                                  ARTICLE I.

                                    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 for transfer
shall be canceled and filed.

         SECTION 4.  For the purpose of determining stockholders entitled to
notice of or to vote at any meeting of stockholders, or stockholders entitled to
receive payment of any dividend, or in order to make a determination of
stockholders for any other proper purpose, the Board of Directors may fix in
advance a date as the record date for any such determination for stockholders,
such date in any case to be not more than sixty days and, for a meeting of
stockholders, 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 or 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.

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 stockholders may be called by the

postage thereon prepaid.

         SECTION 4.  At all meetings of the stockholders, 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
stockholders 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

share of stock shall be entitled to one vote on each matter submitted for a
vote. In all elections for Directors, every stockholder shall have the right to
vote the number of shares owned by such stockholder 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 stockholder may vote either in
person or by proxy. A stockholder 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.  The Secretary of the Company shall make, within twenty days
after the record date for a meeting of stockholders of the Company or ten days
before such meeting, whichever is earlier, a complete list of the stockholders
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 stockholder, and to
copying at such stockholder'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 stockholder during the
whole time of the meeting.

         SECTION 7.  The Chairman and the Secretary of the Company shall, when
present, act as chairman and secretary, respectively, of each meeting of the
stockholders.

         SECTION 8.  At any meeting of stockholders, the chairman of the meeting
may, or upon the request of any stockholder 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
stockholders.

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 4.  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, determine.

                                   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

 
                                     -11-

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, except that one person may not at
the same time hold the office of Chairman or President and the office of
Secretary. 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
stockholders and of the Board of Directors. The Chairman shall have authority to
call special meetings of the stockholders 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 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
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

 
                                     -12-

the Board of Directors, the Executive Committee or the Chairman. The President
shall report to the Chairman.

         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
stockholders, 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
