ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.
- ---------------------------------------------

         On June 30, 1999, Armstrong World Industries, Inc., a Pennsylvania
Corporation ("Armstrong"), sold 65% of its ownership in Armstrong Industrial
Specialties, Inc. ("AISI"), its gasket products subsidiary, to a group of
investors including Citicorp Venture Capital Ltd. and the management of AISI for
a cash purchase price of approximately $36.1 million. The sale will result in a
pretax and an after tax gain in Armstrong's second quarter of approximately
$8.3 million, or $0.21 per share. The pretax and after tax gains are the same
due to the realization of capital loss carryforwards.

         AISI is a leading manufacturer of soft gasket materials and specialty
papers. AISI will be renamed Interface Solutions, Inc. ("IT"), and it is
anticipated that the company will remain headquartered in Lancaster,
Pennsylvania with its current management team. AISI reported sales of
approximately $106.5 million in 1998 which included approximately $39.5 million
of sales to another Armstrong business unit.

         Under the terms of the Agreement and Plan of Merger the ("Agreement"),
Armstrong will continue to purchase felt products used in the manufacturing of
sheet vinyl flooring from IT for an initial term of eight years. The Agreement
also calls for quarterly adjustments to raw material prices, up and down, based
upon changing market prices. Armstrong can purchase felt products from another
supplier if IT's prices are more than 10% higher than another supplier's prices.
While the Agreement requires Armstrong and IT to cooperate in product
reformulation and new product development, Armstrong is free to seek
alternatives to felt products.

         Armstrong plans to use the cash proceeds from the sale to reduce its
outstanding debt.
