For Executing Forms 3, 4 and 5





      I appoint each of Barry J. Silverman, Carolyn M. Christian, and John G.

Sznewajs,  signing singly, my attorney-in-fact to:



(1)  execute and file with the Securities and Exchange Commission on my

       behalf Forms 3, 4 or 5 as required by Section 16(a) of the Securities

       Exchange Act of 1934 and the rules thereunder, and any amendments

thereto; and



(2)  do anything in connection with the foregoing which such

       attorney-in-fact may deem legally required by me or in my best

interest.



      I grant to each such attorney-in-fact full power and authority to do and perform

any and every act and thing whatsoever requisite, necessary or proper to be done in the

exercise of any of the rights and powers herein granted, as fully to all intents and

purposes as I could do if personally present, with full power of substitution, hereby

ratifying and confirming all that such attorney-in-fact shall lawfully do or cause to be

done by virtue of this Power of Attorney and the rights and powers herein granted.



      I acknowledge that this Power of Attorney is granted by me individually and as a

Director, Trustee or Co-Trustee of any charitable organization, foundation or trust

holding shares of Masco Corporation and which is subject to the reporting requirements

of Section 16(a) of the Securities Exchange Act of 1934.



      I acknowledge that the foregoing attorneys-in-fact, in serving in such capacity at

my request, are not assuming, nor is Masco Corporation assuming, any of my

responsibilities to comply with Section 16 of the Securities Exchange Act of 1934.



      This Power of Attorney supersedes any Power of Attorney executed by me,

which is hereby revoked.  This Power of Attorney shall remain in effect until I am no

longer required to file Forms 3, 4, and 5 with respect to my holdings of and transactions

in securities issued by Masco Corporation, unless earlier revoked in writing by me.



      This Power of Attorney is executed on December 9, 2008.
