                                           FILED   MARCH 18, 1983 - 2:00 P.M.

                 CERTIFICATE OF INCORPORATION OF

                       UNOCAL CORPORATION

       FIRST:  The name of this corporation is:

                       UNOCAL CORPORATION

       SECOND:  The name and address of the registered agent of the
corporation in the State of Delaware is:

                  The Corporation Trust Company
                      100 West Tenth Street
             Wilmington, New Castle County, Delaware

       THIRD:  The purpose of the corporation is to engage in any
lawful act or activity for which corporations may be organized
under the General Corporation Law of Delaware.

       FOURTH:  The total amount of capital stock which this
corporation has the authority to issue is 260,000,000 shares of
common stock $1.00 par value per share.

       FIFTH:  The name and mailing address of the incorporator of
the corporation is as follows:

                    Name                   Mailing Address
               George C. Bond               P.O. Box 7600
                                   Los Angeles, California  90051

       SIXTH:  New bylaws may be adopted or the bylaws may be
amended or repealed by a vote of seventy-five percent of the
outstanding stock of the corporation entitled to vote thereon. 
Bylaws may also be adopted, amended or repealed by the Board of
Directors as provided or permitted by law; however, any bylaw
amendment adopted by the Board of Directors increasing or reducing
the authorized number of directors shall require a resolution
adopted by the affirmative vote of not less than seventy-five
percent of the directors.

       SEVENTH:  The number of directors which shall constitute the
whole Board of Directors of the corporation shall be as specified
in the bylaws of the corporation, subject to the provisions of
Article SIXTH hereof and this Article SEVENTH.  The board is
divided into three classes, Class I, Class II and Class III.  Such
classes shall be as nearly equal in number of directors as
possible.  Each director shall serve for a term ending on the third
annual meeting following the annual meeting at which such director
was elected; provided, however, that the directors first elected to
Class I shall serve for a term ending on the annual meeting next
following the end of the calendar year 1983, the directors first
elected to Class II shall serve for a term ending on the second
annual meeting next following the end of the calendar year 1983,

<PAGE>

and the directors first elected to Class III shall serve for a term
ending on the third annual meeting next following the end of the
calendar year 1983.  The foregoing notwithstanding, each director
shall serve until his successor shall have been duly elected and
qualified, unless he shall resign, become disqualified, disabled or
shall otherwise be removed.

       At each annual election, the directors chosen to succeed
those whose terms then expire shall be of the same class as the
directors they succeed, unless, by reason of any intervening
changes in the authorized number of directors, the Board shall
designate one or more directorships whose term then expires as
directorships of another class in order more nearly to achieve
equality of number of directors among the classes.

       Notwithstanding the rule that the three classes shall be as
nearly equal in number of directors as possible, in the event of
any change in the authorized number of directors each director then
continuing to serve as such shall nevertheless continue as a
director of the class of which he is a member until the expiration
of his current term, or his prior death, resignation or removal. 
If any newly created directorship may, consistent with the rule
that the three classes shall be as nearly equal in number or
directors as possible, be allocated to one or two or more classes,
the Board shall allocate it to that of the available classes whose
term of office is due to expire at the earliest date following such
allocation.
       
       EIGHTH: The affirmative vote of the holders of not less than
seventy-five percent of the outstanding stock of the corporation
entitled to vote shall be required for approval if (1) this
corporation merges or consolidates with any other corporation if
such other corporation and its affiliates singly or in the
aggregate are directly or indirectly the beneficial owners of more
than ten percent (10%) of the total voting power of all outstanding
shares of the voting stock of this corporation (such other
corporation being herein referred to as a "Related Corporation"),
or if (2) this corporation sells or exchanges all or a substantial
part of its assets to or with such Related Corporation, or if (3)
this corporation issues or delivers any stock or other securities
of its issue in exchange or payment for any properties or assets of
such Related Corporation or securities issued by such Related
Corporation, or in a merger of any affiliate of this corporation
with or into such Related Corporation or any of its affiliates;
provided, however, that the foregoing shall not apply to any such
merger, consolidation, sale or exchange, or issuance or delivery of
stock or other securities which was (i) approved by resolution of
the Board of Directors adopted by the affirmative vote of not less
than seventy-five percent of the directors prior to the acquisition
of the beneficial ownership of more then ten percent (10%) of the
total voting power of all outstanding shares of the voting stock of
the corporation by such Related Corporation and its affiliates, nor
shall it apply to any such transaction solely between this

                                2                                   
<PAGE>

corporation and another corporation fifty percent (50%) or more of
the voting stock of which is owned by this corporation. For the
purposes hereof, an "affiliate" is any person (including a
corporation, partnership, trust, estate or individual) who
directly, or indirectly through one or more intermediaries,
controls, or is controlled by, or is under common control with, the
person specified. "Control" means the possession, directly or
indirectly, of the power to direct or cause the direction of the
management and policies of a person, whether through the ownership
of voting securities, by contract, or otherwise; and in computing
the percentage of outstanding voting stock beneficially owned by
any person the shares outstanding and the shares owned shall be
determined as of the record date fixed to determine the
stockholders entitled to vote or express consent with respect to
such proposal. The stockholder vote, if any, required for mergers,
consolidations, sales or exchanges of assets or issuances of stock
or other securities not expressly provided for in this Article,
shall be such as may be required by applicable law. A "substantial
part" of the corporation's assets shall mean assets comprising more
than ten percent of the book value of fair market value of the
total assets of the corporation and its subsidiaries taken as a
whole.

       NINTH: No action shall be taken by the stockholders except
at an annual or special meeting of stockholders. No action shall be
taken by stockholders by written consent.

       TENTH: Special meetings of the stockholders of the
corporation for any purpose or purposes may be called at any time
by the Board of Directors, or by a majority of the members of the
Board of Directors, or by a committee of the Board of Directors
which has been duly designated by the Board of Directors and whose
powers and authority, as provided in a resolution of the Board of
Directors or in the by-laws of the corporation, include the power
to call such meetings, but such special meetings may not be called
by any other person or persons; provided, however, that, if and to
the extent that any special meeting of stockholders may be called
by any other person or persons specified in any provisions of this
Certificate of Incorporation or any amendment thereto, then such
special meeting may also be called by the person or persons, in the
manner, at the times and for the purposes so specified.

       ELEVENTH: The corporation reserves the right to amend,
alter, change or repeal any provision contained in this Certificate
of Incorporation, in the manner now or hereafter prescribed by
statute, and all rights conferred on stockholders herein are
granted subject to this reservation. Notwithstanding the foregoing,
the provisions set forth in Articles SIXTH, SEVENTH, EIGHTH, NINTH,
TENTH and this Article ELEVENTH may not be repealed or amended in
any respect unless such repeal or amendment is approved by the
affirmative vote of the holders of not less than seventy-five
percent of the total voting power of all outstanding shares of
voting stock of this corporation.

million (350,000,000) shares, consisting of two hundred fifty
million (250,000,000) shares of Common Stock, having a par value of

Stock, without a vote of the holders of the Preferred Stock, or of
any series thereof, unless a vote of any such holders, is required

          SERIES A JUNIOR PARTICIPATING CUMULATIVE PREFERRED STOCK

                               Of

                       UNOCAL CORPORATION

     Pursuant to Section 151 of the General Corporation Law 
                    of the State of Delaware


          We, Sam A. Snyder, Vice President, and R. E. Jenkins,
Assistant Secretary, Of Unocal Corporation, a corporation organized
and existing under the General Corporation of the State of
Delaware, in accordance with the provisions Law Section 103
thereof, DO HEREBY CERTIFY:

          That Pursuant to the authority conferred upon the Board
of Directors by the Certificate of Incorporation of the
Corporation, the Board of Directors on January 29, 1990 adopted the
following resolution creating a series of 2,500,000 shares of
Preferred Stock, par value $.10 per share, designated as Series A
Junior Participating Cumulative Preferred Stock:

          RESOLVED, that pursuant to the authority vested in the
Board of Directors of this Corporation in accordance with the
provisions of its Certificate of Incorporation, a series of
Preferred Stock of the Corporation be, and it hereby is, created,
and that the designation and amount thereof and the voting powers,
preferences and relative, participating, optional and other special
rights of the shares of such series, and the qualifications,
limitations or restrictions thereof, are as follows:

          Section 1.  Designation and Amount.  The shares of such
series shall be designated as Series A Junior Participating
Cumulative Preferred Stock, par value $.10 per share (the "Series
A Preferred Stock"), and the number of shares constituting such
series shall be 2,500,000.

          Section 2.  Dividends and Distributions.

          (a)  The holders of shares of Series A Preferred
Stock, in preference to the holders of shares of Common Stock,
$1.00 per share, of the Corporation (the "Common Stock") and of any
other junior stock of the Corporation that may be outstanding,
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 tenth day of January,
April, July and October 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 (i) $0.25 per share ($1.00 per annum), or (ii) subject

<PAGE>

to the provision for adjustment hereinafter set forth, 100 times
the aggregate per share amount of all cash dividends, and 100 times
the aggregate per share amount (payable in kind) of all non-cash
dividends or other distributions, other than a dividend payable in
shares of Common Stock, or a subdivision of the outstanding shares
of Common Stock (by reclassification or otherwise), declared on the
Common Stock since the immediately preceding Quarterly Dividend
Payment Date or, with respect to the first Quarterly Dividend
Payment Date, since the first issuance of any share or fraction of
a share of Series A Preferred Stock.  In the event that the
Corporation shall at any time 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 and in each such event, the
amount to which holders of shares of Series A Preferred Stock were
entitled immediately prior to such event under clause (ii) of the
preceding sentence shall be adjusted by multiplying such amount by
a fraction, the numerator of which is the number of shares of
Common Stock outstanding immediately after such event, and the
denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

          (b) The Corporation shall declare a dividend or
distribution on the Series A Preferred Stock as provided in
paragraph (a) of this Section 2 immediately after it declares a
dividend or distribution on the Common Stock (other than a dividend
payable in shares of Common Stock); provided, however, 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 $0.25 per share ($1.00 per annum) on the Series
A Preferred Stock shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

          (c) Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Preferred Stock from the Quarterly
Dividend Payment Date next preceding the date of issue of such
shares 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 is a Quarterly Dividend Payment Date or is a date
after the record date for the determination of holders of shares of
Series A Preferred Stock entitled to receive a quarterly dividend
and before such Quarterly Dividend Payment Date, in either of which
cases such dividends shall begin to accrue and be cumulative from
such Quarterly Dividend Payment Date.  Accrued but unpaid dividends
shall cumulate but 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

                               -2-

<PAGE>

may fix a record date for the determination of holders of shares of
Series A Preferred Stock entitled to receive payment of a dividend
or distribution declared thereon, which record date shall be not
more than 60 days prior to the date fixed for the payment thereof.

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

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

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

          (c)  In addition, the holders of shares of Series A
Preferred Stock shall have the following special voting rights:

          In the event that at any time dividends on Series A
          Preferred Stock, whenever accrued and whether or not
          consecutive, shall not have been paid or declared and a
          sum sufficient for the payment thereof set aside, in an
          amount equivalent to six quarterly dividends on all
          shares of Series A Preferred Stock at the time
          outstanding, then and in each such event, the holders of
          shares of Series A Preferred Stock and each other series
          of preferred stock now or hereafter issued that shall be
          accorded such class voting right by the Board of
          Directors and that shall have the right to elect three
          directors as the result of a prior or subsequent default
          in payment or dividends on such series (each such other
          series being hereinafter called "Other Series of
          Preferred Stock"), voting separately as a class without
          regard to series, shall be entitled to elect three
          directors at the next annual meeting of stockholders of
          the Corporation, in addition to the directors to be

                               -3-
<PAGE>

          elected by the holders of all shares of the Corporation
          entitled to vote for the election of directors, and the
          holders of all shares (including the Series A Preferred
          Stock) otherwise entitled to vote for directors, voting
          separately as a class, shall be entitled to elect the
          remaining members of the Board of Directors, provided
          that the Series A Preferred Stock and each Other Series
          of Preferred Stock, voting as a class, shall not have the
          right to elect more than three directors.  Such special
          voting right of the holders of shares of Series A
          Preferred Stock may be exercised until all dividends in
          default on the Series A Preferred Stock shall have been
          paid in full or declared and funds sufficient therefor
          set aside, and when so paid or provided for, such special
          voting right of the holders of shares of Series A
          Preferred Stock shall cease, but subject always to the
          same provisions for the vesting of such special voting
          rights in the event of any such future dividend default
          or defaults.  At any time after such special voting
          rights shall have so vested in the holders of shares of
          Series A Preferred Stock, the Secretary of the
          Corporation may, and upon the written request of the
          holders of record of 10% or more in number of the shares
          of Series A Preferred Stock and each Other Series of
          Preferred Stock then outstanding addressed to the
          Secretary at the principal executive office of the
          Corporation shall, call a special meeting of the holders
          of shares of Preferred Stock so entitled to vote, for the
          election of the directors to be elected by them as herein
          provided, to be held within 60 days after such call and
          at the place and upon the notice provided by law and in
          the Bylaws for the holding of meetings of stockholders;
          provided, however, that the Secretary shall not be
          required to call such special meeting in the case of any
          such request received less than 90 days before the date
          fixed for any annual meeting of stockholders, and if in 
          such case such special meeting is not called or held, the
          holders of shares of Preferred Stock so entitled to vote
          shall be entitled to exercise the special voting rights
          provided in this paragraph at such annual meeting.  If
          any such special meeting required to be called as above
          provided shall not be called by the Secretary within 30
          days after receipt of any such request, then the holders
          of record of 10% or more in number of the shares of
          Series A Preferred Stock and each Other Series of
          Preferred Stock then outstanding may designate in writing
          one of their number to call such meeting, and the person
          so designated may, at the expense of the Corporation,
          call such meeting to be held at the place and upon the
          notice given by such person, and for that purpose shall
          have access to the stock books of the Corporation.  No
          such special meeting and no adjournment thereof shall be
          held on a date later than 60 days before the annual

                               -4-
<PAGE>          

          meeting of stockholders.  If, at any meeting so called or
          at any annual meeting held while the holders of shares of
          Series A Preferred Stock have the special voting rights
          provided for in this paragraph, the holders of not less
          than 40% of the shares of Series A Preferred Stock and
          each Other Series of Preferred Stock then outstanding are
          present in person or by proxy, which percentage shall be
          sufficient to constitute a quorum for the election of
          additional directors as herein provided, the then
          authorized number of directors of the Corporation shall
          be increased by three, as of the time of such special
          meeting or the time of the first such annual meeting held
          while such holders have special voting rights and such
          quorum is present, and the holders of shares of Series A
          Preferred Stock and each Other Series of Preferred Stock,
          voting as a class, shall be entitled to elect the
          additional directors so provided for.  If the directors
          of the Corporation are then divided into classes under
          provisions of the Certificate of Incorporation of the
          Corporation or the Bylaws, the three additional directors
          shall be members of those respective classes of directors
          in which a vacancy is created as a result of such
          increase in the authorized number of directors.  If the
          foregoing expansion of the size of the Board of Directors

          A Preferred Stock, except dividends paid ratably on
          shares of the series A Preferred Stock and all such
          parity stock on which dividends are payable or in arrears

          Section 6.  Liquidation, Dissolution or Winding Up.
Upon any liquidation, dissolution or winding up of the Corporation,

          (a)  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
the greater of (i) $1.00 per share ($.01 per one one-hundredth of
a share), plus an amount equal to accrued and unpaid dividends and
distributions thereon, whether or not declared, to the date of such
payment, or (ii) an aggregate amount per share, subject to the
provision for adjustment hereinafter set forth, equal to 100 times
the aggregate amount to be distributed per share to holders of
shares of Common Stock; or

          (b)  the holders of shares of stock ranking on a parity
(either as to dividends or upon liquidation, dissolution or winding
up) with the Series A Preferred Stock, except distributions made
ratably on the Series A Preferred Stock and all 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 that the Corporation shall at any time
declare or pay any dividend on Common Stack 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 and in each such event, the aggregate
amount to which holders of shares of Series A Preferred Stock were
entitled immediately prior to such event under the proviso in
clause (a) 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.

          Section 7.  Consolidation, Merger, etc.  In the event

combination or other transaction in which the shares of Common

the same time be similarly exchanged or changed in an amount per
share (subject to the provision for adjustment hereinafter set
forth) equal to 100 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as
the case may be, into which or for which each share of Common Stock
is changed or exchanged. In the event that the Corporation shall at
any time 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 and in each such event, the amount set

                               -9-
<PAGE>


forth in the preceding sentence with respect to the exchange or
change of shares of Series A Preferred Stock shall be adjusted by
multiplying such amount by a fraction, the numerator of which is
the number of shares of Common stock outstanding immediately after
such event, and the denominator of which is the number of shares of
Common Stock that were outstanding immediately prior to such event.

          Section 8.  No Redemption.  The shares of Series A
Preferred Stock shall not be redeemable.  Notwithstanding the
foregoing, the Corporation may acquire shares of Series A Preferred
Stock in any other manner permitted by law, the Certificate of
Incorporation of the Corporation or herein.

          Section 9.  Rank.  Unless otherwise provided in the
Certificate of Incorporation of the Corporation or a Certificate of
Designations relating to a subsequent series of preferred stock of
the Corporation, the Series A Preferred Stock shall rank junior to
all other series of the Corporation's preferred stock as to the
payment of dividends and the distribution of assets on liquidation,
dissolution or winding up, and senior to the Common Stock of the
Corporation.

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

          Section 11.  Fractional Shares.  Series A Preferred Stock
maybe issued in fractions of a share (in one one-hundredths (1/100)
of a share and integral multiples thereof) that shall entitle the
bolder thereof, in proportion to such holder's fractional shares,
to exercise voting rights, receive dividends, participate in
distributions and have the benefit of all other rights of holders
of shares of Series A Preferred Stock.

          IN WITNESS WHEREOF, we have executed and subscribed this
Certificate and do affirm the foregoing as true under the penalties
of perjury this 31st day of January, 1990.

     FOURTH: The total number of shares of stock which the
corporation shall have authority to issue is eight hundred fifty
million (850,000,000) shares, consisting of seven hundred fifty
million (750,000,000) shares of Common Stock, having a par value of
$1.00 per share, and one hundred million (100,000,000) shares of
Preferred Stock, having a par value of $0.10 per share.

     The board of directors is authorized, subject to any
limitations prescribed by law, to provide for the issuance of the
shares of Preferred Stock in one or more series, and by filing a

Delaware, to establish from time to time the number of shares to be
included in each such series, and to fix the distribution, powers,
preferences, and rights of the shares of each such series and any
qualifications, limitations or restrictions thereof. The number of
authorized shares of Preferred Stock may be increased or decreased
(but not below the number of shares thereof then outstanding) by
the affirmative vote of the holders of a majority of the Common
Stock, without a vote of the holders of the Preferred Stock, or of
any series thereof, unless a vote of any such holders is required
pursuant to the certificate or certificates establishing the series
of Preferred Stock.

     3.  The foregoing amendment has been approved by the Board of
Directors and by a vote of the Stockholders pursuant to Section 242
of the Delaware General Corporation Law at the Annual Meeting of
Stockholders held on April 30, 1990.

                   CERTIFICATE OF DESIGNATIONS
                             OF THE
                $3.50 CONVERTIBLE PREFERRED STOCK
                   (Par Value $0.10 Per Share)

                               OF
                       UNOCAL CORPORATION
                                        

                 Pursuant to Section 151 of the
        General Corporation Law of the State of Delaware
                                        


          The undersigned DOES HEREBY CERTIFY that the following
resolution was duly adopted by the Executive Committee of the Board
of Directors (the "Board of Directors") of Unocal Corporation, a
Delaware corporation (hereinafter called the "Corporation"), at
meetings duly convened and held at which a quorum was present and
acting throughout, and pursuant to authority duly delegated by the
Board of Directors:

          RESOLVED that pursuant to the authority expressly granted
to and vested in the Board of Directors by the Certificate of
Incorporation of the Corporation (the "Certificate of
Incorporation"), and pursuant to the authority conferred on this
Executive Committee by resolutions duly adopted by the Board of
Directors, the Executive Committee authorizes the creation of a
series of $3.50 Convertible Preferred Stock, par value $0.10 per
share, of the Corporation upon the terms and conditions set forth
herein and hereby fixes the designation and number of shares
thereof and ratifies the voting powers (as previously established
by resolution of the Board of Directors, as set forth in Section 7
below) and fixes the other powers, preferences and relative,
participating, optional or other special rights, and the
qualifications, limitations and restrictions thereof (in addition
to those set forth in the Certificate of Incorporation which may be
applicable to the $3.50 Convertible Preferred Stock) as follows:

               1.     Designation and Amount; Fractional Shares. 
          There shall be a series of Preferred Stock of the
          Corporation designated as "$3.50 Convertible Preferred
          Stock" and the number of shares constituting such series
          shall be 11,000,000.  Such series is referred to herein
          as the "Convertible Preferred Stock."  The Convertible
          Preferred Stock is issuable solely in whole shares which
          shall entitle the holder to exercise voting rights, to
          participate in distributions and to have the benefit of
          all other rights of holders of Convertible Preferred
          Stock.

               2.     Par Value.  The par value of each share of
          Convertible Preferred Stock shall be $0.10.

               3.     Dividends.  
               
                     (a) The holders of Convertible Preferred Stock shall be 
          entitled to receive, when, as and if declared by the Board of 
          Directors or, to the extent permitted by applicable law, a 
      
<PAGE>          
          
          
          duly authorized committee thereof, out of funds at the time 
          legally available therefor, cash dividends at an annual rate 
          of $3.50 per share, and no more, which shall be fully
          cumulative, shall accrue without interest from the date shares 
          of Convertible Preferred Stock are first issued (the "Date of 
          Original Issue") and shall be payable in cash quarterly in 
          arrears on January 15, April 15, July 15 and October 15 of 
          each year commencing October 15, 1992 (each, a "Dividend 
          Payment Date") (except that if any such date is a Saturday, 
          Sunday or legal holiday, then such dividend shall be payable 
          on the next day that is not a Saturday, Sunday or legal 
          holiday) to holders of record as they appear upon the stock 
          transfer books of the Corporation on such record dates, not 
          more than sixty days nor less than ten days preceding the 
          payment dates for such dividends, as are fixed by the Board of
          Directors or, to the extent permitted by applicable law, a 
          duly authorized committee thereof (each, a "Record Date").  
          For purposes hereof, the term "legal holiday" shall mean any 
          day on which banking institutions are authorized to close in 
          New York, New York or in Los Angeles, California.  Subject to 
          paragraph (c) of this Section 3, dividends on account of 
          arrearages for any past Dividend Period (as defined below) may 
          be declared and paid at any time, without reference to any 
          regular Dividend Payment Date.

               Holders of shares of Convertible Preferred Stock
          called for redemption on a redemption date between a
          Record Date and the corresponding Dividend Payment Date
          shall not be entitled to receive the dividend payable on
          such Dividend Payment Date.  As used herein, (i) the term
          "Initial Dividend Period" shall mean the period from and
          including the Date of Original Issue to and excluding
          October 15, 1992, (ii) the term "Subsequent Dividend
          Period" shall mean the applicable period from January 15
          to and excluding the next April 15, from April 15 to and
          excluding the next July 15, from July 15 to and excluding
          the next October 15 or from October 15 to and excluding
          the next January 15, or, in each such case as to
          particular shares of the Convertible Preferred Stock,
          such shorter period during which such shares of the
          Convertible Preferred Stock are outstanding (excluding
          the last day of such shorter period), but shall not
          include the Initial Dividend Period and (iii) the term
          "Dividend Period" shall mean the Initial Dividend Period
          or any Subsequent Dividend Period, as the context
          requires.

               (b)    The amount of dividends payable on each share
          of the Convertible Preferred Stock for each full
          quarterly Dividend Period during which such share was
          outstanding shall be $0.875. For the Initial Dividend
          Period and any Subsequent Dividend Period during which
          such share was not outstanding for a full quarterly
          Dividend Period, the amount of dividends payable on each
          such share of the Convertible Preferred Stock shall be
          computed on the basis of a 360-day year consisting of
          
          
                               -2-
<PAGE>          
          
          twelve 30-day months.  Unless otherwise provided herein,
          dividends on each share of the Convertible Preferred
          Stock will be  cumulative from the Date of Original Issue
          to and excluding the earlier to occur of (A) the date of
          redemption of such share of the Convertible Preferred
          Stock and (B) the date of final distribution of assets
          upon any voluntary or involuntary liquidation,
          dissolution or winding up of the Corporation.  Holders of
          shares of the Convertible Preferred Stock shall not be
          entitled to any interest, or sum of money in lieu of
          interest, in respect of any dividend payment or payments
          on shares of the Convertible Preferred Stock which may be
          in arrears.  Any dividend payment made on shares of the
          Convertible Preferred Stock shall first be credited
          against the earliest accumulated but unpaid dividend with
          respect to shares of the Convertible Preferred Stock.

               (c)    No full dividends shall be declared or paid
          or set apart for payment for any period on any class or
          series of the Corporation's capital stock hereafter
          issued ranking junior to or on a parity with the
          Convertible Preferred Stock (including the Corporation's
          Series A Junior Participating Cumulative Preferred Stock)
          as to dividends unless full cumulative dividends have
          been or contemporaneously are declared and paid or
          declared and a sum sufficient for the payment thereof is
          set apart for such payment on the Convertible Preferred
          Stock for all dividend payment periods terminating on or
          prior to the date of the payment of such full cumulative
          dividends.  When dividends are not paid in full on the
          Convertible Preferred Stock and on any other series of
          the Corporation's preferred stock ranking on a parity as
          to dividends with the Convertible Preferred Stock, all
          dividends declared upon all outstanding shares of the
          Convertible Preferred Stock and shares of such other
          series of preferred stock will be declared pro rata so
          that the amounts of dividends declared per share on the
          Convertible Preferred Stock and such other preferred
          stock will in all cases bear to each other the same ratio
          that accumulated and unpaid dividends per share on the
          shares of the Convertible Preferred Stock and such other
          preferred stock bear to each other.

               (d)    No dividend (other than a dividend in Common
          Stock or in any other stock of the Corporation ranking
          junior to the Convertible Preferred Stock as to dividends
          and upon liquidation and other than as provided in
          paragraph (c) of this Section 3) may be declared or paid
          or set apart for payment or other distribution declared
          or made upon the Common Stock or upon any other stock of
          the Corporation ranking junior to or on a parity with the
          Convertible Preferred Stock as to dividends or upon
          liquidation, nor may any Common Stock or any other stock
          of the Corporation ranking junior to or on a parity with
          the Convertible Preferred Stock as to dividends or upon
          liquidation be redeemed, purchased or otherwise acquired
          for any consideration (or any moneys be paid to or 
          
                               -3-
<PAGE>

          made available for a sinking fund for the redemption of any
          shares of such stock) by the Corporation (except by
          conversion into or in exchange for stock of the
          Corporation ranking junior to the Convertible Preferred
          Stock as to dividends and upon liquidation) unless full
          cumulative dividends on all outstanding shares of the
          Convertible Preferred Stock have been paid or declared
          and set apart for payment for all dividend payment
          periods ending on or prior to the date of declaration,
          payment, redemption, purchase or acquisition of the
          Common Stock or such other preferred stock referred to
          above in this paragraph (d); provided, however, that
          notwithstanding the above, the Corporation shall have the
          right to redeem the Preferred Stock Purchase Rights, as
          defined in Section 6(k), and nothing herein shall prevent
          the Corporation from making contributions to its employee
          benefit plans.

               (e)    Any reference to "distribution" contained in
          this Section 3 shall not be deemed to include any
          distribution made in connection with any liquidation,
          dissolution or winding up of the Corporation, whether
          voluntary or involuntary.

               4.     Liquidation Preference.  In the event of a
          liquidation, dissolution or winding up of the
          Corporation, whether voluntary or involuntary, each
          holder of a share of Convertible Preferred Stock shall be
          entitled to receive, and be paid out of the assets of the
          Corporation available for distribution to its
          stockholders, a liquidation preference in the amount of
          $50.00 per share, plus all accumulated and unpaid
          dividends on such share on the date of final distribution
          to the holders of shares of Convertible Preferred Stock,
          whether or not declared, without interest, and no more,
          before any payment shall be made or any assets
          distributed to the holders of Common Stock or any other
          class of the Corporation's stock ranking junior to the
          Convertible Preferred Stock upon liquidation (including
          the Corporation's Series A Junior Participating
          Cumulative Preferred Stock).  If, upon any liquidation,
          dissolution or winding up of the Corporation, the amounts
          payable with respect to the liquidation preference of the
          Convertible Preferred Stock and any other shares of the
          Corporation's stock ranking on a parity with the
          Convertible Preferred Stock are not paid in full, the
          holders of Convertible Preferred Stock and of such other
          shares will share ratably in any such distribution of
          assets of the Corporation in proportion to the full
          distributable amounts to which they are entitled as
          measured by the liquidation preferences of the
          Convertible Preferred Stock and such other stock.  After
          payment in full of the preferences of the shares of the
          Convertible Preferred Stock upon liquidation, dissolution
          or winding up, the holders of such shares in their
          capacity as such shall not be entitled to any further
          participation in any distribution of assets by the
          Corporation.  Neither a consolidation or merger of the
          Corporation with or into another corporation nor a merger
          of any other corporation with or into the Corporation,
          nor the sale of all or substantially all of the
          
                               -4-
<PAGE>          
          
          Corporation's property or business (other than in
          connection with a winding up of its business) will be
          considered a liquidation, dissolution or winding up of
          the Corporation.

               5.     Redemption at Option of the Corporation.  (a)
          The Convertible Preferred Stock may not be redeemed by
          the Corporation prior to July 15, 1996.  On or after July
          15, 1996, the Convertible Preferred Stock may be redeemed
          by the Corporation, at its option on any date set by the
          Board of Directors (or, to the extent permitted by
          applicable law, a duly authorized committee thereof), in
          whole or in part, out of funds legally available
          therefor, at any time or from time to time, at the
          following redemption prices per share (expressed as a
          percentage of the $50.00 liquidation preference thereof),
          if redeemed during the 12-month period beginning July 15
          of the year indicated:

                          Year               Redemption Price
                          ----               ----------------
                          1996                   104.2%
                          1997                   103.5%
                          1998                   102.8%
                          1999                   102.1%
                          2000                   101.4%
                          2001                   100.7%

          and thereafter at $50.00 per share, plus, in each case,
          an amount in cash equal to all accumulated and unpaid
          dividends thereon, whether or not declared, to but
          excluding the date fixed for redemption, such sum being
          hereinafter referred to as the "Redemption Price."

               (b)    In case of the redemption of less than all of
          the then outstanding shares of Convertible Preferred
          Stock, the Corporation shall designate by lot, or in such
          other manner as the Board of Directors (or, to the extent
          permitted by applicable law, a duly authorized committee
          thereof) may determine to be equitable, the shares to be
          redeemed, or shall effect such redemption pro rata. 
          Notwithstanding the foregoing, the Corporation shall not
          redeem less than all of the Convertible Preferred Stock
          at any time outstanding until all dividends accumulated
          and in arrears upon all shares of Convertible Preferred
          Stock shall have been paid for all Dividend Periods
          terminating on or prior to the redemption date.

               (c)    Not more than sixty nor less than thirty days prior 
          to the redemption date fixed by the Board of Directors, notice 
          by first class mail, postage prepaid, shall be given to the 
          holders of record of shares of the Convertible Preferred Stock 
          to be redeemed, addressed to such holders at their last 
          addresses as shown upon the stock transfer books of the 
          
                               -5-
<PAGE>          

          
          Corporation.  Each such notice of redemption shall specify (i) 
          the date fixed for redemption, (ii) the number of shares of 
          Convertible Preferred Stock to be redeemed, and if less than all the
          shares held by such holder are to be redeemed, the number
          of such shares to be redeemed from such holder, (iii) the
          Redemption Price, (iv) the place or places of payment,
          (v) that payment will be made upon presentation and
          surrender of the certificates representing shares of
          Convertible Preferred Stock, (vi) that on and after the
          redemption date dividends will cease to accumulate on
          such shares, (vii) the then-effective conversion price
          (as defined in Section 6) and (viii) that the right of
          holders to convert shares of Convertible Preferred Stock
          shall terminate at the close of business on the date
          fixed for redemption (unless the Corporation defaults in
          the payment of the Redemption Price).

               (d)    Any notice that is mailed as herein provided
          shall be conclusively presumed to have been duly given,
          whether or not the holder of shares of Convertible
          Preferred Stock receives such notice; and failure to give
          such notice by mail, or any defect in such notice to the
          holders of any shares designated for redemption shall not
          affect the validity of the proceedings for the redemption
          of any other shares of Convertible Preferred Stock.  On
          or after the date fixed for redemption as stated in such
          notice, each holder of the shares called for redemption
          shall surrender the certificate evidencing such shares to
          the Corporation at the place designated in such notice
          and shall thereupon be entitled to receive payment of the
          Redemption Price for each such share.  If less than all
          the shares evidenced by any such surrendered certificate
          are redeemed, a new certificate shall be issued
          evidencing the unredeemed shares.  Notice having been
          given as aforesaid, if, on the date fixed for redemption,
          funds necessary for the redemption shall be available
          therefor and shall have been irrevocably deposited or set
          aside, then, notwithstanding that the certificates
          evidencing any shares so called for redemption shall not
          have been surrendered, (i) dividends with respect to the
          shares so called shall cease to accrue on the date fixed
          for redemption, (ii) such shares shall no longer be
          deemed outstanding, (iii) the holders thereof shall cease
          to be stockholders of the Corporation and (iv) all rights
          whatsoever with respect to the shares so called for
          redemption (except the right of the holders to receive
          the Redemption Price for each share without interest upon
          surrender of their certificates therefor) shall
          terminate.  If funds legally available for such purpose
          are not sufficient for redemption of the shares of
          Convertible Preferred Stock which were to be redeemed,
          then the certificates evidencing such shares shall be
          deemed not to be surrendered, such shares shall remain
          outstanding and the right of holders of shares of
          Convertible Preferred Stock thereafter shall continue to
          be only those of a holder of shares of the Convertible
          Preferred Stock.

                               -6-

               (e)    The shares of Convertible Preferred Stock shall not 
          be subject to the operation of any mandatory redemption, 
          purchase, retirement or sinking fund.

               6.     Conversion Privileges.

               (a)  Rights of Conversion.  Each holder of shares of
          Convertible Preferred Stock shall have the right, at such
          holder's option, to convert all or a portion of the
          shares held, at any time after September 6, 1992, and
          prior to the close of business on the date fixed for
          redemption of such shares as herein provided, into fully
          paid and nonassessable shares of Common Stock (calculated
          as to each conversion to the nearest 1/100th of a share)
          and such other securities and property as hereinafter
          provided, at the rate of that number of shares of Common
          Stock for each full share of Convertible Preferred Stock
          that is equal to $50.00 divided by the conversion price
          applicable per share of Common Stock.  For purposes of
          this resolution, the "conversion price" applicable per
          share of Common Stock shall initially be equal to $30.75,
          and shall be adjusted from time to time in accordance
          with the provisions of this Section 6.  Any share of
          Convertible Preferred Stock may be converted, at the
          request of its holder, in part into Common Stock.  

               For the purpose of this Section 6, the term "Common
          Stock" shall mean the class designated as Common Stock,
          par value $1.00 per share, of the Corporation as of July
          21, 1992, or such class as it shall be constituted from
          time to time.

               (b)    Conversion Procedures.  Any holder of shares
          of Convertible Preferred Stock desiring to convert such
          shares into Common Stock shall surrender the certificate
          or certificates evidencing such shares of Convertible
          Preferred Stock at the office of the transfer agent for
          the Convertible Preferred Stock, which certificate or
          certificates, if the Corporation shall so require, shall
          be duly endorsed to the Corporation or in blank, or
          accompanied by proper instruments of transfer to the
          Corporation or in blank, accompanied by (i) an
          irrevocable written notice to the Corporation that the
          holder elects to convert such shares of Convertible
          Preferred Stock and specifying the name or names (with
          address or addresses) in which a certificate or
          certificates evidencing shares of Common Stock are to be
          issued and (ii) if required pursuant to Section 6(f), an
          amount sufficient to pay any transfer or similar tax (or
          evidence reasonably satisfactory to the Corporation
          demonstrating that such taxes have been paid).

               Holders of shares of Convertible Preferred Stock at
          the close of business on a Record Date shall be entitled
          to receive the dividend payable on those shares (except as 
          provided in the penultimate sentence of Section 3(a)) on the 
          
                               -7-
<PAGE>

          corresponding Dividend Payment Date notwithstanding the 
          conversion thereof following such Record Date and prior to the 
          Dividend Payment Date.  However, shares of Convertible Preferred 
          Stock surrendered for conversion during the period between the
          close of business on any Record Date and the opening of
          business on the corresponding Dividend Payment Date
          (except as provided in the penultimate sentence of
          Section 3(a)) must be accompanied by payment of an amount
          equal to the dividend payable on such shares on such
          Dividend Payment Date.  A holder of shares of Convertible
          Preferred Stock on a Record Date who tenders any such
          shares for conversion into shares of Common Stock on or
          after such Dividend Payment Date will receive the
          dividend payable by the Corporation on such shares of
          Convertible Preferred Stock on such Dividend Payment
          Date, and the converting holder need not include payment
          of the amount of such dividend upon surrender of shares
          of Convertible Preferred Stock for conversion.  Except as
          provided for above, no payments or adjustments in respect
          of dividends on shares of Convertible Preferred Stock
          surrendered for conversion (whether or not in arrears) or
          on account of any dividend on the Common Stock issued
          upon conversion shall be made upon the conversion of any
          shares of Convertible Preferred Stock.

               The Corporation shall, as soon as practicable after
          such deposit of certificates evidencing shares of
          Convertible Preferred Stock accompanied by the written
          notice and compliance with any other conditions herein
          contained, deliver at such offices of such transfer agent
          to the person for whom such shares of Convertible
          Preferred Stock are so surrendered, or to the nominee or
          nominees of such person, certificates evidencing the
          number of full shares of Common Stock to which such
          person shall be entitled as aforesaid, together with a
          cash adjustment in respect of any fraction of a share of
          Common Stock as hereinafter provided.  Subject to the
          following provisions of this paragraph, each conversion
          shall be deemed to have been effected immediately prior
          to the close of business on the date on which the
          certificates for shares of Convertible Preferred Stock to
          be converted shall have been surrendered together with
          the irrevocable written notice and payment of taxes (if
          applicable) as provided for in clauses (i) and (ii) above
          and an amount equal to the dividend payable (if
          appropriate) as provided in the second paragraph of this
          Section 6(b), and the person or persons entitled to
          receive the Common Stock deliverable upon conversion of
          such Convertible Preferred Stock shall be treated for all
          purposes as the record holder or holders of such Common Stock at 
          such time on such date, unless the stock transfer books of the 
          Corporation shall be closed on such date, in which event such 
          person or persons shall be deemed to have become such holder 
          or holders of record at the close of business on the next 
          succeeding day on which such stock transfer books are open, 
          but such conversion shall be at the conversion price in effect 
          
          
                               -8-

          on the date on which such shares shall have been surrendered 
          and such notice (and, if applicable, payments) received by the
          Corporation.

               (c)    Adjustment of Conversion Price.  The
          conversion price at which a share of Convertible
          Preferred Stock is convertible into Common Stock shall be
          subject to adjustment from time to time as follows:

                      (i)  In case the Corporation shall pay or
               make a dividend or other distribution on its Common
               Stock exclusively in Common Stock or shall pay or
               make a dividend or other distribution on any other
               class of capital stock of the Corporation which
               dividend or distribution includes Common Stock, the
               conversion price in effect at the opening of
               business on the day following the date fixed for
               the determination of stockholders entitled to
               receive such dividend or other distribution shall
               be reduced by multiplying such conversion price by
               a fraction of which the numerator shall be the
               number of shares of Common Stock outstanding at the
               close of business on the date fixed for such
               determination and the denominator shall be the sum
               of such number of shares and the total number of
               shares constituting such dividend or other
               distribution, such reduction to become effective
               immediately after the opening of business on the
               day following the date fixed for such
               determination.  In the event that such dividend or
               distribution is not so paid or made, the conversion
               price shall again be adjusted to be the conversion
               price which would then be in effect if such date
               fixed for the determination of stockholders
               entitled to receive such dividend or other
               distribution had not been fixed.

                      (ii)  In case the Corporation shall pay or
               make a dividend or other distribution on its Common
               Stock consisting exclusively of rights or warrants
               entitling the holders thereof to subscribe for or
               purchase, during a period not exceeding 45 days
               from the date of such dividend or other
               distribution, shares of Common Stock at a price per
               share less than the current market price per share
               (determined as provided in subparagraph (v) of this
               Section 6(c)) of the Common Stock on the date fixed
               for the determination of stockholders entitled to
               receive such rights or warrants, the conversion
               price in effect at the opening of business on the
               day following the date fixed for such determination
               shall be reduced by multiplying such conversion
               price by a fraction of which the numerator shall be
               the number of shares of Common Stock outstanding at
               the close of business on the date fixed for such
               determination plus the number of shares of Common
               Stock which the aggregate of the offering price of
               the total number of shares of Common Stock so offered for 
               
                               -9-
<PAGE>          
          
               subscription or purchase would purchase at such current 
               market price and the denominator shall be the number of 
               shares of Common Stock outstanding at the close of business 
               on the date fixed for such determination plus the number of
               shares of Common Stock so offered for subscription
               or purchase, such reduction to become effective
               immediately after the opening of business on the
               day following the date fixed for such
               determination.  To the extent that shares of Common
               Stock are not delivered after the expiration of
               such rights or warrants, the conversion price shall
               be readjusted to the conversion price which would
               then be in effect had the adjustments made upon the
               issuance of such rights or warrants been made on
               the basis of delivery of only the number of shares
               of Common Stock actually delivered.  In the event
               that such rights or warrants are not so issued, the
               conversion price shall again be adjusted to be the
               conversion price which would then be in effect if
               such date fixed for the determination of
               stockholders entitled to receive such rights or
               warrants had not been fixed.  

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

                      (iv)  Subject to the last sentence of this
               subparagraph (iv), in case the Corporation shall
               pay or make a dividend or other distribution on its
               Common Stock consisting of evidences of its
               indebtedness, shares of any class of capital stock
               or assets (including securities, but excluding any
               rights or warrants referred to in subparagraph (ii)
               of this Section 6(c), and excluding any dividend or
               distribution (x) in connection with the
               liquidation, dissolution or winding up of the
               Corporation, whether voluntary or involuntary,
               (y) paid exclusively in cash or (z) referred to in
               subparagraph (i) of this Section 6(c)) (any of the
               foregoing being hereinafter in this subparagraph (iv) called 
               the "Securities"), then, in each such case, unless the 
               Corporation elects to reserve such Securities for 
               distribution to the holders of the Convertible Preferred

               Stock upon the conversion of the shares of Convertible 
               Preferred Stock so that any such holder converting shares 
               of Convertible Preferred Stock will receive upon such 
               conversion, in addition to the shares of the Common Stock to
               which such holder is entitled, the amount and kind
               of such Securities which such holder would have
               received if such holder had, immediately prior to
               the record date for the determination of
               stockholders entitled to receive such distribution
               of the Securities, converted its shares of
               Convertible Preferred Stock into Common Stock, the
               conversion price shall be reduced so that the same
               shall equal the price determined by multiplying the
               conversion price in effect on the date fixed for
               determination of stockholders of record entitled to
               receive such Securities by a fraction of which the
               numerator shall be the current market price per
               share (determined as provided in subparagraph (v)
               of this Section 6(c)) of the Common Stock on the
               date fixed for such determination less the fair
               market value (as determined by the Board of
               Directors or, to the extent permitted by applicable
               law, a duly authorized committee thereof, whose
               determination shall be conclusive and described in
               a resolution of the Board of Directors or such duly
               authorized committee thereof, as the case may be),
               on the date fixed for such determination, of the
               portion of the Securities so distributed applicable
               to one share of Common Stock and the denominator
               shall be such current market price per share of the
               Common Stock on the date fixed for such
               determination, such reduction to become effective
               immediately prior to the opening of business on the
               day following the date fixed for such
               determination; provided, however, that in the event
               the then fair market value (as so determined) of
               the portion of the Securities so distributed
               applicable to one share of Common Stock is equal to
               or greater than the current market price per share
               (as defined in subparagraph (v) of this
               Section 6(c)) of the Common Stock on the date fixed
               for such determination, in lieu of the foregoing
               adjustment, adequate provision shall be made so
               that each holder of shares of Convertible Preferred
               Stock shall have the right to receive upon
               conversion the amount and kind of Securities such
               holder would have received had he converted each
               such share of Convertible Preferred Stock on the
               date fixed for determination of stockholders
               entitled to receive such Securities.  In the event
               that such dividend or distribution is not so paid
               or made, the conversion price shall again be
               adjusted to be the conversion price which would
               then be in effect if such dividend or distribution
               had not occurred.  To the extent that such
               Securities consist of any rights or warrants (other
               than those referred to in subparagraph (ii) of this
               Section 6(c)) and the evidences of indebtedness,
               shares or assets issuable on exercise thereof are not

               delivered after the expiration of such rights or
               warrants, the conversion price shall be readjusted to the 
               conversion price which would then be in effect had the 
               adjustments made upon the issuance of such rights or warrants 
               been made on the basis of delivery of only the evidences of
               indebtedness, shares or assets actually delivered. 
               If the Board of Directors (or, to the extent
               permitted by applicable law, a duly authorized
               committee thereof) determines the fair market value
               of any distribution for purposes of this
               subparagraph (iv) by reference to the actual or
               when issued trading market for any securities
               comprising such distribution, it must in doing so
               consider the prices in such market over the same
               period used in computing the current market price
               per share of Common Stock pursuant to subparagraph
               (v) of this Section 6(c).  

                      (v)  For the purpose of any computation
               under subparagraphs (ii) and (iv) of this
               Section 6(c) and under Section 6(h), the current
               market price per share of Common Stock on any date
               shall be deemed to be the average of the daily
               Closing Prices (as defined in Section 6(i)) for the
               ten consecutive Trading Days prior to and including
               the date in question; provided, however, that
               (1) if the "ex" date (as hereinafter defined) for
               any event (other than the issuance, distribution or
               Fundamental Change requiring such computation) that
               requires an adjustment to the conversion price
               pursuant to subparagraph (i), (ii), (iii) or (iv)
               above or Section 6(h) occurs during such ten
               consecutive Trading Days and prior to the "ex" date
               for the issuance, distribution or Fundamental
               Change requiring such computation, the Closing
               Price for each Trading Day prior to the "ex" date
               for such other event shall be adjusted by
               multiplying such Closing Price by the same fraction
               by which the conversion price is so required to be
               adjusted as a result of such other event, (2) if
               the "ex" date for any event (other than the
               issuance, distribution or Fundamental Change
               requiring such computation) that requires an
               adjustment to the conversion price pursuant to
               subparagraph (i), (ii), (iii) or (iv) above or
               Section 6(h) occurs on or after the "ex" date for
               the issuance, distribution or Fundamental Change
               requiring such computation and on or prior to the
               date in question, the Closing Price for each
               Trading Day on and after the "ex" date for such
               other event shall be adjusted by multiplying such
               Closing Price by the reciprocal of the fraction by
               which the conversion price is so required to be
               adjusted as a result of such other event (provided
               that in the event that such fraction is required to
               be determined at a date subsequent to the date in question 
               and with reference to events taking place subsequent to 
               the date in question, the Board of Directors or, to the

               extent permitted by applicable law, a duly authorized 
               committee thereof, whose determination shall be conclusive and 
               described in a resolution of the Board of Directors or such 
               duly authorized committee thereof, as the case may be,
               shall estimate such fraction based on assumptions
               it deems reasonable regarding such events taking
               place subsequent to the date in question, and such
               estimated fraction shall be used for purposes of
               such adjustment until such time as the actual

               fraction by which the conversion price is so
               required to be adjusted as a result of such other
               event is determined), and (3) if the "ex" date for
               the issuance, distribution or Fundamental Change
               requiring such computation is on or prior to the
               date in question, after taking into account any
               adjustment required pursuant to clause (1) or (2)
               of this proviso, the Closing Price for each Trading
               Day on or after such "ex" date shall be adjusted by
               adding thereto the amount of any cash and the fair
               market value (as determined by the Board of
               Directors or, to the extent permitted by applicable
               law, a duly authorized committee thereof in a
               manner consistent with any determination of such
               value for purposes of paragraph (iv) of this
               Section 6(c), whose determination shall be
               conclusive and described in a resolution of the
               Board of Directors or such duly authorized
               committee thereof, as the case may be) of the
               evidence of indebtedness, shares of capital stock
               or assets being distributed applicable to one share
               of Common Stock as of the close of business on the
               day before such "ex" date.  For purposes of this
               paragraph, the term "ex" date, (1) when used with
               respect to any issuance, distribution or
               Fundamental Change, means the first date on which
               the Common Stock trades regular way on the relevant
               exchange or in the relevant market from which the
               Closing Price was obtained without the right to
               receive such issuance, such distribution or the
               cash, securities, property or other assets
               distributable in such Fundamental Change to holders
               of the Common Stock, and (2) when used with respect
               to any subdivision or combination of shares of
               Common Stock, means the first date on which the
               Common Stock trades regular way on such exchange or
               in such market after the time at which such
               subdivision or combination becomes effective.

                      (vi)  The Corporation may make such
               reduction in the conversion price, in addition to
               those required by subparagraphs (i), (ii), (iii)
               and (iv) of this Section 6(c) or by Section 6(h),
               as it considers to be advisable to avoid or
               diminish any income tax to holders of Common Stock
               or rights to purchase Common Stock resulting from
               any dividend or distribution of stock (or rights to
               acquire stock) or from any event treated as 
               such for income tax purposes.  To the extent permitted by 
               
                               -13-
<PAGE>

               
               law, the Corporation from time to time may reduce the 
               conversion price by any amount for any period of 
               time if the period is at least twenty days, the reduction 
               is irrevocable during the period and the Board of Directors 
               (or, to the extent permitted by applicable law, a duly
               authorized committee thereof) shall have made a
               determination that such reduction would be in the
               best interests of the Corporation, which
               determination shall be conclusive.  Whenever the
               conversion price is reduced pursuant to the
               preceding sentence, the Corporation shall mail to
               holders of record of the Convertible Preferred
               Stock a notice of the reduction at least fifteen
               days prior to the date the reduced conversion price
               takes effect, and such notice shall state the
               reduced conversion price and the period it will be
               in effect.

                      (vii)  No adjustment in the conversion price
               shall be required unless such adjustment would
               require an increase or decrease of at least 1% in
               the conversion price; provided, however, that any
               adjustments which by reason of this subparagraph
               (vii) are not required to be made shall be carried
               forward and taken into account in determining
               whether any subsequent adjustment shall be
               required.

                      (viii)  Notwithstanding any other provision
               of this Section 6, no adjustment to the conversion
               price shall reduce the conversion price below the
               then par value per share of the Common Stock, and
               any such purported adjustment shall instead reduce
               the conversion price to such par value.  The
               Corporation hereby covenants not to take any action
               (1) to increase the par value per share of the
               Common Stock or (2) that would or does result in
               any adjustment in the conversion price that, if
               made without giving effect to the previous
               sentence, would cause the conversion price to be
               less than the then par value per share of the
               Common Stock; provided however, that the covenant
               in this sentence shall be suspended if within ten
               days of determining in good faith that such action
               would result in such adjustment (but not later than
               the business day following the effectiveness of
               such adjustment), the Corporation gives notice of
               redemption of all outstanding shares of the
               Convertible Preferred Stock, and effects the
               redemption referred to in such notice on the
               redemption date referred to therein in compliance
               with Section 5, but the covenant in this sentence
               shall be retroactively reinstated if such notice or
               redemption does not occur.

                      (ix)  Whenever the conversion price is
               adjusted as herein provided:

                               -14-
<PAGE>


                      (1)  the Corporation shall compute the adjusted 
                      conversion price and shall prepare a certificate 
                      signed by the Treasurer of the Corporation setting forth 
                      the adjusted conversion price and showing in reasonable
                      detail the facts upon which such adjustment
                      is based, and such certificate shall
                      forthwith be filed with the transfer agent
                      for the Convertible Preferred Stock; and

                      (2)  a notice stating the conversion price
                      has been adjusted and setting forth the
                      adjusted conversion price shall as soon as
                      practicable be mailed by the Corporation to
                      all record holders of shares of Convertible
                      Preferred Stock at their last addresses as
                      they shall appear upon the stock transfer
                      books of the Corporation.

                      (x)  In any case in which this subparagraph
               (c) provides that an adjustment shall become
               effective immediately after a record date for an
               event, the Corporation may defer until the
               occurrence of such event (y) issuing to the holder
               of any share of Convertible Preferred Stock
               converted after such record date and before the
               occurrence of such event the additional shares of
               Common Stock issuable upon such conversion by
               reason of the adjustment required by such event
               over and above the Common Stock issuable upon such
               conversion before giving effect to such adjustment
               and (z) paying to such holder any amount in cash in
               lieu of any fractional share of Common Stock
               pursuant to subparagraph (d) of this Section 6.

               (d)    No Fractional Shares.  No fractional shares
          or scrip representing fractional shares of Common Stock
          shall be issued upon conversion of Convertible Preferred
          Stock.  If more than one certificate evidencing shares of
          Convertible Preferred Stock shall be surrendered for
          conversion at one time by the same holder, the number of
          full shares issuable upon conversion thereof shall be
          computed on the basis of the aggregate number of shares
          of Convertible Preferred Stock so surrendered.  Instead
          of any fractional share of Common Stock that would
          otherwise be issuable upon conversion of any shares of
          Convertible Preferred Stock, the Corporation shall pay a
          cash adjustment in respect of such fractional interest in
          an amount equal to the same fraction of the market price
          per share of Common Stock (as determined or prescribed by
          the Board of Directors or, to the extent permitted by applicable 
          law, a duly authorized committee thereof), which, so long 
          as the Common Stock is listed on the New York Stock Exchange, 
          shall be the Closing Price on the New York Stock Exchange at 
          the close of business on the Trading Day immediately preceding 
          the date of conversion.

               (e)    Reclassification, Consolidation, Merger or
          Sale of Assets.  In the event that the Corporation shall
          be a party to any transaction constituting a
          recapitalization, reclassification, consolidation,
          merger, sale or transfer of all or substantially all of
          its assets or share exchange (including without
          limitation any (i) recapitalization or reclassification
          of the Common Stock (other than a change in par value, or
          from par value to no par value, or from no par value to
          par value, or as a result of a subdivision or combination
          of the Common Stock)), (ii) any consolidation of the
          Corporation with, or merger of the Corporation into, any
          other person, any merger of another person into the
          Corporation (other than a merger which does not result in
          a reclassification, conversion, exchange or cancellation
          of outstanding shares of Common Stock of the
          Corporation), (iii) any sale or transfer of all or
          substantially all of the assets of the Corporation, or
          (iv) any compulsory share exchange pursuant to which the
          Common Stock is converted into the right to receive other
          securities, cash or other property), then lawful
          provision shall be made as part of the terms of such
          transaction whereby the holder of each share of
          Convertible Preferred Stock then outstanding shall have
          the right thereafter, to convert such share only into
          (1) in the case of a Non-Stock Fundamental Change (as
          defined in Section 6(i)) and subject to funds being
          legally available for such purpose under applicable law
          at the time of such conversion, the kind and amount of
          securities, cash and other property receivable upon such
          recapitalization, reclassification, consolidation,
          merger, sale, transfer or share exchange by a holder of
          the number of shares of Common Stock into which such
          share of Convertible Preferred Stock might have been
          converted immediately prior to such recapitalization,
          reclassification, consolidation, merger, sale, transfer
          or share exchange, after giving effect, in the case of
          any Non-Stock Fundamental Change, to any adjustment in
          the conversion price required by the provisions of
          Section 6(h), and (2) in the case of a Common Stock
          Fundamental Change (as defined in Section 6(i)), into
          common stock of the kind received by holders of Common
          Stock as a result of such Common Stock Fundamental Change
          in an amount determined pursuant to the provisions of
          Section 6(h).  The Corporation or the person formed by
          such consolidation or resulting from such merger or which
          acquires such assets or which acquires the Corporation's
          shares, as the case may be, shall make provisions in its
          certificate or articles of incorporation or other
          constituent document to establish such right.  Such
          certificate or articles of incorporation or other
          constituent document shall provide for adjustments which,
          for events subsequent to the effective date of such
          certificate or articles of incorporation or other constituent 
          document, shall be as nearly equivalent as may be practicable to the 
          adjustments provided for in this Section 6.  The above 
          provisions shall similarly apply to successive 
          
                               -16-

          recapitalizations, reclassifications, consolidations, mergers, 
          sales, transfer or share exchanges.

               (f)    Reservation of Shares; Transfer Taxes; Etc. 
          The Corporation shall at all times reserve and keep
          available, out of its authorized and unissued stock,
          solely for the purpose of effecting the conversion of the
          Convertible Preferred Stock, such number of shares of its
          Common Stock (and associated Preferred Stock Purchase
          Rights) free of preemptive rights as shall from time to
          time be sufficient to effect the conversion of all shares
          of Convertible Preferred Stock from time to time
          outstanding.  The Corporation shall from time to time, in
          accordance with the laws of the State of Delaware, use
          its best efforts to increase the authorized number of
          shares of Common Stock (and associated Preferred Stock
          Purchase Rights) if at any time the number of shares of
          authorized and unissued Common Stock (and associated
          Preferred Stock Purchase Rights) shall not be sufficient
          to permit the conversion of all the then outstanding
          shares of Convertible Preferred Stock.

               If any shares of Common Stock required to be
          reserved for purposes of conversion of the Convertible
          Preferred Stock hereunder require registration with or
          approval of any governmental authority under any federal
          or state law before such shares may be issued upon
          conversion, the Corporation will in good faith and as
          expeditiously as possible endeavor to cause such shares
          to be duly registered or approved, as the case may be. 
          If the Common Stock is listed on the New York Stock
          Exchange or any other national securities exchange, the
          Corporation will, in good faith and as expeditiously as
          possible, endeavor, if permitted by the rules of such
          exchange, to list and keep listed on such exchange, upon
          official notice of issuance, all shares of Common Stock
          issuable upon conversion of the Convertible Preferred
          Stock.

               The Corporation shall pay any and all issue or other
          taxes that may be payable in respect of any issue or
          delivery of shares of Common Stock upon conversion of the
          Convertible Preferred Stock.  The Corporation shall not,
          however, be required to pay any tax which may be payable
          in respect of any transfer involved in the issue or
          delivery of Common Stock (or other securities or assets)
          in a name other than that in which the shares of
          Convertible Preferred Stock so converted were registered,
          and no such issue or delivery shall be made unless and
          until the person requesting such issue has paid to the
          Corporation the amount of such tax or has established, to
          the satisfaction of the Corporation, that such tax has
          been paid.

               (g)    Prior Notice of Certain Events.  In case:

                      (i)  the Corporation shall (1) declare any dividend 
               (or any other distribution) on its Common Stock, other 
                               -17-

               than (A) a dividend payable in shares of Common Stock or 
               (B) a dividend payable in cash out of its retained 
               earnings other than any special or nonrecurring or other 
               extraordinary dividend or (2) declare or authorize a 
               redemption or repurchase of in excess of 10% of the then 
               outstanding shares of Common Stock; or

                      (ii)  the Corporation shall authorize the
               granting to all holders of Common Stock of rights
               or warrants to subscribe for or purchase any shares
               of stock of any class or of any other rights or
               warrants (other than Preferred Stock Purchase
               Rights); or

                      (iii)  of any reclassification of Common
               Stock (other than a subdivision or combination of
               the outstanding Common Stock, or a change in par
               value, or from par value to no par value, or from
               no par value to par value), or of any consolidation
               or merger to which the Corporation is a party and
               for which approval of any stockholders of the
               Corporation shall be required, or of the sale or
               transfer of all or substantially all of the assets
               of the Corporation or of any compulsory share
               exchange whereby the Common Stock is converted into
               other securities, cash or other property; or

                      (iv)  of the voluntary or involuntary
               dissolution, liquidation or winding up of the
               Corporation;

          then the Corporation shall cause to be filed with the
          transfer agent for the Convertible Preferred Stock and
          shall cause to be mailed to the holders of record of the
          Convertible Preferred Stock, at their last addresses as
          they shall appear upon the stock transfer books of the
          Corporation, at least fifteen days prior to the
          applicable record date hereinafter specified, a notice
          stating (x) the date on which a record (if any) is to be
          taken for the purpose of such dividend, distribution,
          redemption, repurchase or granting of rights or warrants
          or, if a record is not be taken, the date as of which the
          holders of Common Stock of record to be entitled to such
          dividend, distribution, redemption, rights or warrants
          are to be determined or (y) the date on which such
          reclassification, consolidation, merger, sale, transfer,
          share exchange, dissolution, liquidation or winding up is
          expected to become effective, and the date as of which it
          is expected that holders of Common Stock of record shall
          be entitled to exchange their shares of Common Stock for
          securities or other property deliverable upon such reclassification, 
          consolidation, merger, sale, transfer, share exchange,  dissolution, 
          liquidation or winding up (but no failure to mail 
          such notice or any defect therein or in the mailing thereof 
          shall affect the validity of the corporate action required to 
          be specified in such notice).

          (h)  Adjustments in Case of Fundamental Changes. 
Notwithstanding any other provision in this Section 6 to the
contrary, if any Fundamental Change (as defined in Section 6(i))
occurs, then the conversion price in effect will be adjusted
immediately after such Fundamental Change as described below.  In
addition, in the event of a Common Stock Fundamental Change, each
share of Convertible Preferred Stock shall be convertible solely
into common stock of the kind received by holders of Common Stock
as the result of such Common Stock Fundamental Change.

          For purposes of calculating any adjustment to be made
pursuant to this Section 6(h) in the event of a Fundamental Change,
immediately after such Fundamental Change (and for such purposes a
Fundamental Change shall be deemed to occur on the earlier of (a)
the occurrence of such Fundamental Change and (b) the date, if any,
fixed for determination of stockholders entitled to receive the
cash, securities, property or other assets distributable in such
Fundamental Change to holders of the Common Stock):

               (i)  in the case of a Non-Stock Fundamental Change,
          the conversion price of the Convertible Preferred Stock
          shall become the lower of (A) the conversion price in
          effect immediately prior to such Non-Stock Fundamental
          Change, but after giving effect to any other adjustments
          effected pursuant to this Section 6, and (B) the product
          of (1) the greater of the Applicable Price (as defined in
          Section 6(i)) or the then applicable Reference Market
          Price (as defined in Section 6(i)) and (2) a fraction the
          numerator of which shall be $50.00 and the denominator of
          which shall be the then current Redemption Price per
          share of Convertible Preferred Stock if the redemption
          date were the date of such Non-Stock Fundamental Change
          (such denominator being the sum of (x) the product of
          $50.00 and the percentage (expressed as a decimal) set
          forth in the table contained in Section 5(a) above, or
          the percentage determined as follows:  if the Non-Stock
          Fundamental Change occurs during the period commencing on
          the Date of Original Issue of the Convertible Preferred
          Stock and ending July 14, 1993, 107.0% and for the
          12-month periods commencing July 15, 1993, 1994, and
          1995, 106.3%, 105.6%, and 104.9%, respectively, and
          (y) any accrued and unpaid dividends thereon, whether or
          not declared, to but excluding the date of such Non-Stock
          Fundamental Change); and

               (ii)  in the case of a Common Stock Fundamental
          Change, the conversion price of the Convertible Preferred
          Stock shall be the conversion price in effect immediately
          prior to such Common Stock Fundamental Change, but after
          giving effect to any other adjustments effected pursuant
          to this Section 6, multiplied by a fraction, the


                               -19-
<PAGE>          
          

          numerator of which is the Purchaser Stock Price (as
          defined in Section 6(i)) and the denominator of which is
          the Applicable Price; provided, however, that in the
          event of a Common Stock Fundamental Change in which
          (A) 100% by value of the consideration received by a
          holder of Common Stock is common stock of the successor,
          acquiror or other third party (except for cash, if any,
          paid with respect to any fractional interests in such
          common stock resulting from such Common Stock Fundamental
          Change) and (B) all of the Common Stock shall have been
          exchanged for, converted into or acquired for common
          stock (and cash, if any, with respect to fractional
          interests) of the successor, acquiror or other third
          party, the conversion price of the shares of Convertible
          Preferred Stock immediately following such Common Stock
          Fundamental Change shall be the conversion price in
          effect immediately prior to such Common Stock Fundamental
          Change multiplied by a fraction, the numerator of which
          is one (1) and the denominator of which is the number of
          shares of common stock of the successor, acquiror, or
          other third party received by a holder of one share of
          Common Stock as a result of such Common Stock Fundamental
          Change.

          (i)  Definitions.  The following definitions shall apply
       to terms used in this Section 6:

               (1)  "Applicable Price" shall mean (i) in the event
          of a Non-Stock Fundamental Change in which the holders of
          the Common Stock receive only cash, the amount of cash
          received by the holder of one share of Common Stock and
          (ii) in the event of any other Non-Stock Fundamental
          Change or any Common Stock Fundamental Change, the
          average of the Closing Prices for one share of the Common
          Stock during the ten Trading Days immediately prior to
          the record date for the determination of the holders of
          Common Stock entitled to receive cash, securities,
          property or other assets in connection with such
          Non-Stock Fundamental Change or Common Stock Fundamental
          Change or, if there is no such record date, prior to the
          date upon which the holders of the Common Stock shall
          have the right to receive such cash, securities, property
          or other assets.  The Closing Price on any Trading Day
          may be subject to adjustment as provided in Section
          6(c)(v).

               (2)  "Closing Price" with respect to any securities
          on any day shall mean the closing sale price, regular
          way, on such day or, in case no such sale takes place on
          such day, the average of the reported closing bid and
          asked prices, regular way, in each case on the New York
          Stock Exchange or, if such security is not listed or
          admitted to trading on such Exchange, on the principal
          
                               -20-

          national securities exchange or quotation system on which
          such security is quoted or listed or admitted to trading
          or, if not quoted or listed or admitted to trading on any
          national securities exchange or quotation system, the
          average of the closing bid and asked prices of such
          security on the over-the-counter market on the date in
          question as reported by the National Quotation Bureau
          Incorporated, or a similarly generally accepted reporting
          service, or if not so available, in such manner as
          furnished by any New York Stock Exchange member firm
          selected from time to time by the Board of Directors for
          that purpose or a price determined in good faith by the
          Board of Directors.  The Closing Price on any Trading Day
          may be subject to adjustment as provided in Section
          6(c)(v).

               (3)  "Common Stock Fundamental Change" shall mean
          any Fundamental Change in which more than 50% by value
          (as determined in good faith by the Board of Directors of
          the Corporation or, to the extent permitted by applicable
          law, a duly authorized committee thereof) of the
          consideration received by the holders of Common Stock
          pursuant to such transaction consists of common stock
          that, for the consecutive ten Trading Days immediately
          prior to such Fundamental Change, has been admitted for
          listing or admitted for listing subject to notice of
          issuance on a national securities exchange or quoted on
          the National Association of Securities Dealers, Inc.
          ("NASDAQ") National Market System; provided, however,
          that a Fundamental Change shall not be a Common Stock
          Fundamental Change unless either (i) the Corporation
          continues to exist after the occurrence of such
          Fundamental Change and the outstanding shares of
          Convertible Preferred Stock continue to exist as
          outstanding shares of Convertible Preferred Stock, or
          (ii) not later than the occurrence of such Fundamental
          Change, the outstanding shares of Convertible Preferred
          Stock are converted into or exchanged for shares of
          convertible preferred stock of a corporation succeeding
          to the business of the Corporation, which convertible
          preferred stock has powers, preferences and relative,
          participating, optional or other rights, and
          qualifications, limitations and restrictions
          substantially similar to those of the Convertible
          Preferred Stock.

               (4)  "Fundamental Change" shall mean the occurrence
          of any transaction or event or series of transactions or
          events pursuant to which all or substantially all of the
          Common Stock shall be exchanged for, converted into,
          acquired for or constitute solely the right to receive
          cash, securities, property or other assets (whether by
          means of an exchange offer, liquidation, tender offer,
          
                               -21-
<PAGE>          
          
          
          consolidation, merger, combination, reclassification,
          recapitalization or otherwise); provided, however, in the
          case of any series of transactions or events, for
          purposes of adjustment of the conversion price such
          Fundamental Change shall be deemed to have occurred when
          substantially all of the Common Stock of the Corporation
          shall be exchanged for, converted into, or acquired for
          or constitute solely the right to receive cash,
          securities, property or other assets, but the adjustment
          shall be based upon the consideration which the holders
          of Common Stock received in such transaction or event as
          a result of which more than 50% of the Common Stock of
          the Corporation shall have been exchanged for, converted
          into, or acquired for or constitute solely the right to
          receive cash, securities, property or other assets;
          provided, further, that such term does not include
          (i) any such transaction or event in which the
          Corporation and/or any of its subsidiaries are the
          issuers of all the cash, securities, property or other
          assets exchanged, acquired or otherwise issued in such
          transaction or event, or (ii) any such transaction or
          event in which the holders of Common Stock receive
          securities of an issuer other than the Corporation if,
          immediately following such transaction or event, such
          holders hold a majority of the securities having the
          power to vote normally in the election of directors of
          such other issuer outstanding immediately following such
          transaction or other event.

               (5)  "Non-Stock Fundamental Change" shall mean any
          Fundamental Change other than a Common Stock Fundamental
          Change.

               (6)  "Purchaser Stock Price" shall mean, with
          respect to any Common Stock Fundamental Change, the
          average of the Closing Prices for one share of the common
          stock received in such Common Stock Fundamental Change
          during the ten Trading Days immediately prior to the
          record date for the determination of the holders of
          Common Stock entitled to receive such common stock, or if
          there is no such record date, the date upon which the
          holders of the Common Stock shall have the right to
          receive such common stock.  The Closing Price on any
          Trading Day may be subject to adjustment as provided in
          Section 6(c)(v).

               (7)  "Reference Market Price" shall initially mean
          $17.00 (which is an amount equal to 66 2/3% of the
          reported last sales price for the Common Stock on the New
          York Stock Exchange on July 20, 1992), and in the event
          of any adjustment to the conversion price other than as
          a result of a Fundamental Change, the Reference Market
          Price shall also be adjusted so that the ratio of the
          
                               -22-
<PAGE>

          Reference Market Price to the conversion price after
          giving effect to any such adjustment shall always be the
          same as the ratio of $17.00 to the initial conversion
          price set forth in Section 6(a) above.

               (8)  "Trading Day" shall mean (x) if the applicable
          security is listed or admitted for trading on the New
          York Stock Exchange or another national securities
          exchange, a day on which the New York Stock Exchange or
          such other national securities exchange is open for
          business or (y) if the applicable security is quoted on
          the National Market System of the NASDAQ, a day on which
          trade may be made on such National Market System or
          (z) if the applicable security is not otherwise listed,
          admitted for trading or quoted, any day other than a
          Saturday or Sunday or a day on which banking institutions
          in the State of New York are authorized or obligated by
          law or executive order to close.

          (j)  Dividend or Interest Reinvestment Plans:  Other. 
Notwithstanding the foregoing provisions, the issuance of any
shares of Common Stock pursuant to any plan providing for the
reinvestment of dividends or interest payable on securities of the
Corporation and the investment of additional optional amounts in
shares of Common Stock under any such plan, and the issuance of any
shares of Common Stock or options or rights to purchase such shares
pursuant to any employee benefit plan or program of the Corporation
or pursuant to any option, warrant, right or exercisable,
exchangeable or convertible security outstanding as of the date the
Convertible Preferred Stock was first designated (except as
expressly provided in Section 6(c)(ii) with respect to certain
events under the Rights Agreement, dated as of January 29, 1990,
between the Corporation and Manufacturers Hanover Trust Company of
California (the "Rights Agreement")), and any issuance of Preferred
Stock Purchase Rights, shall not be deemed to constitute an
issuance of Common Stock or exercisable, exchangeable or
convertible securities by the Corporation to which any of the
adjustment provisions described above applies.  There shall also be
no adjustment of the conversion price in case of the issuance of
any stock (or securities convertible into exchangeable for stock)
of the Corporation except as specifically described in this
Section 6.  Except as expressly set forth above, if any action
would require adjustment of the conversion price pursuant to more
than one of the provisions described above, only one adjustment
shall be made and such adjustment shall be the amount of adjustment
which has the highest absolute value.

          (k)  Preferred Stock Purchase Rights.  

               (i)  So long as Preferred Stock Purchase Rights of
          a kind similar to those declared and distributed by the

                               -23-
<PAGE>

          Corporation's Board of Directors in January 1990, as the
          same may hereafter be amended or reissued ("Preferred
          Stock Purchase Rights"), are attached to the outstanding
          shares of Common Stock of the Corporation, each share of
          Common Stock issued upon conversion of the shares of
          Convertible Preferred Stock prior to the earliest of any
          Distribution Date (as defined in the Rights Agreement),
          the date of redemption of the Preferred Stock Purchase
          Rights or the date of expiration of the Preferred Stock
          Purchase Rights shall be issued with Preferred Stock
          Purchase Rights in a number equal to the number of
          Preferred Stock Purchase Rights then attached to each
          such outstanding share of Common Stock.

               (ii)  For the purposes of Section 6(c)(ii), upon the
          earlier to occur of (x) the eleventh Business Day (as
          such term is defined in the Rights Agreement) following
          a 15% Ownership Date (as such term is defined in the
          Rights Agreement) and (y) a Section 13(a) Event (as such
          term is defined in the Rights Agreement), then an
          issuance of rights to purchase shares of Common Stock
          during a period not exceeding 45 days from the date of
          such dividend or other distribution shall be deemed to
          have occurred, unless a Redemption Date or an Expiration
          Date (as such terms are defined in the Rights Agreement)
          has occurred prior to such eleventh Business Day or such
          Section 13(a) Event, as the case may be, or unless the
          Company has taken action pursuant to Section 7(e) of the
          Rights Agreement to substitute other consideration for
          all or any portion of the Series A Junior Participating
          Cumulative Preferred Stock otherwise issuable upon
          exercise of a Preferred Stock Purchase Right.  For
          purposes of the reduction of the conversion price
          provided for in Section 6(c)(ii) upon such deemed
          issuance of rights, each share of Series A Junior
          Participating Cumulative Preferred Stock shall be deemed
          to constitute 100 shares of Common Stock (subject to
          adjustment as provided in the Rights Plan), and the date
          fixed for determination of stockholders entitled to
          receive such rights shall be the close of business on the
          tenth such Business Day following such 15% Ownership Date
          or the date of such Section 13(a) Event, as the case may
          be; provided, however, that the current market price per
          share of the Common Stock shall be determined based on
          the ten consecutive trading days prior to and including
          the Distribution Date.  

               (iii)  For the purposes of Section 6(c)(iv), if the
          Company has taken action pursuant to Section 7(e) of the
          Rights Agreement to substitute other consideration for
          all or any portion of the Series A Junior Participating
          Cumulative Preferred Stock otherwise issuable upon
          exercise of a Preferred Stock Purchase Right, upon the

                               -24-
<PAGE>
          
          
          earlier to occur of (x) the eleventh Business Day
          following a 15% Ownership Date and (y) a Section 13(a)
          Event, then an issuance of Securities shall be deemed to
          have occurred, unless a Redemption Date or an Expiration
          Date has occurred prior to such eleventh Business Day or
          such Section 13(a) Event, as the case may be.  For
          purposes of the reduction of the conversion price
          provided for in Section 6(c)(iv) upon such deemed
          issuance of Securities, the date fixed for determination
          of stockholders entitled to receive such rights shall be
          the close of business on the tenth such Business Day
          following such 15% Ownership Date or the date of such
          Section 13(a) Event, as the case may be; provided,
          however, that the current market price per share of the
          Common Stock shall be determined based on the ten
          consecutive trading days prior to and including the
          Distribution Date.

               (iv)  For purposes of Section 6(c)(ii) and Section
          6(c)(iv), the redemption by the Corporation of Preferred
          Stock Purchase Rights shall be deemed to be an expiration
          of such rights.

               (v)  If any Convertible Preferred Stock has been
          converted on or after the Distribution Date and on or
          before the tenth Business Day following such 15%
          Ownership Date or the date of such Section 13(a) Event,
          as the case may be, then as soon as practicable following
          the date on which the adjustment required by subsection
          (ii) or (iii) of this Section 6(k) is made, the
          Corporation shall issue to the holder of the Convertible
          Preferred Stock so converted a number of additional
          shares of Common Stock (and cash in lieu of any
          fractional share) that would have been issuable upon such
          conversion had such adjustment been made immediately
          prior to such conversion. 

          (l)  Exclusion of Treasury Shares.  For purposes of this
Section 6, the number of shares of Common Stock at any time
outstanding shall not include any shares of Common Stock then owned
or held by or for the account of the Corporation.

          (m)  Special Provisions Regarding Adjustment of
Conversion Price.  In the event that the provisions hereof
specifying the methods by which the conversion price is adjusted
would require a conversion price adjustment that is determined in
good faith by the Board of Directors of the Corporation or, to the
extent permitted by applicable law, a duly authorized committee
thereof to be inconsistent with the purposes of the provisions
hereof providing for conversion price adjustments (generally, to place the 
holders of the Convertible Preferred Stock in a position equivalent to the 
position they were in prior to the event requiring an 

                               -25-
<PAGE>


adjustment to the conversion price), the Board of Directors of 
the Corporation or, to the extent permitted by applicable law, 
a duly authorized committee thereof may determine
an adjustment (in lieu of that required pursuant to such
provisions) that it determines in good faith to be consistent with
such purposes, which determination shall be conclusive and
described in a resolution of the Board of Directors or such duly
authorized committee thereof, as the case may be.

          7.   Voting Rights

          (a)  General.  The holders of Convertible Preferred Stock
will not have any voting rights except as set forth below or as
otherwise from time to time required by law.  In connection with
any right to vote, each holder of Convertible Preferred Stock will
have one vote for each such share held.  Any shares of Convertible
Preferred Stock held by the Corporation or any entity controlled by
the Corporation shall not have voting rights hereunder and shall
not be counted in determining the presence of a quorum.

          (b)  Default Voting Rights.  Whenever dividends on the
Convertible Preferred Stock or any other class or series of the
Corporation's preferred stock hereafter issued ranking, as to
dividends, on a parity with the Convertible Preferred Stock shall
be in arrears in an aggregate amount equal to at least six
quarterly dividends (whether or not consecutive), (i) the number of
members of the Board of Directors shall be increased by two,
effective as of the time of election of such directors and (ii) the
holders of the Convertible Preferred Stock (voting separately as a
class with all other affected classes or series of preferred stock
upon which like voting rights have been conferred and are
exercisable) will have the exclusive right to vote for and elect
such two additional directors of the Corporation.  The right of the
holders of the Convertible Preferred Stock to vote for such two
additional directors shall terminate when all accrued and unpaid
dividends on the Convertible Preferred Stock have been declared and
paid or set apart for payment.  The term of office of all directors
so elected shall terminate immediately upon the termination of the
right of the holders of the Convertible Preferred Stock and such
other preferred stock to vote for such two additional directors. 
Each such director so elected shall serve until the next annual
meeting and until his successor is elected, unless his term of
office is terminated earlier as provided in the preceding sentence.

          The foregoing right of the holders of the Convertible
Preferred Stock with respect to the election of two directors may be exercised 
at the next annual meeting of stockholders following the default or at any 
special meeting of stockholders held for such purpose.  If the right to elect 
directors shall have accrued to the holders of the Convertible 

                               -26-

Preferred Stock more than ninety days preceding the date 
established for the next annual meeting of stockholders, 
the President of the Corporation shall, within twenty
days after the delivery to the Corporation at its principal office
of a written request for a special meeting signed by the holders of
at least 10% of all outstanding shares of the Convertible Preferred
Stock, call a special meeting of the holders of the Convertible
Preferred Stock to be held within sixty days after the delivery of
such request for the purpose of electing such additional directors.

          The holders of the Convertible Preferred Stock and such
other preferred stock referred to above voting as a class shall
have the exclusive right to remove without cause at any time and
replace any directors such holders shall have elected pursuant to
this Section 7.

          (c)  Class Voting Rights.  So long as the Convertible
Preferred Stock is outstanding, the Corporation shall not, without
the affirmative vote or consent of the holders of at least 66-2/3%
(or such higher percentage, if any, as may then be required by
applicable law) (i) of all outstanding shares of the Convertible
Preferred Stock, voting separately as a class, amend, alter or
repeal any provision of the Certificate of Incorporation or the By-
Laws of the Corporation, so as to affect adversely the relative
rights, preferences, qualifications, limitations or restrictions of
the Convertible Preferred Stock or (ii) of all outstanding shares
of the Convertible Preferred Stock and any other series of
preferred stock of the Corporation ranking on a parity with the
Convertible Preferred Stock either as to dividends or upon
liquidation, voting as a single class without regard to series,
create, authorize or issue, or reclassify any authorized stock of
the Corporation into, or increase the authorized amount of, any
preferred stock of the Corporation ranking senior to the
Convertible Preferred Stock as to dividend or liquidation rights,
or any security convertible into such stock.  A class vote on the
part of the Convertible Preferred Stock shall, without limitation,
specifically not be required (except as otherwise required by law
or resolution of the Board of Directors) in connection with: (a)
the authorization, issuance or increase in the authorized amount of
any shares of any other class or series of stock which ranks junior
to, or on a parity with, the Convertible Preferred Stock in respect
of the payment of dividends and distributions upon liquidation,
dissolution or winding up of the Corporation; or (b) the
authorization, issuance or increase in the amount of any notes,
commercial paper, bonds, mortgages, debentures or other obligations
of the Corporation.

          8.   Ranking.  Any class or classes of stock of the
Corporation shall be deemed to rank:

                               -27-
<PAGE>

          (i)  prior to the Convertible Preferred Stock, as to
dividends or as to distribution of assets upon liquidation,
dissolution or winding up, if the holders of such class shall be
entitled to the receipt of dividends or of amounts distributable
upon liquidation, dissolution or winding up, as the case may be, in
preference or priority to the holders of Convertible Preferred
Stock.

          (ii)  on a parity with the Convertible Preferred Stock,
as to dividends or as to distribution of assets upon liquidation,
dissolution or winding up, whether or not the dividend rates,
dividend payment dates or redemption or liquidation prices per
share thereof are different from those of the Convertible Preferred
Stock, if the holders of such class of stock and the Convertible
Preferred Stock shall be entitled to the receipt of dividends or of
amounts distributable upon liquidation, dissolution or winding up,
as the case may be, in proportion to their respective amounts of
accrued and unpaid dividends per share or liquidation prices,
without preference or priority one over the other, and 

          (iii)  junior to the Convertible Preferred Stock, as to
dividends or as to the distribution of assets upon liquidation,
dissolution or winding up, if such stock shall be Common Stock or
Series A Junior Participating Cumulative Preferred Stock or any
other class or series of capital stock of the Corporation if the
holders of Convertible Preferred Stock shall be entitled to receipt
of dividends or of amounts distributable upon liquidation,
dissolution or winding up, as the case may be, in preference or
priority to the holders of shares of such stock.

          9.   Outstanding Shares.  For purposes of this
Certificate of the Designations, Powers, Preferences and Rights,
all shares of Convertible Preferred Stock issued by the Corporation
shall be deemed outstanding except (i) from the date fixed for
redemption pursuant to Section 6 hereof, all shares of Convertible
Preferred Stock that have been so called for redemption under
Section 6, to the extent provided thereunder, (ii) from the date of
surrender of a certificate evidencing shares of Convertible
Preferred Stock, all shares of Convertible Preferred Stock
represented by such certificate and converted into Common Stock;
and (iii) from the date of registration of transfer, all shares of
Convertible Preferred Stock held of record by the Corporation or
any majority-owned subsidiary of the Corporation.

          10.  Status of Acquired Shares.  Shares of Convertible
Preferred Stock redeemed by the Corporation, received upon
conversion pursuant to Section 6 or otherwise acquired by the
Corporation will be restored to the status of authorized but
unissued shares of Preferred Stock, without designation as to
class, and may thereafter be issued, but not as shares of
Convertible Preferred Stock.

          11.  Preemptive Rights.  The Convertible Preferred Stock
is not entitled to any preemptive or subscription rights in respect
of any securities of the Corporation.

          12.  Severability of Provisions.  Whenever possible, each
provision hereof shall be interpreted in a manner as to be
effective and valid under applicable law, but if any provision
hereof is held to be prohibited by or invalid under applicable law,
such provision shall be ineffective only to the extent of such
prohibition or invalidity, without invalidating or otherwise
adversely affecting the remaining provisions hereof.  If a court of
competent jurisdiction should determine that a provision hereof
would be valid or enforceable if a period of time were extended or
shortened or a particular percentage were increased or decreased,
then such court may make such change as shall be necessary to
render the provision in question effective and valid under
applicable law.

Certificate to be made under the seal of the Corporation and signed
