                                     PART I
 
ITEM 1. BUSINESS.
 
     MascoTech, Inc. (the "Company") is a leading supplier of metal formed
components primarily for vehicle engine and drivetrain applications and
automotive aftermarket products. In early 1998, MascoTech acquired TriMas
Corporation, in which it had held a significant equity interest since 1989.
TriMas is a diversified manufacturer of proprietary products, including
specialty fasteners, towing systems, specialty container products and other
industrial products and holds leadership positions in commercial, industrial and
consumer niche markets. The addition of TriMas' businesses, as described below,
significantly diversifies MascoTech's operations.
 
BACKGROUND
 
     MascoTech was incorporated under the laws of Delaware in 1984 as a
wholly-owned subsidiary of Masco Corporation, which in May, 1984 transferred to
MascoTech its industrial businesses. The Company became a separate public
company in July, 1984 when Masco Corporation distributed shares of Company
Common Stock as a special dividend to its stockholders. In late 1996, the
Company purchased from Masco Corporation 17 million shares of Company Common
Stock and warrants to acquire 10 million shares of Company Common Stock. Masco
Corporation currently owns approximately 17 percent of the Company's outstanding
Common Stock. Except as the context otherwise indicates, the terms "MascoTech"
and the "Company" refer to MascoTech, Inc. and its consolidated subsidiaries.
 
     Once MascoTech became a separate, publicly owned company, it pursued
diversified growth in the transportation-related, architectural and defense
markets. Structural changes in recent years in the markets served by the
Company, combined with the growth opportunities and the capital requirements of
certain of the Company's Transportation-Related businesses, led the Company to
an evaluation of the prospects for all its businesses. In late 1994, the Company
adopted a plan to dispose of its architectural products, defense and certain of
its Transportation-Related businesses. The disposition of these businesses was
completed in 1996. In addition, in 1996, the Company disposed of its heavy-gauge
stamping operations and in early 1997, the Company completed the sale of its
engineering and technical services businesses to MSX International, Inc. As part
of that transaction, the Company purchased an approximate 45 percent common
equity interest in MSX International, Inc. See "Equity Investments -- Other
Equity Investments," elsewhere in Item 1 of this Report. The disposition of
these businesses did not meet the criteria for discontinued operations treatment
for accounting purposes; accordingly, the sales and results of operations of
these businesses are included in the results of continuing operations through
the date of disposition. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Disposition of Businesses," included in
Item 7 of this Report.
 
RECENT DEVELOPMENTS
 
     In January 1998, the Company acquired the remaining 63 percent of the
outstanding shares of common stock of TriMas Corporation it did not previously
own for approximately $920 million in a transaction that will be accounted for
as a purchase. The Company's decision to acquire TriMas was designed to achieve
two primary strategic objectives: to expand its advanced metalworking process
capabilities into additional transportation-related and other diversified
industrial markets and to create additional value from affiliate investments. A
substantial portion of TriMas' industrial products are manufactured with
metalworking technologies that are complementary to MascoTech's advanced
metalworking capabilities. In addition, approximately 50 percent of TriMas'
products are sold to transportation-related markets. For further discussion of
the factors considered in making the acquisition, see "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Recent
Developments," included in Item 7 of this Report. TriMas had net sales of
approximately $668 million and net income of approximately $66 million for the
twelve months ended December 31, 1997.

     In connection with the TriMas acquisition, the Company entered into a new
$1.3 billion credit facility which is secured by a pledge of the stock of
TriMas. See the Notes to the Company's Consolidated Financial Statements
captioned "Long-Term Debt," included in Item 8 of this Report.

     Net sales include the sales of businesses held for sale or sold of $0, $412
million and $874 million in 1997, 1996 and 1995, respectively. 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.
 
(1) Amounts are before General Corporate Expense.
 
(2) 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 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 --
    $21 million and Specialty Products -- $(2) million. The remaining $(14)
    million of the net gains (charge) was allocated to General Corporate
    Expense.
 
     Sophisticated technology plays a significant role in MascoTech's businesses
and in the design, engineering and manufacturing of many of its products.
Products are manufactured utilizing a variety of metalworking and other process
technologies. Although published industry statistics are not available, the
Company believes that it is a leading independent producer of many of the
component parts that it produces using cold, warm or hot forming processes. The
Company manufactures a broad range of semi-finished components, subassemblies
and assembled products for the original equipment and aftermarket segments of
the global transportation industry. The Company provides components and products
for which reliability, quality and certainty of supply are major factors in
customers' selection of suppliers.
 
     The Company manufactures engine, drivetrain and aftermarket products.
Engine and drivetrain products include semi-finished transmission shafts, drive
gears, engine connecting rods, wheel spindles and front wheel drive components.
Aftermarket products include fuel and emission systems components, windshield
wiper blades, constant-velocity joints, brake hardware repair kits and other
automotive accessories.

     The Company's metalworked products are manufactured using various process
technologies, including cold, warm and hot forming, powdered metalworking,
value-added machining, tubular steel fabricating and hydroforming. Approximately
60 percent of the Company's 1997 sales were of products made using cold, warm or
hot metal forming technologies. The Company believes that its metalworking
technologies provide cost-competitive, high-performance, quality components
required to meet the increasing demands of the automotive and truck markets it
serves.
 
     Approximately 72 percent of the Company's 1997 sales were original
equipment automotive products and services. Sales to original equipment
manufacturers are made through factory sales personnel and independent sales
representatives. During 1997, sales to various divisions and subsidiaries of
Ford Motor Company, Chrysler Corporation, General Motors Corporation and New
Venture Gear, Inc. accounted for approximately 15 percent, 9 percent, 7 percent
and 17 percent, respectively, of the Company's net sales. Sales to the
automotive aftermarket are made primarily to distributors utilizing factory
sales personnel. Aftermarket products are sold to companies distributing into
the traditional, retail and heavy-duty segments of the automotive aftermarket.

GENERAL INFORMATION CONCERNING INDUSTRY SEGMENTS
 
     No material portion of MascoTech's business is seasonal or has special
working capital requirements. Sales by the companies which form the TriMas
Towing Systems product group are stronger during the spring and summer of the
year. The Company does not consider backlog orders to be a material factor in
its industry segments. Except as noted above under "Industry Segments," no
material portion of its business is dependent upon any one customer or 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. See, however, "Legal Proceedings,"
included as Item 3 of this Report, for a discussion of certain pending
proceedings concerning environmental matters. In general, raw materials required
by the Company are obtainable from various sources and in the quantities
desired.
 
INTERNATIONAL OPERATIONS
 
     The Company, through its subsidiaries including TriMas, has businesses
located in Australia, Canada, Czech Republic, England, Germany, Italy and
Mexico. Products manufactured by the Company outside of the United States
include forged automotive component parts, constant-velocity joints, specialty
container products and towing systems products. See the Note to the Company's
Consolidated Financial Statements captioned "Segment Information," included in

economic and other risks attendant generally to international businesses. These
risks generally vary from country to country.
 
EQUITY INVESTMENTS
 
     Information regarding the Company's equity investments is also set forth in
the Note to the Company's Consolidated Financial Statements captioned "Equity
and Other Investments in Affiliates," included in Item 8 of this Report.
 
     TriMas Corporation
 
     At December 31, 1997, the Company owned approximately 37 percent of the
outstanding common stock of TriMas Corporation. As described above, in January
1998 the Company completed the acquisition of TriMas by purchasing all of the
outstanding shares of TriMas not already owned by the Company.

                                        5
<PAGE>   7
 
and other off-highway equipment markets. Titan's sales for the year ended
December 31, 1997 were approximately $690 million.
 
     Delco Remy International, Inc.
 
     In December 1997, Delco Remy International, Inc. ("Delco Remy") completed
an initial public offering of its common stock reducing the Company's equity
ownership interest to approximately 12 percent on a fully diluted basis (the
Company owns approximately 18 percent of the voting common stock). Delco Remy is
a manufacturer of automotive electric motors and other components. Delco Remy's
sales for the year ended July 31, 1997 were approximately $690 million.
 
     Other Equity Investments
 
     In addition to its equity investments in the publicly traded affiliates
described in the preceding paragraphs, the Company has investments in privately
held companies, including MSX International, Inc., a transportation-focused
engineering and technical services company formed in 1997 by an investor group
consisting of the Company, Citicorp Venture Capital, Ltd. and senior management
of MSX International to purchase the assets of the Company's engineering and
technical services businesses. The Company also has an investment in Saturn
Electronics & Engineering, Inc., a manufacturer of electromechanical and
electronic automotive components.
 
PATENTS AND TRADEMARKS
 
     The Company holds a number of patents, patent applications, licenses,
trademarks and trade names. The Company considers its patents, patent
applications, licenses, trademarks and trade names to be valuable, but does not
believe that there is any reasonable likelihood of a loss of such rights which
would have a material adverse effect on the Company's industry segments or on
its present business as a whole.
 
COMPETITION
 
     The major domestic and foreign markets for the Company's products are
highly competitive. Competition is based primarily on price, product engineering
and performance, technology, quality and overall customer service, with the
relative importance of such factors varying among products. The Company's global
competitors include a large number of other well-established independent
manufacturers as well as certain customers who have their own internal
manufacturing capabilities. Although a number of companies of varying size
compete with the Company, no single competitor is in substantial competition
with the Company with respect to more than a few of its product lines and
services.
 
EMPLOYEES
 
     The Company employs approximately 9,000 people, which reflects the
acquisition of TriMas Corporation. Satisfactory relations have generally
prevailed between the Company and its employees.

District of California in April, 1983 by the United States of America and the
State of California against over 30 defendants, including the Company's NI
Industries, Inc. subsidiary ("NI"), for alleged release into the environment of
hazardous waste disposed of at the Stringfellow Disposal Site in California. The
plaintiffs have requested, among other things, that the defendants clean up the
contamination at that site. A consent decree has been entered into by the
plaintiffs and the defendants, including NI, providing that the consenting
parties perform partial remediation at the site. Another civil suit was filed in
the United States District Court for the Central District of California in
December, 1988 by the United States of America and the State of California
against more than 180 defendants, including NI, for alleged release into the
environment of hazardous waste disposed of at the Operating Industries, Inc.
site in California. This site served for many years as a depository for
municipal and
 
                                        7

industrial waste. The plaintiffs have requested, among other things, that the
defendants clean up the contamination at that site. Consent decrees have been
entered into by the plaintiffs and a group of the defendants, including NI,
providing that the consenting parties perform certain remedial work at the site
and reimburse the plaintiffs for certain past costs incurred by the plaintiffs
at the site. Based upon its present knowledge and subject to future legal and
factual developments, the Company does not believe that any of this litigation
will have a material adverse effect on its consolidated financial position,
results of operations or cash flow.
 
     The Company is subject to other claims and litigation in the ordinary
course of its business, but does not believe that any such claim or litigation
will have a material adverse effect on its consolidated financial position,
results of operations or cash flow.

(A) In the Third Quarter of 1997, the Company declared and paid a $.06 per share
    dividend and declared a $.06 per share dividend which was paid in the Fourth
    Quarter of 1997. The dividend declared in the Fourth Quarter of 1997 was
    paid in the First Quarter of 1998.
 
     Future declarations of dividends on the Company's Common Stock are
discretionary with the Board of Directors and will depend upon the Company's
earnings, capital requirements, financial condition and other factors. In
addition, certain of the Company's long-term debt instruments contain provisions
that restrict the dividends that it may pay on its capital stock. 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. See the discussion under "Management's
Discussion and Analysis of Financial Condition and Results of Operations --
Financial Position and Liquidity," included in Item 7 of this Report and the
Note to the Company's Consolidated Financial Statements captioned "Long-Term
Debt," included in Item 8 of this Report.
 
     On February 28, 1998, there were approximately 4,000 holders of record of
the Company's Common Stock.

</TABLE>
 
     Results in 1997 include pre-tax gains approximating $83 million principally
related to the sale by the Company of its common stock holdings of an equity
affiliate, gains from the Company's marketable securities portfolio and income
resulting from equity transactions by affiliates. These gains were partially
offset by costs and expenses of approximately $24 million pre-tax related to
plant closure costs, the Company's share of special charges recorded by equity
affiliates, write-off of deferred charges, and employee termination and other
expenses.
 
     Results for 1996 include an after-tax charge of approximately $26 million
related to the sale of MascoTech Stamping Technologies, Inc.
 
     Results for 1995 include net gains of approximately $5 million pre-tax
related to the dispositions of businesses held for sale, and a gain of
approximately $5 million pre-tax resulting from the issuance of stock through a
public offering by an equity affiliate.
 
     Results for 1994 include a pre-tax charge of $400 million, reflecting the
estimated loss on the planned disposition of a number of the Company's
businesses (see "Dispositions of Operations" note).
 
     Results for 1994 include pre-tax gains of approximately $17.9 million
related to the sale by the Company of a portion of its common stock holdings of
an equity affiliate.
 
     Results for 1993 include pre-tax income of approximately $9 million as a
result of gains associated with the sale of common stock through public
offerings by an equity affiliate. This income was largely offset by costs and
expenses related to cost-reduction initiatives, the restructuring of certain
operations and product lines, adjustments to the carrying value of certain
long-term assets, and other costs and expenses.
 
     Results for 1993 were reduced by a charge of approximately $.03 per common
share reflecting the application of the increased 1993 federal corporate income
tax rate to adjust deferred tax balances as of December 31, 1992.
 
     Income (loss) from continuing operations before accounting change and
extraordinary income (loss) attributable to common stock was $109.0 million,
$27.0 million, $46.2 million, $(247.4) million and $56.0 million after preferred
stock dividends in 1997, 1996, 1995, 1994 and 1993, respectively.
 
     At December 31, 1997, the Company adopted Statement of Financial Accounting
Standards No. 128, "Earnings Per Share." Earnings (loss) per share have been
retroactively restated to conform with the earnings per share presentation
required under SFAS No. 128.
 
     Earnings (loss) from continuing operations per common share in 1997, 1996,
1995 and 1993 are presented on a diluted basis. In 1994, basic loss per common
share is presented due to the reported loss from continuing operations. Basic
earnings per share from continuing operations were $2.70, $.54, $.85 and $1.11
in 1997, 1996, 1995 and 1993, respectively.

already owned by the Company for approximately $920 million. TriMas is a
diversified proprietary products company with leadership product positions in
commercial, industrial and consumer markets and had 1997 sales in excess of $660
million. The Company previously owned 37 percent of TriMas. The combined
companies have sales on a pro forma basis of approximately $1.6 billion for
1997.
 
     For some time, MascoTech's key strategic objectives have included the
expansion of its advanced metalworking capabilities into additional
transportation-related and other markets, and the creation of more value for its
shareholders from its affiliate investments. The acquisition of TriMas by
MascoTech is consistent with these objectives.
 
     MascoTech's advanced metalworking products are sold to
transportation-related markets, primarily for automotive light vehicle
applications. A substantial portion of TriMas' diversified industrial products
are manufactured with metalworking technologies that are complementary to
MascoTech's advanced metalworking capabilities. In addition, approximately 50
percent of TriMas' products are sold to transportation-related markets including
off-road vehicle, and aerospace, and for towing systems and accessory products,
automotive light vehicle (non-OEM), recreational vehicle, and marine markets.
The acquisition of TriMas significantly increases MascoTech's sales to
transportation-related markets and to other commercial and industrial markets
while at the same time reduces the dependence of MascoTech's operating results
on the automotive industry, which has historically been more cyclical. MascoTech
also believes that the acquisition of TriMas provides opportunities to expand
sales of certain of its products to TriMas' customers and to expand sales of
certain of TriMas' products to MascoTech's customers. In addition, the
acquisition permits MascoTech and TriMas to share research, technology and
expertise to the benefit of both companies.
 
     MascoTech reviews on an ongoing basis its various affiliate investments
with the objective of maximizing the value of these investments for its
stockholders. In analyzing its alternatives related to its investment in TriMas,
MascoTech concluded that maintaining its current level of investment in TriMas
was not an attractive alternative since MascoTech's ownership of approximately
37 percent of the TriMas shares resulted in the inclusion in MascoTech's
after-tax earnings of 37 percent of TriMas' after-tax earnings, but with
additional taxes on those earnings also accrued by MascoTech. In addition,
TriMas' dividend distributions to MascoTech represented substantially less than
37 percent of TriMas' cash flow. MascoTech also considered the alternatives of a
third party sale of its shares or the distribution to MascoTech's shareholders
of its shares to be unattractive since either transaction would have resulted in
a tax to MascoTech in excess of $180 million (valuing MascoTech's equity
interest in TriMas for this purpose at $34.50 per share which equals the
acquisition price per share).
 
     In addition to the expansion of its metalworking capabilities into
complementary markets, and the avoidance of a substantial tax that would result
from the sale or distribution of TriMas holdings, the acquisition of TriMas by
MascoTech adds high-margin complementary businesses that provide substantial
additional cash flow and human resources. MascoTech believes that the
acquisition should enhance its opportunity to create value for its shareholders
by diversifying its business mix, by improving its cost efficiencies, and by
expanding its growth opportunities.
 
     SHARE REPURCHASE
 
     The Company's major shareholder, Masco Corporation, had a long-standing
stated objective to simplify its corporate structure by reducing its affiliate
investments. More recently, Masco Corporation had committed to its shareholders
that Masco Corporation would reduce its investment in MascoTech to below 20
percent. Given the possible alternatives available to Masco Corporation to
accomplish this objective and the related uncertainty as to what action Masco
Corporation might take, together with the positive long-term outlook for
                                       11
<PAGE>   13
 
MascoTech, the MascoTech Board of Directors decided to address this issue by
proactively pursuing the purchase of Masco Corporation's holdings in MascoTech.
The MascoTech Board of Directors believed that purchasing and retiring a
substantial number of MascoTech shares (at a reasonable price) would help create
long-term value for the Company's shareholders.
 
     As a result, in late 1996, the Company purchased from Masco Corporation 17
million shares of MascoTech common stock and warrants to acquire 10 million
shares of MascoTech common stock, for approximately $266 million. As part of
this transaction, and given his role as Chairman of both Masco Corporation and
MascoTech, Richard Manoogian also agreed to sell to MascoTech one million shares
of MascoTech common stock at the then current market price of $13 5/8. As a
result, his seven percent ownership in MascoTech common stock remained
approximately the same after the share purchases. At December 31, 1997, Masco
Corporation owned approximately 17 percent of the MascoTech common stock
outstanding.
 
DISPOSITION OF BUSINESSES
 
     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
proprietary metalworking capabilities. The disposition of these businesses did
not meet the criteria for discontinued operations treatment for accounting
purposes; accordingly, the sales and results of operations of these businesses
are included in continuing operations until disposition.
 
     The Company's carrying value of a number of the businesses disposed
exceeded the estimated proceeds expected from such dispositions. To reflect the
estimated loss on the disposition of these businesses, the Company recorded a
non-cash charge in 1994 aggregating $400 million pre-tax for those businesses
for which a loss was anticipated.
 
     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). 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. 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, of which
approximately $5 million was earned in 1997, contingent upon the future earnings
of MSTI through May 31, 1999.
 
     In early 1997, the Company completed the sale of its Technical Services
Group ("TSG," 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 ("APX") which were acquired by the
Company in November 1996. The sale resulted in total proceeds to the Company of
approximately $145 million, subject to certain adjustments, consisting of cash,
subordinated debentures, preferred stock and an approximate 45 percent common
equity interest in MSX International, Inc. Net proceeds to the Company
approximated $90 million, after taking into account the purchase price for APX
and taxes payable in connection with this transaction. In January 1998, the
Company received $48 million of cash from MSX International, Inc. in payment of
certain amounts due MascoTech, resulting in a realized pre-tax gain in the first
quarter 1998 of approximately $7 million (gain recognition was deferred at the
time of the transaction pending cash receipt).
 
     Businesses sold had sales of $0, $412 million and $874 million in 1997,
1996 and 1995, respectively, and operating income (losses) before gains (charge)
on disposition of businesses, net of $0, $(13) million and $5 million in 1997,
1996 and 1995, respectively.
 
PROFIT MARGINS
 
     Operating profit margins, excluding net gains in 1997 and 1995, and net
charges in 1996, from the disposition of businesses, were approximately ten
percent in 1997, eight percent in 1996 and six percent in
 
                                       12
<PAGE>   14
 
1995. The increase in the operating profit margin in 1997 compared with the
previous two years is attributable to the disposition of businesses which had
margins lower than the Company's remaining operations.
 
CASH FLOWS AND CAPITAL EXPENDITURES
 
     Net cash flows from operating activities decreased to $79 million in 1997
from $129 million in 1996. In 1996, net cash from operating activities included
approximately $30 million in refundable income taxes.
 
     Reflecting the favorable long-term prospects for MascoTech, the Company's
Board of Directors authorized in 1994 the repurchase of 10 million shares of
Company Common Stock and Convertible Preferred Stock (converted into common
stock in 1997). Pursuant to this authorization, the Company has repurchased and
retired approximately 6.3 million shares of Company Common Stock and .5 million
shares of Convertible Preferred Stock since 1994 at a cost of approximately $90
million. In addition, in October 1996, the Company purchased and retired 18
million shares of Company Common Stock and warrants to purchase 10 million
shares of Company Common Stock for cash and notes approximating $280 million
(see "Corporate Development" above and "Shareholders' Equity" note to the
financial statements).
 
     The Company in 1997 increased the quarterly dividend on its common stock to
$.06 per share from $.05.
 
     Capital expenditures in 1997 were approximately $55 million as compared
with $44 million and $110 million in 1996 and 1995, respectively. During 1995,
the Company made significant expenditures in capital programs to support the
Company's metalworking and aftermarket businesses. These expenditures for new
advanced manufacturing technologies, product line extensions and capacity for
new products were the result of the Company's favorable long-term outlook for
these businesses and to meet increased demand for certain product programs.
 
INVENTORIES
 
     The Company's investment in inventories for its businesses increased
modestly to approximately $74 million at December 31, 1997 as compared with $70
million in 1996. The Company's continued emphasis on inventory management,
utilizing Just-In-Time and other inventory management techniques, has
contributed to higher inventory turnover rates in recent years.
 
FINANCIAL POSITION AND LIQUIDITY
 
     In connection with the TriMas acquisition in January 1998, the Company
entered into a new $1.3 billion credit facility. On a pro forma basis at
December 31, 1997 including the borrowings for the TriMas acquisition, debt as a
percent of total debt plus equity would be approximately 87 percent. The
Company's new credit facility includes a $500 million term loan and an $800
million revolver, both of which terminate in 2003. 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. In addition, future cash dividends and any
acquisition of Company Common Stock could be further accomplished with internal
cash flows from operations.
 
     Although the Company incurred increased debt with the purchase of TriMas,
the Company's interest coverage ratio and debt to cash flow ratio remain strong.
The Company expects that its ratio of debt to total debt plus equity will
improve from the operating performance of its businesses and from the
disposition of certain financial assets. The Company's financial assets include
equity ownership positions in two additional publicly traded companies with an
aggregate carrying value of approximately $53 million. This compares with an
aggregate quoted market value at December 31, 1997 (which may differ from the
amounts that could have been realized upon disposition) of approximately $104
million. On September 30, 1997, the Company
 
                                       13
<PAGE>   15
 
exercised its option and exchanged its equity holdings in Emco Limited and
approximately $46 million in cash to Masco Corporation to satisfy the
indebtedness to Masco incurred in 1996 in connection with the Company's purchase
and retirement of certain of its common shares and warrants held by Masco.
 
     At December 31, 1997 current assets, which aggregated approximately $336
million, were approximately two times current liabilities. Additional borrowings
available under the Company's new revolving credit agreement and otherwise,
anticipated internal cash flows, and to the extent necessary, future financings
in the financial markets are expected to provide sufficient liquidity to fund
the Company's foreseeable working capital, capital expansion programs and other
investment needs.
 
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 problem 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
preliminary information, costs of addressing potential problems are not
currently expected to have a material adverse impact on the Company's financial
position, results of operations or cash flows in future periods. However, if the
Company, its customers or vendors are unable to resolve such processing issues
in a timely manner, the failure to do so could result in a material financial
risk. Accordingly, the Company is devoting the resources believed to be
necessary to resolve all significant year 2000 issues in a timely manner.
 
     The Company's corporate services agreement with Masco Corporation expires
September 30, 1998. Negotiations have commenced to determine the scope of any
services to be acquired in the future and the cost of such services. It is
expected that a new agreement will be executed prior to September 30, 1998.
 
GENERAL FINANCIAL ANALYSIS
 
1997 VERSUS 1996
 
     Sales of the Company's metalworking and aftermarket businesses increased
six percent to approximately $922 million from $869 million in 1996. Total sales
for 1997, however, declined to approximately $922 million from $1.3 billion in
1996, reflecting the previously announced disposition of certain businesses.
 
     Income after preferred stock dividends in 1997 was $109 million or $2.12
per common share. Results in 1997 include pre-tax gains approximating $83
million principally related to the disposition of the Company's equity ownership
interest in Emco Limited, gains from the Company's marketable securities
portfolio and income resulting from equity transactions by affiliates. These
gains were partially offset by costs and expenses of approximately $24 million
pre-tax related to plant closure costs, the Company's share of special charges
recorded by equity affiliates, write-off of deferred charges, and employee
termination and other expenses. Excluding the gains and unusual costs, income
after preferred stock dividends in 1997 would have been approximately $73
million, or $1.50 per common share.
 
     Income after preferred stock dividends in 1996 was $38.7 million or $.72
per common share. Results in 1996 include an after-tax loss of approximately $26
million related to the sale of the Company's heavy-gauge stamping operations
(MSTI), which more than offset after-tax income of approximately $11.7 million
related to the cumulative effect of an accounting change. Excluding the above
items, income in 1996 after preferred stock dividends would have been
approximately $53 million or $.98 per common share.
 
     Operating profit in 1997 for the Company's metalworking and aftermarket
businesses, before general corporate expense, decreased to approximately $119
million from $136 million in 1996. Although 1997 results benefitted from
increased sales in the Company's transportation-related businesses, operating
performance was negatively impacted by work stoppages at certain North American
vehicle manufacturers, costs and expenses as a result of a strike at one of the
Company's manufacturing facilities and higher than anticipated product start-up
costs. Businesses sold had operating losses before general corporate expense and
gains (charge) on disposition of businesses, net of approximately $13 million
for 1996.
                                       14
<PAGE>   16
 
     In late 1996, the Company announced the planned sale of the Company's
Technical Services Group. Net assets of businesses held for sale decreased by
approximately $109 million during 1997 as a result of the sale which occurred on
January 3, 1997.
 
     Other income (expense), net in 1997, was income of approximately $89
million as compared with income of approximately $8 million in 1996. Results for
1997 benefitted from a gain on the disposition of an equity affiliate, gains
from the Company's marketable securities portfolio, higher equity and interest
income from affiliates and income resulting from equity transactions by
affiliates. This income was partially offset by higher interest expense in 1997.
 
1996 VERSUS 1995
 
     Sales of the Company's metalworking and aftermarket businesses increased
eight percent from 1995 to approximately $869 million, while sales of the
Company's businesses held for sale or sold decreased approximately 53 percent
from the comparable period in 1995 as a result of the disposition of a number of
such businesses. Sales for 1996 declined to $1.3 billion from $1.7 billion in
1995, reflecting the previously announced disposition of certain businesses.
 
     Income after preferred stock dividends in 1996 was $38.7 million or $.72
per common share. Results in 1996 include an after-tax loss of approximately $26
million related to the sale of the Company's heavy-gauge stamping operations
(MSTI) which more than offset after-tax income of approximately $11.7 million
related to the cumulative effect of an accounting change. Income after preferred
stock dividends in 1995 was $46.2 million or $.81 per common share.
 
     Operating profit in 1996 for the metalworking and aftermarket businesses,
before general corporate expense, increased to approximately $136 million from
$116 million in 1995, resulting from increased volume and the reduction of
launch and start-up costs and expenses related to the Company's capital
expansion programs. Businesses held for sale or sold (including MSTI and TSG)
had operating income (losses) before general corporate expense and gains
(charge) on disposition of businesses, net of approximately $(13) million and $5
million for 1996 and 1995, respectively.
 
     In December 1994, the Company announced the planned disposition of 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. During 1995 and 1996, the Company completed the disposition of
such businesses for proceeds aggregating approximately $400 million. Net assets
of businesses held for sale decreased by approximately $167 million during 1996
as a result of the disposition of such businesses and from the reduction of
assets employed in these businesses through operating activity, asset sales and
the redeployment of certain assets. Net assets of businesses held for sale at
December 31, 1996 reflect the net assets of the Company's Technical Services
Group and APX International which were sold January 3, 1997.
 
     In 1995, the Company sold businesses in transactions which resulted in net
gains of approximately $25 million. These net gains were substantially offset by
reductions in the estimated net proceeds that the Company expected to receive
from certain businesses remaining to be sold, aggregating approximately $12
million, and by certain exit costs related to the businesses sold or held for
sale incurred in 1995 aggregating approximately $8 million.
 
     Other income (expense), net in 1996, was income of approximately $8 million
as compared with expense of approximately $9 million in 1995. Results for 1996
benefitted from reduced interest expense as proceeds from the disposition of
businesses were applied to reduce the Company's indebtedness as well as from
increased earnings from equity affiliates. Results for 1995 were impacted by
pre-tax income of approximately $5 million as a result of gains associated with
the sale of common stock through a public offering by an equity affiliate.
 
     The Company's 1996 effective tax rate differs from the statutory rate
principally because a significant portion of the loss on the sale of the
heavy-gauge stamping operations does not result in a tax benefit.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA.
 
                       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)(i) 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 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,
approximately $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.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     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, had sales
of $0, $412 million and $874 million in 1997, 1996 and 1995, respectively, and
operating income (losses) before gains (charge) on disposition of businesses,
net of $0, $(13) million and $5 million in 1997, 1996 and 1995, respectively.

     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.

     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

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):

     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.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     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.

</TABLE>
 
     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.

     Postretirement Benefits. The Company provides postretirement medical and
life insurance benefits for certain of its active and retired employees.
 
     The Company records its postretirement benefit plans in accordance with
Statement of Financial Accounting Standards No. 106 ("SFAS No. 106"),
"Employers' Accounting for Postretirement Benefits Other Than Pensions." This
statement requires the accrual method of accounting for postretirement health
care and life insurance based on actuarially determined costs to be recognized
over the period from the date of hire to the full eligibility date of employees
who are expected to qualify for such benefits. In conjunction with SFAS No. 106,
the Company recognizes the transition obligation on a prospective basis with the

     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.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
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.
 
     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:

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors
of MascoTech, Inc.:
 
     We have audited the consolidated balance sheet of TriMas Corporation 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 as listed in Item 14(a)(2)(ii) of this Form 10-K. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements 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 TriMas
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.
 
     As discussed in Note 2 to the financial statements, substantially all the
outstanding shares of the Company not already owned by MascoTech, Inc. were
acquired by them in January 1998. The Company is now a wholly owned subsidiary
of MascoTech, Inc.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1. ACCOUNTING POLICIES
 
PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of TriMas
Corporation and its wholly owned subsidiaries (the "Company"). All significant
intercompany transactions have been eliminated.
 
ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make 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 those estimates.
 
AFFILIATES
 
     As of December 31, 1997 MascoTech, Inc.'s common stock ownership in the
Company approximated 36.8 percent (see "Subsequent Event" note), and Masco
Corporation's common stock ownership approximated 3.8 percent. The Company has a
corporate services agreement with Masco Corporation. Under the terms of the
agreement, the Company pays a fee to Masco Corporation for various corporate
support staff, administrative services, and research and development services.
Such fee equals .8 percent of the Company's net sales, subject to certain
adjustments, and totaled $4.0 million, $3.3 million and $3.1 million in 1997,
1996 and 1995.
 
CASH AND CASH EQUIVALENTS
 
     The Company considers all highly liquid debt instruments purchased with a
maturity of three months or less to be cash equivalents. At December 31, 1997
the Company had $81.4 million invested in prime commercial paper of several
United States issuers having the highest rating given by one of the two
principal rating agencies.
 
RECEIVABLES
 
     Receivables are presented net of an allowance for doubtful accounts of $2.0
million and $1.9 million at December 31, 1997 and 1996.
 
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
 
     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. 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 1/2 to 5 percent, and machinery and
equipment, 6 2/3 to 33 1/3 percent. The excess of cost over net assets of
acquired companies is

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 1. ACCOUNTING POLICIES (CONTINUED)
being amortized using the straight-line method over the periods estimated to be
benefited, not exceeding 40 years. At December 31, 1997 and 1996, accumulated
amortization of the excess of cost over net assets of acquired companies and
other intangible assets was $42.7 million and $36.6 million. Amortization
expense was $6.1 million, $5.3 million and $5.0 million in 1997, 1996 and 1995.
 
     As of each balance sheet date management assesses whether there has been an
impairment in the value of excess of cost over net assets of acquired companies
by comparing anticipated undiscounted future cash flows from the related
operating activities with the carrying value. The factors considered by
management in performing this assessment include current operating results,
trends and prospects, as well as the effects of obsolescence, demand,
competition and other economic factors. Based on this assessment there was no
impairment at December 31, 1997.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying values of financial instruments classified in the balance
sheet as current assets and current liabilities approximate fair values. The
fair value of notes receivable, a portion of which is included in both
receivables and other assets, based on discounted cash flows using current
interest rates, approximates the carrying value of $7.8 million at December 31,
1997.
 
     The carrying amount of borrowings from banks approximates fair value as the
floating rates applicable to this debt generally reflect changes in overall
market interest rates.
 
FOREIGN CURRENCY TRANSLATION
 
     Net assets of the Company's operations outside of the United States are
translated into U.S. dollars using current exchange rates with the effects of
translation adjustments deferred and included as a separate component of
shareholders' equity. Revenues, expenses and cash flows are translated at the
average rates of exchange during the period.
 
NOTE 2. SUBSEQUENT EVENT
 
     On December 17, 1997 MascoTech Inc.("MascoTech"), through its wholly owned
subsidiary MascoTech Acquisition, Inc.("MascoTech Acquisition"), commenced a
tender offer to acquire all of the outstanding shares of the Company not already
owned by MascoTech. The tender offer was made in accordance with the terms of a
merger agreement between the Company, MascoTech and MascoTech Acquisition. The
tender offer expired on January 16, 1998 after approximately 95 percent of the
Company's outstanding shares not owned by MascoTech had been tendered. On
January 22, 1998 MascoTech Acquisition made payment on the tendered shares and
was merged with and into the Company, with the Company surviving as a private
and wholly owned subsidiary of MascoTech. During 1997 the Company recognized a
$5.0 million (pre-tax and after tax) extraordinary charge related to the
expenses incurred in connection with this going private transaction.

NOTE 3. ACQUISITIONS
 
     During 1996 the Company acquired Queensland Towbars Pty. Ltd., The Englass
Group Limited, Heinrich Stolz GmbH and Beaumont Bolt & Gasket Co., all for an
aggregate $54.2 million of cash and assumed liabilities. The acquisitions were
accounted for as purchases. The aggregate excess of cost over net assets
acquired of $28.8 million is being amortized on a straight-line basis over 40
years. The results of operations of the acquired businesses have been included
in the consolidated financial statements from the respective acquisition dates.
 
     During 1997 the Company paid $11.3 million to the former owners of
businesses acquired in previous years, including $7.0 million to MascoTech, Inc.
These payments resulted from the acquired businesses having achieved specified
levels of profitability during designated periods subsequent to the acquisition.
These payments were recorded as additional excess of cost over net assets of
acquired companies and are being amortized over the remainder of the original 40
year amortization period.

rates on the London Interbank Offered Rate (LIBOR). At December 31, 1997 the
blended interest rate on bank borrowings equaled 6.4 percent. The facilities
contain certain restrictive covenants, the most restrictive of which, at
December 31, 1997, required $381.5 million of shareholders' equity. The Company
had available credit of $8.6 million under its foreign revolving credit

NOTE 10. STOCK OPTIONS AND AWARDS
 
     The Company's stock incentive plans include the TriMas Corporation 1995
Long Term Stock Incentive Plan, the 1988 Restricted Stock Incentive Plan and the
1988 Stock Option Plan. Company common stock available for grant under these
plans includes the 2,000,000 shares initially established under the 1995 plan,
plus additional shares resulting from certain reacquisitions of shares by the
Company.
 
     The Company granted long-term incentive awards of Company common stock,
net, for 64,815 shares in 1997, 159,071 shares in 1996 and 290,588 shares in
1995, to key employees of the Company. The weighted average fair value per
share, on date of grant, of long-term incentive awards granted in 1997, 1996 and
1995 was $24.15, $19.66 and $23.21. Compensation expense recorded in 1997, 1996
and 1995 related to long-term incentive awards was $2.4 million, $2.2 million
and $1.6 million. The unamortized costs of incentive awards, aggregating $13.2
million at December 31, 1997, are being amortized over the vesting periods,
which are typically ten years.
 
     Fixed stock options are granted to key employees of the Company and have a
maximum term of ten years. The exercise price of each fixed option equals the
market price of the Company's common stock on the date of grant. The options
generally vest in installments beginning in the second year and extending
through the eighth year after grant. For the three years ended December 31, 1997
stock option information is as follows:

     The Company applies Accounting Principles Board Opinion No. 25, Accounting
for Stock Issued to Employees, in accounting for stock based compensation.
Accordingly, no compensation expense has been charged against income for fixed
stock option grants. Had compensation expense been determined based on the fair
value at the 1997, 1996 and 1995 grant dates, consistent with the methodology of
Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based
Compensation, the pro forma effect on the Company's net income would not have
been material.
 
     At December 31, 1997 and 1996, a combined total of 1,952,669 and 2,011,642
shares of Company common stock were available for the granting of options and
incentive awards under the aforementioned plans.

     Contributions to profit-sharing and other defined contribution plans are
generally determined as a percentage of the covered employee's annual salary.
 
     Defined benefit plans provide retirement benefits for salaried employees
based primarily on years of service and average earnings for the five highest
consecutive years of compensation. Defined benefit plans covering hourly
employees generally provide benefits of stated amounts for each year of service.
These plans are funded based on an actuarial evaluation and review of the
assets, liabilities and requirements of each plan. Plan assets are held by a
trustee and invested principally in cash equivalents and marketable equity and
fixed income instruments.
 
     Net periodic pension cost of defined benefit plans includes the following

     The Company provides postretirement health care and life insurance benefits
for certain eligible retired employees under unfunded plans. Some of the plans
have cost-sharing provisions. Net periodic postretirement benefit costs during
1997, 1996 and 1995 were $1.0 million, $1.0 million and $.8 million.
 
     The aggregate accumulated postretirement benefit obligation of these
unfunded plans was $4.4 million and $7.1 million at December 31, 1997 and 1996.
The discount rates used in determining the accumulated postretirement benefit
obligations and the net periodic postretirement benefit costs were 7.25 percent,
7.5 percent and 7.25 percent in 1997, 1996 and 1995. The assumed health care
cost trend rate in 1997 was nine percent, decreasing to an ultimate rate in the
years subsequent to 2006 of five percent. A one percent increase in the assumed
health care cost trend rates would have increased the net periodic
postretirement benefit cost by $.1 million during 1997 and would have increased
the accumulated postretirement benefit obligation at December 31, 1997 by $.5
million. The Company is amortizing the unrecognized transition accumulated
postretirement benefit obligation and subsequent plan net gains and losses in
accordance with Statement of Financial Accounting Standards No. 106. The accrued
postretirement benefit obligation was $4.1 million and $3.5 million at December
31, 1997 and 1996.

                      RESTATED CERTIFICATE OF INCORPORATION

                                       OF
                             MASCO INDUSTRIES, INC.

                                    * * * * *

     MASCO INDUSTRIES, INC., a corporation organized and existing under the Laws
of the State of Delaware (the "Company"), hereby certifies as follows:

     FIRST: The name of the Company is MASCO INDUSTRIES, INC. The date of filing
its original Certificate of Incorporation with the Secretary of State was March
15, 1984.

     SECOND: 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.

     THIRD: 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:

     1.   The name of the corporation is:
                    MASCO INDUSTRIES, INC.

     2.   The address of its registered office in the State of Delaware is
Corporation Trust Center, 1209 Orange Street, in the City of Wilmington, County
of New Castle. The name of its registered agent at such address is The
Corporation Trust Company.

     3.   The nature of the business or purpose to be conducted or promoted is 
to engage in any lawful act or activity for which corporations may be organized
under the General Corporation Law of Delaware.

<PAGE>   2

     4.   The total number of shares of stock the corporation shall have 
authority to issue is two hundred seventy-five million (275,000,000) shares.

     Two hundred fifty million (250,000,000) of such shares shall consist of
common shares, par value one dollar ($1.00) per share, and twenty-five million
(25,000,000) 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 Company, whether voluntary or involuntary, the holders of
     the preferred stock shall be entitled, before any assets of the Company
     shall be distributed among or paid over to the holders of the common stock,
     to an amount per share to be determined before issuance 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 Company. After the making of
     such payments to the holders of the preferred stock, the remaining assets
     of the Company 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 Company
     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 

                                     - 2 -

<PAGE>   3


     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 Company; (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 Company, if such shares are to be convertible.

          C.   No holder of any class of stock issued by this Company shall be
     entitled to pre-emptive rights.

          D.   The number of authorized shares of each class of stock may be
     increased or decreased (but not below the number of shares thereof then
     outstanding) by the affirmative vote of the holders of a majority of the
     stock of the Company entitled to vote, voting together as a single class.

     5.   (a)  The business and affairs of the Company 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 

                                      - 3 -

<PAGE>   4
Directors that results from an increase in the number of directors shall be
filled only by a majority of the Board of Directors then 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
Company 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 respect to such
stock, such directors so elected shall not be divided into classes pursuant to
this Article 5, 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 5, 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

of the Company entitled to vote in elections of


                                      - 6 -



<PAGE>   7
 
directors, considered for the purposes of this Article 12 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 Company
entitled to vote in elections of directors considered for the purposes of this
Article 12 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 Company in such business
     combination bears the same or a greater percentage relationship to the
     market price of the Company'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 Company's
     common stock already owned by it bears to the market price of the common
     stock of the Company immediately prior to the commencement of acquisition
     of the Company'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 Company 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 Company's common stock, and
     (ii) is not less than the earnings per share of common stock of the Company
     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 Company's Board of Directors included
     at all times representation by continuing director(s) (as hereinafter
     defined) proportionate to the stockholdings of the Company'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
     Company's common stock except as necessary to insure that a quarterly
     dividend payment does not exceed 5% of the net income of the Company for
     the four full consecutive fiscal quarters immediately preceding the
     declaration date of such dividend, 

                                     - 7 -

     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 Company (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 Company'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 assistance or tax
     credits of or provided by the Company, or (ii) made any major change in the
     Company'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

          (e)  A proxy statement responsive to the requirements of the United
     States securities laws shall be mailed to all common stockholders of the
     Company for the purpose of soliciting stockholder approval of such business
     combination and shall contain on its first page thereof, in a 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 Company (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 Company
     upon receipt of such opinion).

     The provisions of this Article 12 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 the outstanding shares of stock of
the Company entitled to vote in elections of directors considered for the
purposes of this Article 12 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 the
business combination, such other entity is an "affiliate" of the Company (as
hereinafter defined).

     B.   As used in this Article 12, (a) the term "other entity" shall include
any corporation, person or other entity and any other entity with which it or
its "affiliate" or "associate" (as defined 


                                      - 8 -

<PAGE>   9

below) has any agreement, arrangement or understanding, directly or indirectly,
for the purpose of acquiring, holding, voting or disposing of stock of the
Company, or which is its "affiliate" or "associate" as those terms are defined
in Rule 12b-2 of the General Rules and Regulations under the Securities Exchange
Act of 1934 as in effect on March 31, 1984, together with the successors and
assigns of such persons in any transaction or series of transactions not
involving a public offering of the Company's stock within the meaning of the
Securities Act of 1933; provided, however, that an "other entity" shall not in
any event include any entity owning 30% or more of the outstanding shares of
stock of the Company entitled to vote in the elections of directors considered
for purposes of this Article 12 as one class at the time of the adoption of this
Article 12, any subsidiary of such entity, or any corporation succeeding to the
business of such entity if (i) such business as conducted immediately prior to
such succession is, immediately after such succession, the sole business of such
successor, and (ii) the stockholders of the corporation conducting such business
immediately prior to such succession are, immediately after such succession, the
sole stockholders of the successor corporation or of a corporation owning all of
the capital stock of such successor corporation; (b) an other entity shall be
deemed to be the beneficial owner of any shares of stock of the Company which
the other entity (as defined above) has the right to acquire pursuant to 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 Company 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 Company with or into any other entity, or the
sale or lease of all or any substantial part of the assets of the Company to, or
any sale or lease to the Company or any subsidiary thereof in exchange for
securities of the Company of any assets (except assets having an aggregate fair
market value of less than $5,000,000) of, any other entity; (e) the term
"continuing director" shall mean a person who was a member of the Board of
Directors of the Company elected by stockholders prior to the time that such
other entity acquired in excess of 10% of the stock of the Company entitled to
vote in the election of directors, or a person recommended to succeed a
continuing director by a majority of continuing directors; and (f) for the
purposes of subparagraphs A(a) and (b) of this Article 12 the term "other
consideration to be received" shall mean, in addition to other consideration
received, if any, capital stock of the Company retained by its existing public
stockholders in the event of a business combination with such other entity in
which the Company is the surviving corporation; and (g) the exclusion of an
entity from constituting an "other entity" under subparagraph B(a) of this
Article 12 shall only continue to be effective if such entity does not
thereafter decrease such 

                                     - 9 -

<PAGE>   10
ownership percentage to less than 30% (other than through the Company's issuance
of its capital stock) and subsequently reacquire such a 30% interest and
provided that, upon any such decrease and subsequent reacquisition, such entity
shall be deemed for purposes of this Article 12 to have first become an "other
entity" and to first have acquired capital stock of the Company on the date of
such reacquisition.

     C.   A majority of the continuing directors shall have the power and duty 
to determine for the purposes of this Article 12 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 Company 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, arrangement or
understanding with another; or (d) the assets being acquired by the Company, or
any subsidiary thereof, have an aggregate fair market value of less than
$5,000,000.

     D.   No amendment to the Certificate of Incorporation of the Company shall
amend or repeal any of the provisions of this Article 12, 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 12 as one
class; provided that this paragraph D 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 Company if all of such
directors are persons who would be eligible to serve as "continuing directors"
within the meaning of paragraph B of this Article 12.

     E.   Nothing contained in this Article 12 shall be construed to relieve any
other entity from any fiduciary obligation imposed by law.

     13.  A director of the Company shall not be personally liable to the 
Company 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 Company 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 Company, 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 13 shall not increase the liability of any director of the Company
for any act or occurrence taking place 
        

                                     - 10 -

<PAGE>   11
prior to such repeal or modification, or otherwise adversely affect any right or
protection of a director of the Company existing at the time of such repeal or
modification.

     14.  A.   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 a director, officer or employee of the Company,
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
Company 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 Company to provide
broader indemnification rights than such law permitted the company 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 Company 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 A shall be a
contract right and shall include the right to be paid by the Company 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 Company 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 14 or otherwise.

      B.  The Company 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 Company and to any person who is or was serving at the request
of the Company 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 

                                     - 11 -

<PAGE>   12
to be appropriate and permitted by applicable law, as the same exists or may
hereafter be amended.

     C.   The rights to indemnification and to the advancement of expenses
conferred in this Article 14 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 bylaws of the Company, agreement, vote of
stockholders or disinterested directors or otherwise.

the Company upon shares of this Series or Parity Shares shall be declared pro
rate with respect to all shares of this Series and all Parity Shares then
outstanding, so that the amounts of any dividends declared on shares of this
Series and such Parity Shares shall in all cases bear to each other the same
ratio that, at the time of such declaration, all accrued and payable but unpaid
dividends on shares of this Series and such Parity Shares, respectively, bear to
each other.

     (iii) Optional Redemptions for Cash. Subject to the restrictions in Clause
(ii) above, shares of this Series shall be redeemable at the option of the
Company in whole or from time to time in part, on any April 1, July 1, October 1
or January 1, commencing April 1, 1991 in cash at $100 per share, plus an amount
equal to the dividends accrued and unpaid thereon to the redemption date.

     Not less than 30 nor more than 60 days prior to the date fixed for any
redemption of shares of this Series pursuant to this Clause (iii), a notice
shall be given by first class mail, postage prepaid, to the holders of record of
the shares of this Series to be redeemed at their respective addresses as the
same shall appear on the books of the Company, specifying the certificate
numbers of such shares, the effective date of the redemption and the place where
certificates for shares of this Series are to be surrendered for redemption and.
stating that dividends on such shares of this Series will cease to accrue on and
after the redemption date, but neither failure to mail such notice, nor any
defect therein or in the mailing thereof, to any particular holder shall affect
the sufficiency of the notice or the validity of the proceedings for redemption
with respect to the other holders. Any notice which was mailed in the manner
herein provided shall be conclusively presumed to have been duly given whether
or not the holder receives the notice.

     If notice of redemption has been given pursuant to this Clause (iii) and
if, on or before the date fixed for redemption, the funds necessary for such
redemption shall have been set aside by the Company, separate and apart from its
other funds, in trust for the pro rata benefit of the holders of the shares so
called for redemption, then on and after the redemption date, notwithstanding
that any certificates for such shares have not been surrendered for
cancellation, dividends shall cease to accrue on the shares of this Series to be
redeemed and the holders of such shares shall cease to be stockholders with
respect to such shares and shall have no interest in or claims against the
Company by virtue thereof and shall have no voting or other rights with respect
to such shares, except the right to receive the moneys payable upon such
redemption, without interest thereon, upon surrender (and endorsement, if
required by the Company) of their certificates, and the shares evidenced thereby
shall no longer be outstanding. Subject to applicable escheat laws, any moneys
so set aside by the Company and unclaimed at the end of one year from the
redemption date shall revert to the general funds of the Company after which
reversion the holders of such shares so called for redemption shall look only to
the general funds of the Company for the payment of the redemption price. Any
interest accrued on funds so deposited shall be paid to the Company from time to
tome. Any holder of record of the shares of this Series to be redeemed pursuant
to this Clause (iii) may waive its right to notice hereunder.

     In every case of redemption of less than all of the outstanding shares of
this Series pursuant to this Clause (iii), the shares to be redeemed shall be
selected (a) by lot or by such other manner as may be prescribed by resolution
of the Board of Directors of the Company and (b) in accordance with the Exchange
Agreement as amended from time to time (the "Exchange Agreement") dated as of
December 18, 1990 between the Company and Masco Corporation, a Delaware
corporation ("Masco"), a copy of which Exchange Agreement

                                      - 3 -

<PAGE>   17

shall be kept on file with the Secretary of the Company, provided that only
whole shares shall be selected for redemption.

     (iv) Optional Redemption through Debenture Exchange.

     (a)  Subject to the restrictions in subclauses (b) and (d) of this Clause
(iv), shares of this Series shall be redeemable at the option of the Company, in
whole or from time to time in part, on any April 1, July 1, October 1 or April
1, commencing April 1, 1991 through the issuance, in redemption of and in
exchange for shares of this Series, of the Company's Junior Subordinated
Debentures Due 2006 (hereinafter referred to as the "Junior Debentures") in the
manner provided in this Clause (iv). The Junior Debentures shall be issued in
substantially the form of Exhibit B to the Exchange Agreement subject to any
changes that may be made to such Junior Debentures pursuant to the Exchange
Agreement to qualify an indenture with respect to such Junior Debentures. The
Junior Debentures shall be issued in series with the interest rate on such
series being a rate per annum that is the lower of 12% or 400 basis points over
the Treasury Rate (as hereinafter defined) for the week preceding the week in
which the notice of redemption and exchange is given to holders of shares of
this Series as provided in subclause (iv)(c) below. "Treasury Rate" means, the
rate for direct obligations of the United States ("Treasury Notes") having a 10-
year maturity, as published in the Federal Reserve Statistical Release H.15(519)
(or any successor publication provided by the Board of Governors of the Federal
Reserve Board) under the heading "Treasury Constant Maturities." In the event
that a rate for Treasury Notes having a 10-year maturity is not published or
reported for the prior week as provided above by 1:00 p.m., New York City time,
on the third business day preceding the day such notice of redemption and
exchange is given to such holders, then the Treasury Rate shall be calculated by
the Company and shall be a yield to maturity (expressed as a bond equivalent, on
the basis of a year of 365 or 366 days, as applicable, and applied on a daily
basis) of the arithmetic mean of the secondary market bid rates, as of
approximately 1:30 P.M., New York City time, on the date of such notice of
redemption and exchange, of three leading primary United States government
securities dealers selected by the Company for the issue of Treasury Notes with
a remaining maturity of 10 years.

     (b)  The Junior Debentures will be issued solely in redemption of and in
exchange for shares of this Series at the rate of $100 principal amount of
Junior Debentures for each share of this Series redeemed and exchanged on the
applicable Exchange Date (as defined below). An amount equal to all accrued but
unpaid dividends on such shares to the dividend payment date which coincides
with the date of redemption and exchange shall be paid in cash on the date of
such redemption and exchange. No redemption and exchange shall be for an
aggregate principal amount of Junior Debentures less than $5 million, and no
Junior Debentures in amounts other than $1,000 (and integral multiples thereof)
shall be issued in any redemption

                                      - 4 -

<PAGE>   18

and exchange. Cash will be paid in lieu of any such fraction of a Junior
Debenture which would otherwise have been issued.

     (c)  Not less than 30 nor more than 60 days prior to the date fixed for the
issue of Junior Debentures in redemption of and in exchange for shares of this
Series pursuant to this Clause (iv), a notice shall be given by first class
mail, postage prepaid, to the holders of record of the shares of this Series to
be redeemed and exchanged at their respective addresses as the same shall appear
on the books of the Company, specifying the certificate numbers of such shares,
the effective date of the redemption and exchange (the "Exchange Date") and the
place where certificates for shares of this Series are to be surrendered for
Junior Debentures and stating that dividends on such shares of this Series will
cease to accrue on and after the Exchange Date, but neither failure to mail such
notice, nor any defect therein or in the mailing thereof, to any particular
holder shall affect the sufficiency of the notice or the validity of the
proceedings for redemption and exchange with respect to the other holders. Any
notice which was mailed in the manner herein provided shall be conclusively
presumed to have been duly given whether or not the holder receives the notice.
Any holder of record of the shares of this Series to be redeemed and exchanged
pursuant to this Clause (iv) may waive its right to notice hereunder.

     If notice of redemption and exchange has been given pursuant to this Clause
(iv), then on or after the Exchange Date (unless the Company shall default in
issuing Junior Debentures in redemption of and in exchange for shares of this
Series to be redeemed and exchanged on such Exchange Date or shall fail to pay
or set aside accrued and unpaid dividends on such shares of this Series and
notwithstanding that any certificates for such shares of this Series have not
been surrendered for exchange), dividends shall cease to accrue on such shares
of this Series and the holders of such shares shall cease to be stockholders
with respect to such shares (provided, that the persons entitled to receive
Junior Debentures in exchange for such shares shall be treated for all purposes
as the registered holders of such Junior Debentures) and shall have no interest
in or claims against the Company by virtue thereof (except the right to receive
Junior Debentures) and shall have no voting or other rights with respect to such
shares and such shares of this Series shall no longer be outstanding. Upon the
surrender (and endorsement, if required by the Company) in accordance with such
notice of the certificates for such shares of this Series, such certificates
shall be redeemed and exchanged for Junior Debentures in accordance with this
Clause (iv).

     (d)  The Company may not redeem and exchange less than all shares of this
Series (1) if, at the time of such redemption and exchange, there are accrued
and unpaid dividends on any shares of this Series and (2) unless, immediately
after such redemption and exchange, at least 50,000 shares of this Series will
be outstand-

                                      - 5 -

<PAGE>   19

ing. In every case of redemption of less than all of the outstanding shares of
this Series pursuant to this Clause (iv), the shares shall be selected (a) by
lot or by such other manner as may be prescribed by resolution of the Board of
Directors of the Company and (b) in accordance with the Exchange Agreement,
provided that only whole shares shall be selected for redemption.

     (v)  Liquidation.

     (a)  The liquidation price of shares of this Series, in case of the
voluntary or involuntary liquidation, dissolution or winding-up of the Company,
shall be $100 per share, plus the amount per share of any dividends accrued
thereon and remaining unpaid at the date of such liquidation, dissolution or
winding-up.

     (b)  In the event of any voluntary or involuntary liquidation, dissolution
or winding-up of the Company, the holders of shares of this Series shall be
entitled to receive the liquidation price of such shares held by them in
preference to and in priority over any distributions upon the Common Shares and
all Junior Shares, but subject to the rights of holders of Preference Shares
having a preference to and priority over the payment of distributions on the
shares of this Series. Upon payment in full of the liquidation price to which
the holders of shares of this Series are entitled, the holders of shares of this
Series will not be entitled to any further participation in any distribution of
assets by the Company. If the assets of the Company are not sufficient to pay in
full the liquidation price payable to the holders of shares of this Series and
the liquidation price payable to the holders of all Parity Shares, the holders
of all such shares shall share ratably in such distribution of assets in
accordance with the amounts which would be payable on such distribution if the
amounts to which the holders of shares of this Series and the holders of Parity
Shares are entitled were paid in full.

     (c)  Neither a consolidation or merger of the Company with or into any
other corporation, nor a merger of any other corporation with or into the
Company, nor a sale or transfer of all or any part of the Company's assets for
cash, securities or other property shall be considered a liquidation,
dissolution or winding-up of the Company within the meaning of this Clause (v).
        
     (vi) Reacquired Shares. All shares of this Series which are at any time
redeemed pursuant to Clause (iii) or redeemed and exchanged pursuant to Clause
(iv) above and all shares of this Series which are otherwise reacquired by the
Company and subsequently cancelled by the Board of Directors of the Company
shall have the status of authorized but unissued Preferred Stock, without
designation as to series, subject to reissuance by the Board of Directors of the
Company as shares of this Series or shares of any one or more other series.

                                      - 6 -

<PAGE>   20

     (vii) Voting Rights. Except as otherwise provided in this Clause (vii) or
as otherwise provided by law or the Restated Certificate of Incorporation of the
Company, holders of shares of this Series have no voting rights.

     If at any time dividends payable on the shares of this Series are in
arrears and unpaid in an aggregate amount equal to or exceeding the aggregate
amount of dividends payable thereon for six quarterly dividend periods, the
holders of the shares of this Series, together with the holders of any other
series of Preference Shares as to which dividends are in arrears and unpaid in
an aggregate amount equal to or exceeding the aggregate amount of dividends
payable for six quarterly dividend periods (but only if the holders of the
shares of such other series would otherwise have a right to elect Directors as a
result of a dividend arrearage), will have the exclusive right (superseding the
separate right of such other series to elect Directors so long as shares of this
Series remain outstanding, except as otherwise expressly provided in the
certificate of designation establishing such other series), voting separately as
a class with any such other series, to elect two Directors of the Company, such
Directors to be in addition to the number of Directors constituting the Board of
Directors of the Company immediately prior to the accrual of such right. Such
right of the holders of shares of this Series to elect two Directors shall, when
vested, continue until all dividends in default on the shares of this Series
shall have been paid in full and, when so paid, such right of the holders of
shares of this Series to elect two Directors separately as a class shall cease,
subject, always, to the same provisions for the vesting of such right of the
holders of the shares of this Series to elect two Directors in the case of
future dividend defaults. At any time when such right to elect such Directors
separately as a class shall have so vested, the Company may, and upon the
written request of the holders of record of not less than 20% of the total
number of shares of this Series and such other series of Preference Shares then
outstanding shall, call a special meeting of the holders of such shares to fill
such newly-created directorships for the election of Directors. In the case of
such a written request, such special meeting shall be held within 90 days after
the delivery of such request and, in either case, at the place and upon the
notice provided by law and in the Bylaws of the Company, provided that the
Company shall not be required to call such a special meeting if such request is
received less than 120 days before the date fixed for the next ensuing annual
meeting of stockholders of the Company, in which case such newly-created
 directorships shall be filled by the holders of such shares of this Series
and such other series of Preference Shares at such meeting.

     The term of office of each Director elected pursuant to the preceding
paragraph shall terminate on the earlier of (x) the next annual meeting of
stockholders at which a successor shall have been elected and qualified or (y)
the termination of the right of the

                                      - 7 -

<PAGE>   21

holders of shares of this Series and such other series of Preference Shares to
vote for Directors pursuant to the preceding paragraph. If, prior to the end of
the term of any Director elected as aforesaid, a vacancy in the office of such
Director shall occur, such vacancy shall be filled for the unexpired term by the
appointment by the remaining Director elected as aforesaid of a new Director for
the unexpired term of such former Director. If both Directors so elected by the
holders of shares of this Series and such other series of Preference Shares
shall cease to serve as Directors before their terms shall expire, the holders
of the shares of this Series, together with the holders of such other series of
Preference Shares may, at a special meeting of the holders called as provided
above, elect successors to hold office for the unexpired terms of such Directors
whose places shall be vacant.

     The voting rights provided in this Clause (vii) shall be in addition to any
other right to vote provided to the holders of shares of this Series by law or
the Restated Certificate of Incorporation of the Company.

     (viii) No Preemptive Rights. The holders of shares of this Series shall
have no preemptive rights, including preemptive rights with respect to any
shares of capital stock or other securities of the Company convertible into or
carrying rights or options to purchase any such shares.

     (ix) Certain Definitions. As used in this Certificate, the following terms
shall have the following respective meanings:

     "Common Shares" shall mean any stock of any class of the Company which has
no preference in respect of dividends or of amounts payable in the event of any
voluntary or involuntary liquidation, dissolution or winding-up of the Company
and which is not subject to redemption by the Company.

     "Junior Shares" shall mean Preference Shares of any series or class of the
Company which are by their terms expressly made junior to shares of this Series
at the time outstanding as to dividends or as to the distribution of assets on
any voluntary or involuntary liquidation, dissolution or winding-up of the
Company or as to both dividends and distributions.

     "Parity Shares" shall mean Preference Shares which are by their terms on a
parity with the shares of this Series at the time outstanding both as to
dividends and as to the distribution of assets on any voluntary or involuntary
liquidation, dissolution or winding-up of the Company.

     "Preference Shares" shall mean any class or series of shares of the Company
ranking prior to at lease one other class or series of shares of the Company as
to the payment of dividends or the




                                      - 8 -

distribution of assets on any voluntary or involuntary liquidation, dissolution
or winding-up of the Company.

     IN WITNESS WHEREOF, the Company has caused this Certificate to be duly
executed on its behalf by its undersigned Chairman of the Board of Directors and
attested to by its Assistant Secretary this 18th day of December, 1990.

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

     The undersigned, the Chairman of the Board of Directors of Masco
Industries, Inc., a Delaware corporation (the "Company"), DOES HEREBY CERTIFY
that the following resolutions have been duly adopted by the Board of Directors
of the Company:

     RESOLVED, that pursuant to the authority expressly granted to and vested in
the Board of Directors of the Company by the provisions of the Restated
Certificate of Incorporation of the Company, this Board of Directors hereby
authorizes the issuance of a series (this "Series") of the Preferred Stock of
the Company (the "Preferred Stock") which shall consist of 1,000,000 shares, and
this Board of Directors hereby fixes the powers, designations, preferences and
relative, participating, optional or other special rights, and the
qualifications, limitations or restrictions thereof, of the shares of this
Series (in addition to the powers, designations, preferences and relative,
participating, optional or other special rights, and the qualifications,
limitations or restrictions thereof, set forth in the Restated Certificate of
Incorporation of the Company which are applicable to the Preferred Stock) as
follows:

     (i)  Designation. The designation of this Series shall be 10% Exchangeable
Preferred Stock. The number of shares of this Series shall be 1,000,000. The
liquidation value of shares of this Series shall be $100 per share.

     (ii) Dividends. (a) The dividend rate on shares of this Series shall be
$10.00 per share per annum. Dividends on shares of this Series shall be fully
cumulative and shall accrue, without interest, from the date of issuance of such
shares, and shall be payable, when and as declared by the Board of Directors out
of funds legally available therefor, in arrears on July 1, 1993 and quarterly in
arrears thereafter on October 1, January 1, April 1

                                      - 1 -

and July 1 of each year. The amount of dividends payable for the initial
dividend period or any period shorter than a full dividend period shall be
calculated on the basis of a 360-day year of twelve 30-day months. Holders of
shares of this Series shall be entitled to receive such dividends in preference
to and in priority over dividends upon the Common Shares (hereinafter defined)
and all Junior Shares (hereinafter defined), but subject to the rights of
holders of Preference Shares (hereinafter defined) having a preference and a
priority over the payment of dividends on the shares of this Series. Shares of
this Series shall be on a parity as to dividends with all Parity Shares
(hereinafter defined). The holders of shares of this Series shall not be
entitled to any dividends other than the dividends provided in this Clause (ii).

     (b)  If at any time the Company has failed to pay accrued dividends on any
shares of this Series or any Parity Shares at the time outstanding at the times
such dividends are payable, the Company shall not

          (1)  declare or pay any dividend on the Common Shares or on any Junior
Shares or make any payment on account of, or set apart money for a sinking or
other analogous fund for, the purchase, redemption or other retirement of, any
Common Shares or any Junior Shares or make any distribution in respect thereof,
either directly or indirectly and whether in cash or property or in obligations
or shares of the Company (other than in Common Shares or Junior Shares),

          (2)  purchase any shares of this Series or Parity Shares (except for a
consideration payable in Common Shares or Junior Shares) or redeem (or redeem
and exchange for subordinated Debentures as hereinafter provided) fewer than all
of the shares of this Series and all of the Parity Shares then outstanding, or

          (3)  permit any corporation or other entity directly or indirectly
controlled by the Company to purchase any Common Shares, Junior Shares, shares
of this Series or Parity Shares, 

unless, in the case of any such dividend, payment, setting apart, distribution,
purchase, redemption or other retirement, all dividends accrued and payable but
unpaid on shares of this Series and all Parity Shares have been or
contemporaneously are declared and paid in full or declared and a sum sufficient
for the payment thereof set aside for such payment. Unless and until all
dividends accrued and payable but unpaid on shares of this Series and all Parity
Shares at the time outstanding have been paid in full, all dividends declared by
the Company upon shares of this Series or Parity Shares shall be declared pro
rata with respect to all shares of this Series and all Parity Shares then
outstanding, so that the amounts of any dividends declared on shares of this
Series and such Parity Shares shall in all cases bear to each other the same
ratio that, at the time of such declaration, all accrued and payable but

                                      - 2 -

<PAGE>   25

unpaid dividends on shares of this Series and such Parity Shares, respectively,
bear to each other.

     (iii) Optional Redemptions for Cash. Subject to the restrictions in Clause
(ii) above, shares of this Series shall be redeemable at the option of the
Company in whole or from time to time in part in cash at $100 per share, plus an
amount equal to the dividends accrued and unpaid thereon to the redemption date.

     Not less than 30 nor more than 60 days prior to the date fixed for any
redemption of shares of this Series pursuant to this Clause (iii), a notice
shall be given by first class mail, postage prepaid, to the holders of record of
the shares of this Series to be redeemed at their respective addresses as the
same shall appear on the books of the Company, specifying the certificate
numbers of such shares, the effective date of the redemption and the place where
certificates for shares of this Series are to be surrendered for redemption and
stating that dividends on such shares of this Series will cease to accrue on and
after the redemption date, but neither failure to mail such notice, nor any
defect therein or in the mailing thereof, to any particular holder shall affect
the sufficiency of the notice or the validity of the proceedings for redemption
with respect to the other holders. Any notice which was mailed in the manner
herein provided shall be conclusively presumed to have been duly given whether
or not the holder receives the notice.

     If notice of redemption has been given pursuant to this Clause (iii) and
if, on or before the date fixed for redemption, the funds necessary for such
redemption shall have been set aside by the Company, separate and apart from its
other funds, in trust for the pro rata benefit of the holders of the shares so
called for redemption, then on and after the redemption date, notwithstanding
that any certificates for such shares have not been surrendered for
cancellation, dividends shall cease to accrue on the shares of this Series to be
redeemed and the holders of such shares shall cease to be stockholders with
respect to such shares and shall have no interest in or claims against the
Company by virtue thereof and shall have no voting or other rights with respect
to such shares, except the right to receive the moneys payable upon such
redemption, without interest thereon, upon surrender (and endorsement, if
required by the Company) of their certificates, and the shares evidenced thereby
shall no longer be outstanding. Subject to applicable escheat laws, any moneys
so set aside by the Company and unclaimed at the end of one year from the
redemption date shall revert to the general funds of the Company after which
reversion the holders of such shares so called for redemption shall look only to
the general funds of the Company for the payment of the redemption price. Any
interest accrued on funds so deposited shall be paid to the Company from time to
time. Any holder of record of the shares of this Series to be redeemed pursuant
to this Clause (iii) may waive its right to notice hereunder.

                                      - 3 -

<PAGE>   26

     In every case of redemption of less than all of the outstanding shares of
this Series pursuant to this Clause (iii), the shares to be redeemed shall be
selected (a) by lot or by such other manner as may be prescribed by resolution
of the Board of Directors of the Company and (b) to the extent Masco
Corporation, a Delaware corporation ("Masco"), or any subsidiary thereof, holds
shares of this Series, the Company shall allow Masco to select, in its sole
discretion, the specific shares of this Series then owned by Masco to be
redeemed, provided that Masco informs the Company no later than the day prior to
the date of such redemption of the specific shares Masco has selected for
redemption.

     (iv) Optional Redemption through Debenture Exchange.

     (a)  Subject to the restrictions in clause (ii) above and subclauses (b) 
and (d) of this Clause (iv), shares of this Series shall be redeemable at the
option of the Company, in whole or from time to time in part through the
issuance, in redemption of and in exchange for shares of this Series, of the
Company's Subordinated Debentures due the earlier of ten years from the date of
issuance or March 31, 2008 (hereinafter referred to as the "Subordinated
Debentures"), in the manner provided in this Clause (iv). The Subordinated
Debentures shall be issued in substantially the form on file with the Secretary
of the Company and identified to this Series, subject to any changes that may
be made to such Subordinated Debentures in order to qualify an indenture with
respect to such Subordinated Debentures. The Subordinated Debentures shall be
issued in series with the interest rate on each series being a rate per annum
that is 400 basis points over the Treasury Rate (as hereinafter defined) for
the week preceding the week in which the notice of redemption and exchange is
given to holders of shares of this Series as provided in subclause (c) of this
clause (iv) below. "Treasury Rate" means, the rate for direct obligations of
the United States ("Treasury Notes") having a remaining maturity of 10 years,
as published in the Federal Reserve Statistical Release H.15 (519) (or any
successor publication provided by the Board of Governors of the Federal Reserve
System) under the heading "Treasury Constant Maturities." In the event that a
rate for Treasury Notes having a remaining maturity of 10 years is not
published or reported for the prior week as provided above by 1:00 P.M., New
York City time, on the third business day preceding the day such notice of
redemption and exchange is given to such holders, then the Treasury Rate shall
be calculated by the Company and shall be a yield to maturity (expressed as a
bond equivalent, on the basis of a year of 365 or 366 days, as applicable, and
applied on a daily basis) of the arithmetic mean of the secondary market bid
rates, as of approximately 1:30 P.M., New York City time, on the date of such

     (b)  The Subordinated Debentures will be issued solely in redemption of and
in exchange for shares of this Series at the rate of $100 principal amount of
Subordinated Debentures for each share of this Series redeemed and exchanged on
the applicable Exchange Date (as defined below). An amount equal to all accrued
but unpaid dividends on such shares to the dividend payment date which coincides
with the date of redemption and exchange shall be paid in cash on the date of
such redemption and exchange. No redemption and exchange shall be for and
aggregate principal amount of Subordinated Debentures less than $5 million, and
no Subordinated Debentures in amounts other than $1,000 (and integral multiples
thereof) shall be issued in any redemption and exchange. Cash will be paid in
lieu of any such fraction of a Subordinated Debenture which would otherwise have
been issued.

     (c)  Not less than 30 nor more than 60 days prior to the date fixed for the
issue of Subordinated Debentures in redemption of and in exchange for shares of
this Series pursuant to this Clause (iv), a notice shall be given by first class
mail, postage prepaid, to the holders of record of the shares of this Series to
be redeemed and exchanged at their respective addresses as the same shall appear
on the books of the Company, specifying the certificate numbers of such
shares, the effective date of the redemption and exchange (the "Exchange Date")
and the place where certificates for shares of this Series are to be surrendered
for Subordinated Debentures and stating that dividends on such shares of this
Series will cease to accrue on and after the Exchange Date, but neither failure
to mail such notice, nor any defect therein or in the mailing thereof, to any
particular holder shall affect the sufficiency of the notice or the validity of
the proceedings for redemption and exchange with respect to the other holders.
Any notice which was mailed in the manner herein provided shall be conclusively
presumed to have been duly given whether or not the holder receives the notice.
Any holder of record of the shares of this Series to be redeemed and exchanged
pursuant to this Clause (iv) may waive its right to notice hereunder.

     If notice of redemption and exchange has been give pursuant to this Clause
(iv), then on or after the Exchange Date (unless the Company shall default in
issuing Subordinated Debentures in redemption of and in exchange for shares of
this Series to be redeemed and exchanged on such Exchange Date or shall fail to
pay or set aside accrued and unpaid dividends on such shares of this Series and
notwithstanding that any certificates for such shares of this Series have not
been surrendered for exchange), dividends shall cease to accrue on such shares
of this Series and the holders of such shares shall cease to be stockholders
with respect to such shares (provided, that the persons entitled to receive
Subordinated Debentures in exchange for such shares shall be treated for all
purposes as the registered holders of such Subordinated Debentures) and shall
have no interest in or claims against the Company by virtue thereof (except the
right to receive Subordinated Debentures

                                      - 5 -

and accrued dividends through the Exchange Date) and shall have no voting or
other rights with respect to such shares and such shares of this Series shall no
longer be outstanding. Upon the surrender (and endorsement, if required by the
Company) in accordance with such notice of the certificates for such shares of
this Series, such certificates shall be redeemed and exchanged for Subordinated
Debentures in accordance with this Clause (iv).

     (d)  In every case of redemption of less than all of the outstanding shares
of this Series pursuant to this Clause (iv), the shares shall be selected (a) by
lot or by such other manner as may be prescribed by resolution of the Board of
Directors of the Company and (b) to the extent Masco, or any subsidiary thereof,
holds shares of this Series, the Company shall allow Masco to select, in its
sole discretion, the specific shares of this Series then owned by Masco to be
redeemed, provided that Masco informs the Company no later than the day prior to
the date of such redemption of the specific shares Masco has selected for
redemption.

     (v)  Liquidation.

     (a)  The liquidation price of shares of this Series, in case of the
voluntary or involuntary liquidation, dissolution or winding-up of the Company,
shall be $100 per share, plus the amount per share of any dividends accrued
thereon and remaining unpaid at the date of such liquidation, dissolution or
winding-up.

     (b) In the event of any voluntary or involuntary liquidation, dissolution
or winding-up of the Company, the holders of shares of this Series shall
be entitled to receive the liquidation price of such shares held by them in
preference to and in priority over any distributions upon the Common Shares and
all Junior Shares, but subject to the rights of holders of Preference Shares
having a preference to and priority over the payment of distributions on the
shares of this Series. Upon payment in full of the liquidation price to which
the holders of shares of this Series are entitled, the holders of shares of this
Series will not be entitled to any further participation in any distribution of
assets by the Company. If the assets of the Company are not sufficient to pay in
full the liquidation price payable to the holders of shares of this Series and
the liquidation price payable to the holders of all Parity Shares, the holders
of all such shares shall share ratably in such distribution of assets in
accordance with the amounts which would be payable on such distribution if the
amounts to which the holders of shares of this Series and the holders of Parity
Shares are entitled were paid in full.

     (c)  Neither a consolidation or merger of the Company with or into any
other corporation, nor a merger of any other corporation with or into the
Company, nor a sale or transfer of all or any part of the Company's assets for
cash, securities or other property

                                      - 6 -

<PAGE>   29

shall be considered a liquidation, dissolution or winding-up of the Company
within the meaning of this Clause (v).

     (vi) Reacquired Shares. All shares of this Series which are at any time
redeemed pursuant to Clause (iii) above or redeemed and exchanged pursuant to
Clause (iv) above and all shares of this Series which are otherwise reacquired
by the Company and subsequently cancelled by the Board of Directors of the
Company shall have the status of authorized but unissued Preferred Stock,
without designation as to series, subject to reissuance by the Board of
Directors of the Company as shares of this Series or shares of any one or more
other series.

     (viii) Voting Rights. Except as otherwise provided in this Clause (vii) or
as otherwise provided by law or the Restated Certificate of Incorporation of the
Company, holders of shares of this Series have not voting rights.

     If at any time dividends payable on the shares of this Series are in
arrears and unpaid in an aggregate amount equal to or exceeding the aggregate
amount of dividends payable thereon for six quarterly dividend periods, the
holders of the shares of this Series, together with the holders of any other
series of Preference Shares then having a right to elect Directors as a result
of a dividend arrearage, will have the exclusive right (superseding the separate
right of such other series to elect Directors so long as shares of this Series
remain outstanding, except as otherwise expressly provided in the certificate of
designation establishing such other series), voting separately as a class with
any such other series, to elect two Directors of the Company, such Directors to
be in addition to the number of Directors constituting the Board of Directors of
the Company immediately prior to the accrual of such right. Such right of the
holders of shares of this Series to elect two Directors shall, when vested,
continue until all dividends in default on the shares of this Series shall have
been paid in full and, when so paid, such right of the holders of shares of this
Series to elect two Directors separately as a class shall cease, subject,
always, to the same provisions for the vesting of such right of the holders of
the shares of this Series to elect two Directors in the case of future dividend
defaults. At any time when such right to elect such Directors separately as a
class shall have so vested, the Company may, and upon the written request of the
holders of record of not less than 20% of the total number of shares of this
Series and such other series of Preference Shares then outstanding shall, call a
special meeting of the holders of such shares to fill such newly-created
directorships for the election of Directors. In the case of such a written
request, such special meeting shall be held within 90 days after the delivery of
such request and, in either case, at the place and upon the notice provided by
law and in the Bylaws of the Company, provided that the Company shall not be
required to call such a special meeting if such request is received less than
120 days before the date fixed

                                      - 7 -

<PAGE>   30

for the next ensuing annual meeting of stockholders of the Company, in which
case such newly-created directorships shall be filled by the holders of such
shares of this Series and such other series of Preference Shares at such
meeting.

     The term of office of each Director elected pursuant to the preceding
paragraph shall terminate on the earlier of (x) the next annual meeting of
stockholders at which a successor shall have been elected and qualified or (y)
the termination of the right of the holders of shares of this Series and such
other series of Preference Shares to vote for Directors pursuant to the
preceding paragraph. If, prior to the end of the term of any Director elected as
aforesaid, a vacancy in the office of such Director shall occur, such vacancy
shall be filled for the unexpired term by the appointment by the remaining
Director elected as aforesaid of a new Director for the unexpired term of such
former Director. If both Directors so elected by the holders of shares of this
Series and such other series of Preference Shares shall cease to serve as
Directors before their terms shall expire, the holders of the shares of this
Series, together with the holders of such other series of Preference Shares may,
at a special meeting of the holders called as provided above, elect successors
to hold office for the unexpired terms of such Directors whose places shall be
vacant.

     The voting rights provided in this Clause (vii) shall be in addition to any
other right to vote provided to the holders of Shares of this Series by law or
the Restated Certificate of Incorporation of the Company.

     (viii) No Preemptive Rights. The holders of shares of this Series shall
have no preemptive rights, including preemptive rights with respect to any
shares of capital stock or other securities of the Company convertible into or
carrying rights or options to purchase any such shares.

     (ix) Certain Definitions. As used in this Certificate, the following terms
shall have the following respective meanings:

     "Common Shares" shall mean any stock of any class of the Company which has
no preference in respect of dividends or of amounts payable in the event of any
voluntary or involuntary liquidation, dissolution or winding-up of the Company
and which is not subject to redemption by the Company.

     "Junior Shares" shall mean Preference Shares of any series or class of the
Company which are by their terms expressly made junior to shares of this Series
at the time outstanding as to dividends or as to the distribution of assets on
any voluntary or involuntary liquidation, dissolution or winding-up of the
Company or as to both dividends and distributions.

                                      - 8 -

<PAGE>   31

     "Parity Shares" shall mean Preference Shares which are by their terms on a
parity with the shares of this Series at the time outstanding both as to
dividends and as to the distribution of assets on any voluntary or involuntary
liquidation, dissolution or winding-up of the Company.

     "Preference Shares" shall mean any class or series of shares of the Company
ranking prior to at least one other class or series of shares of the Company as
to the payment of dividends or the distribution of assets on any voluntary or
involuntary liquidation, dissolution or winding-up of the Company.

executed on its behalf by its undersigned Chairman of the Board of Directors and
attested to by its Assistant Secretary this 23rd day of March, 1993.

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

     The undersigned, the Chairman of the Board of Directors of MascoTech, Inc.,
a Delaware corporation (the "Company"), DOES HEREBY CERTIFY that the following
resolutions were duly adopted by the Pricing Committee of the Board of Directors
of the Company (pursuant to the authority conferred upon it by the Board of
Directors) and by the Board of Directors (pursuant to the authority granted and
vested in it by the provisions of the Restated Certificate of Incorporation of
the Company), respectively.

     A.   On June 30, 1993, the Pricing Committee of the Board of Directors
adopted the following resolution: 

     RESOLVED, that pursuant to the authority conferred upon the Pricing
Committee of the Board of Directors of the Company, this Pricing Committee
hereby authorizes the issuance of a series (this "Series"), of the Preferred
Stock of the Company ( the "Preferred Stock") which shall consist of 11,500,000 
shares, and this Pricing Committee hereby fixes the powers, designations,
preferences and relative, participating, optional or other special rights, and
the qualifications, limitations or restrictions thereof, of the shares of this
Series (in addition to the powers, designations, preferences and relative,
participating, optional or other special rights, and the qualifications,
limitations, or restrictions thereof, set forth in the Restated Certificate of
Incorporation of the Company which are applicable to the Preferred Stock and in
addition to the voting rights established by the resolutions of the Board of
Directors of the Company adopted June 26, 1993) as follows:

     (1)  Designation. The designation of this Series shall be $1.20 Convertible
Preferred Stock. The number of shares of this Series shall be 11,500,000. The
liquidation value of shares of this Series shall be $20.00 per share.

     (2)  Dividends. (a) The holders of shares of this Series shall be entitled
to receive, when, as and if declared by the Board of Directors of the Company
out of funds legally available therefor, cumulative preferential dividends from
the issue date of such shares, at the rate per share of $1.20 per annum, and no
more, payable quarterly for each share of this Series, payable in arrears on the
first day of each January, April, July and October, respectively (each such date
being hereinafter referred to as a "Dividend Payment Date") or, if any Dividend
Payment

                                      - 1 -

<PAGE>   35

Date is not a business day, then the Dividend Payment Date shall be the next
succeeding business day; provided, however, that with respect to any dividend
period during which a redemption occurs, the Company may, at its option, declare
accrued dividends to, and pay such dividends on, the redemption date, in which
case such dividends would be payable on the redemption date in cash to the
holders of the shares of this Series as of the record date for such dividend
payment and such accrued dividends would not be included in the calculation of
the related Call Price (as hereinafter defined). Each dividend on the shares of
this Series shall be payable to holders of record as they appear on the stock
books of the Company on such record dates, not less than 10 nor more than 60
days preceding the payment dates thereof, as shall be fixed by the Board of
Directors. The first dividend payment shall be for the period from the issue
date of the shares of this Series to and including September 30, 1993 and shall
be payable on October 1, 1993. Dividends (or amounts equal to accrued and unpaid
dividends) payable on shares of this Series for any period shorter than a
quarterly dividend period shall be computed on the basis of a 360-day year of
twelve 30-day months.

     Dividends on the shares of this Series shall accrue (whether or not the
Company has earnings, whether or not there are funds legally available for the
payment of such dividends and whether or not such dividends are declared) on a
daily basis from the previous Dividend Payment Date, except that the first
dividend shall accrue from the date of issuance of the shares of this Series.
Dividends accumulate to the extent they are not paid on the Dividend Payment
Date for the quarter for which they accrue. Accumulated unpaid dividends shall
not bear interest. 

     (b) Unless full cumulative dividends, if any, accrued on the shares of this
Series which are payable in cash have been paid or contemporaneously are
declared and paid and a sum set aside sufficient for such payment through the
most recent Dividend Payment Date, then, whether or not the Mandatory Conversion
Date (as hereinafter defined) has occurred:

     (i)       No full cash dividend shall be declared by the Board of Directors
               or paid or set aside for payment by the Company or other
               distribution declared or made on any shares of the Company
               ranking on a parity with the shares of this Series as to
               dividends;

     (ii)      No dividend (other than a dividend or distribution paid in shares
               of, or warrants, rights or options exercisable for or convertible
               into shares of, Common Stock or in any other shares of the
               Company ranking junior to the shares of this Series as to
               dividends and upon liquidation) shall be declared or paid or set
               aside for payment or other distribution declared or made upon the
               Common Stock or upon any other shares of the Company ranking
               junior to the shares of this Series as to dividends; and

     (iii)     No Common Stock or any other shares of the Company ranking junior
               to or on a parity with the shares of this Series as to dividends
               or upon liquidation

                                      - 2 -

<PAGE>   36

               shall be redeemed, purchased or otherwise acquired for any
               consideration (or any moneys be paid to or made available for a
               sinking fund for the redemption of any shares of any such series
               or class) by the Company, except by conversion into or exchange
               for shares of the Company ranking junior to the shares of this
               Series as to dividends and upon liquidation.

When dividends which are payable in cash have not been paid or set aside in full
with respect to the shares of this Series and any other shares of the Company
ranking on a parity with the shares of this Series as to dividends, all
dividends declared with respect to the shares of this Series and any other
shares of the Company ranking on a parity with the shares of this Series as to
dividends shall be declared pro rata so that the amount of dividends declared
per share on this Series and such other shares shall in all cases bear to each
other the same ratio that, at the time of declaration, accrued and payable but
unpaid dividends per share on the shares of this Series and such other shares
bear to each other. Holders of the shares of this Series shall not be entitled
to any dividends, whether payable in cash, property or stock, in excess of full
cumulative dividends, as herein described.

      (c)      Subject to the foregoing provisions of this paragraph (2) and
paragraph (3)(d), the Board of Directors may declare and the Company may pay or
set aside for payment dividends and other distributions on any shares of the
Company ranking on a parity with or junior to the shares of this Series as to
dividends or upon liquidation, and may redeem, purchase or otherwise acquire any
shares of the Company ranking on a parity with or junior to the shares of this
Series as to dividends or upon liquidation, and the holders of the shares of
this Series shall not be entitled to share therein.

     (d)       Any dividend payment made on the shares of this Series shall
first be credited against the earliest accrued but unpaid dividend due with
respect to the shares of this Series.

     (e)       All dividends paid with respect to the shares of this Series
shall be paid pro rata to the holders entitled thereto.

     (f)       Holders of the shares of this Series shall be entitled to receive
dividends in preference to and in priority over any dividends upon any shares of
the Company ranking junior to the shares of this Series as to dividends, but
subject to the rights of holders of shares of the Company having a preference
and a priority over the payment of dividends on the shares of this Series.

     (3)  Redemptions and Conversions.

     (a)  Mandatory Conversion. On July 1, 1997 (the "Mandatory Conversion
Date"), each outstanding share of this Series shall convert automatically (the
"Mandatory Conversion") into shares of Common Stock at the Common Equivalent
Rate (as hereinafter defined) in effect on the Mandatory Conversion Date and the
right to receive an amount in cash equal to all accrued and unpaid dividends on
such share of this Series (other than dividends payable to a holder of

                                      - 3 -

<PAGE>   37

record on a prior date) to the Mandatory Conversion Date, whether or not
declared, out of funds legally available for the payment of dividends, subject
to the right of the Company to redeem the shares of this Series on or after the
Initial Redemption Date (as hereinafter defined) and prior to the Mandatory
Conversion Date, as described below, and subject to the conversion of the shares
of this Series at the option of the holder at any time prior to the Mandatory
Conversion Date. The Common Equivalent Rate is initially one share of Common
Stock for each share of this Series and is subject to adjustment as set forth
below. Dividends on the shares of this Series shall cease to accrue and such
shares shall cease to be outstanding on the Mandatory Conversion Date. The
Company shall make such arrangements as it deems appropriate for the issuance of
certificates representing shares of Common Stock and for the payment of cash in
respect of such accrued and unpaid dividends, if any, or cash in lieu of
fractional shares, if any, in exchange for and contingent upon surrender of
certificates representing the shares of this Series, and the Company may defer
the payment of dividends on such shares of Common Stock and the voting thereof
until, and make such payment and voting contingent upon, the surrender of such
certificates representing the shares of this Series, provided that the Company
shall give the holders of the shares of this Series such notice of any such
actions as the Company deems appropriate and upon such surrender such holders
shall be entitled to receive such dividends declared and paid on such shares of
Common Stock subsequent to the Mandatory Conversion Date. Amounts payable in
cash in respect of the shares of this series or in respect of such shares of
Common Stock shall not bear interest.

     (b)  Redemption by the Company.

     (i)  Right to Redeem. Shares of this Series are not redeemable by the
Company prior to July 1, 1996 (the "Initial Redemption Date"). At any time and
from time to time on or after the Initial Redemption Date and prior to the
Mandatory Conversion Date, the Company shall have the right to redeem, in whole
or in part, the outstanding shares of this Series. Upon any such redemption, the
Company shall deliver to the holders of shares of this Series, in accordance
with the provisions of this Certificate, in exchange for each share so redeemed,
a number of shares of Common Stock equal to (A) the Call Price (as hereinafter
defined) in effect on the redemption date, divided by (B) the Current Market
Price (as hereinafter defined) of the Common Stock determined as of the date
which is one trading day prior to the public announcement of the redemption. The
Call Price of each share of this Series is the sum of (X) $20.30 on and after
the Initial Redemption Date through September 30, 1996, $20.225 on and after
October 1, 1996 through December 31, 1996, $20.15 on and after January 1, 1997
through March 31, 1997, $20.075 on and after April 1, 1997 through May 31, 1997
and $20.00 on and after June 1, 1997 until the Mandatory Conversion Date and (Y)
all accrued and unpaid dividends thereon to the redemption date (other than
dividends payable to a holder of record as of a prior date), subject to the
right of the Company pursuant to paragraph (2) to pay such accrued and unpaid
dividends in cash. The public announcement of any call for redemption shall be
made prior to the mailing of the notice of such call to holders of shares of
this Series as described below. If fewer than all the outstanding shares of this
Series are to be redeemed, shares to be redeemed shall be selected by the
Company from outstanding shares of this Series not previously redeemed by lot or
pro rata (as nearly as may be practicable) or by any other

                                      - 4 -

<PAGE>   38

method determined by the Board of Directors of the Company in its sole
discretion to be equitable.

     (ii) Current Market Price. As used in this subparagraph (b), the term
"Current Market Price" per share of the Common Stock on any date of
determination means the lesser of (X) the average of the Closing Prices (as
hereinafter defined) of the Common Stock for the fifteen consecutive Trading
Dates (as hereinafter defined) ending on and including such date of
determination, and (Y) the Closing Price of the Common Stock for such date of
determination; provided, however, that, with respect to any redemption of shares
of this Series, if any event that results in an adjustment of the Common
Equivalent Rate occurs during the period beginning on the first day of such
fifteen-day period and ending on the applicable redemption date, the Current
Market Price as determined pursuant to the foregoing shall be appropriately
adjusted to reflect the occurrence of such event.

     (iii) Notice of Redemption. The Company shall provide notice of any
redemption of the shares of this Series to holders of record of this Series to
be called for redemption not less than 15 nor more than 60 days prior to the
date fixed for such redemption. Such notice shall be provided by mailing notice
of such redemption first class postage prepaid, to each holder of record of
shares of this Series to be redeemed, at such holder's address as it appears on
the stock register of the Company; provided, however, that neither failure to
give such notice nor any defect therein shall affect the validity of the
proceeding for the redemption of any shares of this Series to be redeemed.

     Each such notice shall state, as appropriate, the following and may contain
such other information as the Company deems advisable:

     (A)      the redemption date;
     (B)      that all outstanding shares of this Series are to be redeemed or,
              in the case of a call for redemption of fewer than all
              outstanding shares of this Series, the number of such shares held
              by such holder to be redeemed;

     (C)      the Call Price, the number of shares of Common Stock deliverable
              upon redemption of each share of this Series to be redeemed and
              the Current Market Price used to calculate such number of shares
              of Common Stock;

     (D)      the place or places where certificates for such shares are to be
              surrendered for redemption; and

     (E)      that dividends on the shares of this Series to be redeemed shall
              cease to accrue on such redemption date (except as otherwise
              provided herein).

      (iv)    Deposit of Shares and Funds. The Company's obligation to deliver
              shares of Common Stock and provide funds upon redemption in
              accordance with this paragraph (3) shall

                                      - 5 -

<PAGE>   39

be deemed fulfilled if, on or before a redemption date, the Company shall
irrevocably deposit, with a bank or trust company, or an affiliate of a bank or
trust company, having an office or agency in New York City and having a capital
and surplus of at least $50,000,000, or shall set aside or make other reasonable
provision for the issuance of such number of shares of Common Stock as are
required to be delivered by the Company pursuant to this paragraph (3) upon the
occurrence of the related redemption (and for the payment of cash in lieu of the
issuance of fractional share amounts and accrued and unpaid dividends payable in
cash on the shares to be redeemed as and to the extent provided by this
paragraph (3)). Any interest accrued on such funds shall be paid to the Company
from time to time. Any shares of Common Stock or funds so deposited and
unclaimed at the end of two years from such redemption date shall be repaid and
released to the Company, after which the holder or holders of such shares of
this Series so called for redemption shall look only to the Company for delivery
of such shares of Common Stock or funds.

     (v)  Surrender of Certificates; Status. Each holder of shares of this
Series to be redeemed shall surrender the certificates evidencing such shares
(properly endorsed or assigned for transfer, if the Board of Directors of the
Company shall so require and the notice shall so state) to the Company at the
place designated in the notice of such redemption and shall thereupon be
entitled to receive certificates evidencing shares of Common Stock and to
receive any funds payable pursuant to this paragraph (3) following such
surrender and following the date of such redemption. In case fewer than all the
shares represented by any such surrendered certificate are called for
redemption, a new certificate shall be issued at the expense of the Company
representing the unredeemed shares. If such notice of redemption shall have been
given, and if on the date fixed for redemption shares of Common Stock and funds
necessary for the redemption shall have been irrevocably either set aside by the
Company separate and apart from its other funds or assets in trust for the
account of the holders of the shares to be redeemed or converted (and so as to
be and continue to be available therefor) or deposited with a bank or a trust
company or an affiliate thereof as provided herein or the Company shall have
made other reasonable provision therefor, then, notwithstanding that the
certificates evidencing any shares of this Series so called for redemption or
subject to conversion shall not have been surrendered, the shares represented.
thereby so called for redemption shall be deemed no longer outstanding,
dividends with respect to the shares so called for redemption shall cease to
accrue on the date fixed for redemption (except that holders of shares of this
Series at the close of business on a record date for any payment of dividends
shall be entitled to receive the dividend payable on such shares on the
corresponding Dividend Payment Date notwithstanding the redemption of such
shares following such record date and prior to such Dividend Payment Date) and
all rights with respect to the shares so called for redemption shall forthwith
after such date cease and terminate, except for the rights of the holders to
receive the shares of Common Stock and funds, if any, payable pursuant to this
paragraph (3) without interest upon surrender of their certificates therefor.
Holders of shares of this Series that are redeemed shall not be entitled to
receive dividends declared and paid on such shares of Common Stock, and such
shares of Common Stock shall not be entitled to vote, until such shares of
Common Stock are issued upon the surrender of the certificates representing such
shares of this Series and upon such surrender

                                      - 6 -

<PAGE>   40

such holders shall be entitled to receive such dividends declared and paid on
such shares of Common Stock subsequent to such redemption date.

     (c)  Conversion at Option of Holder. Shares of this Series are convertible,
in whole or in part, at the option of the holders thereof, at any time prior to
the Mandatory Conversion Date, unless previously redeemed, into shares of Common
Stock at a rate of .806 of a share of Common Stock for each share of this Series
(the "Optional Conversion Rate") (equivalent to a conversion price of $24.81 per
share of Common Stock), subject to adjustment as set forth below. The right to
convert shares of this Series called for redemption shall terminate at the close
of business on the redemption date.

     Conversion of shares of this Series may be effected by delivering
certificates evidencing such shares, together with written notice of conversion
and a proper assignment of such certificates to the Company or in blank, to the
office or agency to be maintained by the Company for that purpose (and, if
applicable, payment of an amount equal to the dividend payable on such shares),
and otherwise in accordance with conversion procedures established by the
Company. Each conversion shall be deemed to have been effected immediately prior
to the close of business on the date on which the foregoing requirements shall
have been satisfied. The conversion shall be at the Optional Conversion Rate in
effect at such time and on such date.

     Holders of shares of this Series at the close of business on a record date
for any payment of dividends shall be entitled to receive the dividend payable
on such shares on the corresponding Dividend Payment Date notwithstanding the
conversion of such shares following such record date and prior to such Dividend
Payment Date. However, shares of this Series surrendered for conversion after
the close of business on a record date for any payment of dividends and before
the opening of business on the next succeeding Dividend Payment Date must be
accompanied by payment in cash of an amount equal to the dividend thereon which
is to be paid on such Dividend Payment Date (unless such shares are subject to
redemption on a redemption date in that period). Except as provided above, the
Company shall make no payment or allowance for unpaid dividends whether or not
in arrears, on converted shares of this Series or for dividends or distributions
on the shares of Common Stock issued upon such conversion. 

     (d)  Common Equivalent Rate and Optional Conversion Rate Adjustments. The
Common Equivalent Rate and the Optional Conversion Rate shall be subject to
adjustment from time to time as provided below in this paragraph.

     (i)       If the Company shall:

               (A)       pay a dividend or make a distribution with respect to
                         its Common Stock in shares of such stock,

               (B)       subdivide or split its outstanding Common Stock into a
                         greater number of shares,

                                      - 7 -

<PAGE>   41

               (C)       combine its outstanding shares of Common Stock into a
                         smaller number of shares, or

               (D)       issue by reclassification of its shares of Common Stock
                         any shares of common stock of the Company,

               then, in any such event, the Common Equivalent Rate and the
               Optional Conversion Rate in effect immediately prior to such
               event shall each be adjusted so that the holder of any shares of
               this Series shall thereafter be entitled to receive, upon
               Mandatory Conversion or upon conversion at the option of the
               holder, the number of shares of Common Stock of the Company which
               such holder would have owned or been entitled to receive
               immediately following any event described above had such shares
               of this Series been converted immediately prior to such event or
               any record date with respect thereto. Such adjustment shall
               become effective at the opening of business on the business day
               next following the record date for determination of stockholders
               entitled to receive such dividend or distribution in the case of
               a dividend or distribution and shall become effective immediately
               after the effective date in the case of a subdivision, split,
               combination or reclassification. Such adjustment shall be made
               successively.

     (ii)      If the Company shall, after the date hereof, issue rights or
               warrants to all holders of its Common Stock entitling them (for a
               period not exceeding forty-five days from the date of such issu-
               ance) to subscribe for or purchase shares of Common Stock at a
               price per share less than the current market price of the Common
               Stock, then in each case the Common Equivalent Rate and Optional
               Conversion Rate shall each be adjusted by multiplying the Common
               Equivalent Rate and the Optional Conversion Rate, in effect
               immediately prior to the date of issuance of such rights or war-
               rants, by a fraction, of which the numerator shall be the number
               of shares of Common Stock outstanding on the date of issuance of
               such rights or warrants, immediately prior to such issuance, plus
               the number of additional shares of Common Stock offered for sub-
               scription or purchase pursuant to such rights or warrants, and of
               which the denominator shall be the number of shares of Common
               Stock outstanding on the date of issuance of such rights or war-
               rants, immediately prior to such issuance, plus the number of
               additional shares of Common Stock which the aggregate offering
               price of the total number of shares of Common Stock so offered ."
               for subscription or purchase pursuant to such rights or warrants
               would purchase at such current market price (determined by multi-
               plying such total number of shares by the exercise price of such
               rights or warrants and dividing the product so obtained by such
               current market price). Such adjustment shall become effective at
               the opening of business on the business day next following the
               record date for the determination of stockholders entitled to
               receive such rights or warrants. To the extent that shares of
               Common Stock are not delivered

                                      - 8 -

<PAGE>   42

               after the expiration of such rights or warrants, the Common
               Equivalent Rate shall be readjusted to the Common Equivalent Rate
               which would then be in effect had the adjustments been made upon
               the issuance of such rights or warrants been made upon the basis
               of delivery of only the number of shares of Common Stock actually
               delivered. Such adjustment shall be made successively.

     (iii)     If the Company shall pay a dividend or make a distribution to all
               holders of its Common Stock of evidences of its indebtedness or
               other assets (excluding any dividends or distributions referred
               to in subparagraph (i) above or any cash dividends) or shall
               issue to all holders of its Common Stock rights or warrants to
               subscribe for or purchase any of its securities (other than those
               referred to in subparagraph (ii) above), then in each such case,
               the Common Equivalent Rate and the Optional Conversion Rate shall
               each be adjusted by multiplying the Common Equivalent Rate and
               the Optional Conversation Rate in effect on the record date men-
               tioned below, by a fraction of which the numerator shall be the
               current market price per share of the Common Stock on the record
               date for the determination of stockholders entitled to receive
               such dividend or distribution, and of which the denominator shall
               be such current market price per share of Common Stock less the
               fair market value (as determined by the Board of Directors of the
               Company, whose determination shall be conclusive, and described
               in a resolution adopted with respect thereto) as of such record
               date of the portion of the assets or evidences of indebtedness so
               distributed or of such subscription rights or warrants applicable
               to one share of Common Stock. Such adjustment shall become
               effective on the opening of business on the business day next
               following the record date for the determination of stockholders
               entitled to receive such dividend or distribution. Such
               adjustment shall be made successively.

     (iv)      Any shares of Common Stock issuable in payment of a dividend
               shall be deemed to have been issued immediately prior to the
               close of business on the record date for such dividend for
               purposes of calculating the number of outstanding shares of
               Common Stock under subparagraph (ii) above. For purposes of any
               computation under subparagraphs (ii) and (iii) above, the current
               market price per share of Common Stock at any date shall be
               deemed to be the average of the daily Closing Prices for the
               thirty consecutive Trading Dates preceding the date in
               question; provided, however, if any event that results in an
               adjustment of the Common Equivalent Rate occurs during such
               thirty-day period, the current market price as determined
               pursuant to the foregoing shall be appropriately adjusted to
               reflect the occurrence of such event.

     (v)       The Company shall also be entitled to make upward adjustments in
               the Common Equivalent Rate, the Optional Conversion Rate and the
               Call Price,

                                      - 9 -

<PAGE>   43

               as it in its discretion shall determine to be advisable, in order
               that any stock dividends, subdivisions of shares, distribution of
               rights to purchase stock or securities, or distribution of
               securities convertible into or exchangeable for stock (or any
               transaction which could be treated as any of the foregoing
               transactions pursuant to Section 305 of the Internal Revenue Code
               of 1986, as amended) hereafter made by the Company to its
               stockholders shall not be taxable.

     (vi)      In any case in which subparagraph (3)(d) shall require that an
               adjustment as a result of any event become effective at the
               opening of business on the business day next following a record
               date and the date fixed for conversion pursuant to subparagraph
               (3)(a) or redemption pursuant to subparagraph (3)(b) occurs after
               such record date, but before the occurrence of such event, the
               Company may in its sole discretion, elect to defer the following
               until after the occurrence of such event: (A) issuing to the
               holder of any converted or redeemed shares of this Series the
               additional shares of Common Stock issuable upon such conversion
               or redemption over the shares of Common Stock issuable before
               giving effect to such adjustment and (B) paying to such holder
               any amount in cash in lieu of a fractional share of Common Stock
               pursuant to subparagraph (3)(g).

     (vii)     All adjustments to the Common Equivalent Rate and the Optional
               Conversion Rate shall be calculated to the nearest 1/1000th of a
               share of Common Stock (or if there is not a nearest 1/1000th of a
               share to the next lower 1/1000th of a share). No adjustment in
               the Common Equivalent Rate and the Optional Conversion Rate shall
               be required unless such adjustment would require an increase or
               decrease of at least one percent therein; provided, however, that
               any adjustments which by reason of this subparagraph are not
               required to be made shall be carried forward and taken into
               account in any subsequent adjustment.

     (e)  Adjustment for Consolidation or Merger. In case of any consolidation
or merger to which the Company is a party (other than a merger or consolidation
in which the Company is the continuing corporation and in which the Common Stock
outstanding immediately prior to the merger or consolidation remains unchanged),
or in case of any sale or transfer to another corporation of the property of the
Company as an entirety or substantially as an entirety, or in case of any
statutory exchange of securities with another corporation (other than in connec-
tion with a merger or acquisition), proper provision shall be made so that
each share of this Series shall, after consummation of such transaction,
be subject to (i) conversion at the option of the holder into the kind and
amount of securities, cash or other property receivable upon consummation of
such transaction by a holder of the number of shares of Common Stock into which
such share of this Series might have been converted immediately prior to
consummation of such transaction, (ii) conversion on the Mandatory Conversion
Date into the kind and amount of securities, cash or other property receivable
upon consummation of such transaction by a

                                     - 10 -

<PAGE>   44

holder of the number of shares of Common Stock into which such share of this
Series would have converted if the conversion on the Mandatory Conversion Date
had occurred immediately prior to the date of consummation of such transaction,
and (iii) redemption on any redemption date in exchange for the kind and amount
of securities, cash or other property receivable upon consummation of such
transaction by a holder of the number of shares of Common Stock that would have
been issuable at the Call Price in effect on such redemption date upon a
redemption of such share immediately prior to consummation of such transaction,
assuming that the public announcement of such redemption had been made on the
last possible date permitted by the terms of this Series and applicable law;
assuming in each case that such holder of Common Stock failed to exercise rights
of election, if any, as to the kind or amount of securities, cash or other
property receivable upon consummation of such transaction (provided that if the
kind or amount of securities, cash or other property receivable upon
consummation of such transaction is not the same for each non-electing share,
then the kind and amount of securities, cash or other property receivable upon
consummation of such transaction for each non-electing share shall be deemed to
be the kind and amount so receivable per share by a plurality of the
non-electing shares). The kind and amount of securities into which the shares of
this Series shall be convertible after consummation of such transaction shall be
subject to adjustment as described in the immediately preceding paragraph
following the date of consummation of such transaction. The Company may not
become a party to any such transaction unless the terms thereof are consistent
with the foregoing.

     (f)  Notice of Adjustments. Whenever the Common Equivalent Rate and 
Optional Conversion Rate are adjusted as herein provided, the Company shall:

     (i)       forthwith compute the adjusted Common Equivalent Rate and
               Optional Conversion Rate in accordance herewith and prepare a
               certificate signed by an officer of the Company setting forth the
               adjusted Common Equivalent Rate and the Optional Conversion Rate,
               the method of calculation thereof in reasonable detail and the
               facts requiring such adjustment and upon which such adjustment is
               based, which certificate shall be conclusive, final and binding
               evidence of the correctness of the adjustment, and file such
               certificate forthwith with the transfer agent for the shares of
               this Series and the Common Stock; and

     (ii)      mail a notice to the holders of the outstanding shares of this
               Series stating that the Common Equivalent Rate and the Optional
               Conversion Rate have been adjusted, the facts requiring such
               adjustment and upon which such adjustment is based and setting.
               forth the adjusted Common Equivalent Rate and Optional Conversion
               Rate, such notice to be mailed at or prior to the time the
               Company mails an interim statement to its stockholders covering
               the fiscal quarter during which the facts requiring such
               adjustment occurred, but in any event within 45 days of the end
               of such fiscal quarter.

     (g)  Notices. In case, at any time while any of the shares of this Series 
are outstanding,

                                     - 11 -

     (i)       the Company shall declare a dividend (or any other distribution)
               on its Common Stock, excluding any cash dividends; or

     (ii)      the Company shall authorize the issuance to all holders of its
               Common Stock of rights or warrants to subscribe for or purchase
               shares of its Common Stock or of any other subscription rights or
               warrants; or

     (iii)     of any reclassification of Common Stock of the Company (other
               than a subdivision or combination thereof) or of any
               consolidation or merger to which the Company is a party and for
               which approval of any stockholders of the Company is required
               (except for a merger of the Company into one of its subsidiaries
               solely for the purpose of changing the corporate domicile of the
               Company to another state of the United States and in connection
               with which there is no substantive change in the rights or privi-
               leges of any securities of the Company other than changes
               resulting from differences in the corporate statutes of the then
               existing and the new state of domicile), or of the sale or
               transfer of all or substantially all of the assets of the
               Company; or

     (iv)      of the voluntary or involuntary dissolution, liquidation or
               winding up of the Company;

then the Company shall cause to be filed at each office or agency maintained for
the purpose of conversion of the shares of this Series, and shall cause to be
mailed to the holders of shares of this Series at their last addresses as they
shall appear on the stock register, at least 10 days before the date hereinafter
specified (or the earlier of the dates hereinafter specified, in the event that
more than one date is specified), a notice stating (A) the date on which a
record is to be taken for the purpose of such dividend, distribution, rights or
warrants, or, if a record is not to be taken, the date as of which the holders
of Common Stock of record to be entitled to such dividend, distribution, rights
or warrants are to be determined, or (B) the date on which any such
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding up is expected to become effective, and the date as of
which it is expected that holders of Common Stock of record shall be entitled to
exchange their Common Stock for securities or other property (including cash),
if any, deliverable upon such reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation or winding up. The failure to give or receive
the notice required by this paragraph (g) or any defect therein shall not affect
the legality or validity of any such dividend, distribution, right or
warrant or other action.

     (h)  Effect of Conversions and Redemptions. The person or persons in whose
name or names any certificate or certificates for shares of Common Stock shall
be issuable upon any conversion or redemption shall be deemed to have become on
the date of any such conversion or redemption the holder or holders of record of
the shares represented thereby; provided, however, that any such surrender on
any date when the stock transfer books of the Company shall be closed shall
constitute the person or persons in whose name or names the certificate or
certificates for such shares are to be issued as the record holder or holders
thereof for all

                                     - 12 -

purposes at the opening of business on the next succeeding day on which such
stock transfer books are open.

     (i)  No Fractional Shares. No fractional shares or script representing
fractional shares of Common Stock shall be issued upon the redemption or
conversion of any shares of this Series. In lieu of any fractional share
otherwise issuable in respect of all the shares of this Series of any holder
which are redeemed or converted on any redemption date or upon Mandatory
Conversion or any optional conversion, such holder shall be entitled to receive
an amount in cash (computed to the nearest cent) equal to the same fraction of
the (i) Current Market Price in the case of redemption, or (ii) Closing Price of
the Common Stock determined (A) as of the fifth Trading Date immediately
preceding the Mandatory Conversion Date, in the case of Mandatory Conversion,
(B) as of the second Trading Date immediately preceding the effective date of
conversion, in the case of an optional conversion by a holder. If more than one
share shall be surrendered for conversion or redemption at one time by or for
the same holder, the number of full shares of Common Stock issuable upon
conversion thereof shall be computed on the basis of the aggregate number of
shares of this Series so surrendered or redeemed.

     (j)  Reissuance. Shares of this Series that have been issued and reacquired
in any manner, including shares purchased, exchanged, redeemed or converted,
shall not be reissued as part of this Series and shall (upon compliance with any
applicable provisions of the laws of the State of Delaware) have the status of
authorized and unissued shares of the Preferred Stock undesignated as to series
and may be redesignated and reissued as part of any series of Preferred Stock.

               (i)       the term "business day" shall mean any day other than a

                         executive order to close or are closed because of a
                         banking moratorium or otherwise;

               (ii)      the term "Closing Price" on any day shall mean the
                         closing sale price regular way on such day or, in case
                         no such sale takes place on such day, the average of
                         the reported closing bid and asked prices regular
                         way, in each case on the New York Stock Exchange or, if
                         the Common Stock is not listed or admitted to trading
                         on such Exchange, then on the principal national
                         securities exchange on which the Common Stock is listed
                         or admitted to trading (which shall be the national
                         securities exchange on which the greatest number of
                         shares of Common Stock has been traded during the five

                         or quotation system, the average of the closing bid and

                         over-the-counter market on the day in question as
                         reported by the National Quotation Bureau Incorporated,
                         or a similar generally accepted reporting service, or
                         if not so available as determined in good faith by the
                         Board of Directors, on the basis of such relevant
                         factors as it in good faith considers appropriate;

               (iii)     the term "Trading Date" shall mean a date on which the
                         New York Stock Exchange (or any successor thereto) is
                         open for the transaction of business.

     (l)  Payment of Taxes. The Company shall pay any and all documentary, stamp
or similar issue or transfer taxes payable in respect of the issue or deliver of
shares of Common Stock on the redemption or conversion of shares of this Series
pursuant to this paragraph (3); provided, however, that the Company shall not be
required to pay any tax which may be payable in respect of any registration of
transfer involved in the issue or delivery of shares of Common Stock in a name
other than that of the registered holder of shares of this Series redeemed or
converted or to be redeemed or converted, and no such issue or delivery shall be
made unless and until the person requesting such issue has paid to the Company
the amount of any such tax or has established, to the satisfaction of the
Company, that such tax has been paid.

     (m)  Reservation of Common Stock. The Company shall at all times reserve 
and keep available, free from preemptive rights, out of the aggregate of its
authorized but unissued Common Stock and/or its issued Common Stock held in its
treasury, for the purpose of effecting any Mandatory Conversion of the shares of
this Series or any conversion of the shares of this Series at the option of the
holder, the full number of shares of Common Stock then deliverable upon any such
conversion of all outstanding shares of this Series.

     (4)  Liquidation Rights. (a) In the event of the liquidation, dissolution,
or winding up of the business of the Company, whether voluntary or involuntary,
the holders of shares of this Series then outstanding, after payment or
provision for payment of the debts and other liabilities of the Company and the
payment or provision for payment of any distribution on any shares of the
Company having a preference and a priority over the shares of this Series on
liquidation, and before any distribution to the holders of the Common Stock or
any other stock ranking junior to the shares of this Series with respect to
distribution upon liquidation, dissolution or winding up, shall be entitled to
be paid out of the assets of the Company available for distribution to its
stockholders, an amount per share of this Series in cash equal to the sum of (i)
the liquidation value set forth in paragraph (1) above plus (ii) all accrued and
unpaid dividends thereon to the date of liquidation, dissolution or winding up,
before any payment shall be made or any assets distributed to the holders of any
of shares of the Company ranking junior to the shares of this Series upon
liquidation. In the event the assets of the Company available for distribution
to the holders of the shares of this Series upon any dissolution, liquidation or
winding up of the Company shall be insufficient to pay in full the liquidation
payments payable to the holders of outstanding shares of this Series and any
shares of the Company ranking on a

                                     - 14 -

<PAGE>   48

parity with the shares of this Series upon liquidation, then the holders of all
such shares shall share ratably in such distribution of assets in accordance
with the amount which would be payable on such distribution if the amounts to
which the holders of outstanding shares of this Series and the holders of
outstanding shares of such shares of the Company ranking on a parity with the
shares of this Series upon liquidation are entitled were paid in full. Except as
provided in this paragraph (4), holders of this Series shall not be entitled to
any distribution in the event of liquidation, dissolution or winding up of the
affairs of the Company.

     (b)  For the purposes of this paragraph (4), none of the following shall be
deemed to be a voluntary or involuntary liquidation, dissolution or winding up
of the Company:

               (i)       the voluntary sale, conveyance, lease, exchange or
                         transfer (for cash, shares of stock, securities or
                         other consideration) of all or substantially all of the
                         property or assets of the Company;

               (ii)      the consolidation or merger of the Company with or into
                         one or more other corporations, or other associations;

               (iii)     the consolidation or merger of one or more corporations
                         or other associations with or into the Company; or

               (iv)      the participation by the Company in a share exchange.

     (5)       Definition. As used in this Certificate, the term "Common Stock"
shall mean any stock of any class of the Company which has no preference in
respect of dividends or of amounts payable in the event of any voluntary or
involuntary liquidation, dissolution or winding up of the Company and which is
not subject to redemption by the Company. However, shares of Common Stock
issuable upon conversion of shares of this Series shall include only shares of
the class designated as Common Stock as of the original date of issuance of
shares of this Series, or shares of the Company of any class or classes
resulting from any reclassification or reclassification thereof and which have
no preference in respect of dividends or of amounts payable in the event of any
voluntary or involuntary liquidation, dissolution or winding up of the Company
and which are not subject to redemption by the Company; provided that if at any
time there shall be more than one such resulting class, the shares of each
such.) class then so issuable shall be substantially in the proportion which
the total number of shares of such class resulting from such reclassification
bears to the total number of shares of all classes resulting from all such
reclassification.

     (6)       No Preemptive Rights. The holders of shares of this Series shall
  have no preemptive rights, including preemptive rights with respect to any
shares of capital stock or other securities of the Company convertible into or
carrying rights or options to purchase any such shares.

     B.        On June 26, 1993, the Board of Directors adopted certain
resolutions with respect to the authority of the Pricing Committee of the Board
of Directors and fixing the voting rights of the $1.20 Convertible Preferred
Stock as follows:

     RESOLVED, that pursuant to the authority granted and vested in the Board of
Directors, this Board of Directors empowers the Pricing Committee of the Board
of Directors to authorize the issuance of a series (this "Series"), of the
Preferred Stock of the Company (the "Preferred Stock"), which shall consist of
11,500,000 shares, and to fix the powers, designations, preferences and
relative, participating, optional or other special rights, and the
qualifications, limitations or restrictions thereof, other than voting rights,
of the shares of this Series.

     RESOLVED, that this Board of Directors fixes the voting rights of the
shares of this Series as follows:

     (1)  Voting Rights. (a) The holders of shares of this Series shall have the
right with the holders of Common Stock to vote in the election of directors and
upon each other matter coming before any meeting of the stockholders on the
basis of 4/5 of a vote for each share held. The holders of shares of this Series
and the holders of Common Stock shall vote together as one class except as
otherwise set forth herein or as otherwise provided by law or by the Restated
Certificate of Incorporation of the Company.

     (b)  If at any time dividends payable on the shares of this Series are in
arrears and unpaid in an aggregate amount equal to or exceeding the aggregate
amount of dividends payable thereon for six quarterly dividend periods, the
holders of the shares of this Series, together with the holders of any other
series of Preferred Stock then having a right to elect Directors as a result of
a dividend arrearage, shall have the exclusive right (superseding the separate
right of such other series to elect Directors so long as shares of this Series
remain outstanding, except as otherwise expressly provided in the certificate of
designation establishing such other series), voting separately as a class with
any such other series, to elect two Directors of the Company, such Directors to
be in addition to the number of Directors constituting the Board of Directors of
the Company immediately prior to the accrual of such right. Such right of the
holders of shares of this Series to elect two Directors shall, when vested,
continue until all dividends in default on the shares of this Series shall have
been paid in full and, when so paid, such right of the holders of shares of this
Series to elect two Directors separately as a class shall cease, subject,
always, to the same provisions for the vesting of such right of the holders of
the shares of this Series to elect two Directors in the case of future
dividend defaults. At any time when such right to elect such Directors
separately as a class shall have so vested, the Company may, and upon the
written request of the holders of record of not less than 20 percent of the
total number of shares of this Series and such other series of Preferred Stock
then outstanding shall, call a special meeting of the holders of such shares for
the election of Directors to fill such newly-created directorships. In the case
of such a written request, such special meeting shall be held within 90 days
after the delivery of such request and, in either case, at the place and upon
the notice provided by law and in the Bylaws of the Company, provided that the
Company shall not be required to call such a special meeting if such request is
received less than 120 days

                                     - 16 -

<PAGE>   50

before the date fixed for the next ensuing annual meeting of stockholders of the
Company, in which case such newly-created directorships shall be filled by the
holders of such shares of this Series and such other series of Preferred Stock
at such meeting.

     The term of office of each Director elected pursuant to the preceding
paragraph shall terminate on the earlier of (i) the next annual meeting of
stockholders at which a successor shall have been elected and qualified or (ii)
the termination of the right of the holders of shares of this Series and such
other series of Preferred Stock to vote for Directors pursuant to the preceding
paragraph. If, prior to the end of the term of any Director elected as
aforesaid, a vacancy in the office of such Director shall occur, such vacancy
shall be filled for the unexpired term by the appointment by the remaining
Director elected as aforesaid of a new Director for the unexpired term of such
former Director. If both Directors so elected by the holders of shares of this
Series and such other series of Preferred Stock shall cease to serve as
Directors before their terms shall expire, the holders of the shares of this
Series, together with the holders of such other series of Preferred Stock may,
at a special meeting of the holders called as provided above, elect successors
to hold office for the unexpired terms of such Directors whose places shall be
vacant.

     (c)  So long as any shares of this Series remain outstanding, the consent
of the holders of at least two-thirds thereof (voting separately as a class)
given in person or by proxy, at any annual meeting or special meeting called for
such purpose, shall be necessary to amend, alter or repeal any of the provisions
of the Restated Certificate of Incorporation of the Company which would
materially and adversely affect any right, preference, privilege or voting power
of the shares of this Series; provided, however, that any such amendment,
alteration or repeal, that would authorize, create or issue any additional
shares of Preferred Stock or any other shares of stock (whether or not already
authorized) ranking senior to, on a parity with or junior to the shares of this
Series as to dividends or on the distribution of assets upon liquidation,
dissolution or winding up of the affairs of the Company, shall be deemed not to
materially and adversely affect such right, preference, privilege or voting
power and shall not be subject to approval by the holders of shares of this
Series.

     We, Frank M. Hennessey, Chief Executive Officer, and Timothy Wadhams,
Senior Vice President and Assistant Secretary, of MascoTech, Inc., 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 Company, the Board of Directors on
February 17, 1998, 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 250,000. 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 Company.

<PAGE>   62

     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 cash distributions
and 1,000 times the aggregate per share amount of all non-cash dividends or
other noncash distributions (other than (i) a dividend payable in shares of
Common Stock, par value $1.00 per share, of the Company (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 Company shall at any
time after February 17, 1998 (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 Company 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));
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.
        
                                      A-2
<PAGE>   63

     (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 Company. If the Company 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 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 Company.

                                      A-3
<PAGE>   64

     (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 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

                                      A-4
<PAGE>   65

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 Company.
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 Company. 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
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 Company 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

                                      A-5
<PAGE>   66

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 Company 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.

     (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 Company 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 Company may at any time redeem, purchase or otherwise acquire shares of
     any such junior stock in exchange for shares of stock of the Company
     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
        
                                      A-6
<PAGE>   67

as to dividends or upon 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 Company shall not permit any subsidiary of the Company to purchase
or otherwise acquire for value any shares of stock of the Company unless
the Company 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 Company in any manner
whatsoever shall be retired and cancelled 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 the General Corporation Law of the
State of Delaware.
 
     Section 6. Liquidation, Dissolution or Winding Up. Upon any liquidation,
dissolution or winding up of the Company, 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 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
Company 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

                                      A-7
<PAGE>   68

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 Company 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 Company 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 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 Company's preferred stock except any series that specifically provides
that such series shall rank junior to or pari passu with 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.

                             (a Delaware corporation)
                          (As Amended February 17, 1998)


                                     ARTICLE I
                             MEETINGS OF STOCKHOLDERS

      Section 1.01.  Annual Meetings.  The annual meeting of stockholders for
election of Directors and for the transaction of such other proper business,
notice of which was given in the notice of the meeting, shall be held on a date
(other than a legal holiday) in May or June of each year which shall be
designated by the Board of Directors, or on such other date to which a meeting
may be adjourned or re-scheduled, at such time and place within or without the
State of Delaware as shall be designated in the notice of such meeting.
        
      Section 1.02.  Special Meetings.  Except as otherwise required by law,
special meetings of stockholders of the Corporation may be called only by the
Chairman of the Board, the Chief Executive Officer 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. 
Special meetings shall be held at such place within or without the State of
Delaware and at such hour as may be designated in the notice of such meeting and
the business transacted shall be confined to the object stated in the notice of
the meeting.

      Section 1.03.  Re-scheduling and Adjournment of Meetings.  Notwithstanding
Sections 1.01 and 1.02 of this Article, the Board of Directors may postpone and
re-schedule any previously scheduled annual or special meeting of stockholders. 
The person presiding at any meeting is empowered to adjourn the meeting at any
time after it has been convened.    

      Section 1.04.  Notice of Stockholders' Meetings.  The notice of all 
meetings of stockholders shall be in writing and shall state the place, date
and hour of the meeting.  The notice of an annual meeting shall state that the
meeting is called for the election of 
        
<PAGE>   2

the Directors to be elected at such meeting and for the transaction of such
other business as is stated in the notice of the meeting.  The notice of a
special meeting shall state the purpose or purposes for which the meeting is
called and shall also indicate that it is being issued by or at the direction
of the person or persons calling the meeting.  If, at any meeting, action is
proposed to be taken which would, if taken, entitle stockholders fulfilling the
requirements of the General Corporation Law to receive payment for their
shares, the notice of such meeting shall include a statement to that effect.
        
      A copy of the notice of each meeting of stockholders shall be given,
personally or by mail, not less than ten days nor more than sixty days before
the date of the meeting, to each stockholder entitled to vote at such meeting
at his record address or at such other address as he may have furnished by
request in writing to the Secretary of the Corporation.  If a meeting is
adjourned to another time or place, and, if any announcement of the adjourned
time or place is made at the meeting, it shall not be necessary to give notice
of the adjourned meeting unless the adjournment is for more than thirty days or
the Directors, after adjournment, fix a new record date for the adjourned
meeting.
        
      Notice of a meeting need not be given to any stockholder who submits a
signed waiver of notice, in person or by proxy, whether before or after the
meeting.  The attendance of a stockholder at a meeting, in person or by proxy,
without protesting prior to the meeting the lack of notice of such meeting shall
constitute a waiver of notice of the meeting.

      Section 1.05  Business to be Considered.  Only those matters stated to be
considered in the notice of the meeting, or of which written notice has been
given to the Corporation either by personal delivery to the Chairman of the
Board or the Secretary or by U.S. mail, postage prepaid, of a stockholder's
intent to bring the matter before the meeting, may be considered at the Annual
Meeting of Stockholders.  Such notice shall be received no later than 120 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.
        
                                        -2-

      Only that business brought before a special meeting pursuant to the notice
of the meeting may be conducted or considered at such meeting.

      Only such business brought before an annual or special meeting of
stockholders pursuant to these bylaws shall be eligible to be conducted or
considered at such meetings.

      Section 1.06.  Quorum.  Except as otherwise required by law, by the
Certificate of Incorporation or by these bylaws, the presence, in person or by
proxy, of stockholders holding a majority of the stock of the Corporation
entitled to vote shall constitute a quorum at all meetings of the stockholders. 
In case a quorum shall not be present at any meeting, a majority in interest of
the stockholders entitled to vote thereat, present in person or by proxy, shall
have power to adjourn the meeting from time to time, without notice other than
announcement at the meeting, until the requisite amount of stock entitled to
vote shall be present.  At any such adjourned meeting at which the requisite
amount of stock entitled to vote shall be represented, any business may be
transacted which might have been transacted at the meeting as originally
noticed; but only those stockholders entitled to vote at the meeting as
originally noticed shall be entitled to vote at any adjournment or adjournments
thereof.
        
      Directors shall be elected by a plurality of the votes cast at a meeting
of stockholders by the holders of shares entitled to vote in the election. 
Whenever any corporate action, other than the election of Directors, is to be
taken by vote of the stockholders, except as otherwise required by the General
Corporation Law, the Certificate of Incorporation or these bylaws, it shall be
authorized by a majority of the votes cast on the proposal by the holders of
shares entitled to vote thereon at a meeting of stockholders.
        
      Section 1.07.  Inspectors at Stockholders' Meetings.  The Board of
Directors, in advance of any stockholders' meeting, shall appoint one or more
inspectors to act at the meeting or any adjournment thereof and to make a
written report thereof.  In case any inspector or alternate appointed is unable
to act, the person presiding at the meeting shall appoint one or more
inspectors to act at the meeting. Each inspector, before entering upon the
discharge of his duties, shall take and sign an oath faithfully to 
        
                                        -3-

                        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

     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.

                         CORPORATE OPPORTUNITIES AGREEMENT

    This Agreement is made as of December 27, 1988 among Masco Corporation, a
Delaware corporation ("Masco"), Masco Industries, Inc., a Delaware corporation
("Industries") and TriMas Corporation, a Delaware corporation ("TriMas").

    WHEREAS, Industries has agreed, pursuant to an Acquisition and Subscription
Agreement (the "Acquisition Agreement") dated as of November 7, 1988, to
transfer certain businesses and cash to TriMas in exchange for an equity
interest in TriMas and TriMas subordinated debentures;
        
    WHEREAS, Masco has agreed, pursuant to the Acquisition Agreement, to
contribute cash to TriMas in exchange for shares of TriMas common stock, and
proposes thereafter, pursuant to the Acquisition Agreement, to distribute as a
dividend (the "Distribution") a portion of its shares of TriMas common stock to
its stockholders, as a result of which TriMas will become a publicly held
corporation with approximately 48% of its outstanding common stock owned by
Industries and approximately 19% owned by Masco;

    WHEREAS, following the consummation of the transactions set forth in the
Acquisition Agreement and the Distribution, certain of the officers and

may perform or assist TriMas in the performance of a  number of corporate staff
and administrative services, including corporate development functions; and 
        
    WHEREAS, in light of the relationships among Masco, Industries and TriMas,
the parties wish to reduce the potential for conflicts of interest, or the
appearance of conflicts of interest, created by such relationships and to
emphasize the development and growth of their several businesses rather than the
development and growth of competitive product lines;

    NOW, THEREFORE, the parties agree as follows:

    1.    Business Opportunities.

          (a)   Neither TriMas nor any of its subsidiaries shall undertake any
    Third-Party Transaction (as hereinafter defined) which comes to the
    attention of TriMas, Industries or Masco or any of their respective
    subsidiaries if a major portion of the business of the Third-Party
    Transaction entity involves: (i) residential or commercial building or home
    improvement products or services (excluding water supply valves which are
    not of the type currently manufactured or sold by Masco or its subsidiaries
    and which are installed on main water supply

    has been presented to Masco and Industries and thereafter both decline or
    fail, within a reasonable period, to conclude such transaction, (ii) home

    Third-Party Transaction has been presented to Masco and thereafter Masco

    the opportunity to undertake such Third-Party Transaction has been
    presented to Industries and thereafter Industries declines or fails, within
    a reasonable period, to conclude such transaction.
        
          (b)   Neither TriMas nor any of its subsidiaries shall otherwise
    establish a business, the acquisition of which would be subject to the
    provisions of paragraph (a) above, without the consent of Masco, Industries
    or both Masco and Industries, as the case may be.

    2.    Third-Party Transaction.      For purposes of this Agreement, a
"Third-Party Transaction" shall mean any acquisition, merger, consolidation or
joint venture with, investment (other than investments solely in marketable
securities) in or any similar transaction involving a party other than TriMas,
Masco or

Industries, any of their respective subsidiaries or any other entities in which
on the date hereof any of such corporations has investments not consisting
solely of marketable securities.
        
    3.    Prior Agreement.  Nothing herein shall alter the Corporate 
Opportunities Agreement dated as of May 1, 1984 between Masco and Industries,
which shall remain in full force and effect in accordance with its terms.

    4.    Duration.   This Agreement shall continue in effect until the date
which is two years after the termination of the Corporate Services Agreement and
will thereafter be automatically renewed for one-year periods, subjects to the
right of TriMas, Masco or Industries to terminate this Agreement by written
notice which is received by the other parties at least 90 days prior to any
such scheduled renewal date.
        
    5.    Assignability.    This Agreement shall not be assigned by any party,
except to a successor to substantially all of the business of a party, without
the express written consent of the other parties.
        
    6.    Governing Law.    This Agreement shall be governed by and construed in
accordance with the laws of the State of Michigan.

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
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 exercise, 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
        
                                      5
<PAGE>   6
                           
                     (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
              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 Ap- preciation 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 certificates.
        
              (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 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
        

                                      9
<PAGE>   10


                           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;

                             (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 at-
                           tempt 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 
        
                                          10

        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 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 sub- stituted 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  


                                      11
<PAGE>   12

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 ofthe 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.

        (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.
        
                                      13
<PAGE>   14

        (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.

Section 9.  Effective Date of the Plan

Company's stockholders.

        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

        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 sub-
        stitution 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; pro-
vided, 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 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 exercise, such notice to be accompanied by such in-
                struments 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 contin-
                ued.
        
                (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.

                                          6

        (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 certificates.

                (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 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 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
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 continu-
ing 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.

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 Boards 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.

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

      (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.

      (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.

     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) Additional Shares. Shares acquired by the Company in the
     circumstances set forth in (ii) above in excess of the amount set forth
     therein    may thereafter be included in the Shares available for Awards
     to the extent permissible for purposes of allowing the Plan to continue to
     satisfy the conditions of Rule 16b-3.

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

                                       -5-

<PAGE>   6

            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 stock-based Awards under the Plan in
any calendar year that relate to more than 400,000 Shares; 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 years. No provision of
this Paragraph 4(b) shall be

                                       -6-

<PAGE>   7

construed as limiting the amount of any 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, but excluding a member
of the Committee, 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.

                                        -7-

<PAGE>   8

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

                 (A) the purchase price per Share under each Option;

                 (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 
            exercise, 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 shall be made for all Shares then being purchased.

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

                                       -8-

<PAGE>   9

                      (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 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

                                       -9-

<PAGE>   10

            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

                                      -10-
<PAGE>   11

      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.

       (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

                                       -11-

<PAGE>   12

       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 certificates.

            (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.

                                       -12-

<PAGE>   13

                 (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 ac-
                 cordance with Section 6(g)(iv)(B)(1)(c), to such trust; or


                      (2) if the Restricted Period has expired by reason of
                 death and a beneficiary has been designated in a 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

                                       -13-

<PAGE>   14

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

                                       -14-

<PAGE>   15

       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) Except as set forth in Paragraph (2) below, a
                 Participant may assign or transfer an Option or 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;

                                       -15-

<PAGE>   16

                           (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.

                                       -16-

                      (2) 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 (as hereinafter

                                       -17-

<PAGE>   18

       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 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 5,
       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)
            an Affiliated Party (as hereinafter defined); or

                 (2) during any period of twenty-four consecutive calendar
            months, the individuals who at the beginning of

                                       -18-

<PAGE>   19

            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.


            An "Affiliated Party" shall mean (x) MascoTech, Inc., a Delaware
       corporation ("MascoTech"), provided MascoTech then owns at least twenty
       percent of the combined voting power of all voting securities of the
       Company, or (y) Masco Corporation, a Delaware corporation ("Masco"),
       provided Masco then owns (i) at least twenty percent of the combined
       voting power of all voting securities of the Company, or (ii) at least
       twenty percent of the combined voting power of all voting securities of
       MascoTech and MascoTech and Masco Corporation together then own an
       aggregate of at least twenty percent of the combined voting power of all
       voting securities of the Company.

            (C) Notwithstanding the provisions of subparagraph (B), with respect
       to Awards granted hereunder on or after December 5, 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

                                       -19-

<PAGE>   20

       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

                                       -20-

<PAGE>   21

       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.

            (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
outstanding 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.

                                      -21-

<PAGE>   22

       (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(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
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.

                                       -22-

<PAGE>   23

       (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

                                       -23-

<PAGE>   24

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.

Section 9.  Effective Date of the Plan

       The Plan shall be effective as of the date of its approval by the
Company's stockholders.

                                                                   EXHIBIT 10.t

                                TRIMAS CORPORATION

                       1988 RESTRICTED STOCK INCENTIVE PLAN

                            (Restated December 5, 1995)


1.  PURPOSE OF THE PLAN

        The purpose of the Plan is to aid TriMas Corporation (the "Company")
and its subsidiaries and affiliated companies in attracting and retaining key
employees and consultants of outstanding ability.  In addition, the Company
expects that it will benefit from the added interest which such individuals
will have in its welfare as a result of their ownership or increased ownership
of the Company's Common Stock.  For purposes of the Plan a "subsidiary" is any
corporation in which the Company owns, directly or indirectly, stock possessing
more than fifty percent of the total combined voting power of all classes of
stock, and an "affiliated company" is any other corporation, at least twenty
percent of the total combined voting power of all classes of stock of which is
owned by the Company or by one or more other corporations in a chain of
corporations, at least twenty percent of the stock of each of which is held by
the Company or a subsidiary or another corporation within such chain.

2.  STOCK SUBJECT TO THE PLAN

        The shares which may be awarded under the Plan are shares of the
Company's Common Stock, par value $.01 per share.  Subject to adjustment as
provided in Paragraph 6, the total number of shares of the Company's Common
Stock that may be awarded under the Plan shall not exceed 2,000,000; provided,
however, that such number of shares shall be reduced by the number of shares of
the Company's Common Stock as to which options have been granted under the
Company's 1988 Stock Option Plan (other than shares which are available for
further grants under Article IV of such plan notwithstanding the prior grant of
options with respect to such shares).  Such stock may be authorized but
unissued shares or shares reacquired by the Company, including but not limited
to shares purchased on the open market.  Shares of stock awarded under the Plan
which are 

<PAGE>   2

later reacquired by the Company as a result of forfeiture pursuant to the Plan
shall again become available for awards under the Plan.


3.  ADMINISTRATION

        The Plan shall be administered by a committee (the "Committee") of
three or more of the Company's directors to be appointed by the Board of
Directors.  Upon registration of the Company's Common Stock under Section 12 of
the Securities Exchange Act of 1934 (the "Exchange Act"), members of the
Committee shall be "disinterested persons" as such term is defined in Rule
16b-3(d) under the Exchange Act or any rule which modifies, amends or replaces
Rule 16b-3(d).  The Committee shall have the authority, consistent with the
Plan, to determine the terms and conditions of each award, to interpret the
Plan and the agreements entered into pursuant to the Plan, to adopt, amend
and rescind rules and regulations for its administration and the awards, and
generally to conduct and administer the Plan and to make all determinations in
connection therewith which may be necessary or advisable, and all such actions
of the Committee shall be conclusive and binding upon all parties concerned.

4.  ELIGIBILITY

        Key employees of and consultants to the Company and its subsidiaries
and affiliated companies, including officers of the Company (who may also be
directors, but excluding members of the Committee, any person who serves only
as a director of the Company and any consultant to the Company or any of its
subsidiaries or affiliated companies who is also a director of the Company or
who is not rendering services pursuant to a written agreement with the
corporation in question), as may be selected from time to time by the Committee
in its discretion, are eligible to receive awards under the Plan.  The
Committee shall determine in its sole discretion the number of shares to be
awarded to each participant.

5.  TERMS AND CONDITIONS OF AWARDS

        All shares of Common Stock awarded to participants shall be subject to
the following terms and conditions, and to such 


                                     -2-

<PAGE>   3

other terms and conditions not inconsistent with the Plan as shall be
contained in each Award Agreement ("Agreement") referred to in Paragraph 5(f):

            (a)  At the time of each award there shall be established for the
      shares of each participant a "Restricted Period" which shall be not
      less than ninety days.  Such Restricted Period may differ among
      participants and may have different expiration dates with respect to
      portions of shares covered by the same award.  The Committee may also
      determine that the expiration of any Restricted Period shall be subject
      to such additional terms and conditions as it decides in its sole
      discretion and as set forth in the participant's Agreement.

            (b)  Shares of Common Stock awarded to participants may not be sold,
      encumbered or otherwise transferred, except as hereinafter provided,
      during the Restricted Period pertaining to such shares.  Except for such
      restrictions on transfer, the participant shall have all the rights of
      a stockholder including but not limited to the right to receive all
      dividends paid on such shares (subject to the provisions of Paragraph 6)
      and the right to vote such shares.

            (c)  If a participant ceases to be employed or retained by the 
      Company or any of its subsidiaries or affiliated companies for any
      reason (including termination by reason of the fact that any corporation
      is no longer a subsidiary or affiliated company), other than death,
      permanent and total disability, or, in the case of an employee,
      retirement on or after normal retirement date, all shares of stock
      theretofore awarded to the participant which are still subject to the
      restrictions imposed by Paragraph 5(b) shall upon such termination of
      employment or the consulting relationship be forfeited and transferred
      back to the Company, provided, however, that if such employment or
      consulting relationship is terminated by action of the Company or any of
      its subsidiaries or affiliated companies without cause or by agreement of
      the Company or any of its subsidiaries or affiliated companies and the
      participant, the Committee may, but need not, determine that some or all
      of the shares shall not be so forfeited, and provided further that the
      Committee may remove or modify restrictions on shares which are not
      forfeited.  For purposes of this Paragraph 5(c), a participant's
      employment or consulting arrangement shall not 

                                    -3-
<PAGE>   4

      be considered terminated (i) in the case of transfers of employment or
      the consulting arrangement among the Company, its subsidiaries and
      affiliated companies, (ii) by virtue of a change of status from employee
      to consultant or from consultant to employee, or (iii) in the case of
      interruption in service, not exceeding one year in duration unless
      otherwise approved by the Committee, for approved sick leave or other
      bona fide leave of absence.

            (d)  If a participant ceases to be employed or retained by the 
      Company or any of its subsidiaries or affiliated companies by reason of
      death or permanent and total disability or if an employee ceases to be
      employed by the Company or any of its subsidiaries or affiliated
      companies by reason of retirement on or after normal retirement date, the
      restrictions imposed by Paragraph 5(b) shall lapse with respect to the
      shares then subject to restrictions, except to the extent provided to the
      contrary in the Agreement.

            (e)  Shares of Common Stock awarded under the Plan shall not be
      evidenced by certificates until restrictions lapse but shall be registered
      in the name of the participant in book entry form in the Company's stock
      register.
            
            (f)  The participant shall enter into an Agreement with the 
      Company in a form specified by the Committee agreeing to the terms and
      conditions of the award, the expiration of the Restricted Period as to
      the shares covered by the award, and such other matters, including
      compliance with applicable federal and state securities laws and methods
      of withholding or providing for the payment of required taxes, as the
      Committee in its sole discretion shall determine.  The Committee may at
      any time amend the terms of any Agreement consistent with the terms of
      the Plan, except that without the participant's written consent no such
      amendment shall adversely affect the rights of the participant.

            (g)  At the expiration of the Restricted Period as to shares 
      covered by any award, the Company shall redeliver the stock
      certificates deposited with it pursuant to Paragraph 5(e) and as to
      which the Restricted Period has expired, as follows:

                  (1)  if an assignment to a trust has been made in accordance
            with Paragraph 5(i), 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.

      Upon written request, the Company will instruct its stock transfer agent
      that such certificates may be reissued without legend.

            (h) (1) Notwithstanding any of the provisions of this Plan or
      instruments evidencing awards granted hereunder, in the case of a Change 
      in Control of the Company, each award theretofore granted shall
      immediately become fully vested and non-forfeitable and shall thereupon
      be distributed to participants as soon as practicable, free of all
      restrictions.  A Change in Control shall occur if any of the events
      described below in subparagraphs (A), (B) or (C) shall have occurred,
      unless the holder of any such award shall have consented to the
      application of subparagraph (C) in lieu of subparagraphs (A) and (B):

                 (A)  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 directly or indirectly purchases or otherwise
            becomes the "beneficial owner" (as defined in Rule 13d3 under the
            Exchange Act) or has the right to acquire such beneficial ownership
            (whether or not such 

                                     -5-

            right is exercisable immediately, with the passage of time, or
            subject to any condition), of voting securities representing
            twenty-five percent or more of the combined voting power of
            all outstanding voting securities of (A) the Company, or (B) of an
            Affiliated Party (as hereinafter defined); 

                 (B) 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; or

                 (C) 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 

                                     -6-

<PAGE>   7


            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.

      An "Affiliated Party" shall mean (x) MascoTech, Inc., a Delaware 
      corporation ("MascoTech"), provided MascoTech then owns at least twenty
      percent of the combined voting power of all voting securities of the
      Company, or (y) Masco Corporation, a Delaware corporation ("Masco"),
      provided Masco then owns (i) at least twenty percent of the combined
      voting power of all voting securities of the Company, or (ii) at least
      twenty percent of the combined voting power of all voting securities of
      MascoTech and MascoTech then owns at least twenty percent of the combined
      voting power of all voting securities of the Company.

            (2)(A) 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 (2) (a "Payment"), would be
      subject to the excise tax imposed by Section 4999 of the Internal Revenue
      Code of 1986, as amended from time to time (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 (B) 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.


                                     -7-


<PAGE>   8


            (B)   All determinations required to be made under this Section
      5(h)(2), 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.

            (C)   This Section 5(h)(2) 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.

            (i)  Notwithstanding any other provision of this Plan, a participant
      may assign all rights under any award to a revocable grantor trust
      established by the participant for the sole benefit of the participant
      during the life of the participant, 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 in-
      strument in form and content satisfactory to the Committee and the
      participant shall 

                                     -8-


<PAGE>   9


      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 an award does not
      meet the criteria of a trust to which an assignment is permitted by the
      terms of this paragraph, 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 awards shall
      revert to and remain solely in the participant.  Notwithstanding a
      qualified assignment, the participant, and not the trust to which rights
      under 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,
      a subsidiary or affiliated company, but such trust and the participant
      shall be bound by all of the terms and conditions of the Agreement and
      this Plan.

            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, his personal representatives
      and all persons asserting a claim based on an award granted pursuant to
      this Plan.  The delivery by a participant of a beneficiary designation,
      or an assignment of rights under an award as permitted by this Paragraph
      5(i), 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 upon 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.  Issuance
      of shares as to which restrictions have lapsed in the name of, and
      delivery to, 


                                     -9-


<PAGE>   10


      the trust to which rights may be assigned shall be conclusively
      considered issuance and delivery to the participant.

            (j)  The Committee, in its discretion and in accordance with its
      procedures, may permit the participant to satisfy, in whole or in part, 
      the applicable income tax withholding obligations when the restrictions
      imposed by Paragraph 5(b) lapse by having shares withheld from the shares
      as to which the Restricted Period has expired or by delivering shares of
      Common Stock of the Company having a fair market value equal to the
      amount needed to satisfy such obligations.

            (k)  In its sole discretion the Committee may also provide the
      participant with the right to receive cash payments in connection with
      shares of Common Stock awarded under the Plan (including shares previously
      awarded), the amount of which payments are based, in whole or only in
      part, on the value of such Common Stock.  The right to receive such
      payments shall be subject to such other terms and conditions not
      inconsistent with the Plan as the Committee may determine.

6.  CHANGES IN CAPITALIZATION

        If there is a change in, reclassification, subdivision or combination
of, stock dividend on, or exchange of stock by the Company for the outstanding
Common Stock of the Company, the maximum aggregate number and class of shares
as to which awards may be granted under the Plan shall be appropriately
adjusted by the Committee whose determination thereof shall be conclusive. 
Unless the Committee shall otherwise determine, any shares of stock or other
securities received by a participant with respect to shares still subject to
the restrictions imposed by Paragraph 5(b) will be subject to the same
restrictions and shall be deposited with the Company.

        If the Company shall be consolidated or merged with another
corporation, the stock, securities or other property which a participant is
entitled to receive by reason of his ownership of the shares of stock subject
to the restrictions imposed pursuant to Paragraph 5(b) shall be subject to the


                                    -10-
<PAGE>   11


same or equivalent restrictions unless the Committee shall determine otherwise
at that time.

7.  AMENDMENT OF THE PLAN

        The Board of Directors may from time to time amend or discontinue the
Plan, except that without the approval of the Company's stockholders no
amendment shall increase the number of shares which may be awarded under the
Plan, extend the date for awards of shares under the Plan beyond December 31,
1998 or change the standards of eligibility of employees or consultants
eligible to participate in the Plan.  The number of shares awardable under the
Plan may, however, without stockholder approval, be adjusted pursuant to the
adjustment provisions described in Paragraph 6 hereof.

8.  EMPLOYMENT RIGHTS

        The adoption of the Plan, the award of stock hereunder and the
participation by a participant in the Plan do not confer upon any employee of
or consultant to the Company or a subsidiary or an affiliated company any right
to continue the employment or consulting relationship with the Company or a
subsidiary or an affiliated company, as the case may be, nor does it in any way
impair the right of the Company or a subsidiary or an affiliated company to
terminate the employment of any of its employees or the consulting arrangement
with any of its consultants at any time, with or without cause, unless a
written employment or consulting agreement provides otherwise.

9.  EFFECTIVE DATE AND TERMINATION OF AWARDS

      The Plan shall become effective when approved by the stockholders of the
Company and no shares may be awarded under the Plan after December 31, 1998.

                              February 28, 1995
          

          
       
                    
          
Dear      :
          
      As you know, our company's Board of Directors has adopted a Plan whereby
supplemental retirement and other benefits, in addition to those provided under
the Company's pension and other benefit plans, will be made available to those
Company and subsidiary executives as may be designated from time to time by the 
company's Chief Executive Officer.  You have been previously designated as a
participant in the Plan by a letter agreement signed by you and dated February
14, 1994.  This agreement amends and replaces in its entirety your previously
signed letter agreement and describes in full your benefits pursuant to the
Plan and all of the Company's obligations to you and yours to the Company under
the Plan.  These benefits as described below are contractual obligations of the
Company.

     For the purposes of this Agreement, words and terms are defined as follows:

            a.   "Retirement" shall mean your termination of employment with the
      Company, on or after you attain age 65.  Your acting as a consultant shall

      three years' total annual cash compensation paid to you by the Company,
      consisting of (i) base salaries and (ii) regular year-end cash bonuses
      paid with respect to the years in which such salaries are paid, divided
      by three.
     
            c.   If you become Disabled, "Total Compensation" shall mean your
      annual base salary rate in the year in which you become Disabled plus the
      regular year-end cash bonus paid to you for the year immediately prior
      thereto.
     
            d.   "Surviving Spouse" shall be the person to whom you shall be
      legally married (under the law of the jurisdiction of your permanent
      residence) at the date of (i) your Retirement or death after attaining age
      65 (if death

                              Page 2                           February 28, 1995


      terminated employment with the Company) for the purposes of paragraphs 1,
      2 and 3, (ii) your death for the purposes of paragraph 5, and (iii) your
      Disability for the purposes of paragraphs 6 and 7.  For the purposes of   
      paragraphs 10a, 10e, 10f, 10g and 10h, "Surviving Spouse" shall be any
      spouse entitled to survivor's benefits.

            e.   "Disability" and "Disabled" shall mean your being unable to
      perform your duties as a Company executive by reason of your physical or
      mental condition, prior to your attaining age 65, provided that you have
      been employed by the Company for two consecutive Years or more.
     
            f.   "Company" shall mean TriMas Corporation or any corporation in
      which TriMas Corporation or a subsidiary owns stock possessing at least
      20% of the total combined voting power of all classes of stock.
     
            g.   "Year" shall mean twelve full consecutive months, and "year"
      shall mean a calendar year.

            h.   "Plan Limitation" for any year shall mean (x) for 1989, 
      $300,000 multiplied by the Cost of Living Factor for 1988, and (y) for any
      year subsequent to 1989, the Plan Limitation for the immediately
      preceding year multiplied by the Cost of Living Factor for such preceding
      year.

            i.   "Cost of Living Factor" for any year shall mean, except as
      otherwise provided generally with respect to the Plan by the Company's
      Board of Directors, the quotient (in no event to exceed 1.03 or to be
      less than .97) obtained by dividing the monthly Consumer Price Index
      Number (as compiled in the Consumer Price Index for Urban Consumers by the
      Bureau of Labor Statistics) for the month of December in such year by the
      monthly Consumer Price Index Number for the immediately preceding month of
      December.

            j.   A "Change in Control" shall be deemed to have occurred 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 whose election by such Board or
      nomination for election by stockholders was approved by a vote of at

                                   Page 3                    February 28, 1995


      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.     

      1.   In accordance with the Plan, upon your Retirement the Company will 
pay you annually during your lifetime 60% of your Average Compensation, less: 
(i) a sum equal to the annual benefit which would be payable to you upon your
Retirement if benefits payable to you under the Company funded qualified
pension plans and the defined benefit (pension) plan restoration provisions of
the Company's Retirement Benefits Restoration Plan and any similar plan were
converted to a life annuity, or if you are married when you retire, to a joint
and spouse survivor life annuity, (ii) a sum equal to the annual benefit which
would be payable to you  upon Retirement if your vested accounts in the
Company's Future Service Profit Sharing Trust and the defined contribution
(profit sharing) restoration provisions of the Company's Retirement Benefits
Restoration Plan and any similar plan were converted to a life annuity, and
(iii) any retirement benefits payable to you by reason of employment by your
prior employers (excluding, however, from such deduction any portion thereof,
and earnings thereon, determined by the committee referred to in paragraph 10
to have been contributed by you rather than your prior employers).  In all
cases the amount offset pursuant to these subsections (i) and (ii) shall be
determined prior to the effect of any payments from the plans and trust
referred to therein which are authorized pursuant to a Qualified Domestic
Relations Order under ERISA.

     2.    Upon your death after Retirement or while employed by the Company 
after attaining age 65, your Surviving Spouse shall receive for life 75% of the
annual  benefit pursuant to paragraph 1 of this Agreement which was payable to
you prior to your death (or, if death terminated employment after attaining age
65, which would have been payable to you had your Retirement occurred
immediately prior to your death).

     3.    Upon your Retirement the Company will provide or

                                   Page 4                  February 28, 1995




purchase for you and your spouse's benefit, or at its option reimburse you or
your Surviving Spouse for premiums paid, during your joint and several lives,
such supplemental medical insurance as the Company may deem advisable from time
to time.

      4.  Under no circumstances (i) will any retirement benefits be paid to 
you or your Surviving Spouse pursuant to this Agreement unless you were employed
by the Company or Disabled on your Retirement, or were employed by the
Company at the time of your death after attaining age 65, and (ii) will you or
your Surviving Spouse be entitled to receive retirement benefits under this
Agreement if your Retirement commences prior to your attaining age 65.

     5.   If while employed by the Company you die prior to your attaining 
age 65 leaving a Surviving Spouse, and provided you shall have been employed by
the Company for two consecutive Years or more, your Surviving Spouse shall
receive annually for life 45% of your Average Compensation, less:  (i) a sum
equal to the annual benefit which would be payable to your Surviving Spouse
under Company funded qualified pension plans and the defined benefit (pension)
plan  restoration provisions of the Company's Retirement Benefits Restoration
Plan and any similar plan if such benefit were converted to a life annuity, and
(ii) a sum equal to the annual payments which would be received by your
Surviving Spouse as if your spouse were designated as the beneficiary of your
vested accounts in the Company's Future Service Profit Sharing Trust and the
defined contribution (profit sharing) restoration provisions of the Company's
Retirement Benefits Restoration Plan and any similar plan and such accounts were
converted to a life annuity.  In all cases the amount offset pursuant to these
subsections (i) and (ii) shall be determined prior to the effect of any payments
from the plans and trust referred to therein which are authorized pursuant to a
Qualified Domestic Relations Order under ERISA.  No death benefits are payable
except to your Surviving Spouse.

     6.   If you shall have been employed by the Company for two Years or more
and while employed by the Company you become Disabled prior to your
attaining age 65, until the earlier of your death, termination of Disability or
attaining age 65 the

Company will pay you an annual benefit equal to 60% of your Total Compensation  
less any benefits payable to you pursuant to long-term disability insurance or
other plans the cost of which is paid by the Company.  If your Disability
continues until you attain age 65, you shall be considered retired and you shall
receive retirement benefits pursuant to paragraph 1 above, based upon your
Average Compensation as of the date it is determined you became Disabled.


     7.   If you die leaving a Surviving Spouse while receiving Disability
benefits pursuant to paragraph 6 of this Agreement, notwithstanding paragraph 4 
you will be deemed to have retired on your death and your Surviving Spouse shall
receive for life 75% of the annual benefit which would have been payable to you
if you had retired on the date of your death and your benefit determined
pursuant to paragraph 1, based upon your Average Compensation as of your
becoming Disabled.

     8.   Notwithstanding any of the provisions of this Agreement, the maximum
retirement, disability and death benefits payable to you and your spouse
pursuant to this Agreement for any year shall in no event exceed the higher of
(A) $500,000 less those sums to be deducted from benefits pursuant to clauses
(i),  (ii) and  (iii) of paragraph 1, clauses (i) and (ii) of paragraph 5, or
under paragraph 6, whichever is applicable, or (B) the Plan Limitation for the
year in which such benefits were first paid, less the aggregate annual benefit
with respect to the Company's Retirement Benefits Restoration Plan (and any
future non-qualified retirement plan) to be deducted (x) under clauses (i) and
(ii) of paragraph 1, (y) under paragraph 5 should you die while employed prior
to attaining age 65 or (z) under paragraph 6 should you become disabled prior to
attaining age 65. 

     9.   If you are eligible to receive benefits hereunder, unless otherwise
specifically agreed by the Company in writing, you will not be able to receive
benefits under any other Company sponsored non-qualified retirement plans other
than the Company's Retirement Benefits Restoration Plan.

     10.  We also agree upon the following:

            a.   The Compensation Committee of the company's

                                  Page 6                    February 28, 1995


      Board of Directors, or any other committee however titled which shall be
      vested with authority with respect to the compensation of the company's
      officers and executives, shall have the exclusive authority to make all
      determinations which may be necessary in connection with this Agreement
      including the date of and whether you are Disabled, the amount of annual
      benefits payable to you by reason of employment by other employers, the
      interpretation of this Agreement, and all other matters or disputes
      arising under this Agreement.  The determinations and findings of the
      Compensation Committee or such other committee of the company's Board
      of Directors shall be conclusive and binding, without appeal, upon both of
      us.
     
            b.   You will not during your employment or Disability, and after
      Retirement or the termination of your employment, for any reason disclose
      or make use of for your own or another person's benefit under any
      circumstances any of the Company's Proprietary Information. 
      Proprietary Information shall include trade secrets, secret processes,
      information concerning products, developments, manufacturing techniques,
      new product or marketing plans, inventions, research and development
      information or results, sales, pricing and financial data, information
      relating to the management, operations or planning of the Company and any
      other information treated as confidential or proprietary.
     
            c.   If your employment by the Company shall terminate for any 
      reason whatsoever prior to your Retirement other than by reason of your
      death or  Disability, for a period of two years after the termination of
      your employment, and if your employment shall be terminated by reason of
      Retirement or any Disability during such time as you shall receive
      retirement or disability benefits pursuant to this Agreement, you agree
      that you will not directly or indirectly engage in any business
      activities, whether as a consultant, advisor or otherwise, in which the
      Company is engaged in any geographic area in which the products or
      services of the Company have been sold, distributed or provided during the
      five year period prior to the date of termination of employment or
      Retirement.

      In addition to the foregoing and provided no "Change in

      Control" has occurred, if while you are receiving retirement or other
      benefits pursuant to this Agreement, in the judgment of the committee you
      directly or indirectly engage in activity or act in a manner which can be
      considered adverse to the interest of the Company or any of its direct or
      indirect subsidiaries or affiliated companies, the committee may terminate
      your rights to any further benefits hereunder.
     
            d.   Except as may be provided to the contrary in a duly authorized
      written agreement between yourself and the Company you acknowledge that
      the Company has made no commitments to you of any kind with respect to    
      the continuation of your employment, which we expressly agree is an
      employment at will, and you or the Company shall have the unrestricted
      right to terminate your employment with or without cause, at any time in
      your or its discretion.
     
            e.   At the Company's request, expressed through a Company officer,
      you agree to provide such information with respect to matters which may   
      arise in connection with this Agreement as may be deemed necessary by the 
      Company or the Compensation or other committee, including for example 
      only and not in limitation, information concerning benefits payable to 
      you from third parties, and you further agree to submit to such medical
      examinations by duly licensed physicians as may be requested by the
      Company or such committee from time to time.  You also agree to direct
      third parties to provide such information, and your Surviving Spouse's
      cooperation in providing such information is a condition to the receipt of
      survivor's benefits under this Agreement.
     
            f.   To the extent permitted by law, no interest in this Agreement
      or benefits payable to you or to your Surviving Spouse shall be
      subject to anticipation, or to pledge, assignment, sale or transfer in any
      manner nor shall pledge, assignment, sale or transfer in any manner
      nor shall you or your Surviving Spouse have the power in any
      manner to charge or encumber such interest or benefits, nor shall such
      interest or  benefits be liable or subject in any manner for the
      liabilities of you  or your Surviving Spouse's debts, contracts, torts or
      other engagements  of any kind.

            g.   No person other than you and your Surviving Spouse shall have 
      any rights or property interest of any kind whatsoever pursuant to this   
      Agreement, and neither you nor your Surviving Spouse shall have any rights
      hereunder other than those expressly provided in this Agreement.  Upon the
      death of you and your Surviving Spouse no further benefits of whatsoever
      kind or nature shall accrue or be payable pursuant to this Agreement.

            h.   All benefits payable pursuant to this Agreement shall be paid 
      in installments of one-twelfth of the annual benefit, or at such
      shorter intervals as may be deemed advisable by the Company in its        
      discretion, upon receipt of your or your Surviving Spouse's written
      application, or by the applicant's personal representative in the event of
      disability.
     
            i.   All benefits under this Agreement shall be payable from the
      Company's general assets, which assets are subject to the claims of 
      general creditors, and are not set aside for your or your Surviving 
      Spouse's benefit.
     
            j.   This Agreement shall be governed by the laws of the State of
      Michigan.
     
      11.  We have agreed that the determinations of the committee described in
paragraph 10a shall be conclusive as provided in such paragraph, but if for any
reason a claim is asserted which subverts the provisions of paragraph 10a, we
agree that, except for causes of action which may arise under paragraph 10b and
the first paragraph of paragraph 10c, arbitration shall be the sole and
exclusive remedy to resolve all disputes, claims or controversies which could be
the subject of litigation (hereafter referred to as "dispute") involving or
arising out of this Agreement.  It is our mutual intention that the arbitration
award will be final and binding and that a judgment on the award may be entered
in any court of competent jurisdiction and enforcement may be had according to
its terms.

     The arbitrator shall be chosen in accordance with the commercial
arbitration rules of the American Arbitration

                                Page 9                     February 28, 1995


Association and the expenses of the arbitration shall be borne equally by the 
parties to the dispute.  The place of the arbitration shall be the principal 
offices of theAmerican Arbitration Association in the metropolitan Detroit area.

     The arbitrator's sole authority shall be to apply the clauses of this
Agreement.


     We agree that the provisions of this paragraph 11, and the decision of the
arbitrator with respect to any dispute, with only the exception provided in this
paragraph 11, shall be the sole and exclusive remedy for any alleged cause of
action in any manner based upon or arising out of this Agreement.  Subject to
the foregoing exception, we acknowledge that since arbitration is the
exclusive remedy, neither of us or any party claiming under this Agreement has
the right to resort to any federal, state or local court or administrative
agency concerning any matters dealt with by this Agreement and that the decision
of the arbitrator shall be a complete defense to any action or proceeding
instituted in any tribunal or agency with respect to any dispute.  The
arbitration provisions contained in this paragraph shall survive the termination
or expiration of this Agreement, and shall be binding on our respective
successors, personal representatives and any other party asserting a claim based
upon this Agreement.

     We further agree that any demand for arbitration must be made within one 
year of the time any claim accrues which you or any person claiming hereunder
may have against the Company;  unless demand is made within such period it is
forever barred.

     We are pleased to be able to make this supplemental plan available to you. 
Please examine the terms of this Agreement carefully and at your earliest       
convenience indicate your assent  to all of its terms and conditions by signing
and dating where provided below and returning a signed copy to me.

                           TRIMAS CORPORATION RETIREMENT
                             BENEFIT RESTORATION PLAN






                                     SECTION l
                                 ADOPTION OF PLAN



          1.1   Adoption.  TriMas Corporation (TriMas) hereby adopts the TriMas
Corporation Retirement Benefit Restoration Plan (Plan), effective January 1,
1995 (Effective Date).

          1.2   Purpose.  The sole purpose of the Plan is to provide benefits to
a select group of management or highly compensated employees that would be
provided to such employees who terminate employment or retire after the
Effective Date under certain retirement plans of TriMas Corporation and
its subsidiaries, which plans are set forth in Appendix "A" hereto and are
qualified plans under Section 401(a) of the Internal Revenue Code of 1986, as
amended (Code) (the "Qualified Plans"), but for the benefit limitations of the
Code, in order to encourage the continued employment and diligent service of
such employees with TriMas following the Effective Date.  Accordingly (by way
of example and not limitation), in no event shall the provisions of the Plan be
construed to benefit any employee whose termination of employment occurred
prior to the Effective Date.

          1.3   Construction.  The Plan shall be construed in accordance with
Michigan law, except where preempted by federal law.  It is intended that the
Plan  shall be unfunded and maintained by TriMas primarily for the purpose of
providing deferred compensation for a select group of management or highly
compensated employees, so that the Plan is exempt from the requirements of
Parts 2, 3 and 4 of the 

<PAGE>   2

Employee Retirement Income Security Act of 1974, as amended (ERISA).  All
provisions of the Plan shall be interpreted in accordance with such intentions.

                                  SECTION 2
                                  COVERAGE



          2.1   Covered Employees.  The coverage of the Plan shall be limited to
highly-compensated or management employees of TriMas and of those subsidiaries
of TriMas the Qualified Plans of which are listed in Appendix "A", who (a)
receive from TriMas or the subsidiary of TriMas which is the employer of such
person compensation otherwise eligible for coverage under the terms of such
Qualified Plan for any calendar year which compensation exceeds $150,000 or
such other adjusted limit as provided by Section 401(a)(17) of the Code, or (b)
whose benefits or contributions under the Qualified Plans are reduced due to
the application of Section 415 of the Code.

          2.2   Commencement and Cessation of Coverage.  An employee shall be
covered under the Plan commencing on the later of (a) the Effective Date or (b)
the earlier of the date that his plan-eligible compensation described in
Section date his benefits or contributions under the Qualified Plans are first
reduced by the application of Code Section 415.  An employee shall cease to be
covered by the Plan on his date of termination of employment from TriMas and
its subsidiaries.  If prior to such termination an employee ceases to qualify
for coverage under the Plan due to some other event (by way of examples and not
as limitation, a decrease in Plan-eligible compensation or the commencement of
employment with a TriMas subsidiary which has no Qualified Plan or has
discontinued its Qualified Plan), his coverage under the Plan shall cease as of
the time such disqualifying event occurs and only the benefits accrued
hereunder up to such time shall be payable from this Plan.

                                     SECTION 3
                                     BENEFITS



          3.1   Amount.  Subject to Section 3.3 hereof, a covered employee shall
be entitled to either or both, as applicable, the supplemental retirement
benefits described below:

                (a) An annual amount equal to the benefit which would have been
          payable to the employee under any defined benefit (pension) Qualified
          Plan in which he is a participant ("Qualified Pension Plan") but for
          any benefit limitations imposed by the Code on the computation of such
          benefit, reduced (but not below zero) by

                (b) any benefits which the employee is eligible to receive, 
          prior to the giving effect to any qualified domestic relations order,
          under any such Qualified Pension Plan,

each benefit being expressed for this purpose in the normal form of payment
under said Qualified Pension Plan, plus

                (c) A single lump sum payment equal to the sum of amounts which
          would have been contributed to the account of the employee as a
          company contribution with respect to periods after December 31, 1993 
          under any defined contribution (profit sharing) Qualified Plan in
          which he is a participant (but in no case including any amounts,
          however characterized, which the employee or the company may have
          contributed to any such plan pursuant to the provisions of Section
          401(k) or 401(m) of the Code) ("Qualified Profit Sharing Plan") but
          for any benefit limitations imposed by the Code on the contribution
          amount, plus

                (d) investment adjustments applied to the contribution
          amounts of Section 3.1(c) which 

                                     -4-

<PAGE>   5


          adjustments shall be applied to such accounts (i) utilizing
          the same provisions for calculating the effect of investment earnings
          (or losses) as prevail under the terms of any such Qualified
          Profit Sharing Plan and (ii) utilizing the amount of investment
          earnings (or loss) as is experienced in a given year in the TriMas
          Master Profit Sharing Trust or other investment vehicle in which the 
          assets of any such Qualified Profit Sharing Plan are invested (and in
          no case applying any adjustments for forfeitures of any kind) reduced
          (but not below zero) by

                (e) the covered employee's account balance attributable to
          company profit sharing contributions made with respect to periods
          after December 31, 1993 which the employee is eligible to receive,
          prior to the giving effect to any qualified domestic relations
          order, under any such Qualified Profit Sharing Plan,

provided, however, that any lump sum payment made pursuant to this Plan shall
have no adjustment the purpose of which is to make such payment equivalent
after the effect of any taxes which may have to be paid by the employee
because such lump sum payments from this Plan are taxable when received as
ordinary income and may not be eligible for rollover or other tax-advantaged
treatment under the Code.
 
          3.2   Timing and Form of Payments. (a) Retirement benefit payments
hereunder which are supplemental to a Qualified Pension Plan shall be made at
the same time as benefit payments are made from the Qualified Pension Plan and
shall be payable (i) for an employee who is unmarried at the time payments
commence, in the form of a single life annuity, or (ii) for any employee who is
married when payments commence, in the form of a 50% joint and survivor annuity
with the employee's spouse, unless, in either case, the employee validly elects
another form of payment for benefits under the Qualified Pension Plan, in which
case the supplemental retirement benefit hereunder shall be paid in the same
form as benefits are paid under the Qualified 

                                     -5-

<PAGE>   6

Pension Plan, computed using the same formulas and actuarial factors as
set forth for the determination of optional forms of benefits under such plan;
for purposes of this Section 3.2(a), an employee's marital status and spouse
shall be determined in accordance with the Qualified Pension Plan.

          (b)  Retirement benefit payments hereunder which are supplemental to a
Qualified Profit Sharing Plan shall be payable in a lump sum and shall be made
at the time and to the same person as the lump sum payment is made from
the Qualified Profit Sharing Plan.

          3.3   Forfeitability.  Payment of benefits under the Plan shall be
conditioned upon receipt of benefit payments from the respective Qualified Plans
and shall be vested in the same manner and to the same extent as benefits under
such Qualified Plans.

          3.4  No Payment During Employment.  Notwithstanding the foregoing, no
periodic payments computed under paragraphs (a) and (b) of Section 3.1 of this  
Plan shall be made during such time as any person both receives payments from
any Qualified Plan and is employed by TriMas or any affiliated company, and no
lump sum payment computed under paragraphs (c), (d) and (e) of Section 3.1 of
this Plan shall be made until after the covered employee's termination of
employment.

                                  SECTION 4
                              COST OF BENEFITS



          4.1   Current Expense.  The entire cost of providing benefits under 
the Plan, including the costs of the Plan Administrator, shall be paid by
TriMas out of its current operating budget, and TriMas's obligations under the
Plan shall be an unfunded and unsecured promise to pay.  TriMas shall not be
obligated under any circumstances to separately fund its obligations under the
Plan.

          4.2   Option to Fund Informally.  Notwithstanding Section 4.1, TriMas
may, at its sole option, or by agreement, informally fund its obligations under
the Plan in whole or in part, provided, however, in no event shall such
informal funding be construed to create any trust fund, escrow account
or other security for an employee with respect to the payment of benefits under
the Plan, other than as permitted under Internal Revenue Service and Department
of Labor rules and regulations for unfunded supplemental retirement plans. 
Furthermore, if TriMas decides to informally fund the Plan, in whole or in
part, by procuring, as owner, life insurance for its own benefit on the lives
of employees, the form of such insurance and the amounts thereof shall be the
sole decision of TriMas, and in no event shall an employee have any incidents
of ownership in any such policies of insurance.

          4.3   Physical Examinations.  If a physical examination is required
for TriMas to obtain insurance for covered employees under Section 4.2, each
employee agrees to undergo such physical examinations as may be required
by the insurance carrier.  Such physical examinations shall be conducted by a
physician approved by TriMas, at the expense of TriMas.

          4.4   No Employee Contributions or Loans.  No loans 

                                     -7-
<PAGE>   8


or hardship distributions or contributions by employees are permitted or
required under the Plan.

                                  SECTION 5
                               ADMINISTRATION



          5.1   Plan Administrator and Named Fiduciary.  The Plan Administrator
and Named Fiduciary of the Plan for purposes of ERISA shall be TriMas
Corporation whose business address is 315 East Eisenhower Parkway, Ann
Arbor, MI 48108, and whose telephone number is (313) 747-7025.  TriMas shall
have the right to change the Plan Administrator and Named Fiduciary of the Plan
at any time, and to change the address and telephone number of the same. 
TriMas shall give each covered employee written notice of any such change in
the Plan Administrator and Named Fiduciary, or in the address or telephone
number of the same.

          5.2   Claims Procedure.  The Plan Administrator has the power to
interpret all provisions of the Plan and make final determinations concerning
the meaning of the Plan and the right of any person to benefits under the
Plan.  

          Each covered employee, or other person claiming through the employee,
must file a written claim for benefits with the Plan Administrator as a 
prerequisite to the payment of benefits under the Plan.  Any denial by the Plan
Administrator of a claim for benefits under the Plan by an employee or other
person (collectively referred to as "claimant") shall be stated in writing by
the Plan Administrator and delivered or mailed to the claimant within 90 days
after receipt of the claim, unless special circumstances require an extension
of time for processing the claim.  If such an extension of time is required,
written notice of the extension shall be furnished to the claimant prior to the
termination of the initial 90-day period.  In no event shall such extension
exceed a period of 90 days from the end of the initial period.  

          Any notice of denial shall set forth the specific reasons for the
denial, specific reference to pertinent 


                                     -9-
<PAGE>   10


provisions of the Plan upon which the denial is based, a description
of any additional material or information necessary for the claimant to perfect
his claim, with an explanation of why such material or information is
necessary, and any explanation of claim review procedures under the Plan,
written to the best of the Plan Administrator's ability in a manner that may be
understood without legal or actuarial counsel.  

          A claimant whose claim for benefits has been wholly or
partially denied by the Plan Administrator may request, within 90 days
following the date of such denial, in a writing addressed to the Plan
Administrator, a review of such denial.  The claimant shall be entitled to
submit such issues or comments in writing or otherwise, as he shall consider
relevant to a determination of his claim, and may include a request for a
hearing in person before the Plan Administrator.  Prior to submitting his
request, the claimant shall be entitled to review such documents as the Plan
Administrator shall agree are pertinent to his claim.  The claimant may, at all
stages of review, be represented by counsel, legal or otherwise, of his choice,
provided that the fees and expenses of such counsel shall be borne by the
claimant.  

          All requests for review shall be promptly resolved.  The Plan
Administrator's decision with respect to any such review shall be set forth in  
writing and shall be mailed to the claimant not later than 60 days following
receipt by the Plan Administrator of the claimant's request unless special
circumstances, such as the need to hold a hearing, require an extension of time
for processing, in which case the Plan Administrator's decision shall be so
mailed not later than 120 days after receipt of such request.

          5.3   Arbitration.  Exhaustion of the claim and claim review 
procedures of Section 5.2 is prerequisite to any further consideration of
a claim.  In the event that any claim remains fully or partially unresolved
after exhaustion of the claim and claim review procedures of Section 5.2, any
remaining dispute shall, within 30 days of the date of the Plan Administrator's
final decision on review, be submitted 


                                    -10-
<PAGE>   11

to arbitration, which shall be the sole and exclusive remedy.  The arbitration
decision shall be final and binding on the Plan, TriMas, the claimant, and any
other party involved.  All claims shall be arbitrated in Taylor, Michigan.  The
arbitrator shall be chosen in accordance with the Voluntary Labor Arbitration
Rules of the American Arbitration Association then in effect, and the expense   
of the arbitration shall be shared equally by TriMas and the claimant.  Any
claim shall be deemed waived unless presented within the time limits specified
in Section 5.2 and this Section 5.3.  The arbitrator shall not have
jurisdiction or authority to change, add to or subtract from any of the
provisions of the Plan.  The arbitrator's sole authority shall be to interpret
or apply the provisions of the Plan.  Because arbitration is the exclusive
remedy with respect to any claim hereunder, neither TriMas, the claimant nor
any other party has the right to resort to any federal, state or local court or
administrative agency concerning any claim, and the decision of the arbitrator
shall be a complete defense to any suit, action or proceeding instituted in any
federal, state or local court or before any administrative agency with respect
to any dispute which is arbitrable as herein set forth.  The arbitration
provisions hereof shall, with respect to any claim, survive the termination of
the Plan.

                                  SECTION 6
                   LIMITATION OF COVERED EMPLOYEE'S RIGHTS



          6.1   No Contract of Employment.  The Plan shall not be deemed to
create a contract of employment between TriMas or any TriMas subsidiary and any 
covered employee and shall create no right in any covered employee to continue
in the employ of TriMas or any of its subsidiaries for any specific period of
time, or to create any other rights in any covered employee or obligations on
the part of TriMas, except as are set forth explicitly herein or in a written
employment contract.  In consideration of his coverage hereunder each covered
employee shall be deemed to have agreed that TriMas has the right to terminate
him at any time, with or without cause, and nothing in the Plan shall restrict
the right of any covered employee to terminate his employment.

          6.2   Unsecured Creditor.  The rights of any employee or any person
claiming through the employee under the Plan shall be solely those of an
unsecured general creditor of TriMas.  Any employee, or any person
claiming through the employee, shall only have the right to receive from TriMas
those payments as specified herein.  Each covered employee agrees that he or
any person claiming through him shall have no rights or interests in any asset
of TriMas, including any insurance policies or contracts which TriMas may
possess to informally fund the Plan.

          6.3   No Trust.  No asset used or acquired by TriMas in connection 
with the liabilities it has assumed under the Plan shall be deemed to be held
under any trust for the benefit of any employee nor shall any such asset
be considered security for the performance of the obligations of TriMas, but
shall be, and remain, a general unpledged and unrestricted asset of TriMas,
except as may be provided by separate agreement and as permitted under Internal
Revenue Service and Department of Labor rules and regulations for 


                                    -12-

                             AMENDMENT OR TERMINATION



          7.1   Right to Amend or Terminate Plan.  TriMas reserves the right to
amend the Plan in any manner deemed appropriate by TriMas's Board of Directors, 
and TriMas reserves the right to terminate the Plan for any reason and at any
time in whole or part by action of the Board of Directors.

          7.2   Limitations.  Notwithstanding Section 7.1, no such amendment or
termination shall reduce or otherwise affect the benefits payable to or on
behalf of any covered employee that have accrued prior to such amendment or
termination without the written consent of the employee (or beneficiary, if
applicable).  In addition, the complete or partial termination of this Plan,
should it occur or be deemed by facts and circumstances to have occurred, shall
have the same effect on the vesting of benefits accrued to date under this Plan
as in the case of a complete or partial termination of a Qualified Plan.

          7.3  Payment of Benefits Upon Termination.  Upon termination or 
partial termination of the Plan TriMas may elect the method by which benefits
accrued through the date of such termination or partial termination shall be
provided.  Such election may include the payment of the present value of all
such accrued benefits directly to covered employees (or beneficiaries, if
applicable) or any other method of payment or funding which TriMas may, in its
sole discretion, determine.

                             MISCELLANEOUS PROVISIONS



          8.1   Independence of Benefits.  Except as otherwise provided herein
or pursuant to the terms of any separate agreement with an employee, the
benefits payable under the Plan shall be independent of, and in addition
to, any other benefits or compensation, whether by salary, or bonus or
otherwise, payable under any employment agreements that now exist or may
hereafter exist from time to time between TriMas and any employee.  The Plan
does not involve a reduction in salary or foregoing of an increase in future
salary by any employee, nor does the Plan in any way affect or reduce the
existing and future compensation and other benefits of any employee.

          8.2   Nonalienation of Benefits.  Except insofar as this provision may
be contrary to applicable law (such as an order of divorce or separation), no
sale, transfer, alienation, assignment, pledge, collateralization, or attachment
of any benefits under the Plan shall be valid or recognized by TriMas.

          8.3   Payments for the Benefit of Employee.  In the event that TriMas
shall find that any person to whom a benefit is payable under the Plan is
unable  to care for his affairs because of illness or accident, is otherwise
mentally or physically incompetent, or is unable to give a valid receipt,
TriMas may cause the payments becoming due to such person to be paid to another
individual for such person's benefit, without responsibility on the part of
TriMas to follow application of such payment.  Any such payment shall be a
payment on account of such person and shall operate as a complete discharge of
TriMas from all liability under the Plan.

          8.4   Use of Words.  Wherever any words are used in 



                                    -15-

<PAGE>   16

the Plan in the masculine gender, they shall be construed as though they also
were used in the feminine gender in all cases where they would so apply,
and wherever any words are used in the Plan in the singular forms they shall be
construed as though they also were used in the plural form in all cases where
they would so apply, and vice versa.

          8.5   Headings.  Headings of Sections herein are inserted for
convenience of reference.  They constitute no part of the Plan and are not to be
considered in the construction of the Plan.

          8.6   Savings Clause.  If any provisions of the Plan shall be for any
reason invalid or unenforceable, the remaining provisions nevertheless shall be
carried into effect.

herein shall be construed in reference to the same or similar terms as used in

      This Agreement (the "Agreement") is made as of the 10th day of December,

      The Company believes that executing this Agreement is in the best interest
of the Company and its shareholders and the Employee believes that the execution
of this Agreement is in his best interests; and 

      The Company and the Employee desire to enter into this Agreement; 

      NOW, THEREFORE, to induce the Employee to remain in the employ of the
Company, and for other good and valuable consideration, the Company and the
Employee agree as follows:

      1.    Definitions.

            (i)    "Benefit Period" shall mean the period commencing on the date

      the date hereof;

                    (c)   a reduction in the Employee's base salary as in effect
      on the date of this Agreement or as the same may be increased from time

      consistent with the Employee's current business travel obligations on the
      date of this Agreement; or 

                    (e)   the failure by the Company to comply with any of its
      obligations under Section 13(i).

            (x)     "Minimum Bonus Compensation" shall apply  to the years ended
December 31, 1997 and December 31, 1998 only and shall mean the bonus amount of
$285,000.

            (xi)    "Protected Vesting Period" shall have the meaning set forth
in Section 9(vii) of this Agreement. 

            (xii)   "Termination Date" shall mean the effective date as provided

(Restated December 5, 1995) representing awards, options or grants granted prior
to February 28, 1998.

            (xiv)   "Without Cause" when used in connection with the
termination of the Employee's employment by the Company, shall mean any
termination of employment of the Employee by the Company which is not a
termination of employment for Cause or Disability.

      2.    Employment, Acceptance and Term.  The Company hereby employs the
Employee in a senior management position with the Company and the Employee
hereby accepts such employment with the Company on the terms set forth in this
Agreement for the Contract Employment Period unless sooner terminated pursuant
to the provisions of Sections 7 or 8 of this Agreement or upon the Employee's
death (the "Employment Term").

      3.    Duties and Authority.  During the Employment Term, the Employee
shall devote his full business time and energies to the business and affairs of
the Company and shall not, without the Company's written consent,  accept
other employment or permit such personal business interests as he may have to
interfere with the performance of his duties under this Agreement.  The
Employee agrees to use his best efforts, skill and abilities to promote the
interests of the Company, to work with other employees of the Company in a
competent and professional manner and generally to promote the interests
of the Company and to perform such other duties of a management or professional
nature as may be assigned to him by the Chairman or Board of the Company.  

      4.    Compensation. For all services to be performed by the Employee
during the Employment Term the Company shall pay the Employee an annual base
salary of not less than Five Hundred Twenty Eight Thousand ($528,000) Dollars
per year, payable in accordance with 

                                     -5-
<PAGE>   6

the prevailing payroll practices of the Company and less all applicable taxes
required to be withheld by federal, state or local laws.  The Employee shall be
eligible for annual merit increases in base salary, consistent with the annual
merit increases granted to other comparably compensated employees of the
Company.  In addition during the Employment Term, the Employee shall be
entitled to such bonus pursuant to the Company's bonus plan, in effect on the
date hereof or which may hereafter exist, to the extent the Employee meets the
eligibility requirements of such plan and such other discretionary compensation
as in each case may be  awarded from time to time in the discretion of the
Board, provided that, during the Employment Term, the Company shall pay to the
Employee as a bonus (a) for 1997 and 1998 an amount not less than the Minimum
Bonus Compensation, and (b) for 1999 and 2000 an amount commensurate with other
comparably compensated employees of the Company but not less than ninety
percent (90%) of the Employee's 1998 bonus.  

      5.    Participation in Employee Benefit Plans.  In addition to the cash
compensation payable hereunder, the Employee shall be entitled to participate
during the Employment Term in such employee benefit plans, whether contributory
or non-contributory, such as group insurance plans, hospital, surgical, vision
and dental benefit plans or other bonus incentive, profit sharing, retirement
or employee benefit plans of the Company existing on the date hereof or as may
be subsequently amended or adopted by the Company for management employees in   
significant or responsible management positions covered thereby to the extent
that the Employee meets the general eligibility requirements of any such plans. 
These plans include, without limitation, the TriMas Corporation Pension Plan,
the TriMas Corporation Future Service Profit Sharing Plan, the TriMas
Corporation Salaried Savings Plan, the TriMas Corporation Retirement Benefit 


                                     -6-
<PAGE>   7

Restoration Plan and the TriMas Corporation Supplemental Executive Retirement
and Disability Plan.  The Employee shall be entitled during each year of the
Employment Term to paid vacation time consistent with past practice and Company 
policy for comparable senior executives.  Any reference to a benefit plan under
this Agreement, including without limitation those referenced in this Section 5
and in Section 1(xiii), shall include any successor plans (the "Plans"). 

      6.    Application of this Agreement: Term of Agreement.  The provisions of
Sections 7 and 8 of this Agreement shall apply with respect to any termination
of employment of the Employee which occurs during the period commencing on the
date of this Agreement and ending on March 8, 2003.  Such provisions shall not
apply to any termination of employment of the Employee which occurs following
March 8, 2003 after which date the Employee shall have no further rights
under this Agreement except to the extent they have heretofore accrued to the
Employee, including without limitation those which have accrued under Section
9.  Continuation of employment with a successor to TriMas Corporation, as
described in Section 13(i), shall not alone constitute termination of the
Employee's employment.  

      7.    Termination of Employment of the Employee By the Company.

            (i)     The Company shall have the right to terminate the Employee's
employment hereunder at any time for Disability, for Cause, or Without Cause in
each circumstance; however if such termination occurs during the Contract
Employment Period, the Company will be required to comply with the procedures
hereinafter specified. 

            (ii)    During the Contract Employment Period, termination of the
Employee's employment for Disability shall become effective no sooner than
thirty (30) days after a notice of intent to terminate the Employee's
employment, specifying Disability as the basis for such 

                                     -7-

termination, is given to the Employee by the Board, by a committee of the Board
or by the officer to whom the Employee normally reports and any applicable
requirements of the Company'S long term disability plan or, if the Company has
no such plan, its administrative practices then applicable to disability have
been met.  

            (iii)   During the Contract Employment Period, termination of the
Employee's employment for Cause shall be effective immediately upon written
notification from the Board, a committee of the Board, or the officer to whom
the Employee normally reports, to the Employee stating in such notice that the
Employee is terminated for Cause and providing reasonable detail of the facts
and circumstances claimed by the Company to constitute Cause.  In the event the
Employee believes that there was not Cause for such termination, the Employee
may notify the Company in writing of such belief within fifteen (15) days after
the Company's delivery of written notice of termination for Cause to the
Employee.  In the event the Employee gives notice to the Company within such
fifteen (15) day period, the Employee shall (unless such an opportunity has
been previously offered to the Employee) within fifteen (15) days of the giving
of such notice be afforded an opportunity, together with the Employee's
counsel, to be heard before the superior to the officer to whom the Employee
normally reports.  If, pursuant to such hearing, such superior officer
determines that there was no Cause for such termination, then such termination
shall be deemed to be Without Cause.  Any determination by such superior
officer shall be in addition to and shall not limit the right of the Employee
to arbitrate whether such termination was for Cause under Section 16 hereof.

            (iv)    The Company shall have the absolute right to terminate the
Employee's employment Without Cause by notice from the President of the Company
or the Board; however, 

                                     -8-
<PAGE>   9

during the Contract Employment Period, termination of the Employee's employment
Without Cause shall be effective on the date specified in the notice but no
sooner than five (5) business days after the date of the Company's giving to
the Employee a notice of termination, specifying that such termination is
Without Cause.

            (v)    Upon a termination of the Employee's employment for Cause or
(except as provided to the contrary in Section 14) for Disability, the Employee
shall have no right to receive any compensation or benefits based on the
provisions of this Agreement provided, however, with respect to Disability
nothing in this sentence shall restrict any benefits that the Employee would
otherwise receive upon the occurrence of the Employee's disability under any
benefit plans of the Company covering the Employee.  Upon a termination of the
Employee's employment Without Cause, the Employee shall be entitled to receive
the benefits provided in Section 9 hereof.

      8.   Termination of Employment By the Employee.  The Employee shall be
entitled at any time to terminate employment with the Company for any reason
and, if such termination is for Good Reason, to receive the benefits provided
in Section 9 hereof in the same manner as if such Employee had been terminated  
Without Cause.  The Employee shall give the Company notice of voluntary
termination of employment, which notice need specify only the Employee's desire
to terminate employment and, if such termination is for Good Reason, also set
forth in reasonable detail the facts and circumstances claimed by the Employee
to constitute Good Reason.  Any notice by the Employee pursuant to this Section
shall be effective five (5) business days after the date it is given by the
Employee.  If the Employee terminates his employment with the Company other
than for Good Reason, the Employee shall not be entitled to receive benefits
under this Agreement except those provided in Section 9(i) and 9(ii) hereof.

      9.    Benefits Upon Termination in Certain Circumstances.  Upon the
termination of the Employee's employment by the Company Without Cause pursuant
to Section 7(iv) hereof or by the Employee for Good Reason pursuant to Section
8 hereof during the period commencing on the date of this Agreement and ending
on March 8, 2003, the Employee shall execute a Separation Agreement and
Complete Release of Liability in the form attached as Exhibit A hereto (the
"Release") in favor of the Company and commencing eight (8) days thereafter,
provided the Employee did not revoke the Release pursuant to Section 8 thereof,
the Employee shall be entitled to receive the following benefits:

            (i)     The Company shall pay to the Employee, not later than thirty
(30) days after the Termination Date, a lump sum cash amount equal to the sum
of (a) the full base salary earned by the Employee through the Termination Date
and unpaid at the Termination Date, (b) the amount of any base salary
attributable to vacation earned by the Employee but not taken before the
Termination Date, (c) all other amounts earned by the Employee and unpaid
at the Termination Date (including any amount of a bonus remaining unpaid from
a prior performance year), and (d) all amounts owing by the Company on account
of expenditures by the Employee on behalf of the Company, including without
limitation all amounts due as reimbursement of travel and entertainment
expenses.

            (ii)    The Company shall pay to the Employee, not later than thirty
(30) days after the Termination Date, the greater of  (a) a pro-rata amount of
any bonus award earned by the Employee during the year in which the Termination
Date occurred; or (b) a pro-rata amount (x) in cases in which the Termination
Date occurs during 1997 and 1998, of the Minimum Bonus Compensation, and (y) in
cases in which the Termination Date occurs after December 31, 1998, of 

                                    -10-
<PAGE>   11

the Employee's cash bonus incentive compensation for the immediately preceding
full year prior to the Termination Date.  In each case, the proration shall be
based on the number of days in the year through the Termination Date compared
with 365 days.

            (iii)   The Company shall pay to the Employee a cash amount equal
to, the Employee's Base Annual Compensation multiplied by a fraction, 

            (A)  the numerator of which is (x) if the Termination Date occurs
                 before March 8, 2000, the number of days remaining in the
                 Contract Employment Period or, (y) if the Termination Date
                 occurs on or after March 8, 2000, the number 365 and 

            (B)  the denominator of which is 365 (the "Termination Payment"). 
"Base Annual Compensation" shall be the sum of (a) the Employee's base annual
salary at the highest rate in effect during the year of the Termination Date
plus (b) the greater of (x) the Employee's cash incentive bonus compensation
for the full year immediately preceding the Termination Date or (y) in cases in
which the Termination Date occurs during 1997 or 1998, the Minimum Bonus
Compensation, and (z) in cases in which the Termination Date occurs during the
period from January 1, 1999 through March 8, 2003, an amount equal to the
Employee's cash bonus incentive compensation pursuant to Section 4 hereof for
the immediately preceding full year prior to the Termination Date.  The
Termination Payment shall be paid at the option of the Employer either (a) in
equal monthly installments over the remaining months of the Benefit Period, or
(b) (x) in a lump sum equal to the lesser of the Termination Payment or the
Employee's Base Annual Compensation, payable within thirty (30) days of the
Termination Date, and (y) the amount, if any, by which the Termination Payment
exceeds such lump sum payment made, in equal


                                    -11-
<PAGE>   12

monthly installments commencing one (1) year after the Termination Date and
ending in the last month of the Benefit Period.  

            (iv)    The Company shall also pay to the Employee all legal fees
and expenses incurred by the Employee as a result of successfully enforcing any
right or benefit provided to the Employee by this Agreement.

            (v)     The Company shall pay, when due, for outplacement services
as requested by the Employee to assist in locating new employment, up to a
maximum amount of $30,000.  

            (vi)    The Company shall maintain in full force and effect for the
Employee's continued benefit, and for the benefit of the Employee's dependents,
until the earlier of (a) the end of the Benefit Period or (b) the Employee's
commencement of employment with a new employer, any medical or dental insurance
plans or medical or dental insurance arrangements in which the Employee was
entitled to participate upon the Termination Date (subject to the Company's
right under Section 5 of this Agreement to amend or replace such plans or
arrangements after the Termination Date), provided that the Employee's
continued participation is possible under the general terms and provisions of
such plans or arrangements.  In the event that the Employee's participation in
any plans or arrangements of a new employer is barred, then until the end of
the Benefit Period, the Company shall arrange to provide the Employee with
benefits substantially similar to those which the Employee is entitled to
receive under such plans or arrangements of the Company.  Should the medical
insurance plans or arrangements provided by the Employee's new employer not
entitle the Employee or the Employee's dependents (a) to any coverage during an
initial qualification period or (b) to coverage for any condition which is
considered a pre-existing condition under the new employer's plan and which was
covered under the Company's medical 

                                    -12-
<PAGE>   13

insurance plans or arrangements at the Termination Date, then notwithstanding
the Employee's employment, the Company shall, until the end of the Benefit
Period, continue to provide medical benefits as stated above in this Section
9(vi) during such qualification period (if clause (a) of this sentence is
applicable) and for such pre-existing condition (if clause (b) of this sentence
is applicable).  

            (vii)   Any Unvested Options of the Employee under the Company's
Plans shall, to the extent such Unvested Options have not been converted or
adjusted in any transaction approved by the Company's Board of Directors as
contemplated by the applicable Plan, immediately vest at the Termination Date. 
All Unvested Stock Awards under the Company's Plans shall continue to vest in
accordance with the terms of the respective Plans during the period which (x)
if the Termination Date occurs before March 8, 2000, shall extend until June
30, 2001, or (y) if the Termination Date occurs on or after March 8, 2000,
shall extend until the last day of the end of the fifteen (15th) month
following the Termination Date, (the applicable time period of this sentence is
referred to as the "Protected Vesting Period").  All Unvested Stock Awards, as
to which restrictions have not lapsed under the Plan as provided in the
preceding sentence, shall be forfeited to the Company.

            (viii)  The Employee's right to participate in the Company's non-
qualified Supplemental Executive Retirement and Disability Plan ("SERP"), shall
terminate on the Termination Date unless the Employee hereafter becomes entitled
to vested benefits thereunder as a result of future amendments to SERP
agreements generally implemented for Company's management employees with
significant or responsible management positions covered thereby. 

      Any payments to be made under this Section 9 (except payments under
subsection (vi)) 

                                    -13-
<PAGE>   14

shall be reduced by the amount of (a) any loans or other monetary advances made
by the Company to the Employee which remain outstanding on the Termination
Date are to be paid back to the Company according to the terms of the current
arrangement, (b) any payments made to the Employee pursuant to the SERP, and
(c) any other retirement benefits received by the Employee from the Company. 
      
      Subject to the succeeding paragraph, in the event that any payments,
distributions or benefits to or for the benefit of the Employee from the
Company, whether paid or payable, distributed or distributable, as provided for
in Section 9 hereof, any other section of this Agreement, or otherwise under
any other plan or arrangement of the Company would constitute a "parachute
payment", as defined in Section 280G of the Internal Revenue Code of 1986, as
amended, or any successors thereto (the "Code"), such payments under the
Agreement shall be reduced to the largest amount that will eliminate both the
imposition of the excise tax imposed by Section 4999 of the Code and the
disallowance as deductions to the Company under Section 280G of the Code of any
such payments under this Agreement.  The determination of any reduction in the
payments under this Agreement pursuant to this paragraph shall be made by a
major accounting firm selected by the Company (which shall not be the Company's
independent auditors) and approved by the Employee, which approval shall not be
unreasonably withheld.

      Upon the termination of the Employee's employment by the Company Without
Cause or by the Employee for Good Reason, in each case prior to March 31, 1999,
then in the event that any payments, distributions or benefits to or for the
benefit of the Employee from the Company, whether paid or payable, distributed
or distributable, as provided for in Section 9 hereof, any other section of this
Agreement, or otherwise from the Company would be subject to an excise 

                                    -14-
<PAGE>   15

tax pursuant to Section 4999 of the Code, or subject to any interest or
penalties with respect to such excise tax, the Employee shall be entitled to
receive, not later than three (3) days prior to the date upon which the
Employee is required to make any payment based on such determination,
additional payments from the Company in an amount equal to all additional
income and excise taxes (including interest and penalties thereon) payable,
including income and excise taxes, interest and penalties, on any payment
received pursuant to this sentence, by the Employee by reason of the imposition
of such excise tax pursuant to Section 4999 of the Code.  All taxes deemed
payable hereunder are to be calculated by a major accounting firm selected by
the Company (which shall not be the Company's independent auditors) and
approved by the Employee, which approval shall not be unreasonably withheld,
using maximum marginal rates applicable to the Employee.  If, after the payment
of any amount pursuant to this paragraph, the Company elects to contest such
tax or taxes, the Employee shall cooperate with the Company, in good faith at
the Company's sole expense, to contest such tax or taxes.  If the Company
is successful in contesting any proposed tax, the Employee shall return to the
Company, upon receipt by the Employee, any refunds (including any interest paid
or penalties remitted on any such refunds) with respect to such contested tax
or taxes and any other payments made by the Company to the Employee pursuant to
this paragraph with respect to the amount refunded.

      10.   Other Employment; Mitigation. The Employee shall not be required to
mitigate the amount of any payment or benefit provided for in Section 9 by
seeking other employment.  The amount of any payment or benefit provided for in
Section 9 shall not be reduced by any compensation earned by the Employee as
the result of other employment or consulting services performed. 

                                    -15-
<PAGE>   16

      11.   Life and Disability Insurance.  During the Benefit Period, the
Company will continue to maintain in effect and pay the premiums on any
insurance policies insuring the life or disability of the Employee which are in
effect on the effective date hereof or may hereafter be taken out by Company,
or substitute policies for all significant management employees covered
thereby.

      12.   Non-Competition.  In consideration of the payments to be received by
the Employee hereunder, in recognition of the highly competitive nature of the
industries in which the Company conducts its business and to further protect the
goodwill of the Company and to promote and preserve its legitimate business
interests, the Employee agrees that during the period commencing the date hereof
and ending on the last day of the Protected Vesting Period, he will not:

            (i)     Engage in any Business Activities (other than on behalf of
the Company) whether such engagement is as an officer, director, proprietor,
employee, partner, investor (other than as a holder of less than 1% of the
outstanding capital stock of a publicly traded corporation), consultant
advisor, agent or otherwise, in any geographic area in which the products or
services of the Company have been distributed or provided during the period
commencing two years prior to the date hereof and ending on the Termination
Date;

            (ii)    Other than on behalf of the Company supply products or
provide services (but only to the extent such restricted activities constitute
Business Activities) to any customer with whom the Company has done any
business during the period commencing two years prior to the date hereof and
ending on the Termination Date, whether as an officer, director,
proprietor, employee, partner, investor (other than as a holder of less than 1%
of the outstanding capital stock of a publicly traded corporation), consultant,
advisor, agent or otherwise;

                                    -16-
<PAGE>   17
            (iii)   Assist others in engaging in any of the Business Activities
in the manner prohibited to the Employee; and

            (iv)    Induce or attempt to induce employees of the Company, or its
affiliates to engage in any activities hereby prohibited to the Employee or to
terminate their employment. It is expressly understood and agreed that although
the Employee and the Company consider the restrictions contained in each of     
clauses (i) through (iv) above to be reasonable for the purpose of preserving
the Company's goodwill, proprietary rights, trade secrets, valuable
confidential business interests, relationships with specific prospective and
existing customers and going concern value, and to protect the Company's
business opportunities, markets and trade areas, if a final judicial
determination is made by a court having jurisdiction that the time or territory
or scope of restricted activities or any other restriction contained in this
Agreement is an unenforceable restriction on the activities of the Employee,
the provisions of this Agreement shall not be rendered void but shall be deemed
amended to apply as to such maximum time, restricted activities and territory
and to such other extent as such court may judicially determine or indicate to
be reasonable.  Alternatively, if the court referred to above finds that any
restriction contained in this Section 12 is unenforceable, and such restriction
cannot be amended so as to make it enforceable, such finding shall not affect
the enforceability of any of the other restrictions contained therein.  It is
further expressly understood and agreed that the providing of Professional
Services shall not be restricted under this Agreement.

      13.   Successors: Binding Agreement.

            (i)     The Company shall require any successor (whether by
purchase of all or substantially all of the business and/or assets, merger,
consolidation or liquidation) of the Company 

                                    -17-
<PAGE>   18

to expressly assume, by written agreement, the obligation of the Company to
perform this Agreement upon or prior to such succession taking place.  A copy of
such written agreement shall be delivered to the Employee promptly after its
execution by the successor or such person or group. 

            (ii)    Failure of the Company to obtain such agreement upon or
prior to the effectiveness of any such succession shall be a breach of this
Agreement and shall entitle the Employee to benefits as set forth above in
Section 9.  These amounts shall not be discounted to any present value.  

            (iii)   This Agreement is personal to the Employee and the Employee
may not assign or transfer any part of the Employee's rights or duties
hereunder, or any compensation due to the Employee hereunder, to any other
person, except that this Agreement shall inure to the benefit of and be
enforceable by the Employee's personal or legal representatives, executors,
administrators, heirs, distributees, devisees, legatees or beneficiaries.

      14.   Death: Disability.  If the Employee dies or experiences a Disability
on or prior to March 8, 2003 and before the date that the Employee gives notice
of termination for Good Reason pursuant to Section 8 hereof, or before the
Company gives notice of termination Without Cause pursuant to Section 7(iv)
hereof, or for Cause pursuant to Section 7(iii) hereof, the Employee shall not
be entitled to any benefits under this Agreement provided, however, such
restriction shall not otherwise restrict any benefits that the Employee would
otherwise receive upon the occurrence of the Employee's death or disability
under any benefit plans of the Company covering the Employee. If the Employee
dies or experiences a Disability on or prior to March 8, 2003 and on or after
the date that the Employee gives notice of termination for Good Reason pursuant
to Section 8 hereof, or on or after the Company gives notice of termination
Without Cause pursuant to Section 7(iv)

                                       -18-
<PAGE>   19

hereof, the Employee shall be entitled to the benefits available to the
Employee under this Agreement and any such benefits shall not be reduced in any
way because of such death or Disability.  If the Employee dies on the date the
Employee is terminated for Cause the Employee shall not be entitled to any
benefits hereunder unless it is subsequently determined pursuant to this
Agreement that such termination was not for Cause.  

      15.   Modification: Waiver.  No provisions of this Agreement may be
modified, waived or discharged unless such waiver, modification or discharge is
agreed to in a writing signed by the Employee and by the Company, provided,
however, the Employee shall not be required to execute as a condition of
continued employment any additional agreement or any agreement which modifies
or replaces this Agreement during the Benefit Period.  Waiver by any party of
any breach of or failure to comply with any provision of this Agreement by the
other party shall not be construed as, or constitute, a continuing waiver
of such provision, or a waiver of any other breach of, or failure to comply
with, any other provision of this Agreement.

      16.   Arbitration of Disputes.

            (i)     Except with respect to the enforcement of the Company's
rights under Section 12 hereof or the enforcement of the Company's rights under
the Release, any disagreement dispute, controversy or claim arising out of or
relating to this Agreement, the interpretation or validity hereof, or the terms
and conditions of Employee's employment including the termination thereof,
shall be settled exclusively and finally by arbitration.  Except as provided in
the preceding sentence, it is specifically understood and agreed that any
disagreement dispute or controversy which cannot be resolved between the
parties, including without limitation any matter relating to the interpretation
of this Agreement, claims of discrimination under state or federal law, shall
be 

                                    -19-
<PAGE>   20

resolved solely by arbitration irrespective of the magnitude thereof, the amount
in controversy, or the nature of the relief sought.

            (ii)    The arbitration shall be conducted in accordance with
Employment Arbitration Rules (the "Arbitration Rules") of the American
Arbitration Association (the "AAA"), the terms of which are incorporated herein.

            (iii)   The arbitral tribunal shall consist of one arbitrator
skilled in arbitration of senior executive employment matters.  The parties to
the arbitration shall jointly directly appoint such arbitrator within thirty
(30) days of initiation of the arbitration.  If the parties shall fail to
appoint such arbitrator as provided above, such arbitrator shall be
appointed by the AAA as provided in the Arbitration Rules and shall be a person
who has had substantial experience in senior executive employment matters.  The
Company shall pay all of the fees, if any, and expenses of such arbitrator and
the arbitration.

            (iv)    The arbitration shall be conducted in the Southeastern
Michigan area or in such other city in the United States of America as the
parties to the dispute may designate by mutual written consent.

            (v)     At any oral hearing of evidence in connection with the
arbitration, each party thereto or its legal counsel shall have the right to
examine its witnesses and to cross-examine the witnesses of any opposing party. 
No evidence of any witness shall be presented in form unless the opposing party
or parties shall have the opportunity to cross-examine such witness, except as
the parties to the dispute otherwise agree in writing or except under
extraordinary circumstances where the interests of justice require a different
procedure.

                                    -20-
<PAGE>   21

            (vi)    Any decision or award of the arbitral tribunal shall be
final and binding upon the parties to the arbitration proceeding.  The parties
hereto agree that the arbitral award may be enforced against the parties to the 
arbitration proceeding or their assets wherever they may be found and that a
judgment upon the arbitral award may be entered in any court having
jurisdiction.

            (vii)   Nothing herein contained shall be deemed to give the
arbitral tribunal any authority, power, or right to alter, change, amend,
modify, add to, or subtract from any of the provisions of this Agreement.

      17.   Notice.  All notices, requests, demands and other communications
required or permitted to be given by either party to the other party by this
Agreement (including, without limitation, any notice of termination of
employment and any notice under the Arbitration Rules of an intention to
arbitrate) shall be in writing and shall be deemed to have been duly given when

      23.   Entire Agreement.  This Agreement supersedes any and all other oral
or written employment agreements heretofore made and constitutes the entire
agreement of the parties relating to the subject matter hereof. 
Notwithstanding the forgoing, this Agreement is not intended to and does not
alter or amend any agreements between the Employee and the Company relating to
matters such as non-competition and non-disclosure of Company matters, and is
not intended to and does not limit the Employee's obligations under any
Company employee benefit or welfare plan or limit, restrict, or reduce any
employee benefit that the Employee is entitled to under any other agreement,
plan, or arrangement, including without limitation as applicable, those
providing for stock options, restricted stock, disability insurance or life
insurance.  

      24.   Additional Benefits.  During the Employment Term, the Company shall
provide the Employee with reasonable and suitable office space in Ann Arbor,
Michigan and a secretary located in Ann Arbor, Michigan at such office for as
long as the Employee is providing ongoing services hereunder to the Company. 
The Employee shall be responsible for selecting his secretary and the Company

subsidiaries and affiliates and their respective officers, directors and
employees, or (iv) without Company's prior written consent, induces any

reimburse the Company for all such damage or injury occasioned by such action,

                  DESCRIPTION OF THE MASCOTECH, INC. 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
established 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.

                                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 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
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 Company'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.

                                  OF MASCO

its incorporation, has full power and authority to own its properties and to

forth in Schedule I hereto.  The outstanding shares of capital stock of each of
the Companies (collectively the "Shares") are owned of record and beneficially

all liens, encumbrances and claims.  All outstanding shares of capital stock of
Masco Indiana are owned of record and beneficially by Masco, free and clear of

series of related transactions are set forth on Exhibit 1.04(c).

        1.05  All corporate action of each of the Companies and the Subsidiary

1.07, the 

                                        -4-


<PAGE>   5

business affairs of the respective Groups have since such date been
conducted in the same manner as theretofore conducted and in the usual and
ordinary course; after the close of business on such date no transaction has
taken place and no material contract has been entered into in respect of any of
the Groups other than in the usual and ordinary course of business; and
specifically, without limitation of the foregoing, there have been no sales,
removals or deliveries of inventory reflected in the December Balance Sheets
(other than shipments of inventory in the usual and ordinary course of business
consistent with past practice), machinery, fixtures or other tangible or
intangible assets of any nature material to the conduct of the business of any
of the Groups, respectively, since that date.

        1.08  Since December 31, 1989 there has been no casualty, loss, damage

has:

            (i) merged or consolidated with another corporation;

            (ii) created, incurred or assumed or committed to create, incur or
      assume indebtedness of other liability, except for (A) intercorporate
      borrowings in the ordinary course of business, and (B) accounts payable
      or other current liabilities which (1) are not for borrowed money and (2)
      were incurred in the usual and ordinary course of business;

      agreement between Local 918 of the International Brotherhood of Teamsters
      and Compac, a copy of which is included in Exhibit 1.15;

            (v) varied insurance coverage;


                                        -5-
<PAGE>   6

            (vi) altered or amended its respective charter documents or by-laws;
      or

            (vii) entered into or materially amended or terminated any contract,
      agreement, franchise, permit or license that is material to the
      operation of any of the Groups, except in the ordinary course of business

      Brotherhood of Teamsters and Compac.

        1.10  Exhibit 1.10 contains lists of substantially all tangible personal
property having a cost in excess of $10,000 owned by the Groups as of
December 31, 1989.

        1.11  Neither this Agreement nor any Exhibits or other documents
furnished to TriMas pursuant hereto which are identified as Exhibits contains
any untrue statement of a material fact or omits to state a material fact
necessary to make the factual statements contained herein of therein, in light
of the circumstances under which they were made, not misleading.  Masco does
not have knowledge of any events, transactions or other facts which, either
individually or in the aggregate, might reasonably give rise to circumstances
or conditions which are reasonably likely to have a material adverse effect on
the general affairs, business, prospects, properties, financial position,
results of operations or net equity of any of the Groups.

        1.12  As of the close of business on December 31, 1989, each of the
Groups had a valid leasehold interest in all of its leases of personalty, had
good and unencumbered marketable title to all personalty of any kind or nature
owned by it, and had a valid legal right to use all other personalty used by it
in its business, free and clear of all liens, encumbrances, claims or other
conditions affecting title or use except for (i) liens for nondelinquent ad
valorem taxes, and (ii) such liens and encumbrances as do not materially
detract from or interfere with the present or reasonably foreseeable use of the
properties subject thereto.  Exhibit 1.12 lists all liens on such personalty
which are known to Masco.

        1.13  The buildings and improvements and the machinery and equipment
owned or used by the Fulton Group are, in the aggregate, in adequate repair and
operating condition and adequate to carry on the business of the Fulton Group
as presently conducted.  The 

                                        -6-
<PAGE>   7

buildings and improvements and the machinery and equipment owned or
used by the other Groups are, in the aggregate, in good repair and in good
operating condition and adequate to carry on the business of such other Groups
as presently conducted.

        1.14  Exhibit 1.14(a) lists by legal description all real property
which was owned (which includes property currently being purchased on land
contract) by each of the Groups as of December 31, 1989, and lists by street
address all other real property which was leased or used by the Groups in their
respective businesses of in which any of the Groups had an interest as of that
date.  As of December 31, 1989, each of the Groups had good and marketable fee
simple title to all real property owned by it and a valid leasehold interest in
all real property described on Exhibit 1.14(a) as being leased by it, free and
clear of all easements, restrictions, encroachments, occupancy agreements,
assessments, liens, encumbrances, claims or other matters affecting title, use
or occupancy except for (i) liens for nondelinquent ad valorem taxes, and (ii)
such easements, restrictions, encroachments, occupancy agreements, assessments,
liens, encumbrances, claims or other matters as do not materially detract from
or interfere with the present or reasonably foreseeable use of the properties
subject thereof.  Exhibit 1.14(b) includes copies of current title reports for
all such real property owned by each of the Groups, and such title reports
describe all easements, liens or encumbrances on such real property that are
known to Masco.  As of December 31, 1989, except for matters that, individually
or in the aggregate, do not have a material adverse effect on any Group, the
rights of any such Group under such leasehold estates were not subordinate to,
or defeasible by, any lien on the subject real estate, or any prior lease
thereon, there were no ground subsidences or slides on such properties, and the
properties and improvements thereon were fully accessible by public roads and
were free from strips, gores and enclaves.  Except for buildings and
improvements on properties indicated as being leased, the buildings and
improvements used by each Group are located on property described in Exhibit
1.14(a), and such buildings and improvements do not encroach onto the property
of other persons.  Except as described on Exhibit 1.14(c), prior to the
Effective Date, the properties, the use of such properties and the conduct
therein of the businesses  of each of the Groups had not violated, and based
upon present and foreseeable uses of such properties are not expected to
violate, any law, rule of regulation of any

                                        -7-
<PAGE>   8

governmental authority, including but not limited to, environmental
laws, zoning ordinances and building codes.  Except as set forth on Exhibit
1.14(c), as of December 31, 1989 such properties were served by utilities,
including but not limited to, water, sewage, gas, waste disposal, electricity
and telephone, and Masco is not aware of any inadequacies with respect to such
utilities.  Prior to the Effective Date, except as set forth on Exhibit
1.14(c), each of the Groups had utilized, stored, delivered for disposal,
disposed of and transported all wastes, whether hazardous or not, in full
compliance with all laws, rules, regulations, ordinances or the common law and
so as not to contaminate any of its properties (whether now or previously owned
or leased) or any other property and so as to not give rise to any remediation
or clean-up obligation under any law, rule, regulation, ordinance or the common
law (including provisions of law or regulation scheduled for future
implementation).  Except as set forth on Exhibit 1.14(c), as of December 31,
1989, the real property owned or leased or previously owned or leased by each
of the Groups did not appear on the National Priority List or any state listing
which identifies sites for remedial clean-up or investigatory actions, and
Masco has no knowledge that any such real property was added to any such list
since the Effective Date.  Except as set forth on Exhibit 1.14(c), as of
December 31, 1989, no asbestos, PCB's, ureaformaldehyde or underground storage
tanks were located on the real property owned or leased (or previously owned or
leased) by any Group and, as of December 31, 1989, the real property owned or
leased or previously owned or leased by each of the Groups had not been used to
handle, treat, store or dispose of and had not otherwise been contaminated
(including without limitation, contamination of soils, groundwater and surface
waters located on, in or under such premises) with pollutants or other
substances which contamination may give rise to a remediation or clean-up
obligation of such property or the property of others under any law, rule,
regulation, ordinance or the common law (including provisions of law or
regulation for future implementation).  Except as set forth on Exhibit 1.14(d),
no governmental authority having jurisdiction over such properties has given
notice to any Group of a possible future imposition of assessments affecting
such properties in excess of any amount reserved on the December Balance Sheets
of the Groups or to exercise the power of eminent domain.  The provisions of
this Section 1.14 shall also apply to the real property of, and actions taken
by, each person controlled by any of the Groups during all periods ending prior
to the Effective Date in which such person was 

                                        -8-
<PAGE>   9

controlled by such Group.  The Reese Group has applied for all environmental
permits required for the installation of the powdered paint line currently being
installed by such Group.

        1.15  Except as set forth in Exhibit 1.15, none of the Groups is a
party to or bound by any written agreement, contract or commitment (a) having a
remaining term of more than one year or providing for payments to or by any of
them in excess of $50,000; (b) providing for employment or which contains any
severance or termination pay liabilities or obligations; (c) with any union or
other collective bargaining representative of its employees; or (d) providing
for or evidencing indebtedness for borrowed money.  Exhibit 1.15 also includes
copies of all leases of real property and all pension, stock option, stock
purchase, bonus, profit sharing or other employee or executive welfare or
benefits plans or agreements as to which any of the employees of the Groups
participate, other than copies of multiemployer plans.

        1.16  All of the agreements, contracts and commitments of the Groups
are valid and binding obligations of the parties thereto in accordance with
their respective terms and, prior to the Effective Date, there has occurred no
event which would constitute any breach of or default in any provision of any
such agreement, contract or commitment or which would permit the acceleration
of any obligation of any party thereto or the creation of a lien or encumbrance
upon any asset of any of the Groups or which would give rise to any such
liabilities upon the giving of notice or lapse of time.  As of the date hereof,
Masco is not aware of increased competitive activities or of plans for such
increased activities in any of the markets for any of the Groups' products over
the level of competitive activities experienced by any such Group during the
previous twelve month period.  As of the date hereof, no information has been
brought to the attention of Masco which might reasonably lead Masco to believe
that any customer or supplier of any of the Groups intends to cease dealing
with such Group or intends to alter in any material respect the amount of such
customer's or supplier's dealings with such Group or would alter in any
material respect such dealings, in each case in the event of the consummation
of the transactions contemplated hereby.

        1.17  To the knowledge of Masco and except for transactions with
affiliates of the Groups described on Exhibit 1.04(c), no material portion of
the sales or other ongoing business 

                                        -9-
<PAGE>   10

relationships of any of the Groups is dependent upon the friendship or
the personal relationships (other than those customary within business
generally) of any employees of the Groups or is dependent upon a corporate
relationship presently existing between Masco or any of its affiliates and any
of the Companies, and, prior to the Effective Date, no employee of any of the
Groups had violated the published business policies of any third party with
respect to gifts, services or corporate business practices.  Except as
reflected in the Financial Statements, as of December 31, 1989, none of the
Groups had outstanding loans or other advances directly or indirectly to or
from any officer, director or employee of that Group or Masco, other than
travel advances in the usual and ordinary course of business.  Exhibit 1.17
lists all officers or other key employees of each of the Groups who terminated
employment with the Groups from January 1, 1988 through the date hereof. 
Except as set forth in Exhibit 1.17, as of the date hereof, Masco has no
knowledge that any officer or other key employee of any of the Groups is
considering the termination of employment.  Prior to the Effective Date,
neither the Groups nor any person acting on behalf of any of the Groups had
engaged in any business practice of the nature referred to in the Report of the
Securities and Exchange Commission dated May 12, 1976, on Questionable and
Illegal Corporate Payments & Practices.  During the period covered by the
Financial Statements, none of the Groups had forgiven or canceled, without
receiving full consideration, any indebtedness owing to it by any of its
officers, directors or other employees.

        1.18  The Groups will incur no liabilities by reason of failure to
comply prior to the Effective Date with applicable laws, regulations, orders
and other requirements of governmental authorities, other than liabilities
reflected in the Financial Statements and liabilities for which TriMas and the
Groups will be indemnified under Section 8.01 hereof.  Irrespective of
insurance coverage, and except (i) as set forth on Exhibits 1.14(c) or 1.18,
and (ii) for routine claims for employee benefits:

            (a) None of the Groups was subject to any judicial, governmental or
      administrative order, judgment or decree on December 31, 1989;

            (b) No investigation, governmental or administrative proceeding or
      other litigation of any kind or nature to which any Group was a party was
      pending on December 31, 1989; and 

                                       -10-
<PAGE>   11

            (c) No claim, arising out of facts, circumstances or conditions
      existing prior to the Effective Date, which claim has not ripened into
      litigation or another proceeding, has been made or (to the best knowledge
      of Masco) threatened against any Group, and there are no facts,
      circumstances or conditions existing prior to the Effective Date which
      will give rise to such a claim, litigation or other proceeding.

Except as set forth on Exhibit 1.14(c), the Groups have each obtained
all governmental licenses, permits, approvals, authorizations, exemptions,
classifications and certificates material to the conduct of their respective
businesses prior to the Effective Date or to the ownership of their respective
properties, all of which as of December 31, 1989 were in full force and effect
in all material respects.

        1.19  Except as set forth on Exhibit 1.19, no employees of any of the
Groups are represented by a union or other labor organization and no
representation question exists respecting the employees of any of the Groups. 
All compensation expense of employees of the Groups during the period covered
by the Financial Statements is reflected as an expense in the Financial
Statements, except as set forth on Exhibit 1.04(b).  Prior to the Effective
Date, each of the Groups had complied with all applicable laws affecting
employment and employment practices, terms and conditions of employment and
wages and hours, and had not engaged in any unfair labor practice; except as
set forth on Exhibit 1.19, prior to the Effective Date there have been no
complaints alleging unfair labor practices against any of the Groups filed with
the National Labor Relations Board; from January 1, 1985 through December 31,
1989, there was no grievance or arbitration proceeding against any of the
Groups arising out of or under a collective bargaining agreement and, to the
knowledge of Masco, no basis therefor exists as a result of facts,
circumstances or conditions existing prior to the Effective Date, in each case
other than routine grievances; except for the collective bargaining agreements
included in Exhibit 1.15, no agreement which is binding on any of the Groups
restricts any from relocating or closing any of its operations; and none of the
Groups has experienced any work stoppage or other labor difficulty since
January 1, 1985.  Each of the employee benefit plans of the Groups or
maintained by Masco on behalf of the Groups complies in all respects with the
Internal Revenue Code of 1986, as amended, and the Employee Retirement 

                                    -11-

Income Security Act of 1974, as amended ("ERISA") and the regulations
thereunder and no "Reportable Event" under ERISA or such regulations has
occurred with respect  to any of such plans, and there exists no condition or
set of circumstances which could result in a Reportable Event.  Except as set
forth on Exhibit 1.19 or Exhibit 1.04(b), the value of all actuarial accrued
liabilities are fully funded by the assets of such plans.  All contributions
for periods prior to the Effective Date have been made or accrued for each of
such plans, except as set forth on Exhibit 1.04(b).  Except as set forth on
Exhibit 1.19, since August 1, 1981 none of the Groups has participated in any
"multiemployer plan" as defined in ERISA.  Exhibit 1.19 includes a copy of a
letter from the administrator of each multiemployer pension plan to which any
Company had an obligation to contribute at any time during the period September
25, 1980 through December 31, 1989 setting forth the estimated withdrawal
liability which would be imposed by such plan if the contributing Company were
to withdraw from such plan in a complete withdrawal, as of the most
recently-available information.  Except as disclosed on Exhibit 1.19, no
Company has incurred a withdrawal (either complete or partial) (as defined in
Section 4203 or 4205 of ERISA) from any multiemployer plan.  There is no
pending dispute between any Company and any multiemployer plan concerning
payment of contributions or payment of withdrawal liability payments.  None of
the Groups will incur liability under ERISA on account of the termination of
any employee welfare or benefit plan since January 1, 1980.  Except as set
forth on Exhibit 1.19, the terminations of all such employee welfare and
pension benefit plans have been approved by the Internal Revenue Service
(except in cases where such approvals are not generally permitted or provided
for) and, in the case of any defined benefit pension plan, by the Pension
Benefit Guaranty Corporation.

        1.20  All inventories (including raw materials, work in process and
finished goods) of the Groups, net of the aggregate reserves deducted
therefrom, reflected on the December Balance Sheets, are in good condition, not
obsolete, nondefective and useable or saleable, in the aggregate at existing
operating profit margins, within one year from the date hereof in the usual and
ordinary course of business as conducted as of the date hereof.  All of the
receivables (other than intercorporate loans) of the Companies and the
Subsidiary of any nature, net of the aggregate reserves deducted therefrom on
the December Balance Sheets, will be collected in the usual and ordinary course
of business without 

                                       -12-
<PAGE>   13

resort to legal proceedings and will be paid in cash within 210 days of the date
of Closing.

        1.21  As of December 31, 1989 all tangible personal property owned by
or an interest in which is claimed by any other person (whether a customer,
supplier or other person) for which any of the Groups is responsible was in the
actual possession of one of the Groups and was in such condition that upon the
return of such property to its owner, such Group will not be liable in any
amount to such owner.

        1.22  Exhibit 1.22 includes a listing of all patents, patent
applications and trademarks owned by each of the Companies, and, to the
knowledge of Masco, includes copies of all patents and patent applications
owned by the Companies and the Subsidiary.  Each of the Groups is the sole and
exclusive owner of all patents, patent applications and trademarks listed on
Exhibit 1.22, and, to the knowledge of Masco, of all patents, patent
applications, copyrights, invention disclosures, trademarks, trade names and
service marks, whether registered or common law, and all applications therefor,
that are pending or in the process of preparation, and trade secrets, secret
processes and other proprietary rights of every kind and nature, in the United
States and in foreign countries (the "Rights") which are used or required for
use in its respective business; as of December 31, 1989 the Rights were free
and clear of any claims, liens, licenses, sublicenses, charges or encumbrances
and no governmental registration of any of the Rights had lapsed, expired or
had been canceled, abandoned, opposed or the subject of a re-examination
request.  As of December 31, 1989 there had been no claims, and, to the
knowledge of Masco, as of such date there was no basis for any claim
challenging the scope, validity or enforceability of any of such copyrights,
patents, trademarks, trade names or service marks.  There are no instances
where it has been held, claimed, or alleged, whether directly or indirectly,
and Masco has no knowledge of any basis upon which a claim may be made, that
any of the Rights of any of the Groups infringed the Rights of any third party
prior to the Effective Date, or that any activity of any third party infringed
upon any of the Rights of any of the Groups.  Prior to the Effective Date, each
of the Groups conducted its business in a manner which, to the knowledge of
Masco, was not in violation of any Right of another and did not require a
license or other proprietary right (other than licenses and other rights set
forth 

                                       -13-

in Exhibit 1.22) to so operate its business.  The manufacturing and
engineering drawings, process sheets, specifications, bills of material, trade
secrets, "know-how" and other like data of each of the Groups are in such from
and of such quality and will be so maintained so that each of the Groups can,
following the Closing, design, produce, manufacture, assemble and sell the
products and provide the services heretofore provided by them so that such
products and services meet applicable specifications and conform with the
standards of quality and cost of production standards heretofore met by each of
them.

        1.23  Masco has full power and authority to enter into this Agreement
and, subject to approval by its Board of Directors prior to the Closing, to
consummate the transactions contemplated herein.  This Agreement has been duly
executed and delivered by Masco and, subject to approval by its Board of
Directors, is a valid and binding obligation of Masco in accordance with its
terms.  Subject to approval by Masco's Board of Directors, the execution,
delivery and performance of this Agreement have been duly authorized by all
necessary corporate action of Masco and Masco Indiana, respectively.  Neither
the execution of this Agreement nor the consummation of the transactions
contemplated herein will constitute or cause a breach or violation of Masco's
or Masco Indiana's charter documents or by-laws or any covenant or obligation
binding upon Masco or Masco Indiana or affecting any of their respective
properties.  Masco has complete and unrestricted power to sell, assign and
deliver or cause to be sold, assigned and delivered to TriMas good and
marketable title to the Shares.  At the Closing there will be no restrictions
upon the vesting in TriMas of such title to the Shares, free and clear of
liens, encumbrances and other claims of any kind whatsoever, and such title
shall then vest in TriMas.

        1.24  Except as set forth on Exhibit 1.24, neither the execution of
this Agreement nor the consummation of the transactions contemplated herein
will constitute or cause a breach, default or violation of the charter
documents, by-laws or other covenants or obligations binding upon any of the
Groups or affecting any of their properties, or cause a lien or other
encumbrance to attach to any of the properties of any of the Groups, or result
in the acceleration of or the right to accelerate any obligation under or the
termination of or the right to terminate any license, franchise, lease, permit,
approval or 

                                       -14-

<PAGE>   15

agreement to which any of the Groups is a party, or require a consent of any
person to prevent such breach, default, violation, lien, encumbrance,
acceleration, right or termination.

        1.25  No approval of or filing with any court, governmental authority
or administrative agency (domestic or foreign) which is required prior to the
Closing and which has not been made or obtained is necessary to authorize the
execution and delivery of this Agreement by Masco or the consummation of the
transactions contemplated herein.

        1.26  In connection with the possible sale of any Company, Masco has
not disclosed any non-public information pertaining to any of the Groups prior
to the date hereof except under such agreements of confidentiality as Masco, in
its sole discretion, has deemed appropriate.  To the best knowledge of Masco,
no non-public information of any of the Companies has been given, during the
two years prior to the date hereof, to any competitor of any of the Companies.

        1.27  The financial records of the Groups are in such condition that,
after the Closing, historical combined financial statements for the Groups can
be prepared for calendar years 1987, 1988, and 1989 that are capable of being
audited by Coopers & Lybrand, with an opinion unqualified with respect to the
completeness of such financial statements.

        1.28  Exhibit 1.28 includes a schedule of all policies of insurance
insuring the real and personal property of the Companies and the Subsidiary and
policies insuring the Companies and the Subsidiary against risks.

        1.29  Prior to the Effective Date, Masco Indiana transferred all of the
business, assets and liabilities of its Reese Products division to Reese.

        1.30  To the knowledge of Masco, no matter has occurred since December
31, 1989 which would have been required to be disclosed pursuant to this
Agreement if such matter had existed prior to such date, except for matters
that have been disclosed on an Exhibit to this Agreement or that will be
disclosed in a certificate to be delivered to TriMas at the Closing.

                       REPRESENTATIONS AND WARRANTIES
                                  OF TRIMAS

        2.00  TriMas represents and warrants to Masco as follows:

        2.01  TriMas is a corporation duly organized, validly existing and in
good standing under the laws of the State of Delaware.

        2.02  TriMas has full corporate power to enter into this Agreement and,
subject to approval by its Board of Directors, to consummate the transactions
contemplated herein.  This Agreement has been duly executed and delivered by
TriMas and, subject to approval by its Board of Directors, is a valid and
binding obligation of TriMas in accordance with its terms.  Neither the
execution of this Agreement nor the consummation of the transactions
contemplated herein will constitute or cause a breach or violation of the
charter documents or by-laws of TriMas or of any covenants or obligations
binding upon it or affecting any of its properties.

        2.03  No approval of or filing with any court, governmental authority
or administrative agency (domestic or foreign) which is required prior to the
Closing and which has not been made or obtained is necessary to authorize the
execution of this Agreement by TriMas or the consummation of the transactions
contemplated herein.

        2.04  TriMas or its subsidiary to which its rights hereunder may be
assigned is acquiring the Shares for its own account for investment and with no
present view to distribution thereof within the meaning of the Securities Act
of 1933.

                                     III
                             COVENANTS OF MASCO

        3.00  Masco covenants and agrees that after December 31, 1989 until
Closing (except for the covenants contained in Sections 3.06, 3.07 and 3.09
which are to be performed thereafter), except with TriMas' prior written
consent or as contemplated herein:

        3.01  Except as set forth in Exhibit 1.07, each of the Groups will
carry on its business in a good and diligent manner consistent 

                                    -16-

<PAGE>   17

with prior practice in the usual and ordinary course, will not introduce
any new method of management or operation, will perform in all material respects
its obligations to be performed by it pursuant to each material agreement to
which it is bound, and will use its best efforts to preserve its business
organization intact and conserve the goodwill and relationships of its
customers, suppliers and others having business relations with it and the
services of all of its officers, employees, agents and representatives.

        3.02  Each of the Groups will maintain its corporate existence and good
standing in its jurisdiction of incorporation and in each jurisdiction in which
it is qualified to do business, and it will not amend its charter documents or
bylaws.

        3.03  Except for purchase and sales orders issued or accepted in the
ordinary course, none of the Groups will waive a material right or cancel a
material contract, debt or claim, or assume or enter into a material contract,
lease, license, obligation, indebtedness, commitment, purchase or sale and,
except in the usual and ordinary course of business, none of the Groups will
enter into or assume any other contract, lease, license, obligation,
indebtedness, commitment, purchase or sale.  For purposes of this Section 3.03
and without limiting the foregoing, all indebtedness for borrowed money, other
than intercorporate borrowings, and commitments and agreements having a duration
in excess of one year or in amounts in excess of $50,000 are deemed to be
material and not in the usual and ordinary course of business.

        3.04  Masco will, with respect to the Groups:

            (i) duly and timely file all reports and returns required to be 
      filed with any governmental agency and will promptly pay when due all
      taxes, assessments and governmental charges including interest and
      penalties levied or assessed, unless diligently contested in good faith by
      appropriate proceedings;

            (ii) cause the Groups to maintain and keep in their current 
      condition all buildings, offices, shops and other structures, and keep
      all of their machinery, tools, equipment, fixtures and other property used
      or useable in their businesses in their current condition, repair and
      working order;

                                     -17-

<PAGE>   18

            (iii) maintain in full force and effect all policies of insurance
      listed on Exhibit 1.28; and

            (iv) from the date hereof on reasonable notice afford TriMas and its
      representatives (including its counsel, accountants and other agents)
      full access at all reasonable times throughout the period prior to the
      Closing to all of their plants, offices, properties and records including
      such access as may be necessary to allow TriMas at its expense to make an
      audit or otherwise attempt to satisfy itself of the accuracy of the
      representations contained in this Agreement and that the conditions and
      warranties contained in this Agreement have been satisfied or complied
      with, and will furnish documents and all such other information concerning
      their properties, general affairs, prospects, financial condition, results
      of operations and business as TriMas may reasonably request; provided,
      however, that any investigation or inquiry made by TriMas or actual
      knowledge obtained by TriMas shall not in any way affect the
      representations and warranties contained in this Agreement or their
      survival of the Closing.

        3.05  Masco shall not take any action or omit to take any action within
its control to the extent such action or omission might result in any of the
representations or warranties contained in this Agreement being inaccurate or
incorrect on and as of the date of Closing.

        3.06  Masco will leave sufficient cash in each of the Companies and the
Subsidiary to satisfy all uncashed checks of the Groups that have been written
prior to the Closing.

        3.07  After the Closing, Masco will cooperate with TriMas in connection
with the preparation of audited combined financial statements of the Groups for
calendar years 1987, 1988 and 1989 in a timely and expeditious manner.

        3.08  From the date hereof until the termination of this Agreement,
Masco, Masco Indiana and all of the Groups will not, and Masco will use its best
efforts to ensure that the officers, directors, employees or other agents of
Masco, Masco Indiana and all of the Groups will not, directly or indirectly take
any action to solicit, initiate or encourage any offer or proposal for, or any 

                                       -18-
<PAGE>   19

indication of interest in, a merger or other business combination
involving any of the Groups or the acquisition of any equity interest in, or a
substantial portion of the assets or businesses of, any of the Groups, other
than with TriMas; provided, however, the obligation under this Section 3.08
shall terminate if Masco is notified that TriMas does not intend to consummate
the transactions contemplated under this Agreement.

        3.09  After the Closing, Masco will make awards of Masco Common Stock to
certain employees of the Groups, based on the performance of the Groups in 1989
using the Return on Assets formula in accordance with Masco's past practice.

                                      IV
                         MASCO'S CONDITIONS PRECEDENT

        4.00  All of the following shall be conditions precedent to Masco's
obligations to consummate the transactions contemplated by this Agreement:

        4.01  The representations and warranties made by TriMas herein shall be
accurate and correct in all material respects on and as of the date when made,
and on and as of the date of Closing as if made on and as of that date, and
Masco shall have received a certificate dated the date of Closing signed by
TriMas to the foregoing effect.

        4.02  Masco shall have been furnished with an opinion of Pepper,
Hamilton & Scheetz, counsel for TriMas, dated as of the Closing, to the effect
that:

        in good standing under the laws of the State of Delaware;

            (ii)  TriMas has full corporate power to enter into this Agreement 
        and to consummate the transactions contemplated herein; and

            (iii) This Agreement has been duly authorized, executed and 
        delivered by TriMas, and is its valid and binding obligation.

Such opinion may contain such qualifications as are acceptable to 

                                     -19-

Masco.

        4.03  TriMas shall have complied in all material respects with all of
its obligations under this Agreement.

        4.04  There shall not be in effect any statute, rule or regulation which
makes it illegal for Masco to consummate the transactions contemplated herein,
or any order, decree or judgment which enjoins Masco from consummating the

contemplated herein shall have been approved by the Board of Directors of Masco.

        4.05  No suit, action, or other proceeding shall be pending or
threatened before any court or governmental agency seeking to restrain, prohibit
or obtain damages or other relief in connection with this Agreement or the
consummation of the transactions contemplated herein and there shall have been
no investigation or inquiry made or commenced by any governmental agency in
connection with this Agreement or the transactions contemplated herein other
than the investigation heretofore commenced pursuant to ECRA (as hereinafter
defined).

        4.06  Masco shall have received a "fairness opinion" with respect to the
transactions contemplated by this Agreement from Salomon Brothers Inc.

                                      V
                         TRIMAS' CONDITIONS PRECEDENT

        5.00  All of the following shall be conditions precedent to TriMas'
obligations to consummate the transactions contemplated by this Agreement:

        5.01  The representations and warranties made by Masco contained in this
Agreement or in any certificate delivered to TriMas or its representatives
pursuant hereto shall be accurate and correct in all material respects on and as
of the date when made, and on and as of the date of Closing as if made on and as
of that date.

                                     -20-

<PAGE>   21

        5.03  Masco shall have complied in all material respects with all of its
obligations under this Agreement, and all of the covenants contained in Article
III hereof shall have been performed and the conditions satisfied in all
material respects.

        5.04  There shall not be in effect any statute, rule or regulation which
makes it illegal for TriMas to consummate the transactions contemplated herein

                                 TERMINATION

        6.01  This Agreement may be abandoned or terminated on or before the
Closing by mutual agreement of Masco and TriMas.

        6.02  In addition to TriMas' rights provided elsewhere in this Article
VI, either Masco or TriMas may terminate this Agreement at any time prior to the
Closing by giving the other party written notice thereof, if and only if:

            (i)   there is a breach of or failure by the party not terminating
      to perform in any material respect any of the warranties,
      representations, commitments, covenants or conditions under this
      Agreement; or

            (ii)  there exists any material error, misstatement or omission 
      on the part of the party not terminating which renders any Exhibit,
      representations, document, information or Schedule delivered in connection
      herewith misleading to the party terminating this Agreement.

Such notice shall clearly specify the breach or failure of such notified
party to perform or satisfy its warranties, representations, commitments,
covenants and conditions, or the material error, misstatement or omission of the
notified party.

        6.03  By an instrument in writing delivered to the other party either
Masco or TriMas may waive any condition precedent, covenant or condition
contained herein for the benefit of the party delivering such waiver, and upon
the exercise of such right of waiver, the transactions shall be closed in
accordance with the terms contained in this Agreement as modified by such
waiver.

        6.04  If this Agreement is abandoned or terminated as provided in
Section 6.01, this Agreement shall forthwith become wholly void and of no
effect, without liability of either party to the other.

        6.05  Regardless of whether the transactions contemplated by this
Agreement are consummated, each party shall pay all fees and expenses incurred
by such party in connection herewith, except that Masco shall reimburse TriMas
for the reasonable expenses of TriMas' counsel (which shall include the expenses
of such counsel's 

                                     -22-

environmental consultants, not to exceed $30,000).  Masco and TriMas shall each
pay one-half of any documentary, stamp or transfer taxes incurred in connection
with the transactions contemplated by this Agreement, except that Masco shall be
responsible for such taxes and other expenses relating to the transfer of the
Reese Products division assets from Masco Indiana to Reese.

        6.06  If (i) a condition precedent stated in Section 5.01 is not
satisfied, (ii) Masco in its certificate to be delivered under Section 5.07
specifically describes the representation or warranty contained in this
Agreement or in any certificate delivered to TriMas or its representatives
pursuant hereto which is not accurate or correct in all material respects as of
the date thereof, and (iii) TriMas at any time thereafter proceeds with the
Closing notwithstanding such unsatisfied condition, inaccuracy or incorrectness,
then, unless otherwise then or thereafter agreed to in writing by Masco and
TriMas, Masco shall have no liability to TriMas or any other party indemnified
pursuant to Section 8.01 with respect to the condition precedent which is not
satisfied or the inaccuracy or incorrectness described in such certificate.

                                   CLOSING

        7.01  Subject to the terms and conditions of this Agreement, Masco
agrees to sell, transfer and convey, or cause the sale, transfer and conveyance
and TriMas hereby agrees to purchase, the Shares.  Said purchase and the closing
of the transactions contemplated hereby (the "Closing") shall take place on
January 30, 1990, unless this Agreement shall have theretofore terminated as
herein provided.  The transactions contemplated by this Agreement shall be
effective as of January 1, 1990 (the "Effective Date").  Subject to the terms
and conditions of this Agreement, each party agrees to use best efforts to take
or cause to be taken, all actions and to do, or cause to be done, all things
necessary, proper or advisable, to cause the Closing to be timely consummated.

        7.02  At the Closing, Masco shall deliver to TriMas certificates
representing all of the Shares (without any restrictive legend thereon),
endorsed in blank or with accompanying stock powers duly signed.

                                     -23-


<PAGE>   24

        7.03  Contemporaneously with the Closing such of the directors and
officers of each of the Groups as may be requested by TriMas shall resign.

        7.04  Except as provided in Section 7.06, the aggregate purchase price
payable hereunder for all of the Shares shall be $77 million (the "Purchase
Price"), payable on the date of Closing by wire transfer or intrabank transfer
to Masco.  All payments made by TriMas for the Shares and payments made pursuant
to Section 7.05 shall be paid to Masco or pursuant to Masco's direction.  Masco
agrees to allocate to Masco Indiana the appropriate portion of the Purchase
Price and any Additional Payment and Contingent Purchase Price Payment, both as
hereinafter defined, and any interest thereon, for the Shares that Masco Indiana
is transferring pursuant to this Agreement, and to indemnify TriMas for the
failure to do so or for an incorrect allocation.

        7.05(a) Masco agrees that the aggregate "Net Worth", as hereinafter
defined, of the Groups transferred by Masco and Masco Indiana to TriMas will be
$47 million as of the Effective Date.  If, after completion of the review
referred to below, a final determination is made that the Net Worth exceeds $47
million, then TriMas shall pay to Masco within ten days after such determination
becomes final the difference between the Net Worth, as so determined, and $47
million.  If, after completion of the review referred to below, a final
determination is made that the Net Worth is less than $47 million, then Masco
shall pay to TriMas or, at TriMas' direction, the Groups, within ten days after
such determination becomes final the difference between $47 million and the Net
Worth, as so determined.  The Net Worth determination shall be conclusive and
binding on TriMas unless TriMas shall give notice of its objection thereto to
Masco within sixty days after the date of Closing.   If TriMas shall not agree
with the determination of Net Worth, TriMas shall, within such sixty day period,
give written notice of such fact to Masco, such notice to contain in reasonable
detail the reasons for such objection, and unless within fifteen days of receipt
by Masco of such objection the matters in dispute shall be resolved by mutual
agreement, either Masco or TriMas may within ten days after the expiration of
such fifteen day period submit the December Balance Sheets and all changes
proposed by either party thereto to Coopers & Lybrand, independent public
accountants.  Upon any such request, such accountants shall either confirm the
determination of Net Worth or make such changes therein

                                     -24-

<PAGE>   25

as they deem appropriate with respect to such proposed changes in
accordance with this Section 7.05, and, after such review and any such change,
such determination shall, except as provided below, be conclusive and binding
upon the parties hereto.  Masco and TriMas will each pay one-half of the
expenses incurred in connection with retaining Coopers & Lybrand to resolve any
disputes as provided under this Section 7.05. If Masco or TriMas is not
satisfied with the determination of Coopers & Lybrand and gives notice of such
fact and the specific objections thereto to the other within 10 days after the
receipt of such determination by Coopers & Lybrand, Masco and TriMas agree to
select another "big six" firm of independent certified accountants of recognized
standing reasonably acceptable to TriMas and Masco to review the matters
previously submitted to Coopers & Lybrand.  Such  accountants shall either
confirm the determination of Coopers & Lybrand with respect to the matters
subject to their review or make such changes therein as they deem appropriate in
accordance with this Section 7.05, and, after such review and any such change by
such accountants, such determination shall be conclusive and binding upon the
parties hereto.  The party requesting review by such other "big six" firm shall
pay the expenses incurred in connection therewith except that if such party
shall substantially prevail (as determined by such firm) all such expenses shall
be borne by the other party.  For purposes of this Section 7.05, "Net Worth" for
each Group is defined as the aggregate of the assets, less the liabilities, of
such Group as reflected on the December Balance Sheet of such Group, determined
by utilizing the accounting policies, practices and agreement set forth on
Exhibit 1.04(b), and as to matters not set forth thereon, by utilizing the
accounting policies and practices used by the Groups prior to the Effective
Date, as long as such policies and practices not set forth on Exhibit 1.04(b)
are in accordance with generally accepted accounting principles.  In determining
Net Worth, neither Masco nor TriMas may dispute any of the accounting policies,
practices or agreements specifically set forth on Exhibit 1.04(b), and such
matters shall not be reviewed by Coopers & Lybrand or any other firm of
independent certified accountants reviewing the December Balance Sheets.  TriMas
shall have no claim under Section 8.01 of this Agreement with respect to any
matter for which an adjustment is made pursuant to this Section 7.05 to the
extent of such adjustment.

      (b)   From and after the Effective Date, the Groups have been and shall be
operated by Masco at the expense of and for the

benefit of TriMas.  In connection therewith, promptly after the Closing,
the parties agree to reconcile, for the period from the Effective Date to the
date of Closing, the amount of cash collected on behalf of each of the Companies
and the Subsidiary by Masco and  Masco Indiana, and the amount of cash
contributed or expended by Masco and Masco Indiana (including any cash left in
the Groups pursuant to Section 3.06) to or for the benefit of the Companies and
the Subsidiary.  The amount of such cash contributed or expended by Masco and
Masco Indiana in excess of the amount it has collected will be reimbursed by
TriMas to Masco.  Likewise, the amount of such cash collected by Masco and Masco
Indiana in excess of the amounts contributed or expended by Masco and Masco
Indiana will be reimbursed to TriMas or, at TriMas' direction, the Groups, by
Masco.  Charges for specific services rendered or paid (such as insurance
premiums and similar items) by or on behalf of Masco for the Groups relating to
activities after December 31, 1989 shall be deemed an expense of the Groups in
accordance with Masco's past practice, prorated if appropriate based on the
number of days from the Effective Date to the day prior to Closing, except that
no management fee shall be charged by Masco for such period and in lieu thereof
the Groups shall be deemed subject to the Corporate Services Agreement between
Masco and TriMas dated as of December 27, 1988, effective as of the Effective
Date.

        7.06(a) In addition to the amounts provided under Section 7.04 and
clause (b) of this Section 7.06, TriMas shall pay to Masco the sum of $6 million
(the "Additional Payment") if the average of the annual Pre-Tax Income, as
hereinafter defined, for any two or more consecutive calendar years, the first
of which is 1990 and the last of which is 1991, 1992, 1993 or 1994, equals or
exceeds $12 million.  The total amount payable under this clause (a) shall be
deemed earned after the earliest calendar year that the requirements set forth
in the preceding sentence have been met.

        (b)   In addition to the amounts provided under Section 7.04 and clause
(a) of this Section 7.06, TriMas shall pay to Masco, if entitled thereto under
the terms and conditions contained herein, the following amounts ("Contingent
Purchase Price Payments"), provided, however, that excluding the interest
payments provided under clause (e) below, the total aggregate amount payable
under this clause (b) of Section 7.06 shall not exceed $12 million:

              (i)   the product of (A) seven, multiplied by (B) the 

                                     -26-

<PAGE>   27

      amount by which the average of the annual Pre-Tax Income for calender
      years 1990, 1991 and 1992 exceeds $13 million;

            (ii)  if the amount payable to Masco pursuant to subclause (i) above
      is less than $12 million, excluding interest, then (A) the product of
      (1) seven, multiplied by (2) the amount by which the average of the annual
      Pre-Tax Income for calendar years 1990, 1991, 1992 and 1993 exceeds $13
      million, less (B) the amount paid pursuant to subclause (i) above
      excluding interest;

            (iii) if the amounts payable to Masco pursuant to subclauses (i) and
      (ii) above aggregate less than $12 million, excluding interest, then (A)
      the product of (1) seven, multiplied by (2) the amount by which the
      average of the annual Pre-Tax Income for calendar years 1990, 1991, 1992,
      1993 and 1994 exceeds $13 million, less (B) the amounts paid pursuant to
      subclauses (i) and (ii) above excluding interest.

      (c)   As used herein, the following terms have the respective meanings set
forth below:

            "Pre-Tax Income" for any period shall mean the income of the 
      Combined Companies, considered as an independent corporate entity, prior
      to any deduction for foreign, Federal, state and local taxes measured by
      earnings or gross income, and any deduction for the Michigan Single
      Business tax, and prior to reflecting the inclusion of any income tax
      credits, all determined in accordance with the accounting policies,
      practices and agreements specifically described on Exhibit 1.04(b), and as
      to matters not set forth thereon, the accounting policies and practices
      utilized by the Groups prior to the Effective Date as long as such
      accounting policies and practices not set forth on Exhibit 1.04(b) are in
      accordance with generally accepted accounting principles consistently
      applied, but with the following adjustments:

                  (1) Except as set forth in clause (3) below, the amount of any
            extraordinary gain or extraordinary loss or any gain or loss
            from the sale, exchange or other disposition of property (other than
            inventory sold in the ordinary course of business) shall not be
            taken into account in determining Pre-Tax Income.

                                     -27-
<PAGE>   28

                  (2) If TriMas directly or through a subsidiary makes a
            contribution to the capital of or otherwise directly or through
            a subsidiary loans funds to the Combined Companies or charges the
            Combined Companies for taxes (other than taxes accrued in the
            December Balance Sheets) which would have been payable or accruable
            by the Combined Companies if they were an independent corporate
            entity, such contribution, funds or charges will be deemed to be
            debt owed to TriMas bearing interest at a rate equal to the prime
            rate of interest at National Bank of Detroit to major corporate
            customers (as such rate prevails from time to time while such debt
            is deemed to be outstanding).  Such assumed interest expense shall
            be deemed an additional expense for the Combined Companies for the
            period during which such contribution, funds or charges are
            outstanding from or unpaid to TriMas.

                  (3) If TriMas sells any of the companies in the Combined
            Companies, or the assets thereof, as an entirety or
            substantially as an entirety, the gross proceeds of such sale will
            be deemed to be debt owed to the Combined Companies bearing interest
            from the date of sale at the rate of fourteen (14%) percent per
            annum payable quarterly and such deemed interest shall be deemed to
            be debt owed to the Combined Companies bearing interest from the
            deemed date of payment thereof at the rate set forth in the next
            sentence.  If the Combined Companies pay a dividend or make a
            distribution, or otherwise loan funds to TriMas or any subsidiary of
            TriMas, such dividend, distribution or loan will be deemed to be
            debt owed to the Combined Companies bearing interest at a rate equal
            to two percentage points under the prime rate of interest at
            National Bank of Detroit to major corporate customers (as such rate
            prevails from time to time while such debt is deemed to be
            outstanding).  Such assumed interest income described in the
            preceding two sentences shall be added in determining Pre-Tax Income
            for the period during which such proceeds, dividend, distribution or
            loan were outstanding from or paid by the Combined Companies.  To
            the extent the Combined Companies are not directly liable for any
            taxes which would otherwise have been payable or accruable had the
            Combined Companies existed as an independent corporate entity, any
            payments to TriMas or  

                                     -28-


<PAGE>   29
                                         
            to any subsidiary of TriMas of funds equal to such taxes shall not,
            for purposes of this clause, be deemed to be a distribution or
            property paid or otherwise made available from the Combined
            Companies.

                  (4) Assets of the Combined Companies shall be valued in
            accordance with accounting principles consistently applied which
            were used by the Groups in the Financial Statements as of December
            31, 1989 and without considering any adjustment to asset values from
            any allocation by TriMas of the Purchase Price, Additional Payment
            or Contingent Purchase Price Payments as though the acquisition by
            TriMas of the Combined Companies had not been effected.

                  (5) TriMas may charge a management fee to the Combined 
            Companies not to exceed one percent of net sales of the Combined
            Companies, and such amount shall be deemed an expense in determining
            Pre-Tax Income, and charges for specific services rendered or paid
            by or on behalf of TriMas or a subsidiary for the Combined Companies
            in conformity with the past practices of Masco with respect to the
            Combined Companies shall be deemed an expense of the Combined
            Companies for the period in which such services were rendered.

                  (6) If TriMas establishes an accrued liability or asset value
            reduction as of the Effective Date in connection with the
            acquisition of the Groups on account of the possible consolidation
            of certain of the operations of the Combined Companies, whereby such
            amount is not deemed an expense in determining Pre-Tax Income, and
            if thereafter any excess of such accrued liability or asset value
            reductions eliminated in a manner whereby income is increased as a
            result of the elimination of such excess accrued liability or asset
            value reduction, the income resulting from such elimination shall be
            excluded for purposes of determining Pre-Tax Income.

                  (7) To the extent Masco indemnifies TriMas or any of the 
            Groups for any claim, liability, obligation, loss, damage,
            assessment, judgment, cost or expense under this Agreement or pays
            any expense required under this 

                                     -29-
<PAGE>   30

            Agreement, such claim, liability, obligation, loss, damage,
            assessment, judgment, cost or expense shall not be deemed an
            expense or loss for purposes of determining Pre-Tax Income, and the
            receipt of any such indemnification payment from Masco shall not be
            deemed income for purposes of determining Pre-Tax Income.

        (d)   The parties hereto recognize, by reason of the Combined Companies'
integration into the consolidated operations of TriMas, that certain adjustments
to Pre-Tax Income may be necessary, in addition to the types of adjustments set
forth above, in order that the calculation of Pre-Tax Income will not be
distorted from the calculation which would be made if the Combined Companies
were considered under generally accepted accounting principles to be an
independent corporate entity.  All determinations for the Combined Companies
under this Section 7.06, including all adjustments thereto to prevent any such
distortion in Pre-Tax Income and other determinations, shall be made and
reported to TriMas and Masco by the internal audit staff utilized by TriMas
within 120 days after the end of the period for which such determination is
being made.  The determination of such internal audit staff shall be conclusive
and binding upon the parties hereto on the sixtieth day thereafter (or such
earlier date as TriMas is advised by Masco that Masco accepts such determination
as conclusive and binding) unless Masco within such sixty-day period submits all
its proposed changes to Coopers & Lybrand, independent certified public
accountants.  Within fifteen days following Masco's submission, TriMas may
submit proposed changes to Coopers & Lybrand.  Upon any such request, such
accountants shall either confirm such original determination or make such
changes therein as they deem appropriate with respect to such proposed changes
raised by either party hereto in accordance with this Section 7.06, and, after
such review and any such change, such determination shall be conclusive and
binding upon the parties hereto, except as provided below.  Masco and TriMas
will each pay one-half of the expenses incurred in connection with retaining
Coopers & Lybrand to resolve any disputes as provided under this Section 7.06. 
If Masco or TriMas is not satisfied with the determination of Coopers & Lybrand
and gives notice of such fact and the specific objections thereto to the other
within 10 days after the receipt of such determination by Coopers & Lybrand,
Masco and TriMas agree to select another "big six" firm of independent certified
accountants of recognized standing reasonably acceptable to TriMas and Masco to
review the matters in dispute.  Such 

                                     -30-

<PAGE>   31

accountants shall either confirm the determination of Coopers & Lybrand
with respect to the matters subject to their review or make such changes therein
as they deem appropriate in accordance with this Section 7.06, and, after such
review and any such change, such determination shall be conclusive and binding
upon the parties hereto.  The party requesting review by such other "big six"
firm shall pay the expenses incurred in connection therewith except that if such
party shall substantially prevail in its position (as determined by such firm)
all such expenses shall be borne by the other party.

        (e)   Any payments owed pursuant to this Section 7.06 shall be paid
within thirty days after the determination has become conclusive and binding on
the parties in accordance with clause (d) above that such payment is due to
Masco.  Such payments shall be made by wire transfer or intrabank transfer to
Masco.  Any payments made pursuant to clause (a) or (b) of this Section 7.06
shall bear interest from the Effective Date until paid at the rate of 8.06% per
annum, compounded annually, with such interest payable concurrently with such
payments.

        7.07  From and after the Effective Date, the treatment of existing
health and welfare benefits as well as existing stock awards and stock options
of employees of the Groups will be as described on Schedule III hereto.

        7.08  At the Closing, the parties shall execute and shall cause the
Companies, as required, to execute the administrative consent order in the form
proposed by the State of New Jersey and shall execute such other documents as
may be reasonably required under ECRA.

                                     VIII
                       INDEMNIFICATION AND TAX MATTERS


        8.01  Subject to the provisions of Section 6.06 and Exhibit 1.04(b),
Masco shall indemnify,  defend and hold harmless TriMas, the Groups and their
respective affiliates and the respective officers, directors, employees and
shareholders of the foregoing (other than Masco and Masco Indiana) from, against
and with respect to any claim, liability, obligation, loss, damage, assessment,
judgment, cost and expense (including, without limitation, 

                                     -31-

reasonably incurred in investigating, preparing, defending against, settling or
prosecuting any litigation or claim, action, suit, proceeding or demand), of any
kind or character, arising out of or in any manner incident, relating or
attributable to (and after giving effect to (a) any proceeds from insurance
received (other than self-assurance and insurance which is retrospectively
rated), and (b) any amount reflected or reserved therefor in the December
Balance Sheets) (i) any inaccuracy in any representation or breach of warranty
of Masco contained in this Agreement or in any certificate, instrument of
transfer or other document or agreement executed by Masco or any of the Groups
in connection with this Agreement, (ii) any failure by Masco to perform or
observe, or to have performed or observed any covenant, agreement or condition
to be performed or observed by Masco under this Agreement or under any
certificate or other documents, instrument of transfer or agreement executed by
Masco or any of the Groups in connection with this Agreement, (iii) (a) the
matters disclosed on Exhibit 1.14(c) to the extent provided therein, and (b)
remediation or clean-up obligations of any of the Groups and their respective
officers, directors, employees or shareholders in their capacities as such, for
(1) the presence of hazardous or toxic wastes, substances or similar materials
in the soil or ground water on, in, under or above property now or previously
owned or leased by any of the Groups; or (2) the contamination of any property
belonging to other parties with hazardous or toxic wastes, substances or similar
materials insofar as such contamination is the result of the handling, storage,
use, disposal, delivery for disposal or generation of any such hazardous or
toxic wastes, substances or similar materials at any time prior to the Effective
Date by or on behalf of any of the Groups, in each such case, regardless of the
accuracy of the representations and warranties contained in Section 1.14 hereof
or disclosures made on Exhibit 1.14(c) (except as otherwise set forth therein),
(iv) any agreements, contracts, negotiations or other dealings by Masco with any
person concerning the sale of the capital stock or business of any of the
Groups, (v) any guaranty to which any of the Groups is a party and which
guarantees amounts payable by, or obligations of, any person or entity other
than such Groups but in any event only insofar as such guaranty arises out of
transactions prior to the Effective Date and is not reflected as a liability in
the December Balance Sheets, (vi) the matters disclosed on Exhibit 1.18, (vii)
any deferred Federal, state and local income tax liability of each of the Groups

                                     -32-


<PAGE>   33

relating to any period prior to the Effective Date, (viii) any liability
for damage to persons or property caused by acts or omissions of any of the
Groups prior to the Effective Date, (ix) any liability incurred by the Reese
Group in connection with the transfer of the assets of the Reese Products
division of Masco Indiana to Reese, or (x) any liability of any of the Groups on
account of product warranties for products or services manufactured, sold,
provided, or performed by or on behalf of any of the Groups prior to the
Effective Date.

8.02  Notwithstanding the provisions of Section 8.01:

        (A) TriMas shall have no right to make a claim under this Agreement
except for the amount by which the aggregate of all claims thereunder which have
not theretofore been reimbursed to TriMas and which TriMas would have been
entitled to assert against Masco absent this Section 8.02, exceeds $900,000
("Basket Amount") as adjusted pursuant to clause 8.02(C) below; provided,
however, that the foregoing limitations shall not apply to any claim for
indemnification arising out of or in any manner incident, relating or
attributable to (i) any inaccuracy or incorrectness in any representations or
warranties or any breach of any covenants contained in Sections 1.02, 1.03,
1.23, 1.25, 7.04, 8.10, 8.11, 8.12 or 9.01, (ii) a willful and intentional
breach of, or failure to perform as a result of gross negligence, a covenant to
be performed by Masco prior to he Closing, (iii) any claim arising under clauses
(iv), (vi), (vii) or (ix) of Section 8.01, (iv) the matters disclosed on Exhibit
1.14(c) to the extent set forth thereon, (v) costs arising which relate to
remedial action required in order to obtain approval of the transactions
contemplated herein under the New Jersey Environmental Clean-up Responsibility
Act of 1983 ("ECRA") or (vi) the amount of expense relating to the Reese Group's
obligation to repair or replace defective products under product warranties in
the three-year period 1990 through 1992, if any, in excess of $375,000, and less
than $530,000.  Notwithstanding the foregoing or the provisions of Section 9.03,
Masco shall have the right at its election to reimburse TriMas for amounts for
which it is not otherwise obligated to reimburse TriMas as a result of the
Basket Amount or as a result of the termination of the obligation to indemnify
as set forth in Section 9.03, provided that Masco shall also pay TriMas interest
on such amounts at the rate of 8.06 percent per annum, compounded annually, from
the date of the loss giving rise to such indemnity until paid.

                                     -33-


<PAGE>   34


        (B)   Masco shall have no responsibility or liability for, and shall
have no indemnification obligation under Section 8.01 or otherwise on account
of, the ownership or conduct of the businesses of the Groups from and after the
Effective Date (including without limitation the continuation of conduct engaged
in prior to the Effective Date), except to the extent that such may exist for
the breach of any representation which specifically relates to the period after
the Effective Date and prior to the Closing in Sections 1.07, 1.08, 1.14 and
1.30 or for breach of a covenant or a specific indemnification obligation of
Masco to be performed after the Closing.

        (C)   If TriMas or any of the Groups receives a tax benefit as a result
of a matter subject to an indemnification claim under Section 8.01, TriMas shall
apply such tax benefit when realized by TriMas as follows:

            (i)   TriMas shall pay to Masco an amount equal to the lessor of: 
      (a) the amount of such tax benefit or (b) amounts previously paid by
      Masco to TriMas pursuant to Section 8.01.

            (ii)  To the extent any such tax benefit exceeds the amount paid to
      Masco pursuant to subclause (i) above, the amount of such excess shall
      be an additional Basket Amount.

            (iii) If any such tax benefit is later disallowed by the taxing
      authority, then Masco shall promptly refund to TriMas the amount of any
      payment to Masco pursuant to subclause (i) above plus interest charged by
      the taxing authority on such disallowed tax benefit, and any adjustment to
      the Basket Amount on account of such tax benefit under subclause (ii)
      above shall be reversed and eliminated and Masco shall promptly pay to
      TriMas any payment which may be due as a result of the elimination of such
      adjustment to the Basket Amount.

        (D)   The right of indemnification provided in Section 8.01 is solely
for the benefit of the parties referred to therein, and such right will not be
extended directly or indirectly, to any other person.

        (E)   To the extent Exhibit 1.14(c) specifically limits or  excludes
Masco's indemnification obligation for certain matters, 

                                     -34-

<PAGE>   35

Masco shall have no indemnification obligation for such matters under other
provisions of this Agreement.

        8.03  If Masco is required to make or otherwise makes any payments to
TriMas as a result of the inaccuracy of the representations contained in Section
1.20 relating to the collection of receivables, TriMas shall, concurrently with
such payment, assign to Masco all of its title to and the right to collect the
amount of the accounts receivable for which payment in any equal amount was made
to TriMas by Masco.  If any Group has receivables arising from unrecorded sales
as of the Effective Date in excess of those reflected on its December Balance
Sheet, Masco shall have the benefit thereof and TriMas shall at Masco's expense,
assist Masco in the collection thereof provided that such collection effort does
not unreasonably interfere with the business relationship between the Group and
the account debtors.

        8.04  TriMas shall give Masco prompt notice of any claim for which
indemnification may be sought by TriMas under Section 8.01 notwithstanding the
fat that such claim would be subject to the Basket Amount.  Masco shall at its
own expense assume the defense of all claims for which it either is obligated to
indemnify TriMas or elects to indemnify TriMas, with counsel of its choice. 
TriMas shall have the right to employ its own counsel in any such case at its
own expense.  TriMas agrees to cooperate with Masco in connection with any claim
for which Masco is providing indemnification hereunder.  Masco shall have the
absolute right to settle at Masco's expense any claim, except for any settlement
wherein criminal liability is admitted or which involves any action other than
the payment of money, and in either such case, only with the prior written
consent of TriMas.

        8.05  If a final determination is made that Masco is obligated to
provide indemnification under Section 8.01 hereof, then Masco agrees to make any
such indemnification payment promptly after such final determination is made. 
If Masco fails to make any such indemnification payment which is owing to TriMas
or any of the Groups within 30 days after such determination becomes final,
TriMas shall have the right to off-set such amount against amounts owing to
Masco by TriMas under this Agreement in addition to any other remedy which
TriMas may have.

        8.06  TriMas shall file all tax returns or reports for the 

                                     -35-


<PAGE>   36

Groups with respect to any taxable period which ends after the Effective
Date (except for any consolidated or combined return which reports income of
Masco), provided that any tax liability with respect to a taxable period that
began prior to the Effective Date shall be allocated between Masco and TriMas in
accordance with the following provisions, and, provided, however, that Masco
will receive as a credit to amounts allocated to it all amounts relating to such
tax liability which are accrued on the Financial Statements.

            (A)   In the case of any tax based on income of the Groups or any
      sales or use tax, the tax liability shall be divided between Masco and
      TriMas such that the tax liability attributable to income earned or sales
      made before the Effective Date shall be allocated to Masco and any tax
      liability attributed to income earned or sales made on or after the
      Effective Date shall be allocated to TriMas.

            (B)   In the case of real estate tax, or other tax not based upon
      income or sales, the tax liability shall be divided between Masco and
      TriMas such that TriMas shall pay that portion of the tax liability
      determined on the basis of the number of days in the taxable period after
      the Effective Date divided by the total number of days in the taxable
      period and Masco shall pay that portion of the tax liability determined
      on the basis of the number of days in the tax period up to and including
      the Effective Date divided by the total number of days in the taxable
      period.

        8.07  Masco shall be entitled to any refund of any taxes attributable to
the Groups for all periods ending before the Effective Date including interest
thereon, and shall be paid any such refund, including interest thereon, promptly
upon receipt thereof by TriMas or any of the Groups.  Masco shall have the right
to determine whether any such claim for refund of such taxes shall be made on
behalf of the Groups.  If Masco elects to make such a claim for refund, Masco
shall bear the full expense of the making of such claim, shall reimburse TriMas
or the Groups for the reasonable out-of-pocket expenses incurred by them in
assisting in such claim, and TriMas and the Groups shall cooperate fully in
connection with making such a claim.  In the event any Group incurs a net
operating loss after the Effective Date which is carried back 

                                     -36-

<PAGE>   37

to a prior period of any Group, Masco shall pay to the Group who
incurred the net operating loss any such refund, including interest thereon,
received by Masco or its affiliates, promptly upon receipt thereof, or shall pay
to such Group the amount of any reduction in tax liability that Masco obtains as
a consequence of such carryback and any such payment shall not be included in
Pre-Tax Income under Section 7.06.

        8.08  (a)   Masco shall have exclusive authority, through counsel and
other representatives of its choice, to control, compromise or settle any audit
or other examination by any governmental body or any judicial or administrative
proceeding relating to liability for taxes ("Tax Contest") with respect to which
(1) a consolidated tax return or any other consolidated or combined tax return
including any of the Groups for any period beginning before the Effective Date
was filed, or (2) a separate tax return was filed for any of the Groups for any
period ending on or before the Effective Date, except that in either case with
respect to any item which may affect the Groups for any period after the
Effective Date Masco must obtain the agreement of TriMas prior to a compromise
or settlement of the matter, which agreement will not be unreasonably withheld
by TriMas.  TriMas shall promptly notify Masco of any notice TriMas or any of
the Groups receives after the Closing of any threatened or pending Tax Contest
or any proposed adjustment attributable to any such Tax Contest.  TriMas and the
Groups shall deliver to Masco any power of attorney required to allow Masco and
its counsel and other representatives to represent any of the Groups in
connection with any Tax Contest and shall use their best efforts to provide
Masco with such assistance as may be reasonably requested by Masco in connection
therewith.  Masco shall reimburse TriMas for reasonable out-of-pocket expenses
incurred by it in providing such assistance.

(b)   For any Tax Contest involving a tax liability for a period beginning 
before the Effective Date and ending after the Effective Date, TriMas
shall have exclusive authority, through counsel and other representatives of its
choice, to control, compromise or settle such Tax Contest, and any taxes owed or
professional fees incurred therewith shall be apportioned between TriMas and
Masco as set forth in Section 8.06.

(c)   If as a result of any Tax Contest (other than pertaining to the making of
the Section 338(h)(10) election pursuant to Section 

                                     -37-

<PAGE>   38

8.09 hereof or the increase in tax basis received by TriMas pursuant to
such election), Masco incurs additional income tax liability but TriMas receives
a related tax benefit in the form of an increase in tax basis or otherwise, such
tax benefit shall be equitably apportioned between Masco and TriMas.  Likewise,
if as a result of any Tax Contest, TriMas incurs additional income tax liability
and Masco receives a related benefit, such tax benefit shall be equitably
apportioned between Masco and TriMas.

        8.09  At TriMas' request, Masco will make an effective election under
Section 338(h)(10) of the Internal Revenue Code relating to the transactions
contemplated hereby.
      
        8.10  At the request of Masco, TriMas agrees to cause Fulton to withhold
amounts owing by Fulton to the former stockholder of the Subsidiary, provided,
however, that if Masco makes such a request, Masco will indemnify and hold
TriMas and Fulton harmless against any liability relating to the withholding of
such amounts.  TriMas agrees to indemnify and hold Masco harmless with respect
to (i) any liability incurred by Masco under the guarantee provided to the
former stockholder of the Subsidiary in connection with the purchase of the
Subsidiary by Fulton, except for liability arising form the above withholding,
at the request of Masco, of amounts owing by Fulton to such former stockholder,
(ii) any liability incurred by Masco with respect to guarantees issued to third
parties by Masco for the benefit of any of the Companies or the Subsidiary, and
(iii) any liability relating to any matter as to which any Group is responsible
and which is not then subject to indemnification by Masco hereunder.

        8.11  Masco shall be responsible for the filing of returns for, and
payment of, all 1989 local, state and Federal income taxes for all of the
Groups.  Masco will file all such returns and pay such income taxes in a timely
manner.  TriMas shall be responsible for the filing of returns for, and payment
of, all other 1989 taxes for all of the Groups, provided, however, that Masco
will promptly reimburse TriMas for any amount paid by TriMas for such other 1989
tax which is not reflected as a liability in the December Balance Sheets.  If,
however, such liability reflected in the December Balance Sheets exceeds the
amount of such other 1989 taxes, such excess shall be promptly paid to Masco by
TriMas.

        8.12  Masco shall perform all investigative and remedial 

                                     -38-

<PAGE>   39


measures required by the New Jersey Department of Environmental Protection 
for compliance with ECRA, at its sole expense (except for measures
set forth on Exhibit 1.14(c) to be performed at TriMas' expense), and shall have
the responsibility, at its sole expense, to negotiate with and make all
necessary filings and submissions regarding ECRA.  Masco shall also, at its sole
expense, perform all of its other obligations described in Exhibit 1.14(c). 
Notwithstanding the foregoing, Masco shall consult with TriMas with respect to
such matters and provide TriMas with a complete copy of each filing or
submission at the time it is made.  TriMas agrees to cooperate with Masco in
connection with the compliance with ECRA and any remediation which may be
required in connection therewith or any other laws, rules or regulations
relating to environmental matters or with respect to the matters described in
Exhibit 1.14(c) as to which Masco has an obligation to perform, provided,
however that Masco will not take any action which will unduly hamper the ability
of the Groups to carry on their respective businesses in the ordinary course. 
Notwithstanding the foregoing, if any capital expenditures are required in
connection with any such remediation, and such capital expenditures will provide
efficiencies to any Group which will result in decreased capital or operating
costs unrelated to environmental compliance in the future, TriMas will, promptly
after such capital expenditures are made, pay to Masco the present value of the
amount of savings which will be realized by any Group as a result of such
decreased costs, provided, however, that such payment shall not exceed the
amount of such capital expenditure.

                                      IX
                                   GENERAL

        9.01  Except for services of Salomon Brothers Inc, the cost for which
Masco will pay, Masco represents and warrants to TriMas that the services of a
broker or finder have not been used by Masco in connection with any of the
matters pertaining to the transactions contemplated herein and that no broker's,
finder's or financial advisor's fee will become payable by TriMas or any of the
Groups by reason of the execution of this Agreement or the consummation of the
transactions contemplated herein and arising out of the acts or omissions of
Masco.  Masco will hold harmless and indemnify TriMas, each of the Groups and
their respective affiliates and the officers, directors, employees and
shareholders of the foregoing (other than Masco and Masco Indiana) from and
against any claim for

                                     -39-


<PAGE>   40

broker's, finder's or financial advisor's fees, including costs or expenses 
incurred in connection with the defense of any suit claiming such fees,
or in any other manner pertaining to claims for such fees, which may become
payable by reason of the acts or omissions of Masco.  TriMas retained the
services of PaineWebber Incorporated in connection with the transactions
contemplated by this Agreement, the cost of which will be paid by TriMas. 
TriMas shall hold harmless and indemnify Masco from and against any claim for
broker's, finder's, or financial advisor's fees, including costs or expenses
incurred in connection with the defense of any suit claiming such fees, or in
any other manner pertaining to claims for such fees, which may become payable by
Masco solely by reason of the acts or omissions of TriMas.
      
        9.02  This Agreement shall be construed, interpreted and rights of the
parties determined in accordance with the laws of the State of Michigan.

        9.03   The representations, warranties and other agreements herein
contained shall continue in full force and effect after the Closing
notwithstanding any investigation by a party hereto or such party's actual
knowledge of any inaccuracy in any representation or warranty, subject to
Section 6.06, (i) without termination in the case of those contained in Sections
1.02, 1.03, 1.23, 1.25, 7.04, 8.10, 8.11, 8.12 and 9.01 and clauses (iii) (a),
(iv), (vi), (vii) and (ix) of Section 8.01 and clauses (C) and (D) of Section
8.02, (ii) in the case of those contained in Section 1.06, 8.06, 8.07, 8.08 and
8.09, until the expiration of the statute of limitations (including any
extensions) applicable to tax returns relating to any period prior to the
Effective Date, (iii) in the case of those contained in Section 1.19 which
relate to compliance with ERISA, until the expiration of the statue of
limitations (including any extensions) contained in ERISA, and (iv) until the
date which is three years (or such longer period as specifically provided
herein) after the Effective Date in the case of all other representations,
warranties, and agreements contained herein.  No claim for indemnity may be made
on account of the inaccuracy or incorrectness of any representation, warranty or
agreement contained herein unless prior to the expiration for the survival
period the party claiming indemnity has given notice to the party against whom
indemnification is sought.  Any claim timely and properly made prior to such
expiration shall be subject to indemnification hereunder notwithstanding any
subsequent expiration.

        9.04  This Agreement (which terms, as used in this Agreement, includes
the Schedules and Exhibits referred to herein) constitutes the entire agreement
among the parties pertaining to the subject matter hereof and supersedes all
prior and contemporaneous agreements, understandings, negotiations and
discussions, whether oral or written, of the parties, and there are no
warranties, representations or other agreements between the parties in
connection with the subject matter hereof except as set forth specifically
herein.  No amendment, supplement, modification, waiver or termination of this
Agreement shall be implied or be binding (including, without limitation, any
alleged waiver based on a party's knowledge of a breach or inaccuracy in any
representation or warranty contained herein) unless in writing and signed by the
party against which such amendment, supplement, modification, waiver or
termination is asserted.  No waiver of a provision of this Agreement shall be
deemed or shall constitute a waiver of any other provision hereof (whether or
not  similar), nor shall such waiver constitute a continuing waiver unless
otherwise expressly therein provided.

        9.05  All of the terms and provisions of this Agreement by or for the
benefit of the parties shall be binding upon and inure to the benefit of their
successors, assigns, heirs and personal representatives.  The rights and
obligations provided by this Agreement shall not be assignable, except by TriMas
(without discharge of its obligations hereunder) to a subsidiary or affiliate or
a successor to its business and, except as expressly provided herein, nothing
herein is intended to confer upon any person other than the parties and their
successors, any rights or remedies under or by reason of this Agreement.

Agreement shall be in form and content reasonably satisfactory to the counsel
for the party receiving such instrument or document.  Each Exhibit shall be
identified by a cover page and initialed on each page for purposes of
identification on behalf of Masco by an officer or counsel for Masco.  TriMas'
authorized representative or counsel shall likewise initial each page thereof
solely for purposes of identification and to acknowledge receipt thereof.  Each
Exhibit shall be deemed an integral part of this Agreement.

        9.07  This Agreement my be executed simultaneously in two or

        9.09  In order to preserve for TriMas the corporate opportunity of the
business of each of the Groups, Masco agrees that, for a period of ten years
following the Closing, neither Masco nor any subsidiary of Masco will, directly
or indirectly, engage in any Business Activity in respect of the Products, as
such terms are hereinafter defined (other than on behalf of TriMas or any of its
subsidiaries and other than as a result of any activities engaged in by Masco
Industries, Inc. or any of its subsidiaries) whether such engagement is as a
proprietor, partner, or investor (other 

                                     -42-


<PAGE>   43

than as a holder of less than 10% of the outstanding capital stock of a
publicly traded corporation) in the respective geographic areas in which the
products or services of the Groups have been distributed or provided during the
two year period prior to the Closing; provided, however, that the foregoing
shall in no way restrict Masco or any of its subsidiaries or any entity in which
Masco or any of its subsidiaries has a investment from investing in and
thereafter owning or operating any such entity whose annual revenues for the
complete fiscal year immediately prior to such investment, relating to the
Business Activities in respect of the Products, do not exceed 15% of the total
revenues of such entity for such year.  For purposes of this Section 9.09,
"subsidiary of Masco" is defined as any company (i) over 50% of the common stock
of which is owned by Masco, and (ii) a majority of the directors of which can be
elected by Masco.  "Business Activity" is defined as designing, developing,
manufacturing, selling, marketing or servicing Products.  "Products" are defined
as weight-distributing and weight-carrying hitches, custom hitch receivers, sway
control devices and towing accessories; marine trailer, automatic brake and worm
gear winches, trailer jacks for marine, industrial and agricultural
applications, couplers and trailer accessories, outboard motor brackets, boat
hooks, boarding ladders, boat cover poles, boat fender holders, paddles,
trolling motor connecting rod assemblies, marine radar reflectors and radar
scanner platforms and propeller locks and rudders; and pressure sensitive tapes
and coatings and facing for commercial and industrial insulation.  It is
expressly understood and agreed that although Masco and TriMas consider the
restrictions contained in this Section 9.09 to be reasonable for the purpose of
preserving for TriMas the corporate opportunity of each of the Groups, if a
final judicial determination is made by a court having jurisdiction that the
time or territory or any other restriction contained in this Section 9.09 is an
unenforceable restriction on the activities of Masco or its subsidiaries, the
provisions of this Section 9.09 shall not be rendered void but shall be deemed
amended to apply as to such maximum time and territory and to such other extent
as such court may judicially determine or indicate to be reasonable. 
Alternatively, if the court referred to above finds that any restriction
contained in this Section 9.09 is unenforceable, and such restriction cannot be
amended so as to make it enforceable, such finding shall not affect the
enforceability of any of the other restrictions contained therein.

                                     -43-

        9.10  For purposes of this Agreement, "knowledge of Masco" or phrases of
similar import will be deemed to include the knowledge of the officers,
directors and other key employees of Masco and each of the Groups.

        9.11  TriMas agrees that it will not, with respect to any of the Groups,
effect any "plant closing" or "mass layoff" as defined by Section 1 of the
Worker Adjustment and Retraining Notification Act, within 60 days after the date
of Closing.

        9.12  Except with respect to Compac, immediately after the Closing,
TriMas will cause each of the Groups to use all reasonable efforts to cause the
products of each of the Groups to be identified as manufactured after the date
of Closing.

        9.13  TriMas and Masco each agree with the other that the original sales
and accounting records of each of the Groups to be delivered to or retained by a
party pursuant to the terms hereof shall be retained by such party for a period
of five years after the Closing and that such party shall afford to the other
reasonable access thereto as may be necessary for purposes of preparing tax
returns, financial statements or for such other purposes as such other party may
reasonably request.

        9.14  After the Closing, each of the parties will execute and deliver
from time to time at the request of the other party all such other instruments
as are necessary or appropriate to evidence or effectuate the transactions
contemplated by this Agreement.

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

                    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
("MSX").

        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.
