                         ARTICLES OF AMENDMENT TO THE
                       RESTATED ARTICLES OF INCORPORATION
                                       OF
                                EEX CORPORATION

Amendment to its Restated Articles of Incorporation:

     FIRST:  The name of the corporation is EEX Corporation.

corporation is hereby deleted and replaced in its entirety with the following:

     "(A)  Authorized Capital Stock.

          (i) The aggregate number of shares of all classes of stock the Company
     shall have authority to issue is 160,000,000 consisting of and divided
     into:

          (a)  one class of 150,000,000 shares of Common Stock, par value $0.01
               per share (the "Common Stock"); and

          (b)  one class of 10,000,000 shares of Preferred Stock, no par value
               (the "Preferred Stock"), which may be divided into and issued in
               one or more series, as hereinafter provided.

          (ii) Reverse Stock Split.  Effective as of the close of business on
     the date of filing this amendment to the Restated Articles of Incorporation

     shares of Common Stock of the corporation issued and outstanding, shall be

     Common Stock of the corporation.  The number of authorized shares, the
     number of shares of treasury stock and the par value of the Common Stock
     shall not be affected by the Reverse Stock Split.  Each stock certificate
     that prior to the Effective Time represented shares of Common Stock shall,
     following the Effective Time, represent the number of shares into which the
     shares of Common Stock represented by such certificate shall be combined.
     Fractional shares that occur as a result of the foregoing shall be
     purchased by the corporation based upon the closing price reported for the
     Common Stock on the New York Stock Exchange on the date of filing this
     amendment."

     of the foregoing; and

     (j)  any other special rights and qualifications, limitations or
     restrictions permitted by the TBCA to be granted to or imposed on the

     Any of the designations, preferences, limitations and relative rights of
the shares of any series so established may be made dependent upon facts
ascertainable outside the Articles of Incorporation, which facts may include
future acts of the Company, provided that the manner in which such facts shall
operate upon the designations, preferences, limitations and relative rights of
the shares of any series shall be set forth in the resolution or resolutions
establishing the series.

the series issued on different dates will cumulate, if cumulative. The Board of

within each series of Preferred Stock; provided, that the Board of Directors may
not decrease the number of shares within a series to less than the number of
shares within such series that are then outstanding.

shareholder's holding shares of any class or series have any preemptive or
preferential right to purchase or subscribe to any shares of any class or series
of the Company, now or hereafter to be authorized, or any notes, debentures,
bonds or other securities convertible into or carrying options or warrants to
purchase shares of any class or series, now or hereafter to be authorized,
whether or not the issuance of any such shares, or such notes, debentures, bonds
or other securities, would adversely affect the dividend or voting rights of
such shareholders, other than such rights, if any, as the Board of Directors in
its discretion may fix; and the Board of Directors may issue shares of any class
or series of the Company, or any notes, debentures, bonds or other securities
convertible into or carrying options or warrants to purchase shares of any class
or series, without offering any such shares of any class or series, either in
whole or in part, to the existing shareholders of any class or series.

(D)  Subordination of Common Stock.  The Common Stock shall be subject and
subordinate to the rights, privileges and preferences of any series of Preferred
Stock to the extent set forth in the resolution or resolutions of the Board of
Directors establishing the series.
<PAGE>

(E)  Other Provisions Applicable to Capital Stock.

     (a)  Each outstanding share of Common Stock shall be entitled to one vote
          on each matter submitted to a vote at a meeting of shareholders,
          except as otherwise provided by the TBCA or as set forth in the
          resolution or resolutions of the Board of Directors establishing any
          series of Preferred Stock.

     (b)  At each election for directors of the Company ("Directors"), every
          shareholder entitled to vote at such election shall have the right to
          vote the number of shares owned by such shareholder for as many
          persons as there are Directors to be elected and for whose election
          such shareholder has a right to vote; provided that cumulative voting
          in the election for Directors is prohibited.

     (c)  In the event of any dissolution, liquidation or winding up of the
          Company, but subject to the rights of the holders of any series of
          Preferred Stock, holders of Common Stock shall be entitled to receive
          pro rata all of the remaining assets of the Company available for
          distribution to its shareholders.

     (d)  Subject to the rights of the holders of Preferred Stock as set forth
          in the resolution or resolutions of the Board of Directors
          establishing any series of Preferred Stock, dividends may be paid upon
          Common Stock to the exclusion of Preferred Stock out of any assets of
          the Company available therefor.

_____________________________

     As adopted by the Board of Directors of the Company effective
September 11, 1996:

          "RESOLVED, that pursuant to the authority conferred upon the Board
     of Directors of this Company by the provisions of the Restated Articles of
     Incorporation of this Company, the Board of Directors hereby creates a new
     series of Preferred Stock of the Company which shall consist of 1,000,000
     shares of no par value, which shall be designated and known as $200 Series
     A Junior Participating Preferred Stock, and that in addition to the
     preferences, rights, voting powers and the restrictions or qualifications
     of all shares of Preferred Stock regardless of series, described and
     expressed in the Restated Articles of Incorporation of the Company, the
     Board of Directors hereby declares that the shares of the $200 Series A
     Junior Participating Preferred Stock shall have the terms, conditions,
     rights and preferences, as follows:

     1.  Designation.  The shares of such series shall be designated "$200
Series A Junior Participating Preferred Stock" (herein called "Series A
Preferred Stock").

     2.  Number.  The number of shares of Series A Preferred Stock shall be
1,000,000, which number may be increased or decreased by resolution adopted by
the Board of Directors:
<PAGE>

provided, however, that no decrease shall reduce the number of authorized shares
of Series A Preferred Stock to less than the number of shares then issued and
outstanding plus the number of shares issuable upon the exercise of outstanding
rights, options for warrants or upon conversion of outstanding securities issued
by the Company.

     3.  Dividends.  Subject to the rights of the holders of any shares of any
other series of Preferred Stock (or any similar stock) of the Company with
respect to dividends, but in preference to the holders of shares of the Common
Stock, par value $0.01 per share (the "Common Stock"), the Company or of any
other class or series of stock of the Company ranking junior to the Series A
Preferred Stock, the holders of shares of Series A Preferred Stock shall be
entitled to receive, when, as and if declared by the Board of Directors out of
funds legally available for the purpose, dividends for each Quarterly Dividend
Period (as hereinafter defined) equal (rounded to the nearest cent) to the
greater of (a) $20 or (b) subject to the provision for adjustment hereinafter
set forth, 200 times the aggregate per share amount of all cash dividends, and
200 times the aggregate per share amount (payable in cash, based upon the fair
market value at the time the non-cash dividend or other distribution is declared
as determined in good faith by the Board of Directors) 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 (but not withdrawn) on the Common Stock during the
immediately preceding Quarterly Dividend Period, or, with respect to the first
Quarterly Dividend Period, since the first issuance of any share or fraction of
a share of Series A Preferred Stock.  In the event the Company shall at any time
after September 10, 1996 (the "Rights Declaration Date") (i) declare any
dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the
outstanding Common Stock, or (iii) combine the outstanding Common Stock into a
smaller number of shares, then in each such case the amount to which holders of
shares of Series A Preferred Stock were entitled immediately prior to such event
under clause (b) of the preceding sentence shall be adjusted by multiplying such
amount by a fraction the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

     As used herein "Quarterly Dividend Period" shall mean a period of three
months which shall commence on February 1, May 1, August 1 and November 1 in
each year (or in the case of original issuance, from the date of original
issuance) and shall end on and include the day next preceding the first date of
the next Quarterly Dividend Period. The first day of each such Quarterly
Dividend Period shall be the dividend payment date for the regular quarterly
dividend payable for the preceding Quarterly Dividend Period, except that the
first dividend on shares of Series A Preferred Stock shall be payable on the
quarterly payment date next succeeding the expiration of 30 days after the date
of initial issue of any shares of the Series A Preferred Stock.

     Dividends on the Series A Preferred Stock, if any, shall be cumulative so
that no dividend (other than a dividend payable in Common Stock) or other
distribution shall be paid or declared or made on, and no amounts shall be
applied to the purchase or redemption of, the
<PAGE>

Common Stock or any other class of stock ranking junior to the Series A
Preferred Stock as to dividends or assets unless (i) full cumulative dividends
for all past Quarterly Dividend Periods have been paid or declared and set apart
for payment, and full cumulative dividends for then current Quarterly Dividend
Period shall have been or simultaneously therewith shall be paid and declared on
outstanding Series A Preferred Stock, and (ii) after giving effect to such
payment of dividend, other distribution, purchase or redemption, the aggregate
capital of the Company applicable to all capital stock outstanding ranking
junior to the Series A Preferred Stock as the dividends or assets plus the
consolidated surplus of the Company and its subsidiaries shall exceed the
aggregate amount payable on involuntary dissolution, liquidation or winding up
of the Company on all shares of the Series A Preferred Stock and all stock
ranking prior to on a parity with the Series A Preferred Stock as the dividends
or assets to be outstanding after the payment of such dividend, other
distribution, purchase or redemption. Determinations made with respect to the
declaration and payment of dividends and other distributions shall be made in
accordance with the provisions of the Texas Business Corporation Act, as amended
and in effect at the time (the "TBCA").

     4.  Liquidation.  In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Company, the holders of the Series A Preferred
Stock shall, subject to the prior and superior rights of the holders of any
shares of any other series of Preferred Stock (or any similar stock) of the
Company, be entitled to receive the greater of (a) $200 per share, or (b) an
amount per share, subject to the provision for adjustment hereinafter set forth,
equal to 200 times the aggregate amount to be distributed per share to holders
of Common Stock, plus in either instance accrued dividends to the date of
distribution, whether or not earned or declared.  In the event the Company shall
at any time after the Rights Declaration Date (i) declare any dividend on Common
Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common
Stock, or (iii) combine the outstanding Common Stock into a smaller number of
shares, then in each such case the amount to which holders of shares of Series A
Preferred Stock were entitled immediately prior to such event pursuant to clause
(b) of the preceding sentence shall be adjusted by multiplying such amount by a
fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

     No distribution shall be made to the holders of shares of Common Stock or
any other stock ranking junior to the Series A Preferred Stock upon liquidation,
distribution or winding up, unless, prior thereto, the holders of Shares of
Series A Preferred Stock shall have received the amounts set forth above. If the
assets available for distribution to holders of shares of Series A Preferred
Stock shall not be sufficient to pay in full the amounts so determined to be
payable on all shares of the Series A Preferred Stock in the event of such
voluntary or involuntary dissolution, liquidation or winding up, as the case may
be, then assets available for payment shall be distributed ratably among the
holders of the Series A Preferred Stock of all series in accordance with the
amounts so determined to be payable on the shares of each series in the event of
voluntary or involuntary dissolution, liquidation or winding up, as the case may
be, in proportion to the full preferential amounts to which they are
respectively entitled. After
<PAGE>

payment to the holders of the Series A Preferred Stock of the full preferential
amounts hereinbefore provided for, the holders of Series A Preferred Stock will
have no other rights or claims to any of the remaining assets of the Company
either upon distribution of such assets or upon dissolution, liquidation or
winding up. The sale of all or substantially all of the property of the Company
to, or the merger or consolidation of the Company into or with, any other
corporation, or the purchase or redemption by the Company of any shares of its
Preferred Stock, or its Series A Preferred Stock or its Common Stock or any
other class of its stock shall not be deemed to be a distribution of assets or a
dissolution, liquidation or winding up for the purpose of this paragraph.

     5.  Optional Redemption.  So long as full cumulative dividends on all
outstanding shares of Series A Preferred Stock for all dividend periods ending
on or prior to the date fixed for redemption shall have been paid or declared
and set apart for payment and  subject to any applicable requirements of Texas
law and the rights of the holders of any shares of any other series of Preferred
Stock (or any similar stock) of the Company, the Company shall have the option
to redeem the whole or any part of the Series A Preferred Stock at any time on
at least 30 days notice in accordance with the provisions of the procedures for
redemptions set forth in the TBCA at a redemption price equal to the greater of
(a) $200 and (b), subject to the provision for adjustment hereinafter set forth,
200 times the "current per share market price" of the Common Stock on the date
of mailing of the notice of redemption, together with unpaid accumulated
dividends to the date of such redemption.  In the event the Company shall at any
time after the Rights Declaration Date (i) declare any dividend on Common Stock
payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock
or (iii) combine the outstanding Common Stock into a smaller number of shares,
then in each such case the amount to which holders of shares of Series A
Preferred Stock were otherwise entitled immediately prior to such event under
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.  The "current per share market price" on any date shall be deemed to be
the average of the closing price per share of such Common Stock for the 10
consecutive "trading days" (as such term is hereinafter defined) immediately
prior to such date.  The closing price for each day shall be the last sale
price, regular way, or, in case no such sale takes place on such day, the
average of the closing bid and asked prices, regular way, in either case as
reported in the principal consolidated transaction reporting system with respect
to securities listed or admitted to trading on the New York Stock Exchange or,
if the Common Stock is not listed or admitted to trading on the New York Stock
Exchange, as reported in the principal consolidated transaction reporting system
with respect to securities listed or admitted to trading on the principal
national securities exchange on which the Common Stock is listed or admitted to
trading or, if the Common Stock is not listed or admitted to trading on any
national securities exchange, the last  quoted price or, if not so quoted the
average of the high bid and low asked prices in the over-the-counter market, as
reported by the National Association of Securities Dealers, Inc. Automated
Quotations System ("NASDAQ") or such other system then in use or, if on any such
date the Common Stock is not quoted by any such organization, the average of the
closing bid and
<PAGE>

asked prices as furnished by a professional market maker making a market in the
Common Stock selected by the Board of Directors of the Company. If on such date
no such market maker is making a market in the Common Stock, the fair value of
the Common Stock on such date as determined in good faith by the Board of
Directors of the Company shall be used. The term "trading day" shall mean a day
on which the principal national securities exchange on which the Common Stock is
listed or admitted to trading is open for transaction of business or, if the
Common Stock is not listed or admitted to trading on any national securities
exchange, a Monday, Tuesday, Wednesday, Thursday or Friday on which banking
institutions in the State of New York are not authorized or obligated by law or
executive order to close.

     6.  Treasury Shares.  So long as any shares of the Series A Preferred Stock
are outstanding, shares of the Series A Preferred Stock which are purchased,
redeemed or otherwise acquired by the Company shall not be reissued, or
otherwise disposed of, as shares of Series A Preferred Stock.

     7.  Conversion.  Other than as set forth above, the Series A Preferred
Stock shall not have any conversion or exchange rights.

     8.  Voting Rights.

     (A)  Each share of Series A Preferred Stock shall entitle the holder
thereof to 200 votes on all matters submitted to a vote of the shareholders of
the Company. In the event the Company shall at any time after the Rights
Declaration Date, (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such as
the number of votes 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)  The Series A Preferred Stock shall have no voting rights other than
the voting rights set forth herein, in the Restated Articles of Incorporation of
the Company or as otherwise provided by Texas law.

     9.  Consolidation, Merger, etc.  In case the Company shall enter into any
consolidation, merger, combination or other transaction in which the shares of
Common Stock are exchanged for or converted or changed into other stock or
securities, cash and/or other property, then in any such case proper provision
shall be made so that each share of Series A Preferred Stock shall at the same
time be similarly exchanged for or converted or changed into an amount per
share, subject to the provision for adjustment hereinafter set forth, equal to
200 times the aggregate amount of stock, securities, cash and/or any other
property (payable in kind), as the case may be, for which or into which each
share of Common Stock is exchanged for or converted or changed.  In the event
the Company shall at any time after the Rights
