that the Exercise Price thereafter shall equal the result obtained
by multiplying the Exercise Price in effect immediately prior to such time by a
fraction, the numerator of which shall be the total number of Common Shares
outstanding immediately prior to the event described in clauses (A)-(D) above,
and the denominator of which shall be the total number of Common Shares
outstanding immediately after such event; provided, however, that in no event
shall the consideration to be paid upon the exercise of one Right be less than
the aggregate par value of the shares of capital stock of the Company issuable
upon exercise of such Right; and (3) the number of one-thousandths of a
Preferred Share (or shares of such other capital stock) issuable upon the
exercise of each Right outstanding after such event shall equal the number of
one-thousandths of a Preferred Share (or shares of such other capital stock) as
were issuable with respect to one Right immediately prior to such event. Each
Common Share that shall become outstanding after an adjustment has been made
pursuant to this Section 11(n) shall have associated with it the number of
Rights, exercisable at the Exercise Price and for the number of one-thousandths
of a Preferred Share (or shares of such other capital stock) as one Common Share
has associated with it immediately following the adjustment made pursuant to
this Section 11(n). If an event occurs which would require an adjustment under
both this Section 11(n) and Section 11(a)(ii) hereof, the adjustment provided
for in this Section 11(n) shall be in addition to, and shall be made prior to,
any adjustment required pursuant to Section 11(a)(ii) hereof.

        Section 12.     Certificate of Adjusted Exercise Price or Number of
Shares. Whenever an adjustment is made as provided in Sections 11 and 13 hereof,
the Company shall promptly (a) prepare a certificate setting forth such
adjustment and a brief statement of the facts accounting for such adjustment,
(b) file with the Rights Agent and with each transfer agent for the Preferred
Shares a copy of such certificate and (c) mail a brief summary thereof to each
holder of a Rights Certificate in accordance with Section 26 hereof.
Notwithstanding the foregoing sentence, the failure of the Company to make such
certification or give such notice shall not affect the validity of such
adjustment or the force or effect of the requirement for such adjustment. The
Rights Agent shall be fully protected in relying on any such certificate and on
any adjustment contained therein and shall not be deemed to have knowledge of
such 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, following a Triggering Event,
directly or indirectly:

                           (i)      the Company shall consolidate with, or merge
with and into, any other Person (other than a wholly-owned Subsidiary of the
Company in a transaction the principal purpose of which is to change the state
of incorporation of the Company and which complies with Section 11(m) hereof);

                           (ii)     any Person shall consolidate with the
Company, 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 merger, all or part of the Common Shares shall be changed
into or exchanged for stock or other securities of any other person (or the
Company); or

                           (iii)    the Company shall sell or otherwise transfer
(or one or more of its Subsidiaries shall sell or otherwise transfer), in one or
more transactions, assets or earning power aggregating 50% or more of the assets
or earning power of the Company and its Subsidiaries (taken as a whole) to any
other Person or Persons (other than the Company or one or more of its wholly
owned Subsidiaries in one or more transactions, each of which individually (and
together) complies with Section 11(m) hereof),

                                    then, concurrent with and in each such case,

                                    (A)     each holder of a Right (except as
provided in Section 7(e) hereof) shall thereafter have the right to receive,
upon the exercise thereof at a price equal to the Total Exercise Price
applicable immediately prior to the occurrence of the Section 13 Event in
accordance with the terms of this Agreement, such number of validly authorized
and issued, fully paid, nonassessable and freely tradeable Common Shares of the
Principal Party (as hereinafter defined), free of any liens, encumbrances,
rights of first refusal or other adverse claims, as shall be equal to the result
obtained by dividing such Total Exercise Price by 50% of the Current Per Share
Market Price of the Common Shares of such Principal Party on the date of
consummation of such Section 13 Event, provided, however, that the Exercise
Price and the number of Common Shares of such Principal Party so receivable upon
exercise of a Right shall be subject to further adjustment as appropriate in
accordance with Section 11(e) hereof;

                                    (B)     such Principal Party shall
thereafter be liable for, and shall assume, by virtue of such Section 13 Event,
all the obligations and duties of the Company pursuant to this Agreement;

                                    (C)     the term "Company" shall thereafter
be deemed to refer to such Principal Party, it being specifically intended that
the provisions of Section 11 hereof shall apply only to such Principal Party
following the first occurrence of a Section 13 Event;

                                    (D)     such Principal Party shall take such
steps (including, but not limited to, the reservation of a sufficient number of
its Common Shares) in connection with the consummation

                                      -21-
<PAGE>   25
of any such transaction as may be necessary to ensure that the provisions hereof
shall thereafter be applicable, as nearly as reasonably may be, in relation to
its Common Shares thereafter deliverable upon the exercise of the Rights; and

                                    (E)     upon the subsequent occurrence of
any consolidation, merger, sale or transfer of assets or other extraordinary
transaction in 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
Total Exercise Price as provided in this Section 13(a), such cash, shares,
rights, warrants and other property which such holder would have been entitled
to receive had such holder, at the time of such transaction, owned the Common
Shares of the Principal Party receivable upon the exercise of such Right
pursuant to this Section 13(a), 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.

                                    (F)     For purposes hereof, the "earning
power" of the Company and its Subsidiaries shall be determined in good faith by
the Company's Board of Directors on the basis of the operating earnings of each
business operated by the Company and its Subsidiaries during the three fiscal
years preceding the date of such determination (or, in the case of any business
not operated by the Company or any Subsidiary during three full fiscal years
preceding such date, during the period such business was operated by the Company
or any Subsidiary).

                  (b)      For purposes of this Agreement, the term "Principal
Party" shall mean:

                           (i)      in the case of any transaction described in
clause (i) or (ii) of Section 13(a) hereof: (A) the Person that is the issuer of
the securities into which the Common Shares are converted in such merger or
consolidation, or, if there is more than one such issuer, the issuer the Common
Shares of which have the greatest aggregate market value of shares outstanding,
or (B) if no securities are so issued, (x) the Person that is the other party to
the merger, if such Person survives said merger, or, if there is more than one
such Person, the Person the Common Shares of which have the greatest aggregate
market value of shares outstanding or (y) if the Person that is the other party
to the merger does not survive the merger, the Person that does survive the
merger (including the Company if it survives) or (z) the Person resulting from
the consolidation; and

                           (ii)     in the case of any transaction described in
clause (iii) of Section 13(a) hereof, 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 more than one Person that is a party to such
transaction or transactions receives the same portion of the assets or earning
power so transferred and each such portion would, were it not for the other
equal portions, constitute the greatest 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 is the issuer of
Common Shares having the greatest aggregate market value of shares outstanding;
provided, however, that in any such case described in the foregoing clause
(b)(i) or (b)(ii), if the Common Shares of such Person are not at such time or
have not been continuously over the preceding 12-month period registered under
Section 12 of the Exchange Act, then (1) if such Person is a direct or indirect
Subsidiary of another Person the

                                      -22-
<PAGE>   26
Common Shares of which are and have been so registered, the term "Principal
Party" shall refer to such other Person, or (2) if such Person is a Subsidiary,
directly or indirectly, of more than one Person, the Common Shares of which are
and have been so registered, the term "Principal Party" shall refer to whichever
of such Persons is the issuer of Common Shares having the greatest aggregate
market value of shares outstanding, or (3) if such Person is owned, directly or
indirectly, by a joint venture formed by two or more Persons that are not owned,
directly or indirectly by the same Person, the rules set forth in clauses (1)
and (2) above shall apply to each of the owners having an interest in the
venture as if the Person owned by the joint venture was a Subsidiary of both or
all of such joint venturers, and the Principal Party in each such case shall
bear the obligations set forth in this Section 13 in the same ratio as its
interest in such Person bears to the total of such interests.

                (c)     The Company shall not consummate any Section 13 Event
unless the Principal Party shall have a sufficient number of authorized Common
Shares that have not been issued or reserved for issuance to permit the exercise
in full of the Rights in accordance with this Section 13 and unless prior
thereto the Company and such issuer shall have executed and delivered to the
Rights Agent a supplemental agreement confirming that such Principal Party
shall, upon consummation of such Section 13 Event, assume this Agreement in
accordance with Sections 13(a) and 13(b) hereof, that all rights of first
refusal or preemptive rights in respect of the issuance of Common Shares of such
Principal Party upon exercise of outstanding Rights have been waived, that there
are no rights, warrants, instruments or securities outstanding or any agreements
or arrangements which, as a result of the consummation of such transaction,
would eliminate or substantially diminish the benefits intended to be afforded
by the Rights and that such transaction shall not result in a default by such
Principal Party under this Agreement, and further providing that, as soon as
practicable after the date of such Section 13 Event, such Principal Party will:

                           (i)      prepare and file a registration statement
under the Securities 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 Securities Act) until the Expiration Date, 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 purchasable upon exercise of the
Rights on a national securities exchange or to meet the eligibility requirements
for quotation on Nasdaq and list (or continue the listing of) the Rights and the
securities purchasable upon exercise of the Rights on Nasdaq; and

                           (iii)    deliver to holders of the Rights historical
financial statements for such 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 at any time after the occurrence of a Triggering
Event some or all of the Rights shall not have been exercised at the time of a
transaction described in this Section 13, the Rights which

                                      -23-
<PAGE>   27
have not theretofore been exercised shall thereafter be exercisable in the
manner described in Section 13(a) (without taking into account any prior
adjustment required by Section 11(a)(ii)).

                  (d) In case the "Principal Party" for purposes of Section
13(b) hereof has 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 (other than to holders of Rights pursuant to Section 13
hereof), in connection with, or as a consequence of, the consummation of a
Section 13 Event, Common Shares or Equivalent Shares of such Principal Party at
less than the then Current Per Share Market Price thereof or securities
exercisable for, or convertible into, Common Shares or Equivalent Shares of such
Principal Party at less than such then Current Per Share Market Price, or (ii)
providing for any special payment, tax or similar provision in connection with
the issuance of the Common Shares of such Principal Party pursuant to the
provisions of Section 13 hereof, then, in such event, the Company hereby agrees
with each holder of Rights that it 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 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.

                  (e) The Company covenants and agrees that it shall not, at any
time after the Distribution Date, effect or permit to occur any Section 13
Event, if (i) at the time or immediately after such Section 13 Event there are
any rights, warrants or other instruments or securities outstanding or
agreements in effect which would substantially diminish or otherwise eliminate
the benefits intended to be afforded by the Rights, (ii) prior to,
simultaneously with or immediately after such Section 13 Event, the stockholders
of the Person who constitutes, or would constitute, the "Principal Party" for
purposes of Section 13(b) hereof shall have received a distribution of Rights
previously owned by such Person or any of its Affiliates or Associates or (iii)
the form or nature of organization of the Principal Party would preclude or
limit the exercisability of the Rights.

                  (f) The provisions of this Section 13 shall similarly apply to
successive mergers or consolidations or sales or other transfers.

         Section 14.  Fractional Rights and Fractional Shares.

                  (a) The Company shall not be required to issue fractions of
Rights or to distribute Rights Certificates which evidence fractional Rights. In
lieu of such fractional Rights, there shall be paid to the registered holders of
the Rights Certificates with regard to which such fractional Rights would
otherwise be issuable, an amount in cash equal to the same fraction of the
current market value of a whole Right. For the purposes of this Section 14(a),
the current market value of a whole Right shall be the closing price of the
Rights for the Trading Day immediately prior to the date on which such
fractional Rights would have been otherwise issuable, as determined pursuant to
the second sentence of Section 1(j) hereof.

                                      -24-
<PAGE>   28
                  (b) The Company shall not be required to issue fractions of
Preferred Shares (other than fractions that are integral multiples of one
one-thousandth of a Preferred Share) upon exercise of the Rights or to
distribute certificates which evidence fractional Preferred Shares (other than
fractions that are integral multiples of one one-thousandth of a Preferred
Share). Interests in fractions of Preferred Shares in integral multiples of one
one-thousandth of a Preferred Share may, at the election of the Company, be
evidenced by depositary receipts, 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 the rights,
privileges and preferences to which they are entitled as beneficial owners of
the Preferred Shares represented by such depositary receipts. In lieu of
fractional Preferred Shares that are not integral multiples of one
one-thousandth of a Preferred Share, the Company shall pay to the registered
holders of Rights Certificates at the time such Rights are exercised as herein
provided an amount in cash equal to the same fraction of the current market
value of a Preferred Share. For purposes of this Section 14(b), the current
market value of a Preferred Share shall be one thousand times the closing price
of a Common Share (as determined pursuant to the second sentence of Section 1(j)
hereof) for the Trading Day immediately prior to the date of such exercise.

                  (c) The Company shall not be required to issue fractions of
Common Shares or to distribute certificates which evidence fractional Common
Shares upon the exercise or exchange of Rights. In lieu of such fractional
Common Shares, the Company shall pay to the registered holders of Rights
Certificates at the time such Rights are exercised as herein provided an amount
in cash equal to the same fraction of the current market value of a Common
Share. For purposes of this Section 14(c), the current market value of a Common
Share shall be the closing price of a Common Share (as determined pursuant to
the second sentence of Section 1(j) hereof) for the Trading Day immediately
prior to the date of such exercise.

                  (d) The holder of a Right by the acceptance of the Right
expressly waives his or her right to receive any fractional Rights or any
fractional shares (other than fractions that are integral multiples of one
one-thousandth of a Preferred Share) upon exercise of a Right.

         Section 15. Rights of Action. All rights of action in respect of this
Agreement, excepting the rights of action given to the Rights Agent under
Section 18 hereof, are vested in the respective registered holders of the Rights
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Shares); and any registered holder of any Rights Certificate (or, prior
to the Distribution Date, of the Common Shares), without the consent of the
Rights Agent or of the holder of any other Rights Certificate (or, prior to the
Distribution Date, of the Common Shares), may, in his or her own behalf and for
his or her 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 or her right to exercise the Rights evidenced by such Rights Certificate in
the manner provided in such Rights Certificate and in this Agreement. Without
limiting the foregoing or any remedies available to the holders of Rights, it is
specifically acknowledged that the holders of Rights would not have an adequate
remedy at law for any breach of this Agreement and will be entitled to specific
performance of the obligations under, and injunctive relief against actual or
threatened violations of, the obligations of any Person subject to this
Agreement.

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

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

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

                  (c)    subject to Sections 6(a) and 7(f) hereof, the Company
and the Rights Agent may deem and treat the person in whose name the Rights
Certificate (or, prior to the Distribution Date, the associated Common Shares
certificate) is registered as the absolute owner thereof and of the Rights
evidenced thereby (notwithstanding any notations of ownership or writing on the
Rights Certificates or the associated Common Shares 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.     Rights Certificate Holder Not Deemed a Stockholder. No
holder, as such, of any Rights Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose to be the holder of the Preferred Shares
or any other securities of the Company which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall anything contained herein
or in any Rights Certificate be construed to confer upon the holder of any
Rights Certificate, as such, any of the rights of a stockholder of the Company
or any right to vote for the election of directors or upon any matter submitted
to stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 25 hereof), or to receive dividends
or subscription rights, or otherwise, until the Right or Rights evidenced by
such Rights Certificate shall have been exercised in accordance with the
provisions hereof.

         Section 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
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
by the Rights Agent in connection with the acceptance and administration of this
Agreement, including the costs and expenses of defending against any claim of
liability in the premises. In no event will the Rights Agent be liable for
special, indirect, incidental or consequential loss or damage of any kind
whatsoever, even if the Rights Agent has been advised of the possibility of such
loss or damage.

<PAGE>   30
                  (b) The Rights Agent shall be protected and shall incur no
liability for, or in respect of any action taken, suffered or omitted by it in
connection with, its administration of this Agreement in reliance upon any
Rights Certificate or certificate for the Preferred Shares or Common Shares 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 reasonably believed by it to
be genuine and to be signed, executed and, where necessary, verified or
acknowledged, by the proper Person or Persons, or otherwise upon the advice of
counsel as set forth in Section 20 hereof.

         Section 19.  Merger or Consolidation or Change of Name of Rights Agent.

                  (a) Any corporation into which the Rights Agent or any
successor Rights Agent may be merged or with which it may be consolidated, or
any corporation resulting from any merger or consolidation to which the Rights
Agent or any successor Rights Agent shall be a party, or any corporation
succeeding to the corporate trust business of the Rights Agent or any successor
Rights Agent, shall be the successor to the Rights Agent under this Agreement
without the execution or filing of any paper or any further act on the part of
any of the parties hereto; provided, however, that such corporation would be
eligible for appointment as a successor Rights Agent under the provisions of
Section 21 hereof. In case at the time such successor Rights Agent shall succeed
to the agency created by this Agreement, any of the Rights Certificates shall
have been countersigned but not delivered, any such successor Rights Agent may
adopt the countersignature of the predecessor Rights Agent and deliver such
Rights Certificates so countersigned; and in case at that time any of the Rights
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Rights Certificates either in the name of the predecessor
Rights Agent or in the name of the successor Rights Agent; and in all such cases
such Rights Certificates shall have the full force provided in the Rights
Certificates and in this Agreement.

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

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

                  (a) The Rights Agent may consult with legal counsel (who may
be legal counsel for the Company), and the written advice or 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 written advice or opinion.

                  (b) Whenever in the performance of its duties under this
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter (including, without limitation, the identity of

                                      -27-
<PAGE>   31
any Acquiring Person and the determination of Current Per Share Market Price) be
proved or established by the Company prior to taking or suffering any action
hereunder, such fact or matter (unless other evidence in respect thereof be
herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by any one of the Chairman of the Board, the
Chief Executive Officer, the President, any Vice President, the Chief Financial
Officer, the Secretary or any Assistant Secretary of the Company and delivered
to the Rights Agent; and 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 Agreement in reliance upon such certificate.

                  (c) The Rights Agent shall be liable hereunder to the Company
and any other Person 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 Agreement or in the
Rights 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 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 Rights Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any
covenant or condition contained in this Agreement or in any Rights Certificate;
nor shall it be responsible for any change in the exercisability of the Rights
or any adjustment in the terms of the Rights (including the manner, method or
amount thereof) provided for in Sections 3, 11, 13, 23 or 24, or the
ascertaining of the existence of facts that would require any such change or
adjustment (except with respect to the exercise of Rights evidenced by Rights
Certificates after receipt by the Rights Agent of a certificate furnished
pursuant to Section 12 describing such change or adjustment); nor shall it by
any act hereunder be deemed to make any representation or warranty as to the
authorization or reservation of any Preferred Shares to be issued pursuant to
this Agreement or any Rights Certificate or as to whether any Preferred Shares
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 this Agreement.

                  (g) The Rights Agent is hereby authorized and directed to
accept instructions with respect to the performance of its duties hereunder from
any one of the Chairman of the Board, the Chief Executive Officer, the
President, any Vice President, the Chief Financial Officer, the Secretary or any
Assistant Secretary 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 by it in good faith in accordance with instructions of
any such officer or for any delay in acting while waiting for those
instructions. Any application by the Rights Agent for written instructions from
the Company may, at the option of the Rights Agent, set forth in writing any
action proposed to be taken or omitted by the Rights Agent under

                                      -28-
<PAGE>   32
this Rights Agreement and the date on and/or after which such action shall be
taken or such omission shall be effective. The Rights Agent shall not be liable
for any action taken by, or omission of, the Rights Agent in accordance with a
proposal included in any such application on or after the date specified in such
application (which date shall not be less than five (5) Business Days after the
date any officer of the Company actually receives such application, unless any
such officer shall have consented in writing to an earlier date) unless, prior
to taking any such action (or the effective date in the case of an omission),
the Rights Agent shall have received written instructions in response to such
application specifying the action to be taken or omitted.

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

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

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

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

                                      -29-
<PAGE>   33
Rights Agent or by the holder of a Rights Certificate (who shall, with such
notice, submit his or her Rights Certificate for inspection by the Company),
then the registered holder of any Rights Certificate may apply to any court of
competent jurisdiction for the appointment of a new Rights Agent. Any successor
Rights Agent, whether appointed by the Company or by such a court, shall be a
corporation organized and doing business under the laws of the United States or
of any state of the United States, in good standing, which is authorized under
such laws to exercise corporate trust or stockholder services powers and is
subject to supervision or examination by federal or state authority and which
has at the time of its appointment as Rights Agent a combined capital and
surplus of at least $100 million. After appointment, the successor Rights Agent
shall be vested with the same powers, rights, duties and responsibilities as if
it had been originally named as Rights Agent without further act or deed; but
the predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment, the Company shall file notice
thereof in writing with the predecessor Rights Agent and each transfer agent of
the Preferred Shares and the Common Shares, and mail a notice thereof in writing
to the registered holders of the Rights Certificates. Failure to give any notice
provided for in this Section 21, however, or any defect therein, shall not
affect the legality or validity of the resignation or removal of the Rights
Agent or the appointment of the successor Rights Agent, as the case may be.

         Section 22. Issuance of New Rights Certificates. Notwithstanding any of
the provisions of this Agreement or of the Rights to the contrary, the Company
may, at its option, issue new Rights Certificates evidencing Rights in such form
as may be approved by its Board of Directors to reflect any adjustment or change
in the Exercise Price and the number or kind or class of shares or other
securities or property purchasable under the Rights Certificates made in
accordance with the provisions of this Agreement. In addition, in connection
with the issuance or sale of Common Shares following the Distribution Date and
prior to the redemption or expiration of the Rights, the Company (a) shall, with
respect to Common Shares so issued or sold pursuant to the exercise of stock
options or under any employee plan or arrangement or upon the exercise,
conversion or exchange of other securities of the Company outstanding at the
date hereof or upon the exercise, conversion or exchange of securities
hereinafter issued by the Company and (b) may, in any other case, if deemed
necessary or appropriate by the Board of Directors of the Company, issue Rights
Certificates representing the appropriate number of Rights in connection with
such issuance or sale; provided, however, that (i) no such Rights Certificate
shall be issued and this sentence shall be null and void ab initio if, and to
the extent that, such issuance or this sentence would create a significant risk
of or result in material adverse tax consequences to the Company or the Person
to whom such Rights Certificate would be issued or would create a significant
risk of or result in such options' or employee plans' or arrangements' failing
to qualify for otherwise available special tax treatment and (ii) no such Rights
Certificate shall be issued if, and to the extent that, appropriate adjustment
shall otherwise have been made in lieu of the issuance thereof.

         Section 23.  Redemption.

                  (a) The Company may, at its option and with the approval of
the Board of Directors, at any time prior to the Close of Business on the
earlier of (i) the Shares Acquisition Date and (ii) the Final Expiration Date,
redeem all but not less than all the then outstanding Rights at a redemption
price

                                      -30-
<PAGE>   34
of $0.01 per Right, appropriately adjusted to reflect any stock split,
stock dividend or similar transaction occurring after the date hereof (such
redemption price being herein referred to as the "Redemption Price") and the
Company may, at its option, pay the Redemption Price either in Common Shares
(based on the Current Per Share Market Price thereof at the time of redemption)
or cash. Such redemption of the Rights by the Company may be made effective at
such time, on such basis and with such conditions as the Board of Directors in
its sole discretion may establish. The date on which the Board of Directors
elects to make the redemption effective shall be referred to as the "Redemption
Date."

                  (b)      Immediately upon the action of the Board of Directors
of the Company ordering the redemption of the Rights, evidence of which shall
have been filed with the Rights Agent, and without any further action and
without any notice, the right to exercise the Rights will terminate and the only
right thereafter of the holders of Rights shall be to receive the Redemption
Price. The Company shall promptly give public notice of any such redemption;
provided, however, that the failure to give or any defect in, any such notice
shall not affect the validity of such redemption. Within ten (10) days after the
action of the Board of Directors ordering the redemption of the Rights, the
Company shall give notice of such redemption to the Rights Agent and the holders
of the then outstanding Rights by mailing such notice to all such holders at
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 Shares. Any notice which is mailed in the manner herein provided
shall be deemed given, whether or not the holder receives the notice. Each such
notice of redemption will state the method by which the payment of the
Redemption Price will be made. Neither the Company nor any of its Affiliates or
Associates may redeem, acquire or purchase for value any Rights at any time in
any manner other than that specifically set forth in this Section 23 or in
Section 24 hereof, and other than in connection with the purchase of Common
Shares prior to the Distribution Date.

         Section 24.  Exchange.

                  (a) Subject to applicable laws, rules and regulations, and
subject to subsection 24(c) below, the Company may, at its option, by action of
the Board of Directors, at any time after the occurrence of a Triggering Event,
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 Common Shares at an exchange ratio of one Common 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"). Notwithstanding the foregoing,
the Board of Directors shall not be empowered to effect such exchange at any
time after any Person (other than the Company, any Subsidiary of the Company,
any employee benefit plan of the Company or any such Subsidiary, or any entity
holding Common Shares for or pursuant to the terms of any such plan), together
with all Affiliates and Associates of such Person, becomes the Beneficial Owner
of 50% or more of the Common Shares then outstanding.

                  (b) Immediately upon the action of the Board of Directors
ordering the exchange of any Rights pursuant to subsection 24(a) of this Section
24 and without any further action and without any notice, the right to exercise
such Rights shall terminate and the only right thereafter of a holder of such
Rights shall be to receive that number of Common Shares equal to the number of
such Rights held

                                      -31-
<PAGE>   35
by such holder multiplied by the Exchange Ratio. The Company shall give public
notice of any such exchange; provided, however, that the failure to give, or any
defect in, such notice shall not affect the validity of such exchange. The
Company shall mail 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 Common Shares 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.

                  (c) In the event that there shall not be sufficient Common
Shares issued but not outstanding or authorized but unissued to permit any
exchange of Rights as contemplated in accordance with Section 24(a), the
Company shall either take such action as may be necessary to authorize
additional Common Shares for issuance upon exchange of the Rights or
alternatively, at the option of a majority of the Board of Directors, with
respect to each Right (i) pay cash in an amount equal to the Current Value (as
hereinafter defined), in lieu of issuing Common Shares in exchange therefor, or
(ii) issue debt or equity securities or a combination thereof, having a value
equal to the Current Value, in lieu of issuing Common Shares in exchange for
each such Right, where the value of such securities shall be determined by a
nationally recognized investment banking firm selected by majority vote of the
Board of Directors, or (iii) deliver any combination of cash, property, Common
Shares and/or other securities having a value equal to the Current Value in
exchange for each Right. For purposes of this Section 24(c) only, the Current
Value shall mean the product of the Current Per Share Market Price of Common
Shares on the date of the occurrence of the event described above in
subparagraph (a), multiplied by the number of Common Shares for which the Right
otherwise would be exchangeable if there were sufficient shares available. To
the extent that the Company determines that some action need be taken pursuant
to clauses (i), (ii) or (iii) of this Section 24(c), the Board of Directors may
temporarily suspend the exercisability of the Rights for a period of up to sixty
(60) days following the date on which the event described in Section 24(a) shall
have occurred, in order to seek any authorization of additional Common Shares
and/or to decide the appropriate form of distribution to be made pursuant to the
above provision and to determine the value thereof. In the event of any such
suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended.

                  (d) The Company shall not be required to issue fractions of
Common Shares or to distribute certificates which evidence fractional Common
Shares. In lieu of such fractional Common Shares, there shall be paid to the
registered holders of the Rights Certificates with regard to which such
fractional Common Shares would otherwise be issuable, an amount in cash equal to
the same fraction of the current market value of a whole Common Share (as
determined pursuant to the second sentence of Section 1(j) hereof).

                  (e) The Company may, at its option, by majority vote of the
Board of Directors, at any time before any Person has become an Acquiring
Person, exchange all or part of the then outstanding Rights for rights of
substantially equivalent value, as determined reasonably and with good faith by
the

                                      -32-
<PAGE>   36
Board of Directors, based upon the advice of one or more nationally recognized
investment banking firms.

                  (f) Immediately upon the action of the Board of Directors
ordering the exchange of any Rights pursuant to subsection 24(e) of this Section
24 and without any further action and without any notice, the right to exercise
such Rights shall terminate and the only right thereafter of a holder of such
Rights shall be to receive that number of rights in exchange therefor as has
been determined by the Board of Directors in accordance with subsection 24(e)
above. The Company shall give public notice of any such exchange; provided,
however, that the failure to give, or any defect in, such notice shall not
affect the validity of such exchange. The Company shall mail 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 transfer agent for the Common Shares
of the Company. 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 Rights will be
effected.

         Section 25.  Notice of Certain Events.

                  (a) In case the Company shall propose to effect or permit to
occur any Triggering Event or Section 13 Event, the Company shall give notice
thereof to each holder of Rights in accordance with Section 26 hereof at least
twenty (20) days prior to occurrence of such Triggering Event or such Section 13
Event.

                  (b) In case any Triggering Event or Section 13 Event shall
occur, then, in any such case, the Company shall as soon as practicable
thereafter give to each holder of a Rights Certificate, in accordance with
Section 26 hereof, a notice of the occurrence of such event, which shall specify
the event and the consequences of the event to holders of Rights under Sections
11(a)(ii) and 13 hereof.

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

Company or the Rights Agent to the holder of any Rights Certificate shall be
sufficiently given or made if sent by first-class mail, postage prepaid,
addressed to such holder at the address of such holder as shown on the registry
books of the Company.

         Section 27. Supplements and Amendments. Prior to the occurrence of a
Distribution Date, the Company may supplement or amend this Agreement in any
respect without the approval of any holders of Rights and the Rights Agent
shall, if the Company so directs, execute such supplement or amendment. From and
after the occurrence of a Distribution Date, the Company and the Rights Agent
may from time to time supplement or amend this Agreement without the approval of
any holders of Rights in order to (i) cure any ambiguity, (ii) correct or
supplement any provision contained herein which may be defective or inconsistent
with any other provisions herein, (iii) shorten or lengthen any time period
hereunder or (iv) to change or supplement the provisions hereunder in any manner
that the Company may deem necessary or desirable and that shall not adversely
affect the interests of the holders of Rights (other than an Acquiring Person or
an Affiliate or Associate of an Acquiring Person); provided, this Agreement may
not be supplemented or amended to lengthen, pursuant to clause (iii) of this
sentence, (A) a time period relating to when the Rights may be redeemed at such
time as the Rights are not then redeemable or (B) any other time period unless
such lengthening is for the purpose of protecting, enhancing or clarifying the
rights of, and/or the benefits to, the holders of Rights (other than an
Acquiring Person or an Affiliate or Associate of an Acquiring Person). Upon the
delivery of a certificate from an appropriate officer of the Company that states
that the proposed supplement or amendment is in compliance with the terms of
this Section 27, the Rights Agent shall execute such supplement or amendment.
Prior to the Distribution Date, the interests of the holders of Rights shall be
deemed coincident with the interests of the holders of Common Shares.

         Section 28. Successors.  All the covenants and provisions of this
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. Determinations and Actions by the Board of Directors, etc.
For all purposes of this Agreement, any calculation of the number of Common
Shares outstanding at any particular time, including for purposes of determining
the particular percentage of such outstanding Common Shares of which any Person
is the Beneficial Owner, shall be made in accordance with the last sentence of
Rule

The Board of Directors of the Company shall have the exclusive power and
authority to administer this Agreement and to exercise all rights and powers
specifically granted to the Board, or the Company, or as may be necessary or
advisable in the administration of this Agreement, including, without
limitation, the right and power to (i) interpret the provisions of this
Agreement and (ii) make all determinations deemed necessary or advisable for the
administration of this Agreement (including a determination to redeem or not
redeem the Rights or to amend the Agreement). All such actions, calculations,
interpretations and determinations (including, for purposes of clause (y) below,
all omissions with respect to the foregoing) which are done or made by the Board
in good faith, shall (x) be final, conclusive and binding on the Company, the
Rights Agent, the holders of the Rights Certificates and all other parties and
(y) not subject the Board to any liability to the holders of the Rights.

         Section 30. Benefits of this Agreement. Nothing in this Agreement shall
be construed to give to any Person other than the Company, the Rights Agent and
the registered holders of the Rights Certificates (and, prior to the
Distribution Date, the Common Shares) any legal or equitable right, remedy or
claim under this Agreement; but this Agreement shall be for the sole and
exclusive benefit of the Company, the Rights Agent and the registered holders of
the Rights Certificates (and, prior to the Distribution Date, the Common
Shares).

         Section 31. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated;
provided, however, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and the Board of
Directors of the Company determines in its good faith judgment that severing the
invalid language from this Agreement would adversely affect the purpose or
effect of this Agreement, the right of redemption set forth in Section 23 hereof
shall be reinstated and shall not expire until the Close of Business on the
tenth day following the date of such determination by the Board of Directors.

         Section 32. Governing Law. This Agreement and each Right and each
Rights Certificate issued hereunder shall be deemed to be a contract made under

                                AND PRIVILEGES OF
                     SERIES A PARTICIPATING PREFERRED STOCK
                         OF CARDIAC PATHWAYS CORPORATION


         The undersigned, William N. Starling and Chris F. Fennell do hereby
certify:

         1.       That they are the duly elected and acting President and
Secretary, respectively, of Cardiac Pathways Corporation, a Delaware corporation
(the "Corporation").

         2. That pursuant to the authority conferred upon the Board of Directors
by the Restated Certificate of Incorporation of the said Corporation, the said
Board of Directors on April 22, 1997 adopted the following resolution creating a
series of 30,000 shares of Preferred Stock designated as Series A Participating
Preferred Stock:

         "RESOLVED, that pursuant to the authority vested in the Board of
Directors of the corporation by the Restated Certificate of Incorporation, the
Board of Directors does hereby provide for the issue of a series of Preferred
Stock of the Corporation and does hereby fix and herein state and express the
designations, powers, preferences and relative and other special rights and the
qualifications, limitations and restrictions of such series of Preferred Stock
as follows:

         Section 1. Designation and Amount. The shares of such series shall be
designated as "Series A Participating Preferred Stock." The Series A
Participating Preferred Stock shall have a par value of $.001 per share, and the
number of shares constituting such series shall be 30,000.

         Section 2. Proportional Adjustment. In the event the Corporation shall
at any time after the issuance of any share or shares of Series A Participating
Preferred Stock (i) declare any dividend on the Common Stock of the Corporation
("Common Stock") payable in shares of Common Stock, (ii) subdivide the
outstanding Common Stock or (iii) combine the outstanding Common Stock into a
smaller number of shares, then in each such case the Corporation shall
simultaneously effect a proportional adjustment to the number of outstanding
shares of Series A Participating Preferred Stock.

         Section 3. Dividends and Distributions.

                  (a) Subject to the prior and superior right of the holders of
any shares of any series of Preferred Stock ranking prior and superior to the
shares of Series A Participating Preferred Stock with respect to dividends, the
holders of shares of Series A

                                      
<PAGE>   41
Participating 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, quarterly dividends payable in cash on the last day of January, April,
July and October in each year (each such date being referred to herein as a
"Quarterly Dividend Payment Date"), commencing on the first Quarterly Dividend
Payment Date after the first issuance of a share or fraction of a share of
Series A Participating Preferred Stock, in an amount per share (rounded to the
nearest cent) equal to 1,000 times the aggregate per share amount of all cash
dividends, and 1,000 times the aggregate per share amount (payable in kind) of
all non-cash dividends or other distributions other than a dividend payable in
shares of Common Stock or a subdivision of the outstanding shares of Common
Stock (by reclassification or otherwise), declared on the Common Stock since the
immediately preceding Quarterly Dividend Payment Date, or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series A Participating Preferred Stock.

                  (b) The Corporation shall declare a dividend or distribution
on the Series A Participating Preferred Stock as provided in paragraph (a) above
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock).

                  (c) Dividends shall begin to accrue on outstanding shares of
Series A Participating Preferred Stock from the Quarterly Dividend Payment Date
next preceding the date of issue of such shares of Series A Participating
Preferred Stock, unless the date of issue of such shares is prior to the record
date for the first Quarterly Dividend Payment Date, in which case dividends on
such shares shall begin to accrue from the date of issue of such shares, or
unless the date of issue is a Quarterly Dividend Payment Date or is a date after
the record date for the determination of holders of shares of Series A
Participating Preferred Stock entitled to receive a quarterly dividend and
before such Quarterly Dividend Payment Date, in either of which events such
dividends shall begin to accrue from such Quarterly Dividend Payment Date.
Accrued but unpaid dividends shall not bear interest. Dividends paid on the
shares of Series A Participating Preferred Stock in an amount less than the
total amount of such dividends at the time accrued and payable on such shares
shall be allocated pro rata on a share-by-share basis among all such shares at
the time outstanding. The Board of Directors may fix a record date for the
determination of holders of shares of Series A Participating Preferred Stock
entitled to receive payment of a dividend or distribution declared thereon,
which record date shall be no more than 30 days prior to the date fixed for the
payment thereof.

         Section 4.  Voting Rights.  The holders of shares of Series A
Participating Preferred Stock shall have the following voting rights:

                  (a) Each share of Series A Participating Preferred Stock shall
entitle the holder thereof to 1,000 votes on all matters submitted to a vote of
the stockholders of the Corporation.

                  (b) Except as otherwise provided herein or by law, the holders
of shares of Series A Participating 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 Corporation.

                  (c) Except as required by law, holders of Series A
Participating Preferred Stock shall have no 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 taking any corporate
action.

         Section 5.  Certain Restrictions.

                  (a) The Corporation shall not declare any dividend on, make
any distribution on, or redeem or purchase or otherwise acquire for
consideration any shares of Common Stock after the first issuance of a share or
fraction of a share of Series A Participating Preferred Stock unless
concurrently therewith it shall declare a dividend on the Series A Participating
Preferred Stock as required by Section 3 hereof.

                  (b) Whenever quarterly dividends or other dividends or
distributions payable on the Series A Participating Preferred Stock as provided
in Section 3 are in arrears, thereafter and until all accrued and unpaid
dividends and distributions, whether or not declared, on shares of Series A
Participating Preferred Stock outstanding shall have been paid in full, the
Corporation 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 A Participating Preferred Stock;

                           (ii)     declare or pay dividends on, make any other
distributions on any shares of stock ranking on a parity (either as to dividends
or upon liquidation, dissolution or winding up) with Series A Participating
Preferred Stock, except dividends paid ratably on the Series A Participating
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;

                           (iii)    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 A Participating
Preferred Stock, provided that the Corporation may at any time redeem, purchase
or otherwise acquire shares of any such parity stock in exchange for shares of
any stock of the Corporation ranking junior (either as to dividends or upon
dissolution, liquidation or winding up) to the Series A Participating Preferred
Stock;

                           (iv)     purchase or otherwise acquire for
consideration any shares of Series A Participating Preferred Stock, or any
shares of stock ranking on a parity with the Series A Participating Preferred
Stock, except in accordance with a purchase offer made in writing or by
publication (as determined by the Board of Directors) 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 faith will result in
fair and equitable treatment among the respective series or classes.

                  (c) The Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any shares of
stock of the Corporation unless the Corporation could, under paragraph (a) of
this Section 5, purchase or otherwise acquire such shares at such time and in
such manner.

                                      -3-
<PAGE>   43
         Section 6.  Reacquired Shares. Any shares of Series A Participating
Preferred Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and canceled promptly after the acquisition thereof.
All such shares shall upon their cancellation become authorized but unissued
shares of Preferred Stock and may be reissued as part of a new series of
Preferred Stock to be created by resolution or resolutions of the Board of
Directors, subject to the conditions and restrictions on issuance set forth
herein and, in the Restated Certificate of Incorporation, as then amended.

         Section 7.  Liquidation, Dissolution or Winding Up. Upon any
liquidation, dissolution or winding up of the Corporation, the holders of shares
of Series A Participating Preferred Stock shall be entitled to receive an
aggregate amount per share equal to 1000 times the aggregate amount to be
distributed per share to holders of shares of Common Stock plus an amount equal
to any accrued and unpaid dividends on such shares of Series A Participating
Preferred Stock.

         Section 8.  Consolidation, Merger, etc. In case the Corporation 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 the shares of
Series A Participating Preferred Stock shall at the same time be similarly
exchanged or changed in an amount per share equal to 1,000 times the aggregate
amount of stock, securities, cash and/or any other property (payable in kind),
as the case may be, into which or for which each share of Common Stock is
changed or exchanged.

         Section 9.  No Redemption. The shares of Series A Participating
Preferred Stock shall not be redeemable.

         Section 10. Ranking. The Series A Participating Preferred Stock shall
rank junior to all other series of the Corporation's Preferred Stock as to the
payment of dividends and the distribution of assets, unless the terms of any
such series shall provide otherwise.

         Section 11. Amendment. The Restated Certificate of Incorporation of the
Corporation shall not be further amended in any manner which would materially
alter or change the powers, preference or special rights of the Series A
Participating Preferred Stock so as to affect them adversely without the
affirmative vote of the holders of a majority of the outstanding shares of
Series A Participating Preferred Stock, voting separately as a class.

         Section 12. Fractional Shares.  Series A Participating Preferred Stock
may be issued in fractions of a share which shall entitle the holder, in
proportion to such holder's fractional shares, to exercise voting rights,
receive dividends, participate in distributions and to have the benefit of all
other rights of holders of Series A Participating Preferred Stock.

         RESOLVED FURTHER, that the President or any Vice President and the
Secretary or any Assistant Secretary of this corporation be, and they hereby
are, authorized and directed to prepare and file a Certificate of Designation of
Rights, Preferences and Privileges in accordance with the foregoing

                                      -4-

may deem necessary or appropriate to carry out the intent of the foregoing
resolution."

in the foregoing Certificate of Designation are true and correct of our own
knowledge.

                                  SUMMARY OF RIGHTS

<S>                       <C>
DISTRIBUTION AND          The Board of Directors has declared a dividend of one Right for
TRANSFER OF RIGHTS;       each share of Cardiac Pathways Corporation Common Stock
RIGHTS CERTIFICATE:       outstanding.  Prior to the Distribution Date referred to below, the
                          Rights will be evidenced by and trade with the certificates for the Common
                          Stock. After the Distribution Date, Cardiac Pathways Corporation (the
                          "COMPANY") will mail Rights certificates to the Company's
                          stockholders and the Rights will  become transferable apart from the
                          Common Stock.

DISTRIBUTION DATE:        Rights will separate from the Common Stock and become exerci-
                          sable following (a) the tenth day after a person or group acquires
                          beneficial ownership of 15% or more of the Company's Common
                          Stock or (b) the tenth business day (or such later date as may be
                          determined by the Company's Board of Directors) after a person
                          or group announces a tender or exchange offer, the consummation
                          of which would result in ownership by a person or group of 15%
                          or more of the Company's Common Stock.

PREFERRED STOCK           After the Distribution Date, each Right will entitle the holder to
PURCHASABLE UPON          purchase for $125.00 (the "EXERCISE PRICE"), a fraction of a share
EXERCISE OF RIGHTS:       of the Company's Preferred Stock with economic terms similar to
                          that of one share of the Company's Common Stock.

FLIP-IN:                   If an acquiror (an "ACQUIRING PERSON") obtains 15% or more of the
                           Company's Common Stock then each Right (other than Rights owned by an
                           Acquiring Person or its affiliates) will entitle the holder thereof to
                           purchase, for the Exercise Price, a number of shares of the Company's
                           Common Stock having a then current market value of twice the Exercise
                           Price.

FLIP-OVER:                 If, after an Acquiring Person obtains 15% or more of the
                           Company's Common Stock, (a) the Company merges into another
                           entity, (b) an acquiring entity merges into the Company or (c) the
                           Company sells more than 50% of the Company's assets or
                           earning power, then each Right (other than Rights owned by an
                           Acquiring Person or its affiliates) will entitle the holder thereof
                           to purchase, for the Exercise Price, a number of shares of
                           Common Stock of the person engaging in the transaction having a then
                           current market value of twice the Exercise Price.
