Item 1.   DESCRIPTION OF SECURITIES TO BE REGISTERED.

    On February 27, 1997, the Board of Directors of Conceptus, Inc. (the 
"Company") declared a dividend of one preferred share purchase right (a 
"Right") for each outstanding share of Common Stock, $0.003 par value (the 
"Common Shares"), of the Company. The dividend is payable on March 26, 
1997 (the "Record Date") to stockholders of record as of the close of 
business on that date.  Each Right entitles the registered holder to purchase 
from the Company one one-thousandth of a share of Series A Participating 
Preferred Stock, $0.003 par value, of the Company (the "Preferred Shares"), 
subject to adjustment, at a price of $80.00 per share, subject to 
adjustment (the "Purchase Price").  The description and terms of the Rights 
are set forth in a Preferred Shares Rights Agreement (the "Rights Agreement") 
dated as of February 27, 1997 between the Company and ChaseMellon Shareholder 
Services, L.L.C., as the Rights Agent (the "Rights Agent").

     The following is a general description only and is subject to the 
detailed terms and conditions of the Rights Agreement.  A copy of the Rights 
Agreement, including the Certificate of Designation, the form of Rights 
Certificate and the Summary of Rights to be provided to stockholders of the 
Company, is attached as Exhibit 1 to this Registration Statement and is 
incorporated herein by reference.

RIGHTS EVIDENCED BY COMMON SHARE CERTIFICATES

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

                                     -2-

<PAGE>

DISTRIBUTION DATE

     The Rights will separate from the Common Shares, certificates for the 
Rights ("Rights Certificates") will be issued and the Rights will become 
exercisable upon the earlier of:  (i) the close of business on the tenth day 
(or such later date as may be determined by a majority of the Board of 
Directors, excluding directors affiliated with the Acquiring Person, as 
defined below (the "Continuing Directors")) following a public announcement 
that a person or group of affiliated or associated persons has acquired, or 
obtained the right to acquire, beneficial ownership of 20% or more of the 
outstanding Common Shares (an "Acquiring Person") or (ii) the close of 
business on the tenth day (or such later date as may be determined by a 
majority of the Continuing Directors) following the commencement of a tender 
offer or exchange offer, the consummation of which would result in the 
beneficial ownership by a person or group of 20% or more of the outstanding 
Common Shares.  The earlier of such dates is referred to as the "Distribution 
Date."

ISSUANCE OF RIGHTS CERTIFICATES, EXPIRATION OF RIGHTS

     As soon as practicable following the Distribution Date, separate Rights 
Certificates will be mailed to holders of record of the Common Shares as of 
the close of business on the Distribution Date and such separate Rights 
Certificates alone will evidence the Rights from and after the Distribution 
Date.  Unless otherwise determined by the Board of Directors, 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 exercise, conversion or exchange of 
securities issued after adoption of the Rights Agreement or (ii) pursuant to 
the exercise of stock options or under any employee benefit plan or 
arrangement.  Except as otherwise determined by the Board of Directors, no 
other Common Shares issued after the Distribution Date will be issued with 
Rights.  In addition, no Common Shares issued after the Distribution Date 
will be issued with Rights if such issuance would result in (or create a 
significant risk of) (i) material adverse tax consequences to the Company or 
the person to whom such Rights Certificate would be issued or (ii) such 
options or plans not qualifying for otherwise available special tax 
treatment.  The Rights will expire on February 26, 2007 (the "Final

                                     -3-

<PAGE>

Expiration Date"), unless the Final Expiration Date is extended or unless the 
Rights are earlier redeemed or exchanged by the Company or expire upon 
consummation of certain mergers, consolidations or sales of assets, as 
described below.

INITIAL EXERCISE OF THE RIGHTS

     Following the Distribution Date, and until the occurrence of one of the 
subsequent events described below, holders of the Rights will be entitled to 
receive, upon exercise and the payment of $80.00 (the "Purchase Price") per 
Right, one one-thousandth of a Preferred Share.

EXCHANGE PROVISION

     At any time after an Acquiring Person has become such and prior to the 
Acquiring Person beneficially owning 20% or more of the outstanding Common 
Shares, 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).

RIGHT TO BUY COMMON SHARES AT HALF PRICE

     Unless the Rights are earlier redeemed or exchanged, in the event that 
an Acquiring Person becomes such, other than pursuant to a tender offer which 
is made for all of the outstanding Common Shares and approved by a majority 
of the Continuing Directors after determining that the offer is both adequate 
and otherwise in the best interests of the Company and its stockholders (a 
"Permitted Offer"), then proper provision will be made so that each holder of 
a Right which has not theretofore been exercised (other than Rights 
beneficially owned by the Acquiring Person, which will thereafter be void) 
will thereafter have the right to receive, upon exercise of a Right, a number 
of Common Shares having a then current value equal to two times the Purchase 
Price.  In the event that the Company does not have a sufficient number of 
Common Shares available, or the Board decides that such action is necessary 
or appropriate and not contrary to the interests of Rights holders, the 
Company may, among other things, instead substitute cash, assets or other 
securities for the Common Shares into which the Rights would have otherwise 
been exercisable.

                                     -4-

<PAGE>

RIGHT TO BUY ACQUIRING COMPANY STOCK AT HALF PRICE

     Similarly, unless the Rights are earlier redeemed or exchanged, in the
event that, after the Shares Acquisition Date (as defined below), (i) the
Company consolidates with or merges into another entity, (ii) another entity
consolidates with or merges into the Company or (iii) the Company sells or
otherwise transfers 50% or more of its consolidated assets or earning power,
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 thereafter be void) will thereafter have the right
to receive, upon exercise, a number of shares of common stock of the acquiring
company having a then current value equal to two times the Purchase Price
(unless the transaction satisfies certain conditions and is consummated with a
person who acquired shares pursuant to a Permitted Offer, in which case the
Rights will expire).

ADJUSTMENTS TO PREVENT DILUTION

     The Purchase Price payable, the number of Rights and the number of
Preferred Shares, Common Shares or other securities or property issuable upon
exercise of the Rights are subject to adjustment from time to time to prevent
dilution 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.

RIGHTS AND PREFERENCES OF THE PREFERRED SHARES

     Preferred Shares purchasable upon exercise of the Rights will not be 
redeemable.  Each Preferred Share will be entitled to an aggregate dividend 
of 1,000 times the dividend declared per Common Share.  In the event of 
liquidation, the holders of the Preferred Shares will be entitled to a 
preferential liquidation payment equal to accrued but unpaid dividends plus 
the greater of $1,000 per share or 1,000 times the aggregate per share amount 
to be distributed to the holders of Common Shares.  Each Preferred Share will 
have 1,000 votes, voting together with the holders of Common Shares, except 
as required by law or the Certificate of Determination of Rights, Preferences 
and Privileges of Series A Participating Preferred Stock.  In the event of 
any merger, consolidation or other transaction in which Common Shares are 

                               -5-

<PAGE>

changed or exchanged, each Preferred Share will be entitled to receive 1,000 
times the amount received per Common Share.  These rights are protected by 
customary anti-dilution provisions.  Because of the nature of the dividend, 
liquidation and voting rights of the Preferred Shares, the value of the one 
one-thousandth interest in a Preferred Share purchasable upon exercise of 
each Right should approximate the value of one Common Share.

REDEMPTION

     At any time prior to the close of business on the earlier of (i) the 
tenth day following the date (the "Shares Acquisition Date") of public 
announcement that an Acquiring Person has become such 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 ("Redemption Price").

NO STOCKHOLDERS' RIGHTS PRIOR TO EXERCISE

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

AMENDMENT OF RIGHTS AGREEMENT

     The provisions of the Rights Agreement may be supplemented or amended by 
the Board of Directors in any manner prior to the Distribution Date without 
the approval of Rights holders.  After the Distribution Date, the provisions 
of the Rights Agreement may be supplemented or amended by the Board in order 
to (i) cure any ambiguity, defect or inconsistency, (ii) to make changes 
which are deemed necessary or advisable and 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 lengthen (A) the time 
period governing redemption shall be made at such time as the Rights are not

                                     -6-

<PAGE>

redeemable or (B) any other period unless for the purpose of protecting, 
enhancing or clarifying the rights of, and/or benefits to, the holders of 
Rights.

CERTAIN ANTI-TAKEOVER EFFECTS

     The Rights approved by the Board are designed to protect and maximize 
the value of the outstanding equity interests in the Company in the event of 
an unsolicited attempt by an acquiror to take over the Company, in a manner 
or on terms not approved by the Board of Directors.  Takeover attempts 
frequently include coercive tactics to deprive a corporation's Board of 
Directors and its stockholders of any real opportunity to determine the 
destiny of the corporation.  The Rights have been declared by the Board in 
order to deter such tactics, including a gradual accumulation of shares in 
the open market of a 20% or greater position to be followed by a merger or a 
partial or two-tier tender offer that does not treat all stockholders 
equally.  These tactics unfairly pressure stockholders, squeeze them out of 
their investment without giving them any real choice and deprive them of the 
full value of their shares.

     The Rights are not intended to prevent a takeover of the Company and 
will not do so.  The Rights are not exercisable in the event of a Permitted 
Offer, as described above.  The Rights may be redeemed by the Company at 
$0.01 Right within ten days (or such later date as may be determined by a 
majority of the Continuing Directors) after the accumulation of 20% or more 
of the Company's outstanding Common Shares by a single acquiror or group.  
Accordingly, the Rights should not preclude any merger or business 
combination approved by the Board of Directors.  Issuance of the Rights does 
not in any way weaken the financial strength of the Company or interfere with 
its business plans. The issuance of the Rights has no immediate dilutive 
effect, will not affect reported earnings per share, should not be taxable to 
the Company or to its stockholders and will not change the way in which the 
Company's shares are presently traded.  The Company's Board of Directors 
believes that the Rights represent a sound and reasonable means of addressing 
the complex issues of corporate policy created by the current takeover 
environment.  However, the Rights may have the effect of rendering more 
difficult or discouraging an acquisition of the Company deemed undesirable by 
the Board of Directors.  The Rights may cause substantial dilution to a 

                                  -7-

<PAGE>

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

                       PREFERRED SHARES RIGHTS AGREEMENT


     Agreement, dated as of February 27, 1997, between Conceptus, Inc., a 
Delaware corporation (the "COMPANY"), and ChaseMellon Shareholder Services, 
L.L.C. (the "RIGHTS AGENT").

     On February 27, 1997 (the "RIGHTS DIVIDEND DECLARATION DATE"), the 
Board of Directors of the Company authorized and declared a dividend of one 
Preferred Share purchase right (a "RIGHT") for each Common Share (as 
hereinafter defined) of the Company outstanding as of the Close of Business 
(as hereinafter defined) on March 26, 1997 (the "RECORD DATE"), each 
Right representing the right to purchase one one-thousandth of a share of 
Series A Participating Preferred Stock (as such number may be adjusted 
pursuant to the provisions of this Agreement), having the rights, preferences 
and privileges set forth in the form of Certificate of 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 20% 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 either (i) 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 20% or 
more of the Common Shares of the Company then outstanding; PROVIDED, HOWEVER, 
that if a Person shall become the Beneficial Owner of 20% 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, then such 
Person shall be deemed to be an Acquiring Person, or (ii) if within eight 
days after such Person would otherwise become an Acquiring Person (but for 
the operation of this clause (ii)), such Person notifies the Board of 
Directors that such Person did so inadvertently and within two days after 
such notification, such Person is the Beneficial Owner of less than 20% of 
the outstanding Common Shares.

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

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

bona fide public offering of securities) for the purpose of acquiring, 
holding, voting (except to the extent contemplated by the proviso to Section 
l(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

     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 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(p) 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

                                     -5-

<PAGE>

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)  On the Record Date or as soon as practicable thereafter, the 
Company will send 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.

     (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 Preferred Shares Rights Agreement between
     Conceptus, Inc. and ChaseMellon Shareholder Services, L.L.C. as the Rights
     Agent, dated as of February 27, 1997 (the "RIGHTS AGREEMENT"), the
     terms of which are hereby incorporated herein by reference and a copy of
     which is on file at the principal executive offices of Conceptus, Inc.
     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. Conceptus, Inc. will mail to the holder of
     this certificate a copy of the Rights Agreement without charge after
     receipt of a written request therefor.  Under certain circumstances set
     forth in the Rights Agreement, Rights issued to, or held by, any Person
     who is, was or becomes an Acquiring Person or any Affiliate or Associate
     thereof (as such terms are defined in the Rights Agreement), whether
     currently held by or on behalf of such Person or by any subsequent holder,
     may become null and void.

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

                                     -6-

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 of a 
Preferred Share being hereinafter referred to as the "PURCHASE PRICE" and the 
aggregate exercise price of all Preferred Shares issuable upon exercise of 
one Right being hereinafter referred to as the "TOTAL EXERCISE PRICE"), but 
the number and type of securities purchasable upon the exercise of each Right 
and the 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 understanding 
regarding the transferred Rights or (B) a transfer that the Board of 
Directors of the Company has determined is part of a plan, arrangement or 
understanding that 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

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 
counter signed 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.

CERTIFICATES; MUTILATED, DESTROYED, LOST OR STOLEN RIGHTS CERTIFICATES.

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

                                     -8-

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.

purchased and an amount equal to any applicable transfer tax required to be 
paid by the holder of such Rights Certificate in accordance with Section 9 
hereof in cash, or by certified check or cashier's check payable 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

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)(iv) 
hereof) may be made in cash or by certified check or cashier's check 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 or a Section 13 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 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 a national securities 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)(iv) 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 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

                                     -11-

<PAGE>

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 depository 
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 depository 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 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.

                                     -12-

<PAGE>

     (a)  (i)  In the event the Company shall at any time after the date of 
this Agreement (A) declare a dividend on the Common Shares payable in Common 
Shares, (B) subdivide the outstanding Common Shares, (C) combine the 
outstanding Common Shares (by reverse stock split or otherwise) into a 
smaller number of Common Shares, or (D) issue any shares of its capital stock 
in a reclassification of the Common Shares (including any such 
reclassification in connection with a consolidation or merger in which the 
Company is the continuing or surviving corporation), then, in each such 
event, except as otherwise provided in this Section 11(a) and Section 7(e) 
hereof: (1) each 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 Common Shares or shares of capital stock issued in such 
reclassification of the Common Shares outstanding immediately following such 
time and the denominator of which shall be the total number of Common 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 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 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, 
proper provision shall be made so that 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 
Agree ment and payment of the then-current Total Exercise Price, in lieu of a 
number of one-thousandths of a Preferred Share, such number of Common Shares 
of the Company as shall equal the result obtained by multiplying the 
then-current Purchase Price by the then number of one-thousandths of a 
Preferred Share for which a Right was exercisable (or would have been 
exercisable if the Distribution Date had occurred) immediately prior to the 
first occurrence of a Triggering Event, and dividing that product by 50% of 
the current per share market price

                                     -13-

<PAGE>


(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").

     (iii)     The right to buy Common Shares of the Company pursuant to 
Section 11(a)(ii) hereof shall not arise as a result of any Person becoming 
an Acquiring Person through an acquisition of Common Shares pursuant to a 
Permitted Offer.

     (iv) 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 Right, 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

                                     -14-

<PAGE>

second sentences of this Section 11(a)(iv), the Company (x) shall provide, 
subject to Section 7(e) hereof, that such action shall apply uniformly to all 
outstanding Rights and (y) may suspend the exercisability of the Rights until 
the expiration of the Substitution Period in order to seek any authorization 
of additional shares, to take any action to obtain any required regulatory 
approval and/or to decide the appropriate form of distribution to be made 
pursuant to such first sentence and to determine the value thereof.  In the 
event of any such suspension, the Company shall issue a public announcement 
stating that the exercisability of the Rights has been temporarily suspended, 
as well as a public announcement at such time as the suspension is no longer 
in effect.  For purposes of this Section 11(a)(iv), 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 deter mination 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


                                     -15-

<PAGE>

evidences of indebt edness 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 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 (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)(iv) 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)(iv) 
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

                                     -16-

<PAGE>


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 
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 thereof, shall be subject to adjust 
ment 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), (1) 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.

                                     -17-

<PAGE>

     (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 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 ten-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.

     (1)  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,

                                     -18-

<PAGE>


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.

     (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 it shall not, at any time 
after the Distribution Date, effect or permit to occur any Triggering Event 
or Section 13 Event, if (i) at the time or immediately after such Triggering 
Event or 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 or (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 and Associates.

     (o)  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.

     (p)  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 
deno minator of which shall be the total number of Preferred Shares 
outstanding immediately prior to such time, and the number of Rights that 
shall

                                     -19-

<PAGE>

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 the Shares Acquisition Date, directly 
or indirectly:

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

    (ii) any Person (other than a Subsidiary of the Company in a transaction 
that complies with Section 11(o) 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

                                     -20-

<PAGE>

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(o) hereof),

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

     (A)  each holder of a Right (except as otherwise provided herein) shall 
thereafter have the right to receive, upon the exercise thereof in accordance 
with the terms of this Agreement, such number of validly authorized and 
issued, fully paid and nonassessable 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 
(1) multiplying the then current Purchase Price by the number of 
one-thousandths of a Preferred Share for which a Right was exercisable 
immediately prior to the first occurrence of a Section 13 Event (or, if a 
Triggering Event has occurred prior to the first occurrence of a Section 13 
Event, multiplying the number of such one-thousandths of a Preferred Share 
for which a Right was exercisable immediately prior to the first occurrence 
of a Triggering Event by the Purchase Price in effect immediately prior to 
such first occurrence) and (2) dividing that product (which, following the 
first occurrence of a Section 13 Event, shall be referred to as the "TOTAL 
EXERCISE PRICE" for each Right and for all purposes of this Agreement) 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;

     (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 assure 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.

     (b)  "PRINCIPAL PARTY" shall mean, in the case of any transaction 
described in clause (i), (ii) or (iii) of Section 13(a), the Person referred 
to therein or such Person's successor, including, if applicable, the Company, 
if it is the surviving corporation), PROVIDED, HOWEVER, that in any such 
case, (i) if such Person is a direct or indirect Subsidiary of another 
Person, "Principal Party" shall refer to such other Person and (ii) in case 
such Person is a Subsidiary, directly or indirectly, of more than one Person, 
"Principal Party" shall refer to whichever of such Persons is the issuer of 
the Common Shares having the greatest aggregate value, and PROVIDED, FURTHER, 
that for purposes of transactions described in clause (iii) hereof, 
"Principal Party" shall refer to that

                                     -21-

<PAGE>

Person receiving the greatest portion of the assets or earning power 
transferred pursuant to such transaction or transactions.

     (c)  If, for any reason, the Rights cannot be exercised for Common 
Shares of such Principal Party as provided in Section 13(a), then each holder 
of Rights shall have the right to exchange its Rights for cash from such 
Principal Party in an amount equal to the number of Common Shares that it 
would otherwise be entitled to purchase times 50% of the current per share 
market price, as determined pursuant to Section 11(d) hereof, of such Common 
Shares of such Principal Party.  If, for any reason, the foregoing 
formulation cannot be applied to determine the cash amount into which the 
Rights are exchangeable, then the Board of Directors, based upon the advice 
of one or more nationally recognized investment banking firms, and based upon 
the total value of the Company, shall determine such amount reasonably and 
with good faith to the holders of Rights.  Any such determination shall be 
final and binding on the Rights Agent.

     (d)  Notwithstanding anything in this Agreement to the contrary, Section 
13 shall not be applicable to a transaction described in clauses (i) and (ii) 
of Section 13(a) if:  (i) such transaction is consummated with a Person or 
Persons who acquired Common Shares pursuant to a Permitted Offer (or a 
wholly-owned Subsidiary of any such Person or Persons); (ii) the price per 
share of Common Shares offered in such transaction is not less than the price 
per share of Common Shares paid to all holders of Common Shares whose shares 
were purchased pursuant to such Permitted Offer; and (iii) the form of 
consideration being offered to the remaining holders of Common Shares 
pursuant to such transaction is the same form as the form of consideration 
paid pursuant to such Permitted Offer.  Upon consummation of any such 
transaction contemplated by this Section 13(d), all Rights hereunder shall 
expire.

     (e)  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 arrange ments 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;

                                     -22-

<PAGE>

     (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.

     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)).

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

Section 14.    FRACTIONAL RIGHTS AND FRACTIONAL SHARES.

     (a)  The Company shall not be required to issue fractions of Rights or 
to distribute Rights Certificates that evidence fractional Rights.  In lieu 
of such fractional Rights, there shall be paid to the registered holders of 
the Rights Certificates with regard to which such fractional Rights would 
otherwise be issuable, an amount in cash equal to the same fraction of the 
current market value of a whole Right.  For the purposes of this Section 
14(a), the current market value of a whole Right shall be the closing price 
of the Rights for the Trading Day immediately prior to the date on which such 
fractional Rights would have been otherwise issuable, as determined pursuant 
to the second sentence of Section 11(d) hereof.

     (b)  The Company shall not be required to issue fractions of Preferred 
Shares (other than fractions that are integral multiples of one 
one-thousandth of a Preferred Share) upon exercise of the Rights or to 
distribute certificates which evidence fractional Preferred Shares (other 
than fractions that are integral multiples of one one-thousandth of a 
Preferred Share).  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 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.

     (c)  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

                                     -23-

<PAGE>


registered holders of the Common Shares); and any registered holder of any 
Rights Certificate (or, prior to the Distribution Date, of the Common 
Shares), without the consent of the Rights Agent or of the holder of any 
other Rights Certificate (or, prior to the Distribution Date, of the Common 
Shares), may, in his or her own behalf and for his or her own benefit, 
enforce, and may institute and maintain any suit, action or proceeding 
against the Company to enforce, or otherwise act in respect of, his or her 
right to exercise the Rights evidenced by such Rights Certificate in the 
manner provided in such Rights Certificate and in this Agreement.  Without 
limiting the foregoing or any remedies available to the holders of Rights, it 
is specifically acknowledged that the holders of Rights would not have an 
adequate remedy at law for any breach of this Agreement and will be entitled 
to specific performance of the obligations under, and injunctive relief 
against actual or threatened violations of, the obligations of any Person 
subject to this Agreement.

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

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

     (b)  after the Distribution Date, the Rights Certificates are 
transferable only on the registry books of the Rights Agent if surrendered at 
the 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 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.

     (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 Common Shares or for other 
securities of the Company, instrument of assignment or transfer, power of 
attorney, endorsement, affidavit, letter, notice, direction, consent, 
certificate, statement or other paper or document 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 
shareholder services 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

                                      -25-

<PAGE>

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 or advice 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 or advice.

     (b)  Whenever in the performance of its duties under this Agreement the 
Rights Agent shall deem it necessary or desirable that any fact or matter 
(including, without limitation, the identity of any Acquiring Person and the 
determination of "current per share market price") be proved or established 
by the Company prior to taking or suffering any action hereunder, such fact 
or matter (unless other evidence in respect thereof be herein specifically 
prescribed) may be deemed to be conclusively proved and established by a 
certificate signed by any one of the Chairman of the Board, the Chief 
Executive Officer, the President, any Vice President, the Chief Financial 
Officer, the Secretary or any Assistant Secretary of the Company and 
delivered to the Rights Agent; and such certificate shall be full 
authorization to the Rights Agent for any action taken or suffered in good 
faith by it under the provisions of this Agreement in reliance upon such 
certificate.

     (c)  The Rights Agent shall be liable hereunder to the Company and any 
other Person only for its own negligence, bad faith or willful misconduct; 
provided, however, that the Rights Agent shall not be liable for special, 
indirect, incidental or consequential loss or damage.

     (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.

                                      -26-

<PAGE>

     (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 Chief Executive Officer, the President, any Vice President, the 
Chief Financial Officer, the Secretary or any Assistant Secretary of the 
Company, and to apply to such officers for advice or instructions in 
connection with its duties, and it shall not be liable for any action taken 
or suffered by it in good faith in accordance with instructions of any such 
officer or for any delay in acting while waiting for those instructions.  Any 
application by the Rights Agent for written instructions from the Company 
may, at the option of the Rights Agent, set forth in writing any action 
proposed to be taken or omitted by the Rights Agent under this Rights 
Agreement and the date on and/or after which such action shall be taken or 
such omission shall be effective. The Rights Agent shall not be liable for 
any action taken by, or omission of, the Rights Agent in accordance with a 
proposal included in any such application on or after the date specified in 
such application (which date shall not be less than five (5) Business Days 
after the date any officer of the Company actually receives such application, 
unless any such officer shall have consented in writing to an earlier date) 
unless, prior to taking any such action (or the effective date in the case of 
an omission), the Rights Agent shall have received written instructions in 
response to such application specifying the action to be taken or omitted.

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

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

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

     (k)  If, with respect to any Rights Certificate surrendered to the 
Rights Agent for exercise or transfer, the certificate attached to the form 
of assignment or form of election to purchase, as the case may be, has either 
not been completed or indicates an affirmative response

                                      -27-

<PAGE>

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 either (a) a 
corporation organized and doing business under the laws of the United States 
or of any state of the United States, in good standing, which is authorized 
under such laws to exercise corporate trust or stockholder services powers 
and is subject to supervision or examination by federal or state authority 
and which has at the time of its appointment as Rights Agent a combined 
capital and surplus of at least $50 million or (b) an affliate of such a 
corporation.  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

                                      -28-

<PAGE>

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 or (ii) the Final Expiration 
Date, redeem all but not less than all the then outstanding Rights at a 
redemption price of $.01 per Right, appropriately adjusted to reflect any 
stock split, stock dividend or similar transaction occurring after the date 
hereof (such redemption price being herein referred to as the "Redemption 
Price") and the Company may, at its option, pay the Redemption Price either 
in Common Shares (based on the current per share market price thereof (as 
determined pursuant to Section 11(d) hereof) at the time of redemption) or 
cash; 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. 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 
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 the Board of 
Directors 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

                                      -30-

<PAGE>

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 that 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 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 
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 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

                                      -31-

<PAGE>


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 be given or made by the Rights Agent or by the holder of any Rights 
Certificate to or on the Company shall be sufficiently given or made if sent 
by first-class mail, postage prepaid, addressed (until another address is

the registry books of the Company.

     Section 27.    SUPPLEMENTS AND AMENDMENTS.  Prior to the Distribution 
Date, the Company may supplement or amend this Agreement in any respect 
without the approval of any holders of Rights and the Rights Agent shall, if 
the Company so directs, execute such supplement or amendment.  From and after 
the Distribution Date, the Company and the Rights Agent may from time to time 
supplement or amend this Agreement without the approval of any holders of 
Rights in order to (i) cure any ambiguity, (ii) correct or supplement any 
provision contained herein which may be defective or inconsistent with any 
other provisions herein, (iii) shorten or lengthen any time period hereunder 
(which lengthening or shortening, following the first occurrence of an event 
set forth in clauses (i) and (ii) of the proviso to Section 23(a) hereof, 
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

                                      -32-

<PAGE>

compliance with the terms of this Section 27, the Rights Agent shall execute 
such supplement or amendment.  Prior to the Distribution Date, the interests 
of the holders of Rights shall be deemed coincident with the interests of the 
holders of Common Shares.

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

     Section 29.    DETERMINATIONS AND ACTIONS BY THE BOARD OF DIRECTORS, 
ETC. For all purposes of this Agreement, any calculation of the number of 
Common Shares outstanding at any particular time, including for purposes of 
determining the particular percentage of such outstanding Common Shares of 
which any Person is the Beneficial Owner, shall be made in accordance with 
the last sentence of Rule 13d-3(d)(1)(i) of the General Rules and Regulations 
under the Exchange Act.  The Board of Directors of the Company (and, where 
specifically provided for herein, the Continuing 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

                                      -33-

<PAGE>

reinstated and shall not expire until the close of business on the tenth day 
following the date of such determination by the Board of Directors.

     Section 32.    GOVERNING LAW.  This Agreement and each Right and each 
Rights Certificate issued hereunder shall be deemed to be a contract made 
under the laws of the State of Delaware and for all purposes shall be 
governed by and construed in accordance with the laws of such State 
applicable to contracts to be made and performed entirely within such State.

     Section 33.    COUNTERPARTS.  This Agreement may be executed in any 
number of counterparts and each of such counterparts shall for all purposes 
be deemed to be an original, and all such counterparts shall together 
constitute but one and the same instrument.

     Section 34.    DESCRIPTIVE HEADINGS.  Descriptive headings of the 
several Sections of this Agreement are inserted for convenience only and 
shall not control or affect the meaning or construction of any of the 
provisions hereof.

     IN WITNESS WHEREOF, the parties hereto have caused this Preferred Shares 
Rights Agreement to be duly executed as of the day and year first above 
written.

Pursuant to Section 151 of the General Corporation Law of the State of 
Delaware

     We, Kathryn A. Tunstall and Michael W. Hall, the President and the 
Secretary, respectively, of Conceptus, Inc., a corporation organized and 
existing under the General Corporation Law of the State of Delaware, in 
accordance with the provisions of Section 103 thereof, DO HEREBY CERTIFY:

     That pursuant to the authority conferred upon the Board of Directors by 
the Certificate of Incorporation of the said Corporation, the said Board of 
Directors on February 27, 1997 adopted the following resolution creating a 
series of shares of Preferred Stock designated as Series A Participating 
Preferred Stock:

     "RESOLVED, that pursuant to the authority vested in the Board of 
Directors of the corporation by the Certificate of Incorporation, the Board 
of Directors does hereby provide for the issue of a series of Preferred 
Stock, $0.003 par value, of the Corporation, to be designated ""SERIES A

restrictions of the Series A Participating Preferred Stock are not stated and 
expressed in the Certificate of Incorporation, does hereby fix and herein 
state and express such designations, powers, preferences and relative and 
other special rights and the qualifications, limitations and restrictions 
thereof, as follows (all terms used herein which are defined in the 
Certificate of Incorporation shall be deemed to have the meanings provided 
therein):

     Section 1.     DESIGNATION AND AMOUNT.  The shares of such series shall 
be designated as "Series A Participating Preferred Stock", par value $0.003 
per share, and the number of shares constituting such series shall be thirty 
thousand (30,000).

     Section 2.     DIVIDENDS AND DISTRIBUTIONS.

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

<PAGE>

Preferred Stock shall be entitled to receive when, as and if declared by the 
Board of Directors out of funds legally available for the purpose, quarterly 
dividends payable in cash on the last day of March, June, September and 
December in each year (each such date being referred to herein as a 
"QUARTERLY DIVIDEND PAYMENT DATE"), commencing on the first Quarterly 
Dividend Payment Date after the first issuance of a share or fraction of a 
share of Series A Participating Preferred Stock, in an amount per share 
(rounded to the nearest cent) equal to, 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 February 27, 1997 (the 
"RIGHTS 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 and be cumulative 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 and be 
cumulative 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 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, 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

                                      -3-

<PAGE>

Series A Participating Preferred Stock and all such parity stock on which 
dividends are payable or in arrears in proportion to the total amounts to 
which the holders of all such shares are then entitled;

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

    (iv) purchase or otherwise acquire for consideration any shares of Series 
A Participating Preferred Stock, or any shares of stock ranking on a parity 
with the Series A Participating Preferred Stock, except in accordance with a 
purchase offer made in writing or by publication (as determined by the Board 
of Directors) to all holders of such shares upon such terms as the Board of 
Directors, after consideration of the respective annual dividend rates and 
other relative rights and preferences of the respective series and classes, 
shall determine in good faith will result in fair and equitable treatment 
among the respective series or classes.

     (C)  The Corporation shall not permit any subsidiary of the Corporation 
to purchase or otherwise acquire for consideration any shares of stock of the 
Corporation unless the Corporation could, under paragraph (A) of this Section 
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 an amount equal to accrued 
and unpaid dividends and distributions thereon, whether or not declared, to 
the date of such payment, plus an amount equal to the greater of (1) $1,000 
per share, provided that in the event the Corporation does not have 
sufficient assets, after payment of its liabilities and distribution to 
holders of Preferred Stock ranking prior to the Series A Participating 
Preferred Stock, available to permit payment in full of the $1,000 per share 
amount, the amount required to be paid under this Section 6(A)(1) shall, 
subject to Section 6(B) hereof, equal the value of the amount of available 
assets divided by the number of outstanding shares of Series A Participating 
Preferred Stock or (2) subject to the provisions for adjustment hereinafter 
set forth, 1,000 times the aggregate per share amount to be

                                      -4-

<PAGE>

distributed to the holders of Common Stock (the greater of (1) or (2), the 
"Series A Liquidation Preference").  In the event the Corporation shall at 
any time after the Rights 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 clause (2) of 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 that were 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)  In the event, however, that there are not sufficient assets 
available to permit payment in full of 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.

     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 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.


                                      -5-

<PAGE>

     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.''

                       consummated with a person who acquired shares pursuant
