                                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
     September 30, 2002 and the results of operations for the three months and
     nine months ended September 30, 2002 and 2001 and changes in cash flows for
     the nine months ended September 30, 2002 and 2001. The condensed
     consolidated balance sheet at December 31, 2001 was derived from audited
     financial statements.

     Goodwill and Other Intangible Assets

     On January 1, 2002, Statement of Financial Accounting Standards ("SFAS")
     No. 142, "Goodwill and Other Intangible Assets," became effective. In
     accordance with SFAS No. 142, the Company is no longer recording
     amortization expense related to goodwill and other indefinite-lived
     intangible assets. The Company has provided a supplemental disclosure of
     adjusted net income and basic and diluted earnings per common share for the
     three months and nine months ended September 30, 2001 on the condensed
     consolidated statement of operations to exclude goodwill amortization
     expense. The Company will test the impairment of goodwill and other
     indefinite-lived intangible assets on an annual basis utilizing a
     discounted cash flow model in the fourth quarter of each year. Intangible
     assets with finite useful lives will be amortized over their useful lives.
     The Company will evaluate the remaining useful life of amortizable
     intangible assets for each reporting period to determine whether events and
     circumstances warrant a revision to the remaining periods of amortization.

     The Company completed the two-step transitional goodwill impairment testing
     in the second quarter of 2002. The first step of the test was to perform an
     assessment of whether there is an indication that goodwill is impaired. To
     the extent that an indication of impairment existed, the Company performed
     a second test to measure the amount of the impairment. The Company tested
     for impairment of its reporting units by comparing fair value to carrying
     value. Fair value was determined using a discounted cash flow method. This
     evaluation indicated that goodwill recorded for certain of the Company's
     business units, principally in Europe, were impaired. Certain of the
     Company's European businesses have been affected by continued weak market
     and economic conditions. On adoption of SFAS No. 142, a non-cash impairment
     charge of $92.4 million, net of income tax benefit of $24.4 million, was
     recognized as a cumulative effect of change in accounting principle in the
     first half of 2002, effective January 1, 2002. Impairment adjustments, if
     any, recorded in the future, are required to be recorded as operating
     expenses.

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


(A)  Additions to the carrying amount of goodwill include acquisitions and other
     purchase price adjustments. For the nine months ended September 30, 2002,
     additions principally include acquisitions of $890 million, the payment of
     approximately $38 million of additional contingent consideration for prior
     years' acquisitions and other adjustments related to the finalization of
     certain purchase price allocations.

(B)  Other changes to the carrying amount of goodwill principally include
     foreign currency translation adjustments.

     Other indefinite-lived intangible assets include registered trademarks of
     $220 million at September 30, 2002. The carrying value of the Company's
     definite-lived intangible assets is $134.8 million at September 30, 2002
     (net of accumulated amortization of $38.6 million) and principally includes
     customer relationships and non-compete agreements, with a weighted average
     amortization period of 9 years. Amortization expense related to the
     definite-lived intangible assets was approximately $17 million for the nine
     months ended September 30, 2002.

     Recently Issued Accounting Standards

     On January 1, 2002, SFAS No. 144, "Accounting for the Impairment or
     Disposal of Long-Lived Assets" became effective. This statement addresses
     financial accounting and reporting for the impairment or disposal of
     long-lived assets. The adoption of SFAS No. 144 did not have a material
     effect on the Company's consolidated financial statements.

     Emerging Issues Task Force ("EITF") Issue No. 01-9, "Accounting for
     Consideration Given by a Vendor to a Customer," became effective for the
     Company in the first quarter of 2002. EITF No. 01-9 requires that certain
     expenses, including co-operative advertising expenses and other
     customer-related incentives, be recorded as a reduction in sales unless
     certain conditions are met. The adoption of EITF No. 01-9 resulted in the
     reclassification of $20 million and $56 million of co-operative advertising
     expenses from selling expense to a reduction in sales for the three months
     and nine months ended September 30, 2001, respectively. This
     reclassification did not result in a change in net income (loss) or
     earnings (loss) per common share.

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

Note A - concluded:

     In June 2002, the Financial Accounting Standards Board ("FASB") issued SFAS
     No. 146, "Accounting for Costs from Exit or Disposal Activities" which
     requires, among other things, that a liability for costs associated with an
     exit or disposal activity be recognized when the liability is incurred. The
     adoption of SFAS No. 146 is effective for all exit or disposal activities
     subsequent to December 31, 2002. The Company is currently evaluating the
     impact that SFAS No. 146 will have on its consolidated financial
     statements.

     Certain prior-year amounts have been reclassified to conform to the 2002
     presentation in the condensed consolidated financial statements.

B.   Depreciation and amortization expense was $164 million and $204 million for
     the nine months ended September 30, 2002 and 2001, respectively.

C.   The Company has investments principally in U.S. marketable equity
     securities and bond funds (approximately $141 million) at September 30,

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

Note D - concluded:

     In the third quarter of 2002, the Company also acquired Service Partners
     LLC, a distributor and installer of insulation and other building products
     (Installation and Other Services segment). The aggregate net purchase price
     was approximately $735 million, including $411 million of cash, 11.6
     million shares of Company common stock valued at $320 million
     (approximately $27.52 per common share, the guaranteed share price) and
     assumed debt of $4 million. The acquisition of Service Partners allows the
     Company to accelerate its growth in the Installation and Other Services
     segment by adding to the Company's strategy of offering value-added
     services to major customers, particularly homebuilders, and to expand sales
     of certain of the Company's existing products through Service Partners'
     distribution network.

     The results of Service Partners are included in the condensed consolidated
     financial statements from the date of acquisition. Had Service Partners
     been acquired effective January 1, 2001, pro forma unaudited consolidated
     net sales, income (loss) before cumulative effect of accounting change, net
     income and diluted earnings (loss) per common share would have been as

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

Note E - concluded:

     Income (loss) per common share amounts for the first three quarters of 2002
     and 2001 do not total to the per common share amounts for the nine months
     ended September 30, 2002 and 2001 due to the timing of capital stock
     issuances and the effect of contingently issuable shares.

     The outstanding preferred stock, which is convertible into Company common
     stock and carries substantially the same attributes as Company common
     stock, has been treated as if converted in the computation of basic and
     diluted common shares.

     Approximately 24 million common shares for both the three months and nine
     months ended September 30, 2002 and 19.4 million and 6.5 million weighted
     average common shares for the three months and nine months ended September
     30, 2001, respectively, 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, 2002 and 2001, they were not
     convertible according to their terms. Additionally, for the three months
     and nine months ended September 30, 2002, 3.5 million and 3.3 million
     common shares, respectively, and 2.4 million common shares for both the
     three months and nine months ended September 30, 2001 related to stock
     options were excluded from the computation of diluted earnings per common
     share due to their anti-dilutive effect since the exercise price was
     greater than the stock price at September 30.

     For the three months ended September 30, 2001, 20.8 million contingent
     common shares and 2.5 million stock option common shares were not included
     in diluted shares due to their anti-dilutive effect since the Company
     recorded a net (loss) in the third quarter of 2001.

F.   In December 2000, the Company adopted a plan to dispose of several
     businesses that the Company believed were not core to its long-term growth
     strategies. In the first quarter of 2002, the Company sold its subsidiary,
     StarMark Cabinetry, Inc., for approximate book value. StarMark was included
     in the Cabinets and Related Products segment and had annual sales of
     approximately $50 million.

G.   As disclosed in the Company's 2001 Form 10-K, the carrying value of the
     Company's investment in Furnishings International Inc. ("FII") was adjusted
     in 2001 to the estimated fair value of proceeds expected to be received
     from the liquidation of FII in satisfaction of amounts due to the Company
     for its investment in pay-in-kind junior subordinated debt securities of
     FII and certain advances to FII (collectively "FII debt").

     During the second quarter of 2002, FII completed the disposition of its
     operations. The fair value of the remaining net assets of FII represents
     proceeds for the Company's investment in FII debt. The assets and
     liabilities are primarily comprised of notes receivable, 4 million shares
     of Furniture Brands International common stock and pension obligations of
     approximately $75 million. Certain non-Masco shareholders of FII have
     contributed their FII shares back to FII resulting in Masco becoming the
     majority shareholder. Accordingly, the assets and liabilities of FII have
     been recorded in the Company's condensed consolidated financial statements.

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

H.   In the third quarter of 2001, the Company recorded an aggregate $530
     million pre-tax, non-cash charge for the write-down of certain investments,
     including the Company's investments in FII and other non-operating assets.
     The furniture industry in general and FII in particular had been adversely
     affected by the ongoing economic weakness in its markets, the bankruptcies
     of a number of major retailers and import competition. In light of these
     factors, the Company reevaluated the carrying value of its investment in
     FII and recorded a $460 million pre-tax, non-cash charge to write down this
     investment to its estimated current fair value. The Company also recorded a
     $70 million pre-tax, non-cash charge for an other-than-temporary decline in
     the fair value of certain of the Company's, principally technology-related,
     investments.

     Other interest income for the nine months ended September 30, 2001 included
     $30.3 million of interest income from indebtedness of Furnishings
     International Inc. ("FII"). No such interest income was recorded for the
     three months ended September 30, 2001. The recording of such interest
     income was discontinued effective July 1, 2001 due to the impairment of the
     Company's investment in FII.

     In the third quarter of 2002, the Company incurred $13.8 million of losses
     related to interest ratelock transactions entered into in anticipation of
     the Company issuing fixed rate debt in the third quarter of 2002. There
     were no interest ratelock agreements outstanding at September 30, 2002.

I.   In May 2002, the Company sold 22 million shares of Company common stock in
     a public offering, resulting in net proceeds to the Company of $598.3
     million (net of issuance costs of $14.4 million). On June 24, 2002, the
     Company issued $500 million of 5-7/8% notes due 2012, resulting in net
     proceeds of $490.8 million. On August 20, 2002, the Company issued $300
     million of 4-5/8% notes due 2007, resulting in net proceeds of $296.7
     million. On August 20, 2002, the Company also issued $300 million of 6-1/2%
     notes due 2032, resulting in net proceeds of $294.6 million. These proceeds
     are net of aggregate debt issuance costs of $17.9 million, which are being
     amortized over the issue lives of the related notes. The Company used the
     proceeds from the equity and debt issuances to reduce bank indebtedness
     and for other general corporate purposes, including investments in
     marketable securities and other investments.

     At September 30, 2002, the maturities of short-term and long-term debt
     during each of the next five years were approximately as follows: 2003 -
     $312 million; 2004 - $525 million; 2005 - $10 million; 2006 - $808 million;
     and 2007 - $303 million.

     On July 19, 2002, the Company announced that it amended the terms of its
     Zero Coupon Convertible Senior Notes ("Notes") due July 20, 2031 to permit
     an additional date, April 20, 2004, on which holders, at their option, can
     cause the Company to repurchase the Notes, at the then accreted value of
     $429.57 per Note, payable by the Company in cash on April 26, 2004. Under
     the original terms of the Notes, holders of $26.4 million of Notes required
     the Company to repurchase, for $10.7 million cash, the accreted value of
     such Notes on July 23, 2002.

     Subsequent Event: On October 16, 2002, the Company issued $350 million of
     5-7/8% notes due 2012, resulting in net proceeds of $356 million, including
     a premium of $8.3 million and debt issuance costs of $2.3 million, which
     are being amortized through 2012. The Company subsequently filed
     Registration Statements with the Securities and Exchange Commission,
     pending effectiveness, to increase the unallocated shelf registration
     pursuant to which the Company is able to issue up to a combined $2 billion
     of debt and equity securities and 50 million shares of Company common
     stock.

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

     In May 1998, a civil suit was filed in the Grays Harbor County, Washington
     Superior Court against Behr Process Corporation, a subsidiary of the
     Company. The case involves four exterior wood coating products, which
     represent a relatively small part of Behr's total sales. The plaintiffs
     allege, among other things, that after applying these products, the wood
     surfaces suffered excessive mildewing in the very humid climate of western
     Washington. The trial court certified the case as a class action, including
     all purchasers of the products who reside in nineteen counties in western
     Washington. Behr denies the allegations. In May 2000, the court entered a
     default against Behr as a discovery sanction. Thereafter, the jury returned
     a verdict awarding damages to the named plaintiffs. The damages awarded for
     the eight homeowner claims (excluding one award to the owners of a vacation
     resort) ranged individually from $14,500 to $38,000. The awards were
     calculated using a formula based on the product used, the nature and square
     footage of wood surface and certain other allowances. Under the verdict,
     the same formula will be used for calculating awards on claims that may be
     submitted by the subject purchasers of these products. In addition, the
     court granted the plaintiffs' motion for attorneys' fees. Behr appealed the
     trial court judgment to the Court of Appeals of Washington. On September
     13, 2002, the Court of Appeals issued its opinion, ruling in favor of the
     plaintiffs on substantially all issues. The opinion was unexpected in light
     of the unprecedented and disproportionate extent of the default sanction
     ordered by the trial court and the belief by the Company and its outside
     legal counsel that the rulings by the trial court had errors that would be
     reversed by the appellate review. Following the trial court judgment in the
     Washington case, Behr and the Company were served with 21 complaints filed
     by consumers in state courts in Alabama, Alaska, California, Illinois, New
     Jersey, New York, Oregon, and Washington, and in British Columbia, Canada
     and Ontario, Canada. The complaints allege that certain of Behr's exterior
     wood coating products fail to perform as warranted, resulting in damage to
     the plaintiffs' wood surfaces. Trial courts in Washington and Illinois
     have certified their cases as national class actions. In addition, the
     Company has recently been advised that one state is conducting an
     investigation into the effectiveness of certain of these products.

Note M - continued:

     On October 29, 2002, the Company announced settlements to resolve all of
     the class actions in the United States. The Company and attorneys
     representing class members have reached an agreement in principle to settle
     the 19-county Washington lawsuit. The parties are negotiating a definitive
     settlement agreement that the Company expects to submit within 30 days for
     preliminary approval by the trial court. At that time a fairness hearing
     will be scheduled following which the parties will request that the court
     grant final approval of the settlement. Under the terms of the settlement,
     eligible class members who successfully complete the claims process will
     receive a cash award based on the product used, the type and square footage
     of wood surface and certain other allowances. The awards will be calculated
     using the damage formulas in the judgment entered by the trial court. The
     Company will pay cash awards to class members, the costs of notice to the
     class, the costs to administer the claims process and certain other
     expenses, up to an aggregate maximum of $55 million. In addition, the
     Company will pay class counsel fees awarded by the trial court up to a
     maximum of $12.5 million. Based upon the sales volume of the related
     products during the class period, the damage formulas ordered by trial
     court, the expected class size, the estimated number of claims that would
     be filed on a timely basis, the estimated average cost per claim, and the
     experience of the Company's legal counsel with class action settlements,
     the Company estimates that the total cost of the Washington settlement will
     approximate the maximum, $67.5 million, excluding amounts that the Company
     expects to recover from liability insurers and other third parties.

     The Company has also reached a settlement that management expects will
     resolve all other class actions pending in the U.S. The settlement has
     received preliminary court approval. A fairness hearing has been scheduled
     for March 6, 2003, at which time the court will be requested to enter an
     order of final approval and judgment. The settlement requires the dismissal
     of all other related litigation pending in the United States. Counsel for
     plaintiffs in the Illinois case have taken action in the Illinois court to
     prevent the Company from proceeding with the settlement. The Company
     intends to oppose this effort and any change in the existing terms of the
     settlement. The settlement provides that eligible class members who
     successfully complete the claims process can elect to receive either a
     merchandise certificate for a discount on the purchase of Behr products, or
     a cash award based on the product used, the square footage of wood surface,
     proof of purchase, the interval of time between product application and the
     appearance of mildew, and the extent of mildew damage. The Company will pay
     a settlement amount of up to $107.5 million, which will include total cash
     payments to eligible class members, the cost of notice to the class, the
     cost to administer the claims process, and the face value of merchandise
     certificates issued to eligible claimants up to $7.5 million. If the
     aggregate face value of merchandise certificates issued exceeds $7.5
     million, the excess will not be credited against the $107.5 million
     settlement amount but will be settled by issuance of additional merchandise
     certificates. The settlement also provides that the Company will pay class
     counsel fees awarded by the trial court, up to a maximum of $25 million.
     Based upon the sales volume of the related products during the class
     period, the expected class size, the estimated number of claims that would
     be filed on a timely basis, the estimated size and mix of claims (coupon
     versus cash), the estimated average cost per claim and the experience of
     the Company's legal counsel with class action settlements, the Company
     estimates that the cost of the settlement will range from $96 million to
     $136 million (including adjustments due to the $107.5 million limit),
     excluding amounts that the Company expects to recover from liability
     insurers. This estimate includes costs (for notice and claims
     administration) of $5 to $6 million, attorney fees of $25 million,
     merchandise certificate costs ranging from $5 to $11 million, and cash
     awards ranging from $61 to $102 million.

Note M - concluded:

     Management believes, based on the advice of outside counsel, that these
     settlements described above will receive final approval without substantial
     changes, although there can be no assurance in that regard. The Company
     estimates that the combined cost of both settlements and the Company's
     additional legal costs (estimated at $2 million) will range from $166
     million to $206 million. The Company has concluded that no amount within
     that range is more likely than any other, and therefore has reflected $166
     million as a liability in the third quarter 2002 consolidated financial
     statements in accordance with generally accepted accounting principles. The
     Company is currently negotiating its liability insurers' contribution to
     the cost of the settlements. However, no insurance amounts have been
     recorded as of September 30, 2002. Recoveries from liability insurers or
     other third parties will be recorded at such time as they are agreed to,
     or otherwise received. After receiving final court approval, the Company
     expects that payment of the settlements will commence in the second
     quarter of 2003 and will be completed by the first quarter of 2004.

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

                                    NET SALES

     Net sales for the three-month and nine-month periods ended September 30,
2002 increased 13 percent and 12 percent, respectively, from the comparable
periods in 2001. Excluding acquisitions and divestitures, net sales increased 10
percent and 9 percent for the three-month and nine-month periods ended September
30, 2002, respectively, over the comparable periods of the prior year. The
increase in net sales in 2002 is principally due to improved economic and
business conditions in certain of the Company's markets, which contributed to
higher unit sales volume of certain products, particularly cabinets,
architectural coatings, decorative hardware, vinyl windows and faucets.

                                OPERATING MARGINS

     The Company's gross profit margins increased to 31.8 percent and 31.9
percent for the three-month and nine-month periods ended September 30, 2002,
respectively, from 30.5 percent and 30.1 percent for the comparable periods in
2001, respectively. The increase in gross profit margin reflects sales volume
increases in all of the Company's business segments as well as the favorable
influence of the Company's profit improvement initiatives. Selling, general and
administrative expenses, including general corporate expense but excluding the
litigation settlement charge, as a percentage of sales decreased to 15.1 percent
and 15.9 percent for the three-month and nine-month periods ended September 30,
2002, respectively, as compared with 15.4 percent and 16.1 percent for the
comparable periods of the prior year, respectively.

     The Company's operating profit margins, before the charge for litigation
settlement in 2002, and after general corporate expense and excluding goodwill
amortization expense in 2001, was 16.7 percent and 16.0 percent for the
three-month and nine-month periods ended September 30, 2002, respectively, as
compared with 15.1 percent and 14.0 percent for the comparable periods in 2001,
respectively. Operating profit margins, before both general corporate expense
and the litigation settlement charge and excluding goodwill amortization expense
in 2001, were 17.7 percent and 17.0 percent for the three-month and nine-month
periods ended September 30, 2002, respectively, as compared with 16.2 percent
and 15.2 percent for the comparable periods in 2001, respectively. The Company's
operating profit margin increased in the third quarter and the nine months ended
September 30, 2002, as compared with the comparable periods in 2001, principally
as a result of fixed costs being spread over a higher sales level as well as
the favorable influence of the Company's profit improvement initiatives.

                       SEGMENT AND GEOGRAPHIC AREA RESULTS

     Changes in net sales in the following discussion exclude the impact of
acquisitions and divestitures. Changes in operating profit margin in the
following discussion exclude goodwill amortization expense and the charge for
litigation settlement.

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

     Net sales of Cabinets and Related Products increased 13 percent and 10
percent for the three-month and nine-month periods ended September 30, 2002,
respectively, from the comparable periods of the prior year due to increased
sales volume of cabinets largely through expansion of North American retail
distribution channels as well as new product introductions. Operating profit
margins for the Cabinets and Related Products segment were 15.4 percent and 13.5
percent for the three-month and nine-month periods ended September 30, 2002,
respectively, compared with 9.4 percent and 11.1 percent for the comparable
periods of the prior year, respectively. The increase in operating profit
margins is primarily due to increased unit sales volume, profit improvement
initiatives and the reduction of plant shutdown costs and other asset
write-downs, offset in part by costs related to a discontinued product line.

     Net sales of Plumbing Products increased 9 percent and 11 percent for the
three-month and nine-month periods ended September 30, 2002, respectively, from
the comparable periods of the prior year. These increases represent the
favorable influence of new product introductions which contributed to higher
unit sales volume of faucets to retailers in 2002 as well as increased growth in
the wholesale distribution channels. The increase in sales of Plumbing Products
in 2002 also includes the influence of inventory reduction programs of certain
key customers in the first six months of 2001, which reduced sales for 2001 and
favorably influenced the first nine months of 2002 versus 2001 comparisons.
Operating profit margins for the Plumbing Products segment were 15.5 percent and
16.0 percent for the three-month and nine-month periods ended September 30,
2002, respectively, compared with 16.0 percent and 14.0 percent for the
comparable periods of the prior year. Operating profit margins in the first nine
months of 2002 were primarily favorably affected by the leveraging of fixed
costs over increased unit sales volume as well as the Company's profit
improvement initiatives. Operating profit margins in the third quarter of 2002
were adversely affected by product mix and higher insurance costs compared with
the third quarter of 2001.

     Net sales of Installation and Other Services increased 3 percent for both
the three-month and nine-month periods ended September 30, 2002, from the
comparable periods of the prior year. The increase in net sales attributable to
this segment in 2002 occurred despite lower insulation material purchase costs
and related lower market pricing, which partially offset increases of
non-insulation installed products. Operating profit margins for the Installation
and Other Services segment were 16.8 percent and 17.0 percent for the
three-month and nine-month periods ended September 30, 2002, respectively,
compared with 18.5 percent and 16.6 percent for the comparable periods of the
prior year. Operating profit margins in this segment were affected by lower
margins of acquired companies for the three months ended September 30, 2002 and
product mix for the nine months ended September 30, 2002.

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

     Net sales of Decorative Architectural Products increased 13 percent and 10
percent for the three-month and nine-month periods ended September 30, 2002,
respectively, from the comparable periods of the prior year, due largely to
higher unit sales volume of paints, stains and decorative hardware through North
American retail distribution channels. Operating profit margins for the
Decorative Architectural Products segment were 22.1 percent and 22.2 percent for
the three-month and nine-month periods ended September 30, 2002, respectively,
compared with 21.6 percent and 20.6 percent for the comparable periods of the
prior year. The improvement in operating profit margins for this segment reflect
the leveraging of fixed costs over higher unit sales volume, the absence of
plant start-up and relocation costs that contributed to lower operating margins
in 2001 and lower levels of bad debt expense and certain asset write-downs in
2002 compared with 2001.

     Net sales of Other Specialty Products increased 13 percent and 1 percent
for the three-month and nine-month periods ended September 30, 2002,
respectively, from the comparable periods of the prior year. The increase in net
sales in the third quarter 2002 is primarily due to increased sales of vinyl
windows. A weaker U.S. dollar also had a favorable effect on the translation of
local currencies of European operations included in this segment. Operating
profit margins were 22.1 percent and 19.8 percent for the three-month and nine-
month periods ended September 30, 2002, respectively, compared with 22.3
percent and 17.8 percent for the comparable periods of the prior year. The
improvement in operating profit margins in the nine months ended September 30,
2002 reflects the positive influence of recent acquisitions, which in aggregate
have higher operating profit margins than the segment average.

     Net sales from North American operations increased 10 percent for both the
three-month and nine-month periods ended September 30, 2002 from the comparable
periods of 2001. Operating profit margins for North American operations were
18.4 percent and 17.7 percent for the three-month and nine-month periods ended
September 30, 2002, respectively, compared with 16.9 percent and 15.7 percent
for the comparable periods of the prior year. The increase in operating profit
margins principally reflects the leveraging of fixed costs over increased sales
volume, product mix and the influence of the Company's profit improvement
initiatives. Additionally, in 2001, North American operations were negatively
affected by plant shutdown charges and asset write-downs that favorably
influenced the 2002 versus 2001 comparisons.

     Net sales from International operations increased 11 percent and 3 percent
for the three-month and nine-month periods ended September 30, 2002,
respectively, from the comparable periods of 2001. A weaker U.S. dollar had a
favorable influence on the translation of International sales in the third
quarter of 2002. International sales in local currencies increased 2 percent for
the third quarter 2002 and were flat for the nine-month period ended September
30, 2002. Operating profit margins for International operations were 13.9
percent and 13.3 percent for the three-month and nine-month periods ended
September 30, 2002, respectively, compared with 12.5 percent and 12.3 percent
for the comparable periods of the prior year. Operating profit margins for
International operations benefited from profit improvement initiatives as well
as the positive influence of recent acquisitions which in aggregate have higher
operating profit margins than the International operations' average.

ITEM 2.              MANAGEMENT'S DISCUSSION AND ANALYSIS OF

                           OTHER INCOME (EXPENSE), NET

     Included in other interest income for the nine months ended September 30,
2001 is $30.3 million of interest income from indebtedness of Furnishings
International Inc. ("FII"). No such interest income was recorded for the three
months ended September 30, 2001. The recording of such interest income was
discontinued effective July 1, 2001 due to the impairment of the Company's
investment in FII.

     In the third quarter of 2001, the Company recorded an aggregate $530
million pre-tax, non-cash charge for the write-down of certain investments,
including the Company's investments in FII and other non-operating assets.
The furniture industry in general and FII in particular had been adversely
affected by the ongoing economic weakness in its markets, the bankruptcies of
a number of major retailers and import competition. In light of these factors,
the Company reevaluated the carrying value of its investment in FII and
recorded a $460 million pre-tax, non-cash charge to write down this investment
to its estimated current fair value. The Company also recorded a $70 million
pre-tax, non-cash charge for an other-than-temporary decline in the fair value
of certain of the Company's, principally technology-related, investments.

     Other, net for the three-month and nine-month periods ended September 30,
2002 includes $1.6 million and $(27.2) million, respectively, of realized gains
(losses), net from the sale of marketable securities, dividend income from
marketable securities of $1.5 million and $2.8 million, respectively, and $2.3
million and $6.7 million of income and gains (losses), net regarding other
investments, respectively. In addition, in the third quarter of 2002, the
Company incurred $13.8 million of losses related to interest ratelock
transactions entered into in anticipation of the Company issuing fixed rate debt
in the third quarter of 2002. There were no interest ratelock agreements
outstanding at September 30, 2002. Other, net for the three-month and nine-
month periods ended September 30, 2001 included $(3.2) million and $(.2)
million, respectively, of realized gains (losses), net from the sale of
marketable securities, dividend income from marketable securities of $.7 million
and $1.9 million, respectively, and $5.0 million and $9.7 million, respectively,
of income and gains (losses), net regarding other investments.

     Interest expense for the three-month and nine-month periods ended September
30, 2002 was $61.0 million and $170.3 million, respectively, compared with $61.6
million and $179.3 million for the comparable periods of the prior year.

                 INCOME AND EARNINGS PER COMMON SHARE BEFORE THE
                     CUMULATIVE EFFECT OF ACCOUNTING CHANGE

     Net income (loss) for the third quarter of 2002 increased to $122.8 million
and diluted earnings (loss) per common share increased to $.24 compared with
$(.39) per common share ($(.35) excluding goodwill amortization expense) for the
comparable period of 2001. Income before the cumulative effect of accounting
change for the nine-month period ended September 30, 2002 was $487.3 million and
related diluted earnings per common share was $.96 compared with $.15 per common
share ($.27 excluding goodwill amortization expense) for the comparable period
of the prior year.

                                MASCO CORPORATION

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

     The three-month and nine-month periods ended September 30, 2002 were
impacted by the charge for the litigation settlement of $166 million. The
three-month and nine-month periods ended September 30, 2001 were impacted by a
$530 million non-cash, pre-tax charge for the write-down of certain investments,
including the Company's investment in Furnishings International Inc. and other
non-operating assets.

     The Company's effective tax rate, excluding the charge for litigation
settlement, was 34.2 percent and 34.1 percent for the third quarter and nine
months ended September 30, 2002, respectively, prior to the accounting change
effect, as compared with 35.0 percent (36.8 percent and 27.6 percent for the
three months and nine months ended September 30, 2001, respectively, excluding
goodwill amortization expense) for both of the comparable periods of the prior
year. The Company estimates that its effective tax rate should approximate 34.5
percent for the full year 2002, excluding the litigation settlement charge and
the accounting change effect.

                     CUMULATIVE EFFECT OF ACCOUNTING CHANGE

     On January 1, 2002, Statement of Financial Accounting Standards ("SFAS")
No. 142, "Goodwill and Other Intangible Assets," became effective. In accordance
with SFAS No. 142, the Company is no longer recording amortization expense
related to goodwill and other indefinite-lived intangible assets. The Company
adopted a new critical accounting policy regarding goodwill and other
indefinite-lived intangible assets. See Note A of the Condensed Consolidated
Financial Statements.

     The Company completed the two-step transitional goodwill impairment testing
in the second quarter of 2002. The first step of the test was to perform an
assessment of whether there is an indication that goodwill is impaired. To the
extent that an indication of impairment existed, the Company performed a second
test to measure the amount of the impairment. The Company tested for impairment
of its reporting units by comparing fair value to carrying value. Fair value was
determined using a discounted cash flow method. This evaluation indicated that
goodwill recorded for certain of the Company's business units, principally in
Europe, were impaired. Certain of the Company's European businesses have been
affected by continued weak market and economic conditions. On adoption of SFAS
No. 142, a non-cash impairment charge of $92.4 million, net of income tax
benefit of $24.4 million, was recognized as a cumulative effect of change in
accounting principle in the first half of 2002, effective January 1, 2002.

     Determining market values using the discounted cash flow method requires
the Company to make significant estimates and assumptions including long-term
projections of cash flows, market conditions and appropriate discount rates. The
Company's judgments are based on historical experience, current market trends
and other information. While the Company believes that the estimates and
assumptions underlying the valuation model are reasonable, different assumptions
could result in a different outcome.

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

                           OTHER FINANCIAL INFORMATION

     The Company's current ratio was 1.9 to 1 at September 30, 2002, as compared
with 2.1 to 1 at December 31, 2001; this decrease was due principally to the
reclassification from long-term debt to short-term debt of $200 million of
6-1/8% notes due September 2003.

     For the nine months ended September 30, 2002, cash of $690.8 million was
provided by operating activities. Cash provided by financing activities was
$675.0 million, including $1,082.1 million from the issuance of fixed rate notes
in 2002, and $598.3 million from the issuance of Company common stock. Cash used
for financing activities included a $717.2 million net decrease in long-term
debt, primarily related to payments of bank debt, $60.5 million for the
acquisition of Company common stock in open-market transactions, $31.3 million
for the acquisition of Company common stock for the Company's long-term stock
incentive award plan, and $196.5 million for cash dividends paid. Cash used for
investing activities was $1,077.7 million, including $660.8 million for
acquisitions, $175.5 million for capital expenditures, and $304.3 million for
the net purchases of marketable securities and other investments. Cash provided
by investing activities included $15.4 million from the disposition of a
business and $47.4 million from other items. The aggregate of the preceding
items represents a net cash inflow of $288.1 million.

     Days sales in accounts receivable increased to 57 days from 52 days at
September 30, 2001, primarily due to an extension of payment terms with a major
customer.

     In September 2002, the Company increased its quarterly cash dividend to
$.14 from $.135 per common share. This marks the 44th consecutive year in which
dividends have been increased.

     In May 2002, the Company sold 22 million shares of Company common stock in
a public offering, resulting in net proceeds to the Company of $598.3 million
(net of issuance costs of $14.4 million). On June 24, 2002, the Company issued
$500 million of 5-7/8% notes due 2012, resulting in net proceeds of $490.8
million. On August 20, 2002, the Company issued $300 million of 4-5/8% notes due
2007, resulting in net proceeds of $296.7 million. On August 20, 2002, the
Company also issued $300 million of 6-1/2% notes due 2032, resulting in net
proceeds of $294.6 million. These proceeds are net of aggregate debt issuance
costs of $17.9 million which are being amortized over the issue lives of the
related notes. The Company used the proceeds from the equity and debt issuances
to reduce bank indebtedness and for other general corporate purposes, including
investments in marketable securities and other investments.

     On July 19, 2002, the Company announced that it amended the terms of its
Zero Coupon Convertible Senior Notes ("Notes") due July 20, 2031 to permit an
additional date, April 20, 2004, on which holders, at their option, can cause
the Company to repurchase the Notes, at the then accreted value of $429.57 per
Note, payable by the Company in cash on April 26, 2004. Under the original terms
of the Notes, holders of $26.4 million of Notes required the Company to
repurchase, for $10.7 million cash, the accreted value of such Notes on July 23,
2002.

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

     Subsequent Event: On October 16, 2002, the Company issued $350 million of
5-7/8% notes due 2012, resulting in net proceeds of $356 million, including a
premium of $8.3 million and debt issuance costs of $2.3 million, which are being
amortized through 2012. The Company subsequently filed Registration Statements
with the Securities and Exchange Commission, pending effectiveness, to increase
the unallocated shelf registration pursuant to which the Company is able to
issue up to a combined $2 billion of debt and equity securities and 50 million
shares of Company common stock.

     As disclosed in the Company's 2001 Form 10-K, the carrying value of the
Company's investment in Furnishings International Inc. ("FII") was adjusted in
2001 to the estimated fair value of proceeds expected to be received from the
liquidation of FII in satisfaction of amounts due to the Company for its
investment in pay-in-kind junior subordinated debt securities of FII and certain
advances to FII (collectively "FII debt").

     During the second quarter of 2002, FII completed the disposition of its
operations. The fair value of the remaining net assets of FII represents
proceeds for the Company's investment in FII debt. The assets and liabilities
are primarily comprised of notes receivable, 4 million shares of Furniture
Brands International common stock and pension obligations of approximately $75
million. Certain non-Masco shareholders of FII have contributed their FII shares
back to FII resulting in Masco becoming the majority shareholder. Accordingly,
the assets and liabilities of FII have been recorded in the Company's condensed
consolidated financial statements.


     The Company is subject to lawsuits and claims pending or asserted with
respect to matters generally arising in the ordinary course of business. Note M
of the Condensed Consolidated Financial Statements discusses specific claims
against the Company and its subsidiary, Behr Process Corporation, with respect
to several of Behr's exterior wood coating products.

     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.

                      RECENTLY ISSUED ACCOUNTING STANDARDS

     On January 1, 2002, Statement of Financial Accounting Standards ("SFAS")
No. 142, "Goodwill and Other Intangible Assets," became effective. In accordance
with SFAS No. 142, the Company is no longer recording amortization expense
related to goodwill and other indefinite-lived intangible assets. See
"Cumulative Effect of Accounting Change" for additional discussion regarding the
adoption of this standard.

     On January 1, 2002, SFAS No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets" became effective. This statement addresses
financial accounting and reporting for the impairment or disposal of long-lived
assets. The adoption of SFAS No. 144 did not have a material effect on the
Company's consolidated financial statements.

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

     Emerging Issues Task Force ("EITF") Issue No. 01-9, "Accounting for
Consideration Given by a Vendor to a Customer," became effective for the Company
in the first quarter of 2002. EITF No. 01-9 requires that certain expenses,
including co-operative advertising expenses and other customer-related
incentives, be recorded as a reduction in sales unless certain conditions are
met. The adoption of EITF No. 01-9 resulted in the reclassification of $20
million and $56 million of co-operative advertising expenses from selling
expense to a reduction in sales for the three months and nine months ended
September 30, 2001, respectively. This reclassification did not result in a
change in net income (loss) or earnings (loss) per common share.

     In June 2002, the FASB issued SFAS No. 146, "Accounting for Costs from Exit
or Disposal Activities" which requires, among other things, that a liability for
costs associated with an exit or disposal activity be recognized when the
liability is incurred. The adoption of SFAS No. 146 is effective for all exit or
disposal activities subsequent to December 31, 2002. The Company is currently
evaluating the impact that SFAS No. 146 will have on its consolidated financial
statements.

                             OUTLOOK FOR THE COMPANY

     The Company's internal sales growth has continued to trend upward. The
upward trend in sales includes increased sales to retailers with above-average
increases in sales of cabinets, architectural coatings, decorative hardware and
faucets. The Company has also recently implemented several programs aimed at
improving return on assets and cash flow; the Company anticipates significant
future improvement in both of these areas which should contribute to future
margin improvement. Due to seasonal factors, the Company expects margins in the
fourth quarter to be modestly lower than margins achieved in the second and
third quarters.

                           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.
