                        ARMSTRONG WORLD INDUSTRIES, INC.
                             LANCASTER, PENNSYLVANIA
                           as amended November 9, 2000

                                    ARTICLE I

                                     Office

         The principal office of the Company shall be in Lancaster,
Pennsylvania.

         All meetings of directors and stockholders shall be held at the
principal office of the Company unless the Board of Directors shall decide
otherwise, in which case such meetings may be held within or without the
Commonwealth of Pennsylvania as the Board may from time to time direct.

                                   ARTICLE II

                             Stockholders' Meetings

         An annual meeting of stockholders shall be held in each calendar year
on such date and at such time as may be fixed by the Board of Directors for the
purpose of electing directors and the transaction of such other business as may
properly come before the meeting.

         Special meetings of the stockholders may be called at any time by the
President or the Board of Directors. At any time, upon written request of any
person or persons who have duly called a special meeting, it shall be the duty
of the Secretary to fix the date of the meeting, to be held not more than sixty
days after the receipt of the request, and to give due notice thereof. If the
Secretary shall neglect or refuse to fix the date of the meeting and give notice
thereof, the person or persons calling the meeting may do so.

         Special meetings of the holders of No Par Preferred Stock for the
purpose of electing directors may be called as provided in the Articles of
Incorporation, as amended.

         Written notice of the place, day, and hour of all meetings of
stockholders and, in the case of a special meeting, of the general nature of the
business to be transacted, shall be given to each stockholder of record entitled
to vote at the particular meeting either personally or by sending a copy of the
notice through the mail, or by telegram, charges prepaid, to the address of the
stockholder appearing on the books of the Company or supplied by him to the
Company for the purpose of notice. Except as otherwise provided by these bylaws
or by law, such notice shall be given at least five days before the date of the
meeting by the President, Vice President, or Secretary. A waiver in writing of
any written notice required to be given, signed by the person entitled to such
notice, whether before or after the time stated, shall be deemed equivalent to
the giving of such notice. Attendance of a person,


either in person or by proxy, at any meeting shall constitute a waiver of notice
of such meeting, except where a person attends a meeting for the express purpose
of objecting to the transaction of any business because the meeting was not
lawfully called or convened.

         Nominations of candidates for election to the Board of Directors may be
made by the Board of Directors or by any stockholder of the Company entitled to
notice of, and to vote at, any meeting called for the election of directors.

         At any meeting of the stockholders, the presence, in person or by
proxy, of stockholders entitled to cast at least a majority of the votes which
all stockholders are entitled to cast upon any matter shall constitute a quorum
for the transaction of business upon such matter, and the stockholders present
at a duly organized meeting can continue to do business until adjournment,
notwithstanding the withdrawal of enough stockholders to leave less than a
quorum. If a meeting cannot be organized because a quorum has not attended,
those present may, except as otherwise provided by law, adjourn the meeting to
such time and place as they may determine, but in the case of any meeting called
for the election of directors, those who attend the second of such adjourned
meetings, although less than a quorum, shall nevertheless constitute a quorum
for the purpose of electing directors.

         Except as otherwise provided in the Articles of Incorporation, as
amended, or by law, every stockholder of record shall have the right, at every
stockholders' meeting, to one vote for every share standing in his name on the
books of the Company. In each election of directors, every stockholder entitled
to vote shall have the right to multiply the number of votes to which he may be
entitled by the total number of directors to be elected, and he may cast the
whole number of such votes for one candidate or he may distribute them among any
two or more candidates.

         Every stockholder entitled to vote at a meeting of stockholders may
authorize another person or persons to act for him by proxy. A proxy may be
submitted to the Secretary by a stockholder in writing, by telephone,
electronically or any other means permitted by law.

         All questions shall be decided by the vote of the stockholders present,
in person or by proxy, entitled to cast at least a majority of the votes which
all stockholders present are entitled to cast, unless otherwise provided by the
Articles of Incorporation, as amended, or by law.

         Elections for directors need not be by ballot except on demand made by
a stockholder at the election and before the voting begins. In advance of any
meeting of stockholders, the Board of Directors may appoint judges of election
who need not be stockholders to act at such meeting or any adjournment thereof,
and if such appointment is not made, the chairman of any such meeting may, and
on request of any stockholder or his proxy shall, make such appointment at the
meeting. The number of judges shall be one or three; and if appointed at a
meeting on request of one or more stockholders or proxies, the majority of the
shares present and entitled to vote shall determine whether one or three judges
are to be appointed. No person who is a candidate for office shall act as a
judge. In case any person appointed as judge fails to appear or fails or refuses
to act, the vacancy may be filled by appointment made by the Board of Directors
in advance of the convening of the meeting or at the meeting by the

                                       2


person or officer acting as chairman. On request of the chairman of the meeting
or of any stockholder or his proxy, the judges shall make a report in writing of
any challenge or question or matter determined by them and execute a certificate
of any fact found by them.

                                   ARTICLE III

                                    Directors

         SECTION 1. The business and affairs of the Company shall be managed
under the direction of a Board of Directors. The directors need not be
stockholders of the Company. The Board shall consist of not less than three (3)
directors, the exact number to be fixed from time to time by the Board of
Directors pursuant to a resolution adopted by a majority vote of the directors
then in office, such number being in addition to any directors that the holders
of any class of preferred stock, voting as a class, may be entitled to elect as
provided in the Articles of Incorporation, as amended, or in a resolution of the
Board establishing any series of preferred stock.

         The directors, other than the directors to be elected by the holders of
No Par Preferred Stock, voting as a class, shall be classified in respect to the
time for which they shall severally hold office by dividing them into three
classes, each consisting, as nearly as possible, of one-third of the whole
number of such directors. At each annual meeting, the successors to the class of
directors whose terms expire that year shall be elected to hold office for the
term of three years. Each such director shall hold office for the term for which
he is elected and until his successor shall have been elected and qualified. Any
vacancy in the office of any such director shall be filled by an election by the
Board for the unexpired term.

         Directors to be elected by the holders of No Par Preferred Stock,
voting as a class, shall be elected and hold office as provided in the Articles
of Incorporation, as amended.

         SECTION 2. The Board of Directors shall hold an annual meeting, without
notice, immediately following the annual meeting of the stockholders and shall
elect a President, such number of Vice Presidents and Operation or Division
Presidents as the Board may deem advisable, a Secretary, a Treasurer, a
Controller, and such Assistant Secretaries and Assistant Treasurers as the Board
may deem advisable. The Board may also at its discretion elect a Chairman of the
Board. Unless sooner removed by the Board, all officers shall hold office until
the next annual meeting of the Board and until their successors shall have been
elected. The Board shall also, from time to time, elect such other officers and
agents as it deems advisable.

         Any two or more offices may be held by the same person except the
offices of President and Secretary, but in no case shall the same person act in
the same matter in two such official capacities.

         SECTION 3. All vacancies in office shall be filled by the Board of
Directors or by the stockholders, and the Board shall have power to define the
duties of all officers and agents and fix their compensation and may remove at
its discretion any officer or agent.

                                       3


         SECTION 4. The Board of Directors shall hold meetings at such times and
places as it may determine. Directors may participate in a meeting of the Board
or a Committee thereof by conference telephone or similar communications
equipment by means of which all persons participating in the meeting can hear
each other. No notice of regular meetings of the Board need be given. Special
meetings of the Board may be called by the President or a Vice President or the
Secretary or by any two directors by giving written notice at least twenty-four
hours in advance of the place, day and hour of the meeting to each director,
either personally or by facsimile, telegram, or other means permitted by law.

         Attendance at any meeting of the Board shall be a waiver of notice
thereof. If all the members of the Board are present at any meeting, no notice
shall be required. A majority of the whole number of the directors shall
constitute a quorum for the transaction of business, but if at any meeting a
quorum shall not be present, the meeting may adjourn from time to time until a
quorum shall be present.

         SECTION 5. The Board of Directors shall cause to be sent to the
stockholders, within 120 days after the close of each fiscal year, financial
statements which shall include a balance sheet as of the close of such year,
together with statements of income and surplus for such year, prepared so as to
present fairly its financial condition and results of its operations. Such
financial statements shall have been examined in accordance with generally
accepted auditing standards by a firm of independent certified public
accountants selected by the Board and shall be accompanied by such firm's
opinion as to the fairness of the presentation thereof.

         SECTION 6. The Board of Directors may, by resolution adopted by a
majority of the whole Board, designate one or more committees, each committee to
consist of two or more of the directors of the Company. The Board may designate
one or more directors as alternate members of any committee, who may replace any
absent or disqualified member at any meeting of the committee. Any such
committee to the extent provided in such resolution shall have and exercise the
authority of the Board in the management of the business and affairs of the
Company.

         Unless otherwise provided in the Articles of Incorporation, as amended,

                                   ARTICLE IX

                  Limitation on Directors' Personal Liability;
                    Indemnification of Directors and Officers

         SECTION 1. A director of the Company shall not be personally liable for
monetary damages for any action taken or failure to take any action unless the
director has breached or failed to perform the duties of his or her office under
Section 8363 of the Pennsylvania Directors' Liability Act and such breach or
failure to perform constitutes self-dealing, willful misconduct or recklessness;
provided, however, that the foregoing provision shall not eliminate or limit the
liability of a director (i) for any responsibility or liability of such director
pursuant to any criminal statute, or (ii) for any liability of a director for
the payment of taxes pursuant to local, state or federal law.

         SECTION 2. The Company shall indemnify to the full extent authorized or
permitted by law any person made, or threatened to be made, a party to or
otherwise involved in (as a witness or otherwise) an action, suit or proceeding
(whether civil, criminal, administrative or investigative, and whether by or in
the right of the Company or otherwise) by reason of the fact that the person is
or was a director or officer of the Company or while a director or officer of
the Company, either serves or served as a director, officer, trustee, employee
or agent of any other related enterprise or in connection with a related
employee benefit plan at the request of the Company or serves or served as a
director, officer, trustee, employee or agent of any other unrelated enterprise
at the specific written request of the Company against any expenses and
liability actually incurred including without limitation judgments and amounts
paid or to be paid in settlement of and in actions brought by or in the right of
the Company. Expenses incurred by such a person in defending a civil or criminal
action, suit or proceeding or in enforcing any right under this Article shall be
paid by the Company in advance of the final disposition of the action, suit or
proceeding upon receipt of an undertaking by or on behalf of such person to
repay such amount to the extent it shall ultimately be

                                       7


determined that such person is not entitled to be indemnified by the Company or,
in the case of a criminal action, the majority of the Board of Directors so
determines. The right to indemnification and advancement of expenses conferred
in this Section shall not be deemed exclusive of any other rights to which any
person indemnified may be entitled under any agreement, vote of stockholders or
directors or otherwise, the Company having the express authority to enter such
agreements as the Board of Directors deems appropriate for the indemnification
of and advancement of expenses, including the creation of a fund therefor or
equivalent guarantee, to present or future directors and officers of the Company
in connection with their service as director or officer of the Company or their
service as director, officer, trustee, employee or agent of any other enterprise
or in connection with an employee benefit plan at the request of the Company.
The right to indemnification and the advancement of expenses provided in this
Section shall be a contract right, shall continue as to a person who has ceased
to serve in the capacities described herein, and shall inure to the benefit of
the heirs, executors and administrators of such person.

         SECTION 3. No amendment, alteration or repeal of this Article IX, nor
the adoption of any provision inconsistent with this Article IX, shall adversely
affect any limitation on the personal liability of a director or officer, or the
rights of a director or officer to indemnification and advancement of expenses,
existing at the time of such amendment, modification or repeal, or the adoption
of such an inconsistent provision.
