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

        On September 16, 1996, the Board of Directors of Celgene Corporation
(the "Corporation") declared a dividend distribution of one right (a "Right") to
purchase one one-tenth of a share of the Common Stock, $0.01 par value, of the
Corporation (the "Common Shares") for each outstanding share of Common Stock,
payable to the stockholders of record on September 26, 1996 (the "Record Date").
The Board of Directors also authorized and directed the issuance of one Right
with respect to each Common Share issued thereafter until the Distribution Date
(as defined below) and, in certain circumstances, with respect to Common Shares
issued after the Distribution Date. Except as set forth below, each Right, when
it becomes exercisable, entitles the registered holder to purchase from the
Corporation one one-tenth of a Common Share at a price of $100.00 per whole
Common 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 Corporation and American Stock Transfer & Trust Company, as Rights
Agent (the "Rights Agent"), dated as of September 16, 1996.

        Initially, the Rights will be attached to all certificates representing
Common Shares then outstanding, and no separate Right Certificates will be
distributed. The Rights will separate from the Common Shares upon the earliest
to occur of (i) a person or group of affiliated or associated persons having
acquired beneficial ownership of 15% or more of the outstanding Common Shares
(except pursuant to a Permitted Offer, as hereinafter defined); or (ii) 10 days
(or such later date as the Board of Directors may determine) following the
commencement of, or announcement of an intention to make, a tender offer or
exchange offer the consummation of which would result in a person or group
becoming an Acquiring Person (as hereinafter defined) (the earliest of such
dates being called the "Distribution Date"). A person or group whose acquisition
of Common Shares causes a Distribution Date pursuant to clause (i) above is an
"Acquiring Person." The date that a person or group becomes an Acquiring Person
is the "Shares Acquisition Date." A person who acquires Common Shares pursuant
to a tender or exchange offer which is for all outstanding Common Shares at a
price and on terms which a majority of the Board of Directors determines (prior
to acquisition) to be adequate and in the best interests of the Corporation and
its stockholders (other than such person, its affiliates and associates) (a
"Permitted Offer") will not be deemed to be an Acquiring Person and such
person's ownership will not constitute a Distribution Date.

        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 the 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

                                                                 
                                                                      


<PAGE>
<PAGE>



following the Distribution Date, separate certificates evidencing the Rights
("Right Certificates") will be mailed to holders of record of the Common Shares
as of the close of business on the Distribution Date (and to each initial record
holder of certain Common Shares issued after the Distribution Date), and such
separate Right Certificates alone will evidence the Rights.

        The Rights are not exercisable until the Distribution Date, and will
expire at the close of business on September 15, 2006, unless earlier redeemed
by the Corporation as described below.

        In the event that any person becomes an Acquiring Person, each holder of
Rights (other than Rights that have become void as described below) will
thereafter have the right (the "Flip-In Right") to receive, upon exercise of
such Rights, the number of Common Shares (or, in certain circumstances, other
securities of the Corporation) having a value (immediately prior to such
triggering event) equal to two times the aggregate exercise price of such
Rights. The Board, at its option, may exchange each Right (other than those that
have become void as described below) for one Common Share in lieu of the Flip-In
Right, provided no person is the beneficial owner of 50% or more of the Common
Shares at the time of such exchange. Notwithstanding the foregoing, following
the occurrence of the event described above, all Rights that are or (under
certain circumstances specified in the Rights Agreement) were beneficially owned
by any Acquiring Person or any affiliate or associate thereof will be null and
void.

        In the event that, at any time following the Shares Acquisition Date,
(i) the Corporation is acquired in a merger or other business combination
transaction in which the holders of all of the outstanding Common Shares
immediately prior to the consummation of the transaction are not the holders of
all of the surviving corporation's voting power, or (ii) more than 50% of the
Corporation's assets or earning power is sold or transferred, then each holder
of Rights (except Rights which previously have been voided as set forth above)
shall thereafter have the right (the "Flip-Over Right") to receive, upon
exercise of such Rights, common shares of the acquiring company having a value
equal to two times the aggregate exercise price of the Rights; provided,
however, that the Flip Over Right shall not apply to any transaction described
in clause (i) if (x) such transaction is with a person or persons (or a wholly
owned subsidiary of any such person or persons) that acquired Common Shares
pursuant to a Permitted Offer and (y) the price and form of consideration
offered in such transaction is the same as that paid to all holders of Common
Shares whose shares were purchased to the Permitted Offer. The holder of a Right
will continue to have the Flip-Over Right whether or not such holder exercises
or surrenders the Flip-In Right.

        The Purchase Price payable, and the number of Common Shares or other
securities 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 Common Shares, (ii) upon
the grant to holders of the Common Shares of certain rights or warrants to
subscribe for or purchase Common Shares at a price, or securities convertible
into Common Shares with a conversion price, less than the then current

market price of the Common Shares, or (iii) upon the distribution to holders of
the Common Shares of evidences of indebtedness or assets (excluding regular
quarterly cash dividends) or of subscription rights or warrants (other than
those referred to above).

        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 Common Shares will be issued and, in lieu
thereof, an adjustment in cash will be made based on the market price of the
Common Shares on the last trading day prior to the date of exercise.

        At any time prior to the earlier to occur of (i) a person becoming an
Acquiring Person or (ii) the expiration of the Rights, the Corporation may
redeem the Rights in whole, but not in part, at a price of $.01 per Right (the
"Redemption Price"), which redemption shall be effective at such time, on such
basis and with such conditions as the Board of Directors may establish in its
sole discretion. The Corporation may, at its option, pay the Redemption Price in
Common Shares.

        All of the provisions of the Rights Agreement may be amended by the
Board of Directors prior to the Distribution Date. After the Distribution Date,
the provisions of the Rights Agreement may be amended by the Board in order to
cure any ambiguity, defect or inconsistency, to make changes which do not
adversely affect the interests of holders of Rights (excluding the interests of
any Acquiring Person), or, subject to certain limitations, to shorten or
lengthen any time period under the Rights Agreement.

        Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Corporation, including, without limitation, the
right to vote or to receive dividends. While the distribution of the Rights will
not be taxable to stockholders of the Corporation, stockholders may, depending
upon the circumstances, recognize taxable income should the Rights become
exercisable or upon the occurrence of certain events thereafter.

        The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group that attempts to acquire the Company
on terms not approved by the Board of Directors, except pursuant to an offer
conditioned on a substantial number of Rights being acquired. The Rights should
not interfere with any merger or other business combination approved by the
Board of Directors, as the Rights may be redeemed by the Corporation at $.01 per
Right prior to the time that a person or group has acquired beneficial ownership
of 15% or more of the Common Shares.

        The Rights Agreement, dated as of September 16, 1996, between the
Corporation and American Stock Transfer & Trust Company, as Rights Agent,
specifying the terms of the Rights is attached hereto as an exhibit and is
incorporated herein by reference. The foregoing description of the Rights is
qualified in its entirety by reference to such exhibit.

                                RIGHTS AGREEMENT

               RIGHTS AGREEMENT, dated as of September 16, 1996 (the
"Agreement"), between Celgene Corporation, a Delaware corporation (the
"Corporation") and American Stock Transfer & Trust Company (the "Rights Agent").

               The Board of Directors of the Corporation has authorized and
declared a dividend of one right (a "Right") for each Common Share (as
hereinafter defined) of the Corporation outstanding at the close of business on
September 26, 1996 (the "Record Date"), each Right representing the right to
purchase one one-tenth of a Common Share, upon the terms and subject to the
conditions herein set forth, and has further authorized and directed the
issuance of one Right with respect to each Common Share that shall become
outstanding between the Record Date and the earliest of the Distribution Date,
the Redemption Date or Final Expiration Date (as such terms are hereinafter
defined); provided, however, that Rights may be issued with respect to Common
Shares that shall become outstanding after the Distribution Date and prior to
the earlier of the Redemption Date and the Final Expiration Date in accordance
with the provisions of Section 22 of this Agreement.

               Accordingly, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:

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

               (a) "Acquiring Person" shall mean any Person who or which,
together with all Affiliates and Associates of such Person, shall be the
Beneficial Owner of 15% or more of the then outstanding Common Shares (other
than as a result of a Permitted Offer (as hereinafter defined)) or 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 then outstanding
Common Shares. Notwithstanding the foregoing, (A) the term "Acquiring Person"
shall not include (i) the Corporation, (ii) any Subsidiary of the Corporation,
(iii) any employee benefit plan of the Corporation or of any Subsidiary of the
Corporation, or (iv) any Person or entity organized, appointed or established by
the Corporation for or pursuant to the terms of any such plan, and (B) no Person
shall become an "Acquiring Person":

                      (i) as a result of the acquisition of Common Shares by the
Corporation which, by reducing the number of Common Shares outstanding,
increases the proportional number of shares beneficially owned by such Person
together with all Affiliates and Associates of such Person; provided that if (1)
a Person would be or become an Acquiring Person (but for the operation of this
subclause (i)) as a result of the acquisition of Common Shares by the
Corporation, and (2) after such share acquisition by the Corporation, such
Person, or an Affiliate or Associate of such Person, becomes the Beneficial
Owner of any additional Common Shares, then such Person shall be deemed an
Acquiring Person; or

                      (ii) if the Board of Directors determines in good faith
that a Person who would otherwise be an "Acquiring Person" has become such
inadvertently, and such Person (A) does not attempt to exercise any control over
the business affairs or management of the Corporation, including by means of a
proxy solicitation, and (B) divests as promptly as practicable a sufficient
number of Common Shares so that such Person would no longer be an "Acquiring
Person", then such Person shall not be deemed an "Acquiring Person" for any
purposes of this Agreement.

               (b) "Act" shall mean the Securities Act of 1933, as amended and
as in effect on the date of this Agreement.

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

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

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

                      (ii) which such Person or any of such Person's Affiliates
or Associates has (A) the right to acquire (whether such right is exercisable
immediately or only after the passage of time) pursuant to any agreement,
arrangement or understanding, 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, securities tendered pursuant to a tender or
exchange offer made by or on behalf of such Person or any of such Person's
Affiliates or Associates until such tendered securities are accepted for
purchase or exchange; or (B) the right to vote pursuant to any agreement,
arrangement or understanding; provided, however, that a Person shall not be
deemed the Beneficial Owner of, or to beneficially own, any security if the
agreement, arrangement or understanding to vote such security (1) arises solely
from a revocable proxy or consent given to such Person in response to a public
proxy or consent solicitation made pursuant to, and in accordance with, the
applicable rules and regulations promulgated under the Exchange Act and (2) is
not also then reportable on Schedule 13D under the Exchange Act (or any
comparable or successor report); or

                      (iii) which are beneficially owned, directly or
indirectly, by any other Person (or any Affiliate or Associate thereof) with
which such Person (or any of such Person's Affiliates or Associates) has any
agreement, arrangement or understanding (other than customary agreements with
and between underwriters and selling group members with respect to a bona fide
public offering of securities) relating to the acquisition, holding, voting
(except to the extent contemplated by the proviso to Section 1(d)(ii)(B)) or
disposing of any securities of the Corporation.

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 Right Certificates) and not by
separate Right Certificates, and (y) the right to receive Rights Certificates
will be transferable only in connection with the transfer of the underlying
Common Shares (including a transfer to the Corporation); provided, however, that
if a tender offer is terminated prior to the occurrence of a Distribution Date,
then no Distribution Date shall occur as a result of such tender offer. As soon
as practicable after the Distribution Date, the Corporation will prepare and
execute, the Rights Agent will countersign and the Corporation will send or
cause to be sent by first-class, postage-prepaid mail, to each record holder of
Common Shares as of the close of business on the Distribution Date, at the
address of such holder shown on the records of the Corporation, a Right
Certificate, substantially in the form of Exhibit A hereto (a "Right
Certificate"), evidencing one Right for each Common Share so held. As of and
after the Distribution Date, the Rights will be evidenced solely by such Right
Certificates.

               (b) As promptly as practicable following the Record Date, the
Corporation will send a copy of a Summary of Rights to Purchase Common Shares in
the form of Exhibit B hereto (the "Summary of Rights"), by first-class,
postage-prepaid mail, to each record holder of Common Shares as of the close of
business on the Record Date, at the address of such holder shown on the records
of the Corporation. With respect to certificates for Common Shares outstanding
as of the Record Date, until the Distribution Date, the Rights will be evidenced
by such certificates registered in the names of the holders thereof together
with a copy of the Summary of Rights attached thereto. Until the Distribution
Date (or the earlier of the Redemption Date or the Final Expiration Date), the
surrender for transfer of any certificate for Common Shares outstanding on the
Record Date shall also constitute the transfer of the Rights associated with
such Common Shares.

               (c) Certificates for Common Shares which become outstanding
(including, without limitation, reacquired Common Shares referred to in the last
sentence of this paragraph (c)) after the Record Date but prior to the earliest
of the Distribution Date, and the Redemption Date or the Final Expiration Date
shall be deemed also to be certificates for Rights, and shall bear the following
legend:

                      This certificate also evidences and entitles the holder
               hereof to certain rights as set forth in a Rights Agreement
               between Celgene Corporation and American Stock Transfer & Trust
               Company, dated as of September 16, 1996 (the "Rights Agreement"),
               the terms of which are hereby incorporated herein by reference
               and a copy of which is on file at the principal executive offices
               of Celgene Corporation. Under certain circumstances, as set forth
               in the Rights Agreement, such Rights will be evidenced by
               separate certificates and will no longer be evidenced by this
               certificate. Celgene Corporation will mail to the holder of this
               certificate a copy of the Rights Agreement without charge after
               receipt of a written request therefor. Under

               certain circumstances set forth in the Rights Agreement, Rights
               issued to, or held by, any Person who is, was or becomes an
               Acquiring Person or an Affiliate or Associate thereof (as defined
               in the Rights Agreement) and certain related persons, whether
               currently held by or on behalf of such Person or by any
               subsequent holder, may become null and void.

               With respect to such certificates containing the foregoing
legend, until the 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 Corporation purchases or acquires any
Common Shares after the Record Date but prior to the Distribution Date, any
Rights associated with such Common Shares shall be deemed canceled and retired
so that the Corporation shall not be entitled to exercise any Rights associated
with the Common Shares which are no longer outstanding.

               Section 4. Form of Right Certificate. (a) The Right Certificates
(and the forms of election to purchase and of assignment to be printed on the
reverse thereof) shall be substantially in the form set forth in Exhibit A
hereto and may have such marks of identification or designation and such
legends, summaries or endorsements printed thereon as the Corporation may deem
appropriate and as are not inconsistent with the provisions of this Agreement,
or as may be required to comply with any applicable law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock
exchange on which the Rights may from time to time be listed, or to conform to
usage. Subject to the provisions of Section 11 and Section 22 hereof, the Right
Certificates shall entitle the holders thereof to purchase such number of tenths
of a Common Share as shall be set forth therein at the price per Common Share
set forth therein (the "Purchase Price"), but the amount and type of securities
purchasable upon the exercise of each Right and the Purchase Price thereof shall
be subject to adjustment as provided herein.

               (b) Any Right Certificate issued pursuant to Section 3(a) or
Section 22 hereof that represents Rights which are null and void pursuant to
Section 7(e) of this Agreement and any Right Certificate issued pursuant to
Section 6 or Section 11 hereof upon transfer, exchange, replacement or
adjustment of any other Right Certificate referred to in this sentence, shall
contain (to the extent feasible) the following legend:

                      The Rights represented by this Right Certificate are or
               were beneficially owned by a Person who was or became an
               Acquiring Person or an Affiliate or Associate of an Acquiring
               Person (as such terms are defined in the Rights Agreement).
               Accordingly, this Right Certificate and the Rights represented
               hereby are null and void.

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

               Section 5. Countersignature and Registration. The Right
Certificates shall be executed on behalf of the Corporation by its Chairman of
the Board, its Chief Executive Officer, its President, any of its Vice
Presidents, or its Treasurer, either manually or by facsimile signature, shall
have affixed thereto the Corporation's seal or a facsimile thereof, and shall be
attested by the Secretary or an Assistant Secretary of the Corporation, either
manually or by facsimile signature. The Right Certificates shall be
countersigned by the Rights Agent and shall not be valid for any purpose unless
so countersigned. In case any officer of the Corporation who shall have signed
any of the Right Certificates shall cease to be such officer of the Corporation
before countersignature by the Rights Agent and issuance and delivery by the
Corporation, such Right Certificates may nevertheless be countersigned by the
Rights Agent and issued and delivered by the Corporation with the same force and
effect as though the person who signed such Right Certificates had not ceased to
be such officer of the Corporation; and any Right Certificate may be signed on
behalf of the Corporation by any person who, at the actual date of the execution
of such Right Certificate, shall be a proper officer of the Corporation to sign
such Right 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 as the appropriate place for
surrender of such Right Certificate or transfer, books for registration and
transfer of the Right Certificates issued hereunder. Such books shall show the
names and addresses of the respective holders of the Right Certificates, the
number of Rights evidenced on its face by each of the Right Certificates and the
certificate number and the date of each of the Right Certificates.

               Section 6. Transfer, Split-up, Combination and Exchange of Right
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificate. Subject to
the provisions of Section 4(b), Section 7(e) and Section 14 hereof, at any time
after the close of business on the Distribution Date, and at or prior to the
close of business on the earlier of the Redemption Date or the Final Expiration
Date, any Right Certificate or Right Certificates may be transferred, split up,
combined or exchanged for another Right Certificate or Right Certificates,
entitling the registered holder to purchase a like number of Common Shares (or,
following a Section 13 Event, other securities, as the case may be) as the Right
Certificate or Right Certificates surrendered then entitled such holder (or
former holder in the case of a transfer) to purchase. Any registered holder
desiring to transfer, split up, combine or exchange any Right Certificate or
Right Certificates shall make such request in writing delivered to the Rights
Agent, and shall surrender the Right Certificate or Right Certificates to be
transferred, split up, combined or exchanged at the office of the Rights Agent
designated for such purpose. Neither the Rights Agent nor the Corporation shall
be obligated to take any action whatsoever with respect to the transfer of any
such surrendered Right Certificate until the registered holder shall have
completed and signed the certificate contained in the form of assignment on the
reverse side of such Right Certificate and shall have provided such additional
evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or

Affiliates or Associates thereof as the Corporation shall reasonably request.
Thereupon the Rights Agent shall, subject to Section 4(b), Section 7(e)
and Section 14 hereof, countersign and deliver to the Person entitled
thereto a Right Certificate or Right Certificates, as the case may be,
as so requested. The Corporation 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 Right Certificates.

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

               Section 7. Exercise of Rights; Purchase Price; Expiration Date of
Rights. (a) Subject to Section 7(e) hereof, the registered holder of any Right
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 the Right Certificate, with the form of election to purchase
and the certificate on the reverse side thereof duly executed, to the Rights
Agent at the principal office or offices of the Rights Agent designated for such
purpose, together with payment of the aggregate Purchase Price for the total
number of Common Shares (or other securities, as the case may be) as to which
such surrendered Rights are exercised, at or prior to the earliest of (i) the
close of business on September 15, 2006 (the "Final Expiration Date"), or (ii)
the time at which the Rights are redeemed as provided in Section 23 hereof (the
"Redemption Date").

               (b) The purchase price (the "Purchase Price") per whole Common
Share at which a holder of Rights may purchase Common Shares or (subject to
Section 14 hereof) fractions thereof upon exercise of such Rights shall
initially be $100.00, shall be subject to adjustment from time to time as
provided in Sections 11 and 13(a) hereof, and shall be payable in accordance
with paragraph (c) below.

               (c) Upon receipt of a Right Certificate representing exercisable
Rights, with the form of election to purchase and the certificate duly executed,
accompanied by payment of the Purchase Price for the Common Shares (or other
securities, as the case may be) to be purchased and an amount equal to any
applicable transfer tax required to be paid by the holder of such Right
Certificate in accordance with Section 6 hereof by certified check, cashier's
check or money order payable to the order of the Corporation, the Rights Agent
shall thereupon promptly (i) (A) requisition from any transfer agent of the
Common Shares certificates for the number of Common Shares to be purchased and
the Corporation hereby irrevocably authorizes its transfer agent to comply with
all such requests, or (B) if the Corporation, in its sole discretion, shall have
elected to deposit the Common Shares issuable upon exercise of the Rights
hereunder into a depositary, requisition from the depositary agent 

                                                       
                                                                  

                                        8

depositary receipts representing such number of Common Shares as are to be
purchased (in which case certificates for the Common Shares represented
by such receipts shall be deposited by the transfer agent with the
depositary agent) and the Corporation will direct the depositary agent
to comply with such requests, (ii) when appropriate, requisition from
the Corporation the amount of cash to be paid in lieu of issuance of
fractional shares in accordance with Section 14 hereof, (iii) after receipt
of such certificates or depositary receipts, cause the same to be delivered
to or upon the order of the registered holder of such Right Certificate,
registered in such name or names as may be designated by such holder, and
(iv) when appropriate, after receipt thereof, deliver such cash to or upon
the order of the registered holder of such Right Certificate. In the event that
the Corporation is obligated to issue other securities of the Corporation
pursuant to Section 11(a) hereof, the Corporation will make all arrangements
necessary so that such other securities are available for distribution by the
Rights Agent, if and when appropriate.

               In addition, in the case of an exercise of the Rights by a holder
pursuant to Section 11(a)(ii), the Rights Agent shall return such Right
Certificate to the registered holder thereof after imprinting, stamping or
otherwise indicating thereon that the rights represented by such Right
Certificate no longer include the rights provided by Section 11(a)(ii) of the
Rights Agreement and if less than all the Rights represented by such Right
Certificate were so exercised, the Rights Agent shall indicate on the Right
Certificate the number of Rights represented thereby which continue to include
the rights provided by Section 11(a)(ii).

               (d) In case the registered holder of any Right Certificate shall
exercise less than all the Rights evidenced thereby, a new Right Certificate
evidencing Rights equivalent to the Rights remaining unexercised shall be issued
by the Rights Agent to the registered holder of such Right Certificate or to his
duly authorized assigns, subject to the provisions of Section 14 hereof, or the
Rights Agent shall place an appropriate notation on the Right Certificate with
respect to those Rights exercised.

               (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 an Affiliate or Associate of an
Acquiring Person, (ii) a transferee of an Acquiring Person (or of any Affiliate
or Associate thereof) who becomes a transferee after the Acquiring Person
becomes such, or (iii) a transferee of an Acquiring Person (or of any Affiliate
or Associate thereof) who becomes a transferee prior to or concurrently with the
Acquiring Person becoming such and receives such Rights pursuant to either (A) a
transfer (whether or not for consideration) from the Acquiring Person to holders
of equity interests in such Acquiring Person or to any Person with whom the
Acquiring Person has a continuing agreement, arrangement or understanding
regarding the transferred Rights or (B) a transfer which the Board of Directors
has determined is part of a plan, arrangement or understanding which has as a
primary purpose or effect the avoidance of this Section 7(e), shall become null
and void without any further action and no holder of such Rights shall have any
rights whatsoever with respect to such Rights, whether under any provision of
this Agreement or otherwise. The Corporation shall use all reasonable efforts to
insure that the provisions of this Section 7(e) and Section 4(b) hereof are
complied with, but shall have no liability to any

holder of Right Certificates or other Person as a result of its failure to make
any determinations with respect to an Acquiring Person or its Affiliates,
Associates or transferees hereunder.

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

               Section 8. Cancellation and Destruction of Right Certificates.
All Right Certificates surrendered for the purpose of exercise (other than an
exercise pursuant to Section 11(a)(ii)), transfer, split up, combination or
exchange shall, if surrendered to the Corporation or to any of its agents, be
delivered to the Rights Agent for cancellation or in canceled form, or, if
surrendered to the Rights Agent, shall be canceled by it, and no Right
Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this Rights Agreement. The Corporation shall deliver
to the Rights Agent for cancellation and retirement, and the Rights Agent
shall so cancel and retire, any other Right Certificate purchased or acquired
by the Corporation otherwise than upon the exercise thereof. The Rights Agent
shall deliver all canceled Right Certificates to the Corporation, or shall, at
the written request of the Corporation, destroy such canceled Right
Certificates, and in such case shall deliver a certificate of destruction
thereof to the Corporation.

               Section 9. Reservation and Availability of Common Shares. The
Corporation covenants and agrees that at all times after the occurrence of a
Section 11(a)(ii) Event it will, to the extent reasonably practicable, cause to
be reserved and kept available out of its authorized and unissued Common Shares
(and/or other securities), or any authorized and issued Common Shares (and/or
other securities) held in its treasury, the number of Common Shares (or other
securities, as the case may be) that will be sufficient to permit the exercise
in full of all outstanding Rights pursuant to this Agreement.

               So long as the Common Shares (or other securities, as the case
may be) issuable upon the exercise of the Rights may be listed on any national
securities exchange, or admitted for quotation on any on a quotation system
sponsored by a registrant national securities association, the Corporation shall
use its best efforts to cause, from and after such time as the Rights become
exercisable, all shares reserved for such issuance to be listed on such exchange
or admitted for quotation on such system, as the case may be upon official
notice of issuance upon such exercise.

               The Corporation covenants and agrees that it will take all such
action as may be necessary to ensure that all Common Shares (or other
securities, as the case may be) delivered upon exercise of Rights shall, at the
time of delivery of the certificates for such

shares or other securities (subject to payment of the Purchase Price), be duly
and validly authorized and issued and fully paid and non-assessable shares or
securities.

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

               The Corporation shall use its best efforts to (i) file, as soon
as practicable following the Shares Acquisition Date (or, if required by law, at
such earlier time following the Distribution Date as so required), a
registration statement under the 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 Act and the rules and regulations
thereunder) until the date of the expiration of the rights provided by Section
11(a)(ii). The Corporation will also take such action as may be appropriate
under the blue sky laws of the various states.

               Section 10. Common Shares Record Date. Each Person in whose name
any certificate for Common Shares (or other securities, as the case may be) is
issued upon the exercise of Rights shall for all purposes be deemed to have
become the holder of record of the Common Shares (or other securities, as the
case may be) represented thereby on, and such certificate shall be dated, the
date upon which the Right 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 Common Shares (or other securities, as the case
may be) transfer books of the Corporation 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 Common Shares (or
other securities, as the case may be) transfer books of the Corporation are
open.

               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.

               (a)(i) In the event the Corporation shall at any time after the
date of this Agreement (A) declare a dividend on the Common Shares payable in
Common Shares, (B) subdivide the outstanding Common Shares, (C) combine the
outstanding Common Shares into a smaller number of Common Shares or (D) issue
any shares of its capital stock in a reclassification of the Common Shares
(including any such reclassification in connection with a consolidation or
merger in which the Corporation is the continuing or surviving corporation),
except as otherwise provided in this Section 11(a) and Section 7(e) hereof, (x)
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
(y) 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 Common Shares transfer books of the Corporation 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 any Rights be less than the aggregate par value of
the shares of capital stock of the Corporation issuable upon exercise of such
Rights. Notwithstanding anything to the contrary in the preceding sentence, in
the event that any time after the date of this Agreement and prior to the
Distribution Date the Corporation shall take any action described in clause (A),
(B) or (C) of the preceding sentence, then in any such case no adjustment shall
be made pursuant to the immediately preceding sentence and (i) the number of
Common Shares receivable after such event upon exercise of any Right shall be
adjusted by multiplying the number of Common Shares so receivable immediately
prior to such event by a fraction, the numerator of which shall be the number of
Common Shares outstanding immediately prior to such event and the denominator of
which shall be the number of Common Shares outstanding immediately after such
event (except that in the case of the declaration of a stock dividend the
denominator shall be the number of shares outstanding immediately after payment
of such dividend, excluding any shares issued after the record date other than
in connection with such dividend), and (ii) each Common Share outstanding
immediately after such event shall have associated with respect to it that
number of Rights that each Common Share outstanding immediately prior to such
event had associated with respect to it. If an event occurs which would require
an adjustment under both 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). If an event
occurs which would require an adjustment under both 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) In the event any Person, alone or together with its
Affiliates and Associates, shall become an Acquiring Person, then proper
provision shall be made so that each holder of a Right (except as provided below
and in Section 7(e) hereof) thereafter be entitled to receive, upon exercise
thereof at a price equal to the then current Purchase Price for a whole Common
Share, in accordance with the terms of this Agreement, such number of Common
Shares as shall equal the result obtained by (x) multiplying the then current
Purchase Price per whole Common Share by the number of one-tenths of a Common
Share

for which a Right was exercisable immediately prior to the first occurrence of a
Section 11(a)(ii) Event (e.g., if a Right was exercisable immediately prior to a
Section 11(a)(ii) Event for two one-tenths of a share of Common Stock and the
Purchase Price per whole Common Share was $[X], the product would be [2X]), and
dividing that product by (y) 50% of the then current per share market price of
the Common Shares (determined pursuant to Section 11(d) hereof) on the date of
such first occurrence (such number of shares being referred to as 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 Corporation's certificate of incorporation but not
outstanding or reserved for issuance for purposes other than upon exercise of
the Rights are not sufficient to permit the exercise in full of the Rights in
accordance with the foregoing Section 11(a)(ii), the Corporation shall (A)
determine the excess of (1) the value of the Adjustment Shares based on the
"current per share market price" determined pursuant to Section 11(d) (the
"Current Value") over (2) the Purchase Price (such excess being hereinafter
referred to as the "Spread"), and (B) in respect of 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)
other equity securities of the Corporation (including, without limitation,
shares, or units of shares, of preferred stock that the Board of Directors of
the Corporation has determined to have the same value as the Common Shares (such
shares of preferred stock being referred to herein as "common share
equivalents")), (4) debt securities of the Corporation, (5) other assets or (6)
any combination of the foregoing, having an aggregate value equal to the Current
Value, where such aggregate value has been determined by the Board of Directors
of the Corporation based upon the advice of a nationally recognized investment
banking firm selected by the Board of Directors of the Corporation; provided,
however, that if the Corporation shall not have made adequate provision to
deliver value pursuant to clause (B) above within 30 days following the first
occurrence of a Section 11(a)(ii) Event, then the Corporation 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, if
necessary, cash, that in the aggregate are equal to the Spread. If the Board of
Directors of the Corporation shall determine in good faith that it is likely
that sufficient additional shares of Common Shares could be authorized for
issuance upon exercise in full of the Rights, the 30-day period set forth above
may be extended to the extent necessary, but not to more then 120 days following
the first occurrence of a Section 11(a)(ii) Trigger Date so that Corporation may
seek stockholder approval for the authorization of such additional shares of
Common Shares (such period, as it may be extended, being hereinafter referred to
as the "Substitution Period"). To the extent the Corporation determines that
some action need be taken pursuant to the first and/or second sentences of this
Section 11(a) (iii), the Corporation (x) shall provide, subject to Section 7(e)
hereof, that such action shall apply uniformly to all outstanding Rights and (y)
may suspend the exercisability of the Rights until the expiration of the
Substitution Period to seek any authorization of additional Common Shares and/or
to decide the appropriate form of distribution to be made pursuant to such first

                                       13

sentence and to determine the value thereof. In the event of any such
suspension, the Corporation shall deliver notice to the Rights Agent and issue a
public announcement stating that the exercisability of the Rights has been
temporarily suspended, as well as notice to the Rights Agent and a public
announcement at such time as the suspension is no longer in effect. For purposes
of this Section 11(a)(iii), the value of the Common Shares shall be the current
market price (as determined pursuant to Section 11(d) hereof) per Common Share
on the date of the first occurrence of a Section 11(a)(ii) Trigger Date
and the value of any common share equivalent shall be deemed to have the
same value as a Common Share on such date.

               (b) In case the Corporation shall fix a record date for the
issuance of rights (other than the Rights), options or warrants to all holders
of Common Shares entitling them (for a period expiring within 45 calendar days
after such record date) to subscribe for or purchase Common Shares (or shares
having the same rights and privileges as the Common Shares ("equivalent common
shares")) or securities convertible into Common Shares or equivalent common
shares at a price per Common Share or equivalent common share (or having a
conversion price per share, if a security convertible into Common Shares or
equivalent common shares) less than the then current per share market price of
the Common Shares (as determined pursuant to Section 11(d) hereof) 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 Common
Shares outstanding on such record date plus the number of Common Shares which
the aggregate offering price of the total number of Common Shares and/or
equivalent common 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 per share market price, and the denominator of which shall be
the number of Common Shares outstanding on such record date plus the number of
additional Common Shares and/or equivalent common 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 Rights be less than the
aggregate par value of the shares of capital stock of the Corporation issuable
upon exercise of such Rights. 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 determined in good faith by the Board of
Directors, whose determination shall be described in a statement filed with the
Rights Agent and shall be binding on the Rights Agent. Common Shares owned by or
held for the account of the Corporation shall not be deemed outstanding for the
purpose of any such computation. Such adjustment shall be made successively
whenever such a record date is fixed; and in the event that such rights, options
or warrants are not so issued, the Purchase Price shall be adjusted to be the
Purchase Price which would then be in effect if such record date had not been
fixed.

               (c) In case the Corporation shall fix a record date for the
making of a distribution to all holders of the Common Shares (including any such
distribution made in connection with a consolidation or merger in which the
Corporation is the continuing or surviving corporation) of evidences of
indebtedness or assets (other than a regular quarterly


                                       14


<PAGE>
<PAGE>


cash dividend or a dividend payable in Common 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 (as determined pursuant to Section 11(d) hereof) of the Common Shares on
such record date, less the fair market value (as determined in good faith by the
Board of Directors, whose determination shall be described in a statement filed
with the Rights Agent and shall be binding on the Rights Agent) of the portion
of the assets or evidences of indebtedness so to be distributed or of such
subscription rights or warrants applicable to one Common Share and the
denominator of which shall be such current per share market price of the Common
Shares; provided, however, that in no event shall the consideration to be paid
upon the exercise of any Rights be less than the aggregate par value of the
shares of capital stock of the Corporation to be issued upon exercise of such
Rights. 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) For the purpose of any computation hereunder, the "current
per share market price" of any security (a "Security" for the purpose of this
Section 11(d)), including, without limitation the Common Shares, on any date
shall be deemed to be the average of the daily closing prices per share of such
Security for the thirty (30) consecutive Trading Days (as such term is
hereinafter defined) immediately prior to such date; 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 thirty (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 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 the National Association of Securities
Dealers, Inc. Automated Quotations System ("NASDAQ") or such other system then
in use, or, if on any such date the Security is not quoted by any such
organization, the average of the closing bid and asked prices as furnished by a
professional market maker making a market in the Security selected by the Board
of Directors. If on any such date no such market maker is making a market in the
Security, the fair value of the Security on such date as determined in good
faith by the Board of Directors

                                       15

shall be used. The term "Trading Day" shall mean a day on which the principal
national securities exchange on which the Security is listed or admitted to
trading is open for the transaction of business or, if the Security is not
listed or admitted to trading on any national securities exchange, a Business
Day.

               (e) Notwithstanding anything herein to the contrary (except the
last sentence of this Section 11(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
ten-thousandth of a Common Share or 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 be made no later than the earlier of (i) three
(3) years from the date of the transaction which mandates such adjustment or
(ii) the Final Expiration Date.

               (f) If as a result of an adjustment made pursuant to Section
11(a)(i) or 13(a) hereof, the holder of any Right thereafter exercised shall
become entitled to receive any shares of capital stock of the Corporation other
than Common Shares, thereafter the number of 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 Common Shares contained in Section 11(a) through (c), inclusive,
and the provisions of Sections 7, 9, 10, 13 and 14 with respect to the Common
Shares shall apply on like terms to any such other shares.

               (g) All Rights originally issued by the Corporation subsequent to
any adjustment made to the Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase Price, the number of Common Shares
purchasable from time to time hereunder upon exercise of the Rights, all subject
to further adjustment as provided herein.

               (h) Unless the Corporation 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
Common Shares (calculated to the nearest ten-thousandth of a Common Share)
obtained by (i) multiplying (x) the number of Common Shares covered by a Right
immediately prior to this adjustment by (y) the Purchase Price in effect
immediately prior to such adjustment of the Purchase Price and (ii) dividing the
product so obtained by the Purchase Price in effect immediately after such
adjustment of the Purchase Price.

               (i) The Corporation may elect on or after the date of any
adjustment of the Purchase Price to adjust the number of Rights, in lieu of any
adjustment in the number of Common Shares purchasable upon the exercise of a
Right. Each of the Rights outstanding after such adjustment of the number of
Rights shall be exercisable for the number of Common Shares for which a Right
was exercisable immediately prior to such adjustment. Each Right          
                                                                  

                                       16

held of record prior to such adjustment of the number of Rights shall become
that number of Rights (calculated to the nearest ten- thousandth) obtained by
dividing the Purchase Price in effect immediately prior to the adjustment of the
Purchase Price by the Purchase Price in effect immediately after adjustment of
the Purchase Price. The Corporation shall make a public announcement of its
election to adjust the number of Rights, indicating the record date for the
adjustment, and, if known at the time, the amount of the adjustment to be made.
This record date may be the date on which the Purchase Price is adjusted or any
day thereafter, but, if the Right Certificates have been issued, shall be at
least ten (10) days later than the date of the public announcement. If Right
Certificates have been issued, upon each adjustment of the number of Rights
pursuant to this Section 11(i), the Corporation shall, as promptly as
practicable, cause to be distributed to holders of record of Right Certificates
on such record date Right Certificates evidencing, subject to Section 14 hereof,
the additional Rights to which such holders shall be entitled as a result of
such adjustment, or, at the option of the Corporation, 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 Corporation, new Right Certificates
evidencing all the Rights to which such holders shall be entitled after such
adjustment. Right Certificates so to be distributed shall be issued, executed
and countersigned in the manner provided for herein and shall be registered in
the names of the holders of record of Right 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 Common Shares issuable upon the exercise of the Rights,
the Right Certificates theretofore and thereafter issued may continue to express
the Purchase Price and the number of Common Shares which were expressed in the
initial Right Certificates issued hereunder.

               (k) Before taking any action that would cause an adjustment
reducing the Purchase Price below the aggregate par value, if any, of the number
of Common Shares or other securities issuable in respect of the Purchase Price
upon exercise of a Right, the Corporation shall take any corporate action which
may, in the opinion of its counsel, be necessary in order that the Corporation
may validly and legally issue such number of fully paid and non-assessable
Common Shares or other securities 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 Corporation may elect to defer until the occurrence of such
event the issuance to the holder of any Right exercised after such record date
the Common Shares or other securities of the Corporation, if any, issuable upon
such exercise over and above the Common Shares or other securities of the
Corporation, if any, issuable upon exercise on the basis of the Purchase Price
in effect prior to such adjustment; provided, however, the Corporation 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) Notwithstanding anything in this Section 11 to the contrary,
the Corporation shall be entitled to make such reductions in the Purchase Price,
in addition to

those adjustment 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 (i)
any consolidation or subdivision of the Common Shares, (ii) issuance wholly for
cash of Common Shares at less than the current market price, (iii) issuance
wholly for cash of Common Shares or securities which by their terms are
convertible into or exchangeable for Common Shares, (iv) stock dividends, or (v)
issuance of rights, options or warrants referred to in this Section 11,
hereafter made by the Corporation to holders of its Common Shares shall not be
taxable to such shareholders.

               (n) The Corporation covenants and agrees that it shall not, at
any time after the Distribution Date, (i) consolidate with any other Person
(other than a Subsidiary of the Corporation in a transaction which does not
violate Section 11(o) hereof), (ii) merge with or into any other Person (other
than a Subsidiary of the Corporation in a transaction which does not violate
Section 11(o) hereof), or (iii) sell or transfer (or permit any Subsidiary to
sell or transfer), in one transaction, or a series of related transactions,
assets or earning power aggregating more than 50% of the assets or earning power
of the Corporation and its Subsidiaries (taken as a whole) to any other Person
or Persons (other than the Corporation and/or of its Subsidiaries in one or more
transactions each of which does not violate Section 11(o) hereof), if (x) at the
time of or immediately after such consolidation, merger, sale or transfer there
are any charter or by-law provisions or any rights, warrants or other
instruments or securities outstanding or agreements in effect or other actions
taken, which would materially diminish or otherwise eliminate the benefits
intended to be afforded by the Rights or (y) prior to, simultaneously with or
immediately after such consolidation, merger or sale, the shareholders of the
Person who constitutes, or would constitute, the "Principal Party" for purposes
of Section 13(a) hereof shall have received a distribution of Rights previously
owned by such Person or any of its Affiliates and Associates. The Corporation
shall not consummate any such consolidation, merger, sale or transfer unless
prior thereto the Corporation and such other Person shall have executed and
delivered to the Rights Agent a supplemental agreement evidencing compliance
with this Section 11(n).

               (o) The Corporation covenants and agrees that, after the
Distribution Date, it will not, except as permitted by Section 23 or Section 27
hereof, take (or permit any Subsidiary to take) any action the purpose of which
is to, or if at the time such action is taken it is reasonably foreseeable that
the effect of such action is to materially diminish or otherwise eliminate the
benefits intended to be afforded by the Rights.

               (p) The exercise of Rights under Section 11(a)(ii) shall only
result in the loss of rights under Section 11(a)(ii) to the extent so exercised
and shall not otherwise affect the rights represented by the Rights under this
Rights Agreement, including the rights represented by Section 13.

               Section 12. Certificate of Adjusted Purchase Price or Number of
Shares. Whenever an adjustment is made as provided in Section 11 or 13 hereof,
the Corporation 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 a copy of such certificate and (c) mail a brief summary thereof

to each holder of a Right Certificate in accordance with Section 26 hereof,
provided, however, that in the event that at any time prior to the Distribution
Date the Company shall take any action described in clause (A), (B) or (C) of
Section 11(a)(i), then the Company shall not be required to satisfy the
obligations set forth in clauses (a), (b) and (c) above. The Rights Agent shall
be fully protected in relying on any such certificate and on any adjustment
therein contained and shall not be deemed to have knowledge of such adjustment
unless and until it shall have received such certificate. Notwithstanding
anything in the foregoing to the contrary, prior to the earlier to occur of the
Distribution Date and the Share Acquisition Date, the Company may, in its
discretion, satisfy the obligation set forth in clause (c) above by including
such summary in its next regular report to shareholders.

               Section 13. Consolidation, Merger or Sale or Transfer of Assets
or Earning Power. (a) In the event that, on or following the Shares Acquisition
Date, directly or indirectly, (x) the Corporation shall consolidate with, or
merge with and into, any Person, (y) the Corporation shall consolidate with, or
merge with, any Person, and the Corporation shall be the continuing or surviving
corporation of such consolidation or merger (other than, in a case of any
transaction described in (x) or (y), a merger or consolidation which would
result in all of the securities generally entitled to vote in the election of
directors ("voting securities") of the Corporation outstanding immediately prior
thereto continuing to represent (either by remaining outstanding or by being
converted into securities of the surviving entity) all of the voting securities
of the Corporation or such surviving entity outstanding immediately after such
merger or consolidation and the holders of such securities not having changed as
a result of such merger or consolidation), or (z) the Corporation shall sell or
otherwise transfer (or one or more of its Subsidiaries shall sell or otherwise
transfer), in one transaction or a series of related transactions, assets or
earning power aggregating more than 50% of the assets or earning power of the
Corporation and its Subsidiaries (taken as a whole) to any Person (other than
the Corporation or any Subsidiary of the Corporation in one or more transactions
each of which does not violate Section 11(o) hereof), then, and in each such
case, proper provision shall be made so that (i) each holder of a Right, except
as provided in Section 7(e) hereof, shall thereafter have the right to receive,
upon the exercise thereof at a price equal to the then current Purchase Price
for a whole Common Share, in accordance with the terms of this Agreement and in
lieu of Common Shares, such number of freely tradeable Common Shares of the
Principal Party (as hereinafter defined), not subject to any liens,
encumbrances, rights of first refusal or other adverse claims, as shall equal
the result obtained by (A) multiplying the then current Purchase Price for a
whole Common Share by the number of one-tenths of a Common Share for which a
Right is then exercisable (without taking into account any adjustment previously
made pursuant to Section 11(a)(ii)) and dividing that product by (B) 50% of the
then 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 Section 13 Event, all the obligations and
duties of the Corporation pursuant to this Agreement; (iii) the term
"Corporation" shall thereafter be deemed to refer to such Principal Party, it
being specifically intended that the provisions of Section 11 hereof shall apply
only to such Principal Party following the first occurrence of a Section 13
Event; 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 connection with the
consummation of any such transaction as may be necessary to assure that the
provisions hereof shall thereafter be applicable, as nearly as reasonably may
be, in relation to 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 clause (x)
or (y) of the first sentence of Section 13(a), the Person that is the issuer of
any securities into which Common Shares of the Corporation are converted in such
merger or consolidation, and if no securities are so issued, the Person that is
the other party to such merger or consolidation (including, if applicable, the
Corporation if it is the surviving corporation); and

                      (ii) in the case of any transaction described in clause
(z) of the first sentence of Section 13(a), the Person that is the party
receiving the greatest portion of the assets or earning power transferred
pursuant to such transaction or transactions; provided, however, that in any of
the foregoing cases, (1) if the Common Shares of such Person are not at such
time and have not been continuously over the preceding twelve (12) month period
registered under Section 12 of the Exchange Act, and such Person is a direct or
indirect Subsidiary of another Person the Common Shares of which are and have
been so registered, "Principal Party" shall refer to such other Person; (2) in
case such Person is a Subsidiary, directly or indirectly, 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 (1) 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
13 in the same ratio as their direct or indirect interests in such Person bear
to the total of such interests.

               (c) The Corporation shall not consummate any such consolidation,
merger, sale or transfer unless the Principal Party shall have a sufficient
number of its authorized Common Shares which 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 Corporation and such Principal
Party 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 consolidation, merger, sale or transfer mentioned in paragraph (a) of this
Section 13, the Principal Party at its own expense shall:

                      (i) prepare and file a registration statement under the
Act with respect to the Rights and the securities purchasable upon exercise of
the Rights on an appropriate form, and use its best efforts to cause such
registration statement to (A) become 

                                                       
                                                                  

                                       20

effective as soon as practicable after such filing and (B) remain effective
(with a prospectus at all times meeting the requirements of the Act) until the
Final Expiration Date;

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

                      (iii) deliver to holders of the Rights historical
financial statements for the Principal Party which comply in all 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. The rights
under this Section 13 shall be in addition to the rights to exercise Rights and
adjustments under Section 11(a)(ii) and shall survive any exercise thereof.

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

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

               (b) The Corporation 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
Corporation shall pay to the registered holders of Right 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 Common Share. For the purposes
of this Section 14(b), the current market value of a Common Share shall be the
closing price of a Common Share (as determined pursuant to Section 11(d) hereof)
for the Trading Day immediately prior to the date of such exercise.

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

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

               Section 16. Agreement of Right Holders. Every holder of a Right,
by accepting the same, consents and agrees with the Corporation 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 Right Certificates are
transferable only on the registry books of the Rights Agent if surrendered at
the principal office or offices of                              
                                                                  

                                       22

the Rights Agent designated for such purpose, duly endorsed or accompanied by a
proper instrument of transfer and with the appropriate form fully executed;

               (c) subject to Section 6 and Section 7(f) hereof, the Corporation
and the Rights Agent may deem and treat the person in whose name the Right
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
Right Certificate or the associated Common Shares certificate made by anyone
other than the Corporation or the Rights Agent) for all purposes whatsoever, and
neither the Corporation nor the Rights Agent, subject to the last sentence of
Section 7(e) hereof, shall be required to be affected by any notice to the
contrary; and

               (d) notwithstanding anything in this Agreement to the contrary,
neither the Corporation 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 Corporation must use its best efforts to have any such
order, decree or ruling lifted or otherwise overturned as soon as possible.

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

               Section 18. Concerning the Rights Agent. The Corporation 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 it duties hereunder. The Corporation also agrees to indemnify the Rights
Agent for, and to hold it harmless against, any loss, liability, or expense,
incurred without negligence, bad faith or willful misconduct on the part of the
Rights Agent, for anything done or omitted by the Rights Agent in connection
with the acceptance and administration of this Agreement, including the costs
and expenses of defending against any
                                                       
                                                                  

                                       23

claim of liability in the premises. In no event shall the Rights Agent be liable
for special, indirect or consequential loss or damage of any kind whatsoever
(including but not limited to lost profits), even if the Rights Agent has been
advised of the likelihood of such loss or damage and regardless of the form of
action. The indemnity provided for herein shall survive the expiration of the
Rights, the resignation or removal of the Rights Agent and the termination of
this Agreement.

               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 Right
Certificate delivered to the Rights Agent pursuant to Sections 6 and 7 of this
certificate for Common Shares or for other securities of the Corporation,
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 19. 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 all or substantially all of the corporate trust business of the
Rights Agent or any successor Rights Agent, shall be the successor to the Rights
Agent under this Agreement without the execution or filing of any paper or any
further act on the part of any of the parties hereto, provided that such
corporation would be eligible for appointment as a successor Rights Agent under
the provisions of Section 21 hereof. In case at the time such successor Rights
Agent shall succeed to the agency created by this Agreement, any of the Right
Certificates shall have been countersigned but not delivered, any such successor
Rights Agent may adopt the countersignature of a predecessor Rights Agent and
deliver such Right Certificates so countersigned; and in case at that time any
of the Right Certificates shall not have been countersigned, any successor
Rights Agent may countersign such Right Certificates either in the name of the
predecessor or in the name of the successor Rights Agent; and in all such cases
such Right Certificates shall have the full force provided in the Right
Certificates and in this Agreement.

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

               Section 20. Duties of Rights Agent. The Rights Agent undertakes
only those duties and obligations imposed by this Agreement upon the following
terms and conditions,

by all of which the Corporation and the holders of Right Certificates, by their
acceptance thereof, shall be bound:

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

               (b) Whenever in the performance of its duties under this
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter (including, without limitation, the identity of an Acquiring Person and
the determination of the current market price of any Security) be proved or
established by the Corporation prior to taking or suffering any action
hereunder, such fact or matter (unless other evidence in respect thereof be
herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by any one of the Chairman of the Board, the
Chief Executive Officer, the President, any Vice President, the Treasurer or the
Secretary of the Corporation 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 only for its own
negligence, bad faith or willful misconduct.

               (d) The Rights Agent shall not be liable for or by reason of any
of the statements of fact or recitals contained in this Agreement or in the
Right Certificates (except its countersignature on such Right Certificates) or
be required to verify the same, but all such statements and recitals are and
shall be deemed to have been made by the Corporation 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 Right Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Corporation of any
covenant or condition contained in this Agreement or in any Rights Certificate;
nor shall it be responsible for any change in the exercisability of the Rights
(including the Rights becoming void pursuant to Section 7(e) hereof) or any
adjustment required under the provisions of Section 11 or Section 13 hereof or
responsible for the manner, method or amount of any such 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 Right Certificates
after receipt of the certificate described in Section 12 hereof); nor shall it
by any act hereunder be deemed to make any representation or warranty as to the
authorization or reservation of any Common Shares to be issued pursuant to this
Agreement or any Right Certificate or as to whether any Common Shares will, when
issued, be validly authorized and issued, fully paid and non-assessable.

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

               (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from any
one of the Chairman of the Board, the Chief Executive Officer, the President,
any Vice President, the Treasurer of the Secretary of the Corporation, and to
apply to such officers for advice or instructions in connection with its duties,
and shall not be liable for any action taken or suffered by it in good faith or
lack of action 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 Corporation 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 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 Corporation
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 instruction in response to such application
specifying the action to be taken or omitted.

               (h) The Rights Agent and any shareholder, director, officer or
employee of the Rights Agent may buy, sell or deal in any of the Rights or other
securities of the Corporation or become pecuniarily interested in any
transaction in which the Corporation may be interested, or contract with or lend
money to the Corporation 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 Corporation 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 Corporation resulting from any such act,
default, neglect or misconduct, provided reasonable care was exercised in the
selection and continued employment thereof.

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

               (k) If, with respect to any Rights Certificate surrendered to the
Rights Agent for exercise or transfer, the certificate attached to the form of
assignment or form of election to purchase, as the case may be, has not been
completed, the Rights Agent shall not take any further action with respect to
such requested exercise of transfer without first consulting with the
Corporation.

               Section 21. Change of Rights Agent. The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon thirty (30) days' notice in writing mailed to the Corporation and
to the transfer agent of the Common Shares by registered or certified mail, and,
subsequent to the Distribution Date, to the holders of the Right Certificates by
first-class mail. The Corporation may remove the Rights Agent or any successor
Rights Agent upon sixty (60) days' notice in writing, mailed to the Rights Agent
or any successor Rights Agent, as the case may be, and to the transfer agent of
the Common Shares by registered or certified mail, and, subsequent to the
Distribution Date, to holders of the Right Certificates by first-class mail. If
the Rights Agent shall resign or be removed or shall otherwise become incapable
of acting, the Corporation shall appoint a successor to the Rights Agent. If the
Corporation shall fail to make such appointment within a period of thirty (30)
days after giving notice of such removal or after it has been notified in
writing of such resignation or incapacity by the resigning or incapacitated
Rights Agent or by the holder of a Right Certificate (who shall, with such
notice, submit his Right Certificate for inspection by the Corporation), then
the registered holder of any Right 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 Corporation or by such a court, shall be
a corporation organized and doing business under the laws of the United States
or of the State of New York (or of any other state of the United States so long
as such corporation is authorized to do business as a banking institution in the
State of New York), in good standing, having an office in the State of New York,
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 $50,000,000. 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
Corporation shall file notice thereof in writing with the predecessor Rights
Agent and the transfer agent of the Common Shares, and, subsequent to the
Distribution Date, mail a notice thereof in writing to the registered holders of
the Right Certificates. Failure to give any notice provided for in this Section
21, however, or any defect therein, shall not affect the legality or validity of
the resignation or removal of the successor Rights Agent or the appointment of
the Rights Agent, as the case may be.

               Section 22. Issuance of New Right Certificates. Notwithstanding
any of the provisions of this Agreement or of the Rights to the contrary, the
Corporation may, at its option, issue new Right Certificates evidencing Rights
in such form as may be approved by

the 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 upon exercise of the Rights made in accordance with the provisions
of this Agreement.

               In addition, in connection with the issuance or sale of Common
Shares following the Distribution Date and prior to the earlier of the
Redemption Date and the Final Expiration Date, the Corporation (a) shall with
respect to Common Shares so issued or sold pursuant to the exercise of stock
options or under any employee plan or arrangement, or upon the exercise,
conversion or exchange of securities, notes or debentures issued by the
Corporation, and (b) may, in any other case, if deemed necessary or appropriate
by the Board of Directors, issue Right Certificates representing the appropriate
number of Rights in connection with such issuance of sale, provided, however,
that (i) the Corporation shall not be obligated to issue any such Right
Certificates if, and to the extent that, the Corporation shall be advised by
counsel that such issuance would create a significant risk of material adverse
tax consequences to the Corporation or the Person to whom such Right Certificate
would be issued, and (ii) no Right Certificate shall be issued if, and to the
extent that, appropriate adjustment shall otherwise have been made in lieu of
the issuance thereof.

               Section 23. Redemption and Termination. (a) The Board of
Directors may, at its option, redeem all but not less than all the then
outstanding Rights at a redemption price of $0.01 per Right, as such amount may
be 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"), at any time prior to the
earlier of (x) the time that any Person becomes an Acquiring Person, or (y) the
Final Expiration Date. The Corporation may, at its option, pay the Redemption
Price either in Common Shares (based on the "current per share market price," as
defined in Section 11(d) hereof, of the Common Shares at the time of redemption)
or cash; provided that if the Corporation elects to pay the Redemption Price in
Common Shares, the Corporation shall not be required to issue any fractional
Common Shares and the number of Common Shares issuable to each holder of Rights
shall be rounded down to the next whole share. 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.

               (b) Immediately upon the action of the Board of Directors of the
Company ordering the redemption of the Rights pursuant to paragraph (a) of this
Section 23, 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 for each Right so held. The
Corporation shall promptly give notice of any such redemption to the Rights
Agent and the holders of Rights in the manner set forth in Section 26, provided,
however, that the failure to give, or any defect in, any such notice shall not
affect the validity of such redemption. Any notice which is mailed in the manner
herein provided shall be deemed given, whether or not the holder receives the
notice. Each such notice of redemption will state the method by which the
payment of the Redemption Price will be made. Neither the Corporation nor any of
its Affiliates or Associates may redeem, acquire or purchase for value any
Rights at any time in any manner other than that

specifically set forth in this Section 23 and other than in connection with the
purchase of Common Shares prior to the Distribution Date.

               Section 24. Exchange. (a) Subject to Section 24(d), the Board of
Directors may, at its option, at any time after the time that any Person becomes
an Acquiring Person, 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) and Section 11(a)(ii) hereof) for
Common Shares of the Corporation at an exchange ratio of one Common Share (or a
lesser ratio as determined by the Board of Directors, if the Corporation does
not have sufficient authorized and unreserved Common Shares) per Right,
appropriately adjusted to reflect any stock split, stock dividend or similar
transaction occurring after the date hereof (such exchange ratio being
hereinafter referred to as the "Exchange Ratio"). Notwithstanding the foregoing,
the Board of Directors shall not be empowered to effect such exchange at any
time after any Person (other than the Corporation, any Subsidiary of the
Corporation, any employee benefit plan of the Corporation or any such
Subsidiary, any entity holding Common Shares for or pursuant to the terms of any
such plan or any trustee, administrator or fiduciary of such a plan), together
with all Affiliates and Associates of such Person, becomes the Beneficial Owner
of 50% or more of the Common Shares then outstanding.

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

               (c) In the event that there shall not be sufficient Common Shares
issued but not outstanding or authorized but unissued (and not reserved for
issuance other than upon exercise of the Rights) to permit any exchange of
Rights as contemplated in accordance with this Section 24, the (i) Corporation
shall take all such action as may be necessary to authorize additional Common
Shares for issuance upon exchange of the Rights, or (ii) the Board of Directors
may determine to exchange Common Shares for then outstanding and exercisable
Rights at such exchange ratio of less than one Common Share per Right,
appropriately adjusted as set forth in Section 24(a) above, so that all (and not
less than all) Common Shares
                                                       
                                                                  

                                       29

issued but not outstanding or authorized but unissued (and not reserved for
issuance other than upon exercise of the Rights) are issued in the exchange
contemplated by this Section 24.

               (d) In any exchange pursuant to this Section 24, the Corporation,
at its option, may substitute common stock equivalents (as defined in Section
11(a)(iii)) for shares of Common Stock exchangeable for Rights, at the initial
rate of one common stock equivalent for each share of Common Stock, as
appropriately adjusted to reflect adjustments in dividend liquidation and voting
rights of common stock equivalents pursuant to the terms thereof, so that each
common stock equivalent delivered in lieu of each share of Common Stock shall
have essentially the same dividend, liquidation and voting rights as one share
of Common Stock.

               Section 25. Notice of Certain Events. (a) In case the Corporation
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 Common Shares or to make any
other distribution to the holders of its Common Shares (other than a regular
quarterly cash dividend), (ii) to offer to the holders of its Common Shares
rights or warrants to subscribe for or to purchase any additional Common Shares
or shares of stock of any class or any other securities, rights or options,
(iii) to effect any reclassification of its Common Shares (other than a
reclassification involving only the subdivision of outstanding Common Shares),
(iv) to effect any consolidation or merger into or with any other Person (other
than a Subsidiary of the Corporation in a transaction which does not violate
Section 11(o) hereof), 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 Corporation
and its Subsidiaries (taken as a whole) to any other Person or Persons (other
than the Corporation and/or any of its Subsidiaries in one or more transactions
each of which does not violate Section 11(o) hereof), or (v) to effect the
liquidation, dissolution or winding up of the Corporation, then, in each such
case, the Corporation shall give to each holder of the Right Certificate, in
accordance with Section 26 hereof, a notice of such proposed action to the
extent feasible and file a certificate with the Rights Agent to that effect,
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, 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 twenty (20)
days prior to the record date for determining holders of the Common Shares for
purposes of such action, and in the case of any such other action, at least
twenty (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, whichever
shall be the earlier.

               (b) Notwithstanding anything in this Agreement to the contrary,
prior to the Distribution Date a filing by the Corporation with the Securities
and Exchange Commission shall constitute sufficient notice to the holders of the
securities of the Corporation, including the Rights, for purposes of this
Agreement and no other notice need be given to such holders.

               (c) If a Triggering Event shall occur, then (i) the Corporation
shall as soon as practicable thereafter give to each holder of a Right
Certificate, in accordance with Section 26 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) or Section 13 hereof, as the
case may be, and (ii) all references in the preceding paragraph (a) to Common
Shares shall be deemed thereafter to refer also, if appropriate, to capital
stock equivalents, as provided for in Section 11(a)(iii).

               Section 26. Notices. Notices or demands authorized by this
Agreement to be given or made by the Rights Agent or by the holder of any Right
Certificate to or on the Corporation shall be sufficiently given or made if sent
by first-class mail, postage prepaid, addressed (until another address is filed
in writing with the Rights Agent) as follows:

               Subject to the provisions of Section 21 hereof, any notice or
demand authorized by this Agreement to be given or made by the Corporation or by
the holder of any Right Certificate to or on the Rights Agent shall be

               New York, NY
               Attention:  President

Notices or demands authorized by this Agreement to be given or made by the
Corporation or the Rights Agent to the holder of any Right Certificate or, if
prior to the Distribution Date, to the holder of certificates representing
Common Shares, shall be sufficiently given or made if sent by first-class mail,
postage prepaid, addressed to such holder at the address of such holder as shown
on the registry books of the Corporation.

               Section 27. Supplements and Amendments. Prior to the Distribution
Date, the Corporation and the Rights Agent shall, if the Board of Directors 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, the Corporation and the Rights Agent shall, if the
Board of Directors so directs, supplement or amend this Agreement without the
approval of any holders of Right 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 or (iv) to change or supplement
the provisions hereunder in any manner which the

Board of Directors may deem necessary or desirable and which shall not adversely
effect the interests of the holders of Right Certificates (other than an
Acquiring Person or an Affiliate or Associate of an Acquiring Person); provided,
however, that this Agreement may not be supplemented or amended to lengthen,
pursuant to clause (iii) of this sentence, (A) a time period relating to when
the Rights may be redeemed at such time as the Rights are not then redeemable;
or (B) any other time period unless such lengthening is for the purpose of
protecting, enhancing or clarifying the rights of, and/or the benefits to, the
holders of Rights. Upon the delivery of a certificate from an appropriate
officer of the Corporation which states that the proposed supplement or
amendment is in compliance with the terms of this Section 27, the Rights Agent
shall execute such supplement or amendment, provided that such supplement or
amendment does not adversely affect the rights or obligations of the Rights
Agent under Section 18 or Section 20 of this Agreement. Prior to the
Distribution Date, the interests of the holders of Rights shall be deemed
coincident with the interests of the holders of Common Shares.

               Section 28. Determination and Actions by the Board of Directors
of the Corporation, etc. The Board of Directors shall have the exclusive power
and authority to administer this Agreement and to exercise all rights and powers
specifically granted to the Board of Directors, or the Corporation, 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, without limitation, a
determination to redeem or not redeem the Rights or to amend the Agreement and
whether any proposed amendment adversely affects the interests of the holders of
Right Certificates). For all purposes of this Agreement, any calculation of the
number of Common Shares or other securities 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)(1)(i) of the General Rules and Regulations under the Exchange Act as in
effect on the date of this Agreement. All such actions, calculations,
interpretations and determinations (including, for purposes of clause (y) below,
all omissions with respect to the foregoing) which are done or made by the Board
of Directors in good faith, shall (x) be final, conclusive and binding on the
Corporation, the Rights Agent, the holders of the Right Certificates and all
other parties, and (y) not subject the Board to any liability to the holders of
the Right Certificates.

               Section 29. Successors. All the covenants and provisions of this
Agreement by or for the benefit of the Corporation or the Rights Agents shall
bind and inure to the benefit of their respective successors and assigns
hereunder.

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


                                                       
                                                                  

                                       32

and the registered holders of the Right Certificates (and, prior to the
Distribution Date, the Common Shares).

               Section 31. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.

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

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

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

               outstanding Rights at a redemption price of $.01 per Right
               (subject to adjustment); or

                      (b) at any time after the time that any Person becomes an
               Acquiring Person (but before such Person, together with all
               Affiliates and Associates of such Person, becomes the Beneficial
               Owner of 50% or more of the Common Shares then outstanding),
               exchange all or part of the then outstanding Rights (other than
               Rights held by the Acquiring Person and certain related Persons)
               for Common Shares at an exchange ratio of one Common Share per
               Right (subject to adjustment).

                      SUMMARY OF RIGHTS TO PURCHASE SHARES

               On September 16, 1996, the Board of Directors of Celgene
Corporation (the "Corporation") declared a dividend distribution of one right (a
"Right") to purchase one one-tenth of a share of the Common Stock, $.01 par
value, of the Corporation (the "Common Shares") for each outstanding share of
Common Stock, payable to the stockholders of record on September 16, 1996 (the
"Record Date"). The Board of Directors also authorized and directed the issuance
of one Right with respect to each Common Share issued thereafter until the
Distribution Date (as defined below) and, in certain circumstances, with respect
to Common Shares issued after the Distribution Date. Except as set forth below,
each Right, when it becomes exercisable, entitles the registered holder to
purchase from the Corporation one one-tenth of a Common Share at a price of
$100.00 per whole Common 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 Corporation and American Stock Transfer & Trust
Company, as Rights Agent (the "Rights Agent"), dated as of September 16, 1996.

               Initially, the Rights will be attached to all certificates
representing Common Shares then outstanding, and no separate Right Certificates
will be distributed. The Rights will separate from the Common Shares upon the
earliest to occur of (i) a person or group of affiliated or associated persons
having acquired beneficial ownership of 15% or more of the outstanding Common
Shares (except pursuant to a Permitted Offer, as hereinafter defined); or (ii)
10 days (or such later date as the Board of Directors may determine) following
the commencement of, or announcement of an intention to make, a tender offer or
exchange offer the consummation of which would result in a person or group
becoming an Acquiring Person (as hereinafter defined) (the earliest of such
dates being called the "Distribution Date"). A person or group whose acquisition
of Common Shares causes a Distribution Date pursuant to clause (i) above is an
"Acquiring Person." The date that a person or group becomes an Acquiring Person
is the "Shares Acquisition Date." A person who acquires Common Shares pursuant
to a tender or exchange offer which is for all outstanding Common Shares at a
price and on terms which a majority of the Board of Directors determines (prior
to acquisition) to be adequate and in the best interests of the Corporation and
its stockholders (other than such person, its affiliates and associates) (a
"Permitted Offer") will not be deemed to be an Acquiring Person and such
person's ownership will not constitute a Distribution Date.

               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 the transfer or new
issuance of Common Shares will contain a notation incorporating the Rights
Agreement by reference. Until the Distribution Date (or earlier 
                                                       
                                                                  

                                       B-1

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 ("Right
Certificates") will be mailed to holders of record of the Common Shares as of
the close of business on the Distribution Date (and to each initial record
holder of certain Common Shares issued after the Distribution Date), and such
separate Right Certificates alone will evidence the Rights.

               The Rights are not exercisable until the Distribution Date, and
will expire at the close of business on September 15, 2006, unless earlier
redeemed by the Corporation as described below.

               In the event that any person becomes an Acquiring Person, each
holder of Rights (other than Rights that have become void as described below)
will thereafter have the right (the "Flip-In Right") to receive, upon exercise
of such Rights, the number of Common Shares (or, in certain circumstances, other
securities of the Corporation) having a value (immediately prior to such
triggering event) equal to two times the aggregate exercise price of such
Rights. The Board, at its option, may exchange each Right (other than those that
have become void as described below) for one Common Share in lieu of the Flip-In
Right, provided no person is the beneficial owner of 50% or more of the Common
Shares at the time of such exchange. Notwithstanding the foregoing, following
the occurrence of the event described above, all Rights that are or (under
certain circumstances specified in the Rights Agreement) were beneficially owned
by any Acquiring Person or any affiliate or associate thereof will be null and
void.

               In the event that, at any time following the Shares Acquisition
Date, (i) the Corporation is acquired in a merger or other business combination
transaction in which the holders of all of the outstanding Common Shares
immediately prior to the consummation of the transaction are not the holders of
all of the surviving corporation's voting power, or (ii) more than 50% of the
Corporation's assets or earning power is sold or transferred, then each holder
of Rights (except Rights which previously have been voided as set forth above)
shall thereafter have the right (the "Flip-Over Right") to receive, upon
exercise of such Rights, common shares of the acquiring company having a value
equal to two times the aggregate exercise price of the Rights; provided,
however, that the Flip Over Right shall not apply to any transaction described
in clause (i) if (x) such transaction is with a person or persons (or a wholly
owned subsidiary of any such person or persons) that acquired Common Shares
pursuant to a Permitted Offer and (y) the price and form of consideration

offered in such transaction is the same as that paid to all holders of Common
Shares whose shares were purchased to the Permitted Offer. The holder of a Right
will continue to have the Flip-Over Right whether or not such holder exercises
or surrenders the Flip-In Right.

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

                                       B-2

prevent dilution (i) in the event of a stock dividend on, or a subdivision,
combination or reclassification of, the Common Shares, (ii) upon the grant
to holders of the Common Shares of certain rights or warrants to subscribe
for or purchase Common Shares at a price, or securities convertible
into Common Shares with a conversion price, less than the then current market
price of the Common Shares, or (iii) upon the distribution to holders of the
Common Shares of evidences of indebtedness or assets (excluding regular
quarterly cash dividends) or of subscription rights or warrants (other than
those referred to above).

               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 Common Shares will be issued and, in lieu
thereof, an adjustment in cash will be made based on the market price of the
Common Shares on the last trading day prior to the date of exercise.

               At any time prior to the earlier to occur of (i) a person
becoming an Acquiring Person or (ii) the expiration of the Rights, the
Corporation may redeem the Rights in whole, but not in part, at a price of $.01
per Right (the "Redemption Price"), which redemption shall be effective at such
time, on such basis and with such conditions as the Board of Directors may
establish in its sole discretion. The Corporation may, at its option, pay the
Redemption Price in Common Shares.

               All of the provisions of the Rights Agreement may be amended by
the Board of Directors prior to the Distribution Date. After the Distribution
Date, the provisions of the Rights Agreement may be amended by the Board in
order to cure any ambiguity, defect or inconsistency, to make changes which do
not adversely affect the interests of holders of Rights (excluding the interests
of any Acquiring Person), or, subject to certain limitations, to shorten or
lengthen any time period under the Rights Agreement.

               Until a Right is exercised, the holder thereof, as such, will
have no rights as a stockholder of the Corporation, including, without
limitation, the right to vote or to receive dividends. While the distribution of
the Rights will not be taxable to stockholders of the Corporation, stockholders
may, depending upon the circumstances, recognize taxable income should the
Rights become exercisable or upon the occurrence of certain events thereafter.
