 share plus accrued and unpaid dividends to the date of redemption, on June 1 in
 each year beginning with June 1, 1984, 260 shares of Preferred Stock, $6.30
 Series; that shares of Preferred Stock, $6.30 Series, selected for redemption

                                      -2-

 
              (2) Additional shares of the Preferred Stock may, subject to the
         provisions of paragraphs (1) and (6) of subdivision (k) below, be
         issued as additional shares of Preferred Stock of any of the series
         designated above or as shares of one or more other series of Preferred
         Stock, with such distinctive serial designations as shall be set forth
         in the resolution or resolutions from time to time adopted by the Board
         of Directors providing for the issue of such stock or in such other
         instrument providing for the issue of such stock as may be required by
         law; and in any such resolution or resolutions or such other
         instrument, as the case may be, with respect to each particular series
         of the Preferred Stock (other than the series designated above) the
         Board of Directors is hereby expressly authorized to fix, to the extent
         which may be permitted by law,

              (i) the annual dividend rate for the particular series which shall
         not exceed $8 per share, and the date from which dividends on all
         shares of such series issued prior to the record date for the first
         dividend payment date shall be cumulative;

              (ii) the redemption price per share for the particular series
         which (exclusive of accrued and unpaid dividends) shall not exceed $120
         per share;

              (iii) the amount or amounts per share (exclusive of accrued and
         unpaid dividends) for the particular series payable to the holders
         thereof in case of dissolution, liquidation or winding up of the
         affairs of the Corporation, but such amount or amounts shall not exceed
         $120 per share;

              (iv) the terms and conditions, if any, upon which shares of the
         particular series shall be convertible into, or exchangeable for,
         shares of any other class, including the price or prices or the rate or
         rates of conversion or exchange and the terms of adjustment thereof, if
         any;

              (v) the terms and amount of any sinking fund created for the
         purchase or redemption of the particular series of Preferred Stock; and

              (vi) any other characteristics of, and any restrictive or other
         provisions relating to, the shares of each particular series not
         inconsistent with the provisions of the Articles of Incorporation, as
         amended, as the Board of Directors may by law be permitted to fix.

         All shares of Preferred Stock of any one series shall be identical with
         each other in all respects except as to the date from which dividends
         thereon shall be cumulative; and all shares of all series shall be of
         equal rank as to dividends and assets with each other, regardless of
         series, and shall be identical with each other in all other respects
         except as hereinbefore provided.

         (b)  Before any dividends on the Common Stock shall be paid or declared
 or set apart for payment, the holders of the Preferred Stock at the time
 outstanding shall be entitled to receive, but only when and as declared, out of
 any funds legally available for the declaration of

                                      -3-

 
 dividends, cumulative cash dividends at the respective annual rates
 hereinbefore specified with respect to the series of Preferred Stock designated
 above, or, in the case of Preferred Stock of any other series, at the annual
 dividend rate for the particular series theretofore fixed by the Board of
 Directors as hereinbefore provided, payable quarter-yearly on the fifteenth
 days of February, May, August, and November in each year, to stockholders of
 record on the respective dates, not exceeding forty days preceding such
 dividend payment dates, fixed for the purpose by the Board of Directors in
 advance of the payment of each particular dividend.  Such dividends on shares
 of the Preferred Stock shall be cumulative,

              (1) if issued prior to the record date for the first dividend on
         the shares of such series, then, in the case of the series of Preferred
         Stock designated above, from the respective dates hereinbefore
         specified with respect thereto, or, in the case of Preferred Stock of
         any other series, from the date theretofore fixed for the purpose by
         the Board of Directors as hereinbefore provided;

              (2) if issued during the period commencing immediately after a
         record date for a dividend and terminating at the close of the payment
         date for such dividend, then from said last mentioned dividend payment
         date; and

              (3) otherwise from the quarter-yearly dividend payment date next
         preceding the date of issue of such shares;

 so that if dividends on all outstanding shares of the Preferred Stock shall not
 have been paid for all past quarter-yearly dividend periods, and the full
 dividends thereon for the current quarter-yearly dividend period shall not have
 been paid, or declared and set apart for payment, the deficiency shall be fully
 paid or dividends equal thereto declared and set apart for payment, but without
 interest on cumulative dividends, before any dividends shall be declared or any
 distribution made on the Common Stock.  The holders of the Preferred Stock
 shall not be entitled to receive any dividends thereon other than the dividends
 referred to in this subdivision (b).

         (c)  The Corporation, at the option of the Board of Directors, may
 redeem the whole or any part of the Preferred Stock at the time outstanding, or
 the whole or any part of any series thereof, at any time or from time to time,
 by paying, in the case of the series of Preferred Stock designated above, the
 respective redemption prices hereinbefore specified with respect thereto, or,
 in the case of Preferred Stock of any other series, by paying such redemption
 price therefor as shall have been fixed by the Board of Directors as
 hereinbefore provided, together with a sum, in the case of each share so to be
 redeemed, computed at the annual dividend rate for the series of which the
 particular share is a part from the date from which dividends on such share
 became cumulative to the date fixed for such redemption, less the aggregate of
 the dividends theretofore or on such redemption date paid thereon.  Notice of
 every such redemption shall be given by publication, published at least once in
 each of two calendar weeks in a daily newspaper printed in the English language
 and published and of general circulation in the Borough of Manhattan, The City
 of New York, and in a like newspaper published and of general circulation in
 the City of St. Louis, Missouri, the first

                                      -4-

 
 publication to be at least thirty days and not more than sixty days prior to
 the date fixed for such redemption.  At least thirty days' and not more than
 sixty days' previous notice of every such redemption shall also be mailed to
 the holders of record of the Preferred Stock to be redeemed, at their
 respective addresses as the same shall appear on the books of the Corporation;
 but no failure to mail such notice nor any defect therein or in the mailing
 thereof shall affect the validity of the proceedings for the redemption of any
 shares of the Preferred Stock so to be redeemed.  In case of the redemption of
 a part only of any series of the Preferred Stock at the time outstanding, the
 Corporation shall select by lot or in such other manner as the Board of
 Directors may determine, the shares so to be redeemed.  The Board of Directors
 shall have full power and authority, subject to the limitations and provisions
 herein contained, to prescribe the manner in which and the terms and conditions
 upon which the Preferred Stock shall be redeemed from time to time.  If such
 notice of redemption shall have been duly given by publication, and if on or
 before the redemption date specified in such notice all funds necessary for
 such redemption shall have been set aside so as to be available therefor, then,
 notwithstanding that any certificate for the shares of the Preferred Stock so
 called for redemption shall not have been surrendered for redemption, the
 shares represented thereby shall no longer be deemed outstanding in the hands
 of the persons who are the holders thereof immediately preceding such
 redemption, the right of such holders to receive dividends thereon shall cease
 to accrue from and after the date of redemption so fixed, and all rights of
 such holders with respect to such shares of Preferred Stock so called for
 redemption shall forthwith on such redemption date cease and terminate, except
 only the right of such holders to receive the amount payable upon redemption
 thereof, but without interest; provided, however, that the Corporation may,
 after giving the first notice by publication of any such redemption, or giving
 irrevocable instructions therefor, and prior to the redemption date specified
 in such notice, deposit in trust, for the account of the holders of the
 Preferred Stock to be redeemed, with a bank or trust company in good standing,
 organized under the laws of the United States of America or of the State of New
 York, doing business in the Borough of Manhattan, The City of New York, having
 a capital, surplus and undivided profits aggregating at least $5,000,000, all
 funds necessary for such redemption, and thereupon all shares of the Preferred
 Stock with respect to which such deposit shall have been made shall no longer
 be deemed to be outstanding in the hands of such holders, and all rights of
 such holders with respect to such shares of Preferred Stock shall forthwith
 upon such deposit in trust cease and terminate, except only the right of such
 holders to receive the amount payable upon the redemption thereof, but without
 interest.  All or any shares of the Preferred Stock redeemed at any time may,
 in the discretion of the Board of Directors and to the extent permitted by law,
 be reissued or otherwise disposed of at any time or from time to time subject
 to the provisions of these Articles of Incorporation, as amended.

         (d)  In the event of any liquidation, dissolution or winding up of the
 affairs of the Corporation, then before any distribution shall be made to the
 holders of the Common Stock, the holders of shares of the Preferred Stock at
 the time outstanding shall be entitled to be paid in cash, in the case of the
 series of Preferred Stock designated above, the respective amounts hereinbefore
 specified with respect thereto, and, in the case of Preferred Stock of any
 other series, such amount as shall have been fixed by the Board of Directors as
 hereinbefore provided, together with a sum in the case of each such share,
 computed at the annual dividend

                                      -5-

 
 rate for the series of which the particular share is a part from the date from
 which dividends on such shares became cumulative to the date fixed for the
 payment of such distributive amounts, less the aggregate of the dividends
 theretofore or on such date paid thereon.  After such payment to the holders of
 the Preferred Stock, the remaining assets and funds of the Corporation shall be
 divided and distributed among the holders of the Common Stock then outstanding
 according to their respective shares.

         (e)  Unless and until four quarter-yearly dividends payable on the
 Preferred Stock shall be in default, in whole or in part, every stockholder
 shall have one vote for each share of Preferred Stock, and one vote for each
 share of Common Stock, held by him, on all matters, including the election of
 Directors, except as otherwise provided by law or by these Articles of
 Incorporation, as amended.  If and when four quarter-yearly dividends (whether
 or not consecutive) payable on the Preferred Stock shall be in default, in
 whole or in part, every stockholder shall have one vote for each share of
 Preferred Stock, and one vote for each share of Common Stock, held by him, on
 all matters except the election of Directors, and in such case the number of
 Directors of the Corporation shall thereupon, and until such default shall have
 been remedied, be two more than the number specified in and pursuant to Article
 Fifth of the Articles of Incorporation, as amended, the holders of the
 Preferred Stock at the time outstanding, voting separately as a class, shall
 become entitled to elect the two additional members of the Board of Directors,
 and at each annual election of Directors thereafter during the continuance of
 such default the holders of the Preferred Stock, voting separately as a class,
 shall be entitled to elect two members of the Board of Directors and the
 holders of the Common Stock, voting separately as a class, shall be entitled to
 elect the remaining Directors of the Corporation.  However, if and when all
 dividends then in default on the Preferred Stock then outstanding shall
 thereafter be paid (and such dividends shall be declared and paid out of any
 funds legally available therefor as soon as reasonably practicable), the
 Preferred Stock shall thereupon be divested of such special right herein
 provided for to elect such members of the Board of Directors, the voting power
 of the Preferred Stock and the Common Stock shall revert to the status existing
 before the occurrence of such default, and the number of Directors of the
 Corporation shall again be the number specified in and pursuant to Article
 Fifth of the Articles of Incorporation, as amended; but always subject to the
 same provisions for vesting such special rights in the Preferred Stock in case
 of any similar future default or defaults.  A meeting of the holders of the
 Preferred Stock, at which the holders of the Preferred Stock shall vote as a
 class, shall be held at any time after the accrual of such special right to
 elect such two additional members of the Board of Directors, upon notice
 similar to that provided in the By-laws for a special meeting, upon call by the
 holders of not less than 1,000 shares of the Preferred Stock or upon call by
 the Secretary of the Corporation at the request in writing of any holder of
 Preferred Stock addressed to him at the principal office of the Corporation.
 Upon termination of such special right at any time by reason of the payment of
 all accumulated and defaulted dividends on such stock, the terms of office of
 all persons who may have been elected Directors of the Corporation by vote of
 the holders of the Preferred Stock, as a class, pursuant to such special right
 shall forthwith terminate.

         Whenever Directors are elected by the stockholders by classes, pursuant
 to this subdivision (e), in case of any vacancy in the Board of Directors,
 through death, resignation,

                                      -6-

 
 disqualification or other cause, occurring among the Directors elected by the
 holders of the Common Stock, as a class, the remaining Directors elected by the
 vote of the holders of the Common Stock, as a class, by affirmative vote of the
 majority thereof, may elect a successor to hold office for the unexpired term
 of the Director whose place shall be vacant; and in case of any such vacancy in
 the Board of Directors occurring among the Directors elected by the holders of
 the Preferred Stock, as a class, the holders of the Preferred Stock then
 outstanding and entitled to vote may, at a meeting of such holders called in
 the manner provided by this subdivision (e), elect a successor to hold office
 for the unexpired term of the Director whose place shall be vacant.  In all
 other cases any such vacancy shall be filled by the affirmative vote of the
 majority of the remaining Directors, and the Directors so elected shall hold
 office until their successors shall be elected and qualified.

         (f)  In all elections for Directors, each shareholder shall have the
 right to cast as many votes in the aggregate as shall equal the number of
 voting shares held by him multiplied by the number of Directors to be elected,
 and may cast the whole number of votes, either in person or by proxy, for one
 candidate or distribute such votes among two or more candidates; provided,
 however, that in case the Directors are to be elected by particular classes of
 stock as provided in the Articles of Incorporation, as amended, in the event of
 default in the payment of dividends on the Preferred Stock, each holder of the
 particular class of stock shall have the right to cast as many votes in the
 aggregate as shall equal the number of shares of such class held by him
 multiplied by the number of Directors to be elected by such class, and may cast
 the whole number of such votes for one candidate for Director to be elected by
 such class or may distribute such votes among two or more candidates for
 Directors to be elected by such class.

         (g)  Except as otherwise provided by law or by the Articles of
 Incorporation, as amended, the holders of record of a majority of the
 outstanding shares of capital stock of the Corporation entitled to vote at any
 meeting of shareholders, present in person or represented by proxy, shall
 constitute a quorum at such meeting; provided, that in no event shall a quorum
 consist of less than a majority of the outstanding shares entitled to vote, but
 less than such quorum shall have the right successively to adjourn the meeting
 to a specified date not longer than ninety days after such adjournment, without
 notice other than announcement at the meeting.

         (h)  No holder of Preferred Stock shall be entitled as such as a matter
 of right to subscribe for or purchase any part of any new or additional issue
 of stock or securities convertible into stock, of any class whatever, whether
 now or hereafter authorized, and whether issued for cash, property, services or
 otherwise.

         (i)  Upon the issuance for money or other consideration of any shares
 of capital stock of the Corporation or of any securities convertible into
 shares of capital stock of the Corporation, of any class whatever which may be
 authorized from time to time, no holder of shares of Common Stock of the
 Corporation shall be entitled as such as a matter of right to subscribe for,
 purchase or receive any proportionate or other share of the capital stock or
 securities so issued, but all or any portion of such capital stock may be
 disposed of by the

                                      -7-

 
 Corporation, as and when determined by the Board of Directors, free of any such
 rights, whether by offering the same to shareholders or by sale or other
 disposition as the Board of Directors may deem advisable; provided, however,
 that if the Board of Directors shall determine to issue and sell any shares of
 Common Stock (including, for the purposes of this paragraph, any security
 convertible into Common Stock, but excluding shares of such Common Stock and
 securities convertible into such Common Stock theretofore reacquired by the
 Corporation after having been duly issued, or issued to satisfy any conversion
 or option rights theretofore granted by the Corporation) solely for money and
 other than by:

              (1)  a public offering thereof, or

              (2) an offering thereof to or through underwriters or dealers who
         shall agree promptly to make a public offering thereof, or

              (3) The issue thereof in connection with (a) any dividend
         reinvestment, stock purchase or other plan in which the holders of the
         Common, Preferred or Preference Stock or customers of the Corporation
         or of any subsidiary of the Corporation may participate or (b) any
         stock ownership, stock purchase, stock option, stock bonus, savings,
         pension or other plan in connection with which employees or former
         employees (including officers and directors) of the Corporation or any
         subsidiary of the Corporation may purchase or acquire Common Stock (or
         securities of the Corporation convertible into or exchangeable for
         Common Stock) or any trust related to, or any agent acting with respect
         to, any such plan may purchase or acquire Common Stock (or securities
         of the Corporation convertible into or exchangeable for Common Stock)
         on behalf of, or for the account or benefit of, such employees or
         former employees or, in case of any such trust, for the purpose of
         investing the funds of the trust, or

              (4) any other offering thereof which shall have been authorized or
         approved by the affirmative consent (given in writing without a meeting
         or by vote at a meeting duly called for such purpose) of the holders of
         a majority of the shares of Common Stock then outstanding and entitled
         to vote,

 such shares of Common Stock shall first be offered pro rata to the holders of
 record of the then outstanding shares of Common Stock (excluding outstanding
 shares of such Common Stock held for the benefit of holders of scrip
 certificates or other instruments representing fractional interests in a full
 share of such Common Stock) upon terms which, in the judgment of the Board of
 Directors, shall be not less favorable (without deduction of such reasonable
 compensation for the sale, underwriting or purchase of such shares by
 underwriters or dealers as may lawfully be paid by the Corporation) to the
 purchaser than the terms upon which such shares are offered to others than such
 holders of the Common Stock; provided that the Corporation shall not be
 obligated to offer or to issue any fractional interest in a full share of
 Common Stock; and provided further that the time within which such preemptive
 rights shall be exercised may be limited to such time as to the Board of
 Directors may seem proper, not less,

                                      -8-

 
 however, than fourteen days after the mailing of notice that such preemptive
 rights are available and may be exercised.

         (j)  So long as any shares of the Preferred Stock are outstanding, no
 amendment to the Articles of Incorporation which would change the express
 preferences, priorities or character of the Preferred Stock or the rate of
 dividend to be paid thereon in any manner substantially prejudicial to the
 holders thereof shall be made, except as hereinafter in subdivisions (k) and
 (n) provided and except an amendment changing the number of the Board of
 Directors, without the affirmative consent (given in writing without a meeting
 or by vote at a meeting duly called for the purpose) of the holders of at least
 three-fourths of the aggregate number of shares of the Preferred Stock then
 outstanding; but such amendment may be made with such affirmative consent,
 together with such additional vote or consent of stockholders as from time to
 time may be required by law.

         (k)  So long as any of the shares of Preferred Stock are outstanding,
 the Corporation shall not, without the affirmative consent (given in writing
 without a meeting or by vote at a meeting duly called for the purpose) of the
 holders of at least two-thirds of the aggregate number of shares of the
 Preferred Stock then outstanding:

              (1) sell or otherwise dispose of any shares of the Preferred Stock
         or of stock of any other class ranking on a parity with or having any
         preference over the Preferred Stock as to assets or dividends, unless
         the net earnings of the Corporation available for the payment of
         dividends on the Preferred Stock and on all such other classes of
         stock, computed in accordance with good accounting practice, for a
         period of any twelve consecutive calendar months within the fifteen
         calendar months immediately preceding the first day of the month in
         which such additional stock is issued are at least two and one-half
         times the annual dividend requirements on all shares of the Preferred
         Stock and of all other classes of stock ranking on a parity with or
         having any preference over the Preferred Stock as to assets or
         dividends, to be outstanding immediately after such proposed additional
         issue; and, in determining such net earnings available for the payment
         of dividends on the Preferred Stock and on all such other classes of
         stock, any dividend received by the Corporation during such period on
         stock of any subsidiary of the Corporation in excess of the net
         earnings of such subsidiary for such period available therefor,
         computed in accordance with good accounting practice, shall be included
         only to the extent of such net earnings of such subsidiary; or

              (2) create any class of stock which shall be preferred as to
         dividends or assets over the Preferred Stock; or

              (3) increase the authorized number of shares of the Preferred
         Stock; or

              (4) reclassify outstanding shares of stock of any class ranking
         junior to the Preferred Stock as to assets or dividends, wholly or
         partially, into shares of stock of

                                      -9-

 
         any class ranking on a parity with or having any preference over the
         Preferred Stock as to assets or dividends; or

              (5) make any distribution out of capital or capital surplus (other
         than dividends payable in stock ranking junior to the Preferred Stock
         as to assets and dividends) to holders of stock of the Corporation
         ranking junior to the Preferred Stock as to assets or dividends; or

              (6) issue any shares of the Preferred Stock or any other stock
         ranking on a parity with or having any preference over the Preferred
         Stock as to assets or dividends, if the stated capital to be
         represented by the Preferred Stock and such other stock outstanding
         immediately after such issue would exceed the stated capital to be
         represented by shares of stock to be then outstanding ranking junior to
         the Preferred Stock as to assets and dividends, increased by the amount
         of any capital surplus or reduced by the amount of any deficit.  For
         the purpose of this subdivision (6), stated capital represented by any
         preferred stock having a par value shall be the par value thereof, and
         stated capital represented by any preferred stock without par value
         shall be the amount of stated capital fixed by the Board of Directors
         with respect thereto at the time of issue thereof, or the amount
         payable to the holders thereof (exclusive of accrued and unpaid
         dividends) in preference to the Common Stock upon involuntary
         liquidation, dissolution or winding up of the affairs of the
         Corporation, whichever is greater;

 but any such action requiring such affirmative consent of the holders of the
 Preferred Stock, as provided in this subdivision (k), may be taken with such
 vote or consent of stockholders as may at the time be required by law, but with
 at least the affirmative consent (given in writing without a meeting or by vote
 at a meeting duly called for the purpose) of the holders of two-thirds of the
 aggregate number of shares of Preferred Stock then outstanding.  Stock shall
 not be considered to be outstanding for any of the purposes of this subdivision
 (k) or of subdivision (j) above, if the Board of Directors shall have
 determined to redeem such stock and if the first publication of notice of
 redemption shall have been made, or irrevocable instructions given therefor,
 and all funds necessary for such redemption shall have been deposited in trust
 for such purpose.

         (l)  No amendment to the Articles of Incorporation which would change
 the provisions of the foregoing subdivisions (f), (g) or (i) in any manner
 substantially prejudicial to the holders of any class of stock, shall be made
 without the affirmative consent (given in writing without a meeting or by vote
 at a meeting duly called for such purpose) of the holders of at least two-
 thirds of the aggregate number of shares of capital stock of the Corporation
 then outstanding and entitled to vote; but such amendment may be made with such
 affirmative consent, together with such additional vote or consent of
 shareholders as from time to time may be required by law.

         (m)  No amendment to the Articles of Incorporation providing for the
 creation or increase of Preferred Stock of any class shall be made without the
 affirmative consent (given in

                                      -10-

 
 writing without a meeting or by vote at a meeting duly called for such purpose)
 of the holders of at least a majority of the aggregate number of shares of
 Common Stock of the Corporation then outstanding; but such amendment may be
 made with such affirmative consent, together with such additional vote or
 consent of holders of Preferred Stock of the Corporation as shall at the time
 be required by the Articles of Incorporation, as amended.

         (n)  Subject to the provisions of subdivisions (j), (k), (l) and (m)
 hereof, the Corporation reserves the right to amend, alter, change or repeal,
 to the extent now or hereafter permitted by law, any provision in its Articles
 of Incorporation, as amended, (including the authorizing of preferred stock
 junior to the Preferred Stock as to dividends and assets and the changing of
 any authorized but unissued shares of the Preferred Stock to shares of another
 class or classes of preferred stock ranking on a parity with the Preferred
 Stock as to assets and dividends but which may have different dividend rates,
 redemption prices and other terms and provisions as may at the time be
 permitted by law) with such vote or consent of stockholders as from time to
 time may be required by law, and all rights herein conferred upon the
 shareholders are granted subject to this reservation.

         (o)  Subject to the provisions of subdivision (k) hereof, the
 Corporation may issue and dispose of its authorized but unissued shares without
 par value, from time to time, for such consideration as may from time to time
 be prescribed by the Board of Directors, and authority is hereby expressly
 conferred on the Board of Directors so to fix such consideration.  The Board of
 Directors is also hereby expressly authorized to determine, at or before the
 time of issue thereof, what part of the consideration which shall be received
 by the Corporation upon the issue from time to time of shares of its capital
 stock without par value shall be capital, and, in the absence of any such
 determination, the entire consideration received for any particular shares
 shall be capital.  Any and all shares without par value issued for the
 consideration so fixed shall be deemed fully paid and be non-assessable, and
 the holder of such shares shall not be liable thereon to the Corporation or its
 creditors.

         (p)  The Preference Stock shall have, or be subject to, as the case may
 be, the following preferences, rights, privileges and restrictions:

         Manner of Issue - Series - The Board of Directors is empowered to cause
 the Preference Stock to be issued from time to time as shares of one or more
 series of Preference Stock, and in the resolution or resolutions providing for
 the issue of each particular series, before issuance, the Board of Directors is
 expressly authorized to fix:

              (1) the distinctive serial designation of the shares of such
         series and the number of shares which shall constitute such series;

              (2) the annual dividend rate for the particular series, the dates
         of payment of dividends on shares of such series and the dates from
         which they are cumulative;

              (3) the redemption price per share and the terms of redemption for
         the shares of a particular series;

                                      -11-

 
         (4) the amount or amounts per share (exclusive of accrued and unpaid
         dividends) for the particular series payable to the holders thereof in
         case of dissolution, liquidation or winding up of the affairs of the
         Corporation;

              (5) the terms and conditions, if any, upon which shares of the
         particular series shall be convertible into, or exchangeable for,
         shares of any stock of junior rank, with respect to dividends and
         assets, including the price or prices or the rate or rates of
         conversion or exchange and the terms of adjustment thereof, if any;

              (6) the terms and amount of any sinking fund created for the
         purchase or redemption of the shares of any particular series; and

              (7) any other characteristics of, and any restrictive or other
         provisions relating to, the shares of each particular series not
         inconsistent with the provisions of the Articles of Incorporation, as
         amended, as the Board of Directors may by law be permitted to fix.

 All shares of Preference Stock shall be of junior rank, with respect to
 dividends and assets, to all shares of Preferred Stock and of senior rank in
 such respects to all shares of Common Stock.  All shares of Preference Stock of
 any one series shall be identical with each other in all respects except, in
 the event portions of the shares of a single series are issued at different
 times, the date from which dividends thereon shall be cumulative; and all
 shares of all series shall be of equal rank as to dividends and assets with
 each other, regardless of series, and shall be identical with each other in all
 respects except as hereinabove provided.

         Dividends - Dividends on Preference Stock of any series shall be
 payable at annual rates and on dates fixed by the Board of Directors at the
 time of the creation of such series, payable quarter-yearly on such dates as
 shall be fixed for such payments by the Board of Directors.  The right of
 holders of Preference Stock to receive dividends shall be subject to the
 dividend and sinking fund provisions of the Preferred Stock.  Dividends on the
 Preference Stock shall be cumulative, and no dividends shall be declared or
 paid, or any distribution made, on Common Stock, other than a dividend payable
 in Common Stock, unless and until full dividends on the outstanding Preference
 Stock shall have been paid, or declared and a sum sufficient for the payment
 thereof set aside, with respect to all past dividend periods and the current
 dividend period.  Dividends on shares of any series of Preference Stock shall
 accrue from and be cumulative from such date as may be fixed by the Board of
 Directors at the time of the creation of such series, except that dividends on
 shares of Preference Stock of any series, which are issued after the initial
 issue of shares of such series, shall accrue from and be cumulative from such
 date as may be fixed by the Board of Directors at the time of issuance of such
 additional shares.

         Redemption - If so provided by the Board of Directors upon the creation
 of any series of Preference Stock, the Corporation, at the option of the Board
 of Directors, or in accordance with the requirements of any sinking fund for
 the Preference Stock or any series thereof, may redeem the whole or any part of
 the Preference Stock at any time outstanding, or

                                      -12-

 
 the whole or any part of any series thereof, at such time or times and from
 time to time as may be determined by the Board of Directors and at such
 redemption price or prices as may have been fixed by the Board of Directors at
 the time of the creation of the shares so to be redeemed, together with an
 amount equal to all unpaid dividends accrued thereon to the date fixed for such
 redemption, and otherwise upon the terms and conditions fixed by the Board of
 Directors for any such redemption; provided, however, that no redemption of any
 Preference Stock shall be effected unless (1) full dividends on all outstanding
 shares of Preferred Stock and Preference Stock for all past dividend periods
 shall have been paid, or declared and a sufficient sum set apart for the
 payment thereof, and (2) all obligations of the Corporation, if any, with
 respect to the redemption or purchase of shares of Preferred Stock and
 Preference Stock in accordance with the requirements of any sinking fund have
 been met.

         Liquidation, Dissolution and Winding Up of the Affairs of the
 Corporation - In the event of any liquidation, dissolution or winding up of the
 affairs of the Corporation, whether voluntary or involuntary, but only after
 full payment has been made to the holders of the Preferred Stock of all amounts
 to which they are entitled by these Articles of Incorporation, as amended, or a
 sufficient sum set apart for such payment, the holders of shares of each series
 of Preference Stock then outstanding shall be entitled to receive out of the
 assets of the Corporation, before any distribution or payment shall be made to
 the holders of the Common Stock, the amount fixed by the Board of Directors in
 creating such series, plus an amount equal to all unpaid dividends accrued
 thereon to the date fixed for such payment to the holders of Preference Stock.

         Voting Rights - Except as otherwise provided in these Articles of
 Incorporation, as amended, each holder of Preference Stock shall be entitled at
 all meetings of shareholders of the Corporation to one vote for each share of
 such stock held by him; and the holders of Preference Stock shall vote together
 with the holders of the Preferred Stock and the Common Stock as a single class,
 except in those instances where these Articles of Incorporation, as amended,
 grant to the holders of Preferred Stock or Common Stock the right to vote as a
 separate class.  The voting rights of the holders of Preference Stock in an
 election of directors shall be identical with the voting rights of the holders
 of Common Stock in such election, as set forth in these Articles of
 Incorporation, as amended, and the provision for filling vacancies in the Board
 of Directors that are by said amended Articles applicable to holders of the
 Common Stock shall be equally applicable to holders of the Preference Stock.

         Whenever four quarter-yearly dividends payable on the Preference Stock
 shall be in default, and during the continuance of such default, the Common
 Stock and the Preferred Stock, voting together as a single class, shall be
 entitled to elect the same number of directors as was authorized by the
 Articles of Incorporation immediately prior to such default, and the Preference
 Stock, as a class, shall be entitled to elect two additional directors.

         Notwithstanding any other provision in those Articles of Incorporation,
 as amended, the affirmative approval of the holders of at least two-thirds of
 the Preference Stock of all series thereof then outstanding present and voting
 at a meeting, voting as a single class without regard to series, shall be
 required for any amendment of these Articles of Incorporation, as

                                      -13-

 
 amended, altering adversely any existing provision of the Preference Stock or
 for an increase in the authorized amount of the Preference Stock or the
 creation, or an increase in the authorized amount of any class of stock
 ranking, as to dividends and assets, on a parity with or prior to the
 Preference Stock.

         Preemptive Rights - No holder of shares of any series of the Preference
 Stock shall, as such, have any preemptive or preferential right to subscribe to
 or purchase shares of any class or series of stock of the Corporation, now or
 hereafter authorized, or any securities convertible into, or warrants or other
 evidences of optional rights to purchase, or subscribe to, shares of any class
 or series of stock of the Corporation, now or hereafter authorized.
