                                         of

                    SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

                                         of
                                     AMGEN INC.

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



             Amgen Inc., a corporation organized and existing under the
        General Corporation Law of the State of Delaware (hereinafter called
        the "Corporation"), hereby certifies that the following resolution
        was adopted by the Board of Directors of the Corporation as required
        by Section 151 of the General Corporation Law at a meeting duly
        called and held on February 18, 1997.

                  RESOLVED, that pursuant to the authority granted to and
        vested in the Board of Directors of this Corporation (hereinafter
        called the "Board of Directors" or the "Board") in accordance with
        the provisions of the Certificate of Incorporation, the Board of
        Directors hereby creates a series of Preferred Stock, par value
        $.0001 per share (the "Preferred Stock"), of the Corporation and
        hereby states the designation and number of shares, and fixes the
        relative rights, preferences, and limitations thereof as follows:

             Series A Junior Participating Preferred Stock:

                  Section 1.  Designation and Amount.  The shares of such
        series shall be designated as "Series A Junior Participating
        Preferred Stock" (the "Series A Preferred Stock") and the number of
        shares constituting the Series A Preferred Stock shall be 750,000.
        Such number of shares may be increased or decreased by resolution of
        the Board of Directors; provided, that no decrease shall reduce the
        number of shares of Series A Preferred Stock to a number less than
        the number of shares then outstanding plus the number of shares
        reserved for issuance upon the exercise of outstanding options,
        rights or warrants or upon the conversion of any outstanding
        securities issued by the Corporation convertible into Series A
        Preferred Stock.

                  Section 2.  Dividends and Distributions.

                  (A)  Subject to the rights of the holders of any shares of
             any series of Preferred Stock (or any similar stock) ranking
             prior and superior to the Series A Preferred Stock with respect
             to dividends, the holders of shares of Series A Preferred Stock,
             in preference to the holders of Common Stock, par value $.0001
             per share (the "Common Stock"), of the Corporation, and of any
             other junior stock, shall be entitled to receive, when, as and
             if declared by the Board of Directors out of funds legally
             available for the purpose, quarterly dividends payable in cash
             on the first day of March, June, September and December in each
             year (each such date being referred to herein as a "Quarterly
             Dividend Payment Date"), commencing on the first Quarterly
             Dividend Payment Date after the first issuance of a share or
             fraction of a share of Series A Preferred Stock, in an amount
             per share (rounded to the nearest cent) equal to the greater of
             (a) $1.00 or (b) subject to the provision for adjustment
             hereinafter set forth, 1,000 times the aggregate per share
             amount of all cash dividends, and 1,000 times the aggregate per
             share amount (payable in kind) of all non-cash dividends or
             other distributions, other than a dividend payable in shares of
             Common Stock or a subdivision of the outstanding shares of
             Common Stock (by reclassification or otherwise), declared on the
             Common Stock since the immediately preceding Quarterly Dividend
             Payment Date or, with respect to the first Quarterly Dividend
             Payment Date, since the first issuance of any share or fraction
             of a share of Series A Preferred Stock. In the event the
             Corporation shall at any time declare or pay any dividend on the
             Common Stock payable in shares of Common Stock, or effect a
             subdivision, combination or consolidation of the outstanding
             shares of Common Stock (by reclassification or otherwise than by
             payment of a dividend in shares of Common Stock) into a greater
             or lesser number of shares of Common Stock, then in each such
             case the amount to which holders of shares of Series A Preferred
             Stock were entitled immediately prior to such event under clause
             (b) of the preceding sentence shall be adjusted by multiplying
             such amount by a fraction, the numerator of which is the number
             of shares of Common Stock outstanding immediately after such
             event and the denominator of which is the number of shares of
             Common Stock that were outstanding immediately prior to such
             event.

                  (B)  The Corporation shall declare a dividend or
             distribution on the Series A Preferred Stock as provided in
             paragraph (A) of this Section 2 immediately after it declares a
             dividend or distribution on the Common Stock (other than a
             dividend payable in shares of Common Stock); provided that, in
             the event no dividend or distribution shall have been declared
             on the Common Stock during the period between any Quarterly
             Dividend Payment Date and the next subsequent Quarterly Dividend
             Payment Date, a dividend of $1.00 per share on the Series A
             Preferred Stock shall nevertheless be payable on such subsequent
             Quarterly Dividend Payment Date.

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

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

                  (A)  Subject to the provision for adjustment hereinafter
             set forth, each share of Series A Preferred Stock shall entitle
             the holder thereof to 1,000 votes on all matters submitted to a
             vote of the stockholders of the Corporation.  In the event the
             Corporation shall at any time declare or pay any dividend on the
             Common Stock payable in shares of Common Stock, or effect a
             subdivision, combination or consolidation of the outstanding
             shares of Common Stock (by reclassification or otherwise than by
             payment of a dividend in shares of Common Stock) into a greater
             or lesser number of shares of Common Stock, then in each such
             case the number of votes per share to which holders of shares of
             Series A Preferred Stock were entitled immediately prior to such
             event shall be adjusted by multiplying such number by a
             fraction, the numerator of which is the number of shares of
             Common Stock outstanding immediately after such event and the
             denominator of which is the number of shares of Common Stock
             that were outstanding immediately prior to such event.

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

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

        Section 4. Certain Restrictions.

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

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

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

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

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

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

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


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

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

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

                  Section 9.  Rank.  The Series A Preferred Stock shall rank,
        with respect to the payment of dividends and the distribution of
        assets, junior to all series of any other class of the Corporation's
        Preferred Stock, except to the extent that any such other series
        specifically provides that it shall rank on a parity with or junior
        to the Series A Preferred Stock.

                  Section 10.  Amendment.  The Certificate of Incorporation
        of the Corporation shall not be amended in any manner which would
        materially alter or change the powers, preferences or special rights
        of the Series A Preferred Stock so as to affect them adversely
        without the affirmative vote of the holders of at least two-thirds of
        the outstanding shares of Series A Preferred Stock, voting together
        as a single class.

                  IN WITNESS WHEREOF, this Certificate of Designations is
        executed on behalf of the Corporation by its Chairman of the Board
        and attested by its Secretary this 9th day of April, 1997.

                  AMGEN INC., a corporation organized and existing under the
        General Corporation Law of the State of Delaware (the "Corporation"),
        does hereby certify:

                  FIRST:  That a resolution was duly adopted by the Board of

        the proposed amendment is as follows:

                       NOW, THEREFORE, BE IT RESOLVED, that the first
                  paragraph of the Fourth Article of the restated Certificate

                  Stock and Seven Hundred Fifty Million (750,000,000) shares
                  shall be Common Stock, all with a par value of $.000l."

                  SECOND:  That, thereafter, pursuant to a resolution of the
        Board of Directors, the officers of the Corporation solicited the
        vote of the stockholders thereof at the Annual Meeting of
        Stockholders in favor of the amendment, and the stockholders of the
        Corporation approved the amendment by a majority of the outstanding
        stock entitled to vote thereon.

                  THIRD:  That said amendment was duly adopted in accordance
        with the provisions of Section 242 of the Delaware General
        Corporation Law.

                  FOURTH:  That the capital of said corporation shall not be

        Executive Officer, and Arthur F. Staubitz, its Secretary, on this

                                     AMGEN INC.
                        RESTATED CERTIFICATE OF INCORPORATION


             FIRST:  The name of this corporation is Amgen Inc.

             SECOND:  The address of the registered office of this
        corporation in the State of Delaware is 229 South State Street, in
        the City of Dover, County of Kent, and the name of its registered
        agent at that address is The United States Corporation Company.

             THIRD:  The purpose of this corporation is to engage in any
        lawful act or activity for which a corporation may be organized under
        the General Corporation Law of Delaware other than the banking
        business, the trust company business or the practice of a profession
        permitted to be incorporated by the Delaware Corporations Code.

             FOURTH:  This corporation is authorized to issue two (2) classes
        of stock to be designated, respectively, "Preferred Stock" and
        "Common Stock."  The total number of shares which this corporation is
        authorized to issue is Fifty-Five Million (55,000,000) shares, of
        which Five Million (5,000,000) shares shall be Preferred Stock and
        Fifty Million (50,000,000) shares shall be Common Stock, all with a
        par value of one hundredth cent ($.0001).

             The Preferred Stock may be issued from time to time in one or
        more series.  The Board of Directors is expressly authorized in the
        resolution or resolutions providing for the issue of any wholly
        unissued series of Preferred Stock, to fix, state and express the
        powers, rights, designations, preferences, qualifications,
        limitations and restrictions thereof, including, without limitation:
        the rate of dividends upon which and the times at which dividends on
        shares of such series shall be payable and the preference, if any,
        which such dividends shall have relative to dividends on shares of
        any other class or classes or any other series of stock of this
        corporation; whether such dividends shall be cumulative or
        noncumulative, and if cumulative, the date or dates from which
        dividends on shares of such series shall be cumulative; the voting
        rights, if any, to be provided for shares of such series; the rights,
        if any, which the holders of shares of such series shall have in the
        event of any voluntary or involuntary liquidation, dissolution or
        winding up of the affairs of this corporation; the rights, if any,
        which the holders of shares of such series shall have to convert such
        shares into or exchange such shares for shares of stock of this
        corporation and the terms and conditions, including price and rate of
        exchange of such conversion or exchange; the redemption (including
        sinking fund provisions), if any, for shares of such series; and such
        other powers, rights, designations, preferences, qualifications,
        limitations and restrictions as the Board of Directors may desire to
        so fix.  The Board of Directors is also expressly authorized to fix
        the number of shares constituting such series and to increase or
        decrease the number of shares of any series prior to the issue of
        shares of that series and to decrease, but not increase, the number
        of shares of any series subsequent to the issue of shares of that
        series, but not below the number of shares of such series then
        outstanding (in case the number of shares of any series shall be so
        decreased, the shares constituting such decrease shall resume the
        status which they had prior to the adoption of the resolution
        originally fixing the number of shares of such series).

             FIFTH:    (a)  The number of directors which shall constitute
        the whole Board of Directors of this corporation shall be specified
        in the bylaws of this corporation, subject to the provisions of this
        Article Fifth.

                       (b)  At the 1987 annual meeting, the Board of
        Directors shall be divided into three classes:  Class I, Class II and
        Class III, which shall be as nearly equal in number as possible.
        Each director shall serve for a term ending on the date of the third
        annual meeting of stockholders following the annual meeting at which
        the director was elected; provided, however, that each initial
        director in Class I shall hold office until the annual meeting of
        stockholders in 1988; each initial director in Class II shall hold
        office until the annual meeting of stockholders in 1989; and each
        initial director in Class III shall hold office until the annual
        meeting of stockholders in 1990.  Notwithstanding the foregoing
        provisions of this Article, each director shall serve until his
        successor is duly elected and qualified or until his death,
        resignation or removal.

                       (c) In the event of any increase or decrease in the
        authorized number of directors, the newly created or eliminated
        directorships resulting from such increase or decrease shall be
        apportioned by the Board of Directors among the three classes of
        directors so as to maintain such classes as nearly equal as possible.
        No decrease in the number of directors constituting the Board of
        Directors shall shorten the term of any incumbent director.

                       (d)  Newly created directorships resulting from any
        increase in the number of directors and any vacancies on the Board of
        Directors resulting from death, resignation, disqualification,
        removal or other cause shall be filled by the affirmative vote of a
        majority of the remaining directors then in office (and not by
        stockholders), even though less than a quorum of the Board of
        Directors.  Any director elected in accordance with the preceding
        sentence shall hold office for the remainder of the full term of the
        class of directors in which the new directorship was created or the
        vacancy occurred and until such director's successor shall have been
        elected and qualified.

             SIXTH:  A director of this corporation shall not be personally
        liable to this corporation or its stockholders for monetary damages
        for breach of fiduciary duty as a director, except for liability (i)
        for any breach of the director's duty of loyalty to this corporation
        or its stockholders, (ii) for acts or omissions not in good faith or
        which involve intentional misconduct or a knowing violation of law,
        (iii) under Section 174 of the General Corporation Law of the State
        of Delaware, or (iv) for any transaction from which the director
        derived an improper personal benefit.

             SEVENTH:  This corporation reserves the right at any time and
        from time to time to amend, alter, change, or appeal any provisions
        contained herein, and other provisions authorized by the laws of the
        State of Delaware at the time in force may be added or inserted, in
        the manner now or hereafter prescribed by law, and all rights,
        preferences, and privileges of whatsoever nature conferred upon
        stockholders, directors, or any other persons whomsoever by or
        pursuant to this Certificate of Incorporation in its present form or
        as hereafter amended are granted subject to the rights reserved in
        this Article.

             EIGHTH:  All the powers of this corporation, insofar as the same
        may be lawfully vested by this Certificate of Incorporation in the
        Board of Directors, are hereby conferred upon the Board of Directors,
        who shall have full control over the affairs of this corporation.

             In furtherance and not in limitation of the powers conferred by
        law and by this Certificate of Incorporation, the Board of Directors
        is hereby expressly authorized:

                  1.  To make, amend, repeal, or otherwise alter the Bylaws
        of this corporation, without any action on the part of the
        stockholders; provided, however, that any Bylaws made by the
        directors and any and all powers conferred by any of said Bylaws may
        be amended, altered, or repealed by the stockholders.

                  2.  To fix, determine, and vary the amount to be reserved
        or maintained for any proper purpose, and to fix the times for the
        declaration and payment of dividends.

                  3.  To transfer all or any part of the assets of this
        corporation by way of mortgage, or in trust or in pledge, to secure
        indebtedness of this corporation, without any vote or consent of
        stockholders, and to authorize and to cause to be executed
        instruments evidencing any and all such transfers.

                  4.  To sell, lease, or exchange any part less than all or
        less than substantially all of the property and assets, including
        good will and corporate franchises, of this corporation upon such
        terms and conditions as the Board of Directors may deem expedient for
        the best interests of this corporation, without any authorization,
        affirmative vote, or written consent or other action of the
        stockholders or any class thereof.

             NINTH:    (a)  Vote Required for Certain Business Combinations.

                       (1)  Higher Vote for Certain Business Combinations.
        In addition to any affirmative vote required by law or this
        Certificate of Incorporation, and except as otherwise expressly
        provided in paragraph (b) of this Article NINTH:

                       (i)  any merger or consolidation of this corporation
        or any Subsidiary (as hereinafter defined) with (a) any Interested
        Stockholder (as hereinafter defined) or (b) any other corporation
        (whether or not itself an Interested Stockholder) which is, or after
        such merger or consolidation would be, an Affiliate (as hereinafter
        defined) of an Interested Stockholder; or

                       (ii)  any sale, lease, exchange, mortgage, pledge,
        transfer or other disposition or security arrangement, investment,
        loan, advance, guarantee, agreement to purchase, agreement to pay,
        extension of credit, joint venture participation or other arrangement
        (in one transaction or a series of transactions) to, with or for the
        benefit of any Interested Stockholder or any Affiliate or Associate
        of any Interested Stockholder involving any assets, securities or

        otherwise involving an Interested Stockholder) which has the effect,
        directly or indirectly, of increasing the proportionate share of the
        outstanding shares of any class of equity or convertible securities
        of this corporation or any Subsidiary which is directly or indirectly
        owned by any Interested Stockholder or any Affiliate of any
        Interested Stockholder; or

                       (v)  the issuance or transfer by this corporation or
        any Subsidiary (in a transaction or a series of transactions) of any
        securities of this corporation or any Subsidiary to any Interested
        Stockholder or any Affiliate of any Interested Stockholder in

        or (b)(2) are met:

                  (1) Approval by Disinterested Directors.  The Business

        Disinterested Directors (as hereinafter defined).

                  (2)  Price and Procedure Requirements.  All of the

        Common Stock acquired by it (1) within the two-year period
        immediately prior to the first public announcement of the proposal of
        the Business Combination (the "Announcement Date") or (2) in the
        transaction in which it became an Interested Stockholder, whichever
        is higher; and

                            (B)  the Fair Market Value per share of Common
        Stock (1) on the Announcement Date or (2) on the date on which the
        Interested Stockholder became an Interested Stockholder (such latter
        date is referred to in this Article NINTH as the "Determination
        Date"), whichever is higher.

                       (ii)  The aggregate amount of the cash and the Fair
        Market Value as of the date of the consummation of the Business

        Voting Stock, whether or not the Interested Stockholder has
        previously acquired any shares of a particular class of Voting
        Stock):

                            (A)  (if applicable) the highest per share price

        transaction in which it became an Interested Stockholder, whichever
        is higher;

                            (B) (if applicable) the highest preferential
        amount per share to which the holders of shares of such class of
        Voting Stock are entitled in the event of any voluntary or
        involuntary liquidation, dissolution or winding up of this
        corporation; and
                            (C) the Fair Market Value per share of such class
        of Voting Stock on the Announcement Date or on the Determination
        Date, whichever is higher.

        any particular class of outstanding Voting Stock (including Common
        Stock) shall be in cash or in the same form as the Interested
        Stockholder has previously paid for shares of such class of Voting
        Stock.  If the Interested Stockholder has paid for shares of any
        class of Voting Stock with varying forms of consideration, the form
        of consideration for such class of Voting Stock shall be either cash
        or the form used to acquire the largest number of shares of such
        class of Voting Stock previously acquired by it.  The price
        determined in accordance with subparagraphs (b)(2)(i) and (b)(2)(ii)
        shall be subject to appropriate adjustment in the event of any stock
        dividend, stock split, combination of shares or similar event.

                       (iv)  A proxy or information statement describing the
        proposed Business Combination and complying with the requirements of
        the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
        and the rules and regulations thereunder (or any subsequent
        provisions replacing the Exchange Act or such rules or regulations)
        shall be mailed to public stockholders of this corporation at least
        thirty (30) days prior to the consummation of such Business
        Combination (whether or not such proxy or information statement is
        required to be mailed pursuant to such Act or subsequent provisions).

                       (v)  After such Interested Stockholder has become an
        Interested Stockholder and prior to the consummation of such Business
        Combination:

                            (A)  except as approved by a majority of the
        Board entitled to vote thereon (determined in a manner similar to
        that set forth in subparagraph (b)(1) above), there shall have been
        no failure to declare and pay at the regular date therefor any full
        quarterly dividends (whether or not cumulative) on the outstanding
        Preferred Stock;

                            (B)  there shall have been (I) no reduction in
        the annual rate of dividends paid on the Common Stock (except as
        necessary to reflect any subdivision of the Common Stock), except as
        approved by a majority of the Board entitled to vote thereon
        (determined in a manner similar to that set forth in subparagraph
        (b)(1) above), and (II) an increase in such annual rate of dividends
        as necessary to reflect any reclassification (including any reverse
        stock split), recapitalization, reorganization or any similar
        transaction which has the effect of reducing the number of
        outstanding shares of the Common Stock, unless the failure so to
        increase such annual rate is approved by a majority of the Board
        entitled to vote thereon (determined in a manner similar to that set
        forth in subparagraph (b)(1) above); and

                            (C)  such Interested Stockholder shall have not
        become the beneficial owner of any additional shares of Voting Stock
        except as part of the transaction which results in such Interested
        Stockholder becoming an Interested Stockholder.
                       (vi)  After such Interested Stockholder has become an
        Interested Stockholder, such Interested Stockholder shall not have
        received the benefit, directly or indirectly (except proportionately
        as a stockholder), of any loans, advances, guarantees, pledges or
        other financial assistance or any tax credits or other tax advantages
        provided by this corporation, whether in anticipation of or in
        connection with such Business Combination or otherwise.

             (c)  Certain Definitions.  For the purposes of this Article
        NINTH:

                  (1)  A "person" shall mean any individual, firm,
        corporation or other entity.

                  (2)  "Interested Stockholder" shall mean any person (other
        than this corporation or any Subsidiary) who or which:

                       (i)  is the beneficial owner, directly or indirectly,
        of more than twenty percent (20%) of the voting power of the
        outstanding Voting Stock; or

                       (ii)  is an Affiliate of this corporation and at any
        time within the two-year period immediately prior to the date in
        question was the beneficial owner, directly or indirectly, of twenty
        percent (20%) or more of the voting power of the then outstanding
        Voting Stock; or

                       (iii)  is an assignee of or has otherwise succeeded to
        any shares of Voting Stock that were at any time within the two-year
        period immediately prior to the date in question beneficially owned
        by an Interested Stockholder, if such assignment or succession shall
        have occurred in the course of a transaction or series of
        transactions not involving a public offering within the meaning of
        the Securities Act of 1933, as amended.

                  (3)  A person shall be a "beneficial owner" of any Voting
        Stock:

                       (i)  that such person or any of its Affiliates or
        Associates (as hereinafter defined) beneficially owns, directly or
        indirectly; or

                       (ii)  that such person or any of its Affiliates or
        Associates has:

                            (A)  the right to acquire (whether such right is
        exercisable immediately or only after the passage of time), pursuant
        to an agreement, arrangement or understanding or upon the exercise of
        conversion rights, exchange rights, warrants or options, or
        otherwise; provided, however, that a person shall not be deemed the
        beneficial owner of securities tendered pursuant to a tender or
        exchange offer made by or on behalf of such person or any of such
        persons' Affiliates or Associates until such tendered securities are
        accepted for purchase; or

                            (B)  the right to vote pursuant to any agreement,
        arrangement or understanding; provided, however, that a person shall
        not be deemed the beneficial owner of any security if the agreement,
        arrangement or understanding to vote such security (I) arises solely
        from a revocable proxy or consent given to such person in response to
        a public proxy or consent solicitation made pursuant to, and in
        accordance with, the Exchange Act and (II) is not also then
        reportable on Schedule 13D under the Exchange Act (or a comparable or
        successor report); or

                       (iii)  that is beneficially owned, directly or
        indirectly, by any other person with which such person or any of its
        Affiliates or Associates has any agreement, arrangement or
        understanding for the purpose of acquiring, holding, voting (except
        to the extent permitted by the proviso of subparagraph (c)(3)(ii)(B)
        above) or disposing of any shares of Voting Stock.

                  (4)  For the purposes of determining whether a person is an
        Interested Stockholder pursuant to subparagraph (c)(2), the number of
        shares of Voting Stock deemed to be outstanding shall include shares
        deemed owned through application of subparagraph (c)(3), but shall
        not include any other shares of Voting Stock that may be issuable
        pursuant to any agreement, arrangement or understanding, or upon
        exercise of conversion rights, warrants or options, or otherwise.

                  (5)  "Affiliate" or "Associate" shall have the respective
        meanings ascribed to such terms in Rule 12b-2 of the General Rules
        and Regulations under the Exchange Act, as in effect on January 1,
        1988.

                  (6)  "Subsidiary" means any corporation of which a majority
        of any class of equity security is owned, directly or indirectly, by
        this corporation; provided, however, that for the purposes of the
        definition of Interested Stockholder set forth in subparagraph
        (c)(2), the term "Subsidiary" shall mean only a corporation of which
        a majority of each class of equity security is owned, directly or
        indirectly, by this corporation.

                  (7)  "Disinterested Director" means any member of the Board
        of Directors of this corporation (the "Board") who is unaffiliated
        with the Interested Stockholder and was a member of the Board prior
        to the time that the Interested Stockholder became an Interested
        Stockholder, and any successor of a Disinterested Director who is
        unaffiliated with the Interested Stockholder and is recommended to
        succeed a Disinterested Director by a majority of Disinterested
        Directors then on the Board.

                  (8)  "Majority of the Disinterested Directors" means a
        majority of the Disinterested Directors, whether or not the number of
        such Disinterested Directors then constitutes a quorum of the Board
        of Directors of this corporation.

                  (9)  "Fair Market Value" means:

                       (i)  in the case of stock, the average of the closing
        sale prices during the ten (10)-day period immediately preceding the
        date in question of a share of such stock on the Composite Tape for
        New York Stock Exchange-Listed Stocks, or, if such stock is not
        quoted on the Composite Tape, on the New York Stock Exchange, or, if
        such stock is not listed on such exchange, on the principal United
        States securities exchange registered under the Exchange Act on which
        such stock is listed, or, if the stock is not listed on any such
        exchange but is listed as a National Market System stock in the
        National Association of Securities Dealers, Inc. Automated Quotation
        System, as reported in that National Market System, if such stock is
        not listed on any such exchange or reported in such system the
        average of the closing bid quotations with respect to a share of such
        stock during the ten (10)-day period preceding the date in question
        on the National Association of Securities Dealers, Inc. Automated
        Quotations System or any system then in use, or if no such quotations
        are available, the fair market value on the date in question of a
        share of such stock as determined by the Board in good faith; and

                       (ii)  in the case of property other than cash or
        stock, the fair market value of such property on the date in question
        as determined by the Board in good faith.

                  (10)  In the event of any Business Combination in which the
        corporation survives, the phrase "consideration other than cash to be
        received" as used in subparagraphs (b)(2)(i) and (ii) of this Article
        NINTH shall include the shares of Common Stock and/or the shares of
        any other class of outstanding Voting Stock retained by the holders
        of such shares.

             (d)  Powers of the Board of Directors.  A majority of the
        Disinterested Directors of this corporation shall have the power and
        duty to determine for the purposes of this Article NINTH on the basis
        of information known to them after reasonable inquiry:

                  (i)  whether a person is an Interested Stockholder;

                  (ii)  the number of shares of Voting Stock beneficially
        owned by any person;

                  (iii)  whether a person is an Affiliate or Associate of
        another; and

                  (iv)  the Fair Market Value of the assets that are the
        subject of any Business Combination. A majority of the Disinterested
        Directors of this corporation shall have the further power to
        interpret all of the terms and provisions of the Article NINTH.  Any
        such determination made in good faith shall be binding and conclusive
        on all parties.

             (e)  No Effect on Fiduciary Obligations of Interested
        Stockholders or Directors.

                  (1)  Nothing contained in this Article Ninth shall be
        construed to relieve any Interested Stockholder from any fiduciary
        obligation imposed by law.

                  (2)  The fact that any Business Combination complies with
        the provisions of Section (b) of this Article NINTH shall not be
        construed to impose any fiduciary duty, obligation or responsibility
        on the Board of Directors, or any member thereof, to approve such
        Business Combination or recommend its adoption or approval to the
        stockholders of the corporation, and such compliance shall not limit,
        prohibit or otherwise restrict in any manner the Board of Directors,
        or any members thereof, with respect to evaluations of or actions and
        responses taken with respect to such Business Combination.

             (f)  Amendment, Repeal, etc.  Notwithstanding any other
        provisions of this Certificate of Incorporation or the bylaws of this
        corporation (and notwithstanding the fact that a lesser percentage
        may be specified by law, this Certificate of Incorporation or the
        bylaws of this corporation), the affirmative vote of the holders of
        sixty-six and two-thirds percent (66-2/3%) or more of the outstanding
        Voting Stock not then held by any Interested Stockholder, voting
        together as a single class, shall be required to amend or repeal, or
        adopt any provisions inconsistent with this Article NINTH.

             TENTH:  Any action required or permitted to be taken by the
        stockholders of this corporation must be effected at a duly called
        annual or special meeting of such holders and may not be effected by
        any consent in writing by such holders.  At any annual meeting or
        special meeting of stockholders of this corporation, only such
        business shall be conducted as shall have been brought before such
        meeting in the manner provided by the bylaws of this corporation.
