Item 1.  DESCRIPTION OF SECURITIES TO BE REGISTERED.

         On August 14, 1996, pursuant to a Preferred Shares Rights Agreement
(the "Rights Agreement") between Circon Corporation (the "Company") and
ChaseMellon Shareholder Services, L.L.C., as Rights Agent (the "Rights Agent"),
the Company's Board of Directors declared a dividend of one right (a "Right") to
purchase one one-thousandth share of the Company's Series A Participating
Preferred Stock ("Series A Preferred") for each outstanding share of Common
Stock, $.01 par value ("Common Shares"), of the Company.  The dividend is
payable on August 26, 1996 (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 $70.00 (the "Purchase Price"), subject to adjustment.

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


                                         -2-

<PAGE>

RIGHTS EVIDENCED BY COMMON SHARE CERTIFICATES

    The Rights will not be exercisable until the Distribution Date (defined
below).  Certificates for the Rights ("Rights Certificates") will not be sent to
shareholders and the Rights will attach to and trade only together with the
Common Shares.  Accordingly, Common Share certificates outstanding on the Record
Date (together with the Summary of Rights being distributed by the Company to 
shareholders of record) will evidence the Rights related thereto, and Common 
Share certificates issued after the Record Date will contain a notation 
incorporating the Rights Agreement by reference. Until the Distribution Date 
(or earlier redemption or expiration of the Rights), the surrender or 
transfer of any certificates for Common Shares, outstanding as of the Record 
Date, even without notation or a copy of the Summary of Rights, 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 
directors in office prior to any person becoming an Acquiring Person, as 
defined below and their approved successors (the "Continuing Directors")) 
following a public announcement that a person or group of affiliated or 
associated persons (an "Acquiring Person") has acquired, or obtained the 
right to acquire, beneficial ownership of 15% or more of the outstanding 
Common Shares, or (ii) 10 business days (or such later date as may be 
determined by a majority of the Continuing Directors) following the 
commencement of, or announcement of an intention to make, a tender offer or 
exchange offer the

                                         -3-

<PAGE>

consummation of which would result in the beneficial ownership by a person or
group of 15% or more of the outstanding Common Shares, provided, however, that
under the foregoing clause (ii), with respect to the unsolicited tender offer 
by USS Acquisition Corp., a wholly-owned subsidiary of United States Surgical 
Corporation for all outstanding Common Shares of the Company as set forth in 
the Schedule 14D-1 filed with the Securities and Exchange Commission on or 
about August 2, 1996, the Rights will separate and become exercisable only at 
such date as is determined by action of a majority of the Continuing 
Directors then in office.  The earlier of such dates is referred to as the 
"Distribution Date."

ISSUANCE OF RIGHTS CERTIFICATES; EXPIRATION OF RIGHTS

    As soon as practicable following the Distribution Date, separate Rights
Certificates will be mailed to holders of record of the Common Shares as of the
close of business on the Distribution Date and such separate Rights Certificates
alone will evidence the Rights from and after the Distribution Date.  All Common
Shares issued prior to 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) August 14,
2006 (the "Final Expiration Date") or (ii) redemption or exchange of the Rights
as described below.


                                         -4-

<PAGE>

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 $70.00 per Right, one one-thousandth share of the
Series A Preferred.

RIGHT TO BUY COMPANY COMMON SHARES

    Unless the Rights are earlier redeemed, in the event that an Acquiring
Person becomes the beneficial owner of 15% or more of the Company's Common
Shares then outstanding, then 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. In the event that the Company does not have 
sufficient Common Shares available for all Rights to be exercised, or 
the Board decides that such action is necessary and not contrary to the 
interests of Rights holders, the Company may instead substitute cash, assets 
or other securities for the Common Shares for which the Rights would 
have been exercisable under this provision or as described below.             

                             -5-

<PAGE>

RIGHT TO BUY ACQUIRING COMPANY STOCK

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

EXCHANGE PROVISION

    At any time after the acquisition by an Acquiring Person of 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.



                                         -6-

<PAGE>

REDEMPTION

    At any time on or prior to the close of business on the earlier of (i) the
10th day following first public announcement that a person has become an 
Acquiring Person (the "Share Acquisition Date") or such later date as may be 
determined by a majority of the Continuing Directors and publicly announced 
by the Company, or (ii) the Final Expiration Date of the Rights, the Company 
may redeem the Rights in whole, but not in part, at a price of $0.01 per 
Right.

ADJUSTMENTS TO PREVENT DILUTION

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

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.


                                         -7-

<PAGE>

NO STOCKHOLDERS' RIGHTS PRIOR TO EXERCISE

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

AMENDMENT OF RIGHTS AGREEMENT

    The provisions of the Rights Agreement may be supplemented or amended by
the Board of Directors in any manner prior to a person becoming an Acquiring 
Person. After such date, the provisions of the Rights Agreement may be 
amended by the Board in order to cure any ambiguity, defect or inconsistency, 
to make changes which do not adversely affect the interests of holders of 
Rights (excluding the interests of any Acquiring Person), or to shorten or 
lengthen any time period under the Rights Agreement; provided, however, that 
no amendment to adjust the time period governing redemption shall be made at 
such time as the Rights are not redeemable.

RIGHTS AND PREFERENCES OF THE SERIES A PREFERRED

    Series A Preferred purchasable upon exercise of the Rights will not be
redeemable.  Each share of Series A Preferred will be entitled to an aggregate
dividend of 1,000 times the dividend declared per


                                         -8-

<PAGE>

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 $70,000 per share, plus an amount equal to accrued and unpaid dividends and
distributions thereon, whether or not declared, to the date of such payment.
Following the payment of such amount, no additional distributions shall be made
to the holders of shares of Series A Preferred unless, prior thereto, the
holders of Common Shares shall have received an amount per share equal to the
quotient obtained by dividing  the amount paid to holders of Series A Preferred
by  1,000.  Following the payment of each of these amounts, holders of Series A
Preferred and holders of Common Shares shall receive their ratable and
proportionate share of the remaining assets to be distributed in the ratio of
1000 to 1 with respect to such Series A Preferred and Common Shares, on a per
share basis, respectively. In the event of a consolidation, merger or similar 
transaction by the Company, the holders of the Series A Preferred will be 
entitled to receive an amount per share equal to 1,000 times the aggregate 
amount of cash, securities, or other property for which each Common Share is 
exchanged in such transaction. Each share of Series A Preferred will have 
1,000 votes, voting together with the Common Shares.  These rights are 
protected by customary anti-dilution provisions.

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

CERTAIN ANTI-TAKEOVER EFFECTS

    The Rights approved by the Board are designed to protect and maximize the
value of the outstanding equity interests in the Company and the long-term 
strategic plan of the Company. Takeover attempts pose a threat to the 
Company's long-term strategic plan and may include terms (including price) 
that do not adequately reflect the inherent value of the Company or 
coercive tactics to deprive the Company's Board of Directors and its 
stockholders of

                                         -9-

<PAGE>

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

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

    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 shareholders, 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


                                         -10-

<PAGE>

by the Company's Board of Directors, except pursuant to an offer conditioned
upon the negation, purchase or redemption of the Rights.

                                   RIGHTS AGREEMENT



    Agreement, dated as of  August 14, 1996 between Circon Corporation a
Delaware corporation (the "COMPANY"), and ChaseMellon Shareholder Services,
L.L.C. (the "RIGHTS AGENT").

    Effective as of August 14, 1996 (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 August 26, 1996 (the "RECORD DATE"), each Right representing the
right to purchase one one-thousandth (0.001)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 Designation of Rights, Preferences and Privileges of
Series A Participating Preferred Stock attached hereto as EXHIBIT A, upon the
terms and subject to the conditions herein set forth, and further authorized and
directed the issuance of one Right (as such number may be adjusted pursuant to
the provisions of this Agreement) with respect to each Common Share that shall
become outstanding between the Record Date and the earlier of the Distribution
Date and the Expiration Date (as such terms are hereinafter defined), and in
certain circumstances after the Distribution Date.

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

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

         (a)  "ACQUIRING PERSON" shall mean any Person who or which, together
with all Affiliates and Associates of such Person, shall be the Beneficial Owner
of 15% or more of the Common Shares then outstanding, but shall not include the
Company, any Subsidiary of the Company or any employee benefit plan of the
Company or of any Subsidiary of the Company, or any entity holding Common Shares
for or pursuant to the terms of any such plan.  Notwithstanding the foregoing,
no Person shall be deemed to be an Acquiring Person as the result of an
acquisition of Common Shares by the Company which, by reducing the number of
shares outstanding, increases the proportionate number of shares beneficially
owned by such Person to 15% or more of the Common Shares of the Company then
outstanding; PROVIDED, HOWEVER, that if a Person shall become the Beneficial
Owner of 15% or more of the Common Shares of the Company then outstanding by
reason of share purchases by the Company and shall, after such share purchases
by the Company, become the Beneficial Owner of any additional Common Shares of
the Company (other than pursuant to a dividend or distribution paid or made by
the Company on the outstanding Common Shares in Common Shares or pursuant to a
split or subdivision of the outstanding Common Shares), then such Person shall
be deemed to be an Acquiring Person unless upon becoming the Beneficial Owner of

own 15% or more of the Common Shares of the Company then outstanding.
Notwithstanding the foregoing, (i) if the Board of Directors of the Company
determines in good faith that

<PAGE>

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)  "AFFILIATE" and "ASSOCIATE" shall have the respective meanings

              (ii)  which such Person or any of such Person's Affiliates or
Associates has (A) the right to acquire (whether such right is exercisable

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(c)(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

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

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(c)(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

    Section 3.  ISSUANCE OF RIGHTS CERTIFICATES.

         (a)  Until the Distribution Date, (i) the Rights will be evidenced
(subject to the provisions of Sections 3(b) and 3(c) hereof) by the certificates
for Common Shares registered in the names of the holders thereof (which
certificates shall also be deemed to be Rights Certificates) and not by separate
Rights Certificates and (ii) the right to receive Rights Certificates will be
transferable only in connection with the transfer of Common Shares.  Until the
earlier of the Distribution Date or the Expiration Date, the surrender for
transfer of such certificates for Common Shares shall also constitute the
surrender for transfer of the Rights associated with the Common Shares
represented thereby.  As soon as practicable after the Distribution Date, the
Company will prepare and execute, the Rights Agent will


                                         -5-

<PAGE>

countersign, and the Company will send or cause to be sent (and the Rights Agent
will, if requested, send) by first-class, postage-prepaid mail, to each record
holder of Common Shares as of the close of business on the Distribution Date, at
the address of such holder shown on the records of the Company, a Rights
Certificate, in substantially the form of EXHIBIT B hereto (a "RIGHTS
CERTIFICATE"), evidencing one Right for each Common Share so held, subject to
adjustment as provided herein.  In the event that an adjustment in the number of
Rights per Common Share has been made pursuant to Section 11(a)(i),
Section 11(i) or Section 11(o) hereof, then at the time of distribution of the
Rights Certificates, the Company shall make the necessary and appropriate
rounding adjustments (in accordance with Section 14(a) hereof) so that Rights
Certificates representing only whole numbers of Rights are distributed and cash
is paid in lieu of any fractional Rights.  As of the Distribution Date, the
Rights will be evidenced solely by such Rights Certificates and may be
transferred by the transfer of the Rights Certificates as permitted hereby,
separately and apart from any transfer of one or more Common Shares, and the
holders of such Rights Certificates as listed in the records of the Company or
any transfer agent or registrar for the Rights shall be the record holders
thereof.

         (b)  Prior to or on the Record Date or as soon as practicable
thereafter, the Company will send (or cause to be sent) a copy of a Summary of
Rights in substantially the form of EXHIBIT C hereto (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.  With respect to certificates for Common Shares
outstanding as of the Record Date, until the Distribution Date, the Rights will
be evidenced by such certificates registered in the names of the holders thereof
together with the Summary of Rights.  Until the Distribution Date (or, if
earlier, the Expiration Date), the surrender for transfer of any certificate for
Common Shares outstanding on the Record Date, with or without a copy of the
Summary of Rights, shall also constitute the transfer of the Rights associated
with the Common Stock represented thereby.

         (c)  Unless the Board of Directors by resolution adopted at or before
the time of the issuance (including pursuant to the exercise of rights under the
Company's benefit plans) 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
    CIRCON CORPORATION ("CIRCON") AND CHASEMELLON SHAREHOLDER
    SERVICES, L.L.C. AS THE RIGHTS AGENT, DATED AS OF AUGUST 14, 1996
    (THE "RIGHTS AGREEMENT"), THE TERMS OF WHICH ARE HEREBY INCORPORATED
    HEREIN BY REFERENCE AND A COPY OF WHICH IS ON FILE AT THE PRINCIPAL
    EXECUTIVE OFFICES OF CIRCON.  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.  CIRCON WILL MAIL TO THE HOLDER  OF THIS CERTIFICATE
    A COPY OF THE RIGHTS AGREEMENT


                                         -6-

<PAGE>

    WITHOUT CHARGE AFTER RECEIPT OF A WRITTEN REQUEST THEREFOR.
    UNDER CERTAIN CIRCUMSTANCES SET FORTH IN THE RIGHTS AGREEMENT,
    RIGHTS ISSUED TO, OR HELD BY, ANY PERSON WHO IS, WAS OR BECOMES
    AN ACQUIRING PERSON OR ANY AFFILIATE OR ASSOCIATE THEREOF
    (AS SUCH TERMS ARE DEFINED IN THE RIGHTS AGREEMENT),
    WHETHER CURRENTLY HELD BY OR ON BEHALF OF SUCH PERSON OR BY ANY
    SUBSEQUENT HOLDER, MAY BECOME NULL AND VOID.

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

    Section 4.  FORM OF RIGHTS CERTIFICATES.

         (a)  The Rights Certificates (and the forms of election to purchase
Common Shares and of assignment to be printed on the reverse thereof) shall be
substantially in the form of EXHIBIT B hereto and may have such marks of
identification or designation and such legends, summaries or endorsements
printed thereon as the Company may deem appropriate and as are not inconsistent
with the provisions of this Agreement, or as may be required to comply with any
applicable law or with any rule or regulation made pursuant thereto or with any
rule or regulation of any stock exchange on which the Rights may from time to
time be listed, or to conform to usage.  Subject to the provisions of Section 11
and Section 22 hereof, the Rights Certificates, whenever distributed, shall be
dated as of the Record Date (or in the case of Rights issued with respect to
Common Shares issued by the Company after the Record Date, as of the date of
issuance of such Common Shares) and on their face shall entitle the holders
thereof to purchase such number of one-thousandths of a Preferred Share as shall
be set forth therein at the price set forth therein (such exercise price per one
one-thousandth (0.001) of a Preferred Share being hereinafter referred to as the
"PURCHASE PRICE" and the aggregate exercise price of all Preferred Shares (or
other capital stock) issuable upon exercise of one Right being hereinafter
referred to as the "TOTAL EXERCISE PRICE"), but the number and type of
securities purchasable upon the exercise of each Right and the Purchase Price
shall be subject to adjustment as provided herein.

         (b)  Any Rights Certificate issued pursuant to Section 3(a) or
Section 22 hereof that represents Rights beneficially owned by:  (i) an
Acquiring Person or any Associate or Affiliate of an Acquiring Person, (ii) a
transferee of an Acquiring Person (or of any such Associate or Affiliate) who
becomes a transferee after the Acquiring Person becomes such or (iii) a
transferee of an Acquiring Person (or of any such Associate or Affiliate) who
becomes a transferee prior to or concurrently with the Acquiring Person becoming
such and receives such Rights pursuant to either (A) a transfer (whether or not
for consideration) from the Acquiring Person to holders of equity interests in
such Acquiring Person or to any Person with whom such Acquiring Person has any
continuing agreement, arrangement or


                                         -7-

<PAGE>

understanding regarding the transferred Rights or (B) a transfer which the Board
of Directors of the Company has determined is part of a plan, arrangement or
understanding which has as a primary purpose or effect avoidance of Section 7(e)
hereof, and any Rights Certificate issued pursuant to Section 6 or Section 11
hereof upon transfer, exchange, replacement or adjustment of any other Rights
Certificate referred to in this sentence, shall contain (to the extent feasible)
the following legend:

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

    Section 5.  COUNTERSIGNATURE AND REGISTRATION.

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

<PAGE>

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

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

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 Purchase Price for the number of one-thousandths of a Preferred

to the order of the Company, 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 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 issuable upon exercise of the Rights hereunder
with a depositary agent, requisition from the depositary agent of depositary
receipts representing such number of one-thousandths of a Preferred Share as are
to be purchased (in which case certificates for the Preferred Shares represented
by such receipts shall be deposited by the transfer agent with the depositary
agent) and the Company hereby directs the depositary agent to comply with such
request, (ii) when appropriate, requisition from the Company the amount of cash
to be paid in lieu of issuance of fractional shares in accordance with
Section 14 hereof, (iii) after receipt of such certificates or depositary
receipts, cause the same to be delivered to or upon the order of the registered
holder of such Rights Certificate, registered in such name or names as may be
designated by such holder and (iv) when appropriate, after receipt thereof,
deliver such cash to or upon the order of the registered holder of such Rights
Certificate.  The payment of the Purchase Price (as such amount may be reduced
(including to zero) pursuant to Section 11(a)(iii) hereof) may be made in cash
or by certified bank check or bank draft payable to the order of the Company.
In the event that the Company is obligated to issue other securities of the
Company, pay cash and/or distribute other property pursuant to Section 11(a)
hereof, the Company will make all arrangements necessary so that such other
securities, cash and/or other property are available for distribution 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 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 Board of Directors
of the Company has determined is part of a plan, arrangement or understanding
which has as a primary purpose or effect the avoidance of this Section 7(e) (a
"PRIOR TRANSFEREE") or (iv) any subsequent transferee receiving transferred
Rights from a Post Transferee or a Prior 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 insure that the
provisions of this Section 7(e) and Section 4(b) hereof are complied with, but
shall have no liability to any holder of Rights Certificates or to any other
Person as


                                         -10-

<PAGE>

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 have
(i) completed and signed the certificate contained in the form of election to
purchase set forth on the reverse side of the Rights Certificate surrendered for
such exercise and (ii) provided such additional evidence of the identity of the
Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates
thereof as the Company shall reasonably request.

    Section 8.  CANCELLATION AND DESTRUCTION OF RIGHTS CERTIFICATES.  All
Rights Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or to any of its
agents, be delivered to the Rights Agent for cancellation or in canceled form,
or, if surrendered to the Rights Agent, shall be canceled by it, and no Rights
Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this Agreement.  The Company shall deliver to the
Rights Agent for cancellation and retirement, and the Rights Agent shall so
cancel and retire, any other Rights Certificate purchased or acquired by the
Company otherwise than upon the exercise thereof.  The Rights Agent shall
deliver all 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 and to the extent of
its authorized and unissued shares of Preferred Stock not reserved for another
purpose (and, following the occurrence of a Triggering Event, out of its
authorized and unissued shares of Common Stock and/or other securities), the
number of Preferred Shares (and, following the occurrence of the Triggering
Event, Common Stock 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 has been determined in accordance with 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 of 1933, as
amended (the "SECURITIES ACT"), with respect to the


                                         -11-

<PAGE>

securities purchasable upon exercise of the Rights on an appropriate form,
(ii) cause such registration statement to become effective as soon as
practicable after such filing and (iii) cause such registration statement to
remain effective (with a prospectus at all times meeting the requirements of the
Securities Act) until the earlier of (A) the date as of which the Rights are no
longer exercisable for such securities and (B) the date of expiration of the
Rights.  The Company may temporarily suspend, for a period not to exceed ninety
(90) days after the date set forth in clause (i) of the first sentence of this
Section 9(c), the exercisability of the Rights in order to prepare and file such
registration statement and permit it to become effective.  Upon any such
suspension, the Company shall issue a public announcement stating, and notify
the Rights Agent, that the exercisability of the Rights has been temporarily
suspended, as well as a public announcement and notification to the Rights Agent
at such time as the suspension is no longer in effect.  The Company will also
take such action as may be appropriate under, or to ensure compliance with, the
securities or "blue sky" laws of the various states in connection with the
exercisability of the Rights.  Notwithstanding any provision of this Agreement
to the contrary, the Rights shall not be exercisable in any jurisdiction, unless
the requisite qualification in such jurisdiction shall have been obtained, or an
exemption therefrom shall be available, and until a registration statement has
been declared effective.

         (d)  The Company covenants and agrees that it will take all such
action as may be necessary to ensure that all Preferred Shares delivered upon
exercise of Rights shall, at the time of delivery of the certificates for such
Preferred Shares (subject to payment of the Purchase 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 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 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 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.  PREFERRED SHARES RECORD DATE.  Each person in whose name any
certificate for a number of one-thousandths of a Preferred Share is issued upon
the exercise of Rights shall for all purposes be deemed to have become the
holder of record of Preferred Shares represented thereby on, and such
certificate shall be dated, the date upon which the Rights Certificate
evidencing such Rights was duly surrendered and payment of the Purchase Price
multiplied by the number of one-thousandths of a Preferred Share 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 Preferred Shares 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 Preferred Shares 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


                                         -12-

<PAGE>

of Preferred Shares for which the Rights shall be exercisable, including,
without limitation, the right to vote, to receive dividends or other
distributions or to exercise any preemptive rights, and shall not be entitled to
receive any notice of any proceedings of the Company, except as provided herein.

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

         (a)       (i)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(a) and Section 7(e) hereof: (1)
each of the Rights outstanding at the time of the record date for such dividend
or the effective date of such subdivision, combination or reclassification shall
be proportionately adjusted to that number of Rights (calculated to the nearest
one ten-thousandth (1/10,000) of a Right) equal to a fraction (the "EXCHANGE
RATIO"), the numerator of which shall be the total number of Preferred Shares or
shares of capital stock outstanding immediately following such subdivision,
combination or reclassification and the denominator of which shall be the total
number of Preferred Shares outstanding immediately prior to such time, and the
number of Rights that shall thereafter be issued with respect to each Common
Share or share of such other capital stock that shall become outstanding
thereafter prior to the Distribution Date shall be equal to one Right multiplied
by the Exchange Ratio (subject to further adjustment pursuant to the provisions
of this Agreement); (2) the Purchase Price in effect at the time of the record
date for such dividend or of the effective date of such subdivision, combination
or reclassification shall be adjusted so that the Purchase Price thereafter
shall equal the result obtained by dividing the Purchase Price in effect
immediately prior to such time by the Exchange Ratio; 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 Preferred Shares or
shares of such other capital stock issuable upon the exercise of each Right
shall remain unchanged immediately after such event, but, in the event of a
reclassification, the kind of shares issuable upon the exercise of each Right
immediately after such reclassification shall be adjusted to be the kind of
shares of such other capital stock issued in such reclassification, rather than
Preferred Shares.  If an event occurs which would require an adjustment under
both this Section 11(a)(i) and Section 11(a)(ii) hereof, the adjustment provided
for in this Section 11(a)(i) shall be in addition to, and shall be made prior
to, any adjustment required pursuant to Section 11(a)(ii) hereof.

         (ii)   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 Total Exercise
Price applicable 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


                                         -13-

<PAGE>

result obtained by dividing the then-current Total Exercise Price by 50% of
the current per share market price (determined pursuant to Section 11(d) hereof)
for Common Shares on the date of occurrence of the Triggering Event (such number
of shares being hereinafter referred to as the "ADJUSTMENT SHARES"), PROVIDED,
HOWEVER, that the Purchase Price (and thereby the Total 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(f) hereof to reflect any events occurring in respect of the Common Stock of
the Company after the occurrence of such Triggering Event.

         (iii)  In lieu of issuing Common Shares in accordance with
Section 11(a)(ii) hereof, the Company may, if the 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
Purchase Price (such excess, the "SPREAD") and (B) with respect to each such
Right as determined by the Board of Directors, make adequate provision to
substitute for such Common Shares, upon exercise of the Rights, (1) cash, (2) a
reduction in the Purchase Price, (3) other equity securities of the Company
(including, without limitation, shares or units of shares of any series of
preferred stock which the Board of Directors of the Company has deemed to have
the same value as Common Shares (such shares or units of shares of preferred
stock are herein called "common stock equivalents")), except to the extent that
the Company has not obtained any necessary stockholder or regulatory approval
for such issuance, (4) debt securities of the Company, except to the extent that
the Company has not obtained any necessary stockholder or regulatory approval
for such issuance, (5) other assets, or (6) any combination of the foregoing,
having an aggregate value equal to the Current Value, where such aggregate value
has been determined by the Board of Directors of the Company based upon the
advice of a nationally recognized investment banking firm selected by the Board
of Directors of the Company; PROVIDED, HOWEVER, if the Company shall not have
made adequate provision to deliver value pursuant to clause (B) above within
thirty (30) days following the later of (x) the first occurrence of a 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 Purchase 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 Board of
Directors of the Company 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


                                         -14-

<PAGE>

shall apply uniformly to all outstanding Rights and (y) may suspend the
exercisability of the Rights until the expiration of the Substitution Period in
order to seek any authorization of additional shares, to take any action to
obtain any required regulatory approval and/or to decide the appropriate form of
distribution to be made pursuant to such first sentence and to determine the
value thereof.  In the event of any such suspension, the Company shall issue a
public announcement stating that the exercisability of the Rights has been
temporarily suspended, as well as a public announcement at such time as the
suspension is no longer in effect.  For purposes of this Section 11(a)(iii), the
value of the Common Shares shall be the current per share market price (as
determined pursuant to Section 11(d) hereof) 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 Common Shares or of any class or series of Equivalent Shares
entitling such holders (for a period expiring within forty-five (45) calendar
days after such record date) to subscribe for or purchase Common Shares or
Equivalent Shares or securities convertible into Common Shares or Equivalent
Shares at a price per share (or having a conversion price per share, if a
security convertible into Common Shares or Equivalent Shares) less than the then
current per share market price of the Common Shares or Equivalent Shares (as
defined in Section 11(d)) on such record date, then, in each such case, the
Purchase Price to be in effect after such record date shall be determined by
multiplying the Purchase Price in effect immediately prior to such record date
by a fraction, the numerator of which shall be the number of Common Shares and
Equivalent Shares (if any) outstanding on such record date, plus the number of
Common Shares or Equivalent Shares, as the case may be, which the aggregate
offering price of the total number of Common Shares or Equivalent Shares, as the
case may be, so to be offered (and/or the aggregate initial conversion price of
the convertible securities so to be offered) would purchase at such current
market price, and the denominator of which shall be the number of Common Shares
and Equivalent Shares (if any) outstanding on such record date, plus the number
of additional Common 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).  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 Board of Directors of the Company, whose determination shall be described
in a statement filed with the Rights Agent and shall be binding on the Rights
Agent and the holders of the Rights.  Common 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 Purchase Price shall be adjusted to be the
Purchase Price which would then be in effect if such record date had not been
fixed.

         (c)  In case the Company shall, at any time after the date of this
Agreement, fix a record date for the making of a distribution to all holders of
the Common 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 Common Shares) or subscription rights, options or warrants (excluding
those referred to in Section 11(b)), then, in each such


                                         -15-

<PAGE>

case, the Purchase Price to be in effect after such record date shall be
determined by multiplying the Purchase Price in effect immediately prior to such
record date by a fraction, the numerator of which shall be the current market
price (as determined pursuant to Section 11(d) hereof) of a Common Share or an
Equivalent Share on such record date, less the fair market value per Common
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 Common Share or Equivalent Share, as the case may be, and the
denominator of which shall be such current market price (as determined pursuant
to Section 11(d) hereof) of a Common Share or Equivalent Share on such record
date.  Such adjustments shall be made successively whenever such a record date
is fixed, and in the event that such distribution is not so made, the Purchase
Price shall be adjusted to be the Purchase Price which would have been in effect
if such record date had not been fixed.

         (d)  For the purpose of any computation hereunder, other than
computations made pursuant to Section 11(a)(iii) hereof, the "current per share
market price" of any security (a "SECURITY" for the purpose of this
Section 11(d)) on any date shall be deemed to be the average of the daily
closing prices per share of such Security for the thirty (30) consecutive
Trading Days (as such term is hereinafter defined) 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 requisite thirty (30) Trading Day
or ten (10) Trading Day period, after the ex-dividend date for such dividend or
distribution, or the record date for such subdivision, combination or
reclassification, then, and in each such case, the current per share market
price shall be appropriately adjusted to reflect the current market price per
share equivalent of such Security.  The closing price for each day shall be the
last sale price, regular way, or, in case no such sale takes place on such day,
the average of the closing bid and asked prices, regular way, in either case as
reported in the principal consolidated transaction reporting system with respect
to securities listed or admitted to trading on the New York Stock Exchange or,
if the Security is not listed or admitted to trading on the New York Stock
Exchange, as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national securities exchange
on which the Security is listed or admitted to trading or, if the Security is
not listed or admitted to trading on any national securities exchange, the last
sale price or, if such last sale price is not reported, the average of the high
bid and low asked prices in the over-the-counter market, as reported by the
National Association of Securities Dealers, Inc. Automated Quotations System
("NASDAQ") or such other system then in use, or, if on any such date the
Security is not quoted by any such organization, the average of the closing bid
and asked prices as furnished by a professional market maker making a market in
the Security selected by the Board of Directors of the Company.  If on any such
date no market maker is making a market in the Common Shares, the fair value of
such shares on such date as determined in good faith by the Board of Directors
of the Company shall be used.  The term "TRADING DAY" shall mean a day on which
the principal national securities exchange on which the Security is listed or
admitted to trading is open for


                                         -16-

<PAGE>

the transaction of business or, if the Security is not listed or admitted to
trading on any national securities exchange, a Business Day.  If the Common
Shares are not publicly held or so listed or traded, "current per share market
price" shall mean the fair value per share as determined in good faith by the
Board of Directors of the Company, whose determination shall be described in a
statement filed with the Rights Agent and shall be conclusive for all purposes.

         (e)  Anything herein to the contrary notwithstanding, no adjustment in
the Purchase Price shall be required unless such adjustment would require an
increase or decrease of at least 1% in the Purchase Price; PROVIDED, HOWEVER,
that any adjustments which by reason of this Section 11(e) are not required to
be made shall be carried forward and taken into account in any subsequent
adjustment.  All calculations under this Section 11 shall be made to the nearest
cent or to the nearest 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(e), any adjustment required by this
Section 11 shall be made no later than the earlier of (i) three (3) years from
the date of the transaction which requires such adjustment or (ii) the
Expiration Date.

         (f)  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 Purchase Price and Total 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 Common Shares contained in
Sections 11(a), (b), (c), (e), (h), (i), (j), (k), (l) and (m), 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.

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

         (h)  Unless the Company shall have exercised its election as provided
in Section 11(i), upon each adjustment of the Purchase Price as a result of the
calculations made in Section 11(b), each Right outstanding immediately prior to
the making of such adjustment shall thereafter evidence the right to purchase,
at the adjusted Purchase Price, that number of 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 Purchase Price in effect immediately prior to such
adjustment of the Purchase Price, and (ii) dividing the product so obtained by
the Purchase Price in effect immediately after such adjustment of the Purchase
Price.

         (i)  The Company may elect on or after the date of any adjustment of
the Purchase Price as a result of the calculations made in Section 11(b) to
adjust the number of Rights, in substitution for any adjustment in the number of
Preferred Shares purchasable upon the exercise of a Right.  Each of the Rights
outstanding after such adjustment of the number of Rights shall be exercisable
for the number of one-thousandths of a Preferred Share for which a Right was
exercisable immediately prior to such


                                         -17-

<PAGE>

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

         (j)  Irrespective of any adjustment or change in the Purchase Price or
the number of Preferred Shares issuable upon the exercise of the Rights, the
Rights Certificates theretofore and thereafter issued may continue to express
the Purchase 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.

         (k)  Before taking any action that would cause an adjustment reducing
the Purchase 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 Purchase Price.

         (l)  In any case in which this Section 11 shall require that an
adjustment in the Purchase Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event the 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 Purchase Price in effect prior to such adjustment; PROVIDED, HOWEVER, that
the Company shall deliver to such holder a due bill or other appropriate
instrument evidencing such holder's right to receive such additional shares
(fractional or otherwise) upon the occurrence of the event requiring such
adjustment.


                                         -18-

         (m)  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 Purchase 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.

         (n)  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.

         (o)  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) each of the Rights
outstanding at the time of the record date for such dividend or the effective
date of such subdivision, combination or reclassification shall be
proportionately adjusted to that number of Rights (calculated to the nearest one
ten-thousandth (1/10,000) of a Right) equal to a fraction (the "EXCHANGE
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, and the number of Rights that shall thereafter be issued with respect
to each Common Share or share of other capital stock that shall be issued in a
reclassification of the Common Shares prior to the Distribution Date shall be
equal to the total number of outstanding Rights immediately after such event (as
adjusted pursuant to this clause (1)) divided by the total number of outstanding
Common Shares or shares of such other capital stock immediately after such event
(subject to further adjustment pursuant to the provisions of this Agreement);
(2) the Purchase Price in effect at the time of the record date for such
dividend or of the effective date of such subdivision, combination or
reclassification shall be adjusted so that the Purchase Price thereafter shall
equal the result obtained by dividing the Purchase Price in effect immediately
prior to such time by the Exchange Fraction; 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 share of such other capital stock issuable upon the exercise
of each Right shall remain unchanged immediately after such event, but, in the
event of a reclassification, the kind of shares issuable upon the exercise of
each Right immediately after such reclassification shall be adjusted to be the
kind of shares of such other capital stock issued in such reclassification,
rather than Preferred Shares.

    Section 12.  CERTIFICATE OF ADJUSTED PURCHASE 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 or which complies with Section 11(n) hereof);

              (ii)   any Person (other than a wholly-owned Subsidiary of the
Company in a transaction that complies with Section 11(n) hereof) 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; 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 complies with
Section 11(n) hereof),

                        then, and in each such case, proper provision shall be
made so that

                        (A)  each holder of a Right (except as provided in
Section 7(e) hereof) shall thereafter have the right to receive, upon the
exercise thereof at a price equal to the Total Exercise Price applicable
immediately prior to the occurrence of the Section 13 Event in accordance with
the terms of this Agreement, such number of validly authorized and issued, fully
paid, nonassessable and freely tradeable Common Shares of the Principal Party
(as hereinafter defined), free of any liens, encumbrances, rights of first
refusal or other adverse claims, as shall be equal to the result obtained by
dividing such Total Exercise Price by 50% of the current per share market price
(determined pursuant to Section 11(d) hereof) of the Common Shares of such
Principal Party on the date of consummation of such Section 13 Event, PROVIDED,
HOWEVER, that the Purchase Price (and thereby the Total 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(f) hereof;


                                         -20-

<PAGE>

                        (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;

                        (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.

         (b)  "PRINCIPAL PARTY" shall mean:

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

              (ii)   in the case of any transaction described in clause (iii)
of Section 13(a) hereof, the Person that is the party receiving the greatest
portion of the assets or earning power transferred pursuant to such transaction
or transactions, or, if each Person that is a party to such transaction or
transactions receives the same portion of the assets or earning power so
transferred or if the Person receiving the greatest portion of the assets or
earning power cannot be determined, whichever of such Persons is the issuer of
Common Shares having the greatest aggregate market value of shares outstanding;


                                         -21-

<PAGE>

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 ration 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 (b) hereof, that all rights of first refusal or preemptive
rights in respect of the issuance of Common Shares of such Principal Party upon
exercise of outstanding Rights have been waived, that there are no rights,
warrants, instruments or securities outstanding or any agreements or
arrangements which, as a result of the consummation of such transaction, would
eliminate or substantially diminish the benefits intended to be afforded by the
Rights and that such transaction shall not result in a default by such Principal
Party under this Agreement, and further providing that, as soon as practicable
after the date of such Section 13 Event, such Principal Party will:

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

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

              (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.


                                         -22-

<PAGE>

              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 market price per share thereof (determined pursuant to 11(d) hereof) or
securities exercisable for, or convertible into, Common Shares or Equivalent
Shares of such Principal Party at less than such then current 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.

    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 (except prior
to the Distribution Date).  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 11(d) hereof.


                                         -23-

<PAGE>

         (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 11(d) 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(b), 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 11(d) 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 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:


                                         -24-

<PAGE>

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

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

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

    Section 17.  RIGHTS CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDER.  No
holder, as such, of any Rights Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose to be the holder of the Preferred Shares
or any other securities of the Company which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall anything contained herein
or in any Rights Certificate be construed to confer upon the holder of any
Rights Certificate, as such, any of the rights of a stockholder of the Company
or any right to vote for the election of directors or upon any matter submitted
to stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 25 hereof), or to receive dividends
or subscription rights, or otherwise, until the Right or Rights evidenced by
such Rights Certificate shall have been exercised in accordance with the
provisions hereof.

    Section 18.  CONCERNING THE RIGHTS AGENT.

         (a)  The Company agrees to pay to the Rights Agent reasonable
compensation for all services rendered by it hereunder and, from time to time,
on demand of the Rights Agent, its reasonable expenses and counsel fees and
other disbursements incurred in the administration and execution of this
Agreement and the exercise and performance of its duties hereunder.  The Company
also agrees to indemnify the Rights Agent for, and to hold it harmless against,
any loss, liability or expense, incurred without negligence, bad faith or
willful misconduct on the part of the Rights Agent, for anything done or omitted
by the Rights Agent in connection with the acceptance and administration of this
Agreement, including the costs and expenses of defending against any claim of
liability in the premises.  In no case 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,

                                         -25-

<PAGE>

affidavit, letter, notice, direction, consent, certificate, statement or other
paper or document believed by it to be genuine and to be signed, executed and,
where necessary, verified or acknowledged, by the proper Person or Persons, or
otherwise upon the advice of counsel as set forth in Section 20 hereof.

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

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

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

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

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

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


                                         -26-

<PAGE>

Officer, the President, any Vice President, the Chief Financial Officer, the
Secretary or any Assistant Secretary of the Company and delivered to the Rights
Agent; and such certificate shall be full authorization to the Rights Agent for
any action taken or suffered in good faith by it under the provisions of this
Agreement in reliance upon such certificate.

         (c)  The Rights Agent shall be liable hereunder to the Company and any
other Person only for its own negligence, bad faith or willful misconduct.

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

         (e)  The Rights Agent shall not be under any responsibility in respect
of the validity of this Agreement or the execution and delivery hereof (except
the due execution hereof by the Rights Agent) or in respect of the validity or
execution of any Rights Certificate (except its countersignature thereof); nor
shall it be responsible for any breach by the Company of any covenant or
condition contained in this Agreement or in any Rights Certificate; nor shall it
be responsible for any change in the exercisability of the Rights or any
adjustment in the terms of the Rights (including the manner, method or amount
thereof) provided for in Sections 3, 11, 13, 23 or 24, or the ascertaining of
the existence of facts that would require any such change or adjustment (except
with respect to the exercise of Rights evidenced by Rights Certificates after
receipt by the Rights Agent of a certificate furnished pursuant to Section 12
describing such change or adjustment); nor shall it by any act hereunder be
deemed to make any representation or warranty as to the authorization or
reservation of any Preferred Shares to be issued pursuant to this Agreement or
any Rights Certificate or as to whether any Preferred Shares will, when issued,
be validly authorized and issued, fully paid and nonassessable.

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

         (g)  The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from any
one of the Chairman of the Board, the Chief Executive Officer, the President,
any Vice President, the Chief Financial Officer, the Secretary or any Assistant
Secretary of the Company, and to apply to such officers for advice or
instructions in connection with its duties, and it shall not be liable for any
action taken or suffered by it in good faith in accordance with instructions of
any such officer or for any delay in acting while waiting for those
instructions.  Any application by the Rights Agent for written instructions from
the Company may, at the option of the Rights Agent, set forth in writing any
action proposed to be taken or omitted by the Rights Agent under 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


                                         -27-

<PAGE>

Company actually receives such application, unless any such officer shall have
consented in writing to an earlier date) unless, prior to taking any such action
(or the effective date in the case of an omission), the Rights Agent shall have
received written instructions in response to such application specifying the
action to be taken or omitted.

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

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

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

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

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


                                         -28-

<PAGE>

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 $50 million (such requirement does not apply to the Rights Agent initially
appointed by the Company).  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 Purchase Price and the number or kind or class of shares or other
securities or property purchasable under the Rights Certificates made in
accordance with the provisions of this Agreement.  In addition, in connection
with the issuance or sale of 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 the convertible subordinated debentures of the Company
outstanding at the date hereof or upon the exercise, conversion or exchange of
securities hereinafter issued by the Company and (b) may, in any other case, if
deemed necessary or appropriate by the Board of Directors of the Company, issue
Rights Certificates representing the appropriate number of Rights in connection
with such issuance or sale; PROVIDED, HOWEVER, that (i) no such Rights
Certificate shall be issued and this sentence shall be null and void AB INITIO
if, and to the extent that, such issuance or this sentence would create a
significant risk of or result in material adverse tax consequences to the
Company or the Person to whom such Rights Certificate would be issued or would
create a significant risk of or result in such options' or employee plans' or
arrangements' failing to qualify for otherwise available special tax treatment
and (ii) no such Rights Certificate shall be issued if, and to the extent that,
appropriate adjustment shall otherwise have been made in lieu of the issuance
thereof.

    Section 23.  REDEMPTION.

         (a)  The Company may, at its option and with the approval of the Board
of Directors, at any time prior to the Close of Business on the earlier of
(i) the tenth day following the Shares Acquisition Date or such later date as
may be determined by action of a majority of Continuing Directors then in office
and publicly announced by the Company and (ii) 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


                                         -29-

<PAGE>

(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 (as determined pursuant to
Section 11(d) hereof) 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; PROVIDED, HOWEVER, if the Board of Directors of the Company
authorizes redemption of the Rights on or after the time a Person becomes an
Acquiring Person, then there must be Continuing Directors then in office and
such authorization shall require the concurrence of a majority of such
Continuing Directors.

         (b)  Immediately upon the action of the Board of Directors of the
Company ordering the redemption of the Rights, evidence of which shall have been
filed with the Rights Agent, and without any further action and without any
notice, the right to exercise the Rights will terminate and the only right
thereafter of the 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 (c) below, the Company may, at its option, by majority vote of the
Board of Directors and a majority vote of the Continuing Directors, at any time
after the occurrence of a Triggering Event, exchange all or part of the then
outstanding and exercisable Rights (which shall not include Rights that have
become void pursuant to the provisions of Section 7(e) hereof) for Common Shares
at an exchange ratio of one Common Share per Right, appropriately adjusted to
reflect any stock split, stock dividend or similar transaction occurring after
the date hereof (such exchange ratio being hereinafter referred to as the "RATIO
OF EXCHANGE").  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 (a) of this Section 24 and without
any further action and without any notice, the right to exercise such Rights
shall terminate and the only right thereafter of a holder of such


                                         -30-

<PAGE>

Rights shall be to receive that number of Common Shares equal to the number of
such Rights held by such holder multiplied by the Ratio of Exchange.  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 (determined
pursuant to Section 11(d) on the date of the occurrence of the event described
above in subparagraph (a)) multiplied by the number of Common Shares for which
the Right otherwise would be exchangeable if there were sufficient shares
available.  To the extent that the Company determines that some action need be
taken pursuant to clauses (i), (ii) or (iii) of this Section 24(c), the Board of
Directors may temporarily suspend the exercisability of the Rights for a period
of up to sixty (60) days following the date on which the event described in
Section 24(a) shall have occurred, in order to seek any authorization of
additional Common Shares and/or to decide the appropriate form of distribution
to be made pursuant to the above provision and to determine the value thereof.
In the event of any such suspension, the Company shall issue a public
announcement stating that the exercisability of the Rights has been temporarily
suspended.

         (d)  The Company shall not be required to issue fractions of Common
Shares or to distribute certificates which evidence fractional Common Shares.
In lieu of such fractional Common Shares, there shall be paid to the registered
holders of the Rights Certificates with regard to which such fractional Common
Shares would otherwise be issuable, an amount in cash equal to the same fraction
of the current per share market value of a whole Common Share (as determined
pursuant to the second sentence of Section 11(d) 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


                                         -31-

<PAGE>

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 (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 (e) above.
The Company shall give public notice of any such exchange; PROVIDED, HOWEVER,
that the failure to give, or any defect in, such notice shall not affect the
validity of such exchange.  The Company shall mail a notice of any such exchange
to all of the holders of such Rights at their last addresses as they appear upon
the registry books of the transfer agent for the Common Shares of the Company.
Any notice which is mailed in the manner herein provided shall be deemed given,
whether or not the holder receives the notice.  Each such notice of exchange
will state the method by which the exchange of the Rights will be effected.

    Section 25.  NOTICE OF CERTAIN EVENTS.

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

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

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

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

Agreement by or for the benefit of the Company or the Rights Agent shall bind

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

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

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

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

value $0.01 per share, initially consisting of 40,000 shares, and to the extent

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, subject to the provision for adjustment
hereinafter set forth, 1,000 times the aggregate per share amount of all cash
dividends, and 1,000 times the aggregate per share amount (payable in kind) of
all non-cash dividends or other distributions other than a dividend payable in
shares of Common Stock or a subdivision of the outstanding shares of Common
Stock (by reclassification or otherwise), declared on the Common Stock of the
Corporation (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.  In the event the Corporation shall at any time
after August 14, 1996 (the "Rights Dividend Declaration Date") (i) declare any
dividend on 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 amount to which holders of
shares of Series A Participating Preferred Stock were entitled immediately prior
to such event under the preceding sentence shall be adjusted by multiplying such
amount by a fraction, the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

     (B)    The 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 3.  VOTING RIGHTS.  The holders of shares of Series A Participating
Preferred Stock shall have the following voting rights:

     (A)    Subject to the provision for adjustment hereinafter set forth,
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.  In the event the Corporation shall at any time after the
Rights Dividend Declaration Date (i) declare any dividend on 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 number of votes per share to which holders of shares
of Series A Participating Preferred Stock were entitled immediately prior to
such event shall be adjusted by multiplying such number by a fraction, the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

     (B)    Except as otherwise provided herein 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 4.  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 2 hereof.

     (B)    Whenever quarterly dividends or other dividends or
distributions payable on the Series A Participating Preferred Stock as provided
in Section 2 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, or 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;


                                         -3-

<PAGE>

          (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 4, purchase or otherwise acquire such shares at such time and in
such manner.

  Section 5.  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.

  Section 6.  LIQUIDATION, DISSOLUTION OR WINDING UP.

     (A)    Upon any liquidation (voluntary or otherwise), dissolution or
winding up of the Corporation, no distribution shall be made to the holders of
shares of stock ranking junior (either as to dividends or upon liquidation,
dissolution or winding up) to the Series A Participating Preferred Stock unless,
prior thereto, the holders of shares of Series A Participating Preferred Stock
shall have received  seventy thousand dollars ($70,000) per share, plus an
amount equal to accrued and unpaid dividends and distributions thereon, whether
or not declared, to the date of such payment (the "Series A Liquidation
Preference").  Following the payment of the full amount of the Series A
Liquidation Preference, no additional distributions shall be made to the holders
of shares of Series A Participating Preferred Stock unless, prior thereto, the
holders of shares of Common Stock shall have received an amount per share (the
"Common Adjustment") equal to the quotient obtained by dividing (i) the Series A
Liquidation Preference by (ii) 1,000 (as appropriately adjusted as set forth in
subparagraph (C) below to reflect such events as stock splits, stock dividends
and recapitalization with respect to the Common Stock) (such number in
clause (ii), the "Adjustment Number").  Following the payment of the full amount
of the Series A Liquidation Preference and the Common Adjustment in respect of
all outstanding shares of Series A Participating Preferred Stock and Common
Stock, respectively, holders of Series A Participating


                                         -4-

<PAGE>

Preferred Stock and holders of shares of Common Stock shall receive their
ratable and proportionate share of the remaining assets to be distributed in the
ratio of the Adjustment Number to 1 with respect to such Preferred Stock and
Common Stock, on a per share basis, respectively.

     (B)    In the event, however, that there are not sufficient assets
available to permit payment in full to the Series A Liquidation Preference and
the liquidation preferences of all other series of Preferred Stock, if any,
which rank on a parity with the Series A Participating Preferred Stock, then
such remaining assets shall be distributed ratably to the holders of such parity
shares in proportion to their respective liquidation preferences.  In the event,
however, that there are not sufficient assets available to permit payment in
full of the Common Adjustment, then such remaining assets shall be distributed
ratably to the holders of Common Stock.

     (C)    In the event the Corporation shall at any time after the Rights
Dividend Declaration Date (i) declare any dividend on 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 Adjustment Number in effect immediately prior to such
event shall be adjusted by multiplying such Adjustment Number by a fraction the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

  Section 7.  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 (subject to the provision for
adjustment hereinafter set forth) 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.  In the event the Corporation shall at any time after the Rights
Dividend Declaration Date (i) declare any dividend on 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 amount set forth in the preceding sentence with respect to
the exchange or change of shares of Series A Participating Preferred Stock shall
be adjusted by multiplying such amount by a fraction the numerator of which is
the number of shares of Common Stock outstanding immediately after such event
and the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

  Section 8.  NO REDEMPTION.  The shares of Series A Participating Preferred
Stock shall not be redeemable.

  Section 9.  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 10. AMENDMENT.  The 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 or more of the outstanding shares of Series A
Participating Preferred Stock, voting separately as a class.

  Section 11. FRACTIONAL SHARES.  Series A Participating Preferred Stock may
be issued in fractions of a share which shall entitle the holder, in proportion
to such holder's fractional shares, to exercise voting rights, receive
dividends, participate in distributions and to have the benefit of all other
rights of holders of Series A Participating Preferred Stock.

  RESOLVED FURTHER, that the President or any Vice President and the
Secretary or any Assistant Secretary of this corporation be, and they hereby
are, authorized and directed to prepare and file (or cause to be prepared and
filed) a Certificate of Designation of Rights, Preferences and Privileges in
accordance with the foregoing resolution and the provisions of Delaware law and
to take such actions as they may deem necessary or appropriate to carry out the

                                  SUMMARY OF RIGHTS


DISTRIBUTION AND
TRANSFER OF RIGHTS;
RIGHTS CERTIFICATE:      The Board of Directors has declared a dividend of one
                         Right for each share of Circon Common Stock outstanding
                         as of August 26, 1996.  Prior to the Distribution Date
                         referred to below, the Rights will be evidenced by and
                         trade with the certificates for the Common Stock.
                         After the Distribution Date, Circon Corporation (the 
                         "COMPANY") will mail Rights certificates to the 
                         Company's stockholders and the Rights will become 
                         transferable apart from the Common Stock.

Distribution Date:       Rights will separate from the Common Stock and 
                         become exercisable following the (a) tenth day (or 
                         such later date as may be determined by a majority 
                         of the Directors not affiliated with the acquiring 
                         person or group (the "CONTINUING DIRECTORS")) after 
                         a person or group acquires beneficial ownership of 
                         15% or more of the Company's Common Stock or (b) the 
                         tenth business day (or such later date as may be 
                         determined by the Continuing 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, provided that with respect 
                         to the tender offer by USS Acquisition Corp., a 
                         wholly-owned subsidiary of United States Surgical 
                         Corporation for all outstanding shares of Common 
                         Stock of the Company as set forth in the Schedule 
                         14D-1 filed with the Securities and Exchange 
                         Commission on or about August 2, 1996, the Rights 
                         will separate and become exercisable only at such 
                         date as is determined by action of a majority of the 
                         Continuing Directors.

PREFERRED STOCK
PURCHASABLE UPON
EXERCISE OF RIGHTS:      After the Distribution Date, each Right will entitle
                         the holder to purchase, for $70.00, a fraction of a
                         share of the Company's Preferred Stock with economic
                         terms similar to that of one share of the Company's
                         Common Stock.

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

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

EXCHANGE PROVISION:      At any time after an event triggering the flip-in or
                         flip-over rights and prior to the acquisition by the
                         Acquiring Person of 50% or more of the outstanding
                         Common Stock, the Board of Directors of the Company may
                         exchange the Rights (other than Rights owned by the
                         Acquiring Person or its affiliates), in whole or in
                         part, at an exchange ratio of one Common Share per
                         Right (subject to adjustment).

REDEMPTION OF
THE RIGHTS:              Rights will be redeemable at the Company's option for
                         $0.01 per Right at any time on or prior to the tenth
                         day (or such later date as may be determined by a
                         majority of the Continuing Directors) after public
                         announcement that a person has acquired beneficial
                         ownership of 15% or more of the Company's Common Stock
                         (the "SHARES ACQUISITION DATE").

EXPIRATION OF
THE RIGHTS:              The Rights expire on the earliest of (a) August 14,
                         2006 or (b) exchange or redemption of the Rights as
                         described above.

AMENDMENT OF
TERMS OF RIGHTS:         The terms of the Rights and the Rights Agreement may be
                         amended in any respect without the consent of the
                         Rights holders on or prior to the date when an acquiror
                         obtains 15% or more of the Company's Common Stock;
                         thereafter, the terms of the Rights and the Rights
                         Agreement may be amended without the consent of the
                         Rights holders in order to cure any ambiguities or to
                         make changes which do not adversely affect the
                         interests of Rights holders (other than the Acquiring
                         Person).

VOTING RIGHTS:           Rights will not have any voting rights.

ANTI-DILUTION
PROVISIONS:              Rights will have the benefit of certain customary anti-
                         dilution provisions.

TAXES:                   The Rights distribution should not be taxable for
                         federal income tax purposes.  However, following an
                         event which renders the Rights exercisable or upon
                         redemption of the Rights, stockholders may recognize
                         taxable income.

The foregoing is a summary of certain principal terms of the Stockholders Rights
Plan only and is qualified in its entirety by reference to the detailed terms of
the Rights Agreement dated as of August 14, 1996 between the Company and the
Rights Agent, which are incorporated herein by reference.
