                                MASCO CORPORATION

                                 ($1 Par Value)


        All the shares of Common Stock being offered hereby (the "Shares") are
held by certain stockholders (the "Selling Stockholders") of Masco Corporation
("Masco" or the "Company").  Masco will not receive any of the proceeds from the
sale of the Shares.

        The Selling Stockholders (and their donees, distributees, pledgees and
personal representatives) may, from time to time, offer for sale and sell or
distribute the Shares to be offered by them hereby (a) in transactions executed
on the New York Stock Exchange or other exchanges on which the Shares may be
traded, (b) in negotiated transactions or (c) through other means.  Sales may be
effected at market prices prevailing at the time of sale or at such other prices
as may be negotiated by the Selling Stockholders.

        The Selling Stockholders may effect such transactions by selling Shares
to or through dealers, and such dealers may receive compensation in the form of
underwriting discounts, concessions or commissions from the Selling Stockholders
(which compensation, if any, is not expected to be in excess of customary
commissions).  The Selling Stockholders and any dealers that participate with
the Selling Stockholders in the distribution of Shares may be deemed to be
underwriters, and any commissions received by them and any profit on the resale
of Shares sold by them might be deemed to be underwriting discounts and
commissions under the Securities Act of 1933.

        Masco has agreed to indemnify the Selling Stockholders against certain
liabilities under the Securities Act of 1933.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
