                                     STOCK.


     SECTION 1.  Each holder of fully paid stock shall be entitled to a
certificate or certificates of stock stating the number and class of shares, and
the designation of the series, if any, which such certificate represents.  All
certificates of stock shall at the time of their issuance be signed either
manually or by facsimile signature by the Chairman, the President or a Vice
President and by the Secretary or an Assistant Secretary.  All certificates of
stock shall be sealed with the seal of the Company or a facsimile of such seal,
shall be countersigned either manually or by facsimile signature by a Transfer
Agent and shall be authenticated by manual signature and registered by a
Registrar.  The Board of Directors shall appoint one or more Transfer Agents,
none of whom shall be officers of the Company authorized to sign certificates of
stock, and one or more Registrars, each of which Registrars shall be a bank or
trust company.  Certificates of stock shall not be valid until countersigned by
a Transfer Agent and authenticated and registered by a Registrar in the manner
provided by the Board of Directors.

     SECTION 2.  Shares of stock shall be transferable only on the books of the
Company and, except as hereinafter provided or as otherwise required by law,
shall be transferred only upon proper endorsement and surrender of the
certificates issued therefor.  If an outstanding certificate of stock shall be
lost, destroyed or stolen, the holder thereof may have a new certificate upon
producing evidence satisfactory to the Board of Directors of such loss,
destruction or theft, and upon furnishing to the Company, the Transfer Agents
and the Registrars a bond of indemnity deemed sufficient by the Board of
Directors against claims under the outstanding certificate.

     SECTION 3.  The certificates for each class or series of stock shall be
numbered and issued in consecutive order and a record shall be kept of the name
and address of the person to whom each certificate is issued, the number of
shares represented by the certificate and the number and date of the
certificate.  All certificates exchanged or returned to the Company or the
Transfer Agent for transfer shall be canceled and filed.

                                      -1-

 
     SECTION 4.  For the purpose of determining shareholders entitled to notice
of or to vote at any meeting of shareholders, or shareholders entitled to
receive payment of any dividend, or in order to make a determination of
shareholders for any other proper purpose, the Board of Directors may fix in
advance a date as the record date for any such determination of shareholders,
such date in any case to be not more than sixty days and, for a meeting of
shareholders, not less than ten days, or in the case of a merger, consolidation,
share exchange, dissolution or sale, lease or exchange of assets, not less than
twenty days, immediately preceding such meeting.

     SECTION 5.  If any subscription for stock in the Company or any installment
of such subscription shall be unpaid when due, as the Board of Directors shall
have determined the time for payment, and shall continue unpaid for twenty days
after demand for the amount due, made either in person or by written notice duly
mailed to the last address, as it appears on the records of the Company, of the
subscriber or other person by whom the subscription or installment shall be
payable, the stock or subscription upon which payment shall be so due shall,
upon the expiration of said twenty days, become and be forfeited to the Company
without further action, demand or notice, and such stock or subscription may be
sold at public sale, subject to payment of the amount due and unpaid, plus all
costs and expenses incurred by the Company in that connection, at a time and
place to be stated in a written notice to be mailed to the recorded address of
the delinquent subscriber or other person in default on the subscription at
least ten days prior to the time fixed for such sale; provided, that the excess
of proceeds of such sale realized over the amount due and unpaid on said stock
or subscription shall be paid to the delinquent subscriber of other person in
default on the subscription, or to his or her legal representative; and,
provided further, that no forfeiture of stock, or of any amounts paid upon a
subscription therefor, shall be declared as against the estate of any decedent
before distribution shall have been made of the estate.

     The foregoing provisions for the forfeiture and sale of  stock or
subscriptions shall not exclude any other remedy which may lawfully be
enforceable at any time, by forfeiture of stock or of amounts theretofore paid
or otherwise, against any person for nonpayment of a subscription or of any
installment thereof.

     SECTION 6.  Transfers of shares shall be made only on the books of the
Company by the registered holder thereof or by his or her legal representative,
who shall furnish proper evidence of authority to transfer, or by his or her
attorney or successor thereunto authorized by power of attorney or by documents
duly executed and filed with the Secretary or Transfer Agent of the Company, and
upon surrender for cancellation of the certificate for such shares.  The person
in whose name shares stand on the

                                      -2-

 
books of the Company shall be deemed the owner thereof for all purposes as
regards the Company.

     SECTION 7.  The Company shall be entitled to treat the holder of record of
any share or shares of stock as the holder in fact thereof and accordingly,
shall not be bound to recognize any equitable or other claim to or interest in
such share or shares on the part of any other person, whether or not it shall
have express or other notice thereof, except as otherwise provided by the laws
of the State of Illinois.


                                  ARTICLE II.

                           MEETINGS OF SHAREHOLDERS.

     SECTION 1.  The regular annual meeting of the shareholders of the Company
for the election of Directors and for the transaction of such other business as
may come before the meeting shall be held on such day in April or May of each
year as the Board of Directors may by resolution determine.  Each such regular
annual meeting and each special meeting of the shareholders shall be held at
such place as may be fixed by the Board of Directors and at such hour as the
Board of Directors shall order.

     SECTION 2.  Special meetings of the shareholders may be called by the
Chairman, by the Board of Directors, by a majority of the Directors individually
or by the holders of not less than one-fifth of the total outstanding shares of
capital stock of the Company.

     SECTION 3.  Written notice stating the place, day and hour of the meeting
of the shareholders and, in the case of a special meeting, the purpose or
purposes for which the meeting is called shall be delivered not less than ten
nor more than sixty days before the date of the meeting, or in the case of a
merger, consolidation, share exchange, dissolution or sale, lease or exchange of
assets not less than twenty nor more than sixty days before the date of the
meeting, either personally or by mail, by or at the direction of the Chairman,
the Secretary or the persons calling the meeting, to each shareholder of record
entitled to vote at such meeting.  If mailed, such notice shall be deemed to be
delivered when deposited in the United States mail addressed to the shareholder
at the shareholder's address as it appears upon the records of the Company, with
postage thereon prepaid.

     SECTION 4.  At all meetings of the shareholders, a majority of the
outstanding shares of stock, entitled to vote on a matter, represented in person
or by proxy, shall constitute a quorum for consideration of such matter, but the
shareholders represented at any meeting, though less than a quorum, may adjourn
the meeting to some other day or sine die.  If a quorum is present, the

                                      -3-

 
affirmative vote of the majority of the shares of stock represented at the
meeting and entitled to vote on a matter shall be the act of the shareholders,
unless the vote of a greater number or voting by classes is required by law or
the articles of incorporation.

     SECTION 5.  At every meeting of the shareholders, each outstanding share of
stock shall be entitled to one vote on each matter submitted for a vote.  In all
elections for Directors, every shareholder 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, or to cumulate such votes and give one candidate as
many votes as shall equal the number of Directors to be elected multiplied by
the number of such shares or to distribute such cumulative votes in any
proportion among any number of candidates.  A shareholder may vote either in
person or by proxy.  A shareholder may appoint a proxy to vote or otherwise act
for him or her by signing an appointment form and delivering it to the person so
appointed.

     SECTION 6.  Any meeting at which a quorum of shareholders is present, in
person or by proxy, may adjourn from time to time without notice, other than
announcement at such meeting, until its business is completed.  At the adjourned
meeting, the Company may transact any business which might have been transacted
at the original meeting.  If the adjournment is for more than thirty days, a
notice of the adjourned meeting shall be given to each shareholder of record
entitled to vote at the meeting.

     SECTION 7.  The Secretary of the Company shall make or cause to be made,
within twenty days after the record date for a meeting of shareholders of the
Company or ten days before such meeting, whichever is earlier, a complete list
of the shareholders entitled to vote at such meeting, arranged in alphabetical
order, with the address of and the number of shares held by each, which list,
for at least ten days prior to such meeting, shall be kept on file at the
registered office of the Company and shall be subject to inspection by any
shareholder, and to copying at such shareholder's expense, at any time during
usual business hours.  Such list shall also be produced and kept open at the
time and place of the meeting and shall be subject to the inspection of any
shareholder during the whole time of the meeting.

     SECTION 8.  The Chairman and the Secretary of the Company shall, when
present, act as chairman and secretary, respectively, of each meeting of the
shareholders.

     SECTION 9.  At any meeting of shareholders, the chairman of the meeting
may, or upon the request of any shareholder shall, appoint one or more persons
as inspectors for such meeting, unless an inspector or inspectors shall have
been previously appointed for such meeting by the Chairman.  Such inspectors

                                      -4-

 
shall ascertain and report the number of shares of stock represented at the
meeting, based upon their determination of the validity and effect of proxies,
count all votes and report the results and do such other acts as are proper to
conduct the election and voting with impartiality and fairness to all the
shareholders.

     SECTION 10.  Voting on any question or in any election may be viva voce
unless the presiding officer shall order or any shareholder shall demand that
voting be by ballot.


                                  ARTICLE III.

                              BOARD OF DIRECTORS.

     SECTION 1.  The business and affairs of the Company shall be managed by or
under the direction of the Board of Directors.  The number of Directors of the
Company shall be not less than ten nor more than fifteen.  The Directors shall
be elected at each annual meeting of the shareholders, but if for any reason the
election shall not be held at an annual meeting, it may be subsequently held at
any special meeting of the shareholders called for that purpose after proper
notice.  The Directors so elected shall hold office until the next annual
meeting and until their respective successors, willing to serve, shall have been
elected and qualified.  Directors need not be residents of the State of Illinois
or shareholders of the Company.  No person shall be eligible for nomination or
renomination as a Director by the management of the Company who, prior to the
date of election, shall have attained age seventy-two.  No person who is an
employe or a former employe of the Company or of a subsidiary of the Company
shall be eligible for nomination or renomination as a Director by the management
of the Company for a term commencing after such person ceases to be such an
employe; provided, however, that any Director of the Company who was a Director
of Commonwealth Edison Company, an Illinois corporation, in office on June 15,
1989 who is or has been such an employe may be renominated as a Director unless
such person shall have attained age sixty-five on or before the date of election
of Directors.

     SECTION 2.  Any vacancy occurring in the Board of Directors, including a
vacancy created by an increase in the number of directors, may be filled by
election at an annual meeting or at a special meeting of shareholders called for
that purpose; provided, however, that any vacancy in the Board of Directors
arising between meetings of shareholders by reason of an increase in the number
of directors or otherwise may be filled by the vote of a majority of the
directors then in office, although less than a quorum.  Any directors so elected
shall serve until the next annual meeting of shareholders.

                                      -5-

 
     SECTION 3.  A meeting of the Board of Directors shall be held immediately,
or as soon as practicable, after the annual election of Directors in each year,
provided a quorum for such meeting can be obtained.  Notice of every meeting of
the Board, stating the time and place at which such meeting will be held, shall
be given to each Director personally, by telephone or by other means of
communication at least one day, or by depositing the same in the mails properly
addressed at least two days before the day of such meeting.  A meeting of the
Board of Directors may be called at any time by the Chairman or by any two
Directors and shall be held at such place as shall be specified in the notice
for such meeting.

     SECTION 4.  A majority of the number of Directors then in office, but not
less than six, shall constitute a quorum for the transaction of business at any
meeting of the Board, but a lesser number may adjourn the meeting from time to
time until a quorum is obtained, or may adjourn sine die.  The act of the
majority of the Directors present at a meeting at which a quorum is present
shall be the act of the Board of Directors.

     SECTION 5.  Each member of the Board not receiving a salary from the
Company or a subsidiary of the Company shall be paid such fees as the Board of
Directors may from time to time, by resolution adopted by the affirmative vote
of a majority of the Directors then in office, and irrespective of any personal
interest of any of its members, determine.  The Directors shall be paid their
reasonable expenses, if any, of attendance at each meeting of the Board of
Directors.  Members of any committee of the Board of Directors may be allowed
like fees and expenses for service on or attendance at meetings of such
committee.  No such payment shall preclude any Director from serving the Company
in any other capacity and receiving compensation therefor.

     SECTION 6.  A Director of the Company who is present at a meeting of the
Board of Directors at which action is taken on any corporate matter shall be
conclusively presumed to have assented to the action taken unless his or her
dissent shall be entered in the minutes of the meeting or unless he shall file
his or her written dissent to such action with the person acting as Secretary of
the meeting before the adjournment thereof or shall forward such dissent by
registered mail to the Secretary of the Company immediately after the
adjournment of the meeting.  Such right to dissent shall not apply to a director
who voted in favor of such action.

                                      -6-

                                   ARTICLE V.

                                   OFFICERS.


     SECTION 1.  There shall be elected by the Board of Directors, at its
first meeting after the annual election of Directors in each year if
practicable, the following principal officers of the Company, namely: a
Chairman, a President, such number of Executive Vice Presidents, Senior Vice
Presidents and Vice Presidents as the Board at the time may decide upon, a
Secretary, a Treasurer and a Comptroller; and the Board may also provide for a
Vice Chairman and such other officers, and prescribe for each of them such
duties, as in its judgment may from time to time be desirable to conduct the
affairs of the Company.  No officer shall be elected for a term extending beyond
the first day of the month following the month in which such officer attains the
age of 65 years, on which date such officer shall be retired.  The Chairman
shall be a Director of the Company; any other officer above named may, but need
not, be a Director of the Company.  Any two or more offices may be held by the
same person.  All officers shall hold their respective offices until the first
meeting of the Board of Directors after the next succeeding annual election of
Directors and until their successors, willing to serve, shall have been elected,
but any officer may be removed from office by the Board of Directors whenever in
its judgment the best interests of the Company will be served thereby.  Such
removal, however, shall be without prejudice to the contract rights, if any, of
the person so removed.  Election of an officer shall not of itself create
contract rights.

                                      -10-

 
     SECTION 2.  The Chairman shall be the chief executive officer of the

including the power to appoint and discharge any and all officers, agents and
employes of the Company not elected or appointed directly by the Board of
Directors.  The Chairman shall, when present, preside at all meetings of the
shareholders and of the Board of Directors.  The Chairman shall have authority
to call special meetings of the shareholders and meetings of the Board of
Directors, and of any committee of the Board of Directors and, when neither the
Board of Directors nor the Executive Committee is in session, to suspend the
authority of any other officer or officers of the Company, subject, however, to
the pleasure of the Board of Directors or of the Executive Committee at its next
meeting.  The Chairman, or such other officer as the Chairman may direct, shall
be responsible for all internal audit functions, and the internal audit
personnel shall report directly to the Chairman or to such other officer.

     SECTION 3. In the absence or disability of the Chairman, the powers and
duties of the Chairman shall be performed by the President or, in the
President's absence or disability, by such other principal officer as the Board
of Directors or the Executive Committee may designate.

     SECTION 4.  Except insofar as the Board of Directors, the Executive
Committee or the Chairman shall have devolved responsibilities on the other
principal officers, the President shall be responsible for the general

foregoing, the Company may enter into one or more agreements with any person
which provide for indemnification greater or different than that provided in
this Section 1(b). Any repeal or modification of this Section 1(b) shall not
adversely affect any right or protection existing hereunder immediately prior to
such repeal or modification.

proceeding theretofore or thereafter brought or threatened based in whole or in
part upon any such state of facts.

     SECTION 3. The indemnification provided or permitted by this Article shall
not be deemed exclusive of any other rights to which those indemnified may be

status as such, whether or not the Company would have the power to indemnify
such person against such liability under the laws of the State of Illinois.
