                                 OF CILCORP Inc.


                                  ARTICLE EIGHT

         The holders of capital stock of the corporation now or hereafter
outstanding shall not have the right to cumulate their respective votes in any
election for directors of the corporation.

                                  ARTICLE NINE

Paragraph 1: A Business Combination (as hereinafter defined) shall require the
affirmative vote of the holders of that percentage of the Voting Shares (as
hereinafter defined) which is the greater of:

     A. 75%, or

     B. the percentage calculated by dividing (x) the sum of (i) the aggregate
number of Voting Shares which are beneficially owned by each and every Related
Person (as hereinafter defined) and (ii) one-half of all Voting Shares which are
not beneficially owned by any such Related Person by (y) the total number of
Voting Shares (the "Required Percentage"); provided, however, that for the
purpose of determining the Required Percentage of affirmative votes required for
any Business Combination between the corporation or any Subsidiary (as
hereinafter defined) and any Related Person, only the Related Person which is a
party to such transaction shall be deemed a "Related Person" under this
Paragraph 1.

Such affirmative vote shall be required notwithstanding the fact that no vote
may be required, or that some lesser percentage may be specified, by law or
otherwise.

Paragraph 2: The provisions of Paragraph 1 shall not apply to a Business
Combination, and such Business Combination shall require the affirmative vote of
the holders of a majority of the Voting Shares, if all of the following
conditions shall have been satisfied:

                                       1




     A. If, with respect to such Business Combination (i) at least two-thirds of
the Continuing Directors (as hereinafter defined) shall have approved expressly
a memorandum of understanding with the Related Person which is a party to such
transaction, consistent in material terms with the Business Combination for
which a shareholder vote is sought, before such Related Person became a Related
Person; or (ii) at least two-thirds of the Continuing Directors shall have
approved expressly in advance the acquisition of the Voting Shares that caused
such Related Person to become a Related Person; or (iii) such Business
Combination is approved expressly by the affirmative vote of at least two-thirds
of the Continuing Directors before the consummation of such transaction.

     B. The aggregate amount of cash or fair market value of Other Consideration
(as hereinafter defined) to be received per share by holders of Voting Shares in
such Business Combination is not less than the Highest Per Share Price (as
hereinafter defined) paid by the Related Person in acquiring within the two-year
period immediately preceding the Business Combination any shares of capital
stock of the corporation which if continued to be held at the Record Date (as
hereinafter defined) would be (or are) Voting Shares.

     C. The consideration to be received by Public Holders (as hereinafter
defined) in such Business Combination shall be in the same form and of the same
kind as the consideration paid by the Related Person in acquiring within the
two-year period immediately preceding the Business Combination any shares of
capital stock of the corporation which if continued to be held at the Record
Date would be (or are) Voting Shares.

     D. After such Related Person became a Related Person and before the
Business Combination the Related Person shall have taken steps to ensure that
the corporation's Board of Directors included at all times representation by
Continuing Directors proportionate to the ratio that the Voting Shares which
from time to time are owned by Public Holders bear to all Voting Shares
outstanding at such respective times (with a Continuing Director to occupy any
resulting fractional board position);

     E. Before the Business Combination, such Related Person shall not have (i)
received the benefit, directly or indirectly, (except proportionately as a
shareholder) of any loans, advances, guarantees, pledges, financial assistance
or tax credits provided by the corporation, or (ii) made any major change in the
corporation's business or equity capital structure without the approval of at
least two-thirds of the Continuing Directors.

                                       2





     F. A proxy statement responsive to the requirements of the Securities Act
of 1933, as amended, shall have been mailed to all holders of Voting Shares for
the purpose of soliciting shareholder approval of such Business Combination. The
proxy statement shall contain on the front page thereof, in a prominent place,
any recommendations as to the advisability (or inadvisability) of the Business
Combination which the Continuing Directors, or any of them, may have furnished
in writing and, if deemed advisable by a majority of the Continuing Directors,
an opinion of a reputable investment banking firm as to the fairness (or lack of
fairness) of the terms of such Business Combination from the point of view of
the Public Holders (such investment banking firm to be selected by a majority of
the Continuing Directors, to be furnished with all information it reasonably
requests and to be paid a reasonable fee for its services upon receipt by the
corporation of such opinion).

Paragraph 3: The following definitions shall apply to the provisions of Article
Nine and Paragraph 1 of Article Ten of these Articles of Incorporation.

     A. "Affiliate" and "Associate" shall have the respective meanings given

     60 days) pursuant to any agreement, arrangement or understanding or upon
     the exercise of conversion rights, exchange rights, warrants, options, or
     otherwise, or (b) the right to vote pursuant to any agreement, arrangement
     or understanding; or

     similar transaction (whether or not with or into or otherwise involving a
     Related Person) which has the effect, directly or indirectly, of increasing
     the proportionate share of the outstanding shares of any class of capital
     stock of the corporation or any Subsidiary which is directly or indirectly
     owned by any Related Person; or

        (vi) any agreement, contract or other arrangement providing for any of
     the transactions described in (i) through (v) of this subparagraph C.

         I, M.J. Murray, Secretary of CILCORP Inc., hereby certify that at the
Annual Meeting of Shareholders of the Company held April 28, 1987, at which a

except matters required to be voted on exclusively by holders of preferred stock
or of any series of preferred stock. Subject only to the prior rights and
preferences of the preferred stock, the holders of the common stock shall be
entitled to dividends thereon, when, as and if declared by the Board of
Directors out of funds of the Company legally available therefor. In the event
of any dissolution or liquidation of the Company, the holders of the common

holders of the preferred stock have been satisfied, all of the assets of the
Company remaining available for distribution, if any.

Preferred Stock. The preferred stock may be issued from time to time in one or
more series and shall have preference over the common stock as to the payment of
dividends and to the assets of the Company upon the voluntary or involuntary
liquidation of the Company. Dividends on the preferred stock shall be cumulative
and shares of preferred stock shall have such rights of conversion into shares
of any other class, or into shares of any series of the same or any other class,
as shall be provided with respect to such shares. The Board of Directors by
resolution shall establish each series of preferred stock and fix and determine
the number of shares and the relative rights and preferences of each such
series, provided that




all shares of the preferred stock shall be identical except as to the following
relative rights and preferences, as to which there may be variations fixed and
determined by the Board of Directors between different series:

         (1)      The rate of dividend.
         (2)      The price at and the terms and conditions on which shares....
         (3)      The amount payable upon shares in event of involuntary
                  liquidation.
         (4)      The amount payable upon shares in event of voluntary
                  liquidation.
         (5)      Sinking fund provisions for the redemption or purchase of
                  shares.
         (6)      The terms and conditions on which shares may be converted, if
                  the shares of any series are issued with the privilege of
                  conversion.
         (7)      The limitation or denial of voting rights, or the grant of
                  special voting rights.
         (8)      Any other rights or preferences now or hereafter permitted by
                  the laws of the State of Illinois as variations between
                  different series of preferred stock.

         RESOLVED FURTHER: That Article Ten of the Article of Incorporation of
this Company, be amended to read in its entirety as follows:

         Paragraph 1: Any amendment, alteration, change or repeal of Article
Nine or this Paragraph 1 of Article Ten of these Articles of Incorporation shall
require the affirmative vote of the holders of at least 75% of the Voting Shares

this Paragraph 1 of Article Ten shall not apply to, and the majority vote
prescribed by Paragraph 2 of this Article Ten shall be required for, any
amendment, alteration, change or repeal recommended to the shareholders by
two-thirds or more of the Continuing Directors.

         Paragraph 2: Any provision of these Articles of Incorporation other
than Article Nine and Paragraph 1 of Article Ten may be amended, altered,
changed or repealed by the affirmative vote of the holders of a majority of the
outstanding capital stock of the corporation having the right to vote on the
issue and, if a class vote thereon is required pursuant to applicable law, by
the affirmative vote of the holders of a majority of the outstanding shares of
each such class, and

                                   ARTICLE SIX

         The number of directors of the corporation shall be such number as may
         from time to time be fixed by or pursuant to the By-laws. The directors
         shall be elected and divided into three classes, Class I, Class II and
         Class III, each class to be as nearly equal in number as possible. The
         directors shall initially be allocated to the same classes as those to
         which they were designated under the By-laws in effect immediately
         prior to the annual meeting in 1991. At each annual meeting the number
         of directors of the class whose terms expire at the time of such
         meeting (unless the number of directors in such class is increased or
         decreased as a result of a change in the total number of directors, in
         which case the number of directors in such class as so increased or
         deceased) shall be elected to hold office until the third succeeding
         annual meeting. Directors may be removed only for cause.

         RESOLVED: That Article Seven of the Articles of Incorporation of the
Company be amended to read in its entirety as follows:

                                  ARTICLE SEVEN

         In furtherance of, and not in limitation of, the powers conferred by
         statute, the Board of Directors of the corporation is expressly
         authorized and empowered to adopt, amend or repeal the By-laws (or any
         portion thereof) of the corporation. The shareholders of the
         corporation are authorized and empowered to adopt, amend or repeal the
         By-laws only by an affirmative vote of 75% of the voting power of the
         shares outstanding and entitled to vote thereon.

         RESOLVED: That Article Eight of the Articles of Incorporation of the
Company be amended to read in its entirety as follows:




                                  ARTICLE EIGHT

         Paragraph 1: The holders of capital stock of the corporation now or
hereafter outstanding shall not have the right to cumulate their respective
votes in any election for directors of the corporation.

         Paragraph 2: Any action required or permitted to be taken by the
shareholders of the corporation shall be taken only at a duly called annual or
special meeting. Such action may not be taken by written consent of the
shareholders.
