  Item 5. Other Events.

     On September 5, 1995, the Board of Directors of ImmuCell Corporation (the
  "Company") declared a dividend of one common share purchase right (a "Right")
  for each of the then outstanding shares of Common Stock, par value $0.10 per
  share, (the "Common Stock") of the Company.  The dividend is payable on
  September 19, 1995 (the "Record Date") to the stockholders of record on that
  date.  Each Right entitles the registered holder to purchase from the Company
  one share of Common Stock of the Company at a price of $70.00 per share (the
  "Purchase Price"), subject to adjustment.  The description and terms of the
  Rights are set forth in a Rights Agreement (the "Rights Agreement") between
  the Company and American Stock Transfer & Trust Co., as Rights Agent (the
  "Rights Agent").

     Until the earlier to occur of (i) 10 days following a public announcement
  that, without the prior consent of the "Continuing Directors" (as such term
  is defined in the Rights Agreement), a person or group of affiliated or
  associated persons has acquired beneficial ownership of 15% or more of the
  outstanding shares of Common Stock (such person being referred to as the
  "Acquiring Person"), or (ii) 10 days (or such later date as may be determined
  by action of the Board of Directors prior to such time as any Person becomes
  an Acquiring Person) following the commencement of, or announcement of an
  intention to make, a tender offer or exchange offer the consummation of which
  would result in the beneficial ownership by a person or group of 20% or more
  of the outstanding shares of Common Stock (the earlier of such dates being
  called the "Distribution Date"), the Rights will be evidenced, with respect
  to any of the Common Stock certificates outstanding as of the Record Date, by
  such Common Stock certificate with a copy of this Summary of Rights attached
  thereto.

     The Rights Agreement provides that, until the Distribution Date, the Rights
  will be transferred with and only with the Common Stock.  Until the
  Distribution Date (or earlier redemption or expiration of the Rights), new
  Common Stock certificates issued after the Record Date, upon transfer or new
  issuance of Common Stock, will contain a notation incorporating the Rights
  Agreement by reference.  Until the Distribution Date (or earlier redemption
  or expiration of the Rights), the surrender for transfer of any certificates
  for Common Stock, outstanding as of the Record Date, even without such
  notification or a copy of this Summary of Rights being 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 ("Right
  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 Right
  Certificates alone will evidence the Rights.

     The Rights are not exercisable until the Distribution Date.  The Rights
  will expire on September 19, 2005 (the "Final Expiration Date"), unless the
  Final Expiration Date is extended or unless the Rights are earlier redeemed
  by the Company, in each case as described below.

     The Purchase Price payable, and the number of shares of Common 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, stock split, combination or
  reclassification of, the Common Stock, (ii) upon the grant to holders of
  Common Stock of certain rights, options or warrants to subscribe for or
<PAGE>

  purchase shares of Common Stock at a price, or securities convertible into
  shares of Common Stock with a conversion price, less than the then current
  market price of the Common Stock or (iii) upon the distribution to holders of
  the Common Stock of evidences of indebtedness, cash (excluding regular
  quarterly or other periodic cash dividends paid out of the earnings or
  retained earnings of the Company), assets, stock (other than dividends
  payable in shares of Common Stock) or of subscription rights or warrants
  (other than those referred to above).

     In the event that, after the Distribution Date, the Company should
  consolidate or merge with and into any other person and the Company is not
  the surviving company, or, if the Company should be the surviving company,
  all or part of the Company's Common Stock is changed or exchanged for
  securities of any other person or if 50% or more of its consolidated assets
  or earning power are sold, proper provision will be made so that each holder
  of a Right will thereafter have the right to receive, upon the exercise
  thereof at the then current Purchase Price, that number of shares of common
  stock of the acquiring company which at the time of such transaction will
  have a market value of two times the Purchase Price.  In the event that any
  person becomes an Acquiring Person, proper provision shall be made so that
  each holder of a Right, other than Rights beneficially owned by the Acquiring
  Person or any Affiliate or Associate of an Acquiring Person (which will
  thereafter be void), will thereafter have the right to receive upon the
  exercise thereof at the then current Purchase Price, that number of shares of
  Common Stock having a market value of two times the Purchase Price; provided,
  however, that Rights are not exercisable following the occurrence of such
  event until such time as the Rights are no longer redeemable by the Company
  as set forth below.

     At any time after a person or group becomes an Acquiring Person and prior
  to the acquisition by such person or group of 50% or more of the outstanding
  Common Stock, 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 per Right
  (subject to adjustment).

     With certain exceptions, no adjustment in the Purchase Price will be
  required until cumulative adjustments require an adjustment of at least 1% in
  such Purchase Price.  No fractional shares of Common Stock will be issued,
  and in lieu thereof, an adjustment in cash may be made based on the market
  price of the Common Stock on the last trading day prior to the date of
  exercise.

     At any time prior to the earlier of fourteen days following the date that
  any person or group becomes an Acquiring Person, (subject to extension by the
  Board of Directors of the Company), or the Final Expiration Date, the Board
  of Directors of the Company may redeem the Rights in whole, but not in part,
  at a price of $.005 per Right (the "Redemption Price"); provided, that if the
  Board authorizes redemption of the Rights after the first date of public
  announcement by the Company or an Acquiring Person that an Acquiring Person
  has become such, there must be Continuing Directors then in office and a
  majority of the Directors of the Board and a majority of the Continuing
  Directors must approve such redemption.  The redemption of the Rights may be
  made effective at such time, on such basis and with such conditions as the
  Board of Directors in its sole discretion may establish.  Immediately upon
  any redemption of the Rights, the right to exercise the Rights will terminate
  and the only right of the holders of Rights will be to receive the Redemption
  Price.
<PAGE>


     Prior to the Distribution Date, the terms of the Rights Agreement may be
  amended by the Board of Directors of the Company without the consent of the
  holders of the Rights or holders of the Common Stock.  From and after the
  Distribution Date, the terms of the Rights Agreement may be amended by the
  Company without the consent of the holders of the Rights or holders of the
  Common Stock in any manner which the Company may deem necessary or desirable
  so long as such supplement or amendment does not adversely affect the
  interest of Rights holders (other than the Acquiring Person or any Associate
  or Affiliates), and provided that such supplement or amendment may not
  lengthen the time period for redemption of the Rights if the Rights are not
  then redeemable and provided that there must be Continuing Directors then in
  office and that a majority of the Board and a majority of the Continuing
  Directors must approve such amendment.  The Company may at any time prior to
  such time as a person or group of affiliated or associated persons becomes an
  Acquiring Person lower the threshold for a person or group becoming an
  Acquiring Person from 15% to not less than the greater of (i) any percentage
  greater than the largest percentage of the outstanding shares of Common Stock
  then known to the Company to be beneficially owned by any such person or
  group of affiliated or associated persons and (ii) 10%.  In no case shall any
  amendment or supplement at any time decrease the Redemption Price or the
  period of time remaining until the Final Expiration Date.

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

     A copy of the Rights Agreement between the Company and American Stock
  Transfer & Trust Co., as Rights Agent, is attached hereto as an exhibit and
  is incorporated herein by reference.  The foregoing description of the Rights
  is qualified in its entirety by reference to the Rights Agreement.

  Exhibit A - Form of Right Certificate

  Exhibit B - Summary of Rights to Purchase Common Stock
<PAGE>

  RIGHTS AGREEMENT

       Agreement, dated as of September 5, 1995, between ImmuCell
  Corporation, a Delaware corporation (the "Company"), and American
  Stock Transfer & Trust Co., a New York corporation (the "Rights
  Agent").

       The Board of Directors of the Company (the "Board") has
  authorized and declared a dividend of one share purchase right (a
  "Right") for each share of Common Stock (as hereinafter defined)
  of the Company outstanding on September 19, 1995 (the "Record
  Date"),  each Right representing the right to purchase one share
  of Common Stock (as hereinafter defined), upon the terms and
  subject to the conditions herein set forth, and has further
  authorized and directed the issuance of one Right with respect to
  each share of Common Stock that shall become outstanding between
  the Record Date and the earlier of the Distribution Date, the
  Redemption Date and the Final Expiration Date (as such terms are
  hereinafter defined).

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

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

       (a)  "Acquiring Person" shall mean any Person (as such term
  is hereinafter defined) who or which, together with all
  Affiliates and Associates (as such terms are hereinafter defined)
  of such Person, without the prior approval of a majority of the
  "Continuing Directors" (as such term is hereinafter defined),
  shall be the Beneficial Owner (as such term is hereinafter
  defined) of 15% or more of the Common Stock of the Company then
  outstanding, but shall not include the Company or any Related
  Person (as such term is hereinafter defined).  Notwithstanding
  the foregoing, no Person shall become an "Acquiring Person" as
  the result of an acquisition of Common Stock by the Company
  which, by reducing the number of shares outstanding, increases
  the proportionate number of shares beneficially owned by such
  Person to 15% or more of the Common Stock of the Company then
  outstanding; provided, however, that if a Person shall become the
  Beneficial Owner of 15% or more of the Common Stock of the
  Company then outstanding by reason of share purchases by the
  Company and shall, after such share purchases by the Company,
  become the Beneficial Owner of any additional Common Stock of the
  Company, then such Person shall be deemed to be an "Acquiring
  Person".  Notwithstanding the foregoing, if the Board of
  Directors of the Company determines in good faith that a Person
  who would otherwise be an "Acquiring Person", as defined pursuant
  to the foregoing provisions of this paragraph (a), has become
  such inadvertently, and such Person divests as promptly as
  practicable a sufficient number of 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 to be an "Acquiring Person" for
  any purposes of this Agreement.

       (b)  "Affiliate" and "Associate" shall have the respective
<PAGE>

  meanings ascribed to such terms in Rule 12b-2 of the General
  Rules and Regulations as in effect on the date of this Agreement
  under the Securities Exchange Act of 1934, as amended (the
  "Exchange Act").

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

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

            (ii) which such Person or any of such Person's
       Affiliates or Associates has (A) the right to acquire
       (whether such right is exercisable immediately or only after
       the passage of time) pursuant to any agreement, arrangement
       or understanding (other than customary agreements with and
       between underwriters and selling group members with respect
       to a bona fide public offering of securities), or upon the
       exercise of conversion rights, exchange rights, rights
       (other than these Rights), warrants or options, or
       otherwise; provided, however, that a Person shall not be
       deemed the Beneficial Owner of, or to beneficially own,
       securities tendered pursuant to a tender or exchange offer
       made by or on behalf of such Person or any of such Person's
       Affiliates or Associates until such tendered securities are
       accepted for purchase or exchange; or (B) the right to vote
       any security of the Company or of any Subsidiary of the
       Company pursuant to any agreement, arrangement or
       understanding; provided, however, that a Person shall not be
       deemed the Beneficial Owner of, or to beneficially own, any
       security if the agreement, arrangement or understanding to
       vote such security (1) arises solely from a revocable proxy
       or consent given to such Person in response to a public
       proxy or consent solicitation made pursuant to, and in
       accordance with, the applicable rules and regulations
       promulgated under the Exchange Act and (2) is not also then
       reportable on Schedule 13D under the Exchange Act (or any
       comparable or successor report); or 

            (iii)  which are beneficially owned, directly or
       indirectly, by any other Person with which such Person or
       any of such Person's Affiliates or Associates has any
       agreement, arrangement or understanding (other than
       customary agreements with and between underwriters and
       selling group members with respect to a bona fide public
       offering of securities) for the purpose of acquiring,
       holding, voting (except to the extent permitted by Section
       1(c)(ii)(B)) or disposing of any securities of the Company.

       Notwithstanding anything in this definition of Beneficial
  Ownership to the contrary, (1) the phrase "then outstanding,"
  when used with reference to a Person's Beneficial Ownership of
  securities of the Company, shall mean the number of such
  securities then issued and outstanding together with the number
  of such securities not then actually issued and outstanding which
  such Person would be deemed to own beneficially hereunder and (2)
  a Person engaged in business as an underwriter of securities
<PAGE>

  shall not be deemed the Beneficial Owner of any securities
  acquired through such Person's participation in good faith in an
  underwriting syndicate pursuant to an agreement to which the
  Company is a party until the expiration of 40 calendar days after
  the date of such expiration or such later date as the Board may
  determine in any specific case.

       (d)  "Business Day" shall mean any day other than a
  Saturday, a Sunday, or a day on which banking institutions in the
  State of Maine or the State of New York (or such other state in
  which the principal office of the Rights Agent is located) are
  authorized or obligated by law or executive order to close.

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

       (f)  "Common Stock" when used with reference to the Company
  shall mean the shares of common stock, par value $0.10 per share,
  of the Company or any of the shares of the capital stock of the
  Company into which such stock shall be reclassified or changed. 
  "Common Stock" when used with reference to any Person other than
  the Company shall mean the capital stock (or equity interest)
  with the greatest voting power of such other Person or, if such
  other Person is a Subsidiary of another Person, the Person or
  Persons which ultimately control such first-mentioned Person.

       (g)  "Continuing Director" shall mean any member of the
  Board while such person is a member of the Board who (i) is not
  an Acquiring Person or an Affiliate or Associate of an Acquiring
  Person and (ii) either was (A) a member of the Board prior to the
  Stock Acquisition Date (as such term is hereinafter defined) or
  (B) nominated for his or her initial term of office by a majority
  of the Continuing Directors in office at the time of such
  nomination.

       (h)  "Distribution Date" shall mean the earlier of (i) the
  tenth day after the Stock Acquisition Date or (ii) the tenth day
  (or such later date as may be determined by action of the Board
  prior to such time as any Person becomes an Acquiring Person)
  after the date of the commencement of, or the first public
  announcement of the intent of any Person (other than the Company
  or a Related Person) to commence, a tender or exchange offer (as
  determined by reference to Rule 14d-2(a) under the Exchange Act)
  the consummation of which would result in any Person or Persons
  becoming the Beneficial Owner of Common Stock aggregating 20% or
  more of the then outstanding shares of Common Stock (including
  any such date which is after the date of this Agreement and prior
  to the issuance of the Rights).

       (i)  "Final Expiration Date" shall mean the Close of
  Business on September 19, 2005.

       (j)  "Person" shall mean any individual, partnership,
  limited partnership, joint venture, syndicate, sole
  proprietorship, company or corporation with or without share
  capital, unincorporated association, trust, trustee, executor,
<PAGE>

  administrator or other legal personal representative, regulatory
  body or agency, government or governmental agency, authority or
  entity however designated or constituted, and shall include any
  successor (by merger or otherwise) of any of the foregoing.

       (k)  "Purchase Price" shall mean initially $70.00 per share
  of Common Stock and shall be subject to adjustment from time to
  time as provided in this Agreement.

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

       (m)  "Related Person" shall mean (i) any Subsidiary of the
  Company, (ii) any employee benefit or stock ownership plan of the
  Company or any of its Subsidiaries or (iii) any entity holding
  Common Stock for or pursuant to the terms of any such plan.

       (n)  "Stock Acquisition Date" shall mean the first date of
  public announcement by the Company or an Acquiring Person or an
  Affiliate or Associate of an Acquiring Person by press release,
  filing made with the Securities and Exchange Commission or
  otherwise, that an Acquiring Person has become such.

       (o)  "Subsidiary" of any Person (including the Company)
  shall mean any corporation or other entity of which a majority of
  the voting power of the voting equity securities or equity
  interest is owned, directly or indirectly, by such Person.

       Section 2.  Appointment of Rights Agent.  The Company hereby
  appoints the Rights Agent to act as agent for the Company and the
  holders of the Rights (who, in accordance with Section 3 hereof,
  shall, prior to the Distribution Date, also be the holders of the
  Common Stock) 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.  Contemporaneously with such
  appointment, if any, the Company shall notify the Rights Agent
  thereof.  Any actions which may be taken by the Rights Agent
  pursuant to the terms of this Agreement may be taken by any such
  Co-Rights Agent.

       Section 3.  Issue of Right Certificates.  (a) Until the
  Distribution Date, (i) the Rights will be evidenced (subject to
  the provisions of Section 3(b) hereof) by the certificates for
  Common Stock registered in the names of the holders thereof
  (which certificates for Common Stock shall also be deemed to be
  Right Certificates) and not by separate Right Certificates, and
  (ii) the right to receive Right Certificates will be transferable
  only in connection with the transfer of Common Stock in the share
  transfer books of the Company maintained by the Company or its
  appointed transfer agent.  As soon as practicable after the
  Distribution Date, the Company will prepare and execute, the
  Rights Agent at the request of the Company will countersign, and
  the Company will send or cause to be sent (and the Rights Agent
  will, if requested, send) by first-class, insured, postage-
  prepaid mail to each record holder of Common Stock as of the
  Close of Business on the Distribution Date, at the address of
  such holder shown on the records of the Company, a Right
<PAGE>

  Certificate, in substantially the form of Exhibit A hereto (a
  "Right Certificate"), evidencing one Right for each share of
  Common Stock so held, subject to adjustment as provided herein,
  together with a notice setting forth the Purchase Price as in
  effect on the Distribution Date.  As of the Distribution Date,
  the Rights will be evidenced solely by such Right Certificates.

       (b)  On the Record Date, or as soon as practicable
  thereafter, the Company will send a copy of a Summary of Rights
  to Purchase Common Stock, in substantially the form of Exhibit B
  hereto (the "Summary of Rights"), by first-class, postage-
  prepaid mail, to each record holder of 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 as of such date.  With
  respect to certificates for Common Stock outstanding as of the
  Record Date, until the Distribution Date the Rights will be
  evidenced by such certificates registered in the names of the
  holders thereof together with a copy of the Summary of Rights
  attached thereto.  Until the Distribution Date (or the earlier of
  the Redemption Date or the Final Expiration Date), the surrender
  for transfer of any certificate for Common Stock outstanding on
  the Record Date, with or without a copy of the Summary of Rights
  attached thereto, shall also constitute the transfer of the
  Rights associated with the Common Stock represented thereby.

       (c)  Certificates for Common Stock which become outstanding
  (including, without limitation, reacquired Common Stock referred
  to in the last sentence of this paragraph (c)) after the Record
  Date but prior to the earlier of the Distribution Date, the
  Redemption Date or the Final Expiration Date shall have impressed
  on, printed on, written on or otherwise affixed to them the
  following legend:

            This certificate also evidences and entitles
            the holder hereof to certain rights as set 
            forth in a Rights Agreement between ImmuCell
            Corporation and  American Stock Transfer &
            Trust Co., dated as of September 5, 1995 (the
            "Rights Agreement"), the terms of which are
            hereby incorporated herein by reference and a
            copy of which is on file at the principal
            executive offices of ImmuCell Corporation. 
            Under certain circumstances, as set forth in
            the Rights Agreement, such Rights may be
            redeemed, may expire, may be amended, may be
            exchanged, or may be evidenced by separate
            certificates and will no longer be evidenced
            by this certificate.  ImmuCell Corporation
            will mail to the holder of this certificate a
            copy of the Rights Agreement without charge
            after receipt of a written request therefor. 
            As described in the Rights Agreement, Rights
            issued to any Person who becomes an Acquiring
            Person or any Associate or Affiliate thereof
            (as defined in the Rights Agreement) and
            certain subsequent holders of such Rights
            shall become null and void.
<PAGE>

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

       Section 4.  Form of Right Certificates.  The Right
  Certificates (and the forms of election to purchase Common Stock
  and of assignment to be printed on the reverse thereof) shall be
  substantially the same as Exhibit A hereto and may have such
  marks of identification or designation and such legends,
  summaries or endorsements printed thereon as the Company may deem
  appropriate and as are not inconsistent with the provisions of
  this Agreement or as may be required to comply with any
  applicable law or with any rule or regulation made pursuant
  thereto or with any rule or regulation of any stock exchange or
  relating to any transaction reporting system on which the Common
  Stock or the Rights may from time to time be listed or quoted, or
  to conform to usage.  Subject to the provisions of Section 22
  hereof, the Right Certificates shall entitle the holders thereof
  to purchase such number of shares of Common Stock as shall be set
  forth therein at the Purchase Price per share, but the number of
  such shares and the Purchase Price shall be subject to adjustment
  as provided herein.

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

       Following the Distribution Date, the Rights Agent will keep
  or cause to be kept, at its office designated for such purpose,
<PAGE>

  books for registration and transfer of the Right Certificates
  issued hereunder.  Such books shall show the names and addresses
  of the respective holders of the Right Certificates, the number
  of Rights evidenced on its face by each of the Right Certificates
  and the date of each of the Right Certificates.

       Section 6.  Transfer, Split Up, Combination and Exchange of
  Right Certificates; Mutilated, Destroyed, Lost or Stolen Right
  Certificates.  Subject to the provisions of Section 14 hereof, at
  any time after the Close of Business on the Distribution Date,
  and at or prior to the Close of Business on the earlier of the
  Redemption Date or the Final Expiration Date, any Right
  Certificate or Right Certificates (other than Right Certificates
  representing Rights that have become void pursuant to Section
  11(a)(ii) hereof or that have been exchanged pursuant to Section
  24 hereof) may be transferred, split up, combined or exchanged
  for another Right Certificate or Right Certificates, entitling
  the registered holder to purchase a like number of shares of
  Common Stock as the Right Certificate or Right Certificates
  surrendered then entitled such holder to purchase.  Any
  registered holder desiring to transfer, split up, combine or
  exchange any Right Certificate or Right Certificates shall make
  such request in writing delivered to the Rights Agent, and shall
  surrender the Right Certificate or Right Certificates to be
  transferred, split up, combined or exchanged at the office of the
  Rights Agent designated for such purpose.  Thereupon the Rights
  Agent shall countersign and deliver to the person entitled
  thereto a Right Certificate or Right Certificates, as the case
  may be, as so requested.  The Company may require payment of a
  sum sufficient to cover any tax or governmental charge that may
  be imposed in connection with any transfer, split up, combination
  or exchange of Right Certificates.

       Upon receipt by the Company and the Rights Agent of evidence
  reasonably satisfactory to them of the loss, theft, destruction
  or mutilation of a Right Certificate (other than Right
  Certificates representing Rights that have become null and void
  pursuant to Section 11(a)(ii) hereof or that have been exchanged
  pursuant to Section 24 hereof), and, in case of loss, theft or
  destruction, of indemnity or security reasonably satisfactory to
  them, and, at the Company's request, reimbursement to the Company
  and the Rights Agent of all reasonable expenses incidental
  thereto, and upon surrender to the Rights Agent and cancellation
  of the Right Certificate if mutilated, the Company will make and
  deliver a new Right Certificate of like tenor to the Rights Agent
  for delivery to the registered holder in lieu of the Right
  Certificate so lost, stolen, destroyed or mutilated.

       Section 7.  Exercise of Rights; Purchase Price; Expiration
  Date of Rights.  (a) Except as otherwise provided herein
  (including, without limitation, the restrictions on
  exercisability set forth in Section 23(b) hereof), the registered
  holder of any Right Certificate may exercise the Rights evidenced
  thereby in whole or in part at any time after the Distribution
  Date upon surrender of the Right Certificate, with the form of
  election to purchase on the reverse side thereof duly executed,
  to the Rights Agent at the office of the Rights Agent designated
  for such purpose, together with payment of the Purchase Price for
<PAGE>

  each share of Common Stock as to which the Rights are exercised,
  at or prior to the earlier of (i) the Final Expiration Date, (ii)
  the time at which the Rights are redeemed as provided in Section
  23 hereof (the "Redemption Date"), or (iii) the time at which
  such Rights are exchanged as provided in Section 24 hereof.

       (b)  The Purchase Price for each share of Common Stock
  pursuant to the exercise of a Right shall initially be $70.00,
  shall be subject to adjustment from time to time as provided in
  Sections 11 and 13 hereof, and shall be payable in lawful money
  of the United States of America in accordance with paragraph (c)
  below.

       (c)  Upon receipt of a Right Certificate representing
  exercisable Rights, with the form of election to purchase duly
  executed, accompanied by payment of the Purchase Price for the
  shares to be purchased and an amount equal to any applicable
  transfer tax required to be paid by the holder of such Right
  Certificate in accordance with Section 9 hereof, in cash, or by
  certified check, cashier's check or money order payable to the
  order of the Company, the Rights Agent shall thereupon promptly
  (i) requisition from any transfer agent of the Common Stock
  certificates for the number of shares of Common Stock to be
  purchased and the Company hereby irrevocably authorizes its
  transfer agent to comply with all such requests, (ii) when
  appropriate, requisition from the Company the amount of cash to
  be paid in lieu of issuance of fractional shares in accordance
  with Section 14 hereof, (iii) promptly after receipt of such
  certificates, cause the same to be delivered to or upon the order
  of the registered holder of such Right Certificate, registered in
  such name or names as may be designated by such holder, and (iv)
  when appropriate, after receipt, promptly deliver such cash to or
  upon the order of the registered holder of such Right
  Certificate.

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

       (e)  Notwithstanding anything in this Agreement to the
  contrary, neither the Rights Agent nor the Company shall be
  obligated to undertake any action with respect to a registered
  holder of Rights upon the occurrence of any purported exercise as
  set forth in this Section 7 unless the form of election to
  purchase on the reverse side of the Right Certificate surrendered
  for such exercise shall have been completed and signed by the
  registered holder thereof.

       Section 8.  Cancellation and Destruction of Right
  Certificates.  All Right Certificates surrendered for the purpose
  of exercise, transfer, split up, combination or exchange shall,
  if surrendered to the Company or to any of its agents, be
  delivered to the Rights Agent for cancellation or in cancelled
  form, or, if surrendered to the Rights Agent, shall be cancelled
<PAGE>

  by it, and no Right Certificates shall be issued in lieu thereof
  except as expressly permitted by any of the provisions of this
  Rights Agreement.  The Company shall deliver to the Rights Agent
  for cancellation and retirement, and the Rights Agent shall so
  cancel and retire, any other Right Certificate purchased or
  acquired by the Company otherwise than upon the exercise thereof. 
  The Rights Agent shall deliver all cancelled Right Certificates
  to the Company, or shall, at the written request of the Company,
  destroy such cancelled Right Certificates, and in such case shall
  delivery a certificate of destruction thereof to the Company.

       Section 9.  Company Covenants Concerning Shares and Rights. 
  The Company covenants and agrees that, from and after the
  Distribution Date, it will cause to be reserved and kept
  available out of its authorized and unissued Common Stock, or any
  Common Stock held in its treasury, the number of shares of Common
  Stock that will be sufficient to permit the exercise in full of
  all outstanding Rights in accordance with Section 7 hereof; such
  number of shares of Common Stock reserved and kept available
  shall be adjusted from time to time, if and to the extent
  required, upon the occurrence of any of the events described in
  Sections 11 or 13 hereof.

       In the event that the number of shares of Common Stock which
  is authorized by the Company's certificate of incorporation but
  not outstanding or reserved for issuance for purposes other than
  upon exercise of the Rights is not sufficient to permit the
  exercise in full of a Right in accordance with Section 7, the
  Company shall, within thirty days after the surrender of such
  Right, and to the extent permitted by applicable law and any
  material agreements in effect on the date hereof to which the
  Company is a party:  (A) with respect to each Right, upon
  exercise of such Right, issue shares of Common Stock to the
  extent available for the exercise in full of such Right and, to
  the extent shares of Common Stock are not so available, make
  adequate provision to substitute for the Common Stock in question
  not received upon exercise of such Right (1) other equity
  securities of the Company which are deemed in good faith by the
  Board of Directors to have substantially the same value as shares
  of Common Stock (such other equity securities are herein called
  "common stock equivalents"), (2) debt securities of the Company,
  (3) other assets, or (4) any combination of the foregoing, having
  a value which, when added to the value of the shares of Common
  Stock actually issued upon exercise of such Right, shall have an
  aggregate value equal to the then current value of the Common
  Stock issuable upon the exercise of a Right, where such aggregate
  value has been determined in good faith by the Board of Directors
  based upon the advice of a nationally recognized independent
  investment banking firm selected in good faith by the Board of
  Directors.  If the Board of Directors shall determine in good
  faith that it is likely that sufficient additional shares of
  Common Stock could be authorized for issuance upon exercise in
  full of the Rights, the thirty day period set forth above may be
  extended to the extent necessary, but no more than ninety days
  after the surrender of the Right, in order that the Company may
  seek shareholder approval for the authorization of such
  additional shares (such thirty day period, as it may be extended,
  is herein called the "Substitution Period").  To the extent that
<PAGE>

  the Company determines that some action must be taken pursuant to
  the first and/or second sentence of this paragraph, the Company
  (x) shall provide, subject to the last sentence of this
  paragraph, that such action shall apply uniformly to all
  outstanding Rights, and (y) may suspend the exercisability of the
  Rights until the expiration of the Substitution Period in order
  to seek any authorization of additional shares and/or to decide
  the appropriate form of distribution to be made pursuant to such
  first sentence and to determine the value thereof.  In the event
  of any such suspension, the Company shall issue a public
  announcement stating that the exercisability of the Rights has
  been temporarily suspended, as well as a public announcement at
  such time as the suspension is no longer in effect.  For purposes
  of this paragraph, the value of a share of Common Stock shall be
  the current per share market price of the Common Stock on the
  date that a Right is exercised pursuant to Section 7 and the per
  share or per unit value of any common stock equivalent shall be
  deemed to equal the current per share market price of the Common
  Stock on such date.  The Board of Directors may, but shall not be
  required to, establish procedures to allocate the right to
  receive Common Stock upon the exercise of the Rights among
  holders of the Rights pursuant to this paragraph.

       So long as the shares of Common Stock and/or other
  securities as provided herein issuable and deliverable upon the
  exercise of the Rights may be listed on a national securities
  exchange, the Company covenants and agrees that it will endeavor
  to cause, from and after such time as the Rights become
  exercisable, all securities reserved for such issuance to be
  listed on such exchange upon official notice of issuance.

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

       The Company further covenants and agrees that it will, if
  required by law, use its best efforts to (i) file on an
  appropriate form, as soon as practicable following the
  Distribution Date, a registration statement under the Securities
  Act with respect to the securities purchasable upon exercise of
  the Rights, (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 Final
  Expiration Date.  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.  The Company may
  temporarily suspend the exercisability of the Rights in order to
  prepare and file such registration statement and permit it to
  become effective, and, upon any such suspension, the Company will
  issue a public announcement stating that the exercisability of
<PAGE>

  the Rights has been temporarily suspended, as well as a public
  announcement at such time as the suspension is no longer in
  effect.  

       Notwithstanding anything in this Agreement to the contrary,
  the Company further covenants and agrees that, after the
  Distribution Date, it will not, except as permitted by Section 23
  or Section 27 hereof, take (or permit any Subsidiary to take) any
  action if at the time such action is taken it is reasonably
  foreseeable that such action will diminish or otherwise eliminate
  the benefits intended to be afforded by the Rights.

       In the event that the Company is obligated to issue other
  securities of the Company, pay cash and/or distribute other
  property pursuant to Sections 11, 13 and 14 hereof, the Company
  further covenants and agrees that it will make all arrangements
  necessary so that such other securities, cash and/or property are
  available for distribution by the Rights Agent, if and when
  appropriate.

       Section 10.  Common Stock Record Date.  Each person in whose
  name any certificate for Common Stock is issued upon the exercise
  of Rights shall for all purposes be deemed to have become the
  holder of record of the Common Stock represented thereby on, and
  such certificate shall be dated, the date upon which the Right
  Certificate evidencing such Rights was duly surrendered and
  payment of the Purchase Price (and any applicable transfer taxes)
  was made; provided, however, that if the date of such surrender
  and payment is a date upon which the share transfer books of the
  Company are closed, such person shall be deemed to have become
  the record holder of such shares on, and such certificate shall
  be dated, the next succeeding Business Day on which the share
  transfer books of the Company are open.  Prior to the exercise of
  the Rights evidenced thereby, the holder of a Right Certificate
  shall not be entitled to any rights of a holder of Common Stock
  for which the Rights shall be exercisable, including, without
  limitation, the right to vote, to receive dividends or other
  distributions or to exercise any preemptive rights, and shall not
  be entitled to receive any notice of any proceedings of the
  Company, except as provided herein.

       Section 11.  Adjustment of Purchase Price, Number of Shares
  or Number of Rights.  The Purchase Price, the number of shares of
  Common Stock covered by each Right and the number of Rights
  outstanding are subject to adjustment from time to time as
  provided in this Section 11.

       (a)(i)  In the event the Company shall at any time after the
  date of this Agreement (A) declare a dividend on the Common Stock
  payable in Common Stock, (B) subdivide the outstanding shares of
  Common Stock, (C) combine the outstanding shares of Common Stock
  into a smaller number of shares of Common Stock, or (D) issue any
  shares of its capital stock in a reclassification of the Common
  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 Purchase Price in effect at the time of the
  record date for such dividend or of the effective date of such
<PAGE>

  subdivision, combination or reclassification, and the number and
  kind of shares of capital stock issuable on such date upon
  exercise of a Right, shall be proportionately adjusted so that
  the holder of any Right exercised after such time shall be
  entitled to receive, upon payment of the Purchase Price then in
  effect, 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 share 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 or Section 13
  hereof, the adjustment provided for in this Section 11(a)(i)
  shall be in addition to, and shall be made prior to, any
  adjustment required pursuant to Section 11(a)(ii) or Section 13
  hereof.

            (ii)  Subject to Section 24 and the last sentence of
  Section 23(b) of this Agreement, in the event that any Person, at
  any time after the date of this Agreement, shall become an
  Acquiring Person, each holder of a Right, except as provided
  below, shall thereafter have a right to receive, upon exercise
  thereof at a price equal to the then current Purchase Price
  multiplied by the number of shares of Common Stock for which a
  Right is then exercisable, in accordance with the terms of this
  Agreement, such number of shares of Common Stock of the Company
  as shall equal the result obtained by (x) multiplying the then
  current Purchase Price by the number of shares of Common Stock
  for which a Right is then exercisable and dividing that product
  by (y) 50% of the then current per share market price of the
  Company's Common Stock (determined pursuant to Section 11(d)
  hereof) on the date on which any Person shall become an Acquiring
  Person.  In the event that any Person shall become an Acquiring
  Person and the Rights shall then be outstanding, the Company
  shall not take any action which would eliminate or diminish the
  benefits intended to be afforded by the Rights.

       Notwithstanding the foregoing, any Rights that are or were
  acquired or beneficially owned by any Acquiring Person (or any
  Associate or Affiliate of such Acquiring Person) shall be null
  and void and any holder of such Rights shall thereafter have no
  right to exercise such Rights under any provision of this
  Agreement. No Right Certificate shall be issued pursuant to
  Section 3 that represents Rights beneficially owned by an
  Acquiring Person or any Associate or Affiliate thereof whose
  Rights would be void pursuant to the preceding sentence, and no
  Right Certificate shall be issued at any time upon the transfer
  of any Rights to an Acquiring Person or any Associate or
  Affiliate thereof or to any nominee of such Acquiring Person,
  Associate or Affiliate whose Rights would be null and void
  pursuant to the preceding sentence, and any Right Certificate
  delivered to the Rights Agent for transfer to an Acquiring Person
  or any Associate or Affiliate thereof whose Rights would be null
  and void pursuant to the preceding sentence shall be cancelled.
<PAGE>


            (iii)  In the event that the number of shares of Common
  Stock which is authorized by the Company's certificate of
  incorporation but not outstanding or reserved for issuance for
  purposes other than a upon exercise of the Rights is not
  sufficient to permit the exercise in full of the Rights in
  accordance with Section 11(a)(ii) and the Rights shall become so
  exercisable, the Company shall, within thirty days after the
  surrender of such Rights, and to the extent permitted by
  applicable law and any material agreements in effect on the date
  hereof to which the Company is a party:  (A) determine the value
  of the Common Stock issuable upon the exercise of each Right (the
  "Current Value") and (B) with respect to each Right, upon
  exercise of such Right, issue shares of Common Stock to the
  extent available for the exercise in full of such Right and, to
  the extent shares of Common Stock are not so available, make
  adequate provision to substitute for the Common Stock in question
  not received upon exercise of such Right (1) cash, (2) other
  equity securities of the Company (including, without limitation,
  shares, or units of shares, of preferred stock or preference
  stock which are deemed in good faith by the Board of Directors to
  have substantially the same value as shares of Common Stock (such
  other equity securities are herein called "common stock
  equivalents")), (3) debt securities of the Company, (4) other
  assets, or (5) any combination of the foregoing, having a value
  which, when added to the value of the shares of Common Stock
  actually issued upon exercise of such Right, shall have an
  aggregate value equal to the applicable Current Value, where such
  aggregate value has been determined in good faith by the Board of
  Directors based upon the advice of a nationally recognized
  independent investment banking firm selected in good faith by the
  Board of Directors.  If the Board of Directors shall determine in
  good faith that it is likely that sufficient additional shares of
  Common Stock could be authorized for issuance upon exercise in
  full of the Rights, the thirty day period set forth above may be
  extended to the extent necessary, but no more than ninety days
  after the event giving rise to the right to exercise the Rights
  in accordance with Section 11(a)(ii) (the "Section 11(a)(ii)
  Event"), in order that the Company may seek shareholder approval
  for the authorization of such additional shares (such thirty day
  period, as it may be extended, is herein called the "Common Stock
  Substitution Period").  To the extent that the Company determines
  that some action must be taken pursuant to the first and/or
  second sentence of this Section 11(a)(iii), the Company (x) shall
  provide, subject to Section 11(a)(ii) and the last sentence of
  this Section 11(a)(iii), that such action shall apply uniformly
  to all outstanding Rights (except to the extent provided by the
  second sentence of Section 11(a)(ii) hereof), and (y) may suspend
  the exercisability of the Rights until the expiration of the
  Common Stock Substitution Period in order to seek any
  authorization of additional shares and/or to decide the
  appropriate form of distribution to be made pursuant to such
  first sentence and to determine the value thereof.  In the event
  of any such suspension, the Company shall issue a public
  announcement stating that the exercisability of the Rights has
  been temporarily suspended, as well as a public announcement at
  such time as the suspension is no longer in effect.  For purposes
  of this Section 11(a)(iii), the value of a share of Common Stock
<PAGE>

  shall be the current per share market price of the Common Stock
  on the date of the Section 11(a)(ii) Event and the per share or
  per unit value of any common stock equivalent shall be deemed to
  equal the current per share market price of the Common Stock on
  such date.  The Board of Directors may, but shall not be required
  to, establish procedures to allocate the right to receive Common
  Stock upon the exercise of the Rights among holders of the Rights
  pursuant to this Section 11(a)(iii).

       (b)  In the event that the Company shall fix a record date
  for the issuance of rights, options or warrants to all holders of
  Common Stock entitling them (for a period expiring within 45
  calendar days after such record date) to subscribe for or
  purchase Common Stock (or shares having the same rights,
  privileges and preferences as the Common Stock ("equivalent
  common stock")) or securities convertible into Common Stock or
  equivalent common stock at a price per share of Common Stock or
  equivalent common stock (or having a conversion price per share,
  if a security convertible into Common Stock or equivalent common
  stock) less than the then current per share market price of the
  Common Stock (as defined in Section 11(d) on such record date),
  the Purchase Price to be in effect after such record date shall
  be determined by multiplying the Purchase Price in effect
  immediately prior to such record date by a fraction, the
  numerator of which shall be the number of shares of Common Stock
  outstanding on such record date plus the number of shares of
  Common Stock which the aggregate offering price of the total
  number of shares of Common Stock and/or equivalent common stock
  so to be offered (and/or the aggregate initial conversion price
  of the convertible securities so to be offered) would purchase at
  such current market price and the denominator of which shall be
  the number of shares of Common Stock outstanding on such record
  date plus the number of additional shares of Common Stock and/or
  equivalent common 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 the aggregate par value of the shares of
  capital stock of the Company issuable upon exercise of one Right. 
  In case such subscription price may be paid in a consideration
  part or all of which shall be in a form other than cash, the
  value of such consideration shall be as determined in good faith
  by the Board, whose determination shall be described in a
  statement filed with the Rights Agent and shall be conclusive for
  all purposes.  Common 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 Purchase Price
  shall be adjusted to be the Purchase Price which would then be in
  effect if such record dated had not been fixed.

       (c)  In the event that the Company shall fix a record date
  for the making of a distribution to all holders of the Common
  Stock (including any such distribution made in connection with a
  consolidation or merger in which the Company is the continuing or
  surviving corporation) of evidences of indebtedness, cash (other
  than a regular quarterly or other periodic cash dividend out of
<PAGE>

  the earnings or retained earnings of the Company), assets, stock
  (other than a dividend payable in Common Stock) or subscription
  rights, options or warrants (excluding those referred to in
  Section 11(b) hereof), the Purchase Price to be in effect after
  such record date shall be determined by multiplying the Purchase
  Price in effect immediately prior to such record date by a
  fraction, the numerator of which shall be the then current per
  share market price of the Common Stock on such record date, less
  the fair market value (as determined in good faith by the Board,
  whose determination shall be described in a statement filed with
  the Rights Agent and shall be conclusive for all purposes) of the
  portion of the cash, assets, stock or evidences of indebtedness
  so to be distributed or of such subscription rights or warrants
  applicable to one share of Common Stock, and the denominator of
  which shall be such current per share market price of the Common
  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 Purchase Price shall again be adjusted to be the
  Purchase Price which would then be in effect if such record date
  had not been fixed.

       (d)(i)    For the purpose of any computation hereunder, the
  "current per share market price" of any security (a "Security"
  for the purpose of this Section 11(d)(i)) on any date shall be
  deemed to be the average of the daily closing prices per share of
  such Security for the 30 consecutive Trading Days (as such term
  is hereinafter defined) immediately prior to such date; provided,
  however, that in the event that the current per share market
  price of the Security is determined during a period following the
  announcement by the issuer of such Security of (A) a dividend or
  distribution on such Security payable in shares of such Security
  or securities convertible into such shares, or (B) any
  subdivision, combination or reclassification of such Security,
  and prior to the expiration of 30 consecutive Trading Days after
  the ex-dividend date for such dividend or distribution, or the
  record date for such subdivision, combination or
  reclassification, then, and in each such case, the current per
  share market price shall be appropriately adjusted to reflect the
  current market price per share equivalent of such Security.  The
  closing price for each day shall be the last sale price, regular
  way, or, in case no such sale takes place on such day, the
  average of the closing bid and asked prices, regular way, in
  either case as reported in the principal consolidated transaction
  reporting system with respect to securities listed or admitted to
  trading on the New York Stock Exchange or, if the Security is not
  listed or admitted to trading on the New York Stock Exchange, as
  reported in the principal consolidated transaction reporting
  system with respect to securities listed on the principal
  national securities exchange on which the Security is listed or
  admitted to trading or, if the Security is not listed or admitted
  to trading on any national securities exchange, the last quoted
  price or, if not so quoted, the average of the high bid and low
  asked prices in the over-the-counter market, as reported by the
  National Association of Securities Dealers, Inc. Automated
<PAGE>

  Quotation System ("NASDAQ") or such other system then in use, or
  if on any date the Security is not quoted by any such
  organization, the average of the closing bid and asked prices as
  furnished by a professional market maker in the Security selected
  by the Board.  The term "Trading Day" shall mean a day on which
  the principal national securities exchange on which the Security
  is listed or admitted to trading is open for the transaction of
  business or, if the Security is not listed or admitted to trading
  on any national securities exchange, a Business Day.

            (ii) For the purpose of any computation hereunder, if
  the Common Stock is not or so listed or traded, "current per
  share market price" shall mean the fair value per share as
  determined in good faith by the Board, whose determination shall
  be described in a statement filed with the Rights Agent and shall
  be conclusive for all purposes.

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

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

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

       (h)  Unless the Company shall have exercised its election as
  provided in Section 11(i), upon each adjustment of the Purchase
  Price as a result of the calculations made in Sections 11(b) and
  (c), each Right outstanding immediately prior to the making of
  such adjustment shall thereafter evidence the right to purchase,
  at the adjusted Purchase Price, that number of shares of Common
  Stock (calculated to the nearest one ten-thousandth of a share of
<PAGE>

  Common Stock) obtained by (i) multiplying (x) the number of
  shares of Common Stock covered by a Right immediately prior to
  this adjustment by (y) the Purchase Price in effect immediately
  prior to such adjustment of the Purchase Price and (ii) dividing
  the product so obtained by the Purchase Price in effect
  immediately after such adjustment of the Purchase Price.

       (i)  The Company may elect on or after the date of any
  adjustment of the Purchase Price to adjust the number of Rights,
  in substitution for any adjustment in the number of shares of
  Common 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 shares of Common
  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 Purchase Price in effect immediately prior to
  adjustment of the Purchase Price by the Purchase Price in effect
  immediately after adjustment of the Purchase Price.  The Company
  shall make a public announcement of its election to adjust the
  number of Rights, indicating the record date for the adjustment,
  and, if known at the time, the amount of the adjustment to be
  made.  This record date may be the date on which the Purchase
  Price is adjusted or any day thereafter, but, if the Right
  Certificates have been issued, shall be at least 10 days later
  than the date of the public announcement.  If Right Certificates
  have been issued, upon each adjustment of the number of Rights
  pursuant to this Section 11(i), the Company shall, as promptly as
  practicable, cause to be distributed to holders of record of
  Right Certificates on such record date Right Certificates
  evidencing, subject to Section 14 hereof, the additional Rights
  to which such holders shall be entitled as a result of such
  adjustment, or, at the option of the Company, shall cause to be
  distributed to such holders of record in substitution and
  replacement for the Right Certificates held by such holders prior
  to the date of adjustment, and upon surrender thereof, if
  required by the Company, new Right Certificates evidencing all
  the Rights to which such holders shall be entitled after such
  adjustment.  Right Certificates so to be distributed shall be
  issued, executed and countersigned in the manner provided for
  herein and shall be registered in the names of the holders of
  record of Right Certificates on the record date specified in the
  public announcement.

       (j)  Irrespective of any adjustment or change in the
  Purchase Price or the number of shares of Common Stock issuable
  upon the exercise of the Rights, the Right Certificates
  theretofore and thereafter issued may continue to express the
  Purchase Price and the number of shares of Common Stock which
  were expressed in the initial Right Certificates issued
  hereunder.

       (k)  Before taking any action that would cause an adjustment
  reducing the Purchase Price below the then par value, if any, of
  the shares of Common Stock issuable upon exercise of the Rights,
  the Company shall take any corporate action which may, in the
  opinion of its counsel, be necessary in order that the Company
<PAGE>

  may validly and legally issue fully paid and nonassessable shares
  of Common Stock at such adjusted Purchase Price.

       (l)  In any case in which this Section 11 shall require that
  an adjustment in the Purchase Price be made effective as of a
  record date for a specified event, the Company may elect to defer
  until the occurrence of such event the issuing to the holder of
  any Right exercised after such record date of the Common Stock
  and other capital stock or securities of the Company, if any,
  issuable upon such exercise over and above the Common Stock and
  other capital stock or securities of the Company, if any,
  issuable upon such exercise on the basis of the Purchase Price in
  effect prior to such adjustment; provided, however, that the
  Company shall deliver to such holder a due bill or other
  appropriate instrument evidencing such holder's right to receive
  such additional shares upon the occurrence of the event requiring
  such adjustment.

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

       (n)  Notwithstanding anything in this Agreement to the
  contrary, 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 otherwise
  than by payment of dividends in shares of Common Stock into a
  greater or lesser number of shares of Common Stock, then in any
  such case (i) the number of shares of Common Stock purchasable
  after such event upon proper exercise of each Right shall be
  determined by multiplying the number of shares of Common 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 (ii) 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(n) shall be made successively whenever such a dividend is
  declared or paid or such a subdivision, combination or
  consolidation is effected.

       Section 12.  Certificate of Adjusted Purchase Price or
<PAGE>

  Number of Shares.  Whenever an adjustment is made as provided in
  Sections 11 and 13 hereof, the Company shall promptly (a) prepare
  a certificate setting forth such adjustment and a brief statement
  of the facts accounting for such adjustment, (b) file with the
  Rights Agent and with each transfer agent for the Common Stock a
  copy of such certificate, and (c) mail a brief summary thereof to
  each holder of a Right Certificate in accordance with Section 26
  hereof.  The Rights Agent may rely on such certificate and shall
  not be deemed to have knowledge of any such adjustment unless and
  until it shall have received such certificate.

       Section 13.  Consolidation, Merger or Sale or Transfer of
  Assets or Earnings Power.  (a)  In the event that, following the
  Distribution Date, directly or indirectly, (i) the Company shall
  consolidate with, or merge with and into, any other Person and
  the Company shall not be the continuing or surviving corporation
  of such consolidation or merger, (ii) any Person shall
  consolidate with the Company, or merge with and into the Company
  and the Company shall be the continuing or surviving corporation
  of such merger or consolidation and, in connection with such
  merger or consolidation, all or part of the Common Stock shall be
  changed into or exchanged for stock or other securities of any
  other Person (or the Company) or cash or any other property, or
  (iii) the Company shall sell or otherwise transfer (or one or
  more of its Subsidiaries shall sell or otherwise transfer), in
  one or more transactions, assets or earning power aggregating 50%
  or more of the assets or earning power of the Company and its
  Subsidiaries (taken as a whole) to any Person other than the
  Company or one or more of its wholly-owned Subsidiaries, then,
  and in each such case, proper provision shall be made so that (i)
  each holder of a Right (except as otherwise provided herein)
  shall thereafter have the right to receive, upon the exercise
  thereof at a price equal to the then current Purchase Price
  multiplied by the number of shares of Common Stock for which a
  Right is then exercisable, in accordance with the terms of this
  Agreement and in lieu of Common Stock, such number of shares of
  validly authorized and issued, fully paid, nonassessable and
  freely tradeable Common Stock of the Issuer (as such term is
  defined in Section 13(b) hereof), free and clear of any liens,
  encumbrances and other adverse claims and not subject to any
  rights of call or first refusal, as shall equal the result
  obtained by (X) multiplying the then current Purchase Price by
  the number of shares of Common Stock for which a Right is then
  exercisable and dividing that product by (Y) 50% of the then
  current per share market price of the Common Stock (determined
  pursuant to Section 11(d) hereof) of the Issuer on the date of
  consummation of such consolidation, merger, sale or transfer;
  (ii) the Issuer of such Common Stock shall thereafter be liable
  for, and shall assume, by virtue of such consolidation, merger,
  sale or transfer, all the obligations and duties of the Company
  pursuant to this Agreement; (iii) the term "Company" shall
  thereafter be deemed to refer to the Issuer; and (iv) the Issuer
  shall take such steps (including, but not limited to, the
  reservation of a sufficient number of shares of its Common Stock
  to permit the exercise in full of all outstanding Rights which
  have not become null and void in accordance with Section
  11(a)(ii)) in connection with such consummation as may be
  necessary to assure that the provisions hereof shall thereafter
<PAGE>

  be applicable, as nearly as reasonably may be, in relation to the
  Common Stock thereafter deliverable upon the exercise of the
  Rights.  The Company shall not consummate any such consolidation,
  merger, sale or transfer described in this Section 13(a) unless
  prior thereto the Company and such Issuer shall have executed and
  delivered to the Rights Agent a supplemental agreement so
  providing.  The Company shall not enter into any transaction of
  the kind referred to in this Section 13(a) if at the time of such
  transaction there are any rights, warrants, instruments or
  securities outstanding or any agreements or arrangements which,
  as a result of the consummation of such transaction, would
  eliminate or substantially diminish the benefits intended to be
  afforded by the Rights.

       (b)  For purposes of this Section 13, "Issuer" shall mean
  (i) in the case of any event described in Sections 13(a)(i) or
  (ii) above, the Person that is the continuing, surviving,
  resulting or acquiring Person (including the Company as the
  continuing or surviving corporation of a transaction described in
  Section 13(a)(ii) above), and (ii) in the case of any event
  described in Section 13(a)(iii) above, the Person that is the
  party receiving the greatest portion of the assets or earning
  power (including without limitation securities creating any
  obligation on the part of the Company and/or any of its
  Subsidiaries) transferred pursuant to such transaction or
  transactions; provided, however, that, in any such case, (A) if
  (1) no class of equity security of such Person is, at the time of
  such merger, consolidation or transaction and has been
  continuously over the preceding 12-month period, registered
  pursuant to Section 12 of the Exchange Act, and (2) such Person
  is a Subsidiary, directly or indirectly, of another Person, a
  class of equity security of which is and has been so registered,
  the term "Issuer" shall mean such other Person; and (B) in case
  such Person is a Subsidiary, directly or indirectly, of more than
  one Person, a class of equity security of two or more of which
  are and have been so registered, the term "Issuer" shall mean
  whichever of such Persons is the issuer of the class of equity
  security having the greatest aggregate market value.

       Notwithstanding the foregoing, if the Issuer in any of the
  events described in Section 13(a) is not a corporation or other
  legal entity having outstanding equity securities, then, and in
  each such case, (i) if the Issuer is directly or indirectly
  wholly owned by a corporation or other legal entity having
  outstanding equity securities, then all references to Common
  Stock of the Issuer shall be deemed to be references to the
  Common Stock of the corporation or other legal entity having
  outstanding equity securities which ultimately controls the
  Issuer, and (ii) if there is no such corporation or other legal
  entity having outstanding equity securities, (Y) proper provision
  shall be made so that the Issuer shall create or otherwise make
  available for purposes of the exercise of the Rights in
  accordance with the terms of this Agreement, a type or types of
  security or securities having a fair market value at least equal
  to the economic value of the Common Stock which each holder of a
  Right would have been entitled to receive if the Issuer had been
  a corporation or other legal entity having outstanding equity
  securities and (Z) all other provisions of this Agreement shall
<PAGE>

  apply to the issuer of such securities as if such securities were
  Common Stock.

       (c)  The Company shall not consummate any consolidation,
  merger, sale or transfer described in Section 13(a) unless the
  Issuer shall have a sufficient number of authorized shares of
  Common Stock (or other securities as contemplated in Section
  13(b) above) which have not been issued or reserved for issuance
  to permit the exercise in full of the Rights in accordance with
  this Section 13 and unless prior to such consummation the Company
  and the Issuer shall have executed and delivered to the Rights
  Agent a supplemental agreement providing for the terms set forth
  in subsections (a) and (b) of this Section 13 and further
  providing that as soon as practicable after the consummation of
  any such consolidation, merger, sale or transfer described in
  Section 13(a), the Issuer will (i), if legally required, prepare
  and file a registration statement under the Securities Act, with
  respect to the Rights and the securities purchasable upon
  exercise of the Rights on an appropriate form, and will use its
  best efforts to cause such registration statement to (A) become
  effective as soon as practicable after such filing and (B) remain
  effective (with a prospectus at all times meeting the
  requirements of the Securities Act) until the Expiration Date;
  (ii), if legally required, take all such actions 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; and (iii) deliver to holders of the
  Rights historical financial statements for the Issuer and each of
  its Affiliates which comply in all respects with the requirements
  for registration on Form 10 under the Exchange Act.

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

       Section 14.    Fractional Rights and Fractional Shares.  (a)
  The Company shall not be required to issue fractions of Rights or
  to distribute Right Certificates which evidence fractional
  Rights.  In lieu of such fractional Rights, there shall be paid
  to the registered holders of the Right Certificates with regard
  to which such fractional Rights would otherwise be issuable, an
  amount in cash equal to the same fraction of the current market
  value of a whole Right.  For the purposes of this Section 14(a),
  the current market value of a whole Right shall be the closing
  price per Right for the Trading Day immediately prior to the date
  on which such fractional Rights would have been otherwise
  issuable.  The closing price for any day shall be the last sale
  price, regular way, or, in case no such sale takes place on such
  day, the average of the closing bid and asked prices, regular
  way, in either case as reported in the principal consolidated
  transaction reporting system with respect to securities listed or
  admitted to trading on the New York Stock Exchange, or if the
  Rights are not listed or admitted to trading on the New York
  Stock Exchange, as reported in the principal consolidated
  transaction reporting system with respect to securities listed on
  the principal national securities exchange on which the Rights
  are listed or admitted to trading or, if the Rights are not
  listed or admitted to trading on any national securities
<PAGE>

  exchange, the last quoted price or, if not so quoted, the average
  of the high bid and low asked prices in the over-the-counter
  market, as reported by NASDAQ or such other system then in use
  or, if on any such date the Rights are not quoted by any such
  organization, the average of the closing bid and asked prices as
  furnished by a professional market maker making a market in the
  Rights selected by the Board.  If on any such date no such market
  maker is making a market in the Rights, the fair value of the
  Rights on such date as determined in good faith by the Board
  shall be used and such determination, which shall be described in
  a statement filed with the Rights Agent, shall be conclusive for
  all purposes.

       (b)  The Company shall not be required to issue fractions of
  shares of Common Stock upon exercise of the Rights or to
  distribute certificates which evidence fractional shares of
  Common Stock.  In lieu of fractional shares of Common Stock, the
  Company shall pay to the registered holders of Right Certificates
  at the time such Rights are exercised as herein provided with
  regard to which such fractional shares would otherwise be
  issuable, an amount in cash equal to the same fraction of the
  current market value of a whole share of Common Stock.  For the
  purposes of this Section 14(b), the current market value of a
  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 such exercise.

       (c)  The holder of a Right by the acceptance of the Rights
  expressly waives the right to receive any fractional Rights or
  any fractional shares of Common Stock upon exercise of a Right.  

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

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

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

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

            (c)  the Company and the Rights Agent may deem and
  treat the person in whose name the Right Certificate (or, prior
  to the Distribution Date, the associated Common Stock
  certificate) is registered as the absolute owner thereof and of
  the Rights evidenced thereby (notwithstanding any notations of
  ownership or writing on the Right Certificates or the associated
  Common 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.  

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

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

       The Rights Agent shall be protected and shall incur no
  liability for, or in respect of any action taken, suffered or
  omitted by it in connection with, its administration of this 
  Agreement in reliance upon any Right Certificate or certificate
<PAGE>

  for the Common Stock or for other securities of the Company,
  instrument of assignment or transfer, power of attorney,
  endorsement, affidavit, letter, notice, discretion, consent,
  certificate, statement or other paper or document believed by it
  to be genuine and to be signed, executed and, where necessary,
  verified or acknowledged, by the proper person or persons, or
  otherwise upon the advice of counsel as set forth in Section 20
  hereof.  

       Section 19.  Merger or Consolidation or Change of Name of
  Rights Agent.  Any corporation into which the Rights Agent or any
  successor Rights Agent may be merged or with which it may be
  consolidated, or any corporation resulting from any merger or
  consolidation to which the Rights Agent or any successor Rights
  Agent shall be a party, or any corporation succeeding to the
  stock transfer or corporate trust business of the Rights Agent or
  any successor Rights Agent, shall be successor to the Right Agent
  under this Agreement without the execution or filing of any paper
  or any further action the part of any of the parties hereto,
  provided that such corporation would be eligible for appointment
  as a successor Rights Agent under the provisions of Section 21
  hereof.  In case at the time such successor Rights Agent shall
  succeed to the agency created by this Agreement any of the Right
  Certificates shall have been countersigned but not delivered, any
  such successor Rights Agent may adopt the countersignature of the
  predecessor Rights Agent and deliver such Rights Certificates so
  countersigned; and in case at that time any of the Right
  Certificates shall not have been countersigned, any successor
  Rights Agent may countersign such Right Certificates either in
  the name of the predecessor Rights Agent or in the name of the
  successor Rights Agent; and in all such cases such Right
  Certificates shall have the full force and effect provided in the
  Right Certificates and in this Agreement.  

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

       Section 20.  Duties of Rights Agent.  The Rights Agent
  undertakes the duties and obligations imposed by this Agreement
  upon the following terms and conditions, by all of which the
  Company and the holders of Right Certificates, by their
  acceptance thereof, shall be bound:  

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

            (b)  Whenever in the performance of its duties under
<PAGE>

  this 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
  President, any Vice President, the Treasurer or the Secretary of
  the Company and delivered to the Rights Agent; and such
  certificate shall be full authorization to the Rights Agent for
  any action taken or suffered in good faith by it under the
  provisions of this Agreement in reliance upon such certificate.  

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

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

            (e)  The Rights Agent shall not be under any
  responsibility in respect of the validity of this Agreement or
  the execution and delivery hereof (except the due execution
  hereof by the Rights Agent) or in respect of the validity or
  execution of any Right Certificate (except its countersignature
  thereof); nor shall it be responsible for any breach by the
  Company of any covenant or condition contained in this Agreement
  or in any Right Certificate; nor shall it be responsible for any
  change in the exercisability of the Rights (including the Rights
  becoming void pursuant to Section 11(a)(ii) hereof) or any
  adjustment in the terms of the Rights (including the manner,
  method or amount thereof) provided for in Sections 11, 13, 23, or
  24, or the ascertaining of the existence of facts that should
  requires any such change or adjustment (except with respect to
  the exercise of Rights evidenced by Right Certificates after
  receipt of a certificate furnished pursuant to Section 12,
  describing such change or adjustment); nor shall it by any act
  hereunder be deemed to make any representation or warranty as to
  the authorization or reservation of any shares of Common Stock to
  be issued pursuant to this Agreement or any Right Certificate or
  as to whether any shares of Common Stock will, when issued, be
  validly authorized and issued, fully paid and nonassessable.

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

            (g)  The Rights Agent is hereby authorized and directed
  to accept instructions with respect to the performance of its
  duties hereunder from any one of the Chairman of the Board, the
  President, any Vice President, the Treasurer or the Secretary of
  the Company, and to apply to such officers for advice or
<PAGE>

  instructions in connection with its duties, and it shall not be
  liable for any action taken or suffered by it in good faith in
  accordance with instructions of any such officer or for any delay
  in acting while waiting for those instructions.  

       Any application by the Rights Agent for written instructions
  from the Company may, at the option of the Rights Agent, set
  forth in writing any action proposed to be taken or omitted by
  the Rights Agent under this Rights Agreement and the date on
  and/or after which such action shall be taken or such omission
  shall be effective.  The Rights Agent shall not be liable for any
  action taken by, or omission of, the Rights Agent in accordance
  with a proposal included in any such application on or after the
  date specified in such application (which date shall not be less
  than five Business Days after the date any officer of the Company
  actually receives such application, unless any such officer shall
  have consented in writing to an earlier date) unless, prior to
  taking any such action (or the effective date in the case of an
  omission), the Rights Agent shall have received written
  instructions in response to such application specifying the
  action to be taken or omitted.

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

            (i)  The Rights Agent may execute and exercise any of
  the rights or powers hereby vested in it or perform any duty
  hereunder either itself or by or through its attorneys or agents,
  and the Rights Agent shall not be answerable or accountable for
  any act, default, neglect or misconduct of any such attorneys or
  agents or for any loss to the company resulting from any such
  act, default, neglect or misconduct, provided reasonable care was
  exercised in the selection and continued employment thereof.  The
  Rights Agent shall not be under any duty or responsibility to
  insure compliance with any applicable federal or state securities
  laws in connection with the issuance, transfer or exchange or
  Right Certificates.  

       Section 21.  Change of Rights Agent.  The Rights Agent or
  any successor Rights Agent may resign and be discharged from its
  duties under this Agreement upon 30 days' notice in writing
  mailed to the Company and to each transfer agent of the Common
  Stock by registered or certified mail, and to the holders of the
  Right Certificates by first-class mail.  The Company may remove
  the Rights Agents or any successor Rights Agent upon 30 days'
  notice in writing, mailed to the Rights Agent or successor Rights
  Agent, as the case may be, and to each transfer agent of the
  Common Stock by registered or certified mail, and to the holders
  of the Right Certificates by first-class mail.  If the Rights 
  Agent shall resign or be removed or shall otherwise become
  incapable of acting, the Company shall appoint a successor to the
<PAGE>

  Rights Agent.  If the Company shall fail to make such appointment
  within a period of 30 days after giving notice of such removal or
  after it has been notified in writing of such resignation or
  incapacity by the resigning or incapacitated Rights Agent or by
  the holder of a Right Certificate (who shall, with such notice,
  submit his Right Certificate for inspection by the Company), then
  the registered holder of any Right Certificate may apply to any
  court of competent jurisdiction for the appointment of a new
  Rights Agent.  Any successor Rights Agent, whether appointed by
  the Company or by such a court, shall be a corporation organized
  and doing business under the laws of the United States or of any
  other state of the United States, in good standing, which is
  authorized under such laws to exercise corporate trust or stock
  transfer powers and is subject to supervision or examination by
  federal or state authority and which has at the time of its
  appointment as Rights Agent a combined capital and surplus of at
  least $50 million.  After appointment, the successors 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 of the delivery and transfer of such property. 
  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
  mail a notice thereof in writing to the holders of the Right
  Certificates.  Failure to give any notice provided for in this
  Section 21, however, or any defect therein, shall not affect the
  legality or validity of the resignation or removal of the Rights
  Agent or the appointment of the successor Rights Agent, as the
  case may be.  

       Section 22.  Issuance of New Right Certificates. 
  Notwithstanding any of the provisions of this Agreement or of the
  Rights to the contrary, the Company may, at its option, issue new
  Right Certificates evidencing Rights in such form as may be
  proved by the Board to reflect any adjustment or change in the
  Purchase Price and the number of kind or class of shares or other
  securities or property purchasable under the Right Certificates
  made in accordance with the provisions of this Agreement.  

       Section 23.   Redemption.  (a) The Rights may be redeemed by
  action of the Board pursuant to paragraph (b) of this Section 23
  and shall not be redeemed in any other manner.  

       (b)  The Board may, at its option, and as provided herein,
  at any time prior to the earlier of (i) the Close of Business on
  the fourteenth day following the Stock Acquisition Date, subject
  to extension by the Board as provided in Section 23(c) hereof, or
  (ii) the Close of Business on the Final Expiration Date, upon the
  concurrence of Directors holding a majority of the Directorships
  on the Board, redeem all (but not less than all) of the then
  outstanding Rights at a redemption price of $.005 per Right,
  appropriately adjusted to reflect any stock split, stock divided,
  combination of shares or similar transaction occurring after the
  date hereof (such redemption price being hereinafter referred to
<PAGE>

  as the "Redemption Price"); provided, however, if the Board so
  authorizes redemption of the Rights after a Stock Acquisition
  Date, then there must be Continuing Directors then in office and
  such authorization shall require the concurrence of a majority of
  such Continuing Directors.  The redemption of the Rights by the
  Board may be made effective at such time, on such basis and with
  such conditions as the Board in its sole discretion may
  establish.  Notwithstanding anything contained in this Agreement
  to the contrary, the Rights shall not be exercisable after the
  first occurrence of an event described in Section 11(a)(ii) until
  such time as the Company's right of redemption hereunder has
  expired.

       (c)  The Board may, at its option and as provided herein, at
  any time prior to the Close of Business on the Final Expiration
  Date and prior to such time as the Rights are no longer
  redeemable by the Board, from time to time supplement or amend
  the Rights Agreement without approval of the holders of any
  Rights or the Rights Agent, to extend or shorten the period
  during which the Rights may be redeemed; provided, however, that
  after a Stock Acquisition Date, if the Board authorizes any such
  amendment or supplement extending or shortening the period during
  which the Rights may be redeemed, then there must be Continuing
  Directors then in office and such authorization shall require the
  concurrence of a majority of such Continuing Directors.  

       (d)  Immediately upon the action of the Board ordering the
  redemption of the Rights pursuant to paragraph (b) of this
  Section 23, and without any further action and without any
  notice, the right to exercise the Rights will terminate and the
  only right thereafter of the holders of Rights shall be to
  receive the Redemption Price.  The Company shall promptly give
  public notice of any such redemption; provided, however, that the
  failure to give, or any defect in, any such notice shall not
  affect the validity of such redemption.  Within 10 days after
  such action of the Board ordering the redemption of the Rights
  pursuant to paragraph (b), as the case may be, the Company shall
  mail a notice of redemption to all the holders of the then
  outstanding Rights at their last addresses as they appear upon
  the registry books of the Rights Agent or, prior to the
  Distribution Date, on the registry books of the transfer agent
  for the Common Stock.  Any notice which is mailed in the manner
  herein provided shall be deemed given, whether or not the holder
  receives the notice.  Each such notice of redemption will state
  the method by which the payment of the Redemption Price will be
  made.  Neither the Company nor any of is Affiliates or Associates
  may redeem, acquire or purchase for value any Rights at any time
  in any manner other than that specifically set forth in this
  Section 23 or in Section 24 hereof, and other than in connection
  with the purchase of shares or Common Stock prior to the
  Distribution Date.  

       Section 24.  Exchange.  (a)  The Board 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 that have become void
  pursuant to the provisions of Section 11(a)(ii) hereof) for
  Common Stock at an exchange ratio of one share of Common Stock
<PAGE>

  per Right, appropriately adjusted to reflect any stock split,
  stock dividend or similar transaction occurring after the date
  hereof (such exchange ratio being hereinafter referred to as the
  "Exchange Ratio").  Common Stock issued pursuant to this Section
  24(a) shall be duly and validly authorized and issued, fully
  paid, nonassessable and fully tradeable shares, free and clear of
  any liens, encumbrances and other adverse claims and not subject
  to any rights of call or first refusal.  Notwithstanding the
  foregoing, the Board shall not be empowered to effect such
  exchange at any time after any Person (other than the Company or
  any Related Person), together with all Affiliates and Associates
  of such Persons, becomes the Beneficial Owner of 50% or more of
  the shares of Common Stock then outstanding.  

       (b)  Immediately upon the action of the Board ordering the
  exchange of any Rights pursuant to subsection (a) of this Section
  24 and without any further action and without any notice, the
  right to exercise such Rights shall terminate and the only right
  thereafter of a holder of such Rights shall be to receive that
  number of 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 public notice of any such exchange;
  provided, however, that the failure to give, or any defect in,
  such notice shall not affect the validity of such exchange.  The
  Company promptly shall mail a notice of any such exchange to all
  of the holders of such Rights at their last addresses as they
  appear upon the registry books of the Rights Agent.  Any notice
  which is mailed in the manner herein provided shall be deemed
  given, whether or not the holder receives the notice.  Each such
  notice of exchange will state the method by which the exchange of
  the Common Stock for Rights will be effected and, in the event of
  any partial exchange, the number of Right which will be
  exchanged.  Any partial exchange shall be effected pro rata based
  on the number of Rights (other than Rights which have become void
  pursuant to the provisions  of Section 11(a)(ii) hereof) held by
  each holder of Rights.  

       (c)  In the event that there shall not be sufficient Common
  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 take all such action as may be
  necessary to authorize additional shares of Common Stock for
  issuance upon exchange of the Rights.  

       (d)  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
  fractional shares of Common Stock, the Company shall pay to the
  registered holders of the Right Certificates with regard to which
  such fractional shares would otherwise be issuable, an amount in
  cash equal to the same fraction of the current market value of a
  whole share of Common Stock.  For the purposes of this paragraph
  (d), the current 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.  
<PAGE>

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

       In case any of the events set forth in Section 11(a)(ii) or
  Section 13 hereof shall occur, then the Company shall as soon as
  practicable thereafter give to each holder of a Right
  Certificate, in accordance with Section 26 hereof, a notice of
  the occurrence of such event, which notice shall describe such
  event and the consequences of such event to holders of Rights
  under Section 11(a)(ii) or Section 13 hereof.  

       Section 26.   Notices.  Notices or demands authorized by
  this Agreement to be given or made by the Rights Agent or by the
  holder of any Right Certificate to or on the Company shall be

       Section 27.  Supplements and Amendments.  (a) Prior to the
  Distribution Date and subject to Section 23(c) and Section 27(d)
  hereof, if the Company so directs, the Company and the Rights
  Agent shall supplement or amend any provision of this Agreement
  in any manner which the Company may deem desirable without the
  approval of any holders of Right Certificates or certificates
  representing shares of Common Stock.

       (b)  From and after the Distribution Date and subject to
  Section 23(c) and Section 27(d) hereof, if the Company so
  directs, the Company and the Rights Agent shall supplement or
  amend this Agreement without the approval of any holders of Right
  Certificates or certificates representing shares of Common Stock
  in order to cure any ambiguity, to correct or supplement any
  provision contained herein which may be defective or inconsistent
  with any other provisions herein, to shorten or lengthen any time
  period hereunder, or to supplement or amend the provisions of
  this Agreement in any manner which the Company may deem necessary
  or desirable, including, without limitation, the addition of
  other events requiring adjustment to the Rights under Sections 11
  or 13 or procedures relating to the redemption of the Rights,
  which supplement or amendment shall not, in the good faith
  determination of the Board, adversely affect the interests of the
  holders of Rights Certificates other than the Acquiring Person or
  any Affiliate or Associate of the Acquiring Person; provided,
  however, that there must be Continuing Directors then in office
  and such authorization shall require the concurrence of a
  majority of such Continuing Directors and a majority of the Board
  and, provided further, this Agreement may not be supplemented or
  amended to lengthen, pursuant to the preceding parts of this
  sentence, a time period relating to when the Rights may be
  redeemed at such time as the Rights are not then redeemable, or
  any other time period unless such lengthening is for the purpose
  of protecting, enhancing or clarifying the rights of, and/or the
  benefits to, the holders of Rights.

       (c)  Upon the delivery of a certificate from an officer of
<PAGE>

  the Company which states that the proposed supplement or
  amendment is in compliance with the terms of this Section 27, the
  Rights Agent shall execute such supplement or amendment;
  provided, however, that the failure or refusal of the Rights
  Agent to execute such supplement or amendment shall not affect
  the validity or effective date of any supplement or amendment
  adopted by the Company.

       (d)  Without limiting the foregoing, the Company may at any
  time prior to such time as any Person becomes an Acquiring Person
  amend this Agreement to lower the thresholds set forth in Section
  1(a) hereof from 15% to not less than the greater of (i) any
  percentage greater than the largest percentage of the outstanding
  shares of Common Stock then known by the Company to be
  beneficially owned by any Person (other than the Company or any
  Related Person) and (ii) 10%.  Notwithstanding anything in this
  Agreement to the Contrary, (i) no supplement or amendment shall
  be made which decreases the stated Redemption Price or the period
  of time remaining until the Final Expiration Date and (ii) the
  Rights Agent's consent must be obtained regarding any supplement
  or amendment pursuant to this Section which alters the Rights
  Agent's rights or duties, which consent shall not be unreasonably
  withheld.  

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

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

       Section 30.  Severability.  If any term, provision, covenant
  or restriction of this Agreement is held by a court of competent
  jurisdiction or other authority to be invalid, void or
  unenforceable, the remainder of the terms, provisions, covenants
  and restrictions of this Agreement shall remain in full force and
  effect and shall in no way be affected, impaired or invalidated. 
   
       Section 31.  Governing Law.  This Agreement and each Right

                        ImmuCell Corporation


       This certifies that __________________, or registered
  assigns, is the registered owner of the number of Rights set
  forth above, each of which entitles the owner thereof, subject to
  the terms, provisions and conditions of the Rights Agreement,
  dated as of September 5, 1995 (the "Rights Agreement"), between
  ImmuCell Corporation, a Delaware corporation (the "Company"), and
  American Stock Transfer & Trust Co. (the "Rights Agent"), to
  purchase from the Company at any time after the Distribution Date
  (as such term is defined in the Rights Agreement) and prior to
  5:00 P.M., Eastern time, on September 19, 2005 at the office of
  the Rights Agent designated for such purpose, or at the office of
  its successor as Rights Agent, one fully paid non-assessable
  share of Common Stock of the Company, at a purchase price of
  $70.00 per share (the "Purchase Price"), upon presentation and

  Purchase duly executed.  The number of Rights evidenced by this
  Right Certificate (and the number of shares of Common Stock which
  may be purchased upon exercise hereof) set forth above, and the
  Purchase Price set forth above, are the number and the Purchase
  Price as of September 19, 1995, based on the Common Stock as

       As provided in the Rights Agreement, the Purchase Price and
  the number and kind of securities which may be purchased upon the
<PAGE>

  exercise of the Rights evidenced by this Right Certificate are
  subject to modification and adjustment upon the happening of
  certain events, and the Rights are subject to amendment,
  redemption and certain other events.

       This Right Certificate is subject to all of the terms,
  provisions and conditions of the Rights Agreement, which terms,
  provisions and conditions are hereby incorporated herein by
  reference and made a part hereof and to which Rights Agreement
  reference is hereby made for a full description of the rights,
  limitations of rights, obligations, duties and immunities
  hereunder of the Rights Agent, the Company and the holders of the
  Right Certificates.  Copies of the Rights Agreement are on file
  at the principal executive offices of the Company and the above-
  mentioned offices of the Rights Agent.

       Pursuant to the Rights Agreement, if any Person shall become
  an Acquiring Person, (i) any Rights that are or were acquired or
  beneficially owned by any Acquiring Person (or any Associate or
  Affiliate of such Acquiring Person) shall be null and void and
  any holder of such Rights shall thereafter have no right to
  exercise such Rights under any provision of the Rights Agreement,
  (ii) no Right Certificate shall be issued pursuant to the Rights
  Agreement that represents Rights beneficially owned by an
  Acquiring Person or any Associate or Affiliate thereof, (iii) no
  Right Certificate shall be issued at any time upon the transfer
  of any Rights to an Acquiring Person or any Associate or
  Affiliate thereof or to any nominee of such Acquiring Person,
  Associate or Affiliate, and (iv) any Right Certificate delivered
  to the Rights Agent for transfer to an Acquiring Person or any
  Associate or Affiliate thereof shall be cancelled.

       This Right Certificate, with or without other Right
  Certificates, upon surrender at the principal office of the
  Rights Agent, may be exchanged for another Right Certificate or
  Right Certificates of like tenor and date evidencing Rights
  entitling the holder to purchase a like aggregate number of
  shares of Common Stock as the Rights evidenced by the Right
  Certificate or Right Certificates surrendered shall have entitled
  such holder to purchase.  If this Right Certificate shall be
  exercised in part, the holder shall be entitled to receive upon
  surrender hereof another Right Certificate or Right Certificates
  for the number of whole Rights not exercised.

       Subject to the provisions of the Rights Agreement, the
  Rights evidenced by this Certificate (i) may be redeemed by the
  Company at its option at a redemption price of $.005 per Right or
  (ii) may be exchanged in whole or in part for shares of Common
  Stock.

       No fractional shares of Common Stock will be issued upon the
  exercise of any Right or Rights evidenced hereby but in lieu of
  issuing fractional shares of Common Stock the Company may make a
  cash payment, as provided in the Rights Agreement.

       No holder of this Right Certificate, as such, shall be
  entitled to vote or receive dividends or be deemed for any
  purpose the holder of the Common Stock or of any other securities
<PAGE>

  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 any meeting hereof, 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
  Right Certificate shall have been exercised as provided in the
  Rights Agreement.

       This Right Certificate shall not be valid or obligatory for
  any purpose until it shall have been countersigned by the Rights
  Agent.

                                 B-1

                                
                                                          Exhibit B


                    SUMMARY OF RIGHTS TO PURCHASE
                            COMMON STOCK


       On September 5, 1995, the Board of Directors of ImmuCell
  Corporation (the "Company") declared a dividend of one common
  share purchase right (a "Right") for each of the then outstanding
  shares of Common Stock, par value $0.10 per share, (the "Common
  Stock") of the Company.  The dividend is payable on September 19,
  1995 (the "Record Date") to the stockholders of record on that
  date.  Each Right entitles the registered holder to purchase from
  the Company one share of Common Stock of the Company at a price
  of $70.00 per share (the "Purchase Price"), subject to
  adjustment.  The description and terms of the Rights are set
  forth in a Rights Agreement (the "Rights Agreement") between the
  Company and American Stock Transfer & Trust Co., as Rights Agent
  (the "Rights Agent").

       Until the earlier to occur of (i) 10 days following a public
  announcement that, without the prior consent of the "Continuing
  Directors" (as such term is defined in the Rights Agreement), a
  person or group of affiliated or associated persons has acquired
  beneficial ownership of 15% or more of the outstanding shares of
  Common Stock (such person being referred to as the "Acquiring
  Person"), or (ii) 10 days (or such later date as may be
  determined by action of the Board of Directors prior to such time
  as any Person becomes an Acquiring Person) following the
  commencement of, or announcement of an intention to make, a
  tender offer or exchange offer the consummation of which would
  result in the beneficial ownership by a person or group of 20% or
  more of the outstanding shares of Common Stock (the earlier of
  such dates being called the "Distribution Date"), the Rights will
  be evidenced, with respect to any of the Common Stock
  certificates outstanding as of the Record Date, by such Common
  Stock certificate with a copy of this Summary of Rights attached
  thereto.

       The Rights Agreement provides that, until the Distribution
  Date, the Rights will be transferred with and only with the
  Common Stock.  Until the Distribution Date (or earlier redemption
  or expiration of the Rights), new Common Stock certificates
  issued after the Record Date, upon transfer or new issuance of
  Common Stock, will contain a notation incorporating the Rights
  Agreement by reference.  Until the Distribution Date (or earlier
  redemption or expiration of the Rights), the surrender for
  transfer of any certificates for Common Stock, outstanding as of
  the Record Date, even without such notification or a copy of this
  Summary of Rights being 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
<PAGE>

  the Rights ("Right 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 Right Certificates alone will
  evidence the Rights.

       The Rights are not exercisable until the Distribution Date. 
  The Rights will expire on September 19, 2005 (the "Final
  Expiration Date"), unless the Final Expiration Date is extended
  or unless the Rights are earlier redeemed by the Company, in each
  case as described below.

       The Purchase Price payable, and the number of shares of
  Common 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, stock split, combination or reclassification
  of, the Common Stock, (ii) upon the grant to holders of Common
  Stock of certain rights, options or warrants to subscribe for or
  purchase shares of Common Stock at a price, or securities
  convertible into shares of Common Stock with a conversion price,
  less than the then current market price of the Common Stock or
  (iii) upon the distribution to holders of the Common Stock of
  evidences of indebtedness, cash (excluding regular quarterly or
  other periodic cash dividends paid out of the earnings or
  retained earnings of the Company), assets, stock (other than
  dividends payable in shares of Common Stock) or of subscription
  rights or warrants (other than those referred to above).

       In the event that, after the Distribution Date, the Company
  should consolidate or merge with and into any other person and
  the Company is not the surviving company, or, if the Company
  should be the surviving company, all or part of the Company's
  Common Stock is changed or exchanged for securities of any other
  person or if 50% or more of its consolidated assets or earning
  power are sold, proper provision will be made so that each holder
  of a Right will thereafter have the right to receive, upon the
  exercise thereof at the then current Purchase Price, that number
  of shares of common stock of the acquiring company which at the
  time of such transaction will have a market value of two times
  the Purchase Price.  In the event that any person becomes an
  Acquiring Person, proper provision shall be made so that each
  holder of a Right, other than Rights beneficially owned by the
  Acquiring Person or any Affiliate or Associate of an Acquiring
  Person (which will thereafter be void), will thereafter have the
  right to receive upon the exercise thereof at the then current
  Purchase Price, that number of shares of Common Stock having a
  market value of two times the Purchase Price; provided, however,
  that Rights are not exercisable following the occurrence of such
  event until such time as the Rights are no longer redeemable by
  the Company as set forth below.

       At any time after a person or group becomes an Acquiring
  Person and prior to the acquisition by such person or group of
  50% or more of the outstanding Common Stock, 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 per Right (subject to adjustment).
<PAGE>


       With certain exceptions, no adjustment in the Purchase Price
  will be required until cumulative adjustments require an
  adjustment of at least 1% in such Purchase Price.  No fractional
  shares of Common Stock will be issued, and in lieu thereof, an
  adjustment in cash may be made based on the market price of the
  Common Stock on the last trading day prior to the date of
  exercise.

       At any time prior to the earlier of fourteen days following
  the date that any person or group becomes an Acquiring Person,
  (subject to extension by the Board of Directors of the Company),
  or the Final Expiration Date, the Board of Directors of the
  Company may redeem the Rights in whole, but not in part, at a
  price of $.005 per Right (the "Redemption Price"); provided, that
  if the Board authorizes redemption of the Rights after the first
  date of public announcement by the Company or an Acquiring Person
  that an Acquiring Person has become such, there must be
  Continuing Directors then in office and a majority of the
  Directors of the Board and a majority of the Continuing Directors
  must approve such redemption.  The redemption of the Rights may
  be made effective at such time, on such basis and with such
  conditions as the Board of Directors in its sole discretion may
  establish.  Immediately upon any redemption of the Rights, the
  right to exercise the Rights will terminate and the only right of
  the holders of Rights will be to receive the Redemption Price.

       Prior to the Distribution Date, the terms of the Rights
  Agreement may be amended by the Board of Directors of the Company
  without the consent of the holders of the Rights or holders of
  the Common Stock.  From and after the Distribution Date, the
  terms of the Rights Agreement may be amended by the Company
  without the consent of the holders of the Rights or holders of
  the Common Stock in any manner which the Company may deem
  necessary or desirable so long as such supplement or amendment
  does not adversely affect the interest of Rights holders (other
  than the Acquiring Person or any Associate or Affiliates), and
  provided that such supplement or amendment may not lengthen the
  time period for redemption of the Rights if the Rights are not
  then redeemable and provided that there must be Continuing
  Directors then in office and that a majority of the Board and a
  majority of the Continuing Directors must approve such amendment. 
  The Company may at any time prior to such time as a person or
  group of affiliated or associated persons becomes an Acquiring
  Person lower the threshold for a person or group becoming an
  Acquiring Person from 15% to not less than the greater of (i) any
  percentage greater than the largest percentage of the outstanding
  shares of Common Stock then known to the Company to be
  beneficially owned by any such person or group of affiliated or
  associated persons and (ii) 10%.  In no case shall any amendment
  or supplement at any time decrease the Redemption Price or the
  period of time remaining until the Final Expiration Date.

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

       A copy of the Rights Agreement is available free of charge
<PAGE>

  from the Company.  This summary description of the Rights does
  not purport to be complete and is qualified in its entirety by
  reference to the Rights Agreement, which is hereby incorporated
  herein by reference.
