  This summary may not contain all the information that may be important in
deciding whether to purchase Common Stock. If you are considering purchasing
Common Stock you should carefully review the information contained in this
Prospectus Supplement, the accompanying Prospectus and the documents to which
they refer before you make an investment decision. Federal-Mogul Corporation is
referred to in this Prospectus Supplement and in the accompanying Prospectus as
"Federal-Mogul" and "the Company."
 
                           FEDERAL-MOGUL CORPORATION
 
  Federal-Mogul is a leading global manufacturer and distributor of a broad
range of engine components, other vehicular components and related products.
The Company's products are primarily used in the manufacture and maintenance
of:
 
  . automobiles and light trucks
 
  . heavy duty trucks
 
  . farm and construction vehicles and
 
  . industrial equipment.
 
  Federal-Mogul's products include:
 
  POWERTRAIN SYSTEM COMPONENTS, which are internal engine components, directly
involved in creating a vehicle's movement. These components consist primarily
of engine bearings, bushings, pistons, piston pins, rings, liners and ignition.
 
  SEALING SYSTEM COMPONENTS, which provide for the encapsulation of fluids and
gases from the engine, transmission and axle and also prevent external objects
from entering the systems. They consist of dynamic seals (which are found
between components that move in relation to one another) and gaskets (which are
located between components that are static in relation to one another).
 
  BRAKES AND FRICTION PRODUCTS, which are used primarily for vehicular brake
systems. The acquisition of Cooper Automotive substantially expanded Federal-
Mogul's existing brakes and friction business and management anticipates
establishing brakes and friction products (previously administered together
with the products listed under "general products") as a separate manufacturing
operating unit.
 
  GENERAL PRODUCTS, which consist of Federal-Mogul's remaining product lines,
primarily camshafts, sintered products (which are engine components made from
powdered metal), chassis components and systems protection products (which are
used for shielding against heat, noise, abrasion and stone impingement).
 
  Federal-Mogul markets its products to many of the world's major manufacturers
of new vehicles ("original equipment manufacturers"). Federal-Mogul also
manufactures and supplies its products and related parts to aftermarket
customers (purchasers of replacement parts) for each category of equipment
described above. Among Federal-Mogul's largest customers are BMW, Caterpillar,
Cummins, DaimlerChrysler, Fiat, Ford, General Motors, LucasVarity, NAPA,
Peugeot, Renault and Volkswagen/Audi (in alphabetical order).
 
  Founded in 1899, Federal-Mogul traditionally focused on the manufacture and
distribution of engine bearings and sealing systems. From 1990 through 1996,
Federal-Mogul pursued a strategy of opening retail auto parts stores in various
domestic and international locations. These geographically dispersed stores
proved burdensome to manage and resulted in substantial operating losses. In
the fourth quarter of 1996, Federal-Mogul underwent a change of management,
following which the Company initiated a significant restructuring program
 
 
                                      S-3
<PAGE>
 
designed to refocus the Company on its core competency of manufacturing. As
part of its restructuring, Federal-Mogul closed or sold substantially all of
its retail operations. Federal-Mogul also began to pursue a growth strategy of
acquiring complementary manufacturing companies that enhance the Company's
product base, expand its global manufacturing operations and provide
opportunities to capitalize on the Company's aftermarket distribution network
and technological resources.
 
  In connection with its growth strategy, on March 6, 1998 Federal-Mogul
acquired T&N plc ("T&N"), a U.K.-based supplier of engine and transmission
products, for a total purchase price of approximately (Pounds)1.46 billion
($2.41 billion, converted at a blended exchange rate of 1 pound sterling to
1.6510 U.S. dollars). T&N manufactures and supplies high technology engineered
automotive components and industrial materials including pistons, friction
products, bearings, systems protection, camshafts and sealing products. On
February 24, 1998, Federal-Mogul acquired Fel-Pro Incorporated and certain
affiliated entities, which constitute the operating businesses of the Fel-Pro
group of companies ("Fel-Pro"), a privately-owned automotive parts
manufacturer, for total consideration of approximately $717 million. Fel-Pro is
a premier gasket manufacturer for the North American aftermarket and original
equipment heavy duty market. See "Recent Acquisitions."
 
                              RECENT DEVELOPMENTS
 
  On October 9, 1998, the Company acquired the automotive division of Cooper
Industries, Inc. ("Cooper Automotive") for $1.9 billion (the "Cooper
Acquisition"), excluding fees and expenses. Cooper Automotive, comprised of the
Cooper Automotive and the Moog divisions of Cooper Industries, Inc., is a
premier provider of leading brand name automotive products to the aftermarket
and original equipment market. Cooper Automotive manufactures and distributes
brake and friction products, chassis, ignition products and lighting and wiper
products under well-known brand names including Champion, Moog, Abex, Wagner
and Zanxx. Among Cooper Automotive's largest customers are AutoValue, Carquest,
DaimlerChrysler, Ford, Fiat, General Motors and NAPA (in alphabetical order).
Cooper Automotive had revenues in 1997 of $1.9 billion.
 
  Following the Cooper Acquisition, Federal-Mogul operates facilities at over
300 locations in 24 countries. On a pro forma basis adjusted for the
acquisitions of T&N, Fel-Pro and Cooper Automotive and the dispositions of the
T&N Bearings Business and the Fel-Pro Chemical Business (each as defined
below), as if they had occurred on January 1, 1997, Federal-Mogul's total sales
for 1997 were $6.6 billion. More detailed information regarding the Cooper
Acquisition and its effect upon the Company is found under the captions
"Unaudited Pro Forma Financial Data: T&N, Fel-Pro and Cooper Automotive" and
"Recent Acquisitions," and in Annex I to this Prospectus Supplement.
 
  On October 27, 1998, Federal-Mogul entered into an agreement to sell T&N's
thinwall and dry bearings (polymer bearings) operations (the "T&N Bearings
Business") and certain other engine hard part assets to Dana Corporation for a
purchase price of $430 million. Completion of the sale is subject to regulatory
approval and is expected to occur by the end of 1998.

                               BUSINESS STRATEGY
 
  Federal-Mogul's recent restructuring program and the acquisitions which
followed focused the Company on its core competency of manufacturing and
expanded the Company's product base, geographic reach and market penetration.
Key elements of the Company's strategy for continuing this focused growth and
further enhancing its market presence are as follows:
 
  . Systems Approach. Due to its broad manufacturing capabilities and product
    offerings, Federal-Mogul is one of a small number of manufacturers with
    the ability to seal entire engine, transmission and axle systems and to
    act as a single-source supplier of engine and sealing components. In
    addition, Federal-Mogul is committed to becoming a provider of complete
    engine modules for its original equipment customers. The Company believes
    that original equipment manufacturers of automobiles, trucks and other
    vehicles are increasingly seeking to reduce the number of suppliers from
    which they source parts and to develop relationships with suppliers that
    can offer integrated systems and modules in order to lower production
    costs, increase quality, provide better technology and shorten product
    development cycles. The T&N and Fel-Pro acquisitions expanded the
    Company's gasket, cast aluminum piston, large bearing and sealing product
    lines and added product lines for articulated pistons, cylinder liners
    and piston rings. These acquisitions are major steps toward Federal-
    Mogul's strategic goal of developing global engine and sealing systems
    for its original equipment customers. The Cooper Acquisition expands the
    Company's friction and brake components, ignition and lighting product
    lines and adds to the Company's system capabilities primarily in the
    brake/friction, lighting and ignition areas.
 
  . Continue Focus on New Product Innovation. The Company's expertise in
    engineering and research and development has made it a leader in
    virtually all of the product segments in which it competes. The Company
    utilizes the latest technologies, processes and materials to solve
    problems for customers and to bring new, innovative products to market.
    The Company has special competencies in alloy development, customized
    materials formulations, surface technology, advanced modeling and testing
    and systems engineering. These capabilities allow the Company to reduce
    production costs and to develop products that are more durable and
    exhibit better interaction with surrounding components. These innovative
    products better serve original equipment customers and aid brand
    development, resulting in a higher margin product mix.
 
  . Extend Global Manufacturing Reach. The Company intends to extend its
    manufacturing capabilities worldwide in response to the global expansion
    of its original equipment manufacturing customers. The acquisitions of
    T&N, Fel-Pro and Cooper Automotive substantially increased the Company's
    manufacturing presence, particularly in North America and Europe.
    Management believes expansion of manufacturing operations to follow the
    expansion of original equipment manufacturers into Latin America, Eastern
    Europe and Asia provides significant growth opportunities for the Company
    in the future.
 
  . Pursue Strategic Acquisitions. The vehicular engine and sealing component
    industry is large and highly fragmented. The Company believes that as
    original equipment manufacturers continue to outsource and reduce the
    number of suppliers, opportunities will exist for further consolidation
    within this industry. The Company believes that, through its established
    presence in these markets and its strong relationships with original
    equipment manufacturers worldwide, the Company is in a favorable position
    to capitalize on future industry consolidation. The Company's management
    has substantial experience in completing and integrating acquisitions
    within the automobile parts industry and believes that this experience
    will help it select and pursue acquisition opportunities that can enhance
    the Company's product base, expand its global manufacturing operations
    and further capitalize on the Company's aftermarket distribution network
    and technological resources.
 
  . Expand Aftermarket Presence. Approximately 48% of the Company's 1997
    sales, on a pro forma basis adjusted for the acquisitions of T&N and Fel-
    Pro, were generated from the aftermarket. The Company
 
                                      S-6
<PAGE>
 
   believes that opportunities exist to further leverage its broad product
   offerings and to increase its penetration of the worldwide aftermarket. In
   addition, the Company believes that its ability to sell products developed
   for the original equipment market to aftermarket customers reduces the
   impact of adverse changes in demand for new vehicles. The Cooper
   Acquisition substantially expands the Company's presence in the worldwide
   aftermarket. On a pro forma basis, giving effect to the acquisitions of
   T&N, Fel-Pro and Cooper Automotive and the dispositions of the T&N
   Bearings Business and the Fel-Pro Chemical Business as if they had
   occurred on January 1, 1997, approximately 55% of the Company's 1997 sales
   were generated from the aftermarket.
 
  . EVA Focus. In 1997, Federal-Mogul adopted Economic Value Added (EVA(R))
    as its primary system for evaluating financial performance (for purposes
    including planning, internal resource allocation and, to an increasing
    extent, determining incentive compensation). EVA is based upon comparison
    of the cost of capital with the return on such capital. EVA is equal to
    net operating profits after economic taxes less a charge for capital
    invested in the Company. This charge is equal to the product of the total
    capital invested in the Company and the targeted weighted average cost of
    capital. In connection with this effort, the Company's management places
    significant emphasis on improving the Company's financial performance and
    achieving various operating efficiencies through technical development,
    manufacturing, marketing and administrative rationalization. The
    Company's EVA improved significantly in 1997 due primarily to improved
    operating margins (which margins rose from 4.9% in 1996 to 7.7% in 1997)
    combined with $166 million of cash flow from continuing operations (net
    of expenditures for property, plant and equipment) in 1997. The Company
    is also applying EVA to the integration of T&N, Fel-Pro and Cooper
    Automotive to optimize synergies and cost savings. As the Company
    continues to expand both its product base and its geographic scope,
    management will evaluate investments and acquisitions based on both EVA
    and strategic importance. In addition, the Company currently determines
    compensation for certain top managers using an EVA based system and
    expects to increase the number of managers participating in its EVA based
    compensation system to over 200 in 1999.

SUMMARY UNAUDITED PRO FORMA FINANCIAL DATA
 
  The following table presents summary pro forma financial information for the
periods indicated and on September 30, 1998, prepared on the following bases:
(i) as adjusted to give effect to the acquisitions of T&N and Fel-Pro, the
dispositions of the T&N Bearings Business and the Fel-Pro Chemical Business,
and the June Equity Offering, as if they had occurred at the beginning of each
period for which information is presented and on September 30, 1998, and (ii)
as adjusted for the factors in clause (i), and as further adjusted to give
effect to the Cooper Acquisition and the Offerings as if they had occurred at
the beginning of each period for which information is presented and on
September 30, 1998. This summary pro forma financial data is taken from the
"Unaudited Pro Forma Financial Data" included elsewhere in this Prospectus
Supplement.
 
  The unaudited pro forma financial information is presented for illustrative
purposes only and is not necessarily indicative of the financial position or
results of operations that would have occurred had the relevant events happened
on the dates indicated, nor are they necessarily indicative of Federal-Mogul's
future results of operations or financial position. The unaudited pro forma
financial information does not include expected synergies, cost benefits and
related restructuring charges in connection with the acquisitions of T&N, Fel-
Pro and Cooper Automotive. Because the information in this table is only a
summary and does not provide all of the information contained in the related
financial statements, prospective investors in the Common Stock should read
this table together with "Unaudited Pro Forma Financial Data" herein and the
financial statements and other information which Federal-Mogul has filed with
the Securities and Exchange Commission. See "Available Information."
 
  The unaudited pro forma financial information gives effect to the
acquisitions using the purchase method of accounting. The pro forma adjustments
are described in the accompanying notes to the unaudited pro forma financial
information and are based upon preliminary available information and upon
certain assumptions made by management of Federal-Mogul. Accordingly, the pro
forma adjustments reflected in the unaudited pro forma financial information
are preliminary and subject to revision. Such revision could be material.

(1) Summary pro forma financial information is as adjusted to give effect to
    the following: (i) the acquisitions of T&N and Fel-Pro, the dispositions of
    the T&N Bearings Business and the Fel-Pro Chemical Business, and the June
    Equity Offering, (ii) the Cooper Acquisition, and (iii) the sale by the
    Company of 14.0 million shares of Common Stock in the Offerings at a
    purchase price of $56 15/16 per share, in each case as if these events had
    each occurred at the beginning of each period for which information is
    presented and on September 30, 1998. See "Use of Proceeds."
(2) The unaudited pro forma statements of operations include only the results
    of ongoing operations and exclude such impacts as extraordinary items,
    nonrecurring items relating directly to the acquisitions, synergies and
    expected cost benefits associated with the integration of the acquisitions.
    See "Management's Discussion and Analysis of Financial Condition and
    Results of Operations" and "Recent Acquisitions."
(3) Earnings (loss) per share as calculated for the pro forma combined entity
    includes a decrease to net earnings of $7.0 million and $2.7 million in
    preferred dividend requirements for the year ended December 31, 1997 and
    the nine months ended September 30, 1998, respectively.
(4) "EBITDA" represents the sum of income before interest income and expense,
    expense associated with the Company-obligated mandatorily redeemable

    items, plus depreciation and amortization as well as nonrecurring items
    including gains on the sale of businesses, restructuring and reengineering
    charges, adjustments of assets held for sale to fair value and other long
    lived assets, the net effect of British pound currency option and forward
    contract, gains associated with options over shares in Kolbenschmidt AG,
    bid costs and nonrecurring charges of Cooper Automotive. EBITDA should not
    be construed as a substitute for income from operations, net income or cash
    flow operating activities, for the purpose of analyzing Federal-Mogul's
    operating performance, financial position and cash flows. EBITDA measures
    are calculated differently by other companies. As such, the EBITDA measures

                                 RISK FACTORS
 
  An investment in Common Stock involves various risks. If you are considering
purchasing Common Stock, you should carefully review the information contained
in this Prospectus Supplement, the accompanying Prospectus and the documents
to which they refer. You should particularly consider the following factors:
 
EFFECT OF SUBSTANTIAL LEVERAGE
 
  Federal-Mogul incurred a significant amount of debt when it purchased T&N,
Fel-Pro and Cooper Automotive. The Company will use the net proceeds of the
Offerings to repay a portion of this debt, but the Company will continue to be
highly leveraged. The following chart contains important financial statistics
as of September 30, 1998, adjusted to account for the Cooper Acquisition as if
it had been completed by that date:
 
<TABLE>
         <S>                                    <C>
           Total short-term debt............... $  173.8 million
           Total long-term debt................ $4,352.6 million
         Total debt............................ $4,526.4 million
           Company-obligated mandatorily
            redeemable preferred securities of
            subsidiary trust holding solely
            convertible subordinated debentures
            of the Company..................... $  575.0 million
           Minority interest in consolidated
            subsidiaries....................... $   62.4 million
           Shareholders' equity................ $1,205.6 million
         Total capitalization.................. $6,369.4 million
</TABLE>
 
  This means that as of September 30, 1998, accounting for the Cooper
Acquisition as if it had been completed by that date:
 
    . the Company's ratio of debt to total capitalization was 71%; and
 
    . the Company's ratio of long-term debt to total capitalization was 68%.
 
  Federal-Mogul intends to use the net proceeds of the Offerings to repay
approximately $773.6 million of its existing bank debt ($889.7 million if the
Underwriters' overallotment options are exercised in full). In addition,
Federal-Mogul has signed an agreement to sell the T&N Bearings Business for
$430 million. The Company will use the proceeds received from this sale, after
deducting taxes, to repay indebtedness. However, because the sale has not yet
been completed, the Company cannot be certain of the net proceeds it will
receive.
 
  Federal-Mogul's leverage may have important consequences to holders of the
Common Stock. For example, it could:
 
    . limit Federal-Mogul's ability to obtain additional financing to fund
       future working capital requirements, capital expenditures, debt
       service requirements, acquisitions or other general corporate
       requirements;
 
    . require Federal-Mogul to use a substantial portion of its cash flow
       from operations to pay principal and interest on its indebtedness,
       which reduces the funds the Company will have available to finance
       operations and future business opportunities;
 
    . place Federal-Mogul at a competitive disadvantage to those of its
       competitors that may be less leveraged; and
 
    . increase Federal-Mogul's vulnerability to adverse economic and industry
       conditions.
 
  In addition, since certain of Federal-Mogul's debt is at variable rates of
interest, Federal-Mogul will be vulnerable to increases in interest rates.
Increases in interest rates could have a material adverse effect on Federal-
Mogul's operations, liquidity and financial condition. Federal-Mogul's ability
to make scheduled principal and interest payments on its indebtedness and its
ability to refinance its indebtedness depend on the Company's future
performance. This performance is, to a certain extent, subject to economic,
financial, competitive and other factors beyond Federal-Mogul's control.
 
                                     S-15
<PAGE>
 
  It is possible that in the future Federal-Mogul's business may not continue
to generate sufficient cash flow from operations to service its debt and make
necessary capital expenditures. If this occurs, Federal-Mogul may be required
to adopt one or more alternatives, such as reducing or delaying planned
expansion, selling assets, restructuring debt or obtaining additional equity
capital. There is no certainty that any of these strategies could be
implemented on satisfactory terms or without substantial additional expense
for Federal-Mogul. These and other factors could have a material adverse
effect on the results of operations, liquidity and financial condition of
Federal-Mogul and on the marketability, price and future value of the Common
Stock.
 
  The Credit Agreements (as hereinafter defined) limit Federal-Mogul's ability
to incur additional debt and to dispose of assets. The Credit Agreements also
require Federal-Mogul to make interest and principal payments and payments
from material disposals, from "excess cash flow" and from the proceeds of
certain issuances of capital stock or debt. The Company must also comply with
certain financial ratios and minimum net worth tests. See "Description of
Certain Indebtedness." There is no certainty that these requirements will be
met in the future. If Federal-Mogul does not comply with these requirements,
the resulting default under the Credit Agreements could lead to acceleration
of the related debt. Other indebtedness that contain cross-acceleration or
cross-default provisions could also be accelerated. In such a case, Federal-
Mogul might not be able to refinance or otherwise repay such indebtedness.
 
  Federal-Mogul may also incur substantial debt in the future, although its
ability to do so is restricted by the Credit Agreements. For more information
regarding the Company's debt and capitalization, see "Capitalization" and
"Description of Certain Indebtedness."
 
INTEGRATION OF BUSINESSES
 
  Federal-Mogul's business grew in size and complexity due to the acquisitions
of T&N, Fel-Pro and Cooper Automotive. Federal-Mogul must integrate
operations, management and personnel of four businesses that previously
operated independently and may encounter difficulties completing this
integration. Any material delays or unexpected costs the Company incurs in
connection with the integration process could have a material adverse effect
on Federal-Mogul and its results of operations, liquidity and financial
condition.
 
SYNERGY AND VALUATION OF CERTAIN ACQUIRED ASSETS AND LIABILITIES
 
  Federal-Mogul analyzed possible economic synergies it hoped to realize as a
result of the acquisitions of T&N, Fel-Pro and Cooper Automotive. It is
possible that Federal-Mogul will not achieve the desired levels of synergies.
If the Company fails to achieve its desired levels of synergies, it could have
a material adverse effect on the business, results of operations, liquidity
and financial condition of Federal-Mogul.
 
  Federal-Mogul has announced that it intends to incur restructuring charges
and related costs of $195 million in connection with synergies targeted for
the T&N and Fel-Pro acquisitions. Of this amount, $54 million will be
recognized as expense as incurred and $141 million was recorded as a direct
cost of the acquisitions. This is moderately less than the annual level of
synergy benefits anticipated from those acquisitions in the year 2000. See
"Recent Acquisitions." In connection with the Cooper Acquisition, Federal-
Mogul expects to incur restructuring charges and related costs of $126
million. Of this amount, $38 million will be recognized as expense as incurred
and $88 million was recorded as a direct cost of the acquisition. See Annex I
to this Prospectus Supplement. It is possible that such costs will be
substantially greater than these amounts or that achieving such synergies will
require additional costs or charges to earnings in future periods. In
connection with the acquisitions of T&N, Fel-Pro and Cooper Automotive, the
Company is performing valuations of certain acquired assets and liabilities.
The unaudited pro forma financial information is based upon preliminary
available information and upon certain assumptions made by management of
Federal-Mogul. As a result, the financial information may be materially
revised as new information becomes available. Any such cost or charges could
have a material adverse effect on the business, results of operations,
liquidity and financial condition of Federal-Mogul.
 
T&N'S ASBESTOS LIABILITY
 
  T&N and certain of its subsidiaries are among many defendants named in a
large number of court actions brought in the United States, and a smaller
number of claims brought in the United Kingdom, relating to alleged asbestos-
related diseases resulting from exposure to asbestos or products containing
asbestos. T&N is also one of many defendants named in a small number of U.S.
property damage claims. Prior to and including 1996, T&N
 
                                     S-16
<PAGE>
 
incurred significant charges to income in connection with settling claims,
establishing reserves for asbestos liabilities and obtaining insurance
coverage for certain asbestos liabilities. Prior to its acquisition by
Federal-Mogul, T&N secured, by payment of a premium of (Pounds)92 million, a
(Pounds)500 million layer of insurance which will be triggered should the
aggregate number of claims notified after June 30, 1996, where the exposure
occurred prior to that date ("IBNR claims"), exceed (Pounds)690 million. In
connection with the T&N acquisition, Federal-Mogul recorded reserves for IBNR
claims up to the self-retention amount of T&N's IBNR insurance policies. In
addition, the Company has provided reserves for claims notified before June
30, 1996. As of September 30, 1998, the Company has provided $1.292 billion as
its estimate for future costs related to resolving asbestos claims. For a more
detailed description of T&N's asbestos liabilities and the financial impact of
these liabilities on the Company, see "Business--Legal Proceedings,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Federal-Mogul--Asbestos Liability and Legal Proceedings" "--T&N--
Asbestos" and Notes 19 and 28 to the T&N Financial Statements (found in the
Company's Form 8-K filed on April 7, 1998). Although T&N has carefully
projected its future asbestos liability, the assumptions underlying such
projections continuously change and it is therefore not possible to project
with certainty the number of such claims that may be made nor the expenditure
which may arise therefrom. T&N may be subject to material additional
liabilities and significant additional litigation relating to asbestos that
would result in additional charges not covered by reserves or insurance. Any
such liabilities or litigation could have a material adverse effect on
Federal-Mogul's results of operations, business, liquidity and financial
condition.
 
ACQUISITION STRATEGY
 
  One of Federal-Mogul's principal business strategies is to acquire
businesses in order to expand its manufacturing and distribution capabilities.
Federal-Mogul intends to acquire companies that it believes complement its
existing business and will achieve satisfactory rates of return. Federal-Mogul
is usually engaged in various stages of evaluating potential acquisition
candidates, and the Company expects to complete as quickly as possible any
acquisition that it believes meets its criteria. Federal-Mogul may not succeed
in completing each potential acquisition and may not in the future succeed in
locating and acquiring appropriate companies on attractive terms, integrating
acquired companies or realizing desired benefits of such acquisitions.
 
  Federal-Mogul believes that it will require significant capital expenditures
to successfully implement its acquisition strategy, which it might not be able
to fund from its cash from operations. Therefore, Federal-Mogul may borrow
money or otherwise obtain financing for future acquisitions. Holders of the
Common Stock may be affected by Federal-Mogul's incurrence of additional debt.
See "--Effect of Substantial Leverage." If Federal-Mogul is unable to obtain
suitable financing, it may be unable to complete future acquisitions.
 
CYCLICAL NATURE OF AUTOMOTIVE INDUSTRY
 
  Federal-Mogul's principal operations are directly related to automobile
sales and production in the United States and abroad. Automobile sales and
production are cyclical and can be affected by the strength of a country's
general economy. In addition, automobile production and sales can be affected
by labor relations, regulatory requirements, trade agreements and other
factors. A decline in automotive sales and production would likely affect not
only sales to original equipment customers (purchasers of new automobiles) but
also sales to aftermarket customers (purchasers of replacement parts) and
could result in a decline in Federal-Mogul's results of operations or a
deterioration in Federal-Mogul's financial condition. If demand changes and
Federal-Mogul fails to respond appropriately, its results of operations could
be adversely affected. In addition, technical improvements in automotive
component designs may adversely affect aftermarket demand.
 
INTERNATIONAL OPERATIONS
 
  Federal-Mogul has manufacturing and distribution facilities in many
countries, principally in North America, Europe and Latin America. The
acquisition of T&N significantly increased the portion of Federal-Mogul's
business located outside the United States, though the Cooper Acquisition will
partially offset this effect. International operations are subject to certain
risks including (i) exposure to local economic conditions, (ii) exposure to
local political conditions (including the risk of seizure of assets by foreign
governments), (iii) currency exchange rate fluctuations and currency controls
and (iv) export and import restrictions. The likelihood of such occurrences
and their potential effect on Federal-Mogul are unpredictable and vary from
country to country.
 
                                     S-17
<PAGE>
 
FOREIGN CURRENCY RISK
 
  Certain Federal-Mogul operating entities report their financial condition
and results of operations in various foreign currencies (including pounds
sterling, German marks and, to a lesser extent South African rand and French
francs). Federal-Mogul translates the reported amounts into U.S. dollars at
the applicable exchange rates in preparing its consolidated financial
statements. As a result, the fluctuating value of the dollar against these
foreign currencies will affect reported sales and operating margin of T&N and
other subsidiaries, as consolidated into Federal-Mogul. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Federal-Mogul--Year Ended December 31, 1997 Compared with Year Ended December
31, 1996 and Year Ended December 31, 1996 Compared with Year Ended December
31, 1995--Foreign Currency and Commodity Contracts."
 
  In addition, Federal-Mogul is exposed to a risk of loss from changes in
foreign exchange rates whenever Federal-Mogul or one of its foreign
subsidiaries enters into a purchase or sales transaction using a currency that
is not its normal currency. While the Company reduces such risks by matching
revenues and costs with the same currency, changes in currency exchange rates
could have a material adverse effect on Federal-Mogul's financial condition or
results of operations.
 
COMPETITION
 
  The global vehicular parts business is highly competitive. Federal-Mogul
competes with many of its customers that produce their own components as well
as with independent manufacturers and distributors of components in the United
States and abroad. Certain of the Company's competitors have significantly
greater financial and other resources than the Company. If the Company is
unable to respond successfully to changing competitive conditions demand for
its products may decline.

                                USE OF PROCEEDS
 
  The net proceeds to Federal-Mogul from the sale of the 14.0 million shares
of Common Stock offered in the Offerings are estimated to be $773.6 million
($889.7 million if the Underwriters' over-allotment options are exercised in
full). This assumes a public offering price of $56 15/16 per share, after
deducting the estimated underwriting discount and offering expenses, estimated
at $23.6 million ($27.0 million if the Underwriters' over-allotment options
are exercised in full).
 
  Federal-Mogul intends to use the net proceeds of the Offerings to prepay a
portion of the New Interim Loans (as defined below), the outstanding principal
balance of which is $1.55 billion. The New Interim Loans currently bear
interest at a floating rate based upon, at Federal-Mogul's option, either (i)
the higher of the prime rate of The Chase Manhattan Bank ("Chase") and 0.5% in
excess of the overnight federal funds rate, plus (in each case) a margin of
1.25% or (ii) the average of the offering rates of certain banks in the London
interbank eurodollar market for U.S. dollar deposits plus a margin of 2.25%.
The New Interim Loans are scheduled to mature on April 9, 2000. Amounts
borrowed under the New Interim Loans were used as part of the financing of the
acquisition of Cooper Automotive. See "Recent Acquisitions--Financing of the
Acquisitions" and "Description of Certain Indebtedness."

                              RECENT ACQUISITIONS
 
  As part of its strategy to expand its core competencies in manufacturing and
distribution, Federal-Mogul acquired T&N, Fel-Pro and Cooper Automotive, three
other significant automotive parts manufacturers and distributors, in March,
February and October 1998, respectively.
 
THE COOPER ACQUISITION
 
  On October 9, 1998, the Company acquired Cooper Automotive for a total
purchase price of $1.9 billion. The Company incurred approximately $25 million
of fees and expenses (consisting of $19.5 million of debt financing costs and
$5.5 million of direct transaction costs) in connection with the Cooper
Acquisition.
 
  Cooper Automotive consists of the Cooper Automotive Division (the Champion
spark plug group of companies) and the Moog Automotive Division of Cooper
Industries, Inc. Cooper Automotive is a premier provider of leading brand name
automotive products to the aftermarket and original equipment ("OE") market.
Cooper Automotive manufactures and distributes brake and friction products,
chassis products, ignition products, lighting and wiper products under well-
known brand names including Champion, Moog, Abex, Wagner and Zanxx. Among
Cooper Automotive's largest customers are AutoValue, Carquest,
DaimlerChrysler, Ford, Fiat, General Motors and NAPA (in alphabetical order).
Cooper Automotive had sales in 1997 of $1.9 billion.
 
  A DESCRIPTION OF THE COOPER ACQUISITION, A DESCRIPTION OF COOPER
AUTOMOTIVE'S BUSINESS AND FINANCIAL INFORMATION REGARDING COOPER AUTOMOTIVE IS
INCLUDED IN THIS PROSPECTUS SUPPLEMENT AS ANNEX I.
 
THE T&N ACQUISITION
 
  On March 6, 1998, Federal-Mogul acquired T&N for total consideration of
approximately (Pounds)1.46 billion ($2.41 billion, converted at a blended
exchange rate of 1 pound sterling to 1.6510 U.S. dollars). T&N, headquartered
in Manchester, England, manufactures and supplies high technology engineered
automotive components and industrial materials. In 1997, T&N had sales of
approximately (Pounds)1.80 billion ($2.96 billion) with about 80% of such
sales relating to the world automotive industry. In connection with securing
regulatory approvals for the acquisition of T&N, Federal-Mogul agreed with the
FTC to divest the T&N Bearings Business. See "Business--Reorganization" and
"Unaudited Pro Forma Financial Data: T&N, Fel-Pro and Cooper Automotive." The
T&N Bearings Business accounted for approximately $393.1 million of T&N's 1997
revenues and employed approximately 4,000 people.
 
  On October 27, 1998, Federal-Mogul entered into an agreement to sell the T&N
Bearings Business and certain other engine hard part assets to Dana
Corporation for a purchase price of $430 million. Completion of the sale is
subject to regulatory approval and is expected to occur by the end of 1998.
 
THE FEL-PRO ACQUISITION
 
  On February 24, 1998, Federal-Mogul acquired Fel-Pro, a group of privately-
owned automotive parts manufacturers headquartered in Skokie, Illinois. The
total consideration paid for Fel-Pro was approximately $717 million, which
included 1,030,325.6 shares of Federal-Mogul Series E Mandatory Exchangeable
Preferred Stock ("Series E Stock") with an imputed value of $225 million and
approximately $492 million in cash. Fel-Pro is a leading gaskets manufacturer
for the North American aftermarket and OE heavy duty market. In 1997, Fel-Pro
had sales of approximately $500 million. Federal-Mogul has since resold the
Fel-Pro Chemical Business (representing approximately $32.8 million of Fel-
Pro's 1997 net sales and $2.6 million of Fel-Pro's 1997 net income).
 
STRATEGIC RATIONALE FOR THE ACQUISITIONS
 
The principal benefits to Federal-Mogul from the acquisitions of T&N, Fel-Pro
and Cooper Automotive are as follows:
 
  . Establishing Federal-Mogul as a highly competitive first tier worldwide
    automotive supplier.
 
  . Expanding Federal-Mogul's manufactured product portfolio to offer
    complete systems and modules.
 
                                     S-20
<PAGE>
 
  . Enhancing Federal-Mogul's position as a global supplier of engine and
    transmission parts.
 
  . Reinforcing Federal-Mogul's ability to provide high quality service to
    both its original equipment and aftermarket customers.
 
  . Extending Federal-Mogul's international presence and accelerating its
    worldwide aftermarket growth.
 
  . Broadening Federal-Mogul's brake/friction and ignition system
    capabilities.
 
SYNERGIES AND COST BENEFITS
 
  Federal-Mogul expects significant pre-tax synergies and cost benefits to be
achieved as a result of the acquisitions of T&N, Fel-Pro and Cooper
Automotive. Federal-Mogul has announced that it intends, in connection with
its targeted synergies, to incur various restructuring charges and related
costs. The Company currently anticipates realizing approximate pre-tax
synergies and cost benefits and funding approximate restructuring charges and
related costs in connection with these acquisitions as follows.

    Acquisition, $38 million is to be recognized as expense when incurred and
    $88 million was recognized as a direct cost of the acquisition.
 
FINANCING OF THE ACQUISITIONS
 
  The acquisition of T&N was funded primarily through a $2.75 billion floating
rate 1997 Credit Agreement (as hereinafter defined) (consisting of a $2.35
billion term loan facility and a $400 million revolving loan facility) and a
$500 million floating rate Senior Subordinated Credit Agreement (as
hereinafter defined). The senior term loan facility was reduced to $2.275
billion effective as of March 11, 1998. The entire amount of the senior term
loan facility, as well as the entire amount of the senior subordinated credit
facility, were drawn down. These credit facilities also refinanced Federal-
Mogul's $350 million indebtedness under a revolving credit facility (which had
been used to finance the acquisition of Fel-Pro) and $150 million of other
indebtedness incurred in the acquisition of Fel-Pro. Federal-Mogul used the
proceeds of the sale of shares of its Common Stock in an underwritten public
offering in June 1998 as well as the proceeds from the issuance of notes in
the principal amount of $1 billion in June 1998, to prepay the entire
outstanding $500 million principal amount of the loans under the Senior
Subordinated Credit Agreement and a portion of the outstanding principal
amount under the 1997 Credit Agreement ($1,076.8 million). See "Description of
Certain Indebtedness."
 
                                     S-21
<PAGE>
 
  Additional funds for the acquisition of T&N were obtained through the sale
in December 1997 of 11,500,000 7% Trust Convertible Preferred Securities
(generating gross proceeds of $575 million) by Federal-Mogul Financing Trust,
a subsidiary of Federal-Mogul which invested the net proceeds of that offering
in 7% Convertible Junior Subordinated Debentures of Federal-Mogul. See
"Description of Capital Stock--Trust Preferred Securities." Federal-Mogul also
issued 1,030,325.6 shares of Series E Stock, with an imputed value of $225
million, as partial consideration for the acquisition of Fel-Pro.
 
  The acquisition of Cooper Automotive was funded primarily through a $1.95
billion floating rate Term Loan Agreement (as hereinafter defined) and a $200
million 364-day floating rate Revolving Credit Agreement (as hereinafter
defined). The proceeds of the Offerings will be used to repay a portion of the
loans incurred under the Term Loan Agreement in connection with the Cooper
Acquisition. See "Use of Proceeds" and "Description of Certain Indebtedness."

  On December 14, 1998, the reported last sale price of the Common Stock on
the NYSE was $56 15/16 per share. On that date, there were approximately 8,600

  Dividends on the Common Stock of Federal-Mogul are payable at the discretion
of Federal-Mogul's Board of Directors out of funds legally available therefor.
The Board of Directors has declared a cash dividend payable in the fourth
quarter of 1998 in the amount of $.0025 per share of Common Stock. The record
date for this dividend was November 27, 1998. Common Stock sold in the
Offerings will not entitle holders to receive this dividend. Management
presently intends to retain future earnings for working capital, in accordance
with Federal-Mogul's growth strategy, and therefore anticipates paying
dividends at a comparable level in the foreseeable future. In addition, the
Credit Agreements contain certain limits upon dividends. See "Description of

    UNAUDITED PRO FORMA FINANCIAL DATA: T&N, FEL-PRO AND COOPER AUTOMOTIVE*
 
  Federal-Mogul completed its cash offer to acquire T&N on March 6, 1998. The
acquisition has been accounted for using the purchase method of accounting.
The total consideration paid of approximately (Pounds)1.46 billion ($2.41
billion, converted at a blended exchange rate of 1 pound sterling to 1.6510
U.S. dollars) was funded primarily through the $2.75 billion floating rate
1997 Credit Agreement (consisting of a $2.35 billion (reduced to $2.275
billion effective as of March 11, 1998) term loan facility and a $400 million
revolving loan facility) and a $500 million floating rate Senior Subordinated
Credit Agreement, each from a syndicate led by Chase. These credit facilities
also refinanced the borrowings used to finance the cash portion of the
purchase price for Fel-Pro. Additional funds for the acquisition of T&N were
obtained through the December 1997 sale of 7% Trust Convertible Preferred
Securities (generating gross proceeds of $575 million) by Federal-Mogul
Financing Trust, a subsidiary of the Company.
 
  Federal-Mogul completed the acquisition of Fel-Pro, for approximately $717
million, on February 24, 1998. The acquisition has been accounted for using
the purchase method of accounting. The purchase price consists of 1,030,325.6
shares of newly issued Series E Stock (exchangeable into 5,151,628 shares of
Common Stock) with an imputed value of $225 million and $492 million in cash.
The cash was provided through an existing revolving credit facility provided
by a syndicate led by Chase and three short-term loans, each in the amount of
$50 million, from Chase, ABN Amro Bank NV and First Chicago NBD Bank,
respectively. Portions of the debt incurred in financing the acquisitions of
T&N and Fel-Pro have since been re-financed. See "Description of Certain
Indebtedness."
 
  On June 10, 1998, Federal-Mogul completed a primary offering of 10,537,093
shares of Common Stock. Federal-Mogul used the net proceeds therefrom of
$592.3 million to repay outstanding debt incurred for financing the T&N
acquisition. In addition, 422,581 shares of the Series E Stock were converted
to 2,112,907 shares of common stock and were sold in a secondary offering by
the holders thereof (collectively, the "June Equity Offering").
 
  On October 9, 1998, Federal-Mogul acquired Cooper Automotive for a total
purchase price of $1.9 billion, excluding fees and expenses. The acquisition
has been accounted for using the purchase method of accounting. The purchase
price was funded from borrowings under the Company's Credit Agreements.
 
  The estimated cost of the acquisition of Cooper Automotive is computed as
follows:

  In connection with securing regulatory approvals for the acquisition of T&N,
Federal-Mogul executed an Agreement Containing Consent Order with the FTC on
February 27, 1998. Pursuant to this agreement, Federal-Mogul must divest the
T&N Bearings Business within six months after the FTC declares the consent
order final and must provide for independent management of the T&N Bearings
Business pending such divestiture. The agreement stipulates that the T&N
Bearings Business is to be maintained as a viable, independent competitor of
Federal-Mogul and that Federal-Mogul shall not attempt to direct the
activities of, or exercise control over, the T&N Bearings Business or have
contact with the T&N Bearings Business outside of normal business activities.
 
  The net assets of the T&N Bearings Business have been recorded at their fair
value based on estimates of selling values less costs to sell. Previously, the
Company had estimated proceeds to be between $500 and $650 million calculated
using multiples of earnings similar to recent automotive industry transactions
considering both the ability to conduct an orderly disposition and the
requirements of the FTC Consent Order. An amount within the low end of this
range was originally used to record the net assets with estimated after-tax
proceeds of approximately $400 million. At September 30, 1998, the proceeds
were estimated to be approximately $430 million, based on indications of
interest received from interested parties, with estimated after-tax proceeds
of approximately $372 million and excluding the net working capital impact.
Subsequently, the Company reached an agreement to sell the T&N Bearings
Business and proceeds are expected to approximate estimates used at September
30, 1998. See "Recent Developments." The Company's investment in the T&N
Bearings Business is included in the balance sheet caption "Acquired
businesses to be divested."
 
  In addition, Federal-Mogul held the Fel-Pro Chemical Business acquired in
the Fel-Pro transaction for sale. Federal-Mogul has separately identified the
estimated effect of the divestiture of the Fel-Pro Chemical Business in the
unaudited pro forma statements of operations. In July 1998, Federal-Mogul sold
the Fel-Pro Chemical Business for approximately $60 million. The net cash
flows from operations of the Fel-Pro Chemical Business, the interest expense
on debt incurred during the holding period and proceeds from the sale were
accounted for as adjustments to the purchase price of Fel-Pro.
 
  The unaudited pro forma statements of operations for the year ended December
31, 1997 and the nine months ended September 30, 1998, have been prepared to
illustrate the effect of the acquisitions of T&N, Fel-Pro and Cooper
Automotive, the dispositions of the T&N Bearings Business and the Fel-Pro
Chemical Business and the June Equity Offering and the Offerings, as if they
had occurred on the first day of each period. The unaudited pro forma
statements of operations include only the results of ongoing operations and
exclude such impacts as extraordinary items, nonrecurring items directly
relating to the acquisitions, expected synergies and expected cost benefits
associated with the integration of the acquisitions. The unaudited pro forma
balance sheet as of September 30, 1998, has been prepared to illustrate the
effect of the acquisition of Cooper Automotive and the Offerings as if they
had occurred on that date.
 
  The unaudited pro forma financial information gives effect to the
acquisition transactions using the purchase method of accounting. The pro
forma adjustments are described in the accompanying notes to the unaudited pro
forma financial information and are based upon preliminary available
information and upon certain assumptions made by management of Federal-Mogul.
Accordingly, the pro forma adjustments reflected in the unaudited pro forma
financial information are preliminary and subject to revision. Such revision
could be material.
 
  The unaudited pro forma financial information is presented for illustrative
purposes only and is not necessarily indicative of the financial position or
results of operations that would have occurred had the acquisitions of T&N,
Fel-Pro or Cooper Automotive, the dispositions of the T&N Bearings Business or
Fel-Pro Chemical Business, or the June Equity Offering or the Offerings been
consummated on the dates indicated, nor are they necessarily indicative of
Federal-Mogul's future results of operations or financial position. The
unaudited pro forma financial information should be read in conjunction with
the audited consolidated financial statements of Federal-Mogul, as well as the
audited financial statements of the acquired companies.

**The Company has made preliminary estimates of the fair values of fixed
assets, intangible assets and research, development in-process, and
postemployment benefits liabilities based upon the relative difference between
book values and fair values of previous acquisitions. The Company will have
valuations for such amounts completed by appraisers. The result of the
appraiser's valuations could differ materially from these estimates made by
the Company. The research and development in-process charge is not currently
determinable. However, the Company does not expect the charge, if any, to be
in excess of $10 million.

    a substitute for income from operations, net income or cash flow from
    operating activities, for the purpose of analyzing Federal-Mogul's
    operating performance, financial position and cash flows. EBITDA measures
    are calculated differently by other companies. As such, the EBITDA
    measures presented may not be comparable to other similarly titled
    measures of other companies. The Company has presented EBITDA because it
    is commonly used by investors to analyze and compare companies on the
    basis of operating performance and to determine a company's ability to
    service debt.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                          AND RESULTS OF OPERATIONS*
 
OVERVIEW
 
  Federal-Mogul is a leading global manufacturer and distributor of a broad
range of vehicular components for automobiles and light trucks, heavy duty
trucks, farm and construction vehicles and industrial products. The Company's
principal customers include many of the world's major OE manufacturers of such
vehicles and industrial products. The Company also manufactures and supplies
its products and related parts to the aftermarket.
 
  The Company, which had traditionally focused on the manufacture and
distribution of engine bearings and sealing systems, in 1990 began to add
retail auto stores in various domestic and international locations. These
geographically-dispersed stores proved burdensome to manage and resulted in
substantial operating losses. In the fourth quarter of 1996, Federal-Mogul
underwent a change of management, following which the Company initiated a
significant restructuring program designed to refocus the Company on its core
competency of manufacturing. As part of such restructuring, Federal-Mogul took
the following actions: (i) closed international aftermarket distribution
centers in Malaysia and Singapore; (ii) divested 94 international retail
aftermarket operations and sold or restructured 25 wholesale aftermarket
operations; (iii) closed its Leiters Ford, Indiana manufacturing facility and
consolidated its lighting products operations in Juarez, Mexico; (iv)
consolidated certain of its North American warehouse facilities; (v)
consolidated its customer support functions previously housed in Phoenix,
Arizona into the Company's Southfield headquarters; (vi) consolidated its
European aftermarket management functions in Geneva, Switzerland into the
Wiesbaden, Germany manufacturing headquarters; and (vii) streamlined certain
of its administrative and operational staff functions worldwide. By June 30,
1998, the Company had divested substantially all of its retail assets.
 
  In connection with the restructuring, Federal-Mogul also began to pursue a
growth strategy of acquiring complementary manufacturing companies that
enhance Federal-Mogul's product base, expand its global manufacturing
operations and provide opportunities to capitalize on Federal-Mogul's
aftermarket distribution network and technological resources.
 
  On March 6, 1998, Federal-Mogul completed its cash offer to acquire all
outstanding common stock of T&N for 260 pence per share. On February 24, 1998,
Federal-Mogul acquired all the equity interests of Fel-Pro. See "Recent
Acquisitions."
 
  The Company also acquired Bimet S.A. ("Bimet") during the first quarter of
1998 and increased its ownership in Federal-Mogul/Bruss Sealing Systems
("Summerton") and KFM Bearing Co., Ltd. ("KFM"), as well as divesting its
minority interest in G. Bruss GmbH & Co. KG ("Bruss") and selling the Fel-Pro
Chemical Business, which was acquired as part of Fel-Pro.
 
  The consolidated statement of operations for the nine months ended September
30, 1998 includes the operating results of T&N and Fel-Pro from their
respective acquisition dates. Operating results for the T&N Bearings Business
and the Fel-Pro Chemical Business (which includes amortization expense for
goodwill allocated to the businesses and interest expense relating to the
holding costs of the businesses) have been excluded from the condensed
consolidated statement of operations for the nine months ended September 30,
1998.

*On October 9, 1998 the Company acquired Cooper Automotive for $1.9 billion,
  excluding fees and expenses. INFORMATION REGARDING THE COOPER ACQUISITION
  AND ITS EFFECT UPON THE COMPANY IS FOUND IN ANNEX I TO THIS PROSPECTUS
  SUPPLEMENT AND IS NOT REFLECTED IN THIS SECTION.

                                 FEDERAL-MOGUL
 
  THE FOLLOWING IS BASED ON TEXT INCLUDED IN FEDERAL-MOGUL'S QUARTERLY REPORT
ON FORM 10-Q FILED IN RESPECT OF THE NINE-MONTH PERIOD ENDED SEPTEMBER 30,
1998 AND SPEAKS AS OF THAT DATE.
 
 NINE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED TO NINE MONTHS ENDED SEPTEMBER
                                   30, 1997
 
RESULTS OF OPERATIONS
 
 Net Sales
 
  Sales for the nine months ended September 30, 1998 were $2,993.2 million
compared to $1,391.6 million for the same 1997 period. The 115.1% increase in
net sales is primarily attributable to the acquisitions of T&N and Fel-Pro the
results of which were included from their respective dates of acquisition.
Excluding the impact of the T&N and Fel-Pro acquisitions and the impact of
previously divested retail aftermarket businesses, net sales decreased 4.2%.
 
  Powertrain Systems sales were $1,269.4 million for the nine months ended
September 30, 1998 compared to $608.2 million for the same 1997 period.
Approximately $694 million of the 108.7% increase related to sales of T&N.
Excluding the acquisition of T&N and Powertrain products previously sold
through the divested retail aftermarket businesses, sales decreased 2.2%. The
decrease in sales is attributable to effects from the General Motors strike as
well as softness in the North American aftermarket business.
 
  Sealing Systems sales were $663.4 million for the nine months ended
September 30, 1998 compared to $238.5 million in the same 1997 period.
Approximately $135 million of the 178.2% increase related to sales of T&N and
approximately $278 million related to sales of Fel-Pro. Excluding the
acquisitions of T&N and Fel-Pro and sealing products previously sold through
the divested retail aftermarket businesses, sales increased 5.4% due to strong
heavy duty and industrial sales as well as strong third quarter volume in both
North and South American aftermarket businesses.
 
  General Products sales were $1,060.4 million for the nine months ended
September 30, 1998 compared to $544.9 million in 1997. Approximately $617
million of the 94.6% increase related to sales of T&N. Excluding the
acquisitions of T&N and general products previously sold through the divested
retail aftermarket businesses, sales decreased 11.2% primarily due to
continuing softness in the North American aftermarket business.
 
 Cost of Products Sold
 
  Cost of products sold as a percent of net sales decreased to 74.2% for the
nine months ended September 30, 1998 from 76.3% for the same 1997 period.
Excluding the effect of a $10.9 million charge in the first quarter of 1998
associated with the purchase accounting write-up of acquired inventory to fair
value and the subsequent sale of this inventory at the higher cost, as well as
a $6.4 million write-down of inventory, primarily related to the liquidation
of the Puerto Rican retail assets, cost of products sold as a percent of sales
decreased to 73.6%. Management attributes this decrease to productivity
improvements, cost controls, streamlined operations, the divestiture of
underperforming assets and the acquisitions previously discussed.
 
 Selling, General and Administrative Expenses
 
  Selling, general and administrative ("SG&A") expenses as percent of net
sales decreased to 14.4% for the nine months ended September 30, 1998 compared
to 15.7% for the same 1997 period. The decrease is primarily attributable to
the benefits of prior restructuring actions, the divestiture of retail
aftermarket businesses and the realization of combined efficiencies from the
acquisitions previously discussed slightly offset by an approximately $4
million increase related to Year 2000 costs.
 
 
                                     S-45

 Amortization Expense
 
  Amortization expense for the nine months ended September 30, 1998 was $60.4
million compared to $7.9 million for the nine months ended September 30, 1997.
The increase in amortization expense was attributable to the expense related
to the increase in goodwill and other intangible assets associated with the
T&N and Fel-Pro acquisitions.
 
 Purchased In-Process Research and Development Charge
 
  The Company recognized an $18.6 million charge in the first quarter of 1998
associated with the estimated fair value of in-process research and
development costs allocated in purchase accounting to a portion of the total
consideration paid.
 
 Restructuring Charges
 
  During the first quarter of 1998, the Company recognized a $10.5 million
restructuring charge related to operations in place prior to the acquisitions
of T&N and Fel-Pro. The restructuring charge included $10.2 million and $0.3
million for severance and exit costs, respectively. Employee severance costs
result from planned terminations in various business operations of the
Company. The severance costs were based on the estimated levels that will be
paid to the affected employees pursuant to the Company's workforce reduction
policies and certain foreign governmental regulations. The Company anticipates
that the actions related to the first quarter 1998 restructuring plan will be
completed primarily within one year.
 
  During the third quarter of 1998, the Company recognized a $6.6 million
restructuring credit for the reversal of a restructuring charge recorded in
the fourth quarter of 1997. The restructuring credit primarily related to the
exit of retail operations in Puerto Rico.
 
 Rationalization of Acquired Businesses
 
  In connection with the previously discussed acquisitions, the Company
recognized approximately $151 million in reserves related to the
rationalization and integration of acquired businesses. The rationalization
reserves provide for approximately $125 million and $26 million in severance
and exit costs, respectively.
 
  The components of the integration plan include: closure of certain
manufacturing facilities worldwide; relocation of highly manual manufacturing
product lines to lower cost regions or more suitable locations; consolidation
of overlapping manufacturing, technical and sales facilities and joint
ventures; closure of two aftermarket central warehouses and five in-country
warehouses; consolidation of aftermarket marketing and customer support
functions; and streamlining of administrative, sales, marketing and product
engineering staffs worldwide. An anticipated result of the integration plan
and the restructuring will be a reduction of approximately 4,200 full-time
employees.
 
 Adjustment of Assets Held for Sale to Fair Value
 
  In addition to the T&N Bearings Business and the Fel-Pro Chemical Business
held for sale, during 1998, the Company decided to sell its subsidiary,
Bertolotti Pietro e Figli, S.r.l. ("Bertolotti"), conducting aftermarket
operations in Italy. The carrying value of Bertolotti's assets have been
reduced to its fair value based on estimates of selling values less costs to
sell, calculated using multiples of earnings similar to recent automotive
industry transactions in Italy. The Company recognized a $20.0 million first
quarter charge primarily associated with the write-down of Bertolotti's assets
to the estimated fair value. The Company expects to complete the sale of
Bertolotti within one year.
 
  In the second quarter, the Company recognized a $1.0 million benefit
associated with the adjustment of the assets of Chile to its estimated fair
value.
 
                                     S-46
<PAGE>
 
  As part of its 1996 restructuring plan, the Company continued to close or
sell certain retail aftermarket operations during 1998. As of September 30,
1998, the Company has sold or closed substantially all its retail aftermarket
operations. Net cash proceeds received for those retail aftermarket locations
sold in the nine months ended September 30, 1998 approximated $7 million. No
gain or loss was recognized on the dispositions of those retail aftermarket
locations, as the related assets had been previously adjusted to fair value.
 
 Integration Costs
 
  In the nine months ended September 30, 1998, the Company incurred $13.7
million in expenses directly related to the integration of the T&N and Fel-Pro
acquisitions previously discussed. In addition, the Company expects to incur
additional expenses of approximately $24 million necessary to complete the
integration of the acquired companies during the fourth quarter of 1998 and
throughout 1999.
 
 Anticipated Synergy
 
  The Company anticipates its annual synergies in the year 2000 to be
moderately in excess of the previously discussed $10.5 million restructuring,
$151 million rationalization and $38 million of expected integration costs.
 
 Net Interest Expense
 
  Interest expense for the nine months ended September 30, 1998 was $107.4
million compared to $25.3 million for the same 1997 period. The increase in
interest expense is attributable to the interest expense related to the
financing of the T&N and Fel-Pro acquisitions slightly offset by reduced
preacquisition debt levels as compared to the nine months ended September 30,
1997.
 
 Net Gain on British Pound Currency Option and Forward Contract
 
  In the fourth quarter of 1997, in anticipation of the then pending T&N
acquisition, the Company purchased a British pound currency option for $28.1
million with a notional amount of $2.5 billion. In January 1998, the Company
settled the option and recognized a loss of $17.3 million.
 
  Also in January 1998, in anticipation of the then pending T&N acquisition,
the Company entered into a forward contract to purchase 1.5 billion pounds
sterling for a notional amount of approximately $2.45 billion. As a result of
favorable exchange fluctuations in the British pound/U.S. dollar exchange rate
experienced during the contract period, the Company recognized a $30.6 million
gain.
 
  The Company entered into the above transactions to effectively serve as
economic hedges for the purchase of T&N. Such transactions, however, do not
qualify for "hedge accounting" under U.S. GAAP, and therefore the loss on the
British pound currency option and the gain on the British pound forward
contract are reflected in the statement of operations caption "Net gain on
British pound currency option and forward contract."
 
 Income Tax Expense
 
  During the nine months ended September 30, 1998, the Company recognized
charges for adjustment of assets held for sale to fair value and purchased in-
process research and development and recognized a net gain on the British
pound currency option and forward contract. These transactions resulted in a
pre-tax net charge of $24.3 million. The net income tax benefit related to
these transactions totaled $2.1 million. In addition, due to the acquisitions
of T&N and Fel-Pro, the Company recognized approximately $28 million in non-
deductible goodwill amortization expense.

LIQUIDITY AND CAPITAL RESOURCES
 
 Cash Flow Provided from Operating Activities
 
  Cash flow provided from operating activities was $228.1 million for the nine
months ended September 30, 1998. Cash flow was generated primarily from a
decrease in inventories of $47.0 million, an increase in other accrued
liabilities of $51.4 million and net earnings adjusted for the loss on early
retirement of debt and the non-cash charges of depreciation and amortization,
purchased in-process research and development, restructuring and adjustment of
assets held for sale to fair value. Partially offsetting these items was an
increase in accounts receivable of $25.7 million, payments against the
asbestos liability of $58.8 million and payments against restructuring,
reengineering and rationalization reserves of $35.7 million.
 
 Cash Flow Used by Investing Activities
 
  Cash flow used by investing activities was $2,766.8 million and was
primarily related to the acquisitions of T&N, Fel-Pro, Bimet and the increase
in ownership of Summerton and KFM partially reduced by the sale of the
Company's interest in G. Bruss GmbH & Co. KG and the sale of certain retail
aftermarket locations. Partially offsetting the acquisitions, the Company
received proceeds from the sale of options which were acquired with the
acquisition of T&N. In addition, capital expenditures of $129.1 million were
made for property, plant and equipment to implement process improvements,
information technology and new product introductions. Capital expenditures are
anticipated not to exceed $200 million in 1998, primarily for enhanced
manufacturing capabilities and process improvements.
 
 Cash Flow Provided from Financing Activities
 
  Cash flow provided from financing activities was $2,099.6 million for the
nine months ended September 30, 1998 primarily from the increase in debt
related to the acquisitions of T&N and Fel-Pro and the issuance of common
stock detailed below, partially offset by the related debt issuance fees of
$55.3 million and fees paid for the early retirement of debt of $27.4 million.
 
  On April 17, 1998, in connection with the Company's efforts to put into
place a permanent capital structure, the Company filed a shelf Registration
Statement on Form S-3 with the Securities and Exchange Commission for the
offering from time to time of up to an aggregate $2.5 billion of debt or
equity securities (including shares of common stock registered for the account
of certain securityholders).
 
  On June 6, 1998, the Company issued 12,650,000 shares of common stock under
such registration statement, including 2.1 million shares which were converted
from Series E Stock. The net proceeds from the sale of the common stock of
$592 million was used to prepay the entire outstanding principal amount under
the Senior Subordinated Credit Agreement and partially repay the Senior Credit
Agreement.
 
  In addition, under the above shelf registration statement, the Company
issued $1.0 billion of bonds on June 25, 1998. The bonds have maturities
ranging from 6 to 12 years, a weighted average yield of 7.76% and a weighted
average coupon of 7.73%. The net proceeds were used to reduce floating rate
bank debt.
 
  As of September 30, 1998, the Company had $1.1 billion outstanding related
to the Senior Credit Agreement with maturities ranging from March of 1999
through the year 2005 and a weighted-average interest rate of 7.9%. Over 60%
of the maturities occur after the year 2003.
 
  In addition, the Company funded a portion of the T&N acquisition through the
December 1997 sale of 11.5 million shares of 7% Company-obligated mandatorily
redeemable preferred securities of subsidiary trust holding solely convertible
subordinated debentures of the Company (generating gross proceeds of $575
million) by Federal-Mogul Financing Trust, a subsidiary of the Company.
 
  The early retirement of the Senior Subordinated Credit Agreement and the
partial repayment of the Senior Credit Agreement, as well as the early
retirement in April 1998 of $251 million in private placement debt
 
                                     S-48
<PAGE>
 
assumed in connection with the acquisition of T&N, resulted in a $47.1 million
pretax ($31.3 million after tax) extraordinary loss in the second quarter of
1998.
 
  In connection with the Fel-Pro acquisition, the Company issued 1,030,325.6
million shares Series E Stock with an imputed value of $225 million. The
shares of Series E Stock are exchangeable into shares of the Company's common
stock at a rate of five shares of common stock per share of Series E Stock.
Subsequently, in June 1998, in conjunction with the common stock offering, the
Company converted 422,581 shares of Series E Stock into 2.1 million shares of
common stock. The remaining 607,745 million shares of Series E Stock are
required to be exchanged into shares of the Company's common stock no later
than February 24, 1999, subject to certain conditions and such shares are paid
quarterly dividends at a rate of $0.12 per common stock equivalent.
 
  The Company has pledged the capital stock of its U.S. subsidiaries, 65% of
capital stock of certain foreign subsidiaries and certain intercompany loans
to secure the senior debt of the Company. In addition, certain U.S.
subsidiaries of the Company have guaranteed the senior debt.
 
  The Company believes that cash flow from operations, together with
borrowings available under the Company's revolving credit facility, will
continue to be sufficient to meet its ongoing working capital requirements.
 
 Foreign Currency and Commodity Contracts
 
  The financial condition and results of operations of certain of the
Company's operating entities are reported in various foreign currencies
(principally pounds sterling, German marks, and to a lesser extent South
African rand and French francs, among others) and then translated into U.S.
dollars at the applicable exchange rate for inclusion in the Company's
financial statements. As a result, the appreciation of the dollar against
these foreign currencies will have a negative impact on the reported sales and
operating margin of international T&N operations and other international
subsidiaries as consolidated into the Company. Conversely, the depreciation of
the dollar against these foreign currencies will have a positive impact.
 
  In addition, the Company incurs currency transaction risk whenever it or one
of its international subsidiaries enters into either a purchase or sales
transaction using a different currency than the relevant entity's functional
currency. Currency transaction risk is reduced by matching revenues and costs
with the same currency. Given the volatility of currency exchange rates, there
can be no assurance that the Company will be able to effectively manage its
currency transaction risks or that any volatility in currency exchange rates
will not have a material adverse effect on the Company's financial condition
or results of operations.
 
OTHER MATTERS
 
 New Dividend Policy
 
  Dividends on the capital stock of the Company are payable at the discretion
of the Company's Board of Directors. Historically, quarterly dividends had
been $.12 per share. In May 1998, the Board of Directors reduced the quarterly
dividend and subsequently declared a cash dividend payable in the second and
third quarters of 1998 in the amount of $.0025 per share of common stock. The
Company, consistent with its growth strategy, presently intends to retain
future earnings in the business and therefore anticipates paying dividends at
a comparable level in the foreseeable future.
 
 Year 2000 Costs
 
  The Year 2000 issue is the result of computer programs being written using
two digits rather than four to define the applicable year. The Company has
established a team that has completed an awareness program and assessment
project to address the Year 2000 issue including information technology ("IT")
and non-IT systems. In addition, the Board of Directors has received status
reports related to the Company's progress in addressing the Year 2000 issue.
The Company has determined that it will be required to modify or replace
portions of its
 
                                     S-49
<PAGE>
 
software so that its computer systems will properly utilize dates beyond
December 31, 1999. The Company has initiated remediation and testing, and is
implementing the action plan to address the Year 2000 issue and estimates that
the majority of testing will be completed by the end of the first quarter of
1999. A number of independent third party assessments have been performed and
others are planned. The Company presently believes that with modifications to
existing software and conversions to new software, the Year 2000 issue can be
mitigated. However, if such modifications and conversions are not made, or are
not completed timely, the Year 2000 issue could cause production interruptions
that could have a material impact on the operations of the Company. The Company
has initiated development of contingency plans and will continue to do so
throughout the program.
 
  The Company has initiated formal communications with a substantial majority
of its significant suppliers and large customers to determine their plans to
address the Year 2000 issue. While the Company expects a successful resolution
of all issues, there can be no guarantee that the systems of other companies
on which the Company's systems rely will be converted in a timely manner, or
that a failure to convert by a supplier or customer, or a conversion that is
incompatible with the Company's systems, would not have a material adverse
effect on the Company. The Company has determined it has no exposure to
contingencies related to the Year 2000 issue for the products it has sold.
 
  The Company has contracts in place with external resources and has allocated
internal resources to reprogram or replace, and test the software for Year
2000 modifications. The Company plans to complete the Year 2000 project within
one year. The total cost of the Year 2000 project is estimated to be $25
million and is being funded through operating cash flows. These estimates have
been verified by independent third party assessment. Of the total project
cost, approximately $11 million is attributable to the purchase of new
software which will be capitalized. The remaining $14 million represents
maintenance and repair of existing systems and will be expensed as incurred.
The Company expects a majority of the costs will be incurred in 1998. As of
September 30, 1998, the Company had incurred and expensed approximately $5
million related to the completed awareness program and assessment project and
the implementation of their remediation plan.
 
  The costs of the project and the date which the Company plans to complete
the Year 2000 modifications are based on management's best estimates, which
were derived utilizing numerous assumptions of future events including the
continued availability of certain resources, third party modification plans
and other factors. However, there can be no guarantee that these estimates
will be achieved and actual results could differ materially from those plans.
Specific factors that might cause such material differences include, but are
not limited to, the availability and cost of personnel trained in this area,
the ability to locate and correct all relevant computer codes and similar
uncertainties.
 
 Euro Conversion
 
  On January 1, 1999, certain member countries of the European Union are
scheduled to irrevocably fix the conversion rates between their national
currencies and a common currency, the "euro", which will become their legal
currency on that date. The participating countries' former national currencies
will continue to exist as denominations of the euro between January 1, 1999
and January 1, 2002. The Company has established a steering committee that is
currently evaluating the business implications of conversion to the euro,
including the need to adapt internal systems to accommodate euro-denominated
transactions. The acquisition of T&N has provided the Company with a strong
knowledge base in which to assist with the conversion. While the Company is
still in various stages of assessment and implementation, the Company does not
expect the conversion to the euro to have a material effect on its financial
condition or results of operations.
 
 Effect of Accounting Pronouncements
 
  In 1997, the Financial Accounting Standards Board issued Statement No. 130
("SFAS No. 130"), "Reporting Comprehensive Income." SFAS No. 130 establishes
standards for the reporting and display of
 
                                     S-50
<PAGE>
 
comprehensive income and its components in a full set of general purpose
financial statements. The Company adopted Statement 130 as of January 1, 1998.
The adoption of this statement had no impact on Federal Mogul's net earnings
(loss) or shareholders' equity. SFAS No. 130 requires foreign currency
translation adjustments and unrealized gains or losses on investments and
derivative instruments to be included in other comprehensive income. Prior to
the adoption of SFAS No. 130 these items were reported as a component of
shareholders' equity.
 
  Total comprehensive income, net of the related estimated tax, was $47.1
million and $15.0 million for the three months ended September 30, 1998 and
1997, respectively, and $22.9 million and $42.4 million for the nine months
ended September 30, 1998 and 1997, respectively.
 
  In June 1998, the Financial Accounting Standards Board issued Statement No.
133, Accounting for Derivative Instruments and Hedging Activities, which is
required to be adopted in years beginning after June 15, 1999. The Company
currently makes minimal use of derivatives. Management does not anticipate,
under current circumstances, that the adoption of the new Statement will have
a significant effect on earnings or the financial position of the Company.
 
SUBSEQUENT EVENTS
 
 Cooper Acquisition
 
  On October 9, 1998, the Company acquired Cooper Automotive, headquartered in
St. Louis, Missouri, with net sales of approximately $1.9 billion for
approximately $1.9 billion cash. See Annex I to this Prospectus Supplement.
 
  In connection with the acquisition of Cooper Automotive, the Company entered
into a $1.95 billion floating rate senior credit agreement with The Chase
Manhattan Bank as agent and a syndicate of lenders. The senior-credit
agreement consists of $1.55 billion in interim loans which will mature on
April 9, 2000 and $400 million of Tranche C Loans which will be repaid in 29
consecutive quarterly installments beginning September 30, 1999.
 
 Announced Sale of T&N Bearings Business
 
  On October 27, 1998, the Company announced that it had entered into an
agreement to sell the T&N Bearing Business to Dana Corporation. The Company
expects to receive proceeds of approximately $430 million and an additional
$13 million of net proceeds from the collection of accounts receivable related
to the sold businesses. The sale of these businesses is in connection with the
Consent Order with the Federal Trade Commission and undertakings with the
governments of the United Kingdom, France and Germany to divest thinwall
bearings, polymer bearings and North American thinwall bearings aftermarket
segments and is subject to regulatory approvals, which are expected in the
fourth quarter of 1998.
 
 Announced Acquisition of Tri-Way
 
  On October 6, 1998, the Company entered into an agreement to acquire Tri-Way
Machine Limited, a privately-owned manufacturer of machines and machining
systems for the world's metal cutting industry headquartered in Windsor,
Ontario, Canada with sales of approximately $35 million.
 
 Revolving Credit Agreement
 
  In October 1998, the Company entered into a $200 million 364-day floating
rate revolving credit agreement with the Chase Manhattan Bank as agent and a
syndicate of lenders.

ASBESTOS LIABILITY AND LEGAL PROCEEDINGS
 
 T&N Asbestos
 
  As of September 30, 1998, the Company has provided $1.292 billion as its
estimate for future costs related to resolving asbestos claims. In the United
States, the Company's subsidiary, T&N plc, and two of T&N plc's U.S.
subsidiaries (the "T&N Companies") are among many defendants named in numerous
court actions alleging personal injury resulting from exposure to asbestos or
asbestos-containing products. T&N is also subject to asbestos-disease
litigation, to a lesser extent, in the United Kingdom and to property damage
litigation based upon asbestos in the United States. Because of the slow onset
of asbestos-related diseases, management anticipates that similar claims will
be made in the future. Although T&N has carefully projected its future
asbestos liability, the assumptions underlying such projections continuously
change and it is therefore not possible to project with certainty the number
of such claims may be made nor the expenditure which may arise therefrom. T&N
has appointed the Center for Claims Resolution ("CCR"), a not-for-profit
coalition of former asbestos producers and sellers, as its representative in
relation to all asbestos-related personal injury claims made against the T&N
Companies in the United States.
 
  Prior to its acquisition, T&N secured a (Pounds)500 million (approximately
$837 million at the September 30, 1998 exchange rate of $1.6742 to 1 pound
sterling) layer of insurance which will be triggered should the aggregate
amount of claims filed after June 30, 1996, where the exposure occurred prior
to that date, exceed (Pounds)690 million (approximately $1,155 million at the
September 30, 1998 exchange rate). At September 30, 1998 the Company has
recorded reserves approximating the insurance level for such claims.
 
  While management believes that reserves are appropriate for anticipated
losses arising from T&N's asbestos related claims, no assurance can be given
that T&N will not be subject to material additional liabilities and
significant additional litigation relating to asbestos. Any such liabilities
or litigation in amounts in excess of the reserves recorded by the Company and
the additional (Pounds)500 million of insurance coverage could have a material
adverse effect on the Company's results of operations, business, liquidity and
financial condition.
 
 Federal-Mogul and Fel-Pro Asbestos
 
  The Company also is one of a large number of defendants in a number of
lawsuits brought by claimants alleging injury due to exposure to asbestos. In
addition, Fel-Pro has been named as a defendant in a large number of product
liability cases involving asbestos, primarily involving gasket or packing
products sold to ship owners. The Company is defending all such claims
vigorously and believes that it and Fel-Pro have substantial defenses to
liability and adequate insurance coverage for defense and indemnity. While the
outcome of litigation cannot be predicted with certainty, management believes
that asbestos claims pending against Federal-Mogul Corporation and Fel-Pro as
of September 30, 1998 will not have a material effect on the Company's
financial position. At September 30, 1998, approximately $3 million in related
reserves has been provided related to asbestos claims pending against Federal-
Mogul Corporation and Fel-Pro.
 
 Other
 
  The Company is involved in various other legal actions and claims, directly
and through its subsidiaries (including T&N and Fel-Pro). After taking into
consideration legal counsel's evaluation of such actions, management is of the
opinion that its outcomes are not reasonably likely to have a material adverse
affect on the Company's financial position, operating results, or cash flows.

RESULTS OF OPERATIONS
 
 Net Sales
 
  Consolidated net sales decreased 11.1% in 1997, primarily due to the
divestiture of certain international retail and wholesale operations, the sale
of the heavy wall bearings operations in Brazil and Germany, the sale of the
United States ball bearing business and continued softness in the North
American aftermarket business. These decreases were partially offset by
certain volume increases primarily in the original equipment business.
 
  Original equipment and aftermarket sales were:

</TABLE>
 
  Original equipment business sales in the Americas were flat in 1997 as
compared to 1996. However, excluding the effect of the Company's divestitures
of its electrical products business in September 1996 and its United States
ball bearing operations in November 1996, net sales increased 15.7% in 1997
compared to 1996. Management attributes this increase primarily to strong 1997
sales in its sealing products division. Sales decreased in 1996 as compared to
1995 due to the sale of the Precision Forged Products Division in April 1995
and the 1996 sales of the electrical products business and the United States
ball bearings manufacturing operations, offset slightly by the acquisition of
Seal Technology Systems Limited in September 1995. Excluding the effect of
these acquisitions and divestitures, sales increased 2.7% in 1996.
 
  International original equipment business sales decreased in 1997 as
compared to 1996 due to the effects of exchange rate fluctuations and the
divestiture of the heavy wall bearing operations in Germany and Brazil
completed on January 2, 1997. Excluding the effects of exchange rate
fluctuations and the divestiture, sales increased 11.7%. Management attributes
this increase to strong customer demand for sputter bearings and Glycodur
material products. In 1996, sales decreased as compared to 1995 due to the
Company's decision to exit some conventional engine bearing business that did
not meet appropriate profitability levels.
 
  North American aftermarket sales decreased in 1997 as compared to 1996 due
to continued weak sales in engine products. Sales decreased in 1996 as
compared to 1995 primarily due to the elimination of special extended payment
terms.
 
  International aftermarket business sales in 1997 as compared to 1996
decreased primarily due to the effects of foreign exchange fluctuations and
the 1997 divestitures of operations in Turkey, Australia, South Africa and
Chile. Excluding the effects of exchange and 1997 divestitures, sales were
essentially flat. In 1996, sales increased as compared to 1995 due to the full
year impact of the acquisitions of Bertolotti in June 1995 and Centropiezas in
September 1995, and to a lesser extent, volume and pricing increases in
Mexico, increased sales volume in Australia and new local operations in
Brazil. These increases were partially offset by $21 million resulting from
the devaluation of the South African rand and a decrease in Venezuela due to a
recession.

<PAGE>
 
  Original equipment sales as a percentage of total sales of the Company
increased to 34.4% in 1997 from 32.8% in 1996, with a corresponding decrease
in aftermarket sales. This shift in 1997 reflects the Company's pursuit and
implementation of its strategy to focus on manufacturing and distribution, as
demonstrated by the previously discussed 1997 divestitures and planned
acquisitions. Previously, as the Company was implementing its retail growth
strategy, original equipment sales as a percentage of total sales of the
Company decreased to 32.8% in 1996 from 34.4% in 1995, with a corresponding
increase in aftermarket sales.
 
 Cost of Products Sold
 
  Cost of products sold as a percent of net sales decreased to 76.5% in 1997
compared to 81.7% for 1996. The decrease is primarily due to the 1997
divestitures of less profitable operations and productivity improvements in
the North American aftermarket and the Americas original equipment business.
In addition, a portion of the 1997 decrease is attributable to 1996 third and
fourth quarter charges incurred of $8 million for customer incentive programs
and $13 million for excess and obsolete inventory. See "--Changes in
Accounting Estimates."
 
  Cost of products sold as a percent of net sales increased to 81.7% in 1996
compared to 80.2% in 1995. The increase is primarily attributable to 1996
third and fourth quarter charges incurred of $8 million for customer incentive
programs and $13 million for excess and obsolete inventory. See "--Changes in
Accounting Estimates."
 
 Selling, General and Administrative Expenses
 
  SG&A expenses as a percent of net sales decreased to 15.8% for 1997 compared
to 16.4% for 1996. In contrast, SG&A expenses as a percent of net sales
increased to 16.4% for 1996 compared to 15.0% for 1995. The 1997 decrease and
1996 increase in SG&A as a percent of net sales is primarily attributable to
bad debt expense, customer incentive programs and environmental and legal
matters (see "--Changes in Accounting Estimates" of $3 million for bad debt
expense, $8 million for customer incentive programs and $9 million for
environmental and legal matters) incurred in the third and fourth quarters of
1996. In addition, the 1996 increase was partially due to higher SG&A costs in
the international aftermarket business.
 
 Changes in Accounting Estimates
 
  In 1996, the Company made certain changes in accounting estimates totaling
$51 million in the third and fourth quarters attributable to 1996 events and
new information becoming available. The changes in accounting estimates
included the following:
 
  Customer Incentive Programs: The increase in the provision for customer
incentive programs of $18 million resulted from contractual changes
implemented primarily in the third and fourth quarters of 1996 with certain
customers, new sales programs, additional customer participation in these
programs and current experience with these programs.
 
  Excess and Obsolete Inventory: Business volume growth remained below
expectations in 1996, principally in the third and fourth quarters, causing a
build up of certain inventories beyond anticipated demand. In addition, the
Company's strategic initiative to focus on its manufacturing business and
divest its retail and certain aftermarket businesses and the sale of the U.S.
ball bearings operations in the fourth quarter adversely affected the utility
of the North American aftermarket business inventory. As a result, the Company
recorded an additional $13 million provision for excess and obsolete
inventory.
 
  Bad Debts: The increase in the bad debt provision of $3 million was
principally attributable to the deterioration of account balances of numerous
low volume customers and termination of business with certain North American
aftermarket customers during 1996.
 
 
                                     S-54
<PAGE>
 
  Environmental and Legal Matters: The environmental and legal provision was
increased by $9 million due to the completion of environmental studies and
related analyses, new issues arising and changes in the status of other legal
matters.
 
  Other: The remaining $8 million of changes in accounting estimates is
comprised of $1 million for changes in the workers' compensation reserve based
on worsening experience in outstanding claims in certain older policy years,
$3 million for interest capitalization, $2 million to adjust estimates of
inventoriable costs and $2 million for other items.
 
 Sales of Businesses
 
  During 1997, the Company received $73.6 million in net cash proceeds from
the sale of its aftermarket operations in South Africa, Australia and Chile,
and its heavy wall bearing operations in Germany and Brazil.
 
  During 1996, the Company received $42.0 million in net cash proceeds from
the sale of its United States ball bearings and electrical products
manufacturing operations.
 
  Except for the sale of the electrical products manufacturing operations,
sales of businesses in 1997 and 1996 relate to assets previously adjusted to
fair value. See "--Adjustment of Assets Held for Sale to Fair Value and Other
Long-Lived Assets." Accordingly, no gain or loss was recognized on the date of
sale related to these transactions. In addition, no gain or loss was
recognized related to the sale of the electrical products manufacturing
operations.
 
  During 1995, the Company sold its equity interest in Westwind Air Bearings,
Limited, recognizing a pretax gain of $16.2 million and its Precision Forged
Products Division for a pretax gain of $7.8 million.
 
 Restructuring Charges
 
  Primarily as a result of the amendments to the 1996 restructuring plan,
described previously in this section, the Company's 1997 operating results
were increased by $23.1 million for the reversal of previously recognized 1996
and 1995 restructuring charges. Offsetting this reversal is a $22.0 million
charge for new 1997 restructuring programs. The net impact on 1997 operations,
as a result of the restructuring activities, was a credit of $1.1 million. The
1997 charge includes $3.1 million for exiting certain European aftermarket
product lines and the related employment reductions, $6.8 million for
termination of certain European administrative and support personnel, $7.5
million for additional exit and severance costs related to the Puerto Rican
retail operations, $2.6 million for consolidation and reconfiguration of the
North American aftermarket service branch network and $2.0 million for other
actions. The Company anticipates that the actions related to the 1997
restructuring plan will be complete by the end of 1998, and that most of the
severance and exit costs will be paid in 1998.
 
  In the fourth quarter of 1996, the Company recognized a restructuring charge
of $57.6 million for costs associated with employee severance, exit and
consolidation costs for 132 international retail operations and 30 wholesale
aftermarket operations, rationalization of European manufacturing operations,
consolidation of lighting products, consolidation or closure of certain North
American warehouse facilities, consolidation of customer support functions in
the United States and streamlining of administrative and operational staff
functions worldwide. The charge consists of $22.7 million for the sale of 132
international retail aftermarket and 30 wholesale aftermarket operations,
$14.7 million for corporate employee severance costs, $7.7 million for the
rationalization of European manufacturing operations, $5.3 million for
consolidation or closure of certain North American warehouse facilities, $2.8
million for consolidation of customer support functions in the United States,
$2.5 million for closure of the Leiters Ford facility and $1.9 million for
other miscellaneous actions, including the consolidation of the European
aftermarket management function into the European manufacturing headquarters.
The Company's 1997 progress and actual implementation of the 1996
restructuring plan resulted in 1997 operating results being increased by $20.8
million for severance and $1.4 million of exit and
 
                                     S-55
<PAGE>
 
consolidation costs being reversed. The Company expects to pay out most of the
remaining 1996 severance and exit costs in 1998.
 
  Results of operations in the second and fourth quarters of 1995 include
restructuring charges of $6.1 million and $20.8 million, respectively. These
charges were comprised of $20.1 million for employee severance and $6.8
million for exit costs and consolidation of certain facilities. The workforce
reductions and consolidation of facilities were completed as of December 31,
1996. Operating results for 1997 were increased by $0.9 million relating to
1995 exit costs being reversed. The Company expects to pay out the remaining
1995 exit costs in 1998.
 
 Reengineering and Other Related Charges
 
  Operating results for 1997 include a credit of $1.6 million relating to 1996
reengineering and other related charges being reversed.
 
  In 1996, the Company initiated an extensive effort to strategically review
its businesses and focus on its core competencies: manufacturing, engineering
and distribution. As a result of this process, the Company recognized a charge
of $11.4 million for professional fees and personnel costs related to the
strategic review of the Company and changes in management and related costs.
 
  In 1995, the Company recognized a charge of $13.9 million for reengineering
and other costs. These costs included $7.0 million for professional fees and
personnel costs, and $6.9 million primarily for certain other non-recurring
costs relating to brand consolidation at the customer level of the Company's
Federal-Mogul(R), TRW(R) and Sealed Power(R) branded engine parts.
 
 Adjustment of Assets Held for Sale to Fair Value and Other Long-Lived Assets
 
  The Company continually reviews all components of its businesses for
possible improvement of future profitability through acquisition, divestiture,
reengineering or restructuring. The Company also continually reviews and
updates its impairment reserves related to the divestiture of its remaining
international retail aftermarket operations and adjusts the reserve components
to approximate their net fair value.
 
  In the fourth quarter of 1997, the Company recognized a charge of $2.4
million to write-down of certain long-lived assets to fair value. As of
December 31, 1997, assets held for sale primarily include retail aftermarket
operations in Puerto Rico, Ecuador, Venezuela and Panama. By the end of the
first quarter of 1998, the Company expects to have successfully exited all of
its retail aftermarket businesses, except for Puerto Rico where the Company
continues to seek a buyer.
 
  During 1996, management designed a restructuring plan to aggressively
improve the Company's cost structure, streamline operations and divest the
Company of underperforming assets. As part of this plan, the Company decided
to sell 132 international retail aftermarket operations, sell or restructure
30 wholesale aftermarket operations and consolidate a North American
manufacturing operation. The carrying value of assets held for sale was
reduced to fair value based on estimates of selling values less costs to sell.
Selling values used to determine the fair value of assets held for sale were
determined using market prices (i.e., valuation multiples) of comparable
companies from other 1996 transactions. The resulting adjustment of $148.5
million to reduce assets held for sale to fair value was recorded in the
fourth quarter of 1996. As previously described in this section, the Company
made significant progress related to the implementation of the 1996
restructuring plan. Also in 1996, based upon the final sale, the Company
recognized an additional writedown of $2.8 million to the net asset value of
the United States ball bearings operations. In 1995, the Company decided to
sell the ball bearings operations and reduced the carrying value by $17.0
million to record assets held for sale at fair value.
 
  In 1995, the Company also decided to sell its heavy wall bearing operations
in Germany and Brazil. The Company estimated the fair value of the businesses
held for sale based on discussions with prospective buyers,
 
                                     S-56
<PAGE>
 
adjusted for selling costs. The Company reduced its carrying value by $17
million to record assets held for sale at fair value. The heavy wall bearing
operations were sold in January 1997 for net proceeds of $8.9 million, which
approximated the carrying value of the assets at December 31, 1996.
 
  In addition, in 1995, the Company reduced the carrying value of certain
other impaired long-lived assets by $17.8 million to record them at fair
value. No further fair value adjustments were recorded for these assets in
1996 or 1997.
 
  Net sales for all assets held for sale and adjusted to fair value
approximated $114 million, $335 million, and $322 million in 1997, 1996 and
1995, respectively. Net sales for the remaining retail aftermarket operations
held for sale at December 31, 1997 approximated $44 million, $48 million and
$22 million in 1997, 1996 and 1995, respectively.
 
 Interest Expense
 
  Interest expense decreased $10.6 million in 1997 to $32.0 million. The
decrease was primarily due to a $188 million reduction of debt which resulted
from improvements in working capital and the sale of the South African and
Australian businesses. Although the Company decreased its debt by $104 million
from 1995 to 1996, interest expense increased $5.3 million in 1996 primarily
due to a higher average debt level than in 1995. Excluding the U.S. and
European revolving credit facilities, which were classified as short-term debt
during 1996 and as long-term debt during 1995, the weighted average interest
rate for short-term debt increased to 10.9% for 1996 from 9.5% for 1995. The
interest rate on the U.S. and European revolving credit facilities at December
31, 1996 and 1995 was 6.1% and 6.2%, respectively.
 
 Income Taxes
 
  At December 31, 1997, the Company had deferred tax assets, net of a $44.4
million valuation allowance, of $140.5 million and deferred tax liabilities of
$75.9 million.
 
  The net deferred tax asset of $64.6 million included the tax benefits of
$58.2 million related to the Company's postretirement benefit obligation at
December 31, 1997. The Company expects to realize the benefits associated with
this obligation over a period of 35 to 40 years.
 
  The difference between the 1997 effective income tax rate and the statutory
tax rate is principally due to utilization of losses on foreign investment and
an income tax benefit related to the sales of the South African and Australian
businesses (refer also to Note 16 of the Consolidated Financial Statements).
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Cash flow from operations of $215.7 million in 1997 increased significantly
during 1997 primarily due to increased earnings. The Company also reduced
inventory from operations by $59.9 million in 1997. Inventory reductions in
the North American aftermarket business were primarily responsible for the
decrease. The decrease in North America aftermarket inventory is attributable
to reduced lead times while still maintaining availability of products and
modifying safety stock levels.
 
  Cash flow used by investing activities of $5.5 million in 1997 include $28.1
million for the British pound currency option, described later in this
section, and $2.4 million for other professional fees paid in anticipation of
the T&N acquisition. In addition, cash flows used by investing activities
include the receipt of $73.6 million in net proceeds from the 1997
divestitures.
 
  Cash flow from 1997 financing activities was $298.1 million, an increase of
$420.9 million from 1996. The following events were primarily responsible for
the net increase for 1997:
 
 
                                     S-57
<PAGE>
 
  Issuance of Preferred Securities of Affiliate: In December 1997, the
Company's financing trust completed a $575 million private issuance of
11,500,000 shares of 7% Trust Convertible Preferred Securities. The
convertible preferred securities are redeemable at the Company's option, in
whole or in part, on or after December 6, 2000. All outstanding convertible
securities are required to be redeemed no later than December 1, 2027.
 
  Issuance of Senior Notes: In April 1997, the Company issued a fully
subscribed $125 million debt offering of 8.8% senior notes due April 2007.
Proceeds from the offering were used to reduce the Company's short-term debt
and the early extinguishment of the private placement debt.
 
  Extinguishment of Private Placement Debt: In the second quarter of 1997, the
Company retired $64.7 million in private placement debt. The early retirement
of this debt eliminated high coupon debt and potentially restrictive covenants
giving the Company greater financial flexibility in the future. In addition,
the early retirement of this debt involved a make whole payment that resulted
in a $4.1 million pretax ($2.6 million after tax) extraordinary loss.
 
  Accounts Receivable Securitization: During 1997, the Company replaced an
existing accounts receivable securitization program with a new program which
provides up to $100 million of financing. On an ongoing basis, the Company
sells certain accounts receivable to a subsidiary of the Company, which then
sells such receivables, without recourse, to a master trust. Amounts sold
under this arrangement were $63.2 million as of December 31, 1997, and have
been excluded from the balance sheet. During 1997, cash payments totaling
$31.8 million were made to the master trust related to the Company's accounts
receivable securitization. These cash payments effectively increased the
Company's investment in the accounts receivable securitization.
 
  Multicurrency Revolver: In June 1997, the Company entered into a new $350
million multicurrency revolving credit facility with a consortium of
international banks which matures in June 2002. The multicurrency revolving
credit facility replaced the existing U.S. and European revolving credit
facilities. The multicurrency revolving credit facility contains restrictive
covenants that, among other matters, require the Company to maintain certain
financial ratios. As of December 31, 1997, there were no borrowings
outstanding against the multicurrency revolving credit facility.
 
  In December 1997, the Company entered into a $3.25 billion committed bank
facility with a reputable financial institution related to the T&N
acquisition. The facility provides for up to $2.75 billion of senior debt and
up to $500 million of subordinated debt. Because this facility was contingent
upon the acquisition of T&N, no amounts were outstanding as of December 31,
1997. Certain fees relating to this facility have been incurred and paid as of
December 31, 1997.
 
  The Company believes that cash flow from operations will continue to be
sufficient to meet its ongoing working capital requirements.
 
ENVIRONMENTAL MATTERS
 
  The Company is a party to lawsuits filed in various jurisdictions alleging
claims pursuant to the Comprehensive Environmental Response Compensation and
Liability Act of 1980 ("CERCLA") or other state or federal environmental laws.
In addition, the Company has been notified by the Environmental Protection
Agency and various state agencies that it may be a potentially responsible
party ("PRP") for the cost of cleaning up certain other hazardous waste
storage or disposal facilities pursuant to CERCLA and other federal and state
environmental laws. PRP designation requires the funding of site
investigations and subsequent remedial activities. Although these laws could
impose joint and several liability upon each party at any site, the potential
exposure is expected to be limited because at all sites other companies,
generally including many large, solvent public companies, have been named as
PRPs. In addition, the Company has identified certain present and former
properties at which it may be responsible for cleaning up environmental
contamination.
 
  The Company is actively seeking to resolve these matters. Although difficult
to quantify based on the complexity of the issues, the Company has accrued the
estimated cost associated with such matters based upon
 
                                     S-58
<PAGE>
 
current available information from site investigations and consultants. The
environmental and legal reserve was approximately $11 million at December 31,
1997 and $12 million at December 31, 1996. Management believes that such
accruals will be adequate to cover the Company's estimated liability for its
exposure in respect of such matters.
 
FOREIGN CURRENCY AND COMMODITY CONTRACTS
 
  In connection with the T&N acquisition, the Company purchased for $28.1
million a foreign currency option with a notional amount of $2.5 billion to
cap the effect of potential unfavorable fluctuations in the British pound/U.S.
dollar exchange rate. The cost of the option and its change in fair value has
been reflected in the results of operations in the fourth quarter of 1997. At
December 31, 1997, the Company has recognized a net loss on this transaction
of $10.5 million.
 
  The Company is subject to exposure to market risks from changes in foreign
exchange rates and raw material price fluctuations, derivative financial
instruments are utilized by the Company to reduce those risks. Except for the
British pound currency option discussed above, the Company does not hold or
issue derivative financial instruments for trading purposes.
 
  Other than the British pound currency option discussed above, the Company
does not have foreign exchange forward or currency option contracts
outstanding at December 31, 1997.
 
  In the first quarter of 1998, the Company settled the British pound currency
option, resulting in a pretax loss of $17.3 million. Also in the first quarter
of 1998, the Company entered into a forward contract to purchase 1.5 billion
British pounds for a notional amount approximating $2.45 billion. The forward
contract expires in the first quarter of 1998.
 
OTHER MATTERS
 
 Conversion of Series D Convertible Exchangeable Preferred Stock
 
  In August 1997, the Company announced a call for the redemption of all its
outstanding $3.875 Series D Convertible Exchangeable Preferred Stock. These
preferred shareholders elected to convert each preferred share into 2.778
shares of Common Stock. The Company issued 4.4 million shares of Common Stock
in exchange for all of the outstanding Series D convertible exchangeable
preferred stock.
 
 Customer Reorganization
 
  On February 2, 1998, APS Holding Corporation ("APS") filed for
reorganization protection under Chapter 11 of the United States Bankruptcy
Code. As of the date of the Chapter 11 filing, the Company's total receivables
with APS approximated $10 million. APS has received a capital line of credit
from a reputable financial institution and is continuing business operations.
The Company continues to do business with APS on a cash in advance basis.
Although difficult to quantify based upon the uncertainty of the financial
condition of APS, the Company believes that net uncollectible receivables, if
any, from APS will be immaterial.
 
  In addition, APS is a customer of Fel-Pro. The Company believes that the
allowance established by Fel-Pro prior to the acquisition of Fel-Pro related
to receivables from APS is adequate to cover any uncollectible amounts.

  On March 6, 1998, Federal-Mogul completed its cash offer to acquire all
outstanding common stock of T&N for 260 pence per share. Total consideration
paid was (Pounds)1.4636 billion ($2.4164 billion, converted at a blended
exchange rate of 1 pound sterling to 1.6510 U.S. dollars). In connection with
securing regulatory approvals for the acquisition of T&N, Federal Mogul agreed
subsequently to divest certain assets, consisting principally of T&N's
thinwall and dry bearings (polymer bearings) operations. See "Business--
Reorganization." These assets are a subset of the operations T&N included in
its bearings product group and the discussion below of such product group does
not, therefore, directly correspond to the assets to be divested (which are
referred to elsewhere in this Offering Memorandum as the "T&N Bearings
Business").

  The following discussion is based upon the T&N Financial Statements
incorporated herein by reference, which have been prepared in conformance with
U.K. GAAP. U.K. GAAP differ in certain significant respects from U.S. GAAP.
The significant differences between U.S. GAAP and U.K. GAAP as they relate to
T&N are summarized in Note 29 to the T&N Financial Statements. (The T&N
Financial Statements may be found in the Company's Form 8-K filed April 7,
1998).
 
RESULTS OF OPERATIONS
 
 Turnover (Net Sales)
 
  T&N's consolidated turnover excluding associated undertakings (hereinafter
referred to as net sales) decreased by 8.0% in 1997. The 1997 decrease was
primarily due to the effects of adverse foreign exchange fluctuations, 1997
divestitures and the full year impact of 1996 divestitures. These decreases
were partially offset by the 1997 acquisition of Metal Leve, Inc., which
expanded T&N's product offerings in piston-related products, and certain
volume improvements for continuing businesses. Excluding 1997 acquisitions
(which added (Pounds)30 million to 1997 net sales) and the impact of
divestitures, 1997 net sales decreased 4.4% as compared to 1996.
 
  The primary source of the foreign exchange fluctuation impact on T&N in 1997
was the continued appreciation of the pound sterling in relation to other
European currencies (and, to a lesser extent, the U.S. dollar) through the
year. This appreciation resulted in an adverse currency translation effect
upon overseas earnings and erosion of margins on exports billed in foreign
currency. These effects were partially offset by reduced expense for materials
imported into the U.K. Excluding the effects of (Pounds)153 million in adverse
foreign currency fluctuations and acquisitions, net sales from continuing
operations increased by approximately 4.0%.
 
  Net sales by market were:

  Decreases in sealing products net sales were primarily attributable to
German and French businesses. Piston products net sales, which declined by
0.3% in 1997 as compared with 1996, were affected by the acquisition of Metal
Leve, Inc. (excluding that acquisition, piston products net sales from
continuing operations decreased 5.2%).
 
  During 1997, 1996 and 1995, T&N divested certain non-core businesses with
net sales of (Pounds)34.8 million, (Pounds)141.6 million and (Pounds)314.5
million. These divestitures included the disposition of T&N's entire
construction materials and engineering products business.

 Cost of Sales
 
  Cost of sales as a percentage of net sales was 71.8%, 72.5% and 72.1% for
1997, 1996 and 1995, respectively. The 1997 acquisition and 1997 and 1996
divestitures had an immaterial impact on cost of sales as a percentage of net
sales. Excluding the impact of 1995 divestitures, cost of sales as a
percentage of net sales was 71.3% in 1995.
 
 Federal-Mogul Bid Related Costs
 
  T&N incurred (Pounds)10 million of costs in 1997 related to the acquisition

ASBESTOS
 
  In the U.S., T&N plc and two of its U.S. subsidiaries (the "T&N Companies")
are among many defendants named in numerous court actions alleging personal
injury resulting from exposure to asbestos or asbestos-containing products.
T&N plc is also, to a lesser extent, subject to asbestos-disease litigation in
the U.K. and to property damage litigation in the U.S. Because of the slow
onset of asbestos-related diseases, management anticipates that similar claims
will be made in the future. It is not known how many such claims may be made
nor the expenditure which may arise therefrom. See "Risk Factors--T&N's
Asbestos Liability."
 
 
                                     S-61
<PAGE>
 
  In 1996, T&N secured a (Pounds)500 million layer of insurance which will be
triggered should the aggregate cost to resolve claims notified after June 30,
1996, where the exposure occurred prior to that date (incurred but not
reported, or "IBNR," claims), exceed (Pounds)690 million. For additional
information regarding asbestos-related liabilities and reserves, see the Pro
Forma Financial Statements and Notes 19 and 28 to the T&N Financial Statements
(which are found in the Company's Form 8-K filed April 7, 1998).
 
 Asbestos Charges Recognized in 1996 and 1997
 
  T&N recognized a charge to establish provisions for IBNR claims for the year
ended December 31, 1996 in the amount of (Pounds)323 million ((Pounds)550
million on an undiscounted basis); T&N also recognized a second charge in the
amount of (Pounds)50 million related to the risk that U.S. courts would reject
a class action settlement to which the T&N Companies were party (in Georgine
et al. v. Amchem et al.). This settlement was ultimately rejected by the U.S.
Supreme Court in 1997 and some increase in new IBNR claims filed has resulted.
T&N also recognized a (Pounds)50 million charge in 1996 for claims notified
and outstanding as of June 30, 1996. In addition, T&N recorded the (Pounds)92
million cost of the (Pounds)500 million layer of insurance in 1996, and the
premium was paid in 1997. T&N recognized no additional provisions relating to
asbestos in 1997.
 
 Asbestos-Related Payments in 1996 and 1997
 
  T&N paid (Pounds)149.4 million for asbestos-related claims, including the
(Pounds)92 million insurance premium, during 1997 and (Pounds)64.8 million in
1996.
 
RELEASE OF PROVISION/(PROVISION AGAINST) FIXED ASSET INVESTMENTS:
KOLBENSCHMIDT COSTS
 
  In March 1995, T&N entered into option arrangements for 1,345,452 shares of
Kolbenschmidt AG ("KS"), which represented approximately 49% of the
outstanding share capital of KS. In 1995, T&N recognized a charge of
(Pounds)19.5 million related to the creation of provisions relating to the
reduction of the value of fixed asset investments (the Kolbenschmidt options).
 
  In 1996, KS issued nine shares for each share already outstanding such that
the option arrangements increased to 13,454,520 shares. In December 1996,
options over 6,727,260 shares expired and T&N recognized a (Pounds)23.4
million related charge.
 
  In 1997, Commerzbank subsequently sold the KS shares and, subject to the
option arrangement, T&N received part of the proceeds and recognized a gain of
(Pounds)13.2 million, accordingly. In addition, T&N received an offer to
purchase its remaining interest in KS, and, as a result, T&N recognized in
1997 an additional (Pounds)19.2 million gain (the sale of such remaining
interest occurred in March 1998). (See Note 4 to the T&N Financial Statements,
which may be found in the Company's Form 8-K filed April 7, 1998.)
 
NET INTEREST PAYABLE AND SIMILAR CHARGES--GROUP
 
  Net interest payable and similar charges--group (hereinafter referred to as
interest expense or interest income) was (Pounds)28.4 million in 1997 as
compared to (Pounds)26.8 million in 1996.
 
  Gross interest expense was (Pounds)39.3 million in 1997 as compared to
(Pounds)32.5 million in 1996. The 1997 increase of (Pounds)6.8 million in
gross interest expense is primarily attributable to higher interest rates,
partially offset by lower average borrowings arising from continued
improvements in working capital. In addition, 1997 gross interest expense
includes (Pounds)2.5 million for the amortization of T&N's discounted asbestos
provision.
 
  Gross interest income was (Pounds)10.9 million in 1997 as compared to
(Pounds)5.7 million in 1996. The 1997 increase was primarily attributable to
earnings on funds reserved for asbestos liabilities.
 
  Net interest expense in 1996 decreased (Pounds)9.0 million as compared to
1995. The 1996 decrease was primarily due to lower debt levels and interest
rates as compared with 1995.

TAX ON PROFIT/(LOSS) ON ORDINARY ACTIVITIES (INCOME TAXES)
 
  Income tax expense was (Pounds)62.8 million in 1997 resulting in an
effective tax rate of 33.0% compared with the statutory U.K. corporation tax
of 31.5%. The difference between the effective tax rate and U.K. corporation
rate is attributable to a number of factors, none of which are material.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Cash flows from operating activities (including asbestos) were (Pounds)111.4
million in 1997 as compared to (Pounds)215.7 million in 1996. The 1997
decrease is primarily attributable to the strong sales performance and the
increase in orders for 1998 shipment in the fourth quarter of 1997 which
limited T&N's ability to reduce debtors (accounts receivable) and stocks
(inventory) as compared to the 1996 reductions.
 
  Capital expenditures in 1997 were (Pounds)103.9 million compared to
(Pounds)114.3 million in 1996. The 1997 decrease is primarily attributable to
the disposal of certain businesses and foreign currency fluctuations.
 
  Proceeds from business disposals were (Pounds)75.7 million in 1997 compared
to (Pounds)74.8 million in 1996.
 
  T&N paid (Pounds)32.6 million in 1997 for the acquisition of businesses. The
most significant acquisition in 1997 was that of Metal Leve, Inc., a
manufacturer of articulated pistons based in the United States.
 
LEGAL MATTERS
 
  In addition to the asbestos litigation, T&N is engaged in various actions
arising in the ordinary course of its business. Management is of the opinion
that the outcome of these matters will not have a material adverse effect on
T&N's financial condition.
 
FOREIGN CURRENCY AND COMMODITY CONTRACTS
 
  T&N was subject to exposure to market risks from changes in foreign exchange
rates and raw material price fluctuations. Derivative financial instruments
were utilized by T&N to reduce those risks. T&N does not hold or issue
derivative financial instruments for trading purposes.

    YEAR ENDED DECEMBER 31, 1997 COMPARED WITH YEAR ENDED DECEMBER 31, 1996
  AND YEAR ENDED DECEMBER 31, 1996 COMPARED WITH YEAR ENDED DECEMBER 31, 1995
 
  On January 9, 1998, Fel-Pro's owners signed an agreement to sell the Fel-Pro
group, consisting of Fel-Pro Inc., certain operating businesses and holding
companies affiliated with Fel-Pro Inc. and certain real estate owned by Fel-
Pro Inc. or its affiliates to Federal-Mogul. The transaction closed on
February 24, 1998, at which time Federal-Mogul acquired all equity interests
in the specified Fel-Pro entities for approximately $717 million, which
included 1,030,325.6 shares of Series E Stock (as hereinafter defined) with an
imputed value of $225 million and approximately $492 million in cash. Federal-
Mogul recently sold the chemical manufacturing operations acquired with Fel-
Pro (representing approximately $32.8 million of Fel-Pro's 1997 net sales and
$2.6 million of Fel-Pro's 1997 net income).
 
RESULTS OF OPERATIONS
 
 Net Sales
 
  Fel-Pro's consolidated net sales increased 9.2% in 1997 as compared to 1996,
primarily due to volume increases from new and existing customers in the
aftermarket business. Consolidated net sales increased 15.5% in 1996 as
compared to 1995 primarily due to volume increases from new and existing
customers in the

aftermarket business, as well as the acquisition of TCI, a high performance
transmission and torque converter manufacturer in December of 1995 and the
acquisition of Korody-Colyer ("KC") in October of 1995 for $12.3 million and
$7.1 million, respectively. Excluding the effect of the acquisitions of TCI
and KC, Fel-Pro's net sales increased 6.4% in 1995.

  Original equipment sales increased 7.0% in 1997 as compared to 1996 due to
volume increases of gaskets for the heavy duty market partially offset by
volume decreases in the automotive market related to the end of certain
products' life cycles. Fel-Pro's original equipment sales increased 3.0% in
1996 as compared to 1995.
 
  Aftermarket sales in the United States and Canada increased 6.0% in 1997 as
compared to 1996 primarily due to new customer business. Sales increased 14.8%
in 1996 as compared to 1995 due to the following: (i) volume increases from
new and existing customers; (ii) the December 1995 acquisition of TCI; and
(iii) the full year impact of the October 1995 acquisition of KC.
 
  Excluding the effect of the 1995 acquisitions, Fel-Pro's aftermarket sales
in the United States and Canada increased 7.8% in 1996.
 
  International aftermarket sales increased 23.9% in 1997 as compared to 1996
primarily due to volume increases in heavy duty diesel engine parts.
International aftermarket sales increased 38.0% in 1996 as compared to 1995
primarily due to volume increases in heavy duty engine parts which included
the full year impact of the October 1995 KC acquisition. Excluding the effect
of the acquisition, international aftermarket sales increased 22.7% in 1996.
 
 Cost of Goods Sold
 
  Cost of goods sold as a percent of net sales was flat in 1997 at 54.8% as
compared to 1996. Cost of goods sold as a percent of net sales decreased to
54.8% in 1996 compared to 56.0% in 1995. The decrease is primarily
attributable to cost reductions and productivity improvement efforts.
 
 Operating Expenses
 
  Operating expenses as a percentage of net sales decreased to 35.5% in 1997
compared to 36.4% in 1996. The 1997 decrease is primarily attributable to Fel-
Pro's increases in sales volume exceeding the corresponding increase in
variable operating expenses. Operating expenses as a percentage of net sales
were relatively flat in 1996 as compared to 1995.
 
 Income Taxes
 
  Fel-Pro's $15.7 million deferred tax assets at December 29, 1996 were
written off in 1997 due to the conversion from C corporation status to
Subchapter S corporation status of its principal operating company effective
1997.
 
 
                                     S-64
<PAGE>
 
  The difference between Fel-Pro's effective income tax rate and the statutory
tax rate is also due to the conversion of Fel-Pro's principal operating
company from C corporation status to Subchapter S corporation status in 1997.
In 1997, upon conversion of the principal operating company (Felt Products
Mfg. Co. and subsidiaries) to Subchapter S corporation status and in addition
to writing off the deferred tax assets, Fel-Pro recognized $7.4 million of
expense associated with LIFO recapture taxes.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Cash flow from operations of $51.7 million in 1997 increased significantly
during 1997 primarily due to the write-off of $16.8 million in deferred taxes
and an $11.3 million improvement in accounts receivable over the prior year.
 
  Cash flow used by investing activities of $18.5 million in 1997 include $3.5
million for the September purchase of certain operating assets of Biwax
Corporation. Capital expenditures were $18.3 million in 1997, primarily for
enhanced manufacturing capabilities and process improvements. Partially
offsetting these outflows were $3.9 million related to proceeds from available
for sale marketable securities.
 
  Cash flows used by 1997 financing activities were $33.2 million, a decrease
of $32.7 million from 1996. The 1997 decrease was primarily due to lower
amounts provided to fund Fel-Pro's affiliates.
 
LEGAL MATTERS
 
  Fel-Pro is engaged in various legal actions arising in the ordinary course
of its business. Management, after taking into consideration legal counsel's
evaluation of such actions, is of the opinion that it has adequate legal
defenses or insurance coverage and that the outcome of these matters will not
have a material adverse effect on Fel-Pro's financial position.
 
OTHER MATTERS
 
 Customer Bankruptcy Reorganization
 
  On February 2, 1998, APS filed for reorganization protection under Chapter
11 of the United States Bankruptcy Code.
 
  Fel-Pro believes that the allowance established related to receivables from
APS is adequate to cover any uncollectible amounts.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
1997 CREDIT AGREEMENT
 
  In connection with the acquisitions of T&N and Fel-Pro, Federal-Mogul
entered into a $2.75 billion floating rate senior credit agreement (the "1997
Credit Agreement") (consisting of a $2.35 billion term loan facility, which
was reduced to $2.275 billion effective as of March 11, 1998 and a $400
million revolving loan facility) and a $500 million floating rate senior
subordinated credit agreement (the "Senior Subordinated Credit Agreement"),
each with Chase as agent and a syndicate of lenders. The entire amount of the
senior term loan facility and the entire amount of the senior subordinated
credit facility were drawn down. The senior term loan facility consisted of
(i) interim loans (the "Interim Loans") in the aggregate amount of $925
million maturing September 12, 1999; (ii) Tranche A loans (the "Tranche A
Loans") in the aggregate amount of $600 million; and (iii) Tranche B loans
(the "Tranche B Loans" and, together with the Interim Loans and the Tranche A
Loans, the "1997 Term Loans") in the aggregate amount of $750 million.
Federal-Mogul used the proceeds of the sale of 10,537,093 shares of its Common
Stock in an underwritten public offering in June 1998 as well as the proceeds
from the issuance of notes in the principal amount of $1 billion, in June
1998, to prepay the entire outstanding $500 million principal amount of the
loans under the Senior Subordinated Credit Agreement and the outstanding $925
million principal amount of the Interim Loans as well as to reduce the
outstanding balances of the Tranche A Loans and the Tranche B Loans by $144.4
million and $7.3 million, respectively.
 
  The Tranche A Loans mature on December 31, 2003 and are to be repaid in 20
quarterly installments commencing March 31, 1999, the amount of each quarterly
installment being $19 million in 1999 and 2000, $30 million in 2001 and $41
million in 2002 and 2003. The Tranche B Loans mature on December 31, 2005 and
are to be repaid in 28 quarterly installments commencing March 31, 1999, the
amount of each quarterly installment being $1.25 million during the period
from 1999 to 2003, inclusive, $75 million in 2004 and $106.25 million in 2005.
As of June 30, 1998, the outstanding principal amounts of the Tranche A Loans
and the Tranche B Loans were $455.6 million and $742.7 million, respectively.
 
  Under the 1997 Credit Agreement, Federal-Mogul may borrow up to an aggregate
amount of $400 million outstanding at any time in revolving credit loans (the
"1997 Revolving Credit Loans"), which are available for working capital and
other general corporate purposes for a period of six years commencing March
12, 1998. Up to $120 million of Revolving Credit Loans may be borrowed in
currencies other than U.S. dollars.
 
  Indebtedness under the 1997 Credit Agreement bears interest at a floating
rate based upon, at Federal-Mogul's option, either (i) the higher of the prime
rate of Chase and 0.5% in excess of the overnight federal funds rate ("Base
Rate"), plus (in each case) a margin, or (ii) the average of the offering
rates of certain banks in the London interbank eurodollar market for U.S.
dollar deposits ("Eurodollar Rate"), plus a margin. The applicable margins
depend upon Federal-Mogul's consolidated leverage ratio: (i) in the case of
Base Rate loans, the applicable margin will vary between 0% and 0.5% for 1997
Revolving Credit Loans, 0.0% and 1.0% for Tranche A Loans and 0.5% and 1.25%
for Tranche B Loans, and (ii) in the case of Eurodollar Rate loans, the
applicable margin will vary between 0.75% and 1.5% for 1997 Revolving Credit
Loans, 1.0% and 2% for Tranche A Loans and 1.5% and 2.25% for Tranche B Loans.
 
 Collateral and Guarantees
 
  Federal-Mogul, its U.S. subsidiaries and certain of its foreign subsidiaries
have pledged or are in the process of pledging 100% (or, in the case of the
stock of certain foreign subsidiaries, 65%) of the capital stock of certain of
their subsidiaries and certain intercompany loans to secure the 1997 Term
Loans and 1997 Revolving Credit Loans. Part of such collateral also secures
certain existing public debt of Federal-Mogul and certain other indebtedness,
and all such collateral will be released when Federal-Mogul has obtained
investment grade ratings for its debt or met a certain leverage ratio. In
addition, the U.S. subsidiaries and certain foreign subsidiaries of Federal-
Mogul have guaranteed the 1997 Term Loans and 1997 Revolving Credit Loans and
certain other indebtedness. The stock of certain other subsidiaries of
Federal-Mogul may be pledged in the future to secure the 1997 Term Loans and
the 1997 Revolving Credit Loans and other indebtedness, and one or more of
such other subsidiaries may also in the future guarantee such indebtedness.

<PAGE>
 
 Certain Covenants
 
  The 1997 Credit Agreement contains certain covenants that restrict or limit
Federal-Mogul from taking various actions, including, subject to specified
exceptions, (i) the granting of additional liens, (ii) the incurrence of
additional indebtedness, (iii) the granting of additional guarantees, (iv)
mergers, acquisitions and other fundamental corporate changes, (v) the sale of
assets, (vi) the payment of dividends and other restricted payments, (vii) the
making of investments, (viii) optional prepayments of certain debt and the
modification of debt instruments, (ix) entering into sale and leaseback
transactions, (x) the imposition of restrictions on any subsidiary's ability
to make payments, loans or advances to Federal-Mogul, (xi) entering into a new
debt agreement with more restrictive covenants and (xii) transactions with
affiliates. The 1997 Credit Agreement also contains certain financial
covenants that require Federal-Mogul to meet and maintain certain financial
tests and minimum ratios, including a minimum cash flow coverage ratio, a
minimum consolidated leverage ratio and a minimum consolidated net worth test.
Federal-Mogul may elect to have a different set of covenants apply to the 1997
Credit Agreement, which will require lower leverage but otherwise will be less
restrictive. Prior to the election by Federal-Mogul of alternative covenants,
the 1997 Credit Agreement prohibits payment of dividends on Federal Mogul
Common Stock in excess of the rate of $0.12 per quarter.
 
 Events of Default
 
  The 1997 Credit Agreement contains customary events of default, including
nonpayment of principal, interest or fees, violation of covenants, inaccuracy
of representations or warranties in any material respect, cross acceleration
and cross default to certain other indebtedness, bankruptcy, noncompliance
with certain provisions of ERISA, material judgments, failure of the
collateral documents or subordination provisions, and change of control. The
occurrence of any of such events could result in acceleration of Federal-
Mogul's obligations under the 1997 Credit Agreement and foreclosure on
collateral securing the 1997 Term Loans and 1997 Revolving Credit Loans.
 
 Fees
 
  Federal-Mogul is currently paying a facility fee on the used and unused
portion of each lender's commitment to make 1997 Revolving Credit Loans at the
rate of 0.25% to 0.5% per annum, depending on Federal-Mogul's leverage ratio.
In addition, Federal-Mogul paid customary fees to Chase and reimbursed
customary expenses in connection with the closing of the 1997 Credit Agreement
and the Senior Subordinated Credit Agreement.
 
1998 TERM LOAN AGREEMENT AND 1998 364-DAY REVOLVING CREDIT AGREEMENT
 
  In connection with its acquisition of Cooper Automotive, Federal-Mogul has
entered into (i) a $1.95 billion floating rate senior credit agreement (the
"Term Loan Agreement"), consisting of a senior term loan facility, and (ii) a
$200 million 364-day floating rate revolving credit agreement (the "Revolving
Credit Agreement," together with the Term Loan Agreement, the "1998 Credit
Agreements" and, together with the 1997 Credit Agreement, the "Credit
Agreements"), each with Chase as agent and a syndicate of lenders. The senior
term loan facility consists of (i) interim loans (the "New Interim Loans") in
the aggregate amount of $1.55 billion, and (ii) Tranche C loans (the "Tranche
C Loans" and, together with the New Interim Loans, the "1998 Term Loans") in
the aggregate amount of $400 million.
 
  Under the Term Loan Agreement, the New Interim Loans will mature April 9,
2000 and are to be payable in full on that date. The Tranche C Loans will
mature September 30, 2006 and are to be repaid in 29 consecutive quarterly
installments commencing September 30, 1999, the first 28 of which shall be
equal to $250,000 and the final installment of which shall be equal to $393
million.
 
  Under the Revolving Credit Agreement, Federal-Mogul may borrow up to an
aggregate amount of $200 million outstanding at any time in revolving credit
loans (the "1998 Revolving Credit Loans"), which will be available for working
capital and other general corporate purposes for a period of 364 days
commencing October 9, 1998.
 
                                     S-67
<PAGE>
 
  Indebtedness under the 1998 Credit Agreements bears interest at a floating
rate based upon, at Federal-Mogul's option, either (i) the Base Rate, plus a
margin of 1.25% for the New Interim Loans, a margin of 1.75% for the Tranche C
Loans, and a margin based on Federal-Mogul's consolidated leverage ratio for
the 1998 Revolving Credit Loans, or (ii) the Eurodollar Rate, plus a margin of
2.25% for the New Interim Loans, a margin of 2.75% for the Tranche C Loans,
and a margin based on Federal-Mogul's consolidated leverage ratio for the 1998
Revolving Credit Loans. In the case of the 1998 Revolving Credit Loans: (i)
for Base Rate loans, the applicable margin will vary between 0% and 0.5%, and
(ii) for Eurodollar Rate loans, the applicable margin will vary between 0.75%
and 1.5%.
 
 Collateral and Guarantees, Covenants and Events of Default
 
  Indebtedness under the 1998 Credit Agreements is secured by the same
collateral and guaranteed by the same subsidiaries as applicable to the 1997
Credit Agreement. The 1998 Credit Agreements also have the same covenants and
events of default as the 1997 Credit Agreement.
 
 Fees
 
  Federal-Mogul is currently paying a facility fee on the used and unused
portion of each lender's commitment to make 1998 Revolving Credit Loans at the
rate of 0.25% and 0.5% per annum, depending on Federal-Mogul's leverage ratio.
In addition, Federal-Mogul paid customary fees to Chase and reimbursed
customary expenses in connection with the closing of the 1998 Credit
Agreements.
 
REPAYMENTS AND REFINANCING
 
  The 1997 Credit Agreement and the Term Loan Agreement require mandatory
repayments with some or all of the net proceeds received upon the occurrence
of certain events, including issuances by Federal-Mogul of capital stock, the
incurrence by Federal-Mogul of certain debt, certain sales of assets and the
existence of "excess cash flow." The "asset sale" and "excess cash flow" (each
as defined in the 1997 Credit Agreement and the Term Loan Agreement)
prepayment requirements cease to be applicable when certain leverage tests are
met.
 
  Pursuant to these requirements, it is anticipated that the net proceeds from
the Offerings will be used to prepay a portion of the New Interim Loans.
 
  Federal-Mogul has the option to prepay without premium at any time the 1997
Term Loans, the 1998 Term Loans, the 1997 Revolving Credit Loans and the 1998
Revolving Credit Loans.

  FOR PURPOSES OF THIS SECTION OF THE PROSPECTUS SUPPLEMENT ("BUSINESS"),
REFERENCES TO "FEDERAL-MOGUL" OR THE "COMPANY" INCLUDE OPERATIONS ACQUIRED IN
THE ACQUISITIONS OF T&N AND FEL-PRO AND STATISTICS HAVE BEEN PREPARED ON A PRO
FORMA BASIS, GIVING EFFECT TO THE ACQUISITIONS OF T&N AND FEL-PRO AND THE
DISPOSITION OF THE T&N BEARINGS BUSINESS AND THE FEL-PRO CHEMICAL BUSINESS AS

OVERVIEW
 
  Federal-Mogul is a leading global manufacturer and distributor of a broad
range of engine components, other vehicular components and related products.
The Company's products are primarily used in the manufacture and maintenance
of:
 
    . automobiles and light trucks
 
    . heavy duty trucks
 
    . farm and construction vehicles, and
 
    . industrial equipment.
 
  Federal-Mogul's products include:
 
  POWERTRAIN SYSTEM COMPONENTS, which are internal engine components directly
involved in creating a vehicle's movement. These components consist primarily
of engine bearings, bushings, pistons, piston pins, rings, liners and
ignition.
 
  SEALING SYSTEM COMPONENTS, which provide for the encapsulation of fluids and
gases from the engine, transmission and axle and also prevent external objects
from entering the systems. They consist of dynamic seals (which are found
between components that move in relation to one another) and gaskets (which
are located between components that are static in relation to one another).
 
  BRAKES AND FRICTION PRODUCTS, which are used primarily for vehicular brake
systems. The acquisition of Cooper Automotive substantially expanded Federal-
Mogul's existing brakes and friction business and management anticipates
establishing brakes and friction products (previously administered together
with the products listed under "general products", below) as a separate
manufacturing operating unit.
 
  GENERAL PRODUCTS, which consist of Federal-Mogul's remaining product lines,
primarily camshafts, sintered products (which are engine components made from
powdered metal), chassis components and systems protection products (which are
used for shielding against heat, noise, abrasion and stone impingement).
 
  Federal-Mogul markets its products to many of the world's major
manufacturers of new vehicles ("OE manufacturers".) Federal-Mogul also
manufactures and supplies its products and related parts to aftermarket
customers (purchasers of replacement parts) for each category of equipment
described above. Among Federal-Mogul's largest customers are BMW, Caterpillar,
Cummins, DaimlerChrysler, Fiat, Ford, General Motors, LucasVarity, NAPA,
Peugeot, Renault and Volkswagen/Audi (in alphabetical order).
 
  Founded in 1899, Federal-Mogul traditionally focused on the manufacture and
distribution of engine bearings and sealing systems. From 1990 through 1996,
Federal-Mogul pursued a strategy of opening retail auto parts stores in
various domestic and international locations. These geographically-dispersed
stores proved burdensome to manage and resulted in substantial operating
losses. In the fourth quarter of 1996, Federal-Mogul underwent a change of
management, following which the Company initiated a significant restructuring
program

designed to refocus the Company on its core competency of manufacturing. As
part of such restructuring, Federal-Mogul took the following actions: (i)
closed international aftermarket distribution centers in Malaysia and
Singapore; (ii) divested 94 international retail aftermarket operations and
sold or restructured 25 wholesale aftermarket operations; (iii) closed its
Leiters Ford, Indiana, manufacturing facility and consolidated its lighting
products operations in Juarez, Mexico; (iv) consolidated certain of its North
American warehouse facilities; (v) consolidated its customer support functions
previously housed in Phoenix, Arizona, into the Company's Southfield
headquarters; (vi) consolidated its European aftermarket management functions
in Geneva, Switzerland, into the Wiesbaden, Germany, manufacturing
headquarters; and (vii) streamlined certain of its administrative and
operational staff functions worldwide. In addition, by June 30, 1998, the
Company had exited substantially all of its retail businesses. Federal-Mogul
also began to pursue a growth strategy of acquiring complementary
manufacturing companies that enhance the Company's product base, expand its
global manufacturing operations and provide opportunities to capitalize on the
Company's aftermarket distribution network and technological resources.
 
  In connection with its growth strategy, on March 6, 1998 Federal-Mogul
acquired T&N, a U.K.-based supplier of engine and transmission products, for
total consideration of approximately (Pounds)1.46 billion ($2.41 billion,
converted at a blended exchange rate of 1 pound sterling to 1.6510 U.S.
dollars). T&N manufactures and supplies high technology engineered automotive
components and industrial materials including pistons, friction products,
bearings, systems protection, camshafts and sealing products. On February 24,
1998, Federal-Mogul acquired Fel-Pro, a privately-owned automotive parts
manufacturer, for total consideration of approximately $717 million. Fel-Pro
is a premier gasket manufacturer for the North American aftermarket and OE
heavy duty market. See "Recent Acquisitions."
 
  Federal-Mogul currently operates facilities at over 240 locations in 24
countries. On a pro forma basis (giving effect to the acquisitions of T&N and
Fel-Pro and the disposition of the T&N Bearings Business as if they had
occurred on January 1, 1997), Federal-Mogul's total sales for 1997 were $4.8
billion.
 
  Among Federal-Mogul's largest customers are BMW, Caterpillar, Cummins,
DaimlerChrysler, Fiat, Ford, General Motors, LucasVarity, NAPA, Peugeot,
Renault and Volkswagen/Audi (in alphabetical order).
 
BUSINESS STRATEGY
 
  Federal-Mogul's recent restructuring program and the acquisitions which
followed focused the Company on its core competency of manufacturing and
expanded the Company's product base, geographic reach and market penetration.
Key elements of the Company's strategy for continuing this focused growth and
further enhancing its market presence are as follows:
 
 Systems Approach
 
  Due to its broad manufacturing capabilities and product offerings, Federal-
Mogul is one of a small number of manufacturers with the ability to seal
entire engine, transmission and axle systems and to act as a single-source
supplier of engine and sealing components. In addition, Federal-Mogul is
committed to becoming a provider of complete engine modules for its OE
customers. The Company believes that OE manufacturers of automobiles, trucks
and other vehicles are increasingly seeking to reduce the number of suppliers
from which they source parts and to develop relationships with suppliers that
can offer integrated systems and modules in order to lower production costs,
increase quality, provide better technology and shorten product development
cycles. The T&N and Fel-Pro acquisitions, which expanded the Company's gasket,
cast aluminum piston, large bearing and sealing product lines and added
product lines for articulated pistons, cylinder liners and piston rings, are
major steps toward Federal-Mogul's strategic goal of developing global engine
and sealing systems for its OE customers.
 
 Continue Focus on New Product Innovation
 
  The Company's expertise in engineering and research and development has made
Federal-Mogul a leader in virtually all of the products segments in which it
competes. The Company utilizes the latest technologies,
 
                                     S-70
<PAGE>
 
processes and materials to solve problems for customers and to bring new,
innovative products to market. The Company has special competencies in alloy
development, customized materials formulations, surface technology, advanced
modeling and testing and systems engineering. These capabilities allow the
Company to reduce production costs and to develop products that are more
durable and exhibit better interaction with surrounding components. These
innovative products better serve OE customers and aid brand development,
resulting in a higher margin product mix.
 
 Extend Global Manufacturing Reach
 
  The Company is committed to extending its manufacturing capabilities
worldwide in response to the global expansion of its OE manufacturing
customers. The acquisition of T&N and Fel-Pro have substantially increased the
Company's manufacturing presence, particularly in North America and Europe.
Management believes expansion of manufacturing operations to follow the
expansion of OE manufacturers into Latin America, Eastern Europe and Asia
provides significant growth opportunities for the Company in the future.
 
 Pursue Strategic Acquisitions
 
  The vehicular engine and sealing component industry is large and highly
fragmented. The Company believes that as OE manufacturers continue to
outsource and reduce the number of suppliers, opportunities will exist for
further consolidation within the industry. The Company believes that, through
its established presence in these markets and its strong relationships with OE
manufacturers worldwide, the Company is in a favorable position to capitalize
on future industry consolidation. The Company's management has substantial
experience in completing and integrating acquisitions within the automobile
parts industry and believes that this experience will help it select and
pursue acquisition opportunities that can enhance the Company's product base,
expand its global manufacturing operations and further capitalize on the
Company's aftermarket distribution network and technological resources.
 
 Expand Aftermarket Presence
 
  Approximately 48% of the Company's 1997 sales were generated from the
aftermarket. The Company believes that opportunities exist to further leverage
its broad product offerings and to increase its penetration of the worldwide
aftermarket. In addition, the Company believes that its ability to sell
products developed for the OE market to aftermarket customers reduces the
impact of adverse changes in demand for new vehicles.
 
 EVA Focus
 
  In 1997, Federal-Mogul adopted Economic Value Added (EVA(R)) as its primary
system for evaluating financial performance (for purposes including planning,
internal resource allocation and, to an increasing extent, determination of
incentive compensation). EVA is based upon comparison of the cost of capital
with the return on such capital. EVA is equal to net operating profits after
economic taxes less a charge for capital invested in the Company. This charge
for capital is equal to the product of the total capital invested in the
Company and the targeted weighted average cost of capital. In connection with
this effort, the Company's management has placed significant emphasis on
improving the Company's financial performance and achieving various operating
efficiencies through technical development, manufacturing, marketing and
administrative rationalization. The Company's EVA improved significantly in
1997 due primarily to improved operating margins (which margins rose from 4.9%
in 1996 to 7.7% in 1997) combined with $166 million of cash flow from
continuing operations (net of expenditures for property, plant and equipment)
in 1997. EVA is also being applied to the integration of T&N and Fel-Pro to
optimize synergies and cost savings. As the Company continues to expand both
its product base and its geographic scope, management will evaluate
investments and acquisitions based on both EVA and strategic importance. In
addition, the Company currently determines compensation for certain top
managers using an EVA based system and expects to increase the number of
managers participating in its EVA based compensation system to over 200 in
1999.

REORGANIZATION
 
  Following the acquisitions of T&N and Fel-Pro, Federal-Mogul's integrated
operations are being reorganized to realize synergies and effectively
coordinate operations. Operations will be conducted through three
manufacturing operating units corresponding to major product areas: Powertrain
Systems, Sealing Systems and General Products. The major product categories in
Powertrain Systems include engine bearings and piston products. Sealing
Systems includes dynamic seals and gaskets. General Products include
camshafts, friction products, sintered products, systems protection products
and a number of smaller product lines. The Worldwide Aftermarket organization
is responsible for Federal-Mogul's global aftermarket sales, marketing and
distribution.
 
  The components of Federal-Mogul's plan for integrating operations acquired
with T&N and Fel-Pro include: closure of several manufacturing facilities
worldwide; relocation of highly manual manufacturing product lines to lower
cost regions or more suitable locations; consolidation of overlapping
manufacturing, technical and sales facilities and joint ventures; closure of
selected aftermarket central warehouses and selected in-country warehouses;
consolidation of aftermarket marketing and customer support functions; and
streamlining of administrative, sales, marketing and product engineering
staffs worldwide. An anticipated result of the integration plan and the
restructuring is a reduction of approximately 4,200 employees.
 
  In connection with securing regulatory approvals for the acquisition of T&N,
Federal-Mogul executed an Agreement Containing Consent Order with the FTC on
February 27, 1998. Pursuant to this agreement Federal-Mogul must divest the
T&N Bearings Business within six months after the FTC declares the consent
order final and must provide for independent management of those assets
pending such divestiture. The agreement stipulates that the T&N Bearings
Business is to be maintained as a viable, independent competitor of Federal-
Mogul and that Federal-Mogul shall not attempt to direct the activities of, or
exercise control over, the T&N Bearings Business or have contact with the T&N
Bearings Business outside of normal business activities. The T&N Bearings
Business accounted for approximately $393.1 million of T&N's 1997 revenues and
employed approximately 4,000 people. Certain pro forma information related to
the disposition of the T&N Bearings Business is set forth under the caption
"Unaudited Pro Forma Financial Data: T&N, Fel-Pro and Cooper Automotive." In
addition, T&N's North American aftermarket business is being held separately
(on an interim basis) as an independent business pursuant to the Agreement
Containing Consent Order.
 
  On October 27, 1998, Federal-Mogul entered into an agreement to sell the T&N
Bearings Business and certain other engine hard part assets to Dana
Corporation for a purchase price of $430 million. Completion of the sale is
subject to regulation approval and is expected to occur by the end of 1998.

(1) Excluding approximately $600 million of sourced aftermarket product.
 
POWERTRAIN SYSTEMS
 
  Federal-Mogul's Powertrain Systems products are used in automotive, light
truck, heavy duty, industrial, marine, agricultural, power generation and
small air-cooled engine applications. The Powertrain Systems (not including
the T&N Bearings Business to be divested) accounted for $1.9 billion of
Federal-Mogul's 1997 consolidated sales, of which 41% were in North America,
52% were in Europe and 7% were in the rest of the world. In 1997, Powertrain
Systems unit's five largest customers by sales volume were Caterpillar,
Cummins, Ford, General Motors and Volkswagen/Audi (in alphabetical order).
Approximately 68% of the sales in 1997 for Powertrain Systems were to OE
customers while 32% were to aftermarket customers.
 
  Federal-Mogul's Powertrain Systems operations combine large bearings and
piston products operations acquired in the T&N acquisition with pre-existing
powertrain assets of Federal-Mogul, primarily bearings operations. The
addition of T&N greatly expanded Federal-Mogul's presence in cast aluminum
pistons and large bearings as well as adding four additional product lines,
articulated pistons, piston rings, cylinder liners and piston pins. The
Company's Powertrain Systems maintains 57 manufacturing locations in 16
countries. (T&N's other Powertrain Systems operations--thinwall bearings and
dry bearings--are to be divested for regulatory reasons and are held
separately, in the interim, see "--Reorganization.")
 
  Engine Bearings, Bushings, Washers and Large Bearings. Engine bearings,
bushings, washers and large bearings accounted for approximately 40% of the
sales for Powertrain Systems. Federal-Mogul manufactures thin wall engine
bearings, bushings and washers for original equipment and aftermarket sales.
These products include
 
                                     S-73
<PAGE>
 
bimetallic and trimetallic journal bearings (main, connecting rod, thrust and
tilting pad), bimetallic and trimetallic bushings and washers, valve plates,
labyrinth seals, dry bearings and sputter bearings. Federal-Mogul's large
bearings products--heavy wall bearings, rotating plant bearings and structural
products--are sold only to OE customers. Engine bearings, bushings, washers
and large bearings are sold under the brand names Federal-Mogul(R) and
Glyco.(R)
 
  Pistons and Piston Pins. Pistons and piston pins accounted for approximately
33% of the sales for Powertrain Systems. Federal-Mogul designs and
manufactures cast aluminum pistons for all gasoline and diesel engine
applications, articulated aluminum body/steel crown pistons for heavy duty
diesel applications, piston rings for all classes of internal combustion
engines, cylinder liners in cast iron for new generation aluminum block
engines and piston pins from steel. The addition of T&N has significantly
expanded the technology, scope and range of pistons offered by Federal-Mogul,
most notably in the OE market. The T&N acquisition has also added piston rings
and a wide range of high strength steel piston pins (also known as wrist pins
or gudgeon pins) to the Federal-Mogul product line. Pistons and piston rings
are sold under the brand names AE Goetze(R) and Sterling.(R)
 
  Rings and Liners. Rings and liners accounted for approximately 27% of the
sales for Powertrain Systems. Federal-Mogul manufactures a wide range of cast
iron or steel rings, plasma, chrome and CKS coatings and wet, dry and cast
liners. Federal-Mogul now designs and manufactures a wide range of cast iron
and steel piston rings. With the addition of T&N and Fel-Pro, Federal-Mogul
added cylinder liners to its product line. Rings and liners are marketed under
the brand name AE Goetze.(R)
 
SEALING SYSTEMS
 
  Federal-Mogul's Sealing Systems products are used in automotive, light
truck, heavy duty diesel, agricultural, off-highway, marine, railroad, high
performance and industrial applications. Sealing Systems accounted for $1.1
billion of Federal-Mogul's 1997 consolidated sales, of which 66% were in North
America, 23% were in Europe and 11% were in the rest of the world. In 1997,
this division's five largest customers by sales volume were Chrysler, Cummins,
Fiat, Ford and General Motors (in alphabetical order). Approximately 47% of
the sales in 1997 for Sealing Systems division were to OE customers while 53%
were to aftermarket customers.
 
  Federal-Mogul's Sealing Systems operations combine the gaskets operations
acquired in the T&N and Fel-Pro acquisitions with the pre-existing Federal-
Mogul dynamic seals business. The acquisitions of T&N and Fel-Pro have made
Federal-Mogul one of a select number of manufacturers with the ability to seal
entire engines, transmissions and axle systems. The Company's Sealing Systems
maintains 23 manufacturing locations in 12 countries.
 
  Dynamic Seals. Dynamic seals accounted for approximately 30% of the sales
for Sealing Systems division. Federal-Mogul manufactures a line of dynamic
seals consisting of oil seals (for engines, transmissions and axles),
crankshaft seal carrier assemblies, valve stem seals, air conditioning
compressor seals, bonded pistons for transmissions, 24-hour made-to-order oil
seals, wear sleeves for shaft sealing surface repair and truck hub seals.
These products are marketed under the brand names National(R), Mather(R),
STS(R), Redi-Seal(R), Redi-Sleeve(R) and Unipiston(R).
 
  Gaskets. Gaskets accounted for approximately 70% of the sales for Sealing
Systems. Federal-Mogul utilizes a wide range of material technologies to
manufacture a full range of gasket types, including cylinder head gaskets in
multi-layer steel, graphite, edge molded metal plate and other composites,
valve and rocker cover gaskets, intake and exhaust manifold gaskets and
miscellaneous gaskets in steel, composite, elastomeric and spiral wound.
Federal-Mogul also offers a complete line of repair kits for professional
installers under the brand name of Fel-Pro.(R) Federal-Mogul established a
strong presence in the heavy duty OE market for gaskets (including, primarily,
gaskets for light and heavy duty diesel engines) through its acquisition of
Fel-Pro. While Fel-Pro's market share of automotive OE gaskets was more
limited, T&N's Sealing Products division has a stronger presence in the
automotive OE market, adding balance to Federal-Mogul's overall OE gasket
activities.

GENERAL PRODUCTS
 
  Federal-Mogul's General Products includes four primary product lines, which
were primarily acquired with T&N: camshafts, friction products, sintered
products and systems protection products. In addition, General Products
includes a number of smaller product lines, some of which (fuel systems
components and lighting products) pre-date the acquisition of T&N and others
of which (heat transfer products and textiles) were acquired with T&N.
Products Federal-Mogul sources from other manufacturers, which are not related
to Powertrain Systems and Sealing Systems, are included in General Products
and distributed by Worldwide Aftermarket.
 
  Products manufactured by Federal-Mogul's General Products accounted for $1.2
billion of Federal-Mogul's 1997 consolidated sales (excluding $600 million of
sourced aftermarket product). Approximately 34% of the unit's manufactured
sales were in North America, 57% were in Europe and 9% were in the rest of the
world. In 1997, General Products' five largest customers by sales volume were
Ford, General Motors, LucasVarity, Peugeot and Renault (in alphabetical
order). Approximately 64% of the sales in 1997 for General Products of
products it manufactures were to OE customers while 36% were to aftermarket
customers. The Company's General Products maintains 53 manufacturing locations
in 17 countries.
 
  Camshafts. Camshafts accounted for approximately 13% of Federal-Mogul
manufactured products sales for General Products. Federal-Mogul casts,
machines and assembles camshafts primarily for the automotive market. These
products are marketed under the brand names Weyburn-Bartel(R) and Weyburn-
Lydmet(R).
 
  Friction Products. Friction products accounted for approximately 42% of
Federal-Mogul manufactured products sales for General Products. Federal-Mogul
manufactures disc brake pads, drum brakes and brake linings for the automotive
and commercial vehicle sector. These products are marketed under the brand
name Ferodo(R) and are sold primarily in Europe.
 
  Sintered Products. Sintered products accounted for approximately 17% of
Federal-Mogul manufactured products sales for General Products. Federal-Mogul
utilizes advanced powder metallurgy techniques for the manufacture of a wide
range of automotive components including valve guides, valve seat inserts, ABS
sensor rings and other transmission components, together with engine
components, principally pulleys, gears and sprockets. These products are
marketed under the brand names Brico(R) and Sintertech(R), solely to OE
customers.
 
  Systems Protection Products. Systems protection products accounted for
approximately 9% of Federal-Mogul manufactured products sales for General
Products. Federal-Mogul manufactures a wide variety of products used for
automotive under body and under hood protection from heat, noise, abrasion and
stone impingement. Most of these products are based on braided, knitted and
non-woven fabrics. Products based on the same technologies are sold in the
electrical, white goods and aerospace industries. These products are marketed
under the brand name Bentley-Harris(R), solely to OE customers, and are sold
primarily in North America.
 
  Other General Products. Other general products--primarily consisting of heat
transfer products, fuel system components and lighting products--accounted for
approximately 19% of Federal-Mogul manufactured products sales for General
Products. Federal-Mogul is in the process of reselling the chemical
manufacturing operations acquired with Fel-Pro (representing approximately
$32.8 million of Fel-Pro's 1997 net sales and $2.6 million of Fel-Pro's 1997
net income). The primary components of other general products are:
 
  . heat transfer products (engine cooling radiators in both aluminum and
    copper brass construction and heater, ventilator and air conditioning
    units for automotive in-cab use) manufactured in South Africa for sale in
    the South African market and for global export under the brand names
    Silverton(R), FHE(R) and Connoisseur Auto Air Conditioning(R);
 
  . fuel system components (a full line of fuel pumps including mechanical
    fuel pumps, diesel lift pumps, electric fuel pumps, electric fuel modules
    and hanger assemblies) marketed in North America, under the brand name
    Carter(R); and
 
                                     S-75
<PAGE>
 
  . lighting products (clearance marker lamps, front, side and rear signal
    lamps, stop, tail and turn lights, emergency lighting, turn signal
    switches, auxiliary lighting and back-up lamps) marketed under the brand
    name Signal-Stat(R).
 
WORLDWIDE AFTERMARKET
 
  Federal-Mogul's North American distribution centers in Jacksonville,
Alabama, LaGrange, Indiana, and Maysville, Kentucky (the "Distribution
Centers"), served as the core of Federal-Mogul's domestic aftermarket
distribution network prior to the acquisitions of T&N and Fel-Pro. Products
are shipped from these Distribution Centers to service centers in the United
States and Canada. For Latin American sales, products are shipped through a
facility in Weston, Florida to two international regional distribution centers
and 15 Latin American branches. For European sales, products are shipped
through Federal-Mogul's facility in Kontich, Belgium.
 
  T&N and Fel-Pro each brought with them developed aftermarket operations
duplicating, in part, Federal-Mogul's existing capabilities. T&N was, at the
time of its acquisition, the world's largest supplier of engine parts to the
independent aftermarket, as measured by revenues (with approximately 80% of
the parts distributed having been produced by T&N). Fel-Pro also brought
significant aftermarket penetration with it, built on the substantial brand
loyalty its gasket lines have acquired through a history of technological
innovations, merchandising and marketing, which have differentiated them in
the market, particularly among professional installers. Management thus
believes that aftermarket distribution provides significant opportunities for
realization of synergies.
 
  T&N's aftermarket distribution system at the time of the acquisition
included 36 major distribution centers and sales offices utilizing over 1,600
employees worldwide to distribute over 200,000 component parts of 5,000 engine
models via its AE and Goetze marketing networks. The Company's Worldwide
Aftermarket includes 118 distribution facilities in 19 countries.
 
  Fel-Pro's domestic aftermarket business, focused primarily on gaskets,
primarily distributed from a state-of-the-art facility inside its Skokie,
Illinois plant, using a highly automated, virtually paperless process.
 
CUSTOMERS
 
  Among Federal-Mogul's largest customers are BMW, Caterpillar, Cummins,
DaimlerChrysler, Fiat, Ford, General Motors, LucasVarity, NAPA, Peugeot,
Renault and Volkswagen/Audi (in alphabetical order).
 
  Original Equipment. Federal-Mogul's OE customers consist primarily of
automotive and heavy duty vehicle customers, as well as farm and industrial
equipment manufacturers, agricultural, off-highway, marine, railroad, high
performance and industrial applications. Federal-Mogul has well-established
relationships with substantially all major North American and European
automotive OE manufacturers, some pre-existing and others resulting from the
acquisitions of T&N and Fel-Pro. Management believes there are additional
system opportunities with OE manufacturers in the Asia-Pacific and Latin
American regions. In addition, management believes that the acquisitions of
T&N and Fel-Pro have positioned Federal-Mogul to take advantage of developing
OE customer demand for single supplier systems and modules in the future,
particularly in light of Federal-Mogul's global reach and capabilities. See
"--Business Strategy."
 
  Aftermarket. Federal-Mogul's domestic and international customers include
independent warehouse distributors who redistribute products to local parts
suppliers called "jobbers," industrial bearing distributors, distributors of
heavy duty vehicular parts, engine rebuilders and retail parts stores. The
breadth of Federal-Mogul's product lines, together with the strength of its
brand names and sales force, are central to Federal-Mogul's aftermarket
operations.
 
RESEARCH AND DEVELOPMENT
 
  Federal-Mogul maintains technical centers in Europe and North America to
develop and provide advanced materials, products and manufacturing processes
for all of its manufacturing units, including facilities acquired
 
                                     S-76
<PAGE>
 
with T&N and Fel-Pro. Federal-Mogul's expertise in engineering, research and
development ensures that the latest technologies, processes and materials are
considered in solving problems for customers and bringing new, innovative
product to market. Federal-Mogul provides its customers with real-time
engineering capabilities and design development in their home countries. In
recognition of the importance of technology throughout its operations,
following the acquisitions, Federal-Mogul created the post of Vice President--
Technology to coordinate technological activities throughout its operations.
 
  The acquisitions of T&N and Fel-Pro provided Federal-Mogul with substantial
additional technological expertise. In particular, the newly acquired
technical centers in the United Kingdom and the United States bring a new
depth of capability in materials development, surface engineering,
computational analysis, engine testing and systems engineering. Recent
achievements of these centers include development of advanced piston alloys,
novel bearing coatings, brake pads for motor sport applications, engine
structure modelling to predict gasket performance and test techniques for
measurement of bore distortion in running engines.
 
  The Fel-Pro acquisition brought substantial research operations focusing on
gaskets and their manufacture, including complete material, application design
and process development capabilities and a dedicated design/engineering staff
of over 100 employees. Recent technology innovations pioneered by Fel-Pro
include PermaDry Plus(R), multi-layered steel head gaskets, noise and
vibration dampening devices and rubber edge molded gaskets. In the past, Fel-
Pro has introduced several product innovations including Fel-Coprene(R),
Print-O-Seal(R) and Perma-Torque Blue(R), which have become market standards
in the gasket aftermarket.
 
  Technological activities are conducted at facilities Federal-Mogul acquired
from T&N including, in particular, its central technical center at Cawston,
England, its facility at Burscheid, Germany, and its technical center at
Plymouth, Michigan, and at Fel-Pro's facilities in Skokie, Illinois, as well
as at Federal-Mogul's major pre-existing technological centers, in Ann Arbor,
Michigan, Logansport, Indiana, Malden, Missouri, and Wiesbaden, Germany. Each
of Federal-Mogul's operating units is engaged in various engineering, research
and development efforts working side by side with customers to develop custom
solutions unique to their needs.
 
  Total expenditures for research and development activities were
approximately $102.8 million in 1997, $101.6 million in 1996 and $99.8 million
in 1995.
 
SUPPLIERS
 
  Federal-Mogul sells its manufactured parts as well as parts manufactured by
other manufacturers to the aftermarket. In 1997, only one outside supplier of
Federal-Mogul provided products that accounted for more than 5% of Federal-
Mogul's net sales. This supplier provided products accounting for
significantly less than 10% of Federal-Mogul's net sales, pursuant to a long-
term contract.
 
  Federal-Mogul does not normally experience supply shortages of raw
materials. Certain of Federal-Mogul's relationships with its long-term
suppliers are contractual.
 
  In connection with the acquisition of the automotive aftermarket business of
TRW, Inc. ("TRW") in 1992, Federal-Mogul and TRW entered into a Supply
Agreement for an initial term of 15 years (the "Supply Period"), pursuant to
which TRW agreed to supply Federal-Mogul with parts manufactured by TRW and
distributed by Federal-Mogul. Upon completion of the Cooper Acquisition,
Federal-Mogul's distributorship relationship with TRW will become non-
exclusive, except in Europe where Federal-Mogul will remain TRW's exclusive
distributor. After the Supply Period, the Supply Agreement will be
automatically renewed for one year periods unless terminated by either party.
 
LEGAL PROCEEDINGS
 
 T&N Asbestos
 
  In the United States, Federal-Mogul's subsidiary, T&N plc, and two of T&N
plc's U.S. subsidiaries (the "T&N Companies") are among many defendants named
in numerous court actions alleging personal injury
 
                                     S-77
<PAGE>
 
resulting from exposure to asbestos or asbestos-containing products. T&N plc
is also subject to asbestos-disease litigation, to a lesser extent, in the UK
and to property damage litigation based upon asbestos in the United States.
Because of the slow onset of asbestos-related diseases, management anticipates
that similar claims will be made in the future. Although T&N has carefully
projected its future asbestos liability, the assumptions underlying such
projections continuously change and it is therefore not possible to project
with any certainty the number of such claims that may be made nor the
expenditure which may arise therefrom. T&N has appointed the Center for Claims
Resolution ("CCR"), a not-for-profit coalition of former asbestos producers
and sellers, as its representative in relation to all asbestos-related
personal injury claims made against the T&N Companies in the United States.
 
  Prior to its acquisition by Federal-Mogul, T&N secured, by payment of a
premium of (Pounds)92 million, a (Pounds)500 million layer of insurance cover
which will be triggered should the aggregate number of claims notified after
June 30, 1996, where the exposure occurred prior to that date ("IBNR claims"),
exceed (Pounds)690 million. In connection with the T&N acquisition, Federal-
Mogul recorded reserves for IBNR claims up to the self-retention amount of
T&N's IBNR insurance policies. In addition, the Company has provided reserves
for claims notified prior to June 30, 1996 claims. As of September 30, 1998,
the Company has provided $1.292 billion as its estimate for future costs
related to resolving asbestos claims. For discussion of asbestos-related
liabilities and reserves, see Notes 19 and 28 to the T&N Financial Statements
(found in the Company's Form 8-K filed on April 7, 1998,) and "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
T&N--Asbestos."
 
  While management believes that estimated reserves are appropriate for
anticipated losses arising from T&N's asbestos-related claims, no assurance
can be given that T&N will not be subject to material additional liabilities
and significant additional litigation relating to asbestos. Any such
liabilities or litigation could have a material adverse effect on Federal-
Mogul's results of operations, business, liquidity and financial condition.
See "Risk Factors--T&N's Asbestos Liability."
 
 Federal-Mogul and Fel-Pro Asbestos
 
  Federal-Mogul also is one of a large number of defendants in a number of
lawsuits brought by claimants alleging injury due to exposure to asbestos. In
addition, Fel-Pro has been named as a defendant in a large number of product
liability cases involving asbestos, primarily involving gasket or packing
products sold to shipowners. Federal-Mogul is defending all such claims
vigorously and believes that it and Fel-Pro have substantial defenses to
liability and adequate insurance coverage for defense costs (though Fel-Pro
has agreed with its insurers to pay approximately 20% of defense costs, in
exchange for the right to a significant role in decisions regarding the
litigation). While the outcome of litigation cannot be predicted with
certainty, after consulting with the office of Federal-Mogul's general
counsel, management believes that asbestos claims pending against Federal-
Mogul and Fel-Pro as of September 30, 1998 will not have a material effect on
Federal-Mogul's financial position.
 
 Other
 
  Federal-Mogul is involved in various other legal actions and claims,
directly and through its subsidiaries (including T&N and Fel-Pro). After
taking into consideration legal counsel's evaluation of such actions,
management is of the opinion that their outcomes are not reasonably likely to
have a material adverse effect on Federal-Mogul's financial position operating
results or cash flow.
 
  For information respecting lawsuits concerning environmental matters to
which Federal-Mogul is a party, see "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Federal-Mogul--Environmental
Matters."
 
EMPLOYEE RELATIONS
 
  On September 30, 1998, Federal-Mogul had approximately 41,500 full-time
employees (including the T&N Bearings Business), of whom approximately 15,600
were employed in the United States. Approximately 13,300 of these employees
work for operations predating the acquisitions of T&N and Fel-Pro,
approximately 25,400 work for operations acquired with T&N and approximately
2,800 work for operations acquired with Fel-Pro. An anticipated result of the
integration plan and restructuring relating to the acquisitions of T&N and
Fel-Pro is a reduction of approximately 4,200 employees.
 
                                     S-78
<PAGE>
 
  Approximately 40% of Federal-Mogul's United States employees are represented
by six unions. Approximately 55% of Federal-Mogul's foreign employees are
represented by various unions. Each of Federal-Mogul's unionized manufacturing
facilities has its own contract with its own expiration date and, as a result,
no contract expiration date affects more than one facility. Federal-Mogul
believes its labor relations to be good.
 
ENVIRONMENTAL REGULATIONS
 
  Federal-Mogul's operations, in common with those of industry generally, are
subject to numerous existing and proposed laws and governmental regulations
designed to protect the environment, particularly regarding plant wastes and
emissions and solid waste disposal. Capital expenditures for property, plant
and equipment for environment control activities did not have a material
impact on Federal-Mogul's financial position or results of operations in 1997
and are not expected to have a material impact on Federal-Mogul's financial
position or results of operations in 1998 or 1999.
 
BACKLOG
 
  The majority of Federal-Mogul's products are not on a backlog status. They
are produced from readily available materials and have a relatively short
manufacturing cycle. For products supplied by outside suppliers, Federal-Mogul
generally purchases products from more than one source. Federal-Mogul expects
to be capable of handling the anticipated 1998 sales volumes.
 
PATENTS AND LICENSES
 
  Federal-Mogul is committed to protecting its technology investments and
market share through an active and growing international patent portfolio.
Federal-Mogul's patent portfolio is composed of a large number of foreign and
U.S. patents and pending patent applications which relate to a wide variety of
products and processes. In the aggregate, Federal-Mogul's international patent
portfolio is of material importance to its business; however, Federal-Mogul
does not consider any international patent or group of international patents
relating to a particular product or process to be of material importance when
judged from the standpoint of the business as a whole.
 
COMPETITION
 
  The global vehicular parts business is highly competitive. Federal-Mogul
competes with many of its customers that produce their own components as well
as with independent manufacturers and distributors of component parts in the
United States and abroad. In general, competition for such sales is based on
price, product quality, customer service and the breadth of products offered
by a given supplier. Federal-Mogul has attempted to meet these competitive
challenges through more efficiently integrating its manufacturing and
distribution operations, expanding its product coverage within its core
businesses, and expanding its worldwide distribution network.
 
PROPERTIES
 
  Federal-Mogul conducts its business from its World Headquarters complex in
Southfield, Michigan, which is leased pursuant to a sale/leaseback
arrangement. At September 30, 1998, Federal-Mogul had over 120 manufacturing
facilities with in excess of 16 million square feet (approximately 80% of
which were owned and 20% were leased) and over 100 aftermarket facilities with
in excess of 3.5 million square feet (approximately 10% of which were owned
and 90% were leased). Over half of the manufacturing facilities (by square
footage) were in Europe and approximately one-third were in North America.
Over 85% of aftermarket facilities (by square footage) were in North America,
with a strong majority of the remainder in Europe. Federal-Mogul also had
other facilities (primarily research and office only sites) accounting for
approximately 800,000 square feet.
 
  All owned and leased properties are well maintained and equipped for the
purposes for which they are used. Federal-Mogul believes that its facilities
are suitable and adequate for the operations involved. In the case of leased
properties, Federal-Mogul believes that the leases could be renewed or
comparable facilities could be obtained without materially affecting
operations.

                         DESCRIPTION OF CAPITAL STOCK
 
  The following statements are summaries of certain provisions of Federal-
Mogul's Restated Articles of Incorporation (the "Articles of Incorporation")
and Bylaws and of the Rights Agreement, dated as of November 3, 1988, as
amended, between Federal-Mogul and The Bank of New York, as Rights Agent (the
"Rights Agreement"). Such summaries do not purport to be complete and are
subject to, and are qualified in their entirety by reference to, all of the
provisions of the Restated Articles of Incorporation, the Bylaws and the
Rights Agreement, including definitions therein of certain terms.
 
AUTHORIZED CAPITAL STOCK
 
  Federal-Mogul's authorized capital stock consists of 5,000,000 shares of
preferred stock, which is issuable in series, and 260,000,000 shares of Common
Stock. At November 11, 1998, Federal-Mogul had outstanding 739,279 shares of
Series C ESOP Convertible Preferred Stock, 607,744.2 shares of Series E
Mandatorily Convertible Preferred Stock and 53,323,874 shares of Common Stock.
At November 11, 1998, of 1,500,000 shares of Common Stock authorized in 1984
under Federal-Mogul's incentive stock plans, no shares remained issuable; of
2,300,000 shares authorized in 1989, an aggregate of 371,942 shares remained
issuable; and of 1,300,000 shares authorized in 1997 and 2,900,000 shares
authorized in 1998, an aggregate of 3,338,695 shares remained issuable. See
"--Incentive Stock Plans."
 
COMMON STOCK
 
  The holders of Common Stock are entitled to receive such dividends as may be
declared from time to time by the Board of Directors out of funds legally
available therefor. The holders of Common Stock are entitled to one vote per
share on all matters submitted to a vote of shareholders and do not have
cumulative voting rights. Holders of Common Stock are entitled to receive,
upon any liquidation of Federal-Mogul, all remaining assets available for
distribution to shareholders after satisfaction of Federal-Mogul's liabilities
and the preferential rights of any preferred stock that may then be issued and
outstanding. The outstanding shares of Common Stock are, and the Shares
offered hereby will be, fully paid and nonassessable. The Common Stock is
listed on the NYSE. The holders of Common Stock have no preemptive, conversion
or redemption rights. The registrar and transfer agent for the Common Stock is
The Bank of New York.
 
PREFERRED SHARE PURCHASE RIGHTS
 
  In 1988, Federal-Mogul's Board of Directors authorized the distribution of
one Preferred Share Purchase Right (a "Right") for each outstanding share of
Common Stock. Each Right entitles the holder thereof to buy one-half of one
one-hundredth of a share of Series B Junior Participating Preferred Stock at a
price of $70.00. The Rights are governed by the Rights Agreement.
 
  As distributed, the Rights trade together with the Common Stock. They may be
exercised or traded separately only after the earlier to occur of: (i) 10 days
following a public announcement that a person or group of persons has obtained
the right to acquire 10% or more of the outstanding Common Stock (20% in the
case of certain institutional investors), or (ii) 10 business days (or such
later date as may be determined by action of the Board of Directors) following
the commencement or announcement of an intent to make a tender offer or
exchange offer which would result in beneficial ownership by a person or group
of persons of 10% or more of the outstanding Common Stock.
 
  If the acquiring person or group of persons acquires 10% or more of the
Common Stock, each Right (other than those held by the acquirer) will entitle
its holder to purchase, at the Right's exercise price, shares of Common Stock
having a market value of twice the Right's exercise price. Additionally, if
Federal-Mogul is acquired in a merger or other business combination, each
Right (other than those held by the surviving or acquiring company) will
entitle its holder to purchase, at the Right's exercise price, shares of the
acquiring company's stock (or Common Stock of Federal-Mogul if it is the
surviving corporation) having a market value of twice the Right's exercise
price.
 
                                     S-85
<PAGE>
 
  Rights may be redeemed at the option of the Board of Directors for $0.005
per Right at any time before a person or group or persons acquires 10% or more
of Federal-Mogul's Common Stock. The Board may amend the Rights at any time
without shareholder approval. The Rights will expire by their terms on April
30, 1999.
 
  The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group that attempts to acquire Federal-
Mogul in a manner that causes the Rights to become exercisable. Federal-Mogul
believes, however, that the Rights would neither affect any prospective
offeror willing to negotiate with the Board of Directors of Federal-Mogul nor
interfere with any merger or other business combination approved by the Board
of Directors.
 
SERIES C ESOP CONVERTIBLE PREFERRED STOCK
 
  In February 1989, Federal-Mogul established an Employee Stock Ownership Plan
(the "ESOP") and issued 1,000,000 shares of Series C ESOP Convertible
Preferred Stock ("Series C Stock") to the ESOP, of which 762,939 shares were
outstanding at March 31, 1998. Such shares bear a dividend of $4.78125 per
share per annum, subject to certain adjustments. The shares of Series C ESOP
Convertible Preferred Stock are convertible into shares of Common Stock at a
rate of two shares of Common Stock per share, subject to adjustment. The
Series C Stock may be issued only to a trustee acting on behalf of an employee
stock ownership plan or other employee benefit plan of Federal-Mogul and will
be automatically converted into shares of Common Stock in the event of any
transfer to a person other than such trustee. Such Series C Stock shares
provide for a liquidation preference of $63.75 per share plus accrued and
unpaid dividends. The Series C Stock is redeemable, in whole or in part, at
the option of Federal-Mogul at a redemption price per share currently equal to
100.75% of the liquidation preference, declining to 100% of the liquidation
preference on and after January 1, 1999, plus, in each case, accrued and
unpaid dividends. Holders of the Series C Stock have full voting rights and
generally vote together with the Common Stock as one class. Each share of the
Series C Stock has such number of votes as equals the number of shares of
Common Stock into which such share could be converted on the record date for
determining the shareholders entitled to vote, or currently two votes per
share. The shares of the Series C Stock are entitled to vote separately on
certain matters. The shares of the Series C Stock are not subject to any
sinking fund provisions and have no preemptive rights. The shares of the
Series C Stock rank senior to Common Stock as to the payment of dividends and
distribution of assets on liquidation, dissolution and winding up of Federal-
Mogul.
 
  In the event that Federal-Mogul is unable to pay dividends on the Series C
Stock, Federal-Mogul is required, pursuant to the terms of the ESOP, to make a
contribution to the ESOP to satisfy the then current debt service requirements
of the ESOP Note (which obligation is fully reflected in long-term debt on
Federal-Mogul's balance sheet). See "Capitalization."
 
SERIES E MANDATORY EXCHANGEABLE PREFERRED STOCK
 
  On February 24, 1998, Federal-Mogul issued 1,030,325.6 shares of Series E
Stock to holders of equity interests in the Fel-Pro entities as partial
compensation for the acquisition thereof. 422,581.4 shares of Series E Stock
were converted into 2,112,907 shares of Common Stock for inclusion in the June
Equity Offering, resulting in a reduction in the number of shares of Series E
Stock outstanding to 607,744.2 shares.
 
  The shares of Series E Stock are mandatorily exchangeable into shares of
Common Stock at a rate of five shares of Common Stock for each share of Series
E Stock (currently representing an aggregate of 3,038,701 shares of Common
Stock), subject to adjustment, upon the earlier of: (i) the fifteenth day
after holders of two-thirds of the outstanding Series E Stock have requested
such exchange, (ii) the effective date of a registration statement filed at
the request of holders of a majority of the Series E Stock pursuant to the
registration rights agreement Federal-Mogul executed for the benefit of
holders of Series E Stock and (iii) February 24, 1999.
 
                                     S-86
<PAGE>
 
  Shares of Series E Stock bear a fully cumulative dividend of $2.40 per share
per annum, payable quarterly in arrears, subject to increase to $14.35 per
share per annum if shares of Series E Stock remain outstanding after February
24, 1999, increasing by $2.05 each month thereafter to $26.65 per share per
annum as of August 24, 1999, subject to certain adjustments. Holders of the
Series E Stock have no voting rights through February 24, 1999, after which
they have full voting rights and generally vote together with the Common Stock
as one class, each share of the Series E Stock having such number of votes as
equals the number of shares of Common Stock into which such share could be
converted on the record date for determining the shareholders entitled to
vote, currently five votes per share. The shares of the Series E Stock are not
subject to any sinking fund or redemptive provisions and have no preemptive
rights. The shares of the Series E Stock rank senior to Common Stock as to the
payment of dividends and in parity to Common Stock as to distribution of
assets on liquidation, dissolution and winding up of Federal-Mogul.
 
  The holders of a majority of the Common Shares into which the Series E Stock
is convertible or has been converted may, upon no more than three occasions,
request registration of all or part of such shares of Common Stock at any time
after January 1, 1999. Such rights terminate at any point at which there are
fewer than 3,000,000 shares of Common Stock eligible for such registration and
such shares may be sold without restriction pursuant to Rule 144(k) under the
Securities Act of 1933. The holders initiating the demand registration may
elect whether the offering of the relevant shares upon registration shall be
in the form of a firm commitment underwritten offering or otherwise (subject
to certain restrictions, such as a determination by the underwriter of an
offering that inclusion of the requested shares would adversely affect the
marketability of the Common Stock).
 
CERTAIN PROVISIONS
 
  The Articles of Incorporation and Bylaws of Federal-Mogul and the Rights
Agreement contain provisions, summarized below, that could have the effect of
delaying, deterring or preventing a change of control of Federal-Mogul. This
summary does not purport to be complete and is subject to, and qualified in
its entirety by, the provisions of the Restated Articles of Incorporation and
Bylaws and the Rights Agreement.
 
FEDERAL-MOGUL'S ARTICLES OF INCORPORATION
 
  Federal-Mogul's Articles of Incorporation provide that the approval of a
business combination (as hereinafter defined) requires (in addition to any
other vote that may be required) the affirmative vote of at least a majority
of the outstanding shares of preferred stock entitled to vote thereon and
Common Stock, voting as a single class. In addition, (a) where the Articles of
Incorporation require the approval of the holder of the preferred stock or one
or more series thereof considered as a separate class, such business
combination shall also require the affirmative vote of at least a majority of
the outstanding shares of the preferred stock or such series thereof
considered as a separate class that are not owned by an Interested Shareholder
(as hereinafter defined) and (b) where applicable law requires that a
transaction be approved by any class or series of Federal-Mogul's stock or any
combination thereof considered as a single class, such transaction shall also
require the affirmative vote of at least a majority of the shares of each such
class or series or combination considered as a single class that are not owned
by the Interested Shareholder.
 
  The voting requirements set forth in the previous paragraph shall not apply
to any business combination if (a) Federal-Mogul's Board of Directors includes
at least one member who was a duly elected and acting member of the Board of
Directors (each being a "Disinterested Director") prior to the time the
Interested Shareholder involved became an Interested Shareholder and such
business combination has been approved by a majority of the Disinterested
Directors and by a majority of the entire Board of Directors, (b) the
aggregate amount of the cash and the fair market value of consideration other
than cash to be received per share by holders of Common Stock in such business
combination shall be at least equal to the Specified Price (as hereinafter
defined) or (c) such business combination has been unanimously approved by the
Board of Directors and the Board has, in the faithful exercise of its
fiduciary duties to the holders of Common Stock, unanimously and expressly
determined
 
                                     S-87
<PAGE>
 
that the aggregate amount of the cash and the fair market value of the
consideration other than cash to be received per share by holders of Common
Stock in such business combination, although less than the Specified Price, is
nonetheless fair to all holders of Common Stock.
 
  As used above:
 
    "business combination" means (a) any merger or consolidation of Federal-
  Mogul and any subsidiary with or into any Interested Shareholder or any
  corporation which after such merger or consolidation would be an affiliate
  of an Interested Shareholder, (b) any sale lease exchange, mortgage,
  pledge, transfer or other disposition to any Interested Shareholder or its
  affiliate of assets of Federal-Mogul or any subsidiary having a fair market
  value of $1 million or more (except in the ordinary course of business and
  on an arm's-length basis), (c) the issuance or transfer by Federal-Mogul or
  any subsidiary (in one transaction or a series of related transactions) of
  any securities of Federal-Mogul or a subsidiary to any Interested
  Shareholder or its affiliate for cash, securities or property having a fair
  market value of $1 million or more, (d) the adoption of any plan or
  proposal for the liquidation or dissolution of Federal-Mogul as a result of
  which any Interested Shareholder or its affiliate would receive any assets
  of Federal-Mogul other than cash or (e) any reclassification of securities
  (including any reverse stock split) or recapitalization of Federal-Mogul or
  merger or consolidation of Federal-Mogul with any subsidiary or any similar
  transaction (whether or not with an Interested Shareholder) which has the
  effect, directly or indirectly, of increasing the proportion of outstanding
  shares of any equity security of Federal-Mogul or a subsidiary directly
  owned by an Interested Shareholder or its affiliate.
 
    "Interested Shareholder" means a person who on the record date for
  determining the shareholders entitled to vote on a business combination is
  (a) the beneficial owner of 10% or more of the outstanding shares of Common
  Stock, (b) an affiliate of Federal-Mogul and within two years prior to such
  record date beneficially owned 10% or more of the then outstanding shares
  of Common Stock or (c) an assignee or other successor to any shares of
  capital stock of Federal-Mogul which were within two years prior thereto
  beneficially owned by an Interested Shareholder and such assignment or
  succession shall have occurred in one or more transactions not involving a
  public offering.
 
    "Specified Price" means the highest of (a) the highest per share price
  paid or agreed to be paid by such Interested Shareholder to acquire
  beneficial ownership of any shares of Common Stock within the two-year
  period prior to the consummation of the business combination; (b) the per
  share book value of the Common Stock at the end of the fiscal month
  immediately preceding the consummation of such business combination; and
  (c) if the Common Stock of the Interested Shareholder is publicly traded,
  the price per share equal to the earnings per share of Common Stock for the
  four full consecutive fiscal quarters immediately preceding the record date
  for solicitation of votes on such business combination (or, if votes are
  not solicited on such business combination, immediately preceding the
  consummation of such business combination) multiplied by the ratio (if any)
  of the highest published sale price of the Interested Shareholder's common
  stock during its four fiscal quarters immediately preceding such date, to
  the earnings per share of common stock of the Interested Shareholder for
  such four fiscal quarters.
 
FEDERAL-MOGUL'S BYLAWS
 
  Federal-Mogul's Bylaws contain provisions that govern nominations of
directors by shareholders and presentation of business by shareholders for
consideration at the annual meeting of shareholders. Generally, a shareholder
must give notice of such nomination or business within 60 to 90 days prior to
such meeting, giving specified information as to the shareholder and as to the
person nominated and the business proposed to be brought before the meeting.
 
                                     S-88
<PAGE>
 
INCENTIVE STOCK PLANS
 
  Federal-Mogul's shareholders adopted Stock Option Plans in 1976 and 1984 and
a Performance Incentive Stock Plan in 1989, and the holders of Common Stock
and Series C Stock approved an Amended and Restated 1997 Long Term Incentive
Plan (the "1997 Long Term Incentive Plan") in 1998. These plans provide
generally for granting options to purchase shares of the Common Stock.
Restricted shares may be awarded under both the 1989 Plan and the 1997 Long
Term Incentive Plan, entitling holders to all the rights of Common Stock
shareholders, subject to certain transfer restrictions or forfeitures. Options
entitle employees and nonemployee directors to purchase shares at an exercise
price not less than 100% of the fair market value of the shares on the grant
date.
 
  The 1989 Performance Incentive Stock Plan and the 1997 Long Term Incentive
Plan additionally provide for the granting of performance unit awards
("PUA's") to eligible employees. These awards may be granted in the form of
Common Stock or units, the value of which are based on the market value of the
Common Stock. PUA's must relate to certain performance criteria established by
the Compensation Committee of the Board of Directors and are awarded on terms
and conditions fixed by the Committee on the date of grant. At November 11,
1998, 91,500 PUA's had been granted and 88,100 were outstanding.
 
TRUST PREFERRED SECURITIES
 
  In December 1997, Federal-Mogul's wholly-owned financing trust ("Affiliate")
completed a $575 million private issue of 11.5 million shares of 7.0% Trust
Convertible Preferred Securities ("TCP Securities") with a liquidation value
of $50 per convertible security. The net proceeds from the TCP Securities were
used to purchase an equal amount of 7.0% Convertible Junior Subordinated
Debentures ("Debentures") of Federal-Mogul. The TCP Securities represent an
undivided interest in the Affiliate's assets, with a liquidation preference of
$50 per security. Distribution on the TCP Securities are cumulative and will
be paid quarterly in arrears at an annual rate of 7.0%, and are included in
the consolidated statement of operations as a component of Other Expense, Net.
The Company has the option to defer payment of the distributions for an
extension period of up to 20 consecutive quarters.
 
  The TCP Securities are convertible, at the option of the holder, into
Federal-Mogul Common Stock at an initial conversion rate of .9709 shares of
Common Stock per TCP Security (an aggregate of 11,165,049 shares of Common
Stock), subject to adjustment in certain circumstances. The TCP Securities and
the Debentures will be redeemable, at the option of Federal-Mogul, on or after
December 6, 2000 at a Redemption Price, expressed as a percentage of principal
which is added to accrued and unpaid interest. The Redemption Price range is
from 104.9% on December 6, 2000 to 100.0% after December 1, 2007. All
outstanding TCP Securities and Debentures are required to be redeemed by
December 1, 2027. At November 11, 1998, 11,500,000 Convertible Preferred
Securities were outstanding.

                    CERTAIN UNITED STATES TAX CONSEQUENCES
                         TO NON-UNITED STATES HOLDERS
 
  The following is a general discussion of certain United States federal
income and estate tax consequences of the ownership and disposition of Common
Stock by a person that, for United States federal income tax purposes, is a
nonresident alien individual or foreign corporation (a "non-U.S. holder"). The
discussion does not consider specific facts and circumstances that may be
relevant to a particular non-U.S. holder's tax position. Accordingly, each
non-U.S. holder is urged to consult its own tax advisor with respect to the
United States tax consequences of the ownership and disposition of Common
Stock, as well as any tax consequences that may arise under the laws of any
state, municipality, foreign country or other taxing jurisdiction.
 
DIVIDENDS
 
  Dividends paid to a non-U.S. holder of Common Stock ordinarily will be
subject to withholding of United States federal income tax at a 30 percent
rate, or at a lower rate under an applicable income tax treaty that provides
for a reduced rate of withholding. However, if the dividends are effectively
connected with the conduct by the holder of a trade or business within the
United States, then the dividends will be exempt from the withholding tax
described above and instead will be subject to United States federal income
tax on a net income basis.
 
GAIN ON DISPOSITION OF COMMON STOCK
 
  A non-U.S. holder generally will not be subject to United States federal
income tax in respect of gain realized on a disposition of Common Stock,
provided that (a) the gain is not effectively connected with a trade or
business conducted by the non-U.S. holder in the United States and (b) in the
case of a non-U.S. holder who is an individual and who holds the Common Stock
as a capital asset, such holder is present in the United States for less than
183 days in the taxable year of the sale and other conditions are met and (c)
the Company is not nor has been a "United States real property holding
corporation" within the meaning of Section 897(c)(2) of the Code at any time
within the shorter of the five-year period ending on the date of disposition
or the non-U.S. holder's holding period and certain other conditions are met.
The Company does not believe that it is, or is likely to become, a "United
States real property holding corporation."
 
FEDERAL ESTATE TAXES
 
  Common Stock owned or treated as being owned by a non-U.S. holder at the
time of death will be included in such holder's gross estate for United States
federal estate tax purposes, unless an applicable estate tax treaty provides
otherwise.
 
U.S. INFORMATION REPORTING REQUIREMENTS AND BACKUP WITHHOLDING TAX
 
  U.S. information reporting requirements and backup withholding tax will not
apply to dividends paid on Common Stock to a non-U.S. holder at an address
outside the United States, except that with respect to payments made after
December 31, 1999, a non-U.S. holder will be entitled to such an exemption
only if it provides a Form W-8 (or satisfies certain documentary evidence
requirements for establishing that it is a non-United States person) or
otherwise establishes an exemption. As a general matter, information reporting
and backup withholding also will not apply to a payment of the proceeds of a
sale of Common Stock effected outside the United States by a foreign office of
a foreign broker. However, information reporting requirements (but not backup
withholding) will apply to a payment of the proceeds of a sale of Common Stock
effected outside the United States by a foreign office of a broker if the
broker (i) is a U.S. person, (ii) derives 50 percent or more of its gross
income for certain periods from the conduct of a trade or business in the
United States, (iii) is a "controlled foreign corporation" as to the United
States or (iv) with respect to payments made after December 31, 1999, a
foreign partnership that, at any time during its taxable year is 50% or more
(by income or capital interest) owned by U.S. persons or is engaged in the
conduct of a U.S. trade or business, unless the broker has documentary
evidence in its records that the holder is a non-U.S. holder and certain
conditions are met, or the holder otherwise establishes an exemption. Payment
by a United States office of a broker of the proceeds of a sale of Common
Stock will be subject to both backup withholding and information reporting
unless the holder certifies its non-United States status under penalties of
perjury or otherwise establishes an exemption.

  Federal-Mogul has also entered into an International Purchase Agreement (the
"International Purchase Agreement" and, together with the U.S. Purchase
Agreement, the "Purchase Agreements") with certain underwriters outside the
United States and Canada (the "International Managers" and, together with the
U.S. Underwriters, the "Underwriters"). Subject to the terms and conditions
set forth in the International Purchase Agreement, and concurrently with the
sale of 12,000,000 shares of Common Stock to the U.S. Underwriters pursuant to
the U.S. Purchase Agreement, Federal-Mogul has agreed to sell to the
International Managers, and the International Managers severally have agreed
to purchase, an aggregate of 2,000,000 shares of Common Stock. The offering
price per share and the total underwriting discount per share are identical
under the U.S. Purchase Agreement and the International Purchase Agreement.
 
  In each Purchase Agreement, the several U.S. Underwriters and the several
International Managers, respectively, have agreed, subject to the terms and
conditions set forth in such Purchase Agreement, to purchase all of the shares
of Common Stock being sold pursuant to such Purchase Agreement if any of such
shares of Common Stock being sold pursuant to such Purchase Agreement are
purchased. Under certain circumstances, the commitments of non-defaulting U.S.
Underwriters or International Managers (as the case may be) may be increased.
The sale of Common Stock to the U.S. Underwriters is conditioned upon the sale
of shares of Common Stock to the International Managers, and vice versa.
 
  The U.S. Underwriters and the International Managers have entered into an
intersyndicate agreement (the "Intersyndicate Agreement") that provides for
the coordination of their activities. Pursuant to the Intersyndicate
Agreement, the Underwriters are permitted to sell shares of Common Stock to
each other for purposes of resale at the public offering price set forth on
the cover page of this Prospectus Supplement, less an amount not greater than
the selling concession. Under the terms of the Intersyndicate Agreement, the
U.S. Underwriters and any dealer to whom they sell shares of Common Stock will
not offer to sell or sell shares of Common Stock to persons who are non-U.S.
or non-Canadian persons or to persons they believe intend to resell to persons
who are non-U.S. or non-Canadian persons, and the International Managers and
any dealer to whom they sell shares of Common Stock will not offer to sell or
sell shares of Common Stock to U.S. persons or Canadian persons or to persons
they believe intend to resell to U.S. persons or Canadian persons, except, in
each case, for transactions pursuant to the Intersyndicate Agreement.
 
  The U.S. Underwriters have advised Federal-Mogul that the U.S. Underwriters
propose initially to offer the shares of Common Stock to the public at the
public offering price set forth on the cover page of this Prospectus
Supplement and to certain dealers at such price less a concession not in
excess of $0.973 per share of Common Stock. The U.S. Underwriters may allow,
and such dealers may reallow, a discount not in excess of $0.10 per share of
Common Stock on sales to certain other dealers. After the public offering, the
public offering price, concession and discount may be changed.
 
  Federal-Mogul has granted an option to the U.S. Underwriters, exercisable
during the 30-day period after the date of this Prospectus Supplement, to
purchase up to an additional 1,800,000 shares of Common Stock at the public
offering price set forth on the cover page hereof, less the underwriting
discount. The U.S. Underwriters may exercise this option only to cover over-
allotments, if any, made on the sale of shares of Common Stock offered hereby.
To the extent that the U.S. Underwriters exercise this option, each U.S.
Underwriter will be obligated, subject to certain conditions, to purchase
approximately the number of additional shares of Common Stock proportionate to
such U.S. Underwriters' initial amount reflected in the foregoing table.
Federal-Mogul has also granted an option to the International Managers,
exercisable during the 30-day period after the date of this Prospectus
Supplement, to purchase up to an additional 300,000 shares of Common Stock to
cover over-allotments, if any, on terms similar to those granted to the U.S.
Underwriters.
 
  Federal-Mogul and certain of its executive officers have agreed that, except
under certain circumstances (including issuances of securities in connection
with acquisitions), they will not, directly or indirectly, for a period of 90
days following the date of the Prospectus Supplement, except with the prior
consent of Bear Stearns, on behalf of the Underwriters, sell, offer to sell,
grant any option for the sale of, or otherwise dispose of, any Common Stock,
except that Federal-Mogul may issue Common Stock or options for shares of
Common Stock issued pursuant to or sold in connection with any employee
benefit plan.

  In order to facilitate the Offerings, certain persons participating in the
Offerings may engage in transactions that stabilize, maintain or otherwise
affect the price of the Common Stock during and after the Offerings.
Specifically, the U.S. Underwriters may over-allot or otherwise create a short
position in the Common Stock for their own account by selling more shares of
Common Stock than have been sold to them by Federal-Mogul. The U.S.
Underwriters may elect to cover any such short position by purchasing shares
of Common Stock in the open market or by exercising the over-allotment option
granted to the U.S. Underwriters. In addition, such persons may stabilize or
maintain the price of the Common Stock by bidding for or purchasing shares of
Common Stock in the open market and may impose penalty bids, under which
selling concessions allowed to syndicate members or other broker-dealers
participating in the Offerings are reclaimed if shares previously distributed
in the Offerings are repurchased in connection with stabilization transactions
or otherwise. The effect of these transactions may be to stabilize or maintain
the market price of the Common Stock at a level above that which might
otherwise prevail in the open market. The imposition of a penalty bid may also
affect the price of the Common Stock to the extent that it discourages resales
thereof. No representation is made as to the magnitude or effect of any such
stabilization or other transactions. Such transactions, if commenced, may be
discontinued at any time.
 
  Certain of the U.S. Underwriters and their affiliates engage from time to
time in various general financing and banking transactions with, or provide
financial advisory services to, Federal-Mogul and its affiliates. Certain
affiliates of the U.S. Underwriters and the International Managers are lenders
under the Credit Agreements. Thus affiliates of certain of the U.S.
Underwriters and the International Managers will receive in the aggregate
proceeds from the Offerings in excess of 10% of the net proceeds of the
Offerings. Accordingly, the Offerings are being made in compliance with Rule
2710(c)(8) of the National Association of Securities Dealers, Inc. See "Use of
Proceeds."
 
  Federal-Mogul has agreed to indemnify the U.S. Underwriters and the
International Managers, against certain liabilities, including liabilities
under the Securities Act.
 
  Federal-Mogul estimates that it will spend approximately $850,000 for
printing, legal and accounting fees, and other expenses of the Offerings.

                                                 ANNEX I: THE COOPER ACQUISITION
 
  On October 9, 1998, the Company acquired the automotive division of Cooper
Industries, Inc. ("Cooper Automotive") for a total purchase price of $1.9
billion (the "Cooper Acquisition"). The Company also incurred approximately $25
million of fees and expenses (including $19.5 million of debt financing costs
and $5.5 million of direct transaction costs) in connection with the Cooper
Acquisition.*
 
                                    BUSINESS
 
  Cooper Automotive, comprised of the Cooper Automotive division (the Champion
spark plug group of companies) and the Moog Automotive division of Cooper
Industries, Inc., is a premier provider of leading brand name automotive
products to the aftermarket and OE market. Cooper Automotive manufactures and
distributes brake and friction products, chassis, ignition products, lighting
and wiper products under well-known brand names including Champion(R), Moog(R),
Anco(R), Abex(R), Wagner(R) and Zanxx(R). Among Cooper Automotive's largest
customers are AutoValue, Carquest, DaimlerChrysler, Ford, Fiat, General Motors
and NAPA (in alphabetical order).
 
  Cooper Automotive had 1997 revenues of $1.9 billion and operating earnings of
$177 million before nonrecurring charges. The following charts set forth Cooper
Automotive's sales by market segment, geographic region and manufacturing
division as a percentage of total sales for the year ended December 31, 1997.

 Friction and Brake Hard Parts
 
  Cooper Automotive manufactures and distributes Abex(R) friction material and
Wagner(R) brake components including master and wheel cylinders, calipers,
brake lines and hoses, drums, rotors and miscellaneous hardware and cables.
Abex(R) is the friction manufacturing unit that directly supplies the OE market
and the Wagner(R) unit with friction needs. As a result, the Wagner(R) unit is
a full line friction and brake hard part supplier to the aftermarket.
 
  The Cooper Automotive friction material business complements Federal-Mogul's
existing Ferodo friction business. Ferodo is a leader in the European friction
market and Abex(R) is a leader in the U.S. friction market. The Wagner(R) brake
hard parts business provides Federal-Mogul with a manufacturing base for
expanding sales of entire brake system packages to customers in both the OE
market and aftermarket.
 
 
  The Abex, Wagner and Ferodo businesses generated sales in excess of $1
billion in 1997. Federal-Mogul anticipates establishing a separate friction and
brake operating unit following the Cooper Acquisition.
 
 Lighting
 
  Cooper Automotive manufactures and distributes a variety of lighting
products. Under the Wagner(R) brand "bumper-to-bumper" lighting is provided to
both the OE market and aftermarket. This includes sealed beams, halogen
capsules, lighting modules for front and rear trim, and interior lighting. The
Blazer(R) brand is focused on

fog-type lights. The Wagner(R)/Blazer(R) unit is a leader in the North
American automotive lighting aftermarket. Zanxx(R) is a leader in the OE
market for connectors, sockets and switches for automotive lighting.
 
  Federal-Mogul supplies the heavy duty truck and trailer market with DOT-
regulated lighting under its Signal-Stat brand. The combination of the
Federal-Mogul and Cooper Automotive lighting businesses provides the Company
with the capability to offer total vehicular industry lighting system packages
to both the OE market and aftermarket.
 
 Chassis Parts
 
  Cooper Automotive manufactures and distributes Moog(R) steering and
suspension products and Precision(R) universal joints. Federal-Mogul currently
distributes purchased aftermarket chassis parts. The Cooper Acquisition will
establish Federal-Mogul as a basic manufacturer of chassis parts. Moog(R) and
Precision(R) maintain a leadership position in the North American aftermarket
with their "problem solver" applications for the installer.
 
  Cooper Automotive's chassis parts business enhances Federal-Mogul's growth
opportunities in the retail automotive parts market while allowing it to
maintain its strong position with wholesaler distributors. The growth of the
sport utility vehicle ("SUV") segment has also increased demand for
replacement chassis parts due to heavier vehicle weight, a greater number of
traditional chassis parts per vehicle and increased wear out rates.
 
  The expansion of Federal-Mogul's chassis product offering, coupled with
Federal-Mogul's wheel-end offering (anti-friction bearings and seals) and the
complete brake system offering will enable Federal-Mogul to provide a one-stop
shopping source for undercar parts to customers in the aftermarket.
 
 Ignition
 
  Cooper Automotive manufacturers and distributes spark plugs, diesel glow
plugs, ignition coils and wire and cable sets. Most of these products are sold
by Cooper Automotive under the widely-recognized Champion(R) brand name, with
some aftermarket wire and cable sold under the Belden(R) and PowerPath(R)
brand names. In addition to maintaining a significant presence in the
automotive ignition parts market, Cooper Automotive generates significant
revenues from sales of ignition-type products for aviation-related
applications.
 
  The Cooper Automotive ignition product line complements Federal-Mogul's
powertrain capabilities, thereby enhancing the Company's ability to capitalize
on opportunities presented by engine management and environmental regulations
that place a premium on ignitability, heat and gas control. Federal-Mogul's
focus on ignition and powertrain components and systems provides it with
opportunities to benefit from the increased demand for cleaner and more
efficient engines.
 
 
Wiper Blades
 
  Cooper Automotive manufactures and distributes wiper arms and blades in the
North American and European aftermarket under the Anco(R) brand name. Federal-
Mogul believes that demand for wiper arms and blades has been favorably
impacted in recent years from the need for a third arm/blade on SUVs and new
arm/blades that can conform to changes in car slope design. Federal-Mogul
believes that the addition of a wiper arms/blade product line with strong
retail brand name recognition can facilitate its ability to expand retail
sales of its other products, such as gaskets, friction and certain suspension
components. The Anco(R) brand also enjoys a significant position among OE
manufacturers, which may enhance the Company's ability to market complete
wiper systems.
 
STRATEGIC RATIONALE AND SYNERGIES
 
  The Cooper Acquisition is expected to further the Company's strategic
objective of expanding manufactured product lines to engineered systems and
modules and accelerating the Company's worldwide growth. Cooper Automotive
brings additional leading brand names, new strategically compatible product
lines, additional customers and enhanced distribution channel penetration. The
Cooper Acquisition also broadens the Company's
 
                                      I-2
<PAGE>
 
brake and friction and lighting product lines as well as adds ignition
products and wiper blades to its range. Also, the combination of Federal-
Mogul's wheel end bearing and seal business with chassis and brake system
products offers customers the potential of a single consolidated vendor base
for undervehicle parts.
 
  Management believes that significant benefits result from the ability to
penetrate its existing customer base for distribution of Cooper Automotive
products. In particular, the Company's relationships with OE manufacturers,
heavy duty equipment and international customers represent opportunities for
expansion of the market for Cooper Automotive products.
 
  Management also believes that integration of the Company's operations with
those of Cooper Automotive will provide significant opportunities for
synergies and cost savings. The Company currently anticipates pre-tax synergy
and cost benefits of approximately $94 million in 1999; $154 million in 2000;
and $161 million in 2001. In connection with realization of synergies, at
closing Federal-Mogul recorded $88 million in pre-tax reserves for severance
and exit costs, in addition to certain purchase accounting valuation
adjustments, and expects to incur $23 million in integration costs over the
subsequent 18 months. Specific cost savings targeted by management to realize
synergies from the Cooper Acquisition include:
 
    Manufacturing. Consolidation of the friction products operations,
  combining Cooper Automotive's EIS(R), Wagner(R) and Abex(R) operations with
  Federal-Mogul's Ferodo(R) operations to rationalize manufacturing sites,
  transfer assembly labor to expanding lower cost facilities and reduce
  headcount.
 
    Sales and Marketing. Consolidation and streamlining of the combined sales
  and marketing personnel to take advantage of overlaps and economies of
  scale.
 
    Distribution, Sourcing and Administration. Consolidation of the
  aftermarket company based distribution network, transfer from "buy" to
  "make" sourcing and consolidation of both the administration and
  headquarters of Cooper Automotive located in St. Louis, Missouri to
  Federal-Mogul's Southfield, Michigan, headquarters.
 
THE COMBINED COMPANY
 
  On a pro forma basis (after giving effect to the Cooper Acquisition, the
acquisitions of T&N and Fel-Pro and the disposition of the T&N Bearings
Business and the Fel-Pro Chemical Business, as if they had occurred on January
1, 1997), Federal-Mogul's total sales for 1997 were $6.6 billion and its net
earnings before extraordinary item, non-recurring charges and the Offerings
adjustments was $12.0 million.
 
  Consummation of the Cooper Acquisition substantially expands the Company's

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
  The information and discussion that follows should be read in conjunction
with the Combined Financial Statements of Cooper Automotive and related notes
thereto (the "Cooper Automotive Financial Statements"), appearing elsewhere in
Annex I of this Prospectus Supplement.
 
OVERVIEW
 
  Over the last two years, Cooper Automotive has been engaged in a review and
evaluation of its operations and as a result has recorded adjustments to the
carrying value of assets and accruals for projects to which management is
committed. During early 1998, Cooper Automotive completed the exit of
remanufacturing activities and all product lines included in the temperature
control business. The temperature control businesses were exchanged for the
brake products business owned by Standard Motor Products ("SMP"), and the
other remanufacturing businesses were sold for $4 million. During 1997,
adjustments to the carrying value of the assets were recorded and no further
adjustments were necessary upon completion of the transactions disposing of
the businesses. On an annual basis, the revenues for the SMP brake products
business of approximately $150 million are expected to exceed the revenues of
the disposed businesses. Incremental earnings are anticipated in 1998 from the
higher-margin brake business and as consolidation activities are completed
during 1998. However, the temperature control business was a seasonal business
with a majority of the sales occurring in the second and third quarter of each
year. Therefore, during 1998, the exchange resulted in lower revenues in the
second and third quarter and is expected to result in higher revenues in the
fourth quarter.
 
NINE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED WITH NINE MONTHS ENDED SEPTEMBER
                                   30, 1997
 
RESULTS OF OPERATIONS
 
 Revenues
 
  Revenues for the first nine months of 1998 totaled $1,400.8 million, a 2%
decrease from the $1,423.8 million in the first nine months of 1997.
Acquisitions and divestitures had a nominal effect on revenues. Increased
sales to worldwide original equipment manufacturers and improved steering and
suspension sales were more than offset by weak domestic aftermarket demand in
most product lines. The net impact of the exchange of Cooper Automotive's
temperature control business for the brake business of Standard Motor Products
("SMP Exchange") resulted in lower revenues during the period as a result of
disruption in the marketplace during the transition and the seasonal nature of
the temperature control business which typically had relatively strong second
and third quarter sales each year. Also, revenues were affected by the
bankruptcy of a large customer in the first quarter of 1998. The customer was
converted to a cash basis during the first quarter of 1998, significantly
reducing sales volume compared to 1997. Ongoing market consolidation continued
to impact revenues through pricing pressure and other competitive conditions.
 
 Cost of Sales
 
  Cost of sales as a percentage of revenues improved to 68.1% during the first
nine months of 1998 from 69.2% in 1997. The improvement was the result of the
swap of Cooper Automotive's lower margin temperature control product line for
the brake products business of SMP. Also contributing to the lower cost of
sales percentage was the favorable effect on product mix from increased sales
of friction products to the OE market and the heavy-duty aftermarket, which
carries a higher margin.
 
 Selling and Administrative Expenses
 
  Selling and administrative expense as a percentage of revenues decreased to
18.5% during the first nine months of 1998 compared to 18.7% during the first
nine months of 1997. Actual selling and administrative expenses were reduced
in 1998 reflecting the benefits of certain sales and marketing restructuring,
reduced spending for advertising, promotions and customer changeover costs.

 Goodwill Amortization
 
  Amortization of goodwill was $24.7 million and $24.5 million, respectively,
for the first nine months of 1998 and the first nine months of 1997,
reflective of the absence of significant acquisitions.
 
 Nonrecurring Charges
 
  During the first nine months of 1997, Cooper Automotive recorded charges of
$43.4 million including adjustments to the carrying value of assets of $27.6
million and accruals of continuing obligations for replaced information
systems and facility consolidations.
 
 Other Expense, net
 
  Other expense, net, decreased $2.1 million during the first nine months of
1998 compared to the same period in 1997, primarily due to a decrease in the
actuarial expense for post-retirement benefits other than pensions.
 
 Interest Expense
 
  Interest expense decreased $0.4 million during the first nine months of 1998
compared to the first nine months of 1997, primarily due to lower levels of
outstanding debt.
 
 Income Tax Expense
 
  The effective tax rate decreased to 41.5% in 1998 from 45.2% in 1997. The
decrease was primarily attributable to the increase in income in 1998 reducing
the impact of nondeductible goodwill on the effective tax rate. Net income
increased 76.5% to $90.9 million during the first nine months of 1998 from
$51.5 million in 1997. The increase was due to the nonrecurring charges in
1997 and the lower effective tax rate in 1998.
 
  YEAR ENDED DECEMBER 31, 1997 COMPARED WITH YEAR ENDED DECEMBER 31, 1996 AND
    YEAR ENDED DECEMBER 31, 1996 COMPARED WITH YEAR ENDED DECEMBER 31, 1995
 
 Revenues
 
  Revenues decreased $30.0 million to $1.87 billion in 1997, a decrease of
1.6% from 1996 revenues of $1.90 billion. Excluding acquisitions, revenues
declined $41.7 million, or 2.2%. Sales to OE manufacturers improved in 1997
with the increased production levels of vehicles containing Cooper Automotive
products. Sales in the aftermarket were hampered by weak demand in most
product lines. Temperature control product sales and remanufactured product
lines declined primarily due to competitive price pressures. Wiper volume
declined significantly in the first half of 1997 as mild weather patterns
impacted winter-related products. In addition, the public announcement of the
SMP Exchange contributed to a significant reduction in temperature control
product sales. Revenues increased $144.4 million to $1.90 billion in 1996, an
increase of 8.2% over 1995 revenues of $1.76 billion. Cooper Automotive's
acquisitions accounted for $55.3 million of the increase in revenues. Harsh
winter weather and lean distributor inventories boosted domestic aftermarket
demand for wiper blades and ignition products in early 1996. New customers for
lighting products, partial recovery from the 1995 economic downturn in Mexico
and the increased placement of products on new vehicles and additional light
vehicle production also increased revenues in 1996 compared to 1995. Partially
offsetting these increases was a decline in sales of temperature control
products as a result of a mild summer, a decline in domestic sales of heavy
duty brake components as a result of decreases in OE production and lower
European aftermarket sales influenced by weak economic conditions.
 
 Cost of Sales
 
  Cost of sales as a percentage of revenues improved slightly in 1997 to 69.1%
from 69.2% in 1996. The improvement reflects the impact of the write-down of
brake assets and other actions to reduce manufacturing
 
                                      I-7
<PAGE>
 
costs, partially offset by the unfavorable effect on product mix of lower
sales to the aftermarket, which carry a higher margin. Cost of sales as a
percentage of revenues increased slightly in 1996 to 69.2% compared to 69.1%
in 1995. The slightly higher percentage reflects the unfavorable effect on
product mix from lower sales of higher margin heavy-duty brake components and
lower aftermarket sales in Europe.
 
 Selling and Administrative Expense
 
  Selling and administrative expense remained flat as a percentage of 1997 and
1996 revenues at 18.9%, despite the reduction in revenues, reflecting efforts
to control costs and the benefits from restructuring certain sales, marketing
and distribution activities. Selling and administrative expenses as a
percentage of revenues increased to 18.9% in 1996 from 18.5% in 1995. The
increase resulted from higher advertising, promotion and customer changeover
costs in 1996.
 
 Goodwill Amortization
 
  Goodwill amortization declined to $32.7 million in 1997 from $33.6 million
in 1996, primarily as a result of the write-down in 1996 of goodwill related
to certain Wagner brake product lines. Goodwill amortization increased to
$33.6 million in 1996 from $32.9 million in 1995 primarily as a result of the
February 1996 acquisition of Blazer International Corp.
 
 Nonrecurring Charges
 
  During 1997, Cooper Automotive recorded charges of $55.9 million including
adjustments to the carrying value of assets of $30.6 million, accruals of
continuing obligations for replaced information systems and facility
consolidations of $12.8 million and an increase in the accrual for doubtful
accounts for the bankruptcy of a large customer of $12.5 million. During 1996,
Cooper Automotive initiated a strategic review of most of its businesses and
recorded an $85.3 million asset write-down and a $16.7 million in charges
primarily related to facility closings and consolidations. A majority of the
consolidations were announced prior to the end of each year. Cash expenditures
related to the payout of accrued severance and other expenditures related to
the committed consolidations in the following year are not significant.
 
 Other Expense
 
  Other expense, net, in 1997 increased $1.2 million compared to 1996. The
decrease of $1.0 million in the actuarial expense for post-retirement benefits
other than pensions was more than offset by increases in miscellaneous other
expenses. Other expense, net, in 1996 and 1995 were similar amounts with the
increase in 1996 of $0.7 million in actuarial expense for post-retirement
benefits offset by an increase in other income.
 
 Interest Expense
 
  Interest expense increased $0.4 million in 1997 compared to 1996 and
decreased $0.6 million in 1996 as compared to 1995. The increase in 1997 was
primarily attributable to higher levels of short-term debt at international
locations, partially offset by decreases in industrial development bonds. The
decrease in 1996 versus 1995 is primarily due to lower levels of outstanding
debt.
 
 Income Tax Expense
 
  The effective tax rate decreased from 64.1% in 1996 to 45.3% in 1997. The
1996 rate was higher than normal due to the asset write-down which included
the write-off of nondeductible goodwill. Excluding the impact of this write-
down, the effective rate was 48.0%. The decrease in the effective rate from
48.0% in 1996 to 45.3% in 1997 was primarily attributable to the increase in
income in 1997 reducing the impact of nondeductible goodwill on the effective
tax rate.
 
 
                                      I-8
<PAGE>
 
 Net Income
 
  Net income in 1997 increased to $65.6 million from $27.5 million in 1996.
The increase was due to lower nonrecurring charges in 1997. The effective tax
rate increased to 64.1% in 1996 from 46.7% in 1995, primarily due to the
write-down of goodwill that was nondeductible for income tax purposes. Net
income in 1996 decreased to $27.5 million from $90.3 million in 1995,
primarily due to the nonrecurring charges in 1996.
 
LIQUIDITY AND CAPITAL RESOURCES
 
 Operating Working Capital (For purposes of this discussion, operating working
capital is defined as   receivables and inventories less accounts payable)
 
  During the first nine months of 1998, operating working capital increased
$31.6 million. A $27.5 million increase in receivables was the primary reason
for the higher operating working capital.
 
  In 1997, operating working capital decreased $1.2 million as a result of a
$29.5 million decrease in accounts receivable, a $12.6 million increase in
inventories and a $15.7 million decrease in accounts payable. The decrease in
accounts receivable reflects the lower sales in the fourth quarter of 1997
compared to 1996 and an increase in the allowance for doubtful accounts in
1997 for a major customer who filed for bankruptcy in the first quarter of
1998. The increase in inventories relates to a build up in inventories to
support customer service during the implementation of integrated business
systems during 1997 and 1998 at one of Cooper Automotive's divisions. In 1996,
operating working capital increased $8.3 million as a result of an increase in
accounts receivable of $28.8 million, a decrease in inventory of $1.8 million
and an increase in accounts payable of $18.7 million. The increase in accounts
receivable reflects higher sales in the fourth quarter of 1996 compared to
1995 and an increase in days receivables were outstanding in 1996.
 
 Cash Flow Provided from Operating Activities
 
  During the first nine months of 1998, net cash provided by operating
activities totaled $104.8 million. These funds were primarily used to finance
$43.7 million of capital expenditures and net financing activities of $36.9
million. During the first nine months of 1997, net cash provided by operating
activities of $107.9 million was used to finance capital expenditures of $58.7
million, a small acquisition of $12.2 million and net financing activities of
$26.8 million.
 
  Net cash provided by operating activities during the year ended December 31,
1997 totaled $157.5 million. These funds were used to finance net cash
outflows for acquisitions of $20.1 million and capital expenditures of $78.4
million. Net cash provided by operating activities during the year ended
December 31, 1996 totaled $173.6 million. The cash generated from operating
activities was utilized to finance acquisitions of $55.4 million and capital
expenditures of $87.1 million. Net cash flows provided by operating activities
during the year ended December 31, 1995 totaled $188.9 million. This cash flow
was used to fund acquisitions of $8.9 million and capital expenditures of
$85.7 million.
 
  In connection with accounting for business combinations utilizing the
purchase accounting method, Cooper Automotive records, to the extent
appropriate, accruals for the costs of closing duplicate facilities, severing
redundant personnel and integrating the acquired business into existing Cooper
Automotive operations. Cash flow from operating activities for each of the
three years in the periods ended December 31, 1997, is reduced by the amounts
expended on the various accruals established in connection with each
acquisition. At December 31, 1997, Cooper Automotive had accruals totaling
$19.8 million related to these activities. Cooper Automotive spent $7.1
million in the first nine months of 1998 and $4.4 million, $20.7 million and
$39.1 million in 1997, 1996 and 1995, respectively. Spending for the balance
of 1998 and future years is not expected to be at the 1995 and 1996 levels, as
most of the major projects related to earlier acquisitions have been completed
and recent acquisitions do not involve significant restructuring activities.
 
                                      I-9
<PAGE>
 
  For purposes of Cooper Automotive's historical financial statements,
identifiable debt was allocated to Cooper Automotive during each period with
all of Cooper Automotive's combined positive or negative cash flows being
treated as cash transferred to or from Cooper. The specifically identifiable
industrial revenue bonds (the "IRB") of $1.5 million at September 30, 1998 and
$3.5 million and $7.0 million at December 31, 1997 and 1996, respectively, and
specifically identifiable international debt was assigned to Cooper
Automotive. Cooper Automotive also has international short-term borrowing
facilities under which $35.5 million and $6.1 million was outstanding at
December 31, 1997 and 1996, respectively. The outstanding balance of the
international short-term borrowings at September 30, 1998 was $2.5 million.
 
 Capital Expenditures and Commitments
 
  Capital expenditures on projects to reduce product costs, improve product
quality, increase manufacturing efficiency and operating flexibility, or
expand product capacity were $43.7 million during the first nine months of
1998, $78.4 million in 1997, $87.1 million in 1996 and $85.7 million in 1995.
Projected capital expenditures for 1998 are anticipated to approximate 1997
expenditures. The 1998 anticipated capital spending represents approximately
41% for various cost-reduction and capacity-maintenance projects, including
machinery and equipment modernization and enhancement and computer hardware
and software projects, 35% for capacity expansion, 7% related to environmental
matters and 17% for other items.
 
 Foreign Currency Risk
 
  Cooper Automotive uses forward foreign currency exchange contracts to reduce
the risk associated with changes in the exchange rates for firm commitments
and anticipated sales or purchases where a product is manufactured or
purchased in one country and sold or consumed in the manufacturing process in
another country. Cooper Automotive's policy is to hedge firm commitments to
eliminate this risk if natural hedges do not exist. Anticipated sales or
purchases are hedged at the discretion of the operating business.
Substantially all of Cooper Automotive's forward contracts expire within one
year. At December 31, 1997, insignificant amounts of anticipated sales and
purchases were hedged. Management believes that the effects of currency
movements on the respective underlying hedged transactions offset any gain or
loss on forward exchange contracts.
 
COOPER ASBESTOS LIABILITY
 
  Companies within Cooper Automotive are among a large number of defendants in
a number of lawsuits brought by claimants alleging injury due to exposure to
asbestos. Federal-Mogul believes the relevant entities have substantial
defenses to liability and adequate insurance coverage for defense and
indemnity. While the outcome of litigation cannot be predicted with certainty,
management believes that asbestos claims pending against companies within
Cooper Automotive as of September 30, 1998 will not have a material effect on
Federal-Mogul's financial position.
 
YEAR 2000 COSTS
 
  The Year 2000 issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Cooper Automotive
has established teams that have completed awareness programs and assessment
projects to address the Year 2000 issue including information technology
("IT") and non-IT systems. Cooper Automotive's Moog Division is implementing
new enterprise systems, and the Cooper Automotive Division is revising or
upgrading existing software so that its computer systems will properly utilize
dates beyond December 31, 1999. Cooper Automotive presently believes that with
modifications to existing software and conversion to new software and systems,
the Year 2000 issue can be mitigated. However, if such modifications and
conversions are not made, or are not completed timely, the Year 2000 issue
could cause production interruptions that could have a material impact on the
operations of Cooper Automotive.
 
  Cooper Automotive has initiated formal communications with a substantial
majority of its significant suppliers and large customers to determine their
plans to address the Year 2000 issue. While Cooper Automotive
 
                                     I-10
<PAGE>
 
expects a successful resolution of all issues, there can be no guarantee that
the systems of other companies on which the Cooper Automotive systems rely
will be converted in a timely manner, or that a failure to convert by a
supplier or customer, or a conversion that is incompatible with Cooper
Automotive's systems, would not have a material adverse effect on Cooper
Automotive. Cooper has determined it has no exposure to contingencies related
to the Year 2000 issue for products it has sold.
 
  Cooper Automotive has contracts in place with external resources and has
allocated internal resources to reprogram or replace and test the software and
systems for Year 2000 modifications. Cooper Automotive's management believes
that, at December 31, 1997, the business was greater than fifty percent
complete in its efforts to convert software or install systems that are Year
2000 compliant. While most efforts are anticipated to be completed by the end
of 1998, it is likely that certain efforts will be delayed into early 1999.
The total cost of the Year 2000 project is estimated to be approximately $41
million and is being funded through operating cash flows. Of the total project
cost, approximately $36 million is attributable to the purchase of new
software and systems which will be capitalized. The remaining $5 million
represents maintenance and repair of existing systems and will be expensed as
incurred. Cooper Automotive expects the majority of the costs will be in 1998,
and any remaining costs incurred in 1999 to be immaterial. As of September 30,
1998, Cooper Automotive had incurred and expensed the substantial majority of
the $5 million estimated costs related to the completed awareness program and
assessment project and the implementation of the remediation plan.
 
  The costs of the project and the date on which Cooper Automotive plans to
complete the Year 2000 modifications are based on management's best estimates,
which were derived utilizing numerous assumptions of future events including
the continued availability of certain resources, third party modification
plans and other factors. However, there can be no guarantee that these
estimates will be achieved and actual results could differ materially from
those plans. Specific factors that might cause such material differences
include, but are not limited to, the availability and cost of personnel
trained in this area, the ability to locate and correct all relevant computer
codes and similar uncertainties.

                        REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors
Cooper Industries, Inc.
 
  We have audited the accompanying combined balance sheets of the Cooper
Automotive and Moog Automotive Divisions (the "Automotive Divisions") of
Cooper Industries, Inc. (the "Company") as of December 31, 1997 and 1996, and
the related combined income statements and statements of cash flows for each
of the three years in the period ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the combined financial position of the Automotive
Divisions at December 31, 1997 and 1996, and the combined results of their
operations and their cash flows for each of the three years in the period
ended December 31, 1997, in conformity with generally accepted accounting
principles.

                AUTOMOTIVE DIVISIONS OF COOPER INDUSTRIES, INC.
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
 
NOTE 1: AUTOMOTIVE DIVISIONS
 
  The accompanying financial statements reflect a combination of the assets,
liabilities and operations of the Cooper Automotive and Moog Automotive
Divisions (the "Automotive Divisions") of Cooper Industries, Inc. ("Cooper").
Historically, the Automotive Divisions have been included in the consolidated
financial statements of Cooper on a divisional basis. The divisional basis
includes separate operating units in the United States and separate legal
entities or separate operating units of a holding company in international
locations. The business units that comprise the Automotive Divisions
(including the Automotive Divisions' headquarters) operate with complete
financial and operations staff on a decentralized basis. Cooper provides
certain centralized services for employee benefits administration, cash
management, risk management, legal services, public relations, domestic tax
reporting and internal and external audit. Cooper bills the Automotive
Divisions for all direct costs incurred on behalf of the Automotive Divisions.
General corporate, accounting, tax, legal and other administrative costs that
are not directly attributable to the operations of the Automotive Divisions
have been allocated based on a ratio of the Automotive Divisions' revenues to
Cooper's consolidated revenues. Management believes that this allocation
method provides the Automotive Divisions with a reasonable amount of such
expenses.
 
  The accompanying combined financial statements include the accounts of the
Automotive Divisions as described above. These statements are presented as if
the Automotive Divisions had existed as an entity separate from its parent,
Cooper, during the period presented and include the assets, liabilities,
revenues and expenses that are directly related to the Automotive Divisions'
operations. Because all of the Automotive Divisions' domestic results and, in
certain cases, foreign results were included in the consolidated financial
statements of Cooper on a divisional basis, there are no separate meaningful
historical equity accounts for the Automotive Divisions.
 
  In addition to the domestic debt related to industrial revenue bonds, the
Automotive Divisions' separate international debt and related interest expense
have been included in the combined financial statements. Because the
Automotive Divisions are fully integrated into Cooper's worldwide cash
management system, all of their cash requirements are provided by Cooper and
any excess cash generated by the Automotive Divisions is transferred to
Cooper.
 
NOTE 2: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Combination: The combined financial statements include the
accounts of the Cooper Automotive and Moog Automotive Divisions of Cooper,
which comprised Cooper's Automotive Products Segment. All transactions between
the two divisions have been eliminated. Affiliated companies are accounted for
on the equity method where the Automotive Divisions own more than 20% but less
than 50% of the affiliate unless significant economic, political or
contractual considerations indicate that the cost method is appropriate.
 
  Use of Estimates: The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Cash Equivalents: For purposes of the combined statements of cash flows, all
investments purchased with original maturities of three months or less are
considered cash equivalents.

  Inventories: Inventories are carried at cost or, if lower, net realizable
value. Cost is determined using the first-in, first-out (FIFO) method.
 
  Property, Plant and Equipment: Property, plant and equipment are stated at
cost. Depreciation is provided over the estimated useful lives of the related
assets using primarily the straight-line method. This method is applied to
group asset accounts, which in general have the following lives: buildings --
10 to 40 years; machinery and equipment -- 3 to 20 years; and tooling, dies,
patterns and other -- 5 to 10 years.
 
  Intangibles: Intangibles consist primarily of goodwill related to purchase
acquisitions. Goodwill is being amortized over 40 years from the respective
acquisition dates. The carrying value of goodwill is reviewed at the lowest
level feasible whenever there are indications that the goodwill may be
impaired. If this review indicates that goodwill will not be recoverable, as
determined based on undiscounted cash flows over the remaining amortization
periods, the carrying value of the goodwill will be reduced by the estimated
shortfall in discounted cash flows.
 
  Derivative Financial Instruments: On a recurring basis, foreign currency
forward exchange contracts and commodity contracts are entered into to reduce
risks of adverse changes in foreign exchange rates and commodity prices. All
contracts are hedges of actual or anticipated transactions with the gain or
loss on the contract recognized in the same period and in the same category of
income or expense as the underlying hedged transaction. The Automotive
Divisions do not enter into speculative derivative transactions or hedges of
anticipated transactions unless there is a high probability the transactions
will occur. Due to the short term of contracts and a restrictive policy,
contract terminations or anticipated transactions that do not occur are rare
and insignificant events that are accounted for through income in the period
they occur.
 
NOTE 3: NONRECURRING CHARGES
 
  During 1997, the Automotive Divisions incurred charges of $43.4 million
($26.5 million after income taxes) for actions management committed to during
the period after concluding an evaluation of certain sales, marketing and
distribution activities and information systems relating to year 2000
compliance efforts. The 1997 charges include adjustments to the carrying value
of assets of $30.6 million and accruals for obligations for replaced systems
and facility consolidations of $12.8 million. Nonrecurring charges in 1997
also include $12.5 million ($7.6 million after income taxes) related to a
customer that filed bankruptcy subsequent to December 31, 1997.
 
  The Automotive Divisions have begun a consolidation of certain sales,
marketing and distribution activities. Adjustments to the carrying value of
assets and accruals were recorded for projects committed to by management.
Severance and certain other costs related to projects committed to by
management are not expensed until the affected employees are notified. A
majority of the consolidations have been announced and such costs were accrued
and expensed during 1997. The remaining committed but unannounced
consolidations are not anticipated to result in significant additional
expenses.
 
  During 1997, Cooper began negotiations with Standard Motor Products, Inc.
("SMP") to exchange the Moog Automotive Division's temperature control
business for the brake products business owned by SMP. The 1997 nonrecurring
charge includes adjustments to the carrying value of the assets of the Moog
Automotive Division's remanufacturing businesses, including a portion of the
temperature control business, which were in the process of being divested.
Effective March 28, 1998, the Automotive Divisions completed the exchange of
the automotive temperature control business for the brake products business of
Standard Motor Products. For accounting purposes, the exchange transaction is
recorded as the sale of the Automotive Divisions' temperature control business
and the purchase of the Standard Motor Products' brake business. The fair
market values of the temperature control business assets were equal to the net
book value of the assets after the write-down of the

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
assets in 1997. The acquisition cost of the brake business assets was
approximately $81 million, subject to adjustment based on the actual book
value of certain assets at the acquisition date. In February 1998, the
Automotive Divisions also completed the sale of the constant velocity joint
remanufacturing business for approximately $4 million.
 
  During 1997, the Automotive Divisions also assessed the impact of existing
system capabilities to function at the turn of the century. The Moog
Automotive Division is implementing new enterprise systems, and the Cooper
Automotive division is revising or upgrading existing software to be year 2000
compliant. The Moog Division began the rollout of new enterprise-wide software
in 1997 and anticipates completion of the rollout in 1998. Where possible,
businesses have abandoned homegrown or highly customized applications and
purchased year 2000 compliant replacements or upgrades. In some situations,
operations within a business abandoned existing software and migrated to
consolidated hardware and software that is year 2000 compliant. The Automotive
Divisions recorded a $15.1 million charge in 1997 primarily related to the
adjustment in the carrying value of abandoned hardware and software. While
depreciation and amortization are reduced by the effect of the write-down,
depreciation and amortization of new systems and equipment, as well as
expenses incurred to revise current software to be year 2000 compliant, and
implementation costs of new systems, are likely to exceed the reduction in
depreciation and amortization in most future periods.
 
  During the third quarter of 1996, the Automotive Divisions completed a
strategic review of their brake business, resulting in a write-down of
approximately 21% of the long-lived assets of the business. The Wagner brake
product lines, acquired as part of the McGraw-Edison acquisition in 1985, were
subjected to intense competitive pricing and anticipated profitability
improvements during 1996 were not being realized. As a result of the review of
the Wagner brake products, the Automotive Divisions replaced Wagner technology
with technology acquired in the 1994 acquisition of Abex Friction Products.
Based on the strategic review, the Automotive Divisions concluded that the
projected undiscounted cash flows of certain Wagner product lines would not
recover the carrying value of the long-lived assets and goodwill associated
with these product lines. Accordingly, the Automotive Divisions recorded an
$85.3 million write-down ($64.4 million net of income taxes), including $31.5
million in goodwill, in 1996. The write-down reduced depreciation and
amortization costs by approximately $3.6 million, net of tax, in 1997. The
Automotive Divisions have incurred expenses executing the revised brake
strategy, which have offset some of the benefit of the reduced depreciation
and amortization in 1997.
 
  During 1996, the Automotive Divisions initiated a strategic review of most
of their businesses. As a result of those actions, the Automotive Divisions
incurred nonrecurring charges of $16.7 million ($10.2 million net of income
taxes) during 1996 primarily related to costs incurred on facility closings
and consolidations. The Automotive Divisions anticipate future cost savings
from the facility closings and consolidations; however, the amounts are not
quantifiable with any degree of accuracy. The nonrecurring charges of $16.7
million have an insignificant effect on future earnings, and expenditures
beyond 1996 were insignificant.
 
NOTE 4: ACQUISITIONS AND DIVESTITURES
 
  The Automotive Divisions completed two product-line acquisitions in 1997 and
1996 and one small product-line acquisition in 1995. The 1997 acquisitions had
an aggregate cost of $20.1 million and $14.0 million of goodwill was recorded,
on a preliminary basis, with respect to the acquisitions. The total cost of
the 1996 acquisitions was approximately $54.1 million and $36.1 million of
goodwill was recorded with respect to the acquisitions. The 1995 product-line
acquisition had a cost of $10.1 million. A total of $1.4 million of goodwill
was recorded with respect to the acquisition.
 
  The acquisitions have been accounted for as purchases and the results of the
acquisitions are included in the combined income statements since the
respective acquisition dates.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
  At December 31, 1997, the Automotive Divisions had accruals of $.9 million
with respect to potential product liability claims and $24.8 million with
respect to potential environmental liabilities, including $14.0 million
classified as a long-term liability, based on the Automotive Divisions'
current estimate of the most likely amount of losses that it believes will be
incurred.
 
  The product liability accrual consists of $.3 million of known claims with
respect to ongoing operations, $.2 million of known claims for previously
divested operations and $.4 million which represents an estimate of claims
that have been incurred but not yet reported. While the Automotive Divisions
are generally self-insured with respect to product liability claims, the
Automotive Divisions have insurance coverage for individual 1997 claims above
$3.0 million. Insurance levels have varied from year to year.
 
  Environmental remediation costs are accrued based on estimates of known
environmental remediation exposures. Such accruals are adjusted as information
develops or circumstances change. The environmental liability accrual includes
$13.5 million related to sites owned by the Automotive Divisions and $11.3
million for retained environmental liabilities related to sites previously
owned by the Automotive Divisions and third-party sites where the Automotive
Divisions were a contributor. Third-party sites usually involve multiple
contributors where the Automotive Divisions' liability will be determined
based on an estimate of the Automotive Divisions' proportionate responsibility
for the total cleanup. The amounts actually accrued for such sites are based
on these estimates as well as an assessment of the financial capacity of the
other potentially responsible parties.
 
  It has been the Automotive Divisions' consistent practice to include the
entire product liability accrual and a significant portion of the
environmental liability accrual as current liabilities, although only
approximately 10-20% of the balance classified as current will be spent on an
annual basis. The annual effect on earnings for product liability is
essentially equal to the amounts disbursed. In the case of environmental
liability, the annual expense is considerably smaller than the disbursements,
since the vast majority of the Automotive Divisions' environmental liability
has been recorded in connection with acquired companies. The change in the
accrual balances from year to year reflects the effect of acquisitions and
divestitures as well as normal expensing and funding.
 
  The Automotive Divisions have not utilized any form of discounting in
establishing its product or environmental liability accruals. While both
product liability and environmental liability accruals involve estimates that
can have wide ranges of potential liability, the Automotive Divisions have
taken a proactive approach and have managed the costs in both of these areas
over the years. The Automotive Divisions do not believe that the nature of
their products, production processes, or materials or other factors involved
in the manufacturing process subject the Automotive Divisions to unusual risks
or exposures for product or environmental liability. The Automotive Divisions'
greatest exposure to inaccuracy in their estimates is with respect to the
constantly changing definitions of what constitutes an environmental liability
or an acceptable level of cleanup.
 
  In connection with acquisitions accounted for using the purchase method of
accounting, the Automotive Divisions record, to the extent appropriate,
accruals for the costs of closing duplicate facilities, severing redundant
personnel and integrating the acquired business into existing operations of
the Automotive Divisions. Significant accruals include plant shut-down and
realignment costs, and facility relocations, and aggregated $19.8 million and
$23.5 million at December 31, 1997 and 1996, respectively.
 
  Amounts expended totaled $4.4 million, $20.7 million and $39.1 million in
1997, 1996 and 1995, respectively. The spending related primarily to
downsizing and consolidating international facilities in Mexico, Venezuela,
Belgium and the United Kingdom totaling $7.4 million and $29.8 million in 1996
and 1995, respectively.

  Cooper's cash and indebtedness is managed on a worldwide basis from the
Cooper corporate office in Houston, Texas. The majority of the cash provided
by or used by a particular division, including the Automotive Divisions is
provided through this consolidated cash and debt management system. As a
result, the amount of cash or debt historically related to the Automotive
Divisions is not determinable. For purposes of the Automotive Divisions'
historical financial statements, identifiable debt was allocated to the
Automotive Divisions during each year with all of the Automotive Divisions'
positive or negative cash flows being treated as cash transferred to or from
Cooper. The specifically identifiable industrial revenue bonds (the "IRB") and
specifically identifiable international debt was assigned to the Automotive
Divisions. The Automotive Divisions also have international short-term
borrowing facilities under which $35.5 million and $6.1 million was
outstanding at December 31, 1997 and 1996, respectively. In January 1998,
$23.0 million of the December 31, 1997 international short-term borrowings
amount was repaid.
 
  The industrial revenue bond principal is payable at maturity in 2019. The
future net minimum lease payments under capital leases and obligations under
noncancelable operating leases are not significant.
 
  For purposes of the Automotive Divisions' historical financial statements,
interest expense has been computed using the actual interest rate with respect
to the IRB and international short-term borrowings. Total interest related to
long-term debt and short-term debt paid during 1997, 1996 and 1995 was $1.1
million, $.8 million and $1.4 million, respectively.

NOTE 10: COOPER STOCK OPTIONS AND EMPLOYEE STOCK PURCHASE PLAN
 
  Under Cooper stock option plans, key employees of the Automotive Divisions
were granted options to purchase Cooper Common stock at no less than 100% of
the market price on the date the option is granted. Options generally become
exercisable ratably over a three-year period commencing one year from the date
of grant and have a maximum term of ten years. The plans also provide for the
granting of performance-based stock awards to certain key executives.
 
  Participants in the Cooper Employee Stock Purchase Plan receive an option to
purchase Cooper Common stock at a price that is the lesser of 90% of the
market value on the offering date or 100% of the market value on the purchase
date. On September 8, 1997, a total of 169,878 shares were sold to employees
of the Automotive Divisions at $35.33 per share. At December 31, 1997,
subscriptions from employees of the Automotive Divisions for the purchase of
220,860 shares of Cooper Common stock were outstanding at $45.68 per share or,
if lower, the average market price on September 10, 1999, which is the
purchase date.
 
  Cooper follows the intrinsic value method of accounting for stock options
and performance-based stock awards as prescribed by Accounting Principles
Board Opinion No. 25, Accounting for Stock Issued to Employees, and related
interpretations. Accordingly, no compensation expense is recognized in the
Automotive Divisions' combined income statements under Cooper's stock option
plans or Employee Stock Purchase Plan.

  U.S. income taxes have not been provided on $83.0 million of cumulative
undistributed earnings of certain non-U.S. subsidiaries at December 31, 1997.
The Automotive Divisions intend to indefinitely reinvest these earnings in
operations outside the United States.
 
NOTE 12: PENSION PLANS
 
  As part of Cooper, employees of the Automotive Divisions participate in
numerous pension plans covering substantially all domestic employees and
pension and similar arrangements in accordance with local customs covering
employees at foreign locations. The assets of the various domestic and foreign
plans are maintained in various trusts and consist primarily of equity and
fixed-income securities. Funding policies range from five to thirty years.
Pension benefits for salaried employees are generally based upon career
earnings. Benefits for hourly employees are generally based on a dollar unit,
multiplied by years of service. The amount of expense and the funded status
with respect to the defined benefit pension plans of the Automotive Divisions,
exclusive of the Cooper Salaried Employee Benefit Plan, is set forth in the
table below. In addition, most U.S. salaried employees of the Automotive
Divisions participate in the Cooper Salaried Employee Benefit Plan. The amount
of expense allocated to the Automotive Divisions for this plan was $.7
million, $1.7 million and $2.9 million for the years ended December 31, 1997,
1996 and 1995, respectively. During 1997, 1996 and 1995, the Automotive
Divisions' expense with respect to domestic and foreign defined contribution
plans (primarily related to various groups of hourly employees) amounted to
$5.4 million, $4.4 million and $4.0 million, respectively. The Automotive
Divisions' aggregate pension expense amounted to $13.8 million, $14.3 million
and $14.9 million during 1997, 1996 and 1995, respectively.

NOTE 13: POSTRETIREMENT BENEFITS OTHER THAN PENSIONS
 
  As part of Cooper, benefits provided to employees of the Automotive
Divisions under various postretirement plans other than pensions, all of which
are unfunded, include retiree medical care, dental care, prescriptions and
life insurance, with medical care accounting for approximately 90% of the
total. While the Automotive Divisions have numerous plans, primarily resulting
from extensive acquisition activity, the vast majority of the annual expense
is related to employees who are already retired. In fact, as a result of
actions taken starting in 1989, virtually no active salaried employees
continue to earn retiree medical benefits, and the number of active hourly
employees earning such benefits has been greatly diminished. Additionally, the
Automotive Divisions continue to amend their various plans to provide for
appropriate levels of cost sharing and other cost-control measures.

NOTE 14: COOPER EMPLOYEE SAVINGS AND EMPLOYEE STOCK OWNERSHIP PLANS
 
  All full-time domestic employees of the Automotive Divisions, except for
certain bargaining unit employees, are eligible to participate in the Cooper
Savings Plan ("CO-SAV"). Under the terms of the Plan, employee savings
deferrals are partially matched with contributions of Cooper Common stock
consisting of either an allocation of shares in Cooper's Employee Stock
Ownership Plan ("ESOP") or new shares issued to the ESOP.
 
  The Automotive Divisions' compensation expense with respect to the CO-SAV
plan and the ESOP was $5.8 million, $6.9 million and $6.6 million in 1997,
1996 and 1995, respectively.
 
NOTE 15: RELATED PARTY TRANSACTIONS
 
  For purposes of the combined financial statements, the intercompany account
between the Automotive Divisions and Cooper has been included as an element of
the Automotive Divisions' net assets. All free cash flows and cash
requirements of the Automotive Divisions are considered to be transferred to
or provided by Cooper and are included in this intercompany account.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The Automotive Divisions sell on third party terms small amounts of
Automotive Divisions' products to Cooper. The amounts involved are
insignificant to the Automotive Divisions.
 
NOTE 16: DOMESTIC AND INTERNATIONAL OPERATIONS
 
  The Automotive Divisions operate in a single business segment, Automotive
Products. The Automotive Divisions manufacture and distribute spark plugs,
wiper blades, lamps, brake friction materials and other products for use by
the automotive aftermarket and in automobile assemblies. In addition, the
Automotive Divisions manufacture and distribute suspension, steering driveline
and brake system components and material for the automotive aftermarket. No
single customer accounted for 10% or more of combined revenues in 1997, 1996
or 1995.
 
  Transfers between domestic and international operations, principally
inventory transfers, are designed to charge the receiving organization at
third-party arms-length prices that are generally sufficient to recover
manufacturing costs and provide a reasonable return. Export sales to
unaffiliated customers included in domestic sales were $113.3 million, $90.7
million and $85.2 million in 1997, 1996 and 1995, respectively. Of total
export sales, approximately 18% in 1997, 25% in 1996 and 23% in 1995 were to
Asia, Africa, Australia and the Middle East; 39% in 1997, 34% in 1996 and 35%
in 1995 were to Canada and Europe; 43% in 1997, 41% in 1996 and 42% in 1995
were to Latin America.

NOTE 17: OFF-BALANCE-SHEET RISK, CONCENTRATIONS OF CREDIT RISK AND FAIR VALUE
         OF FINANCIAL INSTRUMENTS, INCLUDING DERIVATIVES
 
  As a result of having sales and purchases and other transactions denominated
in currencies other than the functional currencies used by the Automotive
Divisions' businesses, the Automotive Divisions are exposed to the effect of
foreign exchange rate fluctuations on their cash flows and earnings. To the
extent possible, the Automotive Divisions utilize natural hedges to minimize
the effect on cash flows of fluctuating foreign currencies. When natural
hedges are not sufficient, it is the Automotive Divisions' policy to enter
into forward foreign exchange contracts to hedge all significant transactions
for periods consistent with the terms of the underlying transactions. The
Automotive Divisions do not engage in speculative transactions. While forward
contracts affect the Automotive Divisions' results of operations, they do so
only in connection with the underlying transactions. Gains and losses on these
contracts offset losses and gains on the transactions being hedged. The volume
of forward activity engaged in by the Automotive Divisions from year to year
fluctuates in proportion to the level of worldwide cross-border transactions,
and contracts generally have maturities that do not exceed one year. The table
below summarizes, by currency, the contractual amounts of the Automotive
Divisions' forward exchange contracts at December 31, 1997 and 1996.

  In the normal course of business, the Automotive Divisions have letters of
credit, performance bonds and other guarantees that are not reflected in the
combined balance sheets. In the past, no significant claims have been made
against these financial instruments. Management believes the likelihood of
performance under these instruments is minimal and expects no material losses
to occur in connection with these instruments. The Automotive Divisions' other
off-balance-sheet risks are not material.
 
 Concentrations of Credit Risk
 
  The Automotive Divisions grant credit to their customers, which are
primarily in the automotive industry. Credit risk with respect to trade
receivables is generally diversified due to the large number of entities
comprising the Automotive Divisions' customer base and their dispersion across
many different countries. The Automotive Divisions perform periodic credit
evaluations of their customers and generally do not require collateral.
 
  During the first quarter of 1998, a large customer of the Automotive
Divisions filed for reorganization under Chapter 11 of the U.S. Bankruptcy
Code. The Automotive Divisions had receivables from the customer of
approximately $12.5 million at the time of the filing and accrued a $12.5
million allowance for doubtful accounts in the December 31, 1997 combined
income statement.
 
 Fair Value of Financial Instruments
 
  The Automotive Divisions' financial instruments consist primarily of cash
and cash equivalents, trade receivables, trade payables, debt instruments and
foreign currency forward contracts. The book values of cash and cash
equivalents, trade receivables and trade payables are considered to be
representative of their respective
 
                                     I-29
<PAGE>
 
fair values. The Automotive Divisions had approximately $39.1 million and
$13.2 million of debt instruments at December 31, 1997 and 1996, respectively.
The book value of these instruments was approximately equal to fair value at
December 31, 1997 and 1996. Based on year-end exchange rates and the various
maturity dates of the foreign currency forward contracts, the Automotive
Divisions estimate that the contract value is representative of the fair value
of these items at December 31, 1997 and 1996.

               NOTES TO UNAUDITED COMBINED FINANCIAL STATEMENTS
 
NOTE 1. ACCOUNTING POLICIES
 
  Basis of Presentation--The accompanying unaudited condensed consolidated
financial statements have been prepared in accordance with United States
generally accepted accounting principles (US GAAP) for interim financial
information and with instructions to Form 10-Q and Article 10 of Regulation S-
X. Accordingly, they do not include all information and footnotes required by
generally accepted accounting principles for complete financial statements. In
the opinion of management, all adjustments (consisting of normal recurring
accruals) considered necessary for the fair presentation have been included.
Operating results for the nine-month period ended September 30, 1998 are not
necessarily indicative of the results that may be expected for the year ended
December 31, 1998. For further information, refer to the consolidated
financial statements and footnotes thereto included in this document for the
year ended December 31, 1997.
 
  Recently Issued Accounting Standards--In June 1998, the Financial Accounting
Standards Board issued Statement of Financial Accounting Standards No. 133,
Accounting for Derivative Financial Instruments and Hedging Activities ("SFAS
No. 133"). SFAS No. 133 requires that all derivatives be recognized as assets
and liabilities and measured at fair value. The accounting for changes in the
fair value of a derivative depends on the intended use of the derivative and
the resulting designation. The SFAS is effective for fiscal years beginning
after June 15, 1999 and early adoption is permitted. The Automotive Divisions
are currently evaluating the effects of the new standard. The Automotive
Divisions do not anticipate that the new standard will have an impact on net
income. However, the new standard requirement to mark to market certain of the
Automotive Divisions' combined financial instruments utilized to hedge
currency and commodity price risks will result in fluctuations in the fair
value being included as a component of net assets, net of tax. Due to the
Automotive Divisions' policies regarding financial instruments, it is not
likely that the adoption of the new standard will have a material effect on
the Automotive Divisions' Combined Balance Sheets.
 
NOTE 2. DIVESTITURES
 
  Effective March 28, 1998, the Moog Division completed the exchange of its
automotive temperature control business for the brake products business of
Standard Motor Products. In February 1998, the Moog Division completed the
sale of its constant velocity joint remanufacturing business. For accounting
purposes, the exchange transaction is recorded as the sale of the temperature
control business and the purchase of the Standard Motor Products' brake
business. The fair market value of the temperature control business assets was
equal to the net book value of the brake business assets after the write-down
of the temperature control business assets made in the second quarter of 1997.
The acquisition cost of the brake business assets was approximately $79
million, based on the actual book value of certain assets at the acquisition
date. The constant velocity joint remanufacturing business was sold for
approximately $4 million.
 
NOTE 3. NONRECURRING INCOME AND EXPENSES
 
  During the second quarter of 1997 the Automotive Divisions incurred a charge
of $33.8 million ($20.6 million after income taxes) for actions management
committed to during the quarter after concluding an evaluation of certain
sales, marketing and distribution activities and information systems relating
to year 2000 compliance efforts. The charge included adjustments to the
carrying value of assets of $27.6 million and accruals for continuing
obligations for replaced systems and facility consolidations of $6.2 million.
 
  The Automotive Divisions began a consolidation of certain sales, marketing
and distribution activities in the second quarter of 1997. Adjustments to the
carrying value of assets and accruals were recorded for projects committed to
by management. Severance and certain other costs are not expensed until the
affected employees are notified even though management has committed to the
projects. During the third quarter, the Automotive Divisions incurred charges
of $9.6 million for additional consolidations, including severance on certain
projects accrued for in the second quarter of 1997. The remaining committed
but unannounced consolidations are not expected to result in significant
additional expenses.

         NOTES TO UNAUDITED COMBINED FINANCIAL STATEMENTS--(CONCLUDED)
 
 
  During the second quarter of 1997, the Automotive Divisions also completed
their initial analysis of the impact of existing system capabilities to
function at the turn of the century. The Moog Division is implementing new
enterprise systems and the Cooper Automotive Division is revising or upgrading
existing software. Where possible, businesses have abandoned home-grown or
highly customized applications with purchased, year 2000 compliant
replacements or upgrades. In some situations, operations within a business
abandoned existing software and migrated to consolidated hardware and software
that is year 2000 compliant. The Automotive Divisions recorded a $11.6 million
charge in the second quarter of 1997 related to the adjustment in the carrying
value of abandoned hardware and software. While depreciation is reduced by the
effect of the write-down, depreciation of new systems, as well as expenses
related to revising current software to be year 2000 compliant and
implementation of new systems, are likely to exceed the reduction in
depreciation in most future periods.

                                  THE COMPANY
 
  Federal-Mogul is a leading global manufacturer and distributor of a broad
range of vehicular components for automobiles and light trucks, heavy duty
trucks, farm and construction vehicles and industrial products. Such
components include powertrain systems components (primarily bearings, rings
and pistons), sealing system components (dynamic seals and gaskets) and
general products (primarily friction products, sintered products, camshafts
and systems protection products). Federal-Mogul markets its products to many
of the world's major original equipment ("OE") manufacturers. Federal-Mogul
also manufactures and supplies its products and related parts to the
aftermarket relating to each of these categories of equipment.
 
  Founded in 1899, Federal-Mogul traditionally focused on the manufacture and
distribution of engine bearings and sealing systems. From 1990 through 1996,
Federal-Mogul pursued a strategy of opening retail auto stores in various
domestic and international locations. These geographically-dispersed stores
proved burdensome to manage and resulted in substantial operating losses. In
the fourth quarter of 1996, Federal-Mogul initiated a change of management,
following which the Company initiated a significant restructuring program
designed to refocus the Company on its core competency of manufacturing. As
part of its restructuring, Federal-Mogul closed or sold substantially all of
its retail operations. Federal-Mogul also began to pursue a growth strategy of
acquiring complementary manufacturing companies that enhance the Company's
product base, expand its global manufacturing operations and provide
opportunities to capitalize on the Company's aftermarket distribution network
and technological resources.
 
  In connection with its growth strategy, on March 6, 1998 Federal-Mogul
acquired T&N plc ("T&N"), a U.K. based supplier of engine and transmission
products, for total consideration of approximately (Pounds)1.46 billion ($2.41
billion, converted at a blended exchange rate of 1.6510 U.S. dollars to 1
pound sterling). T&N manufactures and supplies high technology engineered
automotive components and industrial materials including pistons, friction
products, bearings, systems protection, camshafts and sealing products. On
February 24, 1998, Federal-Mogul acquired Fel-Pro, Incorporated and certain
affiliated entities ("Fel-Pro"), a privately-owned automotive parts
manufacturer, for total consideration of approximately $717 million. Fel-Pro
is a premier gasket manufacturer for the North American aftermarket and OE
heavy duty market.
 
  Federal-Mogul operates facilities at over 240 manufacturing locations in 24
countries. On a pro forma basis (giving effect to the acquisitions of T&N and
Fel-Pro and the disposition of T&N thinwall and drywall and dry bearings
(polymer bearings) operations ("T&N Bearings Business") as if they had
occurred on January 1, 1997), Federal-Mogul's total sales for 1997 were $4.8
billion.
 
  Federal-Mogul is a Michigan corporation with its principal executive offices
located at 26555 Northwestern Highway, Southfield, Michigan 48034. The
telephone number of those offices is (248) 354-7700.

  The ratio of earnings to fixed charges has been computed by dividing
earnings by fixed charges. The ratio of earnings to combined fixed charges and
preferred stock dividends has been computed by dividing earnings by the sum of
fixed charges and preferred stock dividend requirements. Earnings consist of
income before income taxes plus fixed charges excluding capitalized interest.
Fixed charges consist of interest on all indebtedness, amortization of debt
issuance costs and the portion of rental expense representative of interest.
 
                                USE OF PROCEEDS
 
  Unless otherwise indicated in the accompanying Prospectus Supplement, the
net proceeds received by Federal-Mogul from the sale of the Securities offered
hereby are expected to be used for general corporate purposes. Any specific
allocation of the proceeds to a particular purpose that has been made at the
date of any Prospectus Supplement will be described therein. Federal-Mogul
will not receive any proceeds from the sale of shares of Common Stock by any
Selling Shareholder.
 
                        DESCRIPTION OF DEBT SECURITIES
 
  The Debt Securities offered hereby, consisting of notes, debentures and
other evidences of indebtedness, are to be issued in one or more series
constituting either senior Debt Securities ("Senior Debt Securities") or
subordinated Debt Securities ("Subordinated Debt Securities"). Unless
otherwise specified in the applicable Prospectus Supplement, the Debt
Securities will be issued pursuant to indentures described below (as
applicable, the "Senior Indenture" or the "Subordinated Indenture," each, an
"Indenture" and, together, the "Indentures"), in each case between Federal-
Mogul and the trustee identified therein (the "Trustee"), the forms of which
have been filed as exhibits to the Registration Statement of which this
Prospectus forms a part. Except for the subordination provisions of the
Subordinated Indenture, for which there are no counterparts in the Senior
Indenture, the provisions of the Subordinated Indenture are substantially
identical in substance to the provisions of the Senior Indenture that bear the
same section numbers.
 
                                       4
<PAGE>
 
  The statements herein relating to the Debt Securities and the following
summaries of certain general provisions of the Indentures do not purport to be
complete and are subject to, and are qualified in their entirety by reference
to, all the provisions of the Indentures (as they may be amended or
supplemented from time to time), including the definitions therein of certain
terms capitalized in this Prospectus. All article and section references
appearing herein are to articles and sections of the applicable Indenture and
whenever particular Sections or defined terms of the Indentures (as they may
be amended or supplemented from time to time) are referred to herein or in a
Prospectus Supplement, such Sections or defined terms are incorporated herein
or therein by reference.
 
GENERAL
 
  The Debt Securities will be unsecured obligations of Federal-Mogul. The
Indentures do not limit the aggregate amount of Debt Securities which may be
issued thereunder, nor do they limit the incurrence or issuance of other
secured or unsecured debt of Federal-Mogul. The Debt Securities issued under
the Senior Indenture will be unsecured and will rank pari passu with all other
unsecured and unsubordinated obligations of Federal-Mogul. The Debt Securities
issued under the Subordinated Indenture will be subordinate and junior in
right of payment, to the extent and in the manner set forth in the
Subordinated Indenture, to all Senior Indebtedness of Federal-Mogul. See "--
Subordination under the Subordinated Indenture."
 
  Reference is made to the applicable Prospectus Supplement which will
accompany this Prospectus for a description of the specific series of Debt
Securities being offered thereby, including, but not limited to, the
following: (1) the title of such Debt Securities, including whether the Debt
Securities are Senior Debt Securities or Subordinated Debt Securities and
whether such Debt Securities will be issued under the Senior Indenture, the
Subordinated Indenture or other indenture set forth in the Prospectus
Supplement; (2) any limit upon the aggregate principal amount of such Debt
Securities; (3) the date or dates on which the principal of and premium, if
any, on such Debt Securities is payable or the method of determining such date

Debt Securities will bear interest, if any, or the method of calculating such
rate or rates of interest, the date or dates from such interest will accrue or
the method by which such date or dates will be determined, the date or dates
on which interest, if any, will be payable and the record date or dates
therefor; (5) the place or places where principal of, premium, if any, and
interest, if any, on such Debt Securities will be payable; (6) the right, if
any, of Federal-Mogul to defer payment of interest on Debt Securities and the
maximum length of any such deferral period; (7) the period or periods within
which, the price or prices at which, the currency or currencies (including
currency unit or units) in which, and the other terms and conditions upon
which, such Debt Securities may be redeemed or otherwise purchased, in whole
or in part, at the option of Federal-Mogul; (8) the obligation, if any, and
the limitations, if any, on Federal-Mogul to redeem or purchase such Debt
Securities pursuant to any sinking fund or analogous provisions or upon the
happening of a specified event or at the option of a Holder thereof or at
Federal-Mogul's option or otherwise, or to apply any purchases of such Debt
Securities to any such redemption, and, if any, the period or periods within

receive payments in respect of such Debt Securities in a currency or currency
unit other than that in which such Debt Securities are stated to be payable;

amount of such Debt Securities which will be payable upon declaration of the
acceleration of the maturity thereof or the method by which such portion shall
be determined; (12) the person to whom any interest on any such Debt Security
shall be payable if other than the person in whose name such Debt Security is
registered on the applicable record date; (13) any addition to, or
modification or deletion of, any Event of Default or any covenant of Federal-
Mogul specified in the Indenture with respect to such Debt Securities; (14)
the
 
                                       5
<PAGE>
 
application, if any, of such means of defeasance or covenant defeasance as may
be specified for such Debt Securities; (15) whether such Debt Securities are
to be issued in whole or in part in the form of one or more temporary or
permanent global securities and, if so, the identity of the depositary for
such global security or securities; (16) whether the Debt Securities of the
series are convertible into Common Stock or Preferred Stock, and, if so, the
class or series of capital stock of Federal-Mogul into which such Debt
Securities are convertible and the terms and conditions upon which such

such Debt Securities. Unless otherwise specified in the applicable Prospectus
Supplement, the Debt Securities will not be listed on any securities exchange.
(Section 3.1.)
 
  Unless otherwise specified in the applicable Prospectus Supplement, Debt
Securities will be issued in fully-registered form without coupons. Where Debt
Securities of any series are issued in bearer form, the special restrictions
and considerations, including special offering restrictions and special United
States Federal income tax considerations, applicable to any such Debt
Securities and to payment on and transfer and exchange of such Debt Securities
will be described in the applicable Prospectus Supplement. Bearer Debt
Securities will be transferable by delivery. (Section 3.5.)
 
  Debt Securities may be sold at a substantial discount below their stated
principal amount, bearing no interest or interest at a rate which at the time
of issuance is below market rates. Certain United States Federal income tax
consequences and special considerations applicable to any such Debt
Securities, or to Debt Securities issued at par that are treated as having
been issued at a discount, will be described in the applicable Prospectus
Supplement.
 
  If the purchase price of any of the Debt Securities is payable in one or
more foreign currencies or currency units or if any Debt Securities are
denominated in one or more foreign currencies or currency units or if the
principal of, premium, if any, or interest, if any, on any Debt Securities is
payable in one or more foreign currencies or currency units, or by reference
to commodity prices, equity indices or other factors, the restrictions,
elections, certain United States Federal income tax considerations, specific
terms and other information with respect to such issue of Debt Securities and
such foreign currency or currency units or commodity prices, equity indices or
other factors will be set forth in the applicable Prospectus Supplement. In
general, holders of such series of Debt Securities may receive a principal
amount on any principal payment date, or a payment of premium, if any, on any
premium payment date or a payment of interest on any interest payment date,
that is greater than or less than the amount of principal, premium, if any, or
interest, if any, otherwise payable on such dates, depending on the value on
such dates of the applicable currency, commodity, equity index or other
factor.
 
GUARANTEES
 
  Each Prospectus Supplement will describe, as to the Debt Securities to which
it relates, any guarantees for the benefit of such Debt Securities, which may
be granted by one or more of the following direct and indirect subsidiaries of
the Company: Federal-Mogul Dutch Holdings Inc., Federal-Mogul Global Inc.,
Federal-Mogul U.K. Holdings Inc., Carter Automotive Company, Federal Mogul
Venture Corporation, Federal-Mogul World Wide, Inc., Federal-Mogul Global
Properties, Inc., Felt Products Mfg. Co., Fel-Pro Management Co. and Fel-Pro
Chemical Products, L.P. The first three named Guarantors are holding companies
whose sole assets are stock of subsidiaries or intercompany debt. The net book
value of each of the other Guarantors is less than $10 million per Guarantor,
except for Fel-Pro Chemical Products, L.P., which had a net book value of
approximately $40 million at March 31, 1998 and is in the process of being
sold. The Guarantees are thus not expected to be of significant value to the
holders of the Debt Securities, and Federal-Mogul does not believe that
separate financial information or other information in respect of the
Guarantors would be material to purchasers of Debt Securities. Each Prospectus
Supplement will specify which of these entities will provide guarantees in
connection with any series of notes. Each such Prospectus Supplement will also
describe any provisions regarding release or addition of guarantors of
obligations under such Debt Securities.
 
PAYMENT, REGISTRATION, TRANSFER AND EXCHANGE
 
  Unless otherwise provided in the applicable Prospectus Supplement, payments
in respect of the Debt Securities will be made in the designated currency at
the office or agency of Federal-Mogul maintained for that purpose as Federal-
Mogul may designate from time to time, except that, at the option of Federal-
Mogul, interest
 
                                       6
<PAGE>
 
payments, if any, on Debt Securities in registered form may be made (i) by
check mailed to the address of the person entitled thereto as specified in the
Register or (ii) at Federal-Mogul's expense, by wire transfer to an account
maintained by the person entitled thereto as specified in the Register.
(Sections 3.7(a) and 9.2.) Unless otherwise indicated in the applicable
Prospectus Supplement, payment of any installment of interest on Debt
Securities in registered form will be made to the person in whose name such
Debt Security is registered at the close of business on the regular record
date for such interest. (Section 3.7(a).)
 
  Payment in respect of Debt Securities in bearer form will be made in the
currency and in the manner designated in the Prospectus Supplement, subject to
any applicable laws and regulations, at such paying agencies outside the
United States as Federal-Mogul may appoint from time to time. The paying
agents outside the United States initially appointed by Federal-Mogul for a
series of Debt Securities will be named in the Prospectus Supplement. Federal-
Mogul may at any time designate additional paying agents or rescind the
designation of any paying agents, except that, if Debt Securities of a series
are issuable as Registered Securities, Federal-Mogul will be required to
maintain at least one paying agent in each Place of Payment for such series
and, if Debt Securities of a series are issuable as Bearer Securities,
Federal-Mogul will be required to maintain a paying agent in a Place of
Payment outside the United States where Debt Securities of such series and any
coupons appertaining thereto may be presented and surrendered for payment.
(Section 9.2.)
 
  Unless otherwise provided in the applicable Prospectus Supplement, Debt
Securities in registered form will be transferable or exchangeable at the
agency of Federal-Mogul maintained for such purpose as designated by Federal-
Mogul from time to time. (Sections 3.5 and 9.2.) Debt Securities may be
transferred or exchanged without service charge, other than any tax or other
governmental charge imposed in connection therewith. (Section 3.5.)
 
GLOBAL DEBT SECURITIES
 
  Unless otherwise specified in the applicable Prospectus Supplement, the Debt
Securities of a series may be issued in whole or in part in the form of one or
more fully registered global securities (a "Registered Global Security") that
will be deposited with a depositary (the "Depositary") or with a nominee for
the Depositary identified in the applicable Prospectus Supplement. In such a
case, one or more Registered Global Securities will be issued in a
denomination or aggregate denominations equal to the portion of the aggregate
principal amount of outstanding Debt Securities of the series to be
represented by such Registered Global Security or Securities. (Section 3.3.)
Unless and until it is exchanged in whole or in part for Debt Securities in
definitive certificated form, a Registered Global Security may not be
transferred except as a whole by the Depositary for such Registered Global
Security to a nominee of such Depositary or by a nominee of such Depositary to
such Depositary or another nominee of such Depositary or by such Depositary or
any such nominee to a successor Depositary for such series or a nominee of
such successor Depositary and except in the circumstances described in the
applicable Prospectus Supplement. (Section 3.5.)
 
  The specific terms of the depositary arrangement with respect to any portion
of a series of Debt Securities to be represented by a Registered Global
Security will be described in the applicable Prospectus Supplement. Unless
otherwise specified in the applicable Prospectus Supplement, Federal-Mogul
expects that the following provisions will apply to such depositary
arrangements.
 
  Ownership of beneficial interests in a Registered Global Security will be
limited to participants or persons that may hold interests through
participants (as such term is defined below). Upon the issuance of any
Registered Global Security, and the deposit of such Registered Global Security
with or on behalf of the Depositary for such Registered Global Security, the
Depositary will credit, on its book-entry registration and transfer system,
the respective principal amounts of the Debt Securities represented by such
Registered Global Security to the accounts of institutions ("participants")
that have accounts with the Depositary or its nominee. The accounts to be
credited will be designated by the underwriters or agents engaging in the
distribution of such Debt Securities or by Federal-Mogul, if such Debt
Securities are offered and sold directly by Federal-Mogul. Ownership of
beneficial interests by participants in such Registered Global Security will
be shown on, and the transfer of such
 
                                       7
<PAGE>
 
beneficial interests will be effected only through, records maintained by the
Depositary for such Registered Global Security or by its nominee. Ownership of
beneficial interests in such Registered Global Security by persons that hold
through participants will be shown on, and the transfer of such beneficial
interests within such participants will be effected only through, records
maintained by such participants. The laws of some jurisdictions require that
certain purchasers of securities take physical delivery of such securities in
certificated form. The foregoing limitations and such laws may impair the
ability to transfer beneficial interests in such Registered Global Security.
 
  So long as the Depositary for a Registered Global Security, or its nominee,
is the registered owner of such Registered Global Security, such Depositary or
such nominee, as the case may be, will be considered the sole owner or holder
of the Debt Securities represented by such Registered Global Security for all
purposes under the applicable Indenture. Unless otherwise specified in the
applicable Prospectus Supplement and except as specified below, owners of
beneficial interests in such Registered Global Security will not be entitled
to have Debt Securities of the series represented by such Registered Global
Security registered in their names, will not receive or be entitled to receive
physical delivery of Debt Securities of such series in certificated form and
will not be considered the holders thereof for any purposes under the relevant
Indenture. (Section 3.8.) Accordingly, each person owning a beneficial
interest in such Registered Global Security must rely on the procedures of the
Depositary and, if such person is not a participant, on the procedures of the
participant through which such person owns its interest, to exercise any
rights of a holder under the relevant Indenture. The Depositary may grant
proxies and otherwise authorize participants to give or take any request,
demand, authorization, direction, notice, consent, waiver or other action
which a holder is entitled to give or take under the relevant Indenture.
Federal-Mogul understands that, under existing industry practices, if Federal-
Mogul requests any action of holders or if any owner of a beneficial interest
in such Registered Global Security desires to give any notice or take any
action which a holder is entitled to give or take under the relevant
Indenture, the Depositary would authorize the participants to give such notice
or take such action, and such participants would authorize beneficial owners
owning through such participants to give such notice or take such action or
would otherwise act upon the instructions of beneficial owners owning through
them.
 
  Unless otherwise specified in the applicable Prospectus Supplement, payments
with respect to principal, premium, if any, and interest, if any, on Debt
Securities represented by a Registered Global Security registered in the name
of a Depositary or its nominee will be made to such Depositary or its nominee,
as the case may be, as the registered owner of such Registered Global
Security. (Section 3.8.)
 
  Federal-Mogul expects that the Depositary for any Debt Securities
represented by a Registered Global Security, upon receipt of any payment of
principal, premium or interest, will immediately credit participants' accounts
with payments in amounts proportionate to their respective beneficial
interests in the principal amount of such Registered Global Security as shown
on the records of such Depositary. Federal-Mogul also expects that payments by
participants to owners of beneficial interests in such Registered Global
Security held through such participants will be governed by standing
instructions and customary practices, as is now the case with the securities
held for the accounts of customers registered in "street names," and will be
the responsibility of such participants. None of Federal-Mogul, the respective
Trustees or any agent of Federal-Mogul or the respective Trustees shall have
any responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests of a Registered
Global Security, or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests. (Section 3.8.)
 
  Unless otherwise specified in the applicable Prospectus Supplement, if the
Depositary for any Debt Securities represented by a Registered Global Security
is at any time unwilling or unable to continue as Depositary or ceases to be a
clearing agency registered under the Exchange Act and any other applicable
statute or regulation and a duly registered successor Depositary is not
appointed by Federal-Mogul within 90 days, Federal-Mogul will issue such Debt
Securities in definitive certificated form in exchange for such Registered
Global Security. In addition, Federal-Mogul may at any time in its sole
discretion determine not to have any of the Debt Securities of a series
represented by one or more Registered Global Securities and, in such event,
will
 
                                       8
<PAGE>
 
issue Debt Securities of such series in definitive certificated form in
exchange for all of the Registered Global Security or Securities representing
such Debt Securities. (Section 3.5.)
 
  The Debt Securities of a series may also be issued in whole or in part in
the form of one or more bearer global securities (a "Bearer Global Security")
that will be deposited with a depositary, or with a nominee for such
depositary, identified in the applicable Prospectus Supplement. Any such
Bearer Global Security may be issued in temporary or permanent form. (Section
3.4.) The specific terms and procedures, including the specific terms of the
depositary arrangement, with respect to any portion of a series of Debt
Securities to be represented by one or more Bearer Global Securities will be
described in the applicable Prospectus Supplement.
 
CONSOLIDATION, MERGER OR SALE BY FEDERAL-MOGUL
 
  Unless otherwise specified in the applicable Prospectus Supplement, Federal-
Mogul shall not consolidate with or merge into any other corporation or
transfer or lease all or substantially all of its assets, unless: (i) the
corporation formed by such consolidation or into which Federal-Mogul is merged
or the corporation which acquires its assets is organized in the United
States; (ii) the corporation formed by such consolidation or into which
Federal-Mogul is merged or which acquires Federal-Mogul's assets expressly
assumes all of the obligations of Federal-Mogul under each Indenture; (iii)
immediately after giving effect to such transaction, no Default (as
hereinafter defined) or Event of Default exists; and (iv) if, as a result of
such transaction, properties or assets of Federal-Mogul would become subject
to an encumbrance which would not be permitted by the terms of any series of
Debt Securities, Federal-Mogul or the successor corporation, as the case may
be, shall take such steps as are necessary to secure such Debt Securities
equally and ratably with all indebtedness secured thereunder. Upon any such
consolidation, merger or sale, the successor corporation formed by such
consolidation, or into which Federal-Mogul is merged or to which such sale is
made, shall succeed to, and be substituted for Federal-Mogul under each
Indenture. (Section 7.1.)
 
EVENTS OF DEFAULT, NOTICE AND CERTAIN RIGHTS ON DEFAULT
 
  Each Indenture provides that, if an Event of Default specified therein
occurs with respect to the Debt Securities of any series and is continuing,
the Trustee for such series or the holders of at least 25% in aggregate
principal amount of all of the outstanding Debt Securities of that series, by
written notice to Federal-Mogul (and to the Trustee for such series, if notice
is given by such holders of Debt Securities), may declare the principal of
(or, if the Debt Securities of that series are Original Issue Discount
Securities or Indexed Securities, such portion of the original principal
amount specified in the Prospectus Supplement) and accrued interest, if any,
on all the Debt Securities of that series to be due and payable (provided,
with respect to any Debt Securities issued under the Subordinated Indenture,
that the payment of principal, premium, if any, and interest, if any, on such
Debt Securities shall remain subordinated to the extent provided in Article 12
of the Subordinated Indenture). (Section 5.2.)
 
  Unless otherwise specified in the applicable Prospectus Supplement, Events
of Default with respect to Debt Securities of any series are defined in each
Indenture as being: (a) default for 30 days in payment of any interest on any
Debt Security of that series or any coupon appertaining thereto or any
additional amount payable with respect to Debt Securities of such series as
specified in the applicable Prospectus Supplement when due and payable; (b)
default in payment of principal, or premium, if any, at maturity or on
redemption or otherwise, or in the making of a mandatory sinking fund payment
of any Debt Securities of that series when due; (c) default for 60 days after
notice to Federal-Mogul by the Trustee for such series, or to Federal-Mogul
and the Trustee for such series by the holders of at least 25% in aggregate
principal amount of the Debt Securities of such series then outstanding, in
the performance of any covenant with respect to the Debt Securities of that
series; (d) with respect to the Senior Indenture, default with respect to
other indebtedness of Federal-Mogul for borrowed money in an aggregate
principal amount of at least $25 million, which default shall constitute a
failure to pay any portion of the principal when due and payable after the
expiration of an applicable grace period with respect thereto or shall result
in an acceleration thereof and such acceleration is not rescinded or annulled
or such debt shall not be paid in full within 30 days after the written notice
thereof to Federal-Mogul by the Trustee or to Federal-Mogul
 
                                       9
<PAGE>
 
and the Trustee by the holders of 25% in aggregate principal amount of the
Debt Securities of such series then outstanding, provided that such Event of
Default will be remedied, cured or waived if such default under such other
agreement is remedied, cured or waived; and (e) certain events of bankruptcy,
insolvency or reorganization of Federal-Mogul. (Section 5.1.) The definition
of "Event of Default" in each Indenture specifically excludes a default under
a secured debt under which the obligee has recourse (exclusive of recourse for
ancillary matters such as environmental indemnities, misapplication of funds,
costs of enforcement, etc.) only to the collateral pledged for repayment, and
where the fair market value of such collateral does not exceed two percent of
Total Assets (as defined in the Indenture) at the time of the default. Events
of Default with respect to a specified series of Debt Securities may be added
to the Indenture and, if so added, will be described in the applicable
Prospectus Supplement. (Sections 3.1 and 5.1(7).)
 
  Each Indenture provides that the Trustee will, if it is known to a
Responsible Officer of the Trustee, within 90 days after the occurrence of a
Default with respect to the Debt Securities of any series, give to the holders
of the Debt Securities of that series notice of all Defaults known to it
unless such Default shall have been cured or waived; provided, that except in
the case of a Default in payment on the Debt Securities of that series, the
Trustee may withhold the notice if and so long as the board of directors, the
executive committee or a committee of its Responsible Officers in good faith
determines that withholding such notice is in the interests of the holders of
the Debt Securities of that series. (Section 6.6.) "Default" means any event
which is, or after notice or passage of time or both, would be, an Event of
Default. (Section 1.1.)
 
  Each Indenture provides that the holders of a majority in aggregate
principal amount of the Debt Securities of each series affected (with each
such series voting as a class) may, subject to certain limited conditions,
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee for such series, or exercising any trust or power
conferred on such Trustee. (Section 5.8.)
 
  Each Indenture includes a covenant that Federal-Mogul will file annually
with the Trustee a certificate as to Federal-Mogul's compliance with all
conditions and covenants of such Indenture. (Section 9.6.)
 
  The holders of a majority in aggregate principal amount of any series of
Debt Securities then outstanding by notice to the Trustee for such series may
waive, on behalf of the holders of all Debt Securities of such series, any
past Default or Event of Default with respect to that series and its
consequences except a Default or Event of Default in the payment of the
principal of, premium, if any, or interest, if any, on any Debt Security of
such series, or except in respect of an Event of Default resulting from the
breach of a covenant or provision of either Indenture which, pursuant to the
applicable Indenture, cannot be amended or modified without the consent of the
holders of each outstanding Debt Security of such series affected. (Section
5.7.)
 
OPTION TO DEFER INTEREST PAYMENTS
 
  If provided in the applicable Prospectus Supplement, Federal-Mogul shall
have the right at any time and from time to time during the term of the series
of Debt Securities to defer the payment of interest for such number of
consecutive interest payment periods as may be specified in the applicable
Prospectus Supplement (each, an "Extension Period"), subject to the terms,
conditions and covenants, if any, specified in such Prospectus Supplement,
provided that such Extension Period may not extend beyond the stated maturity
of the Debt Securities. Certain material United States Federal income tax
consequences and special considerations applicable to any such Debt Securities
will be described in the applicable Prospectus Supplement.
 
  Unless otherwise specified in the applicable Prospectus Supplement, at the
end of such Extension Period, Federal-Mogul shall pay all interest then
accrued and unpaid together with interest thereon compounded semiannually at
the rate specified for the Debt Securities to the extent permitted by
applicable law ("Compound Interest"); provided, that during any such Extension
Period, (a) Federal-Mogul shall not declare or pay dividends on, make
distributions with respect to, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of its capital stock (other than (i)
purchases or acquisitions of capital stock of Federal-Mogul in connection with
the satisfaction by Federal-Mogul of its obligations under any employee or
agent benefit plans
 
                                      10
<PAGE>
 
or the satisfaction by Federal-Mogul of its obligations pursuant to any
contract or security outstanding on the date of such event requiring Federal-
Mogul to purchase capital stock of Federal-Mogul, (ii) as a result of a
reclassification of Federal-Mogul's capital stock or the exchange or
conversion of one class or series of Federal-Mogul's capital stock for another
class or series of Federal-Mogul's capital stock, (iii) the purchase of
fractional interests in shares of Federal-Mogul's capital stock pursuant to
the conversion of exchange provisions of such capital stock or the security
being conversed or exchanged, (iv) dividends or distributions in capital stock
of Federal-Mogul (or rights to acquire capital stock) or repurchases or
redemptions of capital stock solely from the issuance or exchange of capital
stock or (v) redemptions or repurchases of any rights outstanding under a
shareholder rights plan), (b) Federal-Mogul shall not make any payment of
interest, principal or premium, if any, on or repay, repurchase or redeem any
debt securities issued by Federal-Mogul that rank junior to the Debt
Securities, and (c) Federal-Mogul shall not make any guarantee payments with
respect to the foregoing. Prior to the termination of any such Extension
Period, Federal-Mogul may further defer payments of interest by extending the
interest payment period; provided, however, that, such Extension Period,
including all such previous and further extensions, may not extend beyond the
maturity of the Debt Securities. Upon the termination of any Extension Period
and the payment of all amounts then due, Federal-Mogul may commence a new
Extension Period, subject to the terms set forth in this section. No interest
during an Extension Period, except at the end thereof, shall be due and
payable, but Federal-Mogul may prepay at any time all or any portion of the
interest accrued during an Extension Period. Federal-Mogul has no present
intention of exercising its right to defer payments of interest by extending
the interest payment period on the Debt Securities. Federal-Mogul shall give
the holders of the Debt Securities notice of its selection of such Extension
Period ten Business Days prior to the earlier of (i) the Interest Payment Date
or (ii) the date upon which Federal-Mogul is required to give notice to the
New York Stock Exchange (or other applicable self-regulatory organization) or
to holders of the Debt Securities of the record or payment date of such
related interest payment.
 
MODIFICATION OF THE INDENTURES
 
  Unless otherwise specified in the applicable Prospectus Supplement, each
Indenture contains provisions permitting Federal-Mogul and the Trustee to
enter into one or more supplemental indentures without the consent of the
holders of any of the Debt Securities in order (i) to evidence the succession
of another corporation to Federal-Mogul and the assumption of the covenants
and obligations of Federal-Mogul by a successor to Federal-Mogul; (ii) to add
to the covenants of Federal-Mogul or to surrender any right or power of
Federal-Mogul; (iii) to add additional Events of Default with respect to any
series of Debt Securities; (iv) to add or change any provisions to such extent
as necessary to facilitate the issuance of Debt Securities in bearer form or
to facilitate the issuance of Debt Securities in global form; (v) to add,
change or eliminate any provision affecting only Debt Securities not yet
issued; (vi) to secure the Debt Securities; (vii) to establish the form or
terms of Debt Securities; (viii) to evidence and provide for successor
Trustees; (ix) if allowed without penalty under applicable laws and
regulations, to permit payment in respect of Debt Securities in bearer form in
the United States; (x) to correct any defect or supplement any inconsistent
provisions or to make any other provisions with respect to matters or
questions arising under such Indenture, provided that such action does not
adversely affect the interests of the holders of Debt Securities of any
series; or (xi) to cure any ambiguity or correct any mistake. The Subordinated
Indenture also permits Federal-Mogul and the Trustee thereunder to enter into
such supplemental indentures to modify the subordination provisions contained
in the Subordinated Debenture except in a manner adverse to any outstanding
Debt Securities. (Section 8.1.)
 
  Unless otherwise specified in the applicable Prospectus Supplement, each
Indenture also contains provisions permitting Federal-Mogul and the Trustee,
with the consent of the holders of a majority in aggregate principal amount of
the outstanding Debt Securities affected by such supplemental indenture (with
the Debt Securities of each series voting as a class), to execute supplemental
indentures adding any provisions to or changing or eliminating any of the
provisions of such Indenture or any supplemental indenture or modifying the
rights of the holders of Debt Securities of such series, except that, without
the consent of the holder of each Debt Security so affected, no such
supplemental indenture may: (i) change the time for payment of principal or
premium, if any, or interest, if any, on any Debt Security; (ii) reduce the
principal of, or the rate of interest, or premium, if any,
 
                                      11
<PAGE>
 
on any Debt Security, or change the manner in which the amount of any of the
foregoing is determined; (iii) reduce the amount of premium, if any, payable
upon the redemption of any Debt Security; (iv) reduce the amount of principal
payable upon acceleration of the maturity of any Original Issue Discount
Security or Indexed Security; (v) impair the right to institute suit for the
enforcement of any payment on or with respect to any Debt Security; (vi)
reduce the percentage in principal amount of the outstanding Debt Securities
affected thereby, the consent of whose holders is required for modification or
amendment of such Indenture or for waiver of compliance with certain
provisions of the Indenture or for waiver of certain defaults; (viii) change
the obligation of Federal-Mogul to maintain an office or agency in the places
and for the purposes specified in such Indenture; (ix) modify the provisions
relating to the subordination of outstanding Debt Securities of any series in
a manner adverse to the holders thereof; or (x) modify the provisions relating
to waiver of certain defaults or any of the foregoing provisions. (Section
8.2.)
 
SUBORDINATION UNDER THE SUBORDINATED INDENTURE
 
  The Subordinated Indenture provides that any Subordinated Debt Securities
issued thereunder are subordinate and junior in right of payment to all Senior
Indebtedness to the extent provided in the Subordinated Indenture. (Section
12.1 of the Subordinated Indenture.) The Subordinated Indenture defines the
term "Senior Indebtedness" as: (i) all indebtedness of Federal-Mogul, whether
outstanding on the date of the Subordinated Indenture or thereafter created,
incurred or assumed, that is for money borrowed, or evidenced by a note or
similar instrument given in connection with the acquisition of any business,
properties or assets, including securities; (ii) any indebtedness of others of
the kinds described in the preceding clause (i) for the payment of which
Federal-Mogul is responsible or liable as guarantor or otherwise; and (iii)
amendments, renewals, extensions and refundings of any such indebtedness. The
Senior Indebtedness shall continue to be Senior Indebtedness and entitled to
the benefits of the subordination provisions irrespective of any amendment,
modification or waiver of any term of the Senior Indebtedness or extension or
renewal of the Senior Indebtedness. Senior Indebtedness does not include (A)
any indebtedness of Federal-Mogul to any of its subsidiaries, (B) indebtedness
incurred for the purchase of goods or materials or for services obtained in
the ordinary course of business, and (C) any indebtedness which by its terms
is expressly made pari passu with or subordinated to the Subordinated Debt
Securities. (Section 12.2 of the Subordinated Indenture.)
 
  If (i) Federal-Mogul defaults in the payment of any principal, or premium,
if any, or interest, if any, on any Senior Indebtedness when the same becomes
due and payable, whether at maturity or at a date fixed for prepayment or
declaration or otherwise or (ii) an event of default occurs with respect to
any Senior Indebtedness permitting the holders thereof to accelerate the
maturity thereof and written notice of such event of default (requesting that
payments on Subordinated Debt Securities cease) is given to Federal-Mogul by
the holders of Senior Indebtedness, then unless and until such default in
payment or event of default shall have been cured or waived or shall have
ceased to exist, no direct or indirect payment (in cash, property or
securities, by set-off or otherwise) shall be made or agreed to be made on
account of the Subordinated Debt Securities or interest thereon or in respect
of any repayment, redemption, retirement, purchase or other acquisition of
Subordinated Debt Securities. (Section 12.4 of the Subordinated Indenture.)
 
  In the event of (i) any insolvency, bankruptcy, receivership, liquidation,
reorganization, readjustment, composition or other similar proceeding relating
to Federal-Mogul, its creditors or its property, (ii) any proceeding for the
liquidation, dissolution or other winding-up of Federal-Mogul, voluntary or
involuntary, whether or not involving insolvency or bankruptcy proceedings,
(iii) any assignment by Federal-Mogul for the benefit of creditors, or (iv)
any other marshalling of the assets of Federal-Mogul, all Senior Indebtedness
(including, without limitation, interest accruing after the commencement of
any such proceeding, assignment or marshalling of assets) shall first be paid
in full before any payment or distribution, whether in cash, securities or
other property, shall be made by Federal-Mogul on account of Subordinated Debt
Securities. In any such event, any payment or distribution, whether in cash,
securities or other property (other than securities of Federal-Mogul or any
other corporation provided for by a plan of reorganization or readjustment,
the payment of which is subordinate, at least to the extent provided in the
subordination provisions of the Subordinated Indenture with
 
                                      12
<PAGE>
 
respect to the indebtedness evidenced by Subordinated Debt Securities, to the
payment of all Senior Indebtedness at the time outstanding and to any
securities issued in respect thereof under any such plan of reorganization or
readjustment), which would otherwise (but for the subordination provisions) be
payable or deliverable in respect of Subordinated Debt Securities (including
any such payment or distribution which may be payable or deliverable by reason
of the payment of any other indebtedness of Federal-Mogul being subordinated
to the payment of Subordinated Debt Securities) shall be paid or delivered
directly to the holders of Senior Indebtedness, or to their representative or
trustee, in accordance with the priorities then existing among such holders
until all Senior Indebtedness shall have been paid in full. (Section 12.3 of
the Subordinated Indenture.) No present or future holder of any Senior
Indebtedness shall be prejudiced in the right to enforce subordination of the
indebtedness evidenced by Subordinated Debt Securities by any act or failure
to act on the part of Federal-Mogul. (Section 12.9 of the Subordinated
Indenture.)
 
  Senior Indebtedness shall not be deemed to have been paid in full unless the
holders thereof shall have received cash, securities or other property equal
to the amount of such Senior Indebtedness then outstanding. After all Senior
Indebtedness has been paid in full and until the Subordinated Debt Securities
are paid in full, the holders of Subordinated Debt Securities shall be
subrogated to the rights of the holders of Senior Indebtedness to receive
distributions applicable to the Senior Indebtedness to the extent that
distributions otherwise payable to the holders of Subordinated Debt Securities
have been applied to the payment of Senior Indebtedness, and such payments or
distributions received by any holder of Subordinated Debt Securities, by
reason of such subrogation, of cash, securities or other property which
otherwise would be paid or distributed to the holders of Senior Indebtedness,
shall, as between Federal-Mogul and its creditors other than the holders of
Senior Indebtedness, on the one hand, and the holders of Subordinated Debt
Securities, on the other, be deemed to be a payment by Federal-Mogul on
account of Senior Indebtedness, and not on account of Subordinated Debt
Securities. (Section 12.7 of the Subordinated Indenture.)
 
  The Subordinated Indenture provides that the foregoing subordination
provisions, insofar as they relate to any particular issue of Subordinated
Debt Securities, may be changed prior to such issuance. Any such change would
be described in the applicable Prospectus Supplement relating to such
Subordinated Debt Securities.
 
DEFEASANCE AND COVENANT DEFEASANCE
 
  If indicated in the applicable Prospectus Supplement, Federal-Mogul may
elect either (i) to defease and be discharged from any and all obligations
with respect to the Debt Securities of or within any series (except as
otherwise provided in the relevant Indenture) ("defeasance") or (ii) to be
released from its obligations with respect to certain covenants applicable to
the Debt Securities of or within any series ("covenant defeasance"), upon the
deposit with the relevant Trustee (or other qualifying trustee), in trust for
such purpose, of money and/or Government Obligations which through the payment
of principal and interest in accordance with their terms will provide money in
an amount sufficient, without reinvestment, to pay the principal of and any
premium or interest on such Debt Securities to Maturity or redemption, as the
case may be, and any mandatory sinking fund or analogous payments thereon. As
a condition to defeasance or covenant defeasance, Federal-Mogul must deliver
to the Trustee an Opinion of Counsel to the effect that the Holders of such
Debt Securities will not recognize income, gain or loss for United States
Federal income tax purposes as a result of such defeasance or covenant
defeasance and will be subject to United States Federal income tax on the same
amounts and in the same manner and at the same times as would have been the
case if such deposit, defeasance and discharge had not occurred. Such Opinion
of Counsel, in the case of defeasance under clause (i) above, must refer to
and be based upon a ruling of the Internal Revenue Service or a change in
applicable Federal income tax law occurring after the date of the relevant
Indenture. (Article 4.) If indicated in the applicable Prospectus Supplement,
in addition to obligations of the United States or an agency or
instrumentality thereof, Government Obligations may include obligations of the
government or an agency or instrumentality of the government issuing the
currency or currency unit in which Debt Securities of such series are payable.
(Section 3.1.)
 
  In addition, with respect to the Subordinated Indenture, in order to be
discharged, no event or condition shall exist that, pursuant to certain
provisions described under "--Subordination under the Subordinated
 
                                      13
<PAGE>
 
Indenture" above, would prevent Federal-Mogul from making payments of
principal of (and premium, if any) and interest, if any, on Subordinated Debt
Securities at the date of the irrevocable deposit referred to above. (Section
4.6(i) of the Subordinated Indenture.)
 
  Federal-Mogul may exercise its defeasance option with respect to such Debt
Securities notwithstanding its prior exercise of its covenant defeasance
option. If Federal-Mogul exercises its defeasance option, payment of such Debt
Securities may not be accelerated because of an Event of Default. (Section
4.4.) If Federal-Mogul exercises its covenant defeasance option, payment of
such Debt Securities may not be accelerated by reason of a Default or an Event
of Default with respect to the covenants to which such covenant defeasance is
applicable. However, if such acceleration were to occur by reason of another
Event of Default, the realizable value at the acceleration date of the money
and Government Obligations in the defeasance trust could be less than the
principal and interest then due on such Debt Securities, in that the required
deposit in the defeasance trust is based upon scheduled cash flow rather than
market value, which will vary depending upon interest rates and other factors.
 
THE TRUSTEES
 
  Unless otherwise specified in the applicable Prospectus Supplement, The Bank
of New York will be the Trustee under the Senior Indenture and under the
Subordinated Indenture. Federal-Mogul may also maintain banking and other
commercial relationships with each of the Trustees and their affiliates in the
ordinary course of business.
 
                DESCRIPTION OF PREFERRED STOCK AND COMMON STOCK
 
  In general, the classes of authorized capital stock are afforded preferences
with respect to dividends and liquidation rights in the order listed above.
The Board of Directors of Federal-Mogul is empowered, without approval of the
shareholders, to cause the Preferred Stock to be issued in one or more series,
with the numbers of shares of each series and the rights, preferences and
limitations of each series to be determined by it including, without
limitation, the dividend rights, conversion rights, redemption rights and
liquidation preferences, if any, of any wholly unissued series of Preferred
Stock (or of the entire class of Preferred Stock if none of such shares have
been issued), the number of shares constituting each such series and the terms
and conditions of the issue thereof. The descriptions set forth below do not
purport to be complete and are qualified in their entirety by reference to the
Restated Articles of Incorporation.
 
  The Prospectus Supplement relating to an offering of Common Stock will
describe terms relevant thereto, including the number of shares offered, the
initial offering price, market price and dividend information.

                                      14
<PAGE>
 
rate or price of one or more specified commodities, currencies or indices) or
a combination of the foregoing), and the terms and conditions upon which such
conversions or exchanges will be effected, including the initial conversion or
exchange prices or rates, the conversion or exchange period and any other
related provisions; (x) the place or places where dividends and other payments
on the Preferred Stock will be payable; and (xi) any additional dividend,
liquidation, redemption and other rights, preferences, privileges, limitations
and restrictions.
 
  All shares of Preferred Stock offered hereby, or issuable upon conversion,
exchange or exercise of Securities, will, when issued, be fully paid and non-
assessable.
 
COMMON STOCK
 
  The holders of Common Stock are entitled to receive such dividends as may be
declared from time to time by the Board of Directors out of funds legally
available therefor. The holders of Common Stock are entitled to one vote per
share on all matters submitted to a vote of shareholders and do not have
cumulative voting rights. Holders of Common Stock are entitled to receive,
upon any liquidation of Federal-Mogul, all remaining assets available for
distribution to shareholders after satisfaction of Federal-Mogul's liabilities
and the preferential rights of any preferred stock that may then be issued and
outstanding. All shares of Common Stock offered hereby, or issuable upon

CERTAIN PROVISIONS
 
  The Restated Articles of Incorporation and Bylaws of Federal-Mogul and the
Rights Agreement contain provisions, summarized below, that could have the
effect of delaying, deterring or preventing a change of control of Federal-
Mogul. This summary does not purport to be complete and is subject to, and
qualified in its entirety by, the provisions of the Restated Articles of
Incorporation and Bylaws and the Rights Agreement.
 
 Federal-Mogul's Articles of Incorporation
 
  Federal-Mogul's Restated Articles of Incorporation provide that the approval
of a business combination (as hereinafter defined) requires (in addition to
any other vote that may be required) the affirmative vote of at least a
majority of the outstanding shares of preferred stock entitled to vote thereon
and Common Stock, voting as a single class. In addition, (a) where the
Restated Articles of Incorporation require the approval of the holder of the
preferred stock or one or more series thereof considered as a separate class,
such business combination shall also require the affirmative vote of at least
a majority of the outstanding shares of the preferred stock of such series
thereof considered as a separate class that are not owned by an Interested
Shareholder (as hereinafter defined) and (b) where applicable law requires
that a transaction be approved by any class or series of Federal-Mogul's stock
or any combination thereof considered as a single class, such transaction
shall also require the affirmative vote of at least a majority of the shares
of each such class or series or combination considered as a single class that
are not owned by the Interested Shareholder.
 
  The voting requirements set forth in the previous paragraph shall not apply
to any business combination if (a) Federal-Mogul's Board of Directors includes
at least one member who was a duly elected and acting member of the Board of
Directors (each being a "Disinterested Director") prior to the time the
Interested Shareholder involved became an Interested Shareholder and such
business combination has been approved by a majority of the Disinterested
Directors and by a majority of the entire Board of Directors, (b) the
aggregate amount of the cash and the fair market value of consideration other
than cash to be received per share by holders of Common Stock in such business
combination shall be at least equal to the Specified Price (as hereinafter
defined) or (c) such business combination has been unanimously approved by the
Board of Directors and the Board has, in the faithful exercise of its
fiduciary duties to the holders of Common Stock, unanimously and expressly
determined that the aggregate amount of the cash and the fair market value of
the consideration other than cash to be received
 
                                      15
<PAGE>
 
per share by holders of Common Stock in such business combination, although
less than the Specified Price, is nonetheless fair to all holders of Common
Stock.
 
  As used above:
 
    "business combination" means (a) any merger or consolidation of Federal-
  Mogul and any subsidiary with or into any Interested Shareholder or any
  corporation which after such merger or consolidation would be an affiliate
  of an Interested Shareholder, (b) any sale lease exchange, mortgage,
  pledge, transfer or other disposition to any Interested Shareholder or its
  affiliate of assets of Federal-Mogul or any subsidiary having a fair market
  value of $1 million or more (except in the ordinary course of business and
  on an arm's-length basis), (c) the issuance or transfer by Federal-Mogul or
  any subsidiary (in one transaction or a series of related transactions) of
  any securities of Federal-Mogul or a subsidiary to any Interested
  Shareholder or its affiliate for cash, securities or property having a fair
  market value of $1 million or more, (d) the adoption of any plan or
  proposal for the liquidation or dissolution of Federal-Mogul as a result of
  which any Interested Shareholder or its affiliate would receive any assets
  of Federal-Mogul other than cash or (e) any reclassification of securities
  (including any reverse stock split) or recapitalization of Federal-Mogul or
  merger or consolidation of Federal-Mogul with any subsidiary or any similar
  transaction (whether or not with an Interested Shareholder) which has the
  effect, directly or indirectly, of increasing the proportion of outstanding
  shares of any equity security of Federal-Mogul or a subsidiary directly
  owned by an Interested Shareholder or its affiliate.
 
    "Interested Shareholder" means a person who on the record date for
  determining the shareholders entitled to vote on a business combination is
  (a) the beneficial owner of 10% or more of the outstanding shares of Common
  Stock, (b) an affiliate of Federal-Mogul and within two years prior to such
  record date beneficially owned 10% or more of the then outstanding shares
  of Common Stock or (c) an assignee or other successor to any shares of
  capital stock of Federal-Mogul which were within two years prior thereto
  beneficially owned by an Interested Shareholder and such assignment or
  succession shall have occurred in one or more transactions not involving a
  public offering.
 
    "Specified Price" means the highest of (a) the highest per share price
  paid or agreed to be paid by such Interested Shareholder to acquire
  beneficial ownership of any shares of Common Stock within the two-year
  period prior to the consummation of the business combination; (b) the per
  share book value of the Common Stock at the end of the fiscal month
  immediately preceding the consummation of such business combination; and
  (c) if the Common Stock of the Interested Shareholder is publicly traded,
  the price per share equal to the earnings per share of Common Stock for the
  four full consecutive fiscal quarters immediately preceding the record date
  for solicitation of votes on such business combination (or, if votes are
  not solicited on such business combination, immediately preceding the
  consummation of such business combination) multiplied by the ratio (if any)
  of the highest published sale price of the Interested Shareholder's common
  stock during its four fiscal quarters immediately preceding such date, to
  the earnings per share of common stock of the Interested Shareholder for
  such four fiscal quarters.
 
 Federal-Mogul's Bylaws
 
  Federal-Mogul's Bylaws contain provisions that govern nominations of
directors by shareholders and presentation of business by shareholders for
consideration at the annual meeting of shareholders. Generally, a shareholder
must give notice of such nomination or business within 60 to 90 days prior to
such meeting, giving specified information as to the shareholder and as to the
person nominated and the business proposed to be brought before the meeting.
 
 Preferred Share Purchase Rights
 
  In 1988, Federal-Mogul's Board of Directors authorized the distribution of
one Preferred Share Purchase Right (a "Right") for each outstanding share of
Common Stock. Each Right entitles the holder thereof to buy
 
                                      16
<PAGE>
 
one-half of one one-hundredth of a share of Series B Junior Participating
Preferred Stock at a price of $70.00. The Rights are governed by the Rights
Agreement.
 
  As distributed, the Rights trade together with the Common Stock. They may be
exercised or traded separately only after the earlier to occur of: (i) 10 days
following a public announcement that a person or group of persons has obtained
the right to acquire 10% or more of the outstanding Common Stock (20% in the
case of certain institutional investors), or (ii) 10 business days (or such
later date as may be determined by action of the Board of Directors) following
the commencement or announcement of an intent to make a tender offer or
exchange offer which would result in beneficial ownership by a person or group
of persons of 10% or more of the outstanding Common Stock. If the acquiring
person or group of persons acquires 10% or more of the Common Stock, each
Right (other than those held by the acquirer) will entitle its holder to
purchase, at the Right's exercise price, shares of Common Stock having a
market value of twice the Right's exercise price. Additionally, if Federal-
Mogul is acquired in a merger or other business combination, each Right (other
than those held by the surviving or acquiring company) will entitle its holder
to purchase, at the Right's exercise price, shares of the acquiring company's
stock (or Common Stock of Federal-Mogul if it is the surviving corporation)
having a market value of twice the Right's exercise price.
 
  Rights may be redeemed at the option of the Board of Directors for $0.005
per Right at any time before a person or group or persons acquires 10% or more
of Federal-Mogul's Common Stock. The Board may amend the Rights at any time
without shareholder approval. The Rights will expire by their terms on
November 14, 1998.
 
  The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group that attempts to acquire Federal-
Mogul in a manner that causes the Rights to become exercisable. Federal-Mogul
believes, however, that the Rights would neither affect any prospective
offeror willing to negotiate with the Board of Directors of Federal-Mogul nor
interfere with any merger or other business combination approved by the Board
of Directors.

Shareholders will be acquired by such Selling Shareholders through conversion
of Series E Stock received as part of the consideration received by them in
the Federal-Mogul acquisition of Fel-Pro. Pursuant to the Registration Rights
Agreement among Federal-Mogul and the Selling Shareholders. Federal-Mogul

compliance with the Registration Rights Agreement, except that the Selling
Shareholders will pay all underwriting discounts and commissions relating to
their shares of Common Stock, brokerage fees, transfer taxes, and the fees and
expenses of any counsel, accountants or other representatives retained by the

Federal-Mogul against certain liabilities, including certain liabilities under
the Securities Act, or will be entitled to contribution in connection
therewith.

<PAGE>
 
                             PLAN OF DISTRIBUTION
 
  Federal-Mogul may sell any of the Securities being offered hereby in any one
or more of the following ways from time to time: (i) through agents; (ii) to
or through underwriters; (iii) through dealers; or (iv) directly to
purchasers.
 
  The Prospectus Supplement with respect to the Securities will set forth the
terms of the offering of the Securities, including the name or names of any
underwriters, dealers or agents; the purchase price of the Securities and the
proceeds to Federal-Mogul from such sale; any underwriting discounts and
commissions or agency fees and other items constituting underwriters' or
agents' compensation; any initial public offering price and any discounts or
concessions allowed or reallowed or paid to dealers and any securities
exchange on which such Securities may be listed. Any initial public offering
price, discounts or concessions allowed or reallowed or paid to dealers may be
changed from time to time.
 
  The distribution of the Securities may be effected from time to time in one
or more transactions at a fixed price or prices, which may be changed, at
market prices prevailing at the time of sale, at prices related to such
prevailing market prices or at negotiated prices.
 
  Offers to purchase Securities may be solicited by agents designated by
Federal-Mogul from time to time. Any such agent involved in the offer or sale
of the Securities in respect of which this Prospectus is delivered will be
named, and any commissions payable by Federal-Mogul to such agent will be set
forth, in the applicable Prospectus Supplement. Unless otherwise indicated in
such Prospectus Supplement, any such agent will be acting on a reasonable best
efforts basis for the period of its appointment. Any such agent may be deemed
to be an underwriter, as that term is defined in the Securities Act of 1933,
of the Securities so offered and sold.
 
  If Securities are sold by means of an underwritten offering, Federal-Mogul
will execute an underwriting agreement with an underwriter or underwriters at
the time an agreement for such sale is reached, and the names of the specific
managing underwriter or underwriters, as well as any other underwriters, and
the terms of the transaction, including commissions, discounts and any other
compensation of the underwriters and dealers, if any, will be set forth in the
Prospectus Supplement which will be used by the underwriters to make resales
of the Securities in respect of which this Prospectus is delivered to the
public. If underwriters are utilized in the sale of the Securities in respect
of which this Prospectus is delivered, the Securities will be acquired by the
underwriters for their own account and may be resold from time to time in one
or more transactions, including negotiated transactions, at fixed public
offering prices or at varying prices determined by the underwriter at the time
of sale. Securities may be offered to the public either through underwriting
syndicates represented by managing underwriters or directly by the managing
underwriters. If any underwriter or underwriters are utilized in the sale of
the Securities, unless otherwise indicated in the Prospectus Supplement, the
underwriting agreement will provide that the obligations of the underwriters
are subject to certain conditions precedent and that the underwriters with
respect to a sale of Securities will be obligated to purchase all such
Securities of a series if any are purchased.
 
  If a dealer is utilized in the sales of the Securities in respect of which
this Prospectus is delivered, Federal-Mogul will sell such Securities to the
dealer as principal. The dealer may then resell such Securities to the public
at varying prices to be determined by such dealer at the time of resale. Any
such dealer may be deemed to be an underwriter, as such term is defined in the
Securities Act, of the Securities so offered and sold. The name of the dealer
and the terms of the transaction will be set forth in the Prospectus
Supplement relating thereto.
 
  Offers to purchase Securities may be solicited directly by Federal-Mogul and
the sale thereof may be made by Federal-Mogul directly to institutional
investors or others, who may be deemed to be underwriters within the meaning
of the Securities Act with respect to any resale thereof. The terms of any
such sales will be described in the Prospectus Supplement relating thereto.
 
  Agents, underwriters and dealers may be entitled under relevant agreements
to indemnification or contribution by Federal-Mogul against certain
liabilities, including liabilities under the Securities Act.
 
                                      20
<PAGE>
 
  Agents, underwriters and dealers may be customers of, engage in transactions
with, or perform services for, Federal-Mogul and its subsidiaries in the
ordinary course of business.
 
  Securities may also be offered and sold, if so indicated in the applicable
Prospectus Supplement, in connection with a remarketing upon their purchase,
in accordance with a redemption or repayment pursuant to their terms, or
otherwise, by one or more firms ("remarketing firms"), acting as principals
for their own accounts or as agents for Federal-Mogul. Any remarketing firm
will be identified and the terms of its agreement, if any, with its
compensation will be described in the applicable Prospectus Supplement.
Remarketing firms may be deemed to be underwriters, as such term is defined in
the Securities Act, in connection with the Securities remarketed thereby.
Remarketing firms may be entitled under agreements which may be entered into
with Federal-Mogul to indemnification or contribution by Federal-Mogul against
certain civil liabilities, including liabilities under the Securities Act, and
may be customers of, engage in transactions with or perform services for
Federal-Mogul and its subsidiaries in the ordinary course of business.
 
  If so indicated in the applicable Prospectus Supplement, Federal-Mogul may
authorize agents, underwriters or dealers to solicit offers by certain types
of institutions to purchase Securities from Federal-Mogul at the public
offering prices set forth in the applicable Prospectus Supplement pursuant to
delayed delivery contracts ("Contracts") providing for payment and delivery on
a specified date or dates in the future. A commission indicated in the
applicable Prospectus Supplement will be paid to underwriters, dealers and
agents soliciting purchases of Securities pursuant to Contracts accepted by
Federal-Mogul.
 
  The Selling Shareholders have informed the Company that, unless otherwise
specified in a Prospectus Supplement, they intend to dispose of their shares
of Common Stock offered hereby (the "Shares") through underwriters and that
they will execute an underwriting agreement with an underwriter or
underwriters at the time an agreement for such sale is reached. The names of
the specific managing underwriter or underwriters, as well as any other
underwriters, and the terms of the transaction, including commissions,
discounts and any other compensation of the underwriters and dealers, if any,
will be set forth in the Prospectus Supplement which will be used by the
underwriters to make resales of the Shares in respect of which this Prospectus
is delivered to the public. The Shares will be acquired by the underwriters
for their own account and may be resold from time to time in one or more
transactions, including negotiated transactions, at fixed public offering
prices or at varying prices determined by the underwriter at the time of sale.
Shares may be offered to the public either through underwriting syndicates
represented by managing underwriters or directly by the managing underwriters.
Unless otherwise indicated in the Prospectus Supplement, the underwriting
agreement will provide that the obligations of the underwriters are subject to
certain conditions precedent and that the underwriters with respect to a sale
of Shares will be obligated to purchase all such Shares if any are purchased.
