                            DATED: SEPTEMBER 28, 2004

      The undersigned corporation certifies that it has adopted the following
restated certificate of incorporation:

      FIRST: The name of the Corporation is Schering-Plough Corporation.

      SECOND: The Corporation is organized to engage in any activity within the
purposes for which a corporation may be organized under the New Jersey Business
Corporation Act.

      THIRD: The aggregate number of shares which the Corporation shall have
authority to issue shall be two billion four hundred fifty million
(2,450,000,000) shares to consist of:

      (a)   Two billion four hundred million (2,400,000,000) Common Shares of
            the par value of Fifty Cents ($0.50) per share, and

      (b)   Fifty million (50,000,000) Preferred Shares of the par value of One
            Dollar ($1.00) per share issuable in series to consist of:

            (1) Twelve million (12,000,000) Preferred Shares designated "Series
      A Junior Participating Preferred Stock,"

            (2) Twenty-eight million seven hundred fifty thousand (28,750,000)
      Preferred Shares designated "6.00% Mandatory Convertible Preferred Stock,"
      and

            (3) Nine million two hundred fifty thousand (9,250,000) Preferred
      Shares whose designations have not yet been determined.

      FOURTH: The relative rights, preferences and limitations of each class and
series are as follows:

      (a)   Common Shares.

            (1) Voting Rights. Each holder of record of Common Shares shall be
      entitled to one vote in person or by proxy for each share standing in his
      name on the books of the Corporation.

            (2) Dividends. Dividends may be paid on the Common Shares when and
      as declared by the Board of Directors after payment has been made, or
      funds have been set aside for payment, of all dividends, sinking funds,
      retirement funds or other retirement benefits to which the holders of
      Preferred Shares are entitled.



            (3) Liquidation. In the event of any liquidation or dissolution,
      after the full preferential amounts to which the holders of Preferred
      Shares and any other class having preference over the Common Shares have
      been paid or set aside, the holders of the Common Shares shall be entitled
      to receive the remaining assets of the Corporation available for
      distribution.

      (b)   Preferred Shares.

            (1) Issuance. The Board of Directors may issue the Preferred Shares
      in series and fix the voting powers, designations, preferences, rights,
      qualifications, limitations and restrictions of each such series to the
      extent not fixed or limited by the provisions set forth herein (and
      subject to limitations prescribed by law).

            (2) Voting. Whenever accrued dividends on the Preferred Shares in an
      amount equivalent to six quarterly dividends shall not have been paid or
      declared and a sum sufficient for the payment thereof set aside, the
      holders of the Preferred Shares, voting separately as a class, shall be
      entitled to elect two directors at the next annual or special meeting of
      the shareholders. Such right of the holders of the Preferred Shares to
      elect two directors may be exercised until dividends in default on the
      Preferred Stock shall have been paid in full or declared and a sum
      sufficient for the payment thereof set aside. When so paid or provided
      for, the right of the holders of the Preferred Shares to elect such number
      of directors shall cease, but subject always to the same provisions for
      the vesting of such voting rights in the case of any such future dividend
      default or defaults. During any time that the holders of the Preferred
      Shares, voting as a class, are entitled to elect two directors as
      hereinabove provided, the holders of any series of Preferred Shares
      entitled to participate with the holders of the Common Shares in the
      election of directors shall not be so entitled to participate with the
      holders of the Common Shares in the election of such directors.

            At any annual or special meeting of the shareholders or any
      adjournment thereof at which the holders of Preferred Shares shall be
      entitled to elect two directors, if the holders of at least a majority of
      the Preferred Shares then outstanding shall be present or represented by
      proxy, then, by vote of the holders of at least a majority of the
      Preferred Shares then present or so represented at such meeting, the
      authorized number of directors of the Corporation shall be increased by
      two, and at such meeting, the holders of the Preferred Shares, voting as a
      class, shall be entitled to elect the additional directors so provided
      for. Whenever the holders of Preferred Shares shall be divested of special
      voting power as herein provided, the terms of all persons elected as
      directors by the holders of the Preferred Shares as a class shall
      terminate at the next annual meeting, and the authorized number of
      directors of the Corporation shall be reduced accordingly.

      (c)   Series A Junior Participating Preferred Stock.

      Pursuant to the authority conferred by this Article Fourth, the following
series of Preferred Shares has been designated with such series consisting of

      NINTH: Board of Directors

      (a)   Number, Election and Terms. The business and affairs of the
            Corporation shall be managed by a Board of Directors which, subject
            to any rights of the holders of any series of Preferred Shares of
            the Corporation ("Preferred Shares") then outstanding to elect
            additional directors under specified circumstances, shall consist of
            not less than nine (9) nor more than twenty-one (21) persons. The
            exact number of directors within the minimum and maximum limitations
            specified in the preceding sentence shall be fixed from time to time
            by either (i) the Board of Directors pursuant to a resolution
            adopted by a majority of the entire Board of Directors or (ii) the
            affirmative vote of the holders of at least 80% of the voting power
            of all of the shares of the Corporation entitled to vote generally
            in the election of directors, voting together as a single class. No
            decrease in the number of directors constituting the Board of
            Directors shall shorten the term of any incumbent director. At the
            1985 annual meeting of shareholders, the directors shall be divided
            into three classes, as nearly equal in number as possible (but with
            not less than three directors in each class), with the term of
            office of the first class to expire at the 1986 annual meeting of
            shareholders, the term of office of the second class to expire at
            the 1987 annual meeting of shareholders and the term of office of
            the third class to expire at the 1988 annual meeting of
            shareholders, and with the members of each class to hold office
            until their successors shall have been elected and qualified. At
            each annual meeting of shareholders following such initial
            classification and election, directors elected to succeed those
            directors whose terms expire shall be elected for a term of office
            to expire at the third succeeding annual meeting of shareholders
            after their election.

      (b)   Shareholder Nomination of Director Candidates. Advance notice of
            shareholder nominations for the election of directors shall be given
            in the manner provided in the By-laws.

      (c)   Newly Created Directorships and Vacancies. Subject to the rights of
            the holders of any series of Preferred Shares then outstanding,
            newly created directorships

                                       -4-


            resulting from any increase in the authorized number of directors
            and any vacancies in the Board of Directors resulting from death,
            resignation, retirement, disqualification, removal from office or
            other cause may be filled by a majority vote of the directors then
            in office even though less than a quorum, or by a sole remaining
            director.

      (d)   Removal. Subject to the rights of the holders of any series of
            Preferred Shares then outstanding, any director, or the entire Board
            of Directors, may be removed from office at any time only for cause
            and only by the affirmative vote of the holders of at least 80% of
            the voting power of all of the shares of the Corporation entitled to
            vote generally in the election of directors, voting together as a
            single class.

      (e)   Amendment, Repeal, etc. Notwithstanding anything contained in this
            Certificate of Incorporation to the contrary, the affirmative vote
            of the holders of at least 80% of the voting power of all of the
            shares of the Corporation entitled to vote generally in the election
            of directors, voting together as a single class, shall be required
            to alter, amend, adopt any provision inconsistent with or repeal
            this Article Ninth entitled "Board of Directors", or to alter,
            amend, adopt any provision inconsistent with or repeal Sections 1
            ("Number, Election and Terms"), 2 ("Removal") or 3 ("Newly Created
            Directorships and Vacancies") of Article V ("Directors"), Article VI
            ("Nominations of Director Candidates") or Article IX ("Amendment,
            Repeal, etc.") of the By-laws of the Corporation.

      TENTH: Shareholder Action

            Subject to the rights of the holders of any series of Preferred
Shares then outstanding, any action required or permitted to be taken by the
shareholders of the Corporation must be effected at a duly called annual or
special meeting of shareholders of the Corporation and may not be effected by
any consent in writing by such shareholders unless all of the shareholders
entitled to vote thereon consent thereto in writing. Notwithstanding anything
contained in this Certificate of Incorporation to the contrary, the affirmative
vote of the holders of at least 80% of the voting power of all of the shares of
the Corporation entitled to vote generally in the election of directors, voting
together as a single class, shall be required to alter, amend, adopt any
provision inconsistent with or repeal this Article entitled "Shareholder
Action", or to alter, amend, adopt any provision inconsistent with or repeal
Article IV ("Shareholder Action") of the By-laws of the Corporation.

      ELEVENTH: Business Combinations

      (a)   Vote Required for Business Combinations.

            (1) Higher Vote for Business Combinations. In addition to any
      affirmative vote required by law or this Certificate of Incorporation, and
      except as otherwise expressly provided in Section (b) of this Article
      Eleventh, any Business Combination (as hereinafter defined) shall require
      the affirmative vote of the holders of at least 80% of the voting power of
      all of the then outstanding shares of capital stock of the Corporation

                                       -5-


      entitled to vote generally in the election of directors (the "Voting
      Stock"), voting together as a single class (it being understood that, for
      purposes of this Article Eleventh, each share of the Voting Stock shall
      have the number of votes granted to it pursuant to Article Fourth of this
      Certificate of Incorporation). Such affirmative vote shall be required
      notwithstanding the fact that no vote may be required, or that a lesser
      percentage may be specified, by law or in any agreement with any national
      securities exchange or otherwise.

            (2) Definition of "Business Combination". The term "Business
      Combination" as used in this Article Eleventh shall mean any transaction
      which is referred to in any one or more of the following clauses (A)
      through (E):

                  (A) any merger or consolidation of the Corporation or any
      Subsidiary (as hereinafter defined) with (i) any Interested Shareholder
      (as hereinafter defined) or (ii) any other corporation (whether or not
      itself an Interested Shareholder) which is, or after such merger or
      consolidation would be, an Affiliate (as hereinafter defined) of an
      Interested Shareholder; or

                  (B) any sale, lease, exchange, mortgage, pledge, transfer or
      other disposition (in one transaction or a series of transactions) to or
      with any Interested Shareholder or any Affiliate of any Interested
      Shareholder of any assets of the Corporation or any Subsidiary having an
      aggregate Fair Market Value (as hereinafter defined) of $50,000,000 or
      more; or

                  (C) the issuance or transfer by the Corporation or any
      Subsidiary (in one transaction or a series of transactions) of any
      securities of the Corporation or any Subsidiary having an aggregate Fair
      Market Value of $50,000,000 or more to any Interested Shareholder or any
      Affiliate of any Interested Shareholder; or

                  (D) the adoption of any plan or proposal for the liquidation
      or dissolution of the Corporation proposed by or on behalf of an
      Interested Shareholder or any Affiliate of any Interested Shareholder; or

                  (E) any reclassification of securities (including any reverse
      stock split), or recapitalization of the Corporation, or any merger or
      consolidation of the Corporation with any of its Subsidiaries or any other
      transaction (whether or not with or into or otherwise involving an
      Interested Shareholder) 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 the Corporation or any Subsidiary
      which is directly or indirectly owned by any Interested Shareholder or any
      Affiliate of any Interested Shareholder.

      (b)   When Higher Vote is Not Required. The provisions of Section (a) of
            this Article Eleventh shall not be applicable to any particular
            Business Combination, and such Business Combination shall require
            only such affirmative vote as is required by law and any other
            provision of this Certificate of Incorporation, if all of the
            conditions specified in either of the following paragraphs (1) or
            (2) are met:

      have been approved by a majority of the total number of the Continuing

      the following conditions shall have been met:

            public announcement of the proposal of the Business Combination (the
            "Announcement Date") or in the transaction in which it became an
            Interested Shareholder, whichever is higher, or (y) the Fair Market
            Value per share of Common Shares on the day after the Announcement
            Date or on the date on which the Interested Shareholder became an

            of record on record dates occurring in the interim, up to the amount
            of such interest.

      is one in which the Corporation is to become the surviving entity and such
      class of outstanding Voting Stock is to remain outstanding without any
      change in its rights, preferences and limitations, in which case such
      aggregate amount shall be at least equal to the sum of (x) the higher of
      the amounts set forth in subparagraphs (i)(x) and (i)(z) below and (y) the

      previously acquired any shares of a particular class of Voting Stock]:

            were acquired within the two-year period immediately prior to the
            Announcement Date or in the transaction in which it became an
            Interested Shareholder, whichever is higher, (y) (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
            the Corporation, or (z) the Fair Market Value per share of such
            class of Voting Stock on the day after the Announcement Date or on
            the Determination Date, whichever is higher; and

      (ii)  interest on the per share price calculated at the rate of 90-day
            United States Treasury obligations in effect on the Determination
            Date, compounded annually from that date until the Consummation
            Date, less the per share amount of cash dividends payable on such
            class to holders of record on record dates occurring in the interim,
            up to the amount of such interest.

                  (C) The consideration to be received by holders of a
      particular class of outstanding Voting Stock (including Common Shares)
      shall be in cash or in the same form as the Interested Shareholder has
      previously paid for shares of such class of Voting Stock. If the
      Interested Shareholder 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.

                  (D) The holders of all outstanding shares of Voting Stock not
      beneficially owned by the Interested Shareholder immediately prior to the
      consummation of any Business Combination shall be entitled to receive in
      such Business Combination cash or other consideration for their shares
      meeting all of the terms and conditions of this paragraph (2) (provided,
      however, that the failure of any shareholders who are exercising their
      statutory rights to dissent from such Business Combination and receive
      payment of the fair value of their shares to exchange their shares in such
      Business Combination shall not be deemed to have prevented the condition
      set forth in this subparagraph (2)(D) from being satisfied).

                  (E) After such Interested Shareholder has become an Interested
      Shareholder and prior to the consummation of such Business Combination:
      (i) except as approved by a majority of the total number of Continuing
      Directors, 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 Shares of the Corporation; (ii)
      there shall have been (x) no reduction in the annual rate of dividends
      paid on the Common Shares (except as necessary to reflect any subdivision
      of the Common Shares), except as approved by a majority of the total
      number of Continuing Directors, and (y) 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
      Common Shares,

                                       -8-


      unless the failure so to increase such annual rate is approved by a
      majority of the total number of Continuing Directors; and (iii) such
      Interested Shareholder shall not have become the beneficial owner of any
      additional shares of Voting Stock except as part of the transaction which
      results in such Interested Shareholder becoming an Interested Shareholder.

                  (F) After such Interested Shareholder has become an Interested
      Shareholder, such interested Shareholder shall not have received the
      benefit, directly or indirectly (except proportionately as a shareholder),
      of any loans, advances, guarantees, pledges or other financial assistance
      or any tax credits or other tax advantages provided by the Corporation,
      whether in anticipation of or in connection with such Business Combination
      or otherwise.

                  (G) A proxy or information statement describing the proposed
      Business Combination and complying with the requirements of the Securities
      Exchange Act of 1934 and the rules and regulations thereunder (or any
      subsequent provisions replacing such Act, rules or regulations) shall be
      mailed to public shareholders of the Corporation at least 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). Such proxy or information statement shall contain,
      if a majority of the total number of Continuing Directors so requests, an
      opinion of a reputable investment banking firm (which firm shall be
      selected by a majority of the total number of Continuing Directors,
      furnished with all information it reasonably requests, and paid a
      reasonable fee for its services by the Corporation upon the Corporation's
      receipt of such opinion) as to the fairness (or lack of fairness) of the
      terms of the proposed Business Combination from the point of view of the
      holders of shares of Voting Stock (other than the Interested Shareholder).

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

      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.

      Associates has any agreement, arrangement or understanding for the purpose
      of acquiring, holding, voting or disposing of any shares of Voting Stock.

            (4) In determining whether a person is an Interested Shareholder
      pursuant to paragraph (2) of this Section (c), the number of shares of
      Voting Stock deemed to be outstanding shall include shares deemed owned

      term "Subsidiary" shall mean only a corporation of which a majority of
      each class of equity security is owned, directly or indirectly, by the
      Corporation.

      any successor of a Continuing Director who is unaffiliated with the
      Interested Shareholder and who is recommended to succeed a Continuing
      Director by a majority of the total number of Continuing Directors then on
      the Board of Directors.

            (8) "Fair Market Value" shall mean: (A) in the case of stock, the
      highest closing sale price during the 30-day period immediately preceding

      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 Securities Exchange Act of 1934 on which

      appropriately adjusted for any dividend or distribution in shares of such
      stock or any stock split or reclassification of outstanding shares of such

      reclassification of outstanding shares of such stock into a smaller number
      of shares of such stock; and (B) 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 a majority of the total number of Continuing Directors in

      received" as used in paragraphs (2)(A) and (2)(B) of Section (b) of this
      Article Eleventh shall include the Common Shares and/or the shares of any
      other class of outstanding Voting Stock retained by the holders of such

            the basis of information known to them after reasonable inquiry,
            whether a person is an Interested Shareholder. Once the Board of
            Directors has made a determination, pursuant to the preceding
            sentence, that a person is an Interested Shareholder, a majority of
            the total number of Directors of the Corporation who would qualify
            as Continuing Directors shall have the power and duty to interpret
            all of the terms and provisions of this Article Eleventh, and to

            Combination has, an aggregate Fair Market Value of $50,000,000 or
            more, and (4) whether all

                                      -11-


            of the applicable conditions set forth in paragraph (2) of Section
            (b) of this Article Eleventh have been met with respect to any
            Business Combination. Any determination pursuant to this Section (d)
            made in good faith shall be binding and conclusive on all parties.

      (e)   No Effect on Fiduciary Obligations of Interested Shareholders.
            Nothing contained in this Article Eleventh shall be construed to
            relieve any Interested Shareholder from any fiduciary obligation
            imposed by law.

      (f)   Amendment, Repeal, etc. Notwithstanding any other provisions of this
            Certificate of Incorporation or the By-laws of the Corporation (and

            Corporation), and in addition to any affirmative vote of the holders
            of Preferred Shares or any other class of capital stock of the

            the voting power of all the shares of the then outstanding Voting
            Stock, voting together as a single class, shall be required to amend
            or repeal, or adopt any provision inconsistent with, this Article
            Eleventh of this Certificate of Incorporation.

      plan or other enterprise (whether or not for profit), serving as such at
      the request of the Corporation or of any such constituent corporation, or
      the legal representative of any such director, officer, trustee, employee
      or agent, shall be indemnified and held harmless by the Corporation to the
      fullest extent permitted by the New Jersey Business Corporation Act, as
      the same exists or may hereafter be amended (but, in the case of any such
      amendment, only to the extent that such amendment permits the Corporation
      to provide broader indemnification rights than said Act permitted prior to
      such amendment), from and against any and all reasonable costs,
      disbursements and attorneys' fees, and any and all amounts paid or
      incurred in satisfaction of settlements, judgments, fines and penalties,
      incurred or suffered in connection with any such proceeding, and such
      indemnification shall continue as to a person who has ceased to be a
      director, officer, trustee, employee or agent and shall inure to the
      benefit of his or her heirs, executors, administrators and assigns;
      provided, however, that, except as provided in paragraph (2) of this
      Section (b), the Corporation shall indemnify any such person seeking
      indemnification in connection with a proceeding (or part thereof)
      initiated by such person only if such proceeding (or part thereof) was
      specifically authorized by the Board of Directors of the Corporation. The
      right to indemnification conferred in this Section shall be a contract
      right and shall include the right to be paid by the Corporation the
      expenses incurred in connection with any proceeding in advance of the
      final disposition of such proceeding as authorized by the Board of
      Directors; provided, however, that, if the New Jersey Business Corporation
      Act so requires, the payment of such expenses in advance of the final
      disposition of a proceeding shall be made only upon receipt by the
      Corporation of an undertaking, by or on behalf of such director, officer,
      employee, or agent to repay all amounts so advanced unless it shall
      ultimately be determined that such person is entitled to be indemnified
      under this Section or otherwise.

            (2) Right of Claimant to Bring Suit. If a claim under paragraph (1)
      of this Section (b) is not paid in full by the Corporation within thirty
      days after a written request

                                      -15-


      has been received by the Corporation, the claimant may at any time
      thereafter apply to a court for an award of indemnification by the
      Corporation for the unpaid amount of the claim and, if successful on the
      merits or otherwise in connection with any proceeding, or in the defense
      of any claim, issue or matter therein, the claimant shall be entitled also
      to be paid by the Corporation any and all expenses incurred or suffered in
      connection with such proceeding. It shall be a defense to any such action
      (other than an action brought to enforce a claim for the advancement of
      expenses incurred in connection with any proceeding where the required
      undertaking, if any, has been tendered to the Corporation) that the
      claimant has not met the standard of conduct which makes it permissible
      under the New Jersey Business Corporation Act for the Corporation to
      indemnify the claimant for the amount claimed, but the burden of proving
      such defense shall be on the Corporation. Neither the failure of the
      Corporation (including its Board of Directors, independent legal counsel
      or its shareholders) to have made a determination prior to the
      commencement of such proceeding that indemnification of the claimant is
      proper in the circumstances because he or she has met the applicable
      standard of conduct set forth in the New Jersey Business Corporation Act,
      nor an actual determination by the Corporation (including its Board of
      Directors, independent legal counsel or its shareholders) that the
      claimant has not met such applicable standard of conduct, nor the
      termination of any proceeding by judgment, order, settlement, conviction
      or upon a plea of nolo contendere or its equivalent, shall be a defense to
      the action or create a presumption that the claimant has not met the
      applicable standard of conduct.

            (3) Non-Exclusivity of Rights. The right to indemnification and
      advancement of expenses provided by or granted pursuant to this Section
      (b) shall not exclude or be exclusive of any other rights to which any
      person may be entitled under a certificate of incorporation, by-law,
      agreement, vote of shareholders or otherwise, provided that no
      indemnification shall be made to or on behalf of such person if a judgment
      or other final adjudication adverse to such person establishes that such
      person has not met the applicable standard of conduct required to be met
      under the New Jersey Business Corporation Act.

            (4) Insurance. The Corporation may purchase and maintain insurance
      on behalf of any director, officer, employee or agent of the Corporation
      or another corporation, partnership, joint venture, trust, employee
      benefit plan or other enterprise against any expenses incurred in any
      proceeding and any liabilities asserted against him or her by reason of
      such person's being or having been such a director, officer, employee or
      agent, whether or not the Corporation would have the power to indemnify
      such person against such expenses and liabilities under the provisions of
      this Section (b) or otherwise.

                                      -16-


            IN WITNESS WHEREOF, the undersigned corporation has caused this
certificate to be executed on its behalf by its duly authorized officer as of
the date first above written.

                                      SCHERING-PLOUGH CORPORATION

                                      By: /s/ Susan Ellen Wolf
                                          Secretary, Associate General Counsel
                                          and Staff Vice President

                                      -17-


                                     ANNEX A

                  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

      (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 12,000,000. 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.

      (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 $.50 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 or (b) subject to the provision for adjustment hereinafter set forth,
100 times the aggregate per share amount of all cash dividends, and 100 times
the aggregate per share amount (payable in kind) of all non-cash dividends or
other distributions, other than a dividend payable in shares of Common Stock or
a subdivision of the outstanding shares of Common Stock (by reclassification or
otherwise), declared on the Common Stock since the immediately preceding
Quarterly Dividend Payment Date or, with respect to the first Quarterly Dividend
Payment Date, since the first issuance of any share or fraction of a share of
Series A Preferred Stock. In the event the Corporation shall at any time declare
or pay any dividend on the Common Stock payable in shares of Common Stock, or
effect a subdivision or combination or consolidation of the outstanding shares
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
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

                                       A-1


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
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.

      (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 100
votes on all matters submitted to a vote of the stockholders of the Corporation.
In the event the Corporation shall at any time declare or pay any dividend on
the Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the number of votes per share to which holders of shares of Series 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
Amendment 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 or
the Certificate of Incorporation, 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.

                                       A-2


      (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.

      (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 Amendment creating a series of
Preferred Stock or any similar stock or as otherwise required by law.

                                       A-3


      (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 $100 per share, plus an amount equal to accrued and unpaid dividends
and distributions thereon, whether or not declared, to the date of such payment,
provided that the holders of shares of Series A Preferred Stock shall be
entitled to receive an aggregate amount per share, subject to the provision for
adjustment hereinafter set forth, equal to 100 times the aggregate amount to be
distributed per share to holders of shares of Common Stock, or (2) to the
holders of shares of stock ranking on a parity (either as to dividends or upon
liquidation, dissolution or winding up) with the Series A Preferred Stock,
except distributions made ratably on the Series A Preferred Stock and all such
parity stock in proportion to the total amounts to which the holders of all such
shares are entitled upon such liquidation, dissolution or winding up. In the
event the Corporation shall at any time declare or pay any dividend on the
Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) 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 were outstanding immediately prior to such
event.

      (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 100 times the aggregate amount of stock, securities, cash and/or any
other property (payable in kind), as the case may be, into which or for which
each share of Common Stock is changed or exchanged. In the event the Corporation
shall at any time declare or pay any dividend on the Common Stock payable in
shares of Common Stock, or effect a subdivision or combination or consolidation
of the outstanding shares of Common Stock (by reclassification or otherwise than
by payment of a dividend in shares of Common Stock) into a greater or lesser
number of shares of Common Stock, then in each such case the amount set forth in
the preceding sentence with respect to the exchange or change of shares of
Series 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.

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

      (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.

                                       A-4


      (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.

                                       A-5



                                     ANNEX B

                   6.00% MANDATORY CONVERTIBLE PREFERRED STOCK

      (1)   Designation and Amount. This series of Preferred Shares shall be
designated as "6.00% Mandatory Convertible Preferred Stock" (the "CONVERTIBLE
PREFERRED STOCK") and the number of shares constituting such series shall be
28,750,000, with a par value of $1.00 per share.

      (2)   Ranking. The Convertible Preferred Stock shall rank, as to payment
of dividends and distribution of assets upon dissolution, liquidation or winding
up of the Corporation, (a) senior to (i) the Common Stock, (ii) the Series A
Preferred Stock and (iii) any class or series of capital stock issued by the
Corporation which by its terms ranks junior to the Convertible Preferred Stock
(collectively, the "JUNIOR SECURITIES"), (b) junior to any class or series of
capital stock issued by the Corporation which by its terms ranks senior to the
Convertible Preferred Stock (the "SENIOR SECURITIES"), and (c) pari passu with
any other class or series of capital stock issued by the Corporation (the
"PARITY SECURITIES"), in each case, whether now outstanding or to be issued in
the future.

      (3)   Dividends. (a) Dividends on the Convertible Preferred Stock will be
payable quarterly when, as and if declared by the Board, or a duly authorized
committee thereof, when the Corporation is legally permitted to do so, on each
Dividend Payment Date, at the annual rate of $3.00 per share, subject to
adjustment as provided for in Section 18(c). The initial dividend on the
Convertible Preferred Stock for the first Dividend Period, commencing on the
date of first issuance of the Convertible Preferred Stock (assuming a date of
first issuance of August 10, 2004), to but excluding December 15, 2004, will be
$1.0417 per share, and when, as and if declared, will be payable on December 15,
2004, provided that the Corporation is legally permitted to pay such dividends
at such time. Each subsequent quarterly dividend on the Convertible Preferred
Stock, when, as and if declared, will be $0.75 per share, subject to adjustment
as provided for in Section 18(c). Dividends payable, when, as and if declared,
on a Dividend Payment Date will be payable to Record Holders for the applicable
Dividend Payment Date, except as otherwise provided in Section 6(a).

      (b)   The amount of dividends payable on each share of Convertible
Preferred Stock for each full quarterly period will be computed by dividing the
annual dividend rate by four. The amount of dividends payable for any other
period that is shorter or longer than a full quarterly dividend period will be
computed on the basis of a 360-day year consisting of twelve 30-day months.
Dividends on the Convertible Preferred Stock shall accrue and cumulate if the
Corporation fails to declare one or more dividends on the Convertible Preferred
Stock in any amount, whether or not the Corporation is then legally permitted to
pay such dividends.

      (c)   No interest or sum of money in lieu of interest shall be payable in
respect of any dividend not paid on a Dividend Payment Date or any other late
payment. The Corporation will also not pay Holders of the Convertible Preferred
Stock any dividend in excess of the full dividends on the Convertible Preferred
Stock that are payable as described above.

      (d)   Dividends in arrears on the Convertible Preferred Stock not declared
for payment or not paid on any Dividend Payment Date may later be declared by
the Board, or a duly authorized committee thereof, and paid on any date fixed by
the Board, or a duly authorized committee thereof, whether or not a Dividend
Payment Date, to the Holders of record as they appear on the stock register of
the Corporation on a record date selected by the Board, or a duly authorized
committee thereof, which shall (i) not precede the date the Board, or an
authorized committee thereof, declares the dividend payable and (ii) not be more
than 60 days prior to the date the dividend is paid.

      (4)   Payment Restrictions. (a) Unless all accrued, cumulated and unpaid
dividends on the Convertible Preferred Stock for all prior Dividend Periods have
been paid, the Corporation may not:


            (i)   declare or pay any dividend or make any distribution of assets
      on any Junior Securities, other than dividends or distributions in the
      form of Junior Securities and cash solely in lieu of fractional shares in
      connection with any such dividend or distribution;

            (ii)  redeem, purchase or otherwise acquire any Junior Securities or
      pay or make any monies available for a sinking fund for such Junior
      Securities, other than (A) upon conversion or exchange for other Junior
      Securities, (B) redemptions or purchases of any Series A Preferred Stock
      purchase rights or (C) the purchase of fractional interests in shares of
      any Junior Securities pursuant to the conversion or exchange provisions of
      such Junior Securities; or

            (iii) redeem, purchase or otherwise acquire any Parity Securities,
      except upon conversion into or exchange for other Parity Securities or
      Junior Securities and cash solely in lieu of fractional shares in
      connection with any such conversion or exchange, provided, however, that
      in the case of a redemption, purchase or other acquisition of Parity
      Securities upon conversion into or exchange for other Parity Securities
      (A) the aggregate amount of the liquidation preference of such other
      Parity Securities does not exceed the aggregate amount of the liquidation
      preference, plus accrued, cumulated and unpaid dividends, of the Parity
      Securities that are converted into or exchanged for such other Parity
      Securities, (B) the aggregate number of shares of Common Stock issuable
      upon conversion, redemption or exchange of such other Parity Securities
      does not exceed the aggregate number of shares of Common Stock issuable
      upon conversion, redemption or exchange of the Parity Securities that are
      converted into or exchanged for such other Parity Securities and (C) such
      other Parity Securities contain terms and conditions (including, without
      limitation, with respect to the payment of dividends, dividend rates,
      liquidation preferences, voting and representation rights, payment
      restrictions, anti-dilution rights, change of control rights, covenants,
      remedies and conversion and redemption rights) that are not materially
      less favorable, taken as a whole, to the Corporation or the Holders of the
      Convertible Preferred Stock than those contained in the Parity Securities
      that are converted or exchanged for such other Parity Securities.


                                      B-2

      (5)   Voting Rights. (a) Except as otherwise required by law, the
Certificate of Incorporation or set forth in this Section 5, Holders of the
Convertible Preferred Stock are not entitled to any voting rights and their
consent shall not be required for the taking of any corporate action.

      (b)   So long as any shares of Convertible Preferred Stock are
outstanding, the Corporation will not, without the approval of the Holders of at
least two-thirds of the shares of Convertible Preferred Stock then outstanding,
given in person or by proxy either at an annual meeting or at a special meeting
called for that purpose, at which the Holders of the Convertible Preferred Stock
shall vote separately as a single class, amend, alter or repeal (by merger,
consolidation, combination, reclassification or otherwise) any of the provisions
of the Corporation's Certificate of Incorporation so as to affect adversely the
rights, preferences or voting powers of the Holders of the Convertible Preferred
Stock; provided that any amendment of the provisions of the Certificate of
Incorporation so as to issue, authorize or increase the authorized amount of, or
issue or authorize any obligation or security convertible into or evidencing a
right to purchase, any Parity Securities or Junior Securities shall be deemed
not to affect adversely the rights, preferences or voting powers of the Holders
of the Convertible Preferred Stock. Notwithstanding anything in this Section 5
to the contrary, any amendment, alteration or repeal of any of the provisions of
the Corporation's Certificate of Incorporation occurring in connection with any
merger or consolidation of the Corporation of the type described in Section
14(e)(i) or any statutory exchange of securities of the Corporation with another
Person (other than in connection with a merger or acquisition) of the type
described in Section 14(e)(iv) shall be deemed not to adversely affect the
rights, preferences or voting power of the Holders of the Convertible Preferred
Stock, provided that, subject to Section 10, in the event the Corporation does
not survive the transaction, the shares of the Convertible Preferred Stock will
become shares of the successor Person, having in respect of such successor
Person the same rights, preferences or voting powers of the Holders of the
Convertible Preferred Stock immediately prior to the consummation of such
merger, consolidation, or statutory exchange and shall be convertible into the
kind and amount of net cash, securities and other property as determined in
accordance with Section 14(e) hereof, provided further that following any such
merger, consolidation or statutory exchange, such successor Person shall succeed
to and be substituted for, and may exercise all of the rights and powers of the
Corporation under the Convertible Preferred Stock.

      (c)   If at any time dividends on the then-outstanding shares of
Convertible Preferred Stock or any other class or series of Preferred Shares in
an amount equivalent to six quarterly dividends, whether or not consecutive,
shall not have been (i) paid or (ii)(A) declared and (B) a sum sufficient for
the payment thereof set aside, the holders of Preferred Shares (including the
Convertible Preferred Stock), voting separately as a single class, shall be
entitled to increase the authorized number of directors on the Board by two and
elect such two directors (the "PREFERRED STOCK DIRECTORS") at the next annual or
special meeting of the shareholders called in the manner described below. At any
such annual or special meeting of the shareholders, or any adjournment thereof,
if the holders of at least a majority of the Preferred Shares then outstanding
shall be present or represented by proxy, then, (1) by vote of the holders of at
least a majority of the Preferred Shares, voting as a class, then present or so
represented, the authorized number of directors of the Corporation shall be
increased by two, and (2) at such meeting the holders of the Preferred Shares,
voting as a class, shall be entitled to elect the


                                      B-3

Preferred Stock Directors by vote of the holders of at least a majority of the
Preferred Shares then present or so represented. Such right of the holders of
the Preferred Shares to elect the Preferred Stock Directors may be exercised
until all dividends in default on such Preferred Shares shall have been (i) paid
in full or (ii)(A) declared and (B) a sum sufficient for the payment thereof set
aside. When so paid or provided for, (i) the right of the holders of Preferred
Shares to elect the Preferred Stock Directors shall cease, (ii) the terms of all
of the Preferred Stock Directors shall terminate at the next annual meeting, and
(iii) the authorized number of directors of the Corporation shall be reduced
accordingly. Not later than 40 days after such entitlement arises, the Board
will convene a special meeting of the holders of Preferred Shares for the above
purpose. If the Board fails to convene such meeting within such 40-day period,
the holders of 10% of the outstanding Preferred Shares, considered as a single
class, will be entitled to convene such meeting to elect the initial Preferred
Stock Directors. Any director who shall have been elected by the holders of
Preferred Shares as a class pursuant to this Section 5(c) may be removed at any
time, either for or without cause by, and only by, the affirmative vote of the
holders of record of a majority of the outstanding Preferred Shares given at a
special meeting of such shareholders called for such purpose by the Corporation
or at the annual meeting of shareholders, and any vacancy created by such
removal may also be filled at such meeting. Any vacancy caused by the death or
resignation of a director who shall have been elected by the holders of
Preferred Shares as a class pursuant to this Section 5(c) may be filled only by
the holders of outstanding Preferred Shares at a meeting called for such purpose
by the Corporation. The provisions of the Certificate of Incorporation and
By-laws of the Corporation relating to the convening and conduct of special
meetings of shareholders and the nomination of directors will apply with respect
to any special meeting of the holders of Preferred Shares; provided that the
notice of the nomination need only be delivered to the Secretary of the
Corporation not more than 10 days after the Corporation (or the holders of 10%
of the outstanding Preferred Shares, if applicable) has notified the holders of
Preferred Shares of the date of the special meeting to elect the initial
Preferred Stock Directors.

      (d)   So long as any of the Convertible Preferred Stock is outstanding,
the Corporation will not, without the approval of the Holders of at least
two-thirds of the shares of Convertible Preferred Stock then outstanding and any
class or series of Parity Securities then outstanding, voting together as a
single class, given in person or by proxy either at an annual meeting or at a
special meeting called for that purpose:

            (i)   reclassify any of the Corporation's authorized shares into any
      shares of any class, or any obligation or security convertible into or
      evidencing a right to purchase such shares, ranking senior to the
      Convertible Preferred Stock as to payment of dividends or distribution of
      assets upon the dissolution, liquidation or winding up of the Corporation;
      or

            (ii)  issue, authorize or increase the authorized amount of, or
      issue or authorize any obligation or security convertible into or
      evidencing a right to purchase, any stock of any class or series ranking
      senior to the Convertible Preferred Stock as to payment of dividends or
      distribution of assets upon the dissolution, liquidation or winding up of
      the Corporation; provided that the Corporation may issue, authorize or
      increase the authorized amount of, or issue or authorize any obligation or
      security convertible into or evidencing a right to purchase, any shares of
      capital stock ranking on a


                                      B-4


      parity with or junior to the Convertible Preferred Stock as to payment of
      dividends or distribution of assets upon the dissolution, liquidation or
      winding up of the Corporation without the vote of the Holders of the
      Convertible Preferred Stock.

      (e)   In exercising the voting rights set forth in this Section 5, each
share of Convertible Preferred Stock shall have one vote per share. In any case
where the Holders of the Convertible Preferred Stock are entitled to vote as a
class with holders of Parity Securities or other classes or series of Preferred
Shares, each class or series shall have a number of votes proportionate to the
aggregate liquidation preference of its outstanding shares.

      (6)   Liquidation, Dissolution or Winding Up. (a) In the event of any
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation, subject to the rights of holders of any shares of capital stock of
the Corporation then outstanding ranking senior to or pari passu with the
Convertible Preferred Stock in respect of distributions upon liquidation,
dissolution or winding up of the Corporation and before any amount shall be paid
or distributed with respect to holders of any shares of capital stock of the
Corporation then outstanding ranking junior to the Convertible Preferred Stock
in respect of distributions upon liquidation, dissolution or winding up of the
Corporation, the Holders of the Convertible Preferred Stock at the time
outstanding will be entitled to receive, out of the net assets of the
Corporation legally available for distribution to shareholders, a liquidating
distribution in the amount of $50.00 per share, subject to adjustment as
provided for in Section 18(c), plus an amount equal to the sum of all accrued,
cumulated and unpaid dividends, whether or not declared, for the portion of the
then-current Dividend Period until the payment date and all prior Dividend
Periods and such Holders shall be deemed to be the Holders of record for such
Dividend Periods or portions thereof. After the payment to the Holders of the
Convertible Preferred Stock of the full amounts provided for in this Section
6(a), the Holders of the Convertible Preferred Stock will have no right or claim
to any of the Corporation's remaining assets.

      (b)   For the purpose of this Section 6, none of the following shall
constitute or be deemed to constitute a voluntary or involuntary liquidation,
dissolution or winding up of the Corporation:

            (i)   the sale, transfer, lease or conveyance of all or
      substantially all of the Corporation's property or business;

            (ii)  the consolidation or merger of the Corporation with or into
      any other Person; or

            (iii) the consolidation or merger of any other Person with or into
      the Corporation.

      (c)   If, upon any voluntary or involuntary liquidation, dissolution or
winding up of the Corporation, the amounts payable with respect to the
Convertible Preferred Stock then outstanding are not paid in full as provided in
Section 6(a) hereof, no distribution shall be made on account of any securities
ranking pari passu with the Convertible Preferred Stock as to the distribution
of assets upon such liquidation, dissolution or winding up, unless a pro rata
distribution is made on the Convertible Preferred Stock. The Holders of the
Convertible



                                      B-5


Preferred Stock then outstanding and the holders of any such securities then
outstanding shall share ratably in any distribution of assets upon such
liquidation, dissolution or winding up. The amount allocable to each series of
such securities then outstanding will be based on the proportion of their full
respective liquidation preference to the aggregate liquidation preference of the
outstanding shares of each such series.

      (d)   Written notice of any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, stating the payment date or dates
when, and the place or places where, the amounts distributable to holders of
Convertible Preferred Stock in such circumstances shall be payable, shall be
given by first-class mail, postage prepaid, mailed not less than twenty calendar
days prior to any payment date stated therein, to the Holders of Convertible
Preferred Stock, at the address shown on the books of the Corporation or the
Transfer Agent; provided, however, that a failure to give notice as provided
above or any defect therein shall not affect the Corporation's ability to
consummate a voluntary or involuntary liquidation, dissolution or winding up of
the Corporation.

      (7)   Mandatory Conversion on the Mandatory Conversion Date. (a) Each
share of Convertible Preferred Stock will automatically convert (unless
previously converted at the option of the Holder in accordance with Section 8
hereof, converted at the option of the Corporation pursuant to Section 9 hereof
or pursuant to an exercise of a Merger Early Conversion right pursuant to
Section 10 hereof) on the Mandatory Conversion Date, into a number of shares of
Common Stock equal to the Conversion Rate.

      (b)   The "CONVERSION RATE" shall be as follows:

            (i)   if the Applicable Market Value of the Common Stock is equal to
or greater than $22.27 (the "THRESHOLD APPRECIATION PRICE"), then the Conversion
Rate shall be equal to 2.2451 shares of Common Stock per share of Convertible
Preferred Stock (the "MINIMUM CONVERSION RATE"), which is equal to $50.00
divided by the Threshold Appreciation Price);

            (ii)  if the Applicable Market Value of the Common Stock is less
than the Threshold Appreciation Price but greater than $17.96 (the "INITIAL
PRICE"), then the Conversion Rate shall be equal to $50.00 divided by the
Applicable Market Value of the Common Stock;

            (iii) if the Applicable Market Value of the Common Stock is less
than or equal to the Initial Price, then the Conversion Rate shall be equal to
2.7840 shares of Common Stock per share of Convertible Preferred Stock (the
"MAXIMUM CONVERSION RATE"), which is equal to $50.00 divided by the Initial
Price; and

            (iv)  the Minimum Conversion Rate, the Maximum Conversion Rate, the
Threshold Appreciation Price and the Initial Price are each subject to
adjustment in accordance with the provisions of Section 14 hereof.

      (c)   The Holders of Convertible Preferred Stock on the Mandatory
Conversion Date shall have the right to receive an amount in cash equal to all
accrued, cumulated and unpaid dividends on the Convertible Preferred Stock,
whether or not declared prior to that date, for the


                                      B-6


then current Dividend Period until the Mandatory Conversion Date and all prior
Dividend Periods (other than previously declared dividends on the Convertible
Preferred Stock payable to Holders of record as of a prior date), provided that
the Corporation is legally permitted to pay such dividends at such time.

      (8)   Early Conversion at the Option of the Holder. (a) Shares of the
Convertible Preferred Stock are convertible, in whole or in part at the option
of the Holder thereof ("EARLY CONVERSION") at any time prior to the Mandatory
Conversion Date, into shares of Common Stock at the Minimum Conversion Rate,
subject to adjustment as set forth in Section 14 hereof.

      (b)   Any written notice of conversion pursuant to Section 8 hereof shall
be duly executed by the Holder, and specify:

            (i)   the number of shares of Convertible Preferred Stock to be
      converted;

            (ii)  the name(s) in which such Holder desires the shares of Common
      Stock issuable upon conversion to be registered and whether such shares of
      Common Stock are to be issued in book-entry or certificated form (subject
      to compliance with applicable legal requirements if any of such
      certificates are to be issued in a name other than the name of the
      Holder);

            (iii) if certificates are to be issued, the address to which such
      Holder wishes delivery to be made of such new certificates to be issued
      upon such conversion; and

            (iv)  any other transfer forms, tax forms or other relevant
      documentation required and specified by the Transfer Agent, if necessary,
      to effect the conversion.

      (c)   If specified by the Holder in the notice of conversion that shares
of Common Stock issuable upon conversion of the Convertible Preferred Stock
shall be issued to a person other than the Holder surrendering the shares of
Convertible Preferred Stock being converted, the Holder shall pay or cause to be
paid any transfer or similar taxes payable in connection with the shares of
Common Stock so issued.

      (d)   Upon receipt by the Transfer Agent of a completed and duly executed
notice of conversion as set forth in Section 8(b), compliance with Section 8(c),
if applicable, and upon surrender of a certificate representing share(s) of
Convertible Preferred Stock to be converted (if held in certificated form), the
Corporation shall, within three Business Days or as soon as possible thereafter,
issue and shall instruct the Transfer Agent to register the number of shares of
Common Stock to which such Holder shall be entitled upon conversion in the
name(s) specified by such Holder in the notice of conversion. If a Holder elects
to hold its shares of Common Stock issuable upon conversion of the Convertible
Preferred Stock in certificated form, the Corporation shall promptly send or
cause to be sent, by hand delivery (with receipt to be acknowledged) or by
first-class mail, postage prepaid, to the Holder thereof, at the address
designated by such Holder in the written notice of conversion, a certificate or
certificates representing the number of shares of Common Stock to which such
Holder shall be entitled upon


                                      B-7


conversion. In the event that there shall have been surrendered a certificate or
certificates representing shares of Convertible Preferred Stock, only part of
which are to be converted, the Corporation shall issue and deliver to such
Holder or such Holder's designee in the manner provided in the immediately
preceding sentence a new certificate or certificates representing the number of
shares of Convertible Preferred Stock that shall not have been converted.

      (e)   The issuance by the Corporation of shares of Common Stock upon a
conversion of shares of Convertible Preferred Stock in accordance with the terms
hereof shall be deemed effective immediately prior to the close of business on
the day of receipt by the Transfer Agent of the notice of conversion and other
documents, if any, set forth in Section 8(b) hereof, compliance with Section
8(c), if applicable, and the surrender by such Holder or such Holder's designee
of the certificate or certificates representing the shares of Convertible
Preferred Stock to be converted (if held in certificated form), duly assigned or
endorsed for transfer to the Corporation (or accompanied by duly executed stock
powers relating thereto).

      (f)   A Holder of a share of Convertible Preferred Stock on the Early
Conversion Date with respect to such share shall have the right to receive all
accrued, cumulated and unpaid dividends, whether or not declared, for the
portion of the then-current Dividend Period until the Early Conversion Date and
all prior Dividend Periods (other than previously declared dividends on the
Convertible Preferred Stock payable to Holders of record as of a prior date),
provided that the Corporation is then legally permitted to pay such dividends.
Except as described above, upon any optional conversion of the Convertible
Preferred Stock, the Corporation will make no payment or allowance for unpaid
dividends on the Convertible Preferred Stock.

      (9)   Provisional Conversion. (a) Prior to the Mandatory Conversion Date,
if the Closing Price of the Common Stock has exceeded 150% of the Threshold
Appreciation Price for at least 20 Trading Days within a period of 30
consecutive Trading Days ending on the Trading Day prior to the date (the
"PROVISIONAL CONVERSION NOTICE DATE") on which the Corporation notifies the
Holders (pursuant to clause (b) below) that it is exercising its option to cause
the conversion of the Convertible Preferred Stock pursuant to this Section 9,
the Corporation may, at its option, cause the conversion of all, but not less
than all, the shares of Convertible Preferred Stock then outstanding into shares
of Common Stock at the Minimum Conversion Rate for each share of Convertible
Preferred Stock, subject to adjustment as set forth in Section 14. The
Corporation shall be able to cause this conversion only if, in addition to
issuing the Holders shares of Common Stock, the Corporation is then legally
permitted to, and does, pay the Holders in cash (i) an amount equal to any
accrued, cumulated and unpaid dividends on the shares of Convertible Preferred
Stock then outstanding, whether or not declared (other than previously declared
dividends on the Convertible Preferred Stock payable to Holders of record as of
a prior date), plus (ii) the present value of all remaining future dividend
payments on the shares of Convertible Preferred Stock then outstanding through
and including the Mandatory Conversion Date. The present value of the remaining
future dividend payments will be computed using a discount rate equal to the
Treasury Yield.

      (b)   A written notice (the "PROVISIONAL CONVERSION NOTICE") shall be sent
by or on behalf of the Corporation, by first class mail, postage prepaid, to the
Holders of record as they appear on the stock register of the Corporation on the
Provisional Conversion Notice Date


                                      B-8


(i) notifying such Holders of the election of the Corporation to convert and of
the Provisional Conversion Date (as defined below), which date shall not be less
than 30 days nor be more than 60 days after the Provisional Conversion Notice
Date, and (ii) stating the Corporate Trust Office of the Transfer Agent at which
the shares of Convertible Preferred Stock called for conversion shall, upon
presentation and surrender of the certificate(s) (if such shares are held in
certificated form) evidencing such shares, be converted, and the Minimum
Conversion Rate to be applied thereto. The Corporation shall also issue a press
release containing such information and publish such information on its website
on the World Wide Web, provided that failure to issue such press release or
publish such information on the Corporation's website shall not act to prevent
or delay conversion pursuant to this Section 9.

      (c)   The Corporation shall deliver to the Transfer Agent irrevocable
written instructions authorizing the Transfer Agent, on behalf and at the
expense of the Corporation, to cause the Provisional Conversion Notice to be
duly mailed as soon as practicable after receipt of such irrevocable
instructions from the Corporation and in accordance with the above provisions.
The shares of Common Stock to be issued upon conversion of the Convertible
Preferred Stock pursuant to this Section 9 and all funds necessary for the
payment in cash of (i) an amount equal to any accrued, cumulated and unpaid
dividends on the shares of Convertible Preferred Stock then outstanding, whether
or not declared (other than previously declared dividends on the Convertible
Preferred Stock payable to Holders of record as of a prior date), plus (ii) the
present value of all remaining future dividend payments on the shares of
Convertible Preferred Stock then outstanding through and including the Mandatory
Conversion Date, shall be deposited with the Transfer Agent in trust at least
one Business Day prior to the Provisional Conversion Date, for the pro rata
benefit of the Holders of record as they appear on the stock register of the
Corporation, so as to be and continue to be available therefor. Neither failure
to mail such Provisional Conversion Notice to one or more such Holders nor any
defect in such Provisional Conversion Notice shall affect the sufficiency of the
proceedings for conversion as to other Holders.

      (d)   If a Provisional Conversion Notice shall have been given as
hereinbefore provided, then each Holder shall be entitled to all preferences and
relative, participating, optional and other special rights accorded by this
Certificate of Amendment until and including the Provisional Conversion Date.
From and after the Provisional Conversion Date, upon delivery by the Corporation
of the Common Stock and payment of the funds to the Transfer Agent as described
in paragraph (c) above, the Convertible Preferred Stock shall no longer be
deemed to be outstanding, and all rights of such Holders shall cease and
terminate, except the right of the Holders, upon surrender of certificates
therefor, to receive Common Stock and any amounts to be paid hereunder.

      (e)   The deposit of monies in trust with the Transfer Agent up to the
amount necessary for the Provisional Conversion shall be irrevocable except that
the Corporation shall be entitled to receive from the Transfer Agent the
interest or other earnings, if any, earned on any monies so deposited in trust,
and the Holders of the shares converted shall have no claim to such interest or
other earnings, and any balance of monies so deposited by the Corporation and
unclaimed by the Holders entitled thereto at the expiration of two years from
the Provisional Conversion Date shall be repaid, together with any interest or
other earnings thereon, to the Corporation, and after any such repayment, the
Holders of the shares entitled to the funds so repaid to the


                                      B-9


Corporation shall look only to the Corporation for such payment without
interest.

      (10)  Early Conversion Upon Cash Merger. (a) In the event of a merger or
consolidation of the Corporation of the type described in Section 14(e)(i) in
which the Common Stock outstanding immediately prior to such merger or
consolidation is exchanged for consideration consisting of at least 30% cash or
cash equivalents (any such event, a "CASH MERGER"), then the Holders of the
Convertible Preferred Stock shall have the right to convert their shares of
Convertible Preferred Stock prior to the earlier of the Mandatory Conversion
Date and the Provisional Conversion Notice Date, provided that the Provisional
Conversion Date occurs within the period contemplated by Section 9(b) hereof,
(such right of the Holders to convert their shares pursuant to this Section
10(a) being the "MERGER EARLY CONVERSION") as provided herein.

      (b)   On or before the fifth Business Day after the consummation of a Cash
Merger, the Corporation or the corporation surviving the Cash Merger (the
"SURVIVING CORPORATION") or, at the request and expense of the Surviving
Corporation, the Transfer Agent, shall give all Holders notice of the occurrence
of the Cash Merger and of the Merger Early Conversion right arising as a result
thereof. The Surviving Corporation shall also deliver a copy of such notice to
the Transfer Agent. Each such notice shall contain:

            (i)   the date, which shall be not less than 20 nor more than 35
      calendar days after the date of such notice, on which the Merger Early
      Conversion will be effected (such date being the "MERGER EARLY CONVERSION
      DATE");

            (ii)  the date, which shall be on, or one Business day prior to, the
      Merger Early Conversion Date, by which the Merger Early Conversion right
      must be exercised;

            (iii) the Conversion Rate in effect on the Trading Day immediately
      preceding such Cash Merger (calculated as if the Trading Day immediately
      preceding such Cash Merger were the Mandatory Conversion Date) and the
      kind and amount of securities, cash and other property receivable per
      share of Convertible Preferred Stock by the Holder upon conversion of
      shares of Convertible Preferred Stock pursuant to Section 10(d); and

            (iv)  the instructions a Holder must follow to exercise the Merger
      Early Conversion right.

      (c)   To exercise a Merger Early Conversion right, a Holder shall deliver
to the Transfer Agent at its Corporate Trust Office by 5:00 p.m., New York City
time on or before the date by which the Merger Early Conversion right must be
exercised as specified in the notice, the certificate(s) (if such shares are
held in certificated form) evidencing the shares of Convertible Preferred Stock
with respect to which the Merger Early Conversion right is being exercised, duly
assigned or endorsed for transfer to the Surviving Corporation, or accompanied
by duly executed stock powers relating thereto, or in blank, with a written
notice to the Surviving Corporation stating the Holder's intention to convert
early in connection with the Cash Merger containing the


                                      B-10


information set forth in Section 8(b) and providing the Surviving Corporation
with payment instructions.

      (d)   If the Holder exercises its Merger Early Conversion right pursuant
to the terms hereof, on the Merger Early Conversion Date the Surviving
Corporation shall deliver or cause to be delivered the net cash, securities and
other property entitled to be received by such exercising Holder, determined by
assuming the Holder had converted its shares of Convertible Preferred Stock
immediately before the Cash Merger at the Conversion Rate in effect on the
Trading Day immediately preceding such Cash Merger calculated in accordance with
Section 7(b) hereof and that such Holder was not the counterparty to the Cash
Merger or an affiliate of such other party and did not exercise any rights of
election with respect to the kind or amount of consideration to be received. In
the event a Merger Early Conversion right is exercised by a Holder in accordance
with the terms hereof, (i) all references herein to Mandatory Conversion Date
shall be deemed to refer to such Merger Early Conversion Date and (ii) if a
Reorganization Event (other than the Cash Merger) has previously occurred,
"Applicable Market Value" shall be deemed to refer to the Applicable Market
Value of the Exchange Property as determined in accordance with Section 14(e).
If a Holder does not elect to exercise the Merger Early Conversion right
pursuant to this Section 10, in lieu of shares of Common Stock, the Surviving
Corporation shall deliver to such Holder on the Mandatory Conversion Date, the
Provisional Conversion Date or an Early Conversion Date, such net cash,
securities and other property as determined in accordance with Section 14(e)
hereof.

      (e)   Upon a Merger Early Conversion, the Transfer Agent shall, in
accordance with the instructions provided by the Holder thereof in the written
notice provided to the Surviving Corporation as set forth above, deliver to the
Holder such net cash, securities or other property issuable upon such Merger
Early Conversion, together with payment in lieu of any fraction of a share, as
provided herein.

      (f)   In the event that a Merger Early Conversion is effected with respect
to shares of Convertible Preferred Stock representing less than all the shares
of Convertible Preferred Stock held by a Holder, upon such Merger Early
Conversion the Surviving Corporation shall execute and the Transfer Agent shall,
unless otherwise instructed in writing, countersign and deliver to the Holder
thereof, at the expense of the Surviving Corporation, a certificate evidencing
the shares of Convertible Preferred Stock as to which Merger Early Conversion
was not effected.

      (g)   In the event that a Merger Early Conversion is effected with respect
to shares of Convertible Preferred Stock, the Holder of such shares on the
Merger Early Conversion Date with respect to such share shall have the right to
receive an amount in cash equal to all accrued, cumulated and unpaid dividends,
whether or not declared prior to the Merger Early Conversion Date, for the
portion of the then-current Dividend Period until the Merger Early Conversion
Date and all prior Dividend Periods (other than previously declared dividends on
the Convertible Preferred Stock payable to Holders of record as of a prior
date), provided that at such time the Corporation is then legally permitted to
pay such dividends.

      (11)  Conversion Procedures. (a) Upon issuance and delivery to the
Transfer Agent of certificates representing shares of the Common Stock to be
delivered upon conversion


                                      B-11


of the shares of Convertible Preferred Stock on the Mandatory Conversion Date,
the Provisional Conversion Date, the Merger Early Conversion Date or any Early
Conversion Date (collectively, a "CONVERSION DATE"), dividends on any shares of
Convertible Preferred Stock converted to Common Stock shall cease to accrue and
cumulate, and such shares of Convertible Preferred Stock shall cease to be
outstanding, in each case, subject to the right of Holders of such shares to
receive any accrued, cumulated and unpaid dividends on such shares to which they
are otherwise entitled pursuant to Section (7), (8) or (10) hereof, as
applicable.

      (b)   The person or persons entitled to receive the Common Stock issuable
upon such conversion shall be treated for all purposes as the record holder(s)
of such shares of Common Stock as of the close of business on the Mandatory
Conversion Date, the Merger Early Conversion Date, the Provisional Conversion
Date or any Early Conversion Date, as the case may be. No allowance or
adjustment, except as set forth in Section 14, shall be made in respect of
dividends payable to holders of Common Stock of record as of any date prior to
such effective date. Prior to such effective date, shares of Common Stock
issuable upon conversion of any shares of Convertible Preferred Stock shall not
be deemed outstanding for any purpose, and Holders of shares of Convertible
Preferred Stock shall have no rights with respect to the Common Stock (including
voting rights, rights to respond to tender offers for the Common Stock and
rights to receive any dividends or other distributions on the Common Stock) by
virtue of holding shares of Convertible Preferred Stock.

      (c)   Shares of Convertible Preferred Stock duly converted in accordance
with this Certificate of Amendment, or otherwise reacquired by the Corporation,
will resume the status of authorized and unissued Preferred Stock, undesignated
as to series and available for future issuance.

      (d)   In the event that a Holder of shares of Convertible Preferred Stock
shall not by written notice designate the name in which shares of Common Stock
to be issued upon conversion of such shares should be registered or the address
to which the certificate or certificates representing such shares should be
sent, the Corporation shall be entitled to register such shares, and make such
payment, in the name of the Holder of such Convertible Preferred Stock as shown
on the records of the Corporation and to send the certificate or certificates
representing such shares to the address of such Holder shown on the records of
the Corporation.

      (12)  Reservation of Common Stock. (a) The Corporation shall at all times
reserve and keep available out of its authorized and unissued Common Stock or
shares held in the treasury of the Corporation, solely for issuance upon the
conversion of shares of Convertible Preferred Stock as herein provided, free
from any preemptive or other similar rights, such number of shares of Common
Stock as shall from time to time be issuable upon the conversion of all the
shares of Convertible Preferred Stock then outstanding. For purposes of this
Section 12(a), the number of shares of Common Stock that shall be deliverable
upon the conversion of all outstanding shares of Convertible Preferred Stock
shall be computed as if at the time of computation all such outstanding shares
were held by a single Holder.

      (b)   Notwithstanding the foregoing, the Corporation shall be entitled to
deliver upon conversion of shares of Convertible Preferred Stock, as herein
provided, shares of Common Stock reacquired and held in the treasury of the
Corporation (in lieu of the issuance of authorized


                                      B-12


and unissued shares of Common Stock), so long as any such treasury shares are
free and clear of all liens, charges, security interests or encumbrances (other
than liens, charges, security interests and other encumbrances created by the
Holders).

      (c)   All shares of Common Stock delivered upon conversion of the
Convertible Preferred Stock shall be duly authorized, validly issued, fully paid
and non-assessable, free and clear of all liens, claims, security interests and
other encumbrances (other than liens, charges, security interests and other
encumbrances created by the Holders).

      (d)   Prior to the delivery of any securities that the Corporation shall
be obligated to deliver upon conversion of the Convertible Preferred Stock, the
Corporation shall use its reasonable best efforts to comply with all federal and
state laws and regulations thereunder requiring the registration of such
securities with, or any approval of or consent to the delivery thereof by, any
governmental authority.

      (e)   The Corporation hereby covenants and agrees that, if at any time the
Common Stock shall be listed on the New York Stock Exchange or any other
national securities exchange or automated quotation system, the Corporation
will, if permitted by the rules of such exchange or automated quotation system,
list and keep listed, so long as the Common Stock shall be so listed on such
exchange or automated quotation system, all Common Stock issuable upon
conversion of the Convertible Preferred Stock; provided, however, that if the
rules of such exchange or automated quotation system permit the Corporation to
defer the listing of such Common Stock until the first conversion of Convertible
Preferred Stock into Common Stock in accordance with the provisions hereof, the
Corporation covenants to list such Common Stock issuable upon conversion of the
Convertible Preferred Stock in accordance with the requirements of such exchange
or automated quotation system at such time.

      (13)  Fractional Shares. (a) No fractional shares of Common Stock will be
issued as a result of any conversion of shares of Convertible Preferred Stock.

      (b)   In lieu of any fractional share of Common Stock otherwise issuable
in respect of any mandatory conversion pursuant to Section 7 hereof, any
conversion at the option of the Corporation pursuant to Section 9 hereof or a
conversion at the option of the holder pursuant to Section 8 or Section 10
hereof, the Corporation shall pay an amount in cash (computed to the nearest
cent) equal to the same fraction of:

            (i)   in the case of a conversion pursuant to Section 7 or Section 9
      hereof or a Merger Early Conversion pursuant to Section 10, the Current
      Market Price; or

            (ii)  in the case of an Early Conversion pursuant to Section 8
      hereof, the Closing Price of the Common Stock determined as of the second
      Trading Day immediately preceding the effective date of conversion.

      (c)   If more than one share of the Convertible Preferred Stock is
surrendered for conversion at one time by or for the same Holder, the number of
full shares of Common Stock issuable upon conversion thereof shall be computed
on the basis of the aggregate number of shares of the Convertible Preferred
Stock so surrendered.


                                      B-13


      (14)  Anti-Dilution Adjustments to the Fixed Conversion Rates. (a) Each
Fixed Conversion Rate and the number of shares of Common Stock to be delivered
upon conversion shall be subject to the following adjustments.

            (i)   Stock Dividends and Distributions. In case the Corporation
      shall pay or make a dividend or other distribution on the Common Stock in
      shares of Common Stock, each Fixed Conversion Rate, as in effect at the
      opening of business on the day following the date fixed for the
      determination of shareholders entitled to receive such dividend or other
      distribution, shall be increased by dividing such Fixed Conversion Rate by
      a fraction of which the numerator shall be the number of shares of Common
      Stock outstanding at the close of business on the date fixed for such
      determination and the denominator shall be the sum of such number of
      shares of Common Stock outstanding and the total number of shares of
      Common Stock constituting such dividend or other distribution, such
      increase to become effective immediately after the opening of business on
      the day following the date fixed for such determination. For the purposes
      of this sub-section (i), the number of shares of Common Stock at the time
      outstanding shall not include shares held in the treasury of the
      Corporation but shall include any shares issuable in respect of any scrip
      certificates issued in lieu of fractions of shares of Common Stock. The
      Corporation will not pay any dividend or make any distribution on shares
      of Common Stock held in the treasury of the Corporation.

            (ii)  Subdivisions, Splits and Combinations of the Common Stock. In
      case outstanding shares of Common Stock shall be subdivided or split into
      a greater number of shares of Common Stock, each Fixed Conversion Rate in
      effect at the opening of business on the day following the day upon which
      such subdivision or split becomes effective shall be proportionately
      increased, and, conversely, in case outstanding shares of Common Stock
      shall each be combined into a smaller number of shares of Common Stock,
      such Fixed Conversion Rate in effect at the opening of business on the day
      following the day upon which such combination becomes effective shall be
      proportionately reduced, such increase or reduction, as the case may be,
      to become effective immediately after the opening of business on the day
      following the day upon which such subdivision, split or combination
      becomes effective.

            (iii) Issuance of Stock Purchase Rights. In case the Corporation
      shall issue rights or warrants to all holders of its Common Stock (other
      than rights or warrants issued pursuant to a dividend reinvestment plan or
      share purchase plan or other similar plans), entitling such holders, for a
      period of up to 45 days from the date of issuance of such rights or
      warrants, to subscribe for or purchase shares of Common Stock at a price
      per share less than the Current Market Price on the date fixed for the
      determination of shareholders entitled to receive such rights or warrants,
      each Fixed Conversion Rate in effect at the opening of business on the day
      following the date fixed for such determination shall be increased by
      multiplying such Fixed Conversion Rate by a fraction, the numerator of
      which shall be the number of shares of Common Stock outstanding at the
      close of business on the date fixed for such determination plus the number
      of shares of Common Stock so offered for subscription or purchase and the
      denominator of which shall be the number of shares of Common Stock
      outstanding at the close of business on the date fixed for such
      determination plus the number of shares of


                                      B-14


      Common Stock which the aggregate offering price of the total number of
      shares of Common Stock so offered for subscription or purchase would
      purchase at such Current Market Price, such increase to become effective
      immediately after the opening of business on the day following the date
      fixed for such determination. For the purposes of this clause (iii), the
      number of shares of Common Stock at any time outstanding shall not include
      shares held in the treasury of the Corporation but shall include any
      shares issuable in respect of any scrip certificates issued in lieu of
      fractions of shares of Common Stock. The Corporation shall not issue any
      such rights or warrants in respect of shares of Common Stock held in the
      treasury of the Corporation.

            (iv)  Debt or Asset Distribution. (A) In case the Corporation shall,
      by dividend or otherwise, distribute to all holders of its Common Stock
      evidences of its indebtedness, shares of capital stock, securities, cash
      or other assets (excluding any dividend or distribution referred to in
      Section 14(a)(i) or Section 14(a)(ii) hereof, any rights or warrants
      referred to in Section 14(a)(iii) hereof, any dividend or distribution
      paid exclusively in cash, any consideration payable in connection with a
      tender or exchange offer made by the Corporation or any subsidiary of the
      Corporation, and any dividend of shares of capital stock of any class or
      series, or similar equity interests, of or relating to a subsidiary or
      other business unit in the case of a Spin-Off referred to in Section
      14(a)(iv)(B) below), each Fixed Conversion Rate shall be adjusted so that
      it shall equal the rate determined by multiplying such Fixed Conversion
      Rate in effect immediately prior to the close of business on the date
      fixed for the determination of shareholders entitled to receive such
      distribution by a fraction, the numerator of which shall be the Current
      Market Price per share of the Common Stock on the date fixed for such
      determination and the denominator of which shall be such Current Market
      Price per share of the Common Stock less the then Fair Market Value of the
      portion of the evidences of indebtedness, shares of capital stock,
      securities, cash or other assets so distributed applicable to one share of
      Common Stock, such adjustment to become effective immediately prior to the
      opening of business on the day following the date fixed for the
      determination of shareholders entitled to receive such distribution. In
      any case in which this clause (iv)(A) is applicable, clause (iv)(B) of
      this Section 14(a) shall not be applicable.

                  (B)   In the case of a Spin-Off, each Fixed Conversion Rate in
      effect immediately before the close of business on the record date fixed
      for determination of shareholders entitled to receive that distribution
      will be increased by multiplying each Fixed Conversion Rate by a fraction,
      the numerator of which is the Current Market Price per share of the Common
      Stock plus the Fair Market Value of the portion of those shares of capital
      stock or similar equity interests so distributed applicable to one share
      of Common Stock and the denominator of which is the Current Market Price
      per share of the Common Stock. Any adjustment to the Conversion Rate under
      this clause (iv)(B) of this Section 14(a) will occur on the 15th Trading
      Day from, but excluding, the "ex-date" with respect to the Spin-Off.

            (v)   Cash Distributions. In case the Corporation shall distribute
      cash to all holders of the Common Stock immediately after the close of
      business on such date for determination, each Fixed Conversion Rate will
      be adjusted by multiplying such Fixed


                                      B-15


      Conversion Rate in effect immediately prior to the close of business on
      the date fixed for determination of the shareholders of the Corporation
      entitled to receive such distribution by a fraction, the numerator of
      which will be the Current Market Price of the Common Stock on the date
      fixed for such determination and the denominator of which will be the
      Current Market Price of the Common Stock on the date fixed for such
      determination minus the amount per share of such dividend or distribution;
      provided, that no adjustment will be made to either Fixed Conversion Rate
      for (i) any cash that is distributed in a Reorganization Event to which
      Section 14(e) applies or as part of a distribution referred to in
      paragraph (iv) of this Section 14(a), (ii) any dividend or distribution in
      connection with the liquidation, dissolution or winding up of the
      Corporation (iii) any consideration payable in connection with a tender or
      exchange offer made by the Corporation or any subsidiary of the
      Corporation or (iv) any cash dividends on the Common Stock to the extent
      that the aggregate cash dividend per share of Common Stock does not exceed
      (x) $0.055 in any fiscal quarter in the case of a quarterly dividend or
      (y) $0.22 in the prior twelve months in the case of an annual dividend
      (each such number, the "DIVIDEND THRESHOLD AMOUNT"). The Dividend
      Threshold Amount is subject to an inversely proportional adjustment
      whenever the Fixed Conversion Rates are adjusted, provided that no
      adjustment will be made to the Dividend Threshold Amount for any
      adjustment made to the Fixed Conversion Rates pursuant to this clause (v)
      or clause (iii), (iv), (vi), (vii) or (viii) of this Section 14(a).

            If an adjustment is required to be made under this clause (v) as a
      result of a distribution that is a quarterly or annual dividend, the
      adjustment shall be based upon the amount by which the distribution
      exceeds the applicable Dividend Threshold Amount. If an adjustment is
      required to be made under this clause as a result of a distribution that
      is not a quarterly or annual dividend, the adjustment shall be based upon
      the full amount of such distribution.

            (vi)  Self Tender Offers and Exchange Offers. In case a tender or
      exchange offer made by the Corporation or any subsidiary of the
      Corporation for all or any portion of the Common Stock shall expire and
      such tender or exchange offer (as amended upon the expiration thereof)
      shall require the payment to shareholders (based on the acceptance, up to
      any maximum specified in the terms of the tender or exchange offer, of
      Purchased Shares (as defined below in this Section)) of an aggregate
      consideration per share of Common Stock having a Fair Market Value that
      exceeds the Current Market Price per share of the Common Stock on the
      seventh Trading Day next succeeding the last date on which (the
      "EXPIRATION TIME") tenders or exchanges could have been made pursuant to
      such tender or exchange offer (as it may be amended), then, and in each
      such case, immediately prior to the opening of business on the eighth
      Trading Day after the date of the Expiration Time, each Fixed Conversion
      Rate shall be adjusted so that the same shall equal the rate determined by
      dividing such Fixed Conversion Rate in effect immediately prior to the
      opening of business on the eighth Trading Day after the Expiration Time by
      a fraction (A) the numerator of which shall be equal to (x) the product of
      (I) the Current Market Price per share of the Common Stock on the seventh
      Trading Day after the Expiration Time and (II) the number of shares of
      Common Stock outstanding (including any shares validly tendered and not
      withdrawn) at the Expiration Time less (y) the amount of cash plus the
      Fair Market Value of the aggregate


                                      B-16


      consideration payable to shareholders in the tender or exchange offer
      (assuming the acceptance, up to any maximum specified in the terms of the
      tender or exchange offer, of Purchased Shares), and (B) the denominator of
      which shall be equal to the product of (x) the Current Market Price per
      share of the Common Stock on the seventh Trading Day after the Expiration
      Time and (y) the number of shares of Common Stock outstanding (including
      any shares validly tendered and not withdrawn) as of the Expiration Time
      less the number of all shares validly tendered and not withdrawn as of the
      Expiration Time (the shares deemed so accepted, up to any such maximum,
      being referred to as the "PURCHASED SHARES").

            (vii) Third Party Tender Offers and Exchange Offers. In case any
      Person other than the Corporation or any subsidiary of the Corporation
      makes a payment in respect of a tender offer or exchange offer in which,
      as of the last time (the "OFFER EXPIRATION TIME") that tenders or
      exchanges may be made pursuant to such tender or exchange offer (as it
      shall have been amended), the Board of Directors is not recommending
      rejection of the offer, then each Fixed Conversion Rate will be adjusted
      by multiplying the Fixed Conversion Rate in effect immediately prior to
      the close of business on the date of the Offer Expiration Time by a
      fraction (A) the numerator of which will be the sum of (x) the Fair Market
      Value of the aggregate consideration payable to all holders of Common
      Stock based on the acceptance (up to any maximum specified in the terms of
      the tender or exchange offer) of all shares validly tendered or exchanged
      and not withdrawn as of the Offer Expiration Time (the shares deemed so
      accepted, up to any such maximum, being referred to as the "ACCEPTED
      PURCHASED SHARES") and (y) the product of the number of shares of Common
      Stock outstanding less any such Accepted Purchased Shares and the Current
      Market Price of the Common Stock on the seventh Trading Day next
      succeeding the Offer Expiration Time and (B) the denominator of which will
      be the product of the number of shares of Common Stock outstanding,
      including any such Accepted Purchased Shares, and the Current Market Price
      of the Common Stock on the seventh Trading Day next succeeding the Offer
      Expiration Time. Such adjustment shall become effective as of the opening
      of business on the eighth Trading Day following the Offer Expiration Time.

            The adjustment referred to in this clause (vii) will only be made if
      (1) the tender offer or exchange offer is for an amount that increases the
      offeror's ownership of common stock to more than 30% of the total shares
      of Common Stock outstanding; and (2) the cash and Fair Market Value of any
      other consideration included in the payment per share of Common Stock
      exceeds the Current Market Price of the Common Stock on the seventh
      Trading Day next succeeding the Offer Expiration Time.

            However, the adjustment referred to in this clause will not be made
      if as of the Offer Expiration Time, the offering documents disclose a plan
      or an intention to cause the Corporation to engage in a consolidation or
      merger or a sale of all or substantially all of the Corporation's assets.
      In the event the offeror is obligated to purchase shares pursuant to any
      such tender or exchange offer, but such Person is permanently prevented by
      applicable law from effecting any such purchases or all such purchases are
      rescinded, each Fixed Conversion Rate shall be readjusted to what would
      have been in effect if such tender or exchange offer had not been made.


                                      B-17


            (viii) Rights Plans. To the extent that the Corporation has a rights
      plan in effect on any Conversion Date, upon conversion of any Convertible
      Preferred Stock, Holders shall receive, in addition to the Common Stock,
      the rights under such rights plan, unless, prior to such Conversion Date,
      the rights have separated from the Common Stock, in which case each Fixed
      Conversion Rate will be adjusted at the time of separation of such rights
      as if the Corporation made a distribution to all holders of the Common
      Stock as described in clause (iv) above, subject to readjustment in the
      event of the expiration, termination or redemption of such rights.

      (b)   Adjustment for Tax Reasons. The Corporation may make such increases
in each Fixed Conversion Rate, in addition to any other increases required by
this Section 14, if the Board deems it advisable to avoid or diminish any income
tax to holders of the Common Stock resulting from any dividend or distribution
of shares (or issuance of rights or warrants to acquire shares) or from any
event treated as such for income tax purposes or for any other reasons; provided
that the same proportionate adjustment must be made to each Fixed Conversion
Rate.

      (c)   Calculation of Adjustments. (i) All adjustments to the Conversion
Rate shall be calculated to the nearest 1/10,000th of a share (or, if there is
not a nearest 1/10,000th of a share, to the next lower 1/10,000th of a share) of
Common Stock. Prior to the Mandatory Conversion Date, no adjustment in the
Conversion Rate shall be required unless such adjustment would require an
increase or decrease of at least one percent therein; provided, that any
adjustments which by reason of this subparagraph are not required to be made
shall be carried forward and taken into account in any subsequent adjustment;
provided further that on the Mandatory Conversion Date, adjustments to the
Conversion Rate will be made with respect to any such adjustment carried forward
and which has not been taken into account before such date. If an adjustment is
made to the Conversion Rate pursuant to Sections 14(a)(i), 14(a)(ii),
14(a)(iii), 14(a)(iv), 14(a)(v), 14(a)(vi), 14(a)(vii) or 14(b), an inversely
proportional adjustment shall also be made to the Threshold Appreciation Price
and the Initial Price solely for purposes of determining which of clauses (i),
(ii) and (iii) of Section 7(b) will apply on the Conversion Date. Such
adjustment shall be made by dividing each of the Threshold Appreciation Price
and the Initial Price by a fraction, the numerator of which shall be the
Conversion Rate immediately after such adjustment pursuant to Sections 14(a)(i),
14(a)(ii), 14(a)(iii), 14(a)(iv), 14(a)(v), 14(a)(vi) or 14(a)(vii) or 14(b) and
the denominator of which shall be the Conversion Rate immediately before such
adjustment; provided, that if such adjustment to the Conversion Rate is required
to be made pursuant to the occurrence of any of the events contemplated by
Sections 14(a)(i), 14(a)(ii), 14(a)(iii), 14(a)(iv), 14(a)(v), 14(a)(vi) or
14(a)(vii) or 14(b) during the period taken into consideration for determining
the Applicable Market Value, appropriate and customary adjustments shall be made
to the Conversion Rate.

            (ii)  No adjustment to the Conversion Rate need be made if Holders
      may participate in the transaction that would otherwise give rise to an
      adjustment, so long as the distributed assets or securities the Holders
      would receive upon conversion of the Convertible Preferred Stock, if
      convertible, exchangeable, or exercisable, are convertible, exchangeable
      or exercisable, as applicable, without any loss of rights or privileges
      for a period of at least 45 days following conversion of the Convertible
      Preferred Stock. The applicable Conversion Rate shall not be adjusted:


                                      B-18


                  (A)   upon the issuance of any shares of the Common Stock
      pursuant to any present or future plan providing for the reinvestment of
      dividends or interest payable on the Corporation's securities and the
      investment of additional optional amounts in shares of Common Stock under
      any plan;

                  (B)   upon the issuance of any shares of the Common Stock or
      rights or warrants to purchase those shares pursuant to any present or
      future employee, director or consultant benefit plan or program of or
      assumed by the Corporation or any of its subsidiaries;

                  (C)   upon the issuance of any shares of the Common Stock
      pursuant to any option, warrant, right or exercisable, exchangeable or
      convertible security outstanding as of the date shares of the Convertible
      Preferred Stock were first issued;

                  (D)   for a change in the par value or no par value of the
      Common Stock; or

                  (E)   for accrued, cumulated and unpaid dividends.

            (iii) The Corporation shall have the power to resolve any ambiguity
      or correct any error in this Section 14 and its action in so doing, as
      evidenced by a resolution of the Board, or a duly authorized committee
      thereof, shall be final and conclusive.

      (d)   Notice of Adjustment. Whenever each Fixed Conversion Rate is to be
adjusted in accordance with Section 14(a) or (b), the Corporation shall: (i)
compute each Fixed Conversion Rate in accordance with Section 14(a) or (b) and
prepare and transmit to the Transfer Agent an Officer's Certificate setting
forth each Fixed Conversion Rate, the method of calculation thereof in
reasonable detail, and the facts requiring such adjustment and upon which such
adjustment is based; (ii) as soon as practicable following the occurrence of an
event that requires an adjustment to each Fixed Conversion Rate pursuant to
Section 14(a) or (b) hereof (or if the Corporation is not aware of such
occurrence, as soon as practicable after becoming so aware), provide, or cause
to be provided, a written notice to the Holders of the Convertible Preferred
Stock of the occurrence of such event; and (iii) as soon as practicable
following the determination of each revised Fixed Conversion Rate in accordance
with Section 14(a) or (b) hereof, a statement setting forth in reasonable detail
the method by which the adjustment to each Fixed Conversion Rate was determined
and setting forth each revised Fixed Conversion Rate.

      (e)   Reorganization Events. In the event of:

            (i)   any consolidation or merger of the Corporation with or into
      another Person (other than a merger or consolidation in which the
      Corporation is the continuing corporation and in which the Common Stock
      outstanding immediately prior to the merger or consolidation is not
      exchanged for cash, securities or other property of the Corporation or
      another Person);

            (ii)  any sale, transfer, lease or conveyance to another Person of
      all or substantially all of the property and assets of the Corporation;


                                      B-19


            (iii) any reclassification of Common Stock into securities including
      securities other than Common Stock; or

            (iv)  any statutory exchange of securities of the Corporation with
      another Person (other than in connection with a merger or acquisition)
      (any such event specified in this Section 14(e), a "REORGANIZATION
      EVENT");

each share of Convertible Preferred Stock outstanding immediately prior to such
Reorganization Event shall, after such Reorganization Event, be convertible into
the kind of securities, cash and other property receivable in such
Reorganization Event (without any interest thereon and without any right to
dividends or distribution thereon which have a record date that is prior to the
Conversion Date) per share of Common Stock (the "EXCHANGE PROPERTY") by a holder
of Common Stock that (1) is not a person with which the Corporation consolidated
or into which the Corporation merged or which merged into the Corporation or to
which such sale or transfer was made, as the case may be (any such person, a
"CONSTITUENT PERSON"), or an Affiliate of a Constituent Person to the extent
such Reorganization Event provides for different treatment of Common Stock held
by Affiliates of the Corporation and non-Affiliates, and (2) failed to exercise
his rights of election, if any, as to the kind or amount of securities, cash and
other property receivable upon such Reorganization Event (provided that if the
kind or amount of securities, cash and other property receivable upon such
Reorganization Event is not the same for each share of Common Stock held
immediately prior to such Reorganization Event by other than a Constituent
Person or an Affiliate thereof and in respect of which such rights of election
shall not have been exercised ("NON-ELECTING SHARE"), then, for the purpose of
this Section 14(e) the kind and amount of securities, cash and other property
receivable upon such Reorganization Event by each Non-electing Share shall be
deemed to be the kind and amount so receivable per share by a plurality of the
Non-electing Shares). The amount of Exchange Property receivable upon conversion
of any Convertible Preferred Stock in accordance with Section 7, 8 or 9 hereof
shall be determined based upon the Conversion Rate in effect on such Conversion
Date. The applicable Conversion Rate shall be (x) the Minimum Conversion Rate,
in the case of an Early Conversion Date or a Provisional Conversion Date, and
(y) determined based upon the definition of Conversion Rate set forth in Section
7, in the case of the Mandatory Conversion Date.

      For purposes of this Section 14(e), "APPLICABLE MARKET VALUE" shall be
deemed to refer to the Applicable Market Value of the Exchange Property and such
value shall be determined (A) with respect to any publicly traded securities
that compose all or part of the Exchange Property, based on the Closing Price of
such securities, (B) in the case of any cash that composes all or part of the
Exchange Property, based on the amount of such cash and (C) in the case of any
other property that composes all or part of the Exchange Property, based on the
value of such property, as determined by a nationally recognized independent

Corporation shall send notice thereof by first-class mail, postage prepaid, to
the Holders of the Convertible Preferred Stock.

      (17)  Form. (a) Convertible Preferred Stock shall be issued in the form of

LEGEND"), as set forth on the form of Convertible Preferred Stock certificate
attached hereto as Exhibit A (each, a "GLOBAL PREFERRED SHARE"), which is hereby
incorporated in and expressly made a part of this Certificate of Amendment. The
Global Preferred Share may have notations, legends or endorsements required by
law, stock exchange rules, agreements to which the Corporation is subject, if
any, or usage (provided that any such notation, legend or endorsement is in a
form acceptable to the Corporation). The Global Preferred Share shall be
deposited on behalf of the holders of the Convertible Preferred Stock
represented thereby with the Registrar, at its New York office, as custodian for
DTC or a Depositary, and registered in the name of the Depositary or a nominee
of


                                      B-21


the Depositary, duly executed by the Corporation and countersigned and
registered by the Registrar as hereinafter provided. The aggregate number of
shares represented by each Global Preferred Share may from time to time be
increased or decreased by adjustments made on the records of the Registrar and
the Depositary or its nominee as hereinafter provided. This Section 17(a) shall
apply only to a Global Preferred Share deposited with or on behalf of the
Depositary. The Corporation shall execute and the Registrar shall, in accordance
with this Section, countersign and deliver initially one or more Global
Preferred Shares that (i) shall be registered in the name of Cede & Co. or other
nominee of the Depositary and (ii) shall be delivered by the Registrar to Cede &
Co. or pursuant to instructions received from Cede & Co. or held by the
Registrar as custodian for the Depositary pursuant to an agreement between the
Depositary and the Registrar. Members of, or participants in, the Depositary
("AGENT MEMBERS") shall have no rights under this Certificate with respect to
any Global Preferred Share held on their behalf by the Depositary or by the
Registrar as the custodian of the Depositary or under such Global Preferred
Share, and the Depositary may be treated by the Corporation, the Registrar and
any agent of the Corporation or the Registrar as the absolute owner of such
Global Preferred Share for all purposes whatsoever. Notwithstanding the
foregoing, nothing herein shall prevent the Corporation, the Registrar or any
agent of the Corporation or the Registrar from giving effect to any written
certification, proxy or other authorization furnished by the Depositary or
impair, as between the Depositary and its Agent Members, the operation of
customary practices of the Depositary governing the exercise of the rights of a
holder of a beneficial interest in any Global Preferred Share. The Holder of the
Convertible Preferred Shares may grant proxies or otherwise authorize any Person
to take any action that a Holder is entitled to take pursuant to the Convertible
Preferred Shares, this Certificate of Amendment or the Certificate of
Incorporation. Owners of beneficial interests in Global Preferred Shares shall
not be entitled to receive physical delivery of certificated shares of
Convertible Preferred Stock, unless (x) the Depositary is unwilling or unable to
continue as Depositary for the Global Preferred Share and the Corporation does
not appoint a qualified replacement for the Depositary within 90 days, (y) the
Depositary ceases to be a "clearing agency" registered under the Exchange Act
and the Corporation does not appoint a qualified replacement for the Depositary
within 90 days or (z) the Corporation decides to discontinue the use of
book-entry transfer through the Depositary. In any such case, the Global
Preferred Share shall be exchanged in whole for definitive shares of Convertible
Preferred Stock in registered form, with the same terms and of an equal
aggregate Liquidation Preference. Definitive shares of Convertible Preferred
Stock shall be registered in the name or names of the Person or Person specified
by the Depositary in a written instrument to the Registrar.

      (b)   (i) An Officer shall sign the Global Preferred Share for the
Corporation, in accordance with the Corporation's bylaws and applicable law, by
manual or facsimile signature.

      (ii)  If an Officer whose signature is on a Global Preferred Share no
longer holds that office at the time the Transfer Agent countersigned the Global
Preferred Share, the Global Preferred Share shall be valid nevertheless.

      (iii) A Global Preferred Share shall not be valid until an authorized
signatory of the Transfer Agent manually countersigns Global Preferred Share.
Each Global Preferred Share shall be dated the date of its countersignature.
