                                    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.

                                      -1-
<PAGE>

     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.

     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,

                                      -2-
<PAGE>

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 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.  (a) 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 properly come before the meeting shall be held on such day 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.

     (b)  Only such business shall be conducted at an annual meeting of
shareholders as shall have been properly brought before the meeting.  For
business to be properly brought

                                      -3-
<PAGE>

before the meeting, it must be:  (i) authorized by the Board of Directors and
specified in the notice, or a supplemental notice, of the meeting, (ii)
otherwise be brought before the meeting by or at the direction of the Board of
Directors or (iii) otherwise properly brought before the meeting by a
shareholder of the Company who is a shareholder of record at the time of giving
of the notice provided for in this Section, who shall be entitled to vote at
such annual meeting and who complies with the procedures set forth in this
Section 1(b).  For business to be properly brought before an annual meeting by a
shareholder, the shareholder must have given timely notice thereof in proper
written form to the Secretary of the Company.  To be timely, a shareholder's
notice must be delivered to or mailed and received at the principal executive
offices of the Company not less than 90 days nor more than 120 days prior to the
anniversary date of the immediately preceding annual meeting of shareholders;
provided, however, that in the event that the annual meeting is called for a
date that is not within 30 days before or after such anniversary date, notice by
the shareholder in order to be timely must be received not later than the close
of business on the 10th day following the day on which such notice of the date
of the annual meeting was mailed or, if earlier, the day on which public
announcement of the date of the annual meeting was made.  In no event shall the
public announcement of an adjournment or postponement of an annual meeting
commence a new time period for the giving of a shareholder's notice as described
above.  To be in proper written form, a shareholder's notice to the Secretary
shall set forth in writing as to each matter the shareholder proposes to bring
before the meeting (i) a brief description of such matter and the reasons for
conducting such business at the annual meeting, (ii) the name and address, as
they appear on the Company's books, of the shareholder proposing such business,
(iii) the number of shares of stock of the Company which are beneficially owned
by the shareholder, (iv) a description of all arrangements or understandings
between such shareholder and any other person(s) (including their names) in
connection with the proposal of such business by such shareholder and any
material interest of the shareholder in such business and (v) a representation
that such shareholder intends to appear in person or by proxy at the annual
meeting to bring such business before the meeting.  Notwithstanding anything in
the By-laws to the contrary, no business shall be conducted at an annual meeting
except in accordance with the procedures set forth in this Section 1(b).  The
chairman of an annual meeting at which any business is

                                      -4-
<PAGE>

proposed by a shareholder shall have sole authority to determine, if the facts
warrant, that such business was not properly brought before the meeting in
accordance with the provisions of this Section 1(b), and, if he should so
determine, he shall so declare to the meeting and any such business not properly
brought before the meeting shall not be transacted. For purposes of this Section
1(b), "public announcement" shall include disclosure in a press release issued
to one or more national financial or general news services or in a document
publicly filed by the Company with the Securities and Exchange Commission
pursuant to Section 13, 14 or 15(d) of the Securities Exchange Act of 1934, as
amended.

     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
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

                                      -5-
<PAGE>

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.

                                      -6-
<PAGE>

     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
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.

     Section 11. Only persons who are nominated in accordance with the
procedures set forth in this Section 11 shall be eligible for election at a
meeting of shareholders as directors of the Company.  Nominations of persons for
election to the Board of Directors of the Company may be made at a meeting of
shareholders (a) by or at the direction of the Board of Directors or a committee
of the Board of Directors or (b) by any shareholder of the Company who is a
shareholder of record at the time of giving of notice provided for in this
Section, who shall be entitled to vote for the election of directors at the
meeting and who complies with the procedures set forth in this Section 11.  Any
nomination by a shareholder shall be made pursuant to timely notice in writing
to the Secretary of the Company.  To be timely, a shareholder's notice shall be
delivered to or mailed and received at the principal executive offices of the
Company not less than 90 days nor more than 120 days prior to the anniversary
date of the immediately preceding annual meeting of shareholders; provided,
however, that in the event that the annual meeting is called for a date that is
not within 30 days before or after such anniversary date, notice by the
shareholder in order to be timely must be received not later than the close of
business on the 10th day following the day on which such notice of the date of
the annual meeting was mailed or, if earlier, the day on which public
announcement of the date of the annual meeting was made.  In no event shall the
public announcement of an adjournment or postponement of an annual meeting
commence a new time period for the giving of a shareholder's notice as described
above.  Such shareholder's

                                      -7-
<PAGE>

notice shall set forth (a) as to each person whom the shareholder proposes to
nominate for election or re-election as a director, all information relating to
such person that is required to be disclosed in solicitations of proxies for
election of directors, or is otherwise required, in each case pursuant to
Regulation 14A promulgated under the Securities Exchange Act of 1934, as amended
(including, without limitation, such person's written consent to being named in
the proxy statement as a nominee and to serving as a director if elected); and
(b) as to the shareholder giving the notice (i) the name and address, as they
appear on the Company's books, of such shareholder, (ii) the number of shares of
stock of the Company which are beneficially owned by such shareholder, (iii) a
description of all arrangements or understandings between such shareholder and
each proposed nominee and any other person(s) (including their names) pursuant
to which the nomination(s) are made by such shareholder, (iv) a representation
that such shareholder intends to appear in person or by proxy at the meeting to
nominate the persons named in such shareholder's notice and (v) any other
information relating to such shareholder that is or would be required to be
disclosed pursuant to Regulation 14A promulgated under the Securities Exchange
Act of 1934, as amended. At the request of the Board of Directors, any person
nominated by the Board of Directors for election as a director shall furnish to
the Secretary of the Company that information required to be set forth in a
shareholder's notice of nomination which pertains to the nominee. The chairman
of the meeting at which a shareholder nomination is presented shall have sole
authority to determine, if the facts warrant, that a nomination was not made in
accordance with the procedures prescribed by this Section 11, and if he should
so determine, he shall so declare to the meeting and the defective nomination
shall be disregarded. Notwithstanding the foregoing provisions of this Section
11, a shareholder shall also comply with all applicable requirements of the
Securities Exchange Act of 1934, as amended, and the rules and regulations
thereunder with respect to the matters set forth in this Section. For purposes
of this Section 11, "public announcement" shall include disclosure in a press
release issued to one or more national financial or general news services or in
a document publicly filed by the Company with the Securities and Exchange
Commission pursuant to Section 13, 14 or 15(d) of the Securities Exchange Act of
1934, as amended.

                              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 eight nor more than thirteen.  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 employee or a former employee 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 employee; 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 employee 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.

     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,

                                      -9-
<PAGE>

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.

     SECTION 7.  At the first meeting of the Board of Directors following the
annual meeting of shareholders each year, the Board shall elect a Lead Director.
The Lead Director shall be

                                      -10-
<PAGE>

elected from among the Outside Directors of the Company. For purposes hereof,
"Outside Directors" shall be those who are not and never have been employees of
the Company or any of its direct or indirect subsidiaries. The duties of the
Lead Director shall be to convene and chair meetings of the Outside Directors
and to assume other responsibilities which the Outside Directors might designate
from time to time. The Lead Director will consult with other Outside Directors
as to appropriate items for discussion at each such meeting.

                                  ARTICLE IV.

                     COMMITTEES OF THE BOARD OF DIRECTORS

     SECTION 1.  The Board of Directors may from time to time create committees,
standing or special, each committee to consist of two or more Directors of the
Company, and the Board shall appoint Directors to serve on such committees and
confer such powers upon such committees and revoke such powers and terminate the
existence of such committees, as the Board at its pleasure may determine,
subject to the limitations set forth in Section 8.40(c) of the Illinois Business
Corporation Act of 1983, as amended from time to time.

     SECTION 2.  Meetings of any committee of the Board may be called at any
time by the Chairman, by any two Directors or by the chairman of the committee
the meeting of which is being called and shall be held at such place as shall be
designated in the notice of such meeting.  Notice of each committee meeting
stating the time and place at which such meeting will be held shall be given to
each member of the committee personally, or by telecopy, or by depositing the
same in the mails properly addressed, at least one day before the day of such
meeting.  A majority of the members of a committee shall constitute a quorum
thereof but a lesser number may adjourn the meeting from time to time until a
quorum is obtained, or may adjourn sine die.  A majority vote of the members of
a committee present at a meeting at which a quorum is present shall be necessary
for committee action.

     SECTION 3.  The Board of Directors may from time to time designate from
among the Directors alternates to serve on one or more committees as occasion
may require.  Whenever a quorum cannot be secured for any meeting of any
committee from among the regular members thereof and designated alternates, the

                                      -11-
<PAGE>

member or members of such committee present at such meeting and not disqualified
from voting thereat, whether or not he or they constitute a quorum, may
unanimously appoint another member of the Board of Directors to act at the
meeting in place of such absent or disqualified member.

     SECTION 4.  Every Director of the Company, or member of any committee
designated by the Board of Directors pursuant to authority conferred by these
By-Laws, shall, in the performance of his or her duties, be fully protected in
relying in good faith upon the records of the Company and upon such information,
opinions, reports or statements presented to the Company by any of the Company's
officers or employees, or committees of the Board of Directors, or by any other
person as to matters the Director or member reasonably believes are within such
other person's professional or expert competence and who has been selected with
reasonable care by or on behalf of the Company.

     SECTION 5.  Unless otherwise limited by the Board of Directors and subject

                                  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.

     SECTION 2.  The Chairman shall be the chief executive officer of the
Company and shall have general authority over all the affairs of the Company,
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

                                      -13-
<PAGE>

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.  If, at any time, it is brought to the attention of any Director
that the Chairman has or may become absent or disabled and may thereby be unable
to perform the duties of Chairman for some period of time, the Lead Director
shall, as promptly as practicable upon his own initiative, or after notice from
another Director, convene a meeting (in person or by telephone conference call)
of the Outside Directors (who for purposes hereof shall consist of all Directors
who are not and have never been employees of the Company or any of its direct or
indirect subsidiaries) who shall decide whether the Chairman has become absent
or disabled.  Upon such determination, the Outside Directors shall designate an
Acting Chairman, who may be the Lead Director or any other Director of the
Company, and who shall exercise the power and duties of the Chairman until the
Outside Directors shall have determined that the Chairman can resume his duties
as Chairman or until a new Chairman has been elected by the Board of Directors.
The Acting Chairman, however, shall have no authority to make changes in the
persons holding any office at the executive payroll level of the Company or to
make changes in any such person's duties or responsibilities, or compensation or
benefits, without prior approval of the Board of Directors.  For purposes of
this Section, any action of the Outside Directors shall be by majority vote of
those present at a meeting of such Directors, provided that a majority of such
Directors shall constitute a quorum for such a meeting.

     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
management and direction of the affairs of the Company, subject to the control
of the Board of Directors, the Executive Committee and the Chairman. The
President shall have such other powers and duties as usually devolve upon the
President of a corporation and such further powers and duties as may be
prescribed by the Board of Directors, the Executive Committee or the chairman.
The President shall report to the Chairman.

                                      -14-
<PAGE>

     SECTION 5.  The Executive Vice Presidents, the Senior Vice Presidents and
the Vice Presidents shall have such powers and duties as may be prescribed for
them, respectively, by the Board of Directors, the Executive committee or the
Chairman.  Each of such officers shall report to the Chairman or such other
officer as the Chairman shall direct.

     SECTION 6.  The Secretary shall attend all meetings of the shareholders, of
the Board of Directors and of each committee of the Board of Directors, shall
keep a true and faithful record thereof in proper books and shall have the
custody and care of the corporate seal, records, minute books and stock books of
the Company and of such other books and papers as in the practical business
operations of the Company shall naturally belong in the office or custody of the
Secretary or as shall be placed in the Secretary's custody by order of the Board
of Directors or the Executive Committee.  The Secretary shall keep or cause to
be kept a suitable record of the addresses of shareholders and shall, except as
may be otherwise required by statute or the by-laws, sign and issue all notices
required for meetings of shareholders, of the Board of Directors and of the
committees of the Board of Directors.  Whenever requested by the requisite
number of shareholders or Directors, the Secretary shall give notice, in the
name of the shareholder or shareholders or Director or Directors making the
request, of a meeting of the shareholders or of the Board of Directors or of a
committee of the Board of Directors, as the case may be.  The Secretary shall
sign all papers to which the Secretary's signature may be necessary or
appropriate, shall affix and attest the seal of the Company to all instruments
requiring the seal, shall have the authority to certify the by-laws, resolutions
of the shareholders and Board of Directors and committees of the Board of
Directors and other documents of the Company as true and correct copies thereof
and shall have such other powers and duties as are commonly incidental to the
office of Secretary and as may be prescribed by the Board of Directors, the
Executive Committee or the Chairman.  The Secretary shall report to the Chairman
or such other officer as the Chairman shall direct.

     SECTION 7.  The Treasurer shall have charge of and be responsible for the
collection, receipt, custody and disbursement of the funds of the Company.  The
Treasurer shall deposit the Company's funds in its name in such banks, trust
companies or safe deposit vaults as the Board of Directors may direct.  Such
funds shall be subject to withdrawal only upon

                                      -15-
<PAGE>

checks or drafts signed or authenticated in such manner as may be designated
from time to time by resolution of the Board of Directors or of the Executive
Committee. The Treasurer shall have the custody of such books and papers as in
the practical business operations of the Company shall naturally belong in the
office or custody of the Treasurer or as shall be placed in the Treasurer's
custody by order of the Board of Directors or the Executive Committee. The
Treasurer shall have such other powers and duties as are commonly incidental to
the office of Treasurer or as may be prescribed for the Treasurer by the Board
of Directors, the Executive Committee or the Chairman. Securities owned by the
Company shall be in the custody of the Treasurer or of such other officers,
agents or depositaries as may be designated by the Board of Directors or the
Executive Committee. The Treasurer may be required to give bond to the Company
for the faithful discharge of the duties of the Treasurer in such form and in
such amount and with such surety as shall be determined by the Board of
Directors. The Treasurer shall report to the Chairman or such other officer as
the Chairman shall direct.

     SECTION 8.  The Comptroller shall be responsible for the executive
direction of the accounting organization and shall have functional supervision
over the records of all other departments pertaining to revenues, expenses,
money, securities, properties, materials and supplies.  The Comptroller shall
prescribe the form of all vouchers, accounts and accounting procedures, and
reports required by the various departments.  The Comptroller shall be
responsible for the preparation and interpretation of all ac  counting reports
and financial statements as required and for the proper review and approval of
all bills received for payment.  No bill or voucher shall be so approved unless
the charges covered by the bill or voucher shall have been previously approved
through job order, requisition or otherwise by the head of the department in
which it originated, or unless the Comptroller shall otherwise be satisfied of
its propriety and correctness. The Comptroller shall have such other powers and
duties as are commonly incidental to the office of Comptroller or as may be
prescribed for the Comptroller by the Board of Directors, the Executive
Committee or the Chairman.  The Comptroller may be required to give bond to the
Company for the faithful discharge of the duties of the Comptroller in such form
and in such amount and with such surety as shall be determined by the Board of
Directors.  The Comptroller shall

                                      -16-
<PAGE>

report to the Chairman or such other officer as the Chairman shall direct.

     SECTION 9.  Assistant Secretaries, Assistant Treasurers and Assistant
Comptrollers, when elected or appointed, shall respectively assist the
Secretary, the Treasurer and the Comptroller in the performance of the
respective duties assigned to such principal officers, and in assisting such
principal officer, each of such assistant officers shall for such purpose have
the powers of such principal officer. In case of the absence, disability, death,
resignation or removal from office of any principal officer, such principal
officer's duties shall, except as other wise ordered by the Board of Directors
or the Executive Committee, temporarily devolve upon such assistant officer as
shall be designated by the Chairman.

     SECTION 10.  At least once each year, the Chairman shall report (which may
be oral) to the Outside Directors (who for purposes hereof shall consist of all
Directors who are not and never have been employees of the Company or any of its
direct or indirect subsidiaries) on the status of a plan for succession to the
office of Chairman.

                               INDEMNIFICATION.

     SECTION 1.  (a) A Director of the Company shall not be personally liable to
the Company or its shareholders for monetary damages for breach of fiduciary
duty as a Director, except for liability (i) for any breach of the Director's
duty of loyalty to the Company or its shareholders, (ii) for acts or omissions
not in good faith or that involve intentional misconduct or a knowing violation
of law, (iii) under Section 8.65 of the Illinois Business Corporation Act of
1983, as amended, or (iv) for any transaction from which the Director derived an
improper personal benefit.  If the Illinois Business Corporation Act of 1983 is
amended to authorize corporate action further eliminating or limiting the
personal liability of Directors, then the liability of a Director of the Company
shall be eliminated or limited to the full extent permitted by the Illinois
Business Corporation Act of 1983, as so amended. Any repeal or modification of
this Section 1(a) by the shareholders of the Company shall not adversely affect
any right or protection of a

                                      -17-
<PAGE>

Director of the Company existing at the time of such repeal or modification.

trustee or fiduciary of another corporation, partnership, joint venture, trust
or other enterprise (including the heirs, executors, administrators or estate of
such person), shall be indemnified by the Company to the full extent permitted
by the Illinois Business Corporation Act of 1983 or any other applicable laws as
presently or hereafter in effect.  Without limiting the generality of the
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.

     SECTION 2.  The provisions of this Article shall be deemed to be a contract
between the Company and each Director or officer who serves in any such capacity
at any time while this Article is in effect, and any repeal or modification of
this Article shall not affect any rights or obligations hereunder with respect
to any state of facts then or theretofore existing or any action, suit or
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
entitled by law or otherwise, and shall continue as to a person who has ceased
to be a Director, officer, employee or agent and shall inure to the benefit of
the heirs, executors and administrators of such person.

     SECTION 4.  The Company may purchase and maintain insurance on behalf of
any person who is or was a Director, officer, employee or agent of the Company,
or who is or was serving at the request of the Company as a director, officer,
employee or agent of another corporation or of a partnership, joint venture,
trust or other enterprise, against any liability asserted

against such person and incurred by such person in any such capacity, or arising
out of his or her 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.

                                 ARTICLE VII.

                                MISCELLANEOUS.

approved by the Comptroller or by some other person or committee expressly
authorized by the Board of Directors, the Executive Committee, the Chairman or
the Comptroller to review and approve bills for payment.

Treasurer.

     SECTION 3.  Any and all shares of stock of any corporation owned by the
Company and any and all voting trust certificates owned by the Company calling

meeting of the shareholders of such corporation or at any meeting of the
holders of such certificates, as the case may be, by any one of the principal
officers of the Company upon any question which may be presented at such
meeting, and any such officer may, on behalf of the Company, waive any notice
required to be given of the calling of such meeting and consent to the holding
of any such meeting without notice.  Any such principal officer other than the
Secretary, acting together with the Secretary or an Assistant Secretary, shall
have authority to give to any person a written proxy, in the name of the Company
and under its corporate seal, to vote any or all shares of stock or any or all
voting trust certificates owned by the Company upon any question that may be
presented at any such meeting of shareholders or certificate holders, with full
power to waive any notice of the calling of such meeting and consent to the

                                   AGREEMENT

     THIS AGREEMENT is made by and between BellSouth Telecommunications, Inc.,
("BellSouth"), a Georgia corporation, and Mebtel Integrated Communications
Solutions, LLC, d/b/a Integrated Communications Solutions ("ICS"), a Delaware
company, and shall be deemed effective as of December 18, 1998. This agreement
may refer to either BellSouth or ICS or both as a "Party" or "Parties.

                                  WITNESSETH

     WHEREAS, BellSouth is a local exchange telecommunications company
authorized to provide telecommunications services in the states of Alabama,
Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South
Carolina, and Tennessee; and

     WHEREAS, ICS is an alternative local exchange telecommunications company
("CLEC") authorized to provide telecommunications services in the states of
Alabama, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina,
South Carolina, and Tennessee; and

     WHEREAS, the Parties wish to interconnect their facilities, purchase
unbundled elements, and exchange traffic specifically for the purposes of
fulfilling their obligations pursuant to sections 251 and 252 of the
Telecommunications Act of 1996 ("the Act").

     NOW THEREFORE, in consideration of the mutual agreements contained herein,
BellSouth and ICS agree as follows:

1.        Purpose

          The Parties agree that the rates, terms and conditions contained
          within this Agreement, including all Attachments, comply and conform
          with each Parties' obligations under sections 251 and 252 of the Act.
          The access and interconnection obligations contained herein enable ICS
          to provide competing telephone exchange service to residential and
          business subscribers within the territory of BellSouth. The Parties
          agree that ICS will not be considered to have offered interconnection
          in any state within BellSouth's region until such time as it has
          ordered interconnection facilities for the purposes of providing
          business and/or residential local exchange service to customers.

                                                                          Page 2

2.        Term of the Agreement

2.1       The term of this Agreement shall be two years, beginning  December 18,
          1998.

2.2       The Parties agree that by no later than one hundred and eighty (180)
          days prior to the expiration of this Agreement, they shall commence
          negotiations with regard to the terms, conditions and prices of local
          interconnection to be effective beginning on the expiration date of
          this Agreement ("Subsequent Agreement"). The Parties further agree
          that any such Subsequent Agreement shall be for a term of no less than
          two (2) years unless the Parties agree otherwise.

2.3       If, within one hundred and thirty-five (135) days of commencing the
          negotiation referred to in Section 2.2, above, the Parties are unable
          to satisfactorily negotiate new local interconnection terms,
          conditions and prices, either Party may petition the Commission to
          establish appropriate local interconnection arrangements pursuant to
          47 U.S.C. 252. The Parties agree that, in such event, they shall
          encourage the Commission to issue its order regarding the appropriate
          local interconnection arrangements no later than the expiration date
          of this Agreement. The Parties further agree that in the event the
          Commission does not issue its order prior to the expiration date of
          this Agreement, or if the Parties continue beyond the expiration date
          of this Agreement to negotiate the local interconnection arrangements
          without Commission intervention, the terms, conditions and prices
          ultimately ordered by the Commission, or negotiated by the Parties,
          will be effective retroactive to the day following the expiration date
          of this Agreement. Until the Subsequent Agreement becomes effective,
          the Parties shall continue to exchange traffic pursuant to the terms
          and conditions of this Agreement.

3.        Ordering Procedures

3.1       ICS shall provide BellSouth its Carrier Identification Code (CIC),
          Operating Company Number (OCN), Group Access Code (GAC) and Access
          Customer Name and Address (ACNA) code prior to placing its first
          order.

3.2       Detailed procedures for ordering and provisioning BellSouth services
          are set forth in BellSouth's Local Interconnection and Facility Based

                                                                          Page 3

          including valid address, available services and features, available
          telephone numbers, due date estimation on pre-order and calculation on
          firm order, and customer service records where applicable. Charges for
          Operational Support Systems (OSS) shall be as set forth in this
          agreement in Exhibit A of Attachment 1 and in Attachment 11.

4.        Parity

          The services and service provisioning that BellSouth provides ICS for
          resale will be at least equal in quality to that provided to
          BellSouth, or any BellSouth subsidiary, affiliate or end user. In
          connection with resale, BellSouth will provide ICS with pre-ordering,
          ordering, maintenance and trouble reporting, and daily usage data
          functionality that will enable ICS to provide equivalent levels of
          customer service to their local exchange customers as BellSouth
          provides to its own end users. BellSouth shall also provide ICS with
          unbundled network elements, and access to those elements, that is at
          least equal in quality to that which BellSouth provides BellSouth, or
          any BellSouth subsidiary, affiliate or other CLEC. BellSouth will
          provide number portability to ICS and their customers with minimum
          impairment of functionality, quality, reliability and convenience.

5.        White Pages Listings

          BellSouth shall provide ICS and their customers access to white pages
          directory listings under the following terms:

5.1       Listings. BellSouth or its agent will include ICS residential and
          business customer listings in the appropriate White Pages (residential
          and business) or alphabetical directories. Directory listings will
          make no distinction between ICS and BellSouth subscribers.

5.2       Rates. Subscriber primary listing information in the White Pages shall
          be provided at no charge to ICS or its subscribers provided that ICS

          the other Party for that portion of the Loss that would have been

          limitations of liability that such other Party included in its own
          tariffs at the time of such Loss.

          services, actions, duties, or obligations arising out of this
          Agreement.

          now or hereafter owned, controlled or licensable by a Party, is
          granted to the other Party or shall be implied or arise by estoppel.
          It is the responsibility of each Party to ensure at no additional cost
          to the other Party that it has obtained any necessary licenses in
          relation to intellectual property of third Parties used in its network
          that may be required to enable the other Party to use any facilities
          or equipment (including software), to receive any service, or to
          perform its respective obligations under this Agreement.

8.3       Indemnification. The Party providing a service pursuant to this
          Agreement will defend the Party receiving such service or data
          provided as a result of such service against claims of infringement
          arising solely from the use by the receiving Party of such service and
          will indemnify the receiving Party for any damages awarded based
          solely on such claims in accordance with Section 7 of this Agreement.

8.4       Claim of Infringement. In the event that use of any facilities or
          equipment (including software), becomes, or in reasonable judgment of
          the Party who owns the affected network is likely to become, the
          subject of a claim, action, suit, or proceeding based on intellectual
          property infringement, then said Party shall promptly and at its sole
          expense, but subject to the limitations of liability set forth below:

8.4.1     modify or replace the applicable facilities or equipment (including
          software) while maintaining form and function, or

8.4.2     obtain a license sufficient to allow such use to continue.

          respect to use of, or services provided through use of, the affected
          facilities or equipment (including software), but solely to the extent
          required to avoid the infringement claim.

8.5       Exception to Obligations. Neither Party's obligations under this
          Section shall apply to the extent the infringement is caused by: (i)
          modification of the facilities or equipment (including software) by
          the indemnitee; (ii) use by the indemnitee of the facilities or
          equipment (including software) in combination with equipment or
          facilities (including software) not provided or authorized by the
          indemnitor provided the facilities or equipment (including software)
          would not be infringing if used alone; (iii) conformance to
          specifications of the indemnitee which would necessarily result in
          infringement; or (iv) continued use by the indemnitee of the affected
          facilities or equipment (including software) after being placed on
          notice to discontinue use as set forth herein.

          trade secret information, including but not limited to, technical and
          business plans, technical information, proposals, specifications,
          drawings, procedures, customer account data, call detail records and

          Information and which employees agree to be bound by the terms of this
          Section. BellSouth and ICS will use the same standard of care to

          shall be void. A Party may assign this Agreement or any right,
          obligation, duty or other interest hereunder to an Affiliate company
          of the Party without the consent of the other Party. All obligations
          and duties of any Party under this Agreement shall be binding on all
          successors in interest and assigns of such Party. No assignment of
          delegation hereof shall relieve the assignor of its obligations under

          either Party may petition the Commission for a resolution of the
          dispute. However, each Party reserves any rights it may have to seek
          judicial review of any ruling made by the Commission concerning this
          Agreement.

12.       Taxes

12.1      Definition. For purposes of this Section, the terms"taxes" and "fees"
          shall include but not limited to federal, state or local sales, use,
          excise, gross receipts or other taxes or tax-like fees of whatever
          nature and however designated (including tariff surcharges and any
          fees, charges or other payments, contractual or otherwise, for the use
          of public streets or rights of way, whether designated as franchise
          fees or otherwise) imposed, or sought to be imposed, on or with
          respect to the services furnished hereunder or measured by the charges
          or payments therefore, excluding any taxes levied on income.

12.2      Taxes and Fees Imposed Directly On Either Seller or Purchaser.

12.2.1    Taxes and fees imposed on the providing Party, which are not permitted
          or required to be passed on by the providing Party to its customer,
          shall be borne and paid by the providing Party.

12.2.2    Taxes and fees imposed on the purchasing Party, which are not required
          to be collected and/or remitted by the providing Party, shall be borne
          and paid by the purchasing Party.

                                                                         Page 10

12.3      Taxes and Fees Imposed on Purchaser But Collected And Remitted By
          Seller.

12.3.1    Taxes and fees imposed on the purchasing Party shall be borne by the
          purchasing Party, even if the obligation to collect and/or remit such
          taxes or fees is placed on the providing Party.

12.3.2    To the extent permitted by applicable law, any such taxes and/or fees
          shall be shown as separate items on applicable billing documents
          between the Parties. Notwithstanding the foregoing, the purchasing
          Party shall remain liable for any such taxes and fees regardless of
          whether they are actually billed by the providing Party at the time
          that the respective service is billed.

12.3.3    If the purchasing Party determines that in its opinion any such taxes
          or fees are not payable, the providing Party shall not bill such taxes
          or fees to the purchasing Party if the purchasing Party provides
          written certification, reasonably satisfactory to the providing Party,
          stating that it is exempt or otherwise not subject to the tax or fee,
          setting forth the basis therefor, and satisfying any other
          requirements under applicable law. If any authority seeks to collect
          any such tax or fee that the purchasing Party has determined and
          certified not to be payable, or any such tax or fee that was not
          billed by the providing Party, the purchasing Party may contest the
          same in good faith, at its own expense. In any such contest, the
          purchasing Party shall promptly furnish the providing Party with
          copies of all filings in any proceeding, protest, or legal challenge,
          all rulings issued in connection therewith, and all correspondence
          between the purchasing Party and the taxing authority.

12.3.4    In the event that all or any portion of an amount sought to be
          collected must be paid in order to contest the imposition of any such
          tax or fee, or to avoid the existence of a lien on the assets of the
          providing Party during the pendency of such contest, the purchasing
          Party shall be responsible for such payment and shall be entitled to
          the benefit of any refund or recovery.

12-3.5    If it is ultimately determined that any additional amount of such a
          tax or fee is due to the imposing authority, the purchasing Party
          shall pay such additional amount, including any interest and penalties
          thereon.

12.3.6    Notwithstanding any provision to the contrary, the purchasing Party
          shall protect, indemnify and hold harmless (and defend at the
          purchasing Party's expense) the providing Party from and against any
          such tax or fee, interest or penalties thereon, or other charges or
          payable expenses (including reasonable attorney fees) with respect
          thereto, which are

                                                                         Page 11

          incurred by the providing Party in connection with any claim for or
          contest of any such tax or fee.

12.3.7    Each Party shall notify the other Party in writing of any assessment,
          proposed assessment or other claim for any additional amount of such a
          tax or fee by a taxing authority; such notice to be provided, if
          possible, at least ten (10) days prior to the date by which a
          response, protest or other appeal must be filed, but in no event later
          than thirty (30) days after receipt of such assessment, proposed
          assessment or claim.

12.4      Taxes and Fees Imposed on Seller But Passed On To Purchaser.

12.4.1    Taxes and fees imposed on the providing Party, which are permitted or
          required to be passed on by the providing Party to its customer, shall
          be borne by the purchasing Party.

12.4.2    To the extent permitted by applicable law, any such taxes and/or fees
          shall be shown as separate items on applicable billing documents
          between the Parties. Notwithstanding the foregoing, the purchasing
          Party shall remain liable for any such taxes and fees regardless of
          whether they are actually billed by the providing Party at the time
          that the respective service is billed.

12.4.3    If the purchasing Party disagrees with the providing Party's
          determination as to the application or basis for any such tax or fee,
          the Parties shall consult with respect to the imposition and billing
          of such tax or fee. Notwithstanding the foregoing, the providing Party
          shall retain ultimate responsibility for determining whether and to
          what extent any such taxes or fees are applicable, and the purchasing
          Party shall abide by such determination and pay such taxes or fees to
          the providing Party. The providing Party shall further retain ultimate
          responsibility for determining whether and how to contest the
          imposition of such taxes and fees; provided, however, that any such
          contest undertaken at the request of the purchasing Party shall be at
          the purchasing Party's expense.

12.4.4    In the event that all or any portion of an amount sought to be
          collected must be paid in order to contest the imposition of any such
          tax or fee, or to avoid the existence of a lien on the assets of the
          providing Party during the pendency of such contest, the purchasing

Service Provider (ESP) or Information Service Provider (ISP) until the
Commission, the FCC or a court of competent jurisdiction determines in a final
and nonappealable order that such traffic is Local Traffic. The Parties will
maintain billing records identifying all such Enhanced Service Provider and
Information Service Provider traffic and will adjust, if necessary, their mutual
compensation billing for such local traffic termination consistent with the
final Commission, FCC or court decision. The period of adjustment shall be from
the effective date of this Agreement to the date the order of the Commission,

interstate minutes of use for Terminating Party Pays services, such as 800
Services. The denominator includes all "non-intermediary", local, interstate,
intrastate, toll and access minutes of use adjusted for service provider number
portability less all minutes attributable to terminating Party pays services.

Percent Local Usage (PLU) is defined as a factor to be applied to intrastate
terminating minutes of use. The numerator shall include all "non-intermediary"
local minutes of use adjusted for those minutes of use that only apply local due
to Service Provider Number Portability. The denominator is the total intrastate
minutes of use including local, intrastate toll, and access, adjusted for
Service Provider Number Portability less intrastate terminating Party pays
minutes of use.
