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

               On August 2, 1994, the Board of Directors of Mississippi
          Chemical Corporation, a Mississippi corporation (the "Company"),
          declared a dividend of one preferred share purchase right (a
          "Right") for each share of Common Stock, $0.01 par value, of the
          Company (the "Common Stock"). The dividend is payable on August
          15, 1994 to shareholders of record at the close of business on
          August 5, 1994 (the "Record Date") and with respect to all shares
          of Common Stock that become outstanding after the Record Date and
          prior to the earliest of the Separation Date (as defined below),
          the redemption of the Rights, the exchange of the Rights and the
          expiration of the Rights.  Except as set forth below and subject
          to adjustment as provided in the Rights Agreement (as defined
          below), each Right entitles the registered holder to purchase
          from the Company one one-hundredth of a share of the Company's
          Preferred Stock, Series A, $0.01 par value per share (the
          "Preferred Stock"), at an exercise price of $50.00 per share (the
          "Purchase Price").  The description and terms of the Rights are
          set forth in a Rights Agreement dated as of August 8, 1994 (the
          "Rights Agreement"), between the Company and Harris Trust and
          Savings Bank, as Rights Agent (the "Rights Agent").

               The Rights will be evidenced by Common Stock certificates
          and not separate certificates until the earlier to occur of (i)
          10 days following the date of public disclosure that a person or
          group, together with persons affiliated or associated with it (an
          "Acquiring Person"), has acquired, or obtained the right to
          acquire, beneficial ownership of 15% or more of the outstanding
          Common Stock (the "Stock Acquisition Date") and (ii) 10 days
          following commencement or disclosure of an intention to commence
          a tender offer or exchange offer by a person other than the
          Company and certain related entities if, upon consummation of the
          offer, such person or group, together with persons affiliated or
          associated with it, could acquire beneficial ownership of 25% or
          more of the outstanding Common Stock (the earlier of such dates
          being called "Separation Date").  Until the Separation Date (or
          earlier redemption or expiration of the Rights), the transfer of
          Common Stock will also constitute transfer of the associated
          Rights.  Following the Separation Date, separate certificates
          will evidence the Rights.

               The Rights will first become exercisable on the Separation
          Date (unless sooner redeemed).  The Rights will expire at the
          close of business on August 15, 2004 (the "Expiration Date"),
          unless earlier redeemed or exchanged by the Company as described
          below.

               The Purchase Price and the number of shares of Preferred
          Stock or other securities, cash or other 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 or
          distribution on, or a subdivision, combination or
          reclassification of, the Preferred Stock, (ii) upon the grant to
          holders of the Preferred Stock of certain rights, options,
          warrants to subscribe for Preferred Stock or securities
          convertible into Preferred Stock at less than the current market
          price of the Preferred Stock, or (iii) upon the distribution to
          holders of the Preferred Stock of other securities, cash
          (excluding regular periodic cash dividends at an annual rate not
          in excess of 125% of the annualized rate of cash dividends paid
          during the preceding fiscal year), property, evidences of
          indebtedness, or assets.

               In the event that, following the Separation Date, the
          Company is acquired in a merger or other business combination in
          which the Common Stock does not remain outstanding or is changed
          or 50% or more of its consolidated assets or earning power is
          sold, leased, exchanged, mortgaged, pledged or otherwise
          transferred or disposed of (in one transaction or a series of
          transactions) the Rights will "flip over" and entitle each holder
          of a Right to purchase, upon the exercise of the Right at the
          then-current Purchase Price, that number of shares of common
          stock of the acquiring company (or, in certain circumstances, one
          of its affiliates) which at the time of such transaction would
          have a market value of two times the Purchase Price.

               If (i) a person acquires beneficial ownership of 20% or more
          of the Common Stock, (ii) the Company is the surviving
          corporation in a merger with an Acquiring Person and the Common
          Stock remains outstanding and unchanged, or (iii) an Acquiring
          Person engages in a "self-dealing" transaction specified in the
          Rights Agreement, the Rights will "flip in" and entitle each
          holder of a Right, except as provided below, to purchase, upon
          exercise at the then-current Purchase Price, that number of
          shares of Common Stock having a market value of two times the
          Purchase Price.  

               Any "flip over" event or "flip in" event is a "Triggering
          Event."

               Any Rights beneficially owned at any time on or after the
          Separation Date by an Acquiring Person or an affiliate or
          associate of an Acquiring Person (whether or not such ownership
          is subsequently transferred) will become null and void upon the
          occurrence of the earlier of the Board of Directors decision to
          exchange the rights and a Triggering Event, and any holder of
          such Rights will have no right to exercise such Rights.

  


                                         -3-

               Under certain circumstances, the disinterested directors can
          approve a transaction with a specific shareholder and freeze the
          Rights in connection with that specific transaction.

               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.  Holders will
          have no right to receive fractional shares of Preferred Stock
          (other than fractions which are integral multiples of one one-
          hundredth of a share of Preferred Stock) upon the exercise of
          Rights.  In lieu of such fractional shares, an adjustment in cash
          may be made based on the market price of the Preferred Stock on
          the last trading date prior to the date of exercise.

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

               At any time prior to the earlier of (i) the closing of
          business on the tenth day following the time that it becomes
          public that an Acquiring Person has become such (with the
          possibility for the Board of Directors to extend this time for an
          additional 10 days) and (ii) the Expiration Date, the Company may
          redeem the Rights in whole, but not in part, at a price of $0.01
          per Right.  Immediately upon the action of the Company's Board of
          Directors electing to redeem the Rights, the right to exercise
          the Rights will terminate and the only right of the holders of
          Rights thereafter will be to receive the applicable redemption
          price.

               At any time any person becomes an Acquiring Person and prior
          to such time as such person, together with its affiliates becomes
          the beneficial owner of at least 50% of the Company's outstanding
          Common Stock, the Company may, provided that all necessary
          regulatory approvals have been obtained, exchange the Rights
          (other than Rights owned by such Acquiring Person which become
          null and void), in whole or in part, at a ratio of one share of
          Common Stock per Right, subject to adjustment.

               Until a Right is exercised, the holder has no rights as a
          shareholder of the Company, including, without limitation, the
          right to vote or to receive dividends or distributions.
          The Company may, without the approval of any holder of the
          Rights, but only if at that time the Board of Directors consists
          of a majority of disinterested directors, supplement or amend any

          provision of the Rights Agreement, except the redemption window,
          the Purchase Price or the redemption price.

               Preferred Stock purchasable upon exercise of the Rights will
          not be redeemable.  Each share of Preferred Stock will be
          entitled to a minimum preferential quarterly dividend payment of
          $25.00 per share but will be entitled to an aggregate dividend of
          100 times the dividend declared per share of Common Stock, if it
          is greater.  In the event of liquidation, the holders of the
          Preferred Stock will be entitled to a minimum preferential
          liquidation payment of $100.00 per share, but will be entitled to
          an aggregate payment of 100 times the payment made per share of
          Common Stock, if it is greater.  In the event of any merger or
          other business combination in which Common Stock is exchanged,
          each share of Preferred Stock will be entitled to receive 100
          times the amount received per share of Common Stock.  These
          rights are protected by customary antidilution provisions.

               Because of the nature of the Preferred Stock's dividend,
          liquidation and voting rights, the value of the one one-hundredth
          of a share of Preferred Stock purchasable upon exercise of each
          Right is intended to approximate the value of one share of Common
          Stock.

               The Rights have certain anti-takeover effects.  The Rights
          may cause substantial dilution to a person or group that attempts
          to acquire the Company on terms not approved by the Company's
          Board of Directors, except pursuant to an offer conditioned upon
          a substantial number of Rights being acquired.  The Rights should
          not interfere with any merger or other business combination
          approved by the Board of Directors prior to the time a person or
          group has acquired beneficial ownership of 15% or more of the
          Common Stock, because until such time, the Rights may be redeemed
          by the Company at $0.01 per Right.

               Pursuant to the Rights Agreement, Rights Certificates will
          not be mailed until as soon as practicable after the earlier of
          the tenth day after public announcement that a person or group
          has acquired beneficial ownership of 15% or more of the Common
          Stock or the tenth day after a person commences, or announces an
          intention to commence, a tender or exchange offer the
          consummation of which could result in a person beneficially
          owning 25% or more of the Common Stock.

                    A copy of the Rights Agreement is attached as Exhibit
          1.  A copy of the Rights Agreement will be available free of
          charge from the Company.  This summary description of the Rights
          does not purport to be complete and is qualified in its entirety
          by reference to the Rights Agreement, which is hereby
          incorporated herein by reference.

               the terms of which are hereby incorporated herein by
               reference and a copy of which is on file at the
               principal offices of the Company.  Under certain
               circumstances, as set forth in the Rights Agreement,
               such Rights will be evidenced by separate certificates
               and will no longer be evidenced by this certificate. 
               The Company will mail to the holder of this certificate
               a copy of the Rights Agreement without charge after
               receipt of a written request therefor.  Under certain
               circumstances, Rights beneficially owned by Acquiring
               Persons (as defined in the Rights Agreement) become
               null and void and the holder of such Rights (including
               any subsequent holder) shall not have any right to
               exercise the Rights.

                    (e)  After the Separation Date but prior to the
          Expiration Date, Rights shall be issued in connection with the
          issuance of Common Stock upon the exercise of stock options
          granted prior to the Separation Date or pursuant to other
          benefits under any employee plan or arrangement established prior
          to the Separation Date; provided, however, that if, pursuant to
          the terms of any option or other benefit plan, the number of
          shares issuable thereunder is adjusted after the Separation Date,
          the number of Rights issuable upon issuance of the shares shall
          be equal only to the number of shares which would have been
          issuable prior to the adjustment.

                    Section 4.  Form of Rights Certificates.

                    (a) The Rights Certificates (and the form of election
          to purchase shares and form of assignment) shall be in
          substantially the form attached hereto as Exhibit B 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

  


                                         -9-











  <PAGE>







          thereto or with any rule or regulation of any stock exchange on
          which the Rights may from time to time be listed or to conform to
          usage.  Subject to the provisions of this Agreement, the Rights
          Certificates, whenever issued, shall be dated as of the Record
          Date and on their face shall entitle the holders thereof to
          purchase such number of shares of Preferred Stock which shall be
          set forth therein at the Purchase Price set forth therein,
          subject to adjustment as provided in this Agreement.

                    (b)  Any Rights Certificate issued pursuant to Section
          3(a) of this Agreement that represents Rights beneficially owned
          by an Acquiring Person or that represents any Rights owned on or
          after the Separation Date by any Person who subsequently becomes
          an Acquiring Person and any Rights Certificate issued at any time
          upon the transfer of any Rights to an Acquiring Person or to any
          nominee of such Acquiring Person and any Rights Certificate
          issued pursuant to Section 6 or Section 13 of this Agreement upon
          transfer, exchange, replacement or adjustment of any other Rights
          Certificate referred to in this sentence, may contain the
          following legend:

                    The Rights represented by this Rights Certificate
               were issued to a Person who was or became an Acquiring
               Person.  This Rights Certificate and the Rights
               represented hereby may become void in the circumstances
               specified in Section 7(e) of the Rights Agreement.

                    Section 5.  Countersignature and Registration.

                    (a)  The Rights Certificates shall be executed on
          behalf of the Company by the Chairman of its Board of Directors,
          its President or any Vice President, either manually or by
          facsimile signature and shall have affixed thereto the Company's
          seal or a facsimile thereof which shall be attested by the
          Secretary or an Assistant Secretary of the Company, either
          manually or by facsimile signature.  Each Rights Certificate
          shall be manually countersigned by the Rights Agent and shall not
          be valid for any purpose unless so countersigned.  In case any
          officer of the Company who shall have signed any of the Rights
          Certificates shall cease to be such officer of the Company before
          countersignature by the Rights Agent and issuance and delivery by
          the Company, such Rights Certificates, nevertheless, may be

  


                                        -10-











  <PAGE>







          countersigned by the Rights Agent, and issued and delivered by
          the Company with the same force and effect as though the person
          who signed such Rights Certificates had not ceased to be such
          officer of the Company; and any Rights Certificate may be signed
          on behalf of the Company by any person who, at the actual date of
          the execution of such Rights Certificate, shall be a proper
          officer of the Company to sign such Rights Certificate, although
          at the date of the execution of this Rights Agreement any such
          person was not such an officer.

                    (b)  Following the Separation Date, the Rights Agent
          will keep or cause to be kept, at one of its offices, books for
          registration and transfer of the Rights Certificates issued
          hereunder.  Such books shall show the names and addresses of the
          respective holders of the Rights Certificates, the number of
          Rights evidenced by each of the Rights Certificates, and the
          certificate number and the date of each of the Rights
          Certificates.

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

                    (a) Subject to the provisions of Section 14 of this
          Agreement, at any time after the Close of Business on the
          Separation Date, and at or prior to the Close of Business on the
          Expiration Date, any Rights Certificate or Certificates may be
          transferred, split up, combined or exchanged for another Rights
          Certificate or Certificates, entitling the registered holder to
          purchase a like number of shares of Preferred Stock (or other
          securities, cash or other property, as the case may be) as the
          Rights Certificate or Certificates surrendered then entitled such
          holder (or former holder in the case of a transfer) to purchase. 
          Any registered holder desiring to transfer, split up, combine or
          exchange any Rights Certificate or Certificates shall make such
          request in writing delivered to the Rights Agent, and shall
          surrender the Rights Certificate or Certificates to be
          transferred, split up, combined or exchanged at the principal
          office of the Rights Agent designated for such purpose. 
          Thereupon, the Rights Agent shall countersign and deliver to the
          Person entitled thereto a Rights Certificate or Rights
          Certificates, as the case may be, as so requested.  The Company

  


                                        -11-











  <PAGE>







          may require payment of a sum sufficient to cover any tax or
          governmental charge that may be imposed in connection with any
          transfer, split up, combination or exchange of Rights
          Certificates.

                    (b)  Upon receipt by the Company and the Rights Agent
          of evidence reasonably satisfactory to them of the loss, theft,
          destruction or mutilation of a Rights Certificate, and, in case
          of loss, theft or destruction, of indemnity or security reason-
          ably satisfactory to them, and reimbursement to the Company and
          the Rights Agent of all reasonable expenses incidental thereto,
          and upon surrender to the Rights Agent and cancellation of the
          Rights Certificate if mutilated, the Company will execute and
          deliver a new Rights Certificate of like tenor to the Rights
          Agent for countersignature and delivery to the registered owner
          in lieu of the Rights Certificate so lost, stolen, destroyed or
          mutilated.

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

                    (a)  Each Right shall entitle (except as otherwise
          provided in this Agreement) the registered holder thereof, upon
          the exercise thereof as provided in this Agreement, to purchase,
          for the Purchase Price, at any time after the Separation Date and
          prior to the earliest of the Expiration Date, the Exchange Date
          and the Redemption Date, one one-hundredth share of Preferred
          Stock, subject to adjustment from time to time as provided in
          Section 13 of this Agreement, payable in lawful money of the
          United States of America in accordance with Paragraph (c) below.

                    (b)  Subject to Section 7(e), Section 23(a) and Section
          24 of this Agreement, the registered holder of any Rights
          Certificate may exercise the Rights evidenced thereby in whole or
          in part at any time after the Separation Date upon surrender of
          the Rights Certificate, with the form of election to purchase on
          the reverse side thereof including the certificate contained
          therein duly executed, to the Rights Agent at the principal
          office of the Rights Agent, together with payment of the Purchase
          Price for each one one-hundredth share of Preferred Stock as to
          which the Rights are exercised prior to the earliest of the
          Expiration Date, the Exchange Date and the Redemption Date.

                    (c)  Upon receipt of a Rights Certificate representing
          exercisable Rights, with the form of election to purchase
          including the certificate contained therein duly executed,
          accompanied by payment of the Purchase Price for the shares (or
          cash or other assets as the case may be) to be purchased and an
          amount equal to any applicable transfer tax in cash, or by
          certified check or bank draft payable to the order of the
          Company, the Rights Agent shall thereupon promptly:

                    (i)(A) requisition from any transfer agent for the
               Preferred Stock certificates for the number of one one-
               hundredths of a share of Preferred Stock to be purchased and
               the Company hereby irrevocably authorizes its transfer agent
               to comply with all such requests, or (B) requisition from
               the depositary agent depositary receipts representing such
               number of one one-hundredths of a share of Preferred Stock
               as are to be purchased (in which case certificates for the
               shares of Preferred Stock represented by such receipts shall
               be deposited by the transfer agent with the depositary
               agent) and the Company will direct the depositary agent to
               comply with such request;

                    (ii) requisition from the Company the amount of cash,
               if any, to be paid in lieu of fractional shares in
               accordance with Section 14 of this Agreement;

                    (iii) after receipt of such certificates or depositary
               receipts, cause the same to be delivered to or upon the
               order of the registered holder of such Rights Certificate,
               registered in such name or names as may be designated by
               such holder; and

                    (iv) after receipt, deliver such cash, if any, to
               or upon the order of the registered holder of such
               Rights Certificate.

          In the event that the Company is obligated to issue other
          securities (including shares of Common Stock) of the Company, pay
          cash and/or distribute other property pursuant to this Agreement,
          the Company will make all arrangements necessary so that such
          other securities, cash and/or other property are available for
          distribution by the Rights Agent, if and when appropriate.

                    (d)  In case the registered holder of any Rights
          Certificate shall exercise less than all the Rights evidenced
          thereby, a new Rights Certificate evidencing Rights equivalent to
          the Rights remaining unexercised shall be issued by the Rights
          Agent and delivered to the registered holder of such Rights
          Certificate or to his duly authorized assigns, subject to the
          provisions of Section 6 and Section 14 of this Agreement.

                    (e)  Notwithstanding anything in this Agreement to the
          contrary, upon the occurrence of the earlier of (x) the date on
          which the Board of Directors of the Company decides to exchange
          the Rights pursuant  to Section 24 of this Agreement and (y) a
          Triggering Event, any unexercised Rights that are or were, at any
          time on or after the earlier to occur of (i) the Separation Date
          and (ii) the Stock Acquisition Date, beneficially owned by an
          Acquiring Person (other than an Approved Acquiring Person who is
          not a party to the Triggering Event) or owned by any Person who
          subsequently becomes an Acquiring Person (other than an Approved
          Acquiring Person who is not a party to the Triggering Event)
          shall immediately become permanently null and void without any
          further action, and no holder of such Rights shall have any right
          whatsoever with respect to such Rights under this Agreement or
          otherwise.  The Company shall use all reasonable efforts to
          ensure that the provisions of this Section 7(e) and Section 4(b)
          of this Agreement are complied with, but shall have no liability
          to any holder of Rights Certificates or to any other Person as a
          result of its failure to make any determinations with respect to
          an Acquiring Person or its Affiliates, Associates or transferees
          hereunder.

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

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

                    Section 9.  Reservation and Availability of Preferred
          Stock.

                    (a) The Company covenants and agrees that it will cause
          to be reserved and kept available at all times out of its
          authorized and unissued shares of Preferred Stock or its
          authorized and issued shares of Preferred Stock held in its
          treasury, free from preemptive rights or any right of first
          refusal, the number of shares of Preferred Stock that will be
          sufficient to permit the exercise in full of all Rights from time
          to time outstanding.

                    (b)  So long as the shares of Preferred Stock issuable
          upon the exercise of the Rights may be listed on any national
          securities exchange, the Company shall use its best efforts to
          cause, from and after the time the Rights become exercisable, all
          shares reserved for such issuance to be listed on such exchange
          upon official notice of issuance upon such exercise.

                    (c)  The Company shall use its best efforts to:

                    (i)  file, as soon as practicable following the earlier
               of the Separation Date or as soon as is required by law, a
               registration statement under the Securities Act of 1933 (the

  


                                        -15-











  <PAGE>







               "Act"), with respect to the Preferred Stock purchasable upon
               exercise of the Rights on an appropriate form;

                    (ii)  cause such registration statement to become
               effective as soon as practicable after the filing; and

                    (iii)  cause such registration statement to remain
               effective (with a prospectus at all times meeting the
               requirements of the Act) until the earliest of (A) the date
               as of which Rights are no longer exercisable for such
               securities, (B) the Expiration Date and (C) the Redemption
               Date.

               The Company will also take all action necessary 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, for a period of time not to
          exceed ninety (90) days after the date set forth in clause (i) of
          the first sentence of this Section 9(c), the exercisability of
          the Rights in order to prepare and file such registration
          statements and permit them to become effective.  Upon 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.  Notwithstanding any provision
          of this Agreement to the contrary, the Rights shall not be
          exercisable in any jurisdiction unless the requisite
          qualification in that jurisdiction shall have been obtained and,
          if applicable, until a registration statement has been declared
          effective.

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

                    (e)  The Company further covenants and agrees that it
          will pay when due and payable any and all federal and state
          transfer taxes and charges which may be payable in respect of the
          issuance or delivery of the Rights Certificates and of any shares

  


                                        -16-











  <PAGE>







          of Preferred Stock upon the exercise of Rights.  The Company
          shall not, however, be required to pay any transfer tax which may
          be payable in respect of any transfer or delivery of Rights
          Certificates to a Person other than, the issuance or delivery of
          the shares of Preferred Stock, in respect of a name other than
          that of, the registered holder of the Rights Certificates
          evidencing Rights surrendered for exercise or the issuance or
          delivery of any certificates for shares of Preferred Stock in a
          name other than that of, the registered holder, upon the exercise
          of any Rights, until such tax shall have been paid (any such tax
          being payable by the holder of such Rights Certificate at the
          time of surrender) or until it has been established to the
          Company's satisfaction that no such tax is due.

                    Section 10.  Preferred Stock Record Date.  Each Person
          in whose name any certificate for shares of Preferred Stock is
          issued upon the exercise of Rights shall for all purposes be
          deemed to have become the holder of record of the shares of
          Preferred Stock represented thereby on, and such certificate
          shall be dated, the date upon which the Rights Certificate
          evidencing such Rights was duly surrendered and payment of the
          Purchase Price (and all applicable transfer taxes) was made;
          provided, however, that if the date of such surrender and payment
          is a date upon which the Preferred Stock transfer books of the
          Company are closed, such Person shall be deemed to have become
          the record holder of such shares on, and such certificate shall
          be dated, the next succeeding Business Day on which the Preferred
          Stock transfer books of the Company are open.

                    (i)  any Acquiring Person, directly or indirectly,
               shall merge into the Company or otherwise combine with
               the Company and the Company shall be the continuing or
               surviving corporation of such merger or combination and
               the Common Stock of the Company shall remain
               outstanding and unchanged, except pursuant to a merger
               or other combination involving an Approved Acquiring
               Person which was approved by a majority of the
               Continuing Directors; or

                    (ii)  any Person (other than the Company, any
               Subsidiary of the Company, any employee benefit plan of
               the Company or of any Subsidiary of the Company, or any
               entity organized, appointed or established pursuant to
               the terms of such plan) shall become the Beneficial
               Owner of 20% or more of the shares of Common Stock then
               outstanding (except pursuant to an offer for all
               outstanding shares of Common Stock at a price and upon
               such terms and conditions as a majority of the
               Continuing Directors determine to be in the best
               interests of the Company and its stockholders, other
               than such Acquiring Person); or

                    (iii)  any Acquiring Person shall, in one or a series
               of related transactions, directly or indirectly, transfer
               any assets to the Company or any of its Subsidiaries in
               exchange (in whole or in part) for shares of Common Stock or
               for securities exercisable or exchangeable for, or
               convertible into, shares of Common Stock or otherwise obtain
               from the Company or any of its Subsidiaries, with or without
               consideration, any additional Common Stock or other
               securities of the Company or securities of any of its
               subsidiaries or securities exercisable or exchangeable for,
               or convertible into, shares of Common Stock or other
               securities of the Company or securities of any of its
               Subsidiaries (other than an issuance upon conversion of
               convertible securities of the Company or any such Subsidiary
               that were not acquired from the Company or any such
               Subsidiary) except pursuant to a transaction or series of
               transactions approved by a majority of the Continuing
               Directors at a time when there are no Acquiring Persons
               other than Approved Acquiring Persons; or

                    (iv)  any Acquiring Person shall sell, purchase,
               lease, exchange, mortgage, pledge, otherwise transfer
               or dispose or acquire, from, to, with or of, the
               Company or any of its Subsidiaries, assets (including
               securities) on terms and conditions less favorable to
               the Company or such Subsidiary than the Company or such
               Subsidiary would be able to obtain in an arm's-length
               transaction with an unrelated third party, unless those

                    (v)  during the time when there is an Acquiring
               Person, there shall be any reclassification of
               securities (including any reverse stock split), or
               recapitalization of the Company, or any merger or
               consolidation of the Company with any of its
               Subsidiaries or any other transaction or series of
               transactions involving the Company (whether or not with
               or into or otherwise involving an Acquiring Person)
               which has the effect, directly or indirectly, of
               increasing by more than 1% the proportionate share of
               the outstanding shares of any class of equity
               securities of the Company or any of its Subsidiaries
               which is directly or indirectly owned by any Acquiring
               Person, except pursuant to a transaction or series of

               Directors at a time when there are no Acquiring Persons
               other than Approved Acquiring Persons; or

                    (vi)  any Acquiring Person shall, directly or
               indirectly, sell, purchase, lease, exchange, mortgage,
               pledge, otherwise transfer or acquire or dispose, in
               one transaction or a series of related transactions,
               from, to, with or of, the Company or any of its
               Subsidiaries, assets having an aggregate fair market
               value (as determined in good faith by a majority of the
               Continuing Directors) in excess of 10% or more of the
               total assets of the Company as shown on its
               consolidated balance sheet as of the end of the most
               recent fiscal quarter ending prior to the time the
               determination is being made to the stockholders of the
               Company, unless such sale or lease has been approved by
               a majority of the Continuing Directors; or

                    (vii)  during the time when there is an Acquiring
               Person, there shall be any distribution of assets or
               securities of the Company or of any of its
               Subsidiaries, in one transaction or a series of
               transactions, having an aggregate fair market value (as

               total assets of the Company as shown on its
               consolidated balance sheet as of the end of the most
               recent fiscal quarter ending prior to the time the
               determination is being made to the stockholders of the
               Company, unless the distribution is approved by a
               majority of the Continuing Directors; or

                    (viii)  any Acquiring Person, directly or
               indirectly, shall receive management fees or other
               compensation from the Company or any of its
               Subsidiaries other than compensation for full-time
               employment as a regular employee or directors' fees on
               the same basis as the other directors of the Company or
               any of its Subsidiaries, or receive the benefit of
               guarantees or other financial assistance or tax credits
               or other tax advantages from the Company or any of its
               Subsidiaries, unless those transactions are approved by
               a majority of the Continuing Directors; or

                    (ix)  during the time when there is an Acquiring
               Person, (1) there shall be any reduction in the annual rate
               of dividends paid on the Common Stock (except as necessary
               or appropriate, in the opinion of a majority of the
               Continuing Directors, for valid business reasons, to reflect
               any subdivision of the Common Stock or as required under the
               laws of the jurisdiction of incorporation of the Company) or
               (2) there shall be a failure to increase the annual rate of
               dividends as necessary to reflect any reclassification
               (including any reverse stock split), recapitalization,
               combination, reorganization or any similar transaction which
               has the effect of reducing the number of shares of
               outstanding Common Stock (except as necessary or
               appropriate, in the opinion of a majority of the Continuing
               Directors, for valid business reasons or to the extent such
               increase in the rate of dividends would be prohibited under
               the laws of the jurisdiction of incorporation of the
               Company);

          then, and in each case, subject to the provisions of Section 24
          of this Agreement, each holder of a Right, except as provided
          below and in Section 7(e) of this Agreement, shall thereafter

          have a right to receive, upon exercise of the Right at the then
          current Purchase Price, in accordance with the terms of this
          Agreement, in lieu of shares of Preferred Stock, 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 then number of one one-hundredths of a share of Preferred
          Stock for which a Right is then exercisable and dividing that
          product by (y) 50% of the Current Market Price per share of the
          Common Stock on the date on which the first of the events listed
          above in this subparagraph (a) occurs (such number of shares
          being herein referred to as the "ADJUSTMENT SHARES").

                    (b)  In the event that there shall not be sufficient
          treasury shares or authorized but unissued shares of Common Stock
          to permit the exercise in full of the Rights in accordance with
          the foregoing subparagraph (a), the Company shall take all such
          action as may be necessary to authorize additional shares of
          Common Stock for issuance upon exercise of the Rights; provided,
          however, that if the Company is unable to cause the authorization
          of a sufficient number of additional shares of Common Stock,
          then, in the event the Rights become so exercisable, the Company,
          with respect to each Right and to the extent necessary and
          permitted by applicable law and any agreements or instruments in
          effect on the date hereof to which the Company is a party, shall,
          upon the exercise of such Rights,

                         (i)  pay an amount in cash equal to the excess of
               (A) the product of (1) the number of Adjustment Shares,
               multiplied by (2) the Current Market Price of the Common
               Stock (such product being herein referred to as the "CURRENT
               VALUE"), over (B) the Purchase Price, in lieu of issuing
               shares of Common Stock and requiring payment therefor, or

                         (ii)  issue debt or equity securities, or a
               combination thereof, having a value equal to the Current
               Value, where the value of such securities shall be
               determined by a nationally recognized investment banking
               firm selected by the Board of Directors of the Company, and
               require the payment of the Purchase Price, or

                         (iii)  deliver any combination of cash, property,
               Common Stock and/or other securities having the requisite

               value, and require payment of all or any requisite portion
               of the Purchase Price.

                    To the extent that the Company determines that some
          action need be taken pursuant to clauses (i), (ii), or (iii) of
          the proviso of this Section 11(b), a majority of the Continuing
          Directors may suspend the exercisability of the Rights for a
          period of up to 45 days following the date on which the first of
          the events listed in Section 11(a)(i), (ii) or (iii) of this
          Agreement shall have occurred, in order to decide the appropriate
          form of distribution to be made pursuant to the above proviso and
          to determine the value thereof.  In the event of any 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 the time the suspension is no
          longer in effect.

                    Section 12.  The Flip-Over

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

                    (w) the Company shall consolidate with, or merge with
               and into, any other Person; or 

                    (x) 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 and, in
               connection with such merger, all or part of the shares of
               Common Stock shall be changed into or exchanged for stock or
               other securities of any other Person or cash or any other
               property; or 

                    (y) the Company shall effect a share exchange in which
               all or part of the Common Stock of the Company shall be
               changed into (including, without limitation, any conversion
               into or exchange for) securities of any other Person, cash
               or any other property; or

                    (z) the Company shall sell, lease, exchange, mortgage,
               pledge or otherwise transfer (or one or more of its
               Subsidiaries shall sell, lease, exchange, mortgage, pledge

               or otherwise transfer), in one or more transactions, assets
               or earning power aggregating more than 50% of the assets or
               earning power of the Company and its Subsidiaries (taken as
               a whole) to any other Person or Persons

          then, and in each such case, subject to the provisions of Section
          24 of this Agreement, except where the Person involved in the
          transaction is an Approved Acquiring Person and the transaction
          was approved by a majority of the Continuing Directors,

                    (i)  each holder of a Right, except as provided in
               Section 7(e) of this Agreement, shall thereafter have
               the right to receive, upon the exercise thereof at the
               then current Purchase Price in accordance with the
               terms of this Agreement, such number of shares of
               freely tradeable common stock of the Principal Party,
               free and clear of any lien, encumbrance or other
               adverse claim, as shall be equal to the result obtained
               by (1) multiplying the then current Purchase Price by
               the number of one one-hundredths of a share of
               Preferred Stock for which a Right is then exercisable
               (or the number of one one-hundredths of a share of
               Preferred Stock for which a Right was exercisable
               immediately prior to the occurrence of the Flip-In
               Event if a Flip-In Event has previously occurred) and
               dividing that product by (2) 50% of the Current Market
               Price per share of the common stock of such Principal
               Party on the date of consummation of the Flip-Over
               Event; 

                    (ii)  all common stock of any Person for which any
               Right may be exercised after consummation of a Business
               Combination as provided in this Section 12(a) shall, when
               issued upon exercise thereof in accordance with this
               Agreement, be duly and validly authorized and issued and
               fully paid and nonassessable;

                    (iii)  such Principal Party shall thereafter be
               liable for, and shall assume, by virtue of the
               Flip-Over Event, all the obligations and duties of the
               Company pursuant to this Agreement;


  


                                        -23-











  <PAGE>







                    (iv)  the term "Company" shall thereafter be
               deemed to refer to such Principal Party, it being
               specifically intended that the provisions of Section 13
               hereof shall apply to such Principal Party;

                    (v)  such Principal Party shall take such steps
               (including, but not limited to, the reservation of a
               sufficient number of shares of its common stock) in
               connection with such consummation as may be necessary
               to assure that the provisions hereof shall thereafter
               be applicable, as nearly as reasonably may be, in
               relation to its shares of common stock thereafter
               deliverable upon the exercise of the Rights; and

                    (vi)  the provisions of Section 11 of this
               Agreement shall be of no effect following the first
               occurrence of any Flip-Over Event.

                    (b)   "PRINCIPAL PARTY" shall mean:

                    (i)  in the case of any transaction described in
               (w), (x) or (y) of the first sentence of this Section
               12, the Person that is the issuer of any securities
               into which shares of Common Stock of the Company are
               converted or exchanged in such merger or consolidation,
               and if no securities are so issued, the Person that is
               the other party to the merger or consolidation; and

                    (ii)  in the case of any transaction described in
               (z) of the first sentence in this Section 12, the
               Person that is the party receiving the greatest portion
               of the assets or earning power transferred pursuant to
               such transaction or transactions;

          provided, however, that in any such case, (1) if the common stock
          of such Person is not at such time and has not been continuously
          over the preceding 12-month period registered under the
          Securities Exchange Act of 1934, as then in effect, and such
          Person is a direct or indirect Subsidiary of another Person the
          common stock of which is and has been so registered, "Principal
          Party" shall refer to such other Person; and (2) in case such
          Person is a Subsidiary, directly or indirectly, of more than one

  


                                        -24-











  <PAGE>







          Person, the common stocks of two or more of which are and have
          been so registered, "Principal Party" shall refer to whichever of
          such Persons is the issuer of the common stock having the
          greatest aggregate market value.

                    (c)  The Company shall not consummate any Flip-Over
          Event unless prior thereto the Company and each Principal Party
          and each other Person who may become a Principal Party shall have
          executed and delivered to the Rights Agent a supplemental
          agreement providing for the terms set forth in paragraphs (a) and
          (b) of this Section 12 and further providing that, as soon as
          practicable after the date of any Flip-Over Event, the Principal
          Party will:

                    (i)  prepare and file at its own expense a
               registration statement under the Act with respect to
               the Rights and the securities purchasable upon exercise
               of the Rights on an appropriate form, will use its best
               efforts to cause such registration statement to become
               effective as soon as practicable after such filing and
               will use its best efforts to cause such registration
               statement to remain effective (with a prospectus at all
               times meeting the requirements of the Act) until the
               earliest of the Expiration Date, the Exchange Date and
               the Redemption Date; and

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

          The Principal Party shall temporarily suspend, for a period of
          time not to exceed 90 days following the occurrence of a Flip--
          Over Event, the exercisability of the Rights in order to prepare
          an file the registration statement referred to in clause (i)
          above, and the Expiration Date shall be extended by the number of
          days of such suspension.  The provisions of this Section 12 shall
          similarly apply to successive Flip-Over Events.  In the event
          that a Flip-Over Event shall occur at any time after the
          occurrence of a Flip-In Event, the Rights which have not


  


                                        -25-

          theretofore been exercised shall thereafter become exercisable in
          the manner described in Section 12(a).

                    Section 13.  Adjustment of Purchase Price, Number and
          Kind of Shares or Number of Rights.  The Purchase Price, the
          number and kind of shares covered by each Right and the number of
          Rights outstanding are subject to adjustment from time to time as
          provided in this Section 13.

                    (a)  In the event the Company shall at any time after
          the date of this Agreement (A) declare a dividend or make a
          distribution on the Preferred Stock payable in shares of
          Preferred Stock into a larger number of shares, (B) subdivide the
          outstanding Preferred Stock into a larger number of shares, (C)
          combine the outstanding Preferred Stock into a smaller number of
          shares, or (D) issue any shares of its capital stock in a
          reclassification of the Preferred Stock (including any such
          reclassification in connection with a consolidation or merger in
          which the Company is the continuing or surviving corporation),
          then in each such event, except as otherwise provided in this
          Section 13(a), the Purchase Price in effect at the time of the
          record date for such dividend or distribution, or of the
          effective date of such subdivision, combination or
          reclassification, and the number and kind of shares of Preferred
          Stock or capital stock issuable on such date, shall be
          proportionately adjusted so that the holder of any Rights (except
          as provided in Section 7(e) of this Agreement) exercised on or
          after such time shall be entitled to receive upon payment of the
          Purchase Price in effect immediately prior to such date, the
          aggregate number and kind of shares of Preferred Stock or capital
          stock which, if such Rights had been exercised immediately prior
          to such date and at a time when the Preferred Stock transfer
          books of the Company were open, he would have owned upon such
          exercise and been entitled to receive by virtue of such dividend,
          distribution, subdivision, combination or reclassification.  If
          an event occurs which would require an adjustment under both
          Section 11(a) of this Agreement and this Section 13(a), the
          adjustment provided for in this Section 13(a) shall be in
          addition to, and shall be made prior to any adjustment required
          pursuant to Section 11(a).

                    (b)  In case the Company shall fix a record date for
          the issuance of rights, options or warrants to all holders of
          Preferred Stock entitling them to subscribe for or purchase
          Preferred Stock (or Equivalent Preferred Stock) or securities
          convertible into Preferred Stock or Equivalent Preferred Stock at
          a price per share of Preferred Stock or per share of Equivalent
          Preferred Stock (or having a conversion price per share, if a
          security convertible into Preferred Stock or Equivalent Preferred
          Stock) of less than the Current Market Price per share of
          Preferred Stock on such record date, the Purchase Price to be in
          effect after the record date shall be determined by multiplying
          the Purchase Price in effect immediately prior to the record date
          by a fraction, 

                    (1)  the numerator of which shall be the number of
               shares of Preferred Stock and Equivalent Preferred Stock (if
               any) outstanding on the record date, plus the number of
               shares of Preferred Stock and Equivalent Preferred Stock
               which the aggregate exercise price of the total number of
               shares of Preferred Stock and/or Equivalent Preferred Stock
               which are obtainable upon the exercise of the rights,
               options or warrants (and/or the aggregate initial conversion
               price of the convertible securities so offered) would
               purchase at the current market price; and 

                    (2)  the denominator of which shall be the number of
               shares of Preferred Stock and Equivalent Preferred Stock (if
               any) outstanding on the record date, plus the number of
               additional shares of Preferred Stock and/or Equivalent
               Preferred Stock which may be obtained upon exercise of the
               rights, options or warrants (or into which the convertible
               securities so offered are initially convertible).  

          If the subscription price may be paid in a consideration part or
          all of which shall be in a form other than cash, the value of
          such consideration shall be as determined in good faith by the
          Board of Directors of the Company, whose determination shall be
          described in a statement filed with the Rights Agent and shall be
          binding on the Rights Agent.  Shares of Preferred Stock or
          Equivalent Preferred Stock owned by or held for the account of
          the Company shall not be deemed outstanding for the purpose of
          any such computation.  Such adjustment shall be made successively

  


                                        -27-











  <PAGE>







          whenever such a record date is fixed; and in the event that
          rights, options or warrants are not issued following an
          adjustment, the Purchase Price shall again be adjusted to be the
          Purchase Price which would be in effect if the record date had
          not been fixed.

                    (c)  In case the Company shall fix a record date for a
          distribution to all holders of Preferred Stock (including any
          such distribution made in connection with a consolidation or
          merger in which the Company is the surviving corporation) of
          evidences of indebtedness, cash (other than a regular periodic
          cash dividend at an annual rate not in excess of 125% of the
          annual rate of the cash dividend paid on the Preferred Stock
          during the immediately preceding fiscal year), assets (other than
          a dividend payable in Preferred Stock, but including any dividend
          payable in stock other than Preferred Stock) or subscription
          rights or warrants (excluding those referred to in Section
          13(b)), 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, 

                    (1)  the numerator of which shall be the Current Market
               Price per share of Preferred Stock on such record date, less
               the fair market value (as determined in good faith by the
               Board of Directors of the Company, whose determination shall
               be described in a statement filed with the Rights Agent) of
               the portion of the cash, assets or evidences of indebtedness
               so to be distributed or of such subscription rights or
               warrants applicable to one share of Preferred Stock; and 

                    (2)  the denominator of which shall be such current
               market price per share of Preferred Stock.  

          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 be in effect if such record date had
          not been fixed.

                    (d)  Anything herein to the contrary notwithstanding,
          no adjustment in the Purchase Price shall be required unless such
          adjustment would require an increase or decrease of at least 1%

  


                                        -28-

          in the Purchase Price; provided, however, that any adjustments
          which by reason of this Section 13(d) are not required to be made
          shall be carried forward and taken into account in any subsequent
          adjustment.  All calculations under this Section 13 shall be made
          to the nearest cent or to the nearest ten-thousandth of a share
          of Common Stock or other share of one-millionth of a share of
          Preferred Stock, as the case may be.  Notwithstanding the first
          sentence of this Section 13(d), any adjustment required by this
          Section 13 shall be made no later than the earlier of (i) three
          years from the date of the transaction which mandates the
          adjustment or (ii) the earliest of the Expiration Date, the
          Exchange Date and the Redemption Date.

                    (e)  If as a result of an adjustment made pursuant to
          Section 11(a), the holder of any Rights thereafter exercised
          shall become entitled to receive any securities of the Company
          other than shares of Preferred Stock, thereafter the number of
          such other securities so receivable upon exercise of any Rights
          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 shares contained in Section 13(a) through
          (c), inclusive, and the provisions of Sections 7, 9, 10, 12 and
          14 of this Agreement with respect to the Preferred Stock shall
          apply on like terms to any such other securities.

                    (f)  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 Preferred Stock purchasable from
          time to time hereunder upon exercise of the Rights, all subject
          to further adjustment as provided in this Agreement.

                    (g)  Unless the Company shall have exercised its
          election as provided in Section 13(h), upon each adjustment of
          the Purchase Price as a result of the calculations made in
          Sections 13(b) and (c), each Right outstanding immediately prior
          to the making of such adjustment shall thereafter evidence the
          right to purchase, at the adjusted Purchase Price, that number of
          one one-hundredths of a share of Preferred Stock (calculated to
          the nearest one-millionth) obtained by 



  


                                        -29-











  <PAGE>







                    (i) multiplying (x) the number of one one-hundredths of
               a share of Preferred 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.

                    (h)  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
          Preferred Stock purchasable upon the exercise of a Right.  Each
          of the Rights outstanding after the adjustment in the number of
          Rights shall be exercisable for the number of one one-hundredths
          of a share of Preferred Stock for which a Right was exercisable
          immediately prior to such adjustment.  Each Right held of record
          prior to such adjustment of the number of Rights shall become
          that number of Rights (calculated to the nearest one-millionth)
          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
          Rights Certificates have been issued, shall be at least 10 days
          later than the date of the public announcement.  If Rights
          Certificates have been issued, upon each adjustment of the number
          of Rights pursuant to this Section 13(h), the Company shall, as
          promptly as practicable, cause to be distributed to holders of
          record of Rights Certificates on such record date Rights
          Certificates evidencing, subject to Section 14 hereof, the
          additional Rights to which such holders shall be entitled as a
          result of such adjustment, or, at the option of the Company,
          shall cause to be distributed to such holders of record in
          substitution and replacement for the Rights Certificates held by
          such holders prior to the date of adjustment, and upon surrender
          thereof, if required by the Company, new Rights Certificates
          evidencing all the Rights to which such holders shall be entitled

  


                                        -30-











  <PAGE>







          after such adjustment.  Rights Certificates so to be distributed
          shall be issued, executed and countersigned in the manner
          provided for herein (and may bear, at the option of the Company,
          the adjusted Purchase Price) and shall be registered in the names
          of the holders of record of Rights Certificates on the record
          date specified in the public announcement.

                    (i)  Irrespective of any adjustment or change in the
          Purchase Price or the number of one one-hundredths of a share of
          Preferred Stock issuable upon the exercise of the Rights, the
          Rights Certificates theretofore and thereafter issued may
          continue to express the Purchase Price per share and the number
          of shares which were expressed in the initial Rights Certificates
          issued hereunder.

                    (j)  Before taking any action that would cause an
          adjustment reducing the Purchase Price below the par value of the
          shares of Preferred 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
          may validly and legally issue fully paid and nonassessable shares
          of Preferred Stock at such adjusted Purchase Price.

                    (k)  In any case in which this Section 13 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 issuance to the
          holder of any Rights exercised after such record date the shares
          of Preferred Stock and other capital stock or securities, cash or
          property of the Company, if any, issuable upon such exercise over
          and above the shares of Preferred Stock and other capital stock
          or securities, cash or property 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 and other capital stock or securities, cash or
          property upon the occurrence of the event requiring such
          adjustment.

                    (l)  Anything in this Section 13 to the contrary
          notwithstanding, the Company shall be entitled to make such

  


                                        -31-











  <PAGE>







          reductions in the Purchase Price, in addition to those
          adjustments expressly required by this Section 13, as and to the
          extent that in its sole discretion the Company shall determine to
          be advisable in order that any (i) consolidation or subdivision
          of the Preferred Stock, (ii) issuance wholly for cash of any
          shares of Preferred Stock at less than the Current Market Price,
          (iii) issuance wholly for cash of shares of Preferred Stock or
          securities which by their terms are convertible into or
          exchangeable or exercisable for shares of Preferred Stock, (iv)
          stock dividends, or (v) issuance of rights, options or warrants
          referred to in this Section 13, hereafter made by the Company to
          holders of its Preferred Stock shall, if practicable, not be
          taxable to such stockholders.

                    (m)  The Company covenants and agrees that it shall not
          (i) consolidate with, (ii) merge with or into, or (iii) directly
          or indirectly sell, lease or otherwise transfer or dispose of, in
          one or more transactions, assets or earning power aggregating
          more than 50% of the assets or earning power of the Company and
          its Subsidiaries taken as a whole, to any other Person, if at the
          time of or immediately after such consolidation, merger, sale,
          lease, transfer or disposition there are any rights, warrants or
          other instruments or securities outstanding or agreements in
          effect which would substantially diminish or otherwise eliminate
          the benefits intended to be afforded by the Rights.

                    (n)  The Company covenants and agrees that, after the
          Stock Acquisition Date, it will not, except as permitted by
          Section 23 or Section 27 of this Agreement, take any action the
          purpose or effect of which is to diminish substantially or
          otherwise eliminate the benefits intended to be afforded by the
          Rights, unless such action is approved by a majority of the
          Continuing Directors.

                    (o)  Anything in this Agreement to the contrary
          notwithstanding, in the event that the Company shall at any time
          prior to the Separation Date (i) declare a dividend or
          distribution on the outstanding shares of Common Stock payable in
          shares of Common Stock, (ii) subdivide the outstanding shares of
          Common Stock, or (iii) combine the outstanding shares of Common
          Stock into a smaller number of shares, the number of Rights
          associated with each share of Common Stock then outstanding, or

  


                                        -32-











  <PAGE>







          issued or delivered thereafter but prior to the Separation Date,
          shall be proportionately adjusted so that the number of Rights
          thereafter associated with each share of Common Stock following
          any such event shall equal the result obtained by multiplying the
          number of Rights associated with each share of Common Stock
          immediately prior to such event by a fraction, (1) the numerator
          of which shall be the total number of shares of Common Stock
          outstanding immediately prior to the occurrence of the event and
          (2) the denominator of which shall be the total number of shares
          of Common Stock outstanding immediately following the occurrence
          of such event.

                    (p)  Whenever an adjustment is made as provided in
          Sections 11, 12 and 13 of this Agreement, the Company shall (a)
          promptly prepare a certificate setting forth such adjustment and
          a brief statement of the facts accounting for such adjustment,
          (b) promptly file with the Rights Agent and with each transfer
          agent for the Preferred Stock and the Common Stock a copy of such
          Certificate and (c) mail a brief summary thereof to each holder
          of a Rights Certificate in accordance with Section 26 of this
          Agreement.  The Rights Agent shall be fully protected in relying
          on any such certificate and on any adjustment therein contained.

                    Section 14.  Fractional Rights and Fractional Shares.

                    (a)  The Company shall not be required to issue
          fractional Rights or to distribute Rights Certificates which
          evidence fractional Rights.  In lieu of such fractional Rights,
          there shall be paid to the registered holders of the Rights
          Certificates with regard to which such fractional Rights would
          otherwise be issuable, an amount in cash equal to the same
          fraction of the Current Market Price of a whole Right as of the
          date on which such fractional Rights would have been otherwise
          issuable.

                    (b)  The Company shall not be required to issue
          fractions of shares of Preferred Stock (other than fractions
          which are integral multiples of one one-hundredth of a share of
          Preferred Stock) upon exercise of the Rights or to distribute
          certificates which evidence fractional shares of Preferred Stock
          (other than fractions which are integral multiples of one
          one-hundredth of a share of Preferred Stock).  In lieu of

  


                                        -33-











  <PAGE>







          fractional shares of Preferred Stock that are not integral
          multiples of one one-hundredth of a share of Preferred Stock, the
          Company may pay to the registered holders of Rights Certificates,
          at the time such Rights are exercised as herein provided, an
          amount in cash equal to the same fraction of the Current Market
          Price of one one-hundredth of a share of Preferred Stock as of
          the date of such exercise.

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

                    Section 15.  Rights of Action.  All rights of action in
          respect of this Agreement are vested in the respective registered
          holders of the Rights Certificates (and, prior to the Separation
          Date, the registered holders of the Common Stock); and any
          registered holder of any Rights Certificate (or, prior to the
          Separation Date, of the Common Stock) without the consent of the
          Rights Agent or of the holder of any other Rights Certificate
          (or, prior to the Separation 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 rights
          pursuant to 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 shall be entitled to specific performance of the obligations
          hereunder and injunctive relief against actual or threatened
          violations of the obligations hereunder of any Person subject to
          this Agreement.

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

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



  


                                        -34-











  <PAGE>







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

                    (c)  the Company and the Rights Agent may deem and
          treat the person in whose name a Rights Certificate (or, prior to
          the Separation Date, the associated Common Stock certificate) is
          registered as the absolute owner thereof and of the Rights
          evidenced thereby (notwithstanding any notations of ownership or
          writing on the Rights Certificates or the associated Common Stock
          certificate made by anyone other than the Company or the Rights
          Agent) for all purposes whatsoever, and neither the Company nor
          the Rights Agent shall be affected by any notice to the contrary;
          and

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


                    Section 17.  Rights Holder Not Deemed a Shareholder. 
          Except as otherwise expressly provided in this Agreement, no
          holder, as such, of any Rights Certificate shall be entitled to
          vote, receive dividends or be deemed for any purpose the holder
          of the shares of Preferred 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 Rights Certificate be construed to confer upon the
          holder of any Rights Certificate, as such, any of the rights of a
          shareholder of the Company or any right to vote for the election

  


                                        -35-

          of directors or upon any matter submitted to shareholders at any
          meeting thereof, or to give or withhold consent to any corporate
          action, or to receive notice of meetings or other actions
          affecting shareholders, or to receive dividends or subscription
          rights, or otherwise, until and only to the extent that the Right
          or Rights evidenced by such Rights Certificate shall have been
          exercised in accordance with the provisions of this Agreement.

                    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 disbursements 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 the acceptance and administration of this
          Agreement, including the costs and expenses of defending against
          any claim of liability in the premises.  The indemnification
          provided for hereunder shall survive the expiration of the Rights
          and the termination of this Agreement.

                    The Rights Agent shall be protected and shall incur no
          liability for or in respect of any action taken, suffered or
          omitted by it in connection with its administration of this
          Agreement in reliance upon any Rights Certificate or certificate
          for Common Stock or for other securities of the Company,
          instrument of assignment or transfer, power of attorney,
          endorsement, affidavit, letter, notice, direction, consent,
          certificate, statement, or other paper or document believed by it
          to be genuine and to be signed, executed and, where necessary,
          verified or acknowledged, by the proper Person or Persons.

                    Section 19.  Merger or Consolidation 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

  


                                        -36-











  <PAGE>







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

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

                    Section 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 Rights Certificates, by their
          acceptance thereof, shall be bound:

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


  


                                        -37-

                    (b)  Whenever in the performance of its duties under
          this Agreement the Rights Agent shall deem it necessary or
          desirable that any fact or matter (including, without limitation,
          the identity of any Acquiring Person) be proved or established by
          the Company prior to taking or suffering any action hereunder,
          such fact or matter (unless other evidence in respect thereof be
          herein specifically prescribed) may be deemed to be conclusively
          proved and established by a certificate signed by the Chairman of
          the Board, the President, any Vice President, the Treasurer, any
          Assistant Treasurer, the Secretary or any Assistant 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 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 facts or recitals contained in
          this Agreement or in the Rights Certificates or be required to
          verify the same (except as to its countersignature on such Rights
          Certificates), but all such statements and recitals are and shall
          be deemed to have been made by the Company only.

                    (e)  The Rights Agent shall not be under any
          responsibility in respect of the validity of this Agreement or
          the execution and delivery hereof (except the due execution
          hereof by the Rights Agent) or in respect of the validity or
          execution of any Rights Certificate (except its countersignature
          thereof); nor shall it be responsible for any breach by the
          Company of any covenant or condition contained in this Agreement
          or in any Rights Certificate; nor shall it be responsible for any
          adjustment required under the provisions of Sections 11 or 13 of
          this Agreement or responsible for the manner, method or amount of
          any such adjustment or the ascertaining of the existence of facts
          that would require any such adjustment (except with respect to
          the exercise of Rights evidenced by Rights Certificates after
          actual notice of any such adjustment); nor shall it by any act
          hereunder be deemed to make any representation or warranty as to
          the authorization or reservation of any shares of Common Stock or
          Preferred Stock to be issued pursuant to this Agreement or any

  


                                        -38-











  <PAGE>







          Rights Certificate or as to whether.any shares of Common Stock or
          Preferred Stock will, when so 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 the Chairman of the Board, the President,
          any Vice President, the Secretary, any Assistant Secretary, the
          Treasurer or any Assistant Treasurer of the Company, and to apply
          to such officers for advice or instructions in connection with
          its duties, and it shall not be liable for any action taken or
          suffered to be taken by it in good faith in accordance with
          instructions of any such officer.

                    (h)  The Rights Agent and any 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.

                    (j)  No provision of this Agreement shall require the
          Rights Agent to expend or risk its own funds or otherwise incur

  


                                        -39-











  <PAGE>







          any financial liability in the performance of any of its duties
          hereunder or in the exercise of its rights if there shall be
          reasonable grounds for believing that repayment of such funds or
          adequate indemnification against such risk or liability is not
          reasonably assured to it.

                    (k)  The Rights Agent shall not be required to take
          notice or be deemed to have notice of any fact event or
          determination under the Rights Agreement unless and until the
          Rights Agent shall be specifically notified in writing by the
          Company of such fact, event or determination.

                    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 and Preferred Stock by registered or certified mail, and to
          the holders of the Rights Certificates by first-class mail.  The
          Company may remove the Rights Agent or any successor Rights Agent
          upon 30 days' notice in writing, mailed to the Rights Agent or
          successor Rights Agent, as the case may be, and to each transfer
          agent of the Common Stock and Preferred Stock, by registered or
          certified mail, and to the holders of the Rights Certificates by
          first-class mail.  If the Rights Agent shall resign or be removed
          or shall otherwise become incapable of acting, the Company shall
          appoint a successor to the Rights Agent.  If the Company shall
          fail to make such appointment within a period of 30 days after
          giving notice of such removal or after it has been notified in
          writing of such resignation or incapacity by the resigning or
          incapacitated Rights Agent or by the holder of a Rights
          Certificate (who shall, with such notice, submit his Rights
          Certificate for inspection by the Company), then the registered
          holder of any Rights Certificate may apply to any court of
          competent jurisdiction for the appointment of a new Rights Agent. 
          Any successor Rights Agent, whether appointed by the Company or
          by such a court, shall be a corporation organized and doing
          business under the laws of the United States or of the State of
          Mississippi (or of any other state of the United States so long
          as such corporation is authorized to do business as a banking
          institution in the State of Mississippi), in good standing, which
          is authorized under such laws to exercise corporate trust powers
          and is subject to supervision or examination by federal or state

  


                                        -40-











  <PAGE>







          authority and which has at the time of its appointment as Rights
          Agent a combined capital and surplus of at least $50,000,000. 
          After appointment, the successor Rights Agent shall be vested
          with the same powers, rights, duties and responsibilities as if
          it had been originally named as Rights Agent without further act
          or deed; but the predecessor Rights Agent shall deliver and
          transfer to the successor Rights Agent any property at the time
          held by it hereunder, and execute and deliver any further
          assurance, conveyance, act or deed necessary for the purpose. 
          Not later than the effective date of any such appointment, the
          Company shall file notice thereof in writing with the predecessor
          Rights Agent and each transfer agent of the Common Stock and the
          Preferred Stock, and mail a notice thereof in writing to the
          registered holders of the Rights Certificates.  Failure to give
          any notice provided for in this Section 21, however, or any
          defect therein, shall not affect the legality or validity of the
          resignation or removal of the Rights Agent or the appointment of
          the successor Rights Agent, as the case may be.

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

                    Section 23.  Redemption and Termination.

                    (a)  The Board of Directors of the Company may, at its
          option, at any time prior to 5:00 P.M., Chicago, Illinois time,
          on the earlier of (i) the tenth day following the Stock
          Acquisition Date, subject to extension by the Board of Directors
          for a period of time up to, but not exceeding, ten additional
          days, or (ii) the Expiration Date, redeem all but not less than
          all the then outstanding Rights at a redemption price of $0.01
          per Right, appropriately adjusted to reflect any stock split,
          stock dividend or similar transaction occurring after the date
          hereof (such redemption price being hereinafter referred to as
          the "REDEMPTION PRICE"); provided, however, that at the time of

  


                                        -41-











  <PAGE>







          the redemption the Company's Board of Directors consists of a
          majority of Continuing Directors.  Notwithstanding anything in
          this Agreement to the contrary, no Rights may be exercised at any
          time that the Rights are subject to redemption in accordance with
          the terms of this Agreement.

                    (b)  Immediately upon the action of the Board of
          Directors of the Company extending the redemption period pursuant
          to Section 23(a)(i), evidence of which shall have been filed with
          the Rights Agent, the Company shall issue a press release
          indicating the date to which the Board of Directors has extended
          its right to redeem the Rights.

                    (c)  Notwithstanding the provisions of Section 23(a) of
          this Agreement, following the expiration of the Company's right
          to redeem the Rights due to the occurrence of a Stock Acquisition
          Date, and prior to the occurrence of a Triggering Event, the
          right of redemption may be reinstated by the Board of Directors
          of the Company to allow the Rights to be redeemed in connection
          with a merger or other business combination involving the Company
          which has been approved by the affirmative vote of 67% of the
          total number of outstanding shares of Common Stock which are not
          beneficially owned by any Acquiring Person; provided that at the
          time of the reinstatement the Board of Directors consists of a
          majority of Continuing Directors.  Once reinstated, the
          redemption shall be effected in the manner provided for in
          Sections 23(b) and (d) of this Agreement for the purpose of
          effectuating the approved merger or other business combination.

                    (d)  Immediately upon the action of the Board of
          Directors of the Company ordering the redemption of the Rights,
          evidence of which shall have been filed with the Rights Agent 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.  Within 10 days after the action of the Board of Directors
          ordering the redemption of the Rights, the Company shall give
          notice of such redemption to the Rights Agent and the holders of
          the then outstanding Rights by mailing such notice to all such
          holders at their last addresses as they appear upon the registry
          books of the Rights Agent or prior to the Separation 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.  In any case,
          failure to give such notice to any particular holder of Rights
          shall not affect the sufficiency of the notice to other holders
          of Rights.  Neither the Company nor any of its Affiliates or
          Associates may redeem for value any Rights at any time, in any
          manner, other than that specifically set forth in this Section
          23, and neither the Company nor any of its Affiliates or
          Associates may acquire or purchase for value any Rights at any
          time, in any manner, other than in connection with the purchase
          of shares of associated Common Stock prior to the Separation
          Date.

                    Section 24.  Exchange.

                    (a)  The Company may, at its option but subject to
          receipt of any required regulatory approvals, by action of the
          Board of Directors, 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 7(e)) for
          shares of Common Stock at an exchange ratio of one share of
          Common Stock per Right, appropriately adjusted to reflect any
          stock split, stock dividend or similar transaction occurring
          after the date hereof (such exchange ratio being herein referred
          to as the "EXCHANGE RATIO").  Notwithstanding the foregoing, the
          Board of Directors shall not be empowered to effect such exchange
          at any time after any Person (other than the Company, any
          Subsidiary of the Company any employee plan of the Company or of
          a Subsidiary of the Company or any Person holding Common Shares
          for or pursuant to the terms of any such employee plan), together
          with all Affiliates and Associates of such Person, becomes the
          Beneficial Owner of 50 percent or more of the Common Stock then
          outstanding.

                    (b)  Immediately upon the action of the Board of
          Directors of the Company ordering the exchange of any Rights
          pursuant to Section 24(a) 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

  


                                        -43-











  <PAGE>







          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
          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 Rights which will be exchanged.  Any partial exchange shall be
          effected pro rata based on the number of Rights (other than
          Rights which have become void pursuant to the provisions of
          Section 7(e)) held by each holder of Rights.

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

                    (d)  The Company shall not be required to issue
          fractions of shares of Common Stock or to distribute certificates
          which evidence fractional Common Stock.  In lieu of such
          fractional shares, 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.

                    Section 25.  Notice of Certain Events.

          dividend payable in stock of any class to the holders of
          Preferred Stock or to make any other distribution to the holders
          of Preferred Stock (other than a regular quarterly cash dividend
          at a rate not in excess of $20 per share), or (ii) to offer to
          the holders of Preferred Stock rights or warrants to subscribe
          for or to purchase any additional shares of Preferred Stock or
          shares of stock of any class or any other securities, rights or
          options, or (iii) to effect any reclassification of its Preferred
          Stock (other than a reclassification involving only the
          subdivision of outstanding shares of Preferred Stock), or (iv) to
          effect any Flip-Over Event, or (v) to effect the liquidation,
          dissolution or winding up of the Company, then, in each such
          case, the Company shall give to each holder of a Rights
          Certificate, in accordance with Section 26, a notice of such
          proposed action, which shall specify the record date for the
          purposes of such stock dividend, distribution of rights or

          Event, liquidation, dissolution, or winding up is to take place

          date for determining holders of the shares of Preferred Stock for
          purposes of such action, and in the case of any such other
          action, at least 20 days prior to the date of the taking of such
          proposed action or the date of participation therein by the
          holders of the shares of Preferred Stock whichever shall be the
          earlier.

                    (b)  Upon the occurrence of a Flip-In Event or a
          Flip-Over Event, the Company or Principal Party, as the case may
          be, shall as soon as practicable thereafter give to each holder
          of a Rights Certificate, to the extent feasible and in accordance
          with Section 26, a notice of the occurrence of such event and the
          consequences thereof to holders of Rights under Sections 11(a) or

               We, Coley L. Bailey, Chairman of the Board of Directors and
          Rosalyn B. Glascoe, Secretary, of Mississippi Chemical
          Corporation, a corporation organized and existing under the
          Mississippi Business Corporation Act, in accordance with the

               That pursuant to the authority conferred upon the Board of
          Directors by the Certificate of Incorporation of the said
          Corporation, the said Board of Directors on August 2, 1994,
          adopted the following resolution creating a series of 250,000
          shares of Preferred Stock designated as "Preferred Stock, Series

               RESOLVED, that pursuant to the authority vested in the Board
          of Directors of this Corporation in accordance with the
          provisions of its Certificate of Incorporation a series of

          "Preferred Stock") and the number of shares constituting such
          series shall be 250,000.

               Section 2.  Dividends and Distributions.

               (A)  Subject to the prior and superior rights of the holders
             of any shares of any series of preferred stock ranking prior
             and superior to the shares of Preferred Stock with respect to
             dividends, the holders of shares of Preferred Stock, in
             preference to the holders of common stock, $.01 par value per
             share, of the Corporation (the "Common Stock") and of any
             other junior stock, shall be entitled to receive, when, as and
             if declared by the Board of Directors out of funds legally
             available for the purpose, quarterly dividends payable in cash
             on the fifteenth day of March, June, September and December in
             each year (each such date being referred to herein as a
             "Quarterly Dividend Payment Date"), commencing on the first
             Quarterly Dividend Payment Date after the first issuance of a
             share or fraction of a share of Preferred Stock, in an amount
             per share (rounded to the nearest cent) equal to the greater
             of (a) $25.00 or (b) subject to the provision for adjustment
             hereinafter set forth, 100 times the aggregate per share
             amount of all cash dividends, and 100 times the aggregate per
             share amount (payable in kind) of all non-cash dividends or
             other distributions other than a dividend payable in shares of
             Common Stock or a subdivision of the outstanding shares of
             Common Stock (by reclassification or otherwise), declared on
             the Common Stock since the immediately preceding Quarterly
             Dividend Payment Date or, with respect to the first Quarterly
             Dividend Payment Date, since the first issuance of any share
             or fraction of a share of Preferred Stock.  In the event the
             Corporation shall at any time on or after August 15, 1994
             declare or pay any dividend on Common Stock payable in shares
             of Common Stock, or effect a subdivision of combination or
             consolidation of the outstanding shares of Common Stock (by
             reclassification or otherwise than by payment of a dividend in
             shares of Common Stock) into a greater or lesser number of
             shares of Common Stock, then in each such case the amount to
             which holders of shares of Preferred Stock were entitled
             immediately prior to such event under clause (b) of the
             preceding sentence shall be adjusted by multiplying such
             amount by a fraction the numerator of which is the number of

             shares of Common Stock outstanding immediately after such
             event and the denominator of which is the number of shares of
             Common Stock that were outstanding immediately prior to such
             event.

               (B)  The Corporation shall declare a dividend or
             distribution on the Preferred Stock as provided in paragraph
             (A) of this Section immediately after it declares a dividend
             or distribution on the Common Stock (other than a dividend
             payable in shares of Common Stock); provided that, in the
             event no dividend or distribution shall have been declared on
             the Common Stock during the period between any Quarterly
             Dividend Payment Date and the next subsequent Quarterly
             Dividend Payment Date, a dividend of $25.00 per share on the
             Preferred Stock shall nevertheless be payable on such
             subsequent Quarterly Dividend Payment Date.

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

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

               (A)  Subject to the provision for adjustment hereinafter set
             forth, each share of Preferred Stock shall entitle the holder
             thereof to 100 votes on all matters submitted to a vote of the
             stockholders of the Corporation.  In the event the Corporation
             shall at any time on or after August 15, 1994 declare or pay
             any dividend on Common Stock payable in shares of Common
             Stock, or effect a subdivision or combination or consolidation
             of the outstanding shares of Common Stock (by reclassification
             or otherwise than by payment of a dividend in shares of Common
             Stock) into a greater or lesser number of shares of Common
             Stock, then in each such case the number of votes per share to
             which holders of shares of Preferred Stock were entitled
             immediately prior to such event shall be adjusted by
             multiplying such number by a fraction, the numerator of which
             is the number of shares of Common Stock outstanding
             immediately after such event, and the denominator of which is
             the number of shares of Common Stock that were outstanding
             immediately prior to such event.

               (B)  Except as otherwise provided herein or by law, the
             holders of shares of Preferred Stock and the holders of shares
             of Common Stock shall vote together as one class on all
             matters submitted to a vote of stockholders of the
             Corporation.

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

               Section 4.  Certain Restrictions.

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

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

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

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

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

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

               Section 5.  Reacquired Shares.  Any shares of Preferred
          Stock purchased or otherwise acquired by the Corporation in any
          manner whatsoever shall be retired and cancelled promptly after
          the acquisition thereof.  All such shares shall upon their
          cancellation become authorized but unissued shares of preferred
          stock and may be reissued as part of a new series of preferred
          stock to be created by resolution or resolutions of the Board of
          Directors, subject to the conditions and restrictions on issuance
          set forth herein.

               Section 6.  Liquidation, Dissolution or Winding Up.  Upon
          any liquidation, dissolution or winding up of the Corporation, no
          distribution shall be made (1) to the holders of shares of stock
          ranking junior (either as to dividends or upon liquidation,
          dissolution or winding up) to the Preferred Stock unless, prior
          thereto, the holders of shares of Preferred Stock shall have
          received $100.00 per share, plus an amount equal to accrued and
          unpaid dividends and distributions thereon, whether or not
          declared, to the date of such payment, provided that the holders
          of shares of Preferred Stock shall be entitled to receive an
          aggregate amount per share, subject to the provision for
          adjustment hereinafter set forth, equal to 100 times the
          aggregate amount to be distributed per share to holders of Common
          Stock, or (2) to the holders of stock ranking on a parity (either
          as to dividends or upon liquidation, dissolution or winding up)
          with the Preferred Stock, except distributions made ratably on
          the Preferred Stock and all other such parity stock in proportion
          to the total amounts to which the holders of all such shares are
          entitled upon such liquidation, dissolution or winding up.  In
          the event the Corporation shall at any time on or after August
          15, 1994 declare or pay any dividend on Common Stock payable in
          shares of Common Stock, or effect a subdivision or combination or
          consolidation of the outstanding shares of Common Stock (by
          reclassification or otherwise than by payment of a dividend in
          shares of Common Stock) into a greater or lesser number of shares
          of Common Stock, then in each such case the aggregate amount to
          which holders of shares of Preferred Stock were entitled
          immediately prior to such event under the proviso in clause (1)
          of the preceding sentence shall be adjusted by multiplying such
          amount by a fraction the numerator of which is the number of
          shares of Common Stock outstanding immediately after such event


  


                                         A-6

          and the denominator of which is the number of shares of Common
          Stock that were outstanding immediately prior to such event.

               Section 7.  Consolidation, Merger, etc.  In case the
          Corporation shall enter into any consolidation, merger,
          combination or other transaction in which the shares of Common
          Stock are exchanged for or changed into other stock or
          securities, cash and/or any other property, then in any such case
          the shares of Preferred Stock then outstanding shall at the same
          time be similarly exchanged or changed in an amount per share
          (subject to the provision for adjustment hereinafter set forth)
          equal to 100 times the aggregate amount of stock, securities,
          cash and/or any other property (payable in kind), as the case may
          be, into which or for which each share of Common Stock is changed
          or exchanged.  In the event the Corporation shall at any time on
          or after August 15, 1994 declare or pay any dividend on Common
          Stock payable in shares of Common Stock, or effect a subdivision
          or combination or consolidation of the outstanding shares of
          Common Stock (by reclassification or otherwise) into a greater or
          lesser number of shares of Common Stock, then in each such case
          the amount set forth in the preceding sentence with respect to
          the exchange or change of shares of Preferred Stock shall be
          adjusted by multiplying such amount by a fraction the numerator
          of which is the number of shares of Common Stock outstanding
          immediately after such event and the denominator of which is the
          number of shares of Common Stock that were outstanding
          immediately prior to such event.

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

               Section 9.  Amendment.  The Certificate of Incorporation of
          the Corporation shall not be amended in any manner which would
          materially alter or change the powers, preferences or special
          rights of the Preferred Stock so as to affect them adversely
          without the affirmative vote of the holders of two-thirds or more
          of the outstanding shares of Preferred Stock, voting together as
          a single class.

                           MISSISSIPPI CHEMICAL 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 August 8, 1994 (the "RIGHTS AGREEMENT")
          between Mississippi Chemical Corporation, a Mississippi
          corporation (the "COMPANY"), and Harris Trust and Savings Bank
          (the "RIGHTS AGENT"), unless notice of redemption shall have been
          previously given by the Company, to purchase from the Company at
          any time after the Separation Date (as such term is defined in
          the Rights Agreement) and prior to 5:00 P.M. (Chicago, Illinois
          time) on August 15, 2004 at the principal corporate trust office
          of the Rights Agent, or at the office of its successor as Rights
          Agent, one one-hundredth of a fully paid nonassessable share of
          the Preferred Stock, Series A (the "PREFERRED STOCK"), par value

          $0.01 per share, of the Company, at a purchase price of $50.00
          per one one-hundredth share (the "PURCHASE PRICE") upon
          presentation and surrender of this Rights Certificate with the
          Form of Election to Purchase duly executed.  The Purchase Price
          may be paid in cash or by certified bank check or money order
          payable to the order of the Company.

               The number of Rights evidenced by this Rights Certificate
          (and the number of shares of Preferred Stock which may be
          purchased upon exercise thereof) and the Purchase Price set forth
          above have been determined as of August 15, 1994, based on the
          Common Stock of the Company as constituted at such date.  As
          provided in the Rights Agreement, the Purchase Price and the
          number of shares of Preferred Stock or other securities, cash or
          other property which may be purchased upon the exercise of the
          Rights evidenced by this Rights Certificate are subject to
          modification and adjustment upon the happening of certain events.

               If the Rights evidenced by this Rights Certificate are or
          were formerly beneficially owned, on or after the earlier of the
          Separation Date and the Stock Acquisition Date, by an Acquiring
          Person or an Affiliate, Associate or direct or indirect
          transferee of an Acquiring Person, such Rights may become null
          and void and the holder of any such Right (including any
          subsequent holder) shall not have any right with respect to such
          Right.

               This Rights Certificate is subject to all of the terms,
          provisions and conditions of the Rights Agreement, which terms,
          provisions and conditions are hereby incorporated herein by
          reference and made a part hereof and to which Rights Agreement
          reference is hereby made for a full description of the rights,
          limitations of rights, obligations, duties and immunities

          above-mentioned office of the Rights Agent.

          Certificates, upon surrender at the principal corporate trust

          Certificate or Rights Certificates of like tenor and date
          evidencing Rights entitling the holder to purchase a like
          aggregate number of shares of Preferred Stock or other property
          as the Rights evidenced by the Rights Certificate or Rights
          Certificates surrendered entitled such holder to purchase.  If
          this Rights Certificate shall be exercised in part, the holder
          shall be entitled to receive upon surrender hereof another Rights
          Certificate or Rights Certificates for the number of whole Rights
          not exercised.

               Subject to the provisions of the Rights Agreement, the
          Rights evidenced by this Certificate may be redeemed by the
          Company at its option at a redemption price of $0.01 per Right at
          any time prior to the earlier of (i) the close of business on the
          tenth day following the time it becomes public that an Acquiring
          Person has become such (with the possibility of an extension for
          an additional ten (10) days) and (ii) the Expiration Date.

               No fractional shares of Preferred Stock (other than
          fractions that are integral multiples of one one-hundredth of
          share of Preferred Stock, which may, at the election of the
          Company, be evidenced by depository receipts) are required to be
          issued upon the exercise of any Right or Rights evidenced hereby,
          but in lieu thereof the Company may elect to make a cash payment,
          as provided in the Rights Agreement.

               No holder of this Rights Certificate, as such, shall be
          entitled to vote or to receive dividends or shall be deemed, for
          any purpose, the holder of Preferred Stock or of any other
          securities, cash or property which may at any time be issuable on
          the exercise hereof, nor shall anything contained in the Rights
          Agreement or this Certificate be construed to confer upon the
          holder hereof, as such, any of the rights of a stockholder of the
          Company, including, without limitation, 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
          the Rights Agreement), or to receive dividends or subscription
          rights, or to institute, as a holder of Preferred Stock or other
          securities issuable on the exercise of the Rights represented by

                            SUMMARY OF RIGHTS TO PURCHASE
                                   PREFERRED STOCK

             On August 2, 1994, the Board of Directors of Mississippi
          Chemical Corporation, a Mississippi corporation (the "COMPANY"),
          declared a dividend of one preferred share purchase right (a
          "RIGHT") for each share of Common Stock, $0.01 par value, of the
          Company (the "COMMON STOCK"). The dividend is payable on August
          15, 1994 to shareholders of record at the close of business on
          August 5, 1994 (the "RECORD DATE") and with respect to all shares
          of Common Stock that become outstanding after the Record Date and
          prior to the earliest of the Separation Date (as defined below),
          the redemption of the Rights, the exchange of the Rights and the
          expiration of the Rights.  Except as set forth below and subject
          to adjustment as provided in the Rights Agreement (as defined
          below), each Right entitles the registered holder to purchase
          from the Company one one-hundredth of a share of the Company's
          Preferred Stock, Series A, $0.01 par value per share (the
          "PREFERRED STOCK"), at an exercise price of $50.00 per share (the
          "PURCHASE PRICE").  The description and terms of the Rights are
          set forth in a Rights Agreement dated as of August 8, 1994 (the
          "RIGHTS AGREEMENT"), between the Company and Harris Trust and
          Savings Bank, as Rights Agent (the "RIGHTS AGENT").

             The Rights will be evidenced by Common Stock certificates and
          not separate certificates until the earlier to occur of (i) 10
          days following the date of public disclosure that a person or
          group, together with persons affiliated or associated with it (an
          "ACQUIRING PERSON"), has acquired, or obtained the right to
          acquire, beneficial ownership of 15% or more of the outstanding
          Common Stock (the "STOCK ACQUISITION DATE") and (ii) 10 days
          following commencement or disclosure of an intention to commence
          a tender offer or exchange offer by a person other than the
          Company and certain related entities if, upon consummation of the
          offer, such person or group, together with persons affiliated or
          associated with it, could acquire beneficial ownership of 25% or
          more of the outstanding Common Stock (the earlier of such dates
          being called "SEPARATION DATE").  Until the Separation Date (or
          earlier redemption or expiration of the Rights), the transfer of
          Common Stock will also constitute transfer of the associated
          Rights.  Following the Separation Date, separate certificates
          will evidence the Rights.

  


                                         C-1

             The Rights will first become exercisable on the Separation
          Date (unless sooner redeemed).  The Rights will expire at the
          close of business on August 15, 2004 (the "EXPIRATION DATE"),
          unless earlier redeemed or exchanged by the Company as described
          below.

             The Purchase Price and the number of shares of Preferred Stock
          or other securities, cash or other 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 or
          distribution on, or a subdivision, combination or
          reclassification of, the Preferred Stock, (ii) upon the grant to
          holders of the Preferred Stock of certain rights, options,
          warrants to subscribe for Preferred Stock or securities
          convertible into Preferred Stock at less than the current market
          price of the Preferred Stock, or (iii) upon the distribution to
          holders of the Preferred Stock of other securities, cash
          (excluding regular periodic cash dividends at an annual rate not
          in excess of 125% of the annualized rate of cash dividends paid
          during the preceding fiscal year), property, evidences of
          indebtedness, or assets.

             In the event that, following the Separation Date, the Company
          is acquired in a merger or other business combination in which
          the Common Stock does not remain outstanding or is changed or 50%
          or more of its consolidated assets or earning power is sold,
          leased, exchanged, mortgaged, pledged or otherwise transferred or
          disposed of (in one transaction or a series of transactions) the
          Rights will "FLIP OVER" and entitle each holder of a Right to
          purchase, upon the exercise of the Right at the then-current
          Purchase Price, that number of shares of common stock of the
          acquiring company (or, in certain circumstances, one of its
          affiliates) which at the time of such transaction would have a
          market value of two times the Purchase Price.

             If (i) a person acquires beneficial ownership of 20% or more
          of the Common Stock, (ii) the Company is the surviving
          corporation in a merger with an Acquiring Person and the Common
          Stock remains outstanding and unchanged, or (iii) an Acquiring
          Person engages in a "SELF-DEALING" transaction specified in the
          Rights Agreement, the Rights will "FLIP IN" and entitle each
          holder of a Right, except as provided below, to purchase, upon
          exercise at the then-current Purchase Price, that number of


  


                                         C-2









  <PAGE>







          shares of Common Stock having a market value of two times the
          Purchase Price.  

             Any "flip over" event or "flip in" event is a "TRIGGERING
          EVENT."

             Any Rights beneficially owned at any time on or after the
          Separation Date by an Acquiring Person or an affiliate or
          associate of an Acquiring Person (whether or not such ownership
          is subsequently transferred) will become null and void upon the
          occurrence of the earlier of the Board of Directors decision to
          exchange the rights and a Triggering Event, and any holder of
          such Rights will have no right to exercise such Rights.

             Under certain circumstances, the disinterested directors can
          approve a transaction with a specific shareholder and freeze the
          Rights in connection with that specific transaction.

             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.  Holders will
          have no right to receive fractional shares of Preferred Stock
          (other than fractions which are integral multiples of one one-
          hundredth of a share of Preferred Stock) upon the exercise of
          Rights.  In lieu of such fractional shares, an adjustment in cash
          may be made based on the market price of the Preferred Stock on
          the last trading date prior to the date of exercise.

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

             At any time prior to the earlier of (i) the closing of
          business on the tenth day following the time that it becomes
          public that an Acquiring Person has become such (with the
          possibility for the Board of Directors to extend this time for an
          additional 10 days) and (ii) the Expiration Date, the Company may
          redeem the Rights in whole, but not in part, at a price of $0.01
          per Right.  Immediately upon the action of the Company's Board of
          Directors electing to redeem the Rights, the right to exercise

  


                                         C-3









  <PAGE>







          the Rights will terminate and the only right of the holders of
          Rights thereafter will be to receive the applicable redemption
          price.

             At any time any person becomes an Acquiring Person and prior
          to such time as such person, together with its affiliates becomes
          the beneficial owner of at least 50% of the Company's outstanding
          Common Stock, the Company may, provided that all necessary
          regulatory approvals have been obtained, exchange the Rights
          (other than Rights owned by such Acquiring Person which become
          null and void), in whole or in part, at a ratio of one share of
          Common Stock per Right, subject to adjustment.

             Until a Right is exercised, the holder has no rights as a
          shareholder of the Company, including, without limitation, the
          right to vote or to receive dividends or distributions.
          The Company may, without the approval of any holder of the
          Rights, but only if at that time the Board of Directors consists
          of a majority of disinterested directors, supplement or amend any
          provision of the Rights Agreement, except the redemption window,
          the Purchase Price or the redemption price.

             Preferred Stock purchasable upon exercise of the Rights will
          not be redeemable.  Each share of Preferred Stock will be
          entitled to a minimum preferential quarterly dividend payment of
          $25.00 per share but will be entitled to an aggregate dividend of
          100 times the dividend declared per share of Common Stock, if it
          is greater.  In the event of liquidation, the holders of the
          Preferred Stock will be entitled to a minimum preferential
          liquidation payment of $100.00 per share, but will be entitled to
          an aggregate payment of 100 times the payment made per share of
          Common Stock, if it is greater.  In the event of any merger or
          other business combination in which Common Stock is exchanged,
          each share of Preferred Stock will be entitled to receive 100
          times the amount received per share of Common Stock.  These
          rights are protected by customary antidilution provisions.

             Because of the nature of the Preferred Stock's dividend,
          liquidation and voting rights, the value of the one one-hundredth
          of a share of Preferred Stock purchasable upon exercise of each
          Right is intended to approximate the value of one share of Common
          Stock.

             The Rights have certain anti-takeover effects.  The Rights may
          cause substantial dilution to a person or group that attempts to
          acquire the Company on terms not approved by the Company's Board
          of Directors, except pursuant to an offer conditioned upon a
          substantial number of Rights being acquired.  The Rights should
          not interfere with any merger or other business combination
          approved by the Board of Directors prior to the time a person or
          group has acquired beneficial ownership of 15% or more of the
          Common Stock, because until such time, the Rights may be redeemed
          by the Company at $0.01 per Right.

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