Explanation of Responses:

( 1 )The price of $53.80 represents the public offering price of $54.25 per share of common stock of Armstrong World Industries, Inc. (the "Common Stock") less the underwriter's discount of $0.45 per share. ( 2 )James G. Coulter and David Bonderman are officers and shareholders of TPG Advisors VI, Inc., a Delaware corporation ("Advisors VI" and, together with Messrs. Bonderman and Coulter, the "Reporting Persons"), which is the general partner of Armor TPG Holdings, L.P., a Delaware limited partnership ("Armor TPG"), which no longer holds the Common Stock. ( 3 )Because of the Reporting Persons' respective relationships to Armor TPG, the Reporting Persons may be deemed to have beneficially owned shares of Common Stock to the extent of the greater of their respective direct or indirect pecuniary interests in the profits or capital accounts of Armor TPG. Each Reporting Person disclaims beneficial ownership of any shares of Common Stock, except to the extent of such Reporting Person's pecuniary interest therein, if any. ( 4 )Pursuant to Rule 16a-1(a)(4) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), this filing shall not be deemed an admission that the Reporting Persons were, for purposes of Section 16 of the Exchange Act or otherwise, the beneficial owners of any shares of Common Stock in excess of their respective pecuniary interests.

Remarks: (5) The Reporting Persons are jointly filing this Form 4 pursuant to Rule 16a-3(j) under the Exchange Act. (6) Ronald Cami is signing on behalf of both Messrs. Bonderman and Coulter pursuant to authorization and designation letters dated July 1, 2013, which were previously filed with the Securities and Exchange Commission.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
