                           CONVERTIBLE PREFERRED STOCK

     Dividends. The holders of Convertible Preferred Stock shall be entitled to
receive, when and as declared by the Board of Directors, out of funds legally
available for the payment of dividends, cumulative cash dividends from the last
day of the month of March, June, September or December next preceding the date
on which such stock is issued, at the rate of $1.20 per share per annum in the
case of the $1.20 Convertible Preference Stock, and no more, payable quarterly
on the first day of the months of January, April, July and October in the case
of the $1.20 Convertible Preference Stock, but in no event shall such dividends
accrue for any period prior to January 1, 1966 in the case of the $1.20
Convertible Preference Stock. In no event, so long as any Convertible Preferred
Stock shall remain outstanding, shall any dividend whatsoever, other than a
dividend payable in shares of junior stock, be declared or paid upon, nor shall
any distribution be made upon, any junior stock, nor shall any shares of junior
stock be purchased or redeemed by the Corporation otherwise than in connection
with a refunding of junior stock through the issue of other junior stock, nor
shall any moneys be paid to or made available for a sinking fund for the
purchase or redemption of any junior stock, unless in each instance dividends on
all outstanding shares of the Convertible Preferred Stock for all past dividend
periods shall have been paid and the dividend on all outstanding shares of the
Convertible Preferred Stock for the then current quarterly dividend period shall
have been paid or declared and sufficient funds are available for the payment
thereof. Subject to the foregoing, dividends may be paid upon junior stock as
and when declared by the Board of Directors out of any funds of the Corporation
legally available therefor.

     Redemption. The Corporation, at the option of the Board of Directors, at
any time after January 1, 1972 in the case of the $1.20 Convertible Preference
Stock, may redeem, in whole, or from time to time in part, the Convertible
Preferred Stock, upon notice given as hereinafter provided, by paying for each
share in cash the sum of Forty Dollars ($40) in the case of the $1.20
Convertible Preference Stock, plus in each case an amount equal to dividends
accrued thereon to the date fixed for redemption. In case of the redemption of
less than all of the outstanding shares of Convertible Preferred Stock, the
shares to be redeemed shall be selected by lot or pro rata in such manner as the
Board of Directors shall determine from among the outstanding shares of
Convertible Preferred Stock. Not less than thirty (30) days' prior written
notice shall be given by mail, postage prepaid, to the holders of record of the
Convertible Preferred Stock to be redeemed, such notice to contain a statement
of or reference to the conversion right set forth in the paragraph entitled
'Conversion' and to be addressed to each such shareholder at his post office
address as shown by the records of the Corporation.

     If such notice of redemption shall have been duly given, and if on or
before the redemption date specified in such notice the funds necessary for such
redemption shall have been set aside so as to be and continue to be available
therefor, then, notwithstanding that any certificate for shares so called for
redemption shall not have been surrendered for cancellation, from and after such
redemption date, the

                                      -17-
   4
shares so called for redemption shall no longer be deemed outstanding, the
dividends thereon shall cease to accrue, and all rights with respect to shares
so called for redemption, including the rights, if any, to receive notices and
to vote, shall forthwith on such redemption date cease and terminate, except
only the right of the holders thereof to receive the amount payable upon
redemption thereof, without interest; provided, however, that if such notice of
redemption shall have been duly given, and if on or before the redemption date
specified in such notice, there shall have been deposited with a bank or trust
company in the Borough of Manhattan, City and State of New York, having capital,
surplus and undivided profits of at least Five Million Dollars ($5,000,000) in
trust for the account of the holders of the shares so called for redemption
which shall not have been surrendered for conversion pursuant to the paragraph
entitled 'Conversion', the funds necessary for such redemption, then upon the
making of such deposit in trust, the shares with respect to which such deposit
shall have been made shall no longer be deemed to be outstanding, and all rights
with respect to such shares, including the rights, if any, to receive notices
and to vote, shall forthwith cease and terminate, except only the right of the
holders thereof to receive, out of the funds so deposited in trust, from and
after the date of such deposit, the amount payable upon the redemption thereof,
without interest, or to convert their shares up to the close of business on the
third full business day prior to the date fixed for redemption, into Common
Stock pursuant to the paragraph entitled 'Conversion'. Any funds so deposited
which shall not be required for such redemption because of the exercise of any
right of conversion or exchange or otherwise subsequent to the date of such
deposit shall be returned to the Corporation forthwith. Any interest accrued on
any funds so deposited shall belong to the Corporation and be paid to it from
time to time. Any other funds so set aside or deposited by the Corporation and
unclaimed at the end of six years from the date fixed for such redemption shall
be repaid to the Corporation, upon its request, after which repayment the
holders of such shares so called for redemption shall look only to the
Corporation for the payment of the amount payable upon the redemption thereof.
Subject to the provisions hereof the Board of Directors shall have authority to
prescribe the manner in which the Convertible Preferred Stock shall be redeemed
from time to time. All shares of Convertible Preferred Stock so redeemed shall
be permanently retired and shall not under any circumstances be reissued; and
the Corporation may from time to time take such appropriate corporate action as
may be necessary to reduce the authorized Convertible Preferred Stock
accordingly.

     Liquidation. Upon any liquidation, dissolution or winding up of the
Corporation, and after the holders of the Series Preferred Stock shall have been
paid in full the amounts to which they shall be entitled. or after an amount
sufficient to pay the aggregate amount to which the holders of the Series
Preferred Stock shall be entitled shall have been deposited with a bank or trust
company in the Borough of Manhattan, City and State of New York, having capital,
surplus and undivided profits of at least Five Million Dollars ($5,000,000), in
trust for the account of the holders of the Series Preferred Stock, the
remaining net assets of the Corporation shall be distributed pro rata to the
holders of the $1.20 Convertible Preference Stock and the Common Stock in
proportion to the number of shares of each such class at the time outstanding.
Written notice of such liquidation, dissolution or winding up, stating a payment
date and the place where said sums shall be payable and containing a statement
of or reference to the conversion right set forth in the paragraph entitled
'Conversion', shall be given by mail, postage prepaid, not less than thirty (30)
days prior to the payment date stated therein, to the holders of record of the
Convertible Preferred Stock, such notice to be addressed to each such
shareholder at his post office address as shown by the records of the
Corporation. Neither the consolidation or merger of the Corporation into or with
any other corporation or corporations, nor the sale or transfer by the
Corporation of all or any part of its assets, nor the reduction of the capital
stock of the Corporation, shall be deemed to be a liquidation, dissolution or
winding up of the Corporation within the meaning of any of the provisions of
this paragraph.

                                      -18-

     Conversion. (1) Any share or shares of Convertible Preferred Stock may be
converted, at the option of the holder thereof, in the manner hereinafter
provided, into full-paid and non-assessable shares of Common Stock of the
Corporation; provided, however, that (a) as to any share of Convertible
Preferred Stock which shall have been called for redemption, the right of
conversion shall terminate at the close of business on the third full business
day prior to the date fixed for redemption, and (b) on any liquidation of the
Corporation the right of conversion shall terminate at the close of business on
the third full business day before the date fixed for the initial payment of
distributable amounts on the Convertible Preferred Stock.

     (2)[Deleted]

     (3)The conversion rate with respect to the $1.20 Convertible Preference
Stock shall be .825 of a share of Common Stock for each one share of such $1.20
Convertible Preference Stock surrendered for conversion, subject to adjustment
as hereinafter provided.

           (a)In case at any time shares of Common Stock outstanding shall be
     combined into a lesser number of shares, whether by reclassification,
     recapitalization, reduction of capital stock or otherwise, the conversion
     rate shall be propor tionately decreased,

           (b)In case the shares of Common Stock at any time outstanding shall,
     at any time after December 31, 1965, be subdivided, by reclassification,
     recapitalization or otherwise (including the issuance of shares of Common
     Stock as a dividend on the Common Stock), into a greater number of shares
     without the actual receipt by the Corporation of any consideration for the
     additional number of shares so issued, the conversion rate shall be
     proportionately increased.

     (4) Any conversion rate determined or adjusted as herein provided shall
remain in effect until further adjustment as required herein. Upon each
adjustment of the conversion rate a written instrument signed by an officer of
the Corporation, setting forth such adjustment and the computation and a summary
of the facts upon which it is based, shall forthwith be filed with the principal
transfer agent for the Convertible Preferred Stock of the class or classes
affected and made available for inspection by the shareholders, and any
adjustment so evidenced, made in good faith, shall be binding upon all
shareholders and upon the Corporation. Upon any conversion fractional shares
shall not be issued but any fractions shall be adjusted in cash, unless the
Board of Directors shall determine to adjust them by the issue of fractional
scrip certificates or in some other manner. Upon any conversion, no adjustment
shall be made for dividends on the Convertible Preferred Stock surrendered for
conversion or on the Common Stock delivered The Corporation shall pay all issue
taxes, if any, incurred in respect of the issue of the Common Stock on
conversion, provided, however, that the Corporation shall not be required to pay
any transfer or other taxes incurred by reason of the issuance of such Common
Stock in names other than those in which the Convertible Preferred Stock
surrendered for conversion may stand.

     (5) Any conversion of Convertible Preferred Stock into shares of Common
Stock shall be made by the surrender to the Corporation, at the office of any
transfer agent for the Convertible Preferred Stock, of the certificate or
certificates representing the share or shares of Convertible Preferred Stock to
be converted, duly endorsed or assigned (unless such endorsement or assignment
be waived by the Corporation), together with a written request for conversion.

                                      -19-
   6
           (6)All shares of Convertible Preferred Stock which shall have been
     surrendered for conversion as herein provided shall no longer be deemed to
     be outstanding and all rights with respect to such shares, including the
     rights, if any, to receive notices and to vote, shall forthwith cease and
     terminate except only the right of the holders thereof to receive Common
     Stock in exchange therefor. Any shares of Convertible Preferred Stock so
     converted shall be permanently retired, shall no longer be deemed
     outstanding and shall not under any circumstances be reissued and the
     Corporation may from time to time take such appropriate corporate action as
     may be necessary to reduce the authorized Convertible Preferred Stock
     accordingly.

           (7)In case of any reclassification or change of outstanding shares of
     Common Stock of the class issuable upon conversion of the shares of
     Convertible Preferred Stock, or in case of any consolidation or merger of
     the Corporation with or into another corporation, or in case of any sale or
     conveyance to another corporation of the property of the Corporation as an
     entirety or substantially as an entirety, the holder of each share of
     Convertible Preferred Stock then outstanding shall have the right
     thereafter to convert such share into the kind and amount of shares of
     stock and other securities and property receivable, upon such
     reclassification, change, consolidation, merger, sale or conveyance, by a
     holder of the number of shares of Common Stock (whole or fractional) of the
     Corporation into which such share of Convertible Preferred Stock might have
     been converted immediately prior to such reclassification, change,
     consolidation, merger, sale or conveyance. In the event of any such
     consolidation, merger, sale or conveyance (a) effective provision shall be
     made, in the charter of the continuing or successor Corporation or
     otherwise, so that in the opinion of the Board of Directors of the
     Corporation, the provisions set forth herein for the protection of the
     conversion rights of the Convertible Preferred Stock shall thereafter be
     applicable, as nearly as reasonably may be, to any such other shares of
     stock and other securities and property deliverable upon conversion of the
     Convertible Preferred Stock remaining outstanding or other Convertible
     Preferred Stock received by the holders in place thereof, and (b) any such
     continuing or successor Corporation shall expressly assume the obligation
     to deliver, upon the exercise of the conversion privilege, such shares,
     securities or property as the holders of shares of the Convertible
     Preferred Stock remaining outstanding, or other convertible preferred stock
     received by the holders in place thereof, shall be entitled to receive
     pursuant to the provisions hereof, and to make provision for the protection
     of the conversion right as above provided. In case securities or property
     other than Common Stock shall be issuable or deliverable upon conversion as
     aforesaid, then all references in this paragraph entitled 'Conversion'
     shall be deemed to apply so far as appropriate and as nearly as may be, to
     such other securities or property.

          (8)A number of shares of authorized Common Stock sufficient to provide
     for the conversion of the Convertible Preferred Stock outstanding upon the
     basis hereinbefore provided shall at all times be reserved for such
     conversion. If the Corporation shall propose to make any change in its
     capital structure which would change the number of shares of Common Stock
     into which each share of the Convertible Preferred Stock shall be
     convertible as herein provided, the Corporation shall at the same time also
     make proper provision so that thereafter there shall be a sufficient number
     of shares of Common Stock authorized and reserved for conversion of the
     outstanding Convertible Preferred Stock on the new basis.

     Voting Rights. Each holder of Convertible Preferred Stock shall be entitled
to one vote for each share held and, except as otherwise by law provided or as
provided with respect to any series of the Series Preferred Stocks, the
Convertible Preferred Stock, the shares of any series of the Series Preferred
Stock having general voting rights and the Common Stock of the Corporation shall
vote together as one class.

                                      -20-
   7
     Denial of Preemptive Rights. No holder of the Convertible Preferred Stock
shall be entitled, as such, as a matter of right, to subscribe for or to
purchase any part of any new or additional issue of stock of any class
whatsoever or of securities convertible into stock of any class whatsoever,
whether now or hereafter authorized, or whether issued for cash or other
consideration, or by way of dividend. Notwithstanding the foregoing, or the
provisions of Section E of this Article III, in the event that the Corporation
grants to the holders of its Common Stock generally rights to subscribe for or
purchase any stock or securities, the Corporation shall also grant to the
holders of the Convertible Preferred Stock rights to subscribe for or purchase,
on the same terms as such stock or securities are offered to the holders of the
Common Stock, an amount of such stock or securities equal to the amount which
they would be entitled to purchase if the Convertible Preferred Stock had been
converted into Common Stock at the then applicable conversion rate.

                                       B.

time as herein provided in one or more series. The designations, relative
rights, preferences and limitations of the Series Preferred Stock, and
particularly of the shares of each series thereof, may, to the extent permitted
by law, be similar to or differ from those of any other series. The Board of
Directors of the Corporation is hereby expressly granted authority, subject to
the provisions of this Article III, to fix from time to time before issuance
thereof the number of shares in each series of such class and all designations,
relative rights, preferences and limitations of the shares in each such series,
including, but without limiting the generality of the foregoing, the following:

          distinctive designation thereof;

               (ii)The dividend rate on the shares of such series, whether or
          not dividends on the shares shall be cumulative, and the date or
          dates, if any, from which dividends thereon shall be cumulative;

               (iii)Whether or not the shares of such series shall be
          redeemable, and, if redeemable, the date or dates upon or after which
          they shall be redeemable, the amount per share payable thereon in the
          case of the redemption thereof, which amount may vary at different
          redemption dates or otherwise as permitted by law;

               (iv)Whether or not the shares of such series shall be subject to
          the operation of a retirement or sinking fund to be applied to the
          purchase or redemption of such shares for retirement and, if such
          retirement or sinking fund be established, the amount thereof, and the
          terms and provisions relative to the operation thereof;

               (v)The right, if any, of holders of shares of such series to
          convert the same into or exchange the same for Common Stock, and the
          terms and conditions of such conversion or exchange, as well as
          provisions for adjustment of the conversion rate in such events as the
          Board of Directors shall determine;

               (vi)The amount per share payable on the shares of such series
          upon the voluntary and involuntary liquidation, dissolution or winding
          up of the Corporation;

                                      -21-
   8
               (vii)Whether the holders of shares of such series shall have
          voting power, full or limited, in addition to the voting powers
          provided by law, and in case additional voting powers are accorded to
          fix the extent thereof; and

               (viii)Generally to fix the other rights and privileges and any
          qualifications, limitations or restrictions of such rights and
          privileges of such series, provided, however, that no such rights,
          privileges, qualifications, limitations or restrictions shall be in
          conflict with the Certificate of Incorporation of the Corporation or
          with the resolution or resolutions adopted by the Board of Directors
          providing for the issue of any series of which there are shares then
          outstanding.

          All shares of Series Preferred Stock of the same series shall be
     identical in all respects, except that shares of any one series issued at
     different times may differ as to dates, if any, from which dividends
     thereon may accumulate. All shares of Series Preferred Stock of all series
     shall be of equal rank (ranking equally as to dividends with the $1.20
     Convertible Preference Stock) and shall be identical in all respects except
     that to the extent not otherwise limited in this Article III any series may
     differ from any other series with respect to any one or more of the
     designations, relative rights, preferences and limitations described or
     referred to in subparagraphs (i) to (viii) inclusive above.

          2. Dividends. The holders of shares of the Series Preferred Stock of
     each series shall be entitled to receive, when and as declared by the Board
     of Directors, out of funds legally available for the payment of dividends,
     dividends at the rates fixed by the Board of Directors for such series, and
     no more, before any dividends, other than dividends payable in Common
     Stock, shall be declared and paid, or set apart for payment, on the Common
     Stock with respect to the same dividend period.

          All shares of Series Preferred Stock of all series shall be of equal
     rank, preference and priority as to dividends irrespective of whether or
     not the rates of dividends to which the same shall be entitled shall be the
     same and when the stated dividends are not paid in full, the shares of all
     series of the Series Preferred Stock shall share ratably in the payment
     thereof in accordance with the sums which would be payable on such shares
     if all dividends were paid in full, provided, however, that any two or more
     series of the Series Preferred Stock may differ from each other as to the
     existence and extent of the right to cumulative dividends, as aforesaid.

          3. Voting Rights. Except as otherwise specifically provided in the
     certificate filed pursuant to law with respect to any series of the Series
     Preferred Stock, or as otherwise provided by law, the Series Preferred
     Stock shall not have any right to vote for the election of directors or for
     any other purpose and the Convertible Preferred Stock and the Common Stock
     shall have the exclusive right to vote for the election of directors and
     for all other purposes.

          4. Liquidation. In the event of any liquidation, dissolution or
     winding up of the Corporation, whether voluntary or involuntary, each
     series of the Series Preferred Stock shall have preference and priority
     over the $1.20 Convertible Preference Stock and the Common Stock for
     payment of the amount to which each outstanding series of the Series

Stock shall be entitled to be paid in full such amounts, or have a sum
sufficient for the payment in full set aside, before any payments shall be made
to the holders of the $1.20 Convertible Preference Stock or the Common Stock.
If, upon liquidation, dissolution or winding up of the Corporation, the assets
of the Corporation or proceeds thereof, distributable among the holders of the
shares of all series of the Series Preferred Stock shall be insufficient to pay
in full the preferential amounts aforesaid, then such assets, or the proceeds
thereof, shall be distributed among such holders ratably in accordance with the
respective amounts which would be payable if all amounts payable thereon were
paid in full. After the payment to the holders of the Series Preferred Stock of
all such amounts to which they are entitled, as above provided, the remaining
assets and funds of the Corporation shall be divided and paid to the holders of
the $1.20 Convertible Preference Stock and the Common Stock. Neither the
consolidation or merger of the Corporation into or with any other corporation or
corporations, nor the sale or transfer by the Corporation of all or any part of
its assets, nor the reduction of the capital stock of the Corporation, shall be
deemed to be a liquidation, dissolution or winding up of the Corporation within
the meaning of any of the provisions of this paragraph.

     series shall be made redeemable as provided in clause (iii) of paragraph 1

     Board of Directors, may redeem at any time or times, and from time to time,
     all or any part of any one or more series of Series Preferred Stock
     outstanding, upon notice and terms as may be specifically provided in the
     certificate filed pursuant to law with respect to the series, by paying for
     each share the then applicable redemption price fixed by the Board of
     Directors plus an amount equal to accrued and unpaid dividends to the date
     fixed for redemption.

                                       C.

          Dividends.Subject to all of the rights of the Convertible Preferred
     Stock and the rights of the Series Preferred Stock, dividends may be paid
     upon the Common Stock as and when declared by the Board of Directors out of
     any funds legally available for the payment of dividends.

          Liquidation. Upon any liquidation, dissolution or winding up of the
     Corporation, whether voluntary or involuntary and after the holders of the
     Series Preferred Stock shall have been paid in full amounts to which they
     respectively shall be entitled, or an amount sufficient to pay the
     aggregate amount to which the holders of the Series Preferred Stock shall
     be entitled shall have been deposited with a bank or trust company having
     its principal office in the Borough of Manhattan, The City of New York, and
     having capital, surplus and undivided profits of at least Five Million
     Dollars ($5,000,000), as a trust fund for the benefit of the holders of the
     Series Preferred Stock, the remaining net assets of the Corporation shall
     be distributed pro rata to the holders of the $1.20 Convertible Preference
     Stock and the Common stock in proportion to the number of shares of each
     such class at the time outstanding.

          Voting Rights. Each holder of Common Stock of the Corporation shall be
     entitled to one vote for each share held and, except as otherwise by law
     provided or as provided with respect to any series of the Series Preferred
     Stock, the Convertible Preferred Stock, the shares of any series of Series
     Preferred Stock having general voting rights and the Common Stock of the
     Corporation shall vote together as one class.

                               CERTAIN DEFINITIONS

          For the purposes of this Article III the following terms shall be
     deemed to have the meanings specified below:

          The terms "dividends accrued" and "an amount equal to dividends
     accrued," whenever used herein with reference to shares of Convertible
     Preferred stock, shall mean an amount per share computed at the annual rate
     set forth in the paragraph entitled "Dividends" under "Convertible
     Preferred Stock" above, or a quarterly rate equal to one-fourth (1/4) of
     such annual rate, from and including the dividend payment date to which the
     dividends on such share have been paid, to but not including the date to
     which dividends are to be accrued. The amount per share for less than a
     full quarterly dividend period shall be computed by (a) assuming that there
     are 90 days in such full quarterly dividend period, (b) determining the
     number of days from and including the next preceding dividend payment date,
     to but not including the date to which the dividend is to be accrued, and
     (c) multiplying the applicable quarterly dividend rate by a fraction, the
     numerator of which shall be the number of days of the accrual as in (b) and
     the denominator of which shall be 90, but in no event shall such accrual be
     more than such applicable quarterly dividend rate.

          The term "junior stock" shall mean the Common Stock and any other
     stock ranking junior to the Convertible Preferred Stock in respect of the
     payment of dividends or of payment in liquidation, or both, in accordance
     with the subject matter of the context, provided that the $1.20 Convertible
     Preference Stock shall not be deemed to be "junior stock" for the purposes
     of the paragraph entitled "Dividends" under "Convertible Preferred Stock"
     above.

                                       E.

                           WAIVER OF PREEMPTIVE RIGHTS

          No holder of Convertible Preferred Stock, Series Preferred Stock or
     Common Stock shall be entitled as of right to purchase or subscribe for any
     part of any unissued stock of any class or of any additional Convertible
     Preferred Stock, Series Preferred Stock or Common Stock to be issued by
     reason of any increase of the authorized capital stock of the Corporation
     of any class, or of bonds, certificates of indebtedness, debentures or
     other securities convertible into stock of the Corporation, but any such
     unissued stock or such additional authorized issue of new stock or of other
     securities convertible into stock may be issued and disposed of pursuant to
     resolution of the Board of Directors to such persons, firms, corporations
     or associations and upon such terms as may be deemed advisable by the Board
     of Directors in the exercise of their discretion.

                                       F.

                                      SCRIP

          In no case shall fractions of shares of any class be issued by the
     Corporation, but in lieu thereof the Corporation may issue fractional Scrip
     Certificates, in either bearer or registered form, and in such
     denominations as shall be determined by the Board of Directors. Such Scrip
     Certificates shall be exchangeable on or before such date as the Board of
     Directors may fix, when surrendered with other similar Scrip Certificates
     in sufficient aggregate

                                      -24-
   11
     amounts, for certificates for full paid and non-assessable shares of the
     stock for which such Scrip Certificates are exchangeable, and the amount of
     dividends theretofore paid upon such full shares, and new Scrip
     Certificates of a like tenor for the remaining fraction of a share, if any.
     Such Scrip Certificates shall not entitle any holder thereof to voting
     rights, dividend rights or any other right of a shareholder or any rights
     other than the rights herein set forth, and no dividend or interest shall
     be payable or shall accrue with respect to the Scrip Certificates or the
     interests represented thereby. All such Scrip Certificates which are not
     surrendered in exchange for shares of stock on or before such date as the
     Board of Directors may fix, shall thereafter be void and of no effect
     whatever, except that the holders thereof shall be entitled to receive
     their pro rata share of the proceeds resulting from the sale of the full
     shares of stock for which such Scrip Certificates are exchangeable,
     together with their pro rata share of dividends theretofore paid upon such
     full shares; such sale (which may be effected either publicly or privately
     at the current market price, and as to which the Corporation may be the
     purchaser) to be made by the Corporation or by an agent of the Corporation
     (which agent may be a transfer agent or registrar of the shares for which
     such Scrip Certificates are exchangeable), as agent and on behalf of the
     holders of the Scrip Certificates.

     profits to the purchase or acquisition of property and to the purchase and
     acquisition of its own capital stock from time to time, to such extent and
     in such manner, and upon such terms as its Board of Directors shall
     determine, and neither the property nor the capital stock so purchased and
     acquired shall be regarded as profits for the purpose of declaration or
     payment of dividends, unless otherwise determined by a majority of the
     Board of Directors.

                                  ARTICLE VIII.

          A. Number, Election and Terms of Directors. The business and affairs
     of the Corporation shall be managed under the direction of its Board of
     Directors which, subject to any rights of the holders of any series of
     Preferred Stock then outstanding to elect additional directors under
     specified circumstances, shall consist of not less than twelve (12) nor
     more than twenty-five (25) persons. The exact number of directors within

     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.
     At the 1985 Annual Meeting of Shareholders, the directors shall be divided
     into three classes, as nearly equal in number as possible, 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

     at the 1988 Annual Meeting of Shareholders, and with the members of each
     class to hold office until their successors have been duly 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 and

     the holders of any series of Preferred Stock then outstanding, newly
     created directorships resulting from any increase in the authorized number
     of directors and any vacancies on the Board of Directors resulting from
     death, resignation, retirement, disqualification, removal from office or
     other cause shall be filled by a majority vote of the directors then in
     office (even though less than a quorum of the Board of Directors), and
     directors so chosen shall hold office for a term expiring at the next
     Annual Meeting of Shareholders and after their successors have been duly
     elected and qualified. If the number of directors is increased by the Board
     of Directors and the newly created directorship is filled by the Board,
     there shall be no classification of the additional directors so chosen
     until the next Annual Meeting of Shareholders at which time a majority of
     the Board shall designate the class of the director to be elected to fill
     such directorship by the shareholders. No decrease in the number of
     directors constituting the Board of Directors shall shorten the term of any
     incumbent director.

          C. Removal. Subject to the rights of the holders of any series of
     Preferred Stock then outstanding, any director or directors may be removed
     from office at any time, but only for cause and only by the affirmative
     vote of (i) 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, or (ii) a majority of the
     Board of Directors.

          D. Special Meetings of Shareholders. Special meetings of Shareholders
     of the Corporation may be called only by the Board of Directors pursuant to
     a resolution approved by a majority of the Board of Directors, upon not
     less than 30 nor more than 50 days' written notice.

     Certificate of Incorporation to the contrary, the affirmative vote of the

     Corporation entitled to vote generally in the election of directors, voting
     together as a single class, shall be required to amend or repeal, or to
     adopt any provision inconsistent with, this Article Eighth.

          subdivision of the Common Stock) except as approved by a majority of
          the total number of Disinterested Directors, and (y) an increase in

          the effect of reducing the number of outstanding shares of the Common
          Stock, unless the failure so to increase such annual rate is approved
          by a majority of the total number of Disinterested Directors; and
          (iii) such Interested Shareholder shall have not become the beneficial
          owner of any additional shares of Voting Stock except as part of the

          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).

          beneficially owned by the Interested Shareholder prior to the
          consummation of any Business Combination shall be entitled to receive

          their shares to exchange their shares in such Business Combination

     be binding and conclusive on all parties.

                Under Section 805 of the Business Corporation Law

                                ----------------


          Pursuant to the provisions of Sections 502 and 805 of the Business
Corporation Law, the undersigned hereby certify:

          1.   The name of the Corporation is McGraw-Hill, Inc. The name under
which the Corporation was formed is McGraw-Hill Publishing Company, Inc., which
name was changed to McGraw-Hill, Inc. on January 2, 1964.

          2.   The Certificate of Incorporation of the Corporation was filed by
the Department of State on the 29th of December, 1925.

          3.   The [_____________] Certificate of Incorporation of the
Corporation is hereby amended by the addition of the following provision stating
the number, designations, relative rights, preferences and limitations of a
series of Series Preferred Stock of the Corporation, designated as Series A
Preferred Stock, as fixed by the Board of Directors of the Corporation pursuant
to the authority vested in it by the Restated Certificate of Incorporation of
the Corporation:

                            SERIES A PREFERRED STOCK

          1.   Designation and Amount. The shares of such series shall be
designated as "Series A Preferred Stock" (the "Series A Preferred Stock") and
the number of shares constituting such series shall be 600,000.

          2.   Dividends and Distributions.

          (i) The holders of shares of Series A Preferred Stock, in preference
     to the holders of Common Stock and of any other junior stock, shall be
     entitled to receive, when, as and if declared by the Board of Directors out
     of funds legally available for the purpose, quarterly dividends payable in
     cash on the fifteenth day of March, June, September and December in each
     year (each such date being referred to herein as a "Quarterly Dividend
     Payment Date"), commencing on the first Quarterly Dividend Payment Date
     after the first issuance of a share or fraction of a share of Series A
     Preferred Stock, in an amount per share (rounded to the nearest cent) equal
     to the greater of (a) $25 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

                                      -33-
   20
     dividend payable in shares of Common Stock of the Corporation or a
     subdivision of the outstanding shares of Common Stock (by reclassification
     or otherwise), declared on the Common Stock since the immediately preceding
     Quarterly Divided 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 after the date hereof declare or pay any dividend on Common Stock
     payable in shares of Common Stock, or effect a subdivision or combination
     or consolidation of the outstanding shares of Common Stock (by
     reclassification or otherwise) into a greater or lesser number of shares of
     Common Stock, then in each such case the amount 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.

          (ii) The Corporation shall declare a dividend or distribution on the
     Series A Preferred Stock as provided in subparagraph (i) of this paragraph
     2 immediately after it declares a dividend or distribution on the Common
     Stock (other than a dividend payable in shares of Common Stock); provided
     that, in the event no dividend or distribution shall have been declared on
     the Common Stock during the period between any Quarterly Dividend Payment
     Date and the next subsequent Quarterly Dividend Payment Date, a dividend of
     $25 per share on the Series A Preferred Stock shall nevertheless be payable
     on such subsequent Quarterly Dividend Payment Date.

          (iii) 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 of Series A Preferred
     Stock, unless the date of issue of such shares is prior to the record date
     for the first Quarterly Dividend Payment Date, in which case dividends on
     such shares shall begin to accrue from the date of issue of such shares, or
     unless the date of issue of 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:

          (i)  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 shareholders of the
     Corporation. In the event the Corporation shall at any time after the date
     hereof declare or pay any dividend on Common Stock payable in shares of
     Common Stock, or effect a subdivision or combination or consolidation of
     the outstanding shares of Common Stock (by reclassification or otherwise)
     into a greater or lesser number of shares of Common Stock, then in each
     such case the number of votes per share to which holders of shares of
     Series A Preferred Stock were entitled immediately

                                      -34-
   21
     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.

          (ii) Except as otherwise provided herein 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 shareholders of the Corporation.

          (iii) Except as set forth herein, 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 and any other capital stock of the Corporation having general voting
     rights as set forth herein) for taking any corporate action.

          4.   Certain Restrictions.

          (i)  Whenever quarterly dividends or other dividends or distributions
payable on the Series A Preferred Stock as provided in paragraph 2 of this
Section 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:

               (a)  declare or pay dividends on, make any other distributions
          on, or redeem or purchase or otherwise acquire for consideration any
          shares of stock ranking junior (either as to dividends or upon
          liquidation, dissolution or winding up) to the Series A Preferred
          Stock;

               (b)  declare or pay dividends on or make any other distributions
          on any shares of stock ranking on a parity (either as to dividends or
          upon liquidation, dissolution of 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;

               (c)  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) with 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

               (d)  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.

          (ii) 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
     subparagraph (i) of this paragraph 4, purchase or otherwise acquire such
     shares at such time and in such manner.

                                      -35-
   22
          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 cancelled promptly after the acquisition thereof. All such
shares shall upon their cancellation become authorized but unissued shares of
Series Preferred Stock and may be reissued as part of a new series of Series
Preferred Stock to be created by resolution or resolutions of the Board of
Directors, subject to the conditions and restrictions on issuance set forth
herein.

          6.   Liquidation, Dissolution or Winding Up. Upon any liquidation,
dissolution or winding up of the Corporation, no distribution shall be made (a)
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 Common Stock, or (b) to the holders 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 other such parity stock in proportion to
the total amounts to which the holders of all such shares are entitled upon such
liquidation, dissolution or winding up. In the event the Corporation shall at
any time after the date hereof declare or pay any dividend on Common Stock
payable in shares of Common Stock, or effect a subdivision or combination or
consolidation of the outstanding shares of Common Stock (by reclassification or
otherwise) into a greater or lesser number of shares of Common Stock, then in
each such case the aggregate amount to which holders of shares of Series A
Preferred Stock were entitled immediately prior to such event under the proviso
