each year. The first such payment will be made on December 15, 2002. We have
the option to redeem all or a portion of the exchange notes at any time at the
redemption prices set forth in this prospectus. Prior to June 15, 2005, we may
redeem up to 35% of the exchange notes at 111% of the principal amount, plus
accrued and unpaid interest, with the net proceeds of certain equity issuances,
provided at least 65% of the original aggregate principal amount of the
exchange notes remains outstanding immediately after such redemption. The
exchange notes will be issued only in denominations of $1,000 and integral
multiples of $1,000.

     The notes will be guaranteed by each of our current and future domestic
subsidiaries that is a guarantor or direct borrower under our credit facility.
The exchange notes and the guarantees will rank junior to all of our and the
guarantors' existing and future senior indebtedness and secured indebtedness,

                                  THE COMPANY

     We are a leading supplier of highly engineered metal components for the
global light vehicle market. Through a combination of capabilities in design,
engineering, fabrication, machining and assembly, we supply components and
modular systems used in vehicle transmission, engine and chassis applications.
Our products are sold primarily to both North American and international light
vehicle original equipment manufacturers, or OEMs, and Tier I component
assemblers and provide content for approximately 95% of the top 40 NAFTA light
vehicles produced in 2001. Tier I component assemblers are direct suppliers to
OEMs of integrated modules, such as a complete engine assembly or drivetrain
assembly. Our metal forming processes include cold, warm and hot forging,
forged and conventional powder metal, tubular fabrications and
precision-aluminum die castings. In addition, we perform design, engineering,
machining, finishing and assembly functions. We have approximately 8,500
employees and more than 40 owned or leased manufacturing facilities worldwide.

     In North America, we have leading market shares in several of our
products. We are the largest independent forging company, the second largest
independent "machining and assembly" supplier, and one of the largest powder
metal manufacturers for light vehicle applications. We believe our scale and
combined capabilities represent a significant competitive advantage over our
competitors, many of which are smaller and do not have the ability to combine
metal forming with machining and sub-assembly capabilities. We serve over 300
customers, including BMW, Dana, DaimlerChrysler, Ford, General Motors, Delphi,
Honda, New Venture Gear, Nissan, Renault, Toyota, TRW and Visteon.

     We have organized our businesses into three principal product groups:
Transmission Products, Engine Products and Chassis Products.

     o TRANSMISSION PRODUCTS. We are a leading independent manufacturer of
       components, modules and systems, including precision shafts, hydraulic
       controls, hot and cold forgings and integrated program management used in
       a broad range of transmission applications. We believe that we have
       leading market shares in several product areas, including the number one
       position in transmission and transfer case shafts, transmission valve
       bodies, cold extrusion and Hatebur hot forgings. In 2001, our
       Transmission Products group generated sales of approximately $798 million
       (before eliminating intercompany sales).

     o ENGINE PRODUCTS. We are a leading supplier of a broad range of engine
       components, modules and systems. The group manufactures sintered metal,
       powder metal, forged and tubular fabricated products used for a variety
       of applications, including balance shaft modules and front cover
       assemblies. We have leading market shares in powder metal connecting rods
       and several categories of forgings. In 2001, the sales of the Engine
       Products group were $460 million (before eliminating intercompany sales).

     o CHASSIS PRODUCTS. We are a leading supplier of components, modules and
       systems used in a variety of engineered chassis applications, including
       fittings, wheel-ends, axle shafts, knuckles, and mini-corner assemblies.
       This group utilizes a variety of processes including hot, warm and

                                       1





       cold forging, powder metal forging and machinery and assembly. We apply
       full-service integrated machining and assembly capabilities to an array
       of chassis components. In 2001, the sales of the Chassis Products group
       were $155 million (before eliminating intercompany sales).


MARKET OPPORTUNITY AND GROWTH STRATEGY

     In order to reduce costs and consolidate volume with full scale suppliers,
we believe OEMs and Tier I suppliers will increasingly seek to outsource the
design, manufacture and assembly of fully integrated, modular assemblies of
metal parts in engine, transmission and chassis. We believe that the following
favorable market factors will drive the domestic OEM's desire to continue
outsourcing:

     o emissions, fuel economy and customer preferences are driving the design
       of a new generation of components for engine, transmission and chassis
       applications to increase efficiency and performance and reduce weight;

     o OEMs are consolidating their supply base among global, full service
       suppliers capable of meeting their needs uniformly across their
       geographic production base; and

     o in many cases, full scale suppliers have lower production costs than
       OEMs and are able to provide significant cost reduction opportunities.

     Our strategy is to become one of the leading suppliers of high-quality,
low-cost metal formed components, assemblies and modules to the global light
vehicle industry. Key elements of our strategy include the following:

     o FOCUS ON FULL-SERVICE, INTEGRATED SUPPLY OPPORTUNITIES. By offering a
       full complement of metal solutions, we believe we provide OEMs with
       "one-stop" shopping to optimize weight, cost, stress, durability, fatigue
       resistance and other metal component attributes of products. Our
       capabilities in engineering, design, machining and assembly position us
       to capture a greater share of the "value chain" and deliver to customers
       finished assemblies and modules rather than independent parts. Currently,
       OEMs satisfy a significant portion of their metal forming and assembly
       requirements with in-house production and assembly of purchased
       components. We believe that, as OEMs seek to outsource the design and
       manufacture of parts, they will choose suppliers with expertise in
       multiple metal-forming technologies and the ability to design, engineer
       and assemble components rather than supply independent parts. We intend
       to enhance our strengths in forged steel, powder metal and
       precision-aluminum die cast components by adding metal and process
       capabilities in aluminum foundry and magnesium die casting.

     o INCREASE CONTENT PER VEHICLE. We are aggressively pursuing new business
       opportunities to supply a larger portion of value-added content utilizing
       our integrated capabilities. These opportunities can result in
       significant increases in content per vehicle on related programs. For
       example, we were recently awarded a contract by a leading North American
       OEM to manufacture clutch modules that incorporates our metal-forming,
       aluminum die casting, product development and machining and assembly
       capabilities. We have received various new business awards from our
       domestic and transplant customers across many of our product categories.
       We have been awarded net new business that is projected, based on our
       customers' production forecasts, to generate additional cumulative sales
       of approximately $1.9 billion from 2002 through 2006. In 2001, our
       content per vehicle in North America was approximately $70 and we expect
       to materially increase our content per vehicle as a result of new
       business awards that we are pursuing.

     o LEVERAGE OUR ENGINEERING, DESIGN AND INFORMATION TECHNOLOGY
       CAPABILITIES. We believe that in order to effectively develop total metal
       component and assembly solutions it is necessary to integrate research,
       development and design elements with product fabrication, machining,
       finishing and assembly. We believe that our larger scale and broader
       product line relative to


                                       2




       most of our competitors will enable us to more efficiently invest in
       engineering, design and information technology and develop a significant
       competitive advantage. For example, we recently designed and developed a
       front engine module that integrates multiple components into one fully
       tested end item which increased the products' performance and durability
       while reducing noise/vibration effects and overall system costs.

     o CONTINUE TO PURSUE COST SAVINGS OPPORTUNITIES AND OPERATING
       SYNERGIES. We have pursued, and will continue to pursue, cost savings
       that enhance our competitive position in serving OEMs and Tier I
       suppliers. In 2001, we successfully completed cost savings programs
       involving a consolidation of headquarter functions and the elimination of
       an outsourcing agreement with our former controlling shareholder to
       reduce annual corporate overhead expenses by 25%, the closure and
       consolidation of manufacturing and distribution facilities and an
       aggressive cash management program. In addition, we have invested in and
       are implementing a comprehensive shared services platform for a range of
       overhead functions including finance, procurement and human resources. We
       believe the shared services program will improve management information
       and result in further cost savings in the future. We believe we have
       additional opportunities to improve our margins as we achieve operating
       synergies with increased volumes and continue to vertically integrate our
       machining and assembly capacity with our metal forming abilities. We
       intend to pursue opportunities to improve our sourcing costs for key
       commodity inputs, such as primary and secondary scrap, hot bar and rod
       and other key raw material components.

     o PURSUE STRATEGIC COMBINATIONS AND GLOBAL EXPANSION OPPORTUNITIES. We
       plan to continue to pursue acquisitions that strategically expand our
       metal and process capabilities in aluminum foundry and magnesium die
       casting and contribute to our geographic diversity and market share.
       Global expansion is an important component of our growth strategy since a
       significant portion of the global market for engineered metal parts is
       outside of North America. Furthermore, as OEMs continue to consolidate
       their supply base, they are seeking global suppliers that can provide
       seamless product delivery across geographic production regions. We
       believe our size, strong market shares in North America and customer
       relationships strongly position us to capitalize on this trend.

     In November 2000, we were acquired by an investor group led by Heartland
Industrial Partners, L.P. and Credit Suisse First Boston Equity Partners, L.P.
Subsequent to this transaction, we completed two acquisitions to leverage our
leading market position with additional products and capabilities. In December
2000, we acquired Simpson Industries, Inc., a leader in design, machining and
sub-assembly of automotive components. In June 2001, we acquired Global Metal
Technologies, Inc., or GMTI, a leading provider of precision-aluminum die
castings for engine and driveline applications. The Issuer is a holding company
and substantially all of our operations are conducted through our subsidiaries.


                              RECENT DEVELOPMENTS

     TriMas Divestiture. On June 6, 2002 our former wholly owned subsidiary
TriMas Corporation, or TriMas, issued approximaley 66% of its fully diluted
common equity to Heartland Industrial Partners, L.P. and other investors. Our
shareholders (other than Heartland) that are parties to our shareholders
agreement had a right to acquire a proportionate share of such 66% interest.
Accordingly, some of our shareholders exercised their rights and acquired an
aggregate 5% interest in TriMas, reducing Heartland's interest to 61%. We
retained approximately 34% of the fully diluted common equity of TriMas in the
form of common stock and a presently exercisable warrant to purchase shares of
common stock at a nominal exercise price. In connection with the TriMas
divestiture, we received $840 million in consideration in the form of cash and
debt reduction. As a result of the transaction, after payment of expenses, we
repaid approximately $496 million of term debt under our senior credit facility
and reduced our outstanding balances under our receivables facility by
approximately $136 million (of which approximately $86 million related to the
elimination of the TriMas receivables


                                       3




base) and we utilized an additional $205 million in cash to repurchase, either
at prevailing market prices or pursuant to a tender offer described below, a
portion of our outstanding 4.5% convertible subordinated debentures due 2003.
For a more complete discussion of the transaction and its ongoing impact upon
us, see "Certain Relationships and Related Party Transactions" and our
Quarterly Report on Form 10-Q for the period ended June 30, 2002, which is
incorporated by reference in this prospectus. The purpose of this divestiture
was to allow us to repay some of our debt maturing in 2003, defer some of our
credit facility amortization by repaying term debt with the proceeds in forward
order of maturity, enhance our liquidity and allow us to focus on our core
metal-forming businesses while retaining an interest in TriMas.

     Goodwill and Other Intangible Assets. Effective January 1, 2002, we
adopted Statement of Financial Accounting Standards, or SFAS, No. 142,
"Goodwill and Other Intangible Assets" and ceased amortizing goodwill. At June
30, 2002, our unamortized balance was approximately $522 million. Our step 1
test as required by SFAS No. 142 indicated a carrying value in excess of fair
value relating to the TriMas reporting units at January 1, 2002. As discussed
in our June 30, 2002 Form 10-Q filing, we completed our assessment for the
Automotive Group which indicated that the fair value of these units exceed
their corresponding carrying value. Fair value was determined based upon the
discounted cash flows of the reporting units. Subsequent to filing the June 30,
2002 Form 10-Q, we completed our transitional impairment test needed to measure
the amount of any goodwill impairment for our former TriMas subsidiary. A
non-cash, after tax charge of $36.6 million as of January 1, 2002, related to
the industrial fasteners business which was divested by Metaldyne in June 2002,
was taken. Sales, operating profits and cash flows for this TriMas owned
business were lower than expected beginning in the first quarter of 2001, due
to the overall economic downturn and cyclical declines in certain markets for
industrial fastener products. Based on that trend, the earnings and cash flow
forecasts for the next five years indicated the goodwill impairment loss.
Consistent with the requirements of SFAS 142, as of January 1, 2002, we will
recognize this impairment charge as the cumulative effect of change in
accounting principle during the nine months ended September 29, 2002.

     This effect of adoption of SFAS 142 on our condensed results of operations
for the six months ended June 30, 2002 was as follows:





                                                                      AS                      AS

     Tender Offer for Debentures. On August 21, 2002, we completed an offer to
purchase up to, and subsequently accepted for purchase, $78.2 million aggregate
principal amount of our outstanding 4 1/2% convertible subordinated debentures
due 2003. After giving effect to the purchase, there is $100.0 million
aggregate principal amount of debentures outstanding. We utilized cash
specifically retained from the TriMas divestiture to fund the debenture
purchase. In addition, we paid approximately $1.1 million in accrued interest,
fees and expenses in connection with the tender offer. As a result of our
November 2000 acquisition, the convertible subordinated debentures are no
longer convertible into our common stock.

                         SUMMARY OF THE EXCHANGE NOTES

     The summary below describes the principal terms of the exchange notes. The
form and terms of the exchange notes are substantially identical to the form
and term of the original notes, except that we will register the exchange notes
under the Securities Act, and therefore, the exchange notes will not bear
legends restricting their transfer. Certain of the terms and conditions
described below are subject to important limitations and exceptions. The
"Description of Notes" section of this prospectus contains a more detailed
description of the terms and conditions of the exchange notes.


Issuer......................   Metaldyne Corporation.


Securities Offered..........   $250,000,000 in aggregate principal amount of
                               11% Senior Subordinated Notes due 2012.

Guarantees..................   All payments on the exchange notes, including
                               principal and interest, will be jointly and
                               severally guaranteed on a senior subordinated
                               unsecured basis by each of our existing and
                               future domestic restricted subsidiaries that is a
                               guarantor or direct borrower under our credit
                               facility.


Ranking.....................   The exchange notes and the guarantees will
                               rank:

                               o junior to all of our and the guarantors'
                                 existing and future senior indebtedness and
                                 secured indebtedness, including any
                                 borrowings under our credit facility;

                               o equally with any of our and the guarantors'
                                 future unsecured senior subordinated
                                 indebtedness, including trade payables;

                               o senior to any of our and the guarantors'
                                 future indebtedness that is expressly
                                 subordinated in right of payment to the
                                 notes; and

                               o effectively junior to all of the liabilities
                                 of our subsidiaries, that have not guaranteed
                                 the notes.

                               At June 30, 2002, the exchange notes and the
                               guarantees would have ranked junior to
                               approximately $400.0 million of senior
                               indebtedness. In addition, our non-guarantor
                               subsidiaries would have had approximately $13.6
                               million of indebtedness, excluding intercompany
                               obligations of our non-guarantor subsidiaries,
                               plus other liabilities, including trade
                               payables.

                               At June 30, 2002, on a pro forma basis after
                               giving effect to the repurchase of $78.2 million
                               aggregate principal amount of our outstanding
                               4.5% convertible subordinated debentures due
                               2003 in August 2002, the obligations of the
                               Issuer and our direct wholly owned subsidiary,
                               Metaldyne Company


                                       5



                               LLC, in respect of the notes and the guarantees
                               would have ranked pari passu with $100.0 million
                               principal amount of our convertible subordinated
                               debentures, but the subordinated debentures are
                               not obligations of any of the other guarantors
                               and, therefore, guarantees in respect of the
                               exchange notes rank structurally senior to the
                               convertible subordinated debentures.


Optional Redemption.........   We may redeem the exchange notes, in whole or
                               in part, at the redemption prices set forth in
                               this prospectus plus accrued and unpaid interest,
                               if any, to the date of redemption. In addition,
                               at any time prior to June 15, 2005, we may redeem
                               up to 35% of the exchange notes at 111% of the
                               principal amount, plus accrued and unpaid
                               interest, with the net proceeds of certain equity
                               issuances, provided at least 65% of the original
                               aggregate principal amount of the exchange notes
                               remains outstanding immediately after such
                               redemption.


Change of Control...........   Upon the occurrence of a change of control, we
                               will be required to make an offer to purchase
                               each holder's exchange notes at a price equal to
                               101% of the principal amount, plus accrued and
                               unpaid interest, if any, to the date of purchase.


Restrictive Covenants.......   The exchange notes will be issued under an
                               indenture with The Bank of New York, as trustee.
                               The indenture governing the exchange notes will
                               limit the ability of the Issuer and its
                               restricted subsidiaries to, among other things:

                               o incur or guarantee additional indebtedness;

                               o pay dividends or make other distributions or
                                 repurchase or redeem our stock;

                               o make investments;

                               o sell assets;

                               o create liens;

                               o enter into agreements restricting our
                                 restricted subsidiaries' ability to pay
                                 dividends;

                               o enter into transactions with affiliates; and

                               o consolidate, merge or sell all or
                                 substantially all of our assets.

                               These covenants are subject to important
                               exceptions and qualifications, which are
                               described under the heading "Description of
                               Notes" in this prospectus.

                        SUMMARY HISTORICAL FINANCIAL DATA


     The following table sets forth our summary historical financial data for
the five years ended December 31, 2001 and the six months ended June 30, 2001
and 2002. The financial data for the fiscal years ended December 31, 1999, 2000
and 2001 have been derived from our audited consolidated financial statements
and the notes to those financial statements, which have been audited by
PricewaterhouseCoopers LLP, independent accountants. The financial data for the
fiscal year ended December 31, 1997 and 1998 have been derived from our audited
consolidated financial statements not included in this prospectus. The selected
information for the six months ended June 30, 2001 and 2002 has been derived
from our unaudited consolidated financial statements, which, in the opinion of
management, include all adjustments, which are normal and recurring in nature
necessary for the fair presentation of that data for such periods.


     On November 28, 2000, Metaldyne was acquired by an investor group led by
Heartland Industrial Partners, L.P. The pre-acquisition basis of accounting for
periods prior to November 28, 2000 is reflected on the historical basis of
accounting and all periods subsequent to November 28, 2000 are reflected on a
purchase accounting basis and are therefore not comparable. In reviewing the
following information, it should be noted that there is or will be significant
non-compatibility across recent periods or with future periods. This
non-compatibility arises because in December 2000 we acquired Simpson
Industries, Inc., a leader in design, machining and sub-assembly of automotive
components, beginning in January 2001, our results include the results for
Global Metal Technologies, Inc., or GMTI, a leading provider of
precision-aluminum die castings for engine and driveline applications, in
January 1998 we acquired TriMas and effective January 1, 2002 we adopted SFAS
142 and stopped the amortization of goodwill. In June 2002, we divested
ourselves of 66% of our equity interests in TriMas.

                                  RISK FACTORS

     You should carefully consider each of the risks described below, together
with all of the other information contained in this prospectus, before deciding
to invest in the notes.


RISKS RELATED TO OUR BUSINESS

THE INDUSTRIES IN WHICH WE OPERATE DEPEND UPON GENERAL ECONOMIC CONDITIONS AND
ARE HIGHLY CYCLICAL.

     Our financial performance depends, in large part, on conditions in the
cyclical markets that we serve, such as the automotive and light-duty truck
industries, and on the U.S. and global economies generally. Our sales to OEMs
and Tier I and Tier II suppliers in the automotive and light- and heavy-duty
truck industries accounted for virtually all of our net sales in 2001. Tier II
suppliers are direct suppliers to both OEMs and Tier I suppliers of integrated
modules, such as engine and suspension modules and brake corner modules. Demand
for new vehicles fluctuates in response to overall economic conditions and is
particularly sensitive to changes in interest rate levels, consumer confidence
and fuel costs. In our largest market, the North American automotive market,
reported results from our customers in 2001 reflected lower sales volumes and
lower prices for vehicles than in 2000. This is reflected in our lower sales
and margins in 2001. The September 11, 2001 terrorist attacks, recession and
other recent developments adversely affected confidence throughout the U.S. and
much of the world. These developments exacerbated the uncertainty in our
markets and their future impact on us is difficult to predict. Any sustained
weakness in demand or continued downturn or uncertainty in the economy
generally would negatively impact our financial results.

     Our sales are also impacted by retail inventory levels and our customers'
production schedules. In 2001, our OEM customers significantly reduced their
production and inventory levels and reduced their orders from us due to the
uncertain economic environment. In this environment, we cannot predict future
production rates and inventory levels and the sustainability of any recovery.
In addition, we have experienced historical sales declines during OEMs'
scheduled shutdowns, which usually occur during the third calendar quarter.
Continued uncertainty and other unexpected fluctuations may have a material
adverse effect upon us.

OUR BASE OF CUSTOMERS IS CONCENTRATED AND THE LOSS OF BUSINESS FROM A MAJOR
CUSTOMER, THE DISCONTINUANCE OF PARTICULAR VEHICLE MODELS OR A CHANGE IN AUTO
CONSUMER PREFERENCES OR REGULATIONS COULD MATERIALLY ADVERSELY EFFECT US.

     Because of the relative importance of our largest customers and the high
degree of concentration of OEMs in the North American automotive industry, our
business is exposed to a high degree of risk related to customer concentration.
While our three largest OEM customers accounted for approximately 39.9% of our
net sales in 2001, our customers include Tier I and Tier II suppliers, such as
New Venture Gear, Delphi, Dana and Visteon, that serve the large OEMs.
Accordingly, while Ford, General Motors and DaimlerChrysler directly accounted
for approximately 16.6%, 12.9% and 10.4%, respectively, of our net sales in
2001, we have a material indirect exposure to these and other OEMs due to our
significant Tier I and Tier II supplier base. New Venture Gear (a joint venture
of General Motors and DaimlerChrysler) represented approximately 11.7% of our
net sales in 2001, for example. A loss of significant business from, or adverse
performance by, any of these OEM customers or of our significant Tier I and
Tier II suppliers serving these OEM customers would be harmful to us and make
it more difficult for us to meet our obligations in respect of the notes.
Further deterioration of the market share held by the three largest domestic
automakers could also impact our revenues. Production cuts at these OEMs could
also adversely impact our sales to Tier I and Tier II suppliers. The contracts
we have entered into with most of our customers provide for supplying the
customers' annual requirements against a blanket purchase order for certain
vehicle models, rather than for manufacturing a specific quantity of products.
Most of these purchase orders are terminable at will by the customers.
Therefore, the loss of a contract or a significant decrease in demand for
certain key models or group of related models sold by any of our major
customers could have a material adverse effect on us.


                                       9



     In addition, our sales are influenced by customer preferences and
regulatory changes. A significant portion of our sales have been derived from
products used in sports utility vehicles, or SUVs, and light trucks, which has
been favorable due to their high metal content. Until recently, these vehicles
had experienced positive sales trends for several years. There can be no
assurance that sales of these vehicles will not continue to decline. In
addition, government regulations, including those relating to fuel economy,
could impact vehicle content and volume and, accordingly, have a material
adverse impact on us.

WE INTEND TO ACTIVELY PURSUE ACQUISITIONS AND/OR JOINT VENTURES BUT WE MAY NOT
BE ABLE TO IDENTIFY ATTRACTIVE ACQUISITION AND/OR JOINT VENTURE CANDIDATES,
SUCCESSFULLY INTEGRATE OUR ACQUIRED OPERATIONS OR REALIZE THE INTENDED BENEFITS
OF OUR ACQUISITIONS AND/OR JOINT VENTURES.

     Our strategy is to become a full-service, integrated global provider of
engineered-metal products. This will necessitate further acquisition and/or
joint venture activity. We continually evaluate potential acquisitions and
joint ventures and are engaged in discussions with material acquisition and
joint venture candidates. On July 18, 2002, we and DaimlerChrysler Corporation
announced a non-binding letter of intent to form a joint venture to operate the
new Castle Machining Forge facility presently owned by DaimlerChrysler in New
Castle, Indiana. All of our present discussions are preliminary and there can
be no assurance that suitable acquisition candidates will be identified and
acquired in the future, that the financing or necessary consents for any such
acquisitions will be available on satisfactory terms or that we will be able to
accomplish our strategic objectives in making any such acquisition. Nor can we
assure you that our full metal services strategies will be successfully
received by customers or achieve their intended benefits. Acquisitions are
often undertaken to improve the operating results of either or both of the
acquirer and the acquired company, and we cannot assure you that we will be
successful in this regard or that the expenses that we may incur to implement
cost savings plans will not be excessive relative to the anticipated benefits.
We will encounter various risks in acquiring other companies, including the
possible inability to integrate successfully an acquired business into our
operations and unanticipated problems or liabilities, whether or not known at
the time of acquisition, some or all of which could materially and adversely
affect us. We could incur additional indebtedness in connection with our
acquisition strategy and increase our leverage. We expect to acquire companies
and operations in geographic markets in which we do not currently operate.
Acquisitions outside of North America will present unique structuring,
integration, legal, operating and cultural challenges and difficulties and will
increase our exposure to risks generally attendant to international operations.


IF WE ARE UNABLE TO MEET FUTURE CAPITAL REQUIREMENTS, OUR BUSINESS MAY BE
ADVERSELY AFFECTED.

     We operate in a capital intensive industry. We have made substantial
capital investments from 1996 through 2001 to, among other things, maintain and
upgrade our facilities and enhance our production processes. This level of
capital expenditures was needed to:

     o increase production capacity;

     o improve productivity;

     o satisfy customer requirements; and

     o upgrade selected facilities to meet competitive requirements.

     We have planned capital expenditures of up to approximately $116 million
in 2002. In addition, as we expand our book of business, we may have to incur
other significant expenditures to prepare for and manufacture these products.
We believe that we will be able to fund these expenditures through cash flow
from operations, borrowings under our credit facility and sales of receivables
under our receivables facility. Our credit facility contains limitations which
could affect our ability to fund our capital expenditures and other needs. We
cannot assure you that we will have adequate funds to make all capital
expenditures, when required, or that the amount of future capital expenditures
will not be materially in excess of our anticipated expenditures. If we are
unable to make necessary capital


                                       10



expenditures, our business will be adversely affected. See the "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources" section of our Annual Report on
Form 10-K and Quarterly Reports on Form 10-Q incorporated by reference in this
prospectus.

INCREASES IN OUR RAW MATERIAL OR ENERGY COSTS OR THE LOSS OF A SUBSTANTIAL
NUMBER OF OUR SUPPLIERS COULD NEGATIVELY AFFECT OUR FINANCIAL HEALTH.

     Generally, our raw materials requirements are obtainable from various
sources and in the desired quantities. While we currently maintain alternative
sources for raw materials, our businesses are subject to the risk of price
fluctuations and periodic delays in the delivery of certain raw materials,
component parts and specialty fasteners. Under two- to five-year supply
contracts for special bar quality steel, we have established the prices at
which we will purchase much of our steel requirements. We may not be able to
renegotiate future prices under those contracts at prices favorable to us,
depending on industry conditions. The domestic steel industry has experienced
substantial financial instability due to numerous factors, including energy
costs and the effect of foreign competition. In response to this instability,
tariffs on imported steel were imposed by the U.S. government in March 2002. As
a result, steel prices have begun to rise and we expect to experience increased
steel prices in 2003 when our current contracts expire. See the
"Business--Materials and Supply Arrangements" section of our Annual Report on
Form 10-K incorporated by reference in this prospectus. In addition, a failure
by our suppliers to continue to supply us with certain raw materials or
component parts on commercially reasonable terms, or at all, would have a
material adverse effect on us. Our energy costs are a substantial element of
our cost structure. To the extent there are energy supply disruptions or
material fluctuations in energy costs, our margins could be materially
adversely impacted.

RECENT TRENDS AMONG OUR CUSTOMERS WILL INCREASE COMPETITIVE PRESSURES IN OUR
BUSINESSES.

     The markets for our products are highly competitive. Our competitors
include driveline component manufacturing facilities of existing OEMs, as well
as independent domestic and international suppliers. Certain competitors of our
businesses are large companies that have greater financial resources than us.
At times, we may be in a position of competing with some of our own customers,
such as Tier I suppliers which could have adverse consequences. We believe that
the principal competitive factors for all of our businesses are product quality
and conformity to customer specifications, design and engineering capabilities,
product development, timeliness of delivery and price. In addition, our
competitors may develop products that are superior to our products or may adapt
more quickly than us to new technologies or evolving customer requirements.
Recent trends by our customers in many of our markets to limit their number of
outside vendors have resulted in increased competition as many manufacturers
and distributors have reduced prices to compete more effectively. In addition,
financial and operating difficulties experienced by our major customers may
result in further pricing pressures. We expect competitive pressures in our
markets to remain strong. Such pressures arise from existing competitors, other
companies that may enter our existing or future markets and, in certain cases,
our customers, which may decide to internalize production of certain items sold
by us. There can be no assurance that we will be able to compete successfully
with our existing competitors or with new competitors. Failure to compete
successfully could have a material adverse effect on us.

OUR PRODUCTS ARE SUBJECT TO CHANGING TECHNOLOGY, WHICH COULD PLACE US AT A
COMPETITIVE DISADVANTAGE RELATIVE TO ALTERNATIVE PRODUCTS INTRODUCED BY
COMPETITORS.

     We believe that our customers rigorously evaluate their suppliers on the
basis of product quality, price competitiveness, technical expertise and
development capability, new product innovation, reliability and timeliness of
delivery, product design capability, manufacturing expertise, operational
flexibility, customer service and overall management. Our success will depend
on our ability to continue to meet our customers' changing specifications with
respect to these criteria. We may, therefore, require significant ongoing and
recurring additional capital expenditures and investment in research and
development, manufacturing and other areas to remain competitive. We cannot
assure


                                       11



you that we will be able to achieve the technological advances or introduce new
products that may be necessary to remain competitive within our business. In
addition, any decreasing demand by our customers in favor of plastics could
have a material adverse effect. Further, we cannot assure you that any
technology development by us can be adequately protected such that we can
maintain a sustainable competitive advantage.

WE DEPEND ON THE SERVICES OF KEY INDIVIDUALS AND RELATIONSHIPS, THE LOSS OF
WHICH WOULD MATERIALLY HARM US.

     Our success will depend, in part, on the efforts of our executive officers
and other key employees. In addition, our future success will depend on, among
other factors, our ability to attract and retain other qualified personnel. The
loss of the services of any of our key employees or the failure to attract or
retain employees could have a material adverse effect on us. In addition, our
largest stockholder, Heartland, provides us with valuable strategic,
operational and financial support, the loss of which could materially adversely
affect us.

WE MAY BE SUBJECT TO WORK STOPPAGES AT OUR FACILITIES OR THOSE OF OUR PRINCIPAL
CUSTOMERS, WHICH COULD SERIOUSLY IMPACT THE PROFITABILITY OF OUR BUSINESS.

     As of June 30, 2002, approximately 30% of our work force was unionized,
principally through the United Auto Workers union, or UAW. We experienced a
labor strike at our Fraser, Michigan plant which lasted from July 1997 to June
1998 and involved approximately 140 employees. If our unionized workers were to
engage in a strike, work stoppage or other slowdown in the future, we could
experience a significant disruption of our operations, which could have a
material adverse effect on us. In addition, if a greater percentage of our work
force becomes unionized, our business and financial results could be materially
adversely affected. See the "Business--Employees and Labor Relations" section
of our Annual Report on Form 10-K incorporated by reference in this prospectus.


     Many of our direct or indirect customers have unionized work forces.
Strikes, work stoppages or slowdowns experienced by automotive OEMs or their
suppliers could result in slowdowns or closures of assembly plants where our
products are included in assembled vehicles. For example, over the past four
years, there have been a number of labor strikes against General Motors that
have resulted in work stoppages at General Motors. In addition, organizations
responsible for shipping our customers' products may be impacted by occasional
strikes staged by the Teamsters Union. Any interruption in the delivery of our
customers' products would reduce demand for our products and could have a
material adverse effect on us.

OUR STRATEGY MAY NOT SUCCEED IF ANTICIPATED OUTSOURCING FAILS TO OCCUR DUE TO
UNION CONSIDERATIONS.

     Because of the economic benefits inherent in outsourcing to suppliers and
the costs associated with reversing a decision to purchase products from an
outside supplier, automotive OEMs' commitment to purchasing modules from
outside suppliers, particularly on a "just-in-time" basis, are expected to
increase. However, under the contracts currently in effect in the United States
and Canada between each of Ford, General Motors and DaimlerChrysler with the
UAW and the Canadian Auto Workers, or CAW, in order for any of such automotive
OEMs to obtain components from external sources that it currently produces, it
must first notify the UAW or the CAW of such intention. If the UAW or the CAW
objects to the proposed outsourcing, some agreement will have to be reached
between the UAW or the CAW and the automotive OEM. Factors that will normally
be taken into account by the UAW, the CAW and the automotive OEM include:

     o whether the proposed new supplier is technologically more advanced than
       the automotive OEM;

     o whether the new supplier is unionized;

     o whether cost benefits exist; and

     o whether the automotive OEM will be able to reassign union members whose
       jobs are being displaced to other jobs within the same factories.


                                       12



     In the event that outsourcing does not occur for any reason, it may have a
material adverse effect on us.

A GROWING PORTION OF OUR REVENUE MAY BE DERIVED FROM INTERNATIONAL SOURCES,
WHICH EXPOSES US TO CERTAIN RISKS.

     Approximately 19% of our sales in 2001 were derived from sales by our
subsidiaries located outside of the United States. As part of our business
strategy, we intend to expand our international operations through internal
growth and acquisitions. Significant market share has shifted to foreign OEMs
in the SUV and light truck platforms where we derive a significant portion of
our sales. Sales outside of the United States, particularly sales to emerging
markets, are subject to other various risks including governmental embargoes or
foreign trade restrictions such as antidumping duties, changes in U.S. and
foreign governmental regulations, the difficulty of enforcing agreements and
collecting receivables through certain foreign local systems, foreign customers
may have longer payment cycles than customers in the U.S., more expansive legal
rights of foreign unions, tariffs and other trade barriers, the potential for
nationalization of enterprises, foreign exchange risk and other political,
economic and social instability. In addition, there are tax inefficiencies in
repatriating cash flow from non-U.S. subsidiaries. To the extent such
repatriation is necessary for us to meet our debt service or other obligations,
this will adversely affect us.

WE MAY INCUR MATERIAL LOSSES AND COSTS AS A RESULT OF PRODUCT LIABILITY AND
WARRANTY CLAIMS THAT MAY BE BROUGHT AGAINST US.

     We face an inherent business risk of exposure to product liability claims
in the event that the use of our current and formerly manufactured or sold
products results, or is alleged to result, in bodily injury and/or property
damage. We cannot assure you that we will not experience any material product
liability losses in the future or that we will not incur significant costs to
defend such claims. We cannot assure you that our product liability insurance
coverage will be adequate for any liabilities that may ultimately be incurred
or that it will continue to be available on terms acceptable to us. In
addition, if any of our products are or are alleged to be defective, we may be
required to participate in a government-required or manufacturer-instituted
recall involving such products. In the automotive industry, each vehicle
manufacturer has its own policy regarding product recalls and other product
liability actions relating to its suppliers. However, as suppliers become more
integrally involved in the vehicle design process and assume more of the
vehicle assembly functions, vehicle manufacturers are increasingly looking to
their suppliers for contribution when faced with product liability claims. A
successful claim brought against us in excess of our available insurance
coverage or a requirement to participate in a product recall may have a
materially adverse effect on our business. In the ordinary course of our
business, contractual disputes over warranties can also arise. In the past five
years or more, we have not been required to make any material payments in
respect of warranty claims. In addition, we cannot assure you that claims will
not be asserted against us with respect to former businesses disposed of by us,
whether or not we are legally responsible or entitled to contractual
indemnification. For example, in June 2002, we divested a significant interest
in TriMas. Certain of TriMas' subsidiaries have historical contingent and other
liabilities, including liabilities associated with their former manufacture of
asbestos containing gaskets, for which we are indemnified. In the event of
financial difficulty at one of those companies or otherwise, we cannot assure
you that claims will not be made against us or that TriMas will be in a
position to meet its indemnification obligations.

OUR BUSINESS MAY BE MATERIALLY AND ADVERSELY AFFECTED BY COMPLIANCE OBLIGATIONS
AND LIABILITIES UNDER ENVIRONMENTAL LAWS AND REGULATIONS.

     We are subject to federal, state, local and foreign environmental, and
health and safety, laws and regulations that:

     o affect ongoing operations and may increase capital costs and operating
       expenses in order to maintain compliance with such requirements; and

     o impose liability relating to contamination at our facilities, and at
       other locations such as former facilities, facilities where we have sent
       wastes for treatment or disposal, and other


                                       13



      properties to which we (or a company or business for which we are
      responsible) are linked. Such liability may include, for example,
      investigation and clean-up of the contamination, personal injury and
      property damage caused by the contamination, and damages to natural
      resources. Some of these liabilities may be imposed without regard to
      fault, and may also be joint and several (which can result in a liable
      party being held responsible for the entire obligation, even where other
      parties are also liable).

     We are legally or contractually responsible or alleged to be responsible
for the investigation and remediation of contamination at various sites, and
for personal injury or property damages, if any, associated with such
contamination. Our subsidiaries have been named as potentially responsible
parties under the Federal Superfund law or similar state laws in several sites
requiring cleanup related to disposal of wastes we generated. These laws
generally impose liability for costs to investigate and remediate contamination
without regard to fault and under certain circumstances liability may be joint
and several resulting in one responsible party being held responsible for the
entire obligation. Liability may also include damages to natural resources. Our
businesses have incurred and likely will continue to incur expenses to
investigate and clean up existing and former company-owned or leased property.
Additional sites may be identified at which we are a potentially responsible
party under the federal Superfund law or similar state laws. We cannot assure
you that these or other liabilities will not have a material adverse effect
upon us. See the "Business--Environmental Matters" section of our Annual Report
on Form 10-K incorporated by reference in this prospectus.

WE ARE CONTROLLED BY HEARTLAND, WHOSE INTERESTS IN OUR BUSINESS MAY BE DIFFERENT
THAN YOURS.

     Heartland and its affiliates are able to control our affairs in all cases,
except for certain actions specified in a shareholders agreement among
Heartland, Credit Suisse First Boston Equity Partners, L.P. together with its
affiliated funds, or CSFB Private Equity, Masco Corporation, Richard Manoogian
and their various affiliates and certain other investors. Under the
shareholders agreement, holders of approximately 94% of our outstanding shares
of common stock have agreed to vote their shares for directors representing a
majority of our board that have been designated by Heartland. You should
consider that the interests of Heartland, as well as our other owners, will
likely differ from yours in material respects. See "Certain Relationships and
Related Party Transactions."

PROVISIONS OF THE SHAREHOLDERS AGREEMENT IMPOSE SIGNIFICANT OPERATING AND
FINANCIAL RESTRICTIONS ON OUR BUSINESS.

     Under the shareholders agreement referred to above, specified actions
require the approval of representatives of CSFB Private Equity, until such time
as we consummate a public common stock offering for at least $100 million in
gross proceeds to us. Such actions include certain acquisitions by us, the
selection of a chief executive officer, certain debt restructurings and any
liquidation or dissolution of us. You should consider that we and our
stockholders may be unable to agree with CSFB Private Equity on the
implementation of such fundamental transactions and other matters. This sort of
disagreement may materially and adversely affect us. In addition, directors
designated by Heartland could block actions even if other directors deem them
advisable.

RISKS RELATED TO THE EXCHANGE NOTES

WE MAY NOT BE ABLE TO MANAGE OUR BUSINESS AS WE MIGHT OTHERWISE DO SO DUE TO
OUR HIGH DEGREE OF LEVERAGE.

     We have debt that is substantial in relation to our stockholders' equity
and we expect to incur further debt in the future to finance acquisitions. As
of June 30, 2002, we had approximately $830.4 million of outstanding debt
(without giving effect to the purchase of $78.2 million aggregate principal
amount of our outstanding 4.5% convertible subordinated debentures due 2003 in
August 2002) and approximately $671.4 million of stockholders' equity. The
degree to which we are leveraged will have important consequences, including
the following:

     o our ability to obtain additional financing in the future for working
       capital, capital expenditures, acquisitions, business development efforts
       or general corporate purposes may be impaired;


                                       14


     o a substantial portion of our cash flow from operations will be dedicated
       to the payment of interest and principal on our indebtedness, thereby
       reducing the funds available to us for other purposes, including our
       obligations to pay rent in respect of our significant operating leases;

     o our operations are restricted by our debt instruments, which contain
       material financial and operating covenants, and those restrictions will
       limit, among other things, our ability to borrow money in the future for
       working capital, capital expenditures, acquisitions, rent expense or
       other purposes;

     o indebtedness under our credit facility and the financing cost associated
       with our accounts receivable facility are at variable rates of interest,
       which makes us vulnerable to increases in interest rates;

     o our leverage may place us at a competitive disadvantage as compared with
       our less leveraged competitors;

     o our leverage will make us more vulnerable in the event of a downturn in
       general economic conditions or in any of our businesses; and

     o our flexibility in planning for, or reacting to, changes in our business
       and the industry in which we operate may be limited.

     Our ability to service our debt and other obligations will depend on our
future operating performance, which will be affected by prevailing economic
conditions and financial, business and other factors, many of which are beyond
our control. See "Description of Other Indebtedness and Our Preferred Stock"
included in this prospectus and "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital Resources"
included in our Quarterly Reports on Form 10-Q incorporated by reference in
this prospectus.

RESTRICTIONS IN OUR CREDIT FACILITY AND UNDER THE INDENTURE GOVERNING THE
EXCHANGE NOTES LIMIT OUR ABILITY TO TAKE CERTAIN ACTIONS.

     Our credit facility and the indenture governing the exchange notes will
contain covenants that restrict our ability to:

     o pay dividends or redeem or repurchase capital stock;

     o incur additional indebtedness and grant liens;

     o make acquisitions and joint venture investments;

     o sell assets; and

     o make capital expenditures.

     Our credit facility also requires us to comply with financial covenants
relating to, among other things, interest coverage and leverage. In addition,
our accounts receivable facility contains covenants similar to those in our
credit facility and include requirements regarding the purchase and sale of
receivables. We cannot assure you, however, that we will be able to satisfy
these covenants in the future or that we will be able to pursue our new
business strategies within the constraints of these covenants. If we cannot
comply with these covenants, we will be in default and unable to access
required liquidity from our revolving credit and accounts receivable facilities
and unable to make payments in respect of the notes. In addition, our accounts
receivable facility contains concentration limits with respect to the
percentage of receivables we can sell from a particular customer. The
concentration limits are based on the credit ratings of such particular
customer. While we may implement credit hedging strategies to offset this risk,
if one or more of our customers were to have its credit ratings downgraded and
consequently the amount of receivables of such customer that we could sell were
to decrease, our business could be materially adversely affected.

     Our ability to comply with our covenants may be affected by events beyond
our control, including prevailing economic, financial and industry conditions.
The breach of our covenants could result in an


                                       15




event of default under our credit facility or under the indenture governing the
exchange notes, which could cause an event of default under our accounts
receivable facility and our equipment lease financing. Such breach would permit
the lenders to declare all amounts borrowed thereunder to be due and payable,
together with accrued interest, and the commitments of the lenders to make
further extensions of credit under our credit facility could be terminated. In
addition, such breach may cause a termination of our accounts receivable
facility and of our various sale-leaseback facilities. If we were unable to
secure a waiver from our lenders or repay our credit facility indebtedness, our
secured lenders could proceed against their collateral and our lessors could
prevent us from using our valuable facilities and equipment that are under
lease. We do not presently expect that alternative sources of financing will be
available to us under these circumstances or available on attractive terms.

YOUR RIGHT TO RECEIVE PAYMENT ON THE EXCHANGE NOTES IS JUNIOR TO THE RIGHT OF
THE HOLDERS OF ALL OF OUR EXISTING SENIOR INDEBTEDNESS AND POSSIBLY TO ALL OF
OUR FUTURE BORROWINGS.

     The exchange notes are general unsecured obligations, junior in right of
payment to all of our existing senior indebtedness, including indebtedness
under our credit facility, and all of our future borrowings, except any future
indebtedness that expressly provides that it ranks equally with, or is
subordinated in right of payment to, the notes. As a result, upon any
distribution to our creditors in a bankruptcy, liquidation, reorganization or
similar proceeding relating to us or our property, the holders of our senior
indebtedness will be entitled to be paid in full in cash before any payment may
be made with respect to the notes. In addition, all payments on the exchange
notes will be blocked in the event of a payment default on senior indebtedness
and may be blocked for up to 179 of 360 consecutive days in the event of
certain non-payment defaults on designated senior indebtedness.

     In the event that we are declared bankrupt, become insolvent or are
liquidated, reorganized or involved in a similar proceeding, holders of the
exchange notes will participate with trade creditors and all other holders of
our subordinated indebtedness in the assets remaining after we have paid all of
the senior indebtedness. The indenture governing the exchange notes requires
that amounts otherwise payable to holders of the exchange notes in a bankruptcy
or similar proceeding be paid to holders of any remaining senior indebtedness
instead. In any of these cases, our assets may be insufficient to pay all of
our creditors, and holders of the exchange notes are likely to receive less,
proportionally, if any, than holders of our senior indebtedness, including the
lenders under our credit facility. We may be permitted to incur substantial
additional indebtedness, including senior indebtedness, in the future, under
the terms of the indenture governing the exchange notes.

YOUR RIGHT TO ENFORCE REMEDIES IS LIMITED BY THE RIGHTS OF SECURED CREDITORS,
AND CLAIMS OF HOLDERS OF EXCHANGE NOTES WILL EFFECTIVELY RANK JUNIOR TO CLAIMS
OF SECURED CREDITORS AND CLAIMS OF CREDITORS OF OUR FOREIGN SUBSIDIARIES.

     The exchange notes will not be secured by any of our assets. Our
obligations under our credit facility are secured by substantially all of our
owned assets and those of our subsidiary guarantors and a pledge of the capital
stock of each guarantor and two-thirds of the capital stock of our first tier
foreign subsidiaries. If we become insolvent or are liquidated, or if payment
under our credit facility is accelerated, the lenders under our credit facility
would be entitled to exercise the remedies available to a secured lender under
applicable law. Therefore, our bank lenders or other secured creditors will
have a claim on our assets before holders of the exchange notes.

     In addition, only our subsidiaries that also guarantee our obligations
under the credit facility guarantee the exchange notes. This includes all of
our domestic subsidiaries other than our receivables subsidiary and our special
purpose subsidiary that owns a minority investment in Saturn. However, we have
significant non-U.S. assets and operations. For the year ended December 31,
2001, after giving effect to the TriMas divestiture, our non-U.S. subsidiaries
had sales of approximately $265 million and total net operating assets of
approximately $259 million.


                                       16





WE MAY BE PREVENTED FROM FINANCING, OR MAY NOT HAVE THE ABILITY TO RAISE FUNDS
NECESSARY TO FINANCE, THE CHANGE OF CONTROL OFFER REQUIRED BY THE INDENTURE
GOVERNING THE EXCHANGE NOTES.

     Upon certain change of control events, each holder of outstanding exchange
notes may require us to purchase all or a portion of our exchange notes at a
purchase price equal to 101% of the principal amount thereof, plus accrued and
unpaid interest, if any, to the date of purchase. Our ability to purchase the
exchange notes upon a change of control event may be prohibited by the terms of
our credit facility or future credit facilities. Future agreements may contain
a similar provision. Certain change of control events will constitute events of
default under our credit facility and termination events under our accounts
receivable facility and, absent a consent or waiver, we would be required to
repay all amounts owed by us under our credit facility and wind down our
accounts receivable facility. We cannot assure you that we would be able to
repay amounts outstanding under our credit facility or replace our accounts
receivable facility. The source of funds for any purchase of notes would be our
available cash or cash generated from other sources, including borrowings,
sales of assets, sales of equity or funds provided by an existing or new
controlling person. We cannot assure you that any of these sources will be
available. Any requirement to offer to purchase any outstanding exchange notes
may result in us having to refinance our outstanding debt or obtain necessary
consents under our other debt agreements to repurchase the exchange notes,
which we may not be able to do. In such case, our failure to purchase exchange
notes following a change of control would constitute an event of default under
the indenture governing the exchange notes which would, in turn, constitute a
default under our credit facility. In addition, even if we were able to
refinance such debt, such financing may be on terms unfavorable to us.

FEDERAL AND STATE STATUTES ALLOW COURTS, UNDER SPECIFIC CIRCUMSTANCES, TO VOID
GUARANTEES AND REQUIRE HOLDERS OF EXCHANGE NOTES TO RETURN PAYMENTS RECEIVED
FROM GUARANTORS.

     Creditors of any business are protected by fraudulent conveyance laws
which differ among various jurisdictions, and these laws may apply to the
issuance of the guarantees by our subsidiaries. A guarantee may be voided by a
court, or subordinated to the claims of other creditors, if

     o that guarantee was incurred by a subsidiary with actual intent to
       hinder, delay or defraud any present or future creditor of the
       subsidiary, or

     o that subsidiary did not receive fair consideration, or reasonably
       equivalent value, for issuing its guarantee, and the subsidiary

       -- was insolvent or was rendered insolvent by reason of issuing the
          guarantee,

       -- was engaged or about to engage in a business or transaction for which
          the remaining assets of the subsidiary constituted unreasonably small
          capital, or

       -- intended to incur, or believed that it would incur, debts beyond its
          ability to pay as they matured.

     We cannot be certain as to the standard that a court would use to
determine whether the guarantor subsidiaries were solvent upon issuance of the
guarantee or, regardless of the actual standard applied by the court, that the
issuance of the guarantee of the exchange notes would not be voided. If a
guarantee of a subsidiary was voided as a fraudulent conveyance or held
unenforceable for any other reason, holders of the exchange notes would be
solely our creditors and creditors of our other subsidiaries that have
guaranteed the exchange notes. The exchange notes then would be effectively
subordinated to all obligations of that subsidiary. Since the Issuer is a
holding company, if all guarantees were voided, that would result in the holder
of exchange notes having claims that would not be paid prior to substantially
all of the other debt and liabilities of the consolidated group of entities. To
the extent that the claims of the holders of the exchange notes against any
subsidiary were subordinated in favor of other creditors of such subsidiary,
such other creditors would be entitled to be paid in full before any payment
could be made on the notes. If one or more of the guarantees are voided or
subordinated, we cannot assure you that after providing for all prior claims,
there would be sufficient assets remaining to satisfy the claims of holders of
the exchange notes.


                                       17



     Based upon financial and other information, we believe that the exchange
notes and the guarantees are being incurred for proper purposes and in good
faith and that we are and each subsidiary is solvent and will continue to be
solvent after this offering is completed, will have sufficient capital for
carrying on its business after such issuance and will be able to pay its debts
as they mature. We cannot assure you, however, that a court reviewing these
matters would agree with us. A legal challenge to a guarantee on fraudulent
conveyance grounds may focus on the benefits, if any, realized by the
subsidiary as a result of our issuance of the exchange notes.

YOU CANNOT BE SURE AN ACTIVE TRADING MARKET FOR THE EXCHANGE NOTES WILL DEVELOP.

     There has previously been only a limited secondary market, and no public
market, for the original notes. The exchange notes are an exchange issue of
securities, have no established trading market, and may not be widely
distributed. We do not intend to list the exchange notes on any national
securities exchange or the Nasdaq stock market or to seek the admission thereof
to trading on any automated quotation system. No assurance can be given that an
active public or other market will develop for the exchange notes or as to the
liquidity of or the trading market for the exchange notes. If a trading market
does not develop or is not maintained, holders of the exchange notes may
experience difficulty in reselling the exchange notes or may be unable to sell
them at all. If a market for the exchange notes develops, any such market may
be discontinued at any time. If a public trading market develops for the
exchange notes, future trading prices of the exchange notes will depend on many
factors, including, among other things, prevailing interest rates, our results
of operations and the market for similar securities, and the price at which the
holders of exchange notes will be able to sell such exchange notes is not
assured and the exchange notes could trade at a premium or discount to their
purchase price or face value. Depending on prevailing interest rates, the
market for similar securities and other factors, including our financial
condition, the exchange notes may trade at a discount from their principal
amount.

RESALES OF THE EXCHANGE NOTES MAY BE SUBJECT TO FURTHER RESTRICTIONS IN SOME
JURISDICTIONS.

     Each broker-dealer that receives exchange notes for its own account
pursuant to the exchange offer must acknowledge that it will deliver a
prospectus meeting the requirements under the Securities Act in connection with
any resale of such exchange notes. We have agreed to use our best efforts to
make this prospectus available to any participating broker-dealer for use in
connection with any such resale. See "Plan of Distribution" below. However to
comply with the securities laws of certain jurisdictions, if applicable, you
may not offer or sell the exchange notes unless someone has registered or
qualified them for sale in such jurisdictions or an exemption from registration
or qualification is available.

- ----------
(1)   In connection with the original notes offering, we amended and restated
      our credit facility to replace our original tranche A, B and C term loans
      with a new $400 million tranche D term loan payable in semi-annual
      installments of $0.5 million with the remaining outstanding balance due
      December 31, 2009. In addition to the term loan, the credit facility also
      includes a revolving credit facility with a total principal amount
      commitment of $250 million. The senior revolving credit facility matures
      on May 28, 2007 and the senior term loan facility matures on December 31,
      2009. The obligations under the credit facility are collateralized by
      substantially all of our assets and are guaranteed by substantially all
      of our domestic subsidiaries. In addition, our receivables facility
      provides us with up to $225 million of availability, of which no amount
      was utilized at June 30, 2002. See "Description of Other Indebtedness and
      Our Preferred Stock" in this prospectus and "Management's Discussion and
      Analysis of Financial Condition and Results of Operations--Liquidity and
      Capital Resources" contained in our Quarterly Report on Form 10-Q for the
      period ended June 30, 2002 incorporated by reference in this prospectus.

(2)   Our subordinated debentures ($176.7 million principal amount at June 30,
      2002) were convertible into common stock prior to the November 2000
      acquisition, but have since become convertible into an amount of cash
      that is equivalent to the cash consideration paid in the November 2000
      acquisition to our former common stockholders. Since they are convertible
      at a conversion price of $31.00 for the amount of the consideration paid
      for a share of common stock in the acquisition (approximately $16.90), we
      do not expect them to be converted into cash prior to maturity. As a
      result of our adoption of purchase accounting, the subordinated
      debentures are recorded at fair value, which was approximately 80% of
      their principal amount, less accumulated accretion of the discount. We
      applied approximately $127.5 million of proceeds from the TriMas
      divestiture to the repurchase of subordinated debentures by June 30,
      2002. On August 21, 2002, we completed an offer to purchase up to, and
      subsequently accepted for purchase, $78.2 million of our subordinated
      debentures. See "Description of Other Indebtedness and Our Preferred
      Stock."


                                       20



(3)   Other debt includes industrial revenue bonds, foreign debt and capital
      lease obligations.

(4)   These shares of redeemable preferred stock are not mandatorily redeemable
      prior to the maturity of the exchange notes, but constitute redeemable
      capital stock in accordance with generally accepted accounting principles
      since they contain mandatory redemption provisions. As such, the
      preferred stock is required to be excluded from shareholders' equity. Of
      such shares, $36.1 million in liquidation preference of Series A
      preferred stock was issued in the recapitalization and is mandatorily
      redeemable in December 2012 and $18.5 million in liquidation preference
      of Series B preferred stock was issued for the GMTI acquisition and is
      mandatorily redeemable in June 2013. For accounting purposes, the Series
      A preferred stock is valued at a discount to reflect the value of the
      common stock for which such preferred stock was exchanged in the November
      2000 acquisition. In the event of certain equity offerings or a change of
      control we may be required to offer to purchase the preferred stock from
      the holders thereof. See "Description of Other Indebtedness and Our
      Preferred Stock."

(5)   Since we have the obligation to pay cash in respect of these restricted
      stock awards at the option of the restricted stockholder, the awards have
      been excluded from shareholders' equity, as some or all of these shares
      outstanding may represent temporary equity. These obligations arose in
      January 2002 and will arise again in January 2003 and January 2004. On
      January 14, 2002, holders of awards representing approximately $14.3
      million elected to receive cash, of which approximately $8.3 million was
      paid in July 2002. Pursuant to the stock purchase agreement related to
      the TriMas divestiture, TriMas is obligated to reimburse us for all cash
      actually paid to former and present TriMas employees and 42.01% of the
      cash actually paid to former and present corporate employees not
      separately identifiable as TriMas employees. This obligation extends to
      the January 14, 2002 extended payment and our future obligations in
      January 2003 and January 2004. The receivable for these amounts from
      TriMas is included in our accounts receivable on our pro forma balance
      sheet. For a discussion of our obligations to fund cash in respect of our
      restricted stock awards, see "Management's Discussion and Analysis of
      Financial Condition and Results of Operations--Liquidity and Capital
      Resources" included in our Quarterly Report on Form 10-Q for the period
      ended June 30, 2002 incorporated by reference in this prospectus and

      Purchase Agreement" in this prospectus.

                   UNAUDITED PRO FORMA FINANCIAL INFORMATION

     The following unaudited pro forma condensed consolidated financial
information has been derived from our audited and unaudited historical
financial statements included in the Annual Report on Form 10-K and the
Quarterly Report on Form 10-Q for the period ended June 30, 2002 incorporated
by reference in this prospectus, adjusted to give pro forma effect to the
TriMas divestiture and the issuance of and application of proceeds from the
original notes.

     The unaudited pro forma condensed consolidated statements of operations
for the year ended December 31, 2001 and the six months ended June 30, 2002
give pro forma effect to the TriMas divestiture and the issuance of the
original notes as if each had occurred on January 1, 2001. On November 28,
2000, Metaldyne was acquired by an investor group led by Heartland Industrial
Partners, L.P. and Credit Suisse First Boston Equity Partners, L.P. We did not
recognize any gain or loss as a result of the TriMas divestiture due to the
continuing contractual control of TriMas by Heartland.

     The unaudited pro forma condensed consolidated statements of operations
are presented for informational purposes only and do not purport to represent
what our results of operations would actually have been had the referenced
TriMas divestiture or the issuance of the original notes occurred at such time
or to project our results of operations for any future period or date.

     The pro forma adjustments are based upon available information and various
assumptions that we believe are reasonable. The pro forma adjustments and
certain assumptions are described in the accompanying notes. Other information
included under this heading has been presented to provide additional analysis.

     The unaudited pro forma condensed consolidated statements of operations
should be read in conjunction with the "Management's Discussion and Analysis of
Financial Condition and Results of Operations" section and our historical
financial statements and the related notes to such financial statements
contained in our Annual Report on Form 10-K and Quarterly Report on Form 10-Q
for the period ended June 30, 2002 incorporated by reference in this
prospectus.

  NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS

The Unaudited Pro Forma Condensed Consolidated Statements of Operations for the
year ended December 31, 2001 and the six months ended June 30, 2002 include
adjustments necessary to reflect the estimated effect of the TriMas divestiture
and the assumed use of proceeds from the original notes offering as if they had
each occurred on January 1, 2001.


(1)   Represents the reclass of freight revenue, $8.0 million for the fiscal
      year ended December 31, 2001 included in net sales in the separate
      financial statements of TriMas from net sales to cost of sales. As
      Metaldyne has historically included these amounts in cost of sales on a
      consolidated basis, this adjustment eliminates the impact in the separate
      financial statements of TriMas.


(2)   Represents the adjustment to TriMas historical financial statements to
      reflect certain capital leases entered into in early 2002 as operating
      leases, consistent with Metaldyne's accounting for sale-leaseback
      transactions. For accounting purposes, Metaldyne's guarantee on certain
      sale-leaseback transactions required TriMas to record operating leases at
      Metaldyne as capital leases in TriMas' separate financial statements. As
      Metaldyne has historically accounted for these leases as operating leases
      on a consolidated basis, this adjustment eliminates the impact of the
      capital lease accounting in the separate financial statements of TriMas.


(3)   Represents the pro forma increase in selling, general and administrative
      expenses resulting from lower management fees charged to TriMas under the
      terms of a corporate services agreement described elsewhere herein.

- ----------
      (a)   Adjustment to eliminate the historical fee charged to TriMas for
            corporate support and administrative services through the period
            ended June 6, 2002.

      (b)   Historical direct costs of TriMas related to corporate staff and
            other expenses recorded by Metaldyne and allocated to TriMas
            through the management fee through the period ended June 6, 2002.
            Going forward TriMas will incur these costs in addition to the
            Corporate Services Agreement described below.

      (c)   Under the terms of a corporate services agreement, TriMas has
            agreed to pay Metaldyne an annual services fee of $2.5 million
            for human resources, MIS, treasury services, internal audit, tax,
            legal services and other general corporate services, less amounts
            directly assumed by TriMas.

(4)   Represents the adjustment to reduce Metaldyne's historical interest
      expense for debt repayments from the proceeds of the TriMas divestiture
      compared with the historical interest expense allocated to TriMas. The
      pro forma interest savings are calculated using interest rates in effect
      during the pro forma periods noted (varied from 8.75% to 5.75% for
      Tranche A and from 9.5% to 6.5% for Tranche B and C).

              CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

METALDYNE SHAREHOLDERS AGREEMENT

     Heartland, CFSB Private Equity, Masco Corporation, Richard Manoogian,
their various affiliates and certain other stockholders of Metaldyne
Corporation are parties to a shareholders agreement regarding their ownership
of our common stock. References to a shareholder below refer only to those that
are party to the shareholders agreement. References to Heartland and CSFB
Private Equity refer to all of their respective affiliated entities
collectively, unless otherwise noted. Owners of an aggregate of approximately
94% of our outstanding common stock are party to the shareholders agreement.

     Election of Directors. The shareholders agreement provides that the
parties will vote their shares of common stock in order to cause:

     (1)    an amendment to our bylaws to provide that the authorized number of
            directors on our board of directors shall be as recommended by
            Heartland in its sole discretion; and

     (2)    the election to the board of directors of:

            o     such number of directors as shall constitute a majority of the
                  board of directors as designated by Heartland;

            o     one director designated by Masco; and

            o     one director designated by CSFB Private Equity after
                  consultation with Heartland.

     Masco's ability to designate one director to the board of directors will
terminate when it ceases to own a majority of the shares of common stock held
by it as of the closing of the recapitalization subject to certain exceptions.
CSFB Private Equity's ability to designate one director to the board of
directors will terminate when it ceases to own a majority of the shares of
common stock held by it as of the closing of the November 2000 acquisition.

     Transfers of Common Stock. Prior to the date we have consummated a public
offering of our common stock of at least $100 million, or a qualifying public
equity offering, the shareholders agreement restricts transfers of common stock
except for transfers: (1) to a permitted transferee of a stockholder, (2)
pursuant to the "right of first offer" provision discussed below, (3) pursuant
to the "tag-along" provision discussed below, (4) pursuant to the "drag-along"
provision discussed below and (5) pursuant to an effective registration
statement or pursuant to Rule 144 under the Securities Act.

     Right of First Offer. The shareholders agreement provides that prior to a
qualifying public equity offering no stockholder party to the agreement may
transfer any of its shares other than to a permitted transferee of such
stockholder or pursuant to the "tag-along" and "drag-along" provisions unless
such stockholder shall offer such shares to us. We shall have the option for 15
business days to purchase such shares. If we decline to purchase the shares,
then Heartland shall have the right to purchase such shares for an additional
10 business day period. Any shares not purchased by us or Heartland can be sold
by such stockholder party to the agreement at a price not less than 90% of the
price offered to us or Heartland.

     Tag-Along Rights. The shareholders agreement grants to the stockholders
party to the agreement, subject to certain exceptions, in connection with a
proposed transfer of common stock by Heartland or its affiliates, the right to
require the proposed transferee to purchase a proportionate percentage of the
shares owned by the other stockholders at the same price and upon the same
economic terms as are being offered to Heartland. These rights terminate upon a
qualifying public equity offering.

     Drag-Along Rights. The shareholders agreement provides that when Heartland
and its affiliates enter into a transaction resulting in a substantial change
of control of us, Heartland has the right to require the other stockholders to
sell a proportionate percentage of shares of common stock in such transaction
as Heartland is selling and to otherwise vote in favor of the transactions
effecting such substantial change of control. These rights terminate upon a
qualifying public equity offering.


                                       28




     Information.  Pursuant to the shareholders agreement, each stockholder
party to the agreement is entitled to receive our quarterly and annual
financial statements. In addition, such stockholders who maintain 25% of their
original equity investment in us will be entitled to receive prior to a
qualifying public equity offering certain monthly financial information and
certain other information as they may reasonably request and will have the
opportunity to meet with our senior management on an annual basis and certain
stockholders will be able to meet quarterly with our senior management.

     Observer Rights. Our shareholders who are also investors, or HIP
co-investors, in one of Heartland's funds and have invested at least $40
million in our common stock or own at least 10% of our outstanding common stock
have the right to attend all meetings of the board of directors, including
committees thereof, solely in a non-voting observer capacity. These rights
terminate upon a qualifying public equity offering.

     Preemptive Rights. Subject to certain exceptions, the shareholders
agreement provides that if we issue, sell or grant rights to acquire for cash
any shares of common stock or options, warrants or similar instruments or any
other security convertible or exchangeable therefor, or equity interests, or
any equity security linked to or offered or sold in connection with any of our
equity interests, then we will be obligated to offer certain stockholders or
Heartland the right to purchase at the sale price and on the same terms and
conditions of the sale, such amount of shares of common stock or such other
equity security as would be necessary for such stockholders or Heartland to
maintain its then current beneficial ownership interest in us. These rights
terminate upon a initial public offering by us.

     Affiliate Transactions. Subject to certain exceptions, the shareholders
agreement provides that Heartland and its affiliates will not enter into
transactions with us or our subsidiaries involving consideration in excess of
$1 million without the approval of Masco Corporation and the HIP co-investors.

     Registration Rights. The shareholders agreement provides the stockholders
party to the agreement with unlimited "piggy-back" rights each time we file a
registration statement except for registrations relating to (1) shares
underlying management options and (2) an initial public offering consisting of
primary shares. In addition, on the earlier of (1) five years after the closing
of the recapitalization or (2) an initial public offering of our equity
interests, Heartland, CSFB Private Equity, Masco Corporation and Richard
Manoogian have the ability to demand the registration of their shares, subject
to various holdback and other agreements. The shareholders agreement grants two
demand registrations to Masco Corporation, one demand registration to Richard
Manoogian, three demand registrations to CSFB Private Equity and an unlimited
number of demands to Heartland.

     Approval and Consultation Rights. The shareholders agreement provides that
prior to a qualifying public equity offering we will consult with CSFB Private
Equity with respect to any issues that in our good faith judgment are material
to our business and operations. In addition, prior to a qualifying public
equity offering, CSFB Private Equity will have the right to approve:

     o   certain acquisitions by us;

     o   the selection of a chief executive officer;

     o   certain debt restructurings; and

     o   any liquidation or dissolution of us.


MONITORING AGREEMENT

     We and Heartland are parties to a monitoring agreement pursuant to which
Heartland is engaged to provide consulting services to us with respect to
financial and operational matters. Heartland received a fee of $4 million for
such services in 2001, plus reimbursement of expenses. Commencing with 2002,
Heartland is entitled to receive a fee for such services equal to the greater
of (1) $4 million or (2) 0.25% of our total assets. In addition to providing
ongoing consulting services, Heartland has also agreed to assist in
acquisitions, divestitures and financings, for which Heartland will receive a
fee


                                       29



equal to 1% of the value of such transaction. The monitoring agreement also
provides that Heartland will be reimbursed for its reasonable out-of-pocket
expenses.


CORPORATE SERVICES AGREEMENT

     Under a corporate services agreement, Masco Corporation provides us use of
its data processing equipment and services, certain research and development
services, corporate administrative staff and other support services in return
for payment of an annual fee. The fee for such services is to be mutually
agreed to by us and Masco and was $415,000 for 2001 and will not exceed
$500,000 for 2002. This agreement also provides for various license rights and
confidential treatment of information which may arise from Masco Corporation's
performance of research and development services on our behalf.


CORPORATE OPPORTUNITIES AGREEMENT

     Masco Corporation and we are parties to a corporate opportunities
agreement which materially restricts the ability of either party to acquire or
otherwise make an investment in a business if the other party has an investment
in such business, except that Masco Corporation is unrestricted from investing
in any company engaged in home improvement or building products or service
businesses. The agreement terminates on the earlier of November 28, 2002 or
nine months after corporate services are no longer required to be provided
under the corporate services agreement.


TRIMAS STOCK PURCHASE AGREEMENT

     The following is a summary of certain terms of the stock purchase
agreement among Heartland, TriMas and us relating to the TriMas divestiture.
The TriMas divestiture closed on June 6, 2002.

 Consideration

     Pursuant to the stock purchase agreement, Heartland and other investors
acquired approximately 66% of TriMas' fully diluted common stock by making a
cash investment in TriMas of $265 million. As a result of this investment and
the other related transactions, we received $840 million in cash, retirement of
debt owed by TriMas' subsidiaries to us and our other subsidiaries or owed
directly by TriMas under the our credit agreement and the repurchase of the
balance of TriMas originated receivables previously sold under our receivables
facility. In addition, we retained shares of TriMas common stock valued at $120
million and received a warrant to purchase shares of common stock valued at $15
million.

 Employee Matters

     Pursuant to the stock purchase agreement, each outstanding option to
purchase our common stock which had not vested as of June 6, 2002 and which is
held by transferred employees was canceled on June 6, 2002. Each option held by
some former employees which vested on or prior to June 6, 2002 was replaced by
options to purchase common stock of TriMas, with appropriate adjustments.

     TriMas will promptly reimburse us upon our written demand for (i) cash
actually paid in redemption of certain restricted shares held by certain
employees under restricted stock awards, and (ii) 42.01% of the amount of cash
actually paid to certain other employees by us in redemption of restricted
stock awards held by such employees. TriMas will also have certain other
obligations to reimburse us for the allocated portion of its current and former
employee related benefit responsibilities.

 Indemnification

     Subject to certain limited exceptions, we, on the one hand, and TriMas, on
the other hand, retained the liabilities associated with our respective
businesses. Accordingly, TriMas will indemnify us and hold us harmless from all
liabilities associated with TriMas and its subsidiaries and their respective
operations and assets, whenever conducted, and we will indemnify and hold
harmless Heartland and


                                       30




TriMas from all liabilities associated with us and our subsidiaries (excluding
TriMas and the other acquired TriMas entities) and their respective operations
and assets, whenever conducted. In addition, we and TriMas have each agreed to
indemnify one another for their allocated share of (57.99% in our case and
42.01% in the case of TriMas) of liabilities not readily associated with either
business, or otherwise addressed including certain costs related to the
November 2000 acquisition. There are also indemnification provisions relating
to certain other matters intended to effectuate other provisions of the
agreement. These indemnification provisions will survive indefinitely and are
subject to a $50,000 deductible.


TRIMAS SHAREHOLDERS AGREEMENT

     Heartland, we and other investors are parties to a shareholders agreement
regarding ownership of TriMas common stock. References to Heartland refer to
all of its affiliated entities collectively, unless otherwise noted. The
agreement contains certain other covenants for the benefit of the shareholders
parties thereto.

     Election of Directors. The TriMas shareholders agreement provides that the
parties will vote their shares of common stock in order to cause (1) the
election to the board of directors of such number of directors as shall
constitute a majority of the board of directors as designated by Heartland; and
(2) the election to the board of directors of up to two directors designated by
us.

     Transfers of Common Stock. Prior to the date TriMas consummates a
qualifying public equity offering, the TriMas shareholders agreement restricts
transfers of common stock except for certain transfers, including (1) to the
permitted transferee of a stockholder, (2) pursuant to the "right of first
offer" provision discussed below, (3) pursuant to the "tag-along" provision
discussed below, (4) pursuant to the "drag-along" provision discussed below and
(5) pursuant to an effective registration statement or pursuant to Rule 144
under the Securities Act.

     Right of First Offer. The TriMas shareholders agreement provides that,
prior to a TriMas qualifying public equity offering, no stockholder party to
the agreement may transfer any of its shares other than to a permitted
transferee of such stockholder or pursuant to the "tag-along" and "drag-along"
provisions unless such stockholder shall offer such shares to us. If TriMas
declines to purchase the shares, then Heartland shall have the right to
purchase such shares. Any shares not purchased by us or Heartland can be sold
by such stockholder party to the agreement at a price not less than 90% of the
price offered to us or Heartland.

     Tag-Along Rights. The TriMas shareholders agreement grants to the
stockholders party to the agreement, subject to certain exceptions, in
connection with a proposed transfer of TriMas common stock by Heartland or its
affiliates, the right to require the proposed transferee to purchase a
proportionate percentage of the shares owned by the other stockholders at the
same price and upon the same economic terms as are being offered to Heartland.
These rights terminate upon a TriMas qualifying public equity offering.

     Drag-Along Rights. The TriMas shareholders agreement provides that when
Heartland and its affiliates enter into a transaction resulting in a
substantial change of control of TriMas, Heartland has the right to require the
other stockholders to sell a proportionate percentage of shares of common stock
in such transaction as Heartland is selling and to otherwise vote in favor of
the transactions effecting such substantial change of control. These rights
terminate upon a TriMas qualifying public equity offering.

     Registration Rights. The TriMas shareholders agreement provides the
stockholders party to the agreement with unlimited "piggy-back" rights each
time we file a registration statement except for registrations relating to (1)
shares underlying management options and (2) an initial public offering
consisting of primary shares. In addition, following an initial public offering
of the Issuer, Heartland and we have the ability to demand the registration of
their shares, subject to various hold back, priority and other agreements. The
TriMas shareholders agreement grants three demand registrations to us and an
unlimited number of demands to Heartland.


                                       31




     Information. Pursuant to the TriMas shareholders agreement, we are
entitled to receive certain periodic, quarterly and annual financial
statements.


     Preemptive Rights. Subject to certain exceptions, the TriMas shareholders
agreement provides that if TriMas issues, sells or grants rights to acquire for
cash any shares of common stock or options, warrants or similar instruments or
any other security convertible or exchangeable therefor, or equity interests,
or any equity security linked to or offered or sold in connection with any of
TriMas' equity interests, then TriMas will be obligated to offer us and certain
other stockholders the right to purchase at the sale price such amount of
shares of common stock or such other equity interests as would be necessary for
us and such other stockholders to maintain our then current beneficial
ownership interest in TriMas. These rights terminate upon an initial public
offering and we may not have the necessary capital to pursue these rights.


     Affiliate Transactions. Subject to certain exceptions, the TriMas
shareholders agreement provides that Heartland and its affiliates will not
enter into transactions with TriMas or any of its subsidiaries involving
consideration in excess of $1 million without certain approvals.

            DESCRIPTION OF OTHER INDEBTEDNESS AND OUR PREFERRED STOCK


CREDIT FACILITY


  GENERAL

     Metaldyne and Metaldyne Company LLC are party to a credit facility with
JPMorgan Chase Bank, as administrative agent and collateral agent, Credit
Suisse First Boston, as syndication agent, Comerica Bank, as documentation
agent, First Union National Bank, as documentation agent, National City Bank,
as documentation agent, Bank One, NA, as documentation agent, J.P. Morgan
Securities Inc. and Credit Suisse First Boston, as joint bookrunners and joint
lead arrangers, and the other lenders party thereto. In connection with the
TriMas divestiture, the credit facility was amended to reduce revolving credit
facility commitments to $250 million, permit the TriMas divestiture and
establish the use of proceeds therefrom and adjust financial covenants to
reflect the TriMas divestiture. On June 20, 2002 we amended and restated our
credit facility to permit us to reduce our receivables facility balances by
approximately $37.8 million and our original tranche A, B and C term loans with
the proceeds from the original notes issuance and a new $400 million tranche D
term loan that matures in December 2009 and bears interest at a lower rate and
provides us with certain additional covenant flexibility.

     The credit facility presently consists of a senior revolving credit
facility and the tranche D senior term loan facility. The revolving credit
facility is comprised of a total principal amount commitment of $250 million.
The tranche D facility is comprised of loans in a total principal amount of
$400 million as of September 3, 2002. Up to approximately $150 million of our
revolving credit facility is available for permitted acquisitions and we are
required to reserve $100 million of our revolving credit facility availability
equal to the outstanding principal amount of our 4.5% subordinated debentures
for retirement of such remaining debentures. The amendment and restatement
allowed us to use a portion of the proceeds from the original notes issuance to
reduce our receivables facility balances so that our debt balances are
correspondingly higher. The amendment and restatement also allowed us to
terminate our subordinated loan agreement with Masco Corporation pursuant to
which Masco had agreed to purchase up to $100 million of subordinated notes
from us. We were also released from our obligation to use the proceeds of the
notes to meet our obligations under our 4.5% convertible subordinated
debentures due 2003.

     The revolving credit facility matures on May 28, 2007 and the tranche D
facility matures on December 31, 2009.

     The obligations under the credit facility are secured and are
unconditionally and irrevocably guaranteed jointly and severally by us and each
of our existing and subsequently acquired or organized domestic subsidiaries
other than MTSPC, Inc. and Saturn Holdings (the holder of the equity interest
in Saturn), pursuant to the terms of a separate guarantee agreement.

     Although no foreign subsidiaries are currently borrowers under the credit
facility, such entities may borrow under the facility in the future.


     SECURITY INTERESTS

     Our borrowings under the credit facility are secured by a first priority
perfected security interest in:

     o the capital stock of Metaldyne Company LLC and all of the capital stock
       held by Metaldyne, Metaldyne Company LLC or any domestic subsidiary of
       Metaldyne and of each existing and subsequently acquired or organized
        subsidiary of Metaldyne (which pledge, in the case of any foreign
       subsidiary, shall be limited to 65% of the capital stock of such foreign
       subsidiary to the extent the pledge of any greater percentage would
       result in adverse tax consequences to Metaldyne or Metaldyne Company
       LLC); and


                                       33




     o all tangible and intangible assets of Metaldyne, Metaldyne Company LLC
       and each existing or subsequently acquired or organized domestic
       subsidiary of Metaldyne, other than MTSPC, Inc. and Saturn Holdings, with
       certain exceptions as set forth in the credit facility.


     INTEREST RATES AND FEES

     Borrowings under the credit facility will bear interest, at our option, at
either:

     o a base rate used by JPMorgan Chase Bank, plus an applicable margin; or

     o a eurocurrency rate on deposits for one, two, three or nine month
       periods (or nine or twelve month periods if, at the time of the
       borrowing, all lenders agree to make such a duration available), plus the
       applicable margin.

The applicable margin on loans is subject to change depending on our leverage
ratio. As of September 3, 2002, the applicable margin on our revolving loans
which are base rate loans was 2.75% and on eurocurrency loans was 3.75% and the
applicable margin on tranche D loans which are base rate loans was 1.75% and on
eurocurrency loans was 2.75%.

     We also pay the lenders a commitment fee on the unused commitments under
the credit facility equal to 0.75% per annum if less than 50% of the revolving
facility commitments are outstanding and 0.50% per annum is to be paid if 50%
or more of the revolving facility commitments are outstanding, in each case,
payable quarterly in arrears. The commitment fee is subject to reduction
depending on our leverage ratio.


     MANDATORY AND OPTIONAL REPAYMENT

     Subject to exceptions for reinvestment of proceeds and other exceptions
and materiality thresholds, we are required to prepay outstanding loans under
the credit facility with excess cash flow, the net proceeds of certain asset
dispositions, casualty and condemnation recovery events and incurrences of
permitted debt.

     We may voluntarily prepay loans under the credit facility without
prepayment premiums, in whole or in part, subject to minimum prepayments.


     COVENANTS

     The credit facility contains negative and affirmative covenants and
requirements affecting us and our subsidiaries. The credit facility contains
the following negative covenants and restrictions, among others: restrictions
on debt, liens, mergers, investments, loans, advances, guarantee obligations,
acquisitions, asset dispositions, sale-leaseback transactions, hedging
agreements, dividends and other restricted junior payments, stock repurchases,
transactions with affiliates, restrictive agreements, amendments to charter,
by-laws and other material documents. The credit facility also requires us and
our subsidiaries to meet certain financial covenants and ratios computed
quarterly.

     The credit facility contains the following affirmative covenants, among
others: mandatory reporting of financial and other information to the
administrative agent, notice to the administrative agent upon the occurrence of
certain events of default and other events, written notice of change of any
information affecting the identity of the record owner or the location of
collateral, preservation of existence and intellectual property, payment of
obligations, maintenance of properties and insurance, notice of casualty and
condemnation, access to properties and books by the lenders, compliance with
laws, use of proceeds and letters of credit, additional subsidiaries and

representations and warranties in any material respect, bankruptcy and
insolvency events, change of control, failure to maintain security interests,
specified ERISA


                                       34



events, one or more judgments for the payment of money in an aggregate amount
in excess of $15.0 million, the guarantees shall cease to be in full force and
effect or the subordination provisions of any of our subordinated debt are
found to be invalid.


SUBORDINATED DEBENTURES

     As of September 9, 2002, we have $100 million principal amount of 4.5%
convertible subordinated debentures due December 15, 2003 outstanding. Each
$1,000 principal amount of convertible debentures was convertible prior to the
November 2000 acquisition into shares of our common stock at a conversion price
of $31.00 a share. As a result of the November 2000 acquisition, the debentures
are convertible into the right to receive the merger consideration paid to
common stockholders in the November 2000 acquisition at a conversion price of
$31.00 per the consideration payable with respect to a share of common stock
and, accordingly, are not expected to be converted.

     Interest at a rate of 4.5% is paid semi-annually on the convertible
debentures on June 15 and December 15 to record holders of the convertible
debentures on the preceding June 1 or December 1, respectively. The debentures
mature on December 15, 2003. The debentures can be redeemed by us at any time,
in whole or in part, upon not less than thirty days' nor more than sixty days'
notice at a redemption price of 100.50% of the principal amount outstanding if
such redemption is prior to December 15, 2002; and at 100.00% of the principal
outstanding amount if such redemption is after December 15, 2002.

     The debentures are subordinated in right or payment to the prior
indefeasible payment and satisfaction in full of all of our existing and future
senior indebtedness and contains certain anti-layering language with respect to
certain subordinated debt financings. The debentures contain customary events
of default for a debt security of such type and do not contain any negative
covenants.


OTHER DEBT

     As of June 30, 2002, we had approximately $22.5 million of other debt
consisting primarily of industrial revenue bonds and government loans.


SERIES A PREFERRED STOCK

     In connection with the November 2000 acquisition, we issued 361,001 shares
of Series A Preferred Stock to Masco Corporation having an aggregate initial
liquidation preference of $36.1 million. The holders of Series A Preferred
Stock are entitled to receive, when, as and if declared by our board of
directors, out of legally available funds, cumulative dividends on each share
of Series A Preferred Stock for each quarterly dividend period at a rate of 13%
per annum for periods ending on or prior to December 31, 2005 and 15% per annum
for periods after December 31, 2005, plus, in either case, 2% per annum for any
period for which there are any accrued and unpaid dividends. Accrued and unpaid
dividends on the Series A Preferred Stock accrue additional dividends,
compounded quarterly, at the then applicable quarterly dividend rate.

     All then outstanding shares of Series A Preferred Stock are mandatorily
redeemable by us, out of legally available funds, on December 31, 2012 at a
redemption price of 100% of their liquidation preference, equal to $100 for
each share of Series A Preferred Stock. Additionally, at any time after
December 31, 2005, or at any time before such date using the net proceeds from
issuances of shares of our capital stock, we may redeem the Series A Preferred
Stock, in whole or in part, out of legally available funds, at our option by a
resolution of our board of directors, at a redemption price of 101% of their
liquidation preference. Immediately prior to authorizing or making any such
redemption, by resolution of our board of directors, to the extent that funds
are legally available therefor, we are required to declare a dividend on the
Series A Preferred Stock payable on the redemption date in an amount equal to
any accrued and unpaid dividends (including additional dividends) on the Series
A Preferred Stock as of such date and, if we do not have sufficient legally
available funds to declare and


                                       35




pay all dividends (including additional dividends) accrued at the time of such
redemption, any remaining accrued and unpaid dividends (including additional
dividends) are to be added to the redemption price.

     If a change in control, as defined in our certificate of incorporation,
occurs at any time, each holder of Series A Preferred Stock has the right to
require us to purchase such holder's Series A Preferred Stock, in whole or in
part, out of legally available funds, at a cash purchase price of 101% of their
liquidation preference, plus accrued and unpaid dividends to the purchase date.
Additionally, in the event of an equity offering triggering event, which is
defined in our certificate of incorporation and includes certain excess
proceeds from certain equity offerings and an initial public offering, each
holder of Series A Preferred Stock has the right to require us to purchase such
holder's Series A Preferred Stock, in whole or in part, out of legally
available funds, at a cash purchase price of 101% of their liquidation
preference, plus accrued and unpaid dividends to the purchase date, subject to
certain limitations set forth in our certificate of incorporation.

     In the event of any liquidation, dissolution or winding up of our affairs,
whether voluntary or otherwise, after payment or provision for payment of our
debts and other liabilities, the holders of Series A Preferred Stock are
entitled to receive, out of our remaining assets, $100 in cash for each share
of Series A Preferred Stock they hold, plus an amount equal to all dividends
(including additional dividends) accrued and unpaid on each share up to the
date fixed for distribution, before any distribution is made to the holders of
our common stock or any other stock ranking (as to any such distribution)
junior to the Series A Preferred Stock. With regard to rights to receive
dividends, mandatory redemption payments and distributions upon liquidation,
dissolution or winding up of our affairs, the Series A Preferred Stock ranks
prior to all our other capital stock outstanding at the time it was issued.

     Except as required by law or otherwise as set forth in our certificate of
incorporation, the holders of Series A Preferred Stock do not have any voting
rights or power to vote on any question or in any proceeding or to be
represented at, or to receive notice of, any stockholders meeting. The holders
of Series A Preferred Stock are entitled to one vote per share regarding
matters on which they are entitled to vote. The Series A Preferred Stock is not
convertible and has no preemptive rights.

     In case at any time (i) the equivalent of six or more full quarterly
dividends on the Series A Preferred Stock out of any eight consecutive
quarterly dividend periods are in arrears or (ii) we fail to make a mandatory
redemption of shares of Series A Preferred Stock or (iii) we fail to comply in
any material respect with the provisions in our certificate of incorporation
relating to a change in control or an equity offering triggering event, the
exclusive remedy for such matters, until cured, is that the number of members
of our board of directors is automatically be increased by one and the holders
of a majority of the outstanding shares of Series A Preferred Stock are
entitled, as a class, to the exclusion of the holders of all other classes or
series of our capital stock, to elect one director to fill the directorship so
created.

     Our certificate of incorporation provides that, so long as any shares of
the Series A Preferred Stock are outstanding, unless the vote or consent of the
holders of a greater number of shares is then required by law, except as
otherwise provided in our certificate of incorporation, the consent of the
holders of a majority of all of the outstanding shares of Series A Preferred
Stock is required for us to take certain actions which could adversely affect
holder of Series A Preferred Stock, including to allow any of our subsidiaries
to issue any preferred stock (other than to us or another one of our
subsidiaries) or to sell, lease or convey all or substantially all of our
assets or merge or consolidate with or into any other entity if as a result of
such transaction the Series A Preferred Stock would be cashed out for less than
100% (or, if the transaction would constitute a change of control, 101%) of
their liquidation preference, plus any accrued and unpaid dividends.


SERIES B PREFERRED STOCK

     In connection with the acquisition of GMTI, we issued 184,153 shares of
Series B Preferred Stock to representatives for the original sellers of GMTI
having an aggregate initial liquidation preference of $18,415,300.


                                       36



     The holders of Series B Preferred Stock are entitled to receive, when, as
and if declared by our board of directors, out of legally available funds,
cumulative dividends on each share of Series B Preferred Stock for each
semi-annual dividend period equal to their liquidation preference, in effect as
of the end of the immediately preceding semi-annual dividend period, of such
share multiplied by a rate equal to 5.75% (or the equivalent of 11.5% per
annum). Any accrued dividends not paid at the end of any semi-annual dividend
period is added to the liquidation preference of the Series B Preferred Shares
and dividends thereafter accrue on such amount so as to achieve semi-annual
compounding.

     All then outstanding shares of Series B Preferred Stock are mandatorily
redeemable by us, out of legally available funds, on June 15, 2013 at a
redemption price of 100% of their then liquidation preference, equal to $100
for each share of Series B Preferred Stock plus all amounts added at the end of
any semi-annual dividend period as provided in the immediately preceding
paragraph. Additionally, at any time, we may redeem the Series B Preferred
Stock, in whole or in part, out of legally available funds, at our option by a
resolution of our board of directors, at a redemption price of 100% of their
then liquidation preference. Immediately prior to authorizing or making any
such redemption, by resolution of our board of directors, to the extent that
funds are legally available therefor, we are required to declare a dividend on
the Series B Preferred Stock payable on the redemption date in an amount equal
to any accrued and unpaid dividends on the Series A Preferred Stock as of such
date and, if we do not have sufficient legally available funds to declare and
pay all dividends accrued at the time of such redemption, any remaining accrued
and unpaid dividends are to be added to the redemption price.

     If a preferred stock change in control, as defined in the certificate of
designations governing the Series B Preferred Stock, occurs at any time, each
holder of Series B Preferred Stock has the right to require us to purchase such
holder's Series B Preferred Stock, in whole or in part, out of legally
available funds, at a cash purchase price of 100% of their then liquidation
preference, plus accrued and unpaid dividends to the purchase date.
Additionally, in the event of a preferred stock equity offering triggering
event, which is defined in the certificate of designations governing the Series
B Preferred Stock in a manner similar to that in the Series A preferred stock,
each holder of Series B Preferred Stock has the right to require us to purchase
such holder's Series B Preferred Stock, in whole or in part, out of legally
available funds, at a cash purchase price of 100% of their liquidation
preference, plus accrued and unpaid dividends to the purchase date, but only to
the extent of any preferred stock exceeds proceeds, as defined in the
certificate of designations governing the Series B Preferred Stock, received by
us from a preferred stock equity offering triggering event.

     In the event of any liquidation, dissolution or winding up of our affairs,
whether voluntary or otherwise, after payment or provision for payment of our
debts and other liabilities, the holders of Series B Preferred Stock are
entitled to receive, out of our remaining assets, an amount equal to $100, plus
all amounts added at the end of any semi-annual dividend period for each share
of Series B Preferred Stock they hold, plus all dividends accrued and unpaid on
such share up to the date fixed for distribution, before any distribution is
made to the holders of our common stock or any other stock ranking (as to any
such distribution) junior to the Series B Preferred Stock. With regard to
rights to receive dividends, mandatory redemption payments and distributions
upon liquidation, dissolution or winding up of our affairs, the Series B
Preferred Stock ranks junior to all Series A Preferred Stock outstanding at the
time of issuance of the Series B Preferred Stock and prior to all our other
capital stock outstanding at the time it was issued.

     Except as required by law or otherwise as set forth in the certificate of
designations governing the Series B Preferred Stock, the holders of Series B
Preferred Stock do not have any voting rights or power to vote on any question
or in any proceeding or to be represented at, or to receive notice of, any
stockholders meeting. The holders of Series B Preferred Stock are entitled to
one vote per share regarding matters on which they are entitled to vote. The
Series B Preferred Stock is not convertible and has no preemptive rights.

     In case at any time (i) we fail to make a mandatory redemption of shares
of Series B Preferred Stock or (ii) we fail to comply in any material respect
with the provisions in the certificate of


                                       37




designations governing the Series B Preferred Stock relating to a preferred
stock change in control or a preferred stock equity offering triggering event,
the remedy for such matters, until cured, is that the number of members of our
board of directors is automatically increased by one and the holders of a
majority of the outstanding shares of Series B Preferred Stock are entitled, as
a class, to the exclusion of the holders of all other classes or series of our
capital stock, to elect one director to fill the directorship so created.


     The certificate of designations governing the Series B Preferred Stock
provides that, so long as any shares of the Series B Preferred Stock are
outstanding, unless the vote or consent of the holders of a greater number of
shares is then required by law, except as otherwise provided in our certificate
of incorporation, the consent of the holders of a majority of all of the
outstanding shares of Series B Preferred Stock is required for us to take
certain actions which could adversely affect holders of Series B Preferred
Stock, including to allow for the issuance of senior stock or to sell, lease or
convey all or substantially all of our assets or merge or consolidate with or
into any other entity if as a result of such transaction the Series B Preferred
Stock would be cashed out for less than 100% of their then liquidation
preference, plus any accrued and unpaid dividends.

                              DESCRIPTION OF NOTES

     You can find the definitions of certain terms used in this description
under the subheading "Certain Definitions." In this description, the word
"Metaldyne" refers only to Metaldyne Corporation and not to any of its
subsidiaries.

     Metaldyne issued the notes under an indenture among itself, the Guarantors
and The Bank of New York, as trustee, in a private transaction that was not
subject to the registration requirements of the Securities Act. See "Notice to
Investors." The terms of the notes include those stated in the indenture and
those made part of the indenture by reference to the Trust Indenture Act of
1939, as amended.

     The following description is a summary of the material provisions of the
indenture and the registration rights agreement. It does not restate those
agreements in their entirety. We urge you to read the indenture and the
registration rights agreement because they, and not this description, define
your rights as holders of the notes. Copies of the indenture and the
registration rights agreement will be available as set forth below under
"--Additional Information." Certain defined terms used in this description but
not defined below under "--Certain Definitions" have the meanings assigned to
them in the indenture.

     The registered Holder of a note will be treated as the owner of it for all
purposes. Only registered Holders will have rights under the indenture.


BRIEF DESCRIPTION OF THE NOTES AND THE GUARANTEES

The Notes

     The notes:

     o  are general unsecured obligations of Metaldyne;

     o  are subordinated in right of payment to all existing and future Senior
        Debt of Metaldyne, including under the Credit Agreement;

     o  are pari passu in right of payment with all existing and future
        unsecured senior subordinated Indebtedness of Metaldyne; and

     o  are unconditionally guaranteed by the Guarantors.

The Guarantees

     The notes are guaranteed by all of Metaldyne's Domestic Subsidiaries that
guarantee Metaldyne's Obligations under or are direct borrowers under the
Credit Agreement.

     Each guarantee of the notes:

     o  is a general unsecured obligation of the Guarantor;

     o  is subordinated in right of payment to all existing and future Senior
        Debt of that Guarantor;

     o  is pari passu in right of payment with all existing and future senior
        subordinated Indebtedness of that Guarantor; and

     o  is senior in right of payment with all existing and future Indebtedness
        of that Guarantor that is expressly subordinated in right of payment to
        the notes.

Metaldyne and the Guarantors have total Senior Debt of approximately $418
million. As indicated above and as discussed in detail below under the caption
"--Subordination," payments on the notes and under these guarantees will be
subordinated to the payment of Senior Debt. The indenture will permit us and
the Guarantors to incur additional Senior Debt.

     Not all of our subsidiaries guarantee the notes. In the event of a
bankruptcy, liquidation or reorganization of any of these Non-Guarantor
Subsidiaries, the Non-Guarantor Subsidiaries will pay the holders of their debt
and their trade creditors before they will be able to distribute any of their


                                       39




assets to us. Disregarding our receivables subsidiary, the Non-Guarantor
Subsidiaries generated approximately 19% of our consolidated net sales for the
year ended December 31, 2001. See "Risk Factors--Your right to receive payment
on the notes is junior to the right of the holders of all of our existing
senior indebtedness and possibly to all of our future borrowings."

     As of the date of the indenture, all of our Domestic Subsidiaries (other
than our receivables subsidiary) are "Restricted Subsidiaries." However, under
the circumstances described below under the subheading "--Certain
Covenants--Designation of Restricted and Unrestricted Subsidiaries," we will be
permitted to designate certain of our subsidiaries as "Unrestricted
Subsidiaries." Our Unrestricted Subsidiaries will not be subject to many of the
restrictive covenants in the indenture. Our Unrestricted Subsidiaries will not
guarantee the notes.


PRINCIPAL, MATURITY AND INTEREST

     Metaldyne issued $250,000,000 in aggregate principal amount of notes in
the offering. The indenture provides that Metaldyne may issue additional notes
thereunder from time to time after this offering. Any offering of additional
notes is subject to the covenant described below under the caption "--Certain
Covenants--Incurrence of Indebtedness and Issuance of Preferred Stock." The
notes and any additional notes subsequently issued under the indenture may be
treated as a single class for all purposes under the indenture, including,
without limitation, waivers, amendments, redemptions and offers to purchase.
Metaldyne will issue notes in denominations of $1,000 and integral multiples of
$1,000. The notes will mature on June 15, 2012.

     Interest on the notes will accrue at the rate of 11% per annum and will be
payable semi-annually in arrears on June 15 and December 15, commencing on
December 15, 2002. Metaldyne will make each interest payment to the Holders of
record on the immediately preceding June 1 and December 1.

     Interest on the notes will accrue from the date of original issuance or,
if interest has already been paid, from the date it was most recently paid.
Interest will be computed on the basis of a 360-day year comprised of twelve
30-day months.


METHODS OF RECEIVING PAYMENTS ON THE NOTES

     All payments on notes will be made at the office or agency of the paying
agent and registrar within the City and State of New York unless Metaldyne
elects to make interest payments by check mailed to the Holders at their
address set forth in the register of Holders. If a Holder has given wire
transfer instructions to Metaldyne, Metaldyne will pay all principal, interest
and premium and Liquidated Damages, if any, on that Holder's notes in
accordance with those instructions.


PAYING AGENT AND REGISTRAR FOR THE NOTES

     The trustee will initially act as paying agent and registrar. Metaldyne
may change the paying agent or registrar without prior notice to the Holders of
the notes, and Metaldyne or any of its Subsidiaries may act as paying agent or
registrar.


TRANSFER AND EXCHANGE

     A Holder may transfer or exchange notes in accordance with the indenture.
The registrar and the trustee may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents in connection with a
transfer of notes. Holders will be required to pay all taxes due on transfer.
Metaldyne is not required to transfer or exchange any note selected for
redemption. Also, Metaldyne is not required to transfer or exchange any note
for a period of 15 days before a selection of notes to be redeemed.


SUBSIDIARY GUARANTEES

     The notes are guaranteed by each of Metaldyne's current and future
Domestic Subsidiaries that are guarantors or borrowers in respect of the Credit
Agreement. These Subsidiary Guarantees are


                                       40



joint and several obligations of the Guarantors. Each Subsidiary Guarantee is
subordinated to the prior payment in full of all Senior Debt of that Guarantor.
The obligations of each Guarantor under its Subsidiary Guarantee are limited as
necessary to prevent that Subsidiary Guarantee from constituting a fraudulent
conveyance under applicable law. See "Risk Factors--Federal and state statutes
allow courts, under specific circumstances, to void guarantees and require
noteholders to return payments received from guarantors."

     A Guarantor may not sell or otherwise dispose of all or substantially all
of its assets to, or consolidate with or merge with or into (whether or not
such Guarantor is the surviving Person), another Person, other than Metaldyne
or another Guarantor, unless:

     (1)   immediately after giving effect to that transaction, no Default or
           Event of Default exists; and

     (2)   except when a release of a Subsidiary Guarantee is obtained under
           the provisions below, if, immediately after giving effect to such
           transaction, the Person acquiring the property in any such sale or
           disposition or the Person formed by or surviving any such
           consolidation or merger is a Domestic Subsidiary, such Person
           assumes all the obligations of that Guarantor under the indenture,
           its Subsidiary Guarantee and the registration rights agreement
           pursuant to a supplemental indenture satisfactory to the trustee.

     Notwithstanding the foregoing, the Subsidiary Guarantee of a Guarantor
will be released:

     (1)   in connection with any sale or other disposition of all or
           substantially all of the assets of that Guarantor (including by way
           of merger or consolidation) to a Person that is not (either before
           or after giving effect to such transaction) a Restricted Subsidiary
           of Metaldyne, if the sale or other disposition is not in violation
           with the applicable provisions of the indenture;

     (2)   in connection with any sale or other disposition of all or a
           majority of the Capital Stock of a Guarantor to a Person that is not
           Metaldyne or a Restricted Subsidiary of Metaldyne, if the sale is
           not in violation with the applicable provisions of the indenture; or

     (3)   if Metaldyne designates any Restricted Subsidiary that is a
           Guarantor as an Unrestricted Subsidiary in accordance with the
           applicable provisions of the indenture.

     See "--Repurchase at the Option of Holders--Asset Sales."


SUBORDINATION

     The payment of principal, interest and premium and Liquidated Damages, if
any, on the notes will be subordinated to the prior payment in full of all
Senior Debt of Metaldyne, including Senior Debt incurred after the date of the
indenture.

     The holders of Senior Debt will be entitled to receive payment in full of
all Obligations due in respect of Senior Debt (including interest after the
commencement of any bankruptcy proceeding at the rate specified in the
applicable Senior Debt) before the Holders of notes will be entitled to receive
any payment with respect to the notes (except that Holders of notes may receive
and retain Permitted Junior Securities and payments made from the trust
described under "--Legal Defeasance and Covenant Defeasance"), in the event of
any distribution to creditors of Metaldyne:

     (1)   in a liquidation or dissolution of Metaldyne;

     (2)   in a bankruptcy, reorganization, insolvency, receivership or similar
           proceeding relating to Metaldyne or its property;

     (3)   in an assignment for the benefit of creditors; or

     (4)   in any marshaling of Metaldyne's assets and liabilities.

     Metaldyne also may not make any payment in respect of the notes (except in
Permitted Junior Securities or from the trust described under "--Legal
Defeasance and Covenant Defeasance") if:

   (1)   a payment default on Designated Senior Debt occurs and is continuing;
         or


                                       41


     (2)   any other default occurs and is continuing on any series of
           Designated Senior Debt that permits holders of that series of
           Designated Senior Debt to accelerate its maturity and the trustee
           receives a notice of such default (a "Payment Blockage Notice") from
           Metaldyne or the holders of any Designated Senior Debt.

     Payments on the notes may and will be resumed:

     (1)   in the case of a payment default, upon the date on which such default
           is cured or waived; and

     (2)   in the case of a nonpayment default, upon the earlier of the date on
           which such nonpayment default is cured or waived or 179 days after
           the date on which the applicable Payment Blockage Notice is
           received, unless the maturity of any Designated Senior Debt has been
           accelerated.

     No new Payment Blockage Notice may be delivered unless and until:

     (1)   360 days have elapsed since the delivery of the immediately prior
           Payment Blockage Notice; and

     (2)   all scheduled payments of principal, interest and premium and
           Liquidated Damages, if any, on the notes that have come due have been
           paid in full in cash.

     No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the trustee will be, or be made, the
basis for a subsequent Payment Blockage Notice unless such default has been
cured or waived for a period of not less than 90 days.

     If the trustee or any Holder of the notes receives a payment in respect of
the notes (except in Permitted Junior Securities or from the trust described
under "--Legal Defeasance and Covenant Defeasance") when:

     (1)   the payment is prohibited by these subordination provisions; and

     (2)   the trustee or the Holder has actual knowledge that the payment is
           prohibited;

the trustee or the Holder, as the case may be, will hold the payment in trust
for the benefit of the holders of Senior Debt. Upon the proper written request
of the holders of Senior Debt, the trustee or the Holder, as the case may be,
will deliver the amounts in trust to the holders of Senior Debt or their proper
representative.

     Metaldyne must promptly notify holders of Senior Debt if payment of the
notes is accelerated because of an Event of Default.

     As a result of the subordination provisions described above, in the event
of a bankruptcy, liquidation or reorganization of Metaldyne, Holders of notes
may recover less ratably than creditors of Metaldyne who are holders of Senior
Debt. See "Risk Factors--Your right to receive payment on the notes is junior
to the right of the holders of all of our existing senior indebtedness and
possibly to all of our future borrowings."


OPTIONAL REDEMPTION

     The notes will not be subject to any redemption at the option of Metaldyne
except as set forth in the following paragraphs.

     The notes may be redeemed, in whole part or in part, at any time prior to
June 15, 2007 at the option of Metaldyne upon not less than 30 nor more than 60
days' prior notice mailed by first-class mail to each Holder's registered
address, at a redemption price equal to, as determined by the Reference
Treasury Dealer, the sum of the present values of the Remaining Scheduled
Payments discounted to the redemption date on a semi-annual basis (assuming a
360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate,
plus accrued and unpaid interest and Liquidated Damages, if any, to the
applicable date of redemption.


                                       42




     At any time prior to June 15, 2005, Metaldyne may on any one or more
occasions redeem up to 35% of the aggregate principal amount of notes issued
under the indenture at a redemption price of 111% of the principal amount, plus
accrued and unpaid interest and Liquidated Damages, if any, to the redemption
date, with the net cash proceeds of one or more Equity Offerings; provided
that:

     (1)   at least 65% of the aggregate principal amount of notes issued under
           the indenture remains outstanding immediately after the occurrence of
           such redemption (excluding notes held by Metaldyne and its
           Subsidiaries); and

     (2)   the redemption occurs within 120 days of the date of the closing of
           such Equity Offering.

     After June 15, 2007, Metaldyne may redeem all or a part of the notes upon
not less than 30 nor more than 60 days' notice, at the redemption prices
(expressed as percentages of principal amount) set forth below plus accrued and
unpaid interest and Liquidated Damages, if any, on the notes redeemed, to the
applicable redemption date, if redeemed during the twelve-month period
beginning on June 15 of the years indicated below:


YEAR                                  PERCENTAGE
- ---------------------------------   -------------
   2007 .........................       105.500%
   2008 .........................       103.667%
   2009 .........................       101.833%
   2010 and thereafter ..........       100.000%


MANDATORY REDEMPTION

     Metaldyne is not required to make mandatory redemption or sinking fund
payments with respect to the notes.


REPURCHASE AT THE OPTION OF HOLDERS

Change of Control

     If a Change of Control occurs, each Holder of notes will have the right to
require Metaldyne to repurchase all or any part (equal to $1,000 or an integral
multiple of $1,000) of that Holder's notes pursuant to a Change of Control
Offer on the terms set forth in the indenture. In the Change of Control Offer,
Metaldyne will offer a Change of Control Payment in cash equal to 101% of the
aggregate principal amount of notes repurchased plus accrued and unpaid
interest and Liquidated Damages, if any, on the notes repurchased, to the date
of purchase. Within 15 days following any Change of Control, Metaldyne will
mail a notice to each Holder describing the transaction or transactions that
constitute the Change of Control and offering to repurchase notes on the Change
of Control Payment Date specified in the notice, which date will be no earlier
than 30 days and no later than 60 days from the date such notice is mailed,
pursuant to the procedures required by the indenture and described in such
notice. Metaldyne will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with the
repurchase of the notes as a result of a Change of Control. To the extent that
the provisions of any securities laws or regulations conflict with the Change
of Control provisions of the indenture, Metaldyne will comply with the
applicable securities laws and regulations and will not be deemed to have
breached its obligations under the Change of Control provisions of the
indenture by virtue of such conflict.

     On the Change of Control Payment Date, Metaldyne will, to the extent
lawful:

     (1)   accept for payment all notes or portions of notes properly tendered
           pursuant to the Change of Control Offer;

     (2)   deposit with the paying agent an amount equal to the Change of
           Control Payment in respect of all notes or portions of notes properly
           tendered; and


                                       43



     (3)   deliver or cause to be delivered to the trustee the notes properly
           accepted together with an officers' certificate stating the aggregate
           principal amount of notes or portions of notes being purchased by
           Metaldyne.

     The paying agent will promptly mail to each Holder of notes properly
tendered the Change of Control Payment for such notes, and the trustee will
promptly authenticate and mail (or cause to be transferred by book entry) to
each Holder a new note equal in principal amount to any unpurchased portion of
the notes surrendered, if any; provided that each new note will be in a
principal amount of $1,000 or an integral multiple of $1,000.

     Prior to complying with any of the provisions of this "Change of Control"
covenant, but in any event within 90 days following a Change of Control,
Metaldyne will either repay all outstanding Senior Debt or obtain the requisite
consents, if any, under all agreements governing outstanding Senior Debt to
permit the repurchase of notes required by this covenant. Metaldyne will
publicly announce the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Payment Date.

     The provisions described above that require Metaldyne to make a Change of
Control Offer following a Change of Control will be applicable whether or not
any other provisions of the indenture are applicable. Except as described above
with respect to a Change of Control, the indenture does not contain provisions
that permit the Holders of the notes to require that Metaldyne repurchase or
redeem the notes in the event of a takeover, recapitalization or similar
transaction.

     Metaldyne will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set
forth in the indenture applicable to a Change of Control Offer made by
Metaldyne and purchases all notes properly tendered and not withdrawn under the
Change of Control Offer. Alternatively, Metaldyne may assign all or part of its
obligations to purchase all notes validly tendered and not properly withdrawn
under a Change of Control Offer to a third party. In the event of such an
assignment, Metaldyne shall be released from its obligations to purchase the
notes as to which the assignment relates subject to the third party purchasing
such notes. A Change of Control Offer may be made in advance of a Change of
Control, and conditioned upon such Change of Control if a definitive agreement
is in place for the Change of Control at the time of making of the Change of
Control Offer. Notes repurchased by Metaldyne pursuant to a Change of Control
Offer will have the status of notes issued but not outstanding or will be
retired and canceled, at the option of Metaldyne. Notes purchased by a third
party upon assignment will have the status of note issued and outstanding.

     The Credit Agreement provides that certain change of control events with
respect to Metaldyne constitute an event of default thereunder. In the event
that at the time of such Change of Control the terms of the Credit Agreement
restrict or prohibit the repurchase of notes pursuant to this covenant, then
prior to the mailing of the Change of Control Offer but in any event within 30
days following any Change of Control, Metaldyne would need to (i) repay in full
all Indebtedness under the Credit Agreement or (ii) obtain the requisite
consent under the Credit Facilities to permit the repurchase of the notes as
provided for in this covenant.

     Future Indebtedness of Metaldyne and the Restricted Subsidiaries may
contain prohibitions of certain events that would constitute a Change of
Control or require such Indebtedness to be repurchased upon a Change of
Control. A Change of Control would also constitute a termination event in
respect of our receivables facility. Moreover, the exercise by the Holders of
notes of their right to require Metaldyne to repurchase the notes could cause a
default under such Indebtedness, even if the Change of Control itself does not,
due to the financial effect of such repurchase. Finally, Metaldyne's ability to
pay cash to the Holders of notes upon a repurchase may be limited by
Metaldyne's then existing financial resources. There can be no assurance that
sufficient funds will be available when necessary to make any required
repurchases. See "Risk Factors--We may be prevented from financing, or may be
unable to raise funds necessary to finance, the change of control offer
required by the indenture."


                                       44




     The definition of Change of Control includes a phrase relating to the
direct or indirect sale, lease, transfer, conveyance or other disposition of
"all or substantially all" of the properties or assets of Metaldyne and its
Subsidiaries taken as a whole. Although there is a limited body of case law
interpreting the phrase "substantially all," there is no precise established
definition of the phrase under applicable law. Accordingly, the ability of a
Holder of notes to require Metaldyne to repurchase its notes as a result of a
sale, lease, transfer, conveyance or other disposition of less than all of the
assets of Metaldyne and its Subsidiaries taken as a whole to another Person or
group may be uncertain.

Asset Sales

     Metaldyne will not, and will not permit any of the Restricted Subsidiaries
to, consummate an Asset Sale unless:

     (1)   Metaldyne (or the Restricted Subsidiary, as the case may be) receives
           consideration at the time of the Asset Sale at least equal to the
           fair market value of the assets or Equity Interests issued or sold
           or otherwise disposed of;

     (2)   the fair market value is determined by Metaldyne's Board of Directors
           and evidenced by a resolution of the Board of Directors set forth in
           an officers' certificate delivered to the trustee; and

     (3)    either (a) at least 75% of the consideration received in the Asset
            Sale by Metaldyne or such Restricted Subsidiary is in the form of
            cash or (b) the aggregate non-cash consideration for all Asset Sales
            not meeting the criteria set forth in the preceding clause (a) does
            not exceed a fair market value in excess of $20.0 million. For
            purposes of this provision, each of the following will be deemed to
            be cash:

            (a)   any liabilities, as shown on Metaldyne's or such Restricted
                  Subsidiary's most recent consolidated balance sheet, of
                  Metaldyne or any Restricted Subsidiary (other than contingent
                  liabilities and liabilities that are by their terms
                  subordinated to the notes or any Subsidiary Guarantee) that
                  are assumed by the transferee of any such assets pursuant to
                  a customary novation agreement that releases Metaldyne or
                  such Restricted Subsidiary from further liability; and

            (b)   any securities, notes or other obligations received by
                  Metaldyne or any such Restricted Subsidiary from such
                  transferee to the extent within 60 days, subject to ordinary
                  settlement periods, they are converted by Metaldyne or such
                  Restricted Subsidiary into cash.

     Within 365 days after the receipt of any Net Proceeds from an Asset Sale,
Metaldyne may apply those Net Proceeds at its option:

     (1)   to permanently repay Indebtedness (other than Indebtedness that is
           by its terms subordinated to, or pari passu with, the notes or any
           Subsidiary Guarantee) of Metaldyne or any Restricted Subsidiary,
           including any Obligations under a Credit Facility and, if the
           Indebtedness repaid is revolving credit Indebtedness, to
           correspondingly reduce commitments with respect thereto or to reduce
           receivables advances and reduce commitments in respect of a
           Receivables Facility;

     (2)   to acquire assets of, or a majority of the Voting Stock of, any
           person owning assets used or usable in a business of Metaldyne and
           the Restricted Subsidiaries; or

     (3)   to make a capital expenditure.

     Pending the final application of any Net Proceeds, Metaldyne may
temporarily reduce revolving credit borrowings or otherwise invest or use the
Net Proceeds in any manner that is not prohibited by the indenture.

     Any Net Proceeds from Asset Sales that are not applied or invested as
provided in the preceding paragraph (other than Net Proceeds from the sale of
the common stock of TriMas after the date of


                                       45




the indenture) will constitute "Excess Proceeds." When the aggregate amount of
Excess Proceeds exceeds $25.0 million, Metaldyne will make an Asset Sale Offer
to all Holders of notes and all holders of other Indebtedness that is pari
passu with the notes containing provisions similar to those set forth in the
indenture with respect to offers to purchase or redeem with the proceeds of
sales of assets to purchase the maximum principal amount of notes and such
other pari passu Indebtedness that may be purchased out of the Excess Proceeds.
The offer price in any Asset Sale Offer will be equal to 100% of principal
amount plus accrued and unpaid interest and Liquidated Damages, if any, to the
date of purchase, and will be payable in cash. If any Excess Proceeds remain
after consummation of an Asset Sale Offer, Metaldyne may use those Excess
Proceeds for any purpose not otherwise prohibited by the indenture. If the
aggregate principal amount of notes and other pari passu Indebtedness tendered
into such Asset Sale Offer exceeds the amount of Excess Proceeds, the trustee
will select the notes and such other pari passu Indebtedness to be purchased on
a pro rata basis. Upon completion of each Asset Sale Offer, the amount of
Excess Proceeds will be reset at zero.

     Metaldyne will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with each
repurchase of notes pursuant to an Asset Sale Offer. To the extent that the
provisions of any securities laws or regulations conflict with the Asset Sale
provisions of the indenture, Metaldyne will comply with the applicable
securities laws and regulations and will not be deemed to have breached its
obligations under the Asset Sale provisions of the indenture by virtue of such
conflict.

     The agreements governing Metaldyne's outstanding Senior Debt currently
prohibit Metaldyne from purchasing any notes, and also provides that certain
change of control or asset sale events with respect to Metaldyne would
constitute a default under these agreements. Any future credit agreements or
other agreements relating to Senior Debt to which Metaldyne becomes a party may
contain similar restrictions and provisions. In the event a Change of Control
or Asset Sale occurs at a time when Metaldyne is prohibited from purchasing
notes, Metaldyne could seek the consent of its senior lenders to the purchase
of notes or could attempt to refinance the borrowings that contain such
prohibition. If Metaldyne does not obtain such a consent or repay such
borrowings, Metaldyne will remain prohibited from purchasing notes. In such
case, Metaldyne's failure to purchase tendered notes would constitute an Event
of Default under the indenture which would, in turn, constitute a default under
such Senior Debt. In such circumstances, the subordination provisions in the
indenture would likely restrict payments to the Holders of notes.

Selection and Notice

     If less than all of the notes are to be redeemed at any time, the trustee
will select notes for redemption as follows:

     (1)   if the notes are listed on any national securities exchange, in
           compliance with the requirements of the principal national securities
           exchange on which the notes are listed; or

     (2)   if the notes are not listed on any national securities exchange, on a
           pro rata basis, by lot or by such method as the trustee deems fair
           and appropriate.

     No notes of $1,000 or less can be redeemed in part. Notices of redemption
will be mailed by first class mail at least 30 but not more than 60 days before
the redemption date to each Holder of notes to be redeemed at its registered
address, except that redemption notices may be mailed more than 60 days prior
to a redemption date if the notice is issued in connection with a defeasance of
the notes or a satisfaction and discharge of the indenture. Notices of
redemption may not be conditional.

     If any note is to be redeemed in part only, the notice of redemption that
relates to that note will state the portion of the principal amount of that
note that is to be redeemed. A new note in principal amount equal to the
unredeemed portion of the original note will be issued in the name of the
Holder of notes upon cancellation of the original note. Notes called for
redemption become due on the date fixed for redemption. On and after the
redemption date, interest ceases to accrue on notes or portions of them called
for redemption.


                                       46




CERTAIN COVENANTS

Restricted Payments

     Metaldyne will not, and will not permit any of the Restricted Subsidiaries
to, directly or indirectly:

     (1)    declare or pay any dividend or make any other payment or
            distribution on account of Metaldyne's Equity Interests (including,
            without limitation, any payment in connection with any merger or
            consolidation involving Metaldyne or any of its Restricted
            Subsidiaries) or to the direct or indirect holders of Metaldyne's
            Equity Interests in their capacity as such (other than dividends or
            distributions payable in Equity Interests (other than Disqualified
            Stock) of Metaldyne or to Metaldyne or a Restricted Subsidiary of
            Metaldyne);

     (2)    purchase, redeem or otherwise acquire or retire for value
            (including, without limitation, in connection with any merger or
            consolidation involving Metaldyne) any Equity Interests of
            Metaldyne;

     (3)    purchase, redeem, defease or otherwise acquire or retire for value
            any Indebtedness that is subordinated to the notes or the Subsidiary
            Guarantees, except a purchase, redemption, defeasance or other
            acquisition or retirement for value in anticipation of satisfying a
            sinking fund obligation, principal installment or final maturity, in
            each case due within one year of the date of such acquisition or
            retirement; or

     (4)    make any Restricted Investment

(all such payments and other actions set forth in these clauses (1) through (4)
above being collectively referred to as "Restricted Payments"), unless, at the
time of and after giving effect to such Restricted Payment:

     (1)    no Default or Event of Default has occurred and is continuing or
            would occur as a consequence of such Restricted Payment;

     (2)    Metaldyne would, after giving pro forma effect thereto as if such
            Restricted Payment had been made at the beginning of the applicable
            four-quarter period, have been permitted to incur at least $1.00 of
            additional Indebtedness pursuant to the Fixed Charge Coverage Ratio
            test set forth in the first paragraph of the covenant described
            below under the caption "--Incurrence of Indebtedness and Issuance
            of Preferred Stock"; and

     (3)    such Restricted Payment, together with the aggregate amount of all
            other Restricted Payments made by Metaldyne and the Restricted
            Subsidiaries after the date of the indenture (excluding Restricted
            Payments permitted by clauses (2), (3), (4), (8), (9) and, to the
            extent reducing Consolidated Net Income, (10) of the next succeeding
            paragraph), is less than the sum, without duplication, of:

            (a)   50% of the Consolidated Net Income of Metaldyne for the
                  period (taken as one accounting period) from June 30, 2002 to
                  the end of Metaldyne's most recently ended fiscal quarter for
                  which internal financial statements are available at the time
                  of such Restricted Payment (or, if such Consolidated Net
                  Income for such period is a deficit, less 100% of such
                  deficit), plus

            (b)   100% of the aggregate net proceeds received by Metaldyne
                  since the date of the indenture, including the fair market
                  value of property other than cash (determined in good faith
                  by the Board of Directors), as a contribution to its common
                  equity capital or from the issue or sale of Equity Interests
                  of Metaldyne (other than Disqualified Stock) or from the
                  issue or sale of convertible or exchangeable Disqualified
                  Stock or convertible or exchangeable debt securities of
                  Metaldyne that have been converted into or exchanged for such
                  Equity Interests (other than Equity Interests (or
                  Disqualified Stock or debt securities) sold to a Subsidiary
                  of Metaldyne), provided, that (1) any such net proceeds
                  received, directly or indirectly, by Metaldyne from an
                  employee stock


                                       47




                  ownership plan financed by loans from Metaldyne or a
                  Subsidiary of Metaldyne shall be included only to the extent
                  such loans have been repaid with cash on or prior to the date
                  of determination and (2) any net proceeds received in a form
                  other than cash (other than on conversion or in exchange for a
                  security issued for cash to the extent of the cash received)
                  from a person that is an Affiliate of Metaldyne prior to such
                  receipt shall be excluded from this clause (3)(b); plus

           (c)    the amount by which Indebtedness of Metaldyne or any
                  Restricted Subsidiary is reduced on Metaldyne's balance sheet
                  upon the conversion or exchange (other than by a Restricted
                  Subsidiary) subsequent to the date of the indenture of any
                  Indebtedness of Metaldyne or any Restricted Subsidiary into
                  Capital Stock (other than Redeemable Stock) of Metaldyne
                  (less the amount of any cash or other property (other than
                  such Capital Stock) distributed by Metaldyne or any
                  Restricted Subsidiary upon such conversion or exchange); plus


           (d)    to the extent that any Restricted Investment that was made
                  after the date of the indenture is sold for cash or otherwise
                  liquidated or repaid for cash, the lesser of (i) the cash
                  return of capital with respect to such Restricted Investment
                  (less the cost of disposition, if any) and (ii) the initial
                  amount of such Restricted Investment; plus

           (e)    to the extent that any Unrestricted Subsidiary of Metaldyne
                  is redesignated as a Restricted Subsidiary after the date of
                  the indenture, the lesser of (i) the fair market value of
                  Metaldyne's Investment in such Subsidiary as of the date of
                  such redesignation or (ii) such fair market value as of the
                  date on which such Subsidiary was originally designated as an
                  Unrestricted Subsidiary.

     So long as no Default has occurred and is continuing or would be caused
thereby (except as to clauses (1) through (4), (6), (9), (10), (11) and (12)
below), the preceding provisions will not prohibit:

     (1)   the payment of any dividend within 60 days after the date of
           declaration of the dividend, if at the date of declaration the
           dividend payment would have complied with the provisions of the
           indenture;

     (2)   the redemption, repurchase, retirement, defeasance or other
           acquisition of any subordinated Indebtedness of Metaldyne or any
           Guarantor or of any Equity Interests of Metaldyne in exchange for,
           or out of the net cash proceeds of the substantially concurrent sale
           (other than to a Restricted Subsidiary) of, Equity Interests (other
           than Disqualified Stock) of Metaldyne or a substantially concurrent
           capital contribution to Metaldyne; provided that the amount of any
           such net cash proceeds that are utilized for any such redemption,
           repurchase, retirement, defeasance or other acquisition will be
           excluded from clause (3)(b) of the preceding paragraph;

     (3)   the defeasance, redemption, repurchase or other acquisition of
           subordinated Indebtedness of Metaldyne or any Guarantor in exchange
           for, or with the net cash proceeds from, an incurrence of Permitted
           Refinancing Indebtedness or other Indebtedness Incurred under the
           first paragraph of the covenant "Incurrence of Indebtedness and
           Issuance of Preferred Stock";

     (4)   the defeasance, redemption, repurchase or other acquisition of
           subordinated Indebtedness from Net Proceeds to the extent not

           redemption shall be excluded from the calculation of the amount
           available for Restricted Payments pursuant to the preceding
           paragraph;


     (5)    the defeasance, redemption, repurchase or other acquisition of
            subordinated Indebtedness or Disqualified Stock of Metaldyne or any
            Guarantor following a Change of Control after Metaldyne shall have
            complied with the provisions under "--Change of Control," including
            payment of the applicable Change of Control Payment;


                                       48



     (6)    the repurchase, redemption or other acquisition or retirement for
            value of any Equity Interests of Metaldyne held by any member of
            Metaldyne's (or any of its Subsidiaries') management pursuant to any
            management equity subscription agreement, stock option agreement or

            owners of a business acquired by Metaldyne or former employees of
            Metaldyne or any of its Subsidiaries and, in either case, acquired
            in connection with a sale of a business to Metaldyne; provided that
            the aggregate price paid for all such repurchased, redeemed,
            acquired or retired Equity Interests may not exceed $7.5 million in
            any twelve-month period plus any unutilized portion of such amount
            in any prior fiscal year;

     (7)    any Investment made by the exchange for, or out of the proceeds of,
            a capital contribution in respect of or the substantially concurrent
            sale of, Capital Stock (other than Disqualified Stock) of Metaldyne
            to the extent the net cash proceeds thereof are received by
            Metaldyne, provided, that the amount of such capital contribution or
            proceeds used to make such Investment shall be excluded from the
            calculation of the amount available for Restricted Payments pursuant
            to the preceding paragraph;

            restricted stock awards of Metaldyne;

     (10)   the repurchase, redemption or other acquisition or retirement of
            Existing Preferred Stock; provided, that the aggregate amount of

            since the date of the indenture;

     (11)   Restricted Investments in an aggregate amount not to exceed the net

            Subsidiaries (calculated on an after-tax basis) from the sale of
            common stock of TriMas owned by the Company and its Restricted
            Subsidiaries after the date of the indenture (after giving effect to

     (12)   the payment of the Saturn Proceeds under the Recapitalization
            Agreement.

     The amount of all Restricted Payments (other than cash) will be the fair
market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by Metaldyne or such Restricted
Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair
market value of any assets or securities that are required to be valued by this
covenant will be determined by the Board of Directors acting in good faith
whose resolution with respect thereto will be conclusive. Any payments
hereunder shall be calculated net of amounts for which Metaldyne or any
Restricted Subsidiary is reimbursed under the Stock Purchase Agreement.

Incurrence of Indebtedness and Issuance of Preferred Stock

     Metaldyne will not, and will not permit any of the Restricted Subsidiaries
to, directly or indirectly, create, incur, issue, assume, guarantee or
otherwise become directly or indirectly liable, contingently or otherwise, with
respect to (collectively, "incur") any Indebtedness (including Acquired Debt),
and Metaldyne will not issue any Disqualified Stock and will not permit any
Restricted Subsidiary that is not a Guarantor to issue any shares of preferred
stock; provided, however, that Metaldyne may incur Indebtedness (including
Acquired Debt) or issue Disqualified Stock, and the Restricted Subsidiaries may
incur Indebtedness or Restricted Subsidiaries that are not Guarantors may issue
preferred stock, if the Fixed Charge Coverage Ratio for Metaldyne's most
recently ended four full fiscal quarters for which financial statements are
available immediately preceding the date on which such additional Indebtedness
is incurred or such Disqualified Stock or preferred stock is issued would have
been at least 2.25 to 1.0, determined on a pro forma basis (including a pro
forma application of the net proceeds therefrom), as if the additional
Indebtedness had been incurred or the preferred stock or Disqualified Stock had
been issued, as the case may be, at the beginning of such four-quarter period.


                                       49




     The first paragraph of this covenant will not prohibit the incurrence of
any of the following items of Indebtedness (collectively, "Permitted Debt"):

     (1)   (a)    the incurrence by Metaldyne and any Restricted Subsidiary
                  of Indebtedness and letters of credit under the revolving
                  facility component of the Credit Facilities in an aggregate
                  principal amount at any one time outstanding under this
                  clause (1)(a) (with letters of credit being deemed to have
                  a principal amount equal to the maximum potential liability
                  of Metaldyne and its Subsidiaries thereunder) not to exceed
                  $250.0 million; and

           (b)    the incurrence by Metaldyne and any Restricted Subsidiary of
                  Indebtedness under the term loan components of the Credit
                  Facilities in an aggregate principal amount at any one time
                  outstanding under this clause (1)(b) not to exceed the amount
                  outstanding on the date of issuance of the notes (it being
                  understood that the $400.0 million replacement term loans
                  anticipated on the issuance date are permitted), after giving
                  effect to the actual use of proceeds from the issuance of the
                  notes, less the aggregate amount of all Net Proceeds of Asset
                  Sales applied by Metaldyne or any of the Restricted
                  Subsidiaries to repay the principal of any term Indebtedness
                  under a Credit Facility since the date of the indenture; and

           (c)    the incurrence of Indebtedness of Metaldyne or any Restricted
                  Subsidiary under one or more receivables financing facilities
                  pursuant to which Metaldyne or any Restricted Subsidiary
                  pledges or otherwise borrows against its Receivables in an
                  aggregate principal amount which, when taken together with
                  all other Indebtedness Incurred pursuant to this clause (c)
                  and then outstanding, does not exceed 85% of the consolidated
                  book value of the Receivables of Metaldyne and the Restricted
                  Subsidiaries (to the extent such Receivables or any other
                  Receivables of Metaldyne or such Restricted Subsidiary, as
                  the case may be, are not then being financed pursuant to a
                  Qualified Receivables Transaction or as a basis for
                  Indebtedness Incurred pursuant to clause (10) of this
                  paragraph);

     (2)   the incurrence by Metaldyne and the Restricted Subsidiaries of the
           Existing Indebtedness;

     (3)   the incurrence by Metaldyne and the Guarantors of Indebtedness
           represented by the notes and the related Subsidiary Guarantees to be

           related Subsidiary Guarantees to be issued pursuant to the
           registration rights agreement;

     (4)   the incurrence by Metaldyne or any of its Subsidiaries of
           Indebtedness represented by Capital Lease Obligations, mortgage
           financings or purchase money obligations, in each case, incurred for
           the purpose of financing all or any part of the purchase price or
           cost of construction or improvement of property, plant or equipment
           used in the business of Metaldyne or such Restricted Subsidiary
           ("Capital Spending") and incurred no later than 270 days after the
           date of such acquisition or the date of completion of such
           construction or improvement, provided, that the principal amount of
           any Indebtedness incurred pursuant to this clause (4) (other than
           Permitted Refinancing Indebtedness) at any time during a single
           fiscal year shall not exceed 30% of the total Capital Spending of
           Metaldyne and the Restricted Subsidiaries made during the period of
           the most recently completed four consecutive fiscal quarters prior
           to the date of such incurrence;

     (5)   the incurrence by Metaldyne or any of the Restricted Subsidiaries of
           Permitted Refinancing Indebtedness in exchange for, or the net
           proceeds of which are used to refund, refinance or replace
           Indebtedness (other than intercompany Indebtedness) that was
           permitted by the indenture to be incurred under the first paragraph
           of this covenant or clauses (2), (3), (4), (5), (8), (9) or (15) of
           this paragraph;

     (6)   the incurrence by Metaldyne or any of the Restricted Subsidiaries of
           intercompany Indebtedness between or among Metaldyne and any of the
           Restricted Subsidiaries; provided, however, that:


                                       50




           (a)    if Metaldyne or any Guarantor is the obligor on such
                  Indebtedness, such Indebtedness must be (i) unsecured and
                  (ii) if the obligee is neither Metaldyne nor a Guarantor,
                  expressly subordinated to the prior payment in full in cash
                  of all Obligations with respect to the notes (in the case of
                  Metaldyne) (or the Subsidiary Guarantee, in the case of a
                  Guarantor); and

           (b)    (i) any subsequent issuance or transfer of Equity Interests
                  that results in any such Indebtedness being held by a Person
                  other than Metaldyne or a Restricted Subsidiary of Metaldyne
                  and (ii) any sale or other transfer of any such Indebtedness
                  to a Person that is not either Metaldyne or a Restricted
                  Subsidiary of Metaldyne will be deemed, in each case, to
                  constitute an incurrence of such Indebtedness by Metaldyne or
                  such Restricted Subsidiary, as the case may be, that was not
                  permitted by this clause (6);

     (7)   the incurrence by Metaldyne or any of the Restricted Subsidiaries of
           Hedging Obligations that are incurred for the purpose of hedging (i)
           interest rate risk or the impact of interest rate fluctuations on
           Metaldyne or any of the Restricted Subsidiaries and (ii) in the case
           of currency or commodity protection agreements, against currency
           exchange rate or commodity price fluctuations in the ordinary course
           of Metaldyne and the Restricted Subsidiaries' respective businesses
           and, in the case of both (i) and (ii), not for purposes of
           speculation;

     (8)   the guarantee by Metaldyne or any of the Guarantors of Indebtedness
           of Metaldyne or a Restricted Subsidiary that was permitted to be
           incurred by another provision of this covenant;

     (9)   the accrual of interest, the accretion or amortization of original
           issue discount, the payment of interest on any Indebtedness in the
           form of additional Indebtedness with the same terms, and the payment
           of dividends on Disqualified Stock in the form of additional shares
           of similar Disqualified Stock will not be deemed to be an incurrence
           of Indebtedness or an issuance of Disqualified Stock for purposes of
           this covenant; provided, in each such case, that the amount thereof
           is included in Fixed Charges of Metaldyne as accrued;

     (10)  Indebtedness of Foreign Subsidiaries incurred for working capital
           purposes if, at the time of incurrence of such Indebtedness, and
           after giving effect thereto, the aggregate principal amount of all
           Indebtedness of the Foreign Subsidiaries incurred pursuant to this
           clause (10) and then outstanding does not exceed the amount equal to
           the sum of (x) 80% of the consolidated book value of the accounts
           receivable of the Foreign Subsidiaries and (y) 60% of the
           consolidated book value of the inventories of the Foreign

           course of business, (b) in respect of performance bonds or similar
           obligations of Metaldyne or any of the Restricted Subsidiaries for
           or in connection with pledges, deposits or payments made or given in
           the ordinary course of business and not for money borrowed in
           connection with or to secure statutory, regulatory or similar
           obligations, including obligations under health, safety or
           environmental obligations, and (c) arising from guarantees to
           suppliers, lessors, licensees, contractors, franchises or customers
           of obligations incurred in the ordinary course of business and not
           for money borrowed;

     (12)  Indebtedness arising from agreements of Metaldyne or a Restricted
           Subsidiary providing for indemnification, adjustment of purchase

           connection with the disposition of any business, assets or Capital
           Stock of a Restricted Subsidiary, provided, that the maximum
           aggregate liability in respect of all such Indebtedness shall at no
           time exceed the gross proceeds actually received by Metaldyne and
           the Restricted Subsidiaries in connection with such disposition;


                                       51




     (13)  Indebtedness arising from the honoring by a bank or other financial
           institution of a check, draft or similar instrument (except in the
           case of daylight overdrafts) drawn against insufficient funds in the
           ordinary course of business, provided, however, that such
           Indebtedness is extinguished within five Business Days of
           incurrence;

     (14)  the incurrence by a Receivables Subsidiary of Indebtedness in a
           Qualified Receivables Transaction that is without recourse to
           Metaldyne or to any other Subsidiary of Metaldyne or their assets
           (other than such Receivables Subsidiary and its assets and, as to
           Metaldyne or any Subsidiary of Metaldyne, other than pursuant to
           representations, warranties, covenants and indemnities customary for
           such transactions) and is not guaranteed by any such Person;

     (15)  the issuance and sale of preferred stock (a) by a Foreign Subsidiary
           in lieu of the issuance of non-voting common stock if (i) the laws
           of the jurisdiction of incorporation of such Subsidiary precludes
           the issuance of non-voting common stock and (ii) the preferential
           rights afforded to the holders of such preferred stock are limited
           to those customarily provided for in such jurisdiction in respect of
           the issuance of non-voting stock, (b) by a Restricted Subsidiary
           which is a joint venture with a third party which is not an
           Affiliate of the Company or a Restricted Subsidiary, and (c) by a
           Restricted Subsidiary pursuant to obligations with respect to the
           issuance or sale of Preferred Stock which exist at the time such
           Person becomes a Restricted Subsidiary and which were not created in
           connection with or in contemplation of such Person becoming a
           Restricted Subsidiary; and

     (16)  the incurrence by Metaldyne or any of the Restricted Subsidiaries of
           additional Indebtedness in an aggregate principal amount (or
           accreted value, as applicable) at any time outstanding, including
           all Permitted Refinancing Indebtedness, incurred to refund,
           refinance or replace any Indebtedness incurred pursuant to this
           clause (16), not to exceed $35.0 million.

     For purposes of determining compliance with this "Incurrence of
Indebtedness and Issuance of Preferred Stock" covenant, in the event that an
item of proposed Indebtedness meets the criteria of more than one of the
categories of Permitted Debt described in clauses (1) through (16) above, or is
entitled to be incurred pursuant to the first paragraph of this covenant,
Metaldyne will be permitted to classify such item of Indebtedness on the date
of its incurrence, or later reclassify all or a portion of such item of
Indebtedness, in any manner that complies with this covenant. Indebtedness
under Credit Facilities outstanding on the date on which notes are first issued
and authenticated under the indenture will be deemed to have been incurred on
such date in reliance on the exception provided by clauses (1) and (2) of the
definition of Permitted Debt.

     For purposes of determining compliance with any U.S. dollar-denominated
restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent
principal amount of Indebtedness denominated in a foreign currency shall be
calculated based on the relevant currency exchange rate in effect on the date
such Indebtedness was incurred, in the case of term Indebtedness, or first
committed, in the case of revolving credit Indebtedness; provided, that if such
Indebtedness is incurred to Refinance other Indebtedness denominated in a
foreign currency, and such Refinancing would cause the applicable U.S.
dollar-denominated restriction to be exceeded if calculated at the relevant
currency exchange rate in effect on the date of such Refinancing, such U.S.
dollar-denominated restriction shall be deemed not to have been exceeded so
long as the principal amount of such Refinancing Indebtedness does not exceed
the principal amount of such Indebtedness being Refinanced. Notwithstanding any
other provision of this covenant, the maximum amount of Indebtedness that
Metaldyne may incur pursuant to this covenant shall not be deemed to be
exceeded solely as a result of fluctuations in the exchange rate of currencies.
The principal amount of any Indebtedness incurred to Refinance other
Indebtedness, if incurred in a different currency from the Indebtedness being
Refinanced, shall be calculated based on the currency exchange rate applicable
to the currencies in which such Refinancing Indebtedness is denominated that is
in effect on the date of such Refinancing.

Anti-Layering

     Metaldyne will not incur, create, issue, assume, guarantee or otherwise
become liable for any Indebtedness that is subordinate or junior in right of
payment to any Senior Debt of Metaldyne and


                                       52



senior in any respect in right of payment to the notes. No Guarantor will
incur, create, issue, assume, guarantee or otherwise become liable for any
Indebtedness that is subordinate or junior in right of payment to the Senior
Debt of such Guarantor and senior in any respect in right of payment to such
Guarantor's Subsidiary Guarantee. The foregoing shall not affect the
Subordinated Debentures outstanding on the date of the indenture.

Liens

     Metaldyne will not and will not permit any of the Restricted Subsidiaries
to, directly or indirectly, create, incur, assume or otherwise cause or suffer
to exist or become effective any Lien of any kind securing Indebtedness (other
than Permitted Liens) upon any of their property or assets, now owned or
hereafter acquired to secure any Indebtedness without making, or causing such
Subsidiary to make, effective provision for securing the notes or, in respect
of Liens on any Guarantor's property or assets, any Guarantee of such
Guarantor, (x) equally and ratably with such Indebtedness as to such property
or assets for so long as such Indebtedness will be so secured or (y) in the
event such Indebtedness is subordinated Indebtedness, prior to such
Indebtedness as to such property or assets for so long as such Indebtedness
will be so secured.

Dividend and Other Payment Restrictions Affecting Subsidiaries

     Metaldyne will not, and will not permit any of the Restricted Subsidiaries
to, directly or indirectly, create or permit to exist or become effective any
consensual encumbrance or restriction on the ability of any Restricted
Subsidiary to:

     (1)   pay dividends or make any other distributions on its Capital
           Stock to Metaldyne or any of the Restricted Subsidiaries, or with
           respect to any other interest or participation in, or measured by,
           its profits, or pay any indebtedness owed to Metaldyne or any of the
           Restricted Subsidiaries;

     (2)   make loans or advances to Metaldyne or any of the Restricted
           Subsidiaries; or

     (3)   transfer any of its properties or assets to Metaldyne or any of the
           Restricted Subsidiaries.

     However, the preceding restrictions will not apply to encumbrances or
restrictions existing under or by reason of:

     (1)   agreements governing Existing Indebtedness and Credit Facilities as
           in effect on the date of the indenture and any amendments,
           modifications, restatements, renewals, increases, supplements,
           refundings, replacements or refinancings of those agreements,
           provided that the amendments, modifications, restatements, renewals,
           increases, supplements, refundings, replacement or refinancings are
           no more restrictive, taken as a whole, with respect to such dividend
           and other payment restrictions than those contained in those

           contained in the agreements governing such Permitted Refinancing

           contained in the agreements governing the Indebtedness being
           Refinanced;


                                       53

           such date and not incurred in anticipation of becoming a Subsidiary
           and not incurred to provide all or any portion of the funds utilized

     (13)  restrictions on cash or other deposits or net worth imposed by
           customers under contracts entered into in the ordinary course of
           business.

Merger, Consolidation or Sale of Assets

     Metaldyne may not, directly or indirectly: (1) consolidate or merge with
or into another Person (whether or not Metaldyne is the surviving corporation);
or (2) sell, assign, transfer, convey or otherwise dispose of all or
substantially all of the properties or assets of Metaldyne and the Restricted
Subsidiaries taken as a whole, in one or more related transactions, to another
Person; unless:

     (1)   either: (a) Metaldyne is the surviving corporation; or (b) the
           Person formed by or surviving any such consolidation or merger (if
           other than Metaldyne) or to which such sale, assignment, transfer,
           conveyance or other disposition has been made is a corporation
           organized or existing under the laws of the United States, any state
           of the United States or the District of Columbia;

           assumes all the obligations of Metaldyne under the notes, the
           indenture and the registration rights agreement pursuant to
           agreements reasonably satisfactory to the trustee;

     (3)   immediately after such transaction, no Default or Event of Default
           exists; and

     (4)   Metaldyne or the Person formed by or surviving any such
           consolidation or merger (if other than Metaldyne), or to which such
           sale, assignment, transfer, conveyance or other disposition has been
           made will, on the date of such transaction after giving pro forma
           effect thereto and any related financing transactions as if the same
           had occurred at the beginning of the applicable four-quarter period,
           be permitted to incur at least $1.00 of additional Indebtedness
           pursuant to the Fixed Charge Coverage Ratio test set forth in the
           first paragraph of the covenant described above under the caption
           "--Incurrence of Indebtedness and Issuance of Preferred Stock."


                                       54



     In addition, Metaldyne may not, directly or indirectly, lease all or
substantially all of its properties or assets, in one or more related
transactions, to any other Person. This "Merger, Consolidation or Sale of
Assets" covenant will not apply to a sale, assignment, transfer, conveyance or
other disposition of assets between or among Metaldyne and any of the
Guarantors.

     Notwithstanding anything in the indenture:

     (a)      a Restricted Subsidiary may consolidate with, merge into or
              convey, lease, sell, assign, transfer or otherwise dispose of all
              or part of its properties and assets to Metaldyne or a Restricted
              Subsidiary; and

     (b)      Metaldyne may merge with an Affiliate incorporated solely for
              the purpose of reincorporating Metaldyne in another jurisdiction
              in the United States to realize tax or other benefits.

Transactions with Affiliates

     Metaldyne will not, and will not permit any of the Restricted Subsidiaries
to, make any payment to, or sell, lease, transfer or otherwise dispose of any
of its properties or assets to, or purchase any property or assets from, or
enter into or make or amend any transaction, contract, agreement,
understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate (each, an "Affiliate Transaction"), unless:

     (1)   the Affiliate Transaction is on terms that are not materially less
           favorable, taken as a whole, to Metaldyne or the relevant Restricted
           Subsidiary than those that would have been obtained at the time in a
           comparable transaction by Metaldyne or such Restricted Subsidiary
           with an unaffiliated Person; and

     (2)   Metaldyne delivers to the trustee:

           (a)    except when the opinion referred to in the following clause
                  (b) is delivered, with respect to any Affiliate Transaction
                  or series of related Affiliate Transactions involving
                  aggregate consideration in excess of $5.0 million, a
                  resolution of the Board of Directors set forth in an
                  officers' certificate certifying that such Affiliate
                  Transaction complies with this covenant and that such
                  Affiliate Transaction has been approved by a majority of the
                  disinterested members of the Board of Directors; and

           (b)    with respect to any Affiliate Transaction or series of
                  related Affiliate Transactions involving aggregate
                  consideration in excess of $25.0 million, an opinion as to
                  the fairness to Metaldyne of such Affiliate Transaction from
                  a financial point of view issued by an accounting, appraisal
                  or investment banking firm of national standing.

     The following items will not be deemed to be Affiliate Transactions and,
therefore, will not be subject to the provisions of the prior paragraph:

     (1)    loans or advances to employees, indemnification agreements with and
            the payment of fees and indemnities to directors, officers and
            full-time employees of Metaldyne and the Restricted Subsidiaries and
            employment, non-competition or confidentiality agreements entered
            into with any such person in the ordinary course of business;

     (2)    any issuance of securities, or other payments, awards or grants in
            cash, securities or otherwise pursuant to, or the funding of,
            employment, compensation or indemnification arrangements, stock
            options and stock ownership plans in the ordinary course of business
            to or with officers, directors or employees of Metaldyne and the
            Restricted Subsidiaries, or approved by the Board of Directors;

     (3)    transactions between or among Metaldyne and/or the Restricted
            Subsidiaries;

     (4)    transactions with a Person that is an Affiliate of Metaldyne solely
            because Metaldyne owns an Equity Interest in, or controls, such
            Person;


                                       55




     (5)   transactions pursuant to agreements existing on the date of the
           indenture, including, without limitation, the Stock Purchase
           Agreement, the Shareholders Agreement, the TriMas Shareholders
           Agreement and the TriMas Corporate Services Agreement, and, in each
           case, any amendment or supplement thereto that, taken in its
           entirety, is no less favorable to Metaldyne than such agreement as
           in effect on the date of the indenture;

     (6)   sales of Equity Interests (other than Disqualified Stock) of
           Metaldyne to Affiliates of Metaldyne or the receipt of capital
           contributions by Metaldyne;

     (7)   payment of certain fees under the Advisory Agreement;

     (8)   transactions (in connection with a Qualified Receivables Transaction)
           between or among Metaldyne and/or its Restricted Subsidiaries or
           transactions between a Receivables Subsidiary and any Person in which
           the Receivables Subsidiary has an Investment;

     (9)   any management, service, purchase, lease, supply or similar agreement
           entered into in the ordinary course of Metaldyne's business between
           Metaldyne or any Restricted Subsidiary and any Unrestricted
           Subsidiary or any Affiliate, so long as Metaldyne determines in good
           faith (which determination shall be conclusive) that any such
           agreement is on terms no less favorable to Metaldyne or such
           Restricted Subsidiary than those that could be obtained in a
           comparable arm's-length transaction with an entity that is not an
           Affiliate; and

     (10)  Restricted Payments and Permitted Investments that are permitted by
           the provisions of the indenture described above under the caption
           "--Restricted Payments."

Additional Subsidiary Guarantees

     After the Issue Date, Metaldyne will cause each Restricted Subsidiary,
other than a Subsidiary which is a Subsidiary Guarantor, that becomes a
guarantor or other obligor with respect to the obligations of Metaldyne or a
Domestic Restricted Subsidiary under the Credit Agreement to execute and
deliver to the trustee a Guarantee pursuant to which such Guarantor will
unconditionally Guarantee, on a joint and several basis, the full and prompt
payment of the principal of, premium, if any, and interest on the notes on a
senior subordinated basis.

Designation of Restricted and Unrestricted Subsidiaries

     The Board of Directors may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if that designation would not cause a Default. If a
Restricted Subsidiary is designated as an Unrestricted Subsidiary, the
aggregate fair market value of all outstanding Investments owned by Metaldyne
and the Restricted Subsidiaries in the Subsidiary properly designated will be
deemed to be an Investment made as of the time of the designation and will
reduce the amount available for Restricted Payments under the first paragraph
of the covenant described above under the caption "--Restricted Payments" or
Permitted Investments, as determined by Metaldyne. That designation will only
be permitted if the Investment would be permitted at that time and if the
Restricted Subsidiary otherwise meets the definition of an Unrestricted
Subsidiary. The Board of Directors may redesignate any Unrestricted Subsidiary
to be a Restricted Subsidiary if the redesignation would not cause a Default.

Reports

     Whether or not required by the rules and regulations of the SEC, so long
as any notes are outstanding, Metaldyne will furnish to the Holders of notes,
within the time periods specified in the SEC's rules and regulations:

     (1)   all quarterly and annual financial information that would be
           required to be contained in a filing with the SEC on Forms 10-Q and
           10-K if Metaldyne were required to file such Forms, including a
           "Management's Discussion and Analysis of Financial Condition and
           Results of Operations" and, with respect to the annual information
           only, a report on the annual financial statements by Metaldyne's
           certified independent accountants; and


                                       56



     (2)   all current reports that would be required to be filed with the SEC
           on Form 8-K if Metaldyne were required to file such reports.

     In addition, whether or not required by the SEC, Metaldyne will file a
copy of all of the information and reports referred to in clauses (1) and (2)
above with the SEC for public availability within the time periods specified in
the SEC's rules and regulations (unless the SEC will not accept such a filing)
and make such information available to securities analysts and prospective
investors upon request. In addition, Metaldyne and the Guarantors have agreed
that, for so long as any notes remain outstanding, they will furnish to the
Holders and to securities analysts and prospective investors, upon their
request, the information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act.


EVENTS OF DEFAULT AND REMEDIES

     Each of the following is an Event of Default:

     (1)   default for 30 days in the payment when due of interest on, or
           Liquidated Damages with respect to, the notes whether or not
           prohibited by the subordination provisions of the indenture;

     (2)   default in payment when due of the principal of, or premium, if any,
           on the notes whether or not prohibited by the subordination
           provisions of the indenture;

     (3)   failure by Metaldyne or any of its Subsidiaries to comply with the
           provisions described under the captions "--Repurchase at the Option
           of Holders--Change of Control" or "--Certain Covenants--Merger,
           Consolidation or Sale of Assets" after written notice to Metaldyne
           by the Trustee or the holders of at least 25% in aggregate principal
           amount of the outstanding Notes;

     (4)   failure by Metaldyne or any of its Subsidiaries to comply with any
           of the other agreements in the indenture continued for 60 days after
           written notice to Metaldyne by the Trustee or the holders of at
           least 25% in aggregate principal amount of the outstanding Notes;

     (5)   default under any mortgage, indenture or instrument under which
           there may be issued or by which there may be secured or evidenced
           any Indebtedness for money borrowed by Metaldyne or any of the
           Restricted Subsidiaries (or the payment of which is guaranteed by
           Metaldyne or any of the Restricted Subsidiaries) whether such
           Indebtedness or guarantee now exists, or is created after the date
           of the indenture, if that default:

           (a)    is caused by a failure to pay principal of such Indebtedness
                  at the final maturity thereof (a "Payment Default"); or

           (b)    results in the acceleration of such Indebtedness prior to its
                  express maturity,

           and, in each case, the principal amount of any such Indebtedness,
           together with the principal amount of any other such Indebtedness
           under which there has been a Payment Default or the maturity of
           which has been so accelerated, aggregates $20.0 million or more;

     (6)   failure by Metaldyne or any of the Restricted Subsidiaries to pay
           final judgments aggregating in excess of $20.0 million (net of any
           insurance proceeds available to pay such judgment), which judgments
           are not paid, discharged or stayed for a period of 60 days;

     (7)   except as permitted by the indenture, any Subsidiary Guarantee shall
           be held in any judicial proceeding to be unenforceable or invalid or
           shall cease for any reason to be in full force and effect or any
           Guarantor, or any Person acting on behalf of any Guarantor, shall
           deny or disaffirm its obligations under its Subsidiary Guarantee;
           and

     (8)   certain events of bankruptcy or insolvency described in the indenture
           with respect to Metaldyne or any of the Significant Subsidiaries
           thereof.


                                       57



     In the case of an Event of Default arising from certain events of
bankruptcy or insolvency, with respect to Metaldyne, all outstanding notes will
become due and payable immediately without further action or notice. If any
other Event of Default occurs and is continuing, the trustee or the Holders of
at least 25% in principal amount of the then outstanding notes may declare all
the notes to be due and payable immediately by giving notice in writing to us
and the trustee specifying the respective Event of Default (the "Acceleration
Notice") or if there are any amounts outstanding under the Credit Agreement, it
shall become immediately due and payable upon the first to occur of an
acceleration under the Credit Agreement or five business days after receipt by
us and the administrative agent under the Credit Agreement of such Acceleration
Notice (but only if such Event of Default is then continuing).

     Holders of the notes may not enforce the indenture or the notes except as
provided in the indenture. Subject to certain limitations, Holders of a
majority in principal amount of the then outstanding notes may direct the
trustee in its exercise of any trust or power. The trustee may withhold from
Holders of the notes notice of any continuing Default or Event of Default if it
determines that withholding notes is in their interest, except a Default or
Event of Default relating to the payment of principal or interest or Liquidated
Damages.

     The Holders of a majority in aggregate principal amount of the notes then
outstanding by notice to the trustee may on behalf of the Holders of all of the
notes waive any existing Default or Event of Default and its consequences under
the indenture except a continuing Default or Event of Default in the payment of
interest or Liquidated Damages on, or the principal of, the notes.

     In the event of a declaration of acceleration of the notes because an
Event of Default described in clause (5) under "Events of Default" has occurred
and is continuing, the declaration of acceleration of the notes shall be
automatically annulled if the event of default or payment default triggering
such Event of Default pursuant to clause (5) shall be remedied or cured by
Metaldyne or a Restricted Subsidiary or waived by the holders of the relevant
Indebtedness within 60 days after the declaration of acceleration with respect
thereto and if (a) the annulment of the acceleration of the notes would not
conflict with any judgment or decree of a court of competent jurisdiction and
(b) all existing Events of Default, except nonpayment of principal, premium or
interest on the notes that became due solely because of the acceleration of the
notes, have been cured or waived.

     Metaldyne is required to deliver to the trustee annually a statement
regarding compliance with the indenture. Upon becoming aware of any Default or
Event of Default, Metaldyne is required to deliver to the trustee a statement
specifying such Default or Event of Default.


NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS

     No director, officer, employee, incorporator or stockholder of Metaldyne
or any Guarantor, as such, will have any liability for any obligations of
Metaldyne or the Guarantors under the notes, the indenture, the Subsidiary
Guarantees, or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder of notes by accepting a note waives
and releases all such liability. The waiver and release are part of the
consideration for issuance of the notes. The waiver may not be effective to
waive liabilities under the federal securities laws.


LEGAL DEFEASANCE AND COVENANT DEFEASANCE

     Metaldyne may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding notes and all
obligations of the Guarantors discharged with respect to their Subsidiary
Guarantees ("Legal Defeasance") except for:

     (1)   the rights of Holders of outstanding notes to receive payments in
           respect of the principal of, or interest or premium and Liquidated
           Damages, if any, on such notes when such payments are due from the
           trust referred to below;

     (2)   Metaldyne's obligations with respect to the notes concerning issuing
           temporary notes, registration of notes, mutilated, destroyed, lost or
           stolen notes and the maintenance of an office or agency for payment
           and money for security payments held in trust;


                                       58




     (3)   the rights, powers, trusts, duties and immunities of the trustee, and
           Metaldyne's and the Guarantor's obligations in connection therewith;
           and

     (4)   the Legal Defeasance provisions of the indenture.

     In addition, Metaldyne may, at its option and at any time, elect to have
the obligations of Metaldyne and the Guarantors released with respect to
certain covenants that are described in the indenture ("Covenant Defeasance")
and thereafter any omission to comply with those covenants will not constitute
a Default or Event of Default with respect to the notes. In the event Covenant
Defeasance occurs, certain events (not including non-payment, bankruptcy,
receivership, rehabilitation and insolvency events) described under "--Events
of Default and Remedies" will no longer constitute an Event of Default with
respect to the notes.

     In order to exercise either Legal Defeasance or Covenant Defeasance:

     (1)   Metaldyne must irrevocably deposit with the trustee, in trust, for
           the benefit of the Holders of the notes, cash in U.S. dollars,
           non-callable Government Securities, or a combination of cash in U.S.
           dollars and non-callable Government Securities, in amounts as will be
           sufficient, in the opinion of a nationally recognized firm of
           independent public accountants, to pay the principal of, or interest
           and premium and Liquidated Damages, if any, on the outstanding notes
           on the stated maturity or on the applicable redemption date, as the
           case may be, and Metaldyne must specify whether the notes are being
           defeased to maturity or to a particular redemption date;

     (2)   in the case of Legal Defeasance, Metaldyne has delivered to the
           trustee an opinion of counsel reasonably acceptable to the trustee
           confirming that (a) Metaldyne has received from, or there has been
           published by, the Internal Revenue Service a ruling or (b) since the
           date of the indenture, there has been a change in the applicable
           federal income tax law, in either case to the effect that, and based
           thereon such opinion of counsel will confirm that, the Holders of the
           outstanding notes will not recognize income, gain or loss for federal
           income tax purposes as a result of such Legal Defeasance and will be
           subject to federal income tax on the same amounts, in the same manner
           and at the same times as would have been the case if such Legal
           Defeasance had not occurred;

     (3)   in the case of Covenant Defeasance, Metaldyne has delivered to the
           trustee an opinion of counsel reasonably acceptable to the trustee
           confirming that the Holders of the outstanding notes will not
           recognize income, gain or loss for federal income tax purposes as a
           result of such Covenant Defeasance and will be subject to federal
           income tax on the same amounts, in the same manner and at the same
           times as would have been the case if such Covenant Defeasance had not
           occurred;

     (4)   no Default or Event of Default has occurred and is continuing on the
           date of such deposit (other than a Default or Event of Default
           resulting from the borrowing of funds to be applied to such deposit);

     (5)   such Legal Defeasance or Covenant Defeasance will not result in a
           breach or violation of, or constitute a default under any material
           agreement or instrument (other than the indenture) to which Metaldyne
           or any of its Subsidiaries is a party or by which Metaldyne or any of
           its Subsidiaries is bound;

     (6)   Metaldyne must deliver to the trustee an officers' certificate
           stating that the deposit was not made by Metaldyne with the intent of
           preferring the Holders of notes over the other creditors of Metaldyne

           creditors of Metaldyne or others; and

                                       59




     In the event that Metaldyne exercises its legal defeasance option or
covenant defeasance option, each of the Guarantors will be released from all of
its obligations with respect to its guarantee. Metaldyne may exercise its legal
defeasance option notwithstanding its prior exercise of the covenant defeasance
option.

     Except as provided in the next two succeeding paragraphs, the indenture or
the notes may be amended or supplemented with the consent of the Holders of at
least a majority in principal amount of the notes then outstanding (including,
without limitation, consents obtained in connection with a purchase of, or
tender offer or exchange offer for, notes), and any existing default or

     Without the consent of each Holder affected, an amendment or waiver may

           amendment, supplement or waiver;

           waiver of the payment default that resulted from such acceleration);

     (5)   make any note payable in money other than that stated in the notes;

     (6)   make any change in the provisions of the indenture relating to
           waivers of past Defaults or the rights of Holders of notes to

           Liquidated Damages, if any, on the notes;

     (7)   waive a redemption payment with respect to any note (other than a

           caption "--Repurchase at the Option of Holders"); or

     (8)   make any change in the preceding amendment and waiver provisions.

     In addition, any amendment to, or waiver of, the provisions of the
indenture relating to subordination that adversely affects the rights of the
Holders of the notes will require the consent of the Holders of at least 75% in

     Notwithstanding the preceding, without the consent of any Holder of notes,
Metaldyne, the Guarantors and the trustee may amend or supplement the indenture
or the notes:

           substantially all of Metaldyne's assets;

     (4)   to make any change that would provide any additional rights or
           benefits to the Holders of notes or that does not adversely affect
           the legal rights under the indenture of any such Holder; or


                                       60




     (5)   to comply with requirements of the SEC in order to effect or maintain
           the qualification of the indenture under the Trust Indenture Act.

to all notes issued thereunder, when:

     (1)   either:

           (a)    all notes that have been authenticated, except lost, stolen
                  or destroyed notes that have been replaced or paid and notes
                  for whose payment money has been deposited in trust and
                  thereafter repaid to Metaldyne, have been delivered to the
                  trustee for cancellation; or

           (b)    all notes that have not been delivered to the trustee for
                  cancellation have become due and payable by reason of the
                  mailing of a notice of redemption or otherwise or will become
                  due and payable within one year and Metaldyne or any
                  Guarantor has irrevocably deposited or caused to be deposited
                  with the trustee as trust funds in trust solely for the
                  benefit of the Holders, cash in U.S. dollars, non-callable
                  Government Securities, or a combination of cash in U.S.
                  dollars and non-callable Government Securities, in amounts as
                  will be sufficient without consideration of any reinvestment
                  of interest, to pay and discharge the entire indebtedness on
                  the notes not delivered to the trustee for cancellation for
                  principal, premium and Liquidated Damages, if any, and
                  accrued interest to the date of maturity or redemption;

     (2)   no Default or Event of Default has occurred and is continuing on the
           date of the deposit or will occur as a result of the deposit and the
           deposit will not result in a breach or violation of, or constitute a
           default under, any other instrument to which Metaldyne or any
           Guarantor is a party or by which Metaldyne or any Guarantor is
           bound;

     (3)   Metaldyne or any Guarantor has paid or caused to be paid all sums
           payable by it under the indenture; and

     (4)   Metaldyne has delivered irrevocable instructions to the trustee under
           the indenture to apply the deposited money toward the payment of the
           notes at maturity or a redemption date, as the case may be.

     In addition, Metaldyne must deliver an officers' certificate and an
opinion of counsel to the trustee stating that all conditions precedent to
satisfaction and discharge have been satisfied.


CONCERNING THE TRUSTEE

     If the trustee becomes a creditor of Metaldyne or any Guarantor, the
indenture limits its right to obtain payment of claims in certain cases, or to
realize on certain property received in respect of any such claim as security
or otherwise. The trustee will be permitted to engage in other transactions;
however, if it acquires any conflicting interest it must eliminate such
conflict within 90 days, apply to the SEC for permission to continue or resign.

     The Holders of a majority in principal amount of the then outstanding
notes will have the right to direct the time, method and place of conducting
any proceeding for exercising any remedy available to the trustee, subject to
certain exceptions. The indenture provides that in case an Event of Default
occurs and is continuing, the trustee will be required, in the exercise of its
power, to use the degree of care of a prudent man in the conduct of his own
affairs. Subject to such provisions, the trustee will be under no obligation to
exercise any of its rights or powers under the indenture at the request of any
Holder of notes, unless such Holder has offered to the trustee security and
indemnity satisfactory to it against any loss, liability or expense.
