                      AMENDED AND RESTATED RIGHTS AGREEMENT
                                        
          Agreement, dated as of October 31, 1998, by and between MEDIMMUNE,
INC., a Delaware corporation (the "Company"), and AMERICAN STOCK TRANSFER &
TRUST COMPANY (the "Rights Agent").

                              W I T N E S S E T H :
                                        
          WHEREAS, on July 9, 1997, the Board of Directors of the Company
approved and adopted a Rights Agreement, dated as of such date, by and between
the Company and the Rights Agent (the "Original Rights Agreement") and, as
contemplated by the Original Rights Agreement, such Board of Directors
authorized the issuance, and declared a dividend, of one right (a "Right") for
each share of Common Stock, $.01 par value per share, of the Company outstanding
as of the close of business on July 21, 1997 (the "Record Date"), each such
Right representing the right to purchase one one-hundredth of a share of Series
B Junior Preferred Stock of the Company ("Preferred Stock") having the rights
and preferences set forth in the form of Certificate of Designations attached
hereto as Exhibit A;

          WHEREAS, the Board of Directors of the Company further authorized the
issuance of one Right (subject to adjustment) with respect to each share of
Common Stock which may be issued between the Record Date and the earlier to
occur of the Redemption Date or the Final Expiration Date (as such terms are
hereinafter defined); and

          WHEREAS, as of October 31, 1998, the Board of Directors of the Company
determined to amend and restate the Original Rights Agreement in order to
eliminate the provisions thereof relating to Continuing Directors.

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

          Section 1.     Certain Definitions.

          For purposes of this Agreement, the following terms shall 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 shares of any class of Voting Stock (as such term
          is hereinafter defined) of the Company then outstanding; provided
          that, an Acquiring Person shall not include (i) an Exempt Person (as
          such term is hereinafter defined) or (ii) any Person, together with
          all Affiliates and Associates of such Person, who or which would be an
          Acquiring Person solely by reason of (x) being the Beneficial Owner of
          shares of Voting Stock of the Company, the Beneficial Ownership of
          which was acquired by such Person pursuant to any action or
          transaction or series of related actions or transactions approved by
          the Board of Directors before such Person otherwise became an
          Acquiring Person or (y) a reduction in the number of issued and
          
                                        1
<PAGE>
          outstanding shares of Voting Stock of the Company pursuant to a
          transaction or a series of related transactions approved by the Board
          of Directors of the Company. 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 shares of Common Stock 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 an "Acquiring Person" for any purposes of this Rights
          Agreement.
          
               (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 Securities Exchange Act of 1934, as amended
          ("Exchange Act"), as in effect on the date of this Rights Agreement.
          
               (c)       A person shall be deemed the "Beneficial Owner" of, or
          to "Beneficially Own", any securities (and correlative terms shall
          have correlative meanings);
          
                    (i)       which such Person or any of such Person's
               Affiliates or Associates, directly or indirectly, "beneficially
               owns" (as determined pursuant to Rule 13d-3 of the General Rules
               and Regulations under the Exchange Act); or
               
               (ii)      which such Person or any of such Person's Affiliates or
               Associates, directly or indirectly, has (A) the right to acquire
               (whether such right is exercisable immediately or only after the
               passage of time or the fulfillment of a condition or both)
               pursuant to any agreement, arrangement or understanding, or upon
               the exercise of conversion rights, exchange rights, other 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", securities
               tendered pursuant to a tender or exchange offer made by such
               Person or any of such Person's Affiliates or Associates until
               such tendered securities are accepted for purchase or exchange or
               (B) the right to vote, alone or in concert with others, pursuant
               to any agreement, arrangement or understanding (whether or not in
               writing); provided, however, that a Person shall not be deemed
               the "Beneficial Owner" of, or to "Beneficially Own", any
               securities if the agreement, arrangement or understanding to vote
               such security (1) arises solely from a revocable proxy or consent
               given in response to a proxy or consent solicitation made
               pursuant to, and in accordance with, the applicable rules and
               regulations under the Exchange Act and (2) is not at the time
               reportable by such Person on a Schedule 13D report under the
               Exchange Act (or any comparable or successor report); or
                                        2
<PAGE>
                    (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 (whether or not in writing) for the
               purpose of acquiring, holding, voting (except as described in
               clause (B) of subparagraph (ii) of this paragraph (c)) or
               disposing of any securities of the Company.
               
                    Notwithstanding anything in this paragraph (c) to the
               contrary, if a Person, who together with any other stockholders
               of the Company holds, in the aggregate, greater than 50% of the
               Voting Stock of the Company, approves any action of the
               stockholders by written consent in lieu of a stockholders
               meeting, such Person shall be deemed to be the "Beneficial Owner"
               of all of the Voting Stock that is voted pursuant to such written
               consent.  Further, notwithstanding anything in this paragraph (c)
               to the contrary, a Person engaged in the business of underwriting
               securities shall not be deemed the "Beneficial Owner" of, or to
               "Beneficially Own," any securities acquired in good faith in a
               firm commitment underwriting until the expiration of forty days
               after the date of such acquisition.
               
                    Notwithstanding anything in this paragraph (c) to the
               contrary, the phrase "then outstanding," when used with reference
               to a Person's Beneficial Ownership of securities of the Company,

          The Company hereby appoints the Rights Agent to act as agent for the
Company in accordance with the terms and conditions hereof, and the Rights Agent
hereby accepts such appointment.  The Company may from time to time appoint such
Co-Rights Agents as it may deem necessary or desirable.

          Section 3.     Issuance of Rights Certificates.

          (a)       On the Record Date (or as soon as practicable thereafter),
the Company or the Rights Agent shall send a copy of a Summary of Rights, in
substantially the form attached hereto as Exhibit B (the "Summary of Rights"),
by first class mail, postage prepaid, to each record holder of the Common Stock
as of the close of business on the Record Date, at the address of such holder
shown on the records of the Company.

          (b)       Until the Close of Business on the day (or such later date
as may be determined by action of the Board of Directors which is the earlier of
(i) the tenth day after the Stock Acquisition Date or (ii) the tenth business
day after the date of the commencement by any person (other than an Exempt
Person) of, or the first public announcement of the intent of any Person (other
than an Exempt Person) to commence, a tender or exchange offer upon the
successful consummation of which such Person, together with its Affiliates and

then outstanding shares of Voting Stock of the Company (irrespective of whether
any shares are actually purchased pursuant to any such offer) (the earlier of
such dates being herein referred to as the "Distribution Date"), (x) the Rights
shall be evidenced by the certificates for Common Stock registered in the name
of the holders of Common Stock (together with, in the case of certificates for
Common Stock outstanding as of the Record Date, the Summary of Rights) and not
by separate Rights Certificates and the record holders of such certificates for
Common Stock shall be the record holders of the Rights represented thereby and
(y) each Right shall be transferable only simultaneously and together with the
transfer of a share of Common Stock (subject to adjustment as hereinafter
provided).  Until the Distribution Date (or, if earlier, the Redemption Date or
Final Expiration Date), the surrender for transfer of any certificate for Common
Stock shall constitute the surrender for transfer of the Right or Rights
associated with the Common Stock evidenced thereby, whether or not accompanied
by a copy of the Summary of Rights.

          (c)       Rights shall be issued in respect of all shares of Common
Stock that become outstanding after the Record Date but prior to the earliest of
the Distribution Date, the Redemption Date or the Final Expiration Date and, in
certain circumstances provided in Section 22 hereof, may be issued in respect of
shares of Common Stock that become outstanding after the Distribution Date.
Certificates for Common Stock issued (including, without limitation,
certificates issued upon original issuance, disposition from the Company's
treasury or transfer or exchange of Common Stock) after the Record Date but
prior to the earliest of the Distribution Date, the Redemption Date, or the
Final Expiration Date (or, in certain circumstances as provided in Section 22
hereof, after the Distribution Date) shall have impressed, printed, written or
stamped thereon or otherwise affixed thereto the following legend:

                                        6
<PAGE>
      This certificate also evidences and entitles the holder hereof to
      the same number of Rights (subject to adjustment) as the number of
      shares of Common Stock represented by this certificate, such Rights
      being on the terms provided under the Rights Agreement between
      MedImmune, Inc. and American Stock Transfer & Trust Company (the
      "Rights Agent"), dated as of July 9, 1997, as it may be amended from
      time to time (the "Rights Agreement"), the terms of which are
      incorporated herein by reference and a copy of which is on file at
      the principal executive offices of MedImmune, Inc.  Under certain
      circumstances, as set forth in the Rights Agreement, such Rights
      shall be evidenced by separate certificates and shall no longer be
      evidenced by this certificate.  MedImmune, Inc. shall mail to the
      registered holder of this certificate a copy of the Rights Agreement
      without charge after receipt of a written request therefor.  Under
      certain circumstances as provided in Section 7(e) of the Rights
      Agreement, Rights issued to or Beneficially Owned by Acquiring
      Persons or their Affiliates or Associates (as such terms are defined
      in the Rights Agreement) or any subsequent holder of such Rights
      shall be null and void and may not be transferred to any Person.
      
          (d)       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 mail, postage prepaid, to each record holder of the Common
Stock as of the Close of Business on the Distribution Date, as shown by the
records of the Company, at the address of such holder shown on such records, a
certificate in the form provided by Section 4 hereof (a "Rights Certificate"),
evidencing one Right (subject to adjustment as provided herein) for each share
of Common Stock so held.  As of and after the Distribution Date, the  rights
shall be evidenced solely by Rights Certificates and may be transferred by the
transfer of the Rights Certificate as permitted hereby, separately and apart
from any transfer of one or more shares of Common Stock.

          Section 4.     Form of Rights Certificates.

          The Rights Certificates (and the forms of election to purchase shares,
certificate and assignment to be printed on the reverse thereof), when, as and
if issued, shall be substantially in the form set forth in Exhibit C hereto and
may have such marks of identification or designation and such legends, summaries
or endorsements printed thereon as may be required to comply with any law or
with any rule or regulation made pursuant thereto or with any rule or regulation
of any stock exchange on which the Common Stock or the Rights may from time to
time be listed or as the Company may deem appropriate to conform to usage or
otherwise and as are not inconsistent with the provisions of this Rights
Agreement.  Subject to the provisions of Section 22 hereof, Rights Certificates
evidencing Rights whenever issued (i) shall be dated as of the date of issuance

                                        7
<PAGE>
of the Rights they represent and (ii) subject to adjustment from time to time as
provided herein, on their face shall entitle the holders thereof to purchase
such number of shares (including fractional shares which are integral multiples
of one-hundredth of a share) of Preferred Stock as shall be set forth therein at
the price payable upon exercise of a Right provided by Section 7(b) hereof as
the same may from time to time be adjusted as provided herein (the "Exercise
Price").

          Section 5.     Countersignature and Registration.

          (a)       Each Rights Certificate shall be executed on behalf of the
Company by its Chairman of the Board, President, any Vice President or its
Treasurer, either manually or by facsimile signature.  Each Rights Certificate
shall be countersigned by the Rights Agent manually and shall not be valid for
any purpose unless so countersigned. In case any officer of the Company who
shall have signed any Rights Certificate shall cease to be such officer of the
Company before countersignature by the Rights Agent and issuance and delivery of
the certificate by the Company, such Rights Certificate, nevertheless, may be
countersigned by the Rights Agent and issued and delivered with the same force
and effect as though the person who signed such Rights Certificates had not
ceased to be such officer of the Company.  Any Rights Certificate may be signed
on behalf of the Company by any person who, on the date of the execution of such
Rights Certificate, shall be a proper officer of the Company to sign such Rights
Certificate, although at the date of the execution of this Rights Agreement any
such person was not such an officer.

          (b)       Following the Distribution Date, the Rights Agent will keep
or cause to be kept, at its principal office or one or more offices designated
as the appropriate place for surrender of Rights Certificates upon exercise or
transfer, and in such other locations as may be required by law, books for
registration and transfer of the Rights Certificates issued hereunder.  Such
books shall show the names and addresses of the respective holders of the Rights
Certificates, the number of Rights evidenced on its face by each of the Rights
Certificates and the date of each of the Rights Certificates.

          Section 6.     Transfer, Split Up, Combination and Exchange of Rights
Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates.

          (a)       Subject to the provisions of Sections 7(e), 7(f), 14 and 24
hereof, at any time after the Close of Business on the Distribution Date, and at
or prior to the Close of Business on the earlier of the Redemption Date or the
Final Expiration Date, any Rights Certificate may be (i) transferred or (ii)
split up, combined or exchanged for one or more other Rights Certificates,
entitling the registered holder to purchase a like number of shares of Preferred
Stock as the Rights Certificate or Rights Certificates surrendered then entitled
such holder to purchase.  Any registered holder desiring to transfer any Rights
Certificate shall surrender the Rights Certificate at the office of the Rights
Agent designated for the surrender of Rights Certificates with the form of

                                        8
<PAGE>
certificate and assignment on the reverse side thereof duly endorsed (or
enclosed with such Rights Certificate a written instrument of transfer in form
satisfactory to the Company and the Rights Agent), duly executed by the
registered holder thereof or his attorney duly authorized in writing, and with
such signature duly guaranteed.  Any registered holder desiring to split up,
combine or exchange any Rights Certificate shall make such request in writing
delivered to the Rights Agent, and shall surrender the Rights Certificate to be
split up, combined or exchanged at the office of the Rights Agent designated
therefor.  Thereupon, the Rights Agent shall countersign and deliver to the
person entitled thereto a Rights Certificate or Rights Certificates, as the case
may be, as so requested.  The Company may require payment of a sum sufficient to
cover any Transfer Tax that may be imposed in connection with any transfer,
split up, combination or exchange of any Rights Certificates.

          (b)       Subject to the provisions of Sections 7(e), 7(f), 14 and 24
hereof, upon receipt by the Company and the Rights Agent of evidence reasonably
satisfactory to them of the loss, theft, destruction or mutilation of a Rights
Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to them and, if requested by the Company,
reimbursement to the Company and the Rights Agent of all reasonable expenses
incidental thereto, or upon surrender to the Rights Agent and cancellation of
the Rights Certificate if mutilated, the Company shall issue and deliver a new
Rights Certificate of like tenor to the Rights Agent for delivery to the
registered owner in lieu of the Rights Certificate so lost, stolen, destroyed or
mutilated.

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

          (a)       The Rights shall not be exercisable until, and shall become
exercisable on, the Distribution Date (unless otherwise provided herein,
including, without limitation, the restrictions on exercisability set forth in
Sections 7(e), 23 and 24 hereof).  Except as otherwise provided herein, the
Rights may be exercised, in whole or in part, at any time commencing with the
Distribution Date upon surrender of the Rights Certificate, with the form of
election to purchase and certificate on the reverse side thereof duly executed
(with signatures duly guaranteed), to the Rights Agent at the principal office
of the Rights Agent in New York, New York, together with payment of the Exercise
Price for each Right exercised, subject to adjustment as hereinafter provided,

"Final Expiration Date"), (ii) the date on which the Rights are redeemed as
provided in Section 23 hereof (the "Redemption Date"), (iii) the date on which
such Rights are exchanged as provided in Section 24 hereof or (iv) the time at
which the Rights expire pursuant to Section 13(e) hereof.

          (b)       The Exercise Price shall initially be $100 for each one one-
hundredth (1/100) of a share of Preferred Stock issued pursuant to the exercise
of a Right.  The Exercise Price and the number of shares of Preferred Stock or
other securities to be acquired upon exercise of a Right shall be subject to
adjustment from time to time as provided in Sections 11 and 13 hereof.  The
Exercise Price shall be payable in lawful money of the United States of America,
in accordance with paragraph (c) below.

                                        9
<PAGE>
          (c)       Except as otherwise provided herein, upon receipt of a
Rights Certificate representing exercisable Rights with the form of election to
purchase and the certificate contained therein duly executed, accompanied by
payment by certified check, cashier's check, bank draft or money order payable
to the Company of the Exercise Price for the shares to be purchased and an
amount equal to any applicable Transfer Tax required to be paid by the holder of
the Rights Certificate in accordance with Section 9(e) hereof, the Rights Agent
shall thereupon promptly (i) requisition from any transfer agent of the
Preferred Stock of the Company one or more certificates representing the number
of shares of Preferred Stock to be so purchased, and the Company hereby
authorizes such transfer agent to comply with all such requests, (ii) as
provided in Section 14(b), at the election of the Company, cause depositary
receipts to be issued in lieu of fractional shares of Preferred Stock, (iii) if
the election provided for in the immediately preceding clause (ii) has not been
made, requisition from the Company the amount of cash to be paid in lieu of the
issuance of fractional shares in accordance with section 14(b) hereof, (iv)
after receipt of such Preferred Stock certificates and, if applicable,
depositary receipts, cause the same to be delivered to or upon the order of the
registered holder of such Rights Certificate, registered in such name or names
as may be designated by such holder and (v) when appropriate, after receipt,
promptly deliver such cash to or upon the order of the registered holder of such
Rights Certificate; provided, however, that in the case of a purchase of
securities, other than Preferred Stock, pursuant to Section 13 hereof, the
Rights Agent shall promptly take the appropriate actions corresponding in such
case to that referred to in the foregoing clauses (i) through (v) of this
Section 7(c).  Notwithstanding the foregoing provisions of this Section 7(c),
the Company may suspend the exercisability of the Rights for a period not in
excess of ninety (90) days, during which the Company seeks to register under the
Securities Act of 1933, as amended (the "Act"), and any applicable securities
law of any other jurisdiction, the shares of Preferred Stock to be issued
pursuant to the Rights.

          (d)       In case the registered holder of any Rights Certificate
shall exercise less than all the Rights evidenced thereby, a new Rights
Certificate evidencing Rights equivalent to the Rights remaining unexercised
shall be issued by the Rights Agent to the registered holder of such Rights
Certificate or his assign, subject to the provisions of Section 14(b) hereof.

          (e)       Notwithstanding any provision of this Rights Agreement to
the contrary, from and after the time (the "invalidation time") when any Person
first becomes an Acquiring Person, any Rights that are beneficially owned by (x)
such Acquiring Person (or any Associate or Affiliate of such Acquiring Person),
(y) a transferee of such Acquiring Person (or any such Associate or Affiliate)
who becomes a transferee after the invalidation time or (z) a transferee of such
Acquiring Person (or any such Associate or Affiliate) who becomes a transferee
prior to or concurrently with the invalidation time pursuant to either (I) a
transfer from the Acquiring Person to holders of its equity securities or to any
Person with whom it has any continuing agreement, arrangement or understanding

                                       10
<PAGE>
regarding the transferred Rights or (II) a transfer which the Board of Directors
has determined is part of a plan, arrangement or understanding which has the
purpose or effect of avoiding the provisions of this Section 7(e) and subsequent
transferees of such Persons referred to in clause (y) and (z) above, shall be
void without any further action and any holder of such Rights shall thereafter
have no rights whatsoever with respect to such Rights under any provision of
this Rights Agreement.  The Company shall use all reasonable efforts to ensure
that the provisions of this Section 7(e) are complied with, but shall have no
liability to any holder of Rights Certificates or any other Person as a result
of its failure to make any determination with respect to an Acquiring Person or
its Affiliates, Associates or transferees hereunder.  No Rights Certificate
shall be issued pursuant to Section 3 hereof that represents Rights beneficially
owned by an Acquiring Person whose Rights would be void pursuant to the
provisions of this Section 7(e) or any Associate or Affiliate hereof; no Rights
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 provisions of this
Section 7(e) or any Associate or Affiliate thereof or to any nominee of such
Acquiring Person, Associate or Affiliate; and any Rights Certificate delivered
to the Rights Agent for transfer to an Acquiring Person whose Rights would be
void pursuant to the provisions of this Section 7(e) shall be cancelled.

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

          Section 8.     Cancellation and Destruction of Rights Certificates.

          All Rights Certificates surrendered for the purpose of exercise,
transfer, split up, combination or exchange shall, if surrendered to the Company
or to any of its agents, be delivered to the Rights Agent for cancellation or in
cancelled form, or, if surrendered to the Rights Agent, shall be cancelled by
it, and no Rights 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 cancel and retire, any Rights Certificate purchased or
acquired by the Company otherwise than upon the exercise thereof.  The Rights
Agent shall deliver all cancelled Rights Certificates to the Company, or shall,
at the written request of the Company, destroy such cancelled Rights
Certificates, and in such case shall deliver a certificate of destruction
thereof to the Company.

          Section 9.     Reservation and Availability of Shares of Preferred
Stock.

                                       11
<PAGE>
          (a)       The Company covenants and agrees that it will cause to be
reserved and kept available out of its authorized and unissued shares of
Preferred Stock or out of its authorized and issued shares of Preferred Stock
held in its treasury, such number of shares of Preferred Stock as will from time
to time be sufficient to permit the exercise in full of all outstanding Rights
and, after the occurrence of a Triggering Event, shall, to the extent reasonably
practicable, so reserve and keep available a sufficient number of shares of
Common Stock (and/or other securities) which may be required to permit the
exercise in full of all outstanding Rights.

          (b)       If the Preferred Stock (or, following the occurrence of a
Triggering Event, the Common Stock and/or other securities) is at any time
listed on a national securities exchange or included for quotation on any
transaction reporting system, then so long as the Preferred Stock (and,
following the occurrence of any such Triggering Event, Common Stock and/or other
securities) issuable and deliverable upon exercise of the Rights may be listed
on such exchange or included for quotation on any such transaction reporting
system, the Company shall use its best efforts to cause, from and after such
time as the Rights become exercisable (but only to the extent that it is
reasonably likely that the Rights will be exercised), all shares reserved for
such issuance to be listed on such exchange or included for quotation on any
such transaction reporting system upon official notice of issuance upon such
exercise.

          (c)       The Company covenants and agrees that it will take all such
action as may be necessary to insure that all shares of Preferred Stock
delivered upon the exercise of Rights (or, following the occurrence of a
Triggering Event, shares of Common Stock and/or other securities) shall, at the
time of delivery of the certificates for such shares or other securities
(subject to payment of the Exercise Price in respect thereof), be duly and
validly authorized and issued and fully paid and nonassessable.

          (d)       The Company shall use its best efforts to (i) file, as soon
as practicable following the occurrence of an event described in Section
11(a)(ii), or as soon as is required by law following the Distribution Date, as
the case may be, a registration statement under the Act, with respect to the
securities purchasable upon exercise of the Rights on an appropriate form, (ii)
cause such registration statement to become effective as soon as practicable
after such filing, and (iii) cause such registration statement to remain
effective (with a prospectus at all times meeting the requirements of the Act)
until the earlier of (A) the date as of which the Rights are no longer
exercisable for such securities, and (b) the date of the expiration of the
Rights.  The Company may temporarily suspend, for a period of time not to exceed
ninety (90) days, the exercisability of the Rights in order to prepare and file
a registration statement under the Act and permit it to become effective.  The
Company will also take such action as may be appropriate under, or to ensure
compliance with, the securities or "blue sky" laws of the various states in
connection with the exercisability of the Rights.  Notwithstanding any provision
of this Agreement to the contrary, the Rights shall not be exercisable in any
jurisdiction unless the requisite qualification in such jurisdiction shall have
been obtained and until a registration statement under the Act (if required)
shall have been declared effective.

          (e)       The Company covenants and agrees that it will pay when due
and payable any and all U.S. federal and state Transfer Taxes which may be
payable in respect of the issuance or delivery of the Rights Certificates or of
any shares of Preferred Stock (or, following the occurrence of a Triggering
Event, Common Stock and/or other securities) issued or delivered 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 a
Rights Certificate to a Person other than, or the issuance or delivery of
certificates for Preferred Stock (or, following the occurrence of a Triggering
Event, Common Stock and/or other securities) upon exercise of Rights in a name
other than that of, the registered holder of the Rights Certificate, and the
Company shall not be required to issue or deliver a Rights Certificate or
certificate for Preferred Stock (or, following the occurrence of a Triggering
Event, Common Stock and/or other securities) to a Person other than such
registered holder until any such Transfer Tax shall have been paid (any such
Transfer Tax being payable by the holder of such Rights Certificate at the time
of surrender) or until it has been established to the Company's satisfaction
that no such Transfer Tax is due.

          Section 10.    Preferred Stock Record Date.

          Each Person in whose name any certificate for shares of Preferred
Stock (or Common Stock and/or other securities, as the case may be) is issued
upon the exercise of Rights shall for all purposes be deemed to have become the
holder of record of the securities represented thereby on, and such certificate
shall be dated as of, the date upon which the Rights Certificate evidencing such
Rights was duly surrendered and payment of the Exercise 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 Stock (or Common
Stock and/or other securities, as the case may be) 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 as of, the next succeeding
Business Day on which the applicable transfer books of the Company are open.
Prior to the exercise of the Rights evidenced thereby, the holder of a Rights
Certificate, as such, shall not be entitled to any rights of a stockholder of
the Company with respect to shares for which the Rights shall be exercisable,
including, without limitation, the right to vote, to receive dividends or other
distributions or to exercise any preemptive rights, and shall not be entitled to
receive any notice of any proceedings of the Company, except as provided herein.

          Section 11.    Adjustment of Exercise Price, Number and Kind of Shares
or Number of Rights.

          The Exercise Price, the number and kind of shares which may be
purchased upon exercise of a Right and the number of Rights outstanding are
subject to adjustment from time to time as provided in this Section 11.

                                       13
<PAGE>
               (a)       (i)  In the event the Company shall at any time after
          the date of this Agreement (A) declare a dividend on the Preferred
          Stock payable in Preferred Stock, (B) subdivide the outstanding
          Preferred Stock, (C) combine the outstanding Preferred Stock into a
          smaller number of shares of Preferred Stock or (D) issue any shares of
          its capital stock in a reclassification of the Preferred Stock
          (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 Exercise 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 Stock 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 consideration to be paid upon the exercise of one Right be
          less than the aggregate par value of the shares of capital stock of
          the Company issuable upon exercise of one Right.  If an event occurs
          which would require an adjustment under both this Section 11(a)(i) and
          Section 11(a)(ii) hereof, the adjustment provided for in this Section
          11(a)(i) shall be in addition to, and shall be made prior to, any
          adjustment required pursuant to this Section 11(a)(ii).
          
               (ii)  Subject to Section 24 of this Agreement, in the event that
          any Person (other than an Exempt Person), alone or together with its
          Affiliates and Associates, shall become an Acquiring Person, unless
          the event causing such Person to become an Acquiring Person is an
          acquisition of shares of Common Stock pursuant to a cash tender offer
          made pursuant to Section 14(d) of the Exchange Act for all outstanding
          shares of Common Stock (other than shares of Voting Stock beneficially
          owned by the Person making the offer or by its Affiliates or
          Associates) at a price and on terms determined by at least a majority
          of the Board of Directors to be (a) at a price which is fair to
          stockholders (taking into account all factors which such members of
          the Board deem relevant, including, without limitation, prices which
          could reasonably be achieved if the Company or its assets were sold on
          an orderly basis designed to realize maximum value) and (b) otherwise
          in the best interests of the Company and its stockholders, then,
          except as otherwise provided in this Section 11, each holder of a
          Right, except as provided in Section 7(e) hereof, shall thereafter
          have the right to receive, upon exercise of such Right at a price
          equal to the then current Exercise Price multiplied by the number of
          one one-hundredths of a share of Preferred Stock for which a Right is
          then exercisable, in accordance with the terms of this Agreement and
          in lieu of Preferred Stock, such number of shares of Common Stock of
          
                                       14
<PAGE>
          the Company as shall equal the result obtained by (x) multiplying the
          then current Exercise Price by the number of one one-hundredths of a
          share of Preferred Stock for which a Right is then exercisable and
          dividing that product by (y) 50% of the Fair Market Value of the
          Company's Common Stock (determined pursuant to Section 11(d) hereof)
          on the date of the occurrence of such event; provided, however, that
          if the transaction that would otherwise give rise to the foregoing
          adjustment is also subject to the provisions of Section 13 hereof,
          then only the provisions of Section 13 hereof shall apply and no
          adjustment shall be made pursuant to this Section 11(a)(ii).
          
               (iii)  In lieu of issuing Common Stock in accordance with Section
          11(a)(ii) hereof, the Company may, if the Board of Directors of the
          Company 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 shares of Common Stock which are authorized by the
          Company's Restated 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, the Company shall):  (A) determine the excess of (1) the value
          of the Common Stock issuable upon the exercise of a Right (the
          "Current Value") over (2) the Exercise Price (such excess being
          referred to as the "Spread") and (B) with respect to each Right, make
          adequate provision to substitute for such Common Stock, upon exercise
          of the Rights, (1) cash, (2) a reduction in the Exercise Price, (3)
          other equity securities of the Company (including, without limitation,
          shares or units of shares of any series of preferred stock which the
          Board of Directors of the Company has deemed to have the same value as
          Common Stock (such shares or units of shares of preferred stock are
          herein called "common stock equivalents")), (4) debt securities of the
          Company, (5) other assets or (6) any combination of the foregoing,
          having an aggregate value equal to the Current Value, where such
          aggregate value has been determined by 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 occurrence of an event described
          in Section 11(a)(ii), then the Company shall be obligated to deliver,
          upon the surrender for exercise of a Right and without requiring
          payment of the Exercise Price, Common Stock (to the extent available),
          and then, if necessary, cash, which shares and/or cash have an
          aggregate value equal to the Spread.  If the Board of Directors shall
          determine in good faith that it is likely that sufficient additional
          Common Stock could be authorized for issuance upon exercise in full of
          the Rights, the thirty (30) day period set forth above may be extended
          to the extent necessary, but not more than ninety (90) days after the
          
                                       15
<PAGE>
          occurrence of an event described in Section 11(a)(ii), in order that
          the Company may seek stockholder approval for the authorization of
          such additional shares.  To the extent that the Company determines
          that some action need be taken pursuant to the preceding sentences of
          this Section 11(a)(iii), the Company may suspend the exercisability of
          the Rights until the expiration of any such period, as extended, in
          order to seek any authorization of additional shares and/or to decide
          the appropriate form of distribution to be made pursuant to this
          Section 11(a)(iii) 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 and shall promptly notify the Rights
          Agent of such suspension.  For purposes of this Section 11(a)(iii),
          the value of the Common Stock shall be the Fair Market Value (as
          determined pursuant to Section 11(d) hereof) per share of the Common
          Stock at the Close of Business on the date of the occurrence of an
          event described in Section 11(a)(ii) and the value of any "common
          stock equivalent" shall be deemed to have the same value as the Common
          stock on such date.
          
               (b)       In the event that the Company shall, after the Record
          Date, fix a record date for the issuance of rights, options or
          warrants to all holders of Preferred Stock entitling them (for a
          period expiring within 45 calendar days after such record date) to
          subscribe for or purchase Preferred Stock (or shares having the same
          rights, privileges and preferences as the Preferred Stock ("equivalent
          preferred stock")) or securities convertible into Preferred Stock or
          equivalent preferred stock at a price per share of Preferred Stock or
          equivalent preferred stock (or having a conversion price per share, if
          a security convertible into Preferred Stock or equivalent preferred
          stock) less than the Fair Market Value per share of the Preferred
          Stock (as defined in Section 11(d)) on such record date, the Exercise
          Price to be in effect after such record date shall be determined by
          multiplying the Exercise Price in effect immediately prior to such
          record date by a fraction, the numerator of which shall be the number
          of shares of Preferred Stock outstanding on such record date plus the
          number of shares of Preferred Stock which the aggregate offering price
          of the total number of shares of Preferred Stock and/or the equivalent
          preferred stock so to be offered (and/or the aggregate initial
          conversion price of the convertible securities so to be offered) would
          purchase at such Fair Market Value and the denominator of which shall
          be the number of shares of Preferred Stock outstanding on such record
          date plus the number of additional shares of Preferred Stock and/or
          equivalent preferred stock 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
          
                                       16
<PAGE>
          the aggregate par value of the shares of capital stock of the Company
          issuable upon exercise of one Right.  Preferred Stock 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 Exercise
          Price shall be adjusted to be the Exercise 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 Stock
          (including any such distribution made in connection with a
          consolidation or merger in which the Company is the continuing or
          surviving corporation) or evidences of indebtedness or assets (other
          than a regular quarterly cash dividend or a dividend payable in
          Preferred Stock) or subscription rights or warrants (excluding those
          referred to in Section 11(b) hereof), the Exercise Price to be in
          effect after such record date shall be determined by multiplying the
          Exercise Price in effect immediately prior to such record date by a
          fraction, the numerator of which shall be the Fair Market Value per
          share of the Preferred Stock on such record date, less the Fair Market
          Value of the portion of the assets or evidences of indebtedness so to
          be distributed or of such subscription rights or warrants applicable
          to one share of Preferred Stock and the denominator of which shall be
          the Fair Market Value per share of the Preferred Stock; 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 Exercise Price shall again be adjusted to be the Exercise
          Price which would then be in effect if such record date had not been
          fixed.
          
               (d)       For the purpose of this Rights Agreement, the "Fair
          Market Value" of any share of Preferred Stock, Common Stock or any
          other stock or any Rights or other security or any other property on
          any date shall be determined as provided in this Section 11(d).  In
          the case of a publicly-traded stock or other security, the Fair Market
          Value on any date shall be deemed to be the average of the daily
          closing prices per share of such stock or per unit of such other
          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 Fair Market Value per share of any
          security is determined during a period which includes any date that is
          within 30 Trading Days after (i) the ex-dividend date for a dividend
          or distribution on such security payable in shares of such security or
          securities convertible into shares of such security, or (ii) the
          effective date of any subdivision, split, combination, consolidation,
          reverse stock split or reclassification of such security, then, and in
          
                                       17
<PAGE>
          each such case, the Fair Market Value shall be appropriately adjusted
          by the Board of Directors of the Company to take into account
          ex-dividend or post-effective date trading.  The closing price for any
          day shall be the last sale price, regular way, or, in case no such
          sale takes place on such day, the average of the closing bid and asked
          prices, regular way (in either case, as reported in the applicable
          transaction reporting system with respect to securities listed or
          admitted to trading on the New York Stock Exchange), or, if the
          securities are not listed or admitted to trading on the New York Stock
          Exchange, as reported in the applicable transaction reporting system
          with respect to securities listed on the principal national securities
          exchange on which such security is listed or admitted to trading; or,
          if 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 Quotation System ("NASDAQ") or such other system then in
          use; or, if no bids for such security are 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 such
          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 such security is listed or admitted to
          trading is open for the transaction of business or, if such security
          is not listed or admitted to trading on any national securities
          exchange, a Business Day.  If a security is not publicly held or not
          so listed or traded, "Fair Market Value" shall mean the fair value per
          share of stock or per other unit of such other security, as determined
          in good faith by the Board of Directors of the Company; provided,
          however, that, if the Preferred Stock is not publicly traded, the Fair
          Market Value of a share of Preferred Stock shall be conclusively
          deemed to be the Fair Market Value of a share of Common Stock
          (appropriately adjusted to reflect any stock split, stock dividend or
          similar transaction occurring after the date hereof), multiplied by
          one hundred.  In the case of property other than securities, the "Fair
          Market Value" thereof shall be determined in good faith by the Board
          of Directors of the Company.  Any such determination of Fair Market
          Value shall be described in a statement filed with the Rights Agent
          and shall be binding upon the Rights Agent and the holders of the
          Rights.
          
               (e)       All calculations under this Section 11 shall be made to
          the nearest cent or to the nearest one one-hundredth of a share, as
          the case may be.  No adjustment in the Exercise Price shall be
          required unless adjustment would require an increase or decrease of at
          least 1% in such 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.
          
                                       18
<PAGE>
          Notwithstanding the preceding sentence, 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 mandates the adjustment
          or (ii) the date of the expiration of the right to exercise the
          Rights.
          
               (f)       Irrespective of any adjustment or change in the
          Exercise Price or the number of shares of Preferred Stock issuable
          upon the exercise of the Rights, the Rights Certificates theretofore
          and thereafter issued may continue to express the Exercise Price and
          the number of shares to be issued upon exercise of the Rights as in
          the initial Rights Certificates issued hereunder but, nevertheless,
          shall represent the Rights as so adjusted.
          
               (g)       Before taking any action that would cause an adjustment
          reducing the purchase price per whole share of Preferred Stock upon
          exercise of the Rights below the then par value, if any, of the shares
          of Preferred Stock, the Company shall use its best efforts to 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 non-assessable shares of such Preferred Stock at such
          adjusted purchase price per share.
          
               (h)       If as a result of an adjustment made pursuant to
          Section 11(a) or Section 13(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 Stock, 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 Stock contained in Sections 11(a), (b), (c),
          (e), (f), (g), (i), (j) and (k), and the provisions of Sections 7, 9,
          10, 13 and 14 with respect to the Preferred Stock shall apply on like
          terms to any such other shares.
          
               (i)       Unless the Company shall have exercised its election as
          provided in Section 11(j), upon each adjustment of the Exercise 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
          Exercise Price, that number of one one-hundredths of a share of
          Preferred Stock (calculated to the nearest one one-millionth of a
          share) obtained by (i) multiplying (x) the number of one one-
          hundredths of a share covered by a Right immediately prior to this
          adjustment by (y) the Exercise Price in effect immediately prior to
          such adjustment of the Exercise Price and (ii) dividing the product so
          obtained by the Exercise Price in effect immediately after such
          adjustment of the Exercise Price.
          
                                       19
<PAGE>
               (j)       The Company may elect on or after the date of any
          adjustment of the Exercise Price to adjust the number of Rights, in
          substitution for any adjustment in the number of one one-hundredths of
          a share of Preferred Stock 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-hundredths of a
          share of Preferred Stock 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 Exercise Price in effect immediately prior to adjustment of the
          Exercise Price by the Exercise Price in effect immediately after
          adjustment of the Exercise 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 Exercise Price is adjusted or any day
          thereafter, but, if the Rights Certificates have been issued, shall be
          at least 10 days later than the date of the public announcement.  If
          Rights Certificates have been issued, upon each adjustment of the
          number of Rights pursuant to this Section 11(j), the Company shall, as
          promptly as practicable, cause to be distributed to holders of record
          of Rights Certificates on such record date Rights Certificates
          evidencing, subject to Section 14 hereof, the additional Rights to
          which such holders shall be entitled as a result of such adjustment,
          or, at the option of the Company, shall cause to be distributed to
          such holders of record in substitution and replacement for the Rights
          Certificates held by such holders prior to the date of adjustment, and
          upon surrender thereof, if required by the Company, new Rights
          Certificates evidencing all the Rights to which such holders shall be
          entitled after such adjustment.  Rights Certificates so to be
          distributed shall be issued, executed and countersigned in the manner
          provided for herein and shall be registered in the names of the
          holders of record of Rights Certificates on the record date specified
          in the public announcement.
          
               (k)       Anything in this Section 11 to the contrary
          notwithstanding, the Company shall be entitled to make such reductions
          in the Exercise 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 Stock, issuance wholly
          for cash of any Preferred Stock at less than the current market price,
          issuance wholly for cash of Preferred Stock or securities which by
          their terms are convertible into or exchangeable for Preferred Stock,
          dividends on Preferred Stock payable in Preferred Stock or issuance of
          rights, options or warrants referred to hereinabove in Section 11(b),
          hereafter made by the Company to holders of its Preferred Stock shall
          not be taxable to such stockholders.

<PAGE>
               (l)       In the event that at any time after the date of this
          Agreement and prior to the Distribution Date, the Company shall
          (i) declare or pay any dividend on the Common Stock payable in Common
          Stock or (ii) effect a subdivision, combination or consolidation of
          the Common Stock (by reclassification or otherwise than by payment of
          dividends in Common Stock) into a greater or lesser number of shares
          of Common Stock, then in any such case (A) the number of one one-
          hundredths of a share of Preferred Stock purchasable after such event
          upon proper exercise of each Right shall be determined by multiplying
          the number of one one-hundredths of a share of Preferred Stock so
          purchasable immediately prior to such event by a fraction, the
          numerator of which is the number of shares of Common Stock outstanding
          immediately before such event and the denominator of which is the
          number of shares of Common Stock outstanding immediately after such
          event, and (B) each share of Common Stock outstanding immediately
          after such event shall have issued with respect to it that number of
          Rights which each share of Common Stock outstanding immediately prior
          to such event had issued with respect to it.  The adjustments provided
          for in this Section 11(l) shall be made successively whenever such a
          dividend is declared or paid or such a subdivision, combination or
          consolidation is effected.
          
          Section 12.    Certification of Adjusted Exercise Price or Number of
Shares.

          Whenever an adjustment is made as provided in Section 11 or Section
13, the Company shall (a) promptly prepare a certificate setting forth such
adjustment, and a brief statement of the facts giving rise to such adjustment,
(b) promptly file with the Rights Agent and with each transfer agent for the
Preferred Stock a copy of such certificate and (c) mail a brief summary thereof
to each holder of a Rights Certificate in accordance with Section 25.
Notwithstanding the foregoing sentence, the failure of the Company to make such
certification or give such notice shall not affect the validity of or the force
or effect of the requirement for such adjustment.  Any adjustment to be made
pursuant to Section 11 or Section 13 of this Rights Agreement shall be effective
as of the date of the event giving rise to such adjustment.  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
adjustment unless and until it shall have received such certificate.

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

          (a)       Except for any transaction approved by the Board of
Directors, in the event that, at any time on or after the Stock Acquisition
Date, (x) the Company shall, directly or indirectly, consolidate with, or merge
with and into, any other Person or Persons and the Company shall not be the
surviving or continuing corporation of such consolidation or merger, or (y) any

                                       21
<PAGE>
Person or Persons shall, directly or indirectly, consolidate with, or merge with
and into, the Company, and the Company shall be the continuing or surviving
corporation of such consolidation or merger and, in connection with such
consolidation or merger, all or part of the outstanding shares of Common Stock
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 (z) the Company or
one or more of its Subsidiaries shall, directly or indirectly, sell or otherwise
transfer to any other Person or any Affiliate or Associate of such Person, in
one or more transactions, or the Company or one or more of its Subsidiaries
shall sell or otherwise transfer to any Persons in one or a series of related
transactions, assets or earning power aggregating more than 50% of the assets or
earning power of the Company and its Subsidiaries (taken as a whole), then, on
the first occurrence of any such event (except as may be contemplated by Section
13(e) hereof), proper provision shall be made so that (i) each holder of record
of a Right, except as provided in Section 7(e) hereof, shall thereafter have the
right to receive, upon the exercise thereof and payment of the Exercise Price in
accordance with the terms of this Rights Agreement, such number of shares of
validly issued, fully paid, non-assessable and freely tradable Common Stock of
the Principal Party (as defined herein), not subject to any liens, encumbrances,
rights of first refusal or other adverse claims, as shall, based on the Fair
Market Value of the Common Stock of the Principal Party on the date of the
consummation of such consolidation, merger, sale or transfer, equal twice the
Exercise Price; (ii) such Principal Party shall thereafter be liable for, and
shall assume, by virtue of such consolidation, merger, sale or transfer, all the
obligations and duties of the Company pursuant to this Rights Agreement; (iii)
the term "Company" for all purposes of this Rights Agreement shall thereafter be
deemed to refer to such Principal Party; (iv) such Principal Party shall take
such steps (including, but not limited to, the reservation of a sufficient
number of shares of its Common Stock in accordance with the provisions of
Section 9 hereof) in connection with such consummation as may be necessary to
assure that the provisions hereof shall thereafter be applicable, as nearly as
reasonably may be, in relation to its shares of Common Stock thereafter
deliverable upon the exercise of the Rights; and (v) the provisions of Section
11(a)(ii) hereof shall be of no effect following the occurrence of any event
described in clause (x), (y) or (z) above of this Section 13(a).  The provisions
of this Section 13 shall similarly apply to successive mergers or consolidations
or sales or other transfers.

          (b)       "Principal Party" shall mean

          (i)       in the case of any transaction described in (x) or (y) of
the first sentence of Section 13(a) hereof:  (A) the Person that is the issuer
of the securities into which shares of Common Stock of the Company are changed
or otherwise exchanged or converted in such merger or consolidation, or, if
there is more than one such issuer, the issuer of the Common Stock of which has
the greatest market value or (B) if no securities are so issued, (x) the Person
that is the other party to the merger or consolidation and that survives such
merger or consolidation, or, if there is more than one such Person, the Person
the Common Stock of which has the greatest market value or (y) if the Person
that is the other party to the merger or consolidation does not survive the
merger or consolidation, the Person that does survive the merger or
consolidation (including the Company if its survives); and

                                       22
<PAGE>
          (ii)      in the case of any transaction described in (z) of the first
sentence in Section 13(a), the Person that is the party receiving the greatest
portion of the assets or earning power transferred pursuant to such transaction
or transactions, or, if each Person that is a party to such transaction or
transactions receives the same portion of the assets or earning power so
transferred or if the Person receiving the greatest portion of the assets or
earning power cannot be determined, whichever of such Persons as is the issuer
of Common Stock having the greatest market value of shares outstanding;
provided, however, that in any such case, if the Common Stock of such Person is
not at such time and has not been continuously over the preceding 12-month
period registered under Section 12 of the Exchange Act, and such Person is a
direct or indirect Subsidiary of another Person the Common Stock of which is and
has been so registered, the term "Principal Party" shall refer to such other
Person, or if such Person is a Subsidiary, directly or indirectly, of more than
one Person, the Common Stocks 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 the Common Stock having the greatest market value of shares
outstanding.

          (c)       The Company shall not consummate any consolidation, merger
or sale or transfer of assets or earning power referred to in Section 13(a)
unless the Principal Party shall have a sufficient number of authorized shares
of its Common Stock that have not been issued or reserved for issuance to permit
exercise in full of all Rights in accordance with this Section 13 and 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
Principal Party shall, upon consummation of such consolidation, merger or sale
or transfer of assets or earning power, assume this Rights Agreement in
accordance with Section 13(a) hereof and that all rights of first refusal or
preemptive rights in respect of the issuance of shares of Common Stock of the
Principal Party upon exercise of outstanding Rights have been waived and that
such transaction shall not result in a default by the Principal Party under this
Rights Agreement, and further providing that, as soon as practicable after the
date of any consolidation, merger or sale or transfer of assets or earning power
referred to in Section 13(a) hereof, the Principal Party will:

                    (i)       prepare and file a registration statement under
               the act with respect to the Rights and the securities purchasable
               upon exercise of the Rights on an appropriate form, 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 Act)
               until the date of expiration of the Rights, and similarly comply
               with applicable state securities laws;
               
                    (ii)      use its best efforts to list (or continue the
               listing of) the Rights and the securities purchasable upon
               exercise of the Rights on a national securities exchange or to
               meet the eligibility requirements for quotation on NASDAQ; and
               
                                       23
<PAGE>
                    (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.  In the event that
               any of the transactions described in Section 13(a) hereof shall
               occur at any time after the occurrence of a transaction described
               in Section 11(a)(ii) hereof, the Rights which have not
               theretofore been exercised shall, subject to the provisions of
               Section 7(e) hereof, thereafter be exercisable in the manner
               described in Section 13(a).
               
          (d)       In case the Principal Party which is to be a party to a
transaction referred to in this Section 13 has provision in any of its
authorized securities or in its Certificate of Incorporation or By-laws or other
instrument governing its corporate affairs, which provision would have the
effect of (i) causing such Principal Party to issue, in connection with, or as a
consequence of, the consummation of a transaction referred to in this Section
13, shares of Common Stock of such Principal Party at less than the then Fair
Market Value per share (determined pursuant to Section 11(b) hereof) or
securities exercisable for, or convertible into, Common Stock of such Principal
Party at less than such then Fair Market Value (other than to holders of Rights
pursuant to this Section 13) or (ii) providing for any special tax or similar
payment in connection with the issuance to any holder of a Right of Common Stock
of such Principal Party pursuant to the provisions of this Section 13, then, in
such event, the Company 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 on the benefits intended to be afforded by the
Rights in connection with, or as a consequence of, the consummation of the
proposed transaction.

          (e)       Notwithstanding anything in this Agreement to the contrary,
Section 13 shall not be applicable to a transaction described in subparagraphs
(x) and (y) of Section 13(a) if (i) such transaction is consummated with a
Person or Persons (or a wholly-owned subsidiary of any such Person or Persons)
who acquired shares of Common Stock pursuant to a cash tender offer for all
outstanding shares of Common Stock which complies with the provisions of Section
11(a)(ii) hereof relating to fair price determination by a majority of the Board
of Directors, (ii) the price per share of Common Stock offered in such
transaction is not less than the price per share of Common Stock paid to all
holders of Common Stock whose shares were purchased pursuant to such cash tender
offer and (iii) the form of consideration being offered to the remaining holders
of shares of Common Stock pursuant to such transaction is the same as the form
of consideration paid pursuant to such cash tender offer.  Upon consummation of
any such transaction contemplated by this Section 13(e), all Rights hereunder
shall expire.

          Section 14.    Fractional Rights and Fractional Shares.

                                       24
<PAGE>
          (a)       The Company shall not be required to issue fractions of
Rights or to distribute Rights Certificates which evidence fractional Rights
(i.e., Rights to acquire less than one one-hundredth of a share of Preferred
Stock).  If the Company shall determine not to issue such fractional Rights,
then, in lieu of such fractional Rights, there shall be paid to the holders of
record of the Rights Certificates with regard to which such fractional Rights
would otherwise be issuable, an amount in cash equal to the same fraction of the
Fair Market Value of a whole Right.

          (b)       The Company shall not be required to issue fractions of
shares of Preferred Stock (other than fractions which are integral multiples of
one-hundredth of a share) upon exercise of the Rights or to distribute
certificates which evidence fractional shares (other than fractions which are
integral multiples of one-hundredth of a share).  In lieu of issuing fractions
of shares of Preferred Stock, the Company may, at its election, issue depositary
receipts evidencing fractions of shares 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 of the rights, privileges and preferences to which they would be entitled as
owners of the Preferred Stock.  With respect to fractional shares that are not
integral multiples of one-hundredth of a share, if the Company does not issue
such fractional shares or depositary receipts in lieu thereof, there shall be
paid to the holders of record of Rights Certificates at the time such Rights
Certificates are exercised as herein provided an amount in cash equal to the
same fraction of the Fair Market Value of a share of Preferred Stock.

          (c)       The holder of a Right by the acceptance of a Right expressly
waives his right to receive any fractional Right or any fractional shares of
Preferred Stock (other than fractions which are integral multiples of one one-
hundredth of a share) upon exercise of a Right.

          Section 15.    Rights of Action.

          All rights of action in respect of this Rights Agreement, except the
rights of action given to the Rights Agent in Section 18 hereof, are vested in
the respective registered holders of the Rights Certificates (and, prior to the
Distribution Date, the holders of record of the Common Stock); and any holder of
record of any Rights Certificate (or, prior to the Distribution Date, of the
Common Stock), without the consent of the Rights Agent or of the holder of any
other Rights Certificate (or, prior to the Distribution Date, of the Common
Stock), may, in his or her own behalf and for his or her own benefit, enforce,
and may institute and maintain any suit, action or proceeding against the
Company to enforce, or otherwise act in respect of, his or her right to exercise
the Rights evidenced by such Rights Certificate in the manner provided in such
Rights Certificate and in this 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.

          Section 16.    Agreement of Right Holders.

                                       25
<PAGE>
          Each 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 shall be
          evidenced by the certificates for Common Stock registered in the name
          of the holders of Common Stock (together, as applicable, with the
          Summary of Rights), which certificates for Common Stock shall also
          constitute certificates for Rights, and not by separate Rights
          Certificates, and each Right shall be transferable only simultaneously
          and together with the transfer of shares of Common Stock;
          
               (b)       after the Distribution Date, the Rights Certificates
          are transferable only on the registry books of the Rights Agent if
          surrendered at the office of the Rights Agent designated for such
          purpose, 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 Rights Certificate (or, prior to the
          Distribution Date, the associated Common Stock certificate) is
          registered as the absolute owner thereof and of the Rights evidenced
          thereby (notwithstanding any notations of ownership or writing on the
          Rights Certificates or the associated Common Stock 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 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 its
          inability to perform any of its obligations under this agreement by
          reason of any preliminary or permanent injunction or other order,
          decree or ruling issued by a court of competent jurisdiction or by a
          governmental, regulatory or administrative agency or commission, or
          any statute, rule, regulation or executive order promulgated or
          enacted by any governmental authority, prohibiting or otherwise
          restraining performance of such obligation.
          
          Section 17.    Rights Certificate Holder Not Deemed a Stockholder.

          No holder, as such, of any Rights Certificate shall be entitled to
vote, receive dividends or be deemed for any purpose the holder of Preferred
Stock or any other securities which may at any time be issuable on the exercise
of the Rights represented thereby, nor shall anything contained herein or in any
Rights Certificate be construed to confer upon the holder of any Rights
Certificate, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 25 hereof), or to receive dividends
or subscription rights, or otherwise, until the Right or Rights evidenced by
such Rights Certificate shall have been exercised in accordance with the
provisions hereof.

          Section 18.    Concerning the Rights Agent.

                                       26
<PAGE>
          (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 gross negligence, bad faith or
willful misconduct on the part of the Rights Agent, for anything done or omitted
to be done by the Rights Agent in connection with the acceptance and
administration of this Rights Agreement, including the cost and expenses of
defending against any claim of liability relating to the Rights or this Rights
Agreement.

          (b)       The Rights Agent shall be protected against, 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 Rights Certificate or certificate for Preferred Stock 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.

          Section 19.    Merger or Consolidation of, or Change in Name of, the
Rights Agent.

          (a)       Any corporation into which the Rights Agent or any successor
Rights Agent may be merged or with which it may be consolidated, or any
corporation resulting from any merger or consolidation to which the Rights Agent
or any successor Rights Agent shall be a party, or any corporation succeeding to
the corporate trust or stock transfer business 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 Rights
Certificates shall have been countersigned but not delivered, any such successor
Rights Agent may adopt the countersignature of the predecessor Rights Agent and
deliver such Rights Certificates so countersigned; and in case at that time any
of the Rights Certificates shall not have been countersigned, any successor
Rights Agent may countersign such Rights Certificates either in the name of the
predecessor Rights Agent or in the name of the successor Rights Agent; and in
all such cases such Rights Certificates shall have the full force provided in
the Rights Certificates and in this Rights Agreement.

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

          Section 20.    Duties of Rights Agent.

                                       27
<PAGE>
          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 Rights Certificates by their acceptance thereof shall
be bound:

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

          (b)       Whenever in the performance of its duties under this 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
President, any Vice President, the Treasurer or the Secretary of the Company and
delivered to the Rights Agent.  Any 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 only for its own
gross negligence, bad faith or willful misconduct.

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

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

                                       28
<PAGE>
          (f)       The Company agrees that it will perform, execute,
acknowledge and deliver or cause to be performed, executed, acknowledged and
delivered all such further and other acts, instruments and assurances as may
reasonably be required by the Rights Agent for the carrying out or performing by
the Rights Agent of the provisions of the Rights Agreement.

          (g)       The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from the
Chairman of the Board, the President or any Vice President or 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 to be taken by it in good faith in accordance with
instructions of any such officer.

          (h)       The Rights Agent and any shareholder, director, officer or
employee of the Rights Agent may buy, sell or deal in any of the Rights or other
securities of the 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 the 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
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)       If, with respect to any Rights Certificate surrendered to
the Rights Agent for exercise or transfer, the certificate following the form of
election to purchase set forth on the reverse side of such Rights Certificate
has either not been completed or indicates an affirmative response to clause 1
and/or 2 thereof, the Rights Agent shall not take further action with respect to
the 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 Stock and
the Preferred Stock by registered or certified mail.  The Company may remove the

                                       29
<PAGE>
Rights Agent or any successor Rights Agent (with or without cause) 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 Stock and the Preferred
Stock by registered or certified 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.  Notwithstanding the foregoing provisions of
this Section 21, in no event shall the resignation or removal of a Rights Agent
be effective until a successor Rights Agent shall have been appointed and have
accepted such appointment.  If the Company shall fail to make such appointment
within a period of 30 days after such removal or after it has been notified in
writing of such resignation or incapacity by the resigning or incapacitated
Rights Agent or by the holder of a Rights Certificate (who shall, with such
notice, submit his Rights Certificate for inspection by the Company), then the
incumbent Rights Agent or the holder of record of any Rights Certificate may
apply to any court of competent jurisdiction for the appointment of a new Rights
Agent.  Any successor Rights Agent, whether appointed by the Company or by such
a court, shall be (a) a corporation organized and doing business under the laws
of the United States or of any state thereof, in good standing, which is
authorized under such laws to exercise corporate trust or stock transfer powers
and is subject to supervision or examination in the conduct of its corporate
trust or stock transfer business by federal or state authorities and which has
at the time of its appointment as Rights Agent a combined capital and surplus of
at least $50,000,000 or (b) an Affiliate controlled by a corporation described
in clause (a) of this sentence.  After appointment, the successor Rights Agent
shall be vested with the same powers, rights, duties and responsibilities as if
it had been originally named as Rights Agent without further act or deed, but
the predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose.  Not later
than the effective date of any such appointment, the Company shall file notice
thereof in writing with the predecessor Rights Agent and each transfer agent of
the Common Stock and Preferred Stock, and mail a notice thereof in writing to
the registered holders of the Rights Certificates.  Failure to give any notice
provided for in this Section 21, however, or any defect therein, shall not
affect the legality or validity of the resignation or removal of the Rights
Agent or the appointment of the successor Rights Agent, as the case may be.
Notwithstanding the foregoing provisions, in the event of resignation, removal
or incapacity of the Rights Agent, the Company shall have the authority to act
as the Rights Agent until a successor Rights Agent shall have assumed the duties
of the Rights Agent hereunder.

          Section 22.    Issuance of New Rights 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 Rights
Certificates evidencing Rights in such form as may be approved by its Board of
Directors or Executive Committee thereof to reflect any adjustment or change in
the Exercise Price per share and the number or kind or class of shares of stock
or other securities or property purchasable under the Rights Certificates made
in accordance with the provisions of this Rights Agreement.

          Section 23.    Redemption.

                                       30
<PAGE>
          (a)       The Company may, at its option, but only by the vote of a
majority of the Board of Directors redeem all but not less than all of the then
outstanding Rights, at any time prior to the Close of Business on the earlier of
(i) the tenth day following the Stock Acquisition Date; provided, however, that,
during the time period relating to when the Rights may be redeemed, the Board of
Directors of the Company may extend the time during which the Rights may be
redeemed to be at any time as may be determined by the Board of Directors of the
Company or(ii) the Final Expiration Date, at a redemption price of $.01 per
Right, appropriately adjusted to reflect any stock split, stock dividend or
similar transaction after the date hereof (the "Redemption Price").
Notwithstanding anything contained in this Agreement to the contrary, the Rights
shall not be exercisable after the first occurrence of the event described in
Section 11(a)(ii) until such time as the Company's right of redemption hereunder
has expired.

          (b)       Without any further action and without any notice, the right
to exercise the Rights will terminate at the effective time of the action of the
Board of Directors ordering the redemption of the Rights and the only right
thereafter of the holders of Rights shall be to receive the Redemption Price.
Within 10 days after the effective time of the action of the Board of Directors
ordering the redemption of the Rights, the Company shall give notice of such
redemption to the holders of the then outstanding Rights by mailing such notice
to all such holders at their last addresses as they appear upon the registry
books of the Rights Agent or, prior to the Distribution Date, on the registry
books of the transfer agent for the Common Stock.  Any notice which is mailed in
the manner herein provided shall be deemed given, whether or not the holder
receives the notice; provided, however, that the failure to give, or any defect
in, any such notice shall not affect the validity of such redemption.  Each
notice of redemption will state the method by which the payment of the
Redemption Price will be made.  At the option of the Board of Directors, the
Redemption Price may be paid in cash to each Rights holder or by the issuance of
shares (and, at the Company's election pursuant to Section 14(b) hereof, cash or
depositary receipts in lieu of fractions of shares other than fractions which
are integral multiples of one one-hundredth (1/100) of a share) of Preferred
Stock having a Fair Market Value equal to such cash payment.

          Section 24.    Exchange.

          (a)       By the vote of a majority of the Board of Directors, the
Company may, at its option, at any time after any Person becomes an Acquiring
Person, exchange all or part of the then outstanding and exercisable Rights
(which shall not include Rights which have become void pursuant to Section 7(e)
hereof) for shares of Common Stock at an exchange rate of one share of Common
Stock per Right, appropriately adjusted to reflect any stock split, stock
dividend or similar transaction occurring after the date hereof (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 an
Exempt Person), together with all Affiliates and Associates of such Person,
becomes the Beneficial Owner of 50% or more of any class of voting stock of the
Company then outstanding.

                                       31
<PAGE>
          (b)       Without any further action and without any notice, the right
to exercise the Rights to be so exchanged will terminate at the effective time
of the action of the Board of Directors ordering the exchange and the only right
thereafter of each holder of such Rights shall be to receive that number of
shares of Common Stock equal to the number of such rights held by such holder
multiplied by the Exchange Ratio.  The Company shall promptly give notice of the
exchange to the holders of such Rights then outstanding by mailing such notice
to all such holders at their last addresses as they appear upon the registry
books of the Rights Agent or, prior to the Distribution Date, on the registry
books of the transfer agent for the Common Stock.   Any notice which is mailed
in the manner herein provided shall be deemed given, whether or not the holder
receives the notice; provided, however, that the failure to give, or any defect
in, any such notice shall not affect the validity of such exchange.  Each such
notice shall state the method by which the exchange for rights will be effected
and, in the event of a 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 Section 7(e)
hereof) held by each holder of Rights.

          (c)       In any exchange pursuant to this Section 24, the Company, at
its option, may substitute shares of Preferred Stock for shares of Common Stock
exchangeable for the Rights, at the initial rate of one one-hundredth of a share
of Preferred Stock for each share of Common Stock, as appropriately adjusted to
reflect adjustments in the voting rights of the Preferred Stock pursuant to the
terms thereof, so that the fraction of a share of Preferred Stock delivered in
lieu of each share of Common Stock shall have the same voting rights as one
share of Common Stock.

          (d)       In the event that there shall not be sufficient shares of
Common Stock or Preferred Stock issued but not outstanding or authorized but
unissued to permit any exchange of Rights as contemplated in accordance with
this Section 24, the Company shall either take such action as may be necessary
to authorize additional Common Stock or Preferred Stock for issuance upon
exchange of the Rights or, alternatively, by the vote of a majority of the Board
of Directors with respect to each Right, (i) pay cash in an amount equal to the
Exercise Price, in lieu of issuing Common Stock or Preferred Stock in exchange
therefor, or (ii) issue debt or equity securities, or a combination thereof,
having a value equal to the Current Value (as hereinafter defined) of the Common
Stock or Preferred Stock exchangeable for each such Right, where the value of
such securities shall be determined in good faith by the Board of Directors, or
(iii) deliver any combination of cash, property, Common Stock, Preferred Stock
and/or other securities having a value equal to the Current Value in exchange
for each Right.  The term "Current Value," for purposes of this Section 24,
shall mean the product of the per share market price of the Common Stock
(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 shares of
Common Stock for which the Right otherwise would be exchangeable if there were
sufficient shares available.  To the extent that the Company determines that

                                       32
<PAGE>
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 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 Stock or Preferred Stock 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
shares of Common Stock or to distribute certificates which evidence fractional
shares of Common Stock.  In lieu of such fractional shares of Common Stock, the
Company shall pay to each registered holder of a Rights Certificate with regard
to which a fractional share of Common Stock would otherwise be issuable, an
amount in cash equal to the same fraction of the fair market value of a whole
share of Common Stock.  For the purposes of this paragraph (e), the fair market
value of a whole share of Common Stock shall be the closing price of a share of
Common Stock (as determined pursuant to Section 11(d) hereof) for the Trading
Day immediately prior to the date of exchange pursuant to this Section 24.

          Section 25.    Notice of Proposed Actions.

          (a)       In case the Company, after the Distribution Date, shall
propose (i) to pay any dividend payable in stock of any class to the holders of
its Preferred Stock or to make any other distribution to the holders of its
Preferred Stock (other than a regular quarterly cash dividend), (ii) to offer to
the holders of its Preferred Stock rights or warrants to subscribe for or to
purchase any additional Preferred Stock or shares of stock of any class or any
other securities, rights or options, (iii) to effect any reclassification of its
Preferred Stock (other than a reclassification involving only the subdivision of
outstanding Preferred Stock), (iv) to effect any consolidation or merger with or
into, 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 more than 50% of the assets or earning power of the Company and its
Subsidiaries (taken as a whole) to, any other Person or Persons, or (v) to
effect the liquidation, dissolution or winding up of the Company, then, in each
such case, the Company shall give to each holder of record of a Rights
Certificate, in accordance with Section 26, 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 or transfer, liquidation, dissolution, or winding up
is to take place and the date of participation therein by the holders of record
of Common Stock or Preferred Stock, 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
record of the Preferred Stock 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 record of
Common Stock or Preferred Stock, whichever shall be the earlier.  The failure to
give notice required by this Section 25 or any defect therein shall not affect
the legality or validity of the action taken by the Company or the vote upon any
such action.

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

          Section 26.    Notices.

proposed supplement or amendment is in compliance with the terms of this Section
27, the Rights Agent shall execute such supplement or amendment.

<PAGE>
          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 Rights Certificates (and, prior to the Distribution
Date, the holders of Common Stock in their capacity as holders of the Rights)
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 holders of record of the Rights Certificates
(and, prior to the Distribution Date, the holders of Common Stock in their
capacity as holders of the Rights).

          Section 30.    Determinations and Actions by the Board; etc.

accordance with the preceding sentence, shall (x) be final, conclusive and
binding on the Company, the Rights Agent, the holders of the Rights and all
other parties and (y) not subject any director to any liability to the holders
of the Rights.

          Section 31.    Delaware Contract.

          This Rights Agreement and each Rights Certificate issued hereunder

          MEDIMMUNE, INC., 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 by the Restated Certificate of Incorporation of the
Corporation and in accordance with the provisions of Section 151 of the General
Corporation Law of the State of Delaware, the Board of Directors on July 9, 1997
adopted a resolution providing for the authorization of a series of Preferred
Stock, as follows:

          RESOLVED, that pursuant to the authority granted to and vested in the
Board of Directors of the Corporation (hereinafter called the "Board of
Directors" or the "Board") in accordance with the provisions of the Restated
Certificate of Incorporation, the Board of Directors hereby creates a series of
Preferred Stock, par value $.01 per share (the "Preferred Stock"), of the
Corporation and hereby states the designation and number of shares, and fixes
the relative rights, preferences, and limitations thereof as follows:

          Section 1.     Designation and Amount.  The shares of such series
shall be designated as "Series B Junior Preferred Stock" (the "Series B Junior
Preferred Stock") and the number of shares constituting the Series B Junior
Preferred Stock shall be six hundred thousand (600,000).  Such number of shares
may be increased or decreased by resolution of the Board of Directors; provided,
that no decrease shall reduce the number of shares of Series B Junior 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 B Junior 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 B Junior Preferred Stock with respect to dividends, the holders of
shares of Series B Junior 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 B Junior Preferred Stock, in an amount per share (rounded to the nearest
cent) equal to the greater of (a) $1.00 or (b) subject to the provision for
adjustment hereinafter set forth, 100 times the aggregate per share amount of
all cash dividends, and 100 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 B Junior 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 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 to which holders of shares of Series B Junior 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 B Junior Preferred Stock as provided in paragraph (A) of this Section
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock); provided that, in the
event no dividend or distribution shall have been declared on the Common Stock
during the period between any Quarterly Dividend Payment Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per share on the
Series B Junior 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 B Junior 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 B Junior 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 B
Junior 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 B Junior Preferred Stock entitled to receive payment of a dividend or
distribution declared thereon, which record date shall be not more than 60 days
prior to the date fixed for the payment thereof.

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

          (A)       Subject to the provision for adjustment hereinafter set
forth, each share of Series B Junior Preferred Stock shall entitle the holder
thereof to 100 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 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 B Junior 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 B Junior 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 B Junior 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 B Junior 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 B Junior
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 B Junior 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 B Junior Preferred
     Stock, except dividends paid ratably on the Series B Junior 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 B Junior 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 (as to dividends and upon
     dissolution, liquidation and winding up) to the Series B Junior Preferred
     Stock; or
     
          (iv)      redeem or purchase or otherwise acquire for consideration
     any shares of Series B Junior Preferred Stock, or any shares of stock
     ranking on a parity (either as to dividends or upon liquidation,
     dissolution or winding up) with the Series B Junior 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 Company 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 B Junior
Preferred Stock purchased or otherwise acquired by the Company in any manner
whatsoever shall be retired and cancelled 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 Restated 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, 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 B Junior
Preferred Stock unless, prior thereto, the holders of shares of Series B Junior
Preferred Stock shall have received $100 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, provided that the holders of shares of Series B
Junior Preferred Stock shall be entitled to receive an aggregate amount per
share, subject to the provision for adjustment hereinafter set forth, equal to
100 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 B Junior Preferred Stock, except distributions made ratably on the Series
B Junior 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) 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 B Junior Preferred Stock were entitled immediately
prior to such event under the proviso in clause (1) of the preceding sentence
shall be adjusted by multiplying such amount by a fraction the numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

          Section 7.     Consolidation, Merger, etc.  In case the Corporation
shall enter into any consolidation, merger, combination or other transaction in
which the shares of Common Stock are exchanged for or changed into other stock
or securities, cash and/or any other property, then in any such case each share
of Series B Junior 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 100 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the Corporation shall at any time 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 B Junior 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 B Junior Preferred
Stock shall not be redeemable.

          Section 9.     Rank.  The Series B Junior 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.

          Section 10.    Amendment.  The Restated 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 B Junior
Preferred Stock so as to affect them adversely without the affirmative vote of
the holders of at least a majority of the outstanding shares of Series B Junior
Preferred Stock, voting together as a single class.

          IN WITNESS WHEREOF, this Certificate of Designations is executed on
behalf of the Corporation by its Chairman of the Board and Chief Executive
Officer and attested by its Secretary this ___ day of July __, 1997.

                 UNDER CERTAIN CIRCUMSTANCES AS PROVIDED IN THE
                 RIGHTS AGREEMENT (AS REFERRED TO BELOW), RIGHTS
                  ISSUED TO OR BENEFICIALLY OWNED BY ACQUIRING
               PERSONS OR THEIR AFFILIATES OR ASSOCIATES (AS SUCH
                TERMS ARE DEFINED IN THE RIGHTS AGREEMENT) OR ANY
               SUBSEQUENT HOLDER OF SUCH RIGHTS SHALL BE NULL AND
                 VOID AND MAY NOT BE TRANSFERRED TO ANY PERSON.
                                        
                                 MEDIMMUNE, INC.
                                        
                          SUMMARY OF RIGHTS TO PURCHASE
                         SERIES B JUNIOR PREFERRED STOCK



          On July 9, 1997, the Board of Directors of MedImmune, Inc. (the
"Company") declared a dividend distribution of one preferred stock purchase
right (a "Right") for each outstanding share of Common Stock, par value $.01 per
share (the "Common Stock"), of the Company.  The distribution is payable as of
July 21, 1997 to stockholders of record on that date.  Each Right entitles the
registered holder to purchase from the Company one one-hundredth (1/100) of a
share of preferred stock of the Company, designated as Series B Junior Preferred
Stock (the "Preferred Stock") at a price of $100 per one one-hundredth (1/100)
of a share ("Exercise Price"), subject to adjustment.  The description and terms
of the Rights are set forth in the Amended and Restated Rights Agreement, dated
as of October 31, 1998 (the "Rights Agreement"), between the Company and
American Stock Transfer & Trust Company,  as Rights Agent (the "Rights Agent").

          As discussed below, initially the Rights will not be exercisable,
certificates will not be sent to stockholders and the Rights will automatically
trade with the Common Stock.

          The Rights become exercisable upon the close of business on the day
(the "Distribution Date") which is the earlier of (i) the tenth day following a
public announcement that a person or group of affiliated or associated persons,
with certain exceptions set forth below, has acquired beneficial ownership of
20% or more of any class of the outstanding voting stock of the Company (an
"Acquiring Person") and (ii) the tenth business day after the date of the
commencement or announcement of a person's or group's intention to commence a
tender or exchange offer the consummation of which would result in the ownership
of 20% or more of any class of the Company's outstanding voting stock (even if
no shares are actually purchased pursuant to such offer), or such later date as
may be determined by a majority of the Board of Directors; prior thereto, the
Rights will not be exercisable, will not be represented by a separate
certificate, and will not be transferable apart from the Company's Common Stock,
but will instead be evidenced, with respect to any of the Common Stock
certificates outstanding as of July 21, 1997, by such Common Stock certificate
with a copy of this Summary of Rights attached thereto.  An Acquiring Person
does not include (A) the Company, (B) any subsidiary of the Company, (C) any
employee benefit plan or employee stock plan of the Company or of any subsidiary
of the Company, or any trust or other entity organized, appointed, established
or holding Common Stock for or pursuant to the terms of any such plan or (D) any
person or group whose ownership of 20% or more of the shares of any class of
voting stock of the Company then outstanding results solely from (i) any action
or transaction or transactions approved by a majority of the Board of Directors
before such person or group became an Acquiring Person or (ii) a reduction in
the number of issued and outstanding shares of voting stock of the Company
pursuant to a transaction or transactions approved by a majority of the Board of
Directors (provided that, in the case of the person set forth in clause (D) does
not become an Acquiring Person by reason of clause (i) or (ii) above, such
persons set forth in clause (D) shall nonetheless become an Acquiring Person
upon acquisition of any additional shares of the Company's voting stock unless
such acquisition of additional voting stock will not result in such person or
group becoming an Acquiring Person by reason of such clause (i) or (ii)).

          Until the Distribution Date (or earlier redemption or expiration of
the Rights), new Common Stock certificates issued after July 21, 1997 will
contain a legend incorporating the Rights Agreement by reference.  Until the
Distribution Date (or earlier redemption or expiration of the Rights), the
surrender for transfer of any of the Common Stock certificates outstanding as of
July 21, 1997 with or without a copy of this Summary of Rights attached thereto,
will also constitute the transfer of the Rights associated with the Common Stock
represented by such certificate.  As soon as practicable following the
Distribution Date, separate certificates evidencing the Rights ("Rights
Certificates") will be mailed to holders of record of the Common Stock as of the
close of business on the Distribution Date and such separate certificates alone
will evidence the Rights from and after the Distribution Date.

          The Rights are not exercisable until the Distribution Date.  The
Rights will expire at the close of business on July 9, 2007, unless earlier
redeemed or exchanged by the Company, in each case as described below.

          The Preferred Stock is nonredeemable and, unless otherwise provided in
connection with the creation of a subsequent series of preferred stock,
subordinate to any other series of the Company's preferred stock.  Each share of
Preferred Stock will be entitled to a minimum quarterly dividend payment of
$1.00 per share but will be entitled to an aggregate dividend of 100 times the
dividend declared on the Company's Common Stock.  In the event of the
liquidation of the Company, the holders of Preferred Stock will be entitled to
receive a payment of the greater of (i) $100.00 per share or (ii) 100 times the
payment made per share of Common Stock.  Each share of Preferred Stock will have
100 votes, voting together with the Common Stock.  In the event of any merger,
consolidation or other transaction in which Common Stock is exchanged, each
share of Preferred Stock will be entitled to receive 100 times the amount
received per share of Common Stock.  The rights of Preferred Stock as to
dividends, liquidation and voting are protected by anti-dilution provisions.

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

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

          Unless the transaction is approved by a majority of the Board of
Directors, in the event that, after the time the Rights become exercisable, the
Company were to be acquired in a merger or other business combination (in which
any shares of Common Stock are changed into or exchanged for other securities or
assets) (other than a merger that follows a cash tender offer for all
outstanding shares of the Company, at a price determined by a majority of the
Board of Directors to be fair and otherwise in the best interests of the Company
and its stockholders) or more than 50% of the assets or earning power of the
Company and its subsidiaries (taken as a whole) were to be sold or transferred
in one or a series of related transactions, the Rights Agreement provides that
proper provision will be made so that each holder of record of a Right, will
from and after such date, have the right to receive, upon payment of the
Exercise Price, that number of shares of common stock of the acquiring company
having a market value at the time of such transaction equal to two times the
Exercise Price.  In addition, in the event that a person or group of affiliated
or associated persons becomes an Acquiring Person (unless such acquisition is
made pursuant to a cash tender offer determined to be fair to the stockholders
of the Company, as described in the preceding sentence), the Rights Agreement
provides that proper provision will be made so that each holder of record of a
Right, other than the Acquiring Person (whose Rights will thereupon become null
and void), will thereafter have the right to receive, upon payment of the
Exercise Price, that number of shares of the Common Stock (or cash, other
securities or property) having a market value at the time of the transaction
equal to two times the Exercise Price (such market value to be determined with
reference to the market value of the Company's Common Stock as provided in the
Rights Agreement).

          Fractions of shares of Preferred Stock (other than fractions which are
integral multiples of one one-hundredth of a share) may, at the election of the
Company, be evidenced by depositary receipts.  The Company may also issue cash
in lieu of fractional shares which are not integral multiples of one one-
hundredth of a share.

          At any time on or prior to the close of business on the earlier of (i)
the tenth day after the time that a person (or group of affiliated or associated
persons) has become an Acquiring Person (or such later date as a majority of the
Board of Directors may determine) or (ii) July 9, 2007, the Company may redeem
the Rights in whole, but not in part, at a price of $.01 per Right (the
"Redemption Price"), with the approval of the Board of Directors.  Immediately
upon the effective time of the action of the Board of Directors of the Company
authorizing redemption of the Rights, the right to exercise the Rights will
terminate and the only right of the holders of Rights will be to receive the
Redemption Price.

          For as long as the Rights are then redeemable, the Company may amend
the Rights in any manner, including an amendment to extend the time period in
which the Rights may be redeemed.  At any time when the Rights are not then
redeemable, the Company may amend the Rights in any manner that does not
materially adversely affect the interests of holders of the Rights as such.
Amendments to the Rights Agreement require the approval of the Board of
Directors.

          At any time after a person (or group of affiliated or associated
persons) becomes an Acquiring Person and prior to the acquisition by any such
person or group of 50% or more of any class of outstanding voting stock of the
Company, the Board of Directors of the Company may exchange the Rights (other
than Rights owned by such person or group which have become void), in whole or
in part, at an exchange ratio of one share of Common Stock (or a fraction of a
share of Preferred Stock or other consideration having equivalent market value)
per Right (subject to adjustment).

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

          A copy of the Rights Agreement has been filed with the Securities and
Exchange Commission as an Exhibit to a Registration Statement on Form 8-A/A
dated November  , 1998.  A copy of the Rights Agreement is available free of
charge from the Company.  This summary description of the Rights does not
purport to be complete and is qualified in its entirety by reference to the
Rights Agreement which is incorporated herein by reference.

with the Form of Election to Purchase attached hereto duly executed.

          As provided in the Rights Agreement, the Exercise Price and the number

adjustment upon the happening of certain events and, upon the happening of

property, may be acquired upon exercise of the Rights evidenced by this Rights
Certificate, as provided in the Rights Agreement.

          This Rights Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are

Certificate shall be exercised in part, the holder shall be entitled to receive
upon surrender hereof, another Rights Certificate or Rights Certificates for the
number of whole Rights not exercised.

or in part for shares of the Company's Common Stock, par value $.01 per share,
shares of Preferred Stock or substantially equivalent rights or other
consideration as determined by the Company.

          No fractional shares of Preferred Stock (other than fractions which
are integral multiples of one one-hundredth (1/100) of a share) are required to
be issued upon the exercise of any Right or Rights evidenced hereby, and in lieu
thereof the Company may cause depositary receipts to be issued and/or a cash
payment may be made, as provided in the Rights Agreement.

vote or receive dividends or be deemed for any purpose the holder of Preferred
Stock or of any other securities of the Company which may at any time be
issuable on the exercise hereof, nor shall anything contained in the Rights
Agreement or herein be construed to confer upon the holder hereof, 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 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 the Rights Agreement), or to receive dividends or subscription rights, or
otherwise, until the Right or Rights evidenced by this Rights Certificate shall

purpose until it shall have been countersigned by the Rights Agent.
