Section 8 – Other Events.

Item 8.01 Other Events.

The 2008 Directors Stock Unit Plan (the “2008 Plan”), provides for the grant of stock units to non-employee directors of the Company as payment for a portion of the director’s annual retainer.

On October 29, 2010, in accordance with the 2008 Plan, Armstrong World Industries, Inc. (the “Company”) granted to each of Tao Huang, Michael F. Johnston, Larry S. McWilliams, Richard E. Wenz and Bettina M. Whyte a 2010 annual award of 2,042 stock units. The Company also granted to each of Stan A. Askren, James J. Gaffney, James J. O’Connor and John J. Roberts a 2010 award of 1,532 stock units. The differences in the number of shares granted to directors reflects, as allowed by the 2008 Plan, a pro-ration based on the period of time served by the directors between their election to the Board of Directors and the next annual meeting of the shareholders; in the case of the directors receiving 1,532 units, the grants supplement grants received in October 2009. The Board also awarded to James J. O’Connor, the Chairman of the Board, an additional 1,278 share units in respect of his service as Chairman for the period November 2010 until the next annual meeting of the shareholders.

All such share units vest, contingent upon the director’s continued service as a director of the Company, on the day before the 2011 annual meeting of shareholders, currently scheduled for June 23, 2011 or, if earlier: (i) the death or total and permanent disability of the director; or (ii) the date of any change-in-control event, as defined under the 2008 Plan, and are subject to other terms specified in the 2008 Plan. The 2008 Plan is incorporated by reference from the 2008 Annual Report on Form 10-K, wherein it appeared as Exhibit 10.27. The Unit Agreement form granting the annual grant is incorporated by reference from the Quarterly Report on Form 10-Q for the quarter ended September 30, 2009, wherein it appeared as Exhibit 10.27.

In connection with amendments to the 2008 Plan, effective November 30, 2010, annual grants will be awarded to non-employee directors each year on the first business day following the first regular Board meeting following the annual meeting of shareholders. The 2008 Plan, as amended, is incorporated by reference from the Current Report on Form 8-K dated August 5, 2010, wherein it appeared as Exhibit 99.3.
