ITEM 1.       DESCRIPTION OF SECURITIES TO BE REGISTERED.

           Pursuant to the Preferred Shares Rights Agreement (the "Rights
Agreement") dated as of February 14, 1997 between CardioThoracic Systems,
Inc. (the "Company") and Norwest Bank Minnesota, N.A., as Rights Agent (the
"Rights Agent"), as amended and restated as of August 30, 1999, the Company's
Board of Directors declared a dividend of one right (a "Right") to purchase
one one-thousandth share of the Company's Series A Participating Preferred
Stock ("Series A Preferred") for each outstanding share of Common Stock
("Common Shares") of the Company. The dividend was paid on February 14, 1997
(the "Record Date") to stockholders of record as of the close of business on
that date. 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 $150.00 (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 4 to
this Registration Statement and is incorporated herein by reference.

         RIGHTS EVIDENCED BY COMMON SHARE CERTIFICATES.  The Rights will not
be exercisable until the Distribution Date (defined below). Until the
Distribution Date, certificates for the Rights ("Rights Certificates") will
not be sent to stockholders; instead, 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 the 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 the 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; and (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 consummation of which would result in the
beneficial ownership by a person or group of 15% or more of the outstanding
Common Shares. The earliest 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. All Common
Shares issued prior to


                                       -2-
<PAGE>

the Distribution Date will be issued with Rights. Common Shares issued after
the Distribution Date may be issued with Rights if such shares are issued (i)
upon the conversion of outstanding convertible debentures or any other
convertible securities issued after adoption of the Rights Agreement or (ii)
pursuant to the exercise of stock options or under employee benefit plans or
arrangements unless such issuance would result in (or create a risk that)
such options, plans or arrangements would not qualify for otherwise available
special tax treatment. Except as otherwise determined by the Board of
Directors, no other Common Shares issued after the Distribution Date will be
issued with Rights. The Rights will expire on the earliest of (i) January 28,
2007 (the "Final Expiration Date"), (ii) redemption or exchange of the Rights
as described below, or (iii) consummation of an acquisition of the Company
satisfying certain conditions by a person who acquired shares pursuant to a
Permitted Offer 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 exercise and the payment of $150.00 per
Right, one one-thousandth share of the Series A Preferred. In the event that
the Company does not have sufficient Series A Preferred available for all
Rights to be exercised, or the Board of Directors 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 Series A
Preferred for which the Rights would have been exercisable under this
provision or as described below.

         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 each
holder of a Right which has not theretofore been exercised (other than Rights
beneficially owned by the Acquiring Person, which will thereafter be void)
will thereafter have the right to receive, upon exercise, Common Shares
having a value equal to two times the Purchase Price. Rights are not
exercisable following the occurrence of an event as described above until such
time as the Rights are no longer redeemable by the Company as set forth below.

         RIGHT TO BUY ACQUIRING COMPANY STOCK.  Unless the Rights are earlier
redeemed, in the event that, after the Shares Acquisition Date (as defined
below), (i) the Company is acquired in a merger or other business combination
transaction, or (ii) the Company consummates a merger or other business
combination transaction in which the Company is the continuing or surviving
corporation, or (iii) 50% or more of the Company's assets or earning power
are sold, each holder of a Right which has not theretofore been exercised
(other than Rights beneficially owned by the Acquiring Person, which will
thereafter be void) will thereafter have the right to receive, upon exercise,
shares of common stock of (i) the corporation acquiring the Company or (ii)
the Company or (iii) the purchaser of 50% or more of the Company's assets or
earning power, respectively, such shares in each case having a value equal to
two times the Purchase Price.

                                       -3-
<PAGE>




     EXCHANGE PROVISION.  At any time after the acquisition by an Acquiring
Person of 15% or more of the Company's outstanding Common Shares and prior to
the acquisition by such Acquiring Person of 50% or more of the Company's
outstanding Common Shares, the Board of 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 15% or more of the Company's outstanding Common Shares (the "Shares
Acquisition Date") 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 $.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.

     CASH PAID INSTEAD OF ISSUING FRACTIONAL SHARES.  No fractional portion
less than integral multiples of one Common Share 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 Common Shares 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
without the approval of Rights holders prior to the close of business on the
date of the acquisition by an Acquiring Person of 15% or more of the
Company's outstanding Common Shares.  After the Distribution Date, the
provisions of the Rights Agreement may be amended by the Board of Directors
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 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


                                      -4-

<PAGE>


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 a minimum preferential liquidation payment
equal to $150,000 per share.  Each share of Series A Preferred will have
1,000 votes, voting together with the Common Shares.  In the event of any
merger, consolidation or other transaction in which the Common Shares are
changed or exchanged, each share of Series A Preferred will be entitled to
receive 1,000 times the amount received per Common Share.  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 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 or to evaluate and protect the
long-term value of the Company.  The Rights are not intended to prevent a
takeover of the Company.  The Rights may be redeemed by the Company at $.01
per Right within ten days (or such later date as may be determined by a
majority of the Board of 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 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.

     On August 30, 1999, in connection with the execution of an Agreement and
Plan of Merger dated August 30, 1999 (the "Merger Agreement"), among the
Company, Guidant Corporation and Clydesdale Acquisition Corp., a wholly-owned
subsidiary of Guidant Corporation, the Company and the Rights Agent entered
into a First Amendment to Amended and Restated Preferred Shares Rights
Agreement, which provides that neither Guidant nor Clydesdale Acquisition
Corp. shall be an Acquiring Person under the Rights Agreement by reason of
the execution of the Merger Agreement or related agreements and that the
Rights Agreement will terminate at the Effective Time (as defined in the
Merger Agreement).

                        PREFERRED SHARES RIGHTS AGREEMENT


         Agreement, dated as of February 14, 1997, and amended and restated as
of August 30, 1999, between CardioThoracic Systems, Inc., a Delaware
corporation, and Norwest Bank Minnesota, N.A.(this "AGREEMENT").

         On January 28, 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 February 14, 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.

         The Board of Directors of the Company has determined that it is in the
best interests of the Company and its stockholders to amend and restate the
Preferred Shares Rights Agreement entered into by the Company and the Rights
Agent as of February 14, 1997 (the "ORIGINAL RIGHTS AGREEMENT"), in order to
remove certain terms restricting the ability of the Company's Board of Directors
to amend the Original Rights Agreement or redeem the Rights issued thereunder
under certain circumstances, and to make certain other changes, and the Rights
Agent has agreed to such amendment and restatement.

         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


<PAGE>


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 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.

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
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
P.M., New York time, on such date; PROVIDED, HOWEVER, that if such date is not a
Business Day it shall mean 5:00 P.M., New York time, on the next succeeding

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

"Security" for purposes of this definition), for all computations other than
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 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

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(k), as appropriately adjusted to reflect
any stock split, stock dividend or similar transaction occurring after the date
hereof, multiplied by 1000. 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

represented thereby. As soon as practicable after the Distribution Date, the
Company will prepare and execute, the Rights Agent will countersign, and the

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

<PAGE>


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. 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
         CARDIOTHORACIC SYSTEMS, INC. AND NORWEST BANK MINNESOTA, N.A., AS THE

         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. CARDIOTHORACIC SYSTEMS, INC. WILL MAIL
         TO THE HOLDER OF THIS CERTIFICATE A COPY OF THE RIGHTS AGREEMENT

         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.

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

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 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 principal office of the Rights Agent. 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 principal office of the Rights Agent, 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 Fifty Dollars ($150.00), 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

                                       -11-
<PAGE>

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 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


                                       -12-
<PAGE>

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 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


                                       -13-
<PAGE>

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.

                (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 the 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.


                                       -14-
<PAGE>

                (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 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.


                                       -15-
<PAGE>

                       (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 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 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
a majority of 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


                                       -16-
<PAGE>

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 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


                                       -17-
<PAGE>

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 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.


                                       -18-
<PAGE>

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 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

                                       -19-
<PAGE>

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.

                (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


                                       -20-
<PAGE>


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


                                      -21-

<PAGE>


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 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


                                      -22-

<PAGE>


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 Section13(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 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,


                                      -23-

<PAGE>


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 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.

                  (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 of the Rights Agent, 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.

                  (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


                                      -27-

<PAGE>


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 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.


                                      -28-

                  (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 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


                                      -29-

<PAGE>


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 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


                                      -30-

<PAGE>

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 earlier of (i) the Distribution
Date and (ii) the Close of Business on the Final Expiration Date, redeem all but
not less than all the then outstanding Rights at a redemption price 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


                                       -31-
<PAGE>

(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) 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 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


                                       -32-
<PAGE>

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 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 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

                                       -34-

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

         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.

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 13d-3(d)(1)(i) of the General Rules and Regulations
under the Exchange Act. 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,

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

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

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

               CERTIFICATE OF DESIGNATIONS OF RIGHTS, PREFERENCES
                                AND PRIVILEGES OF
                     SERIES A PARTICIPATING PREFERRED STOCK
                         OF CARDIOTHORACIC SYSTEMS, INC.

         The undersigned, Richard M. Ferrari and J. Casey McGlynn do hereby
certify:

         1.     That they are the duly elected and acting President and
Secretary, respectively, of CardioThoracic Systems, Inc., a Delaware
corporation (the "CORPORATION").

         2.     That pursuant to the authority conferred upon the Board of
Directors by the Certificate of Incorporation of the said Corporation, the
said Board of Directors on January 28, 1997 adopted the following resolution
creating a series of 20,000 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 $0.001 per share, and
the number of shares constituting such series shall be 20,000.

         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 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 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


<PAGE>

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.

<PAGE>


         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.

                                           Distribution Date, CardioThoracic
                                           Systems, Inc. (the "COMPANY") will
                                           mail Rights certificates to 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
PURCHASABLE UPON                           Right will entitle the holder to

                                           to that of one share of the
                                           Company's Common Stock.

FLIP-IN:                                   If an acquiror (an "ACQUIRING

                                           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

                                           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

                                           which renders the Rights exercisable
                                           or upon redemption of the Rights,
                                           stockholders may recognize taxable
