ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

      On October 27, 2005, the Board of Directors approved the amendment of the 
Masco Corporation 1997 Non-Employee Directors Stock Incentive Plan (the "1997 
Plan") and existing options to non-employee directors under the 1997 Plan and 
the Masco Corporation 1991 Long Term Stock Incentive Plan (the "1991 Plan") to 
provide that upon termination of service as a director (other than as a result 
of death, disability or retirement due to age), all then exercisable options 
will remain exercisable beyond the three-month period currently provided until 
the later of (i) the 15th day of the third month following the date at which the
option would otherwise have terminated in connection with the termination of 
service, or (ii) December 31 of the calendar year in which the option would 
otherwise have terminated in connection with the termination of service. Future 
options granted to non-employee directors will provide that upon termination of
service as a director (other than as a result of death, disability or
retirement due to age), all then exercisable options will remain exercisable 
until the earlier of the expiration of the original option term or one year 
after death. Upon termination of service as a director by reason of disability, 
all options will become and remain exercisable until the earlier of the 
expiration of the original option term or one year after death. Provisions in 
the 1997 Plan currently provide that upon termination of a director's service 
(i) as a result of death, options become and remain exercisable for a one-year 
period after death, and (ii) as a result of retirement due to age, options 
continue to become exercisable and remain exercisable until the earlier of the 
expiration of the original option term or one year after death. These provisions
remain unchanged by the amendments. The 1997 Plan and options to non-employee 
directors under the 1997 Plan and the 1991 Plan will also be amended to
remove the Company's right to require the repayment of the after-tax value of
any installment of an option that became exercisable and was exercised within
the two-year period preceding a director's termination of service.

     Outstanding awards to all participants under the 1991 Plan will be amended 
to conform certain provisions to those in the Masco Corporation 2005 Long Term 
Stock Incentive Plan (the "2005 Plan"). Specifically, conforming amendments will
be made to provisions in outstanding options relating to voluntary termination 
of employment and termination of employment by reason of disability. The 
definition of "Change in Control" in the 1991 Plan, the 1997 Plan and all 
outstanding awards of options and restricted stock under such plans will also be
amended to conform to the 2005 Plan.
