                                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, 2006 and the results of operations and changes in cash flows for
     the three months ended March 31, 2006 and 2005. The condensed consolidated
     balance sheet at December 31, 2005 was derived from audited financial
     statements.

     Certain prior-year amounts have been reclassified to conform to the 2006
     presentation in the condensed consolidated financial statements. The
     results of operations related to 2005 discontinued operations have been
     separately stated in the accompanying condensed consolidated statements of
     income for the three months ended March 31, 2005. In the Company's
     condensed consolidated statements of cash flows for the three months ended
     March 31, 2005, the 2005 cash flows of discontinued operations are not
     separately classified.

     STOCK OPTIONS AND AWARDS. On January 1, 2003, the Company elected to
     prospectively change its method of accounting for stock-based compensation
     using the transition method defined by Statement of Financial Accounting
     Standards ("SFAS") No. 148, "Accounting for Stock-Based Compensation -
     Transition Disclosure - an Amendment of SFAS No. 123," and implemented the
     fair value method for determining stock-based compensation expense.
     Accordingly, options granted, modified or settled subsequent to January 1,
     2003 were accounted for using the fair value method, and options granted
     prior to January 1, 2003 were accounted for using the intrinsic value
     method. The following table illustrates the pro forma effect on net income
     and earnings per common share for the three months ended March 31, 2005, as
     if the fair value method were applied to all previously issued, outstanding
     and unvested stock options, in millions except per common share data:

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

B.   Effective January 1, 2006, the Company adopted SFAS No. 123R, "Share-Based
     Payment," using the Modified Prospective Application ("MPA") method. The
     MPA method requires the Company to record expense for unvested stock
     options that were awarded prior to January 1, 2003 through the remaining
     vesting periods. The MPA method does not require the restatement of
     prior-year information. The Company is currently evaluating which tax
     election method it will use to determine the tax windfall or shortfall
     associated with stock options; such evaluation will be completed by the
     fourth quarter of 2006.

     The Company's 2005 Long Term Stock Incentive Plan (the "2005 Plan")
     replaced the 1991 Long Term Stock Incentive Plan (the "1991 Plan") in May
     2005 and provides for the issuance of stock-based incentives in various
     forms. At March 31, 2006, outstanding stock-based incentives were in the
     form of restricted long-term stock awards, stock options, phantom stock
     awards and stock appreciation rights. Additionally, the Company's 1997
     Non-Employee Directors Stock Plan (the "1997 Plan") provides for the
     payment of part of the compensation to non-employee Directors in Company
     common stock. Pre-tax compensation expense related to stock-based
     incentives was as follows for the three months ended March 31, 2006 and
     2005, in millions:

                                         ===    ===


     The income tax benefit related to stock-based compensation expense
     recognized for the three months ended March 31, 2006 was $11 million.

     In the first quarter of 2006, the Company recognized additional pre-tax
     expense of $7 million ($4 million after tax, or $.01 per common share)
     related to the adoption of SFAS No. 123R. In addition, in the first quarter
     of 2006, the Company recorded expense of $3 million (net of income tax
     benefit of $2 million) as a cumulative effect of accounting change, net.

     At March 31, 2006, a total of 23,978,900 shares and 382,300 shares of
     Company common stock were available under the 2005 Plan and the 1997 Plan,
     respectively, for the granting of stock options and other restricted
     long-term stock incentive awards.

     RESTRICTED LONG-TERM STOCK AWARDS

     Long-term stock awards are granted to key employees and non-employee
     Directors of the Company and do not cause net share dilution inasmuch as
     the Company continues the practice of repurchasing and retiring an equal
     number of shares on the open market.

Weighted average grant date fair value (per share)    $30


     The Company continues to measure compensation cost for stock awards at the
     market price of the Company's common stock at the grant date. Effective
     January 1, 2006, such cost is being expensed ratably over the shorter of
     the vesting period of the stock awards, typically 10 years, or the length
     of time until the grantee becomes retirement-eligible at age 65. For stock
     awards granted prior to January 1, 2006, such cost is being expensed over
     the vesting period of the stock awards, typically 10 years, or for
     executive grantees that are, or will become, retirement-eligible, the
     expense is being recognized over five years.

     There was $219 million of total unrecognized compensation expense related
     to unvested stock awards; such awards had a weighted average remaining
     vesting period of seven years. There was $185 million of unrecognized
     compensation cost which was included as a reduction of shareholders' equity
     at December 31, 2005; such cost was reclassified on January 1, 2006 in
     accordance with SFAS No. 123R. As of January 1, 2006, the Company estimated
     a forfeiture rate for long-term stock awards and applied that rate to all
     previously expensed stock awards; such application did not result in a
     change in expense to be recorded as a cumulative effect of accounting
     change.

     The total market value (at the vesting date) of stock award shares which
     vested during the three months ended March 31, 2006 was $34 million.

     STOCK OPTIONS

     Stock options are granted to key employees and non-employee Directors of
     the Company. The exercise price equals the market price of Company common
     stock at the grant date. These options generally become exercisable (vest
     ratably) over five years beginning on the first anniversary from the date
     of grant and expire no later than 10 years after the grant date.
     Restoration stock options under the 1991 Plan become exercisable six months
     from the date of grant. The 2005 Plan does not permit the granting of
     restoration stock options, except for restoration options resulting from
     options previously granted under the 1991 Plan.

     The Company granted 136,000 of primarily restoration stock option shares in
     the first quarter of 2006 with a grant date exercise price range of $29-$33
     per share. In the first quarter of 2006, 250,000 stock option shares were
     forfeited.

     A summary of the status of the Company's stock options for the three months

   Aggregate intrinsic value (A)                       $118 million
   Weighted average remaining option term (in years)      4


(A)  Aggregate intrinsic value is computed using the Company's stock price at
     March 31, 2006 less the exercise price (grant date price) multiplied by the
     number of shares.

     The Company measures compensation cost for stock options using a
     Black-Scholes option pricing model. The expense for unvested stock options
     at January 1, 2006 is based on grant-date fair value of those awards as
     calculated for pro forma disclosures under SFAS No. 123. Effective January
     1, 2006, such cost is being expensed ratably over the shorter of the
     vesting period of the stock options, typically five years, or the length of
     time until the grantee becomes retirement-eligible at age 65. For stock
     options granted prior to January 1, 2006, such cost is being expensed
     ratably over the vesting period of the stock options, typically five years.

     As of March 31, 2006, there was $95 million of aggregate unrecognized
     compensation expense (using the Black-Scholes option pricing model) related
     to unvested stock options; such options had a weighted average vesting
     period of over three years. As of January 1, 2006, the Company estimated a
     forfeiture rate for stock options and applied that rate to all previously
     expensed stock options; such application did not result in a change in
     expense to be recorded as a cumulative effect of accounting change.

     PHANTOM STOCK AWARDS AND STOCK APPRECIATION RIGHTS

     The Company issues phantom stock awards and stock appreciation rights
     ("SARs") to certain non-U.S. employees.

     Phantom stock awards are linked to the value of the Company's common stock
     on the date of grant and are settled in cash upon vesting, typically over
     10 years. The Company continues to account for phantom stock awards as
     liability awards; the compensation cost is initially measured as the market
     price of the Company's common stock at the grant date and is expensed
     ratably over the vesting period. The liability is remeasured and adjusted
     at the end of each reporting period until the award is fully-vested and
     paid to the employees. For the three months ended March 31, 2006, the
     Company granted 91,000 shares of phantom stock awards with an aggregate
     fair value of $3 million and paid $2 million in cash to settle phantom
     stock awards.

     SARs are linked to the value of the Company's common stock and are settled
     in cash upon exercise. On January 1, 2006, the Company changed its method
     of accounting for SARs, in accordance with the provisions of SFAS No. 123R,
     from the intrinsic value method to the fair value method. The fair value
     method requires outstanding SARs to be classified as liability awards and
     valued using a Black-Scholes model at the grant date; such fair value is
     expensed ratably over the vesting period, typically five years. The
     liability is remeasured and adjusted at the end of each reporting period
     until the SARs are exercised and payment is made to the employees or the
     SARs expire. As a result of implementing this change, the Company recorded
     expense of $3 million (net of income tax benefit of $2 million) as a
     cumulative effect of accounting change, net; the Company also recorded
     expense of $2 million related to the valuation of SARs at March 31, 2006.
     The Company did not grant any SARs in the first three months of 2006.

     At March 31, 2006, the Company did not include any common shares related to
     the Zero Coupon Convertible Senior Notes ("Notes") in the calculation of
     diluted earnings per common share, as the price of the Company's common
     stock at March 31, 2006 did not exceed the equivalent accreted value of the
     Notes.

     Additionally, 12.9 million common shares and 0.4 million common shares for
     the three months ended March 31, 2006 and 2005, respectively, related to
     stock options were excluded from the computation of diluted earnings per
     common share due to their antidilutive effect. Effective January 1, 2006,
     the Company changed its method of calculating the dilutive effect of stock
     options in accordance with the provisions of SFAS No. 123R. Such
     calculation now includes the unrecognized compensation expense associated
     with unvested stock options.

     In the first quarter of 2006, the Company repurchased and retired
     approximately 10 million shares of Company common stock, for cash
     aggregating $324 million. At March 31, 2006, the Company had 19 million
     shares of its common stock remaining under the March 2005 Board of
     Directors repurchase authorization.

M.   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 Company expects that the evaluation, processing
     and payment of claims for both the National Settlement and the Washington
     State Settlement should be completed in 2006.

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

Note M - concluded:

     As previously disclosed, several lawsuits have been brought against the
     Company and a number of its insulation installation companies in the
     federal courts in Atlanta, Georgia, and Ft. Meyers, Florida, alleging that
     certain practices violate provisions of federal and state antitrust laws;
     the complaints are requesting class action certification. The Company is
     vigorously defending these cases and believes that the conduct of the
     Company and its insulation installation companies, which have been the
     subject of these lawsuits, has not violated any antitrust laws.

     As previously disclosed, a lawsuit has been brought against the Company and
     its Milgard Manufacturing subsidiary alleging design defects in certain
     Milgard aluminum windows; the complaint is requesting class action
     certification. The Company is vigorously defending the case and believes
     that its window products have not been manufactured with the alleged design
     defects.

     As previously disclosed, European governmental authorities are
     investigating possible anticompetitive business practices relating to the
     plumbing and heating industries in Europe. The investigations involve a
     number of European companies, including certain of the Company's European
     manufacturing divisions and a number of other large businesses. In
     addition, several private antitrust lawsuits have been filed in the United
     States against the Company and several other companies that are being
     investigated, which appear to be an outgrowth of the European
     investigations. The Company believes that it will not incur material
     liability as a result of the matters that are subject to these
     investigations or as a result of any such lawsuits.

N.   The following is a reconciliation of the Company's warranty liability, in
     millions:

O.   In April 2006, the Company completed the sale of two relatively small
     businesses, the results of which will be included in continuing operations
     through the date of sale; aggregate net sales for these businesses were $46
     million for the year ended December 31, 2005. Cambridge Brass is a supplier
     of plumbing fittings in North America and was included in the Plumbing
     Products segment. Faucet Queens is a supplier of home hardware and repair
     products to food and drug stores in North America and was included in the
     Other Specialty Products segment. Gross proceeds from the sale of these
     businesses was approximately $49 million; total assets and liabilities were
     $52 million and $6 million, respectively, at March 31, 2006. These
     businesses had combined net sales and operating profit of $11 million and
     $1 million, respectively, for the three months ended March 31, 2006.

     In the first quarter of 2006, the Company recognized, in discontinued
     operations, $1 million of additional expenses related to the disposition of
     businesses completed in 2005.

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

P.   As part of the Company's strategy of value creation, the Company announced
     a plant closure in the Plumbing Products segment in January 2006. In the
     first quarter of 2006, the Company incurred $17 million of costs and
     charges (primarily accelerated depreciation and severance expense)
     associated with this plant closure and other profit improvement programs in
     the Plumbing Products segment. The Company expects to incur additional
     costs throughout 2006 and currently anticipates that total costs for the
     full-year will approximate $70 million.

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 performance measures and ratios should be viewed in addition
to, and not as an alternative for, the Company's reported results.

                                    NET SALES

     Net sales in the first quarter of 2006 increased nine percent from the
comparable period in 2005. Excluding results from acquisitions, net sales also
increased nine percent (including a two percent decrease relating to the effect
of currency translation) compared with 2005. 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 nine percent in the
first quarter of 2006 compared with 2005, primarily due to increased sales
volume of assembled cabinets in the new construction and retail markets, offset
in part by a stronger U.S. dollar which had a negative effect on the translation
of local currencies of European operations included in this segment.

     Net sales of Plumbing Products increased five percent in the first quarter
of 2006 compared with 2005, primarily due to increased sales volume through the
Company's wholesale distribution channel, as well as increased sales to certain
retail customers, offset in part by a stronger U.S. dollar which had a negative
effect on the translation of local currencies of European operations included in
this segment.

     Net sales of Installation and Other Services increased 16 percent in the
first quarter of 2006 compared with 2005, primarily due to increased sales
volume of non-insulation products, selling price increases and a continued
strong new-housing market.

     Net sales of Decorative Architectural Products increased 10 percent in the
first quarter of 2006 compared with 2005, primarily due to increased sales
volume and selling price increases of paints and stains.

     Net sales of Other Specialty Products increased five percent in the first
quarter of 2006 compared with 2005, primarily due to increased sales of doors
and windows to North American new construction markets, offset in part by a
stronger U.S. dollar which had a negative effect on the translation of local
currencies of European operations included in this segment.

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

     Net sales from North American and International operations in the first
quarter of 2006 increased 13 percent and decreased five percent, respectively,
compared with the first quarter of 2005. North American sales were positively
affected by increased sales volume of assembled cabinets, paints and stains and
installation services, as well as increased selling prices of paints and stains
and installation services. For the first quarter of 2006, International sales
were negatively affected by a stronger U.S. dollar, principally against the
Euro, which decreased International net sales by eight percent.

                                OPERATING MARGINS

     The Company's gross profit margin was 27.6 percent for the first quarter of
2006 compared with 28.4 percent for the comparable period in 2005. Selling,
general and administrative expenses as a percentage of sales were 16.4 percent
for the first quarter of 2006 and 17.0 percent for the comparable period of the
prior year. First quarter 2006 results were positively affected by increases in
certain selling prices, as well as increased sales volume of assembled cabinets,
paints and stains and installation services, which partially offset commodity
cost increases and a less favorable product mix in certain segments. Operating
profit in 2006 was negatively affected by charges of $17 million related to the
Company's profit improvement programs in the Plumbing Products segment.
Operating profit for the first quarter of 2005 benefited from $2 million of
income regarding the Behr litigation settlement.

     Operating profit margin for the Cabinets and Related Products segment for
the first quarter of 2006 was 14.2 percent compared with 14.8 percent for the
first quarter of 2005, and reflects continued manufacturing and distribution
inefficiencies due to increased demand for assembled cabinets in North America,
as well as a less favorable product mix.

     Operating profit margin for the Plumbing Products segment was 8.3 percent
for the first quarter of 2006 compared with 10.4 percent for the first quarter
of 2005. Operating profit margin in this segment was adversely affected by
charges of $17 million related to the Plumbing Products profit improvement
programs, as well as commodity and freight cost increases and a less favorable
product mix.

     Operating profit margin for the Installation and Other Services segment was
11.8 percent for the first quarter of 2006 compared with 11.5 percent for the
first quarter of 2005. The slight improvement in operating profit margin in this
segment is primarily attributable to selling price increases, offset in part by
increased sales volume of generally lower-margin, non-insulation products.

     Within the Installation and Other Services segment, the availability of
fiberglass insulation to support the Company's installation and distribution
activities continues to be constrained. The high level of demand for fiberglass
insulation as a result of the continued strong new construction market has
outpaced the industry's capacity to produce additional product. The Company
believes that these conditions will persist through 2006 and is working with its
diverse supplier base to secure the appropriate amount of material. At the
current time, the Company believes that it will be able to do so, but if the
Company cannot obtain the required amount of material, this could have a
negative impact on its operations.

     Operating profit margin for the Decorative Architectural Products segment
was 18.8 percent for the first quarter of 2006 compared with 15.9 percent for
the first quarter of 2005. The improvement in operating profit margin is
primarily due to increased selling prices, as well as higher sales volume of
paints and stains which offset commodity cost increases.

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

     Operating profit margin for the Other Specialty Products segment was 14.3
percent for the first quarter of 2006 compared with 14.7 percent for the first
quarter of 2005 and reflects a less favorable product mix.

     The Company's operating profit margin, as reported, was 11.2 percent for
the first quarter of 2006 compared with 11.5 percent for the first quarter of
2005. Operating profit margin for the first quarter of 2006 included the
negative effect of $17 million of charges related to profit improvement programs
in the Plumbing Products segment. Excluding the $17 million of charges in 2006
and the $2 million of income regarding litigation settlement in 2005, operating
profit margin was 11.7 percent and 11.4 percent for the first quarters of 2006
and 2005, respectively.

                           OTHER INCOME (EXPENSE), NET

     Other, net, for the first quarter of 2006 included $5 million of realized
gains, net, from the sale of marketable securities, dividend income of $6
million and $1 million of income from other investments, net. Other, net, also
included currency transaction gains of $4 million for the first quarter of 2006.

     Other, net, for the first quarter of 2005 included $26 million of realized
gains, net from the sale of marketable securities, dividend income of $4 million
and $15 million of income from other investments, net. Other, net, also included
currency transaction losses of $13 million for the first quarter of 2005.

     Interest expense for the first quarter of 2006 increased $5 million to $64
million compared with $59 million for the first quarter of 2005, primarily due
to the issuance of fixed-rate notes in June 2005, as well as the effect of
increasing interest rates.

         INCOME AND EARNINGS PER COMMON SHARE FROM CONTINUING OPERATIONS

     Income and diluted earnings per common share from continuing operations
before the cumulative effect of accounting change, net for the first quarter of
2006 were $208 million and $.51 per common share compared with $207 million and
$.47 per common share for the comparable period of 2005, respectively. The
Company's effective tax rate for the three months ended March 31, 2006 was 34.6
percent compared with 32.3 percent for the same period in 2005. The lower tax
rate for the first quarter of 2005 compared to the first quarter of 2006
resulted primarily from certain adjustments to estimated tax accruals related to
International operations recognized in the first quarter of 2005. The Company
estimates that its effective tax rate for the full-year 2006 should approximate
34 to 35 percent.

                           OTHER FINANCIAL INFORMATION

     The Company's current ratio was 1.3 to 1 and 1.8 to 1 at March 31, 2006 and
December 31, 2005, respectively, due to the reclassification to current
liabilities from long-term debt, $854 million of Zero Coupon Convertible Notes,
as the next put option date is January 20, 2007, and $300 million of
floating-rate notes due March 2007.

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

     For the three months ended March 31, 2006, cash of $31 million was provided
by operating activities. Cash used for financing activities was $1,201 million,
and included $84 million for the payment of cash dividends, $324 million for the
acquisition of Company common stock in open-market transactions and $827 million
(including accrued interest) for the retirement of 6.75% notes due March 15,
2006. Cash provided by financing activities included $7 million from the
issuance of Company common stock, primarily for the exercise of stock options,
and $27 million from the net increase in debt. Net cash used for investing
activities was $113 million, and included $110 million for capital expenditures,
offset in part by $10 million of net proceeds from the sale of financial
investments.

     First quarter 2006 cash from operations was affected by an expected and
annually recurring first quarter increase in accounts receivable and inventories
compared with December 31, 2005.

     Effective January 1, 2006, the Company adopted SFAS No. 123R, "Share-Based
Payment." Note B to the Company's Condensed Consolidated Financial Statements
discusses the accounting policies regarding stock options and awards.

     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
to the Condensed Consolidated Financial Statements discusses specific claims
pending against the Company.

     The Company believes that its present cash balance, 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

     In late 2005 and into 2006, the Company has experienced additional
commodity cost increases; the Company believes such increases will adversely
affect its 2006 operating performance. The Company has already implemented and
continues to implement additional price increases for a number of its products,
and believes that by the end of the first half of 2006, many of these cost
increases will be largely offset by such price increases.

     The Company remains committed to its strategy of value creation and is
focused on the simplification of its business model, cash flow generation,
improvement in return on invested capital and the return of cash to shareholders
through share repurchases and dividends.

     Consistent with this strategy, the Company is pursuing a variety of
initiatives to offset cost increases and increase operating profit, including
sourcing programs, the restructuring of certain of its businesses (including
consolidations), manufacturing rationalization, headcount reductions and other
profit improvement programs.

     As part of its strategy of value creation, the Company announced a plant
closure in the Plumbing Products segment in January 2006. The Company incurred
$17 million of costs associated with this plant closure and other profit
improvement programs in the first quarter of 2006 and expects to incur
additional costs throughout 2006. Implementing these initiatives should improve
the Company's earnings outlook for 2007 and beyond.
