Within 15 days following receipt by the Secretary of a shareholder notification of proposed business pursuant hereto, the Corporation shall advise the shareholder of any deficiencies in the notification. The notifying shareholder may cure such deficiencies within 15 days after receipt of such advice, failing which the shareholder's notification shall be deemed invalid.

SECTION 6.Quorum for Shareholder Meetings. 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 shareholders are entitled to cast upon a 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.

SECTION 7.Votes Per Share. Except as otherwise provided in the Articles 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 Corporation. Except as may be explicitly provided for by the Articles with respect to the election of one or more directors by holders of one or more series of Preferred Stock, in the election of directors stockholders shall be entitled to cast for any candidate for election as a director only one vote per share and shall not be entitled to cumulate their votes and cast them for one candidate or distribute them among any two or more candidates.

SECTION 8.Proxies. 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.

SECTION 9.Required Vote for Shareholder Action. Except in respect of the election of directors (as to which a plurality vote shall be required) and subject to Section 11 of this Article II, all questions submitted to the stockholders and all actions by the stockholders shall be decided by the affirmative vote of the shareholders present, in person or by proxy, entitled to cast at least a majority of the votes which all shareholders present are entitled to vote on the matter, unless otherwise provided by the Articles, the Bylaws or by law. For purposes of this section, in the event that a holder of shares of a class or series that is entitled to vote on a matter is present in person or by proxy at a meeting but is not permitted by reason of a legal disability or by a contractual restriction or otherwise to vote the shares such holder holds on such matter, the shares held by such holder and not so permitted to be voted shall nevertheless be considered

entitled to vote and present for purposes of determining the number of votes required for stockholder action.

SECTION 10. Ballots; Judges of Election. 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 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 their 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 in advance of the convening of the meeting or at the meeting by the person or officer acting as chairman of the meeting. 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.

(a)To the fullest extent and in the manner permitted by law, any action required or permitted to be taken at a meeting of the stockholders or of a class or series of stockholders may be taken without a meeting of the stockholders or of such class or series of stockholders upon the consent in writing signed by such stockholders who would have been entitled to vote the minimum number of votes that would be necessary to authorize the action at a meeting at which all the stockholders entitled to vote thereon were present and voting. The consents shall be filed with the Secretary.

(b)In order that the Corporation may determine the shareholders entitled to consent to corporate action in writing without a meeting, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which date shall not be more than 30 days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. Any shareholder of record seeking to have the shareholders authorize or take corporate action by written consent shall, by written notice to the Secretary of the Corporation, request the Board of Directors to fix a record date. The Board of Directors shall promptly, but in all events within 30 days after the date on which such a request is received, adopt a resolution fixing the record date and the record as so established by the Board of Directors shall not be less than 15 days nor more than 30 days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. If no record date has been fixed by the Board of Directors within 30 days of the date on which such a request is received, subject to the shareholder's compliance with Article II, Section 11(c), the record date for determining shareholders entitled to consent to corporate action in writing without a meeting, when no prior action by the Board of Directors is required by applicable law, shall be the close of business on the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation by delivery to its registered office in the Commonwealth of Pennsylvania, its principal place of

business, or an officer or agent of the Corporation having custody of the book in which proceedings of meetings of the shareholders are recorded, to the attention of the Secretary of the Corporation. Delivery made to the Corporation's registered office shall be by hand or by certified or registered mail, return receipt requested. If no record date has been fixed by the Board of Directors and prior action by the Board of Directors is required by applicable law, the record date for determining shareholders entitled to consent to corporate action in writing without a meeting shall be at the close of business on the date on which the Board of Directors adopts the resolution taking such prior action.

(c)Advance Notice of Shareholder Nominations of Candidates for Election as Directors and Other Matters Presented by Shareholders to be Acted on by Written Consent. In addition to the provisions of Article II, Section 11(b) regarding the requirement that a shareholder of record seeking to have the shareholders authorize or take corporate action by written consent shall request the Board of Directors to fix a record date, in connection with any such authorization of corporate action by written consent, only such nominations of candidates for election as directors (as and to the extent such candidates are permitted to be elected by action by written consent) and other business as is properly the subject of such an action by written consent of shareholders in accordance with this paragraph may be transacted. To be properly the subject of an action by written consent of shareholders, any nominations of candidates for election as directors and other proposed business to be effected by means of such action by written consent must be either (a) specified in the notice of the solicitation of written consents (or any supplement thereto) given by or at the direction of the Board of Directors or

(b)if to be acted upon at the request of a shareholder of record seeking to have the shareholders authorize or take corporate action by written consent, then written notification of such proposed business must have been received by the Secretary of the Corporation from such shareholder of record not later than the close of business on the 30th day prior to the record date set in accordance with Article II, Section 11(b) for the determination of shareholders entitled to act by written consent in lieu of a meeting with respect to the election of such candidates for director or the taking of such corporate action; provided, however, that (i) if the Board of Directors fixes a record date for the determination of shareholders entitled to act by written consent in lieu of a meeting that is less than 30 days after a request therefor is made pursuant to Article II, Section 11(b), then written notification of such proposed business must have been received by the Secretary of the Corporation from such shareholder of record not later than the close of business on the 15th day prior to such record date or (ii) if no such record date is fixed by the Board of Directors pursuant to Article II, Section 11(b), then written notification of such proposed business must have been received by the Secretary of the Corporation from such shareholder of record not later than the record date as otherwise established in accordance with Article II, Section 11(b). Such shareholder notification shall (i) to the extent such notification relates to proposed business other than the nomination of candidates for election as directors, set forth (a) the nature of and reasons for the proposal in reasonable detail, and shall include the proposed text of any proposal regarding such business (including the text of any resolutions proposed for consideration and, if such business includes a proposal to amend these Bylaws, the text of the proposed amendment), and (b) the reasons for conducting such business by action by written consent, (ii) as to the shareholder giving notification, and the beneficial owner, if any, on whose behalf the notification is being made,

(b)the class and series of all shares of the Corporation that are beneficially owned of record by such persons and any affiliates or associates of such persons;

(c)the name of each nominee holder of shares of all stock of the Corporation owned beneficially but not of record by such persons or any affiliates or associates of such persons, and the number of such shares of stock of the Corporation held by each such nominee holder;

(d)whether and the extent to which any derivative instrument, swap, option, warrant, short interest, hedge or profit interest or other transaction has been entered into by or on behalf of such persons, or any affiliates or associates of such persons, with respect to stock of the Corporation;

(e)whether and the extent to which any other transaction, agreement, arrangement or understanding (including any short position or any borrowing or lending of shares of stock of the Corporation) has been made by or on behalf of such persons, or any affiliates or associates of such persons, the effect or intent of any of the foregoing being to mitigate loss to, or to manage risk or benefit of stock price changes for, such persons, or any affiliates or associates of such persons, or to increase or decrease the voting power or pecuniary or economic interest of such persons, or any affiliates or associates of such persons, with respect to stock of the Corporation;

(f)a description of all agreements, arrangements, or understandings (whether written or oral) between or among such persons, or any affiliates or associates of such persons, and any other person or persons (including their names) in connection with or relating to (A) the Corporation or (B) the proposal, including any material interest in, or anticipated benefit from the proposal to such persons, or any affiliates or associates of such persons; and

(g)any other information relating to such persons that would be required to be disclosed in a proxy statement or other filing required to be made in connection with the solicitation of proxies by such persons with respect to the proposed business to be brought by such persons before an annual meeting pursuant to Section 14 of the Exchange Act, and the rules and regulations promulgated thereunder;

and (iii) to the extent such notification relates to the nomination of candidates for election as directors, set forth the information specified in subclauses (a), (b), (g), (h) , (i), (j) and (k) of Article II, Section 4 of these Bylaws. Within 15 days following receipt by the Secretary of a shareholder notification of nominations of candidates for election as directors or other proposed business to be acted on by written consent pursuant hereto, the Corporation shall advise the shareholder of any deficiencies in the notification.

In all other respects, the Board may, by resolution adopted by a majority of the Whole Board, establish rules of procedure for a committee, including designating a member of a committee as its chair.

Limitation on Directors' Personal Liability; Indemnification of Directors, Officers, Employees and Agents

SECTION 1.Limitation on Directors' Personal Liability. A director of the Corporation 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 Subchapter B of Chapter 17 of the Pennsylvania Business Corporation Law of 1988, as amended, 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.

(a)Indemnification of Directors and Officers. The Corporation shall indemnify to the full extent 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, legislative or investigative, and whether by or in the right of the Corporation or otherwise asserted) by reason of the fact that the person

(i)

is or was a director or officer of the Corporation or

(ii)

while a director or officer of the Corporation, either

(A)serves or served as a director, officer, partner, member, trustee, employee or agent of any subsidiary of the Corporation or other related enterprise at the request of the Corporation or in connection with a related employee benefit plan of the Corporation, any subsidiary of the Corporation or any such enterprise,

(B)serves or served as a director, officer, partner, member, trustee, employee or agent of any other unrelated enterprise (including any charitable organization) in furtherance of the interests of, and at the specific written request of the Corporation, or in connection with a related employee benefit plan of such enterprise,

against any expenses, judgments, fines, and amounts paid in settlement actually and reasonably incurred in defending or responding to any such pending or threatened action, suit or proceeding (including any incurred in connection with any actions brought by or in the right of the Corporation). A resolution or other action by the Corporation or subsidiary electing, nominating or proposing a person to a position referred to in this subsection 2(a) shall constitute a specific written request of the Corporation sufficient for the purposes of this Section. Upon written request of a person claiming to be entitled to indemnification hereunder and specifying the expenses, judgments, fines and amounts paid in settlement against which indemnity is sought, the Corporation shall, as soon as practicable and in any event within 90 days of its receipt of such request, make a determination, in such manner as is required by law, as to the entitlement of such person to indemnification against such expenses as provided by this subsection 2(a). Such a determination, however, shall not be conclusive as to such person's entitlement to indemnification pursuant to this subsection 2(a) and such person may seek to enforce an entitlement to indemnification pursuant to this subsection 2(a) by appropriate proceedings in any court of competent jurisdiction by showing that, notwithstanding such determination, such person satisfied the standard of conduct required by law to be satisfied in order for such person to be entitled to indemnification from the Corporation as permitted by law.

(b)Advancement of Expenses. Expenses reasonably incurred by a person referred to in subsection 2(a) above in defending or responding to a civil, criminal, administrative, legislative or investigative action, suit or proceeding shall be paid by the

Corporation 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 determined that such person is not entitled to be indemnified by the Corporation against such expenses or, in the case of a criminal action in which a judgment has been entered against such person, the Board of Directors so determines.

(c)Indemnification of Employees and Agents. The Corporation may, upon authorization by the board of directors, the President or any other officer designated by the board of directors, indemnify, or agree to indemnify, and advance expenses to any person who is or was an employee or agent of the Corporation or any subsidiary of the Corporation to the same extent (or any lesser extent) to which it may indemnify and advance expenses to a director or officer of the Corporation in accordance with subsection 2(b) above.

(d)Non-Exclusivity. 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 Corporation having the express authority to enter such agreements or make other provision for the indemnification of and advancement of expenses to any or all of its representatives as the Board of Directors deems appropriate, including corporate policies and the creation of one or more funds or equivalent guarantees for indemnity payments and or expense advancements to present or future indemnified persons.

(e)Continuing Contractual Rights. 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. Expenses reasonably incurred by a person in successfully enforcing a right to indemnification or advancement of expenses provided to such person by, or as permitted by, this Section 2 shall be paid by the Corporation.

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

The Corporation shall have a seal that shall contain the words "Armstrong World Industries, Inc." and may be affixed to documents of the Corporation as prima facie evidence of the act of the Corporation to the extent provided by law.

SECTION 1.Form of Share Certificates. Shares of the Corporation may be represented by certificates or may be uncertificated, but shareholders shall be entitled to receive share certificates representing their shares as provided by law. Share certificates shall be in such form as the Board may from time to time determine and shall be signed by the President or one of the Vice Presidents and countersigned by the Treasurer or an Assistant Treasurer or the Secretary or an Assistant Secretary and embossed with the seal of the Corporation or, if not so signed and sealed, shall bear the engraved or printed facsimile signatures of the officers

authorized to sign and the engraved or printed facsimile of the seal of the Corporation. The death, incapacity, resignation or removal of an officer who signed or whose facsimile signature appears on a share certificate shall not affect the validity of the share certificate.

SECTION 2.Transfers of Record. The shares of the Corporation shall, upon the surrender and cancellation of the certificate or certificates representing the same, be transferred upon the books of the Corporation at the request of the holder thereof, named in the surrendered certificate or certificates, in person or by his legal representatives or by his attorney duly authorized by written power of attorney filed with the Corporation or its transfer agent. In case of loss or destruction of a certificate of stock, another may be issued in lieu thereof in such manner and upon such terms as the Board shall authorize.

SECTION 3.Record Dates. The Board of Directors may set a time, not more than 90 days prior to the date of any meeting of the shareholders, or the date set for the payment of any dividend or distribution or the date for the allotment of rights, or the date when any change or conversion or exchange of shares stock will be made or go into effect, as a record date for the determination of the shareholders entitled to notice of, or to vote at, any such meeting, or entitled to receive payment of any such dividend or distribution, or to receive any such allotment of rights, or to exercise the rights in respect to any such change, conversion, or exchange of shares of the Corporation. In such case, only such shareholders as shall be shareholders of record on the date so set shall be entitled to notice of, or to vote at, such meeting, or to receive payment of such dividend or distribution, or to receive such allotment of rights, or exercise such rights, as the case may be, notwithstanding any transfer of shares of the Corporation on the books of the Corporation after any record date set as aforesaid.

The fiscal year of the Corporation shall end on the 31st day of December. Without limiting any other financial reporting obligation the Corporation may have, the Board shall mail or otherwise 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 end of such year, together with a statement of income and expense for such year, prepared so as to present fairly the financial condition and results of its operations of the Corporation in accordance with generally accepted accounting principles. Such financial statements shall have been audited in accordance

with generally accepted auditing standards by a firm of independent certified public accountants and shall be accompanied by such firm's opinion as to the fairness of the presentation thereof.

Unless the Corporation consents in writing to the selection of an alternative judicial forum (an “Alternative Forum Consent”), the sole and exclusive judicial forum for (i) any derivative action or proceeding brought on behalf of the Corporation, (ii) any action asserting or alleging any claim of breach of a fiduciary duty owed by any director, officer, shareholder, employee or agent of the Corporation to the Corporation or the Corporation's shareholders, (iii) any action asserting or alleging any claim against the Corporation or against any director, officer, shareholder, employee or agent of the Corporation arising pursuant to, or involving any application, interpretation, enforcement or determination of validity of, any provision of the Pennsylvania Associations Code, the Business Corporation Law of the Commonwealth of Pennsylvania, the Articles of Incorporation of the Corporation or these Bylaws (as any of the foregoing may be amended and in effect from time to time), or (iv) any action asserting or alleging any claim against the Corporation or against any director, officer, shareholder, employee or agent of the Corporation governed by or involving the internal affairs doctrine of the Commonwealth of Pennsylvania; shall in each such instance, be a state court located within Lancaster County, Pennsylvania or, if no state court located within Lancaster County has jurisdiction over any such case or proceeding, the U.S. federal district court for the Eastern District of Pennsylvania, in each such case, unless such state or federal courts, as applicable, have dismissed a prior action by the same plaintiff asserting the same claims because such court lacked personal jurisdiction over an indispensable party named as a defendant therein. Without limiting any of the foregoing, nothing contained in this Article IX is intended to limit, determine or address the merits or substance of any action or proceeding (including, whether any action or proceeding should be commenced or maintained against the Corporation or against any of the Corporation’s directors, officers, shareholders, employees or agents, or whether any particular type or form of remedy or relief should be sought or is available against the Corporation or against any of its directors, officers or employees), but instead, the provisions of this Article IX are solely procedural in nature and govern only the exclusive location, forum and venue for the commencement of actions and proceedings expressly enumerated in clauses (i) through (iv) of the immediately preceding sentence. Failure to enforce the foregoing provisions would cause the Corporation irreparable harm and the Corporation shall be entitled to equitable relief, including injunctive relief and specific performance, to enforce the foregoing provisions. Any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of the Corporation shall be deemed to have notice of and consented to the provisions of this Article IX. The existence of any prior Alternative Forum Consent shall not act as a waiver of the Corporation’s ongoing consent right as set forth above in this Article IX with respect to any current or future actions or claims.

The Bylaws, as from time to time in effect, may be amended, modified or repealed, in whole or in part, at any time and from time to time in any respect by either (i) the shareholders, by the affirmative vote of the holders of a majority of the outstanding shares entitled to vote on the matter, or (ii) by the Board, by the affirmative vote of a majority of the Whole Board, in either case except as otherwise provided by law or by the Articles or by Section 2 of this Article of the Bylaws (as in effect at the Effective Time).

The foregoing Bylaws were originally adopted before the Effective Time by action of the sole shareholder of the Corporation and became effective upon the filing with the office of the Secretary of State of the Commonwealth of Pennsylvania of Amended and Restated Articles of Incorporation of the Corporation and the effectiveness of such Amended and Restated Articles of Incorporation in accordance with law on October 2, 2006 (the "Effective Time").
