                                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 as at
      March 31, 2004 and the results of operations and changes in cash flows for
      the three months ended March 31, 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 as at March 31, 2004, the assets and
      liabilities of these businesses held for sale have been reclassified and
      separately stated. The assets and liabilities of these businesses held for
      sale as at December 31, 2003 have not been reclassified in the
      related accompanying condensed consolidated balance sheet. In the
      Company's condensed consolidated statements of cash flows for the three
      months ended March 31, 2004 and 2003, the cash flows of discontinued
      operations are not separately classified.

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

Note A - concluded:

      STOCK OPTIONS AND AWARDS. The Company has 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 quarter of 2004, 155,000 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 and unvested stock options, in millions except per common
      share data:

B.    In the first quarter of 2004, the Company determined that several European
      businesses are not core to the Company's long-term growth strategy and,
      accordingly, has embarked on a plan to sell these businesses. The
      dispositions are expected to be completed within the next twelve months.
      In the first quarter of 2004, the Company recognized a charge for those
      businesses that are expected to be divested at a loss. Any gains resulting
      from the disposition of individual businesses, which are expected later
      this year, will be recognized as such transactions are completed and are
      expected to substantially offset the charge recognized in the first
      quarter of 2004. 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 2003 dispositions
      and the 2004 planned dispositions as discontinued operations.

      The after-tax charge for the impairment of assets held for sale is $76
      million or $.16 per common share. 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 quarter of 2004, the Company also recorded
      approximately $2 million of severance and termination benefit expenses,
      included in income before income taxes from discontinued operations. The
      Company expects such costs to approximate $10 million in aggregate, which
      will be recognized over the next twelve months.

      The impairment of assets held for sale primarily includes the
      write-downs of goodwill of $29 million and fixed assets of $35 million.

      Total assets and liabilities held for sale consist primarily of the
      following at March 31, 2004 (after the impairment charge recorded in the
      first quarter of 2004), in millions:

      (A)   During the first quarter of 2004, the Company reclassified the
            goodwill related to businesses held for sale. In late March 2004,
            the Company recognized a charge for those businesses expected to be
            divested at a loss; the charge included a write-down of goodwill of
            $29 million.

      (B)   Other principally includes foreign currency translation adjustments,
            reclassifications and other purchase price adjustments related to
            the finalization of certain purchase price allocations.

      Other indefinite-lived intangible assets include registered trademarks of
      $255 million at March 31, 2004. The carrying value of the Company's
      definite-lived intangible assets is $83 million at March 31, 2004 (net of
      accumulated amortization of $50 million) and principally includes customer
      relationships and non-compete agreements.

D.    Depreciation and amortization expense is $59 million and $55 million for
      the three months ended March 31, 2004 and 2003, respectively.

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
      in other long-term assets are the following financial investments, in
      millions:

      Unrealized gain on marketable securities is reported net of income tax of
      $21 million and $15 million at March 31, 2004 and December 31, 2003,
      respectively.

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

G.    The Company owns 64 percent of Hansgrohe AG. The minority interest of $72
      million and $70 million at March 31, 2004 and December 31, 2003,
      respectively, is recorded in the balance sheet caption deferred income
      taxes and other liabilities on the Company's condensed consolidated
      balance sheets.

H.    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 floating 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 March 31, 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%.

      For both the three months ended March 31, 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 March 31, 2004 and 2003, they were not convertible
      according to their terms.

      Additionally, 3.1 million common shares and 23.2 million common shares for
      the three months ended March 31, 2004 and 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 for those shares was greater than the Company's average common stock
      price during such periods.

      In the first quarter of 2004, the Company repurchased and retired
      approximately 15 million shares of Company common stock, at a cost
      aggregating approximately $422 million. At March 31, 2004, the Company has
      approximately 33 million common shares remaining under the December 2003
      Board of Directors repurchase authorization.

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

M.    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 deadline for claims in the Washington State Settlement was January 17,
      2004. In the first quarter of 2004, the Company paid out approximately $2
      million for claims and received insurance reimbursements aggregating
      approximately $1 million; the insurance reimbursements were recognized as
      income. The Company estimated the average cost per claim received and, as
      a result, estimated that the remaining unpaid claims and administration
      costs related to the Washington State Settlement will approximate $30
      million at March 31, 2004. Accordingly, the Company reduced the litigation
      accrual (recognized income) by approximately $20 million in the first
      quarter of 2004.

      The remaining accrual for the National Settlement at March 31, 2004
      related to claims and administrative costs is approximately $10 million.

      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 September 30, 2004.

      STOCK PRICE GUARANTEES. Stock price guarantees as of March 31, 2004 are

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

      Net sales for the three months ended March 31, 2004 increased 19 percent
from the comparable period in 2003.

      The following table reconciles reported net sales to net sales excluding
acquisitions and the effect of currency translation, in millions:

                                                     =========      =========


      Net sales of Cabinets and Related Products increased 18 percent in the
first quarter of 2004 compared with 2003, primarily due to increased sales
volume of assembled cabinets and a more favorable product mix. Results were
positively impacted by the continuing strength of new construction markets and
retail distribution channels.

      Net sales of Plumbing Products increased 19 percent in the first quarter
of 2004 compared with 2003, primarily due to a more favorable product mix as
well as the favorable impact of a weaker U.S. dollar which increased
International net sales included in this segment.

      Net sales of Installation and Other Services increased 16 percent in the
first quarter of 2004 compared with 2003, primarily due to increased sales of
non-insulation products in 2004 and as a result of increased new construction
and housing starts. Adverse weather conditions in the first quarter of 2003
negatively impacted 2003 results.

      Net sales of Decorative Architectural Products increased 28 percent in the
first quarter of 2004 compared with 2003, primarily due to increased sales of
paints and stains and certain decorative hardware.

      Net sales of Other Specialty Products increased 20 percent in the first
quarter of 2004 compared with 2003, primarily due to a change in product mix,
including increased sales of fiberglass doors and windows as well as increased
sales of vinyl windows. In addition, the favorable impact of a weaker U.S.
dollar increased International net sales included in this segment.

                                MASCO CORPORATION

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

      Net sales from North American and International operations for the first
quarter of 2004 increased 18 percent and 26 percent, respectively, compared
with the first quarter of 2003. In the first quarter of 2004, International
sales continued to be positively affected by a weaker U.S. dollar, principally
against the Euro, which increased International net sales by approximately 17
percent.

                                OPERATING MARGINS

      The Company's gross profit margins were 30.3 percent for the first quarter
of 2004 compared with 30.1 percent for the comparable period in 2003. Gross
profit margins in the first quarter of 2004 were adversely impacted by
anticipated increases in certain operating expenses, including increased
material costs, which offset the positive impact of higher sales volume.
Selling, general and administrative expenses as a percentage of sales were 17.3
percent for the first quarter of 2004 and 17.9 percent for the comparable period
of the prior year. Selling, general and administrative expenses in the first
quarter of 2003 included $21 million of accelerated benefit expense relating to
the unexpected passing of the Company's President and Chief Operating Officer.
Selling, general and administrative expenses for the first quarter of 2004
include the effect of higher promotion costs as well as costs and expenses
associated with complying with the new requirements of the Sarbanes-Oxley
legislation. Operating income in the first quarters of 2004 and 2003 also
benefited from $21 million and $13 million, respectively, of income regarding
the Behr litigation settlement.

      Operating profit margins for the Cabinets and Related Products segment for
the first quarter of 2004 were 14.0 percent compared with 12.5 percent in the
first quarter of 2003, and reflect the positive impact of higher sales volume
and a more favorable product mix.

      Operating profit margins for the Plumbing Products segment were 13.0
percent in the first quarter of 2004 compared with 13.8 percent in the first
quarter of 2003, primarily due to relatively higher International sales with
lower margins, as well as increased material costs.

      Operating profit margins for the Installation and Other Services segment
were 12.9 percent in the first quarter of 2004 compared with 14.2 percent in the
first quarter of 2003. The operating margin decline in this segment is primarily
attributable to increased sales of generally lower-margin non-insulation
products as well as increased material costs.

      Within the Installation and Other Services segment, the availability of
fiberglass insulation to support the Company's installation and distribution
activities has become constrained in recent months. The high level of demand for
fiberglass insulation as a result of a strong new construction market has
outpaced the industry's capacity to produce additional product. The Company
believes that these conditions will persist over the remainder 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 17.3 percent for the first quarter of 2004 compared with 19.1 percent in
the first quarter of 2003. The positive impact of higher sales volume of paints
and stains was offset by increased material and display and advertising costs of
certain decorative hardware businesses.

      Operating profit margins for the Other Specialty Products segment were
15.6 percent in the first quarter of 2004 compared with 15.4 percent in the
first quarter of 2003.

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

      The Company's operating profit margins, after general corporate expense,
were 13.8 percent for the first quarter of 2004 compared with 12.8 percent for
the first quarter of 2003. Excluding the income regarding litigation settlement
of $21 million and $13 million in 2004 and 2003, respectively, and the
accelerated benefit expense of $21 million in 2003, operating profit margins
were 13.0 percent for the first quarter of 2004 compared with 13.1 percent for
the first quarter of 2003.

                           OTHER INCOME (EXPENSE), NET

      Other, net for the first quarter of 2004 includes $16 million of net
realized gains from the sale of marketable securities, dividend income of $7
million and $13 million of income, net regarding other investments.

      Other, net for the first quarter of 2003 includes $8 million of realized
gains from the sale of marketable securities, dividend income of $7 million and
$1 million of expense, net regarding other investments.

      Interest expense for the first quarter of 2004 decreased $14 million to
$53 million compared with $67 million in the first quarter 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.

         INCOME AND EARNINGS PER COMMON SHARE FROM CONTINUING OPERATIONS

      Income and diluted earnings per common share from continuing operations
for the first quarter of 2004 were $241 million and $.52 per common share
compared with $158 million and $.30 per common share for the comparable period
of 2003. The Company's effective tax rate for the three months ended March 31,
2004 was 36.3 percent compared with 34.4 percent for the same period in 2003.
The Company estimates that its effective tax rate should approximate 36 percent
for 2004. The increase in the tax rate is principally due to a change in the mix
of foreign earnings to countries with higher tax rates and an increase in
domestic earnings (relative to total earnings), which are generally taxed at a
higher rate than earnings from the Company's foreign operations.

                           OTHER FINANCIAL INFORMATION

      The Company's current ratio was 1.8 to 1 at both March 31, 2004 and
December 31, 2003.

      For the three months ended March 31, 2004, cash of $98 million was
provided by operating activities. Cash used for financing activities was $149
million, including $76 million for cash dividends paid and $422 million for the
acquisition and retirement of Company common stock in open-market transactions.
Cash provided by financing activities included primarily $299 million for the
issuance of notes (net of issuance costs) and $55 million from interest rate
swap transactions. Cash used for investing activities was $85 million, including
$55 million for capital expenditures and $47 million for the net purchase of
marketable securities and other investments. Cash held by discontinued
operations was $32 million at March 31, 2004.

      First quarter 2004 cash from operations was affected by an expected and
annually recurring first quarter increase in accounts receivable as compared
with December 31, 2003.

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

      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
of the Condensed Consolidated Financial Statements discusses specific claims
against the Company and its subsidiary, Behr Process Corporation, with respect
to certain exterior wood coating products formerly manufactured by Behr.

      In the first quarter of 2004, the Company issued $300 million of
three-year notes (floating rate based on LIBOR plus .25%); the Company also has
$261 million of debt due in early May 2004.

      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.

                             OUTLOOK FOR THE COMPANY

The Company's favorable sales performance has continued early in the second
quarter with April sales up in the mid-teens. The Company also expects that
certain operating expenses for the year will continue to increase, particularly
for energy and certain material costs. Based on current business trends, the
Company continues to be optimistic and expects to achieve record sales and
earnings for the year 2004.

                           FORWARD-LOOKING STATEMENTS

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

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
            March 31, 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.
