ITEM 1. BUSINESS.
 
     Masco Corporation is engaged principally in the manufacture, sale and
installation of home improvement and building products. Masco believes that it
is the largest domestic manufacturer of faucets, kitchen and bath cabinets and
plumbing supplies and that it is a leading domestic producer of a number of
other home improvement and building products. Masco was incorporated under the
laws of Michigan in 1929 and in 1968 was reincorporated under the laws of
Delaware. Except as the context otherwise indicates, the terms "Masco" and the
"Company" refer to Masco Corporation and its consolidated subsidiaries.
 
     The Company is among the country's largest manufacturers of brand name
consumer products designed for the home improvement and home building
industries. In addition to faucets, kitchen and bath cabinets and plumbing
supplies, the Company manufactures and sells kitchen appliances, bath and shower
enclosure units, spas and hot tubs, other shower, bath and plumbing specialties
and accessories, door locks and other builders' hardware, air treatment
products, venting and ventilating equipment and water pumps. These products are
sold through mass merchandisers, home centers, hardware stores, distributors,
wholesalers and other outlets to consumers and contractors. The Company also
supplies and installs insulation and other building products direct to builders
and consumers. The Company's operations are categorized into two industry
segments: Kitchen and Bath Products and Other Specialty Products.
 
                               INDUSTRY SEGMENTS
 
     The following table sets forth for the three years ended December 31, 1997,

    Company's Consolidated Financial Statements captioned "Discontinued
    Operations," included in Item 8 of this Report.
 
(2) Amounts are before general corporate expense.
 
     Additional financial information concerning the Company's operations by
industry segments as of and for the three years ended December 31, 1997 is set
forth in the Note to the Company's Consolidated Financial Statements captioned
"Segment Information," included in Item 8 of this Report.
 
KITCHEN AND BATH PRODUCTS
 
     The Company manufactures a variety of single and double handle faucets.
DELTA(R) and PEERLESS(R) single and double handle faucets are used on kitchen,
lavatory and other sinks and in bath and shower installations. DELTA faucets are
sold through manufacturers' representatives to major
                                        2
<PAGE>   4
 
retail accounts and to distributors who sell the faucets to plumbers, building
contractors, remodelers, smaller retailers and others. PEERLESS faucets are sold
primarily through manufacturers' representatives directly to retail outlets such
as mass merchandisers, home centers and hardware stores and are also sold under
private label. The Company's ARTISTIC BRASS(R) faucets and accessories are
produced for the decorator markets and are sold through wholesalers, distributor
showrooms and other outlets. ALSONS(R) hand showers and shower heads and
MIXET(R) valves and accessories are distributed through manufacturers'
representatives to the wholesale market and to retailers.
 
     Sales of faucets worldwide approximated $815 million in 1997, $757 million
in 1996 and $698 million in 1995. The percentage of operating profit on faucets
is somewhat higher than that on other products offered by the Company. The
Company believes that the simplicity, quality and reliability of its faucet
mechanisms, manufacturing efficiencies and capabilities, its marketing and
merchandising activities, and the development of a broad line of products have
accounted for the continued strength of its faucet sales. Management believes
that Masco's faucet operations hold a leadership position in the United States
market. The faucet market in the United States is very competitive, with Moen,
Price Pfister, Sterling and American Standard as major brand competitors.
Competition from import products is also a factor in the Company's markets.
 
     The Company manufactures economy, stock, semi-custom and custom kitchen and
bath cabinetry in a variety of styles and in various price ranges. The Company
sells cabinets under a number of trademarks, including MERILLAT(R),
KRAFTMAID(R), QUALITY CABINETS(R), STARMARK(R) and FIELDSTONE(R), with sales to
distributors, home centers, dealers and direct to builders for both the home
improvement and new construction markets. In addition to its domestic
manufacturing, the Company manufactures cabinetry in Germany, where sales are
made primarily through Company-owned showrooms to consumers, and in England,
with sales primarily to builders for the new construction market. Sales of
kitchen and bath cabinets were approximately $1,083 million in 1997, $832
million in 1996 and $758 million in 1995. During 1997, the Company acquired
Texwood Industries, Inc., a domestic manufacturer of kitchen and bath cabinetry.
Management believes that the Company is the largest manufacturer of kitchen and
bath cabinetry in the United States. Significant competitors are American
Woodmark Corporation, Aristokraft, Inc., WCI Group and Triangle Pacific
Corporation.
 
     The Company's brass and copper plumbing system components and other
plumbing specialties are sold to plumbing, heating and hardware wholesalers and
to home centers, hardware stores, building supply outlets and other mass
merchandisers. These products are marketed for the wholesale trade under the
BRASSCRAFT(R) trademark and for the "do-it-yourself" market under the PLUMB
SHOP(R), HOME PLUMBER(R) and MELARD(TM) trademarks and are also sold under
private label.
 
     Other Kitchen and Bath Products sold by the Company include THERMADOR(R)
cooktops, ovens, ranges and related cooking equipment and refrigerators, which
are marketed through appliance distributors and dealers. The Company's AQUA
GLASS(R) acrylic and gelcoat bath and shower units and whirlpools are sold
primarily to wholesale plumbing distributors for use in the home improvement and
new home construction markets. Other bath and shower enclosure units, shower
trays and laundry tubs are sold to the home improvement market through hardware
stores and home centers under the brand names AMERICAN SHOWER & BATH(TM) and
TRAYCO(TM). HUPPE(R) luxury bath and shower enclosures are manufactured and sold
by the Company through wholesale channels primarily in Germany. The Company
manufactures bath and shower accessories, vanity mirrors and bath storage
products and sells these products under the brand name ZENITH PRODUCTS(R) and
other trademarks to home centers, hardware stores and mass merchandisers for the
"do-it-yourself" market. The Company's spas and hot tubs are sold under the
brand name HOT SPRING SPA(R) and other trademarks directly to retailers for sale
to residential customers. In early 1997, the Company acquired Franklin Brass
Manufacturing Company, a leading manufacturer of bath accessories and bath
safety products.
 
     Direct sales to home center retailers in all of the Company's product lines
have been increasing in recent years, and in 1997 sales to The Home Depot were
$392 million, approximately 10 percent of the
 
                                        3
<PAGE>   5
 
Company's 1997 sales volume. Builders, distributors, wholesalers and other
retailers represent other channels of distribution for the Company's products.
 
OTHER SPECIALTY PRODUCTS
 
     The Company's Other Specialty Products include premium BALDWIN(R) quality
brass trim and mortise lock sets, knobs and trim and other builders' hardware
which are manufactured and sold for the home improvement and new home
construction markets. WEISER(R) lock sets and related hardware are sold through
contractor supply outlets, hardware distributors and home centers. SAFLOK(TM)
electronic lock sets and WINFIELD(TM) mechanical lock sets are sold primarily to
the hospitality market. During 1997, the Company acquired LaGard Inc., whose
electronic lock sets are used primarily by the banking industry on safes, ATMs,
vaults and cabinetry, and Liberty Hardware Manufacturing Corporation, a producer
of quality cabinet and builders' hardware. Key domestic competitors to Baldwin
and Weiser in the lock set business are Black & Decker Corporation and Schlage
Lock Company. Imported products are also becoming a major factor in this market.
 
     The Company has recently begun to incorporate on many of its decorative
brass faucets and other products a durable coating that offers anti-tarnish
protection, under the trademarks BRILLIANCE(R) and THE LIFETIME FINISH FROM
BALDWIN(R). This innovative finish is currently available on certain of the
Company's kitchen and bath products and door hardware.
 
     The Company manufactures ventilation products under the trademark AMP(R),
including grilles, registers, diffusers and humidifiers which are sold through
wholesale distribution and home centers. GEBHARDT(TM) commercial ventilating
products and JUNG(TM) water pumps are manufactured and distributed by the
Company in Europe. Through local offices of Gale Industries, Inc. in various
parts of the United States, the Company also supplies and installs insulation
and other building products primarily for the residential home building
industry.
 
COMPETITIVE FACTORS
 
     The major domestic and foreign markets for the Company's products are
highly competitive. Competition in all of the Company's product lines is based
primarily on performance, quality, style, delivery, customer service and price,
with the relative importance of such factors varying among products. A number of
companies of varying size compete with one or more of the Company's product
lines.
 
GENERAL INFORMATION
 
     No material portion of the Company's business is seasonal or has special
working capital requirements, although the Company maintains a higher investment
in inventories for certain of its businesses than the average manufacturing
company. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Cash Flows from Operating Activities," included in Item
7 of this Report. The Company does not consider backlog orders to be material
and no material portion of its business is subject to renegotiation of profits
or termination of contracts at the election of the federal government.
Compliance with federal, state and local regulations relating to the discharge
of materials into the environment, or otherwise relating to the protection of
the environment, is not expected to result in material capital expenditures by
the Company or to have a material effect on the Company's earnings or
competitive position. In general, raw materials required by the Company are
obtainable from various sources and in the quantities desired.
 
INTERNATIONAL OPERATIONS
 
     Through its subsidiaries, the Company also has home improvement and
building products manufacturing plants in Austria, Belgium, Canada, Denmark,
England, France, Germany, Italy, Mexico, Poland, Spain, Taiwan and Turkey. Home
improvement and building products manufactured by the Company outside of the
United States include faucets and accessory products, bath and shower
                                        4
<PAGE>   6
 
enclosures, bath accessories, kitchen and bath cabinets, decorative accessories,
door lock sets and related hardware, floor registers, humidifiers, ventilating
equipment, submersible water pumps and special insulation materials. The
Company's European operations were expanded through the recent acquisition of
three manufacturers. In 1997, the Company acquired The SKS Group, a leading
German manufacturer and distributor of roller shutters and aluminum balcony
railings, and The Alvic Group, a leading Spanish manufacturer and distributor of
kitchen and bath cabinetry and components. In early 1998, the Company acquired
Vasco Corporation, a leading European manufacturer of residential decorative
hydronic radiators and heat convectors, based in Belgium.
 
     The Company's foreign operations are subject to political, monetary,
economic and other risks attendant generally to international businesses. These
risks generally vary from country to country. Financial information concerning
the Company's export sales and foreign and domestic operations, including the
net sales, operating profit and assets which are attributable to the Company's
operations in North America and in other geographic areas, as of and for the
three years ended December 31, 1997, is set forth in Item 8 of this Report in
the Note to the Company's Consolidated Financial Statements captioned "Segment
Information."
 
PATENTS AND TRADEMARKS
 
     The Company holds a number of United States and foreign patents covering
various design features and valve constructions used in certain of its faucets,
and also holds a number of other patents and patent applications, licenses,
trademarks and tradenames. As a manufacturer of brand name consumer products,
the Company views its trademarks and other proprietary rights as important, but
does not believe that there is any reasonable likelihood of a loss of such
rights that would have a material adverse effect on the Company's present
business as a whole.
 
EMPLOYEES
 
     At December 31, 1997, the Company employed approximately 28,100 people.
Satisfactory relations have generally prevailed between the Company and its
employees.
 
EQUITY INVESTMENTS
 
     Information about the Company's equity investments is also set forth in the
Note to the Company's Consolidated Financial Statements captioned "Equity
Investments in Affiliates" included in Item 8 of this Report.
 
     MascoTech, Inc.
 
     In 1984, the Company transferred its industrial businesses to a newly
formed subsidiary, MascoTech, Inc. (formerly Masco Industries, Inc.), which
became a separate public company in July, 1984 when the Company distributed to
its stockholders certain shares of MascoTech common stock as a special dividend.
In October 1996, the Company reduced its common equity interest in MascoTech
from 45 percent to 21 percent through the sale to MascoTech of MascoTech common
stock and warrants to purchase shares of MascoTech common stock for total
consideration of approximately $266 million. Payment of $115 million of the
purchase price was made in cash at closing and the balance of approximately $151
million was paid by MascoTech on September 30, 1997, in accordance with its
agreement, in the form of 9.9 million shares (approximately 42%) of the
outstanding common stock of Emco Limited and $45.6 million in cash. As part of
that transaction, the Company granted MascoTech a right of first refusal, which
expires September 30, 2000, to purchase the remaining shares of MascoTech common
stock held by the Company. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations," included in Item 7 of this
Report, regarding the effect of this transaction on the Company. Emco is a
Canadian manufacturer and distributor of home improvement and building products.
See the discussion of "Emco Limited" below. MascoTech's conversion of its
 
                                        5
<PAGE>   7
 
outstanding preferred stock into MascoTech common stock in mid-1997 further
reduced the Company's ownership in MascoTech to approximately 17 percent.
 
     MascoTech is a leading supplier of metalworked components primarily for
vehicle engine and drivetrain applications and automotive aftermarket products
for the transportation industry. MascoTech's net sales for 1997 were
approximately $922 million. Approximately 72 percent of MascoTech's
transportation-related products sales in 1997 were original equipment automotive
products and services.
 
     In January 1998, MascoTech acquired the remaining 63 percent of TriMas
Corporation that it did not previously own, including approximately 1.6 million
shares (4%) owned by the Company, for approximately $920 million. TriMas is a
diversified proprietary products company with leadership positions in
commercial, industrial and consumer niche markets. TriMas had sales of
approximately $668 million and net income of approximately $66 million for the
twelve months ended December 31, 1997.
 
     TriMas' products include specialty fasteners, towing systems, specialty
container products and other industrial products.
 
     Emco Limited
 
     The Company owns approximately 42 percent of the outstanding common stock
of Emco Limited, as a result of the transactions described above under "Equity
Investments -- MascoTech, Inc." Emco is a leading Canadian distributor and
manufacturer of building products for the residential, commercial and industrial
construction markets, including roofing materials, wood fiber products and
sinks, and a distributor of plumbing and related products. Emco had sales of CDN
$1.26 billion for the twelve months ended December 31, 1997.
 
     Hans Grohe
 
     The Company has a 27 percent partnership interest in Hans Grohe GmbH & Co.
KG, a German manufacturer of faucets, handheld showers, shower heads, shower
cabins and other shower accessories.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
     The financial and business analysis below provides information which the
Company believes is relevant to an assessment and understanding of the Company's
consolidated financial position and results of operations. This financial and
business analysis should be read in conjunction with the consolidated financial
statements and related notes.
 
     The following discussion and other sections of this Report on Form 10-K
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 may cause the Company's actual results to differ
materially from the results discussed in such forward-looking statements.
Readers should consider that various factors including those discussed in the
"Overview" and "Outlook for the Company" sections below may affect the Company's
ability to attain the projected performance. The Company undertakes no
obligation to update publicly any forward-looking statements, whether as a
result of new information, future events or otherwise.
 
OVERVIEW
 
     The Company is engaged principally in the manufacture, sale and
installation of home improvement and building products. These products are sold
to the home improvement and home construction markets through mass
merchandisers, home centers, hardware stores, distributors, wholesalers and
other outlets for consumers and contractors.
 
     Factors which affect the Company's results of operations include the levels
of home improvement and residential construction activity principally in the
U.S. and Europe (including repair and remodeling and new construction), cost
management, fluctuations in European currencies (primarily the German Deutsche
Mark and British Pound), the increasing importance of home centers as
distributors of home improvement and building products and the Company's ability
to maintain its leadership positions in its markets with increasing global
competition. Historically, the Company has been able to largely offset cyclical
declines in housing markets through new product introductions and acquisitions
as well as market share gains.
 
     Net sales and operating profit from continuing operations for 1997 were
$3,760 million and $587 million, representing increases of 16 percent and 22
percent, respectively, over 1996. Net income from continuing operations for 1997
was $382 million representing an increase of 30 percent over 1996. Basic and
diluted earnings per share for 1997 were $2.39 and $2.30, respectively,
representing increases of 28 percent and 26 percent, respectively, over 1996
amounts. Increases in net sales typically result in operating profit
improvements that exceed the net sales increases on a percentage basis due to
the allocation of fixed and semi-fixed costs and expenses over a higher sales
base.
 
CORPORATE DEVELOPMENT
 
     Acquisitions have historically contributed significantly to Masco's
long-term growth, even though generally the initial impact on earnings is
minimal after deducting acquisition-related costs and expenses such as interest
and added depreciation and amortization. The important earnings benefit to Masco
arises from subsequent growth of acquired companies, since incremental sales are
not handicapped by these expenses.
 
     During 1997, the Company acquired Texwood Industries, Inc., a U.S.
manufacturer of kitchen and bath cabinetry, and five other home improvement and
building products companies, including two companies in Europe.
 
     The results of operations for these acquisitions are included in the
consolidated financial statements from the dates of acquisition. Had these
companies been acquired effective January 1, 1996, pro forma unaudited
consolidated net sales and net income would have approximated $3,909 million and
$390 million for 1997 and $3,575 million and $309 million for 1996,
respectively, and pro forma
                                       11
<PAGE>   13
 
unaudited consolidated diluted earnings per share would have approximated $2.33
and $1.87 for 1997 and 1996, respectively.
 
     The combined purchase price for these acquisitions, including assumed debt,
aggregated approximately $430 million and included approximately 2.9 million
shares of Company common stock valued at approximately $119 million, with the
balance in cash and a short-term note. The acquisitions were accounted for as
purchase transactions.
 
DISCONTINUED OPERATIONS
 
     In late November 1995, the Company's Board of Directors approved a formal
plan to dispose of the Company's home furnishings products segment. An aggregate
provision of $650 million was recorded in the fourth quarter of 1995 for the
estimated loss on the discontinued operations through the expected disposal
date, the reduction of assets to their estimated net realizable value and the
anticipated liabilities related to the disposal. The majority of the charge from
the disposition of the home furnishings products segment resulted in a capital
loss for tax purposes. The ultimate tax benefit from the disposition cannot be
determined currently and is reported if and when taxable capital gains are
realized.
 
     During August 1996, the Company completed the sale of its home furnishings
products segment to Furnishings International Inc. Total proceeds to the Company
from the sale were $1,050 million with approximately $708 million of the
purchase price in cash. The balance consisted of $285 million of 12 percent
pay-in-kind junior debt securities, and equity securities totalling $57 million,
consisting of 13 percent cumulative preferred stock, with a stated value of $55
million, 15 percent of the common stock of Furnishings International and
convertible preferred stock.
 
     The junior debt securities mature in 2008; the Company is recording the 12
percent pay-in-kind interest income from these securities. The Company records
dividend income from the 13 percent cumulative preferred stock when such
dividends are declared. The convertible preferred stock represents transferable
rights for up to a 25 percent common ownership, although the Company is
restricted from maintaining an ownership in excess of 20 percent of Furnishings
International's common equity. As such, the Company will not acquire additional
common equity, except for purposes of resale only. Of the cash proceeds received
from this sale, approximately $550 million was applied to reduce bank debt.
 
     Under a transitional services agreement, the Company provided
corporate-related services for a fee to Furnishings International through April
1997. Substantially all of these services were discontinued after such date.
 
PROFIT MARGINS
 
     Operating profit margin, before general corporate expense, improved to 17.8
percent in 1997 from 17.5 percent in 1996 and 16.8 percent in 1995 (general
corporate expense includes those expenses not specifically attributable to the
Company's business segments). The improvement in 1997 is principally due to a
reduction in selling, general and administrative expenses as a percentage of
sales. The Company's operating margin from faucet sales is somewhat higher than
that on other products offered by the Company due to the simplicity, quality and
reliability of its faucet mechanisms, manufacturing efficiencies and
capabilities, extensive marketing and merchandising activities and breadth of
product offering.
 
     General corporate expense in 1997 was $82 million, as compared with $85
million in 1996 and $90 million in 1995. General corporate expense as a
percentage of sales decreased to 2.2 percent in 1997 from 2.6 percent in 1996
and 3.1 percent in 1995. Operating profit margin, after general corporate
expense, was 15.6 percent, 14.8 percent and 13.7 percent in 1997, 1996 and 1995,
respectively.
 
     Net income from continuing operations as a percentage of sales increased to
10.2 percent in 1997 from 9.1 percent and 6.8 percent in 1996 and 1995,
respectively. After-tax profit return on shareholders'
                                       12
<PAGE>   14
 
equity as measured by net income from continuing operations increased to 20.8
percent in 1997 from 17.8 percent and 9.4 percent in 1996 and 1995,
respectively.

     Over the years, the Company has largely funded its growth through cash
provided by a combination of operations and long-term bank and other borrowings,
and by the issuance of common stock for certain acquisitions. At December 31,
1997, the Company's shelf-registration statement permits the issuance of up to a
combined $759 million of debt and equity securities.
 
     Bank credit lines are maintained to ensure availability of short-term funds
on an as-needed basis. At December 31, 1997, the Company had available $750
million under its bank revolving-credit facility. Any outstanding balances under
this facility are due and payable in November 2001. Certain debt agreements
contain limitations on additional borrowings and requirements for maintaining a
certain level of tangible net worth. At December 31, 1997, the Company was in
compliance with these limitations and requirements, and the Company's tangible
net worth exceeded the most restrictive of such provisions by approximately $171
million.
 
     Maintaining high levels of liquidity and cash flow are among the Company's
financial strategies. The Company's long-term debt as a percent of total
capitalization ratio improved to approximately 36 percent at December 31, 1997
from approximately 39 percent at December 31, 1996. (On a pro forma basis, the
Company's long-term debt as a percent of total capitalization ratio would have
been approximately 32 percent, assuming conversion of the Company's $178 million
of convertible debentures; this conversion was completed in February 1998.)
Aggregate short-term and long-term debt at December 31, 1997 was $146 million
higher than the 1996 aggregate amount due primarily to acquisition-related debt.
The Company's working capital ratio was 2.6 to 1 at December 31, 1997 compared
with 2.8 to 1 at December 31, 1996; excluding a $53 million short-term,
acquisition-related note payable which was paid in early 1998, the Company's
working capital ratio was 2.8 to 1 at December 31, 1997.

</TABLE>
 
CASH FLOWS FROM OPERATING ACTIVITIES
 
     Continuing operations generated $64.9 million and $144.1 million more cash
in 1997 than in 1996 and 1995, respectively, primarily due to increased
earnings. During 1997, the Company's accounts receivable and inventories
increased by $92.2 million and $103.1 million, respectively, primarily as a
 
                                       13
<PAGE>   15
 
result of acquisitions and higher actual and anticipated sales volume. As
compared with the average manufacturing company, the Company maintains a higher
investment in inventories, which relates to the Company's business strategies of
providing better customer service, establishing efficient production scheduling
and benefiting from larger, more cost-effective purchasing.
 
CASH FLOWS FROM (FOR) INVESTING ACTIVITIES
 
     Investing activities of continuing operations used cash of $313.6 million
in 1997 compared with cash provided from investing activities of $564.8 million
in 1996. Cash flows from investing activities for 1996 included an aggregate
$822.6 million of cash proceeds from the sales of discontinued operations and
certain MascoTech, Inc. investments.
 
     During October 1996, the Company completed the sale to MascoTech of 17
million shares of MascoTech common stock and warrants to purchase 10 million
shares of MascoTech common stock. Under the sale agreement, the Company received
approximately $266 million, with $115 million cash paid at closing. The $151
million balance of the consideration was paid by MascoTech to the Company on
September 30, 1997; as provided for in the sale agreement, MascoTech at that
date delivered to the Company 9.9 million shares (approximately 42 percent) of
the outstanding common stock of Emco Limited and $45.6 million in cash.
MascoTech recognized a $29.3 million after-tax gain from the delivery to the
Company of the Emco Limited common stock. The Company's recording of equity
earnings from MascoTech for 1997 excludes the effect of such gain due to the
related-party nature of the transaction. Emco Limited is a leading Canadian
distributor and manufacturer of home improvement and building products.
MascoTech holds an option, expiring in 2002, to require the Company to purchase
up to $200 million aggregate amount of subordinated debt securities of
MascoTech.
 
     For the 1997 acquisitions of Texwood Industries and five other companies,
the combined purchase price was approximately $430 million, including the
assumption of debt and issuance of a short-term note aggregating $123 million,
2.9 million shares of Company common stock valued at approximately $119 million
and $187 million of cash paid.
 
     Capital expenditures totalled $167.4 million in 1997 compared with $138.5
million in 1996. These amounts primarily pertain to expenditures for additional
facilities related to increased demand for existing products as well as for new
Masco products. The Company also continues to invest in automating its
manufacturing operations and increasing its productivity, in order to be a more
efficient producer and improve customer service and response time. The Company
expects capital expenditures for 1998, excluding those of potential 1998
acquisitions, to approximate the 1997 level. Depreciation and amortization
expense for 1997 totalled $116.1 million, compared with $99.7 million for 1996;
for 1998, depreciation and amortization expense, excluding 1998 acquisitions, is
expected to be approximately $128 million.
 
     Costs of environmental responsibilities and compliance with existing
environmental laws and regulations have not had, nor in the opinion of the
Company are they expected to have, a materially adverse effect on the Company's
capital expenditures, financial position, or results of operations.
 
CASH FLOWS FOR FINANCING ACTIVITIES
 
     Cash used for financing activities decreased to $123.8 million in 1997 from
$491.7 million in 1996. During 1996, the Company paid the $250 million of 9
percent notes due April 15, 1996 through borrowings under its bank
revolving-credit agreement and applied approximately $550 million of the
proceeds from the 1996 sale of the home furnishings products segment to reduce
bank debt.
 
     During 1997, the Company increased its dividend rate 5 percent to $.21 per
share quarterly. This marks the 39th consecutive year in which dividends have
been increased.
 
     The Company believes that its present cash balance and cash flows from
operations are sufficient to fund its near-term working capital and other
investment needs. The Company believes that its longer-term working capital and
other general corporate requirements will be satisfied through cash
                                       14
<PAGE>   16
 
flows from operations and, to the extent necessary, future financial market
activities, from proceeds from assets sales and from bank borrowings.
 
CONSOLIDATED RESULTS OF OPERATIONS
 
     Sales and Operations
 
     Net sales for 1997 were $3,760 million, representing an increase of 16
percent over 1996. After adjusting for acquisitions, net sales for 1997
increased 7 percent over 1996. After adjusting for acquisitions, net sales of
the Company's North American operations for 1997 increased 8 percent over 1996.
Net sales for 1996 increased 11 percent to $3,237 million from $2,927 million in
1995; after adjusting for acquisitions and the divestiture of two small
operations, net sales increased 7 percent in 1996 over 1995.
 
     Cost of sales as a percentage of sales for 1997 remained unchanged at 63.3
percent compared with 1996 when it increased from 63.1 percent for 1995. The
modest increase in the cost of sales percentage for 1997 and 1996 as compared
with 1995 was primarily attributable to softness in the Company's European
markets, expenses associated with manufacturing process improvement initiatives
and product sales mix, which offset the benefits resulting from increased sales
volume and new product introductions.
 
     Excluding amortization of acquired goodwill ($18.7 million, $12.1 million,
and $10.0 million in 1997, 1996 and 1995, respectively), selling, general and
administrative expenses as a percentage of sales were 20.6 percent in 1997
compared with 21.5 percent and 22.8 percent for 1996 and 1995, respectively. The
downward trend in the selling, general and administrative expenses percentage
results from the Company's continuation of cost-containment initiatives, the
substitution of contingent incentive-based compensation for the reduction in
fixed compensation for certain executives and the leverage of fixed and
semi-fixed costs over a higher sales base. The Company expects selling, general
and administrative expenses as a percentage of sales to approximate 20.0 percent
by the end of 1998.
 
     Other Income (Expense), Net
 
     Equity earnings from MascoTech, Inc. in 1997 reflect the Company's mid-1997
and late-1996 reductions in common equity ownership. Equity earnings from
MascoTech were $14.6 million for 1997 as compared with equity earnings of $13.9
million and $18.2 million for 1996 and 1995, respectively. Equity earnings from
MascoTech in 1996 include the Company's $11.7 million pre-tax equity share of
MascoTech's loss from the sale of its metal stamping businesses.
 
     During the second quarter of 1997, MascoTech effected conversion of all of
its publicly held outstanding convertible preferred stock with the issuance of
approximately 10 million shares of its common stock. This conversion 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 $29.5 million during the second quarter of 1997.
 
     During 1996, the Company recognized a $67.8 million net pre-tax gain ($40.7
million after-tax) from the fourth quarter 1996 sale to MascoTech of 17 million
shares of MascoTech common stock and warrants to purchase 10 million shares of
MascoTech common stock. This gain was largely offset by $36.3 million of fourth
quarter 1996 charges primarily related to adjustments of miscellaneous assets to
their estimated fair value.
 
     Included in other, net under other income (expense), net is income from
cash and cash investments of $17.3 million, $6.9 million and $2.6 million for
1997, 1996 and 1995, respectively; the increase in 1997 resulted from a higher
average cash and cash investments balance during 1997 as compared with 1996 and
1995. The Company's cash balance for 1997 included residual proceeds from
transactions in the latter part of 1996, including the sale of certain MascoTech
investments, the sale of the Company's home furnishings businesses and European
borrowings.
                                       15
<PAGE>   17
 
     Included in other, net under other income (expense), net is interest income
for 1997 and 1996 of $36.8 million and $14.0 million, respectively, from the 12%
pay-in-kind junior debt securities of Furnishings International Inc. Such
interest income began to accrue in August 1996 upon the sale of the Company's
home furnishings businesses. Also included in other, net in 1997 and 1996 is
interest income of $7.5 million and $1.7 million, respectively, from the $151
million note receivable from MascoTech, which was paid on September 30, 1997.
 
     Included in other, net under other income (expense), net in 1997 are $10.8
million of dividend income from the Company's investment in Furnishings
International's 13% cumulative preferred stock, net gains aggregating
approximately $28 million related to the sales of certain assets and charges
aggregating approximately $30 million, principally for the adjustment of the
Company's Payless Cashways investment to its estimated fair value.
 
     Included in other, net under other income (expense), net for 1995 was a
$15.9 million gain from the sale of the Company's investment in Formica
Corporation; this gain was offset primarily by charges for asset disposals.
 
     Net Income and Earnings Per Share
 
     After-tax income from continuing operations for 1997 was $382 million
compared with $295 million for 1996 and $200 million for 1995. Basic and diluted
earnings per share from continuing operations for 1997 were $2.39 and $2.30,
respectively, as compared with basic and diluted earnings per share from
continuing operations of $1.87 and $1.82 and $1.28 and $1.25, respectively, for
1996 and 1995. The Company's effective tax rate decreased to 39.4 percent in
1997 from 41.3 percent in 1996 due to the net utilization of the Company's
capital loss carryforward benefit, recognized primarily in the fourth quarter of
1997. The 1995 tax rate of 43.1 percent was higher due primarily to an increase
in higher-taxed foreign income as a percentage of total income. The Company
estimates that its effective tax rate will approximate 40 percent for 1998.
 
OUTLOOK FOR THE COMPANY
 
     Assuming that the U.S. economy maintains its present rate of moderate
growth and interest rates remain relatively stable, the Company expects further
increases in both sales and earnings for 1998. The Company believes that its
results will be favorably affected in the future with its efforts to: continue
to invest in new manufacturing technologies and productivity improvement
initiatives in order to contain costs and increase efficiency; maintain a lower
level of selling, general and administrative expenses, as a percent of sales;
introduce new products and marketing initiatives to increase market share and
share of customer; and to actively pursue acquisition candidates that complement
or support the Company's core competencies.

BUSINESS SEGMENT RESULTS
 
     Kitchen and Bath Products
 
     Net sales of the Company's Kitchen and Bath Products increased 17 percent
in 1997 over 1996 and 10 percent in 1996 over 1995; after adjusting for
acquisitions, net sales increased 7 percent for each of the last two years, 1997
over 1996 and 1996 over 1995. These increases are largely due to higher unit
sales volume of cabinets, faucets and other kitchen and bath products, and to a
lesser extent, new product introductions and selling price increases.
 
     Operating profit of the Company's Kitchen and Bath Products, before general
corporate expense, was $539 million, $462 million and $411 million in 1997, 1996
and 1995, respectively. Operating margin, before general corporate expense,
remained unchanged at 18.3 percent for 1997 and 1996 compared with 18.0 percent
in 1995. Higher unit sales volumes in 1997 contributed to improved operating
results of the Company's U.S. cabinet, other kitchen and bath and faucet
businesses, including the leveraging of fixed and semi-fixed selling, general
and administrative expenses over a higher sales base. These improved results
were offset by the weaker results of the Company's European operations included
in this segment and the modestly lower margins of companies acquired in 1997.
 
     Operating results of this business segment showed a net improvement in 1996
over 1995 as a result of higher unit sales volume, increased efficiency and
utilization of new and existing manufacturing facilities and the leverage of
fixed and semi-fixed selling, general and administrative expenses over a higher
sales base, which more than offset the modestly weaker results of the Company's
U.S. cabinet businesses and the lower results of European operations. Operating
results of the Company's U.S. cabinet businesses were modestly weaker in 1996
and 1995 due to the influence of a higher percentage of lower margin sales to
total sales and the recognition of certain expenses for various initiatives
undertaken to improve manufacturing processes and customer service and to
shorten product delivery time.
 
     Other Specialty Products
 
     Net sales of the Company's Other Specialty Products increased 14 percent in
1997 over 1996 and 11 percent in 1996 over 1995. After adjusting for
acquisitions, net sales increased 7 percent in 1997 over 1996 and, after
adjusting for acquisitions and divestitures, increased 7 percent in 1996 over
1995. Operating profit of the Company's Other Specialty Products, before general
corporate expense, was
 
                                       17
<PAGE>   19
 
$130 million, $104 million, and $82 million in 1997, 1996 and 1995,
respectively. Operating margin, before general corporate expense, improved to
15.9 percent in 1997 from 14.5 percent in 1996 and 12.7 percent in 1995.
 
     The upward trend in operating results for this segment principally includes
the benefits of higher installation sales of fiberglass insulation and higher
unit sales volume of mechanical and electronic lock sets. Operating results of
this segment benefited in 1996 from the leverage of fixed and semi-fixed
selling, general and administrative expenses over a higher sales base and the
divestiture of two underperforming operations. Operating results were negatively
affected in 1997, 1996 and 1995 by lower results of European operations.
 
GEOGRAPHIC AREA RESULTS
 
     North America
 
     Net sales of North American operations increased 15 percent in 1997 over
1996 and 10 percent in 1996 over 1995. Net sales of North American operations,
after adjusting for acquisitions, increased 8 percent in 1997 over 1996 and,
after adjusting for acquisitions and divestitures, increased 9 percent in 1996
over 1995. Operating profit from North American operations, before general
corporate expense, was $570 million, $479 million and $407 million for 1997,
1996 and 1995, respectively. Operating margin, before general corporate expense,
improved to 18.6 percent in 1997 from 17.9 percent in 1996 and 16.7 percent in
1995.
 
     Operating results of North American operations in 1997 and 1996 benefited
from higher sales volume which was partly driven by an increase in U.S. housing
transactions, including higher levels of new construction and existing home
sales. Operating results of North American operations in 1995 were lower, in
part due to plant start-up costs related to a major new faucet facility and
product sales mix. Operating results of the Company's Canadian operations
improved in 1997 over 1996 after being relatively flat in 1996 over 1995.
 
     Europe
 
     Net sales of European operations increased 24 percent in 1997 over 1996 and
15 percent in 1996 over 1995; after adjusting for acquisitions, net sales
decreased 5 percent in 1997 as compared with 1996 and decreased 1 percent in
1996 as compared with 1995. Operating profit from European operations, before
general corporate expense, was $99 million, $87 million and $86 million for
1997, 1996 and 1995, respectively. Operating margin from European operations,
before general corporate expense, decreased to 14.4 percent in 1997 following a
decline to 15.6 percent in 1996 from 17.7 percent in 1995.
 
     Results of European operations were lower over the past three years, in
part due to softness in the Company's European markets beginning in mid-1995,
competitive pricing pressures on certain products and the influence of a higher
percentage of lower margin sales to total sales. In addition, a stronger U.S.
dollar had a negative effect on the translation of European results in 1997
compared with 1996 and 1996 compared with 1995, lowering European net sales by
approximately 12 percent and 3 percent, respectively. Excluding acquisitions,
net sales of European operations increased approximately 6 percent in local
currencies.
 
OTHER MATTERS
 
     The Company is currently working to resolve the potential impact of the
year 2000 on the processing of date-sensitive information by the Company's
computerized information and other systems. The year 2000 issue is the result of
computer programs being written using two digits (rather than four) to define
the applicable year. Any of the Company's programs that have date-sensitive
software may recognize a date using "00" as the year 1900 rather than the year
2000, which could result in miscalculations or system failures. Based on

Company's financial position, results of operations or cash flows in future
periods.
 
     On January 22, 1998, MascoTech, Inc. announced the completion of its
acquisition of TriMas Corporation. The Company will record in the first quarter
of 1998, as a result of selling its common stock investment in TriMas to
MascoTech in the public tender offer, an approximate $29 million pre-tax gain.
 
RECENTLY ISSUED STATEMENTS OF FINANCIAL ACCOUNTING STANDARDS
 
     Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting of
Comprehensive Income," SFAS No. 131, "Disclosure about Segments of an Enterprise
and Related Information," and SFAS No. 132, "Employers' Disclosure about
Pensions and Other Postretirement Benefits," become effective in 1998 and should
not have a material effect on the Company's financial statements.
 
QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK
 
     The Company considered the provisions of Financial Reporting Release No. 48
"Disclosure of Accounting Policies for Derivative Financial Instruments and
Derivative Commodity Instruments, and Disclosure of Quantitative and Qualitative
Information about Market Risk Inherent in Derivative Financial Instruments,
Other Financial Instruments and Derivative Commodity Instruments." The Company
had no holdings of derivative financial or commodity-based instruments at
December 31, 1997. A review of the Company's other financial instruments and
risk exposures at that date revealed that the Company had exposure to interest
rate and foreign currency exchange rate risks. At December 31, 1997, the Company
performed sensitivity analyses to assess the potential effect of these risks and
concluded that near-term changes in interest rates and foreign currency exchange
rates should not materially affect the Company's financial position, results of
operations or cash flows.
 
     Other discussion regarding the Company's business risks is presented in the
"Overview" caption above and in Item 1 "Business" of this Form 10-K.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA.
 
                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors
and Shareholders of Masco Corporation:
 
     We have audited the accompanying consolidated balance sheets of Masco
Corporation and subsidiaries as of December 31, 1997 and 1996, and the related
consolidated statements of operations and cash flows for each of the three years
in the period ended December 31, 1997 and the financial statement schedule as
listed in Item 14(a)(2) of the Form 10-K. These financial statements and
financial statement schedule are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements and
financial statement schedule based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Masco
Corporation and subsidiaries as of December 31, 1997 and 1996, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1997 in conformity with generally
accepted accounting principles. In addition, in our opinion, the financial
statement schedule referred to above, when considered in relation to the basic
financial statements taken as a whole, presents fairly, in all material
respects, the information required to be included therein.

                               MASCO CORPORATION
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
ACCOUNTING POLICIES
 
     Principles of Consolidation. The consolidated financial statements include
the accounts of Masco Corporation and all majority-owned subsidiaries. All
significant intercompany transactions have been eliminated. The Company
classified its home furnishings products segment as discontinued operations in
1995. (See "Discontinued Operations" note.) Accordingly, the financial
statements and related notes present the home furnishings products segment as
discontinued operations. Certain amounts for prior years have been reclassified
to conform to the current year presentation.
 
     Use of Estimates in the Preparation of Financial Statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires the Company to make certain estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from such estimates and
assumptions.
 
     Cash and Cash Investments. The Company considers all highly liquid
investments with a maturity of three months or less to be cash and cash
investments.
 
     Receivables. The Company does significant business with a number of
individual customers, including home centers. The Company monitors its exposure
for credit losses and maintains adequate allowances for doubtful accounts; the
Company does not believe that significant credit risks exist. At December 31,
1997 and 1996 accounts and notes receivable are presented net of allowances for
doubtful accounts of $19.8 million and $17.9 million, respectively.
 
     Property and Equipment. Property and equipment, including significant
betterments to existing facilities, are recorded at cost. Upon retirement or
disposal, the cost and accumulated depreciation are removed from the accounts
and any gain or loss is included in the statement of operations. Maintenance and
repair costs are charged to expense as incurred.
 
     Depreciation and Amortization. Depreciation is computed principally using
the straight-line method over the estimated useful lives of the assets. Annual
depreciation rates are as follows: buildings and land improvements, 2 to 10
percent, and machinery and equipment, 5 to 33 percent. Depreciation was $81.4
million, $71.7 million and $65.3 million in 1997, 1996 and 1995, respectively.
 
     Acquired goodwill, resulting from acquisitions of companies, is being
amortized using the straight-line method over periods not exceeding 40 years; at
December 31, 1997 and 1996 such accumulated amortization totalled $82.8 million
and $70.2 million, respectively. At each balance sheet date, management
evaluates the recoverability of acquired goodwill by measuring the carrying
value of the asset to the associated current and projected annual sales,
operating profit and undiscounted annual cash flows; management also considers
business prospects, market trends and other economic factors in performing this
evaluation. Based on this evaluation, there was no permanent impairment related
to acquired goodwill at December 31, 1997 and 1996. Purchase costs of patents
are being amortized using the straight-line method over the legal lives of the
patents, not to exceed 17 years. Amortization of intangible assets totalled
$34.6 million, $28.0 million and $24.8 million in 1997, 1996 and 1995,
respectively.
 
     Fair Value of Financial Instruments. The carrying value of financial
instruments reported in the balance sheet for current assets and current
liabilities approximates fair value. The fair value of financial instruments
that are carried as long-term investments (other than those accounted for by the
equity method) was based principally on quoted market prices for those or
similar investments or by discounting future cash flows using a discount rate
that approximates the risk of the underlying investments. The fair value of the
Company's long-term debt instruments was based principally on
 
                                       24

ACCOUNTING POLICIES -- (CONCLUDED)
quoted market prices for the same or similar issues or the current rates
available to the Company for debt with similar terms and remaining maturities.
The aggregate market value of the Company's long-term investments and long-term
debt at December 31, 1997 was approximately $509 million and $1,386 million, as
compared with the Company's aggregate carrying value of $498 million and $1,321
million, respectively, and at December 31, 1996 the aggregate market value was
approximately $631 million and $1,248 million, as compared with the Company's
aggregate carrying value of $601 million and $1,236 million, respectively.
 
ACQUISITIONS
 
     During 1997, the Company acquired Texwood Industries, Inc., a U.S.
manufacturer of kitchen and bath cabinetry, and five other home improvement and
building products companies, including two companies in Europe.
 
     The results of operations for these acquisitions are included in the
consolidated financial statements from the dates of acquisition. Had these
companies been acquired effective January 1, 1996, pro forma unaudited
consolidated net sales and net income would have approximated $3,909 million and
$390 million for 1997 and $3,575 million and $309 million for 1996,
respectively, and pro forma unaudited consolidated diluted earnings per share
would have approximated $2.33 and $1.87 for 1997 and 1996, respectively.
 
     The combined purchase price for these acquisitions, including assumed debt,
aggregated approximately $430 million and included approximately 2.9 million
shares of Company common stock, with the balance in cash and a short-term note.
The acquisitions were accounted for as purchase transactions. The net cash paid
for companies acquired in 1997 is as follows, in thousands:

DISCONTINUED OPERATIONS
 
     In late November 1995, the Company's Board of Directors approved a formal
plan to dispose of the Company's home furnishings products segment. An aggregate
provision of $650 million was recorded in the fourth quarter of 1995 for the
estimated loss on the discontinued operations through the expected disposal
date, the reduction of assets to their estimated net realizable value and the
anticipated liabilities related to the disposal.
 
     Basic and diluted earnings per share for 1995 from discontinued operations
were both $.05. Basic and diluted loss per share for 1995 from the loss on
disposition of discontinued operations were $4.15 and $4.05, respectively.

DISCONTINUED OPERATIONS -- (CONCLUDED)
     During August 1996, the Company completed the sale of its home furnishings
products segment to Furnishings International Inc. Total proceeds to the Company
from the sale were, in millions:

Total proceeds from the sale................................         $1,050

</TABLE>
 
     The junior debt securities mature in 2008. The convertible preferred stock
represents transferable rights for up to a 25 percent common ownership, although
the Company is restricted from maintaining an ownership in excess of 20 percent
of Furnishings International's common equity. As such, the Company will not
acquire additional common equity, except for purposes of resale only. Of the
cash proceeds received from this sale, approximately $550 million was applied to
reduce bank debt.
 
     Under a transitional services agreement, the Company provided
corporate-related services for a fee to Furnishings International through April
1997. Substantially all of these services were discontinued after such date.

     Excluding the partnership interest in Hans Grohe, for which there is no
quoted market value, the aggregate market value of the Company's equity
investments at December 31, 1997 (which may differ from the amounts that could
then have been realized upon disposition), based upon quoted market prices at
that date, was $319 million, as compared with the Company's related aggregate
carrying value

of $182 million. The Company's carrying value in common stock of these equity
affiliates exceeds its equity in the underlying net book value by approximately
$79 million at December 31, 1997. This excess is being amortized over a period
not to exceed 40 years.
 
     During the second quarter of 1997, MascoTech effected conversion of all of
its publicly held outstanding convertible preferred stock with the issuance of
approximately 10 million shares of its common stock. This conversion 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.
 
     MascoTech holds an option expiring in 2002 to require the Company to
purchase up to $200 million aggregate amount of subordinated debt securities of
MascoTech.
 
     During the fourth quarter of 1996, the Company completed the sale to
MascoTech of 17 million shares of MascoTech common stock and warrants to
purchase 10 million shares of MascoTech common stock. This transaction reduced
the Company's common equity ownership in MascoTech from 45 percent to 21 percent
and resulted in a fourth quarter 1996 pre-tax gain of $67.8 million ($40.7
million after-tax). Under the sale agreement, the Company received approximately
$266 million, with $115 million paid at closing. The Company earned interest
income at 6.625% on the $151 million balance of the consideration, which was
paid by MascoTech to the Company on September 30, 1997; as provided for in the
sale agreement, MascoTech at that date delivered to the Company 9.9 million
shares (approximately 42 percent) of the outstanding common stock of Emco
Limited and $45.6 million in cash. MascoTech recognized a $29.3 million
after-tax gain from the delivery to the Company of the Emco Limited common
stock. The Company's recording of equity earnings from MascoTech for 1997
excludes the effect of such gain due to the related-party nature of the
transaction. Emco Limited is a leading Canadian distributor and manufacturer of
home improvement and building products.
 
     On January 22, 1998, MascoTech announced the completion of its acquisition
of TriMas Corporation. The Company will record in the first quarter of 1998, as
a result of selling its common stock investment in TriMas to MascoTech in the
public tender offer, an approximate $29 million pre-tax gain.

     European bank debt relates to borrowings of local currency for acquisitions
and expansion, primarily in Germany. At December 31, 1997, approximately $222
million of European debt related to a term loan facility expiring in 2002. The
balance of $107 million represents borrowings under lines of credit primarily
expiring in 2002. Interest is payable on European borrowings based upon various
floating rates as selected by the Company (approximately 4 percent at December
31, 1997).
 
     The Company called the 5.25% subordinated debentures due 2012 for
redemption on February 12, 1998. Substantially all holders exercised their right
to convert these debentures into Company common stock (at the conversion price
of $42.28 per share), resulting in the issuance of approximately 4.2 million
shares of Company common stock in February 1998.
 
     Certain debt agreements contain limitations on additional borrowings and
requirements for maintaining a certain level of tangible net worth. At December
31, 1997, the Company was in compliance with these limitations and requirements,
and the Company's tangible net worth exceeded the most restrictive of such
provisions by approximately $171 million.

     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 $759 million of debt and equity securities.

     In December 1995, the Company's Board of Directors announced the approval
of a Shareholder Rights Plan. The Rights were designed to enhance the Board's
ability to protect the Company's shareholders against, among other things,
unsolicited attempts to acquire control of the Company that do not offer an
adequate price to all shareholders or are otherwise not in the best interests of
the shareholders. The Rights were issued to shareholders of record in December
1995 and will expire in December 2005.

     Financial statements of non-U.S. operations are translated into U.S.

of operations. Adjustments resulting from such translation are reflected as
cumulative translation adjustments in shareholders' equity.
 
     At December 31, 1997, the Company had remaining authorization to repurchase
up to 7.2 million shares of its common stock in open-market transactions or
otherwise.
 
STOCK OPTIONS AND AWARDS
 
     The Company's 1991 Long Term Stock Incentive Plan (the "Plan") provides for
the issuance of stock-based incentives in various forms. At December 31, 1997,
outstanding stock-based incentives were primarily in the form of restricted
long-term stock awards and stock options.
 
     The Company granted long-term stock awards, net of cancellations, for
790,000, 540,000 and 1,250,000 shares of Company common stock during 1997, 1996
and 1995, respectively, to key employees of the Company and to non-employee
Directors of the Company. These long-term stock awards do not cause net share
dilution inasmuch as the Company reacquires an equal number of shares on the
open market. The weighted average grant date fair value per share of long-term
stock awards granted during 1997, 1996 and 1995 was $42, $31 and $27,
respectively. Compensation expense for the annual vesting of long-term stock
awards was $14.0 million, $14.9 million and $13.3 million in 1997, 1996 and
1995, respectively. The unamortized costs of unvested stock awards, aggregating
approximately $95.5 million at December 31, 1997, are included in other assets
and are being amortized over the typical 10-year vesting periods.
 
     Fixed stock options are granted to key employees of the Company and to
non-employee Directors of the Company, and have a maximum term of 10 years. The
exercise price of each fixed option, other than the option described below to
the Company's Chief Executive Officer granted during 1996 at an exercise price
in excess of the current market price, equals the market price of Company common
stock on the date of grant. These options generally vest in installments
beginning in the third year and extending through the eighth year after grant.
 
     During 1997, the Company granted original stock options for 2,840,000
shares of Company common stock with an exercise price of $39 per share (equal to
the market price on the grant date). Twenty percent of such options became
exercisable in late 1997 when the Company's common stock price exceeded $50 per
share for the required period. An additional twenty percent will become
exercisable if the price of Company common stock exceeds $55 for the required
period by May 2000; the remaining sixty percent (eighty percent if the $55
target was not exceeded) of such options will become exercisable if the price of
Company common stock reaches $60 per share for the required period by May 2001.
If neither target is met, the remaining eighty percent of such options become
exercisable in March 2007; however, the recipients of these options have stated
that they will not exercise them unless they become exercisable earlier as a
result of meeting the price targets. The Company also granted restoration stock
options for 139,000 shares of Company common stock with grant date exercise
prices ranging from $35 to $52 (the market prices on the grant dates) and stock
options for 28,000 shares of Company common stock to non-employee Directors of
the Company with an exercise price of $39.
 
     To demonstrate his commitment to increase the market value of Company
common stock for the benefit of shareholders, in 1996 the Company's Chief
Executive Officer requested that his annual salary and bonus be reduced
indefinitely to $1 per year effective January 1, 1996. The Compensation
Committee of the Board of Directors, in acceding to this request, considered
alternative compensation

STOCK OPTIONS AND AWARDS -- (CONTINUED)
arrangements for the Chief Executive Officer and in April 1996 granted the Chief
Executive Officer a 10-year option, with a $41 exercise price when the market
price was $27 7/8 per share, to purchase one million shares of Company common
stock. This option became exercisable in 1997 when the price of Company common
stock exceeded $41 per share.
 
     As a demonstration of their commitment to enhance shareholder value and
alignment with shareholder interests, in 1996 other officers and certain other
key employees of the Company voluntarily accepted an effective 15 percent salary
reduction with salaries frozen indefinitely at that level. This reduction in
compensation was replaced with stock options and career stock awards. The stock
options were granted with an exercise price of $32 (equal to the market price on
the grant date). Annual vestings of such stock options commenced in 1997 as a
result of the Company common stock price exceeding $41 per share for the
required period. Such options were granted for approximately 1,615,000 shares of
Company common stock. In addition, in 1996 when the market price of Company
common stock was $32 per share, the executive officers were granted career stock
awards; annual vestings of such awards commenced in 1997 as a result of the
Company common stock price exceeding $50 per share for the required period in
late 1997.
 
     A summary of the status of the Company's stock options granted for the
three years ended December 31, 1997 is presented below.

common stock was available for the granting of stock options and long-term stock
awards under the Plan.
 
     During 1997, the Company adopted the "1997 Non-Employee Directors Stock
Plan" (the "Directors Stock Plan"), which provides for the payment of
compensation to non-employee Directors in part in Company common stock.
Approximately 51,000 shares of Company common stock were granted in 1997 in the
form of stock options and long-term stock awards under this plan. Such options
and long-term stock awards are included in the information provided above. At

option compensation expense been determined pursuant to the methodology of
Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for
Stock-Based Compensation," the pro forma effect would have been a reduction in
the Company's diluted earnings per share of approximately $.05 and $.03 in 1997
and 1996, respectively, with no effect in 1995.
 
     For SFAS 123 calculation purposes, the weighted average grant date fair
values of options granted in 1997, 1996 and 1995 were $12.54, $11.20 and $8.44,
respectively. The fair values of these options were estimated at the grant dates
using a Black-Scholes option pricing model with the following assumptions for
1997, 1996 and 1995, respectively: risk free interest rate -- 6.7%, 6.7% and
6.5%; dividend yield -- 2.5% (all years); volatility factor -- 27%, 25% and 27%;
and expected option life -- 7 years (all years).
 
     Pursuant to the 1984 Restricted Stock (MascoTech) Incentive Plan, the
Company may award to key employees of the Company and affiliated companies
shares of common stock of MascoTech, Inc. held by the Company. No such awards
were granted in 1997, 1996 or 1995. At December 31, 1997, there were 4,695,000
of such shares available for granting future awards under this plan.
 
     The data in this note include discontinued operations.

which provide for pension benefits in addition to those provided by the
qualified pension plans. The actuarial present value of accumulated benefit
obligations and projected benefit obligations related to these non-qualified
pension plans totalled $30.8 million and $39.1 million, and $24.7 million and
$30.2 million at December 31, 1997 and 1996, respectively; net periodic pension
cost for these plans was $4.7 million, $4.9 million and $3.7 million in 1997,

     The Company sponsors certain postretirement benefit plans that provide
medical, dental and life insurance coverage for eligible retirees and dependents
in the United States based on age and length of service. At December 31, 1997,
the aggregate present value of the unfunded accumulated postretirement benefit
obligation approximated $4.0 million.

     During the second quarter of 1997, MascoTech effected conversion of all of
its publicly held outstanding convertible preferred stock with the issuance of
approximately 10 million shares of its common stock. This conversion 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 $29.5 million during the second quarter of 1997.
 
     Other interest income for 1997 and 1996 includes $36.8 million and $14.0
million, respectively, from the 12% pay-in-kind junior debt securities of
Furnishings International Inc. Such interest income began to accrue in August
1996 upon the sale of the Company's home furnishings businesses. Other interest
income for 1997 and 1996 also includes $7.5 million and $1.7 million,
respectively of interest income from the $151 million note receivable from
MascoTech which was paid on September 30, 1997.
 
     Other items in 1997 include $10.8 million of dividend income from the
Company's investment in Furnishings International's 13% cumulative preferred
stock and net gains aggregating approximately $28 million related to the sales
of certain assets, as well as charges aggregating approximately $30 million
principally for the adjustment of the Company's Payless Cashways investment to
its estimated fair value. Other items in 1996 include $36.3 million of fourth
quarter charges primarily related to adjustments of miscellaneous assets to
their estimated fair value.
 
     Interest expense in 1996 and 1995 is presented net of interest expense
pertaining to discontinued operations of $21.8 million and $44.0 million,
respectively.

     Net deferred tax liability at December 31, 1997 and 1996 consists of net
short-term deferred tax assets of $19.0 million and $14.5 million, respectively,
and net long-term deferred tax liabilities of $82.5 million and $43.1 million,
respectively.
 
     A valuation allowance of approximately $175.0 million and $206.3 million
was recorded at December 31, 1997 and 1996, respectively, primarily due to the
Company's inability to quantify the major portion of its capital loss
carryforward which may ultimately be realized. Such capital loss benefit
resulted from a $149.5 million and $164.0 million after-tax capital loss
carryforward on the disposition of the Company's home furnishings products
segment at December 31, 1997 and 1996, respectively, and a $25.5 million and
$42.3 million after-tax future deductible temporary difference of a capital
nature on the Company's equity and other investments at December 31, 1997 and
1996, respectively.

     Income taxes paid were approximately $178 million, $201 million and $170
million in 1997, 1996 and 1995, respectively. Amounts paid in 1996 and 1995
include taxes on discontinued operations.
 
     Earnings of non-U.S. subsidiaries generally become subject to U.S. tax upon
the remittance of dividends and under certain other circumstances. Provision has
not been made at December 31, 1997 for U.S. or additional foreign withholding
taxes on approximately $6.0 million of remaining undistributed net income of
non-U.S. subsidiaries, as such income is intended to be permanently reinvested;
it is not practical to estimate the amount of deferred tax liability on such
income.
 
EARNINGS PER SHARE
 
     At December 31, 1997, the Company adopted Statement of Financial Accounting
Standards ("SFAS") No. 128, "Earnings Per Share," which replaces the
presentation of primary and fully diluted earnings per share, as computed under
Accounting Principles Board ("APB") Opinion No. 15, with a presentation of basic
and diluted earnings per share. The financial statements have been retroactively
restated to conform with the earnings per share presentation required under SFAS
No. 128.
 
     The following are reconciliations of the numerators and denominators used
in the computations of basic and diluted earnings per share, in thousands:

     Fourth quarter net income in 1997 benefited (approximately $.02 per diluted
share) from a reduction in the effective tax rate to 38.0% from 40.0% due
primarily to the net utilization of the Company's capital loss carryforward
benefit.
 
     The fourth quarter of 1996 includes a $67.8 million net pre-tax gain from
the sale of certain MascoTech, Inc. investments ($40.7 million after-tax or $.25
per diluted share). This gain was principally offset by fourth quarter charges
aggregating $49.1 million pre-tax ($37.5 million after-tax or $.23 per diluted
share) primarily for adjustments of miscellaneous assets to their estimated fair
value.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors
  and Shareholders of MascoTech, Inc.:
 
     We have audited the accompanying consolidated balance sheet of MascoTech,
Inc. and subsidiaries as of December 31, 1997 and 1996, and the related
consolidated statements of income and cash flows for each of the three years in
the period ended December 31, 1997 and the financial statement schedule as
listed in Item 14(a)(2)(ii)(A) and (B) of this Form 10-K. These financial
statements and the financial statement schedule are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements and financial statement schedule based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of MascoTech, Inc.
and subsidiaries as of December 31, 1997 and 1996, and the consolidated results
of their operations and their cash flows for each of the three years in the
period ended December 31, 1997, in conformity with generally accepted accounting
principles. In addition, in our opinion, the financial statement schedule
referred to above, when considered in relation to the basic financial statements
taken as a whole, presents fairly, in all material respects, the information
required to be included therein.
 
     As discussed in the footnotes to the consolidated financial statements,
effective January 1, 1996, the Company changed its method of accounting for the
impairment of long-lived assets and for long-lived assets to be disposed of.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
ACCOUNTING POLICIES:
 
     Principles of Consolidation. The consolidated financial statements include
the accounts of the Company and all majority-owned subsidiaries. All significant
intercompany transactions have been eliminated. Corporations that are 20 to 50
percent owned are accounted for by the equity method of accounting; ownership
less than 20 percent is accounted for on the cost basis unless the Company
exercises significant influence over the investee. Capital transactions by
equity affiliates, which change the Company's ownership interest at amounts
differing from the Company's carrying amount, are reflected in other income or
expense and the investment in affiliates account.
 
     The consolidated balance sheet at December 31, 1996 reflects the
segregation of net current and net non-current assets related to the disposition
of the Company's Technical Services Group ("TSG").
 
     The Company has a corporate services agreement with Masco Corporation,
which at December 31, 1997 owned approximately 17 percent of the Company's
Common Stock. Under the terms of the agreement, the Company pays fees to Masco
Corporation for various corporate staff support and administrative services,
research and development and facilities. Such fees, which are determined
principally as a percentage of net sales, aggregated approximately $5.5 million
in 1997, $7.1 million in 1996, and $9.1 million in 1995.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the Company to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements. Such estimates and assumptions also affect the reported amounts of
revenues and expenses during the reporting periods. Actual results may differ
from such estimates and assumptions.
 
     Cash and Cash Investments. The Company considers all highly liquid debt
instruments with an initial maturity of three months or less to be cash and cash
investments. The carrying amount reported in the balance sheet for cash and cash
investments approximates fair value.
 
     Marketable Securities. The Company's marketable equity securities holdings
are categorized as trading and, as a result, are stated at fair value. Changes
in the fair value of trading securities are recognized in earnings. Derivative
financial instruments, consisting principally of S&P futures contracts, are held
for purposes other than trading and are carried at market value. Changes in
market value of outstanding futures contracts are recognized in earnings.
 
     Receivables. Receivables are presented net of allowances for doubtful
accounts of approximately $1.2 million and $2.0 million at December 31, 1997 and
1996, respectively.
 
     Inventories. Inventories are stated at the lower of cost or net realizable
value, with cost determined principally by use of the first-in, first-out
method.
 
     Property and Equipment, Net. Property and equipment additions, including
significant betterments, are recorded at cost. Upon retirement or disposal of
property and equipment, the cost and accumulated depreciation are removed from
the accounts, and any gain or loss is included in income. Repair and maintenance
costs are charged to expense as incurred.
 
     Depreciation and Amortization. Depreciation is computed principally using
the straight-line method over the estimated useful lives of the assets. Annual
depreciation rates are as follows: buildings and land improvements, 2 1/2 to 10
percent, and machinery and equipment, 6 2/3 to 33 1/3 percent. Deferred
financing costs are amortized over the lives of the related debt securities. The
excess of cost over net assets of acquired companies is amortized using the
straight-line method over the period estimated to be benefitted, not exceeding
40 years. At each balance sheet date, management assesses whether there has been
a permanent impairment of the excess of cost over net assets of acquired
companies by

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
comparing anticipated undiscounted future cash flows from operating activities
with the carrying amount of the excess of cost over net assets of acquired
companies. The factors considered by management in performing this assessment
include current operating results, business prospects, market trends, potential
product obsolescence, competitive activities and other economic factors. Based
on this assessment, there was no permanent impairment related to the excess of
cost over net assets of acquired companies at December 31, 1997.
 
     At December 31, 1997 and 1996, accumulated amortization of the excess of
cost over net assets of acquired companies and patents was $33.2 million and
$29.4 million, respectively. Amortization expense was $9.3 million, $8.5 million
and $13.7 million in 1997, 1996 and 1995, respectively.
 
     Income Taxes. The Company records income taxes in accordance with Statement
of Financial Accounting Standards ("SFAS") No. 109 ("SFAS No. 109"), "Accounting
for Income Taxes." SFAS No. 109 is an asset and liability approach that requires
the recognition of deferred tax assets and liabilities for the expected future
tax consequences of events that have been recognized in the Company's financial
statements or tax returns. In estimating future tax consequences, SFAS No. 109
generally allows consideration of all expected future events other than
enactments of changes in the tax law or tax rates. A provision has not been made
for U.S. or additional foreign withholding taxes on approximately $49 million of
undistributed earnings of foreign subsidiaries as those earnings are intended to
be permanently reinvested. Generally, such earnings become subject to U.S. tax
upon the remittance of dividends and under certain other circumstances. It is
not practicable to estimate the amount of deferred tax liability on such
undistributed earnings.
 
     New Accounting Pronouncements and Reclassifications. At December 31, 1997,
the Company adopted SFAS No. 128, "Earnings Per Share," which replaces the
presentation of primary and fully diluted earnings per share, as computed under
Accounting Principles Board Opinion No. 15, with a presentation of basic and
diluted earnings per share. The financial statements have been retroactively
restated to conform with the earnings per share presentation required under SFAS
No. 128.
 
     In addition, the Company has reclassified the unamortized cost of unvested
restricted stock awards from other assets to a separate component of
shareholders' equity (see "Stock Options and Awards" note). Prior periods have
been reclassified to conform to this and other presentations adopted in calendar
year 1997.
 
     At January 1, 1996, the Company adopted SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of,"
which resulted in a pre-tax gain (because the fair value of the businesses being
held for sale at January 1, 1996 exceeded the carrying value for such
businesses) of $16.7 million ($11.7 million after-tax), recorded as the
cumulative effect of an accounting change. The pro forma effect of the
retroactive application of the change on the financial statements for 1995 has
not been presented because the new method did not have a material effect on the
reported earnings.
 
     In 1998, the Company will adopt the disclosure requirements of SFAS No.
130, "Reporting of Comprehensive Income," SFAS No. 131, "Disclosure about
Segments of an Enterprise and Related Information," and SFAS No. 132,
"Employers' Disclosure about Pensions and Other Postretirement Benefits." The
adoption of these disclosures will not impact earnings per common share in 1998.

     Diluted earnings per share reflect the potential dilution that would occur
if securities or other contracts to issue common stock were exercised or
converted into common stock. The Company's preferred stock and convertible
debentures did not have a dilutive effect on earnings per share in 1996 and
1995.
 
SUPPLEMENTARY CASH FLOWS INFORMATION:
 
     Significant transactions not affecting cash were: in 1997: the conversion
of the Company's outstanding shares of Dividend Enhanced Convertible Preferred
Stock on June 27, 1997 for approximately 10 million shares of Company Common
Stock (see "Shareholders' Equity" note); the exchange of approximately 9.9
million shares of the outstanding common stock of Emco Limited ("Emco") with a
value of approximately $106 million, in addition to the cash payment of
approximately $46 million, in payment of a promissory note due to Masco
Corporation; in 1996: in addition to cash received, approximately $25 million
comprised of both common stock and warrants (with a portion of the common stock
subsequently sold for approximately $14 million of cash), as consideration from
the sale of MascoTech Stamping Technologies, Inc.; in addition to the cash
payment by the Company of $121 million, notes approximating $159 million were
issued for the purchase of 18 million shares of the Company's Common Stock and
warrants to purchase 10 million shares of the Company's Common Stock (see
"Shareholders' Equity" note); in 1995: in addition to cash received,

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
$34 million comprised of both notes receivable due from, and a 29 percent equity
interest in, the acquiring company, as consideration for a non-core business
unit.
 
     Income taxes paid (refunded) were $44 million, $(12) million and $11
million in 1997, 1996 and 1995, respectively. Interest paid was $39 million, $30
million and $55 million in 1997, 1996 and 1995, respectively.
 
DISPOSITIONS OF OPERATIONS:
 
     In late 1994, the Company adopted a plan to dispose, by sale or
liquidation, a number of businesses, including its architectural products,
defense and certain of its transportation-related products and services
businesses, as part of its long-term strategic plan to increase the focus on its
core operating capabilities. The Company has completed the disposition of such
businesses.
 
     During 1995, the Company divested a number of such businesses, in separate
transactions, for aggregate proceeds of approximately $180 million, which
resulted in net gains of approximately $25 million. These net gains were
substantially offset by reductions in the estimated net proceeds the Company
expected to receive from certain remaining businesses to be sold, aggregating
approximately $12 million, and by certain exit costs incurred in 1995
aggregating approximately $8 million.
 
     In May 1996, the Company sold MascoTech Stamping Technologies, Inc.
("MSTI"), a wholly owned subsidiary, to Tower Automotive, Inc. ("Tower")
resulting in an after-tax loss of approximately $26 million ($.49 per common
share), including after-tax losses of approximately $1 million related to the
closure of a MSTI manufacturing facility not included in the sale. The Company
received initial consideration of approximately $80 million, consisting
principally of $55 million in cash, 785,000 shares of Tower common stock and
warrants to purchase additional Tower common stock (200,000 shares at $18 per
share expiring May 31, 1999). The Company applied the cash proceeds (including
approximately $14 million received from the subsequent sale of 600,000 shares of
Tower common stock) to reduce its indebtedness. The Company may receive
additional consideration (up to $30 million), of which approximately $5 million
was earned in 1997, contingent upon the future earnings of MSTI through May 31,
1999.
 
     On January 3, 1997, the Company sold its Technical Services Group
(comprised of the Company's engineering and technical business services units)
to MSX International, Inc. Also included in this transaction were the net assets
of APX International which were acquired by the Company in November 1996 for
approximately $44 million. The sale resulted in total proceeds to the Company of
approximately $145 million, subject to certain adjustments, consisting of cash,
$30 million of subordinated debentures, $18 million of preferred stock and an
approximate 45 percent common equity interest in MSX International, Inc. valued
at $2 million. In January 1998, the Company received $48 million of cash from
MSX International, Inc. in payment of the subordinated debentures and other
amounts due MascoTech resulting in a realized gain in the first quarter 1998
(gain recognition was deferred at the time of the transaction pending cash
receipt) of approximately $7 million. The remaining deferred gain of
approximately $20 million will be recognized upon the liquidation of the common
and preferred stock holdings for cash. The net assets of the Technical Services
Group and APX International are reflected on the consolidated balance sheet as
net assets of businesses held for disposition at December 31, 1996. The Company
did not reflect any revenues or expenses in the consolidated statement of income
related to APX International from the date of acquisition through January 3,
1997 as control was deemed to be temporary.
 
     The disposition of businesses did not meet the criteria for discontinued
operations treatment for accounting purposes; accordingly, the sales and results
of operations of these businesses were included in continuing operations until
disposition. Businesses held for sale or sold, including MSTI and TSG,

     In June 1995, Titan sold newly issued common stock in a public offering and
issued common stock as a result of the conversion of convertible securities. The
Company recognized pre-tax income of approximately $5.1 million as a result of
the change in the Company's common equity ownership interest in Titan. In
December 1996, Titan called for redemption its 4 3/4% Convertible Subordinated
Notes which resulted in the issuance of approximately 4.5 million common shares,
reducing the Company's common equity ownership interest in Titan to
approximately 12 percent. As a result, the investment in Titan at December 31,
1996 was accounted for as available-for-sale. In March 1997, Titan repurchased
approximately 5.6 million shares of its common stock, increasing the Company's
common equity ownership interest in Titan to approximately 15 percent. As a
result, the investment in Titan has been accounted for under the equity method
of accounting.
 
     In March 1997, TriMas called for redemption its 5% Convertible Subordinated
Debentures which resulted in the issuance of approximately 4.7 million common
shares, reducing the Company's common equity ownership in TriMas to
approximately 37 percent. The Company recognized pre-tax income of approximately
$13 million as a result of the change in the Company's common equity ownership
interest in TriMas.
 
     In September 1997, the Company exercised its option and exchanged its
equity holdings in Emco, with a value approximating $106 million, and
approximately $46 million in cash to satisfy the indebtedness to Masco
Corporation incurred in 1996 in connection with the Company's purchase and
retirement of certain of its securities held by Masco Corporation. This
transaction resulted in a pre-tax gain of approximately $46 million. In
addition, the Company has an investment in Emco subordinated notes which are
classified as available-for-sale and, as a result, are recorded at fair value.
As a result of the sale of Emco equity, the Emco subordinated notes were
reclassified to other assets in 1997. The Company has recorded unrealized gains
of approximately $1 million and $2 million in 1997 and 1996, respectively, which
have been recorded as an adjustment to shareholders' equity.
 
     In December 1997, DRI completed an initial public offering reducing the
Company's common equity ownership interest in DRI to approximately 12 percent on
a diluted basis (the Company owns approximately 18 percent of the voting common
stock). As a result of the change in the Company's

common equity ownership interest in DRI, the Company recognized pre-tax income
of approximately $5 million.
 
     In addition to its equity and other investments in publicly traded
affiliates, the Company has equity and other investment interests in privately
held automotive related companies, including the Company's common equity
ownership in Saturn Electronics & Engineering, Inc., a manufacturer of
electromechanical and electronic automotive components, and MSX International,
Inc., a transportation-focused engineering and technical services company.
 
     Equity in undistributed earnings of affiliates of $68 million at December
31, 1997, $57 million at December 31, 1996 and $38 million at December 31, 1995
are included in consolidated retained earnings.

     The interest rates applicable to the Company's revolving credit agreement
at December 31, 1997 are principally at alternative floating rates provided for
in the agreement (approximately six percent at December 31, 1997).
 
     In connection with the TriMas acquisition in early 1998 (see "Subsequent
Event" note), the Company entered into a new $1.3 billion credit facility. This
facility includes a $500 million term loan with principal payments as follows:
1998 - $25 million; 1999 - $40 million; 2000 - $60 million; 2001 - $75 million;
and 2002 - $190 million. The remainder of the term loan and the $800 million
revolver terminate in 2003. The Company has the ability and intent to refinance
amounts due in 1998 on a long-term basis.
 
     The interest rates applicable to the new credit facility are principally at
alternative floating rates which would have approximated 6.5 percent at December
31, 1997. The new credit facility requires the maintenance of a specified level
of shareholders' equity plus subordinated debt, with limitations on the ratios
of total debt to cash flow (as defined) and cash flow less capital expenditures
(as defined) to interest plus scheduled debt payments. In addition, there are
limitations on dividends, share repurchases and subordinated debt repurchases.
Under the most restrictive of these provisions, approximately $40 million would
have been available at December 31, 1997 for the payment of cash dividends and
the acquisition of Company capital stock. The facility is collateralized by a
pledge of the stock of TriMas.
 
     The note held by Masco Corporation was part of the consideration paid by
the Company in 1996 for the purchase of 17 million shares of MascoTech common
stock and warrants to purchase 10 million shares of MascoTech common stock from
Masco Corporation. In September 1997, the Company exercised its option and
exchanged its equity holdings in Emco Limited, with a value approximating $106
million, and approximately $46 million in cash to Masco Corporation to satisfy
this indebtedness.
 
     The maturities of debt as at December 31, 1997 during the next five years
are as follows (not taking into account the new credit facility) (in millions):
1998 - $3; 1999 - $4; 2000 - $2; 2001 - $.7; and 2002 - $.5.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     On June 27, 1997, the Company completed the conversion of all remaining
issued and outstanding shares of its Dividend Enhanced Convertible Preferred
Stock (DECS). Holders of DECS received in exchange for each share of DECS .955
of a share of the Company's Common Stock, par value $1.00 per share, resulting
in the issuance of approximately 10 million shares of Company Common Stock.
 
     On October 31, 1996, the Company purchased from Masco Corporation 17
million shares of MascoTech common stock and warrants to purchase 10 million
shares of MascoTech common stock, for cash and notes approximating $266 million.
As part of this 1996 transaction, Richard A. Manoogian, Chairman of both Masco
Corporation and MascoTech, also sold to MascoTech one million shares of
MascoTech common stock (at the then current market price) for approximately
$13.6 million. In addition, as part of this transaction, Masco Corporation's
agreement to purchase from the Company, at the Company's option, up to $200
million of subordinated debentures was extended through 2002, and the corporate
services agreement with Masco Corporation was extended until September 30, 1998.
Masco Corporation also agreed that MascoTech will have the right of first
refusal to purchase the approximate 7.8 million shares of MascoTech common stock
that Masco Corporation continues to hold, should Masco Corporation decide to
dispose of such shares.
 
     In addition, the Company repurchased and retired approximately .3 million
shares of its common stock and approximately .5 million shares of its preferred
stock in 1997, and approximately one million shares of its common stock in each
of 1996 and 1995 in open-market purchases, pursuant to a Board of Directors'
authorized repurchase program. At December 31, 1997, the Company may repurchase
approximately three million additional shares of Company Common Stock pursuant
to this repurchase authorization.
 
     On the basis of amounts paid (declared), cash dividends per common share
were $.22 ($.28) in 1997, $.18 ($.18) in 1996 and $.14 ($.11) in 1995.
 
STOCK OPTIONS AND AWARDS:
 
     The Company's Long Term Stock Incentive Plan (the "Plan") provides for the
issuance of stock-based incentives in various forms. At December 31, 1997,
outstanding stock-based incentives are in the form of restricted long-term stock
awards and stock options.
 
     Pursuant to the Plan, the Company granted long-term stock awards, net, for
565,000, 480,000 and 461,000 shares of Company Common Stock during 1997, 1996
and 1995, respectively, to key employees of the Company and affiliated
companies. The weighted average fair value per share of long-term stock awards
granted during 1997, 1996 and 1995 on the date of grant was $19, $14 and $12,
respectively. Compensation expense for the vesting of long-term stock awards was
approximately $4.7 million, $2.3 million and $4.8 million in 1997, 1996 and
1995, respectively. The unamortized costs of unvested stock awards, aggregating
approximately $33 million at December 31, 1997, are being amortized over the
ten-year vesting periods and are a deduction from shareholders' equity.
 
     Fixed stock options are granted to key employees of the Company and
affiliated companies and have a maximum term of 10 years. The exercise price of
each fixed option equals the market price of Company Common Stock on the date of
grant. These options either vest no later than 10 years after grant or in
installments beginning in the third year and extending through the eighth year
after grant.

     At December 31, 1997, options have been granted and are outstanding with
exercise prices ranging from $4 1/2 to $25 per share, the fair market values at
the dates of grant.
 
     At December 31, 1997 and 1996, a combined total of 5,223,000 and 4,656,000
shares, respectively, of Company Common Stock were available for the granting of
options and incentive awards under the above plans.
 
     The Company has elected to continue to apply the provisions of Accounting
Principles Board Opinion No. 25 and, accordingly, no stock option compensation
expense is included in the determination of net income in the statement of
income. The weighted average fair value on the date of grant of options granted
was $7.70 and $6.20 in 1997 and 1996, respectively. Had stock option
compensation expense been determined pursuant to the methodology of Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation," the pro forma effects on the Company's earnings per share would
have approximated $.02 and $.01 in 1997 and 1996, respectively, and had no
effect in 1995.
 
     The fair value for these options was estimated at the date of grant using a
Black-Scholes option pricing model with the following weighted average
assumptions:

EMPLOYEE BENEFIT PLANS:
 
     Pension and Profit-Sharing Benefits. The Company sponsors defined-benefit
pension plans for most of its employees. In addition, substantially all salaried
employees participate in noncontributory profit-sharing plans, to which payments
are approved annually by the Directors. Aggregate charges to income under these
plans were $9 million in 1997, $11 million in 1996 and $13 million in 1995.

     The discount rate used in determining the accumulated postretirement
benefit obligation was 7.25 percent in both 1997 and 1996. The change in the
accumulated postretirement benefit obligation and the unrecognized net gain
amounts is the result of the change in the actuarial assumptions concerning the
health care cost trend rate. The assumed health care cost trend rate in 1997 was
nine percent, decreasing to an ultimate rate in the year 2007 of five percent.
If the assumed medical cost trend rates were increased by one percent, the
accumulated postretirement benefit obligation would increase by $.7 million and
the aggregate of the service and interest cost components of net periodic
postretirement benefit cost would increase by $.1 million.

(A) Included within this segment are sales to one customer of $140 million, $232
    million and $397 million in 1997, 1996 and 1995, respectively; sales to
    another customer of $79 million, $146 million and $182 million in 1997, 1996
    and 1995, respectively; sales to a third customer of $62 million, $122
    million and $178 million in 1997, 1996 and 1995, respectively; and sales to
    a fourth customer of $156 million, $155 million and $136 million in 1997,
    1996 and 1995, respectively.
 
(B) Operating profit in 1996 includes a $32 million pre-tax loss principally
    from the sale of MascoTech Stamping Technologies, Inc. ("MSTI"). Operating
    profit in 1997 includes approximately $5 million of additional pre-tax
    consideration earned from the sale of MSTI which was sold in 1996. These
    items impacted the Company's Transportation-Related Products and Services
    industry segment. The Company may receive additional consideration
    contingent upon the future earnings of MSTI through May 31, 1999. Operating
    profit in 1995 includes $25 million in net gains resulting from sales of
    non-core businesses. These net gains were substantially offset by reductions
    in the estimated proceeds the Company expected to receive from businesses to
    be sold, aggregating $12 million, and by certain exit costs incurred in 1995
    aggregating approximately $8 million. The net gains (charge) impact the
    Company's industry segments as follows: Transportation-Related Products and
    Services - $21 million and Specialty Products - $(2) million. The remaining
    $(14) million of the net gains (charge) was allocated to General Corporate
    Expense.
 
(C) Assets employed at December 31, 1996 and 1995 include net assets related to
    the disposition of certain operations (see "Dispositions of Operations"
    note).
 
(D) Property additions include approximately $2 million and $14 million in 1996
    and 1995, respectively, of capital expenditures for those businesses held
    for disposition related to the plan adopted in late 1994.
 
(E) Depreciation and amortization expense includes approximately $5 million in
    1995 of expense for those businesses held for disposition related to the
    plan adopted in late 1994.
 
(F) The Company's foreign operations are located principally in Western Europe.

FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     In accordance with Statement of Financial Accounting Standards No. 107,
"Disclosures about Fair Value of Financial Instruments," the following methods
were used to estimate the fair value of each class of financial instruments:
 
MARKETABLE SECURITIES, NOTES RECEIVABLE AND OTHER ASSETS
 
     Fair values of financial instruments included in marketable securities,
notes receivable and other assets were estimated using various methods including
quoted market prices and discounted future cash flows based on the incremental
borrowing rates for similar types of investments. In addition, for variable-rate
notes receivable that fluctuate with the prime rate, the carrying amounts
approximate fair value.
 
LONG-TERM DEBT
 
     The carrying amount of bank debt and certain other long-term debt
instruments approximate fair value as the floating rates inherent in this debt
reflect changes in overall market interest rates. The fair values of the
Company's subordinated debt instruments are based on quoted market prices. The
fair values of certain other debt instruments are estimated by discounting
future cash flows based on the Company's incremental borrowing rate for similar
types of debt instruments.
 
DERIVATIVES
 
     The Company has limited involvement with derivative financial instruments,
and does not use derivatives for trading purposes. The derivatives, principally
consisting of S&P futures contracts, are intended to reduce the market risk
associated with the Company's marketable equity securities portfolio. The
Company's investment in futures contracts increases in value as a result of
decreases in the underlying index and decreases in value when the underlying
index increases. The contracts are financial instruments (with off-balance sheet
market risk), as they are required to be settled in cash. The Company's market
risk is subject to the price differential between the contract market value and
contract cost. The average monthly notional amount of derivative contracts in
1997 was approximately $17 million and there were no contracts outstanding at
December 31, 1997.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     Futures contracts trade on organized exchanges, and as a result, settlement
of such contracts has little credit risk. Initial margin requirements are met in
cash or other instruments, and changes in the contract values are settled
periodically. Initial margin requirements are recorded as cash investments in
the balance sheet. Futures contracts are short-term in nature, usually less than
six months.
 
     The carrying amounts and fair values of the Company's financial instruments
at December 31, 1997 and 1996 are as follows:

     Results for the first and fourth quarters 1997 include pre-tax gains of
approximately $13 million and $5 million, respectively, as a result of equity
transactions by affiliates of the Company.
 
     Results for the first, second, third and fourth quarters 1997 include
pre-tax marketable securities gains (losses) of approximately $5.0 million, $4.0
million, $4.4 million and $(.3) million, respectively.
 
     Results for the third quarter 1997 include a pre-tax gain of approximately
$46 million related to the transfer of the Company's equity holdings in Emco
Limited to Masco Corporation. This gain was partially offset by pre-tax costs
approximating $14 million associated with a plant closure and the Company's
share of a special charge recorded by an equity affiliate and other expenses.
 
     Results for the fourth quarter 1997 include approximately $5 million
pre-tax of additional consideration earned from the sale of MascoTech Stamping
Technologies, Inc. which was sold in the second quarter 1996.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONCLUDED)
 
     Results for the fourth quarter 1997 were negatively impacted by charges
aggregating approximately $10 million pre-tax principally related to severance,
the Company's share of a charge recorded by an equity affiliate, write-off of
deferred charges and loss on disposition of fixed assets.
 
     Convertible securities were anti-dilutive in the first quarter 1996 for
purposes of computing diluted earnings per common share and earnings per common
share on income before accounting change.
 
     Results for the second quarter 1996 include an after-tax loss of
approximately $26 million related to the sale of MascoTech Stamping
Technologies, Inc.
 
     Net income for the first quarter of 1996 includes an after-tax gain of
approximately $12 million as a result of the adoption of Statement of Financial
Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of," effective January 1, 1996
which was recorded as a cumulative effect of an accounting change.
 
     The 1997 and 1996 income (loss) per common share amounts for the quarters
do not total to the full year amounts due to the purchase and retirement of
shares throughout the year.
 
SUBSEQUENT EVENT:
 
     In January 1998, the Company completed its tender offer for all of the
outstanding shares of common stock of TriMas Corporation not held by the Company
for approximately $920 million in accordance with the terms of the Company's
previously announced acquisition agreement with TriMas.
 
     The acquisition will be accounted for as a purchase in 1998. The purchase
price will be allocated to the previously unowned assets acquired and
liabilities assumed based upon their estimated fair values. The excess of the
purchase price over the net assets acquired will be amortized over a period not
exceeding 40 years. The purchase price allocation will be determined during 1998
when appraisals, other studies and additional information become available.
Results of operations for TriMas will be included with those of the Company for
periods subsequent to the date of the acquisition.
 
     TriMas is a diversified proprietary products company with leadership
positions in commercial, industrial and consumer niche markets.
 
     The following is summarized financial data of TriMas as of and for the year
ended December 31, 1997:

                    RESTATED CERTIFICATE OF INCORPORATION

                                     OF

                              MASCO CORPORATION

                                  * * * * *

        MASCO CORPORATION, a corporation organized and existing  under the laws
of the State of Delaware, hereby certifies as  follows: 

        1.  The name of the corporation is MASCO CORPORATION.  The date of
filing its original Certificate of Incorporation  with the Secretary of State
was June 15, 1962.

        2.  This Restated Certificate of Incorporation only restates and
integrates and does not further amend the provisions of the Certificate of
Incorporation of this corporation as heretofore amended or supplemented and
there is no discrepancy between those provisions and the provisions of this
Restated Certificate of Incorporation.

        3.   The text of the Certificate of Incorporation as amended or
supplemented heretofore is hereby restated without  further amendments or
changes to read as herein set forth in  full: 

        FIRST:   The name of the corporation is MASCO CORPORATION.

        SECOND:  Its registered office in the State of Delaware is 

<PAGE>   2

located at the Corporation Trust Center, 1209  Orange Street, in the City of    
Wilmington, County of New Castle.  The name and address of its registered agent
is The Corporation Trust Company, 1209 Orange Street, Wilmington, Delaware
19801.

        THIRD:  The nature of the business, or objects or purposes to be
transacted, promoted or carried on are:  To engage in any lawful act or
activity for which corporations may be organized under the General Corporation
Law of Delaware.

        FOURTH:  The total number of shares of stock the Corporation shall have
authority to issue is four hundred one million (401,000,000) shares.

        Four hundred million (400,000,000) of such shares shall consist of
common shares, par value one dollar ($1.00) per share, and one million
(1,000,000) of such shares shall consist of preferred shares, par value one
dollar ($1.00) per share.

        The designations and the powers, preferences and rights, and the
qualifications, limitations or restrictions thereof are as follows:

            A.  Each share of common stock shall be equal in all respects to all
      other shares of such stock, and each share of outstanding common stock is
      entitled to one vote.

            B.  Each share of preferred stock shall have or not have voting 
      rights as determined by the Board of Directors prior to issuance.

            Dividends on all outstanding shares of preferred stock must be
      declared and paid, or set aside for payment, before any dividends can be
      declared and paid, or set aside for payment, on the shares of common stock
      with respect to the same dividend period.

            In the event of any liquidation, dissolution or winding up of the
      affairs of the Corporation, whether voluntary or involuntary, the holders
      of the preferred stock shall be entitled, before any assets of the 
      Corporation shall be distributed among or paid over to the holders of the
      common stock, to an amount per share to be determined before issuance 



                                        -2-

<PAGE>   3


      by the Board of Directors, together with a sum of money equivalent to the
      amount of any dividends declared thereon and remaining unpaid at the date
      of such liquidation, dissolution or winding up of the Corporation.  After
      the making of such payments to the holders of the preferred stock, the
      remaining assets of the Corporation shall be distributed among the
      holders of the common stock alone, according to the number of shares held
      by each.  If, upon such liquidation, dissolution or winding up, the
      assets of the Corporation distributable as aforesaid among the holders of
      the preferred stock shall be insufficient to permit the payment to them
      of said amount, the entire assets shall be distributed ratably among the
      holders of the preferred stock.
        
            The Board of Directors shall have authority to divide the shares of
      preferred stock into series and fix, from time to time, before issuance,
      the number of shares to be included in any series and the designation,
      relative rights, preferences and limitations of all shares of such
      series.  The authority of the Board of Directors with respect to each
      series shall include the determination of any or all of the following,
      and the shares of each series may vary from the shares of any other in
      the following respects: (a) the number of shares constituting such series
      and the designation thereof to distinguish the shares of such series from
      the shares of all other series; (b) the rate of dividend, cumulative or
      noncumulative, and the extent of further participation in dividend
      distribution, if any; (c) the prices at which issued (at not less than
      par) and the terms and conditions upon which the shares may be redeemable
      by the Corporation; (d) sinking fund provisions for the redemption or
      purchase of shares; (e) the voting rights; and (f) the terms and
      conditions upon which the shares are convertible into other classes of
      stock of the Corporation, if such shares are to be convertible.
        
                C.  No holder of any class of stock issued by this Corporation
      shall be entitled to preemptive rights.

        FIFTH:  The Corporation is to have perpetual existence.

        SIXTH:  The private property of the stockholders shall not be subject
to the payment of corporate debts to any extent whatever.


                                        -3-

        SEVENTH: (a) The business and affairs of the Corporation shall be
managed by or under the direction of a Board of Directors consisting of not
less than five nor more than twelve directors, the exact number of directors to
be determined from time to time by resolution adopted by affirmative vote of a
majority of the entire Board of Directors.  The directors shall be divided into
three classes, designated Class I, Class II and Class III.  Each class shall
consist, as nearly as may be possible, of one-third of the total number of
directors constituting the entire Board of Directors.  At the 1988 Annual
Meeting of stockholders, Class I directors shall be elected for a one-year
term, Class II directors for a two-year term and Class III directors for a
three-year term.  At each succeeding Annual Meeting of stockholders beginning
in 1989, successors to the class of directors whose term expires at that annual
meeting shall be elected for a three-year term.  If the number of directors is
changed, any increase or decrease shall be apportioned among the classes so as
to maintain the number of directors in each class as nearly equal as possible,
and any additional director of any class elected to fill a vacancy resulting
from an increase in such class shall hold office for a term that shall coincide
with the remaining term of that class, but in no case will a decrease in the
number of directors shorten the term of any incumbent director.  A director
shall hold office until the annual meeting for the year in which his term
expires and until his successor shall be elected and shall qualify, subject,
however, to prior death, resignation, retirement or removal from office. 
Except as otherwise required by law, any vacancy on the Board of Directors that
results from an increase in the number of directors shall be filled only by a
majority of the Board of Directors then in office, provided that a quorum is
present, and any other vacancy occurring in the Board of Directors shall be
filled only by a majority of the directors then in office, even if less than a
quorum, or by a sole remaining director.  Any director elected to fill a
vacancy not resulting from an increase in the number of directors shall serve
for the remaining term of his predecessor.

        Notwithstanding the foregoing, whenever the holders of any one or more
classes or series of preferred stock or any other class of stock issued by the
Corporation shall have the right, voting separately by class or series, to
elect directors at an annual or special meeting of stockholders, the election,
term of office, filling of vacancies and other features of such directorships
shall be governed by the terms of the Certificate of Designation with 

                                        -4-

<PAGE>   5


respect to such stock, such directors so elected shall not be divided into
classes pursuant to this Article SEVENTH, and the number of such directors
shall not be counted in determining the maximum number of directors permitted 
under the foregoing provisions of this Article SEVENTH, in each case unless 
expressly provided by such terms.

        (b) Nominations for the election of directors may be made by the Board
of Directors or by any stockholder entitled to vote in the election of
directors.  Any stockholder entitled to vote in the election of directors,
however, may nominate one or more persons for election as director only if
written notice of such stock-  holder's intent to make such nomination or
nominations has been given either by personal delivery or by United States
mail, postage prepaid, to the Secretary of the Corporation not later than (i)
with respect to an election to be held at an Annual Meeting of stockholders, 45
days in advance of the date on which the Corporation's proxy statement was
released to stockholders in connection with the previous year's Annual Meeting
of stockholders and (ii) with respect to an election to be held at a special
meeting of stockholders for the election of directors, the close of business on
the seventh day following the day on which notice of such meeting is first
given to stockholders.  Each such notice shall include:   (A) the name and
address of the stockholder who intends to make the nomination or nominations
and of the person or persons to be nominated; (B) a representation that the
stockholder is a holder of record of stock of the Corporation entitled to vote
at such meeting and intends to appear in person or by proxy at the meeting to
nominate the person or persons specified in the notice; (C) a description of
all arrangements or understandings between such stockholder and each nominee
and any other person or persons (naming such person or persons) pursuant to
which the nomination or nominations is or are to be made by the stockholder;
(D) such other information regarding each nominee proposed by such stockholder
as would have been required to be included in a proxy statement filed pursuant
to the proxy rules of the Securities and Exchange Commission if the nominee had
been nominated by the Board of Directors; and (E) the written consent of each
nominee to serve as a director of the Corporation if elected.  The chairman of
any meeting of stockholders may refuse to acknowledge the nomination of any
person if not made in compliance with the foregoing procedure.


                                        -5-

        (c)  Notwithstanding any other provision of this Certificate of
Incorporation or the by-laws (and notwithstanding the fact that a lesser
percentage may be specified by law, this Certificate of Incorporation or the
by-laws), and in addition to any affirmative vote required by law, the
affirmative vote of the holders of at least 80% of the voting power of the
outstanding capital stock of the Corporation entitled to vote, voting together
as a single class, shall be required to amend, adopt in this Certificate of
Incorporation or in the by-laws any provision inconsistent with, or repeal this
Article SEVENTH.

        EIGHTH:  Any action required or permitted to be taken by the
stockholders of the Corporation must be effected at a duly called annual or
special meeting of such holders and may not be effected by any consent in
writing by any such holders.  Except as otherwise required by law, special
meetings of stockholders of the Corporation may be called only by the
Chairman of the Board, the President or a majority of the Board of Directors,
subject to the rights of holders of any one or more classes or series of
preferred stock or any other class of stock issued by the Corporation which
shall have the right, voting separately by class or series, to elect directors. 
Notwithstanding any other provision of this Certificate of Incorporation or the
by-laws (and notwithstanding that a lesser percentage may be specified by law,
this Certificate of Incorporation or the by-laws), and in addition to any
affirmative vote required by law, the affirmative vote of the holders of at
least 80% of the voting power of the outstanding capital stock of the
Corporation entitled to vote, voting together as a single class, shall be
required to amend, adopt in this Certificate of Incorporation or in the by-laws
any provision inconsistent with, or repeal this Article EIGHTH.

        NINTH:  In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors is expressly authorized:

        To make, alter or repeal the by-laws of the Corporation.

        To authorize and cause to be executed mortgages and liens upon the real
and personal property of the Corporation.

        To set apart out of any of the funds of the Corporation available for
dividends a reserve or reserves for any proper 



                                        -6-


<PAGE>   7
purpose and to abolish any such reserve in the manner in which it was created.

        By resolution passed by a majority of the whole board, to designate one
or more committees, each committee to consist of two or more of the Directors
of the Corporation, which, to the extent provided in the resolution or in the
by-laws of the Corporation, shall have and may exercise the powers of the Board
of Directors in the management of the business and affairs of the Corporation,
and may authorize the seal of the Corporation to be affixed to all papers which
may require it. Such committee or committees shall have such name or names as
may be stated in the by-laws of the Corporation or as may be determined from
time to time by resolution adopted by the Board of Directors.

        When and as authorized by the affirmative vote of the holders of a
majority of the stock issued and outstanding having voting power given at a
stockholders' meeting duly called for that purpose, to sell, lease or exchange
all of the property and assets of the Corporation, including its good will and
its corporate franchises, upon such terms and conditions and for such
consideration, which may be in whole or in part shares of stock in, and/or
other securities of, any other corporation or corporations, as its Board of
Directors shall deem expedient and for the best interests of the Corporation.

        TENTH:  Whenever a compromise or arrangement is proposed between this
Corporation and its creditors or any class of them and/or between this
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this Corporation or of any creditor or stockholder thereof, or on the
application of any receiver or receivers appointed for this Corporation under
the provisions of Section 279 of Title 8 of the Delaware Code order a meeting
of the creditors or class of creditors, and/or of the stockholders or class of
stockholders of this Corporation, as the case may be, to be summoned in such
manner as the said court directs.  If a majority in number representing
three-fourths in value of the creditors or class of creditors, and/or of the
stockholders or class of stockholders of this Corporation, as the case may be,
agree to any compromise or arrangement and to any reorganization of this
Corporation as consequence of such compromise or arrangement, the said
compromise
 
                                        -7-

<PAGE>   8

or arrangement and the said reorganization shall, if sanctioned by the court to 
which the said application has been made, be binding on all the creditors or
class of creditors, and/or on all the stockholders or class of stockholders, of
this Corporation, as the case may be, and also on this Corporation.

        ELEVENTH:  Meetings of stockholders may be held outside the State of
Delaware, if the by-laws so provide.  The books of the Corporation may be kept
(subject to any provision contained in the statutes) outside the State of
Delaware at such place or places as may be designated from time to time by the
Board of Directors or in the by-laws of the Corporation. Elections of Directors
need not be by ballot unless the by-laws of the Corporation shall so provide.

        TWELFTH:  The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this certificate of incorporation, in the
manner now or hereafter prescribed by statute, and all rights conferred upon
stockholders herein are granted subject to this reservation.

        THIRTEENTH: 1.  The affirmative vote of the holders of 95% of all
shares of stock of the Corporation entitled to vote in elections of directors,
considered for the purposes of this Article THIRTEENTH as one class, shall be
required for the adoption or authorization of a business combination (as
hereinafter defined) with any other entity (as hereinafter defined) if, as of
the record date for the determination of stockholders entitled to notice
thereof and to vote thereon, such other entity is the beneficial owner,
directly or indirectly, of 30% or more of the outstanding shares of stock of
the Corporation entitled to vote in elections of directors considered for the
purposes of this Article THIRTEENTH as one class; provided that such 95% voting
requirement shall not be applicable if:

        (a) The cash, or fair market value of other consideration, to be
received per share by common stockholders of the Corporation in such business
combination bears the same or a greater percentage relationship to the market
price of the Corporation's common stock immediately prior to the announcement
of such business combination as the highest per share price (including
brokerage commissions and soliciting dealers' fees) which such other entity has
theretofore paid for any of the shares of the Corporation's common stock
already owned by it bears to the market price of the common stock 


                                        -8-

<PAGE>   9


of the Corporation immediately prior to the commencement of acquisition of the
Corporation's common stock by such other entity;

        (b) The cash, or fair market value of other consideration, to be
received per share by common stockholders of the Corporation in such business
combination (i) is not less than the highest per share price (including
brokerage commissions and soliciting dealers' fees) paid by such other entity
in acquiring any of its holdings of the Corporation's common stock, and (ii) is
not less than the earnings per share of common stock of the Corporation for the
four full consecutive fiscal quarters immediately preceding the record date for
solicitation of votes on such business combination, multiplied by the then
price/earnings multiple (if any) of such other entity as customarily computed
and reported in the financial community;

        (c) After such other entity has acquired a 30% interest and prior to
the consummation of such business combination: (i) such other entity shall have
taken steps to ensure that the Corpora-  tion's Board of Directors included at
all times representation by continuing director(s) (as hereinafter defined)
proportionate to the stockholdings of the Corporation's public common
stockholders not affiliated with such other entity (with a continuing director
to occupy any resulting fractional board position); (ii) there shall have been
no reduction in the rate of dividends payable on the Corporation's common stock
except as necessary to insure that a quarterly dividend payment does not exceed
5% of the net income of the Corporation for the four full consecutive fiscal
quarters immediately preceding the declaration date of such dividend, or except
as may have been approved by a unanimous vote of the directors; (iii) such
other entity shall not have acquired any newly issued shares of stock, directly
or indirectly, from the Corporation (except upon conversion of convertible
securities acquired by it prior to obtaining a 30% interest or as a result of a
pro rata stock dividend or stock split); and (iv) such other entity shall not
have acquired any additional shares of the Corporation's outstanding common
stock or securities convertible into common stock except as a part of the
transaction which results in such other entity acquiring its 30% interest;

        (d) Such other entity shall not have (i) received the benefit, directly
or indirectly (except proportionately as a stockholder) of any loans, advances,
guarantees, pledges or other financial assis-  



                                        -9-

<PAGE>   10


tance or tax credits of or provided by the Corporation, or (ii) made any major
change in the Corporation's business or equity capital structure without the
unanimous approval of the directors, in either case prior to the consummation of
such business combination; and

prominent place, any recommendations as to the advisability (or inadvisability)
of the business combination which the continuing directors, or any of them, may
choose to state and, if deemed advisable by a majority of the continuing
directors, an opinion of a reputable investment banking firm as to the fairness
(or not) of the terms of such business combination, from the point of view of
the remaining public stockholders of the Corporation (such investment banking
firm to be selected by a majority of the continuing directors and to be paid a
reasonable fee for their services by the Corporation upon receipt of such
opinion).

        The provisions of this Article THIRTEENTH shall also apply to a
business combination with any other entity which at any time has been the
beneficial owner, directly or indirectly, of 30% or more of the outstanding
shares of stock of the Corporation entitled to vote in elections of directors
considered for the purposes of this Article THIRTEENTH as one class,
notwithstanding the fact that such other entity has reduced its shareholdings
below 30% if, as of the record date for the determination of stockholders
entitled to notice of and to vote on to the business combination, such other
entity is an "affiliate" of the Corporation (as hereinafter defined).

        2.  As used in this Article THIRTEENTH, (a) the term "other entity"
shall include any corporation, person or other entity and any other entity with

any agreement, arrangement or understanding or upon exercise of conversion
rights, warrants or options, or otherwise; (c) the outstanding shares of any
class of stock of the Corporation shall include shares deemed owned through
application of clause (b) above but shall not include any other shares which
may be issuable pursuant to any agreement, or upon exercise of conversion
rights, warrants or options, or otherwise; (d) the term "business combination"
shall include any merger or consolidation of the Corporation with or into any
other entity, or the sale or lease of all or any substantial part of the assets
of the Corporation to, or any sale or lease to the Corporation or any

business combination with such other entity in which the Corporation is the
surviving corporation.

        3.  A majority of the continuing directors shall have the power and
duty to determine for the purposes of this Article THIRTEENTH on the basis of
information known to them whether (a) such other entity beneficially owns 30%
or more of the outstanding shares of stock of the Corporation entitled to vote
in elections of directors; (b) an other entity is an "affiliate" or "associate"
(as defined above) of another; (c) an other entity has an agreement,

        4.  No amendment to the Certificate of Incorporation of the Corporation
shall amend or repeal any of the provisions of this Article THIRTEENTH, unless
the amendment effecting such amendment or repeal shall receive the affirmative
vote of the holders of 95% of all shares of stock of the corporation entitled
to vote in elections of directors, considered for the purposes of this Article
THIRTEENTH as one class; provided that this paragraph 4 shall not apply to, and
such 95% vote shall not be required for, any amendment or repeal unanimously
recommended to the stockholders by the Board of Directors of the Corporation if
all of such directors are persons who would be eligible to serve as "continuing
directors" within the meaning of paragraph 2 of this Article THIRTEENTH.

        5.  Nothing contained in this Article THIRTEENTH shall be construed to
relieve any other entity from any fiduciary obligation imposed by law.

        FOURTEENTH:  A director of this Corporation shall not be personally
liable to the Corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director, except for liability (a) for any breach of the
director's duty of loyalty to the Corporation or its stockholders, (b) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (c) under Section 174 of the Delaware General
Corporation Law, or (d) for any transaction from which the director derived an
improper personal benefit.  If the Delaware General Corporation Law hereafter
is amended to authorize the further limitation or elimination of the liability
of directors, then the liability of a director of the Corporation, in addition
to the limitation on liability provided herein, shall be limited to the fullest
extent permitted by the Delaware General Corporation Law, as amended.  Any
repeal or modification of this Article FOURTEENTH shall not increase the
liability of any director of this Corporation for any act or occurrence taking
place prior to such repeal or modification, or otherwise adversely affect any
right or protection of a director of the Corporation existing at the time of
such repeal or modification.

        FIFTEENTH: 1.  Each person who was or is made a party or is threatened
to be made a party to or is otherwise involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative, by reason
of the fact that such person is or was 



                                       -12-

<PAGE>   13
a director, officer or employee of the Corporation, whether the basis of such
proceeding is alleged action in an official capacity as a director, officer or
employee or in any other capacity while serving as a director, officer, or      
employee, shall be indemnified and held harmless by the Corporation to the
fullest extent permitted by the Delaware General Corporation Law, as the same
exists or may hereafter be amended (but, in the case of any such amendment,
only to the extent that such amendment permits the Corporation to provide
broader indemnification rights than such law permitted the Corporation to
provide prior to such amendment), against all expense, liability and loss
(including, without limitation, attorneys' fees, judgments, fines and amounts
paid in settlement) reasonably incurred or suffered by such person in
connection therewith, and such indemnification shall continue as to a person
who has ceased to be a director, officer or employee and shall inure to the
benefit of such person's heirs, executors and administrators.  The Corporation
shall indemnify a director, officer or employee in connection with an action,
suit or proceeding (other than an action, suit or proceeding to enforce
indemnification rights provided for herein or elsewhere) initiated by such
director, officer or employee only if such action, suit or proceeding was
authorized by the Board of Directors.  The right to indemnification conferred
in this Paragraph 1 shall be a contract right and shall include the right to be
paid by the Corporation the expenses incurred in defending any action, suit or
proceeding in advance of its final disposition; provided, however, that, if the
Delaware General Corporation Law requires, the payment of such expenses
incurred by a director or officer in such person's capacity as a director or
officer (and not in any other capacity in which service was or is rendered by
such person) in advance of the final disposition of an action, suit or
proceeding shall be made only upon delivery to the Corporation of an
undertaking, by or on behalf of such director or officer, to repay all amounts
so advanced if it shall ultimately be determined by final judicial decision
from which there is no further right to appeal that such director or officer is
not entitled to be indemnified for such expenses under this Article FIFTEENTH
or otherwise.

        2.  The Corporation may, to the extent authorized from time to time by
the Board of Directors, provide indemnification and the advancement of
expenses, to any agent of the Corporation and to any person (other than
directors, officers and employees of the Corporation, who shall be entitled
to indemnification under Paragraph 1 



                                       -13-

<PAGE>   14


above) who is or was serving at the request of the Corporation as a director,
officer, employee or agent of another corporation or of a partnership, joint    
venture, trust or other enterprise, to such extent and to such effect as the
Board of Directors shall determine to be appropriate and permitted by
applicable law, as the same exists or may hereafter be amended.

        3.  The rights to indemnification and to the advancement of expenses
conferred in this Article FIFTEENTH shall not be exclusive of any other right
which any person may have or hereafter acquire under any statute, provision of
the Certificate of Incorporation or by-laws of the Corporation, agreement, vote
of stockholders or disinterested directors or otherwise.

        4.  This Restated Certificate of Incorporation was duly adopted by the
Board of Directors in accordance with Section 245 of the General Corporation
Law of Delaware.

               IN WITNESS WHEREOF, said MASCO CORPORATION has caused its 
corporate seal to be affixed and this Certificate to be signed by Richard A. 
Manoogian, its Chairman of the Board, and attested by Gerald Bright, its 
Secretary, this 25th day of May, 1988.

                                 MASCO CORPORATION

                          Pursuant to Section 151 of the
                          General Corporation Law of the
                                 State of Delaware




        We, Richard G. Mosteller, Senior Vice President - Finance, and Eugene
A. Gargaro, Jr., Vice President and Secretary, of Masco Corporation, a
corporation organized and existing under the General Corporation Law of the
State of Delaware ("Delaware Law"), in accordance with the provisions thereof,
DO HEREBY CERTIFY:

        That pursuant to the authority conferred upon the Board of Directors by
the Certificate of Incorporation of the Corporation, the Board of Directors on
December 6, 1995, adopted the following resolution creating a series of
Preferred Stock in the amount and having the designation, voting powers,
preferences and relative, participating, optional and other special rights and
qualifications, limitations and restrictions thereof as follows:

        Section 1.  Designation and Number of Shares.  The shares of such
series shall be designated as "Series A Participating Cumulative Preferred
Stock" (the "Series A Preferred Stock"), and the number of shares constituting
such series shall be 175,106.  


<PAGE>   20


Such number of shares of the Series A Preferred Stock may be increased or
decreased by resolution of the Board of Directors; provided that no decrease
shall reduce the number of shares of Series A Preferred Stock to a number
less than the number of shares then outstanding plus the number of shares
issuable upon exercise or conversion of outstanding rights, options or other
securities issued by the Corporation.


<PAGE>   21



        Section 2.  Dividends and Distributions.

        (A)  The holders of shares of Series A Preferred Stock shall be
entitled to receive, when, as and if declared by the Board of Directors out of
funds legally available for the purpose, quarterly dividends payable on
February 15, May 15, August 15 and November 15 of each year (each such date
being referred to herein as a "Quarterly Dividend Payment Date"), commencing on
the first Quarterly Dividend Payment Date after the first issuance of any share
or fraction of a share of Series A Preferred Stock, in an amount per share
(rounded to the nearest cent) equal to the greater of (a) $1.00 and (b) subject
to the provision for adjustment hereinafter set forth, 1,000 times the
aggregate per share amount of all cash dividends or other distributions and
1,000 times the aggregate per share amount of all non-cash dividends or other
distributions (other than (i) a dividend payable in shares of Common Stock, par
value $1.00 per share, of the Corporation (the "Common Stock") or (ii) a
subdivision of the outstanding shares of Common Stock (by reclassification or
otherwise)), declared on the Common Stock since the immediately preceding
Quarterly Dividend Payment Date, or, with respect to the first Quarterly
Dividend Payment Date, since the first issuance of any share or fraction of a
share of Series A Preferred Stock.  If the Corporation shall at any time after
December 6, 1995 (the "Rights Declaration Date") pay any dividend on Common
Stock payable in shares of Common Stock or effect a subdivision or combination
of the outstanding shares of Common Stock (by reclassification or otherwise)
into a greater or lesser number of shares of Common Stock, then in each such
case the amount to which holders of shares of Series A Preferred Stock were
entitled immediately prior to such event under clause (b) of the preceding
sentence shall be adjusted by multiplying such amount by a fraction the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

        (B)  The Corporation shall declare a dividend or distribution on the
Series A Preferred Stock as provided in paragraph (A) above immediately after
it declares a dividend or distribution on the Common Stock (other than as
described in clauses (i) and (ii) of the first sentence of paragraph (A)); 


<PAGE>   22


provided that if no dividend or distribution shall have been declared on the
Common Stock during the period between any Quarterly Dividend Payment Date and
the next subsequent Quarterly Dividend Payment Date (or, with respect to the
first Quarterly Dividend Payment Date, the period between the first issuance of
any share or fraction of a share of Series A Preferred Stock and such first
Quarterly Dividend Payment Date), a dividend of $1.00 per share on the Series A
Preferred Stock shall nevertheless be payable on such subsequent Quarterly
Dividend Payment Date.

        (C)  Dividends shall begin to accrue and be cumulative on outstanding
shares of Series A Preferred Stock from the Quarterly Dividend Payment Date
next preceding the date of issue of such shares of Series A Preferred Stock,
unless the date of issue of such shares is on or before the record date for the
first Quarterly Dividend Payment Date, in which case dividends on such shares
shall begin to accrue and be cumulative from the date of issue of such shares,
or unless the date of issue is a date after the record date for the
determination of holders of shares of Series A Preferred Stock entitled to
receive a quarterly dividend and on or before such Quarterly Dividend Payment
Date, in which case dividends shall begin to accrue and be cumulative from such
Quarterly Dividend Payment Date.  Accrued but unpaid dividends shall not bear
interest.  Dividends paid on shares of Series A Preferred Stock in an amount
less than the total amount of such dividends at the time accrued and payable on
such shares shall be allocated pro rata on a share-by-share basis among all
such shares at the time outstanding.  The Board of Directors may fix a record
date for the determination of holders of shares of Series A Preferred Stock
entitled to receive payment of a dividend or distribution declared thereon,
which record date shall not be more than 60 days prior to the date fixed for
the payment thereof.

        Section 3.  Voting Rights.  In addition to any other voting rights
required by law, the holders of shares of Series A Preferred Stock shall have
the following voting rights:

        (A)  Subject to the provision for adjustment hereinafter set forth,
each share of Series A Preferred Stock shall entitle the holder thereof to
1,000 votes on all matters submitted to a vote of stockholders of the
Corporation.  If the Corporation shall at any
 

<PAGE>   23



time after the Rights Declaration Date pay any dividend on Common Stock payable
in shares of Common Stock or effect a subdivision or combination of the
outstanding shares of Common Stock (by reclassification or otherwise) into a
greater or lesser number of shares of Common Stock, then in each such case the
number of votes per share to which holders of shares of Series A Preferred
Stock were entitled immediately prior to such event shall be adjusted by
multiplying such number by a fraction the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

        (B)  Except as otherwise provided herein or by law, the holders of
shares of Series A Preferred Stock and the holders of shares of Common Stock
shall vote together as a single class on all matters submitted to a vote of
stockholders of the Corporation.

        (C)  (i)  If at any time dividends on any Series A Preferred Stock
shall be in arrears in an amount equal to six quarterly dividends thereon, the
occurrence of such contingency shall mark the beginning of a period (herein
called a "default period") which shall extend until such time when all accrued
and unpaid dividends for all previous quarterly dividend periods and for the
current quarterly dividend period on all shares of Series A Preferred Stock
then outstanding shall have been declared and paid or set apart for payment. 
During each default period, all holders of Preferred Stock and any other series
of Preferred Stock then entitled as a class to elect directors, voting together
as a single class, irrespective of series, shall have the right to elect two
Directors.

        (ii)  During any default period, such voting right of the holders of
Series A Preferred Stock may be exercised initially at a special meeting called
pursuant to subparagraph (iii) of this Section 3(C) or at any annual meeting of
stockholders, and thereafter at annual meetings of stockholders, provided that
neither such voting right nor the right of the holders of any other series of
Preferred Stock, if any, to increase, in certain cases, the authorized number
of Directors shall be exercised unless the holders of 10% in number of shares
of Preferred Stock outstanding shall be present in person or by proxy.  The
absence of a quorum of 


<PAGE>   24


holders of Common Stock shall not affect the exercise by holders of Preferred
Stock of such voting right.  At any meeting at which holders of Preferred Stock
shall exercise such voting right initially during an existing default period,
they shall have the right, voting as a class, to elect Directors to fill such   
vacancies, if any, in the Board of Directors as may then exist up to two
Directors or, if such right is exercised at an annual  meeting, to elect two
Directors.  If the number which may be so elected at any special meeting does
not amount to the required number, the holders of the Preferred Stock shall
have the right to make such increase in the number of Directors as shall be
necessary to permit the election by them of the required number.  After the
holders of the Preferred Stock shall have exercised their right to elect
Directors in any default period and during the continuance of such period, the
number of Directors shall not be increased or decreased except by vote of the
holders of Preferred Stock as herein provided or pursuant to the rights of any
equity securities ranking senior to or pari passu with the Series A Preferred
Stock.

        (iii)  Unless the holders of Preferred Stock shall, during an existing
default period, have previously exercised their right to elect Directors, the
Board of Directors may order, or any stockholder or stockholders owning in the
aggregate not less than 10% of the total number of shares of Preferred Stock
outstanding, irrespective of series, may request, the calling of special
meeting of holders of Preferred Stock, which meeting shall thereupon be called
by the President, a Vice President or the Secretary of the Corporation.  Notice
of such meeting and of any annual meeting at which holders of Preferred Stock
are entitled to vote pursuant to this paragraph (C)(iii) shall be given to each
holder of record of Preferred Stock by mailing a copy of such notice to him at
his last address as the same appears on the books of the Corporation.  Such
meeting shall be called for a time not earlier than 20 days and not later than
60 days after such order or request or in default of the calling of such
meeting within 60 days after such order or request, such meeting may be called
on similar notice by any stockholder or stockholders owning in the aggregate
not less than 10% of the total number of shares of Preferred Stock outstanding,
irrespective of series.  Notwithstanding the provisions of this paragraph
(C)(iii), no such special meeting shall be called during the period within 60 


<PAGE>   25


days immediately preceding the date fixed for the next annual meeting of
stockholders.

        (iv)  In any default period, the holders of Common Stock, and other
classes of stock of the Corporation if applicable, shall continue to be
entitled to elect the whole number of Directors until the holders of Preferred
Stock shall have exercised their right to elect two Directors voting as a
class, after the exercise of which right (x) the Directors so elected by the
holders of Preferred Stock shall continue in office until their successors
shall have been elected by such holders or until the expiration of the default
period, and (y) any vacancy in the Board of Directors may (except as provided
in paragraph (C)(ii) of this Section 3) be filled by vote of a majority of the
remaining Directors theretofore elected by the holders of the class of stock
which elected the Director whose office shall have become vacant.  References
in this paragraph (C) to Directors elected by the holders of a particular class
of stock shall include Directors elected by such Directors to fill vacancies as
provided in clause (y) of the foregoing sentence.

        (v)  Immediately upon the expiration of a default period, (x) the right
of the holders of Preferred Stock as a class to elect Directors shall cease,
(y) the term of any Directors elected by the holders of Preferred Stock as a
class shall terminate, and (z) the number of Directors shall be such number as
may be provided for in the certificate of incorporation or bylaws irrespective
of any increase made pursuant to the provisions of paragraph (C)(ii) of this
Section 3 (such number being subject, however, to change thereafter in any
manner provided by law or in the certificate of incorporation or bylaws).  Any
vacancies in the Board of Directors effected by the provisions of clauses (y)
and (z) in the preceding sentence may be filled by a majority of the remaining
Directors.

        (D)  The Certificate of Incorporation of the Corporation shall not be
amended in any manner (whether by merger or otherwise) so as to adversely
affect the powers, preferences or special rights of the Series A Preferred
Stock without the affirmative vote of the holders of a majority of the
outstanding shares of Series A Preferred Stock, voting separately as a class.


<PAGE>   26



        (E)  Except as otherwise provided herein, holders of Series A Preferred
Stock shall have no special voting rights, and their consent shall not be
required for taking any corporate action.

        Section 4.  Certain Restrictions.

        (A)  Whenever quarterly dividends or other dividends or distributions
payable on the Series A Preferred Stock as provided in Section 2 are in
arrears, thereafter and until all accrued and unpaid dividends and
distributions, whether or not declared, on outstanding shares of Series A
Preferred Stock shall have been paid in full, the Corporation shall not:

            (i)  declare or pay dividends on, or make any other distributions 
      on, any shares of stock ranking junior (either as to dividends or upon
      liquidation, dissolution or winding up) to the Series A Preferred Stock;

            (ii)  declare or pay dividends on, or make any other distributions
      on, any shares of stock ranking on a parity (either as to dividends or 
      upon liquidation, dissolution or winding up) with the Series A Preferred
      Stock, except dividends paid ratably on the Series A Preferred Stock and
      all such other parity stock on which dividends are payable or in arrears
      in proportion to the total amounts to which the holders of all such 
      shares are then entitled;

            (iii)  redeem, purchase or otherwise acquire for value any shares of
      stock ranking junior (either as to dividends or upon liquidation,
      dissolution or winding up) to the Series A Preferred Stock; provided that
      the Corporation may at any time redeem, purchase or otherwise acquire 
      shares of any such junior stock in exchange for shares of stock of the
      Corporation ranking junior (as to dividends and upon dissolution,
      liquidation or winding up) to the Series A Preferred Stock; or
        
            (iv)  redeem, purchase or otherwise acquire for value any shares of
      Series A Preferred Stock, or any shares of stock ranking on a parity 
      (either as to dividends or upon 


<PAGE>   27


      liquidation, dissolution or winding up) with the Series A Preferred
      Stock, except in accordance with a purchase offer made in writing or by
      publication (as determined by the Board of Directors) to all holders of
      Series A Preferred Stock and all such other parity stock upon such terms
      as the Board of Directors, after consideration of the respective annual
      dividend rates and other relative rights and preferences of the
      respective series and classes, shall determine in good faith will result
      in fair and equitable treatment among the respective series or classes.
        
        (B)  The Corporation shall not permit any subsidiary of the Corporation
to purchase or otherwise acquire for value any shares of stock of the
Corporation unless the Corporation could, under paragraph (A) of this Section
4, purchase or otherwise acquire such shares at such time and in such manner.

        Section 5.  Reacquired Shares.  Any shares of Series A Preferred Stock
redeemed, purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and canceled promptly after the acquisition
thereof.  All such shares shall upon their cancellation become authorized but
unissued shares of Preferred Stock without designation as to series and may be
reissued as part of a new series of Preferred Stock to be created by resolution
or resolutions of the Board of Directors as permitted by the Certificate of
Incorporation or as otherwise permitted under Delaware Law.

        Section 6.  Liquidation, Dissolution or Winding Up.  Upon any
liquidation, dissolution or winding up of the Corporation, no distribution
shall be made (1) to the holders of shares of stock ranking junior (either as
to dividends or upon liquidation, dissolution or winding up) to the Series A
Preferred Stock unless, prior thereto, the holders of shares of Series A
Preferred Stock shall have received $1.00 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not
declared, to the date of such payment; provided that the holders of shares of
Series A Preferred Stock shall be entitled to receive an aggregate amount per
share, subject to the provision for adjustment hereinafter set forth, equal to
1,000 times the aggregate amount to be distributed per share to holders of
Common 


<PAGE>   28


Stock, or (2) to the holders of stock ranking on a parity (either as to
dividends or upon liquidation, dissolution or winding up) with the Series A
Preferred Stock, except distributions made ratably on the Series A Preferred
Stock and all such other parity stock in proportion to the total amounts to
which the holders of all such shares are entitled upon such liquidation,
dissolution or winding up.  If the Corporation shall at any time after the
Rights Declaration Date pay any dividend on Common Stock payable in shares of
Common Stock or effect a subdivision or combination of the outstanding shares
of Common Stock (by reclassification or otherwise) into a greater or lesser
number of shares of Common Stock, then in each such case the aggregate amount
to which holders of shares of Series A Preferred Stock were entitled
immediately prior to such event under the proviso in clause (1) of the
preceding sentence shall be adjusted by multiplying such amount by a fraction
the numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

        Section 7.  Consolidation, Merger, etc.  If the Corporation shall enter
into any consolidation, merger, combination or other transaction in which the
shares of Common Stock are exchanged for or changed into other stock or
securities, cash or any other property, then in any such case the shares of
Series A Preferred Stock shall at the same time be similarly exchanged for or
changed into an amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 1,000 times the aggregate amount of stock,
securities, cash or any other property, as the case may be, into which or for
which each share of Common Stock is changed or exchanged.  If the Corporation
shall at any time after the Rights Declaration Date pay any dividend on Common
Stock payable in shares of Common Stock or effect a subdivision or combination
of the outstanding shares of Common Stock (by reclassification or otherwise)
into a greater or lesser number of shares of Common Stock, then in each such
case the amount set forth in the preceding sentence with respect to the
exchange or change of shares of Series A Preferred Stock shall be adjusted by
multiplying such amount by a fraction the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and 


<PAGE>   29


the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

        Section 8.  No Redemption.  The Series A Preferred Stock shall not be
redeemable.

        Section 9.  Rank.  The Series A Preferred Stock shall rank junior (as
to dividends and upon liquidation, dissolution and winding up) to all other
series of the Corporation's preferred stock except any series that specifically
provides that such series shall rank junior to the Series A Preferred Stock.

        Section 10.  Fractional Shares.  Series A Preferred Stock may be issued
in fractions of a share which shall entitle the holder, in proportion to such
holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of
holders of Series A Preferred Stock.

evidences of indebtedness of this Company ("Securities") in one or more series
under such Indenture; and

      WHEREAS, capitalized terms used in these resolutions and not otherwise
defined are used with the same meaning ascribed to such terms in the Indenture;

      THEREFORE RESOLVED, that there is established a series of Securities
under the Indenture, the terms of which shall be as follows:

            1.    The Securities of such series shall be designated as the

which may be authenticated and delivered under the Indenture is limited to Two
Hundred Million Dollars ($200,000,000), except for Securities of such series
authenticated and delivered upon registration of, transfer of, or in exchange
for, or in lieu of, other Securities of such series pursuant to Sections 2.07,

<PAGE>   2
for payment.  The March 1 or September 1 (whether or not a business day), as
the case may be, next preceding each such interest payment date shall be the
"record date" for the determination of holders to whom interest is payable.

            5.     The principal of and the interest on the Securities of such
series shall be payable at the office or agency of this Company maintained for
such purpose under Section 3.02 of the Indenture in the Borough of Manhattan,

the address of the person entitled thereto as such address shall appear on the
Company's registry books.

            6.    The Securities of such series shall not be redeemable prior

                               MASCO CORPORATION
                      6 5/8% NOTE DUE SEPTEMBER 15, 1999
      This Note is one of a duly authorized issue of debentures, notes,
bonds or other evidences of indebtedness of the Company (hereinafter called the
"Securities") of the series hereinafter specified, all issued or to be issued
under and pursuant to an indenture dated as of December 1, 1982 (herein called
the "Indenture"), duly executed and delivered by the Company to Morgan Guaranty
Trust Company of New York, Trustee (herein called the "Trustee"), to which
Indenture and all indentures supplemental thereto reference is hereby made for
a description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company and holders of the
Securities.  The Securities may be issued in one or more series, which
different series may be issued in various aggregate principal amounts, may
mature at different times, may bear interest (if any) at different rates, may
be subject to different redemption provisions (if any), may be subject to
different sinking, purchase or analogous funds (if any), may be subject to
different covenants and Events of Default and may otherwise vary as in the
Indenture provided.  This Note is one of a series designated as the 6 5/8%
Notes Due September 15, 1999 of the Company, limited in aggregate principal
amount to $200,000,000.
      In case an Event of Default with respect to the 6 5/8% Notes Due
September 15, 1999 shall have occurred and be continuing, the principal hereof
may be declared, and upon such declaration shall become, due and payable, in
the manner, with the effect and subject to the conditions provided in the
Indenture.
      The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the holders of not less than 66 2/3% in aggregate principal
amount of the Securities at the time outstanding of all series to be affected
(voting as a class), evidenced as in the Indenture provided, to execute
supplemental indentures adding any provisions to or changing in any manner or
eliminating any of the provisions of the Indenture or of any supplemental
indenture or modifying in any manner the rights of the holders of the
Securities of each such series; provided, however, that no such supplemental
indenture shall (i) extend the final maturity of any Security, or reduce the
rate or extend the time of payment of interest thereon, or reduce the principal
amount thereof or any premium thereon, or reduce any amount payable on
redemption thereof or make the principal thereof or any interest or premium
thereon payable in any coin or currency other than that hereinbefore provided,
or impair or affect the right of any holder to institute suit for payment
thereof or the right of repayment, if any, at the option of the holder, without
the consent of the holder of each Security so affected, or (ii) reduce the
aforesaid principal amount of Securities of all series to be affected, the
holders of which are required to consent to any such supplemental indenture,
without the consent of the holders of all Securities so affected then
outstanding.  It is also provided in the Indenture that, with respect to
certain defaults or Events of Default regarding the Securities of any series,
prior to any declaration accelerating the maturity of such Securities, the
holders of a majority in aggregate principal amount of the Securities of such
series at the time outstanding (or, in the case of certain defaults or Events
of Default, all the Securities) may on behalf of the holders of all of the
Securities of such series (or all the Securities, as the case may be) waive any
such past default or Event of Default under the Indenture and its consequences
except a default in the payment of principal of, premium, if any, or interest,
if any, on any of the Securities.  Any such consent or waiver by the holder of
this Note (unless revoked as provided in the Indenture) shall be conclusive and
binding upon such holder and upon all future holders and owners of this Note
and any Notes which may be issued in exchange or transfer hereof or in
substitution herefor, irrespective of whether or not any notation thereof is
made upon this Note or such other Notes.
      No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this Note
at the place, at the respective times, at the rate and in the coin or currency
herein prescribed.
      The Notes are issuable in registered form without coupons in
denominations of $1,000 and any multiple of $1,000.  Upon due presentment for
registration of transfer of this Note at the office or agency of the Company
for such registration in the Borough of Manhattan, The City of New York, or any
other location or locations as may be provided for pursuant to the Indenture, a
new Note or Notes of authorized denominations for an equal aggregate principal
amount will be issued to the transferee in exchange therefor, subject to the
limitations provided in the Indenture, without charge except for any tax or
other governmental charge imposed in connection therewith.

      The Notes may not be redeemed prior to maturity.  
      The Company, the Trustee and any agent of the Company or the Trustee may
deem and treat the holder hereof as the absolute owner of this Note (whether or
not this Note shall be overdue and notwithstanding any notation of ownership or
other writing hereon), for the purpose of receiving payment of or on account of
the principal hereof and, subject to the provisions on the face hereof,
interest hereon, and for all other purposes, and neither the Company nor the
Trustee nor any such agent shall be affected by any notice to the contrary.
All payments made to or upon the order of such holder shall, to the extent of
the sum or sums paid, effectually satisfy and discharge liability for moneys
payable on this Note.
      No recourse for the payment of the principal of, or premium, if any, or
interest on this Note, or for any claim based hereon or otherwise in respect
hereof, and no recourse under or upon any obligation, covenant or agreement of
the Company in the Indenture or any indenture supplemental thereto or in any
Note, or because of the creation of any indebtedness represented thereby, shall
be had against any incorporator, stockholder, officer or director, as such,
past, present or future, of the Company or of any successor corporation, either
directly or through the Company or any successor corporation, whether by virtue
of any constitution, statute or rule of law or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issue hereof, expressly waived
and released.
      All terms used in this Note which are defined in the Indenture shall have
the respective meanings ascribed to them therein.
      This Note shall be deemed to be a contract made under the laws of the

                          Subject:    Amendment No I to Masco Corporation's 
                                      Amended and Restated Credit Agreement 
                                      dated as of November 14, 1996


        It has come to our attention that an erroneous cross-reference exists
in Masco Corporation's $750,000,000 Amended and Restated Credit Agreement dated
as of November 14, 1996.  Specifically, Section 3.02(d) which requires that all
representations and warranties be true for All Borrowings incorrectly refers to
Section 4.04(b) rather than 4.04(c) for the material adverse change exception
relating to Refunding Borrowings.

        Section 3.02(d) n the 1996 Amended and Restated Agreement inadvertently
continued to cross reference Section 4.04(b) which was changed in the Amendment
to address interim financial statements.  The material adverse change clause
which was formerly Section 4.04(b) became Section 4.04(c).

        Please sign a copy of this letter in the space provided below to
confirm your agreement to amend the 1996 Amended and Restated Credit Agreement
to correct the erroneous cross-reference by changing 4.04(b)" to "4.04(c)" in
Section 3.02(d).  We would appreciate your returning this letter to Patricia
Lunka by facsimile at (212)648-5336 no later than Friday, May 9, 1997.  Should
you have any questions, please do not hesitate to call Patricia Lunka at
(212)648-7457.  We will send you notification of the effectiveness of Amendment
No. I following receipt of signature pages by the Required Banks. Thank you in
advance for attending to this matter.

                                                   Very truly yours,

                                                   /s/Patricia Lunka

continue with its existing principal amount, interest rate and Interest Period,
except that each such Existing Bid-Option Loan shall be deemed a Bid-Option

Agreement.


                                ARTICLE III.

                   THE LOANS AND LETTER OF CREDIT ISSUANCES

        3.1   Revolving Loans.  Each Bank agrees, for itself only, subject to
the terms and conditions set forth in this Agreement, to make Revolving Loans
in Dollars to any Borrower from time to time from the Closing Date to but
excluding the Termination Date; provided that the aggregate outstanding
principal amount of such Bank's Revolving Loans shall not at any time exceed
the excess of (a) the amount of its Revolving Credit Commitment, over (b) the
sum of (i) its Revolving Credit 




                                       24


<PAGE>   32

Commitment Percentage of the Letter of Credit Obligations Amount plus
(ii) its Revolving Credit Commitment Percentage of the aggregate outstanding
principal balance of the Swing Line Loans plus (iii) its Revolving Credit
Commitment Percentage of the Dollar Equivalent of the aggregate outstanding
principal amount of all Bid-Option Loans made by the Banks (using for purposes
of such determination, in the case of any Alternate Currency Loans, the Dollar
Equivalent as determined on the last Business Day of the month then most
recently ended); provided, however, that at no time shall the aggregate
outstanding principal balance of the Revolving Loans, Swing Line Loans,
Alternate Currency Loans, Bid-Option Loans and Letter of Credit Obligations
exceed $800,000,000.  Each Eurodollar Borrowing shall be in an aggregate
principal amount of $10,000,000 or any larger multiple of $5,000,000 and each
Floating Rate Borrowing shall be in an aggregate principal amount of $5,000,000
or any larger multiple of $5,000,000; provided that any such Borrowing may be
in the aggregate amount of the unused Revolving Credit Commitments.  Each such
Borrowing shall be made by the several Banks ratably in accordance with their
respective Revolving Credit Commitment Percentages.  Within the foregoing
limits, each Borrower may borrow Revolving Loans under this Section 3.1, repay
such Revolving Loans, prepay such Loans to the extent permitted or required by
this Agreement and reborrow under this Section 3.1.  Default by any Bank with
respect to its obligations hereunder shall not excuse any non-performance by
any other Bank, provided that no Bank shall be liable for the non-performance
by any other Bank of its obligations hereunder. 

        3.2   Term Loans.       

              Subject to the terms and conditions set forth in this Agreement, 
each Bank on the Closing Date severally and not jointly agrees to make
a term loan, in Dollars, to one or more of the Borrowers in an aggregate amount
not to exceed such Bank's Term Loan Commitment (each individually, a "Term
Loan" and, collectively, the "Term Loans").  All Term Loans shall be made by
the Banks on the Closing Date simultaneously and pro rata, it being understood
that no Bank shall be responsible for any failure by any other Bank to perform
its obligation to make any Term Loan hereunder nor shall the Term Loan
Commitment of any Bank be increased or decreased as a result of any such
failure.

        3.3   Letters of Credit.

              (a)   Subject to the terms and conditions set forth in this
Agreement, the Administrative Agent agrees to issue for the account of and
upon the application of any of the Borrowers, and each Bank further agrees for
itself only to participate in the risk of, Letters of Credit from time to time
from the Closing Date to but excluding the Termination Date; provided that the
Letter of Credit Obligations Amount shall not at any time exceed the lesser of
(i) $150,000,000 and (ii) the excess of (A) the aggregate amount of the
Revolving Credit Commitments over (B) the aggregate outstanding principal
amount of the Revolving Loans plus the outstanding principal amount of the
Swing Line Loans plus the outstanding principal balance of the Bid-Option Loans
plus the aggregate outstanding principal amount of the Alternate Currency
Syndicated Loans.  No Letter of Credit shall have a stated expiry date earlier
than 30 days after the date of its issuance, and no Letter of Credit shall have
a stated expiry date or, if by its terms it is periodically renewable, be
subject to being terminated by the Administrative Agent (unless renewal is
permitted by the Administrative Agent in its sole discretion, in which case the
Administrative Agent will not permit renewal to a date beyond that 


                                       25


<PAGE>   33

determined in accordance with the following portion of this sentence),
later than the earlier of (i) the one year anniversary of its issuance (or, if
renewable and renewal has been permitted, the one year anniversary of its last
renewal) and (ii) the fifth Business Day before the Scheduled Expiration Date. 
Each Letter of Credit shall be in a minimum amount of $1,000,000 or as
otherwise agreed to by the Administrative Agent.  Subject to the terms and
conditions set forth in this Agreement, the Administrative Agent shall, on the
date any Letter of Credit is requested to be issued, issue the related Letter
of Credit for the pro rata risk of the Banks.  Notwithstanding anything herein
to the contrary, the Administrative Agent may decline to issue any Letter of
Credit if the beneficiary or the conditions of drawing are reasonably
unacceptable to the Administrative Agent, or if the purpose of issuance is
illegal or is in contravention of any law, rule, regulation or public policy or
any judgment, decree, writ, injunction, order or award of any arbitrator, court
or governmental authority.

              (b)   The applicable Borrower shall give the Administrative Agent
written notice in substantially the form attached hereto as Exhibit D (a
"Request for Letter of Credit Issuance") not later than 10:00 a.m. (Detroit
time) on the fifth Business Day before each requested Letter of Credit Issuance
or such later time as is acceptable to the Administrative Agent.

              (c)   The applicable Borrower agrees (i) to pay to the
Administrative Agent for the account of the Banks a fee computed at the per
annum rate equal to the Applicable Margin for Letters of Credit based on the
maximum amount available to be drawn from time to time under the related Letter
of Credit for the period from and including the date of such Letter of Credit
Issuance to but excluding the stated expiry date of such Letter of Credit, and
(ii) to pay an additional fee to the Administrative Agent for its own account
computed at the rate of one-eighth of one percent (1/8 of 1%) per annum of such
maximum amount for such period, such fees with respect to any Letter of Credit
to be paid quarterly in arrears, in each case with respect to each calendar
quarter or portion thereof not later than the tenth day after the end of each
March, June, September and December, commencing with the first such calendar
quarter-end after the Closing Date, and on the Termination Date, based upon the
Applicable Margin for Letters of Credit in effect from time to time during such
period.  The applicable Borrower further agrees to pay to the Administrative
Agent, on demand, such other customary administrative fees, charges and expenses
of the Administrative Agent in respect of the issuance, negotiation, acceptance,
amendment, transfer and payment of such Letter of Credit or otherwise payable
pursuant to the application and related documentation under which such Letter of
Credit is issued.

              (d)   Nothing in this Agreement shall be construed to require or
authorize any Bank to issue any Letter of Credit, it being recognized that the
Administrative Agent has the sole obligation under this Agreement to issue
Letters of Credit for the risk of the Banks.  Upon each Letter of Credit
Issuance, each Bank shall automatically acquire a pro rata risk participation
interest in the related Letter of Credit based on its respective Revolving
Credit Commitment Percentage.  If the Administrative Agent shall honor a draft
or other demand for payment presented or made under any Letter of Credit, the
Administrative Agent shall provide notice thereof to each Bank on the date such
draft or demand is honored unless the applicable Borrower shall have satisfied
its reimbursement obligation under subsection (e) of this Section 3.3 by payment
to the Administrative Agent on such date.  Each Bank, 

                                       26

<PAGE>   34

on such date, shall make an amount equal to its Revolving Credit        
Commitment Percentage of the amount paid by the Administrative Agent available
in immediately available funds at the principal office of the Administrative
Agent for the account of the Administrative Agent.  If and to the extent such
Bank shall not have made such amount available to the Administrative Agent,
such Bank and the applicable Borrower severally agree to pay to the
Administrative Agent forthwith on demand such amount, together with interest
thereon for each day from the date such amount was paid by the Administrative
Agent until such amount is so made available to the Administrative Agent at (i)
in the case of such Bank, the Federal Funds Rate and (ii) in the case of the
applicable Borrower, the per annum rate equal to the interest rate applicable
during such period to the related Borrowing deemed (or that could have been
deemed) disbursed under subsection (e) of this Section 3.3 in respect of the
reimbursement obligation of the applicable Borrower.  If such Bank shall pay
such amount to the Administrative Agent together with such interest, if any,
accrued, such amount so paid shall constitute a Revolving Loan by such Bank as
part of the Borrowing disbursed in respect of the reimbursement obligation of
the applicable Borrower under subsection (e) of this Section 3.3 for purposes
of this Agreement.  The failure of any Bank to make an amount equal to its
Revolving Credit Commitment Percentage of any such amount paid by the
Administrative Agent available to the Administrative Agent shall not relieve
any other Bank of its obligation to make available an amount equal to such
other Bank's Revolving Credit Commitment Percentage of such amount, but no Bank
shall be responsible for failure of any other Bank to make its share available
to the Administrative Agent.

              (e)(i) Whether a Letter of Credit was issued for the account of 
any Borrower or any Consolidated Subsidiary of such Borrower, and without 
limiting the reimbursement obligation of such other Consolidated Subsidiary, 
such Borrower agrees to pay to the Administrative Agent, not later than 
3:00 p.m. (Detroit time) on the date on which the Administrative Agent
shall honor a draft or other demand for payment presented or made under such 
Letter of Credit, an amount equal to the amount paid by the Administrative
Agent in respect of such draft or other demand under such Letter of Credit and
all expenses paid or incurred by the Administrative Agent relative thereto (the
"Reimbursement Amount").  The Administrative Agent shall, on the date of each
demand for payment under any Letter of Credit, give such Borrower notice
thereof and of the amount of such Borrower's reimbursement obligation and
liability for expenses relative thereto; provided that the failure of the
Administrative Agent to give such notice shall not affect the reimbursement and
other obligations of such Borrower under this Section 3.3.  Unless such
Borrower shall have made such payment to the Administrative Agent on such day,
upon each such payment by the Administrative Agent, such Borrower shall be
deemed to have elected to satisfy its reimbursement obligation by a Floating
Rate Borrowing of a Revolving Loan in an amount equal to the amount so paid by
the Administrative Agent in respect of such draft or other demand under such
Letter of Credit, and the Administrative Agent shall be deemed to have
disbursed to such Borrower, for the account of the Banks, the Revolving Loans
comprising such Floating Rate Borrowing, and each Bank shall make its share of
each such Floating Rate Borrowing available to the Administrative Agent in
accordance with Section 3.7(d).  Such Revolving Loans shall be deemed disbursed
notwithstanding any failure to satisfy any conditions for disbursement of any
Loan set forth in Article VIII and, to the extent of the Revolving Loans so
disbursed, the reimbursement obligation of such Borrower under this subsection
(e)(i) shall be deemed satisfied.


                                       27


<PAGE>   35

                    (ii)  If, for any reason (including without limitation as a
result of the occurrence of an Event of Default with respect to any of the
Borrowers pursuant to Section 9.1(f) or (g)), Revolving Loans may not be made by
the Banks as described in Section 3.3(e)(i), then (A) such Borrower agrees that
each Reimbursement Amount not paid pursuant to the first sentence of Section
3.3(e)(i) shall bear interest, payable on demand by the Administrative Agent, at
the interest rate then applicable to Revolving Loans, and (B) effective on the
date each such Revolving Loans would otherwise have been made, each Bank
severally agrees that it shall unconditionally and irrevocably, without regard
to the occurrence of any Default, to the extent of such Bank's Revolving Credit
Commitment Percentage, purchase a participating interest in each Reimbursement
Amount.  Each Bank will immediately transfer to the Administrative Agent, in
same day funds, the amount of its participation.  Each Bank shall share on a pro
rata basis (calculated by reference to its Revolving Credit Commitment
Percentage) in any interest which accrues thereon and in all repayments 
thereof.   If and to the extent that any Bank shall not have so made the
amount of such participating interest available to the Administrative Agent,
such Bank agrees to pay to the Administrative Agent forthwith on demand such
amount together with interest thereon, for each day from the date of demand by 
the Administrative Agent until the date such amount is paid to the 
Administrative Agent, at the Federal Funds Rate.

              (f)   The reimbursement obligation of the Borrowers under this
Section 3.3 with respect to each Letter of Credit shall be absolute,
unconditional and irrevocable and shall remain in full force and effect until
all such obligations of the Borrowers to the Banks and the Administrative Agent
with respect to such Letter of Credit shall have been satisfied, and such
obligations of the Borrowers shall not be affected, modified or impaired upon
the happening of any event, including without limitation, any of the following,
whether or not with notice to, or the consent of, the Borrowers:

              (i)   Any lack of validity or enforceability of any Letter of 
        Credit or any documentation relating to any Letter of Credit or to any
        transaction related in any way to such Letter of Credit (the "Letter of
        Credit Documents");

             (ii)   Any amendment, modification, waiver, consent, or any
        substitution, exchange or release of or failure to perfect any interest 
        in collateral or security, with respect to any of the Letter of Credit
        Documents;

            (iii)   The existence of any claim, setoff, defense or other right
        which the Borrowers may have at any time against any beneficiary or any
        transferee of any Letter of Credit (or any persons or entities for whom
        any such beneficiary or any such transferee may be acting), the
        Administrative Agent or any Bank or any other Person, whether in
        connection with any of the Letter of Credit Documents, the transactions
        contemplated herein or therein or any unrelated transactions;

             (iv)   Any draft or other statement or document presented under any
        Letter of Credit proving to be forged, fraudulent, invalid or 
        insufficient in any respect or any statement therein being untrue or
        inaccurate in any respect;



                                       28
<PAGE>   36

              (v)   Payment by the Administrative Agent to the beneficiary under
        any Letter of Credit against presentation of documents which do not 
        comply with the terms of the Letter of Credit, including failure
        of any documents to bear any reference or adequate reference to such 
        Letter of Credit;

             (vi)   Any failure, omission, delay or lack on the part of the
        Administrative Agent or any Bank or any party to any of the Letter of
        Credit Documents to enforce, assert or exercise any right, power or 
        remedy conferred upon the Administrative Agent, any Bank or any
        such party; or

            (vii)   Any other event or circumstance that would, in the absence 
        of this clause, result in the release or discharge by operation of law 
        or otherwise of the Borrowers from the performance or observance of any
        obligation, covenant or agreement contained in this Section 3.3.

No setoff, counterclaim, reduction or diminution of any obligation or any
defense of any kind or nature which the Borrowers have or may have against the
beneficiary of any Letter of Credit shall be available hereunder to the
Borrowers against the Administrative Agent or any Bank.  Nothing in this
Section 3.3 shall limit the liability, if any, of the Administrative Agent to
the Borrowers pursuant to Section 11.5(c).

        3.4   Bid-Option Borrowings.

              (a)   The Bid-Option. In addition to Syndicated Borrowings that 
are made pursuant to Sections 3.1 and 3.2, so long as the most recently
determined Senior Debt Coverage Ratio is less than 3.0 to 1.0 (except as
provided in Article II with respect to Existing Bid-Option Loans), the
Borrowers may, as set forth in this Section, from time to time after the
Closing Date to but excluding the Termination Date request the Banks to offer
to make Bid-Option Loans to any one or more of the Borrowers.  Each Bank may,
but shall have no obligation to, make such offers; furthermore, each Bank may
limit the aggregate amount of Bid-Option Loans when quoting rates for more
than one Bid-Option Interest Period in any Bid-Option Quote, provided that such
limitation shall not be less than the minimum amounts required hereunder for
Bid-Option Loans and the applicable Borrower may choose among the Bid-Option
Loans if such limitation is imposed.  The applicable Borrower may, but shall
have no obligation to, accept any such offers, in the manner set forth in this
Section; provided that the Dollar Equivalent of the aggregate outstanding
principal amount of Bid-Option Loans (using for purposes of such determination,
in the case of any Alternate Currency Loans, the Dollar Equivalent determined
on the last Business Day of the month then most recently ended) shall not, at
any time exceed the lesser of (i) the excess of (A) the aggregate amount of the
Revolving Credit Commitments over (B) the sum of the aggregate outstanding
principal amount of Revolving Loans plus the Letter of Credit Obligations
Amount plus the outstanding principal balance of the Swing Line Loans plus the
outstanding principal balance of the Alternate Currency Syndicated Loans, or
(ii) fifty percent (50%) of the sum of the aggregate amount of the Revolving
Credit Commitments and the aggregate principal amount of the Term Loans (as the
same may be reduced in accordance with the terms of this 




                                       29


<PAGE>   37

Agreement during any applicable Bid-Option Interest Period); and        
provided, further, that the Dollar Equivalent of the aggregate outstanding
principal amount of Alternate Currency Bid-Option Loans shall not exceed
$200,000,000 (when taken together with the Alternate Currency Syndicated
Loans).

              (b)   Bid-Option Quote Requests.  When the applicable Borrower
wishes to request offers to make Bid-Option Loans under this Section, it shall
transmit to the Administrative Agent by telex or telecopy a request
substantially in the form attached hereto as Exhibit E (a "Bid-Option Quote

the fifth Business Day next preceding the date of the Borrowing in the case of a
Bid-Option Auction for Eurodollar Rate Bid-Option Loans, or (iii) the fifth

Bid-Option Auction for Alternate Currency Bid-Option Loans, specifying:

                    (A)   the proposed date of the Borrowing, which shall
                    be a Business Day;

                    (B)   whether the Borrowing is to be an Absolute Rate
                    Dollar Bid-Option Borrowing, a Eurodollar Rate Bid-Option
                    Borrowing or an Alternate Currency Bid-Option Borrowing
                    and, if an Alternate Currency Bid-Option Borrowing, the
                    desired Alternate Currency;

                    (C)   the aggregate amount of such Borrowing, which shall
                    be (A) $25,000,000 or a larger multiple of $5,000,000,
                    in the case of a Dollar Bid-Option Borrowing, or (B) not
                    less than the Dollar Equivalent of $5,000,000, in the case
                    of a Alternate Currency Bid-Option Borrowing; and

                    (D)   the duration of the Interest Period applicable
                    thereto, subject to the provisions of the definition of
                    the applicable Interest Period.

The Borrowers may request offers to make Bid-Option Loans for more than one     
Interest Period in a single Bid-Option Quote Request.  The Borrowers may not
request offers to make Bid-Option Loans in more than one currency in any Bid-
Option Quote Request and may not make more than five Bid-Option Borrowings
during any month without the consent of the Administrative Agent.

              (c)   Invitation for Bid-Option Quotes.  Promptly upon receipt of 
a Bid-Option Quote Request, the Administrative Agent shall send to the Banks by
telex or telecopy (or telephone promptly confirmed by telex or telecopy) an
Invitation for Bid-Option Quotes substantially in the form attached hereto as
Exhibit F, which shall constitute an invitation by the applicable Borrower to

                    Bank, (2) must be (y) in the case of any Dollar Bid-        
                    Option Loan, $5,000,000 or a larger multiple thereof,
                    or (z) in the case of any Alternate Currency Bid-Option 
                    Loan, not less than $1,000,000, and (3) may not 
                    exceed the Dollar Equivalent of the aggregate principal 
                    amount of the Bid-Option Borrowing specified in the 
                    related Invitation for Bid-Option Quotes;

                    (D)   in the case of a Bid-Option Auction for       
                    Absolute Rate Dollar Bid-Option Loans or Alternate 
                    Currency Bid-Option Loans, the rate of interest per annum
                    (the "Bid-Option Absolute Rate") offered for each such
                    Bid-Option Loan;

                    (E)   in the case of a Bid-Option Auction for  Eurodollar
                    Rate Bid-Option Loans, the applicable margin, which
                    may be positive or negative (the "Bid-Option Eurodollar
                    Rate Margin"), expressed as a  percentage, offered for each
                    such Bid-Option Loan;

                    (F)   the Interest Period(s) for which each such Bid-       
                    Option Absolute Rate or Bid-Option Eurodollar Rate Margin,
                    as the case may be, is offered; and

                    (G)   the identity of the quoting Bank.

                    (iii) Any Bid-Option Quote shall be disregarded if it:

                    (A)   is not substantially in the form of Exhibit G         
                    hereto or does not specify all of the information  required
                    by subsection (d)(ii) above;

                    (B)   contains qualifying, conditional or similar language;

                    (C)   proposes terms other than or in addition to those

                    (D)   arrives after the time set forth in subsection (d)(i);















                                       32



<PAGE>   40

provided that a Bid-Option Quote shall not be disregarded pursuant to
clause (B) or (C) above solely because it indicates that an allocation that
might otherwise be made to it pursuant to Section 3.4(g) would be unacceptable.

              (e)   Notice to Borrowers.  The Administrative Agent shall 
promptly notify the applicable Borrower of the terms (i) of any
Bid-Option Quote submitted by a Bank that is in accordance with subsection (d)
of this Section and (ii) of any Bid-Option Quote that amends, modifies or is
otherwise inconsistent with a previous Bid-Option Quote submitted by such Bank
with respect to the same Bid-Option Quote Request.  Any such subsequent
Bid-Option Quote shall be disregarded by the Administrative Agent unless such
subsequent Bid-Option Quote is submitted solely to correct a manifest error in
such former Bid-Option Quote.  The Administrative Agent's notice to the
applicable Borrower shall specify (i) the Dollar Equivalent of the aggregate
principal amount of Bid-Option Loans for which offers have been received for
each Interest Period specified in the related Bid-Option Quote Request and (ii)
the respective Dollar Equivalent of the principal amounts and respective
Bid-Option Absolute Rates or Bid-Option Eurodollar Rate Margins, as the case
may be, so offered.  

              (f)   Acceptance and Notice by Borrowers.  Not later than 
10:00 a.m. (Detroit time) on (i) the proposed date of the Borrowing, in the
case of a Bid-Option Auction for Absolute Rate Dollar Bid-Option Loans, (ii)
the third Business Day prior to the proposed date of the Borrowing, in the
case of a Bid-Option Auction for Eurodollar Rate Bid-Option Loans, or (iii) the
second Business Day prior to the proposed date of the Borrowing, in the
case of a Bid-Option Auction for Alternate Currency Bid-Option Loans, the
applicable Borrower shall notify the Administrative Agent of its acceptance or
non-acceptance of the offers so notified to it pursuant to subsection (e) of 
this Section 3.4.  In the case of acceptance, such notice (a "Notice of 
Bid-Option Borrowing") shall specify the aggregate principal amount of accepted 
offers for the applicable Interest Period(s).  The applicable Borrower may 
accept any Bid-Option Quote in whole or in part; provided that:

                    (A)   the Dollar Equivalent of the aggregate principal      
                    amount of each Bid-Option Borrowing may not exceed  the
                    applicable amount set forth in the related Bid-Option Quote
                    Request;

                    (B)   the Dollar Equivalent of the aggregate principal  
                    amount of each Bid-Option Borrowing must be (1) in the case 
                    of Dollar Bid-Option Borrowings,  $25,000,000 or a larger 
                    multiple of $5,000,000, unless the aggregate amount of the 
                    related Bid-Option Loans for which Bid-Option Quotes were 
                    received is less than $25,000,000, in which case the 
                    aggregate principal amount of the Dollar Bid-Option 
                    Borrowing may be any amount less than $25,000,000, and (2) 
                    in the case of Alternate Currency Bid-Option Loans, not 
                    less than $5,000,000 (or, if less, the aggregate amount of 
                    the 



                                     33
<PAGE>   41
                    related Bid-Option Loans for which Bid-Option Quotes were 
                    received);

                    (C)   acceptance of offers may only be made on the basis
                    of ascending Bid-Option Absolute Rates or Bid-Option
                    Eurodollar Rate Margins, as the case may be;  and

                    (D)   a Borrower may not accept any offer that is   
                    described in clause (iii) of subsection (d) of this Section 
                    or that otherwise fails to comply with the requirements  of
                    this Agreement.

              (g)   Allocation by Administrative Agent.  If offers are made by 
two or more Banks with the same Bid-Option Absolute Rates or Bid-Option 
Eurodollar Rate Margins, as the case may be, for a greater aggregate
principal amount than the amount in respect of which offers are accepted for the
related Interest Period, the principal amount of Bid-Option Loans in respect of
which such offers are accepted shall be allocated by the Administrative Agent 
among such Banks as nearly as possible (in such multiples, not greater than the
Dollar Equivalent of $500,000, as the Administrative Agent may deem 
appropriate) in proportion to the aggregate principal amount of such offers 
(excluding any Bank that has indicated in its offer that an allocation which 
otherwise would be made to it is unacceptable).   Determinations by the 
Administrative Agent of the amounts of Bid-Option Loans shall be conclusive in 
the absence of manifest error.

        3.5   Swing Line Loans.  (a)  Amount of Swing Line Loans.  Upon the
satisfaction of the conditions precedent set forth in Sections 8.1 8.2 and 8.3,
from and including the date of this Agreement and prior to the Termination
Date, the Swing Line Bank agrees, on the terms and conditions set forth in this
Agreement, to make Swing Line Loans in Dollars to the Borrowers from time to
time in an amount not to exceed the lesser of (i) $25,000,000 (minus the
outstanding principal balance of all Swing Line Loans then outstanding) or (ii)
an amount equal to the aggregate amount of the Revolving Credit Commitments
minus the outstanding principal balance of the Revolving Loans minus the Letter
of Credit Obligations Amount minus the outstanding principal balance of the
Bid-Option Loans minus the outstanding principal balance of all Swing Line
Loans at such time minus the outstanding principal balance of the Alternate
Currency Syndicated Loans at such time, in each case after giving effect to the
application of the proceeds of any Swing Line Loans made at such time (using
for purposes of such determination, in the case of any Alternate Currency
Loans, the Dollar Equivalent determined on the last Business Day of the month
then most recently ended).  Each Swing Line Loan shall be in a minimum amount
of not less than $1,000,000 (or such lesser amount as may be agreed to by the
Swing Line Bank) or an integral multiple of $1,000,000 (or such lesser amount
as may be agreed to by the Swing Line Bank) in excess thereof, and all interest
payable on the Swing Line Loans shall be payable to the Swing Line Bank for its
account.



                                       34


<PAGE>   42

              (b)  Borrowing Notice.  The applicable Borrower shall deliver to 
the Administrative Agent and the Swing Line Bank a Borrowing Notice
in substantially the form attached hereto as Exhibit C-2 ("Notice of Swing Line
Borrowing") signed by it not later than 2:00 p.m. (Detroit time) (or such
later time as shall be agreed upon between such Borrower and the Swing Line
Bank) on the Borrowing Date of each Swing Line Loan specifying (i) the
applicable Borrowing Date (which shall be a Business Day) and (ii) the aggregate
amount of the requested Swing Line Loan.  The Swing Line Loans shall at all
times be at rates agreed to between the applicable Borrower and the Swing Line
Bank.

              (c)  Repayment of Swing Line Loans.  The Swing Line Loans shall be
evidenced by the Swing Line Loan Notes and each Swing Line Loan shall be paid in
full on or before the sixth Business Day after the Borrowing Date for such Swing
Line Loan (or such longer period as may be agreed to by the Swing Line Bank). 
Outstanding Swing Line Loans may be repaid from the proceeds of Revolving Loans
or Swing Line Loans.  Any repayment of a Swing Line Loan shall be accompanied by
accrued interest thereon and shall be in the minimum amount of $1,000,000 (or
such lesser amount as may be agreed to by the Swing Line Bank) and in increments
of $1,000,000 (or such lesser amount as may be agreed to by the Swing Line Bank)
in excess thereof or the full amount of such Swing Line Loan.  If the applicable
Borrower at any time fails to repay a Swing Line Loan on the applicable date
when due, the applicable Borrower shall be deemed to have elected to borrow a
Floating Rate Loan under Section 3.1 as of such date equal in amount to the
unpaid amount of such Swing Line Loan (notwithstanding the minimum amount of
Floating Rate Loans as provided in Section 3.1).  The proceeds of any such Loan
shall be used to repay such Swing Line Loan.  Unless the Administrative Agent
upon the request of or with the consent of the Required Banks shall have
notified the Swing Line Bank prior to making any Swing Line Loan, that the
applicable conditions precedent set forth in Article VIII have not then been
satisfied, each Bank's obligation to make Loans pursuant to Section 3.1 and to
repay such Swing Line Loan pursuant to this Section 3.5 shall be unconditional,
continuing, irrevocable and absolute and shall not be affected by any
circumstances, including the occurrence or continuance of a Default.  In
the event that any Bank fails to make payment to the Administrative Agent of
any amount due under this Section 3.5(c), the Administrative Agent shall be
entitled to receive, retain and apply against such obligation the principal and
interest otherwise payable to such Bank hereunder until the Administrative
Agent receives such payment from such Bank or such obligation is otherwise
fully satisfied.  In addition to the foregoing, if for any reason any Bank
fails to make payment to the Administrative Agent of any amount due under this
Section 3.5(c), such Bank shall be deemed, at the option of the Administrative
Agent, to have unconditionally and irrevocably purchased from the Swing Line
Bank, without recourse or warranty, an undivided interest in and participation
in the Swing Line Loan in the amount of the Loan such Bank was required to make
pursuant to this Section 3.5(c) and such interest and participation may be
recovered from such Bank together with interest thereon at the Federal Funds
Rate for each day during the period commencing on the date of demand by the
Administrative Agent and ending on the date such obligation is fully satisfied.

        3.6   Alternate Currency Syndicated Loans.

        (a)    Upon the satisfaction of the conditions precedent set forth in
Sections 8.1, 8.2 and 8.3 hereof and set forth in the applicable Alternate
Currency Addendum, from and including the later of the date of this Agreement
and the date of execution of the applicable Alternate Currency Addendum and
prior to the Termination Date (unless an earlier termination date shall be
specified in the applicable Alternate Currency Addendum), each applicable
Alternate Currency Bank agrees, on the terms and conditions set forth in this
Agreement and in the applicable Alternate Currency Addendum, to make Alternate
Currency Syndicated Loans under such Alternate Currency Addendum to the
applicable Borrower party to such Alternate Currency Addendum from time to time
in the applicable Alternate Currency, in an amount not to exceed each such
Alternate Currency Bank's applicable Alternate Currency Commitment; provided,
however, at no time shall the Dollar Equivalent of the outstanding principal
amount of the Alternate Currency Loans for all Alternate Currencies exceed
$200,000,000 other than as a result of currency fluctuations and then only to
the extent permitted in Section 4.2(h); provided, further, at no time shall the
Dollar Equivalent of the Alternate Currency Syndicated Loans for any specific
Alternate Currency exceed the maximum amount specified as the maximum amount
for such Alternate Currency in the applicable Alternate Currency Addendum other
than as a result of currency fluctuations and then only to the extent permitted
in Section 4.2(h).  Each Alternate Currency Syndicated Loan under this Section
3.6 shall consist of Alternate Currency Syndicated Loans made by each
applicable Alternate Currency Bank ratably in proportion to such Alternate
Currency Bank's respective Alternate Currency Share.  Subject to the terms of
this Agreement and the applicable Alternate Currency Addendum, the Borrowers
may borrow, repay and reborrow Alternate Currency Syndicated Loans at any time
prior to the Termination Date.  On the Termination Date, the outstanding
principal balance of the Alternate Currency Loans shall be paid in full by the
applicable Borrower and prior to the Termination Date prepayments of the
Alternate Currency Loans shall be made by the applicable Borrower if and to the
extent required in Section 4.2.

        (b)   MascoTech may, by written notice to the Administrative Agent
request the establishment of additional Alternate Currency Commitments in
additional Alternate Currencies other than Pounds Sterling, Deutsche Marks and
Italian Lire, provided the Dollar Equivalent of the aggregate amount of all of
the Alternate Currency Commitments does not exceed $200,000,000 ("Request for a
New Alternate Currency Facility").  The Administrative Agent will promptly
forward to the Banks any Request for a New Alternate Currency Facility received
from MascoTech; provided each Bank shall be deemed not to have agreed to such
request unless its written consent thereto has been received by the
Administrative Agent within ten (10) Business Days from the date of such
notification by the Administrative Agent to such Bank.  In the event that
sufficient Banks consent to such Request for a New Alternate Currency Facility,
upon execution of the applicable Alternate Currency Addendum and the other
documents, instruments and agreements required pursuant to this Agreement and
such Alternate Currency Addendum, the Alternate Currency Loans with respect
thereto may be made. 

        (c)   Except as otherwise required by applicable law, in no event shall
the Alternate Currency Agent or Alternate Currency Banks have the right to
accelerate the Alternate Currency Loans outstanding under any Alternate
Currency Addendum or to terminate their commitments (if any) 



                                       36

thereunder to make Alternate Currency Loans prior to the stated termination
date in respect thereof, except that such Alternate Currency Agent and
Alternate Currency Banks shall, in each case, have such rights upon an  
acceleration of the Loans and a termination of the Revolving Credit Commitments
pursuant to Article IX.

        (d)   Each Alternate Currency Agent shall furnish to the Administrative
Agent and the applicable Alternate Currency Banks, not less frequently than
monthly, and at any other time at the reasonable request of the Administrative
Agent, a statement setting forth the outstanding Alternate Currency Loans made
and repaid during the period since the last such report under such Alternate
Currency Addendum.

        (e)   Immediately and automatically upon the occurrence of an Event of
Default under Section 9.1(a), (f) or (g), each Bank shall be deemed to have
unconditionally and irrevocably purchased from each Alternate Currency Bank,
without recourse or warranty, an undivided interest in and participation in
each Alternate Currency Syndicated Loan ratably in accordance with such Bank's
Revolving Credit Commitment Percentage of the amount of such Loan, and
immediately and automatically all Alternate Currency Syndicated Loans shall be
converted to and redenominated in Dollars equal to the Dollar Equivalent of
each such Alternate Currency Loan determined as of the date of such conversion. 
Each of the Banks shall pay to the applicable Alternate Currency Bank not later
than two (2) Business Days following a request for payment from such Alternate
Currency Bank, in Dollars, an amount equal to the undivided interest in and
participation in the Alternate Currency Syndicated Loan purchased by such Bank
pursuant to this Section 3.6(e).  In the event that any Bank fails to make
payment to the applicable Alternate Currency Bank of any amount due under this
Section 3.6(e), the Administrative Agent shall be entitled to receive, retain
and apply against such obligation the principal and interest otherwise payable
to such Bank hereunder until the Administrative Agent receives from such Bank
an amount sufficient to discharge such Bank's payment obligation as prescribed
in this Section 3.6(e) together with interest thereon at the Federal Funds Rate
for each day during the period commencing on the date of demand by the
Administrative Agent and ending on the date such obligation is fully satisfied. 
The Administrative Agent will promptly remit all payments received as provided
above to the applicable Alternate Currency Bank.

        3.7   Notice to Banks; Funding of Loans.   

              (a)  Notice of Syndicated Borrowings.  The applicable Borrower 
shall give the Administrative Agent or the applicable Alternate Currency
Agent, as required, written notice in substantially the form attached hereto as
Exhibit C-1 (a "Notice of Syndicated Borrowing") signed by an Authorized
Officer or person designated by an Authorized Officer not later than 12:00 noon
(Detroit time) on the Business Day of each Borrowing of a Floating Rate
Revolving Loan, not later than 11:00 a.m. (Detroit time) on the third Business
Day before each Borrowing of a Eurodollar Rate Syndicated Loan, and not later
than 11:00 a.m. (Detroit time) on the fourth Business Day before each Borrowing
of an Alternate Currency Syndicated Loan, or as specified in the applicable
Alternate Currency Addendum, specifying:  (i) the date of such Borrowing, which
shall be a Business Day, (ii)


                                       37

<PAGE>   45

whether such Borrowing is pursuant to a Term Loan, a Revolving Credit
Syndicated Loan or an Alternate Currency Syndicated Loan, (iii) the
aggregate amount of such Borrowing and, in the case of each Alternate Currency
Syndicated Loan, the Dollar Equivalent of such Borrowing and the currency in
which such Borrowing is denominated, (iv) whether the Loans comprising such
Borrowing are to be, in the case of Term Loans or Revolving Loans, Floating
Rate Loans or Eurodollar Rate Syndicated Loans or Alternate Currency Syndicated
Loans and (v) in the case of each Eurodollar Rate Syndicated Borrowing or
Alternate Currency Syndicated Loan, the duration of the Interest Period
applicable thereto, which shall comply with the provisions of the definition of
the applicable Interest Period.

              (b)   Request for Letter of Credit Issuance; Notice of Bid-Option
Borrowing; Notice of Swing Line Borrowing.  The applicable Borrower shall give
the Administrative Agent or the applicable Alternate Currency Agent, as
required, written notice in conformity with the Section 3.3(b) in the case of a
Request for Letter of Credit Issuance, Section 3.4(f) in the case of a Notice of
Bid-Option Borrowing and Section 3.5(b) in the case of a Notice of Swing Line
Borrowing.

              (c)   Upon receipt of a Notice of Borrowing or Request for Letter 
of Credit Issuance, the Administrative Agent or the Alternate Currency Agent, as
applicable, shall promptly notify each applicable Bank of the contents thereof
and of such Bank's share, if any, of such Borrowing or the related Letter of
Credit risk, as the case may be.  A Notice of Borrowing or Request for Letter of
Credit Issuance shall be irrevocable by the applicable Borrower once the
Administrative Agent, or the applicable Alternate Currency Agent, begins
notifying any Bank of the contents thereof.

              (d)   Each Bank, not later than 1:00 p.m. (Detroit time) on the 
date any Borrowing is requested to be made, other than an Alternate Currency
Borrowing or a Borrowing of a Swing Line Loan, shall make its share, if any, of
such Borrowing available to the Administrative Agent in immediately available
funds, at the Administrative Agent's address specified in or pursuant to Section
11.2, for disbursement to the applicable Borrower.  Unless the Administrative
Agent determines that any applicable condition specified in Article VIII has not
been satisfied, the Administrative Agent will make funds actually so received
from the Banks available to the applicable Borrower at the Administrative
Agent's aforesaid address.  Unless the Administrative Agent shall have received
notice from any Bank prior to the date such Borrowing is requested to be made
that such Bank will not make available to the Administrative Agent such Bank's
share of such Borrowing, the Administrative Agent may assume that such Bank has
made such share available to the Administrative Agent on the date such Borrowing
is requested to be made in accordance with this Section 3.7.  If and to the
extent such Bank shall not have so made such share available to the
Administrative Agent, the Administrative Agent may (but shall not be obligated
to) make such amount available to the applicable Borrower, and such Bank and the
applicable Borrower severally agree to pay to the Administrative Agent forthwith
on demand such amount, together with interest thereon for each day from the date
such amount is made available to the applicable Borrower by the Administrative
Agent until the date such amount is repaid to the Administrative Agent at (i) in
the case of such Bank, the Federal Funds Rate and (ii) in the case of the
applicable Borrower, a rate per annum equal to the interest rate applicable to
such Borrowing during such period.  If such Bank shall pay such amount to the
Administrative Agent together with interest, such amount so paid shall
constitute a Loan by such Bank as a part of the related 

                                       38

<PAGE>   46

Borrowing for purposes of this Agreement.  The failure of any Bank to make its  
share of any Borrowing available to the Administrative Agent shall not relieve
any other Bank of its obligation to make available to the Administrative Agent
its share, if any, of such Borrowing on the date such Borrowing is requested to
be made, but no Bank shall be responsible for failure of any other Bank to make
such share available to the Administrative Agent on the date of such Borrowing.

              (e)(i)  Each Bank making an Alternate Currency Bid-Option Loan  
shall make its share, if any, of such Borrowing available to the
applicable Borrower not later than 11:00 a.m. (local time in the principal
financial center of the country issuing the Alternate Currency) on the date any
Alternate Currency Bid-Option Borrowing is requested to be made by depositing
the proceeds thereof in an account maintained and designated by the applicable
Borrower at an office or branch of such Bank (or of an Affiliate of such Bank)
located in the principal financial center of the country issuing the Alternate
Currency in which such Borrowing is denominated or, if neither such Bank nor
any Affiliate of such Bank has an office or branch in such financial center, at
such Bank's Eurodollar Lending Office or Domestic Lending Office as selected by
such Bank, or by such other means requested by the applicable Borrower and
acceptable to such Bank.  Promptly upon any such disbursement of an Alternate
Currency Bid-Option Loan, the Bank making such Loan shall give written notice
to the Administrative Agent by telex or telecopy of the making of such Loan,
which notice shall be substantially in the form attached hereto as Exhibit H.

              (ii)  Subject to the  procedures set forth in the applicable
Alternate Currency Addendum, each Alternate Currency Bank shall make available
its Alternate Currency Syndicated Loan or Loans, in funds immediately available
to the Alternate Currency Agent at its office designated in the Alternate
Currency Addendum for payments of such Alternate Currency in the Alternate
Currency.  The Alternate Currency Agent will promptly make the funds so received
from the Alternate Currency Banks available to the applicable Borrower. Promptly
upon any such disbursement of an Alternate Currency Syndicated Loan, the
Alternate Currency Agent, shall give written notice to the Administrative Agent
by telex or telecopy of the making of such Loan, which notice shall be
substantially in the form attached hereto as Exhibit H. 

             (iii)  If for any reason any applicable Alternate Currency Bank 
fails to make payment to the applicable Alternate Currency Agent of any amount 
due under Section 3.7(e)(ii) and the applicable Alternate Currency Addendum, the
applicable Alternate Currency Agent shall be entitled to receive, retain and
apply against such obligation the principal and interest otherwise payable to
such Alternate Currency Bank hereunder until the Alternate Currency Agent
receives such payment from such Alternate Currency Bank or such obligation is
otherwise fully satisfied.  In addition to the foregoing, if for any reason any
Alternate Currency Bank fails to make payment to the applicable Alternate
Currency Agent of any amount due under Section 3.7(e)(ii) and the applicable
Alternate Currency Addendum, such Alternate Currency Bank shall be deemed, at
the option of the applicable Alternate Currency Agent, to have unconditionally
and irrevocably purchased from the applicable Alternate Currency Agent, without
recourse or warranty, an undivided interest in and participation in the
applicable Alternate Currency Loan in the amount such Alternate Currency Bank
was required to pay pursuant to Section 3.7(e)(ii) and the applicable Alternate
Currency Addendum, and such interest 


                                       39

<PAGE>   47

and such participation may be recovered from such Alternate Currency Bank
together with interest thereon at the Federal Funds Rate for each day
during the period commencing on the date of demand by the applicable Alternate
Currency Agent and ending on the date such obligation is fully satisfied.

        3.8   The Notes.

              (a)   The Revolving Loans of each Bank shall be evidenced by a
Revolving Credit Note payable to the order of such Bank in an amount equal to
the Revolving Credit Commitment of such Bank.

              (b)   The Term Loans of each Bank shall be evidenced by a Term 
Loan Note payable to the order of such Bank in an amount equal to the
Term Loan Commitment of such Bank.

              (c)   The Bid-Option Loans of each Bank shall be evidenced by a
single Bid-Option Note payable to the order of such Bank in an amount equal to
the Dollar Equivalent of the aggregate unpaid principal amount of such Bank's
Bid-Option Loans.

              (d)   The Alternate Currency Syndicated Loans of each Alternate
Currency Bank shall be evidenced by a single Alternate Currency Syndicated Note
payable to the order of such Bank in an amount equal to the Alternate Currency
Commitment of such Bank.

              (e)   Upon receipt of each Bank's Notes pursuant to Section 8.2, 
the Administrative Agent shall forward such Notes to such Bank.  Each Bank shall
record on its books and records, and prior to any transfer of its Notes shall
endorse on the schedules forming a part thereof appropriate notations to
evidence, the date of disbursement, amount and maturity of each Loan made by it,
the interest rate and Interest Period applicable thereto and the date and amount
of each payment of principal made by the applicable Borrowers with respect
thereto.  Any notations made by such Bank shall be prima facie evidence of the
matters so recorded or endorsed.  Each Bank is hereby irrevocably authorized by
the Borrowers to make such records, so to endorse schedules to its Notes and to
attach to and make a part of any  Note a continuation of any such schedule as
and when required.  Failure by any Bank to make such records or so to endorse
the schedules to its Notes, or any error in recording or so endorsing any such
information, shall not affect the Borrowers' liability hereunder or under any
Note.

        3.9   Certain Fees.

              (a)   Facility Fee.  MascoTech will pay to the Administrative 
Agent for the respective accounts of the Banks a facility fee, for each
calendar quarter or portion thereof from the Closing Date to but not
including the Termination Date, on the amount of each Bank's Revolving Credit
Commitment and Term Loans, whether used or unused, during such period, at a rate
equal to the Applicable Facility Fee Rate.  All accrued facility fees
hereunder shall be payable in arrears with respect to each calendar quarter or
portion thereof not later than the tenth day after the end of each March, June,
September and December, commencing with the first such calendar quarter-end
after the 


                                       40

<PAGE>   48

Closing Date, and on the Termination Date.  Promptly upon receipt of such
facility fees for any calendar quarter or portion thereof, the Administrative
Agent shall distribute such facility fees to the Banks ratably in accordance
with their respective Pro Rata Shares.

              (b)   AgentS' and Arrangers' Fees and Closing Fee.  MascoTech will
pay to the Agents and to the Arrangers fees in such amounts and at such times as
are agreed to in the Agents and Arrangers Fee Letter and the Administrative
Agent Fee Letter, each dated as of December 10, 1997 and the Administrative
Agent shall distribute out of such fees, closing fees to the Banks on the
Closing Date.

        3.10  Optional Termination or Reduction of Commitments.

              Subject to Section 5.5, the Borrowers shall have the right at any
time and from time to time, upon one Business Day's prior written notice
to the Administrative Agent, to terminate or proportionately reduce the amount
of the Revolving Credit Commitments or the Alternate Currency Commitments,
provided, that (i) any partial reduction of the amount of the Revolving Credit
Commitments shall be in the amount of $5,000,000 or a multiple of $1,000,000 in
excess thereof and any partial reduction of any Alternative Currency Commitment
shall be in the Approximate Equivalent Amount of $1,000,000 or any integral
multiple thereof, (ii) no such reduction shall be permitted with respect to any
portion of the Revolving Credit Commitments not in excess of the sum of the
Dollar Equivalent of the aggregate outstanding principal amount of all
Revolving Loans, Bid-Option Loans plus Alternative Currency Syndicated Loans
and Swing Line Loans, plus the Letter of Credit Obligations Amount, plus the
Dollar Equivalent of the aggregate amount of all Borrowings for which a Notice
of Borrowing is then pending, plus the aggregate amount of all Letters of
Credit for which a Request for Letter of Credit Issuance is then pending, (iii)
the Commitments may not be terminated if any Loans or Letters of Credit are
then outstanding or any Notice of Borrowing or Request for Letter of Credit
Issuance is then pending and (iv) no such termination or reduction shall be
permitted if, after giving effect thereto, the Dollar Equivalent of the
aggregate principal amount of the outstanding Bid-Option Loans would exceed
fifty percent (50%) of the aggregate amount of the sum of the Revolving Credit
Commitments and the outstanding aggregate principal amount of the Term Loans. 
The Revolving Credit Commitments or any portion thereof terminated or reduced
pursuant to this Section may not be reinstated.  The accrued facility fees with
respect to the terminated Revolving Credit Commitments or the amount of any
reduction therein shall be payable on the effective date of such notice.  Upon
receipt of any notice from the Borrowers pursuant to this Section, the
Administrative Agent shall promptly notify each Bank of the contents thereof
and of such Bank's share of any reduction of the Commitments.  Each such notice
shall be irrevocable by the Borrowers once the Administrative Agent begins
notifying any Bank of the contents thereof.

        3.11  Mandatory Termination of Commitments.  The Revolving Credit
Commitments shall terminate on the Termination Date.  The Term Loan Commitments
shall terminate upon disbursement of the Term Loans on the Closing Date.

        3.12  Borrowing Subsidiaries.  MascoTech may at any time or from time
to time, with the consent of the Administrative Agent, which consent shall not
be unreasonably withheld, add as a party to this Agreement any Subsidiary to be
a "Borrowing Subsidiary" hereunder by the execution and delivery to the
Administrative Agent of a duly completed Assumption Letter by such Subsidiary,
with the written consent of MascoTech at the foot thereof.  Upon such
execution, delivery and consent, such Subsidiary shall for all purposes be a
party hereto as a Borrowing Subsidiary as fully as if it had executed and
delivered this Agreement.  So long as the principal of and interest on any
Loans made to any Borrowing Subsidiary under this Agreement shall have been
repaid or paid in full, all  Letters of Credit issued for the account of such
Borrowing Subsidiary have expired or been returned and terminated and all other
obligations  (other than contingent indemnification obligations) of such
Borrowing Subsidiary under this Agreement shall have been fully performed,
MascoTech may, by not less than five Business Days' prior notice to the
Administrative Agent (which shall promptly notify the Banks thereof), terminate
such Borrowing Subsidiary's status as a Borrowing Subsidiary.

Notwithstanding the foregoing, the final installment shall be in the amount of  
the then outstanding principal balance of the Term Loans.  In addition, the
then outstanding principal balance of the Term Loans, if any, shall be due and

reborrowed once repaid.

        4.2   Prepayments of Principal.  The following provisions apply in
respect of prepayment of the Loans, other than Swing Line Loans, by any
Borrower:

        (a)   The Borrowers may prepay Floating Rate Loans in whole or in part
on any Business Day in amounts aggregating $5,000,000 or multiples of
$1,000,000 in excess thereof (unless such prepayment would cause the aggregate
outstanding principal amount of Floating Rate Loans to be less than $5,000,000,
in which event prepayment may only be made in an amount equal to the entire
outstanding principal amount of Floating Rate Loans), by paying the principal
amount being prepaid together with accrued interest thereon to the date of
prepayment.  Each prepayment in part of such Loans shall be applied to such
Loans of the Banks ratably in accordance with their respective shares of the
aggregate outstanding principal amount of the Floating Rate Loans.

        (b)   The Borrowers may, upon at least three Business Days' notice to
the Administrative Agent, prepay any Eurodollar Rate Syndicated  Loan in whole
or in part on any Business Day in the amount of $5,000,000 or the Approximate
Equivalent Amount of $1,000,000 of any Alternate Currency Syndicated Loan or
multiples of $1,000,000 or the Approximate Equivalent Amount of $1,000,000 of
any Alternate Currency in excess thereof (unless, in the case of prepayment of
any Eurodollar Rate Syndicated Loan, such prepayment would cause the aggregate
outstanding principal amount of such Eurodollar Rate Syndicated  Loan to be
less than $5,000,000, in which event prepayment may only be made in an amount
equal to the outstanding unpaid principal amount of such Eurodollar Rate
Syndicated  Loan), by paying the principal amount being prepaid together with
accrued interest thereon to the date of prepayment; provided, however, that the
Borrowers shall 



                                       43

<PAGE>   51

compensate the Banks pursuant to Section 5.5 for any losses or expenses
incurred as a result thereof.  Each prepayment in part of any Eurodollar Rate
Syndicated  Loan shall be applied to the Eurodollar Rate Syndicated  Loans      
comprising such Borrowing of the Banks ratably in accordance with their
respective shares of the aggregate outstanding principal amount of such Loans.

        (c)   Unless otherwise required by this Agreement, the Borrowers may
not prepay any Bid-Option Loan in whole or in part without the consent of the
Bank that made such Bid-Option Loan.

        (d)   Notwithstanding Section 4.2(a), (b) and (c), if on any date:

                      (i)   the sum of (A) the Dollar Equivalent of
                the aggregate outstanding principal amount of Loans plus (B)
                the Letter of Credit Obligations Amount exceeds the sum of
                the aggregate amount of the Revolving Credit Commitments and
                the outstanding aggregate principal amount of the Term Loans;
                or


                      (ii)  the Dollar Equivalent of the aggregate outstanding
                principal amount of Bid-Option Loans exceeds fifty percent
                (50%) of the sum of the Revolving Credit Commitments and the
                aggregate outstanding principal amount of the Term Loans; or

                      (iii) the Dollar Equivalent of the aggregate outstanding
                principal amount of Alternate Currency Bid-Option Loans and the
                Alternate Currency Syndicated Loans exceeds $200,000,000,

then the Borrowers shall pay forthwith the principal amount of such excess,     
together with accrued interest thereon to the date of payment; provided,
however, that the Borrowers shall compensate the Banks pursuant to Section 5.5
for any losses or expenses incurred as a result thereof; and provided further,
however, that (A) no such payment otherwise required under clause (i) of this
Section 4.2(d) solely because of currency exchange rate fluctuations affecting
the Dollar Equivalent of the aggregate outstanding principal amount of
Alternate Currency Syndicated Loans or Alternate Currency Bid-Option Loans
shall be required unless such payment is due on a date when a payment of
principal of any Loan is otherwise due hereunder, and (B) notwithstanding
clause (A) of this proviso, no such payment otherwise required under subsection
(ii) or (iii) of this Section 4.2(d) shall be required if due solely because of
currency exchange rate fluctuations affecting the Dollar Equivalent of the
aggregate outstanding principal amount of Alternate Currency Syndicated Loans
and Alternate Currency Bid-Option Loans since the last date on which any of
such Alternate Currency Syndicated Loans  or Alternate Currency Bid-Option
Loans, as the case may be, were made.  

        (e)   Upon receipt of a notice of prepayment pursuant to this Section,
the Administrative Agent shall promptly notify each Bank of the contents
thereof and of such Bank's share (in accordance with Section 4.4) of such
prepayment. Each such notice shall be irrevocable by the Borrowers once the
Administrative Agent begins notifying any Bank of the contents thereof.


                                       44

        (f)   At any time that the most recently determined Senior Debt
Coverage Ratio is greater than 3.0 to 1.0 (after giving pro forma effect to the
application of proceeds prescribed herein below), upon the consummation of any
Asset Sale or any Financing by MascoTech or any of its Consolidated
Subsidiaries (other than (i) sales of inventory in the ordinary course of
business and (ii) sales or other dispositions of equipment which in the
reasonable judgment of MascoTech is no longer used or useful in the business of
MascoTech) except to the extent that the Net Cash Proceeds of such Asset Sale,
when combined with the Net Cash Proceeds of all such Asset Sales during the
immediately preceding twelve-month period, do not exceed $25,000,000, and
except as provided in the immediately succeeding sentence, within three (3)
Business Days after MascoTech's or any of its Subsidiaries' receipt of any Net
Cash Proceeds from any such Asset Sale or Financing, the Borrowers shall make a
mandatory prepayment in an amount equal to one hundred percent (100%) of such
Net Cash Proceeds or such lesser amount as is sufficient to reduce the Senior
Debt Coverage Ratio (calculated using EBITDA for the most recently concluded
four fiscal quarter period and using Debt as of the last day of such four
fiscal quarter period, taking into account the reduction in such Debt as a
result of such mandatory prepayment on a pro forma basis) to 3.0 to 1.0.  Net
Cash Proceeds of Asset Sales of capital assets with respect to which the
Borrowers shall have given the Agent written notice of its intention to replace
such capital assets within six months following such Asset Sale shall not be
subject to the provisions of the preceding sentence unless and to the extent
that such applicable period shall have expired without such replacement having
been made.  Each such mandatory prepayment shall be applied first to the Term
Loan installment due January 31, 2002 and after such installment is paid in
full to each of the then remaining installments payable under the Term Loans in
the inverse order of maturity; and following the payment in full of the Term
Loans, the amount of each such prepayment shall be applied to repay Revolving
Loans (but shall reduce Revolving Loan Commitments only at the option of the
Borrowers).  Subject to the preceding provisions of this Section 4.2(f), all of
the mandatory prepayments made pursuant to this Section 4.2(f) shall be applied
first to Floating Rate Loans and to any Eurodollar Rate Loans maturing on such
date.  The Administrative Agent shall hold the remaining portion of such
mandatory prepayment as cash collateral in an interest bearing deposit account
and shall apply funds from such account to Eurodollar Rate Loans at the end of
the applicable Interest Period.

        (g)   All voluntary prepayments of the Term Loans shall be applied, at
the Borrowers' option, either to the installment due January 31, 2002 or to the
other remaining installments of the Term Loans, pro rata, or any combination of
the foregoing.

        (h)   If on the last Business Day of any month, the Dollar Equivalent
of all outstanding Alternate Currency Syndicated Loans under the Alternate
Currency Addenda exceeds 105% of the aggregate Alternate Currency Commitments
with respect thereto, the applicable Borrowers shall on such date prepay
Alternate Currency Syndicated Loans in an aggregate amount such that after
giving effect thereto the Dollar Equivalent of all such Alternate Currency
Syndicated Loans is less than or equal to the aggregate Alternate Currency
Commitments with respect thereto.

        4.3   Interest Payments.  The Borrowers shall pay interest to the Banks
on the unpaid principal amount of each Loan, for the period commencing on the
date such Loan is made until such 







                                       45




<PAGE>   53

Loan is paid in full, on each Interest Payment Date and at maturity
(whether at stated maturity, by acceleration or otherwise), and thereafter on
demand, at the following rates per annum (subject, however, to the provisions   
of Section 11.12):

        (a)   With respect to each Floating Rate Loan, at the Floating Rate.

        (b)   With respect to each Loan which bears interest at the Eurodollar
Rate, the Eurodollar Rate, provided that if any Eurodollar Rate Syndicated
Revolving Loan or any portion thereof shall, as a result of clause (c) of the
definition of Eurodollar Rate Interest Period, have an Interest Period of less
than one month, such Loan or portion thereof shall bear interest during such
Interest Period at the Floating Rate.  

        (c)   With respect to each Eurodollar Rate Bid-Option Loan, the
Bid-Option Eurodollar Rate, provided that if any Eurodollar Rate Bid-Option
Loan or any portion thereof shall, as a result of clause (c) of the definition
of Eurodollar Rate Interest Period, have an Interest Period of less than one
month, in the case of a Eurodollar Rate Syndicated Loan, or fifteen days, in
the case of a Eurodollar Rate Bid-Option Loan, such Loan or portion thereof
shall bear interest during such Interest Period at the Floating Rate.

        (d)   With respect to each Absolute Rate Dollar Bid-Option Loan and
Alternate Currency Bid-Option Loan, the Bid-Option Absolute Rate quoted for
such Loan by the Bank making such Loan.

        (e)   With respect to each Alternate Currency Syndicated Loan, the rate
prescribed in the applicable Alternate Currency Addendum.

        (f)   Notwithstanding the foregoing subsections (a) through (e), the
Borrowers shall (subject to the provisions of Section 11.12), at the option of
the Required Banks, pay interest on demand at the Overdue Rate on the
outstanding principal amount of all Loans and any other amount payable by the
Borrowers hereunder after the occurrence and during the continuance of an Event
of Default under Section 9.1(a), (b), (d), (e), (f), (g) or (k).

        4.4   Payment Procedures.

              (a)   All payments of any facility fees, closing fees, Letter of
Credit fees, Agent's fees, or other fees hereunder and of principal of, and
interest on, the Loans, other than Alternate Currency Loans, and of
reimbursement obligations in respect of Letters of Credit shall be made in
Dollars and in funds immediately available at the Administrative Agent's
principal office in Detroit, Michigan not later than 1:00 p.m. (Detroit time) on
the date on which such payment shall become due.  All payments of principal of,
and interest on, the Alternate Currency Loans shall be made in the currencies in
which such Loans are denominated and in funds immediately available, freely
transferable and cleared at the office or branch from which the Loan was made
under Section 3.4(a)  and 3.6 not later than 3:00 p.m. local time on the date on
which such payment shall become due.  Promptly upon receipt of any payment of
principal of the Alternate Currency Loans the Bank receiving 

                                       46
<PAGE>   54

such payment shall give written notice to the Administrative Agent by telex or
telecopy of the receipt of such payment, which notice shall be  substantially
in the form attached hereto as Exhibit I.  Whenever any payment of principal
of, or interest on, the Loans or of any fee shall be due on a day which is not
a Business Day, the date for payment thereof shall be extended to the next
succeeding Business Day (unless as a result thereof, in respect of Eurodollar
Rate Loans and Alternate Currency Syndicated Loans, such date would fall in the
next calendar month, in which case it shall be advanced to the next preceding
Business Day) and, in the case of a payment of principal, interest thereon
shall be payable for any such extended time.

              (b)   Payments of principal of Syndicated Loans that comprise a
Syndicated Borrowing, including any Substitute Loan made by a Bank as part of
any Borrowing of a Eurodollar Rate Syndicated  Revolving Loan, shall be promptly
distributed by the Administrative Agent to the Banks that made such Syndicated
Loans ratably in proportion to their respective shares of the outstanding
principal amount of such Syndicated Borrowing.  Payments of interest on
Syndicated Loans that comprise a Syndicated Borrowing, including any Substitute
Loan made by a Bank as part of any Borrowing of a Eurodollar Rate Syndicated
Revolving Loan, shall be promptly distributed by the Administrative Agent to the
Banks that made such Syndicated Loans so that each such Bank receives a portion
of such payment equal to the amount of interest then owing to such Bank on such
Loans multiplied by a fraction, the denominator of which is the total amount of
interest then owing to all such Banks on such Loans and the numerator of which
is the amount of such payment.  Payments of principal of any Dollar Bid-Option
Loans that comprise a Dollar Bid-Option Borrowing shall be promptly distributed
by the Administrative Agent to the Banks that made such Dollar Bid-Option Loans
ratably in accordance with their respective Dollar Bid-Option Percentages
together with interest ratably in accordance with the respective interest rates
applicable to such Loans.

              (c)   During any period when Dollar Bid-Option Loans are
outstanding, if the Administrative Agent cannot reasonably determine
whether a particular payment received by the Administrative Agent from the
applicable Borrower was intended to be applied to the principal of or interest
on one or more Dollar Bid-Option Borrowings or to the principal of or interest
on Syndicated Borrowings, or if the amount of any payment by the Borrowers is
insufficient to pay all amounts then due and payable with respect to Dollar
Bid-Option Loans and Syndicated Loans (including Substitute Loans), the
Administrative Agent shall first apportion such payment between the Dollar Bid-
Option Loans and the Syndicated Loans (including Substitute Loans) (i) if such
payment is of principal, ratably in accordance with the aggregate principal
amount of each such type of Loans on which payment is then due, and (ii) if
such payment is of interest, ratably in accordance with the aggregate amount of
interest that is then due on each such type of Loans.  After such
apportionment, (i) the Administrative Agent shall distribute the portion of the
payment received and allocated to the Syndicated Loans (including Substitute
Loans) to the Banks as provided for payments of principal of or interest on, as
the case may be, Syndicated Loans under Section 4.4(b), and (ii) the portion of
the payment received and allocated to the Dollar Bid-Option Loans on which a
payment is then due shall first be allocated among the different Dollar
Bid-Option Borrowings of which such Dollar Bid-Option Loans are a part (A) if
such payment is of principal, ratably in accordance with the aggregate
principal amount of each such Dollar Bid-Option Borrowing, and (B) if such
payment is of interest, ratably in accordance with the 

                                       47

<PAGE>   55

aggregate amount of interest that is then due on each such Dollar Bid-Option
Borrowing.  After such allocation, the Administrative Agent shall       
distribute the amount allocated to each Dollar Bid-Option Borrowing to the
Banks that made the Dollar Bid-Option Loans comprising such Dollar Bid-Option
Borrowing ratably in accordance with their respective Dollar Bid-Option
Percentages.

              (d)   Any prepayments of Bid-Option Loans made under Section 
4.2(d) may be applied to any one or more Bid-Option Borrowings as the
Borrowers may select; provided that such payments of principal shall be applied
by the Administrative Agent, in the case of Dollar Bid-Option Loans, or
made directly by the Borrowers, in the case of Alternate Currency Bid-Option
Loans, to the Banks participating in any such Bid-Option Borrowing ratably in
accordance with their respective Dollar Bid-Option Percentages or Alternate
Currency Bid-Option Percentages, as the case may be together with interest 
ratably in accordance with the respective interest rates applicable to such 
Loans.

        4.5   Computation of Interest and Fees.  Except as may be otherwise
prescribed in the applicable Alternate Currency Addendum, facility fees,
Administrative Agent fees and Letter of Credit fees, and interest on the
Floating Rate Loans and Alternate Currency Syndicated Loans and other amounts
due hereunder, other than Fixed Rate Loans (other than Alternate Currency
Syndicated Loans), shall be computed on the basis of a year of 365 or 366 days,
as the case may be, and actual days elapsed.  Interest on the Fixed Rate Loans
shall be computed on the basis of a year of 360 days and actual days elapsed.

        4.6   No Setoff or Deduction.  All payments of principal of and
interest on the Loans and other amounts payable by the Borrowers hereunder
shall be made by the Borrowers without setoff or counterclaim, and free and
clear of, and without deduction or withholding for, or on account of, any
present or future taxes, levies, imposts, duties, fees, assessments, or other
charges of whatever nature, imposed by any governmental authority, or by any
department, agency or other political subdivision or taxing authority.

        4.7   Types for all Loans.  The Syndicated Loans (other than Alternate
Currency Syndicated Loans) may be Floating Rate Loans or Eurodollar Rate Loans,
or a combination thereof, selected by the applicable Borrower in accordance
with Section 4.8.  The Term Loans and Revolving Loans made on the Closing Date
shall initially be Floating Rate Loans and thereafter may be continued as
Floating Rate Loans or converted into Eurodollar Rate Loans as provided in
Section 4.8.  The applicable Borrower may select, in accordance with Section
4.8, Types and Interest Periods applicable to portions of the Revolving Loans
and the Term Loans.  Notwithstanding anything herein to the contrary, the
Borrower may not, without the written consent of the Administrative Agent,
select the Eurodollar Rate with Interest Periods other than seven (7) or
fourteen (14) days for any Loans during the Syndication Period.  


                                       48
<PAGE>   56

        4.8   Method of Selecting Types and Interest Periods for Conversion and
Continuation of Loans.

        (A)  Right to Convert.  The Borrowers may elect from time to time,
subject to the provisions of Section 4.7 and this Section 4.8, to convert all
or any part of a Loan (other than a Swing Line Loan, an Alternate Currency
Syndicated Loan or a Bid-Option Loan) of any Type into any other Type or Types
of Loans; provided that any conversion of any Eurodollar Rate Syndicated Loan
shall be made on, and only on, the last day of the Interest Period applicable
thereto, unless the applicable Borrower makes the payments required pursuant to
Section 5.5.

        (B)  Automatic Conversion and Continuation.  Floating Rate Loans shall
continue as Floating Rate Loans unless and until such Floating Rate Loans are
converted into Eurodollar Rate Syndicated Loans.  Eurodollar Rate Syndicated
Loans shall continue as Eurodollar Rate Syndicated Loans until the end of the
then applicable Interest Period therefor, at which time such Eurodollar Rate
Syndicated Loans shall be automatically converted into Floating Rate Loans
unless the Borrower shall have given the Administrative Agent notice requesting
that, at the end of such Interest Period, such Eurodollar Rate Syndicated Loans
continue as a Eurodollar Rate Syndicated Loan. 

        (C)  No Conversion After Default.  Notwithstanding anything to the
contrary contained in Section 4.8(A) or Section 4.8(B), no Loan may be
converted into or continued as a Eurodollar Rate Syndicated Loan if the
Required Banks so direct after any Default or Event of Default has occurred and
is continuing.

        (D)  Conversion/Continuation Notice.  The Borrowers shall give the
Administrative Agent irrevocable notice (a "Conversion/Continuation Notice"),
in substantially the form attached hereto as Exhibit T or Exhibit C-1, as
applicable, of each conversion of a Floating Rate Loan into a Eurodollar Rate
Syndicated Loan or continuation of a Eurodollar Rate Syndicated Loan not later
than 11:00 a.m. (Detroit time) three Business Days prior to the date of the
requested conversion or continuation, specifying:  (1) the requested date
(which shall be a Business Day) of such conversion or continuation; (2) the
amount and Type of the Loan to be converted or continued; and (3) the amounts
of Eurodollar Rate Syndicated Loan(s) into which such Loan is to be converted
or continued and the duration of the Interest Periods applicable thereto. 

        4.9   Other Provisions Applicable to Alternate Currency Loans.  The
specification of payment of Alternate Currency Loans in the related Alternate
Currency at a specific place pursuant to this Agreement is of the essence. 
Such Alternate Currency shall be the currency of account and payment of such
Loans under this Agreement and the Notes.  Notwithstanding anything in this
Agreement, the obligation of the applicable Borrower in respect of such Loans
shall not be discharged by an amount paid in any other currency or at another
place, whether pursuant to a judgment or otherwise, to the extent the amount so
paid, on prompt conversion into the applicable Alternate Currency and transfer
to such Bank under normal banking procedure, does not yield the amount of such
Alternate Currency due under this Agreement and the Notes.  In the event that
any payment, whether pursuant to a judgment or otherwise, upon conversion and
transfer, does not result in payment  

                                     49
<PAGE>   57

of the amount of such Alternate Currency due under this Agreement and the
Notes, such Bank shall have an independent cause of action against the
Borrowers for the currency deficit.


                                  ARTICLE V.

                            CHANGE IN CIRCUMSTANCES

        5.1   Impossibility; Interest Rate Inadequate or Unfair.  (a) If before
the beginning of any Eurodollar Rate Interest Period:

              (i)   the Administrative Agent is advised by any Reference Bank 
              that deposits in Dollars (in the applicable amounts) are not
              being offered to such Reference Bank in the relevant market for
              such Eurodollar Rate Interest Period, or

              (ii)  the Required Banks advise the Administrative Agent that the 
              Eurodollar Base Rate will not adequately and fairly reflect the
              cost to such Banks of maintaining, making or funding, for such
              Eurodollar Rate Interest Period, Eurodollar Rate Syndicated Loans
              to which such Eurodollar Rate Interest Period applies,

the Administrative Agent shall forthwith give notice thereof to the Borrowers
and the Banks, whereupon until the Administrative Agent notifies        the
Borrowers that the circumstances giving rise to such suspension no longer
exist, the obligations, if any, of the Banks to make Eurodollar Rate Loans, as
the case may be, shall be suspended.  In the case of Eurodollar Rate Loans,
unless the Borrowers notify the Administrative Agent not later than 3:00 p.m.
(Detroit time) on the Business Day before the beginning of such Eurodollar Rate
Interest Period that the Borrowers elect not to borrow on such date, such
Borrowing shall, subject to the provisions of Section 8.1, be a Floating Rate
Borrowing.  Promptly after the Administrative Agent receives any such notice
from the Borrowers under this Section 5.1(a), the Administrative Agent shall
notify each Bank of the contents thereof.  Any such notice from the Borrowers
shall be irrevocable once the Administrative Agent begins notifying any Bank of
the contents thereof. 

              (b)   If deposits in Dollars (in the applicable amounts) are not
being offered to a Reference Bank in the relevant market for any Eurodollar Rate
Interest Period, by reason of circumstances affecting such Reference Bank and
not affecting the London or Nassau Interbank Market, generally, the
Administrative Agent shall, in consultation with the Borrowers and with the
consent of the Required Banks, appoint another Bank to act as a Reference Bank
hereunder.

        5.2   Illegality.  If, after the date of this Agreement, the
introduction of, or any change in, any applicable law, rule or regulation or in
the interpretation or administration thereof by any governmental authority
charged with the interpretation or administration thereof or compliance by any 

                                       50
<PAGE>   58

Bank (or its Applicable Lending Office) with any request or directive (whether
or not having the force of law) of any such authority shall make        it
unlawful or impossible for such Bank (or its Applicable Lending Office) to
honor its binding legal obligations, if any, hereunder to make, maintain or
fund any type of Fixed Rate Loans, such Bank shall so notify the Administrative
Agent, and the Administrative Agent shall forthwith give notice thereof to the
Borrowers, whereupon until such Bank notifies the Administrative Agent that the
circumstances giving rise to such suspension no longer exist, the obligation,
if any, of such Bank to make such type of Fixed Rate Loans shall be suspended. 
Before any Bank gives any notice of unlawfulness or impossibility to the
Administrative Agent under this Section 5.2, such Bank shall designate a
different Applicable Lending Office if such designation will avoid the need for
giving such notice and will not, in the judgment of such Bank, be otherwise
disadvantageous to such Bank.  Upon receipt of such notice, the applicable
Borrowers shall prepay in full the then outstanding principal amount of each
affected Fixed Rate Loan of such Bank together with accrued interest thereon
(a) on the last day of the then current Interest Period applicable to such Loan
if such Bank may lawfully continue to maintain and fund such Loan to such day,
or (b) immediately if such Bank may not lawfully continue to fund and maintain
such Loan to such day.  Concurrently with prepaying each such Fixed Rate Loan,
the applicable Borrowers shall borrow a Floating Rate Loan (or, if the
applicable Borrowers so elect by at least three Business Days' notice to the
Administrative Agent and such Bank, a Eurodollar Rate Syndicated Loan of an
unaffected type) in an equal principal amount from such Bank, for an Interest
Period coinciding with the remaining term of the Interest Period applicable to
such Fixed Rate Loan, and such Bank shall make such a Loan, provided that there
has been no acceleration of the amounts due under the Notes pursuant to Article
IX.

        5.3   Increased Cost; Yield Protection.

              (a)   If, after the date hereof, the introduction of, or any 
change in, any applicable law, treaty, rule or regulation (whether domestic 
or foreign and including, without limitation, the Federal Deposit
Insurance Act, as amended, and Regulation D of the Board of Governors of the
Federal Reserve System) or in the interpretation or administration thereof by
any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Bank (or its
Applicable Lending Office) with any request or directive of any such authority,
central bank or comparable agency (whether or not having the force of law),
 
              (i) shall subject any Bank (or its Applicable Lending Office) to
              any tax, duty or other charge with respect to its obligation to
              make any Loans, its Notes, any of its Loans or any of the
              Letters of Credit or shall change the basis of taxation of
              payments to any Bank (or its Applicable Lending Office) of the
              principal of or interest on any of its Fixed Rate Loans or in
              respect of its obligation, if any, to make any Loans or to
              participate in the risk of Letters of Credit (except for changes
              in the rate of tax on the overall net income of such Bank or its
              Applicable Lending Office imposed by the jurisdiction in which
              such Bank's principal executive office or Applicable Lending
              Office is located), or

                                       51
<PAGE>   59

              (ii)  shall impose, modify or deem applicable any reserve 
              (including, without limitation, any imposed by the Board of
              Governors of the Federal Reserve System, but excluding with
              respect to any Eurodollar Rate Syndicated Loan any reserve
              requirements to the extent included in clause (b) of the
              definition of Eurodollar Base Rate when calculating the
              Eurodollar Base Rate with respect to such Eurodollar Rate
              Syndicated Loan), special deposit or similar requirement
              (including, without limitation, any deposit insurance assessment
              in respect of deposits held outside the United States, against
              assets of, deposits with or for the account of, or credit
              extended by, any Bank's Applicable Lending Office, or shall
              impose on any Bank (or its Applicable Lending Office or the
              relevant interbank market or the United States certificate of
              deposit market) any other condition affecting its obligation, if
              any, to make Loans or to participate in the risk of Letters of
              Credit or affecting its Loans or the Letters of Credit or
              affecting the Borrowers' obligations under the Notes in respect
              of such Loans,


and the result of any of the foregoing is to increase the cost to such Bank (or 
its Applicable Lending Office) of making or maintaining its existing or future
Fixed Rate Loans or of participating in the risk of Letters of Credit, or to
reduce the amount of any sum received or receivable by such Bank (or its
Applicable Lending Office) under this Agreement or under the Notes (in respect
of Fixed Rate Loans or Letters of Credit) by an amount deemed by such Bank to
be material, then such Bank may notify the Borrowers (with a copy of any such
notice to be provided to the Administrative Agent) of any such fact of which it
has knowledge and demand compensation therefor; provided that, if such Bank
fails to demand such compensation (or notify the Borrowers that it will or may
demand such compensation) promptly upon becoming aware of the facts entitling
it to do so or, if such Bank is contesting the cause of such increased cost or
reduced sum received or receivable, promptly after the earlier of (A) the final
determination of such contest or (B) an officer of such Bank who is responsible
for the administration of the credit outstanding under this Agreement from such
Bank to the Borrowers becoming aware of such facts, such Bank shall not be
entitled to such compensation for the period before the date on which it
actually demands (or notifies the Borrowers that it will or may demand) such
compensation; provided, further, that if such Bank is contesting the cause of
such increased cost or reduced sum received or receivable, such Bank shall not
in any event be entitled to such compensation for any period prior to six
months before it notifies the Borrowers that such Bank may or will demand such
compensation.  The Borrowers agree to pay to such Bank such additional amount
or amounts as will compensate such Bank for such increased cost or reduction
within 15 days after demand by such Bank.  A certificate of such Bank setting
forth the basis for determining such additional amount or amounts necessary to
compensate such Bank shall be conclusive in the absence of manifest error. 
Each such Bank will designate a different Applicable Lending Office if such
designation would avoid the need for, or reduce the amount of such compensation
and would not, in the judgment of such Bank, be otherwise disadvantageous to
such Bank.  In the event that any Borrower is required to compensate any Bank
for any increased cost to such Bank pursuant to this Section 5.3(a), such
Borrower shall have the right, upon at least five Business Days' prior notice
to such Bank through the Administrative Agent, 

                                       52
<PAGE>   60

to prepay in full any outstanding Fixed Rate Loans that are related to such
increased cost of such Bank, together with accrued interest thereon to the
date of prepayment; provided that prepayment of such Fixed Rate Loans shall not
relieve such Borrower of its obligation to compensate such Bank in accordance
with this Section 5.3(a), the amount of which compensation shall be due at the
time of such prepayment, notwithstanding any other provision of this Section
5.3(a).  Concurrently with prepaying each such Fixed Rate Loan of such Bank,
such Borrower shall borrow a Floating Rate Loan (or, if such Borrower shall so
elect in its notice of prepayment, a Fixed Rate Loan of another Type) in an
equal principal amount from such Bank for an Interest Period coinciding with
the remaining term of the Interest Period applicable to such Fixed Rate Loan,
and such Bank shall make such a Floating Rate Loan (or Fixed Rate Loan of the
other Type), provided that there has been no acceleration of the amount due
under the Notes pursuant to Article IX.  The Borrowers shall pay compensation
owing to any Bank(s) under this Section 5.3(a) notwithstanding any subsequent
replacement (pursuant to Section 11.13) of the Bank(s) making demand for such
compensation.

              (b)   In the event that any applicable law, treaty, rule or
regulation (whether domestic or foreign) now or hereafter in effect and
whether or not presently applicable to any Bank or Administrative Agent, or any
interpretation or administration thereof by any governmental authority charged
with the interpretation or administration thereof, or compliance by any Bank or
Administrative Agent with any guideline, request or directive of any such
authority (whether or not having the force of law), including any risk-based
capital guidelines, affects or would affect the amount of capital required or
expected to be maintained by such Bank or the Administrative Agent (or any
corporation controlling such Bank or the Administrative Agent) and such Bank or
the Administrative Agent, as the case may be, determines that the amount of
such capital is increased by or based upon the existence of such Bank's or
Agent's obligations or Loans hereunder and such increase has the effect of
reducing the rate of return on such Bank's or Agent's (or such controlling
corporation's) capital as a consequence of such obligations or Loans hereunder
to a level below that which such Bank or the Administrative Agent (or such
controlling corporation) could have achieved but for such circumstances (taking
into consideration its policies with respect to capital adequacy) by an amount
deemed by such Bank or the Administrative Agent to be material, then such Bank
or the Administrative Agent may notify the Borrowers of any such fact of which
it has knowledge and the Borrowers shall pay to such Bank or the 
Administrative Agent, as the case may be, from time to time, upon request by
such Bank (with a copy of such request to be provided to the Administrative
Agent) or the Administrative Agent, additional amounts sufficient to compensate
such Bank or Administrative Agent (or such controlling corporation) for any
increase in the amount of capital and reduced rate of return which such Bank or
the Administrative Agent reasonably determines to be allocable to the existence
of such Bank's or Agent's obligations or Loans hereunder; provided that, if
such Bank or the Administrative Agent fails to notify the Borrowers of any such
fact promptly upon becoming aware thereof or, if such Bank or the
Administrative Agent is contesting the cause of such increase in the amount of
capital or reduced rate of return, promptly after the earlier of (A) the final
determination of such contest or (B) an officer of such Bank who is responsible
for the administration of the credit outstanding under this Agreement from such
Bank to the Borrowers becoming aware of any such fact, such Bank or the
Administrative Agent, as the case may be, shall not be entitled to such
compensation for the period before the date on which it actually notifies the
Borrowers of such fact; provided, further, that if such Bank or the 

                                       53
<PAGE>   61

Administrative Agent is contesting the cause of such increase in the amount of
capital or reduced rate of return, such Bank or the Administrative Agent,
as the case may be, shall not in any event be entitled to such compensation for
any period prior to six months before it notifies the Borrowers that such Bank
or the Administrative Agent, as the case may be, may or will demand such
compensation.  A statement as to the amount of such compensation, prepared in
good faith and in reasonable detail by such Bank or the Administrative Agent,
as the case may be, and submitted by such Bank or Administrative Agent to the
Borrowers, shall be conclusive in the absence of manifest error in computation. 
The Borrowers shall pay such compensation for the periods covered by such
notice notwithstanding any replacement (pursuant to Section 11.13) of the
Bank(s) making demand for such compensation.  

        5.4   Substitute Loans.  If (a) the obligation, if any, of any Bank to
make any type of Fixed Rate Loans has been suspended pursuant to Section 5.2 or
(b) any Bank has demanded compensation under Section 5.3(a) and the Borrowers
shall, by at least five Business Days' prior notice to such Bank through the
Administrative Agent, have elected that the provisions of this Section 5.4
shall apply to such Bank, then, unless and until such Bank notifies the
Borrowers that the circumstances giving rise to such suspension or demand for
compensation no longer apply:

              (i)   all Loans which would otherwise be made by such Bank as the
affected type of Fixed Rate Loans shall be made instead as Floating Rate Loans,
for an Interest Period coincident with the related Fixed Rate Borrowing, and
 
             (ii)   after each of its affected Fixed Rate Loans has been repaid,
all payments of principal which would otherwise be applied to repay such Fixed
Rate Loans shall be applied to repay its Substitute Loans instead.

        5.5   Funding Losses.  If any Borrower makes any payment of principal
with respect to any Fixed Rate Loan on any other date than the last day of an
Interest Period applicable thereto (whether pursuant to Section 3.10, 4.2
(other than 4.2(f)), 5.1, 5.2, 5.3 or 5.4, Article IX or otherwise), or if the
applicable Borrower fails to borrow any Fixed Rate Loan after the related
Notice of Borrowing has been given to the Administrative Agent, or if the
applicable Borrower fails to make any payment of principal or interest in
respect of a Fixed Rate Loan when due, the applicable Borrower shall reimburse
each Bank on demand for any resulting loss or expense incurred by such Bank,
including without limitation any loss incurred in obtaining, liquidating or
employing deposits from third parties, whether or not such Bank shall have
funded or committed to fund such Loan.  A statement as to the amount of such
loss or expense, prepared in good faith and in reasonable detail by such Bank
and submitted by such Bank to the applicable Borrower, shall be conclusive and
binding for all purposes absent manifest error in computation.  Calculation of
all amounts payable to each Bank under this Section 5.5 shall be made as though
such Bank shall have actually funded or committed to fund the relevant Fixed
Rate Loan through the purchase of an underlying deposit in an amount equal to
the amount of such Loan and having a maturity comparable to the related
Interest Period; provided, however, that such Bank may fund any Fixed Rate Loan
in any manner it sees fit and the foregoing assumption shall be utilized only
for the purpose of calculation of amounts payable under this Section 5.5.  In
connection with any  

                                     54
<PAGE>   62

assignment by any Bank of any portion of the Loans made pursuant to Section
11.6 and made during the Syndication Period, and if, notwithstanding the
provisions of Section 4.7, the Borrowers have requested and the Administrative
Agent has consented to the use of the Eurodollar Rate with an Interest Period
other than seven (7) or fourteen (14) days, the Borrowers shall be deemed to
have repaid all outstanding Eurodollar Rate Loans as of the effective date of
such assignment and reborrowed such amount as a Floating Rate Loan and/or
Eurodollar Rate Loan (chosen in accordance with the provisions of Section 4.7)
and the indemnification provisions under this Section 5.5 shall apply.


                                  ARTICLE VI.

                        REPRESENTATIONS AND WARRANTIES

        Each Borrower hereby represents and warrants to the Administrative
Agent and the Banks that:

        6.1   Corporate Existence and Power.  Each of MascoTech and its
Domestic Subsidiaries is a corporation duly incorporated, validly existing and
in good standing under the laws of the State of its incorporation, and is duly
qualified as a foreign corporation in each State or other jurisdiction in the
United States of America in which the conduct of its operations or the
ownership of its properties requires such qualification and failure so to
qualify would materially and adversely affect MascoTech and its Subsidiaries
taken as a whole.  All of such corporations have all requisite corporate power
to own their properties and to carry on their businesses, considered as a
whole, substantially as now owned and as now being conducted.  Each of the
Borrowers has full power, authority and legal right to execute and deliver this
Agreement and the Notes, to perform and observe the terms and provisions hereof
and thereof, and to borrow hereunder.

        6.2   Corporate Authority; No Violations; Governmental Filings; Etc. 
The execution, delivery and performance by each of the Borrowers of this
Agreement, the issuance of the Notes and the borrowings hereunder have been
duly authorized by all necessary corporate action and do not and will not
violate the provisions of any applicable law or regulation or of the
certificate of incorporation or by-laws of MascoTech or any Subsidiary or any
order of any court, regulatory body or arbitral tribunal and do not and will
not result in the breach of, or constitute a default or require any consent
under, or create any lien, charge or encumbrance upon any property or assets of
MascoTech or any Subsidiary pursuant to, any indenture or other agreement or
instrument to which MascoTech or any Subsidiary is a party or by which
MascoTech or any Subsidiary or its property may be bound or affected.  Neither
the execution, delivery and performance of this Agreement nor the issuance of
the Notes nor any borrowing hereunder requires, for the validity thereof, nor
does the enforceability of this Agreement or any of the Notes require, any
filing with, or consent, authorization  or approval of, any state or federal
agency or regulatory authority, other than filings, consents or approvals which
have been made or obtained or which, in the case of any such borrowing, will be
made or obtained prior to the due date for such filing, consent or approval.  

                                       55
<PAGE>   63

        6.3   Binding Effect.  This Agreement constitutes, and the Notes when
executed and delivered by each Borrower for value will constitute, the legal,
valid and binding obligations of such Borrower, enforceable against such
Borrower in accordance with their respective terms.

        6.4   Litigation.  There are no suits, proceedings, or actions at law
or in equity or by or before any governmental commission, board, bureau, or
other administrative agency, pending or, to the knowledge of the Borrowers,
threatened against MascoTech or any of its Subsidiaries or affecting MascoTech
or any of its Subsidiaries, which, in the reasonable opinion of MascoTech,
either (i) are likely to have a material adverse effect on the financial
condition or business of MascoTech and its Subsidiaries taken as a whole or
(ii) will in any manner affect the enforceability or validity of this Agreement
or any Note.

        6.5   Taxes.  MascoTech and each Subsidiary has filed (or has obtained
extensions of the time by which it is required to file) all United States
federal income tax returns, and all other tax returns which are required to be
filed and are material to the business, operations or financial position of
MascoTech and its Subsidiaries taken as a whole, and has paid all taxes shown
due pursuant to such returns or pursuant to any assessment received by
MascoTech or any Subsidiary, except such taxes, if any, as are being contested
in good faith and as to which, in the reasonable opinion of MascoTech, adequate
reserves have been provided in accordance with generally accepted accounting
principles.  MascoTech does not know of any proposed tax assessment against it
or any Subsidiary or of any basis for one, except to the extent any such
assessment has been, in the reasonable opinion of MascoTech, adequately
provided for in the consolidated tax reserves of MascoTech and its Subsidiaries
in accordance with generally accepted accounting principles.

        6.6   Financial Condition.  The consolidated balance sheet of MascoTech
and its Consolidated Subsidiaries and consolidated statements of income,
shareholders' equity and cash flows of MascoTech and its Consolidated
Subsidiaries for the fiscal year ended December 31, 1996, certified by Coopers
& Lybrand, independent certified public accountants, and the interim unaudited
consolidated balance sheet and interim unaudited consolidated statements of
income, shareholders' equity and cash flows of MascoTech and its Consolidated
Subsidiaries, as of or for the nine-month period ended on September 30, 1997,
copies of which have been furnished to the Banks, fairly present the
consolidated financial position of MascoTech and its Consolidated Subsidiaries
as at the dates thereof, and the consolidated results of operations of
MascoTech and its Consolidated Subsidiaries for the respective periods
indicated, all in accordance with generally accepted accounting principles
consistently applied (except as disclosed in the notes thereto and subject, in
the case of interim statements, to year-end audit adjustments).  Except as
disclosed in the financial statements as of or for the nine-month period ended
September 30, 1997, there has been no material adverse change in the
consolidated operations or condition, financial or otherwise, of MascoTech and
its Consolidated Subsidiaries considered as a whole, since December 31, 1996.

        6.7   Compliance with ERISA.  Each of MascoTech and each ERISA
Affiliate of MascoTech (a) has fulfilled its obligations under the minimum
funding standards of ERISA and the 

                                       56
<PAGE>   64

Code with respect to each Plan and (b) is in compliance in all  material
respects with the presently applicable provisions of ERISA and the Code with
respect to each Plan.  Neither MascoTech nor any ERISA Affiliate of MascoTech
has (x) sought a waiver of the minimum funding standard under Section 412 of
the Code in respect of any Plan, (y) failed to make any contribution or payment
to any Plan or Multiemployer Plan or in respect of any Benefit Arrangement, or
made any amendment to any Plan or Benefit Arrangement, which has resulted or
could result in the imposition of a Lien or the posting of a bond or other
security under ERISA or the Code, in each case securing an amount greater than
$10,000,000, or (z) incurred any liability under Title IV of ERISA, other than
a liability to the PBGC for premiums under Section 4007 of ERISA, which could
materially adversely affect the business, consolidated financial position or
consolidated results of operations of MascoTech and its Consolidated
Subsidiaries.

        6.8   Environmental Matters.  In the ordinary course of its business,
MascoTech conducts appropriate reviews of the effect of Environmental Laws on
the business, operations and properties of MascoTech and its Subsidiaries, in
the course of which it identifies and evaluates pertinent liabilities and costs
(including, without limitation, capital or operating expenditures required for
clean-up or closure of properties presently or previously owned or for the
lawful operation of its current facilities, required constraints or changes in
operating activities, and evaluation of liabilities to third parties, including
employees, together with pertinent costs and expenses).  On the basis of this
review, MascoTech has reasonably concluded that Environmental Laws are not
likely to have a material adverse effect on the business, financial position or
results of operations of MascoTech and its Consolidated Subsidiaries,
considered as a whole.

        6.9   Compliance with Laws.  MascoTech complies, and has caused each
Subsidiary to comply, in all material respects with all applicable laws,
ordinances, rules, regulations, and requirements of governmental authorities
(including, without limitation, Environmental Laws and ERISA and the rules and
regulations thereunder), except where (a) the necessity of compliance therewith
is contested in good faith by appropriate proceedings and MascoTech has
established appropriate reserves for liability for noncompliance therewith in
accordance with generally accepted accounting principles, (b) no officer of
MascoTech is aware that MascoTech or the relevant Subsidiary has failed to
comply therewith, or (c) MascoTech has reasonably concluded that failure to
comply is not likely to have a material adverse effect on the business,
financial position or results of operations of MascoTech and its Consolidated
Subsidiaries, taken as a whole.

        6.10  Subordinated Debt.  The existing Subordinated Debt evidenced by
the 41/2% Convertible Subordinated Debentures due 2003 in the original
principal amount of $345,000,000 is and shall be subordinated to all Loans
under this Agreement on the same terms that are applicable to the Existing Bank
Facility.

                                 ARTICLE VII.

                                   COVENANTS

        Until all the Commitments and Letters of Credit have expired or been
terminated and all Loans and reimbursement and other obligations (other than
contingent indemnification obligations) of the Borrowers hereunder have been
paid in full, each of the Borrowers covenants that:

        7.1   Financial Statements.  MascoTech will deliver to each of the

Consolidated Subsidiaries, for the period commencing at the end of the previous
fiscal year and ending with the end of such quarter, setting forth in each of
the statements required by this subsection (a), in comparative form,
corresponding figures as of the end of and for the corresponding period of the

year-end audit adjustments) by the chief financial officer or chief accounting
officer of MascoTech as having been prepared in all material respects in

presentation; 

              (b)  as soon as practicable and in any event within 95 days after
the end of each fiscal year of MascoTech, (i) a consolidated balance sheet of
MascoTech and its Consolidated Subsidiaries, as at the end of such year, and
(ii) consolidated statements of income, shareholders' equity, and cash flows of
MascoTech and its Consolidated Subsidiaries for such year, setting forth in

corresponding figures as of the end of and for the preceding fiscal year, and
all in reasonable detail and certified without material qualifications by
Coopers & Lybrand, or by other independent certified public accountants of
recognized national standing selected by MascoTech and reasonably acceptable to
the Administrative Agent;

              (c)   as soon as practicable and in any event within 30 days after
the sending or filing thereof, copies of all such financial statements and
reports as it shall send to its security holders and of all final       
prospectuses under the Securities Act of 1933 (other than form S-8), reports on
forms 10-Q, 10-K and 8-K and all similar regular and periodic reports filed by
it (i) with any federal department, bureau, commission or agency from time to
time having jurisdiction with respect to the sale of securities or (ii) with
any securities exchange;

              (d)   if and when MascoTech or any ERISA Affiliate of MascoTech 
(i) gives or is required to give notice to the PBGC of any "reportable event" 
(as defined in Section 4043 of ERISA) with respect to any Plan which might
constitute grounds for a termination of such Plan under Title IV of ERISA, or
knows that the plan administrator of any Plan has given or is required to give
notice of any such reportable event, a copy of the notice of such reportable
event given or required to be given 

                                       58
<PAGE>   66

to the PBGC; (ii) receives notice of complete or partial withdrawal
liability under Title IV of ERISA or notice that any Multiemployer Plan is in
reorganization, is insolvent or has been terminated, a copy of such notice;
(iii) receives notice from the PBGC under Title IV of ERISA of an intent to

such notice; (iv) applies for a waiver of the minimum funding standard under

to make any payment or contribution to any Plan or Multiemployer Plan or in
respect of any Benefit Arrangement or makes any amendment to any Plan or
Benefit Arrangement which has resulted or could result in the imposition of a
Lien or the posting of a bond or other security, a certificate of the chief
financial officer or the chief accounting officer of MascoTech setting forth
details as to such occurrence and action, if any, which MascoTech or applicable
ERISA Affiliate is required or proposes to take; provided that no such
certificate shall be required unless the aggregate unpaid actual or potential
liability of MascoTech and the ERISA Affiliates involved in all events referred
to in clauses (ii) through (vii) above of which officers of MascoTech have
obtained knowledge and have not previously reported under this subparagraph (d)
exceeds $15,000,000; and

              (e)   with reasonable promptness, such other information 
regarding the financial condition of MascoTech or any of its Subsidiaries
as any Bank may from time to time reasonably request.

        7.2   Certificates of No Default and Compliance.

              (a)   Concurrently with each delivery of the financial statements
pursuant to subsections (a) and (b) of Section 7.1, MascoTech will deliver to
the Administrative Agent (with a copy delivered to each Bank) a certificate,
signed by the chief accounting officer or chief financial officer of MascoTech
(i) stating that to the best of his knowledge after due inquiry, at the date of
such financial statements no Default had occurred and was continuing, or, if a
Default had occurred and was continuing, specifying the nature and period of
existence thereof and what action MascoTech has taken or proposes to take with
respect thereto; (ii) setting forth as of the date of such financial statements,
in reasonable detail, the calculations employed to determine compliance with
Sections 4.2(f) (but, in the case of any Asset Sale, only to the extent that the
aggregate amount of Net Cash Proceeds during the immediately preceding twelve
months exceeds $25,000,000), 7.4, 7.5, 7.6, 7.7, 7.8, 7.9 and 7.15 and an
explanation in reasonable detail of any differences between generally accepted
accounting principles as then in effect and generally accepted accounting
principles used in making such calculations, as may be permitted under Section
1.2.  The certificate will be accompanied by a calculation of the Senior Debt
Coverage Ratio as of the end of such fiscal quarter (calculated on a pro forma
basis as appropriate). 

              (b)  Within 60 days after the end of each fiscal quarter of each
fiscal year of MascoTech (including the last fiscal quarter of each fiscal
year), MascoTech will deliver to the Administrative Agent (with a copy delivered
to each Bank) a certificate, signed by the chief accounting 

                                       59
<PAGE>   67

officer, chief financial officer, treasurer or assistant treasurer of
MascoTech, setting forth in reasonable detail the calculation of the
Leverage Ratio, as of the Determination Date with respect to the next
forthcoming Application Period, and identifying the Applicable Margin for such
Application Period as a result of such calculations.

              (c)   Within fifteen Business Days after any officer of MascoTech
obtains knowledge of a Default, MascoTech will, unless the same shall have been
cured within such fifteen Business Day period, give written notice to each of
the Banks thereof, specifying the nature thereof, the period of existence
thereof and what action MascoTech proposes to take with respect thereto.

        7.3   Preservation of Corporate Existence, Etc. MascoTech will preserve
and maintain its corporate existence, and qualify and remain qualified as a
validly existing corporation in good standing in each jurisdiction in which the
conduct of its operations or the ownership of its properties requires such
qualification and failure so to qualify would materially and adversely affect
MascoTech and its Subsidiaries taken as a whole.

        7.4   Minimum Capitalization.  MascoTech shall not permit its Adjusted
Net Worth at any time to be less than the sum of (a) $650,000,000 plus (b)
sixty percent (60%) of (i) Net Income calculated separately for each fiscal
year of MascoTech ending after the Closing Date minus (ii) the aggregate amount
of dividends paid on any preferred stock of MascoTech during such period to the
extent permitted by Section 7.15 minus (c) on or after March 31, 2002,
$200,000,000; provided however, that if such Net Income is negative in any
fiscal year, the amount added for such fiscal year shall be zero and such
negative Net Income shall not reduce the amount of such Net Income added for
any other fiscal year.  

        7.5   Fixed Charge Coverage Ratio.  MascoTech shall maintain a ratio
("Fixed Charge Coverage Ratio") as of the end of each fiscal quarter of (i)
EBITDA minus Capital Expenditures to (ii) the sum of the amounts of (a)
Interest Charges plus (b) scheduled amortization payments of the principal
portion of the Term Loans (exclusive of the installment due January 31, 2002)
and scheduled amortization payments of the principal portion of all other Debt
of MascoTech and its Consolidated Subsidiaries with an original maturity in
excess of one year plus (c) cash taxes paid by MascoTech and its Consolidated
Subsidiaries (excluding cash taxes with respect to gains not included in
EBITDA) of at least:

              (i)  1.10 to 1.00 as of the last day of each fiscal
        quarter ending during the period commencing with the fiscal quarter 
        ending March 31, 1998 through the fiscal quarter ending June 30, 2000; 
        and 

             (ii)  1.15 to 1.00 as of the last day of each fiscal quarter ending
        thereafter until the Termination Date.

In each case, the Fixed Charge Coverage Ratio shall be determined as of
the last day of each fiscal quarter for the four fiscal quarter period ending
on such day, except that Capital Expenditures shall be 

                                       60
<PAGE>   68

calculated using an amount equal to fifty percent of the Capital Expenditures
during the eight fiscal quarter period ending on such day.

        7.6   Maximum Leverage Ratio.  MascoTech shall not, as of the last day
of each fiscal quarter, permit the ratio (the "Leverage Ratio") of (i) the sum
of (a) the aggregate principal amount of Debt of MascoTech and its Consolidated
Subsidiaries outstanding at such date plus (b) the amount by which the sum of
the outstanding Synthetic Lease Amount and the outstanding Securitization
Amount exceeds $50,000,000 as of such date minus (c) the aggregate amount of
Cash and Cash Equivalents maintained in the United States in excess of
$10,000,000 as of such date to (ii) EBITDA plus an amount equal to any
reduction in EBITDA attributable to any interest, rental or servicing expense
related to any Synthetic Lease Agreement or Receivables Sale to the extent such
amounts are included in the amount in excess of $50,000,000 determined as
provided in clause (i)(b) of this Section 7.6, for the four fiscal quarters
then most recently ended, to be greater than the ratio set forth below opposite
such date:

      Quarter Ending                Ratio       

      March 31, 1998                4.85 to 1.00
      June 30, 1998                 4.85 to 1.00
      September 30, 1998            4.75 to 1.00
      December 31, 1998             4.50 to 1.00

      March 31, 1999                4.50 to 1.00

        7.7   Subsidiary Indebtedness. MascoTech will not permit or suffer the
aggregate principal amount of Debt of its Subsidiaries (other than Debt owing
to MascoTech or any of its Subsidiaries or Debt outstanding under this
Agreement or any Note) at any time to be greater than $100,000,000.

        7.8   Negative Pledge.  MascoTech shall not, nor shall MascoTech permit
any Consolidated Subsidiary to create, assume or suffer to exist any Lien on
any asset now owned or hereafter acquired by it, except:

              (a) Liens existing on the date of this Agreement securing Debt
        outstanding on the date of this Agreement in an aggregate principal 
        amount not exceeding $25,000,000;

              (b) any Lien existing on any asset of any corporation at the time
        such corporation becomes a Consolidated Subsidiary and not created in 
        contemplation of such event;

              (c) any Lien on any asset securing Debt incurred or assumed for 
        the purpose of financing all or any part of the cost of acquiring
        such asset (or acquiring a corporation or other entity which owned such 
        asset), provided that such Lien attaches to such asset concurrently 
        with or within 90 days after such acquisition;

              (d) any Lien on any asset of any corporation existing at the time
        such corporation is merged or consolidated with or into MascoTech
        or a Consolidated Subsidiary and not created in contemplation of such
        event;

              (e) any Lien existing on any asset prior to the acquisition 
        thereof by MascoTech or a Consolidated Subsidiary and not created in
        contemplation of such acquisition;

              (f) any Lien arising out of the refinancing, extension, renewal or
        refunding of any Debt secured by any Lien permitted by any of the
        foregoing clauses of this Section, provided that such Debt is not 
        increased and is not secured by any additional assets;

              (g) any Lien in favor of the holder of Debt (or any Person acting
        for or on behalf of such holder) arising pursuant to any order of
        attachment, distraint or similar legal process arising in connection 
        with court proceedings so long as the execution or other enforcement 
        thereof is effectively stayed and the claims secured thereby are being 
        contested in good faith by appropriate proceedings and MascoTech or 
        such Consolidated Subsidiary, as the case may be, has established 
        appropriate reserves against such claims in accordance with generally   
        accepted accounting principles;

              (h) Liens incidental to the normal conduct of its business or the
        ownership of its assets which (i) do not secure Debt and (ii) do
        not in the aggregate materially detract (due to the amount of the 
        liability secured by such Liens or otherwise) from the value of the 
        assets of MascoTech and its Consolidated Subsidiaries taken as a whole 
        or in the aggregate materially 

                                       62
<PAGE>   70

        impair the use thereof in the operation of the business of      
        MascoTech and its Consolidated Subsidiaries taken as a whole;

              (i) any Lien securing Debt incurred under this Agreement; and

              (j) Liens not otherwise permitted by the foregoing clauses of this
        Section; provided that (i) the aggregate outstanding principal amount 
        of Debt secured by all such Liens on Current Assets shall not at any 
        time exceed 10% of Current Assets and (ii) the aggregate outstanding 
        principal amount of Debt secured by all such Liens (including Liens 
        referred to in clause (i) of this proviso) shall not at any time exceed 
        the sum of 5% of Net Worth plus 10% of Current Assets, provided, 
        further, that for purposes of this Section 7.8(i), Current Assets 
        shall not include any assets that are classified as Current Assets 
        solely because they are held for sale;

provided, however, that the restrictions set forth in this Section 7.8 shall
not apply to "margin stock" (as defined in Regulation U of the Board of
Governors of the Federal Reserve System), if and to the extent that the value
of the margin stock with respect to which the rights of MascoTech and its
Subsidiaries are restricted by this Section 7.8 would otherwise exceed 25% of
the value of all assets with respect to which the rights of MascoTech and its
Subsidiaries are restricted by this Section 7.8.

        7.9   Dispositions of Assets; Mergers and Consolidations.

              (a)    (i)  MascoTech will not merge or consolidate with any other
Person, unless MascoTech shall be the continuing or surviving corporation of
such merger or consolidation.  (ii) No Consolidated Subsidiary of MascoTech
will merge or consolidate with any Person other than MascoTech (subject to
subsection (a)(i)) or another Consolidated Subsidiary, unless such Consolidated
Subsidiary shall be the continuing or surviving corporation, except to the
extent the sale of such Consolidated Subsidiary would be permitted pursuant to
subsection (b) of this Section.

              (b)   MascoTech will not, and will not permit any Consolidated

Subsidiary to, directly or indirectly sell, lease, transfer or  otherwise
dispose of its assets (other than the sale of inventory in the ordinary course
of business) if, immediately after giving effect thereto, the aggregate amount
of such assets (including the Receivables Sales Amount in the case of
Receivables Sales) sold, leased, transferred or otherwise disposed of by
MascoTech and its Consolidated Subsidiaries in the twelve months then ended
would exceed 10% of the total assets of MascoTech and its Consolidated
Subsidiaries as shown on the most recent balance sheet delivered to the Banks
under Section 7.1; provided, however, that the restrictions set forth in this
Section 7.9(b) shall not restrict or prohibit sales of "margin stock" (as
defined in Regulation U of the Board of Governors of the Federal Reserve
System) for fair value as determined in good faith by the Board of Directors of
MascoTech, if and to the extent that the value of the margin stock with respect
to which the rights of MascoTech and its Subsidiaries are restricted by this
Section 7.9(b) would otherwise exceed 25% of the value of all assets with
respect to which the rights of MascoTech and its Subsidiaries are restricted by
this Section 7.9(b).  Other than margin stock consisting of the stock of TriMas
Corporation, MascoTech will not own, 

                                       63
<PAGE>   71

directly or through one or more of its Subsidiaries, margin stock with a
value in excess of 25% of the value of all assets of MascoTech and its
Subsidiaries.

              (c)   Notwithstanding any other provision of this Section 7.9, no
disposition of assets, merger or consolidation referred to in subsection (a) or
(b) of this Section shall be permitted if, immediately after giving effect
thereto, any Default would exist.

        7.10  Changes in Subordinated Debt.  MascoTech will not (a) transfer,
convey, assign or deliver to any holder of any Subordinated Debt, or to any
trustee, paying agent or other fiduciary for the benefit of the holder of any
Subordinated Debt (including any defeasance), any cash, securities (other than
securities constituting Subordinated Debt) or other assets of MascoTech or any
Subsidiary in payment or on account of, or as provision for, principal,
premium, if any, or interest on any Subordinated Debt which is not required
under the instruments and agreements relating to such Subordinated Debt
(provided that any payment which is blocked by any creditors of MascoTech or
any of its Subsidiaries pursuant to the terms of the applicable instrument or
agreement shall not be deemed to be required) or (b) or amend, modify or waive
any term or provision of any instrument or agreement relating to any
Subordinated Debt such that it would not constitute "Subordinated Debt" as
defined herein if at the time of any such transfer, conveyance, assignment,
delivery, amendment, modification or waiver there shall exist and be
continuing, or if immediately after giving effect thereto as a reasonably
foreseeable result thereof on a pro forma basis there would exist or would be
caused thereby, a Default.

        7.11  Use of Proceeds.  (a)  None of the proceeds of the Loans made
under this Agreement will be used in violation of any applicable law or
regulation including, without limitation, Regulation U of the Board of
Governors of the Federal Reserve System, provided that a Federal Reserve Form
U-1 shall have been completed by the Administrative Agent on behalf of each
Bank and reviewed and approved by the Banks in form and substance satisfactory
to MascoTech and the Administrative Agent on or prior to the Closing.

              (b)  The proceeds of the Loans made under this Agreement shall be
used (i) to refinance the Existing Bank Facility, (ii) to finance the
purchase of capital stock of the Target acquired pursuant to the Tender Offer,
(iii) to finance the Merger, (iv) to refinance the current credit facilities of
the Target and (v) for general corporate purposes of the Borrowers.

        7.12  Fiscal Year.  MascoTech will not change its fiscal year from
beginning on January 1 of the calendar year and ending on December 31 of the
calendar year.

        7.13  Compliance with Laws.  MascoTech will comply, and cause each
Subsidiary to comply, in all material respects with all applicable laws,
ordinances, rules, regulations, and requirements of governmental authorities
(including, without limitation, Environmental Laws and ERISA and the rules and
regulations thereunder) except where (a) the necessity of compliance therewith
is contested in good faith by appropriate proceedings, (b) no officer of
MascoTech is aware that MascoTech or the relevant Subsidiary has failed to
comply therewith or (c) MascoTech has reasonably concluded that 

                                       64


<PAGE>   72

failure to comply is not likely to have a material adverse effect on the
business, financial position or results of operations of MascoTech and its
Consolidated Subsidiaries, taken as a whole.

        7.14  Interest Rate Agreements.   Not later than 180 days after the
Closing Date, the Borrowers shall enter into, and shall thereafter maintain
interest rate swap or hedging agreements or other agreements (including (i) new
Financing of either debt securities bearing a fixed rate of interest or equity
securities) which effectively protect the Borrowers against increases in
interest rates that the Borrowers may be required to pay on a notional amount
of not less than $200,000,000 for not less than the first two years following
the Closing Date.

        7.15  Restricted Payments.  At any time that MascoTech's Leverage Ratio
(calculated as prescribed in Section 7.6 for the most recently completed four
fiscal quarter period, but adjusted to reflect on a pro forma basis the effect
on the Debt of MascoTech and its Consolidated Subsidiaries as a result of any
issuance of Equity Interests or trust convertible debt securities or similar
securities made subsequent to such period but on or prior to the date such
Restricted Payment is to be made) is greater than or equal to 3.0 to 1.0,
MascoTech shall not make any Restricted Payment except:  (i) the payment of
dividends on preferred stock in an amount not to exceed $3,750,000 in any one
fiscal quarter, (ii) other Restricted Payments not to exceed in the aggregate
during the term of this Agreement an amount equal to the sum of (a) $40,000,000
plus (b) an amount equal to 75% of any proceeds received by MascoTech in
connection with its issuance of Equity Interests or trust convertible debt
securities or similar securities to the extent such securities are not treated
as debt of MascoTech in accordance with generally accepted accounting
principles to the extent that, after giving pro forma effect to the application
of a portion of such proceeds to Senior Debt, the Senior Debt Coverage Ratio is
less than 3.0 to 1.0 plus (c) an amount equal to 60% of any proceeds received
by MascoTech in connection with the issuance of Subordinated Debt or trust
convertible debt securities or similar securities to the extent such securities
are treated as debt of MascoTech in accordance with generally accepted
accounting principles to the extent that, after giving pro forma effect to the
application of a portion of such proceeds to Senior Debt,  the Senior Debt
Coverage Ratio is less than 3.0 to 1.0 plus (d) an amount equal to 50% of the
aggregate amount of the Excess Cash Flow of MascoTech and its Consolidated
Subsidiaries in each fiscal quarter following the Closing Date and ending with
the most recently completed fiscal quarter (or, 100% of such Excess Cash Flow
for any fiscal quarter ending on or after the Senior Debt Coverage Ratio is
less than 3.0 to 1.0), provided, however, that the Restricted Payments
described in clauses (i) and (ii) above shall not be permitted if either an
Event of Default or a Default shall have occurred and be continuing at the date
of declaration or payment thereof or would result therefrom, except that any
dividends on the common or preferred stock of MascoTech which are declared at a
time when no Default or Event of Default shall have occurred and be continuing
or would result therefrom, MascoTech shall be entitled to pay such dividend
within sixty (60) days of such declaration.

        7.16  Guaranties and Pledges.  (a)  Prior to the consummation of the
Merger, MascoTech will (and, if at the expiration of the Tender Offer,
MascoTech and Acquisition have not obtained sufficient shares of the Target to
effect a short-form merger, MascoTech Sintered Components, Inc. ("Sintered"),
MascoTech Sintered Components of Indiana, Inc. ("Sintered Indiana") and
MascoTech 

                                       65
<PAGE>   73

Tubular Products, Inc. ("Tubular Products") will within five business days of
the initial funding to purchase shares of the Target pursuant to the Tender
Offer) guaranty the indebtedness under this Agreement pursuant to a guaranty
substantially in the form of Exhibit Q.  The guaranties by Sintered, Sintered
Indiana and Tubular Products will be released automatically after the
consummation of the Merger unless Sintered, Sintered Indiana and Tubular
Products are Significant Subsidiaries.  Within five Business Days after the
Merger becomes effective, the entity resulting from the Merger and all
Significant Subsidiaries will guaranty the indebtedness under this Agreement
pursuant to a guaranty substantially in the form of Exhibit Q.  Any subsidiary
that thereafter becomes a Significant Subsidiary will guaranty the indebtedness
under this Agreement promptly upon receiving written demand from the
Administrative Agent.  MascoTech will notify the Administrative Agent within
ninety-five (95) days of the date it is determined that any Subsidiary has
become a Significant Subsidiary.  The guaranty of any such Subsidiary will be
automatically released upon the sale of such Subsidiary if all Net Cash
Proceeds of the sale are applied to the Term Loans, or, if the Term Loans have
been paid in full, to the Revolving Loans, as prescribed in Section 4.2(f). 
The guaranty of any Subsidiary that ceases to be a Significant Subsidiary will
be automatically released upon the determination by MascoTech, in the
preparation of its annual financial statements, that such Subsidiary is no
longer a Significant Subsidiary.

              (b)  All stock of the Target owned by MascoTech, Acquisition and 
NI Industries, Inc., a Delaware corporation, including the stock acquired
in the Tender Offer, will be pledged concurrently with the initial Borrowing. 
The pledged stock will be released upon MascoTech's achievement of an implied
or actual senior unsecured debt rating of BB+ by S&P or Ba1 by Moody's or a
Senior Debt Coverage Ratio of less than 2.5 to 1.0, but not before the
consummation of the Merger.

<PAGE>   75

under the Revolving Credit Facility or the initial Borrowing under the Term
Loan Facility to finance the purchase of capital stock of the Target acquired
by Acquisition pursuant to the Tender Offer:

        (1)    (i)  Receipt by the Agents of evidence that MascoTech's
        directors shall have approved the Tender Offer and Merger and
        that the Target's directors shall have approved and recommended

        which filings, approvals or authorizations (or the expiration of such
        waiting periods) are legally required to be obtained or made by them
        (or to have expired or terminated) prior to the consummation of the
        Tender Offer and which, if not obtained or made (or expired or
        terminated) would, individually or in the aggregate, have a reasonable
        probability of having a material adverse effect on MascoTech or the
        Target.

        (2)   No law or regulation shall have made consummation of the Tender   
        Offer or the Merger illegal or otherwise prohibited and no judgment,

        statute, anti-takeover statute or provision in the Target's certificate
        of incorporation or by-laws in order to consummate the Merger.

        any of its provisions waived by MascoTech in any respect material
        to the Banks without the approval of the Agents and there shall not
        have occurred or exist any breach or default by MascoTech material to
        the  Banks under the Merger Agreement.  Except for such inaccuracies or
        omissions the consequences of which do not singly or in the aggregate
        constitute a material adverse effect on the Target, the representations
        and warranties of the Target contained in the Merger Agreement shall be
        true in all respects at and as of the time shares are accepted for
        payment pursuant to the Tender Offer as if made at and as of such time

        and the Merger, MascoTech and its Consolidated Subsidiaries, including
        the Target, taken as a whole, is solvent and will be solvent subsequent
        to incurring the indebtedness in connection with the Tender Offer and

                        EVENTS OF DEFAULT AND REMEDIES


        9.1   Events of Default.  If any one or more of the following events
("Events of Default") shall have occurred and be continuing:

              (a)   Any Borrower shall fail to pay when due any installment of
        principal of any Note or shall fail to pay within five days of the due
        date thereof any interest on any Note or any facility fee, closing
        fee, Letter of Credit fee, or Agents and Arrangers fee payable under
        this Agreement, or any reimbursement obligation under Section 3.3
        (unless satisfied by the deemed disbursement of Floating Rate Loans);
        or

              (b)   Any Borrower shall fail to observe or perform any covenant
        contained in any of Sections 7.3 to 7.10 inclusive and 7.14 to 7.16 
        inclusive; or 

              (c)   Any Borrower shall fail to observe or perform any covenant 
        or agreement contained in this Agreement (other than those covered
        by clauses (a) and (b) above) for thirty (30) days after written notice
        thereof has been given to such Borrower by any Bank or the
        Administrative Agent; or

              (d)   Any representation or warranty of a Borrower or any officer 
        of a Borrower to the Banks contained herein or in any certificate,
        statement or report furnished to the Banks hereunder shall prove to
        have been incorrect or misleading in any material respect on the date
        when made or deemed made, provided that, if any representation and
        warranty deemed to have been made by a Borrower pursuant to the last
        sentence of Section 8.1 as to the satisfaction of the condition of
        borrowing set forth in clause (b)(i) of Section 8.1 shall have been
        incorrect solely by reason of the existence of an Event of Default of
        which such Borrower was not aware when such representation and warranty
        was deemed to have been made and which was cured before or promptly
        after the Borrower became aware thereof, then such representation and
        warranty shall be deemed not to have been incorrect in any material
        respect; or

              (e)   Any Borrower or any Significant Subsidiary (i) shall fail to
        pay at maturity, or within any applicable period of grace, any  Debt
        (other than a Loan and other than Acquired Debt in an aggregate
        outstanding principal amount not exceeding $15,000,000) having an
        aggregate principal amount in excess of $10,000,000, and such failure
        has not been waived, or (ii) shall fail to observe or perform any term,
        covenant or agreement (other than such a term, covenant or agreement to
        or for the benefit of a Bank or Affiliate thereof restricting the sale,
        pledge or other disposition by a Borrower or any Significant Subsidiary
        of "margin stock" having a value in excess of 25% of the value of the
        assets referred to in Section 221.2(g)(2)(i)

        of Regulation U unless the Board of Governors of the Federal Reserve
        System or its staff advises the Administrative Agent in writing that
        the existence of this subsection (e) without this parenthetical
        exception would not in such circumstances render this Agreement
        "secured directly or indirectly by margin stock" within the  meaning of
        its Regulation U), contained in any agreement (other than this
        Agreement) by which it is bound evidencing or securing indebtedness for
        borrowed money (other than Acquired Debt in an aggregate        
        outstanding principal amount not exceeding $15,000,000) for such period
        of time as would cause or permit the holder or holders (or any Persons
        acting for or on behalf of such holder or holders) thereof or of any
        obligations issued thereunder to accelerate the maturity thereof or of
        any such obligations in an aggregate principal amount in excess of
        $10,000,000, and such failure has not been waived; provided that for
        purposes of this subsection (e), a failure by any Borrower or any
        Significant Subsidiary to observe or perform any term, covenant or
        agreement in respect of the industrial revenue bonds identified on
        Schedule 2 attached hereto, or to pay on the due date therefor the debt
        outstanding thereunder, shall not be deemed a Default or contribute to
        the $10,000,000 aggregate limitation set forth above, so long as such
        Borrower or Significant Subsidiary satisfies all obligations to pay
        premium, if any, principal of, and interest when due on such bonds
        (whether or not related to an acceleration of maturity) within five
        days after the due date therefor; or 

              (f)   Any Borrower or any Significant Subsidiary shall (i) apply 
        for or consent to the appointment of a receiver, custodian,
        trustee, liquidator or the like of itself or of a significant portion
        of its assets; (ii) be unable or admit in writing its inability to pay
        its debts as they mature; (iii) make a general assignment for the
        benefit of creditors; (iv) be adjudicated a bankrupt or insolvent; or
        (v) file a voluntary petition in bankruptcy or a petition or an answer
        seeking reorganization or an arrangement with creditors or to take 
        advantage of any insolvency law, or any answer admitting the material
        allegations of a petition filed against it in any bankruptcy,
        reorganization or insolvency proceedings, or a resolution of either the
        shareholders or the Board of Directors of such corporation shall be
        adopted for the purpose of effecting any of the foregoing; or

              (g)   A proceeding shall be instituted without the application,
        approval or consent of a Borrower or any Significant Subsidiary in any
        court of competent jurisdiction seeking, in respect of such Borrower or
        Significant Subsidiary, adjudication in bankruptcy, dissolution,
        winding up, reorganization, a composition or arrangement with
        creditors, a readjustment of debts, the appointment of a receiver,
        custodian, trustee, liquidator or the like of the Borrower or such
        Significant Subsidiary or of a significant portion of its assets, or
        other like relief in respect of the Borrower or Significant Subsidiary
        under any insolvency or bankruptcy law, and the same shall continue
        undismissed or unstayed and in effect for any period of sixty
        consecutive days; or

              (h)   Final judgment for the payment of money in excess of
        $5,000,000 in amount shall be rendered by a court of record against any 
        Borrower or Significant Subsidiary and such Borrower or Significant 
        Subsidiary shall not discharge the same or provide for its discharge, 
        or 

                                       72
<PAGE>   80

        procure a stay of execution thereof, within sixty days from the date of
        entry thereof, and within said period of sixty days or such longer
        period during which execution of such judgment shall have been stayed,
        move to vacate said judgment or appeal therefrom and cause the
        execution thereof to be stayed pending determination of such motion or
        during such appeal; or
 
              (i)   Any Borrower or any ERISA Affiliate of any Borrower shall 
        fail to pay when due an amount or amounts aggregating in excess of
        $5,000,000 which it shall have become liable to pay to the PBGC or to a
        Plan under Title IV of ERISA; or notice of intent to terminate a Plan
        or Plans having aggregate Unfunded Benefit Liabilities in excess of
        $25,000,000 (collectively, a "Material Plan") shall be filed under
        Title IV of ERISA by any Borrower or any ERISA Affiliate of any
        Borrower, any plan administrator or any combination of the foregoing;
        or the PBGC shall institute proceedings under Title IV of ERISA to
        terminate or to cause a trustee to be appointed to administer any
        Material Plan and such proceeding shall not have been dismissed within
        thirty days thereafter; or a condition shall exist by reason of which
        the PBGC would be entitled to obtain a decree adjudicating that any
        Material Plan must be terminated; or

              (j)(i) Any  Person or "group" (within the meaning of Section 13(d)
        or 14(d) of the Securities Exchange Act of 1934, as amended), other
        than any Person in the Masco Group or any group that includes any
        Person in the Masco Group (A) shall have acquired beneficial ownership
        of 25% or more of the capital stock having ordinary voting power in the
        election of directors of MascoTech or (B) shall obtain the power
        (whether or not exercised) to elect a majority of MascoTech's directors
        or (ii) the Board of Directors of MascoTech shall not consist of a
        majority of Continuing Directors; "Continuing Directors" shall mean the
        directors of MascoTech on the Closing Date and each other director, if
        such other director's nomination for election to the Board of Directors
        of MascoTech is recommended by a majority of the then Continuing
        Directors; or
          
              (k)  Acquisition and Target shall fail to consummate the Merger
        within 180 days of the initial funding of Loans;

then, and in each such case, the Administrative Agent upon being directed to do 
so by the Required Banks, shall, by written notice to the Borrowers, (i)
immediately terminate the Commitments, the Swing Line Commitment and the
Alternate Currency Commitments, (ii) declare the principal of and interest
accrued on all the Notes, all unpaid reimbursement obligations in respect of
drawings under Letters of Credit, and all other amounts owing under this
Agreement to be immediately due and payable or (iii) demand immediate delivery
of cash collateral, and the Borrowers agree to deliver such cash collateral
upon demand, in an amount equal to the maximum amount that may be available to
be drawn at any time prior to the stated expiry of all outstanding Letters of
Credit, or any one or more of the foregoing, whereupon the Commitments shall
terminate forthwith and all such amounts, including such cash collateral, shall
become immediately due and payable without presentment or demand for payment,
notice of non-payment, protest or further notice or demand of any kind, all of
which are expressly waived by the Borrowers; provided, however, that in the
case of the occurrence of any event 

                                       73
<PAGE>   81

described in the foregoing clauses (f) and (g) with respect to MascoTech or
with respect to the Target provided the Target is at such time a Borrower,
the Commitments shall automatically terminate forthwith and all such amounts,
including such cash collateral, shall automatically become immediately due and
payable without action upon the part of the Required Banks and without the
requirement of any such notice, and without presentment, demand, protest or
other notice of any kind, all of which are hereby waived.  Such cash collateral
delivered in respect of outstanding Letters of Credit shall be deposited in a
special cash collateral account to be held by the Administrative Agent as
collateral security for the payment and performance of the applicable
Borrower's obligations under this Agreement and the Notes to the Banks and the
Administrative Agent.

        9.2   Remedies.  The Administrative Agent upon being directed to do so
by the Required Banks, shall, in addition to the remedies provided in Section
9.1, exercise and enforce any and all other rights and remedies available to it
or the Banks, whether arising under this Agreement, the Notes or under
applicable law, in any manner deemed appropriate by the Administrative Agent,
including suit in equity, action at law, or other appropriate proceedings,
whether for the specific performance (to the extent permitted by law) of any
covenant or agreement contained in this Agreement or in the Notes or in aid of
the exercise of any power granted in this Agreement or the Notes.

        9.3   Set Off.  Upon the failure of the Borrowers to pay any
indebtedness under this Agreement or the Notes at its maturity (whether at
stated maturity, by acceleration or otherwise) or, in the case of such
indebtedness other than principal of the Loans, when due (after allowing for
any grace period provided with respect thereto under Section 9.1(a)), each Bank
may at any time and from time to time, without notice to the Borrowers (any
requirement for such notice being expressly waived by the Borrowers) set off
and apply against any and all of the obligations of the Borrowers now or
hereafter existing under this Agreement and the Notes, whether owing to such
Bank or any other Bank or the Administrative Agent, any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by such Bank to or for the credit or the
account of the Borrowers and any property of the Borrowers from time to time in
possession of such Bank, regardless of whether or not such Bank shall have made
any demand hereunder or any indebtedness owing by such Bank may be contingent
and unmatured.  The rights of the Banks under this Section 9.3 are in addition
to other rights and remedies (including, without limitation, other rights of
setoff) which the Banks may have.

                                  ARTICLE X.

                           THE AGENTS AND THE BANKS

        10.1  Appointment and Authorization.  Each Bank hereby irrevocably
appoints and authorizes the Administrative Agent to take such action as agent
on its behalf and to exercise such powers under this Agreement and the Notes as
are delegated to the Administrative Agent by the terms hereof or thereof,
together with all such powers as are reasonably incidental thereto.  The
provisions of this Article X are solely for the benefit of the Administrative
Agent and the Banks, and the Borrowers shall not have any rights as third party
beneficiaries of any of the provisions hereof.  In performing its functions and
duties under this Agreement, the Administrative Agent shall act solely as agent
of the Banks and does not assume and shall not be deemed to have assumed any
obligation towards or relationship of agency or trust with or for the
Borrowers.

        10.2  Administrative Agent and Affiliates.  The Administrative Agent in
its capacity as a Bank hereunder shall have the same rights and powers
hereunder as any other Bank and may exercise or refrain from exercising the
same as though it were not the Administrative Agent.  The Administrative Agent
and its Affiliates may (without having to account therefor to any Bank) accept
deposits from, lend money to, and generally engage in any kind of banking,
trust, financial advisory or other business with MascoTech or any Subsidiary of
MascoTech as if it were not acting as Administrative Agent hereunder, and may
accept fees and other consideration therefor without having to account for the
same to the Banks.

        10.3  Scope of Agent's Duties.  The Administrative Agent shall have no
duties or responsibilities except those expressly set forth herein, and shall
not, by reason of this Agreement, have a fiduciary relationship with any Bank,
and no implied covenants, responsibilities, duties, obligations or liabilities
shall be read into this Agreement or shall otherwise exist against the
Administrative Agent.  As to any matters not expressly provided for by this
Agreement (including, without limitation, collection and enforcement action
under the Notes), the Administrative Agent shall not be required to exercise
any discretion or take any action, but may request instructions from the
Required Banks.  The Administrative Agent shall in all cases be fully protected
from liability to the Banks in acting, or in refraining from acting, pursuant
to the written instructions of the Required Banks or, when expressly required
by this Agreement, all the Banks, which instructions and any action or omission
pursuant thereto shall be binding upon all of the Banks; provided,  however,
that the Administrative Agent shall not be required to act or omit to act if,
in the judgment of the Administrative Agent, such action or omission  may
expose the Administrative Agent to personal liability or is contrary to this
Agreement, any Note, or applicable law.  

        10.4  Reliance by Administrative Agent.  The Administrative Agent shall
be entitled to rely upon any certificate, notice, document or other
communication (including any cable, telegram, telex, facsimile transmission or
oral communication) believed by it to be genuine and correct and to have been
sent or given by or on behalf of a proper person.  The Administrative Agent may
treat the payee 

                                       75
<PAGE>   83

of any Note as the holder thereof.  The Administrative Agent may employ agents  
(including, without limitation, collateral agents)  and may consult with legal
counsel (who may be counsel for the Borrowers), independent public accountants
and other experts selected by it and shall not be liable to the Banks, except
as to money or property received by it or its authorized agents, for the
negligence or misconduct of any such agent selected by it with reasonable care
or for any action taken or omitted to be taken by it in good faith in
accordance with the advice of such counsel, accountants or experts.

        10.5  Default.  The Administrative Agent shall not be deemed to have
knowledge of the occurrence of any Default, unless the Administrative Agent has
received written notice from a Bank or the Borrowers specifying such Default
and stating that such notice is a "Notice of Default".  In the event that the
Administrative Agent receives such a notice, the Administrative Agent shall
give written notice thereof to the Banks.  

        10.6  Liability of Administrative Agent.  Neither the Administrative
Agent nor any of its directors, officers, agents, or employees shall be liable
to the Banks for any action taken or not taken by it or them in connection
herewith with the consent or at the request of the Required Banks or, when
expressly required by this Agreement, all the Banks or in the absence of its or
their own gross negligence or willful misconduct.  Neither the Administrative
Agent nor any of its directors, officers, agents or employees shall be
responsible for or have any duty to ascertain, inquire into or verify (a) any
recital, statement, warranty or representation contained in this Agreement or
any Note, or in any certificate, report, financial statement or other document
furnished in connection with this Agreement, (b) the performance or observance
of any of the covenants or agreements of the Borrowers, (c) the satisfaction of
any condition specified in Article VIII, except as to the delivery to the
Administrative Agent of documents that appear on their face to conform to the
requirements of Article VIII (other than requirements of any Bank under Section
8.3(b) that are not known to the Administrative Agent), or (d) the validity,
effectiveness, legal enforceability, value or genuineness of this Agreement,
the Notes, or any  other instrument or document furnished in connection
herewith.  

        10.7  Nonreliance on Administrative Agent and Other Banks.  Each Bank
acknowledges and agrees that it has, independently and without reliance on the
Administrative Agent or any other Bank, and based on such documents and
information as it has deemed appropriate, made its own credit analysis of
MascoTech and its Subsidiaries and its own decision to enter into this
Agreement, and that it will, independently and without reliance upon the
Administrative Agent or any other Bank, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
analysis and decision in taking or not taking action under this Agreement.  The
Administrative Agent shall not be required to keep itself informed as to the
performance or observance by the Borrowers of this Agreement, the Notes or any
other documents referred to or provided for herein or to inspect the properties
or books of the Borrowers and, except for notices, reports and other documents
and information expressly required to be furnished to the Banks by the
Administrative Agent hereunder, the Administrative Agent shall not have any
duty or responsibility to provide any Bank with any information concerning the
affairs, financial condition or business of MascoTech or any of its
Subsidiaries which may come into the possession of the Administrative Agent or
any of its Affiliates. 

                                       76
<PAGE>   84

        10.8  Indemnification.  The Banks agree to indemnify the Administrative
Agent (to the extent not reimbursed by the Borrowers, but without limiting any
obligation of the Borrowers to make such reimbursement), ratably according to
their respective Pro Rata Shares from and against any and all claims, damages,
losses, liabilities, costs or expenses of any kind or nature whatsoever
(including, without limitation, fees and disbursements of counsel) which may be
imposed on, incurred by, or asserted against the Administrative Agent in any
way relating to or arising out of this Agreement or the transactions
contemplated hereby or any action taken or omitted by the Administrative Agent
under this Agreement; provided, however, that no Bank shall be liable for any
portion of such claims, damages, losses, liabilities, costs or expenses
resulting from the Agent's gross negligence or willful misconduct.  Without
limitation of the foregoing, each Bank agrees to reimburse the Administrative
Agent promptly upon demand for its ratable share of any out-of-pocket expenses
(including, but not limited to, reasonable fees and expenses of counsel)
incurred by  the Administrative Agent in connection with the preparation,
execution, delivery, administration, modification, amendment or enforcement
(whether through negotiations, legal proceedings or otherwise) of, or legal
advice in respect of rights or responsibilities under, this Agreement, to the
extent that the Administrative Agent is not reimbursed for such expenses by the
Borrowers, but without limiting the obligation of the Borrowers to make such
reimbursement; provided, however, that no Bank shall be liable for any portion
of such expenses incurred as a result of the  Agent's gross negligence or
willful misconduct.  Each Bank agrees to reimburse the Administrative Agent
promptly upon demand for its ratable share of any amounts owing to the
Administrative Agent by the Banks pursuant to this Section; provided that no
Bank shall be responsible for failure of any other Bank to make such share
available to the Administrative Agent.  If the indemnity furnished to the
Administrative Agent under this Section shall, in the reasonable judgment of
the Administrative Agent, be insufficient or become impaired, the
Administrative Agent may call for additional indemnity from the Banks (other
than for the Agent's gross negligence or willful misconduct) and cease, or not
commence, to take any action until such additional indemnity is furnished.  

        10.9  Resignation of Administrative Agent.  The Administrative Agent
may resign as such at any time upon thirty days' prior written notice to the
Borrowers and the Banks.  In the event of any such resignation, the Required
Banks shall, by an instrument in writing delivered to the Borrowers and the
Administrative Agent, appoint a successor, which shall be (a) a Bank or (b) a
commercial bank organized under the laws of the United States or any State
thereof and having a combined capital and surplus of at least $500,000,000.  If
a successor is not so appointed or does not accept such appointment before the
Agent's resignation becomes effective, the resigning Administrative Agent may
appoint a temporary successor to act until such appointment by the Required
Banks is made and accepted or if no such temporary successor is appointed as
provided above by the resigning Administrative Agent, the Required Banks shall
thereafter perform all the duties of the Administrative Agent hereunder until
such appointment by the Required Banks is made and accepted.  Any successor to
the Administrative Agent shall execute and deliver to the Borrowers and the
Banks an instrument accepting such appointment and thereupon such successor
Administrative Agent, without further act, deed, conveyance or transfer shall
become vested with all of the properties, rights, interests, powers,
authorities and obligations of its predecessor hereunder with like effect as if
originally named as Administrative Agent hereunder.  Upon request of such
successor Administrative Agent, the 

                                       77
<PAGE>   85

Borrowers and the resigning Administrative Agent shall execute and deliver such 
instruments of conveyance, assignment and further assurance and do such other
things as may reasonably be required for more fully and certainly vesting and
confirming in such successor Administrative Agent all such properties, rights,
interests, powers, authorities and obligations.  The provisions of this Article
X shall thereafter remain effective for such resigning Administrative Agent
with respect to any  actions taken or omitted to be taken by such
Administrative Agent while acting as the Administrative Agent hereunder.

        10.10 Sharing of Payments.  The Banks agree among themselves that, in
the event that any Bank shall obtain payment in respect of any Loan or Letter
of Credit reimbursement obligation owing to such Bank under this Agreement
through the exercise of a right of set-off, banker's lien, counterclaim or
otherwise in excess of its ratable share as provided for in this Agreement,
such Bank shall promptly purchase from the other Banks participations in such
Loans and other obligations in such amounts, and make such other adjustments
from time to time, as shall be equitable to the end that all of the Banks share
such payment in accordance with their respective  ratable shares as provided
for in this Agreement.  The Banks further agree among themselves that if
payment to a Bank obtained by such Bank through the exercise of a right of
set-off, banker's lien, counterclaim or otherwise as aforesaid shall be
rescinded or must otherwise be restored, each Bank which shall have shared the
benefit of such payment shall, by repurchase of participations theretofore
sold, return its share of that benefit to each Bank whose payment shall have
been rescinded or otherwise restored, together with interest thereon at the per
annum rate, if any, at which such Bank whose payment shall have been restored
is liable with respect to such restored payment.  The Borrowers agree that any
Bank so purchasing such a participation may, to the fullest extent permitted
by law, exercise all rights of payment, including set-off, banker's lien or
counterclaim, with respect to such participation as fully as if such Bank were
a holder of such Loan or other obligation in the amount of such participation.
The Banks further agree among themselves that, in the event that amounts
received by the Banks and the Administrative Agent hereunder are insufficient
to pay all such obligations when due, the fees and other amounts owing to the
Administrative Agent in such capacity shall be paid therefrom before payment of
obligations owing to the Banks under this Agreement.  Except as otherwise
expressly provided in this Agreement, if any Bank or the Administrative Agent
shall fail to remit to the Administrative Agent or any other Bank an amount
payable by such Bank or the Administrative Agent to the Administrative Agent or
such other Bank pursuant to this Agreement on the date when such amount is due,
such payments shall be made together with interest thereon for each date from
the date such amount is due until the date such amount is paid to the
Administrative Agent or such other Bank at a rate per annum equal to the rate
at which borrowings are available to the payee in its overnight federal funds
market.

        10.11 Withholding Tax Exemption.  Each Bank agrees to file with the
Administrative Agent and the Borrowers, in duplicate, (a) on or before the
later of (i) the Closing Date and (ii) the date such Bank becomes a Bank under
this Agreement, (b) on the date such Bank becomes an Alternate Currency Bank
with respect to an Alternate Currency and (c) thereafter as frequently as
required by applicable law unless not legally able to do so as a result of a
change in applicable tax law enacted, or treaty promulgated, after the date
specified in the preceding clause (a) or (b), as applicable, on or prior to the
immediately following due date of any payment by the Borrowers hereunder, a
properly 

                                       78

completed and executed copy of any form, certification or similar
documentation,  if any, necessary for claiming complete exemption from
withholding taxes, including in the case of taxes imposed by the United States,
either Internal Revenue Service Form 4224 or Internal Revenue Service Form 1001
and Internal Revenue Service Form W-8 or Internal Revenue Service Form W-9 and
any additional form necessary for claiming complete exemption from United
States withholding taxes (or such other form as is required to claim complete
exemption from United States withholding taxes), if and as provided by the Code
or other pronouncements of the United States Internal Revenue Service, and such
Bank warrants to the Borrowers that the form so filed will be true and
complete; provided that such Bank's failure to complete, execute and file such
form, certification or similar documentation shall not relieve the Borrowers of
any of their obligations under this Agreement, other than their obligation
under Section 5.3(a) with respect to increased costs that are a result of such
failure.

        10.12   The Syndication Agents and Arrangers.  Each Syndication Agent
and Arranger, in such capacities, shall have no authority, duties,
responsibilities, obligations, liabilities or functions under this Agreement or
the Notes.


                                  ARTICLE XI.

                                 MISCELLANEOUS

        11.1    Amendments, Etc.

                (a)   No amendment, modification, termination or waiver of any
provision of this Agreement nor any consent to any departure therefrom shall
be effective unless the same shall be in writing and signed by the Borrowers
(except with respect to waivers by the Required Banks or all the Banks) and the
Required Banks and, to the extent any rights or duties of the Administrative
Agent may be affected thereby, by the Administrative Agent, provided, however,
that no such amendment, modification, termination, waiver or consent shall,
without the consent of all of the Banks, (i) authorize or permit the extension
of time for, or any reduction of the amount of, any payment of the principal
of, or interest (including the Applicable Margin) on, any Loan, or any fees or
other amount payable hereunder (except with respect to any modifications of the
provisions relating to prepayments of Loans and except with respect to waiving
the application of the Overdue Rate), or (ii) except as expressly authorized
hereunder, amend, extend or terminate the respective Commitment of any Bank
(other than any Alternate Currency Commitment and except for an extension
beyond the Termination Date), or (iii) modify the provisions of this Section
regarding the taking of any action under this Section, or the definition of
Required Banks, or (iv) permit the Borrowers to assign their rights under this
Agreement, or (v) release all or substantially all of any collateral securing
the extension or maintenance of the credit provided for in this Agreement or
release any guaranty thereof (except as expressly provided in Section 7.16), or
(vi) modify the several nature of the obligations of the Banks hereunder,
modify the sharing provisions among the Banks in Section 10.10, modify this
Section 11.1 or the first sentence of Section 11.6, or modify any other
provision of this Agreement which by its terms requires the consent of all the
Banks.

<PAGE>   87

              (b)   Any such amendment, waiver or consent shall be effective 
only in the specific instance and for the specific purpose for which given.

              (c)   Notwithstanding anything herein to the contrary, no Bank 
that is in default of any of its obligations, covenants or agreements under
this Agreement shall be entitled to vote (whether to consent or to withhold its
consent) with respect to any amendment, modification, termination or waiver of
any provision of this Agreement or any departure therefrom or any direction
from the Banks to the Administrative Agent, and, for purposes of determining
the Required Banks at any time when any Banks are in default under this
Agreement, the Commitments and Loans of such defaulting Banks shall be
disregarded; provided that no action of a type described in the proviso in
Section 11.1(a) shall be binding on a defaulting Bank without its written
consent thereto.  

        11.2  Notices.

              
              (a)   Except as otherwise provided in subsection 11.2(c) hereof, 
all notices and other communications to or upon the parties hereto shall be
deemed to have  been duly given or served if sent in writing (including
telecommunications) to the party to which such notice or other communication is
required or permitted to be given or served under this Agreement, to the
address or telex or telecopy number set forth below the name of such party on
the signature pages hereof, or at such other address or telex or telecopy
number as the parties hereto may hereafter specify to the others in writing. 
If for purposes of receiving Invitations for Bid-Option Quotes and information
regarding Notices of Bid-Option Rate Borrowings, a Bank wishes to receive such
communications at an address or telex or telecopy number different from its 
address or telex or telecopy number for other purposes under this Agreement,
the Administrative Agent shall communicate with such Bank for such purposes at
such different address, telex or telecopy number following the Administrative
Agent's receipt of a written notice from such Bank requesting that the
Administrative Agent do so.  All mailed notices or other communications shall
be by registered or certified mail, postage prepaid, with return receipt
requested.  All notices or other communications sent by means of telecopy,
telex or other wire transmission shall be made with request for assurance of
receipt in a manner typical with respect to communications of that type. 
Written notices or other communications shall be deemed delivered upon receipt
if delivered by hand, 3 Business Days after mailing if mailed, or 1 Business
Day after deposit with an overnight courier service if delivered by overnight
courier.  Notices or other communications provided by any of the other means
referred to above shall be deemed delivered upon receipt.  Notwithstanding the
foregoing, all notices to the Administrative Agent shall be effective only when
actually received by the Administrative Agent, and all notices from the
Administrative Agent to any Bank regarding such Bank's obligation to fund Loans
or to make payment under Section 3.3(d) shall be effective only when actually
received by such Bank.

              (b)   Notices by the Borrowers to the Administrative Agent with
respect to terminations or reductions of the Revolving Credit Commitments
pursuant to Section 3.10, requests for Loans and Letter of Credit Issuances
pursuant to Section 3.3, 3.4, 3.5, 3.6 or 3.7 and notices of prepayment pursuant
to Section 4.2 shall be irrevocable and binding on the Borrowers.

                                       80
<PAGE>   88

              (c)   Any notice to be given by the Administrative Agent or any 
Bank to the Administrative Agent or any Bank hereunder, may be given by 
telephone, and shall be promptly confirmed in writing upon the request of
the recipient.  Any such notice so given by telephone shall be deemed effective
upon receipt thereof by the party to whom such notice is to be given.

        11.3    No Waiver By Conduct; Remedies Cumulative.  No course of
dealing on the part of the Administrative Agent or any Bank, nor any delay or
failure on the part of the Administrative Agent or any Bank in exercising any
right, power or privilege hereunder or under any Note shall operate as a waiver
of such right, power or privilege or otherwise prejudice the Agent's or such
Bank's rights and remedies hereunder; nor shall any single or partial exercise
thereof preclude any further exercise thereof or the exercise of any other
right, power or privilege.  No right or remedy conferred upon or reserved to
the Administrative Agent or any Bank under this Agreement, or any Note, is
intended to be exclusive of any other right or remedy, and every right and
remedy shall be cumulative and in addition to every other right or remedy
granted hereunder or thereunder or now or  hereafter existing under any
applicable law.  Every right and remedy granted by this Agreement or by
applicable law to the Administrative Agent or any Bank may be exercised from
time to time and as often as may be deemed expedient by the Administrative
Agent or any Bank and, unless contrary to the express provisions of this
Agreement, or the Notes, irrespective of the occurrence or continuance of any
Default.

        11.4    Reliance on and Survival of Various Provisions.  All terms,
covenants, agreements, including, without limitation, under Sections 5.3, 5.5
and 11.5, representations and warranties of the Borrowers made herein or in any
certificate, report, financial statement or other document furnished by or on
behalf of the Borrowers pursuant to this Agreement shall be deemed to be
material and to have been relied upon by the Banks, notwithstanding any
investigation heretofore or hereafter made by any Bank or on such Bank's
behalf, and shall survive the repayment in full of the Loans and the
termination of the Commitments. 

        11.5    Expenses and Indemnification.

                (a)   The Borrowers shall pay, or reimburse the Administrative
Agent, Syndication Agents, Arrangers or any Bank, as the case may be
(each an "Indemnified Person"), for  (i) all reasonable out-of-pocket expenses
of the Administrative Agent, Syndication Agents and Arrangers, including
reasonable fees and disbursements of special counsel for the Administrative
Agent, Syndication Agents and Arrangers, in connection with the preparation of
this Agreement, any waiver or consent hereunder or any amendment hereof or any
Default, (ii) all reasonable costs and expenses of the Indemnified Person,
including reasonable fees and disbursements of counsel, in connection with any
action or proceeding relating to a court order, injunction or other process or
decree restraining or seeking to restrain the Administrative Agent from paying
any amount under, or otherwise relating in any way to, any Letter of Credit and
any and all costs and expenses which it may incur relative to any payment under
any Letter of Credit, provided, that the Borrowers shall not be liable under
this clause (ii) to the extent, but only to the extent, any such costs and
expenses of the Indemnified Person are caused by the Indemnified Person's
breach of this Agreement or gross negligence or willful misconduct, and (iii)
if an Event of Default occurs, all reasonable expenses incurred by the
Indemnified Person,  

                                     81
<PAGE>   89

including reasonable fees and disbursements of counsel (including       
in-house counsel), in connection with such Event of Default and collection and
other enforcement proceedings resulting therefrom.  The Borrowers shall
indemnify each Bank against any transfer taxes, documentary taxes, assessments
or charges made by any governmental authority by reason of the execution and
delivery of this Agreement or the Notes.

              (b)   The Borrowers shall indemnify each Indemnified Person, and 
its respective officers, directors, employees and agents, and hold each 
Indemnified Person, and its respective officers, directors, employees and
agents, harmless from and against any and all liabilities, losses, damages,
costs and expenses of any kind (including, without limitation, the reasonable
fees and disbursements of counsel for any Indemnified Person or any such Person
in connection with any investigative, administrative or judicial proceeding,
whether or not such Indemnified Person or any such Person, as the case may be,
shall be designated a party thereto) which may be incurred by any  Indemnified
Person or by any such Person, substantially relating to or arising out of any
actual or proposed use of proceeds of Loans or Letters of Credit for the
purpose of acquiring assets or capital stock of any other Person; provided that
no Indemnified Person or any such Person shall have the right to be indemnified
hereunder for its own gross negligence or willful misconduct as determined by a
court of competent jurisdiction.

              (c)   The Borrowers hereby further indemnify and agree to hold the
Indemnified Persons, and their respective officers, directors,  employees and
agents harmless from and against any and all claims, damages, losses,
liabilities, costs and expenses of any kind or nature whatsoever which the
Indemnified Persons or any such Person may incur or which may be claimed
against any of them by reason of or in connection with any Letter of Credit,
and no Indemnified Person or any of its respective officers, directors,
employees or agents shall be liable or responsible for:  (i) the use which may
be made of any Letter of Credit or for any acts or omissions of any beneficiary
in connection therewith; (ii) the validity, sufficiency or genuineness of
documents or of any endorsements thereon, even if such documents should in fact
prove to be in any or all respects invalid, insufficient, fraudulent or forged;
(iii) payment by the Administrative Agent to the beneficiary under any Letter
of Credit against presentation of documents which do not comply with the terms
of any Letter of Credit, including failure of any documents to bear any
reference or adequate reference to such Letter of Credit;  (iv) any error,
omission, interruption or delay in transmission, dispatch or delivery of any
message or advice, however transmitted, in connection with any Letter of
Credit; or (v) any other event or circumstance whatsoever arising in connection
with any Letter of Credit; provided, however, that the Borrowers shall not be
liable hereunder to the Indemnified Persons and such other Persons and the
Administrative Agent shall be liable to the Borrowers to the extent, but only
to the extent, of any direct, as opposed to consequential or incidental,
damages suffered by the Borrowers which were caused by (A) the Administrative
Agent's wrongful dishonor of any Letter of Credit after the presentation to it
by the beneficiary thereunder of a draft or other demand for payment and other
documentation strictly complying with the terms and conditions of such Letter
of Credit, or (B) the Administrative Agent's payment under any Letter of Credit
to the extent, but only to the extent, that such payment constitutes gross
negligence or willful misconduct of the Administrative Agent.  The inclusion of
any event in clauses (i) - (vii) of Section 3.3(f) shall not by itself preclude
a finding that such event

                                       82
<PAGE>   90

constitutes gross negligence or willful misconduct of the Administrative Agent.
It is understood that in making any payment under a Letter of Credit the
Administrative Agent will rely on documents presented to it under such Letter
of Credit as to any and all matters set forth therein without further
investigation and regardless of any notice or information to the contrary, and
such reliance and payment against documents presented under a Letter of Credit
substantially complying with the terms thereof shall not be deemed gross
negligence or willful misconduct of the Administrative Agent in connection with
the payment.  

        11.6    Successors and Assigns. 

                (a) This Agreement shall be binding upon and inure to 
the benefit of the parties hereto and their respective successors and assigns,
provided that the Borrowers may not, without the prior written consent of all
the Banks, assign its rights or obligations hereunder or under the Notes, and
the Banks shall not be obligated to make any Loan hereunder to any Person other
than the Borrowers, and the Administrative Agent shall not be obligated to
issue any Letter of Credit for the account of any Person other than MascoTech
or any Consolidated Subsidiary of MascoTech.
 
                (b) The Administrative Agent from time to time in its sole
discretion may appoint one of its affiliates as its agent for the purpose
of servicing and administering this Agreement and the transactions contemplated
hereby and enforcing or exercising any rights or remedies of the Administrative
Agent provided under this Agreement, the Notes or otherwise.  In furtherance of
such agency, the Administrative Agent may from time to time direct that the
Borrowers provide notices, reports and other documents contemplated by this
Agreement (or duplicates thereof) to such agent.  The Borrowers hereby consent
to the appointment of such agent and agrees to provide all such notices,
reports and other documents and to otherwise deal with such agent acting on
behalf of the Administrative Agent in the same manner as would be required if
dealing with the Administrative Agent itself.

                (c) Any Bank may sell a participation interest to any financial
institution(s), and such financial institution(s) may further sell a
participation interest (undivided or divided) to any financial institution(s),
in its Commitment and the Loans and risk of the Letters of Credit, Swing Line
Loans and Alternate Currency Syndicated Loans and such Bank's or such
participating financial institution's, as the case may be, rights and benefits
under this Agreement and the Notes, and to the extent of that participation,
such participant or participants shall have, to the extent permitted by law,
the same rights and benefits against the Borrowers under Section 9.3 as it or
they would have had if such participant or participants were the Bank making
the Loans to the Borrowers hereunder, provided, however, that in purchasing
such participation interest(s) each such participant shall be deemed to have
agreed to share with the Banks the proceeds thereof as provided in Section
10.10 as fully as if such participant were a Bank hereunder; and provided
further, however, that (i) the obligations under this Agreement of each Bank
selling a participation interest hereunder shall remain unmodified and fully
effective and enforceable against such Bank, (ii) such Bank shall remain solely
responsible to the other parties hereto for the performance of such
obligations, (iii) such Bank shall remain the holder of its Notes for all
purposes of this Agreement, (iv) the Borrowers, the Administrative Agent and
the other Banks shall 

                                       83
<PAGE>   91

continue to deal solely and directly with such Bank in connection with such
Bank's rights and obligations under this Agreement, and (v) such Bank shall not
grant to its participant(s) any rights to consent or withhold consent to any
action taken by such Bank or the Administrative Agent under this        
Agreement other than action requiring the consent of all of the Banks
hereunder.  Each Bank shall give the Borrowers prior written notice of each
sale by such Bank of a participation interest under this Section 11.6(c).  Each
participant shall be entitled to the benefits of Sections 5.3 and 5.5 with
respect to its participation interest as if it were a Bank; provided that no
participant shall be entitled to receive any greater amount pursuant to such
Sections 5.3 and 5.5 than the Bank that originally sold such participation
interest would have been entitled to receive in respect of such participation
interest had no such sale taken place.

                (d)   Any Bank may, with the prior written consent of the 
Borrowers and the Administrative Agent (which consent in each case will not
unreasonably be withheld or delayed, and which consent in the case of
MascoTech may not be withheld if there is any Event of Default under Section 
9.1(a), (f) or (g)) assign on a pro rata or non-rata basis to one or more banks 
or other financial institutions all or a portion of its rights and obligations 
under this Agreement (including, without limitation, all or a portion of its
Commitment, the Syndicated Loans owing to it, its share of the risk of Letters 
of Credit, Swing Line Loans and Alternate Currency Syndicated Loans, and the
Syndicated Notes held by it); provided, however, that (i) the amount of the
Commitment of any assignee Bank as of any date, after giving effect to each
assignment to such assignee that is effective on such date, shall in no event be
less than $10,000,000, (ii) except in the case of an assignment of all of a
Bank's rights and obligations under this Agreement, (A) the amount of the
Commitment of the assigning Bank being assigned pursuant to each such assignment
(determined as of the date of the Assignment and Acceptance with respect to each
such assignment) shall in no event be less than $5,000,000 or an integral 
multiple of $5,000,000, or such lesser amount as the Borrowers and the 
Administrative Agent may consent to and (B) after giving effect to each such 
assignment, the amount of the Commitment of the assigning Bank shall in no 
event be less than $10,000,000, (iii) the parties to each such assignment shall 
execute and deliver to the Administrative Agent, for its acceptance and 
recording in the Register (as hereinafter defined), an Assignment and
Acceptance in the form of Exhibit K hereto (an "Assignment and Acceptance"),
together with the Notes subject to such assignment and a processing and
recordation fee of $3,500, (iv) any Bank may without the consent of the
Borrowers or the Administrative Agent assign to any affiliate of such Bank all
of its rights and obligations under this Agreement and (v) any Bank may without
the consent of the Borrowers or the Administrative Agent assign any or all of
its rights and obligations under this Agreement to another Bank, as such term
is defined in this Agreement.  Upon such execution, delivery, acceptance and
recording, from and after the effective date specified in such Assignment and
Acceptance, (i) the assignee thereunder shall be a party hereto and, to the
extent that rights and obligations hereunder have been assigned to it pursuant
to such Assignment and Acceptance, have the rights and obligations of a Bank
hereunder and (ii) the Bank assignor thereunder shall, to the extent that
rights and obligations hereunder have been assigned by it pursuant to such
Assignment and Acceptance, relinquish its rights and be released from its
obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all of the remaining portion of an assigning Bank's rights
and obligations under this Agreement, such Bank shall cease to be a party
hereto).

                                       84
<PAGE>   92

                (e)   By executing and delivering an Assignment and Acceptance, 
(i) the Bank assignor thereunder and the assignee thereunder confirm to and
agree with each other and the other parties hereto as follows:  (A) other than
as provided in such Assignment and Acceptance, such assigning Bank makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or any instrument or other document furnished pursuant hereto or the
execution, legality, validity, enforceability, genuineness, sufficiency or
value of this Agreement or any instrument or other document furnished pursuant
hereto; and (B) such assigning Bank makes no representation or warranty and
assumes no responsibility with respect to the financial condition of the
Borrowers or the performance or observance by the Borrowers of any of their
obligations under this Agreement or any instrument or other document furnished
pursuant hereto, and (ii) the assignee thereunder confirms to the assignor
thereunder and the other parties hereto as follows: (A) such assignee confirms
that it has received a copy of this Agreement, together with copies of the
financial statements referred to in Section 6.6 and such other documents and
information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment and Acceptance; (B) such assignee will,
independently and without reliance upon the Administrative Agent, such
assigning Bank or any other Bank and based on such documents and information as
it shall deem appropriate at the time, continue to make its own credit
decisions in taking or not taking action under this Agreement; (C) such
assignee appoints and authorizes the Administrative Agent to take such action
as agent on its behalf and to exercise such powers and discretion under this
Agreement as are delegated to the Administrative Agent by the terms hereof,
together with such powers and discretion as are reasonably incidental thereto;
and (D) such assignee agrees that it will perform in accordance with their
terms all of the obligations that by the terms of this Agreement are required
to be performed by it as a Bank and agrees that shall be bound by all the terms
and provisions of this Agreement.

                (f)   The Administrative Agent shall maintain a copy of each
Assignment and Acceptance delivered to and accepted by it and a register for
the recordation of the names and addresses of the Banks and the Commitment of,
and principal amount of the Loans owing to, each Bank from time to time (the
"Register").  The entries in the Register shall be conclusive and binding for
all purposes, absent demonstrable error, and the Borrowers, the Administrative
Agent and the Banks may treat each Person whose name is recorded in the
Register as a Bank hereunder for all purposes of this Agreement.  The Register
shall be available for inspection by the Borrowers or any Bank at any
reasonable time and from time to time upon reasonable prior notice. 

                (g)   Upon its receipt of an Assignment and Acceptance executed 
by an assigning Bank and an assignee and, unless such assignment is of only a
portion of such assigning Bank's rights and obligations hereunder, the Notes
subject to such assignment, the Administrative Agent shall, if such Assignment
and Acceptance has been completed and the Administrative Agent and the
Borrowers have given their written consent under Section 11.6(d) (if required),
(i) accept such Assignment and Acceptance, (ii) record the information
contained therein in the Register and (iii) give prompt notice thereof to the
Borrowers.  Within five Business Days after its receipt of such notice, the
Borrowers, at their own expense, shall execute and deliver to the
Administrative Agent (in exchange for the surrendered Notes unless such
assignment is of only a portion of such assigning Bank's rights and 

                                       85
<PAGE>   93

obligations hereunder) new Revolving Note and Term Note to the order of such    
assignee and a new Bid-Option Note to the order of such assignee.  Such new
Notes shall be dated the effective date of such Assignment and Acceptance and
shall otherwise be in substantially the form of Exhibits A-1, A-2 and B-1
hereto, as applicable.

                (h)   If any Reference Bank makes an assignment of all of its
Commitment and Syndicated Loans to an unaffiliated institution  pursuant to
subsection (d) above, or if the Fixed Rate Loans of any Reference Bank are
repaid pursuant to Section 5.2 or 5.3, the Administrative Agent shall, with the
consent of the Required Banks and the Borrowers, appoint another Bank to act as
Reference Bank hereunder.  No assignee of any Bank shall be entitled to receive
any greater payment under Section 5.3 than such Bank would have been entitled
to receive with respect to the rights assigned or otherwise transferred, unless
such assignment is made by reason of the provisions of Section 5.2 or 5.3
requiring such Bank to designate a different lending office under certain
circumstances or at a time when the circumstances giving rise to such greater
payment did not exist.

                (i)   Each Bank may assign to one or more banks or other 
financial institutions any Bid-Option Note held by it.  Any such Bank
assigning a Bid-Option Note shall for all purposes of this Agreement be deemed
to be the holder of such Note, and no assignee under this Section 11.6(i) shall
as a result of such assignment become a "Bank" under this Agreement.

                (j)   Notwithstanding any other provision set forth in this
Agreement, any Bank may at any time create a security interest in, or assign,
all or any portion of its rights under this Agreement (including, without
limitation, the Loans owing to it and the Note or Notes held by it) in favor of
any Federal Reserve Bank in accordance with Regulation A of the Board of
Governors of the Federal Reserve System; provided that such creation of a
security interest or assignment shall not release such Bank from its
obligations under this Agreement.

        11.7    Confidentiality.  Each Bank agrees that all documentation and
other information made available by the Borrowers to such Bank under the terms
of this Agreement shall (except (a) to the extent required by legal or
governmental process or otherwise by law, or (b) if such documentation and
other information is publicly available or hereafter becomes publicly available
other than by action of such Bank, or was theretofore known to such Bank
independent of any disclosure thereto by the Borrowers, or (c) to the extent of
necessary disclosure to such Bank's accountants, attorneys or regulators, or
(d) in any litigation or similar proceedings related to this Agreement, the
Notes or any Letter of Credit) be held in the strictest confidence by such Bank
and disclosed only to those officers, employees and agents of such Bank or of
any Affiliate of such Bank involved in the administration of the credit from
time to time outstanding from such Bank to the Borrowers or otherwise involved
in servicing, maintaining or further developing the relationship between such
Bank and the Borrowers, each of which officers, employees and agents shall,
except as permitted under this Section 11.7 generally with respect to such
Bank, hold such documentation and other information in the strictest confidence
and to be used only in connection with this Agreement; provided that (i) such
Bank may disclose such documentation and other information, and all other

the Confidential Information Memorandum dated January, 1998 concerning
MascoTech) in connection with such Bank's credit evaluation of MascoTech and
its Subsidiaries, to any other financial institution to which such Bank sells
or proposes to sell a participation or other interest in any of its Loans
hereunder (or under any other credit agreement with the Borrowers), if such
other financial institution, prior to such disclosure, agrees for the benefit
of the Borrowers to comply with the provisions of this Section 11.7 (including
the provisions of this Section 11.7 allowing further disclosure to other
financial institutions to whom a sale of a participation or other interest is
proposed), or to any Federal Reserve Bank and (ii) such Bank may disclose the
provisions of this Agreement and the Notes and the amounts, maturities and
interest rates of its Loans and the amounts of Letters of Credit (and similar
information relating to any other credit agreement with the Borrowers) to any
purchaser or potential purchaser of any interest of such Bank in any Loan to
the Borrowers.

        11.8  Counterparts; Effectiveness of Telecopied Signatures.  This
Agreement may be executed in any number of counterparts, all of which taken
together shall constitute one and the same instrument and any of the parties
hereto may execute this Agreement by signing any such counterpart.  Delivery of
a telecopied signature on this Agreement shall be as effective against the
signer as delivery of its original signature.

        11.9  Table of Contents and Headings.  The table of contents and the
headings of the various subdivisions hereof are for the convenience of
reference only and shall in no way modify any of the terms or provisions
hereof.

        11.10 Construction of Certain Provisions.  If any provision of this
Agreement refers to any action to be taken by any Person, or which such Person
is prohibited from taking, such provision shall be applicable whether such
action is taken directly or indirectly by such Person, whether or not expressly
specified in such provision.

        11.11 Independence of Covenants.  All covenants hereunder shall be
given independent effect so that if a particular action or condition is not
permitted by any such covenant, the fact that it would be permitted by an
exception to, or would be otherwise within the limitations of, another covenant
shall not avoid the occurrence of a Default or any event or condition which
with notice or lapse of time, or both, could become such a Default if such
action is taken or such condition exists.

        11.12 Interest Rate Limitation.  Notwithstanding any provisions of this
Agreement or the Notes, in no event shall the amount of interest paid or agreed
to be paid by the Borrowers exceed an amount computed at the highest rate of
interest permissible under applicable law.  If, from any circumstances
whatsoever, fulfillment of any provision of this Agreement or the Notes at the
time performance of such provision shall be due, shall involve exceeding the
interest rate limitation validly prescribed by law which a court of competent
jurisdiction may deem applicable hereto, then, ipso facto, the obligations to
be fulfilled shall be reduced to an amount computed at the highest rate of
interest permissible under applicable law, and if for any reason whatsoever any
Bank shall ever receive as interest an amount which would be deemed unlawful
under such applicable law such interest shall be automatically applied to the
payment of principal of the Loans outstanding hereunder (whether or not 

                                       87
<PAGE>   95

then due and payable) and not to the payment of interest, or shall be
refunded to the Borrowers if such principal and all other obligations of the
Borrowers to the Banks have been paid in full.

        11.13   Substitution of Banks.

                (a)   After payment by the Borrowers to any Bank of any amount 
due pursuant to Section 5.3 or 5.5 that the Borrowers reasonably deem
material, and upon five Business Days' written notice in the form of Exhibit L
delivered to the Administrative Agent and the applicable Bank, the Borrowers
may replace any one or more of the Banks.  Upon the date of its effectiveness,
such notice shall terminate the Commitment of such Bank entirely, provided that
the Borrowers shall prepay each Loan of such Bank (if any) in full on the
effective date of such termination, together with accrued interest thereon, all
amounts due pursuant to Sections 5.3 and 5.5, all accrued facility fees with
respect to such Bank and all other amounts owing to such Bank hereunder to such
effective date. 


                (b)   If the Borrowers shall terminate the Commitment of any 
Bank pursuant to the provisions of subsection (a) of this Section 11.13, the
Borrowers shall designate another bank or other banks (which may be one of the
Banks) (in either case, an "Additional Bank") to be parties to this Agreement,
provided, that (i) without the consent of the Administrative Agent, the total
number of Additional Banks (other than those that were already Banks) may not
exceed the total number of Banks whose Commitments are terminated pursuant to
Section 11.13(a) plus six, (ii) the amount of the Commitment of any Additional
Bank may not be less than $10,000,000, (iii) the amount of the Commitment(s) of
the Additional Bank(s) (or, if any such Additional Bank already is a Bank, the
added portion of such Bank's Commitment) shall in the aggregate equal the
amount of the Commitment so terminated and (iv) the Borrowers or the Additional
Bank, and not the Bank being terminated pursuant to subsection (a) of this
Section 11.13, shall pay the processing and recordation fee required under
Section 11.6(d)(iv).  Any Additional Bank shall become a party to this
Agreement and be considered a Bank hereunder for all purposes if (i) it shall
agree in writing to be bound by all of the terms and provisions of this
Agreement, such agreement to specify the amount of the Commitment of such 
Additional Bank and to be otherwise in form and substance satisfactory to the
Administrative Agent, (ii) it shall make Syndicated Loans to the Borrowers in
principal amounts which bear the same ratio to the amounts of the Syndicated
Loans of other Banks (including other Additional Banks) then outstanding or to
be concurrently outstanding as the amount of the Commitment of such Additional
Bank bears to the then aggregate amount of the Commitments of such other Banks
(including other Additional Banks), and (iii) a copy of such agreement and of
evidence satisfactory to the Administrative Agent of the making of such Loans
shall be furnished to the Administrative Agent.  

        11.14   Governing Law.  This Agreement is a contract made under, and
shall be governed by and construed in accordance with, the law of the State of
New York applicable to contracts made and to be performed entirely within such
State and without giving effect to choice of law principles of such State. 

        11.15   Integration and Severability.  This Agreement and the Notes 
embody the entire agreement and understanding among the Borrowers, the
Administrative Agent, and the Banks, and 

                                       88
<PAGE>   96

supersede all prior agreements and understandings, relating to  the subject
matter hereof and thereof.  In case any one or more of the obligations of the
Borrowers under this Agreement or any Note shall be invalid, illegal or
unenforceable in any jurisdiction, the validity, legality and enforceability of
the remaining obligations of the Borrowers shall not in any way be affected or
impaired thereby, and such invalidity, illegality or unenforceability in one
jurisdiction shall not affect the validity, legality or enforceability of the
obligations of the Borrowers under this Agreement or any Note in any other
jurisdiction.

        11.16 WAIVER OF JURY TRIAL.  THE BANKS, THE ADMINISTRATIVE AGENT, THE
SYNDICATION AGENTS AND THE BORROWERS, AFTER CONSULTING OR HAVING HAD THE
OPPORTUNITY TO CONSULT WITH COUNSEL, KNOWINGLY, VOLUNTARILY AND INTENTIONALLY
WAIVE ANY RIGHT ANY OF THEM MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION BASED
UPON OR ARISING OUT OF THIS AGREEMENT OR ANY RELATED INSTRUMENT OR AGREEMENT OR
ANY OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR ANY COURSE OF
CONDUCT, DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF ANY OF
THEM RELATED HERETO OR THERETO.  NONE OF THE BANKS, THE ADMINISTRATIVE AGENT,
THE SYNDICATION AGENTS OR THE BORROWERS SHALL, TO THE EXTENT PERMITTED BY
APPLICABLE LAW, SEEK TO CONSOLIDATE, BY COUNTERCLAIM OR OTHERWISE, ANY SUCH
ACTION IN WHICH A JURY TRIAL HAS BEEN WAIVED WITH ANY OTHER ACTION IN WHICH A
JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED.

        11.17  Alternate Currency Addenda Binding on Each Bank; Provisions
Regarding Alternate Currency Agents.  Each of the Banks agrees that it shall be
bound by the provisions of each Alternate Currency Addendum entered into in
connection herewith, in particular as it relates to the provisions applicable
to the Alternate Currency Agent appointed thereunder.

        11.18  Unification of Certain Currencies.  If the Euro (or some other
similar unit of account) becomes a currency in its own right in connection with
European monetary union contemplated by the Maastricht Treaty, then each of the
Borrowers, the Banks and the Administrative Agent agrees to negotiate in good
faith an amendment to this Agreement satisfactory in form and substance to the
Borrowers, the Banks and the Administrative Agent to account therefor.  The
introduction of the Euro shall not have the effect of altering any term of any
Note or other instrument or discharging or excusing performance by any party
under any such Note or instrument or giving any party the right to terminate
any such Note or instrument.

<PAGE>   111

                (b)     Section 3.2 is amended in its entirety as follows:

                3.2     Term Loans.   Subject to the terms and conditions
        set forth in this Agreement, each Bank on and after the
        Closing Date severally and not jointly agrees to make a term
        loan, in Dollars, to one or more of the Borrowers in an
        aggregate amount not to exceed such Bank's Term Loan
        Commitment (each individually, a "Term Loan" and,
        collectively, the "Term Loans").  All Term Loans shall be
        made by the Banks on or after the Closing Date
        simultaneously and pro rata, it being understood that no
        Bank shall be responsible for any failure by any other Bank
        to perform its obligation to make any Term Loan hereunder
        nor shall the Term Loan Commitment of any Bank be increased
        or decreased as a result of any such failure, it being
        further understood that all or part of the initial Term
        Loans extended to the Borrowers on the Closing Date may be
        refinanced after the Closing Date with Term Loans made to
        one or more of the Borrowers.  Each Bank's Term Loan
        Commitment shall be reinstated as of the date any Borrower
        requests a Term Loan to refinance an existing Term Loan
        originally made to a different Borrower.

                (c)     Section 3.7(a) is amended to delete the word 
"Revolving" in the fifth line thereof.

                (d)     Section 3.8(b) is amended to add the following
sentence at the end thereof:

                Upon any refinancing of a Term Loan, the applicable
                Borrower or Borrowers shall execute a new Term Loan
                Note payable to each Bank in an amount equal to the
                Term Loan Commitment of such Bank.

                (e)     Section 3.10 is amended (1) to add "(a)" prior to
the first word thereof and (2) to add a new Section 3.10(b) as follows:

                Subject to Section 5.5, the Borrowers shall have the
        right at any time and from time to time, upon one Business
        Day's prior written notice to the Administrative Agent, to
        terminate or proportionately reduce the amount of the Term
        Loan Commitments, provided, that any partial reduction of
        the amount of the Term Loan Commitments shall be in the
        amount of $5,000,000 or a multiple of $1,000,000 in excess
        thereof, provided that after giving effect to any such
        voluntary reduction, the Dollar Equivalent of the
        outstanding Term Loans shall not exceed the amount of the
        Term Loan Commitments, as reduced from time to time.  The
        Term Loan Commitments or any portion thereof terminated or
        reduced pursuant to this Section may not be reinstated. 
        Upon receipt of any notice from the Borrowers pursuant to
        this Section, the Administrative Agent shall promptly notify
        each Bank of the contents thereof and of such Bank's share
        of any reduction of the Term Loan Commitments.  Each such
        notice shall be irrevocable by the Borrowers once the
        Administrative Agent begins notifying any Bank of the
        contents thereof.

Revolving Credit Commitments" in the first line and to substitute therefor 
"All Commitments" and (2) to delete the last sentence thereof.

                (g)     Section 4.1(b)(i) is amended (1) to add the words

thereto and (2) to add the following sentence after the word "hereunder" in 
the fourth line thereto:

        The principal amount of the installments may be paid by any or all
        of the Borrowers at their discretion provided that each of the quarterly
        installments shall be in the aggregate amounts set forth below:

                (h)     Section 4.1(b)(i) is further amended to insert the
words ", except that the initial Term Loans extended to the Borrowers on the

of the Borrowers" after the word "repaid" at the end thereof.

                (i)     The following Section 4.1(b)(ii) is added:

                A repayment made within five (5) Business Days prior to
        the scheduled installment date for such repayment, as set
        forth in Section 4.1(b)(i), shall be applied to the
        installment due within such five (5) Business Days and shall
        not be deemed a prepayment.  Any such repayment shall be
        subject to the provisions of Section 5.5.

                (j)     Section 4.2(g) is amended to add the words "(other
than repayments made within five (5) Business Days prior to the scheduled

                        CORPORATE SERVICES AGREEMENT


        This Agreement is made as of January 1, 1987 between Masco Corporation,
a Delaware corporation ("Masco"), and Masco Industries, Inc., a Delaware
corporation ("Industries").

        WHEREAS, Masco and Industries desire to amend and restate that certain
Corporate Services Agreement between them dated as of May 1, 1984 (the "1984
Corporate Services Agreement"); and

        WHEREAS, Masco and Industries desire to terminate that certain
Corporate Services Agreement dated as of July 1, 1985 (the "1985 Corporate
Services Agreement") between Masco's wholly-owned subsidiary Masco Building
Products Corp., a Delaware corporation ("MBPC"), and NI Industries, Inc. a
Delaware corporation and currently an indirect wholly-owned subsidiary of
Industries ("NI"); and

        WHEREAS, Industries desires that Masco provide, and Masco is willing to
provide, either directly or through its subsidiaries, certain services and
facilities on the terms and conditions hereinafter set forth; and

        WHEREAS, Masco desires that Industries provide, and Industries is
willing to provide, either directly or through NI, certain facilities on the
terms and conditions hereinafter set forth.

        NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained, the parties agree to amend and restate the 1984 Corporate
Services Agreement and take certain other action as follows:

<PAGE>   2

        1.   Masco shall provide to Industries and its subsidiaries corporate
support staff and administrative services of those personnel which Masco
maintains internally for its own officers, operating executives and business
operations and which Masco has heretofore provided to Industries' headquarters
and businesses pursuant to the 1984 Corporate Services Agreement, such as
accounting, legal, treasury, tax, corporate development, data processing,
research and development and human resources, provided that Masco shall not be
obligated to provide any services which would be in contravention of law. 
Masco shall furnish such services at the reasonable request of Industries,
provided that Masco shall not be required to disrupt the provisions of services
for its own business purposes and shall not be obligated to retain additional
employees in order to accommodate Industries' requirements for services other
than in the ordinary course of business.  In addition, Masco shall provide to
Industries headquarters office space and data processing equipment in Masco's
corporate office in Taylor, Michigan.

        2.   Industries shall provide to MBPC headquarters office space at the
corporate offices of NI in Long Beach, California, as heretofore provided
pursuant to the 1985 Corporate Services Agreement.

        3.   Industries will pay Masco a fee for the services and office space
provided under Section 1 hereof, irrespective of Industries' or its
subsidiaries' actual use thereof, equal to eight tenths of one percent of
Industries' consolidated annual net sales (pro rated for any partial year), as
shown in Industries' annual audited financial statements, less (in
consideration of the facilities provided by Industries to MBPC pursuant to
Section 2 hereof) the real estate related costs incurred by NI to maintain
headquarters office space for MBPC in NI's Long Beach, California headquarters,
including, but not limited to, depreciation expense, maintenance, repairs and
taxes related to such 

                                      2
<PAGE>   3

facility.  Such fee shall be payable monthly in arrears within 30 days of the
end of each month, based upon Industries' consolidated unaudited net sales for
each month, with such timely adjustment as may be required following the
preparation of such audited financial statements.  Industries shall be
responsible for the payment of fees and expenses for services rendered by
third parties retained by Masco on behalf of Industries and its subsidiaries. 
In addition, Industries shall pay for material utilized and purchased
components in research and development projects, in accordance with Masco's
customary practice.  The parties recognize that Industries may, in the future,
hire certain support and administrative staff to be employed solely by
Industries and incur other expenses for equipment, services or space, and to
the extent any such support and administrative staff are employed by
Industries or such expenses are incurred, Masco shall review the resulting
cost savings, if any, to Masco in providing support staff and administrative
services, equipment and headquarters office space hereunder and if, in Masco's
good faith judgment, such a cost savings has resulted, Masco shall reflect
such savings by a corresponding reduction in the subsequent fees to be paid
hereunder.

        4.   Additional services, facilities and other items made available by
Masco to its operating units which are not covered by the base fee will
similarly be made available to Industries except if the provision of such
services, facilities and other items would be in contravention of law.  The
charges for additional services, facilities and other items shall be determined
form time to time by Masco, but Industries shall have no obligation to purchase
or use any such additional services, facilities or other times.



                                      3
<PAGE>   4

        5.   The term of this agreement shall be from the date hereof through
December 31, 1988.  the term shall be extended automatically for a period of
one year each January 1 thereafter, provided that Masco may give notice of
non-renewal not less than 90 days prior to any such January 1.  This Agreement
may be terminated by Industries at any time, without cause, on 90 days written
notice, provided that such termination shall not relieve Industries of its
obligations accruing hereunder through the effective date of such termination.

        6.   In providing services, equipment and facilities hereunder, Masco
and Industries shall each have a duty to act, and to cause their respective
employees to act, in a reasonable and prudent manner.  Subject to the
provisions of the Research and Development Undertaking attached as Annex A
hereto, neither Masco or its subsidiaries, nor any officer, Director, employee
or agent of Masco or its subsidiaries, nor Industries or its subsidiaries, nor
any officer, director, employee or agent of Industries or its subsidiaries,
shall be liable for any loss incurred in connection with the matters to which
this Agreement relates, except a loss resulting from willful misfeasance or bad
faith.

        7.   The selection of Masco employees to provide services hereunder
shall be determined by Masco and such employees shall be the employees of
Masco.  All work performed hereunder by Masco shall be performed by Masco as an
independent contractor.

        8.   Masco and Industries shall take reasonable measures to keep
confidential all information concerning the other which is acquired in the
course of performing services hereunder and which is of a nature customarily
considered to be confidential by them.  Research and development services
provided by Masco shall be subject to the additional provisions set forth in
Annex A hereto.

                                      4
<PAGE>   5

        9.   This Agreement shall not be assigned by Industries without the
express written consent of Masco, except for an assignment by Industries to a
successor to substantially all of its business.

        10.  The 1985 Corporate Services Agreement is hereby terminated.

        IN WITNESS WHEREOF, the parties have executed this Agreement as of the
day and year first above written.

Gentlemen:

        As you are aware, MascoTech, Inc. completed its acquisition of TriMas
Corporation on Thursday, January 22, 1998 (the "Effective Date").  This will
confirm our agreement that the Corporate Services Agreement, dated as of
December 27, 1988, between Masco Corporation ("Masco") and TriMas Corporation
(the "TriMas Corporate Services Agreement"), is terminated effective as of the
end of business on the Effective Date, except with respect to rights and
obligations of the parties thereto which have accrued as a result of services
rendered thereunder prior to the Effective Date.  Furthermore, Masco agrees
that the period for which a fee is payable under the TriMas Corporate Services
Agreement will terminate on the earlier of (i) the Effective Date, or (ii) the
date immediately preceding the date that the consolidated net sales of TriMas
are included in the consolidated net sales of MascoTech, Inc.  After such date,
Masco will be compensated for work performed for the TriMas companies under
Masco's Corporate Services Agreement with MascoTech (the "MascoTech Corporate
Services Agreement").  Finally, Masco agrees that, in calculating the fee
payable under the MascoTech Corporate Services Agreement, MascoTech is entitled
to the credits that were historically permitted to TriMas under the TriMas
Corporate Services Agreement of up to $250,000 per year for occupancy costs at
TriMas' Ann Arbor headquarters (consisting of rent, utilities, maintenance and
property taxes), office supplies and postage costs at TriMas' Ann Arbor
headquarters and the credit historically provided for the Norris management
services that had been discontinued by you when Masco Building Products shut
down its operations.

        If the foregoing is your understanding of our Agreement, please
acknowledge by signing below on the attached copy of this letter, and returning
same to the undersigned.

                                   Very truly yours,

                                   MASCOTECH, INC.

SECTION 4.  SHARES AVAILABLE FOR AWARDS

        (a)  Shares Available.  Subject to adjustment as provided in Section
4(c):

            (i) Initial Authorization.  There shall be 8,000,000 Shares 
      initially available for issuance under the Plan.

            (ii) Acquired Shares.  In addition to the amount set forth above, up
      to 8,000,000 Shares acquired by the Company subsequent to the 1997 Annual
      Meeting of Stockholders as full or partial payment for the exercise price
      for an Option or any other stock option granted by the Company, or
      acquired by the Company, in open market transactions or otherwise, in
      connection with the Plan or any Award hereunder or any other employee
      stock option or restricted stock issued by the Company may thereafter be
      included in the Shares available for Awards.  If any Shares covered by an
      Award or to which an Award relates are forfeited, or if an Award expires,
      terminates or is cancelled, then the Shares covered by such Award, or to
      which such Award relates, or the number of Shares otherwise counted
      against the aggregate number of Shares available under the Plan by reason
      of such Award, to the extent of any such forfeiture, expiration,
      termination or cancellation, may thereafter be available for further
      granting of Awards and included as acquired Shares for purposes of the
      preceding sentence.

        
            (iii) Shares Under Prior Plans.  In addition to the amounts set 
      forth above, shares remaining available for issuance upon any termination
      of authority to make further awards under both the Company's 1988
      Restricted Stock Incentive Plan and its 1988 Stock Option Plan shall
      thereafter be available for issuance hereunder.
        
            (iv) Accounting for Awards.  For purposes of this Section 4, 

                                         3
<PAGE>   4

                  (A) if an Award (other than a Dividend Equivalent) is
            denominated in Shares, the number of Shares covered by such Award,
            or to which such Award relates, shall be counted on the date of
            grant of such Award against the aggregate number of Shares
            available for granting Awards under the Plan to the extent
            determinable on such date and insofar as the number of Shares is
            not then determinable under procedures adopted by the Committee
            consistent with the purposes of the Plan; and
        
                  (B) Dividend Equivalents and Awards not denominated in Shares
            shall be counted against the aggregate number of Shares available 
            for granting Awards under the Plan in such amount and at such time
            as the Committee shall determine under procedures adopted by the 
            Committee consistent with the purposes of the Plan;

      provided, however, that Awards that operate in tandem with (whether
      granted simultaneously with or at a different time from), or that are
      substituted for, other Awards or restricted stock awards or stock options
      granted under any other plan of the Company may be counted or not counted
      under procedures adopted by the Committee in order to avoid double
      counting. Any Shares that are delivered by the Company or its Affiliates,
      and any Awards that are granted by, or become obligations of, the
      Company, through the assumption by the Company of, or in substitution
      for, outstanding restricted stock awards or stock options previously
      granted by an acquired company shall not, except in the case of Awards
      granted to Participants who are directors or officers of the Company for
      purposes of Section 16, be counted against the Shares available for
      granting Awards under the Plan.
        
            (v) Sources of Shares Deliverable Under Awards.  Any Shares 
      delivered pursuant to an Award may consist, in whole or in part, of
      authorized but unissued Shares or of Shares reacquired by the Company,
      including but not limited to Shares purchased on the open market.
        
        (b) Individual Stock-Based Awards.  Subject to adjustment as provided
in Section 4(c), no Participant may receive Options or Stock Appreciation
Rights under the Plan in any calendar year that relate to more than 1,000,000
Shares in the aggregate; provided, however, that such number may be increased
with respect to any Participant by any Shares available for grant to such
Participant in accordance with this Paragraph 4(b) in any prior years that were
not granted in such prior year beginning on or after January 1, 1997. No
provision of this Paragraph 4(b) shall be construed as limiting the amount of
any other stock-based or cash-based Award which may be granted to any
Participant.    

        (c)  Adjustments.  Upon the occurrence of any dividend or other 
distribution (whether in the form of cash, Shares, other securities or other
property), change in the capital or shares of capital stock, recapitalization,
stock split, reverse stock split, reorganization, merger, consolidation,
split-up, spin-off, combination, repurchase, or exchange of Shares or other
securities of the Company, issuance of warrants or other rights to purchase
Shares or other securities of the Company or extraordinary transaction or event
which affects the Shares, then the Committee shall have the authority to make
such adjustment, if any, in such manner as it deems appropriate, in (i) the
number and type of Shares (or other securities or property) which thereafter
may be made the subject of Awards, (ii) outstanding Awards including without
limitation the number and type of Shares (or other securities or property)
subject thereto, and (iii) the grant, purchase or exercise price with respect
to outstanding Awards and, if deemed appropriate, make provision for cash
payments to the holders of outstanding Awards; provided, however,  that the
number of Shares subject to any Award denominated in Shares shall always be a
whole number.

SECTION 5.  ELIGIBILITY

        Any employee of or consultant to the Company or any Affiliate,
including any officer of the Company (who may also be a director,  any person
who serves only as a director of the Company and any consultant to the Company
or an Affiliate who is also a director of the Company and who is not rendering
services pursuant to a written agreement with the entity in question), as may
be selected from time to time by the Committee or by the directors to whom

authority may be delegated pursuant to Section 3 hereof in its or their
discretion, is eligible to be designated a Participant.

SECTION 6.  AWARDS

        (a)  Options.  The Committee is authorized to grant Options to 
Participants.

            (i) Committee Determinations.  Subject to the terms of the Plan, the
      Committee shall determine:

                  (A) the purchase price per Share under each Option, provided,
            however, that such price shall be not less than 100% of the fair
            market value of the Shares underlying such Option on the date of
            grant;

                  (B) the term of each Option; and

                  (C) the time or times at which an Option may be exercised, in
            whole or in part, the method or methods by which and the form or 
            forms (including, without limitation, cash, Shares, other
            Awards or other property, or any combination thereof, having a fair
            market value on the exercise date equal to the relevant exercise
            price) in which payment of the exercise price with respect thereto
            may be made or deemed to have been made. The terms of any Incentive
            Stock Option granted under the Plan shall comply in all respects
            with the provisions of Section 422 of the Code, or any successor
            provision thereto, and any regulations promulgated thereunder.
        
      Subject to the terms of the Plan, the Committee may impose such conditions
      or restrictions on any Option as it deems appropriate.

            (ii) Other Terms.  Unless otherwise determined by the Committee:

                  (A) A Participant electing to exercise an Option shall give
            written notice to the Company, as may be specified by the Committee,
            of exercise of the Option and the number of Shares elected for ex-
            ercise, such notice to be accompanied by such instruments or 
            documents as may be required by the Committee, and shall tender the
            purchase price of the Shares elected for exercise.

                  (B) At the time of exercise of an Option payment in full in 
            cash or in Shares (that have been held by the Participant for at
            least six months) or any combination thereof, at the option of the
            Participant, shall be made for all Shares then being purchased.
        
                  (C) The Company shall not be obligated to issue any Shares
            unless and until:

                       (I) if the class of Shares at the time is listed upon any
                  stock exchange, the Shares to be issued have been listed, or
                  authorized to be added to the list upon official notice of 
                  issuance, upon such exchange, and

                       (II) in the opinion of the Company's counsel there has 
                  been compliance with applicable law in connection with the 
                  issuance and delivery of Shares and such issuance shall have
                  been approved by the Company's counsel.
                  

                  Without limiting the generality of the foregoing, the Company
            may require from the Participant such investment representation or
            such agreement, if any, as the Company's counsel may consider
            necessary in order to comply with the Securities Act of 1933 as then
            in effect, and may require that the Participant agree that any sale
            of the Shares will be made only in such manner as shall 




                                      5

<PAGE>   6
            be in accordance with law and that the Participant will notify the
            Company of any intent to make any disposition of the Shares whether
            by sale, gift or otherwise. The Participant shall take any action
            reasonably requested by the Company in such connection. A 
            Participant shall have the rights of a stockholder only as and when
            Shares have been actually issued to the Participant pursuant to the
            Plan.

                  (D) If the employment of or consulting arrangement with a
            Participant terminates for any reason (including termination by
            reason of the fact that an entity is no longer an Affiliate) other
            than the Participant's death, the Participant may thereafter
            exercise the Option as provided below, except that the Committee
            may terminate the unexercised portion of the Option concurrently
            with or at any time following termination of the employment or
            consulting arrangement (including termination of employment upon a
            change of status from employee to consultant) if it shall determine
            that the Participant has engaged in any activity detrimental to the
            interests of the Company or an Affiliate. If such termination is
            voluntary on the part of the Participant, the Option may be
            exercised only within ten days after the date of termination. If
            such termination is involuntary on the part of the Participant, if
            an employee retires on or after normal retirement date or if the
            employment or consulting relationship is terminated by reason of
            permanent and total disability, the Option may be exercised within
            three months after the date of termination or retirement. For
            purposes of this Paragraph (D), a Participant's employment or
            consulting arrangement shall not be considered ter- minated (i) in
            the case of approved sick leave or other bona fide leave of absence
            (not to exceed one year), (ii) in the case of a transfer of
            employment or the consulting arrangement among the Company and
            Affiliates, or (iii) by virtue of a change of status from employee
            to consultant or from consultant to employee, except as provided
            above.
        
                  (E) If a Participant dies at a time when entitled to exercise
            an Option, then at any time or times within one year after death
            such Option may be exercised, as to all or any of the Shares which
            the Participant was entitled to purchase immediately prior to
            death.  The Company may decline to deliver Shares to a designated
            beneficiary until it receives indemnity against claims of third
            parties satisfac- tory to the Company. Except as so exercised such
            Option shall expire at the end of such period.
        
                  (F) An Option may be exercised only if and to the extent such
            Option was exercisable at the date of termination of employment or
            the consulting arrangement, and an Option may not be exercised at 
            a time when the Option would not have been exercisable had the 
            employment or consulting arrangement continued.

            (iii) Restoration Options.  The Committee may grant a Participant 
      the right to receive a restoration Option with respect to an Option or
      any other stock option granted by the Company.  Unless the Committee
      shall otherwise determine, a restoration Option shall provide that the
      underlying option must be exercised while the Participant is an employee
      of or consultant to the Company or an Affiliate and the number of Shares
      which are subject to a restoration Option shall not exceed the number of
      whole Shares exchanged in payment for the exercise of the original
      option.
        
        (b)  Stock Appreciation Rights.  The Committee is authorized to grant 
Stock Appreciation Rights to Participants. Subject to the terms of the Plan, a
Stock Appreciation Right granted under the Plan shall confer on the holder
thereof a right to receive, upon exercise thereof, the excess of (i) the fair
market value of one Share on the date of exercise or, if the Committee shall so
determine in the case of any such right other than one related to any Incentive
Stock Option, at any time during a specified period before or after the date of
exercise over (ii) the grant price of the right as specified by the Committee.
Subject to the terms of the Plan, the Committee shall determine the grant
price, term, methods of exercise and settlement and any other terms and
conditions of any Stock Appreciation Right and may impose such conditions or
restrictions on the exercise of any Stock Appreciation Right as it may deem
appropriate.

      (c)  Restricted Stock and Restricted Stock Units.

            (i) Issuance.  The Committee is authorized to grant to Participants
      Awards of Restricted Stock, which shall consist of Shares, and Restricted
      Stock Units which shall give the Participant the right to receive cash,
      other securities, other Awards or other property, in each case subject to
      the termination of the Restricted Period determined by the Committee.

            (ii) Restrictions.  The Restricted Period may differ among
      Participants and may have different expiration dates with respect to
      portions of Shares covered by the same Award.  Subject to the terms of the
      Plan, Awards of Restricted Stock and Restricted Stock Units shall have 
      such restrictions as the Committee may impose (including, without
      limitation, limitations on the right to vote Restricted Stock or the
      right to receive any dividend or other right or property), which
      restrictions may lapse separately or in combination at such time or
      times, in installments or otherwise. Unless the Committee shall otherwise
      determine, any Shares or other securities distributed with respect to
      Restricted Stock or which a Participant is otherwise entitled to receive
      by reason of such Shares shall be subject to the restrictions contained
      in the applicable Award Agreement. Subject to the aforementioned
      restrictions and the provisions of the Plan, Participants shall have all
      of the rights of a stockholder with respect to Shares of Restricted
      Stock.
        
            (iii) Registration.  Restricted Stock granted under the Plan may be
      evidenced in such manner as the Committee may deem appropriate, including,
      without limitation, book-entry registration or issuance of stock certifi-
      cates.

            (iv) Forfeiture.  Except as otherwise determined by the Committee:

                  (A) If the employment of or consulting arrangement with a
            Participant terminates for any reason (including termination by
            reason of the fact that any entity is no longer an Affiliate),
            other than the Participant's death or permanent and total
            disability or, in the case of an employee, retirement on or after
            normal retirement date, all Shares of Restricted Stock theretofore
            awarded to the Participant which are still subject to restrictions
            shall upon such termination of employment or the consulting
            relationship be forfeited and transferred back to the Company.
            Notwithstanding the foregoing or Paragraph (C) below, if a
            Participant continues to hold an Award of Restricted Stock
            following termination of the employment or consulting arrangement
            (including retirement and termination of employment upon a change
            of status from employee to consultant), the Shares of Restricted
            Stock which remain subject to restrictions shall nonetheless be
            forfeited and transferred back to the Company if the Committee at
            any time thereafter determines that the Participant has engaged in
            any activity detrimental to the interests of the Company or an
            Affiliate. For purposes of this Paragraph (A), a Participant's
            employment or consulting arrangement shall not be considered
            terminated (i) in the case of approved sick leave or other bona
            fide leave of absence (not to exceed one year), (ii) in the case of
            a transfer of employment or the consulting arrangement among the
            Company and Affiliates, or (iii) by virtue of a change of status
            from employee to consultant or from consultant to employee, except
            as provided above.

                  (B) If a Participant ceases to be employed or retained by the
            Company or an Affiliate by reason of death or permanent and total
            disability or if following retirement a Participant continues to 
            have rights under an Award of Restricted Stock and thereafter dies,
            the restrictions contained in the Award shall lapse with respect to
            such Restricted Stock.
        
                  (C) If an employee ceases to be employed by the Company or an
            Affiliate by reason of retirement on or after normal retirement 
            date, the restrictions contained in the Award of Restricted Stock 
            shall continue to lapse in the same manner as though employment had
            not terminated.

                  (D) At the expiration of the Restricted Period as to Shares
            covered by an Award of Restricted Stock, the Company shall deliver
            the Shares as to which the Restricted Period has expired, as 
            follows:

                       (1) if an assignment to a trust has been made in 
                  accordance with Section 6(g)(iv)(B)(2)(c), to such trust; or

                       (2) if the Restricted Period has expired by reason of 
                  death and a beneficiary has been designated in form approved
                  by the Company, to the beneficiary so designated; or

                       (3) in all other cases, to the Participant or the legal
                  representative of the Participant's estate.

        (d)  Performance Awards.  The Committee is authorized to grant
Performance Awards to Participants. Subject to the terms of the Plan, a
Performance Award granted under the Plan (i) may be denominated or payable in
cash, Shares (including, without limitation, Restricted Stock), other
securities, other Awards, or other property and (ii) shall confer on the holder
thereof rights valued as determined by the Committee and payable to, or
exercisable by, the holder of the Performance Award, in whole or in part, upon
the achievement of such performance goals during such performance periods as
the Committee shall establish. Subject to the terms of the Plan, the
performance goals to be achieved during any performance period, the length of
any performance period, the amount of any Performance Award granted, the amount
of any payment or transfer to be made pursuant to any Performance Award and
other terms and conditions shall be determined by the Committee.

        (e)  Dividend Equivalents.  The Committee is authorized to grant to
Participants Awards under which the holders thereof shall be entitled to
receive payments equivalent to dividends or interest with respect to a number
of Shares determined by the Committee, and the Committee may provide that such
amounts (if any) shall be deemed to have been reinvested in additional Shares
or otherwise reinvested. Subject to the terms of the Plan, such Awards may have
such terms  and conditions as the Committee shall determine.

        (f)  Other Stock-Based Awards.  The Committee is authorized to grant to
Participants such other Awards that are denominated or payable in, valued in
whole or in part by reference to or otherwise based on or related to Shares
(including, without limitation, securities convertible into Shares), as are
deemed by the Committee to be consistent with the purposes of the Plan,
provided, however, that such grants to persons who are subject to Section 16
must comply with the provisions of Rule 16b-3. Subject to the terms of the
Plan, the Committee shall determine the terms and conditions of such Awards.
Shares or other securities delivered pursuant to a purchase right granted under
this Section 6(f) shall be purchased for such consideration, which may be paid
by such method or methods and in such form or forms, including, without
limitation, cash, Shares, other securities, other Awards or other property or
any combination thereof, as the Committee shall determine.

      (g)  General.

            (i) No Cash Consideration for Awards.  Awards may be granted for no
      cash consideration or for such minimal cash consideration as may be 
      required by applicable law.

            (ii) Awards May Be Granted Separately or Together.  Awards may, in
      the discretion of the Committee, be granted either alone or in addition
      to, in tandem with or in substitution for any other Award or any award
      granted un- der any other plan of the Company or any Affiliate. Awards
      granted in addition to or in tandem with other Awards or in addition to
      or in tandem with awards granted under another plan of the Company or any
      Affiliate, may be granted either at the same time as or at a different
      time from the grant of such other Awards or awards.

            (iii) Forms of Payment Under Awards.  Subject to the terms of the 
      Plan and of any applicable Award Agreement, payments or transfers to be
      made by the Company or an Affiliate upon the grant, exercise, or payment
      of an Award may be made in such form or forms as the Committee shall
      determine, including, without limitation, cash, Shares, other securities,
      other Awards, or other property, or any combination thereof, and may be
      made in a single payment or transfer, in installments, or on a deferred
      basis, in each case in accordance with rules and procedures established
      by the Committee. Such rules and procedures may include, without
      limitation, provisions for the payment or crediting of reasonable
      interest on installment or deferred payments or the grant or crediting of
      Dividend Equivalents in respect of installment or deferred payments.
        
            (iv) Limits on Transfer of Awards.

                  (A) Except as the Committee may otherwise determine, no Award
            or right under any Award may be sold, encumbered, pledged, 
            alienated, attached, assigned or transferred in any manner and any
            attempt to do any of the foregoing shall be void and unenforceable
            against the Company.

                  (B) Notwithstanding the provisions of Paragraph (A) above:

                       (1) An Option may be transferred:

                             (a) to a beneficiary designated by the Participant
                        in writing on a form approved by the Committee; 

                             (b) by will or the applicable laws of descent and
                        distribution to the personal representative, executor or
                        administrator of the Participant's estate; or

                              (c) to a revocable grantor trust established by 
                        the Participant for the sole benefit of the Participant
                        during the Participant's life, and under the terms of 
                        which the Participant is and remains the sole trustee 
                        until death or physical or mental incapacity. Such 
                        assignment shall be effected by a written instrument 
                        in form and content satisfactory to the Committee, and 
                        the Participant shall deliver to the Committee a true 
                        copy of the agreement or other document evidencing such
                        trust. If in the judgment of the Committee the trust 
                        to which a Participant may attempt to assign rights 
                        under such an Award does not meet the criteria of a 
                        trust to which an assignment is permitted by the terms
                        hereof, or if after assignment, because of amendment, 
                        by force of law or any other reason such trust no 
                        longer meets such criteria, such attempted assignment 
                        shall be void and may be disregarded by the Committee 
                        and the Company and all rights to any such Options 
                        shall revert to and remain solely in the Participant. 
                        Notwithstanding a qualified assignment, the
                        Participant, and not the trust to which rights under
                        such an Option may be as signed, for the purpose of
                        determining compensation arising by reason of the
                        Option shall continue to be considered an employee or
                        consultant, as the case may be, of the Company or an
                        Affiliate, but such trust and the Participant shall be
                        bound by all of the terms and conditions of the Award
                        Agreement and this Plan. Shares issued in the name of
                        and delivered to such trust shall be conclusively   
                        considered issuance and delivery to the Participant.
        
                        (2) A Participant may assign or transfer rights under an
                  Award of Restricted Stock or Restricted Stock Units:

                             (a) to a beneficiary designated by the Participant
                        in writing on a form approved by the Committee;




                                      9
<PAGE>   10



                             (b) by will or the applicable laws of descent and
                        distribution to the personal representative, executor or
                        administrator of the Participant's estate; or

                              (c) to a revocable grantor trust established by 
                        the Participant for the sole benefit of the Participant
                        during the Participant's life, and under the terms of
                        which the Participant is and remains the sole trustee
                        until death or physical or mental incapacity. Such
                        assignment shall be effected by a written instrument in
                        form and content satisfactory to the Committee, and the
                        Participant shall deliver to the Committee a true copy
                        of the agreement or other document evidencing such
                        trust. If in the judgment of the Committee the trust to
                        which a Participant may attempt to assign rights
                        under such an Award does not meet the criteria of a
                        trust to which an assignment is permitted by the terms
                        hereof, or if after assignment, because of amendment,
                        by force of law or any other reason such trust no
                        longer meets such criteria, such attempted assignment
                        shall be void and may be disregarded by the Committee
                        and the Company and all rights to any such Awards shall
                        revert to and remain solely in the Participant.
                        Notwithstanding a qualified assignment, the
                        Participant, and not the trust to which rights under
                        such an Award may be assigned, for the purpose of
                        determining compensation arising by reason of the Award
                        shall continue to be considered an employee or
                        consultant, as the case may be, of the Company or an
                        Affiliate, but such trust and the Participant shall be
                        bound by all of the terms and conditions of the Award
                        Agreement and this Plan. Shares issued in the name of
                        and delivered to such trust shall be conclusively
                        considered issuance and delivery to the Participant.
        
                        (3) The Committee shall not permit directors or officers
                  of the Company for purposes of Section 16 to transfer or 
                  assign Awards except as permitted under Rule 16b-3.

                  (C) The Committee, the Company and its officers, agents and
            employees may rely upon any beneficiary designation, assignment or
            other instrument of transfer, copies of trust agreements and any
            other documents delivered to them by or on behalf of the
            Participant which they believe genuine and any action taken by them
            in reliance thereon shall be conclusive and binding upon the
            Participant, the personal representatives of the Participant's
            estate and all persons asserting a claim based on an Award. The
            delivery by a Participant of a beneficiary designation, or an
            assignment of rights under an Award as permitted hereunder, shall
            constitute the Participant's irrevocable undertaking to hold the
            Committee, the Company and its officers, agents and employees
            harmless against claims, including any cost or expense incurred in
            defending against claims, of any person (including the Participant)
            which may be asserted or alleged to be based on an Award subject to
            a beneficiary  designation or an assignment. In addition, the
            Company may decline to deliver Shares to a beneficiary until it
            receives indemnity  against claims of third parties satisfactory to
            the Company.
        
            (v) Share Certificates.  All certificates for Shares or other
      securities delivered under the Plan pursuant to any Award or the exercise
      thereof shall be subject to such stop transfer orders and other
      restrictions as the Committee may deem advisable under the Plan or the
      rules, regulations and other requirements of the Securities and Exchange
      Commission, any stock exchange upon which such Shares or other securities
      are then listed and any applicable Federal or state securities laws, and
      the Committee may cause a legend or legends to be put on any such
      certificates to make appropriate reference to such restrictions.
        
            (vi) Change in Control.  (A) Notwithstanding any of the provisions
      of this Plan or instruments evidencing Awards granted hereunder, upon a
      Change in Control of the Company (as hereinafter defined) the vesting of
      all rights of Participants under outstanding Awards shall be accelerated
      and all restrictions thereon shall terminate in order that Participants
      may fully realize the benefits thereunder. Such acceleration shall 




                                     10
<PAGE>   11



      include, without limitation, the immediate exercisability in full of all
      Options and the termination of restrictions on Restricted Stock and
      Restricted Stock Units. Further, in addition to the Committee's authority
      set forth in Section 4(c), the Committee, as constituted before such
      Change in Control, is authorized, and has sole discretion, as to any
      Award, either at the time such Award is made hereunder or any time
      thereafter, to take any one or more of the following actions: (i) provide
      for the purchase of any such Award, upon the Participant's request, for
      an amount of cash equal to the amount that could have been attained upon
      the exercise of such Award or realization of the Participant's rights had
      such Award been currently exercisable or payable; (ii) make such
      adjustment to any such Award then outstanding as the Committee deems
      appropriate to reflect such Change in Control; and (iii) cause any such
      Award then outstanding to be assumed, or new rights substituted
      therefor, by the acquiring or surviving corporation after such Change in
      Control.
        
            (B)   With respect to any Award granted hereunder prior to December
      6, 1995, a Change in Control shall occur if:

                  (1) any "person" or "group of persons" as such terms are used
            in Sections 13(d) and 14(d) of the Exchange Act, other than
            pursuant to a transaction or agreement previously approved by the
            Board of Directors of the Company, directly or indirectly purchases
            or otherwise becomes the "beneficial owner" (as defined in Rule
            13d-3 under the Exchange Act) or has the right to acquire such
            beneficial ownership (whether or not such right is exercisable
            immediately, with the passage of time, or subject to any condition)
            of voting securities representing 25 percent or more of the
            combined voting power of all outstanding voting securities of the
            Company; or
        
                  (2) during any period of twenty-four consecutive calendar
            months, the individuals who at the beginning of such period 
            constitute the Company's Board of Directors, and any new directors
            whose election by such Board or nomination for election by
            stockholders was approved by a vote of at least two-thirds of the
            members of such Board who were either directors on such Board at
            the beginning of the period or whose election or nomination for
            election as directors was previously so approved, for any reason
            cease to constitute at least a majority of the members thereof.
        
            (C)   Notwithstanding the provisions of subparagraph (B), with 
      respect to Awards granted hereunder on or after December 6, 1995, a
      Change in Control shall occur only if the event described in this
      subparagraph (C) shall have occurred.  With respect to any other Award
      granted prior thereto, a Change in Control shall occur if any of the
      events described in subparagraphs (B) or (C) shall have occurred, unless
      the holder of any such Award shall have consented to the application of
      this subparagraph (C) in lieu of the foregoing subparagraph (B).  A
      Change in Control for purposes of this subparagraph (C) shall occur if,
      during any period of twenty-four consecutive calendar months, the
      individuals who at the beginning of such period  constitute the Company's
      Board of Directors, and any new directors (other than Excluded Directors,
      as hereinafter defined), whose election by such Board or nomination for
      election by stockholders was approved by a vote of at least two-thirds of
      the members of such Board who were either directors on such Board at the
      beginning of the period or whose election or nomination for election as
      directors was previously so approved, for any reason cease to constitute
      at least a majority of the members thereof.  For purposes hereof,
      "Excluded Directors" are directors whose election by the Board or
      approval by the Board for stockholder election occurred within one year
      of any "person" or "group of persons", as such terms are used in Sections
      13(d) and 14(d) of the Exchange Act, commencing a tender offer for, or
      becoming the beneficial owner of, voting securities representing 25
      percent or more of the combined voting power of all outstanding voting
      securities of the Company, other than pursuant to a tender offer approved
      by the Board prior to its commencement or pursuant to stock acquisitions
      approved by the Board prior to their representing 25 percent or more of
      such combined voting power.
        
            (D) (1)     In the event that subsequent to a Change in Control it
      is determined that any payment or distribution by the Company to or for 
      the benefit of a Participant, whether paid or payable or distributed or




                                     11

<PAGE>   12
      distributable pursuant to the terms of this Plan or otherwise, other than
      any payment pursuant to this subparagraph (D) (a "Payment"), would be
      subject to the excise tax imposed by Section 4999 of the Code or any
      interest or penalties with respect to such excise tax (such excise tax,
      together with any such interest and penalties, are hereinafter 
      collectively referred to as the "Excise Tax"), then such Participant
      shall be entitled to receive from the Company, within 15 days following
      the determination described in (2) below, an additional payment ("Excise
      Tax Adjustment Payment") in an amount such that after payment by such
      Participant of all applicable Federal, state and local taxes (computed at
      the maximum marginal rates and including any interest or penalties
      imposed with respect to such taxes), including any Excise Tax, imposed
      upon the Excise Tax Adjustment Payment, such Participant retains an
      amount of the Excise Tax Adjustment Payment equal to the Excise Tax
      imposed upon the Payments.
        
            (2)   All determinations required to be made under this Section
      6(g)(vi)(D), including whether an Excise Tax Adjustment Payment is 
      required and the amount of such Excise Tax Adjustment Payment, shall be
      made by Coopers & Lybrand L.L.P., or such other national accounting firm
      as the Company, or, subsequent to a Change in Control, the Company and
      the Participant jointly, may designate, for purposes of the Excise Tax,
      which shall provide detailed supporting calculations to the Company and
      the affected Participant within 15 business days of the date of the
      applicable Payment.  Except as hereinafter provided, any determination by
      Coopers & Lybrand L.L.P., or such other national accounting firm, shall
      be binding upon the Company and the Participant.  As a result of the
      uncertainty in the application of Section 4999 of the Code that may exist
      at the time of the initial determination hereunder, it is possible that
      (x) certain Excise Tax Adjustment Payments will not have been made by the
      Company which should have been made (an "Underpayment"), or (y) certain
      Excise Tax Adjustment Payments will have been made which should not have
      been made (an "Overpayment"), consistent with the calculations required
      to be made hereunder.  In the event of an Underpayment, such Underpayment
      shall be promptly paid by the Company to or for the benefit of the
      affected Participant.  In the event that the Participant discovers that
      an Overpayment shall have occurred, the amount thereof shall be promptly
      repaid to the Company.
        
            (3)   This Section 6(g)(vi)(D) shall not apply to any Award (x) that
      was granted prior to February 17, 1993 and (y) the holder of which is an
      executive officer of the Company, as determined under the Exchange Act.

            (vii)  Cash Settlement.  Notwithstanding any provision of this Plan
      or of any Award Agreement to the contrary, any Award outstanding 
      hereunder may at any time be cancelled in the Committee's sole discretion
      upon payment of the value of such Award to the holder thereof in cash or
      in another Award hereunder, such value to be determined by the Committee
      in its sole discretion.

SECTION 7.  AMENDMENT AND TERMINATION

        Except to the extent prohibited by applicable law and unless otherwise
expressly provided in an Award Agreement or in the Plan:

        (a)  Amendments to the Plan.  The Board of Directors of the Company may
amend the Plan and the Board of Directors or the Committee may amend any out-
standing Award; provided, however,  that (i) no Plan amendment shall be
effective until approved by stockholders of the Company insofar as stockholder
approval thereof is required in order for the Plan to continue to satisfy the
conditions of Rule 16b-3, and (ii) without the consent of affected Participants
no amendment of the Plan or of any Award may impair the rights of Participants
under outstanding Awards, and (iii) no Option may be amended to reduce its
initial exercise price other than in connection with an event described in
Section 4(c) hereof.

        (b)  Waivers.  The Committee may waive any conditions or rights under
any Award theretofore granted, prospectively or retroactively, without the
consent of any Participant.



                                     12

<PAGE>   13
        (c)  Adjustments of Awards Upon the Occurrence of Certain Unusual or
Nonrecurring Events.  The Committee shall be authorized to make adjustments in
the terms and conditions of, and the criteria included in, Awards in
recognition of unusual or nonrecurring events (including, without limitation,
the events described in Section 4(c) hereof) affecting the Company, any
Affiliate, or the financial statements of the Company or any Affiliate, or of
changes in applicable laws, regulations, or accounting principles, whenever the
Committee determines that such adjustments are appropriate in order to prevent
dilution or enlargement of the benefits or potential benefits to be made
available under the Plan.

        (d)  Correction of Defects, Omissions, and Inconsistencies.  The
Committee may correct any defect, supply any omission or reconcile any
inconsistency in the Plan or any Award in the manner and to the extent it shall
deem desirable to effectuate the Plan. 

SECTION 8.  GENERAL PROVISIONS

        (a)  No Rights to Awards.  No Participant or other person shall have
any claim to be granted any Award under the Plan, and there is no obligation
for uni- formity of treatment of Participants or holders or beneficiaries of
Awards under the Plan. The terms and conditions of Awards of the same type and
the determination of the Committee to grant a waiver or modification of any
Award and the terms and conditions thereof need not be the same with respect to
each Participant.

        (b)  Withholding.  The Company or any Affiliate shall be authorized to
withhold from any Award granted or any payment due or transfer made under any
Award or under the Plan the amount (in cash, Shares, other securities, other
Awards or other property) of withholding taxes due in respect of an Award, its
exercise or any payment or transfer under such Award or under the Plan and to
take such other action as may be necessary in the opinion of the Company or
Affiliate to satisfy all obligations for the payment of such taxes.

        (c)  No Limit on Other Compensation Arrangements.  Nothing contained in
the Plan shall prevent the Company or any Affiliate from adopting or continuing
in effect other or additional compensation arrangements, including the grant of
op- tions and other stock-based awards, and such arrangements may be either
generally applicable or applicable only in specific cases.

        (d)  No Right to Employment.  The grant of an Award shall not be
construed as giving a Participant the right to be retained in the employ of the
Company or any Affiliate. Further, the Company or an Affiliate may at any time
dismiss a Participant from employment, free from any liability, or any claim
under the Plan, unless otherwise expressly provided in the Plan or in any Award
Agreement or other written agreement with the Participant.

        (e)  Governing Law.  The validity, construction and effect of the Plan
and any rules and regulations relating to the Plan shall be determined in
accordance with the laws of the State of Michigan and applicable Federal law.

        (f)  Severability.  If any provision of the Plan or any Award is or
becomes or is deemed to be invalid, illegal or unenforceable in any
jurisdiction or as to any person or Award, or would disqualify the Plan or any
Award under any law deemed applicable by the Committee, such provision shall be
construed or deemed amended to conform to applicable laws, or if it cannot be
so construed or deemed amended without, in the determination of the Committee,
materially altering the intent of the Plan or the Award, such provision shall
be stricken as to such jurisdiction, person or Award, and the remainder of the
Plan and any such Award shall remain in full force and effect.

        (g)  No Trust or Fund Created.  Neither the Plan nor any Award shall
create or be construed to create a trust or separate fund of any kind or a
fiduciary relationship between the Company or any Affiliate and a Participant
or any other person. To the extent that any person acquires a right to receive
payments from the Company or any Affiliate pursuant to an Award, such right
shall be no greater than the right of any unsecured general creditor of the
Company or any Affiliate.




                                     13

        (h)  No Fractional Shares.  No fractional Shares shall be issued or
delivered pursuant to the Plan or any Award, and the Committee shall determine
whether cash, other securities, or other property shall be paid or transferred
in lieu of any fractional Shares, or whether such fractional Shares or any
rights thereto shall be cancelled, terminated or otherwise eliminated.

        (i)  Headings.  Headings are given to the Sections and subsections of
the Plan solely as a convenience to facilitate reference. Such headings shall
not be deemed in any way material or relevant to the construction or
interpretation of the Plan or any provision thereof.

                                MASCO CORPORATION 
                      1997 NON-EMPLOYEE DIRECTORS STOCK PLAN

SECTION 1.  PURPOSE

        The purpose of this Plan is to ensure that the non-employee Directors
of Masco Corporation (the "Company") have an equity interest in the Company and
thereby have a direct and long term interest in the growth and prosperity of
the Company by payment of part of their compensation in the form of common
stock of the Company.

SECTION 2.  ADMINISTRATION OF THE PLAN

        This Plan will be administered by the Company's Board of Directors 
(the "Board"). The Board shall be authorized to interpret the Plan, to
establish, amend, and rescind any rules and regulations relating to the Plan
and to make all other determinations necessary or advisable for the
administration of the Plan. The Board's interpretation of  the terms and
provisions of this Plan shall be final and conclusive. The Secretary of the
Company shall be authorized to implement the Plan in accordance with its terms
and to take such actions of a ministerial nature as shall be necessary to
effectuate the intent and purposes thereof.  The validity, construction and
effect of the Plan and any rules and regulations relating to the Plan shall be
determined in accordance with the laws of the State of Michigan and applicable

SECTION 3.  ELIGIBILITY

        Participation will be limited to individuals who are Eligible
Directors, as hereinafter defined.  Eligible Director shall mean any Director
of the Company who is not an employee of the Company and who receives a fee for
services as a Director.

SECTION 4.  SHARES SUBJECT TO THE PLAN

        (a) Subject to the adjustments set forth below, the aggregate number of
shares of Company Common Stock, par value $1.00 per share  ("Shares"), which
may be the subject of awards issued under the Plan shall be 500,000.  

        (b) Any Shares to be delivered under the Plan shall be made available
from newly issued Shares or from Shares reacquired by the Company, including
Shares purchased in the open market.

        (c) To the extent a Stock Option award, as hereinafter defined,
terminates without having been exercised, or an award of Restricted Stock, as
hereinafter defined,  is forfeited, the Shares subject to such Stock Option or
Restricted Stock award shall again be available for distribution in connection
with future awards under the Plan.  Shares equal in number to the Shares
surrendered to the Company in payment of the option price or withholding taxes
(if any) relating to or arising in connection with any  Restricted Stock or
Stock Option hereunder shall be added to the number of Shares then available
for future awards under clause (a) above. 

        (d)  In the event of any merger, reorganization, consolidation,
recapitalization, stock split, stock dividend, or other change in corporate
structure affecting the Shares, the aggregate number of Shares which may be
issued under the Plan, the number of Shares subject to Stock Options to be
granted under Section 6(a) hereof and the number of Shares subject to any
outstanding award of Restricted Stock or unexercised Stock Option shall be
adjusted to avoid enhancement or diminution of the benefits intended to be made
available hereunder.

SECTION 5.  DIRECTOR STOCK COMPENSATION

        (a)  The compensation of each Eligible Director for the five year
period beginning January 1, 1997 shall be  



                                      1

<PAGE>   2
payable in part with an award of Restricted Stock determined as set forth
below, and in part in cash.  Compensation for this purpose means annual
retainer fees but does not include supplemental retainer fees for committee
positions or fees for attendance at meetings, which shall be paid in cash. 
The portion of compensation payable in Restricted Stock during the five year
period shall be equal to one-half of the annual compensation paid to Eligible
Directors in the year immediately prior to the award multiplied by five, and
the balance of compensation, unless otherwise determined by the Board, shall be
payable in cash.  Each award of Restricted Stock shall vest in twenty percent
annual installments (disregarding fractional shares) on January 1 of each of
the five consecutive years following the year in which the award is made.
Subject to the approval of this Plan by the Company's stockholders, each
Eligible Director on February 18, 1997 is awarded as of that date 3,470 Shares
of Restricted Stock, based on the closing price of the Shares as reported on
the New York Stock Exchange Composite Tape ("the NYSE") on February 18, 1997. 
Cash shall be paid to an Eligible Director in lieu of a fractional share. 

        (b)  Subject to the approval of this Plan by the Company's
stockholders,  each Eligible Director who is first elected or appointed to the
Board on or after the date of the Company's 1997 annual meeting of stockholders
shall receive, as of the date of such election or appointment,  an award of
Restricted Stock determined in accordance with Section 5(a) for the five year
period beginning on January 1 of the year in which such election or appointment
occurred; provided, however, that the price of the Shares used in determining
the number of Shares of Restricted Stock which shall be issued to such Eligible
Director shall be the closing price of the Shares as reported on the NYSE on
the date on which such Eligible Director is elected or appointed, and provided,
further, that the amount of Restricted Stock awarded to any Eligible Director
who begins serving as a Director other than at the beginning of a calendar year
shall be prorated to reflect the partial service of the initial year of the
Director's term, such proration to be effected in the initial vesting. 
      
        (c)   Upon the full vesting of any award of Restricted Stock awarded
pursuant to Section 5(a) or 5(b), each affected Eligible Director shall be
eligible to receive a new award of Restricted Stock, subject to Section 4.  The
number of Shares subject to such award shall be determined generally in
accordance with the provisions of Section 5(b); provided, however, that the
Board shall have sole discretion to adjust the amount of compensation then to
be paid in the form of Shares and the terms of any such award of Shares. Except
as the Board may otherwise determine, any increase or decrease in an Eligible
Director's annual compensation during the period when such Director has an
outstanding award of Restricted Stock shall be implemented by increasing or
decreasing the cash portion of such Director's compensation.

        (d)    Each Eligible Director shall be entitled to vote and receive
dividends on the unvested portion of his or her Restricted Stock, but will not
be able to obtain a stock certificate or sell, encumber or otherwise transfer
such Restricted Stock except in accordance with the terms of the Company's 1991
Long Term Stock Incentive Plan (the "Long Term Plan").  If an Eligible
Director's term is terminated by reason of death or permanent and total
disability, the restrictions on the Restricted Stock  will lapse and such
Eligible Director's rights to the Shares will become vested on the date of such
termination.  If an Eligible Director's term is terminated for any reason other
than death or permanent and total disability, the Restricted Stock that has not
vested shall be forfeited and transferred back to the Company; provided,
however, that a pro rata portion of the  Restricted Stock which would have
vested on January 1 of  the year following the year of the Eligible Director's
termination shall vest on the date of termination, based upon the portion of
the year during which the Eligible Director served as a Director of the
Company. 

SECTION 6.  STOCK OPTION GRANT

        (a)  Subject to approval of this Plan by the Compan's stockholders,
each Eligible Director on the date of such approval will be granted on such
date a stock option to purchase 4,000  Shares (the "Stock Option"). 
Thereafter, on the date of each of the Company's subsequent annual stockholders
meetings, each person who is or becomes an Eligible Director on that date and
whose service on the Board will continue after such date shall be granted a
Stock Option, subject to Section 4, effective as of the date of such meeting.

        (b) Stock Options granted under this Section 6 shall be non-qualified 
stock options and shall have the following terms and conditions.




                                      2
<PAGE>   3

        1.  Option Price.  The option price per Share shall be equal to the
closing price of the Shares as reflected on the NYSE on the date of grant (or
if there were no sales on such date, the most recent prior date on which there
were sales). 

        2.  Term of Option.  The term of the Stock Option shall be ten years
from the date of grant, subject to earlier termination in the event of
termination of service as an Eligible Director.  If an Eligible Director's term
is terminated for any reason other than death at a time when such Director is
entitled to exercise an outstanding Stock Option, then at any time or times
within three months after termination such Stock Option may be exercised as to
all or any of the Shares which the Eligible Director was entitled to purchase
at the date of termination.  If an Eligible Director dies at a time when such
Director is entitled to exercise a Stock Option, then at any time or times
within one year after death such Stock Option may be exercised as to all or any
of the Shares which the Eligible Director was entitled to purchase immediately
prior to such Director's death.  Except as so exercised, such Stock Options
shall expire at the end of such periods.  That portion of the Stock Option not
exercisable at the time of such termination shall be forfeited and transferred
back to the Company on the date of such termination.

        3.  Exercisability.  Subject to clause 2 above, each Stock Option shall
vest and become exercisable with respect to twenty percent of the underlying
Shares on each of the first five anniversaries of the date of grant, provided
that the optionee is an Eligible Director on such date.

        4.  Method of Exercise.  A Stock Option may be exercised in whole or in
part during the period in which such Stock Option is exercisable by giving
written notice of exercise to the Company specifying the number of shares to be
purchased, accompanied by payment of the purchase price.  Payment of the
purchase price shall be made in cash, by delivery of Shares, or by any
combination of the foregoing. 

        5.  Non-Transferability.  Unless otherwise provided by the terms of the
Long Term Plan or the Board,  (i) Stock Options shall not be transferable by
the optionee other than by will or by the laws of descent and distribution, and
(ii) during the optionee's lifetime, all Stock Options shall be exercisable
only by the optionee or by his or her guardian or legal representative.

        6.  Stockholder Rights.  The holder of a Stock Option shall, as such,
have none of the rights of a stockholder.

SECTION 7.  GENERAL

        (a)   Plan Amendments.  The Board may amend, suspend or discontinue the
Plan as it shall deem advisable or to conform to any change in any law or
regulation applicable thereto; provided, that the Board may not, without the
authorization and approval of the stockholders of the Company: (a) modify the
class of persons who constitute Eligible Directors as defined in the Plan; or 
(b) increase the total number of Shares available under the Plan.  In addition,
without the consent of affected participants, no amendment of  the Plan or any
award under the Plan may impair the rights of  participants under outstanding
awards.

        (b)   Listing and Registration.  If at any time the Board shall
determine, in its discretion, that the listing, registration or qualification
of the Shares under the Plan upon any securities exchange or under any state or
Federal law, or the consent or approval of any governmental regulatory body, is
necessary or desirable as a condition of, or in connection with, the granting
of any award hereunder, no Shares may be delivered or disposed of unless such
listing, registration, qualification, consent or approval shall have been
effected or obtained free of any condition not acceptable to the Board.

        (c)  Award Agreements.    Each award of Restricted Stock and Stock
Option granted hereunder shall be evidenced by the Eligible Director's written
agreement with the Company which shall contain such terms and conditions not
inconsistent with the provisions of the Plan as shall be determined by the
Board in its discretion.

        or of the Committee;
        
                (vii) determine the methods or procedures for establishing the

        Shares or other securities) transferred, exchanged, given or received 
        with respect to the Plan or any Award;

                (viii) prescribe and amend the forms of Award Agreements and 
        other instruments required under or advisable with respect to the 
        Plan;

                (ix) designate Options granted to key employees of the Company
        or its subsidiaries as Incentive Stock Options;

                (x) interpret and administer the Plan, Award Agreements, Awards
        and any contract, document, instrument or agreement relating thereto;

                (xi) establish, amend, suspend or waive such rules and 
        regulations and appoint such agents as it shall deem appropriate for

                (xii) decide all questions and settle all controversies and 
        disputes which may arise in connection with the Plan, Award Agreements

SECTION 4.  SHARES AVAILABLE FOR AWARDS

        (a)  Shares Available.  Subject to adjustment as provided in Section 
4(c):

                (i) Initial Authorization.  There shall be 6,000,000 Shares 
        initially available for issuance under the Plan.

                (ii) Acquired Shares.  In addition to the amount set forth 
        above, up to 6,000,000 Shares acquired by the Company subsequent to 
        the 1997 Annual Meeting of Stockholders as full or partial payment for
        the exercise price for an Option or any other stock option granted by
        the Company, or acquired by the Company, in open market transactions or
        otherwise, in connection with the Plan or any Award hereunder or any
        other employee stock option or restricted stock issued by the Company
        may thereafter be included in the Shares available for Awards. If any
        Shares covered by an Award or to which an Award relates are forfeited,
        or if an Award expires, terminates or is cancelled, then the Shares
        covered by such Award, or to which such Award relates, or the number of
        Shares otherwise counted against the aggregate number of Shares
        available under the Plan by reason of such Award, to the extent of any
        such forfeiture, expiration, termination or cancellation, may
        thereafter be available for further granting of Awards and included as
        acquired Shares for purposes of the preceding sentence.
        
                (iii) Shares Under Prior Plans.  In addition to the amounts set 
        forth above, shares remaining available for issuance upon any 
        termination of authority to make further awards under both the 
        Company's 1984 Restricted Stock Incentive Plan and its 1984 Stock 
        Option Plan shall thereafter be available for issuance hereunder.

                (iv) Accounting for Awards.  For purposes of this Section 4, 

                                         3

<PAGE>   4


                        (A) if an Award (other than a Dividend Equivalent) is
                denominated in Shares, the number of Shares covered by such
                Award, or to which such Award relates, shall be counted on the
                date of grant of such Award against the aggregate number of
                Shares available for granting Awards under the Plan to the
                extent determinable on such date and insofar as the number of
                Shares is not then determinable under procedures adopted by the
                Committee consistent with the purposes of the Plan; and
        
                        (B) Dividend Equivalents and Awards not denominated in
                Shares shall be counted against the aggregate number of Shares
                available for granting Awards under the Plan in such amount and
                at such time as the Committee shall determine under procedures
                adopted by the Committee consistent with the purposes of the 
                Plan;
        
        provided, however, that Awards that operate in tandem with (whether
        granted simultaneously with or at a different time from), or that are
        substituted for, other Awards or restricted stock awards or stock
        options granted under any other plan of the Company may be counted or
        not counted under procedures adopted by the Committee in order to avoid
        double counting. Any Shares that are delivered by the Company or its
        Affiliates, and any Awards that are granted by, or become obligations
        of, the Company, through the assumption by the Company of, or in
        substitution for, outstanding restricted stock awards or stock options
        previously granted by an acquired company shall not, except in the case
        of Awards granted to Participants who are directors or officers of the
        Company for purposes of Section 16, be counted against the Shares
        available for Granting Awards under the Plan.
        
                (v) Sources of Shares Deliverable Under Awards.  Any Shares 
        delivered pursuant to an Award may consist, in whole or in part, of 
        authorized but unissued Shares or of Shares reacquired by the Company, 
        including but not limited to Shares purchased on the open market.

        (b) Individual Stock-Based Awards.  Subject to adjustment as provided
in Section 4(c), no Participant may receive Options or Stock Appreciation
Rights under the Plan in any calendar year that relate to more than 1,000,000
Shares in the aggregate; provided, however, that such number may be increased
with respect to any Participant by any Shares available for grant to such
Participant in accordance with this Paragraph 4(b) in any prior years that were
not granted in such prior year beginning on or after January 1, 1997.  No
provision of this Paragraph 4(b) shall be construed as limiting the amount of
any other stock-based or cash-based Award which may be granted to any
Participant.    

        (c)  Adjustments.  Upon the occurrence of any dividend or other
distribution (whether in the form of cash, Shares, other securities or other
property), change in the capital or shares of capital stock, recapitalization,
stock split, reverse stock split, reorganization, merger, consolidation,
split-up, spin-off, combination, repurchase, or exchange of Shares or other
securities of the Company, issuance of warrants or other rights to purchase
Shares or other securities of the Company or extraordinary transaction or event
which affects the Shares, then the Committee shall have the authority to make
such adjustment, if any, in such manner as it deems appropriate, in (i) the
number and type of Shares (or other securities or property) which thereafter
may be made the subject of Awards, (ii) outstanding Awards including without
limitation the number and type of Shares (or other securities or property)
subject thereto, and (iii) the grant, purchase or exercise price with respect
to outstanding Awards and, if deemed appropriate, make provision for cash
payments to the holders of outstanding Awards; provided, however,  that the
number of Shares subject to any Award denominated in Shares shall always be a
whole number.

SECTION 5.  ELIGIBILITY

        Any employee of or consultant to the Company or any Affiliate,
including any officer of the Company (who may also be a director,  any person
who serves only as a director of the Company and any consultant to the Company
or an Affiliate who is also a director of the Company and who is not rendering
services pursuant to a written agreement with the entity in question), as may
be selected from time to time by the Committee or by the directors to whom 

                                      4

<PAGE>   5


authority may be delegated pursuant to Section 3 hereof in its or their
discretion, is eligible to be designated a Participant.

SECTION 6.  AWARDS

        (a)  Options.  The Committee is authorized to grant Options to 
Participants.

                (i) Committee Determinations.  Subject to the terms of the 
        Plan, the Committee shall determine:

                        (A) the purchase price per Share under each Option, 
                provided, however, that such price shall not be less than 100%
                of the fair market value of the Shares underlying such Option 
                on the date of grant;

                        (B) the term of each Option; and

                        (C) the time or times at which an Option may be 
            exercised, in whole or in part, the method or methods by which and
            the form or  forms (including, without limitation, cash, Shares,
            other Awards or other property, or any combination thereof, having
            a fair market value on the exercise date equal to the relevant
            exercise price) in which payment of the exercise price with respect
            thereto may be made or deemed to have been made. The terms of any
            Incentive Stock Option granted under the Plan shall comply in all
            respects with the provisions of Section 422 of the Code, or any
            successor provision thereto, and any regulations promulgated
            thereunder.
        
        Subject to the terms of the Plan, the Committee may impose such 
        conditions or restrictions on any Option as it deems appropriate.

            (ii) Other Terms.  Unless otherwise determined by the Committee:

                  (A) A Participant electing to exercise an Option shall give
            written notice to the Company, as may be specified by the Committee,
            of exercise of the Option and the number of Shares elected for ex-
            ercise, such notice to be accompanied by such instruments or 
            documents as may be required by the Committee, and shall tender the
            purchase price of the Shares elected for exercise.

                  (B) At the time of exercise of an Option payment in full in 
            cash or in Shares (that have been held by the Participant for at 
            least six months) or any combination thereof, at the option of the
            Participant, shall be made for all Shares then being purchased.

                  (C) The Company shall not be obligated to issue any Shares
            unless and until:

                       (I) if the class of Shares at the time is listed upon any
                  stock exchange, the Shares to be issued have been listed, or
                  authorized to be added to the list upon official notice of 
                  issuance, upon such exchange, and

                       (II) in the opinion of the Company's counsel there has 
                  been compliance with applicable law in connection with the 
                  issuance and delivery of Shares and such issuance shall have
                  been approved by the Company's counsel.

                  Without limiting the generality of the foregoing, the Company
            may require from the Participant such investment representation or
            such agreement, if any, as the Company's counsel may consider
            necessary in order to comply with the Securities Act of 1933 as then
            in effect, and may require that the Participant agree that any sale
            of the Shares will be made only in such manner as shall 


                                         5

<PAGE>   6
            be in accordance with law and that the Participant will notify the
            Company of any intent to make any disposition of the Shares whether
            by sale, gift or otherwise. The Participant shall take any action
            reasonably requested by the Company in such connection. A
            Participant shall have the rights of a stockholder only as and when
            Shares have been actually issued to the Participant pursuant to the
            Plan.
        
                  (D) If the employment of or consulting arrangement with a
            Participant terminates for any reason (including termination by
            reason of the fact that an entity is no longer an Affiliate) other
            than the Participant's death, the Participant may thereafter
            exercise the Option as provided below, except that the Committee
            may terminate the unexercised portion of the Option concurrently
            with or at any time following termination of the employment or
            consulting arrangement (including termination of employment upon a
            change of status from employee to consultant) if it shall determine
            that the Participant has engaged in any activity detrimental to the
            interests of the Company or an Affiliate. If such termination is
            voluntary on the part of the Participant, the option may be
            exercised only within ten days after the date of termination. If
            such termination is involuntary on the part of the Participant, if
            an employee retires on or after normal retirement date or if the
            employment or consulting relationship is terminated by reason of
            permanent and total disability, the Option may be exercised within
            three months after the date of termination or retirement. For
            purposes of this Paragraph (D), a Participant's employment or
            consulting arrangement shall not be considered terminated (i) in
            the case of approved sick leave or other bona fide leave of absence
            (not to exceed one year), (ii) in the case of a transfer of
            employment or the consulting arrangement among the Company and
            Affiliates, or (iii) by virtue of a change of status from employee
            to consultant or from consultant to employee, except as provided
            above.
        
                  (E) If a Participant dies at a time when entitled to exercise
            an Option, then at any time or times within one year after death 
            such Option may be exercised, as to all or any of the Shares which
            the Participant was entitled to purchase immediately prior to 
            death.  The Company may decline to deliver Shares to a designated
            beneficiary until it receives indemnity against claims of third
            parties satisfactory to the Company. Except as so exercised such
            Option shall expire at the end of such period.
        
                  (F) An Option may be exercised only if and to the extent such
            Option was exercisable at the date of termination of employment or
            the consulting arrangement, and an Option may not be exercised at a
            time when the Option would not have been exercisable had the
            employment or consulting arrangement continued.
        
            (iii) Restoration Options.  The Committee may grant a Participant 
      the right to receive a restoration Option with respect to an Option or
      any other option granted by the Company.  Unless the Committee shall
      otherwise determine, a restoration Option shall provide that the
      underlying option must be exercised while the Participant is an employee
      of or consultant to the Company or an Affiliate and the number of Shares
      which are subject to a restoration Option shall not exceed the number
      of whole Shares exchanged in payment of the original option.
        
        (b)  Stock Appreciation Rights.  The Committee is authorized to grant
Stock Appreciation Rights to Participants. Subject to the terms of the Plan, a
Stock Appreciation Right granted under the Plan shall confer on the holder
thereof a right to receive, upon exercise thereof, the excess of (i) the fair
market value of one Share on the date of exercise or, if the Committee shall so
determine in the case of any such right other than one related to any Incentive
Stock Option, at any time during a specified period before or after the date of
exercise over (ii) the grant price of the right as specified by the Committee.
Subject to the terms of the Plan, the Committee shall determine the grant
price, term, methods of exercise and settlement and any other terms and
conditions of any Stock Appreciation Right and may impose such conditions or
restrictions on the exercise of any Stock Appreciation Right as it may deem
appropriate.

                                         6
<PAGE>   7
      (c)  Restricted Stock and Restricted Stock Units.

            (i) Issuance.  The Committee is authorized to grant to Participants
      Awards of Restricted Stock, which shall consist of Shares, and Restricted
      Stock Units which shall give the Participant the right to receive cash,
      other securities, other Awards or other property, in each case subject to
      the termination of the Restricted Period determined by the Committee.

            (ii) Restrictions.  The Restricted Period may differ among
      Participants and may have different expiration dates with respect to
      portions of Shares covered by the same Award.  Subject to the terms of the
      Plan, Awards of Restricted Stock and Restricted Stock Units shall have 
      such restrictions as the Committee may impose (including, without
      limitation, limitations on the right to vote Restricted Stock or the
      right to receive any dividend or other right or property), which
      restrictions may lapse separately or in combination at such time or
      times, in installments or otherwise. Unless the Committee shall otherwise
      determine, any Shares or other securities distributed with respect to
      Restricted Stock or which a Participant is otherwise entitled to receive
      by reason of such Shares shall be subject to the restrictions contained
      in the applicable Award Agreement. Subject to the aforementioned
      restrictions and the provisions of the Plan, Participants shall have all
      of the rights of a stockholder with respect to Shares of Restricted
      Stock.
        
            (iii) Registration.  Restricted Stock granted under the Plan may be
      evidenced in such manner as the Committee may deem appropriate, including,
      without limitation, book-entry registration or issuance of stock certifi-
      cates.

            (iv) Forfeiture.  Except as otherwise determined by the Committee:

                  (A) If the employment of or consulting arrangement with a
            Participant terminates for any reason (including termination by 
            reason of the fact that any entity is no longer an Affiliate),
            other than the Participant's death or permanent and total
            disability or, in the case of an employee, retirement on or after
            normal retirement date, all Shares of Restricted Stock theretofore
            awarded to the Participant which are still subject to restrictions
            shall upon such termination of employment or the consulting
            relationship be forfeited and transferred back to the Company.
            Notwithstanding the foregoing or Paragraph (C) below, if a
            Participant continues to hold an Award of Restricted Stock
            following termination of the employment or consulting arrangement
            (including retirement and termination of employment upon a change
            of status from employee to consultant), the Shares of Restricted
            Stock which remain subject to restrictions shall nonetheless be
            forfeited and transferred back to the Company if the Committee at
            any time thereafter determines that the Participant has engaged in
            any activity detrimental to the interests of the Company or an
            Affiliate. For purposes of this Paragraph (A), a Participant's
            employment or consulting arrangement shall not be considered
            terminated (i) in the case of approved sick leave or other bona
            fide leave of absence (not to exceed one year), (ii) in the case of
            a transfer of employment or the consulting arrangement among the
            Company and Affiliates, or (iii) by virtue of a change of status
            from employee to consultant or from consultant to employee, except
            as provided above.
        
                  (B) If a Participant ceases to be employed or retained by the
            Company or an Affiliate by reason of death or permanent and total
            disability or if following retirement a Participant continues to 
            have rights under an Award of Restricted Stock and thereafter dies,
            the restrictions contained in the Award shall lapse with respect to
            such Restricted Stock.

                  (C) If an employee ceases to be employed by the Company or an
            Affiliate by reason of retirement on or after normal retirement 
            date, the restrictions contained in the Award of Restricted Stock 
            shall continue to lapse in the same manner as though employment had 
            not terminated.

<PAGE>   8


                  (D) At the expiration of the Restricted Period as to Shares
            covered by an Award of Restricted Stock, the Company shall deliver
            the Shares as to which the Restricted Period has expired, as 
            follows:

                        (1) if an assignment to a trust has been made in 
                accordance with Section 6(g)(iv)(B)(2)(c), to such trust; or

                        (2) if the Restricted Period has expired by reason of 
                death and a beneficiary has been designated in form approved by
                the Company, to the beneficiary so designated; or

                        (3) in all other cases, to the Participant or the legal
                representative of the Participant's estate.

        (d)  Performance Awards.  The Committee is authorized to grant
Performance Awards to Participants. Subject to the terms of the Plan, a
Performance Award granted under the Plan (i) may be denominated or payable in
cash, Shares (including, without limitation, Restricted Stock), other
securities, other Awards, or other property and (ii) shall confer on the holder
thereof rights valued as determined by the Committee and payable to, or
exercisable by, the holder of the Performance Award, in whole or in part, upon
the achievement of such performance goals during such performance periods as
the Committee shall establish. Subject to the terms of the Plan, the
performance goals to be achieved during any performance period, the length of
any performance period, the amount of any Performance Award granted, the amount
of any payment or transfer to be made pursuant to any Performance Award and
other terms and conditions shall be determined by the Committee.

        (e)  Dividend Equivalents.  The Committee is authorized to grant to
Participants Awards under which the holders thereof shall be entitled to
receive payments equivalent to dividends or interest with respect to a number
of Shares determined by the Committee, and the Committee may provide that such
amounts (if any) shall be deemed to have been reinvested in additional Shares
or otherwise reinvested. Subject to the terms of the Plan, such Awards may have
such terms and conditions as the Committee shall determine.

        (f)  Other Stock-Based Awards.  The Committee is authorized to grant to
Participants such other Awards that are denominated or payable in, valued in
whole or in part by reference to or otherwise based on or related to Shares
(including, without limitation, securities convertible into Shares), as are
deemed by the Committee to be consistent with the purposes of the Plan,
provided, however, that such grants to persons who are subject to Section 16
must comply with the provisions of Rule 16b-3. Subject to the terms of the
Plan, the Committee shall determine the terms and conditions of such Awards.
Shares or other securities delivered pursuant to a purchase right granted under
this Section 6(f) shall be purchased for such consideration, which may be paid
by such method or methods and in such form or forms, including, without
limitation, cash, Shares, other securities, other Awards or other property or
any combination thereof, as the Committee shall determine.

        (g)  General.

            (i) No Cash Consideration for Awards.  Awards may be granted for no
      cash consideration or for such minimal cash consideration as may be 
      required by applicable law.

            (ii) Awards May Be Granted Separately or Together.  Awards may, in 
      the discretion of the Committee, be granted either alone or in addition
      to, in tandem with or in substitution for any other Award or any award
      granted under any other plan of the Company or any Affiliate. Awards
      granted in addition to or in tandem with other Awards or in addition to
      or in tandem with awards granted under another plan of the Company or any
      Affiliate, may be granted either at the same time as or at a different
      time from the grant of such other Awards or awards.

            (iii) Forms of Payment Under Awards.  Subject to the terms of the 
      Plan and of any applicable Award Agreement, payments or transfers to be
      made by the Company or an Affiliate upon the grant, exercise, or payment
      of an Award may be made in such form or forms as the Committee shall
      determine, including, without limitation, cash, Shares, other securities,
      other Awards, or other property, or any combination thereof, and may be
      made in a single payment or transfer, in installments, or on a deferred
      basis, in each case in accordance with rules and procedures established
      by the Committee. Such rules and procedures may include, without
      limitation, provisions for the payment or crediting of reasonable
      interest on installment or deferred payments or the grant or crediting of
      Dividend Equivalents in respect of installment or deferred payments.
        
            (iv) Limits on Transfer of Awards.

                  (A) Except as the Committee may otherwise determine, no Award
            or right under any Award may be sold, encumbered, pledged, 
            alienated, attached, assigned or transferred in any manner and any
            attempt to do any of the foregoing shall be void and unenforceable
            against the Company.

                  (B) Notwithstanding the provisions of Paragraph (A) above:

                       (1) An Option may be transferred:

                             (a) to a beneficiary designated by the Participant
                        in writing on a form approved by the Committee; 

                             (b) by will or the applicable laws of descent and 
                        distribution to the personal representative, executor or
                        administrator of the Participant's estate; or

                             (c) to a revocable grantor trust established by the
                        Participant for the sole benefit of the Participant 
                        during the Participant's life, and under the terms of
                        which the Participant is and remains the sole trustee
                        until death or physical or mental incapacity. Such
                        assignment shall be effected by a written instrument in
                        form and content satisfactory to the Committee, and the
                        Participant shall deliver to the Committee a true copy
                        of the agreement or other document evidencing such
                        trust. If in the judgment of the Committee the trust to
                        which a Participant may attempt to assign rights
                        under such an Award does not meet the criteria of a
                        trust to which an assignment is permitted by the terms
                        hereof, or if after assignment, because of amendment,
                        by force of law or any other reason such trust no
                        longer meets such criteria, such attempted assignment
                        shall be void and may be disregarded by the Committee
                        and the Company and all rights to any such Options
                        shall revert to and remain solely in the Participant.
                        Notwithstanding a qualified assignment, the
                        Participant, and not the trust to which rights under
                        such an Option may be assigned, for the purpose of
                        determining compensation arising by reason of the
                        Option hall continue to be considered an employee or
                        consultant, as the case may be, of the Company or an
                        Affiliate, but such trust and the Participant shall be
                        bound by all of the terms and conditions of the Award
                        Agreement and this Plan. Shares issued in the name of
                        and delivered to such trust shall be conclusively
                        considered issuance and delivery to the Participant.
        
                        (2) A Participant may assign or transfer rights under an
                  Award of Restricted Stock or Restricted Stock Units:

                             (a) to a beneficiary designated by the 
                  Participant in writing on a form approved by the Committee;



                                         9

<PAGE>   10



                              (b) by will or the applicable laws of descent and
                        distribution to the personal representative, executor or
                        administrator of the Participant's estate; or

                              (c) to a revocable grantor trust established by 
                        the Participant for the sole benefit of the Participant
                        during the Participant's life, and under the terms of
                        which the Participant is and remains the sole trustee
                        until death or physical or mental incapacity. Such
                        assignment shall be effected by a written instrument in
                        form and content satisfactory to the Committee, and the
                        Participant shall deliver to the Committee a true copy
                        of the agreement or other document evidencing such
                        trust. If in the judgment of the Committee the trust to
                        which a Participant may attempt to assign rights
                        under such an Award does not meet the criteria of a
                        trust to which an assignment is permitted by the terms
                        hereof, or if after assignment, because of amendment,
                        by force of law or any other reason such trust no
                        longer meets such criteria, such attempted assignment
                        shall be void and may be disregarded by the Committee
                        and the Company and all rights to any such Awards shall
                        revert to and remain solely in the Participant.
                        Notwithstanding a qualified assignment, the
                        Participant, and not the trust to which rights under
                        such an Award may be assigned, for the purpose of
                        determining compensation arising by reason of the Award
                        shall continue to be considered an employee or
                        consultant, as the case may be, of the Company or an
                        Affiliate, but such trust and the Participant shall be
                        bound by all of the terms and conditions of the Award
                        Agreement and this Plan. Shares issued in the name of
                        and delivered to such trust shall be conclusively
                        considered issuance and delivery to the Participant.
        
                        (3) The Committee shall not permit directors or officers
                  of the Company for purposes of Section 16 to transfer or 
                  assign Awards except as permitted under Rule 16b-3.

                  (C) The Committee, the Company and its officers, agents and
            employees may rely upon any beneficiary designation, assignment or
            other instrument of transfer, copies of trust agreements and any
            other documents delivered to them by or on behalf of the
            Participant which they believe genuine and any action taken by them
            in reliance thereon shall be conclusive and binding upon the
            Participant, the personal representatives of the Participant's
            estate and all persons asserting a claim based on an Award. The
            delivery by a Participant of a beneficiary designation, or an
            assignment of rights under an Award as permitted hereunder, shall
            constitute the Participant's irrevocable undertaking to hold the
            Committee, the Company and its officers, agents and employees
            harmless against claims, including any cost or expense incurred in
            defending against claims, of any person (including the Participant)
            which may be asserted or alleged to be based on an Award subject to
            a beneficiary designation or an assignment. In addition, the
            Company may decline to deliver Shares to a beneficiary until it
            receives indemnity against claims of third parties satisfactory to
            the Company.
        
            (v) Share Certificates.  All certificates for Shares or other
      securities delivered under the Plan pursuant to any Award or the exercise
      thereof shall be subject to such stop transfer orders and other
      restrictions as the Committee may deem advisable under the Plan or the
      rules, regulations and other requirements of the Securities and Exchange
      Commission, any stock exchange upon which such Shares or other securities
      are then listed and any applicable Federal or state securities laws, and
      the Committee may cause a legend or legends to be put on any such
      certificates to make appropriate reference to such restrictions.
        
            (vi) Change in Control.  (A) Notwithstanding any of the provisions 
      of this Plan or instruments evidencing Awards granted hereunder, upon a
      Change in Control of the Company (as hereinafter defined) the vesting of
      all rights of Participants under outstanding Awards shall be accelerated
      and all restrictions thereon shall terminate in order that Participants
      may fully realize the benefits thereunder. Such acceleration shall 
        
                                        10


<PAGE>   11
      include, without limitation, the immediate exercisability in full of all
      Options and the termination of restrictions on Restricted Stock and
      Restricted Stock Units. Further, in addition to the Committee's authority
      set forth in Section 4(c), the Committee, as constituted before such
      Change in Control, is authorized, and has sole discretion, as to any
      Award, either at the time such Award is made hereunder or any time
      thereafter, to take any one or more of the following actions: (i) provide
      for the purchase of any such Award, upon the Participant's request, for
      an amount of cash equal to the amount that could have been attained upon
      the exercise of such Award or realization of the Participant's rights had
      such Award been currently exercisable or payable; (ii) make such
      adjustment to any such Award then outstanding as the Committee deems
      appropriate to reflect such Change in Control; and (iii) cause any such
      Award then outstanding to be assumed, or new rights substituted
      therefore, by the acquiring or surviving  after such Change in Control.
        
            (B)   With respect to any Award granted hereunder prior to 
      December 6, 1995, a Change in Control shall occur if:

                  (1) any "person" or "group of persons" as such terms are used
            in Sections 13(d) and 14(d) of the Exchange Act, other than
            pursuant to a transaction or agreement previously approved by the
            Board of Directors of the Company, directly or indirectly purchases
            or otherwise becomes the "beneficial owner" (as defined in Rule
            13d-3 under the Exchange Act) or has the right to acquire such
            beneficial ownership (whether or not such right is exercisable
            immediately, with the passage of time, or subject to any condition)
            of voting securities representing 25 percent or more of the
            combined voting power of all outstanding voting securities of (A)
            the Company  or (B) Masco Corporation, a Delaware corporation
            ("Masco"); or
        
                  (2) during any period of twenty-four consecutive calendar
            months, the individuals who at the beginning of such period 
            constitute the Company's or Masco's Board of Directors, and any new
            directors whose election by such Board or nomination for election by
            stockholders was approved by a vote of at least two-thirds of the
            members of such Board who were either directors on such Board at the
            beginning of the period or whose election or nomination for election
            as directors was previously so approved, for any reason cease to
            constitute at least a majority of the members thereof.

            (C)   Notwithstanding the provisions of subparagraph (B), with 
      respect to Awards granted hereunder on or after December 6, 1995, a
      Change in Control shall occur only if the event described in this
      subparagraph (C) shall have occurred.  With respect to any other Award
      granted prior thereto, a Change in Control shall occur if any of the
      events described in subparagraphs (B) or (C) shall have occurred, unless
      the holder of any such Award shall have consented to the application of
      this subparagraph (C) in lieu of the foregoing subparagraph (B).  A
      Change in Control for purposes of this subparagraph (C) shall occur if,
      during any period of twenty-four consecutive calendar months, the
      individuals who at the beginning of such period constitute the Company's
      Board of Directors, and any new directors (other than Excluded Directors,
      as hereinafter defined), whose election by such Board or nomination for
      election by stockholders was approved by a vote of at least two-thirds of
      the members of such Board who were either directors on such Board at the
      beginning of the period or whose election or nomination for election as
      directors was previously so approved, for any reason cease to constitute
      at least a majority of the members thereof.  For purposes hereof,
      "Excluded Directors" are directors whose election by the Board or
      approval by the Board for stockholder election occurred within one year
      of any "person" or "group of persons", as such terms are used in Sections
      13(d) and 14(d) of the Exchange Act, commencing a tender offer for, or
      becoming the beneficial owner of, voting securities representing 25
      percent or more of the combined voting power of all outstanding voting
      securities of the Company, other than pursuant to a tender offer approved
      by the Board prior to its commencement or pursuant to stock acquisitions
      approved by the Board prior to their representing 25 percent or more of
      such combined voting power.

            (D) (1)     In the event that subsequent to a Change in Control it
      is determined that any payment or distribution by the Company to or for 
      the benefit of a Participant, whether paid or payable or distributed or
      distributable pursuant to the terms of this Plan or otherwise, other than
      any payment pursuant to this subparagraph (D) (a "Payment"), would be
      subject to the excise tax imposed by Section 4999 of the Code or any
      interest or penalties with respect to such excise tax (such excise tax,
      together with any such interest and penalties, are hereinafter
      collectively referred to as the "Excise Tax"), then such Participant
      shall be entitled to receive from the Company, within 15 days following
      the determination described in (2) below, an additional payment ("Excise
      Tax Adjustment Payment") in an amount such that after payment by such
      Participant of all applicable Federal, state and local taxes (computed at
      the maximum marginal rates and including any interest or penalties
      imposed with respect to such taxes), including any Excise Tax, imposed
      upon the Excise Tax Adjustment Payment, such Participant retains an
      amount of the Excise Tax Adjustment Payment equal to the Excise Tax
      imposed upon the Payments.
        
            (2)   All determinations required to be made under this Section
      6(g)(vi)(D), including whether an Excise Tax Adjustment Payment is 
      required and the amount of such Excise Tax Adjustment Payment, shall be
      made by Coopers & Lybrand L.L.P., or such other national accounting firm
      as the Company, or, subsequent to a Change in Control, the Company and
      the Participant jointly, may designate, for purposes of the Excise Tax,
      which shall provide detailed supporting calculations to the Company and
      the affected Participant within 15 business days of the date of the
      applicable Payment.  Except as hereinafter provided, any determination by
      Coopers & Lybrand L.L.P., or such other national accounting firm, shall
      be binding upon the Company and the Participant.  As a result of the
      uncertainty in the application of Section 4999 of the Code that may exist
      at the time of the initial determination hereunder, it is possible that
      (x) certain Excise Tax Adjustment Payments will not have been made by the
      Company which should have been made (an "Underpayment"), or (y) certain
      Excise Tax Adjustment Payments will have been made which should not have
      been made (an "Overpayment"), consistent with the calculations required
      to be made hereunder.  In the event of an Underpayment, such Underpayment
      shall be promptly paid by the Company to or for the benefit of the
      affected Participant.  In the event that the Participant discovers that
      an Overpayment shall have occurred, the amount thereof shall be promptly
      repaid to the Company.
        
            (3)   This Section 6(g)(vi)(D) shall not apply to any Award (x) that
      was granted prior to February 17, 1993 and (y) the holder of which is an
      executive officer of the Company, as determined under the Exchange Act.

            (vii)  Cash Settlement.  Notwithstanding any provision of this Plan
      or of any Award Agreement to the contrary, any Award outstanding 
      hereunder may at any time be cancelled in the Committee's sole 
      discretion upon payment of the value of such Award to the holder thereof 
      in cash or in another Award hereunder, such value to be determined by the
      Committee in its sole discretion.

SECTION 7.  AMENDMENT AND TERMINATION

        Except to the extent prohibited by applicable law and unless otherwise
expressly provided in an Award Agreement or in the Plan:

        (a)  Amendments to the Plan.  The Board of Directors of the Company may 
amend the Plan and the Board of Directors or the Committee may amend any out-
standing Award; provided, however,  that (i) no Plan amendment shall be
effective until approved by stockholders of the Company insofar as stockholder
approval thereof is required in order for the Plan to continue to satisfy the
conditions of Rule 16b-3, and (ii) without the consent of affected Participants
no amendment of the Plan or of any Award may impair the rights of Participants
under outstanding Awards, and (iii) no Option may be amended to reduce its
initial exercise price other than in connection with an event described in
Section 4(c) hereof.


                                        12

<PAGE>   13
        (b)  Waivers.  The Committee may waive any conditions or rights under
any Award theretofore granted, prospectively or retroactively, without the
consent of any Participant.

        (c)  Adjustments of Awards Upon the Occurrence of Certain Unusual or
Nonrecurring Events.  The Committee shall be authorized to make adjustments in
the terms and conditions of, and the criteria included in, Awards in
recognition of unusual or nonrecurring events (including, without limitation,
the events described in Section 4(b) hereof) affecting the Company, any
Affiliate, or the financial statements of the Company or any Affiliate, or of
changes in applicable laws, regulations, or accounting principles, whenever the
Committee determines that such adjustments are appropriate in order to prevent
dilution or enlargement of the benefits or potential benefits to be made
available under the Plan.

        (d)  Correction of Defects, Omissions, and Inconsistencies.  The
Committee may correct any defect, supply any omission or reconcile any
inconsistency in the Plan or any Award in the manner and to the extent it shall
deem desirable to effectuate the Plan. 

SECTION 8.  GENERAL PROVISIONS

        (a)  No Rights to Awards.  No Participant or other person shall have
any claim to be granted any Award under the Plan, and there is no obligation
for uniformity of treatment of Participants or holders or beneficiaries of
Awards under the Plan. The terms and conditions of Awards of the same type and
the determination of the Committee to grant a waiver or modification of any
Award and the terms and conditions thereof need not be the same with respect to
each Participant.

        (b)  Withholding.  The Company or any Affiliate shall be authorized to
withhold from any Award granted or any payment due or transfer made under any
Award or under the Plan the amount (in cash, Shares, other securities, other
Awards or other property) of withholding taxes due in respect of an Award, its
exercise or any payment or transfer under such Award or under the Plan and to
take such other action as may be necessary in the opinion of the Company or
Affiliate to satisfy all obligations for the payment of such taxes.

        (c)  No Limit on Other Compensation Arrangements.  Nothing contained in
the Plan shall prevent the Company or any Affiliate from adopting or continuing
in effect other or additional compensation arrangements, including the grant of
options and other stock-based awards, and such arrangements may be either
generally applicable or applicable only in specific cases.

        (d)  No Right to Employment.  The grant of an Award shall not be
construed as giving a Participant the right to be retained in the employ of the
Company or any Affiliate. Further, the Company or an Affiliate may at any time
dismiss a Participant from employment, free from any liability, or any claim
under the Plan, unless otherwise expressly provided in the Plan or in any Award
Agreement or other written agreement with the Participant.

        (e)  Governing Law.  The validity, construction and effect of the Plan
and any rules and regulations relating to the Plan shall be determined in
accordance with the laws of the State of Michigan and applicable Federal law.

        (f)  Severability.  If any provision of the Plan or any Award is or
becomes or is deemed to be invalid, illegal or unenforceable in any
jurisdiction or as to any person or Award, or would disqualify the Plan or any
Award under any law deemed applicable by the Committee, such provision shall be
construed or deemed amended to conform to applicable laws, or if it cannot be
so construed or deemed amended without, in the determination of the Committee,
materially altering the intent of the Plan or the Award, such provision shall
be stricken as to such jurisdiction, person or Award, and the remainder of the
Plan and any such Award shall remain in full force and effect.

        (g)  No Trust or Fund Created.  Neither the Plan nor any Award shall
create or be construed to create a trust or separate fund of any kind or a
fiduciary relationship between the Company or any Affiliate and a Participant
or any other person. To the extent that any person acquires a right to receive
payments from the Company or any Affiliate pursuant to an Award, such right
shall be no greater than the right of any unsecured general creditor of the
Company or any Affiliate.

        (h)  No Fractional Shares.  No fractional Shares shall be issued or
delivered pursuant to the Plan or any Award, and the Committee shall determine
whether cash, other securities, or other property shall be paid or transferred
in lieu of any fractional Shares, or whether such fractional Shares or any
rights thereto shall be cancelled, terminated or otherwise eliminated.

        (i)  Headings.  Headings are given to the Sections and subsections of
the Plan solely as a convenience to facilitate reference. Such headings shall
not be deemed in any way material or relevant to the construction or
interpretation of the Plan or any provision thereof.

        The individuals eligible to participate in the Plan (the
"Participants") are the executive officers of the Company.

        Each Performance Period for purposes of the Plan shall have a duration
of one calendar year, commencing January 1 and ending December 31.

(the "Committee") shall have the full power and authority to administer and

performance criteria shall consist of one or more of the following: net income,
earnings per share, cash flow, revenues, return on assets or total shareholder
return.

SECTION 6.  AWARDS

        On or before the 90th day of each Performance Period, the Committee
shall establish in writing a performance incentive award for such Participants
as shall be designated by the Committee and in such amounts as the Committee
shall determine, subject to the limitations of the Plan.  No award to any

certify the amount of the award to each Participant for such Performance
Period.  Payments of the awards shall be made in cash.  To the extent net

from discontinued operations, extraordinary losses (in accordance with
generally accepted accounting principles, as currently in effect), the
cumulative effect of changes in accounting principles and other unusual,
nonrecurring items of loss that are separately identified and quantified in the

                      1997 NON-EMPLOYEE DIRECTORS STOCK PLAN

SECTION 1.  PURPOSE

      The purpose of this Plan is to ensure that the non-employee Directors of
MascoTech, Inc.  (the "Company") have an equity interest in the Company and
thereby have a direct and long term interest in the growth and prosperity of the
Company by payment of part of their compensation in the form of common stock of
the Company.

SECTION 2.  ADMINISTRATION OF THE PLAN

        This Plan will be administered by the Company's Board of Directors 
(the "Board"). The Board shall be authorized to interpret the Plan, to
establish, amend, and rescind any rules and regulations relating to the Plan
and to make all other determinations necessary or advisable for the
administration of the Plan. The Board's interpretation of  the terms and
provisions of this Plan shall be final and conclusive. The Secretary of the
Company shall be authorized to implement the Plan in accordance with its terms
and to take such actions of a ministerial nature as shall be necessary to
effectuate the intent and purposes thereof.  The validity, construction and
effect of the Plan and any rules and regulations relating to the Plan shall be
determined in accordance with the laws of the State of Michigan and applicable
Federal law.

SECTION 3.  ELIGIBILITY

        Participation will be limited to individuals who are Eligible
Directors, as hereinafter defined.  Eligible Director shall mean any Director
of the Company who is not an employee of the Company and who receives a fee for
service as a Director.

SECTION 4.  SHARES SUBJECT TO THE PLAN

        (a) Subject to the adjustments set forth below, the aggregate number of
shares of Company Common Stock, par value $1.00 per share  ("Shares"), which
may be the subject of awards issued under the Plan shall be 500,000.  

        (b) Any Shares to be delivered under the Plan shall be made available
from newly issued Shares or from Shares reacquired by the Company, including
Shares purchased in the open market.

        (c) To the extent a Stock Option award, as hereinafter defined,
terminates without having been exercised, or an award of Restricted Stock, as
hereinafter defined,  is forfeited, the Shares subject to such Stock Option or
Restricted Stock award shall again be available for distribution in connection
with future awards under the Plan.  Shares equal in number to the Shares
surrendered to the Company in payment of the option exercise price or
withholding taxes (if any) relating to or arising in connection with any 
Restricted Stock or Stock Option hereunder shall be added to the number of
Shares then available for future awards under clause (a) above. 

        (d)  In the event of any merger, reorganization, consolidation,
recapitalization, stock split, stock dividend, or other change in corporate
structure affecting the Shares, the aggregate number of Shares which may be
issued under the Plan, the number of Shares subject to Stock Options to be
granted under Section 6(a) hereof and the number of Shares subject to any
outstanding award of Restricted Stock or unexercised Stock Option shall be
adjusted to avoid enhancement or diminution of the benefits intended to be made
available hereunder.

<PAGE>   2
SECTION 5.  DIRECTOR STOCK COMPENSATION

        (a)  The compensation of each Eligible Director for the five year
period beginning January 1, 1997 shall be payable in part with an award of
Restricted Stock determined as set forth below, and in part in cash. 
Compensation for this purpose means annual retainer fees but does not include
supplemental retainer fees for committee positions or fees for attendance at
meetings, which shall be paid in cash.  The portion of compensation payable in
Restricted Stock during the five year period shall be equal to one-half of the
annual compensation paid to Eligible Directors in the year immediately prior to
the award multiplied by five, and the balance of compensation, unless otherwise
determined by the Board, shall be payable in cash.  Each award of Restricted
Stock shall vest in twenty percent annual installments (disregarding fractional
shares) on January 1 of each of the five consecutive years following the year
in which the award is made. Subject to the approval of this Plan by the
Company's stockholders, each Eligible Director on February 17, 1997 is awarded
as of that date 5,790 Shares of Restricted Stock, based on the closing price of
the Shares as reported on the New York Stock Exchange Composite Tape (the
"NYSE") on February 14, 1997, the last trading date preceding the grant.  Cash
shall be paid to an Eligible Director in lieu of a fractional share. 

        (b)  Subject to the approval of this Plan by the Company's 
stockholders,  each Eligible Director who is first elected or appointed to the
Board on or after the date of the Company's 1997 annual meeting of stockholders
shall receive, as of the date of such election or appointment,  an award of
Restricted Stock determined in accordance with Section 5(a) for the five year
period beginning on January 1 of the year in which such election or appointment
occurred; provided, however, that the price of the Shares used in determining
the number of Shares of Restricted Stock which shall be issued to such Eligible
Director shall be the closing price of the Shares as reported on the NYSE on
the date on which such Eligible Director is elected or appointed, and provided,
further, that the amount of Restricted Stock awarded to any Eligible Director
who begins serving as a Director other than at the beginning of a calendar year
shall be prorated to reflect the partial service of the initial year of such
Director's term, such proration to be effected in the initial vesting. 
      
        (c)   Upon the full vesting of any award of Restricted Stock awarded
pursuant to Section 5(a) or 5(b), each affected Eligible Director shall be
eligible to receive a new award of Restricted Stock, subject to Section 4.  The
number of Shares subject to such award shall be determined generally in
accordance with the provisions of Section 5(b); provided, however, that the
Board shall have sole discretion to adjust the amount of compensation then to
be paid in the form of Shares and the terms of any such award of Shares. 
Except as the Board may otherwise determine, any increase or decrease in an
Eligible Director's annual compensation during the period when such Director
has an outstanding award of Restricted Stock shall be implemented by increasing
or decreasing the cash portion of such Director's compensation.

        (d) Each Eligible Director shall be entitled to vote and receive
dividends on the unvested portion of his or her Restricted Stock, but will not
be able to obtain a stock certificate or sell, encumber or otherwise transfer
such Restricted Stock except in accordance with the terms of the Company's 1991
Long Term Stock Incentive Plan (the "Long Term Plan").  If an Eligible
Director's term is terminated by reason of death or permanent and total
disability, the restrictions on the Restricted Stock  will lapse and such
Eligible Director's rights to the Shares will become vested on the date of such
termination.  If an Eligible Director's term is terminated for any reason other
than death or permanent and total disability, the Restricted Stock that has not
vested shall be forfeited and transferred back to the Company; provided,
however, that a pro rata portion of the  Restricted Stock which would have
vested on January 1 of  the year following the year of the Eligible Director's
termination shall vest on the date of termination, based upon the portion of
the year during which the Eligible Director served as a Director of the
Company. 

SECTION 6.  STOCK OPTION GRANT



                                         2

<PAGE>   3
        (a)  Subject to approval of this Plan by the Company's stockholders,
each Eligible Director on the date of such approval will be granted on such
date a stock option to purchase 5,000  Shares (the "Stock Option"). 
Thereafter, on the date of each of the Company's subsequent annual stockholders
meetings, each person who is or becomes an Eligible Director on that date and
whose service on the Board will continue after such date shall be granted a
Stock Option, subject to Section 4, effective as of the date of such meeting.

        (b) Stock Options Granted under this Section 6 shall be non-qualified
stock options and shall have the following terms and conditions.

        1.  Option Price.  The option price per Share shall be equal to the
closing price of the Shares as reflected on the NYSE on the date of grant (or
if there were no sales on such date, the most recent prior date on which there
were sales). 

        2.  Term of Option.  The term of the Stock Option shall be ten years
from the date of grant, subject to earlier termination in the event of
termination of service as an Eligible Director.  If an Eligible Director's term
is terminated for any reason other than death at a time when such Director is
entitled to exercise an outstanding Stock Option, then at any time or times
within three months after termination such Stock Option may be exercised as to
all or any of the Shares which the Eligible Director was entitled to purchase
at the date of termination.  If an Eligible Director dies at a time when such
Director is entitled to exercise a Stock Option, then at any time or times
within one year after death such Stock Option may be exercised as to all or any
of the Shares which the Eligible Director was entitled to purchase immediately
prior to such Director's death.  Except as so exercised, such Stock Options
shall expire at the end of such periods.  That portion of the Stock Option not
exercisable at the time of such termination shall be forfeited and transferred
back to the Company on the date of such termination.

        3.  Exercisability.  Subject to clause 2 above, each Stock Option shall
vest and become exercisable with respect to twenty percent of the underlying
Shares on each of the first five anniversaries of the date of grant, provided
that the optionee is an Eligible Director on such date.

        4.  Method of Exercise.  A Stock Option may be exercised in whole or in
part during the period in which such Stock Option is exercisable by giving
written notice of exercise to the Company specifying the number of shares to be
purchased, accompanied by payment of the purchase price.  Payment of the
purchase price shall be made in cash, by delivery of Shares, or by any
combination of the foregoing. 

        5.  Non-Transferability.  Unless otherwise provided by the terms of the
Long Term Plan or the Board,  (i) Stock Options shall not be transferable by
the optionee other than by will or by the laws of descent and distribution, and
(ii) during the optionee's lifetime, all Stock Options shall be exercisable
only by the optionee or by his or her guardian or legal representative.

        6.  Stockholder Rights.  The holder of a Stock Option shall, as such,
have none of the rights of a stockholder.

SECTION 7.  GENERAL

        (a)   Plan Amendments.  The Board may amend, suspend or discontinue the
Plan as it shall deem advisable or to conform to any change in any law or
regulation applicable thereto; provided, that the Board may not, without the
authorization and approval of the stockholders of the Company: (a) modify the
class of persons who constitute Eligible Directors as defined in the Plan; or 
(b) increase the total number of Shares available under the Plan.  In addition,
without the consent of affected participants, no amendment of the Plan or any
award under the Plan may impair the rights of  participants under outstanding
awards.

<PAGE>   4


        (b)   Listing and Registration.  If at any time the Board shall
determine, in its discretion, that the listing, registration or qualification
of the Shares under the Plan upon any securities exchange or under any state or
Federal law, or the consent or approval of any governmental regulatory body, is
necessary or desirable as a condition of, or in connection with, the granting
of any award hereunder, no Shares may be delivered or disposed of unless such
listing, registration, qualification, consent or approval shall have been
effected or obtained free of any condition not acceptable to the Board.

        (c)  Award Agreements.    Each award of Restricted Stock and Stock
Option granted hereunder shall be evidenced by the Eligible Director's written
agreement with the Company which shall contain such terms and conditions not
inconsistent with the provisions of the Plan as shall be determined by the
Board in its discretion.

               DESCRIPTION OF THE MASCO CORPORATION PROGRAM FOR
                ESTATE, FINANCIAL PLANNING AND TAX ASSISTANCE


        In order to assure that the Company's senior executives receive the
full benefit of the Company's benefit programs given the complexities of the
tax laws relating thereto, and remain focused on Company matters, the Company
establised a program to provide senior executives with assistance in their
estate, financial planning and tax matters. Under this program, the Company
will pay up to $10,000 for such services each year, with a special
"carry-forward" of the second year's $10,000 allowance during the first year to
cover additional costs that may be associated with developing initial estate
plans. The Company will inform each participant during the course of this
process as to the amount of professional fees allocated to services performed
on such participant's behalf. The value of services received will be taxable as
ordinary income to the participant.

                       AMENDMENT TO STOCK PURCHASE AGREEMENT


        AMENDMENT dated as of May 21, 1997 between Masco Corporation, a
Delaware corporation ("Masco"), and MascoTech, Inc., a Delaware corporation

        WHEREAS, Masco and MSX are parties to a Stock Purchase Agreement, dated
as of December 23, 1991 (the "Agreement"), whereby Masco purchased from MSX the
fifty percent equity interest in Masco Capital Corporation, a Delaware
corporation ("Masco Capital"), owned by MSX;

        WHEREAS, a portion of the aggregate purchase price payable by Masco to
MSX (the "Additional Payment") under the Agreement is based on Incremental
Value, which, in turn is based on a Valuation;

        WHEREAS, pursuant to Section 10 of the Agreement, the Oversight
Committees of the Boards of Directors of Masco and MSX (the "Oversight
Committees") elected to defer payment of the Additional Payment until after a
September 30, 1996 determination of the Valuation and the Incremental Value;
and 

        WHEREAS, the Boards of Directors of each of Masco and MSX, acting with
the concurrence and  based upon the recommendations of their respective
Oversight Committees, have decided to again defer the Additional Payment until
after December 31, 1996 and to continue the authority of the Oversight
Committees in accordance with the terms of this Amendment.

        NOW, THEREFORE, the parties hereto agree as follows:

        1.    Capitalized Terms.  Unless indicated otherwise, capitalized terms
used in this Amendment shall have the same meanings ascribed to them in the
Agreement.

        2.    Determinations.  The determinations of Valuation and Incremental
Value will be made as of September 30, 1997, or such later date as the
Oversight Committees may from time to time jointly determine.

        3.    Payment.  The Additional Payment owing by Masco to MSX, if any,
shall be paid within thirty (30) days after the Oversight Committees jointly
determine the Valuation and Incremental Value.

        4.    Effect.  This Amendment shall have the effect of modifying the
Agreement, and except as modified, all of the provisions of the Agreement shall
remain in full force and effect.

        IN WITNESS WHEREOF, the parties have executed this Amendment as of the
date first written above.
