ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

     On February 10, 2006, Masco Corporation and Masco Europe s.a r.l., as
borrowers, entered into Amendment No. 1 to 5-Year Revolving Credit Agreement
with the banks party thereto and JPMorgan Chase Bank, N.A., as administrative
agent. The Amendment modifies the terms of Masco's U.S. $2 billion 5-year
Revolving Credit Agreement, dated as of November 5, 2004 among Masco and Masco
Europe, as borrowers, and certain banks party thereto, as lenders, J.P. Morgan
Securities Inc. and Citigroup Global Markets, Inc., as Joint Lead Arrangers and
Joint Book Runners and Citibank, N.A., as Syndication Agent, Sumitomo Mitsui
Banking Corporation, as Documentation Agent, and Bank One, NA (Main Office
Chicago) (which merged with JPMorgan Chase Bank, N.A.), as Administrative Agent.

     The Amendment modifies the minimum consolidated net worth covenant so that
the "Consolidated Net Worth" of Masco (as defined in the Agreement) shall not be
less than 70% of the Consolidated Net Worth of Masco for the preceding fiscal
year. The Amendment also extends the termination date (originally November 5,
2009) until February 10, 2011 and permits Masco to seek annually a one-year
extension of the termination date, provided any such request is made within a
45-day period before the anniversary of the effective date of the Amendment.

     Richard A. Manoogian, Chairman and Chief Executive Officer of Masco, is a
director of JPMorgan Chase & Co., an affiliate of JPMorgan Chase Bank, N.A.
Another affiliate J.P. Morgan Trust Company, National Association acts as
trustee under Masco's indentures. In the ordinary course of their respective
businesses, certain of the participants in the credit facility or their
affiliates have performed investment banking, commercial banking and other
financial services for Masco and its affiliates, including acting as lenders
under various loan facilities and as underwriters in offerings of Masco
securities.

     A copy of the Amendment is attached hereto as Exhibit 4 and incorporated
herein by reference.
