INFORMATION REQUIRED IN REGISTRATION STATEMENT

Item 1. Description of Registrant's Securities to be Registered

    As of June 24, 1997, the Board of Directors of UroMed Corporation, a 
Massachusetts corporation (the "Company"), declared a dividend distribution 
of one preferred share purchase right (a "Right") for each outstanding share 
of common stock, no par value per share (the "Common Shares"), of the 
Company. The dividend is payable on July 9, 1997 (the "Record Date") to the 
stockholders of record on that date. Except as described below, each Right, 
when exercisable, entitles the registered holder to purchase from the Company 
one one-thousandth of a share of Series A Junior Participating Preferred 
Stock, par value $.01 per share (the "Preferred Shares"), of the Company at a 
price of $22.00 per one one-thousandth of a Preferred Share (the "Purchase 
Price"), subject to adjustment. The description and terms of the Rights are 
set forth in a Rights Agreement (the "Rights Agreement") between the Company 
and State Street Bank and Trust Company, as Rights Agent (the "Rights Agent").

    Initially, the Rights will be attached to all certificates representing 
Common Shares then outstanding, and no separate Rights certificates will be 
distributed. Until the earlier to occur of (i) 10 business days following a 
public announcement that a person or group of affiliated or associated 
persons (an "Acquiring Person", which does not include certain institutional 
investors which temporarily exceed the 15% threshold, and which does not 
include John G. Simon, the current President and Chief Executive Officer of 
the Company, and his associates so long as together they own less than 25% of 
the Common Shares) have acquired beneficial ownership of 15% or more of the 
outstanding Common Shares (the date of such an announcement being a "Shares 
Acquisition Date"), or (ii) 10 business days (or such later date as may be 
determined by action of the Board of Directors prior to such time as any 
Person becomes an Acquiring Person) following the commencement of, or 
announcement of an intention to make, a tender offer or exchange offer the 
consummation of which would result in the beneficial ownership by a person or 
group of 15% or more of such outstanding Common Shares (the earliest of such 
dates being called the "Distribution Date"), the Rights will be evidenced, 
with respect to any of the Common Share certificates outstanding as of the 
Record Date, by such Common Share certificate together with a copy of the 
Summary of Rights to be distributed to stockholders shortly after July 9, 
1997 (the "Summary of Rights").

    The Rights Agreement provides that, until the Distribution Date, the 
Rights will be transferred with and only with the Common Shares. Until the 
Distribution Date (or earlier redemption or expiration of the Rights), new 
Common Share certificates issued after the Record Date upon transfer or new 
issuance of Common Shares will contain a notation incorporating the Rights 
Agreement by reference. Until the Distribution Date (or earlier redemption or 
expiration of the Rights), the surrender for transfer of any certificates for 
Common Shares outstanding as of the


<PAGE>

                                       2

Record Date, even without such 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. As soon 
as practicable following the Distribution Date, separate certificates 
evidencing the Rights ("Rights Certificates") will be mailed to holders of 
record of the Common Shares as of the close of business on the Distribution 
Date, and the separate Rights Certificates alone will evidence the Rights.

     The Rights are not exercisable until the Distribution Date. The Rights 
will expire on July 9, 2007 (the "Final Expiration Date"), unless the Rights 
are earlier redeemed by the Company, as described below.

     The Purchase Price payable, and the number of Preferred Shares or other 
securities or property issuable, upon exercise of the Rights are subject to 
adjustment from time to time to prevent dilution (i) in the event of a stock 
dividend on, or a subdivision, combination or reclassification of, the 
Preferred Shares, (ii) upon the grant to holders of the Preferred Shares of 
certain rights or warrants to subscribe for or purchase Preferred Shares at a 
price, or securities convertible into Preferred Shares with a conversion 
price, less than the then current market price of the Preferred Shares or 
(iii) upon the distribution to holders of the Preferred Shares of evidences 
of indebtedness or assets (excluding regular periodic cash dividends paid out 
of earnings or retained earnings or dividends payable in Preferred Shares) or 
of subscription rights or warrants (other than those referred to above).

     The number of outstanding Rights and the number of one one-thousandths 
of a Preferred Share issuable upon exercise of each Right are also subject to 
adjustment in the event of a stock split of the Common Shares or a stock 
dividend on the Common Shares payable in Common Shares or subdivisions, 
consolidations or combinations of the Common Shares occurring, in any such 
case, prior to the Distribution Date.

     Preferred Shares purchasable upon exercise of the Rights will not be 
redeemable. Each Preferred Share will be entitled to a minimum preferential 
quarterly dividend payment of $1 per share but will be entitled to a 
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 minimum preferential liquidation payment of $10.00 per share 
but will be entitled to an aggregate payment of 1,000 times the payment made 
per Common Share. Each Preferred Share will have 1,000 votes, voting together 
with the Common Shares. Finally, in the event of any merger, consolidation or 
other transaction in which Common Shares are exchanged, each Preferred Share 
will be entitled to receive 1,000 times the amount received per Common Share. 
these rights are protected by customary antidilution provisions.

<PAGE>

                                       3

     Because of the nature of the Preferred Shares' dividend, liquidation and 
voting rights, the value of the one one-thousandth interest in a Preferred 
Share purchasable upon exercise of each Right is intended to approximate the 
value of one Common Share.

     In the event that, after the first date of public announcement by the 
Company or an Acquiring Person that an Acquiring Person has become such, the 
Company is involved in a merger or other business combination transaction in 
which the Common Shares are exchanged or changed, or 50% or more of the 
Company's consolidated assets or earning power are sold (in one transaction 
or a series of transactions), proper provision will be made so that each 
holder of a Right (other than an Acquiring Person) will thereafter have the 
right to receive, upon the exercise thereof at the then current exercise 
price of the Right, that number of shares of common stock of the acquiring 
company (or, in the event there is more than one acquiring company, the 
acquiring company receiving the greatest portion of the assets or earning 
power transferred) which at the time of such transaction would have a market 
value of two times the exercise price of the Right.

    In the event that (i) any person becomes an Acquiring person, (ii) an 
Acquiring Person engages in one or more "self-dealing" transactions as set 
forth in the Rights Agreement, or (iii) during such time as there is an 
Acquiring Person, there shall be a reclassification of securities or a 
recapitalization or reorganization of the Company or other transaction or 
series of transactions involving the Company which has the effect of 
increasing by more that 1% the proportionate share of the outstanding shares 
of any class of equity securities of the Company or any of its subsidiaries 
beneficially owned by the Acquiring Person, proper provision shall be made so 
that each holder of a Right, other than Rights benficially owned by any 
Acquiring Person, will thereafter have the right to receive upon exercise 
that number of Common Shares having a market value of two times the exercise 
price of the Right. Upon occurrence of any of the events described in the 
immediately preceding sentence, any Rights that are, or (under certain 
circumstances specified in the Rights Agreement) were beneficially owned by 
an Acquiring Person shall immediately become null and void. At any time after 
the occurrence of any such event and prior to the acquisition by any person 
or group of 50% or more of the outstanding Common Shares, the Continuing 
Directors (as defined below) may exchange the Rights (other than Rights owned 
by an Acquiring Person and certain related persons which have become void), 
in whole or in part, at an exchange ratio of one Common Share, or one 
one-thousandth of a Preferred Share (or of a share of a class or series of 
the Company's preferred stock having equivalent rights, preferences and 
privileges), per Right (subject to adjustment).

     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. No fractional preferred Shares will be issued (other than 
fractions which are

<PAGE>

                                       4

integral multiples of one one-thousandth of a Preferred Share, which may, at 
the election of the Company, be evidenced by depositary receipts) and in lieu 
thereof, an adjustment in cash will be made based on the market price of the 
Preferred Shares on the last trading day prior to the date of exercise.

    At any time prior to the earlier of (i) the tenth day after a Shares 
Aquisition Date, or (ii) the expiration of the Rights, the Board of Directors 
may redeem the Rights in whole, but not in part, at a price of $.001 per 
Right (the "Redemption Price"). Under certain circumstances set forth in the 
Rights Agreement, such a redemption would require the concurrence of the 
Company's "Continuing Directors", that is, any director who is not an 
Acquiring Person or an affiliate or associate of an Acquiring Person and who 
was in office prior to the date of the Rights Agreement or subsequently 
nominated by a majority of the Continuing Directors. Thereafter, the Rights 
may only be redeemed by the Continuing Directors in whole, but not in part, 
at the Redemption Price, (a) under certain circumstances described in the 
Rights Agreement involving a disposition of Common Shares by the Acquiring 
Person such that the Acquiring Person's common share ownership is reduced to 
10% or less, or (b) if such redemption is incidental to a merger or other 
business combination transaction or series of transactions involving the 
Company but not involving an Acquiring Person and satisfying certain other 
conditions. The redemption of the rights may be made effective at such time 
on such basis and with such conditions as the Board of Directors or the 
Continuing Directors, as the case may be, in their sole discretion may 
establish. Immediately upon any redemption of the Rights, the right to 
exercise the Rights will terminate and the only right of the holders of 
Rights will be to receive the Redemption Price.

    Other than those provisions relating to the principal economic terms of 
the Rights, any of the provisions of the Rights Agreement may be amended by 
the Board of Directors of the Company prior to the Distribution Date. After 
the Distribution Date, the provisions of the Rights Agreement may be amended 
by the Board (in certain circumstances, with the concurrence of the 
Continuing Directors) in order to cure any ambiguity, to make changes that 
do not adversely affect the interests of holders of Rights (excluding the 
interests of any Acquiring Person), or to shorten or lengthen any time 
period under the Rights Agreement; provided, however, that no amendment to 
adjust the time period governing redemption shall be made at such time as the 
Rights are not redeemable.

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

     Rights Agreement, dated as of June 26, 1997, between UroMed Corporation, 
a Massachusetts corporation (the "Company"), and State Street Bank and Trust 
Company, a Massachusetts Trust Company (the "Rights Agent").

     WHEREAS, the Board of Directors of the Company has authorized and 
declared a dividend distribution 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 on July 9, 1997 (the "Record Date"), 
each Right representing the right to purchase one one-thousandth of a 
Preferred Share (as hereinafter defined), upon the terms and subject to the 
conditions herein set forth, and in addition has authorized and directed the 
issuance of one Right 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);

     NOW, THEREFORE, in consideration of the premises and the mutual 
agreements herein set forth, the parties hereto 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 (as such term is 
hereinafter defined) who or which, together with all Affiliates and 
Associates (as such terms are hereinafter defined) of such Person, shall be 
the Beneficial Owner (as such term is hereinafter defined) of 15% or more of 
the Common Shares of the Company then outstanding or who was such a 
Beneficial Owner at any time after the date hereof, whether or not such 
Person continues to be the Beneficial Owner of 15% or more of the Common 
Shares then outstanding, but shall not include any Simon Investor and any 
Schedule 13G Investor, the Company, any Subsidiary (as such terms are 
hereinafter defined) of the Company, any employee benefit plan of the Company 
or any Subsidiary of the Company, or any entity holding securities of the 
Company organized, appointed or established by the Company or any Subsidiary 
for or pursuant to the terms of any such plan. Notwithstanding the foregoing, 
no Person shall become an "Acquiring Person" solely as the result of an 
acquisition of Common Shares by the Company which, by reducing the number of 
shares outstanding, increases the proportionate number of shares beneficially 
owned by such Person to 15% or more of the Common Shares of the Company then 
outstanding; provided, however, that if a Person shall become the Beneficial 
Owner of 15% or more of the Common Shares of the Company then outstanding by 
reason of share purchases by the Company and shall, after such share 
purchases by the Company, become the Beneficial Owner of any additional 
Common Shares of the Company, then such Person shall be deemed to be an 
"Acquiring Person".  

<PAGE>

                                    -2-

          (b)  "Adjusted Shares" shall have the meaning set forth in Section 
11(a).

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

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

              (i) that such Person or any of such Person's
    Affiliates or Associates beneficially owns, directly or indirectly;

             (ii) that such Person or any of such Person's Affiliates or 
    Associates, directly or indirectly, has the right to acquire (whether 
    such right is exercisable immediately or only after the passage of time) 
    pursuant to any agreement, arrangement or understanding (whether or not 
    in writing) or upon the exercise of conversion rights, exchange rights, 
    rights (other than the Rights), warrants or options, or otherwise; 
    provided, however, that a Person shall not be deemed the "Beneficial 
    Owner" of, or to "beneficially own", (A) securities tendered pursuant to 
    a tender or exchange offer made by such Person or any of such Person's 
    Affiliates or Associates until such tendered securities are accepted for 
    payment, purchase or exchange, or (B) securities issuable upon exercise 
    of Rights at any time prior to the occurrence of a Triggering Event, or 
    (C) securities issuable upon exercise of Rights from and after the 
    occurrence of a Triggering Event if such Rights were acquired by such 
    Person or any of such Person's Affiliates or Associates prior to the 
    Distribution Date or pursuant to Section 3(a) or Section 23 hereof (the 
    "Original Rights") or pursuant to Section 11(i) hereof in connection 
    with an adjustment made with respect to any Original Rights;
    
            (iii) that such Person or any of such Person's Affiliates or 
    Associates, directly or indirectly, has the right to vote or dispose of 
    or has "beneficial ownership" of (as determined pursuant to Rule 13d-3 
    of the General Rules and Regulations under the Exchange Act), including 
    without limitation pursuant to any agreement, arrangement or 
    understanding, whether or not in writing; provided, however, that a 
    Person shall not be deemed the "Beneficial Owner" of, or to 
    "beneficially own", any security under this subparagraph (iii) as a

               (y)  the Rights shall be evidenced (subject to the 
    provisions of Section 3(b) hereof) by the certificates for Common Shares 
    registered in the names of the holders thereof (which certificates shall 
    also be deemed to be certificates for Rights) and not by separate 
    certificates; and 

               (z)  the Rights (and the right to receive certificates 
    therefor) will be transferable only in connection with the transfer of 
    the underlying Common Shares.  As soon as practicable after the 
    Distribution Date, the Company shall prepare and execute, the Rights 
    Agent shall countersign, and the Company shall send or cause to be sent 
    (and the Rights Agent shall, if requested, send) by first-class, 
    insured, 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 certificate for 
    Rights, in substantially the form of Exhibit B hereto (the "Rights 
    Certificates"), evidencing one Right for each Common Share so held.  As 
    of and after the Distribution Date, the Rights shall be evidenced solely 
    by such Rights Certificates.

          (b)  On the Record Date, or as soon as practicable thereafter, the 
Company shall send a copy of a Summary of Rights to Purchase Preferred 
Shares, in substantially the form of Exhibit C hereto (the "Summary of 
Rights"), by first-class, postage-prepaid mail, to each record holder of

of such holder shown on the records of the Company.  With respect to 
certificates for Common Shares outstanding as of the Record Date, until the 
Distribution Date (or earlier redemption, expiration or termination of the 
Rights), the Rights shall be evidenced by such certificates for Common Shares 
registered in the names of the holders thereof together with a copy of the 
Summary of Rights attached thereto and the registered holders of the Common 
Shares shall also be the registered holders of the associated Rights.  Until 
the Distribution Date (or earlier redemption, expiration or termination of 
the Rights), the surrender for transfer of any certificate for Common Shares 
outstanding on the Record Date, even without a copy of the Summary of Rights 
attached thereto, shall also constitute the transfer of the Rights associated 
with the Common Shares represented by such certificate.

          (c)  Certificates issued for Common Shares (including, without 
limitation, certificates issued upon transfer or exchange of Common Shares) 
after the Record Date but prior to the earlier of the Distribution Date or 
the Expiration Date

<PAGE>

                                    -8-

shall be deemed also to be certificates for Rights and shall have impressed 
on, printed on, written on or otherwise affixed to them the following legend:

    "This certificate also evidences and entitles the holder hereof to 
    certain rights as set forth in a Rights Agreement between UroMed 
    Corporation and State Street Bank and Trust Company, dated as of June 
    26, 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 UroMed Corporation.  Under certain 
    circumstances, as set forth in the Rights Agreement, such Rights may be 
    redeemed, may expire, or may be evidenced by separate certificates and 
    no longer be evidenced by this certificate.  UroMed Corporation will 
    mail to the holder of this certificate a copy of the Rights Agreement 
    without charge after receipt of a written request therefor.  As 
    described in the Rights Agreement, under certain circumstances, Rights 
    issued to Acquiring Persons (as defined in the Rights Agreement) or 
    certain related persons and any subsequent holder of such Rights may 
    become null and void."

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

     Section 4.  Form of Rights Certificates.

          (a)  The Rights Certificates (and the forms of election to purchase 
shares and of assignment to be printed on the reverse thereof) shall each be 
substantially the same as 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 23 hereof, the Rights Certificates 
shall entitle the holders thereof to purchase such number of one 
one-thousands of a Preferred Share as shall be set forth therein at the price 
per one one-thousandth of a Preferred Share set forth therein (the "Purchase 
Price"), but the number of such one one-thousands of a Preferred Share and 
the Purchase Price shall be subject to adjustment as provided herein.

          (b)  Any Rights Certificate issued pursuant to Section 3(a) or 
Section 23 hereof that represents Rights that the Company knows are 
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 oral or 
written plan, agreement, arrangement or understanding regarding the 
transferred Rights or (B) a transfer which a majority of the Continuing 
Directors of the Company then in office determine is part of any oral or 
written plan, agreement, arrangement or understanding that has as a primary 
purpose or effect the 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 Certificate were issued to a Person who 
    was or became an Acquiring Person or an Affiliate or an Associate of an 
    Acquiring Person.  Accordingly, this Certificate and the Rights 
    represented hereby may be or become null and void in the circumstances 
    specified in Section 7(e) of the Rights Agreement."

     The provisions of Section 7(e) of this Rights Agreement shall be 
operative whether or not the foregoing legend is contained on any such Rights 
Certificate.

     Section 5.  Countersignature and Registration.  The Rights Certificates 
shall be executed on behalf of the Company by the President, any Executive 
Vice President, or the Treasurer of the Company, either manually or by 
facsimile signature, shall have affixed thereto the Company's seal or a 
facsimile thereof, and shall be attested by the Clerk or an Assistant Clerk 
of the Company, either manually or by facsimile signature.  The Rights 
Certificates shall be manually countersigned by the Rights Agent and shall 
not be valid for any purpose unless countersigned.  In case any officer of 
the Company who shall have signed any of the Rights Certificates shall cease 
to be such officer of the Company before countersignature by the Rights Agent 
and issuance and delivery by the Company, such Rights Certificates, 
nevertheless, may be countersigned by the Rights Agent and issued and 
delivered by the Company with the same force and effect as though the person 
who signed such Rights Certificates had not ceased to be such officer of the 
Company; and any Rights Certificate may be signed on behalf of the Company by 
any person who, at the actual date of the execution of such Rights 
Certificate, shall be a proper officer of the 

<PAGE>

                                   -10-

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.

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

     Section 6.  Transfer, Split-Up, Combination and Exchange of Rights 
Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates.  
Subject to the provisions of Sections 4(b), 7(e) and 15 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 one-thousandths of a Preferred Share 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.  Thereupon the Rights Agent shall countersign and deliver to the 
Person entitled thereto a Rights Certificate or Rights Certificates, as the 
case may be, as so requested.  The Company may require payment of a sum 
sufficient to cover any tax or governmental charge that may be imposed in 
connection with any transfer, split-up, combination or exchange of Rights 
Certificates.

     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 shall execute and deliver 
a new Rights Certificate of like tenor to the Rights Agent for delivery to 
the registered holder in lieu of the Rights Certificate so lost, stolen, 
destroyed or mutilated.

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

          (a)  Subject to subsection (e), the registered holder of any Rights 
Certificate may exercise the Rights evidenced thereby (except as otherwise 
provided herein) in whole or in part at any time after the Distribution Date 
upon surrender of

<PAGE>

                                   -11-

the Rights Certificate, with the form of election to purchase on the reverse 
side thereof duly executed, to the Rights Agent at the office of the Rights 
Agent designated for such purpose, together with payment of the Purchase 
Price for each one one-thousandth of a Preferred Share (or such other number 
of Preferred Shares or other securities) as to which the Rights are 
exercised, at or prior to the earliest of (i) the close of business on July 
9, 2007 (the "Final Expiration Date"), (ii) the time at which the Rights are 
redeemed as provided in Section 24 hereof (the "Redemption Date"), or (iii) 
the time at which such Rights are exchanged as provided in Section 25 hereof 
(such earliest time being herein referred to as the "Expiration Date").

          (b)  The Purchase Price for each one one-thousandth of a Preferred 
Share pursuant to the exercise of a Right shall initially be $22.00, shall be 
subject to adjustment from time to time as provided in Sections 11 and 13 
hereof and shall be payable in lawful money of the United States of America 
in accordance with paragraph (c) below.

          (c)  Upon receipt of a Rights Certificate representing exercisable 
Rights, with the appropriate form of election to purchase duly executed, 
accompanied by payment of the Purchase Price for the shares to be purchased 
and an amount equal to any applicable transfer tax required to be paid by the 
holder of such Rights Certificate in accordance with Section 9 hereof in cash 
or by certified check, cashier's check or money order or bank draft paid or 
payable to the order of the Company, the Rights Agent shall thereupon 
promptly (i) (A) requisition from any transfer agent of the Preferred Shares 
(or make available, if the Rights Agent is the transfer agent) certificates 
for the number of Preferred Shares to be purchased and the Company hereby 
irrevocably authorizes its transfer agent to comply with all such requests, 
or (B) if the Company, in its sole discretion, shall have elected to deposit 
the Preferred Shares issuable upon conversion of the Rights hereunder into a 
depositary, requisition from the depositary agent depositary receipts 
representing such number of one one-thousandths of a Preferred Share as are to 
be purchased (in which case certificates for the Preferred Shares represented 
by such receipts shall be deposited by the transfer agent with the depositary 
agent) and the Company shall direct the depositary agent to comply with such 
request, (ii) when appropriate, requisition from the Company the amount of 
cash, if any, to be paid in lieu of issuance of fractional shares in 
accordance with Section 15 hereof, (iii) promptly after receipt of such 
certificates or depositary receipts, cause the same to be delivered to or 
upon the order of the registered holder of such Rights Certificate, 
registered in such name or names as may be designated by such holder, and 
(iv) when appropriate, after receipt, promptly deliver such cash to or upon 
the order of the registered holder of such Rights Certificate.  In the event 
that the Company is obligated to issue other securities of the Company 
pursuant to Section 11(a), the Company shall make all arrangements necessary 
so that such other securities are available for distribution by the Rights 
Agent, if and when appropriate.

<PAGE>

                                   -12-

          (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 duly authorized assigns, subject to the provisions of 
Section 15 hereof.

          (e)  Notwithstanding anything in this Agreement to the contrary, 
from and after the first occurrence of a Section 11(a)(ii) Event, any 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 oral or 
written plan, agreement, arrangement or understanding regarding the 
transferred Rights or (B) a transfer which a majority of the Continuing 
Directors of the Company then in office determine is part of any oral or 
written plan, agreement, arrangement or understanding that has as a primary 
purpose or effect the avoidance of this Section 7(e), 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 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) are complied with, but 
shall have no liability to any holder of Rights Certificates or other Person 
as a result of its failure to make any determinations hereunder with respect 
to an Acquiring Person or the Affiliates, Associates or transferees of an 
Acquiring Person.

          (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 the certificate 
contained in the form of election to purchase set forth on the reverse side 
of the Rights Certificate surrendered for such exercise shall have been 
properly completed and duly executed by the registered holder thereof and the 
Company shall have been provided with 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 cancelled 
form, or, if surrendered to the Rights Agent, shall be cancelled by it, and 
no Rights Certificates shall be issued in 

<PAGE>

                                   -13-

lieu thereof except as expressly permitted by any of the provisions of this 
Rights Agreement.  The Company shall deliver to the Rights Agent for 
cancellation and retirement, and the Rights Agent shall 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 cancelled 
Rights Certificates to the Company, or shall, at the written request of the 
Company, destroy such cancelled 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 shall cause to be 
reserved and kept available out of its authorized and unissued Preferred 
Shares or any Preferred Shares held in its treasury, the number of Preferred 
Shares (or other securities) that will be sufficient to permit the exercise 
in full of all outstanding Rights in accordance with Section 7 of this 
Agreement.

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

          (c)  The Company further covenants and agrees that it shall pay 
when due and payable any and all federal and state transfer taxes and charges 
which may be payable in respect of the issuance or delivery of the Rights 
Certificates or of any Preferred Shares or other securities upon the exercise 
of Rights.  The Company shall not, however, be required to pay any transfer 
tax which may be payable in respect of any transfer or delivery of Rights 
Certificates to a Person other than, or the issuance or delivery of 
certificates or depositary receipts for the Preferred Shares or other 
securities in a name other than that of, the registered holder of the Rights 
Certificate evidencing Rights surrendered for exercise or to issue or to 
deliver any certificates or depositary receipts for Preferred Shares or other 
securities 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 
reasonable satisfaction that no such tax is due.

          (d)  If then required by applicable law, the Company shall use its 
best efforts to (i) file, as soon as practicable following the Distribution 
Date, 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

<PAGE>

                                   -14-

 Act and the rules and regulations thereunder) until the earlier of (A) the 
date as of which the Rights are no longer exercisable for such securities or 
(B) the Expiration Date. The Company will also take such action as may be 
appropriate under the securities laws of the various states.  The Company may 
temporarily suspend the exercisability of the Rights in order to prepare and 
file such registration statement.  Upon any such suspension, the Company 
shall issue a public announcement stating that the exercisability of the 
Rights has been temporarily suspended.  The Company shall thereafter issue a 
public announcement at such time as the suspension is no longer in effect.  
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.

          (e)  If at the time the Rights become exercisable, the then 
outstanding Common Shares are listed on any national or regional securities 
exchange or are quoted on the National Association of Securities Dealers, 
Inc. Automated Quotations System ("NASDAQ") or any successor thereto or other 
comparable quotation system, the Company shall use its best efforts to cause, 
from and after such time as the Rights become exercisable, all Preferred 
Shares (and, following the occurrence of a Triggering Event, other 
securities) reserved for issuance upon such exercise to be quoted on such 
system or listed on such exchange, as the case may be.

     Section 10.  Preferred Shares Record Date.  Each Person in whose name 
any certificate for Preferred Shares (or other securities) is issued upon the 
exercise of Rights shall for all purposes be deemed to have become the holder 
of record of the 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 
(and any applicable transfer taxes) was made; provided, however, that if the 
date of such surrender and payment is a date upon which the transfer books of 
the Company for such Preferred Shares (or other securities) are closed, such 
Person shall be deemed to have become the record holder of such shares on, 
and such certificate shall be dated, the next succeeding Business Day on 
which the transfer books of the Company for such Preferred Shares (or other 
securities) 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 
shareholder of the Company with respect to shares for which the Rights shall 
be exercisable, including, without limitation, the right to vote, to receive 
dividends or other distributions or to exercise any 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 and Kind of Shares or 
Number of Rights.  The Purchase Price, the number and kind of shares covered 
by each Right and the number of Rights outstanding are subject to adjustment 
from time to time as provided in this Section 11.

<PAGE>

                                   -15-

              (a)  (i)  In the event the Company shall at any time
    after the date of this Agreement (A) declare a dividend on
    the Preferred Shares payable in Preferred Shares,
    (B) subdivide the outstanding Preferred Shares, (C) combine
    the outstanding Preferred Shares 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), except as otherwise
    provided in this Section 11(a) and in Section 7(e), 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, and the number and kind of
    shares of capital stock issuable on such date, shall be
    proportionately adjusted so that the holder of any Right
    exercised after such time shall be entitled to receive the
    aggregate number and kind of shares of capital stock which,
    if such Right had been exercised immediately prior to such
    date and at a time when the transfer books of the Company
    for the Preferred Shares were open, such holder would have
    owned upon such exercise and been entitled to receive by
    virtue of such dividend, subdivision, combination or
    reclassification; provided, however, that in no event shall
    the consideration to be paid upon the exercise of one Right
    be less than the aggregate par value of the shares of
    capital stock of the Company issuable upon exercise of one
    Right.  If an event occurs which would require an adjustment
    under both this Section 11(a)(i) and Section 11(a)(ii), the
    adjustment provided for in this Section 11(a)(i) shall be in
    addition to, and shall be made prior to, any adjustment
    required pursuant to Section 11(a)(ii).

                  (ii) Subject to Section 25 of this Agreement, in the event: 

                      (A)  any Acquiring Person or any Associate or 
          Affiliate of any Acquiring Person, at any time after the Shares 
          Acquisition Date, directly or indirectly:

                          (1)  shall merge into the Company or
          otherwise combine with the Company and the Company shall 
          be the continuing or surviving corporation of such merger 
          or combination and the Common Shares of the Company or other
          equity securities of the Company shall remain outstanding;

                          (2)  shall, in one transaction or a 
          series of transactions, transfer any assets to the Company or 
          to any of its Subsidiaries in exchange (in whole or in part) 
          for Common Shares, for shares of other equity securities of 
          the Company, or for securities exercisable for or convertible 
          into shares of equity securities of the Company (Common Shares 
          or otherwise) or

<PAGE>

                                   -16-

           otherwise obtain from the Company, with or without 
           consideration, any additional shares of such equity securities 
           or securities exercisable for or convertible into shares of 
           such equity securities (other than pursuant to a pro rata 
           distribution to all holders of Common Shares);

                          (3)  shall sell, purchase, lease, 
           exchange, mortgage, pledge, transfer or otherwise acquire or 
           dispose of assets in one transaction or a series of 
           transactions, to, from or with (as the case may be) the 
           Company or any of its Subsidiaries, on terms and conditions 
           less favorable to the Company than the Company would be able 
           to obtain in arm's-length negotiation with an unaffiliated 
           third party, other than pursuant to a Section 13 Event;

                          (4)  shall sell, purchase, lease, 
           exchange, mortgage, pledge, transfer or otherwise acquire or 
           dispose of assets having an aggregate fair market value of 
           more than $5,000,000 in one transaction or a series of 
           transactions, to, from or with (as the case may be) the 
           Company or any of the Company's Subsidiaries (other than 
           incidental to the lines of business, if any, engaged in as of 
           the date hereof between the Company and such Acquiring Person 
           or Associate or Affiliate), other than pursuant to a Section 
           13 Event;
 
                          (5)  shall receive any compensation 
           from the Company or any of the Company's Subsidiaries other 
           than compensation for full-time employment as a regular 
           employee at rates in accordance with the Company's (or its 
           Subsidiaries') past practices; or

                          (6)  shall receive the benefit, 
           directly or indirectly (except proportionately as a 
           stockholder and except if resulting from a requirement of law 
           or governmental regulation), of any loans (other than in the 
           ordinary course of business), advances, guarantees, pledges or 
           other financial assistance or any tax credits or other tax 
           advantage provided by the Company or any of its Subsidiaries; 
           or 

                      (B)  any Person (other than the Company, any 
          Subsidiary of the Company, any employee benefit plan of the Company
          or any of its Subsidiaries or any entity holding securities of the
          Company organized, appointed or established by the Company or any of
          its Subsidiaries for or pursuant to the terms of any such plan),

<PAGE>

                                    -17-

    alone or together with its Affiliates and Associates, shall 
    become an Acquiring Person; or 

                      (C)  during such time as there is an       
          Acquiring Person, there shall be any reclassification of securities 
          (including any reverse stock split), or recapitalization or 
          reorganization of the Company or other transaction or series of 
          transactions involving the Company which has the effect, directly or 
          indirectly, of increasing by more than 1% the proportionate share of
          the outstanding shares of any class of equity securities of the 
          Company or any of its Subsidiaries beneficially owned by any 
          Acquiring Person or any Affiliate or Associate thereof;

then, and in each such case, proper provision shall promptly be made so that, 
following the Distribution Date, each holder of a Right, except as provided 
in Section 7(e) hereof, shall have a right to receive, upon exercise thereof 
at a price equal to the then current Purchase Price multiplied by the number 
of one one-thousandths of a Preferred Share for which a Right is then 
exercisable, in accordance with the terms of this Agreement and in lieu of 
Preferred Shares, such number of Common Shares of the Company as shall equal 
the result obtained by (x) multiplying the then current Purchase Price by the 
number of one one-thousandths of a Preferred Share for which a Right was 
exercisable immediately prior to the first occurrence of a Section 11(a)(ii) 
Event, and (y) dividing that product (which, following such first occurrence, 
shall thereafter be referred to as the "Purchase Price" for each Right and 
for all purposes of this Agreement) by 50% of the then current per share 
market price of the Company's Common Shares (determined pursuant to Section 
11(d) hereof) on the date of such first occurrence (such number of shares, 
the "Adjustment Shares"); provided, however, that if the transaction that 
would otherwise give rise to the foregoing adjustment is also subject to the 
provisions of Section 13 hereof, then only the provisions of Section 13 
hereof shall apply and no adjustment shall be made pursuant to this Section 
11(a)(ii).

            (iii) In the event that the number of Common Shares that are 
    authorized by the Company's Restated Articles of Organization, 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 in accordance with the foregoing subparagraph (ii) of this 
    Section 11(a), the Company shall:

                    (A)  determine the excess of the value   of the 
       Adjustment Shares issuable upon the exercise of   a Right (the "Current 
       Value") over the Purchase Price    (such excess, the "Spread"); and

<PAGE>

                                   -18-

                    (B)  with respect to each Right, make adequate 
       provision to substitute for the Adjustment Shares, upon payment of the 
       applicable Purchase Price:

                         (1)  cash;

                         (2)  a reduction in the Purchase Price;

                         (3)  Common Shares of the same or a different
       class or other equity securities of the Company (including, without
       limitation, preferred shares or units of preferred shares that at least
       two thirds of the Continuing Directors in office at the time have deemed
       (based, among other things, on the dividend and liquidation rights of
       such preferred shares) to have substantially the same economic value as
       Common Shares (such preferred shares, hereinafter referred to as "common
       shares equivalents"));

                         (4)  debt securities of the Company;

                         (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 at least two thirds of the Continuing 
       Directors in office at the time after considering the advice of a 
       competent investment banking firm selected by the Board of Directors of
       the Company; 

       provided, however, if the Company shall have not 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 Section 11(a)(ii) 
       Event and (y) the date on which the Company's right of redemption 
       pursuant to Section 24(b) 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), 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 Rights, 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

<PAGE>

                                   -19-

       stockholder approval for the authorization of such additional shares 
       (such period, as it may be extended, the "Substitution Period").  To the 
       extent that the Company determines that some action need be taken 
       pursuant to the first and/or second sentences of this Section 
       11(a)(iii), the Company shall provide, subject to Section 7(e) hereof, 
       that such action shall apply uniformly to all outstanding Rights, and 
       may suspend the exercisability of the Rights until the expiration of the 
       Substitution Period in order to seek any authorization of additional 
       shares and/or to decide the appropriate form of distribution to be made 
       pursuant to such first sentence and to determine the value thereof.  The 
       Company shall make a public announcement when the exercisability of the 
       Rights has been temporarily suspended, and again when such suspension is 
       no longer in effect.  For purposes of this Section 11(a)(iii), the value 
       of the Common Shares shall be the current market price (as determined 
       pursuant to Section 11(d) hereof) per Common Share on the Section 
       11(a)(ii) Trigger Date and the value of any "common share equivalent" 
       shall be deemed to have the same value as the Common Shares on such date.

          (b)  If the Company shall fix a record date for the issuance of 
rights, options or warrants to all holders of Preferred Shares entitling them 
(for a period expiring within 45 calendar days after such record date) to 
subscribe for or purchase Preferred Shares (or shares having the same or more 
favorable rights, privileges and preferences as the Preferred Shares 
("equivalent preferred shares")) or securities convertible into Preferred 
Shares or equivalent preferred shares at a price per Preferred Share or 
equivalent preferred share (or having a conversion price per share, if a 
security convertible into Preferred Shares or equivalent preferred shares) 
less than the then current per share market price of the Preferred Shares (as 
defined in Section 11(d)) on such record date, 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 Preferred Shares outstanding on 
such record date plus the number of Preferred Shares which the aggregate 
offering price of the total number of Preferred Shares and/or equivalent 
preferred shares 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 
Preferred Shares outstanding on such record date plus the number of 
additional Preferred Shares and/or equivalent preferred shares to be offered 
for subscription or purchase (or into which the convertible securities so to 
be offered are initially convertible); provided, however, that in no event 
shall the consideration to be paid upon the exercise of one Right be less 
than the aggregate par value of the shares of capital stock of the Company 
issuable upon exercise of one Right.  In case such subscription price may be 
paid in a consideration part or all of which shall be in a form other than 
cash, the value of such consideration shall be as determined in good 

<PAGE>

                                   -20-

faith by the Board of Directors of the Company, whose determination shall be 
described in a statement filed with the Rights Agent.  Preferred 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)  If the Company shall fix a record date for the making of a 
distribution to all holders of the Preferred Shares (including any such 
distribution made in connection with a consolidation or merger in which the 
Company is the continuing or surviving corporation) of evidences of 
indebtedness, cash or assets (other than a regular quarterly cash dividend or 
a dividend payable in Preferred Shares) or subscription rights or warrants 
(excluding those referred to in Section 11(b) hereof), 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 then current per share market price of 
the Preferred Shares 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 assets, cash or evidences of indebtedness so to be 
distributed or of such subscription rights or warrants applicable to one 
Preferred Share and the denominator of which shall be such current per share 
market price of the Preferred Shares; 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 to 
be issued upon exercise of one Right.  Such adjustments shall be made 
successively whenever such a record date is fixed; and in the event that such 
distribution is not so made, the Purchase Price shall again be adjusted to be 
the Purchase Price which would then be in effect if such record date had not 
been fixed.

              (d)  (i)  For the purpose of any computation hereunder,
       other than computations made pursuant to Section 11(a)(iii)
       hereof, the "current per share market price" of any security
       (a "Security" for the purpose of this Section 11(d)(i)) on
       any date shall be deemed to be the average of the daily
       closing prices per share of such Security for the 30
       consecutive Trading Days (as such term is hereinafter
       defined) immediately prior to such date; provided, however,
       that in the event that the current per share market price of
       the Security is determined during a period following the
       announcement by the issuer of such Security of (A) a
       dividend or distribution on such Security payable in shares
       of such Security or securities convertible into such shares,
       or (B) any subdivision, combination or reclassification of
       such Security and prior to the expiration of 30 Trading Days
       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 

<PAGE>

                                   -21-

       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 quoted price or, if not so 
       quoted, the average of the high bid and low asked prices in the 
       over-the-counter market, as reported by NASDAQ or such other system then 
       in use, or, if on any such date the Security is not quoted by any such 
       organization, the average of the closing bid and asked prices as 
       furnished by a professional market maker making a market in the Security 
       selected by the Board of Directors of the Company.  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.

          (ii) For the purpose of any computation hereunder, the 
       "current per share market price" of the Preferred Shares shall be 
       determined in accordance with the method set forth in Section 11(d)(i).  
       If the Preferred Shares are not publicly traded, the "current per share 
       market price" of the Preferred Shares shall be conclusively deemed to be 
       the current per share market price of the Common Shares as determined 
       pursuant to Section 11(d)(i) (appropriately adjusted to reflect any 
       stock split, stock dividend or similar transaction occurring after the 
       date hereof), multiplied by one thousand.  If neither the Common Shares 
       nor the Preferred Shares are 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.

          (e)  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 one 
one-millionth of a Preferred Share or one ten-thousandth of any other share 
or security as the case may be. Notwithstanding the first sentence of this 
Section 11(e), any adjustment required by this Section 11 shall 

<PAGE>

                                    -22-

be made no later than the earlier of (i) three 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) 
hereof, the holder of any Right thereafter exercised shall become entitled to 
receive any shares of capital stock of the Company other than Preferred 
Shares, thereafter the number of such other shares so receivable upon 
exercise of any Right shall be subject to adjustment from time to time in a 
manner and on terms as nearly equivalent as practicable to the provisions 
with respect to the Preferred Shares contained in Section 11(a) through (c), 
(e), (h) through (k) and (m) and the provisions of Sections 7, 9, 10, 13, 14 
and 15 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 one-thousandth 
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 Sections 11(b) and (c), each Right 
outstanding immediately prior to the making of such adjustment shall 
thereafter evidence the right to purchase, at the adjusted Purchase Price, 
that number of one one-thousandths of a Preferred Share (calculated to the 
nearest one one-millionth of a Preferred Share) obtained by (i) multiplying 
(x) the number of one one-thousandths of a share covered by a Right immediately
prior to this adjustment by (y) the Purchase Price in effect immediately 
prior to such adjustment of the Purchase Price and (ii) dividing the product 
so obtained by the Purchase Price in effect immediately after such adjustment 
of the Purchase Price.

          (i)  The Company may elect on or after the date of any adjustment 
of the Purchase Price to adjust the number of Rights, in substitution for any 
adjustment in the number of one one-thousandths of a Preferred Share 
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 one-thousandths of a Preferred Share for which a Right was 
exercisable immediately prior to such adjustment.  Each Right held of record 
prior to such adjustment of the number of Rights shall become that number of 
Rights (calculated to the nearest one 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 

<PAGE>

                                   -23-

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 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 15 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 one one-thousandths of a Preferred Share issuable upon the 
exercise of the Rights, the Rights Certificates theretofore and thereafter 
issued may continue to express the Purchase Price and the number of one 
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 one one-thousandth of the then par value, 
if any, of the Preferred Shares 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 
fully paid and nonassessable Preferred Shares at such adjusted Purchase Price.

          (l)  In any case in which this Section 11 shall require that an 
adjustment in the Purchase Price be made effective as of a record date for a 
specified event, the Company may elect to defer until the occurrence of such 
event the issuing to the holder of any Right exercised after such record date 
of the Preferred Shares and other capital stock or securities of the Company, 
if any, issuable upon such exercise over and above the Preferred Shares 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 upon the occurrence of the event requiring 
such adjustment.

          (m)  Anything in this Section 11 to the contrary notwithstanding, 
the Company shall be entitled to make such reductions in the Purchase Price, 
in addition

<PAGE>

                                    -24-

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 consolidation or subdivision of the Preferred Shares, issuance 
wholly for cash of any Preferred Shares at less than the current market 
price, issuance wholly for cash of Preferred Shares or securities which by 
their terms are convertible into or exchangeable for Preferred Shares, stock 
dividends or issuance of rights, options or warrants referred to hereinabove 
in this Section 11, hereafter made by the Company to holders of its Preferred 
Shares shall not be taxable to such stockholders.

          (n)  Anything in this Agreement to the contrary notwithstanding, in 
the event that the Company shall at any time after the date of this Agreement 
and prior to the Distribution Date (i) declare a dividend on the outstanding 
Common Shares payable in Common Shares, (ii) subdivide the outstanding Common 
Shares, (iii) combine the outstanding Common Shares into a smaller number of 
shares or (iv) issue any of its shares of capital stock in a reclassification 
of the outstanding Common Shares (including any such reclassification in 
connection with a consolidation or merger in which the Company is the 
continuing or surviving entity), then in any such case, (A) the number of 
Rights associated with each Common Share or other such shares then 
outstanding, or issued or delivered thereafter but prior to the Distribution 
Date, shall be proportionately adjusted so that the number of Rights 
thereafter associated with each Common Share or other such shares following 
any such event shall equal the result obtained by multiplying the number of 
Rights associated with each Common Share immediately prior to such event by a 
fraction the numerator of which shall be the total number of Common Shares 
outstanding immediately prior to the occurrence of the event and the 
denominator of which shall be the total number of Common Shares outstanding 
immediately following the occurrence of such event, and (B) each Common Share 
outstanding immediately after such event shall have issued with respect to it 
that number of Rights (which may be represented by the certificate 
representing the underlying Common Shares in accordance with Section 3) which 
each Common Share outstanding immediately prior to such event had issued with 
respect to it.  The adjustments provided for in this Section 11(n) shall be 
made successively whenever such a dividend is declared or paid or such a 
subdivision, combination or reclassification is effected.

     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 Common Shares or the Preferred Shares a copy of such certificate and (c) 
mail a brief summary thereof to each holder of a Rights Certificate (or, if 
prior to the Distribution Date, to each holder of a certificate representing 
Common Shares) in accordance with Section 27 hereof.  The Rights Agent may 
rely on such certificate without further inquiry and may assume that no

<PAGE>

                                   -25-

such adjustment has been made unless and until it shall have received such 
certificate.

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

          (a)  In the event that, following the Shares Acquisition Date, 
directly or indirectly:

          (x)  the Company shall consolidate with, or merge with and 
    into, any other Person (other than a Subsidiary of the Company in a 
    transaction that complies with Section 14(b) hereof), and the Company 
    shall not be the continuing or surviving corporation of such 
    consolidation or merger;

          (y)  any Person (other than a Subsidiary of the Company in a 
    transaction that complies with Section 14(b) 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 merger and, in 
    connection with such merger, all or part of the Common Shares shall be 
    changed into or exchanged for stock or other securities of any other 
    Person (or the Company) or cash or any other property; or

          (z)  the Company shall sell or otherwise transfer (or one or 
    more of its Subsidiaries shall sell or otherwise transfer), in one or 
    more transactions, assets or earning power aggregating 50% or more of 
    the assets or earning power of the Company and its Subsidiaries (taken 
    as a whole) to any Person (other than to the Company or one or more of 
    its Subsidiaries in one or more transactions, each of which complies 
    with Section 14(b) hereof), then, and in each such case, proper 
    provision shall be made so that:

         (i)  following the Distribution Date, each holder of a Right, 
   subject to Section 7(e), shall have the right to receive, upon the 
   exercise thereof at the then current Purchase Price in accordance with 
   the terms of this Agreement, such number of freely tradeable Common 
   Shares of the Principal Party (as hereinafter defined), free and clear 
   of liens, rights of call or first refusal, encumbrances 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 one-thousandths of a Preferred Share for which a Right is 
     exercisable immediately prior to the first occurrence of a Section 13 
     Event (or, if a Section 11(a)(ii) Event has occurred prior to the first 
     occurrence of a Section 13

<PAGE>
                           26           

     Event, multiplying the number of such shares for which a
     Right was exercisable immediately prior to the first
     occurrence of a Section 11(a)(ii) 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 "Purchase 
       Price" for each Right and for all purposes of this Agreement) by 50% of 
       the current per share market price of the Common Shares of such 
       Principal Party (determined pursuant to Section 11(d) hereof) on the 
       date of consummation of such Section 13 Event; 

         (ii) such Principal Party shall thereafter be liable for, and 
   shall assume, by virtue of such consolidation, merger, sale or transfer, 
   all the obligations and duties of the Company pursuant to this Agreement;

        (iii) 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 to such Principal Party; and 

         (iv) such Principal Party shall take such steps (including, 
   but not limited to, the reservation of a sufficient number of its Common 
   Shares in accordance with Section 9 hereof) in connection with such 
   consummation as may be necessary to assure that the provisions hereof 
   shall thereafter be applicable, as nearly as reasonably may be, in 
   relation to the Common Shares thereafter deliverable upon the exercise 
   of the Rights.

          (b)  "Principal Party" shall mean

       (i)  in the case of any transaction described in (x) or (y) of 
 the first sentence of paragraph (a) of this Section 13, the Person that 
 is the issuer of any securities into which Common Shares of the Company 
 are converted in such merger of consolidation, and if no securities are 
 so issued, the Person that is the other party to the merger or 
 consolidation (including, if applicable, the Company, if it is the 
 surviving corporation); and

      (ii) in the case of any transaction described in (z) of the 
 first sentence of paragraph (a) of this Section 13, the Person that is 
 the party receiving the greatest portion of the assets or earning power 
 transferred pursuant to such transaction or transactions;

<PAGE>

                           27     

  provided, however, that in any such case (1) if the Common Shares of 
  such Person are not at such time and have not been continuously over the 
  preceding 12-month period registered under Section 12 of the Exchange 
  Act, and such Person is a direct or indirect Subsidiary or Affiliate of 
  another Person, "Principal Party" shall refer to such other Person; (2) 
  in case such Person is a Subsidiary, directly or indirectly, or 
  Affiliate of more than one Person, the Common Shares of two or more of 
  which are and have been so registered, "Principal Party" shall refer to 
  whichever of such Persons is the issuer of the Common Shares having the 
  greatest aggregate market value; and (3) in case such Person is owned, 
  directly or indirectly, by a joint venture formed by two or more Persons 
  that are not owned, directly or indirectly, by the same Person, the 
  rules set forth in (l) and (2) above shall apply to each of the chains 
  of ownership having an interest in such joint venture as if such party 
  were a "Subsidiary" of both or all of such joint venturers and the 
  Principal Parties in each such chain shall bear the obligations set 
  forth in this Section l3 in the same ratio as their direct or indirect 
  interests in such Person bear to the total of such interests.

          (c)  The Company shall not consummate any such consolidation, 
merger, sale or transfer 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 each Principal Party and 
each other Person who may become a Principal Party as a result of such 
consolidation, merger, sale or transfer shall have executed and delivered to 
the Rights Agent a supplemental agreement providing for the terms set forth 
in paragraphs (a) and (b) of this Section 13 and further providing that, as 
soon as practicable after the date of any Section 13 Event, the Principal 
Party at its own expense shall:

          (i)  prepare and file a registration statement under the 
    Securities Act with respect to the Rights and the securities purchasable 
    upon the exercise of the Rights on an appropriate form, will use its 
    best efforts to cause such registration statement to become effective as 
    soon as practicable after such filing and will 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;

          (ii) use its best efforts to qualify or register the Rights 
    and the securities purchasable upon exercise of the Rights under the 
    securities laws of such jurisdictions as may be necessary or appropriate;

         (iii) 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 

<PAGE>

                           28

          (iv) deliver to holders of the Rights historical financial 
    statements for the Principal Party and each of its Affiliates which 
    comply in all material respects with the requirements for registration 
    on Form 10 under the Exchange Act.

The provisions of this Section 13 shall similarly apply to successive mergers 
or consolidations or sales or other transfers.  If a Section 13 Event shall 
occur at any time after the occurrence of a Section 11(a)(ii) Event, the 
Rights which have not theretofore been exercised shall thereafter become 
exercisable solely in the manner described in paragraph (a) of this Section 
13.

     Section 14.  Additional Covenants.

          (a)  The Company covenants and agrees that it shall not at any time 
after the Distribution Date (i) consolidate with, (ii) merge with or into, or 
(iii) sell or transfer to, in one or more transactions, assets or earning 
power aggregating more than 50% of the assets or earning power of the Company 
and its Subsidiaries taken as a whole, any other Person if at the time of or 
after such consolidation, merger or sale there are any charter or by-law 
provisions or any rights, warrants or other instruments outstanding or any 
other action taken which would diminish or otherwise eliminate the benefits 
intended to be afforded by the Rights.  The Company shall not consummate any 
such consolidation, merger or sale unless prior thereto the Company and such 
other Person shall have executed and delivered to the Rights Agent a 
supplemental agreement evidencing compliance with this subsection.

          (b)  The Company covenants and agrees that, after the Distribution 
Date, it will not, except as permitted by Section 24, Section 25 or Section 
28 hereof, take any action if at the time such action is taken it is 
reasonably foreseeable that such action will substantially diminish or 
otherwise eliminate the benefits intended to be afforded by the Rights.

     Section 15.  Fractional Rights and Fractional Shares.

          (a)  The Company shall not be required to issue fractions of 
Rights, except prior to the Distribution Date as provided in Section 11(n), 
or to distribute Rights Certificates which evidence fractional Rights.  In 
lieu of such fractional Rights, there shall be paid to the registered holders 
of the Rights Certificates with regard to which such fractional Rights would 
otherwise be issuable, an amount in cash equal to the same fraction of the 
current market value of a whole Right.  For the purposes of this Section 
15(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.  The closing price for 
any day shall be the last sale price, regular way, or, in case no such sale 
takes place on such day, the average of the closing bid and asked prices, 
regular way, in 



<PAGE>

                           29

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 Rights are 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 Rights are listed or 
admitted to trading or, if the Rights are not listed or admitted to trading 
on any national securities exchange, the last quoted price or, if not so 
quoted, the average of the high bid and low asked prices in the 
over-the-counter market, as reported by NASDAQ or such other system then in 
use or, if on any such date the Rights are not quoted by any such 
organization, the average of the closing bid and asked prices as furnished by 
a professional market maker making a market in the Rights selected by the 
Board of Directors of the Company.  If on any such date no such market maker 
is making a market in the Rights, the fair value of the Rights on such date 
as determined in good faith by the Board of Directors of the Company shall be 
used.

          (b)  The Company shall not be required to issue fractions of 
Preferred Shares (other than fractions which 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 which are integral multiples of one one-thousandth of a 
Preferred Share).  Fractions of Preferred Shares in integral multiples of one 
one-thousandth of a Preferred Share may, at the election of the Company, be 
evidenced by depositary receipts, pursuant to an appropriate agreement 
between the Company and a depositary selected by it; provided, that such 
agreement shall provide that the holders of such depositary receipts shall 
have all the rights, privileges and preferences to which they are entitled as 
beneficial owners of the Preferred Shares represented by such depositary 
receipts.  In lieu of fractional Preferred Shares that are not integral 
multiples of one one-thousandth of a Preferred Share, the Company shall pay 
to the registered holders of Rights Certificates at the time such Rights are 
exercised as herein provided an amount in cash equal to the same fraction of 
the current market value of one Preferred Share.  For the purposes of this 
Section 15(b), the current market value of a Preferred Share shall be the 
closing price of a Preferred Share (as determined pursuant to Section 
11(d)(ii) hereof) for the Trading Day immediately prior to the date of such 
exercise.

          (c)  Following the occurrence of one of the transactions or events 
specified in Section 11 giving rise to the right to receive Common Shares 
upon the exercise of a Right, the Company shall not be required to issue 
fractions of Common Shares upon exercise of the Rights or to distribute 
certificates which evidence fractional Common Shares.  In lieu of fractional 
Common Shares, the Company may 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 15(c), the


<PAGE>

                           30

current market value shall be determined in the manner set forth in Section 
11(d) hereof for the Trading Day immediately prior to the date of such 
exercise.

          (d)  The holder of a Right by the acceptance of the Right expressly 
waives his right to receive any fractional Rights or any fractional shares 
upon exercise of a Right (except as provided above).

     Section 16.  Rights of Action.  Excepting the rights of action given to 
the Rights Agent under Section 19 hereof, all rights of action in respect of 
this Agreement are vested in the respective registered holders of the Rights 
Certificates (and, prior to the Distribution Date, the registered holders of 
the Common Shares); and any registered holder of any Rights Certificate (or, 
prior to the Distribution Date, of the Common Shares), subject to Section 
7(e), 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 own behalf and for his own benefit, enforce, and may 
institute and maintain any suit, action or proceeding against the Company to 
enforce, or otherwise act in respect of, his right to exercise the Rights 
evidenced by such 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 17.  Agreement of Rights Holders.  Every holder of a Right, by 
accepting the same, consents and agrees with the Company and the Rights Agent 
and with every other holder of a Right that:

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

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

          (c)  subject to Section 6 and Section 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

<PAGE>

                           31

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; 
and 

          (d)  notwithstanding anything in this Agreement to the contrary, 
neither the Company nor the Rights Agent shall have any liability to any 
holder of a Right or a beneficial interest in a Right or other Person as a 
result of its inability to perform any of its obligations under this 
Agreement by reason of any preliminary or permanent injunction or other 
order, decree or ruling issued by a court of competent jurisdiction or by a 
governmental, regulatory or administrative agency or commission, or any 
statute, rule, regulation or executive order promulgated or enacted by any 
governmental authority, prohibiting or otherwise restraining performance of 
such obligation; provided, however, the Company must use its best efforts to 
have any such order, decree or ruling lifted or otherwise overturned as soon 
as possible.  

     Section 18.  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 26 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 19.  Concerning the Rights Agent.  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 gross 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 arising therefrom, directly or indirectly.

     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

<PAGE>

for Preferred Shares or other securities of the Company, instrument of 
assignment or transfer, power of attorney, endorsement, affidavit, letter, 
notice, direction, consent, certificate, statement, or other paper or 
document believed by it to be genuine and to be signed, executed and, where 
necessary, verified or acknowledged, by the proper Person or Persons.

     Section 20.  Merger or Consolidation or Change of Name of Rights Agent.  
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 stock 
transfer or corporate trust business of the Rights Agent or any successor 
Rights Agent, shall be the successor to the Rights Agent under this Agreement 
without the execution or filing of any paper or any further act on the part 
of any of the parties hereto, provided that such corporation would be 
eligible for appointment as a successor Rights Agent under the provisions of 
Section 22 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.

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

     Section 21.  Duties of Rights Agent.  The Rights Agent undertakes the 
duties and obligations imposed by this Agreement upon the following terms and 
conditions, by all of which the Company and the holders of Rights 
Certificates, by their acceptance thereof, shall be bound:

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

<PAGE>

                           33

          (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) 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 President, any 
Executive Vice President, any Vice President, the Treasurer or the Clerk 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 gross negligence, bad faith or willful 
misconduct.

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

          (e)  The Rights Agent shall not be under any responsibility in 
respect of the validity of this Agreement or the execution and delivery 
hereof (except the due execution hereof by the Rights Agent) or in respect of 
the validity or execution of any Rights Certificate (except its 
countersignature thereof); nor shall it be responsible for any breach by the 
Company of any covenant or condition contained in this Agreement or in any 
Rights Certificate; nor shall it be responsible for any adjustment required 
under the provisions of Section 11 or Section 13 hereof or for the manner, 
method or amount of any adjustment or the ascertaining of the existence of 
facts that would require any such adjustment (except with respect to the 
exercise of Rights evidenced by Rights Certificates after receipt of a 
certificate furnished pursuant to Section 12 describing any such adjustment); 
nor shall it be responsible for any determination by the Board of Directors 
of the Company of the current market value of the Rights or Preferred Shares 
or Common Shares; 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 or other securities to be issued pursuant to this Agreement 
or any Rights Certificate or as to whether any Preferred Shares or other 
securities will, when issued, be validly authorized and issued, fully paid 
and nonassessable.

          (f)  The Company agrees that it will perform, execute, acknowledge 
and deliver or cause to be performed, executed, acknowledged and delivered 
all such further and other acts, instruments and assurances as may reasonably 
be required by

<PAGE>

                           34

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 President, any Executive Vice President, any Vice President, the 
Clerk or the Treasurer of the Company, and to apply to such officers for 
advice or instructions in connection with its duties, and it shall not be 
liable for any action taken or suffered 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 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.

     Section 22.  Change of Rights Agent.  The Rights Agent or any successor 
Rights Agent may resign and be discharged from its duties under this 
Agreement upon 30 days' notice in writing mailed to the Company and to each 
transfer agent of the Common Shares or Preferred Shares by registered or 
certified mail, and to the holders of the Rights Certificates by first-class 
mail at the expense of the Company. 

<PAGE>

                           35

 The Company may remove the Rights Agent or any successor Rights Agent upon 
30 days' notice in writing, mailed to the Rights Agent or successor Rights 
Agent, as the case may be, and to each transfer agent of the Common Shares 
and Preferred 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 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 Rights 
Certificate for inspection by the Company), then the registered holder of any 
Rights Certificate may apply to any court of competent jurisdiction for the 
appointment of a new Rights Agent.  Any successor Rights Agent, whether 
appointed by the Company or by such a court, shall be a corporation organized 
and doing business under the laws of the United States or any state of the 
United States so long as such corporation is in good standing, which is 
authorized under such laws to exercise corporate trust or stock transfer 
powers and is subject to supervision or examination by federal or state 
authority and which has at the time of its appointment as Rights Agent a 
combined capital and surplus of at least $100 million. After appointment, the 
successor Rights Agent shall be vested with the same powers, rights, duties 
and responsibilities as if it had been originally named as Rights Agent 
without further act or deed; but the predecessor Rights Agent shall deliver 
and transfer to the successor Rights Agent any property at the time held by 
it hereunder, and execute and deliver any further assurance, conveyance, act 
or deed necessary for the purpose.  Not later than the effective date of any 
such appointment, the Company shall file notice thereof in writing with the 
predecessor Rights Agent and each transfer agent of the Common Shares and 
Preferred 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 22, 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 23.  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.

     Section 24.  Redemption.

          (a)  The Rights may be redeemed by action of the Board of Directors 
pursuant to paragraph (b) of this Section 24 or by action of the Continuing 

<PAGE>

                           36

Directors pursuant to paragraph (c) of this Section 24, and shall not be 
redeemed in any other manner, except as provided by Section 32.

          (b)  The Board of Directors of the Company may, at its option, at 
any time prior to the earlier of (x) the close of business on the tenth day 
following a Shares Acquisition Date, or (y) 5:00 p.m., Boston local time, on 
the Final Expiration Date, redeem all but not less than all the then 
outstanding Rights at a redemption price of $.001 per Right, appropriately 
adjusted to reflect any stock split, stock dividend or similar transaction 
occurring after the date hereof (such redemption price being hereinafter 
referred to as the "Redemption Price"); provided, however, if the Board of 
Directors of the Company authorizes redemption of the Rights in either of the 
circumstances set forth in clauses (i) and (ii) of this proviso, then there 
must be Continuing Directors then in office and such authorization shall 
require the concurrence of at least two-thirds of such Continuing Directors:  
(i) such authorization occurs on or after the time a Person becomes an 
Acquiring Person or (ii) such authorization occurs on or after the date of a 
change (resulting from one or more proxy or consent solicitations) in a 
majority of the directors in office at the commencement of such solicitations 
if any Person who is a participant in such solicitations has stated (or, if 
upon the commencement of such solicitations, a majority of the Board of 
Directors of the Company has determined in good faith) that such Person (or 
any of its Affiliates or Associates) intends to take, or may consider taking, 
any action that would result in such Person becoming an Acquiring Person or 
that would cause the occurrence of a Triggering Event.  The redemption of the 
Rights by the Board of Directors may be made effective at such time on such 
basis and with such conditions as the Board of Directors in its sole 
discretion may establish.

          (c)  In addition to the right of redemption reserved in Section 
24(b), the Continuing Directors then in office may redeem all but not less 
than all of the then outstanding Rights at the Redemption Price following the 
occurrence of a Shares Acquisition Date but prior to any event described in 
Section 11(a)(ii)(A) or (C) or Section 13(a), at their option, upon the 
affirmative vote or written consent of not less than two-thirds of such 
Continuing Directors:

          (i)  if:

          (A)  an Acquiring Person shall have transferred or otherwise 
     disposed of a number of Common Shares in one transaction or series of 
     transactions, not directly or indirectly involving the Company or any of 
     its Subsidiaries, which did not result in the occurrence of a Triggering 
     Event, or the Company (with the approval of at least two-thirds of 
     Continuing Directors) shall have issued additional equity securities, in 
     either instance such that such Person is thereafter a Beneficial Owner 
     of less than 10% of the outstanding Common Shares; and 

<PAGE>

                           37

          (B)  there is no other Acquiring Person immediately following 
     the occurrence of the event described in clause (A); or 

          (ii) in connection with any Section 13(a) Event in which all 
     holders of Common Shares are treated alike and not involving (other than 
     as a holder of Common Shares being treated like all other such holders) 
     an Acquiring Person or an Affiliate or Associate of an Acquiring Person 
     or any other Person in which such Acquiring Person, Affiliate or 
     Associate has any interest, or any other Person acting directly or 
     indirectly on behalf of or in association with any Acquiring Person, 
     Affiliate or Associate.  

     Any redemption of the Rights by the Continuing Directors may
     be made effective at such time, on such basis and with such
     conditions as the Continuing Directors in their sole
     discretion may establish.

        (d)  Immediately upon the action of the Board of Directors or the 
Continuing Directors, as the case may be, of the Company ordering the 
redemption of the Rights pursuant to paragraph (b) or paragraph (c) of this 
Section 24, and without any further action and without any notice, the right 
to exercise the Rights will terminate and the only right thereafter of the 
holders of Rights shall be to receive the Redemption Price.  The Company 
shall promptly give public notice of any such redemption; provided, however, 
that the failure to give, or any defect in, any such notice shall not affect 
the validity of such redemption.  Within 10 days after such action ordering 
the redemption of the Rights pursuant to paragraph (b) or (c), as the case 
may be, the Company shall mail a notice of redemption to all the holders of 
the then outstanding Rights 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.  The 
Company may, at its option, pay the Redemption Price in cash, Common Shares 
(based on the current per share market price of the Common Shares as of the 
time of redemption) or any other form of consideration deemed appropriate by 
the Board of Directors. Notwithstanding anything contained in this Agreement 
to the contrary, the Rights shall not be exercisable after the first 
occurrence of a Section 11(a)(ii) Event until such time as the Company's 
right of redemption under Section 24(b) has expired.  

     Section 25.  Exchange.

          (a)  The Continuing Directors then in office may, at their option, 
upon the affirmative vote or written consent of not less than two-thirds of 
such Continuing Directors, at any time after the occurrence of a Section 
11(a)(ii) Event,
                                 
<PAGE>

                           38

exchange all or part of the then outstanding and exercisable Rights (which 
shall not include Rights that have become void pursuant to the provisions of 
Section 7(e) hereof) for Common Shares at an exchange ratio of one Common 
Share per Right, appropriately adjusted to reflect any stock split, stock 
dividend or similar transaction occurring after the date hereof (such 
exchange ratio being hereinafter referred to as the "Exchange Ratio").  
Notwithstanding the foregoing, the Continuing 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 Continuing Directors of the 
Company ordering the exchange of any Rights pursuant to subsection (a) of 
this Section 25 and without any further action and without any notice, the 
right to exercise such Rights shall terminate and the only right thereafter 
of a holder of such Rights shall be to receive that number of Common Shares 
equal to the number of such Rights held by such holder multiplied by the 
Exchange Ratio. The Company shall promptly give public notice of any such 
exchange; provided, however, that the failure to give, or any defect in, such 
notice shall not affect the validity of such exchange.  The Company promptly 
shall mail a notice of any such exchange to all of the holders of such Rights 
at their last addresses as they appear upon the registry books of the Rights 
Agent.  Any notice which is mailed in the manner herein provided shall be 
deemed given, whether or not the holder receives the notice.  Each such 
notice of exchange will state the method by which the exchange of the 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 any exchange pursuant to this Section 25, the Company, at 
its option, may substitute Preferred Shares (or equivalent preferred shares, 
as such term is defined in Section 11(b) hereof) for Common Shares 
exchangeable for Rights, at the initial rate of one one-thousandth of a 
Preferred Share (or equivalent preferred share) for each Common Share, as 
appropriately adjusted to reflect adjustments in the voting rights of the 
Preferred Shares pursuant to the terms thereof, so that the fraction of a 
Preferred Share delivered in lieu of each Common Share shall have the same 
voting rights as one Common Share.

          (d)  In the event that there shall not be sufficient Common Shares 
or Preferred Shares issued but not outstanding or authorized but unissued to 
permit any exchange of Rights as contemplated in accordance with this Section 
25, the Company 

<PAGE>

                           39

shall take all such action as may be necessary to authorize additional Common 
Shares or Preferred Shares for issuance upon exchange of the Rights.

          (e)  The Company shall not be required to issue fractions of Common 
Shares or to distribute certificates which evidence fractional Common Shares. 
 In lieu of such fractional Common Shares, the Company shall pay to the 
registered holders of the Rights Certificates with regard to which such 
fractional Common Shares would otherwise be issuable an amount in cash equal 
to the same fraction of the current market value of a whole Common Share.  
For the purposes of this paragraph (e), the current market value of a whole 
Common Share shall be the closing price of a Common Share (as determined 
pursuant to Section 11(d)(i) hereof) for the Trading Day immediately prior to 
the date of exchange pursuant to this Section 25.

     Section 26.  Notice of Certain Events.

          (a)  In case the Company shall propose, at any time after the 
Distribution Date, (i) to pay any dividend payable in stock of any class to 
the holders of its Preferred Shares or to make any other distribution to the 
holders of its Preferred Shares (other than a regular quarterly cash 
dividend), (ii) to offer to the holders of its Preferred Shares rights or 
warrants to subscribe for or to purchase any additional Preferred Shares or 
shares of stock of any class or any other securities, rights or options, 
(iii) to effect any reclassification of its Preferred Shares (other than a 
reclassification involving only the subdivision of outstanding Preferred 
Shares), (iv) to effect any consolidation or merger into or with, or to 
effect any sale or other transfer (or to permit one or more of its 
Subsidiaries to effect any sale or other transfer), in one or more 
transactions, of 50% or more of the assets or earning power of the Company 
and its Subsidiaries (taken as a whole) to, any other Person, (v) to effect 
the liquidation, dissolution or winding-up of the Company, or (vi) to declare 
or pay any dividend on the Common Shares payable in Common Shares or to 
effect a subdivision, combination or consolidation of the Common Shares (by 
reclassification or otherwise than by payment of dividends in Common Shares), 
then, in each such case, the Company shall give to each holder of a Rights 
Certificate, in accordance with Section 27 hereof, a notice of such proposed 
action, which shall specify the record date for the purposes of such stock 
dividend, or distribution of rights or warrants, or the date on which such 
reclassification, consolidation, merger, sale, transfer, liquidation, 
dissolution, or winding-up is to take place and the date of participation 
therein by the holders of the Common Shares and/or Preferred Shares, if any 
such date is to be fixed, and such notice shall be so given in the case of 
any action covered by clause (i) or (ii) above at least 20 days prior to the 
record date for determining holders of the Preferred Shares for purposes of 
such action, and in the case of any such other action, at least 20 days prior 
to the date of the taking of such proposed action or the date of 
participation therein by the holders of the Common Shares and/or Preferred 
Shares, whichever shall be the earlier.

<PAGE>

                           40        

          (b)  In case any Section 11(a)(ii) Event shall occur, (i) the 
Company shall as soon as practicable thereafter give to each holder of a 
Rights Certificate, in accordance with Section 27 hereof, a notice of the 
occurrence of such event, which notice shall describe such event and the 
consequences of such event to holders of Rights under Section 11(a)(ii) 
hereof, and (ii) all references in the preceding paragraph to Preferred 
Shares shall be deemed thereafter to refer to Common Shares or, if 
appropriate, other securities.

     Section 27.  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

Company or the Rights Agent to the holder of any Rights Certificate or 
certificate representing Common Shares shall be sufficiently given or made if 
sent by first-class mail, postage prepaid, addressed to such holder at the

     Section 28.  Supplements and Amendments.  Prior to the Distribution Date 
and subject to the penultimate sentence of this Section 28, the Company and 
the Rights Agent shall, if the Company so directs, supplement or amend any 
provision of this Agreement without the approval of any holders of 
certificates representing Common Shares.  From and after the Distribution 
Date and subject to the penultimate sentence of this Section 28, the Company 
and the Rights Agent shall, if the Company

<PAGE>

                           41

so directs, supplement or amend this Agreement without the approval of any 
holders of Rights Certificates in order (i) to cure any ambiguity, (ii) to 
correct or supplement any provision contained herein which may be defective 
or inconsistent with any other provisions herein, (iii) to shorten or 
lengthen any time period hereunder (which lengthening or shortening, 
following the first occurrence of an event set forth in clauses (i) or (ii) 
of the proviso to Section 24(b) hereof, shall be effective only if there are 
Continuing Directors and shall require the concurrence of at least two-thirds 
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 
Certificates (other than an Acquiring Person or any Affiliate or Associate of 
an Acquiring Person); provided, this Agreement may not be supplemented or 
amended to lengthen, pursuant to clause (iii) of this sentence, (A) a time 
period relating to when the Rights may be redeemed at such time as the Rights 
are not then redeemable, or (B) any other time period unless such lengthening 
is for the purpose of protecting, enhancing or clarifying the rights of, 
and/or the benefits to, the holders of Rights (other than an Acquiring Person 
or any Affiliate or Associate of an Acquiring Person).  Upon the delivery of 
a certificate from an appropriate officer of the Company which states that 
the proposed supplement or amendment is in compliance with the terms of this 
Section 28, the Rights Agent shall execute such supplement or amendment 
unless the Right Agent shall have determined in good faith that such 
supplement or amendment would adversely affect its interests under this 
Agreement.  Notwithstanding anything contained in this Agreement to the 
contrary, no supplement or amendment shall be made that changes the 
Redemption Price, the Final Expiration Date, the Purchase Price or the number 
of one-thousandths of a Preferred Share for which a Right is exercisable.  
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 29.  Determination 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 or 
any other securities of which any Person is the Beneficial Owner, shall be 
made in accordance with the last sentence of Rule 13d-3(d)(l)(i) of the 
General Rules and Regulations under the Exchange Act as in effect on the date 
of this Agreement.  Except for those powers specifically granted in this 
Agreement to the Continuing Directors, the Board of Directors of the Company 
shall have the exclusive power and authority to administer this Agreement and 
to exercise all rights and powers specifically granted to the Board, or the 
Company, or as may be necessary or advisable in the administration of this 
Agreement, including, without limitation, the right and power to (i) 
interpret the provisions of this Agreement, and (ii) make all determinations 
deemed necessary or advisable for the administration of this Agreement 
(including a determination to redeem or not redeem the Rights or to amend the 
Agreement).  All such actions, calculations,

<PAGE>

                           42

interpretations and determinations and any actions, calculations, 
interpretations and determinations by the Continuing Directors with respect 
to the powers granted to them under this Agreement (including, for purposes 
of clause (y) below, all omissions with respect to the foregoing) which are 
done or made by the Board or by the Continuing Directors, as the case may be, 
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 any Director to any liability to the holders 
of the Rights Certificates.

     Section 30.  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.

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, of 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, of the Common Shares).

     Section 32.  Severability.  If any term, provision, covenant or 
restriction of this Agreement is held by a court of competent jurisdiction or

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 24(b) hereof shall be reinstated and shall 
not expire until the close of business on the tenth day following the date of 
such determination by the Board of Directors.

                                                               Exhibit A to
                                                               Rights Agreement

   Preferences, Voting Powers and Qualifications and Special or Relative 
Rights or Privileges of the Series A Junior Participating Preferred Stock.

    Section 1.  Designation and Amount.  The shares of such series shall be
designated as "Series A Junior Participating Preferred Stock" (the "Series A
Preferred Stock") and the number of shares constituting the Series A Preferred
Stock shall be 100,000.  Such number of shares may be increased or decreased by
vote of the Board of Directors; provided, that no decrease shall reduce the
number of shares of Series A Preferred Stock to a number less than the number of
shares then outstanding plus the number of shares reserved for issuance upon the
exercise of outstanding options, rights or warrants or upon the conversion of
any outstanding securities issued by the Corporation.

    Section 2.  Dividends and Distributions.

    (A)  Subject to the rights of the holders of any shares of any series of
    Preferred Stock (or any similar stock) ranking prior and superior to the
    Series A Preferred Stock with respect to dividends, the holders of shares
    of Series A Preferred Stock, in preference to the holders of Common Stock,
    no par value per share (the "Common Stock"), of the Corporation, and of any
    other junior 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 first 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 Preferred Stock, in an amount per share
    (rounded to the nearest cent) equal to the greater of (a) $1.00 or
    (b) 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 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 Preferred Stock.  In the event the
    Corporation shall at any time (i) declare a dividend on the Common Stock
    payable in shares of Common Stock, (ii) subdivide the outstanding shares of
    Common Stock, (iii) combine the outstanding shares of Common Stock into a
    smaller number of shares or (iv) issue any of its shares of capital stock
    in a reclassification of the outstanding shares of Common Stock (including
    any such reclassification in connection with a consolidation or merger in
    which the Corporation is the continuing or surviving entity), then in each
    such case the amount to which holders of shares of Series A Preferred Stock
    were entitled immediately prior to 

<PAGE>

                                    -2-

    such event under clause (b) 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 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 Preferred Stock as provided in paragraph (A) of this Section immediately
    after it declares a dividend or distribution on the Common Stock (other
    than a dividend payable in shares of Common Stock); provided that, in the
    event no dividend or distribution shall have been declared on the Common
    Stock during the period between any Quarterly Dividend Payment Date and the
    next subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per
    share on the Series A Preferred Stock shall nevertheless be payable on such
    subsequent Quarterly Dividend Payment Date.

    (C)  Dividends shall begin to accrue and be cumulative on outstanding
    shares of Series A Preferred Stock from the Quarterly Dividend Payment Date
    next preceding the date of issue of such shares, 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 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 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 Preferred Stock entitled to receive payment
    of a dividend or distribution declared thereon, which record date shall be
    not more than 60 days prior to the date fixed for the payment thereof.

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

    (A)  Subject to the provision for adjustment hereinafter set forth, each
    share of Series A 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 (i) declare a
    dividend on the Common Stock payable in shares of Common Stock,
    (ii) subdivide the outstanding shares of Common Stock, (iii) combine the
    outstanding shares of Common Stock into a 

<PAGE>

                                    -3-

    smaller number of shares or (iv) issue any of its shares of capital 
    stock in a reclassification of the outstanding shares of Common Stock 
    (including any such reclassification in connection with a consolidation 
    or merger in which the Corporation is the continuing or surviving 
    entity), then in each such case the number of votes per share to which 
    holders of shares of Series A 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, in any other Certificate of Vote
    of Directors establishing a series of Preferred Stock or any similar stock,
    or by law, the holders of shares of Series A Preferred Stock and the
    holders of shares of Common Stock and any other capital stock of the
    Corporation having general voting rights shall vote together as one class
    on all matters submitted to a vote of stockholders of the Corporation.

    (C)  Except as set forth herein, or as otherwise provided by law, holders
    of Series A 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)  Whenever quarterly dividends or other dividends or distributions
    payable on the Series A 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 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 Preferred Stock;

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

<PAGE>

                                    -4-

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

          (iv)     redeem or purchase or otherwise acquire for consideration 
         any shares of Series A Preferred Stock, or any shares of stock ranking
         on a parity with the Series A 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.

    (B)  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 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
subject to the conditions and restrictions on issuance set forth herein, in the
Corporation's Restated Articles of Organization or in any other Certificate of
Vote of Directors establishing a series of Preferred Stock or any similar stock
or as otherwise required by law.

    Section 6.  Liquidation, Dissolution or Winding Up.  Upon any liquidation,
dissolution or winding up of the Corporation, no distribution shall be made
(1) to the holders of shares of stock ranking junior (either as to dividends or
upon liquidation, dissolution or winding up) to the Series A Preferred Stock
unless, prior thereto, the holders of shares of Series A Preferred Stock shall
have received $10.00 per share, plus an amount equal to accrued and unpaid
dividends and distributions thereon, whether or not declared, to the date of
such payment; provided that the holders of shares of Series A Preferred Stock
shall be entitled to receive an aggregate amount per share, subject to the
provision for adjustment hereinafter set forth, equal to 1,000 times the
aggregate amount to be distributed per share to holders of shares of Common
Stock, or (2) to the holders of shares of stock ranking on a parity (either as
to dividends or upon liquidation, dissolution or winding up) with the Series A
Preferred Stock, except distributions made ratably on 

<PAGE>

                                    -5-

the Series A Preferred Stock and all such parity stock in proportion to the 
total amounts to which the holders of all such shares are entitled upon such 
liquidation, dissolution or winding up.  In the event the Corporation shall 
at any time (i) declare a dividend on the Common Stock payable in shares of 
Common Stock, (ii) subdivide the outstanding shares of Common Stock, (iii) 
combine the outstanding shares of Common Stock into a smaller number of 
shares or (iv) issue any of its shares of capital stock in a reclassification 
of the outstanding shares of Common Stock (including any such 
reclassification in connection with a consolidation or merger in which the 
Corporation is the continuing or surviving entity), then in each such case 
the aggregate amount to which holders of shares of Series A Preferred Stock 
were entitled immediately prior to such event under the proviso in clause (1) 
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 
outstanding immediately after such event and the denominator of which is the 
number of shares of Common Stock that were outstanding immediately prior to 
such event.

    Section 7.  Consolidation, Merger, etc.  In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case each share of
Series A Preferred Stock shall at the same time be similarly exchanged or
changed into 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 (i) declare a dividend on the
Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding
shares of Common Stock, (iii) combine the outstanding shares of Common Stock
into a smaller number of shares or (iv) issue any of its shares of capital stock
in a reclassification of the outstanding shares of Common Stock (including any
such reclassification in connection with a consolidation or merger in which the
Corporation is the continuing or surviving entity), 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 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 Preferred Stock shall
not be redeemable.

    Section 9.  Rank.  The Series A Preferred Stock shall rank, with respect to
the payment of dividends and the distribution of assets, junior to all other
series of the Corporation's preferred stock, unless the terms of any such series
shall provide otherwise.

    Section 10.  Amendment.  The Restated Articles of Organization, as amended,
of 

<PAGE>

                                    -6-

the Corporation shall not be amended in any manner which would materially
alter or change the powers, preferences or special rights of the Series A
Preferred Stock so as to affect them adversely without the affirmative vote of
the holders of at least two-thirds of the outstanding shares of Series A
Preferred Stock, voting together as a single class; it being understood that
nothing in this Section 10 shall be deemed to restrict the Corporation from
designating additional shares of Series A Preferred Stock if the Board of
Directors determines that it is necessary to do so in order to achieve the
purposes of the Rights Agreement, dated June 26, 1997 between the Corporation
and State Street Bank and Trust Company, as Rights Agent.

    Section 11.  Fractional Shares.  Series A 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 Preferred Stock.

Rights Agent designated for such purpose, or at the office of its successor 
as Rights Agent designated for such purpose, one one-thousandth of a fully 
paid nonassessable share of Series A Junior Participating Preferred Stock, 
par value $.01 per share (the "Preferred Shares"), of the Company, at a 
purchase price of $22.00 per one one-thousandth of a Preferred Share (the

Price as of July 9, 2007, based on the Preferred Shares as constituted at

subject to modification and adjustment upon the happening of certain events.

  This Rights Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated herein by reference and made a part hereof and to which

                            SUMMARY OF RIGHTS TO PURCHASE
                                   PREFERRED SHARES



    As of June 24, 1997, the Board of Directors of UroMed Corporation, a
Massachusetts corporation (the "Company"), declared a dividend distribution of
one preferred share purchase right (a "Right") for each outstanding share of
common stock, no par value per share (the "Common Shares"), of the Company.  The
dividend is payable on July 9, 1997 (the "Record Date") to the stockholders of
record on that date.  Except as described below, each Right, when exercisable,
entitles the registered holder to purchase from the Company one one-thousandth
of a share of Series A Junior Participating Preferred Stock, par value $.01 per
share (the "Preferred Shares"), of the Company at a price of $22.00 per one
one-thousandth of a Preferred Share (the "Purchase Price"), subject to
adjustment.  The description and terms of the Rights are set forth in a Rights
Agreement (the "Rights Agreement") between the Company and State Street Bank and
Trust Company, as Rights Agent (the "Rights Agent").

    Initially, the Rights will be attached to all certificates representing
Common Shares then outstanding, and no separate Rights certificates will be
distributed.  Until the earlier to occur of (i) 10 business days following a
public announcement that a person or group of affiliated or associated persons
(an "Acquiring Person", which does not include certain institutional investors
which exceed temporarily the 15% threshold, and which does not include John G.
Simon, the current President and Chief Executive Officer of the Company, and his
associates so long as together they own less than 25% of the Common Shares) have
acquired beneficial ownership of 15% or more of the outstanding Common Shares
(the date of such an announcement being a "Shares Acquisition Date"), or (ii) 10
business days (or such later date as may be determined by action of the Board of
Directors prior to such time as any Person becomes an Acquiring Person)
following the commencement of, or announcement of an intention to make, a tender
offer or exchange offer the consummation of which would result in the beneficial
ownership by a person or group of 15% or more of such outstanding Common Shares
(the earliest of such dates being called the "Distribution Date"), the Rights
will be evidenced, with respect to any of the Common Share 

<PAGE>

                                    -2-

certificates outstanding as of the Record Date, by such Common Share 
certificate together with a copy of this Summary of Rights.

    The Rights Agreement provides that, until the Distribution Date, the Rights
will be transferred with and only with the Common Shares.  Until the
Distribution Date (or earlier redemption or expiration of the Rights), new
Common Share certificates issued after the Record Date upon transfer or new
issuance of Common Shares will contain a notation incorporating the Rights
Agreement by reference.  Until the Distribution Date (or earlier redemption or
expiration of the Rights), the surrender for transfer of any certificates for
Common Shares outstanding as of the Record Date, even without such notation or a
copy of this Summary of Rights being attached thereto, will also constitute the
transfer of the Rights associated with the Common Shares represented by such
certificate.  As soon as practicable following the Distribution Date, separate
certificates evidencing the Rights ("Rights Certificates") will be mailed to
holders of record of the Common Shares as of the close of business on the
Distribution Date, and the separate Rights Certificates alone will evidence the
Rights.

    The Rights are not exercisable until the Distribution Date.  The Rights
will expire on July 9, 2007 (the "Final Expiration Date"), unless the Rights are
earlier redeemed by the Company, as described below.

    The Purchase Price payable, and the number of Preferred Shares or other
securities or property issuable, upon exercise of the Rights are subject to
adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Preferred
Shares, (ii) upon the grant to holders of the Preferred Shares of certain rights
or warrants to subscribe for or purchase Preferred Shares at a price, or
securities convertible into Preferred Shares with a conversion price, less than
the then current market price of the Preferred Shares or (iii) upon the
distribution to holders of the Preferred Shares of evidences of indebtedness or
assets (excluding regular periodic cash dividends paid out of earnings or
retained earnings or dividends payable in Preferred Shares) or of subscription
rights or warrants (other than those referred to above).

    The number of outstanding Rights and the number of one one-thousandths of a
Preferred Share issuable upon exercise of each Right are also subject to
adjustment in the event of a stock split of the Common Shares or a stock
dividend on the Common Shares payable in Common Shares or subdivisions,
consolidations or combinations of the Common Shares occurring, in any such case,
prior to the Distribution Date.

    Preferred Shares purchasable upon exercise of the Rights will not be
redeemable.  Each Preferred Share will be entitled to a minimum preferential
quarterly dividend payment of $1 per share but will be entitled to an aggregate

<PAGE>

                                    -3-

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 minimum
preferential liquidation payment of $1,000 per share but will be entitled to an
aggregate payment of 1,000 times the payment made per Common Share.  Each
Preferred Share will have 1,000 votes, voting together with the Common Shares. 
Finally, in the event of any merger, consolidation or other transaction in which
Common Shares are exchanged, each Preferred Share will be entitled to receive
1,000 times the amount received per Common Share.  These rights are protected by
customary antidilution provisions.

    Because of the nature of the Preferred Shares' dividend, liquidation and
voting rights, the value of the one one-thousandth interest in a Preferred Share
purchasable upon exercise of each Right is intended to approximate the value of
one Common Share.

    In the event that, after the first date of public announcement by the
Company or an Acquiring Person that an Acquiring Person has become such, the
Company is involved in a merger or other business combination transaction in
which the Common Shares are exchanged or changed, or 50% or more of the
Company's consolidated assets or earning power are sold (in one transaction or a
series of transactions), proper provision will be made so that each holder of a
Right (other than an Acquiring Person) will thereafter have the right to
receive, upon the exercise thereof at the then current exercise price of the
Right, that number of shares of common stock of the acquiring company (or, in
the event there is more than one acquiring company, the acquiring company
receiving the greatest portion of the assets or earning power transferred) which
at the time of such transaction would have a market value of two times the
exercise price of the Right.

    In the event that (i) any person becomes an Acquiring Person, (ii) an
Acquiring Person engages in one or more "self-dealing" transactions as set forth
in the Rights Agreement, or (iii) during such time as there is an Acquiring
Person, there shall be a reclassification of securities or a recapitalization or
reorganization of the Company or other transaction or series of transactions
involving the Company which has the effect of increasing by more than 1% the
proportionate share of the outstanding shares of any class of equity securities
of the Company or any of its subsidiaries beneficially owned by the Acquiring
Person, proper provision shall be made so that each holder of a Right, other
than Rights beneficially owned by any Acquiring Person, will thereafter have the
right to receive upon exercise that number of Common Shares having a market
value of two times the exercise price of the Right.  Upon occurrence of any of
the events described in the immediately preceding sentence, any Rights that are,
or (under certain circumstances specified in the Rights Agreement) were,
beneficially owned by any Acquiring Person shall immediately become null and
void.  At any time after the occurrence of any such event and prior to the
acquisition by any person or group of 50% or more of the outstanding 

<PAGE>

                                    -4-

Common Shares, the Continuing Directors (as defined below) may exchange the 
Rights (other than Rights owned by an Acquiring Person and certain related 
persons which have become void), in whole or in part, at an exchange ratio of 
one Common Share, or one one-thousandth of a Preferred Share (or of a share 
of a class or series of the Company's preferred stock having equivalent 
rights, preferences and privileges), per Right (subject to adjustment).

    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.  No fractional Preferred Shares will be issued (other than
fractions which are integral multiples of one one-thousandth of a Preferred
Share, which may, at the election of the Company, be evidenced by depositary
receipts) and in lieu thereof, an adjustment in cash will be made based on the
market price of the Preferred Shares on the last trading day prior to the date
of exercise.

    At any time prior to the earlier of (i) the tenth day after a Shares
Acquisition Date, or (ii) the expiration of the Rights, the Board of Directors
may redeem the Rights in whole, but not in part, at a price of $.001 per Right
(the "Redemption Price").  Under certain circumstances set forth in the Rights
Agreement, such a redemption would require the concurrence of the Company's
"Continuing Directors", that is, any director who is not an Acquiring Person or
an affiliate or associate of an Acquiring Person and who was in office prior to
the date of the Rights Agreement or subsequently nominated by a majority of the
Continuing Directors.  Thereafter, the Rights may only be redeemed by the
Continuing Directors in whole, but not in part, at the Redemption Price,
(a) under certain circumstances described in the Rights Agreement involving a
disposition of Common Shares by the Acquiring Person such that the Acquiring
Person's common share ownership is reduced to 10% or less, or (b) if such
redemption is incidental to a merger or other business combination transaction
or series of transactions involving the Company but not involving an Acquiring
Person and satisfying certain other conditions.  The redemption of the rights
may be made effective at such time on such basis and with such conditions as the
Board of Directors or the Continuing Directors, as the case may be, in their
sole discretion may establish.  Immediately upon any redemption of the Rights,
the right to exercise the Rights will terminate and the only right of the
holders of Rights will be to receive the Redemption Price.

    Other than those provisions relating to the principal economic terms of the
Rights, any of the provisions of the Rights Agreement may be amended by the
Board of Directors of the Company prior to the Distribution Date.  After the
Distribution Date, the provisions of the Rights Agreement may be amended by the
Board (in certain circumstances, with the concurrence of the Continuing
Directors) in order to cure any ambiguity, to make changes that 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 

<PAGE>

                                    -5-

amendment to adjust the time period governing redemption shall be made at 
such time as the Rights are not redeemable.

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

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