                                MASCO CORPORATION
        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

A.    In the opinion of the Company, the accompanying unaudited condensed
      consolidated financial statements contain all adjustments, of a normal
      recurring nature, necessary to present fairly its financial position at
      September 30, 2004 and the results of operations for the three months and
      nine months ended September 30, 2004 and 2003 and changes in cash flows
      for the nine months ended September 30, 2004 and 2003. The condensed
      consolidated balance sheet at December 31, 2003 was derived from audited
      financial statements.

      Certain prior-year amounts have been reclassified to conform to the 2004
      presentation in the condensed consolidated financial statements. The
      results of operations related to discontinued operations have been
      reclassified and separately stated in the accompanying condensed
      consolidated statements of income for 2004 and 2003. In the Company's
      condensed consolidated balance sheet at September 30, 2004, the assets
      and liabilities of the businesses held for sale have been reclassified and
      separately stated. The assets and liabilities of the businesses held for
      sale have not been reclassified in the related accompanying condensed
      consolidated balance sheet as at December 31, 2003. In the Company's
      condensed consolidated statements of cash flows for the nine months ended
      September 30, 2004 and 2003, the cash flows of discontinued operations are
      not separately classified.

Note A - concluded:

      STOCK OPTIONS AND AWARDS. The Company implemented the fair value method of
      accounting for stock-based compensation prescribed by Statement of
      Financial Accounting Standards ("SFAS") No. 123, "Accounting for
      Stock-Based Compensation," effective January 1, 2003. The Company is using
      the prospective method, as defined by SFAS No. 148, "Accounting for
      Stock-Based Compensation - Transition and Disclosure - an amendment to
      SFAS No. 123," for determining stock-based compensation expense.
      Accordingly, options granted, modified or settled subsequent to January 1,
      2003 are accounted for using the fair value method, and options granted
      prior to January 1, 2003 continue to be accounted for using the intrinsic
      value method. In the first nine months of 2004, 4,941,000 option shares,
      including restoration option shares, were awarded. The following table
      illustrates the pro forma effect on net income and earnings per common
      share as if the fair value method were applied to all previously issued
      and outstanding stock options, in millions except per common share data:

  NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

B.    In the first quarter of 2004, the Company determined that several European
      businesses were not core to the Company's long-term growth strategy and,
      accordingly, embarked on a plan to sell such businesses. The dispositions
      are expected to be completed by March 31, 2005. In the first quarter of
      2004, the Company recognized a pre-tax charge of $64 million for those
      businesses that are expected to be divested at a loss.

      In the second and third quarters of 2004, the Company recognized
      additional charges of $44 million and $31 million, respectively,
      principally related to the remaining businesses held for sale. The Company
      has reduced its estimate of expected proceeds for these operations as a
      result of lower-than-expected operating results as well as a
      weaker-than-expected demand for the businesses that the Company is
      divesting. The Company expects aggregate net proceeds to approximate $250
      million.

      During the third quarter of 2004, in two separate transactions, the
      Company completed the sale of its Jung Pumpen and The Alvic Group
      businesses. Jung Pumpen manufactures a wide variety of submersible
      and drainage pumps and The Alvic Group manufactures kitchen cabinets;
      both of these businesses were included in discontinued operations. Total
      proceeds from the sale of these companies were $191 million, including
      cash of $185 million and notes receivable of $6 million. In the third
      quarter of 2004, the Company recognized a pre-tax, net gain on the
      disposition of these businesses of $108 million ($93 million or $.21 per
      common share, after tax). In the third quarter of 2003, the Company
      completed the sale of its Baldwin Hardware, Weiser Lock and Marvel Group
      divisions. In accordance with SFAS No. 144, "Accounting for the Impairment
      or Disposal of Long-Lived Assets," the Company has accounted for the 2004
      planned dispositions as well as operations which were sold in 2004 and
      2003 as discontinued operations.

      Selected financial information for discontinued operations (through the
      date of disposition) is as follows for the three months and nine months
      ended September 30, 2004 and 2003, in millions:

  NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

Note B - concluded:

      The charges for the impairment of assets held for sale for the three
      months and nine months ended September 30, 2004 are $31 million pre-tax
      ($31 million or $.07 per common share, after tax) and $139 million pre-tax
      ($151 million or $.33 per common share, after tax), respectively. The
      after-tax charge of $151 million for the nine months ended September 30,
      2004 includes $12 million of expensed deferred tax assets. The unusual
      relationship between income tax expense and income before income taxes
      (including the loss on disposition of businesses) in 2004 results
      primarily from the expected loss providing no current tax benefit in the
      countries where the loss is anticipated to be incurred and from the
      expensing of deferred tax assets of the discontinued operations which are
      no longer expected to be realized. In the first nine months of 2004, the
      Company also recorded approximately $6 million of severance and
      termination benefit expenses related to the discontinued operations,
      included in income before income taxes in the above table. The Company
      expects such costs to approximate $7 million in aggregate, the balance of
      which are expected to be recognized over the next six months.

      The impairment charge for assets held for sale primarily includes the
      write-down of goodwill of $61 million and fixed assets of $54 million for
      the nine months ended September 30, 2004.

      Total assets and liabilities held for sale consist primarily of the
      following at September 30, 2004 (after the impairment charges recorded in
      the first nine months of 2004), in millions:

      (B)   During the first nine months of 2004, the Company reclassified the
            goodwill related to businesses held for sale. The Company also
            recognized charges for those businesses expected to be divested at a
            loss; the charge included a write-down of goodwill of $63 million
            (including $36 million related to a business sold in the third
            quarter of 2004).

E.    The Company maintains investments in marketable securities (including
      marketable equity securities and bond funds) and a number of private
      equity funds, principally as part of its tax planning strategies, as any
      gains enhance the utilization of tax capital loss carryforwards. Included

      The Company has investments in over 70 different marketable equity
      securities and bond funds at September 30, 2004. The Company reviews
      industry analyst reports, key ratios and statistics, market analyses and
      other factors for each investment to determine if an unrealized loss is
      other than temporary. The unrealized loss at September 30, 2004 is
      primarily related to one marketable equity security, Furniture Brands
      International (NYSE: FBN) common stock (four million shares), which was
      received in June 2002 from the Company's investment in Furnishings
      International Inc. debt. Based on its review, the Company considers the
      unrealized loss related to this investment to be temporary. The market
      price of FBN during 2004 has been above and below the Company's cost basis
      of $30.25 per share. If the price remains significantly below the
      Company's cost basis, the Company may record an other-than-temporary asset
      impairment charge in the fourth quarter of 2004.

      The remaining $1 million or six percent of the Company's total unrealized
      loss in marketable equity securities at September 30, 2004 relates to 11
      marketable equity investments related to various industries. Based on its
      review, the Company believes that the cost basis of these investments is
      recoverable and that it has both the ability and intent to hold these
      investments until such time as the cost basis is recoverable.

  NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

Note F - concluded:

      The unrealized gain on marketable securities is reported net of income tax
      of $6 million and $15 million at September 30, 2004 and December 31, 2003,
      respectively.

      The minimum pension liability is reported net of income tax credit of $35
      million at both September 30, 2004 and December 31, 2003.

G.    The Company owns 64 percent of Hansgrohe AG. The minority interest of $74
      million and $70 million at September 30, 2004 and December 31, 2003,
      respectively, is recorded in the caption deferred income taxes and other
      liabilities on the Company's condensed consolidated balance sheets.

H.    In the first half of 2004, the Company retired the remaining $266 million
      of 6% notes due May 2004.

      On March 9, 2004, the Company issued $300 million of floating-rate notes
      due 2007, resulting in net proceeds of $299 million. The interest rate is
      calculated based on the three-month London Interbank Offered Rate
      ("LIBOR") plus .25%.

      In March 2004, the Company terminated two interest rate swaps relating to
      $850 million of fixed-rate debt. These swap agreements were accounted for
      as fair value hedges. The gain of approximately $45 million from the
      termination of these swaps is being amortized as a reduction of interest
      expense over the remaining term of the debt, through July 2012.

      In late March 2004, the Company entered into new interest rate swaps for
      the purpose of converting a portion of fixed-rate debt to variable-rate
      debt, which is expected to reduce interest expense, given current interest
      rates. The average variable interest rates are based on LIBOR plus a fixed
      adjustment factor. The average effective interest rate on the interest
      rate swaps is 2.275%. At September 30, 2004, the interest rate swap
      agreements covered a notional amount of $850 million of the Company's
      fixed-rate debt due July 15, 2012 with an interest rate of 5.875%. The
      interest rate swaps are considered 100 percent effective; therefore, the
      market valuation of $24 million at September 30, 2004 is recorded in other
      assets with a corresponding increase to long-term debt in the Company's
      condensed consolidated balance sheet at September 30, 2004.

(A)   Intra-segment sales were not material.

(B)   In accordance with SFAS No. 144 "Accounting for the Impairment or Disposal
      of Long-Lived Assets," the Company has accounted for the 2004 planned
      disposition of certain European businesses as discontinued operations.
      Accordingly, the assets and liabilities of those operations have been
      reclassified from the segments above. The reclassified assets, prior to
      any 2004 impairment charges, are as follows: Cabinets and Related Products
      - $242 million; Plumbing Products - $16 million; Decorative Architectural
      Products - $35 million; and Other Specialty Products - $107 million.

(C)   The Company recorded income regarding the litigation discussed in Note N
      related to the Company's subsidiary, Behr Process Corporation. Behr is
      included in the Decorative Architectural Products segment.

(D)   Due to the unexpected passing of the Company's President and Chief
      Operating Officer, certain benefits were accelerated and expensed in the
      first quarter of 2003, with an adjustment in the second quarter of 2003.

                                MASCO CORPORATION
  NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

Note L - concluded:

      During the third quarter of 2004, holders of 17,000 shares of the
      Company's convertible preferred stock converted all of their preferred
      stock to approximately 17 million shares of the Company's common stock.
      The convertible preferred shares carried substantially the same attributes
      as Company common stock and had been treated as if converted at a ratio of
      1 share of preferred stock to approximately 1,000 shares of common stock
      for basic and diluted earnings per common share computations.

      For both the three months and nine months ended September 30, 2004 and
      2003, approximately 24 million common shares related to the Zero Coupon
      Convertible Senior Notes due 2031 were not included in the computation of
      diluted earnings per common share since, at September 30, 2004 and 2003,
      they were not convertible according to their terms.

      Additionally, six million common shares for the nine months ended
      September 30, 2004, and three million and seven million common shares for
      the three months and nine months ended September 30, 2003, respectively,
      related to stock options were excluded from the computation of diluted
      earnings per common share due to their anti-dilutive effect, since the
      option exercise price was greater than the Company's average common stock
      price for these periods.

M.    In October 2004, the Emerging Issues Task Force ("EITF") Issue Summary No.
      04-8, "Accounting Issues Related to Certain Features of Contingently
      Convertible Debt and the Effect on Diluted Earnings Per Share" was
      approved by the Financial Accounting Standards Board. EITF No. 04-8 will
      require the Company to include 24 million shares in the calculation of
      diluted earnings per common share related to the Company's Zero Coupon
      Convertible Senior Notes due 2031 ("Notes"), with the add-back of the
      related interest expense to net income. EITF No. 04-8 will be effective
      beginning in the fourth quarter of 2004 and will require the restatement
      of previously reported diluted earnings per common share amounts.
      Currently, the shares are not included in the Company's calculation of
      diluted earnings per common share, since the Notes are not convertible
      according to their terms. In early November 2004, the Company amended the
      terms of the Notes to remove the Company's option to satisfy the purchase
      price with shares of Company common stock when purchasing the Notes at the
      option of the holder.

      In the first quarter of 2004, the Company adopted Financial Accounting
      Standards Board ("FASB") Interpretation No. 46 - Revised ("FIN 46R"),
      "Consolidation of Variable Interest Entities." FIN 46R requires that a
      company that is the primary beneficiary of a variable interest entity
      consolidate the assets, liabilities and results of operations of the
      variable interest entity in the company's consolidated financial
      statements. The adoption of FIN 46R did not have a material impact on the
      Company's condensed consolidated financial statements.

N.    LITIGATION. The Company is subject to lawsuits and pending or asserted
      claims with respect to matters generally arising in the ordinary course of
      business.

      As the Company reported in previous filings, late in the second half of
      2002, the Company and its subsidiary, Behr Process Corporation, agreed to
      two Settlements (the National Settlement and the Washington State
      Settlement) to resolve all class action lawsuits pending in the United
      States involving certain exterior wood coating products formerly
      manufactured by Behr.

      The deadlines for filing claims were September 2, 2003 for the National
      Settlement and January 17, 2004 for the Washington State Settlement.

      In the first quarter of 2004, the Company estimated the average cost per
      claim received related to the Washington State Settlement, and, as a
      result, estimated that the remaining unpaid claims and administration
      costs would be approximately $20 million less than estimated at December
      31, 2003. Accordingly, the Company reduced the litigation accrual
      (recognizing income) by $20 million in the first quarter of 2004.

      Proceeds from insurance carriers are recognized as income when Behr and
      its carriers agree on such amounts. The Company expects that the
      evaluation, processing and payment of claims for both the Washington State
      Settlement and the National Settlement will be completed by March 31,
      2005.

      Early in 2003, a suit was brought against the Company and a number of its
      insulation installation companies in the federal court in Atlanta,
      Georgia, alleging that certain practices violate provisions of federal and
      state antitrust laws. The plaintiff publicized the lawsuit with a press
      release and stated in that release that the Department of Justice was
      investigating the business practices of the Company's insulation
      installation companies. Although the Company was unaware of any
      investigation at that time, the Company was later advised that an
      investigation had been commenced but was subsequently closed without any
      enforcement action recommended. Two additional lawsuits were subsequently
      brought in Virginia making similar claims under the antitrust laws. Both
      of these lawsuits have since been dismissed without any payment or
      requirement for any change in business practices. During the second half
      of 2004, the same counsel who commenced the initial action in Atlanta
      filed six additional lawsuits on behalf of several of Masco's competitors
      in the insulation installation business. Recently, the plaintiffs
      dismissed five of these lawsuits and, represented by the same counsel,
      filed another action in the same federal court, seeking class
      representation for all independent insulation contractors against the
      Company, a number of its insulation installation companies and certain of
      their suppliers. Based upon the advice of its outside counsel, the Company
      believes that the conduct of the Company and its insulation installation
      companies, which has been the subject of any of the above-described
      lawsuits, has not violated any antitrust laws.

ITEM 2.              MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

      The Company reports its financial results in accordance with generally
accepted accounting principles ("GAAP") in the United States. However, the
Company believes that certain non-GAAP performance measures and ratios, used in
managing the business, may provide users of this financial information with
additional meaningful comparisons between current results and results in prior
periods. Non-GAAP financial measures and ratios should be viewed in addition to,
and not as an alternative for, the Company's reported results.

                                    ---------

      Net sales increased 12 percent and 16 percent, respectively, for the

      Net sales of Cabinets and Related Products increased 12 percent and 15
percent, respectively, in the three-month and nine-month periods ended September
30, 2004 compared with the same periods in 2003, primarily due to increased
sales volume of assembled cabinets largely through North American retail
distribution channels at major home centers and through the new construction
market in the United States, as well as a more favorable product mix.

      Net sales of Plumbing Products increased 12 percent and 16 percent,
respectively, in the three-month and nine-month periods ended September 30, 2004
compared with the same periods in 2003, primarily due to increased sales volume
in the retail markets in North America and Europe and in the new construction
markets in North America. In addition, the favorable impact of a weaker U.S.
dollar increased International sales included in this segment in 2004 compared
with 2003.

      Net sales of Installation and Other Services increased 15 percent and 16
percent, respectively, in the three-month and nine-month periods ended September
30, 2004 compared with the same periods in 2003, primarily due to increased
sales volume of non-insulation products, increased selling prices for insulation
products and increases in new residential construction and housing starts.

ITEM 2.               MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

      Net sales of Decorative Architectural Products increased 4 percent and 14
percent, respectively, in the three-month and nine-month periods ended September
30, 2004 compared with the same periods of 2003, primarily due to increased
sales volume of paints and stains as well as increased sales of decorative
hardware. Sales of paints and stains were strong for the nine months ended
September 30, 2004, with increases in the mid-teens compared to the same period
in 2003. Sales increases in the third quarter of 2004 were less robust
reflecting unusually strong sales in the third quarter of 2003 (which increased
over 2002 in excess of 20 percent) as a result of a very slow first half of 2003
due to adverse weather conditions. In addition, third quarter of 2004 sales were
negatively impacted by adverse weather, which affected sales in certain parts of
the country.

      Net sales of Other Specialty Products increased 20 percent and 21 percent,
respectively, in the three-month and nine-month periods ended September 30, 2004
compared with the same periods of 2003, primarily due to increased sales of
vinyl and fiberglass windows and doors in North America. In addition, the
favorable impact of a weaker U.S. dollar increased International sales included
in this segment in 2004 compared with 2003.

      Net sales from North American operations for the three-month and
nine-month periods ended September 30, 2004 increased 11 percent and 14 percent,
respectively, compared with the same periods of 2003, primarily due to the
reasons discussed above. Net sales from International operations for the
three-month and nine-month periods ended September 30, 2004 increased 20 percent
and 23 percent, respectively, compared with the same periods of 2003, primarily
due to increased sales of cabinets and plumbing products, benefitting from
additional penetration of the retail markets, as well as a weaker U.S. dollar,
principally against the Euro, which increased International sales by
approximately 11 percent and 12 percent for the three-month and nine-month
periods ended September 30, 2004.

                                OPERATING MARGINS
                                -----------------

      The Company's gross profit margins increased to 31.2 percent for both the
three-month and nine-month periods ended September 30, 2004 from 31.0 percent
and 30.6 percent, respectively, for the comparable periods in 2003. The increase
in gross profit margins reflects increased sales volume, offset in part by
increased sales in segments which have somewhat lower margins as well as
increased material costs. In addition, operating results for the three-month and
nine-month periods ended September 30, 2003 were reduced by non-cash, pre-tax
charges of $42 million and $59 million relating to two United Kingdom business
units, one in the Decorative Architectural Products segment and the other in the
Plumbing Products segment. Offsetting the charges related to the United Kingdom
business units discussed above, operating profit for the three-month and
nine-month periods ended September 30, 2003 also benefited from $58 million and
$71 million, respectively, of Behr litigation income. Operating profit for the
three-month and nine-month periods ended September 30, 2004 includes $2 million
and $30 million, respectively, of Behr litigation income.

      The Company's operating profit margins, as reported, were 15.5 percent and
15.0 percent, respectively, for the three-month and nine-month periods ended
September 30, 2004 compared with 16.8 percent and 14.7 percent for the same
periods of 2003. The Company's operating profit margins, excluding the Behr
litigation income of $2 million and $30 million for the three-month and
nine-month periods ended September 30, 2004, respectively, and $58 million and
$71 million for the three-month and nine-month periods ended September 30, 2003,
respectively, and the accelerated benefit expense of $16 million for the
nine-month period ended September 30, 2003, were 15.4 percent and 14.7 percent
for the three-month and nine-month periods ended September 30, 2004,
respectively, and 14.7 percent and 14.0 percent for the three-month and
nine-month periods ended September 30, 2003, respectively. The Company's
operating profit margins, reflecting the adjustments discussed above, increased
for the three-month and nine-month periods ended September 30, 2004 compared
with the same periods of 2003, principally due to the reasons discussed.

      Selling, general and administrative expenses as a percentage of sales were
15.8 percent and 16.5 percent, respectively, for the three-month and nine-month
periods ended September 30, 2004 and 16.3 percent and 16.8 percent,
respectively, for the comparable periods of the prior year. Selling, general and
administrative expenses for the three-month and nine-month periods ended
September 30, 2004 were positively impacted by lower promotion and advertising
costs compared with the same period in 2003. This improvement was partially
offset by increased costs and expenses associated with complying with the new
requirements of the Sarbanes-Oxley Legislation. Selling, general and
administrative expenses for the nine-month period ended September 30, 2003
include $16 million of accelerated benefit expense related to the unexpected
passing of the Company's President and Chief Operating Officer. Excluding the
accelerated benefit expense, selling, general and administrative expense for the
nine-month period ended September 30, 2003 would have been 16.6 percent.

ITEM 2.              MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

      Operating profit margins for the Cabinets and Related Products segment for
the three-month and nine-month periods ended September 30, 2004 were 17.5
percent and 16.3 percent, respectively, compared with 16.0 percent and 14.9
percent for the same periods in 2003, and reflect the positive impact of higher
sales volume and a more favorable product mix offset in part by increased costs
related to wood and particleboard materials.

      Operating profit margins for the Plumbing Products segment were 13.0
percent and 13.7 percent, respectively, for the three-month and nine-month
periods ended September 30, 2004 compared with 13.9 percent for both of the same
periods of 2003, primarily due to an increase in sales of lower-margin products
included in this segment as well as increased material costs offset in part by
increased sales volume. As previously discussed, operating profit in the first
nine months of 2003 for this segment was negatively affected by a non-cash,
pre-tax charge of $4 million relating to a United Kingdom business unit where an
employee had circumvented internal controls to misstate operating profit in 2002
and 2003.

      Operating profit margins for the Installation and Other Services segment
were 14.0 percent and 13.2 percent, respectively, for the three-month and
nine-month periods ended September 30, 2004 compared with 17.1 percent and 15.5
percent for the same periods of 2003. The operating profit margin decline in
this segment is primarily attributable to increased material costs as well as an
increase in sales of generally lower-margin, non-insulation products.
Historically, the Company has generally been able to increase its selling prices
to reflect certain material cost increases. Typically, the benefits of such
selling price increases are reflected in subsequent periods, as there is a time
lag as a result of existing contractual obligations.

      Within the Installation and Other Services segment, the availability of
fiberglass insulation to support the Company's installation and distribution
activities has been constrained in 2004. The high level of demand for fiberglass
insulation as a result of the strength of the new residential construction
market has outpaced the industry's capacity to produce additional product. The
Company believes that these conditions will persist over the balance of 2004 and
is working with its diverse supplier base to secure as much material as
possible. At the current time, the Company does not believe that this material
shortage will have a significant impact on its operations.

      Operating profit margins for the Decorative Architectural Products segment
were 23.6 percent and 21.3 percent, respectively, for the three-month and
nine-month periods ended September 30, 2004 compared with 12.4 percent and 14.7
percent for the same periods of 2003. The margin improvement includes the effect
of increased sales volume of paints and stains and decorative hardware offset in
part by increased material and promotion costs. As previously discussed,
operating profit in this segment for the three-month and nine-month periods
ended September 30, 2003 was negatively affected by non-cash, pre-tax charges of
$35 million and $55 million, respectively, related to a United Kingdom business
unit. The charge resulted from a business system implementation failure which
allowed former management of the business to circumvent internal controls and
artificially inflate the unit's operating profit in years prior to 2003.

ITEM 2.              MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

      Operating profit margins for the Other Specialty Products segment were
23.1 percent and 20.2 percent, respectively, for the three-month and nine-month
periods ended September 30, 2004 compared with 20.3 percent and 18.1 percent for
the same periods of 2003. The margin improvement is primarily attributable to
increased sales of vinyl and fiberglass windows and doors.

                           OTHER INCOME (EXPENSE), NET
                           ---------------------------

      Other, net, for the three-month and nine-month periods ended September 30,
2004 includes $(2) million and $23 million, respectively, of realized (losses)
gains, net, from the sale of marketable securities, dividend income of $8
million and $22 million, respectively, and $11 million and $29 million,
respectively, of income, net, regarding other investments. Other items, net for
the three-month and nine-month periods ended September 30, 2004 includes $(1)
million and $11 million, respectively, of currency transaction (losses) gains.
Other items, net for the nine-month period ended September 30, 2004 also
includes a $5 million gain from the sale of non-operating assets.

      Other, net, for the three-month and nine-month periods ended September 30,
2003 includes $7 million and $24 million, respectively, of realized gains, net,
from the sale of marketable securities, dividend income of $6 million and $19
million, respectively, and $6 million and $9 million, respectively, of income,
net, regarding other investments. Other, net for the three-month and nine-month
periods ended September 30, 2003 includes a $9 million impairment charge for the
write-down of an investment in a private equity fund. Other, net for the
nine-month period ended September 30, 2003 also includes a $5 million gain from
the sale of the Company's equity investment in Emco Limited.

      Interest expense for the three-month and nine-month periods ended
September 30, 2004 decreased $12 million and $41 million, respectively, to $55
million and $160 million, compared with interest expense of $67 million and $201
million, respectively, for the same periods of 2003 primarily due to debt
repurchases as well as the effect of the interest rate swap agreements that
converted a certain amount of fixed-rate debt to lower variable-rate debt.

                                MASCO CORPORATION

ITEM 2.              MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

         INCOME AND EARNINGS PER COMMON SHARE FROM CONTINUING OPERATIONS
         ---------------------------------------------------------------

      Income from continuing operations for the three-month and nine-month
periods ended September 30, 2004 was $289 million and $824 million,
respectively, compared with $258 million and $636 million, respectively, for the
comparable periods of 2003. Diluted earnings per common share from continuing
operations for the three-month and nine-month periods ended September 30, 2004
were $.64 and $1.81 per common share, respectively, compared with $.53 and $1.28
per common share, respectively, for the comparable periods of 2003. The
Company's effective tax rate was 36.3 percent and 36.1 percent, respectively,
for the three-month and nine-month periods ended September 30, 2004, compared
with 37.0 percent and 35.7 percent, respectively, for the same periods in 2003.
The Company estimates that its effective tax rate should approximate 36 percent
for 2004. However, because the American Jobs Creation Act of 2004, recently
signed into law in the fourth quarter of 2004, contains changes that impact the
U.S. tax on the distribution of accumulated foreign earnings, the Company may
consider making a significant dividend distribution from its foreign
subsidiaries. This possible dividend, along with the potential effect of other
new provisions, may impact the Company's effective tax rate in the fourth
quarter of 2004 or in 2005. The increase in the tax rate for the nine-month
period is principally due to a change in the mix of foreign earnings in
countries with higher tax rates.

                           OTHER FINANCIAL INFORMATION
                           ---------------------------

      The Company's current ratio was 2.1 to 1 at September 30, 2004 compared
with 1.8 to 1 at December 31, 2003.

      For the nine months ended September 30, 2004, cash of $973 million was
provided by operating activities. Cash used for financing activities was $964
million, including $266 million for the retirement of notes, $227 million for
cash dividends paid, $777 million for the acquisition and retirement of Company
common stock in open-market transactions, $40 million for the acquisition of
Company common stock for the Company's long-term stock incentive award plan and
$43 million for a net decrease in bank debt. Cash provided by financing
activities included $299 million from the issuance of notes (net of issuance
costs), $55 million from interest rate swap transactions and $35 million from
the issuance of Company common stock, primarily for the exercise of stock
options. Cash provided by investing activities was $204 million and primarily
included $207 million from the net sales of marketable securities and other
investments and $178 million from the disposition of businesses (net of cash
disposed). Cash used for investing activities primarily included $188 million
for capital expenditures. Cash at businesses held for sale was $38 million at
September 30, 2004.

      In the first half of 2004, the Company retired the remaining $266 million
of 6% notes due May 2004.

      The Company is subject to lawsuits and claims pending or asserted with
respect to matters generally arising in the ordinary course of business. Note N
to the Condensed Consolidated Financial Statements discusses specific claims
pending against the Company.

      The Company believes that its present cash balance, its cash flows from
operations and, to the extent necessary, bank borrowings and future financial
market activities, are sufficient to fund its working capital and other
investment needs.

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

                             OUTLOOK FOR THE COMPANY
                             -----------------------

      The Company continues to experience better than expected sales performance
as sales of assembled cabinets, paints and stains, installation services and
windows have continued strong in the first nine months of 2004. The Company also
continues to experience increases in certain operating expenses, particularly
for certain material costs, as well as costs associated with complying with the
new requirements of the Sarbanes-Oxley Legislation. Based on current business
trends and the record sales and earnings achieved in the first nine months of
2004, the Company expects to achieve record sales and earnings for the full year
of 2004.

                           FORWARD-LOOKING STATEMENTS
                           --------------------------

      Certain sections of this Quarterly Report contain statements reflecting
the Company's views about its future performance and constitute "forward-looking
statements" under the Private Securities Litigation Reform Act of 1995. These
views involve risks and uncertainties that are difficult to predict and,
accordingly, the Company's actual results may differ materially from the results
discussed in such forward-looking statements. Readers should consider that
various factors, including changes in general economic conditions, competitive
market conditions and pricing pressures, relationships with key customers,
industry consolidation of retailers, wholesalers and builders, shifts in
distribution, the influence of e-commerce and other factors discussed in the
Company's Annual Report on Form 10-K and its other filings with the Securities
and Exchange Commission, may affect the Company's performance. The Company
undertakes no obligation to update publicly any forward-looking statements as a
result of new information, future events or otherwise.

      The Company is in the process of evaluating its internal control system
over financial reporting in accordance with the requirements of Section 404 of
the Sarbanes-Oxley Act of 2002. Because of the Company's historical growth
through acquisition and its decentralized organizational structure with over 50
reporting units and over 600 operating locations worldwide, the Company
estimates that it has well in excess of 20,000 key controls over financial
reporting. As part of this initiative, the Company has invested a substantial
amount of time and resources in documenting and testing its system of internal
control. During the course of this comprehensive process, the Company and its
independent auditors have identified control deficiencies. The Company has
corrected a number and is remediating others of these control deficiencies.
However, there can be no assurance that one or more deficiencies will not
constitute what the Company or its independent auditors conclude is a material
weakness in internal control over financial reporting. Additionally, there can
be no assurance in light of the Company's decentralization, the number of its
operating units and magnitude of the overall initiative, that the Company will
be able to complete the process in time to allow its independent auditors to
finish their assessment and issue their audit report on a timely basis. The
Company believes, however, based on its current knowledge, that its
documentation, testing and final assessment will be completed on a timely basis.

ITEM 2.              MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

      The Company owns four million shares of Furniture Brands International
common stock, which was received in June 2002 from the Company's investment in
Furnishings International Inc. debt. The market price during 2004 has been above
and below the Company's cost basis. If the price remains significantly below the
Company's cost basis, the Company may record an other-than-temporary asset
impairment charge in the fourth quarter of 2004.

      At September 30, 2004, the Company has a $1.25 billion, 5-year revolving
credit agreement (due November 2005) and a $750 million, 364-day revolving
credit agreement (due November 2004) which are currently being renegotiated. The
Company expects to finalize a new 5-year, $2 billion revolving credit agreement
in early November 2004, which will replace both of the existing agreements.

ITEM 4. CONTROLS AND PROCEDURES

      a.    Evaluation of Disclosure Controls and Procedures.

            The Company's principal executive officer and principal financial
            officer have concluded, based on an evaluation of the Company's
            "disclosure controls and procedures" (as defined in the Securities
            Exchange Act of 1934 Rules 13a-15(e) or 15d-15(e)) as required by
            paragraph (b) of Exchange Act Rules 13a-15 or 15d-15, that, as of
            September 30, 2004, the Company's disclosure controls and procedures
            were effective and designed to ensure that information required to
            be disclosed by the Company in the reports it files under the
            Exchange Act is recorded, processed, summarized and reported within
            the time periods specified in the Securities and Exchange
            Commission's rules and forms.

      b.    Changes in Internal Control Over Financial Reporting.

            There has been no change in the Company's internal control over
            financial reporting identified in connection with the evaluation
            required by paragraph (d) of Exchange Rules 13a-15 or 15d-15 that
            occurred during the Company's last fiscal quarter (the Company's
            fourth fiscal quarter in the case of an annual report) that has
            materially affected, or is reasonably likely to materially affect,
            the Company's internal control over financial reporting.
