                                MASCO CORPORATION
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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 June 30, 1998 and the results of operations for the three months and
        six months ended June 30, 1998 and 1997 and cash flows for the six
        months ended June 30, 1998 and 1997. The condensed consolidated balance
        sheet at December 31, 1997 was derived from audited financial
        statements. Shares and per share data have been adjusted to reflect the
        July 1998 100 percent stock distribution to shareholders and to conform
        with the earnings per share presentation required under Statement of
        Financial Accounting Standards ("SFAS") No. 128. Certain amounts for the
        prior year periods have been reclassified to conform to the current year
        presentation.

B.      The following are reconciliations of the numerators and denominators
        used in the computations of basic and diluted earnings per share, in
        thousands:

      Denominator:

           average)                           333,500    316,000    331,100    316,000

           Convertible debentures                 ---      8,400      1,900      8,400
         Diluted shares                       344,200    333,600    343,800    333,400


        Diluted earnings per share in the first and second quarters of 1997 were
        $.26 and $.28, respectively, which when totaled equal $.54. Based on the
        above reconciliation for the six months ended June 30, 1997, however,
        diluted earnings per share approximates $.535.

C.      During June 1998, the Company's Board of Directors adopted a resolution
        for a stock split, effected in the form of a 100 percent stock
        distribution (one additional share for every share held) to shareholders
        of record on June 19, 1998 to be issued on July 10, 1998. Following the
        issuance of the common shares for the stock split, the Company declared
        an increased quarterly dividend of $.11 per common share on its
        post-split shares. Such dividend is the equivalent of $.22 per share
        quarterly prior to the stock split. The Company had been previously
        paying a $.21 per share quarterly dividend on its pre-split shares.

D.      During the second quarter of 1998, the Company acquired General
        Accessory Manufacturing Company, a manufacturer of stainless steel
        commercial washroom accessories and bathroom partitions, and Mirolin
        Industries, Inc., a Canadian manufacturer of tubs, shower enclosures and
        whirlpools. During the first quarter of 1998, the Company acquired Vasco
        Corporation, a Belgium-based manufacturer of residential decorative
        hydronic radiators and heat convectors. The aggregate net purchase price
        of these acquisitions was approximately $189 million and was principally
        financed with bank debt.

        In July 1998, the Company acquired The Brugman Group, a European
        manufacturer of residential hydronic radiators and heat convectors.

        The above acquisitions were accounted for as purchase transactions.
        Combined 1997 annual net sales of companies acquired in 1998 through
        July were approximately $150 million.

        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)


E.      In July 1998, the Company completed the sale of its Thermador
        subsidiary. Thermador is a U.S. manufacturer of kitchen appliances, with
        annualized 1998 net sales of approximately $140 million. The 1998 third
        quarter is expected to include a modest pre-tax gain, net from the sale.

F.      The Company called for redemption its $178 million of 5.25% convertible
        subordinated debentures due 2012 on February 12, 1998. Substantially all
        holders exercised their right to convert these debentures into Company
        common stock (at the conversion price of $21.14 per share), resulting in
        the issuance of approximately 8.4 million shares of Company common stock
        in February 1998.

        During the first quarter of 1998, the Company retired approximately $98
        million face value of its outstanding 9% debentures due 2001 (of a total
        face value of $175 million at December 31, 1997), using a portion of its
        available cash. The Company recognized an approximate $12 million
        pre-tax charge related to the early retirement of long-term debt.

        During the second quarter of 1998, the Company issued $250 million of
        6.625% debentures due April 2018.

G. Other income (expense), net consists of the following, in thousands:

        Included in other, net for the six months ended June 30, 1998 is a $29
        million pre- tax gain from the sale of the Company's investment in
        TriMas Corporation to MascoTech, Inc. in the public tender offer. Such
        gain was largely offset by an approximate $12 million pre-tax charge
        related to the early retirement of long-term debt, and by pre-tax
        charges aggregating approximately $11 million principally related to
        certain asset writedowns.

        Other, net for the three months and six months ended June 30, 1998
        includes income and gains, net regarding certain non-operating assets of
        $16.0 million and $26.4 million, respectively, as compared with $7.4
        million and $12.4 million of such income and gains, net for the
        comparable periods of the prior year.

        Included in other interest income for the three months and six months
        ended June 30, 1998 and 1997 is interest income of approximately $10.1
        million and $20.2 million and approximately $9.0 million and $18.0
        million, respectively, from the 12% pay-in- kind junior debt securities
        of Furnishings International Inc. (approximately $336 million principal
        amount at December 31, 1997).

        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)


NOTE G - CONTINUED:

        In late June 1997, MascoTech, Inc., an equity affiliate, redeemed all of
        its outstanding convertible preferred stock in exchange for
        approximately 10 million shares of its common stock. This redemption
        reduced the Company's common equity ownership in MascoTech to 17 percent
        from 21 percent, and increased the Company's equity in MascoTech's net
        book value by approximately $29.5 million. As a result, the Company
        recognized a pre-tax gain of approximately $29.5 million during the
        second quarter of 1997.

        Other, net in the second quarter of 1997 includes charges aggregating
        $29.5 million, which offset the above-mentioned MascoTech gain,
        primarily for the adjustment of the Company's Payless Cashways
        investment to its estimated fair value.

        During the first half of 1997, the Company recognized interest income at
        6.625% on the $151.4 million receivable balance due from MascoTech.

H.      The Company adopted Statement of Financial Accounting Standards ("SFAS")
        No. 130, "Reporting Comprehensive Income," in the first quarter of 1998.
        Accordingly, the Company's total comprehensive income was as follows, in
        thousands:

I.      On June 15, 1998, the Financial Accounting Standards Board issued
        Statement of Financial Accounting Standards ("SFAS") No. 133,
        "Accounting for Derivative Instruments and Hedging Activities." SFAS 133
        is effective for all fiscal quarters of all fiscal years beginning after
        June 15, 1999 (January 1, 2000 for the Company). SFAS 133 requires that
        all derivative instruments be recorded on the balance sheet at their
        fair value. Changes in the fair value of derivatives are recorded each
        period in current earnings or other comprehensive income, depending on
        whether a derivative is designated as part of a hedge transaction and,
        if it is, the type of hedge transaction. The Company anticipates that
        the adoption of SFAS 133 will not have a significant effect on the
        Company's results of operations or its financial position.

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

SECOND QUARTER 1998 AND THE FIRST SIX MONTHS 1998 VERSUS
SECOND QUARTER 1997 AND THE FIRST SIX MONTHS 1997

                              SALES AND OPERATIONS

        Net sales increased 19 percent and 20 percent for the three months and
six months ended June 30, 1998, respectively, from the comparable periods in
1997. Excluding acquisition of companies during 1998 and 1997, net sales for the
three months and six months ended June 30, 1998 increased 9 percent and 10
percent, respectively, from the comparable periods in 1997; these increases in
net sales are principally due to increases in unit sales volume of cabinets,
other kitchen and bath products and faucets.

        Sales of Kitchen and Bath Products for the three months and six months
ended June 30, 1998 were $841 million and $1,654 million, respectively,
representing increases of 18 percent and 19 percent, respectively, from the
comparable periods in 1997; excluding acquisition of companies, net sales of
this segment increased 9 percent and 10 percent, respectively for the three
months and six months ended June 30, 1998.

        Sales of Other Specialty Products for the three months and six months
ended June 30, 1998 were $244 million and $470 million, respectively,
representing increases of 21 percent and 25 percent, respectively, from the
comparable periods in 1997; excluding acquisition of companies, net sales of
this segment increased 6 percent and 9 percent, respectively, for the three
months and six months ended June 30, 1998.

        Net sales from North American operations for the second quarter and six
months ended June 30, 1998 were $887 million and $1,744 million, respectively,
representing increases of 17 percent and 18 percent, respectively, from the
comparable periods in 1997; excluding acquisition of companies, net sales from
these operations increased 10 percent and 11 percent, respectively, from the
comparable periods in 1997. Net sales from European operations for the second
quarter and six months ended June 30, 1998 were $198 million and $380 million,
respectively, representing increases of 30 percent, from the comparable periods
in 1997; excluding acquisition of companies, net sales from these operations
were flat when compared with the prior year periods. A stronger U.S. dollar,
principally against the German Deutsche Mark, had a negative effect on the
translation of European sales in the first half of 1998, as compared with the
first half of 1997; excluding acquisition of companies, European net sales for
the second quarter and six months ended June 30, 1998 in local currencies
increased by approximately 10 percent.

        The Company's operating profit margins improved in the second quarter
and first half of 1998 from the comparable 1997 periods. Cost of sales as a
percentage of sales increased slightly to 63.7 percent from 63.3 percent and to
63.6 percent from 63.3 percent for the second quarter and six months ended June
30, 1998, respectively, from the comparable periods in 1997; selling, general
and administrative expenses as a percentage of sales decreased to 19.7 percent
from 20.5 percent and to 19.8 percent from 20.8 percent for the second quarter
and six months ended June 30, 1998, respectively, from the comparable periods in
1997. The decrease in the selling, general and administrative expenses
percentage in 1998 includes the Company's cost-control initiatives and the
leveraging of fixed costs over a higher sales base. The Company's operating
profit margins, before general corporate expense, were 18.0 percent for both the
second quarter and six months ended June 30, 1998, respectively, as compared
with 18.0 percent and 17.8 percent for the comparable 1997 periods. Operating
profit margins, after general corporate expense, were 16.0 percent for both the
second quarter and six months ended June 30, 1998, as compared with 15.8 percent
and 15.5 percent for the comparable 1997 periods.

            FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

                           OTHER INCOME (EXPENSE), NET

        Included in other income (expense), net for the second quarter and six
months ended June 30, 1998 were equity earnings from MascoTech, Inc. of $5.1
million and $10.3 million, respectively, as compared with equity earnings of
$4.3 million and $10.3 million for the comparable periods of the prior year.

        Included in other, net for the six months ended June 30, 1998 is a $29
million pre-tax gain from the sale of the Company's investment in TriMas
Corporation to MascoTech, Inc. in the public tender offer. Such gain was largely
offset by an approximate $12 million pre-tax charge related to the early
retirement of long-term debt, and by pre-tax charges aggregating approximately
$11 million principally related to certain asset writedowns.

        Other, net for the three months and six months ended June 30, 1998
includes income and gains, net regarding certain non-operating assets of $16.0
million and $26.4 million, respectively, as compared with $7.4 million and $12.4
million of such income and gains, net for the comparable periods of the prior
year.

        Included in other interest income for the three months and six months
ended June 30, 1998 and 1997 is interest income of approximately $10.1 million
and $20.2 million and approximately $9.0 million and $18.0 million,
respectively, from the 12% pay-in-kind junior debt securities of Furnishings
International Inc. (approximately $336 million principal amount at December 31,
1997).

        In late June 1997, MascoTech redeemed all of its outstanding convertible
preferred stock in exchange for approximately 10 million shares of its common
stock. This redemption reduced the Company's common equity ownership in
MascoTech to 17 percent from 21 percent, and increased the Company's equity in
MascoTech's net book value by approximately $29.5 million. As a result, the
Company recognized a pre-tax gain of approximately $29.5 million during the
second quarter of 1997.

        Other, net in the second quarter of 1997 includes charges aggregating
$29.5 million, which offset the above-mentioned MascoTech gain, primarily for
the adjustment of the Company's Payless Cashways investment to its estimated
fair value.

        Included in other income (expense), net for the three months and six
months ended June 30, 1997 is $2.5 million and $5.0 million, respectively, of
interest income from the $151.4 million receivable balance due from MascoTech.

Item 2.              MANAGEMENT'S DISCUSSION AND ANALYSIS OF
            FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)


                        NET INCOME AND EARNINGS PER SHARE

        Net income for the second quarter of 1998 increased 28 percent to $117
million from $91.6 million in the comparable 1997 period. Basic and diluted
earnings per share for the second quarter of 1998 each increased 21 percent, to
$.35 and $.34 from $.29 and $.28, respectively, for the comparable period of
1997.

        Net income for the six months ended June 30, 1998 increased 30 percent
to $227.6 million from $175.1 million in the comparable 1997 period. Basic and
diluted earnings per share for the six months ended June 30, 1998 increased 25
percent and 22 percent, respectively, to $.69 and $.66 from $.55 and $.54,
respectively, for the comparable period of 1997.

        The Company's effective tax rate for the three months and six months
ended June 30, 1998 was 38.0 percent and 39.0 percent, respectively, as compared
with 39.9 percent and 40.0 percent for the comparable periods of the prior year.
The reduction in the Company's effective tax rate is principally due to the
improved utilization of foreign tax credits and the utilization of a portion of
the Company's capital loss carryforward benefit. The Company estimates that its
effective tax rate for 1998 will approximate 39.0 percent.

                           OTHER FINANCIAL INFORMATION

        During June 1998, the Company's Board of Directors adopted a resolution
for a stock split, effected in the form of a 100 percent stock distribution (one
additional share for every share held) to shareholders of record on June 19,
1998 to be issued on July 10, 1998. Following the issuance of the common shares
for the stock-split, the Company declared an increased quarterly dividend of
$.11 per common share on its post-split shares. Such dividend is the equivalent
of $.22 per share quarterly prior to the stock split. The Company had been
previously paying a $.21 per share quarterly dividend on its pre-split shares.

        At June 30, 1998, current assets were 3.2 times current liabilities.

        For the six months ended June 30, 1998, cash of $106.1 million was
provided by operating activities. Cash used for investing activities was $266.4
million, including $189.4 million for acquisition of companies, $74.6 million
for capital expenditures and $57.0 million for other cash outflows; cash from
investing activities included $54.6 million from the sale of the Company's
TriMas investment. Financing activities provided cash of $135.6 million,
including $250 million from the issuance of 6.625% debentures and an increase in
debt of $131.3 million (primarily European bank debt for an acquisition); cash
used for financing activities included $108.6 million for the early retirement
of certain of the Company's 9% notes and the payment of a premium associated
with this early retirement, $66.6 million for the payment of debt and $70.5
million for cash dividends paid. The aggregate of the preceding items represents
a net cash outflow of $24.7 million. Changes in working capital and debt as
indicated on the statement of cash flows exclude the effect of acquisition of
companies, other than as mentioned above.

Item 2.              MANAGEMENT'S DISCUSSION AND ANALYSIS OF
            FINANCIAL CONDITION AND RESULTS OF OPERATIONS (concluded)


        First and second quarter 1998 cash from operations was affected by an
expected and recurring first-half increase in accounts receivable. As the annual
increase in accounts receivable is historically experienced in the first half of
the year, cash flows from operations in the remaining two quarters of 1998 are
not expected to be affected by significant increases in accounts receivable.

        The Company called for redemption its $178 million of 5.25% convertible
subordinated debentures due 2012 on February 12, 1998. Substantially all holders
exercised their right to convert these debentures into Company common stock (at
the conversion price of $21.14 per share), resulting in the issuance of
approximately 8.4 million shares of Company common stock in February 1998.

        The Company has on file with the Securities and Exchange Commission, an
unallocated shelf registration pursuant to which the Company is able to issue up
to a combined $509 million of debt and equity securities.

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

Item 1.       Legal Proceedings

              During the second quarter of 1998, a subsidiary of the Company was
              issued a proposed civil penalty in excess of $100,000 by a county
              wastewater agency for alleged past exceedances of wastewater
              discharge limitations. The subsidiary and the agency are in the
              process of finalizing a consent decree to resolve this matter, and
              the costs of any penalties will be immaterial to the Company. The
              subsidiary is now in compliance with all applicable wastewater
              discharge requirements.

Items 2 & 3 are not applicable.

Item 4.       Submission of Matters to a Vote of Security Holders

              The Annual Meeting of Stockholders was held on May 20, 1998 at
