     Rights Agreement, dated as of October 7, 1998, between Bio-Technology
General Corp., a Delaware corporation (the "Company"), and American Stock
Transfer & Trust Company (the "Rights Agent").

     The Board of Directors of the Company has authorized and declared a
dividend of one preferred share purchase right (a "Right") for each Common Share
(as hereinafter defined) of the Company outstanding at the Close of Business (as
hereinafter defined) on October 22, 1998 (the "Record Date"), each Right
representing the right to purchase one one-thousandth (1/1000) of a Preferred
Share (as hereinafter defined), 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
and the Final Expiration Date (as such terms are hereinafter defined).

     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 Rights Agreement, the
following terms have the meanings indicated:

     (a) "Acquiring Person" shall mean any Person (as such term is hereinafter
defined) who or which, together with all Affiliates and Associates (as such
terms are hereinafter defined) of such Person, shall be the Beneficial Owner (as
such term is hereinafter defined) of 20% or more of the Common Shares of the
Company then outstanding, but shall not include the Company, any Subsidiary (as
such term is hereinafter defined) of the Company, any employee benefit plan of
the Company or any Subsidiary of the Company, or any entity holding Common
Shares for or pursuant to the terms of any such plan. Notwithstanding the
foregoing, no Person shall become an "Acquiring Person" as the result of an
acquisition of Common Shares by the Company which, by reducing the number of
shares outstanding, increases the proportionate number of shares beneficially
owned by such Person to 20% or more of the Common Shares of the Company then
outstanding; provided, however, that if a Person shall become the Beneficial
Owner of 20% or more of the Common Shares of the Company then outstanding by
reason of share purchases by the Company and shall, after such share purchases
by the Company, become the Beneficial Owner of any additional Common Shares of
the Company, then such Person shall be deemed to be an "Acquiring Person."
Notwithstanding the foregoing, if the Board of Directors of the Company
determines in good faith that a Person who would otherwise be an "Acquiring
Person," as defined pursuant to the foregoing provisions of this paragraph (a),
has become such inadvertently, and such Person divests as promptly as
practicable a sufficient number of Common Shares so that such Person would no
longer be an "Acquiring Person," as defined pursuant to the foregoing provisions
of this paragraph (a), then such Person shall not be deemed to be an "Acquiring
Person" for any purposes of this Rights Agreement.


                                      -1-



     (b) "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 Rights Agreement.

     (c) 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, within the meaning of Rule 13d-3
     of the General Rules and Regulations under the Exchange Act as in effect on
     the date of this Rights Agreement;

          (ii) which such Person or any of such Person's Affiliates or
     Associates has (A) the right to acquire (whether such right is exercisable
     immediately or only after the passage of time) pursuant to any agreement,
     arrangement or understanding (other than customary agreements with and
     between underwriters and selling group members with respect to a bona fide
     public offering of securities), or upon the exercise of conversion rights,
     exchange rights, rights (other than these Rights), warrants or options, or
     otherwise; provided, however, that a Person shall not be deemed the
     Beneficial Owner of, or to beneficially own, (1) securities tendered
     pursuant to a tender or exchange offer made by or on behalf of such Person
     or any of such Person's Affiliates or Associates until such tendered
     securities are accepted for purchase or exchange, or (2) securities which a
     Person or any of such Person's Affiliates or Associates may be deemed to
     have the right to acquire pursuant to any merger or other acquisition
     agreement between the Company and such Person (or one or more of its
     Affiliates or Associates) if such agreement has been approved by the Board
     of Directors of the Company prior to there being an Acquiring Person; or
     (B) the right to vote pursuant to any agreement, arrangement or
     understanding; provided, however, that a Person shall not be deemed the
     Beneficial Owner of, or to beneficially own, any security pursuant to under
     this Section 1(c)(ii)(B) if the agreement, arrangement or understanding to
     vote such security (1) arises solely from a revocable proxy or consent
     given to such Person in response to a public proxy or consent solicitation
     made pursuant to, and in accordance with, the applicable rules and
     regulations 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 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) for the
     purpose of acquiring, holding, voting (except to the extent contemplated by
     the proviso to Section 1(c)(ii)(B)) or disposing of any securities of the
     Company;


                                      -2-



provided, however, that in no case shall an officer or director of the Company
be deemed (x) the Beneficial Owner of any securities beneficially owned by
another officer or director of the Company solely by reason of actions
undertaken by such persons in their capacity as officers or directors of the
Company or (y) the Beneficial Owner of securities held of record by the trustee
of any employee benefit plan of the Company or any Subsidiary of the Company for
the benefit of any employee of the Company or any Subsidiary of the Company,
other than the officer or director, by reason of any influence that such officer
or director may have over the voting of the securities held in the plan.

     Notwithstanding anything in this definition of Beneficial Ownership to the
contrary, the phrase "then outstanding," when used with reference to a Person's
Beneficial Ownership of securities of the Company, shall mean the number of such
securities then issued and outstanding together with the number of such
securities not then actually issued and outstanding which such Person would be
deemed to own beneficially hereunder.

     (d) "Business Day" shall mean any day other than a Saturday, a Sunday or a
day on which banking institutions in New York are authorized or obligated by law
or executive order to close.

     (e) "Close of Business" on any given date shall mean 5:00 P.M., New York
time, on such date; provided, however, that if such date is not a Business Day
it shall mean 5:00 P.M., New York time, on the next succeeding Business Day.

     (f) "Common Shares" when used with reference to the Company shall mean the
shares of common stock, par value $.01 per share, of the Company. "Common
Shares" when used with reference to any Person other than the Company shall mean
the capital stock (or equity interest) with the greatest voting power of such
other Person or, if such other Person is a Subsidiary of another Person, the
Person or Persons which ultimately control such first-mentioned Person.

     (g) "Common Stock Equivalents" shall have the meaning set forth in Section
11(a)(iii).

     (h) "Distribution Date" shall have the meaning set forth in Section 3
hereof.

     (i) "Exchange Act" shall mean the Securities Exchange Act of 1934, 
as amended.

     (j) "Final Expiration Date" shall have the meaning set forth in Section 7
hereof.

     (k) "Interested Person" with respect to a Transaction shall mean any Person
who (i) is or will become an Acquiring Person if such Transaction were to be


                                      -3-



consummated or an Affiliate or Associate of such a Person, and (ii) is, or
directly or indirectly proposed, nominated or financially supported, a director
of the Company in office at the time of consideration of such Transaction who
was elected at an annual or special meeting of stockholders.

     (l) "Person" shall mean any individual, firm, corporation, partnership or
other entity, and shall include any successor (by merger or otherwise) of such
entity.

     (m) "Preferred Shares" shall mean shares of Series A Junior Participating
Cumulative Preferred Stock, par value $.01 per share, of the Company having the
rights and preferences set forth in the Form of Certificate of Designations
attached to this Rights Agreement as Exhibit A.

     (n) "Purchase Price" with respect to each Right shall mean $45.00, as such
amount may from time to time be adjusted as provided herein, and shall be
payable in lawful money of the United States of America. All references herein
to the Purchase Price shall mean the Purchase Price as in effect at the time in
question.

     (o) "Record Date" shall have the meaning set forth in the introductory
paragraph hereof.

     (p) "Redemption Date" shall have the meaning set forth in Section 7 hereof.

     (r) "Securities Act" shall mean the Securities Act of 1933, as amended.

     (s) "Shares Acquisition Date" shall mean the first date of public
announcement (which, for purposes of this definition, shall include, without
limitation, a report filed pursuant to Section 13(d) of the Exchange Act) by the
Company or an Acquiring Person that an Acquiring Person has become such, or such
earlier date as a majority of the Board of Directors shall become aware of the
existence of the Acquiring Person; provided that, if such Person is determined
not to have become an Acquiring Person pursuant to the last sentence of
Section 1(a), then no Shares Acquisition Date shall be deemed to have occurred.

     (t) "Subsidiary" of any Person shall mean any corporation or other entity
of which a majority of the voting power of the voting equity securities or
equity interest is owned, directly or indirectly, by such Person, and any other
corporation or other entity that is otherwise controlled by such Person.

                                      -4-



     (v) "Triggering Event" shall have the meaning set forth in Section

     Section 2. Appointment of Rights Agent. The Company hereby appoints the
Rights Agent to act as agent for the Company and the holders of the Rights (who,
in accordance with Section 3 hereof, shall prior to the Distribution Date also

from time to time appoint such co-Rights Agents as it may deem necessary or
desirable.

     Section 3. Issue of Right Certificates. (a) Until the Close of Business on
the earlier of (i) the tenth day after the Shares Acquisition Date or (ii) the
tenth Business Day (or such later date as may be determined by action of the
Board of Directors prior to such time as any Person becomes an Acquiring Person)
after the date of the commencement by any Person (other than the Company, any
Subsidiary of the Company, any employee benefit plan of the Company or of any
Subsidiary of the Company or any entity holding Common Shares for or pursuant to
the terms of any such plan) of, or of the first public announcement of the
intention of any Person (other than the Company, any Subsidiary of the Company,
any employee benefit plan of the Company or of any Subsidiary of the Company or
any entity holding Common Shares for or pursuant to the terms of any such plan)
to commence, a tender or exchange offer the consummation of which would result
in any Person becoming the Beneficial Owner of Common Shares aggregating 20% or
more of the then outstanding Common Shares (including any such date which is
after the date of this Rights Agreement and prior to the issuance of the Rights;
the earlier of such dates being herein referred to as the "Distribution Date"),
(x) the Rights will 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 Right Certificates will be transferable only in connection with the
transfer of Common Shares. As soon as practicable after the Distribution Date,
the Company will prepare and execute, the Rights Agent will countersign, and the
Company will send or cause to be sent (and the Rights Agent will, if requested,
send) by first-class, insured, postage-prepaid mail, to each record holder of
Common Shares as of the close of business on the Distribution Date, at the
address of such holder shown on the records of the Company, a Right Certificate,
in substantially the form of Exhibit B hereto (a "Right Certificate"),
evidencing one Right for each Common Share so held. As of the Distribution Date,
the Rights will be evidenced solely by such Right Certificates.

     (b) On the Record Date, or as soon as practicable thereafter, the Company
will send a copy of a Summary of Rights to Purchase Preferred Shares, in
substantially the form of Exhibit C hereto (the "Summary of Rights"), by
first-class, postage-prepaid mail, to each record holder of Common Shares as of
the Close of Business on the Record Date, at the address of such holder shown on
the records of the Company. With respect to certificates for Common Shares
outstanding as of the Record Date, until the Distribution Date, the Rights will
be evidenced by such certificates 


                                      -5-



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 as of the Record Date, with or
without a copy of the Summary of Rights attached thereto, shall also constitute
the transfer of the Rights associated with the Common Shares represented
thereby.

     (c) Certificates for Common Shares which become outstanding (including,
without limitation, upon transfer of outstanding Common Shares, disposition of
Common Shares out of treasury stock or issuance or reissuance of Common Shares
out of authorized but unissued shares) after the Record Date but prior to the
earliest of the Distribution Date, the Redemption Date or the Final Expiration
Date shall have impressed on, printed on, written on or otherwise affixed to
them the following legend:

     This certificate also evidences and entitles the holder hereof to certain
     rights as set forth in a Rights Agreement between Bio-Technology General
     Corp. and American Stock Transfer & Trust Company, dated as of October 7,
     1998 (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 Bio-Technology General Corp. 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. Bio-Technology General Corp. 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, as set forth in
     the Rights Agreement, Rights issued to any Person who becomes an Acquiring
     Person (as defined in the Rights Agreement), including such Rights held by
     a 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 Company purchases or acquires any Common Shares after the
Record Date but prior to the Distribution Date, any Rights associated with such
Common Shares shall be deemed canceled and retired so that the Company shall not
be entitled to exercise any Rights associated with the Common Shares which are
no longer outstanding.

     Notwithstanding this paragraph (c), the omission of a legend shall not
affect the enforceability of any part of this Rights Agreement or the rights of
any holder of the Rights.

     Section 4. Form of Right Certificates. The Right Certificates (and the
forms of election to purchase Preferred Shares and of assignment to be printed
on the


                                      -6-



reverse thereof) shall be substantially the same as Exhibit B hereto and may
have such marks of identification or designation and such legends, summaries or
endorsements printed thereon as the Company may deem appropriate and as are not
inconsistent with the provisions of this Rights 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 one one-thousandths of a
Preferred Share as shall be set forth therein at the Purchase Price per one
one-thousandths of a Preferred Share set forth therein, but the number of such
one one-thousandths of a Preferred Share and the Purchase Price shall be subject
to adjustment as provided herein.

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

     (b) Following the Distribution Date, the Rights Agent will keep or cause to
be kept, at its principal office, 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 date of
each of the Right Certificates.

     Section 6. Transfer, Split Up, Combination and Exchange of Right
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates. (a)
Subject to the provisions of 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 (other than Right Certificates representing
Rights that have become void pursuant to Section 11(a)(ii) hereof or that have
been exchanged pursuant to Section 24 hereof) may be transferred, split up,
combined or exchanged for another Right Certificate or Right Certificates,
entitling the registered holder to purchase a like 


                                      -7-



number of one one-thousandths of a Preferred Share as the Right Certificate or
Right Certificates surrendered then entitled such holder 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 principal
office of the Rights Agent. Thereupon the Rights Agent shall countersign and
deliver to the person entitled thereto a Right Certificate or Right
Certificates, as the case may be, as so requested. The Company may require
payment of a sum sufficient to cover any tax or governmental charge that may be
imposed in connection with any transfer, split up, combination or exchange of
Right Certificates.

     (b) Upon receipt by the Company and the Rights Agent of evidence reasonably
satisfactory to them of the loss, theft, destruction or mutilation of a Right
Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to them, and, at the Company's request,
reimbursement to the Company and the Rights Agent of all reasonable expenses
incidental thereto, and upon surrender to the Rights Agent and cancellation of
the Right Certificate if mutilated, the Company will make and deliver a new
Right Certificate of like tenor to the Rights Agent for 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) Except as otherwise provided herein (including Section 11), each Right shall
entitle the registered holder thereof, upon exercise thereof as provided herein,
to purchase for the Purchase Price, at any time after the Distribution Date and
at or prior to the earliest of (i) the Close of Business on October 6, 2008 (the
"Final Expiration Date"), (ii) the time at which the Rights are redeemed as
provided in Section 23 hereof (the "Redemption Date"), or (iii) the time at
which such Rights are exchanged as provided in Section 24 hereof, one
one-thousandth of a Preferred Share, subject to adjustment from time to time as
provided herein.

     (b) Subject to Sections 23(b) and 24(b) and the second paragraph of Section
11(a)(ii), 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 on the reverse side thereof
duly executed, to the Rights Agent at the principal office of the Rights Agent
in New York, New York, together with payment of the Purchase Price for each one
one-thousandth (1/1000th) of a Preferred Share as to which the Rights are
exercised, at or prior to the Final Expiration Date.

     (c) Upon receipt of a Right Certificate representing exercisable Rights,
with the form of election to purchase duly executed, accompanied by payment of
the Purchase Price for the Preferred Shares (or fractions thereof) 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 9 hereof by
certified check, cashier's check 


                                      -8-



or money order payable to the order of the Company, the Rights Agent shall
thereupon promptly (i) (A) requisition from any transfer agent of the Preferred
Shares certificates for the number of one one-thousandths of a Preferred Share
to be purchased and the Company hereby irrevocably authorizes its transfer agent
to comply with all such requests, or (B) if the Company shall have elected to
deposit the Preferred Shares with a depositary agent under a depositary
agreement, requisition from the depositary agent depositary receipts
representing such number of one one-thousandths of a Preferred Share as are to
be purchased (in which case certificates for the Preferred Shares represented by
such receipts shall be deposited by the transfer agent with the depositary
agent) and the Company hereby directs the depositary agent to comply with such
request, (ii) when appropriate, requisition from the Company the amount of cash
to be paid in lieu of issuance of fractional shares in accordance with Section
14 hereof, (iii) after receipt of such certificates or depositary receipts,
cause the same to be delivered to or upon the order of the registered holder of
such Right Certificate, registered in such name or names as may be designated by
such holder and (iv) when appropriate, after receipt, deliver such cash to or
upon the order of the registered holder of such Right Certificate.

     (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.

     (e) Notwithstanding anything in this Rights Agreement to the contrary,
neither the Rights Agent nor the Company shall be obligated to undertake any
action with respect to a registered holder of Rights upon the occurrence of any
purported transfer or exercise of Rights pursuant to Section 6 hereof or this
Section 7 unless such registered holder shall have (i) completed and signed the
certificate contained in the form of assignment or form of election to purchase
set forth on the reverse side of the Rights Certificate surrendered for such
transfer or exercise and (ii) provided such additional evidence of the identity
of the Beneficial Owner (or former Beneficial Owner) thereof as the Company
shall reasonably request.

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


                                      -9-



     Section 9. Availability of Preferred Shares. (a) The Company covenants and
agrees that it will cause to be reserved and kept available out of its
authorized and unissued Preferred Shares, or any Preferred Shares held in its
treasury, the number of Preferred Shares that will be sufficient to permit the
exercise in full of all outstanding Rights in accordance with Section 7. The
Company covenants and agrees that it will take all such action as may be
necessary to ensure that all Preferred Shares delivered upon exercise of Rights
shall, at the time of delivery of the certificates for such Preferred Shares
(subject to payment of the Purchase Price), be duly and validly authorized and
issued and fully paid and nonassessable shares.

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

     (c) From and after such time as the Rights become exercisable, the Company
shall use its best efforts, if then necessary to permit the issuance of the
Preferred Shares upon the exercise of Rights, to register and qualify such
Preferred Shares under the Securities Act and any applicable state securities or
"Blue Sky" laws (to the extent exemptions therefrom are not available), cause
such registration statement and qualifications to become effective as soon as
possible after such filing and keep such registration and qualifications
effective until the earlier of the date as of which the Rights are no longer
exercisable for such securities and the Final Expiration Date. The Company may
temporarily suspend, for a period of time not to exceed 90 calendar days after
the Distribution Date, the exercisability of the Rights in order to prepare and
file a registration statement under the Securities Act and permit such
registration statement to become effective; provided, however, that no such
suspension shall remain effective after, and the Rights shall without any
further action by the Company or any other Person become exercisable immediately
upon, the effectiveness of such registration statement. Upon any such
suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended and shall issue a
further public announcement at such time as the suspension is no longer in
effect. Notwithstanding any provision herein to the contrary, the Rights shall
not be exercisable in any jurisdiction if the requisite qualification under the
blue sky or securities laws of such jurisdiction shall not have been obtained or
the exercise of the Rights shall not be permitted under applicable law.


                                      -10-



     (d) So long as the Preferred Shares issuable upon the exercise or exchange
of Rights are to be listed on any national securities exchange, the Company
covenants and agrees to use its best efforts to cause, from and after such time
as the Rights become exercisable or exchangeable, all Preferred Shares reserved
for such issuance to be listed on such securities exchange upon official notice
of issuance upon such exercise or exchange.

     Section 10. Preferred Shares Record Date. Each person in whose name any
certificate for Preferred Shares is issued upon the exercise of Rights shall for
all purposes be deemed to have become the holder of record of the Preferred
Shares represented thereby on, and such certificate shall be dated, the date
upon which the 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 Preferred Shares transfer books of the Company are closed, such person
shall be deemed to have become the record holder of such shares on, and such
certificate shall be dated, the next succeeding Business Day on which the
Preferred Shares transfer books of the Company are open. Prior to the exercise
of the Rights evidenced thereby, the holder of a Right Certificate shall not be
entitled to any rights of a holder of Preferred Shares for which the Rights
shall be exercisable, including, without limitation, the right to vote, to
receive dividends or other distributions or to exercise any preemptive rights,
and shall not be entitled to receive any notice of any proceedings of the
Company, except as provided herein.

     Section 11. Adjustment of Purchase Price, Number of Shares or Number of
Rights. The Purchase Price, the number of Preferred 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 Company shall at any time after the date of this
Rights Agreement (A) declare a dividend on the Preferred Shares payable in
Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine
the outstanding Preferred Shares into a smaller number of Preferred Shares or
(D) issue any shares of its capital stock in a reclassification of the Preferred
Shares (including any such reclassification in connection with a consolidation
or merger in which the Company is the continuing or surviving corporation),
except as otherwise provided in this Section 11(a), the Purchase Price in effect
at the time of the record date for such dividend or of the effective date of
such subdivision, combination or reclassification, and the number and kind of
shares of capital stock issuable on such date, shall be proportionately adjusted
so that the holder of any Right exercised after such time shall be entitled to
receive the aggregate number and kind of shares of capital stock which, if such
Right had been exercised immediately prior to such date and at a time when the
Preferred Shares transfer books of the Company were open, he 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 


                                      -11-



consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right.

     (ii) Subject to Section 24 of this Rights Agreement, in the event any
Person becomes an Acquiring Person (the first occurrence of such event being
referred to hereinafter as the "Triggering Event"), each holder of a Right shall
thereafter have a right to receive, upon exercise thereof at a price equal to
the then current Purchase Price, in accordance with the terms of this Rights
Agreement, and in lieu of Preferred Shares, such number of Common Shares as
shall equal the result obtained by (x) multiplying the then current Purchase
Price by the number of one one-thousandths (1/1000ths) of a Preferred Share for
which a Right is then exercisable and dividing that product by (y) 50% of the
then current per share market price of the Company's Common Shares (determined
pursuant to Section 11(d) hereof) on the date of the occurrence of such event.
In the event that any Person shall become an Acquiring Person and the Rights
shall then be outstanding, the Company shall not take any action which would
eliminate or diminish the benefits intended to be afforded by the Rights.

     Notwithstanding anything in this Rights Agreement to the contrary, from and
after the time any Person becomes an Acquiring Person, any Rights that are or
were acquired or Beneficially Owned by any Acquiring Person (or any Associate or
Affiliate of such Acquiring Person) shall be void and any holder of such Rights
shall thereafter have no right to exercise such Rights under any provision of
this Rights Agreement. No Right Certificate shall be issued pursuant to Section
3 that represents Rights Beneficially Owned by an Acquiring Person whose Rights
would be void pursuant to the preceding sentence or any Associate or Affiliate
thereof; no Right Certificate shall be issued at any time upon the transfer of
any Rights to an Acquiring Person whose Rights would be void pursuant to the
preceding sentence or any Associate or Affiliate thereof or to any nominee of
such Acquiring Person, Associate or Affiliate; and any Right Certificate
delivered to the Rights Agent for transfer to an Acquiring Person whose Rights
would be void pursuant to the preceding sentence shall be canceled.

     (iii) In lieu of issuing Common Shares in accordance with Section 11(a)(ii)
hereof, the Company may, if the Board of Directors determines that such action
is necessary or appropriate and not contrary to the interest of holders of
Rights (and, in the event that the number of Common Shares which are authorized
by the Company's Certificate of Incorporation but not outstanding or reserved
for issuance for purposes other than upon exercise of the Rights are not
sufficient to permit the exercise in full of the Rights, or if any necessary
regulatory approval for such issuance has not been obtained by the Company, the
Company shall): (A) determine the excess of (1) the value of the Common Shares
issuable upon the exercise of a Right (the "Current Value") over (2) the
Purchase Price (such excess, the "Spread") and (B) with respect to each Right,
make adequate provision to substitute for such Common Shares, upon exercise of
the Rights, (1) cash, (2) a reduction in the Purchase Price, (3) other equity
securities of the Company (including, without limitation, shares or fractions of


                                      -12-



shares of any series of preferred stock which the Board of Directors of the
Company has deemed to have the same value as Common Shares (such shares or
fractions of shares of preferred stock are herein called "Common Stock
Equivalents")), except to the extent that the Company has not obtained any
necessary stockholder or regulatory approval for such issuance, (4) debt
securities of the Company, except to the extent that the Company has not
obtained any necessary stockholder or regulatory approval for such issuance, (5)
other assets, or (6) any combination of the foregoing, having an aggregate value
equal to the Current Value, where such aggregate value has been determined by
the Board of Directors of the Company based upon the advice of a nationally
recognized investment banking firm selected by the Board of Directors of the
Company; provided, however, if the Company shall not have made adequate
provision to deliver value pursuant to clause (B) above within thirty (30) days
following the later of (x) the first occurrence of a Triggering Event and (y)
the date on which the Company's right of redemption pursuant to Section 23(a)
expires (the later of (x) and (y) being referred to herein as the
"Section 11(a)(ii) Trigger Date"), then the Company shall be obligated to
deliver, upon the surrender for exercise of a Right and without requiring
payment of the Purchase Price, Common Shares (to the extent available), except
to the extent that the Company has not obtained any necessary stockholder or
regulatory approval for such issuance, and then, if necessary, cash, which
shares and/or cash have an aggregate value equal to the Spread. If the Board of
Directors of the Company shall determine in good faith that it is likely that
sufficient additional Common Shares could be authorized for issuance upon
exercise in full of the Rights or that any necessary regulatory approval for
such issuance will be obtained, the thirty (30) day period set forth above may
be extended to the extent necessary, but not more than ninety (90) days after
the Section 11(a)(ii) Trigger Date, in order that the Company may seek
stockholder approval for the authorization of such additional shares or take
action to obtain such regulatory approval (such period, as it may be extended,
the "Substitution Period"). To the extent that the Company determines that some
action need be taken pursuant to the first and/or second sentences of this
Section 11(a)(iii), the Company (x) shall provide, subject to Section 11(a)(ii)
hereof and the last sentence of this Section 11(a)(iii), that such action shall
apply uniformly to all outstanding Rights and (y) may suspend the exercisability
of the Rights until the expiration of the Substitution Period in order to seek
any authorization of additional shares, to take any action to obtain any
required regulatory approval and/or to decide the appropriate form of
distribution to be made pursuant to such first sentence and to determine the
value thereof. In the event of any such suspension, the Company shall issue a
public announcement stating that the exercisability of the Rights has been
temporarily suspended, as well as a public announcement at such time as the
suspension is no longer in effect. For purposes of this Section 11(a)(iii), the
value of the Common Shares shall be the current per share market price (as
determined pursuant to Section 11(d) hereof) of the Common Shares on the
Section 11(a)(ii) Trigger Date and the value of any "Common Stock Equivalent"
shall be deemed to have the same value as the Common Shares on such date. The
Board of Directors of the Company may, but shall not be required to, establish
procedures to allocate the right to receive Common Shares upon the exercise of
the Rights among holders of Rights pursuant to this Section 11(a)(iii).


                                      -13-



     (b) In case the Company shall fix a record date for the issuance of rights,
options or warrants to all holders of Preferred Shares entitling them (for a
period expiring within 45 calendar days after such record date) to subscribe for
or purchase Preferred Shares (or shares having the same rights, privileges and
preferences as the Preferred Shares ("equivalent preferred shares")) or
securities convertible into Preferred Shares or equivalent preferred shares at a
price per Preferred Share or equivalent preferred share (or having a conversion
price per share, if a security convertible into Preferred Shares or equivalent
preferred shares) less than the then current per share market price of the
Preferred Shares (as defined in Section 11(d)) on such record date, the Purchase
Price to be in effect after such record date shall be determined by multiplying
the Purchase Price in effect immediately prior to such record date by a
fraction, the numerator of which shall be the number of Preferred Shares
outstanding on such record date plus the number of Preferred Shares which the
aggregate offering price of the total number of Preferred Shares and/or
equivalent preferred shares so to be offered (and/or the aggregate initial
conversion price of the convertible securities so to be offered) would purchase
at such current market price and the denominator of which shall be the number of
Preferred Shares outstanding on such record date plus the number of additional
Preferred Shares and/or equivalent preferred shares to be offered for
subscription or purchase (or into which the convertible securities so to be
offered are initially convertible); provided, however, that in no event shall
the consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right. In case such subscription price may be paid in a
consideration part or all of which shall be in a form other than cash, the value
of such consideration shall be as determined in good faith by the Board of
Directors of the Company, whose determination shall be described in a statement
filed with the Rights Agent. Preferred Shares owned by or held for the account
of the Company shall not be deemed outstanding for the purpose of any such
computation. Such adjustment shall be made successively whenever such a record
date is fixed; and in the event that such rights, options or warrants are not so
issued, the Purchase Price shall be adjusted to be the Purchase Price which
would then be in effect if such record date had not been fixed.

     (c) In case the Company shall fix a record date for the making of a
distribution to all holders of the Preferred Shares (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation) of evidences of indebtedness
or assets (other than a regular quarterly cash dividend or a dividend payable in
Preferred Shares) or subscription rights or warrants (excluding those referred
to in Section 11(b) hereof), the Purchase Price to be in effect after such
record date shall be determined by multiplying the Purchase Price in effect
immediately prior to such record date by a fraction, the numerator of which
shall be the then current per share market price of the Preferred Shares on such
record date, less the fair market value (as determined in good faith by the
Board of Directors of the Company, whose determination shall be described in a
statement filed with the Rights Agent) of the portion of the assets or evidences
of indebtedness so to be distributed or of such subscription rights or warrants
applicable to one Preferred Share and the denominator of which shall be such
current per share 


                                      -14-



market price of the Preferred Shares; provided, however, that in no event shall
the consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company to be issued
upon exercise of one Right. Such adjustments shall be made successively whenever
such a record date is fixed; and in the event that such distribution is not so
made, the Purchase Price shall again be adjusted to be the Purchase Price which
would then be in effect if such record date had not been fixed.

     (d) (i) For the purpose of any computation hereunder, the "current per
share market price" of any security (a "Security" for the purpose of this
Section 11(d)(i)) on any date shall be deemed to be the average of the daily
closing prices per share of such Security for the 30 consecutive Trading Days
(as such term is hereinafter defined) immediately prior to such date; provided,
however, that in the event that the current per share market price of the
Security is determined during a period following the announcement by the issuer
of such Security of (A) a dividend or distribution on such Security payable in
shares of such Security or securities convertible into such shares, or (B) any
subdivision, combination or reclassification of such Security and prior to the
expiration of 30 Trading Days after the ex-dividend date for such dividend or
distribution, or the record date for such subdivision, combination or
reclassification, then, and in each such case, the current per share market
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 of the Company. The term "Trading Day" shall mean a day on
which the principal national securities exchange on which the Security is listed
or admitted to trading is open for the transaction of business or, if the
Security is not listed or admitted to trading on any national securities
exchange, a Business Day.

     (ii) For the purpose of any computation hereunder, the "current per share
market price" of the Preferred Shares shall be determined in accordance with the
method set forth in Section 11(d)(i). If the Preferred Shares are not publicly
traded, the "current per share market price" of the Preferred Shares shall be
conclusively deemed to be the current per share market price of the Common
Shares as determined 


                                      -15-



pursuant to Section 11(d)(i), multiplied by one thousand (appropriately adjusted
to reflect any stock split, stock dividend or similar transaction occurring
after the date hereof). If neither the Common Shares nor the Preferred Shares
are publicly held or so listed or traded, "current per share market price" shall
mean the fair value per share as determined in good faith by the Board of
Directors of the Company, whose determination shall be described in a statement
filed with the Rights Agent.

     (e) No adjustment in the Purchase Price shall be required unless such
adjustment would require an increase or decrease of at least 1% in the Purchase
Price; provided, however, that any adjustments which by reason of this Section
11(e) are not required to be made shall be carried forward and taken into
account in any subsequent adjustment. All calculations under this Section 11
shall be made to the nearest cent or to the nearest one one-millionth of a
Preferred Share or one ten-thousandth of any other share or security, as the
case may be. Notwithstanding the first sentence of this Section 11(e), any
adjustment required by this Section 11 shall be made no later than the earlier
of (i) three years from the date of the transaction which requires such
adjustment or (ii) the date of the expiration of the right to exercise any
Rights.

     (f) If as a result of an adjustment made pursuant to Section 11(a) hereof,
the holder of any Right thereafter exercised shall become entitled to receive
any shares of capital stock of the Company other than Preferred Shares,
thereafter the number of such other shares so receivable upon exercise of any
Right shall be subject to adjustment from time to time in a manner and on terms
as nearly equivalent as practicable to the provisions with respect to the
Preferred Shares contained in Section 11(a), (b), (c), (e), (h), (i) and (m) and
the provisions of Sections 7, 9, 10, 13 and 14 with respect to the Preferred
Shares shall apply on like terms to any such other shares.

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

     (h) Unless the Company shall have exercised its election as provided in
Section 11(i), upon each adjustment of the Purchase Price as a result of the
calculations made in Sections 11(b) and (c), each Right outstanding immediately
prior to the making of such adjustment shall thereafter evidence the right to
purchase, at the adjusted Purchase Price, that number of one one-thousandths of
a Preferred Share (calculated to the nearest one one-millionth of a Preferred
Share) obtained by (i) multiplying (x) the number of one one-thousandths of a
Preferred Share covered by a Right immediately prior to this adjustment by (y)
the Purchase Price in effect immediately prior to such adjustment of the
Purchase Price and (ii) dividing the product so obtained by the Purchase Price
in effect immediately after such adjustment of the Purchase Price.


                                      -16-



     (i) The Company may elect on or after the date of any adjustment of the
Purchase Price to adjust the number of Rights in substitution for any adjustment
in the number of one one-thousandths of a Preferred Share purchasable upon the
exercise of a Right. Each of the Rights outstanding after such adjustment of the
number of Rights shall be exercisable for the number of one one-thousandths of a
Preferred Share for which a Right was exercisable immediately prior to such
adjustment. Each Right held of record prior to such adjustment of the number of
Rights shall become that number of Rights (calculated to the nearest one
ten-thousandth) obtained by dividing the Purchase Price in effect immediately
prior to adjustment of the Purchase Price by the Purchase Price in effect
immediately after adjustment of the Purchase Price. The Company shall make a
public announcement of its election to adjust the number of Rights, indicating
the record date for the adjustment, and, if known at the time, the amount of the
adjustment to be made. This 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 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 Company 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 Company, shall cause to
be distributed to such holders of record in substitution and replacement for the
Right Certificates held by such holders prior to the date of adjustment, and
upon surrender thereof, if required by the Company, 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 one one-thousandths of a Preferred Share 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 one one-thousandths of
a Preferred Share 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 one one-thousandth of the then par value, if any, of the
fraction of the Preferred Shares or other shares of capital stock issuable upon
exercise of a Right, the Company shall take any corporate action which may, in
the opinion of its counsel, be necessary in order that the Company may validly
and legally issue fully paid and nonassessable Preferred Shares or other such
shares at such adjusted Purchase Price.

     (l) In any case in which this Section 11 shall require that an adjustment
in the Purchase Price be made effective as of a record date for a specified
event, the Company may elect to defer until the occurrence of such event the
issuing 


                                      -17-



to the holder of any Right exercised after such record date of the Preferred
Shares and other capital stock or securities of the Company, if any, issuable
upon such exercise over and above the Preferred Shares and other capital stock
or securities of the Company, if any, issuable upon such exercise on the basis
of the Purchase Price in effect prior to such adjustment; provided, however,
that the Company shall deliver to such holder a due bill or other appropriate
instrument evidencing such holder's right to receive such additional shares upon
the occurrence of the event requiring such adjustment.

     (m) Anything in this Section 11 to the contrary notwithstanding, the
Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that it in its sole discretion shall determine to be advisable in
order that any consolidation or subdivision of the Preferred Shares, issuance
wholly for cash of any Preferred Shares at less than the current market price,
issuance wholly for cash of Preferred Shares or securities which by their terms
are convertible into or exchangeable for Preferred Shares, dividends on
Preferred Shares payable in Preferred Shares or issuance of rights, options or
warrants referred to hereinabove in Section 11(b), hereafter made by the Company
to holders of its Preferred Shares shall not be taxable to such stockholders.

     (n) In the event that at any time after the date of this Rights Agreement
and prior to the Distribution Date, the Company shall (i) declare or pay any
dividend on the Common Shares payable in Common Shares or (ii) effect a
subdivision, combination or consolidation of the Common Shares (by
reclassification or otherwise than by payment of dividends in Common Shares)
into a greater or lesser number of Common Shares, then in any such case (A) the
number of one one-thousandths of a Preferred Share purchasable after such event
upon proper exercise of each Right shall be determined by multiplying the number
of one one-thousandths of a Preferred Share so purchasable immediately prior to
such event by a fraction, the numerator of which is the number of Common Shares
outstanding immediately before such event and the denominator of which is the
number of Common Shares outstanding immediately after such event, and (B) each
Common Share outstanding immediately after such event shall have issued with
respect to it that number of Rights which each Common Share outstanding
immediately prior to such event had issued with respect to it. The adjustments
provided for in this Section 11(n) shall be made successively whenever such a
dividend is declared or paid or such a subdivision, combination or consolidation
is effected.

     (o) Notwithstanding any other provision of this Rights Agreement, no
adjustment to the number of Preferred Shares (or fractions of a share) or other
securities for which a Right is exercisable or the number of Rights outstanding
or associated with each Common Share or any similar or other adjustment shall be
made or be effective if such adjustment would have the effect of reducing or
limiting the benefits the holders of the Rights would have had absent such
adjustment, including, 


                                      -18-



without limitation, the benefits under Sections 11 and 13, unless the terms of
this Rights Agreement are amended so as to preserve such benefits.

     (p) The Company covenants and agrees that, after the earlier of the
Distribution Date or the Shares Acquisition Date, except as permitted by
Sections 23, 24 or 27, it will not take (or permit any Subsidiary of the Company
to take) any action if at the time such action is taken it is intended or
reasonably foreseeable that such action will reduce or otherwise limit the
benefits the holders of the Rights would have had absent such action, including,
without limitation, the benefits under Sections 11 and 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
Company shall promptly (a) prepare a certificate setting forth such adjustment,
and a brief statement of the facts accounting for such adjustment, (b) file with
the Rights Agent and with each transfer agent for the Common Shares or the
Preferred Shares a copy of such certificate and (c) mail a brief summary thereof
to each holder of a Right Certificate in accordance with Section 25 hereof. 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
any such adjustment unless and until it shall have received such certificate.

     Section 13. Consolidation, Merger or Sale or Transfer of Assets or Earning
Power. (a) In the event, directly or indirectly, at any time after the
Triggering Event (i) the Company shall consolidate with or shall merge into any
other Person, (ii) any Person shall merge with and into the Company and the
Company shall be the continuing or surviving corporation of such merger and, in
connection with such merger, all or part of the Common Shares shall be changed
into or exchanged for stock or other securities of any other Person (or of the
Company) or cash or any other property, or (iii) the Company shall sell or
otherwise transfer (or one or more of its Subsidiaries shall sell or otherwise
transfer), in one or more transactions, assets or earning power aggregating 50%
or more of the assets or earning power of the Company and its Subsidiaries
(taken as a whole) to any other Person (other than the Company or one or more
wholly-owned Subsidiaries of the Company), then upon the first occurrence of
such event, proper provision shall be made so that: (A) each holder of a Right
(other than Rights which have become void pursuant to Section 11(a)(ii) hereof)
shall thereafter have the right to receive, upon the exercise thereof at the
then current Purchase Price, in accordance with the terms of this Rights
Agreement and in lieu of Preferred Shares or Common Shares of the Company, such
number of validly authorized and issued, fully paid, non-assessable and 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 dividing the then current Purchase
Price by 50% of the current per share market price of the Common Shares of such
Principal Party (determined pursuant to Section 11(d) hereof) on the date of
consummation of such consolidation, merger, sale or transfer; provided, however,
that the then current Purchase Price and the number of Common


                                      -19-



Shares of such Principal Party so receivable upon exercise of a Right shall be
subject to further adjustment as appropriate in accordance with Section 11(f)
hereof to reflect any events occurring in respect of the Common Shares of such
Principal Party after the occurrence of such consolidation, merger, sale or
transfer; (B) such Principal Party shall thereafter be liable for, and shall
assume, by virtue of such consolidation, merger, sale or transfer, all the
obligations and duties of the Company pursuant to this Rights Agreement; (C) the
term "Company" shall thereafter be deemed to refer to such Principal Party; and
(D) such Principal Party shall take such steps (including, but not limited to,
the reservation of a sufficient number of its Common Shares in accordance with
Section 9 hereof) in connection with such consummation 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; provided that, upon the
subsequent occurrence of any consolidation, merger, sale or transfer of assets
or other extraordinary transaction in respect of such Principal Party, each
holder of a Right shall thereupon be entitled to receive, upon exercise of a
Right and payment of the Purchase Price as provided in this Section 13(a), such
cash, shares, rights, warrants and other property which such holder would have
been entitled to receive had such holder, at the time of such transaction, owned
the Common Shares of the Principal Party receivable upon the exercise of a Right
pursuant to this Section 13(a), and such Principal Party shall take such steps
(including, but not limited to, reservation of shares of stock) as may be
necessary to permit the subsequent exercise of the Rights in accordance with the
terms hereof for such cash, shares, rights, warrants and other property.

          (b) "Principal Party" shall mean:

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

          (ii) in the case of any transaction described in (iii) of the first
     sentence of Section 13(a) hereof, the Person that is the party receiving
     the greatest portion of the assets or earning power transferred pursuant to
     such transaction or transactions, or, if each Person that is a party to
     such transaction or transactions receives the same portion of the assets or
     earning power so transferred or if the Person receiving the greatest
     portion of the assets or 


                                      -20-



     earning power cannot be determined, whichever of such Persons is the issuer
     of Common Shares having the greatest aggregate market value of shares
     outstanding;

provided, however, that in any such case described in the foregoing clause
(b)(i) or (b)(ii), if the Common Shares of such Person are not at such time or
have not been continuously over the preceding 12-month period registered under
Section 12 of the Exchange Act, then (1) if such Person is a direct or indirect
Subsidiary of another Person the Common Shares of which are and have been so
registered, the term "Principal Party" shall refer to such other Person, or (2)
if such Person is a Subsidiary, directly or indirectly, of more than one Person,
the Common Shares of all of which are and have been so registered, the term
"Principal Party" shall refer to whichever of such Persons is the issuer of
Common Shares having the greatest aggregate market value of shares outstanding,
or (3) if such Person is owned, directly or indirectly, by a joint venture
formed by two or more Persons that are not owned, directly or indirectly, by the
same Person, the rules set forth in clauses (1) and (2) above shall apply to
each of the owners having an interest in the venture as if the Person owned by
the joint venture was a Subsidiary of both or all of such joint venturers, and
the Principal Party in each such case shall bear the obligations set forth in
this Section 13 in the same ratio as its interest in such Person bears to the
total of such interests.

     (c) The Company shall not consummate any consolidation, merger, sale or
transfer referred to in Section 13(a) hereof unless prior thereto the Company
and the Principal Party involved therein shall have executed and delivered to
the Rights Agent an agreement confirming that the requirements of Sections 13(a)
and (b) hereof shall promptly be performed in accordance with their terms and
that such consolidation, merger, sale or transfer of assets shall not result in
a default by the Principal Party under this Rights Agreement as the same shall
have been assumed by the Principal Party pursuant to Sections 13(a) and (b)
hereof and providing that, as soon as practicable after executing such agreement
pursuant to this Section 13, the Principal Party will:

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

          (ii) use its best efforts, if the Common Shares of the Principal Party
     shall be listed or admitted to trading on the New York Stock Exchange or on
     another national securities exchange, to list or admit to trading (or
     continue the listing of) the Rights and the securities purchasable upon
     exercise of the Rights on the New York Stock Exchange or such securities
     exchange, or, if the 


                                      -21-



     Common Shares of the Principal Party shall not be listed or admitted to
     trading on the New York Stock Exchange or a national securities exchange,
     to cause the Rights and the securities receivable upon exercise of the
     Rights to be authorized for quotation on NASDAQ or on such other system
     then in use;

          (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 (or any successor form) under the Exchange Act;
     and

          (iv) obtain waivers of any rights of first refusal or preemptive
     rights in respect of the Common Shares of the Principal Party subject to
     purchase upon exercise of outstanding Rights.

     (d) In case the Principal Party has provision in any of its authorized
securities or in its certificate of incorporation or by-laws or other instrument
governing its affairs, which provisions would have the effect of (i) causing
such Principal Party to issue (other than to holders of Rights pursuant to this
Section 13), in connection with, or as a consequence of, the consummation of a
transaction referred to in this Section 13, Common Shares or Common Stock
Equivalents of such Principal Party at less than the then current market price
per share thereof (determined pursuant to Section 11(d) hereof) or securities
exercisable for, or convertible into, Common Shares or Common Stock Equivalents
of such Principal Party at less than such then current market price, or (ii)
providing for any special payment, tax or similar provision in connection with
the issuance of the Common Shares of such Principal Party pursuant to the
provisions of Section 13, then, in such event, the Company hereby agrees with
each holder of Rights that it shall not consummate any such transaction unless
prior thereto the Company and such Principal Party shall have executed and
delivered to the Rights Agent a supplemental agreement providing that the
provision in question of such Principal Party shall have been canceled, waived
or amended, or that the authorized securities shall be redeemed, so that the
applicable provision will have no effect in connection with, or as a consequence
of, the consummation of the proposed transaction.

     (e) The Company covenants and agrees that it shall not, at any time after
the Triggering Event, enter into any transaction of the type described in
clauses (i) through (iii) of Section 13(a) hereof if (i) at the time of or
immediately after such consolidation, merger, sale, transfer or other
transaction there are any rights, warrants or other instruments or securities
outstanding or agreements in effect which would substantially diminish or
otherwise eliminate the benefits intended to be afforded by the Rights, (ii)
prior to, simultaneously with or immediately after such consolidation, merger,
sale, transfer or other transaction, the stockholders of the Person who
constitutes, or would constitute, the Principal Party for purposes of Section
13(b) hereof shall have received a distribution of Rights previously owned by
such Person or any of its Affiliates or Associates or (iii) the form or nature
of organization of the Principal Party would preclude or limit the
exercisability of the Rights.


                                      -22-



     Section 14. Fractional Rights and Fractional Shares. (a) The Company 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 (as determined pursuant to the second sentence of
Section 11(d)(i) hereof) for the Trading Day immediately prior to the date on
which such fractional Rights would have been otherwise issuable; provided,
however, that if the Rights are not then publicly traded, the fair value of the
Rights on such date as determined in good faith by the Board of Directors of the
Company shall be used.

     (b) The Company shall not be required to issue fractions of Preferred
Shares (other than fractions which are integral multiples of one one-thousandth
of a Preferred Share) upon exercise of the Rights or to distribute certificates
which evidence fractional Preferred Shares (other than fractions which are
integral multiples of one one-thousandth of a Preferred Share). Fractions of
Preferred Shares in integral multiples of one one-thousandth of a Preferred
Share may, at the election of the Company, be evidenced by depositary receipts,
pursuant to an appropriate agreement between the Company and a depositary
selected by it; provided, that such agreement shall provide that the holders of
such depositary receipts shall have all the rights, privileges and preferences
to which they are entitled as beneficial owners of the Preferred Shares
represented by such depositary receipts. In lieu of fractional Preferred Shares
that are not integral multiples of one one-thousandth of a Preferred Share, the
Company shall pay to the registered holders of 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 Preferred Share. For the purposes of
this Section 14(b), the current market value of a Preferred Share shall be the
closing price of a Preferred Share (as determined pursuant to the second
sentence of Section 11(d)(i) 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 shares upon
exercise of a Right (except as provided above).

     Section 15. Rights of Action. (a) All rights of action in respect of this
Rights 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 to
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 Company to enforce, or otherwise act in respect of, his right to
exercise the Rights evidenced by such Right Certificate in 


                                      -23-



the manner provided in such Right Certificate and in this Rights Agreement.
Without limiting the foregoing or any remedies available to the holders of
Rights, it is specifically acknowledged that the holders of Rights would not
have an adequate remedy at law for any breach of this Rights 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 Rights Agreement.

          (b) Any holder of Rights who prevails in an action to enforce the
     provisions of this Rights Agreement shall be entitled to recover the
     reasonable costs and expenses, including attorneys' fees, incurred in such
     action.

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

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

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

          (c) the Company 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 Certificates or the associated Common
     Shares certificate made by anyone other than the Company or the Rights
     Agent) for all purposes whatsoever, and neither the Company nor the Rights
     Agent shall be affected by any notice to the contrary; and

          (d) notwithstanding anything in this Rights Agreement to the contrary,
     neither the Company nor the Rights Agent shall have any liability to any
     holder of a Right or other Person as a result of the inability of either
     the Company or the Rights Agent to perform any of their respective
     obligations under this Rights 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 that the
     Company must use its reasonable 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 


                                      -24-



be deemed for any purpose the holder of the Preferred Shares or any other
securities of the Company which may at any time be issuable on the exercise of
the Rights represented thereby, nor shall anything contained herein or in any
Right Certificate be construed to confer upon the holder of any Right
Certificate, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 25 hereof), or to receive dividends
or subscription rights, or otherwise, until the Right or Rights evidenced by
such Right Certificate shall have been exercised in accordance with the
provisions hereof.

     Section 18. Concerning the Rights Agent. (a) The Company agrees to pay to
the Rights Agent reasonable compensation for all services rendered by it
hereunder and, from time to time, on demand of the Rights Agent, its reasonable
expenses and counsel fees and other disbursements incurred in the administration
and execution of this Rights Agreement and the exercise and performance of its
duties hereunder. The Company also agrees to indemnify the Rights Agent for, and
to hold it harmless against, any loss, liability or expense, incurred without
negligence, bad faith or willful misconduct on the part of the Rights Agent, for
anything done or omitted by the Rights Agent in connection with the acceptance
and administration of this Rights Agreement, including the costs and expenses of
defending against any claim of liability in the premises.

     (b) The Rights Agent shall be protected and shall incur no liability for,
or in respect of any action taken, suffered or omitted by it in connection with,
its administration of this Rights Agreement in reliance upon any Right
Certificate or certificate for the Preferred Shares or Common Shares or for
other securities of the Company, instrument of assignment or transfer, power of
attorney, endorsement, affidavit, letter, notice, direction, consent,
certificate, statement or other paper or document believed by it to be genuine
and to be signed, executed and, where necessary, verified or acknowledged, by
the proper person or persons, or otherwise upon the advice of counsel as set
forth in Section 20 hereof.

     Section 19. Merger or Consolidation or Change of Name of Rights Agent. (a)
Any corporation into which the Rights Agent or any successor Rights Agent may be
merged or with which it may be consolidated, or any corporation resulting from
any merger or consolidation to which the Rights Agent or any successor Rights
Agent shall be a party, or any corporation succeeding to the stock transfer or
corporate trust powers of the Rights Agent or any successor Rights Agent, shall
be the successor to the Rights Agent under this Rights 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 Rights Agreement, any of the Right Certificates shall have been
countersigned but not delivered, any such successor Rights Agent may 


                                      -25-



adopt the countersignature of the 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 Rights
Agent 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 Rights Agreement.

     (b) In case at any time the name of the Rights Agent shall be changed and
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 Rights Agreement.

     Section 20. Duties of Rights Agent. The Rights Agent undertakes the duties
and obligations imposed by this Rights Agreement upon the following terms and
conditions, by all of which the Company 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 Company), and the opinion of such counsel shall be full and
     complete authorization and protection to the Rights Agent as to any action
     taken or omitted by it in good faith and in accordance with such opinion.

          (b) Whenever in the performance of its duties under this Rights
     Agreement the Rights Agent shall deem it necessary or desirable that any
     fact or matter be proved or established by the Company prior to taking or
     suffering any action hereunder, such fact or matter (unless other evidence
     in respect thereof be herein specifically prescribed) may be deemed to be
     conclusively proved and established by a certificate signed by any one of
     the Chairman of the Board, the Chief Executive Officer, the President, any
     Vice President, the Treasurer or the Secretary of the Company and delivered
     to the Rights Agent; and such certificate shall be full authorization to
     the Rights Agent for any action taken or suffered in good faith by it under
     the provisions of this Rights Agreement in reliance upon such certificate.

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

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


                                      -26-



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

          (f) The Company agrees that it will perform, execute, acknowledge and
     deliver or cause to be performed, executed, acknowledged and delivered all
     such further and other acts, instruments and assurances as may reasonably
     be required by the Rights Agent for the carrying out or performing by the
     Rights Agent of the provisions of this Rights 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 Secretary or the Treasurer of the
     Company, and to apply to such officers for advice or instructions in
     connection with its duties, and it shall not be liable for any action taken
     or suffered by it in good faith in accordance with instructions of any such
     officer or for any delay in acting while waiting for those instructions.

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

          (i) The Rights Agent may execute and exercise any of the rights or
     powers hereby vested in it or perform any duty hereunder either itself or
     by or through its attorneys or agents, and the Rights Agent shall not be
     answerable or accountable for any act, default, neglect or misconduct of
     any such attorneys 


                                      -27-



     or agents or for any loss to the Company resulting from any such act,
     default, neglect or misconduct, provided reasonable care was exercised in
     the selection and continued employment thereof.

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

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

     Section 21. Change of Rights Agent. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Rights
Agreement upon 30 days' notice in writing mailed to the Company and to each
transfer agent of the Common Shares or Preferred Shares by registered or
certified mail, and to the holders of the Right Certificates by first-class
mail. The Company may remove the Rights Agent or any successor Rights Agent upon
30 days' notice in writing, mailed to the Rights Agent or successor Rights
Agent, as the case may be, and to each transfer agent of the Common Shares or
Preferred Shares by registered or certified mail, and to the 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 Company shall appoint
a successor to the Rights Agent. If the Company shall fail to make such
appointment within a period of 30 days after giving notice of such removal or
after it has been notified in writing of such resignation or incapacity by the
resigning or incapacitated Rights Agent or by the holder of a Right Certificate
(who shall, with such notice, submit his Right Certificate for inspection by the
Company), 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 Company 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 million. After
appointment, the successor Rights Agent shall be vested with the same powers,
rights, duties and responsibilities as if it had been originally named as Rights
Agent without further act or deed; but the predecessor Rights Agent shall
deliver and transfer to the successor Rights Agent any property at the time held
by it hereunder, and execute and deliver any further 


                                      -28-



assurance, conveyance, act or deed necessary for the purpose. Not later than the
effective date of any such appointment the Company shall file notice thereof in
writing with the predecessor Rights Agent and each transfer agent of the Common
Shares or Preferred Shares, and 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 Rights
Agent or the appointment of the successor Rights Agent, as the case may be.

     Section 22. Issuance of Additional Rights and New Right Certificates.
Notwithstanding any of the provisions of this Rights Agreement or of the Rights
to the contrary, the Company may, at its option, issue new Right Certificates
evidencing Rights in such form as may be approved by its Board of Directors to
reflect any adjustment or change in the Purchase Price and the number or kind or
class of shares or other securities or property purchasable under the Right
Certificates made in accordance with the provisions of this Rights 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 Company (a) shall, with respect to Common Shares so issued
or sold pursuant to the exercise of stock options or under any employee plan or
arrangement, or upon the exercise, conversion or exchange of securities, notes
or debentures issued by the Company, and (b) may, in an other case, if deemed
necessary or appropriate by the Board of Directors of the Company, issue Right
Certificates representing the appropriate number of Rights in connection with
such issuance or sale; provided, however, that (i) no such Right Certificate
shall be issued if, and to the extent that, the Company shall be advised by
counsel that such issuance would create a significant risk of material adverse
tax consequences to the Company or the Person to whom such Right Certificate
would be issued, and (ii) no such 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. (a) The Board of Directors of the Company may, at
its option, at any time prior to the Close of Business on the earlier of (i) the
tenth day following the Shares Acquisition Date or (ii) the Final Expiration
Date, redeem all but not less than all the then outstanding Rights at a
redemption price of $.01 per Right, appropriately adjusted to reflect any stock
split, stock dividend or similar transaction occurring after the date hereof
(such redemption price being hereinafter referred to as the "Redemption Price").
Notwithstanding anything contained in this Rights Agreement to the contrary, the
Rights shall not be exercisable upon the occurrence of a Triggering Event until
such time as the Company's right of redemption hereunder has expired. 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. The Company may, at its option, pay the
Redemption Price in cash, Common Shares (based on the current market price at
the time of redemption) or any other form of consideration deemed appropriate by
the Board of Directors.


                                      -29-



     (b) Notwithstanding the provision of Section 23(a), in the event that a
majority of the Board of Directors of the Company is elected by stockholder
action at an annual or special meeting of stockholders, then until the 180th day
following the effectiveness of such election (including any postponement or
adjournment thereof), the Rights shall not be redeemed if such redemption is
reasonably likely to have the purpose or effect of facilitating a Transaction
with an Interested Person.

     (c) 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. The Company shall promptly give public
notice of any such redemption; provided, however, that the failure to give, or
any defect in, any such notice shall not affect the validity of such redemption.
Within 10 days after such action of the Board of Directors ordering the
redemption of the Rights, the Company shall mail a notice of redemption to all
the holders of the then outstanding Rights at their last addresses as they
appear upon the registry books of the Rights Agent or, prior to the Distribution
Date, on the registry books of the transfer agent for the Common Shares. Any
notice which is mailed in the manner herein provided shall be deemed given,
whether or not the holder receives the notice. Each such notice of redemption
will state the method by which the payment of the Redemption Price will be made.
Neither the Company nor any of its Affiliates or Associates may redeem, acquire
or purchase for value any Rights at any time in any manner other than that
specifically set forth in this Section 23 or in Section 24 hereof, and other
than in connection with the purchase of Common Shares prior to the Distribution
Date.

     Section 24. Exchange. (a) The Board of Directors of the Company may, at its
option, at any time after the Triggering Event, exchange all or part of the then
outstanding and exercisable Rights (which shall not include Rights that have
become void pursuant to the provisions of Section 11(a)(ii) hereof) for Common
Shares at an exchange ratio of one Common Share per Right, appropriately
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date hereof (such amount per Right being hereinafter
referred to as the "Exchange Ratio"). Notwithstanding the foregoing, the Board
of Directors shall not be empowered to effect such exchange at any time after
any Person (other than the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or any such Subsidiary, or any entity holding Common
Shares for or pursuant to the terms of any such plan), together with all
Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or
more of the Common Shares then outstanding. From and after the occurrence of an
event specified in Section 13(a) hereof, any Rights that theretofore have not
been exchanged pursuant to this Section 24(a) shall thereafter be exercisable
only in accordance with Section 13 and may not be exchanged pursuant to this
Section 24(a). The exchange 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.


                                      -30-



     (b) Notwithstanding the provision of Section 24(a), in the event that a
majority of the Board of Directors of the Company is elected by stockholder
action at an annual or special meeting of stockholders, then until the 180th day
following the effectiveness of such election (including any postponement or
adjournment thereof), the Rights shall not be exchanged pursuant to Section
24(a) if such exchange is reasonably likely to have the purpose or effect of
facilitating a Transaction with an Interested Person.

     (c) Immediately upon the action of the Board of Directors of the Company
ordering the exchange of any Rights pursuant to paragraph (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 Company
shall promptly give public notice of any such exchange; provided, however, that
the failure to give, or any defect in, such notice shall not affect the validity
of such exchange. The Company promptly shall mail a notice of any such exchange
to all of the holders of such Rights at their last addresses as they appear upon
the registry books of the Rights Agent. Any notice which is mailed in the manner
herein provided shall be deemed given, whether or not the holder receives the
notice. Each such notice of exchange will state the method by which the exchange
of the Common Shares for Rights will be effected and, in the event of any
partial exchange, the number of Rights which will be exchanged. Any partial
exchange shall be effected pro rata based on the number of Rights (other than
Rights which have become void pursuant to the provisions of Section 11(a)(ii)
hereof) held by each holder of Rights.

     (d) In the event that there shall not be sufficient Common Shares issued
but not outstanding or authorized but unissued to permit any exchange of Rights
as contemplated in accordance with Section 24(a), the Company shall either take
such action as may be necessary to authorize additional Common Shares for
issuance upon exchange of the Rights or alternatively, at the option of a
majority of the Board of Directors, with respect to each Right (i) pay cash in
an amount equal to the Current Value (as hereinafter defined), in lieu of
issuing Common Shares in exchange therefor, or (ii) issue debt or equity
securities or a combination thereof, having a value equal to the Current Value,
in lieu of issuing Common Shares in exchange for each such Right, where the
value of such securities shall be determined by a nationally recognized
investment banking firm selected by majority vote of the Board of Directors, or
(iii) deliver any combination of cash, property, Common Shares and/or other
securities having a value equal to the Current Value in exchange for each Right.
For purposes of this Section 24(d) only, the Current Value shall mean the
product of the current per share market price of Common Shares (determined
pursuant to Section 11(d) on the date of the occurrence of the event described
above in subparagraph (a)) multiplied by the number of Common Shares for which
the Right otherwise would be exchangeable if there were sufficient shares
available. To the extent that the Company determines that some action need be
taken pursuant to clauses (i), (ii) or (iii) of this Section 24(d), the Board of
Directors may temporarily suspend the exercisability of the Rights for a 


                                      -31-



period of up to sixty (60) days following the date on which the event described
in Section 24(a) shall have occurred, in order to seek any authorization of
additional Common Shares and/or to decide the appropriate form of distribution
to be made pursuant to the above provision and to determine the value thereof.
In the event of any such suspension, the Company shall issue a public
announcement stating that the exercisability of the Rights has been temporarily
suspended.

     (e) The Company shall not be required to issue fractions of Common Shares
or to distribute certificates which evidence fractional Common Shares. In lieu
of such fractional Common Shares, the Company shall pay to the registered
holders of the Right Certificates with regard to which such fractional Common
Shares would otherwise be issuable an amount in cash equal to the same fraction
of the current market value of a whole Common Share. For the purposes of this
paragraph (e), the current market value of a whole Common Share shall be the
closing price of a Common Share (as determined pursuant to the second sentence
of Section 11(d)(i) hereof) for the Trading Day immediately prior to the date of
exchange pursuant to this Section 24.

     Section 25. Notice of Certain Events. (a) In case the Company shall propose
(i) to pay any dividend payable in stock of any class to the holders of its
Preferred Shares or to make any other distribution to the holders of its
Preferred Shares (other than a regular quarterly cash dividend), (ii) to offer
to the holders of its Preferred Shares rights or warrants to subscribe for or to
purchase any additional Preferred Shares or shares of stock of any class or any
other securities, rights or options, (iii) to effect any reclassification of its
Preferred Shares (other than a reclassification involving only the subdivision
or combination of outstanding Preferred Shares), (iv) to effect any
consolidation or merger into or with, or to effect any sale or other transfer
(or to permit one or more of its Subsidiaries to effect any sale or other
transfer), in one or more transactions, of 50% or more of the assets or earning
power of the Company and its Subsidiaries (taken as a whole) to, any other
Person, (v) to effect the liquidation, dissolution or winding up of the Company,
or (vi) to declare or pay any dividend on the Common Shares payable in Common
Shares or to effect a subdivision, combination or consolidation of the Common
Shares (by reclassification or otherwise than by payment of dividends in Common
Shares), then, in each such case, the Company shall give to each holder of a
Right Certificate, in accordance with Section 26 hereof, a notice of such
proposed action, which shall specify the record date for the purposes of such
stock dividend, or distribution of rights or warrants, or the date on which such
reclassification, consolidation, merger, sale, transfer, liquidation,
dissolution, or winding up is to take place and the date of participation
therein by the holders of the Common Shares and/or Preferred Shares, if any such
date is to be fixed, and such notice shall be so given in the case of any action
covered by clause (i) or (ii) above at least 10 days prior to the record date
for determining holders of the Preferred Shares for purposes of such action, and
in the case of any such other action, at least 10 days prior to the date of the
taking of such proposed action or the date of participation therein by the
holders of the Common Shares and/or Preferred Shares, whichever shall be the
earlier.


                                      -32-



     (b) In case the event set forth in Section 11(a)(ii) or Section 13 hereof
shall occur, then the Company 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)
and Section 13 hereof.

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

addressed to such holder at the address of such holder as shown on the registry
books of the Company.

     Section 27. Supplements and Amendments. (a) Except as provided in the last
sentence of this Section 27, for so long as the Rights are then redeemable, the
Company may in its sole and absolute discretion, and the Rights Agent shall if
the Company so directs, supplement or amend any provision of this Rights
Agreement (including, without limitation, the date on which the Distribution
Date shall occur, the time during which the Rights may be redeemed pursuant to
Section 23 or any provision of the Certificate of Designation) without the
approval of any holder of the Rights. At any time when the Rights are no longer
redeemable, except as provided in the last sentence of this Section 27, the
Company may, and the Rights Agent shall if the Company so directs, amend this
Rights Agreement without the approval of any holders of Right Certificates (i)
to cure any ambiguity or to correct or supplement any provision contained herein
which may be defective or inconsistent with any other provision of this Rights
Agreement or (ii) to make any other provisions in regard to matters or 


                                      -33-



questions arising hereunder which the Company may deem necessary or desirable;
provided that no such supplement or amendment shall adversely affect the
interests of the holders of Right Certificates (other than an Acquiring Person
or an Affiliate or Associate of an Acquiring Person), and no such amendment may
cause the Rights again to become redeemable or cause this Rights Agreement again
to become amendable other than in accordance with this sentence. Upon the
delivery of a certificate from an appropriate officer of the Company which
states that the proposed supplement or amendment is in compliance with the terms
of this Section 27, the Rights Agent shall execute such supplement or amendment.
Notwithstanding any other provisions hereof, the Rights Agent's consent must be
obtained regarding any amendment or supplement pursuant to this Section 27 which
alters the Rights Agent's rights or duties, which consent will not be
unreasonably withheld.

     (b) Notwithstanding the provisions of Section 27(a), in the event that a
majority of the Board of Directors of the Company is elected by stockholder
action at an annual or special meeting of stockholders, then until the 180th day
following the effectiveness of such election (including any postponement or
adjournment thereof), this Agreement shall not be supplemented or amended in any
manner reasonably likely to have the purpose or effect of facilitating a
Transaction with an Interested Person.

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

     Section 29. Benefits of this Rights Agreement. Nothing in this Rights
Agreement shall be construed to give to any person or corporation other than the
Company, 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 Rights Agreement; but this Rights Agreement
shall be for the sole and exclusive benefit of the Company, the Rights Agent and
the registered holders of the Right Certificates (and, prior to the Distribution
Date, the Common Shares).

     Section 30. Determinations and Actions by the Board of Directors. Except as
explicitly otherwise provided in this Rights Agreement, the Board of Directors
of the Company shall have the exclusive power and authority to administer this

or advisable in the administration of this Rights Agreement, including, without
limitation, the right and power to (i) interpret the provisions of this Rights
Agreement and (ii) make all determinations deemed necessary or advisable for the
administration of this Rights Agreement (including, without limitation, a
determination to redeem or not redeem the Rights or to amend this Rights
Agreement and a determination of whether there is an Acquiring Person). All such
actions, calculations, interpretations and determinations (including, for
purposes of clause (y) below, all omissions with respect to the foregoing) that
are done or made by the Board of Directors of the Company in 


                                      -34-



good faith shall (x) be final, conclusive and binding on the Company, the Rights
Agent, the holders of the Rights, as such, and all other parties and (y) not

                          BIO-TECHNOLOGY GENERAL CORP.

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

                                  ------------


     Bio-Technology General Corp., a corporation organized and existing under
the General Corporation Law of the State of Delaware (hereinafter called the
"Corporation"), DOES HEREBY CERTIFY:

     That pursuant to the authority vested in the Board of Directors in
accordance with the provisions of the Certificate of Incorporation of the said
Corporation, the said Board of Directors on October 7, 1998 adopted the
following resolution creating a series of 150,000 shares of Preferred Stock
designated as "Series A Junior Participating Preferred Stock":

          RESOLVED, that pursuant to the authority vested in the Board of
     Directors of this Corporation in accordance with the provisions of the
     Certificate of Incorporation, a series of Preferred Stock, par value $.01
     per share, of the Corporation be and hereby is created, and that the
     designation and number of shares thereof and the voting and other powers,
     preferences and relative, participating, optional or other rights of the
     shares of such series and the qualifications, limitations and restrictions
     thereof are as follows:

          Series A Junior Participating Cumulative Preferred Stock:

          Section 1. Designation and Amount. The shares of such series shall be
designated as "Series A Junior Participating Cumulative Preferred Stock" (the
"Series A Preferred Stock"), and the number of shares initially constituting the
Series A Preferred Stock shall be 150,000. Such number of shares may be
increased or decreased by 


                                      -A1-



resolution of the Board of Directors; provided, however, that no decrease shall
reduce the number of shares of Series A Preferred Stock to a number less than
the number of shares then outstanding plus the number of shares reserved for
issuance upon the exercise of outstanding options, rights or warrants or upon
the conversion of any outstanding securities issued by the Corporation
convertible into Series A Preferred Stock.

          Section 2. Dividends and Distributions.

          (A) Subject to the rights of the holders of any shares of any series
     of Preferred Stock (or any similar stock) ranking prior and superior to the
     Series A Preferred Stock with respect to dividends, the holders of shares
     of Series A Preferred Stock, in preference to the holders of Common Stock,
     par value $.01 per share (the "Common Stock"), of the Corporation, and of
     any other junior stock, shall be entitled to receive, when, as and if
     declared by the Board of Directors out of funds legally available for the
     purpose, quarterly dividends payable in cash on the first day of March,
     June, September and December in each year (each such date being referred to
     herein as a "Quarterly Dividend Payment Date"), commencing on the first
     Quarterly Dividend Payment Date after the first issuance of a share or
     fraction of a share of Series A Preferred Stock, in an amount per share
     (rounded to the nearest cent) equal to the greater of (a) $10 or (b)
     subject to the provision for adjustment hereinafter set forth, 1,000 times
     the aggregate per share amount of all cash dividends, and 1,000 times the
     aggregate per share amount (payable in kind) of all non-cash dividends or
     other distributions, other than a dividend payable in shares of Common
     Stock or a subdivision of the outstanding shares of Common Stock (by
     reclassification or otherwise), declared on the Common Stock since the
     immediately preceding Quarterly Dividend Payment Date or, with respect to
     the first Quarterly Dividend Payment Date, since the first issuance of any
     share or fraction of a share of Series A Preferred Stock. In the event the
     Corporation shall at any time declare or pay any dividend on the Common
     Stock payable in shares of Common Stock, or effect a subdivision or
     combination or consolidation of the outstanding shares (by reclassification
     or otherwise than by payment of a dividend in shares of Common Stock) into
     a greater or lesser number of shares of Common Stock, then in each such
     case the amount to which holders of shares of Series A Preferred Stock were
     entitled immediately prior to such event under clause (b) of the preceding
     sentence shall be adjusted by multiplying such amount by a fraction, the
     numerator of which is the number of shares of Common Stock outstanding
     immediately after such event and the denominator of which is the number of
     shares of Common Stock that were outstanding immediately prior to such
     event.

          (B) The Corporation shall declare a dividend or distribution on the
     Series A Preferred Stock as provided in paragraph (A) of this Section
     immediately after it declares a dividend or distribution on the Common
     Stock (other than a dividend payable in shares of Common Stock); provided
     that, in 


                                      -A2-



     the event no dividend or distribution shall have been declared on the
     Common Stock during the period between any Quarterly Dividend Payment Date
     and the next subsequent Quarterly Dividend Payment Date, a dividend of $10
     per share on the Series A Preferred Stock shall nevertheless be payable on
     such subsequent Quarterly Dividend Payment Date.

          (C) Dividends shall begin to accrue and be cumulative on outstanding
     shares of Series A Preferred Stock from the Quarterly Dividend Payment Date
     next preceding the date of issue of such shares, unless the date of issue
     of such shares is prior to the record date for the first Quarterly Dividend
     Payment Date, in which case dividends on such shares shall begin to accrue
     from the date of issue of such shares, or unless the date of issue is a
     Quarterly Dividend Payment Date or is a date after the record date for the
     determination of holders of shares of Series A Preferred Stock entitled to
     receive a quarterly dividend and before such Quarterly Dividend Payment
     Date, in either of which events such dividends shall begin to accrue and be
     cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid
     dividends shall not bear interest. Dividends paid on the shares of Series A
     Preferred Stock in an amount less than the total amount of such dividends
     at the time accrued and payable on such shares shall be allocated pro rata
     on a share-by-share basis among all such shares at the time outstanding.
     The Board of Directors may fix a record date for the determination of
     holders of shares of Series A Preferred Stock entitled to receive payment
     of a dividend or distribution declared thereon, which record date shall be
     not more than 60 days prior to the date fixed for the payment thereof, and
     shall be the same as the record date for any corresponding dividend or
     distribution on the Common Stock.

          (D) So long as any shares of the Series A Preferred Stock are
     outstanding, no dividends or other distributions shall be declared, paid or
     distributed, or set aside for payment or distribution, on the Common Stock
     unless, in each case, the dividend required by this Section 2 to be
     declared on the Series A Preferred Stock shall have been declared.

          (E) The holders of the shares of Series A Preferred Stock shall not be
     entitled to receive any dividends or other distributions except as provided
     herein.

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

          (A) Subject to the provision for adjustment hereinafter set forth,
     each share of Series A Preferred Stock shall entitle the holder thereof to
     1,000 votes on all matters submitted to a vote of the stockholders of the
     Corporation. In the event the Corporation shall at any time declare or pay
     any dividend on the Common Stock payable in shares of Common Stock, or
     effect a subdivision or combination or consolidation of the outstanding
     shares of Common Stock (by reclassification or otherwise than by payment of
     a dividend in shares of Common 


                                      -A3-



     Stock into a greater or lesser number of shares of Common Stock), then in
     each such case the number of votes per share to which holders of shares of
     Series A Preferred Stock were entitled immediately prior to such event
     shall be adjusted by multiplying such number by a fraction, the numerator
     of which is the number of shares of Common Stock outstanding immediately
     after such event and the denominator of which is the number of shares of
     Common Stock that were outstanding immediately prior to such event.

          (B) Except as otherwise provided herein, in any other Certificate of
     Designations creating a series of Preferred Stock or any similar stock, or
     by law, the holders of shares of Series A Preferred Stock and the holders
     of shares of Common Stock and any other capital stock of the Corporation
     having general voting rights shall vote together as one class on all
     matters submitted to a vote of stockholders of the Corporation.

          (C) Except as set forth herein, or as otherwise provided by law,
     holders of Series A Preferred Stock shall have no special voting rights and
     their consent shall not be required (except to the extent they are entitled
     to vote with holders of Common Stock as set forth herein) for taking any
     corporate action.

          Section 4. Certain Restrictions.

          (A) Whenever quarterly dividends or other dividends or distributions
     payable on the Series A Preferred Stock as provided in Section 2 are in
     arrears, thereafter and until all accrued and unpaid dividends and
     distributions, whether or not declared, on shares of Series A Preferred
     Stock outstanding shall have been paid in full, the Corporation shall not:

               (i) declare or pay dividends, or make any other distributions, on
          any shares of stock ranking junior (either as to dividends or upon
          liquidation, dissolution or winding up) to the Series A Preferred
          Stock;

               (ii) declare or pay dividends, or make any other distributions,
          on any shares of stock ranking on a parity (either as to dividends or
          upon liquidation, dissolution or winding up) with the Series A
          Preferred Stock, except dividends paid ratably on the Series A
          Preferred Stock and all such parity stock on which dividends are
          payable or in arrears in proportion to the total amounts to which the
          holders of all such shares are then entitled;

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


                                      -A4-



          upon dissolution, liquidation or winding up) to the Series A Preferred
          Stock; or

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

          (B) The Corporation shall not permit any subsidiary of the Corporation
     to purchase or otherwise acquire for consideration any shares of stock of
     the Corporation unless the Corporation could, under paragraph (A) of this
     Section 4, purchase or otherwise acquire such shares at such time and in
     such manner.

     Section 5. Reacquired Shares. Any shares of Series A Preferred Stock
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and canceled promptly after the acquisition thereof. All such
shares shall upon their cancellation become authorized but unissued shares of
Preferred Stock and may be reissued as part of a new series of Preferred Stock
subject to the conditions and restrictions on issuance set forth herein, in the
Certificate of Incorporation, or in any other Certificate of Designations
creating a series of Preferred Stock or any similar stock or as otherwise
required by law.

     Section 6. Liquidation, Dissolution or Winding Up. Upon any liquidation,
dissolution or winding up of the Corporation, voluntary or otherwise, no
distribution shall be made (1) to the holders of shares of stock ranking junior
(either as to dividends or upon liquidation, dissolution or winding up) to the
Series A Preferred Stock unless, prior thereto, the holders of shares of Series
A Preferred Stock shall have received the greater of (a) $1,000 per share, plus
an amount equal to accrued and unpaid dividends and distributions thereon,
whether or not declared, to the date of such payment, or (b) an aggregate amount
per share, subject to the provision for adjustment hereinafter set forth, equal
to 1,000 times the aggregate amount to be distributed per share to holders of
shares of Common Stock, or (2) to the holders of shares of stock ranking on a
parity (either as to dividends or upon liquidation, dissolution or winding up)
with the Series A Preferred Stock, except distributions made ratably on the
Series A Preferred Stock and all such parity stock in proportion to the total
amounts to which the holders of all such shares are entitled upon such
liquidation, dissolution or winding up. In the event the Corporation shall at
any time declare or pay any dividend on the Common Stock payable in shares of
Common Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) 


                                      -A5-



into a greater or lesser number of shares of Common Stock, then in each such
case the aggregate amount to which holders of shares of Series A Preferred Stock
were entitled immediately prior to such event under clause (1)(b) of the
preceding sentence shall be adjusted by multiplying such amount by a fraction
the numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

     Section 7. Consolidation, Merger, etc. In case the Corporation shall enter
into any consolidation, merger, combination or other transaction in which the
shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case each share of
Series A Preferred Stock shall at the same time be similarly exchanged or
changed into an amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 1,000 times the aggregate amount of stock,
securities, cash and/or any property (payable in kind), as the case may be, into
which or for which each share of Common Stock is changed or exchanged. In the
event the Corporation shall at any time declare or pay any dividend on the
Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount set forth in the preceding sentence with respect to the
exchange or change of shares of Series A Preferred Stock shall be adjusted by
multiplying such amount by a fraction, the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

     Section 8. No Redemption. The shares of Series A Preferred Stock shall not
be redeemable.

     Section 9. Rank. The Series A Preferred Stock shall rank, with respect to
the payment of dividends and the distribution of assets, junior to all series of
any other class of the Corporation's Preferred Stock, unless the Board of
Directors shall specifically determine otherwise in fixing the powers,
preferences and relative, participating, optional and other special rights of
the shares of such series and the qualifications, limitations and restrictions
thereof.

     Section 10. Fractional Shares. The Series A Preferred Stock shall be
issuable upon exercise of the Rights issued pursuant to the Rights Agreement in
whole shares or in any fraction of a share that is one one-thousandths
(1/1000ths) of a share or any integral multiple of such fraction which shall
entitle the holder, in proportion to such holder's fractional shares, to receive
dividends, exercise voting rights, participate in distributions and to have the
benefit of all other rights of holders of Series A Preferred Stock. In lieu of
fractional shares, the Corporation, prior to the first issuance of a share or a
fraction of a share of Series A Preferred Stock, may elect (1) to make a cash
payment as provided in the Rights Agreement for fractions of a share 


                                      -A6-



other than one one-thousandths (1/1000ths) of a share or any integral multiple
thereof or (2) to issue depository receipts evidencing such authorized fraction
of a share of Series A Preferred Stock pursuant to an appropriate agreement
between the Corporation and a depository selected by the Corporation; provided
that such agreement shall provide that the holders of such depository receipts
shall have all the rights, privileges and preferences to which they are entitled
as holders of the Series A Preferred Stock.

     Section 11. Amendment. The Certificate of Incorporation of the Corporation
shall not be amended in any manner which would materially alter or change the
powers, preferences or special rights of the Series A Preferred Stock so as to
affect them adversely without the affirmative vote of the holders of at least
two-thirds of the outstanding shares of Series A Preferred Stock, voting
together as a single class.

     IN WITNESS WHEREOF, this Certificate of Designations is executed on behalf
of the Corporation by its President and attested by its Secretary this _____ day
of October, 1998.

                                    Exhibit C

                          SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES

     On October 7, 1998, the Board of Directors of Bio-Technology General Corp.
(the "Company") adopted a Shareholder Rights Plan (the "Rights Plan"). The
purpose of the Rights Plan is to deter certain coercive takeover tactics and
enable the Board of Directors to represent effectively the interests of
stockholders in the event of a takeover attempt. The Rights Plan does not deter
negotiated mergers or business combinations that the Board of Directors
determines to be in the best interests of the Company and its stockholders.

     To implement the Rights Plan the Board of Directors declared a dividend of
one preferred share purchase right (a "Right") for each outstanding share of
common stock, par value $.01 per share (the "Common Shares"), of the Company.
The dividend is payable on October 22, 1998 (the "Record Date") to the
stockholders of record at the close of business on that date. Each Right
entitles the registered holder to purchase from the Company one one-thousandth
of a share of Series A Junior Participating Cumulative Preferred Stock, par
value $.01 per share (the "Preferred Shares"), of the Company at a price of
$45.00 per one one-thousandth of a Preferred Share (the "Purchase Price"),
subject to adjustment. The description and terms of the Rights are set forth in
a Rights Agreement (the "Rights Agreement") between the Company and American
Stock Transfer & Trust Company, as Rights Agent (the "Rights Agent").

RIGHTS ATTACH TO COMMON SHARES INITIALLY

     Initially and until a Distribution Date (as defined below) occurs, the
Rights are attached to all Common Shares and no separate Rights certificates
will be issued. During this initial period,

     o    the Rights are not exercisable;

     o    the Rights are transferred with the Common Shares and are not
          transferable separately from the Common Shares;

     o    new Common Share certificates issued will contain a notation
          incorporating the Rights Agreement by reference; and

     o    the transfer of any Common Shares will also constitute the transfer of
          the Rights associated with those Common Shares.

DISTRIBUTION OF RIGHTS

     Separate certificates evidencing the Rights will be mailed to holders of
record of the Common Shares on the "Distribution Date." The Distribution Date is
the earlier to occur of the following two events:


                                      C-1



     o    the tenth day after a public announcement that a person or group of
          affiliated or associated persons has acquired 20% or more of the
          outstanding Common Shares (thereby becoming an "Acquiring Person"
          under the Rights Plan); or

     o    the tenth business day (or such later date as may be determined by
          action of the Board of Directors prior to such time as any person or
          group of affiliated or associated persons becomes an Acquiring Person)
          after the commencement or announcement of a tender or exchange offer
          by a person or group for 20% or more of the outstanding Common Shares.

     Acquisitions by the Company, any subsidiary or employee benefit plan of the
Company or any other person approved in advance by the Board of Directors will
not result in such person becoming an Acquiring Person.

     After the Distribution Date, the Rights will be tradable separately from
the Common Shares. After the Distribution Date and after the Company's right to
redeem (as described below) has expired, the Rights will be exercisable in two
different ways depending on the circumstances as set forth below.

RIGHT TO PURCHASE COMPANY STOCK

     If a person or group acquires 20% or more of the outstanding Common Shares
(thereby becoming an Acquiring Person) and the Company's redemption right has
expired, each holder of a Right (except those held by the Acquiring Person and
its affiliates and associates) will have the right to purchase, upon exercise,
Common Shares (or, in certain circumstances, Preferred Shares or other similar
securities of the Company) having a value equal to two times the exercise price
of the Right. In other words, the Rights holders other than the Acquiring Person
may purchase Common Shares at a 50% discount.

     For example, at the exercise price of $45 per Right, each Right not owned
by an Acquiring Person would entitle its holder to purchase $90 worth of Common
Shares (or other consideration, as noted above) for $45. Assuming a value of $9
per Common Share at such time, the holder of each valid Right would be entitled
to purchase ten Common Shares for $45.

RIGHT TO PURCHASE ACQUIRING PERSON STOCK

     Alternatively, if, in a transaction not approved by the Board of Directors,
the Company is acquired in a merger or other business combination or 50% or more
of its assets or earning power are sold after a person or group has become an
Acquiring Person, and the Company's redemption right has expired, proper
provision will be made so that each holder of a Right will thereafter have the
right to purchase, upon exercise, that number of shares of common stock of the
acquiring company as have a market value of two times the exercise price of the
Right. In other words, a Rights holder may purchase the acquiring company's
common stock at a 50% discount.


                                      C-2



EXCHANGE OF COMPANY STOCK FOR RIGHTS

     At any time after any person or group becomes an Acquiring Person and
before the Acquiring Person acquires 50% or more of the outstanding Common
Shares, the Board of Directors may exchange the Rights (other than Rights owned
by the Acquiring Person which will have become void), in whole or in part, at an
exchange ratio of one Common Share, or one one-thousandth of a Preferred Share
(or of a share of a class or series of the Company's preferred stock having
equivalent rights, preferences and privileges), per Right (subject to
adjustment).

REDEMPTION

     The Rights are redeemable by the Company in whole but not in part at a
price of $.01 per Right at any time up to and including the tenth day after the
time that a person or a group has become an Acquiring Person, subject to
extension of this redemption period by the Board of Directors. Immediately upon
redemption the right to exercise will terminate and the only right of holders
will be to receive the redemption price.

EXPIRATION OF RIGHTS

     The Rights will expire on October 6, 2008 unless the expiration date is
extended by amendment as described below or unless the Rights are earlier
redeemed or exchanged by the Company as described above.

AMENDMENTS

     As long as the Rights are redeemable, the terms of the Rights may be
amended by the Board of Directors in its discretion without the consent of the
Rights holders. After that time, no amendment may adversely affect the interests
of the Rights holders (other than the Acquiring Person).

MISCELLANEOUS

     The number of outstanding Rights and the number of one one-thousandths of a
Preferred Share issuable upon exercise of each Right are subject to adjustment
under certain circumstances.

     Because of the nature of the Preferred Shares' dividend, liquidation and
voting rights, the value of the one one-thousandth interest in a Preferred Share
that may be purchased upon exercise of each Right should approximate the value
of one Common Share.

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