Item 1.

Security and Issuer

This Amendment No. 2 (“Amendment No. 2”) amends and supplements the statement on Schedule 13D originally filed by the Reporting Persons on August 11, 2009, as amended by Amendment No. 1 filed on September 3, 2009 (as so amended, the “Original Schedule 13D,” and, as further amended by this Amendment No. 2, the “Schedule 13D,”) relating to Issuer Common Stock. Unless otherwise indicated, each capitalized term used but not defined in this Amendment No. 2 shall have the meaning assigned to such term in the Original Schedule 13D.

Item 3.

This Amendment No. 2 supplements and amends Item 3 of the Original Schedule 13D by replacing the last sentence of the second paragraph with the following:

With respect to the Tender Offer commenced by Armor on September 3, 2009 and completed on October 2, 2009, the purchase price for the 1,892 shares of Issuer Common Stock acquired by Armor pursuant to the terms of the Tender Offer was funded by the TPG Funds, utilizing equity contributions from the limited partners of the TPG Funds. Any future purchase by Armor of additional shares of Issuer Common Stock, as described under the heading“Additional Purchases” in Item 4 below, will also be funded by the TPG Funds, utilizing equity contributions from the limited partners of the TPG Funds.

Item 4.

Purpose of Transaction

This Amendment No. 2 supplements and amends Item 4 of the Original Schedule 13D by:

(1)	replacing the second paragraph under the heading“Tender Offer” with the following:

The Tender Offer was commenced on September 3, 2009 and completed on October 2, 2009. Armor acquired 1,892 shares of Issuer Common Stock pursuant to the terms of the Tender Offer.

(2) inserting the following after the subsection titled “Tender Offer” and prior to the subsection titled “Shareholders’ Agreement”):

Additional Purchases

Armor intends to acquire additional shares of Issuer Common Stock. The timing and amount of such acquisitions will depend on Armor’s ongoing evaluation of AWI, prevailing market and economic conditions and/or other investment considerations. Armor’s acquisition of additional shares of Issuer Common Stock is subject to the provisions of the Shareholders’ Agreement, the NDA and applicable legal restrictions, including the restriction under the NDA that through May 25, 2010 Armor’s additional purchases cannot in the aggregate exceed 4,434,043 shares of Issuer Common Stock. Armor will acquire additional shares of Issuer Common Stock through open market purchases and/or privately.

Armor is filing the Notification and Report Form for Certain Mergers and Acquisitions pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”) with the Federal Trade Commission (the “FTC”) and the Antitrust Division of the Department of Justice (the “Antitrust Division”) in connection with the additional purchases on April 1, 2010. The waiting period under the HSR Act is scheduled to expire on May 3, 2010, unless earlier terminated by the FTC and the Antitrust Division, or extended by a request for additional information.

(3) adding the following sentence after the last paragraph under the heading“Composition of AWI’s Board of Directors”:

Armor nominated David Bonderman and Kevin Burns as the initial TPG Directors and the Trust nominated James Melville and Edward Steiner as the initial Trust Directors. On September 22, 2009, the

AWI Board of Directors elected by unanimous written consent Messrs. Bonderman, Burns, Melville and Steiner to the Board of Directors.

Item 5.
