Explanation of Responses:

1. On August 10, 2009, pursuant to the terms of a Purchase and Sale Agreement (the "PSA"), the reporting person agreed to sell 7,000,000 shares and, concurrently with the closing of such sale, enter into a prepaid forward sale contract with TPG Partners V, L.P. and TPG Partners VI, L.P. (collectively, "TPG").

2. The forward sale contract obligates the reporting person to deliver to TPG cash (or elect to deliver 1,039,777 shares) on the settlement date of the forward sale contract. The settlement date is the third currency business day following the 20th scheduled trading day beginning on November 4, 2013. In exchange for assuming this obligation, the reporting person will receive $23,197,425 (determined by multiplying 1,039,777 shares by the per share sale price of $22.31 under the PSA).

3. The reporting person will pledge 1,039,777 shares of AWI common stock (the "Pledged Shares") to secure its obligations under the forward sale contract. While the reporting person will retain dividend and voting rights in the Pledged Shares during the term of the pledge, the reporting person is obligated to pay TPG dividends received on 1,039,777 shares underlying the forward sale contract.
